Heterogeneous Network Control via Dynamic Measurement Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, the increasing bandwidth requirements necessitate the use of both licensed and unlicensed frequency spectra by user equipment (UE), but without coordination, it becomes challenging for multiple UEs to share the same unlicensed spectrum effectively, leading to inefficiencies in channel measurement and reporting processes.
Innovation Solution
A method is introduced to control heterogeneous networks by transmitting configuration messages with specific measurement and report rules (MRR) that include varying intervals for channel measurement and reporting, allowing UEs to optimize their reporting based on their distance from the LAA Node and environmental interference levels, thereby reducing signaling overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If UEs perform frequent channel measurement and reporting in unlicensed spectrum, then channel sharing efficiency improves, but signaling overhead increases
Solution Approach 1:
The patent applies dynamics by making the measurement and reporting intervals variable rather than fixed. The base station configures different measurement intervals and reporting intervals based on UE distance from the LAA node and environmental interference levels. This dynamic adjustment optimizes channel sharing efficiency while minimizing signaling overhead for each specific scenario.
Solution Approach 2:
The patent implements local quality by tailoring measurement and reporting configurations to individual UEs based on their specific conditions. Each UE receives customized measurement intervals and reporting intervals according to its distance from the LAA node and local interference environment, rather than applying a uniform configuration to all UEs.
2Measurement precision
If UEs closer to LAA node report channel conditions frequently, then network control accuracy improves, but resource consumption increases
Solution Approach 1:
The patent applies local quality by differentiating measurement and reporting requirements based on UE location. UEs closer to the LAA node, which have better signal conditions and higher relevance to network decisions, are configured with shorter measurement and reporting intervals. UEs farther away use longer intervals, reducing their energy consumption while maintaining adequate network control accuracy.
Solution Approach 2:
The patent implements parameter changes by dynamically adjusting measurement intervals and reporting intervals based on UE distance and environmental conditions. This allows the system to optimize the balance between measurement precision and energy consumption by changing these parameters according to specific operational contexts.
