METHOD AND APPARATUS FOR DELTA DATA STORAGE
(FR)
PROCÉDÉ ET APPAREIL POUR MÉMORISATION DE DONNÉES DELTA
Abstract:
(EN)
Various methods for implementing delta data storage, for example, within a hybrid automatic repeat request (HARQ) buffer, are provided. One example method includes receiving a redundancy version including a plurality of redundancy version bits and soft combining the redundancy version bits with corresponding buffered bits to generate corresponding soft combined bits. The example method further includes comparing the soft combined bits with the corresponding buffered bits to identify changed bits and unchanged bits, storing the changed bits in a buffer to thereby replace the buffered bits that correspond to the changed bits. Similar example apparatuses are also provided.
(FR)
Selon l'invention, on propose divers procédés de mise en œuvre d'une mémorisation de données delta, par exemple à dans un tampon de demande de répétition automatique hybride (HARQ). Un exemple de procédé comprend la réception d'une version redondante comprenant une pluralité d'éléments binaires de version redondante et la combinaison logicielle des éléments binaires de version redondante avec des éléments binaires correspondants mis en tampon afin de générer des éléments binaires combinés logiciels correspondants. L'exemple de procédé comprend en outre la comparaison des éléments binaires combinés de façon logicielle avec les éléments binaires mis en tampon correspondants afin d'identifier les éléments binaires modifiés et les éléments binaires non modifiés, de mémoriser les éléments binaires modifiés dans un tampon afin de remplacer ainsi les éléments binaires mis en tampon qui correspondent aux éléments binaires modifiés. L'invention porte également sur des exemples d'appareils similaires.
