Abstract
(EN)
Presented in the present specification are a method for transmitting/receiving a physical downlink shared channel in a wireless communication system, and a device therefor. Particularly, the method performed by a terminal comprises the steps of: receiving configuration information about a control resource set (CORESET) of a first group and a CORESET of a second group; receiving a first physical downlink control channel (PDCCH) from the CORESET of the first group; receiving a first PDSCH on the basis of the first PDCCH; receiving a second PDCCH from the CORESET of the second group; and receiving a second PDSCH on the basis of the second PDCCH, wherein the first PDSCH and/or the second PDSCH can be received, on the basis of being scheduled within a scheduling offset, by using a default CORESET.

La présente invention concerne un procédé de transmission et de réception d'un canal de liaison descendante dans un système de communication sans fil, et un dispositif associé. En particulier, le procédé mis en œuvre par un terminal comprend les étapes consistant à : recevoir des informations de configuration concernant un ensemble de ressources de commande (CORESET) d'un premier groupe et d'un CORESET d'un second groupe ; recevoir un premier canal de commande de liaison descendante physique (PDCCH) à partir du CORESET du premier groupe ; recevoir un premier PDSCH sur la base du premier PDCCH ; recevoir un second PDCCH à partir du CORESET du second groupe ; et recevoir un second PDSCH sur la base du second PDCCH, le premier PDSCH et/ou le second PDSCH pouvant être reçus, sur la base d'une planification dans un décalage de planification, en utilisant un CORESET par défaut.
