Abstract: Embodiments of this application relate to the communication field, and in particular, to a multi-link communication method and an apparatus. 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, to assist the part of or all of the stations in fast accessing a channel without waiting for a NAVSyncDelay time period.
