Abstract: A sending method, a receiving method, an apparatus, a system, a device, and a storage medium. The receiving method includes: obtaining an encoded data block, where the encoded data block includes a plurality of data blocks, a plurality of first parity bits, and an FEC parity bit, the plurality of first parity bits are in one-to-one correspondence with the plurality of data blocks, and the FEC parity bit corresponds to the plurality of data blocks; and then checking the corresponding data blocks based on the plurality of first parity bits and/or the FEC parity bit, to obtain a decoding result of the encoded data block.

Abstract: An embodiment of this application provides a data transmission method. The method includes: A first communication apparatus sends an ith AM group to a second communication apparatus, and sends first data of a plurality of service flows to the second communication apparatus based on a mapping relationship. The first data is carried in M time units between the ith AM group and an (i+1)th AM group, the mapping relationship is a mapping relationship between a slot of a first calendar and the plurality of service flows, and the first calendar includes s slots. The M time units between the ith AM group and the (i+1)th AM group include N first counting periods, each time unit of the first counting period corresponds to one slot of the first calendar, and different time units of a same first counting period correspond to different slots of the first calendar.
