CSI Report Ordering for Multi-TRP Uplink Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies face challenges in efficiently managing multiple channel state information (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, ensuring proper transmission on physical uplink shared channels (PUSCH) or physical uplink control channels (PUCCH), with priority functions adapted to handle multiple CSI reports within a single CSI report configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple CSI reports are configured within a single CSI report configuration for multi-TRP communication, then the system can support non-coherent joint transmission and improve communication reliability, but the complexity of managing and prioritizing multiple CSI reports increases significantly
Solution Approach 1:
The patent segments the management of multiple CSI reports by introducing distinct priority levels (first priority and second priority) for different CSI reports within a single configuration. This segmentation allows the system to handle multiple reports by categorizing them into priority groups, thereby managing complexity through structured classification while maintaining support for non-coherent joint transmission in multi-TRP scenarios.
2Adaptability or versatility
If existing priority functions and omission rules are used for multiple CSI reports, then the system maintains compatibility with existing protocols, but the handling of multiple CSI reports becomes inadequate and inefficient
Solution Approach 1:
The patent introduces dynamic priority-based ordering mechanisms that adapt to different communication scenarios. The system dynamically determines the transmission order of multiple CSI reports based on their assigned priorities, allowing flexible handling of first priority and second priority reports. This dynamic approach improves handling efficiency while maintaining protocol compatibility through adaptive prioritization rather than rigid fixed-order processing.
3Ease of operation
If multiple CSI reports are transmitted without proper ordering and encoding rules, then the transmission process is simplified, but the system cannot properly handle UCI omission and transmission on PUSCH/PUCCH channels
Solution Approach 1:
The patent applies preliminary action by establishing encoding and ordering rules for multiple CSI reports before actual transmission occurs. The system pre-defines priority levels and transmission ordering for first priority and second priority CSI reports, ensuring that when transmission is needed on PUSCH or PUCCH channels, the proper sequence and encoding are already determined. This preliminary structuring maintains reliability for UCI transmission while keeping the actual transmission process straightforward.

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.
