1. A method, comprising:
transmitting, by a first user equipment (UE) to a second UE, a sidelink control information (SCI) in a sidelink burst during a channel occupancy (CO) initiated by the first UE in one or more channels of a shared spectrum, the SCI comprising CO time (COT) sharing information, the COT sharing information indicating:
a duration within the CO initiated by the first UE available for a sidelink transmission opportunity by the second UE within the one or more channels after a time slot in which the SCI has been transmitted by the first UE, and
a channel access priority class (CAPC) value used by the first UE to initiate the CO; and
receiving, by the first UE from the second UE, a sidelink transmission within the sidelink transmission opportunity and in accordance with the COT sharing information in the SCI,
wherein a first listen-before talk (LBT) procedure by the second UE before the sidelink transmission by the second UE is within a first switching gap within the CO, wherein the first switching gap is between the sidelink burst and the sidelink transmission by the second UE, and wherein the first LBT procedure by the second UE is a Type 2 LBT procedure.
