Abstract

A management method employed by an access point (AP) multi-link device (MLD) includes: during association between the AP MLD and a non-AP MLD, obtaining capability indications signaled from the non-AP MLD, wherein the capability indications comprise at least a link addition capability indication of the non-AP MLD; and performing resource allocation for links between the AP MLD and the non-AP MLD according to at least a portion of the capability indications.

Claims (21)

1 . A management method employed by an access point (AP) multi-link device (MLD), comprising:

during association between the AP MLD and a non-AP MLD, obtaining capability indications signaled from the non-AP MLD, wherein the capability indications comprise at least a link addition capability indication of the non-AP MLD, wherein the link addition capability indication indicates that the non-AP MLD is capable of adding at least one new link between the AP MLD and the non-AP MLD after the association, and the at least one new link is not set up during the association; and

performing resource allocation for links between the AP MLD and the non-AP MLD according to at least a portion of the capability indications.

2 . The management method of claim 1 , wherein the AP MLD is capable of providing services on N links, M links are set up by the non-AP MLD during the association between the AP MLD and the non-AP MLD, and performing the resource allocation for links between the AP MLD and the non-AP MLD according to said at least a portion of the capability indications comprises:

in response to M being smaller than N and the link addition capability indication indicating that the non-AP MLD is incapable of adding a link, allocating resources for only the M links.

3 . The management method of claim 1 , wherein the AP MLD is capable of providing services on N links, M links are set up by the non-AP MLD during the association between the AP MLD and the non-AP MLD, and performing the resource allocation for links between the AP MLD and the non-AP MLD according to said at least a portion of the capability indications comprises:

in response to M being equal to N, allocating resources for the M links regardless of the link addition capability indication.

4 . The management method of claim 1 , wherein the AP MLD is capable of providing services on N links, M links are set up by the non-AP MLD during the association between the AP MLD and the non-AP MLD, and performing the resource allocation for links between the AP MLD and the non-AP MLD according to said at least a portion of the capability indications comprises:

in response to M being smaller than N and the link addition capability indication indicating that the non-AP MLD is capable of adding a link, allocating resources for K links, where K is larger than M, and is not larger than N.

5 . The management method of claim 4 , wherein K is equal to N.

6 . The management method of claim 4 , wherein the capability indications further comprise a maximum number of links that the non-AP MLD supports, and K is equal to the maximum number of links that the non-AP MLD supports.

7 . A management method employed by an access point (AP) multi-link device (MLD), comprising:

during association between the AP MLD and a non-AP MLD, obtaining capability indications signaled from the non-AP MLD, and activating only M links of the AP MLD, wherein the AP MLD is capable of providing services on N links, and N is larger than M; and

in response to the AP MLD adding a new link to the M links after the association, instructing or recommending the non-AP MLD to utilize the new link according to a subset of the capability indications, wherein the new link is not activated during the association.

8 . The management method of claim 7 , wherein the subset of the capability indications comprises a link addition capability indication of the non-AP MLD and a maximum number of links that the non-AP MLD supports, and instructing or recommending the non-AP MLD to utilize the new link according to the subset of the capability indications comprises:

in response to the link addition capability indication indicating that the non-AP MLD is capable of adding a link and the non-AP MLD not using maximum number of links that the non-AP MLD supports, instructing or recommending the non-AP MLD to add a link connection to the new link.

9 . The management method of claim 7 , wherein the subset of the capability indications comprises a link switch capability indication of the non-AP MLD, and instructing or recommending the non-AP MLD to utilize the new link according to the subset of the capability indications comprises:

in response to the link switch capability indication indicating that the non-AP MLD is capable of switching a first link to a second link, instructing or recommending the non-AP MLD to switch a current link to the new link, where the current link is the first link indicated by the link switch capability indication, and the new link is the second link indicated by the link switch capability indication.

10 . An access point (AP) multi-link device (MLD) comprising:

a network interface circuit, arranged to obtain capability indications signaled from the non-AP MLD during association between the AP MLD and a non-AP MLD, wherein the capability indications comprise at least a link addition capability indication of the non-AP MLD, wherein the link addition capability indication indicates that the non-AP MLD is capable of adding at least one new link between the AP MLD and the non-AP MLD after the association, and the at least one new link is not set up during the association; and

a control circuit, arranged to perform resource allocation for links between the AP MLD and the non-AP MLD according to at least a portion of the capability indications.
