PACKET ORDER IDENTIFICATION WITH REDUCED OVERHEAD IN PACKETIZED DATA TRANSMISSION

摘要

A transmitting device comprising: a transmitter for transmitting data to a receiving device; and a controller for formatting the data to be transmitted from the transmitter, by dividing the data amongst a plurality of packets. The controller is configured to package each respective one of the packets with only a respective portion of an index sequence as an identifier field for distinguishing between the packets within the sequence, wherein at least one of the portions is alone insufficient to identify its respective packet. The controller is further configured to control the transmitter to transmit the packets including the respective portions of the index sequence, ordered such that the index sequence repeats cyclically over the transmission of the packets; thereby enabling the receiving device to determine a respective position in the index sequence for each of the packets by referencing a plurality of the portions together, and to thereby identify the packets.
