    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: Embodiments of this application provide a method for encoding data in a wireless communication network. A communication device obtains an information bit sequence of a bit length K and a code length M. When M is greater than or equal to a first threshold and K is greater than or equal to a second threshold, the device divides the information bit sequence into p subsequences that are of an equal length K1. Then the device encodes each of the p subsequence to obtain p encoded subsequences. The device rate-matches each of the p encoded subsequences to obtain p rate matched subsequences, concatenates the p rate matched subsequences to obtain the output sequence of the code length M, then outputs the output sequence.

    Abstract: A method for transmitting data streams in a multiple input multiple output (MIMO) system is provided, where each data stream is mapped to multiple layers in an MIMO channel space for transmission, and the method includes: performing inter-layer interleaving for N data streams to obtain N interleaved data streams; mapping the N interleaved data streams respectively to N layers in the MIMO channel space, and transmitting the N interleaved data streams that are mapped to the N layers. By using the method of the present invention, a combined CQI can be used in a better way to improve MIMO transmission performance. Further, an impact of inter-layer interference is canceled by using an interference cancellation technology (for example, an SIC technology) based on the inter-layer interleaving.
