Abstract

Embodiments of this application disclose a method for multi-access point AP coordination and a related apparatus. The method in the embodiments of this application includes: generating, by a first access point AP, a first radio frame, where the first radio frame includes indication information used to indicate transmission duration of a second radio frame sent by a second access point AP; sending, by the first access point AP, the first radio frame to the second access point AP; and in a sending period of the second radio frame, sending, by the first access point AP, a third radio frame to a first station STA associated with the first access point AP.

Claims (29)

1 . An apparatus, comprising:

at least one processor; and

one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to:

receive a first radio frame sent by a first access point (AP), wherein the first radio frame comprises indication information indicating a transmission duration of a second radio frame sent by a second AP, and wherein the first radio frame carries transmit power information of the second AP; and

send, in a sending period of sending a third radio frame by the first AP to a first station (STA) associated with the first AP, the second radio frame to a second STA associated with the second AP.

2 . The apparatus according to claim 1 , wherein the indication information comprises a sending time and an end time of the second radio frame.

3 . The apparatus according to claim 1 , wherein a sending time of the second radio frame is the same as a sending time of the third radio frame.

4 . The apparatus according to claim 1 , wherein a sending time of the second radio frame is earlier than a sending time of the third radio frame.

5 . The apparatus according to claim 1 , wherein the indication information comprises identifier information of the second AP.

6 . The apparatus according to claim 1 , wherein the transmission duration of the second radio frame is the same as a transmission duration of the third radio frame.

7 . The apparatus according to claim 1 , wherein the first radio frame further carries one or more of the following: information about a maximum tolerable interference threshold for the first AP, or transmit power information of the first AP.

8 . A non-transitory computer-readable medium, applied in a first access point (AP), the non-transitory computer-readable medium storing programming instructions for execution by one or more processors to:

generate a first radio frame, wherein the first radio frame comprises indication information indicating a transmission duration of a second radio frame sent by a second AP, and wherein the first radio frame carries transmit power information of the second AP;

send the first radio frame to the second AP; and

in a sending period of the second radio frame, send a third radio frame to a first station (STA) associated with the first AP.

9 . The non-transitory computer-readable medium according to claim 8 , wherein the indication information comprises a sending time and an end time of the second radio frame.

10 . The non-transitory computer-readable medium according to claim 8 , wherein a sending time of the third radio frame is the same as a sending time of the second radio frame.

11 . The non-transitory computer-readable medium according to claim 8 , wherein a sending time of the third radio frame is earlier than a sending time of the second radio frame.

12 . The non-transitory computer-readable medium according to claim 8 , wherein the indication information comprises identifier information of the second AP.

13 . The non-transitory computer-readable medium according to claim 8 , wherein the first radio frame further carries one or more of the following: information about a maximum tolerable interference threshold for the first AP, or transmit power information of the first AP.

14 . A non-transitory computer-readable medium, applied in a second access point (AP), the non-transitory computer-readable medium storing programming instructions for execution by one or more processors to:

receive a first radio frame sent by a first AP, wherein the first radio frame comprises indication information indicating a transmission duration of a second radio frame sent by the second AP, and wherein the first radio frame carries transmit power information of the second AP; and

in a sending period of sending a third radio frame by the first AP to a first station (STA) associated with the first AP, send the second radio frame to a second STA associated with the second AP.

15 . The non-transitory computer-readable medium according to claim 14 , wherein the indication information comprises a sending time and an end time of the second radio frame.

16 . The non-transitory computer-readable medium according to claim 14 , wherein a sending time of the second radio frame is the same as a sending time of the third radio frame.

17 . The non-transitory computer-readable medium according to claim 14 , wherein a sending time of the second radio frame is earlier than a sending time of the third radio frame.

18 . The non-transitory computer-readable medium according to claim 14 , wherein the indication information comprises identifier information of the second AP.

19 . The non-transitory computer-readable medium according to claim 14 , wherein the transmission duration of the second radio frame is the same as a transmission duration of the third radio frame.

20 . The non-transitory computer-readable medium according to claim 14 , wherein the first radio frame further carries one or more of the following: information about a maximum tolerable interference threshold for the first AP, or transmit power information of the first AP.
