PROBLEM TO BE SOLVED: To provide a distributed radio communication base station system and a distributed radio communication base station communication method that can correctly demodulate a signal of any radio terminal and prevent the occurrence of spurious even if required bandwidth exceeds communication capacity between a base band unit (BBU) and a remote radio unit (RRU).SOLUTION: The invention suppresses power of a radio signal at any frequency band (applies frequency axis band restriction) for the signal transmitted between a base band unit (BBU) and a remote radio unit (RRU), reduces a sampling frequency, thereby makes required bandwidth at or less than communication capacity between the BBU and the RRU. |
