Clustered User Communication Links for Low-Latency Resource Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in achieving ultra-reliable and low-latency communication for massive users due to limited resources, leading to competition for resource allocation and increased waiting latency, which is not conducive to high reliability and low latency requirements in scenarios like drone networks and Internet of Vehicles.
Innovation Solution
A multi-layer communication architecture is implemented, dividing user devices into device clusters with master and slave user devices, allocating non-competitive and competitive resources in a grant-free access manner, utilizing both multi-layer communication links and direct links to facilitate efficient resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If users compete for limited communication resources, then resource allocation efficiency improves, but communication reliability deteriorates and waiting latency increases
Solution Approach 1:
The patent segments users into device clusters with master user devices and slave user devices. Non-competitive resources are allocated to first links between master and slave devices within clusters, while competitive resources are allocated to second links. This segmentation resolves the contradiction by creating dedicated resource pools for different link types, ensuring reliable communication for cluster members while maintaining overall system efficiency.
Solution Approach 2:
The patent applies local quality by allocating different resource types to different link categories. First links (within-cluster) receive non-competitive resources guaranteeing reliability, while second links (inter-cluster or direct) use competitive resources for efficiency. This differentiated resource allocation strategy allows each link type to have optimized resource characteristics suited to its communication requirements.
2Quantity of substance
If users wait for idle resources, then resource utilization improves, but latency increases and low-latency requirements cannot be met
Solution Approach 1:
The patent implements preliminary action by pre-allocating non-competitive resources to first links between master and slave user devices within device clusters. This advance resource assignment eliminates the need for devices to wait for idle resources, as dedicated resources are already reserved for these communication links, thereby reducing waiting latency while maintaining high resource utilization through systematic allocation.
3Quantity of substance
If limited resources are shared among massive users, then system capacity improves, but communication reliability deteriorates
Solution Approach 1:
The patent segments the massive user base into multiple device clusters, each with its own master user device and allocated non-competitive resources. This segmentation allows the system to scale capacity by adding clusters while maintaining reliability within each cluster through dedicated resource allocation. The hierarchical structure enables massive user support without sacrificing individual communication reliability.
Solution Approach 2:
The patent introduces a hierarchical dimension to resource allocation by creating multiple levels: device clusters, master user devices, and communication links. This dimensional organization transforms the flat resource competition model into a structured hierarchy where resources are allocated at different levels, enabling the system to accommodate massive users while preserving communication reliability through multi-layered resource management.
