Solution Overview

Problem

In dual connectivity architectures, terminals face difficulty in determining which measurement gap to use when multiple network nodes configure different measurement gaps, leading to ambiguity and potential inaccuracies in measurement.

Innovation Solution

A method for a terminal to obtain and determine the appropriate measurement gap by comparing the configurations from multiple network nodes, allowing it to select or ignore specific measurement gaps based on granularity, such as per-UE, per-FR, or per-CC, ensuring accurate measurement gap usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple network nodes configure different measurement gaps for a terminal, then measurement coverage and capabilities are improved, but measurement gap selection ambiguity increases

Engineering Contradiction:
Improvemeasurement gap configuration capabilityVSAvoidmeasurement gap selection clarity
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent segments the measurement gap configuration by introducing granularity levels (per-UE, per-FR, per-CC). Each network node configures measurement gaps at specific granularity levels, and the terminal selects based on the most appropriate granularity for its needs. This segmentation resolves the ambiguity by providing a structured hierarchy rather than treating all measurement gap configurations as equivalent.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent changes the parameter of measurement gap configuration by introducing a granularity parameter. Instead of configuring measurement gaps uniformly, the system now configures them with different granularity levels (per-UE, per-FR, per-CC). The terminal uses this granularity parameter to determine which measurement gap configuration to apply, thereby resolving the selection ambiguity while maintaining multiple configuration capabilities.

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If the terminal autonomously determines the measurement gap to use, then measurement accuracy is improved, but signaling overhead between terminal and network node increases

Engineering Contradiction:
Improvemeasurement gap selection accuracyVSAvoidindication information signaling
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent implements self-service by enabling the terminal to autonomously determine which measurement gap configuration to use based on the granularity level and its own measurement requirements. The terminal independently evaluates the configured measurement gaps and selects the most appropriate one without requiring network node confirmation, thereby reducing signaling overhead while maintaining measurement accuracy.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent uses feedback mechanisms where the terminal reports its measurement gap selection to the network node. The network node receives this feedback and can adjust future measurements gap configurations based on the terminal's actual usage patterns and performance requirements. This feedback loop ensures measurement accuracy while optimizing signaling overhead through intelligent adaptation.

Inventive Principle:
Principle #23Feedback

AI summary

A measurement gap processing method, a terminal, and a network node are provided. The method includes: obtaining a measurement gap configured by a first network node for the terminal and a measurement gap configured by a second network node for the terminal, where the measurement gaps configured by the first network node and the second network node for the terminal are different; and determining, based on the measurement gap configured by the first network node for the terminal and the measurement gap configured by the second network node for the terminal, a measurement gap for use by the terminal.
