Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The preconfiguration of transmission resources for pilot signals in communication systems lacks flexibility, leading to inflexibility and resource waste.
Innovation Solution
A method where resource configuration information for pilot signals is dynamically included in a message triggering their transmission, allowing for flexible resource allocation only when needed, thereby avoiding preconfigured resource constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If preconfiguration of transmission resources is used for pilot signals, then resource allocation is simplified, but flexibility is reduced and resource waste occurs
Solution Approach 1:
The patent applies dynamics by transitioning from static preconfigured resources to dynamic resource allocation. The network device dynamically determines pilot signal transmission resources based on real-time channel conditions and traffic requirements, allowing the system to adapt flexibly while maintaining efficient resource management through centralized control.
2Ease of manufacture
If preconfiguration of transmission resources is used for pilot signals, then resource allocation is simplified, but resource waste increases
Solution Approach 1:
The patent implements feedback mechanisms where the network device monitors channel conditions and pilot signal reception quality, then uses this feedback to dynamically adjust resource allocation for subsequent pilot transmissions. This closed-loop approach ensures resources are allocated only when needed and at optimal levels, eliminating waste while maintaining simple centralized management.
3Adaptability or versatility
If dynamic resource allocation is implemented for pilot signals, then flexibility is improved, but system complexity increases
Solution Approach 1:
The patent introduces the network device as an intermediary that centralizes the complexity of dynamic resource allocation. The network device receives channel state information, determines optimal pilot transmission resources, and communicates these allocations to terminal devices. This intermediary approach distributes complexity to the network side while keeping terminal devices simple, achieving flexibility without overwhelming system complexity.
