Interference mitigation for control channels in a wireless communication network
First Claim
1. A method for wireless communication, comprising:
- generating a request by a user equipment (UE) to reduce interference on radio resources used for a control channel by a serving base station serving the UE;
sending the request to an interfering base station;
receiving, at the UE, the control channel on the radio resources from the serving base station; and
communicating with the serving base station via the control channel for interference mitigation for data transmission,wherein the generating the request comprises generating the request to include one or more of a transmit power level of the request, an identity of the serving base station, a duration over which the request is valid, priority of the request, or a combination thereof.

Abstract
Techniques for mitigating interference on control channels in a wireless communication network are described. In an aspect, high interference on radio resources used for a control channel may be mitigated by sending a request to reduce interference to one or more interfering stations. Each interfering station may reduce its transmit power on the radio resources, which may then allow the control channel to observe less interference. In one design, a user equipment (UE) may detect high interference on radio resources used for a control channel by a desired base station. The UE may send a request to reduce interference on the radio resources to an interfering base station, which may reduce its transmit power on the radio resources. The UE may receive the control channel on the radio resources from the desired base station and may observe less interference from the interfering base station.
