摘要

PROBLEM TO BE SOLVED: To reduce the amount of information transmitted from BBU to RRU.SOLUTION: The present invention stores fixed data in a RRU, adds the data together with varying data upon reception from a BBU and transmits the added data as a radio signal. Thus, the fixed data is not required to be transmitted from the BBU to the RRU; therefore, the amount of information transmitted from the BBU to the RRU can be reduced.
