1. A wireless transmit/receive unit (WTRU) comprising:
a processor; and
a transceiver operatively coupled to the processor;
the processor and the transceiver configured to send, to a network, a registration message indicating the WTRU is capable of device-to-device (D2D) communication;
the processor and the transceiver configured to send, to the network, a request for assistance in discovering at least one other WTRU in proximity to the WTRU;
the processor and the transceiver configured to receive, from the network, in response to the request for assistance in discovering at least one other WTRU in proximity to the WTRU, assistance information including filtering information;
the processor and the transceiver configured to, using the assistance information, perform a device discovery procedure that comprises monitoring for signals from at least one other WTRU in proximity to the WTRU using the filtering information;
the processor and the transceiver configured to send, to the network, an indication of a result of the device discovery procedure;
the processor and the transceiver configured to receive, from the network, after sending the indication, information indicating one or more service identifiers;
the processor and the transceiver configured to transmit a message to the at least one other WTRU, wherein the message is associated with a service that corresponds to at least one of the one or more service identifiers; and
the processor and the transceiver configured to transmit application data directly to the at least one other WTRU.
