Abstract: The application discloses a reference signal transmission method to improve reference signal transmission flexibility. A target time-frequency resource occupied by a reference signal of at least one antenna port in at least one transmission unit is determined. Each of the at least one transmission unit includes a first part. The target time-frequency resource is located on at least one symbol in the first part, and in the reference signal of the at least one antenna port, different reference signals are located in different transmission units in the at least one transmission unit. The reference signal of the at least one antenna port is sent to a receive-end device by using the target time-frequency resource in the at least one transmission unit.

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.
