Abstract:
A cellular wireless communication system having mobile stations, base stations and connection switching stations for controlling said base stations, and for communicating between said mobile stations and said base stations by time division multiplexing connections, said cellular wireless communication system comprising:a mobile station;a first base station configured to communicate with said mobile station over a communication channel;at least one other base station, wherein said mobile station, during communication with said first base station, is configured to receive a plurality of control channels from said first base station and said at least one other base station to measure a plurality of path losses therebetween, and is further configured to transmit a plurality of path loss information showing the measured plurality of path losses to said first base station; anda connection switching station, wherein said first base station is configured to transmit a first reception signal received from said mobile station to said connection switching station, to determine that said at least one other base station has a smaller path loss than said first base station based on said plurality of path loss information, and in accordance therewith to indicate said communication channel to said at least one other base station,wherein said at least one other base station is configured to receive the indicated communication channel and to measure a signal-to-interference wave power ratio thereof, and when the measured signal-to-interference wave power ratio is larger than a first threshold value, to transmit, to said connection switching station, a second reception signal received on said communication channel from said mobile station, andwherein said connection switching station is configured to combine said first reception signal and said second reception signal into a composite reception signal, to perform decoding processing to said composite reception signal, and to output the decoded composite reception signal.
