A kind of feedback method to multicarrier response message that one embodiment of the invention provides, referring to Fig. 1, described method comprises:

Step 11: the response message generating according to each member carrier, determine the feedback states to described response message, described feedback states at least comprises the first state and the second state.

In LTE-A carrier aggregation system, as subscriber equipment (User Equipment, while UE) accessing a plurality of downlink member carrier simultaneously, if received to transfer of data and the reception of UE correct on the PDSCH of a member carrier, or received indicating downlink semi-continuous scheduling (Semi-persistentScheduling, SPS) stop the DCI of (Release), this member carrier is generated and confirms (ACK) response message; If the transfer of data having received on the PDSCH of a member carrier to UE still receives mistake, this member carrier is generated and denies (NACK) response message; If do not receive any transfer of data on the PDSCH of a member carrier, do not receive indicating downlink semi-continuous scheduling (Semi-persistentScheduling yet, SPS) stop the DCI of (Release), this member carrier is not generated to response message, be designated as and generate response message DTX.For sake of convenience, do not producing obscure in the situation that, below the transfer of data summary that UE received on the PDSCH of a member carrier to it for UE, on a member carrier, received PDSCH transmission.

Described at least one predetermined member carrier can be, descending main member carrier, or described at least one predetermined member carrier is the first member carrier, the Downlink Control Information DCI that this first member carrier is corresponding is configured on descending main member carrier and transmits, at this moment, the corresponding DCI of PDSCH on this first member carrier is transmitted by descending main member carrier, this first member carrier can be for one or more, or described at least one predetermined member carrier comprises descending main member carrier and the first member carrier simultaneously.Wherein, in LTE-A carrier aggregation system, during for a plurality of member carrier of user device configuration, can define a descending main member carrier, for wireless link failure monitor and the system message update of subscriber equipment.Using the member carrier except predetermined member carrier in the above-mentioned a plurality of member carriers that send simultaneously as non-predetermined member carrier,

In embodiments of the present invention, the LTE-A carrier aggregation system response message of mainly take feedback scene describes as example, but the principle of the invention is all suitable for for all carrier aggregation systems.In addition, if do not do particular determination, Downlink Control Information (Downlink Control Information, DCI) comprises the DCI that is used to indicate PDSCH transmission or descending SPS termination.

Above-mentioned the first state indication receives only the data (comprising PDSCH and the DCI stopping for SPS) transmitted on whole described predetermined member carriers and to described predetermined member carrier feedback acknowledgment response message all, described the second state indication receives the data of transmitting at least one non-predetermined member carrier, and do not find any loss of data, and to the member carrier of all transmission data that receive feedback acknowledgment response message all.

In above-mentioned steps, according to the response message of member carrier, can comprise according to the confirmation response message that member carrier is generated, according to member carrier is generated deny response message and according to member carrier is not generated to response message.

Further, in order to make feedback to response message exactly, the embodiment of the present invention can be confirmed whether to receive all member carriers of current subframe by the indication field of carrying in member carrier, for example in the DCI of non-predetermined member carrier, carry indication field, when knowing according to this indication field, receive the member carrier of all transmission data and during to the whole feedback acknowledgment response message of this member carrier, determine to be the second state to the feedback states of described response message.

Step 12: generate response message to be transmitted and this response message to be transmitted is sent to up direction according to described feedback states.

In particular, the scene that the embodiment of the present invention receives a plurality of downlink member carriers to subscriber equipment in FDD system in same subframe provides a kind of feedback and transmission plan of new multicarrier response message.

A kind of feedback method to multicarrier response message below another embodiment of the present invention being provided is elaborated.

Step S1: receive the data of transmitting on each downlink member carrier of current subframe.

UE receives the data of transmitting on the downlink member carrier from base station, for guaranteeing that response message is made to correct feedback, base station need to be by carrying descending distribution indication (DownlinkAssignment Index in the DCI of member carrier, DAI) field is helped subscriber equipment and is detected whether there is DCI loss, to avoid subscriber equipment to feed back mistakenly response message when having DCI to lose.

At LTE time division duplex (Time Division Duplex, TDD) in system, DCI comprises independently DAI command field, and DAI command field is used to indicate in associated descending sub frame set, and the descending sub frame receiving till current is distributed to the accumulative total number of the DCI of UE.Yet, in LTE-A FDD system, in DCI, there is no independently DAI command field, cannot to the response message of a plurality of member carriers, make correct feedback according to the DAI command field in existing DCI.So the embodiment of the present invention has proposed a kind of feedback scheme of new multicarrier response message, this scheme can either be applied in FDD system and also can be applied in TDD system.

When stating indication field in realization, the embodiment of the present invention has been analysed in depth the feature of carrier aggregation system, discovery is configured in the corresponding DCI of each downlink member carrier that feeds back response message in same uplink member carrier to a UE, in same subframe, there is identical through-put power and control (Transmission Power Control, TPC) command field, for system, sending identical TPC command field is redundancy.So, can utilize the TPC command field of redundancy to realize indication DAI field, this implementation, without increase extra bit for DCI, takes full advantage of existing system resource, has improved the utilance of resource.

For LTE-AFDD system, in order to guarantee that the original function of TPC command field can not lack, in a plurality of member carriers that subtend UE sends simultaneously, first the embodiment of the present invention arranges one or more predetermined member carriers, for example descending main member carrier or the first member carrier, the Downlink Control Information DCI that this first member carrier is corresponding is configured on descending main member carrier and transmits, the TPC command field of this predetermined member carrier DCI is changed, still be interpreted as TPC command word, realized the original function of TPC command field; Using in the above-mentioned a plurality of member carriers that send, the member carrier except predetermined member carrier is as non-predetermined member carrier simultaneously, the TPC command field in this non-predetermined member carrier DCI is reinterpreted is used as DAI field.Different from LTE TDD system, described each member carrier of DAI command word indication being construed to by TPC command field in the embodiment of the present invention is the sum to the DCI of terminal in current sub-frame allocation.UE just can know that according to arbitrary DAI field of receiving current subframe base station sends to the sum of member carrier of all transmission data of UE.

Can find out, above-mentioned processing mode is that the TPC command field of LTE-AFDD system DCI is made to a public field, this public field is construed to TPC command word in the corresponding DCI of at least one preassigned member carrier (as descending main member carrier or be configured in the member carrier of descending main member carrier transmission DCI), in DCI corresponding to all the other member carriers, is construed to DAI command word.

Be appreciated that when the technical scheme of the embodiment of the present invention is applied in TDD system, need to system in DAI command word in the DCI of non-predetermined member carrier be set to current sub-frame allocation to the sum of the DCI of terminal.

Step S2: according to the response message of described each member carrier, determine the feedback states to described response message.

When UE on the PDSCH of a member carrier, received to the transfer of data of UE and receive correct, or, received the DCI that indicating downlink SPS stops, this member carrier is generated and confirms response message; The transfer of data having received on the PDSCH of a member carrier to UE as UE still receives mistake, and this member carrier is generated and denies response message; If do not receive any transfer of data on the PDSCH of a member carrier, do not receive indicating downlink semi-continuous scheduling (Semi-persistentScheduling yet, SPS) stop the DCI of (Release), this member carrier is not generated to response message, be designated as and generate response message DTX.For sake of convenience, do not producing obscure in the situation that, below the transfer of data summary that UE received on the PDSCH of a member carrier to it for UE, on a member carrier, received PDSCH transmission.

In above-mentioned steps S2, according to the response message of each member carrier, comprise according to the confirmation response message that member carrier is generated, according to member carrier is generated deny response message and according to member carrier is not generated to response message.

Owing to having distributed in LTE-A system by 1 or 2 bits, the feedback to response message is passed to base station, in order to make full use of existing Internet resources, the embodiment of the present invention is by the setting to feedback states, can guarantee to pass to base station by the feedback of a plurality of member carrier response messages being carried on to 1 or 2 bits, this processing mode has improved the utilance of conventional network resources.

Above-mentioned feedback states at least comprises the first state and the second state in embodiments of the present invention, described the first state indication only receives the data transmitted on whole described predetermined member carriers and to the whole feedback acknowledgment response messages of described predetermined member carrier, is expressed as ACK0 state; When described the second state indication receives at least one non-predetermined member carrier, and do not have loss of data, and to the whole feedback acknowledgment response messages of described all member carriers, be expressed as ACK1 state, these all member carriers are the member carrier of transmission data.

But be not limited to this, can be according to actual needs or the feedback capability of network the quantity of the indicated content of above-mentioned feedback states and above-mentioned feedback states is set.As, when the feedback capability of the more accurate feedback information of actual needs or network is stronger, the indicated content of above-mentioned feedback states more refinement some, the quantity of feedback states can be more, at this moment need to increase corresponding bit so that this feedback states is passed to base station; When the feedback capability of or network less demanding to the accuracy of feedback information has in limited time, a kind of content of feedback states indication can be summarized, and the quantity of feedback states can be lacked.

Wherein, for above-mentioned the second state, for guarantee UE can know whether receive that current subframe base station sends for transmitting whole member carriers of data, and whether UE has made response message to the member carrier of whole transmission data, the embodiment of the present invention is carried indication field in member carrier, and this indication field indicates current subframe base station to send to the sum of the DCI of UE.

To in the technical scheme of the embodiment of the present invention, except above-mentioned the first state (ACK0 state) and the second state (ACK1 state), the setting of the feedback states of UE is carried out to exemplary explanation below, at least comprises following four kinds of situations:

The first situation,

In this case, except above-mentioned the first state (ACK0 state) and the second state (ACK1 state), also comprise the third state (NACK state) and the 4th state (DTX ₀state).

Wherein, when the arbitrary member carrier generation in described each member carrier receiving is denied to response message, determine to be the third state to the feedback states of described response message, be expressed as NACK state; To receiving the transfer of data at least one non-predetermined member carrier, and while confirming current subframe generation loss of data according to described indication field (as the TPC command field in DCI), determine to be the 4th state to the feedback states of described response message, be expressed as DTX ₀state.

The second situation,

In this case, except above-mentioned the first state (ACK0 state) and the second state (ACK1 state), also comprise the 5th state (NACK ₁state).

When arbitrary described each member carrier generation receiving is denied to response message, or, to receiving the transfer of data at least one non-predetermined member carrier, and while confirming current subframe generation loss of data according to described indication field (as the TPC command field in DCI), determine to be the 5th state to the feedback states of described response message, be expressed as NACK ₁state, can find out, the content of this state indication is relatively summarized, and has comprised NACK state and DTX in the first situation ₀state.

The third situation,

In this case, except above-mentioned the first state (ACK0 state) and the second state (ACK1 state), also comprise the 6th state (NACK 2 states) and the 7th state (ACK2 state).

Wherein, when the whole generations in described each member carrier receiving are denied to response message, or, to receiving the transfer of data at least one non-predetermined member carrier, and while confirming current subframe generation loss of data according to described indication field (as the TPC command field in DCI), determine to be the 6th state to the feedback states of described response message, be expressed as NACK2 state

To receiving the transfer of data at least one non-predetermined member carrier, and confirm to receive all member carriers of current subframe according to described indication field, if arbitrary described predetermined member carrier is generated and denies response message or do not feed back response message, and when all non-predetermined member carriers are all generated to confirmation response message, determine to be the 7th state to the feedback states of described response message, be expressed as ACK2 state.

The 4th kind of situation,

In this case, except above-mentioned the first state (ACK0 state) and the second state (ACK1 state), also comprise the 8th state (NACK0 state) and the 9th state (NACK1 state).

When not receiving indication field (as the TPC command field in DCI) and predetermined member carrier generation being denied to response message in described non-predetermined member carrier, or, in described non-predetermined member carrier, receive indication field and detect while there is loss of data, determine to be the 8th state to the feedback states of described response message, be expressed as NACK0 state;

When not receiving indication field and predetermined member carrier do not generated to response message in described non-predetermined member carrier, or, when receiving indication field but predetermined member carrier generation being denied to response message in described non-predetermined member carrier, determine to be the 9th state to the feedback states of described response message, be expressed as NACK1 state.

Because the non-predetermined member carrier for to UE transmission data all comprises DCI, and the embodiment of the present invention is for this DCI is provided with indication field, when definite the 8th state and the 9th state, also can be described below:

When not receiving DCI and predetermined member carrier generation being denied to response message in described non-predetermined member carrier, or, in described non-predetermined member carrier, receive DCI and detect while there is loss of data, determining to be the 8th state to the feedback states of described response message;

When not receiving DCI and predetermined member carrier do not generated to response message in described non-predetermined member carrier, or, when receiving DCI but predetermined member carrier generation being denied to response message in described non-predetermined member carrier, determine to be the 9th state to the feedback states of described response message.

Can utilize in the following way the DAI command field in DCI, judge whether to occur DCI and lose, whether loss of data occurred.UE receives a plurality of member carriers in current subframe, each member carrier disposes DCI separately, obtain the DAI command word (the DAI command word being interpreted as by public field) in DCI, the quantity of the DCI receiving (quantity of each member carrier receiving) and the indicated count value of DAI command word are compared, if identical, illustrate that DCI does not lose, UE has received the member carrier of these UE data of all carryings of current subframe.If the DCI quantity receiving is less than the indicated count value of DAI command word, DCI detected and lose, UE does not receive all member carriers of current subframe.

When UE does not receive DAI command word, at this moment, possible base station only sends downlink data packet by predetermined member carrier to UE, also may be in the transmitting procedure of downlink data packet, lost all non-predetermined member carriers, UE cannot judge whether DCI loses according to DAI command word.But because UE can be known predetermined member carrier and quantity thereof, UE can make response message and obtain the feedback states to predetermined member carrier predetermined member carrier, as when all predetermined member carriers are all recognized to response message, feedback states is ACK0 state.Therefore, distinguish indication ACK0 and this two states of ACK1, when to base station feedback state, contribute to base station to detect UE and whether lost the whole DCI that include DAI command word that send.

For the ease of the clear technical scheme of describing the embodiment of the present invention, in an embodiment of the present invention, adopted the printed words such as " first ", " second " to distinguish the essentially identical identical entry of function and efficacy or similar item, it will be appreciated by those skilled in the art that the printed words such as " first ", " second " do not limit quantity and execution order.

According to the feedback capability of network, choose above-mentioned feedback states, for example, when network is carried at feedback states by 2bit while being sent to base station in response message to be transmitted, choose 2 kinds, 3 kinds or 4 kinds of feedback states, can pre-define a form, need to indicate each state mapping to become 2 bit b (0) b (1).For example determine that feedback states is above-mentioned the first situation, the first situation comprises the first state, the second state, the third state and the 4th state, i.e. ACK0 state, ACK1 state, NACK state and DTX ₀during state, according to these four kinds of feedback states, generate respectively different response message to be transmitted, and this response message to be transmitted is mapped as to a kind of in following combination: 00,11,10,01.Can form mapping form by the mapping result obtaining, for example, a kind of mapping form of definition can be as shown in table 1.

Wherein, CSI channel refers to that subscriber equipment is to the PUCCH channel of base station feedback channel condition information.

Above-mentioned indication PUCCH form can be PUCCH form 2/2a/2b in LTE release 8/9, also can be the new transformat that LTE-A may introduce, discrete Fourier-spread spectrum-OFDM (Discrete Fourier Transform-Spreading-Orthogonal Frequency DivisionMultiplexing, DFT-S-OFDM) form for example.Fig. 2 has provided a kind of example that adopts DFT-S-OFDM form PUCCH channel simultaneously to transmit CSI information and response message to be transmitted, Fig. 2 has only shown main functional module in this scene, as chnnel coding (Channel Encoding) module, community scrambling (Cell-SpecificScrambling) module, modulation (Modulation) module, off-line Fourier transform (Discrete FourierTransform, DFT) module and inverse-Fourier transform (Inverse Discrete Fourier Transform, IFFT) module, wherein, in each time slot (Slot), by 7 symbols, formed, second and the 6th symbol are frequency pilot sign, five remaining symbols can be used for the transmission of response message to be transmitted, and adopted frequency expansion sequence that a length is 5 to treat response information transmission and carried out spread spectrum in 5 symbols, referring to Fig. 2 spreading factor (Spreading Factor, SF) be 5, frequency expansion sequence is { w0, w1, ..., w4}.

UE can also put the response message b (0) (1) of 2 bits and the bit information of CSI together by predefined rule, then combined coding.The new transformat that the bit information generating after coding may be introduced with LTE release 8/9PUCCH form 2/2a/2b or LTE-A, for example DFT-S-OFDM form transmits.

If above-mentioned uplink information is upstream data, the response message to be transmitted of this 1 bit or 2 bits can transmit by predefined rule multiplexing together with upstream data (multiplexing) on PUSCH.

Further embodiment of this invention also provides a kind of method that simultaneously sends response message to be transmitted and other uplink information under carrier aggregation, comprising:

Step T1: distribute the first channel resource for feeding back response message to be transmitted, distribute second channel resource for feeding back corresponding ascending control information.This ascending control information comprises forward SRI information and/or CSI information, but is not limited to this, also comprises other required control information on up direction.

In above-mentioned steps 12, the response message to a plurality of member carriers of subscriber equipment access, the to be transmitted response message of feedback after logical AND operation.Now, while denying response message in response message, the feedback response message to be transmitted that operation obtains through logical AND is for denying response message, and at this moment, the member carrier correctly having received for those, can introduce some unnecessary PDSCH and again transmit.For fear of the response message of a plurality of member carriers is carried out to logical AND operation, another kind of possible mode is by after the response message combined coding of a plurality of member carriers, for example uses LTE Release 8/9PUCCH form 2/2a/2b channel or DFT-S-OFDM form channel to transmit.

For convenience of description, LTE Release 8/9PUCCH form 1/1a/1b channel is called to basic responder link below; LTE Release 8/9PUCCH form 2/2a/2b channel or DFT-S-OFDM channel are called to expansion responder link.Basic responder link can only feed back lesser amt, the response message to be transmitted of 1 to 2 bit for example; Expansion responder link person can feed back larger amt, the response message to be transmitted of maximum 10 to 20 bits for example.

Consider that the resource that the resource that takies of expansion responder link takies than a basic responder link is many, in order to reduce the shared channel resource expense of feedback response message as far as possible, for feeding back response message to be transmitted, distribute the first channel resource further to comprise: when subscriber equipment only need to feed back response message to be transmitted at least one predetermined member carrier, described distribution the first channel resource is that allocation base should be answered channel resource; When subscriber equipment need to feed back response message to be transmitted at least one member carrier outside described predetermined member carrier, described distribution the first channel resource is to distribute expansion responder link resource.When having distributed expansion responder link resource, subscriber equipment feeds back at the response message of interior all member carriers comprising predetermined member carrier on the expansion responder link distributing.

In LTE-A carrier aggregation technology, during for a plurality of member carrier of user device configuration, can also define a descending main member carrier and a up main member carrier for subscriber equipment.Descending main member carrier can be for wireless link failure monitor and the system message update of subscriber equipment.Up main member carrier can be for the control information of subscriber equipment feeding back uplink.DCI to a downlink member carrier transmission, both can indicate the PDSCH of this downlink member carrier to transmit, and also can indicate the PDSCH transmission of other downlink member carrier.To a downlink member carrier, if reserved basic responder link at up main member carrier for the DCI of its transmission, this downlink member carrier is called to the downlink member carrier with up main member carrier system relationship.Described predetermined member carrier is, descending main member carrier or be configured in descending main member carrier transmission DCI member carrier or with the downlink member carrier of up main member carrier system relationship.

When only when described predetermined member carrier receives DCI and PDSCH transmission, subscriber equipment only need to feed back response message to be transmitted to described predetermined member carrier; Or, in DCI, for example, by certain way (increasing by 1 bit), come whether equipment for indicating user is current only need to feed back response message to be transmitted to described predetermined member carrier, first channel that now also can distribute by indication is basic responder link or expands whether the indirect equipment for indicating user of responder link is current only need to feed back response message to be transmitted to described predetermined member carrier.

Described ascending control information comprises forward SRI information and/or CSI information.When described ascending control information comprises forward SRI information, described distribution second channel resource comprises distributes SR channel resource; When described ascending control information comprises CSI information, described distribution second channel resource comprises distributes CSI channel resource.For LTE-A system, SR channel can be LTE Release 8/9 PUCCH form 1/1a/1b channel, and CSI channel can be LTE Release 8/9PUCCH form 2/2a/2b channel or DFT-S-OFDM channel.

When subscriber equipment only feeds back response message to be transmitted, at the first channel resource distributing, send response message to be transmitted; When subscriber equipment only feeds back forward SRI information, at the SR channel resource distributing, send forward SRI information; When subscriber equipment only feeds back CSI information, at the CSI channel resource distributing, send CSI information.

Step T2: when subscriber equipment only need to feed back response message to be transmitted and feed back described ascending control information simultaneously at least one predetermined member carrier, response message to be transmitted and described ascending control information are sent after multiplexing in described second channel resource; When subscriber equipment need to feed back response message to be transmitted and feed back described ascending control information simultaneously at least one member carrier outside described predetermined member carrier, response message to be transmitted and described ascending control information are sent after multiplexing on described the first channel resource.

As previously mentioned, when only when described predetermined member carrier receives DCI and PDSCH transmission, or when in DCI, indication only need to be fed back response message to be transmitted to described predetermined member carrier, subscriber equipment only need to feed back response message to be transmitted to described predetermined member carrier.

For LTE-A system, when subscriber equipment only need to feed back response message to be transmitted and feed back described ascending control information simultaneously described predetermined member carrier, according to the mode of LTE Release 8/9, response message to be transmitted and described ascending control information are sent after multiplexing in described second channel resource.If described ascending control information is forward SRI information, response message to be transmitted directly can be sent at the SR channel resource distributing so; If described ascending control information is CSI information, response message to be transmitted can be placed on so on the frequency pilot sign of CSI channel resource of distribution and send, or will response message to be transmitted and CSI information consolidation coding after at the CSI channel resource distributing, send; If described ascending control information comprises forward SRI information and CSI information simultaneously, can not send CSI information, response message to be transmitted is directly sent at the SR channel resource distributing.Now, need not for feeding back that basic responder link resource that response message to be transmitted distributes is vacant.

When subscriber equipment need to feed back at least one member carrier outside described predetermined member carrier response message to be transmitted and during simultaneously with the described ascending control information of feedback, on described the first channel resource, send after response message to be transmitted and described ascending control information is multiplexing in a certain way.If described ascending control information is forward SRI information, SRI information can be placed on the frequency pilot sign of the first channel resource of distribution and sends, or will after SRI information and response message combined coding to be transmitted, on the first channel resource distributing, send; If described ascending control information is CSI information, can will response message to be transmitted and CSI information consolidation coding after on the first channel resource distributing, send, or treat response information transmission and do logical AND operation and obtain the response message to be transmitted of 1 bit to 2 bit and be placed on the frequency pilot sign of the first channel resource of distribution sending, after CSI information coding, on the first channel resource distributing, sending simultaneously; If described ascending control information comprises forward SRI information and CSI information simultaneously, can not send CSI information, forward SRI information and response message are sent after multiplexing on the first channel resource distributing, or will SRI information, on the first channel resource distributing, send after response message and CSI information consolidation coding.Now, need not for feeding back that second channel resource that described ascending control information distributes is vacant.
