Methods and apparatuses for handling conflict between sidelink data transmission and uplink small data transmission

A user equipment (UE), comprising:

• one or more non-transitory computer-readable media storing computer-executable instructions;
• and
• at least one processor coupled to the one or more non-transitory computer-readable media, and configured to execute the computer-executable instructions to:
• initiate a Small Data Transmission (SDT) procedure for transmitting a first set of data packets to a base station (BS) via an uplink (UL) transmission;
• and
• determine, while the UE is in a Radio Resource Control (RRC) Inactive state, whether to prioritize the UL transmission over a sidelink (SL) transmission when there is a conflict between the UL transmission and the SL transmission during the SDT procedure,
• wherein the SL transmission is for transmitting a second set of data packets to another UE.
