Abstract
(EN)
The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and apparatus for transmitting uplink control information in the event a plurality of cells are constructed, wherein the method comprises the following steps: receiving a PDCCH and/or a PDSCH; generating acknowledgement information on the PDCCH and/or PDSCH; and, if acknowledgement information transmission timing and channel state information transmission timing collide with each other, dropping the channel state information and transmitting only the acknowledgement information, or transmitting the acknowledgement information and the channel state information together in accordance with a predetermined condition.
(FR)
La présente invention concerne un système de communication sans fil. Plus particulièrement, la présente invention concerne un procédé et un appareil pour transmettre des informations de commande de liaison montante dans le cas où une pluralité de cellules sont construites, le procédé comprenant les étapes suivantes consistant à : recevoir un PDCCH et/ou un PDSCH; générer des informations d'acquittement sur le PDCCH et/ou le PDSCH; et, si une collision entre la synchronisation de transmission d'informations d'acquittement et la synchronisation de transmission d'informations d'état de canal se produit, abandonner les informations d'état de canal et ne transmettre que les informations d'acquittement, ou transmettre les informations d'acquittement et les informations d'état de canal ensemble selon une condition prédéterminée.
