Hybrid automatic repeat request harq-based communication method and apparatus

Abstract

This application discloses a communication method includes: obtaining a plurality of information bits in first transmission; grouping the plurality of information bits into m groups of first information bit sequences K, . . . , K; encoding the m groups of first information bit sequences to obtain a first target encoded codeword; sending the first target encoded codeword to a receive end; performing interleaving processing on n groups of first information bit sequences in the m groups of first information bit sequences in tretransmission if the first transmission fails, to obtain m groups of first bit sequences X, . . . , X; encoding the m groups of first bit sequences to obtain a second target encoded codeword; and sending the second target encoded codeword to the receive end. In this way, in a HARQ-based implementation, interleaving processing is performed on some information bit sequences in a retransmission process.
