Abstract
A HSDPA type mobile communication system includes a base station and a mobile station. The base station sets the uplink control channel with the mobile station to transmit a pilot signal. The mobile station measures a reception quality of the pilot signal to transmit the quality information to the base station using the uplink quality control channel. The base station performs transmission control of data for the mobile station using the quality information. The mobile station is set to perform control of starting and stopping transmission of the quality information so that the quality information is transmitted only as required. Therefore, power consumption in the mobile station can be reduced, interference wave power in the uplink can be reduced, and capacity of the uplink can be increased.
