    Abstract: This application provides a scheduling method and apparatus. The method includes: a network device uses a scheduling model applicable to K users for one or more times, and determines a scheduled terminal device based on scheduling weights output by the scheduling model for one or more times. Each time the scheduling model is used, status information of K terminal devices in n to-be-scheduled terminal devices is input to the scheduling model, and the scheduling model outputs scheduling weights respectively corresponding to the K terminal devices, where K is an integer greater than 1, and n is an integer greater than K. Therefore, regardless of a quantity of to-be-scheduled terminal devices in a communication system, the network device may reuse the scheduling model without re-establishing a scheduling model, so that the scheduling model is expandable and applicable to scenarios in which quantities of to-be-scheduled terminal devices are different.

    Abstract: This application discloses a polar code interleaving processing method and apparatus. The method includes: determining N to-be-encoded bits, where N is a positive integer; obtaining a first sequence that includes sequence numbers of N polarized channels, where the first sequence is used to indicate a reliability order of the N polarized channels; performing polar encoding on the N to-be-encoded bits to obtain encoded bits; and performing interleaving processing on the encoded bits based on the first sequence. Because the first sequence used to indicate the reliability of the polarized channels is a sequence already existing in a polar code encoding process, no additional storage resource needs to be used to store the first sequence in the interleaving processing process, thereby reducing use of storage resources.

    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: Embodiments of polar encoding/decoding methods and apparatuses are described. CRC encoding is performed on an information block to obtain a CRC encoded block with a length of B, where a CRC length is Lcrc, an information block length is K, and B=K+Lcrc. The CRC encoded block is interleaved. Lpc CRC bits in the interleaved encoded block are located between bits of the information block. Each CRC bit of the Lpc CRC bits is located after all bits checked by using the CRC bit. Lpc is an integer greater than 0 and less than Lcrc. The interleaved encoded block is mapped to information bits. A frozen bit is set to an agreed fixed value. Polar encoding is performed on the information bits and the frozen bit to obtain a polar encoded codeword to improve performance of a CA-polar code.

    Abstract: Example information transmission methods and devices are disclosed. One example method is applied to a network device and includes determining CRC bits of to-be-sent information bits, concatenating the CRC bits and the to-be-sent information bits to obtain a first information sequence, and interleaving bits in the first information sequence in an interleaving manner or scrambling the bits in the first information sequence in a scrambling manner, to obtain a second information sequence, to ensure that bits at locations of the CRC bits after a cyclic shift cannot check bits at locations of the to-be-sent information bits after the cyclic shift. A cyclic shift is performed on the second information sequence to obtain a third information sequence, where a quantity of cyclically shifted bits is used to carry information about some bits of a system frame number, and the third information sequence is sent.
