RADIO COMMUNICATION TERMINAL, METHOD FOR SELECTING COMMUNICATION CHANNEL AND COMPUTER-READABLE STORAGE MEDIUM
First Claim
1. A radio communication terminal, comprising:
- a communication unit which communicates using at least one channel in a first frequency band;
a channel investigating unit which investigates all channels in said first frequency band, detects an available channel in said all channels and outputs a detection result as available channel information; and
a channel setting unit which receives said available channel information, determines whether or not a plurality of channels adjacent to each other in said first frequency band are available for communication based on said available channel information, and sets a plurality of channels which are not adjacent to each other in said communication unit as channels which are available for communication in said first frequency band when it is determined that said plurality of channels adjacent to each other are not available for communication.

Abstract
A radio communication terminal includes a communication unit, a channel investigating unit and a channel setting unit. The communication unit communicates using at least one channel in a first frequency band. The channel investigating unit investigates all channels in the first frequency band, detects an available channel in the all channels and outputs a detection result as available channel information. The channel setting unit receives the available channel information, determines whether or not a plurality of channels adjacent to each other in the first frequency band are available for communication based on the available channel information.

17. A channel selecting method in a radio communication terminal which communicates using at least one channel in a first frequency band, comprising:
-
investigating all channels in said first frequency band, detecting an available channel in all channels and creating available channel information; determining whether or not a plurality of channels which are adjacent to each other in said first frequency band are available for communication based on said available channel information; and setting a plurality of channels which are not adjacent to each other as channels to be used for communication in said first frequency band when it is determined that said plurality of channels which are adjacent to each other cannot be used for communication. - View Dependent Claims (18, 19, 20)

21. A channel selecting method in a radio communication terminal which communicates not only using at least one channel in a first frequency band but also using at least one channel in a second frequency band, comprising:
-
investigating all channels in said first and said second frequency bands, detecting an available channel in said all channels and creating available channel information; determining whether or not a plurality of channels which are adjacent to each other in one frequency band are available for communication based on said available channel information; and setting a plurality of channels which are not adjacent to each other in said one frequency band as channels to be used for communication, when it is determined that said plurality of channels which are adjacent to each other in said one frequency band of said first and said second frequency bands cannot be used for communication. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)

29. A computer-readable storage medium which stores instructions to enable a computer to carry out a channel selecting method installed in a radio communication terminal which communicates using at least one channel in a first frequency band, wherein
said method, comprising: -
investigating all channels in said first frequency band, detecting an available channel in all channels and creating available channel information; determining whether or not a plurality of channels which are adjacent to each other in said first frequency band are available for communication based on said available channel information; and setting a plurality of channels which are not adjacent to each other as channels to be used for communication in said first frequency band when it is determined that said plurality of channels which are adjacent to each other cannot be used for communication.

30. A computer-readable storage medium which stores instructions to enable a computer to carry out a channel selecting method installed in a radio communication terminal which communicates not only using at least one channel in a first frequency band but also using at least one channel in a second frequency band, wherein
said method, comprising: -
investigating all channels in said first and said second frequency bands, detecting an available channel in said all channels and creating available channel information; determining whether or not a plurality of channels which are adjacent to each other in one frequency band are available for communication based on said available channel information; and setting a plurality of channels which are not adjacent to each other in said one frequency band as channels to be used for communication, when it is determined that said plurality of channels which are adjacent to each other in said one frequency band of said first and said second frequency bands cannot be used for communication.

31. A radio communication terminal, comprising:
-
communication means for communicating using at least one channel in a first frequency band; channel investigating means for investigating all channels in said first frequency band, detecting an available channel in all channels, and outputting said detection result as available channel information; and channel setting means for receiving said available channel information, determining whether or not a plurality of channels which are adjacent to each other in said first frequency band can be used for communication based on said information and setting a plurality of channels which are not adjacent to each other as a channel to be used for communication in said first frequency band when it is determined that a plurality of channels adjacent to each other can not be used for communication.
