Technology forecasts anticipate a new era in which massive numbers of humans, machines, and things are connected to wireless networks to sense, process, act, and communicate with the surrounding environment in a real-time manner. To make the visions come true, the sixth generation (6G) wireless networks should be hyper-connected, implying that there are no constraints on the data rate, coverage, and computing. In this article, we first identify the main challenges for 6G hyperconnectivity, including terabits-per-second (Tbps) data rates for immersive user experiences, zero coverage-hole networks, and pervasive computing for connected intelligence. To overcome these challenges, we highlight key enabling technologies for 6G such as distributed and intelligence-aware cell-free massive multi-input multi-output (MIMO) networks, boundless and fully integrated terrestrial and non-terrestrial networks, and communication-aware distributed computing for computationintensive applications. We further illustrate and discuss the hyper-connected 6G network architecture along with open issues and future research directions.

迈向 6G 超连接：愿景、挑战和关键支持技术

技术预测预计将迎来一个新时代，大量人类、机器和物体将连接到无线网络，以实时方式感知、处理、行动并与周围环境进行通信。为了实现这一愿景，第六代 (6G) 无线网络应该是超连接的，这意味着数据速率、覆盖范围和计算不受限制。在本文中，我们首先确定 6G 超连接的主要挑战，包括用于沉浸式用户体验的太比特每秒 (Tbps) 数据速率、零覆盖盲区网络以及用于互联智能的普适计算。为了克服这些挑战，我们重点介绍 6G 的关键支持技术，例如分布式和智能感知的无蜂窝大规模多输入多输出 (MIMO) 网络，无限制且完全集成的陆地和非陆地网络，以及用于计算密集型应用的通信感知分布式计算。我们进一步说明和讨论超连接 6G 网络架构以及未解决的问题和未来的研究方向。
