Abstract: Embodiments of this application provide a communications method and apparatus. The method includes: obtaining an input sequence of rate matching, wherein the input sequence is a retransmission sequence corresponding to a transport block, the input sequence comprises M code block groups, a value of M is less than a quantity of code block groups obtained after the transport block is segmented, and the M code block groups comprise Ct code blocks; and performing rate matching on the Ct code blocks, wherein a length of an output sequence of rate matching of each of the Ct code blocks satisfies the following conditions: when j≤Ct−γ−1, E=NL·Qm·└G′/Ct┘; when j>Ct−γ−1, E=NL·Qm·┌G′/Ct┐. The method may be applicable to a system in which transmission is performed based on a code block group, and resources are fully used as many as possible, thereby improving performance.

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: A method and an apparatus for speech signal processing are provided. The method includes: receiving an encoded speech signal sent by a user equipment, where the encoded speech signal includes a first substream, a second substream, and a third substream, and the first substream is attached with a cyclic redundancy check (CRC); performing decoding processing on the first substream, the second substream, and the third substream by adopting a decoding algorithm, where a decoding algorithm that is based on an auxiliary decision of the CRC is adopted to perform decoding processing on the first substream; and sending decoding results of the first substream, the second substream, and the third substream to a base station controller, where the decoding result of the first substream includes a decoded bit stream and a CRC result. Decoding performance of the first substream is improved, and users' higher requirements for the speech quality are met.
