Title
(EN) METHOD FOR PROVIDING ERROR CORRECTION USING SELECTIVE AUTOMATIC REPEAT REQUESTS IN A PACKET-SWITCHED COMMUNICATION SYSTEM
(FR) METHODE DE CORRECTION D'ERREUR FAISAINT APPEL A UNE REPETITION AUTOMATIQUE SELECTIVE DES DEMANDES DANS UN SYSTEME DE COMMUNICATION A COMMUTATION PAR PAQUETS
Abstract
(EN)
The method reduces transmission delay by using a selective-repeat automatic repeat request (104), ARQ, error detection scheme in a packet-switched data communication system. The invention provides a method for a subscriber unit to transmit acknewledgment information using a contention-free channel access scheme in addition to providing for a base control unit to interrupt a packet currently being transmitted in order to retransmit segments of the packet when the segments have errors (108).
(FR)
Procédé de réduction du délai de transmission mettant en ÷uvre une répétition automatique sélective des demandes (104) (ARQ) et un système de détection d'erreur dans un réseau de communication de données à commutation par paquets. L'invention repose sur un procédé selon lequel un poste d'abonné transmet des informations de confirmation de réception en utilisant un système d'accès aux canaux sans conflits et un poste de régulation de base interrompt un paquet en cours de transmission afin de retransmettre des tronçons du paquet lorsque ces tronçons comportent des erreurs (108).
