SEPARATED BASE STATION SYSTEM, NETWORK ORGANIZING METHOD ANDBASEBAND UNIT

摘要

A separated base station system includes: separated baseband units (BBUs) of BSs and separated radio frequency units (RFUs) of BSs, and baseband-radio frequency interfaces provided on the RFUs which are connected with the BBUs and transmit data information. Network organizing method and baseband units for this system are also provided. On the basis of separation of BBUs and RRUs, the capacity of the BBU is further divided, and every unit is separate ly placed. Through enlarged capacity interfaces provided by BBU interface units and the baseband-radio frequency interfaces, network organizing and capacity enlarging of BBUs could be implemented flexibly and conveniently. And at the same time, floor area and operating cost of BS are reduced, and operating reliability of BS is enhanced.
