Dynamic Spectrum Sharing for Multi-Standard Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication networks face inefficiencies in spectrum resource utilization due to simultaneous operation of multiple standards, such as 4G LTE and 5G NR, leading to cumbersome and inefficient spectrum sharing.
Innovation Solution
A communication service provider dynamically allocates spectrum resources between 5G and 6G technologies using common control signals and measurements, adjusting resource allocation based on traffic composition and QoS levels, employing a scheduler to manage shared spectrum efficiently across different frequency ranges and duplexing modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the same subcarrier spacing is used for both 4G LTE and 5G NR, then compatibility between standards is maintained, but spectrum efficiency is reduced
Solution Approach 1:
The patent implements dynamic spectrum sharing where the network can flexibly allocate spectrum resources between 4G LTE and 5G NR based on real-time traffic conditions. The spectrum allocation is not fixed but dynamically adjusted through coordination between eNB and gNB, allowing the system to transition from static to adaptive resource management that optimizes spectrum efficiency while maintaining compatibility.
Solution Approach 2:
The patent enables different subcarrier spacing configurations for 4G LTE and 5G NR to coexist in the same spectrum. By allowing parameter changes in subcarrier spacing (e.g., 15 kHz for LTE, 30/60 kHz for NR), the system can achieve better spectrum efficiency for 5G while maintaining LTE compatibility through proper parameter coordination and signaling.
2Adaptability or versatility
If multiple standards operate simultaneously, then gradual transition is enabled, but spectrum resource utilization becomes inefficient
Solution Approach 1:
The patent creates a universal spectrum sharing framework where the same spectrum resources can serve multiple standards (4G LTE and 5G NR) simultaneously. The shared spectrum pool is managed by coordination mechanisms that allow both standards to access common resources, enabling the spectrum to fulfill multiple functions and support gradual transition while improving overall utilization efficiency.
Solution Approach 2:
The patent merges the spectrum resource management of 4G LTE and 5G NR into a unified sharing framework. By combining previously separate spectrum allocations into a shared pool with coordinated access, the system enables multiple standards to operate together more efficiently, transforming from separate independent allocations to an integrated resource management approach.
3Ease of manufacture
If new technical standards are developed with fixed parameters, then implementation is simplified, but flexibility in spectrum sharing is reduced
Solution Approach 1:
The patent introduces dynamic parameter adjustment capabilities that allow the system to move from fixed to flexible configurations. While maintaining standardized implementations for ease of deployment, the system enables dynamic modification of spectrum allocation parameters, subcarrier spacing, and resource block assignments through coordination protocols, providing flexibility without sacrificing implementation simplicity.
Data Source
AI summary
Systems, methods, and computer-readable media are provided for facilitating dynamic spectrum allocation in wireless communication networks. Signal-related information is received from one or more user devices, and based on this information, a configuration for allocating wireless resources is determined. The allocation may involve adjusting communication parameters such as subcarrier spacing or resource block assignments in response to varying network or device conditions. Updated allocation information is communicated to the user devices through control signaling.
