Description
Technical field
The present invention relates to the communications field, more specifically, relate to the time division duplex configuration in carrier aggregation (CA).
Background technology
Carrier aggregation technology is a key property of senior Long Term Evolution (LTE-Advanced) standard, is also to realizeThe key technology of LTE-Advanced system 100,000,000 bandwidth operations, but it has also brought many to LTE-Advanced air protocolChallenge. In order to support carrier aggregation technology, LTE-Advanced need to carry out many-sided increasing to LTE air protocol before thisBy force.
LTE-Advanced requires to provide descending 1Gbit/s, the peak value speed of up 500Mbit/s in the bandwidth of 100MHzRate. In order to work in so wide bandwidth, LTE-Advanced has introduced carrier aggregation technology. Carrier aggregation can be by wholeClosing several discrete frequency bands is UE service jointly. Consider and the backwards compatibility of LTE, LTE-Advanced has introduced memberThe concept of carrier wave, the maximum bandwidth of each member carrier is no more than 20MHz, i.e. 110 RB. LTE-Advanced air protocol isBased on LTE air protocol. Unlike in LTE, each community only has a member carrier, and each UE also only has a member to carryRipple (CC) is its service, and in LTE-Advanced, there are multiple member carriers each community, and each UE also may have multiple membersCarrier wave is its service, and therefore LTE-Advanced need to strengthen LTE air protocol in many-side.
Carrier aggregation comprises time division duplex (TDD) and FDD (FDD), and the two is all supported between the interior polymerization of frequency band and frequency bandPolymerization. TDD is asymmetrical UL-DL configuration with respect to an advantage of FDD. For carrier aggregation between frequency band, member carrierThe TDD configuration of specific (CC is specific) can provide resource more flexibly to use, and further realizes more by flow adaptationHigh frequency efficiency.
3GPPTS36.331V10.1.0 (Rel-10) described the specification of identical frequency band intercarrier polymerization, Qi ZhongcongThe angle of subscriber equipment, ack/nack (ACK/NACK) message only allows at main plot (Pcell) on send.If but this frequency band intercarrier polymerization specification is applied to carrier aggregation between frequency band, and there will be following problem: 1) up-link/Downlink (UL/DL) interference problem, it can ignore in polymerization between frequency band, because exist between two frequency bands greatlyGuard band; 2) the specific TDD configuration of CC will exert an influence to control signal.
Fig. 1 shows the schematic diagram for the problem of the ACK/NACK sequential of carrier aggregation between frequency band. Under D wherein representsUplink subframe, U represents uplink sub-frames, S represents special subframe, it has 3 territories, be respectively DwPTS, GP andUpPTS。
As shown in Figure 1, for the downlink PDSCH transmission on subframe #0, the ACK/NACK feedback of Scell is positioned at sonFrame #4 is upper, and ACK/NACK feedback corresponding to Pcell is positioned on subframe #7. This means, for identical DL subframe, it is correspondingUL feedback subframe on different aggregation cell, be different. And in the frequency band intercarrier polymerization of supporting at Rel-10, andDo not distinguish this difference on Pcell and Scell. That is to say, UE thinks that the configuration of Pcell and the configuration of Scell are all the timeIdentical.
As shown in Figure 1, the configuration #1 of Pcell is for example " DSUUDDSUUD ", and the configuration #0 of Scell is for example" DSUUUDSUUU ". According to the principle of Rel-10 midband intercarrier polymerization, UE has identical by hypothesis Scell and PcellConfiguration, that is to say, thinks that the #4 of Scell and #9 work song frame are for downlink transmission. Therefore, UE will be at #4 and #9 work song framePlace waits for DL data. But as can be seen from Figure 1, these two subframes are actually for ul transmissions, thereforeENB is by can not be in these two any downlink transmission of subframe rise degree.
Fig. 2 has provided a solution for the problems referred to above. In Fig. 2, eNB can be by the #4 of Scell and No. #9Subframe shields, thereby makes it for example become empty subframe or be called " pseudo-UL ". This solution is " thoroughly for UEBright ".
Although the solution shown in Fig. 2 is very little for existing technical specification impact, it has following seriousDefect.
One of target of the specific TDD configuration of member carrier is to realize high performance gains by business adaptation, and frequentlyIn interband carrier aggregation, the particular frame of Scell is masked and will cause bandwidth waste and reduce the flexibility of dispatching. In " puppet "In the situation of UL, the ACK/NACK of the DL transfer of data of Scell is processed by Pcell at first. Other UL transmission, for exampleCQI, SRS, PUSCH etc., be semi-static configuration or by Event triggered, and can realize flexibly at eNB placeScheduling/configuration, therefore the impact of " puppet " UL is smaller. But, the in the situation that of " puppet " DL, will there will be some and common referenceThe problem of signal (CRS) and the problem of ACK/NACK correlated process. This is because hypothesis CRS is present in those " puppets " DL by UEIn subframe. In order to address this problem, can adopt the similar principle of Rel-10TDMeICIC, wherein for UE has defined two sonsThe subframe of group is measured to carry out. For the ACK/NACK feedback in FDDeICIC, in the time that DL subframe is masked, correspondingPUSCH transmission (example is 4 subframes as in the previous) also will be cancelled. Distribute for TDDUL-DL, ACK/NACK timing moreComplexity, and in addition, can reply multiple UL subframes by single DL subframe. Therefore, by corresponding ULPUSCH transmission screenCover and will further reduce efficiency of transmission.
That in Rel-10, supports in addition, also will run into new problem across carrier dispatching. For example, adjust across carrier wave by PcellThe subframe that is scheduled (for example UL subframe) in the Scell of degree may for example, clash with the actual TDD configuration (DL) of Scell.Therefore, between frequency band, in carrier aggregation, using the frequency band intercarrier polymerization of supporting in Rel-10 is not a kind of solution of satisfactionScheme.
For this problem, need a kind of scheme to replace above-mentioned " transparent " solution, clearly by Scell'sTDD configuration notification, to UE, uses thereby can realize full bandwidth

Detailed description of the invention
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing. It is pointed out that the present invention is usingFamily equipment (UE) and Node B, for example, transmit between evolved Node B (eNb). UE is called uplink to the communication of eNbRoad transmission, and eNb is called downlink transmission to the communication of UE.
Fig. 3 shows according to the flow chart of the method for one aspect of the invention. As shown in Figure 3, according to one of the present inventionAspect, provides a kind of method 100 using in carrier aggregation between frequency band comprising Pcell He Cong community, main plot Scell, shouldMethod 100 comprises: in step 110, receive the first information of the TDD configuration that represents Pcell; In step 120, receiveRepresent the second information of the TDD configuration of Scell; In step 130, according to the described first information and the second information send confirmation/NACK ACK/NACK message. It will be appreciated that, the method 100 can be carried out at UE place.
As previously mentioned, in the prior art, UE is identical by the TDD of Pcell and Scell configuration is thought all the time, orPerson UE ignores the TDD configuration of Scell and only configures to carry out the transmission of for example ACK/NACK according to the TDD of Pcell, thus canCan cause the shortcomings such as bandwidth waste. But according to an exemplary embodiment of the present invention, UE will know Scell clearlyTDD configuration, and in carrying out ACK/NACK transmission according to the two TDD configuration of Pcell and Scell, and not onlyTDD with Pcell is configured to foundation. Thereby once the configuration of Scell changes, UE can be known this change.
The second information that receives the TDD configuration that represents Scell can be carried out in many ways. According to one of the present inventionIllustrative embodiments, the second information that receives the TDD configuration that represents Scell can comprise receiving system from described ScellBlock of information (SIB) information, described SIB information comprises the second information of the TDD configuration that represents Scell. With having in rel-10 beThe member carrier of the system TDD configuration difference that condenses together, in Rel-11, if support member to carry between frequency band in carrier aggregationThe specific TDD configuration of ripple, and if the TDD of the Pcell that UE obtains and Scell configuration is different, needs to pre-determine at thisWhether the Tdd configuration for Scell in situation is effective. According to the embodiment of the present invention, the rule of UE employing of the present invention is: asThe TDD configuration of fruit Scell is different from the TDD configuration of Pcell, thinks the invalid configuration of Pcell.
According to another implementation of the invention, reception represents that the second information of the TDD configuration of Scell comprises: pass throughSpecific messages receives the second information about the TDD configuration of described Scell. The advantage of this mode is to be joined as ScellWhen putting or reconfigure, UE can obtain the configuration information of Scell at once, thereby knows whether it changes.
The configuration information of each member carrier is notified to the advantage of carrier aggregation between the frequency band of UE and is that resource can obtainTo utilizing completely.
According to an embodiment of the invention, wherein, send ACK/ according to the described first information and the second informationNACK message comprises: will in the TDD configuration of described Scell, be mapped to described Pcell for sending the subframe of ACK/NACK messageTDD configuration in for sending the subframe of ACK/NACK message; And on described Pcell send mapping after ACK/NACKMessage in other words, sends the ACK/NACK message of the member carrier of polymerization on Pcell.
In other words, as an example of the ACK/NACK on uplink direction example (it will be appreciated that, selection up directionIt is only an example that ACK/NACK discusses, and the present invention can pass by the ACK/NACK on oppositely for downlink equallyDefeated), said method is the uplink control channel that the ACK/NACK feedback of polymerization member carrier is only remained on to Pcell(PUCCH) on. In this case, the ACN/NACK mapping of Scell to Pcell proposed, its only need by Scell separately/It is upper that the ACK/NACK of binding is attached to PUCCH/PUSCH, and do not change the transmitting procedure of the ACK/NACK of Pcell.
Different from FDD (FDD), observe when predetermined for the ACK/NACK feedback of TDD downlink transmissionProgram process, as shown in Table 1 below, typically, subframe n will carry DL data burst group { n-km| m=0,1 ..., M-1}'sACK/NACk feedback, and the minimum interval of the PDSCH transmitting and ACK/NACK subframe is for being not less than 4 TTI (subframe).
Table 1
By table 1, can obtain each ACK/NACK under every kind of configuration for subframe numbers. For example for configuration #1,The corresponding numeral of 2 work song frame in its 10 subframes is 7 and 6, now, and 2-(7,6)=(5 ,-4). If the knot obtainingFruit is for negative, adds the sum (10) of subframe, therefore obtains (5,6). Negative sign means that this subframe is in this ACK/NACK instituteIn the former frame of place's frame. That is to say, 2 work song frames are ACK/NACK feedbacks of No. 5 and 6 work song frames in former frame. And for joiningPut #0, for example 4 work song frames are ACK/NACK feedbacks of 0 work song frame in same frame. Referring to Fig. 4, it shows is not applying rootThe exemplary sequential chart of ACK/NACK transmission in Pcell and Scell during according to the mapping of exemplary embodiment of the invention. This exampleProperty sequential chart is followed the rule in above-mentioned table 1.
Can find out referring to Fig. 4 (a), for carrier aggregation between frequency band, owing to not supporting PUCCH in Scell, therefore 0The ACK/NACK of work song frame and 5 work song frames can not correctly be sent.
For with Rel-10 in ACK/NACK feedback procedure be consistent, the present invention proposes new mapping scheme with useCarrier aggregation between the frequency band with different TDD configurations.
Fig. 5 shows the method flow diagram of Scell-Pcell mapping according to one exemplary embodiment.
As shown in Figure 5, according to an exemplary embodiment of the present invention, by the TDD configuration of described Scell for sending outSend in the TDD configuration that the subframe of ACK/NACK message is mapped to described Pcell in the subframe for sending ACK/NACK message and wrapDraw together: in step 131, determine that whether the first frame number in TDD in described Pcell and Scell configuration is all for sending ACK/NACK message; In step 132, if so, the ACK/NACK message maps under the first frame number described in described Scell is arrivedThe first frame number in Pcell; In step 133, if described the first frame number in described Scell is used for sending ACK/NACK messageAnd the first frame number in described Pcell is not used in and sends ACK/NACK message, in Pcell, be identified for as described PcellIn the first frame number the second frame number of ACK/NACK message is provided, then, by the ACK/NACK of the first frame number in described ScellMessage maps is to the second frame number in described Pcell.
And Fig. 4 (b) show in the time having applied mapping according to one exemplary embodiment Pcell andThe exemplary sequential chart of ACK/NACK transmission in Scell. Illustrate the whole flow process of Fig. 5 below as an example of Fig. 4 (b) example.
For the example in Fig. 4 (b), if determine a certain subframe all for sending ACK/NACK message, can byThe ACK/NACK configuring in this Scell is directly attached to UL subframe identical in Pcell and transmits, and can not produce subframe itBetween conflict. For example, as shown in Fig. 4 (b), in Pcell and Scell, the ACK/NACK of No. 0 and 1 work song frame feeds back at 7 work songsIn frame, send, therefore the ACK/NACK in 7 work song frames in Scell can be attached in the 7 work song frames of Pcell and carry outSend. From this example of Fig. 4 (b), can draw such conclusion, for table 1, if having different configurations Pcell andThere is effective k in the subframe row n of Scellm, m=0,1 ..., M-1, the ACK/NACK of the subframe set of Scell can be attachedOr be mapped in the same subframe of carrying ACK/NACK in Pcell.
If described the first frame number in described Scell for send ACK/NACK message and described Pcell firstFrame number is not used in and sends ACK/NACK message, and for example, in Fig. 4 (b), in Scell No. 4 and 9 work song frames are respectively used to send 1Number and the ACK/NACK message (being UL message) of 5 work song frames, disappear and in Pcell No. 4 and 9 work song frames do not send ACK/NACKBreath (because DL message) is identified for providing ACK/NACK message for No. 4 in described Pcell and 9 work song frames in PcellFrame number (being respectively 3 work song frames in 8 work song frames and a rear frame), then, by No. 4 in described Scell and 9 work song framesMiddle ACK/NACK message is shone upon respectively or is attached to 3 work song frames in 8 work song frames and the rear frame in described Pcell, alsoBe to say, the ACK/NACK of No. 0 and the 5th work song frame in Scell be placed on respectively to the 8th work song frame and a rear frame of PcellIn 3 work song frames in carry out.
Fig. 6 shows the method flow diagram of the Scell-Pcell mapping of another illustrative embodiments according to the present invention.
As shown in Figure 6, according to another illustrative embodiments of the present invention, by the TDD configuration of described Scell forThe subframe that sends ACK/NACK message is mapped in the TDD configuration of described Pcell for sending the subframe of ACK/NACK messageComprise: in step 131 ', determine that whether the first frame number in TDD in described Pcell and Scell configuration is all for sending ACK/NACK message; In step 132 ', if so, the ACK/NACK message maps under the first frame number in described Scell is arrived to PcellIn the first frame number; In step 133 ', if described the first frame number in described Scell is used for sending ACK/NACK message and instituteState the first frame number in Pcell and be not used in and send ACK/NACK message, in Pcell, determine with described the first frame number interval notBe less than immediate the second frame number predetermined quantity subframe, that ACK/NACK message is provided, then, by described ScellThe ACK/NACK message maps of one frame number is to the second frame number in described Pcell.
Step 131 in Fig. 6 ' and 132 ' be identical with the step 131 and 132 in Fig. 5 respectively, therefore here will be no longerRepeat.
Step 133 ' be with 133 difference, in step 133 ' in, find qualified immediate frame number and sendACK/NACK message, and in step 133, need to send ACK/NACK message according to pre-specified subframe.
Fig. 4 (c) show in the time having applied according to the present invention the mapping of another illustrative embodiments Pcell andThe exemplary sequential chart of ACK/NACK transmission in Scell. Illustrate the whole flow process of book Fig. 6 below as an example of Fig. 4 (c) example.
For step 131 ' and 132 ', explain for identical step 131 and 132 hereinbefore, hereTo repeat no more.
For step 133 ', feed back not the 3rd work song frame in next frame for the ACK/NACK of the 5th work song frame and enterOK, but carry out in the 2nd work song frame of this next frame because in this next frame 2 work song frames with respect to 3 work song frame pitches from aforementioned5 work song frames nearer. Certainly, be understandable that, between downlink subframe and its corresponding feedback subframe, need to keep oneFixed distance. Preferably, this distance is 4, namely at least apart from 4 subframes (TTI).
Can see, the beneficial effect that such scheme brings is, joins when Pcell and Scell dispose different TDDWhen putting, can realize full bandwidth utilization. In addition, also no longer there is bandwidth waste problem across carrier dispatching. Because UE is definiteThe configuration of any member carrier is known on ground, and therefore eNB can carry out in the case of the ACK/NACK principle that does not change Rel-10Efficient scheduling. In the situation that disposing multiple Scell, can also there be two kinds of solutions. A kind of by each ScellACK/NACK is attached or be mapped on Pcell individually; Another kind of scheme will be owned by logic AND computingThe binding result of the ACK/NACK of Scell is attached or be mapped on Pcell.
It will be appreciated that, although be situated between with the form of method step in conjunction with Fig. 4 (a)-Fig. 4 (c) and Fig. 5 and Fig. 6 aboveContinue and how to have carried out Scell-Pcell mapping. But in fact, the mapping relations of the two can be pre-formed and be one and searchTable, and this look-up table stores is in the memory of UE end or base station end, in the time that needs carry out according to mapping of the present invention,Directly access look-up table. But, in the situation that processing power is enough, also can be immediately at UE place or base station (eNB)Place carries out mapping process. Therefore,, although foregoing of the present invention has been described a kind of dynamic process, this dynamic process stillRepresent corresponding state, for example, be stored in database or look-up table in memory.
According to an embodiment of the invention, send ACK/NACK message according to the described first information and the second informationComprise: send each by independent physical uplink control channel PUCCH/ physical uplink link sharing channel PUSCHThe ACK/NACK message of member carrier.
According to an embodiment of the invention, if not being arranged to simultaneously, the subframe in described Scell existsPUSCH and PUCCH are upper to be sent, and on described PUSCH or PUCCH, sends described ACK/NACK message.
According to an embodiment of the invention, if the subframe in described Scell is arranged to simultaneously at PUSCH andThe upper transmission of PUCCH sends described ACK/NACK message on described PUCCH.
Obviously, this is very directly method of one, in this manner, and for becoming in the frequency band defining in Rel-10The grouping of member's carrier wave, the configuration notification that carries out member carrier grouping by the PUCCH/PUSCH of single member carrier is enough, thisBecause there is identical TDD configuration for polymerization member carrier in frequency band. The beneficial effect of above two schemes be withoutBetween frequency band, in member carrier, define new ACK/NACK mapping. But this method will require RAN1/RAN2 specification to occur oneA little PUCCH/ that change each member carrier/member carrier grouping on different frequency bands to be supported in different TDD configurationsOn PUSCH, carry out ACK/NACK feedback.
For the feedback of PUSCH, if support to have the phase in carrier aggregation between the frequency band of member carrier specific T DD configurationWith member carrier scheduling (without across carrier dispatching), there is not PDCCH mapping problems. If the support of this situation is adjusted across carrier waveDegree, should dispatch the ACK/NACK that feed back the PUSCH on all member carriers on member carrier, thus ACK/NACK sequentialProblem still exists, and need to carry out the mapping of newtype. Based on table 2, dispatch for the Serving cell c from subframe nPUSCH transmission, UE will determine subframe n+kPHICHThe corresponding PHICH resource of middle Serving cell c, wherein kPHICHIn table 2 forTDD provides. Therefore, can generate another table 3 being equal to there is identical implication with aforesaid table 1 according to table 2. SubframeN will carry { n-ku| u=0,1 ..., the ACK/NACK of the UL data burst set of U-1}, therefore, can use with forPDSCH transmits two kinds of identical mapping schemes and solves the ACK/NACK problem across PUSCH in CC scheduling situation. Due to this and thisThe aforementioned embodiments of invention has the process being equal to, and therefore will no longer describe in detail here.
Table 2
Table 3
In polymerization between multiple frequency bands member carrier in the situation that, can process ACK/NACK by additional option and reflectPenetrate. The Scell with identical configuration can be separated into CC grouping, and in this grouping, the ACK/NACK of all member carriers is passablePUCCH/PUSCH by predetermined Scell feeds back. For the member carrier with different configurations, can be neatly by instituteThe scheme proposing is applied to different groupings and arranges. The solution of this mixing can obtain signaling spending and ACK/NACKCompromise between efficiency.
