Embodiment Construction
[0019] refer to figure 1 , figure 2 , The present invention includes 1. Comprehensive utilization of various time slot channels under the cooperation of frame plan, 2. Determination of synchronization control mode, 3. Initial acquisition design, 4. Synchronization maintenance design.
[0020] Multi-carrier frame structure such as figure 2 as shown, figure 2 It is a schematic diagram of the multi-carrier frame structure of the present invention. The system sets free data time slots in the data time slots of each carrier. If the business station has no business transmission on the on-duty carrier of the station for a long time, the master station will regularly allocate a free data time slot channel for it. After the service station obtains the free data time slot channel, if there is non-real-time service transmission, it can transmit service data; if there is no service data transmission, it will send dummy data. In the present invention, the station with self-transmis...
