Abstract: A terminal apparatus receives a parameter that is configured by a network apparatus and that is used to calculate an update period, where the update period is used to indicate time at which the terminal apparatus receives an uplink time-frequency synchronization parameter. The terminal apparatus receives an updated uplink time-frequency synchronization parameter based on the update period. The network apparatus configures the parameter for calculating the update period, so that the terminal apparatus can update the uplink time-frequency synchronization parameter in time.

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.
