Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing time-frequency-angular resources, particularly in scenarios involving multiple users and devices, where interference and resource allocation become complex issues.
Innovation Solution
The method involves selecting a first time-frequency-angular resource identified in the time domain, frequency domain, and azimuth angle domain, and transmitting a communication using this resource. This approach allows for more precise resource allocation and interference management by considering spatial dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional time-frequency resource allocation is used, then system implementation is simple, but resource utilization efficiency is low and interference management is insufficient
Solution Approach 1:
The patent extends traditional two-dimensional time-frequency resource allocation to three-dimensional time-frequency-angular resource allocation by adding the angular dimension. This allows resources to be identified and allocated based on time, frequency, and azimuth angle, enabling more precise resource utilization and interference management while maintaining manageable system complexity through structured resource element organization.
2Quantity of substance
If more users and devices are supported, then system capacity increases, but interference management becomes more complex
Solution Approach 1:
By adding the angular dimension to resource allocation, the patent enables spatial separation of users and devices. Resources can now be distinguished not only by time and frequency but also by azimuth angle, allowing the system to support more users simultaneously while managing interference through spatial differentiation. This dimensional extension provides additional degrees of freedom for interference mitigation.
3Reliability
If spatial dimensions are considered in resource allocation, then communication quality improves, but resource identification complexity increases
Solution Approach 1:
The patent segments the three-dimensional resource space into discrete resource elements, each identified by specific time, frequency, and angular parameters. This segmentation approach allows complex spatial resource allocation to be broken down into manageable units, improving communication quality through precise resource control while maintaining systematic resource identification methods that prevent overwhelming complexity.
