Solution Overview

Problem

Existing methods for wireless devices in multi-connectivity environments often result in failed or incorrectly configured measurements, leading to wasted energy, processing resources, and radio resources, particularly due to a lack of coordination between network nodes regarding measurement gaps.

Innovation Solution

A method where network nodes coordinate the configuration of measurement gaps for wireless devices, determining whether to configure second measurements based on the status of the first carrier and the device's existing configuration, ensuring coordinated and optimized configuration to avoid redundant measurements and resource wastage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If network nodes independently configure measurement gaps without coordination, then each node can ensure its measurement requirements are met, but resource utilization deteriorates and redundant measurements occur

Engineering Contradiction:

Improvemeasurement configuration reliabilityVSAvoidenergy waste from redundant measurements

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent merges the measurement gap configuration processes of multiple network nodes by introducing a coordinating node that consolidates measurement requirements from different nodes. This coordination mechanism combines previously independent configuration processes into a unified approach, eliminating redundant measurement gaps while ensuring all measurement needs are satisfied through shared resource allocation.

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If network nodes independently configure measurement gaps without coordination, then each node can ensure its measurement requirements are met, but device complexity increases due to handling multiple configurations

Engineering Contradiction:

Improvemeasurement configuration reliabilityVSAvoidconfiguration management complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a coordinating network node as an intermediary that manages measurement gap configurations between multiple network nodes and the wireless device. This intermediary consolidates measurement requirements, determines optimal gap configurations, and distributes unified configuration parameters to the device, thereby reducing the complexity the device would otherwise face in managing multiple independent configurations from different nodes.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If measurement gaps are configured without coordination, then individual node measurement needs can be satisfied, but processing resources are wasted

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent merges overlapping measurement requirements from multiple network nodes into a unified measurement gap configuration. The coordinating node analyzes measurement needs from different nodes, identifies redundant gaps, and creates an optimized set of measurement gaps that satisfies all measurement requirements while minimizing the total number of gaps configured, thereby reducing processing resource consumption in the wireless device.

Inventive Principle:

Principle #5Merging (Combining)

4Reliability

If multiple measurement configurations are provided without coordination, then comprehensive measurement coverage is achieved, but radio resources are wasted

Engineering Contradiction:

Improvemeasurement coverageVSAvoidradio resource waste

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent merges redundant measurement gap configurations by introducing a coordinating node that consolidates measurement requirements from multiple network nodes. This coordination process combines previously independent gap allocations into an optimized unified configuration that maintains comprehensive measurement coverage across all required frequencies and cells while eliminating overlapping and redundant measurement gaps, thereby conserving radio resources.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

Method, performed by a second network node (112), for handling a second configuration for second measurements to be performed by a wireless device (130). The second network node (112) determines (503) whether to configure the wireless device (130) with the second configuration. The second configuration is to configure the wireless device (130) with second measurement gaps to perform second measurements on a first or a second carrier. The determining (503) is based on at least one of: i) a first status of the first carrier, and ii) whether or not the wireless device (130) is configured with a first configuration by a first network node (111). The first configuration is to configure the wireless device (130) with first measurement gaps to perform first measurements on the first carrier. The second network node (112) also initiates (504) providing a first indication based on a first result of the determination.
