Abstract: A CSI-RS measurement feedback method and device are provided to optimize analog and digital precoding. A network device sends S CSI-RSs to a terminal device. Each CSI-RS corresponds to one antenna port number. The terminal device sends M antenna port numbers that correspond to M CSI-RSs and sends a PMI that corresponds to a channel matrix H or the quantization result of a channel matrix H to the network device. The terminal device selects the M antenna port numbers that correspond to the M CSI-RSs from the S antenna port numbers that correspond to the S CSI-RSs, and feeds back the M antenna port numbers to the network device.

Abstract: In a signal transmission method, a user equipment receives a first signal from a wireless network device; and the user equipment determines spatial information of a to-be-transmitted second signal based on the first signal, and transmits the to-be-transmitted second signal by using the spatial information. An uplink transmit beam is determined by using related information of a downlink receive beam, so that the UE can efficiently determine spatial information of an uplink signal to be transmitted by the UE.

Abstract: An uplink reference signal transmission method is disclosed. User equipment receives first configuration information of a first uplink measurement reference signal and second configuration information of a second uplink measurement reference signal from a wireless network device. The first configuration information is used to configure a time-frequency resource of the first uplink measurement reference signal, and the second configuration information is used to configure a time-frequency resource of the second uplink measurement reference signal. The first uplink measurement reference signal is a zero-power uplink measurement reference signal, and the second uplink measurement reference signal is a non-zero-power uplink measurement reference signal. The user equipment sends, based on the first configuration information and the second configuration information, the second uplink measurement reference signal on a time-frequency resource, other than the time-frequency resource of the first uplink measurement reference signal, in the time-frequency resource of the second uplink measurement reference signal.
