Abstract: A communication method and a communication apparatus are provided. The method includes: a first device first checks a first bit sequence based on a cyclic redundancy check (CRC) code, to obtain a second bit sequence; then divides the second bit sequence into P bit sequences; and generates Q codewords based on the P bit sequences, and sends the Q codewords to a second device through P transport layers. P represents a quantity of transport layers of the first device, P is greater than or equal to 2, and Q is an integer greater than or equal to 2. The first device first checks the first bit sequence based on the CRC code, and then divides the second bit sequence into the P bit sequences, that is, performs code rate allocation.

Abstract: Example communication methods and apparatus are described. One example method includes generating a first signal and sending a first signal, where the first signal includes an orthogonal frequency division multiplexing (OFDM) symbol, a first-type cyclic prefix (CP), and a second-type CP. CP resources of the first-type CP include two types of CP resources: a first CP resource and a second CP resource. CP resources of the second-type CP include one type of CP resource, that is, the second CP resource. The first CP resource may be used to carry data that is different from data carried on the OFDM symbol. The second CP resource may be used to carry data that is the same as the data carried on the OFDM symbol.
