Abstract  Abstract

and device for resource distribution equipment (D2D) finds that the user equipment (UE) and the method of the embodiment is generally described herein. In some embodiments the UE can be evolved node B (eNB) receives the indication that resource signaling for transmitting a discovery signal in the LTE operating range. The discovery signal may include discovery range the discovery range may include a plurality of physical resource blocks (PRB) and a plurality of sub-frames. the UE may be sent for one or more other UE receiving a discovery signal for the discovery range of some D2D finds in the PRB. PRB for transmitting the discovery signal can be determined according to the multi-hop mode to provide frequency diversity of the increased bandwidth of the discovery range. hopping mode may comprise a sub-frame or combined subframe in/hopping between sub-frames.

Embodiments of a user equipment (UE) and method for resource allocation and device-to-device (D2D) discovery hopping are generally described herein. In some embodiments the UE may receive signaling from an enhanced node B (eNB) indicating discovery resources to transmit discovery signals on within an LTE operation zone. The discovery resources may include a discovery zone which may comprise a plurality of physical resource blocks (PRBs) and a plurality of subframes. The UE may transmit a discovery signal for receipt by one or more other UEs for D2D discovery within some of the PRBs of the discovery zone. The PRBs for the transmission of the discovery signal may be determined in accordance with a hopping mode to provide increased frequency diversity within a bandwidth of the discovery zone. The hopping mode may comprise intra-subframe hopping inter-subframe hopping or joint intra/inter-subframe hopping.
