`The present invention provides an apparatus and method tor transmitting and receiving packet data in a mobile communication system supporting Hybrid Automatic Repeat reQuest (HARQ), and in particular, provides a method and apparatus for performing HARQ retransmission on a packet received through persistent resources where no HARQ process identifier is transmitted. The invention provides HARQ soft combining by providing a mapping relation between a packet received through persistent resources and a retransmitted HARQ packet. In addition, when there are several HARQ packets received through persistent resources at an arbitrary timing, the invention controls to determine with which packet an arbitrary retransmission packet should be combined, thereby allowing the corresponding processor to perform correct soft combining. Therefore, the invention can improve HARQ performance of persistent resources without increasing complexity of the reception apparatus.
L'invention concerne un dispositif et procédé pour transmettre et recevoir des données de paquets dans un système de communication mobile acceptant une demande de répétition automatique hybride (HARQ), et en particulier un procédé et un dispositif pour mettre en uvre une retransmission de HARQ sur un paquet reçu par des ressources permanentes lorsqu'aucun identifiant de processus HARQ n'est transmis. L'invention permet une combinaison souple de HARQ par l'établissement d'une relation de mappage entre un paquet reçu par l'intermédiaire de ressources permanentes et un paquet HARQ retransmis. De plus, lorsque plusieurs paquets HARQ sont reçus par l'intermédiaire de ressources permanentes à une temporisation arbitraire, l'invention permet de déterminer à quel paquet un paquet de retransmission arbitraire doit être combiné pour permettre au processeur correspondant de mettre en uvre la combinaison souple correcte. L'invention permet ainsi d'améliorer l'efficacité de HARQ de ressources permanentes sans accroître la complexité du dispositif de réception.
