摘要

第五代无线通信提供了几个优点,包括高吞吐量、低延迟、大量连接、用户数量的显著改进、更高的基站容量和实现的服务质量。非正交多址是一种共享相同无线资源的有效方法,已成为第五代无线网络中实现可用带宽、用户连接和应用延迟需求的可行技术。非正交多址网络和异构网络是近年来发展起来的一种很有前途的网络基础设施,可以通过高吞吐量共享相同的资源来提高频谱容量和容纳更多的用户。这种潜在的性能使得非正交多址异构网络成为当今时代新的研究课题。本文探讨了非正交多址的概念及其在不同新兴技术中的意义。此外,本调查还系统概述了基于非正交多址异构网络的最新技术,并为上行非正交多址异构网络设计分类。此外,本调查还提供了重要的见解,并确定了考虑上行链路非正交多址异构网络的几个开放研究挑战。

Uplink non-orthogonal multiple access in heterogeneous networks: A review of recent advances and open research challenges
Fifth-generation wireless communications provide several benefits, including high throughput, lower latency, massive connectivity, considerable improvement in the number of users, higher base station capacity, and achieved quality of service. Non-orthogonal multiple access, an effective approach for sharing the same radio resources, has been highlighted as a viable technology in the fifth-generation wireless networks to achieve the demands of available bandwidth, user connectivity, and application latency. Non-orthogonal multiple access and heterogeneous networks have recently emerged as promising network infrastructures for enhancing the spectrum capacity and accommodating more users by sharing the same resources with high throughput. This potential capability has made the non-orthogonal multiple access–enabled heterogeneous networks a new research topic in the modern era. In this survey, the concept of non-orthogonal multiple access and its significance in different emerging technologies has been well explored. Furthermore, this survey covers a systematic overview of the state-of the-art techniques based on non-orthogonal multiple access–enabled heterogeneous networks and devising taxonomy for uplink non-orthogonal multiple access–enabled heterogeneous networks. In addition, this survey provides critical insights and identifies several open research challenges considering the uplink non-orthogonal multiple access–enabled heterogeneous networks.
