<P>PROBLEM TO BE SOLVED: To reduce control information for specifying a transmission method when transmitting both uplink data together with reception quality information and uplink data together with ACK/NACK, to reduce a delay generated when modifying the transmission method, and also to provide followability with respect to a modulation method and a coding rate of the uplink data specified from a base station device. <P>SOLUTION: A base station device transmits a signal permitting data transmission to the uplink, including resource allocation information specifying the time or frequency component with respect to an uplink data channel, to a mobile station device. The mobile station device calculates, on the basis of the resource allocation information, the resource amount of reception quality information disposed on the uplink data channel together with uplink data so as not to exceed a predetermined value and transmits, to the base station devices, the reception quality information together with the uplink data, according to the calculated resource quantity, by using the uplink data channel. <P>COPYRIGHT: (C)2010,JPO&INPIT |
