Abstract
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.
Claims20
A link state indication method, comprising:
- generating, by a non-access point multi-link device (non-AP MLD), a third frame, wherein the third frame comprises:
- third indication information and fourth indication information, wherein the third indication information indicates that a state of a link of the non-AP MLD changes and that the non-AP MLD supports an enhanced multi-link single radio (EMLSR) mode, and wherein the fourth indication information indicates an available link or a link whose state changes in the non-AP MLD;
- and
- sending, by the non-AP MLD, the third frame.
A communication apparatus, comprising:
- one or more processors configured to generate a third frame, wherein the third frame comprises:
- third indication information and fourth indication information, wherein the third indication information ndicates that a state of a link of the non-AP MLD has changed and that the non-AP MLD supports an enhanced multi-link single radio (EMLSR) mode, and wherein the fourth indication information indicates an available link or a link whose state changes in a non-access point multi-link device (non-AP MLD);
- and
- a transceiver configured to send the third frame.
A computer-program product comprising instructions that are stored on a non-transitory storage medium and that, when executed by one or more processors, cause an apparatus to:
- generate, using a non-access point multi-link device (non-AP MLD), a third frame, wherein the third frame comprises:
- third indication information and fourth indication information, wherein the third indication information indicates that a state of a link of the non-AP MLD changes, and that the non-AP MLD supports an enhanced multi-link single radio (EMLSR) mode, and wherein the fourth indication information indicates an available link or a link whose state changes in the non-AP MLD;
- and
- send, using the non-AP MLD, the third frame.
