Abstract: front page image
(EN)The present invention relates to a wireless communication system, and more particularly, to a method and apparatus for uplink multiple input multiple output (MIMO) transmission. A method for performing an uplink MIMO transmission according to one embodiment of the present invention comprises the following steps: transmitting, from a first subframe, a first data block and a second data block through a first HARQ process and a second HARQ process, respectively; receiving, at a second subframe, uplink scheduling control information on the first data block and control information which indicates inactivation of the second data block; setting HARQ feedback information on the second data block to an ACK state; and performing retransmission of the first data block from a third subframe on the basis of the uplink scheduling control information on the first data block. Retransmission of the second data block may not be performed until uplink scheduling control information on the second data block is received.
(FR)La présente invention porte sur un système de communication sans fil et, en particulier, sur un procédé et un appareil de transmission entrée multiple sortie multiple (MIMO) en liaison montante. Un procédé de réalisation d'une transmission MIMO en liaison montante selon un mode de réalisation de la présente invention comprend les étapes suivantes : transmission, à partir d'une première sous-trame, d'un premier bloc de données et d'un second bloc de données par un premier processus HARQ et un second processus HARQ, respectivement ; réception, au niveau d'une deuxième sous-trame, d'informations de commande de planification de liaison montante sur le premier bloc de données et d'informations de commande qui indiquent une inactivation du second bloc de données ; réglage d'informations de rétroaction HARQ sur le second bloc de données à un état ACK ; et réalisation d'une retransmission du premier bloc de données à partir d'une troisième sous-trame sur la base des informations de commande de planification de liaison montante sur le premier bloc de données. Une retransmission du second bloc de données peut ne pas être réalisée jusqu'à ce que des informations de commande de planification de liaison montante sur le second bloc de données soient reçues.
(KO)본 발명은 무선 통신 시스템에 대한 것으로, 보다 구체적으로는 상향링크 MIMO(Multiple Input Multiple Output) 전송 방법 및 장치에 대한 것이다. 본 발명의 일 실시예에 따른 상향링크 MIMO 전송을 수행하는 방법은, 제 1 데이터 블록 및 제 2 데이터 블록을 각각 제 1 및 제 2 HARQ 프로세스를 통하여 제 1 서브프레임에서 전송하는 단계; 제 1 데이터 블록에 대한 상향링크 스케줄링 제어 정보 및 제 2 데이터 블록의 비활성화를 지시하는 제어 정보를 제 2 서브프레임에서 수신하는 단계; 제 2 데이터 블록에 대한 HARQ 피드백 정보를 ACK 상태로 설정하는 단계; 및 제 1 데이터 블록에 대한 상향링크 스케줄링 제어 정보에 기초하여 제 1 데이터 블록의 재전송을 제 3 서브프레임에서 수행하는 단계를 포함하고, 제 2 데이터 블록의 재전송은 제 2 데이터 블록에 대한 상향링크 스케줄링 제어 정보를 수신하기 전에는 수행되지 않을 수 있다.
