Abstract: In a data processing method, a transmit end may send, to a receive end, coding information of N layers of first bit sequences and second information that does not include some or all bits in the N layers of first bit sequences, and the receive end may process the coding information and the second information, to obtain the N layers of first bit sequences. Because the transmit end sends the coding information to the receive end, information sent by the transmit end may not include some or all bits in the N layers of first bit sequences.
