Terminal device performance information related to a function of a wirele ss terminal device in which at least either a first frequency band width use d for the up line or a second frequency band width used for the down line is variable is made beforehand to correspond to a terminal device category. In the case where the terminal device performance information is received from the wireless terminal device, the terminal device category is specified fro m the terminal device performance information. On the basis of the specified terminal device category, line setting with the wireless terminal device is carried out and a control signal corresponding to the line setting is trans mitted. The line setting along the terminal device category is carried out, so that control is simplified. |
