Description
Technical field
The present invention relates to digital communicating field, particularly relate to a kind of uplink control signaling sending method and equipment.
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 (HARQ, HybridAutomaticRepeatRequest) technology just becomes the focus endeavouring to study in the communications field.
At long evolving system (LTE, LongTermEvolution) in descending HARQ, Physical Downlink Shared Channel (PDSCH, PhysicalDownlinkSharedChannel) ACK/NACK (Acknowledgement/NegativeAcknowledgement) response message, at terminal (UE, UserEquipment) Physical Uplink Shared Channel (PUSCH is not had, PhysicalUplinkSharedChannel) time, be that row control channel (PUCCH, PhysicalUplinkControlChannel) is upper physically to send.LTE defines multiple PUCCH format (format), comprise PUCCHformat1, 1a, 1b and format2, 2a, 2b, wherein format1 is used for sending the dispatch request (SR of UE, SchedulingRequest) signal, format1a and 1b is used for the response message of feedback 1 bit and the response message of 2 bits respectively, format2 is used for sending descending channel condition information (CSI, ChannelStateInformation), format2a is used for sending the response message of CSI and 1 bit, format2b is used for sending the response message of CSI information and 2 bits.
In LTE system, at frequency division duplex system (FDD, FrequencyDivisionDuplex) in, because ascending-descending subframes is one to one, so when PDSCH only comprises a transmission block (or claiming streams of code words), UE will feed back the response message of 1 bit, and when PDSCH comprises two transmission blocks, UE will feed back the response message of 2 bits.
In LTEFDD system, when UE needs to send SR and response message simultaneously: (represent when sending negativeSR and do not need dispatch request), UE sends the response message of 1 bit or 2 bits in the ACK/NACKPUCCH resource distributing to it, and when sending positiveSR (dispatch request is carried out in expression), UE sends 1 bit or 2 bit response messages in the SRPUCCH resource distributing to it; When UE needs to send response message and CSI information simultaneously, if subframe is normal cyclic prefix, as shown in Figure 1, the response message of 1 bit or 2 bits is modulated in second pilot tone of each time slot, format2a or 2b is adopted to send, if subframe is extended cyclic prefix, as shown in Figure 2, by 1 bit or 2 bit response messages and CSI information consolidation coding, format2 transmission is adopted to send.
At IMT-Advanced (InternationalMobileTelecommunications-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 (InternationalTelecommunicationUnion-Advanced, referred to as ITU-Advanced) requirement, as the senior Long Term Evolution (LongTermEvolutionAdvanced 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 (CarrierAggregation, 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, the conclusion obtained 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 for each component carrier to feed back the 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 the PDSCH for each downlink component carrier to feed back the 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 response message feeding back the PDSCH transmission of this multiple downlink component carrier on PUCCH, and those response messages are sent by the upstream components carrier wave of a UE-specific; And for SR information, UE only sends a SR, and this SR informational needs is sent by a upstream components carrier wave based on subscriber equipment (UE-specific), for CSI information, this CSI information also needs to be sent by the upstream components carrier wave of a UE-specific.
So in lte-a system, if when UE needs to send SR information and response message simultaneously, there is the situation that multiple response message and SR information send on a upstream components carrier wave simultaneously, equally, if when UE needs to send response message and CSI information simultaneously, there is the situation that multiple response message and CSI information send on a upstream components carrier wave simultaneously, but the method directly continuing to use FDD in R8 cannot solve the problem that multiple response message sends with SR, CSI respectively simultaneously.

Detailed process is described below:
In carrier aggregation system, one is comprised for bearing downlink configuration instruction (DAI in the PDCCH that each PDSCH is corresponding, DownlinkAssignmentIndicator) control domain, a downlink component carrier carries a PDSCH (supporting one or two streams of code words), and described DAI is accumulated to the downlink component carrier number that current downlink component carrier has sent to UE for representing in a transmitting procedure.
In a transmitting procedure, base station sends multiple downlink component carrier to UE, and carry DAI in the control domain of the PDCCH that the PDSCH that carries of row component carrier is corresponding in each of the lower, represent the downlink component carrier number sending to UE accumulative in current transmission process, this downlink component carrier number comprises current downlink component carrier, downlink component carrier number VDAIDL in this article represented by DAI represents, described DAI has n-bit.
When UE receives in this transmitting procedure after all downlink component carriers, the control domain of the PDCCH that the PDSCH carried from last downlink component carrier is corresponding, extract described V
dAI dL.Described " last " is determined according to the sequence number of downlink component carrier.UE is first according to V
dAI dLthe number of the downlink component carrier received with oneself judges whether downstream arrangements information dropout occurs, if, then described response message is set to the information (representing with binary system " 00 " content that response message is corresponding in this paper embodiment) representing DTX, if there is not downstream arrangements information dropout, then determine the number of the correct PDSCH received further, arrange the described response message number of correct response (ACK) to represent, namely the content of response message is the binary number representing correct response number, or determine the number of the PDSCH of garbled-reception, arrange the described response message number of wrong responses (NACK) to represent, namely the content of described response message is the binary number representing wrong responses number.

In the present embodiment, described response message is represented by 2 bits (b (0) b (1)), in other embodiments, when response message adopts high order modulation, namely operable bit number more than 2 time, still can adopt sending method of the present invention.
For convenience, if the number of the downlink component carrier having the PDSCH of corresponding PDCCH to transmit that UE receives is U
dAI, the downlink component carrier number not having the PDSCH of corresponding PDCCH to transmit is N
sPS, after UE receives PDSCH:
UE judges
time, then think and downstream arrangements information dropout occurs, namely have PDCCH to lose, the downlink component carrier of the carrying PDSCH received is less than the downlink component carrier that base station sends, b (0) b (1)=[00] is set, to represent, downstream arrangements information dropout occurs;
UE judges
time, then think and downstream arrangements information dropout does not occur, then determine the correct number being carried on the PDSCH on downlink component carrier received further, namely the number of the ACK fed back is needed, determine the content of b (0) b (1) according to described number, the downlink component carrier of described correct reception refers to U
dAI+ N

| 1 | 1，1 |
| 2 | 1，0 |
| 3 | 0，1 |
| 4 | 1，1 |
| 5 | 1，0 |
When the SR (positiveSR) of described response message and dispatch request sends on same upstream components carrier wave, described UE sends above-mentioned b (0) b (1) on the upstream components carrier wave of SRPUCCH.
When described response message and CSI send on same upstream components carrier wave, if the Cyclic Prefix of present sub-frame is normal cyclic prefix, above-mentioned b (0) b (1) is modulated in second pilot tone of each time slot in described subframe, format2b is adopted to send, if the Cyclic Prefix of present sub-frame is extended cyclic prefix, by above-mentioned b (0) b (1) and CSI information consolidation coding, format2 is adopted to send.Described present sub-frame refers to the subframe for carrying the information representing response message.
Preferably, when the PDSCH of downlink component carrier carrying only comprises a streams of code words, the response that this PDSCH is corresponding is response corresponding to this streams of code words (ACK or NACK); When the PDSCH of downlink component carrier carrying comprises two streams of code words, the response that this PDSCH is corresponding is the result that the corresponding respectively response of these two streams of code words obtains after the binding of space, namely the reception result (ACK or NACK) of UE to these two streams of code words carries out space binding, determines that described PDSCH is correct reception or garbled-reception according to space binding result.Wherein said space binding refers to only have when the response message of two streams of code words is all ACK, and the response message after binding is ACK, otherwise is NACK.
Fig. 4 gives the UE schematic diagram how determining the response of PDSCH.In this schematic diagram, suppose have 3 downlink component carriers #1, #2, #3, carry PDSCH#1, #2, #3 respectively, wherein PDSCH#1 supports two streams of code words, and therefore, UE detects two of PDSCH#1 streams of code words, obtain the response that two streams of code words are corresponding, when the response of two streams of code words is ACK, the response ACK#1 of PDSCH#1 is ACK, otherwise is NACK; In like manner, for PDSCH#2, obtain the response ACK#2 of PDSCH#2; For PDSCH#3, it only has a streams of code words, and thus the response ACK#3 of PDSCH#3 is exactly the result that this streams of code words detects, if be ACK, then ACK#3 is ACK, otherwise is NACK.
The equipment realizing said method comprises: comprise receiving element, response message generation unit and transmitting element, wherein:
Described receiving element, for receiving the PDSCH be carried on downlink component carrier that base station sends;
Described response message generation unit, for when judging downstream arrangements information dropout occurs, will represent the content of the response message of the PDSCH that the information of DTX carries as downlink component carrier; And when judging downstream arrangements information dropout does not occur, by the number information being carried on the PDSCH on downlink component carrier correctly received, or the number information being carried on the PDSCH on downlink component carrier of garbled-reception, as the content of the response message of the PDSCH of downlink component carrier carrying;
