Wireless communication system, the integrated base station and terminal

A plurality of base stations cooperate, the base station cooperative communication method of simultaneously communicating to a plurality of terminals are likely to increase the communication capacity system can be provided. On the other hand, by the number of number and receiving antennas of a terminal system handled simultaneously increases, the number of information of the channel to be exchanged between the transmitter, substantial overhead to feed back channel information measured by the terminal is increased there is a case that does not lead to increased throughput. The terminal is not necessary to be always maximize communication capacity that can be provided as a system or communication speed to request, it may be performed between the base station cooperative communication when necessary, housed in cooperative communication between the base station it is necessary to select the should do terminal. Dividing a frame time of a certain period of time, the time zone in which one base station at the same time to avoid interference between base station performs time-division multiplex communication between the base station holds the transmission right (at the base station division multiplexing) When communicates by switching the time zone in which simultaneous communication between a plurality of base stations (base station simultaneous communication).
