1. A reference signal sending method, comprising:
receiving configuration information of a first reference signal from a network device; and
sending, based on the configuration information, an uplink signal to the network device in each of at least two time units, wherein each uplink signal comprises uplink data and the first reference signal, the at least two time units comprise a first time unit and a second time unit, the first time unit is adjacent to and located before the second time unit, the first reference signal is carried on the earliest N symbols in a time domain of symbols that are in the second time unit and on which the uplink signal is located, the first reference signal is carried on the latest M symbols in the time domain of symbols that are in the first time unit and on which the uplink signal is located, and N and M are integers greater than or equal to 1;
wherein a subcarrier that carries the first reference signal and that is in the latest M symbols in the time domain of the first time unit is the same as a subcarrier that carries the first reference signal and that is in the earliest N symbols in the time domain of the second time unit.
