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.
