Satellite-Assisted Cell-Free Massive MIMO Systems with Multi-Group Multicast

Satellite-Assisted Cell-Free Massive MIMO Systems with Multi-Group Multicast

In this paper, we use satellite-assisted and multi-group multicast mechanisms to relieve ground traffic pressure and improve data transmission efficiency of cell-free massive MIMO systems. We propose to estimate channel state information (CSI) by common pilot scheme. Given the estimated CSI, we deri...
