Title (EN) RANDOM ACCESS SCHEME FOR PREVENTING UNNECESSARY RETRANSMISSION AND USER EQUIPMENT FOR THE SAME
(FR) MODALITÉS D'ACCÈS ALÉATOIRES POUR EMPÊCHER UNE RETRANSMISSION NON NÉCESSAIRE ET ÉQUIPEMENT D'UTILISATEUR POUR CELLES-CI
Abstract:
(EN) A random access scheme for preventing unnecessary retransmission and a user equipment for the same are disclosed. If a Contention Resolution (CR) timer expires in contention resolution during a random access procedure or if a Physical Downlink Control Channel (PDCCH) signal or a Physical Downlink Shared Channel (PDSCH) signal associated with the PDCCH signal does not match an identifier of a terminal, a Hybrid Automatic Repeat Request (HARQ) buffer for storing a Medium Access Control Packet Data Unit (MAC PDU) transmitted in the random access procedure is flushed such that unnecessary data retransmission can be prevented.
(FR) L'invention concerne des modalités d'accès aléatoires pour empêcher une retransmission non nécessaire et un équipement d'utilisateur pour celles-ci. Si un minuteur de résolution de conflits (CR) expire en résolution de conflits pendant une procédure d'excès aléatoire ou si un signal de canal physique de commande de liaison descendante (PDCCH) ou un signal de canal physique partagé de liaison descendante (PDSCH) associé au signal PDCCH ne correspond pas à un identifiant d'un terminal, un tampon de demande de répétition automatique hybride (HARQ) pour stocker une unité de données par paquet de commande d'accès au support (MAC PDU) transmise dans la procédure d'accès aléatoire est éliminé de sorte que la retransmission de données non nécessaire peut être empêchée.
