BASE STATION AND METHOD FOR DETERMINING UNLICENSED FREQUENCY CANDIDATE

摘要

A base station includes a storage device to store results of carrier sensing performed respectively on a data transmission side and on a data reception side with respect to a plurality of sub-bands in unlicensed frequencies being the frequencies of which a use is not licensed for data transmission, and a controller to extract sub-bands of the unlicensed frequencies being determined that are in an idle status or have high possibility to be in the idle status by both of the data transmission side and the data reception side in the carrier sensing results as candidates for sub-bands of the unlicensed frequencies to be used for transmitting data by the data transmission side.
