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.

Abstract: Disclosed are a method and device for direct communication in a wireless LAN. An operation method of a first device comprises the steps of: transmitting a first frame, which is for setting up a direct communication link, to a second device over one or more links among multiple links; receiving a second frame, which is a response to the first frame, from the second device over the one or more links; and directly communicating with one or more peer devices over the direct communication link when the second frame is received.

Abstract: Disclosed is a method for operating a communication node supporting a low power mode in a wireless LAN. A method for operating a station, which includes a PCR and a WURx, comprises the steps of: allowing the WURx, which operates in a wake-up state, to receive a wake-up packet from an access point; transitioning an operating state of the PCR from a sleep state to the wake-up state when the wake-up packet is received; allowing the PCR, which operates in the wake-up state, to receive a data frame from an access point; and allowing the PCR to transmit, to the access point, a response to the data frame.
