Title:
WIRELESS COMMUNICATION METHOD USING MULTI-LINK, AND WIRELESS COMMUNICATION TERMINAL USING SAME
Document Type and Number:
WIPO Patent Application WO/2022/164293
Kind Code:
A1
Abstract:
Disclosed is a multi-link device which includes a plurality of stations respectively operating in a plurality of links, but which, in an enhanced multi-link single radio (EMLSR) mode, does not perform transmission and reception in a second link of an EMLSR link while performing frame exchange in a first link of the EMLSR link, wherein the EMLSR link is a plurality of links to which the EMLSR mode is applied. The multi-link device comprises a transmission and reception unit, and a processor. When in the EMLSR mode, a first station, which is one of the plurality of stations included in the multi-link device, performs the frame exchange as a transmission opportunity (TXOP) holder in the first link, the processor ends the TXOP for the frame exchange before a point in time that arrives a pre-designated time earlier than the point in time at which the multi-link device is to receive a beacon frame. The pre-designated time is a delay time for the multi-link device to perform link switching.
