It should be understood that, technical solution of the present invention, it can be applied to the various communication systems based on various wireless communication protocols, such as: global system for mobile communications (Global System of Mobile communication, GSM), wideband code division multiple access (Wideband Code Division Multiple Access, W-CDMA) system, TD SDMA (Time Division-Synchronous Code Division Multiple Access, TD-SCDMA) system, CDMA (Code Division Multiple Acce Ss, CDMA) system, long term evolution (Long Term Evolution, LTE) system, Universal Mobile Communication System (Universal Mobile Telecommunications System,) or global interconnection inserting of microwave (Worldwide Interoperability for Microwave Access, WiMax) system etc. UMTS.

Hereinafter, the part term in the application is explained, in order to those skilled in the art understand that.

1), terminal, also referred to as user equipment (User Equipment, UE), are a kind of equipment for providing a user voice and/or data connectivity, for example, handheld device, mobile unit etc. with wireless connecting function.Common terminal for example, mobile phone, tablet computer, laptop, palm PC, mobile internet device (mobile internet device, MID), wearable device, such as smartwatch, Intelligent bracelet, pedometer etc..

2), wireless access network (Radio Access Network, RAN) equipment is a kind of equipment that terminal is linked into wireless network, also referred to as base station, including but not limited to: evolved node B (evolved Node B, eNB), radio network controller (radio network controller, RNC), node B (Node B, NB), base station controller (Base Station Controller, BSC), base transceiver station (Base Transceiver Station, BTS), Home eNodeB (such as, Home evolved NodeB, or Home Node B, HNB), Base Band Unit (BaseBand Unit, BBU).In addition, it can include Wifi access point (Access Point, AP) etc..

3), " multiple " refer to two or more."and/or" describes the incidence relation of affiliated partner, indicates may exist three kinds of relationships, for example, A and/or B, can indicate: individualism A is deposited simultaneously In A and B, these three situations of individualism B.Character "/" typicallys represent the relationship that forward-backward correlation object is a kind of "or".

Fig. 1 is the schematic diagram of a communication system of the embodiment of the present invention.The communication system includes base station 110.Terminal 120 accesses wireless network by base station 110, and communicates by wireless network access outer net (for example, internet) or with other terminals.Fig. 1 shows the scene that base station 110 and terminal 120 communicate under a kind of CA scene, and base station 110 is that terminal is configured at least two serving cells, here for two, respectively main plot (Pcell) and secondary cell (Scell).Wherein, the carrier wave of Pcell is PCC, and the carrier wave of Scell is SCC.Here by taking Pcell and Scell is the cell under same base station as an example, Pcell and Scell may be the cell under different base station.In addition, the quantity of Scell may be multiple.

In the examples below, it is described, i.e., is described by taking a SCC as an example so that two CC polymerize as an example, the case where more than one SCC, the realization of other SCC is similar therewith, repeats no more.

When terminal and base station are communicated, terminal needs to send control information to base station so that base station reference carries out the transmission of uplink and downlink data.The control information is ascending control information (Uplink Control Information, UCI).UCI specifically includes that scheduling request (Scheduling Request, SR)；Hybrid automatic repeat-request (Hybrid Automatic Repeat Request, HARQ) feedback, such as ACK or NACK, i.e., the HARQ feedback downlink data sent on PDSCH carried out；Channel state information (Channel State Information, CSI), it such as may include channel quality instruction (Channel Quality Indicator, CQI), pre-coding matrix instruction (Precoding Matrix Indication, PMI), one or more of order instruction (Rank Indication, RI).

The transmission channel of UCI includes Physical Uplink Control Channel (Physical Uplink Control Channel,) and Physical Uplink Shared Channel (Physical Uplink Shared Channel PUCCH, PUSCH), when terminal has upstream data to send and PUSCH resource is assigned, terminal is sent to base station by PUSCH using UCI as with road information；When terminal does not have upstream data transmission, UCI is sent to base station by PUCCH by terminal.That is, terminal preferentially uses PUSCH transmission UCI when base station scheduled PUSCH, when not having PUSCH scheduling, terminal transmits UCI using PUCCH.

With continued reference to FIG. 2, being likely to carry out PUSCH scheduling on PCC and SCC when introducing uplink CA.It is currently that the preferential PUSCH using PCC sends UCI；When PCC does not dispatch PUSCH, and SCC dispatches PUSCH, UCI is sent using the PUSCH of SCC；As PCC and SCC all no scheduling PUSCH, UCI is sent using the PUCCH of PCC.However, SCC is not aware that on PCC whether scheduled PUSCH, so when SCC demodulates PUSCH, in this case it is not apparent that PUSCH UCI whether is carried, therefore can not determine demodulation mode, is unfavorable for the demodulation of PUSCH on SCC.

Based on the above issues, the embodiment of the present invention proposes a kind of scheme, to reduce the uncertainty for the channel for feeding back UCI.Such as, (Frequency Division Duplexing is supported at the same time, FDD) with time division duplex (Time Division Duplexing, TDD in communication system), PCC works in fdd mode, SCC work is in tdd mode, by reporting in resource distribution to downlink subframe or special subframe for the UCI on SCC, since UCI is only capable of reporting by sub-frame of uplink, therefore this configuration is so that the UCI on SCC can not be reported by the PUSCH of SCC, therefore UCI is only capable of reporting by the PUSCH or PUCCH of PCC.Therefore, SCC demodulates PUSCH without the format for carrying UCI, and PCC knows whether PUSCH scheduled, it can therefore be appreciated that being that demodulation PUSCH obtains UCI or demodulation PUCCH obtains UCI.

Below with reference to Fig. 3, above scheme is described.Fig. 3 shows a kind of schematic flow chart of communication means 300 for uplink CA according to an embodiment of the present invention.This method 300 can be applied to support the communication system of uplink CA, the communication system supports tdd mode and fdd mode, the communication system includes the first up-link carrier and the second up-link carrier, first up-link carrier and second up-link carrier use different dual-modes, such as first up-link carrier use fdd mode, the second up-link carrier use tdd mode.As shown in figure 3, this method 300 includes:

S310, base station determine the configuration information of UCI, which includes resource allocation information, which is used to indicate the resource of transmission UCI, which is located at downlink subframe and/or special subframe in tdd mode；

S320, base station sends the configuration information to terminal, and then terminal receives the configuration information.

S330, terminal determine that the resource of transmission UCI is located at downlink subframe and/or special subframe in tdd mode according to the configuration information, that is, are located at the downlink subframe and/or special subframe of the second up-link carrier.And downlink subframe and/or special subframe are not used in the transmission of UCI, i.e. UCI can only be transmitted by sub-frame of uplink, therefore terminal can determine and transmit UCI on the first up-link carrier, i.e. execution following steps:

S340, terminal transmit UCI on the first up-link carrier.

It should be noted that the above base station is the base station where the second up-link carrier.And first up-link carrier and the base station where the second up-link carrier may be the same or different.

As it can be seen that in the embodiment above, the resource distribution of UCI can will be transmitted on special subframe and/or downlink subframe in the base station of tdd mode by working, so that UCI can only be reported by the up-link carrier to work in fdd mode.In this way, reducing the uncertainty of the channel of feedback UCI, is conducive to the demodulation of UCI, improves efficiency of transmission, reduce the complexity of processing.

It should be understood that the configuration information in the embodiment of the present invention can be carried in wireless heterogeneous networks (Radio Resource Control, RRC) signaling, or it is carried in other signalings, this is not construed as limiting.

Optionally, the first up-link carrier is PCC, and the second up-link carrier is SCC.

For tdd mode, what transmitting-receiving was all completed in the different time of same frequency range, i.e. uplink and downlink distinguishes in time, LTE system can support 7 kinds of different ascending-descending subframes configurations, specifically can be by broadcast message notice terminal using which kind of, and specific configuration is as shown in table 1, wherein D indicates downlink subframe, U indicates that sub-frame of uplink, S indicate special subframe

The different uplink-downlink configuration of 1 LTE TDD system of table

For fdd mode, uplink and downlink has independent frequency point to come using then the subframe of each radio frames, which can be used for uplink, can be used for downlink transfer.The sub-frame configuration of fdd mode is as shown in table 2, and wherein D indicates the subframe that can be used for downlink transfer, and U indicates the subframe that can be used for uplink.

The uplink-downlink configuration of 2 LTE FDD system of table

Embodiment in order to more clearly describe the present invention is described below in conjunction with the specific example in Fig. 4.

Fig. 4 is a schematic diagram of a scenario using the embodiment of the present invention.The scene that scene in Fig. 4 is FDD+TDD.It here is fdd mode with PCC, SCC is illustrated for tdd mode.It should be noted that this is intended merely to that those skilled in the art is helped to more fully understand the embodiment of the present invention, the range for the embodiment that is not intended to limit the present invention.Wherein, the sub-frame configuration of TDD is using the configuration 2 in table 1 above.As shown in figure 4, for the subframe of TDD: subframe 0,3,4,5,8,9 is downlink subframe, and subframe 1 and subframe 6 are special subframes, cannot report UCI；Subframe 2 and subframe 7 are sub-frame of uplink, can report UCI.For the subframe of PCC: subframe 0-9 can report UCI.In embodiments of the present invention, for the subframe of TDD, the resource for reporting UCI can only be configured in advance by RRC signaling On the downlink subframe and special subframe (i.e. subframe 0,1,3,4,5,6,8,9) of TDD, and forbid configuring the resource for transmitting UCI in subframe 2 and subframe 7.In this way, when terminal needs to transmit UCI, the sub-frame transmission of FDD (corresponding PCC) can only be passed through, that is the base station where SCC distributes the subframe for carrying out PUSCH scheduling in these subframes (i.e. subframe 0,1,3,4,5,6,8,9), UCI is avoided to report by the subframe of TDD (corresponding SCC), it is possible to the uncertainty reported from PCC and SCC to reduce terminal, can reduce the complexity of processing, improves transmission performance.Here, it gives the correct time in subframe of the UCI by FDD, when no PUSCH is dispatched on PCC, PUCCH can be dispatched, so that terminal transmits UCI on PUCCH.

In other words, base station is by giving the resource distribution of transmission UCI on the downlink subframe and special subframe in tdd mode, it is transmitted in a disguised form define UCI by the PUSCH or PUCCH of FDD, that is UCI can only be reported using the PUSCH or PUCCH of PCC, it reduces terminal and is possible to the uncertainty reported from PCC and SCC when reporting UCI, transmission performance is improved, can reduce the complexity of processing.

It should be understood that being to be illustrated in Fig. 4 by taking the uplink-downlink configuration 2 of the tdd mode in LTE as an example, the embodiment of the present invention can be applied to any uplink-downlink configuration in tdd mode, be not construed as limiting to this.

It should also be understood that being with PCC work in Fig. 4 in fdd mode, SCC work is illustrated for tdd mode, and the embodiment of the present invention can also be applied to SCC work the case where tdd mode, PCC work are in fdd mode, is not construed as limiting to this.

Specifically, for PCC work in tdd mode, SCC work in fdd mode, its thought is similar: will transmit the resource distribution of UCI on the special subframe and downlink subframe of tdd mode (PCC), similarly, UCI can only be transmitted by the subframe of fdd mode (corresponding SCC), and difference is finally using the PUSCH transmission UCI on SCC.In this way, reducing terminal is possible to the uncertainty reported from PCC and SCC when reporting UCI, so that SCC is demodulated by the way of carrying UCI in demodulation, efficiency of transmission is improved.

From the above description it is known that, UCI includes the information such as HARQ feedback information and CSI, these information are for down channel, such as HARQ feedback, it is the feedback for the reception condition that data on down channel are transmitted, CSI is the feedback of the measurement situation to down channel quality.Therefore, in downlink CA Scene under, the UCI reported in above embodiments may include for each polymerization descending carrier UCI.In addition, the report cycle of CSI can be further configured for reporting for CSI, so that terminal reports CSI according to the report cycle.

Optionally, the above configuration information can also include period assignment information, which is used to indicate the report cycle of UCI, wherein the subframe sum of special subframe and downlink subframe is not less than number of subframes needed for transmission UCI in the report cycle of UCI.Here number of subframes needed for transmitting UCI is related with the quantity for the descending carrier polymerizeing, for example has 5 CC polymerizations in the user equipment downlink, and the UCI of each downlink CC, which is reported, occupies a subframe, then needs 5 subframes in total.The report cycle of the UCI of base station configuration at this time should include at least 5 subframes, by taking a subframe 1ms as an example, then include at least 5ms.

That is, base station can indicate the report cycle of UCI by configuration information, wherein, the condition that the report cycle needs of UCI meet is: the subframe sum of special subframe and downlink subframe is not less than number of subframes needed for transmission UCI in the report cycle of UCI, number of subframes needed for the UCI transmission in order to meet the descending carrier of polymerization.

Optionally, this method 300 can also include:

When the number of subframes needed for determining that the subframe sum is less than the UCI transmission of the descending carrier of polymerization, increase the report cycle of UCI.

Specifically, base station can also in the report cycle of UCI the subframe of downlink subframe and special subframe sum be compared between the variable number for needing to feed back UCI in descending carrier polymerize, determined whether according to comparison result increase UCI report cycle.If the subframe sum of downlink subframe and special subframe is less than the descending carrier number that need to feed back UCI in the report cycle of UCI, base station can according to need to increase the report cycle of UCI.For example, still illustrating in conjunction with the sub-frame configuration 2 of the TDD in Fig. 4, if the UCI of each DL CC is required to occupy a subframe for the scene of DL 5CC (5 descending carrier polymerizations), then need to occupy 5 subframes；At this time, if the report cycle of UCI is 5ms, and the number of the special subframe and downlink subframe (subframe 0,1,3 and 4) distributed in 5ms at this time is 4, this means that only 4 subframes can send UCI, in this way, can not meet the demand that DL 5CC needs to occupy 5 subframes, this when, just need to elongate the report cycle of UCI, to meet the subframe demand of DL 5CC.Such as, base station can elongate the report cycle of UCI to 10ms from 5ms, and in this case, the number of the special subframe and downlink subframe (subframe 0,1,3,4,5,6,8,9) that distribute in 10ms is 8, in this case, so that it may meet the UCI feedback needs of DL 5CC Occupy the demand of 5 subframes.

It should be noted that, if the subframe sum of downlink subframe and special subframe is greater than the descending carrier number that need to feed back UCI in the report cycle of UCI, number of subframes needed for the report cycle of UCI can satisfy the UCI transmission of the descending carrier of polymerization at this time, then base station can choose the report cycle for not needing to increase UCI.Certainly, base station can also determine whether need to change the report cycle of UCI as the case may be, be not construed as limiting to this.

It should be understood that, here it is only illustrated for elongating the report cycle of UCI from 5ms to 10ms, the practical application of report cycle in to(for) UCI is not restricted, and for its period to increase to which kind of degree also there is no limit, as long as meet demand and rationally be all acceptable, this is not limited by the present invention.

It should also be understood that in embodiments of the present invention, numbering " first " or " second " ... and being intended merely to distinguish different objects, such as distinguish different carrier waves, limiting the invention.

Forgoing describing to configure in the embodiment of the present invention about base station for UCI reports resource to be not used in the technical solution for sending the subframe of UCI to TDD, to reduce the uncertainty for the channel for feeding back UCI, the demodulation for being conducive to UCI, improves efficiency of transmission, reduces the complexity of processing.It optionally, can also be by solving the problems, such as this otherwise.The technical solution for solving the problems, such as this in the embodiment of the present invention by hiding mechanism is described more fully below.

Optionally, as one embodiment, the present invention also provides a kind of communication means for uplink CA.Specifically referring to FIG. 5, it illustrates the schematic flow charts of the communication means 500 according to another embodiment of the present invention for uplink CA.This method 500 is applied to support the communication system of uplink CA, which includes uplink PCC and uplink SCC, and this method 500 is executed as the base station where uplink SCC.As shown in figure 5, this method 500 includes:

S510 obtains terminal to the upper time signal machine of UCI；

S520 carries out PUSCH scheduling according to time signal machine on this on uplink SCC, wherein the subframe for PUSCH scheduling does not include the corresponding subframe of time signal machine on this.

Above step S520 could alternatively be base station and dispatch in upper time signal machine corresponding subframe of the terminal to UCI without PUSCH.

It can be seen that, in the embodiment above, when the sub-frame of uplink of the upper time signal machine of UCI and uplink SCC collide, scheduling is hidden on the sub-frame of uplink of uplink SCC in base station, i.e., dispatches without PUSCH, and such UCI is reported to base station by uplink PCC, reduce the uncertainty of the channel of feedback UCI, the demodulation for being conducive to UCI, improves efficiency of transmission, reduces the complexity of processing.

Base station where PCC can configure the upper time signal machine of UCI, and when configuring SCC, report moments notice to the base station where SCC the UCI, therefore the base station where SCC can obtain the upper time signal machine of UCI.

In embodiments of the present invention, upper time signal machine refers to opportunity of the UCI when being reported in subframe, terminal needs to report in some subframe UCI (including on each carrier wave CC of downlink, any one CC needs the UCI fed back), i.e. upper time signal machine can correspond to a subframe numbers, for example, terminal can report UCI in 2 work song frames in tdd mode sub-frame configuration 2, then the 2 work song frame can be understood as the corresponding subframe of time signal machine thereon.

Below with reference to Fig. 6, it is described in detail.As shown in fig. 6,2 work song frames are configured as the upper time signal machine of UCI, PUSCH is not dispatched on the 2 work song frame in the base station where SCC, therefore UCI is reported to base station by PCC.

Currently, in uplink CA, in two up-link carriers of polymerization, in two symbols sent simultaneously, one of symbol will send detection reference signal (Sounding Reference Signal, SRS), and be PUSCH on another symbol, then SRS is not sent.

However, under the scene of FDD+TDD uplink CA, the up-link carrier polymerizeing includes work in the up-link carrier of fdd mode and works in the up-link carrier of tdd mode, when FDD subframe x (indicating subframe number) has PUSCH scheduling, then the SRS on TDD subframe x cannot then be sent, such as shown in fig. 7, the SRS in TDD subframe 1 (corresponding to the last symbol in subframe 1 in figure) cannot be sent because of the PUSCH scheduling in FDD subframe 1.And the wave beam forming of TDD depends on the out-hole run of SRS.Therefore, not sending SRS will affect wave beam forming, and then influence the communication performance of downlink, cause efficiency of transmission low.

One embodiment of the application considers this problem, proposes a kind of communication means for uplink CA, and for this method when TDD subframe corresponds to the transmission opportunity of SRS, FDD subframe hides PUSCH scheduling.In this way, terminal can send SRS, it is possible thereby to complete the wave beam forming of TDD, efficiency of transmission is improved.

Specifically referring to FIG. 8, it illustrates the schematic flow charts of the communication means 800 for uplink CA according to yet another embodiment of the invention.This method 800 is applied to support the communication system of uplink CA, the communication system includes the first up-link carrier and the second up-link carrier, first up-link carrier uses fdd mode, and the second up-link carrier uses tdd mode, and this method 800 is executed as the base station where the first up-link carrier.As shown in figure 8, this method 800 includes:

S810 obtains terminal to the transmission opportunity of SRS；

S820 carries out PUSCH scheduling according to the transmission opportunity on the first up-link carrier, wherein uses In the PUSCH scheduling subframe do not include the transmission opportunity corresponding subframe.

Above step S820 could alternatively be base station and dispatch in transmission opportunity corresponding subframe of the terminal to SRS without PUSCH.

As it can be seen that in the embodiment above, when the PUSCH collision for sending opportunity and FDD of the SRS of TDD, scheduling is hidden in the corresponding subframe of SRS sending time in the base station of FDD, i.e., dispatches without PUSCH.In this way, terminal discovery does not have PUSCH to need to send in the sending time of SRS, therefore SRS can be normally sent, be conducive to the wave beam forming of TDD, improve efficiency of transmission.

In general, base station can configure the transmission opportunity of SRS for terminal, therefore base station can obtain the transmission opportunity of the SRS when needed and be used.The transmission opportunity can usually be configured as the base station where PCC, and notify the base station where SCC.

It should be understood that the related embodiment of mechanism is hidden in of the invention taking, application scenarios are not limited to the uplink CA scene of figure TDD+FDD, can also be not construed as limiting applied to the uplink CA scene of TDD+TDD or the uplink CA scene of FDD+FDD to this.

Currently, the authorization of N+4 sub-frame of uplink is handed down to terminal in N work song frame, wherein N is nonnegative integer.The issuing for demodulation management frame of 2 (L2) of layer to layer 1 (L1, i.e. physical layer) receive in 4ms completion with L1 layer of preparation with the upstream data that sends in N+4 work song frame to terminal and control information (for example, UCI) and demodulate.After introducing uplink CA, the scheduling of PCC and the same subframe of SCC carry out simultaneously.When SCC uplink scheduling terminal, the scheduling result on PCC is also unknown.Thus there are some problems, for example, L2 layers to L1 layers issue demodulation management frame when do not know whether the UCI (e.g., including ACK NACK) of terminal feeds back on the road PUSCH Shang Sui of SCC.Therefore, in the prior art, the demodulation on PCC is just carried out after the dispatch situation for knowing SCC.This method be not particularly suited for L2 L1 the compact system of processing delay, the biggish system of the time delay not also being suitable between PCC and SCC seriously affects CA performance.

In view of the above problems, the invention proposes a solution, in the up-link carrier of polymerization, either PCC or SCC, the up channel of oneself is demodulated according to not having progress PUSCH scheduling on other up-link carriers, that is to say, that demodulate up channel in the way of carrying UCI.When the up-link carrier is PCC, the up channel of demodulation can be PUCCH or PUSCH；When the up-link carrier is SCC, the up channel of demodulation can be PUSCH.But other up-link carriers may actually scheduled PUSCH, and terminal is actually the UCI fed back on the PUSCH of other up-link carriers, therefore, at this time if it is wrong for carrying out processing according to the UCI demodulated, therefore, it can be according to the dispatch situation of other up-link carrier upper signal channels, to judge whether the UCI demodulated is correct.This programme is suitable for HARQ feedback information in UCI, i.e. ACK/NACK.

Specifically referring to FIG. 9, it illustrates the schematic flow charts of the communication means 900 according to another embodiment of the present invention for uplink CA.This method is applied to support the communication system of uplink CA, which includes the first up-link carrier and the second up-link carrier, as shown in figure 9, this method 900 includes:

S940, the first base station obtain the channel dispatch situation of second base station from second base station, and according to the channel dispatch situation, determine the validity of first feedback information and second feedback information.

It can be seen that, first base station can demodulate first physical uplink channel in the way of carrying ascending control information UCI on first physical uplink channel to obtain the first feedback information, and obtain the second feedback information, the validity of the first feedback information He second feedback information can be determined according to the channel dispatch situation of the second base station.In this way, can be according to the dispatch situation of other up-link carrier upper signal channels, to judge whether the UCI demodulated is correct.

Optionally, which is main member carrier PCC, which is secondary member carrier SCC, and

In other words, in the present embodiment, up channel is demodulated premised on up-link carrier all carries UCI, such as, PUSCH is demodulated for SCC, PUCCH or PUSCH demodulated for PCC, it is specific demodulate PUSCH or PUCCH i.e. premised on the PUSCH of PCC or PUCCH carries UCI, and PUSCH is demodulated premised on the PUSCH of SCC carries UCI.In this way, feedback information can be obtained in time, but terminal has actually only passed through the result that the channel that wherein some channel uploads feedback information, therefore only really carries feedback information demodulates and has been available, other feedback informations are disabled.Therefore, base station is according to demodulation result and actual schedule as a result, to confirm that the UCI demodulated on which final up-link carrier is effective.And actual schedule is the result is that there are many possibilities, for example have PUSCH on the first up-link carrier and the second up-link carrier；Or first have PUSCH on up-link carrier, does not have PUSCH on the second up-link carrier；Or first do not have PUSCH on up-link carrier, has PUSCH on the second up-link carrier.Wherein, first base station according to demodulation result and actual schedule as a result, determine feedback information validity, mainly include following situations (be with the first up-link carrier below for PCC, the second up-link carrier be SCC for be illustrated):

A. if having PUSCH scheduling on PCC, when having PUSCH on SCC, it is determined that the ACK NACK with road feedback of PUSCH on SCC is invalid and the ACK NACK of the road PUSCH Shang Sui feedback on PCC is effective；

B. if without PUSCH on PCC, when having PUSCH on SCC, it is determined that the ACK NACK with road feedback of the PUSCH on SCC is effective and the ACK NACK of the road PUCCH Shang Sui feedback on PCC is invalid；

C. if without PUSCH on PCC, when the upper no PUSCH of SCC, it is determined that the ACK NACK of the road the PUCCH Shang Sui feedback on PCC is effective.

Here, the second up-link carrier is similar with the processing operation of the first up-link carrier, for sake of simplicity, not repeating this.

It therefore, can be according to the dispatch situation of other up-link carrier upper signal channels, to judge whether the UCI demodulated is correct.HARQ feedback information of this programme suitable for UCI, i.e. ACK/NACK.Into one Step ground can be determined effectively to feed back instruction information in the case where time delay is compact, and not influence the processing capacity and specification of product.
