1. the retransmission confirmation information feedback method in multicarrier system, is characterized in that, comprising:

  • User equipment (UE) receives multiple downlink data packet that base station sends, and generation corresponds respectively to described multiple downlink data packetM retransmission confirmation information, wherein said M is greater than 4;

    Described UE is divided into k group according to rule of classification by a described M retransmission confirmation information, and according to retransmission confirmation information and available anti-The mapping relations of feedback channel number, feedback information, determine the k group available feedback that corresponds respectively to described k group retransmission confirmation informationChannel number and feedback information;

    Described UE is the described available feedback channel volume in k feedback channel of a sub-frame of uplink by described k group feedback informationOn number, send to described base station,If the number of described multiple downlink data packet is less than or equal to the number N of the available uplink feedback channel of 4 times, described heavyPass the number that confirmation number M equals described multiple downlink data packet;

    If the number of described downlink data packet is greater than 4N, to described multiple downlink data packet, corresponding multiple re-transmissions are confirmedInformation merges processing, generates a described M retransmission confirmation information, so that M is less than or equal to 4N,Wherein, described rule of classification comprises according to feedback resources number reserved in each uplink feedback channel and determines described k groupNumber p1, the p2 of each group in retransmission confirmation information ... pk, andItsDescribed in p1, p2 ... pk is less than or equal to 4.
