IN RECENT years, massive MIMO systems, where the base station (BS) is equipped with hundreds antennas, emerge as one key concept for the next generation wireless systems. Massive MIMO can achieve all merits of conventional MIMO systems with a much greater scale . In addition, as the number of BS antennas increases to infinity, the intra-cell interference and the noise can be averaged out due to the law of large numbers . There have been many results on different aspects of massive MIMO –. As to the performance analysis of massive MIMO, existing work focused on the sum-rate –, where the asymptotic deterministic equivalence of the signal-to-interference-plusnoise ratio (SINR) was derived for different massive MIMO scenarios. However, there are little results on other important performance measure such as the outage probability. We found three papers – related to the outage analysis. In , the secrecy outage capacity of a massive MIMO relaying system was studied, where the SINR at the eavesdropper is approximated based on channel hardening and an approximate SINR distribution was derived. In , the secrecy outage probability of multi-cell massive MIMO systems was analyzed, where the SINR at the eavesdropper was shown to be equivalent to the SINR of a multiple-branch minimum-mean-square-error diversity combiner. For a point-to-point massive MIMO channel,  proved that the mutual information approaches Gaussian as the dimension increases, and the outage probability was approximated using the Q-function.
