Claim:
1. A communication processing method used in a base station having a plurality of sectors, the communication processing method comprising: the base station receiving channel state information corresponding to all or some of spare coordinated groups from each of user devices, a first group including a plurality of coordinated groups arranged in advance, each of the coordinated groups being formed of two or more sectors, and the spare coordinated groups corresponding to each of the user devices being selected from the first group and including at least a service sector of best channel quality obtained by measurement of the user device, wherein the spare coordinated group for each user device includes all of the coordinated groups that contain the service sector of best channel quality; the base station specifying a user device group corresponding to each of coordinated groups included in each of coordinated group patterns, the user device group corresponding to the coordinated group including user devices of which the corresponding spare coordinated groups include the coordinated group; the base station performing user scheduling on each of the coordinated groups based on channel state information reported by the user devices of the user device group corresponding to the coordinated group; and the base station specifying a user device and a coordinated group pattern to use in transmission based on scheduling results of the coordinated groups, and then performing data transmission based on the specified user device and the specified coordinated group pattern; the base station obtaining an index of the service sector reported from each of the user devices; and the base station selectin for the user device, the spare coordinated groups including the service sector from the coordinated groups arranged in advance and reporting the spare coordinated groups to the user device, wherein when physical sector indexes of the sectors are different from each other, the index of the service sector is indicated by a physical sector index and when the physical sector indexes of the sectors are same as each other, the index of the service sector is indicated by an antenna index.
