Dynamic Function Division Between REC and RE for Baseband Resource Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is challenging to achieve a balance between the coordination feature and interface bandwidth in distributed base station systems, where reducing interface bandwidth between the Radio Equipment Controller (REC) and Radio Equipment (RE) increases costs and processing pressure, and existing function division solutions either compromise coordination or require fixed function allocations.
Innovation Solution
A service execution method where the RE sends a baseband resource status to the REC, which generates a baseband configuration and division solution, allowing both components to dynamically adjust their functions based on current application scenarios, thereby reducing interface bandwidth while maintaining coordination features through shared baseband processing resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If function division is performed at a fixed position between REC and RE, then interface bandwidth is reduced, but coordination feature is compromised
Solution Approach 1:
The patent implements dynamic function division where the dividing line between REC and RE functions is not fixed but can be adjusted based on coordination requirements. The system dynamically determines which baseband functions (L1, L2, L3) are performed by REC versus RE, allowing the interface bandwidth to be reduced while maintaining necessary coordination capabilities through flexible function allocation rather than static division.
Solution Approach 2:
The system changes the parameter of function division position dynamically. Instead of a fixed division point, the patent allows the division position to vary based on traffic conditions, coordination needs, and resource availability. This enables optimization of interface bandwidth while preserving coordination features by adjusting which protocol layers are processed at each node.
2Quantity of substance
If more baseband functions are moved to RE, then interface bandwidth between REC and RE is reduced, but device complexity increases
Solution Approach 1:
The patent segments baseband processing functions into different layers (L1, L2, L3) and allows flexible assignment of these segments between REC and RE. Rather than moving all functions to RE, the system selectively divides functions at appropriate layers, reducing interface bandwidth while managing device complexity through structured segmentation of processing tasks.
Solution Approach 2:
The REC is designed with multi-functionality to handle both control functions and variable baseband processing functions depending on the division configuration. This universality allows the system to reduce interface bandwidth by moving functions to RE when beneficial, while the REC can compensate by performing additional baseband processing when coordination requirements demand, thus managing overall device complexity.
3Ease of manufacture
If fixed function division is implemented, then implementation is simple, but adaptability to different scenarios is poor
Solution Approach 1:
The patent transforms the static function division into a dynamic system that can adapt to different scenarios. The dividing line between REC and RE functions is determined dynamically based on traffic conditions, coordination requirements, and resource status, enabling the system to adapt to varying scenarios while maintaining implementation feasibility through standardized dynamic adjustment mechanisms.
Solution Approach 2:
The system changes the division parameters (which protocol layers are processed where) based on different application scenarios. Instead of a fixed implementation, the patent allows the division configuration to be adjusted according to traffic patterns, coordination needs, and resource availability, thereby achieving both adaptability and reasonable implementation complexity through parameter-based flexibility.
