Claim of US Patent No. 10,251,187

1. An apparatus of a user equipment (UE), the apparatus 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;
decode a transmission probability factor from an evolved Node-B (eNB) serving a cell associated with the UE, the transmission probability factor indicating a probability of transmission during a discovery period; and
encode a D2D discovery signal for an initial transmission during the 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 the transmission probability factor, and
wherein the discovery period is a Type 1 D2D discovery period for non-UE specific transmissions or a Type 2 D2D discovery period for UE-specific transmissions, and the initial transmission takes place during contiguous resource blocks of the subframe; and
memory, the memory coupled to the processing circuitry and configured to store the transmission probability factor.
