Description
Technical field
The present invention relates to digital communicating field, particularly relate to the terminal in a kind of large bandwidth multi-carrier system, base station and uplink control signaling transmission technology.
Background technology
The reliability of develop rapidly to data communication of digital communication system is had higher requirement, but under severe channel, especially in high data rate or high-speed mobile environment, multi-path jamming and Doppler frequency shift etc. seriously affect systematic function.Therefore, effective error-control technique, especially mixing automatic repeat request (Hybrid Automatic Repeat Request, HARQ) technology just becomes the focus endeavouring to study in the communications field.
In the descending HARQ of long evolving system (LTE:Long Term Evolution), ACK/NACK (ACK/NACK:Acknowledgement/Negative Acknowledgement) response message of Physical Downlink Shared Channel (PDSCH:Physical Downlink Shared Channel), when terminal (UE:User Equipment) does not have Physical Uplink Shared Channel (PUSCH:Physical UplinkShared Channel), be that row control channel (PUCCH:Physical Uplink ControlChannel) is upper physically to send.
In current LTE system, Physical Uplink Control Channel can support multiple upstream control signaling, comprise correct/error response message, channel condition information (CSI:Channel State Information, which includes CQI (CQI:Channel Quality Indicator), precoding matrix indicators (PMI:Precoding Matrix Indicator) and order designator (RI:Rank Indicator)), dispatch request (SR:Scheduling Request), and their combinations of simultaneously sending.
LTE defines multiple PUCCH format (format), comprise PUCCH format 1/1a/1b (its channel architecture schematic diagram as shown in Figure 1) and format 2/2a/2b (its channel architecture schematic diagram as shown in Figure 2), wherein format 1 is used for sending the dispatch request of UE, format 1a and 1b is used for the ACK/NACK response message of feedback 1 bit and the ACK/NACK response message of 2 bits respectively, format2 is used for sending descending channel condition information, format 2a is used for sending the ACK/NACK response message of CSI and 1 bit, format 2b is used for sending the ACK/NACK response message of CSI information and 2 bits.
In LTE system, in frequency division duplex system (FDD), because ascending-descending subframes is one to one, so when PDSCH only comprises a transmission block, UE will feed back the ACK/NACK response message of 1 bit, when PDSCH comprises two transmission blocks, UE will feed back the ACK/NACK response message of 2 bits.So in LTE FDD system, when UE needs to send SR and ACK/NACK response message simultaneously: (represent when sending negative SR and do not need dispatch request), UE sends 1 bit or 2 bit ACK/NACK response message in the ACK/NACK PUCCH resource distributing to it, and when sending positive SR (dispatch request is carried out in expression), UE sends 1 bit or 2 bit ACK/NACK response message in the SRPUCCH resource distributing to it; When UE needs to send ACK/NACK response message and CSI information simultaneously, if subframe is normal cyclic prefix, the ACK/NACK response message of 1 bit or 2 bits is modulated in second reference signal of each time slot, format2a/2b is adopted to send, if subframe is extended cyclic prefix, by 1 bit or 2 bit ACK/NACK response message and CSI information consolidation coding, adopt format 2 to transmit and send.
And in time division duplex (TDD) system of LTE, because ascending-descending subframes is no longer one to one, configure according to different ascending-descending subframes, a sub-frame of uplink sometimes needs the ACK/NACK response message feeding back multiple descending sub frame, multiple descending sub frames corresponding for sub-frame of uplink is called binding window (bundling window) here.In LTE, define two kinds of ACK/NACK feedback models: one is binding pattern (bundling), the core concept of the method is that the ACK/NACK response message of transmission block corresponding for each descending sub frame needing to feed back at this sub-frame of uplink is carried out logic and operation, if a descending sub frame has 2 streams of code words, UE will feed back the ACK/NACK response message of 2 bits, if each subframe only has a word stream, UE will feed back the ACK/NACK response message of 1 bit, another kind is multiplexer mode (multiplexing, namely multiplexing with channelselection, also referred to as Channel assignment), the core concept of this pattern is the different feedback states utilizing different modulation symbol on different PUCCH channels and this channel to represent the descending sub frame that needs feed back at this sub-frame of uplink, if descending sub frame there is multiple word stream, Channel assignment is carried out again after so first the ACK/NACK of multiple word stream feedbacks of descending sub frame being carried out logical AND (being also called spatial bundling), then PUCCH format 1b is used to send.That is, the 2 bit information b (0) carried by PUCCH format 1b and b (1), and the index of PUCCH channel, represent the ACK/NACK information after having carried out logical AND operation.
Therefore, in a tdd system, when ACK/NACK response message needs to send with SR or CQI simultaneously, different in its sending method and foregoing FDD system.In TDD, when ACK/NACK response message needs to send with SR or CQI simultaneously, UE is by advanced for the multiple ACK/NACK response messages in binding window row space binding, obtain the ACK/NACK response message that each descending sub frame is corresponding, then according to have passed through the binding rear number for ACK in space in binding window, obtain corresponding dibit b (0), b (1), then by PUCCH corresponding to SR by b (0), b (1) sends (when having Positive SR to send simultaneously), maybe will be modulated in second reference signal of PUCCH format 2b, or by b (0), sends on PUCCH format 2 after b (1) and CQI combined coding (below two kinds of situations send corresponding to CQI and ACK/NACK scene) simultaneously.Wherein, for the number of ACK and b (0), b (1) have default mapping relations after have passed through space binding in binding window, as shown in table 1:
Table 1: be the number of ACK and the mapping relations of b (0), b (1) after have passed through space binding in binding window
At IMT-Advanced (International MobileTelecommunications-Advanced, referred to as IMT-Advanced) in system, the high-speed transfer of data can be realized, and there is larger power system capacity, move at low speed, focus cover, the peak rate of IMT-Advanced system can reach 1Gbit/s, and when high-speed mobile, wide area cover, the peak rate of IMT-Advanced system can reach 100Mbit/s.
In order to meet senior International Telecommunication Union (International TelecommunicationUnion-Advanced, referred to as ITU-Advanced) requirement, as senior Long Term Evolution (the Long Term Evolution Advanced of the evolution standard of LTE, referred to as LTE-A) system needs to support larger system bandwidth (reaching as high as 100MHz), and needs the existing standard of backward compatibility LTE.On the basis of existing LTE system, the bandwidth of LTE system can be carried out merging and obtain larger bandwidth, this technology is called carrier aggregation (Carrier Aggregation, referred to as CA) technology, this technology can improve IMT-Advance system the availability of frequency spectrum, to alleviate frequency spectrum resource in short supply, and then optimizes the utilization of frequency spectrum resource.
After introducing carrier aggregation, current about in the discussion of downlink component carrier and PDSCH transmission block and HARQ process relation, a groundwork supposition is when not adopting space division multiplexing, a corresponding PDSCH transmission block of downlink component carrier and a HARQ process, that is, UE needs a PDSCH transmission block for each component carrier to feed back the ACK/NACK response message of 1 bit.And when adopting space division multiplexing, LTE-A current regulations, supports 2 transmission blocks at most.Therefore, when adopting space division multiplexing, UE needs 2 PDSCH transmission blocks for each downlink component carrier to feed back the ACK/NACK response message of 2 bits.
In lte-a system after have employed spectrum aggregating technology, upstream bandwidth and downlink bandwidth just can comprise multiple component carrier.When there is the PDSCH dispatched to certain UE base station on multiple downlink component carrier, and when UE does not have PUSCH to send at present sub-frame, terminal needs the ACK/NACK response message feeding back the PDSCH transmission of this multiple downlink component carrier on PUCCH.A current work supposition is these ACK/NACK response messages is sent by the upstream components carrier wave of a UE-specific; For SR information, a current work supposition is that UE only sends a SR, and this SR information is sent by the upstream components carrier wave of a UE-specific, for CSI information, a current work supposition is CSI information is sent by the upstream components carrier wave of a UE-specific.
In lte-a system, current work supposition, for SR information, UE adopts PUCCH format1 to send, for CSI, UE adopts PUCCH format 2 to send, for ACK/NACK response message, except defined PUCCH format 1a and 1b in LTE can be used in, Channel assignment (multiplexing with channel selection) outward, LTE-A adds a kind of form based on DFT-s-OFDM newly, for sending the ACK/NACK response message of more heavy load, its channel architecture schematic diagram as shown in Figure 3, for convenience of description, this structure is called PUCCH Format 3.Wherein which kind of mode UE adopts carry out feeding back ACK/NACK to be configured by high level.
In LTE-A FDD system, when being configured with UE and adopting PUCCH format 3 feeding back ACKs/NACK, if UE is when present sub-frame also will send SR simultaneously, then UE is by SR and multiple ACK/NACK response message combined coding, then sends on PUCCH format 3.And adopt Channel assignment to carry out feeding back ACK/NACK UE for being configured to, if when present sub-frame also will send SR or CSI simultaneously, if continue to use the method for TDD in LTE, as can be seen from table 1 we, as the b (0) that base station receives, during b (1)=(1,1), base station cannot judge that UE correctly receives 1 or correctly receive 4 PDSCH.Therefore, consider from the robustness point of system, base station can suppose to receive only 1, and thus, if for the scene that UE correctly have received 4 PDSCH, base station is also to retransmit, thus throughput of system hydraulic performance decline.If this method is in use to LTE-A, for FDD system, when configuration is 4 to the carrier number of UE time, the problems referred to above can exist equally.Therefore, ACK/NACK and the SR/CSI sending method simultaneously improved is needed.

Below in conjunction with drawings and the specific embodiments, technical solution of the present invention is described in further details.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combination in any mutually.
Embodiment 1
In large bandwidth multi-carrier system, when terminal needs the correct/error ACK/NACK response message of N number of Physical Downlink Shared Channel PDSCH of feedback, can transmit in the following manner, shown in this transmitting procedure Fig. 4, comprise the steps:
Step 100, the N number of ACK/NACK response message fed back as required determines that one for representing the state information of the response of configuration carrier wave;
Wherein, N is the summation of the PDSCH comprising descending assignment signalling that detects of terminal and the PDSCH that do not have descending assignment signalling, and N value is positive integer; In frequency division duplex system, 1 < N≤5, in tdd systems, 1 < N≤20.
In the present embodiment, in the following manner, N number of ACK/NACK response message can be defined as the state information that is used for the response representing configuration carrier wave:
When the ACK/NACK response message logical AND operating result of N number of PDSCH is NACK, be defined as state 1;
When the ACK/NACK response message logical AND operating result of N number of PDSCH is ACK, and carry out the ACK of logical AND operation quantity (or UE detect (or receive) to PDSCH quantity) be 1 time, be defined as state 2;
When the ACK/NACK response message logical AND operating result of N number of PDSCH is ACK, and carry out the ACK of logical AND operation quantity (or UE detect (or receive) to PDSCH quantity) be 2 time, be defined as state 3;
The like, when the ACK/NACK response message logical AND operating result of N number of PDSCH is ACK, and the quantity (or UE detects the PDSCH quantity that (or receive) arrive) of carrying out the ACK of logical AND operation for N time, be defined as N state+1.
Step 200, determined state information is mapped as 2 bit informations by the mapping relations according to setting, 2 bit informations and other ascending control informations is sent on the Physical Uplink Control Channel appointed with base station.
Wherein, after each state information being mapped as 2 corresponding bit informations, can conventionally in transmit operation, the Physical Uplink Control Channel appointed with base station sends this 2 bit information.
In preferred embodiment, when setting mapping relations, can by state 1, namely the ACK/NACK response message logical AND operating result of N number of PDSCH is NACK, is mapped as one 2 bit values.And remaining N number of state, namely the ACK/NACK response message logical AND operating result of N number of PDSCH is ACK, but the quantity (or UE detects or the PDSCH quantity that receives) of carrying out the ACK of logical AND operation is different, can according to the number of packets of ACK of carrying out logical AND operation.By the difference of carrying out the quantity of the ACK of logical AND operation be 3 one group of state information be mapped as same 2 bit values, this is because the concept of end side continuous 3 detection PDSCH failure is very little, substantially can not occur, like this, base station side receives 2 bit values, when the response status that may analyze end side configuration carrier wave according to mapping relations exists two kinds of scenes, just the scene that takes defeat for 3 times continuous in these two kinds of scenes can be got rid of, determine that end side configures the response status of carrier wave exactly.Particularly, the mapping relations between each state information and 2 bit informations can be as shown in table 2.
Table 2 is the mapping relations table of N+1 kind state and 2 bits
What the DTX in table 2 represented is, and UE is tested with PDCCH lost.
For FDD system, base station is 4 downlink component carriers to terminal configuration, namely N is 4, as shown in Figure 5, be respectively main downlink component carrier DL CC#0, auxiliary downlink component carrier DL CC#1/2/3, wherein DL CC#0/1 adopts the transmission mode of 2 streams of code words, DL CC#2/3 adopts the transmission mode of 1 streams of code words, supposes that present sub-frame scheduled DL CC#0/1/2/3 to UE simultaneously;
Assuming that UE detects DL CC#0/1/2/3 have 4 PDSCH altogether, then detect streams of code words corresponding to each PDSCH respectively, obtain corresponding ACK/NACK response message, for DL CC#0/1, owing to containing 2 streams of code words, therefore, its corresponding ACK/NACK response message is the ACK/NACK response message after have passed through spatial logic and operating, the PDSCH of each component carrier have passed through spatial logic and the ACK/NACK response message after operating is designated as HARQ-ACK (0) respectively, HARQ-ACK (1), HARQ-ACK (2), HARQ-ACK (3);
If { HARQ-ACK (0), HARQ-ACK (1), HARQ-ACK (2), HARQ-ACK (3) }={ ACK, ACK, ACK, ACK}, then the ACK/NACK response message logical AND operating result of these 4 PDSCH is ACK, the number of carrying out the ACK of logical AND operation is 4, then determine that corresponding state information is state 1, then look-up table 2, this state 1 is mapped 2 bit informations, namely b (0), b (1) are (0,1), conventionally send this b (0) afterwards, b (1) value.
Such as, present sub-frame sends b (0), need while b (1) to send SR, then UE is first by b (0), b (1)=(0, 1) 1 QPSK (quarternary phase-shift keying (QPSK) signal) symbol is modulated to, then the PUCCH channel resource that SR is corresponding is adopted, described QPSK symbol is placed in PUCCH channel corresponding to described SR for sending the symbol of data, the notation index l of each time slot of PUCCH channel structure formats 1b namely shown in Fig. 1 is 0, 1, 5, on symbol corresponding to 6, then form complete PUCCH channel to send with reference signal.
Present sub-frame sends b (0), need while b (1) to send CSI, and during present sub-frame employing conventional cyclic prefix, UE is first by b (0), b (1)=(0,1) 1 QPSK symbol is modulated to, then second reference signal being placed on each time slot in the PUCCH channel corresponding to CSI sends, on the index l of each time slot of PUCCH channel format 2b namely shown in Fig. 2 symbol corresponding to 5, then send together with CSI.
Present sub-frame sends b (0), need while b (1) to send CSI, and during present sub-frame employing extended cyclic prefix, UE is first by b (0), b (1)=(0,1) carry out combined coding with CSI, then send on the PUCCH channel format 2 corresponding to CSI.
Correspondingly, base station detects b (0), behind b (1)=(0,1), by tabling look-up 2, analyzing the PDSCH that known UE really receives is 1 or 4, but consider that the probability that UE loses 3 PDCCH is very low, and base station scheduling 4 PDSCH, therefore, base station can determine that UE correctly have received 4 PDSCH, namely correctly have received all PDSCH.
Relative to existing LTE TDD scheme, if UE feeds back b (0), b (1)=(0,1), base station side analysis may have the following two kinds scene:
The possible reception scene of scene 1-1:UE proper reception of 1 PDSCH, all the other 3 PDSCH and correctly not receive (or PDSCH demodulation makes mistakes, or PDCCH loses);
Scene 1-2:UE all correctly have received 4 PDSCH.
And for the present embodiment scheme, UE feeds back b (0), behind b (1)=(0,1), base station side analysis may have the following two kinds scene:
The possible reception scene of scene 2-1:UE proper reception of 1 PDSCH, and all the other 3 PDCCH all lost;
Scene 2-2:UE all correctly have received 4 PDSCH.
The probability of happening of scene 1-2 and scene 2-2 is equal, and for scene 2-1, its probability occurred is more much smaller than scene 1-1.Therefore, after have employed the present embodiment scheme, base station scheduling 4 PDSCH, and the UE that base station receives feeds back b (0), b (1)=(0,1), then base station can think that 4 PDSCH all receive correctly, thus without the need to retransmitting, and for existing LTE TDD scheme, then may need to retransmit, therefore, can find out, the present embodiment scheme has the gain of throughput performance relative to existing LTE TDD scheme.
Again as shown in Figure 6, assuming that present sub-frame scheduled DL CC#0/1/2 to UE.When UE detects that DL CC#0/1/2 has 3 PDSCH altogether, and respectively corresponding streams of code words is detected, obtain corresponding ACK/NACK response message.Wherein, for DL CC#0/1, owing to containing 2 streams of code words, therefore, its corresponding ACK/NACK response message is the ACK/NACK response message after have passed through spatial logic and operating, the PDSCH of each component carrier have passed through spatial logic and the ACK/NACK response message after operating is designated as HARQ-ACK (0), HARQ-ACK (1) and HARQ-ACK (2) respectively.
If { HARQ-ACK (0), HARQ-ACK (1), HARQ-ACK (2) }={ ACK, ACK, NACK}, result after logical AND operation is NACK, question blank 2 again, its corresponding states 1,2 bit information b (0) of its correspondence, b (1) is (0,0).
And for base station, it detects b (0), b (1)=(0,0) when detecting, by tabling look-up 2, know that UE does not all correctly receive all PDSCH, now, base station needs to retransmit previous scheduling.
Again Figure 7 shows that example, assuming that present sub-frame scheduled DL CC#0/1/2 to UE.When UE detects that DL CC#0/2 has 2 PDSCH altogether, respectively corresponding streams of code words is detected, obtain corresponding ACK/NACK response message.For DL CC#0, owing to containing 2 streams of code words, therefore, its corresponding ACK/NACK response message is the ACK/NACK response message after have passed through spatial logic and operating, and the PDSCH of each component carrier have passed through spatial logic and the ACK/NACK response message after operating is designated as HARQ-ACK (0) and HARQ-ACK (1) respectively.
If { HARQ-ACK (0), HARQ-ACK (1) }={ ACK, ACK}, result after logical AND operation is ACK, and the number of carrying out the ACK of logical AND operation is 2, then question blank 2, its correspondence be state 3,2 corresponding bit information b (0), b (1) is (1,0).
For this situation, because UE cannot judge whether that PDSCH lost, but base station is when detecting, detect b (0), b (1)=(1,0), by tabling look-up 2, know that UE correctly receives 2 PDSCH, and be scheduled 3 PDSCH when base station scheduling, therefore, base station knows that UE has a PDSCH lost, at this time, base station needs to retransmit previous scheduling.
Again as shown in Figure 8, in TDD system, base station is current gives terminal configuration 4 downlink component carriers, wherein DL CC#0 is main downlink component carrier, DL CC#1/2/3 is auxiliary downlink component carrier, wherein DL CC#0/1 is the transmission mode of 2 streams of code words, DL CC#2/3 is the transmission mode of 1 streams of code words, suppose to scheduled DL CC#0/1/2 to UE on subframe n simultaneously, subframe n+1 scheduled DL CC#0/1/2 to UE, subframe n+2 scheduled DL CC#0/2 to UE, subframe n+3 scheduled DL CC#0/1/3 to UE.
Suppose in TDD system, what DAI (the Downlink assignment Indicator) control domain in descending distribution represented is an order according to downlink component carrier, is accumulated to the quantity containing the PDSCH of PDCCH of having distributed of present sub-frame.
Assuming that time UE detects, subframe n detects DL CC#0/1/2 and has 3 PDSCH altogether, subframe n+1 detects DL CC#0/1/2 and has 3 PDSCH altogether, subframe n+2 detects DL CC#0/2 and has 2 PDSCH altogether, subframe n+3 detects DL CC#0/2/3 and has 3 PDSCH altogether, respectively corresponding streams of code words is detected, obtain corresponding ACK/NACK response message, the PDSCH of each component carrier have passed through spatial logic and the ACK/NACK response message after operating is designated as { HARQ-ACK (0) respectively, HARQ-ACK (1) and HARQ-ACK (2), ..., HARQ-ACK (10) }, 11 ACK/NACK response messages altogether, meanwhile, judge that PDCCH does not occur to be lost according to DAI, UE.
If these 11 ACK/NAC response messages are ACK entirely, then the result after logical AND operation is ACK, and the number of carrying out the ACK of logical AND operation is 11, table look-up 2, its correspondence be state 3,2 corresponding bit information b (0), b (1) is (1,0).
When base station is detected, detect b (0), b (1)=(1,0), by tabling look-up 2, know that the PDSCH number that UE correctly receives may be 2/5/8/11/14/17/20, and base station scheduling scheduled 11 PDSCH, therefore, base station can suppose that UE correctly have received all PDSCH, because the probability that terminal loses 3 PDCCH continuously can be ignored.
Same for the scene shown in Fig. 8, if having one in these 11 ACK/NAC response messages at least for NACK, then the result after logical AND operation is NACK, table look-up 2, its correspondence be state 1,2 corresponding bit information b (0), b (1) is (0,0).
When base station is detected, detect b (0), b (1)=(0,0), by tabling look-up 2, knowing that UE does not all correctly receive all PDSCH or there occurs PDCCH and losing, at this time, base station needs to retransmit all scheduling.
Same for the scene shown in Fig. 8, when UE detects the situation of subframe as shown in Figure 9, UE does not receive the PDSCH on subframe #n+1 on DL CC#1; The PDSCH on the undetected subframe #n+1 of UE on DL CC#1 can be judged, therefore according to DAI, UE, result after logical AND operation is NACK, and according to table 2, corresponding is state 1,2 corresponding bit information b (0), b (1) is (0,0).
Time base station is detected, detect b (0), b (1)=(0,0), by tabling look-up 2, knowing that UE does not all correctly receive all PDSCH or there occurs PDCCH and losing, at this time, base station needs to retransmit all scheduling.
Embodiment 2
The present embodiment is with in large bandwidth multi-carrier system, ACK/NACK corresponding to the main downlink component carrier needed in the ACK/NACK response message of N number of PDSCH of feedback is carried out spatial logic and operation by terminal, spatial logic and operation being carried out to the ACK/NACK corresponding to another auxiliary downlink component carrier, the ACK/NACK logical AND operating result corresponding to the ACK/NACK logical AND operating result corresponding to main downlink component carrier and described auxiliary downlink component carrier being defined as the state information of the response for representing configuration carrier wave.Particularly, state information is as follows:

| 2 | {NACK，ACK} | 0，1 |
| 3 | {ACK，NACK} | 1，0 |
| 4 | {ACK，ACK} | 1，1 |
For the scene shown in Figure 10, in FDD system, base station is current gives terminal configuration 4 downlink component carriers, wherein DL CC#0 is main downlink component carrier, DL CC#1/2/3 is auxiliary downlink component carrier, wherein DL CC#0/1 is the transmission mode of 2 streams of code words, and DL CC#2/3 is the transmission mode of 1 streams of code words, supposes that present sub-frame scheduled DL CC#0/1/2 to UE simultaneously; The wherein auxiliary downlink component carrier needing feeding back ACK/NACK appointed for base station in the present embodiment and UE both sides of DL CC#1 (SCC#1).
Assuming that detect DL CC#0/1/2 time UE detects to have 3 PDSCH altogether, respectively corresponding streams of code words is detected, obtain corresponding ACK/NACK response message, for DL CC#0/1, owing to containing 2 streams of code words, therefore, its corresponding ACK/NACK response message is the ACK/NACK response message after have passed through spatial logic and operating, the PDSCH of each component carrier have passed through spatial logic and the ACK/NACK response message after operating is designated as HARQ-ACK (0), HARQ-ACK (1) and HARQ-ACK (2) respectively.
Adopt the scheme of the present embodiment, UE only feeds back HARQ-ACK (0) corresponding to PCC and SCC#1 and HARQ-ACK (1), therefore, as { HARQ-ACK (0), HARQ-ACK (1) }={ ACK, ACK}, table look-up 3, its correspondence be state 4,2 corresponding bit information b (0), b (1) is (1,1).
When base station is detected, detecting b (0), b (1)=(1,1), by tabling look-up 3, knowing that UE correctly receives the PDSCH on PCC and SCC#1.Do not feed back the PDSCH reception condition on SCC#2 due to UE, therefore, in the present embodiment, base station is preferably only dispatched on PCC and the SCC that reserves in advance in advance.Or in other words, the present embodiment is more suitable for the scene that 2 downlink component carriers carry out being polymerized, and at this time, UE can feed back the reception condition of the PDSCH of these 2 downlink component carriers, and without the need to carrying out the logical AND of intercarrier.
The scheme that above-described embodiment 1 and 2 proposes, both can be used alone, also can combinationally use.When being 2 as being the carrier number of terminal configuration when base station, preferably adopt the scheme of above-described embodiment 2, and when base station be the carrier number of terminal configuration more than 2 time, the preferably scheme of employing embodiment 1.
Embodiment 3
The present embodiment provides a kind of uplink control signaling transmission method, terminal first determines according to the ACK/NACK response message of N number of PDSCH that will feed back the response result information representing the response of configuration carrier wave, by determined response result information and CSI, the Physical Uplink Control Channel appointed with base station sends.
Suppose that the ACK/NACK response message of N number of PDSCH that will feed back takies M-bit position altogether, CSI is periodic channel state information, and its periodic channel amount of state information is Y, and the transmitted bit of the Physical Uplink Control Channel that terminal and base station are appointed is X bit to the maximum; Now, according to the ACK/NACK response message of N number of PDSCH that will feed back, terminal determines representing that the process of the response result information that configuration carrier wave is replied is as follows:
Terminal judges whether (M+Y)≤X, if so, is then defined as response result information by the ACK/NACK response message of this M-bit position; If not, the ACK/NACK response message of terminal to N number of PDSCH that will feed back carries out spatial logic and operation respectively, is defined as W response message, then judges whether (Y+W)≤X, if so, this W response message is defined as response result information by terminal; Otherwise the ACK/NACK response message of N number of PDSCH is mapped as 2 bit informations by the mapping relations according to setting by terminal, and this 2 bit information is defined as response result information.
Wherein, the mapping relations of setting as shown in above-mentioned table 2 or table 3, can also be not limited to the mapping relations shown in table 2, table 3 certainly.

If UE detects that DL CC#0/1/2 has 3 PDSCH altogether, respectively corresponding streams of code words is detected again, obtain corresponding ACK/NACK response message, for DL CC#0/1, owing to all containing 2 streams of code words, the ACK/NACK response message of corresponding 3 PDSCH is HARQ-ACK (0), HARQ-ACK (1), HARQ-ACK (2), HARQ-ACK (3) and HARQ-ACK (4), now, the ACK/NACK response message of 3 PDSCH takies 5 bits altogether, i.e. M=5.

When the cycle CSI needing feedback is 11 bits, namely Y equals 11, terminal judges is known due to M+Y=5+11 > 13, i.e. (M+Y) > X, judge known W+Y=3+11 > 13 again, i.e. X < (Y+W), therefore, UE is by the mapping relations of the ACK/NACK response message of these 3 PDSCH according to setting, be mapped as 2 bit information b (0), b (1), again by this 2 bit information b (0), b (1) and 11 bit period CSI sends on the Physical Uplink Control Channel appointed with base station.
When the cycle CSI needing feedback is 10 bits, namely Y equals 10, terminal judges is known, terminal judges is known due to M+Y=5+10 > 13, i.e. (M+Y) > X, then judge known W+Y=3+10=13, i.e. W+Y=X, therefore, W (namely 3) response message after spatial logic and operation and 10 bit period CSI send by UE on the Physical Uplink Control Channel appointed with base station.
When the cycle CSI needing feedback is 4 bits, namely Y equals 4, terminal judges is known, M+Y=5+4 < 13, i.e. (M+Y) < X, therefore, M-bit position (i.e. 5 bits) response message and 4 bit period CSI send by UE on the Physical Uplink Control Channel appointed with base station.
When base station is detected, then according to cycle CSI amount of bits, according to corresponding manner decoding, obtain the ACK/NACK response message of the PDSCH that corresponding cycle CSI and UE receives.
