Abstract: A STA in a STA MLD sends an information frame on a link corresponding to the station, and the information frame is used to indicate a STA in an awake state in the STA MLD. An AP MLD receives the information frame, and sends a downlink message frame on a one or more links corresponding to a part of or all of STAs in the awake state in the STA MLD.

Abstract: This application provides a communications method and a communications apparatus. A first station in a first multi-link device sends first information to a second multi-link device, where the first information is used to indicate a frequency at which how often a station in a power saving mode in the first multi-link device receives a beacon frame. In this way, the second multi-link device may learn about, based on the first information, how often a frequency at which a station in the first multi-link device receives a beacon frame, thereby helping the second multi-link device effectively manage a cache service of each station in the first multi-link device and manage a data buffer space.

Abstract: This application provides a full-duplex communication method and an apparatus. The method includes: when sending a first signal to a first device by using a first transmit sector, receiving, by a third device by using a first receive sector, a second signal sent by a second device. A coverage area of the third device in a receiving direction may be divided into at least one receive sector, the at least one receive sector forms one receive sector group, and the third device may receive the second signal by using the first receive sector that is in the receive sector group and that is different from the first transmit sector. In this way, the third device can simultaneously receive a signal and send a signal by using different sectors, to implement full-duplex transmission, and reduce mutual interference between signal sending and signal receiving, thereby improving communication quality of the full-duplex transmission.
