FIELD: radio engineering, communication.
SUBSTANCE: terminal performance information related to a function of a wireless terminal device in which at least one of a first frequency bandwidth for use in an uplink or a second frequency bandwidth for use in a downlink is variable is made beforehand to correspond to a terminal category. When the terminal performance information is received from the wireless terminal device, the terminal category is specified from the terminal performance information, line setting with the wireless terminal device is carried out and a control signal corresponding to the line setting is transmitted. Control can be simplified by line setting from the terminal category.
EFFECT: high capacity.
