Abstract

An embodiment of the invention discloses a channel resource determination method of ACK/NACK feedback information and equipment. Through applying a technical scheme of the embodiment, alternative channel resource can be determined in an application scene of time domain merging employing a PUCCH format 1b with channel selection scheme. A determination problem of channel resource needed by channel selection is solved when a terminal device employs the PUCCH format 1b with channel selection scheme to transmit ACK/NACK feedback information which is subjected to downlink inter-subframe merging. A situation that the alternative channel resource can not be determined for the scene according to the prior art is avoided. In a scene that the ACK/NACK feedback information is larger than 4 bits and the time domain merging is applied, transmission of the ACK/NACK feedback information through the PUCCH format 1b with channel selection scheme is realized. The method and the equipment are mainly suitable for a TDD system.

Description

The channel resource of ACK/NACK feedback information is confirmed method and apparatus

Technical field

The present invention relates to communication technical field, particularly a kind of channel resource of ACK/NACK feedback information is confirmed method and apparatus.

Background technology

For long-term evolution multi-carrier system, for supporting that such as 100MHz, a kind of possibly be the frequency spectrum that directly distributes the 100M bandwidth, as shown in Figure 1 than LTE (Long Term Evolution, Long Term Evolution) the wideer system bandwidth of system; A kind of possibly be with distributing to some spectrum aggregatings of existing systems; Gather into big bandwidth and supply with the long-term evolution multi-carrier system use; The up-downgoing carrier wave can asymmetricly dispose in the system at this moment; Be that the user may take N >=1 carrier wave and carries out downlink transfer, M >=1 carrier wave carries out uplink, and is as shown in Figure 2.

LTE-A (Long Term Evolution Advanced; Senior Long Term Evolution) system confirms to support 5 carrier waves to carry out polymerization at most at present; A LTE-A UE (User Equipment; Subscriber equipment) need be at ACK (Acknowledgement, positive acknowledgement)/NACK (Negative Acknowledgement, the NACK) feedback information of corresponding a plurality of descending carriers of same sub-frame of uplink internal feedback and descending sub frame.Confirm in the UTE-A system at present; The ACK/NACK information bit of UE feedback is confirmed based on the descending carrier of configuration and the transmission mode of each descending carrier; Promptly at FDD (Frequency Division Duplex; FDD) in the system; UE needs feedback bit ACK/NACK at a sub-frame of uplink, and wherein Ci is the code word number (C=1 during the single codeword transmission, C=2 during many codeword transmission) of each descending carrier; The transmission mode (being the code word number) of different descending carriers can be different, and N is a UE configurating downlink carrier number; At TDD (Time Division Duplex; Time division duplex) in the system; UE needs feeding back ACK/NACK to feed back M bit ACK/NACK at a sub-frame of uplink; Wherein M is the descending sub frame quantity that UE need carry out the ACK/NACK feedback at same sub-frame of uplink; For different uplink-downlink configuration and sub-frame of uplink, the value of M is different, i.e. the quantity of each hurdle K in the table 1.Corresponding same sub-frame of uplink carries out a plurality of descending sub frames of ACK/NACK feedback, abbreviates " feedback window " hereinafter as.

Table 1 Downlink association set index K:{k ₀, k ₁... K _M-iFor TDD

In the LTE-A system; Confirmed can adopt PUCCH (Physical Uplink Control Channel for being no more than 4 bit ACK/nack message; Physical Uplink Control Channel) format 1b with channel selection transmission plan; This scheme is carried out channel through UE at a plurality of channel resources and is selected transmission to distinguish different ACK/NACK feedback information states; Wherein, ACK/NACK mapping form is exactly the mapping that is used for realizing ACK/NACK information to be feedback and actual channel transmission information (being 4 constellation point of PUCCH format 1b QPSK modulation) and transmission channel.For 2,3,4 bit ACK/NACK feedback information, need 2,3,4 PUCCH format 1a/1b uplink control channel resources respectively.

In LTE-A TDD system; Because PUCCH Format 1b with channel selection transmission plan is supported 4 bit ACK/NACK feedback at most; When UE needs the ACK/NACK bit number of feedback to surpass 4 in a sub-frame of uplink, need carry out ACK/NACK information and merge (bundling) to reduce the bit number of ACK/NACK feedback information.UE can merge (claiming that again time domain merges), the L bit ACK that obtains merging/NACK feedback information b to the pairing ACK/NACK feedback information of the packet that receives in a plurality of descending sub frames in the feedback window on the descending carrier of a configuration ₀, b ₁... b _L-1,, as shown in Figure 3, wherein, N≤L≤2N, N are the descending carrier number of UE polymerization.If the descending carrier of configuration is many codeword transmission pattern; UE needs the descending carrier of 2N-L configuration is carried out the space merging; Promptly the ACK/NACK feedback information that receives a plurality of code words in the same descending sub frame on this descending carrier is merged and (claim that again the space merges; Spatial bundling), can preferentially merge descending auxilliary carrier wave.The feedback information state comprises ACK (the correct packet that receives), NACK (packet that mistake receives) and DTX (packet of losing or not dispatching).In the merging process; If the descending carrier that UE can judge current configuration in the feedback window internal memory downlink data packet loss (PDCCH that the indication semi-continuous scheduling discharges and the losing of PDSCH with dynamic PDCCH scheduling can be judged through DAI; Losing of SPS packet can be judged through the SPS service period); Perhaps UE does not receive any packet on the descending carrier of current configuration in feedback window, then this descending carrier is generated DTX as the feedback information that merges; If UE judges current configurating downlink carrier wave and in feedback window, do not have the downlink data packet loss, and the feedback information of at least one packet that receives on this descending carrier is NACK, then this descending carrier generated NACK as the feedback information that merges; If UE judges current configurating downlink carrier wave and in feedback window, do not have the downlink data packet loss, and the feedback information of all packets that receive on this descending carrier all be ACK, then this descending carrier generated the feedback information of ACK as merging.

When considering that carrying out time domain merges; Because UE can't know the actual schedule situation (be the descending sub frame/number-of-packet of base station actual schedule) of base station in a plurality of descending sub frames; Therefore can't judge whether the descending sub frame that is scheduled at last has data-bag lost; Thereby make ACK/NACK information after the merging of UE feedback can not reflect the reception condition of actual schedule data really, cause the misinterpretation of base station, the reliability of influence transmission the ACK/NACK feedback information.Understand differently and cause problem in order to solve data-bag lost causes in the merging process UE and base station, can adopt the Merge Scenarios shown in Fig. 4 A and 4B, 1) shown in Fig. 4 A, the DAI among the DL grant does as a wholely (to be designated as DAI _Total), be used to indicate in the feedback window sum of the PDSCH that is dispatched till the current descending sub frame; 2) shown in Fig. 4 B, the DAI that reuses among the LTE TDD DL grant (is designated as DAI _f), be used to indicate the PDSCH sum that has dynamic PDCCH in the current sub-downlink frame on the different descending carriers.Pass through DAI; Whether the data packet transmission in the middle of UE can judge loses; The descending sub frame number with dynamic PDCCH that UE will receive in feedback window (PDCCH that comprises dynamic dispatching PDSCH transmission, and the PDCCH of indication SPS PDSCH resource release) is as 1 or 2 bit overhead bits

and the ACK/NACK feedback information cascade transmission that merges.Like this, the base station can be through back 1～2 bit information in the ACK/NACK feedback information that receives, and whether the packet of judging last scheduling loses that (overhead bit is DAI _tDuring information) or judge whether there is data-bag lost in the feedback window (overhead bit is the descending sub frame number that the UE actual reception arrives in the feedback window), thus avoid merging the unnecessary re-transmission in the transmission, improve system transmissions efficient.

In the process that realizes the embodiment of the invention, the applicant finds that there is following problem at least in prior art:

In the LTE-A system, the reservation of implicit information channel resource is all only reserved to the PDCCH on the descending carrier of pairing with it on each up-link carrier.So-called implicit information channel resource; It is exactly the uplink control channel resource of control information zone (each CCE) reservation of a corresponding fixing descending carrier on the up-link carrier; UE is through minimum CCE (the Control Channel Element) numbering of the descending control signaling (PDCCH) that on this descending carrier, sends; All can calculate and obtain an available uplink control channel resource, abbreviate " implicit information channel resource " or " dynamic channel resource " as.In addition, downlink data transmission also possibly be the business that does not have corresponding PDCCH, i.e. SPS packet.Descending SPS transmission only occurs on the downlink main carrier to carry, by the PDCCH triggering that indication SPS transmission activates, can transmit according to fixing cycle and resource distribution after the triggering, and behind the PDCCH that receives indication SPS transmission release, this SPS end of transmission.Therefore; There is not corresponding PDCCH in the transmission course after SPS is triggered; Therefore do not have the implicit information channel resource, each pairing channel resource of SPS data packet transmission is all identical, is the indicated semi-static channel resource of TPC territory among the PDCCH of indication SPS transmission activation.If the base station need change the SPS transmission configuration, as changing transmission bandwidth etc., then can send a dynamic PDCCH of corresponding SPS transmission, if UE receives this PDCCH, then definite this descending SPS transmission will be transmitted according to the configuration of this PDCCH indication.Consider that PUCCH can only be at up main carrier (UL PCC in the LTE-A system; Uplink primary component carrier) sends; And UL PCC is only to downlink main carrier to carry (DL PCC; Downlink primary component carrier) carries out resource reservation; So UE can only obtain the implicit information channel resource of reservation on the UL PCC through the PDCCH of transmission on the DL PCC, so the required channel resource of PUCCH format 1b with channel selection not necessarily can obtain from the implicit information channel resource.In addition; UE maybe be in feedback window receives the PDCCH that transmits on the downlink main carrier to carry in a plurality of descending sub frames on descending carrier; And then obtain a plurality of implicit information channel resources; Then UE needs also further to confirm which channel resource the pairing channel resource of this descending carrier is specially; When not having the PDCCH that transmits on the downlink main carrier to carry on this descending carrier in the feedback window, the pairing channel resource of this descending carrier can be the indicated semi-static channel resource in resource indication territory (ARI) of RRC configuration or PDCCH.

At present, in existing technology, also there is not corresponding solution.

In practical application, this step adopts PUCCH format 1b with channel selection transmission plan; According to ACK/NACK mapping form; L+T bit feedback bit is being selected corresponding channel resource in L+T channel resource at the most; And select corresponding modulation symbol (4 QPSK constellation point of PUCCH format 1b), on the channel resource of selecting, send corresponding modulation symbol.

Wherein, ACK/NACK mapping form is used for representing the corresponding relation of the channel resource of ACK/NACK feedback information and actual transmissions and the modulation symbol of transmission (being 4 constellation point of PUCCH format 1b QPSK modulation).

In said process, the ACK in the ACK/NACK mapping form representes correctly to receive packet; NACK representes that mistake receives packet; DTX representes data-bag lost or free of data packet scheduling.

Corresponding, in base station side, the above-mentioned identical rule of base station applies is carried out confirming of channel resource; And select corresponding channel resources to carry out the reception of ACK/NACK feedback information; It is pointed out that because base station side can not be confirmed the situation of the data-bag lost of UE end, so; Confirm difference to occur at channel resource in such cases with the processing procedure of aforesaid terminal equipment side; But, because terminal equipment side can not select the pairing channel resource of descending sub frame of data-bag lost (corresponding ACK/NACK feedback information is DTX) to carry out the transmission of ACK/NACK feedback information, so; Even terminal equipment and base station there are differences for the determined channel resource of the descending sub frame of data-bag lost, can not occur the ACK/NACK feedback information yet and receive wrong situation.

At this, for the no longer repeat specification of processing procedure of base station side.

Below, the application scenarios in conjunction with concrete describes the technical scheme that the embodiment of the invention proposed.

Embodiment 1

UE has disposed 2 descending carriers; Descending carrier 1 is a downlink main carrier to carry; Descending carrier 1 adopts many codeword transmission pattern; Descending carrier 2 adopts the single codeword transmission mode, and M=4 promptly needs

bit supplementary; L=2 then, the i.e. feedback information that merges of corresponding 1 bit of each descending carrier; Descending

sub frame

1,2,4 has been dispatched at descending carrier 1 in the base station, has dispatched descending

sub frame

1,2,3,4 at descending carrier 2, and is as shown in Figure 6, adopts the method one among the step S503, and then the flow process of transferring ACK/NACK is following:

The UE end:

UE need to confirm feedback 12 bit ACK/NACK according to the transmission mode of 2 descending carrier configurations and each descending carrier, greater than 4 bits, therefore need carry out ACK/NACK and merge;

Because L=2 needs that downlink main carrier to carry is carried out the space and merges;

Candidate's resource that UE adopts pre-configured

the individual channel resource of RRC signaling to select as channel;

On descending carrier 1, UE judges descending sub frame 2 packet losses according to DAI information, and the DTX that produces the merging of 1 bit is as feedback information; On descending carrier 2, UE judges that according to DAI information descending sub frame 1 does not have scheduling, according to the data of receiving in the descending

sub frame

2,3,4, produces 1 bit NACK as its feedback information; UE produces 2 bit supplementarys according to the descending sub frame number with dynamic PDCCH that receives, " 11 " in the example corresponding relation as shown in table 2, and expression UE has received 4 descending sub frames with dynamic PDCCH;

Table 2 supplementary mapping signal table

The final 4 bit feedback bits that generate of UE; Adopt PUCCH format 1b with channel selection transmission plan; According to ACK/NACK mapping form; In the channel resource of 4 RRC configurations, confirm corresponding channel resource, and confirm corresponding modulation symbol, on selected channel resource, send corresponding modulation symbol;

Base station end:

The base station confirms that according to the transmission mode of 2 descending carrier configurations and each descending carrier UE need feed back 12 bit ACK/NACK, greater than 4 bits, confirms that therefore UE merges the ACK/NACK feedback information;

Pass through pre-configured 4 the PUCCH format 1a/1b channel resources of RRC signaling according to

base station;

4 pre-configured channel resources are detected in the base station, obtain 4 bits and receive information; Because M=4, preceding 2 bit informations of base station judges are the amalgamation result of the ACK/NACK feedback information of the packet on descending carrier 1 and the carrier wave 2, back 2 bit informations are supplementary, and judge that through supplementary UE does not exist last descending sub frame to lose; Retransmission data packet may is confirmed according to pooling information in the base station.

Embodiment 2:

UE has disposed 3 descending carriers; Descending carrier 1 is a downlink main carrier to carry; Each descending carrier all adopts the single codeword transmission mode, and M=2 promptly needs

bit supplementary; L=3 then, the i.e. feedback information that merges of corresponding 1 bit of each descending carrier; Descending

sub frame

1,2 has all been dispatched at descending

carrier

1,2,3 in the base station; Carrier dispatching is striden in support; The transfer of data of descending carrier 2 is dispatched by the PDCCH on the downlink main carrier to carry; Transfer of data on the descending carrier 3 adopts method two or method three by the scheduling of the PDCCH on the descending carrier 3, and then the flow process of transferring ACK/NACK is following:

(1) situation 1: the descending sub frame of downlink main carrier to carry 1 is for existing dynamic PDCCH (can be the PDCCH that activates SPS, also can be the PDCCH of the dynamic PDSCH of scheduling) in the PDSCH transmission of SPS and the descending sub frame 1, and as shown in Figure 7, then the flow process of transferring ACK/NACK is following:

When adopting method two

The UE end:

Because UE has received the PDCCH of dispatching downlink main carrier and descending carrier 2 on downlink main carrier to carry; Although the descending sub frame on the downlink main carrier to carry 1 is SPS PDSCH; But there is corresponding dynamic PDCCH, therefore can confirms the channel resource of downlink main carrier to carry and descending carrier 2 correspondences according to the method A in the method two or B:

When adopting the method A in the method two: because the packet of DAI=0 is the packet in the descending sub frame 1 on the downlink main carrier to carry, then UE confirms that the pairing channel resource of downlink main carrier to carry is 1 corresponding dynamic channel resource of CCE lowest number of the PDCCH of dispatching downlink main carrier ascending-descending subframes 1; Because the packet of DAI=0 is the packet in the descending sub frame 1 on the descending carrier 2; And this descending sub frame packet loss; Then UE can uncertain descending carrier 2 pairing channel resources (because the feedback information of descending carrier 2 is DTX; UE can not adopt descending carrier 2 corresponding channel resources to send), perhaps UE confirms channel resource according to following method B;

During employing method B: owing to receive first subframe of data on the downlink main carrier to carry is descending sub frame 1, and then UE confirms that the pairing channel resource of downlink main carrier to carry is 1 corresponding dynamic channel resource of CCE lowest number of the PDCCH of dispatching downlink main carrier ascending-descending subframes 1; Because receiving first descending sub frame of data on the descending carrier 2 is descending sub frame 2, then UE confirms that descending carrier 2 pairing channel resources are 1 corresponding dynamic channel resource of CCE lowest number of the PDCCH of dispatching downlink carrier wave 2 ascending-descending subframes 2;

Because the PDCCH of dispatching downlink carrier wave 3 is in descending carrier 3 (descending auxilliary carrier wave) transmission, then descending carrier 3 pairing channel resources are 1 semi-static channel resource of ARI indication of the PDCCH of dispatching downlink carrier wave 3 ascending-descending subframes;

UE confirms that 1 pre-configured semi-static channel resource of RRC signaling is the pairing channel resource of 1 bit supplementary;

On downlink main carrier to carry, UE is according to 2 descending sub frame data that receive, and the ACK that produces the merging of 1 bit is as feedback information; On descending carrier 2, UE judges descending sub frame 1 packet loss according to DAI, produces 1 bit DTX as feedback information; On descending carrier 3, UE produces 1 bit NACK as feedback information according to 2 descending sub frame data that receive; UE produces 1 bit supplementary according to the descending sub frame number with dynamic PDCCH that receives, " 1 " in the example corresponding relation as shown in table 3, and expression UE has received 2 descending sub frames with dynamic PDCCH;

The final 4 bit feedback bits that generate of UE; Adopt PUCCH format 1b with channel selection transmission plan; According to ACK/NACK mapping form; In 4 channel resources, confirm corresponding channel resource, and confirm corresponding modulation symbol, on selected channel resource, send corresponding modulation symbol;

carrier

1,2 and 3, and back 1 bit information is a supplementary, and judge that through supplementary UE does not exist last descending sub frame to lose; The retransmission operation of each descending carrier ascending-descending subframes is confirmed in the base station according to the pairing merging feedback information of each descending carrier; Wherein, Can judge the descending carrier of packet loss for UE, base station and UE maybe be inconsistent to the understanding of channel resource, for example; Because there is transfer of data in the base station at the descending sub frame 1 of descending carrier 2; Therefore the base station confirms that descending carrier 2 pairing channel resources are 1 corresponding dynamic channel resource of CCE lowest number of the PDCCH of dispatching downlink carrier wave 2 ascending-descending subframes 1, and is inconsistent with UE, but because UE can judge descending carrier 2 packet losses; Can not select descending carrier 2 pairing channel resources to transmit, therefore not influence the correct reception of feedback information;

During employing method three

The UE end:

Because UE has received the PDCCH of dispatching downlink main carrier and descending carrier 2 on downlink main carrier to carry; Although the descending sub frame on the downlink main carrier to carry 1 is SPS PDSCH; But have corresponding dynamic PDCCH, therefore can confirm the channel resource of downlink main carrier to carry and descending carrier 2 correspondences according to the method A in the method two or B: concrete grammar is with the description in situation 1 method two;

Because the PDCCH of dispatching downlink carrier wave 3 transmits at descending carrier 3 (descending auxilliary carrier wave); Be that descending carrier 3 does not exist corresponding dynamic channel resource, UE confirms that 2 pre-configured semi-static channel resources of RRC signaling are descending carrier 3 and the pairing channel resource of 1 bit supplementary;
