Abstract
Embodiments described herein include devices, methods, and instructions for managing beam interpolation in massive multiple-input multiple-output (MIMO) communications. In one example embodiment, an evolved node B is configured to transmit to a UE using massive MIMO by transmitting multiple beamformed reference signals on multiple transmission beams each associated with a different plurality of antennas. The eNB receives beam interpolation information back from the UE, and then generates a data transmission that is sent to the UE using an interpolated transmission beam from a first and second transmission beam.
