Abstract
(EN) An HARQ feedback processing method is executed in a UE. The UE transmits a hybrid automatic repeat request (HARQ) feedback signal of a downlink transmission, such a semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH), and determines whether a collision event occur in such a transmission attempt. The UE solve the collision by relocating transmission time of the HARQ feedback signal, or performing preemption or multiplexing operation for the HARQ feedback signal. The relocated transmission time may be measured in slots or symbols, and can be flexibly adjusted within a time window associated with a service type of the downlink transmission.
(FR) Selon la présente invention, un procédé de traitement de rétroaction HARQ est exécuté dans un UE. L'UE transmet un signal de rétroaction de demande de répétition automatique Hybride (HARQ) d'une transmission de liaison descendante, tel qu'un canal partagé de liaison descendante physique (PDSCH) de planification semi-persistante (SPS), et détermine si un événement de collision se produit dans une telle tentative de transmission. L'UE résout la collision en relocalisant le temps de transmission du signal de rétroaction HARQ, ou en effectuant une opération de préemption ou de multiplexage pour le signal de rétroaction HARQ. Le temps de transmission relocalisé peut être mesuré dans des intervalles ou des symboles, et peut être ajusté de manière flexible à l'intérieur d'une fenêtre temporelle associée à un type de service de la transmission en liaison descendante.
