METHOD AND APPARATUS FOR ACCESSING BROADBAND CHANNEL IN WIRELESS LAN SYSTEM

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a backoff procedure and an apparatus therefor for efficiently performing a wideband channel connection in a wireless LAN system.To this end, the station performs a CCA (Clear Channel Assessment) operation in each of a plurality of channels, and one or more channels of a plurality of channels are not used, and the at least one channel is a frame in a BSS And the backoff procedure is performed or retried in the at least one channel when the at least one channel is not used for transmission. If the backoff counter value becomes zero according to the backoff procedure, the station may transmit the frame over the one or more channels.
