Radio resources are saved, and power consumption is reduced. A base station 101 carries out training for obtaining correlation information that correlates the reception quality of a packet channel transmitted from a terminal 102 and the transmission power of an associated channel, and based on the correlation information, uses the transmission power of the associated channel to obtain a predicted value of the reception quality of the packet channel, and controls the transmission of data through the packet channel based on that predicted value. In addition, the base station 101 transmits through the associated channel transmission control information for controlling the transmission of the reception quality of the packet channel by the terminal 102. The terminal 102 controls the transmission of the reception quality of the packet channel based on the transmission control information included in the data of the associated channel transmitted from the base station 101. The present invention can be applied to, for example, a communications system of a W-CDMA system. |
