    • In a wireless communication system, a terminal is identified by a base station in accordance with beacon signals transmitted periodically from the base station, and to the identified terminal, the presence or absence of data to be transmitted and a period until a transmission of a next beacon signal are notified. A terminal-side wireless communication section in the terminal transmits, to the base station, a request for setting of a period between transmissions of beacon signals. A communication control section in the base station sets the period between transmissions of beacon signals in accordance with the request having been received from the terminal. With this arrangement, the terminal can optimize its period between receptions of beacon signals, thereby keeping OFF power supply to a communication circuit from a power source section until the timing for receiving a beacon signal. This allows the terminal to reduce its power consumption.
    • 在无线通信系统中,终端由基站根据从基站周期性地发送的信标信号和所识别的终端识别要发送的数据的存在或不存在以及下一个发送的时间段 通知信标信号。 该终端中的终端侧无线通信部向基站发送对信标信号的发送之间的周期的设定的请求。 基站中的通信控制部根据从终端接收到的请求,设定信标信号的发送间隔。 通过这种布置,终端可以优化其在信标信号的接收之间的周期,从而保持关闭从电源部分到通信电路的电源,直到接收信标信号的定时。 这允许终端降低功耗。
