Abstract

The present invention enables efficient transmission/reception of a signal including control information between a base station apparatus and a mobile station apparatus. To realize this, second elements are formed using resources that are obtained by dividing one physical resource block pair, each of first elements is constituted by one or more of the second elements, a control channel is constituted by an aggregation of one or more of the first elements, and there is provided a controller that associates any one of the first elements with one or a plurality of the second elements.

Claims
