Abstract
(EN)
Bias in the reception quality between space streams to a plurality of terminal devices is suppressed during the transmission of multi user Multiple Input Multiple Output (MIMO). Disclosed is a wireless communication device for performing spatial multiplexing transmission to a plurality of terminal devices, which is provided with: an additional data area setting unit for allocating part of a resource allocation area to which the data addressed to each of the plurality of terminal devices is not allocated as an additional data area among resource allocation areas for performing the spatial multiplexing transmission, which are allocated to each of the plurality of terminal devices; an additional data generating unit for generating additional data corresponding to the additional data area allocated by the additional data area setting unit; and transmission units for transmitting the data addressed to each of the plurality of terminal devices and the additional data.

Une déviation de la qualité de réception entre des trains spatiaux vers une pluralité de dispositifs terminaux est supprimée au cours d'une transmission multi-utilisateurs à entrées multiples et à sorties multiples (MIMO). Cette invention se rapporte à un dispositif de communication sans fil destiné à exécuter une transmission à multiplexage spatial vers une pluralité de dispositifs terminaux, doté des éléments suivants : une unité d'établissement de zone de données supplémentaires destinée à attribuer une partie d'une zone d'attribution de ressource vers laquelle les données adressées à chacun de la pluralité de dispositifs terminaux ne sont pas attribuées comme une zone de données supplémentaires parmi les zones d'attribution de ressource pour exécuter la transmission à multiplexage spatial, qui sont attribuées à chacun de la pluralité de dispositifs terminaux ; une unité de génération de données supplémentaires destinée à générer des données supplémentaires qui correspondent à la zone de données supplémentaires attribuée par l'unité d'établissement de zone de données supplémentaires ; et des unités de transmission destinées à transmettre les données adressées à chacun de la pluralité de dispositifs terminaux et les données supplémentaires.
