Title: WIRELESS COMMUNICATION METHOD AND APPARATUS
Abstract:
Disclosed in the embodiment of the present application are a wireless communication method and apparatus. The method comprises: if a current modulation and coding scheme MCS exceeds a predetermined threshold, determining a target MCS, the target MCS being an MCS less than or equal to the predetermined threshold; mapping a phase tracking reference signal PTRS to one or more symbols or subcarriers according to the target MCS; and transmitting symbol or subcarrier to which the PTRS is mapped to a terminal device. It can be seen that, by implementing the embodiment of the present application, when the current MCS exceeds the predetermined threshold, a target MCS that is less than or equal to the predetermined threshold can be determined, so that the density of PTRS on time-frequency resources can be flexibly determined according to the target MCS and the associative relationship between the MCS threshold and the PTRS time domain density, which facilitates reduction of the resource overhead of PTRS.
