Abstract: This application discloses a multi-link establishment method and a related device. A multi-link association response frame carries radio bitmap information, to indicate an AP allowed to be associated with a radio of a STA MLD or a link allowed to be established by using a radio of a STA MLD, so that the radio subsequently switches between different APs or links. The multi-link association response frame carries link establishment status information, to indicate a link establishment status of each link that the STA MLD requests to establish, so that multi-link establishment is more flexible. The multi-link association response frame carries reassociation information, to indicate whether each parameter in association configuration information is reserved, so that a problem that signaling overheads are relatively large due to a reassociation operation is avoided. It can be learned that, in the multi-link establishment method, the foregoing information is carried to improve multi-link establishment flexibility.

Abstract: This application provides a channel contention method and a related apparatus. The method includes: After data transmission on a first link is completed or a block acknowledgment corresponding to data is received on the first link, a first non-access point station of a first multi-link device performs clear channel assessment CCA detection on a second link in a first time period, where a start moment corresponding to the first time period is the same as a moment at which the data transmission on the first link is completed; and when the CCA detection on the second link fails, the first non-access point station performs channel contention on the second link based on a second time period.

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.
