Claim 18:
19. A non-transitory computer-readable medium containing instructions stored thereon, which, when executed by a user equipment (UE), cause the UE to perform actions, the instructions comprising:
at least one instruction configured to cause the UE to establish, with a peer sidelink UE, at least one sidelink communications link that each comprises one or more hops;
at least one instruction configured to cause the UE to estimate, while the UE is unsynchronized with respect to a network clock, a propagation delay between the UE and the peer sidelink UE based in part upon a relationship between a propagation time, between the UE and the peer sidelink UE, and Reference Signal Received Power (RSRP); and
at least one instruction configured to cause the UE to determine, while the UE is unsynchronized with respect to the network clock, a reference timing based on the estimated propagation delay.
