Paging and Reference Signal Timing Alignment for Lower Terminal Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies fail to effectively reduce power consumption in terminal devices operating in RRC_IDLE or RRC_INACTIVE states by optimizing the reception times of paging and reference signals.
Innovation Solution
A terminal device adjusts the reception times of paging and reference signals by requesting configuration information changes, allowing for flexible alignment and reducing energy consumption through optimized signal reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the terminal device receives paging signal and reference signal at separate configured times, then the device can maintain proper signal reception schedules, but energy consumption increases due to multiple wake-up events
Solution Approach 1:
The patent merges the reception timing of paging signals and reference signals by allowing the terminal to indicate a first time for paging signal reception and receive the reference signal at the same first time instead of a separate second time. This combines two separate reception events into one, reducing the number of wake-up events and thereby reducing energy consumption while maintaining reliable signal reception.
Solution Approach 2:
The patent introduces dynamic timing adjustment mechanisms where the terminal can indicate its preferred reception time for paging signals, and the network can adjust the reference signal timing based on terminal feedback. This dynamic adjustment allows the system to optimize reception timing according to actual conditions, enabling energy-saving opportunities without compromising reception reliability.
2Adaptability or versatility
If the terminal device uses fixed DRX cycle timing for signal reception, then the reception schedule is simple and stable, but flexibility in optimizing energy consumption is limited
Solution Approach 1:
The patent enables preliminary timing indication where the terminal can indicate its preferred reception time before the actual signal transmission. This allows the network to pre-configure or adjust timing in advance, providing flexibility in optimizing energy consumption patterns without requiring complex real-time adjustments during operation.
Solution Approach 2:
The patent implements feedback mechanisms where the terminal provides timing preference information to the network, and the network responds by adjusting reference signal timing configurations. This feedback loop enables adaptive optimization of reception timing, increasing flexibility while managing complexity through standardized feedback procedures.

AI summary
A communication method and a communication apparatus. A terminal device may request a network device to reconfigure current configuration information of a paging signal or current configuration information of a reference signal, so that an interval between a receiving time of the paging signal and a receiving time of the reference signal is adjusted based on an actual service requirement. This can not only reduce energy consumption of the terminal device, but also implement flexible configuration of the paging signal and the reference signal of the terminal device.
