Radio Node Measurement Compensation for Environmental Conditions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication standards define measurement and performance requirements for radio nodes under static conditions, ignoring actual environmental conditions, which leads to inaccurate measurements and degraded radio procedures due to environmental-induced errors.
Innovation Solution
Implement a method in radio nodes and network nodes to dynamically account for environmental conditions by determining and compensating for factors such as temperature, voltage, and vibration, configuring measurements and operations accordingly, and associating measurement results with environmental conditions for improved accuracy.

Engineering Contradiction Analysis
1Measurement precision
If static measurement requirements are defined for radio nodes under fixed conditions, then device complexity is reduced and ease of manufacture is improved, but measurement precision deteriorates under varying environmental conditions
Solution Approach 1:
The patent applies dynamics by transitioning from static measurement requirements to dynamic measurement configurations that adapt to environmental conditions. The network node determines environmental conditions (temperature, voltage, vibration) and configures measurements accordingly, allowing the measurement system to change its behavior based on real-time conditions rather than relying on fixed pre-defined requirements.
Solution Approach 2:
The patent changes measurement parameters (bandwidth, periodicity, time intervals) based on environmental condition parameters. When environmental conditions change, the network node adjusts measurement parameters to maintain measurement precision, directly applying the parameter changes principle to resolve the contradiction between measurement accuracy and system complexity.
2Measurement precision
If environmental condition monitoring and dynamic compensation are implemented, then measurement precision is improved under varying conditions, but device complexity increases
Solution Approach 1:
The network node acts as an intermediary that receives environmental condition information from sensors and translates it into appropriate measurement configurations. This intermediary function centralizes the complexity management, allowing individual radio nodes to maintain simpler devices while the network node handles the complex decision-making about measurement configurations based on environmental conditions.
Solution Approach 2:
The system implements feedback by continuously monitoring environmental conditions and using this information to adjust measurement configurations. The network node receives environmental data, processes it to determine appropriate measurement parameters, and applies these configurations dynamically, creating a closed-loop feedback system that maintains measurement precision without requiring complex local decision-making at each radio node.
3Measurement precision
If measurement configurations are adapted to environmental conditions, then measurement precision is improved, but loss of time increases due to dynamic reconfiguration
Solution Approach 1:
The network node determines environmental conditions in advance of performing measurements and pre-configures the appropriate measurement parameters. By determining the required measurement configuration before actual measurement takes place, the system avoids time-consuming reconfiguration during the measurement process itself, thus maintaining measurement precision while minimizing time loss.
