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: An indoor air quality control method using an intelligent air cleaner is disclosed. An indoor air quality control method using an intelligent air cleaner according to an embodiment of the present invention can predict indoor dust concentration progress on the basis of output values of a learning model having received dust concentration data as input values when the dust concentration data of an indoor place where the air cleaner is located is received from the air cleaner, and determine whether ventilation is required by comparing the predicted progress with outside dust concentration data received from the Meteorological Administration server. Accordingly, indoor dust concentration changes can be predicted and an appropriate ventilation time can be recommended. The intelligent air cleaner and the indoor air quality control method using the same of the present invention can be associated with artificial intelligence modules, devices related with the 5G service, and the like.

Abstract: In a wireless communication system supporting Bluetooth communication, an in-flight entertainment (IFE) device may perform scanning for a first Bluethooth low energy (BLE) device and a first Bluetooth basic rate/enhanced data rate (BR/EDR) device. The scanning for the first BLE device and the first Bluetooth BR/EDR device may be performed in a time division (TD) manner performed in different time intervals. The scanning for the first BLE device may include a step of receiving a first advertising signal of the first BLE device. The scanning for the first Bluetooth BR/EDR device may include a step of transmitting a scan signal and receiving a first scan response signal from the first Bluetooth BR/EDR device, by the IFE device.

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.
