Abstract: Disclosed are a beam management method, a network device and a terminal. The method comprises: the network device allocates an SRS source to a terminal; and the network device transmits indication information to the terminal, wherein the indication information is used for indicating the terminal to select a transmission beam used for transmitting SRS on the SRS source, so as to manage the transmission beam of the terminal and a receiving beam of a base station more flexibly and effectively, to achieve scanning of the transmission beam of the terminal and/or the receiving beam of the base station.

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: Disclosed are a channel status information (CSI) feedback and control method and device. The method comprises: a terminal receives trigger signaling sent by a base station, the trigger signaling being used for instructing the terminal to report CSI obtained within a specified measurement window; and the terminal reports the CSI that is measured by the terminal within the specified measurement window to the base station. Because a terminal reports only CSI that is measured by the terminal within a specified measurement window, the frequency of feeding back CSI by the terminal is reduced, and CSI feedback overheads are also reduced.

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.

Abstract: Disclosed are a channel state information feedback and acquisition method and device. The application comprises: acquiring, by a terminal, a first-dimension downlink reference signal resource, S second-dimension downlink reference signal resources and a first corresponding relationship of the above configured by a network device; measuring, by the terminal and according to the first-dimension downlink reference signal resource, a first-dimension downlink reference signal, and selecting, by the terminal and according to the measured first-dimension PMI and the first corresponding relationship, a resource for measuring a second-dimension downlink reference signal, measuring, according to the resource, the second-dimension downlink reference signal, and feeding back channel state information, wherein the second-dimension reference signal is transmitted after forming a first-dimension beamforming weight. The present application enables acquisition of channel state information between a network device and a terminal, and adjustment of the first-dimension beamforming weight for forming the second-dimension reference signal according to the PMI fed back by the first-dimension.

Abstract: The present disclosure provides a CSI feedback method, a CSI feedback device and a CSI feedback system. The CSI feedback method includes steps of: configuring, by a network side device, a first downlink channel measurement pilot for a UE; and receiving, by the network side device, first PMI information fed back by the UE. The first PMI information is acquired by the UE based on measurement of the first downlink channel measurement pilot and second PMI information. A dimension represented by the first PMI information is different from a dimension represented by the second PMI information.
