1. A method for executing multipath communication at a target communication device, the method comprising:
obtaining, from a source communication device, a plurality of data packets via two or more different paths, wherein:
a header of each data packet of the plurality of data packets comprises packet information,
the packet information is indicative of an association among the plurality of data packets,
the packet information in each data packet at the source communication device is the same as the packet information in each data packet at the target communication device irrespective of different radio access technologies, communication protocols, or radio links used in the two or more different paths, and
the plurality of data packets comprises different data packets having different payload or duplicate data packets having a copy of same payload;
identifying a first set of data packets from the plurality of data packets received via a first path of the two or more different paths and a second set of data packets from the plurality of data packets received via a second path of the two or more different paths based on the packet information; and
mapping an uplink sequence number to a downlink sequence number for each data packet of the first set of data packets based on the packet information, wherein the uplink sequence number is received in a specified network layer from the source communication device, wherein the uplink sequence number is mapped to the downlink sequence number in the specified network layer, and wherein the specified network layer is a service adaptation protocol layer.
