Dynamic SUO Configuration for Dual Connectivity Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In dual connectivity networks, particularly in 4G/5G environments, conventional Single Uplink Operation (SUO) configurations lead to inter-technology interference and inefficient resource allocation due to static TDM configurations, resulting in capped throughput and poor alignment with Dual-Connectivity Uplink demand.
Innovation Solution
An algorithm is implemented at a central node within the Core Network to dynamically adjust TDM LTE/5G configurations based on aggregated TX power measurements, interference analysis, traffic profiles, and UE capabilities, optimizing TDD DL/UL configurations to minimize inter-band interference and align with IRAT demand and QoS requirements.

Engineering Contradiction Analysis
1Object-affected harmful factors
If static TDM configurations are used for Single Uplink Operation, then inter-technology interference is reduced, but throughput is capped and resource allocation is inefficient
Solution Approach 1:
The patent implements dynamic TDM configuration where the network node continuously monitors aggregated TX power measurements, interference levels, and traffic profiles, then adjusts the TDM LTE/5G configuration in real-time. This replaces static configurations with adaptive ones that optimize both interference reduction and throughput based on current network conditions.
Solution Approach 2:
The system changes key parameters including TDM configuration patterns, TX power levels, and resource allocation ratios dynamically based on monitored conditions. The network node adjusts these parameters to balance interference mitigation with throughput optimization, rather than using fixed parameter sets.
2Object-affected harmful factors
If TDM configuration is optimized for interference reduction, then inter-band interference decreases, but alignment with Dual-Connectivity Uplink demand deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the network node continuously monitors traffic profiles, UE capabilities, and interference levels, then uses this feedback to adjust TDM configurations. This closed-loop system ensures configurations remain aligned with actual Dual-Connectivity Uplink demand while maintaining interference reduction.
Solution Approach 2:
The system dynamically adapts TDM configurations based on real-time monitoring of traffic profiles and UE capabilities. This allows the network to maintain optimal alignment with varying IRAT demand patterns while continuously managing inter-band interference through adaptive adjustment.
3Power
If aggregated TX power is increased for 5G, then 5G performance improves, but LTE uplink coverage is reduced
Solution Approach 1:
The patent implements periodic monitoring and adjustment of TX power allocation between LTE and 5G. The network node continuously measures aggregated TX power and dynamically adjusts the split between technologies, allowing 5G to receive higher power when needed while ensuring LTE maintains sufficient coverage through periodic reallocation.
Solution Approach 2:
The system dynamically changes TX power parameters for both LTE and 5G based on monitored conditions. When 5G performance needs improvement, the network increases 5G TX power allocation; when LTE coverage becomes constrained, it reallocates power to maintain the P_LTE + P_NR = P_powerclass balance.
