Abstract: Embodiments of the present invention disclose a reference signal sending/receiving method, a terminal device, and a network device. The terminal device determines transmit power of a reference signal of the terminal device, where the transmit power is related to a quantity of unavailable time-frequency resources in a transmission unit in which the reference signal is located; and transmits the reference signal based on the transmit power. After receiving the reference signal from the terminal device, the network device parses the reference signal based on the transmit power. The terminal device relates the transmit power of the reference signal of the terminal device to the quantity of unavailable time-frequency resources in the transmission unit in which the reference signal is located, thereby improving the transmit power of the reference signal of the terminal device in uplink MU-MIMO, and improving communication performance of the terminal device with a low signal-to-noise ratio.

Abstract: A method for indicating channel state information CSI measurement and a communication apparatus. A network device indicates, to a terminal device by using first indication information, one or more frequency domain units in a downlink reference signal resource that are used by the terminal device to obtain CSI. The terminal device determines, based on the first indication information, which frequency domain units in the downlink reference signal resource are used to obtain the CSI, and perform measurement in the frequency domain unit to obtain the CSI. The network device flexibly configures CSI measurement based on a system status, to control obtaining of the CSI. This helps the terminal device obtain the CSI more pertinently based on the indication in different cases.

Abstract: The disclosure provides channel measurement methods and communications apparatuses. One example method includes a terminal device that generates first indication information, and sends the first indication information to a network device. The first indication information indicates one or more component characteristics of a complete time-varying characteristic of a channel and a weighting coefficient of each component characteristic. The complete time-varying characteristic of the channel corresponds to a local time-varying characteristic of the channel. The local time-varying characteristic may be determined by the terminal device based on reference signals received for a plurality of times, and the complete time-varying characteristic may be determined based on the local time-varying characteristic.
