Abstract: A station in a wireless communication system is disclosed. The station includes: a transceiver; and a processor for controlling the transceiver. The processor receives a trigger frame for triggering uplink transmission from an access point (AP), and the trigger frame allocates, to the station, a part of a transmission opportunity (TXOP) acquired by the AP, as a shared TXOP, transmits a CTS frame as a response to the trigger frame, and switches a first enhanced distributed channel access (EDCA) parameter set used for channel access to a second EDCA parameter set based on transmission for the AP within the shared TXOP.

Abstract: Provided is a method for transmitting, by a terminal, a physical uplink shared channel (PUSCH) to a base station in a wireless communication system. The method comprises: a step for receiving, from a base station, an radio resource control (RRC) signal including configuration information on a semi-static uplink symbol, a flexible symbol, and a downlink symbol; a step for receiving a physical downlink control channel (PDCCH) for scheduling a PUSCH transmission including at least one PUSCH repetition; a step for determining whether at least one of the required number of symbols for transmitting the PUSCH repetition cannot transmit the PUSCH repetition; and a step for transmitting the PUSCH repetition to the base station on the basis of the determination on whether the PUSCH repetition cannot be transmitted. When the PUSCH repetition cannot be transmitted, at least one of the symbols is a symbol designated as a semi-static downlink symbol by the configuration information.

Abstract: Disclosed is a method by which a terminal transmits a physical uplink shared channel (PUSCH) to a base station in a wireless communication system. The terminal can receive, from the base station, configuration information for allocating a resource for transmitting a transport block (TB) through the PUSCH, and map the TB to a plurality of slots constituting the resource on the basis of the configuration information. Thereafter, the terminal can transmit the TB on the plurality of slots through the PUSCH.

Abstract: A video signal processing method comprises the steps of: receiving information for prediction of a current block; determining whether or not a merge mode is applied to the current block on the basis of the information for prediction; when a merge mode is applied to the current block, obtaining a first syntax element indicating whether or not a combined prediction is applied to the current block, wherein the combined prediction indicates a prediction mode that combines inter-prediction and intra-prediction; generating an inter-prediction block and an intra-prediction block of the current block when the first syntax element indicates that the combined prediction is applied to the current block; and generating a combined prediction block of the current block by weighted-summing the inter-prediction block and the intra-prediction block.
