The aim of this work is to propose new approaches for maximizing the energyefficiency of downlink 5G mobile communication systems, in the presence of areactive jammer. The concepts of non-orthogonal multiple access (NOMA) anddistributed antenna systems (DAS) are exploited to devise joint subband, powerand antenna assignment techniques, so as to guarantee a certain quality ofservice (QoS) to users. Also, the scheduler relies on jamming statistics,observed at the end of each timeslot, to perform resource allocation based onthe prediction of the jammer behavior over the next timeslot. A particular careis given, in the proposed techniques, to maintain a moderate complexity at thereceiver level, and to limit the number of active RRHs (remote radio heads) inthe cell. Simulation results show that a proper combination of NOMA with DAScan allow a significant enhancement of the system robustness to jamming, withrespect to centralized antenna systems and orthogonal multiple access.
