Coordinated multipoint transmission is applied to multi-cell millimeter wave (mmWave) non-orthogonal multiple access (NOMA) networks in downlink transmission in this letter. Multiple cooperative base stations (BSs) jointly transmit same signal to a cell-edge user as a far user. And each BS individually serves a near user at the same beamwidth with NOMA. Subsequently, the outage probability, outage sum rate and energy efficiency are derived. Further, simulation results are provided to verify the correctness of analytical derivation and demonstrate the cell-edge user’s performance improvement as well as the superiority of BS cooperation in multi-cell mmWave NOMA networks.

基站合作下的多小区mmWave NOMA网络的性能

在此字母中，协调多点传输已应用于下行链路传输中的多小区毫米波（mmWave）非正交多址（NOMA）网络。多个协作基站（BS）共同将相同的信号发送给作为远端用户的小区边缘用户。并且每个BS都以与NOMA相同的波束宽度为近距离用户服务。随后，得出中断概率，中断总和率和能源效率。此外，提供了仿真结果以验证分析推导的正确性，并证明了小区边缘用户的性能提高以及在多小区mmWave NOMA网络中BS合作的优越性。
