The frequency band controlling part 107 selects a frequency band for the transmission line and a frequency band for the reception line for the base station 200 according to this assignable frequency band contained in the control signal.
CROSS REFERENCE TO RELATED APPLICATION This application is based upon and claims the benefit of priority from the prior Japanese Patent Application No. P2001-258586, filed on Aug. 28, 2001; the entire contents of which are incorporated herein by reference.
BRIEF SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a communication channel setting method, a communication controller, and a radio communication system each of which can contribute to enhancing frequency utilization efficiency.
BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS FIG. 1 is a view illustrating assignment processing for assigning communication channels in a conventional radio communication system;
DETAILED DESCRIPTION OF THE INVENTION The present invention can be applied to a radio communication system that performs communication between base stations providing communication services with respect to, for example, portable terminal devices.
In the radio communication system configured in the above-described way, when performing communication between the base station 100 and the base station 200, a radio line used for transmission from the base station 100 to the base station 200 (referred to as �the transmission line� for convenience of explanation) and a radio line used for transmission from the base station 200 to the base station 100 (referred to as �the reception line� for convenience of explanation) are set as the communication channels according to the prescribed procedures carried out between the frequency band controlling part 107 and the frequency band controlling part 207. Thereafter, communications start between the both base stations.
Meanwhile, the frequency and bandwidth (hereinafter referred to simply as �the frequency band�) for the transmission line at the step S5 in FIG. 5 are selected based on the assignable frequency band for the transmission line which can be determined by the frequency, bandwidth and the power of the interference wave, the bandwidth of the transmission line, and the frequency band of the reception line. Several methods of selecting the frequency band for the radio line can be considered, as is shown below.
