Title
(EN) LAYERED MISSING PACKET DETECTION
(FR) DÉTECTION D'UN PAQUET MANQUANT AGENCÉ EN COUCHES
Abstract
(EN) A wireless communication device is described. The wireless communication device includes a memory and a processor in electronic communication with the memory. The processor is configured to determine a packet data convergence protocol (PDCP) packet count corresponding to a last radio link control (RLC) packet received in-sequence. The processor is also configured to detect a missing PDCP packet based on a comparison of the PDCP packet count and a sequence number of a last PDCP packet received in-sequence.
(FR) La présente invention concerne un dispositif de communication sans fil. Le dispositif de communication sans fil contient une mémoire et un processeur en communication électronique avec la mémoire. Le processeur est configuré pour : déterminer un compte de paquets de protocole de convergence de données par paquets (PDCP) correspondant à un dernier paquet de commande de liaison radio (RLC) reçu dans une séquence ; et détecter un paquet PDCP manquant sur la base d'une comparaison du compte de paquets PDCP et d'un numéro de séquence d'un dernier paquet PDCP reçu dans une séquence.
