In this letter, we investigate the outage performance of a joint transmission coordinated multipoint cooperative non-orthogonal multiple access (JT-CoMP-CNOMA) network. It is assumed that there is no direct links between the base stations and the cell-edge user, and thus the cell-centre users act as relays for the cell-edge user. The cell-centre users are assumed to be energy-constrained and adopt the simultaneous wireless information and power transfer (SWIPT) for decoding information and harvesting energy for forwarding. The closed-form approximate expressions for the outage probabilities of the users are derived. The theoretical results are verified by conducting Monte-Carlo simulations. It is shown that significant performance gain for the cell-edge user is achieved by JT-CoMP-CNOMA compared to the conventional CNOMA and the CoMP-CNOMA with opportunistic scheduling.

带SWIPT的JT-CoMP-CNOMA网络的中断性能

在这封信中，我们研究了联合传输协调多点协作非正交多址（JT-CoMP-CNOMA）网络的中断性能。假定在基站和小区边缘用户之间没有直接链路，因此小区中心用户充当小区边缘用户的中继。假设小区中心的用户能量受限，并且采用同时无线信息和功率传输（SWIPT）来解码信息并收集能量以进行转发。得出用户中断概率的封闭式近似表达式。通过进行蒙特卡洛模拟验证了理论结果。
