1. An evolved Node B (eNB) comprising:
- device-to-device (D2D) circuitry configured to allocate a plurality of periodic discovery zones for D2D discovery, wherein;
the D2D circuitry allocates a portion of each of the plurality of periodic discovery zones according to a cell reuse plan;
each of the plurality of periodic discovery zones includes a first plurality of resource blocks and a second plurality of subframes;
the D2D circuitry is further configured to configure a User Equipment (UE) to utilize at least one of the plurality of periodic discovery zones for transmitting a discovery message;
the plurality of periodic discovery zones are partitioned such that the plurality of periodic discovery zones comprise at least one contention based discovery zone that is available to all D2D UE'"'"'s irrespective of their Radio Resource Control (RRC) connection status; and
transmitter circuitry to signal the partitioning of the plurality of periodic discovery zones.
