Detailed Description

For a more complete understanding of the nature and the technical content of the embodiments of the present application, reference should be made to the following detailed description of embodiments of the present application in connection with the accompanying drawings, which are provided for purposes of illustration only and are not intended to limit the embodiments of the present application.

Before describing the retransmission method provided in the embodiments of the present application in detail, a brief description of random access in the related art will be provided.

In Rel-15 NR, in order to improve transmission reliability, edge transmission is guaranteed, and repetition transmission is introduced. For Dynamic resources (DG), use a pusch-aggregation factor; for the Configured resource (CG), the repetition number (repK) is Configured. For a first transmission (new transmission) of a cluster of resources, a media access control (Media Access Control, MAC) protocol data unit (Protocol Data Unit, PDU) needs to be generated, and the retransmission transmission after the first transmission is considered as retransmission. Each transmission in Bundle is considered a separate Uplink resource (Uplink grant) and uses the same HARQ process as the first repetition. Here, a resource bundle is a set of a plurality of resources, and thus, the resource bundle is also referred to as a resource set or a resource group.

For the repetition transmission described above, it can be described as follows:

When the MAC entity is configured with pusch-AggregationFactor＞1，the parameter pusch-AggregationFactor provides the number of transmissions of a TB within a bundle of the dynamic grant.After the initial transmission，pusch-AggregationFactor-1 HARQ retransmissions follow within a bundle.When the MAC entity is configured with repK＞1，the parameter repK provides the number of transmissions of a TB within a bundle of the configured uplink grant.After the initial transmission，HARQ retransmissions follow within a bundle.For both dynamic grant and configured uplink grant，bundling operation relies on the HARQ entity for invoking the same HARQ process for each transmission that is part of the same bundle.Within a bundle，HARQ retransmissions are triggered without waiting for feedback from previous transmission according to pusch-AggregationFactor for a dynamic grant and repK for a configured uplink grant，respectively.Each transmission within a bundle is a separate uplink grant after the initial uplink grant within a bundle is delivered to the HARQ entity.

for newly transmitted resource processing, if the resource is CG grant or the resource is DG grant but the HARQ process corresponds to the HARQ process of CG grant; it is necessary to start the configuration grant timer (configured grant Timer) or to restart the configuration grant timer at the same time.

For the processing of retransmitted resources, the resources are not the first repetition of the bundle and collide with the dynamically scheduled grant or the grant of the random access response (Random Access Response, RAR), and the resources are ignored; otherwise, the resource is utilized for retransmission.

The resource handling procedure for new transmissions and the resource handling procedure for retransmissions are as follows:

For each uplink grant，the HARQ entity shall：

1>identify the HARQ process associated with this grant，and for each identified HARQ process：

2>if the received grant was not addressed to a Temporary C-RNTI on PDCCH，and the NDI provided in the associated HARQ information has been toggled compared to the value in the previous transmission of this TB of this HARQ process；or

2>if the uplink grant was received on PDCCH for the C-RNTI and the HARQ buffer of the identified process is empty；or

2>if the uplink grant was received in a Random Access Response；or

2>if the uplink grant was received on PDCCH for the C-RNTI in ra-ResponseWindow and this PDCCH successfully completed the Random Access procedure initiated for beam failure recovery；or

2>if the uplink grant is part of a bundle of the configured uplink grant，and may be used for initial transmission according to clause 6.1.2.3 of TS 38.214[7]，and if no MAC PDU has been obtained for this bundle：

3>if there is a MAC PDU in the Msg3 buffer and the uplink grant was received in a Random Access Response；or：

3>if there is a MAC PDU in the Msg3 buffer and the uplink grant was received on PDCCH for the C-RNTI in ra-ResponseWindow and this PDCCH successfully completed the Random Access procedure initiated for beam failure recovery：

4>obtain the MAC PDU to transmit from the Msg3 buffer.

4>if the uplink grant size does not match with size of the obtained MAC PDU；and

4>if the Random Access procedure was successfully completed upon receiving the uplink grant：

5>indicate to the Multiplexing and assembly entity to include MAC subPDU(s)carrying MAC SDU from the obtained MAC PDU in the subsequent uplink transmission；

5>obtain the MAC PDU to transmit from the Multiplexing and assembly entity.

3>else：

4>obtain the MAC PDU to transmit from the Multiplexing and assembly entity，if any；

3>if a MAC PDU to transmit has been obtained：

4>deliver the MAC PDU and the uplink grant and the HARQ information of the TB to the identified HARQ process；

4>instruct the identified HARQ process to trigger a new transmission；

4>if the uplink grant is addressed to CS-RNTI；or

4>if the uplink grant is a configured uplink grant；or

4>if the uplink grant is addressed to C-RNTI，and the identified HARQ process is configured for a configured uplink grant：

5>start or restart the configuredGrantTimer，if configured，for the corresponding HARQ process when the transmission is performed.

3>else：

4>flush the HARQ buffer of the identified HARQ process.

2>else(i.e.retransmission)：

3>if the uplink grant received on PDCCH was addressed to CS-RNTI and if the HARQ buffer of the identified process is empty；or

3>if the uplink grant is part of a bundle and if no MAC PDU has been obtained for this bundle；or

3>if the uplink grant is part of a bundle of the configured uplink grant，and the PUSCH duration of the uplink grant overlaps with a PUSCH duration of another uplink grant received on the PDCCH or in a Random Access Response for this Serving Cell：

4>ignore the uplink grant.

3>else：

4>deliver the uplink grant and the HARQ information(redundancy version)of the TB to the identified HARQ process；

4>instruct the identified HARQ process to trigger a retransmission；

4>if the uplink grant is addressed to CS-RNTI；or

in step S200, the network device schedules a new transmission or retransmission of HARQ.

And the terminal equipment utilizes the resource bundle to carry out new transmission or retransmission of HARQ according to the scheduling of the network equipment.
