Method for transporting real-time data frames comprising at least two bit portions having different relevance; corresponding transmitter and receiver

摘要

The present invention relates to a method for transporting real-time data from a transmitter to a receiver on a radio packet communication network, the real time data entity being generated at the transmitter and comprising at least two bit portions having different relevance, each real time data entities being encapsulated in a radio block and submitted to a modulation and coding scheme (M, C) before transmission. According to the present invention, at least one portion of a real-time data frame is repeated in several radio blocks to create redundancy. This redundancy compensates for a low efficient Modulation and Coding Scheme especially for the bit portions of the real-time data entity having the highest relevance (class A bits). At the receiver side, the different copies of the repeated bit portion are extracted from the received radio blocks and processed in order to eliminate the transmission errors.
