UE Paging Early Indication Switching for Lower 5G Power Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In certain network configurations, user equipment (UE) using Paging Early Indication (PEI) in 5G systems experiences higher power consumption compared to directly monitoring paging messages during paging occasions, primarily due to time distances among synchronization signal blocks (SSBs), PEI occasions, and paging occasions.
Innovation Solution
A method and apparatus for optimizing power consumption by calculating power penalties between monitoring PEI and directly monitoring paging occasions, and adjusting monitoring behavior based on a predefined threshold, involving a UE that receives a configuration for PEI, calculates power consumption, and decides whether to continue or stop monitoring PEI based on the threshold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If UE monitors PEI to save power, then power consumption is reduced, but in certain network configurations power consumption increases
Solution Approach 1:
The patent applies dynamics by making the PEI monitoring behavior adjustable rather than fixed. The UE dynamically decides whether to monitor PEI based on calculated power penalties and predefined thresholds, adapting its behavior to different network configurations and conditions to optimize power consumption while maintaining reliability
Solution Approach 2:
The patent changes the parameter of monitoring behavior based on calculated power penalties. By comparing power consumption metrics and adjusting the monitoring strategy accordingly (monitoring PEI when beneficial, skipping when harmful), the system optimizes the balance between power saving and reliability across different network scenarios
2Use of energy by moving object
If UE monitors paging occasions directly, then power consumption is reduced in certain configurations, but paging early indication functionality is lost
Solution Approach 1:
The patent applies partial action by selectively monitoring PEI only when beneficial based on power penalty calculations. Rather than continuously monitoring PEI or never monitoring it, the UE partially monitors based on network conditions, achieving optimal power consumption while maintaining the capability to receive early paging indications when needed

AI summary
A method for optimizing power consumption is provided. The method is implemented by user equipment (UE) and includes receiving a configuration for Paging Early Indication (PEI), calculating first power consumption of the UE monitoring the PEI and second power consumption of the UE directly monitoring page messages during one or more paging occasions without monitoring the PEI based on the configuration for PEI and a paging rate of the UE and calculating a power penalty between the first power consumption and the second power consumption. The method includes comparing the power penalty to a predefined threshold and performing one of the following: stopping monitoring the PEI and directly monitoring the paging messages during the one or more paging occasions when the power penalty is greater than the predefined threshold, and continuing to monitor the PEI when the power penalty is less than or equal to the predefined threshold.
