Abstract

Systems and methods are described for configuring device to device communication. Communication information may be received at an access node identifying at least two wireless devices comprising a device to device communication group. NACK messages may be received from a plurality of wireless devices proximate to the communication group. Data may be retransmitted to the plurality of wireless devices proximate to the communication group based on the received NACK messages, wherein the at least two wireless device comprising the communication group perform device to device communication based on the resources used for retransmission.

Claims

1. A method for configuring device to device communication, the method comprising:

receiving, at an access node, device to device communication information identifying at least two wireless devices comprising a device to device communication group;

transmitting data to a plurality of wireless devices proximate to the communication group, wherein the plurality of wireless devices are not part of the communication group;

receiving NACK messages from the plurality of wireless devices proximate to the communication group corresponding to the transmitted data; and

retransmitting data to the plurality of wireless devices proximate to the communication group based on the received NACK messages, wherein the at least two wireless devices comprising the communication group perform device to device communication during a transmission time interval for the retransmission.

2. The method of claim 1, further comprising:

instructing the plurality of wireless devices proximate to the communication group to transmit a NACK message to the access node when the plurality of wireless devices successfully receive data.

3. The method of claim 2, further comprising:

determining a location for the communication group;

identifying a plurality of wireless devices within a threshold distance from the determined location for the communication group as proximate to the communication group;

instructing the plurality of wireless devices proximate to the communication group to transmit a NACK message to the access node when the plurality of wireless devices successfully receive a packet.

4. The method of claim 1, wherein the transmission time interval is reserved for downlink transmissions from the access node to wireless devices.

5. The method of claim 1, further comprising:

determining the transmission time interval for the retransmission; and

transmitting the determined transmission time interval to the communication group such that the determined transmission time interval is implicitly assigned for device to device communication for the communication group.

6. The method of claim 1, further comprising:

instructing the plurality of wireless devices proximate to the communication group to transmit an ACK message to the access node in association with the retransmission when the retransmitted data is unsuccessfully received.

7. A method for configuring device to device communication, the method comprising:

receiving, at an access node, device to device communication information identifying at least two wireless devices comprising a device to device communication group;

receiving data from a plurality of wireless devices proximate to the communication group, wherein the plurality of wireless devices are not part of the communication group;

transmitting NACK messages to the plurality of wireless devices proximate to the communication group corresponding to the received data; and

receiving retransmitted data from the plurality of wireless devices proximate to the communication group based on the transmitted NACK messages, wherein the at least two wireless devices comprising the communication group perform device to device communication during a transmission time interval for the retransmission.

8. The method of claim 7, further comprising:

transmitting the NACK messages to the plurality of wireless devices proximate to the communication group when data is successfully received from the wireless devices.

9. The method of claim 8, further comprising:

determining a location for the communication group;

identifying a plurality of wireless devices within a threshold distance from the determined location for the communication group as proximate to the communication group;

transmitting the NACK messages to the plurality of wireless devices proximate to the communication group when data is successfully received from the wireless devices.

10. The method of claim 7, wherein the transmission time interval is reserved for uplink transmissions from the plurality of wireless devices to the access node.

11. The method of claim 7, further comprising:

determining the transmission time interval for the retransmission; and

performing device to device communication by transmitting data, by at least one wireless device of the communication group, during the determined transmission time interval.

12. The method of claim 7, further comprising:

transmitting ACK messages in association with the retransmission to the plurality of wireless devices proximate to the communication group when the retransmitted data is unsuccessfully received.

13. A system for configuring device to device communication, the system comprising:

an access node with a processor configured to;

receive, at the access node, device to device communication information identifying at least two wireless devices comprising a device to device communication group;

transmitting data to a plurality of wireless devices proximate to the communication group, wherein the plurality of wireless devices are not part of the communication group;

receive NACK messages from the plurality of wireless devices proximate to the communication group corresponding to the transmitted data; and

retransmit data to the plurality of wireless devices proximate to the communication group based on the received NACK messages, wherein the at least two wireless devices comprising the communication group perform device to device communication during a transmission time interval for the retransmission.

14. The system of claim 13, where the access node is further configured to:

instruct the plurality of wireless devices proximate to the communication group to transmit a NACK message to the access node when the plurality of wireless devices successfully receive data.

15. The system of claim 14, where the access node is further configured to:

determine a location for the communication group;

identify a plurality of wireless devices within a threshold distance from the determined location for the communication group as proximate to the communication group;

instruct the plurality of wireless devices proximate to the communication group to transmit a NACK message to the access node when the plurality of wireless devices successfully receive a packet.

16. The system of claim 13, wherein the transmission time interval is reserved for downlink transmissions from the access node to wireless devices.

17. The system of claim 13, where the access node is further configured to:

determine the transmission time interval for the retransmission; and

transmit the determined transmission time interval to the communication group such that the determined transmission time interval is implicitly assigned for device to device communication for the communication group.
