Description

A kind of ACK/NACK feedback information transmission methods and relevant device

Technical field

The present invention relates to communication technical field, more particularly to a kind of ACK/NACK feedback information transmission methods and correlation to set It is standby.

Background technology

First, existing LTE frame structures (LTE Rel-8/9/10/11/12/13)

Existing Long Term Evolution (Long Term Evolution, LTE) FDD (Frequency Division Duplex, FDD) system uses frame structure Class1 (Frame Structure Type 1, abbreviation FS1).In FDD system, on Row and downlink transfer use different carrier frequencies, and uplink and downlink transmission uses identical frame structure.It is as shown in Figure 1 FS1 Structural representation, on each carrier, the radio frames of a 10ms length include 10 1ms subframes, and each subframe is divided into The time slot of two 0.5ms length, transmission time interval (the Transmission Time that uplink and downlink data are sent Interval, TTI) it is 1ms.

Existing LTE time division duplexs (Time Division Duplex, TDD) system uses frame structure type 2 (Frame Structure Type 2, abbreviation FS2).In a tdd system, uplink and downlink transmission uses the different subframes in identical frequency Or different time-gap.It is illustrated in figure 2 FS2 structural representation.The radio frames of each 10ms length are by two 5ms length in FS2 Field form, each field includes the subframe of 5 1ms length.Subframe in FS2 is divided into three classes, and is respectively：Descending sub frame, Sub-frame of uplink and special subframe, each special subframe by downlink transfer time slot (Downlink Pilot Time Slot, DwPTS), protection interval (Guard Period, GP) and upstream transmission time slot (Uplink Pilot Time Slot, UpPTS) Three parts are formed.Wherein, DwPTS can be used for transmission descending pilot frequency, downlink service data and descending control signaling；GP, which is not transmitted, to be appointed What signal；UpPTS can only be used to transmit accidental access signal and detection reference signal (Sounding Reference Symbol, SRS), it is impossible to be used in transmission uplink service or ascending control information.At least one descending sub frame and at least 1 are included in each field Individual sub-frame of uplink, and most 1 special subframe.The 7 kinds of ascending-descending subframes configuration modes supported in FS2 are as shown in table 1.

Table 1：Uplink-downlink configuration

2nd, existing LTE FDD/TDD ACK/NACK feedback sequential

In LTE Rel-8 systems, for FDD system, due to having ascending resource in each subframe, therefore, numbering n Descending sub frame ACK/NACK feedback informations numbering be n+k sub-frame of uplink in transmit.

For TDD system, because downstream transmission shares frequency domain resource, it is necessary to carry out ascending-descending subframes as shown in table 1 Division, therefore, the ACK/NACK feedback informations of different descending sub frames may need to transmit in same sub-frame of uplink, such as table 2 It is shown, the set K according to corresponding to numbering is n sub-frame of uplink：{k₀,k₁,…k_M-1In each element, it may be determined that need Descending sub frame (including the descending sub frame that numbering is n-k, including the special subframe of ACK/NACK feedbacks are carried out in the sub-frame of uplink Inside), then same sub-frame of uplink needs to feed back the ACK/NACK feedback informations of M descending sub frame, and M is the element in set K Number, different sub-frame of uplink and different TDD uplink-downlink configuration values are not necessarily identical.

Table 2Downlink association set index K:{k₀,k₁,…k_M-1}for TDD

It should be noted that the numbering in table 2 is in units of radio frames, the subframe that numbering is n-k, such as subframe number N-k is less than zero, then shows that the subframe belongs to previous radio frames.

When carrying out carrier aggregation, a terminal may be simultaneously operated on multiple carrier waves, but can only be in partial carrier wave Transmission ACK/NACK feedback letters in Physical Uplink Control Channel (Physical Uplink Control Channel, PUCCH) Breath, such as main member carrier (Primary Component Carrier, PCC).Therefore, terminal is gone back in a sub-frame of uplink Need to feed back ACK/NACK feedback informations corresponding to multiple carrier waves.When the carrier wave of terminal polymerization is FDD carrier waves, each carrier wave On ACK/NACK feedback sequential be all to be carried out according to n+4.When the carrier wave of terminal polymerization is TDD carrier waves, if all The TDD uplink-downlink configurations of TDD carrier waves are identical, then the ACK/NACK feedback sequential on each carrier wave is according to the TDD up-downgoings What the feedback sequential corresponding to configuration shown in table 2 was carried out；If the TDD uplink-downlink configurations for the TDD carrier waves being polymerize are different, need TDD up-downgoings are referred to secondary member carrier (Secondary Component Carrier, SCC) definition according to ad hoc rules Configuration, ACK/NACK feedbacks are carried out according to reference to the feedback sequential in the table 2 corresponding to TDD uplink-downlink configurations.When terminal polymerize Carrier wave not only comprising FDD carrier waves but also when including TDD carrier waves, if FDD carrier waves as PCC, the ACK/NACK on each carrier wave Feeding back sequential is carried out according to n+4, if TDD carrier waves are needed according to ad hoc rules, to secondary member carrier as PCC (SCC, Secondary Component Carrier) definition refers to TDD uplink-downlink configurations, according to reference to TDD uplink-downlink configurations Feedback sequential in corresponding table 2 carries out ACK/NACK feedbacks.

In later release (Release), also further support polymerization carrier wave being divided into multiple carrier wave sets, in each carrier wave ACK/NACK feedbacks are carried out by PUCCH on a carrier wave in group, it is now, right according to its polymerization carrier wave institute in each carrier wave set One kind in the above situation answered, determine the feedback sequential of the SCC in the carrier wave set.

When each carrier wave of terminal polymerization uses FDD feedback sequential, transmitted in same sub-frame of uplink Whether the bit number of ACK/NACK feedback informations is according to configuration carrier number, the transmission mode of each carrier wave and using space merging To determine, i.e. ACK/NACK bit numbersWherein, when carrier wave i is single TB transmission modes or more TB transmission modes and is adopted When being merged with space, C_i=1, otherwise, i.e., when carrier wave i is more TB transmission modes and does not use space to merge, C_i=2.Work as terminal When at least one carrier wave of polymerization uses TDD feedback sequential, then the ACK/NACK transmitted in same sub-frame of uplink feeds back The bit number of information according to configuration carrier number, above-mentioned M values, the transmission mode of each carrier wave and whether using space merging come true Determine, i.e. ACK/NACK bit numbersWherein, when carrier wave i is single TB transmission modes or more TB transmission modes and is adopted When being merged with space, C_i=1, otherwise, i.e., when carrier wave i is more TB transmission modes and does not use space to merge, C_i=2, M_iTo carry The descending sub frame number of the progress ACK/NACK feedbacks in same sub-frame of uplink is needed corresponding to ripple i.

In LTE system, existing transmission is all defined with TTI=1ms, when the TTI length using non-1ms When, the TTI length of downlink transfer can change, in addition, base station can also dynamically adjust the anti-of terminal transmission ACK/NACK Time delay is presented, therefore, the downlink transfer number that ACK/NACK feedbacks are carried out in same up TTI can be with TTI length not Same, base station instruction time delay Different Dynamic change, so as to the feedback window in the absence of a fixed size, i.e., without fixed M Value, therefore, when in same up TTI carry out ACK/NACK feedbacks multiple downlink transfers in packet loss be present when, terminal and The cause that understood differently to the length of ACK/NACK feedback sequences is caused base station error resolution ACK/NACK to feed back by base station, so as to shadow Ring downlink throughput capacity.ACK/NACK number of bits of feedback is determined according to configuration carrier wave, transmission mode, M sizes in current mechanism Method is no longer applicable, it is necessary to studying new method ensures that terminal is consistent to ACK/NACK feedback bits number comprehensions with base station, so that Ensure ACK/NACK correct parsing, avoid descending re-transmission as far as possible.

It should be noted that the downlink transfer referred in the embodiment of the present invention, can be short TTI (being referred to as sTTI) transmission, Can also be that tradition (i.e. 1ms) TTI is transmitted, the indicating downlink semi-continuous scheduling (Semi- mentioned in the embodiment of the present invention Persistent Scheduling, SPS) resource release down control channel, the descending control of indicating downlink SPS resource actives Channel processed, Physical Downlink Shared Channel (Physical Downlink Shared Channel, PDSCH) can be that short TTI is passed It is defeated, or tradition (i.e. 1ms) TTI is transmitted.

In the embodiment of the present invention, as shown in figure 3, end side carries out the method detailed flow of ACK/NACK transmission of feedback information It is as follows：

Step 301：Terminal determines ACK/NACK configured informations, wherein, comprise at least and use in the ACK/NACK configured informations In it is determined that the terminal transmission ACK/NACK feedback informations bit number information.

In the embodiment of the present invention, ACK/NACK configured informations are used for the total of the ACK/NACK feedback informations of indicating terminal to report Downlink transfer sum corresponding to the ACK/NACK feedback informations that bit number or terminal report；Or ACK/NACK configured informations The total bit number or terminal of ACK/NACK feedback information of the instruction terminal on each carrier wave in polymerization/activation carrier wave are poly- Downlink transfer sum corresponding to the ACK/NACK feedback informations on each carrier wave in conjunction/activation carrier wave.

Specifically, if ACK/NACK configured informations are used for the total bit number of the ACK/NACK feedback informations of indicating terminal to report Or the downlink transfer sum corresponding to the ACK/NACK feedback informations that report of terminal, terminal determine ACK/NACK configured informations, wrapped Include but be not limited to following several method：

Method 1, terminal produces ACK/NACK feedback informations, using the bit number of ACK/NACK feedback informations as ACK/NACK Configured information, or using the downlink transfer sum corresponding to ACK/NACK feedback informations as ACK/NACK configured informations.

Specifically, downlink transfer sum can be embodied in the control channel of indicating downlink SPS resources release, PDSCH Total number, SPS PDSCH can also be included；It can be converted between downlink transfer sum and total bit number, such as can basis The transmission mode of each downlink transfer, whether carry out the total bit number that the information such as space merging determine ACK/NACK.It is following The explanation of downlink transfer sum can be found in description herein in embodiment, be not repeated.

Method 2, terminal produce ACK/NACK feedback informations, pre-defined or that high-level signaling is pre-configured with multiple Selection is not less than a value of the bit number of ACK/NACK feedback informations in the bit number of ACK/NACK feedback informations, as ACK/ NACK configured informations, or select to be not less than in multiple downlink transfer sums pre-defined or that high-level signaling is pre-configured with One value of the downlink transfer sum corresponding to ACK/NACK feedback informations, as ACK/NACK configured informations.

Specifically, corresponding to method 2, when the sequence length of ACK/NACK feedback informations is less than ACK/NACK configured informations institute During the ACK/NACK total bit numbers of instruction, or when the downlink transfer sum corresponding to ACK/NACK feedback informations is less than ACK/NACK During downlink transfer sum indicated by configured information, terminal mends NACK at the sequence end of ACK/NACK feedback informations, until The sequence length of ACK/NACK feedback informations is equal to ACK/NACK total bit numbers or ACK/ indicated by ACK/NACK configured informations The ACK/NACK total bit numbers corresponding to downlink transfer sum indicated by NACK configured informations.

Method 3, terminal-pair each polymerize (or activation) carrier wave and produce ACK/NACK feedback informations, will each polymerize (or swash It is living) the product conduct of the maximum and the number for polymerizeing (or activation) carrier wave of the bit numbers of the ACK/NACK feedback informations of carrier wave ACK/NACK configured informations, or the downlink transfer that will each polymerize corresponding to the ACK/NACK feedback informations of (or activation) carrier wave are total Several maximums with polymerize/product of the number of activation carrier wave is as ACK/NACK configured informations.

Specifically, corresponding to method 3, when the bit number of the ACK/NACK feedback informations an of polymerization (or activation) carrier wave is small When the maximum of the bit number of the ACK/NACK feedback informations of each polymerization (or activation) carrier wave, or when a polymerization (or swashs It is living) the downlink transfer sum corresponding to the ACK/NACK feedback informations of carrier wave is less than the ACK/ of each polymerization (or activation) carrier wave During the maximum of the downlink transfer sum corresponding to NACK feedback informations, terminal is anti-in the ACK/NACK of polymerization (or activation) carrier wave NACK is mended at the sequence end of feedforward information, until the sequence length of the ACK/NACK feedback informations of polymerization (or activation) carrier wave is equal to every The maximum of the bit number of the ACK/NACK feedback informations of individual polymerization (or activation) carrier wave or each polymerization (or activation) carrier wave ACK/NACK total bit numbers corresponding to the maximum of downlink transfer sum corresponding to ACK/NACK feedback informations.

Method 4, terminal produces ACK/NACK feedback informations, by the down control channel corresponding to ACK/NACK feedback informations ACK/NACK feedback information bits number corresponding to the downlink transfer sum of middle instruction as the ACK/NACK configured informations, or Using downlink transfer sum as the ACK/NACK configured informations.

For example, T-DAI (Total Downlink Assignment Index, sum are included in each down control channel Descending distribution index), for indicating untill present sub-frame/TTI, the downlink transfer of scheduling is amounted on all configuration carrier waves Sum, each TTI on each carrier wave is a downlink transfer；During for carrier aggregation, same time domain position (such as subframe Or TTI) on all carrier waves on T-DAI it is identical, T-DAI on different time domain position can be different.

Specifically, if ACK/NACK configured informations instruction terminal is on each carrier wave in polymerization (or activation) carrier wave ACK/NACK feedback letter of the total bit number or terminal of ACK/NACK feedback informations on each carrier wave in polymerization/activation carrier wave The corresponding downlink transfer sum of breath, terminal determine ACK/NACK configured informations, including but not limited to following several method：

Method 5, terminal-pair each polymerize (or activation) carrier wave and produce ACK/NACK feedback informations, will each polymerize (or swash It is living) bit numbers of the ACK/NACK feedback informations of carrier wave is used as in ACK/NACK configured informations to that should polymerize (or activation) load The configured information of ripple, or the downlink transfer sum that will each polymerize corresponding to the ACK/NACK feedback informations of (or activation) carrier wave are made For the configured information to that should polymerize/activate carrier wave in ACK/NACK configured informations.

Method 6, terminal-pair each polymerize (or activation) carrier wave and produces ACK/NACK feedback informations, pre-defining or high Ratio of the selection not less than ACK/NACK feedback informations in the bit number for multiple ACK/NACK feedback informations that layer signaling is pre-configured with One value of special number, as the configured information to (or activation) carrier wave should be polymerize in ACK/NACK configured informations, or pre- Selection is right not less than ACK/NACK feedback informations institute in multiple downlink transfer sums that first define or high-level signaling is pre-configured with One value of the downlink transfer sum answered, as the instruction to (or activation) carrier wave should be polymerize in ACK/NACK configured informations Information.

Specifically, corresponding to method 6, when the sequence length of the ACK/NACK feedback informations an of polymerization (or activation) carrier wave Less than a polymerization/activation carrier wave indicated by ACK/NACK configured informations ACK/NACK total bit numbers when, or when one it is poly- Close the downlink transfer sum corresponding to the ACK/NACK feedback informations of (or activation) carrier wave and be less than ACK/NACK configured informations meaning During the downlink transfer sum of a polymerization/activation carrier wave shown, ACK/NACK of the terminal in this polymerization (or activation) carrier wave NACK is mended at the sequence end of feedback information, until the sequence length of the ACK/NACK feedback informations of this polymerization (or activation) carrier wave Degree is equal to the ACK/NACK total bit numbers or ACK/ of this polymerization (or activation) carrier wave indicated by ACK/NACK configured informations ACK/NACK corresponding to the downlink transfer sum of this indicated by NACK configured informations polymerization (or activation) carrier wave always than Special number.

Wherein, terminal produces ACK/NACK feedback informations, or terminal-pair each polymerize (or activation) carrier wave and produces ACK/ NACK feedback informations, including but not limited to following two implementations：

Mode one, DAI of the terminal according to corresponding to the downlink transfer in same moment feeding back ACK/NACK feedback informations, Produce ACK/NACK feedback informations.

Specifically, in the downlink transfer of same moment feeding back ACK/NACK feedback informations, including the descending biography received Downlink transfer defeated and that packet loss is may determine that according to DAI, can be that ACK/NACK is ranked up based on DAI, and pass through DAI Judge packet loss, to judging that the position of packet loss produces NACK, now DAI is counter；If only one polymerize carrier wave, for when Domain counter, i.e., TTI adds up one by one in time domain；Can be time domain progress after first frequency domain if polymerizeing multiple carrier waves counter。

Specifically, DAI can also be further divided into C-DAI (Counter DAI, the descending distribution index of numeration) and T- DAI, C-DAI have DAI functions described above, and T-DAI is used to indicate untill present sub-frame/TTI, is carried in all configurations Amount to the sum of the downlink transfer of scheduling on ripple, therefore when the length of ACK/NACK feedback informations according to caused by C-DAI is less than During length indicated by T-DAI, NACK is supplemented behind.

Mode two, terminal according to the TTI of the downlink transfer in same moment feeding back ACK/NACK feedback informations numbering and/ Or process number and/or carrier index, produce ACK/NACK feedback informations.

Specifically, each ACK/NACK feedback bits are arranged according to TTI numberings and/or process number and/or carrier index Sequence, each ACK/NACK feedback bits carry each self-corresponding TTI numberings and/or process number and/or carrier index respectively.

In the embodiment of the present invention, need to carry out when the Physical Downlink Control Channel without corresponding down control channel be present When ACK/NACK feeds back, ACK/NACK total bit numbers or downlink transfer sum plus 1 indicated by ACK/NACK configured informations.

Specifically, when presence needs progress ACK/NACK anti-without the Physical Downlink Shared Channel of corresponding down control channel Feedback, the ACK/NACK feedback informations for referring at the time of ACK/NACK transmission of feedback information while SPS PDSCH being present need to transmit When, the transmission time of SPS PDSCH ACK/NACK feedback informations can be determined implicitly or according to instruction according to feedback sequential Feedback delay instructions field in the down control channel of SPS resource actives determines；Therefore, once terminal is configured for SPS industry Business, then always carry out ACK/NACK feedbacks in fixed position.

Specifically, when not accounting for SPS PDSCH when ACK/NACK feedback sequences produce, for example, according to T-DAI Indicated downlink transfer sum determines that the downlink transfer sum of now T-DAI instructions is only released including indicating downlink SPS resources The down control channel put and the PDSCH for having corresponding down control channel, not including SPS PDSCH, then need feeding back Increase SPS PDSCH feedback information quantity on the basis of information sum, usually 1 bit；

Now SPS PDSCH ACK/NACK feedback informations are arranged in where ACK/NACK feedback information sequences It can make an appointment, such as always come foremost, it is anti-either always to come ACK/NACK that is last or always coming PCC The foremost of feedforward information is last etc., if terminal arrange with base station it is regular consistent, it is possible to correctly judge SPS PDSCH's The position of ACK/NACK feedback informations.

Step 302：Terminal reports ACK/NACK configured informations and the ACK/ corresponding with the ACK/NACK configured informations NACK feedback informations.

In the embodiment of the present invention, terminal reports ACK/NACK configured informations and corresponding with the ACK/NACK configured informations ACK/NACK feedback informations, including but not limited to following several ways：

First way, ACK/NACK configured informations are transmitted with ACK/NACK feedback informations in identical TTI；Or ACK/NACK configured informations are transmitted in the TTI for being ahead of ACK/NACK feedback informations.

Specifically, when ACK/NACK configured informations are transmitted in the TTI for being ahead of ACK/NACK feedback informations, the TTI is Make an appointment, for example, transmitting ACK/NACK in an adjacent TTI before the TTI of transmission ACK/NACK feedback informations Configured information.

The second way, ACK/NACK configured informations are from ACK/NACK feedback informations in same channel or different letters Transmitted in road.

In which, same channel refers to that channel format is identical and channel resource is also identical；Different channels refer to channel Any one in form and channel resource is different, for example, it may be same channel format, but use different channels to provide Source, or using different channel formats and use different channel resources.

In the embodiment of the present invention, if ACK/NACK configured informations pass with ACK/NACK feedback informations in same channel Defeated, ACK/NACK configured informations take different time domains and frequency domain money from ACK/NACK feedback informations respectively on the same channel Source individual transmission.Transmitted for example, ACK/NACK configured informations are always mapped in the specific time domain and frequency domain resource of the channel, and ACK/NACK configured informations and ACK/NACK feedback informations absolute coding/scrambling/modulation etc..More preferably, in order to ensure ACK/ NACK configured informations are parsed before ACK/NACK feedback informations and finished, and ACK/NACK configured informations are mapped to time domain in TTI and leaned on Transmitted on preceding position, such as first symbol.

Specifically, when presence needs progress ACK/NACK anti-without the Physical Downlink Shared Channel of corresponding down control channel During feedback, the base station determines to include under the physics in the ACK/NACK total bit numbers indicated by the ACK/NACK configured informations The Physical Downlink Shared Channel is included in the bit number or downlink transfer sum of the ACK/ANCK feedback informations of row shared channel.

The ACK/NACK processes transmitted are described in detail below by way of several specific embodiments.

First specific embodiment

Terminal is only operated on a carrier wave, and base station side scheduling shares 8 descending short TTI transmission and all entered at the same moment Row ACK/NACK is fed back, and 2 bit DAI, DAI conducts are included in the corresponding down control channel of each descending short TTI transmission Time domain counter (counter), the value more than 4 circulate instruction using the mode of mould 4.

Specifically, when end side receives, in second descending short TTI packet loss, but continuous DAI counter can be passed through Value, judges that second descending short TTI position has packet loss, and short TTI descending to this second produces NACK as feedback information. Terminal base station scheduling last 1 descending short TTI packet loss, and terminal according to schedule information above can not judge below whether Packet loss be present, descending short TTI that end-on receives and the descending short TTI for judging packet loss, according to transmission mode and whether Space, which merges, determines ACK/NACK feedback informations.Such as assume that each descending short TTI transmission is single codeword transmission, then to receiving Each descending short TTI for arriving and judge that the descending short TTI of packet loss respectively produces 1 bit feedback information, and according to DAI counter Order sequence, obtain 7 bit ACKs/NACK feedback informations, be expressed as o1, o2 ..., o7, end side think only 7 it is descending Short TTI transmission needs to carry out ACK/NACK feedbacks.

Specifically, terminal determine ACK/NACK configured informations instruction terminal transmission ACK/NACK information total bit number or Total downlink transfer number, the sum can be the actually detected quantity arrived of terminal, or one selected in predetermined value The individual value closest to actual quantity and more than actual quantity, ACK/NACK configured informations are determined as follows：

The first implementation, the binary bits number made an appointment corresponding to ACK/NACK configured informations, the binary system Bit number is relevant with the scope of the total bit number of the ACK/NACK feedback informations of instruction required for ACK/NACK configured informations, such as Assuming that maximum ACK/NACK total bit numbers or the sum of downlink transfer are no more than 16 bits, then it can arrange ACK/NACK instructions Information is fixed as 4 bit informations, can arrange 1~16 total bit number or total downlink transfer number and 4 bit-binaries transmission sequence The corresponding relation of row, as shown in table 3, so as to obtain the binary transmissions sequence corresponding to total bit number 7 or always downlink transfer number 7 For " 0111 ", directly 7 can also be switched to for binary numeral, such as provide to carry out Binary Conversion to 7-1=6, in a high position 0 is mended, obtains 4 bit transfer sequences " 0111 "；ACK/ of the terminal using above-mentioned 7 bit ACKs/NACK feedback informations as actual transmissions NACK feedback informations.

Second of implementation, it is assumed that always ACK/NACK configured informations are represented using 2 bit-binary information, for super Cross 4 total bit number or total downlink transfer number uses the many-to-one relationship of mould 4, corresponding relation is as shown in table 4, so as to obtain To the binary transmissions sequence " 10 " corresponding to total bit number 7 or total downlink transfer number 7；Terminal is by above-mentioned 7 bit ACKs/NACK ACK/ANCK feedback information of the feedback information as actual transmissions.

The third implementation, multiple ACK/NACK total bit numbers that pre-defined ACK/NACK configured informations can indicate Value or total downlink transfer numerical value, then can useBit ACK/NACK configured informations, A are pre-defined numerical value Number；Such as A numerical value such as a1=4, a2=8, a3=12, a4=16 are pre-defined, 2 bit ACKs/NACK configured informations, Each numerical value and the corresponding relation of 2 bit configured informations are as shown in table 5, and selection wherein one is closest and is more than above-mentioned ACK/ The numerical value of NACK number of bits of feedback or total downlink transfer number, then select a2=8, obtains 2 bit ACKs/NACK configured informations and is “01”；Now, because the ACK/NACK total bit numbers indicated by ACK/NACK configured informations or total downlink transfer number are more than reality Bit number or downlink transfer number, then need above-mentioned caused 7 bit ACKs/NACK feedback informations o1, o2 ..., o7 ends mend 1 bit NACK, obtain 8 bit ACKs/NACK feedback informations o1, o2 ..., ACK/ANCK feedback informations of the o8 as actual transmissions.

In the specific embodiment, the transmission means of ACK/NACK configured informations includes but is not limited to following two methods：

Method 1：ACK/NACK configured informations are transmitted with ACK/NACK feedback informations on identical channel resource.

It is for example, anti-using the sPUCCH transmission ACK/NACK configured informations and ACK/NACK of the transmission structure based on PUSCH Feedforward information, it is assumed that sPUCCH is transmitted using 7 symbols (such as SC-FDMA symbols, similarly hereinafter), and ACK/NACK configured informations are mapped to Transmitted on first symbol, ACK/NACK feedback informations are mapped on follow-up 6 symbols and transmitted.As shown in Figure 5 a, it is assumed that 1 RB transmission is taken on sPUCCH frequency domains, then by 4 bit ACKs obtained under the first implementation /NACK configured informations or the 2nd, the 2 bit ACKs/NACK configured informations obtained under three kinds of implementations (can use repeated encoding, RM by channel coding Coding etc., can also use TBCC+CRC modes, if there is CRC, then CRC bits be included in coding information, similarly hereinafter) and modulation After (such as QPSK modulation, similarly hereinafter), it is mapped on 12 RE of frequency domain on first symbol, by above-mentioned first and second kind of realization side 8 bit ACKs/NACK feedback informations under 7 bit ACKs/NACK feedback informations or the third implementation under formula pass through channel After coding and modulation, it is mapped on 12 RE of frequency domain on remaining 6 symbol, such as domain mapping when after first frequency domain, or it is on the contrary； Terminal sends ACK/NACK configured informations and ACK/NACK feedback informations simultaneously in the sTTI on same sPUCCH, should SPUCCH channel resource, such as the information of RB positions etc, can be notified in descending control signaling or high-level signaling it is pre- First configure.

In another example using based on permanent envelope zero auto-correlation sequence (Const Amplitude Zero Auto- Corelation, CAZAC) sequence sPUCCH transformats, the CAZAC sequences difference on which part symbol or frequency domain resource For one kind in loading ACK/NACK configured informations and ACK/NACK feedback informations.

Method 2：ACK/NACK configured informations are transmitted from ACK/NACK feedback informations on different channel resources.

For example, ACK/NACK feedback informations are transmitted using the sPUCCH of the transmission structure based on PUSCH, it is assumed that sPUCCH makes 1 resource block (Resource Block, RB) transmission is taken with 7 symbol transmissions, on sPUCCH frequency domains, then by above-mentioned first, 8 bit ACKs/NACK feedback letters under 7 bit ACKs/NACK feedback informations or the third implementation under two kinds of implementations Cease after Channel Coding and Modulation, the 12 resource unit (Resource of frequency domain being mapped on 7 symbols of the sPUCCH Element, RE) on, domain mapping when can be after first frequency domain, or it is on the contrary.ACK/NACK configured informations can also use identical Transmission structure transmission, symbol lengths can be identical or different from the sPUCCH of ACK/NACK transmission of feedback information such as fixed Justice is 2 symbol lengths, and 1 RB transmission is taken on frequency domain, then by 4 bit ACKs obtained under the first above-mentioned implementation / 2 bit ACKs/NACK the configured informations obtained under NACK configured informations or above-mentioned second and third kind of implementation pass through channel coding After modulation, it is mapped on 12 RE of frequency domain using the sPUCCH of 2 symbol lengths and transmits.Loading ACK/NACK feedback informations SPUCCH and the sPUCCH of loading ACK/NACK configured informations can be transmitted in identical time-domain position.Such as loading ACK/ 2 symbols shared by the sPUCCH of NACK configured informations and 7 shared by the sPUCCH of loading ACK/NACK feedback informations The first two symbol aligned in symbol, different frequency domain resource (such as RB) transmission is taken on frequency domain, as shown in Figure 5 b, can also It is not overlapping in time domain, such as 2 symbols shared by the sPUCCH of loading ACK/NACK configured informations are in loading ACK/NACK Sent before 7 symbols shared by the sPUCCH of feedback information, as shown in Figure 5 c.

In another example ACK/NACK feedback informations are transmitted using the sPUCCH of the transmission structure based on PUSCH, detailed process is same On.ACK/NACK configured informations use the transmission structure of CAZAC sequences, it is assumed that are transmitted using 2 symbol lengths, frequency domain takes 1RB.2 four phase phases are obtained after 4 bit ACKs obtained under the first implementation /NACK configured informations are directly modulated Keying (Quadrature Phase Shift Keying, QPSK) modulation symbol is moved, is carried on different sPUCCH transmission respectively It is transmitted on symbol, i.e., after first QPSK modulation symbol is multiplied with the CAZAC sequences by cyclic shift, is mapped to Transmit on sPUCCH first symbol, after second QPSK modulation symbol is multiplied with the CAZAC sequences by cyclic shift, reflect It is mapped on sPUCCH second symbol and transmits, or, if sPUCCH takes 2 or more RB transmission, can also hold respectively Be loaded in different sPUCCH frequency domain resources and be transmitted, i.e. first QPSK modulation symbol and the CAZAC Jing Guo cyclic shift After sequence is multiplied, it is mapped on sPUCCH first RB and transmits, second QPSK modulation symbol is with passing through cyclic shift After CAZAC sequences are multiplied, it is mapped on sPUCCH second RB and transmits.2 bits that will be obtained under second and third kind of implementation ACK/NACK configured informations obtain 1 QPSK modulation symbol after being directly over modulation, with the CAZAC sequence phases Jing Guo cyclic shift It is mapped on sPUCCH each symbol and frequency domain resource and transmits after multiplying.

In method 2, ACK/NACK feedback informations can also use CAZAC sequences transmission structure transmit, concrete mode with The transmission of ACK/NACK configured informations is similar, and only original bit number is different, obtained QPSK modulation symbols number it is different and .

In the specific embodiment, base station side, ACK/NACK instruction letters are received and parsed through according to scheme corresponding with end side Breath, the total bit number of ACK/NACK feedback informations is determined according to ACK/NACK configured informations, receives and solves according to the total bit number ACK/NACK feedback informations are analysed, for first and second kind of implementation, determine that total bit number is 7 according to ACK/NACK configured informations Bit, receive to obtain 7 bit ACKs/NACK feedback informations according to 7 bit informations, so as to judge that terminal is actually only fed back Preceding 7 sTTI feedback information, last sTTI end sides packet loss, base station are lost according to ACK/NACK information and judgement Bag situation determines to need the descending short TTI retransmitted；For the third implementation, according to ACK/NACK configured informations determine always than Special number is 8 bits, receives to obtain 8 bit ACKs/NACK feedback informations according to 8 bit informations, although base station can not judge that terminal exists Scheduling it is last whether packet loss, but the feedback information of afterbody occupy-place is all NACK, and base station need not judge whether that packet loss also can be according to NACK does retransmission process, and base station can be extracted according to the scheduling of reality from the ACK/NACK feedback information sequences received Go out corresponding feedback information (i.e. if the length of ACK/NACK feedback information sequences exceedes the downlink transfer institute of base station actual schedule Corresponding ACK/NACK, then the feedback information of afterbody is invalid, without using), now, base station 8 descending biographies due to actual schedule It is defeated, then it is assumed that 8 bit feedback information are all effective information, correspond to 8 transmission respectively, base station determines need according to ACK/NACK information The descending short TTI to be retransmitted, wherein the 8th bit feedback information is NACK, it is in the 8th transmission although base station can not judge terminal No packet loss, but due to occupy-place NACK, base station still can retransmit the 8th transmission.

In table 5, more predefined values can also be defined, multiple values are multiplexed same binary condition to be indicated. Wherein, indicated for the ACK/NACK shown in table 4 (or in table 5 also when by the way of multiple corresponding binary conditions of value) The multiplexing indicating mode of information, because it was assumed that it is minimum probability event that terminal, which continuously loses 4 packets, therefore always assumes that end End will not continuously lose 4 data above bags, therefore, can judge that multiplexing refers to according to the packet sum that base station is dispatched in itself Which value is the value shown be.For example, in the specific embodiment, base station scheduled 8 descending short TTI transmission in itself to be needed while enters Row ACK/NACK feeds back, and when the ACK/NACK configured informations that parsing obtains are " 10 ", can only be judged as no more than 8 and be not less than 8-4=4 value, so can only be " 7 " this value corresponding to " 10 " state, the more corresponding judgment principles of following presence are herewith Place, is repeated no more.

The sum of the ACK/NACK total bit numbers of table 3 or downlink transfer number and the corresponding relation of 4 bit-binaries transmission information

The sum of the ACK/NACK total bit numbers of table 4 or downlink transfer number and the corresponding relation of 2 bit-binaries transmission information

The sum of the ACK/NACK total bit numbers of table 5 or downlink transfer number and the corresponding relation of 2 bit-binaries transmission information

Second specific embodiment

As shown in fig. 6, terminal is carrier aggregation mode of operation, it is assumed that is operated on two carrier waves, base station side is on carrier 1 Scheduling shares 4 descending short TTI transmission and all carries out ACK/NACK feedbacks at the same moment, it is assumed that each descending short TTI length Spend identical, be all 7 symbols, base station dispatch on carrier 2 share 8 descending short TTI transmission all with 4 on carrier wave 1 The short TTI of row transmits same moment progress ACK/NACK feedbacks, it is assumed that each descending short TTI length is identical, is all 2 symbols Number, comprising 2 bit DAI, DAI as time domain counter in the corresponding down control channel of each descending short TTI transmission, Value more than 4 circulates instruction using the mode of mould 4.

In the specific embodiment, the process that terminal receives is as follows：

Second descending short TTI packet loss on carrier 1, but can judge to carry by continuous DAI counter values There is packet loss in second descending short TTI position on ripple 1, NACK is produced as feedback information to the second descending short TTI.Terminal Last 1 of base station scheduling descending short TTI packet loss on carrier 1, and behind terminal can not be judged according to schedule information above With the presence or absence of packet loss.Descending short TTI that end-on the receives and descending short TTI for judging packet loss, according to transmission mode and Whether space, which merges, determines ACK/NACK feedback informations.Such as assume that each descending short TTI transmission is single codeword transmission, then it is right Each descending short TTI for receiving and judge that the descending short TTI of packet loss respectively produces 1 bit feedback information, and according to DAI Counter order sequence, obtains 3 bit ACKs/NACK feedback informations o_1,1、o_1,2、o_1,3, end side is thought on carrier 1 only There are 3 descending short TTI transmission to need to carry out ACK/NACK feedbacks.

Last 2 of base station scheduling descending short TTI packet losses on carrier 2, and terminal can not according to schedule information above Judge to whether there is packet loss below, the descending short TTI that end-on receives, according to transmission mode and whether space merges determination ACK/NACK feedback informations.For example, it is assumed that each descending short TTI transmission is single codeword transmission, then to receive it is each under The short TTI of row respectively produces 1 bit feedback information, and is sorted according to DAI counter order, obtains 2 bit ACKs/NACK feedbacks Information o_2,1、o_2,2…o_2,6, end side thinks only have 6 descending short TTI transmission to need to carry out ACK/NACK feedbacks on carrier 2.

3rd specific embodiment

As shown in fig. 7, terminal is carrier aggregation mode of operation, it is assumed that is operated on 6 carrier waves, base station side is in each carrier wave The short TTI transmission situation that the needs of upper scheduling carry out ACK/NACK feedbacks at the same moment is as shown in Figure 7, it is assumed that each descending Short TTI length is identical, is all 7 symbols, and each descending short TTI transmission is transmitted for single codeword, each descending short TTI transmission All comprising 2 bit C-DAI and 2 bit T-DAI, C-DAI as time domain after first frequency domain in corresponding down control channel Counter, T-DAI instruction amount to the TTI sums of scheduling untill current short TTI on all carrier waves, and C-DAI and T-DAI surpass The value for crossing 4 circulates instruction using the mode of mould 4, as shown in table 6 below.

The C-DAI of table 6 and T-DAI value

In the specific embodiment, the process that terminal receives is as follows：

Downlink transfer is received on each carrier wave and short TTI, specific reception condition according to C-DAI as shown in fig. 7, can sentence There is packet loss in the descending short TTI positions of second on carrier wave 1,4 of breaking, the T-DAI=2 in first sTTI may determine that Amount in first sTTI on all carrier waves and scheduled 6 downlink transfers, the T-DAI values in the 2nd sTTI are 3 and arrived Untill second TTI, the downlink transfer number received is amounted on all carrier waves, it can be determined that what T-DAI=3 was represented is to amount to 11 downlink transfers are scheduled, therefore may determine that on carrier wave 6 packet loss be present in the 2nd sTTI；NACK is produced to packet loss position to make For feedback information；But because terminal does not receive any downlink transfer in the 3rd sTTI, therefore carrier wave 1 can not be judged and carried The packet loss on the 3rd sTTI of ripple 2, also just can not be according to total descending indicated by the last T-DAI=1 of base station actual schedule Number 13 is transmitted to determine the bit number of feedback information；Therefore terminal is according to the C-DAI and T-DAI detected, including judges to lose The position of bag, 11 bit ACKs/NACK feedback informations being produced, ACK/NACK feedback informations sort according to C-DAI incremental order, The feedback information of i.e. first sTTI carrier wave 1, first sTTI carrier wave 2 feedback information ... the feedback of first sTTI carrier wave 6 Information, the feedback information of second sTTI carrier wave 1, second sTTI carrier wave 3 feedback information ... second sTTI carrier wave 6 Feedback information；Think that only above-mentioned 11 descending short TTI transmission need to carry out ACK/NACK feedbacks in end side.

Total ACK/NACK number of bits of feedback of ACK/NACK configured informations instruction terminal transmission or the total descending biography detected Defeated number or last T-DAI detected value or the ACK/NACK according to determined by last T-DAI detected Feedback information sum, determine the total bit number or total descending of the ACK/NACK information of ACK/NACK configured informations instruction terminal transmission Number is transmitted, the sum can be the actually detected quantity arrived of terminal, or one selected in predetermined value most connects Nearly actual quantity and as follows more than the value of actual quantity, specific implementation：

The first implementation, similar to the first implementation of the first specific embodiment, make an appointment ACK/NACK Binary bits number corresponding to configured information, as shown in table 3,3 is tabled look-up so as to obtaining total bit number 11 caused by reality or real Total downlink transfer number 11 that border detects or the indicated total downlink transfer number 11 of last T-DAI values or the last T- of general layout Binary transmissions sequence determined by DAI corresponding to total ACK/ANCK number of bits of feedback 11 is " 1010 ", can also directly by 11 subtract and switch to after 1 for binary numeral, mend 0 in a high position, obtain 4 bit transfer sequences " 1010 ".

Second of implementation, similar to second of implementation of the first specific embodiment, it is assumed that always using 2 bits Binary message represents ACK/NACK configured informations, as shown in table 4, so as to obtain total bit number 11 caused by reality or actual inspection The indicated total downlink transfer number 11 of the total downlink transfer number 11 measured or last T-DAI values or the last T-DAI institutes of general layout The binary transmissions sequence " 10 " corresponding to total ACK/ANCK number of bits of feedback 11 determined, or can also be directly T-DAI Value or binary condition are as ACK/NACK configured informations (because such a situation T-DAI definition mode is consistent with table 4).

The third implementation, similar to the third implementation of the first specific embodiment, pre-define ACK/NACK The multiple ACK/NACK total bit numbers values or total downlink transfer numerical value that configured information can indicate, as shown in table 5, are selected wherein One closest to and be more than total bit number 11 caused by above-mentioned reality or the actually detected total downlink transfer number 11 or last arrived Total ACK/ANCK number of bits of feedback 11 determined by the indicated total downlink transfer number 11 of T-DAI values or the last T-DAI of general layout Numerical value, then select a3=12, it is " 10 " to obtain 2 bit ACKs/NACK configured informations.Now, due to ACK/NACK configured informations Indicated ACK/NACK total bit numbers or total downlink transfer number are more than actual bit number or downlink transfer number, then need upper 1 bit NACK is mended at the end of 11 bit ACKs/NACK feedback informations caused by stating, and is obtained 12 bit ACKs/NACK feedback informations and is made For the ACK/NACK feedback informations of terminal actual transmissions.
