Radio resources are saved. The base station 101 determines a possibility of transmitting data to the terminal 102, and transmits the indicator indicating the possibility of transmitting the data to the terminal 102. The terminal 102 generates a mode request message for determining a coding rate and a modulation system at the base station 101, and sets a transmission frequency of the mode request message based on the indicator transmitted from the base station 101. Accordingly, the mode request message is transmitted from the terminal 102 to the base station 101 at the determined transmission frequency.

节省了无线资源。基站101判定把数据发送至终端102的可能性,并把表明发送数据可能性的标识发送至终端102。终端102生成模式请求消息,用来判定基站101处的编码率和调制方式,并基于从基站101发送的标识,来设定模式请求消息的发送频率。于是,模式请求消息即以预定义的发送频率从终端102发送至基站101。
