Title (EN) INDICATION METHOD AND APPARATUS OF DOWNLINK TRANSMISSION MODE
(FR) PROCÉDÉ D'INDICATION ET APPAREIL DE MODE DE TRANSMISSION DE LIAISON DESCENDANTE
(ZH) 一种下行传输方式的指示方法及装置
Abstract:
(EN) An indication method of a downlink transmission mode. The indication method includes: a base station carries Downlink Control Information (DCI) in a physical downlink control channel and transmits them to a terminal, wherein, the downlink transmission mode is indicated by an indicating signaling or by the amount of enabled transmitting blocks and the indication signaling in the downlink control information. An indication apparatus of a downlink transmission mode is also provided. The above method and apparatus can support such transmission modes as double-layer transmission, single layer transmission and transmission diversity, indicate the selecting of transmission mode by specific signaling, and ensure the integrality and backward compatibility of downlink transmission mode and its corresponding DCI Format.
(FR) L'invention porte sur un procédé d'indication d'un mode de transmission de liaison descendante. Le procédé d'indication comprend : le transport par une station de base d'informations de commande de liaison descendante (DCI) dans un canal de commande de liaison descendante physique et leur transmission à un terminal, le mode de transmission de liaison descendante étant indiqué par une signalisation d'indication ou par la quantité de blocs de transmission activés et la signalisation d'indication dans les informations de commande de liaison descendante. La présente invention porte également sur un appareil d'indication de mode de transmission de liaison descendante. Le procédé et l'appareil ci-dessus peuvent accueillir des modes de transmission tels qu'une transmission double couche, une transmission simple couche et une diversité de transmission, indiquer la sélection d'un mode de transmission par une signalisation spécifique, et assurer l'intégralité et la compatibilité vers le bas du mode de transmission de liaison descendante et son format DCI correspondant.
