1. the method sending the state report of PDCP PDCP layer in mobile communication system, by receivingThe state of volume of data is reported that in the method being sent to transmitting terminal PDCP layer, the method comprises the following steps by end PDCP layer:

  • Determined the reception state of described volume of data by described receiving terminal PDCP layer, wherein, described volume of data is PDCPService data unit SDU;

    Generated the receiving state report of described PDCP SDU by described receiving terminal PDCP layer, this receiving state report indicates whetherIn each data that described receiving terminal PDCP layer is successfully received in described volume of data;

    AndBy described receiving terminal PDCP layer, described receiving state report is sent to described transmitting terminal,Wherein, send described receiving state report with the form of PDCP control protocol data cell PDU,Wherein, described receiving state report includes data/control D/C field, controls PDU type field, LSN field or FSN wordSection and bitmap field, described LSN field includes and the sequence number SN information of the PDCP SDU that last is corresponding in bitmap field, andAnd described FSN field includes the sequence number SN information of the PDCP SDU corresponding with in bitmap field first, described bitmap field bagInclude and indicate at least one PDCP SDU described at least one the PDCP SDU indicated by described LSN field or FSN fieldAt least one designator of reception state, each designator indicates the reception of corresponding PDCP SDU to be success or failure,AndWherein, by according to described PDU type field, described LSN field or FSN field and the secondary ordered pair of described bitmap fieldThese fields arrange, and construct described receiving state report.
