Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing wireless communication systems face challenges in efficiently managing multiple CSI reports, particularly in scenarios requiring non-coherent joint transmission (NCJT) CSI reporting for multi-TRP communication, where existing priority functions and omission rules do not adequately handle multiple CSI reports within a single CSI report configuration.

Innovation Solution

The proposed solution involves separately encoding and ordering multiple CSI reports based on predefined rules, allowing for their transmission on a physical uplink shared channel (PUSCH) or physical uplink control channel (PUCCH), with priority functions enhanced to account for the relative priorities of these reports and UCI omission rules.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple CSI reports are configured in a single CSI report configuration for non-coherent joint transmission, then the adaptability and versatility of the system is improved, but the device complexity and difficulty of managing the reports increases

Engineering Contradiction:

Improvesupport for non-coherent joint transmission and multi-TRP communicationVSAvoidcomplexity of managing multiple CSI reports

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the multiple CSI reports within a single configuration by introducing distinct report identities (first CSI report, second CSI report) with separate encoding and ordering rules. This segmentation allows the system to handle multiple reports systematically through defined procedures for priority determination, encoding, and transmission, thereby managing complexity while supporting versatile multi-TRP communication scenarios

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If existing priority functions and omission rules are used for multiple CSI reports, then the ease of operation is maintained, but the reliability of CSI report handling deteriorates due to inadequate handling of multiple reports

Engineering Contradiction:

Improvesimplicity of existing priority functionsVSAvoidadequacy of priority functions and omission rules

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent applies preliminary action by establishing encoding and ordering rules before the actual CSI report transmission. The UE determines the order of multiple CSI reports based on predefined criteria (such as report configuration indices, priority levels, or transmission timing) and encodes them accordingly in advance. This preliminary structuring ensures that when reports are transmitted on PUSCH or PUCCH, the base station can reliably decode and process them without requiring complex real-time decision-making, thus maintaining ease of operation while improving reliability

AI summary

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a channel state information (CSI) report configuration that includes configuration information associated with multiple CSI reports. The UE may generate a CSI report message in which the multiple CSI reports are separately encoded and ordered based at least in part on one or more rules. In some aspects, the CSI report message may be generated for transmission on one or more of a physical uplink shared channel (PUSCH) or a physical uplink control channel (PUCCH). Numerous other aspects are provided.
