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).

Abstract: This application discloses communication methods and apparatuses. In an example method, a physical layer protocol data unit (PPDU) is generated and sent. The PPDU includes multiple resource unit allocation subfields. The multiple resource unit allocation subfields include a resource unit allocation subfield corresponding to a multiple resource unit (MRU) to indicate that a 242-tone resource unit (RU) corresponding to the resource unit allocation subfield belongs to the MRU. A number of resource unit allocation subfields corresponding to the MRU in a resource unit allocation subfield corresponding to each 80 MHz subblock in a bandwidth for transmitting the PPDU is for determining or indicating a type of the MRU. A station can determine, based on the number of resource unit allocation subfields corresponding to the MRU in the resource unit allocation subfield corresponding to each 80 MHz subblock, which type of MRU is included in the bandwidth for transmitting the PPDU.
