Abstract
A base station device includes: a control information generating section which generates control information specific to mobile station devices; a control information count indicator generating section which generates a control information count indicator indicating the number of pieces of generated control information of each mobile station device; and a transmitting section which transmits the control information count indicator and the control information. The mobile station device includes: a receiving section which receives a control information count indicator and control information transmitted from the base station device within a mobile station-specific search space selected based on a mobile station ID of the mobile station device; a control information count indicator detecting section which detects the control information indicator; and a control channel decoding section which decodes the control channel in response to the number of pieces of detected control information.
