    Abstract: A data transmission method, a data sending device, and a data receiving device are provided. The method includes: encoding, by a data sending device, information data by using a low-density parity-check (LDPC) code matrix, to obtain a bit sequence, where the bit sequence includes a first bit sequence, and the first bit sequence includes at least one information bit in the bit sequence; interleaving, the first bit sequence to obtain a first interleaved bit sequence; performing, modulation based on the first interleaved bit sequence to obtain a sending signal, and sending the sending signal. The method also includes: demodulating, by a data receiving device, a receiving signal to obtain a soft value sequence; and de-interleaving, the soft value sequence, to obtain a soft value sequence of a first bit sequence. This can improve a capability of an LDPC code resisting burst interference.

    Abstract: This application relates to the field of wireless communications technologies, and in particular, to a data processing method, apparatus, and system. This application provides a data processing method. A data sending device modulates a to-be-transmitted bit sequence, splits a real part and an imaginary part of a complex-valued symbol that is obtained through the modulation into two symbols to form a symbol sequence, performs phase rotation of symbols in the symbol sequence, and performs sending by using a single carrier frequency division multiple access (SC-FDMA) symbol. This application is intended to reduce a peak-to-average power ratio (PAPR) of a transmit signal of an orthogonal frequency division multiplexing (OFDM) system by splitting a real part and an imaginary part of a to-be-transmitted signal, and improve link quality of an entire transmission system.

    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.
