1. A method of wireless communication performed by a first sidelink user equipment (UE), the method comprising:
receiving, from a base station (BS), a resource pool (RP) configuration that indicates resources in a licensed frequency band reserved for sidelink control information (SCI);
receiving a second SCI indicating a starting position of channel occupancy time (COT) resources in an unlicensed frequency band;
transmitting, to a second sidelink UE, the SCI in the reserved resources, wherein the SCI includes the starting position of the COT resources in the unlicensed frequency band; and
transmitting, to the second sidelink UE, a physical sidelink shared channel (PSSCH) via the COT resources in the unlicensed frequency band,
wherein the transmitting the PSSCH comprises transmitting the PSSCH in the starting position of the COT resources indicated in the second SCI based on at least one of:
a reference signal received power (RSRP) satisfying a threshold; or
an amount of resources reserved in the unlicensed frequency band.
