This paper investigates a multi-pair two-way massive MIMO amplify-andforward (AF) half-duplex relay system over Rician fading channels, where multiple pairs of users, each equipped with a single antenna, exchange information within pair through a relay with very large number of antennas. Firstly, the paper gives the zero-forcing reception/zero-forcing transmission (ZFR/ZFT) processing matrix under the conditions of perfect and imperfect channel state information (CSI) at the relay. Then, the asymptotic expressions of the end-to-end signal-to-interference-plus-noise ratio are derived. Finally, the asymptotic spectral efciency (SE) at the general power scaling schemes in the case with infnite number of relay antennas are derived and verifed by the Monte-Carlo simulations.
