Abstract
A data transmission method, a device, and a storage medium are disclosed. The method may include sending a Modulation and Coding Scheme (MCS) index value to a second communication node; where, the MCS index value is indicative of one sets of parameters of a plurality sets of parameters in an MCS index table; and at least one set of the plurality sets of parameters in the MCS index table correspond to Regular Amplitude Phase Shift Keying (RAPSK) modulation.
