Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the entire cell supports the LP-WUS paging mode, then terminal devices can save energy, but network load pressure increases greatly
Solution Approach 1:
The patent applies local quality by allowing different terminal devices within the same cell to use different paging modes based on their individual characteristics and network conditions. Specifically, terminal devices are classified into different groups (first group using LP-WUS paging mode, second group using traditional paging mode) based on factors such as power consumption requirements and device capabilities, thereby optimizing energy saving for specific devices without overwhelming the network with universal LP-WUS adoption
Solution Approach 2:
The patent implements dynamics by enabling flexible switching between LP-WUS paging mode and traditional paging mode for terminal devices. The network can dynamically adjust which terminal devices use which paging mode based on real-time network load conditions, terminal device power states, and service requirements, allowing the system to adapt optimally between energy saving and network performance
2Productivity
If the LP-WUS paging mode is not supported, then network load is reduced, but terminal device energy saving is compromised
Solution Approach 1:
The patent applies segmentation by dividing terminal devices into distinct groups that can be paged using different methods. Terminal devices are segmented based on their power consumption characteristics, service types, and network conditions, with some devices receiving LP-WUS paging messages for energy saving while others use traditional paging modes, thus balancing network load with individual device energy requirements
3Use of energy by moving object
If all terminal devices perform LP-WUS paging mode, then energy saving is maximized, but spectrum utilization decreases
Solution Approach 1:
The patent applies local quality by enabling LP-WUS paging mode selectively for specific terminal devices rather than universally. Terminal devices with high power saving requirements and suitable conditions use LP-WUS paging mode to maximize energy saving, while other devices use traditional paging modes, thereby achieving energy efficiency for targeted devices without compromising overall spectrum utilization

AI summary
A communication method, apparatus, and system, related to the field of communication technologies. The communication method includes: determining a first condition that a terminal device supporting a low power wake-up signal (LP-WUS) paging mode in a first cell may meet to perform the LP-WUS paging mode; and sending first indication information to the terminal device, where the first indication information indicates the first condition.
