Abstract: This application provides a channel access method and an apparatus, and relates to the field of communication technologies, to resolve a problem that it is difficult for a long range communication device to access a channel, and communication efficiency is low. The method includes: A first device detects a channel status in first duration. If a channel is in an idle state, M is subtracted from a value of a first counter, where M is a positive integer greater than 1. If the value of the first counter is greater than 0, the first device detects the channel status in next first duration; or if the value of the first counter is less than or equal to 0, the first device transmits data through the channel.

Abstract: A communication method includes a first communication device that sends, to a second communication device, a physical layer protocol data unit (PPDU) including indication information and M link adaptation blocks, where the indication information indicates a resource used for link adaptation, the M link adaptation blocks use different transmission parameters, and the resource is used to transmit the M link adaptation blocks. The second communication device returns, to the first communication device, a feedback result determined based on a measurement result corresponding to the M link adaptation blocks, so that the first communication device sends, based on the feedback result, a PPDU used for data transmission. Hence, the two communication devices complete link adaptation through one interaction, and do not need to perform a plurality of interactions.

Abstract: In a communication method, a first access point (AP) in a first AP multi-link device generates a management frame that includes a capability information field. The capability information field includes first indication information indicating whether a second AP, which is also in the first AP multi-link device, has performed a channel switch. The first AP then sends the management frame to a first station (STA).
