Abstract
Embodiments of the present invention provide a method and a device for accessing a channel. The method includes: receiving a contention request frame transmitted by a first transmitting end device on M sub-carriers, where the M sub-carriers at least have two inconsecutive sub-carriers, and the contention request frame is modulated onto the M sub-carriers; according to the contention request frame, acquiring channel state information about the first transmitting end device respectively on the M sub-carriers, and determining channel state information about the first transmitting end device respectively on N sub-carriers, where the N sub-carriers are obtained by dividing all or a part of a system available frequency band, the N sub-carriers include the M sub-carriers, both N and M are positive integers, N>M and M>1; and performing allocation of a transmission sub-channel according to the channel state information about the first transmitting end device respectively on the N sub-carriers.
