Abstract: A method for performing communication based on a power saving operation in a wireless LAN system according to an embodiment includes: receiving, by a first wireless terminal including a main radio module and a wake-up radio (WUR) module for receiving a wake-up packet modulated with on-off keying (OOK), the wake-up packet from a second wireless terminal based on the WUR module in a WUR mode in which the WUR module is controlled to alternate between a turn-on state and a turn-off state based on a power state of the main radio module, the wake-up packet including information related to an individually addressed frame for the first wireless terminal; and controlling, by the first wireless terminal, the main radio module such that the main radio module is in an awake state in a predetermined service period related to the main radio module when a predetermined time has elapsed after reception of the wake-up packet.

Abstract: A method in a wireless local area network (WLAN) system is performed by a first wireless terminal and includes: receiving a wake-up radio (WUR) mode request frame from a second wireless terminal; allocating first identification information for the second wireless terminal, wherein the first identification information is configured based on a value obtained by adding a first value related to a transmitter identifier (TXID) of the first wireless terminal and a second value related to an association identifier (AID) of the second wireless terminal; determining whether the first identification information coincides with pre-allocated one or more pieces of second identification information; reallocating a value randomly selected from among predetermined candidate values to the first identification information; and transmitting a WUR mode response frame including the re-allocated first identification information to the second wireless terminal.
