Abstract: This application provides a reference signal transmission method and an apparatus, used in a multipoint coordination transmission scenario. In one example method, a frequency domain resource that carries a target reference signal in a frequency domain resource or a time domain resource that is associated with each QCL assumption may be separately determined, and then the target reference signal carried on the frequency domain resource that is associated with the QCL assumption is separately received by using the corresponding QCL assumption.

Abstract: This disclosure provides example wireless communication methods and communication apparatuses. One example method includes that a network device sends indication information of m first symbol groups used for repeated transmission of a first transport block (TB) to a terminal. The terminal and the network device determine, according to a same rule, a quasi co-location (QCL) assumption corresponding to each of second symbol groups actually used when the first TB is sent or received.

Abstract: A terminal device may receive precoding indicator information, where the precoding indicator information includes K first indicators and one second indicator. The terminal device determines K first precoding matrices based on the K first indicators, and determines a second precoding matrix based on the second indicator, where K is a positive integer. The terminal device precodes, by using the K first precoding matrices, data sent in K first frequency bands, to obtain precoded first data, and precodes, by using the second precoding matrix, data sent in a second frequency band, to obtain precoded second data. The K first frequency bands are located in some frequency bands in a physical uplink shared channel (PUSCH) scheduling frequency band. The second frequency band is a frequency band in the PUSCH scheduling frequency band other than the K first frequency bands.

Abstract: Example data transmission methods and apparatus are described. One example method includes determining an actual transmit power for first uplink data by a terminal device based on a determined channel transmit power and a transmission parameter. The actual transmit power is less than or equal to the channel transmit power, and the transmission parameter includes one or more of parameters that can be used to indicate a location of the terminal device. The terminal device sends the first uplink data at the actual transmit power. Therefore, the terminal device may determine the actual transmit power for the uplink data based on the channel transmit power and various transmission parameters that can indicate whether the terminal device is located at a cell edge, so that the actual transmit power for the uplink data can be flexibly adjusted.
