Engineering Contradiction Analysis
1Ease of operation
If conventional mobile communication networks allow data transmission on demand without active control architecture, then user equipment can freely transmit data whenever needed, but network load management and energy efficiency deteriorate
Solution Approach 1:
The network performs preliminary actions by pre-configuring control parameters and transmission opportunities before actual data transmission occurs. The base station evaluates network conditions in advance and pre-determines optimal transmission timing, allowing user equipment to transmit data efficiently without causing unnecessary network load or energy consumption.
Solution Approach 2:
The system dynamically adjusts transmission parameters based on real-time network conditions. The base station continuously monitors network load, available resources, and energy constraints, then dynamically modifies transmission opportunities and control parameters to balance user equipment operational flexibility with network energy efficiency.
2Device complexity
If no active control architecture is implemented, then network complexity remains low, but ability to manage data transmission based on load and capacity considerations deteriorates
Solution Approach 1:
The control architecture is segmented into modular components: the base station handles high-level network condition evaluation and control parameter determination, while individual user equipment handles execution of transmission within allocated opportunities. This segmentation allows scalable deployment without proportionally increasing overall system complexity.
Solution Approach 2:
The system implements feedback mechanisms where the base station monitors network load, transmission success rates, and resource utilization, then uses this information to adjust control parameters and transmission opportunities. This feedback loop enables effective network load management without requiring overly complex centralized control.
3Speed
If data transmission is not scheduled based on network conditions, then transmission speed remains high when possible, but overall network efficiency and energy consumption deteriorate
Solution Approach 1:
The base station periodically evaluates network conditions and schedules transmission opportunities in periodic cycles. During periods of high network load or energy constraints, transmission opportunities are reduced or delayed. During periods of low load, transmission speed is maximized. This periodic scheduling balances transmission speed with overall network efficiency.
Solution Approach 2:
The system changes key parameters such as transmission timing, data rate, and resource allocation based on network conditions. The base station adjusts these parameters dynamically to optimize both transmission speed and network efficiency, scheduling high-speed transmissions during optimal windows while maintaining overall system productivity.
