1. a HARQ remained error detection method, is characterized in that, comprising:

  • When transmitting terminal mixed automatic retransfer HARQ layer receives the NACK feedback information of former data, and described transmitting terminal HARQ layer self is determined in the time of need to stopping the re-transmission of former data due to specific reasons, the process that the utilization of described transmitting terminal HARQ layer sends former data sends new data, and send the control signal that described new data is corresponding, new data indication NDI by control signal represents that the NACK that transmitting terminal HARQ layer receives former data feeds back, but transmitting terminal HARQ layer has sent the state information of new data, wherein, set up the corresponding relation of NDI numerical value and new data sequence NDSN, transmitting terminal HARQ layer is when sending data, record the NDSN corresponding to data of this transmission, described NDSN is according to the mode of increasing or decreasing, on the basis of the NDSN of the data of last time transmission, calculate, transmitting terminal HARQ layer is searched corresponding NDI according to the NDSN corresponding to data of this transmission of recording, explicit carrying in the control signal that described NDSN does not send at transmitting terminal,Receiving terminal HARQ layer, according to described state information, detects NACK/ACK residual error does not occur, but transmitting terminal HARQ layer has sent new data, described new data is carried out to reception &

    disposal.
