Specific embodiment
In order that the purpose of the present invention, technical scheme become more apparent, below in conjunction with the embodiment of the present invention in it is attached
Figure, is clearly and completely described to the technical scheme in the embodiment of the present invention.Based on the embodiment in the present invention, this area
All other embodiment that those of ordinary skill is obtained under the premise of creative work is not made, belongs to protection of the present invention
Scope.
The embodiment of the present invention provides a kind of adaptive transmission methods of PDCCH based on DTX and SINR and device, mainly
By judging that whether BLER-DTX exceedes a reference value that agreement specify deciding whether to raise PDCCH polymerization grades and whether oneself
Adjustment SINR thresholdings are adapted to, by counting SINR value corresponding PDCCH polymerization grades are obtained, decide whether to lower PDCCH polymerizations
Grade, is below described in detail.
Below, a kind of PDCCH Adaptive Transmission sides based on DTX and SINR provided in an embodiment of the present invention are discussed in detail
Method.As shown in figure 1, the step of embodiment includes：
Step 101：ENodeB is counted to DTX and SINR, obtains BLER_DTX and SINR.ENodeB detections DTX is simultaneously
And BLER_DTX is counted, according to the CQI (Channel Quality Indicaion, channel quality is indicated) of UE feedbacks, under statistics
Row SINR.
Step 102：ENodeB determines whether according to BLER_DTX and SINR adjustment polymerization grades and self-adaptative adjustment is lowered
The SINR thresholdings of polymerization grade.
Step 103：ENodeB adjusts polymerization grade and SINR thresholdings.
In embodiment, more specifically flow process is devised on the basis of above-mentioned steps, as shown in Figure 2.
Step 201：ENodeB is detected to UE DTX informations；
ENodeB is detected to DTX information, if receiving DTX, DTX is 1, is otherwise 0.Then to BLER_DTX more
Newly.
Step 202：ENodeB is filtered statistics to BLER_DTX and SINR；
ENodeB is filtered statistics to BLER_DTX and SINR, and BLER_DTX statistical methods are as follows：
BLER_DTX (t)=β × BLER_DTX (t-1)+(1- β) × DTX
If eNodeB receives DTX in t, DTX is 1, is otherwise 0,；BLER_DTX (t-1) is（t-1）Moment calculates
The BLER_DTX statistical values for obtaining；β is forgetting factor.
The statistical method of SINR is as follows：
Sinr_ave (t)=β × Sinr_ave (t-1)+(1- β) × SINR (t)
SINR=min(Sinr_ave(t),SINR(t))
SINR (t) is SINRs of the eNodeB in t, and the CQI fed back by t is obtained, and Sinr_ave (t) is t
SINR filter value, the value needs the filtering statistics for preserving the SINR for the t+1 moment, and β is forgetting factor.In order to ensure
The accuracy of PDCCH decodings, the value for obtaining SINR is the minimum of a value of filtered SINR value and instantaneous SINR value.
Step 203：ENodeB judges whether BLER_DTX is more than agreement a reference value, if meeting the condition, goes to step
Rapid 204；Otherwise, step 205 is gone to；
Judge whether BLER_DTX is more than agreement a reference value, agreement specifies that UE can not correctly solve the probability of PDCCH not
Can exceed that 1%.
Step 204：Current polymerization grade is raised a polymerization grade by eNodeB, and according to current instantaneous SINR value,
SINR thresholdings to lowering polymerization grade do adaptive adjustment.
Because polymerization grade has 1,2,4,8 to have 4 polymerization grades altogether, so need to divide 4 intervals by SINR, altogether
3 SINR thresholdings are needed, corresponding 3 thresholdings of self-adaptative adjustment are needed.If current polymerization grade is 1, polymerization grade is adjusted
Whole is 2, and adaptive adjustment polymerization grade is adjusted to the threshold value of 1 SINR under 2；If current polymerization grade is 2, will be current
Polymerization grade is adjusted to 4, and self-adaptative adjustment polymerization grade is adjusted to 2 SINR threshold values under 4；If current polymerization grade is 4,
Current polymerization grade is adjusted to into 8, self-adaptative adjustment polymerization grade is adjusted to 4 SINR threshold values under 8；If current polymerization grade
For 8, it is not necessary to adjust.SINRs of the instantaneous SINR that rise polymerization grade can be obtained as the two polymerization grades adjustment
Threshold value.
Step 205：ENodeB obtains its filtering statistical value using the polymerization grade after adjustment after the statistics SINR1 seconds；
After eNodeB is to polymerization grade adjustment, may proceed to count BLER_DTX and SINR.In order to count adjustment
Accuracy, eNodeB needs to carry out monitor in real time statistics to BLER_DTX, if BLER_DTX is more than agreement a reference value, to poly-
Close grade real-time adjustment.In order to prevent polymerization grade adjust ping-pong, to polymerization grade raise after, arrange 1 second when
Between it is sluggish, i.e., carry out real-time statistics to SINR within this 1 second time, but SINR is not made to determine whether to lower polymerization grade.1
Just can be determined whether to lower polymerization grade according to SINR now after second.
Step 206：ENodeB obtains corresponding polymerization according to SINR value and the SINR thresholdings after self-adaptative adjustment is obtained
Grade；
Each PDCCH polymerization grade, the interval of one SINR of correspondence.Therefore, 4 polymerization grades are to there is 4
Interval, 3 thresholdings, according to the adaptive adjustment thresholdings of instantaneous SINR for raising polymerization grade.
3 thresholdings, ThSINRAl1AndAl2, ThSINRAl2AndAl4, ThSINRAl4AndAl8 can be set.If
SINR>ThSINRAl1AndAl2, then AL (Aggregation Level, polymerization grade)=1;If ThSINRAl2AndAl4<
SINR<ThSINRAl1AndAl2, then AL=2;If ThSINRAl4AndAl8<SINR<ThSINRAl2AndAl4, then AL=4;
If SINR<ThSINRAl4AndAl8, then AL=8;
Due to the CQI accuracys that UE is reported it is not high, in order to ensure UE can correctly solve PDCCH carrying information, so
Δ SINR has been done from the threshold value for being transferred to hour greatly to AL（SINR amount trimmeds）Adjustment be：If SINR+ is Δ SINR>
ThSINRAl1AndAl2, then AL=1;If ThSINRAl2AndAl4<SINR+ΔSINR<ThSINRAl1AndAl2, then AL=
2;If ThSINRAl4AndAl8<SINR+ΔSINR<ThSINRAl2AndAl4, then AL=4;If SINR+ is Δ SINR<
ThSINRAl4AndAl8, then AL=8.
ThSINRAl1AndAl2, ThSINRAl2AndAl4, ThSINRAl4AndAl8 this 3 thresholdings can basis respectively
Corresponding AL is adjusted to 8 instantaneous SINR from 1 instantaneous SINR, AL for being adjusted to 2 from the 2 instantaneous SINR and AL for being adjusted to 4 from 4
Adaptive adjustment.
Step 207：Determined to lower or uncomfortable polymerization grade according to the polymerization grade；
Corresponding polymerization grade is obtained according to 206, if the polymerization grade is equal to current polymerization grade, need not be to this
Polymerization grade is adjusted, and polymerization grade of the polymerization grade as after now adjusting otherwise will be obtained in 206.
