    Abstract: This application relates to communicating information between communication devices. A channel coding method is disclosed. A communication device obtains an input sequence of K bits. The communication device encodes the input sequence using a low density parity check (LDPC) matrix H, to obtain an encoded sequence. The LDPC matrix H is determined according to a base matrix and a lifting factor Z. The base matrix includes m rows and n columns, m is greater than or equal to 5, and n is greater than or equal to 27. The lifting factor Z satisfies a relationship of 22*Z≥K. According to the encoding method provided in the embodiments, information bit sequences of a plurality of lengths can be encoded for transmission between the communication devices.

    Abstract: Embodiments of this application provide an information processing method and a wireless transmission device. The method includes: obtaining, by a wireless transmission device, a target modulation and coding scheme MCS level; determining, by the wireless transmission device based on a correspondence among MCS levels, modulation schemes, and transport block parameters, a target modulation scheme and a target transport block parameter that correspond to the target MCS level; and performing, by the wireless transmission device, low-density parity-check code LDPC coding or decoding on a transport block based on the target modulation scheme and the target transport block parameter. According to the foregoing technical solution, a wireless transmission device in a system in which LDPC coding is used may perform LDPC coding or decoding on a transport block.

    Abstract: This application discloses a data transmission method, a sending device, a receiving device, and a communications system. The sending device is configured to send a first transport block. The sending device obtains a coded bit segment from a first encoded code block. The first encoded code block is obtained after LDPC encoding is performed on a first code block in the first transport block based on a processing capability of the receiving device. The sending device sends the coded bit segment to the receiving device. Because the processing capability of the receiving device is considered, storage overheads of the sending device or the receiving device can be reduced, encoding or decoding complexity can be reduced, and a decoding success rate can be improved.
