1. A user equipment (UE) comprising:
radio frequency (RF) circuitry;
a memory; and
processing circuitry coupled to the memory and configured to execute instructions stored in the memory to cause the UE to:
receive a physical downlink control channel (PDCCH) to activate a sidelink configured grant for a sidelink communication;
derive a hybrid automatic repeat request (HARQ) process identifier (ID) for the sidelink configured grant based on a current slot variable that is a function of a system frame number (SFN);
transmit, via the RF circuitry, the sidelink communication based on the HARQ process ID;
receive downlink control information (DCI) with DCI format 3_0 including a frequency resource assignment (FRA) field; and
in response to the FRA field of the DCI being set to all ones, processing a release operation for the sidelink configured grant.
