Abstract: 기지국 eNB가채널상태표시에근거하여재전송조건을설정하고상기설정된재전송조건을사용자장비 UE에전송하는단계; 및상기 UE가오류블록을수신하였을때 상기수신된재전송조건과상기 UE의현재채널상태표시를비교하고상기재전송조건이만족될때 재전송을트리거하기위해서상기 eNB에 NACK 시그널링을피드백하는단계를포함하는, 멀티캐스트시스템에서재전송을트리거하는방법이개시된다. 본발명에따른방법은상기 UE가오류블록을수신하였을때 UE가 NACK 시그널링을피드백하는조건을설정함으로써 NACK 시그널링의트리거를제약하는것이다. 그러면업링크채널상의피드백시그널링이제약될것이며재전송확률은 Rel 6 HSDPA에서처럼적합한범위로한정될것이며, 따라서전력에대한효율의최적의비가달성될것이다. 결국, 업링크과부하를회피하기위해서 NACK 시그널링의수가제약된다. 한편, 재전송확률이제한되기때문에전력에대한효율의최적의비가달성될수 있다.

Abstract: The method for triggered repeat in the multicast system includes, the base station eNB sets the repeat condition according to the channel state, and sends the condition to the UE. When the UE receives the block with error, it compares the current channel state indication with the repeat condition received. When the condition is satisfied, the UE sends the NACK signaling to the eNB, so the information can be sent again. So the feedback information in the uplink channel is restricted, and the repeat probability is in the proper scope, and the optimal ratio of the efficiency and the power can be achieved.
Abstract translation: 组播系统中的触发重复的方法包括：基站eNB根据信道状态设置重复条件，并将该条件发送给UE。 当UE接收到错误的块时，将当前信道状态指示与接收到的重复条件进行比较。 当条件满足时，UE向eNB发送NACK信令，从而可以再次发送该信息。 因此上行链路信道的反馈信息受到限制，重复概率在适当的范围内，可以实现效率和功率的最佳比例。
