Abstract
According to embodiments of the present disclosure, downlink beamforming in MU-MIMO systems is proposed. Embodiments of the present disclosure take practical receivers into consideration, to further mitigate the interferences sensed by terminal devices. The beamforming scheme according to embodiments of the present disclosure has many advantages. For example, embodiments of the present disclosure tackle interferences from terminal device view, to mitigate the interferences which really affect the received signals of terminal devices. Embodiments of the present disclosure do not assume that terminal devices utilize Eigen receivers but consider more practical receivers used by the terminal devices to mitigate the interferences. Embodiments of the present disclosure have high flexibility, different interference cancelling methods can be used to replace the ZF method.
