Abstract

A link control method includes that: a first Non-AP MLD transmits a multi-link reconfiguration request frame to an AP MLD through a first Non-AP STA affiliated with the first Non-AP MLD; and receives a first status code transmitted by the AP MLD when the AP MLD receives the multi-link reconfiguration request frame from the first Non-AP STA affiliated with the first Non-AP MLD through a first AP affiliated with the AP MLD and a first address of at least one second Non-AP STA among Non-AP STAs affiliated with the first Non-AP MLD satisfies a first condition and/or a second condition. The first condition is related to at least one third Non-AP STA among Non-AP STAs affiliated with a second Non-AP MLD associated with the AP MLD. The second condition is related to fourth Non-AP STA(s) associated with a second AP affiliated with the AP MLD.

First claim

1 . A link control method, comprising:
transmitting, by a first Non-Access Point Multi-Link Device (Non-AP MLD), a multi-link reconfiguration request frame to an Access Point Multi-Link Device (AP MLD) through a first Non-Access Point Station (Non-AP STA) affiliated with the first Non-AP MLD; and receiving, by the first Non-AP MLD, a first status code transmitted by the AP MLD, the first status code being transmitted when the AP MLD receives the multi-link reconfiguration request frame transmitted by the first Non-AP STA affiliated with the first Non-AP MLD through a first Access Point (AP) affiliated with the AP MLD, and a first address of at least one second Non-AP STA among Non-AP STAs affiliated with the first Non-AP MLD satisfies a first condition and/or a second condition, wherein the multi-link reconfiguration request frame is used for requesting a multi-link reconfiguration, the first condition is related to at least one third Non-AP STA among Non-AP STAs affiliated with a second Non-AP MLD which is associated with the AP MLD, and the second condition is related to fourth Non-AP STA(s) which are associated with a second AP affiliated with the AP MLD.

2 . The method of claim 1 , wherein the first condition comprises: the first address of the at least one second Non-AP STA is the same as a second address of the at least one third Non-AP STA among the Non-AP STAs affiliated with the second Non-AP MLD.

3 . The method of claim 2 , wherein the first condition further comprises: the at least one second Non-AP STA operates on the same channel as the at least one third Non-AP STA.

4 . The method of claim 3 , wherein a channel on which the first AP operates is the same as or different from the channel on which the at least one second Non-AP STA operates.

5 . The method of claim 1 , wherein the second condition comprises: the first address of the at least one second Non-AP STA is the same as a third address of at least one fourth Non-AP STA among Non-AP STAs which are associated with the second AP.

6 . The method of claim 5 , wherein the second condition further comprises: the at least one second Non-AP STA operates on the same channel as the at least one fourth Non-AP STA.

7 . The method of claim 6 , wherein a channel for the second AP is the same as the channel on which the at least one second Non-AP STA operates.

8 . The method of claim 1 , wherein the multi-link reconfiguration request frame is used for requesting the multi-link reconfiguration when the multi-link reconfiguration request frame comprises a reconfiguration multi-link element,
wherein the reconfiguration multi-link element comprises the first address of the at least one second Non-AP STA affiliated with the first Non-AP MLD.

9 . The method of claim 8 , wherein the at least one second Non-AP STA affiliated with the first Non-AP MLD requests to add a link in a case where the first Non-AP MLD establishes a multi-link with the AP MLD.

10 . The method of claim 1 , wherein the first status code is used for indicating rejection of a multi-link reconfiguration request when the multi-link reconfiguration request frame is used for requesting the multi-link reconfiguration; and/or
the first status code is used for rejecting reconfiguration of conflicting link(s) in the multi-link reconfiguration request frame when the multi-link reconfiguration request frame is used for requesting the multi-link reconfiguration.

11 . A first Non-Access Point Multi-Link Device (Non-AP MLD), comprising:
a processor; and a memory for storing a computer program that, when executed by the processor, causes the first Non-AP MLD to: transmit a multi-link reconfiguration request frame to an Access Point Multi-Link Device (AP MLD) through a first Non-Access Point Station (Non-AP STA) affiliated with the first Non-AP MLD; and receive a first status code transmitted by the AP MLD, the first status code being transmitted when the AP MLD receives the multi-link reconfiguration request frame transmitted by the first Non-AP STA affiliated with the first Non-AP MLD through a first Access Point (AP) affiliated with the AP MLD, and a first address of at least one second Non-AP STA among Non-AP STAs affiliated with the first Non-AP MLD satisfies a first condition and/or a second condition, wherein the multi-link reconfiguration request frame is used for requesting a multi-link reconfiguration, the first condition is related to at least one third Non-AP STA among Non-AP STAs affiliated with a second Non-AP MLD which is associated with the AP MLD, and the second condition is related to fourth Non-AP STA(s) which are associated with a second AP affiliated with the AP MLD.

12 . The first Non-AP MLD of claim 11 , wherein the first condition comprises: the first address of the at least one second Non-AP STA is the same as a second address of the at least one third Non-AP STA among the Non-AP STAs affiliated with the second Non-AP MLD.

13 . The first Non-AP MLD of claim 12 , wherein the first condition further comprises: the at least one second Non-AP STA operates on the same channel as the at least one third Non-AP STA.

14 . The first Non-AP MLD of claim 13 , wherein a channel on which the first AP operates is the same as or different from the channel on which the at least one second Non-AP STA operates.

15 . The first Non-AP MLD of claim 11 , wherein the second condition comprises: the first address of the at least one second Non-AP STA is the same as a third address of at least one fourth Non-AP STA among Non-AP STAs which are associated with the second AP.

16 . The first Non-AP MLD of claim 15 , wherein the second condition further comprises: the at least one second Non-AP STA operates on the same channel as the at least one fourth Non-AP STA.

17 . The first Non-AP MLD of claim 16 , wherein a channel for the second AP is the same as the channel on which the at least one second Non-AP STA operates.

18 . The first Non-AP MLD of claim 11 , wherein the multi-link reconfiguration request frame is used for requesting the multi-link reconfiguration when the multi-link reconfiguration request frame comprises a reconfiguration multi-link element,
wherein the reconfiguration multi-link element comprises the first address of the at least one second Non-AP STA affiliated with the first Non-AP MLD.

19 . The first Non-AP MLD of claim 18 , wherein the at least one second Non-AP STA affiliated with the first Non-AP MLD requests to add a link in a case where the first Non-AP MLD establishes a multi-link with the AP MLD.

20 . The first Non-AP MLD of claim 11 , wherein the first status code is used for indicating rejection of a multi-link reconfiguration request when the multi-link reconfiguration request frame is used for requesting the multi-link reconfiguration; and/or
the first status code is used for rejecting reconfiguration of colliding link(s) in the first frame when the multi-link reconfiguration request frame is used for requesting the multi-link reconfiguration.
