...With massive MIMO at the BS, the user pilot sequence assignment still follows (3), which is the same as the case with one antenna at the BS....

...We show that massive multiple-input multiple-output (MIMO) is especially well-suited for massive IoT connectivity in the sense that the device detection error can be driven to zero asymptotically in the limit as the number of antennas at the base station goes to infinity by using the multiple-measurement vector (MMV) compressed sensing techniques....
[...]
...From the compressed sensing perspective, device activity detection in massive MIMO systems corresponds to the MMV problem, which generalizes the sparse signal recovery problem to the case with a group of measurement vectors for a group of signal vectors that are assumed to be jointly sparse and share a common support....

...It is of both theoretical and practical importance to investigate the role of massive MIMO on massive IoT connectivity, which is the aim of this section....

...In the following, we discuss how to generalize the AMP based algorithm in Section III to the massive MIMO scenario and to quantify its significant improvement in device activity detection accuracy over the single-antenna BS case....
