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.
