Include following steps：
Step 110, determine according to subframe configuration information whether the first default subframe and the second default subframe are obscured.
Wherein, the first default subframe and the second default subframe, which are used to carry, confirms feedback information.Subframe configuration information includes
Sub-frame configuration parameter, feedback window length.
Specifically, when the confirmation feedback system of hybrid automatic repeat-request use multiplexing, and sub-frame configuration parameter is default
Sub-frame configuration parameter, feedback window length are default feedback window length, then according to the two of feedback information bit values, the mixing certainly
The PUCCH format and the numbering of PUCCH resource index that dynamic repeat requests HARQ-A/NCK feedbacks use determine the first default son
Whether frame and the second default subframe are obscured.
Default sub-frame configuration parameter is the sub-frame configuration parameter 2 in the Table 10.1.3.1-1 of 36.213 agreements, is preset
Feedback window length is 4.
Described first default subframe is default special subframe, and the described second default subframe is the first default conventional subframe；Phase
Answer, two bit values, the hybrid automatic repeat-request HARQ-A/NCK according to feedback information feeds back what is used
PUCCH format and the numbering of PUCCH resource index determine whether the first default subframe and the second default subframe are obscured, and wrap
Include：
If according to the 10.1.3-4 forms of 36.213 agreements, according to b (0), b (1)=1,0 andConfigured,
Then the default special subframe and the first default conventional subframe occur special subframe and obscured with conventional subframe, wherein, b (0),
B (1) represents two bit values of feedback information,Represent that the hybrid automatic repeat-request HARQ-A/NCK feedbacks use
PUCCH format be PUCCH format 1b, the PUCCH moneys that the hybrid automatic repeat-request HARQ-A/NCK feedbacks use

The numbering for the PUCCH resource index that the hybrid automatic repeat-request HARQ-A/NCK feedbacks use is 3.
In existing 3GPP standards, when using HARQ-ACK multiplexing feedback systems on PUCCH channels,
Now, base station (eNodeB) side can not correctly make a distinction, and easily cause flase drop, false retrieval, and the reason for flase drop, false retrieval occurs is
Special subframe be present and (alternatively referred to as descending special subframe is obscured with descending conventional subframe) and conventional subframe are obscured with conventional subframe
Obscure (alternatively referred to as descending conventional subframe is obscured with descending conventional subframe) with conventional subframe.Produce the reason for above two is obscured
It is：
Referring to table 1, when subframe is configured to 2/7 (DSUDD DSUDD/10:2:2) when, i.e., subframe configuration parameter is 2 in table 1,
For sub-frame of uplink (subframe, SF) 2,7, the HARQ-ACK feedbacks of corresponding 4 descending sub frames of each sub-frame of uplink, feedback window
M=4, there are 4 K values.Wherein, table 1 be agreement in TDD descending sub frame allocation list, the Table (form) of 36.213 agreements
10.1.3.1-1(Downlink association set indexK:{k0,k1,…kM-1For TDD), "-" represents in table 1
Without configuration.The 0~6 of subframe configuration parameter file represents the sub-frame configuration type of seven kinds of 3GPP protocol definitions in table 1.Sub-frame configuration
2/7 (DSUDD DSUDD/10 of position:2:2) it is special, to represent second subframe in up frame data and the 7th subframe being configured to
Subframe, altogether two special subframes, this configuration mode correspond to sub-frame configuration parameter 2, i.e., subframe configuration parameter position 2 in table 1
A line.In the row, sub-frame of uplink 2 and sub-frame of uplink 7 are respectively two special subframes, and sub-frame of uplink 2 and sub-frame of uplink 7 are right
The HARQ-ACK feedbacks for the descending sub frame answered point are 8,7,4,6,8,7,4,6 to correspond to different index k respectively.Due to by 8,
7th, 4,6 subframes are fed back, it may thus be appreciated that the length of feedback window is 4.
Table 1 (Table 10.1.3.1-1)
Table 2 (Table 10.1.3-4)
Table 2 give feedback window for 4 when, when configure feedback information be 2bit when, feedback information item.Wherein, b (0),
B (1) represents that the bit numbers of HARQ-A/NCK feedbacks are 2bit, and respectively with b (0), b (1) is represented, b (0), b (1) are can obtain after set
=0,1；Or b (0), b (1)=1,0；Or b (0), b (1)=0,0；Or b (0), b (1)=1,1.As shown in Table 1, subframe
When configuring 2, descending HARQ-A/NCK is fed back on sub-frame of uplink 2,7, and corresponding K values are respectively：k0=8, k1=7, k2=
4、k3=6.According to the definition of 3GPP agreements, descending PDSCH and descending HARQ-A/NCK sequential relationship are n-k, i.e. under n-K is
Subframe numbers corresponding to row subframe PDSCH.
During n=2 (sub-frame of uplink numbering)：
The subframe 4 of the upper radio frames of 2-8=4//correspondence；Wherein "-" represents corresponding relation；
The subframe 5 of the upper radio frames of 2-7=5//correspondence；
The subframe 8 of the upper radio frames of 2-4=8//correspondence；
The subframe 6 of the upper radio frames of 2-6=6//correspondence.
During n=7 (sub-frame of uplink numbering)：
The subframe 9 of the upper radio frames of 7-8=9//correspondence；
The subframe 0 of 7-7=0//correspondence and the same radio frames of the sub-frame of uplink；
The subframe 3 of 7-4=3//correspondence and the same radio frames of the sub-frame of uplink；
The subframe 1 of 7-6=1//correspondence and the same radio frames of the sub-frame of uplink.
Due to { the k in HARQ-ACK (i) " i " and Table 10.1.3.1-1 tables0,k1,…kM-1M-1 is one a pair
Should, therefore understood based on table 2, HARQ-ACK (0), HARQ-ACK (1), HARQ-ACK (2), HARQ-ACK (3) and SF4/5/8/
6；SF9/0/3/1 is corresponded.In order to more clearly represent corresponding relation, above-mentioned corresponding relation is indicated by table 3.
By taking SF4 (2-8) as an example, it represents that HARQ-ACK (0) of descending sub frame corresponding to feedback subframe SF2 is SF4, why for SF4
Because being obtained according to corresponding relation 2-8=4.
Table 3
From table 2 search b (0), b (1)=1,0 andWhen HARQ-ACK feedbacks, wherein SF2 feedback information is such as
Shown in table 4, SF7 feedback information is as shown in table 5.Wherein,The lower right corner footmark " 0,1,2,3 " represent HARQ-A/
The numbering for the PUCCH resource index that NCK feedbacks use, i.e. km-1M-1.The footmark " (1) " in the upper left corner represents that HARQ-A/NCK is anti-
It is PUCCH format 1b to present the PUCCH format used.
Table 4
Table 5
According to table 4 provide SF2 on HARQ-ACK feed back, when b (0), b (1)=1,0 andWhen, SF8 (HARQ-
ACK (2)) and SF6 (HARQ-ACK (3)) corresponding to HARQ-ACK, base station (eNodeB) side will be unable to distinguish.Reason is,
HARQ-ACK (2) HARQ feedback result has three kinds：ACK, NACK/DTX, NACK/DTX, can not be accurate for base station side
Judge current HARQ feedback actually be ACK or NACK/DTX.Similarly, according on the SF7 of the offer of table 5
HARQ-ACK feedback work as, b (0), b (1)=1,0 andWhen, SF3 (HARQ-ACK (2)) and SF1 (HARQ-ACK (3)) are right
The HARQ-ACK answered, eNodeB side will be unable to distinguish.
It can be seen that the subframe obscured is the default conventional subframe SF3 of default special subframe SF1 and first, in the present embodiment
Such case is referred to as special subframe (also known as " the HARQ-ACK of DWPTS and descending conventional subframe feedbacks are obscured with conventional subframe
Obscure ").
Similarly, from table 2 search b (0), b (1)=0,1 andWhen HARQ-ACK feedbacks, wherein SF2 feedback
Information is as shown in table 6, and SF7 feedback information is as shown in table 7.
Table 6
Table 7
According to table 6 provide SF2 on HARQ-ACK feed back, when b (0), b (1)=0,1 andWhen, SF4 (HARQ-
ACK (2)) and SF5 (HARQ-ACK (3)) corresponding to HARQ-ACK, eNodeB sides will be unable to distinguish.On the SF7 provided according to table 7
HARQ-ACK feedback work as, b (0), b (1)=0,1 andWhen, SF9 (HARQ-ACK (2)) and SF0 (HARQ-ACK (3))
Corresponding HARQ-ACK, eNodeB side will be unable to distinguish.
It can be seen that the subframe obscured is the second conventional subframe SF9 and the 3rd conventional subframe SF0, by this in the present embodiment
Kind situation is referred to as conventional subframe and the (also known as " HARQ-ACK of descending conventional subframe and descending conventional subframe is obscured with conventional subframe
Feedback is obscured ").Optionally, the second conventional subframe SF0 and the 3rd conventional subframe SF9.
Exemplary, as shown in Fig. 2 step 110 can be embodied as：
Step 201, the feedback system of the high-rise hybrid automatic repeat-request for configuring TDD are multiplexing (multiplexing) side
Formula.Perform step 202.
Step 202, judge whether HARQ feedback window length M is 4, and whether sub-frame configuration parameter is 2.If it is, hold
Row step 203.If it is not, then perform step 204.
Step 203, according to two bit values of feedback information, hybrid automatic repeat-request HARQ-A/NCK feed back what is used
PUCCH format and the numbering of PUCCH resource index determine whether the first default subframe and the second default subframe are obscured.
If specifically, according to the 10.1.3-4 forms of 36.213 agreements, according to b (0), b (1)=1,0 andEnter
Row configuration, then the default special subframe and the first default conventional subframe occur special subframe and obscured with conventional subframe.Such as
Fruit is according to the 10.1.3-4 forms of 36.213 agreements, according to b (0), b (1)=0,1 andConfigured, then described second
Default conventional subframe and the 3rd default conventional subframe occur conventional subframe and obscured with conventional subframe.
Step 204, by normal multiplexing (multiplexing) process of feedback processing.
Step 120, if it happens obscure, then according to the data of the first default subframe or the second default subframe send situation with
And retransmit the type that situation determines the feedback information of the first default subframe and the second default subframe carrying.
Specifically, when special subframe occurring and conventional subframe is obscured, as described in Figure 3, step 120 can be embodied as：
Step 301, if it happens special subframe and conventional subframe are obscured, then judge whether default special subframe sends number
According to.If not sending data, step 302 is performed；Otherwise, if sending data, step 303 is performed.
If step 302, default special subframe do not send data, the feedback information class of the first default conventional subframe carrying
Type presses ACK processing.
Specifically, i.e. DWPTS be configured to special subframe with set to 0,5 when, SF6/SF1 is without Physical Downlink Shared Channel
(Physical Downlink Shared Channel, PDSCH) data transfer, then its HARQ-ACK feedback be not present.
A) DWPTS SF6 and SF8 HARQ-ACK feedbacks useResource indexAnd b (0), b (1)=1,
0。
B) DWPTS SF1 and SF3 HARQ-ACK feedbacks useResource indexAnd b (0), b (1)=1,
0。
A), b) conventional subframe SF8, SF3 under two kinds of scenes press ACK processing, i.e., final HARQ-ACK (0) --- HARQ-
ACK (2) is fed back to ACK/ACK/ACK.
If step 303, default special subframe send data, default special subframe and the first default conventional subframe are judged
Whether it is to retransmit or just pass, feedback information types is determined according to transmission situation.
If specifically, the default special subframe sends data, and the default special subframe and described first is preset
Conventional subframe is just to pass, then：
(1) the first MCS and the 2nd MCS is calculated, wherein, the first MCS is MCS corresponding to the default special subframe,
2nd MCS is MCS corresponding to the described first default conventional subframe.
(2) MCS differences are calculated according to the first MCS and the 2nd MCS.
(3) if the MCS differences are more than predetermined threshold value, the described first default conventional subframe presses NACK processing.
(4) if the MCS differences are less than or equal to the predetermined threshold value, the default special subframe is by NACK
Reason.
MCS refers to coded modulation scheme (Modulation and Coding Scheme, MCS), can be according to downlink certainly
Code modulation mode algorithm is adapted to be calculated.Here only make a brief description：UE is according to the quality of the downlink of measurement to base
Side of standing reports descending CQI value, and base station side is according to the descending CQI value detected, then in conjunction with descending error code no more than 10%
Principle, a suitable descending MCS is selected, as the code modulation mode of the downlink data transmission of the descending sub frame.
If step 304, default special subframe and the first default conventional subframe send data, and default special subframe is
Just pass, the first default conventional subframe then presets special subframe and press NACK processing to retransmit.
Preferably, preset special subframe and send data.
If step 305, default special subframe send data, and default special subframe and the first default conventional subframe are
Retransmit, then the number of retransmissions of relatively more default special subframe and the first default conventional subframe, the less subframe of number of retransmissions presses NACK
Processing；If the number of retransmissions of default special subframe and the first default conventional subframe is identical, presets special subframe and first and preset
Conventional subframe presses NACK processing.
By the method shown in Fig. 3, can ensure to retransmit based on preferential when special subframe occurring and conventional subframe is obscured
The factor such as transmission reliability, determine that feedback information types are carried out, improve discrimination.
Specifically, when conventional subframe occurring and conventional subframe is obscured, as described in Figure 4, step 120 can be embodied as：
Step 401, obscure in the event of conventional subframe and conventional subframe, then obtain second and preset conventional subframe and the 3rd pre-
If the data of conventional subframe send situation.
If step 402, the second default conventional subframe do not send data, the 3rd default conventional subframe presses ACK processing.
If step 403, the second default conventional subframe and the 3rd default conventional subframe send data, and second is default normal
Rule subframe and the 3rd default conventional subframe are just to pass, then the second default conventional subframe and the 3rd default conventional subframe press NACK
Processing.
If step 404, the second default conventional subframe and the 3rd default conventional subframe send data, and second is default normal
Subframe is advised just to pass, the 3rd default conventional subframe is retransmits, then the second default conventional subframe presses NACK processing.
If step 405, the second default conventional subframe send data, and the second default conventional subframe and the 3rd default routine
Subframe is to retransmit, then compares the number of retransmissions of the second default conventional subframe and the 3rd default conventional subframe, and number of retransmissions is less
Subframe press NACK processing；If the number of retransmissions of the second default conventional subframe and the 3rd default conventional subframe is identical, second is pre-
If conventional subframe and the 3rd default conventional subframe press NACK processing.
By the method shown in Fig. 4, can ensure to retransmit based on preferential when conventional subframe occurring and conventional subframe is obscured
The factor such as transmission reliability, determine that feedback information types are carried out, improve discrimination.
Understood according to step 303 and step 304 and step 404 and step 405, according to the described first default subframe or institute
State the data transmission situation of the second default subframe and retransmit situation and determine the described first default subframe and the second default son
The type of the feedback information of frame carrying, including：
If the described first default subframe and the second default subframe send data, and the described first default subframe is
Just pass, the described second default subframe is retransmits, then the described first default subframe presses NACK processing；
If the described first default subframe sends data, and the described first default subframe and the second default subframe are
Retransmit, then the number of retransmissions of the more described first default subframe and the second default subframe, the less subframe of number of retransmissions is pressed
NACK processing；If the described first default subframe is identical with the number of retransmissions of the described second default subframe, the described first default son
Frame and the second default subframe press NACK processing.
Below by a specific usage scenario, above-described embodiment is further described：
The AckNackFeedbackMode of 1.RRC configurations is multiplexing patterns, sub-frame configuration 2.Work as HARQ-ACK
When feedback window M values are more than 1 less than 4, normal multiplexing HARQ-ACK process of feedbacks are walked.As HARQ-ACK feedback windows M
When value is equal to 4, the feedback optimized flows of multiplexing HARQ-ACK are walked.The feedback optimized streams of multiplexing HARQ-ACK
Journey is shown in step 2-3.
