Abstract: The present disclosure discloses an uplink signal sending method and receiving method, a terminal, and a base station. The method includes: receiving, by a terminal, downlink signaling delivered by a base station, and determining, based on the downlink signaling, a waveform used by the terminal; determining, by the terminal based on a correspondence between a waveform and a power difference, a power difference corresponding to a target time-frequency resource; determining, based on the determined power difference, an uplink transmit power of an uplink signal that is mapped on the target time-frequency resource, and sending the uplink signal by using the power. The target time-frequency resource refers to an OFDM symbol multiplexed by an RS and a channel, or may be an RE that is used for mapping a channel and that is in an OFDM symbol multiplexed by an RS and a channel. In embodiments, a transmit power of the uplink signal on the target time-frequency resource is reduced to reduce the OFDM symbol multiplexed by an RS and a channel, so that a power-limited terminal can also normally send data, thereby optimizing use of a transmit power of the power-limited terminal
