    Abstract: A method by which an access point (AP) transmits a frame in a wireless LAN, according to one embodiment of the present disclosure, comprises: determining a wake-up radio (WUR) identifier (WID) for identifying a station (STA) and a group identifier (GID) for identifying an STA group to which the STA belongs, in a WUR mode; transmitting the WID and the GID through a primary connectivity radio (PCR) so as to allocate, to the STA, the determined WID and GID; and transmitting, based on the GID or the WID, a WUR frame for waking up a plurality of STAs including the STA operating in the WUR mode, wherein the AP can determine the GID by using a part of an ID space which can be used in the WUR, and determine the WID by using the remaining space excluding the partial ID space used for the GID.

    Abstract: A method for receiving a frame in a wireless LAN system according to the present embodiment comprises the steps of: receiving transmission speed information according to a transmission type of a wakeup packet for a WUR module from a second wireless terminal by a first wireless terminal including a main radio module and the WUR module, wherein the transmission speed information is set on the basis of at least three transmission speeds for the wakeup packet, and the transmission speed information is received on the basis of the main radio module; and receiving the wakeup packet on the basis of the transmission speed information from the second wireless terminal by the first wireless terminal, wherein a header of the wakeup packet includes a transmission type indicator for the transmission type of the wakeup packet, the wakeup packet is modulated according to an on-off keying (OOK) scheme, and the wakeup packet is received on the basis of the WUR module.

    Abstract: A method in a wireless local area network (WLAN) includes receiving, from an access point (AP) by a station (STA), a beacon frame comprising a first field related to a transmission time of a trigger frame, wherein the trigger frame includes frequency resource information to be used for an uplink multi-user (UL MU) transmission, wherein the frequency resource information to be included in the trigger frame includes at least one of first type resource information used for random access and second type resource information used for scheduled access, wherein the random access is performed by the STA based on orthogonal frequency division multiple access (OFDMA), wherein the beacon frame further comprises a second field related to whether or not the trigger frame includes the first type resource information; receiving, from the AP by the STA, the trigger frame based on the first field; determining, by the STA, UL resource to be used for the UL MU transmission based on the first type resource information and the second type resource information; and performing, by the STA, the UL MU transmission based on the UL resource.

    Abstract: The present specification proposes a signal processing method for changing an operating mode for transmitting a PPDU in a wireless LAN system. Specifically, a first station receives, from the second station, indication information which indicates a change in an operating mode indicating a receiving channel bandwidth and a number of spatial streams supported by a second station during a TXOP interval. When the number of spatial streams and the receiving channel bandwidth decrease, the first station configures a PPDU for the second station by using the indication information after transmitting an ACK for the indication information. When the number of spatial streams and the receiving channel bandwidth increase, the first station configures a PPDU for the second station by using the indication information during a subsequent TXOP interval of the TXOP interval.
