LITE SL-SS (SIDELINK SYNCHRONIZATION SIGNAL) TRANSMISSION FOR ON DEMAND S-SSB (SIDELINK SYNCHRONIZATION SIGNAL BLOCK)

Abstract:

A method of wireless communications by a transmitting sidelink user equipment (UE) includes transmitting a sidelink synchronization signal (SL-SS) within a sidelink synchronization signal block (S-SSB). The SL-SS has an SL-SS pattern with a reduced number of physical sidelink broadcast channel (PSBCH) symbols, which may be zero PSBCH symbols. The method also includes receiving transmission in accordance with the SL-SS. The SL-SS may be transmitted at a time and/or frequency different from a legacy SL-SS.
