INTER-STATION TRANSMISSION METHOD, RADIO BASE STATION MONITORING METHOD, AND DEVICE USING THE METHOD

摘要

There is provided a new inter-station transmission method capable of prolonging the time assigned to a transmission path delay of the inter-station transmission path in a predetermined turn around time as compared to the conventional method, and increasing the inter-station transmission distance as much as possible. A radio base station (20) reproduces a clock synchronized with a BSU transmission clock DCLK used when transmitting the downlink transmission data by a communication control station (10). According to the clock reproduced, the radio base station (20) processes the downlink transmission data. This clock synchronization eliminates the need of data format conversion between the communication control station (10) and the radio base station (20). Accordingly, there is no need of a buffer such as a FIFO for accumulating the transfer data for conversion preparation. Consequently, it is possible to reduce the delay time caused by the buffer in the conventional process. This can reduce the turn around time of the mobile communication system. When this is used in a narrow band communication where the turn around time is fixed, it is possible to increase the physical distance between the communication control station and the radio base station by the delay time which has been reduced.
