Method for transmitting and receiving wake-up packet in wireless lan system, and apparatus therefor

A method for a wireless Local Area Network (WLAN), the method comprising:

• transmitting, by a Wake-Up Radio (WUR) station (STA) including a Primary Connectivity Radio (PCR) receiver receiving a WLAN packet and a WUR receiver receiving a WUR packet, an association request including WUR capability information of the WUR STA to an access point (AP), wherein the WUR packet is modulated based on On-Off Keying (OOK) scheme;
• in response to the association request, receiving, by the WUR STA, an association response including an association identifier (AID) from the AP;
• transmitting, by the WUR STA to the AP, a mode request to enter a WUR mode including a time duration in which the WUR STA receives the WUR packet;
• and
• in response to the mode request, receiving, by the WUR STA to the AP, a mode response to enter the WUR mode, wherein the mode response includes a WUR ID which identifies an intended receiver of the WUR packet.

A Wake-Up Radio (WUR) station (STA) in a wireless Local Area Network (WLAN), the WUR STA comprising:

• a Primary Connectivity Radio (PCR) receiver receiving a WLAN packet;
• a WUR receiver receiving a WUR packet;
• and
• a processor coupled to the PCR receiver and the WUR receiver and configured to:
• transmit an association request including WUR capability information of the WUR STA to an access point (AP), wherein the WUR packet is modulated based on On-Off Keying (OOK) scheme;
• in response to the association request, receive an association response including an association identifier (AID) from the AP;
• transmit a mode request to enter a WUR mode including a time duration in which the WUR STA receives the WUR packet;
• and
• in response to the mode request, receive a mode response to enter the WUR mode, wherein the mode response includes a WUR ID which identifies an intended receiver of the WUR packet.
