1. An apparatus comprising:
a memory; and
at least one processor in communication with the memory and configured to cause a user equipment (UE) to:
detect one or more synchronization signals for sidelink synchronization;
based on the one or more synchronization signals, determine a reference timing to be used for a common synchronization of Long Term Evolution (LTE) sidelink communication on an LTE PC5 interface and New Radio (NR) sidelink communication on an NR PC5 interface in accordance with time division multiplexing (TDM) operation, wherein subframe boundaries of the LTE PC5 interface and the NR PC5 interface are aligned in time;
decode, from an Evolved Node-B (eNB) of an LTE network or a Next Generation Node-B (gNB) of an NR network, information related to priorities of:
one or more services configured for the LTE PC5 interface, and
one or more services configured for the NR PC5 interface; and
if the UE detects, during a time period, an in-device conflict between a service configured for the LTE PC5 interface and a service configured for the NR PC5 interface, determine which of the services to support during the time period based on the corresponding priorities.
