Radio communication system
First Claim
1. A wireless communication system in site selection diversity transmit power control, wherein each base station determines whether the base station is a base station with a high possibility of being requested from a communication terminal to transmit data, based on a downlink state, in the communication terminal, of a downlink signal from the base station to the communication terminal, and transmits the determination result to a control station, and the control station transmits data for a downlink signal to the determined base station.

Abstract
In order to select a base station with the high possibility of being requested from a communication terminal to transmit data, using a downlink state report transmitted from the communication terminal to a base station, each base station determines whether the base station is a base station with the high possibility of being requested from the communication terminal to transmit data, and transmits the determination result to a control station as control information of flow between the control station and base station, and the control station transmits data to the base station.
