Modern communications networks use MIMO technology to achieve high data rates.
As a special MIMO technique, beamforming also permits targeted illumination of
specific areas, making it possible to improve transmission to users at the far reaches of
cell coverage. Like other communications standards such as WLAN and WiMAXTM,
LTE also defines beamforming. Beamforming is particularly important for the time
division duplex (TDD) mode in LTE. This white paper describes the eight available
MIMO transmission modes in LTE as specified in 3GPP Release 9, as well as how
beamforming is used in LTE.
