Measurement Gap Configuration for 5G BWP Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of radio resource management (RRM) increases with the use of bandwidth parts (BWP) in 5G New Radio (NR) technology, particularly due to the need for dynamic measurement gap configuration during BWP switching.
Innovation Solution
A user equipment (UE) determines a third measurement gap configuration for both the initial and active BWPs, based on preconfigured measurement gap configurations for each BWP. This third configuration includes a reporting period for generating a report result about the carrier, allowing consistent measurements after BWP switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If dynamic measurement gap configuration is implemented for each BWP, then measurement accuracy is improved, but RRM complexity increases
Solution Approach 1:
The patent applies universality by introducing a common measurement gap configuration that can be applied across multiple BWPs. Instead of maintaining separate measurement gap configurations for each BWP, the system uses a unified configuration that serves all BWPs, thereby reducing RRM complexity while maintaining measurement accuracy through the common configuration framework.
Solution Approach 2:
The patent merges the measurement gap configurations by combining multiple BWP-specific configurations into a single common measurement gap configuration. This consolidation reduces the number of configuration parameters that need to be managed and processed, directly addressing the RRM complexity issue while preserving the necessary measurement capabilities across different BWPs.
2Stability of the object's composition
If separate measurement gap configurations are maintained for each BWP, then measurement consistency within each BWP is improved, but switching overhead between BWPs increases
Solution Approach 1:
By using a common measurement gap configuration that applies to multiple BWPs, the patent eliminates the need to switch between different configurations when changing BWPs. This universal approach maintains measurement consistency through the common configuration framework while reducing switching overhead, as no configuration reconfiguration is needed during BWP transitions.
3Productivity
If measurement gap configuration is optimized for individual BWPs, then resource efficiency is improved, but configuration complexity increases
Solution Approach 1:
The patent merges individual BWP-specific measurement gap optimizations into a single common configuration that serves all BWPs. This approach maintains resource efficiency by applying optimized measurement gap parameters across all BWPs, while simultaneously reducing configuration complexity by eliminating the need to manage multiple separate configurations.

AI summary
Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for generating a report result based on a set of measurements performed at measurement gaps during a reporting period. The set of measurements are performed on a reference signal at a first bandwidth part (BWP) or a second BWP when BWP switching is performed. The first BWP has a first measurement gap configuration, the second BWP has a second measurement gap configuration. The measurement gaps of the reporting period are configured according to a third measurement gap configuration that is determined based on the first measurement gap configuration and the second measurement gap configuration.
