Detailed Description: TECHNICAL FIELD Embodiments described herein relate to methods and apparatus for transmitting at least one data stream comprising a plurality of samples between a first wireless device and a second wireless device using machine-to-machine communication. BACKGROUND Generally, all terms used herein are to be interpreted according to their ordinary meaning in the relevant technical field, unless a different meaning is clearly given and/or is implied from the context in which it is used. All references to a/an/the element, apparatus, component, means, step, etc. are to be interpreted openly as referring to at least one instance of the element, apparatus, component, means, step, etc., unless explicitly stated otherwise. The steps of any methods disclosed herein do not have to be performed in the exact order disclosed, unless a step is explicitly described as following or preceding another step and/or where it is implicit that a step must follow or precede another step. Any feature of any of the embodiments disclosed herein may be applied to any other embodiment, wherever appropriate. Likewise, any advantage of any of the embodiments may apply to any other embodiments, and vice versa. Other objectives, features and advantages of the enclosed embodiments will be apparent from the following description. Machine-to-machine (M2M) communication may make up a large part of some new types of services and use cases that 5G systems will address. M2M is envisioned to enable control and automation of dynamic processes in various fields, for example, industrial process automation and manufacturing, energy distribution, and intelligent transport systems (ITS). Ultra-reliable low-latency communications (URLLC) is one important enabler supporting these new services. An example of stringent requirements on URLLC currently being studied in 3GPP RAN WG is 99.999% reliability under the radio latency bound of 1 millisecond. Specifically, electrical grids substation automation (SA) is commonly used to control, protect and monitor substations. Latency and reliability may be considered as key components of an SA communication system for uninterrupted power supply from the power transmission. In SA, many sampling values are collected from a device (for example, a transformer) in timely manner and sent over a wired network. For example, in a reliable SA scenario, sampled values may be transmitted with a high rate corresponding to the sampling rate of the current and voltage through the device, for example 80 messages per cycle being 4000 messages/sec for a 50 Hz system. Currently, URLLC use conventional wired solutions which rely on a physical deployment of the wired connections. These are less convenient than wireless solutions as they have a rigid deployment, which can be costly and thus may not be considered appropriate for smart electrical systems, for example, for substation automation. This motivates the need for flexible, scalable, and cost effective wireless solutions. In smart SA in particular, devices may send monitoring or reporting data (sample values) in an uplink-dominant state fashion using short session times and short packets. However, the transmission of high rate sampling values in such a high rate of data packets is disallowed using LTE as it elevates overhead and resource waste. Transmission of high rate sampling values may be used in precise and synchronous time-critical monitoring systems, for example as previously mentioned, in factory automation and smart electrical grid environments. In the majority of these applications, sampling data transmissions are performed via a wired connection, for example using an Ethernet-based serial link. These wired solutions have inherent advantages, for example, the capability to meet tight quality of service (QoS) requirements in terms of delay and reliability. These quality of service requirements may not be so easily achievable using wireless solutions. However, one disadvantage of a wired infrastructure is that the deployment and any future modifications, for example, the addition of new sampling device, would be costly and complicated to implement. QoS constraints applied to high-rate sampled data used, for example, for monitoring the operation of a digital substation are mainly described in terms of latency and reliability. For example, the domain communication delay for sampled values may be constrained within a 3 ms margin, in order to react in a timely manner on the changing conditions or failures. An additional QoS metric for sampled values may be reliability. The reliability may be considered to be a measure of how well the equipment or system performs its intended function, under specified conditions, for a specified period of time. In time-critical functions, reliability may also be measured in terms of a maximum allowed response time for an action. Thus, for sampling data transmissions, reliability may be based on a percentage of lost packets and packets outside of the delay margin. Even though the amount of lost packets requirement may be a relatively low barrier, for example a less than 50% success rate in which no consecutive packets are lost, the extremely short delay boundary may still make the QoS requirements difficult to fulfill. 5th generation (5G) radio access technologies, if compared to previous generations of wireless communication networks, are capable of implementing more flexible resource allocation and transmission granularity both in time and frequency domains. On top of that, various repetition and traffic prioritization schemes guarantee low-latency and high reliability of data transfer. There currently exist certain challenge(s). For example, a high sampling rate leads to a high rate of wireless data packets, which may be challenging given high QoS constraints. Wire-based services have a predefined format that in some circumstances it may be required to follow. Certain aspects of the present disclosure and their embodiments may provide solutions to these or other challenges.

According to some embodiments there is provided a first wireless device for transmitting at least one data stream comprising a plurality of samples to a second wireless device using machine-to-machine communication. The first wireless device comprises processing circuitry configured to: receive the at least one data stream; generate a first data packet comprising N of the plurality of samples, wherein N is an integer value of greater than or equal to 2; and transmit the first data packet to the second wireless device.

DESCRIPTION Some of the embodiments contemplated herein will now be described more fully with reference to the accompanying drawings. Other embodiments, however, are contained within the scope of the subject matter disclosed herein, the disclosed subject matter should not be construed as limited to only the embodiments set forth herein; rather, these embodiments are provided by way of example to convey the scope of the subject matter to those skilled in the art. There are, proposed herein, various embodiments which address one or more of the issues disclosed herein. Certain embodiments may provide one or more of the following technical advantage(s). For example, embodiments provided herein a wireless connection which can efficiently be used to provide high-rate sampling services within QoS constraints. A first wireless device, which may for example be referred to as a sample packing transmitting device (SPTD), may be configured to bundle multiple samples of a data stream into less packets than the number of samples, thereby enabling a consistent compound flow which makes it possible to keep the connection with the second wireless device, which may for example be referred to as a sample un-packing receiving device (SURD) (e.g., base station or a wireless device), alive, thus reducing the signalling due to multiple sessions being initiated and ended. Furthermore, by bundling a plurality of samples into a larger packet, the first wireless device may use a single access request to the second wireless device, thus proportionally reducing the transmission overhead. Furthermore, by having fewer packets being transmitted over the wireless channel between the first wireless device and the second wireless device, the overall network latency and resource usage is reduced. Furthermore, the first wireless device may act as proxy device and therefore reduce total number of requests. Furthermore, by having bundling and unbundling processes comprised within existing network devices leads to a reduction in high-cost cellular communication modems. FIG. 1 illustrates a wireless M2M communication link between a first wireless device (SPTD) and a second wireless device (SURD). As illustrated in FIG. 1, in embodiments described herein, a number (N) of samples are bundled by the first wireless device (SPTD), into a packet that can be tailored to timings with the radio interface and the requirements of the second wireless device (SURD). Firstly, the samples (S1 to SN) are collected by the first wireless device. The samples may then be buffered until N (the value of which can be a fixed or dynamically chosen number) samples are stored, and then some or all of these samples may be bundled together into a packet. In FIG. 1 the samples S1 to SN are bundled into a packet and transmitted to the second wireless device. The packet may then be transmitted over the wireless channel to the second wireless device. The second wireless device may then unbundle, unpack or extract the samples from the packet. These samples may be buffered whilst the extraction is taking place. The samples may then be reordered into the same order as they were received by the first wireless device, and with the same time difference between all samples as originally received by the first wireless device. FIG. 2 illustrates a method in a first wireless device for transmitting at least one data stream comprising a plurality of samples to a second wireless device using machine-to-machine communication. The first wireless device may be referred to as a transmitting wireless device or a bundling wireless device. The first wireless device may aim to improve the system utilization by exploiting the existing device (e.g., reading sample values from sensor board) capabilities. Therefore, the first wireless device may be configured to package streams of samples over time and act as sample aggregator. At the time of receiving a scheduling request (SR) for transmission, the first wireless device may bundle a number of N of samples in its transmission buffer to a single packet. For example, in step 201 the first wireless device receives the at least one data stream. It will be appreciated that in some examples there may be more than one data stream, and that the first wireless device may aggregate the data streams for transmission to the second wireless device. In step 202, the first wireless device generates a first data packet comprising N of the plurality of samples, wherein N is an integer value of greater than or equal to 2. In particular, the step of generating may comprise bundling the N samples into the first data packet according to a predetermined pattern. In step 203, the first wireless device transmits the first data packet to the second wireless device. FIG. 3 illustrates a method performed by a second wireless device for receiving at least one data stream comprising a plurality of samples from a first wireless device using machine-to-machine communication. To maintain the requirements (for example, latency requirements) of the wireless channel, the second wireless device, for example the second wireless device illustrated in FIG. 1, may be configured such that it expects packets comprising multiple small size samples. The second wireless device may be configured to unpack the samples in according to the same predetermined pattern used by the first wireless device to package the samples before transmission. The main role of second wireless device is to unpack those samples such that a processing device receiving the unpacked at least one data stream, receives the at least one data stream in the same way in which they were received at the first wireless device. For example, the second wireless device configured to perform the method illustrated in FIG. 3, may be the second wireless device in FIG. 1 and may be communicating to receive data streams from the first wireless device illustrated in FIG. 1 (which may be configured to perform the method as illustrated in FIG. 2). In step 301, the second wireless device receives at least a first data packet from the first wireless device. In step 302, the second wireless device extracts N samples from the first data packet, wherein N is an integer value of greater than or equal to 2. In step 303, the second wireless device then generates the at least one data stream based on the extracted N samples. In particular, the second wireless device may de-bundle (or unpack) the N samples into the at least one first data stream according to a predetermined pattern. In other words, the first wireless device on the transmitting side collects sampling data packets from a sampling device in a time window and bundles them for transmission over a wireless channel to the second wireless device. The second wireless device on the receiving side then unbundles the samples out of the data packets, according to the same predetermined pattern used by the first wireless device to bundle the samples, and sends them on to an evaluation device in an expected time pattern. It will be appreciated that the predetermined pattern used to bundle one packet may be different to a predetermined pattern used to bundle a different packet, even in the same data stream. For example, some packets may comprise one sample, whereas other packets may comprise more than one sample. FIG. 4 illustrates an example of two data streams, sampled signal 1 and sampled signal 2, for which the samples are bundled with only one sample from each stream in each packet. In this example, therefore, the number of packets is equal to the number of samples in a single stream. One sample is taken from each data stream, and both of these samples are bundled into a packet. For example, the first sample from each data stream is bundled into Packet 1, the second sample from each data stream is bundled into packet 2, and so on and so forth until the M+4 sample from each data stream is bundled into packet M+4. FIG. 5 illustrates an example where two data streams, sampled signal 1 and sampled signal 2, are bundled with two samples from each stream in each packet. FIG. 5 therefore demonstrates that by bundling N samples into one packet, the total number of packets is reduced by N. In this case N=2. It is typical in industrial applications that the receiving wireless device, i.e. the second wireless device, may tolerate occasional lost packets or samples, but if more than a certain number of samples are lost in a row (for example 2 or 3 samples in a row) the second wireless device may interpret this to mean that the wireless channel is an unreliable communication link and the second wireless device may then perform an emergency action, for example, an automatic emergency stop or similar. If the second wireless device has this characteristic, the bundling method may become sensitive to transmission errors on the wireless channel. If, for example, 3 samples are bundled together in each packet, a single lost packet over the wireless channel, would result in 3 consecutive lost samples, which may then trigger an emergency action even if the overall loss rate of over the wireless channel is acceptable. In the example illustrated in FIG. 5, therefore, in order to meet the reliability requirement and avoid loss of several consecutive samples, each packet bundles only odd or even samples. The predetermined pattern of bundling the samples in this example, therefore, comprises bundling two odd samples and two even samples together. If, for another example, the timing requirements allow for four samples to be bundled together, a single data stream may be bundled as follows: Packet 1: S1, S3, S5, S7 Packet 2: S2, S4, S6, S8 Packet 3: S9, S11, S13, S15 Packet 4: S10, S12, S14, S16 It will be appreciated avoiding loss of two consecutive samples if a packet is lost may be achieved in general by an example predetermined pattern which comprises bundling samples identified by a sampling ID (sID) of sID=k+stepover*m wherein stepover is an integer value of greater than or equal to 2, k is an sID of a first sample to be bundled into the data packet, and m=0:N−1. In this example, the first wireless device may be configured to buffer k+stepover*m samples in order to generate the packets appropriately. In some examples, the predetermined pattern used to bundle and/or unbundle the samples from the packets is fixed, for example, on set up of the first wireless device and the second wireless device. However, in some embodiments the predetermined pattern may be determined dynamically, for example based on quality of service requirements associated with a particular transmission. For example, the first wireless device may be configured to transmit an indication of the predetermined pattern which it has used to bundle the samples to the second wireless device. This then allows the second wireless device to reverse the predetermined pattern used by the first wireless device when unbundling the samples at the receiving end. For example, the first wireless device may be configured to transmit an indication of the value of k and/or N used in bundling the samples to the second wireless device. In some examples, the size of N may be as high as the delay requirement for sampled values allows, as will be described later. The predetermined pattern used to bundle packets may be adapted based on QoS requirements and the error rate of the wireless channel between the first wireless device and the second wireless device. FIG. 6 illustrates an example flow diagram for bundling two sampling streams, sample stream 1 and sample stream 2 for transmission from a first wireless device, the SPTD, to a second wireless device, the SURD. In this example, the SPTD receive samples S1, S3 and S5 from sampling stream 2 and samples S2, S4 and S6 from sample stream 1. The SPTD then bundles these samples into two packets. The first packet comprises the samples S1, S2 and S3, and the second sample comprises the samples S4, S5 and S6. These two packets are then transmitted to the SURD for unbundling. In this example therefore the predetermined pattern of bundling comprises bundling a single sample from the first data stream with two samples from the second data stream into the first packet, and then bundling two samples from a first data stream with a sample from a second data stream into the second packet. In some examples, a high rate of samples may be received by the first wireless device, but not at a very high data rate. For example, an application may generate small packets every 0.25 ms or 0.5 ms. If these packets are transmitted over LTE with a transmission time interval (TTI) of 1 ms a bundling of 4 or 2 packets, respectively, to be sent together in each packet to send one packet per TTI. However, to increase the robustness, when the data rate is low, each packet may be duplicated in at least one subsequent TTI. In this way, if the transmission in one TTI is lost due to interference, the data in the TTI may still be available in the at least one other TTI. In other words, the first wireless device may be configured to transmit the first data packet in a first transmission time interval; and transmit a repeat of the first data packet in a second transmission time interval after the first transmission time interval. In some examples, the value of N depends on the application (e.g., factory automation, robotic control application etc.) latency and reliability requirements of a particular data stream. If applications are tied to lower latency values, the time period for bundling a packet may be required to remain low. It will be appreciated that the larger the value of N, (and the larger the value of k), the higher the delay incurred in bundling the packets, as more samples must be buffered before the packets can be generated. Since the samples are delivered to their end destination, by the second wireless device, in the same order as they were received at the first wireless device, each sample may need to wait an additional time in the buffer at the first wireless device apparatus for the packet to be formed and a time in the buffer at the second wireless device in order to be placed back into the data stream with the correct timing. This extra delay may be the same for all samples (otherwise they would end up in the wrong order) and this delay may be calculated as: d bunaling = 1 r * N where N is the number of samples in a packet, r is the sampling rate (i.e., the number of samples that arrive per second at the first wireless device). FIG. 7 illustrates an example where each sample is of same size (for example, the same number of bits). In particular, FIG. 6 illustrates the delay due to the bundling as a function of the number of samples in a packet for the case where 4000 samples per second is received at the first wireless device. In some embodiments therefore the the value of N may satisfy the following: ⁢ N ≤ ⌊ bits_per ⁢ _packet bits_per ⁢ _sample ⌋ , here bits_per_packet is a number of bits per transmission time interval and bits_per_sample is a number of bits in each of the plurality of samples. Note the floor function, rounding the fraction to the below integer value. This means that the value of N used may be based on the number of bits that fits into a packet that is optimized for transmission by the radio technology used to generate the wireless channel. In one embodiment this is done by first considering the number of bits needed to describe each sample (bits_per_sample) and the number of bits (bits_per_packet) that can be transported in a packet that is possible to transmit in a TTI (transmission time interval) using the radio access technology. The latter depends on the available bandwidth. In some embodiments the value of N may additionally or alternatively satisfy the following: N≤r*dbundling, wherein r is a sampling rate of the at least one data stream and dbundling is a maximum delay allowed for bundling of the at least one data stream. In other words, if ⌊ bits_per ⁢ _packet bits_per ⁢ _sample ⌋ ≤ r * d bundling ⁢ ⁢ then ⁢ ⁢ ⌊ bits_per ⁢ _packet bits_per ⁢ _sample ⌋ may be used as the value of N. However, if ⌊ bits_per ⁢ _packet bits_per ⁢ _sample ⌋ > r * d bundling then a value of N which satisfies N≤r*dbundling may be used. For example, FIG. 8 illustrates the maximum allowed bundle size, N, as a function of the delay requirement imposed on the bundle delay by the total delay budget. In this example the delay budget allows for 5 ms which for 4000 samples per seconds imply a maximum size of 20 samples per packet. As previously mentioned, in some embodiments, the value of N is fixed on set up of the first and second wireless device. However, in some embodiments, the value of N may be determined dynamically. For example, the first wireless device may be configured to receive an indication of the maximum delay dbundling (which may be specific for a particular data stream or application), receive an indication of the sampling rate r of the at least one data stream, and may then calculate the value of N as described above. The first wireless device may then transmit an indication of the value of N to the second wireless device. There is therefore provided a first wireless device configured to receive or determine a number of samples N to be bundled into a packet, receive the at least one data stream comprising a plurality of samples, bundle the samples into packets in comprising N samples, and transmit the data packets to a second wireless device. There is therefore also provided a second wireless device configured to unbundling data packets received from the first wireless device to generate at least one data stream comprising a plurality of samples, where the at least one data stream is the same as the at least one data stream received at the first wireless device. FIG. 9 illustrates a wireless network in accordance with some embodiments. Although the subject matter described herein may be implemented in any appropriate type of system using any suitable components, the embodiments disclosed herein are described in relation to a wireless network, such as the example wireless network illustrated in FIG. 9. For simplicity, the wireless network of FIG. 9 only depicts network 906, network nodes 960 and 960b, and WDs 910, 910b, and 910c. In practice, a wireless network may further include any additional elements suitable to support communication between wireless devices or between a wireless device and another communication device, such as a landline telephone, a service provider, or any other network node or end device. Of the illustrated components, network node 960 and wireless device (WD) 910 are depicted with additional detail. The wireless network may provide communication and other types of services to one or more wireless devices to facilitate the wireless devices' access to and/or use of the services provided by, or via, the wireless network. The wireless network may comprise and/or interface with any type of communication, telecommunication, data, cellular, and/or radio network or other similar type of system. In some embodiments, the wireless network may be configured to operate according to specific standards or other types of predefined rules or procedures. Thus, particular embodiments of the wireless network may implement communication standards, such as Global System for Mobile Communications (GSM), Universal Mobile Telecommunications System (UMTS), Long Term Evolution (LTE), and/or other suitable 2G, 3G, 4G, or 5G standards; wireless local area network (WLAN) standards, such as the IEEE 802.11 standards; and/or any other appropriate wireless communication standard, such as the Worldwide Interoperability for Microwave Access (WiMax), Bluetooth, Z-Wave and/or ZigBee standards. Network 906 may comprise one or more backhaul networks, core networks, IP networks, public switched telephone networks (PSTNs), packet data networks, optical networks, wide-area networks (WANs), local area networks (LANs), wireless local area networks (WLANs), wired networks, wireless networks, metropolitan area networks, and other networks to enable communication between devices. Network node 960 and WD 910 comprise various components described in more detail below. These components work together in order to provide network node and/or wireless device functionality, such as providing wireless connections in a wireless network. In different embodiments, the wireless network may comprise any number of wired or wireless networks, network nodes, base stations, controllers, wireless devices, relay stations, and/or any other components or systems that may facilitate or participate in the communication of data and/or signals whether via wired or wireless connections. As used herein, network node refers to equipment capable, configured, arranged and/or operable to communicate directly or indirectly with a wireless device and/or with other network nodes or equipment in the wireless network to enable and/or provide wireless access to the wireless device and/or to perform other functions (e.g., administration) in the wireless network. Examples of network nodes include, but are not limited to, access points (APs) (e.g., radio access points), base stations (BSs) (e.g., radio base stations, Node Bs, evolved Node Bs (eNBs) and NR NodeBs (gNBs)). Base stations may be categorized based on the amount of coverage they provide (or, stated differently, their transmit power level) and may then also be referred to as femto base stations, pico base stations, micro base stations, or macro base stations. A base station may be a relay node or a relay donor node controlling a relay. A network node may also include one or more (or all) parts of a distributed radio base station such as centralized digital units and/or remote radio units (RRUs), sometimes referred to as Remote Radio Heads (RRHs). Such remote radio units may or may not be integrated with an antenna as an antenna integrated radio. Parts of a distributed radio base station may also be referred to as nodes in a distributed antenna system (DAS). Yet further examples of network nodes include multi-standard radio (MSR) equipment such as MSR BSs, network controllers such as radio network controllers (RNCs) or base station controllers (BSCs), base transceiver stations (BTSs), transmission points, transmission nodes, multi-cell/multicast coordination entities (MCEs), core network nodes (e.g., MSCs, MMEs), O&M nodes, OSS nodes, SON nodes, positioning nodes (e.g., E-SMLCs), and/or MDTs. As another example, a network node may be a virtual network node as described in more detail below. More generally, however, network nodes may represent any suitable device (or group of devices) capable, configured, arranged, and/or operable to enable and/or provide a wireless device with access to the wireless network or to provide some service to a wireless device that has accessed the wireless network. In FIG. 9, network node 960 includes processing circuitry 970, device readable medium 980, interface 990, auxiliary equipment 984, power source 986, power circuitry 987, and antenna 962. Although network node 960 illustrated in the example wireless network of FIG. 9 may represent a device that includes the illustrated combination of hardware components, other embodiments may comprise network nodes with different combinations of components. It is to be understood that a network node comprises any suitable combination of hardware and/or software needed to perform the tasks, features, functions and methods disclosed herein. Moreover, while the components of network node 960 are depicted as single boxes located within a larger box, or nested within multiple boxes, in practice, a network node may comprise multiple different physical components that make up a single illustrated component (e.g., device readable medium 980 may comprise multiple separate hard drives as well as multiple RAM modules). Similarly, network node 960 may be composed of multiple physically separate components (e.g., a NodeB component and a RNC component, or a BTS component and a BSC component, etc.), which may each have their own respective components. In certain scenarios in which network node 960 comprises multiple separate components (e.g., BTS and BSC components), one or more of the separate components may be shared among several network nodes. For example, a single RNC may control multiple NodeB's. In such a scenario, each unique NodeB and RNC pair, may in some instances be considered a single separate network node. In some embodiments, network node 960 may be configured to support multiple radio access technologies (RATs). In such embodiments, some components may be duplicated (e.g., separate device readable medium 980 for the different RATs) and some components may be reused (e.g., the same antenna 962 may be shared by the RATs). Network node 960 may also include multiple sets of the various illustrated components for different wireless technologies integrated into network node 960, such as, for example, GSM, WCDMA, LTE, NR, WiFi, or Bluetooth wireless technologies. These wireless technologies may be integrated into the same or different chip or set of chips and other components within network node 960. Processing circuitry 970 is configured to perform any determining, calculating, or similar operations (e.g., certain obtaining operations) described herein as being provided by a network node. These operations performed by processing circuitry 970 may include processing information obtained by processing circuitry 970 by, for example, converting the obtained information into other information, comparing the obtained information or converted information to information stored in the network node, and/or performing one or more operations based on the obtained information or converted information, and as a result of said processing making a determination. Processing circuitry 970 may comprise a combination of one or more of a microprocessor, controller, microcontroller, central processing unit, digital signal processor, application-specific integrated circuit, field programmable gate array, or any other suitable computing device, resource, or combination of hardware, software and/or encoded logic operable to provide, either alone or in conjunction with other network node 960 components, such as device readable medium 980, network node 960 functionality. For example, processing circuitry 970 may execute instructions stored in device readable medium 980 or in memory within processing circuitry 970. Such functionality may include providing any of the various wireless features, functions, or benefits discussed herein. In some embodiments, processing circuitry 970 may include a system on a chip (SOC). In some embodiments, processing circuitry 970 may include one or more of radio frequency (RF) transceiver circuitry 972 and baseband processing circuitry 974. In some embodiments, radio frequency (RF) transceiver circuitry 972 and baseband processing circuitry 974 may be on separate chips (or sets of chips), boards, or units, such as radio units and digital units. In alternative embodiments, part or all of RF transceiver circuitry 972 and baseband processing circuitry 974 may be on the same chip or set of chips, boards, or units In certain embodiments, some or all of the functionality described herein as being provided by a network node, base station, eNB or other such network device may be performed by processing circuitry 970 executing instructions stored on device readable medium 980 or memory within processing circuitry 970. In alternative embodiments, some or all of the functionality may be provided by processing circuitry 970 without executing instructions stored on a separate or discrete device readable medium, such as in a hard-wired manner. In any of those embodiments, whether executing instructions stored on a device readable storage medium or not, processing circuitry 970 can be configured to perform the described functionality. The benefits provided by such functionality are not limited to processing circuitry 970 alone or to other components of network node 960, but are enjoyed by network node 960 as a whole, and/or by end users and the wireless network generally. Device readable medium 980 may comprise any form of volatile or non-volatile computer readable memory including, without limitation, persistent storage, solid-state memory, remotely mounted memory, magnetic media, optical media, random access memory (RAM), read-only memory (ROM), mass storage media (for example, a hard disk), removable storage media (for example, a flash drive, a Compact Disk (CD) or a Digital Video Disk (DVD)), and/or any other volatile or non-volatile, non-transitory device readable and/or computer-executable memory devices that store information, data, and/or instructions that may be used by processing circuitry 970. Device readable medium 980 may store any suitable instructions, data or information, including a computer program, software, an application including one or more of logic, rules, code, tables, etc. and/or other instructions capable of being executed by processing circuitry 970 and, utilized by network node 960. Device readable medium 980 may be used to store any calculations made by processing circuitry 970 and/or any data received via interface 990. In some embodiments, processing circuitry 970 and device readable medium 980 may be considered to be integrated. Interface 990 is used in the wired or wireless communication of signalling and/or data between network node 960, network 906, and/or WDs 910. As illustrated, interface 990 comprises port(s)/terminal(s) 994 to send and receive data, for example to and from network 906 over a wired connection. Interface 990 also includes radio front end circuitry 992 that may be coupled to, or in certain embodiments a part of, antenna 962. Radio front end circuitry 992 comprises filters 998 and amplifiers 996. Radio front end circuitry 992 may be connected to antenna 962 and processing circuitry 970. Radio front end circuitry may be configured to condition signals communicated between antenna 962 and processing circuitry 970. Radio front end circuitry 992 may receive digital data that is to be sent out to other network nodes or WDs via a wireless connection. Radio front end circuitry 992 may convert the digital data into a radio signal having the appropriate channel and bandwidth parameters using a combination of filters 998 and/or amplifiers 996. The radio signal may then be transmitted via antenna 962. Similarly, when receiving data, antenna 962 may collect radio signals which are then converted into digital data by radio front end circuitry 992. The digital data may be passed to processing circuitry 970. In other embodiments, the interface may comprise different components and/or different combinations of components. In certain alternative embodiments, network node 960 may not include separate radio front end circuitry 992, instead, processing circuitry 970 may comprise radio front end circuitry and may be connected to antenna 962 without separate radio front end circuitry 992. Similarly, in some embodiments, all or some of RF transceiver circuitry 972 may be considered a part of interface 990. In still other embodiments, interface 990 may include one or more ports or terminals 994, radio front end circuitry 992, and RF transceiver circuitry 972, as part of a radio unit (not shown), and interface 990 may communicate with baseband processing circuitry 974, which is part of a digital unit (not shown). Antenna 962 may include one or more antennas, or antenna arrays, configured to send and/or receive wireless signals. Antenna 962 may be coupled to radio front end circuitry 990 and may be any type of antenna capable of transmitting and receiving data and/or signals wirelessly. In some embodiments, antenna 962 may comprise one or more omni-directional, sector or panel antennas operable to transmit/receive radio signals between, for example, 2 GHz and 66 GHz. An omni-directional antenna may be used to transmit/receive radio signals in any direction, a sector antenna may be used to transmit/receive radio signals from devices within a particular area, and a panel antenna may be a line of sight antenna used to transmit/receive radio signals in a relatively straight line. In some instances, the use of more than one antenna may be referred to as MIMO. In certain embodiments, antenna 962 may be separate from network node 960 and may be connectable to network node 960 through an interface or port. Antenna 962, interface 990, and/or processing circuitry 970 may be configured to perform any receiving operations and/or certain obtaining operations described herein as being performed by a network node. Any information, data and/or signals may be received from a wireless device, another network node and/or any other network equipment. Similarly, antenna 962, interface 990, and/or processing circuitry 970 may be configured to perform any transmitting operations described herein as being performed by a network node. Any information, data and/or signals may be transmitted to a wireless device, another network node and/or any other network equipment. Power circuitry 987 may comprise, or be coupled to, power management circuitry and is configured to supply the components of network node 960 with power for performing the functionality described herein. Power circuitry 987 may receive power from power source 986. Power source 986 and/or power circuitry 987 may be configured to provide power to the various components of network node 960 in a form suitable for the respective components (e.g., at a voltage and current level needed for each respective component). Power source 986 may either be included in, or external to, power circuitry 987 and/or network node 960. For example, network node 960 may be connectable to an external power source (e.g., an electricity outlet) via an input circuitry or interface such as an electrical cable, whereby the external power source supplies power to power circuitry 987. As a further example, power source 986 may comprise a source of power in the form of a battery or battery pack which is connected to, or integrated in, power circuitry 987. The battery may provide backup power should the external power source fail. Other types of power sources, such as photovoltaic devices, may also be used. Alternative embodiments of network node 960 may include additional components beyond those shown in FIG. 9 that may be responsible for providing certain aspects of the network node's functionality, including any of the functionality described herein and/or any functionality necessary to support the subject matter described herein. For example, network node 960 may include user interface equipment to allow input of information into network node 960 and to allow output of information from network node 960. This may allow a user to perform diagnostic, maintenance, repair, and other administrative functions for network node 960. As used herein, wireless device (WD) refers to a device capable, configured, arranged and/or operable to communicate wirelessly with network nodes and/or other wireless devices. Unless otherwise noted, the term WD may be used interchangeably herein with user equipment (UE). Communicating wirelessly may involve transmitting and/or receiving wireless signals using electromagnetic waves, radio waves, infrared waves, and/or other types of signals suitable for conveying information through air. In some embodiments, a WD may be configured to transmit and/or receive information without direct human interaction. For instance, a WD may be designed to transmit information to a network on a predetermined schedule, when triggered by an internal or external event, or in response to requests from the network. Examples of a WD include, but are not limited to, a smart phone, a mobile phone, a cell phone, a voice over IP (VoIP) phone, a wireless local loop phone, a desktop computer, a personal digital assistant (PDA), a wireless cameras, a gaming console or device, a music storage device, a playback appliance, a wearable terminal device, a wireless endpoint, a mobile station, a tablet, a laptop, a laptop-embedded equipment (LEE), a laptop-mounted equipment (LME), a smart device, a wireless customer-premise equipment (CPE), a vehicle-mounted wireless terminal device, etc. A WD may support device-to-device (D2D) communication, for example by implementing a 3GPP standard for sidelink communication, vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-everything (V2X) and may in this case be referred to as a D2D communication device. As yet another specific example, in an Internet of Things (IoT) scenario, a WD may represent a machine or other device that performs monitoring and/or measurements, and transmits the results of such monitoring and/or measurements to another WD and/or a network node. The WD may in this case be a machine-to-machine (M2M) device, which may in a 3GPP context be referred to as an MTC device. As one particular example, the WD may be a UE implementing the 3GPP narrow band internet of things (NB-IoT) standard. Particular examples of such machines or devices are sensors, metering devices such as power meters, industrial machinery, or home or personal appliances (e.g. refrigerators, televisions, etc.) personal wearables (e.g., watches, fitness trackers, etc.). In other scenarios, a WD may represent a vehicle or other equipment that is capable of monitoring and/or reporting on its operational status or other functions associated with its operation. A WD as described above may represent the endpoint of a wireless connection, in which case the device may be referred to as a wireless terminal. Furthermore, a WD as described above may be mobile, in which case it may also be referred to as a mobile device or a mobile terminal.

Radio front end circuitry 912 may be coupled to or a part of antenna 911. In some embodiments, WD 910 may not include separate radio front end circuitry 912; rather, processing circuitry 920 may comprise radio front end circuitry and may be connected to antenna 911. Similarly, in some embodiments, some or all of RF transceiver circuitry 922 may be considered a part of interface 914. Radio front end circuitry 912 may receive digital data that is to be sent out to other network nodes or WDs via a wireless connection. Radio front end circuitry 912 may convert the digital data into a radio signal having the appropriate channel and bandwidth parameters using a combination of filters 918 and/or amplifiers 916. The radio signal may then be transmitted via antenna 911. Similarly, when receiving data, antenna 911 may collect radio signals which are then converted into digital data by radio front end circuitry 912. The digital data may be passed to processing circuitry 920. In other embodiments, the interface may comprise different components and/or different combinations of components. Processing circuitry 920 may comprise a combination of one or more of a microprocessor, controller, microcontroller, central processing unit, digital signal processor, application-specific integrated circuit, field programmable gate array, or any other suitable computing device, resource, or combination of hardware, software, and/or encoded logic operable to provide, either alone or in conjunction with other WD 910 components, such as device readable medium 930, WD 910 functionality. Such functionality may include providing any of the various wireless features or benefits discussed herein. For example, processing circuitry 920 may execute instructions stored in device readable medium 930 or in memory within processing circuitry 920 to provide the functionality disclosed herein. As illustrated, processing circuitry 920 includes one or more of RF transceiver circuitry 922, baseband processing circuitry 924, and application processing circuitry 926. In other embodiments, the processing circuitry may comprise different components and/or different combinations of components.
