Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently utilizing non-contiguous frequency resources, particularly for UEs with varying bandwidth aggregation capabilities, leading to reduced spectrum utilization and co-existence issues.
Innovation Solution
A virtual cell configuration is introduced, allowing UEs with different bandwidth aggregation capabilities to communicate on a virtual cell formed by aggregating non-contiguous frequency resources, with bandwidth aggregation information and access information provided by the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If non-contiguous frequency resources are aggregated for virtual cell formation, then spectrum utilization efficiency is improved, but co-existence issues arise between UEs with different bandwidth aggregation capabilities
Solution Approach 1:
The patent segments UEs into different categories based on their bandwidth aggregation capabilities. Network entities provide different virtual cell configurations to different UE types, allowing each UE to access only the frequency resources it can aggregate. This segmentation resolves the co-existence issue by preventing incompatible UEs from interfering with each other while still enabling efficient use of non-contiguous spectrum for capable UEs.
Solution Approach 2:
The patent implements dynamic configuration where network entities adaptively assign different virtual cell configurations based on UE capabilities. The system dynamically determines which UEs can access which frequency resources, allowing flexible adaptation to different UE types while maintaining efficient spectrum utilization. This dynamic approach enables the system to optimize performance for each UE type without compromising overall co-existence.
2Adaptability or versatility
If virtual cell configuration is provided to all UEs, then communication flexibility is improved, but device complexity increases due to varying capability requirements
Solution Approach 1:
The patent applies local quality by providing different virtual cell configurations tailored to specific UE types rather than a universal configuration. Each UE type receives configuration parameters appropriate to its capabilities, reducing the complexity burden on individual devices. The network entity manages the complexity centrally by determining which configuration to provide to which UE type, rather than requiring each UE to handle all possible configuration scenarios.
