Delayed Wake-Up Terminal Timing for Adaptive PDCCH Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing mobile communication systems, terminals face challenges in determining the appropriate power-saving mode due to unclear next time points for returning to PDCCH monitoring, leading to inefficient power consumption and service transmission.
Innovation Solution
A method and apparatus for a delayed wake-up terminal that involves obtaining and determining a first time interval based on indication information, allowing the terminal to adaptively enter different power-saving modes by indicating the time interval from wake-up signal monitoring to the ability to monitor other channels or signals, such as PDCCH, thereby optimizing power consumption.

Engineering Contradiction Analysis
1Use of energy by moving object
If the terminal enters a deeper sleep state to save more power, then power consumption is reduced, but the delay to return to PDCCH monitoring state increases
Solution Approach 1:
The patent applies dynamics by making the sleep state configurable and adaptable. The network can dynamically indicate different time intervals (first time interval, second time interval, third time interval) that correspond to different sleep depths, allowing the terminal to adjust its power-saving strategy based on actual service requirements rather than using a fixed sleep pattern.
Solution Approach 2:
The patent changes the parameter of sleep state depth by introducing multiple time interval parameters (first, second, third time intervals) that represent different levels of sleep depth. The network indicates which time interval to use, thereby controlling the terminal's power consumption and wake-up delay characteristics without changing the hardware or fundamental system architecture.
2Speed
If the terminal enters a lighter sleep state to reduce wake-up delay, then responsiveness is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts the sleep state based on network indications. When fast response is needed, the network can indicate a shorter time interval (second or third time interval), causing the terminal to use a lighter sleep state. When power saving is prioritized, the network can indicate a longer time interval (first time interval), allowing deeper sleep.
Solution Approach 2:
The patent uses parameter changes to control sleep depth by selecting among multiple time interval values. Each time interval parameter corresponds to a different balance point between wake-up speed and power consumption, allowing flexible optimization based on service requirements.
3Adaptability or versatility
If the terminal does not know the next PDCCH monitoring time point, then flexibility in sleep state selection is lost, but the system complexity is reduced
Solution Approach 1:
The network provides feedback to the terminal by indicating the appropriate time interval (first, second, or third) that the terminal should use for its sleep state. This feedback mechanism allows the terminal to adapt its power-saving behavior to match network expectations and service requirements without the terminal needing to independently determine the optimal sleep state.
Solution Approach 2:
The time interval indication acts as an intermediary that translates network service requirements into terminal power-saving configuration. Rather than the terminal directly deciding its sleep state or the network directly controlling each wake-up event, the time interval indication mediates between these two, providing a simple yet effective control mechanism.

AI summary
An indication method and apparatus for a delayed wake-up terminal and a device are provided. The indication method includes: obtaining, by a terminal, first indication information; and determining, by the terminal, a first time interval based on the first indication information. The first time interval is any one of the following: a time interval allowed from a time when the terminal monitors a wake-up signal to a time when the terminal is able to monitor a first object; or a time interval allowed from a time when the terminal determines to start monitoring the first object to a time when the terminal is able to monitor the first object. The first object is a channel or a signal other than the wake-up signal.
