Abstract: A channel encoding method and apparatus. The method includes: obtaining A to-be-encoded information bits; mapping the A to-be-encoded information bits and L CRC bits to a first bit sequence based on an interleaving sequence, where the L CRC bits are obtained based on the A to-be-encoded information bits and a CRC polynomial, the interleaving sequence is obtained from a prestored interleaving sequence table or is obtained based on a maximum-length interleaving sequence, A+L is less than or equal to Kmax, and Kmax is a length of the maximum-length interleaving sequence; and encoding the first bit sequence.

Abstract: A coding scheme determining method and apparatus are provided. In various embodiments, a base station device sends, to a terminal device, higher layer control signaling, physical layer control signaling, or a synchronization signal that carries coding scheme indication information. In some embodiments, a terminal device sends, to a base station device, a capability information report message that carries coding scheme indication information, so that the base station device or the terminal device can clearly and flexibly indicate a coding scheme. At least one information block size IBS greater than or equal to a preset first specified value X is determined, and an IBS is selected from the at least one IBS to code an information block of bits or a code block of the information block of bits. X and a coding scheme are determined by a scenario, information type, and/or service type.

Abstract: A data transmission method and apparatus, and relates to the communication field. In the method, after obtaining a path parameter of each of at least one communication path between a first device and a second device, the first device may demodulate first data based on a pilot and the path parameter of each communication path. In other words, when demodulating the first data, the first device may refer to not only the pilot but also the path parameter of each communication path. The path parameter of each communication path can assist in demodulating the first data. When the path parameter of each communication path assists in demodulating the first data, there may be no need for too many pilots. Therefore, a resource occupied by the pilot can be reduced.
