<p>For saving radio resources and reducing power consumption, a base station (101) performs the training of obtaining correlation information for correlating reception quality of a packet channel transmitted from a terminal (102) to corresponding transmission power of an accompanying channel, obtains the predicted value of the reception quality of the packet channel by using the transmission power of the accompanying channel based on the correlation information, and controls data transmission by the packet channel based on the predicted value. The base station (101) transmits transmission control information for controlling the transmission of the reception quality of the packet channel by the terminal (102) through the accompanying channel. The terminal (102) controls the transmission of the reception quality of the packet channel based on transmission control information contained in the data of the accompanying channel transmitted from the base station (101). This system is applicable, for example, to a W-CDMA type communication system.</p> |
