Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple L1 execution instances are used to increase processing capacity, then productivity is improved, but device complexity increases
Solution Approach 1:
The system dynamically enables or disables L1 execution instances based on traffic load conditions. The controller monitors traffic load and activates additional instances when load increases, while disabling instances when load decreases, making the system adaptable to varying demands rather than statically configured
Solution Approach 2:
Multiple L1 execution instances share the same functional capabilities and can handle different parts of radio resource units. Each instance is capable of performing the same L1 processing functions, allowing flexible allocation of work across instances based on current system needs
2Speed
If more L1 execution instances are activated to meet latency requirements, then speed is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts the number of active L1 execution instances based on real-time traffic load and latency requirements. When latency requirements are stringent or traffic load is high, more instances are activated to provide parallel processing capacity. When requirements are relaxed, instances are deactivated to conserve power
Solution Approach 2:
The controller changes the operational state parameter of L1 execution instances from active to inactive based on system conditions. This parameter change allows the system to transition between different power consumption levels while maintaining the capability to meet varying latency requirements
3Use of energy by moving object
If L1 execution instances are dynamically enabled/disabled to optimize power consumption, then energy efficiency is improved, but control complexity increases
Solution Approach 1:
The controller implements a feedback mechanism that monitors traffic load conditions and uses this information to make informed decisions about enabling or disabling L1 execution instances. The system continuously observes system state and adjusts instance activation accordingly, creating a closed-loop control system that optimizes power consumption based on actual demand
4Productivity
If multiple L1 execution instances are used to increase processing capacity, then productivity is improved, but signaling over interfaces increases
Solution Approach 1:
The system segments the radio resource unit into non-overlapping parts and assigns different parts to different L1 execution instances for parallel processing. This segmentation allows multiple instances to work simultaneously on different portions of the same resource unit, increasing processing capacity while managing signaling requirements through structured division of work
