    Abstract: Embodiments of this application provide a coding scheme indication method and device. The method includes: obtaining, by a first device, a coding scheme indication, where the coding scheme indication is used to indicate a coding scheme of first data and/or a coding scheme of second data, the first data is data sent by the first device to a second device, the coding scheme of the first data is a polar coding scheme or a low-density parity-check LDPC coding scheme, the second data is data sent by the second device to the first device, and the coding scheme of the second data is a polar coding scheme or an LDPC coding scheme; and sending, by the first device, the coding scheme indication to the second device.

    Abstract: The application provides manner for communicating channel state information (CSI) in a communication network. A preset length is used for equalizing lengths of CSI to be reported. The preset length is determined based on a quantity of CSI-reference signal (RS) ports. A communication device determines whether a total length of one or more indication information items to be included in the CSI is less than the preset length. If the total length of the one or more indication information items to be included in the CSI is less than the preset length, the communication device adds one or more padding bits, to obtain a CSI bit sequence including the one or more indication information items and the one or more padding bits. A total length of the CSI bit sequence is consistent with the preset length. The communication device then outputs the CSI bit sequence.

    Abstract: Embodiments of this disclosure enhance the error detection performance of parallel polar encoding by cross-concatenating parity bits between segments of information bits transmitted over different sets of sub-channels. In one embodiment, a first segment of information bits is transmitted over a first set of sub-channels, and at least a second segment of information bits, and a masked parity bit, are transmitted over a second set of sub-channels. A value of the masked parity bit is equal to a bitwise combination of a first parity bit computed from the first segment of information bits and a second parity bit computed from the second segment of information bits. The bitwise combination may be a bitwise AND, a bitwise OR, or a bitwise XOR of the respective parity bits.

    Abstract: Embodiments of this application disclose a polar coding method, apparatus, and device, so as to reduce storage overheads of a system. A sequence for polar coding is obtained based on a length M of a target polar code, wherein the sequence comprises L sequence numbers, ordering of the L sequence numbers in the sequence is the same as ordering of the L sequence numbers in a maximum mother code sequence, wherein the maximum mother code sequence is obtained by sorting N sequence numbers of N polarized channels in ascending order or descending order of reliability metrics, wherein L and N are integer power of 2, M is smaller than or equal to L, L is smaller than or equal to N.
