Quality of service based multi-antenna mode switching
View Patent ↗A method of operating a communication system is disclosed. A first wireless device associated with a first profile is communicated with using a first multi-antenna mode. A second wireless device associated with a second profile is communicated with using the first multi-antenna mode. A network resource utilization is determined. It is determined that the network resource utilization satisfies a criteria. Based on the network resource utilization satisfying the criteria, at least one control message is sent that instructs the second wireless device to use a second multi-antenna mode.
1. A method of operating a communication system, comprising:
communicating by an access node with a first wireless device associated with a first profile using a first lower bandwidth multi-antenna mode;
communicating by the access node with a second wireless device associated with a second profile using the first lower bandwidth multi-antenna mode;
determining a network resource utilization;
determining a second network resource utilization associated with a plurality of wireless devices;
determining that the network resource utilization satisfies a criteria based on a relationship between the network resource utilization and the second network resource utilization; and,
based on the network resource utilization satisfying the criteria, sending at least one control message that instructs the second wireless device to use a second higher bandwidth multi-antenna mode.
2. The method of claim 1 , further comprising:
after sending the at least one control message, communicating with the second wireless device by the access node using the second multi-antenna mode.
3. The method of claim 1 , wherein the first profile is associated with a first quality of service to be provided to the first wireless device.
4. The method of claim 1 , wherein the first profile is associated with a first quality of service to be provided to a first service flow being communicated with said first wireless device.
5. The method of claim 1 , wherein the sending the at least one control message is further based on a signal quality indicator associated with the second wireless device satisfying a signal quality criteria.
6. The method of claim 5 , wherein the signal quality indicator is based on a signal to noise ratio.
7. The method of claim 5 , wherein the signal quality criteria is based on the network resource utilization.
8. A method of operating a communication system, comprising:
receiving wireless communication at an access node from a first plurality of wireless devices that are operating using a first lower bandwidth multi-antenna mode, the first plurality of devices being associated with a first quality of service;
receiving wireless communication at the access node from a second plurality of wireless devices that are operating using the first lower bandwidth multi-antenna mode, the second plurality of wireless devices being associated with a second quality of service;
determining a network resource utilization associated with the first plurality of wireless devices; and,
based on the network resource utilization satisfying a criteria, sending at least one message to at least one of the second plurality of wireless devices that the at least one of the second plurality of wireless devices is to switch to a second higher bandwidth multi-antenna mode.
9. The method of claim 8 , further comprising:
receiving wireless communication at the access node from the at least one of the second plurality of wireless devices using the second higher bandwidth multi-antenna mode.
10. The method of claim 8 , wherein the first quality of service is associated with a first service flow classification.
11. The method of claim 8 , wherein the sending at least one message to at least one of the second plurality of wireless devices is further based on signal quality indicators associated with the at least one of the second plurality of wireless devices.
12. The method of claim 11 , wherein the sending at least one message to at least one of the second plurality of wireless devices is further based on signal quality indicators associated with the at least one of the second plurality of wireless devices satisfying a signal quality criteria.
13. The method of claim 12 , wherein the signal quality criteria is based on an indicator of a signal to noise ratio associated with the at least one of the second plurality of wireless devices.
14. The method of claim 13 , wherein the signal quality criteria is further based on the network resource utilization.
15. A communication system, comprising:
a wireless station that communicates, using a first lower bandwidth multi-antenna mode, with a first plurality of wireless devices associated with a first quality of service, and with a second plurality of wireless devices associated with a second quality of service; and,
the communication system determining that a network resource utilization associated with the first plurality of wireless devices satisfies a criteria, and based on the determination the wireless station sends at least one message to at least one of the second plurality of wireless devices that the at least one of the second plurality of wireless devices is to switch to a second higher bandwidth multi-antenna mode to communicate with the wireless station.
16. The system of claim 15 , wherein the first quality of service is associated with a first service flow classification.
17. The system of claim 15 , wherein the sending at least one message to at least one of the second plurality of wireless devices is further based on signal quality indicators associated with the at least one of the second plurality of wireless devices.
18. The system of claim 17 , wherein the signal quality criteria is based on an indicator of a signal to noise ratio associated with the at least one of the second plurality of wireless devices.
19. The system of claim 18 , wherein the signal quality criteria is further based on the network resource utilization.
