论文摘要
非正交多访问（NOMA）是一种有希望的多访问技术，可以提高5G和超越蜂窝网络的用户的吞吐量和光谱效率。同样，协调的多点传输和接收（COMP）是一种改善细胞边缘用户覆盖率的现有技术。因此，Noma与Comp一起可能会增强用户的吞吐量和覆盖范围。但是，COMP和NOMA的实施顺序可能会对超密集网络（UDNS）的系统性能产生重大影响。在此激励的情况下，我们通过提出两种用户分组和配对方案来研究基于COMP和NOMA的UDN的性能，这些方案在一组用户进行COMP和NOMA的顺序上有所不同。将详细的仿真结果与最先进的系统与不同的用户和基站密度进行了比较，将提出的模拟结果进行比较。通过数值结果，我们表明所提出的方案可用于实现UDNS中合适的覆盖范围折衷权衡。
Non-orthogonal multiple access (NOMA) is a promising multiple access technology to improve the throughput and spectral efficiency of the users for 5G and beyond cellular networks. Similarly, coordinated multi-point transmission and reception (CoMP) is an existing technology to improve the coverage of cell-edge users. Hence, NOMA along with CoMP can potentially enhance the throughput and coverage of the users. However, the order of implementation of CoMP and NOMA can have a significant impact on the system performance of Ultra-dense networks (UDNs). Motivated by this, we study the performance of the CoMP and NOMA based UDN by proposing two kinds of user grouping and pairing schemes that differ in the order in which CoMP and NOMA are performed for a group of users. Detailed simulation results are presented comparing the proposed schemes with the state-of-the-art systems with varying user and base station densities. Through numerical results, we show that the proposed schemes can be used to achieve a suitable coverage-throughout trade-off in UDNs.
