Abstract: The present invention relates to a method for detecting errors in a real-time data entity received at a receiver of a radio communication network, the real-time data entity being transported in a radio block over a radio channel, the real time data frame comprising at least two bit portions having different relevance. According to the present invention, the method comprises the steps of: i estimating a first bit error rate for a first bit portion; ii checking if the first estimated bit error rate is higher than a first predefined threshold, iii estimating a second bit error rate for a second bit portion having a lower relevance than the first bit portion; iv checking if the second estimated bit error rate is higher than a second predefined threshold higher than the first predefined threshold, v replacing the entire real-time data entity by using a concealment algortihm if one of the checks is true.

Abstract: 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 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. 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.
