Terahertz Frequency Authorization for Coverage-Capacity Tradeoffs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems utilizing millimeter wave and terahertz frequency bands, the limited coverage range of access network devices results in low communication efficiency due to inefficient frequency resource allocation.
Innovation Solution
A method for frequency resource authorization that includes receiving and responding to requests for using target frequencies within available bands, including terahertz bands, by determining and allocating frequencies based on terminal capabilities and spatial positions, and adjusting bandwidth dynamically to improve communication efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If frequency resources are allocated in millimeter wave and terahertz bands, then communication capacity is improved, but coverage range is reduced
Solution Approach 1:
The patent segments the frequency spectrum into multiple bands including sub-6GHz, millimeter wave, and terahertz bands. Different bands are allocated to different terminals based on their capabilities and service requirements, allowing the system to simultaneously provide wide coverage in lower bands and high capacity in higher bands, thus resolving the contradiction between coverage range and communication capacity.
Solution Approach 2:
The patent introduces spatial dimension by deploying multiple access network devices in different locations and using beamforming technology. This allows the system to extend coverage range through spatial distribution while maintaining high communication capacity in terahertz bands through directional beams, effectively resolving the coverage-capacity trade-off.
2Speed
If access network devices use high-frequency bands, then communication speed is improved, but resource allocation efficiency deteriorates
Solution Approach 1:
The patent implements dynamic frequency resource allocation where access network devices continuously monitor terminal capabilities, channel conditions, and service requirements to dynamically adjust which frequency band (sub-6GHz, mmWave, or terahertz) is allocated to each terminal. This dynamic adaptation optimizes both communication speed and resource allocation efficiency by matching high-speed terahertz bands with appropriate terminals and services.
Solution Approach 2:
The patent changes the parameter of frequency band allocation from static to variable, allowing the system to select different frequency bands (sub-6GHz, millimeter wave, terahertz) based on real-time conditions. This parameter change enables the system to achieve high communication speed when using terahertz bands while maintaining overall resource allocation efficiency through intelligent selection and coordination across multiple bands.
