Title (EN) HARQ-ACK FEEDBACK TIMING FOR SPS PDSCH
(FR) SYNCHRONISATION DE RÉTROACTION HARQ-ACK POUR UN SPS-PDSCH
Abstract:
(EN) Apparatuses, methods, and systems are disclosed for determining hybrid automatic repeat request acknowledgement ("HARQ-ACK") feedback timing for semi-persistent scheduling ("SPS") physical downlink shared channel ("PDSCH"). One apparatus (300) includes a receiver (335) that receives (805) a radio resource control ("RRC") signal from a base unit and a processor (305) that determines (810) a feedback timing for a SPS PDSCH transmission. The processor (305) uses the RRC signal to determine the feedback timing. The apparatus also includes a transmitter (330) that transmits (815) HARQ-ACK feedback to the base unit in a first slot defined by the feedback timing information. Here, the HARQ-ACK feedback indicating whether the SPS PDSCH transmission was successfully received.
(FR) L'invention concerne des appareils, des procédés, et des systèmes permettant de déterminer un instant de rétroaction d'accusé de réception de requête automatique de répétition hybride (HARQ-ACK) pour un canal partagé de liaison descendante physique (PDSCH) de programmation semi-persistante (SPS). Un appareil (300) comprend : un récepteur (335) qui reçoit (805) un signal de gestion des ressources radioélectriques (RRC), d'une unité de base ; et un processeur (305) qui détermine (810) un instant de rétroaction pour la transmission d'un SPS-PDSCH. Le processeur (305) utilise le signal RRC pour déterminer l'instant de rétroaction. L'appareil comprend également un émetteur (330) qui transmet (815) une rétroaction HARQ-ACK à l'unité de base dans un premier intervalle défini par les informations d'instant de rétroaction. Ici, la rétroaction HARQ-ACK indique si la transmission du SPS-PDSCH a été reçue avec succès.
