A method for receiving downlink transmission by a terminal comprises the steps of: performing uplink transmission, which is related to channel occupancy shared between a base station and the terminal, to the base station; and receiving, from the base station, downlink transmission performed after a gap from a time point at which the base station has received the uplink transmission, wherein the downlink transmission is performed on the basis of channel access performed by the base station, the channel access is performed on the basis of the gap, and information included in the downlink transmission and a resource through which the downlink transmission is performed are determined on the basis of whether the base station has configured, for the terminal, a threshold value of energy detection for the channel occupancy.

A video signal decoding device comprises a processor which: decodes a general constraint information (GCI) syntax included in a bitstream of a video signal; and decodes the bitstream on the basis of the result of decoding the GCI syntax, wherein the GCI syntax includes a GCI syntax element for configuring the value of an SPS syntax element indicating whether it is possible to use a palette mode included in a sequence parameter set (SPS) raw byte sequence payload (RBSP) syntax.

Disclosed is a base station in a wireless communication system. Each base station in wireless communication comprises: a communication module; and a processor. The processor generates a hybrid automatic repeat request (HARQ)-ACK codebook comprising one or more bits and indicating whether or not reception of a channel or signal is successful, and transmits the HARQ-ACK codebook to the base station.
