Abstract: Embodiments of this application provide a data transmission method, a communications device, and a storage medium, to reduce pressure caused by a quantity of cross connections between intermediate nodes to the intermediate nodes in a network. In an embodiment of this application, a first communications device obtains Q first code block streams, and obtains a to-be-sent second code block stream based on the Q first code block streams. Q downlink ports are in a one-to-one correspondence with the Q first code block streams, the Q downlink ports correspond to S code block groups, one code block in the Q first code block streams corresponds to one code block group, and the second code block stream obtained by the first communications device includes L code block sets; and for each of the L code block sets, the code block set includes K code blocks corresponding to each of the S code block groups. In the solutions provided in this embodiment of this application, code block streams are multiplexed at a code block granularity, so that a quantity of cross connections between intermediate nodes in a network can be reduced, thereby reducing pressure on network management and operation and maintenance.

Abstract: This application provides data transmission methods, devices, and systems. In one implementation, a method comprises: receiving, by a central device of a wireless network, at least one first data packet sent by a remote device of the wireless network, wherein each of the at least one first data packet comprises a sequence number indicating a relative location of a payload of the corresponding first data packet in a second data packet; reordering, by the central device, the at least one first data packet, based on the sequence number of each of the at least one first data packet, to obtain the second data packet; and sending, by the central device, the second data packet.
