论文摘要
为了解决第五代（5G）无线网络中的覆盖范围和容量挑战，该中继技术被认为是有前途的解决方案，最近引起了学术界的极大关注。多路继电器通道（MRC）是继电器网络的基本构建块，它定义了继电器节点及其相邻节点之间所有可能的信息流模式的家庭。结合几种新技术，例如物理层网络编码（PLNC），信号和干扰一致性，多输入多输出（MIMO）等，MRC具有较高的能力，可帮助多用户信息交换。在本文中，我们旨在从信息理论和传播理论研究的角度提供有关MRC最新技术的全面概述。总结并讨论了关键结果，以确定MRC的当前研究进度。还讨论了开放问题和研究挑战，以刺激未来对MRC的研究。
To address the coverage and capacity challenges in fifth-generation (5G) wireless networks, the relay technique has been considered as a promising solution and recently attracted great attentions from academia. The multiway relay channel (mRC), which serves as a fundamental building block of a relay network, defines the family of all possible information-flow patterns between a relay node and its neighboring nodes. Combined with several new techniques, such as physical-layer network coding (PLNC), signal and interference alignments, multi-input multi-output (MIMO), etc., the mRC exhibits superior capability to assist multiuser information exchange. In this article, we aim to provide a comprehensive overview on the state-of-the-art of the mRC from the perspectives of both information-theoretic and communication-theoretic studies. The key results are summarized and discussed to identify the current research progress of the mRC. Open problems and research challenges are also discussed to spur future research towards the mRC.
