(EN) METHOD AND APPARATUS FOR TRANSMITTING UPLINK CONTROL INFORMATION
(FR) PROCÉDÉ ET APPAREIL POUR TRANSMETTRE DES INFORMATIONS DE COMMANDE DE LIAISON MONTANTE
Abstract
(EN)
A method of transmitting uplink control information of a user equipment is provided. The method includes: generating the uplink control information repeatedly as many as a uplink data transmission layer; modulating the uplink control information to generate a plurality of repeated modulation symbol; applying a precoding matrix to the plurality of repeated modulation symbols to generate a plurality of first precoded symbol; and transmitting the plurality of first precoded symbols respectively through a plurality of antennas in an uplink subframe comprising a plurality of single carrier frequency division multiple access(SC-FDMA) symbols in a time domain and a plurality of subcarriers in a frequency domain.

La présente invention concerne un procédé pour transmettre des informations de commande de liaison montante d'un équipement utilisateur. Le procédé consiste : à générer les informations de commande de liaison montante à plusieurs reprises autant de fois qu'une couche de transmission de données de liaison montante; à moduler les informations de commande de liaison montante pour générer une pluralité de symboles de modulation répétés; à appliquer une matrice de précodage sur la pluralité de symboles de modulation répétés pour générer une pluralité de premiers symboles précodés; et à transmettre la pluralité de premiers symboles précodés respectivement à travers une pluralité d'antennes dans une sous-trame de liaison montante qui comprend une pluralité de symboles d'accès multiple par répartition en fréquence à porteuse unique (SC-FDMA) dans un domaine temporel et une pluralité de sous-porteuses dans un domaine de fréquence.
