Solution Overview
Problem
Existing wireless cellular communication systems, particularly in LTE-A, face challenges in accurately performing and reporting measurements for relay nodes separately from macro user equipment nodes, which affects radio link operations and resource management.
Innovation Solution
The implementation of a system and method that allows for separate measurement and reporting of relay node-related results, using a network architecture with a measuring and result reporting unit in relay nodes and a measurement configuration and result calculating unit in base stations, enabling distinct handling of relay node data within the LTE-A radio access network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If measurements are performed in the same way for relay nodes and macro user equipments, then the measurement process is simplified and standardized, but the accuracy and specificity of relay node measurement results are compromised
Solution Approach 1:
The patent segments the measurement reporting process by introducing a specific indicator that identifies whether a measurement result originates from a relay node or a macro user equipment. This segmentation allows the same measurement procedures to be used for both node types while enabling differentiated processing and analysis of the results, thus maintaining measurement standardization without sacrificing relay node measurement accuracy.
2Quantity of substance
If relay node measurement results are combined with macro user equipment results, then the overall network measurement dataset is enhanced, but the ability to analyze and optimize relay node specific performance is reduced
Solution Approach 1:
The patent introduces an intermediary indicator that acts as a marker within the measurement result data. This indicator serves as a mediator that allows relay node specific information to be preserved and identified within the combined measurement dataset. The indicator enables the network to distinguish and separately analyze relay node performance while maintaining the benefits of having a comprehensive combined measurement dataset.
3Reliability
If separate measurement reporting for relay nodes is implemented, then relay node specific optimization is enabled, but the measurement and reporting system complexity increases
Solution Approach 1:
The patent merges the relay node identification function into the existing measurement reporting framework by incorporating an indicator field into the current measurement result structure. This merging approach enables separate measurement reporting for relay nodes without creating a completely separate system, thus achieving relay node specific optimization while minimizing the increase in system complexity by leveraging existing infrastructure.
