Abstract: This application relates to the field of wireless fidelity technologies, and in particular, to a channel access method and a communication apparatus. The method includes: A first access point sends a management frame to a first device, where the management frame includes first indication information, the first indication information indicates at least one first reserved resource that first traffic is allowed to contention-based access, and the at least one first reserved resource only includes a time-frequency resource; and then the first device initiates channel access on the at least one first reserved resource, and transmits the first traffic. Because the at least one first reserved resource is specially reserved for the first traffic, it may be considered that traffic other than the first traffic does not contention-based access the at least one first reserved resource.
