The present invention discloses a channel resource allocation method and a communications device. The method includes: acquiring, by a first device, scheduling information from an access point; and if the first device is pre-scheduled by the access point according to the scheduling information to receive data from a second device in a first timeslot of a first channel, and before a start moment of data transmission time corresponding to the first timeslot of the first channel, sending, by the first device, a contention frame to contend for the first timeslot of the first channel. In the present invention, a scheduling mode and a contention mode are combined, the access point may first perform pre-scheduling on the first device, and before a start moment at which data transmission is performed in a corresponding timeslot, the first device sends the contention frame according to the scheduling information to contend for a use right of the channel, which reduces a quantity of potential contention devices and improves efficiency. The present invention provides a method for introducing a scheduling mode into a communications system that uses an unauthorized frequency spectrum. |
