1. A user equipment, comprising:
a processor; and
a memory in electronic communication with the processor, wherein instructions stored in the memory are executable to:
monitor a physical sidelink control channel (PSCCH) for first sidelink control information (SCI) when a first timer is running, and
for the received first SCI,
in a case that HARQ feedback is enabled by the first SCI,
start a second timer upon an end of a physical sidelink feedback channel (PSFCH) transmission for the HARQ feedback,
start a third timer after an expiry of the second timer, and
monitor the PSCCH for second SCI when the third timer is running, and
in a case that the HARQ feedback is disabled by the first SCI,
start a fourth timer upon an end of a physical sidelink shared channel (PSSCH) transmission indicated in the first SCI,
start a fifth timer after an expiry of the fourth timer, and
monitor the PSCCH for the second SCI when the fifth timer is running.
