Table 2
In this step, can in sending to the measurement control signaling of UE, dispose BLER by the RNC of network side less than the pairing cell parameters of reporting events of setting thresholding, the cell parameters of promptly corresponding 5B reporting events.
For example,, can in measuring the control signaling, dispose CRC check sign indicating number sum and crc error check code sum for the DCH channel, further, also configurable delay triggering times.
And for example, for the HS-DSCH channel, can be in measuring the control signaling the total transmission block sum of configuration HS-DSCH, HS-DSCH retransmit the formation label that the correct piece sum in back, HS-DSCH retransmit back erroneous block sum and need to measure, further, also configurable delay triggering times.
In addition, when the 5A reporting events also supported in the embodiment of the invention HS-DSCH, if simultaneously to giving the correct time on HS-DSCH use 5A incident and the 5B incident, correct piece sum can be same value after wherein total transmission block sum of the HS-DSCH of 5A incident and 5B incident and HS-DSCH retransmitted, and this moment, network side also needed to dispose the cell parameters of corresponding 5A reporting events in sending to the measurement control signaling of UE.
Afterwards, the measurement control signaling that disposes above-mentioned cell parameters is sent to UE, be used for indicating UE the down channel of appointment to be carried out the BLER measurement of described cell parameters appointment, and when the thresholding that measurement result is set in less than described cell parameters, carry out BLER and report, carry out BLER when perhaps measurement result is less than the thresholding set in the described cell parameters within the number of times of appointment in cell parameters continuously and report.
In this step, UE can be according to the measurement control signaling from network side, parse the cell parameters of corresponding 5B reporting events wherein, according to described cell parameters, the down channel of appointment is carried out the BLER measurement of appointment in the described cell parameters, and when the thresholding that measurement result is set in less than described cell parameters, carry out BLER and report, carry out BLER when perhaps measurement result is less than the thresholding set in the described cell parameters within the number of times of appointment in cell parameters continuously and report.
For example, for the DCH channel, UE can measure the CRC check sign indicating number of the DCH that receives, when the CRC check sign indicating number that receives reaches described CRC check sign indicating number sum, whether judgement crc error check code wherein is less than described crc error check code sum, if then carry out BLER and report.
Perhaps, if comprise the delay triggering times in the cell parameters, then UE judges whether that continuously the crc error check code is less than crc error check code sum, if then carry out BLER and report in postponing triggering times.
During specific implementation, UE can be provided with the communication quality counter that improves, and for example, is labeled as the 5B-Triger_number counter, and this counter of initialization is zero, carries out following operation afterwards:
A) when the descending CRC check yardage of receiving equals Total CRC Number (the being CRC check sign indicating number sum) parameter of network side regulation, do as acting:
If i. wherein wrong CRC number during less than Total CRC Number (the being CRC check sign indicating number mistake sum) parameter of network side regulation, adds up 1 to 5B-Triger_number;
If ii. wherein wrong CRC number is during greater than the Total CRC Number parameter of network side regulation, to the 5B-Triger_number zero clearing.
B) if 5B-Triger_number greater than the TRIGER Number parameter of network side regulation, portable terminal reports by measurement report and downlink communication quality takes place " " incident (being the 5B incident) improves.
C) if 5B-Triger_number less than the TRIGER Number parameter of network side regulation, portable terminal keeps other parameter constant.
And for example, for the HS-DSCH channel, UE can the formation label, as the unit of Queue ID for measuring and reporting, with residual BLER (below be labeled as rBLER) is the benchmark of measuring and reporting, to the HS-DSCH label that receives is that the HARQ transmission block of the Queue ID in the cell parameters is measured, when the HARQ transmission block that receives equals the total transmission block sum of described HS-DSCH, judge that whether rBLER retransmits the value of back erroneous block sum/(HS-DSCH retransmits back erroneous block sum+HS-DSCH and retransmits the correct piece sum in back) less than HS-DSCH, if then carry out BLER and report.
Perhaps, if comprise the delay triggering times in the cell parameters, then UE judges whether that continuously in postponing triggering times rBLER retransmits the value of back erroneous block sum/(HS-DSCH retransmits back erroneous block sum+HS-DSCH and retransmits the correct piece sum in back) less than HS-DSCH, if then carry out BLER and report.
In addition, when the 5A reporting events also supported in the embodiment of the invention HS-DSCH, UE can be further when the HARQ transmission block that receives reaches the total transmission block sum of described HS-DSCH, judge that whether rBLER retransmits the value of back erroneous block sum/(HS-DSCH that is used for the 5A incident retransmits back erroneous block sum+HS-DSCH and retransmits the correct piece sum in back) greater than the HS-DSCH that is used for the 5A incident, if the BLER that then carries out the 5A incident reports.
For example, when the HARQ number of transport blocks that receives equals Total HS-DSCH TB Number parameter, can following assessment rBLER:
If i. rBLER＞Bad HS-DSCH TB Number After HARQ For 5A/ (BadHS-DSCH TB Number After HARQ For 5A+Correct HS-DSCH TB NumberAfter HARQ) then reports the 5A incident;
If ii. rBLER＜Bad HS-DSCH TB Number After HARQ For 5B/ (BadHS-DSCH TB Number After HARQ For 5B+Correct HS-DSCH TB NumberAfter HARQ) then reports the 5B incident;
Iii. otherwise do not report.
