Abstract:
(EN) A HARQ feedback method for eMTC and a terminal device, used to solve the technical problem in the prior art of, when using multiple HARQ processes, a PUCCH providing feedback to each HARQ process individually, causing high PUCCH resource overhead. A terminal device determining a greatest number of hybrid automatic repeat request HARQ processes the terminal device can call; when a number of individual HARQ processes received reaches said maximum number of HARQ processes, merging the acknowledgment ACK/negative acknowledgment NACK responses of each received HARQ process into a PUCCH of a set format, an ACK/NACK of each HARQ process of the received HARQ processes being expressed by a bit of the PUCCH of the set format; the terminal device sending the merged PUCCH of the set format to a base station.
(FR) La présente invention concerne un procédé de rétroaction HARQ pour eMTC et un dispositif terminal, utilisés pour résoudre le problème technique de l'état de la technique où, lors de l'utilisation de multiples processus HARQ, un PUCCH fournit une rétroaction à chaque processus HARQ individuellement, provoquant un haut surdébit de ressources PUCCH. Ledit procédé comprend : par un dispositif terminal, la détermination d'un plus grand nombre de processus HARQ (demande de répétition automatique hybride) que le dispositif terminal peut appeler ; lorsqu'un nombre de processus HARQ individuels reçus atteint ledit nombre maximum de processus HARQ, le fusionnement des réponses d'accusé de réception ACK/d'accusé de réception négatif NACK de chaque processus HARQ reçu dans un PUCCH ayant un format défini, un ACK/NACK de chaque processus HARQ des processus HARQ reçus étant exprimé par un bit du PUCCH ayant le format défini ; par le dispositif terminal, l'envoi du PUCCH fusionné ayant le format défini à une station de base.
(ZH) 一种针对eMTC的HARQ反馈方法及终端设备,用于解决现有技术中当使用多个HARQ进程时,PUCCH对于每一个HARQ进程都分别进行反馈,会造PUCCH资源开销大的问题。终端设备确定出自身可调用的最大混合自动重传请求HARQ进程数;所述终端设备在接收到的各个HARQ进程达到所述最大HARQ进程数时,将所述接收到的各个HARQ进程的确认应答ACK/否定应答NACK合并成设定格式的PUCCH,其中,所述接收到的HARQ进程中的每个HARQ进程的ACK/NACK使用所述设定格式的PUCCH中的一个比特位表示;所述终端设备将合并后的所述设定格式的PUCCH发送给基站。
