Description

Processing method and device that correct/error response message sends
Technical field
The present invention relates to the communications field, in particular to a kind of processing method and device of correct/error response message transmission.
Background technology
Mixing in automatic request retransmission (Hybrid Automatic Repeat Request the abbreviates HARQ as) mode, the code word of making a start and sending not only can error detection, but also has certain error correcting capability.After the receiving terminal decoder is received code word, at first check error situation, if in the error correcting capability of code word, then carry out error correction automatically, if wrong a lot, surpassed the error correcting capability of code word, come out but can detect mistake, then receiving terminal is given the decision signal of making a start by feedback channel, requires to make a start retransmission of information.At OFDM (Orthogonal Frequency Division Multiplex, abbreviate OFDM as) in the system, reply (Acknowledged/Non-acknowledged by correct/error, abbreviating ACK/NACK as) message represents to transmit correct/error, need to judge whether to retransmit with this.
At Long Term Evolution (Long Term Evolution, abbreviate LTE as) in the system, the ACK/NACK response message can be gone control channel (Physical UplinkControl Channel physically, abbreviate PUCCH as) upward send separately, the shared channel (Phyasical Uplink Shared Channel abbreviates PUSCH as) of also can going is physically gone up and is sent with data.
At Frequency Division Duplexing (FDD) (Frequency Division Duplex, abbreviate FDD as) in the system, because ascending-descending subframes is one to one, so as Physical Downlink Shared Channel (PhyasicalDownlink Shared Channel, abbreviate PDSCH as) when only comprising a streams of code words, terminal (User Equipment, abbreviate UE as) to feed back the ACK/NACK response message of 1 bit, when PDSCH comprises two streams of code words, UE will feed back the ACK/NACK response message of 2 bits, when UE when current subframe does not have PUSCH to send, UE will adopt form 1a/1b to send the ACK/NACK response message of this 1/2 bit on PUCCH; And when UE when current subframe has PUSCH to send, then UE is this 1/2 bit information, through of the mapping of certain ACK/NACK state to corresponding bits, after chnnel coding, scrambling, the modulation with data multiplex together, on PUSCH, send then.
At time division duplex (Time Division Duplex, abbreviate TDD as) in the system, because ascending-descending subframes is not one to one, the ACK/NACK response message that is a plurality of descending sub frame correspondences need send on the PUCCH/PUSCH of sub-frame of uplink channel, and wherein binding window (bundling window) has been formed in the set of the descending sub frame of sub-frame of uplink correspondence.In LTE TDD, defined the transmission of two kinds of ACK/NACK response messages.Below this is described respectively.
A kind of is ACK/NACK binding (ACK/NACK bundling) method, the basic thought of this method is to carry out logic and operation in the ACK/NACK message of the streams of code words of each descending sub frame correspondence of this sub-frame of uplink feedback, if when the PDSCH of descending sub frame transmission comprises 2 streams of code words, UE will feed back the ACK/NACK response message corresponding to 2 bits of each streams of code words of having passed through the operation of subframe logical AND, if the PDSCH of each subframe transmission all has only a streams of code words, UE will feed back the ACK/NACK response message corresponding to 1 bit of this streams of code words of having passed through the operation of subframe logical AND, when UE when current subframe does not have PUSCH to send, UE will adopt form 1a/1b to send the ACK/NACK response message of this 1/2 bit on PUCCH; And when UE when current subframe has PUSCH to send, then UE, sends this 1/2 bit information then through certain chnnel coding, channel interleaving and data multiplex together on PUSCH.
Another kind is ACK/NACK multiplexing (ACK/NACK multiplexing) method, this method need be ACK/NACK response message of each descending sub frame feedback, a plurality of subframes then need to feed back a plurality of ACK/NACK response messages, and when the PDSCH of certain descending sub frame transmission comprises 2 streams of code words, earlier the ACK/NACK response message of each streams of code words is carried out the logical AND operation, finally the only corresponding ACK/NACK response message of each descending sub frame.When UE when current subframe does not have PUSCH to send, UE will adopt form 1b combined channel to select the mode of (format 1b with channel selection) to send this a plurality of ACK/NACK response messages on PUCCH, and the core concept of this method is exactly to utilize on different PUCCH and this channel different modulation symbols to represent different ACK/NACK response messages.This method makes portable ACK/NACK response message can reach 4 bits at most by the mode of channel selection in conjunction with control channel form 1b.
It still is that ACK/NACK mulitplexing comes feeding back ACK/NACK to be disposed by high level that UE adopts ACK/NACK bundling.
In order to satisfy (the International TelecommunicationUnion-Advanced of senior International Telecommunications Union, abbreviate ITU-Advanced as) requirement, senior Long Term Evolution (Long Term Evolution Advanced as the evolution standard of LTE, abbreviating LTE-A as) system need support bigger system bandwidth (reaching as high as 100MHz), and need the existing standard of backward compatibility LTE.On the basis of prior LTE system, the bandwidth of LTE system can be merged and obtain bigger bandwidth, this technology is called carrier aggregation (Carrier Aggregation, abbreviate CA as) technology, the availability of frequency spectrum, alleviation frequency spectrum resource that this technology can improve the IMT-Advance system are in short supply, and then optimize the utilization of frequency spectrum resource.
When LTE-A had adopted carrier aggregation technology, when the base station is UE when having disposed a plurality of downlink component carrier, UE need feed back the ACK/NACK response message of these a plurality of downlink component carrier corresponding codewords streams.In LTE-A, when on the ACK/NACK response message is gone control channel physically, sending, defined two kinds of feedback systems: adopt PUCCH form 1b (format 1b) combined channel to select (Format 1b with channel selection), and based on a kind of feedback system of DFT-s-OFDM.
In correlation technique, though stipulated to adopt PUCCH format 1b to feed back, but do not disclose concrete feedback method, promptly in correlation technique, pointed out a kind of idea that can adopt PUCCH format 1b to feed back, and specific implementation not.In addition, in correlation technique, when the mode that adopts PUCCH format 1b combined channel to select was fed back, current still do not have solution for its corresponding mapping table design yet.

The assembled state of the M that UE need feed back an ACK/NACK response message can be expressed as HARQ_ACK (0), HARQ_ACK (1) ..., HARQ_ACK (M-1) }; PUCCH form 1b goes up the dibit information that sends and is designated as b (0) b (1).
Terminal sent the method for correct and wrong answer when the correct and wrong answer that following examples provide fed back when the mode that adopts Physical Uplink Control Channel (PUCCH) form 1b combined channel to select, and was applicable to the system that has adopted carrier aggregation.
Fig. 1 is that as shown in Figure 1, this flow process comprises the steps: according to the flow chart of the processing method of the ACK/NACK response message transmission of the embodiment of the invention
Step S102, UE is according to the carrier transmission pattern of carrier aggregation configuration information and configuration, detect the PDSCH that configuration flows for its each downlink component carrier corresponding codewords, obtain the ACK/NACK response message HARQ_ACK (i) on each downlink component corresponding codewords stream;
Step S104, UE according to the assembled state of M ACK/NACK response message HARQ_ACK (0), HARQ_ACK (1) ..., HARQ_ACK (M-1) }, select an available PUCCH channel Adopt PUCCH form 1b to send 2 bit information b (0) b (1), wherein, this available PUCCH channel is

I=0,1 ..., M-1.Be the default mapping relations of UE basis, be identified for sending the Physical Downlink Control Channel PUCCH channel indexes of Physical Uplink Control Channel PUCCH form 1b
Figure BSA00000298617600083
And information b (0) b (1) of 2 bits that carry on the PUCCH form 1b (for example, b (0) b (1) be following four kinds the combination one of: 00,01,10,11).
Preferably, when implementing, can be according to the following default mapping relations of determining one of at least:
Terminal is determined is used to send the PUCCH of PUCCH form 1b Be that terminal can obtain or by obtaining according to the Physical Downlink Control Channel that correctly receives and the implication relation between the Physical Uplink Control Channel index by signaling method.Here, the state of correct/error response message of downlink component carrier that this can be used to send the PUCCH correspondence of PUCCH form 1b is called right and wrong DTX state
When terminal only detects main downlink component carrier or sub-district, terminal will adopt PUCCH form 1a or 1b in the PUCCH of main downlink component carrier or sub-district correspondence feeding back ACK/NACK response message;
When the pairing constellation point of the information b of 2 bits (0) b (1) was adjacent, its corresponding correct and wrong answer had only one to be different.
Preferably, these mapping relations are that terminal and base station both sides make an appointment.
Preferably, these mapping relations can be relevant with the M value, the mapping table that different M values is corresponding different.
Preferably, can determine one of at least combinations of states according to following:
When HARQ-ACK (0), HARQ-ACK (1) ..., HARQ-ACK (M-1) } in the number of correct ACK be that N (during 0＜N＜=M), does not then distinguish the wrong NACK and the DTX state of other ACK/NACK response messages;
As { HARQ-ACK (0), HARQ-ACK (1), ..., HARQ-ACK (M-1) } in the number of ACK be 0 o'clock, if terminal correctly detects PDCCH on main downlink component carrier, and its corresponding PDSCH detects mistake, need be fed back to NACK, then terminal is fed back { HARQ-ACK (0), HARQ-ACK (1) accordingly on the PUCCH of the PDCCH of main downlink component carrier correspondence, ..., HARQ-ACK (M-1) }; If terminal does not correctly detect PDCCH on main downlink component carrier, then terminal does not send any signal to the base station;
Need the downlink component carrier of 2 correct and wrong answers of feedback when being terminal configuration, and the detected PDSCH of current subframe is when being transmitted as a streams of code words, then the corresponding correct and wrong answer of PDSCH transmission is mapped to first HARQ_ACK among 2 HARQ_ACK corresponding with this downlink component carrier, and another HARQ_ACK of this downlink component carrier correspondence is set to DTX or NACK.
For example, be 2 for the downlink component carrier of terminal configuration or sub-district, and the transmission mode of two downlink component carriers or sub-district need be fed back under the situation of 1 correct and wrong answer, correct and wrong answer corresponding HARQ instance _ the ACK (0) of main downlink component carrier or sub-district, the correct and wrong answer corresponding HARQ instance _ ACK (1) of auxilliary downlink component carrier (or sub-district); When being 2 for the downlink component carrier of terminal configuration or sub-district, and the transmission mode of one of them downlink component carrier or sub-district need be fed back 2 correct and wrong answers, when the transmission mode of another downlink component carrier (or sub-district) need be fed back 1 correct and wrong answer, 2 correct and wrong answers of downlink component carrier that then need to feed back 2 correct and wrong answers are corresponding with HARQ_ACK (0) and HARQ_ACK (1), need the correct and wrong answer of downlink component carrier of 1 correct and wrong answer of feedback corresponding with HARQ_ACK (2); When the transmission mode that for the downlink component carrier of terminal configuration or sub-district is 2 and two component carriers or sub-district need be fed back 2 correct and wrong answers, 2 correct and wrong answer corresponding HARQ instance _ ACK (0) of main downlink component carrier or sub-district and HARQ_ACK (1), 2 the correct and wrong answer corresponding HARQ instance _ ACK (2) and the HARQ_ACK (3) of auxilliary downlink component carrier or sub-district.
Below above-mentioned mapping relations and the satisfied design principle of combinations of states are described.Need to prove that following principle can independent assortment, also can all observe.Below design principle is described respectively.
Principle 1: as { HARQ-ACK (0), HARQ-ACK (1), ..., HARQ-ACK (M-1) } in the number of ACK be that N is (during 0＜N＜M), then not distinguishing all the other (M-N) individual correct and wrong answers is that NACK still is the DTX state, that is the NACK and the DTX state that, merge other ACK/NACK response messages.
Principle 2: as { HARQ-ACK (0), HARQ-ACK (1), ..., HARQ-ACK (M-1) } in the number of ACK be 0 o'clock, if terminal correctly detects PDCCH on main downlink component carrier, and its corresponding PDSCHs detects wrong (being fed back to NACK), then terminal is fed back corresponding { HARQ-ACK (0) on the PUCCH channel of the PDCCH of principal component carrier wave correspondence, HARQ-ACK (1) ..., HARQ-ACK (M-1) }; If terminal does not correctly detect PDCCH on the principal component carrier wave, then terminal does not send any signal to the base station.
Principle 3: when the downlink component carrier (or sub-district) of configuration is that the transmission mode of 2 and two component carriers (or sub-district) is need feed back 1 correct and wrong answer the time, correct and wrong answer corresponding HARQ instance-the ACK (0) of main downlink component carrier (or sub-district), the correct and wrong answer corresponding HARQ instance-ACK (1) of auxilliary downlink component carrier (or sub-district); When the downlink component carrier (or sub-district) of configuration be 2 and the transmission mode of one of them component carrier (or sub-district) need feed back 2 correct and wrong answers, when the transmission mode of another component carrier (or sub-district) need be fed back 1 correct and wrong answer, 2 correct and wrong answers of component carrier that then need to feed back 2 correct and wrong answers are corresponding with HARQ-ACK (0) and HARQ-ACK (1), need the correct and wrong answer of component carrier of 1 correct and wrong answer of feedback corresponding with HARQ-ACK (2); When the downlink component carrier (or sub-district) of configuration is that the transmission mode of 2 and two component carriers (or sub-district) is need feed back 2 correct and wrong answers the time, 2 correct and wrong answer corresponding HARQ instance-ACK (0) of main downlink component carrier (or sub-district) and HARQ-ACK (1), 2 the correct and wrong answer corresponding HARQ instance-ACK (2) and the HARQ-ACK (3) of auxilliary downlink component carrier (or sub-district).
Principle 4: when terminal only detects main downlink component carrier, then terminal will adopt PUCCH form 1a or 1b in the corresponding PUCCH channel feedback of main downlink component carrier (or sub-district).
Principle 5: for having disposed the downlink component carrier that needs 2 correct and wrong answers of feedback, if current subframe only detects corresponding PDSCH transmission on a streams of code words, then the corresponding correct and wrong answer of this PDSCH transmission is mapped to first HARQ-ACK among 2 HARQ-ACK corresponding with this component carrier, and another HARQ-ACK of this component carrier correspondence is set to NACK or DTX.
Principle 6:(b0, when b1) pairing constellation point was adjacent, its corresponding correct and wrong answer had only one to be different.
Go out outside the above-mentioned Several principles, a principle of also following is: available PUCCH channel is that UE can obtain, promptly can obtain or obtain by means of signaling according to implicit between Physical Downlink Control Channel that correctly receives and the PUCCH channel indexes, the ACK/NACK response message that is to say the downlink component carrier corresponding with this PUCCH channel be non-DTX state.
Below describe obtain following default mapping relations according to above-mentioned principle by way of example.Need to prove, following (b0, first to fourth combination b1) can be any four kinds of combinations arbitrarily, and (for example, first combination can be (1,1), second combination can be (0,0), and the 3rd combination can be (1,0), the 4th combination can be (0,1), but is not limited thereto).
