UE CSI Report Calculation via Processing Unit Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment (UE) with limited processing capabilities faces challenges in simultaneously reporting multiple channel state information (CSI) reports effectively in wireless communication systems, as existing technologies do not adequately manage the processing units required for accurate and timely CSI reporting.
Innovation Solution
The UE determines its available processing units and selectively updates or provides CSI reports based on received triggers from the base station, prioritizing reports with higher processing unit requirements and allocating resources efficiently to ensure accurate reporting within the available processing capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the UE attempts to report multiple CSI reports simultaneously, then the reporting completeness and accuracy improve, but the processing unit requirements and device complexity increase beyond the UE's limited capabilities
Solution Approach 1:
The UE selectively reports only a subset of the triggered CSI reports based on available processing units. When processing resources are limited, the UE calculates and reports N reports out of M triggered reports, where N ≤ M and N is determined by the available processing units P. This partial action approach ensures that the UE can provide meaningful CSI feedback within its processing capabilities without being overwhelmed by the full set of reporting requirements.
2Loss of information
If the UE prioritizes reporting all triggered CSI reports, then the information completeness improves, but the processing time and resource consumption exceed the available processing capacity
Solution Approach 1:
The UE dynamically determines the number of CSI reports to report based on the currently available processing units. The parameter N (number of reports to report) is not fixed but adapts according to the available processing resources P at the time of reporting. This dynamic adjustment allows the UE to optimize between reporting completeness and processing efficiency in real-time, selecting the optimal number of reports that can be processed within the available capacity.
3Measurement precision
If the UE allocates more processing units to CSI report calculation, then the reporting accuracy and detail improve, but the available processing units for other tasks are reduced
Solution Approach 1:
The UE allocates processing units to calculate and report only a subset of the triggered CSI reports rather than all reports. By determining N ≤ M reports to report based on available processing units P, the UE achieves adequate CSI feedback for system optimization while preserving processing capacity for other essential tasks such as signal processing, protocol handling, and user data management.

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 that the UE possesses T processing units for calculation of channel state information (CSI) reports. The UE transmits, to a base station, an indication indicating the T processing units. The UE receives, from the base station, a trigger for updating or providing M CSI reports. The UE determines that P processing units of the T processing units are available for calculation of CSI reports. The UE updates or provides N CSI reports. N is an integer smaller than or equal to M and allows processing units assigned for calculation of the N CSI reports to be smaller than or equal to the P processing units.
