Abstract: The present disclosure discloses a communication method, an apparatus, and a system. The communication method includes: receiving, by a base station, uplink data sent by a terminal device; decoding the uplink data; and sending, by the base station, feedback information of the uplink data. The feedback information is used to indicate a decoding status of the uplink data, and carries information about an identifier. The identifier includes an identity of the terminal device or an identifier of the uplink data. In this way, the terminal device is prevented from receiving incorrect feedback information during conflicting transmission.

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.
