Then, the base station determines a closed-loop spatial multiplexing transmission scheme in which the two codewords can be used according to channel conditions, received signal quality, resource allocation, receiver, and the like. For two transmit antennas, the spatial multiplexing of the two codewords corresponds to full rank transmission, so its precoding matrix is an identity matrix, and the DCI format 0D with only one bit of minimum PMI is sufficient to transmit the information of the transmission scheme. Therefore, the base station transmits DCI format 0D in the user-specific search space.

Abstract

Dans la présente invention, plusieurs modes de transmission en liaison montante pour des situations spécifiques sont fournis sous la forme d'une combinaison ou relation de correspondance raisonnable de systèmes de transmission, de formats d'informations de commande de liaison descendante (DCI) et d'espaces de recherche de décodage aveugle limités. Un procédé de transmission pour un canal partagé de liaison montante physique (PUSCH) est décrit dans la présente invention, qui comprend les opérations suivantes : côté station de base, envoyer un message à l'équipement utilisateur pour l'informer du mode de transmission en liaison montante devant être utilisé ; sélectionner le format DCI dans le mode de transmission en liaison montante conformément à la relation de correspondance ; envoyer les DCI dans le format déterminé à l'équipement utilisateur ; côté équipement utilisateur, recevoir le message provenant de la station de base pour apprendre le mode de transmission en liaison montante devant être utilisé ; rechercher le format DCI correspondant au mode de transmission en liaison montante dans l'espace de recherche correspondant au mode de transmission en liaison montante afin de décoder les DCI, déterminant ainsi le système de transmission de PUSCH ; conformément aux informations de commande contenues dans les DCI décodées, et sur la base du système de transmission déterminé, envoyer le PUSCH. Dans chaque mode de transmission en liaison montante, il suffit à l'équipement utilisateur de surveiller les formats DCI limités sur le canal de commande de liaison descendante physique (PDCCH). En conséquence, la complexité du décodage aveugle est réduite. De plus, pour différents systèmes de transmission, conformément à différents nombres de couches, différentes tailles de livre de codes et analogues, avec différents formats DCI, le coût de signalisation est réduit. En outre, par désignation du système de transmission inclus dans le mode de transmission, la flexibilité de planification est possible. La présente invention porte également sur un système de transmission pour canal partagé de liaison montante physique.
