Description

The mapping method and terminal of ACK/NACK response messages

The application be to application No. is：201010503361.X the applying date is：It is on 09 28th, 2010, entitled 《The mapping method and terminal of correct/error response message》Original application divisional application.

Technical field

The present invention relates to the communications fields, in particular to the mapping method and terminal of correct/error response message.

Background technology

In hybrid automatic request retransmits (Hybrid Automatic Repeat Request, referred to as HARQ) mode, Start send code word, can not only error detection, but also have certain error correcting capability.After receiving terminal decoder receives code word, Error situation is examined first, if within the error correcting capability of code word, it is automatic to carry out error correction, if there are many mistake, be more than The error correcting capability of code word, but mistake can be detected and come out, then receiving terminal gives originator one decision signal of hair by feedback channel, it is desirable that Originator retransmission of information.Orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplex, referred to as OFDM) in system, pass through correct/error response (Acknowledged/Non-acknowledged, referred to as ACK/NACK) Message come indicate transmission correct/error, with this to determine whether needing to retransmit.

In long term evolution (Long Term Evolution, referred to as LTE) system, ACK/NACK response messages can be with Physically individually sent in row control channel (Physical Uplink Control Channel, referred to as PUCCH), Can physically go on shared channel (Physical Uplink Shared Channel, referred to as PUSCH) with data one It rises and sends.

In frequency division duplex (Frequency Division Duplex, referred to as FDD) system, due to ascending-descending subframes One-to-one, thus when Physical Downlink Shared Channel (Physical Downlink Shared Channel, referred to as PDSCH) only include a streams of code words when, terminal (User Equipment, referred to as UE) will feed back the ACK/NACK of 1 bit Response message, when PDSCH includes two streams of code words, UE will feed back the ACK/NACK response messages of 2 bits, when UE is current When subframe does not have PUSCH to send, UE will be answered using format 1a/1b to send the ACK/NACK of this 1/2 bit on PUCCH Answer message；And when UE is when current subframe has PUSCH transmissions, then UE is by this 1/2 bit information, by certain ACK/NACK Then the mapping of state to corresponding bits is sent after channel coding, scrambling, modulation together with data-reusing on PUSCH.

In time division duplex (Time Division Duplex, referred to as TDD) system, what it is due to ascending-descending subframes is not Correspondingly, i.e., the corresponding ACK/NACK response messages of multiple downlink subframes need the PUCCH/ in a sub-frame of uplink It is sent on PUSCH channels, wherein the corresponding downlink subframe set of sub-frame of uplink constitutes binding window (bundling window).In LTE TDD, the transmission of two kinds of ACK/NACK response messages is defined.This is illustrated respectively below.

One is ACK/NACK to bind (ACK/NACK bundling) method, and the basic thought of this method is will to need The ACK/NACK message of the corresponding streams of code words of each downlink subframe of sub-frame of uplink feedback carries out logic and operation, if one When the PDSCH transmission of downlink subframe includes 2 streams of code words, UE, which will be fed back, have passed through corresponding to each for subframe logical AND operation The ACK/NACK response messages of 2 bits of streams of code words, if the PDSCH transmission of each subframe is all only there are one streams of code words, UE is wanted Feedback have passed through the ACK/NACK response messages of 1 bit corresponding to the streams of code words of subframe logical AND operation, when UE is current When subframe does not have PUSCH to send, UE will be answered using format 1a/1b to send the ACK/NACK of this 1/2 bit on PUCCH Answer message；And when UE is when current subframe has PUSCH transmissions, then UE is by this 1/2 bit information, by certain channel coding, Then channel interleaving is sent together with data-reusing on PUSCH.

Another kind is ACK/NACK multiplexing (ACK/NACK multiplexing) methods, and this method needs for each downlink Subframe feeds back an ACK/NACK response message, and multiple subframes then need to feed back multiple ACK/NACK response messages, and when under certain When the PDSCH transmission of row subframe includes 2 streams of code words, logical AND first is carried out to the ACK/NACK response messages of each streams of code words Operation, final each downlink subframe only correspond to an ACK/NACK response message.When UE does not have PUSCH to send out in current subframe When sending, UE will be on PUCCH using format 1b combined channels selection (format 1b with channel selection) Mode sends this multiple ACK/NACK response message.This method by way of channel selection combination control channel format 1b, Make portable ACK/NACK response messages at most up to 4 bits.In addition, for the ACK/NACK of different numbers, LTE TDD Define the mapping of the modulation symbol sent on the PUCCH channels and format 1b of different ACK/NACK states and selection Table.And when UE is when current subframe has PUSCH transmissions, then UE arrives multiple bit informations by certain ACK/NACK states Then the mapping of corresponding bits is sent after channel coding, channel interleaving together with data-reusing on PUSCH.UE is every A subframe needs the quantity of the ACK/NACK fed back, is configured by the ascending-descending subframes of system to determine.

UE is using ACK/NACK bundling or ACK/NACK multiplexing come feeding back ACK/NACK by high level Configuration.

In order to meet advanced International Telecommunication Union (International Telecommunication Union- Advanced, referred to as ITU-Advanced) requirement, senior long term evolution (the Long Term of the evolution standard as LTE Evolution Advanced, referred to as LTE-A) system need support bigger system bandwidth (reaching as high as 100MHz), and Need the existing standards of backward compatibility LTE.On the basis of existing LTE system, the bandwidth of LTE system can be closed And obtaining the bandwidth of bigger, this technology is known as carrier wave polymerization (Carrier Aggregation, referred to as CA) technology, should Technology can improve IMT-Advance systems the availability of frequency spectrum, alleviate frequency spectrum resource it is in short supply, and then optimize frequency spectrum resource profit With.

When LTE-A uses carrier aggregation technology, when base station is that UE is configured with multiple downlink component carriers, UE needs Feed back the ACK/NACK response messages of this multiple downlink component carrier corresponding codewords stream.In LTE-A, when ACK/NACK responses When message is physically sent in row control channel, two kinds of feedback systems are defined：Using PUCCH format 1b (format 1b) Combined channel selects (Format 1b with channel selection), and a kind of feedback side based on DFT-s-OFDM Formula.

As previously mentioned, for the method using the selection of PUCCH format 1b combined channels, for different ACK/NACK Quantity is fed back, corresponding mapping table is different, and in a mapping table, and ACK/NACK response messages put in order Difference, the channel used when UE is finally fed back and corresponding modulation symbol would also vary from.At present in the discussion of LTE-A In, the correspondence of the ACK/NACK response messages and the HARQ-ACK states in mapping table of downlink component carrier corresponding codewords stream It there is no final conclusion.

And for the method based on DFT-s-OFDM, different ACK/NACK feeds back quantity, corresponding ACK/NACK shapes The mapping of state to corresponding bits also will be different.Moreover, for the quantity of the UE ACK/NACK for needing to feed back, UE and base station are double The relationship that Fang Youyi is appointed.A working hypothesis of current LTE-A is that the ACK/NACK that UE is fed back is the downlink according to configuration The transmission mode of component carrier and each downlink component carrier determines.For example, if base station is configured with 3 to terminal Carrier wave, and three carrier waves are configured in MIMO mode, then UE needs to feed back the ACK/NACK response messages of (3x2=6) bit. But the mapping relations between 6 bit informations specifically fed back and the component carrier each configured, it there is no concrete scheme at present.

Therefore, if mapping relations or ACK/NACK responses between ACK/NACK response messages and the bit of feedback disappear Breath has different understandings, base station to come up UE feedbacks from the correspondence of the HARQ-ACK states in mapping table in base station and terminal ACK/NACK response message misinterpretations, so as to cause occur mistake.
