摘要： The present invention relates to a method for operating a first communication node in a wireless local area network (WLAN) supporting a multi-link operation, comprising the steps of: setting a first transmit window size of a first link for transmitting a plurality of frames to a second communication node; transmitting the plurality of frames through the first link; when the state of a channel detected through channel sensing in the second link is an idle state, setting a transmit opportunity (TXOP) in the channel; and when the transmit opportunity is set, performing an agreement with the second communication node on the size of a second transmit window for transmitting the plurality of frames. Therefore, it is possible to improve the performance of a communication system.

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.

摘要： A method and apparatus for NSTR communication in a communication system supporting multiple links are disclosed. A method for a first device comprises the steps of if a first backoff operation has succeeded on a first link belonging to a first pair of NSTR links on which an STR operation of a second device is not supported, transmitting a first data frame to the second device on the first link; performing a second backoff operation for transmission of a second data frame on a second link belonging to the first pair of NSTR links; if the second backoff operation has succeeded on the second link, identifying whether or not a transmission operation of the second device is performed on the first link belonging to the pair of NSTR links; and if the transmission operation is performed on the first link, transmitting the second data frame to the second device on the second link after completion of the transmission operation.

摘要： A method and a device for shard communication in a wireless LAN are disclosed. A method of a first STA comprises the steps of: receiving a first frame for allocation of a shared communication period from an AP; identifying the shared communication period on the basis of one or more fields included in the first frame; and performing shared communication with a second STA in the shared communication period, wherein the shared communication period is configured within a TXOP configured between the AP and a third STA.

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.
