Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless telecommunication systems face challenges in meeting stringent quality requirements such as ultra-reliable and low-latency communications (URLLC) due to insufficient reactive resource management, particularly in dynamic environments where mobile devices and surroundings change rapidly.
Innovation Solution
Implementing an apparatus with detecting means to capture dated images of a geographical zone, analyze object properties, and predict future visibility to proactively adapt radio connections, including features like video cameras, thermal detectors, and processing means to determine object trajectories and visibility, enabling proactive adjustments in transmission power, coding rate, and handovers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If reactive resource management is used to adapt transmission parameters, then resource efficiency is improved, but reliability under dynamic conditions deteriorates
Solution Approach 1:
The system performs preliminary actions by predicting future radio connection quality based on current image analysis and object trajectories. Instead of waiting for feedback to detect degradation, the base station proactively identifies objects that will enter the beam and pre-adapts transmission parameters before the actual quality deterioration occurs, thus maintaining reliability while avoiding unnecessary resource consumption.
Solution Approach 2:
The system implements a feedback loop where image data from the geographical zone is continuously analyzed to detect objects and their movements. This visual feedback is combined with trajectory prediction to generate anticipatory control decisions, creating a closed-loop system that adapts transmission parameters based on predicted future states rather than past performance.
2Reliability
If transmission power is increased to guarantee URLLC quality, then reliability is improved, but energy consumption increases
Solution Approach 1:
The system dynamically adapts transmission power based on predicted radio connection quality rather than maintaining a static high power level. By analyzing object trajectories and predicting when quality degradation will occur, the base station adjusts power levels in real-time, consuming high power only when necessary to maintain URLLC quality and reducing power when conditions permit, thus resolving the contradiction between reliability and energy consumption.
3Device complexity
If reactive adaptation based on feedback is used, then device complexity is reduced, but response time to quality changes increases
Solution Approach 1:
The system performs preliminary adaptation actions by predicting future radio connection quality based on object trajectories detected in image data. Instead of waiting for feedback to indicate quality degradation, the base station proactively adjusts transmission parameters before the actual quality change occurs, significantly reducing the effective response time while maintaining manageable system complexity through the use of image processing and trajectory prediction algorithms.
