Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If dual connectivity scheme is used to receive service through both macro cell and small cell, then service capacity is improved, but device complexity and connection management difficulty increase
Solution Approach 1:
The patent segments the time interval into multiple sub-intervals, with each sub-interval dedicated to receiving service from a specific base station (macro cell or small cell). This time-based segmentation simplifies the dual connectivity management by creating distinct reception periods for each cell type, avoiding the complexity of simultaneous multi-cell management.
Solution Approach 2:
The patent implements dynamic switching between macro cell and small cell reception based on varying service requirements and channel conditions. The receiver adapts its operation by selecting different base stations for different time sub-intervals, enabling flexible resource allocation while maintaining manageable system complexity.
2Reliability
If seamless switching operation between macro cell and small cell is implemented, then service quality is improved, but switching complexity and timing synchronization difficulty increase
Solution Approach 1:
The patent performs preliminary configuration of timing relationships between macro cell and small cell before actual service reception. By pre-establishing the timing synchronization and switching points, the system ensures seamless transitions while reducing the complexity of real-time switching operations.
Solution Approach 2:
The patent employs periodic switching between macro cell and small cell reception at predetermined time intervals. This periodic structure simplifies the switching operation by creating regular, predictable transition points that are easier to manage and synchronize compared to arbitrary switching.
3Productivity
If time division multiplexing is used for dual connectivity, then load distribution efficiency is improved, but time interval management complexity increases
Solution Approach 1:
The patent changes the time interval parameters dynamically based on service requirements and base station conditions. By adjusting the duration and timing of sub-intervals allocated to each cell type, the system optimizes load distribution while managing time interval complexity through adaptive parameter adjustment.
