Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If radio resources are allocated statically per CSP, then each CSP can guarantee its spectrum requirements, but resource utilization efficiency deteriorates and installation costs increase
Solution Approach 1:
The patent segments radio resources into two distinct types: dedicated resources allocated to specific CSPs and shared resources available to multiple CSPs. This segmentation allows the system to guarantee spectrum requirements for critical CSPs while efficiently utilizing resources from multiple CSPs, thereby resolving the contradiction between reliability and productivity.
Solution Approach 2:
The shared radio unit serves multiple CSPs simultaneously, performing multiple functions for different communication service providers. This multi-functionality enables efficient resource utilization across CSPs while maintaining the ability to provide guaranteed spectrum to individual CSPs through dedicated resources, thus resolving the contradiction.
2Reliability
If multiple radio units are deployed to serve different CSPs, then each CSP gets dedicated service, but device complexity and installation footprint increase
Solution Approach 1:
The patent merges multiple radio units into a single shared radio unit that serves multiple CSPs. This consolidation reduces the installation footprint and overall system complexity while maintaining dedicated service quality for each CSP through the resource allocation mechanisms, thereby resolving the contradiction between reliability and device complexity.
Solution Approach 2:
The shared radio unit is designed as a universal platform capable of serving multiple CSPs simultaneously. This multi-functional design eliminates the need for separate dedicated radio units for each CSP, reducing installation footprint and complexity while preserving CSP service dedication through logical resource separation.
3Power
If radio units are dimensioned for peak rates, then maximum spectrum capacity is achieved, but resource allocation becomes inefficient during non-peak periods
Solution Approach 1:
The patent segments capacity into dedicated resources for peak rate guarantees and shared resources for efficient utilization. During peak periods, dedicated resources ensure maximum capacity for requiring CSPs. During non-peak periods, shared resources are allocated to CSPs with lower demand, thereby maintaining both peak capacity and overall allocation efficiency.
Solution Approach 2:
The system dynamically allocates shared resources to different CSPs based on real-time demand patterns. This dynamic resource management allows the system to optimize productivity during non-peak periods while maintaining the capability to deliver peak rates when needed, resolving the contradiction between power and productivity.
4Ease of manufacture
If existing sharing solutions are used, then installation costs are reduced, but run-time complexity and protocol coordination requirements increase
Solution Approach 1:
The patent segments resource management into simple static allocations for dedicated resources and a centralized dynamic allocation mechanism for shared resources. This segmentation simplifies the overall system architecture by separating guaranteed service provisioning from efficient resource sharing, thereby reducing run-time complexity while maintaining low installation costs.
Solution Approach 2:
The patent introduces a resource allocation mechanism that acts as an intermediary between CSPs and the shared radio unit. This intermediary manages the complexity of protocol coordination and run-time resource management, allowing CSPs to simply declare their needs while the intermediary handles the complex coordination, thus reducing overall system complexity.

AI summary
A method, system and apparatus are disclosed. A radio resource handler, RRH, configured to communicate at least with a plurality of baseband units and a first shared radio unit that is shared by the plurality of baseband units is provided. The RRH receives a first resource indication associated with the first shared radio unit indicating a plurality of dedicated resources and a plurality of shared resources. The RRH determines a first resource grant based at least on the first resource indication indicating at least one of: at least a first resource from the plurality of dedicated resources to allocate to a first baseband unit of the plurality of baseband units, and at least a second resource from the plurality of shared resources to allocate to the first baseband unit. The RRH transmits the first resource grant to the first baseband unit.
