    Abstract: This application provides a polar code encoding method and apparatus. The method includes: segmenting, by a sending device, a to-be-encoded sequence according to a preset rule; determining a quantity of parity check frozen bits, locations of the parity check frozen bits, a quantity of information bits, locations of the information bits, a quantity of frozen bits, and locations of the frozen bits in each segment; then placing the information bits and the frozen bits at the corresponding locations; determining values of the parity check frozen bits; then performing polar code encoding on the to-be-encoded sequence; and sending an encoded sequence. According to this method, a process of determining the quantity of parity check frozen bits and the locations of the parity check frozen bits is simplified, thereby effectively improving processing efficiency.

    Abstract: The present disclosure relates to polar encoding methods and apparatus. One example method includes obtaining locations of information bits and frozen bits based on a reliability order of polar channels, where reliability of a polar channel corresponding to the information bits is higher than reliability of a polar channel corresponding to the frozen bits, performing cyclic redundancy check (CRC) encoding on an information block, mapping bits obtained after the CRC encoding to the information bits, determining at least one bit of the frozen bits as a check frozen bit, where a value of the check frozen bit is determined based on values of P information bits that are in information bits prior to the check frozen bit and that meet a preset condition, and performing polar encoding on the information bits, the check frozen bit, and a frozen bit other than the check frozen bit.

    Abstract: An encoding method, an encoding apparatus, a decoding method, and a decoding apparatus are provided. The encoding method includes: determining a size of a shift matrix based on a length of an information sequence and a length of an identifier sequence; constructing a check matrix based on the size of the shift matrix and a base matrix; and performing low-density parity-check LDPC encoding on the information sequence and the identifier sequence based on the check matrix. The identifier sequence is a non-all-zero sequence. Because the encoded codeword includes information of the identifier sequence, a receive device can identify whether information corresponding to the encoded codeword is addressed to the receive device, thereby improving information processing efficiency in the transmission.

    Abstract: Embodiments of the present invention provide a decoupling assembly, a multiple-antenna system, and a terminal, and relate to the field of communications technologies, to change a radiation direction of an electromagnetic wave, thereby achieving a decoupling effect in a relatively large frequency range. The multiple-antenna system includes a first antenna unit and a second antenna unit that are adjacent to each other. A decoupling assembly is disposed between the first antenna unit and the second antenna unit, and the decoupling assembly is made of an electromagnetic material with electrical anisotropy or electromagnetic bianisotropy, to reduce a coupling generated between the first antenna unit and the second antenna unit.

    Abstract: A network slice management method, a management unit, and a system, where the method includes receiving, by a first management unit, a first management request, where the first management request carries requirement information of a network slice or indication information, and the indication information is used to obtain the requirement information of the network slice. The method further includes determining, by the first management unit, requirement information of a subnet that forms the network slice. According to the method, the first management unit can determine the corresponding requirement information of the subnet based on the requirement information of the network slice.
