Abstract
A wireless communication system of the present invention achieves improvement of reliability of communication of control data while suppressing the decrease in the communication throughput of data blocks and/or control data. The wireless communication system of the present invention is provided with a base station (1) and a mobile station (2). The mobile station (2) is configured to transmit a plurality of data blocks to the base station (1) at predetermined transmission time intervals. One of the base and mobile stations is configured to generate a plurality of control data used for control of transmission of said plurality of data blocks, to generate a plurality of control messages from said plurality of control data, and to transmit said plurality of control messages to the other of the base and mobile stations. Each of the control data is used for generation of M control messages out of the plurality of control messages, and each of the control messages is generated from M control data out of the plurality of control data.
