Abstract
A base station (20) and a mobile station (10) preliminarily register a transmission cycle of a CQI associated with every free space, in which channelization codes are not defined in a channelization code set of an HS-SCCH. In the case of setting of the transmission cycle of the CQI, the base station (20) transmits identification information of the free spaces associated with the transmission cycle to be set up to the mobile station (10) by the HS-SCCH. When the identification information of the free space is received by the HS-SCCH, the mobile station (10) transmits the CQI to the base station (20) at the transmission cycle associated with the free space.
