1. A multi-link communication method, comprising:
receiving, by a first access point in an access point multi-link device (AP MLD) from a first station in a station multi-link device (STA MLD), an information frame on a first link corresponding to the first station, wherein the information frame indicates a second station that is to send an uplink service and that loses channel state information, and wherein the second station is comprised in the STA MLD;
sending, by a second access point in the AP MLD to the second station, a downlink message frame on a second link corresponding to the second station, wherein the downlink message frame is configured to be used to assist the second station in sending the uplink service, and wherein the STA MLD does not support simultaneous transmitting and receiving; and
receiving, by the second access point, the uplink service on the second link.
