Solution Overview

Problem

Current mobile communications technologies face inefficiencies in multi-TRP/multi-panel CSI reporting, where each CSI reporting setting corresponds to one TRP, limiting the efficiency of channel state information reporting.

Innovation Solution

A method and apparatus for transmitting a multi-TRP CSI report that includes multiple CSIs to multiple TRPs, utilizing uplink channels like PUSCH and PUCCH, with parameters configured for each TRP to enhance reporting efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple CSI reporting settings are configured with each setting corresponding to one TRP, then the reporting structure is simple and manageable, but the CSI reporting efficiency is low

Engineering Contradiction:

ImproveCSI reporting efficiencyVSAvoidreporting setting configuration

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent combines multiple CSI reports corresponding to different TRPs into a single uplink transmission. The terminal device generates multiple CSI reports for different TRPs and transmits them together on the same uplink resource, merging what were previously separate reporting operations into one unified transmission, thereby improving efficiency without significantly increasing configuration complexity

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent creates a unified CSI reporting mechanism that serves multiple TRPs simultaneously. A single reporting configuration enables the terminal to report CSI for multiple TRPs through one uplink transmission, making the reporting system multi-functional rather than requiring separate dedicated reporting paths for each TRP

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Speed

If separate CSI reporting is performed for each TRP, then the reporting process is straightforward and easy to implement, but the overall reporting speed and efficiency are limited

Engineering Contradiction:

ImproveCSI reporting speedVSAvoidreporting process simplicity

Core Design Contradiction:

SpeedVSEase of operation

Solution Approach 1:

The patent merges multiple separate CSI reporting operations into a single combined transmission. Instead of sequentially reporting CSI for each TRP separately, the terminal consolidates all CSI reports into one uplink transmission, significantly increasing reporting speed while maintaining operational simplicity through unified resource allocation

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent enables continuous and simultaneous CSI reporting for multiple TRPs by establishing a unified reporting mechanism. The terminal continuously reports CSI for all configured TRPs through the same uplink resources without interruption or sequential delays, maintaining continuous useful action across all TRPs

Inventive Principle:

Principle #20Continuity of useful action
