    Abstract: This application provides a signal communications method and a signal communications method apparatus. The method includes: receiving a first reference signal; receiving a DMRS; determining a reception parameter of a first signal according to channel characteristics of the first reference signal and/or performing a channel estimation for the first signal according to the channel characteristics of the first reference signal; wherein each layer of the first signal is associated with N DMRS ports corresponding to the DMRS, the N DMRS ports associated with a layer of the first signal are in a QCL relationship with N first reference signals, respectively.

    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 provides a signal transmission method and apparatus, a terminal and a base station. The method includes: obtaining indication information; determining a transmission mode of PUSCH according to the indication information; where the transmission mode includes a first transmission mode and/or a second transmission mode, and the first transmission mode and the second transmission mode have different first characteristics; according to the transmission mode, determining a first parameter and/or a second parameter corresponding to the transmission mode; where the first transmission mode is corresponding to the first parameter, and the second transmission mode is corresponding to the second parameter; and transmitting the PUSCH according to the first parameter and/or the second parameter; where the first parameter is different from the second parameter.
