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.
