A kind of data repeating method for running on the above-mentioned network architecture is provided in the present embodiment, and Fig. 2 is according to this hair The flow chart of the data repeating method of bright embodiment, as shown in Fig. 2, the process includes the following steps:

There is at least one following scenario described during sending transport block data to terminal UE in step S202, base station: described There is punching transmission in the transmission block TB data that base station is sent to the UE；The base station sends the transport block data to the UE Some or all of using subband is to allow to punch the subband transmitted；The base station configures the UE and monitors punching instruction information. You need to add is that the punching instruction information in present specification is that base station selected property is sent, it is not necessary to transmission.Example Such as, punching instruction information is the optional transmission in base station, that is to say, that although there is punching transmission in some cases in base station, Base station can not send opening instruction information.Compare typically, in punching transmission, the data influence of the position of punching for UE It is smaller, or punching position it is smaller when, base station do not send punching instruction information.

Step S204, after there is at least one described situation, the base station receive the UE feedback ACK or Nack message, wherein when the base station receives ACK information, the base station determines that situation belonging to UE decoding is the One situation or the second situation.Wherein, the first situation includes the UE to the code block in the transport block data comprising being perforated All CB data including CB are successfully decoded；Second situation includes that the UE is perforated in the transport block data except described All CB data except CB are successfully decoded.You need to add is that the first above-mentioned situation may include UE to transport block data In be successfully decoded comprising all CB data including code block that are perforated, and/or, UE determines that the decoded CRC check of transmission block TB is logical It crosses.

Step S206, the base station send to the UE according to the ACK or nack message and retransmit data.

Through the above steps, occur during base station sends transport block data to terminal relevant about punching transmission After one of predetermined situations, the base station receives the ACK or nack message of the UE feedback, wherein receives in the base station When to ACK information, the base station determines that situation belonging to the UE decoding is the first situation or second according to the ACK information Situation determines whether to retransmit data later according to mode corresponding with the first situation or the second situation, and sends and retransmit number According to.By adopting the above technical scheme, it solves in the related technology when punching transmission occur in the data of transmission, the feedback mechanism of UE is led Base station is caused to retransmit the low problem of data efficiency, when needing to retransmit, base station no longer always retransmits entire transport block data, Ke Yichuan The partial data of the existing punching transmission of output, is greatly reduced re-transmission data volume.

Optionally, the base station determines situation belonging to the UE decoding at least one in the following manner:

It makes an appointment with the UE as the different resource of different situations configuration, wherein the UE is fed back using the resource The ACK information；You need to add is that different situations, that is, above-mentioned two situations, can for UE according to two kinds of situation feeding back ACKs when Configure different resources.

Make an appointment with the UE when sending the ACK information, at the same send for situation belonging to indicating bit and/ Or sequence；You need to add is that the bit and/or sequence are not belonging to ACK information, a ratio can be increased after ACK information Special and/or sequence.

According to the determining affiliated situation of ACK information of at least one following information: whether the base station sends to the UE Punching instruction information；After determining that the base station has sent punching instruction information, the base station determines the UE in feedback institute Whether there is time enough to decode the punching instruction information before stating ACK or nack message.You need to add is that base station is sent Punching instruction information, sending instant of the base station according to punching instruction, UE processing capacity determine at the time of receiving UE and send ACK Whether time enough decoding punching instruction information is had before UE feeding back ACK or NACK, and if there is time enough, then UE can be The CB that is perforated in transport block data can be excluded according to punching instruction information when decoded transport block data, i.e., base station is thought at this time ACK is above-mentioned second situation.Otherwise it is assumed that UE is not received by punching instruction information or beats without enough time to decode Hole indicates information, and UE is decoded to entire transport block data, i.e., is also correctly decoded to the CB that is perforated, and base station determines at this time The ACK of UE is the first situation in above-described embodiment.Certainly, if the not sent punching in base station indicates information, UE is thought in base station The first corresponding situation of the ACK information of feedback.You need to add is that terminal whether have time enough for decode can be Some specific value, this is associated with the processing capacity difference of different terminals.

Optionally, during the base station sends the transport block data to the UE, there is following scenario described: described There is punching transmission in the transport block data that base station is sent to the UE；Alternatively, the base station sends the transmission block to the UE It is to allow to punch the subband transmitted that data, which some or all of use subband,；Alternatively, the base station, which configures the UE, monitors punching Indicate information；Alternatively, the transport block data that the base station is sent to the UE punching transmission occurs and the base station configures The UE monitors punching instruction information；Alternatively, the base station, which sends the transport block data to UE, some or all of uses son Band is to allow to punch the subband transmitted, and the base station configures the UE and monitors punching instruction information；In the case where there is the situation, The base station determines situation belonging to the UE decoding in the following manner: making an appointment and is sending with the UE in the base station When ACK information, while sending the bit and/or sequence for indicating affiliated situation；Alternatively, the base station appoints in advance with the UE It is fixed to feed back the ACK information using agreement resource, wherein the agreement resource for for corresponding resource under the situation, In, the agreement resource includes at least one of: sequence, code word and running time-frequency resource.The supplement needed, in appearance State five kinds of situations for the moment, preset resource feeding back ACK information corresponding with said circumstances can be used in UE, to show to base station Send the situation or background of the ACK information.That is, UE is in above-mentioned five kinds of situations for the moment, UE feeding back ACK information When, while the bit and/or sequence for indicating affiliated situation are sent, further by the value of the bit, or about sequencing Column indicate affiliated situation；If UE is not at above-mentioned five kinds of situations, when UE feeding back ACK information, do not sent simultaneously for indicating The bit and/or sequence of affiliated situation.

Optionally, when there is punching transmission in the CB in the transport block data that the base station is sent to the UE, the base station Determine whether CB is perforated in the following manner: the base station obtains the data volume and the CB total amount of data that the CB is perforated Ratio, wherein determine the ratio be greater than (or being equal to) preset threshold when, determine that the CB is the CB being perforated；True In the case that the fixed ratio is less than or equal to (or being less than) described preset threshold, determine that the CB is not perforated；Alternatively, described CB exist be perforated data when, the base station determines that the CB is the CB being perforated；When the CB is not present and is perforated data, The base station determines that the CB is not perforated.You need to add is that recorded in the present embodiment be two kinds of determinations, one CB whether The mode being perforated, a kind of mode are the ratio-dependents accounted for according to punctured data, another mode is true as long as be perforated as long as It surely is punching CB.

Step 2 retransmits the data to the UE.

According to another embodiment of the invention, a kind of method that data retransmit is additionally provided, this method includes following step It is rapid:

Step 1, terminal UE receive transport block data, according to treaty rule, form ACK or NACK；

Step 2 sends the ACK or NACK.

It is described in detail below with reference to the preferred embodiment of the present invention.

If adjusted after the feedback mechanism based on transmission block (TB) is configured for the TB of business 1 (such as eMBB business) In degree unit (such as slot) when being transmitted, (such as the URLLC industry of sudden timeliness business 2 is transmitted if necessary at this time Business), then punched that (by the UE of the business that is indicated to 1, this refers to the running time-frequency resource information being specifically perforated for business 1 Show that information is referred to as and punch instruction information, occur to send after drilling), the transmission services 2 in the resource being perforated.Then The UE of business 1 is forming feedback information according to the HARQ-ACK of TB rank for TB, and then base station is according to the feedback of the UE of business 1 HARQ-ACK carry out TB re-transmission.Specifically, having 2 OFDM suddenly when the eMBB business of such as UE1 is transmitted in slot Symbol has been perforated, and (assuming that frequency domain has destroyed all frequency domain resources that the eMBB of UE1 is occupied, the frequency domain beyond UE1 is provided sometimes Source range, such as the frequency domain resource of eMBB of multiple UE are perforated), then UE1 receives the TB of the eMBB business, it is decoded, When the CRC check of TB is obstructed out-of-date, UE1 feeds back NACK to base station, and then base station retransmits the TB；When the CRC check of TB passes through, UE1 feeding back ACK is to base station, and then base station no longer retransmits the TB, it is believed that UE1 received correctly the TB.

The efficiency of feedback mechanism and retransmission mechanism based on TB is low, as it is possible that in the CB for including in the TB, quilt The CB (or CBG) of correct decoding is also retransmitted.The feedback mechanism that such case is primarily due to TB rank is configured for, this Under kind mechanism, UE feeds back 1bit only in order to reduce feedback overhead (thinking that the efficiency of feedback information is very high) whether just to describe TB Really, UE feeds back to the information of base station at this time, base station side can not identify in TB those CB be correctly, those CB be it is wrong, So entire TB can only be retransmitted.

For being configured with the feedback mechanism based on TB, the efficiency of re-transmission how is promoted, is that this programme will solve the problems, such as.

Here is the specific embodiment A of the preferred embodiment of the present invention, example A1, example A2, example A3, example A4, example Sub- B, example C, example D, example E.

Specific embodiment A

UE is configured to carry out HARQ-ACK feedback based on TB.UE is given in base station in a scheduling unit (such as slot s lot) The TB of scheduled transmission business 1 (such as eMBB), business 2 (such as URLLC business) needs to transmit suddenly in transmission, and base station is by slot In part OFDM symbol and part physical resource block punched.Fig. 3 is according to the preferred embodiment of the invention punches The transport block data schematic diagram of transmission, as shown in figure 3, eMBB is perforated in transmission in a slot.Punch position when Domain+frequency domain resource is used to transmission services 2.Punch position can occur only at the time-frequency domain resources of the eMBB business of a UE In, it can also occur in the time-frequency domain resources of the eMBB business of multiple UE.

It should be noted that there is at least one following scenario described during sending transport block data to terminal UE in base station: There is punching transmission in the transmission block TB data that the base station is sent to the UE；The base station sends the transmission block to the UE It is to allow to punch the subband transmitted that data, which some or all of use subband,；The base station configures the UE and monitors punching instruction letter Breath；There is punching transmission in the transport block data that the base station is sent to the UE and the base station configures the UE monitoring and beats Hole indicates information；It is to allow to punch to pass that the base station sends the transport block data some or all of to use subband to the UE Defeated subband, and the base station configures the UE and monitors punching instruction information.Illustrate: condition or situation can be regarded as above A kind of trigger condition, but the method that the trigger condition does not directly affect following each embodiment is implemented.Under that is, Method in each embodiment in face can be individually present, and do not depend on above-mentioned condition presence, only have more under trigger condition Good benefit.Namely if there is other conditions occur, the method in each embodiment below still be can be used.

The behavior of base station and UE:

Before UE feeds back the HARQ-ACK of the TB, base station sends punching instruction information to UE for base station.Wherein punching instruction Information describes those resources in the slot and is perforated, such as is described by OFDM symbol and frequency domain information.UE is according to reception Punching indicate information, the time-frequency domain money distributed when being transmitted in conjunction with the modulating-coding rule of the TB, the mapping ruler of TB and TB Source, UE, which can extrapolate which CB in the TB, to be perforated.Base station can similarly extrapolate what each UE at punching was perforated Which specific CB is perforated in TB.

For the TB being perforated, if UE has been correctly decoded all (schools CRC for the CBs not being perforated CBs not being perforated Test and pass through and/or the CRC check of the TB passes through), UE will give base station feedback ACK information；Otherwise, UE feeds back NACK.At this time if The CRC check of TB rank is not passed through (i.e. TB is not properly decoded), but as long as the CBs not being perforated is correctly decoded by UE, UE is at this time with regard to feeding back ACK.Here CB can be substituted by code block group CBG.CBG does not have CRC, all when include in a CBG When the CRC of CBs passes through, it is believed that CBG is properly decoded, and otherwise CBG is considered non-correct decoding.

After the ACK for receiving UE feedback, base station determines that punching instruction information has been sent before feeding back ACK for base station (and leaving the time of the enough decoding punching instruction information of UE for before feeding back ACK), base station side thinks the ACK that UE is fed back at this time Be meant that: the CBs not being perforated in the TB is correctly decoded.Base station retransmits the CB being perforated at this time, without Retransmit entire TB.Base station is able to use Downlink Control Information (DCI) format identical with initial transmission at this time, in order to UE inspection Survey DCI；Other DCI formats also can be used in base station, but other described DCI formats are to have been arranged, it can be by above-mentioned thing It is reused after part triggering by base station, i.e., base station default is using other described DCI formats when above-mentioned feedback, re-transmission occur, in this way UE is convenient for detection DCI.

After base station receives the NACK of UE feedback, base station, which is then thought also to have in the CBs not being perforated at this time, is not translated correctly The CB of code, base station retransmits entire TB at this time.Note that for NACK, whether base station is without necessarily referring to sending out before UE feeds back NACK Sent punching instruction information (certainly, base station can also with reference to whether UE feed back NACK before has sent punching instruction information, but It is to have little significance, so here without obligating).

It needs to illustrate:

If 1) CB is perforated, but a small amount of data of this CB are only destroyed, this general CB can quilt By encoding and decoding gain, correct decoding result is obtained；The more data if this CB has been struck off, this general CB will It cannot be properly decoded.In NR system, CB in TB unlike supporting CB to carry out time domain intertexture in TB in LTE system, so When being punched according to OFDM symbol, in NR system by occur continuously destroying one or more CB data (and in LTE system, if Punching occurs, and actually punch position is composed of the low volume data of multiple CB), this will lead to occurs once punching, The serious CB that is perforated cannot obtain correct decoding result by encoding and decoding gain.It summarizes are as follows: since CB is in TB in NR system Interweave without time domain, so the CB maximum probability being perforated cannot be correctly decoded, i.e., the TB maximum probability is anti-after punching occurs Present NACK's.

2) when above-mentioned punching occurs, it is possible to will appear part CB and only be perforated low volume data, these CB are also big What probability can be properly decoded.For these CB, simple processing is that these CB belong to the CB being perforated, and be not belonging to not by The CB of punching.Although it is some to do so low efficiency, processing will become simple, and compared with the prior art, retransmission efficiency is still It is significantly improved.Preferably for these CB, reasonable threshold value or ratio, the i.e. number that CB is perforated are obtained by emulation It still can be correctly decoded according to when being less than (being equal to) door restrict or ratio, then these CB belong to the CB not being perforated, without belonging to In the CB of punching.

In above-mentioned specific embodiment A1, by designing the particular feedback condition of ACK, reduce the feelings for retransmitting entire TB Condition improves the efficiency of re-transmission, and the expense without increasing feedback information.

Specific embodiment A1

UE is configured to carry out HARQ-ACK feedback based on TB.UE is given in base station in a scheduling unit (such as slot s lot) The TB of scheduled transmission business 1 (such as eMBB), business 2 (such as URLLC business) needs to transmit suddenly in transmission, and base station is by slot In part OFDM symbol and part physical resource block punched.Such as illustrated in Fig. 3 in a slot, eMBB is being passed It is perforated when defeated.Time domain+frequency domain resource of punch position is used to transmission services 2.Punch position can occur only at a UE EMBB business time-frequency domain resources in, can also occur in the time-frequency domain resources of the eMBB business of multiple UE.

Before UE feeds back the HARQ-ACK of the TB, base station does not send punching instruction information (alternatively, base station is sent out to UE for base station Punching instruction, but UE has little time to decode).Wherein, punching indicates that information describes those resources in the slot and is perforated.

For the TB being perforated, if UE has been correctly decoded all CBs (and/or the CRC check of the TB passes through), UE will be given Base station feedback ACK information；Otherwise, UE feeds back NACK.

After the ACK for receiving UE feedback, base station is determined before feeding back ACK and/or NACK for base station, punching instruction information Do not sent (or sent but can not be decoded in time before UE feeding back ACK punching instruction information), base station side think UE this When the ACK that feeds back and/or NACK be meant that: ACK is that the TB is correctly decoded, and NACK is that the TB is not correctly decoded.This Shi Jizhan is able to use Downlink Control Information (DCI) format identical with initial transmission, in order to which UE detects DCI；It base station can also To use other DCI formats, but other described DCI formats are to have been arranged, it can by above-mentioned event trigger after by base station It reuses, i.e., above-mentioned feedback retransmits default other DCI formats described in base station when occurring, and such UE is convenient for detection DCI.

It needs to illustrate:

2) when above-mentioned punching occurs, it is possible to will appear part CB and only be perforated low volume data, these CB are also big What probability can be properly decoded.For these CB, simple processing is that these CB belong to the CB being perforated, and be not belonging to not by The CB of punching.Although it is some to do so low efficiency, processing will become simple, and compared with the prior art, retransmission efficiency is still It is significantly improved.In addition, obtaining reasonable threshold value or ratio, the i.e. data that CB is perforated by emulation for these CB It still can be correctly decoded when less than (being equal to) threshold value or ratio, then these CB belong to the CB not being perforated, and are not belonging to The CB of punching.

Specific embodiment A2

Based on example A and A1, actually example A and example A1 can be also used in combination.It mainly describes below differentiated Content, other content combination example A and A1.

In conjunction with example 1, when the punch position in the slot s lot where business 1 is smaller, this punching position is thought in base station (i.e. the TB and/or CBs for the position that is perforated in the slot still can when setting the decoding that will not influence TB and/or CBs in the slot It is correctly decoded), base station can not send punching instruction information (before UE feeding back ACK and/or NACK, it is understood that be Base station has sent punching instruction information but the limited decoding punching instruction not before feeding back ACK and/or NACK of UE processing capacity Information.UE processing capacity reports, and base station is known.However, there remains explanation, punching instruction information is one Public information after slot is perforated, may influence the data of multiple UE, but the processing capacity of difference UE is different, that is to say, that The slot that base station sends punching instruction information is determining, but the UE of different disposal ability is in oneself feeding back ACK and/or NACK (slot of each UE feeding back ACK and/or NACK are also not necessarily identical) before, what is had can be successfully decoded punching instruction information, have Punching instruction information cannot be successfully decoded), then UE and base station are handled according to example A1；If punch position meeting is thought in base station When causing TB and/or CBs in the slot that cannot be correctly decoded (i.e. TB and/or CBs in the slot cannot be correctly decoded), Base station can be sent before UE feeding back ACK and/or NACK punching instruction information (refer to base station have sent punching instruction information and UE has enough time decoding punching instruction information before feeding back ACK and/or NACK), then UE and base station according to example A at Reason.

The position that punching instruction information is sent, it is general there are two types of (discussing do not determine using any), the first It is punching instruction information is sent at the end of slot, be for second punching instruction information starts to send out in slot It send.If it is second, the strong UE of processing capacity can decoding punching refers to before feeding back ACK and/or NACK in the slot Showing information, the weak UE of processing capacity may need that punching instruction information could be decoded after at least one slot duration, if this The ACK and/or NACK of class UE are fed back at the end slot, it is evident that, punching instruction information be in UE feeding back ACK and/or Instruction information decoded cannot be punched before send before NACK but UE feeding back ACK and/or NACK.There are also a kind of feelings Condition, for example, punching occur in slot n, but UE for the data feedback ACK and/or NACK in slot n just timing at this The end of slot n, at this point, if using above-mentioned second, it is clear that minimum can only be sent in next slot of the slot n Punching instruction information, which is also that can not decode punching instruction information before feeding back ACK and/or NACK.

In conjunction with example 2, the threshold value mentioned or ratio in above-mentioned example A and A1 is arranged in base station and UE.Such as pass through Emulation obtains a reasonable ratio K, when the data volume and all data volume ratios of the CB that a CB is perforated are less than or equal to K When, base station and UE think that the CB can be correctly decoded by encoding and decoding gain；When the data volume and the CB that a CB is perforated When all data volume ratios are greater than K, base station and UE think that the CB cannot be correctly decoded by encoding and decoding gain.In this way, one Denier punching occurs, base station can send punching instruction information (mean base station in view of UE processing capacity, enable UE and When decoding punching instruction information before feeding back ACK and/or NACK), base station and UE indicate information according to punching, in conjunction with the TB's The time-frequency domain resources that modulating-coding rule, the mapping ruler of TB and TB are distributed when transmitting, base station and UE can extrapolate the TB In those CB be perforated, and the data volume being struck off in the CB being perforated accounts for the ratio of entire CB, if this ratio is small In being equal to K, base station and UE are considered as the CB and belong to the CB not being perforated；If this ratio is greater than K, base station and UE are considered as this CB belongs to the CB being perforated, and base station and UE can handle the CB according to the processing mode for the CB being perforated in example A.

Obviously, have the setting of ratio K, it is possible to occur: only one CB is perforated in a TB, and the CB is beaten The ratio in hole is less than k, in this way, this CB will be considered the CB not being perforated, and is handled according to the CB not being perforated, UE is such as Fruit correct decoding CB and other CB (TB is also correctly decoded), UE is by feeding back ACK at this time；The UE non-correct decoding CB is still Other all CB (but TB is not correctly decoded) are correctly decoded, UE feeds back NACK at this time.Base station side is also to be somebody's turn to do according in the TB The ratio for the data volume that CB is struck off when determination receives ACK and/or NACK, first determines the formation of the side UE ACK and/or NACK Rule (once determines the specifically used ACK and/or NACK formation rule in the side UE) according to ratio in judgement, then parses ACK again And/or NACK meaning and subsequent retransmission process.If receiving ACK, it is correctly, no that entire TB is thought if in this example all It needs to retransmit again；If receive NACK, then it is assumed that have CB mistake in entire TB, need to retransmit TB.

In conjunction in example 2, actually increase additional Rule of judgment (i.e. a threshold value or ratio on the basis of example A Value judgement first determines the meaning of the ACK and/or NACK of UE feedback according to the condition), exactly consider the journey that a CB is perforated The CB, if the data volume being perforated is bigger, is belonged to the CB being perforated by degree, if the small number being perforated, The CB belongs to the CB not being perforated.Increase ratio condition be mainly the CB of low volume data of being struck off is reduced to be retransmitted because These CB maximum probabilities can pass through encoding and decoding gain correct decoding.

In example A2, if base station has sent punching instruction information, base station is needed according to UE processing capacity and feedback (or slot) determines that the ACK or NACK of UE feedback are specific any situations at the time of ACK and/or NACK: being to eliminate to be beaten Hole CB (when Wen Zhongwei specified otherwise, will consider whether include the punching with threshold value or ratio CB, can in advance about It is fixed), the CB being perforated still is not rejected；UE is also likewise, UE should always be an attempt to receive punching instruction information, and receive It is handled after indicating information to punching according to eliminating the CB being perforated.

In example A2, if punching has occurred, but the not sent punching in base station indicates information, it is clear that UE feeding back ACK And/or NACK always contains the CB being perforated.

Specific embodiment A3

Obviously, in example A2, even if base station has sent punching instruction information, and to UE there are enough decoding times, There is UE decoding punching instruction information failure, for example, punching instruction information will be transmitted through a common set at present in conclusion Downlink Control Information (DCI) is transmitted, and general DCI loading error occurring rate is 1%, in the case where channel quality is bad, Error rate will increase, and such case is also referred to as DCI loss.So being made pair for relying on UE detection punching instruction information When the processing mode answered, occur once DCI loses, base station is by the ACK and/or NACK is corresponding contains that UE is fed back of understanding of mistake Justice, for example, base station has sent punching instruction information but the incorrectly decoded punching of UE indicates information, and UE is not still according to rejecting quilt The CB of punching forms ACK or NACK, and base station thinks that UE is used and forms ACK or NACK according to the CB that rejecting is perforated.At this point, accidentally Solution will necessarily cause additional re-transmission problem.

In order to overcome the above problem, a kind of mode is provided in example A3.

Basic ideas are, in UE feeding back ACK or NACK, notify base station by way of implying or being explicitly indicated, this The ACK or NACK of feedback are (to be denoted as according to the CB (being denoted as situation 1) comprising being perforated also according to the CB being perforated is not included Situation 2).Base station side is also to receive the ACK/NACK information of UE feedback, and when receiving ACK information, base station is according in secret or clear The information of instruction determines that the corresponding affiliated situation of the ACK information is situation 1 or situation 2.Then, it is determined that the data retransmitted retransmit To UE.If ACK corresponding is situation 1, it is correct that base station thinks that the TB is decoded by UE, does not need to retransmit；It is if ACK is corresponding Situation 2, base station think that the TB needs to retransmit the CB being perforated to UE.Here the CB being perforated is divided to for two kinds of situation definition, base It stands and UE needs prior stipulative definition.As long as the first is that CB is punched, the CB being as perforated；Second is that CB is perforated Data are more than threshold value, the CB being as perforated.

In general, due to regardless of being perforated according to the NACK that is formed comprising the CB mode being perforated also according to not including The NACK that CB mode is formed is identical in the processing of base station side, so in order to reduce expense, can not area in two kinds of situation Under NACK.

The specific method for implying or being explicitly indicated includes multiple choices:

Selection 1, base station and UE are about set to formation feeding back ACK or NACK under different situations and distribute different resources.Different Resource includes different sequence, different code words, at least one dimension resource is different in different three dimensions of running time-frequency resource, only There is a dimension difference that can distinguish.When UE forms ACK or NACK according to the different situations that base station configures, with regard to use pair The resource transmission answered is to base station；Base station receives the ACK or NACK of UE feedback in corresponding resource, determines UE according to testing result Form the mode of ACK or NACK.Since UE feeding back ACK is bigger for subsequent re-transmission influence to base station, so in selection 1 Different resources can be only distributed just for ACK.For example, two kinds of situations distribute different sequences, provide in identical time-frequency Source, identical code word (if supporting code word).

For example, base station configuration UE or base station and UE arrange, in situation 1, UE forms feeding back ACK and uses sequence 1, in situation When 2, UE forms feeding back ACK and uses sequence 2.Situation 1 and 2 uses identical time-frequency domain resources, it is assumed that do not support code source. In this way, base station detects that sequence 1 thinks that the ACK of feedback corresponds to situation 1 according to agreement, if detecting that sequence 2 thinks feedback ACK corresponds to situation 2.If ACK corresponding is situation 1, it is correct that base station thinks that the TB is decoded by UE, does not need to retransmit；If ACK Corresponding is situation 2, and base station thinks that the TB needs to retransmit the CB being perforated to UE.

Selection 2, base station and UE agreement when UE sends ACK or NACK, while sending instruction ACK or NACK generation type Bit and/or sequence.For example, UE increases a bit simultaneously in UE feeding back ACK or NACK, this increased bit is used Come describe UE formed ACK or NACK when whether include the CB (being situation 1 or situation 2) being perforated.

In order to reduce the complexity of base station and UE processing, if base station and UE default UE are scheduled, work is allowing to punch biography When in defeated subband or base station is when the TB of UE transmission is punched or base station configuration UE is monitored when punching instruction information, or with When the combination of upper multiple conditions, UE feeding back ACK or NACK always carry 1 bit information.One bit can also use sequence It indicates.For example, original ACK or NACK is a sequence, when UE sends the sequence of ACK/NACK at this time, while additional transmission is another again The case where when one sequence indicates to be formed ACK and/or NACK.Alternatively, base station configuration UE formed feedback ACK or NACK when whether Include the CB being perforated.That is base station is by signaling UE, when above-mentioned condition occurs, UE formed ACK/NACK when whether include The CB being perforated, i.e., whether according to situation 1 or the formation of situation 2 ACK/NACK.

In embodiment above based on example A, A1, A2 and A3, mode in each example in the absence of conflict may be used To be applied in combination.

Specific embodiment A4

Table 1 is the various HARQ-ACK situation summary sheets of A4 according to specific embodiment, as shown in Table 1, when punching refers to Showing information not is when always being sent, i.e., base station optionally sends punching instruction information, then table 1 gives containing for various HARQ-ACK Justice.

Table 1: various HARQ-ACK situations are summarised

Explanation 1 in above table: UE is configured for monitoring punching instruction information here, but after UE may receive it Decoding failure, or miss reception or without time enough decoding punching instruction information before feeding back HARQ-ACK.

Illustrate 2: "Yes" indicates CB by serious punching (such as more than above-mentioned threshold value), which cannot correctly be solved Code；"No" indicates that CB is slightly punched (such as being less than above-mentioned threshold value) or CB is not perforated, which can be correctly decoded.

Whether there is the CB being seriously perforated for the TB of a UE, base station can be known, because punching is exactly base station It executes.Base station and UE can send ACK/NACK according to the situation in table, and base station is according to whether have sent punching instruction Whether whether information, UE are configured to monitor punching instruction information, have serious punching CB to determine that the ACK of UE feedback is ACK1 on earth Or ACK2.For example, if base station has sent punching instruction information, configuration UE monitors punching instruction letter when UE has fed back ACK Breath, and be slight (the above-mentioned threshold value for being less than setting) for the CB being perforated in the TB of the UE, base station is thought at this time ACK is ACK2.For example, when UE has fed back ACK, if the not sent punching in base station indicates information, and for being beaten in the TB of the UE The CB in hole be it is slight, base station thinks that ACK at this time is ACK2.Such as when UE has fed back ACK, if base station has sent punching and refers to Show information, configuration UE monitors punching instruction information, and is serious (upper more than setting for the CB being perforated in the TB of the UE State threshold value), base station thinks that ACK at this time is ACK1.For example, if UE has fed back ACK, base station has sent punching instruction information, But monitoring punching instruction information is not configured in UE, then the ACK of UE feedback is ACK2.In above-mentioned example in Rule of judgment, to the UE TB in the CB that is perforated be it is serious or it is slight can also be not as Rule of judgment.

In addition, if after punching instruction generation, base station always sends punching instruction information, then in table 1 just only Scene 1~4.In this case, base station is according to whether configuration UE monitors punching instruction information, if has serious punching CB true The ACK for determining UE feedback is ACK1 or ACK2 on earth.For example, referring to when UE has fed back ACK if being configured for the UE and monitoring punching The CB for showing information, and being perforated in TB is slight (the above-mentioned threshold value for being less than setting), and base station thinks that ACK at this time is ACK2.Such as when UE has fed back ACK, if configuring monitoring punching instruction information for the UE, and the CB being perforated in TB is tight (more than the above-mentioned threshold value of setting) of weight, base station thinks that ACK at this time is ACK1.Such as when UE has fed back ACK, if for Monitoring punching instruction information is not configured in the UE, then the ACK of UE feedback is ACK2.In above-mentioned example in Rule of judgment, to the UE TB in the CB that is perforated be it is serious or it is slight can also be not as Rule of judgment.

Herein, be equivalent to according to the condition of agreement and judge the affiliated situation of ACK, do not need additional signaling indirectly or It directly is sent to base station, to indicate the affiliated situation of ACK.But this method is built upon on the basis of a hypothesis establishment , that is, when thinking punching, if the data that CB is perforated are more, more than above-mentioned threshold value, then the CB is unable to correct decoding, no Then, can be with correct decoding, this assumes that it will lead to the method existing defects of above-mentioned A4 there are certain probability is invalid.But It is if it is considered that do not increase signaling, in this way and a kind of method.

Specific embodiment A5

In the present example, situation be used to indicate base station to terminal send transport block data during there is a phenomenon where fields Scape, or referred to as background；The information A (information A is identified as ACK in other embodiments) that situation is used to indicate terminal feedback refers to Situation belonging to the decoding terminals shown, for example whether being successfully decoded to comprising the entire transmission block including the CB that is perforated.But this In examples of implementation, if information A is identified as NACK, situation belonging to corresponding information A instruction terminal decoding, for example, feedback After NACK, situation A (here in order to which distinctive information A is identified as ACK, being denoted as situation A here) is that UE is properly received punching instruction letter After breath, UE at least one CB data decoding errors in the CB not being perforated in received transport block data (no matter be perforated Whether CB is correctly decoded), transmission block decoding error；Alternatively, it (includes that UE decoding is wrong that UE is not properly received punching instruction information here Accidentally, miss reception and do not receive punching instruction information), transmission block decoding error；Situation B is (here in order to which distinctive information A is identified as ACK is denoted as situation B here) be, UE to all CB data in received transport block data in addition to the CB being perforated at Function decoding, the CB being perforated are decoded not successfully, transmission block (CRC check does not pass through) decoding error.Under situation A, base station is retransmitted Entire TB.Under situation B, base station retransmits the CB (saving the CB for retransmitting and not being perforated) being perforated.When information A is identified as NACK, it Shared information A is identified as the situation (5 kinds of situations) when ACK.Its shared information A is identified as situation A belonging to the differentiation used when ACK Or the method for situation B.The case where not conflicting, it can be shared or all methods when combining information A is identified as ACK.Some examples Son is shown in specific embodiment A5.

Sub- A3 is for some examples in conjunction with specific embodiments.

Basic ideas are, when UE feeds back NACK, notify base station by way of implying or being explicitly indicated, this feedback NACK is to be formed according to situation A or situation B is formed.Base station side is also the nack message for receiving UE feedback, when receiving Nack message, base station determine that the corresponding affiliated situation of the nack message is situation A or feelings according to the information for implying or being explicitly indicated Condition B.Then, it is determined that the data retransmitted are retransmitted to UE.If NACK corresponding is situation A, base station retransmits the TB；If NACK pairs That answer is situation B, and base station thinks that the TB needs to retransmit the CB being perforated to UE.Here the CB being perforated is divided to be determined for two kinds of situations Justice, base station and UE need prior stipulative definition.As long as the first is that CB is punched, the CB being as perforated；Second is CB The data that are perforated are more than threshold value (be specifically defined and see previous embodiment), the CB being as perforated.

For example, base station configuration UE or base station and UE arrange, in situation A, UE forms feedback NACK and uses sequence 1, in feelings When condition B, UE forms feedback NACK and uses sequence 2.Situation A and B, use identical time-frequency domain resources, it is assumed that do not support code word to provide Source.In this way, base station detects that sequence 1 thinks that the NACK of feedback corresponds to situation A according to agreement, if detecting that sequence 2 thinks anti- The NACK of feedback corresponds to situation B.If NACK corresponding is situation A, it is correct that base station thinks that the TB is not decoded by UE, needs to retransmit TB；If NACK corresponding is situation 2, base station thinks that the TB needs to retransmit the CB being perforated to UE.

Selection 2, base station and UE agreement when UE sends ACK or NACK, while sending instruction ACK when said circumstances occur Or the bit and/or sequence of NACK generation type.For example, UE increases a bit simultaneously in UE feeding back ACK or NACK, this Increased bit bit value be used to describe UE formed ACK or NACK when whether include be perforated CB (be situation A also It is situation B).

In order to reduce the complexity of base station and UE processing, if base station and UE default UE are scheduled, work is allowing to punch biography When in defeated subband or base station is when the TB of UE transmission is punched or base station configuration UE is monitored when punching instruction information, or with When the combination of upper multiple conditions, UE feeding back ACK or NACK always carry 1 bit information.One bit can also use sequence It indicates.For example, original ACK or NACK is a sequence, when UE sends the sequence of ACK/NACK at this time, while additional transmission is another again The case where when one sequence indicates to be formed ACK and/or NACK.Alternatively, base station configuration UE formed feedback ACK or NACK when whether Include the CB being perforated.That is base station is by signaling UE, when above-mentioned condition occurs, UE formed ACK/NACK when whether include The CB being perforated, i.e., whether according to situation A or situation B formation ACK/NACK.

For above-mentioned several specific embodiments, need to make following explanation:

In the application, situation affiliated for ACK is divided into 2 kinds and is described, and the UE in the application is to the transmission Block number all CB data in addition to the CB being perforated in are successfully decoded, and the UE can also send NACK to base station, NACK meaning at this time is denoted as above-mentioned: UE to all CB data in the transport block data in addition to the CB being perforated at Function decoding.NACK at this time, can be denoted as NACK1, essence be it is different with NACK that is being formed in the case of other (for example, UE not by The NACK formed when also having the CB not being correctly decoded in the CB of punching).So, that is to say, that in above-mentioned UE to the transmission When all CB data of the block number in addition to the CB being perforated are successfully decoded, UE feeding back ACK or NACK, as long as at this time The implication that ACK or NACK is indicated is UE to all CB data in the transport block data in addition to the CB being perforated It is successfully decoded.But it to distinguish and the ACK or NACK that are formed in the case of other.

That is, the application essence is to discriminate between two kinds of above-mentioned situations, regardless of second situation, (UE is to the transmission block All CB data in data in addition to the CB being perforated are successfully decoded) it (can also labeled as ACK with what identifier With being labeled as NACK can also be to illustrate for labeled as ACK herein as long as appointing in advance) description, essence is to want Area is in two kinds of situation: all CB data in the transport block data in addition to the CB being perforated are successfully decoded UE and institute UE is stated to be successfully decoded in the transport block data comprising all CB data including the code block CB that is perforated.

Specific embodiment B

The behavior of base station and UE:

Base station is before UE feeds back the HARQ-ACK of the TB, and base station to UE sends punching instruction information, and (or base station and UE are about When making now five kinds of situations above-mentioned).Wherein punching indicates that information describes those resources in the slot and is perforated, such as passes through OFDM symbol and frequency domain information describe.UE punches instruction information based on the received, and the modulating-coding in conjunction with the TB is regular, TB The time-frequency domain resources that mapping ruler and TB are distributed when transmitting, UE can extrapolate those CB in the TB and be perforated.Base station Those specific CB in the TB that each UE is perforated at punching can be equally extrapolated to be perforated.

Base station and UE agreement, if having CB to be perforated in a TB, when UE feeds back ACK and/or NACK of the TB, are pressed According to ACK and/or the NACK feedback of CBG rank.CBG format is by configured in advance to UE.The division of CB to CBG in TB can refer to The prior art.

Base station and UE are fed back according to the ACK and/or NACK of CBG rank, determine corresponding retransmission process (such as with reference to this case Before the applying date, in the related technology based on the retransmission mechanism of CBG).

Likewise, can also introduce threshold value or ratio in above-mentioned example, definition and usage are similar in example A2. When the ratio that CB is perforated is less than or equal to threshold value or ratio, base station and UE think that the CB belongs to the CB not being perforated.If CB When the ratio being perforated is greater than threshold value or ratio, base station and UE think that the CB belongs to the CB being perforated.Increase threshold value or Processing after ratio is with reference to the description in example A2.

When base station retransmits data, base station is able to use Downlink Control Information (DCI) format identical with initial transmission, so as to DCI is detected in UE；Alternatively, other DCI formats (such as DCI format with CBG instruction) also can be used in base station, but it is described Other DCI formats are to have been arranged, it is reused after capable of being triggered by above-mentioned event by base station, i.e., above-mentioned feedback retransmits hair Base station default is using other described DCI formats when raw, and such UE is convenient for detection DCI.

CBG mechanism also can be applied to CB rank, and specific processing is identical.It is considered that the operation of CBG and the behaviour of CB Be as essence it is identical, can be interchanged, only the difference of the corresponding granularity of CB and CBG.

In this example, occur (to be also possible to base station as trigger condition and UE agreement occurs above-mentioned five by punching event Kind situation is as trigger condition), the HARQ-ACK feedback mechanism of automatic trigger CBG rank when punching generation, although increasing The expense of UE feedback information, but re-transmission data volume can be reduced, such as the CBG or CB of correct decoding will not be retransmitted, especially It is not to be properly decoded CB (or CBG) if had in the CBs (or CBGs) not being perforated, in this example, then can only retransmit This kind of CB (or CBG).Such as in example A, UE has fed back NACK, and base station retransmits entire TB；And in this example, due to feedback be by It is executed according to the HARQ-ACK of CBG rank, so can recognize that those CB (or CBG) are not correctly decoded in TB, so can Only to retransmit the CB not being correctly decoded (or CBG).

Specific embodiment C

The behavior of base station and UE:

Before UE feeds back the HARQ-ACK of the TB, base station is that UE retransmits the CB (or CBG) being perforated, and uses band for base station The DCI format (it can indicate that that CB in TB or CBG are transmitted) for having CB (or CBG) to indicate, transmits phase using with TB Same process number.Base station and UE think that this re-transmission is the re-transmission for punctured data.UE receives the data retransmitted, and according to CB (CBG) it indicates, with the data of the received position that is perforated before received re-transmission data replacement.Then it is translated for TB Code, and feed back the HARQ-ACK of TB rank or CBG rank.

Or；

Base station is before UE feeds back the HARQ-ACK of the TB, and after base station sends punching instruction information, base station is that UE retransmits quilt The CB (or CBG) of punching, and use with just pass identical DCI format, use process number identical when transmitting with TB.Base station and UE Think that this re-transmission is the re-transmission for punctured data.UE receives the data retransmitted, and is beaten according to punching instruction information reckoning The CB (CBG) in hole, with the data of the received position that is perforated before received re-transmission data replacement.Then it is translated for TB Code, and feed back the HARQ-ACK of TB rank or CBG rank.

Specific embodiment D

If UE has fed back NACK, when base station retransmits TB, the behavior of base station and UE:

Base station and UE agreement, if base station retransmits TB, base station uses the DCI format with CBG instruction.It thus can be with Using based on CBG feedback and retransmission mechanism in the feedback for retransmitting and retransmitting.Here NACK is mainly fed back by punching+UE It as condition, triggers base station and is retransmitted when retransmitting TB using the DCI format indicated comprising CBG, in order to which UE executes DCI inspection It surveys.

Later, UE when feedback () twice and more than twice when for current retransmission feedback HARQ-ACK, can be by According to TB rank or CBG rank.

Specific embodiment E

UE is configured to carry out HARQ-ACK feedback based on TB.Data are transmitted, if UE has fed back TB rank NACK, when base station retransmits TB, the behavior of base station and UE:

Base station and UE agreement, if base station retransmits TB, base station uses the DCI format with CBG instruction.It thus can be with Using based on CBG feedback and retransmission mechanism in the feedback for retransmitting and retransmitting.Here TB rank has mainly been fed back by UE NACK as condition, trigger base station and retransmitted when retransmitting TB using the DCI format indicated comprising CBG, in order to which UE is held Row DCI detection.

UE when feedback () twice and more than twice when for current retransmission feedback HARQ-ACK, can be according to TB grades It is other or CBG rank.

Through the above description of the embodiments, those skilled in the art can be understood that according to above-mentioned implementation The method of example can be realized by means of software and necessary general hardware platform, naturally it is also possible to by hardware, but it is very much In the case of the former be more preferably embodiment.Based on this understanding, technical solution of the present invention is substantially in other words to existing The part that technology contributes can be embodied in the form of software products, which is stored in a storage In medium (such as ROM and/or RAM, magnetic disk, CD), including some instructions are used so that terminal device (it can be mobile phone, Computer, server or network equipment etc.) execute method described in each embodiment of the present invention.
