Abstract: This application discloses an information processing method. A communication device obtains an input sequence. The input sequence has a quantity B of bits. The communication devices transforms the input sequence into one or more code blocks. The communication device encodes each of the code blocks, to obtain one or more encoded code blocks. Each of the code blocks has a code block length less than or equal to a maximum code block length. Each of the code blocks includes a segment of the input sequence, one or more cyclic redundancy check (CRC) bits corresponding to the segment of the input sequence, and one or more filler bits. The encoded code blocks can meet various channel coding requirements.

Abstract: Embodiments of this application relate to communication technologies and provide a method for transmitting or retransmitting data in a transport block. The transport block includes one or more code block groups, and each code block group includes one or more code blocks. A data processing device determines a code block group in the transport block that needs to be transmitted. Each code block in the code block group is processed by the data processing device to obtain a bit sequence. The data processing device transmits one or more bit sequences obtained by processing one or more code blocks in the code block group. The method and the apparatus provided in this application help reduce waste of air interface resources.

Abstract: This application discloses an information processing method, an apparatus, a communication device, and a communication system. The communication device is configured to determine a redundancy version transmission sequence, where the redundancy version transmission sequence is used to indicate a sending sequence of a plurality of redundancy versions; determine a transmission number; and obtain a redundancy version from a buffer sequence based on the redundancy version transmission sequence and the transmission number and send the redundancy version. The communication device may be applied to a communication system supporting a plurality of redundancy version transmission sequences, for example, a 5th generation (5G) communication system. Because the redundancy version transmission sequence is determined before data transmission, communication efficiency is improved, and HARQ performance is improved.

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.
