Data transmission method, sending device and receiving device

A sending device, comprising:

• a processor;
• a memory storing instructions executable by the processor;
• and
• a transmitter,
• wherein the processor is configured to:
• segment or concatenate data packets of a first service to be transmitted to a same receiving device, so as to generate a plurality of segments of data packets;
• and
• package and number, for multiple radio access technologies, the plurality of segments of data packets, wherein the multiple radio access technologies adopt an aggregation mode, and the aggregation mode indicates a mode in which different radio access technologies are used to transmit different contents;
• and
• wherein the transmitter is configured to send the packaged data packets to the receiving device by using corresponding radio access technologies according to the numbers
• wherein the multiple radio access technologies comprise a first radio access technology and a second radio access technology, the plurality of segments of data packets comprise a first segment of data packets and a second segment of data packets, and the first segment of data packets and the second segment of data packets are respectively transmitted in the aggregation mode by using the first radio access technology and the second radio access technology.

A receiving device, comprising:

• a processor;
• and
• a memory storing instructions executable by the processor,
• a receiver configured to receive data packets of a first service sent by a sending device, wherein the data packets are sent by the sending device using multiple radio access technologies, the multiple radio access technologies adopt an aggregation mode, and the aggregation mode indicates a mode in which different radio access technologies are used to transmit different contents;
• wherein the processor is arranged to recover the data packets received by the receiver;
• and
• wherein the processor is further arranged to perform accuracy check on the recovered data packets
• wherein the multiple radio access technologies comprise a first radio access technology and a second radio access technology, the recovered data packets comprise a first data packet and a second data packet, and the first data packet and the second data packet are respectively transmitted in the aggregation mode by using the first radio access technology and the second radio access technology.
