Description

The method of statistics of error rate accuracy

Technical field

The present invention relates to mobile communication technology, particularly relate to the method for a kind of statistics of error rate (BLER, BlockError Ratio) precision.

Background technology

In 3-G (Generation Three mobile communication system), power control is an indispensable necessary link in the intercommunication, and described power control comprises inner-loop power control and external circule power control.Described external circule power control is used for base station node B and radio network controller (RNC, Radio Network Controller) the power control between, by Universal Terrestrial Radio Access Network network (UTRAN, Universal Terrestril Radio Access Network) RNC of side finishes, RNC is according to the Block Error Rate (BLER of the user data that measures, Block Error Ratio) changes target signal interference ratio (SIR, Signal-to-Interference Ratio) value, and this value fed back to the base station, to realize uplink power control; And be responsible for the BLER that this UE of statistics receives data in UE side Radio Resource control (RRC, Radio Resources Control), thus adjust the target SIR value, to realize downlink power control.Described inner-loop power control will be adjusted the transmitting power of UE according to the target SIR value that external circule power control provides, thereby realizes power control.The quality of target SIR value adjustment is directly connected to the effect of power control, and the adjustment of target SIR value depends on the statistics of BLER value, no matter be the RNC statistics BLER value of network side, still UE side RRC statistics BLER value all can only be indicated (CRCI by the cyclic redundancy check (CRC) that physical layer reports, Cyclic Redundancy Check Indicator) add up, thus the data check that reports of physical layer as a result CRCI be a very crucial part.

At present, the implementation method according to the data statistics BLER precision that reports has two kinds.

A kind of implementation method of the BLER of statistics precision is to utilize the data after deciphering to carry out CRC check, data after the verification are sent to RRC among the RNC or the RRC among the UE, data and discontinuous emission (DTX for frame losing, Discontinuous Transmission) data under the state are not handled, and directly return the state that receives data again.RRC among the described RNC or the RRC among the UE directly carry data CRCI information is carried out target SIR by the statistics BLER of some cycles adjustment according to receiving in the data.Implementation step is with reference to figure 1:

Step L10: the channel decoding module judges whether the data that receive are special burst (being SpecialBurst), if, then described data are reported RRC among the RNC or the RRC among the UE, and it is masked as special burst, that is to say, frame type with these data of additional character mark is special burst Special Burst, and described Frame is sent to RRC or the RRC among the UE (step L11) among the corresponding RNC; Otherwise, execution in step L12;

The data demodulates detection module judges earlier whether the signal to noise ratio of the data of eating dishes without rice or wine reaches threshold value, detects the validity of data, when detected data are passed through detection threshold, the data after the demodulation is sent to the subsequent communication channel decoding module; Otherwise data do not send.

Described channel decoding module is at first to receiving the combinations of transport formats indication (TFCI that carries in the data, Transport Format Combination Indicator) whether be 0 to judge, when TFCI is 0, the data that expression receives are Special Burst, if be not 0, execution in step L12.

Step L12: judge whether to arrive Transmission Time Interval (TTI, Transmission Time Interval)) ending according to the frame number that receives data; If not, return step L10; If judge whether to exist frame losing (step L13) according to the continuity of receiving data frames in the described TTI number; If there is frame losing, then turns back to and carry out Data Receiving again, be i.e. step L10;

Step L14:, the data that receive are sent into decoder decipher if there is not frame losing;

Step L15: the data after will deciphering are carried out CRC check, the check results that obtains is indicated with CRCI, and Frame is sent to the radio resource control RRC of network side radio network control RNC entity or the radio resource control RRC of user equipment (UE) side;

Step L16: RRC among the described RNC or the RRC among the UE according to the data frame number and the Special Burst frame number that receive, calculate the frame losing number in the time interval of setting;

Step L17: the piece number according to indication check errors among the CRCI that receives adds that the erroneous block number of setting in the frame losing calculates BLER, and this and value are divided by with total block data, obtains the BLER value in this time interval.

In said method, described detected data can not have problems by under the situation of detection threshold value.But, under the very poor situation of channel quality, the data that just might produce the transmission of UE side can't be by the situation of detection threshold, decoder can't start and carry out work at this moment, also can't produce the data after the decoding, more can't carry out CRC check, corresponding frame data just can not be delivered to RRC among the RNC or the RRC among the UE, to such an extent as to just Block Error Rate in this case can't be added up therein when carrying out the BLER statistics.Thereby can't carry out external circule power control accurately, this is because under the very poor situation of channel quality, the target SIR value that external circule power control produces is not also stopping down to adjust situation.

The implementation method of another kind of statistics BLER precision is a kind of processing method of simplifying power control, and its main realization principle is that the cycle of the descending DTX of artificial agreement is 1, and guarantees that each frame all has data to transmit, thereby can accurately know whether frame losing.But the method for artificially arranging the DTX cycle can only be applied to the transmission of downlink data, and the UE side relates to the reason of power saving under normal conditions, must guarantee to have the function of discontinuous transmission, thereby can't guarantee that the cycle of DTX is 1.

By above-mentioned two kinds of methods as can be known, because the influence of communication environment, under certain condition, receiver possibly can't receive the data that send over from transmitter, has just produced frame losing; Simultaneously, in communication process, up-downgoing all can have the DTX state, also can produce transmitting terminal this moment and initiatively not carry out the situation that data send, and receiver also can't receive the data of transmitter in this case.Therefore, the defective that both of these case exists for receiver is identical basically, be that data can't be passed through detection threshold, yet, for this situation, its channel quality is obviously different, but in the prior art scheme, both of these case is not distinguished in physical layer, and do not report respectively at different data, thereby make the RRC of RRC among the RNC of network side or UE side can not calculate the precision of BLER value,, thereby make external circule power control can't reach effect accurately with correct adjustment target SIR value according to different reported datas.

Summary of the invention

The technical problem that the present invention solves provides a kind of method of statistics of error rate accuracy, reporting of the physical layer data of this method by NodeB side or UE side, the RRC or the RRC among the UE that improve among the network side RNC calculate the BLER precision, thereby make external circule power control more accurate.

Embodiment

Core of the present invention is that the data that Radio Link reports are divided into two states, and a kind of is the state (being continuous emission state) that normally reports, and a kind of is discontinuous emission (DTX, DiscontinuousTransmission) state.Under these two kinds of different conditions, respectively Frame is produced different reporting policies, and frame losing in the normal course of communications and the idle data frame that is under the DTX state distinguished, make the cyclic redundancy check (CRC) that reports indicate (CRCI as far as possible, Cyclic Redundancy Check Indicator) can accurately reflect current channel circumstance, thereby guarantee that channel quality can more accurately and timely feed back to RRC among the RNC or the RRC among the UE.RRC among the described RNC or the RRC among the UE directly carry the value that data CRCI information is come statistics of error rate (BLER, Block Error Ratio) by certain Transmission Time Interval according to receiving in the data, to carry out the adjustment of target SIR.Reach basis receives in the time interval of setting data frame number and special burst (Special Burst) frame number, calculate the number of frame losing.Piece number according to indication check errors among the CRCI that receives when calculating BLER adds the erroneous block number of setting in the frame losing, and this and value are divided by with total block data, just can obtain the BLER value in this time interval.

The present invention is described further in conjunction with the accompanying drawings respectively below.

Please refer to Fig. 2, be the flow chart of the method for statistics of error rate accuracy of the present invention, described method is applicable to that the data that report in the Radio Link are continuous data.Described method comprises:

Step S10: judge whether the data receive are special burst, if, then these data are reported RRC among the network side RNC or the RRC among the UE, and it is masked as special burst, finish (step S11); Otherwise, execution in step S12 then;

Step S12: judge whether described data exist frame losing in the Transmission Time Interval of setting;

Step S13: if there is frame losing, then frame losing is reported RRC among the network side RNC or the RRC among the UE, and in the Frame that reports, fill frame losing and indicate;

Step S14: if there is not frame losing, then described data sent to decoder and decipher, and carry out cyclic redundancy check (CRC), indicate CRCI result to be filled in the Frame Protocol cyclic redundancy check (CRC), send to RRC among the RNC or the RRC among the UE;

Step S15: RRC among the described RNC or the RRC among the UE in the time interval of setting according to the assay CRCI statistics of error rate in the reported data.

The method of the invention after Radio Link is set up, with first frame that receives data by decoding after, and be initial by the data block of CRC check, begin to add up the precision of the Block Error Rate of described emission data, its implementation procedure is:

The data that the receiving demodulation detection module sends detect by judging whether combinations of transport formats indication (TFCI, Transport Format Combination Indicator) is 0, judging whether data are special burst (being special burst); If described TFCI is 0, then the data of described detection are special burst, and the data that will contain special burst indication send to the controlled in wireless resource RRC of radio network controller (RNC) side or the controlled in wireless resource RRC of UE side.

If described TFCI is not 0, then described detected data are not special bursts, and then whether continuous according to the data frame number that receives, judge whether the reception data in a Transmission Time Interval (TTI, Transmission Time Interval) of setting exist frame loss condition; If the data frame number that receives is continuous, then received data is delivered to decoder and decipher; And then decode results carried out CRC check, check results is filled in the position at CRCI place in the Frame Protocol, and the Frame that has added CRCI is sent to corresponding entity, be i.e. the RRC of network side RNC entity, the RRC of UE side.

If received data frame number is discontinuous, then there are lost frames in explanation, and this described decoder of delivering to can't be deciphered.For this situation, the data of frame losing should be reported to, promptly in the Frame that reports, all check blocks CRCI as a result are set to entirely 1, produce mistake when representing these data block verifications.Wherein, the transformat that described Frame reports is indicated (TFI, Transport FormatIndicator) value can adopt following dual mode: first kind of mode is that the transformat that keeps correctly reporting is for the last time indicated the TFI value, and the second way is the transformat indication TFI value that adopts the data block number maximum.The mode that reports that is adopted can be selected according to concrete system design.Usually, thinking that the data block transmitted number has under the successional situation, adopting first kind of TFI value mode relatively good; And carry out fast at needs then adopting second kind of tfi value mode relatively good under the situation of outer shroud sir target value adjustment.At last the Frame that has added CRCI is sent to corresponding entity, i.e. the RRC of the RRC of network side RNC entity or UE side.

Such as, if be n at the transformat of the former frame of frame losing, corresponding data piece number is N, then in current frame losing reports, the transformat of this frame also is set to n, and the data block number also is arranged to N, and the check results CRCI with all data blocks is arranged to 1 simultaneously.Give the correct time on the mode of employing maximum data piece number, the transformat during with frame losing is arranged to the pairing transformat of largest block number that current transmission channel may be transmitted, and the check results CRCI with all data blocks is arranged to 1 simultaneously.

The RRC of described network side RNC entity or the RRC of UE side according to the data frame number and the special burst Special Burst frame number that receive, calculate the frame losing number in the time interval of setting.The erroneous block of setting in piece number and the frame losing according to indication check errors among the CRCI that receives is counted sum, is divided by with the total data piece number of described data, counts the value of the interior Block Error Rate of described Transmission Time Interval.

In addition, the present invention also provides a kind of method that improves statistics of error rate accuracy, and this method is applicable to that the detection data that Radio Link reports are the data of discontinuous emission, and its flow chart sees Fig. 3 for details.Described method comprises step:

Step H10: judge whether the data that receive detection are special burst;

Step H11: if not, then described data report handling process same as the prior art, do not repeat them here, finish.

Step H12: if then described Frame is reported RRC among the RNC or the RRC among the UE, and indicate that this frame is a special burst frame, the device of enabling counting simultaneously, the data frame number that accumulative total is received;

Step H13: judge whether the data that next frame receives are special burst;

Step H14: if when the data that receive of next frame are special burst, then counter O reset finishes;

Step H15: if when the data that receive of next frame are not special burst, then the value of counter adds 1;

Step H16: judge in the Transmission Time Interval of described data setting whether have frame losing;

Step H17; If there is frame losing, judge then whether the value of counter reaches thresholding, if reach thresholding, return step H10; Otherwise, return step H12, finish;

Step H18: if there is not frame losing, the data in the described Transmission Time Interval sent to decoder decipher, and carry out CRC check, check results CRCI is filled in the Frame Protocol, send to RRC among the RNC or the RRC among the UE;

Step H19: RRC among the described RNC or the RRC among the UE in the Transmission Time Interval of setting according to the assay CRCI statistics of error rate in the reported data.

The method of the invention is carried out CRC check with first frame that receives data after by decoding after Radio Link is set up, and is initial by the data block of CRC check, begins to add up the precision of described emission data Block Error Rate, and its implementation procedure is:

When data that the receiving demodulation detection module sends, by judging whether combinations of transport formats indication (TFCI, Transport Format Combination Indicator) is 0, judges whether detect data is special burst (being special burst); If TFCI is non-vanishing, then described detected data are not special bursts, and the situation that does not also have frame losing, described data are sent to decoder carry out decoded operation, and to decoding after data carry out CRC check, the check results that obtains is indicated with CRCI, will indicate the data that CRCI indicates then and send to the RRC of network side RNC entity or the RRC of UE side.The implementation procedure of this moment is specifically same as the prior art, here repeats no more.

The RRC of described network side RNC entity or the RRC of UE side according to the data frame number and the special burst Special Burst frame number that receive, calculate the frame losing number in the time interval of setting.The erroneous block of setting in piece number and the frame losing according to indication check errors among the CRCI that receives is counted sum, is divided by with the total data piece number of described data, counts the value of the Block Error Rate in the setting Transmission Time Interval.

If described TFCI is zero, when then described detected data are special burst, at first start a counter, be used for calculating the frame number that receives at this state; Continue to receive the data after the next frame demodulation detects; Judge whether the data that receive are special burst; If the data that receive are special burst, then counter O reset continues to receive the data after the next frame demodulation detects.If the data that receive are not special burst, then the value with counter adds 1, utilizes the frame number that receives data, judges whether that the data that receive have arrived the ending of a TTI.If do not arrive, judge then whether the value of described counter arrives the thresholding of setting, if do not arrive, then return and continue to receive the next frame data.Otherwise turn back to again the data that the receiving demodulation detection module sends.。

If arrive, then, judge in a TTI scope, whether frame losing is arranged according to the continuity of the data frame number that receives, if there is frame losing, judge then whether the value of described counter arrives the thresholding of setting,, then return and continue to receive the next frame data if do not arrive.Otherwise turn back to again the data that the receiving demodulation detection module sends.

If there is not frame losing, the TTI data that then receive are delivered to decoder and are deciphered, and decode results carried out CRC check, check CRC check result, if CRC check is passed through, then decode results and CRC check result add in the Frame, send to the RRC of network side RNC entity or the RRC of UE side, continue the data that the receiving demodulation detection module sends.If CRC check is not passed through, judge whether the value of described counter arrives the thresholding of setting, if do not arrive, then return and continue to receive the next frame data.Otherwise turn back to again the data that the receiving demodulation detection module sends.

Wherein, the field value set of described counter is decided by the up direction DTX period T of system's support, for the cycle be the up DTX state of T, its time that exists free of data to send should be the T-1 frame, thereby this thresholding can be set to T-1.

The RRC of described network side RNC entity or the RRC of UE side basis receives in the time interval of setting data frame number and special burst Special Burst frame number, count the value of setting the Block Error Rate in the Transmission Time Interval, concrete statistic processes here repeats no more as mentioned above.

In addition, the present invention provides a kind of method of statistics of error rate accuracy again, is applicable to that Radio Link reports detected data to be the data of emission continuously and the data of discontinuous emission, and its flow chart sees Fig. 4 for details.Described method comprises step:

Step M10: detect the validity of Radio Link reported data, and testing result is sent to decoder decipher, and to can't on the flag bit on the corresponding physical channel, adding invalid sign by the detection data of detection threshold;

Step M11: the uploaded state that detects data in the Radio Link is divided into continuous emission state and discontinuous emission state according to testing result;

Step M12: first frame was set to starting block by the data block of decoding, CRC check after Radio Link was set up, data to continuous emission state and discontinuous emission state are deciphered respectively accordingly, after the CRC check, and the data of adding the CRCI check results are sent to RRC among the RNC or the RRC among the UE;

Step M13: RRC among the described RNC or the RRC among the UE in the time interval of setting according to assay CRCI statistics of error rate accurately.

Wherein, described in the described step M12 continuously the data of emission state decipher accordingly, after the CRC check, and the data of adding the CRCI check results sent to RRC among the RNC or the performing step of the RRC among the UE comprises:

E) judge whether the data receive detection are special burst, if then these data are reported RRC among the RNC or the RRC among the UE, and it is masked as special burst; Otherwise execution in step f);

F) judge in a Transmission Time Interval, whether to have frame losing according to the data frame number that receives data, if then frame losing is reported RRC among the RNC or the RRC among the UE, and in the Frame that reports, fill frame losing and indicate; Otherwise, described data are sent to decoder decipher, and carry out CRC check, with check results CRCI be filled into Frame Protocol in, send to RRC among the RNC or the RRC among the UE;

G) RRC among the described RNC or the RRC among the UE in the time interval of setting according to the precision of the assay CRCI statistics of error rate in the reported data.

Described frame losing reports, in the Frame that sends, with all check blocks as a result CRCI be changed to the RRC that reports after complete 1 among the RNC or the RRC among the UE, the wherein said mode that reports is: adopt to keep the transformat indicated value that correctly reports for the last time or adopt the maximum transformat indicated value of data block number.

The data of discontinuous emission state described in the described step M12 are deciphered accordingly, after the CRC check, and the data of having added decode results and/or CRCI check results are sent to RRC among the RNC or the detailed process of the RRC among the UE is:

J) judge whether described data exist frame losing in the Transmission Time Interval of setting, if judge then whether the value of counter reaches thresholding, if return step e; Otherwise, return step f, finish; Otherwise, the data in the described Transmission Time Interval are sent to decoder decipher, and carry out CRC check, check results CRCI is filled in the Frame Protocol, send to RRC among the RNC or the RRC among the UE;

K) RRC among the described RNC or the RRC among the UE in the time interval of setting according to the precision of the assay CRCI statistics of error rate in the reported data.

The method of the invention produces different reporting policies to Frame under different conditions, frame losing in the normal course of communications and the idle data frame that is under the DTX state are distinguished, and handle accordingly, make the data that have the CRCI indication report can accurately reflect current channel circumstance as far as possible, thereby guarantee that channel quality can more accurately and timely feed back to RRC among the RNC or the RRC among the UE.The implementation procedure of the method for the invention is:

At first, whether the data demodulates detection module reaches detection threshold value according to the signal to noise ratio of the data of eating dishes without rice or wine, come the validity of check data, when if the signal to noise ratio of detected data can't be passed through detection threshold value, still testing result being sent to follow-up decoder deciphers, and identify on the flag bit of corresponding physical channel and add invalidated identification, so that distinguish reporting of described data.

By the sign on the sign position of difference physical channel the data that reported are distinguished, divided two kinds with the data uploaded state of Radio Link, a kind of is normal uploaded state, and its concrete implementation procedure sees for details above-mentioned shown in Figure 2, here repeats no more; Another kind is the DTX state, and its concrete implementation procedure sees for details above-mentioned shown in Figure 3, here also repeats no more.The RNC that the data of described two states all are reported at network side or the RRC entity of UE side at last.And the RRC entity of the RNC of described network side or UE side, in the time interval of setting, add up the total data block number that receives according to the piece number in the reported data frame, in addition, count the piece number that wherein produces the CRC check mistake according to the CRCI indication of carrying in the receiving data frames, the piece number of mistake divided by total data block number, just can be obtained the BLER value in the interbody spacer at this moment.Just can accurately reflect current channel quality, thereby whether the target SIR value of decision external circule power control needs to adjust.

Under request in person in conjunction with an application example the present invention be described.

Such as, in the base station entity in the RAN system, report mode according to data two kinds of the present invention, in Iub FP frame respectively to Radio Link in detected data report, after the RNC entity receives these Frames,, can accurately calculate user's BLER value according to the method (specifically seeing above-mentioned 0 for details) of statistics BLER precision described in the invention, thereby whether decision carries out the adjustment of exterior ring power control sir target value, to reach the purpose of external circule power control.

The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
