Abstract: A method and a device for V2X communication channel estimation are disclosed. The V2X communication channel estimation according to an embodiment of the present disclosure may include calculating a first channel estimation value in a time-axis forward direction from a first midamble and a second channel estimation value in a time-axis backward direction from a second midamble located after the first midamble, based on a data pilot aided (DPA) channel estimation algorithm that uses a channel estimation value of a previous OFDM symbol to iteratively update a channel estimation value, and estimating, based on the first channel estimation value and the second channel estimation value, a final channel value of a specific OFDM symbol located between the first midamble and the second midamble.

Abstract: 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.
