    • A narrow coverage of a wireless communications system and an access point of the wireless communications system solving a problem about a dead spot, a mobile station and a control method are provided to increase channel use efficiency, cell capacity and throughput due to using MCS(Modulation and Coding Set) of a high level according to a channel situation. A first determining unit(101) of an access point(100) determines that it is necessary to have the electrical transmission of the control messages. A first transmit unit(102) transmits the control messages through a first frequency band. A second transmit unit(104) transmits data message through the second frequency band. A second transmit unit transmits data message through the second frequency band. A third determining unit(106) determines an incumbent user about the first frequency band appeared. A third transmit unit(107) transmits the information about the additional first frequency band which the sensing unit(105) is extracted by the sensing unit through the second frequency band in the mobile station(110). A receiver(108) receives the extracted and additional answer signal through the first frequency band from the mobile station.
    • 提供解决无线通信系统的无线通信系统和无线通信系统的接入点的狭窄覆盖,解决死点,移动台和控制方法的问题,以增加由于使用MCS而导致的信道使用效率,小区容量和吞吐量(Modulation 和编码集)根据信道情况高级别。 接入点(100)的第一确定单元(101)确定需要具有控制消息的电传输。 第一发送单元(102)通过第一频带发送控制消息。 第二发送单元(104)通过第二频带发送数据消息。 第二发送单元通过第二频带发送数据消息。 第三确定单元(106)确定现有用户关于出现的第一频带。 第三发送单元(107)通过移动站(110)中的第二频带发送关于感测单元(105)提取的附加第一频带的信息。 接收机(108)通过来自移动台的第一频带接收提取的和附加的应答信号。
