Abstract

The present invention provides a multi-connectivity communication method and device. The communication method comprises: determining a first message frame in one connection, wherein the first message frame comprises a change sequence field, and a value of the change sequence field is used for indicating quiet information of multiple connections; and sending the first message frame in at least one connection of the multiple connections. The technical solution provided in embodiments of the present invention can reduce signaling overhead, so that the device performs communication in multiple connections, and network throughput is improved.

Claims (26)

1. A multi-link communication method, performed by an access point (AP), the method comprising:

determining a first message frame, wherein the first message frame comprises a change sequence field, and a value of the change sequence field is configured to indicate quiet information for a plurality of links; and

sending the first message frame on at least one link of the plurality of links to at least one station (STA);

wherein the value of the change sequence field is set to a first value, for indicating a change of the quiet information for the plurality of links, the first message frame further comprises quiet time information, and the quiet time information comprises a second link ID, wherein the second link ID corresponds to a link with changed quiet information.

2. The method of claim 1 , wherein the change sequence field is included in a change sequence information element.

3. The method of claim 2 , wherein the change sequence information element comprises: a first link ID, wherein the first link ID corresponds to a link with changed quiet information.

4. The method of claim 1 , further comprising:

sending the quiet time information on the at least one link.

5. The method of claim 1 , wherein the quiet time information comprises a basic service set ID, wherein the basic service set ID corresponds to a link with changed quiet information.

6. The method of claim 1 , wherein the quiet time information comprises a time offset corresponding to a link for sending the quiet time information.

7. The method of claim 1 , wherein the quiet time information comprises: an element ID indicating a type of the quiet time information.

8. The method of claim 1 , further comprising:

sending the quiet time information on at least one link other than the at least one link on which the first message frame is sent; wherein

a format of the quiet time information is the same as a format of a quiet element.

9. A multi-link communication method, performed by a station (STA), the method comprising:

receiving a first message frame on at least one link sent by at least one access point (AP), wherein the first message frame comprises a change sequence field, and a value of the change sequence field is configured to indicate quiet information for a plurality of links; wherein the value of the change sequence field is set to a first value, for indicating a change of the quiet information for the plurality of links, the first message frame further comprises quiet time information, and the quiet time information comprises a second link ID, wherein the second link ID corresponds to a link with changed quiet information.

10. The method of claim 9 , wherein the change sequence field is included in a change sequence information element.

11. The method of claim 10 , wherein the change sequence information element comprises: a first link ID, wherein the first link ID corresponds to a link with changed quiet information.

12. The method of claim 9 , further comprising: receiving the quiet time information on the at least one link.

13. An electronic device comprising:

a processor; and

a memory storing computer programs executable by the processor, wherein when the computer programs are executed by the processor, the method of claim 1 is performed.

14. An electronic device comprising:

a processor; and

a memory storing computer programs executable by the processor, wherein when the computer programs are executed by the processor, the processor is configured to:

receive a first message frame on at least one link sent by at least one access point (AP), wherein the first message frame comprises a change sequence field, and a value of the change sequence field is configured to indicate quiet information for a plurality of links; wherein the value of the change sequence field is set to a first value, for indicating a change of the quiet information for the plurality of links, the first message frame further comprises quiet time information, and the quiet time information comprises a second link ID, wherein the second link ID corresponds to a link with changed quiet information.
