Interference mitigation
View Patent ↗Data is transmitted from a first base station using a first sub-channel at a first power level. An indication that a first wireless device is in a potential interference location is received. The first wireless device is receiving data from a second base station. Data is transmitted from the first base station using the first sub-channel at a second power level when a second wireless device receiving data from the first base station on the first sub-channel is associated with an indicator of lower priority. The second power level is lower than the first power level.
1. A method of operating a communication system, comprising:
transmitting data from a first base station using a first sub-channel at a first power level;
receiving an indication that a first wireless device is in a potential interference location, wherein the first wireless device is receiving data from a second base station; and,
transmitting data from the first base station using the first sub-channel at a second power level when a second wireless device receiving data from the first base station on the first sub-channel is associated with an indicator of lower priority, wherein the second power level is lower than the first power level.
2. The method of claim 1 , further comprising:
transmitting data from the first base station using the first sub-channel at the first power level when the indication that the first wireless device is in the potential interference location indicates that the first wireless device is not in the potential interference location.
3. The method of claim 1 , wherein the indicator of lower priority is based on an indicator of available resources associated with the first base station.
4. The method of claim 1 , wherein the indicator of lower priority is based on a service flow classification associated with the second wireless device.
5. The method of claim 1 , further comprising:
transmitting data from the first base station using the first sub-channel at the first power level after a pre-determined period of time has elapsed.
6. The method of claim 1 , wherein the indication that the first wireless device is in the potential interference location is based on RF signal conditions.
7. The method of claim 1 , wherein the indication that the first wireless device is in the potential interference location is based on a received signal strength indication (RSSI).
8. The method of claim 1 , wherein the indication that the first wireless device is in the potential interference location is based on a carrier to interference and noise ratio (CINR).
9. The method of claim 1 , wherein the indication that the first wireless device is in the potential interference location is based on a modulation and coding scheme associated with the first wireless device.
10. The method of claim 1 , wherein data is transmitted on the first sub-channel using a first sector of the first base station and the indication that the first wireless device is in the potential interference location is based on a signal strength indicator associated with the first wireless device that is measured by a second sector of the first base station.
11. A method of operating a communication system, comprising:
transmitting data from a first base station using a first sub-channel in each frame;
receiving an indication that a first wireless device is in a potential interference location, wherein the first wireless device is receiving data from a second base station; and,
transmitting data from the first base station using the first sub-channel in less than every frame when a second wireless device receiving data from the first base station on the first sub-channel is associated with an indicator of lower priority.
12. The method of claim 11 , further comprising:
transmitting data from the first base station using the first sub-channel in each frame after a pre-determined period of time has elapsed.
13. The method of claim 11 , wherein the indicator of lower priority is based on an indicator of available resources associated with the first base station.
14. The method of claim 11 , wherein the indication that the first wireless device is in the potential interference location is based on a received signal strength indication (RSSI).
15. The method of claim 11 , wherein the indication that the first wireless device is in the potential interference location is based on a carrier to interference and noise ratio (CINR).
16. The method of claim 11 , wherein data from the first base station using the first subchannel is transmitted using a first sector of the first base station and the indication that the first wireless device is in the potential interference location is based on a signal strength indicator associated with the first wireless device that is measured by a second sector of the first base station.
