Abstract
(EN) A UE can receive a first PDSCH on the basis of first scheduling information related to a first priority, receive a second PDSCH on the basis of second scheduling information related to a second priority, generate first HARQ-ACK information having the first priority on the basis of the reception of the first PDSCH, generate second HARQ-ACK information having the second priority on the basis of the reception of the second PDSCH, defer the transmission of the first HARQ-ACK having the first priority to a third slot on the basis that the transmission of a first HARQ-ACK for the first PDSCH overlaps with a downlink symbol in a first slot determined on the basis of a first PDSCH-to-HARQ-ACK_feedback timing value for the first PDSCH, and defer the transmission of a second HARQ-ACK having the second priority to a fourth slot on the basis that the transmission of the second HARQ-ACK overlaps with a downlink symbol in a second slot determined on the basis of a second PDSCH-to-HARQ-ACK_feedback timing value for the second PDSCH.
(FR) Un UE peut recevoir un premier PDSCH sur la base de premières informations de planification relatives à une première priorité, recevoir un second PDSCH sur la base de secondes informations de planification relatives à une seconde priorité, générer des premières informations HARQ-ACK ayant la première priorité sur la base de la réception du premier PDSCH, générer des secondes informations HARQ-ACK ayant la seconde priorité sur la base de la réception du second PDSCH, reporter la transmission du premier HARQ-ACK ayant la première priorité à un troisième créneau sur la base que la transmission d'un premier HARQ-ACK pour le premier PDSCH chevauche un symbole de liaison descendante dans un premier créneau déterminé sur la base d'une première valeur de cadencement de PDSCH-à-HARQ-ACK_rétroaction pour le premier PDSCH, et reporter la transmission d'un second HARQ-ACK ayant la seconde priorité à un quatrième créneau sur la base que la transmission du second HARQ-ACK chevauche un symbole de liaison descendante dans un second créneau déterminé sur la base d'une seconde valeur de cadencement de PDSCH-à-HARQ-ACK_rétroaction pour le second PDSCH.
(KO) UE는 제1 우선순위와 관련된 제1 스케줄링 정보를 기반으로 제1 PDSCH를 수신하고, 제2 우선순위와 관련된 제2 스케줄링 정보를 기반으로 제2 PDSCH를 수신; 상기 제1 PDSCH를 수신한 것을 기반으로 상기 제1 우선순위를 가진 제1 HARQ-ACK 정보를 생성하고, 상기 제2 PDSCH를 수신한 것을 기반으로 상기 제2 우선순위를 가진 제2 HARQ-ACK 정보를 생성; 상기 제1 PDSCH에 대한 제1 HARQ-ACK의 전송이 상기 제1 PDSCH에 대한 제1 PDSCH-to-HARQ-ACK_피드백 타이밍 값을 기반으로 결정된 제1 슬롯에서 하향링크 심볼과 중첩하는 것을 기반으로, 상기 제1 우선순위를 가진 상기 제1 HARQ-ACK의 전송을 제3 슬롯으로 미루고, 상기 제2 PDSCH에 대한 제2 PDSCH-to-HARQ-ACK_피드백 타이밍 값을 기반으로 결정된 제2 슬롯에서 하향링크 심볼과 중첩하는 것을 기반으로, 상기 제2 우선순위를 가진 상기 제2 HARQ-ACK의 전송을 제4 슬롯으로 미룰 수 있다.
