User Equipment Transmission Power Control via Sensor-Based Radiation Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mmWave wireless networks, User Equipment (UE) experiences excessive exposure to radiation due to high transmission power, exceeding regulatory limits, especially in dual transmission scenarios, posing health risks that existing technologies have not adequately addressed.
Innovation Solution
The UE employs sensors to detect user interactions and adaptively calculate maximum transmission power, ensuring compliance with regulatory limits by adjusting power levels based on user proximity and position, using a processor to manage transmission power and estimate power headroom reports.

Engineering Contradiction Analysis
1Productivity
If beam forming and high transmission power are used to increase data rates and transmission distance, then network performance is improved, but user exposure to radiation exceeds regulatory limits
Solution Approach 1:
The patent implements dynamic transmission power adjustment by continuously monitoring user presence through sensors (proximity sensors, cameras, depth sensors) and adapting the transmission power level in real-time. When a user is detected within a predetermined distance, the system dynamically reduces transmission power to comply with regulatory limits while maintaining high data rates when users are absent
Solution Approach 2:
The system changes the transmission power parameter based on detected user conditions. The processor determines whether to transmit at full power or reduced power by evaluating sensor data about user proximity and position, thereby adjusting the radiation exposure parameter while maintaining network performance when appropriate
2Object-affected harmful factors
If transmission power is reduced to comply with radiation limits, then user safety is improved, but network performance deteriorates
Solution Approach 1:
The system employs periodic sensing and power adjustment cycles. The processor periodically activates sensors to detect user presence, evaluates the detected conditions, and adjusts transmission power accordingly. This periodic action allows the system to maintain high power (and thus high data rates) during periods when no users are present while ensuring safety when users are detected
Solution Approach 2:
The transmission power is made dynamic rather than static, allowing the system to switch between high-power mode (for optimal data rates) and low-power mode (for safety compliance) based on real-time user presence detection, thereby resolving the trade-off between performance and safety
3Object-affected harmful factors
If sensors are added to detect user interactions, then radiation compliance is improved, but device complexity increases
Solution Approach 1:
The patent leverages existing multi-functional components in modern UEs. Cameras, depth sensors, and proximity sensors are already present for other purposes (photography, augmented reality, user interface). The invention repurposes these existing sensors for radiation compliance monitoring, thereby avoiding the need to add dedicated hardware and minimizing additional system complexity
Solution Approach 2:
The system uses the UE's own existing sensor suite to monitor user presence and self-regulate transmission power. The processor within the UE performs the detection and control functions using already-present hardware, eliminating the need for external monitoring devices or complex additional control systems
