A method and apparatus for iterative decoding of a coded information signal that allows quality of service, QoS, parameters to be dynamically balanced in a telecommunications system. In an embodiment, an iterative decoder performs decoding on a coded information signal based on minimum and maximum values for the number of decoding iterations to be performed for a particular data transmission. The minimum and maximum values for the number of decoding iterations are determined according to QoS requirements that are given in terms of BER and Tdelay.

[ What is claimed is:] [1.]1. A method of iteratively decoding a coded information signal, said method comprising the steps of:determining a minimum and maximum number of iterations of iterative decoding to be performed on the information signal, said minimum number of iterations determined from a bit error rate value and said maximum number of iterations determined from a time delay value;performing N iterations of iterative decoding on the coded information signal, wherein N is a number at least equal to said minimum number of iterations;determining if a result of said N iterations meets predetermined error criteria; andin response to a negative determination in said step of determining:repetitively performing at least one other iteration of iterative decoding on the coded information signal and determining if a result of said at least one other iteration meets said predetermined error criteria, until it is determined that said result of said at least one other iteration meets said predetermined error criteria, or until the total number of iterations performed on the information signal is equal to said the maximum number of iterations.
