Method for performing communication in wireless LAN system, and wireless terminal using same
A method for communication performed by a first wireless terminal in a WLAN system according to an embodiment includes: generating a wake-up packet modulated by an on-off keying (OOK) scheme, the wake-up packet including a frame check sequence (FCS) field having a fixed length regardless of a length of the wake-up packet, and the fixed length being two bytes; and transmitting the wake-up packet.
1. A method for communication performed by a first wireless terminal in a wireless local area network (WLAN) system, the method comprising:
generating a wake-up packet modulated by an on-off keying (OOK) scheme, the wake-up packet comprising a frame check sequence (FCS) field having a fixed length regardless of a presence of a frame body in the wake-up packet, and the fixed length being two bytes; and
transmitting the wake-up packet to a plurality of second wireless terminals,
wherein, when the wake-up packet comprises broadcast identification information or group identification information for the plurality of second wireless terminals, the wake-up packet has a constant length, and
wherein, when the wake-up packet comprises a plurality of pieces of unicast identification information for the plurality of second wireless terminals, the wake-up packet has a variable length which is determined based on a number of the plurality of second wireless terminals.
2. A first wireless terminal for performing a method for communication in a wireless local area network (WLAN) system, the first wireless terminal comprising:
a transceiver to transmit and receive a radio signal; and
a processor connected to the transceiver,
wherein the processor is configured to:
generate a wake-up packet modulated by an on-off keying (OOK) scheme, the wake-up packet comprising a frame check sequence (FCS) field having a fixed length regardless of a presence of a frame body in the wake-up packet, and the fixed length being two bytes; and
transmit the wake-up packet to a plurality of second wireless terminals,
wherein, when the wake-up packet comprises broadcast identification information or group identification information for the plurality of second wireless terminals, the wake-up packet has a constant length, and
wherein, when the wake-up packet comprises a plurality of pieces of unicast identification information for the plurality of second wireless terminals, the wake-up packet has a variable length which is determined based on a number of the plurality of second wireless terminals.
