Wireless communication method and wireless communication apparatus

A wireless communication device comprising:

• among a signal processing function and a communication function provided by a wireless communication device, a centralized unit having the signal processing function,
• and two or more radio units having the communication function connected with the centralized unit via optical fiber;
• and wherein,
• the centralized unit transmits an optical signal having a form corresponding to the downstream radio signal to be transmitted by the communication function, to a communication target radio unit which communicates with an external communication device, among two or more radio units having the communication function connected with the centralized unit via optical fiber,
• and performs beamforming control of the communication target radio unit;
• and the communication target radio unit communicates with the external communication device according to the control of the centralized unit.
