Description

ACK/NACK transmission of Information method and apparatus

Technical field

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

Background technology

At LTE(Long Term Evolution, Long Term Evolution) in the Rel-8/9 system, UE(User Equipment, subscriber equipment, be terminal equipment) only be operated on the carrier wave, UE can adopt following several ACK(Acknowledgement, positive acknowledgement)/NACK(Negative Acknowledgement, Negative Acknowledgement) the transmission of feedback information scheme.

Scheme one, PUCCH(Physical Uplink Control Channel, Physical Uplink Control Channel) format 1a scheme.

Modulation system is BPSK(Binary Phase Shift Key, binary phase shift keying) mode, be used to transmit the 1bit(bit) ACK/NACK information.At conventional CP(Cyclic Prefix, Cyclic Prefix) under the scene, 3 row RS(Reference Signal are arranged in each time slot, reference signal), take centre 3 the SC-FDMA(Single Carrier Frequency Division Multiple Access in each time slot, single-carrier frequency division multiple access) symbol transmits, and under expansion CP scene, 2 row RS are arranged in each time slot, take in each time slot the 3rd and the 4th SC-FDMA symbol and transmit, all the other symbols all are used for transmitting feedback information.The modulation symbol of feedback information is except at 1 RB(Resource Block, Resource Block) outside the spread spectrum of the enterprising line frequency of Nei frequency domain resource territory, also need use length on time domain is that 4 orthogonal sequence carries out the time domain spread spectrum, with the users multiplexing quantity in 1 RB of further raising, wherein, the mode of carrying out the time domain spread spectrum is at shortened format(brachymemma form) following time, vacant transmitting SRS (the Sounding Reference Signal that is used for of last symbol, detection reference signal), to use length be that 3 orthogonal sequence carries out the time domain spread spectrum for second time slot.

Scheme two, PUCCH format 1b scheme.

Modulation system is QPSK(Quadrature Phase Shift Key, and quarternary phase-shift keying (QPSK) claims Quadrature Phase Shift Keying again), be used to transmit 2 bit ACK/nack message, channel architecture is consistent with PUCCH format 1a.

Scheme three, PUCCH format 1b with channel selection scheme.

In existing technical scheme, defined ACK/NACK mapping form, be used to represent the state of ACK/ NACK feedback information and the corresponding relation of channel resource and QPSK modulation symbol, as table 1, shown in table 2 and the table 3, be respectively the ACK/NACK mapping form under the scene of different M value, wherein, M represents that the needs of corresponding same sub-frame of uplink carry out the quantity of the descending sub frame of ACK/NACK feedback, for FDD(Frequency Division Duplex, Frequency Division Duplexing (FDD)) system, M fixedly equals 1, for TDD(Time Division Duplex, time division duplex) system, the M value may be different, as shown in table 4 in different uplink-downlink configuration and different sub-frame of uplink.

In this programme, UE is according to ACK/NACK information state and the corresponding ACK/NACK mapping of ACK/NACK number of bits of feedback (being the descending sub frame number M of each sub-frame of uplink correspondence in this programme) inquiry form, select a channel resource at a plurality of PUCCH format 1b channel resources, and determine that 2 send bit b (0) and b (1) (a promptly corresponding QPSK constellation point or modulation symbol).

Shown in table 1, table 2 and table 3, b (0) and the corresponding QPSK modulation symbol of b (1) are sent on the PUCCH format 1b channel resource of selecting; Feedback for the ACK/NACK information of 2,3,4 bits needs 2,3,4 PUCCH format 1b channel resources respectively.

Scheme four, PUCCH format 2 schemes.

This scheme is used for when expansion CP, while transmission cycle CSI(Channel State Information, channel condition information) and ACK/NACK information.

Wherein, ACK/NACK information can be 1 bit or 2 bits, after level is associated in the CSI bit, carries out the combined channel coding transmission with CSI; Modulation system is QPSK; Under conventional CP scene, 2 row RS are arranged in each time slot, take the 2nd and the 6th SC-FDMA symbol transmission in each time slot, and under expansion CP scene, have only 1 row RS in each time slot, take the 4th SC-FDMA symbol transmission in each time slot, all the other symbols all are used for transmitting feedback information.PUCCH format 2 schemes are not carried out the time domain spread spectrum, only carry out the frequency domain spread spectrum in 1 RB, and feedback information obtains 20 coded-bits through after the chnnel coding, obtains 10 symbols through ovennodulation again, respectively two slot transmission.

Scheme five, PUCCH format 2a/2b scheme.

This scheme is used for when conventional CP, while transmission cycle CSI and ACK/NACK information, and channel architecture is consistent with PUCCH format 2, and difference is CSI and ACK/NACK absolute coding/modulation.

Wherein, PUCCH format 2a scheme adopts the BPSK modulation to ACK/NACK information, therefore, only supports 1 bit ACK/nack message transmission; PUCCH format 2b scheme adopts the QPSK modulation to ACK/NACK information, therefore, supports 2 bit ACK/nack message transmission.1 the ACK/NACK symbol that obtains after the modulation will transmit on the secondary series RS that be modulated in each time slot.

In addition, in concrete application scenarios, if also there is SR(Scheduling Request certainly in the current sub-frame of uplink simultaneously, the uplink scheduling request) transmission, so, UE adopts above-mentioned PUCCH format 1a/1b scheme to transmit 1 bit or 2 bit ACK/nack message on the SR channel resource of high level configuration.If cycle of deposit CSI transmission simultaneously and high-rise configuration UE support ACK/NACK and cycle CSI to transmit simultaneously at same sub-frame of uplink in the current sub-frame of uplink, then under conventional CP, adopt PUCCH format 2a/2b, expansion CP adopts down PUCCH format 2 transmission cycle CSI and 1 or 2 bit ACK/nack message simultaneously, if high-rise configuration UE does not support ACK/NACK and cycle CSI to transmit simultaneously at same sub-frame of uplink, then UE abandons cycle CSI information, according to the independent transmission method of above-mentioned ACK/NACK transferring ACK/NACK; If have SR and cycle CSI transmission certainly in the current sub-frame of uplink simultaneously, then UE abandons cycle CSI information, directly transmission ACK/NACK information on the SR channel resource.

For LTE FDD system, UE only needs the ACK/NACK information at a descending sub frame of a sub-frame of uplink feedback.

When single codeword is transmitted: only need the 1 bit ACK/nack message of 1 code word of feedback, adopt PUCCH format 1a transmission plan; If there is SR transmission certainly in the current sub-frame of uplink simultaneously, then UE adopts above-mentioned PUCCH format 1a scheme to transmit 1 bit ACK/nack message on the SR channel resource of high level configuration; Support ACK/NACK and cycle CSI to transmit simultaneously if having cycle CSI transmission and high-rise configuration UE in the current sub-frame of uplink simultaneously at same sub-frame of uplink, then under conventional CP, adopt PUCCH format 2a, expansion CP adopts PUCCH format 2 transmission cycle CSI and 1 bit ACK/nack message simultaneously down, if high-rise configuration UE does not support ACK/NACK and cycle CSI to transmit simultaneously at same sub-frame of uplink, then UE abandons cycle CSI information, adopts format 1a transferring ACK/nack message on the ACK/NACK channel resource; If have cycle CSI transmission in the current sub-frame of uplink simultaneously and affirm SR, UE abandons cycle CSI, adopts format 1a transferring ACK/nack message on the SR channel resource of high level configuration.

When many code words (2 code words) are transmitted: need the 2 bit ACK/nack message of 2 code words of feedback, adopt PUCCH format 1b transmission plan; If there is SR transmission certainly in the current sub-frame of uplink simultaneously, then UE adopts above-mentioned PUCCH format 1b scheme to transmit 2 bit ACK/nack message on the SR channel resource of high level configuration; Support ACK/NACK and cycle CSI to transmit simultaneously if having cycle CSI transmission and high-rise configuration UE in the current sub-frame of uplink simultaneously at same sub-frame of uplink, then under conventional CP, adopt PUCCH format 2b, expansion CP adopts PUCCH format 2 transmission cycle CSI and 2 bit ACK/nack message simultaneously down, if high-rise configuration UE does not support ACK/NACK and cycle CSI to transmit simultaneously at same sub-frame of uplink, then UE abandons cycle CSI information, adopts format 1b transferring ACK/nack message on the ACK/NACK channel resource; If have cycle CSI transmission in the current sub-frame of uplink simultaneously and affirm SR, UE abandons cycle CSI, adopts format 1a/1b transferring ACK/nack message on the SR channel resource of high level configuration.

For LTE TDD system, UE needs to feed back at a sub-frame of uplink ACK/NACK information of a plurality of descending sub frames, and is as shown in table 4.

Wherein, the k value of correspondence in each sub-frame of uplink

Be UE and need carry out the descending sub frame that ACK/NACK feeds back in this sub-frame of uplink, the descending sub frame number of remembering each sub-frame of uplink correspondence is M, and M is to different sub-frame of uplink and different uplink-downlink configuration value differences.

LTE TDD system supports two kinds of ACK/NACK feedback models: multiplexing feedback model (ACK/NACK multiplexing) and merging feedback model (ACK/NACK bundling), wherein, uplink-downlink configuration 5 can only adopt and merge feedback model transferring ACK/nack message.Which kind of feedback model UE adopts dispose by higher level parameters when transferring ACK/nack message.

Below, specify the application process of above two kinds of feedback models:

(1) processing procedure when LTE UE is configured adopt to merge feedback model transferring ACK/nack message.

UE merges (being logic add) with the pairing ACK/NACK information of code word of same position in a plurality of descending sub frames of the same sub-frame of uplink of correspondence, as shown in Figure 1, merges the schematic diagram of transmission for ACK/NACK information of the prior art.

When single codeword is transmitted, obtain 1 bit and merge ACK/NACK information, adopt PUCCH format 1a transmission; When many code words (2 code words) are transmitted, obtain 2 bits and merge ACK/NACK information, adopt PUCCH format 1b transmission.

UE can pass through PDCCH(Physical Downlink Control Channel, Physical Downlink Control Channel) the DAI(Downlink Assignment Index in, descending distribution index) information determines whether to exist loss of data, as shown in Figure 1, DAI represents that current descending sub frame is which subframe that is scheduled in M the descending sub frame; If judgement exists loss of data, UE can send the NACK of merging or does not send the ACK/NACK feedback information; But whether UE can not judge last descending sub frame and lose, therefore, a this scheme regulation UE in the end uplink control channel resource that receives the descending sub frame correspondence of data transmits the ACK/NACK information that merges, to be UE comprise scheduling PDSCH(Physical Downlink Shared Channel according to last PDCCH(that receives in the descending sub frame of data to this channel resource, Physical Downlink Shared Channel) and indication SPS(Semi-persistent scheduling, semi-continuous scheduling) the minimum CCE(Control Channel Element PDCCH of resource release), channel controller) numbering obtains, perhaps when last data that receive is the SPS PDSCH of no corresponding PDCCH, this channel resource is the TPC(Transport Power Control of the PDCCH that activates this SPS PDSCH, through-put power control) a semi-static channel resource of indication.Whether there is transfer of data on the channel resource of descending sub frame correspondence that the base station can be by detecting last scheduling, judges whether UE loses the descending sub frame of last scheduling.

(2) processing procedure when LTE UE is configured to adopt multiplexing feedback model transferring ACK/nack message.

For M〉1 sub-frame of uplink, it (is that the space merges that UE will merge the ACK/NACK information of a plurality of code words (if having disposed many codeword transmission pattern) in should each descending sub frame of sub-frame of uplink, spatial bundling), to judging packet loss according to DAI or not receiving that the descending sub frame of data produces NACK/DTX(Discontinuous Transmission, discontinuous transmission) as feedback information, obtain M bit ACK/nack message, adopt PUCCH format 1b with channel selection scheme to transmit this M bit feedback information, promptly table look-up 1 ~ 3, determine corresponding channel resources and transmitted bit b (0) and b (1), on the channel resource of determining, send b (0) and the pairing QPSK modulation symbol of b (1); As shown in Figure 2, the schematic diagram that transmits for ACK/NACK information multiplexing of the prior art.

For the sub-frame of uplink of M=1, UE does not carry out the space to the ACK/NACK information of many code words and merges, and promptly when single codeword is transmitted, obtains 1 bit ACK/nack message, adopts PUCCH format 1a transmission; When many code words (2 code words) are transmitted, obtain 2 bit ACK/nack message, adopt PUCCH format 1b transmission.

For LTE TDD system, no matter UE has been configured to adopt merging feedback model or multiplexing feedback model transferring ACK/nack message, if there is SR transmission certainly in the current sub-frame of uplink simultaneously, then UE is on the SR channel resource of high level configuration, adopt above-mentioned PUCCH format 1b scheme to transmit 2 bit ACK/nack message b (0) and b (1), tabling look-up 5 obtains, the number of the PDCCH that PDSCH that expression UE correctly receives in a plurality of descending sub frames (as shown in table 4) of the same sub-frame of uplink of correspondence and indication SPS resource discharge; Support ACK/NACK and cycle CSI to transmit simultaneously if having cycle CSI transmission and high-rise configuration UE in the current sub-frame of uplink simultaneously at same sub-frame of uplink, then under conventional CP, adopt PUCCH format 2b scheme, expansion CP adopts PUCCH format 2 schemes transmission cycle CSI and 2 bit ACK/nack message b (0) and b (1) simultaneously down, tabling look-up 5 obtains, the number of the PDCCH that PDSCH that expression UE correctly receives in a plurality of descending sub frames (as shown in table 4) of the same sub-frame of uplink of correspondence and indication SPS resource discharge; If high-rise configuration UE does not support ACK/NACK and cycle CSI to transmit simultaneously at same sub-frame of uplink, then UE abandons cycle CSI information, adopts format 1a/1b or PUCCH format 1b with channel selection transferring ACK/nack message (the as above scheme in the ACK/NACK transmission situation separately) on the ACK/NACK channel resource; If have cycle CSI transmission in the current sub-frame of uplink simultaneously and affirm SR, UE abandons cycle CSI, on the SR channel resource of high level configuration, adopt format 1b to transmit 2 bit ACK/nack message b (0) and b (1), tabling look-up 5 obtains, the number of the PDCCH that PDSCH that expression UE correctly receives in a plurality of descending sub frames (as shown in table 4) of the same sub-frame of uplink of correspondence and indication SPS resource discharge.

In the LTE system, the PUCCH format 1a/1b uplink control channel resource that uses in the above-mentioned transmission plan all is the implicit information channel resource.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 dispatches the minimum CCE numbering of descending control signaling PDCCH or the PDCCH that indication SPS resource discharges of PDSCH by each that sends on this descending carrier, all can calculate and obtain an available uplink control channel resource, claim again " dynamic channel resource ".For the SPS PDSCH that does not have corresponding PDCCH, the channel resource of the ACK/NACK information correspondence of this packet is a semi-static channel resource of the TPC territory indication of the PDCCH of this PDSCH of activation, and this semi-static channel resource is 1 in 4 pre-configured channel resources of high-level signaling.

LTE-A(Long Term Evolution Advanced, senior Long Term Evolution) system determines to support 5 carrier waves to carry out polymerization at most at present, a LTE-A CA (Carrier Aggregation, carrier aggregation) UE need be in the ACK/NACK information of corresponding a plurality of descending carriers of same sub-frame of uplink internal feedback and descending sub frame, and feedback information volume is bigger.Determined PUCCH format 1b with channel selection and PUCCH format 3 multiplexing transmission scheme in the LTE-A system as ACK/NACK information.The maximum transmitted bit number of PUCCH format 1b with channel selection transmission plan is 4 bits, and the maximum transmitted bit number of PUCCH format 3 transmission plans is 20 bits.The concrete employing of high-level signaling configuration LTE-A UE is above-mentioned which kind of multiplexing transmission scheme.

The PUCCH format 1b with channel selection that defines in the LTE-A system is different from the PUCCH format 1b with channel selection transmission plan in the LTE system.This method has been used ACK/NACK mapping form and the channel resource configuration/acquisition methods that is different from the LTE system.ACK/NACK mapping form as table 6 as described in the table 9.In addition, the channel selection in the LTE-A Rel-10 system has also defined pattern a and two kinds of patterns of pattern b.Pattern a does not carry out any union operation, and ACK/NACK information is carried out multiplexing entirely (full multiplexing) feedback; Pattern b need carry out space merging and time domain merging to ACK/NACK information, thereby the feedback information bits number after guaranteeing to merge is no more than 4 bits.Consider in the LTE-A system, the implicit information channel resource reservation of each up-link carrier is all only reserved at the PDCCH on the descending carrier of pairing with it, and PUCCH can only send at up main carrier, only just there is corresponding implicit information channel resource in the PDCCH of the transmission on downlink main carrier to carry, therefore, the required channel resource of PUCCH format 1b with channel selection not necessarily can obtain from the implicit information channel resource, need high-rise configuration or indicate semi-static channel resource by PDCCH, if indicate semi-static channel resource, then can only be that indexed resource just can be reused in the TPC territory of the PDCCH of dispatching downlink subcarrier by PDCCH.

PUCCH Format 3 transmission plans that define in the LTE-A system, the ACK/NACK bit is carried out combined coding, in order to improve the transmitted bit number, 3 of PUCCH format carry out the time domain spread spectrum, adopting length is that 5 orthogonal sequence carries out spread spectrum (to shortened format, it is that 4 orthogonal sequence carries out the time domain spread spectrum that the vacant transmitting SRS that is used for of last symbol, second time slot use length); Adopt the QPSK modulation system, at a PRB(Physical Resource Block, Physical Resource Block) centering can carry 48 coded-bits, 5 users of reusable at most.Channel architecture is: under the conventional CP, each time slot has 2 row RS, takies the 2nd and the 6th SC-FDMA symbol respectively; Under the expansion CP, 1 row RS takies the 4th SC-FDMA symbol in each time slot.The channel resource of PUCCH format 3 is the indicated semi-static channel resource in ACK/NACK resource indication territory (TPC reuses) among the PDCCH of dispatching downlink subcarrier.

In the LTE-A system, for the UE that has disposed a plurality of descending carriers, when UE when descending subcarrier does not receive PDCCH, when UE was configured to use PUCCH format 3 transmission plans, UE can't obtain channel resource, therefore, can't transmit; When UE is configured to use PUCCH format 1b with channel selection transmission plan, when only when downlink main carrier to carry receives data, if still transmit according to Rel-10 channel selection scheme, increased semi-static resource overhead, and when channel selection is pattern b, the merging of ACK/NACK information has been reduced retransmission efficiency.

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

For the UE that has disposed a plurality of descending carriers in the LTE-A system, when UE only received data on downlink main carrier to carry, which kind of ACK/NACK transmission plan UE adopted carry out the ACK/NACK transmission and does not also come to a conclusion.

Based on above reason, the embodiment of the invention has provided a kind of ACK/NACK transmission method that adopts different transmission schemes according to the reception condition of terminal equipment.

In the LTE-A system, for having disposed N(N〉1) terminal equipment of individual descending carrier, only (possible scene is that the base station exists scheduling but loss of data on descending subcarrier when downlink main carrier to carry receives data when this terminal equipment, perhaps descending subcarrier has only been dispatched in the base station), this terminal equipment adopts the ACK/NACK transmission plan of the single carrier UE that defines in the LTE Rel-8/9 system to carry out the ACK/NACK transmission of Information.

As shown in Figure 3, the schematic flow sheet of a kind of ACK/NACK transmission of Information method that proposes for the embodiment of the invention, this method specifically may further comprise the steps:

Step S301, terminal equipment M descending sub frame in N descending carrier receives data.

Wherein, N〉1, M 〉=1, the pairing ACK/NACK information of the data in the described M descending sub frame is transmitted in same sub-frame of uplink.

When described terminal equipment only receives data on downlink main carrier to carry, execution in step S302;

When described terminal equipment is not when only receiving data on downlink main carrier to carry, execution in step S303.

Step S302, described terminal equipment adopt the multiplexing feedback scheme of ACK/NACK in the LTE TDD Rel-8/9 system to carry out the ACK/NACK transmission of Information, perhaps described terminal equipment adopts multiplexing feedback scheme of ACK/NACK or ACK/NACK merging feedback scheme in the LTE TDD Rel-8/9 system to carry out the ACK/NACK transmission of Information according to the ACK/NACK feedback model parameter that defines in the LTE TDD Rel-8/9 system.

In above-mentioned step S302, in fact comprised two kinds of processing modes, specify as follows.

Mode one, described terminal equipment adopt the multiplexing feedback scheme of ACK/NACK in the LTE TDD Rel-8/9 system to carry out the ACK/NACK transmission of Information.

Under the scene of using this kind mode, terminal equipment is when determining only to receive data on downlink main carrier to carry, the multiplexing feedback scheme of ACK/NACK that can directly use in the LTE TDD Rel-8/9 system carries out the ACK/NACK transmission of Information, and need not carry out other processing or Scheme Choice.

Mode two, for the TDD system, described terminal equipment adopts multiplexing feedback scheme of ACK/NACK or ACK/NACK merging feedback scheme in the LTE TDD Rel-8/9 system to carry out the ACK/NACK transmission of Information according to the ACK/NACK feedback model parameter that defines in the LTE TDD Rel-8/9 system.

Under the scene of using this kind mode, terminal equipment is when determining only to receive data on downlink main carrier to carry, at first need to discern predefined ACK/NACK feedback model parameter, wherein, described ACK/NACK feedback model parameter is specially the ACK/NACK feedback model of described terminal equipment under the single carrier configuration that high-level signaling disposes.

Then, according to corresponding recognition result,, select corresponding feedback model to carry out the feedback of ACK/NACK information according to the content that sets in the ACK/NACK feedback model parameter.When the ACK/NACK feedback model of high-level signaling configuration was the multiplexing feedback model of ACK/NACK, described terminal equipment adopted the multiplexing feedback scheme of ACK/NACK in the LTE TDD Rel-8/9 system to carry out the ACK/NACK transmission of Information; When the ACK/NACK feedback model of high-level signaling configuration was ACK/NACK merging feedback model, described terminal equipment adopted the ACK/NACK merging feedback scheme in the LTE TDD Rel-8/9 system to carry out the ACK/NACK transmission of Information.

Wherein, to merge feedback scheme be PUCCH format 1a/1b scheme to the ACK/NACK in the described LTE TDD Rel-8/9 system; As M〉1 the time, the multiplexing feedback scheme of ACK/NACK in the described LTE TDD Rel-8/9 system is a PUCCH format 1b with channel selection scheme; When M=1, the multiplexing feedback scheme of ACK/NACK in the described LTE TDD Rel-8/9 system is a PUCCH format 1a/1b scheme.

Corresponding above-mentioned dual mode, for the technical scheme that the embodiment of the invention proposed is described in detail, below, divide two kinds of scenes to be described as follows to concrete feedback procedure.

Scene one,, described terminal equipment carries out the ACK/NACK transmission of Information when adopting ACK/NACK in the LTE TDD Rel-8/9 system to merge feedback scheme, or described terminal equipment is when adopting the multiplexing feedback scheme of ACK/NACK in the LTE TDD Rel-8/9 system to carry out ACK/NACK transmission of Information and M=1, corresponding ACK/NACK feedback information flow process specifically comprises following flow process.

(1) described terminal equipment carries out logic add to the ACK/NACK information of same numbering code word in the descending sub frame of the M on the downlink main carrier to carry, obtains the ACK/NACK information that 1 or 2 bits merge.

(2) described terminal equipment is determined corresponding channel resources, concrete adopts a kind of in following several modes.

Mode A, described terminal equipment number according to last minimum CCE that receives the PDCCH in the descending sub frame of data in M the descending sub frame on downlink main carrier to carry, determine 1 PUCCH format 1a/1b channel resource.

Wherein, described PDCCH comprises the PDCCH that scheduling PDSCH transmission or indication SPS resource discharge.

Mode B, when last receives the data that receive in the descending sub frame of data for the SPS PDSCH of no corresponding PDCCH in the M of described terminal equipment on the downlink main carrier to carry descending sub frame, described terminal equipment is determined 1 PUCCH format 1a/1b channel resource according to the TPC indication territory of the PDCCH that activates described SPS PDSCH.

Wherein, the channel resource of described TPC indication territory indication is in the pre-configured a plurality of semi-static channel resource of high-level signaling one.

(3) described terminal equipment adopts PUCCH format 1a/1b scheme to transmit the ACK/NACK information of described merging on the described PUCCH format 1a/1b channel resource of determining.

Scene two, when described terminal equipment adopts the multiplexing feedback scheme of ACK/NACK in the LTE TDD Rel-8/9 system to carry out the ACK/NACK transmission of Information, corresponding ACK/NACK feedback information flow process specifically comprises following flow process.

(1) described terminal equipment carries out logic add to the ACK/NACK information of a plurality of code words in the same descending sub frame of the descending sub frame of the M on the downlink main carrier to carry, produce NACK/DTX as feedback information to not receiving the descending sub frame that data or judgment data lose, obtain M bit ACK/nack message.

(2) described terminal equipment is determined the respective alternative channel resource, concrete adopts a kind of in following several modes.

Mode A, described terminal equipment are numbered according to the minimum CCE of the PDCCH that receives in each descending sub frame in M the descending sub frame on downlink main carrier to carry, are determined to many M PUCCH format 1b channel resources, as alternative channel resource.

Mode B, when data that receive at least one descending sub frame in the M of described terminal equipment on the downlink main carrier to carry descending sub frame during for the SPS PDSCH of no corresponding PDCCH, described terminal equipment is according to the TPC indication territory of the PDCCH that activates described SPS PDSCH, determine 1 PUCCH format 1b channel resource, as the alternative channel resource of described descending sub frame correspondence.

(3) described terminal equipment adopts PUCCH format 1b with channel selection scheme, according to described M bit ACK/nack message, in described M at the most the alternative channel resource of determining of PUCCH format 1b, select a channel resource, and determine a qam constellation point.

(4) described terminal equipment sends described definite qam constellation point on the described channel resource of selecting.

Need to prove, in the multiplexing feedback scheme of above-mentioned ACK/NACK, UE is according to described M bit ACK/nack message, in described M at the most the alternative channel resource of determining of PUCCH format 1b, select a channel resource, and determine that the ACK/NACK mapping form that uses in the qam constellation point process can be the ACK/NACK mapping form that defines in the LTE Rel-8/9 system, referring to aforesaid table 1 to table 3, also can be for the ACK/NACK mapping form under a plurality of descending carrier configurations that define in the LTE-A TDD system, referring to aforementioned table 9.

In the application process of reality; which kind of above-mentioned mode of concrete application; and concrete employ mode is carried out determining of channel resource or alternative channel resource in corresponding scene, and can adjust according to actual needs, such variation does not influence protection scope of the present invention.

Step S303, described terminal equipment adopt the ACK/NACK multiplexing transmission scheme under a plurality of descending carriers configurations in the pre-configured LTE-A system of high-level signaling to carry out the ACK/NACK transmission of Information.

Wherein, the ACK/NACK multiplexing transmission scheme under a plurality of descending carriers configurations in the pre-configured LTE-A system of described high-level signaling is specially:

PUCCH format 3 schemes or PUCCH format 1b with channel selection scheme.

Wherein, the channel resource in PUCCH format 3 schemes is in pre-configured a plurality of semi-static PUCCH format 3 channel resources of the high-level signaling of the ACK/NACK resource indication territory indication among the PDCCH of dispatching downlink subcarrier one.

In actual applications, described PUCCH format 1b with channel selection scheme adopts ACK/NACK mapping form and the resources employment methods under a plurality of descending carrier configurations that define in the LTE-A system (promptly to be different from the ACK/NACK mapping form in the LTE Rel-8/9 system, table 1 is to table 3), the content of concrete ACK/NACK mapping form referring to aforesaid table 6 to table 9, the channel resource of M at the most wherein be high-level signaling pre-configured/one group of semi-static channel resource of PDCCH indication, the perhaps combination of dynamic channel resource of determining for minimum CCE and the high-level signaling configuration/PDCCH semi-static channel resource of indicating according to the PDCCH that on downlink main carrier to carry, transmits.

Need further be pointed out that, above-mentioned corresponding processing policy is mainly used in the TDD system, and in the FDD system, if described terminal equipment only receives data on downlink main carrier to carry, so, described terminal equipment directly adopts PUCCH format 1a/1b scheme to carry out the ACK/NACK transmission of Information, promptly with the multiplexing feedback scheme during M=1 in the above-mentioned TDD system.

Need further be pointed out that, in the above-mentioned processing procedure, do not get rid of and when UE only receives data on downlink main carrier to carry, adopt other transmission plans, for example PUCCH format 3 transmission plans (if PUCCH format 3 transmission plans also can be applicable to single carrier UE) or other new ACK/NACK transmission plans.

Corresponding, in base station side, the above-mentioned identical rule of base station applies is carried out the ACK/NACK transmission of Information, be that the foundation selected of concrete mode becomes described base station and whether only on downlink main carrier to carry described terminal equipment carried out transfer of data, 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.

At first, the processing procedure on the UE is described as follows.

When the LTE-A UE that has been configured a plurality of descending carriers only when downlink main carrier to carry receives data, according to the difference of system type, be divided into following two kinds of application scenarioss.

Application scenarios one, FDD system.

UE is according to the reception data on the downlink main carrier to carry, each code word is generated 1 bit ACK/NACK feedback information, obtain 1 bit (to single codeword transmission) or 2 bits (to many codeword transmission) ACK/NACK feedback information, adopt PUCCH format 1a(single codeword) or the many code words of PUCCH format 1b() transmission plan transmits on PUCCH format 1a/1b channel resource.

Wherein, to be UE comprise the PDCCH that scheduling PDSCH and indication SPS resource discharge according to the PDCCH(that receives to described PUCCH format 1a/1b channel resource) minimum CCE numbering obtain, perhaps when the data that receive were the SPS PDSCH of no corresponding PDCCH, this channel resource was a semi-static channel resource of the TPC indication of the PDCCH of this SPS PDSCH of activation.

If there is SR transmission certainly in the current sub-frame of uplink simultaneously, to having disposed the UE of a plurality of descending carriers:

When definition ACK/NACK adopts PUCCH format 3 transmission plans in the LTE-A system, pass through 1 bit SR and ACK/NACK combined coding in the LTE-A system, adopt PUCCH format 3 schemes on PUCCH format 3 channel resources, to transmit SR and ACK/NACK simultaneously, but because PUCCH format 3 channel resources are by the indication territory of the ACK/NACK resource among the PDCCH of dispatching downlink subcarrier (reusing the TPC territory) indication, and when UE only receives data on downlink main carrier to carry, can't obtain PUCCH format 3 channel resources, therefore, when UE only when downlink main carrier to carry receives data, but the UE rollback is the single carrier operation pattern, adopt SR and ACK/NACK while transmission plan in the LTE Rel-8/9 system, promptly on the SR channel resource, adopt above-mentioned PUCCH format 1a/1b scheme to transmit 1 or the 2 bit ACK/NACK feedback information of described generation; The base station can determine which kind of send mode UE adopts by in PUCCH format 3 and the enterprising line data blind check of PUCCH format 1a/1b channel resource.

When definition ACK/NACK in the LTE-A system adopts PUCCH format 1b with channel selection transmission plan, in the LTE-A system by the ACK/NACK information of many code words of each descending carrier being carried out logic add (being that the space merges), obtain the ACK/NACK information that 2 bits merge, on the channel resource of SR, adopt PUCCH format 1b scheme to transmit the ACK/NACK information that 2 bits merge, at this moment, when UE only receives data on downlink main carrier to carry, can not rollback be the single carrier operation pattern, can not adopt SR and ACK/NACK while transmission plan in the LTE Rel-8/9 system, this is because SR and the ACK/NACK while transmission plan in the LTE Rel-8/9 system also need transmit 1 or 2 bit ACK/nack message on the SR channel resource, when base station scheduling descending subcarrier, but when UE loses all data on descending subcarrier, if UE is according to SR in the LTE Rel-8/9 system and ACK/NACK transmission plan transmission simultaneously, then 2 bit ACK/nack message of sending on the SR channel resource of UE is represented the independently ACK/NACK information of 2 code words that UE receives on PCC, and the base station will be interpreted as the ACK/NACK information that the many code word space on each carrier wave merge at 2 bit ACK that receive on the SR channel resource/nack message, with causing base station and UE that understanding differently of ACK/NACK information caused, influence retransmission efficiency.Possible solution: method 1: to two SR channel resources of same UE configuration, the SR channel resource of a corresponding LTE Rel-8/9 system, SR channel resource under a corresponding LTE-A multicarrier disposes, then two resources are independent, when UE only receives data on downlink main carrier to carry, but rollback is the single carrier operation pattern, adopt SR and ACK/NACK while transmission plan in the LTE Rel-8/9 system, promptly on the SR channel resource of LTE Rel-8/9 system correspondence, adopt above-mentioned PUCCH format 1a/1b scheme to transmit 1 or the 2 bit ACK/NACK feedback information of described generation; The base station can determine which kind of send mode UE adopts by SR channel resource and the corresponding enterprising line data blind check of SR channel resource of LTE-A multicarrier configuration in LTE Rel-8/9 system correspondence.Method 2: no matter whether UE only receives data at downlink main carrier to carry, always transmit according to SR under the LTE-A multicarrier system and ACK/NACK while transmission plan, the ACK/NACK information that promptly always obtains the merging of 2 bits is transmitted on the SR channel resource, produces NACK as the ACK/NACK information that merges for the descending carrier of not receiving data; The base station only needs to carry out Data Detection according to format 1b on the SR channel resource and gets final product.

Support ACK/NACK and cycle CSI to transmit simultaneously if having cycle CSI feedback and high-rise configuration UE in the current sub-frame of uplink simultaneously at same sub-frame of uplink, then UE is on PUCCH format 2/2a/2b channel resource, conventional CP adopts PUCCH format 2a(that single codeword is transmitted down) or PUCCH format 2b(to many codeword transmission), the secondary series RS that ACK/NACK information is modulated at each time slot transmits, expansion CP adopts PUCCH format 2 down, 1(single codeword with described generation) or the many code words of 2() after bit ACK/NACK feedback information level is associated in CSI information, carry out the combined coding transmission; If high-rise configuration UE does not support ACK/NACK and cycle CSI to transmit simultaneously at same sub-frame of uplink, then UE abandons cycle CSI information, adopts format 1a/1b only to transmit 1 or 2 bit ACK/nack message according to the independent transmission method of above-mentioned ACK/NACK.

If have cycle CSI feedback in the current sub-frame of uplink simultaneously and affirm SR, UE abandons cycle CSI, adopts format 1a/1b scheme to transmit 1 or the 2 bit ACK/NACK feedback information of described generation on the SR channel resource.SR channel resource and PUCCH format 2/2a/2b channel resource are the pre-configured semi-static channel resource of high-level signaling.

Application scenarios two, TDD system.As previously mentioned, should specify as follows with comprising two kinds of processing methods under the scene.

Method 1: the ACK/NACK feedback model of the single carrier UE that defines in the LTE TDD Rel-8/9 system according to the higher level parameters configuration transmits.

(1) merge feedback model if the feedback model that UE is configured is ACK/NACK, then corresponding the processing comprises:

UE merges (logic add) to the ACK/NACK feedback information of same numbering code word in the descending sub frame of M on the downlink main carrier to carry, obtain 1 bit (to the single codeword transmission) or 2 bits (to many codeword transmission) and merge ACK/NACK information, as shown in Figure 1, adopt PUCCH format 1a(single codeword)/the many code words of 1b() transmission plan transmits on PUCCH format 1a/1b channel resource.

UE can judge whether to exist data-bag lost according to the DAI value among the PDCCH, and DAI represents that current descending sub frame is the subframe which is scheduled in M the descending sub frame, as shown in Figure 1, can judge that by DAI=1 and DAI=3 second descending sub frame lose; If the UE judgement exists loss of data, UE can send the NACK of merging or does not send the ACK/NACK feedback information.

Described PUCCH format 1a/1b channel resource UE comprises the PDCCH that scheduling PDSCH and indication SPS resource discharge according to last PDCCH(that receives in the descending sub frame of data in the descending sub frame of M on the downlink main carrier to carry) minimum CCE numbering obtain, perhaps when last data that receive during for the SPS PDSCH of no corresponding PDCCH, in the pre-configured a plurality of semi-static channel resource of the high-level signaling that this channel resource is indicated for the TPC of the PDCCH that activates this SPS PDSCH one; Whether there is transfer of data on the channel resource of descending sub frame correspondence that the base station can be by detecting last scheduling, judges whether UE loses the descending sub frame of last scheduling.

(2) if the feedback model that UE is configured is the multiplexing feedback model of ACK/NACK, then corresponding processing procedure comprises:

As M〉1 the time, it (is that the space merges that UE carries out logic add to the ACK/NACK feedback information of a plurality of code words in the same descending sub frame of the descending sub frame of M on the downlink main carrier to carry (if having disposed many codeword transmission pattern), spatial bundling), as shown in Figure 2, produce NACK/DTX as feedback information to not receiving the descending sub frame that data or judgment data lose, obtain M bit ACK/NACK feedback information, adopt PUCCH format 1b with channel selection transmission plan, according to table 1 to the ACK/NACK shown in the table 3 mapping form, the perhaps mapping form shown in the table 9, in candidate's M at the most PUCCH format 1b channel resource, select a channel resource and corresponding 2 bit b (0) and b (1), on the channel resource of selecting, send described 2 bit informations.

Wherein, to be UE comprise the PDCCH that scheduling PDSCH and indication SPS resource discharge according to each PDCCH(that receives in the descending sub frame of data in M the descending sub frame for described M at the most PUCCH format 1b channel resource) minimum CCE numbering obtain, perhaps when data that receive in the capable subframe during for the SPS PDSCH of no corresponding PDCCH, in the pre-configured a plurality of semi-static channel resource of the high-level signaling that the channel resource of this descending sub frame correspondence is indicated for the TPC of the PDCCH that activates this SPS PDSCH one.

When M=1, has only a descending sub frame, UE does not carry out the space merging to the ACK/NACK feedback information of many code words, according to the Data Receiving on the downlink main carrier to carry, directly each code word is produced 1 bit ACK/NACK feedback information, obtain 1 bit (to single codeword transmission) or 2 bits (to many codeword transmission) ACK/NACK feedback information, adopt PUCCH format 1a(single codeword)/the many code words of 1b() transmission plan transmits on PUCCH format 1a/1b channel resource.

Wherein, to be UE comprise the PDCCH that scheduling PDSCH and indication SPS resource discharge according to the PDCCH(in this descending sub frame on the downlink main carrier to carry to described PUCCH format 1a/1b channel resource) minimum CCE numbering obtain, perhaps when data that receive during for the SPS PDSCH of no corresponding PDCCH, in the pre-configured a plurality of semi-static channel resource of the high-level signaling that this channel resource is indicated for the TPC of the PDCCH that activates this SPS PDSCH one.

Method 2: always carry out the ACK/NACK transmission according to multiplexing feedback model, it is the ACK/NACK feedback model parameter that UE does not need further to judge the single carrier UE that defines in the LTE TDD Rel-8/9 system of high-rise configuration, directly according to multiplexing feedback scheme transferring ACK/nack message, the description of the same multiplexing feedback model of transmission plan in detail.

Under above-mentioned two kinds of methods, no matter UE has been configured to adopt merging feedback model or multiplexing feedback model transferring ACK/nack message,

If there is SR transmission certainly in the current sub-frame of uplink simultaneously, then UE is on the SR channel resource, adopt above-mentioned PUCCH format 1b scheme to transmit 2 bit ACK/nack message b (0) and b (1), wherein, the number of the PDCCH that PDSCH that correctly receives in a described b (0) and the M of b (1) expression UE on the downlink main carrier to carry descending sub frame and indication SPS resource discharge, as shown in table 5;

Support ACK/NACK and cycle CSI to transmit simultaneously if having cycle CSI feedback and high-rise configuration UE in the current sub-frame of uplink simultaneously at same sub-frame of uplink, then UE adopts PUCCH format 2b scheme under conventional CP, the secondary series RS that 2 bit ACK/nack message b (0) and b (1) is modulated at each time slot transmits, UE adopts PUCCH format 2 schemes under the expansion CP, after 2 bit ACK/nack message b (0) and b (1) level is associated in CSI information, carry out the combined coding transmission, wherein, the number of the PDCCH that PDSCH that correctly receives in a described b (0) and the M of b (1) expression UE on the downlink main carrier to carry descending sub frame and indication SPS resource discharge, as shown in table 5; If high-rise configuration UE does not support ACK/NACK and cycle CSI to transmit simultaneously at same sub-frame of uplink, then UE abandons cycle CSI information, adopts above-mentioned method transferring ACK/nack message that has the ACK/NACK transmission on the ACK/NACK channel resource;

If have cycle CSI feedback in the current sub-frame of uplink simultaneously and affirm SR, UE abandons cycle CSI, on the SR channel resource, adopt format 1b scheme to transmit 2 bit ACK/nack message b (0) and b (1), wherein the number of the PDCCH of PDSCH that correctly receives in the M of b (0) and b (1) expression UE on the downlink main carrier to carry descending sub frame and the release of indication SPS resource is as shown in table 5.

Above-mentioned SR channel resource and PUCCH format 2/2a/2b channel resource are the pre-configured semi-static channel resource of high-level signaling.

Correspondingly, if UE receives data at descending subcarrier, then UE comprises PUCCH format 3 or PUCCH format 1b with channel selection transmission plan according to the ACK/NACK multiplexing transmission scheme transferring ACK/NACK under the multicarrier configuration in the LTE-A system of high level configuration.

When UE was configured to adopt PUCCH format 3 transferring ACKs/NACK: UE was according to the transmission mode of descending carrier number and each descending carrier of configuration, and the descending sub frame that the needs of a sub-frame of uplink correspondence carry out ACK/NACK feedback is counted M(to FDD, M=1), determine the ACK/NACK bit number that UE need feed back, when number of bits of feedback during greater than 20 bits, ACK/NACK feedback information to the many code words in the same descending sub frame carries out logic add (being that the space merges), on PUCCH format 3 channel resources, adopt PUCCH format 3 schemes to send the ACK/NACK feedback bits that obtains.

When UE was configured to adopt PUCCH format 1b with channel selection transferring ACK/NACK: UE was according to the transmission mode of descending carrier number and each descending carrier of configuration, and the descending sub frame that the needs of a sub-frame of uplink correspondence carry out ACK/NACK feedback is counted M(to FDD, M=1), determine the ACK/NACK bit number of UE feedback, and then definite UE adopts mode a or mode b transmission, when number of bits of feedback is no more than 4bit, adopt mode a, promptly the ACK/NACK feedback information is not carried out any closing, when number of bits of feedback surpasses 4 bits, adopt mode b, need carry out the space to the ACK/NACK feedback bits merges, or the merging of space merging+time domain, obtain M bit ACK/NACK feedback information; UE is according to the ACK/NACK mapping form under the multicarrier configuration in the LTE-A system, promptly table 6 is to table 9, on M candidate's at the most PUCCH format 1b channel resource, select a channel resource, with a QPSK constellation point (2 bit b (0) and b (1)), on the PUCCH format 1b channel resource of selecting, send 2 bit b (0) and b (1) according to PUCCH format 1b scheme.

Wherein, in pre-configured a plurality of semi-static PUCCH format 3 channel resources of the high-level signaling of ACK/NACK resource indication territory (TPC reuses in the territory) indication among the above-mentioned PUCCH format 3 channel resources PDCCH that is the dispatching downlink subcarrier; Above-mentioned PUCCH format 1b with channel selection adopts the ACK/NACK mapping form under the multicarrier configuration in the LTE-A system, one group of semi-static channel resource of pre-configured/PDCCH indication that M channel resource is high-level signaling at the most, the perhaps combination of dynamic channel resource of determining for minimum CCE and the high-level signaling configuration/PDCCH semi-static channel resource of indicating according to the PDCCH that on downlink main carrier to carry, transmits.

On the other hand, the respective handling procedure declaration to the base station is as follows.

When the base station only when downlink main carrier to carry has been dispatched data, according to the difference of system type, be divided into following two kinds of application scenarioss.

Application scenarios one, FDD system.

According to the transmission mode of downlink main carrier to carry, on corresponding PUCCH format 1a/1b channel resource, transmit according to PUCCH format 1a(single codeword) or the many codeword transmission of PUCCH format 1b() transmission plan reception ACK/NACK information; The same UE of the mode of PUCCH channel resource is determined in the base station, the PDCCH that promptly comprises scheduling PDSCH and the release of indication SPS resource) minimum CCE numbering acquisition according to the PDCCH(of base station transmission, when perhaps the data that send when the base station were the SPS PDSCH of no corresponding PDCCH, this channel resource was a semi-static channel resource of the TPC indication of the PDCCH of this SPS PDSCH of activation; The base station repeat feedback information is the code word of NACK; If the base station does not detect data on above-mentioned channel resource, then the base station judges that UE loses the descending sub frame of dispatching on the downlink main carrier to carry, retransmits this subframe.

If current sub-frame of uplink is a cycle SR subframe, be divided into following two kinds of situations:

Situation 1: when UE is configured to adopt PUCCH format 3 transferring ACKs/NACK, but the UE rollback is the single carrier operation pattern, both adopted SR in the LTE Rel-8/9 system and ACK/NACK transmission plan simultaneously, this moment, the base station needed to adopt the transmission of PUCCH format 1a(single codeword on the SR resource of high level configuration) or the many codeword transmission of PUCCH format 1b() transmission plan and base station by the PDCCH of dispatching downlink subcarrier in the ARI territory adopt PUCCH format 3 transmission plan blind check ACK/NACK information on disposing to PUCCH format 3 channel resources of UE; If ACK/NACK information is determined in the SR transmitted over resources in the base station, then the base station determines that there is sure SR simultaneously in UE, promptly has dispatch request, 1 or 2 bit ACK/NACK represent the ACK/NACK information of each code word of downlink main carrier to carry, the base station retransmits the code word of NACK correspondence; If the base station determines that ACK/NACK information is in PUCCH format 3 transmitted over resources, then the base station determines that there is not dispatch request in UE, the independently ACK/NACK information of each code word or carried out the ACK/NACK information that many code word space merge on each downlink main carrier to carry of ACK/NACK information representation, the base station repeat feedback information is code word/subframe of NACK; Perhaps, the base station also can be detected the SR resource earlier, if there is the ACK/NACK transmission in judgement, does not then need further to detect PUCCH format 3 channel resources; Otherwise, further detect PUCCH format 3 channel resources again; If the base station does not all detect ACK/NACK information on above-mentioned channel resource, then the base station judges that there is not dispatch request in UE, and loses the descending sub frame of dispatching on the downlink main carrier to carry, retransmits this subframe.

Situation 2: when UE is configured to adopt PUCCH format 1b with channel selection scheme transferring ACK/NACK, UE can not rollback be the single carrier operation pattern, can not adopt SR and ACK/NACK while transmission plan in the LTE Rel-8/9 system, reason sees the UE end for details to be described, do not give unnecessary details at this, corresponding with the behavior of UE end:

When UE employing method 1 was transmitted SR and ACK/NACK information simultaneously: this moment, high level disposed two SR channel resources, the SR channel resource of the corresponding LTE Rel-8/9 of a resource system, SR channel resource under the corresponding LTE-A multicarrier of resource disposes, two resources are independent, the base station needs on above-mentioned 2 SR resources and on the corresponding PUCCH format 1a/1b channel resource, according to the transmission of PUCCH format 1a(single codeword) or the many codeword transmission of PUCCH format 1b() transmission plan blind check ACK/NACK information; If the SR transmitted over resources of ACK/NACK information in LTE Rel-8/9 system correspondence determined in the base station, then the base station determines that there is sure SR simultaneously in UE, promptly there is dispatch request, and only receive data at downlink main carrier to carry, the 1(single codeword transmission that obtains) or the many codeword transmission of 2() bit ACK/nack message represents the ACK/NACK feedback information of each code word on the downlink main carrier to carry, repeat feedback information is the code word of NACK; If the base station determines that ACK/NACK information is in the corresponding SR transmitted over resources of LTE-A multicarrier configuration, then the base station determines that there is sure SR simultaneously in UE, promptly there is dispatch request, and only data have been received at downlink main carrier to carry, 2 bit ACK/NACK represents the merging of the ACK/NACK information of many code words on each descending carrier, the code word on the descending carrier of base station re-transmission NACK correspondence; If the base station determines that ACK/NACK information is in PUCCH format 1a/1b transmitted over resources, then the base station determines that there is not dispatch request in UE, 1 or 2 bit ACK/nack message represent the independently ACK/NACK information of each code word on the downlink main carrier to carry, the base station repeat feedback information is the code word of NACK; Perhaps, the base station also can be detected the SR resource earlier, if there is the ACK/NACK transmission in judgement, does not then need further to detect PUCCH format 1a/1b channel resource; Otherwise, further detect PUCCH format 1a/1b channel resource again; If the base station does not all detect ACK/NACK information on above-mentioned channel resource, then the base station judges that there is not dispatch request in UE, and loses the descending sub frame of dispatching on the downlink main carrier to carry, retransmits this subframe;

When UE employing method 2, no matter whether UE only receives data at downlink main carrier to carry, always transmit according to SR under the LTE-A multicarrier system and ACK/NACK while transmission plan, then the base station only needs on the SR resource of high level configuration and on the corresponding PUCCH format 1a/1b channel resource, according to the transmission of PUCCH format 1a(single codeword) or the many codeword transmission of PUCCH format 1b() transmission plan blind check ACK/NACK information; If the base station determines that ACK/NACK information is in the SR transmitted over resources, then the base station determines that there is sure SR simultaneously in UE, promptly have dispatch request, 2 bit ACK/NACK represents the merging of the ACK/NACK information of many code words on each descending carrier, the code word on the descending carrier of base station re-transmission NACK correspondence; If the base station determines that ACK/NACK information is in PUCCH format 1a/1b transmitted over resources, then the base station determines that there is not dispatch request in UE, 1(single codeword transmission) or the many codeword transmission of 2() bit ACK/nack message represents the independently ACK/NACK information of each code word on the downlink main carrier to carry, the base station repeat feedback information is the code word of NACK; Perhaps, the base station also can be detected the SR resource earlier, if there is the ACK/NACK transmission in judgement, does not then need further to detect PUCCH format 1a/1b channel resource; Otherwise, further detect PUCCH format 1a/1b channel resource again; If the base station does not all detect ACK/NACK information on above-mentioned channel resource, then the base station judges that there is not dispatch request in UE, and loses the descending sub frame of dispatching on the downlink main carrier to carry, retransmits this subframe.

If have cycle CSI feedback in the current sub-frame of uplink simultaneously, be divided into following two kinds of situations:

Situation 1: if high-rise configuration UE supports ACK/NACK and cycle CSI to transmit simultaneously at same sub-frame of uplink, under conventional CP, the base station according to the transmission mode of downlink main carrier to carry directly on the PUCCH format 2/2a/2b resource of high level configuration according to the conventional CP of PUCCH format 2a(, 1 bit ACK/NACK feedback information, corresponding single codeword is transmitted) or the conventional CP of PUCCH format 2b(, 2 bit ACK/NACK feedback information, corresponding many codeword transmission) or PUCCH format 2(expansion CP) transmission plan receives ACK/NACK, 1(single codeword transmission) or the many codeword transmission of 2() bit ACK/nack message represents the independently ACK/NACK information of each code word on the downlink main carrier to carry, the base station repeat feedback information is the code word of NACK; If the base station does not detect ACK/NACK information on above-mentioned PUCCH format 2/2a/2b channel resource, then the base station judges that UE loses the descending sub frame of dispatching on the downlink main carrier to carry, retransmits this subframe.

Situation 2: if high-rise configuration UE does not support ACK/NACK and cycle CSI to transmit simultaneously at same sub-frame of uplink, then the base station judges that UE abandons cycle CSI information, only the situation according to above-mentioned transferring ACK/nack message receives ACK/NACK, in the transmission of PUCCH format 1a(single codeword)/the many codeword transmission of 1b() adopt format 1a/1b scheme to detect ACK/NACK information on the channel resource; If the base station does not detect ACK/NACK information on above-mentioned PUCCH format 1a/1b channel resource, then the base station judges that UE loses the descending sub frame of dispatching on the downlink main carrier to carry, retransmits this subframe.

If current sub-frame of uplink is a cycle SR subframe, and be cycle CSI feedback subframe simultaneously, the base station determines that UE does not transmit the CSI feedback, carries out ACK/NACK according to above-mentioned SR subframe situation and receives.

Application scenarios two, TDD system.Corresponding with the processing of UE side, should specify as follows with comprising two kinds of processing methods under the scene equally.

Method 1: corresponding with the method 1 that UE is adopted, reception programme is determined according to the ACK/NACK transmission mode that UE is configured in the base station.

(1) when definite UE is configured to merge feedback model, the corresponding processing comprises:

Situation 2: if high-rise configuration UE does not support ACK/NACK and cycle CSI to transmit simultaneously at same sub-frame of uplink, then the base station judges that UE abandons cycle CSI information, only the situation according to above-mentioned transferring ACK/nack message receives ACK/NACK, promptly on PUCCH format 1a/1b channel resource, adopt the transmission of format 1a(single codeword) or the many codeword transmission of PUCCH format 1b() scheme detection ACK/NACK information, 1 bit (single codeword transmission) or 2 bits (many codeword transmission) ACK/NACK feedback information are represented the ACK/NACK pooling information of same numbering code word in a plurality of descending sub frames on the downlink main carrier to carry, and the base station retransmits all code words of the numbering of corresponding NACK in M the subframe; If the base station does not detect ACK/NACK information on above-mentioned PUCCH format 1a/1b channel resource, then the base station judges that UE loses all descending sub frames of dispatching on the downlink main carrier to carry, retransmits the subframe of all scheduling on the downlink main carrier to carry.

(2) when definite UE is configured to multiplexing feedback model, the corresponding processing comprises:

As M〉1 the time, the base station is on M candidate PUCCH format 1b channel resource at the most, receive ACK/NACK according to PUCCH format 1b with channel selection transmission plan, and (or the ACK/NACK shown in the table 9 shines upon form to shine upon form according to table 1 to the ACK/NACK shown in the table 3, consistent the getting final product of form with the UE employing) determine M bit ACK/NACK feedback information, the feedback information of each descending sub frame of dispatching on the corresponding respectively downlink main carrier to carry is that the subframe of NACK/DTX retransmits to feedback information; M PUCCH format 1b channel resource is the minimum CCE acquisition of base station according to the PDCCH in the descending sub frame of each scheduling in M the descending sub frame at the most, or when the data of a descending sub frame were the SPS PDSCH of no corresponding PDCCH, this channel resource was a semi-static channel resource of the TPC indication of the PDCCH of this SPS PDSCH of activation; If the base station is not all detecting ACK/NACK information on M channel resource at the most, then the base station judges that UE loses all descending sub frames of dispatching on the downlink main carrier to carry, retransmits all subframes of dispatching on the downlink main carrier to carry.

When M=1, the base station is according to the transmission mode of downlink main carrier to carry, on the PUCCH of this descending sub frame correspondence format 1a/1b channel resource, transmit according to PUCCH format 1a(single codeword) or the many codeword transmission of PUCCH format 1b() transmission plan reception ACK/NACK information, every bit ACK/nack message is represented the feedback information of this each code word of descending sub frame, and the base station is that the code word of NACK retransmits to feedback information; Described PUCCH format 1a/1b channel resource is the minimum CCE acquisition of base station according to the PDCCH in this descending sub frame, maybe when the data of this descending sub frame were the SPS PDSCH of no corresponding PDCCH, this channel resource was a semi-static channel resource of the TPC indication of the PDCCH of this SPS PDSCH of activation; If do not detect ACK/NACK information on above-mentioned this channel resource in base station, then the base station judges that UE loses the descending sub frame of dispatching on the downlink main carrier to carry, retransmits this subframe.

Situation 1: as M〉1 the time: the base station needs on the SR resource of high level configuration according to PUCCH format 1b transmission plan, and accordingly at the most on M PUCCH format 1b channel resource according to PUCCH format 1b with channel selection transmission plan blind check ACK/NACK information; If the base station determines that ACK/NACK information is in the SR transmitted over resources, then the base station determines that there is sure SR simultaneously in UE, promptly there is dispatch request, obtain the correct packet number that receives of 2 bit b (0) and b (1) expression, as shown in table 5, if misfit with actual schedule, then the base station retransmits all scheduling subframes; If the base station determines that ACK/NACK information is in PUCCH format 1b transmitted over resources, then the base station determines that there is not dispatch request in UE, shine upon form table 1 to table 3(or table 9 according to ACK/NACK, consistent the getting final product of mapping form with the UE employing) obtain M bit ACK/NACK feedback information, the feedback information of each descending sub frame of dispatching on the corresponding respectively downlink main carrier to carry is that the subframe of NACK/DTX retransmits to feedback information; Perhaps, the base station also can be detected the SR resource earlier, if there is the ACK/NACK transmission in judgement, does not then need further to detect PUCCH format 1b channel resource; Otherwise, further detect PUCCH format 1b channel resource again; If the base station does not all detect ACK/NACK information on above-mentioned channel resource, then the base station judges that there is not dispatch request in UE, and loses all descending sub frames of dispatching on the downlink main carrier to carry, retransmits all subframes of dispatching on the downlink main carrier to carry.

Situation 2: when M=1, the base station needs on the SR resource of high level configuration according to PUCCH format 1b transmission plan, and on the corresponding PUCCH format 1a/1b channel resource according to the transmission of PUCCH format 1a(single codeword) or the many codeword transmission of PUCCH format 1b() transmission plan blind check ACK/NACK information; If the base station determines that ACK/NACK information is in the SR transmitted over resources, then the base station determines that there is sure SR simultaneously in UE, promptly there is dispatch request, obtain the correct packet number that receives of 2 bit b (0) and b (1) expression, as shown in table 5, if misfit with actual schedule, then the base station retransmits all scheduling subframes; If the base station determines that ACK/NACK information is in PUCCH format 1a/1b transmitted over resources, then the base station determines that there is not dispatch request in UE, obtain 1(single codeword transmission) or the many codeword transmission of 2() bit ACK/nack message represents the ACK/NACK information of each code word on the downlink main carrier to carry, is that the code word of NACK retransmits to feedback information; Perhaps, the base station also can be detected the SR resource earlier, if there is the ACK/NACK transmission in judgement, does not then need further to detect PUCCH format 1a/1b channel resource; Otherwise, further detect PUCCH format 1a/1b channel resource again; If the base station does not all detect ACK/NACK information on above-mentioned channel resource, then the base station judges that there is not dispatch request in UE, and loses the descending sub frame of dispatching on the downlink main carrier to carry, retransmits this subframe.

Situation 1: if high-rise configuration UE supports ACK/NACK and cycle CSI to transmit simultaneously at same sub-frame of uplink, under conventional CP, the base station according to the transmission mode of downlink main carrier to carry directly on the PUCCH format 2/2a/2b resource of high level configuration according to the conventional CP of PUCCH format 2a(, single codeword is transmitted) or the conventional CP of PUCCH format 2b(, many codeword transmission) or PUCCH format 2(expansion CP) transmission plan receives ACK/NACK, obtain the correct packet number that receives of 2 bit b (0) and b (1) expression, as shown in table 5, if misfit with actual schedule, then the base station retransmits all scheduling subframes; If the base station does not all detect ACK/NACK information on above-mentioned PUCCH format 2/2a/2b channel resource, then the base station judges that UE loses all row subframes of dispatching on the downlink main carrier to carry, retransmits the subframe of dispatching on the downlink main carrier to carry.

Situation 2: if high-rise configuration UE does not support ACK/NACK and cycle CSI to transmit simultaneously at same sub-frame of uplink, then the base station judges that UE abandons cycle CSI information, only the situation according to above-mentioned transferring ACK/nack message receives ACK/NACK, being above-mentioned M〉PUCCH format 1a/1b scheme when 1 PUCCH format 1b with channel selection scheme and M=1 receives ACK/NACK information, do not give unnecessary details at this; If the base station does not all detect ACK/NACK information on above-mentioned PUCCH format 1a/1b channel resource, then the base station judges that UE loses all descending sub frames of dispatching on the downlink main carrier to carry, retransmits the subframe of dispatching on the downlink main carrier to carry.。
