MOBILE STATION DEVICE, BASE STATION DEVICE, COMMUNICATION METHOD, INTEGRATED CIRCUIT, AND COMMUNICATION SYSTEM

摘要

The present invention enables the efficient transmission/reception of a signal containing control information between a base station device and a mobile station device. To achieve this, the present invention has a control unit such that second elements are configured from resources resulting from splitting a single physical resource block pair, first elements are configured from at least one of the second elements, a control channel is configured from a collection of at least one of the first elements, and any one of the first elements and one or more of the second elements are associated.
