Abstract: Embodiments provide a method for transmitting a reference signal between a base station and a terminal. In this method, a parameter is determined by a terminal based on frequency domain location information of a frequency domain resource unit. The parameter is used to determine a sequence of the reference signal, and the reference signal is carried on the frequency domain resource unit. The reference signal can be sent to the base station by the terminal. In some embodiments, the reference signal sent by the base station can be received by the terminal. According to this method, a peak-to-average power ratio when a single terminal sends data to a base station can be reduced, and communication interference between different cells can be canceled or reduced as much as possible.

Abstract: This application discloses a reference signal configuration method and apparatus. Before a network device sends reference signals aperiodically, the network device sends configuration information to a terminal device, where the configuration information is used to indicate a timeslot offset of one or more reference signal resource sets. Therefore, the network device can flexibly send reference signals in different timeslots, thereby reducing a quantity of times of reference signal triggering and measurement result reporting, and improving efficiency of a communications system.

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.
