Performance of Multi-Cell mmWave NOMA Networks With Base Station Cooperation
Yangying Zhang, Junsheng Mu, Xiaojun Jing
Abstract
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.
