CONFIGURATION OF LAYER-1 DESTINATION ADDRESS FOR DEVICE-TO-DEVICE COMMUNICATIONS
First Claim
1. An apparatus comprising:
- a controller configured to receive a discovery request from first User Equipment (UE), to identify an application code to announce the first UE during a discovery procedure, and to provide the application code to the first UE;
the controller configured to receive an address request from the first UE for a device-to-device (D2D) communication with at least one second UE identified during the discovery procedure, to derive a Layer-1 destination address for the D2D communication, and to provide the Layer-1 destination address to the first UE and to the at least one second UE for pre-configuration of the Layer-1 destination address at the first UE and the at least one second UE before the D2D communication.

Abstract
Systems and methods that configured a Layer-1 destination address for D2D communications. One embodiment is a controller in a network that receives a discovery request from first User Equipment (UE), identifies an application code to announce the first UE during a discovery procedure, and provides the application code to the first UE. The controller receives an address request from the first UE for a D2D communication with one or more second UEs identified during the discovery procedure. The controller derives a Layer-1 destination address for the D2D communication, and provides the Layer-1 destination address to the first UE and to the at least one second UE for pre-configuration of the Layer-1 destination address at the first UE and the at least one second UE before the D2D communication.

9. A method comprising:
-
receiving a discovery request in a controller in a network from first User Equipment (UE); identifying an application code to announce the first UE during a discovery procedure; providing the application code from the controller to the first UE; receiving an address request from the first UE for a device-to-device (D2D) communication with at least one second UE identified during the discovery procedure; deriving a Layer-1 destination address for the D2D communication; and providing the Layer-1 destination address to the first UE and to the at least one second UE for pre-configuration of the Layer-1 destination address at the first UE and the at least one second UE before the D2D communication. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. An apparatus comprising:
-
first User Equipment (UE) configured to transmit a discovery request to a controller in a mobile network, to receive a discovery response from the controller indicating an application code to use to announce the first UE for a proximity service, and to discover at least one second UE for device-to-device (D2D) communication; the first UE configured to transmit an address request to the controller for the D2D communication with the at least one second UE, to receive an address response from the controller indicating a Layer-1 destination address for the D2D communication derived by the controller, and to initiate the D2D communication using radio resources based on the Layer-1 destination address. - View Dependent Claims (18, 19, 20)
