Document Type and Number:

WIPO Patent Application WO/2018/082672

Kind Code:

A1

Abstract:

Provided in embodiments of the present invention is an uplink reference signal transmission method. A user equipment receives first configuration information of a first uplink sounding reference signal and second configuration information of a second uplink sounding reference signal from a radio network device, the first configuration information being used for configuring a time-frequency resource for the first uplink sounding reference signal, the second configuration information being used for configuring a time-frequency resource for the second uplink sounding reference signal, the first uplink sounding reference signal being a zero-power uplink sounding reference signal, and the second uplink sounding reference signal being a nonzero-power uplink sounding reference signal; and the user equipment transmits the second uplink sounding reference signal on a time-frequency resource not for the first uplink sounding reference signal of the time-frequency resource for the second uplink sounding reference signal on the basis of the first configuration information and of the second configuration information.
