LTE中的关键技术 包括OFDM 波束赋形 MIMO天仙配置等 可以让您有一定的了解-The key technologies including LTE beamforming MIMO OFDM angel configuration allows you to have some knowledge

CSI feedback allows downlink transmission to be adaptively optimized based on the instantaneous DL channel, so that closedloop beamforming and adaptive link adaptation can be enabled to optimize the system performance. The DL reference sign
