Abstract

A time-frequency diversity copying method and system, and a storage medium. The method comprises: acquiring original data to be transmitted; determining the number of interleavers according to the number of times of copying in an acquired carrier mapping table index; determining parameters for performing time-frequency diversity copying on the original data based on the carrier mapping table index and the determined number of interleavers; and performing time-frequency diversity copying on the original data based on the number of times of copying and the time-frequency diversity copy parameters.
