Description
Technical field
The present invention relates to the communications field, in particular to a kind of mixed automatic retransfer response message (HARQ
Acknowledgement, referred to as HARQ-ACK) feedback method for treating and system.
Background technology
In hybrid automatic request retransmits (Hybrid Automatic Repeat Request, referred to as HARQ) mode,
Transmitting terminal send code word can not only error detection, also with certain error correcting capability.The decoder of receiving terminal receive code word it
Afterwards, error situation is examined first, it is automatic to carry out error correction if it is within the error correcting capability of code word；If wrong a lot, surpass
The error correcting capability of code word has been crossed, but has remained to detection mistake and has been come out, then receiving terminal sends one to transmitting terminal by feedback channel and sentenced
Certainly signal, it is desirable to transmitting terminal retransmission of information.In OFDM (Orthogonal Frequency Division
Multiplex, referred to as OFDM) in system, pass through HARQ response messages (HARQ Acknowledgement, referred to as HARQ-
ACK) fed back to base station, judge whether to need to retransmit with this, when the HARQ-ACK response messages for feeding back to base station are ACK
When, represent that receiving terminal proper reception of information；When the HARQ-ACK response messages for feeding back to base station are NACK, then it represents that receive
End receives mistake, it is necessary to which base station is retransmitted.
Long Term Evolution (Long Term Evolution, referred to as LTE, the standard agreement corresponding to it are Rel-8/9)
In system, HARQ-ACK response messages can physically row control channel (Phyasical Uplink Control
Channel, referred to as PUCCH) on individually send, can also physically row shared channel (Phyasical Uplink
Shared Channel, referred to as PUSCH) on sent together with data.
In time division duplex (Time Division Duplex, referred to as TDD) system, because ascending-descending subframes are not one
One is corresponding, that is to say, that the corresponding ACK/NACK response messages of multiple descending sub frames are needed in sub-frame of uplink
Sent on PUCCH/PUSCH channels, the wherein corresponding descending sub frame set of sub-frame of uplink constitutes binding window (bundling
window).In LTE TDD, two kinds of HARQ-ACK feedback models are defined：One kind is HARQ-ACK bindings (HARQ-ACK
Bundling), as shown in figure 1, the basic thought of the feedback model is will to need each descending son in sub-frame of uplink feedback
The HARQ-ACK message of the corresponding streams of code words of frame carries out logic and operation, if the PDSCH transmittings of a descending sub frame include 2
During streams of code words, user equipment (User Equipment, referred to as UE), which will feed back, have passed through corresponding to for subframe logical AND operation
The HARQ-ACK response messages of 2 bits of each streams of code words, if PDSCH transmittings all only one of which streams of code words of each subframe,
Then UE will feed back the HARQ-ACK response messages for 1 bit corresponding to the streams of code words that have passed through the operation of subframe logical AND, work as UE
When present sub-frame does not have PUSCH to send, UE will send the HARQ- of this 1/2 bit on PUCCH using form 1a/1b
ACK response messages；And when UE has PUSCH transmissions in present sub-frame, then UE is by this 1/2 bit information, by certain channel
Then coding, channel interleaving send together with data-reusing on PUSCH.Another is HARQ-ACK multiplexings (HARQ-ACK
Multiplexing) feedback model, as shown in Fig. 2 the feedback model needs to feed back a HARQ-ACK for each descending sub frame
Response message, multiple subframes then need to feed back multiple HARQ-ACK response messages, and when the PDSCH transmittings of certain descending sub frame are included
During 2 streams of code words, first the HARQ-ACK response messages to each streams of code words carry out logical AND operation, and final each descending sub frame is only
One HARQ-ACK response message of correspondence.When UE does not have PUSCH to send in present sub-frame, UE will use lattice on PUCCH
Formula 1b combined channels select the mode of (format 1b with channel selection) to send this multiple HARQ-ACK
Response message, the core concept of this method is exactly come table using modulation symbol different on different PUCCH channels and the channel
Show different HARQACK response messages.This method makes to carry by way of Channel assignment combination control channel form 1b
HARQ-ACK response messages at most up to 4 bits.When LTE defines different sub-frame configurations, that is, ascending-descending subframes configuration
When respectively 1: 2/3/4, carried in the combinations of states of ACK/NACK response messages and the PUCCH channels and the channel of selection
Mapping table (abbreviation mapping table) between 2 bit information b (0) b (1).When UE has PUSCH to send in present sub-frame,
Whether UE has corresponding PDCCH schedule informations to carry out the hair of HARQ-ACK response messages according further to current PUSCH
Send：When PUSCH has corresponding PDCCH, UE is according to the corresponding Downlink Control Information of PDCCH (Downlink Control
Information, referred to as DCI) (Downlink Assignment Indicator are referred to as inner descending distribution instruction
DAI in DAI, the DCI related to PUSCH is referred to as up DAI) information determines that HARQ-ACK response messages are sent out on PUSCH
The size of bit sequence when sending, and according to the DAI (DAI here is referred to as descending DAI) in the corresponding DCI of PDSCH come really
Position of the corresponding HARQ-ACK response messages of fixed corresponding descending sub frame among the bit sequence of feedback；When PUSCH does not have phase
During the PDCCH answered, UE is configured during determining that HARQ-ACK response messages are sent on PUSCH according to current ascending-descending subframes
The size of bit sequence, and according to the corresponding ordinal relation of sub-frame of uplink and descending sub frame to determine corresponding descending sub frame corresponding
Position of the HARQ-ACK response messages among the bit sequence of feedback；Then the HARQ-ACK bits these needs fed back
Sequence carries out channel coding, and channel interleaving is finally sent together with data-reusing on PUSCH.
Wherein, what above-mentioned up DAI was represented is to bind the interior PDSCH sent of window and for indicating semi-continuous scheduling
The PDCCH of (semi-persisitent Scheduling, referred to as SPS) release sum, and it is tired that descending DAI, which is represented,
Count the sum for the PDCCH that present sub-frame UE is detected.Up DAI and descending DAI represent with 2 bits, its corresponding ratio
It is special as shown in table 1 with corresponding meaning that is representing.
The value of the descending distribution index of table 1
TDD UE fed back using HARQ-ACK bundling or HARQ-ACK mulitplexing HARQ-ACK by
High-level signaling is configured.
In order to meet senior International Telecommunication Union (International Telecommunication Union-
Advanced, referred to as ITU-Advanced) requirement, be used as senior long term evolution (the Long Term of LTE evolution standard
Evolution Advanced, referred to as LTE-A, its corresponding standard agreement are Rel-10) system need to support bigger be
Regiment commander is wide (reaching as high as 100MHz), and needs the existing standards of backward compatibility LTE., can on the basis of existing LTE system
To be combined to the bandwidth of LTE system to obtain bigger bandwidth, this technology is referred to as carrier aggregation (Carrier
Aggregation, referred to as CA) technology, the technology can improve IMT-Advanced (International Mobile
Telecommunication, referred to as IMT-Advance) system the availability of frequency spectrum, alleviate frequency spectrum resource it is in short supply, Jin Eryou
Change the utilization of frequency spectrum resource.
In the system of carrier aggregation is introduced, the carrier wave being polymerize is referred to as component carrier (Component
Carrier, referred to as CC), also referred to as one serving cell (Serving Cell).It is also proposed that principal component carrier wave/small
Area (Primary Component Carrier/Cell, referred to as PCC/PCell) and auxiliary component carrier/cell (Secondary
Component Carrier/Cell, referred to as SCC/SCell) concept, in the system for carrying out carrier aggregation, at least wrap
Containing a main serving cell and auxiliary serving cell, wherein, main serving cell is constantly in state of activation.
When LTE-A employs carrier aggregation technology, if base station is configured with multiple downstream service cells for UE, UE is needed
Feed back the HARQ-ACK response messages of this multiple downstream service cell corresponding codewords stream.In LTE-A, when HARQ-ACK responses
When message is physically sent in row control channel, two kinds of feedback systems are defined：Using PUCCH format 1b combined channels
Select (Format 1b with channel selection) and OFDM is extended based on DFT
(DFT-s-OFDM) feedback system.Due to the channel architecture and PUCCH format1/ of the feedback system based on DFT-s-OFDM
1a/1b/2/2a/2b is different, thus in existing LTE-A agreements, this structure is referred to as the (PUCCH of PUCCH format 3
format 3).When being sent in HARQ-ACK response messages physically row shared channel, UE needs are according to the polymerization of configuration
Serving cell number, the transmission mode of configuration service cell, the ratio of uplink subframe to downlink subframe (for TDD system) of configuration are determined
The HARQ-ACK bit sequences sent on PUSCH.Be configured to 1~6 for LTE-A TDD ascending-descending subframes, when UE be configured with it is many
During individual serving cell, 2bit signalings are devised in Downlink Control Information DCI format 0 and 4 as descending distribution indexWith
When UE sends HARQ-ACK on PUSCH, the size of HARQ-ACK bit sequences is determined.Value is as shown in table 2.

Situation, so that the size for the HARQ-ACK bit sequences that UE is sent is actually needed the big of feedback than base station.For example, UE matches somebody with somebody
2 serving cells have been put, and two serving cells are each configured to the downlink transfer pattern of double streams of code words, then according to correlation technique
Regulation, when UE feeds back HARQ-ACK on PUSCH, UE will need the HARQ-ACK of 4 bits of transmission, but in fact, some
Moment, eNB may only scheduled some serving cell, and now eNB only needs to the HARQ-ACK feedbacks of 2 bits, but UE is still
Fed back according to 4 bit HARQ-ACK, that is to say, that the HARQ-ACK of UE feedbacks has redundancy.Therefore, in order to more
The size of HARQ-ACK bit sequences is accurately determined, to reduce the shadow caused when HARQ-ACK is sent on PUSCH to PUSCH
Ring, the configuration for being 1 for binding window is improvedThe determination method of design and HARQ-ACK bit sequence sizes is necessary
's.
