  • Publication number: 20230114284
    Abstract: A method and device are disclosed for channel connection in a wireless communication system supporting multiple links. An operation method for the device comprises the steps of: performing a first back-off operation in a first link among multiple links; stopping the first back-off operation when the first link is determined to be in a busy state due to the first back-off operation; and using a new back-off counter value to perform a second back-off operation in a second link among the multiple links when the second link is in an idle state in a preset period prior to the point in time at which the first back-off operation is stopped.

  • Publication number: 20230040910
    Abstract: A method and an apparatus for STR in a wireless LAN that supports multi-links are disclosed. An operating method of a first communication node comprises the steps of: transmitting a first frame to a second communication node through a first link from among multi-links; receiving, from the second communication node, a response frame for the first frame through the first link; checking a channel occupancy time in a second link from among the multi-links on the basis of first information included in the response frame; and performing a sensing operation in a preset section after the end of the channel occupancy time in the second link.

  • Publication number: 20220287121
    Abstract: The present invention relates to an operating method of a first communication node in a communication system, comprising the steps of: negotiating with a second communication node with respect to a parameter for multi-link transmission; determining, on the basis of the parameter, a plurality of links for performing the multi-link transmission, and the transmission method by which the multi-link transmission is performed; and transmitting, in the plurality of links, a data frame to the second communication node by means of the transmission method. Therefore, the communication node can efficiently set and change links.
