摘要： Disclosed is a wireless communication terminal for performing communication wirelessly. The wireless communication terminal includes: a first wireless transceiver, which transmits/receives a signal through a first waveform; a second wireless receiver, which receives a signal through a second waveform different from the first waveform; and a processor. The processor receives, via the second wireless receiver, a first wake-up radio (WUR) frame from a base wireless communication terminal of a basic service set (BSS) to which the wireless communication terminal belongs, determines whether the wireless communication terminal is an intended recipient of the first WUR according to whether the BSS is one corresponding to a multiple BSS identifier (BSSID) set when an identifier field of the first WUR frame indicates a transmitter ID for identifying the base wireless communication terminal, and wakes up the first wireless transceiver based on the first WUR frame when the wireless communication terminal is the intended recipient of the first WUR frame.

摘要： Provided is a wireless communication terminal. The processor is configured to receive, from a base wireless communication terminal through the transceiver, a first frame including first information indicating a duration required for a pending frame exchange sequence and second information indicating a frequency band which is allocated for transmission of a second frame, wherein the pending frame exchange sequence is a transmission sequence between one or more wireless communication terminals, set a network allocation vector (NAV) according to the first information indicating the duration for the pending frame exchange sequence, and reset the NAV when the wireless communication terminal does not receive a PLCP Protocol Data Unit (PPDU) for a reference time from a time point at which the first frame is received.

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.
