Methods and apparatuses for a transmit wtru to identify a synchronization wtru and request s-ssb transmission on one or more rb sets

Abstract

A wireless transmit/receive unit (WTRU) may include a processor, memory, and/or a transceiver. The WTRU may be configured to monitor sidelink synchronization signal block (S-SSB) transmissions within a configured frequency range. The WTRU may determine identification information associated with a synchronization reference WTRU based on the S-SSB transmissions. The WTRU may initiate a channel occupancy time (COT) on one or more resource block (RB) sets using listen before talk (LBT) to transmit a sidelink transmission. The WTRU may determine an overlap between the COT and S-SSB slots, and determine additional required sidelink transmissions after the S-SSB slots. The WTRU may determine the one or more RB sets to be used for sidelink transmission after S-SSB slots. The WTRU may transmit a request for the synchronization reference WTRU to transmit S-SSB on the determined one or more RB sets.
