Title:
SYSTEM AND METHOD OF HEADER COMPRESSION FOR ONLINE NETWORK CODES
Document Type and Number:
WIPO Patent Application WO/2016/188406
Kind Code:
A1
Abstract:
Embodiments are provided for header compression with online network codes. A header formulation is used in accordance with the network codes to reduce the header overhead. An agent node between a source of packets and a user equipment (UE) adds to a header in the packets block labels corresponding to blocks of data in the packets. The agent node further adds, to a payload portion of the packets, start and end times for transmitting the blocks. The blocks of data are encoded using an online network coding scheme and the packets are sent to an access node serving the UE. The access node receives the packets, compresses the header by compressing bits of the block labels based on a pre-defined finite number of paths between the agent node and a plurality of access nodes components serving the UE, and sends the compressed header in the packets to the UE.
