Abstract: <P>PROBLEM TO BE SOLVED: To provide a wireless communication system that not only prevents interference but also maintains the preferred communication quality.  <P>SOLUTION: A mobile station becomes ready for receiving transmission authorization data from a base station when data for requesting a transmission right including a mobile station (ID) for identifying its own station in response to a transmission operation is transmitted. The mobile station transits to the state for transmitting data when the mobile station (ID) included in the received transmission authorization data coincides with its own mobile station (ID), but it transits to the state for receiving data when the mobile station (ID) included in the transmission authorization data does not coincide with its own mobile station (ID). The base station discards the received data for requesting transmission right if there is a mobile station having the transmission right when data for requesting the transmission right transmitted from the mobile station is received. If there is not the mobile station having the transmission right, transmission authorization data covering the mobile station (ID) included in the received data for requesting transmission right is generated for transmission.  <P>COPYRIGHT: (C)2009,JPO&INPIT
