Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If PDCCH monitoring is continuously performed according to all search space sets, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The search space sets are divided into two distinct groups: a first group for normal operation and a second group for energy saving operation. The UE can selectively monitor PDCCH according to which group is activated, thereby segmenting the monitoring behavior to balance reliability and power consumption based on current operational needs
Solution Approach 2:
The system dynamically switches between the first and second groups of search space sets based on received indication information. This dynamic switching allows the UE to adapt its PDCCH monitoring behavior in real-time, transitioning from comprehensive monitoring (first group) to reduced monitoring (second group) to optimize the trade-off between reliability and power consumption
2Use of energy by moving object
If search space set groups are switched for NES mode configuration, then power saving is improved, but system complexity increases
Solution Approach 1:
The indication information mechanism serves multiple functions: it triggers SSSG switching, configures NES mode transitions, and coordinates PDCCH monitoring adjustments. By using a single unified indication mechanism to accomplish multiple configuration tasks, the system achieves power saving through NES mode while avoiding the complexity of separate independent mechanisms for each function
