Description
Technical field
The present invention relates to the communications field, particularly relate to have employed in the tdd systems of carrier aggregation technology one
Plant correct/error response (Acknowledgement/Negative Acknowledgement ACK/NACK)
The sending method of message and realize the terminal of the method.
Background technology
In mixing automatic repeat request (Hybrid Automatic Repeat Request, HARQ) mode,
Make a start the code word sent, can not only error detection, but also there is certain error correcting capability.Receiving terminal decoder
After receiving code word, first check error situation, if within the error correcting capability of code word, the most automatically entangle
Mistake, if mistake is a lot, has exceeded the error correcting capability of code word, but can detect mistake out, then receiving terminal leads to
Cross feedback channel to a decision signal of making a start, it is desirable to retransmission of information of making a start.At OFDM
In (Orthogonal Frequency Division Multiplex, OFDM) system, should by correct/error
Answer message to represent transmitting correct/error, judge whether to need to retransmit with this.
At Long Term Evolution (Long Term Evolution, LTE, its corresponding standard agreement is Rel-8/9)
In system, ACK/NACK response message can be gone physically and be controlled channel (Physical Uplink Control
Channel, PUCCH) upper individually transmission, it is also possible to row shares channel (Physical Uplink physically
Shared Channel, PUSCH) on send together with data.
In FDD (Frequency Division Duplex, FDD) system, due to ascending-descending subframes
One to one, thus when Physical Downlink Shared Channel (Physical Downlink Shared Channel,
When PDSCH) only comprising a streams of code words, UE to feed back the ACK/NACK response message of 1 bit, when
When PDSCH comprises two streams of code words, UE to feed back the ACK/NACK response message of 2 bits, works as UE
When present sub-frame does not has PUSCH to be sent, UE will use form 1a/1b to send on PUCCH
The ACK/NACK response message of this 1 or 2 bit；And when UE has PUSCH to send at present sub-frame,
Then UE is by this 1 or 2 bit information, through the mapping of certain ACK/NACK state to corresponding bits,
Chnnel coding, scramble, modulate after together with data-reusing, then on PUSCH send.
In time division duplex (Time Division Duplex, TDD) system, owing to ascending-descending subframes is not
One to one, say, that the ACK/NACK response message that multiple descending sub frames are corresponding needs at one
Sending on the PUCCH/PUSCH channel of sub-frame of uplink, the descending sub frame collection that wherein sub-frame of uplink is corresponding is charge-coupled
Become binding window (bundling window).In LTE TDD, define two kinds of ACK/NACK
Response message feedback pattern: one is that ACK/NACK binds (ACK/NACK bundling), such as Fig. 1
Shown in, the basic thought of this feedback model is each descending sub frame fed back at this sub-frame of uplink will to be needed corresponding
The ACK/NACK message of streams of code words carry out logic and operation, if the PDSCH of a descending sub frame sends out
Penetrate when comprising 2 streams of code words, UE to feed back have passed through the operation of subframe logical AND corresponding to each streams of code words
The ACK/NACK response message of 2 bits, if the PDSCH of each subframe launches only one of which code words
Stream, UE to feed back the ACK/NACK of 1 bit corresponding to this streams of code words that have passed through the operation of subframe logical AND
Response message, when UE does not has PUSCH to be sent at present sub-frame, UE will use on PUCCH
Form 1a/1b sends the ACK/NACK response message of this 1 or 2 bit；And when UE is at present sub-frame
When having PUSCH to send, then UE is by this 1 or 2 bit information, hands over through certain chnnel coding, channel
Knit together with data-reusing, then send on PUSCH.Another kind is ACK/NACK multiplexing
(ACK/NACK multiplexing) feedback model, as in figure 2 it is shown, this feedback model needs under each
Row subframe one ACK/NACK response message of feedback, multiple subframes then need to feed back multiple ACK/NACK
Response message, and when the PDSCH of certain descending sub frame launches and comprises 2 streams of code words, first to each code word
The ACK/NACK response message of stream carries out logical AND operation, the most corresponding one of final each descending sub frame
ACK/NACK response message.When UE does not has PUSCH to be sent at present sub-frame, UE will be
The upper mode using form 1b combined channel to select (format 1b with channel selection) of PUCCH
Sending this multiple ACK/NACK response message, the core concept of the method utilizes different
On PUCCH channel and this channel, different modulation symbols represents different ACK/NACK response message.
The method is combined by Channel assignment and controls by the way of channel format 1b, the portable ACK/NACK made
Response message is at most up to 4 bits.When LTE defines different ascending-descending subframes configuration, namely up-downgoing
The combinations of states of ACK/NACK response message and selection when sub-frame configuration is respectively 1: 2/3/4 (M=2/3/4)
PUCCH channel and this channel on mapping relations table (letter between 2 bit information b (0) b (1) that carry
Claiming mapping table, for distinguishing with the mapping table of LTE-A described later, mapping table here is referred to as LTE
Mapping table)
UE uses ACK/NACK bundling or ACK/NACK multiplexing to feed back
ACK/NACK is configured by high level.Discussion below sends on PUCCH just for ACK/NACK.
In order to meet senior International Telecommunication Union (International Telecommunication
Union-Advanced, ITU-Advanced) requirement, the senior of evolution standard as LTE is drilled for a long time
Entering (Long Term Evolution Advanced, LTE-A, the standard agreement of its correspondence is Rel-10) is
System needs to support bigger system bandwidth (reaching as high as 100MHz) and it needs to backward compatibility LTE is existing
Standard.On the basis of existing LTE system, can be combined to obtain more by the bandwidth of LTE system
Big bandwidth, this technology is referred to as carrier aggregation (Carrier Aggregation, CA) technology, this technology energy
Enough improve IMT-Advance system the availability of frequency spectrum, alleviate frequency spectrum resource in short supply, and then optimize frequency spectrum money
The utilization in source.
In the system introducing carrier aggregation, the carrier wave carrying out being polymerized is referred to as component carrier (Component
Carrier, CC), also referred to as one Serving cell (Serving Cell).It is also proposed that principal component carries
Ripple/community (Primary Component Carrier/Cell, PCC/PCell) and auxiliary component carrier/community
The concept of (Secondary Component Carrier/Cell, SCC/SCell), is carrying out carrier aggregation
In system, including at least a main Serving cell and auxiliary serving cell, the most main Serving cell is constantly in sharp
The state of living.
When LTE-A have employed carrier aggregation technology, when base station is that UE is configured with multiple downstream service community
Time, UE needs to feed back the ACK/NACK response message of this multiple downstream service communities corresponding codewords stream.?
In LTE-A, when ACK/NACK response message row physically controls to send on channel, define two
Plant feedback system: use PUCCH format 1b combined channel to select (Format 1b with channel
And feedback system based on DFT-s-OFDM selection).Due to feedback based on DFT-s-OFDM
Its channel architecture of mode is the most different from PUCCH format 1/1a/1b/2/2a/2b, thus assists at existing LTE-A
In view, this structure is referred to as PUCCH format 3 (PUCCH format 3).For being configured with multiple clothes
The UE of business community, if the ACK/NACK that described UE at most can only support 4 bits feeds back, then
Mode feeding back ACK/NACK that described UE will use PUCCH format 1b combined channel to select；If
If described UE can support to feed back more than the ACK/NACK of 4 bits, then base station will further be passed through
It is the mode or employing using PUCCH format 1b combined channel to select that high-level signaling configures described UE
PUCCH format 3 carrys out feeding back ACK/NACK.
The mode selected for the PUCCH format 1b combined channel in LTE-A, current agreement is respectively
TDD system and FDD system define different mapping tables, and are all different from the mapping table of LTE, respectively
As shown in Fig. 3～Fig. 9, wherein Fig. 3～Fig. 5 is the mapping table (corresponding respectively to M=2,3,4) of LTE,
Fig. 6～Fig. 8 is that (corresponding respectively to A=2,3,4, A is LTE-A FDD for the mapping table of LTE-A FDD system
In carrier aggregation system, it is allocated to the sum of the transmission block of the Serving cell of UE), Fig. 9 is LTE-A TDD
The mapping table of system.
In FDD system, when UE is configured to use the mode of PUCCH format 3 to feed back
During ACK/NACK, owing to sending the channel resource that used of PUCCH format 3 according on Scell
ACK/NACK resource indicator (ACK/NACK Resource Indicator, ARI) dynamically indicates UE
Use 4 of high-rise configuration or 4 in (when that PUCCH format 3 have employed transmitting diversity) which
Individual/right, therefore, when UE only receives the PDSCH of Pcell, the channel resource of PUCCH format 3 is
Cannot obtain, at this time, agreement specifies, employing PUCCH format 1a/1b is fed back it by UE
ACK/NACK.And when UE uses the mode of PUCCH format 1b combined channel selection to feed back
During ACK/NACK, if owing to the mapping table of its Channel assignment just already has accounted for only receiving design when
To main Serving cell, its form such as PUCCH format 1a/1b sent.Therefore, for using PUCCH
For the UE of mode feeding back ACK/NACK that format 1b combined channel selects, its ACK/NACK is anti-
Feedback mode always uses PUCCH format 1b combined channel to select, and without to receiving only PCell's
The situation of PDSCH does special handling.
In a tdd system, when UE is only configured with a Serving cell (identical with LTE Rel-8/9),
Base station needs further to indicate UE to be to use ACK/NACK bundling or adopt by high-level signaling
Feeding back ACK/NACK is carried out by the mode of ACK/NACK multiplexing.When UE is configured with multiple service
During community, UE is selected by employing PUCCH format 1b combined channel or PUCCH format 3 feeds back
ACK/NACK.When being configured with multiple Serving cell and using PUCCH format 3 to feed back
The UE of ACK/NACK, when it receives only the PDSCH of Pcell, how feeding back ACK/NACK
It it is a problem demanding prompt solution.
Furthermore, it is contemplated that LTE-A up in introduce multiple antennas, PUCCH uses orthogonal space money
Diversity (Spatial Orthogonal Resource Transmit Diversity, SORTD) is launched as it in source
Penetrating diversity scheme, specify simultaneously, whether different PUCCH format use transmitting diversity to be separate configurations,
That is the emission diversity scheme of PUCCH format 1a/1b and PUCCH format 3 can be different
's.Therefore, when emission diversity scheme and the transmitting of PUCCH format 1a/1b of PUCCH format 3
When scheme is inconsistent, when PDSCH and UE receiving only Pcell will use PUCCH format 1a/1b
During feedback, UE use which kind of multi-antenna transmission scheme come feeding back ACK/NACK be also one urgently to be resolved hurrily
Problem.
