Preferably, upstream components carrier wave provides downlink transmission to feed back for multiple downlink component carrier.
Such as: multiple downlink component carrier and a upstream components carrier wave are associated, so the base station (eNB) of this embodiment retains PUCCHspace respectively for multiple DLCC on this ULCC.Wherein PUCCHspace can be frequency division, the resource that time-division or code divide, use the computing formula of 3GPPR8 specification can obtain this PUCCHspace, association herein refers to that upstream components carrier wave x (ULCCx) provides feedback for the DLassignment on DLCCx (downlink component carrier x), and ULCCx is that this DLCCx retains feedback resources.
Describe multiple preferred embodiment of the present invention below again, these preferred embodiments combine the technical scheme of multiple preferred embodiment above.
Preferred embodiment one
In the present embodiment, when UE is resident, system message collocation method can be used to configure PUCCHspace; When UE accesses, indicate PUCCHspace by wireless heterogeneous networks (RadioResourceControl, referred to as RRC) signaling.
Fig. 2 is the flow chart of the configuration PUCCHspace according to the embodiment of the present invention.As shown in Figure 2, following step is comprised:
Step S201, UE persistent district, the component carrier of place PUCCH is DLCCx, and wherein x is component carrier mark.
Step S202, UE receiving system information, the component carrier of feeding back ACK/NACK such as, is indicated to be ULCCx in SIB-2, wherein x is component carrier label, then component carrier space is PUCCHspacexx, wherein the previous x of spacexx is component carrier mark in DLCCx, and a rear x is component carrier mark in DLCCx.
Preferably, in step S202, the carrier wave that UE is resident, can use system message collocation method to configure PUCCHspace.Particularly, select or cell reselection through community, UE resides in certain suitable cell being positioned at accessible carrier wave DLCC0, the upstream components carrier wave ULCC0 at the feedback space place of this DLCC0 is determined by system message System information block 2 (SystemInformationBlock, referred to as SIB2).Then note is positioned at the feedback space of DLCC0 on component carrier ULCC0 is PUCCHspace00, UE calculates the pertinent system information parameter of PUCCHspace00 by reading, as Release8, parameter leaves cell PUCCH-ConfigCommon in, namely uses the algorithm of PUCCH-ConfigCommon and Release8 to calculate PUCCHspace00.
Step S203, UE access base station (eNB), eNB is that component carrier DLCCy is joined in UE increasing, and wherein y is component carrier mark.
Step S204, whether the component carrier in determining step S203 is PDCCHDLCC.
Step S205, if judged result is no, then eNB is not for DLCCy configures PUCCHspace.
Preferably, for UE, when eNB joins DLCC1 by RRC signaling for this UE increases, if this DLCC1 is non-PDCCHDLCC, so not for this non-PDCCHDLCC indicates ULCC and PUCCHspace of association.
It should be noted that, " association " in this enforcement refers to that this ULCCx (upstream components carrier wave x) provides feedback for the DLassignment on DLCCx (downlink component carrier x), and ULCCx is that this DLCCx retains feedback resources.
Whether step S206, the PUCCHspace in determining step S205 are accessible DLCC.
Step S207, judged result is no, then eNB configures ULCCy (y is the mark of component carrier) in RRC signaling, and configures PUCCHspaceyy.
Step S208, judged result is accessible downlink component carrier, then eNB configures ULCCy (y is component carrier label) in RRC signaling, and configures PUCCHspaceyy, or UE configures ULCCy from the system information of DLCCy, and configures PUCCHspaceyy.
In above-mentioned steps S207 and step S208, for UE, when eNB joins DLCC1 by RRC signaling for this UE increases, if this DLCC1 is PDCCHDLCC, then eNB indicates PUCCHspace for this PDCCHDLCC.If this PDCCHDLCC is accessible DLCC, the step in step S202 so can be adopted to indicate PUCCHspace, RRC signaling in step S208 also can be adopted to indicate PUCCHspace.If PDCCHDLCC is the DLCC that not can be accessed by, RRC signaling so can only be adopted to indicate PUCCHspace.
Step S209, configuration terminates.
In the present embodiment, achieve the configuration to PUCCHspace, being divided into UE persistent district and access two kinds of situations, system message when wherein UE is resident, can be adopted to indicate PUCCHspace, system message can be adopted when accessing to indicate or RRC signaling instruction PUCCHspace.

Step S308, UE physical layer is from downlink data receiving the DLCC indicated by CIF and be demodulated into transmission block (Transportblock, referred to as TB).
Step S310, UE physical layer from this carrier wave DLCCx downlink data receiving, and is demodulated into TB.
The physical layer of step S312, UE extracts HARQinformation by DLassisgnment, and it is completely the same that HARQinformation no longer comprises CIF and R8 agreement, and the TB after demodulation sends to the HARQMACentityx process corresponding to DLCCx.
Step S314, HARQMACentityx process according to the specification of R8: judge new biography, old biography, HARQInformation and TB are sent to the HARQprocess process of HARQprocessID indication in HARQInformation.
Step S316, pass if first, directly cover the HARQprocessbuffer corresponding to HARQprocessID, if retransmit, be then placed in this HARQprocessbuffer after the data comprised with the HARQprocessbuffer corresponding to HARQprocessID merge.
The information such as the MCS that HARQInformation comprises by step S318, HARQprocess, as parameter call physical layer decode procedure, are decoded to HARQprocessbuffer.
Step S320, judges that whether decoding is successful.
Step S322, judged result is yes, and the PUCCHspacexx on the ULCCx associated by PDCCHDLCCx sends ACK.
Step S322, judged result is no, and the PUCCHspacexx on the ULCCx associated by PDCCHDLCCx sends NACK.
Achieve the feedback to downlink transmission on PUCCHspace in the present embodiment, have employed unified mode for across carrier dispatching and the non-downlink transfer across carrier dispatching, the HARQ downlink transfer of complete compatible R8/R9 (version 8/9).
