Quality of service based downlink power allocation
View Patent ↗A first wireless device associated with a first profile is communicated with using a first transmitted power. A second wireless device associated with a second profile is communicated with using a second transmitted power. A third transmitted power is determined. The third transmitted power is associated with the first wireless device receiving data using a target modulation and coding scheme. A maximum transmitted power is determined to be exceeded if the third transmitted power is used to communicate with the first wireless device. The second wireless device is communicated with using a fourth transmitted power. The fourth transmitted power allows the third transmitted power to be used to communicate with the first wireless device without exceeding the maximum transmitted power.
1. A communication system, comprising:
a wireless station that communicates 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,
a control system instructing the wireless station to increase a first transmit power level for at least one of the first plurality of wireless devices and decrease a second transmit power level for at least one of the second plurality of wireless devices in response to determining the at least one of the first plurality of wireless devices is not receiving communication using at least a minimum target modulation and coding scheme.
2. The communication system of claim 1 , wherein the first quality of service is associated with a first service flow classification.
3. The communication system of claim 1 , wherein the second transmit power level is decreased based on the increased the first transmit power level.
4. The communication system of claim 1 , wherein the second transmit power level is decreased based on whether the increased the first transmit power level will cause the wireless station to exceed a maximum transmit power.
5. The communication system of claim 1 , wherein the communication system increases the first transmit power level for the at least one of the first plurality of wireless devices based on a target multi-antenna mode associated with the first plurality of wireless devices.
6. A method of operating a communication system, the method comprising:
sending wireless communication to a first plurality of wireless devices associated with a first quality of service;
sending wireless communication to a second plurality of wireless devices associated with a second plurality of wireless devices associated with a second quality of service;
increasing a first transmit power level for at least one of the first plurality of wireless devices in response to a determination that the at least one of the first plurality of wireless devices is not receiving communication using at least a minimum target modulation and coding scheme; and
decreasing a second transmit power level for at least one of the second plurality of wireless devices in response to the determination that the at least one of the first plurality of wireless devices is not receiving communication using at least the minimum target modulation and coding scheme.
7. The method of claim 6 , wherein the first quality of service is associated with a first service flow classification.
8. The method of claim 6 , wherein the decreasing the second transmit power level is based on the increasing the first transmit power level.
9. The method of claim 6 , wherein the decreasing the second transmit power level is based on whether the increased first transmit power level will cause the wireless station to exceed a maximum transmit power.
10. The method of claim 6 , wherein the increasing the first transmit power level is based on a target multi-antenna mode associated with the first plurality of wireless devices.
11. A method of operating a communication system, the method comprising:
determining that at least one of a first plurality of wireless devices associated with a first quality of service is not receiving communication using at least a minimum target modulation and coding scheme;
instructing a wireless station to increase a first transmit power level for at least one of the first plurality of wireless devices in response to the determination that at least one of the first plurality of wireless devices associated with the first quality of service is not receiving communication using at least the minimum target modulation and coding scheme; and
instructing the wireless station to decrease a second transmit power level for at least one of a second plurality of wireless devices associated with a second quality of service in response to the determination that at least one of the first plurality of wireless devices associated with the first quality of service is not receiving communication using at least the minimum target modulation and coding scheme.
12. The method of claim 11 , wherein the first quality of service is associated with a first service flow classification.
13. The method of claim 11 , wherein the instructing the wireless device to decrease the second transmit power level is based on the increased first transmit power level.
14. The method of claim 11 , wherein the instructing the wireless device to decrease the second transmit power level is based on whether the increased first transmit power level will cause the wireless station to exceed a maximum transmit power.
15. The method of claim 11 , wherein the instructing the wireless device to increase the first transmit power level is based on a target multi-antenna mode associated with the first plurality of wireless devices.
