1. A method of wireless communication at a user equipment (UE), comprising:

  • receiving discovery resource information from a base station;

    determining at least one of a downlink signal-to-interference-plus-noise ratio (SINR), an uplink interference, or an uplink pathloss;

    deriving synchronization information from a macro network;

    refraining from sending a synchronization signal;

    sending a discovery signal based on the discovery resource information, wherein the discovery signal comprises the determined at least one of the downlink SINR, the uplink interference, or the uplink pathloss, and wherein the discovery signal does not include synchronization information; and

    receiving from at least one user equipment (UE) a request for relaying with the base station based on the discovery signal.
