<P>PROBLEM TO BE SOLVED: To provide an apparatus and a method with which a plurality of slots to be two-dimensionally arranged in a frequency direction and a time direction are grouped into at least one of the frequency direction and the time direction depending on a state of a propagation path, and control information is notified for each of the plurality of grouped slots. <P>SOLUTION: The control information grouping control apparatus controls a control information notification unit of the plurality of slots to be two-dimensionally arranged into the frequency direction and the time direction, using a slot to be defined by a predetermined time length and a predetermined frequency band as a minimum control information notification unit. In this apparatus; a grouping selector 210 inputs a propagation path variation estimating value, and selects a grouping system for grouping the plurality of slots into a control information notification unit consisting of the arrangement of one or more slots in a frequency direction, and one or more slots in a time direction on the basis of the propagation path variation estimating value. <P>COPYRIGHT: (C)2007,JPO&INPIT |
