Title (EN) AVOIDING UNNECESSARY PROTOCOL DATA UNIT (PDU) TRANSMISSIONS
(FR) PROCÉDÉ PERMETTANT D'ÉVITER DES TRANSMISSIONS INUTILES D'UNITÉS DE DONNÉES DE PROTOCOLE
Abstract:
(EN) Aspects described herein relate to wireless communications. Protocol data units (PDUs) can be received at a network layer from one or more transmitting nodes using a link associated with each respective transmitting node. One or more missing PDUs can be detected based, at least in part, on sequence numbers of the received PDUs. A timer can be started based on the detection of the one or more missing PDUs. In response to expiration of the timer, and without receiving the one or more missing PDUs before the expiration of the timer, a lower network layer can be notified that the one or more missing PDUs are received to prevent attempted transmitting/retransmitting or other processing of the one or more missing PDUs.
(FR) Selon certains aspects, l'invention concerne les communications sans fil. Des unités de données de protocole (PDU) provenant d'un ou de plusieurs nœuds de transmission peuvent être reçues au niveau d'une couche de réseau au moyen d'une liaison associée à chaque nœud de transmission concerné. Une ou plusieurs PDU manquantes peuvent être détectées au moins en partie sur la base des numéros de séquence des PDU reçues. Un temporisateur peut être démarré sur la base de la détection de la ou des PDU manquantes. À l'expiration du temporisateur, et sans réception de la ou des PDU manquantes avant l'expiration du temporisateur, il peut être notifié à une couche de réseau inférieure que la ou les PDU manquantes sont reçues, de manière à empêcher une tentative de transmission/retransmission ou autre traitement de la ou des PDU manquantes.
