RRM Measurement Configuration for RedCap Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication technologies lack a standardized method for performing radio resource management (RRM) measurements based on both cell defining synchronized signal blocks (CD-SSBs) and non-cell defining synchronized signal blocks (NCD-SSBs), particularly for reduced capability (RedCap) terminals with limited bandwidth.
Innovation Solution
A measurement method and apparatus that allow user equipment to perform RRM measurements based on measurement configuration parameters, which include indicators for both CD-SSB and NCD-SSB measurements. This method enables user equipment to perform RRM measurements using either CD-SSBs or NCD-SSBs, or both, depending on the configuration parameters received from the network device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If RedCap terminals perform RRM measurements based on CD-SSB only, then measurement standardization is maintained, but measurement flexibility and effectiveness are reduced for limited bandwidth scenarios
Solution Approach 1:
The measurement configuration is segmented into separate parameters for CD-SSB measurement and NCD-SSB measurement. The network device can independently configure measurement objects, reporting configurations, and other measurement parameters for each SSB type, allowing flexible combination rather than treating them as a single unified measurement process.
Solution Approach 2:
The measurement configuration parameters are made dynamic and adjustable. The network device can flexibly configure whether the terminal performs measurement based on CD-SSB, NCD-SSB, or both, depending on the specific scenario and terminal capabilities. This dynamic configuration enables adaptation to different bandwidth conditions and network requirements.
2Reliability
If RedCap terminals use NCD-SSB for measurement, then measurement effectiveness improves for limited bandwidth, but lack of standardized method reduces reliability
Solution Approach 1:
The measurement method is designed to be universal, supporting both CD-SSB-based measurement and NCD-SSB-based measurement within a single standardized framework. The terminal can perform measurements based on either SSB type or both simultaneously, depending on configuration, making the measurement system multi-functional and adaptable to different terminal types and scenarios.
Solution Approach 2:
The invention introduces configurable parameters that control the measurement behavior. By changing parameters such as measurement object configuration, SSB type indication, and reporting configuration, the system can adapt between standardized CD-SSB measurement and effective NCD-SSB measurement, resolving the contradiction through parameter-driven flexibility.
3Adaptability or versatility
If measurement configuration supports both CD-SSB and NCD-SSB, then measurement flexibility improves, but configuration complexity increases
Solution Approach 1:
The configuration is divided into modular, independent parameters for CD-SSB and NCD-SSB measurements. Each measurement type has its own measurement object configuration, SSB type indication, and reporting configuration parameters, allowing the network device to configure only what is needed for each specific scenario rather than managing a monolithic complex configuration.
