    Abstract: The embodiments of the present disclosure provide an information transmission method, a network device, a terminal device and a storage medium, which can improve the demodulation performance of a terminal and/or reduce pilot overheads in a high-speed movement scenario. Said method comprises: transmitting, to a terminal device, quasi-co-location (QCL) configuration information of a downlink signal, the QCL configuration information indicating at least two reference signals and a QCL type corresponding to the reference signals, a first reference signal in the reference signals being used by the terminal device to determine a Doppler characteristic of the downlink signal, and a second reference signal in the reference signals being used by the terminal device to determine a time delay characteristic of the downlink signal, there being one or more first reference signals, and there being one or more second reference signals; and transmitting the downlink signal to the terminal device.

    Abstract: The present disclosure relates to the technical field of communications, and in particular to a method and apparatus for acquiring uplink channel state information, which are used for acquiring a transmission path with a relatively low delay. The method comprises: a network side device generating SRS resource configuration information on the basis of a preset bandwidth parameter, a frequency domain density parameter and a time domain parameter, and receiving at least one SRS returned by a terminal on the basis of the SRS resource configuration information; and then the network side device measuring, on the basis of the at least one SRS, an uplink channel used by the terminal, and determining corresponding uplink channel state information. In this way, SRS resource configuration information is generated by means of a preset bandwidth parameter and frequency domain density parameter, such that a bandwidth configuration of an SRS resource can be increased, and a frequency domain density of the SRS resource can be reduced, thereby improving a signal to interference plus noise ratio of each SRSRE; and a network side device can capture transmission paths with different time delays, thereby designing a port selection codebook with a higher precision.
