Embodiment
Of background technology, for the downstream arrangements 1-6 in the LTE-A TDD system, when the base station polymerization a plurality of descending carriers when UE sends data, UE will feed back a plurality of descending sub frames and the pairing ACK/NACK information of a plurality of descending carrier in a sub-frame of uplink.For reducing the ACK/NACK feedback overhead, need part A CK/NACK information be merged.
If carry out frequency domain combination, because the PDSCH correlation on the different carrier is relatively poor, therefore, the efficiency of transmission of the serious reduction of meeting system.
If merge and carry out time domain; Because UE can't know the scheduling situation of base station in a plurality of descending sub frames, therefore, can't judge whether accurately that PDSCH loses; When the PDSCH in the subframe that particularly is scheduled at last in the feedback window all loses; At this moment, the ACK/NACK information of UE feedback can not reflect the reception condition of data really, thus the reliability of influence transmission.
For the problems referred to above, prior art does not have suitable solution.
Based on above reason, the embodiment of the invention has provided a kind of transmission method of the ACK/NACK feedback information that merges based on time domain.
As shown in Figure 3, the schematic flow sheet of the transmission method of a kind of ACK/NACK feedback information that proposes for the embodiment of the invention, this method specifically may further comprise the steps:
Step S301, terminal equipment receive the data that send the base station through a plurality of descending sub frames in a plurality of descending carriers, and generate corresponding ACK/NACK feedback information according to the data that receive.
Wherein, the ACK/NACK feedback information of the data in corresponding a plurality of descending sub frame need transmit in same sub-frame of uplink.
Step S302, terminal equipment carry out time domain to the ACK/NACK feedback information in the different descending sub frames in the same descending carrier and merge, and generate corresponding ACK/NACK feedback bits.
In the application scenarios of reality, the implementation procedure of this step comprises the processing of following two aspects:
(1) terminal equipment detects whether there is data-bag lost respectively in each descending carrier.
In practical application; Concrete judgment mode is that terminal equipment is respectively according to the DAI information in the descending scheduling indication (DL grant) received on the different descending sub frames in each descending carrier; Confirm whether there is data-bag lost in the descending carrier, wherein the DAI information among the DL grant can be indicated the data packet number of base station actual schedule in each subframe.
Wherein, the constituted mode of DAI information specifically comprises:
DAI information comprises DAI
fAnd DAI
t, promptly the DAI among the DL grant do as a whole, wherein, DAI
fThe packet sum that is used to indicate a sub-frame on different descending carriers, to be dispatched, DAI
tBe used in reference to and be shown in each carrier wave, the sum of the packet of being dispatched till the current subframe, its example in concrete application scenarios shown in Fig. 4 A, wherein, DAI
tIdentical with 2 bit DAI among the Rel-8TDD DL grant; Or,
DAI information is specially DAI
Total1, promptly the DAI among the DL grant do as a whole, wherein, DAI
Total1Be used in reference in a plurality of descending sub frames that are shown in a plurality of descending carriers, the sum of data dispatching bag till the current subframe, its example in concrete application scenarios shown in Fig. 4 B, wherein, DAI
Total1Can comprise 2 bit DAI among the Rel-8TDD DL grant, and DAI
Total1Be at least 3 bits; Or,
DAI information is specially DAI
Total2, wherein, DAI
Total2The packet sum that is used to indicate current subframe on different descending carriers, to be dispatched, its example in concrete application scenarios shown in Fig. 4 C, wherein, DAI
Total2Can comprise 2 bit DAI among the Rel-8TDD DL grant, and DAI
Total2Be at least 2 bits.
It is pointed out that in the formation scheme of above-mentioned DAI information mentioned packet specifically comprises dynamic dispatching PDSCH or SPS resource release signaling.
(2) terminal equipment generates the ACK/NACK feedback bits of corresponding downstream carrier wave respectively according to the ACK/NACK feedback information content in the different descending sub frames in the testing result in each descending carrier and the corresponding downstream carrier wave, and concrete create-rule is following:
If terminal equipment detects data-bag lost in a descending carrier, then terminal equipment is DTX to the ACK/NACK feedback bits that the ACK/NACK feedback information in the descending carrier carries out generating after time domain merges;
If terminal equipment is confirmed to comprise at least one NACK in the ACK/NACK feedback information in the different descending sub frames in the descending carrier; And terminal equipment does not detect data-bag lost in descending carrier, and then terminal equipment is NACK to the ACK/NACK feedback bits that the ACK/NACK feedback information in the descending carrier carries out generating after time domain merges;
If terminal equipment confirms that the ACK/NACK feedback information in the different descending sub frames in the descending carrier all is ACK; And terminal equipment does not detect data-bag lost in descending carrier, and then terminal equipment is ACK to the ACK/NACK feedback bits that the ACK/NACK feedback information in the descending carrier carries out generating after time domain merges.
Need further be pointed out that; If what adopt in the current system is the pattern of single codeword transmission; So, each descending carrier can directly generate a corresponding ACK/NACK feedback bits, still; Application scenarios for many codeword transmission pattern; For example: data of transmitting with the MIMO mode that receive through a plurality of descending sub frames in C the descending carrier that the base station sends when terminal equipment, and need be when the ACK/NACK feedback bits of a base station feedback L bit, the processing procedure of this step will be according to several kinds of situation below the existence of the magnitude relationship between C and the L:
If terminal equipment is confirmed C=L; Terminal equipment carries out time domain to the ACK/NACK feedback information in the different descending sub frames in the same descending carrier and merges; Generate an ACK/NACK feedback bits; Be UE respectively the pairing ACK/NACK information of different code words on the descending carrier to each polymerization (perhaps transmission block, transport block) merge (being called for short the space merges).After the ACK/NACK space merges, carry out time domain and merge, shown in Fig. 5 A, C=2, M=4, UE generate 2 bit feedback information (b
0, b
1).
If terminal equipment is confirmed 2C=L, terminal equipment carries out time domain to the ACK/NACK feedback information of the same code word under in the different descending sub frames in the same descending carrier and merges, and generates two ACK/NACK feedback bits; Promptly directly the same code word in the different descending sub frames is merged and do not carry out the space and merge; Shown in Fig. 5 B, C=2, M=4; And L=4, UE generate 4 bit feedback information (b
0, b
1, b
2, b
3).
If terminal equipment is confirmed C＜L＜2C; Terminal equipment carries out time domain to the ACK/NACK feedback information in the different descending sub frames in each carrier wave in the 2C-L in C the descending carrier the descending auxilliary carrier wave and merges; Generate an ACK/NACK feedback bits; And the ACK/NACK feedback information of the same code word under in the different descending sub frames in each carrier wave in the downlink main carrier to carry in C the descending carrier and the remaining descending auxilliary carrier wave is carried out time domain merge; Generate two ACK/NACK feedback bits, promptly when carrying out the space merging, can preferentially merge descending subcarrier.
For example, C=2, M=2, and during L=3, UE carries out the space to 2C-L=1 descending carrier and merges, shown in Fig. 5 C.After the ACK/NACK space merges, carry out time domain and merge, UE generates 3 bit feedback information (b
0, b
1, b
2).。
The information of the descending sub frame that has transfer of data that step S303, terminal equipment basis receive generates supplementary.
UE is to base station feedback

1..., b
L-1Be the merging ACK/NACK information that obtains through above-mentioned processing,
Bit
Be used to indicate the information of the subframe that the PDSCH transmission is arranged that receives in the feedback window.The information of the subframe that the PDSCH transmission is arranged that receives in the feedback window.
In practical application,,, can be divided into following two kinds of situation according to corresponding generation foundation for supplementary:
(1) terminal equipment generates supplementary according to the sum of the descending sub frame that has transfer of data that receives.
This kind situation; More excellent the third scheme that is applicable to above-mentioned DAI information;
indication receives the sum (U) of the subframe of transfer of data; In the example as shown in Figure 6, U=3.During as
; The base station can confirm in this feedback window data-bag lost is arranged, and wherein
is the subframe sum of base station actual schedule.
(2) terminal equipment generates supplementary according to the numbering of last descending sub frame that has transfer of data that receives.
This kind situation; More excellent first kind and second kind of scheme being applicable to above-mentioned DAI information;
indication receives the numbering (V) in last subframe that transfer of data is arranged; Mapping relations between subframe numbering and
will define in advance; In the example as shown in Figure 6, V=2.During as
; The data-bag lost in the subframe of subframe numbering after V can be confirmed in the base station, and wherein
is last subframe numbering of base station actual schedule.
Wherein, no matter be above-mentioned (1) or (2), the bit number of supplementary receives the quantity of the descending sub frame of the data of sending the base station and confirms according to terminal equipment.
Need be pointed out that further that the above-mentioned descending sub frame that has transfer of data is specially the descending sub frame that has dynamic dispatching PDSCH or the transmission of SPS resource release signaling.
In practical application,,, can also be divided into following two kinds of situation according to corresponding generation foundation for supplementary:
(1) terminal equipment generates supplementary according to the sum of the descending sub frame of physical control channel (PDCCH) transmission that has needs ACK/NACK feedback that receives.
This kind situation; More excellent the third scheme that is applicable to above-mentioned DAI information;
indicates the sum (U) of the subframe of the descending sub frame transmission that receives the physical control channel (PDCCH) that needs the ACK/NACK feedback; In the example as shown in Figure 6, U=3.During as
; The base station can confirm in this feedback window data-bag lost is arranged, and wherein
is the descending sub frame transmission sum of the existence of the base station actual schedule physical control channel (PDCCH) that needs the ACK/NACK feedback.
(2) terminal equipment generates supplementary according to the numbering of last descending sub frame of physical control channel (PDCCH) transmission that has needs ACK/NACK feedback that receives.
This kind situation; More excellent first kind and second kind of scheme being applicable to above-mentioned DAI information;
indication receives last has the numbering (V) in the subframe that needs the transmission of the physical control channel (PDCCH) of ACK/NACK feedback; Mapping relations between subframe numbering and
will define in advance; In the example as shown in Figure 6, V=2.During as
; The loss of data in the subframe of subframe numbering after V can be confirmed in the base station, and wherein
is last subframe numbering of base station actual schedule.
Wherein, no matter be above-mentioned (1) or (2), the bit number of supplementary is confirmed according to the quantity that terminal equipment receives the descending sub frame of the physical control channel (PDCCH) that needs ACK/NACK feedback is arranged that sends the base station.
Need be pointed out that further that above-mentioned existence needs the descending sub frame of physical control channel (PDCCH) transmission of ACK/NACK feedback, be specially the descending sub frame that has dynamic dispatching PDSCH or the transmission of SPS resource release signaling.
In concrete application scenarios; When terminal equipment received the data of sending the base station through M descending sub frame, the bit number size of supplementary can be confirmed as
bit.
Step S304, terminal equipment send to the base station with ACK/NACK feedback bits and supplementary.
What need particularly point out is; When terminal equipment is merged into ACK/NACK feedback bits that each descending carrier generates and all is DTX through time domain; The processing of this step can directly be sent DTX for terminal equipment to the base station, representes all to exist in whole descending carriers the situation of data-bag lost.
Corresponding, in base station side, the embodiment of the invention provides corresponding handling process equally, and is specifically as shown in Figure 7, may further comprise the steps:
Step S701, base station are sent data through a plurality of descending sub frames in a plurality of descending carriers to terminal equipment.
ACK/NACK feedback bits and supplementary that step S702, base station receiving terminal apparatus return.
Wherein, The ACK/NACK feedback bits is that terminal equipment carries out generating after time domain merges to the ACK/NACK feedback information in the different descending sub frames in the same descending carrier, and supplementary is the information generation of terminal equipment according to the descending sub frame that has transfer of data that receives.
Need to prove; After the ACK/NACK feedback bits and supplementary that the base station receiving terminal apparatus returns; Comprise that also the base station carries out the deterministic process of the transmission state of each carrier wave according to the information that receives; Wherein, the base station can confirm in the data that terminal equipment sent, whether there is data-bag lost according to supplementary, and concrete deterministic process is following:
When supplementary is specially terminal equipment when generating according to the sum of the descending sub frame that has transfer of data that receives; The base station is the subframe sum and the indicated numerical value of supplementary of actual schedule relatively, confirms whether self exists data-bag lost in the data that terminal equipment sent;
When supplementary is specially terminal equipment when generating according to the numbering of last descending sub frame that has transfer of data that receives; The base station is the numbering and the indicated numbering of supplementary of last subframe of actual schedule relatively, confirms whether self exists data-bag lost in the data that terminal equipment sent.

It is pointed out that further that if in step S702 when ACK/NACK feedback bits that the base station receiving terminal apparatus returns and supplementary were specially DTX, the base station confirmed that all there is data-bag lost in each descending carrier that sends data to terminal equipment.
Compared with prior art, the embodiment of the invention has the following advantages:
Through using the technical scheme of the embodiment of the invention, in LTE-A TDD system, for the scene of multi-carrier polymerizing; Carry out time domain for the ACK/NACK feedback information in each descending carrier and merge, generate corresponding ACK/NACK feedback bits, and feed back to the base station with the supplementary that generates according to respective rule; Make the base station can know the data dispatch and the transmission situation of each descending carrier under the carrier aggregation scene; Thereby, under the situation that guarantee information is in time fed back, reduced transinformation; Reduce the feedback information expense, improved the reliability of transmission of feedback information.
Below, the application scenarios in conjunction with concrete describes the technical scheme that the embodiment of the invention proposed.
For the ease of explanation, unified is the following application scenarios of subsequent implementation example assumes:
If C=2, M=4, wherein carrier wave 0 is a main carrier, and carrier wave 1 is a subcarrier, and UE need be to base station feedback 4 bit informations.The base station has been dispatched subframe 0,1,3 respectively on carrier wave 0 in feedback window, on carrier wave 1, dispatched subframe 1,2,3 and carried out the PDSCH transmission, and UE has lost part PDSCH.
The first kind of scheme of the DAI information among the corresponding aforesaid step S302 and the assembled scheme of the situation (2) among the step S303; Wherein, if use second kind of scheme of the DAI information among the step S302, corresponding process is also similar with it; As shown in Figure 8, specify as follows.
The feedback procedure of UE end:
In subframe 1, the DAI on the carrier wave 1
f=1,2 PDSCH transmission that UE can have been known in this subframe base station scheduling, but on carrier wave 0, do not receive PDSCH, promptly PDSCH loses, then corresponding pooling information b on the carrier wave 0
0Be DTX.
Because all PDSCH have lost on the subframe 3, UE can't confirm in this subframe that the base station is not dispatch or PDSCH loses.Carrier wave 1 pairing pooling information b
1, will obtain based on subframe 1 and subframe 2 pairing ACK/NACK information merging.
Receive PDSCH in the subframe 0,1,2 of UE in this window; Last the descending scheduling subframe that receives is a subframe 2; If adopt the mapping relations shown in the table 2, then
Table 2 subframe numbering and supplementary mapping relations schematic table
The base station end receiving course:
The base station receives the feedback information b of UE
0, b
1,
Confirm that according to its value which PDSCH needs retransmits, wherein:
b
0Be DTX, then all PDSCH on the carrier wave 0 need to retransmit.
If b
1Be ACK, then the base station can confirm that the PDSCH of transmission on subframe in the carrier wave 11 and the subframe 2 is received by correct, need not retransmit it.If b
1Be NACK, then need retransmit.
The third scheme of DAI information among the corresponding aforesaid step S302 and the assembled scheme of the situation (1) among the step S303, as shown in Figure 9, specify as follows.
The feedback procedure of UE end:
Because this moment, DAI information only was used for indicating each subframe PDSCH scheduling situation, when the PDSCH in certain sub-frame all lost, whether UE can't judge had PDSCH to lose in this subframe, lose so UE can't confirm the PDSCH in subframe 0 and 3;
In subframe 1, the DAI on the carrier wave 1
f=1,2 PDSCH transmission that UE can have been known in this subframe base station scheduling, but on carrier wave 0, do not receive PDSCH, promptly PDSCH loses, then corresponding pooling information b on the carrier wave 0
0Be DTX.
Receive PDSCH in the subframe 0,1,2 of UE in this window; The scheduling subframe sum 2 that receives to the base station; If adopt the mapping relations shown in the table 3, then be
Table 3 receives sub-frame number and supplementary mapping relations schematic table
The base station end receiving course:
The base station receives the feedback information b of UE
0, b
1,
Confirm that according to its value which PDSCH needs retransmits, wherein:
It is to be noted; The above-mentioned mapping relations that provide only are a kind of examples that the embodiment of the invention provides for the ease of explanation; In concrete application scenarios, concrete mapping relations and assignment all can be adjusted according to actual needs, and such variation does not influence protection scope of the present invention.
On the other hand, in two above-mentioned embodiment, in subframe 3; UE does not receive corresponding PDSCH, because subframe 3 is last subframe in the feedback window, so; UE can't confirm that losing of packet taken place in subframe 3 attention or does not dispatch the base station in this subframe, because it only is to carry out on subframe 2 in subframe 0 that above-mentioned time domain merges; In practical application, if received corresponding packet on the subframe 4, then the UE feedback information that carries out the time domain union operation also will comprise the feedback information on the subframe 4; For this kind situation, the embodiment of the invention explains that no longer separately such variation does not influence protection scope of the present invention.
