Abstract

The present disclosure provides a communication method and a communication device under multiple links. The communication method may comprise: determining a first message frame, said first message frame comprising a plurality of subframes, each subframe comprising a sender address and a recipient address; said determining a first message frame comprises: according to the capability information of the device sending said first message frame and the device receiving said first message frame, respectively, determining the sender address and recipient address of the subframe under different links accordingly.

Claims (24)

1 . A communication method under multiple links, comprising:

determining a first message frame, wherein the first message frame comprises a plurality of subframes, and each subframe comprises a sender address and a recipient address,

determining the first message frame comprises: based on capability information of a device sending the first message frame and capability information of a device receiving the first message frame, respectively, determining the sender address and the recipient address of a subframe under different links accordingly, wherein the capability information of the device sending the first message frame indicates whether the device is capable of supporting simultaneous sending and/or receiving under multiple links, and the capability information of the device receiving the first message frame indicates whether the device is capable of supporting simultaneous sending and/or receiving under multiple links, and

in response that the device sending the first message frame supports simultaneous sending and/or receiving under multiple links, setting the sender address of the subframe to be different under different links.

2 . The communication method according to claim 1 , further comprising:

setting a capability bit in an extremely high throughput capability element to indicate that a multi-link device supports transmission of the plurality of subframes of the first message frame under multiple links.

3 . The communication method according to claim 1 , further comprising: in response that the device sending the first message frame does not support simultaneous sending and/or receiving under multiple links, setting the sender address of the subframe to be identical under different links.

4 . The communication method according to claim 1 , further comprising: in response that the device sending the first message frame does not support simultaneous sending and/or receiving under multiple links, setting the sender address of the subframe to be different under different links.

5 . The communication method according to claim 1 , further comprising: in response that the device receiving the first message frame supports simultaneous sending and/or receiving under multiple links, setting the recipient address of the subframe to be different under different links.

6 . The communication method according to claim 1 , further comprising: in response that the device receiving the first message frame does not support simultaneous sending and/or receiving under multiple links, setting the recipient address of the subframe to be identical under different links.

7 . The communication method according to claim 1 , further comprising: in response that the device receiving the first message frame does not support simultaneous sending and/or receiving under multiple links, setting the recipient address of the subframe to be different under different links.

8 . The communication method according to claim 1 , further comprising:

in response that neither the device sending the first message frame nor the device receiving the first message frame supports simultaneous sending and/or receiving under multiple links, setting the sender address of the subframe to be identical and the recipient address of the subframe to be identical under each link.

9 . The communication method according to claim 1 , wherein the subframe further comprises a link identifier for identifying a link for sending the first message frame.

10 . The communication method according to claim 9 , wherein the link identifier is set in a padding subfield of the subframe.

11 . The communication method according to claim 9 , wherein the link identifier is set in an MAC header portion of the subframe.

12 . An electronic device, comprising a memory, a processor and a computer program stored on the memory and runnable on the processor, wherein the processor, when executing the computer program, is configured to:

determine a first message frame, wherein the first message frame comprises a plurality of subframes, and each subframe comprises a sender address and a recipient address,

based on capability information of a device sending the first message frame and capability information of a device receiving the first message frame, respectively, determine the sender address and the recipient address of a subframe under different links accordingly, wherein the capability information of the device sending the first message frame indicates whether the device is capable of supporting simultaneous sending and/or receiving under multiple links, and the capability information of the device receiving the first message frame indicates whether the device is capable of supporting simultaneous sending and/or receiving under multiple links, and

in response that the device sending the first message frame supports simultaneous sending and/or receiving under multiple links, set the sender address of the subframe to be different under different links.

13 . A non-transitory computer readable storage medium, having a computer program stored thereon, wherein the computer program, when executed by the processor, causes the processor to:

determine a first message frame, wherein the first message frame comprises a plurality of subframes, and each subframe comprises a sender address and a recipient address,

based on capability information of a device sending the first message frame and capability information of a device receiving the first message frame, respectively, determine the sender address and the recipient address of a subframe under different links accordingly, wherein the capability information of the device sending the first message frame indicates whether the device is capable of supporting simultaneous sending and/or receiving under multiple links, and the capability information of the device receiving the first message frame indicates whether the device is capable of supporting simultaneous sending and/or receiving under multiple links, and

in response that the device sending the first message frame supports simultaneous sending and/or receiving under multiple links, set the sender address of the subframe to be different under different links.
