METHOD AND APPARATUS FOR EVALUATING CHANNEL AVAILABILITY OF STATION

摘要

The present invention provides a method and apparatus for evaluating channel availability of a station. The method includes that: determining at least one first bandwidth mode supported by a station that needs to transmit data and at least one second bandwidth mode supported by the target device of the data transmission (210); according to at least one first bandwidth mode and at least one second bandwidth mode, determining at least one candidate bandwidth mode used for data transmission (220); determining the availability judging parameter and corresponding threshold of a first candidate bandwidth mode which is any one of at least one candidate bandwidth modes (230); according to the availability judging parameter and corresponding threshold, determining the availability of the first candidate bandwidth mode (240); according to the available first candidate bandwidth mode, determining the bandwidth mode used by the station for data transmission (250). When the present invention is used for evaluating channel availability, the station can avoid over protection to data transmission bandwidth having been set up and is able to use bandwidth resource reasonably and increase system throughput.
