Abstract
A STA in a STA MLD sends an information frame on a link corresponding to the station, and the information frame is used to indicate a STA in an awake state in the STA MLD. An AP MLD receives the information frame, and sends a downlink message frame on a one or more links corresponding to a part of or all of STAs in the awake state in the STA MLD.
Claims15
A multi-link communication method, comprising:
- receiving, by a first access point in an access point multi-link device (AP MLD) from a first station in a station multi-link device (STA MLD), an information frame on a first link corresponding to the first station, wherein the information frame indicates a second link corresponding to a second station in the STA MLD, wherein the second station losses channel state information on the second link and has uplink service to send on the second link;
- sending, by a second access point in the AP MLD to the second station, a downlink message frame on the second link, wherein the downlink message frame is configured to assist the second station in sending the uplink service;
- and
- receiving, by the second access point, the uplink service on the second link.
An access point multi-link device (AP MLD), comprising:
- at least one processor;
- and
- a memory storing a program that is executable by the at least one processor, wherein the program comprises instructions for a first access point and a second access point of the AP MLD, and executing the instructions causes the AP MLD to:
- receive, by the first access point from a first station in a station multi-link device (STA MLD), an information frame on a first link corresponding to the first station, wherein the information frame indicates a second link corresponding to a second station in the STA MLD, wherein the second station losses channel state information on the second link and has uplink service to send on the second link;
- send, by the second access point in the AP MLD to the second station, a downlink message frame on the second link, wherein the downlink message frame is configured to assist the second station in sending the uplink service;
- and
- receive, by the second access point, the uplink service on the second link.
A non-transitory computer-readable storage medium, storing a computer program, wherein the computer program comprises instructions which cause an access point multi-link device (AP MLD) comprising a first access point and a second access point to:
- receive, by the first access point from a first station in a station multi-link device (STA MLD), an information frame on a first link corresponding to the first station, wherein the information frame indicates a second link corresponding to a second station in the STA MLD, wherein the second station losses channel state information on the second link and has uplink service to send on the second link;
- send, by the second access point in the AP MLD to the second station, a downlink message frame on the second link, wherein the downlink message frame is configured to assist the second station in sending the uplink service;
- and
- receive, by the second access point, the uplink service on the second link.
