1. A wireless communication method, the method comprising:
determining a target modulation and coding scheme (MCS) index if an MCS index of data exceeds a predetermined threshold, wherein the target MCS index is less than or equal to the predetermined threshold; and
determining a time domain density of a phase tracking reference signal (PTRS) based on the target MCS index;
wherein:
the predetermined threshold is 28 or 27; and
when the predetermined threshold is 28, the MCS index of data is 29, 30, or 31; or
when the predetermined threshold is 27, the MCS index of data is 28, 29, 30, or 31; and
wherein the determining the target MCS index comprises:
using an MCS index used in an initial transmission as the target MCS index.
