METHOD AND APPARATUS FOR COVERAGE ENHANCEMENT OF SIDELINK SYNCHRONIZATION SIGNAL BLOCK

Abstract: systems and methods for coverage enhancements for sidelink (sl) synchronization signal block (ssb) (s-ssb) between a transmit (tx) user equipment (ue) and a receive (rx) ue are disclosed herein. s-ssb frequency domain enhancement may use frequency hopping for s-ssb and/or s-ssb that use an increased number of physical radio bearers (prbs). s-ssb time domain enhancements may modify an s-ssb periodicity, a number of s-ssb per period, use a clear channel assessment (cca) (or listen before talk (lbt)) procedure, and/or transmit only some of a configured set of s-ssbs for an s-ssb periodicity. multi-beam s-ssb enhancement may index s-ssbs of a configured set and send those s-ssbs using beams corresponding to the indexes. s-ssb enhancement using frequency domain masking and/or time domain masking may apply different masks to one or more s-ssbs.
