Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in generating accurate CSI reports due to the lack of consideration for different application scenarios, such as varying ports, beams, and spatial characteristics, leading to inefficiencies and increased hardware complexity.
Innovation Solution
A unified design scheme is adopted for generating CSI reports, considering different scenarios like multi-antenna and single-antenna panels, using CSI configuration information to indicate RS resources and port groups, and calculating CQI based on specific RS resource measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate design schemes are adopted for different application scenarios (multi-antenna panels, single-antenna panels), then the accuracy of CSI reports is improved by accounting for specific scenario characteristics, but the device complexity and hardware cost increase
Solution Approach 1:
The patent applies universality by designing a unified CSI report generation mechanism that can handle multiple application scenarios (multi-antenna panels, single-antenna panels, different port configurations) through a single flexible framework. The base station configures CSI report settings that adapt to different scenarios without requiring separate hardware or processing paths, making the system universally applicable while maintaining scenario-specific accuracy
Solution Approach 2:
The patent implements dynamics by enabling the base station to dynamically configure and switch between different CSI report generation modes based on the actual application scenario. The system can adaptively adjust the CSI report content, port groupings, and measurement configurations according to whether multi-antenna or single-antenna panels are being used, providing optimal performance for each scenario without fixed hardware constraints
2Adaptability or versatility
If multiple index sets and port groups are configured to handle diverse scenarios, then the adaptability of the system is improved, but the configuration complexity and processing overhead increase
Solution Approach 1:
The patent applies segmentation by dividing the CSI processing into distinct logical components: multiple index sets for different port groups, separate CQI calculation paths for different scenarios, and modular configuration elements. This segmentation allows the system to handle diverse scenarios through organized, manageable units rather than monolithic complex structures, reducing processing overhead while maintaining adaptability
Solution Approach 2:
The patent utilizes parameter changes by allowing the base station to configure different parameters (number of port groups, index set assignments, CQI calculation methods) based on the specific application scenario. The system transitions between different operational modes by changing configuration parameters rather than requiring fundamentally different processing architectures, thereby achieving high adaptability with controlled complexity

AI summary
The present application discloses a method and an apparatus used in a node for wireless communication. A first node receives first CSI configuration information; receives first signaling; receives a first RS resource; and sends a first CSI report. The first CSI configuration information is used for indicating the first RS resource. Measurement for the first RS resource is for generating the first CSI report. The first CSI configuration information is used for indicating M index sets, wherein M is a positive integer greater than 1. Any one of the M index sets comprises at least one index group. Any index group in the M index sets comprises at least one index. Any index in the M index sets is used for indicating one port of the first RS resource. Any index group in the M index sets corresponds to one rank. The first signaling is used for determining a first port group. According to the present application, the efficiency is improved, and the system implementation complexity is reduced.
