Title
(EN) MOBILE TERMINAL AND BASE STATION INVOLVED IN DOWNLINK CHANNEL OPERATIONS
(FR) TERMINAL MOBILE ET STATION DE BASE IMPLIQUÉS DANS DES OPÉRATIONS DE CANAL DE LIAISON DESCENDANTE
Abstract
(EN)
The present disclosure relates to a mobile terminal, a base station and respective operation methods. The mobile terminal comprises circuitry, which in operation assumes that a base station is configured to use one of a plurality of transmission beams, receives a downlink control channel candidate and a corresponding demodulation reference signal using one of a plurality of reception beams corresponding to the assumed one of the plurality of transmission beams, performs channel estimation based on the received demodulation reference signal, and, depending on the quality, demodulates the downlink control channel candidate using the channel estimation. The channel estimation is performed using a demodulation reference signal sequence which is generated observing an association which is associating the generated sequence with the assumed one of the plurality of transmission beams such that at least two of the plurality of transmission beams are associated with different demodulation reference signal sequences.

La présente invention concerne un terminal mobile, une station de base et des procédés respectifs d'exploitation. Le terminal mobile comporte une circuiterie qui, en cours de fonctionnement, suppose qu'une station de base est configurée pour utiliser un faisceau parmi une pluralité de faisceaux d'émission, reçoit un canal candidat de commande de liaison descendante et un signal de référence de démodulation correspondant en utilisant un faisceau parmi une pluralité de faisceaux de réception correspondant au faisceau supposé de la pluralité de faisceaux d'émission, effectue une estimation de canal d'après le signal de référence de démodulation reçu, et, en fonction de la qualité, démodule le canal candidat de commande de liaison descendante en utilisant l'estimation de canal. L'estimation de canal est effectuée en utilisant une séquence de signaux de référence de démodulation qui est générée en observant une association qui associe la séquence générée au faisceau supposé de la pluralité de faisceaux d'émission de telle façon qu'au moins deux faisceaux de la pluralité de faisceaux d'émission soient associés à des séquences différentes de signaux de référence de démodulation.
