Abstract
A cluster-based cooperative communication system and method is provided for mitigating inter-cell interference effectively. A cluster-based cooperative communication method of a mobile station includes receiving allocation of a resource of a weighted subband mapped to one of preset cooperative base station clusters, the selected cooperative base station cluster having a group including a serving base station of the mobile station and dominant interfering base stations found by channel estimation, and communicating with the serving base station in cooperation with the dominant interfering base stations.
Claims8
A cluster-based cooperative communication method of a mobile station, the method comprising:
- receiving a cooperative base station cluster list;
- receiving allocation of a resource of a weighted subband mapped to a selected one of cooperative base station clusters within the received base station cluster list, the selected cooperative base station cluster having a group including a serving base station of the mobile station and dominant interfering base stations found by channel estimation;
- and
- communicating with the serving base station in cooperation with the dominant interfering base stations,
- wherein the receiving of the allocation of the resource comprises:
- reporting the selected cooperative base station cluster having the group including the serving base station and the dominant interfering base stations to the serving base station;
- and
- allocating, at the serving base station, the resource by weighting the subband mapped to the selected cooperative base station cluster to the mobile station.
A cluster-based cooperative communication method of a base station, the method comprising:
- transmitting a preset cooperative base station cluster list;
- allocating a resource of a weighted subband mapped to a selected one of the preset cooperative base station clusters to a mobile station, the selected cooperative base station cluster having a group including a serving base station of the mobile station and dominant interfering base stations found by channel estimation;
- and
- communicating with the mobile station in cooperation with the dominant interfering base stations,
- wherein the allocating of the resource to the weighted subband comprises:
- receiving the selected cooperative base station cluster having the group including the serving base station and the dominant interfering base stations from the mobile station;
- and
- allocating the resource by weighting the subband mapped to the selected cooperative base station cluster to the mobile station.
A cluster-based cooperative communication system, the system comprising:
- a mobile station for receiving a cooperative base station cluster list, for receiving allocation of a resource of a weighted subband mapped to a selected one of cooperative base station clusters within the received base station cluster list, the selected cooperative base station cluster having a group including a serving base station of the mobile station, and dominant interfering base stations found by channel estimation, and for communicating with the serving base station in cooperation with the dominant interfering base stations,
- wherein the mobile station reports the selected cooperative base station cluster having the group including the serving base station and the dominant interfering base stations to the serving base station, and the base station allocates the resource by weighting the subband mapped to the selected cooperative base station cluster to the mobile station.
A cluster-based cooperative communication system, the system comprising:
- a serving base station for transmitting a preset cooperative base station cluster list, for allocating a resource of a weighted subband mapped to a selected one of the preset cooperative base station clusters to a mobile station, the selected cooperative base station cluster having a group including a serving base station of the mobile station, and dominant interfering base stations found by channel estimation, and for communicating with the mobile station in cooperation with the dominant interfering base stations,
- wherein the serving base station receives the selected cooperative base station cluster having the group including the serving base station and the dominant interfering base stations from the mobile station, and the serving base station allocates the resource by weighting the subband mapped to the selected cooperative base station cluster to the mobile station.
