Methods and apparatus are presented for H ARQ process dynamic memory management. A method for dynamically managing memory for storing data associated with H ARQ processes is presented, which includes receiving a packet associated with a H-ARQ process, determining if a free memory location is available in a H-ARQ buffer, assigning the packet to the free memory location, determining if the packet was successfully decoded, and retaining the packet in the assigned memory location for combination with a subsequent packet retransmission if the packet was not successfully decoded. Also presented are apparatus having logic configured to perform the presented methods.

La présente invention concerne des procédés et des appareils pour la gestion de mémoire dynamique à procédé H-ARQ. L'invention concerne un procédé pour gérer dynamiquement la mémoire afin de stocker des données associées aux procédés H-ARQ. Il passe par la réception d'un paquet associé à un procédé H-ARQ, la détermination du fait qu'un premier emplacement de mémoire libre est disponible dans un tampon H-ARQ, l'assignation du paquet à l'emplacement de mémoire libre, la détermination du fait que le paquet a bien été décodé et la retenue du paquet dans l'emplacement de mémoire assigné pour une combinaison avec une retransmission ultérieure du paquet si le paquet a bien été décodé. L'invention concerne également des appareils ayant une logique configurée pour réaliser les procédés présentés.
