Power Minimization for Cell-Free Massive MIMO
2019 IEEE International Conference on Consumer Electronics - Taiwan (ICCE-TW), 2019In this paper, we investigate the total power minimization problem for the downlink cell-free massive multiple- input multiple-output (mMIMO) system, subjecting to the users' quality-of-service (QoS) constraint. Specifically, the total power consists of circuit power, data transmission power, and backhaul power.

NOMA-Aided Cell-Free Massive MIMO Systems
IEEE Wireless Communications Letters, 2018A cell-free massive multiple-input multiple-output system with non-orthogonal multiple-access (NOMA) is investigated. An achievable sum rate is derived and compared against the orthogonal multiple access (OMA) counterpart. Thereby, the detrimental effects of intra-cluster pilot contamination, inter-cluster interference and imperfect successive ...
