Abstract

A method for enhanced physical uplink shared channel (PUSCH) repetitions includes receiving at least one of a dynamic grant or a configured grant for an uplink transmission, determining a time domain resource allocation (TDRA) for repeated transmission of the uplink transmission on a PUSCH, and repeatedly transmitting the uplink transmission based on the TDRA.

Claims (39)

1 . A method, comprising:

receiving a grant for an uplink transmission on a physical uplink shared channel (PUSCH);

receiving an indication of an entry in a time domain resource allocation (TDRA) table associated with the uplink transmission on the PUSCH, wherein the entry in the TDRA table indicates a number of repetitions; and

transmitting the uplink transmission according to the number of repetitions.

2 . The method of claim 1 , further comprising determining the TDRA table associated with the uplink transmission on the PUSCH.

3 . The method of claim 1 , wherein the indication of the entry in the TDRA table is included in at least one of a downlink control information (DCI) message or a radio resource control (RRC) message.

4 . The method of claim 3 , wherein the at least one of the DCI message or the RRC message comprises the grant for the uplink transmission on the PUSCH.

5 . The method of claim 1 , wherein the entry in the TDRA table comprises a start and length indicator value (SLIV).

6 . The method of claim 1 , wherein the uplink transmission is repeated once per slot according to the number of repetitions.

7 . The method of claim 1 , wherein the uplink transmission is repeated with a periodicity of less than a slot according to the number of repetitions.

8 . The method of claim 1 , further comprising:

determining that the uplink transmission and at least one other PUSCH transmission are pending transmission;

determining that the at least one other PUSCH transmission has a higher priority relative to the uplink transmission; and

dropping at least one repetition of the uplink transmission that overlaps with the at least one PUSCH transmission having the higher priority.

9 . The method of claim 1 , further comprising ignoring a PUSCH aggregation factor.

10 . The method of claim 1 , wherein the method is performed by a user equipment (UE) or one or more baseband processors.

11 . An apparatus comprising:

one or more processors; and

a memory storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:

receiving a grant for an uplink transmission on a physical uplink shared channel (PUSCH);

receiving an indication of an entry in a time domain resource allocation (TDRA) table associated with the uplink transmission on the PUSCH, wherein the entry in the TDRA table indicates a number of repetitions; and

transmitting the uplink transmission according to the number of repetitions.

12 . The apparatus of claim 11 , the memory storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:

determining the TDRA table associated with the uplink transmission on the PUSCH.

13 . The apparatus of claim 11 , wherein the indication of the entry in the TDRA table is included in at least one of a downlink control information (DCI) message or a radio resource control (RRC) message.

14 . The apparatus of claim 11 , wherein the uplink transmission is repeated once per slot according to the number of repetitions, or wherein the uplink transmission is repeated with a periodicity of less than a slot according to the number of repetitions.

15 . The apparatus of claim 11 , wherein the apparatus is a user equipment (UE) or one or more baseband processors.

16 . A method, comprising:

transmitting, to a user equipment (UE), a grant for an uplink transmission on a physical uplink shared channel (PUSCH);

transmitting, to the UE, an indication of an entry in a time domain resource allocation (TDRA) table associated with the PUSCH, wherein the entry in the TDRA table indicates a number of repetitions; and

receiving, from the UE, repetitions of the uplink transmission based on the number of repetitions.

17 . The method of claim 16 , further comprising:

signaling, to the UE, the TDRA table associated with the uplink transmission on the PUSCH.

18 . The method of claim 16 , wherein the indication of the entry in the TDRA table is included in at least one of a downlink control information (DCI) message or a radio resource control (RRC) message.

19 . The method of claim 18 , wherein the at least one of the DCI message or the RRC message comprises the grant for the uplink transmission on the PUSCH.

20 . The method of claim 16 , further comprising:

determining that the uplink transmission and at least one other PUSCH transmission are pending transmission;

determining that the at least one other PUSCH transmission has a higher priority relative to the uplink transmission; and

determining that repetitions of the uplink transmission that overlap with the at least one PUSCH transmission having the higher priority will be dropped.
