Abstract:

MIMO enhancement was studied and investigated out of five key technologies in LTE-Advanced system. Based on the technique theory, algorithm implement and test trail of transmission mode 9 were well disscussed. The utilization method, performance advantages and network compatibility of transmission mode 9 were also analyzed. Furthermore, all downlink transmission modes of LTE and LTE-Advanced were compared, and some suggestions were provided for network planning.

Key words: LTE-Advanced, MIMO, transmission mode, beamforming
