Wireless communications systems and methods related to multiple starting points for new radio sidelink transmission over unlicensed band are provided. In some aspects, a UE may perform a channel access procedure to access a first physical sidelink shared channel (PSSCH) transmission resource of an unlicensed new radio spectrum. In some aspects, the first PSSCH transmission resource may be reserved by a control message and may include a plurality of transmission starting points. Further, the first UE may transmit first data to a second UE via the first PSSCH transmission resource starting at a later transmission starting point than one or more prior transmission starting points of the plurality of transmission starting points when the performing the channel access procedure fails at each of the one or more prior transmission starting points.
