摘要

A method and device for transmitting data and a method and device for receiving data are provided. The method for transmitting data comprises: processing the data in at least five processes of cyclic redundancy check attachment, channel coding, rate matching, modulation and resource element mapping to generate a signal; and transmitting the signal in a plurality of subframes with a repetition level i, wherein the repetition level i is selected from a repetition level set including at least two different repetition levels, and for repetition level i, the data are transmitted in Ri subframes, and for different repetition levels, values of Ri are different, and wherein the data are processed by the five processes or by the five processes and at least one additional process to generate different signals to be transmitted according to different repetition levels.
