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 reference signal determining method and an apparatus. The method includes a first device determines a first reference signal sequence in a reference signal sequence set. The first device maps the first reference signal sequence to a first symbol sequence, and sends a first reference signal corresponding to the first reference signal sequence to a second device based on the first symbol sequence. The first reference signal sequence is used by the second device to estimate impact of phase noise on a received signal, and the impact of the phase noise on the received signal includes at least one of inter-subcarrier interference, a common phase error, and the phase noise. The reference signal sequence set includes at least a first-type reference signal sequence. A time-domain amplitude variance and a frequency-domain amplitude variance of the first-type reference signal sequence each meet a preset threshold.

Abstract: This application discloses a signal transmission method, including: obtaining, by a terminal device, to-be-transmitted data, uplink control information, and a demodulation reference signal; mapping the to-be-transmitted data, the uplink control information, and the demodulation reference signal to generate multiplexed symbols. The multiplexed symbols include DFT-s-OFDM symbols or OFDM symbols. N first multiplexed symbols are located on one side or two sides of a second multiplexed symbol. A location relationship between each of the N first multiplexed symbols and the second multiplexed symbol satisfies a mapping condition. N is an integer greater than or equal to 1. The first multiplexed symbol is a multiplexed symbol to which the uplink control information is mapped, and the second multiplexed symbol is a multiplexed symbol to which the demodulation reference signal is mapped.
