At the time requirement in the UE realization, standard discussion at present determines, UE receives the MAC signaling of activation CC at subframe n, need finish the operation of corresponding C C activation in n+8 subframe the latest.Simultaneously, standard code is not carried out following operation at UE on the deexcitation carrier wave: (1) UE on the deexcitation descending carrier does not monitor PDCCH; (2) to the deexcitation descending carrier, UE does not carry out CSI and measures, and does not feed back CSI yet; (3) UE does not send the SRS signal on the up-link carrier of deexcitation; (4) to the up-link carrier of deexcitation, UE does not carry out PHR(Power Headroom Reporting, power headroom reporting) report.
In addition, for the FDD system, UE receives the PDSCH(Physical Downlink Shared Channel that the base station sends at subframe m, Physical Downlink Shared Channel), to be fixed on subframe m+4 and carry out ACK(Acknowledge Character, acknowledge character)/and NACK(Negative Acknowledgment, negative acknowledge character) feedback.
For the TDD system, if UE receives the PDSCH that the base station sends in subframe N-K, need in subframe N, carry out corresponding ACK/NACK feedback, the value of K be by the UL-DL(of TDD up-descending) configuration(configuration) with the common decision of numbering of feedback subframe n, as shown in table 1, be corresponding relation between the numbering of different uplink-downlink configuration downlink data transmission subframes and uplink ACK/NACK feedback subframe n.

As shown in Figure 2, be the frame structure of LTE TDD system, a radio frames length is 10ms, comprises special subframe and conventional subframe two classes totally 10 subframes, and each subframe is 1ms.Special subframe is divided into 3 time slot: DwPTS(and is used to transmit PSS/PDCCH/PHICH(Physical HARQ Indication Channel; the physical mixed automatic re-transmission indicating channel)/PCFICH(Physical Control Format Indicator Channel; Physical Control Format Indicator Channel)/PDSCH etc.), GP(be used between descending and up protection at interval) and UpPTS(be used for transmitting SRS/PRACH(Packet Random Access Channel, Packet Random Access Channel) etc.).
In addition, conventional subframe comprises sub-frame of uplink and descending sub frame, is used to transmit up/descending control signaling and business datum etc.Wherein in a radio frames, can dispose two special subframes (being positioned at subframe #1 and #6), also can dispose a special subframe (being positioned at subframe #1); Always as downlink transfer, the UpPTS time slot in subframe #2 and the special subframe always is used for uplink to DwPTS time slot in subframe #0 and subframe #5 and the special subframe, and other subframes can be configured to as uplink or downlink transfer according to needs.
It should be noted that the ascending-descending subframes distribution can be supported 7 kinds of different modes among the TD-LTE, the concrete configuration parameter is as shown in table 2, D represents as downlink transfer, U represents that S represents that this subframe is a special subframe as uplink, and table 2 comprises DwPTS, GP and UpPTS three parts.
Table 2 LTE TDD ascending-descending subframes configuration format
In LTE Rel-10 system, the mechanism of definition UE quick active/deexcitation carrier wave (activate/deactive CC), and regulation UE only monitors PDCCH in the descending carrier (activated DL CC) that activates, and only sends the SRS signal in the up-link carrier (activated UL CC) that activates.Because the activation carrier wave is to be notified to UE's by base stations control and by the special-purpose MAC CE that is carried on the PDSCH, in the activation signalling interactive process, the problem that may exist base station and UE that the carrier wave of concrete activation is understood differently and causes, thus data transmit-receive mistake between base station and the UE caused.Existing solution has only solved the problem of FDD system, can not be applicable to the TDD system.
Concrete, in the LTE-A carrier aggregation system, send the activation signaling from the base station, to base station feedback ACK/NACK information and finish in the time period of carrier wave activation, may there be inconsistent situation in base station and UE for the understanding that CSI feeds back to UE.For example, the base station has sent the activation signaling in carrier wave n, and UE carries out the ACK/NACK feedback at subframe n+4 to the base station, and finishes the operation of carrier wave activation in n+8, and concrete time span is relevant with the UE disposal ability; The base station receives also to be needed can know whether UE has correctly received reconfiguration information behind certain processing delay after UE feeds back, then during this period of time, and the concrete configuration situation of the CSI that the uncertain UE in base station is fed back.
With TDD uplink-downlink configuration in the table 10 is example, if send the MAC CE of activation in the subframe 1 of base station in radio frames N, then UE need just can carry out ACK/NACK feedback (k=6 this moment) in subframe 7, make the subframe 1 of base station in radio frames N+1 just can finish the decoding of this ACK/NACK information, and the subframe 9 of UE reality in radio frames N finished the adjustment of activation corresponding apparatus.Then make subframe 9 at radio frames N to having formed base station and UE between the subframe 1 of radio frames N+1, may cause signal transmitting and receiving mistake between the two the inconsistent understanding that active set of carriers closes.
At the problems referred to above, the embodiment of the invention provides data processing method and the equipment under a kind of carrier aggregation system, by timing relationship reasonable in design, makes the TDD system base-station consistent to the understanding that activates carrier wave with UE, avoids mistake.
Below in conjunction with the accompanying drawing among the present invention, the technical scheme among the present invention is clearly and completely described, obviously, described embodiment only is a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
