1. A method in a wireless local area network (WLAN) system, the method comprising:
transmitting, by a transmitting station (STA), a first trigger frame requesting sensing to a receiving STA;
receiving, by the transmitting STA, a response frame to the first trigger frame from the receiving STA;
transmitting, by the transmitting STA, a second trigger frame requesting the first sensing frame to the receiving STA;
receiving, by the transmitting STA, the first sensing frame from the receiving STA; and
performing, by the transmitting STA, channel measurement based on the first sensing frame and obtaining sensing information,
wherein the transmitting STA and the receiving STA transmit and receive a radio signal in a 60 GHz band.
