Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If CSI reporting is configured to support diverse application scenarios, then system adaptability is improved, but hardware complexity and costs increase
Solution Approach 1:
The patent implements dynamic CSI reporting by allowing the network to flexibly configure reporting parameters through RRC signaling. The UE adapts its CSI reporting behavior based on received configuration parameters, enabling the system to dynamically adjust to different application scenarios without requiring fixed hardware configurations for each scenario.
Solution Approach 2:
The patent changes reporting parameters (such as reportQuantity, resourcesForChannelMeasurement, etc.) through RRC signaling to adapt CSI reporting to different scenarios. By modifying these parameters rather than hardware configurations, the system achieves adaptability while keeping hardware complexity low.
2Adaptability or versatility
If CSI reporting configuration is made flexible to meet different performance needs, then system versatility is improved, but device complexity increases
Solution Approach 1:
The patent creates a universal CSI reporting framework that can serve multiple application scenarios through a single configurable mechanism. The same RRC signaling-based configuration approach is used across different scenarios (e.g., carrier aggregation, dual connectivity, relay scenarios), eliminating the need for scenario-specific hardware implementations and reducing overall device complexity.
Solution Approach 2:
The patent segments the CSI reporting configuration into multiple independent RRC parameters (reportQuantity, resourcesForChannelMeasurement, etc.), each controlling a specific aspect of reporting behavior. This segmentation allows flexible combination of parameters to meet different scenario requirements without increasing overall device complexity, as each parameter can be independently configured.

AI summary
The present application discloses a method used in a node for wireless communication, and an apparatus. A first node receives a first CSI reporting configuration; receives a first signaling; and sends a first CSI. The first CSI comprises a first resource indicator and a first report quantity; the value of the first resource indicator is one of N resource indicator values; the first CSI reporting configuration comprises a first resource configuration, the first resource configuration is used to configure the N RS resources, the N RS resources respectively correspond to the N resource indicator values, the first RS resource corresponds to the value of the first resource indicator, and the first RS resource is one of the N RS resources; a protocol layer to which the first signaling belongs is a protocol layer under the RRC layer, and the first signaling is used to determine a first index set; whether calculation of the first report quantity is conditioned on the first RS resource depends on whether the first RS resource is associated with the first index set.
