CSI Report Processing for Missing RS Time Windows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, the absence of reference signal resources in certain time windows affects the processing of CSI reports, leading to inaccuracies and resource inefficiencies.
Innovation Solution
A method for configuring CSI reports that accounts for the presence or absence of RS resources in time windows, allowing for accurate CSI report processing by determining whether to transmit or receive the report based on the availability of RS resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If CSI report processing is performed without considering RS resource availability, then the processing is simple and continuous, but the CSI report accuracy deteriorates when RS resources are not transmitted
Solution Approach 1:
The patent applies dynamics by making the CSI processing mode variable based on RS resource availability. The system dynamically switches between first processing mode (when RS resources are transmitted) and second processing mode (when RS resources are not transmitted), allowing the processing complexity to adapt to actual transmission conditions rather than remaining fixed.
Solution Approach 2:
The patent changes the processing parameters by introducing different processing modes with distinct characteristics. The first processing mode uses normal CSI processing when RS resources are available, while the second processing mode uses alternative processing when RS resources are unavailable, thereby maintaining accuracy across varying transmission conditions.
2Productivity
If CSI reports are transmitted regardless of RS resource availability, then the reporting is continuous, but system resources are wasted when no RS resources are transmitted
Solution Approach 1:
The patent makes the CSI reporting behavior dynamic by conditionally triggering reports based on RS resource transmission status. When RS resources are transmitted, the first processing mode generates and transmits CSI reports. When RS resources are not transmitted, the second processing mode suppresses or modifies reports, thereby avoiding unnecessary resource consumption while maintaining productivity when needed.
Solution Approach 2:
The patent changes the reporting parameter by introducing conditional reporting based on transmission conditions. The system adjusts the reporting behavior parameter according to whether RS resources are transmitted, switching between active reporting (first mode) and suppressed/report-modified behavior (second mode), thus optimizing the balance between productivity and energy efficiency.
3Adaptability or versatility
If the system always expects RS resources to be transmitted, then the CSI processing is straightforward, but the system cannot adapt to energy-saving modes with missing RS resources
Solution Approach 1:
The patent applies dynamics by implementing adaptive processing that responds to actual transmission conditions. The system dynamically identifies whether RS resources are transmitted and switches processing modes accordingly, enabling adaptability to energy-saving modes without requiring a completely redesigned processing architecture.
Solution Approach 2:
The patent uses preliminary action by pre-configuring both processing modes before actual transmission occurs. The system prepares the first processing mode for normal operation and the second processing mode for energy-saving conditions, allowing rapid switching when transmission conditions change without requiring real-time complex decision-making.

AI summary
Disclosed in the present application are a method and apparatus used in a node for wireless communication. A first node receives a first CSI report configuration, the first CSI report configuration being used for configuring a first RS resource set, and the first RS resource set comprising at least one RS resource configured for at least one of channel measurement or interference measurement. A first physical layer channel is configured for the first CSI report; the first RS resource set comprises, in a time domain, some or all time domain resources in a first time window; the processing for the first CSI report on the first physical layer channel depends on whether the first RS resource set is executed in the first time window or not; and the execution is transmission, or the execution is reception.
