Abstract: This disclosure relates to the field of communications technologies, and discloses a configuration information transmission method, apparatus, and system. The method includes: determining, by a base station, configuration information corresponding to a target group, where the configuration information is used to indicate a CSI-RS configuration of UE in the target group, the target group includes at least two UEs, and CSI-RS configurations of all UEs in the target group are the same; and sending, by the base station in a first preset time-frequency resource area, the configuration information to the UE in the target group. This application resolves a problem of relatively high signaling overheads, thereby achieving an effect of reducing signaling overheads. This application is applied to configuration information transmission.

Abstract: A radio access node (RAN) and method of operation of the RAN are provided. The RAN includes a massive multiple-input-multiple-output (MIMO) antenna array. The RAN includes a processing hardware configured to carry out a communication method that includes receiving a digital data stream for transmission on a time-frequency resource. The RAN precodes the digital data stream using a digital beamforming stage to render a precoded digital downlink data stream for downlink data stream signal transmission to a user equipment. The digital beamforming stage includes a first precoding stage configured according to a long-term matrix, and a second precoding stage configured according to a short-term matrix. The RAN is further configured to generate a downlink data stream transmission signal to the user equipment in accordance with the precoded digital downlink data stream.
