Title: METHODS AND ARRANGEMENT IN A DIGITAL TELECOMMUNICATIONS SYSTEM
Abstract:
The present invention relates to a method and an arrangement for communicating packet information in a digital telecommunications system. Through the invention is selected a set of designated communication resources (ch1-chn) from an available amount of resources. Every packet (P) is forward error correction encoded into an encoded packet (Pci), via one of at least two different coding schemes (ci), prior to being transmitted to a receiving party, over the designated communication resources (ch1-chn). An estimated transmission time is calculated for all combinations of coding scheme (ci) an relevant distribution (dj) of the encoded data blocks (B1-BΗ), in the encoded packet (PCi) over the set of designated communication resources (ch1-chn), and the combination (ci, dj) is selected, which minimises the estimated transmission time.
