Original Abstract Submitted

a signal transmission method and a communication apparatus are described. the method may include: mapping a reference signal to a target location in a discrete fourier transform-spread-orthogonal frequency division multiplexing dft-s-ofdm symbol, where the target location is determined based on a pattern parameter of the reference signal and a location parameter of a data block, and the location parameter of the data block is used to determine a location of the data block in the dft-s-ofdm symbol; and sending the dft-s-ofdm symbol. not only the pattern parameter of the reference signal is considered, but also the location parameter of the data block is considered, so that overall location distribution of the reference signal can be more proper, phase noise estimation performance and channel estimation performance are improved, and demodulation performance is improved.
