Radio Resource Management Measurement Configuration for Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio resource management (RRM) measurement methods in E-UTRA systems face challenges in ensuring accuracy, particularly in new carrier type (NCT) cells where reduced cell-specific reference signals (RCRS) are used, leading to lower signal density and reduced measurement accuracy, and in scenarios where cells have different configurations and transmit powers, affecting the accuracy of RRM measurements.
Innovation Solution
The method involves configuring specific configuration information for user equipment (UE) to perform RRM measurements, including RRM measurement type, signal type, and signal combination information, allowing for independent configuration for each cell or type of measurement, enabling the use of different signals and signal combinations based on carrier types, and incorporating measurement value adjustment parameters for improved accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If reduced cell-specific reference signals (RCRS) are used in new carrier type (NCT) cells, then device complexity is reduced, but measurement precision deteriorates due to lower signal density
Solution Approach 1:
The patent introduces configuration information as an intermediary that guides the UE on which signals to use for measurement. The base station configures specific signal types (CRS, RCRS, DRS, etc.) and their combinations, allowing the system to adaptively select the most appropriate measurement signals for each cell type without increasing overall system complexity
Solution Approach 2:
The patent changes the measurement approach by allowing dynamic selection of different signal types and combinations based on cell configuration. Instead of using a fixed measurement method, the system adjusts measurement parameters (signal type, signal combination, measurement bandwidth) to match the specific cell type, thereby maintaining measurement accuracy across diverse carrier types
2Adaptability or versatility
If different cells have different configurations and transmit powers, then system adaptability is improved, but measurement precision deteriorates due to inconsistent measurement conditions
Solution Approach 1:
The patent implements dynamic measurement configuration where the base station provides cell-specific measurement configuration information to each UE. This allows measurement parameters to dynamically adapt to each cell's characteristics (configuration type, transmit power, signal density), ensuring accurate measurements despite heterogeneous cell environments
Solution Approach 2:
The patent applies local quality by allowing different measurement configurations for different cells. Each cell can have its own measurement signal type, combination, and parameters tailored to its specific characteristics, rather than using a uniform measurement approach across all cells
3Measurement precision
If multiple measurement signals and combinations are supported, then measurement precision is improved for diverse cells, but device complexity increases
Solution Approach 1:
The patent enables the UE to self-configure its measurement parameters based on configuration information provided by the base station. The UE autonomously selects appropriate measurement signals and combinations according to the received configuration, reducing the need for complex manual configuration and simplifying device operation
