Abstract

Claims (48)

1. A method performed by a User Equipment (UE) for Hybrid Automatic Repeat Request (HARQ) process Identity (ID) selection, the method comprising:

receiving a configuration message to configure a Configured Grant (CG) configuration and a set of HARQ process IDs that is available for the CG configuration, the set of HARQ process IDs including a first HARQ process ID and a second HARQ process ID;

determining a CG physical uplink shared channel (PUSCH) corresponding to the CG configuration;

selecting, based on a first HARQ process ID selection procedure, the first HARQ process ID or the second HARQ process ID for the CG PUSCH in a case that a Logical Channel (LCH)-based prioritization indication, a CG retransmission timer, and an Information Element (IE) for enabling the first HARQ process ID selection procedure are configured; and

transmitting, based on the selected first or second HARQ process ID, a first Medium Access Control (MAC) Protocol Data Unit (PDU) for retransmission or a second MAC PDU for initial transmission on the CG PUSCH, wherein the first HARQ process ID selection procedure includes:

determining a priority of first data multiplexed in the first MAC PDU as a first priority of the first HARQ process ID;

determining a priority of second data to be multiplexed in the second MAC PDU as a second priority of the second HARQ process ID;

selecting, based on the first priority and the second priority, the first HARQ process ID or the second HARQ process ID for the CG PUSCH; and

prioritizing the first HARQ process ID over the second HARQ process ID in a case that the first priority is equal to the second priority.

2. The method of claim 1 , wherein:

the first data is from a first set of LCHs,

the second data is from a second set of LCHs,

the priority of the first data is determined based on an LCH with a highest LCH priority among the first set of LCHs, and

the priority of the second data is determined based on an LCH with a highest LCH priority among the second set of LCHs.

3. The method of claim 1 , wherein the first HARQ process ID selection procedure further includes:

selecting the first HARQ process ID for the CG PUSCH in a case that the first priority is higher than the second priority; and

selecting the second HARQ process ID for the CG PUSCH in a case that the second priority is higher than the first priority.

4. The method of claim 1 , wherein the IE is configured for the CG configuration or for a MAC entity of the UE.

5. The method of claim 1 , further comprising:

selecting, based on a second HARQ process ID selection procedure, the first HARQ process ID or the second HARQ process ID for the CG PUSCH in a case that at least one of the LCH-based prioritization indication, the CG retransmission timer, and the IE is not configured, wherein the second HARQ process ID selection procedure includes:

prioritizing the first HARQ process ID over the second HARQ process ID.

6. The method of claim 5 , wherein prioritizing the first HARQ process ID over the second HARQ process ID comprises:

selecting the first HARQ process ID for the CG PUSCH.

7. A User Equipment (UE) for Hybrid Automatic Repeat Request (HARQ) process Identity (ID) selection, the UE comprising:

at least one processor; and

at least one non-transitory computer-readable medium coupled to the at least one processor and storing one or more computer-executable instructions that, when executed by the at least one processor, cause the UE to:

receive a configuration message to configure a Configured Grant (CG) configuration and a set of HARQ process IDs that is available for the CG configuration, the set of HARQ process IDs including a first HARQ process ID and a second HARQ process ID;

determine a CG physical uplink shared channel (PUSCH) corresponding to the CG configuration;

select, based on a first HARQ process ID selection procedure, the first HARQ process ID or the second HARQ process ID for the CG PUSCH in a case that a Logical Channel (LCH)-based prioritization indication, a CG retransmission timer, and an Information Element (IE) for enabling the first HARQ process ID selection procedure are configured; and

transmit, based on the selected first or second HARQ process ID, a first Medium Access Control (MAC) Protocol Data Unit (PDU) for retransmission or a second MAC PDU for initial transmission on the CG PUSCH, wherein the first HARQ process ID selection procedure includes:

determining a priority of first data multiplexed in the first MAC PDU as a first priority of the first HARQ process ID;

determining a priority of second data to be multiplexed in the second MAC PDU as a second priority of the second HARQ process ID;

selecting, based on the first priority and the second priority, the first HARQ process ID or the second HARQ process ID for the CG PUSCH; and

prioritizing the first HARQ process ID over the second HARQ process ID in a case that the first priority is equal to the second priority.

8. The UE of claim 7 , wherein:

the first data is from a first set of LCHs,

the second data is from a second set of LCHs,

the priority of the first data is determined based on an LCH with a highest LCH priority among the first set of LCHs, and

the priority of the second data is determined based on an LCH with a highest LCH priority among the second set of LCHs.

9. The UE of claim 7 , wherein the first HARQ process ID selection procedure further includes:

selecting the first HARQ process ID for the CG PUSCH from the set of HARQ process IDs in a case that the first priority is higher than the second priority; and

selecting the second HARQ process ID for the CG PUSCH in a case that the second priority is higher than the first priority.

10. The UE of claim 7 , wherein the IE is configured for the CG configuration or for a MAC entity of the UE.

11. The UE of claim 7 , wherein the one or more computer-executable instructions, when executed by the at least one processor, further cause the UE to:

select, based on a second HARQ process ID selection procedure, the first HARQ process ID or the second HARQ process ID for the CG PUSCH in a case that at least one of the LCH-based prioritization indication, the CG retransmission timer, and the IE is not configured, wherein the second HARQ process ID selection procedure includes:

prioritizing the first HARQ process ID over the second HARQ process ID.

12. The UE of claim 11 , wherein prioritizing the first HARQ process ID over the second HARQ process ID comprises:

selecting the first HARQ process ID for the CG PUSCH.
