Abstract: A communication method and a communication apparatus are provided. The method includes: A first device receives first information, determines a target TR pattern based on the first information, and sends information or demodulates received information based on the target TR pattern, where the target TR pattern is a sub-pattern of a longest TR pattern, and the longest TR pattern includes a set of sub-carriers used as reserved tones. The longest TR pattern may include a plurality of TR sub-patterns of different lengths. For example, a first TR pattern of a first length is a sub-pattern of the longest TR pattern, and a second TR pattern of a second length is also a subset of the longest TR pattern. The TR sub-patterns of different lengths may correspond to different carrier bandwidths or quantities of RBs.

Abstract: A communication method and apparatus are provided. The method includes: A terminal device receives a first synchronization broadcast block (SSB) from a network device, where the first SSB indicates that a current network is in a coverage enhancement mode; then, the terminal device determines a target resource of first system information based on the first SSB; and finally, the terminal device receives the first system information from the network device based on the target resource. In the method, transmission of a plurality of repeated SSBs can be supported in the network coverage enhancement mode, and a quantity of transmitted system information blocks 1 (SIB1s) can be reduced, to reduce system overheads.

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 polar coding method, a polar decoding method, and an apparatus. A transmit end obtains K to-be-coded bits and an index set including K polar channels, where a value set of K1 indexes in the set of the K indexes or a value set of K2 indexes in the set of the K indexes is determined based on a value set of K2 of the K to-be-coded bits, and the value set of the K1 indexes and the value set of the K2 indexes are complementary sets of each other; and performs polar coding on K1 to-be-coded bits. In comparison with a conventional polar coding method and a conventional polar decoding method, the polar coding method and the polar decoding method provided in this application can achieve an effect of reducing a bit rate. A simulation result indicates that the method has better performance.
