Abstract: A data transmission method and apparatus are described. The method includes a receive end receiving a first parameter, where the first parameter includes a parameter of a probability distribution of a hidden variable. The hidden variable is obtained by encoding first data by using an encoder of a variational auto-encoder. The receive end determines the probability distribution based on the first parameter, and samples the probability distribution M times to obtain M pieces of sampled data, where M is a positive integer. The receive end reconstructs the first data based on the M pieces of sampled data. According to the described data transmission method and apparatus, the first parameter is transmitted, so that the receive end can support a plurality of times of sampling, thereby reducing an amount of data transmitted over an air interface, and reducing data transmission overhead.

Abstract: This application provides a method for communicating a modulation and coding scheme (MCS). A terminal device obtains a modulation order, a code rate, or a spectral efficiency, determines an index of a reference MCS from a mapping table based on the obtained modulation order, code rate, or spectral efficiency, and reports the index of the reference MCS to a network device. The mapping table includes one or more mapping relationships between an MCS index and a modulation order, a code rate, or a spectral efficiency. The terminal device may process uplink or downlink data based on the determined MCS, thereby improving data transmission reliability.
