Abstract: This application discloses a data reporting method, a data receiving method, and related apparatuses. 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.

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 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: An information transmission method and apparatus are provided. The method includes: determining a time domain density of a phase tracking reference signal (PTRS); determining a frequency domain density of the PTRS based on an available bandwidth, a scheduled resource block (RB) or an available RB; mapping the PTRS to one or more orthogonal frequency division multiplexing (OFDM) symbols based on the time domain density and the frequency domain density; and sending a signal that includes the OFDM symbol to which the PTRS is mapped. According to this application, a quantity of PTRSs can be prevented from jumping when a value of scheduled bandwidth is close to a threshold, both accuracy of common phase error estimation and spectral efficiency are taken into consideration, and the PTRSs can be uniformly mapped in the scheduled or available bandwidth, thereby properly configuring the PTRSs.
