A method, a computer-readable medium, and an apparatus are provided. The apparatus
may be a user equipment (UE). The apparatus may transmit, to a base station, information
indicating a capability to communicate with one or more relay UEs. In addition, the
apparatus may receive, from the base station, configuration information associated with a
discovery procedure for identifying the one or more relay UEs. Further, the apparatus may
perform the discovery procedure based on the configuration information.

… the present disclosure relates generally to communication systems, and more particularly, to
configuration of a device-to device (D2D) UE by a base station for performing a network relay
search. D2D device-to device … For example, if the discovery procedure identifies relay UE
506 or relay UE 508 but the configuration information does not indicate a threshold backhaul
link quality between a relay UE and the eNB 502 and/or a threshold link quality between
a relay UE and the UE 504, the UE 504 may select either relay UE 506 or relay UE 508. …
