Abstract: A method for data transmission, a base station and a terminal are provided. The method for data transmission includes: configuring the number of bits occupied by downlink control information (DCI) used to indicate physical downlink shared channel (PDSCH) scheduling on each of all carriers corresponding to a to-be-scheduled terminal to be N, where N is a maximum number of bits occupied by the DCI that is used to indicate the PDSCH scheduling on a carrier configured with an aperiodic channel state information reference signal (CSI-RS); and constructing scheduling information for indicating the PDSCH scheduling based on the configured DCI, and transmitting the scheduling information to the to-be-scheduled terminal.

Abstract: The present disclosure provides a reference signal transmission method, a transmitter and a receiver. The reference signal transmission method includes: precoding, by a transmitter, a data stream for user data through a second precoding matrix so as to acquire D virtual data streams; precoding, by the transmitter, the D virtual data streams through a first precoding matrix, and transmitting the D precoded virtual data streams to a receiver via T antenna groups, each antenna group including one or more antenna units or antenna ports having a same phase noise; transmitting, by the transmitter, D demodulation reference signals to the receiver; and transmitting, by the transmitter, M phase-tracking reference signals to the receiver, the M phase-tracking reference signals being adopted to track phase changes in the T antenna groups caused by one or more phase noise sources.

Abstract: The embodiments of the present disclosure provide a method and a device for constraining a codebook subset. The method includes steps of: determining codebook subset constraint parameters for all or parts of matrix sets for constructing a codebook respectively, each codebook subset constraint parameter indicating an available matrix in a corresponding matrix set; and transmitting the determined codebook subset constraint parameters to a UE. The number of the matrices in each matrix set for constructing the codebook is far less than the number of precoding matrices in the codebook.
