Abstract: A method for receiving a WUR frame by a STA in a WLAN according to one embodiment of the present invention may comprise the steps of: receiving a WUR frame comprising a frame control field, an address field, a TD control field, and a frame body; and acquiring BSSID-related information, SSID-related information, and PCR channel-related information from the WUR frame, according to a determination that the WUR frame is a WUR frame for broadcasting information used to find an AP, wherein: the BSSID-related information is obtained by abbreviating an entire BSSID of the AP, and a first part and a second part of the abbreviated BSSID are acquired from the address field and the TD control field, respectively; and the SSID-related information is obtained by abbreviating an entire SSID of the AP, and the abbreviated SSID is acquired from the frame body.

Abstract: A method and device for transmitting data in a wireless LAN system are provided. Particularly, a transmission device receives configuration information relating to a multi-band. The transmission device performs channel sensing with respect to the multi-band. The transmission device transmits data to a reception device via the multi-band on the basis of the result of the channel sensing. A first band and a second band are combined in the multi-band. The first band comprises a first primary channel, and the second band comprises a second primary channel. The result of the channel sensing is obtained on the basis of whether or not the first primary channel is idle until a first BC value becomes 0 and whether or not the second primary channel is idle until a second BC value becomes 0. The first BC value is selected within a first CW configured with respect to the first primary channel. The second BC value is selected within a second CW configured with respect to the second primary channel.

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.
