BLER Measurement Segmentation for MBMS Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current MBMS technologies face challenges in accurately measuring and reporting block error rates in multicast broadcast single-frequency networks, particularly due to dynamic traffic patterns and time limitations, which affect the validity and reliability of measurement data.
Innovation Solution
User equipment performs block error rate measurements, maps them to categories, and associates a time limit, determining the validity of the measurements, which are then logged and reported, allowing for efficient data storage and communication, even under dynamic conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If block error rate measurements are performed continuously to ensure reliable coverage assessment, then measurement reliability is improved, but device complexity and energy consumption increase
Solution Approach 1:
The patent segments BLER measurements into different measurement types (first type and second type) with different complexities. First type measurements are performed continuously with higher reliability, while second type measurements are performed less frequently with lower complexity. This segmentation allows the system to maintain overall measurement reliability while reducing average device complexity and energy consumption.
Solution Approach 2:
The patent applies partial action by performing full BLER measurements only when necessary (first type measurements), and using simplified measurement approaches for routine monitoring (second type measurements). This partial action strategy maintains sufficient measurement reliability for coverage assessment while significantly reducing the complexity and energy burden of continuous full measurements.
2Measurement precision
If detailed BLER measurement data is stored and reported to assess coverage accurately, then measurement precision is improved, but data storage requirements increase
Solution Approach 1:
The patent extracts and reports only the most essential BLER measurement results and coverage assessment data to the network, rather than storing and transmitting all raw measurement data. This extraction approach maintains measurement precision for coverage assessment while significantly reducing the volume of data that needs to be stored in the user equipment.
Solution Approach 2:
Instead of storing all measurement data and then selecting what to report, the patent inverts the approach by determining what essential data is needed for coverage assessment and only storing and reporting that specific subset. This inversion minimizes storage requirements while maintaining the precision needed for accurate coverage evaluation.
