Script Reuse for Inter-Frequency UE Measurements

Solution Overview

Problem

In wireless communications, user equipment (UE) currently regenerates scripts for inter-frequency or inter-radio access technology (IRAT) measurements and paging activities each time, leading to inefficient use of time and processor resources.

Innovation Solution

The UE reuses saved scripts for inter-frequency or IRAT measurements and paging by comparing configurations of source and target cells, allowing for power-efficient operations and reducing the need for script regeneration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the UE regenerates a script each time for inter-frequency or IRAT measurement or paging activity, then the UE can ensure the script is up-to-date with current configurations, but the UE consumes excessive processor resources and time

Engineering Contradiction:

Improvescript accuracyVSAvoidprocessor efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The UE performs preliminary actions by saving scripts during previous measurement or paging activities and retaining them for potential reuse. The UE compares current configurations with saved script configurations to determine reusability, avoiding the need to regenerate scripts from scratch each time.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The UE monitors changes in configuration parameters (frequency, bandwidth, RAT type) and uses this information to determine whether a saved script can be reused. When parameters remain within acceptable ranges, the UE reuses the saved script; when parameters change significantly, the UE regenerates the script.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If the UE regenerates a script each time for inter-frequency or IRAT measurement or paging activity, then the UE ensures compatibility with current network conditions, but the UE wastes time and processor resources

Engineering Contradiction:

Improveconfiguration compatibilityVSAvoidscript generation time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The UE performs preliminary actions by saving scripts during previous measurement or paging activities and retaining them for potential reuse. The UE compares current configurations with saved script configurations to determine reusability, avoiding the need to regenerate scripts from scratch each time.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The UE creates copies of previously successful scripts and reuses them when current conditions match the saved script's configuration parameters. This copying approach allows the UE to maintain adaptability while avoiding redundant script generation.

Inventive Principle:

Principle #26Copying

3Use of energy by moving object

If the UE saves and reuses scripts for measurement or paging activities, then the UE saves power and processor resources, but the UE may lack memory to run pre-generated scripts in some cases

Engineering Contradiction:

Improvepower consumptionVSAvoidmemory management complexity

Core Design Contradiction:

Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The UE monitors changes in configuration parameters (frequency, bandwidth, RAT type) and uses this information to determine whether a saved script can be reused. When parameters remain within acceptable ranges, the UE reuses the saved script; when parameters change significantly, the UE regenerates the script.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The UE performs self-service by automatically comparing current configurations with saved script configurations and independently deciding whether to reuse or regenerate scripts. This self-service mechanism simplifies memory management by having the UE make intelligent decisions about script usage without external intervention.

Inventive Principle:

Principle #25Self-service

AI summary

Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) may be scheduled to perform a first measurement or paging activity associated with a target cell operating according to a first target cell configuration that is different from a serving cell operating according to a first serving cell configuration of the UE. In some cases, the UE may determine that the UE has performed a previous measurement or paging activity associated with the target cell while being served by the serving cell, the cells operating according to previous cell configurations. The UE may compare at least one of the first and previous target cell configurations or the first and previous serving cell configurations, and may perform the first measurement or paging activity using a script, where the script is either reused or rebuilt based on comparing the cell configurations.
