Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If wideband frequencies are secured to provide high data rate services, then transmission speed is improved, but frequency availability becomes limited and data service fees increase
Solution Approach 1:
The base station system enables mobile systems to access both licensed spectrum and shared spectrum, allowing the same communication infrastructure to serve multiple spectrum types. The system classifies mobile systems based on their capability to use shared spectrum and dynamically allocates appropriate spectrum resources, making the network universally compatible with different spectrum types and access capabilities.
Solution Approach 2:
The system dynamically classifies mobile systems into different types based on their shared spectrum access capability and continuously allocates spectrum resources according to current network conditions and mobile system requirements. This dynamic classification and allocation allows the system to adapt to changing traffic demands and spectrum availability in real-time.
2Reliability
If mobile systems continuously monitor control messages to maintain service connectivity, then service reliability is improved, but power consumption increases
Solution Approach 1:
The base station system sends control messages periodically to mobile systems in a predictable pattern. Mobile systems can enter sleep mode between periodic control message transmissions and wake up to monitor for new messages, reducing continuous power consumption while maintaining the ability to receive service notifications and maintain connectivity when needed.
3Productivity
If shared spectrum is dynamically allocated to mobile systems, then spectrum utilization efficiency is improved, but system complexity increases
Solution Approach 1:
The base station system segments mobile systems into different classification groups based on their shared spectrum access capability. This segmentation allows the system to apply different spectrum allocation strategies to different groups, simplifying the overall management complexity while still achieving efficient spectrum utilization through targeted dynamic allocation to capable devices.
