Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing frequency resources, particularly in the terahertz band, where severe path loss and atmospheric absorption occur, necessitating advanced technologies for securing signal transmission distance and improving spectral efficiency.
Innovation Solution
The method involves a network entity that assigns dynamic frequency channels by identifying device clusters and allocating frequency channels from a set assigned to the cluster, allowing for efficient sharing and utilization of frequency resources across multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If frequency channels are assigned to individual devices, then each device can operate independently, but frequency resource efficiency deteriorates due to inability to share channels dynamically
Solution Approach 1:
The patent merges multiple devices into device clusters that share common frequency channel sets. Instead of assigning channels individually to each device, the network entity assigns frequency channel sets to clusters of devices, allowing them to share resources dynamically while maintaining independent operation through cluster-based management.
Solution Approach 2:
The patent implements dynamic frequency channel assignment where devices can transition between different frequency channels based on real-time network conditions, device requirements, and cluster configurations. The network entity dynamically adjusts channel assignments within clusters rather than using static individual assignments.
2Productivity
If frequency channels are shared among multiple devices, then frequency resource efficiency improves, but device complexity increases due to coordination requirements
Solution Approach 1:
The patent introduces a network entity as an intermediary that manages frequency channel assignments for device clusters. This intermediary handles the complexity of coordination, conflict resolution, and dynamic assignment, while devices within clusters follow simpler cluster-based assignment rules without needing complex peer-to-peer coordination mechanisms.
3Productivity
If dynamic frequency assignment is implemented, then spectral efficiency improves, but system complexity increases due to real-time management requirements
Solution Approach 1:
The patent segments the frequency spectrum into multiple frequency channels and organizes devices into clusters, each with assigned channel sets. This segmentation allows dynamic assignment at the cluster level rather than requiring system-wide real-time management, reducing overall system complexity while maintaining spectral efficiency through flexible channel allocation within segments.
4Productivity
If device clusters are formed for frequency sharing, then frequency resource efficiency improves, but loss of information increases due to cluster management overhead
Solution Approach 1:
The patent implements feedback mechanisms where devices report their frequency channel usage, performance metrics, and cluster conditions to the network entity. This feedback enables the network entity to make informed dynamic assignment decisions, adjust cluster configurations, and prevent information loss by continuously updating frequency assignment information based on actual system state.
