LTE Beamforming Measurements

Multiple input multiple output (MIMO) technology is an integral part of 3GPP E-UTRA long term evolution (LTE). As part of MIMO, beamforming is also used in LTE. This application note provides a brief summary of the transmission modes (TM) in LTE and describes the beamforming measurements for base stations (BS) and user equipment (UE). The…
