Dynamic Numerology Allocation for 5G Resource Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G communication systems, existing resource allocation methods fail to effectively utilize physical resources with different characteristics, such as varying OFDM subcarrier widths, leading to inefficient data transmission and control signal handling.
Innovation Solution
A method where user equipment (UE) determines the appropriate numerology for receiving control signals and data by reporting FFT processing capabilities to the base station, allowing for the allocation of resources based on multiple types of multicarrier parameter numerology, and adjusts operation modes to optimize data transmission according to latency and resource availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single type of numerology is used for resource allocation, then the device complexity is reduced, but the adaptability to different resource characteristics deteriorates
Solution Approach 1:
The patent implements dynamic numerology selection where the base station determines different numerology types for control signals and data based on channel conditions, traffic requirements, and resource availability. This allows the system to adapt resource allocation to varying characteristics without requiring complex static configurations, resolving the contradiction between simplicity and adaptability.
Solution Approach 2:
The patent changes the numerology parameter (OFDM subcarrier width) dynamically based on resource characteristics. By allowing different numerology types for different resources rather than using a fixed single type, the system achieves adaptability to diverse resource characteristics while maintaining manageable complexity through standardized parameter selection rules.
2Productivity
If multiple types of numerology are allocated for different resources, then the resource utilization efficiency is improved, but the device complexity increases
Solution Approach 1:
The patent segments resources into different numerology types (first type for control signals, second type for data) with distinct characteristics. This segmentation allows optimized processing for each resource type while the UE only needs to handle the specific segments assigned to it, managing complexity through division rather than requiring simultaneous processing of all numerology types.
Solution Approach 2:
The patent creates a universal resource allocation framework where the base station manages multiple numerology types but the UE operates with a simplified view, receiving resources according to its capability. This multi-functionality allows the system to support diverse numerologies while keeping individual UE complexity manageable through capability-based allocation.
3Device complexity
If FFT processing capability is limited to one at a time, then the device complexity is reduced, but the productivity deteriorates
Solution Approach 1:
The patent implements dynamic operation modes where the UE can switch between single-FFT and multi-FFT processing based on resource allocation and capability. When multiple numerology types are allocated, the UE dynamically activates additional FFT processing capabilities, allowing productivity to scale with resource needs while maintaining low complexity when resources are limited.
