Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multi-connectivity scheduling is implemented across different cell groups, then spectral efficiency and network performance are improved, but system complexity and scheduling management difficulty increase
Solution Approach 1:
The system divides cell groups into different scheduling domains, with each cell group managed by independent scheduling entities. This segmentation allows parallel scheduling operations across cell groups while maintaining manageable complexity within each group, resolving the contradiction between improved spectral efficiency and increased system complexity.
Solution Approach 2:
A centralized scheduling manager acts as an intermediary between multiple cell group schedulers, coordinating scheduling decisions and resource allocation across cell groups. This mediator enables efficient cross-cell-group scheduling while abstracting the complexity from individual scheduling entities.
2Reliability
If scheduling information is exchanged between cells in different cell groups, then coverage and latency are improved, but control channel overhead and signaling complexity increase
Solution Approach 1:
The patent combines scheduling information for multiple cell groups into unified control channel transmissions where possible, and merges related signaling messages to reduce redundant overhead. This consolidation maintains necessary coverage information while minimizing control channel resource consumption.
Solution Approach 2:
Critical scheduling information is extracted and transmitted through dedicated control channels, while less critical information is handled through data channel signaling or pre-configured parameters. This extraction strategy ensures coverage reliability for essential information while reducing overall control channel overhead.
