Wireless Terminal Measurement Reporting Trigger Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in measurement reporting, as they often rely on single trigger quantities, leading to unnecessary reports or missed necessary reports due to insufficient mobility information and limited consideration of multiple metrics.
Innovation Solution
A method for a UE to receive multiple trigger quantities from a network, determining measurement report triggering conditions based on these quantities, and reporting results only when all conditions are met, including wireless channel information, load, and backhaul information, with adjustable inequality signs and thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single trigger quantity is used for measurement reporting, then the system complexity is reduced, but the measurement accuracy and reliability deteriorate due to insufficient mobility information
Solution Approach 1:
The patent segments the measurement reporting trigger into multiple independent trigger quantities (e.g., RSRP, RSRQ, RSSI) instead of using a single trigger quantity. Each trigger quantity is evaluated separately against its own threshold, allowing the system to maintain low complexity while improving measurement accuracy by considering multiple aspects of signal quality simultaneously
Solution Approach 2:
The patent transitions from a one-dimensional single-trigger approach to a multi-dimensional evaluation by introducing multiple trigger quantities with different thresholds. This dimensional expansion allows the system to capture diverse mobility scenarios (different signal conditions, interference levels, and quality requirements) without significantly increasing system complexity
2Measurement precision
If multiple trigger quantities are used for measurement reporting, then the measurement accuracy and reliability improve, but the device complexity increases
Solution Approach 1:
The patent changes the parameters of the measurement reporting system by introducing multiple trigger quantities (RSRP, RSRQ, RSSI) with independently configurable thresholds. This parameter expansion improves measurement precision by enabling fine-grained control over reporting triggers while maintaining manageable complexity through standardized evaluation procedures for each parameter
3Reliability
If multiple trigger quantities with multiple thresholds are used, then the reliability of measurement reporting improves, but the loss of time for evaluation increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple thresholds for each trigger quantity before the measurement reporting process begins. This allows the UE to quickly compare current measurements against predetermined thresholds without performing complex real-time calculations, thereby improving report reliability while minimizing evaluation time
