Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

UEs with low paging probability experience high power consumption due to receiving unnecessary paging messages, as they monitor POs in each DRX cycle without proper indication.

Innovation Solution

Implementing paging early indications (PEIs) to determine whether to detect paging information in POs, based on indicators and relationships between PEIs and POs, reducing unnecessary monitoring.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the UE monitors PO in each DRX cycle, then the UE can detect paging messages, but the power consumption increases for UEs with low paging probability

Engineering Contradiction:

Improvepaging message detectionVSAvoidUE power consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The network transmits PEI (Paging Early Indication) before the PO (Paging Occasion) to preliminarily indicate whether there is paging information for the UE. Based on this early indication, the UE can decide whether to wake up and monitor the PO, avoiding unnecessary power consumption while ensuring reliable paging detection when needed.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The PEI signal acts as an intermediary between the network and the UE's PO monitoring. It provides intermediate information that helps the UE make informed decisions about whether to proceed with full paging message detection, thus reducing power consumption without compromising reliability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Use of energy by moving object

If the UE does not monitor PO, then the power consumption is reduced, but the UE may miss paging messages

Engineering Contradiction:

ImproveUE power consumptionVSAvoidpaging message detection

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The network transmits PEI before PO to preliminarily indicate whether paging information exists. This preliminary action ensures that the UE only skips PO monitoring when there is genuinely no paging information, preventing missed detections while reducing power consumption.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The PEI mechanism provides feedback from the network to the UE about the presence of paging information. This feedback loop allows the UE to make accurate decisions about PO monitoring, ensuring reliability is maintained while optimizing power consumption.

Inventive Principle:

Principle #23Feedback

3Device complexity

If the PEI is improperly designed or configured, then the implementation complexity is reduced, but the power consumption reduction is not achieved

Engineering Contradiction:

ImprovePEI design complexityVSAvoidUE power consumption

Core Design Contradiction:

Device complexityVSUse of energy by moving object

Solution Approach 1:

The patent explores different parameter configurations for PEI including timing offsets, frequency resources, and indication formats. By optimizing these parameters, the system achieves effective power consumption reduction while maintaining manageable implementation complexity through standardized configurations.

AI summary

Method, device and computer program product for wireless communication are provided. A method includes receiving, by a wireless communication terminal from a wireless communication node, one or more paging early indications, PEIs. The wireless communication node indicates whether to detect paging information in one of paging occasions, POs, according to an indicator in at least one PEI of the PEIs and a paging indication in a PEI among the PEIs, or according to the paging indication in the PEI and a relationship between the PEIs and the POs.
