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 demodulation reference signal (DMRS) configuration method, a network device sends first scheduling information to a terminal device. The terminal device determines, based on the first scheduling information, whether a transmission of a first time unit meets a condition of having the same transmit power, same precoding, same antenna port, or a same frequency domain resource as the transmission of a second time unit. The second time unit is before the first time unit and has a transmission direction that is the same as a transmission direction in the in the first time unit, and no transmission in an opposite direction exists between the second time unit and the first time unit. When the first time unit meets the above condition, the terminal device sends uplink data in the first time unit and the second time unit, or receiving downlink data in the first time unit and the second time unit.

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).
