Description

A kind of uplink control signaling transmission method and subscriber equipment

Technical field

The present invention relates to digital communicating field, particularly relate to terminal in a kind of large bandwidth multi-carrier system and uplink control signaling transmission method and subscriber 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 (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 subscriber equipment (UE:User Equipment) does not have Physical Uplink Shared Channel (PUSCH:PhysicalUplink Shared Channel), be that row control channel (PUCCH:Physical UplinkControl Channel) is upper physically to send.LTE defines multiple PUCCH format (format), comprise PUCCH format 1/1a/1b and format 2/2a/2b, wherein format1 is used for sending dispatch request (SR:Scheduling Request) signal 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 (CSI:Channel), format2a is used for sending the ACK/NACK response message of CSI and 1 bit, format2b is used for sending the ACK/NACK response message of CSI information and 2 bits, during present sub-frame employing normal cyclic prefix, the structure of format2/2a/2b as shown in Figure 1, during present sub-frame employing extended cyclic prefix, the structure of format2/2a/2b as shown in Figure 2, wherein, in Fig. 1 and 2 represent pilot tone, represent data.

In LTE system, in frequency division duplex system (FDD:Frequency Division Duplex), 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, in tdd systems (TDD:Time DivisionDuplex), due to ascending-descending subframes is not one to one, that is the ACK/NACK response message that multiple descending sub frame is corresponding needs to send on the PUCCH channel of a sub-frame of uplink, wherein, the descending sub frame set that sub-frame of uplink is corresponding constitutes " bundling window ".The sending method of ACK/NACK response message has two kinds: one is binding method (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 transmission blocks, UE will feed back the ACK/NACK response message of 2 bits, if each subframe only has a transmission block, UE will feed back the ACK/NACK response message of 1 bit; Another kind is Channel assignment (multiplexing with channelselection, be called for short multiplexing) method, the core concept of the method 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 transmission block, carry out Channel assignment again after so first the ACK/NACK of multiple transmission block feedbacks of descending sub frame being carried out logical AND (being also called spatial bundling), then use PUCCH format1b to send.

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 SR PUCCH 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 pilot tone 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, format2 transmission is adopted to send.

In TDD system, when UE needs to send SR and ACK/NACK simultaneously, when sending negativeSR, UE sends bundledACK/NACK or multiple ack/nack signal in the ACK/NACK PUCCH resource distributing to it, and when sending positive SR, the PUCCH format 1b of UE employing table 1 definition in the SR PUCCH resource distributing to it sends dibit information b (0) b (1); When UE needs to send ACK/NACK response message and CSI information simultaneously, if subframe is normal cyclic prefix, b (0) b (1) shown in table 1 is modulated in second pilot tone of each time slot, format2b is adopted to send, if subframe is extended cyclic prefix, by b (0) b (1) and CSI information consolidation coding, format2 is adopted to send.Wherein basis be have passed through the U of spatial bundling by the value of b (0) b (1) _dAI+ N _sPSthe ACK/NACK of individual PDSCH determines (this U _dAI+ N _sPSindividual PDSCH is that UE detects in bundling window, wherein U _dAIrepresent the subframe sum of the PDSCH transmission that UE detects according to PDCCH on (multiple) descending sub frame, and N _sPSrepresent the number of sub frames not having the PDSCH transmission of corresponding PDCCH that UE detects on (multiple) descending sub frame)

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 CQI information, a current work supposition is CSI information is sent by the upstream components carrier wave of a UE-specific.

So in LTE-A FDD system, if when UE needs to send SR information and ACK/NACK response message on a upstream components carrier wave simultaneously, there is the situation that multiple ACK/NACK response message and SR informational needs send simultaneously, equally, if when UE needs to send ACK/NACK response message and CSI information on a upstream components carrier wave simultaneously, there is the situation that multiple ACK/NACK response message and CSI informational needs send simultaneously, some companies think that this situation can continue to use the method in LTE TDD system, but owing to can not be obtained the ACK/NACK response message of each downlink component carrier by b (0) b (1) in LTE TDD system, so base station does not know which component carrier concrete detects mistake, therefore so long as not whole component carrier all feeding back ACKs, base station all needs to retransmit all component carriers, thus reduce the throughput of system.

Introduce in different scene below, above-mentioned UE transmits uplink control signaling process.

Embodiment 1

In the present embodiment, network side is the number of the downlink component carrier of UE configuration is M, between network side and UE, the grouping information of this M of agreement downlink component carrier is in advance: UE needs M downlink component carrier to be divided into two groups, wherein one group comprises a front L downlink component carrier, and another group comprises M-L downlink component carrier (L < M).UE carries out uplink control signaling transmitting procedure as shown in Figure 4, comprises the following steps:

Step 401:UE is divided into two groups according to grouping information by needing the M of a feeding back response information downlink component carrier, and wherein one group comprises a front L downlink component carrier, and another group comprises a remaining M-L downlink component carrier;

Step 402:UE determines the response corresponding to each downlink component carrier group;

In this step, UE determines the response corresponding to this downlink component carrier group according to the response message of the PDSCH on each downlink component carrier in each downlink component carrier group, particularly, for the ACK/NACK response that downlink component carrier group is corresponding, when in this downlink component carrier group, the response message of the PDSCH of all downlink component carriers is all ACK, this response corresponding to downlink component carrier group is ACK, when being NACK or DTX (discontinuous transmission) when there being the response message of the PDSCH of one or more downlink component carrier in L component carrier, this response corresponding to downlink component carrier group is NACK.

Determine that the response message of the PDSCH of each downlink component carrier is as follows:

Be assumed to be UE and be assigned 3 downlink component carriers when being respectively downlink component carrier #1, #2, #3, wherein, downlink component carrier #1 comprises two streams of code words, and downlink component carrier #2 comprises two streams of code words, and downlink component carrier #3 comprises a streams of code words.

Now, UE determines the process of the response message of the PDSCH of above-mentioned each component carrier, as shown in Figure 3:

UE first detects two streams of code words of component carrier #1, obtain the ACK/NACK response message that two streams of code words are corresponding, when the ACK/NACK response message that two streams of code words are corresponding is ACK, the ACK/NACK response message of the PDSCH of downlink component carrier #1 is ACK, otherwise is NACK;

UE detects two streams of code words of downlink component carrier #2 again, obtain the ACK/NACK response message that two streams of code words are corresponding, when the response message that two streams of code words are corresponding is ACK, the ACK/NACK response message of the PDSCH of downlink component carrier #2 is ACK, otherwise is NACK;

UE detects downlink component carrier #3 streams of code words, and thus the ACK/NACK response message of the PDSCH of downlink component carrier #3 is exactly the result that this streams of code words detects.

The response message of the response composition corresponding to determined each downlink component carrier group and other upstream control signalings send by step 403:UE in same upstream components carrier wave, and wherein, other upstream control signalings can be SR or CSI;

Such as, UE send simultaneously SR information and each downlink component carrier group corresponding response composition response message time, can represent with b (0) the ACK/NACK response that L the component carrier of first group is corresponding, represent with b (1) the ACK/NACK response that M-L the component carrier of second group is corresponding;

Suppose M=2, during L=1, as shown in Figure 5, the response message of the PDSCH of 2 downlink component carriers is { ACK, DTX}, here DTX refers to that UE there is no about the relevant PDCCH information of the 2nd component carrier, if the response corresponding to first downlink component carrier group is ACK, so b (0)=1, the response corresponding to second downlink component carrier group is DTX, so b (1)=0, now, UE sends ' 10 ' in the SR PUCCH resource distributing to SR, namely represents the response message of the response composition corresponding to two downlink component carrier groups;

When the response message of PDSCH corresponding to 2 downlink component carriers is { ACK, during NACK}, if the response corresponding to first downlink component carrier group is ACK, so b (0)=1, if the response corresponding to second downlink component carrier group is NACK, so b (1)=0, now, UE sends ' 10 ' in the SR PUCCH resource distributing to SR, namely represents the response message of the response composition corresponding to two downlink component carrier groups;

If M=3, get L=1, as shown in Fig. 6 (a).The response message of the PDSCH that 3 downlink component carriers are corresponding is { ACK, NACK, ACK}, response corresponding to first downlink component carrier group is ACK, so b (0)=1, the response of the PDSCH of one-component carrier wave that has in second downlink component carrier group is NACK, so b (1)=0, UE sends ' 10 ' in the SR PUCCH resource distributing to it, namely represents the response composition response message corresponding to two downlink component carrier groups;

If M=3, get L=2, as shown in Fig. 6 (b).The response message of the PDSCH of 3 downlink component carriers is { ACK, NACK, ACK}, the response message of the PDSCH of a downlink component carrier is had to be NACK in first downlink component carrier group, so b (0)=0, in second downlink component carrier group, the response message of the PDSCH of all downlink component carriers is ACK, so b (1)=1, UE sends ' 01 ' in the SR PUCCH resource distributing to it, namely represents the response message of the response composition corresponding to two downlink component carrier groups;

If M=4, get L=2, the response message of the PDSCH of 4 downlink component carriers is { ACK as shown in Figure 7, ACK, ACK, NACK}, in first downlink component carrier group, the response message of the PDSCH of all downlink component carriers is ACK, so b (0)=1, the response message of the PDSCH of a downlink component carrier is had to be NACK in second downlink component carrier group, so b (1)=0, UE sends ' 10 ' in the SR PUCCH resource distributing to it, namely represents the response message of the response composition corresponding to two downlink component carrier groups;

Suppose M=5, get L=2, as shown in Fig. 8 (a).The response message of the PDSCH of 5 downlink component carriers is { ACK, ACK, NACK, ACK, ACK}, in first downlink component carrier group all downlink component carriers PDSCH response message be ACK, so b (0)=1, the response message of the PDSCH of a downlink component carrier is had to be NACK in second downlink component carrier group, so b (1)=0, UE sends ' 10 ' in the SR PUCCH resource distributing to it, namely represents the response message of the response composition corresponding to two downlink component carrier groups;

Suppose M=5, get L=3, as shown in Fig. 8 (b).The response message of the PDSCH of 5 downlink component carriers is { ACK, ACK, NACK, ACK, ACK}, the response message of the PDSCH of a downlink component carrier is had to be NACK in first downlink component carrier group, so b (0)=0, in second downlink component carrier, the response message of the PDSCH of all downlink component carriers is ACK, so b (1)=1, UE sends ' 01 ' in the SR PUCCH resource distributing to it, namely represents the response message of the response composition corresponding to two downlink component carrier groups.
