Abstract: This application discloses example data encoding methods, data decoding methods, and communication apparatuses. One example data encoding method includes generating M encoding units and distributing the M encoding units to N transmission channels. The M encoding units are obtained by encoding L frames. The M encoding units include at least one first-type unit. A first-type unit of the at least one first-type unit includes a first identifier. The first identifier indicates a start location that is in the first-type unit and that is of a frame header of a first frame in the L frames. M, N, and L are integers greater than or equal to 1.
