Description
Technical field
The present invention relates to the communications field, particularly a kind of method and device of handling the HARQ feedback bits.
Background technology
At LTE (Long Term Evolution, Long Term Evolution) in the system, can accurately grasp the data receiving state of end side in order to make network side, UE (User Equipment, user terminal) need 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, be also referred to as HARQ (Hybrid Automatic Repeat Reuqest mixes automatic repeat requests) feedback information.
In 3GPP 36.213R880 agreement, stipulate, when current UE adopts ACK/NACK Multiplexing (multiplexing) mode transfer HARQ feedback information, adopt PUCCH (Physical Uplink ControlChannel, Physical Uplink Control Channel) to carry this HARQ feedback information; Be subject to the transmission means of PUCCH, usually only support the HARQ feedback of 2 bits on PUCCH, 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) transmits by PUCCH again.
Usually in the system parameter M is set, is used to characterize the descending sub frame quantity that UE need carry out the HARQ feedback at same sub-frame of uplink, for different uplink-downlink configuration and sub-frame of uplink, the value difference of M.For example, consult shown in table 1, table 2 and the table 3, represent that respectively the M value is 2,3 and at 4 o'clock, the HARQ feedback information of configuration and the mapping relations between the HARQ feedback bits, and the numbering that sends the PUCCH that the HARQ feedback bits adopted.
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) exists
On the b (0) that receives, b (1) is " 1,0 ", perhaps exists
On receive b (0), when b (1) is " 0,1 ", after, ambiguity has all appearred in its corresponding HARQ feedback information, i.e. the mapping relations of one-to-many have appearred in b (0) between b (1) and the HARQ feedback information.For example, consult shown in the 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 the prior art, when there was ambiguity in the HARQ feedback information of the HARQ feedback bits correspondence that receives as eNB, eNB can't determine the descending sub frame reception condition of UE, can't judge that promptly UE has correctly received several descending sub frames.In order to guarantee systematic function, common way is in direct a plurality of HARQ feedback informations with a HARQ feedback bits correspondence at present, characterizes the feedback result of a poorest HARQ feedback information of UE reception as final reception.For example, consult shown in the table 5, as the b (0) that receives, when b (1) is " 1,0 ", confirm that the HARQ feedback information that receives is " ACK; ACK, NACK/DTX, NACK/DTX ", exist two to receive wrong descending sub frames in the descending sub frame that sign UE receives, and work as the b (0) that receives, b (1) is " 0; 1 " the time, 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 at 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 at receiving two wrong descending sub frames, just increased the misjudged probability of descending sub frame to a great extent, and the number of retransmissions that has increased descending sub frame, serious waste interface-free resources.

Consult shown in the table 6, in the embodiment of the invention, at first will preset HARQ feedback bits b (0), b (1), HARQ feedback information, and the mapping relations between the credit rating of eating dishes without rice or wine, specific as follows:
Table 6
As shown in table 6, mapping to b (0), b (1) " 1; 0 " the 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 of NACK/DTX correspondence; " ACK, ACK, NACK/DTX, NACK/DTX " being numbered 2. of the corresponding credit rating of eating dishes without rice or wine; Simultaneously, mapping to b (0), b (1) " 0; 1 " the 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 " NACK/DTX, NACK/DTX; ACK, ACK " the corresponding credit rating of eating dishes without rice or wine; In the present embodiment, the credit rating of eating dishes without rice or wine be numbered 1. the 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. the 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 Figure 2ly, in the embodiment of the invention, eNB is as follows based on the detailed process of the HARQ feedback bits that the quality treatment UE that eats dishes without rice or wine of UE sends:
Step 200:eNB receives the HARQ feedback bits that UE sends on the 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 invention, when execution in step 210, 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 the LTE of reality, the CSI (channel condition information) that eNB adopts the Block Error Rate of UE that UE is reported usually revises, and be the UE distributing radio resource in next dispatching cycle according to amended CSI, wherein, CSI comprises CQI (channel quality information), PMI (pre-coding matrix indication) and RI (order indication); And the spectrum efficiency of network side (being also referred to as output spectrum efficient) normally obtains based on the revised CQI of UE.This shows that eNB judges that based on the Block Error Rate of UE and the spectrum efficiency of network side the current credit rating of eating dishes without rice or wine is very reliable.In the present embodiment, be provided with following parameter based on above-mentioned Block Error Rate and spectrum efficiency:
BLER_High_Threshold is used to judge the Block Error Rate high threshold of the current credit rating of eating dishes without rice or wine, and when the Block Error Rate of UE is higher than this thresholding, confirms that the current credit rating of eating dishes without rice or wine is " poor ";
BLER_Low_Threshold: be used to judge 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 lower than this thresholding, confirm that the current credit rating of eating dishes without rice or wine is " good ".
Eff_High_Threshold: be used to judge the spectrum efficiency high threshold of the current credit rating of eating dishes without rice or wine, when the spectrum efficiency of UE is higher than this threshold value, confirm that the current credit rating of eating dishes without rice or wine is " good ";
Eff_Low_Threshold: be used to judge the spectrum efficiency low threshold of the current credit rating of eating dishes without rice or wine, when the spectrum efficiency of UE is lower than this threshold value, confirm that the current credit rating of eating dishes without rice or wine is " 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 was set, in order to reduce the erroneous judgement of eNB, the thresholding of Block Error Rate and the thresholding of spectrum efficiency should strict 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, preferable, the high threshold of spectrum efficiency is set to 5.1152 (CQI Index=14), and the low threshold of spectrum efficiency is set to 0.8770 (CQI Index=5) relatively rationally.
Based on above-mentioned parameter, in the present embodiment, the spectrum efficiency that receives the Block Error Rate of data and network side according to UE determines that current eating dishes without rice or wine comprises during credit rating:
If, MCS_BLER (i)＜BLER_Low_Threshold,
And Mcs_eff
Out(i)＞and Eff_High_Threshold, confirm that then the current credit rating of eating dishes without rice or wine is " good ", 1. the credit rating of eating dishes without rice or wine shown in the correspondence table 6 numbers;
If MCS_BLER (i)＞BLER_High_Threshold,
And Mcs_eff
Out(i)＜and Eff_Low_Threshold, confirm that then the current credit rating of eating dishes without rice or wine is " poor ", 2. the credit rating of eating dishes without rice or wine shown in the correspondence table 6 numbers;
If do not meet above-mentioned two kinds of situations, confirm that then 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 " correspondence table 6 numbers.
In the 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 numbering expressions of eating dishes without rice or wine, in the present embodiment, adopt same reference numeral only for giving an example.
Step 220:eNB determines and the HARQ feedback bits and the corresponding HARQ feedback information of the current credit rating of eating dishes without rice or wine that receive according to the mapping relations between default HARQ feedback bits, the credit rating of eating dishes without rice or wine and the HARQ feedback bits.
Step 230:eNB carries out corresponding data re-transmission according to the HARQ feedback information that obtains.
For example, if the b (0) that eNB receives, b (1) be " 1,0 ", and when confirming the current credit rating of eating dishes without rice or wine for " good ", adopt eat dishes without rice or wine the 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 when confirming the current credit rating of eating dishes without rice or wine for " generally ", the HARQ feedback information of correspondence carries out data re-transmission to adopt the credit rating of eating dishes without rice or wine to number 2.;
If the b (0) that eNB receives, b (1) be " 1,0 ", and when confirming the current credit rating of eating dishes without rice or wine for " poor ", the HARQ feedback information of correspondence carries out data re-transmission to adopt the credit rating of eating dishes without rice or wine to number 2.;
Wherein, if determining the HARQ feedback information corresponding with HARQ feedback bits that receives and the current credit rating of eating dishes without rice or wine, eNB has at least two kinds, as, consult shown in the table 6, suppose the b (0) that eNB receives, b (1) is " 1,0 ", and confirms that the current credit rating of eating dishes without rice or wine is " good ", the 1. corresponding HARQ feedback information of the credit rating numbering of then eating dishes without rice or wine this moment has " ACK; ACK, ACK, NACK/DTX " and " ACK; ACK; NACK/DTX, ACK " two kinds (also can be provided with 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 choosing of ambiguous HARQ feedback information is equivalent (being that probability of happening is suitable) that then eNB can adopt the exploration selection mode, as, eNB can select a kind of HARQ feedback information to carry out data re-transmission at random, also can select the highest a kind of HARQ feedback information of current priority to carry out data re-transmission according to the priority that sets in advance.
Based on the foregoing description, in the practical application, if determining the HARQ feedback information corresponding with HARQ feedback bits that receives and the current credit rating of eating dishes without rice or wine, eNB has at least two kinds, and select a kind of HARQ feedback information to carry out data re-transmission at random, perhaps, after choosing the highest a kind of HARQ feedback information of current priority and carry out data re-transmission with reference to default priority, still receive the identical HARQ feedback bits that UE sends next time, and when still there is ambiguity in corresponding HARQ feedback information, then can carry out data re-transmission according to unselected other HARQ feedback informations of last time; After if unselected other HARQ feedback informations carry out data re-transmission according to the last time, still receive the identical HARQ feedback bits that UE sends next time, and still there is ambiguity in corresponding HARQ feedback information, further, there has not been non-selected HARQ feedback information, so, eNB should be based on above-mentioned HARQ feedback bits, and the credit rating pairing HARQ feedback information when " poor " of eating dishes without rice or wine carries out data re-transmission, promptly have an ambiguous HARQ feedback information indication above-mentioned, error of transmission might appear and descending sub frame carry out data re-transmission.
For example, consult shown in the table 7, for convenience of description, in the embodiment of the invention, based on table 6, the credit rating of eating dishes without rice or wine with ambiguous HARQ feedback information correspondence is made further numbering, as shown in table 7, with correspondence eat dishes without rice or wine credit rating be numbered 1. the HARQ feedback information further difference be, correspondence eat dishes without rice or wine the credit rating numbering 1. _ 1 and correspondence eat dishes without rice or wine the credit rating numbering 1. _ 2.
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 promptly eating dishes without rice or wine is numbered, then eNB preferential select to eat dishes without rice or wine the credit rating numbering 1. _ 1 the HARQ feedback information of correspondence " ACK; ACK; ACK, NACK/DTX " carry out data re-transmission, promptly carry out data re-transmission at the 4th descending sub frame; If the HARQ feedback bits b (0) of the UE that next time receives transmission, b (1) still is " 1; 0 " and the current credit rating of eating dishes without rice or wine is " good ", then eNB preferential select to eat dishes without rice or wine the credit rating numbering 1. _ 2 the HARQ feedback information of correspondence " ACK, ACK, NACK/DTX; ACK " carry out data re-transmission, promptly carry out data re-transmission at the 3rd descending sub frame; If the HARQ feedback bits b (0) of the UE that next time receives again transmission, b (1) still is " 1; 0 " and the current credit rating of eating dishes without rice or wine is " good ", and eat dishes without rice or wine this moment credit rating numbering 1. _ 1 and eat dishes without rice or wine the credit rating numbering 1. _ 2 the HARQ feedback information of correspondence all selected, so, the descending sub frame that may make a mistake all should be carried out 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, promptly carry out data re-transmission at the 3rd descending sub frame and the 4th descending sub frame.
For the b (0) that UE sends, 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 invention, network side is distinguished the different HARQ feedback informations of same HARQ feedback bits correspondence according to the credit rating of eating dishes without rice or wine, like this, after network side receives 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 interface-free resources to a certain extent.And the realization of the embodiment of the invention has very high compatibility, does not need original system is made big change, has saved the realization cost.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
