Abstract

A communication method and system in a WLAN, and an apparatus, are disclosed. An access point device sends a first frame to a non-access point device. The first frame includes one or more groups of access point parameters. At least one group of the access point parameters includes parameters of a plurality of access points belonging to one neighbor device. The neighbor device is an access point multi-link device. The non-access point device is associated with the access point device.

First claim

What is claimed is:

1 . A method in a wireless local area network, the method comprising:
receiving, by a non-access point device, a first frame from an access point device, wherein the first frame comprises one or more groups of access point parameters, at least one group of the one or more groups of access point parameters comprises parameters of a plurality of access points belonging to one neighbor device of the access point device, the one neighbor device is a access point multi-link device, and the non-access point device is associated with the access point device; and wherein the first frame comprises one or more neighbor report elements, and each of the neighbor report elements comprises one group of the access point parameters; and wherein for each group of access point parameters that comprises parameters of a plurality of access points, a parameter of one access point in the plurality of access points is in the neighbor report element, and a parameter of another access point in the plurality of access points is in a subelement of the neighbor report element.

2 . The method according to claim 1 , wherein the access point device is an access point multi-link device.

3 . The method according to claim 1 , wherein the non-access point device is a non-access point multi-link device.

4 . The method according to claim 1 , further comprising:
parsing, by the non-access point device, the first frame.

5 . The method according to claim 1 , wherein the first frame further comprises a first indication, and the first indication indicates a type of the first frame.

6 . The method according to claim 1 , further comprising:
sending, by the non-access point device, a second frame to the access point device, wherein the second frame requests to obtain a parameter of the one neighbor access point of the access point device.

7 . The method according to claim 6 , wherein the second frame further comprises a second indication, and the second indication indicates a type of the second frame.

8 . The method according to claim 6 , wherein the second frame is a basic service set transition management (BTM) query frame, the second frame further comprises a third indication, and the third indication indicates that a reason why the non-access point device requests to obtain the parameter of the neighbor access point of the access point device comprises: the access point device does not have a capability of receiving data and sending data on different links simultaneously.

9 . The method according to claim 1 , wherein the first frame is a neighbor report response frame.

10 . The method according to claim 1 , further comprising:
sending, by the non-access point device, a basic service set transition management (BTM) response frame to the access point device.

11 . The method according to claim 1 , wherein each parameter of the parameters of the plurality of access points comprises a basic service set identifier of the access point.

12 . The method according to claim 1 , wherein the first frame is a basic service set transition management (BTM) request frame.

13 . A non-access point device, comprising:
a processor; and a transceiver; wherein the processor is configured to invoke a computer program, and the computer program, when invoked by the processor, causes the non-access point device to:
receive a first frame from an access point device, wherein the first frame comprises one or more groups of access point parameters, at least one group of the one or more groups of access point parameters comprises parameters of a plurality of access points belonging to one neighbor device of the access point device, the one neighbor device is a access point multi-link device, and the non-access point device is associated with the access point device; and
wherein the first frame comprises one or more neighbor report elements, and each of the neighbor report elements comprises one group of the access point parameters; and wherein for each group of access point parameters that comprises parameters of a plurality of access points, a parameter of one access point in the plurality of access points is in the neighbor report element, and a parameter of another access point in the plurality of access points is in a subelement of the neighbor report element.

14 . The non-access point device according to claim 13 , wherein the access point device is an access point multi-link device.

15 . The non-access point device according to claim 13 , wherein the non-access point device is a non-access point multi-link device.

16 . The non-access point device according to claim 13 , wherein the computer program, when invoked by the processor, causes the non-access point device to:
parse the first frame.

17 . The non-access point device according to claim 13 , wherein the first frame further comprises a first indication, and the first indication indicates a type of the first frame.

18 . The non-access point device according to claim 13 , wherein the computer program, when invoked by the processor, causes the non-access point device to:
send a second frame to the access point device, wherein the second frame requests to obtain a parameter of a neighbor access point of the access point device.

19 . The non-access point device according to claim 18 , wherein the second frame further comprises a second indication, and the second indication indicates a type of the second frame.

20 . The non-access point device according to claim 18 , wherein the second frame is a basic service set transition management (BTM) query frame, the second frame further comprises a third indication, and the third indication indicates that a reason why the non-access point device requests to obtain the parameter of the neighbor access point of the access point device comprises: the access point device does not have a capability of receiving data and sending data on different links simultaneously.
