Description
Technical field
The present invention relates to a kind of method for several feedback information message of encoding at the mobile radio communicaltions system that uses carrier aggregation.In addition, the present invention relates to a kind of terminal for mobile radio communicaltions system and radio base station.
Background technology
In Long Term Evolution senior (LTE is senior) system, the polymerization in up link and down link respectively of a plurality of component carriers.For instance, for high data rate is provided, transmitting when subscriber equipment (UE) can receive on a plurality of down link component carriers.For a UE, each component carrier is used for launching 1 transmission block (transmitting is 2 transmission blocks for multiple-input and multiple-output (MIMO)).If transmission block successfully detected, UE sends confirmation (ACK) in up link so, and if detect unsuccessfully, send so Negative Acknowledgement (NACK).The position of available value " 1 " represents ACK, and represents NACK by value " 0 ".Therefore,, the in the situation that of carrier aggregation, need to from a UE, launch a plurality of ACK or NACK position in response to the transmission block of launching on different component carriers.
Sometimes, by the concept of community, replace component carrier, polymerization equally can be for community.In polymerization situation, subscriber equipment may be configured with a plurality of Serving cells.Community can provide the communication of up link and down link both direction, therefore can comprise up link and down link component carrier.Can suppose that UE has a main services community (P community), and one or several auxiliary serving cells (S community).Those skilled in the art can use term " community " to replace the component carrier relevant with carrier aggregation equivalently.
Before detected transmission piece, first need to detect downlink control channel, it contains reception data channel and separates the required downlink allocation information of code transmission block.If UE does not correctly receive control channel, UE does not know that its expection receives any data channel so, and it does not send any feedback in up link, no matter is ACK or NACK.This is called as discontinuous transmitting (DTX).ENB knows when expect NACK or ACK, and if eNB carried out data transmission,, after DTX detects, eNB must initial repeating transmission.In MIMO transmission, a downlink control channel contains the distribution for two transmission blocks.Therefore, DTX is applied to two transmission blocks for MIMO simultaneously.
Except losing downlink allocation, the ACK/NACK signaling in up link may be also wrong, and the ACK that for example launched may be received as NACK, or the NACK launching may be received as ACK.NACK may introduce the collapse of mixed automatic retransfer request (HARQ) buffering because of the mistake combination of some transmittings to ACK mistake in receiver, for example, because subscriber equipment (UE) can retransmit by expectability, and base station (eNB in Long Term Evolution (LTE) communication system) dispatches new bag.Unnecessary re-transmission when ACK retransmits because UE does not expect to NACK mistake causes system operation poor efficiency.Therefore, importantly provide sane ACK/NACK signaling.In order to guarantee suitable systematic function, LTE standard has been enumerated the requirement to ACK/NACK error performance.
It is for launching a kind of feasible method of a plurality of confirmations (ACK) and Negative Acknowledgement (NACK) position that channel is selected.By the sequence through Quadrature Phase Shift Keying (QPSK) (or other modulation order symbol) modulation, carry out transmitting, and the channel of the form by sequence and QPSK constellation point selects encoder feedback information.Channel is selected to relate to the selection of sequence, and can in same frequency resource, launch some sequences.That is, the code division multiplex (CDM) by sequence obtains channel.UE once only launches conventionally on a channel.Therefore, owing to only selecting for a subscriber equipment (UE) and launching a sequence, so channel select stick signal to keep UE compared with the useful single-carrier property of low peak average power (PAPR).This feedback principle is for Long Term Evolution (LTE) version 8 of time division duplex (TDD), and wherein from the ACK/NACK of a plurality of downlink subframe, a transmitting in single uplink sub-frames is notified.For LTE AS, also will use channel to select, but in the situation that pass on the ACK/NACK from a plurality of component carriers (being carrier aggregation) to use.This is applicable to reaching 4 ACK/NACK positions, and also comprises Frequency Division Duplexing (FDD) (FDD) situation.Each transmission block needs an ACK/NACK position conventionally, and therefore 4 positions can be corresponding to the configuration that respectively has MIMO transmitting on 2 component carriers.
For the ACK/NACK/DTX information of encoding, need the different conditions of ACK, NACK and DTX and the mapping between channel and QPSK constellation point.These mapping tables are selected to exist because of the channel of the TDD in version 8, but need new mapping for the carrier aggregation in LTE AS, because the various combination of the ACK/NACK/DTX that need to encode, and the availability of channel and reserved by difference.
By means of channel, select emission needle to need code book to the ACK/NACK of carrier aggregation, wherein for each of ACK/NACK/DTX, effectively combine, should distribute a channel and a constellation point, therefore, this scheme needs a mobile radio communicaltions system that uses carrier aggregation.
Summary of the invention
Target of the present invention is to propose a kind of solution to prior art problem, or reduces prior art problem.Therefore, main target is the scheme of feedback information message of the mobile communication system of a kind of applicable use carrier aggregation of design.
According to the present invention, by the method in several feedback information message of encoding with the mobile radio communicaltions system of carrier aggregation, realize described target, described method comprises:
-by several feedback information message described in the incompatible coding of code word set, wherein each feedback information message can be at least the first kind or the second kind, and each code word comprises the channel being selected from A channel, and be selected from a modulation symbol in S modulation symbol.Described method is characterised in that: at least one feedback information message, existence is corresponding at least one code word of the information of the first kind and corresponding at least one code word of the information of the second kind, for described at least one feedback information message, modulation symbol corresponding to the one in described at least one code word of the modulation symbol of the one in described at least one code word of the information of the first kind and information corresponding to the second kind has ultimate range, and wherein said code word comprises same channel and different modulating symbol, and wherein for described at least one feedback information message, at least one in S symbol be not for comprising any code word of described same channel.
Therefore,, by means of the method, be designed for the scheme of the feedback information message in mobile radio communicaltions system.Due to when representing that the symbol of the code word of the information of the first kind and the information of the second kind has largest interval while launching on same channel, therefore guarantee that the possibility that this symbol is obscured each other reduces to minimum.That is, the information of the first kind is sent out but the possibility that is detected as the information of the second kind reduces to minimum.
The present invention relates to following understanding: use channel to select and the code word of the phase information of the symbol launched has asymmetric detection probability, on channel, to have sent energy more simply too much than the phase place of detected symbol because detect on channel.Further recognize: by the feedback information message guaranteeing least to wish to obscure, separated to the full extent aspect its modulation symbol, can utilize in this case above-mentioned characteristic when detecting.
Therefore, the present invention proposes following viewpoint: code book design can affect ACK to NACK and NACK to ACK error probability, channel and constellation point to be distributed to effective ACK/NACK/DTX state so that the error probability of state reduces to minimum, can manage to guarantee that the code word that represents different types of information has largest interval aspect its corresponding modulation symbol.
The invention still further relates to terminal and the radio base station with the method according to this invention with equivalent advantage.
In appended claims, disclose other advantageous embodiment.

Embodiment
Consider one group of A channel (n
pUCCH(0) ..., n
pUCCH) and 2 (A-1)
mmodulation (for QPSK, m=2) is wherein selected 1 channel, and launch 2 on this channel from A channel
mone in individual modulation symbol.Like this, codified is to reaching A2
mthe information of individual state.This signaling method is called as channel and selects.In LTE, channel comprises sequence, and sequence described in QPSK symbol-modulated.In below describing, suppose QPSK symbol, but without loss of generality.
Code word can be defined as to the position (n of channel indexes and QPSK symbol
pUCCH(k), b (0) ..., b (m-1)) (k ∈ 0,1 ..., A-1}, b (i) ∈ 0, cascade 1}).Therefore, code word element can have different alphabets.Each effective code word table shows an information state.Owing to passing on the first element n by selective channel
pUCCH(k), and other element b (0) ..., b (m-1) is passed on by modulation symbol, so detects performance difference between the element in code word.The first element relates to the use of channel, and can detect by energy measuring or by correlator, and modulation symbol must be by the phase-detection of the signal receiving.Conventionally, energy measuring is more more reliable than symbol detection.Therefore, the design of code book must consider that the degree of reliability of code word element is different.Consequence is that error probability (for example, NACK is to ACK or ACK to NACK mistake) is main owing to the error detection to modulation symbol, and will depend on which code word of distribution a certain information of encoding.Therefore, cautiously assigned modulation symbol and channel to reduce error event.
Size arrives the mapping of code word for the code book of N comprises the set of N information state.Conventionally, this packets of information is containing one or several entities of (but being not limited to) ACK, NACK, NACK/DTX or DTX.United state NACK/DTX implies that eNB will carry out re-transmission conventionally.If N≤A2
m, the number of the code word used is not more than the sum of available codeword, so receiver can be determined each coded message state clearly.Each information state can further for example, be comprised of one or several fields (being represented by HARQ-ACK (i)) herein, and wherein each field represents the feedback information for given transmission block.This field is also referred to as feedback information message, and these two terms are used interchangeably.The state of this field can be in ACK, NACK, NACK/DTX or DTX at least any one.If two carrier waves (or community) polymerization, HARQ-ACK (0) can represent the feedback information message for component carrier 0 so, and HARQ-ACK (1) can represent component carrier 1.Informational message can be associated with the transmitting of dynamic dispatching and the data transmission being associated with semi-persistent scheduling release control channel.
In LTE, if use MIMO transmitting, send so 2 transmission blocks, and each transmission block needs its oneself feedback information.Therefore,, if polymerization has 2 carrier waves of MIMO, need so to there are 4 fields code book of (HARQ-ACK (0) to HARQ-ACK (3)).In the polymerization of 4 carrier waves without MIMO, also can use the code book with 4 fields.Similarly, can in not thering is the polymerization of 3 carrier waves of MIMO or the polymerization of 2 carrier waves of one of them carrier wave use MIMO, use the code book with 3 fields.
In order to make error probability, reduce to minimum, because known error mainly detects from wrong modulation symbol, a kind of structure that the present invention comprises code book, wherein at least one HARQ-ACK field (feedback information message), is representing different information and is sharing same channel n
pUCCHcode word between, the modulation symbol of given HARQ-ACK field separates as far as possible far.Suppose that channel is correctly detected, so above-mentioned movement makes NACK to ACK probability, reduce to minimum to ACK and NACK.
This illustrates in following instance, wherein considers, according to the QPSK through Gray code of Fig. 1 and following code book, wherein when appropriate, DTX to be mapped to NACK.When carrying out this mapping, consider the HARQ-ACK (0) and the HARQ-ACK (1) that represent for the feedback information message of the transmitting of MIMO on the first component carrier, and the HARQ-ACK (2) that represents the feedback information message on second component carrier wave.The number of code word is N=8, and uses 3 channels.
Table 1. is for the example code book of the HARQ-ACK with 3 bit multiplexs.
| Entry number | HARQ-ACK(0)、HARQ-ACK(1)、HARQ-ACK(2) | n PUCCH | b(0),b(1) |
| 1 | ACK、ACK、ACK | n PUCCH(2) | 1,1 |
| 2 | ACK、ACK、NACK/DTX | n PUCCH(0) | 1,1 |
| 3 | ACK、NACK、ACK | n PUCCH(0) | 1,0 |
| 4 | ACK、NACK、NACK/DTX | n PUCCH(1) | 1,0 |
| 5 | NACK、ACK、ACK | n PUCCH(1) | 0,1 |
| 6 | NACK、ACK、NACK/DTX | n PUCCH(0) | 0,1 |
| 7 | NACK/DTX、NACK/DTX、ACK | n PUCCH(2) | 0,1 |
| 8 | NACK/DTX、NACK/DTX、NACK/DTX | n PUCCH(2) | 0,0 |
| 9 | DTX、DTX、DTX | N/A | N/A |
Can suppose that the channel using in code book will launch on an antenna port.If UE is equipped with a plurality of antenna ports, so described symbol can be summarized as channel n
(p) pUCCH(k) for antenna port p.Feature of the present invention is not limited to individual antenna port, but can be those skilled in the art and summarize, and makes described feature be applicable to any one in one or several antenna ports.For instance, can consider that every antenna port has a code book, each code book has feature of the present invention.
In order further to understand code book structure, suppose that NACK and NACK/DTX are grouped in together, can further configure code word according to the encoded information of following each HARQ-ACK field.
Table 2. is from the grouping of the code word of the code book in table 1.
The method of putting up with now for some feedback information message of encoding at mobile radio communicaltions system further describes possibility embodiment of the present invention.This system is used above-mentioned carrier aggregation.Can expand and revise described method, in paragraph below, will be described in detail.The citation form of described method comprises that wherein each feedback information message can be at least the first kind or the second kind by several feedback information message described in the incompatible coding of code word set.As mentioned, at least two different types of information can be confirmed (ACK/NACK/DTX) corresponding to the positive or negative of previous sent data.Each code word comprises a channel that is selected from A channel, and a modulation symbol that is selected from S modulation symbol.Now, according to the present invention, come configuration code character code originally, make at least one feedback information message, existence is corresponding at least one code word of the information of the first kind and corresponding at least one code word of the information of the second kind, and for described at least one feedback information message, the modulation symbol of the one in the modulation symbol of the one at least one code word of the described information corresponding to the first kind and at least one code word of the described information corresponding to the second kind has ultimate range.That is,, in planisphere, these two code words are separated as much as possible in described figure.For instance, in Fig. 1, symbol 10 and 01 has ultimate range, and same, symbol 11 and 00 also separates to the full extent.In addition, according to the method, code word comprises same channel and different modulation symbols.And for described at least one feedback information message, at least one in S symbol be not for comprising any code word of described same channel.
In the method, ultimate range can be the Euclidean distance in signal space, as previously demonstrated in conjunction with Fig. 1.Term " ultimate range " meaning is in the context of the present invention: select two modulation symbols, make for available symbols set, the probability that another one detected mistakenly during one in sending described modulation symbol reduces to minimum.
According to one embodiment of the method for the invention, at least one feedback information message, exist corresponding to only code word of the information of the first kind and corresponding to the only code word of the information of the second kind.This embodiment is described as to following instance.
In this first embodiment, the present invention is applicable to following situation: for HARQ-ACK field, information (for example NACK and NACK/DTX) by a code word for first kind of encoding, information (for example ACK) by a code word for second kind of encoding, described two code words comprise same channel, in this HARQ-ACK field, without other code word, use described channel.
Consider the HARQ-ACK (0) in table 2, and hypothesis has been launched code word (n
pUCCH(1), 1,0).This code word represents NACK or the NACK/DTX for HARQ-ACK (0).The code word that represents different information (being ACK) for the HARQ-ACK (0) that comprises same channel is (n
pUCCH(1), 1,0).In HARQ-ACK (0), without other code word, use channel n
pUCCH(1).If channel correctly detected, occur so NACK to ACK mistake (if (n detected
pUCCH(1), 1,0)).According to the present invention, error event mainly, owing to the detection of modulation symbol, makes it apart from increasing to maximum, make NACK to NACK error probability, reduce to minimum to ACK and ACK by the modulation symbol for these two code words is chosen as.This can see in Fig. 1, wherein corresponding to the constellation point of (b (0), b (1))=(0,1) and (b (0), b (1))=(1,0) to the full extent away from each other.In table 2, can further see the same principle of assigned modulation symbol, wherein respectively in each field (feedback information message), for for containing n
pUCCH(1) HARQ-ACK of all code words (1) and HARQ-ACK (2) maintain ultimate range.
In second embodiment of the method according to this invention, at least one feedback information message, exist corresponding to code word of the information of the first kind and corresponding to two code words of the information of the second kind.This embodiment of exemplary illustration below.
In this second embodiment, the present invention is applicable to following situation: for HARQ-ACK field, information (for example NACK and NACK/DTX) by two code words for first kind of encoding, information (for example ACK) by a code word for second kind of encoding, all code words comprise same channel, in this HARQ-ACK field, without other code word, use described channel.
For instance, in table 2, for HARQ-ACK (0), code word (n
pUCCH(2), 0,1) and (n
pUCCH(2), 0,0) represent NACK or NACK/DTX.The code word that represents different information (being ACK) for the HARQ-ACK (0) that comprises same channel is (n
pUCCH(2), 1,1).If channel correctly detected, occur so NACK to ACK mistake (if (n detected
pUCCH(2), 1,1)).According to the present invention, by being chosen as, the modulation symbol for these three code words make the distance of described modulation symbol make this error probability reduce to minimum in the maximum that increases to that represents the code word of different information at least between the two.For instance, code word (n
pUCCH(2), 0,0) with code word (n
pUCCH(2), 1,1) separate ultimate range.This can see in Fig. 1, wherein corresponding to the constellation point of (b (0), b (1))=(1,1) and (b (0), b (1))=(0,0) to the full extent away from each other.In table 2, can further see the same principle of assigned modulation symbol, wherein for any situation that exists same channel for the code word of its several times, for HARQ-ACK (1) and HARQ-ACK (2) maintain ultimate range.For NACK or NACK/DTX, this comprises respectively 2,2,0 for HARQ-ACK (0), HARQ-ACK (1) and HARQ-ACK (2).For ACK, this comprises respectively 0,0,2 for HARQ-ACK (0), HARQ-ACK (1) and HARQ-ACK (2).
In another the 3rd embodiment of the method according to this invention, for at least one feedback information message, existence is corresponding to an above code word of the information of the first kind, and corresponding to an above code word of the information of the second kind, and the number of codewords of the information of first and second kind is identical.
In this 3rd embodiment, the present invention is applicable to following situation: for HARQ-ACK field, information (for example NACK and NACK/DTX) by K>1 code word for first kind of encoding, information (for example ACK) by K code word for second kind of encoding, all code words comprise same channel, in this HARQ-ACK field, without other code word, comprise described channel.
According to the present invention, by the modulation symbol for this 2K code word is chosen as the distance that makes described modulation symbol represent the first kind information code word at least one with represent that between at least one in the code word of information of the second kind, increasing to maximum makes error probability reduce to minimum.
Arbitrary version for the method according to this invention, the information of the first kind can be any combination or the single status of Negative Acknowledgement (NACK), Negative Acknowledgement (NACK)/discontinuous transmitting (DTX), discontinuous transmitting (DTX), and the information of the second kind comprises confirmation (ACK).This information of not getting rid of first and second kind can be the information of a certain other kind, or even can have a greater variety of information, for example the information of the third class.
For any one in the version of the method according to this invention, at least one feedback information message can be fed back relevant with multiple-input and multiple-output (MIMO).
In addition, at least one feedback information message of the method according to this invention can be relevant with mixed automatic retransfer request (HARQ).
In addition, in any version of the method according to this invention, each in A channel can be corresponding to the sequences such as quasi orthogonal sequences such as using in code division multiplex.This sequence can have two-dimensional map, for example the mapping in time and frequency.Yet, other communication channel is not foreclosed.
Can in feedback information message at least both use the method according to this invention with same channel allocation.Another possibility is to have same channel allocation for all described feedback information message.
Because each code word comprises a channel and a plurality of symbol, so a plurality of feedback information message of code word codified.
The characteristic of at least one feedback information message of management by methods of the present invention, makes the feedback information to the feedback information of the first kind and the second kind, realizes the most possible correct advantage that detects described feedback information message.Yet the characteristic of at least one feedback information message is applicable to all feedback information message, thereby realize this maximum likelihood for all this type of message.Like this, sure being optimized of whole mechanism of information feedback.
Can make about feedback information message according to carrying out further encoder feedback informational message according to method of the present invention, have a pattern, described pattern comprises:
The first number code word, it comprises same channel and information-related with the first kind; The second number code word, it comprises described same channel and information-related with the second kind,
And wherein said pattern is applicable to all feedback information message.That is to say, if (for example), for a feedback information message, (existence comprises same channel and two code words relevant with NACK, the first number is two), and for described same feedback information message, existence comprises described same channel and a code word (that is, second number be) relevant with ACK.Then, for all other feedback information message, repeat this pattern of 2+1 code word.Yet, can be different between feedback information message for the channel of code word that other feedback information message is encoded, but it is identical in same feedback information message.
Consider (for example) table 2: the NACK/ACK row (feedback information message) for for HARQ-ACK (0), exist two to comprise same channel and the code word relevant with the information (NACK, NACK/DTX) of the first kind: (n
pUCCH(2), 0,1) and (n
pUCCH(2), 0,0).In addition, for same feedback information message, exist one to comprise described same channel (n
pUCCH(2)) and the code word relevant with the information (ACK) of the second kind: (n
pUCCH(2), 1,1).Now, consider other two feedback information message, can recognize this same pattern.For HARQ-ACK (1): two code words are for NACK, NACK/DTX:(n
pUCCH(2), 0,1) and (n
pUCCH(2), 0,0), a code word is for ACK:(n
pUCCH(2), 1,1).For HARQ-ACK (2): two code words are for NACK, NACK/DTX:(n
pUCCH(0), 1,1) and (n
pUCCH(0), 0,1), a code word is for ACK:(n
pUCCH(0), 1,0).Therefore, for all three feedback information message, repeat same pattern.Note, channel only must be identical in same feedback information message, and need not be identical between a plurality of feedback information message.For the first two feedback information message of this example, channel is n
pUCCH, and for last feedback information message, channel is n (2)
pUCCH(0).Therefore, this is the 2+1 schema instance from table 2.Equally, 1+1 and 1+2 schema instance can be shown as and be present in table 2.Equally, for example, in table 14, in all feedback information message, there is 1+1 pattern.
The number of the feedback information message of the method according to this invention can (for example) be any one in following numeral: 2,3 or 4.If have enough modulation symbols to can be used for coded message, also can have more message.
In the method according to the invention, the number S of modulation symbol can (for example) be four.Using an example of this modulation of four symbols is the Quadrature Phase Shift Keying (QPSK) through Gray code.Yet, in described method, do not exist using the inherent limitations of other modulation, so the number of modulation symbol can not be four.For instance, can use 8 phase shift keyings that utilize eight symbols.
The method according to this invention is also not limited to any specific mobile radio communicaltions system, can be by described method for example, for using any mobile radio communicaltions system (Long Term Evolution (LTE) AS) of carrier aggregation.
A in a method according to this invention channel can be that (for example) special user equipment (UE) is reserved: the combination of implicit reservation, explicit signaling or implicit reservation and explicit signaling by any one in the following.Implicit reservation will mean that subscriber equipment observes the behavior of wireless base station, and calculates and use which channel based on pre-defined rule.For instance, based on wireless base station, determine on which channel, to send a certain other message, UE can be used described information to decide should be by which channel for code word according to the present invention.For instance, can be implicitly relevant with unique channel for launching the running time-frequency resource of the downlink control channel being associated.Explicit signaling will relate to explicit message indicates and uses which channel.For instance, when implicit reservation cannot provide the different channels of q.s, or in communicating by letter between UE and base station, do not exist enough implicit expression to transmit about when using the average information of which channel, implicit expression and explicit reserved combination are by useful.In said case, can supplement remaining information with explicit signaling.
If need further flexibility, the method according to this invention can comprise by higher level signaling and configures described feedback information message.Like this, feedback information message configuration can according to circumstances change, and still keeps according to the present invention and the characteristic of appointment simultaneously.For instance, can be according to the number of the Serving cell being configured and the downlink transmission pattern of each Serving cell and configure the number of feedback information message.
Should point out, for the method according to this invention, described codeword set can form the subset of larger codeword set.That is, can have larger code book, it needn't have the characteristic according to codeword set of the present invention, but the subset of code words that larger code book comprises has described characteristic really.May be by this subset of larger code book described in taking out compared with the subset of code words of large code book described in only using.
Also has probable to aware: the method according to this invention can for example, be used in conjunction with a plurality of antenna ports of () subscriber equipment.; if it is said and form the first code book by the number of the feedback information message of codeword coding; and at least one the extra code book that has the characteristic with the first code book, each in the first code book and at least one extra code book can be assigned to corresponding antenna port so.This is also at touch upon above.
It must be emphasized that, all changes form and the embodiment of the method according to this invention mentioned above are all capable of being combined, only otherwise have the intrinsic contradictions for this combination.For instance, combine basic skills of the present invention, the number that makes modulation symbol be four and channel in each corresponding to a sequence, be completely possible, so this forms effectively combination.On the contrary, combine basic skills of the present invention, make:
-for described at least one feedback information message, there is the only code word corresponding to the information of the first kind, and corresponding to the only code word of the information of the second kind,
Make simultaneously:
-for described at least one feedback information message, existence is corresponding to a code word of the information of the first kind, and corresponding to two code words of the information of the second kind, this combination is invalid, because consider that a plurality of code words comprise same channel, above-mentioned two is contradiction.
All effective combinations are all regarded as disclosing in the preceding article.
For exemplary illustration performance of the present invention, the Numerical evaluation of the detection performance of the code book that Fig. 2 contains use table 1.Table 3 displaying is not applied according to the code book of the distribution of modulation symbol of the present invention example.Fig. 3 displaying, while using this exemplary code book, performance is very different.
Table 3. is for the example code book of the HARQ-ACK with 3 bit multiplexeds.
| Entry number | HARQ-ACK(0)、HARQ-ACK(1)、HARQ-ACK(2) | n PUCCH | b(0),b(1) |
| 1 | ACK、ACK、ACK | n PUCCH(2) | 1,1 |
| 2 | ACK、ACK、NACK/DTX | n PUCCH(0) | 1,1 |
| 3 | ACK、NACK、ACK | n PUCCH(0) | 1,0 |
| 4 | ACK、NACK、NACK/DTX | n PUCCH(1) | 1,1 |
| 5 | NACK、ACK、ACK | n PUCCH(1) | 0,1 |
| 6 | NACK、ACK、NACK/DTX | n PUCCH(0) | 0,0 |
| 7 | NACK/DTX、NACK/DTX、ACK | n PUCCH(2) | 0,1 |
| 8 | NACK/DTX、NACK/DTX、NACK/DTX | n PUCCH(2) | 1,0 |
| 9 | DTX、DTX、DTX | N/A | N/A |
In table 2, for each HARQ-ACK field, in two code words, use a channel, and in two code words, use two channels.For instance, for HARQ-ACK (0), when information is NACK or NACK/DTX, n
pUCCH(2) for two code words, and n
