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, to assist the part of or all of the stations in fast accessing a channel without waiting for a NAVSyncDelay time period.
Claims12
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 station that is to send an uplink service and that loses channel state information, and wherein the second station is comprised in the STA MLD;
- sending, by a second access point in the AP MLD to the second station, a downlink message frame on a second link corresponding to the second station, wherein the downlink message frame is configured to be used to assist the second station in sending the uplink service, and wherein the STA MLD does not support simultaneous transmitting and receiving;
- 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 instructions that are executable by the at least one processor, wherein the program includes 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 station that is to send an uplink service and that loses channel state information, and wherein the second station is comprised in the STA MLD;
- send, by the second access point to the second station, a downlink message frame on a second link corresponding to the second station, wherein the downlink message frame is configured to be used to assist the second station in sending the uplink service, and wherein the STA MLD does not support simultaneous transmitting and receiving;
- 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) to:
- receive, 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 station that is to send an uplink service and that loses channel state information, wherein the second station is in the STA MLD;
- send, to the second station, a downlink message frame on a second link corresponding to the second station, wherein the downlink message frame is configured to be used to assist the second station in sending the uplink service, and wherein the STA MLD does not support simultaneous transmitting and receiving;
- and
- receive the uplink service on the second link.
