Full Duplex (FD) radio has emerged as a promising solution to increase thedata rates by up to a factor of two via simultaneous transmission and receptionin the same frequency band. This paper studies a novel hybrid beamforming(HYBF) design to maximize the weighted sum-rate (WSR) in a single-cellmillimeter wave (mmWave) massive multiple-input-multiple-output (mMIMO) FDsystem. Motivated by practical considerations, we assume that the multi-antennausers and hybrid FD base station (BS) suffer from the limited dynamic range(LDR) noise due to non-ideal hardware and an impairment aware HYBF approach isadopted by integrating the traditional LDR noise model in the mmWave band. Incontrast to the conventional HYBF schemes, our design also considers the jointsum-power and the practical per-antenna power constraints. A novelinterference, self-interference (SI) and LDR noise aware optimal powerallocation scheme for the uplink (UL) users and FD BS is also presented tosatisfy the joint constraints. The maximum achievable gain of a multi-usermmWave FD system over a fully digital half duplex (HD) system with differentLDR noise levels and numbers of the radio-frequency (RF) chains isinvestigated. Simulation results show that our design outperforms the HD systemwith only a few RF chains at any LDR noise level. The advantage of havingamplitude control at the analog stage is also examined, and additional gain forthe mmWave FD system becomes evident when the number of RF chains at the hybridFD BS is small.
