SYSTEM AND METHOD FOR JOINT TRANSMISSION OVER LICENSED AND UNLICENSED BANDS USING FOUNTAIN CODES

摘要

Transporting different sets of encoded packets generated from the same traffic flow over the respective licensed and unlicensed bands may provide bandwidth utilization efficiencies in addition to enabling more robust data streaming. More specifically, a transmit point may encode a traffic flow using a fountain code to obtain encoded packets, and then transmit different subsets of the encoded packets over the respective licensed and unlicensed bands. The fountain code may be applied at the physical layer, the media access control (MAC) layer, the radio link control (RLC) layer, or the application layer. The respective subsets of packets may be transmitted over the licensed and unlicensed bands at different rates. Different coding rates may be used over the respective bands.
