Abstract  Abstract

The invention generally claims an apparatus used in LTE network discovery and proximity service to the device (D2D) for signalling method user equipment (UE) and an enhanced Node B (eNB) of the embodiment. In some embodiments the UE receives information about cell D2D the discovery resource cell configuration information. the configuration information comprises D2D resource cell has been logically divided into a plurality of discovery resource cell indication. UE within the discovery time period using the plurality of discovery D2D discovery resource in the resource pool of the first sub discovery resource pool to perform initial transmission of the discovery signal. UE within the discovery time period using the plurality of discovery in the resource pool except the first discovered outside the resource pool that additional D2D resource cell for performing a plurality of additional transmitting the discovery signal. Other apparatus and method are also described.

Embodiments of user equipment (UE) an enhanced node B (eNB) and methods of signaling for proximity services and device-to-device (D2D) discovery in an LTE network are generally described herein. In some embodiments the UE receives configuration information for a D2D discovery resource pool of a cell. The configuration information includes an indication that the D2D discovery resource pool has been logically divided into a plurality of sub-discovery resource pools. The UE performs an initial transmission of a discovery signal in a discovery period using a single D2D discovery resource from a first sub-discovery resource pool of the plurality of sub-discovery resource pools. The UE performs a number of additional transmissions of the discovery signal in the discovery period using additional D2D discovery resources from sub-discovery resource pools of the plurality of sub-discovery resource pools other than the first sub-discovery resource pool. Other apparatuses and methods are also described.
