A communication method is applied to a wireless local area network in an enhanced multi-link single radio (EMLSR) mode. When an enhanced multi-link single radio (EMLSR) non-access point multi-link device (non-AP MLD) finds that states of all or some links of the EMLSR non-AP MLD change, the EMLSR non-AP MLD sends a frame on any available link. The frame carries indication information indicating an available link or a link whose state changes in the EMLSR non-AP MLD. Alternatively, the frame may carry another piece of indication information indicating that a state of a link has changed. An access point multi-link device (AP MLD) refrains from sending a signal to the EMLSR non-AP MLD on an unavailable link of the EMLSR non-AP MLD.
