1. An apparatus, comprising:
a memory; and
a processor in communication with the memory and configured to cause a user equipment device (UE) to:
detect one or more synchronization signals from a base station operating according to a first radio access technology (RAT) over a Uu interface between the UE and the base station, wherein the synchronization signals are detected in resources allocated for communication according to the first RAT;
determine, based on the synchronization signals, a reference timing or a reference frequency for sidelink communication over a PC5 interface with another UE according to a second RAT; and
encode physical channels for transmission to the other UE over the PC5 interface in accordance with the second RAT.
