Abstract

A wireless access point controls wireless channels in a wireless repeater chain. The wireless access point exchanges wireless user data with User Equipment (UEs) over the wireless repeater chain. The wireless access point monitors average UE data throughput through the wireless repeater chain, variance in the average UE throughput, and an amount of Guaranteed Bit Rate (GBR) connections through the wireless repeater chain. The wireless access point disables wireless channels when the average UE data throughput falls below a data threshold and the amount of GBR connections exceeds a connection threshold. The wireless access point selects wireless channels to disable based on the variance in the average UE throughput. The wireless access point transfers instructions to selected wireless repeaters to disable the selected wireless channels.

Claims

1. A method of operating a wireless access point to control wireless channels in a wireless repeater chain, the method comprising:

exchanging wireless user data with multiple User Equipment (UEs) over the wireless repeater chain;

monitoring average UE data throughput through the wireless repeater chain and a variance in the average UE throughput;

monitoring an amount of Guaranteed Bit Rate (GBR) connections through the wireless repeater chain;

when the average UE data throughput falls below a data threshold and when the amount of GBR connections exceeds a connection threshold, then selecting one of the wireless channels to disable at a wireless repeater based on the variance in the average UE throughput; and

transferring an instruction to the wireless repeater to disable the one of the wireless channels.

2. The method of claim 1 wherein selecting the one of the wireless channels to disable comprises selecting one of the wireless channels having a highest variance in the average UE throughput.

3. The method of claim 1 wherein selecting the one of the wireless channels to disable comprises selecting one of the wireless channels having a highest number of GBR connections.

4. The method of claim 1 wherein selecting the one of the wireless channels to disable comprises selecting a number of the wireless channels to disable based on the variance in the average UE throughput.

5. The method of claim 1 wherein the wireless repeater comprises a far-edge wireless repeater in the wireless repeater chain.

6. The method of claim 1 comprising selecting a number of wireless repeaters based on the variance in the average UE throughput.

7. The method of claim 1 wherein selecting the one of the wireless channels to disable at the wireless repeater comprises selecting one of the wireless channels having a highest variance in the average UE throughput at a far-edge wireless repeater.

8. The method of claim 1 wherein the wireless access point comprises an eNodeB.

9. The method of claim 1 wherein the wireless channels comprise Long Term Evolution channels.

10. The method of claim 1 wherein a digital signal processor in the wireless repeater attenuates energy in the one of the wireless channels responsive to the instruction.

11. A wireless access point to control wireless channels in a wireless repeater chain, the wireless access point comprising:

a wireless transceiver system configured to exchange wireless user data with multiple User Equipment (UEs) over the wireless repeater chain;

a data processing system configured to monitor average UE data throughput through the wireless repeater chain, variance in the average UE throughput, and an amount of Guaranteed Bit Rate (GBR) connections through the wireless repeater chain; and

the data processing system configured, when the average UE data throughput falls below a data threshold and when the amount of GBR connections exceeds a connection threshold, to select one of the wireless channels to disable at a wireless repeater based on the variance in the average UE throughput and transfer an instruction to the wireless repeater to disable the one of the wireless channels.

12. The wireless access point of claim 11 wherein the data processing system is configured to select one of the wireless channels having a highest variance in the average UE throughput.

13. The wireless access point of claim 11 wherein the data processing system is configured to select one of the wireless channels having a highest number of GBR connections.

14. The wireless access point of claim 11 wherein the data processing system is configured to select a number of the wireless channels to disable based on the variance in the average UE throughput.

15. The wireless access point of claim 11 wherein the data processing system is configured to select a far-edge wireless repeater in the wireless repeater chain.

16. The wireless access point of claim 11 wherein the data processing system is configured to select a number of wireless repeaters based on the variance in the average UE throughput.

17. The wireless access point of claim 11 wherein the data processing system is configured to select one of the wireless channels having a highest variance in the average UE throughput at a far-edge wireless repeater.

18. The wireless access point of claim 11 wherein the wireless access point comprises an eNodeB.

19. The wireless access point of claim 11 wherein the wireless channels comprise Long Term Evolution channels.

20. The wireless access point of claim 11 wherein a digital signal processor in the wireless repeater attenuates energy in the one of the wireless channels responsive to the instruction.
