Solution Overview
Problem
Existing multi-mode radio units face challenges in efficiently managing communication resources, particularly in 5G networks, due to high throughput requirements and latency constraints in the 7.2 split mode, which can lead to network congestion and coverage issues.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the radio unit operates in 7.2 split mode, then centralized resource management and simplified RF planning are achieved, but high throughput requirements and latency constraints cause network congestion and coverage issues
Solution Approach 1:
The radio unit dynamically switches between 7.2 split mode and full gNB mode based on real-time network conditions, front-haul link quality, and traffic load. This dynamic adaptation allows the system to maintain centralized resource management when conditions permit while switching to full gNB mode when latency or throughput constraints threaten coverage and reliability.
Solution Approach 2:
The system changes operational parameters by switching between two distinct modes: 7.2 split mode (with centralized management) and full gNB mode (with distributed management). The switching decision is based on monitoring parameters such as front-haul link quality, latency measurements, and traffic load, allowing the system to adapt to changing network conditions and prevent congestion-induced coverage issues.
2Ease of manufacture
If the radio unit operates in 7.2 split mode, then simplified RF planning is achieved, but high throughput requirements lead to network congestion under high load
Solution Approach 1:
The radio unit dynamically adjusts its operational mode based on traffic load and front-haul capacity. When traffic demand exceeds what the front-haul link can handle in 7.2 split mode, the system switches to full gNB mode, which distributes processing and reduces the throughput burden on the front-haul connection, thereby preventing network congestion while maintaining simplified RF planning capabilities when conditions allow.
Solution Approach 2:
The radio unit is designed to perform multiple functions by supporting both 7.2 split mode operation (with centralized resource management and simplified RF planning) and full gNB mode operation (with distributed processing). This multi-functionality allows the same hardware to adapt to different network conditions and capacity requirements, ensuring both ease of deployment and high throughput capability when needed.
3Productivity
If the radio unit switches between modes dynamically, then resource utilization is optimized and coverage is maintained, but system complexity increases
Solution Approach 1:
The mode switching mechanism employs feedback from monitored parameters including front-haul link quality, latency measurements, and traffic load. The radio unit continuously monitors these parameters and automatically switches modes based on pre-defined thresholds and conditions, optimizing resource utilization and maintaining coverage without requiring complex manual configuration or intervention. The feedback-driven approach simplifies the control logic compared to static configurations.
Solution Approach 2:
The radio unit performs self-service by autonomously monitoring its own operational parameters, evaluating front-haul link conditions, and making mode switching decisions without external intervention. This self-service capability optimizes resource utilization and maintains coverage adaptively, while the automated nature of the process prevents the system complexity from escalating despite the dynamic switching functionality.

AI summary
A multi-mode radio unit, and more specifically providing a multi-mode radio unit having a 7.2 split mode and a full gNodeB (gNB) mode may be provided. A 7.2 split mode may be executed at a Multi-Mode Radio Unit (MMRU). Next a metric associated with a front-haul link between the MMRU and a Distributed Unit (DU) may be monitored. The metric may be compared to a first threshold, and when the metric is above the first threshold, the MMRU may be caused to switch from the 7.2 split mode to a full gNodeB (gNB) mode.
