The WTRU may determine a channel uncertainty and determine, based on a comparison of the channel uncertainty to at least one threshold value, a combination of a set of SL TCIs and a HARQ configuration to use for communicating via a sidelink feedback channel. The WTRU may send a transmission, via a sidelink feedback channel, using the determined set of SL TCIs and using the determined HARQ configuration.

Abstract: Methods and apparatuses are described herein to address issues at the MAC layer resulting from potential Listen-Before-Talk (LBT) failures and delayed transmission. For example, a wireless transmit/receive unit (WTRU) may monitor a plurality of TX resource pools within a sidelink bandwidth part (BWP) for LBT events. The WTRU may cause, based on determining that an LBT failure has occurred, a corrective action associated with a sidelink MAC procedure. The WTRU may determine, based on the LBT failure, that a total number or consecutive number of detected LBT failures for one of the monitored TX resource pools exceeds a threshold, indicating a consistent LBT failure. The WTRU may, based on the consistent LBT failure, send an indication of the consistent LBT failure for the TX resource pool to peer WTRUs, and an indication of the consistent LBT failure for the TX resource pool to a serving cell.
