未来无线系统对数据流量的需求不断增长，对5G无线通信提出了挑战性的要求，例如高频谱效率、更好的干扰管理和广泛的连接性。这些挑战开启了在未来无线电接入网络中使用NOMA方案的可能性。在这些方案中，用户在发射机中在功率域中被复用，并且在接收机中使用连续干扰消除来解复用。在这项工作中，我们提出了一种混合的资源分配技术，包括正交和非正交的无线电资源，并研究在几个建议的情况下实现的小区容量的改善。为此，我们使用基于毫米波的单小区部署来评估这种混合方案的性能。
The ever increasing demand for data traffic for future wireless systems poses challenging requirements for 5G wireless communications, such as high spectral efficiency, better interference management, and extensive connectivity. These challenges open the possibility to use NOMA schemes in future radio access networks. In these schemes, the users are multiplexed in the power domain in the transmitter and de-multiplexed using successive interference cancellation in the receiver. In this work, we propose a hybrid resource allocation technique that consists of orthogonal and non-orthogonal radio resources and also study the improvements in cell capacity achieved in several proposed cases. To this end, we use millimeter- wave-based single-cell deployment to evaluate the performance of this hybrid scheme.
