Solution Overview

Problem

Concurrent measurement gap patterns in wireless communication systems can lead to delays or loss of feedback signals, degrading serving cell performance due to overlapping measurement gaps, which affects data throughput and reliability.

Innovation Solution

Implementing a method in wireless devices and network nodes to cancel or discard measurement gaps based on predefined rules when they occur close in time, allowing for adaptive measurement procedures such as restarting, discarding, or switching to alternative measurement gap patterns, ensuring continuous and reliable measurements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If concurrent measurement gap patterns are used to perform measurements on multiple carriers, then measurement coverage is improved, but overlapping measurement gaps cause delays or loss of feedback signals degrading serving cell performance

Engineering Contradiction:

Improvemeasurement coverageVSAvoidfeedback signal reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent extracts and removes overlapping measurement gaps from the concurrent measurement gap patterns. When overlap is detected between measurement gaps of different patterns, the overlapping gaps are cancelled or removed, preventing the harmful effect of overlapping on feedback signal transmission while preserving the non-overlapping measurement gaps that provide measurement coverage.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent implements dynamic adjustment of measurement gap patterns by continuously monitoring for overlaps and adaptively cancelling overlapping gaps in real-time. This dynamic approach allows the system to maintain optimal measurement coverage when gaps do not overlap while automatically preventing feedback signal degradation when overlaps occur.

Inventive Principle:

Principle #15Dynamics

2Reliability

If measurement gaps are cancelled to prevent feedback signal loss, then feedback signal reliability is improved, but measurement procedures may be interrupted affecting measurement continuity

Engineering Contradiction:

Improvefeedback signal reliabilityVSAvoidmeasurement continuity

Core Design Contradiction:

ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent applies preliminary action by detecting and cancelling overlapping measurement gaps before they can cause feedback signal loss. The system proactively identifies potential overlaps between concurrent measurement gap patterns and removes the overlapping gaps in advance, preventing the harmful effect before it occurs rather than reacting after damage is done.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent discards overlapping measurement gaps that would cause conflicts, but recovers measurement continuity by ensuring that the cancellation of overlapping gaps does not create measurement gaps in the serving cell that would interrupt ongoing measurements. The system carefully manages the discarding of problematic gaps while maintaining measurement continuity through proper gap pattern coordination.

Inventive Principle:

Principle #34Discarding and recovering

3Reliability

If adaptive measurement procedures are implemented to handle gap cancellation, then measurement robustness is improved, but device complexity increases

Engineering Contradiction:

Improvemeasurement robustnessVSAvoidmeasurement procedure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements self-service by enabling the wireless device to autonomously detect overlapping measurement gaps and perform self-cancellation without requiring complex network coordination or external control. The device independently monitors its own measurement gap patterns, identifies overlaps, and cancels problematic gaps, reducing the need for complex external control mechanisms.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent applies preliminary action by pre-configuring multiple measurement gap patterns with different characteristics (e.g., different periodicities, offsets, or durations). These pre-configured patterns are designed to provide redundancy and alternatives, allowing the device to switch between patterns or cancel overlapping ones without requiring complex real-time decision-making algorithms.

Inventive Principle:

Principle #10Preliminary action

AI summary

A network node and method for measurement rules under concurrent measurement gap cancellation are disclosed. A configuration is received, where the configuration indicates a first measurement gap pattern having a first plurality of measurement gaps and a second measurement gap pattern having a second plurality of measurement gaps. A first reference signal is measured according to the first measurement gap pattern and a second reference signal is measured according to the second measurement gap pattern. A number N of the first plurality of measurement gaps for performing measurements is cancelled based on an overlap of at least one of the first plurality of measurement gaps with at least one of the second plurality of measurement gaps. At least one action is performed based on N being greater than a first threshold value.
