Title (EN) METHOD TO MANAGE DOWNLINK DATA DELIVERY STATUS
(FR) PROCÉDÉ DE GESTION D'ÉTAT DE DISTRIBUTION DE DONNÉES DE LIAISON DESCENDANTE
Abstract:
(EN) The generation and use of a modified DDDS, suitable for RLC AM and RLC UM, is disclosed herein. The modified DDDS optionally includes an IE specifying a highest sequence number f a packet successfully delivered to a wireless terminal. Node B, which is in wireless communication with a wireless terminal, sends the modified DDDS to Node A, where Node A sends DL data packets to Node B for transmission to the wireless terminal responsive to the received modified DDDS.
(FR) L'invention concerne la génération et l'utilisation d'un DDDS modifié, approprié pour RLC AM et RLC UM. Le DDDS modifié comprend éventuellement un IE spécifiant un numéro de séquence le plus élevé d'un paquet délivré avec succès à un terminal sans fil. Le nœud B, qui est en communication sans fil avec un terminal sans fil, envoie le DDDS modifié au nœud A, le nœud A envoie des paquets de données DL au nœud B pour une transmission au terminal sans fil en réponse au DDDS modifié reçu.
