Abstract
A method may include: dividing, by a sending device into k code blocks CBs, a TB into which a cyclic redundancy check bit is loaded, then separately performing channel coding on the k CBs, to obtain a bit sequence Sj, where j=1, 2, . . . , and k, and a set S={S1, S2, . . . , Sk}, and mapping, by the sending device, some or all bit sequences in all elements in S to transmission resources in N basic transmission time units, where some or all bit sequences in the Sj are mapped to transmission resources in Mj basic transmission time units, and a last bit in the Sj mapped to an mth basic transmission time unit in the Mj basic transmission time units and a first bit in the Sj mapped to an (m+1)th basic transmission time unit are contiguous in the Sj.
