Solution Overview

Problem

In 5G wireless systems, the overlap between measurement gaps and synchronization-signal block (SSB) measurement timing configurations (SMTC) can lead to collisions and performance issues, affecting user equipment (UE) measurements and data transmission.

Innovation Solution

The network configures user equipment (UE) to perform measurements in a way that avoids or manages overlaps between measurement gaps and SMTC/RLM configurations, using techniques such as gap sharing mechanisms and configuration tables to optimize measurement types and timing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If measurement gaps are configured for UE measurements, then measurement capability is improved, but collision with SSB timing causes performance degradation

Engineering Contradiction:
Improvemeasurement capabilityVSAvoidperformance loss
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The network performs preliminary configuration of measurement timing configurations (MTC) that specify when SSB measurements should occur. By pre-configuring these timing parameters before actual measurements, the system ensures that measurement activities are scheduled in advance, allowing the UE to prepare and avoid conflicts with measurement gaps, thereby preventing performance degradation while maintaining measurement capability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts measurement timing configurations based on current network conditions and UE capabilities. The MTC parameters can be modified and reconfigured to optimize the timing of SSB measurements relative to measurement gaps, allowing the system to adaptively resolve collisions and maintain reliable measurements without fixed rigid timing constraints.

Inventive Principle:

2Measurement precision

If measurement timing configuration is optimized for SSB measurements, then measurement precision is improved, but complexity of configuration management increases

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The measurement timing configuration (MTC) framework serves multiple functions simultaneously: it defines SSB measurement timing, coordinates with measurement gaps, and provides a standardized configuration interface. This multi-functional approach allows a single configuration mechanism to handle both timing precision requirements and coordination complexity, reducing overall system complexity while maintaining measurement accuracy.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If measurement gaps are extended to ensure complete measurements, then measurement reliability is improved, but data transmission interruptions increase

Engineering Contradiction:

Solution Approach 1:

The system changes the timing parameters of measurement configurations to align SSB measurements with available measurement gap opportunities. By adjusting the timingOffset and other MTC parameters, the system ensures that measurements are completed within shorter gap durations, maintaining measurement reliability while reducing the length of interruptions to data transmission, thereby preserving productivity.
