这封信研究了非正交多址接入（NOMA）在多小区下行毫米波（mmWave）网络中的性能。一个泊松簇点过程被用来模拟所考虑的系统。毫米波网络的关键特征，如定向波束形成和距离相关的视线/非视线，被考虑在内。Nakagami衰落被认为是小尺度衰落。NOMA用户实现的中断概率的封闭形式的表达式。仿真结果证明了分析结果的准确性，也表明NOMA可以在多小区毫米波网络中优于OMA。
This letter investigates the performance of non-orthogonal multiple access (NOMA) in a multi-cell downlink millimeter-wave (mmWave) network. A Poisson cluster point process is utilized to model the considered system. Key features of mmWave networks, such as directional beamforming and distance-dependent line of sight/non-line of sight, are taken into consideration. Nakagami fading is considered for small-scale fading. Closed-form expressions for outage probabilities achieved by the NOMA users are obtained. Simulation results are provided to demonstrate the accuracy of the analytical results and also show that NOMA can outperform OMA in a multi-cell mmWave network.
