The method may include receiving, from the network, in response to the request for assistance in discovering the at least one other WTRU, assistance information including one or more of a unique identifier or filtering information. The method may include performing, using the assistance information, a device discovery procedure to discover the at least one other WTRU, wherein the device discovery procedure comprises at least one of: monitoring for signals from the at least one other WTRU using the assistance information, or sending a discovery announcement based on the assistance information and transmitting application data directly to the at least one other WTRU.
