1. A wireless communication terminal communicating wirelessly, the terminal comprising:
a wireless LAN (WLAN) transceiver configured to transmit and receive a WLAN signal; and
a wake-up radio (WUR) receiver configured to receive a WUR signal being transmitted based on on-off keying (OOK),
wherein the WUR receiver is configured to receive a wake-up part of a wake-up packet from a base wireless communication terminal and wake-up the WLAN transceiver, wherein the wake-up packet is distinguished into a legacy part that the WLAN transceiver is capable of demodulating and the wake-up part including the WUR signal,
wherein the legacy part comprises a legacy preamble part, which is a preamble included in a WLAN physical layer protocol data unit (PPDU) and only includes L-STF including short training signal, L-LTF including long training signal, and L-SIG including signaling information for a legacy wireless communication terminal, and an additional preamble part transmitted immediately after the legacy preamble part, wherein the L-SIG is set according to predetermined values,
wherein the additional preamble part only includes two Orthogonal Frequency Division Multiplexing (OFDM) symbols which are Binary Phase Shift keying (BPSK) modulated.
