UE Beam Measurement Configuration for Low-Latency Mobility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in beam measurement, particularly in high-speed mobile scenarios like high-speed rail or highways, where high-level RRM measurements lead to latency issues and potential service interruptions due to the averaging of physical layer measurements, which are not suitable for all scenarios.
Innovation Solution
A measurement configuration method that allows User Equipment (UE) to obtain and process configuration information indicating different measurement behaviors, such as Layer 1 and Layer 3 measurements, to adapt beam measurement strategies based on specific scenarios, reducing latency and ensuring continuous service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high-level RRM measurement is used for non-serving cell measurement, then measurement accuracy is improved through filtering, but measurement latency increases and service interruption occurs in high-speed scenarios
Solution Approach 1:
The patent applies dynamics by making the measurement behavior configurable and adaptable to different scenarios. The network device dynamically selects between Layer 1 and Layer 3 measurement behaviors based on UE mobility conditions, transforming the static measurement process into a dynamic one that responds to changing channel conditions and mobility states
Solution Approach 2:
The patent changes the measurement behavior parameter from a fixed high-level RRM measurement to a configurable selection between Layer 1 and Layer 3 measurements. This parameter change allows the system to switch measurement filtering levels based on scenario requirements, resolving the contradiction between accuracy and latency
2Stability of the object's composition
If Layer 3 measurement filtering is applied to obtain stable measurement results, then measurement stability is improved, but measurement responsiveness deteriorates in high-speed mobile scenarios
Solution Approach 1:
The patent makes the measurement stability-responsiveness tradeoff dynamic by allowing the network device to select between Layer 1 (fast, less stable) and Layer 3 (stable, slow) measurement behaviors based on real-time mobility conditions, enabling the system to adapt to changing speed requirements
Solution Approach 2:
The patent changes the measurement filtering parameter from always applying Layer 3 filtering to selectively applying Layer 1 or Layer 3 filtering based on the configured measurement behavior, allowing the system to adjust stability versus responsiveness characteristics
3Measurement precision
If analog beamforming training is performed with sequential transmission of training signals, then beam measurement accuracy is improved, but measurement time increases
Solution Approach 1:
The patent applies partial action by allowing the UE to perform only the necessary measurement depth based on the configured behavior. With Layer 1 measurement, the UE performs physical layer measurement without extensive Layer 3 filtering, achieving sufficient accuracy with reduced measurement time compared to full Layer 3 processing
