Abstract: This application provides a data processing method and apparatus, and a computer storage medium. When a PDCP entity over a UM DRB is re-established, or when a cell handover occurs and the PDCP entity over a UM DRB uses a key used before the handover, the PDCP entity determines a first SDU, where the first SDU is an SDU that is associated with a sequence number by the PDCP entity but whose corresponding data has not been transmitted through an air interface; and delivers a PDU corresponding to the first SDU to an RLC entity. Data corresponding to the first SDU is redelivered, to avoid a data packet loss caused by preprocessing of the PDCP entity.

Abstract: A slot scheduling method and apparatus are provided. A determined slot includes a first slot, the first slot includes a first idle time, and a time interval between a start moment of the first idle time and a start moment of the first slot is less than or equal to a preset time interval threshold, or a time interval between a start moment of the first idle time and an end moment of at least one OFDM symbol that is in the first slot and that is used to transmit control signaling is less than or equal to a preset time interval threshold. No first service is scheduled in the first idle time, thereby providing a transmission opportunity for a second service. In addition, time-domain locations of uplink transmission and downlink transmission of the first service and the second service do not overlap.

Abstract: Example polar coding methods and apparatus are described. One example method includes determining a sequence used to code to-be-coded bits. Polar coding is performed on the to-be-coded bits by using the sequence to obtain coded bits. The sequence is used to represent a reliability order of N polarized channels, N is a mother code length of a polar code, and N is a positive integer power of 2.

Abstract: This application relates to the field of communications technologies, and discloses a polar code encoding method and apparatus, to improve accuracy of reliability computation and sorting of polar channels. The method is: obtaining a first sequence used to encode K to-be-encoded bits, where the first sequence includes sequence numbers of N polar channels, and the sequence numbers of the N polar channels are arranged in the first sequence based on corresponding reliabilities of the N polar channels, where K is a positive integer, N is a mother code length of a polar code, N is a positive integer that is a power of 2, and K≤N; selecting sequence numbers of K polar channels from the first sequence in descending order of the reliabilities; and placing the to-be-encoded bits based on the selected sequence numbers of the K polar channels, and performing polar code encoding on the to-be-encoded bits.
