Abstract: Embodiments of this application provide a communication method and an apparatus. A correspondence between a plurality of MCS indexes and a plurality of modulation schemes is provided to achieve flexible selection of a modulation scheme. In the correspondence, at least one MCS index of the plurality of MCS indexes corresponds to a set modulation schemes which comprises π/2 binary phase shift keying (π/2-BPSK) modulation and quadrature phase shift keying (QPSK) modulation. A first communication device receives a target modulation and coding scheme (MCS) index from a second communication device, determines a target modulation scheme corresponding to the target index number based on the correspondence, and performs communication with the second communication device based on the target modulation scheme.

Abstract: This application discloses a signal transmission method and apparatus, to implement signal transmission by using a multi-stream DFT-s-OFDM waveform. The method includes: precoding N streams of signals based on a first codebook before sending, to obtain N1 precoded signals, where a quantity of non-zero elements in each row of the first codebook is 1, the first codebook causes a phase difference between two of the N streams of signals, and N and N1 are integers greater than 1; and sending the N1 precoded signals. A transmitting end introduces a phase offset between two transmit antenna ports in a precoding process, so that equivalent inter-stream interference is optimal after channel equalization is performed at a receiving end, to improve demodulation performance of the receiving end.
