13. A method performed by a wireless transmit/receive unit (WTRU), comprising:
receiving configuration information associated with a sidelink (SL) listen before talk (LBT) procedure, wherein the configuration information indicates a time period and a maximum counter value;
performing, based on the configuration information, the SL LBT procedure;
determining to trigger a consistent SL LBT failure (CSLF) associated with a set of resources of a resource pool, wherein the determination to trigger the CSLF is based on the SL LBT procedure, and wherein a number of LBT failures associated with the set of resources of the resource pool reaches the maximum counter value;
based on the determination to trigger the CSLF, starting a timer, wherein the timer is associated with the time period:
during the time period that the timer is running, selecting a first resource for a first SL transmission, wherein the first resource is selected from the resource pool excluding the set of resources associated with the CSLF;
triggering a CSLF medium access control (MAC) control element (CE);
sending the CSLF MAC CE; and
after the timer expires, cancelling the CSLF associated with the set of resources.
