Title:
TRANSMISSION DEVICE, TRANSMISSION METHOD, RECEPTION DEVICE, AND RECEPTION METHOD
Document Type and Number:
WIPO Patent Application WO/2015/002007
Kind Code:
A1
Abstract:
This technology relates to a transmission device, a transmission method, a reception device, and a reception method, which enable header redundancy in packet communication to be suppressed. An area expressing packet length in a packet header is switched and set in accordance with the size of a payload of an input packet. In other words, in accordance with packet length, the area expressing packet length is switched into one from among: a short packet mode in which packet length is expressed using only the 5 bits of a packet length section (FH1-3) of a shortest fixed length header (FH1); a variable length mode in which packet length is expressed using the 11 bits of the packet length section (FH1-3) and a packet length section (VH1-1) of a variable length header (VH1); and an additional variable length mode in which packet length is expressed using the 16 bits of the packet length section (FH1-3), the packet length section (VH1-1), and a packet length section (AH1-2) of an additional header (AH1). This technology is applicable to broadcast communication.
