Abstract

A data transmission method includes: generating, by a terminal, a multi-link target wakeup time (TWT) data frame based on one link, the TWT data frame including a baseline TWT and a plurality of TWT offsets with respect to the baseline TWT; and sending, by the terminal, the TWT data frame.

Claims (38)

1 . A data transmission method, comprising:

generating, by a terminal, a multi-link target wakeup time (TWT) data frame based on one link, the multi-link TWT data frame comprising a baseline TWT and a plurality of TWT offsets with respect to the baseline TWT, the plurality of TWT offsets correspond to a plurality of bands; and

sending, by the terminal, the multi-link TWT data frame;

wherein the baseline TWT is determined based on parameter information of a time synchronization function (TSF) of a first link; and the first link is one of a plurality of links.

2 . The data transmission method according to claim 1 , wherein the multi-link TWT data frame further comprises an identification bit, the identification bit being configured for identifying that the multi-link TWT data frame is a TWT data frame for indicating performing a multi-link operation.

3 . The data transmission method according to claim 1 , wherein the multi-link TWT data frame further comprises a plurality of band identifications, and each of the plurality of band identifications corresponds to a TWT offset of the TWT offsets, respectively.

4 . The data transmission method according to claim 1 , wherein the first link is a link establishing an initial association among the plurality of links.

5 . The data transmission method according to claim 1 , wherein sending the multi-link TWT data frame comprises:

sending the multi-link TWT data frame based on a trigger frame by unicasting through the first link.

6 . The data transmission method according to claim 1 , wherein sending the multi-link TWT data frame comprises:

sending the multi-link TWT data frame based on a beacon frame by broadcasting through the first link.

7 . A non-transitory computer-readable storage medium, wherein instructions in the storage medium, when executed by one or more processors of a terminal, cause the terminal to perform the data transmission method according to claim 1 .

8 . A data transmission method, comprising:

receiving, by a terminal, a multi-link target wakeup time (TWT) data frame, the multi-link TWT data frame being generated based on one link and comprising a baseline TWT and a plurality of TWT offsets with respect to the baseline TWT, the plurality of TWT offsets correspond to a plurality of bands; and

receiving, by the terminal, data based on the baseline TWT and the plurality of TWT offsets;

wherein the baseline TWT is determined based on parameter information of a time synchronization function (TSF) of a first link; and the first link is one of a plurality of links.

9 . The data transmission method according to claim 8 , wherein the multi-link TWT data frame further comprises an identification bit, the identification bit being configured for identifying that the multi-link TWT data frame is a TWT data frame for indicating performing a multi-link operation.

10 . The data transmission method according to claim 8 , wherein the multi-link TWT data frame further comprises a plurality of band identifications, and each of the plurality of band identifications corresponds to a TWT offset of the TWT offsets, respectively.

11 . The data transmission method according to claim 8 , wherein the first link is a link establishing an initial association among the plurality of links.

12 . The data transmission method according to claim 8 , wherein receiving the multi-link TWT data frame comprises:

receiving a trigger frame through the first link, and receiving the multi-link TWT data frame based on the trigger frame.

13 . The data transmission method according to claim 8 , wherein receiving multi-link the TWT data frame comprises:

receiving a beacon frame through the first link, and receiving the multi-link TWT data frame based on the beacon frame.

14 . A data transmission apparatus, comprising:

one or more processors; and

a memory, configured to store processor-executable instructions; wherein

the one or more processors are configured to: execute the data transmission method according to claim 8 .

15 . A non-transitory computer-readable storage medium, wherein instructions in the storage medium, when executed by one or more processors of a terminal, cause the terminal to perform the data transmission method according to claim 8 .

16 . A data transmission apparatus, comprising:

one or more processors; and

a memory, configured to store processor-executable instructions; wherein

the one or more processors are configured to:

generate a multi-link target wakeup time (TWT) data frame based on one link, the multi-link TWT data frame comprising a baseline TWT and a plurality of TWT offsets with respect to the baseline TWT, the plurality of TWT offsets correspond to a plurality of bands; and

send the multi-link TWT data frame;

wherein the baseline TWT is determined based on parameter information of a time synchronization function (TSF) of a first link; and the first link is one of a plurality of links.

17 . The data transmission apparatus according to claim 16 , wherein the first link is a link establishing an initial association among the plurality of links.

18 . The data transmission apparatus according to claim 16 , the one or more processors are configured to: send the multi-link TWT data frame based on a trigger frame by unicasting through the first link; or

send the multi-link TWT data frame based on a beacon frame by broadcasting through the first link.
