setting, in response to the first station supporting multi-link sending and receiving and the second station supporting multi-link sending or multi-link receiving, the waiting time as a frame length for data transmission between the access point and the second station in the second link; or
setting, in response to the first station supporting multi-link sending and receiving and the second station supporting single-link sending or single-link receiving, the waiting time as a frame length for data transmission between the access point and the second station in the second link.
5. The method according to claim 3 , wherein determining the time information according to the information of capability of the first station and the information of capability of the second station comprises:
setting, in response to the first station supporting multi-link sending and receiving and the second station supporting multi-link sending and receiving, the waiting time as zero.

a probe request frame, an association request frame and an authentication request frame.
7. The method according to claim 1 , wherein the information of capability comprises one of:
a first value indicating that a corresponding station supports multi-link sending and receiving;
a second value indicating that a corresponding station supports multi-link sending or multi-link receiving; or
a third value indicating that a corresponding station supports single-link sending or single-link receiving.
8. The method according to claim 1 , wherein
transmission of the second data frame between the access point and the second station in the second link comprises at least one of:
receiving the second data frame sent by the second station in the second link; and
sending the second data frame to the second station in the second link connection.
9. The method according to claim 1 , wherein a basic service set identifier (BSSID) carried in the first data frame is the same as a BSSID carried in the second data frame; or, a basic service set (BSS) color carried in the first data frame is the same as a BSS color carried in the second data frame.
10. A non-transitory computer storage medium storing a computer-executable instruction, the computer-executable instruction being capable of implementing the method according to claim 1 when being collectively executed by one or more processors.
11. A method for indicating data transmission under multi-links, performed by a first station and comprising:
sending a first data frame in a first link;
receiving an acknowledgement message frame for the first data frame in the first link, the acknowledgement message frame containing time information, and the time information being configured to indicate time at which the first station accesses the first link after receiving the acknowledgement message frame; and
accessing the first link according to the time information;
wherein the method further comprises:
sending information of capability of the first station to an access point, the information of capability of the first station being used for determining the time information.
12. The method according to claim 11 , wherein sending the information of capability of the first station to the access point comprises:
sending the information of capability of the first station by means of a probe request frame, an association request frame or an authentication request frame.
13. The method according to claim 11 , wherein
sending the information of capability of the first station to the access point comprises at least one of:
sending, in response to the first station supporting multi-link sending and receiving, the information of capability comprising a first value to the access point;
sending, in response to the first station supporting multi-link sending or multi-link receiving, the information of capability comprising a second value to the access point; or
sending, in response to the first station supporting single-link sending or single-link receiving, the information of capability comprising a third value to the access point.
14. A communication device, comprising:
an antenna;
a memory; and
one or more processors, the one or more processors are collectively connected to the antenna and the memory respectively, and are collectively configured to control the antenna to receive and send by executing a computer-executable instruction stored in the memory, and are further collectively configured to implement the method according to claim 11 .
