摘要： Disclosed are a method and apparatus for transmitting and receiving data in a communication system supporting multiple links. A method for operation of a first device comprises the steps of: transmitting, in a first link from among multiple links, a first RTS frame to a second device; receiving, from the second device in the first link, a first CTS frame that is a response to the first RTS frame; when the first CTS frame is received, transmitting, in the first link, a first data frame to the second device; and transmitting, in a second link during transmission of the first data frame, a second RTS frame to the second device.

摘要： 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.

摘要： 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.
