Embodiment Construction
[0026] The present invention is suitable for figure 1 The central network shown in the scene includes the secondary user SU and the secondary user base station CBS; the secondary user SU and the secondary user base station CBS are connected wirelessly, and the secondary user base station CBS allocates spectrum to the secondary user; the secondary user SU and the secondary user base station CBS The information transmission between user base stations CBS is carried out on the control channel, and the information between the secondary users SU is transmitted through the data channel; the traditional single control channel is converted into multiple control channels by using segmentation technology, because the bandwidth required for control information is relatively small , according to the actual situation, the traditional single control channel can be divided into control channels and some data channels that meet the needs. The secondary user base station CBS dynamically adju...
