Abstract
Provided is a wireless communication device which is capable of suppressing an increase in communication interference in wireless communication over a backhaul line, even if the number of installed wireless communication devices is increased. The wireless communication device communicates with a different wireless communication device over a wireless backhaul line in which a plurality of wireless communication schemes are mixed and used. The wireless communication device sets an initial value of transmission power related to data communication with the different wireless communication device, based on information on usage history of transmission power related to the data communication with the different wireless communication device.

A wireless communication base station, which communicates with a different wireless communication base station over a wireless backhaul line in which a plurality of wireless communication schemes are mixed and used, comprising:
- a processor that,
- allocates a radio frequency to establish the wireless backhaul line over which to communicate with the different wireless communication base station,
- prior to commencing data communication with the different wireless communication base station, sets an initial value of transmission power related to the data communication with the different wireless communication base station at the allocated radio frequency, based on information on usage history of transmission power related to the data communication with the different wireless communication base station, wherein the information on usage history includes a record of transmission power used in prior data communication with the different wireless communication base station;
- and
- an antenna that performs data communication with the different wireless communication base station, based on the set initial value of transmission power,
- wherein, the processor, in operation,
- performs transmission power control to adjust the transmission power during the data communication based on information on reception power notified from the different wireless communication base station;
- and
- updates the information on usage history of transmission power at the allocated radio frequency based on information on the transmission power used for the data communication.
A transmission-power setting method of a wireless communication base station, which communicates with a different wireless communication base station over a wireless backhaul line in which a plurality of wireless communication schemes are mixed and used, the method comprising:
- allocates a radio frequency to establish the wireless backhaul line over which to communicate with the different wireless communication base station;
- setting, prior to commencing data communication with the different wireless communication base station, an initial value of transmission power related to the data communication with the different wireless communication base station at the allocated radio frequency, based on information on usage history of transmission power related to the data communication with the different wireless communication base station, wherein the information on usage history includes a record of transmission power used in prior data communication with the different wireless communication base station;
- performing data communication with the different wireless communication base station, based on the set initial value of transmission power;
- performing transmission power control to adjust the transmission power during the data communication based on information on reception power notified from the different wireless communication base station;
- and
- updating the information on usage history of transmission power at the allocated radio frequency based on information on the transmission power used for the data communication.
