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: Aspects of this disclosure provide a technique for implementing polar encoding with incremental redundancy HARQ re-transmission. In particular, a transmitter encodes a message using different polar codes to obtain a first codeword and a second codeword that is twice the length of the first codeword, and transmit the first codeword as an original transmission, and the second half of the second codeword as a re-transmission without transmitting the first half of the second codeword. Information bits that are common to both the first codeword and the second half of the second codeword is mapped to more-reliable bit-locations in the second half of the second codeword. Decoded bit values for the common information in the original transmission and retransmission is compared by the receiver to perform a parity check.
