A method and apparatus for multi-link communication
By sending information frames in multi-link devices to indicate wake-up status, the AP or STA sends downlink message frames on the corresponding link, which solves the latency and power consumption problems caused by the lack of channel status information, and achieves fast channel access and energy saving.

Abstract
This application relates to the field of communications, and more particularly to a multi-link communication method and apparatus. This application provides a multi-link communication method and apparatus in which a STA in a STA MLD transmits an information frame on the link corresponding to the site. The information frame indicates that the STAs in the STA MLD are in a wake-up state. An AP MLD receives the information frame and transmits downlink message frames on the links corresponding to some or all of the STAs in the STA MLD that are in a wake-up state. This assists some or all of the sites in quickly accessing the channel without waiting for the NAVSyncDelay time, thereby improving the timeliness of wake-up STAs accessing the channel and saving power consumption of the wake-up STAs.
