USER EQUIPMENT AND METHOD FOR RESOURCE ALLOCATION AND DEVICE-TO-DEVICE DISCOVERY HOPPING

摘要

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-sub frame hopping, inter-subframe hopping or joint intra/inter-subframe hopping.

1. User Equipment (UE) arranged for device-to-device (D2D) discovery operations in an LTE network, the UE configured to:
receive signaling from an enhanced node B (eNB) indicating discovery resources within an LTE operation zone, the discovery resources comprising a plurality of physical resource blocks (PRBs); and transmit a discovery signal for receipt by one or more other UEs for D2D discovery within at least some PRBs of the discovery resources, wherein the PRBs for transmission of the discovery signal are in accordance with a hopping mode.
