摘要:

非正交多址接入(NOMA)是未来Wi-Fi的一种很有前途的技术。在上行链路NOMA中,具有不同信道条件的站通过按功率电平分割信号而在相同频率下同时发射。由于Wi-Fi使用随机接入,因此Wi-Fi中上行链路NOMA的实现面临许多挑战。本文提出了一种在Wi-Fi网络中实现同步上行NOMA的数据传输机制,其中多个站点同时开始向接入点进行数据传输。所开发的机制可以与Wi-Fi中的传统增强型分布式信道接入(EDCA)机制一起工作。仿真结果表明,与传统EDCA相比,该机制可以使总吞吐量和几何平均吞吐量增加一倍。

英文摘要:

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.
