Claim:
1. User equipment (UE) enabled for proximity services (ProSe), the ProSe-enabled UE comprising hardware circuitry configured to: receive device-to-device (D2D) discovery-zone-configuration information from an enhanced node B (eNB) to indicate time and frequency resources and a periodicity of a discovery zone and to indicate one or more discovery zone operational parameters; monitor a first discovery period of a D2D discovery zone for D2D discovery signals transmitted by other UEs; receive discovery packets in the first discovery period from the other UEs; estimate a loading condition within the first discovery period; adapt a silencing factor based on the estimated loading condition within the first discovery period, where the silencing factor comprises a probability that the UE will not transmit a D2D discovery signal in a second discovery period that follows the first discovery period.
