Description

A kind of uplink control signaling transmission method and terminal

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 to data communication that develops rapidly of digital communication system is had higher requirement, but, badly Channel under, especially in high data rate or high-speed mobile environment, multi-path jamming and Doppler frequency shift etc. severely impact Systematic function.Therefore, effective error-control technique, especially mix automatic repeat request (Hybrid Automatic Repeat Request, HARQ) technology just become the communications field endeavour research focus.

In the descending HARQ of long evolving system (LTE:Long Term Evolution), Physical Downlink Shared Channel ACK/NACK (the ACK/NACK:Acknowledgement/ of (PDSCH:Physical Downlink Shared Channel) Negative Acknowledgement) response message, when terminal (UE:User Equipment) does not has physical uplink to share letter During road (PUSCH:Physical UplinkShared Channel), it is to go physically to control channel (PUCCH:Physical Uplink ControlChannel) upper transmission.

In current LTE system, Physical Uplink Control Channel can support multiple upstream control signaling, including correct/error Response message, (CSI:Channel State Information, which includes CQI to channel condition information (CQI:Channel Quality Indicator), precoding matrix indicators (PMI:Precoding Matrix Indicator) and order designator (RI:Rank Indicator)), dispatch request (SR:Scheduling Request), and The combination that they send simultaneously.

LTE defines multiple PUCCH format (format), and including PUCCH format 1/1a/1b, (its channel architecture shows It is intended to as shown in Figure 1) and format 2/2a/2b (its channel architecture schematic diagram is as shown in Figure 2), wherein format 1 is used for sending out Send ACK/NACK response message and the ACK/ of 2 bits that the dispatch request of UE, format 1a and 1b be respectively intended to feed back 1 bit NACK response message, format2 is used for sending descending channel condition information, and format 2a is used for sending CSI and 1 bit ACK/NACK response message, 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), owing to ascending-descending subframes is one to one, so working as When PDSCH only comprises a transmission block, UE to feed back the ACK/NACK response message of 1 bit, when PDSCH comprises two transmission blocks Time, UE to feed back the ACK/NACK response message of 2 bits.So in LTE FDD system, when UE need to send simultaneously SR and During ACK/NACK response message: when sending negative SR (expression need not dispatch request), UE is distributing to its ACK/ 1 bit or 2 bit ACK/NACK response message is sent in NACK PUCCH resource, and (the table as positive SR to be sent Show the request of being scheduling), UE is distributing to send 1 bit in its SRPUCCH resource or 2 bit ACK/NACK response disappears Breath；When UE needs to send ACK/NACK response message and CSI information simultaneously, if subframe is normal cyclic prefix, by 1 bit Or the ACK/NACK response message modulation of 2 bits is in second reference signal of each time slot, uses format2a/2b to send out Send, if subframe is extended cyclic prefix, by 1 bit or 2 bit ACK/NACK response message and CSI information consolidation coding, adopt Send with format 2 transmission.

And in time division duplex (TDD) system of LTE, be no longer one to one due to ascending-descending subframes, according to difference Ascending-descending subframes configuration, a sub-frame of uplink sometimes needs to feed back the ACK/NACK response message of multiple descending sub frame, this In multiple descending sub frames corresponding for sub-frame of uplink are referred to as binding window (bundling window).In LTE, fixed Two kinds of ACK/NACK feedback models of justice: one is binding pattern (bundling), the core concept of the method is needing to exist The ACK/NACK response message of the transmission block corresponding to each descending sub frame of this sub-frame of uplink feedback carries out logic and operation, if One descending sub frame has 2 streams of code words, and UE to feed back the ACK/NACK response message of 2 bits, if each subframe only one of which Word stream, UE to feed back the ACK/NACK response message of 1 bit；Another kind be multiplexer mode (multiplexing, namely Multiplexing with channelselection, also referred to as Channel assignment), the core concept of this pattern is to utilize difference PUCCH channel and this channel on different modulation symbols represent the difference of descending sub frame that needs feed back at this sub-frame of uplink Feedback states, if there being multiple word stream on descending sub frame, then is first entered by the ACK/NACK that multiple word streams of descending sub frame feed back Carry out Channel assignment again after row logical AND (also referred to as spatial bundling, space bindings), then use PUCCH Format 1b sends.It is to say, the 2 bit information b (0) carried by PUCCH format1b and b (1), and The index of PUCCH channel, represents 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, its sending method Different with foregoing FDD system.In TDD, when ACK/NACK response message needs to send out with SR or CQI simultaneously When sending, UE, by the multiple ACK/NACK response message advanced person's row spaces binding in binding window, obtains each descending sub frame corresponding ACK/NACK response message, then according to have passed through in binding window after the binding of space as the number of ACK, obtains corresponding dibit B (0), b (1), then by the PUCCH corresponding to SR by b (0), b (1) sends (has Positive SR to send when simultaneously Time), maybe by second reference signal being modulated at PUCCH format 2b, or by after b (0), b (1) and CQI combined coding PUCCH format 2 sends (scene that two kinds of situations send corresponding to CQI Yu ACK/NACK simultaneously below).Wherein, tie up After determining to have passed through space binding in window, the number for ACK has default mapping relations with b (0), b (1), as shown in table 1:

Table 1: be the number mapping relations with b (0), b (1) of ACK after have passed through space binding in binding window

In IMT-Advanced (International MobileTelecommunications-Advanced, letter It is referred to as IMT-Advanced) in system, it is possible to realize the high-speed transfer of data, and there is bigger power system capacity, move at low speed In the case of dynamic, focus covers, the peak rate of IMT-Advanced system can reach 1Gbit/s, at high-speed mobile, wide area In the case of covering, 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 of the evolution standard of LTE Evolution Advanced, referred to as LTE-A) system needs to support bigger system bandwidth (reaching as high as 100MHz), and Need the existing standard of backward compatibility LTE.On the basis of existing LTE system, the bandwidth of LTE system can be merged Obtaining bigger bandwidth, this technology is referred to as carrier aggregation (Carrier Aggregation, referred to as CA) technology, this skill Art can improve IMT-Advance system the availability of frequency spectrum, alleviate frequency spectrum resource in short supply, and then optimize frequency spectrum resource profit With.

The LTE system bandwidth of described carrier aggregation is considered as component carrier frequency (Component Carrier, referred to as frequency Spectrum), each component carrier frequency is referred to as a community (Cell), say, that a frequency spectrum can be by n component carrier frequency (Cell) it is polymerized.By n community of frequency domain, (component carries the resource of one R10UE (User Equipment, subscriber equipment) Frequently) constituting, wherein, a community is referred to as main plot (Primary cell), and remaining community is referred to as secondary cell (Secondary cell)。

Introduce after carrier aggregation, currently begging for about downlink component carrier and PDSCH transmission block and HARQ process relation In Lun, a groundwork it is assumed to be when not using space division multiplexing, a corresponding PDSCH transmission of downlink component carrier Block and a HARQ process, say, that UE needs a PDSCH transmission block for each component carrier to feed back 1 bit ACK/NACK response message.And when using space division multiplexing, LTE-A current regulations, could support up 2 transmission blocks.Therefore, when adopting When using space division multiplexing, UE needs to feed back the ACK/NACK response of 2 bits for 2 PDSCH transmission blocks of each downlink component carrier Message.

In lte-a system after have employed spectrum aggregating technology, upstream bandwidth and downlink bandwidth just can include multiple Component carrier.When there is, on multiple downlink component carriers, the PDSCH being scheduled to certain UE base station, and when UE does not has at present sub-frame When having PUSCH to be sent, terminal needs to feed back the ACK/NACK of the PDSCH transmission of these multiple downlink component carriers on PUCCH Response message.A current job it is assumed that these ACK/NACK response message are up by a UE-specific Component carrier sends；For SR information, a current job it is assumed that UE only sends a SR, and this SR information is to pass through The upstream components carrier wave of one UE-specific sends, and for CSI information, a current job it is assumed that CSI information is logical The upstream components carrier wave crossing a UE-specific sends.

In lte-a system, current work is it is assumed that for SR information, UE uses PUCCH format1 to send, right PUCCH format 2 is used to send in CSI, UE, for ACK/NACK response message, except using in LTE Definition PUCCH format 1a and 1b, Channel assignment (multiplexing with channel selection) outward, LTE-A adds a kind of new form based on DFT-s-OFDM, for sending the ACK/NACK response message of more heavy load, its Channel architecture schematic diagram is as it is shown on figure 3, for the ease of describing, be referred to as PUCCH Format 3 by this structure.Wherein UE uses Which kind of mode is carried out feeding back ACK/NACK and is configured by high level.

In LTE-A FDD system, when being configured with UE and using PUCCH format 3 feeding back ACKs/NACK, if UE exists During present sub-frame SR to be sent, then UE is by SR and multiple ACK/NACK response message combined codings, then at PUCCH Send on format 3.And for being configured to use Channel assignment to carry out feeding back ACK/NACK UE, if present sub-frame is simultaneously During SR or CSI to be sent, if continuing to use the method for TDD in LTE, from table 1 it will be seen that work as the b that base station receives (0), during b (1)=(1,1), base station will be unable to judge that UE has correctly received 1 or has correctly received 4 PDSCH.Therefore, Considering from the robustness point of system, base station can assume that and receives only 1, thus, if having had correctly received 4 for UE For the scene of PDSCH, base station is also intended to retransmit, thus throughput of system hydraulic performance decline.Accordingly, it would be desirable to the ACK/NACK improved With SR/CSI sending method simultaneously.
