DATA TRANSMISSION METHOD AND APPARATUS

WIPO Patent Application WO/2024/131482

A1

A data transmission method and apparatus, relating to the field of wireless communications. The method comprises: obtaining a first bit sequence and sending feedback information, wherein the length of the first bit sequence is associated with a first target code rate, the first bit sequence comprises a second bit sequence, the length of the second bit sequence is associated with a second target code rate, the first target code rate and the second target code rate are associated with a first modulation and coding scheme index, and the feedback information is used for feeding back whether the first bit sequence and the second bit sequence are transmitted correctly. Thus, an RAN node can determine, according to the feedback information, whether the second bit sequence is transmitted correctly, and then a target code rate of the next data transmission of a service corresponding to the second bit sequence is updated in time according to the transmission situation of the second bit sequence, thereby improving the data decoding success rate in the service.
