Abstract: This application provides a coding method and apparatus, and a device. The method includes: dividing, by a sending device, a subchannel location sequence number set into at least two mutually exclusive subsets based on an interleaving operation, where a subchannel location in each subset still belongs to the subset and does not belong to another subset after any quantity of interleaving operations are performed; determining, by the sending device, an information bit location set and a frozen bit location set of a to-be-coded polar polar code based on the at least two mutually exclusive subsets; and coding, by the sending device, the to-be-coded polar code based on the information bit location set and the frozen bit location set.

Abstract: Embodiments provide a data transmission method and a related device. Under the method, after determining a first data packet to be sent to a receive end, a transmit end may generate a second data packet based on the first data packet, encode the second data packet, and send an encoded second data packet. A length of the second data packet is greater than a length of the first data packet. In various embodiments, when sending a data packet to the receive end, the transmit end may generate a longer data packet from a shorter data packet through combination, and send the longer data packet to the receive end after channel coding. In this way, a relatively high channel coding gain can be obtained during data transmission, and a relatively high bit error rate of short packet transmission is avoided, so that data transmission reliability can be improved.
