Abstract: Proposed are a method and device for performing wireless sensing in a wireless LAN system based on wireless sensing. Specifically, a wireless apparatus collects CSI data and lifelog. The wireless apparatus performs learning and prediction on the basis of the CSI data to acquire a first user estimation result. When the first user estimation result is at most a threshold value, the wireless apparatus predicts a second user estimation result on the basis of the lifelog.

Abstract: A method and apparatus for performing wireless sensing in a wireless LAN system on the basis of wireless sensing are proposed. Specifically, a wireless device determines a first time for collecting empty data. The wireless device collects empty data during the first time. The empty data is a wireless signal when there is no user in a preset space.

Abstract: Proposed is a method and device for generating a user identification model on the basis of wireless sensing in a wireless LAN system. Specifically, a user identification apparatus discovers a PED and acquires identification information about the PED. The user identification apparatus collects data and pre-processes the collected data on the basis of the identification information about the PED. The user identification apparatus generates a user identification model by learning the pre-processed data.
