Classification: CPC H  G | IPC G  H

Claim 0:
1. A method comprising:
determining, by a wireless user device, a global navigation satellite system (GNSS) as a synchronization reference source associated with a sidelink synchronization;
determining a slot number for sidelink communication, based on:
the GNSS being the synchronization reference source associated with a sidelink synchronization;
a subcarrier spacing index for sidelink; and
one or more time parameters associated with the GNSS,
wherein the determining the slot number is based on Floor((Tcurrent−Tref−OffsetDFN)*2μ)mod(10*2μ), where Tcurrent is a current Coordinated Universal Time (UTC) time obtained from the GNSS, Tref is a reference UTC time, OffsetDFN is, if configured, a direct frame number (DFN) offset value associated with a sidelink DFN or, if not configured, zero, and, wherein μ is the subcarrier spacing index for sidelink; and transmitting, based on the slot number, a sidelink synchronization signal from the wireless user device to a second wireless user device.
