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: This application discloses a pulse shaping method, a transmitter, a receiver, and a system. The transmitter includes an inverse Fourier transform module, a pulse shaping filter, a pulse shaping controller, and a parallel-to-serial conversion module. The pulse shaping controller is configured to: receive pulse configuration signaling, generate, based on the pulse configuration signaling, a pulse parameter corresponding to a to-be-configured pulse, and output the pulse parameter to the pulse shaping filter. The pulse shaping filter is configured to: perform subcarrier-level filtering on an output signal of the inverse Fourier transform module, perform pulse shaping processing on the output signal of the inverse Fourier transform module based on the pulse parameter, and output a processed signal in serial by using the P/S module. Different pulse parameters correspondingly represent different pulse shapes. In the foregoing solution, pulse shaping can be flexibly configured, to support different communication scenarios.
