Full duplex (FD) is an auspicious wireless technology that holds thepotential to double data rates through simultaneous transmission and reception.This paper proposes two innovative designs of hybrid beamforming (HYBF) for amulticell massive multiple-input-multiple-output (mMIMO) millimeter wave(mmWave) FD system. Initially, we introduce a novel centralized HYBF (C-HYBF)scheme, which employs the minorization-maximization (MM) method. However, whilecentralized beamforming designs offer superior performance, they suffer fromhigh computational complexity, substantial communication overhead, and demandexpensive computational resources. To surmount these challenges, we present aframework that facilitates per-link parallel and distributed HYBF (P&D- HYBF)in the mmWave frequency band. This cooperative approach enables each basestation (BS) to independently solve its local, low-complexity sub-problems inparallel, resulting in a substantial reduction in communication overhead andcomputational complexity. Simulation results demonstrate that P&D-HYBF achievescomparable performance to C-HYBF, and with only a few radio-frequency (RF)chains, both designs surpass the capabilities of fully digital half duplex (HD)systems.
