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: 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.
