Abstract: An embodiment of the present invention provides a reference signal configuration method. The method includes: obtaining, by the base station, a first time-domain location of a reference signal of a first cell, and mapping the reference signal of the first cell to one or more resource elements based on the first time-domain location, where there is an offset between the first time-domain location and a second time-domain location of a reference signal of a second cell, the first cell is a cell in which the base station is located, and a service area of the second cell is different from that of the first cell; and sending, by the base station, the reference signal of the first cell. According to the embodiment, mutual interference of reference signal transmission in cells can be avoided, and signal transmission efficiency and signal transmission quality can be improved.

Abstract: A communication method is provided, including: determining, by a first device, a relative power ratio between a phase tracking reference signal (PTRS) and a data channel; determining, by the first device, a transmit power of the PTRS based on the relative power ratio of the PTRS to the data channel; and sending, by the first device, the PTRS to a second device by using the transmit power of the PTRS.

Abstract: The present disclosure relates to example uplink measurement signal indication methods and apparatuses. One example method includes receiving, by a terminal device, signaling sent by a network device, where the signaling carries indication information that indicates a transmit beam for sending an uplink measurement signal by the terminal device, and sending, by the terminal device, the uplink measurement signal to the network device based on the indication information by using the transmit beam.
