Solution Overview

Problem

Current wireless communication systems face challenges in efficiently reporting channel state information (CSI) to multiple transmission and reception points (TRPs) due to limited processing units in user equipment (UE), leading to suboptimal system performance and potential performance degradation.

Innovation Solution

The UE determines whether multiple CSI reports contain the same information and allocates processing units accordingly, updating and transmitting CSI reports based on a single calculation to minimize processing unit consumption, thereby optimizing the use of available resources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the UE updates and transmits separate CSI reports to multiple TRPs independently, then each TRP receives accurate channel state information, but the processing unit consumption increases significantly

Engineering Contradiction:

ImproveCSI reporting accuracyVSAvoidprocessing unit consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent combines multiple CSI reports that contain identical CSI information into a single update operation. When the UE determines that multiple CSI reports for different TRPs contain the same CSI information, it performs a single CSI calculation and updates all relevant reports simultaneously, thereby reducing processing unit consumption while maintaining reporting accuracy to multiple TRPs

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent applies partial action by selectively updating only the necessary CSI reports based on whether they contain identical information. Instead of independently updating each CSI report for every TRP, the UE performs updates only when needed and only for the necessary reports, reducing unnecessary processing operations

Inventive Principle:

Principle #16Partial or excessive action

2Productivity

If the UE performs independent CSI calculations for each TRP, then each CSI report is optimized for its specific TRP, but the overall system performance degrades due to limited processing units

Engineering Contradiction:

ImproveCSI reporting efficiencyVSAvoidsystem performance

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent merges the processing of multiple CSI reports by identifying when they contain identical CSI information and performing a single shared update operation. This combining approach improves processing efficiency by eliminating redundant calculations while still maintaining separate report structures for different TRPs when needed

Inventive Principle:

Principle #5Merging (Combining)

AI summary

In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE determines to report CSI reports. The UE determines that a first CSI report and a second CSI report to be reported contain same CSI information. The UE determines that total processing units required for updating the first CSI report and the second CSI report to be processing units required for updating one of the first CSI report and the second CSI report. The UE updates the first CSI report and the second CSI report based on a same CSI calculation.
