Communication method and communication apparatus under multiple links

1 . A communication method under multiple links, performed by a station supporting multi-link communication, the communication method comprising:

determining a first message frame, wherein the first message frame comprises an information identification bit, and the information identification bit identifies that a first link among the multiple links is used for communication between a station in a power-saving state and an access point supporting multi-link communication;

transmitting the first message frame;

obtaining at least one of a transmission period or a time slot of a beacon frame under at least one link of the access point supporting multi-link communication; and

determining the first link based on at least one of the transmission period or the time slot.

2 . The communication method according to claim 1 , wherein determining the first link comprises:

determining the first link based on a listening interval or an idle period of the station.

3 . The communication method according to claim 2 , wherein determining the first link comprises:

determining a link with minimum time among the multiple links as the first link,

wherein the minimum time represents one of following time:

minimum time between the listening interval and the transmission period;

minimum time between the listening interval and the time slot;

minimum time between the idle period and the transmission period; or

minimum time between the idle period and the time slot.

4 . The communication method according to claim 1 , wherein the first link is used to cause a corresponding station to wake up according to the listening interval to perform communication, or the first link is used to transmit a message frame identifying that the station is within a coverage range of the access point.

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

receiving a second message frame, wherein the second message frame comprises identification information of a second link which is recommended by the access point and is different from the first link;

updating the first link as the second link.

6 . A communication method under multiple links, performed by an access point supporting multi-link communication, the communication method comprising:

receiving a first message frame, wherein the first message frame comprises an information identification bit, and the information identification bit identifies that a first link among the multiple links is used for communication between a station in a power-saving state and the access point supporting multi-link communication;

performing a communication operation based on the first message frame; and

transmitting information comprising at least one of a transmission period or a time slot of a beacon frame under at least one link of the access point,

wherein the first link is determined by the station based on at least one of the transmission period or the time slot.

7 . The communication method according to claim 6 , wherein the first link is determined by the station based on a listening interval or an idle period of the station.

8 . The communication method according to claim 7 , wherein the first link is a link with minimum time among the multiple links,

wherein the minimum time represents one of following time:

minimum time between the listening interval and the transmission period;

minimum time between the listening interval and the time slot;

minimum time between the idle period and the transmission period; or

minimum time between the idle period and the time slot.

9 . The communication method according to claim 6 , wherein the first link is used to cause a corresponding station to wake up according to the listening interval to perform communication, or the first link is used to transmit a message frame identifying that the station is within a coverage area of the access point supporting multi-link communication.

10 . The communication method according to claim 6 , further comprising:

recommending a second link different from the first link as an update of the first link based on the information identification bit and load information of the access point.

11 . An electronic device comprising a memory, a processor, and a computer program stored on the memory and executable by the processor, wherein the processor performs following acts when executing the computer program:

determining a first message frame, wherein the first message frame comprises an information identification bit, and the information identification bit identifies that a first link among multiple links is used for communication between a station in a power-saving state and an access point supporting multi-link communication;

transmitting the first message frame;

obtaining at least one of a transmission period or a time slot of a beacon frame under at least one link of the access point supporting multi-link communication; and

determining the first link based on at least one of the transmission period or the time slot.

12 . The electronic device according to claim 11 , wherein determining the first link comprises:

determining the first link based on a listening interval or an idle period of the station.

13 . The electronic device according to claim 12 , wherein determining the first link comprises:

determining a link with minimum time among the multiple links as the first link,

wherein the minimum time represents one of following time:

minimum time between the listening interval and the transmission period;

minimum time between the listening interval and the time slot;

minimum time between the idle period and the transmission period; or

minimum time between the idle period and the time slot.

14 . The electronic device according to claim 11 , wherein the first link is used to cause corresponding station to wake up according to the listening interval to perform communication, or the first link is used to transmit a message frame identifying that the station is within a coverage range of the access point.

15 . The electronic device according to claim 11 , wherein the processor further performs following acts when executing the computer program:

receiving a second message frame, wherein the second message frame comprises identification information of a second link which is recommended by the access point and is different from the first link;

updating the first link as the second link.

16 . An electronic device comprising a memory, a processor, and a computer program stored on the memory and executable by the processor, wherein the processor performs the method of claim 6 when executing the computer program.

17 . A non-transitory computer-readable storage medium, wherein a computer program is stored on the non-transitory computer-readable storage medium, and the computer program, when executed by a processor, implements the method according to claim 1 .

18 . A non-transitory computer-readable storage medium, wherein a computer program is stored on the non-transitory computer-readable storage medium, and the computer program, when executed by a processor, implements the method according to claim 6 .
