Abstract
Beamforming in massive MIMO networks includes monitoring a signal condition such as pathloss of wireless devices and, based thereon, selecting a type of reference signal for the wireless devices, the type selected from among a non-precoded reference signal, a beamformed reference signal, or a standard reference signal. Further, an MCS of the wireless devices is monitored and, based thereon, the type of reference signal is adjusted.
