Abstract: A signal processing method and device are provided. The method includes indicating a first uplink sounding reference signal resource to a terminal, wherein the first uplink sounding reference signal resource is used for uplink beam scanning; receiving a uplink sounding reference signal transmitted by the terminal by using the first uplink sounding reference signal resource; determining a target uplink sounding reference signal based on the uplink sounding reference signal transmitted by the terminal, and transmitting an identifier of the target uplink sounding reference signal to the terminal; indicating a second uplink sounding reference signal resource to the terminal, the second uplink sounding reference signal resource being used to cause the terminal to transmit an uplink sounding reference signal for channel measurement based on the identifier of the target uplink sounding reference signal and the second uplink sounding reference signal resource.

Abstract: A method for acquiring system information, a method for transmitting system information, a terminal, a network reception and transmission node and a storage medium are provided. The method for acquiring the system information includes: receiving a synchronization signal transmitted from a network reception and transmission node, and acquiring feature information of the synchronization signal, node information of the network reception and transmission node and a correspondence between the feature information and a transmitting position of the system information; acquiring the transmitting position of the system information corresponding to the node information based on the feature information and the correspondence: and receiving, at the transmitting position of the system information, the system information transmitted from the network reception and transmission node.

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: 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.
