Test Procedure
The MS is triggered to initiate packet uplink transfer in RLC acknowledged mode, and with Extended Dynamic Allocation MAC mode. The SS orders the MS to use two-phase access procedure. The maximum number of UL timeslots is assigned, according to the mobile multislot class (TS 45.002 Annex B.1).
For one block period, the SS allocates blocks on all but the two lowest-numbered assigned PDCHs, by signalling to the MS the USF assigned to the third PDTCH using the third PDCH. It is checked that the MS sends RLC data blocks on all but the two lowest-numbered assigned PDTCHs.
For the next block period, the SS increases the number of PDCHs allocated to the MS, and allocates blocks on all but the lowest PDCH, by signalling to the MS the USF assigned to the second PDTCH using the second PDCH. It is checked that the MS sends RLC data blocks on all but the lowest-numbered assigned PDTCH.
For the next block period, the SS increases the number of PDCHs again, and allocates blocks on all assigned PDCHs, by signalling to the MS the USF assigned to the first PDTCH, but using the second PDCH. It is checked that the MS sends RLC data blocks on all PDTCHs.
The MS completes the packet data transfer.

1. If a PACKET PDCH RELEASE message releases the second PDCH in the current timeslot configuration of a mobile station using Shifted USF operation then the first timeslot shall be considered released. If any PDCHs remain in the new timeslot configuration then normal USF operation shall continue starting on the lowest available timeslot.
2. If the current timeslot configuration requires Shifted USF operation (see sub-clause 8.1.1.2.4) and the PACKET PDCH RELEASE message modifies the configuration in such a way that Shifted USF operation is no longer required then normal USF operation shall apply after a suitable reaction time as defined in 3GPP TS 45.010.
3. Upon a receipt of a commanding message or indication from the network requiring an action by the mobile station, if the reaction time for such action is not specified elsewhere, the mobile station shall begin to perform the required action no later than the next occurrence of block B((x+6) mod 12), where block B(x) is the radio block containing the commanding message or indication form the network.

The MS is triggered to initiate packet uplink transfer in RLC acknowledged mode. The SS orders the MS to use two-phase access procedure. The maximum number of UL timeslots is assigned, according to the mobile multislot class (TS 45.002 Annex B.1).
The SS signals to the MS the USF assigned to the lowest PDTCH on the second PDCH, and, in the next block period, it is checked that the MS sends RLC/MAC data blocks on all assigned PDTCH.
The SS sends a PACKET PDCH RELEASE message with TIMESLOTS_AVAILABLE indicating that the second lowest assigned PDCH timeslots is not available for packet data. For that block period, and the next five block periods, the SS continues signals to the MS the USF assigned to the lowest PDTCH on the second PDCH, and also the USF assigned to the third PDTCH on the corresponding PACCH.
On the sixth block period following the PACKET PDCH RELEASE message, it is checked that the MS has stopped transmitting on the two lowest timeslots, but continues to transmit on the remaining timeslots.
The SS completes the data transfer using the remaining timeslots.

The establishment of an EC Temporary Block Flow (EC TBF), for a mobile station that has enabled EC operation, is performed on the EC-CCCH. It can be initiated by either the mobile station or the network. The establishment of an EC TBF can also be performed on the CCCH if the mobile station has selected Coverage Class 1 in both the uplink and downlink directions, see 3GPP TS 45.008 and 3GPP TS 44.018.
...
When the mobile station receives a Fixed Uplink Allocation, FUA, in e.g. the EC PACKET UPLINK ASSIGNMENT or EC PACKET UPLINK ACK/NACK message it shall perform uplink transmissions according to that allocation.
...
This message may be sent by an EC capable mobile station attempting system access using the EC-RACH (see sub-clause 3.5.2.1.2a) in which the message format is as shown in Tables 9.1.65.1 and 9.1.65.2. This message can also be sent using the RACH (see sub-clause 3.5.2.1.2) in which the message format is as shown in Tables 9.1.65.3 and 9.1.65.4.
...
In case overlaid CDMA is used, see 3GPP TS 43.064 [6], up to four MS can be multiplexed on the same physical resource, simultaneously transmitting, using different orthogonal codes assigned by the network, see 3GPP TS 44.060 [11]. The codes are applied per burst over the assigned PDCHs for EC-PDTCH and EC-PACCH in each TDMA frame from the lowest to the highest numbered assigned TN, according to Table 6.3-2, and are only applied in case blind physical layer transmissions are used (i.e. for CC2, CC3 and CC4).
...
When EC operation is enabled the packet uplink resource is assigned to the mobile station in an EC IMMEDIATE ASSIGNMENT TYPE 1 message sent in unacknowledged mode on the same CCCH timeslot on which the network received the EC PACKET CHANNEL REQUEST message (see Table 3.5.2.1.2.3). Timer T3141 is started on the network side.

When the mobile station receives a Fixed Uplink Allocation, FUA, in e.g. the EC PACKET UPLINK ASSIGNMENT or EC PACKET UPLINK ACK/NACK message it shall perform uplink transmissions according to that allocation. The uplink resources are allocated with respect to a BTTI configuration, the mobile station uplink coverage class, the assigned MCS, the number of RLC data blocks required for the EC TBF as indicated by the mobile station and with respect to the latest ack/nack status as perceived by the network, if such exists, and transmitted to the mobile station in the message containing the FUA. The uplink resources will be allocated according to the coverage class dependent resource mapping (see 3GPP TS 45.002) and the mobile station shall transmit accordingly.
...
When the mobile station has an ongoing downlink EC TBF, it may initiate an uplink EC TBF by including the EC Channel Request Description information element in the EC PACKET DOWNLINK ACK/NACK message on the EC-PACCH and start timer T3168. The network may then establish an uplink EC TBF by sending an EC PACKET UPLINK ASSIGNMENT message to the mobile station, in which case the downlink EC TBF is released.
...
In EC operation, the downlink EC TBF is released at establishment of the uplink EC TBF.
...
In case overlaid CDMA is used, see 3GPP TS 43.064 [6], up to four MS can be multiplexed on the same physical resource, simultaneously transmitting, using different orthogonal codes assigned by the network, see 3GPP TS 44.060 [11].

STARTING_DL_TIMESLOT_OFFSET (2 bit field)
This field defines the timeslot number of the lowest timeslot included in the assignment that is used for transfer of downlink RLC/MAC control messages on the EC-PACCH during the UL EC TBF. The number of additional timeslots that are included in the downlink assignment depends on the assigned DL Coverage Class. The assigned timeslots are contiguous, starting with the timeslot number indicated in the STARTING_DL_TIMESLOT_OFFSET field. The STARTING_DL_TIMESLOT_OFFSET field is encoded as an offset to the timeslot assigned with the STARTING_UL_TIMESLOT field. The encoding of the field is dependent of the value of the UL_COVERAGE_CLASS and DL_COVERAGE_CLASS fields in the same message.

The mobile station in EC TBF mode may include an EC Channel Request Description in the EC PACKET DOWNLINK ACK/NACK message in order to request an uplink TBF. The network may then establish an uplink EC TBF for the mobile station by sending an EC PACKET UPLINK ASSIGNMENT message, in which case the downlink EC TBF is released.
…
TIMESLOT_MULTIPLICATOR (3 bit field)
This field defines how many UL timeslots that the assignment contains when the assigned UL Coverage Class, according to the UL_COVERAGE_CLASS field, is CC1.
…
Values other than ‘000’ can only be used if supported by the mobile station, as indicated by its multislot capability, see 3GPP TS 45.002. If the assigned uplink Coverage Class > CC1 (according to the UL_COVERAGE_CLASS field), the mobile station shall consider the TIMESLOT_MULTIPLICATOR field as not valid
START_FIRST_UL_RLC_DATA_BLOCK (4 bit field)
This field indicates the starting position of the resources for the first allocated RLC Data block in the fixed uplink allocation. The starting position is relative to the first TDMA frame (N) of the downlink block containing the last blind physical layer transmission of this EC PACKET UPLINK ASSIGNMENT message, according to the USED_DL_COVERAGE_CLASS field. The encoding of the field is dependent of the value of the UL_COVERAGE_CLASS and the TIMESLOT_MULTIPLICATOR fields in the same message.
…
DELAY_NEXT_UL_RLC_DATA_BLOCK (3 bit field)
This field indicates the position of the next allocated RLC Data block in the fixed uplink allocation. The position is calculated as the number of transmission opportunities from the previous uplink allocation, according to the UL_COVERAGE_CLASS and TIMESLOT_MULTIPLICATOR fields in the same assignment message, where the next uplink allocation for the mobile station is placed and where the mobile station thus shall transmit the next RLC data block. In the transmission opportunity/ies between the previous uplink allocation and this allocation the mobile station is not allocated any resource, and shall thus not transmit.

When timer T3226 expires, the mobile station shall monitor the EC-PACCH according to its assigned downlink coverage class and, as long as T3228 is running, attempt to decode every downlink RLC/MAC block on the PDCHs corresponding to the downlink assigned EC-PACCH resources.
Whenever the mobile station receives an RLC/MAC block containing an RLC/MAC control block, the mobile station shall attempt to interpret the message contained therein. If the message addresses the mobile station, the mobile station shall act on the message.
If timer T3228 expires, the mobile station shall release the ongoing uplink TBF and may perform an abnormal release with access retry, unless timer T3248 (sent in EC-SI) is used. If T3248 is used, i.e. it has a value > 0, the mobile station shall instead start timer T3248 and continue to monitor the DL EC-PACCH using the next higher DL Coverage Class, if such exists. If no higher DL CC than the assigned DL CC exists, the mobile station shall continue to monitor the DL EC-PACCH for reception of an EC PACKET UPLINK ACK/NACK message or an EC PACKET UPLINK ACK/NACK AND CONTENTION RESOLUTION message according to the last assigned DL CC until T3248 expires.
The assigned resources (timeslots) to be used for the downlink EC-PACCH according to the next higher DL Coverage Class are either the same as the assigned timeslots for the uplink EC-PDTCH or given in the assignment message. If no valid resources for the next higher Coverage Class are assigned, the mobile station shall continue to monitor the downlink EC-PACCH using the assigned DL Coverage Class while timer T3248 is running.
When the mobile station receives an EC PACKET UPLINK ACK/NACK message or an EC PACKET UPLINK ACK/NACK AND CONTENTION RESOLUTION message addressing the mobile station with the TFI value associated with its uplink TBF it shall stop T3228, if running. If timer T3248 was running at reception of the EC PACKET UPLINK ACK/NACK message or the EC PACKET UPLINK ACK/NACK AND CONTENTION RESOLUTION message (and thus not T3228), the timer T3248 shall be stopped.

The purpose of network initiated TBF establishment is to establish a TBF to support the transfer of upper layer PDUs in the direction from the network to the mobile station. The procedure is triggered by a request from upper layers on the network side to transfer an upper layer PDU to a mobile station in packet idle mode that has enabled EC operation. Upon such a request, the network shall initiate a packet downlink assignment procedure on the EC-CCCH as described in 3GPP TS 44.018.
...
For a TBF in BTTI configuration, prior to the initiation of RLC data block transfer on the downlink, the network assigns the following parameters in a downlink assignment.
in case of a downlink EC TBF, the network also assigns the following parameters:
- uplink and downlink coverage classes;
- a set of PDCHs to be used for transmission of uplink RLC/MAC control messages.
...
If the mobile station, in the EC PACKET UPLINK ACK/NACK message with the Final Ack Indicator bit set to '1’, has been indicated to continue monitoring the EC-PACCH, it shall start timer T3238. The mobile station shall then monitor the EC-PACCH, according to its assigned downlink Coverage Class of the TBF, after an initial waiting time as indicated in the EC PACKET UPLINK ACK/NACK message. The mobile station shall then monitor the EC-PACCH, using a monitoring pattern as indicated in the EC PACKET UPLINK ACK/NACK message, until timer T3238 expires or until a downlink RLC/MAC control message triggering the release of the TBF is received. When timer T3238 expires, the mobile station shall leave the TBF and return to packet idle mode.
...
If the mobile station receives an EC PACKET DOWNLINK ASSIGNMENT message addressing the mobile station while listening to the EC-PACCH, it shall stop timer T3238, release the uplink TBF and act on the assigned resources.
...
An uplink EC TBF is released when the network has received all RLC data blocks for a TBF, as indicated by the mobile station, and sent the EC PACKET UPLINK ACK/NACK message with the Final Ack Indicator bit set to '1'. An exception is when the mobile station, in the EC PACKET UPLINK ACK/NACK message with the Final Ack Indicator bit set to '1', is ordered to continue monitoring the EC-PACCH, see sub-clause 9.3.2.4.3

42.10.3.1 EC-GSM-IoT / Contention resolution / Enhanced Access Burst procedure

The contention resolution is completed on the mobile station side when the mobile station receives a PACKET UPLINK ASSIGNMENT message with the same TLLI as the mobile station has included in the PACKET RESOURCE REQUEST message.

|
The TLLI is used to uniquely identify the mobile station when sending on the uplink. A mobile station, that has enabled EC operation, includes its TLLI in one or several of the uplink blocks that are transmitted during the establishment of an EC TBF, depending on what packet access procedure is used.
The contention resolution is described for the different packet access procedures in the following sub-clauses:
- using Access Burst procedure, with inclusion of the full TLLI in each RLC data block that is sent on the TBF until contention resolution is completed, described in 7a.2.1.1;
- using Enhanced Access Burst procedure, with inclusion of the full TLLI in only the first RLC data block that is sent on the TBF and then inclusion of a limited part of the TLLI in the subsequent RLC data blocks that are sent until contention resolution is completed, described in 7a.2.1.2.
The network indicates in the EC Immediate Assignment message which of the procedures that shall be used for the contention resolution, see 3GPP TS 44.018.
…
When the Enhanced Access Burst procedure is used, only the first RLC data block that is sent on the TBF shall include the TLLI of the mobile station. If MCS-7, MCS-8 or MCS-9 is used for the transmission of the TLLI (i.e. the RLC/MAC block is carrying two RLC data blocks), the TLLI shall be inserted in both RLC data blocks that are included in the first RLC/MAC block. Every RLC data block that is sent on the TBF, except the first one, shall include the reduced TLLI (rTLLI) of the mobile station until the mobile station receives an EC PACKET UPLINK ACK/NACK AND CONTENTION RESOLUTION message or an EC PACKET UPLINK ACK/NACK message addressing the mobile station with the TFI value associated with the uplink TBF and containing either the TLLI or the rTLLI of the mobile station. The reduced TLLI (rTLLI) consists of the 4 least significant bits of the TLLI of the mobile station. The rTLLI shall not be included in the RLC/MAC header if the TLLI is included in the RLC Data block. The rTLLI value shall thus not be included in the RLC/MAC header of the first RLC Data block of a TBF, with BSN=0 and, if MCS-7, MCS-8 or MCS-9 is used for the transmission, with BSN=1, since the TLLI of the mobile station is included in the RLC data block(s).
If the failure is due to a TLLI mismatch, or to the expiry of timers T3166 or T3168, or to the fact that the counter N3104 reached its maximum value in the contention resolution procedure, and repetition as described in subclause 7.1.3.3 has been performed, the mobile station shall remain in packet idle mode, notify higher layer (TBF establishment failure), transactions in progress shall be aborted and cell reselection continued.

Test Procedure
SS establishes a downlink TBF and sends RLC data blocks with BSN values between 0 to N in sequence. The MS is polled in each RLC data block by setting the S/P bit. SS verifies that the SSN in the Packet Downlink Ack/Nack messages sent by the MS are set to [BSN+1] modulo 128. SS then sends RLC data block with random BSN N1 that holds a value between [N+1] modulo 128 and [N+64] modulo 128. The MS is polled in the last RLC data block by setting the S/P bit. SS verifies that the SSN in the Packet Downlink Ack/Nack message sent by the MS is set to [N1+1] modulo 128.
The test is performed for the values of N = 1, 10, 63, 64, 126, 127.

1. The Extension (E) bit is used to indicate the presence of an optional extension octet in the RLC data block header. The More (M) bit is used to indicate the presence of an LLC frame following the current LLC frame. The M bit, the E bit, and the Length Indicator, are used to delimit LLC frames within a TBF.
2. The Length Indicator (LI) field is six bits in length and shall be encoded as a binary number. The value 0 shall indicate that no LLC frame boundary does exist, that the M bit shall be ignored and that the E bit shall be interpreted as having the value 1.
3 A singular case occurs when the end of the LLC PDU would fit within the RLC data block but the addition of the Length Indicator octet (to indicate the LLC PDU boundary) causes the LLC PDU to extend into the next RLC data block. In this case, this additional LI field shall take the value 0 whatever is the length of the last but one LLC PDU segment.
