Priority-dependent transmission of sidelink synchronization signals

A method of operating a first user equipment (UE) of a wireless communications system, the method comprising:

• receiving, at the first UE, first sidelink (SL) synchronization signaling from each of one or more neighboring UEs from among a plurality of neighboring UEs;
• and
• determining, by the first UE, whether to transmit a second SL synchronization signaling, based on the received first SL synchronization signaling,
• wherein the determining includes,
• generating at least one adjusted transmission determination value by adjusting at least one of,
• a synchronization transmission threshold, or
• signal powers of the one or more neighboring UEs, and
• determining whether to transmit the second SL synchronization signaling based on the adjusted transmission determination value.

A first user equipment (UE), of a wireless communications system, the UE comprising:

• receiving means for receiving, at the first UE, first sidelink (SL) synchronization signaling from each of one or more neighboring UEs from among a plurality of neighboring UEs;
• and
• first determining means for determining, by the first UE, whether to transmit a second SL synchronization signaling, based on the received first SL synchronization signaling, wherein the first determining includes,
• generating means for generating at least one adjusted transmission determination value by adjusting at least one of,
• a synchronization transmission threshold, or
• signal powers of the one or more neighboring UEs, and
• second determining means for determining whether to transmit the second SL synchronization signaling based on the adjusted transmission determination value.
