Massive MIMO beamforming is an essential technique for 5G and beyond 5G systems. In this paper, we try to give a theoretical foundation to the massive MIMO beamforming from the principle of a multi-user joint transmit-receive diversity (JTRD). Multi-user JTRD is designed to maximize each user’s composite MIMO channel gain. It is shown that multi-user JTRD using linear array at a base station (BS) is equivalent to full/hybrid beamforming. The received signal-to-noise ratio (SNR) expression is derived for a given multi-user MIMO channel. Then, the 2-user link capacity in a Rayleigh fading environment is evaluated by Monte-Carlo numerical computation method.
