Embodiment

In order to make concrete technical scheme of the present invention, goal of the invention clearer, be described further below in conjunction with concrete execution mode and accompanying drawing.

In 3GPP LTE system, comprise FDD (Frequency Division Duplexing, FDD) and time division duplex (Time Division Duplexing, TDD) dual mode.In LTE TDD system, on a frequency channels, send and receive, separate in time but send and receive, promptly receive and send the different time-gap that uses same frequency carrier.In LTE TDD system, support different ratio of uplink subframe to downlink subframe, thus can be according to different business types, the adjustment ratio of uplink subframe to downlink subframe satisfies the asymmetrical business demand of up-downgoing.Comprise 7 kinds of ratio of uplink subframe to downlink subframe in the LTE TDD system, as shown in table 1, wherein D representes descending sub frame, and U representes sub-frame of uplink, and S representes special subframe.

Table 1

Can find out that from table 1 in the ratio of uplink subframe to downlink subframe 1 to 5, the number of descending sub frame is more than the number of sub-frame of uplink, thereby, can exist the corresponding response message of transfer of data on a plurality of descending sub frames on same sub-frame of uplink, to feed back.Response message can comprise usually and confirm to reply that (Acknowledge ACK), denies replying that (Negative-Acknowledge, NACK), when the feedback response message, response message can carry out chnnel coding through the response message bit to feedback and feed back.In 3GPP LTE system, the response message of the PDSCH that UE need carry at sub-frame of uplink n feeding back downlink subframe n-k or be used for the response message of the PDCCH that indicating downlink SPS discharges.The value of k is shown in descending related subframe set (Downlink association set) K in the table 2, and descending related subframe set K is the descending related subframe set of sub-frame of uplink in each ratio of uplink subframe to downlink subframe.Wherein, K:{k ₀, k ₁... k _M-1.For example, in ratio of uplink subframe to downlink subframe 1, the descending related subframe set K:{7 of corresponding sub-frame of uplink 2,6}, M=2, the value of k can be k ₀=7, perhaps k ₁=6.In other sub-frame of uplink of ratio of uplink subframe to downlink subframe 1, and in other the ratio of uplink subframe to downlink subframe, can be according to the value of confirming k shown in the table 2.

Need to prove that all subframes of descending related subframe set refer to all descending sub frames of comprising among the descending related subframe set K.For instance, in ratio of uplink subframe to downlink subframe 1, all descending sub frames of the descending related subframe set of corresponding sub-frame of uplink 2 are descending sub frame n-7 and descending sub frame n-6.In ratio of uplink subframe to downlink subframe 2, all descending sub frames that the descending related subframe of corresponding sub-frame of uplink 2 combines comprise descending sub frame n-8, descending sub frame n-7, descending sub frame n-4 and descending sub frame n-6.Other situation can be by that analogy.

In all embodiment of the present invention; The descending related subframe set that specific sub-frame of uplink is corresponding specific; The descending related subframe set that sub-frame of uplink is corresponding can refer to the set of all descending sub frames compositions that the response message of descending sub frame transmits in same sub-frame of uplink; Promptly the response message of all descending sub frames transmits in same sub-frame of uplink, and the set that these all descending sub frames are formed is the corresponding descending related subframe set of this sub-frame of uplink.In the embodiment of the invention; The descending related subframe set that each sub-frame of uplink is corresponding under each ratio of uplink subframe to downlink subframe can be as shown in table 2; It also can be alternate manner; The descending related subframe set that for example each sub-frame of uplink is corresponding under each ratio of uplink subframe to downlink subframe does not promptly comprise the descending related subframe set of special subframe for deducting the set behind the special subframe (S) in the descending related subframe set of each shown in the table 2.For example, during ratio of uplink subframe to downlink subframe 2, subframe 1 is a special subframe with subframe 6; Sub-frame of uplink 2 corresponding descending related subframes then as shown in table 2 gather { 8,7,4; Behind the 6} deduction special subframe set for 8,7,4}; { 8,7, sub-frame of uplink 2 corresponding related descending sub frames were gathered when 4} also can be described as ratio of uplink subframe to downlink subframe 2.Special subframe in the embodiment of the invention can refer to comprise descending pilot frequency time slot (Downlink Pilot Timeslot; DwPTS), protection interval (guard period; GP) and uplink pilot time slot (Uplink Pilot Timeslot, UpPTS) special subframe in three territories.

In the embodiment of the invention, the descending related subframe set corresponding with sub-frame of uplink i also can be described as the binding window corresponding with sub-frame of uplink i (bundling window), or the binding window of the response message corresponding with sub-frame of uplink i.

The descending related subframe set K:{k of table 2 ₀, k ₁... k _M-1}

Can find out from table 2, in ratio of uplink subframe to downlink subframe 1 to 5, all exist a sub-frame of uplink need feed back the situation of the response message of a plurality of descending sub frames.For example, in ratio of uplink subframe to downlink subframe 2, UE need feed back the response message of 4 descending sub frames in sub-frame of uplink 2 and sub-frame of uplink 7.

The LTE-A system is the further evolution of 3GPP LTE system and the system of enhancing.Therefore; In the LTE-A system, in the TDD mode, also can communicate according to the ratio of uplink subframe to downlink subframe shown in the table 1; And the PDSCH response message that can carry, or the response message of the PDCCH that is used for indicating downlink SPS release that carries at sub-frame of uplink n feedback subframe n-k as shown in table 2.Under LTE-A TDD system carrier aggregation, each descending sub frame n-k related with sub-frame of uplink n as shown in table 2 has a plurality of descending carriers, therefore, need feed back the response message of a plurality of descending carriers of a plurality of descending sub frames at a sub-frame of uplink.

For in the LTE-A system, report response message on effectively in the physical uplink channel, the embodiment of the invention provides a kind of information transferring method, and is as shown in Figure 1, and this method comprises:

Need to prove that the downlink member carrier in the embodiment of the invention also can be called downlink member sub-district (cell), promptly C can be the number of downlink member sub-district.Member carrier also can be described as the member sub-district; For example main member carrier (PCC; Primary Component Carrier) (Pcell Primarycell), assists member carrier (SCC also to can be described as the main plot; Secondary Component Carrier) also can be described as auxilliary sub-district (Scell, Secondary Cell).Be that PCC or SCC also can be described as Serving cell (Serving Cell).

In embodiments of the present invention, can dispose a plurality of downlink member carriers according to carrier aggregation technology, a plurality of downlink member carriers of configuration can be formed downlink member carrier set, and in embodiments of the present invention, C can be the number of the downlink member carrier of configuration.For downlink member carrier i, corresponding descending related subframe set K can be arranged, for example as shown in table 2, also can be alternate manner, for example be the set behind the descending special subframe of deduction (special subframe) in the descending related subframe set of each shown in the table 2.For a downlink member carrier i, N _iEqual this downlink member carrier i in all descending sub frames that descending related subframe set K is comprised, carry PDSCH descending sub frame number and the descending sub frame that carries the PDCCH that indication SPS discharges number with.

In embodiments of the present invention, set { N _i, i=1,2 ..., C} is all downlink member carriers in all descending sub frames of descending related subframe set, carries number and set number and that form of the descending sub frame that carries the PDCCH that indication SPS discharges of the descending sub frame of PDSCH.At set { N _i, i=1,2 ..., among the C}, according to the value of C, promptly the number of downlink member carrier can be known in this set, to have C value N ₁, N ₂... N _C, the maximum of getting wherein is N.For example, if C=3, then this is gathered and is { N ₁, N ₂, N ₃, if N ₃Be maximum wherein, then maximum N is N ₃

UL grant among all embodiment of the present invention, the transmission that mainly is used for indicating PUSCH promptly is used for dispatching PUSCH, and it sends to UE through physical downlink control channel PDCCH.UL grant can refer to carry the PDCCH of Downlink Control Information (DCI) form 0 or descending control information format 4.Downlink Control Information (DCI) form 0 or descending control information format have mainly comprised and the relevant information of PUSCH transmission for 4 li, and these information are used to indicate the transmission of PUSCH, and the resource allocation information that for example comprises is used to indicate the employed frequency domain resource of this PUSCH.

The sub-frame of uplink that UL grant is corresponding refers to that the PUSCH of this UL grant indication transmits in this sub-frame of uplink, this definition is applicable to all embodiment in the embodiment of the invention.

Step 102: said UE confirms the response message that said sub-frame of uplink carries according to said maximum N, and said response message is sent to said base station at the physical uplink channel.

As shown in Figure 2, the embodiment of the invention provides another kind of information transferring method, comprising:

Step 201: UL grant is sent to UE in the base station, comprises set { N among the said UL grant _i, i=1,2 ..., the maximum N among the C}, said C are the number of the corresponding downlink member carrier of said UE, and C is more than or equal to 2, said N _iFor downlink member carrier i in all descending sub frames of descending related subframe set; Carried said UE the descending sub frame that carries Physical Downlink Shared Channel PDSCH number with carried said UE physical downlink control channel PDCCH descending sub frame number with; Said PDCCH is used to indicate the professional SPS of the descending semi-continuous scheduling that discharges said UE, and it is corresponding that said descending related subframe is gathered the sub-frame of uplink corresponding with said UL grant.

Step 202: the base station receives the response message that UE sends, and said response message is confirmed according to said maximum N by said UE.

As shown in Figure 3, the embodiment of the invention also provides a kind of information transferring method, comprising:

Step 301: the base station comprises set { N in UL grant _i, i=1,2 ..., the maximum N among the C}, said C are the number of the corresponding downlink member carrier of said UE, and C is more than or equal to 2, said N _iFor downlink member carrier i in all descending sub frames of descending related subframe set; Carried said UE the descending sub frame that carries Physical Downlink Shared Channel PDSCH number with carried said UE physical downlink control channel PDCCH descending sub frame number with; Said PDCCH is used to indicate the professional SPS of the descending semi-continuous scheduling that discharges said UE, and it is corresponding that said descending related subframe is gathered the sub-frame of uplink corresponding with said UL grant.

Step 302: the base station sends to user equipment (UE) with said UL grant in descending sub frame.

According to the scheme that the embodiment of the invention provides, the base station can comprise set { N in UL grant _i, i=1,2 ..., the maximum N among the C}, C are the number of downlink member carrier, and C is more than or equal to 2, said N _iFor downlink member carrier i in all descending sub frames of descending related subframe set; Carry PDSCH descending sub frame number and the descending sub frame that carries the PDCCH that indication SPS discharges number with; And to UE transmission UL grant; UE can be according to the set { N that comprises among this UL grant after receiving this UL grant _i, i=1,2 ..., the maximum N among the C} need to confirm the response message of feedback, thereby can realize that response message is in the physical uplink channel.

As shown in Figure 4, the embodiment of the invention provides another kind of information transferring method, comprising:

Step 401:UE receives the UL grant that send the base station, comprises set { N among the said UL grant _i, i=1,2 ..., the maximum N among the C}, said C are the number of downlink member carrier, and C is more than or equal to 2, said N _iFor downlink member carrier i in all descending sub frames of descending related subframe set, carry PDSCH descending sub frame number and the descending sub frame that carries the PDCCH that indication SPS discharges number with.

In embodiments of the present invention, when UE when subframe n feeds back response message on PUSCH, UE can receive one or more up indication UL grant at subframe n-k '.The value of k ' can be as shown in table 3.For example, when ratio of uplink subframe to downlink subframe 1, subframe n=2 or 7 o'clock, k ' got 6, and subframe n=3 or 8 o'clock, k ' got 4.When other ratio of uplink subframe to downlink subframe, can confirm the value of k ' according to table 3.Need to prove; UE feeds back response message at subframe n on PUSCH; Do not necessarily represent UE and can receive UL grant, for example when the PUSCH that sends at subframe n is the re-transmission of up SPS business or upstream data, possibly can not receive any UL grant at subframe n-k ' at subframe n-k '.

The uplink member carrier number of giving UE when configuration is during more than 1, and UE may have PUSCH to send on two up-link carriers at sub-frame of uplink n, and promptly two PUSCH transmit simultaneously, this moment response message only therein a PUSCH go up transmission.For example, if in PUSCH when transmission, arranged on the up main carrier, the PUSCH channel that response message just only can carry at up main carrier, no matter this PUSCH has or not corresponding UL grant at subframe n-k '; If no PUSCH transmission on the up main carrier; Then response message will be in the PUSCH channel of auxilliary carriers carry; Specifically be that the corresponding PUSCH channel of which auxilliary carrier wave can be selected according to the priority of up-link carrier; The auxilliary carrier wave that priority is the highest can perhaps, also can be selected according to the transformat of PUSCH by preferential selection.

When UE when sub-frame of uplink n feeds back response message on PUSCH; If carry the PUSCH of response message corresponding UL grant is arranged; Then this UL grant sends to UE by the base station at descending sub frame n-k '; Just UE receives this UL grant at descending sub frame n-k ', and UE only has a UL grant corresponding with the PUSCH of this carrying response message in the one or more up indication UL grant that descending sub frame n-k ' receives.Can refer to that with the corresponding UL grant of PUSCH that carries response message the base station is used for the PUSCH that carries response message is distributed the UL grant of indication; Also be the PUSCH of UE according to the indication transmission bearer response message of this UL grant; Perhaps UE adjusts the PUSCH that carries response message according to the indication of this UL grant, and perhaps this UL grant is used to indicate the transmission of the PUSCH that carries response message.If carry the PUSCH of response message is that up semi-continuous scheduling business or non-self-adapting retransmit; Then the PUSCH of this carrying response message does not have corresponding UL grant, and then UE does not have and the corresponding ULgrant of PUSCH that carries response message in the one or more up indication UL grant that descending sub frame n-k ' receives.

Table 3

In embodiments of the present invention, can be through the descending distribution indication among the UL grant (DownlinkAssignment Index, DAI) territory, i.e. value through the DAI territory that comprises among the UL grant

Indicate set { N _i, i=1,2 ..., the maximum N among the C}, for example, if C=3, then this is gathered and is { N ₁, N ₂, N ₃, if N ₃Be maximum wherein, maximum N is N ₃, the value in DAI territory then

Be maximum N, promptly

If UE receives a plurality of UL grant, the set { N that then comprises among all UL grant in this step _i, i=1,2 ..., the maximum N among the C} is identical, for example, among a plurality of UL grant that send the base station

All identical.In the embodiment of the invention; Also can only indicate maximum N through the descending distribution indication DAI territory among the corresponding ULgrant of the PUSCH of carrying response message; But in the embodiment of the invention; Maximum N is all indicated in descending distribution indication DAI territory among preferred all UL grant, and promptly the value in the descending distribution indication DAI territory among all UL grant is identical and all equal maximum N.

For example; In LTE-A TDD system, the base station has disposed 2 downlink member carriers to UE, is respectively CC1 and CC2; Under the situation of ratio of uplink subframe to downlink subframe 2, sub-frame of uplink 2 needs the response message of descending sub frame corresponding among the feedback descending related subframe set K as shown in table 2.If CC1 and CC2 scheduling situation in all descending sub frames in descending related subframe set K as shown in table 2 is: CC1 in 4 sub-frame, carry PDSCH subframe number and the subframe of the PDCCH that carries indicating downlink SPS release number and N ₁Be 2, CC2 in 4 sub-frame, carry PDSCH subframe number and the subframe of carrying the PDCCH that indicating downlink SPS discharges number and N ₂Be 1, then gather { N _i, i=1, the maximum of 2} is 2, therefore, the base station sends to the value of UE or UE DAI in the UL grant that subframe n-k ' receives at subframe n-k '

Equal, if a plurality of UL grant are arranged, then among all UL grant

All equal 2.

In embodiments of the present invention, also can be used for indication set { N through newly-increased special territory in UL grant _i, i=1,2 ..., the maximum N among the C} perhaps, also can come explicit or implicit expression indication set { N through other territory among the UL grant _i, i=1,2 ..., the maximum N among the C}.

In embodiments of the present invention, the base station can be confirmed to the scene of the carrier aggregation of UE configuration and the uplink service demand of UE according to the base station to the quantity that UE sends UL grant at subframe n-k '.For example, if having only 1 to the up-link carrier number of UE configuration, then the base station is just sent 1 ULgrant usually on subframe n-k '; If to the up-link carrier number of UE configuration greater than 1; Then the base station can be sent a plurality of UL grant to UE at subframe n-k ' and dispatched a plurality of up-link carriers and send a plurality of PUSCH data simultaneously; The corresponding PUSCH of each UL grant also can only send 1 UL grant and dispatch up-link carrier transmission PUSCH data in a plurality of up-link carriers.

In embodiments of the present invention, UL grant can be any PDCCHDCI form that can be used in indication UL grant, for example can be PDCCH DCI form 0, perhaps also can be for PDCCH DCI format 4 etc.

In embodiments of the present invention, utilize the value in the DAI territory among the UL grant

Indication set { N _i, i=1,2;, during maximum among the C}, can indicate as follows in the embodiment of the invention: can utilize in the example up-downgoing proportioning 1 to 6 as shown in table 1; The value of the DAI of 2 bits among the UL grant is indicated; For example, as shown in table 4, the value of the DAI in detected UL grant 2 corresponding bits are 00 o'clock, if the ratio of uplink subframe to downlink subframe of UE is 2, then

Method as shown in table 4 is merely the value in the DAI territory among a kind of UL of utilization grant that the embodiment of the invention provides

Indication set { N _i, i=1,2 ..., peaked the giving an example among the C}, in embodiments of the present invention, not to how utilizing the DAI territory indication { N among the up indication UL grant _i, i=1,2 ..., the maximum of C} limits.

Wherein, C is the number of the downlink member carrier of configuration, C ₂For transmission mode in the downlink member carrier of configuration is the number of the downlink member carrier of space multiplexing mode, perhaps C ₂The number of the downlink member carrier of corresponding two code words of the Physical Downlink Shared Channel PDSCH that carries in the downlink member carrier for configuration, perhaps C ₂Number for the downlink member carrier of the corresponding 2 bit response messages of transmission mode in the downlink member carrier of configuration.And response message number of bits of feedback

C that the downlink member carrier i of configuration is corresponding is the number of the downlink member carrier of configuration.

Wherein, Transmission mode can be the downlink transfer pattern of downlink member carrier; For example, transmission mode 1 is single antenna transmissions (Single-antenna port, port0) pattern; Transmission mode 2 is transmit diversity (Transmitdiversity) pattern, and transmission mode 4 is Closed-Loop Spatial Multiplexing (Closed-loop spatial multiplexing) pattern.PDSCH can carry two code words under some transmission modes, and for example transmission mode 4, thereby each descending carrier is at the corresponding 2bit response message of a sub-frame.PDSCH carries 1 code word under some transmission modes, transmission mode 1 and 2 for example, thereby each descending carrier is at the corresponding 1bit response message of a sub-frame.

For example, if the transmission mode of downlink member carrier i is pattern 1 and 2, then O _i=1, if the transmission mode of downlink member carrier i is pattern 4, then O _i=2.In embodiments of the present invention, the downlink transfer pattern can be descending carrier corresponding multiple-input and multiple-output (Multiple Input Multiple Output, MIMO) transmission mode.

O _iAlso can be definite through directly being provided with, for example set each descending carrier at the corresponding 1bit response message of a sub-frame, or corresponding 2bit response message etc.

O _iAlso can confirm through the situation of the PDSCH that on descending carrier, receives according to UE.For example if the PDSCH that receives is corresponding 1 code word, then O _i=1; If the PDSCH that receives is corresponding 2 code words, then O _i=2.

In embodiments of the present invention, the response message bit of feedback

N=0 ..., O ^ACK-1 can obtain according to following mode: confirm the response message bit sequence that each descending carrier is corresponding; The corresponding response message bit sequence of each descending carrier sorted obtains a new response message bit sequence, and this new response message bit sequence is the response message bit of feedback.

Wherein, can confirm the corresponding response message bit sequence of descending carrier i of configuration as follows $o_r^{\mathrm{ACK},C{C}_i},r=0,...{,O}^{\mathrm{ACK},{\mathrm{CC}}_i}-1:$

If need carry out the binding of response message space; Then the descending carrier i of configuration transmits descending SPS data for

and as if the descending carrier i that disposes at descending sub frame n-k as shown in table 2 at the corresponding response message of descending sub frame n-k as shown in table 2; Then this SPS data corresponding response message be

is last 1 bit of the response message bit sequence of the descending carrier i correspondence of this configuration; Therefore, this scheme response message that SPS is corresponding comes the corresponding response message bit sequence of the descending carrier i of this configuration backmost.To in the corresponding response message bit sequence of the descending carrier i of configuration not by or those bits of the corresponding response message bit stealing of SPS data, fill with NACK.Even according to set { N _iI=1,2 ... The value of the DAI that maximum N among the C} and downstream grants (DL assignment) comprise; UE estimates the PDCCH that the descending carrier i of this configuration should detect PDSCH or indicate SPS to discharge at descending sub frame n-k as shown in table 2, but UE does not promptly detect the PDCCH that PDSCH does not detect indication SPS release again in the reality, and then the descending carrier i of this configuration is NACK at the corresponding response message bit of this subframe.

If need not carry out response message space binding, then if know that according to the transmission mode of the descending carrier i of this configuration this descending carrier is 1 bit at the corresponding response message bit of each descending sub frame, or O _i=1, confirm that then the descending carrier i of this configuration does not confirm that mode identical with above-mentioned need not carrying out when the space bundlees in the method for the corresponding response message bit sequence of descending sub frame n-k as shown in table 2; If know that according to the transmission mode of the descending carrier i of this configuration this descending carrier is 2 bits at the corresponding response message bit of each descending sub frame, or O _i=2, then the descending carrier i of this configuration at the corresponding response message of descending sub frame n-k as shown in table 2 does

With

And if the descending carrier i of configuration transmits descending SPS data at descending sub frame n-k as shown in table 2, then the corresponding response message of these SPS data does

With Wherein

Can corresponding NACK,

For the corresponding ACK/NACK information bit of actual SPS data, also can

Be the corresponding ACK/NACK information bit of actual SPS data,

Corresponding NACK.To not taken in the corresponding response message bit sequence

of the descending carrier i of configuration by

and

; Or, fill with NACK also not by those bits of the corresponding response message bit stealing of SPS data.Even according to set { N _iI=1,2 ... The value of the DAI that comprises among maximum N among the C} and the DLassignment; UE estimates the PDCCH that the descending carrier i of this configuration should detect PDSCH or indicate SPS to discharge at descending sub frame n-k as shown in table 2, but UE does not promptly detect the PDCCH that PDSCH does not detect indication SPS release again in the reality, and then the descending carrier i of this configuration is 2 bit NACK at the corresponding response message bit of this subframe.

DAI in the above-mentioned steps _i(k) value of the DAI that in the DL assignment that descending sub frame n-k as shown in table 2 receives, comprises for the descending carrier i of this configuration, this DL assignment can be PDCCH form 1/1/1A/1B/1D/2/2A/2B/2C.The descending carrier i that the value of the DAI that comprises among this DL assignment refers to this configuration gives the PDCCH of this UE scheduling in base station till the descending sub frame n-k as shown in table 2 on the descending carrier of this configuration accumulative total number, the DAI value that promptly comprises in this downstream grants is an aggregate-value.

Need to prove, can find out, the bit number of the response message bit sequence that the descending carrier i of configuration is corresponding from top step

Be according to set { N _i, i=1,2 ..., the maximum N among the C} confirms.Simultaneously, the bit in the response message bit sequence that the descending carrier i of this configuration is corresponding also needs according to set { N _i, i=1,2 ..., the maximum N among the C} confirms.Thereby the corresponding response message bit sequence of the descending carrier i that should dispose needs according to set { N _i, i=1,2 ..., the maximum N among the C} confirms.

In this step; After having confirmed the corresponding response message bit sequence of each descending carrier; Can sort to the corresponding response message bit sequence of each descending carrier according to predetermined ordering rule; Obtain a new response message bit sequence, this new response message bit sequence is the response message bit of feedback.Predetermined ordering rule can be that order according to the attribute increasing or decreasing of carrier wave sorts to the corresponding response message of each descending carrier of configuration in the embodiment of the invention; The attribute of carrier wave can be the relative indexing number (Index) of carrier wave or the relative sign (ID) of carrier wave; Perhaps also can be the absolute indices number (carrierIndex) of carrier wave, can also be the frequency size of carrier wave.Need explanation to be, the predetermined ordering rule among the present invention is not restricted to this.

In the embodiment of the invention, this step can be as long as UE receives UL grant at descending sub frame n-k ' as shown in table 3 and promptly carries out, and no matter whether this UL grant is corresponding with the PUSCH that carries response message.If in the descending sub frame n-k ' shown in the table 3; UL grant is not sent to UE in the base station; Or UE does not detect UL grant in n-k ' subframe; Then UE can be according to the bit number of the number M definite response information of the descending sub frame that comprises in the descending sub frame relation integration shown in the table 2 and the response message bit of feedback; Can the value of N in the bit number of above-mentioned definite response information and the definite response feedback information bit process value with M be replaced get final product, specifically confirm that rule is consistent, no longer repetition here.The value that illustrates M is following, and for example, in the ratio of uplink subframe to downlink subframe shown in the table 22, subframe 2 corresponding descending related subframes are gathered K:{k ₀, k ₁... k _M-1Be 8,7,4,6}, therefore, M=4.Equally, under the situation of other subframe or other ratio of uplink subframe to downlink subframe, can carry out the bit number of definite response information equally according to table 2.

In the embodiment of the invention; In this step; It is corresponding with UL grant at descending sub frame n-k ' also can to work as the PUSCH that carries response message; When the transmission of promptly carrying the PUSCH of response message was indicated by the UL grant that receives among the descending sub frame n-k ', UE was according to the bit number of the maximum N definite response information that comprises among this UL grant and the response message bit of feedback.Do not have corresponding UL grant if carry the PUSCH of response message at descending sub frame n-k ', UE can be according to according to the bit number of the number M definite response information of the descending sub frame that comprises in the descending sub frame relation integration shown in the table 2 and the response message bit of feedback.Therefore; When UE receives the corresponding UL grant of PUSCH that carries response message at the descending sub frame n-k ' shown in the table 3; When the transmission of promptly carrying the PUSCH of response message was indicated by the UL grant of the correspondence that receives at the descending sub frame n-k ' shown in the table 3, UE was according to the set { N that comprises among this corresponding UL grant _i, i=1,2 ..., the bit number of the maximum N definite response information among the C} and the response message bit of feedback; When the PUSCH that carries response message does not have corresponding ULgrant at the descending sub frame n-k ' shown in the table 3; Promptly work as UE and do not receive the UL grant corresponding with the PUSCH that carries response message at the descending sub frame n-k ' shown in the table 3; Or the PUSCH that carries response message can't help when the UL grant indication that the descending sub frame n-k ' shown in the table 3 receives, and UE can be according to the bit number of the number M definite response information of the descending sub frame that comprises in the descending sub frame relation integration shown in the table 2 and the response message bit of feedback.Specifically the rule according to the response message bit of the bit number of the number M definite response information of the descending sub frame that comprises in maximum N or the descending sub frame relation integration and feedback is consistent with the description of front, no longer repeats here.

The bit number of the maximum N definite response information that when descending sub frame n-k ' has corresponding UL grant, comprises in just according to this UL grant as the PUSCH that carries response message and the response message bit of feedback can be avoided producing because the corresponding UL grant of the PUSCH of non-bearing response message loses the problem that causes base station and UE that the bit number of the response message of actual transmissions is understood differently and causes.For example; UE feeds back response message at subframe n on PUSCH, in two up-link carriers of UE, the PUSCH on the up main carrier is that up SPS is professional at this moment; PUSCH on this up main carrier does not have corresponding ULgrant at descending sub frame n-k '; Because of on the up main carrier PUSCH being arranged, response message sends on main carrier, promptly carries on the professional PUSCH of SPS at main carrier and sends response message.If the base station has been sent the PUSCH on the auxilliary carrier wave of UL grant scheduling at descending sub frame n-k ' to UE; If do not limit UE only according to the bit number of the value definite response feedback information of carrying the DAI territory among the corresponding UL grant of response message and the feedback bits of response message; Then in a single day the UL grant of the auxilliary carrier wave of scheduling loses; Then UE sends response message according to the bit number of the definite response message feedback of the number M of descending sub frame in the descending related subframe set and the feedback bits of response message on the PUSCH of main carrier channel.And the base station thinks that UE is according to the bit number of the definite response message feedback of the value in DAI territory among the UL grant of the auxilliary carrier wave of scheduling and the feedback bits of response message; Cause thereby cause base station and UE that the bit number of the response message of actual transmissions is understood differently, thereby influence the correct reception of data and response message.And if limit UE according to the bit number of the value definite response feedback information in the DAI territory among the corresponding UL grant of the PUSCH that carries response message and the feedback bits of response message; The problems referred to above can not take place then; Because if carry the PUSCH of response message is that SPS or non-self-adapting retransmit; Then base station and UE are all clear knows not have UL grant this moment; The response message that on PUSCH, sends is the bit number and the feedback bits of response message of the response message feedback confirmed according to the number M of descending sub frame in the descending related subframe set, and the PUSCH that can not carry response message is dynamic dispatching but situation that its corresponding ULgrant also loses, because lose as if UL grant; UE just can not know has such PUSCH to exist, thereby also can not be chosen in upward response information transmission of such PUSCH.

Need to prove that the sub-frame of uplink that the UL grant that UE receives at descending sub frame n-k ' as shown in table 3 is corresponding is n, promptly refer to the transmission that UL grant that UE receives at descending sub frame n-k ' as shown in table 3 is used for indicating subframe n PUSCH.The transmission of a PUSCH channel of a UL grant indication.A PUSCH channel can a corresponding data transmission block or corresponding two transmission blocks (or claiming code word).

Need to prove that the described method of step 402 not only is applicable to the situation at PUSCH channel response message, also is applicable to the situation at physical uplink channel response messages such as PUCCH channels.

Step 403:UE is according to the bit number of said response message and the response message bit definite response information of feedback.

In embodiments of the present invention, can on PUSCH, take the number of modulation symbol based on the bit number definite response information of the response message that obtains in the step 402.If the corresponding multilayer (Layer) of this PUSCH, the number of the modulation symbol that then can on each layer of PUSCH, take according to the bit number definite response information of response message.The symbol numbers Q ' that for example, can on PUSCH, take according to formula (1) definite response information.

Wherein, O ^ACKBe total response message number of bits of feedback;

The transmission bandwidth of PUSCH when just passing for same transmission block;

Transmission bandwidth for current subframe PUSCH;

Shared single-carrier frequency division multiple access (Single-carrier Frequency DivisionMultiple Access, number SC-FDMA) when just passing for same transmission block;

Be the skew of response message with respect to data MCS; C ⁽⁰⁾And C ⁽¹⁾Be respectively the number of the code block that the corresponding data of first code word and second code word are divided into when chnnel coding;

With Be respectively the information bit and the CRC check bit number sum of first code word and r code block of second code word; When UCI is HARQ-ACK,

When UCI is RI,

The value with Value by high-rise (RRC, Radio ResourceControl) signaling, and select based on the MIMO transmission mode of PUSCH.

Need to prove that if the only corresponding data transmission block (promptly having only a code word) of PUSCH, then the concrete calculating of Q ' also can be undertaken by following formula (1 '), it is of equal value with formula 1 in the case.Wherein the implication of each symbol is the same with formula, repeats no more here:

Perhaps, Q ' also can obtain by following formula (1 "), formula (1 ") be:

$Q^{\′}=\max [\min (Q_{\mathrm{temp}}^{\′},4\·M_{\mathrm{sc}}^{\mathrm{PUSCH}}),Q_{\min }^{\′}],---\left(1^{,,}\right)$

If O≤2, then Q ' _Min=O, otherwise Q ' _Min=| 2O/Q ' _m|

$Q_m^{\′}=\min (Q_m^1,Q_m^2)$

Wherein

representes the order of modulation that the 1st transmission block is corresponding; The corresponding order of modulation of the 2nd transmission block of

expression, the transmission bandwidth of PUSCH when

just passes for first transmission block;

is first transmission block shared single-carrier frequency division multiple access (Single-carrier FrequencyDivision Multiple Access when just passing; SC-FDMA) number of symbol,

is the transmission bandwidth of second transmission block PUSCH when just passing;

is second transmission block shared single-carrier frequency division multiple access (Single-carrier Frequency Division Multiple Access when just passing; SC-FDMA) number of symbol; The implication of all the other symbols is the same with formula, repeats no more here.

Bit number Q behind the modulation symbol number Q ' definite response information channel coding that can take according to response message for example, can obtain the bit number Q after the response message chnnel coding according to formula (2).

Q＝Q _m·Q′ (2)

Wherein, Q is the bit number after the UCI chnnel coding, Q _mBe order of modulation.

In embodiments of the present invention, when the corresponding multilayer (layer) of this PUSCH, then can be according to formula (1) and the bit number of (2) definite response information behind each layer upper signal channel coding of PUSCH.

Can confirm the method for chnnel coding according to the bit number of response message.For example, if the bit number of response message less than 11, then can utilize Randt's Miller (RM, Reed Muller) (32,11) sign indicating number to encode; If the bit number of response message greater than 11, then can utilize two RM sign indicating numbers to encode.

Then, can carry out chnnel coding to the response message bit that feeds back, the response message bits of encoded of feeding back is become the Q bit according to the bit number Q after the response message chnnel coding that obtains and the channel coding method of selection.

Step 404:UE is transferred to the base station with the response message that obtains.

UE can be mapped to the response message bit that behind coding, obtains and send to the base station on the PUSCH.

PUSCH in this step is for carrying the PUSCH of response message.When step 402 receives UL grant when promptly carrying out at descending sub frame n-k ' as shown in table 3; The PUSCH of this carrying response message not necessarily with step 401 in the UL grant that sends of the base station that receives of UE corresponding; Promptly the UL grant that sends of the base station that not necessarily received by UE in the step 401 of this PUSCH indicates; The UL grant that send the base station that is perhaps not necessarily received by UE in the step 401 for the transmission of this PUSCH indicates, and for example this PUSCH possibly be professional SPS of up semi-continuous scheduling or non-self-adapting re-transmission.When step 402 only when UE when the descending sub frame n-k ' shown in the table 3 receives the corresponding UL grant of the PUSCH that carries response message; UE is during just according to the response message bit of the bit number of maximum N definite response information and feedback; The PUSCH that carries response message in this step is indicated by the UL grant in the step 401, also is that the UL grant that UE receives in the step 401 is used for indicating this step to carry the transmission of the PUSCH of response message.When the said PUSCH channel of qualification is the PUSCH channel of said UL grant correspondence; Can avoid producing because the corresponding UL grant of the PUSCH of non-bearing response message loses the problem that causes base station and UE that the bit number of the response message of actual transmissions is understood differently and causes, labor can refer step 402.

In embodiments of the present invention, UE can further include step 405 after response message is transferred to the base station.

Step 405: the base station receives the channel information that UE sends, and the response message that UE is sent detects.

In this step, the base station is according to the set { N that comprises among the up indication UL grant that sends to subscriber equipment _i, i=1,2 ..., the maximum N among the C} receives the response message that UE sends, and can comprise:

The modulation symbol number Q ' that the response message that calculating UE sends takies.

In this step, if the corresponding multilayer (layer) of PUSCH, what then this step was calculated is the modulation symbol number that UCI takies on each layer of PUSCH.

In this step, the base station can be according to the set { N that in the ULgrant that UE sends, comprises at descending sub frame n-k ' as shown in table 3 _i, i=1,2 ..., the maximum N among the C} confirms the corresponding number of bits of feedback of response message that UE sends, the method for number of specifically confirming to confirm in method and the step 402 to feed back the response message bit is consistent, repeats no more here.

The modulation symbol number Q ' that the response message that the number of bits of feedback calculating UE that the response message that send based on the UE that confirms the base station is corresponding sends takies.Computational methods are identical with step 403, repeat no more here.

Then, the response message with the UE transmission of transfer of data can be isolated according to Q ' in the base station.

The modulation symbol number that the response message that send according to the UE that obtains the base station takies also can combine to separate steps such as channel interleaving, isolates the response message with the UE transmission of transfer of data.Specifically can refer to isolate the corresponding modulation symbol of response message with the UE transmission of transfer of data.

The base station can be according to the response message that UE sends the number of corresponding feedback bits; Confirm multiple candidate's control information bit sequence; And every kind of candidate's control information bit sequence encoded; For example, all identical bit sequences of number of feedback bits that can be corresponding with the response message that UE sends are as candidate's control information bit sequence.For instance, when the bit number of the response message that sends with the UE of transfer of data was 12, candidate's control information bit sequence had 212 kinds.

The number of the feedback bits that the response message that send according to the UE that confirms the base station is corresponding is selected the coding method of candidate's control information, and identical method is encoded to candidate's control information in employing and the step 403, and detail repeats no more here.

Whether the base station can be according to candidate's control information bit corresponding codes bit sequence, and the response message that UE is sent detects, be the response message that UE sends to judge this candidate's control information bit sequence.

Detection criteria in this step has multiple; With a kind of implementation in the Maximum Likelihood Detection is example; Each candidate's control information bit sequence is encoded in the base station; The conjugate multiplication of the modulation symbol that the modulation of the candidate's control information bit sequence behind coding back is corresponding with isolated response message, the real part of again the product addition being got and being worth, the value that obtains is called likelihood value; Perhaps; With the conjugate multiplication of local frequency pilot sign with the frequency pilot sign that receives; The product addition that a plurality of frequency pilot signs are corresponding obtains first and value; The product addition that candidate's control information is corresponding obtains second and value, with first with value and second and be worth that addition is again got at last and the real part that is worth as likelihood value; The corresponding information bit sequence of response message that base station candidate's control information bit sequence that likelihood value of maximum is corresponding sends as UE.

Information transferring method according to the embodiment of the invention provides comprises set { N among the UL grant through the base station transmission _i, i=1,2 ..., the maximum definite response information of C} has realized that response message is in physical uplink channel such as PUSCH or PDSCH under the LTE-A TDD system.And UE can reduce the influence to transfer of data that data are punched in a large number and caused according to the number of sub frames feedback response message of actual schedule under normal conditions, can further guarantee the response message transmission performance.In addition,, can not bring base station and UE the inconsistent problem of response message bit number, guarantee the correct reception of response message and data because UL grant loses to feedback according to the method that the embodiment of the invention provides.

indication in DAI territory among the UL grant; Also can be through newly-increased special territory in UL grant; Be used to indicate maximum N '; Perhaps, also can come explicit or implicit expression indication N ' through other territory among the UL grant.

Step 802: said UE sends to said base station with said response message at the physical uplink channel according to said maximum N ' definite response information.

As shown in Figure 9; The embodiment of the invention provides another kind of information transferring method; The said maximum N ' of value

indication with through DAI territory among the UL grant is that example describes, and this method comprises:

Step 901:UE receives the UL grant that send the base station, the descending distribution indication DAI territory indication set among the said UL grant N ' _i, i=1,2 ..., the maximum N ' among the M}, M are the number of descending sub frame in the corresponding descending related subframe set of said UE, N ' _iFor the number of the number of the downstream arrangements carrier wave of the Physical Downlink Shared Channel PDSCH that carried said UE among the descending sub frame i in descending related subframe set and the downstream arrangements carrier wave of the physical downlink control channel PDCCH of having carried said UE with; Said PDCCH is used to indicate the professional SPS of the descending semi-continuous scheduling that discharges said UE, and it is corresponding that said descending related subframe is gathered the sub-frame of uplink corresponding with said UL grant.

When UE when sub-frame of uplink n feeds back response message on PUSCH, UE can receive one or more up indication UL grant at descending sub frame n-k '.The value of k ' can be as shown in table 3.This step can through the DAI territory indication set of UE in the UL grant that subframe n-k ' receives N ' _i, i=1,2 ..., the maximum N ' among the M}.Descending sub frame i during wherein the descending related subframe in this step is gathered, i=1,2 ..., the descending sub frame n-k in the descending related subframe set that M can be corresponding as shown in table 2 _I-1, k ∈ K.Thereby N ' _iAlso be the descending sub frame n-k in descending related subframe set as shown in table 2 _I-1In carry PDSCH the downstream arrangements carrier wave number and the downstream arrangements carrier wave that carries the PDCCH that the descending SPS of this UE of indication discharges number with.Promptly at descending sub frame n-k _I-1The number of the number of having carried the downstream arrangements carrier wave of giving the PDSCH data that this UE sends in the base station and the downstream arrangements carrier wave that has carried the PDCCH that the descending SPS of indication this UE that sends for this UE in the base station discharges with.

For example; In LTE-A TDD system, the base station has disposed 2 downlink member carriers to UE, is respectively CC1 and CC2; Under the situation of ratio of uplink subframe to downlink subframe 2, sub-frame of uplink 2 needs the response message of descending sub frame corresponding in the feedback descending related subframe set as shown in table 2.If CC1 with the scheduling situation of CC2 in all descending sub frames of descending related subframe set as shown in table 2 is: have only CC1 to carry PDSCH at first descending sub frame, i.e. N ' ₁Be 1; PDSCH, i.e. N ' have all been carried at second descending sub frame CC1 and CC2 ₂Be 2; Have only CC2 to carry PDSCH at the 3rd descending sub frame, i.e. N ' ₃Be 1; Have only CC1 to carry PDSCH at the 4th descending sub frame, i.e. N ' ₄Be 1; Then set N ' _i, i=1,2 ..., M}={N ' _i, i=1,2 ..., 4}={N ' ₁, N ' ₂, N ' ₃, N ' ₄Maximum be 2, therefore, the base station sends to the value in UE or UE descending distribution indication DAI territory in the UL grant that subframe n-k ' receives at subframe n-k '

Equal 2, if a plurality of UL grant are arranged, then among all UL grant

All be 2.

If the value of maximum N ' is greater than 1, O then ^ACK=4;

If the value of maximum N ' equals 1, then O wherein _iBe the descending sub frame n-k in descending related subframe set as shown in table 2 _I-1Carry PDSCH or carry the bit number of that downstream arrangements carrier wave of the PDCCH that indicates SPS release at the corresponding response message of this subframe; This value confirms that for example transmission mode is for the MIMO transmission mode of this descending carrier configuration at 0 o'clock by this base station, and this value is 1; Transmission mode is 4 o'clock, and this value is 2; Perhaps O ^ACK=M carries out the binding of response message space to each subframe.Even the value of maximum N ' equals 1, and then the bit number of the response message of feedback is by the number decision of descending sub frame in the descending related subframe set.

The response message bit of feedback can be confirmed according to following mode:

If the value of maximum N ' is greater than 1; Then: confirm the response message bit sequence that each descending carrier is corresponding earlier; According to predetermined ordering rule the corresponding response message bit sequence of each descending carrier is sorted and obtain a new response message bit sequence, this new response message bit sequence is the response message bit of feedback.Predetermined ordering rule can be that the order according to the attribute increasing or decreasing of carrier wave sorts to the corresponding response message of each descending carrier of configuration; The attribute of carrier wave can be the relative indexing number (Index) of carrier wave or the relative sign (ID) of carrier wave; Perhaps also can be the absolute indices number (carrier Index) of carrier wave, can also be the frequency size of carrier wave.

If the value of maximum N ' equals 1; Then: confirm the response message bit sequence that each descending sub frame is corresponding earlier; According to predetermined ordering rule the corresponding response message bit sequence of each descending sub frame is sorted and obtain a new response message bit sequence, this new response message bit sequence is the response message bit of feedback.Predetermined ordering rule be descending sub frame in gathering according to following related subframe as shown in table 2 from left to right a rank order on the time.Do not carry the corresponding response message of that subframe of the PDCCH that indication SPS discharges with 1 bit or 2 bit NACK replacement for not carrying PDSCH yet.

Step 903: according to the bit number of response message and the response message bit definite response information of feedback.

The modulation symbol number Q ' that the response message that calculating UE sends takies.

In this step, if the corresponding multilayer (layer) of PUSCH, what then this step was calculated is the modulation symbol number that UCI takies on each layer of PUSCH.

In this step, the set that base station elder generation basis comprises in the ULgrant that UE sends at descending sub frame n-k ' as shown in table 3 N ' _i, i=1,2 ..., the maximum N ' among the M} confirms the corresponding number of bits of feedback of response message that UE sends, the method for number of specifically confirming to confirm in method and the step 902 to feed back the response message bit is consistent, repeats no more here.

The modulation symbol number Q ' that the response message that the number of bits of feedback calculating UE that the response message that send based on the UE that confirms the base station is corresponding sends takies.Computational methods are identical with step 903, repeat no more here.

Further, the response message with the UE transmission of transfer of data can be isolated according to Q ' in the base station.

The modulation symbol number that the base station can take according to the response message that the UE that obtains sends also can combine to separate steps such as channel interleaving, isolates the response message with the UE transmission of transfer of data.For example can isolate the corresponding modulation symbol of response message with the UE transmission of transfer of data.

Then, the base station can be according to the response message that the UE that confirms sends the number of corresponding feedback bits, confirm multiple candidate's control information bit sequence, and every kind of candidate's control information bit sequence encoded; But refer step 405 repeats no more here.

Whether the base station can be according to candidate's control information bit corresponding codes bit sequence, and the response message that UE is sent detects, be the response message that UE sends to judge this candidate's control information bit sequence.But this step refer step 405 repeats no more here.
