1. A wireless communication base station comprising:
a plurality of radio units configured to transmit and receive a radio signal; and a digital unit connected to the plurality of radio units via cables and configured to operate a communication protocol, wherein the digital unit controls the plurality of radio units according to a communication environment to be switched into a merge state in which the plurality of radio units forms a cell, or an independent state in which the plurality of radio units forms different cells, respectively, wherein the digital unit has no function of radio communication, wherein the digital unit calculates a channel quality based on a channel quality indicator indicating a quality of a downlink channel or information associated with a quality of an uplink channel and controls the plurality of radio units according to the calculated channel quality; wherein when the plurality of radio units is at the independent state and a channel quality is below a first critical value, the digital unit controls the plurality of radio units to keep the independent state.
