AI Technical Summary
Existing technologies struggle to effectively detect whether a user is within a specific distance of a wireless device without increasing costs or overhead, especially when operating in 5G frequency range 2, to avoid exceeding the maximum permissible exposure limit.
By utilizing the existing transmitters and receivers in wireless equipment, leakage signals and reflected signals can be distinguished by measuring the signature changes of the received signal relative to the transmitted signal, thus detecting the approach of a user and reducing the equipment power when a user is detected.
It enables accurate detection of user approach without increasing hardware costs, and reduces device power when a user is detected to ensure compliance with spectrum emission requirements and avoid interference with other users.
