Solution Overview
Problem

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the terminal enters a deep sleep mode to save energy, then energy consumption is reduced, but the wake-up duration increases which may not meet service requirements
Solution Approach 1:
The patent applies dynamics by making the sleep mode adjustable rather than fixed. The terminal can dynamically switch between different sleep modes (first sleep mode with longer wake-up duration and second sleep mode with shorter wake-up duration) based on service requirements. This dynamic adjustment resolves the contradiction by allowing the system to optimize between energy saving and wake-up speed depending on the specific service context.
Solution Approach 2:
The patent changes the parameter of wake-up duration by introducing multiple sleep modes with different wake-up characteristics. By receiving indication information from the network device, the terminal adjusts which sleep mode to enter, thereby changing the wake-up duration parameter to match service requirements while maintaining energy efficiency.
2Ease of operation
If the terminal uses a single sleep mode, then the system is simple to operate, but it cannot adapt to different service requirements with varying latency tolerances
Solution Approach 1:
The patent segments the single sleep mode into multiple distinct sleep modes (first sleep mode and second sleep mode), each with different wake-up duration characteristics. This segmentation allows the system to provide different levels of service adaptation while maintaining operational simplicity through network-controlled selection.
Solution Approach 2:
The patent implements multi-functionality by making the sleep mode system serve multiple service requirements. The same sleep mode mechanism can adapt to both latency-sensitive services (using second sleep mode) and latency-insensitive services (using first sleep mode), making the system universally applicable to different service types without requiring separate mechanisms.
3Reliability
If the terminal monitors PDCCH continuously to ensure data transmission meets service requirements, then service reliability is improved, but energy consumption increases
Solution Approach 1:
The patent applies periodic action through DRX (Discontinuous Reception) cycles, where the terminal alternates between active monitoring periods and sleep periods. By selecting appropriate sleep modes within these periodic cycles based on service requirements, the system maintains data transmission reliability during active periods while reducing energy consumption during sleep periods.
Solution Approach 2:
The patent makes the monitoring behavior dynamic by allowing the terminal to adjust its sleep mode selection based on service requirements and network indications. This dynamic adjustment optimizes the balance between monitoring intensity (for reliability) and energy saving, avoiding continuous monitoring while ensuring service requirements are met.
Data Source
AI summary
This application provides a communication method, apparatus, and system, and belongs to the field of communication technologies. In the method, a network device may send first indication information to a terminal based on service requirements of different services, to indicate the terminal to enter a first sleep mode whose wake-up duration matches a service requirement of the terminal, so that even if the terminal is woken up in the first sleep mode, subsequent data transmission of the terminal can still meet the service requirement of the terminal.
