Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple remote units are deployed to provide multiple carriers, then wireless service capacity is improved, but device complexity and deployment cost increase
Solution Approach 1:
The patent combines multiple single-carrier radio points into a single multi-carrier radio point that can handle multiple carriers simultaneously. This merging approach provides the same wireless service capacity as multiple separate radio points but with reduced device complexity and lower deployment costs, as the multi-carrier radio point integrates the functionality of multiple units into one consolidated device.
Solution Approach 2:
The multi-carrier radio point is designed with multi-functionality to support multiple carriers and serve multiple cells through a single device. This universal design allows the radio point to perform the functions of multiple specialized single-carrier radio points, thereby improving wireless service capacity without increasing the number of deployed devices.
2Area of stationary object
If multiple radio points are deployed for multiple carriers, then coverage area is improved, but manual configuration effort increases
Solution Approach 1:
The multi-carrier radio point incorporates self-service capabilities through automated discovery processes and dynamic resource allocation. The system automatically performs carrier configuration, cell association, and resource management without requiring manual intervention for each carrier or cell. This self-configuration approach maintains comprehensive coverage while dramatically reducing the operational effort required compared to manually configuring multiple separate radio points.
3Ease of manufacture
If single carrier is supported per radio point, then resource allocation is simplified, but resource utilization efficiency decreases
Solution Approach 1:
The multi-carrier radio point implements dynamic resource allocation that allows processing resources and radio frequency modules to be flexibly assigned to different carriers and cells based on real-time demands. This dynamic approach enables the system to optimize resource utilization across multiple carriers simultaneously, improving productivity while maintaining manageable complexity through automated resource management mechanisms.

AI summary
One embodiment is directed to a multi-carrier radio point for use in a radio access network (RAN). The multi-carrier radio point is configured so that some of the processing and hardware resources provided by the radio point can be assigned to baseband units (BBUs) in a flexible manner. A single multi-carrier radio point can be used with multiple BBUs, where the processing and hardware resources used for the multiple BBUs need not be configured and used in the same way.
