Description

Utilize the method for hole knockout transmission answer signal

Technical field

The present invention relates to the link adaptation techniques in the wireless communication system, be specifically related to the transmission and the method for reseptance of answer signal in automatic re-send request may technology.

Background technology

Third generation partner plan (being called for short 3GPP) is a technology standardization tissue of implementing 3-G (Generation Three mobile communication system), and wherein the 3G (Third Generation) Moblie technical standard comprises Frequency Division Duplexing (FDD) (FDD) and time division duplex (TDD) pattern technology standard.3GPP has announced Release 99, Release4, the version of Release 5 these three 3-G (Generation Three mobile communication system) technical standards from setting up so far.Wherein, the Release99 version was announced in October, 1999, mainly comprised the Frequency Division Duplexing (FDD) (FDD) of 3.84Mcps and the 3-G (Generation Three mobile communication system) technical standard of time division duplex (TDD); Release 4 versions announced in 2000, mainly comprised the 3-G (Generation Three mobile communication system) technical standard of the time division duplex (TDD) of the Frequency Division Duplexing (FDD) (FDD) of 3.84Mcps and time division duplex (TDD) and 1.28Mcps; Release 5 announces that in calendar year 2001 this version is to have added high-speed data packets access (HSDPA) function on the basis of Release 4 versions.At present, 3GPP is implementing the 3-G (Generation Three mobile communication system) up link technique for enhancing beforehand research of the time division duplex (TDD) of the Frequency Division Duplexing (FDD) (FDB) of 3.84Mcps and time division duplex (TDD) and 1.28Mcps, and expection will be in formal research up link technique for enhancing standardization effort on to the basis of above-mentioned up link technique for enhancing beforehand research in 2004, and the technical scheme that is produced will be contained in 3-G (Generation Three mobile communication system) technical standard Release 6 versions of time division duplex (TDD) of the Frequency Division Duplexing (FDD) (FDD) of following 3.84Mcps and time division duplex (TDB) and 1.28Mcps.

No matter for the up enhancement techniques of the Frequency Division Duplexing (FDD) (FDD) of 3.84Mcps spreading rate in the 3-G (Generation Three mobile communication system) and time division duplex (TDD), still for the up link enhancement techniques of the time division duplex (TDD) of 1.28Mcps spreading rate, the purpose that up channel strengthens is: uplink transmission resource is effectively managed and plan by wireless network, the up-link capacity of raising system, and make it to be suitable for the stronger data service of transmitting burst.For frequency division duplex system, by up enhancement techniques, improve the performance of uplink dedicated transmission channel, improve the coverage rate and the throughput of sub-district, improve uplink speed, reduce uplink delay.For tdd systems, by up enhancement techniques, improve the performance of uplink dedicated transmission channel and up Common transport channel, improve the coverage rate and the throughput of sub-district, improve uplink speed, reduce uplink delay.The up enhancement techniques of research mainly comprises mixed automatic retransmission request technology, dispatching technique etc. at present.

Mixed automatic repeat request (being called for short HARQ down) is one of key technology during up channel strengthens.The HARQ method is that the automatic repeating transmission of packet and chnnel coding are combined a kind of method of carrying out transfer of data.In using the system of mixed automatic repeat request, receiving terminal can return to answer signal of transmitting terminal after receiving the packet of transmitting terminal.Whether this answer signal is used to indicate data packets for transmission correctly to be received.If the packet that sends is correctly received, the answer signal of receiving terminal feedback is affirmative acknowledgement signal (being designated hereinafter simply as ACK).If the packet that sends is not correctly received, the answer signal of receiving terminal feedback is negative acknowledgement (being designated hereinafter simply as NACK).If transmitting terminal receives the NACK signal, transmitting terminal can resend same packet or its relevant information usually; If transmitting terminal receives ack signal, the transmission course that transmitting terminal can an initial new data packets.Can know that based on above analysis the proper operation that is transmitted as HARQ of ACK/NACK answer signal plays an important role.How regulation does not transmit descending ACK/NACK answer signal in existing 3GPP specification version.Therefore how to transmit in the up enhancing research project ack/nack signal relevant and be present 3GPP physical layer working group a focus direction of studying is discussed with HARQ.The more existing at present companies of problem have proposed some possible schemes hereto.Such as, in the 3GPP meeting, Samsung proposes to transmit descending ack/nack signal by Dedicated Physical Data Channel is punched.In this method, original some transmitted bit of physical channel is struck off according to predetermined drilling method, and at corresponding bit position transmission answer signal.

But the scheme that has proposed at present is aimed at the proposition of Frequency Division Duplexing (FDD) (being designated hereinafter simply as FDD) system, can not be used for time division duplex (being designated hereinafter simply as TDD) system.This mainly is because up link allows that the number of simultaneous up coded combination transmission channel (being designated hereinafter simply as CCTrCH) is different in TDD system and the FDD system.In the FDD system, up link is only allowed coded combination transmission channel of existence.Yet in the TDD system, up link is allowed existence one or more coded combination transmission channel.

In the 3GPP standard, the coded combination transmission channel has two types, promptly comprises the CCTrCH of private type and the CCTrCH of public type.One or more transmission channels can constitute a coded combination transmission channel by code multiplexing.The CCTrCH of private type is meant that one or more dedicated channels (DCH) are by coded combination transmission channel of code multiplexing processing composition.The CCTrCH of public type is meant that one or more common channels (DCH) are by coded combination transmission channel of code multiplexing processing composition.A broadcast channel can constitute a coded combination transmission channel by coding.Random Access Channel or forward access channel can constitute a coded combination transmission channel by coding.One or more Uplink Shared Channels or DSCH Downlink Shared Channel also can constitute a coded combination transmission channel by coding.

In the Frequency Division Duplexing (FDD) code division multiple access system, up link is only allowed coded combination transmission channel of existence.Introduced after the HARQ technology, down link is only with the answer signal that provides a correspondence.Therefore, the scheme that is directed to the proposition of FDD system only considers how to transmit a descending ack/nack signal, does not need to consider and do not have to consider how to transmit the mapping relations of a plurality of ack/nack signals and a plurality of ack/nack signal and many up coded combination transmission channels at present.

In TDD-CDMA system, the up link of a user terminal UE can be allowed and had one or more coded combination transmission channel CCTrCH simultaneously.The CCTrCH that many CCTrCH can be a plurality of private types is merged into, and also can be that the CCTrCH of a plurality of public types is merged into, and can be the CCTrCH of private type and form common merging of CCTrCH of public type.A CCTrCH can be mapped on one or several physical channel.If a up CCTrCH is mapped on a plurality of physical channels, the spreading factor of these physical channels can be different so.

If the TDD system has introduced up enhancing HARQ technology, up link just has many CCTrCH that support the HARQ technology so, so down link must provide the pairing ACK/NACK answer signal of these coded combination transmission channels respectively.Thus, the possibility that just has a plurality of ACK/NACK of transmission in the down link.Therefore, in the TDD system, need to consider how to transmit a plurality of ack/nack signals.The present invention proposes to utilize the mode that down physical channel is punched to transmit a plurality of descending ack/nack signals.

In the TDD-CDMA system (being designated hereinafter simply as LCR-TDD) of low spreading rate (1.28Mcps), the Transmission Time Interval of a CCTrCH can be 5 milliseconds, 10 milliseconds, and 20 milliseconds, 40 milliseconds and 80 milliseconds.In present R99 specification version, having only the Transmission Time Interval of the CCTrCH of Random Access Channel formation can be 5 milliseconds.But introduce after the HARQ technology,, support the Transmission Time Interval of the up CCTrCH of HARQ also may be 5 milliseconds in order to reduce uplink delay.That is to say that support the HARQ technology and the up CCTrCH's that is made of dedicated channel Transmission Time Interval may be 5 milliseconds.In addition, support the Transmission Time Interval HARQ technology and up CCTrCH that constitute by Uplink Shared Channel also may be 5 milliseconds.But since at present the Release6 specification version still under study for action, the Transmission Time Interval of supporting the up CCTrCH of HARQ may be 5 milliseconds or 10 milliseconds are not determined.

In the TDD-CDMA system of low spreading rate (1.28Mcps), the length of a radio frames is 10 milliseconds.The LCT-TDD system is in order to realize fast power control and timing advance calibration and some new technologies to be supported that one 10 milliseconds radio frames are divided into two structures finish identical subframe, the duration of each subframe is 5ms.The frame of system and the hierarchical chart of subframe are as shown in Figure 1.If support that the Transmission Time Interval of the up CCTrCH of HARQ is 5 milliseconds, i.e. sub-frame length, this up CCTrCH finishes transmission by physical channel mapping meeting in a subframe so.If support that the Transmission Time Interval of the up CCTrCH of HARQ is 10 milliseconds, i.e. wireless frame length, this up CCTrCH finishes transmission by physical channel mapping meeting in two subframes so, promptly finishes transmission in a radio frames.

In the TDD-CDMA system (being designated hereinafter simply as HCR-TDD) of high spreading rate (3.84Mcps), the Transmission Time Interval of a CCTrCH can be 10 milliseconds, 20 milliseconds, and 40 milliseconds and 80 milliseconds.But introduce after the HARQ technology,, support that the Transmission Time Interval of the up CCTrCH of HARQ should be 10 milliseconds in order to reduce uplink delay.Be that up CCTrCH finishes transmission by physical channel mapping meeting under 10 milliseconds the situation in a radio frames at this Transmission Time Interval.

In addition, in the TDD system, how to determine that the relation between a plurality of answer signals and a plurality of up CCTrCH also needs to study.Node B can adopt the mapping relations of mode informing user terminal between the two of dominance.The mode of dominance means also needs the CCTrCH that indicates with this signal correction to number in each ACK/NACK answer signal of transmission.That is to say that each ACK/NACK answer signal must transmit jointly with relevant up CCTrCH numbering.Adopt this mode, signaling consumption is very big.Can know from above analysis, in the TDD system, introduced after the HARQ enhancement techniques, not only to consider how to transmit a plurality of ack/nack signals, and must consider the mapping relations between a plurality of ack/nack signals and many up coded combination transmission channels.

Summary of the invention

The purpose of this invention is to provide a kind of mode that down physical channel is punched of in TDD-CDMA system, utilizing and transmit the method for answer signal ACK/NACK.

Another object of the present invention provides a kind of method of determining descending answer signal and up coded combination transmission channel mapping relations in TDD-CDMA system.

Embodiment

In TDD-CDMA system, can there be one or more coded combination transmission channel CCTrCH simultaneously in the up link of a UE.If these many coded combination transmission channel CCTrCH have introduced the HARQ technology, down link need feed back the pairing ACK/NACK answer signal of these CCTrCH so.This has shown that down link need consider to transmit a plurality of ACK/NACK answer signals.

In order to transmit a plurality of answer signals, the present invention proposes and a kind ofly in TDD-CDMA system, transmit the method for descending ack/nack signal by down physical channel is punched.Among the present invention, punching means that original some transmitted bit of physical channel is struck off, and these transmitted bits of being struck off no longer are transmitted, and at corresponding bit position transmission answer signal.

In the present invention, Node B receives after the upstream data of transmission in some transmission time unit, will be to each supports the up CCTrCH of HARQ technology to produce an ACK/NACK answer signal respectively in this transmission time unit, determine which transmission time unit to transmit these answer signals according to the transmit timing of the answer signal of predesignating then in, and determine which physical channel is used to transmit these answer signals, then selected physical channel is carried out punch operation with the transmission answer signal.

Among the present invention, Node B utilizes the method that hole knockout transmits descending ack/nack signal can realize that the realization block diagram of this process as shown in Figure 2 by following basic step.The performing step of this process can be described below:

Step 201, which transmission time unit transmission answer signal Node B determines at according to the transmit timing of descending answer signal.

Step 202, Node B determines to use which or which down channel sign indicating number to transmit descending answer signal.

Step 203, Node B carries out punch operation respectively to transmit descending ack/nack signal according to predefined drilling method to selected down channel sign indicating number.

Step 204, Node B is numbered the up CCTrCH that needs in the transmission time unit that is considered to feed back answer signal.

Step 205, the punch position that Node B puts into appointment according to predefined answer signal transmission plan successively with the pairing ack/nack signal of up CCTrCH transmits.

Above step is at a designated user terminal.In above step, step 204 can any one step before step 205 be carried out.If a plurality of user terminals are arranged, can as above operate respectively to transmit each self-corresponding answer signal at each user terminal.

If support that the Transmission Time Interval of the up CCTrCH of HARQ is 5 milliseconds, Node B is a processing unit with a subframe in above step so, and the transmission time unit among the present invention is a subframe.If support that the Transmission Time Interval of the up CCTrCH of HARQ is 10 milliseconds, Node B is a processing unit with a radio frames in above step so, and the transmission time unit among the present invention is a radio frames.

In step 201 of the present invention, the transmission of ACK/NACK answer signal should be satisfied predefined transmit timing.For the transmit timing of step 201, the present invention proposes transmission time of descending ACK/NACK answer signal and should be at least falls behind a transmission time unit than up CCTrCH transmission time of answer signal correspondence.That is to say that if up CCTrCH finishes transmission in k transmission time unit, answer signal should transmit so in (k+n) individual transmission time unit.Parameter n represents time difference of weighing with the transmission time unit between transmission time of the transmission time of up CCTrCH and answer signal.Wherein parameter n should be more than or equal to 2.

If support that the Transmission Time Interval of the up CCTrCH of HARQ is 5 milliseconds, the transmission of so up CCTrCH only takies a transmission subframe.If up CCTrCH finishes transmission in k subframe, answer signal should transmit in (k+n) individual subframe so.Wherein parameter n represents that the subframe sequence number of transmitting between up CCTrCH and the transmission answer signal is poor.If support that the Transmission Time Interval of the up CCTrCH of HARQ is 5 milliseconds, parameter n must be more than or equal to 2.

If support that the Transmission Time Interval of the up CCTrCH of HARQ is 10 milliseconds, the transmission of so up CCTrCH takies two transmission subframes, promptly takies a radio frames.If up CCTrCH finishes transmission in k radio frames, answer signal should transmit in (k+n) individual radio frames so.Wherein parameter n represents that the Radio Frame Number that transmits between up CCTrCH and the transmission answer signal is poor, and parameter n must be more than or equal to 2.

In step 201 of the present invention, transmission simultaneously, the principle of replying are simultaneously satisfied in the transmission of ACK/NACK answer signal.This principle shows that for designated user the answer signal of finishing all up CCTrCH of transmission in the same Transmission Time Interval should transmit simultaneously in another Transmission Time Interval.

Being 5 milliseconds with the Transmission Time Interval of the up CCTrCH that supports HARQ is example, in the present invention, if the designated user terminal is assigned with the up coded combination transmission channel of a plurality of introducing HARQ technology in same subframe, the pairing ACK/NACK answer signal of these CCTrCH should send in same subframe simultaneously so, and the transmission time of these ACK/NACK answer signals should fall behind a subframe in time at least than the subframe at HARQ process place.

Being 5 milliseconds with the Transmission Time Interval of the up CCTrCH that supports HARQ is example, and in k subframe, the designated user terminal is assigned with N _ULIndividual up coded combination transmission channel is in order to the transmit ascending data bag, and these up CCTrCH support the HARQ technology, and Node B receives and can be respectively these CCTrCH behind these CCTrCH and produced corresponding answer signal so.These answer signals should transmit in the some subframes after k subframe, such as transmission in (k+2) individual subframe or subframe thereafter.This that is to say, transmits and need the upstream data bag of feedback answer signal for all in k subframe, and Node B will select (k+2) individual subframe or certain subframe thereafter comes to transmit corresponding answer signal for it in step 201 so.

It is under 5 milliseconds the condition that Fig. 4 has provided Transmission Time Interval at the up CCTrCH that supports HARQ, a schematic diagram of ACK/NACK answer signal and the transmit timing relation of the up CCTrCH that supports the HARQ technology.In this schematic diagram, specify UE two up CCTrCH that support the HARQ technology to be arranged k subframe, these two pairing ack/nack signals of up CCTrCH will be transferred in (k+2) individual subframe specifies UE.

Being 10 milliseconds with the Transmission Time Interval of the up CCTrCH that supports HARQ is example, in the present invention, if the designated user terminal is assigned with the up coded combination transmission channel of a plurality of introducing HARQ technology in same radio frames, the pairing ACK/NACK answer signal of these CCTrCH should send in another radio frames simultaneously so, and the transmission time of these ACK/NACK answer signals should fall behind a radio frames in time at least than the radio frames at HARQ process place.

In step 202 of the present invention, the down channel sign indicating number that transmits descending ack/nack signal is unfixing.That is to say that for the user terminal of some appointments, any one channel code that the downlink coding combination of transmitted channel in transmission time unit is shone upon can be used to transmit descending ack/nack signal by the mode of punching.But, Node B will decide which or which down channel sign indicating number to be used for transferring ACK/NACK signal according to the relative size relation and the predefined drilling method of the total number of the up CCTrCH of the total number of available down channel sign indicating number and needs feedback answer signal.

Select in the step 202 of the present invention transferring ACK/NACK signal physical channel implementation procedure as shown in Figure 3.The performing step of this process can be described below:

Step 202-1, Node B is numbered all spendable channel code in the transmission time unit of distributing to this user terminal transmission answer signal selected in step 201.If support that the Transmission Time Interval of the up CCTrCH of HARQ is 5 milliseconds, the transmission time unit that transmits answer signal so should be certain subframe that is determined according to the transmit timing relation.If support that the Transmission Time Interval of the up CCTrCH of HARQ is 10 milliseconds, the transmission time unit that transmits answer signal so should be certain frame that is determined according to the transmit timing relation.

Step 202-2, Node B judges the total number N of channel code available in the transmission time unit of selected transmission answer signal _DLTotal number N with the up CCTrCH that in the transmission time unit that is considered, needs to feed back answer signal _ULMagnitude relationship between the two.If the former is less than the latter, execution in step 202-3 then; Otherwise execution in step 202-4.If support that the Transmission Time Interval of the up CCTrCH of HARQ is 5 milliseconds, the transmission time unit that is considered so should be certain subframe that is considered.If support that the Transmission Time Interval of the up CCTrCH of HARQ is 10 milliseconds, the transmission time unit that is considered so should be considered certain radio frames.

Step 202-3, if in the transmission time unit of selected transmission answer signal the total number N of available channel code _DLLess than the total number of the up CCTrCH that needs to feed back answer signal in the transmission time unit that is considered, the Node B decision whole down channel sign indicating numbers that will distribute to this UE all must be used for transferring ACK/NACK answer signal so.

Step 202-4, if in the transmission time unit of selected transmission answer signal the total number N of available channel code _DLBe not less than the total number N of the up CCTrCH that needs the feedback answer signal _UL, the less preceding N of numbering will be only adopted in Node B decision so _ULIndividual down channel sign indicating number comes transferring ACK/NACK answer signal.

Above step is at a designated user.If a plurality of users are arranged, can carry out aforesaid selection step respectively at each user terminal.

For the parameter N that relates in the down channel sign indicating number selection course _UL, Node B and UE can know by high-level signaling separately.For the parameter N that relates in the physical channel selection course _DL; NodeB and UE separately can be earlier know the number of the channel code that total number and each descending CCTrCH shone upon of the descending CCTrCH that distributes to UE in the transmission time unit of selected transmission answer signal by high-level signaling, and the number by channel code that these descending CCTrCH are shone upon separately carries out the total number N that read group total is known channel code available in the transmission time unit of selected transmission answer signal then _DL

In step of the present invention (202-1), need all available down channel sign indicating numbers in the transmission time unit of selected transmission answer signal are numbered.The numbering mechanism of the down channel sign indicating number that the present invention proposes can be described below:

(1) in same transmission time unit, all down channel sign indicating numbers of distributing to the designated user terminal all must be numbered.

(2) numbering of the pairing down channel sign indicating number of the spreading code that the spread spectrum sequence number is little is little.

If the spread spectrum sequence number of the spreading code that the spread spectrum sequence number of the spreading code that certain down channel sign indicating number is distributed is distributed less than another down channel sign indicating number, the numbering of this down channel sign indicating number is just less than the numbering of another down channel sign indicating number so.

(3) numbering of the down channel sign indicating number that transmits earlier is less than the numbering of the down channel sign indicating number that transmits thereafter.

If the transmission time slot that the transmission time slot that some down channel sign indicating numbers are distributed is distributed prior to another down channel sign indicating number on time-domain, the numbering of this down channel sign indicating number is just less than the numbering of another down channel sign indicating number so.

In the present invention, the numbering of down channel sign indicating number can be since 0, but is not limited to since 0.In addition, the spread spectrum sequence number of mentioning spreading code among the present invention can be consistent with scheme that the spread spectrum sequence number of spreading code is numbered in the present existing standard.The scheme that in the at present existing standard spread spectrum sequence number of spreading code is numbered can be referring to the R5 version of the physical layer specification 25.221 of tdd systems.Above numbering process can be finished by the physical layer of system.

In the step 203 of the present invention, the implementation procedure of the punch operation of down channel sign indicating number can be described below: step 203-1, Node B determine the number that each selected down channel sign indicating number need punch.Step 203-2, Node B punches to the down physical channel sign indicating number according to predetermined drilling method and definite punching number.

Required bit number of ack/nack signal of hypothesis expression is N among the present invention _AckIndividual bit.Parameter N wherein _AckCan be for more than or equal to 1 value.This parameter can also can be notified UE by broadcast channel in real time in Node B and UE end predetermined fixed.

Among the present invention, determine that the implementation procedure of down channel sign indicating number punching number can be referring to shown in Figure 5.This process can specifically describe as follows:

Step 203-1-1, Node B judges the total number N of channel code available in the transmission time unit of selected transmission answer signal _DLTotal number N with the up CCTrCH of answer signal to be feedback such as in the transmission time unit that is considered _ULMagnitude relationship, if the former is less than the latter, execution in step 203-1-2 then; Otherwise execution in step 203-1-3.

If step 203-1-2 is N _DLLess than N _UL, Node B is to the punch definite operation of number of all down channel sign indicating numbers so.All the down channel sign indicating number all will transmit descending ack/nack signal by punching, and each down channel sign indicating number will carry one or more ack/nack signals.Suppose that parameter p represents n _ULDivided by N _DLThe value that rounds downwards afterwards, promptly

So for the less preceding (N of numbering _DL-1) individual down channel sign indicating number, each down channel sign indicating number need be destroyed N _AckThe location transmission p of a p bit ack/nack signal; For last down channel sign indicating number, need destroy N _Ack(N _UL-p (N _DL-1)) location transmission of individual bit is transmitted (N _UL-p (N _DL-1)) individual ack/nack signal.

If step 203-1-3 is N _DLBe not less than N _UL, and Node B is only to numbering less preceding N _ULThe punch definite operation of number of individual down channel sign indicating number.For the less preceding N of numbering _ULIndividual down channel sign indicating number, each down channel sign indicating number will transmit descending ack/nack signal by since punching, and each down channel sign indicating number only carries an ack/nack signal.That is to say that the number that each selected down channel sign indicating number need punch is bit number that ack/nack signal is required of expression, the number that promptly punches is N _AckIndividual bit.

Among the present invention, the punching process of down channel sign indicating number is achieved as follows among the step 203-2: the punching number according to determining in predetermined drilling method and the preceding step, carry out punch operation respectively to each channel code.

Among the present invention, hole knockout can for hole knockout at random so that guarantee the randomness of each punch position as far as possible.The drilling method at random that the present invention proposes can be described below: the position P that is numbered (i+1) individual punching bit of j down channel sign indicating number _{I, j}Can determine according to following formula: P _{I, j}=(P _SYS* cnst+j+i) mod (N _{Data, j}), i=0, Λ, (M _{Ack, j}-1), j=0, Λ, (N _DL-1) P wherein _{I, j}Expression is numbered the position of (i+1) individual punching bit of j down channel sign indicating number, N _{Data, j}Expression is numbered the bit number of the data division of j down channel sign indicating number, parameter M _{Ack, j}Expression is numbered the bit number that the down channel sign indicating number of j need punch, and the span of parameter i is to (M from 0 _{Ack, j}-1).Symbol cnst represents a constant, and the different values of this parameter can cause punch position to present different probability density characteristicses.Symbol P _SYSRepresent a system parameters, this system parameters is relevant with frame number or subframe numbers.This system parameters adopts frame number, or subframe numbers is that system is predetermined.For the tdd systems of low spreading rate, system parameters P _SYSCan be SFN ', the be perforated subframe numbers of channel place subframe of expression.For the situation that Transmission Time Interval in the tdd systems of low spreading rate is 10 milliseconds, system parameters P _SYSBoth can be SFN ', the be perforated subframe numbers of channel place subframe of expression; Can be again SFN, the be perforated System Frame Number of channel place radio frames of expression.For the tdd systems of high spreading rate, system parameters P _SYSCan be SFN, the be perforated System Frame Number of channel place radio frames of expression.Operator mod represents modulo operation.

It is 5 milliseconds and 10 milliseconds of both of these cases that above-described random site drilling method goes for Transmission Time Interval.

Among the present invention, being provided with of constant cnst must meet the following conditions:

First condition, constant cnst should with the bit number N of the data division of down channel sign indicating number _{Data, j}Prime number each other.The value setting of constant cnst must be satisfied this condition.The constant cnst value that meets this condition can guarantee as far as possible that punch position can obey even distribution.The bit number N of the data division of down channel sign indicating number _{Data, j}Difference according to its time slot format can be got different values.For receiving terminal, the bit number of the data division of down channel sign indicating number was known before decoding in advance.In a certain transmission time unit of considering, the designated user terminal may be distributed a plurality of down channel sign indicating numbers, and the bit number of the data division of these down channel sign indicating numbers may be different, constant cnst should with these possible bit numbers prime number each other all.

Second condition, it is too small that constant cnst should value.According to the size of the bit number of the data division of down channel sign indicating number, to constant cnst get median size or value bigger than normal can two in the adjacent transmission time unit punch position of same channel code scatter as far as possible.

Parameter c nst can also can notify the UE symbol by broadcast channel in real time in Node B and UE end predetermined fixed.

Parameter P no matter _SYSBe also System Frame Number of subframe numbers, this parameter all is the system parameters that Node B and UE two ends are all known.

In step 204 of the present invention, Node B need be numbered up coded combination transmission channel.The numbering mechanism of the up coded combination transmission channel that the present invention proposes can be described below:

(1) that only finishes transmission and support the up coded combination transmission channel of HARQ technology just to be numbered in same transmission time unit.

(2) for each user terminal, all are finished transmission and support the up coded combination transmission channel of HARQ technology all must be numbered in the transmission time unit.

(3) numbering of the associated up coded combination transmission channel of the spreading code that minimum spread spectrum sequence number is little is little.

Minimum spread spectrum sequence number be from a spread spectrum sequence number group that the up coded combination transmission channel of a certain appointment is associated the minimum value picked out.This spread spectrum sequence number group is to be made of the pairing spread spectrum sequence number of each spreading code that is associated with the up coded combination transmission channel of a certain appointment.

Each up coded combination transmission channel can distribute one or more spreading codes, and each spreading code all has a spread spectrum sequence number.This spread spectrum sequence number can be known according to present existing standard.Up coded combination transmission channel will be numbered according to the spread spectrum sequence number of a plurality of spreading codes that are assigned with, and is that basis minimum spread spectrum sequence number wherein is numbered.

If the minimum spread spectrum sequence number that is associated with certain up coded combination transmission channel is less than the minimum spread spectrum sequence number that is associated with another up coded combination transmission channel, the numbering of this up coded combination transmission channel is just less than the numbering of another up coded combination transmission channel so.

More than numbering mechanism is at a designated user terminal.If a plurality of user terminals are arranged, can utilize above numbering that the up CCTrCH of each user terminal is numbered.In the present invention, the numbering of up CCTrCH can be since 0, but is not limited to since 0.

Article one in the up CCTrCH numbering of the present invention mechanism is emphasized the up CCTrCH that participates in numbering end of transmission.This is because in the present invention, only specifying punch position to transmit the numbering that just need use up CCTrCH in the process of descending answer signal in step 205.If support the up CCTrCH of HARQ not have end of transmission, Node B can not be this up CCTrCH generation answer signal so, let alone the transmission answer signal, therefore need not to be numbered for the up CCTrCH that does not have end of transmission.

If support that the Transmission Time Interval of the up CCTrCH of HARQ technology is 5 milliseconds, the transmission time unit is a subframe so, supports the up CCTrCH of HARQ technology promptly to finish transmission in a subframe in a transmission time unit.Node B just can produce corresponding answer signal to each up CCTrCH after receiving the interior data of this subframe, and corresponding answer signal must feed back to UE.Therefore in this case, Node B must be numbered same subframe transmission and up CCTrCH support HARQ technology.

If support that the Transmission Time Interval of the up CCTrCH of HARQ technology is 10 milliseconds, the transmission time unit is a radio frames so, and up CCTrCH promptly could transmit in a radio frames in a transmission time unit.Therefore in this case, Node B must be numbered same radio frame transmission and up CCTrCH support HARQ technology.

In the step 205 of the present invention, Node B can be referring to shown in Figure 6 in the implementation procedure of the punch position placement ack/nack signal of appointment according to predetermined answer signal transmission plan.This process can be described below:

Step 205-1, Node B judges N _DLWith N _ULMagnitude relationship, if the former is less than the latter, execution in step 205-2 then; Otherwise execution in step 205-3.

If step 205-2 is N _DLLess than N _UL, so Node B should be numbered i up CCTrCH corresponding ack/nack signal be placed on (k+1) individual punch position to the (k+N of the down channel sign indicating number that is numbered j _ACK) transmit on the individual punch position.Wherein, the span of parameter i is to (N from 0 _UL-1).For being numbered 0 to ((N _DL-1) up CCTrCH p-1), the value of parameter k is the result of i to the p complementation, the value of parameter j is that i is divided by the value that rounds downwards after the p.For being numbered ((N _DL-1) p) to (N _UL-1) up CCTrCH, the value of parameter k is that i deducts the (N to p _DL-1) result, the value of parameter j is (N _DL-1).That is to say, the punch position that is numbered 0 down channel sign indicating number from front to back successively carrying be numbered 0 the corresponding ack/nack signal of up CCTrCH institute to (p-1); The punch position that is numbered 1 down channel sign indicating number from front to back successively carrying be numbered the up CCTrCH institute corresponding ack/nack signal of p to (2p-1); Be numbered (N _DLThe punch position of down channel sign indicating number-2) carries successively from front to back and is numbered (N _DL-2) p is to ((N _DL-1) the corresponding ack/nack signal of up CCTrCH institute p-1); The punch position of last down channel sign indicating number carries successively from front to back and is numbered (N _DL-1) p is to (N _UL-1) the corresponding ack/nack signal of up CCTrCH institute.

Fig. 7 has provided in this case, the mapping relations between the punch position of the down channel sign indicating number of the pairing ack/nack signal of up CCTrCH and this signal of transmission.

If step 205-3 is N _DLBe not less than N _UL, so Node B should be numbered i up CCTrCH corresponding ack/nack signal be placed on the 1st punch position to the N of the down channel sign indicating number that is numbered i _ACKTransmit on the individual punch position.Wherein, the span of parameter i is to (N from 0 _UL-1).That is to say for being numbered 0 to (N _UL-1) preceding N _ULIndividual down channel sign indicating number, the punch position of each down channel sign indicating number carry the corresponding ack/nack signal of up CCTrCH institute of identical numbering.The punch position carrying that is numbered 0 down channel sign indicating number is numbered the corresponding ack/nack signal of 0 up CCTrCH institute; The punch position carrying that is numbered 1 down channel sign indicating number is numbered the corresponding ack/nack signal of 1 up CCTrCH institute; Be numbered (N _ULThe punch position carrying numbering (N of down channel sign indicating number-1) _UL-1) the corresponding ack/nack signal of up CCTrCH institute.

Fig. 8 has provided in this case, the mapping relations between the punch position of the down channel sign indicating number of the pairing ack/nack signal of up CCTrCH and this signal of transmission.

Step 901, Node B determines to transmit answer signal in which transmission time unit according to the transmit timing of descending answer signal.If support that the Transmission Time Interval of the up CCTrCH of HARQ is 5 milliseconds, Node B can determine to transmit answer signal in which subframe according to the transmit timing relation so.If support that the Transmission Time Interval of the up CCTrCH of HARQ is 10 milliseconds, Node B can determine to transmit answer signal in which radio frames according to the transmit timing relation so.

Step 902, Node B is numbered spendable whole down channel sign indicating numbers in the transmission time unit of distributing to this user terminal selected transmission answer signal in step 901.

Step 903, Node B judges the total number N of channel code available in the transmission time unit of selected transmission answer signal _DLTotal number N with the up CCTrCH that in the transmission time unit that is considered, needs to feed back answer signal _ULMagnitude relationship between the two.If the former is less than the latter, i.e. N _DLLess than N _UL, then execution in step 904 is to step 908 successively, otherwise execution in step 909 is to step 913.

P _i，j＝(P _SYS×cnst+j+i)mod(N _data，j)，i＝0，Λ，(M _Ack，j-1)，j＝0，Λ，(N _UL-1)。

Step 912, Node B supports the up CCTrCH of HARQ technology to be numbered to all that transmit in the transmission time unit that is considered.

Step 913 is at N _DLBe not less than N _ULCondition under, Node B places the ACK/NACK answer signal according to predetermined ACK/NACK answer signal transmission plan at the punch position of appointment.Under this condition, Node B should be numbered i up CCTrCH corresponding ack/nack signal be placed on the 1st punch position to the N of the down channel sign indicating number that is numbered i _ACKTransmit on the individual punch position.Wherein, the span of parameter i is to (N from 0 _UL-1).

If system allows in same transmission time unit answer signal is repeated transmission, can obtain Node B so utilizes hole knockout in the transmission time unit that is considered, promptly all of transmission are supported second kind of specific implementation of the up CCTrCH feeding back downlink ack/nack signal of HARQ technology in k transmission time unit, as shown in figure 10.

Step 1001, Node B determines to transmit answer signal in which transmission time unit according to the transmit timing of descending answer signal.If support that the Transmission Time Interval of the up CCTrCH of HARQ is 5 milliseconds, Node B can determine to transmit answer signal in which subframe according to the transmit timing relation so.If support that the Transmission Time Interval of the up CCTrCH of HARQ is 10 milliseconds, Node B can determine to transmit answer signal in which radio frames according to the transmit timing relation so.

Step 1002, Node B is numbered spendable whole down channel sign indicating numbers in the transmission time unit of distributing to this user terminal 1001 transmission answer signals of selecting in step.

Step 1003, the selected all available down channel sign indicating numbers of Node B are used for transferring ACK/NACK answer signal.

Step 1004, Node B judges the total number N of channel code available in the transmission time unit of selected transmission answer signal _DLTotal number N with the up CCTrCH that in the transmission time unit that is considered, needs to feed back answer signal _ULMagnitude relationship between the two.If the former is less than the latter, i.e. N _DLLess than N _UL, then execution in step 1005 is to step 1008 successively, otherwise execution in step 1009 is to step 1015.

Step 1005 is at N _DLLess than N _ULCondition under, Node B determines that each down channel sign indicating number is the bit number that transferring ACK/the NACK answer signal need punch, and promptly determines to be numbered the bit number M that the down channel sign indicating number of j need punch _{Ack, j}, wherein the span of parameter j is to (N from 0 _DL-1).Suppose that p represents N _ULDivided by N _DLThe value that rounds downwards afterwards, promptly

So for the less (N of numbering _DL-1) individual down channel sign indicating number, each down channel sign indicating number need be destroyed N _AckThe location transmission p of a p bit ack/nack signal; For last down channel sign indicating number, need destroy N _Ack(N _UL-p (N _DL-1)) location transmission of individual bit is come transferring ACK/NACK signal.That is to say parameter M _{Ack, j}Definite process can be described below:

$M_{\mathrm{Ack},j}=\left\{\begin{array}{c}p\·N_{\mathrm{Ack}}---j=0,\mathrm{\Λ},(N_{\mathrm{DL}}-2)\\ N_{\mathrm{Ack}}\·(N_{\mathrm{UL}}-p\·(N_{\mathrm{DL}}-1\left)\right)---j=(N_{\mathrm{DL}}-1{)}^{.}\end{array}\right.$

Step 1006 is at N _DLLess than N _ULCondition under, Node B carries out punch operation according to the punching number of determining in predetermined drilling method and the step 1004 respectively to each down channel sign indicating number.Be numbered the position P of (i+1) individual punching bit of j down channel sign indicating number _{I, j}Can determine according to following formula:

P _i，j＝(P _SYS×cnst+j+i)mod(N _data，j)，i＝0，Λ，(M _Ack，j-1)，j＝0，Λ，(N _DL-1)。

Step 1007, Node B supports the up CCTrCH of HARQ technology to be numbered to all that transmit in the transmission time unit that is considered.

Step 1008 is at N _DLLess than N _ULCondition under, Node B places the ACK/NACK answer signal according to predetermined ACK/NACK answer signal transmission plan at the punch position of appointment.Node B should be numbered i up CCTrCH corresponding ack/nack signal be placed on (k+1) individual punch position to the (K+N of the down channel sign indicating number that is numbered j _ACK) transmit on the individual punch position.Wherein, the span of parameter i is to (N from 0 _UL-1).If parameter i value is less than ((D _NL-1) p), promptly for being numbered 0 to ((N _DL-1) up CCTrCH p-1), the value of parameter k is the result of i to the p complementation, the value of parameter j is that i is divided by the value that rounds downwards after the p.If parameter i value is not less than ((N _DL-1) p), promptly for being numbered ((N _DL-1) p) to (N _UL-1) up CCTrCH, the value of parameter k is that i deducts the (N to p _DL-1) result, the value of parameter j is (N _DL-1).

Step 1009 is at N _DLBe not less than N _ULCondition under, Node B determines that each down channel sign indicating number is the bit number that transferring ACK/the NACK answer signal need punch, and promptly determines to be numbered the bit number M that the down channel sign indicating number of j need punch _{Ack, j}, wherein the span of parameter j is to (N from 0 _DL-1).The number that each selected down channel sign indicating number need punch is bit number that ack/nack signal is required of expression.That is to say that Node B determines parameter M _{Ack, j}Value be N _Ack

Step 1010 is at N _DLBe not less than N _ULCondition under, Node B carries out punch operation according to the punching number of determining in predetermined drilling method and the step 1009 respectively to each down channel sign indicating number.Be numbered the position P of (i+1) individual punching bit of j down channel sign indicating number _{I, j}Can determine according to following formula:

P _i，j＝(P _SYS×cnst+j+i)mod(N _data，j)，i＝0，Λ，(M _Ack，j-1)，j＝0，Λ，(N _DL-1)。

Step 1011, Node B supports the up CCTrCH of HARQ technology to be numbered to all that transmit in the transmission time unit that is considered.

Step 1012, Node B judges the total number N of channel code available in the transmission time unit of selected transmission answer signal _DLWhether equate with the total number of the up CCTrCH that in the transmission time unit that is considered, needs to feed back answer signal.If the two is equal, i.e. N _DLEqual N _UL, execution in step 1013 successively then; If the former is greater than the latter, i.e. N _DLGreater than N _UL, otherwise execution in step 1014.

Step 1013 is at N _DLEqual N _ULCondition under, Node B places the ACK/NACK answer signal according to predetermined ACK/NACK answer signal transmission plan at the punch position of appointment.Under this condition, Node B should be numbered i up CCTrCH corresponding ack/nack signal be placed on the 1st punch position to the N of the down channel sign indicating number that is numbered i _ACKTransmit on the individual punch position.Wherein, the span of parameter i is to (N from 0 _UL-1).

Step 1014 is at N _DLGreater than N _ULCondition under, Node B places the ACK/NACK answer signal according to predetermined ACK/NACK answer signal transmission plan at the punch position of appointment.Under this condition, predetermined ACK/NACK answer signal transmission plan is described below: the 1st punch position to the N that is numbered the down channel sign indicating number of j _AckCarrying is numbered the corresponding ack/nack signal of up CCTrCH institute of i on the individual punch position.Wherein, the span of parameter j is to (N from 0 _DL-1), the value of parameter i is that j is to N _ULThe result of complementation, its span are to (N from 0 _UL-1).That is to say for being numbered 0 to (N _UL-1) preceding N _ULIndividual down channel sign indicating number, the punch position of each down channel sign indicating number carry the corresponding ack/nack signal of up CCTrCH institute of identical numbering.Numbering is greater than (N _UL-1) down channel sign indicating number repeats to carry the ack/nack signal of front successively.Such as, be numbered N _ULThe punch position carrying of down channel sign indicating number be numbered 0 the corresponding ack/nack signal of up CCTrCH institute.

Figure 11 has provided in this case, the mapping relations between the punch position of the down channel sign indicating number of the pairing ack/nack signal of up CCTrCH and this signal of transmission.

Node B utilizes the main difference part of two kinds of implementation procedures of hole knockout transmission answer signal to be at N _DLGreater than N _ULCondition under, the quantity difference of the down channel sign indicating number of the selected transmission of Node B answer signal.In first kind of scheme, Node B only selects to be numbered 0 to (N _UL-1) preceding N _ULIndividual down channel sign indicating number transmits answer signal, and these down channel sign indicating numbers are carried out punch operation.In this scheme, each answer signal transmission primaries.Yet in second kind of scheme, Node B selects whole available down channel sign indicating numbers to transmit answer signal, and all down channel sign indicating numbers are carried out punch operation.In this scheme, each answer signal is transmission primaries at least.

Among the present invention, in the descending answer signal that UE determines in (k+n) individual transmission time unit transmission and the transmission time unit that is considered, promptly the process of the mapping relations between the up CCTrCH that transmits in k transmission time unit can be referring to Figure 12.The basic performing step of this process can be described below:

Step 1201, UE to receive in same transmission time unit, promptly in (k+n) individual transmission time unit the transmission the down channel sign indicating number be numbered.

Step 1202, UE according to the total number of the down channel sign indicating number of transmission (k+n) individual transmission time unit in be considered in the transmission time unit, the relative size of total number that promptly needs to feed back the up CCTrCH of answer signal in k transmission time unit concerns and predefined drilling method is determined the punch position information of the down channel sign indicating number bearing downlink answer signal that transmits in (k+n) individual transmission time unit and the total number of the descending ack/nack signal that carries in this transmission time unit.

Step 1203, UE is numbered the descending ack/nack signal that each punch position carried.

Step 1204, UE is in the transmission time unit that is considered, and promptly all in k transmission time unit support the up CCTrCH of HARQ technology to be numbered.

Step 1205, UE determines both mapping relations according to the mapping method between predefined answer signal and the up CCTrCH.

Above step is at a designated user terminal.If a plurality of user terminals are arranged, can as above operate respectively to confirm the mapping relations between the answer signal and up CCTrCH separately at each user terminal.Wherein step 1204 can be carried out step 1205 optional position before.

In step 1201 of the present invention, UE holds the numbering mechanism of up CCTrCH to hold the numbering mechanism of up CCTrCH identical with NodeB.

In step 1203 of the present invention, the numbering mechanism of descending ack/nack signal is described below:

1. for each user terminal, all ack/nack signals that transmit in same transmission time unit must be numbered.

2. in same transmission time unit, the numbering of the ack/nack signal of transmission is less than the numbering of the ack/nack signal that transmits thereafter earlier.If prior to the transmission time slot that another ack/nack signal occupied, the numbering of this ack/nack signal is just less than the numbering of another ack/nack signal so on time-domain for the shared transmission time slot of some ack/nack signals.

3. in same code channel, the numbering of the ack/nack signal of transmission is less than the numbering of the ack/nack signal that transmits thereafter earlier.

4. in same descending time slot, the numbering of the ack/nack signal that spreading code transmitted that the spread spectrum sequence number is little is transmitted the numbering of corresponding ack/nack signal less than the bigger spreading code of spread spectrum sequence number.

If a user terminal is assigned with a plurality of spreading codes in same time slot, the numbering of the ack/nack signal that spreading code transmitted that the spread spectrum sequence number is little is less than the numbering of the bigger ack/nack signal that spreading code transmitted of spread spectrum sequence number so.

Can be consistent with scheme that the spread spectrum sequence number of spreading code is numbered in the at present existing standard for the spread spectrum sequence number of the spreading code of mentioning in the above numbering mechanism.In the present invention, the numbering of descending answer signal can be since 0, but is not limited to since 0.

In step 1204 of the present invention, the numbering mechanism of UE end down channel sign indicating number is identical with the numbering mechanism of NodeB end down channel sign indicating number.

In step 1205 of the present invention, the mapping method between predefined answer signal and the up CCTrCH is described below: for each user terminal, the descending ack/nack signal that is numbered i is and the relevant answer signal of up CCTrCH that is numbered j.Wherein, the span of parameter i is 0 to (M _Ack-1), j is that i is to N _ULGet the result of surplus operation.M _AckThe total number of the descending ack/nack signal that expression receives, this parameter is determined by step 1202.Parameter N _ULExpress support for the total number of the up coded combination transmission channel of HARQ technology.Wherein, parameter M _AckMust be not less than N _UL

If not allowing, system in same transmission time unit, do not repeat to transmit same ACK/NACK answer signal, utilize first kind of implementation of hole knockout transferring ACK/NACK answer signal so at the Node B end that proposes among the present invention, the present invention proposes UE definite response signal and be considered in the transmission time unit, be i.e. first implementation of the process of the mapping relations between the up CCTrCH in k transmission time unit.The realization block diagram of this scheme can be referring to Figure 13.The concrete steps of this implementation can be described below:

Step 1408 is at N _DLLess than N _ULCondition under, Node B places the ACK/NACK answer signal according to predetermined ACK/NACK answer signal transmission plan at the punch position of appointment.Node B should be numbered i up CCTrCH corresponding ack/nack signal be placed on (k+1) individual punch position to the (k+N of the down channel sign indicating number that is numbered j _ACK) transmit on the individual punch position.Wherein, the span of parameter i is to (N from 0 _UL-1).If parameter i value is less than ((N _DL-1) p), promptly for being numbered 0 to ((N _DL-1) up CCTrCH p-1), the value of parameter k is the result of i to the p complementation, the value of parameter j is that i is divided by the value that rounds downwards after the p.If parameter i value is not less than ((N _DL-1) p), promptly for being numbered ((N _DL-1) p) to (N _UL-1) up CCTrCH, the value of parameter k is that i deducts the (N to p _DL-1) result, the value of parameter j is (N _DL-1).

Step 1409 is at N _DLBe not less than N _ULCondition under, Node B is selected to be numbered 0 to (N _UL-1) preceding N _ULIndividual down channel sign indicating number is used for transferring ACK/NACK answer signal.

Step 1410 is at N _DLBe not less than N _ULCondition under, Node B is that each selected in the step 1409 down channel sign indicating number is defined as the bit number that transferring ACK/the NACK answer signal need punch respectively, promptly determines to be numbered the bit number M that the down channel sign indicating number of j need punch _{Ack, j}, wherein the span of parameter j is to (N from 0 _UL-1).The number that each selected down channel sign indicating number need punch is bit number that ack/nack signal is required of expression.That is to say that Node B determines parameter M _{Ack, j}Value be N _Ack

Step 1411 is at N _DLBe not less than N _ULCondition under, Node B carries out punch operation according to the punching number of determining in predetermined drilling method and the step 1410 respectively to the selected down channel sign indicating number of each step 1409.Be numbered the position P of (i+1) individual punching bit of j down channel sign indicating number _{I, j}Can determine according to following formula:

P _i，j＝(pcnst+i)，i＝0，Λ，(M _Ack，j-1)，j＝0，Λ，(N _UL-1)。

Step 1413 is at N _DLBe not less than N _ULCondition under, Node B places the ACK/NACK answer signal according to predetermined ACK/NACK answer signal transmission plan at the punch position of appointment.Under this condition, Node B should be numbered i up CCTrCH corresponding ack/nack signal be placed on the 1st punch position to the N of the down channel sign indicating number that is numbered i _ACKTransmit on the individual punch position.Wherein, the span of parameter i is to (N from 0 _UL-1).

If hole knockout is fixed position punching and system allows repeat to transmit same ACK/NACK answer signal in same transmission time unit, Node B as shown in figure 16 utilizes the 4th kind of implementation procedure of hole knockout transmission answer signal to be described below:

Step 1501, Node B determines to transmit answer signal in which transmission time unit according to the transmit timing of descending answer signal.If up CCTrCH finishes transmission in k transmission time unit, Node B can determine transmission answer signal in (k+n) individual transmission time unit according to the transmit timing relation so, has promptly determined parameter n.

So for the less (N of numbering _DL-1) individual down channel sign indicating number, each down channel sign indicating number need be destroyed N _AckThe location transmission p of a p bit ack/nack signal; For last down channel sign indicating number, need destroy N _Ack(N _UL-p (N _DL-1)) location transmission of individual bit is come transferring ACK/NACK signal.That is to say parameter M _{Ack, j}Definite process can be described below:

$M_{\mathrm{Ack},j}=\left\{\begin{array}{c}p\·N_{\mathrm{Ack}}---j=0,\mathrm{\Λ},(N_{\mathrm{DL}}-2)\\ N_{\mathrm{Ack}}\·(N_{\mathrm{UL}}-p\·(N_{\mathrm{DL}}-1\left)\right)---j=(N_{\mathrm{DL}}-1{)}^{.}\end{array}\right.$

Step 1506 is at N _DLLess than N _ULCondition under, Node B carries out punch operation according to the punching number of determining in predetermined drilling method and the step 904 respectively to each down channel sign indicating number.Be numbered the position P of (i+1) individual punching bit of j down channel sign indicating number _{I, j}Can determine according to following formula:
