Title
(EN) METHOD AND APPARATUS FOR TRANSMITTING HARQ-ACK FEEDBACK INFORMATION IN AN ENHANCED CARRIER AGGREGATION SYSTEM
(FR) PROCÉDÉ ET APPAREIL POUR LA TRANSMISSION D'INFORMATIONS DE RENVOI DE HARQ-ACK DANS UN SYSTÈME D'AGRÉGATION DE PORTEUSES AMÉLIORÉ
Abstract
(EN)
The present disclosure provides a method for transmitting hybrid automatic repeat-request acknowledgement (HARQ-ACK) feedback information in an enhanced carrier aggregation system. A user equipment (UE) determines the number of HARQ-ACK feedback information bits that the UE needs to transmit in an uplink subframe, and determines the number of uplink control information (UCI) bits to be transmitted in the uplink subframe based on the number of the HARQ-ACK feedback information bits, the number of channel state information (CSI) bits, and the number of scheduling request (SR) bits that need to be transmitted in the uplink subframe, and transmitting the UCI according to the PUCCH format and the resource for transmission of PUCCH determined. With the present disclosure, UCI information may be transmitted using different formats in different PUCCH formats.

La présente invention concerne un procédé de transmission d'informations de renvoi d'accusé de réception à demande de répétition automatique hybride (HARQ-ACK) dans un système d'agrégation de porteuses amélioré. Un équipement d'utilisateur (UE) détermine le nombre de bits d'informations de renvoi de HARQ-ACK dont l'UE a besoin pour transmettre dans une sous-trame en liaison montante, puis détermine le nombre de bits d'informations de commande en liaison montante (UCI) à transmettre dans la sous-trame en liaison montante, sur la base du nombre de bits d'informations de renvoi de HARQ-ACK, du nombre de bits d'informations d'état de canal (CSI) et du nombre de bits de demande de programmation (SR) qui ont besoin d'être transmis dans la sous-trame en liaison montante, puis transmet les UCI en fonction du format PUCCH et des ressources pour la transmission du PUCCH déterminés. Grâce à la présente invention, les informations UCI peuvent être transmises à l'aide de différents formats dans différents formats de PUCCH.
