Paging DCI Monitoring Timing from Wake-Up Signal Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies face challenges in determining the monitoring occasion for paging downlink control information (DCI), leading to inefficient power consumption and potential delays in receiving DCI.
Innovation Solution
A method for determining the time domain position of the monitoring occasion for paging DCI based on the reception of a wake-up signal, allowing for precise timing and reduced power consumption by setting specific intervals for switching between wake-up and paging DCI reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the user equipment monitors paging DCI at fixed paging occasions without wake-up signal, then the paging DCI can be received reliably, but the power consumption increases due to continuous monitoring
Solution Approach 1:
The network device sends a wake-up signal before the paging DCI to preemptively wake up the user equipment from sleep state, ensuring the UE is ready to receive paging DCI without requiring continuous monitoring, thus reducing power consumption while maintaining reception reliability
Solution Approach 2:
The wake-up signal acts as an intermediary between the network device and the user equipment, serving as a trigger mechanism that coordinates the transition from sleep to active state and enables reliable paging DCI reception only when needed, resolving the contradiction between power saving and reception reliability
2Productivity
If the monitoring occasion time domain position is not determined based on wake-up signal, then the paging mechanism is simple, but the power consumption management efficiency decreases
Solution Approach 1:
The system establishes a feedback mechanism where the user equipment reports its sleep state and wake-up status to the network device, allowing the network to dynamically adjust and optimize the monitoring occasion timing based on actual UE state, improving power management efficiency through coordinated control
Solution Approach 2:
The monitoring occasion time domain position is made dynamic rather than fixed, adapting to the actual wake-up signal reception timing. The UE determines the monitoring occasion based on when it received the wake-up signal, allowing flexible adjustment that optimizes power consumption without requiring complex predetermined configurations
3Adaptability or versatility
If the paging DCI is sent according to fixed paging frame/occasion, then the network configuration is simple, but the responsiveness to user equipment needs decreases
Solution Approach 1:
The network device sends the wake-up signal in advance before the actual paging DCI transmission, allowing the system to adapt the timing dynamically based on UE needs while maintaining a relatively simple configuration structure. The wake-up signal serves as a flexible trigger that can be adjusted without complicating the overall network configuration

AI summary
A method for monitoring paging downlink control information (DCI) is performed by a user equipment. The method includes: receiving a wake-up signal corresponding to the user equipment; determining a time domain position of a monitoring occasion for monitoring paging DCI according to a time domain position for receiving the wake-up signal; and monitoring paging DCI corresponding to the user equipment at the time domain position of the monitoring occasion for monitoring the paging DCI.
