摘要： When a subscriber station (SS) encounters interference caused an interfering base station (BS), the interference can be mitigated regardless of whether the interfering base station is a CSG-Closed BS or whether the SS is connected to a serving BS. If the SS is not connected to a serving BS and cannot access the interfering BS, the SS will signal the interfering BS directly to request the interfering BS to perform IM. If the SS is a legal user, and conditions to initiate IM are met, the interfering BS will perform IM until conditions to terminate IM are met. If the SS is connected to a serving BS, the serving BS will request the interfering BS to perform or terminate interference mitigation (IM) on behalf of the SS if certain conditions are satisfied.

摘要： A transmitter or receiver may use beamforming methods for transmitting or receiving a signal in a communication system. The method for transmitting includes determining a first beamforming weight associated with a total number of antennas in an antenna array. The method also includes transmitting a first signal in a first beam having a first beam width using the total number of antennas by applying the first predetermined beamforming weight. The method further includes determining a second beamforming weight associated with a first sub-array of antennas in the antenna array and determining a third beamforming weight associated with a second sub-array of antennas in the antenna array. The method still further includes transmitting a second signal in a second beam having a second beam width using the first sub-array of antennas by applying the second beamforming weight and the second sub-array of antennas by applying the third beamforming weight.
