CSI-RS Measurement Requirements for Terminal Capability Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network systems deploy the same set of measurement requirements for all terminals, leading to varying measurement performances among terminals and affecting network system performance due to differing CSI-RS measurement designs and behaviors.
Innovation Solution
A measurement method that determines and reports specific measurement requirements based on information related to CSI-RS receiving time, FFT, SSB measurement, and CSI-RS intervals, allowing terminals to optimize their performance and networks to implement targeted scheduling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network deploys the same set of measurement requirements for all terminals, then the network configuration is simple and uniform, but the measurement performance varies among terminals with different capabilities
Solution Approach 1:
The patent applies local quality by defining different measurement requirement sets (first, second, third sets) tailored to specific terminal capabilities. Terminals with different FFT support (1 FFT vs. multiple FFTs) and different measurement configurations are assigned appropriate requirement sets, ensuring each terminal operates at its optimal performance level rather than forcing uniform requirements on all devices.
Solution Approach 2:
The patent changes the measurement requirement parameters based on terminal capabilities. The network configures different measurement requirements (such as measurement delay, accuracy, resource allocation) according to whether the terminal supports 1 FFT or multiple FFTs, and according to the specific CSI-RS measurement configurations. This dynamic parameter adjustment resolves the contradiction between uniform configuration and capability adaptation.
2Use of energy by moving object
If terminals use different design schemes for CSI-RS measurement (e.g., 1 FFT vs. multiple FFTs), then terminals can optimize their cost and power consumption, but measurement performance becomes inconsistent across the network
Solution Approach 1:
The patent introduces dynamic measurement requirements that adapt to terminal capabilities. Instead of static uniform requirements, the system dynamically adjusts measurement parameters (delay, accuracy, resource allocation) based on whether the terminal uses 1 FFT or multiple FFTs. This dynamic approach allows terminals to optimize power consumption according to their hardware while maintaining consistent measurement performance across the network through appropriate requirement configuration.
3Reliability
If the network configures different measurement requirements for different terminals, then measurement performance is optimized for each terminal, but the network configuration complexity increases
Solution Approach 1:
The patent segments measurement requirements into distinct sets (first set, second set, third set) corresponding to different terminal capability categories. This segmentation allows the network to manage complexity by organizing requirements into manageable groups rather than creating unique configurations for each individual terminal. The segmentation approach simplifies network configuration while still providing tailored optimization for different terminal types.
