Abstract
(EN)
The present invention relates to a wireless communication system, and more particularly, to an uplink control information transmitting/receiving method and device. A method of transmitting acknowledgement information in a wireless communication system by a terminal according to an embodiment of the present invention includes: determining whether transmission of a scheduling request is set in one subframe where acknowledgement information on downlink transmission is to be transmitted; determining a Physical Uplink Control Channel (PUCCH) format and a resource with which the acknowledgement information is to be transmitted; and transmitting the acknowledgement information by using the PUCCH format and the resource. Here, when the transmission of the scheduling request is set in the one subframe and the acknowledgement information corresponds to only a Physical Downlink Shared Channel (PDSCH) received on only a Primary Cell (PCell), the acknowledgement information and the scheduling request may be transmitted using PUCCH format 1a/1b.

L'invention concerne un système de communication sans fil et, plus particulièrement, un procédé et un dispositif d'émission/réception d'information de commande dans le sens montant. Un procédé pour l'émission par un terminal d'une information d'accusé de réception dans un système de communication sans fil selon un mode de réalisation de la présente invention consiste à déterminer si l'émission d'une requête d'ordonnancement est activée dans une sous-trame, une information d'accusé de réception sur l'émission en sens descendant devant être émise, à déterminer un format PUCCH (canal de commande montant physique) et une ressource devant servir à l'émission de l'information d'accusé de réception et à émettre l'information d'accusé de réception à l'aide de ce format PUCCH et de cette ressource. Si l'émission de la requête d'ordonnancement est activée dans la sous-trame en question et si l'information d'accusé de réception correspond à un seul canal partagé descendant physique (PDSCH) reçu uniquement sur une cellule primaire (Pcell), l'information d'accusé de réception et la requête d'ordonnancement peuvent être transmises à l'aide du format PUCCH 1a/1b.
