Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multi-carrier access is implemented to support diverse traffic scenarios and high data demands, then network capacity and data rates are improved, but network complexity and resource management difficulty increase
Solution Approach 1:
The patent segments the radio access network into multiple independent carriers, each optimized for specific traffic scenarios (e.g., enhanced mobile broadband, massive machine type communication, ultra-reliable low latency communication). This allows the network to handle diverse traffic demands through specialized carriers while maintaining manageable complexity through modular architecture.
Solution Approach 2:
The patent introduces a centralized controller as an intermediary that manages resource allocation across multiple carriers. This controller abstracts the complexity of multi-carrier coordination from individual network elements, enabling efficient resource management without requiring complex peer-to-peer interactions between network components.
2Adaptability or versatility
If dynamic resource allocation is implemented based on application requirements, then spectrum utilization is improved, but control overhead and processing requirements increase
Solution Approach 1:
The patent implements dynamic resource allocation where network resources are continuously adjusted based on real-time application requirements and traffic conditions. The system transitions from static carrier configurations to dynamic resource assignment, allowing spectrum to be reallocated among carriers based on current network demands and service priorities.
Solution Approach 2:
The patent incorporates feedback mechanisms where the centralized controller continuously monitors network conditions, application requirements, and resource utilization across carriers. Based on this feedback, the controller dynamically adjusts resource allocation decisions, creating a closed-loop system that optimizes spectrum utilization while adapting to changing conditions.
3Reliability
If network slicing is implemented to ensure efficient traffic management, then quality of service is improved, but network configuration complexity increases
Solution Approach 1:
The patent divides the network into multiple virtual slices, each dedicated to specific service requirements (e.g., low latency, high bandwidth, massive connectivity). Each slice is configured with appropriate resources and parameters tailored to its specific quality of service requirements, allowing differentiated service delivery without requiring complex per-flow configuration.
Solution Approach 2:
The patent creates universal carrier configurations that can serve multiple service types through slicing. Instead of creating dedicated physical infrastructure for each service, the system uses a single physical carrier that can be virtually sliced into multiple logical channels, each with appropriate quality of service characteristics, thereby reducing overall network configuration complexity.

AI summary
A framework of abstraction of new and existing 5G radios can enhance capabilities of new and existing micro radios and other short range radio technologies to enable intelligent service delivery, dynamic access learning capability, and network slicing over 5G access networks. Enhancing layer communication for both control and user plane can be tunneled through the hosting layer and exploit a common transport provided by the hosting layer. The tunneling through the hosting layer can also enable the enhance capabilities to access the same radio management functions and can be orchestrated by the same core function. The framework for abstraction of the resources can be used to provide dynamic sharing of the resources and then be divided amongst different carriers.
