<P>PROBLEM TO BE SOLVED: To make both scheduling of superior transmission efficiency and efficient notification of reception state information compatible. <P>SOLUTION: In a base station apparatus, a channel for transmitting transmission data to a terminal device is allocated, based on reception state information received from the terminal device. One grouping method is selected for each terminal device from among a plurality of grouping methods in which at least one channel is grouped, based on a data quantity index which is a value indicating the data quantity transmitted to each of the terminal devices. The base station apparatus comprises a request determining part which determines a request regarding reception state information which represents reception state for each group by the grouping method selected for each terminal device, and a request transmission part for transmitting a notification request information representing the determined request. <P>COPYRIGHT: (C)2009,JPO&INPIT |
