摘要： Disclosed are a traffic transmission method and device, the method being performed by a terminal in a wireless communication system. Specifically, a non-access point (AP) STA of the present invention can receive, from an AP, a trigger frame triggering the transmission of a physical layer protocol data unit (PPDU). The trigger frame includes information indicating at least one traffic identifier (TID) that is allowed to be transmitted in a target wake time (TWT) period. The TWT period may indicate a period in which the transmission of traffic for the at least one TID having a specific transmission condition is allowed, and the transmission of traffic not having the specific transmission condition is restricted. Thereafter, the non-AP STA transmits a PPDU, including the traffic corresponding to the at least one TID, to the AP within the TWT period.

摘要： 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.

摘要： 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.
