Communication method based on nonsimultaneous transmit and receive multi-link device, and apparatus
A communication method, includes: a first station in a multi-link station device obtain a channel on a first link through contention, and obtain a transmit opportunity (TXOP) on the first link; and the first station ends the TXOP before target sending time of a beacon frame of a second station, wherein the first station and the second station are stations of the multi-link station device, and when the first station performs sending or receiving, the second station is not capable of performing receiving or sending.
1 . A method, comprising:
obtaining, by a first station in a multi-link station device, a channel on a first link through contention;
obtaining, by the first station, a transmit opportunity (TXOP) on the first link;
determining, by the first station, that a second station needs to receive a beacon frame at a target sending time on a second link, wherein the beacon frame is a groupcast or broadcast frame; and
ending, by the first station, the TXOP before the target sending time of the beacon frame of the second station, wherein the second station is in the multi-link station device, and wherein, when the first station performs sending or receiving, the second station is not capable of performing receiving or sending, respectively.
2 . The method according to claim 1 , wherein the first link is between the first station and a first access point, and wherein the second link is between the second station and a second access point.
3 . The method according to claim 2 , wherein the first access point and the second access point belong to a same multi-link access point device.
4 . The method according to claim 1 , wherein the beacon frame indicates whether there is to-be-received broadcast or groupcast traffic.
5 . The method according to claim 4 , wherein the beacon frame further indicates a station having the to-be-received broadcast or groupcast traffic.
6 . The method according to claim 1 , the ending the TXOP comprising:
relinquishing, by the first station, the TXOP before the target sending time of the beacon frame.
7 . A first station, comprising:
at least one processor; and
a memory storing instructions for execution by the at least one processor, wherein, when executed, the instructions cause the first station to perform operations comprising:
obtaining a channel on a first link through contention;
obtaining a transmit opportunity (TXOP) on the first link;
determining that a second station needs to receive a beacon frame at a target sending time on a second link, wherein the beacon frame is a groupcast or broadcast frame; and
ending the TXOP before the target sending time of the beacon frame of the second station, wherein the first station and the second station are in a multi-link station device, and wherein, when the first station performs sending or receiving, the second station is not capable of performing receiving or sending, respectively.
8 . The first station according to claim 7 , wherein the first link is between the first station and a first access point, and wherein the second link is between the second station and a second access point.
9 . The first station according to claim 8 , wherein the first access point and the second access point belong to a same multi-link access point device.
10 . The first station according to claim 7 , wherein the beacon frame indicates whether there is to-be-received broadcast or groupcast traffic.
11 . The first station according to claim 10 , wherein the beacon frame further indicates a station having the to-be-received broadcast or groupcast traffic.
12 . A chip system for a first station, comprising:
a processing circuit; and
an input/output interface, wherein the processing circuit is configured to perform:
obtaining a channel on a first link through contention;
obtaining a transmit opportunity (TXOP) on the first link;
determining that a second station needs to receive a beacon frame at a target sending time on a second link, wherein the beacon frame is a groupcast or broadcast frame; and
ending the TXOP before the target sending time of the beacon frame of the second station, wherein the first station and the second station are in a multi-link station device, and wherein, when the first station performs sending or receiving, the second station is not capable of performing receiving or sending, respectively.
13 . The chip system according to claim 12 , wherein the first link is between the first station and a first access point, and wherein the second link is between the second station and a second access point.
14 . The chip system according to claim 13 , wherein the first access point and the second access point belong to a same multi-link access point device.
15 . The chip system according to claim 12 , wherein the beacon frame indicates whether there is to-be-received broadcast or groupcast traffic, and wherein the beacon frame further indicates a station having the to-be-received broadcast or groupcast traffic.
