Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems, particularly in 5G NR, lack the ability to predict and mitigate maximum power exposure (MPE) events effectively, leading to potential safety risks and inefficient power management due to reactive responses to detected MPE events.
Innovation Solution
Implementing a method and apparatus that enable the prediction of future MPE events and reporting these predictions to network nodes, allowing for proactive adjustments in communication characteristics to mitigate potential exposure risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If reactive response to detected MPE events is used, then safety compliance is maintained, but communication disruption increases and mitigation efficiency decreases
Solution Approach 1:
The system performs preliminary action by predicting future MPE events before they occur. The wireless device monitors current MPE conditions and projects them into the future to identify potential exposure events, then proactively adjusts transmission parameters in advance. This allows safety compliance to be maintained while avoiding communication disruptions that would occur with reactive responses.
Solution Approach 2:
The system applies preliminary anti-action by taking countermeasures before harmful MPE events occur. By predicting future exposure conditions and adjusting transmission power or beam directions in advance, the system prevents MPE violations before they happen, thereby maintaining safety compliance while keeping communications uninterrupted.
2Object-affected harmful factors
If transmission power is reduced to prevent MPE events, then safety compliance is improved, but communication quality and data rate deteriorate
Solution Approach 1:
The system uses preliminary action by predicting future MPE events and adjusting transmission parameters only when necessary. Instead of continuously reducing power, the system maintains full transmission power until a predicted MPE event occurs, then proactively adjusts parameters in advance. This minimizes the impact on data transmission rate while ensuring safety compliance.
Solution Approach 2:
The system applies dynamics by making transmission parameters adjustable and adaptive based on predicted MPE conditions. The wireless device dynamically modifies transmission power, beam direction, or other parameters in response to predicted events, allowing the system to maintain optimal performance during normal operation while ensuring safety when needed.
3Measurement precision
If continuous monitoring of MPE events is implemented, then detection accuracy is improved, but device complexity and energy consumption increase
Solution Approach 1:
The system uses preliminary action by performing prediction based on current monitoring data rather than requiring continuous real-time monitoring. The wireless device collects MPE measurements and uses this data to predict future events, reducing the need for constant monitoring while maintaining detection accuracy through proactive prediction algorithms.
Solution Approach 2:
The system applies self-service by having the wireless device perform its own MPE monitoring and prediction autonomously. The device uses its existing sensors and processing capabilities to monitor current conditions and predict future events, eliminating the need for additional external monitoring infrastructure and reducing overall system complexity.
