Cross PUCCH Group CSI Reporting Capability Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly those adhering to 3GPP standards, lack clear support for cross physical uplink control channel (PUCCH) group channel state information (CSI) reporting, leading to implementation complexity and timeline concerns for user equipment (UE) in configuring and performing CSI measurements across different PUCCH groups.
Innovation Solution
The proposed solution involves enhancing the UE's capability to report and configure cross PUCCH group CSI reporting, allowing for support on both PUCCH and physical uplink shared channel (PUSCH), with options for network configuration and UE capability indication, including per band, frequency range, and carrier type granularity, along with timeline relaxation for CSI processing to accommodate cross PUCCH group CSI reports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cross PUCCH group CSI reporting is implemented without clear standard support, then UE capability and configuration complexity increases, but implementation reliability and timeline adherence deteriorate
Solution Approach 1:
The UE autonomously determines whether to perform cross PUCCH group CSI reporting based on its capability indication and network configuration. The UE self-manages the configuration of CSI measurement resources and reporting parameters without requiring complex network control, thereby improving implementation reliability while maintaining adaptability
Solution Approach 2:
The patent introduces specific capability parameters (e.g., featureGroupIndicators, crossPUCCHGroupCSISupport) that allow the UE to indicate its support for cross PUCCH group CSI reporting. These parameter changes enable flexible adaptation to different network configurations while maintaining clear implementation boundaries
2Adaptability or versatility
If cross PUCCH group CSI reporting is supported without clear timeline definitions, then reporting flexibility improves, but processing timeline management deteriorates
Solution Approach 1:
The UE performs capability indication and configuration setup in advance through RRC signaling before actual cross PUCCH group CSI reporting occurs. This preliminary action establishes clear timeline expectations and processing requirements, preventing time loss during actual operation while maintaining reporting flexibility
Solution Approach 2:
The patent segments the cross PUCCH group CSI reporting process into distinct phases: capability indication, configuration setup, measurement execution, and report transmission. Each phase has defined timing requirements, which segments the overall timeline management into manageable portions while maintaining flexibility
3Manufacturing precision
If detailed capability indication per band and carrier type is implemented, then configuration precision improves, but device complexity increases
Solution Approach 1:
The patent applies local quality by allowing the UE to indicate capability support specifically for certain frequency ranges (FR1, FR2), band combinations, and carrier types rather than uniformly across all configurations. This localized capability indication provides configuration precision where needed while avoiding unnecessary complexity in unsupported areas
Data Source
AI summary
A user equipment (UE) performs capability exchange for indicating support of cross physical uplink control channel (PUCCH) group channel state information (CSI) reporting. In some embodiments, the UE receives a request from a network for the UE capability exchange and reports to the network whether cross PUCCH group CSI reporting is supported. The UE may also indicate whether a processing timeline for CSI reporting is to be relaxed to accommodate the cross PUCCH group CSI measurement and reporting.
