摘要
Systems and methods for user specific antenna down tilt in wireless cellular networks are disclosed. A preferred embodiment method comprises synthesizing a plurality of virtual antennas from a single physical antenna, wherein a total number of virtual antennas is less than a total number of antenna elements in the physical antenna, transmitting pilot signals on the plurality of virtual antennas, receiving, from a user equipment, a pre-coding control indicator based on the transmitted pilot signals, determining a multiple-input multiple output pre-coding vector based on the pre-coding control indicator, and transmitting user data modulated by the pre-coding vector to the user equipment via the plurality of virtual antennas.
