Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If time windows are defined for data radio bearers to improve resource scheduling flexibility, then system flexibility and resource utilization efficiency are improved, but device complexity and signaling overhead increase
Solution Approach 1:
The patent divides the communication resource allocation into multiple time windows (first time window and second time window) with different characteristics. The first time window is used for initial access and random access procedures, while the second time window is used for data transmission. This segmentation allows the system to optimize resource allocation for different purposes without requiring complete reconfiguration of the entire system, thereby improving flexibility while managing complexity.
Solution Approach 2:
The patent introduces dynamic time window configurations where the start time, end time, and duration of time windows can be adjusted based on traffic conditions and system state. The network can dynamically indicate time window parameters through signaling, allowing the system to adapt to changing requirements in real-time while maintaining a structured framework that prevents unbounded complexity.
2Productivity
If time windows are defined for data radio bearers to improve resource scheduling flexibility, then resource utilization efficiency is improved, but signaling overhead increases
Solution Approach 1:
The patent combines multiple configuration parameters into unified time window definitions. Instead of separately signaling start time, end time, duration, and other parameters for each resource allocation, the system defines time windows as composite entities that encompass multiple parameters. This merging reduces the total number of signaling messages and parameters that need to be transmitted, thereby reducing signaling overhead while maintaining comprehensive resource control.
Solution Approach 2:
The patent establishes time window configurations in advance through pre-defined patterns and templates. The network can configure time window parameters beforehand and reuse these configurations for multiple resource allocations, reducing the need for repeated detailed signaling. Pre-configured time windows provide a framework that guides subsequent resource allocation decisions without requiring extensive real-time signaling.
3Productivity
If time characteristics are considered in session management to improve resource allocation efficiency, then resource utilization efficiency is improved, but device complexity increases
Solution Approach 1:
The patent applies different time window characteristics to different data radio bearers and traffic types based on their specific requirements. Instead of using a uniform time management approach for all bearers, the system configures appropriate time windows (first time window for access, second time window for data) according to the local needs of each bearer. This localized approach improves resource allocation efficiency for each specific traffic type while avoiding the complexity of a completely customized solution for every bearer.
