  • Method and apparatus for implementing transparent multi-user multiple-input multiple-output transmission
    Patent number: 9948369
    Abstract: Disclosed are a method and apparatus for implementing transparent multi-user multiple-input multiple-output (MU-MIMO) transmission. The method comprises: pairing at least two user equipments (UEs) according to channel estimation matrices of the UEs; configuring power of a demodulation reference signal (DMRS) of each paired UE, and configuring power of data (DATA) of each paired UE; and jointly generating a beamforming weight W according to the channel estimation matrix of each paired UE, and performing beamforming according to the power of the DMRS, the power of the DATA and the beamforming weight W, so as to generate a signal to be sent.
