Description
Technical field
The present invention relates to the communications field, particularly a kind of method and device of processing HARQ feedback bits.
Background technology
At LTE(Long Term Evolution, Long Term Evolution) in system, in order to make network side, can accurately grasp the data receiving state of end side, UE(User Equipment, user terminal) need to be in the ACK/NACK information (ack/nack response message) of the corresponding a plurality of descending sub frames of same sub-frame of uplink internal feedback, also referred to as HARQ(Hybrid Automatic Repeat Reuqest, mixed automatic retransfer request) feedback information.
In 3GPP36.213R880 agreement, stipulate, current UE adopts the ACK/NACK Multiplexing(multiplexing) during mode transfer HARQ feedback information, adopt PUCCH(Physical Uplink Control Channel, Physical Uplink Control Channel) carry this HARQ feedback information; Be limited to the transmission means of PUCCH, on PUCCH, conventionally only support the HARQ feedback of 2 bits, therefore the HARQ feedback information of corresponding a plurality of descending sub frames need obtain the HARQ feedback bits of 2 bits through certain mapping, is called b (0), b (1), then transmit by PUCCH.
Conventionally parameters M in system, need to carry out the descending sub frame quantity of HARQ feedback for characterizing UE at same sub-frame of uplink, and for different uplink-downlink configuration and sub-frame of uplink, the value of M is different.For example, consult shown in table 1, table 2 and table 3, represent that respectively M value is 2,3 and at 4 o'clock, the HARQ feedback information of configuration and the mapping relations between HARQ feedback bits, and the numbering that sends the PUCCH that HARQ feedback bits adopts.
Table 1(M=2)
Table 2(M=3)
Table 3(M=4)
As shown in table 3, when M=4, eNB(Evolved Node B, evolved base station)
on the b (0) that receives, b (1) is " 1,0 ", or
on receive b (0), when b (1) is " 0,1 ", after, all there is ambiguity in its corresponding HARQ feedback information, i.e. between b (1) and HARQ feedback information, there are the mapping relations of one-to-many in b (0).For example, consult shown in table 4, b (0), the HARQ feedback information that b (1) " 1,0 " is corresponding is " ACK; ACK, ACK, NACK/DTX ", " ACK, ACK, NACK/DTX; ACK " and " ACK, ACK, NACK/DTX, NACK/DTX ", and b (0), the HARQ feedback information that b (1) " 0,1 " is corresponding is " ACK, NACK/DTX; ACK, ACK ", " NACK/DTX, ACK, ACK; ACK " and " NACK/DTX, NACK/DTX, ACK, ACK ".
Table 4
Under prior art, when HARQ feedback information corresponding to HARQ feedback bits receiving as eNB exists ambiguity, eNB cannot determine the descending sub frame reception condition of UE, cannot judge that UE has correctly received several descending sub frames.In order to guarantee systematic function, current common way is directly by a plurality of HARQ feedback informations corresponding to HARQ feedback bits, characterizes a poorest HARQ feedback information of UE reception as the feedback result of final reception.For example, consult shown in table 5, as the b (0) receiving, when b (1) is " 1,0 ", confirm that the HARQ feedback information receiving is " ACK; ACK; NACK/DTX, NACK/DTX ", exists two to receive wrong descending sub frames in the descending sub frame that sign UE receives, and as the b (0) receiving, when b (1) is " 0,1 ", confirm that the HARQ feedback information receive is " NACK/DTX; NACK/DTX; ACK, ACK ", characterize equally in the descending sub frame that UE receives and exist two to receive wrong descending sub frames.Accordingly, eNB can be for confirming that receiving two wrong descending sub frames carries out data re-transmission.
Table 5
Yet in fact, UE receives wrong descending sub frame probably only one, so, eNB carries out data re-transmission according to the poorest situation of reception for occurring to receive two wrong descending sub frames, just increased to a great extent the misjudged probability of descending sub frame, and the number of retransmissions that has increased descending sub frame, serious waste interface-free resources.

Consult shown in table 6, in the embodiment of the present invention, first will preset HARQ feedback bits b (0), b (1), HARQ feedback information, and the mapping relations of eating dishes without rice or wine between credit rating, specific as follows:
Table 6
As shown in table 6, mapping to b (0), b (1) " 1; 0 " HARQ feedback information in, " ACK, ACK; ACK; NACK/DTX " and " ACK, ACK, being numbered 1. of the credit rating of eating dishes without rice or wine that NACK/DTX is corresponding; " ACK, ACK, NACK/DTX, NACK/DTX " being numbered 2. of the corresponding credit rating of eating dishes without rice or wine; Meanwhile, mapping to b (0), b (1) " 0; 1 " HARQ feedback information in, being numbered 1. of the credit rating of eating dishes without rice or wine that " ACK, NACK/DTX; ACK, ACK " and " NACK/DTX, ACK; ACK; ACK " is corresponding, and being numbered 2. of the credit rating of eating dishes without rice or wine corresponding to " NACK/DTX, NACK/DTX; ACK, ACK "; In the present embodiment, the credit rating of eating dishes without rice or wine be numbered 1. time, represent that the current credit rating of eating dishes without rice or wine is for " good "; The credit rating of eating dishes without rice or wine be numbered 2. time, represent that the current credit rating of eating dishes without rice or wine is for " generally " or " poor ".
Based on above-mentioned mapping relations, to consult shown in Fig. 2, in the embodiment of the present invention, the detailed process of the HARQ feedback bits that the eat dishes without rice or wine quality treatment UE of eNB based on UE sends is as follows:
Step 200:eNB receives the HARQ feedback bits that UE sends on PUCCH channel.
Step 210:eNB determines the current credit rating of eating dishes without rice or wine based on the current data transmit-receive state of UE.
In the embodiment of the present invention, execution step 210 o'clock, can receive the Block Error Rate (BLER) of number and the spectrum efficiency of network side is determined the current credit rating of eating dishes without rice or wine according to UE.
In the dispatching patcher of actual LTE, the CSI(channel condition information that eNB adopts the Block Error Rate of UE to report UE conventionally) revise, and in next dispatching cycle, be UE distributing radio resource according to amended CSI, wherein, CSI comprises CQI(channel quality information), PMI(pre-coding matrix indication) and RI(order indicate); And the spectrum efficiency of network side (also referred to as output spectrum efficiency) normally obtains based on the revised CQI of UE.This shows, the Block Error Rate of eNB based on UE and the spectrum efficiency of network side judge that the current credit rating of eating dishes without rice or wine is very reliable.In the present embodiment, based on above-mentioned Block Error Rate and spectrum efficiency, be provided with following parameter:
BLER_High_Threshold, for judging the Block Error Rate high threshold of the current credit rating of eating dishes without rice or wine, when the Block Error Rate of UE is during higher than this thresholding, confirms that the current credit rating of eating dishes without rice or wine is for " poor ";
BLER_Low_Threshold: for judging the Block Error Rate low threshold of the current credit rating of eating dishes without rice or wine, when the Block Error Rate of UE is during lower than this thresholding, confirm that the current credit rating of eating dishes without rice or wine is for " good ".
Eff_High_Threshold: for judging the spectrum efficiency high threshold of the current credit rating of eating dishes without rice or wine, when the spectrum efficiency of UE is during higher than this threshold value, confirm that the current credit rating of eating dishes without rice or wine is for " good ";
Eff_Low_Threshold: for judging the spectrum efficiency low threshold of the current credit rating of eating dishes without rice or wine, when the spectrum efficiency of UE is during lower than this threshold value, confirm that the current credit rating of eating dishes without rice or wine is for " poor ".
MCS_BLER (i): the Block Error Rate of UE in current i scheduling interval;
MCS_eff
out(i): in current i scheduling interval, carry out the revised spectrum efficiency of CQI.
When above-mentioned each parameter is set, in order to reduce the erroneous judgement of eNB, the thresholding of Block Error Rate and the thresholding of spectrum efficiency should strictly limit, for example, the high threshold that it has been generally acknowledged that the Block Error Rate of UE be arranged on 10% with interior be acceptable, corresponding, it is 1% comparatively reasonable that the low threshold of Block Error Rate is set to.In like manner, preferably, the high threshold of spectrum efficiency is set to 5.1152(CQI Index=14), the low threshold of spectrum efficiency is set to 0.8770(CQI Index=5) more reasonable.
Based on above-mentioned parameter, in the present embodiment, according to UE, receive the Block Error Rate of data and the spectrum efficiency of network side and determine that current eating dishes without rice or wine during credit rating, comprising:
If, MCS_BLER (i) <BLER_Low_Threshold,
And Mcs_eff
out(i) >Eff_High_Threshold, confirms that the current credit rating of eating dishes without rice or wine is for " good ", and 1. the credit rating of eating dishes without rice or wine shown in corresponding table 6 numbers;
If MCS_BLER (i) is >BLER_High_Threshold,
And Mcs_eff
out(i) <Eff_Low_Threshold, confirms that the current credit rating of eating dishes without rice or wine is for " poor ", and 2. the credit rating of eating dishes without rice or wine shown in corresponding table 6 numbers;
If do not meet above-mentioned two situations, confirm that the current credit rating of eating dishes without rice or wine is that 2. the credit rating of eating dishes without rice or wine shown in " generally " corresponding table 6 numbers.
In practical application, when the current credit rating of eating dishes without rice or wine is " poor " and " generally ", also can adopt the different credit rating numberings of eating dishes without rice or wine to represent, in the present embodiment, adopt same reference numeral only for giving an example.
Step 220:eNB, according to the mapping relations between default HARQ feedback bits, the credit rating of eating dishes without rice or wine and HARQ feedback bits, determines the HARQ feedback information corresponding with the HARQ feedback bits receiving and the current credit rating of eating dishes without rice or wine.
Step 230:eNB carries out corresponding data re-transmission according to the HARQ feedback information obtaining.
For example, if the b (0) that eNB receives, b (1) be " 1,0 ", and while confirming the current credit rating of eating dishes without rice or wine for " good ", adopt eat dishes without rice or wine credit rating numbering 1. the HARQ feedback information of correspondence carry out data re-transmission;
If the b (0) that eNB receives, b (1) be " 1,0 ", and while confirming the current credit rating of eating dishes without rice or wine for " generally ", adopts the credit rating of eating dishes without rice or wine to number the 2. HARQ feedback information of correspondence and carry out data re-transmission;
If the b (0) that eNB receives, b (1) be " 1,0 ", and while confirming the current credit rating of eating dishes without rice or wine for " poor ", adopts the credit rating of eating dishes without rice or wine to number the 2. HARQ feedback information of correspondence and carry out data re-transmission;
Wherein, if determining the HARQ feedback information corresponding with the HARQ feedback bits receiving and the current credit rating of eating dishes without rice or wine, eNB has at least two kinds, as, consult shown in table 6, suppose the b (0) that eNB receives, b (1) is " 1, 0 ", and confirm that the current credit rating of eating dishes without rice or wine is for " good ", the credit rating of now the eating dishes without rice or wine numbering 1. HARQ feedback information of correspondence has " ACK, ACK, ACK, NACK/DTX " and " ACK, ACK, NACK/DTX, ACK " two kinds (also can arrange two or more, herein only for giving an example), so, can be considered as these at least two kinds of HARQ feedback informations and still have ambiguity, and this is had to choosing of ambiguous HARQ feedback information is equivalent (being that probability of happening is suitable), eNB can adopt exploration selection mode, as, eNB can select a kind of HARQ feedback information to carry out data re-transmission at random, also can be according to the priority setting in advance, select the highest a kind of HARQ feedback information of current priority to carry out data re-transmission.
Based on above-described embodiment, in practical application, if determining the HARQ feedback information corresponding with the HARQ feedback bits receiving and the current credit rating of eating dishes without rice or wine, eNB has at least two kinds, and select at random a kind of HARQ feedback information to carry out data re-transmission, or, with reference to default priority, choosing a kind of HARQ feedback information that current priority is the highest carries out after data re-transmission, at the upper identical HARQ feedback bits that once still receives UE transmission, and while still there is ambiguity in corresponding HARQ feedback information, can carry out data re-transmission according to unselected other HARQ feedback informations of last time, if carry out after data re-transmission according to unselected other HARQ feedback informations of last time, at the upper identical HARQ feedback bits that once still receives UE transmission, and still there is ambiguity in corresponding HARQ feedback information, further, there is not non-selected HARQ feedback information, so, eNB should be based on above-mentioned HARQ feedback bits, and the credit rating corresponding HARQ feedback information when " poor " of eating dishes without rice or wine carries out data re-transmission, above-mentioned, there is ambiguous HARQ feedback information indication, the descending sub frame that likely occurs error of transmission carries out data re-transmission.
For example, consult shown in table 7, for convenience of description, in the embodiment of the present invention, based on table 6, to thering is the credit rating of eating dishes without rice or wine that ambiguous HARQ feedback information is corresponding, make further numbering, as shown in table 7, by correspondence eat dishes without rice or wine credit rating be numbered HARQ feedback information 1. further difference be, correspondence credit rating numbering 1. _ 1 and the correspondence credit rating numbering 1. _ 2 of eating dishes without rice or wine of eating dishes without rice or wine.
Table 7
So, as shown in table 7, if eNB receives the HARQ feedback bits b (0) that UE sends, b (1) is " 1; 0 " and the current credit rating of eating dishes without rice or wine is for " good ", and 1. the credit rating of eating dishes without rice or wine is numbered, the HARQ feedback information " ACK; ACK; ACK, NACK/DTX " of preferential credit rating numbering 1. _ 1 correspondence of selecting to eat dishes without rice or wine of eNB carries out data re-transmission, for the 4th descending sub frame, carries out data re-transmission; If the HARQ feedback bits b (0) that the UE next time receiving sends, b (1) is still " 1; 0 " and the current credit rating of eating dishes without rice or wine is for " good ", the HARQ feedback information " ACK, ACK, NACK/DTX; ACK " of preferential credit rating numbering 1. _ 2 correspondences of selecting to eat dishes without rice or wine of eNB carries out data re-transmission, for the 3rd descending sub frame, carries out data re-transmission; If the HARQ feedback bits b (0) that the UE next time receiving again sends, b (1) is still " 1; 0 " and the current credit rating of eating dishes without rice or wine is for " good ", and the HARQ feedback information of now eat dishes without rice or wine credit rating numbering 1. _ 1 and credit rating numbering 1. _ 2 correspondences of eating dishes without rice or wine had all been selected, so, the descending sub frame that may make a mistake all should be carried out to data re-transmission, be that the HARQ feedback information that eNB numbers 2 correspondences according to the credit rating of eating dishes without rice or wine carries out data re-transmission, for the 3rd descending sub frame and the 4th descending sub frame, carry out data re-transmission.
The b (0) sending for UE, b (1) is the situation of " 0,1 ", is equally applicable to above-mentioned each flow process, does not repeat them here.
In the embodiment of the present invention, network side is distinguished different HARQ feedback informations corresponding to same HARQ feedback bits according to the credit rating of eating dishes without rice or wine, like this, network side receives after the HARQ feedback bits of end side transmission, just can select matched HARQ feedback information to carry out data re-transmission based on the current credit rating of eating dishes without rice or wine, thereby effectively reduce the misjudged probability of descending sub frame reception condition, avoided the meaningless re-transmission of descending sub frame, saved to a certain extent interface-free resources.And the realization of the embodiment of the present invention has very high compatibility, do not need original system to make large change, saved and realized cost.
