论文摘要
非正交多访问（NOMA）是未来Wi-Fi的有前途的技术。在上行链路NOMA中，具有不同通道条件的站点通过功率水平将信号分解为同时以相同的频率传输。由于Wi-Fi使用随机访问，因此WI-FI中上行链路Noma的实施面临许多挑战。本文在Wi-Fi网络中提出了一个数据传输机制，该机制可以使同步上行链路NOMA，其中多个站点同时启动数据传输到访问点。开发的机制可以与Wi-Fi中的传统增强分布式通道访问（EDCA）机制一起使用。通过模拟，与传统EDCA相比，开发的机制可以使总吞吐量和几何平均吞吐量增加一倍。
Non-Orthogonal Multiple Access (NOMA) is a promising technology for future Wi-Fi. In uplink NOMA, stations with different channel conditions transmit simultaneously at the same frequency by splitting the signal by power level. Since Wi-Fi uses random access, the implementation of uplink NOMA in Wi- Fi faces many challenges. The paper presents a data transmission mechanism in Wi-Fi networks that enables synchronous uplink NOMA, where multiple stations start data transmission to the access point simultaneously. The developed mechanism can work with the legacy Enhanced Distributed Channel Access (EDCA) mechanism in Wi-Fi. With simulation, it is shown that the developed mechanism can double the total throughput and geometric mean throughput compared with the legacy EDCA.
