Flow chart, the executive agent of this embodiment is network equipment, such as base station, RNC etc., with in LTE network in the embodiment of the present invention
Base station as a example by the technical program is described, which describe base station adjust IBLER desired value method.As it can be seen, this is real
Execute example to comprise the following steps:
Step 101, determines that the position attribution of user equipment (UE), described position attribution are far point or middle near point.
Wherein, base station be referred to UE average modulation coded system (Modulation and Coding Scheme,
Or MCS filter value or Signal to Interference plus Noise Ratio (Signal to Interference plus Noise Ratio, SINR) MCS)
Etc. parameter, determine the position attribution of UE.
Specifically, if average MCS is less than presetting MCS threshold value, it is determined that UE is far point UE, if average MCS is more than
Or equal to presetting MCS threshold value, it is determined that UE is middle near point UE；If or whether MCS filter value is less than presetting MCS thresholding
Value, it is determined that UE is far point UE, if MCS filter value is more than or equal to presetting MCS threshold value, it is determined that UE is middle near point
UE；If or SINR is less than SINR threshold value, it is determined that UE is far point UE, if SINR is more than or equal to SINR threshold value, then
Determine that UE is middle near point UE.
Wherein, preset MCS threshold value and could be arranged to 4.5, it is also possible to be set to other values, and SINR threshold value is concrete
This can also not limited by value by base station sets itself, the embodiment of the present invention.
In addition to determine the attribute of UE according to average MCS or MCS filter value or SINR etc., other parameters are used
Determine that the method for user property of UE is also in the protection domain of the embodiment of the present invention.
If through judging, determining that UE is far point UE, then perform step 102；If middle near point UE, then perform step
103。
Step 102, if described UE is far point UE, then adjusting an IBLER desired value is the 2nd IBLER desired value, institute
Stating the IBLER desired value that an IBLER desired value is system default, described 2nd IBLER desired value is more than a described IBLER
Desired value.
If UE is far point UE, then can be with lifting IBLER desired value, i.e. adjusting an IBLER desired value is the 2nd IBLER
Desired value, wherein, the 2nd IBLER desired value is more than an IBLER desired value, so retransmits increase, and the MCS just passed just promotes
, and then can realize just passing the lifting of the spectrum efficiency of correspondence, if the lifting just passing the spectrum efficiency brought can make up
Retransmit and increase the loss brought, then lifting IBLER desired value can bring the gain of spectrum efficiency.
Wherein, an IBLER desired value is the IBLER desired value of system default, and usual value is 10%, the 2nd IBLER
Desired value can require to be configured according to system performance index, and in the range of reasonably, the 2nd IBLER desired value is more than first
IBLER desired value, such as a value in 20%～40%, thus can realize the lifting of IBLER desired value.
Step 103, if described UE is middle near point UE, the little transmission block TB block ratio dispatched as described UE is more than or equal to
During preset ratio threshold value, then adjusting a described IBLER desired value is described 2nd IBLER desired value, wherein, and described little TB
Block is that size TBS of transmission block is less than the TB block presetting TBS threshold value.
If UE is middle near point UE, then determine whether whether the little TB block ratio that UE dispatches compares more than or equal to presetting
Example threshold value, i.e. judges whether business scenario is middle near point packet services scene.Here, preset ratio threshold value and default TBS
Threshold value can be by base station sets itself, and the size of value is not limited by the embodiment of the present invention.
If little TB block ratio is more than or equal to preset ratio threshold value, then may determine that business scenario is that middle near point is little
Bag business scenario, now can adjust an IBLER desired value is the 2nd IBLER desired value, it is achieved lifting of IBLER desired value
Rise.
Optionally, before adjusting IBLER desired value, it is also possible to according to CQI information, whether the channel of true described UE is class
Like awgn channel.Wherein, it is judged that whether the channel of described CQI information mark is similar awgn channel, including: described CQI is believed
Breath is mapped as the first spectrum efficiency；Calculate absolute value and the history absolute value of the difference of the first spectrum efficiency and the second spectrum efficiency
Filter value, wherein said second spectrum efficiency is the spectrum efficiency that the CQI information once reported before described UE is corresponding, and history is exhausted
The CQI information received before according to value is calculated；If the sampled value of described filter value is more than presetting filter value door
Limit value, it is determined that the non-similar awgn channel of described channel.Due under the scene that the channel of UE is similar awgn channel, if will
IBLER desired value tunes up, then may cause the negative gain of spectrum efficiency.Therefore, the embodiment of the present invention can be non-similar at channel
Adjust IBLER desired value on the premise of awgn channel, and then realize promoting far point user or middle near point user scheduling decimal
On the basis of effect according to the spectrum efficiency under the business scenario of bag, it is to avoid the situation of negative gain occurs.
Optionally, before adjusting IBLER desired value, it is also possible to be calculated as the meansigma methods of the RB number of UE distribution；And then really
It is set to the meansigma methods of RB number of UE distribution more than presetting RB threshold value.Owing to the meansigma methods at RB number is not more than the RB thresholding preset
In the case of value, if IBLER desired value tuned up, the IBLER desired value that will adjust system default value is second
IBLER desired value, is likely to result in the negative gain of spectrum efficiency.Therefore, the embodiment of the present invention can be more than in the meansigma methods of RB number
Adjust IBLER desired value on the premise of presetting RB threshold value, and then realize promoting far point user or middle near point user scheduling
On the basis of the effect of the spectrum efficiency under the business scenario of small data packets, it is to avoid the situation of negative gain occurs.
Thus, the embodiment of the present invention is determined by the position attribution of UE, and described position attribution is far point or middle near point；If
Described UE is far point UE, then adjusting an IBLER desired value is the 2nd IBLER desired value, and a described IBLER desired value is for being
The IBLER desired value of system acquiescence, described 2nd IBLER desired value is more than a described IBLER desired value；Or, if described
UE is middle near point UE, when the little TB block ratio that described UE dispatches is more than or equal to preset ratio threshold value, then adjusts described the
One IBLER desired value is described 2nd IBLER desired value, and wherein, little TB block is that size TBS of transmission block is less than presetting TBS door
The TB block of limit value.Thus, network equipment can realize self adaptation under far point user's scene and middle near point packet services scene
Adjust IBLER desired value, reach the frequency spectrum promoting under the business scenario of far point user or middle near point user scheduling small data packets
The effect of efficiency.
The self-adapting regulation method of another descending initial block error rate IBLER desired value that Fig. 2 provides for the embodiment of the present invention
Flow chart, the executive agent of this embodiment is base station, which describes in detail base station self-adaptative adjustment far point user or near
The method of the IBLER desired value of some packet services.As it can be seen, this embodiment comprises the following steps:
Step 201, receives the CQI information that UE reports
The terminal being active can constantly report CQI information, so that base station is according to the CQI information business number to UE
According to being scheduling calculating.
Step 202, it is judged that whether channel corresponding to CQI information is similar awgn channel.
Base station is according to the CQI information received, it is judged that the undulatory property on channel time domain identifies channel type, and channel is permissible
For similar awgn channel or non-similar awgn channel.
Wherein, it is judged that whether the channel of described CQI information mark is similar awgn channel, including: described CQI information is reflected
Penetrating is the first spectrum efficiency；Calculate the filter of first spectrum efficiency absolute value with the difference of the second spectrum efficiency and history absolute value
Wave number, wherein said second spectrum efficiency is the spectrum efficiency that the CQI information once reported before described UE is corresponding, history absolute value
The CQI information received before according to is calculated；If the sampled value of described filter value is more than presetting filter value threshold value,
Then determine the non-similar awgn channel of described channel.
Specifically, CQI information can be mapped as the spectrum efficiency of correspondence by base station, and the CQI reported by UE is mapped to correspondence
Spectrum efficiency, the absolute value of the difference of spectrum efficiency calculated for twice before and after then calculating, when receiving CQI information before
The absolute value of the difference of twice spectrum efficiency corresponding for CQI before and after identical method can also be used to calculate, this can become goes through
History absolute value, is filtered with history absolute value the absolute value of the difference of the spectrum efficiency currently calculated, i.e. can be filtered
Wave number, carries out periodic samples, i.e. can get the sampled value of filter value filter value, according to the sampled value judgement of this filter value is
No for similar awgn channel, if the sampled value of i.e. filter value is less than presetting filter value threshold value, then judge UE respective channels
Channel type is similar awgn channel, is otherwise non-similar awgn channel.Wherein, it is mapped as correspondence at the CQI reported by UE
During spectrum efficiency, if UE reports a road CQI, directly this road CQI is mapped to spectrum efficiency；If UE reports two road CQI, will
Spectrum efficiency after every road maps is added summation.Below with UE at the CQI reported for the M time as CQI (M), report for the M-1 time
CQI is the method that base station judges channel type according to CQI information that illustrates as a example by CQI (M-1):
First, CQI is mapped as spectrum efficiency.If UE reports a road CQI, then according to CQI (M, cw1)-> Eff (M),
CQI information CQI (M, cw1) can be mapped as spectrum efficiency Eff (M)；If reporting two road CQI, then according to CQI (M, cw1)-
> Eff (M, cw1), first via CQI information CQI (M, cw1) can be mapped as spectrum efficiency Eff (M, cw1), according to CQI (M,
Cw2)-> Eff (M, cw2), can be mapped as spectrum efficiency Eff (M, cw2) by the second tunnel CQI information CQI (M, cw2), and according to
Eff (M)=Eff (M, cw1)+Eff (M, cw2), calculate two-way CQI information and Eff (M).
Second, the absolute value of the difference of the spectrum efficiency that twice CQI mapping obtains before and after calculating.According to DeltaEff (M)
=| Eff (M)-Eff (M-1) |, can be calculated the absolute value of the difference of twice spectrum efficiency of before and after.
3rd, the DeltaEff calculating second step are filtered operation.Assume that filtering factor is a, then basis
DeltaEffFilter (M)=(1-a) * DeltaEffFilter (M-1)+a*DeltaEff (M), can calculate before and after twice
