Abstract: This application provides a signal transmission method and an apparatus, to reduce an envelope ripple of a transmission signal. The method includes: A base station obtains a first bit sequence and maps the first bit sequence to a first modulation symbol sequence, where a value of each modulation symbol in the first modulation symbol sequence belongs to a first constellation point set, the first constellation point set includes K modulation symbols, and each of the K modulation symbols has a different amplitude. The base station sequentially performs a DFT, weighting, and an IFFT on each modulation symbol in the first modulation symbol sequence to obtain a first signal. Based on the foregoing solution, an envelope ripple of the signal generated by the base station in time domain is small. This facilitates demodulation of the transmission signal by a terminal.

Abstract: A signal transmission method and an apparatus are provided, to resolve a problem, in a conventional technology, that transmission performance is poor when a signal is transmitted in a DFT-s-OFDM waveform. A transmitting end maps a plurality of modulation symbols to a plurality of layers, performs discrete Fourier transform (DFT) on a modulation symbol at a part of the layers to obtain a first symbol, and performs discrete Fourier transform DFT and phase offset on a modulation symbol at a remaining part of the layers to obtain a second symbol. Phase offset is performed on a symbol at a part of layers, so that a PAPR can be reduced.
