A joint time allocation and energy beamforming method for the maximisation of the system energy efficiency (EE) in multi-user multi-cell wireless powered communication network (WPCN) with distributedmassive multi-input multi-output (DM-MIMO) system is proposed. An iterative algorithm to solve the EE maximisation problem is proposed. The simulation results show that the proposed scheme can achieve a significant EE gain. Further, it reveals that the achievable sum capacity of the DM-MIMO is considerably higher than that of a conventional centralised massive multi-input multi-output system.
