Abstract: A communication method includes: determining, by a first device, a phase tracking reference signal (PTRS) pattern, where the PTRS pattern includes one or more PTRS chunks, and each PTRS chunk includes one or more PTRS samples; and mapping, by the first device, a PTRS to one or more symbols, and sending the one or more symbols to a second device.

Abstract: A wireless communication method includes: sending first indication information to a network device, wherein the first indication information is used to indicate at least one of a modulation and coding scheme threshold that corresponds to a pattern of a phase tracking reference signal and recommended by a terminal device, a scheduled resource block quantity threshold that corresponds to the pattern of the phase tracking reference signal and recommended by the terminal device, and a factor of impact of phase noise of the terminal device on a signal received by the terminal device; and receiving the phase tracking reference signal sent by the network device.

Abstract: An information transmission method related to the field of communications technologies includes: generating an orthogonal frequency division multiplexing (OFDM) symbol, where the OFDM symbol includes a pi/2-BPSK modulated data signal and a pi/2-binary phase shift keying (BPSK) modulated phase tracking reference signal (PTRS); and sending the OFDM symbol. This method may be applied to an uplink single carrier transmission scenario or a downlink single carrier transmission scenario.

Abstract: Embodiments of this application disclose a wireless communication method and an apparatus. The method includes: determining a target MCS if a current MCS exceeds a predetermined threshold, where the target MCS is an MCS less than or equal to the predetermined threshold; mapping a PTRS to one or more symbols based on the target MCS; and sending, to a terminal device, the symbol to which the PTRS is mapped. through implementation of the embodiments of this application, when the current MCS exceeds the predetermined threshold, the target MCS that is less than or equal to the predetermined threshold may be determined, so that a density of a PTRS on a time-frequency resource can be flexibly determined based on the target MCS and an association relationship between an MCS threshold and a time domain density of a PTRS, thereby helping reduce resource overheads of the PTRS.

Abstract: This application discloses a data reporting method, a data receiving method, and a related apparatus. In this application, a terminal device reports, to a network device, one group of information used to indicate scheduling bandwidth thresholds and/or scheduling MCS thresholds. Compared with directly reporting thresholds, in this application, fewer bits can be occupied, thereby reducing overheads.
