Abstract
In one embodiment, the present disclosure provides an evolved Node B (eNB) that includes a device-to-device (D2D) module configured to allocate at least one D2D discovery region including at least one periodic discovery zone, the at least one periodic discovery zone including a first plurality of resource blocks in frequency and a second plurality of subframes in time, the D2D module further configured to configure a User Equipment (UE) to utilize the at least one D2D discovery region for transmitting a discovery packet.
Claims24
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.
A method comprising:
- allocating, by an evolved Node B (eNB), a plurality of periodic discovery zones for device-to-device (D2D) discovery, wherein:
- each of the plurality of periodic discovery zones includes a first plurality of resource blocks and a second plurality of subframes;
- and
- 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;
- allocating, by D2D circuitry included in the eNB, a portion of each of the plurality of periodic discovery zones according to a cell reuse plan;
- signaling the partitioning of the plurality of periodic discovery zones;
- and
- configuring, by the eNB, a User Equipment (UE) to utilize at least one of the plurality of periodic discovery zones for transmission of a discovery message.
A User Equipment (UE) comprising:
- device-to-device (D2D) discovery circuitry configured to transmit a discovery message utilizing at least one of a plurality of periodic D2D discovery zones allocated according to a cell reuse plan;
- wherein:
- each of the plurality of periodic discovery zones includes a first plurality of resource blocks and a second plurality of subframes;
- and
- 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.
A non-transitory computer readable medium comprising instructions that when executed by a processor result in performance of the following operations comprising:
- allocating, by an evolved Node B (eNB), a plurality of periodic discovery zones for device-to-device (D2D) discovery, wherein:
- each of the plurality of periodic discovery zones includes a first plurality of resource blocks and a second plurality of subframes;
- and
- 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;
- allocating, by D2D circuitry included in the eNB, a portion of each of the plurality of periodic discovery zones according to a cell reuse plan;
- signaling the partitioning of the plurality of periodic discovery zones;
- and
- configuring, by the eNB, a User Equipment (UE) to utilize at least one of the plurality of periodic discovery zones for transmission of a discovery message.
