Description

The method and apparatus sending/receive ack/nack information in communication system
The application is filing date on 06 16th, 2008, Application No. 200880020321.0, invention entitled " movement For the method and apparatus that distributes and obtain ack/nack resources in communication system " the division Shen of application for a patent for invention Please.
Technical field
The present invention relates generally to mobile communication system, in particular it relates to for effectively using for controlling information transmission The method and apparatus of resource.
Background technology
In communication system such as LTE (Long Term Evolution) system, confirm (ACK)/negative ACK (NACK) feedback information, make It is a class uplink control information, is intended to indicate that and is receiving the downlink that hybrid automatic repeat-request (HARQ) is applied Send signal successful/failed in data.
In LTE system, send believing in the presence/absence of classifying of data for up-link control according to up-link The transmission form of breath.When sending data and the information of control the most simultaneously, LTE system time division multiplex (TDM) multiplexing Data and control information, and before transmitting data and control information MAP are provided to the T/F sending distribution for data Source.But, when only sending control information and do not have data to send, LTE system use is distributed by the transmission of control information Special frequency band.Currently, in standards meetings, just physical uplink control channel (PUCCH) is defined as only sending The physical channel of control information, and PUCCH is mapped to distributed special frequency band.
Fig. 1 is to be shown in 3GPP LTE system on uplink for controlling the physical channel PUCCH that information sends The schematic diagram of transmission structure.In FIG, transverse axis represents time domain, and the longitudinal axis represents frequency domain.More specifically, Fig. 1 illustrates one Time domain in individual subframe 102 and the frequency domain in system transmission bandwidth 110.
With reference to Fig. 1, as a length of 1ms of subframe 102 of the basic transmitting element of up-link, and a subframe includes Two time slots 104 and 106, each a length of 0.5ms.Time slot 104 and 106 each includes multiple SC-FDMA code element 111-123 (131-143).Fig. 1 illustrates a time slot and includes the example of 7 SC-FDMA code elements.
In time-frequency domain, the elementary cell of resource is resource element (RE).SC-FDMA symbol index can be passed through (for downlink, OFDM symbol indexes) and sub-carrier indices define RE.The elementary cell of resource distribution is Resource Block (RB), such as RB108 and 109.RB108 and 109 includes multiple subcarrier and multiple SC-FDMA code element.The example that figure 1 illustrates In son, 12 subcarriers and 14 the SC-FDMA code elements that constitute 2 time slots constitute a RB.
The frequency band being mapped to reference to Fig. 1, PUCCH and expression RB's and system transmission bandwidth 110 one or both ends phase Reference marker 108 or the reference marker 109 answered are corresponding.PUCCH can apply frequency hopping to increase frequency to divide during a subframe Collection, and in such a case, it is possible to by the frequency hopping of time slot.Base station (or node B) can distribute multiple for PUCCH send RB, to agree to the transmission of the control information from multiple users.
With reference to Fig. 1, control information #1 that the preallocated frequency band 108 in the first time slot 104 sends experienced by jumping After Pin, another the preallocated frequency band 109 in the second time slot 106 is sent.But, pre-in the first time slot 104 Control information #2 sent on the frequency band 109 of distribution is after experienced by frequency hopping, and another in the second time slot 106 is preallocated Sent on frequency band 108.
In FIG in example illustrated, in subframe 102, by reference marker 111,112,116,117,138,139, 143 and 144 or reference marker 131,132,136,137,118,119,123 and 124 represent SC-FDMA code element in send control Information processed, and by reference marker 113,114,115,140,141 and 142 or reference marker 133,134,135,120, 121 and the 122 SC-FDMA code elements represented send pilot tone (or reference signal (RS)).Including predetermined sequence pilot tone by with Estimate in the channel for the correlation demodulation at receiving terminal.For controlling the number of the SC-FDMA code element that information sends, for RS Number and their positions in subframe of the SC-FDMA code element sent are all to be given by the way of example at this, and Type according to desired transmission control information and/or system are operated and change by these.
Generally, code division multiplexing (CDM) is for being multiplexed into phase for the ACK/NACK sent on the PUCCH of different user With in RB.As it has been described above, multiple RB sent for PUCCH can be distributed in base station, to agree to the ACK/ from multiple users The transmission of NACK.
Using Zadoff-Chu (ZC) sequence as control information CDM sequence the most under discussion.Because Zadoff- Chu sequence has constant signal level (or constant envelope) in time domain and frequency domain, so it has the equal power in good peak Than (Peak-to-Average Power Ratio, PAPR) characteristic and show outstanding channel estimating performance in a frequency domain.
In general it is assumed that a length of 12 samplings of the Zadoff-Chu sequence for PUCCH, its number is equal to being included in RB In subcarrier number.In this case, because the maximum possible number of the different cyclic shift value of Zadoff-Chu sequence It is 12, so being possible by distribute different cyclic shift value most 12 PUCCH being multiplexed into a RB to PUCCH 's.
Fig. 2 illustrates and sends in ACK/NACK on the PUCCH have said structure, uses Zadoff-Chu sequence not With cyclic shift value, the ACK/NACK of each user is multiplexed into the example in identical RB.In fig. 2, the longitudinal axis represents The cyclic shift value 200 of Zadoff-Chu sequence.It is being considered as the TU (Typical Urban, typical urban) of wireless channel model In model, orthogonality is not had to lose suddenly the channel maximum of (abrupt loss) because of multiplexing can be experienced in a RB Possible number is 6, so Fig. 2 illustrates the feelings of 6 ack/nack signals 202,204,206,208,210 and 212 experience multiplexing Condition.Fig. 2 illustrates and uses identical RB with identical Zadoff-Chu sequence to send the example of ACK/NACK as follows: use Cyclic shift " 0 " 214 sends the ACK/NACK202 from UE#1；Cyclic shift " 2 " 218 is used to send the ACK/ from UE#2 NACK204；Cyclic shift " 4 " 222 is used to send the ACK/NACK206 from UE#3；Cyclic shift " 6 " 226 is used to send From the ACK/NACK208 of UE#4；Cyclic shift " 8 " 230 is used to send the ACK/NACK210 from UE#5；And use circulation Displacement " 10 " 234 sends the ACK/NACK212 from UE#6.
In addition to CDM based on Zadoff-Chu sequence controls information transmission, can by application time domain extraly just Sequence is handed over to improve the multiplexing capacity of the PUCCH carrying control information.
The exemplary of orthogonal sequence includes Walsh sequence.For the orthogonal sequence of a length of M, there is M and meet them Between the sequence of orthogonality.More specifically, for 1 bit control information, such as ACK/NACK, can be by before transmitting Time domain orthogonal sequence is applied to SC-FDMA code element that ACK/NACK be mapped to improve its multiplexing capacity.Can pass through will The time interval applying time domain orthogonal sequence wherein is restricted to a time slot or shorter, makes to be changed by wireless channel to cause Loss of orthogonality minimizes.Such as, the orthogonal sequence of a length of 4 is applied to 4 in one time slot be used for ACK/NACK and send out The SC-FDMA code element sent, and in one time slot the orthogonal sequence of a length of 3 is applied to 3 SC-being used for RS transmission FDMA code element.Substantially, for ACK/NACK and RS, can be used by the cyclic shift value using Zadoff-Chu sequence Family identifies, and by orthogonal sequence, available extra user identifies.For the correlation reception of ACK/NACK, since it is desired that Based on being mapped to the RS of ACK/NACK one to one, so limited the multiplexing energy of ack/nack signal by the RS being mapped to ACK/NACK Power.
Fig. 3 illustrates in the PUCCH structure sent for ACK/NACK, except the different circulations of Zadoff-Chu sequence Use time domain orthogonal sequence that the ACK/NACK of each user is multiplexed into the example in identical RB outside shift value.In figure 3, The longitudinal axis represents the cyclic shift value 300 of Zadoff-Chu sequence, and transverse axis represents time domain orthogonal sequence 302.It is being considered as wireless channel In TU (typical urban) model of model, their multiplexing can be carried out in a RB and not have orthogonality to lose suddenly used The maximum number of cyclic shift value be 6, and if the extra orthogonal sequence 364,366 and 368 using 3 a length of 4, then At most can with 6*3=18 ack/nack signal of multiplexing 304,306,308,310,312,314,316,318,320,322,324, 326,328,330,332,334,336 and 338.
Fig. 3 illustrates and uses the identical RB and identical Zadoff-Chu sequence sent for ACK/NACK as follows Example: use cyclic shift " 0 " 340 and orthogonal sequence " 0 " 364 to send the ACK/NACK304 from UE#1；Use cyclic shift " 0 " 340 and orthogonal sequence " 1 " 366 send the ACK/NACK306 from UE#2；Use cyclic shift " 0 " 340 and orthogonal sequence " 2 " 368 send the ACK/NACK308 from UE#3；Until；Cyclic shift " 10 " 360 and orthogonal sequence " 0 " 364 is used to send ACK/NACK334 from UE#16；Cyclic shift " 10 " 360 and orthogonal sequence " 1 " 366 is used to send the ACK/ from UE#17 NACK336；And use cyclic shift " 10 " 360 and orthogonal sequence " 2 " 368 to send the ACK/NACK338 from UE#18.Long Degree is the orthogonality that the orthogonal sequence 364,366 and 368 of the orthogonal code of 4 meets between them.
PUCCH sends resource information required in ACK/NACK include: (i) represents which RB to send ACK/ by The RB information of NACK, the circular shift information of (ii) Zadoff-Chu sequence, and (iii) orthogonal sequence information.
The invention provides a kind of control channel sent by definition and the resource sent for ACK/NACK by base station Between detailed map relation effectively use resource the method improving receptivity so that base station and UE can be with common identification The resource information sent for UE ACK/NACK.
The elementary cell constituting downlink control channel is to control channel element (CCE).One downlink controls letter Road includes that one or more CCE, each CCE include multiple RE.The increase of the CCE number of downlink control channel can reduce For being mapped to the channel coding rate of the control information of downlink control channel so that may again obtain chnnel coding.
Fig. 4 illustrates the example generating downlink control channel.More specifically, Fig. 4 illustrates following example: for always N altogetherCCEIndividual CCE401-409, uses these 4 CCE of CCE#0 401-CCE#3 404 to generate the downlink control channel of UE#1 430；These 2 CCE of CCE#4 405-CCE#5406 are used to generate the downlink control channel 422 of UE#2；Use CCE#6 407 these 1 CCE generate the downlink control channel 416 of UE#3；This 1 CCE of CCE#7 408 is used to generate UE#4's Downlink control channel 417；And use CCE#NCCE-1 409 these 1 CCE generate the downlink control channel of UE#5 418.It is to say, base station sends the down link control information of UE#1-UE#5 in any subframe.When multiple CCE are included in Time in one downlink control channel, CCE can be continuous print as shown in Figure 4, or can be scattered namely discontinuous 's.The position of CCE depends on that system operates.
UE can use N altogetherCCEPerform decoding on the downlink control channel that individual CCE generates, and detect himself Identifier (ID) time, identify corresponding channel be to UE self send down control channel.

Detailed description of the invention
The preferred embodiments of the present invention are described in detail referring now to accompanying drawing.In the following description, in order to clear and simple Clean, the known function that omission is herein incorporated and the detailed description of configuration.Define based on the function in the present invention and use at this Term, and can according to user, operator be intended to or common practice and change.Therefore, it should based on entire disclosure Content carry out the definition of term.
The invention provides a kind of improvement for realizing the effective utilization of resources and receptivity, make to send out with signal simultaneously Send the method for minimizing overhead required for the resource information that the control information for UE sends.
Further, present invention provide for the definition of the operation of following situation: by be used for RB that ACK/NACK sends, Cyclic shift value and orthogonal sequence for Zadoff-Chu sequence are used and are acted on the resource that ACK/NACK sends, and also provide A kind of method of the resource sent for ACK/NACK for distribution and management.
Embodiment 1
Embodiments of the invention 1 provide following method: provided and for UE by downlink control channel in base station In the case of the relevant information of resource that ACK/NACK sends, by preferential fixing as the money sent for UE ACK/NACK The cyclic shift value of a type of Zadoff-Chu sequence in source, and in the CCE indexed sequential increasing of downlink control channel Added-time changes the index of orthogonal sequence, and CCE is mapped to the resource sent for ACK/NACK.
Fig. 5 A and Fig. 5 B illustrates downlink control channel and the mapping between the resource that UE ACK/NACK sends Relation.
The resource sent for ACK/NACK includes: RB information RB (o) (wherein o=0,1 ..., NRB-1), it is frequency domain Resource information；Circular shift information CS (n) (wherein n=0,1 ..., NCS-1), represent Zadoff-Chu sequence cyclic shift How many samplings；And orthogonal sequence information OS (m) (wherein m=0,1 ... NOS-1).Assume to be assigned with in systems: for ACK/NACK sends the N altogether of distributionRBIndividual RB, the N altogether of Zadoff-Chu sequenceCSIndividual cyclic shift value and altogether NOSIndividual Orthogonal sequence.
Fig. 5 A and Fig. 5 B illustrates following method: by fixing use preferential in the resource that UE ACK/NACK sends The index o of the RB information sent in ACK/NACK and the circular shift information of the cyclic shift value of expression Zadoff-Chu sequence Index n, and the index m of orthogonal sequence information is sequentially increased when the CCE index k of downlink control channel sequentially increases, come CCE is mapped to one to one the resource sent for ACK/NACK.Specifically, if the index sequentially increased of orthogonal sequence is complete All use up, then cyclic shift is indexed n by this method increases by 1, is then back to from the index starting to sequentially increase orthogonal sequence.As Really cyclic shift index n uses up, then, after repeating operation above, this method will be used for the RB that ACK/NACK sends The index o of information increases by 1, the most again repeats operation above.
For by N altogetherCCEThe rule that individual CCE is mapped to the most one to one for the resource of ACK/NACK transmission can To be summarized by the following.Assume ACK/NACK is only mapped to the RB sending distribution into ACK/NACK, preset equation below (1).It is to say, do not consider to feed back such as CQI (CQI) or MIMO its of relevant control information etc He is multiplexed into the situation in identical RB with ACK/NACK at control information.
CCE (k) → OS (m), CS (n), RB (o),
K=0,1 ..., NCCE-1
M=k mod NOS(m=0,1 ..., NOS-1)
N=floor (k/NOS)mod NCS(n=0,1 ..., NCS-1)
O=floor (k/ (NOS*NCS)) (o=0,1 ..., NRB-1) (1)
In superincumbent formula (1), " x mod y " represents the remainder obtained by x divided by y, and floor (z) is little Maximum integer in z.
In order to simplify description, if it is assumed that N in Fig. 5 A and Fig. 5 BRB=1, NCS=6 and NOS=3, then by CCE (k) Resource OS (m), CS (n) and the RB (o) sent for ACK/NACK it is mapped to one, as follows.
CCE (0) → OS (0), CS (0), RB (0),
CCE (1) → OS (1), CS (0), RB (0),
CCE (2) → OS (2), CS (0), RB (0),
CCE (3) → OS (0), CS (1), RB (0),
CCE (4) → OS (1), CS (1), RB (0),
CCE (5) → OS (2), CS (1), RB (0),
CCE (6) → OS (0), CS (2), RB (0),
CCE (7) → OS (1), CS (2), RB (0),
When multiple CCE constitute downlink control channel, CCE can be continuous print, or can be scattered, namely Discontinuous, this depends on that system operates.Fig. 5 A illustrates the previous case, and Fig. 5 B illustrates latter event.
Fig. 5 A illustrates following example: CCE (0), CCE (1), CCE (2) and CCE (3) composition and includes the scheduling for UE#1 The downlink control channel of control information；CCE (4) and CCE (5) composition includes the descending of the scheduling control information for UE#2 Link control channel；And CCE (6) and CCE (7) constitutes the downlink control letter including the scheduling control information for UE#3 Road.
Because UE needs only to respond the data channel sent by base station and downlink control channel and send one ACK/NACK, thus UE Choose for user to constitute each UE downlink control channel multiple CCE for UE ACK/ In the resource that NACK sends one, and perform ACK/NACK transmission by selected resource.Between base station and UE previously Under the agreement reached, the method that can be selected, by base station and UE common identification, the resource sent for UE ACK/NACK.As can Can example, exist a kind of for will be mapped to constitute UE downlink control channel CCE in there is minimum index The ACK/NACK resource of CCE is set to the method that UE is actually used in the resource that ACK/NACK sends.Therefore, illustrate in fig. 5 In example, UE#1 uses and is mapped to ACK/NACK resource OS (0) of CCE (0), CS (0) and RB (0) transmission ACK/NACK；UE#2 Use is mapped to ACK/NACK resource OS (1) of CCE (4), CS (1) and RB (0) and sends ACK/NACK；And UE#3 uses and maps ACK/NACK resource OS (0), CS (2) and RB (0) to CCE (6) send ACK/NACK.
Use aforesaid method, if it would be possible, system makes by the orthogonal sequence multiplexing for a cyclic shift The number of ack/nack signal minimizes, thus contributes to reducing from the interference between the ack/nack signal of multiple UE.At UE In the case of the wireless channel of experience changes significantly, such as in the environment of quickly movement, this operation reduces due to orthogonal sequence The penalty of the ack/nack signal caused by loss of orthogonality.
Fig. 5 B illustrates following example: CCE (0), CCE (3), CCE (6) and CCE (7) composition and includes the scheduling for UE#1 The downlink control channel of control information；CCE (1) and CCE (4) composition includes the descending of the scheduling control information for UE#2 Link control channel；And CCE (2) and CCE (5) constitutes the downlink control letter including the scheduling control information for UE#3 Road.
Have a kind of CCE's for will be mapped to have minimum index in constituting the CCE of down control channel of UE ACK/NACK resource is set to the method that UE is actually used in the resource that ACK/NACK sends.In this case, scheme in figure 5b In the example shown, UE#1 uses and is mapped to ACK/NACK resource OS (0) of CCE (0), CS (0) and RB (0) transmission ACK/NACK； UE#2 uses and is mapped to ACK/NACK resource OS (1) of CCE (1), CS (0) and RB (0) transmission ACK/NACK；And UE#3 uses It is mapped to ACK/NACK resource OS (2) of CCE (2), CS (0) and RB (0) and sends ACK/NACK.
In figure 5b in example illustrated, because only CS (0) the cyclic shift resource acting on ACK/NACK, so Can by remaining cyclic shift resource CS (1), CS (2), CS (3), CS (4) and CS (5) distribution send such as CQI information it Other of class control information.If being assigned with multiple RB sent for ACK/NACK in systems, then because only RB (0) uses In figure 5b in example illustrated, it is possible to be assigned as sending other control letters by the RB being assigned as sending remaining ACK/NACK Breath or data.
Fig. 6 illustrates base station and the information relevant with the resource being used for ACK/NACK transmission is supplied to UE to perform aforementioned behaviour The process made.
With reference to Fig. 6, in step 601, base station arranges and constitutes the CCE of downlink control channel and for UE ACK/ Mapping relations one to one between the resource that NACK sends, arrange the side of the resource that UE is sent for ACK/NACK by its acquisition Method, and provide corresponding information to UE.The resource sent for UEACK/NACK includes: the RB as frequency domain resource information believes Breath, the circular shift information of Zadoff-Chu sequence and orthogonal sequence information.Can under the agreement that base station and UE had previously been reached, By base station and UE, or by signaling from base station to UE, come the pass of mapping one to one that common identification sends for ACK/NACK System and resource acquiring method.
In step 602, base station determines whether to send down-link data channel by predetermined scheduling operation, and When base station determines transmission down-link data channel, it is determined that the resource sent for down-link data channel and transmission lattice Formula.
In step 603, base station according to the resource sent for down-link data channel determined by step 602 and Send form and send down link data information.Further, base station sends and includes sending for down-link data channel Resource and send form downlink control channel.Under the agreement that UE had previously reached between itself and base station or according to step The information sent with signal from base station in rapid 601, obtains from the downlink control channel received and sends for UE ACK/NACK Resource.
Fig. 7 illustrates UE and obtains the resource transmission ACK/ acquired in the resource sent for ACK/NACK use from base station NACK is to perform the process of aforementioned operation.
With reference to Fig. 7, in step 700, UE identifies and constitutes the CCE of downlink control channel and send for ACK/NACK Resource between mapping relations one to one, and under the agreement previously reached between base station and UE or based on from base station with Signal send information, for ACK/NACK send resource acquiring method.The resource sent for ACK/NACK includes: make For the RB information of frequency domain resource information, the circular shift information of Zadoff-Chu sequence and orthogonal sequence information.
In step 701, UE receives the data channel applying HARQ from base station and the downlink being associated controls letter Road.Downlink control channel includes the resource information of the data channel that base station sends for particular UE and represents and send form Downlink scheduling control information, and include one or more CCE.
In a step 702, UE is according to identified in step 700, CCE with between the resource that ACK/NACK sends Mapping relations and the resource acquiring method for ACK/NACK transmission, obtain from the downlink control channel received one to one Take the resource sent in ACK/NACK.
In step 703, the data channel received is decoded by UE, determines in the presence/absence of mistake, and not Deposit and generate ACK in the case of an error, and generate NACK in the presence of an error.Generate ack/nack signal, so that Repeat it repeatedly improve receptivity and expand MPS process.
In step 704, the ACK/NACK of generation is mapped to the in a step 702 acquired ACK/NACK that is used for and sends out by UE The resource sent, and send ACK/NACK.
Embodiment 2
Embodiment 2 provides following method: provided and for UE ACK/NACK by downlink control channel in base station In the case of the relevant information of resource sent, by the preferential fixing one as the resource sent for UE ACK/NACK The index of the orthogonal sequence of type, and increase along with the CCE indexed sequential of downlink control channel and change Zadoff-Chu The cyclic shift value of sequence, is mapped to the resource sent for ACK/NACK by CCE.
Fig. 8 A and Fig. 8 B illustrates downlink control channel and the mapping between the resource that UE ACK/NACK sends Relation.The resource sent for ACK/NACK includes: RB information RB (o) (wherein o=0,1 ..., NRB-1), it is frequency domain resource Information；Circular shift information CS (n) (wherein n=0,1 ..., NCS-1), represent that Zadoff-Chu sequence cyclic shift is how many Individual sampling；And orthogonal sequence information OS (m) (wherein m=0,1 ... NOS-1).Assume to be assigned with in systems: for ACK/ NACK sends the N altogether of distributionRBIndividual RB, the N altogether of Zadoff-Chu sequenceCSIndividual cyclic shift value and altogether NOSIndividual orthogonal Sequence.
Fig. 8 A and Fig. 8 B illustrates following method: by fixing use preferential in the resource that UE ACK/NACK sends In the index o and the index m of orthogonal sequence information of the RB information that ACK/NACK sends, and along with downlink control channel CCE index k sequentially increases and sequentially increases the index n of circular shift information, and this index n represents the circulation of Zadoff-Chu sequence Shift value, is mapped to the resource sent for ACK/NACK one to one by CCE.Specifically, if circular shift information suitable The index that sequence increases all is used up, then the index m of orthogonal sequence information is increased by 1 by this method, is then back to increase from beginning order Add the index of circular shift information.If the index m of orthogonal sequence information the most all uses up, then repeat operation above it After, the index o being used for the RB information that ACK/NACK sends is increased by 1 by this method, the most again repeats operation above.
For by N altogetherCCEThe rule that individual CCE is mapped to the most one to one for the resource of ACK/NACK transmission can To be summarized by the following.Under the hypothesis that only ACK/NACK is mapped to the RB sending distribution into ACK/NACK, preset following Formula (2).It is to say, do not consider by other control information of control information relevant for such as CQI or MIMO feedback etc with ACK/NACK is multiplexed into the situation in identical RB.
CCE (k) → OS (m), CS (n), RB (o),
K=0,1 ..., NCCE-1
M=floor (k/NCS)mod NOS(m=0,1 ..., NOS-1)
N=k mod NCS(n=0,1 ..., NCS-1)
O=floor (k/ (NOS*NCS)) (o=0,1 ..., NRB-1) (2)
In superincumbent formula (2), the remainder that " x mod y " expression x obtains divided by y, and floor (z) is little Maximum integer in z.
In order to simplify description, if it is assumed that N in Fig. 8 A and Fig. 8 BRB=1, NCS=6 and NOS=3, then by CCE (k) Resource OS (m), CS (n) and the RB (o) sent for ACK/NACK it is mapped to one, as follows.
CCE (0) → OS (0), CS (0), RB (0),
CCE (1) → OS (0), CS (1), RB (0),
CCE (2) → OS (0), CS (2), RB (0),
CCE (3) → OS (0), CS (3), RB (0),
CCE (4) → OS (0), CS (4), RB (0),
CCE (5) → OS (0), CS (5), RB (0),
CCE (6) → OS (1), CS (0), RB (0),
CCE (7) → OS (1), CS (1), RB (0),
When being included in downlink control channel by multiple CCE, CCE can be continuous print, or can be dispersion , namely discontinuous, this depends on that system operates.Fig. 8 A illustrates the previous case, and Fig. 8 B illustrates latter event.Tool For body, embodiment 2 is suitable for following situation: locate at any time, altogether NCCEIn individual CCE, only only a part constitutes each UE Downlink control channel.Such as, Fig. 8 A and Fig. 8 B illustrates N altogetherCCE8 CCE in individual CCE are constituted under each UE Uplink Control Channel.
Fig. 8 A illustrates following example: CCE (0), CCE (1), CCE (2) and CCE (3) composition and includes the scheduling for UE#1 The downlink control channel of control information；CCE (4) and CCE (5) composition includes the descending of the scheduling control information for UE#2 Link control channel；And CCE (6) and CCE (7) constitutes the downlink control letter including the scheduling control information for UE#3 Road.
Because UE needs only to send one in response to the data channel sent by base station and downlink control channel ACK/NACK, thus UE select for UE ACK/NACK send resource in one, these resources be mapped to constitute for Multiple CCE of the downlink control channel of each UE, and perform ACK/NACK transmission by selected resource.Can be at base Under the agreement stood and previously reached between UE, base station and UE common identification select the resource for UE ACK/NACK transmission Method.For a possible example, there is such a method: control letter for the downlink that will be mapped to constituting UE The ACK/NACK resource of the CCE in the CCE in road with minimum index is set to UE and is actually used in the resource that ACK/NACK sends.Cause This, in fig. 8 a in example illustrated, UE#1 uses and is mapped to ACK/NACK resource OS (0) of CCE (0), CS (0) and RB (0) Send ACK/NACK；UE#2 uses and is mapped to ACK/NACK resource OS (0) of CCE (4), CS (4) and RB (0) transmission ACK/ NACK；And UE#3 uses and is mapped to ACK/NACK resource OS (1) of CCE (6), CS (0) and RB (0) transmission ACK/NACK.
Fig. 8 B illustrates following example: CCE (0), CCE (3), CCE (6) and CCE (7) composition and includes the scheduling for UE#1 The downlink control channel of control information；CCE (1) and CCE (4) composition includes the descending of the scheduling control information for UE#2 Link control channel；And CCE (2) and CCE (5) constitutes the downlink control letter including the scheduling control information for UE#3 Road.
There is such a method: be used for will be mapped to, in constituting the CCE of down control channel of UE, there is minimum rope The ACK/NACK resource of the CCE drawn is set to UE and is actually used in the resource that ACK/NACK sends.In this case, in the fig. 8b In example illustrated, UE#1 uses and is mapped to ACK/NACK resource OS (0) of CCE (0), CS (0) and RB (0) transmission ACK/ NACK；UE#2 uses and is mapped to ACK/NACK resource OS (0) of CCE (1), CS (1) and RB (0) transmission ACK/NACK；And UE# 3 uses are mapped to ACK/NACK resource OS (0) of CCE (2), CS (2) and RB (0) and send ACK/NACK.
It addition, in addition to the operation of formula based on embodiment 2 (2), it is also possible to by application equation below (3), Be given for by N altogetherCCEIndividual CCE is mapped to the regular definition of the resource sent for ACK/NACK one to one.Following public affairs Formula (3) is based on the hypothesis that ACK/NACK is only mapped to the RB sending distribution into ACK/NACK.It is to say, do not consider all Other control information of control information as relevant in CQI or MIMO feedback etc are multiplexed into the feelings in identical RB with ACK/NACK Condition.Give N further belowCSTDefinition.
CCE (k) → OS (m), CS (n), RB (o),
K=0,1 ..., NCCE-1
NCST=CEIL (Ncce/NOS)
M=floor (k/Ncst) mod NOS(m=0,1 ..., NOS-1)
N=k mod NCS(n=0,1 ..., NCS-1)
O=floor ((k mod NOS)/NCS) (3)
In superincumbent formula (3), CEIL (x) is no less than the smallest positive integral of x.
Such as, if it is assumed that NRB=2, NCS=6, NOS=3, NCST=8 and NCCE=24, then CCE (k) is reflected one to one It is mapped to resource OS (m), CS (n) and the RB (o) sent for ACK/NACK, as follows.
CCE (0) → OS (0), CS (0), RB (0),
CCE (1) → OS (0), CS (1), RB (0),
CCE (2) → OS (0), CS (2), RB (0),
CCE (3) → OS (0), CS (3), RB (0),
CCE (4) → OS (0), CS (4), RB (0),
CCE (5) → OS (0), CS (5), RB (0),
CCE (6) → OS (0), CS (0), RB (1),
CCE (7) → OS (0), CS (1), RB (1),
CCE (8) → OS (1), CS (0), RB (0)
CCE (9) → OS (1), CS (1), RB (0)
In the above example, if being mapped to the N in the resource that ACK/NACK sends of CCECS=6 predistribution Cyclic shift resource for CCE (0) until CCE (5) all uses up, then CCE (6) is such as mapped to and sends out for ACK/NACK Send cyclic shift CS (0) and the orthogonal sequence OS (0) of distributed the i.e. RB of the 2nd RB (1).For until CCE (7), completing it To NCSTThe mapping of=8 or less the resources sent for ACK/NACK, and return to CCE (8), map it at RB (0) there is no cyclic shift CS (0) and the orthogonal sequence OS (1) used in.By this method, ACK/NACK is mapped to CCE, with Prevent the deterioration of the ACK/NACK receptivity caused due to the loss of orthogonality of orthogonal sequence.
Embodiment 3
Embodiment 3 provides following method: provided and for UE ACK/NACK by downlink control channel in base station In the case of the relevant information of resource sent, change by increasing along with the CCE indexed sequential of downlink control channel Cyclic shift value in the index of orthogonal sequence in the resource that UE ACK/NACK sends and Zadoff-Chu sequence Mode, is mapped to the resource sent for ACK/NACK by CCE.
Fig. 9 A and Fig. 9 B illustrates downlink control channel and the mapping between the resource that UE ACK/NACK sends Relation.The resource sent for ACK/NACK includes: RB information RB (o) (wherein o=0,1 ..., NRB-1), it is frequency domain resource Information；Circular shift information CS (n) (wherein n=0,1 ..., NCS-1), represent that Zadoff-Chu sequence cyclic shift is how many Individual sampling；And orthogonal sequence information OS (m) (wherein m=0,1 ... NOS-1).Assume to be assigned with in systems: for ACK/ NACK sends the N altogether of distributionRRIndividual RB, the N altogether of Zadoff-Chu sequenceCSIndividual cyclic shift value and altogether NOSIndividual orthogonal Sequence.
Fig. 9 A and Fig. 9 B illustrates following method: by fixing use preferential in the resource that UE ACK/NACK sends In the index o of the RB information that ACK/NACK sends, and sequentially increase and order along with the CCE of downlink control channel indexes k The index n of the circular shift information of the index m increasing orthogonal sequence information and the cyclic shift value representing Zadoff-Chu sequence, CCE is mapped to one to one the resource sent for ACK/NACK.In order to keep mapping relations one to one, m can will be indexed Or the mapping ruler between index n with CCE mixes.If a RB acceptable orthogonal sequence letter sent for ACK/NACK The index n of the circular shift information of the index m of breath and the cyclic shift value of expression Zadoff-Chu sequence all uses up, then originally The index o being used for the RB information that ACK/NACK sends is increased by 1 by method, the most again repeats operation.
Formula below (4) can be used to express in this way by N altogetherCCEIndividual CCE is mapped to one to one for ACK/NACK The rule of the resource sent.
CCE (k) → OS (m), CS (n), RB (o),
K=0,1 ..., NCCE-1
M=k mod NOS(m=0,1 ..., NOS-1)
N=k+floor (k/NCS)mod NCS(n=0,1 ..., NCS-1)
O=floor (k/ (NOS*NCS)) (o=0,1 ..., NRB-1) (4)
In superincumbent formula (4), the remainder that " x mod y " expression x obtains divided by y, and floor (z) is little Maximum integer in z.
In order to simplify description, if it is assumed that N in Fig. 9 A and Fig. 9 BRB=1, NCS=6 and NOS=3, then by CCE (k) Resource OS (m), CS (n) and the RB (o) sent for ACK/NACK it is mapped to one, as follows.
CCE (0) → OS (0), CS (0), RB (0),
CCE (1) → OS (1), CS (1), RB (0),
CCE (2) → OS (2), CS (2), RB (0),
CCE (3) → OS (0), CS (3), RB (0),
CCE (4) → OS (1), CS (4), RB (0),
CCE (5) → OS (2), CS (5), RB (0),
CCE (6) → OS (0), CS (1), RB (0),
CCE (7) → OS (1), CS (2), RB (0),
When multiple CCE constitute downlink control channel, CCE can be continuous print, or can be scattered, namely Discontinuous, this depends on that system operates.Fig. 9 A illustrates the previous case, and Fig. 9 B illustrates latter event.
Fig. 9 A illustrates following example: CCE (0), CCE (1), CCE (2) and CCE (3) composition and includes the scheduling for UE#1 The downlink control channel of control information；CCE (4) and CCE (5) composition includes the descending of the scheduling control information for UE#2 Link control channel；And CCE (6) and CCE (7) constitutes the downlink control letter including the scheduling control information for UE#3 Road.
Because UE needs only to send one in response to the data channel sent by base station and downlink control channel ACK/NACK, so UE selects in the resource that UE ACK/NACK sends, these resources are mapped to constitute each Multiple CCE of the downlink control channel of UE, and perform ACK/NACK transmission by selected resource.Base station and UE it Between under the agreement previously reached, the method that can be selected, by base station and UE common identification, the resource sent for UE ACK/NACK. For a possible example, there is such a method: for will be mapped at the downlink control channel constituting UE The ACK/NACK resource of the CCE in CCE with minimum index is set to UE and is actually used in the resource that ACK/NACK sends.Therefore, In figure 9 a in example illustrated, UE#1 uses and is mapped to ACK/NACK resource OS (0) of CCE (0), CS (0) and RB (0) transmission ACK/NACK；UE#2 uses and is mapped to ACK/NACK resource OS (1) of CCE (4), CS (4) and RB (0) transmission ACK/NACK；With And UE#3 uses and is mapped to ACK/NACK resource OS (0) of CCE (6), CS (1) and RB (0) transmission ACK/NACK.
Fig. 9 B illustrates following example: CCE (0), CCE (3), CCE (6) and CCE (7) composition and includes the scheduling for UE#1 The downlink control channel of control information；CCE (1) and CCE (4) constitute UE#2 include for scheduling control information descending Link control channel；And CCE (2) and CCE (5) constitutes the downlink control letter including the scheduling control information for UE#3 Road.
There is a kind of such method: be used for will be mapped to, in constituting the CCE of down control channel of UE, there is minimum The ACK/NACK resource of the CCE of index is set to UE and is actually used in the resource that ACK/NACK sends.In this case, at Fig. 9 B In middle example illustrated, UE#1 uses and is mapped to ACK/NACK resource OS (0) of CCE (0), CS (0) and RB (0) transmission ACK/ NACK；UE#2 uses and is mapped to ACK/NACK resource OS (1) of CCE (1), CS (1) and RB (0) transmission ACK/NACK；And UE# 3 uses are mapped to ACK/NACK resource OS (2) of CCE (2), CS (2) and RB (0) and send ACK/NACK.
Embodiment 3a
Embodiment 3a provides following method: provided and for UE ACK/ by downlink control channel in base station In the case of the relevant information of resource that NACK sends, by increasing along with the CCE indexed sequential of downlink control channel Change in the index of the orthogonal sequence in the resource that UE ACK/NACK sends and Zadoff-Chu sequence according to preassigned pattern Cyclic shift value, CCE is mapped to for ACK/NACK send resource.Embodiment 3a is particularly well-suited to when being wirelessly transferred The when that the maximum delay extension in path being the biggest.
Figure 10 A and Figure 10 B illustrates downlink control channel and reflecting between the resource that UE ACK/NACK sends Penetrate relation.The resource sent for ACK/NACK includes: RB information RB (o) (wherein o=0,1 ..., NRB-1), it is frequency domain money Source information；Circular shift information CS (n) (wherein n=0,1 ..., NCS-1), represent many for Zadoff-Chu sequence cyclic shift Few sampling；And orthogonal sequence information OS (m) (wherein m=0,1 ... NOS-1).Assume to be assigned with in systems as ACK/ NACK sends the N altogether of distributionRBIndividual RB, is assigned with the total of Zadoff-Chu sequence in the RB sent for ACK/NACK N altogetherCSIndividual cyclic shift value, and it is assigned with N altogether in the RB sent for ACK/NACKOSIndividual orthogonal sequence.
Figure 10 A and Figure 10 B illustrates following method: by preferentially fixing in the resource that UE ACK/NACK sends The index o of RB information sent for ACK/NACK, and along with the CCE of downlink control channel index k sequentially increase and Sequentially increase the index n of the circular shift information of Zadoff-Chu sequence after the index m of extra fixing orthogonal sequence information, come CCE is mapped to one to one the resource sent for ACK/NACK.In this case, this method is according to orthogonal sequence information Index m changes the circular shift information of the Zadoff-Chu sequence represented by index n, and makes to be mapped to given cyclic shift value The number of orthogonal sequence minimize, so that the minimum interference between orthogonal sequence.Table 1 shows for ACK/NACK The circular shift information of Zadoff-Chu sequence that sends for ACK/NACK in the RB sent and orthogonal sequence information Example.
Table 1
In the environment that the maximum delay with the biggest wireless propagation path extends, the mapping scheme of table 1 is by allowing The cyclic shift value of Zadoff-Chu sequence sent for ACK/NACK has longer 3 sampling interval and prevents orthogonality Deterioration, and eliminate orthogonal sequence by the given cyclic shift value that orthogonal sequence is mapped to one to one Zadoff-Chu sequence Interference between row.In Table 1, by being defined as the circular shift information of Zadoff-Chu sequence and orthogonal sequence information The resource of combination sends ACK/NACK#1-ACK/NACK#11, and most 12 ack/nack signals can be with ACK/ NACK#1, ACK/NACK2 ..., the order of ACK/NACK#11 are sequentially multiplexed in a RB.
If after securing the index o of RB information and the index m of orthogonal sequence information sent for ACK/NACK, The index of the circular shift information of Zadoff-Chu sequence is all used up, then the index m of orthogonal sequence information is increased by this programme Add 1, be then back to from the index starting to sequentially increase the circular shift information of the cyclic shift value representing Zadoff-Chu sequence. If repeating after operation above, the index m of orthogonal sequence information uses up, then this method will be used for ACK/NACK The index o of the RB information sent increases by 1, the most again repeats operation.Generally, base station distribute on the basis of semi-quiescent and The RB that management sends for ACK/NACK, and exist as follows may situation: locate at any time, distributed for ACK/ In the RB that NACK sends, only only a part sends for ACK/NACK.In this case, those distribution can be used for by base station ACK/NACK sends but the actual RB sent not used for ACK/NACK is scheduling to resource for another purpose, such as, adjusts Degree is the resource sent for UE data.
Can be by like fashion by N altogetherCCEIndividual CCE is mapped to the rule of the resource sent for ACK/NACK one to one It is expressed as follows.Under the hypothesis that only ACK/NACK is mapped to the RB sending distribution into ACK/NACK, preset equation below (5).It is to say, in order to simplify description, do not consider other controls of control information relevant for such as CQI or MIMO feedback etc Information processed and ACK/NACK are multiplexed into the situation in identical RB.

N=k mod NCS(n=0,1 ..., NCS-1)
O=floor (k/ (NOS*NCS)) (o=0,1 ..., NRB-1) (5)
In superincumbent formula (5), the remainder that " x mod y " expression x obtains divided by y, and floor (z) is little Maximum integer in z.
In order to simplify description, if it is assumed that N in Figure 10 A and Figure 10 BRB=1, NCS=4 and NOS=3, then by CCE (k) It is mapped to resource OS (m), CS (n) and the RB (o) sent for ACK/NACK one to one, as follows.
CCE (0) → OS (0), CS (0,0), RB (0),
CCE (1) → OS (0), CS (0,1), RB (0),
CCE (2) → OS (0), CS (0,2), RB (0),
CCE (3) → OS (0), CS (0,3), RB (0),
CCE (4) → OS (1), CS (1,0), RB (0),
CCE (5) → OS (1), CS (1,1), RB (0),
CCE (6) → OS (1), CS (1,2), RB (0),
CCE (7) → OS (1), CS (1,3), RB (0),
CCE (8) → OS (2), CS (2,0), RB (0),
CCE (9) → OS (2), CS (2,1), RB (0),
CCE (10) → OS (2), CS (2,2), RB (0),
CCE (11) → OS (2), CS (2,3), RB (0) ...
When multiple CCE constitute downlink control channel, CCE can be continuous print, or can be scattered, namely Discontinuous, this depends on that system operates.Figure 10 A illustrates the previous case, and Figure 10 B illustrates latter event.
Figure 10 A illustrates following example: CCE (0), CCE (1), CCE (2) and CCE (3) composition and includes the tune for UE#1 The downlink control channel of degree control information；CCE (4) and CCE (5) composition includes under the scheduling control information of UE#2 Uplink Control Channel；CCE (6) and CCE (7) constitutes the downlink control letter including the scheduling control information for UE#3 Road；CCE (8) and CCE (9) constitutes the downlink control channel including the scheduling control information for UE#4；And CCE (10) The downlink control channel including the scheduling control information for UE#5 is constituted with CCE (11).
Because UE needs only to send one in response to the data channel sent by base station and downlink control channel ACK/NACK, so UE selects in the resource that UE ACK/NACK sends, these resources are mapped to constitute each Multiple CCE of the downlink control channel of UE, and perform ACK/NACK transmission by selected resource.Base station and UE it Between under the agreement previously reached, the method that can be selected, by base station and UE common identification, the resource sent for UE ACK/NACK. For possible example, exist and a kind of have in constituting the CCE of downlink control channel of UE for will be mapped to The ACK/NACK resource of the CCE of minimum index is set to the method that UE is actually used in the resource that ACK/NACK sends.Therefore, at figure In 10A in example illustrated, UE#1 uses and is mapped to ACK/NACK resource OS (0) of CCE (0), CS (0,0) and RB (0) transmission ACK/NACK；UE#2 uses and is mapped to ACK/NACK resource OS (1) of CCE (4), CS (1,0) and RB (0) transmission ACK/NACK； UE#3 uses and is mapped to ACK/NACK resource OS (1) of CCE (6), CS (1,2) and RB (0) transmission ACK/NACK；UE#4 uses and reflects It is mapped to ACK/NACK resource OS (2) of CCE (8), CS (2,0) and RB (0) and sends ACK/NACK；And UE#5 uses and is mapped to ACK/NACK resource OS (2) of CCE (10), CS (2,2) and RB (0) send ACK/NACK.
Figure 10 B illustrates following example: wherein, CCE (0), CCE (5), CCE (10) and CCE (11) constitute include for The downlink control channel of the scheduling control information of UE#1；CCE (1) and CCE (6) composition includes the scheduling controlling for UE#2 The downlink control channel of information；CCE (2) and CCE (7) constitutes the downlink including the scheduling control information for UE#3 Control channel；CCE (3) and CCE (8) constitutes the downlink control channel including the scheduling control information for UE#4；And CCE (4) and CCE (9) constitutes the downlink control channel including the scheduling control information for UE#5.
Have a kind of CCE's for will be mapped to have minimum index in constituting the CCE of down control channel of UE ACK/NACK resource is set to the method that UE is actually used in the resource that ACK/NACK sends.In this case, scheme in fig. 1 ob In the example shown, UE#1 uses and is mapped to ACK/NACK resource OS (0) of CCE (0), CS (0,0) and RB (0) transmission ACK/ NACK；UE#2 uses and is mapped to ACK/NACK resource OS (0) of CCE (1), CS (0,1) and RB (0) transmission ACK/NACK；UE#3 Use is mapped to ACK/NACK resource OS (0) of CCE (2), CS (0,2) and RB (0) and sends ACK/NACK；UE#4 uses and is mapped to ACK/NACK resource OS (0) of CCE (3), CS (0,3) and RB (0) send ACK/NACK；And UE#5 uses and is mapped to CCE (4) ACK/NACK resource OS (1), CS (1,0) and RB (0) send ACK/NACK.
Embodiment 4
Embodiment 4 provides following operation: optionally by an application in embodiment 1, embodiment 2 and embodiment 3 Distribution and relevant signaling information thereof in the resource sent for UE ACK/NACK.
Base station sends following control information to UE, in order to the resource that effectively management sends for UE ACK/NACK.
