Abstract

The embodiment of the invention discloses an acknowledgement ACK/negative acknowledgement (NACK) feedback information transmission method and ACK/NACK feedback information transmission equipment. By the technical scheme provided by the embodiment of the invention, under the condition of only receiving a semi-persistent scheduling physical downlink shared channel (SPS PDSCH) and a physical downlink control channel (PDCCH) with the downlink assignment index (DAI) value of 1 in a feedback window by terminal equipment, if the terminal is required to report ACK/NACK feedback information together with other user class identifier (UCI) information in a corresponding uplink sub-frame, the terminal equipment transmits to-be-fed-back 2-bit feedback information corresponding to the spatially-combined ACK/NACK feedback information by using physical uplink control channel (PUCCH) resources corresponding to the other UCI, thereby feeding base station configuration back by using PUCCH format 3 resources. When corresponding PUCCH format 3 resources cannot be acquired because the terminal equipment only receives the SPS PDSCH and the PDCCH with the downlink (DL) DAI value of 1 and is required to transmit a scheduling request in the corresponding uplink sub-frame at the same time, a corresponding scheme is provided to ensure the normal transmission of the corresponding ACK/NACK feedback information.

Description

The transmission method of ACK/NACK feedback information and equipment

Technical field

The present invention relates to communication technical field, particularly a kind of transmission method of ACK/NACK feedback information and equipment.

Background technology

For LTE(Long Term Evolution, Long Term Evolution) TDD(Time Division Duplex, time division duplex) system, UE(User Equipment, subscriber equipment, i.e. terminal equipment) may in a sub-frame of uplink, feed back the pairing ACK(Acknowledgement of a plurality of descending sub frames, positive acknowledgement)/NACK(Negative Acknowledgement, Negative Acknowledgement) information, promptly UE finishes descending sub frame N-kOn data demodulation, decoding after, will be at sub-frame of uplink nWhether go up data on this descending sub frame of base station feedback needs the signaling (being ACK/NACK) that retransmits, k∈ K, set KThe uplink-downlink configuration and the concrete subframe numbering of value and system relevant, as shown in table 1.

Wherein, promptly be corresponding same sub-frame of uplink in " feedback window " described in the application's the associated description KIndividual descending sub frame.

In the LTE system, up SR(Scheduling Requset, dispatch request) and cycle CSI(Channle State Information channel quality information) periodically feed back.If UE will send SR, then can only the SR in configuration cycle report on the subframe to send; Cycle CSI also can only report subframe to send by the CSI in configuration cycle, and its employed uplink channel resources is pre-assigned by high level.

LTE-A(Long Term Evolution Advanced, senior Long Term Evolution) in the system, PUCCH(Physical Uplink Control Channel, Physical Uplink Control Channel can configuration UE be used in the base station) the format(form) 3 transmission many bit ACK/NACK feedback informations.At this moment, descending Allotment Serial Number DL(Downlink in the downlink main carrier to carry in the feedback window, descending) DAI(Downlink Assignment Index, descending distribution index) value is 1 PDCCH(Physical Downlink Control Channel, Physical Downlink Control Channel) the TPC(Transport Power Control in, transmitting power control) territory is used for load power control signaling, and DL DAI value is permitted greater than DL grant(all on 1 PDCCH and the subcarrier on the downlink main carrier to carry) in the TPC territory as ARI(ACK/NACK Resource Indicator, the indication of ACK/NACK resource), promptly indicate UE to carry out the resource that ACK/NACK feeds back employed PUCCH format 3, and in the same feedback window, the indicated ARI of different PDCCH is identical.

If carrying out the sub-frame of uplink of ACK/NACK feedback is again that SR reports subframe simultaneously, so:

If UE has only received SPS(Semi-persistent scheduling in feedback window, semi-continuous scheduling) PDSCH(Physical Downlink Shared Channel, Physical Downlink Shared Channel), and SR is that positive(determines), then UE is in the SR PUCCH transmitted over resources of high level configuration d(0)=1(SPS PDSCH corresponds to NACK) or d(0)=-1(SPS PDSCH corresponds to ACK), wherein d(0) is the modulation symbol of feedback information correspondence.

If UE has only received SPS PDSCH in feedback window, and SR is that negative(negates), then UE is in the SPS PUCCH transmitted over resources by the high level configuration d(0)=1(SPS PDSCH corresponds to NACK) or d(0)=-1(SPS PDSCH corresponds to ACK), wherein d(0) is the modulation symbol of feedback information correspondence.

If UE only received that in feedback window DL DAI value is 1 PDCCH, and SR is positive, and then UE is in the SR PUCCH transmitted over resources of high level configuration d(0)=1(DL DAI value is that 1 PDCCH corresponds to NACK) or d(0)=-1(DL DAI value is that 1 PDCCH corresponds to ACK), wherein d(0) is the modulation symbol of feedback information correspondence.

If UE only received that in feedback window DL DAI value is 1 PDCCH, and SR is negative, and then UE is 1 the corresponding PUCCH format of PDCCH 1a/1b transmitted over resources in DL DAI value d(0)=1(DL DAI value is that 1 PDCCH corresponds to NACK) or d(0)=-1(DL DAI value is that 1 PDCCH corresponds to ACK), wherein d(0) is the modulation symbol of feedback information correspondence.

If UE has received DL DAI value greater than 1 PDCCH in feedback window, then UE uses PUCCH format 3 many bit ACK/NACK of feedback and SR information on the resource of ARI indication, and wherein ACK/NACK and SR information will be carried out combined coding.

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

For Rel-10(version 10) UE, if base station configuration is used PUCCH format 3 transferring ACKs/NACK feedback information, and UE has only received that SPS PDSCH and DL DAI value are 1 PDCCH in the feedback window, and in the sub-frame of uplink of correspondence, send dispatch request simultaneously, this moment, UE can't obtain corresponding PUCCH format 3 resources, and how carrying out ACK/NACK and SR/CSI feedback does not also have clear and definite scheme.

Embodiment

As stated in the Background Art, for Rel-10 UE, determined at present to dispose and used PUCCH format 3 transferring ACKs/NACK feedback information, but in the feedback window, only receive that SPS PDSCH and DAI value are 1 PDCCH for UE, and being SR, the sub-frame of uplink of corresponding feeding back ACK/NACK feedback information reports subframe, and it is the situation of positive state that SR reports subframe, and the feedback scheme of ACK/NACK feedback information and SR is not determined as yet.

In like manner, for the sub-frame of uplink of other types, for example CSI reports subframe, if the situation that also exists schedule information and ACK/NACK feedback information to transmit simultaneously, the transmission plan of ACK/NACK feedback information does not all have to provide in existing technical scheme so, accordingly.

Based on above reason, the embodiment of the invention has provided a kind of transmission method of ACK/NACK feedback information of this kind of correspondence situation.

As shown in Figure 1, 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:

When step S101, the value that receives only SPS PDSCH that the base station sends and DL DAI when terminal equipment in feedback window were 1 PDCCH, terminal equipment judged the value of SPS PDSCH and DL DAI is whether 1 the pairing ACK/NACK feedback information of PDCCH need report by the UCI with other in the sub-frame of uplink of correspondence.

If judged result is for reporting together, execution in step S102;

If judged result reports together for not needing, execution in step S104.

In the operation of reality, based on different application scenarioss, the deterministic process of this step also is divided into multiple concrete situation, in the present embodiment, specifically being specially SR with the sub-frame of uplink of correspondence reports subframe or CSI to report the situation of subframe to be example, corresponding processing procedure is described.

Situation one, determine corresponding sub-frame of uplink when terminal equipment and be specially SR when reporting subframe.

Terminal equipment is judged the state of SR information.

When terminal equipment judged that SR information is the positive state, terminal equipment determined that judged result is to report together, thus execution in step S102.

When terminal equipment judged that SR information is the negative state, terminal equipment determined that judged result reports together for not needing, thus execution in step S104.

Situation two, determine corresponding sub-frame of uplink when terminal equipment and be specially CSI when reporting subframe.

Terminal equipment is judged the state of CSI information and ACK/NACK information.

When transmitting when terminal equipment judges that CSI information and ACK/NACK information of same are supported in the higher level parameters configuration, terminal equipment determines that judged result is to report together, thus execution in step S102.

When transmitting when terminal equipment judges that CSI information and ACK/NACK information of same are not supported in the higher level parameters configuration, terminal equipment determines that judged result reports together for not needing, thus execution in step S104.

Need further be pointed out that; it all is concrete examples that the embodiment of the invention provides for convenience of description that above-mentioned SR reports subframe and CSI to report subframe; sub-frame of uplink for other types; also can handle based on similar thinking, the difference of concrete sub-frame of uplink type can't influence protection scope of the present invention.

Step S102, terminal equipment are that 1 the pairing ACK/NACK feedback information of PDCCH carries out the space and merges to the value of SPS PDSCH and DL DAI, obtain 2 bits ACK/NACK information to be feedback.

Step S103, terminal equipment are on the pairing Physical Uplink Control Channel PUCCH of other UCI resource, to base station transmits 2 bits feedback information to be transmitted.

Wherein, 2 bits feedback information to be transmitted and the satisfied default corresponding relation of ACK/NACK feedback information to be feedback.

For to the convenient explanation of above-mentioned qualifications, the embodiment of the invention satisfies the corresponding relation of presetting for 2 bits feedback information to be transmitted in this step and ACK/NACK feedback information to be feedback and is exemplified below:

When (1) value that is specially SPS PDSCH corresponding A CK and DL DAI when ACK/NACK feedback information to be feedback was the corresponding NACK of 1 PDCCH, corresponding 2 bits feedback information to be transmitted was specially b(0), b(1)=1,1, its further corresponding transmitting feedback information, promptly modulation symbol is specially d(0)=-1.

When (2) value that is specially corresponding NACK of SPS PDSCH and DL DAI when ACK/NACK feedback information to be feedback was the corresponding NACK of 1 PDCCH, corresponding 2 bits feedback information to be transmitted was specially b(0), b(1)=0,0, its further corresponding transmitting feedback information, promptly modulation symbol is specially d(0)=1.

When (3) value that is specially SPS PDSCH corresponding A CK and DL DAI when ACK/NACK feedback information to be feedback was 1 PDCCH corresponding A CK, corresponding 2 bits feedback information to be transmitted was specially b(0), b(1)=1,0, its further corresponding transmitting feedback information, promptly modulation symbol is specially d(0)=j.

When (4) value that is specially corresponding NACK of SPS PDSCH and DL DAI when ACK/NACK feedback information to be feedback was 1 PDCCH corresponding A CK, corresponding 2 bits feedback information to be transmitted was specially b(0), b(1)=0,1, its further corresponding transmitting feedback information, promptly modulation symbol is specially d(0)=-j.

Based on above-mentioned explanation, the content of concrete corresponding relation can be adjusted according to actual needs, and under the situation that does not influence the corresponding effect of content, the content change of concrete corresponding relation can't influence protection scope of the present invention.

Further, need to carry out following qualification in the technical scheme proposed by the invention:

When the corresponding identical ACK/NACK feedback information of SPS PDSCH, the value of DL DAI is 1 the corresponding NACK of PDCCH, receives only the situation of SPS PDSCH with terminal equipment, and correspondence has the transmitting feedback information of identical value.

In actual applications, for above-mentioned further qualification, contrast four kinds of above-mentioned rules of correspondence, as can be seen, above-mentioned (1) and (2) are the aforesaid situation that needs qualification, because corresponding qualification explanation can draw:

When ACK/NACK feedback information to be feedback is specially SPS PDSCH corresponding A CK, if it is that 1 PDCCH takes defeat that terminal equipment receives only the value of SPS PDSCH(DL DAI), then corresponding transmitting feedback information situation is identical with (1), and promptly Dui Ying 2 bits feedback information to be transmitted is specially b(0), b(1)=1,1, its further corresponding transmitting feedback information, promptly modulation symbol is specially d(0)=-1.

In like manner, when ACK/NACK feedback information to be feedback is specially SPS PDSCH correspondence NACK, if it is that 1 PDCCH takes defeat that terminal equipment receives only the value of SPS PDSCH(DL DAI), then corresponding transmitting feedback information situation is identical with (2), and promptly Dui Ying 2 bits feedback information to be transmitted is specially b(0), b(1)=0,0, its further corresponding transmitting feedback information, promptly modulation symbol is specially d(0)=1.

This shows, in aforesaid four in the corresponding relation, preceding two kinds of corresponding relations (1) and (2) need particular determination, then two kinds of corresponding relations (3) and (4) then can exchange or use other corresponding relation, concrete reason explanation is set forth in follow-up embodiment, in this no longer repeat specification.

In addition, in the application scenarios of reality, the operation of this step is specifically as follows:

Determine corresponding sub-frame of uplink when terminal equipment and be specially SR when reporting subframe, terminal equipment uses PUCCH format 1b to base station transmits 2 bits feedback information to be transmitted on the SR PUCCH resource of high level configuration;

Determine corresponding sub-frame of uplink when terminal equipment and be specially CSI when reporting subframe, terminal equipment uses PUCCH format 2a/2b to base station transmits 2 bits feedback information to be transmitted on the CSI PUCCH resource of high level configuration.

Certainly; this is the given a kind of concrete operational instances of the embodiment of the invention; if other forms of resource format can be finished corresponding laser propagation effect equally, then also can adopt other resource format, such variation does not influence protection scope of the present invention.

Step S104, terminal equipment are on ACK/NACK PUCCH resource, to base station transmits ACK/NACK feedback information to be feedback.

Correspondingly, the schematic diagram of the processing procedure of the transmission method base station side of the ACK/NACk feedback information that the embodiment of the invention proposed specifically may further comprise the steps as shown in Figure 2:

Step S201, base station in feedback window are 1 PDCCH to the value of terminal equipment scheduling SPS PDSCH and DL DAI.

The feedback information that step S202, base station send by PUCCH resource receiving terminal apparatus.

With reference to the explanation among the aforesaid step S101, in the operation of reality, based on different application scenarioss, the receiving course of this step also is divided into multiple concrete situation, in the present embodiment, equally with step S101 in corresponding SR report subframe or CSI to report the situation of subframe to be example, corresponding processing procedure is described.

Situation one, determine that corresponding sub-frame of uplink is specially SR and reports subframe when terminal equipment, and when adopting corresponding scheme to carry out transmission of feedback information.

In the application scenarios of reality, the specific implementation of step S202 in such cases can be divided into following two kinds of methods according to the difference of preferentially carrying out the resource type of input:

Method one, preferentially detect SR PUCCH.

As shown in Figure 3, the method one specifically comprises following handling process:

Input is carried out in step S301, base station on SR PUCCH.

When detecting signal, execution in step S302;

When not detecting signal, execution in step S303.

Step S302, base station determine that it is the positive state that SR reports subframe, and according between detected information and the ACK/NACK feedback information to be feedback satisfy default corresponding relation, the value of determining SPS PDSCH and DL DAI is 1 the pairing ACK/NACK feedback information of PDCCH.

Step S303, base station determine that it is the negative state that SR reports subframe, and on ACK/NACK PUCCH, method according to non-SR subframe is carried out input, determines that according to connecing the information that measures the value of SPS PDSCH and DL DAI is 1 the pairing ACK/NACK feedback information of PDCCH.

Method two, preferentially detect ACK/NACK PUCCH.

As shown in Figure 4, the method two specifically comprises following handling process:

Input is carried out in step S401, base station on ACK/NACK PUCCH.

When detecting signal, execution in step S402;

When not detecting signal, execution in step S403.

Step S402, base station determine that it is the negative state that SR reports subframe, and determine that according to connecing the information that measures the value of SPS PDSCH and DL DAI is 1 the pairing ACK/NACK feedback information of PDCCH.

Input is carried out in step S403, base station on SR PUCCH.

In follow-up processing procedure, the base station is 1 the pairing ACK/NACK feedback information of PDCCH according to connecing value that the result who measures determines SPS PDSCH and DL DAI.

When detecting signal, execution in step S404;

When not detecting signal, execution in step S406.

Step S404, base station determine that it is the positive state that SR reports subframe.

Step S405, base station according to detected information and and ACK/NACK feedback information to be feedback between satisfy default corresponding relation, the value of determining SPS PDSCH and DL DAI is 1 the pairing ACK/NACK feedback information of PDCCH.

Step S406, base station judge whether terminal equipment correctly receives SPS activation of service signaling.

If the base station is determined terminal equipment and is correctly received SPS activation of service signaling, then execution in step S407;

If the base station be can not determine terminal equipment and is correctly received SPS activation of service signaling, then execution in step S408.

Step S407, base station determine that the feedback information of terminal equipment is not correctly received.

Step S408, base station determine that the feedback information of terminal equipment is not correctly received, or definite SR to report subframe be the negative state, and terminal equipment is for receiving downlink data transmission.

Situation two, determine that corresponding sub-frame of uplink is specially CSI and reports subframe when terminal equipment, and when adopting corresponding scheme to carry out transmission of feedback information.

In such cases, input is carried out in the base station on CSI PUCCH resource, and the default corresponding relation that is satisfied according to detected 2 bits feedback information to be transmitted and ACK/NACK feedback information to be feedback, the value of determining SPS PDSCH and DL DAI is 1 the pairing ACK/NACK feedback information of PDCCH.

For this kind situation, the processing procedure in situation one wants simple, can realize with reference to corresponding actual thinking, no longer specifies in the present embodiment.

Corresponding with the explanation among the aforesaid step S103, in the explanation of above-mentioned step S302, step S405 and situation two, satisfy default corresponding relation between the detected information of base station institute foundation and the ACK/NACK feedback information to be feedback, promptly corresponding resolution rules specifically comprises:

(1) transmitting feedback information when detected information correspondence is specially d(0)=-1 o'clock, its pairing 2 bits feedback information to be transmitted is b(0), b(1)=1,1, further, can determine that corresponding ACK/NACK feedback information to be feedback is specially SPS PDSCH corresponding A CK, the value of DL DAI is 1 the corresponding NACK of PDCCH.

(2) transmitting feedback information when detected information correspondence is specially d(0)=1 o'clock, its pairing 2 bits feedback information to be transmitted is b(0), b(1)=0,0, further, can determine that corresponding ACK/NACK feedback information to be feedback is specially the corresponding NACK of SPS PDSCH, the value of DL DAI is 1 the corresponding NACK of PDCCH.

(3) transmitting feedback information when detected information correspondence is specially d(0)=during j, its pairing 2 bits feedback information to be transmitted is b(0), b(1)=1,0, further, can determine that corresponding ACK/NACK feedback information to be feedback is specially SPS PDSCH corresponding A CK, the value of DL DAI is 1 the corresponding A CK of PDCCH institute.

(4) transmitting feedback information when detected information correspondence is specially d(0)=-during j, its pairing 2 bits feedback information to be transmitted is b(0), b(1)=0,1, further, can determine that corresponding ACK/NACK feedback information to be feedback is specially the corresponding NACK of SPS PDSCH, the value of DL DAI is 1 the corresponding A CK of PDCCH institute.

Similar with the explanation among the step S103, preceding two kinds of corresponding relations need to limit, and back two kinds of corresponding relations can exchange or change.

In the application scenarios of reality; the default corresponding relation of the above-mentioned applied step S103 of terminal equipment; and the particular content of the applied resolution rules in base station all can be adjusted according to actual needs; but as long as guarantee that the understanding of terminal equipment side and base station side is consistent; and do not influence the judgement effect of emphasizing the corresponding relation that limits in the embodiment of the invention and get final product, such variation does not influence protection scope of the present invention.

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

With reference to aforesaid explanation, specifically reporting subframe with SR is example explanation the technical program, and in this scene, base station configuration UE is used PUCCH format 3 transferring ACKs/NACK feedback information.

If in concrete processing procedure, UE only receives that SPS PDSCH and DL DAI value are 1 PDCCH in the feedback window, and the sub-frame of uplink that this feedback window is carried out the feedback of ACK/NACK feedback information is that SR reports subframe, and UE will further determine the state of the SR in this subframe so.

(1) if SR is negative in this subframe, then uses ACK/NACK PUCCH resource, report transmission plan in the subframe to carry out the feedback of ACK/NACK feedback information according to non-SR.

(2) if SR is positive in this subframe, then carry out following processing:

At first, UE carries out the space with ACK/NACK feedback information to be feedback and merges, and obtains 2 bits ACK/NACK information to be feedback, and according to default corresponding relation, determines its pairing 2 bits feedback information to be transmitted b(0) and b(1).

Then, UE uses PUCCH format 1b transmission above-mentioned on the SR PUCCH resource of high level configuration b(0) and b(1) pairing modulation symbol d(0).

Wherein, b(0) and b(1) satisfy following mapping relations between value and the merging ACK/NACK information to be feedback:

Situation one, for SPS PDSCH corresponding A CK, the situation of PDCCH with DL DAI=1 corresponding NACK, b(0), b(1)=1,1.

And, its corresponding modulating symbol d(0)=-1.

Result when receiving only SPS PDSCH and corresponding A CK in the technical scheme of being introduced in promptly resulting in such cases result and the background technology is similar, and the modulation symbol constellation of feedback is identical.

Situation two, correspond to NACK for SPS PDSCH, the situation of PDCCH with DL DAI=1 corresponding NACK, b(0), b(1)=0,0.

And, its corresponding modulating symbol d(0)=1.

The result who receives only SPS PDSCH and corresponding NACK in the technical scheme of being introduced in promptly resulting in such cases result and the background technology is similar, and the modulation symbol constellation of feedback is identical.

Other situations, for the distribution situation of other ACK/NACK feedback informations that may exist, in the technical scheme that present embodiment proposed, then do not need particular restriction, but will satisfy uniqueness.

As shown in table 2, the embodiment of the invention provides the information after a kind of concrete ACK/NACK feedback information to be feedback, space merges, and the example of the corresponding relation between the modulation symbol of feedback:

Figure 2011101320342100002DEST_PATH_IMAGE003

Corresponding with the explanation among step S103, step S302 and the step S405, the above-mentioned situation one and the restriction of situation two are in order to solve because UE loses DL DAI value is 1 base station that PDCCH caused and the problem that understands differently and cause between UE.

For example, the base station end has sent SPS PDSCH and DL DAI value in feedback window be 1 PDCCH, but UE has only received SPS PDSCH, and corresponding sub-frame of uplink is that SR reports subframe, and SR is positive, and then UE will feed back on the PUCCH of SR correspondence resource d(0)=1(SPS PDSCH corresponds to NACK) or d(0)=-1(SPS PDSCH corresponds to ACK), wherein, d(0) is the modulation symbol of feedback information correspondence.

The base station still receives according to the mapping relations as table 2 that the embodiment of the invention proposed this moment, and then testing result is:

On SR PUCCH, receive d(0)=1, SPS PDSCH corresponds to NACK, and DL DAI is 1 correctly reception of PDCCH.

On SR PUCCH, receive d(0)=-1, SPS PDSCH corresponds to ACK, and DL DAI is 1 correctly reception of PDCCH.

Above-mentioned testing result is consistent with UE termination receipts situation.

This shows that the above-mentioned situation one and the qualification of situation two have guaranteed the consistency of the understanding of base station side and the corresponding corresponding reception condition of UE side.

Corresponding, in base station side, if the base station has been dispatched the PDCCH of SPS PDSCH and DAI=1 in the window in feedback, and corresponding ACK/NACK feeding back uplink subframe is that SR reports subframe, and then corresponding receiving course is divided into following two kinds of methods.

Input is carried out in method one, base station on SR PUCCH,

(1) if find the no signal transmission, knows that then SR is negative.Input further on ACK/NACK PUCCH, is carried out according to the method for non-SR subframe in the base station, determines the feedback information of the PDCCH correspondence of SPS PDSCH and DAI=1 according to testing result

(2) if find to have the signal transmission, know that then SR is positive.The information among the SR PUCCH is further detected in the base station, and according to as preceding mapping relations, determines the feedback information of the PDCCH correspondence of SPS PDSCH and DAI=1

Input is carried out at ACK/NACK PUCCH in method two, base station,

(1) if find the no signal transmission, then input is further carried out in the base station on SR PUCCH

A, if find the no signal transmission.

I. if the base station determines that UE correctly has been subjected to SPS activation of service signaling, think that then the feedback information of UE this moment is not correctly received, because UE will feed back the ACK/NACK information of SPS PDSCH correspondence at least.
