Abstract
A beamforming transmission device includes a baseband processing unit, at least one radio frequency unit, and an antenna array unit. The baseband processing unit provides at least one data stream and generates a control signal according to channel state information of at least two pieces of user equipment, wherein the data stream includes data of at least two pieces of user equipment. The radio frequency unit receives the data stream signal and generates at least one radio frequency signal. The antenna array unit receives the radio frequency signal and the control signal and adjusts gains and phases of the antenna array unit according to the control signal such that the radio frequency signal can be formed as a shared beamforming signal for transmitting to at least two pieces of user equipment, wherein the shared beamforming signal includes the data of at least two pieces of user equipment.
