BWP Measurement Gap Configuration for Higher RRM Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio resource management (RRM) systems waste resources and reduce system throughput due to the need for measurement gaps across all bands, which prevents uplink and downlink transmission during measurements.
Innovation Solution
Configure measurement gaps based on bandwidth parts (BWPs) rather than overall bands, allowing gaps only where necessary, reducing the number of configured gaps and optimizing resource use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If measurement gaps are configured on all bands, then measurement coverage is improved, but resource wastage increases and system throughput decreases
Solution Approach 1:
The patent segments the measurement gap configuration by bandwidth part (BWP), allowing different measurement gap settings for different BWPs rather than applying a uniform configuration across all bands. This enables selective application of measurement gaps only where necessary, resolving the contradiction between comprehensive measurement coverage and system throughput efficiency.
Solution Approach 2:
The patent implements local quality by configuring measurement gaps based on specific BWP requirements. Each BWP can have its own measurement gap configuration indicator, allowing the system to apply measurement gaps locally only to BWPs that require them, rather than universally across all bands. This maintains measurement reliability where needed while preserving throughput in bands that don't require measurement gaps.
2Reliability
If measurement gaps are configured on all bands, then measurement completeness is improved, but resource usage efficiency deteriorates
Solution Approach 1:
The patent applies partial action by configuring measurement gaps only for specific BWPs that require them, rather than applying measurement gaps excessively across all bands. The network device determines, based on indication information, which BWPs need measurement gaps and configures them accordingly, achieving measurement completeness for necessary bands while avoiding resource wastage in bands that don't require measurement gaps.
3Measurement precision
If measurement gaps are configured for all bandwidth parts, then measurement accuracy is improved, but device complexity increases
Solution Approach 1:
The patent introduces dynamics by making the measurement gap configuration adaptive to each BWP's requirements. The network device dynamically determines which BWPs need measurement gaps based on indication information, and the terminal adapts its measurement behavior accordingly. This dynamic approach maintains measurement accuracy for BWPs that require it while reducing configuration complexity compared to static universal measurement gap configuration.
