论文摘要
第三代合作伙伴项目开始研究2021年的第18版。人工智能（AI）空气界面是第18版的关键特征之一，其中选择了用于渠道状态信息（CSI）反馈增强的AI作为代表性用途案例。本文概述了5G助长中CSI反馈增强的AI。首先引入并比较了几种代表性的非AI和AI支持的CSI反馈框架。然后，详细介绍了5G高级反馈增强的AI标准化。首先，提出并讨论了5G高增强中CSI反馈增强的AI范围。然后，确定和讨论了针对CSI反馈增强的AI标准化标准化的主要挑战和开放问题，尤其是专注于绩效评估以及针对AI支持的CSI反馈的新协议的设计。本文为基于AI的CSI反馈增强的标准化研究提供了指南。
The 3rd Generation Partnership Project started the study of Release 18 in 2021. Artificial intelligence (AI)-native air interface is one of the key features of Release 18, where AI for channel state information (CSI) feedback enhancement is selected as the representative use case. This article provides an overview of AI for CSI feedback enhancement in 5G-Advanced. Several representative non-AI and AI-enabled CSI feedback frameworks are first introduced and compared. Then, the standardization of AI for CSI feedback enhancement in 5G-advanced is presented in detail. First, the scope of the AI for CSI feedback enhancement in 5G-Advanced is presented and discussed. Then, the main challenges and open problems in the standardization of AI for CSI feedback enhancement, especially focusing on performance evaluation and the design of new protocols for AI-enabled CSI feedback, are identified and discussed. This article provides a guideline for the standardization study of AI-based CSI feedback enhancement.
