Abstract: Example uplink reference signal sending methods and apparatus are described. One example method includes sending signaling to a terminal device by an access network device. The terminal device determines a sequence type of an uplink reference signal based on the signaling. The terminal device determines transmit power of the uplink reference signal based on the sequence type of the uplink reference signal, and sends the uplink reference signal by using the transmit power of the uplink reference signal.

Abstract: Embodiments of this application provide a power headroom reporting method and apparatus. Impact of introduction of multi-beam transmission, a plurality of time-frequency resource configurations, or an uplink multi-waveform technology on a power headroom is considered, so that the power headroom is calculated and reported more accurately, to help a network side make a scheduling decision, thereby improving communication performance.

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
