Method for coordinated multi-access point AP transmission and related apparatus
Example methods for multi-access point (AP) coordination and apparatus are described. One example method includes generating a first radio frame by a first AP. The first radio frame includes indication information used to indicate transmission duration of a second radio frame sent by a second AP. The first AP sends the first radio frame to the second AP. In a sending period of the second radio frame, the first AP sends a third radio frame to a first station (STA) associated with the first AP.
1. An apparatus for coordinated multi-access point (AP) transmission, wherein the apparatus is applied to a first AP side, and wherein the apparatus comprises:
at least one processor;
a non-transitory computer-readable storage medium coupled to the processor and storing programming instructions for execution by the at least one processor, the programming instructions instruct the at least one processor to generate a first radio frame, wherein the first radio frame comprises indication information used to indicate 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
a transceiver, configured to:
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.
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 third radio frame is the same as the sending time of the second radio frame.
4. The apparatus according to claim 1 , wherein a sending time of the third radio frame is before the sending time of the second 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 transmission duration of the third radio frame is the same as the transmission duration of the second 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. An apparatus for coordinated multi-access point (AP) transmission, wherein the apparatus is applied to a second AP side, and wherein the apparatus comprises:
a transceiver, configured to:
receive a first radio frame sent by a first AP, wherein the first radio frame comprises indication information used to indicate transmission duration of a second radio frame, 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.
9. The apparatus according to claim 8 , wherein the indication information comprises a sending time and an end time of the second radio frame.
10. The apparatus according to claim 8 , wherein a sending time of the second radio frame is the same as a sending time of the third radio frame.
11. The apparatus according to claim 8 , wherein a sending time of the second radio frame is before a sending time of the third radio frame.
12. The apparatus according to claim 8 , wherein the indication information comprises identifier information of the second AP.
13. The apparatus according to claim 8 , wherein the transmission duration of the second radio frame is the same as transmission duration of the third radio frame.
14. The apparatus 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.
15. A method for coordinated multi-access point (AP) transmission, comprising:
generating, by a first AP, a first radio frame, wherein the first radio frame comprises indication information used to indicate 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;
sending, by the first AP, the first radio frame to the second AP; and
in a sending period of the second radio frame, sending, by the first AP, a third radio frame to a first station (STA) associated with the first AP.
16. The method according to claim 15 , wherein the indication information comprises a sending time and an end time of the second radio frame.
17. The method according to claim 15 , wherein a sending time of the third radio frame is the same as the sending time of the second radio frame.
18. The method according to claim 15 , wherein a sending time of the third radio frame is before the sending time of the second radio frame.
19. The method according to claim 15 , wherein the indication information comprises identifier information of the second AP.
