摘要翻译:
本文介绍了将非正交多址(NOMA)与分布式基站(DBS)部署相结合的新方法。本研究的目的在于揭示DBS系统在NOMA环境下的真正潜力,因为以前所有关于NOMA功率最小化的工作都是在CBS(集中式基站)环境下进行的。该工作的目标是在用户速率和功率复用约束下,使每个小区的总发射功率最小化。为联合分配副载波、天线和功率设计了不同的技术,特别注意确保适度的复杂度。结果表明,相对于DBS-OMA(正交多址接入)和CBS-NOMA部署场景,通过DBS-NOMA组合获得的总发射功率有了重要的增益。

英文摘要:
This paper introduces new approaches for combining non-orthogonal multiple access (NOMA) with distributed base station (DBS) deployments. The purpose of the study is to unlock the true potentials of DBS systems in the NOMA context, since all previous works dealing with power minimization in NOMA are performed in the CBS (centralized base station) context. This work targets a minimization of the total transmit power in each cell, under user rate and power multiplexing constraints. Different techniques are designed for the joint allocation of subcarriers, antennas and power, with a particular care given to insuring a moderate complexity. Results show an important gain in the total transmit power obtained by the DBS-NOMA combination, with respect to both DBS-OMA (orthogonal multiple access) and CBS-NOMA deployment scenarios.
