    Abstract: A video signal processing method comprises the steps of: configuring a template including neighboring blocks of a current block; down-sampling luminance component samples of the neighboring blocks on the basis of a color format of a current picture including the current block; deriving a first linear model and a second linear model on the basis of the down-sampled luminance component samples; and on the basis of any one linear model from among the first linear model and the second linear model, predicting a chrominance component sample at a location corresponding to a location of a first sample from among the luminance component samples of the current block, wherein the any one linear model is determined by comparing a value of the first sample with a threshold value.

    Abstract: The present invention relates to a wireless communication method and a wireless communication terminal using a determination of basic service set identification information of a received frame, and more particularly, to a wireless communication method and a wireless communication terminal for performing an operation according to a determination result whether the received frame is an intra-BSS frame or an inter-BSS frame.
    To this end, provided are a wireless communication terminal including a processor and a communication unit, wherein the processor receives a wireless frame through the communication unit, when the received frame is a VHT PPDU, extracts partial association ID (AID) information and group ID information from a preamble of the VHT PPDU, when the extracted group ID information is equal to a predetermined value, checks whether at least some information of the extracted partial AID matches a partial basic service set (BSS) color announced to the terminal, and determines whether the received frame is an intra-BSS frame or an inter-BSS frame according to whether at least some information of the partial AID matches the partial BSS color and a wireless communication method using the same.

    Abstract: A method by which a terminal is to transmit a signal in a wireless communication system is disclosed. The terminal determines a specific resource set from among resource sets formed of one or more candidate resources allocated for the transmission of a physical sidelink shared channel (PSSCH), wherein: some or all of the one or more candidate resources constituting the resource sets overlap with a first resource for transmitting a first legacy signal of the terminal; and, if a first priority of the PSSCH is higher than a second priority of the legacy signal, the specific resource set can be determined by excluding, from the one or more candidate resources, at least one first candidate resource overlapping with the first resource. Afterward, the terminal can transmit the PSSCH on the specific resource set.

    Abstract: The present invention relates to a wireless communication system and, more particularly, to a method and a wireless device therefor, the method comprising the steps of: transmitting SL groupcast transmission to a plurality of terminals; identifying reception response results of the plurality of terminals for the SL groupcast transmission by monitoring a feedback signal in a PSFCH opportunity corresponding to the SL groupcast transmission; and configuring a CWS used for a channel access of SL transmission after the SL groupcast transmission, on the basis of the reception response results of the plurality of terminals, wherein, if the reception response results of the plurality of terminals include even one NACK, then the CWS is configured to have a greater value than a previous CWS, and if the reception response results of the plurality of terminals are all considered ACK, the CWS is reset to a CWS minimum value.
