Title:
Radio communication equipment and a channel selection method
Document Type and Number:
Japanese Patent JP6251047
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To perform frequency dispersion communication for improving frequency use efficiency.SOLUTION: A radio communication device comprises: a use channel detection unit for repeatedly performing processing of determining, using carrier sensing, whether each lump of a plurality of channels is being used or not to store a combination of unused channels in a storage unit; an availability frequency calculation unit for calculating a frequency of having obtained transmission opportunities for each combination of channels simultaneously available to the device, on the basis of a frequency of detecting a combination of unused channels stored in the storage unit; and a use channel selection unit for selecting a combination of channels corresponding to the maximum frequency of frequencies calculated by the availability frequency calculation unit as a combination of channels to be used in the device.
