Abstract: front page image
(EN)The present invention relates to the field of communications, and discloses an enhanced physical downlink control channel (E-PDCCH) transmission method and device, the E-PDCCH comprising at least one E-PDCCH element. The method comprises: mapping at least one E-PDCCH element onto the pre-configured position of at least one resource block pair, the size of the resources of each resource block pair being greater than or equal to the size of the resources of two E-PDCCH elements, and the resources in the resource block pair used by each E-PDCCH element being parts of the resources of each resource block of the resource block pair; transmitting the E-PDCCH on the time frequency resources mapped in the resource block pair. The present invention produces enhanced PDCCH functionalities while fully utilizing time frequency resources.
(FR)La présente invention concerne le domaine des communications, et porte sur un procédé et un dispositif de transmission de canal de commande de liaison descendante physique amélioré (E-PDCCH), l'E-PDCCH comprenant au moins un élément E-PDCCH. Le procédé consiste à : mapper au moins un élément E-PDCCH à la position préconfigurée d'au moins une paire de blocs de ressources (RB), la dimension des ressources de chaque paire de blocs de ressources étant supérieure ou égale à la dimension des ressources de deux éléments E-PDCCH, et les ressources de la paire de blocs de ressources utilisée par chaque élément E-PDCCH constituant des parties des ressources de chaque bloc de ressources de la paire de blocs de ressources; transmettre l'E-PDCCH sur les ressources temps-fréquence mappées dans la paire de blocs de ressources. La présente invention produit des fonctionnalités d'E-PDCCH améliorées tout en utilisant entièrement des ressources temps-fréquence.
(ZH)本发明涉及通信技术领域,公开了一种增强的物理下行控制信道 E-PDCCH的传输方法及设备,所述 E-PDCCH包括至少一个 E-PDCCH单位,所述方法包括:将所述至少一个 E-PDCCH单位映射到至少一个资源块对中的预定位置,其中,每个所述资源块对的资源大小大于或者等于两个 E-PDCCH5 单位所占的资源大小,每个 E-PDCCH单位在所述资源块对中所占据的资源包括所述资源块对中每个资源块的部分资源;在所述资源块对中映射的时频资源上传输所述 E-PDCCH。利用本发明,可以在充分利用时频资源的情况下,获得较好的增强的 PDCCH性能。
