Abstract: This application provides a reference signal indication method and apparatus. The method includes: transmitting, by a terminal device, a phase tracking reference signal (PTRS) to a network device based on a time domain density; and receiving, by the network device, the PTRS transmitted by the terminal device based on the time domain density, where the time domain density is a density in a discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM) waveform. Therefore, successful PTRS transmission can be ensured.

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: Embodiments of this application provide a parameter determining method, a base station, and user equipment. The parameter determining method provided in this application includes: determining, by a base station, a first subcarrier spacing corresponding to UE; and notifying, by the base station, the UE of the first subcarrier spacing. In the embodiments of this application, the UE may accurately learn of, in a multi-subcarrier-spacing system, a subcarrier spacing used for data transmission, and then perform data transmission. This can effectively ensure that the UE performs a corresponding service, thereby meeting a corresponding service requirement.

Abstract: A reference signal transmission method includes: sending, by a terminal, a first reference signal and a second reference signal; and correspondingly, receiving, by a network device, the first reference signal and the second reference signal, where the first reference signal is mapped to a plurality of symbols and is used for estimation of channel state information, the second reference signal is mapped to at least two of the plurality of symbols and is used for phase tracking, and a subcarrier to which the second reference signal is mapped on one of the at least two symbols has a same frequency-domain location as a subcarrier to which the second reference signal is mapped on the rest of the at least two symbols. With the foregoing solution, accuracy of channel state information estimation can be improved.

Abstract: Devices, methods and computer readable medium for two-part feedback information transmission in wireless communications are provided. The two-part feedback information transmission is adopted, e.g., for improved downlink multiple-input and multiple-output (MIMO) precoding in time-division duplex (TDD)-based communication systems. The feedback information transmission allows compensating for adverse effects of incomplete UL-DL reciprocity for DL MIMO precoding caused by mismatched DL and UL channel measurements. The feedback information transmission being two-part allows low overhead for the feedback information.
