Abstract
A system and method for device to device (D2D) network-assisted device discovery are provided. The method includes initiating the D2D network-assisted device discovery of a receiving UE to enable a target UE and the receiving UE to establish a D2D communication. The method also includes performing a discovery feasibility measurement to determine whether a D2D communication between the target UE and the receiving UE is feasible. The method further includes transmitting a discovery setup message and receiving a discovery report from the target UE.
Claims36
For use in a wireless communication network, a user equipment (UE) comprising:
- a plurality of antennas configured to communicate with at least one of an enhanced NodeB (eNB) via a cellular communication link and second user equipment via a device to device (D2D) communication, the D2D wireless communication comprising a direct wireless communication;
- and
- processing circuitry coupled to the plurality of antennas, the processing circuitry configured to perform a network-assisted device discovery of the second UE, wherein the eNB assists in the UE in the network-assisted device discovery.
For use in a wireless communication network, an enhanced NodeB (eNB) configured to communicate with a plurality of user equipments (UEs), the eNB comprising:
- a plurality of antennas configured to communicate with at least one UE;
- and
- processing circuitry coupled to the plurality of antennas, the processing circuitry configured to cause a first UE to perform a device-to-device (D2D) network-assisted device discovery of a second UE to enable the first UE and the second UE to establish a D2D communication.
