-6 - 64.8 - 59.8 - 56.8 New Radio Access RF and Transceiver Design Considerations 689 met for each consecutive application of a single instance of the reference measurement channel mapped to disjoint frequency ranges with a width corresponding to the number of resource blocks of each reference measurement channel, except for one instance that might overlap another instance to cover the full BS channel bandwidth [5]. There are a set of requirements for the BS and the device, which define the receiver ability to receive a wanted signal in the presence of a stronger interfering signal. There are differ- ent interference scenarios depending on the frequency offset of the interferer from the wanted signal, where different types of receiver impairments will affect the performance. A set of combinations of the interfering signals with different bandwidths can be defined which model the practical scenarios that are encountered within and outside of the BS/ device receiver bandwidth. While the types of requirements are very similar for the BS and the device, the signal levels are different since the interference scenarios for the BS and device can vary. The following requirements are defined for NR base stations and the devices. In all cases where the interfering signal is an NR signal, it has the same or smaller bandwidth (less than 20 MHz) relative to the desired signal [5]: In-band/Out-of-band Blocking: Blocking refers to the scenario where strong interfering signals are present outside the operating band (OOB blocking) or inside the operating band (in-band blocking), but not adjacent to the desired signal. The in-band blocking characteristics is a measure of the receiver's ability to receive a desired signal in its assigned channel at the antenna connector for BS Type 1-C or TAB connector for BS Type 1-H in the presence of an unwanted interferer, which is an NR signal for general blocking or an NR signal with one resource block for narrowband blocking (see Fig. 5.10). In-band blocking includes interferers within 20-60
