Abstract
(EN)
A method for transmitting, by means of a terminal, hybrid automatic repeat request acknowledgement (HARQ-ACK) information in a wireless communication system, according to one embodiment of the present disclosure, comprises: a step for receiving a first physical downlink shared channel (PDSCH) from a first transmission and reception point (TRP) and receiving a second PDSCH from a second TRP; and a step for transmitting at least one HARQ-ACK codebook including first HARQ-ACK bits for the first PDSCH and second HARQ-ACK bits for the second PDSCH, wherein the first PDSCH and the second PDSCH may be jointly transmitted at the first TRP and the second TRP on the basis of different downlink control information (DCI).
(FR)
Selon un mode de réalisation de la présente invention, un procédé d'émission, au moyen d'un terminal, d'informations d'accusé de réception de demande de répétition automatique hybride (HARQ-ACK) dans un système de communication sans fil comprend : une étape de réception d'un premier canal physique partagé de liaison descendante (PDSCH), à partir d'un premier point d'émission et de réception (TRP) et de réception d'un second PDSCH, à partir d'un second TRP ; et une étape d'émission d'au moins un livre de codes HARQ-ACK comprenant des premiers bits HARQ-ACK pour le premier PDSCH et des seconds bits HARQ-ACK pour le second PDSCH, le premier PDSCH et le second PDSCH pouvant être émis conjointement, au niveau du premier TRP et du second TRP, en fonction de différentes informations de commande de liaison descendante (DCI).
