Measurement Gap Switching Across BWP Changes to Preserve Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in existing systems is the inflexible configuration of measurement gaps (MG) due to Band Width Part (BWP) switches, leading to system throughput loss as MGs are always configured, even for measurements that do not require them.
Innovation Solution
A method and apparatus that allow terminals to dynamically adjust measurement gaps before and after BWP switches by receiving configuration information to determine appropriate measurement gaps and sharing schemes, enabling rapid adaptation to BWP changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If measurement gap is always configured for certain measurements, then measurement reliability is improved, but system throughput deteriorates due to unnecessary gaps
Solution Approach 1:
The patent applies dynamics by making the measurement gap configuration changeable based on BWP switch status. The network device dynamically configures or deconfigures measurement gaps according to whether BWP switching is detected, transforming the static gap configuration into a dynamic one that adapts to actual measurement needs, thereby resolving the contradiction between maintaining measurement reliability and preserving system throughput.
Solution Approach 2:
The patent changes the parameter of measurement gap configuration state (configured/deconfigured) based on BWP switch detection. When BWP switching is detected and measurements do not require gaps, the measurement gap configuration is changed from configured to deconfigured state, adjusting the system parameter to eliminate unnecessary throughput loss while maintaining measurement capability when needed.
2Reliability
If measurement gap is configured through RRC signaling, then configuration reliability is improved, but configuration flexibility deteriorates compared to BWP switch indication
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple measurement gap configurations through RRC signaling before BWP switching occurs. The network device prepares different gap configurations in advance, and based on BWP switch detection, selects and activates the appropriate configuration. This preliminary preparation maintains the reliability of RRC-based configuration while enabling flexible adaptation to different BWP scenarios.

AI summary
Embodiments of the disclosure provide a measurement gap determining method and apparatus, and a terminal. The method comprises: the terminal receives first configuration information and/or second configuration information sent by a network device, wherein the first configuration information is used for the terminal to determine a first measurement gap used before BWP switch and a second measurement gap used after the BWP switch, and the second configuration information is used for the terminal to determine a first measurement gap sharing scheme used before the BWP switch and a second measurement gap sharing scheme used after the BWP switch.
