Abstract: This application provides a wake-up method, a station, and an access point. The method is performed in a communications system. The communications system can include an access point (AP) and at least one station (STA). The AP includes a wake-up transceiver (WUR) and a main transceiver. The method can include determining, by a first STA, that the AP is in a sleep state, where when the AP is in the sleep state, the main transceiver of the AP is in an off state. The method can also include transmitting, by the first STA, a wake-up frame to the WUR of the AP, where the wake-up frame triggers the WUR of the AP to wake up the main transceiver of the AP. Therefore, an uplink data transmission latency can be reduced.

Abstract: Embodiments of this application provide a multi-link communication method, an apparatus, and a system that relate to the field of communication technologies, to resolve a technical problem in conventional multi-link communication that an amount of information sent by a multi-link device to a peer multi-link device is large, a process in which the peer multi-link device determines, based on the information, a link that can support simultaneous data sending and receiving as a link that is receiving data is cumbersome, and processing load of the peer multi-link device is heavy. The method includes: generating link grouping information, where the link grouping meets a following characteristic: links belonging to different link groups support simultaneous data sending and receiving; and sending the link grouping information.

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.
