Apparatus, and an associated method, facilitates the efficient utilization of a channel (16) extending between a sending (12) and a receiving (14) station of a digital communication system. A block of symbols to be transmitted by the sending to the receiving station is encoded (134) utilizing a parallel-concatenated encoding technique. Selected encoded versions, or portions thereof, are transmitted (136) by the sending station to the receiving station. The receiving station decodes the signals received thereat. If recovery of the informational content of the block of symbols cannot be effectuated, a request is made to transmit additional encoded versions (138), or portions thereof, of the block of symbols.
L'invention concerne un appareil et un procédé associé, qui facilitent l'utilisation efficace d'une voie (16) reliant une station émettrice (12) à une station réceptrice (14) dans un système de communication numérique. On code (134) un bloc de symboles devant être transmis de la station émettrice à la station réceptrice, à l'aide d'une technique de codage parallèle concaténé. Des versions codées choisies, ou des parties de celles-ci, sont transmises (136) de la station émettrice à la station réceptrice. La station réceptrice décode les signaux qu'elle reçoit. Si le contenu d'information du bloc de symboles ne peut être récupéré, une demande est faite pour que des versions (138) codées supplémentaires du bloc de symboles, ou des parties de celles-ci, soient transmises.
