A method and device for updating parameters in a communication system supporting multi-link are disclosed. An operation method for a first device comprises: transmitting a first frame to a second device through a first link in a multi-link, the first frame including updated parameters used for a communication operation in the first link; transmitting a second frame to the second device through a second link in the multi-link, the second frame including information indicating that the updated parameters are present; and transmitting a third frame including the updated parameters to the second device through one link in the multi-link.

Method and device for updating parameters in communication system supporting multi-link

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.

Method and apparatus for STR in wireless LAN that supports multi-links

A multiplex transmission method and apparatus in a multi-link wireless LAN are disclosed. An operating method of a first device comprises the steps of: setting a first link linked with a second device and a first service; setting a second link linked with the second device and a second service; and performing communication with the second device by using the first link and/or the second link. Therefore, the performance of a communication system can be improved.

Multiplex transmission method and apparatus in multi-link wireless LAN

Disclosed is a method for transmitting/receiving information using WUR. A communication node comprises: a processor; a memory containing one or more instructions executed by the processor; a first transceiver operating on the basis of the one or more instructions; and a second transceiver operating on the basis of the one or more instructions.

Method for transmitting/receiving information using WUR

An operating method of a first communication node in a wireless communication network may include steps of: performing a monitoring operation on a first channel and a second channel; when states of the first channel and the second channel are idle states during a first section as a result of the monitoring operation, performing a random back-off operation in the first channel and the second channel; and when the state of the first channel and the state of the second channel are the idle states as a result of the random back-off operation, transmitting a first frame from the first channel and the second channel.
