Abstract

In a wireless local area network (LAN) system, a transmission STA may generate capability information related to WLAN sensing. The capability information may comprise a common part and an individual part. The common part may comprise sensing support band information including information related to whether WLAN sensing performed in a sub 7 GHz band is supported, and information related to whether WLAN sensing performed in a 60 GHz band is supported. The individual part may comprise, on the basis of the sensing support band information, at least one of capability information for WLAN sensing performed in the sub 7 GHz band, and capability information for WLAN sensing performed in the 60 GHz band. The transmission STA may transmit the capability information to a reception STA.
