Abstract

Techniques described herein may provide for device discovery of direct communication paths, to enable direct mode communication, between communication devices. The discovery of the communication paths may be based on identifiers that may be defined at the application level and included in device discovery requests. In one implementation, the identifiers may be SIP-URIs (session initiation protocol (SIP)-uniform resource identifiers (URIs)).

receive a first application layer identifier that identifies a user of the UE;

form a layer-2 frame, the layer-2 frame including

a field designating the layer-2 frame as a device discovery frame for discovery using direct mode signaling between the UE and one or more other UEs,

the first application layer identifier, and

a second application layer identifier corresponding to one or more other users, associated with the one or more other UEs, with which discovery using direct mode signaling is to be performed; and

wirelessly broadcast the layer-2 frame.

2. The UE of claim 1, wherein the first and second application layer identifiers include session initiation protocol (SIP)-uniform resource identifiers (URIs).

3. The UE of claim 1, wherein the processing circuitry is further to:

form the layer-2 frame to additionally include a layer-2 address of the UE.
