Abstract: Embodiments of the present invention generally relate to enhanced physical downlink control channel (EPDCCH) search space determination. In one embodiment, a base station may identify an index of the current EPDCCH occasion period, each EPDCCH occasion period including a number of subframes, and the subframes being divided to a number of search units. A distribution of EPDCCH candidates corresponding to at least one EPDCCH aggregation level in the EPDCCH occasion period may be determined based on the index of the EPDCCH occasion period and the number of search units in the EPDCCH occasion period. The base station may then select, from the distribution of the EPDCCH candidates, an EPDCCH candidate for transmitting downlink control information (DCI) to a UE.

Abstract: Systems and techniques for managing the use of discovery resources in device to device communication-capable devices. A message is configured for transmission to one or more user devices by a base station to indicate permission or denial of discovery resources, and based on the message, one or more of the user devices receiving the message uses, or is inhibited from using, the resource. Indication of permission or denial may, in various embodiments designate all discovery resources in general, specific resources assigned to groups and allocated to a specific user device, or groups of resources, with permission or denial relating to all members of a group.
