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
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 corresponding ACK(Acknowledgement of multiple descending sub frames, positive acknowledgement)/NACK(Negative Acknowledgement, Negative Acknowledgement) information, UE completes descending sub frame
n-kon the demodulation, decoding of data after, will be at sub-frame of uplink
nwhether upper data on this descending sub frame of base station feedback need the signaling (being ACK/NACK) retransmitting,
k∈
k, set
kuplink-downlink configuration and the concrete subframe numbering of value and system relevant, as shown in table 1.
Wherein, be corresponding same sub-frame of uplink in " feedback window " described in the application's associated description
kindividual descending sub frame.
In 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, can only the SR within configuration cycle report in subframe and send; Cycle CSI also can only report subframe to send by the CSI within configuration cycle, and its uplink channel resources using is pre-assigned by high level.
LTE-A(Long Term Evolution Advanced, senior Long Term Evolution) in system, base station can configuration UE be used PUCCH(Physical Uplink Control Channel, Physical Uplink Control Channel) format(form) the many bit ACK/NACK feedback informations of 3 transmission.Now, descending Allotment Serial Number DL(Downlink in downlink main carrier to carry in feedback window, descending) DAI(Downlink Assignment Index, descending distribution index) the value PDCCH(Physical Downlink Control Channel that is 1, Physical Downlink Control Channel) in TPC(Transport Power Control, transmitting power control) territory is for load power control signal, and DL DAI value is greater than DL grant(all on 1 PDCCH and subcarrier and permits on downlink main carrier to carry) in TPC territory as ARI(ACK/NACK Resource Indicator, ACK/NACK resource indication), indicate UE to carry out the resource of the PUCCH format 3 that ACK/NACK feedback uses, and in 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), 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) be the modulation symbol that feedback information is corresponding.
If UE has only received SPS PDSCH in feedback window, and SR is that negative(negates), the SPS PUCCH transmitted over resources that UE is being configured by high level
d(0)=1(SPS PDSCH corresponds to NACK) or
d(0)=-1(SPS PDSCH corresponds to ACK), wherein
d(0) be the modulation symbol that feedback information is corresponding.
If UE has only received the PDCCH that DL DAI value is 1 in feedback window, and SR is positive, and UE is in the SR PUCCH transmitted over resources of high level configuration
d(0)=PDCCH that 1(DL DAI value is 1 corresponds to NACK) or
d(0)=-PDCCH that 1(DL DAI value is 1 corresponds to ACK), wherein
d(0) be the modulation symbol that feedback information is corresponding.
If UE has only received the PDCCH that DL DAI value is 1 in feedback window, and SR is negative, the corresponding PUCCH format of the PDCCH 1a/1b transmitted over resources that UE is 1 in DL DAI value
d(0)=PDCCH that 1(DL DAI value is 1 corresponds to NACK) or
d(0)=-PDCCH that 1(DL DAI value is 1 corresponds to ACK), wherein
d(0) be the modulation symbol that feedback information is corresponding.
If UE has received the PDCCH that DL DAI value is greater than 1 in feedback window, UE, in the resource of ARI indication, uses PUCCH format 3 to feed back many bit ACK/NACK and SR information, and wherein ACK/NACK and SR information will be carried out combined coding.
In the process that realizes the embodiment of the present invention, applicant finds that prior art at least exists following problem:
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 the PDCCH that SPS PDSCH and DL DAI value are 1 in feedback window, and in corresponding sub-frame of uplink, send dispatch request simultaneously, now UE cannot 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, determine at present to configure and used PUCCH format 3 transferring ACKs/NACK feedback information, but in feedback window, only receive the PDCCH that SPS PDSCH and DAI value are 1 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 yet definite.
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 present invention has provided the transmission method of the ACK/NACK feedback information of this kind of situation of a kind of correspondence.
As shown in Figure 1, the schematic flow sheet of transmission method of a kind of ACK/NACK feedback information proposing for the embodiment of the present invention, the method specifically comprises the following steps:
Step S101, in the time that terminal equipment receives only the PDCCH that the value of SPS PDSCH that base station sends and DL DAI is 1 in feedback window, terminal equipment judges that the corresponding ACK/NACK feedback information of PDCCH that the value of SPS PDSCH and DL DAI is 1 whether need to be in corresponding sub-frame of uplink reports with together with other UCI.
If judged result is for reporting together, execution step S102;
If judged result reports together for not needing, execution step S104.
In actual operation, based on different application scenarioss, the deterministic process of this step is also divided into multiple concrete situation, in the present embodiment, specifically be specially SR take corresponding sub-frame of uplink and report subframe or CSI to report the situation of subframe as example, corresponding processing procedure is described.
Situation one, in the time that terminal equipment determines that corresponding sub-frame of uplink is specially SR and reports subframe.
Terminal equipment judges the state of SR information.
In the time that terminal equipment judges that SR information is positive state, terminal equipment determines that judged result is to report together, thus execution step S102.
In the time that terminal equipment judges that SR information is negative state, terminal equipment determines that judged result reports together for not needing, thus execution step S104.
Situation two, in the time that terminal equipment determines that corresponding sub-frame of uplink is specially CSI and reports subframe.
Terminal equipment judges the state of CSI information and ACK/NACK information.
In the time that terminal equipment judges that higher level parameters configuration supports that CSI information and ACK/NACK information are transmitted simultaneously, terminal equipment determines that judged result is to report together, thus execution step S102.
In the time that terminal equipment judges that higher level parameters configuration does not support that CSI information and ACK/NACK information are transmitted simultaneously, terminal equipment determines that judged result reports together for not needing, thus execution step S104.
Need to further be pointed out that; it is all concrete examples that the embodiment of the present invention provides for convenience of description that above-mentioned SR reports subframe and CSI to report subframe; for the sub-frame of uplink of other types; also can the thinking based on similar process, the difference of concrete sub-frame of uplink type can't affect protection scope of the present invention.
The corresponding ACK/NACK feedback information of PDCCH that step S102, terminal equipment are 1 to the value of SPS PDSCH and DL DAI carries out space merging, obtains 2 bits ACK/NACK information to be feedback.
Step S103, terminal equipment are in the corresponding Physical Uplink Control Channel PUCCH of other UCI resource, to base-station transmission 2 bit feedback information to be transmitted.
Wherein, 2 bit feedback information to be transmitted and ACK/NACK feedback information to be feedback meet default corresponding relation.
For the convenient explanation of qualifications to above-mentioned, the embodiment of the present invention meets default corresponding relation for the 2 bit feedback information to be transmitted in this step and ACK/NACK feedback information to be feedback and is exemplified below:
(1) in the time that ACK/NACK feedback information to be feedback is specially the corresponding NACK of PDCCH that the value of SPS PDSCH corresponding A CK and DL DAI is 1, corresponding 2 bit feedback information to be transmitted is specially
b(0),
b(1)=1,1, its further corresponding transmitting feedback information, modulation symbol is specially
d(0)=-1.
(2) in the time that ACK/NACK feedback information to be feedback is specially the corresponding NACK of PDCCH that the value of the corresponding NACK of SPS PDSCH and DL DAI is 1, corresponding 2 bit feedback information to be transmitted is specially
b(0),
b(1)=0,0, its further corresponding transmitting feedback information, modulation symbol is specially
d(0)=1.
(3), in the time that ACK/NACK feedback information to be feedback is specially the PDCCH corresponding A CK that the value of SPS PDSCH corresponding A CK and DL DAI is 1, corresponding 2 bit feedback information to be transmitted is specially
b(0),
b(1)=1,0, its further corresponding transmitting feedback information, modulation symbol is specially
d(0)=j.
(4) in the time that ACK/NACK feedback information to be feedback is specially the PDCCH corresponding A CK that the value of the corresponding NACK of SPS PDSCH and DL DAI is 1, corresponding 2 bit feedback information to be transmitted is specially
b(0),
b(1)=0,1, its further corresponding transmitting feedback information, 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 in the situation that not affecting the corresponding effect of content, the variation of the content of concrete corresponding relation can't affect protection scope of the present invention.
Further, in technical scheme proposed by the invention, need to limit as follows:
In the time of the corresponding identical ACK/NACK feedback information of SPS PDSCH, the corresponding NACK of PDCCH that the value of DL DAI is 1, 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 restriction, contrast four kinds of above-mentioned rules of correspondence, can find out, above-mentioned (1) and (2) are the aforesaid situation that needs restriction, because corresponding restriction illustrates and can draw:
In the time that ACK/NACK feedback information to be feedback is specially SPS PDSCH corresponding A CK, if terminal equipment receives only the PDCCH that the value of SPS PDSCH(DL DAI is 1 and takes defeat), corresponding transmitting feedback information situation is identical with (1), and corresponding 2 bit feedback information to be transmitted is specially
b(0),
b(1)=1,1, its further corresponding transmitting feedback information, modulation symbol is specially
d(0)=-1.
In like manner, in the time that ACK/NACK feedback information to be feedback is specially the corresponding NACK of SPS PDSCH, if terminal equipment receives only the PDCCH that the value of SPS PDSCH(DL DAI is 1 and takes defeat), corresponding transmitting feedback information situation is identical with (2), and corresponding 2 bit feedback information to be transmitted is specially
b(0),
b(1)=0,0, its further corresponding transmitting feedback information, modulation symbol is specially
d(0)=1.
This shows, in aforesaid four in corresponding relation, first two corresponding relation (1) and (2) need particular determination, latter two corresponding relation (3) and (4) can exchange or apply other corresponding relation, concrete reason explanation is set forth in follow-up embodiment, is not repeated.
In addition, in actual application scenarios, the operation of this step is specifically as follows:
In the time that terminal equipment determines that corresponding sub-frame of uplink is specially SR and reports subframe, terminal equipment, in the SR PUCCH resource of high level configuration, uses PUCCH format 1b to base-station transmission 2 bit feedback information to be transmitted;
In the time that terminal equipment determines that corresponding sub-frame of uplink is specially CSI and reports subframe, terminal equipment, in the CSI PUCCH resource of high level configuration, uses PUCCH format 2a/2b to base-station transmission 2 bit feedback information to be transmitted.
Certainly; this is the given a kind of concrete operational instances of the embodiment of the present invention; if other forms of resource format can complete corresponding laser propagation effect equally, also can adopt other resource format, such variation does not affect protection scope of the present invention.
Step S104, terminal equipment are in ACK/NACK PUCCH resource, to base-station transmission 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 present invention proposes as shown in Figure 2, specifically comprises the following steps:
The PDCCH that step S201, base station are 1 to the value of terminal equipment scheduling SPS PDSCH and DL DAI in feedback window.
The feedback information that step S202, base station send by PUCCH resource receiving terminal apparatus.
With reference to the explanation in aforesaid step S101, in actual operation, based on different application scenarioss, the receiving course of this step is also divided into multiple concrete situation, in the present embodiment, same to report subframe or CSI to report the situation of subframe as example with SR corresponding in step S101, corresponding processing procedure is described.
Situation one, determine that corresponding sub-frame of uplink is specially SR and reports subframe when terminal equipment, and while adopting corresponding scheme to carry out transmission of feedback information.
In actual application scenarios, the specific implementation of step S202 in such cases can be according to the difference of preferentially carrying out the resource type of input, is divided into following two kinds of methods:
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.
In the time signal being detected, execution step S302;
In the time signal not detected, execution step S303.
Step S302, base station determine that it is positive state that SR reports subframe, and according between the information detecting and ACK/NACK feedback information to be feedback meet default corresponding relation, the corresponding ACK/NACK feedback information of PDCCH that the value of determining SPS PDSCH and DL DAI is 1.
Step S303, base station determine that it is negative state that SR reports subframe, and on ACK/NACK PUCCH, carry out input according to the method for non-SR subframe, the corresponding ACK/NACK feedback information of PDCCH that is 1 according to the value that connects the information measuring and determine SPS PDSCH and DL DAI.
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.
In the time signal being detected, execution step S402;
In the time signal not detected, execution step S403.
Step S402, base station determine that it is negative state that SR reports subframe, and the corresponding ACK/NACK feedback information of PDCCH that is 1 according to the value that connects the information measuring and determine SPS PDSCH and DL DAI.
Input is carried out in step S403, base station on SR PUCCH.
In follow-up processing procedure, base station is according to connecing the corresponding ACK/NACK feedback information of PDCCH that the result measuring determines that the value of SPS PDSCH and DL DAI is 1.
In the time signal being detected, execution step S404;
In the time signal not detected, execution step S406.
Step S404, base station determine that it is positive state that SR reports subframe.
Step S405, base station according to the information detecting and and ACK/NACK feedback information to be feedback between meet default corresponding relation, the corresponding ACK/NACK feedback information of PDCCH that the value of determining SPS PDSCH and DL DAI is 1.
Step S406, base station judge whether terminal equipment correctly receives SPS activation of service signaling.
If base station is determined terminal equipment and is correctly received SPS activation of service signaling, performs step S407;
If base station be can not determine terminal equipment and is correctly received SPS activation of service signaling, performs 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 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 while adopting corresponding scheme to carry out transmission of feedback information.
In such cases, input is carried out in base station in CSI PUCCH resource, and the default corresponding relation being met according to the 2 bit feedback information to be transmitted detecting and ACK/NACK feedback information to be feedback, the corresponding ACK/NACK feedback information of PDCCH that the value of determining SPS PDSCH and DL DAI is 1.
For this kind of situation, the processing procedure in situation one wants simple, can realize with reference to corresponding actual thinking, no longer illustrates in the present embodiment.
Corresponding with the explanation in aforesaid step S103, in the explanation of above-mentioned step S302, step S405 and situation two, between the information detecting of base station institute foundation and ACK/NACK feedback information to be feedback, meet default corresponding relation, corresponding resolution rules specifically comprises:
(1) when transmitting feedback information corresponding to the information detecting is specially
d(0)=-1 o'clock, its corresponding 2 bit 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 corresponding NACK of PDCCH that the value of DL DAI is 1.
(2) when transmitting feedback information corresponding to the information detecting is specially
d(0)=1 o'clock, its corresponding 2 bit feedback information to be transmitted was
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 corresponding NACK of PDCCH that the value of DL DAI is 1.
(3) when transmitting feedback information corresponding to the information detecting is specially
d(0)=when j, its corresponding 2 bit 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 corresponding A CK of PDCCH institute that the value of DL DAI is 1.
(4) when transmitting feedback information corresponding to the information detecting is specially
d(0)=when-j, its corresponding 2 bit 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 corresponding A CK of PDCCH institute that the value of DL DAI is 1.
Similar with the explanation in step S103, first two corresponding relation needs to limit, and latter two corresponding relation can exchange or change.
In actual application scenarios; 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 affect the judgement effect of emphasizing the corresponding relation of restriction in the embodiment of the present invention, such variation does not affect protection scope of the present invention.
Compared with prior art, the technical scheme that the embodiment of the present invention proposes has the following advantages:
By the technical scheme of the application embodiment of the present invention, in feedback window, only receive the situation of the PDCCH that SPS PDSCH and DAI value are 1 for terminal equipment, if terminal equipment need to report in corresponding sub-frame of uplink together with ACK/NACK feedback information and other UCI information, terminal equipment uses corresponding 2 bit of the ACK/NACK feedback information feedback information to be feedback after the corresponding PUCCH resource transmission of other UCI space merges, thereby, use PUCCH format 3 resources to feed back for base station configuration, but terminal equipment has only been received the PDCCH that SPS PDSCH and DL DAI value are 1 in feedback window, to in corresponding sub-frame of uplink, send dispatch request simultaneously, thereby cannot obtain the situation of corresponding PUCCH format 3 resources, corresponding solution has been proposed, guarantee the normal transmission of corresponding ACK/NACK feedback information.
Below, in conjunction with concrete application scenarios, the technical scheme that the embodiment of the present invention is proposed describes.
With reference to aforesaid explanation, specifically report subframe as example explanation the technical program take SR, 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 the PDCCH that SPS PDSCH and DL DAI value are 1 in 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, UE will further determine the state of the SR in this subframe so.
(1) if SR is negative in this subframe, use ACK/NACK PUCCH resource, report transmission plan in subframe to carry out the feedback of ACK/NACK feedback information according to non-SR.
(2) if SR is positive in this subframe, carry out following processing:
First, ACK/NACK feedback information to be feedback is carried out space merging by UE, obtains 2 bits ACK/NACK information to be feedback, and according to default corresponding relation, determine its corresponding 2 bit feedback information to be transmitted
b(0) and
b(1).
Then, UE, in the SR PUCCH resource of high level configuration, uses PUCCH format 1b transmission above-mentioned
b(0) and
b(1) corresponding modulation symbol
d(0).
Wherein,
b(0) and
b(1) between value and merging ACK/NACK information to be feedback, meet following mapping relations:
Situation one, for SPS PDSCH corresponding A CK, the situation of the PDCCH with DL corresponding NACK in DAI=1,
b(0),
b(1)=1,1.
And, its corresponding modulating symbol
d(0)=-1.
The result while receiving only SPS PDSCH and corresponding A CK in the technical scheme of introducing in the result that obtained in such cases and background technology is similar, and the modulation symbol constellation of feedback is identical.
Situation two, correspond to NACK for SPS PDSCH, the situation of the PDCCH with DL corresponding NACK in DAI=1,
b(0),
b(1)=0,0.
And, its corresponding modulating symbol
d(0)=1.
The result that obtained is in such cases similar with the result that receives only SPS PDSCH and corresponding NACK in the technical scheme of introducing in background technology, 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 proposing at the present embodiment, do not need particular restriction, but will meet uniqueness.
As shown in table 2, the information after the embodiment of the present invention provides a kind of concrete ACK/NACK feedback information to be feedback, space and merges, and the example of corresponding relation between the modulation symbol of feedback:
Corresponding with the explanation in step S103, step S302 and step S405, above-mentioned situation one and the restriction of situation two are in order to solve because UE loses the problem that understands differently and cause between base station and the UE that PDCCH that DL DAI value is 1 causes.
For example, base station end has sent the PDCCH that SPS PDSCH and DL DAI value are 1 in feedback window, but UE has only received SPS PDSCH, and corresponding sub-frame of uplink is that SR reports subframe, and SR is positive, and UE will feed back in PUCCH resource corresponding to SR
d(0)=1(SPS PDSCH corresponds to NACK) or
d(0)=-1(SPS PDSCH corresponds to ACK), wherein,
d(0) be the modulation symbol that feedback information is corresponding.

(1) if find no signal transmission, know that SR is negative.Input further, on ACK/NACK PUCCH, is carried out according to the method for non-SR subframe in base station, determines feedback information corresponding to PDCCH of SPS PDSCH and DAI=1 according to testing result
(2) if find that there is signal transmission, know that SR is positive.The information in SR PUCCH is further detected in base station, and according to as front mapping relations, determines feedback information corresponding to PDCCH of SPS PDSCH and DAI=1
Input is carried out at ACK/NACK PUCCH in method two, base station,
(1) if find no signal transmission, input is further carried out in base station on SR PUCCH
If A finds no signal transmission.
If i. base station determines that UE has correctly been subject to SPS activation of service signaling, think that now the feedback information of UE is not correctly received, because UE at least will feed back the ACK/NACK information that SPS PDSCH is corresponding.
If ii. the uncertain UE in base station has correctly been subject to SPS activation of service signaling, can think that now SR is negative, and UE does not receive downlink data transmission; Also can think that now the feedback information of UE is not correctly received
If B finds that there is signal transmission, know that SR is positive.The information in SR PUCCH is further detected in base station, and according to as front mapping relations, determines feedback information corresponding to PDCCH of SPS PDSCH and DAI=1
(2) if find that there is signal transmission, know that SR is negative.Input further, on ACK/NACK PUCCH, is carried out according to the method for non-SR subframe in base station, determines feedback information corresponding to PDCCH of SPS PDSCH and DAI=1 according to testing result.
