Abstract

A method of transmitting a sounding frame in a wireless local area network (WLAN) system, performed by a station in a first basic service set (BSS), and wireless apparatus supporting the method are provided. The method includes receiving, from an access point (AP), a request frame for requesting a transmission of a sounding frame, transmitting an indication frame indicating that a third party station in a second BSS sets a network allocation vector (NAV) in order for the third party station to prevent channel access for the NAV and transmitting the sounding frame in response to the request frame after transmitting the indication frame.
