9. A first wireless transmit/receive unit (WTRU) comprising circuitry, including a transmitter, a receiver, a processor and memory, configured to:
receive one or more data transmissions from a second WTRU;
determine to use, for triggering relay reselection, one of (i) sidelink reference signal received power measurements associated with the one or more data transmissions or (ii) sidelink reference signal received power measurements associated with one or more discovery transmissions received from the second WTRU, wherein the determination is based on:
a precedence of at least one of (i) the sidelink reference signal received power measurements associated with the one or more data transmissions and (ii) the sidelink reference signal received power measurements associated with the one or more discovery transmissions; and
availability of the sidelink reference signal received power measurements associated with the one or more data transmissions; and
perform the relay reselection based on the determined one of (i) the sidelink reference signal received power measurements associated with the one or more data transmissions or (ii) the sidelink reference signal received power measurements associated with the one or more discovery transmissions failing to satisfy one or more thresholds.
