Title
(EN) AGGREGATING HARQ FEEDBACK
(FR) AGRÉGATION DE RÉTROACTION D'HARQ
Abstract
(EN)
Apparatuses, methods, and systems are disclosed for aggregating HARQ feedback and sidelink retransmission procedure. One apparatus 600 includes a transceiver 625 that transmits 805 SL data to a set of receiver V2X UEs 215 and listens 810 for SL feedback from the set of the receiver V2X UEs 215. Here, the SL feedback indicates whether a receiver V2X UE 215 successfully decoded the SL data transmission. The apparatus 600 also includes a processor 605 that aggregates 815 HARQ feedback and sends 820 an Aggregated Feedback message to a RAN node 210, the Aggregated Feedback message containing the aggregated HARQ feedback.

L'invention concerne des appareils, des procédés et des systèmes pour agréger une rétroaction d'HARQ et une procédure de retransmission de liaison latérale. Un appareil 600 comprend un émetteur-récepteur 625 qui transmet des données SL 805 à un ensemble d'UE V2X de réception 215 et écoute 810 une rétroaction SL à partir de l'ensemble des UE V2X de réception 215. Ici, la rétroaction SL indique si un UE V2X de réception a décodé avec succès la transmission de données SL. L'appareil 600 comprend également un processeur 605 qui agrège 815 une rétroaction d'HARQ et envoie 820 un message de rétroaction agrégée à un noeud RAN 210, le message de rétroaction agrégée contenant la rétroaction d'HARQ agrégée.
