1. A method, comprising:obtaining to-be-transmitted K bits;

mapping the K bits to F resource units according to a codebook and a value of the K bits, so as to obtain a codeword CK that is to be transmitted using the F resource units, wherein the codebook comprises S codewords in a one-to-one mapping relationship with S different values of the K bits, S is less than or equal to 2K, each codeword in the S codewords is a complex number vector that comprises F complex numbers, a difference between the ith value and the jth value of the K bits is that a value of only one bit is different, a codeword that is comprised in the codebook and in a mapping relationship with the ith value is a codeword Ci, and a codeword that is comprised in the codebook and in a mapping relationship with the jth value is a codeword Cj, wherein the codeword Ci, does not comprise a complex number Zj1 and a complex number Zj2 that are comprised in the codeword Cj, K, F, and S are integers greater than 1, i is not equal to j, and i and j are positive integers less than or equal to S; and

sending the codeword CK using the F resource units.
