Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face challenges in efficiently managing baseband resources, leading to high energy consumption and limited flexibility in adapting to varying traffic loads, as existing technologies cannot easily shut down or reallocate resources without affecting user equipment accessibility and coverage.
Innovation Solution
A method and system that allocate baseband resources from one digital unit to another, allowing for the concentration of computational processing and enabling the shutdown of underutilized digital units during low traffic or maintenance, while maintaining coverage and reducing energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If baseband resources are allocated to multiple digital units to maintain coverage and accessibility, then user equipment service level is improved, but energy consumption increases
Solution Approach 1:
The system dynamically allocates baseband resources by establishing a mapping relationship between radio units and digital units, allowing flexible reconfiguration of resource allocation based on traffic load conditions. This enables the system to adapt to varying service demands while optimizing energy consumption.
Solution Approach 2:
The system changes the allocation parameters of baseband resources by adjusting the mapping between radio units and digital units according to traffic load conditions. When traffic load is low, the system can reallocate resources to fewer digital units, reducing energy consumption while maintaining service level through parameter optimization.
2Use of energy by moving object
If digital units are shut down during low traffic to save energy, then energy consumption is reduced, but system reliability deteriorates
Solution Approach 1:
The system performs preliminary actions by establishing a resource allocation mapping relationship before shutdown occurs. When shutting down digital units during low traffic periods, the system uses pre-established mappings to ensure that affected radio units can be quickly reassigned to operational digital units, maintaining service continuity and system reliability.
Solution Approach 2:
The system introduces an intermediary mapping relationship between radio units and digital units that acts as a mediator during shutdown transitions. This mapping mechanism ensures smooth resource reallocation and maintains service level even when digital units are taken offline for maintenance or energy saving.
3Productivity
If baseband processing is centralized to reduce hardware utilization, then operational expenses are reduced, but adaptability to traffic load changes deteriorates
Solution Approach 1:
The system implements dynamic resource allocation where the mapping between radio units and digital units can be reconfigured based on traffic load conditions. This allows centralized baseband processing to adapt to varying traffic demands, maintaining high hardware utilization efficiency while preserving system adaptability through flexible resource management.
