Abstract: A method for performing an uplink transmission to a base station by a user equipment through an unlicensed cell in a wireless communication system is provided. The method includes: receiving an uplink grant that schedules the uplink transmission in at least one subframe from the base station; and performing the uplink transmission in the at least one subframe using at least one of a first type channel access or a second type channel access. The uplink transmission is performed using the second type channel access when all of the at least one subframe is included in a predetermined interval determined based on a downlink transmission through the unlicensed cell from the base station.

Abstract: 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.

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.
