    • A cognitive radio base station may transmit, for each channel, common control channel information to a plurality of cognitive radio terminals at different points in time, respectively. Accordingly, the cognitive radio base station may receive a channel allocation request from the plurality of cognitive radio terminals receiving the common control channel information and allocate a plurality of channels to the plurality of cognitive radio terminals, respectively, to perform communication. In response to another terminal existing in a corresponding channel, the cognitive radio base station may update the common control channel information and switch to another channel to transmit subsequent common control channel information at, for example, a closest point in time to thereby broadcast the updated common control channel information to the plurality of cognitive radio terminals using the switched channel.
    • 认知无线电基站可以分别在不同的时间点向每个信道发送公共控制信道信息给多个认知无线电终端。 因此,认知无线基站可以从接收公共控制信道信息的多个认知无线终端接收信道分配请求,并分别向多个认知无线终端分配多个信道,以进行通信。 响应于相应信道中存在的另一个终端,认知无线电基站可以更新公共控制信道信息并切换到另一个信道以在例如最近的时间点发送后续公共控制信道信息,从而广播更新的 使用切换信道的多个认知无线电终端的公共控制信道信息。
