Abstract
In a radio communication system that simultaneously provides communication service using a plurality of discontinuous frequency bands, a multi-band radio communication method according to the present invention is a method in which a base station constituting the system allocates a band to a mobile station that requests a communication starting. For example, a specific receiving unit within the base station extracts control information concerning a channel state in each of the frequency bands, and recognizes a frequency band in which the mobile station can receive information, from a result of the extraction. A channel controller 9 determines, starting from a high frequency band, whether a new traffic responding to the communication starting request can be allocated in each frequency band.

43. A multi-band radio communication method for a base station that allocates a bandwidth to a mobile station which requests initiation of communication, the base station constituting a radio communication system that simultaneously provides communication services through a plurality of discontinuous frequency bands, the multi-band radio communication method comprising:
-
extracting control information related to channels in each of the frequency bands; identifying bandwidths at which the mobile station can communicate based on the control information; and determining, in a predetermined order, whether each of the bandwidths is available for new traffic corresponding to requested communication. - View Dependent Claims (44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 79, 80, 81, 82)

68. A multi-band radio communication method applied to a radio communication system that includes a mobile station that issues a request for initiation of communication and a base station that allocates a bandwidth to the mobile station in response to the request, and that simultaneously provides communication services through a plurality of discontinuous frequency bands, the multi-band radio communication method comprising:
-
the mobile station transmitting the request through a first frequency band; the base station determining whether the first frequency band is available for new traffic, and, when the first frequency band is available, allocating a channel to the mobile station; the mobile station checking availability of frequency bands other than the first frequency band; and the base station shifting traffic of the mobile station to a second frequency band based on the availability of frequency bands. - View Dependent Claims (69, 70, 71, 72, 73)
