Resource allocation for D2D discovery in an LTE network
First Claim
1. An apparatus of a user equipment (UE), comprising:
- processing circuitry, the processing circuitry configured to;
decode signaling with device-to-device (D2D) discovery configuration information, the discovery configuration information including a discovery resource pool with a set of subframes;
encode a D2D discovery signal for an initial transmission during a discovery period and using a subframe from the set of subframes in the discovery resource pool, wherein a probability that the UE is configured to transmit the discovery signal is based on a transmission probability factor from an evolved Node-B (eNB) serving a cell associated with the UE; and
cause additional transmissions of the discovery signal using at least another subframe of the set of subframes in the discovery resource pool, wherein each transmission of the additional transmissions is performed using at least two physical resource blocks per slot associated with the at least another subframe; and
memory, the memory coupled to the processing circuitry and configured to store the transmission probability factor.

Abstract
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.
