Joint beamforming and broadcasting in Massive MIMO
Joint beamforming and broadcasting in Massive MIMO
The downlink of a massive MIMO system is considered for the case in which the base station must concurrently serve two categories of terminals: one group to which imperfect instantaneous channel state information (CSI) is available, and one group to which no CSI is available. Motivating applications include broadcasting of public channels and control information in wireless networks.
