Solution Overview

Problem

Existing CSI reporting mechanisms in wireless communication systems are inefficient and resource-intensive due to the lack of optimization in configuring multiple report metrics for multiple resource sets, leading to suboptimal channel state information reporting.

Innovation Solution

A method and system for wireless communication that involves transmitting a configuration message with multiple report metrics associated with different CSI resource sets from multiple antenna panels, allowing for efficient CSI reporting by measuring and reporting channel state information based on these metrics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple configuration messages are transmitted to convey multiple report metrics for multiple CSI resource sets, then the CSI reporting accuracy and completeness is improved, but the signaling overhead and resource consumption increases

Engineering Contradiction:
ImproveCSI reporting accuracyVSAvoidsignaling overhead
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent combines multiple report metrics (CQI, PMI, RI) for multiple CSI resource sets into a single configuration message transmitted from base station to UE. This consolidation maintains complete CSI reporting capability while reducing the number of separate configuration messages, thereby lowering signaling overhead and resource consumption.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The configuration message is designed with multi-functionality to convey multiple report metrics simultaneously. A single configuration message structure is created that can accommodate different report quantities (CQI, PMI, RI) for multiple CSI resource sets, making the signaling mechanism universal and efficient rather than requiring separate dedicated messages for each metric.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Manufacturing precision

If multiple separate configuration messages are used for different report metrics, then the configuration detail and precision is improved, but the configuration complexity and processing overhead increases

Engineering Contradiction:
Improveconfiguration detailVSAvoidconfiguration complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

Within the single configuration message, different report metrics (CQI, PMI, RI) for different CSI resource sets are segmented into distinct fields or elements. This allows the UE to parse and process each metric independently while receiving them through a unified message structure, maintaining configuration precision without increasing overall message complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent merges multiple configuration operations into a single configuration message that the UE can process atomically. This reduces the complexity of handling multiple separate configuration procedures, while the internal structure of the message maintains sufficient detail and precision for accurate configuration of all report metrics.

Inventive Principle:
Principle #5Merging (Combining)

3Measurement precision

If CSI reporting is configured for multiple antenna panels with multiple resource sets, then the channel state information quality is improved, but the resource utilization efficiency deteriorates

Engineering Contradiction:
Improvechannel state information qualityVSAvoidresource utilization efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The single configuration message serves multiple functions by configuring report metrics for multiple antenna panels and CSI resource sets simultaneously. This multi-functional approach enables comprehensive CSI reporting across all panels and resource sets without requiring separate configuration procedures, thereby improving resource utilization efficiency while maintaining high CSI quality.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The base station performs preliminary configuration of all report metrics for multiple antenna panels and resource sets in a single configuration message before actual CSI measurement and reporting begins. This preliminary comprehensive configuration enables the UE to efficiently perform measurements across all resource sets without needing repeated configuration exchanges, improving resource utilization while ensuring high CSI quality.

Inventive Principle:
Principle #10Preliminary action

AI summary

Aspects relate to configuration for channel state information (CSI) signaling. For example, a base station may transmit, to a user equipment (UE), a configuration message indicating report metrics, where each of the report metrics is associated with at least one corresponding CSI resource set of CSI resource sets associated with antenna panels configured for communication with the UE. The base station may further transmit at least one reference signal via at least one of the antenna panels to the UE in accordance with the configuration message. The base station may further receive, from the UE, a CSI report that includes report quantity values respectively associated with the report metrics, where the report quantity values are based on measurement of the at least one reference signal according to the configuration message.
