Abstract

Interference potential may be determined between user equipment (UE) based on distance between the UEs and location information. Half duplex communication on orthogonal frequency division multiplexing (OFDM) resources may be scheduled based on the determined interference potential.

First claim

What is claimed is:

1. A method performed by a network device, the method comprising:
receiving, by the network device, satellite based location information from each user equipment (UE) of a plurality of UEs, wherein the received location information includes a geographical proximity between each UE of the plurality of UEs;
determining, by the network device, an interference potential for each UE of the plurality of UEs based on a determined distance between a first UE and a second UE of the plurality of UEs from the received location information; and
scheduling, by the network device, half duplex communication on a plurality of orthogonal frequency division multiplexing (OFDM) resources for the first UE and the second UE based on the determined interference potential, wherein the first UE is scheduled to receive information and the second UE is scheduled to transmit information on a substantially same time slot related to one of the plurality of OFDM resources when the determined distance is above a threshold value.

2. The method of claim 1 further comprising:
requesting, by network device, that each UE of the plurality of UEs perform a measurement associated with determining their respective location to send to the network device.

3. The method of claim 1 further comprising:
analyzing, by the network device, timing advance information of communications received from the plurality of UEs.

4. The method of claim 1 further comprising:
scheduling, by the network device, half duplex communication resources according to a transmit power level of one of the plurality of UEs.

5. The method of claim 1 further comprising:
determining, by the network device, another interference potential between the plurality of UEs on a condition that a UE of the plurality of UEs is communicating with the network device; and
updating the scheduled half duplex communication on the plurality of OFDM resources based on the determined another interference potential.

6. The method of claim 1 further comprising:
updating the scheduling of the half duplex communication on the plurality of OFDM resources on any one of a time slot-by-time slot basis, a frame-by-frame basis, or a multiframe-by-multiframe basis.

7. The method of claim 1 further comprising:
monitoring, by the network device, half duplex communication resource usage.

8. The method of claim 1 further comprising:
grouping, by the network device, the plurality of UEs as a single entity; and
scheduling, by the network device, uplink or downlink communication resources to the group.

9. The method of claim 1 further comprising:
determining, by the network device, path loss information of communications received from the plurality of UEs.

10. A non-transitory computer-readable program product with stored instructions executable by a computer, the instructions comprising:
instructions to receive satellite based location information from each user equipment (UE) of a plurality of UEs, wherein the received location information includes a geographical proximity between each UE of the plurality of UEs;
instructions to determine an interference potential for each UE of the plurality of UEs based on a determined distance between a first UE and a second UE of the plurality of UEs from the received location information; and
instructions to schedule half duplex communication on a plurality of orthogonal frequency division multiplexing (OFDM) resources for the first UE and the second UE based on the determined interference potential, wherein the first UE is scheduled to receive information and the second UE is scheduled to transmit information on a substantially same time slot related to one of the plurality of OFDM resources when the determined distance is above a threshold value.

11. A network device comprising:
a receiver configured to receive satellite based location information from each user equipment (UE) of a plurality of UEs, wherein the received location information includes a geographical proximity between each UE of the plurality of UEs;
a processor configured to determine an interference potential for each UE of the plurality of UEs based on a determined distance between a first UE and a second UE of the plurality of UEs from the received location information; and
the processor further configured to schedule half duplex communication on a plurality of orthogonal frequency division multiplexing (OFDM) resources for the first UE and the second UE based on the determined interference potential, wherein the first UE is scheduled to receive information and the second UE is scheduled to transmit information on a substantially same time slot related to one of the plurality of OFDM resources when the determined distance is above a threshold value.

12. The network device of claim 11 further comprising a transmitter configured to send scheduling information of the scheduled half duplex communication of the plurality of OFDM resources to the plurality of UEs.

13. The network device of claim 11 , wherein the network device is any one of a core network element, a radio resource manager (RRM), or a base station.

14. The network device of claim 11 further comprising:
the processor further configured to determine an interference potential between the plurality of UEs on a condition that a UE of the plurality of UEs is communicating with the network device; and
the processor configured to update the scheduled half duplex communication of the plurality of OFDM resources based on the determined interference potential.

15. The network device of claim 11 further comprising:
the processor further configured to group the plurality of UEs as a single entity; and
the processor further configured to schedule uplink or downlink communication resources to the group.
