Dynamic Measurement Gap Configuration for 5G BWP Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Fifth Generation (5G) New Radio (NR) networks, the configuration of measurement gaps (MGs) during bandwidth part (BWP) switching disrupts intra-frequency measurements, affecting radio resource management (RRM) efficiency for both User Equipment (UE) and the network, leading to throughput degradation.
Innovation Solution
Implementing a method that allows the UE to dynamically activate or deactivate measurement gaps based on BWP switching events, using signaling information to determine when MGs are necessary, thereby enabling measurements while minimizing unnecessary throughput loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If measurement gaps are configured during BWP switching, then intra-frequency measurements can be performed, but data throughput is degraded due to interruption of communication
Solution Approach 1:
The patent applies dynamics by making the measurement gap configuration adaptive rather than static. The network dynamically configures measurement gaps based on actual BWP switching events, allowing the system to adjust measurement resources according to real-time communication needs, thereby reducing unnecessary throughput loss while maintaining measurement capability
Solution Approach 2:
The patent changes the parameter of measurement gap configuration from a fixed state to a conditional state based on BWP switching. By modifying the configuration parameters according to whether BWP switching occurs, the system optimizes the balance between measurement reliability and data throughput efficiency
2Reliability
If measurement gaps are always configured, then measurement coverage is ensured, but RRM efficiency is reduced due to unnecessary gap configurations during BWP switching
Solution Approach 1:
The patent applies partial action by configuring measurement gaps only when necessary (during BWP switching events that affect measurement continuity) rather than always configuring them. This partial configuration approach ensures sufficient measurement coverage while avoiding the RRM efficiency loss caused by unnecessary gap configurations
Solution Approach 2:
The patent implements feedback mechanisms where the network monitors BWP switching events and uses this information to determine whether measurement gap configuration is necessary. This feedback-driven approach optimizes RRM efficiency by avoiding unnecessary measurements while maintaining adequate coverage
