Power efficient relay discovery protocol

A method of wireless communication, comprising:

• receiving at a user equipment (UE) a discovery signal from each of a plurality of relays;
• determining to select one of the plurality of relays based on the discovery signal from each relay;
• and
• sending to a selected relay a request for relaying with a base station based on the discovery signal when one of the plurality of relays is determined to be selected.

An apparatus for wireless communication, comprising:

• means for receiving discovery resource information from a base station;
• means for sending a discovery signal based on the discovery resource information;
• and
• means for receiving from at least one user equipment (UE) a request for relaying with the base station based on the discovery signal.
