Description

Communicator
Technical field
The present invention relates to a kind of communicator, particularly a kind of energy realization is applicable to the communicator of the coding/decoding mathematical algorithm of wireless communication system.
Background technology
The existing communicator (base station and mobile radio station) that uses in the mobile communication is described.
The base station not only and mobile radio station between communicate, but also and epigyny device between receiving and transmitting signal.For example, receive base station from the data of epigyny device in interface portion with the agreement of interface as terminal, from the desired data of the extracting data that receives.
After the encoded processing of the data of extracting and the modulation treatment, its wireless frequency is sent from antenna as wireless signal by up-conversion (upwards conversion frequency).
On the other hand, the mobile radio station that receives the wireless signal that sends from described antenna, to offer base band part after this wireless signal down-conversion (downward conversion frequency), in base band part, after demodulation process and decoding processing, in interface portion, be transformed into the agreement that conforms to upper application.This process is called down link.
Similarly, in the mobile radio station of the data that in receiving upper application, produce, in interface portion with the agreement of interface as terminal, from the desired data of the extracting data that receives.
The data of extracting are encoded, after the modulation treatment, its wireless frequency is sent from antenna as wireless signal by up-conversion.
On the other hand, the base station that receives the wireless signal that sends from described antenna, to offer base band part after this wireless signal down-conversion (downward conversion frequency), in base band part, after demodulation process and decoding processing, in interface portion, be transformed into the agreement that conforms to epigyny device.This process is called up link.
Owing to usually communicating simultaneously with a plurality of mobile radio stations in the base station, therefore implement concurrently coding processing and decoding and process.
Concrete example as above-mentioned existing communicator, (the FDD mode: communicator Frequency Division Duplex system (frequency division duplex system)), (third generation partner program: specifications 3rd Generation PartnershipProject) (non-patent literature 1) describe according to the 3GPP as the standardization project of 3-G (Generation Three mobile communication system) for W-CDMA (Wideband Code Division Multiple Access (WCDMA) (Wide-band Code Division Multiple Access)) mobile radio system.
For example, the output of the interface portion of base station is called as transmission channel, the block size of this transmission channel, the number of blocks of transmission channel so long as and epigyny device between in the licensed scope, just can not according to and mobile radio station between preset program change.The scope that this is licensed is called TFS (TFS Transport Format Set: Transport Format Set), the indication that specifically sends what content in this set is called transmission channel format indication (TFI:Transport Format Indicator (transformat indication)).
The least unit that in addition, TFI can be changed is called TTI (Transmission Time Interval: Transmission TimeInterval), become the unit for coding.In addition, in the wireless channel, can carry out a plurality of transmission channels multiplexedly, be indicated by epigyny device in the combination of the desirable TFI of each transmission channel and can carry out multiplexed combination.
In addition, the combination of above-mentioned desirable TFI is called as TFC, and (transformat combination: Transport FormatCombination), it indicates available TFCI (transformat combination indication: Transport FormatCombination Indicator) represent.In addition, the scope of above-mentioned desirable TFC is called as TFCS (transport format combination set: Transport Format Combination Set), represent the scope that a wireless channel can change not according to preset program between base station and mobile radio station.
For example, in upper layer, transmission channel a and transmission channel b are carried out in the multiplexed situation, each transmission channel transmits with the form of transport channel block, to the additional TFI of a TTI.In addition, sometimes there are a plurality of transmission blocks among a TTI.At this moment, to the additional TFI of this one transmission block.Then, in physical channel this transmission block is carried out when multiplexed, its combination one by one represents with TFCI.
Then, as the concrete action in the above-mentioned existing communicator, the MBMS (multimedia broadcast multi-broadcasting business: Multimedia Broadcast Multicast Service), describe according to non-patent literature 2 to stipulating in the 3GPP standard for example.
MBMS is following communication mode, namely, sending to from the base station the down link of mobile radio station, from existing SCCPCH (Secondary Common Control Physical Channel: Secondary Common Control PhysicalChannel) different, consist of a wireless channel by a kind of transmission channel, by broadcast message (Broadcast Data: broadcast data) is provided like this.
Among the MBMS, identical with the downlink channel of stipulating in the 3GPP standard in the base station, after the transmission encoded processing of data and the modulation treatment, its wireless frequency further by up-conversion (upwards conversion frequency), sends from antenna.
In addition, in the mobile radio station that receives the wireless channel data that MBMS uses, this signal is carried out down-conversion (downward conversion frequency) in base band part, further after demodulation process and decoding processing, in interface portion, be transformed into the agreement that conforms to upper application, as transport channel data, data are passed to upper application.
Non-patent literature 1:3GPP TS25.212, V6.8.0 (2006-06), multiplexed and chnnel coding (Multiplexing and channel coding) (FDD), 4.2.4-4.2.12.
Non-patent literature 2:3GPP TR25.993, the RAB (RABs) that general land wireless access (UTRA) is supported and the typical case (Typical examples of Radio AccessBearers (RABs) and Radio Bearers (RBs) supported by Universal Terrestrial RadioAccess (UTRA)) of radio bearer (RBs), 7.2.10-7.2.16
In the existing communicator of above-mentioned illustrated FDD mode, process and decipher in the processing at coding, owing to only have same mathematical algorithm, if therefore will consist of with the mathematical algorithm with versatility, then have the problem that the apparatus structure scale is large and power consumption increases.
In addition, when consisting of a wireless channel with a transmission channel, the data of the transmission channel that sends from epigyny device so long as and epigyny device between in the licensed scope (in the TFS), just can not according to and mobile radio station between preset program change.Yet, among the TTI of the least unit that can change as TFI, for the wireless channel data that the data that send with the transmission channel that becomes object consist of, need to calculate TFCI, need to according to this TFCI processing of encoding, there be huge problem of processing time.
In addition, when consisting of a wireless channel with a plurality of transmission channels, the data of a plurality of transmission channels that send from epigyny device so long as and epigyny device between in the licensed scope (in the TFS), just can not according to and mobile radio station between preset program change.Yet, be respectively to be that the unit of the TFI minimum that can change sends data with TTI because of the data of transmission channel, so the data of these a plurality of transmission channels are carried out multiplexed, generate the data of wireless channel.Therefore, need to carry out the timing adjustment between a plurality of transmission channels, need in addition the TFI value according to each multiplexed transmission channel, calculate for the required TFCI of the transmission of carrying out the wireless channel data, and according to this TFCI processing of encoding, there is huge problem of processing time.
In addition, among the MBMS, owing to need to generate the radio channels certificate with the diverse transmission channel of transmission channel that consists of existing SCCPCH with TTI, therefore compare with existing SCCPCH, the desirable scope of TFI also increases.Thus, for the desirable scope of the required TFCI of the transmission of carrying out the wireless channel data also increases, need the processing of encoding according to the TFCI that calculates, have huge problem of processing time.

Then, the method that generates the radio channels certificate with the data that keep in the timing adjustment section 132 shown in Figure 6, by shining upon handling part 134 is described.
At first, the mapping form selection portion 133 for the mapping form of selecting mapping handling part 134 to use is described.
Among Fig. 6, remain in the data in the data buffer 1321 of timing adjustment section 132, the data as corresponding with transmission channel TrCH#a maintain CFN=4,5,6,7 data are as the data corresponding with transmission channel TrCH#b, maintain CFN=4,6 data as the data corresponding with transmission channel TrCH#c, maintain the data of CFN=4.
Use Fig. 7, illustrate to be used for selection in order to generate the CFN=4 of wireless channel data, 5,6,7 required CFN=4, the computational methods of the TFCI of the mapping form of each CFN of 5,6,7 are with the processing as mapping form selection portion 133.
As shown in Figure 7, the data of the CFN=4 of wireless channel data be the CFN=4 of data, TrCH#b with the CFN=4 of transmission channel TrCH#a data, and the data of the CFN=4 of TrCH#c generate.
At this moment, use the TFI of each transmission channel, calculate the required TFCI of timing of the CFN=4 of wireless channel data.Namely, use is according to the TFI of the data of the CFN=4 of the transmission channel TrCH#a (=a4) TFI of the data of the CFN=4 of information, transmission channel TrCH#b (=b4) information, and the TFI of the data of the CFN=4 of the transmission channel TrCH#c (=c4) TFCI4 that calculates of information, from preprepared form group, select the required mapping form of CFN=4.
In addition, the TFCI that the timing of the CFN=5 of wireless channel data is required, to use TFI according to the data of the CFN=5 of the transmission channel TrCH#a (=a5) TFI of the data of the CFN=4 of information, transmission channel TrCH#b (=b4) information, and the TFI of the data of the CFN=4 of the transmission channel TrCH#c (=c4) TFCI5 that calculates of information, from preprepared form group, select the required mapping form of CFN=5.
In addition, the TFCI that the timing of the CFN=6 of wireless channel data is required, to use TFI according to the data of the CFN=6 of the transmission channel TrCH#a (=a6) TFI of the data of the CFN=6 of information, transmission channel TrCH#b (=b6) information, and the TFI of the data of the CFN=4 of the transmission channel TrCH#c (=c4) TFCI6 that calculates of information, from preprepared form group, select the required mapping form of CFN=6.
In addition, the TFCI that the timing of the CFN=7 of wireless channel data is required, to use TFI according to the data of the CFN=7 of the transmission channel TrCH#a (=a7) TFI of the data of the CFN=6 of information, transmission channel TrCH#b (=b6) information, and the TFI of the data of the CFN=4 of the transmission channel TrCH#c (=c4) TFCI7 that calculates of information, from preprepared form group, select the required mapping form of CFN=7.
Then, the mapping form of selecting in the mapping form selection portion 133 is described.This mapping form have for the data of timing adjustment section 132, be transformed into the information of the form of wireless channel data as shown in Figure 8.
An example of the form of the radio frames of dedicated channel shown in Fig. 8.The length of radio frames RF is 10ms, is divided into 15 time slots till time slot #0～time slot #14.
Here, if pay close attention to i number time slot #i, then be split into each zone that " data 1 ", " data 2 ", " TPC ", " TFCI " reach " pilot tone " in a time slot, the data (DPDCH:Dedicated Physical Data Channel (Dedicated Physical Data Channel)) that are stored in the data buffer 1321 of timing adjustment section 132 are assigned to the zone that " data 1 " reach " data 2 ".In addition, the control information (DPCC:Dedicated Physical Control Channel (Dedicated Physical Control Channel)) that be used for to send the wireless channel data is assigned to the zone that " TPC ", " TFCI " reach " pilot tone ".
Then, use Fig. 9 that the data buffer 1321 that keeps in the timing adjustment section 132 is described.
Maintain the data of transmission channel TrCH#a, TrCH#b, TrCH#c in the data buffer 1321; maximum according to the desirable value of its TFI of each channel of each transmission channel; calculate the data capacity of energy pre-save in data buffer 1321, guarantee buffer.
Among Fig. 9, the data volume that illustrates when establishing transmission channel TrCH#a and getting maximum TFI value is that 20 bits, the data volume when transmission channel TrCH#b gets maximum TFI value are that 30 bits, the data volume when transmission channel TrCH#c gets maximum TFI value are the situation of 60 bits.
In fact, the data of transmission channel TrCH#a will be guaranteed CFN=4,5,6,7 four parts the 20 bits * corresponding zone of 4=80 bit institute, the data of transmission channel TrCH#b will be guaranteed CFN=4,6 two parts the 30 bits * corresponding zone of 2=60 bit institute, the data of transmission channel TrCH#c will be guaranteed 60 bits of the portion of CFN=4 * corresponding zone of 1=60 bit institute, and data buffer 1321 amounts to will guarantee 80 bits+60 bits+60 bits=corresponding zone of 200 bits institute.
Data buffer 1321 as shown in Figure 9, the maximum data capacity when considering to get maximum TFI value in each transmission channel is guaranteed buffer, and maintenance is from the address that generates according to incremental data that starts most of data.
That is, among Fig. 9, the data of 20 bits of the CFN=4 of transmission channel TrCH#a are to begin to keep successively address #0, address #1～address #19 from initial data.Similarly, the data of 20 bits of the CFN=6 of transmission channel TrCH#a are to keep address #40～address #59.In addition, the data of the CFN=4 of transmission channel TrCH#b are to keep address #80～address #109.In addition, the data of the CFN=4 of transmission channel TrCH#c are to keep till address #140～address #199.
In the above-mentioned data buffer 1321, not necessarily get maximum TFI value in each transmission channel always, as shown in Figure 9, with respect to the data capacity in the maximum of the TFI of each transmission channel, TFI does not get in the peaked situation, i.e. the CFN=5 of transmission channel TrCH#a, 7, and the CFN=6 of TrCH#b shown in situation under, although there are not data in the part shown in the shade, this moment is to the part that do not have data also extra address.
Namely, in the data of the CFN=5 of TrCH#a, although guarantee to have the corresponding data area of 20 bits institute, but the TFI during owing to CFN=5 does not get maximum, therefore as data, only has 16 bits, there are not data from address #36 to address #39, but also guarantee to have the zone for address #36 to address #39, and the data of the CFN=6 of transmission channel TrCH#a are to begin save data from address #40.
A-2-2-3. about mapping form and mapping handling part
According to above-mentioned rule, the following describes the processing in mapping form and the mapping handling part.
In the mapping handling part 134, generate the wireless channel data every 10ms.Therefore, just need mapping form every 10ms.The generation of the wireless channel data when for example, CFN=4 being described.
By the mapping form selection portion 133 of Fig. 7 as can be known, when generating the wireless channel data of CFN=4, the TFI information (TFI=a4) of the CFN=4 of choice for use transmission channel TrCH#a, the TFI information (TFI=b4) of the CFN=4 of transmission channel TrCH#b, and the mapping form used of the TFCI4 that calculates of the TFI information (TFI=c4) of the CFN=4 of transmission channel TrCH#c, and use the data of the CFN=4 of transmission channel TrCH#a, the data of the CFN=4 of transmission channel TrCH#b, and the data of the CFN=4 of transmission channel TrCH#c generate the wireless channel data of CFN=4.
Among Figure 10, data, and the data format of the wireless channel of the CFN=4 that generates of the data of the CFN=4 of transmission channel TrCH#c of the CFN=4 of data with the CFN=4 of transmission channel TrCH#a, transmission channel TrCH#b is shown.
The length of radio frames RF is 10ms, and 15 time slots till being divided into from time slot #0 to time slot #14 among Figure 10, illustrate No. 0 time slot #0.
The data of transmission channel TrCH#a, TrCH#b and TrCH#c are assigned to the usefulness " data 1 " of the data format of wireless channel, the zone shown in " data 2 ", store the data of " 0 " or " 1 " in the zone of " TFI ", " TFCI ", " pilot tone ", with the control information as fixed value.
Bit configuration example shown in Figure 10 is to implement to process bit configuration example in the situation after (L (x)) processed in the mapping of (D (x))～physical channel with the illustrated rate-matched of Fig. 2, and the result identical with using situation after compound function Z (x) shown in Figure 3 processes is shown.
Then, using the result after compound function Z (x) shown in Figure 3 processes is mapping form shown in Figure 11.
Which bit information of which transmission channel of each address assignment of the address of in the mapping form shown in Figure 11, data format corresponding to wireless channel is shown, the beginning from wireless channel being distributed successively.
Like this, to implement for the data of certain address that the variation of resulting address is that mapping form keeps as compound function Z (x) after the processing of function D (x)～L (x), by when coding with reference to this form, can carry out coding, by preparing this mapping form in advance, can shorten coding and process the time that spends.
In addition, function D (x)～L (x) processes according to the coding of the down link of 3GPP standard, by it is kept as compound function Z (x), can easily carry out the coding processing according to the down link of 3GPP standard.
In the data format of wireless channel as shown in figure 10, also contain and be called the information (" 0 " bitwise or the information of " 1 ") that " TPC ", " TFCI " reach the expression control information of " pilot tone ", in mapping form shown in Figure 11, also preserve the information relevant with this control information, the information till preserving from time slot #0 to time slot #14.
In addition, in the part of expression control information, not the address of data, and keep " 0xFF00 " of expression ' 0 ' or ' 1 ' the meaning bitwise to reach the so-called specific information of " 0xFF01 ".
Then, use Figure 10 and Figure 11, the information of mapping form is described.
Among Figure 10, in the part shown in the #0 of wireless channel address, maintain the data of address #0 of the CFN=4 of transmission channel TrCH#a, in the part shown in the #1 of wireless channel address, maintain the data of address #98 of the CFN=4 of transmission channel TrCH#b.Similarly, among the #2 of wireless channel address, maintain the data of address #182 of the CFN=4 of transmission channel TrCH#c, among the #3 of wireless channel address, maintain the data of address #156 of the CFN=4 of transmission channel TrCH#c.These keep mapping form shown in Figure 11 as the address corresponding relation corresponding with the address of the data of each transmission channel TrCH#a, TrCH#b, TrCH#c that makes the wireless channel data.
Then, use Figure 12 and Figure 13, describe for the processing in the mapping handling part 134 of not getting in the transmission channel in the less situation of maximum TFI value, data.
Mapping handling part 134 utilizes the TFCI value of this moment corresponding to the timing that sends above-mentioned illustrated mapping form, and the mapping form that use mapping form selection portion 133 is selected generates the radio channels certificate.
For example, when generating the wireless channel data of CFN=5, by the mapping form selection portion 133 of Fig. 7 as can be known, the TFI information (TFI=a5) of the CFN=5 of choice for use transmission channel TrCH#a, the TFI information (TFI=b4) of the CFN=4 of transmission channel TrCH#b, and the mapping form used of the TFCI5 that calculates of the TFI information (TFI=c4) of the CFN=4 of transmission channel TrCH#c, and the data of the CFN=5 of use transmission channel TrCH#a, the data of the CFN=4 of transmission channel TrCH#b, reach the data of the CFN=4 of transmission channel TrCH#c, generate the wireless channel data of CFN=5.
Here, as shown in Figure 9, owing to do not get maximum TFI value in the data of the CFN=5 of transmission channel TrCH#a, therefore as shown in figure 12, only have address #20 to have data till the #35 of address, there are not data in address #36 till the #39 of address.
Therefore, for when generating the wireless channel data of CFN=5, generate the example of radio channels certificate with the data of the address #36 that does not have above-mentioned data till the #39 of address, use Figure 12 describes.
Among Figure 12, identical with Figure 10, illustrate the CFN=4 of data with the CFN=5 of transmission channel TrCH#a, transmission channel TrCH#b data, and the situation of the wireless channel data that send when generating CFN=5 of the data of the CFN=4 of transmission channel TrCH#c under the bit configuration example.
Among Figure 12, will in fact not exist the data allocations of the address #37 of data to arrive wireless channel address #10.
Among Figure 13, the details of the mapping form of using in the mapping processing shown in Figure 12 is shown.Among Figure 12, as the data that are equivalent to wireless channel address #10, distribute the address #37 that does not have data, but in the mapping form of Figure 13, the part that is equivalent to wireless channel address #10 has been distributed specific information " 0xFFFF ".If this specific information is to be assigned to the information that does not in fact have the address of data, for the address that is assigned with this specific information, when reality sends the wireless channel data, make the processing that sends OFF.
Namely, in the mapping form shown in Figure 13, to each wireless channel address, except the data that maintain actual transmission, also each address is maintained and make the information that sends ON and make the information that sends OFF, make the information that sends OFF by only providing for the address that does not have data, carry out correspondence.
In addition, as the actual information that sends OFF that makes, employing remains on information in the mapping form with above-mentioned " 0xFFFF ", but as making the information that sends OFF be not limited to " 0xFFFF ".In addition, send OFF and refer to that (discontinuous transmission: Discontinuous Transmission) information is to instigate the amplitude of modulating wave to be the processing of " 0 " to so-called DTX.
In addition, reach " 0xFF01 " for " 0xFF00 " that distribute as control information, because therefore the data that physical presence sends as the information that sends ON is processed, reach " 0xFF01 " but control information is not limited to " 0xFF00 ".

B-2. device action
B-2-1. about compound function
Then, use Figure 15～Figure 24, the action of communicator 200 is described.
Figure 15 be expression with the decoding of the down link of the 3GPP standard in the W-CDMA mobile radio system (FDD mode) process, the flow chart of action when realizing with decoding section 6 shown in Figure 14, being that the contrary of coding processing that carries out in the communicator 100 (base station) of explanation in the execution mode 1 processed, is the processing that down link signal is deciphered.
In the decoding section 8 shown in Figure 14, for example when setting new communication (new paging), the TFCI that allows according to this paging also adopts compound function Z -1(x) (second processes) processed in the decoding that sends data.
Compound function Z -1(x) be that the compound function Z (x) illustrated with using Fig. 2 carries out the contrary function of processing in reverse order, among the step S31, with function L -1(x): physical channel removes mapping processing, function K -1(x): processing, function J deinterleave for the second time -1(x): physical channel concatenation is processed, function I -1(x): for the second time DTX deletion is processed, function H -1(x): transmission channel dividing processing, function G -1(x): radio frames cascade processing, function F -1(x): processing, function E deinterleave for the first time -1(x): for the first time DTX deletion is processed, function D -1(x): the order that rate de-matching is processed is processed.
After this, with function C -1(x): channel decoding (error-correcting decoding) is processed (step S32), function B -1(x): code block cascade and transmission dividing processing (step S33), function A -1(x): CRC detects the order of (step S34) and processes (first processes).
In addition, compound function Z -1(x) in, for example represent to represent as Z1 (x) for No. 1 TFCI as Z0 (x) for No. 0 TFCI.

Like this, will implement function L for the data of certain address -1(x)～D -1(x) variation of resulting address after the processing is as compound function Z -1(x) namely go mapping form to keep, by when decoding with reference to this form, can carry out decoding, go mapping form by preparing this in advance, can shorten and decipher the time that processing spends.
In addition, function L -1(x)～D -1(x) be to process according to the decoding of the down link of 3GPP standard, by with it as compound function Y -1(x) keep, can easily carry out the decoding processing according to the down link of 3GPP standard.
B-2-2. process about the concrete decoding in the decoding section
Figure 16 be illustrated in the decoding section 8 of communicator shown in Figure 14 200 (mobile radio station), the block diagram of the concrete structure when carrying out with the illustrated processing of Figure 15, and will also illustrate with the structure of the C of coding section of the structural correspondence of decoding section 8.In addition, for the structure of the C of coding section, in execution mode 3, describe afterwards.
As shown in figure 16, when consisting of a wireless channel with a plurality of transmission channels, need to arrange each transmission channel and implement channel decoding processing (C -1(x)), code block cascade and transmission block dividing processing (B -1(x)) and CRC detect (A -1(x)) channel decoding section 184 is provided with a plurality of channel decoding section 184 in the decoding section 8.Then, will send to interface portion A with the data after each channel decoding section 184 decoding.
The data that receive with mobile radio station are gone in the mapping form selection portion 181 decoding section 8, and the TFCI according to the data that receive selects mapping form, and notice removes to shine upon handling part 182.Go to shine upon in the handling part 182, use by the mapping form of going of going mapping form selection portion 181 notices, data are stored into the data buffer of timing adjustment section 183.
B-2-2-1. the data in the timing adjustment section keep
Among Figure 17 take the situation that consists of a wireless channel with three transmission channels as example, schematically expression spend mapping handling part 182 implement to go to shine upon process after, data are at the state that sends in the way to timing adjustment section 183.
Among Figure 17, the wireless channel data that receive are sent to every 10ms shines upon handling part 182, TFCI according to the wireless channel data that receive, and make and spend the mapping form of going that mapping form selection portion 181 selects, after data are cut apart take transmission channel as unit, send to the data buffer 1831 of timing adjustment section 183.
At this moment, among the transmission channel TrCH#a, data 1811 are sent to timing adjustment section 183 among the data after take 10ms as processed in units, for example Figure 17.In addition, comprise CFN=8 in the data 1811,9,10,11 data.
Similarly, among the transmission channel TrCH#b, data 1812 are sent to timing adjustment section 183.In addition, comprise CFN=8 in the data 1812,9,10,11 data.
In addition, similarly, among the transmission channel TrCH#c, data 1813 are sent to timing adjustment section 183.In addition, comprise CFN=8 in the data 1813,9,10,11 data.
In the timing adjustment section 183, receive the different decoding data of TTI, according to a plurality of transmission channels, different TTI separately, calculate the TTI that is equivalent to least common multiple, the corresponding data buffer 1831 of TTI institute by guaranteeing to calculate carries out timing adjustment.
In the timing adjustment section 183 shown in Figure 17, the hold mode of the data in the data buffer 1831 when being illustrated in the data of three different transmission channel TrCH#a～TrCH#c of the TTI that receives separately.
B-2-2-2. about going mapping form and removing to shine upon handling part
Use Figure 18 that the processing of going to shine upon in the handling part 182 is described.The length of the radio frames RF of the wireless channel that receives is 10ms, and 15 time slots till being divided into from time slot #0 to time slot #14 among Figure 17, illustrate No. 0 time slot #0.
As shown in figure 18, the data in the zone shown in the usefulness of the data format of wireless channel " data 1 ", " data 2 " are assigned with the data as transmission channel TrCH#a, TrCH#b and TrCH#c.In addition, store the data of " 0 " or " 1 " in the zone of " TFI ", " TFCI ", " pilot tone ", with as control information.
For example, the information of the address #0 of wireless channel data is assigned with the data as the address #0 of the CFN=4 of transmission channel TrCH#a, the information of the address #1 of wireless channel data is assigned with the data as the address #1 of the CFN=4 of transmission channel TrCH#b, and the information of the address #2 of wireless channel data is assigned with the data as the address #1 of the CFN=4 of transmission channel TrCH#c.
Among Figure 19～Figure 21, expression is shone upon shown in Figure 180 going and is processed the example that goes mapping form shown in each channel of each transmission channel TrCH#a, TrCH#b and TrCH#c.
Because radio channels according to this 10ms is that unit receives, and go mapping to process take 10ms as unit, therefore for example be respectively among transmission channel TrCH#a, the TrCH#b and TrCH#c of 10ms, 20ms and 40ms establishing TTI, the information converting that going separately comprises in the mapping form is different.
Namely, its structure is, in the situation of transmission channel TrCH#a, as shown in figure 19, comprise whole information converting of processing among the 10ms, namely for the information converting of address #0～#19 of transmission channel TrCH#a, and among the transmission channel TrCH#b, as shown in figure 20, half the information converting of 10ms part that only comprises 20ms part, namely for the information converting of address #0～#14 of transmission channel TrCH#b, among the transmission channel TrCH#c, as shown in figure 21, the information converting that only comprises 10ms part of 1/4 of 40ms part, namely for the information converting of address #0～#14 of transmission channel TrCH#c.
Here, because the data of the CFN=4 of transmission channel TrCH#a all get all the ready, so in the channel decoding section 184, implement channel decoding and process (C -1(x)), code block cascade and transmission block dividing processing (B -1(x)) and CRC detect (A -1(x)) after, data are sent to interface portion A.
On the other hand, about transmission channel TrCH#b and TrCH#c, because the data of CFN=4 are not got all the ready, therefore proceed the mapping of going of the wireless channel data of CFN=5 and process, come the completion data.
Among Figure 22～Figure 24, illustrate respectively to after CFN=4, when the wireless channel data of CFN=5 are gone to shine upon and are processed, each transmission channel TrCH#a, TrCH#b and TrCH#c go mapping form.
At this moment, owing to also only have the data of 10ms part of each transmission channel to comprise information converting, so among transmission channel TrCH#a, TrCH#b and the TrCH#c, the information converting that going separately comprises in the mapping form is different.
Namely, in the situation of transmission channel TrCH#a, as shown in figure 22, comprise whole information convertings of processing among the 10ms, namely for the conversion of address #0～#19 of the CFN=5 of transmission channel TrCH#a, among the transmission channel TrCH#b, as shown in figure 23, only comprise the information converting for address #15～#29 of CFN=4, be added together data that just can conversion 20ms part with the data of 10ms part shown in Figure 20.
In addition, among the transmission channel TrCH#c, as shown in figure 24, only comprise the information converting of 10ms part of 1/4 of 40ms part, namely for the information converting of address #15～#29 of transmission channel TrCH#c, be added together the data of 20ms part of 1/2 that just can conversion 40ms part with the data of 10ms part shown in Figure 21.
At this moment, because the data of the CFN=4 of the data of the CFN=5 of transmission channel TrCH#a and transmission channel TrCH#b are all got all the ready, therefore in channel decoding section 184, implement channel decoding and process (C -1(x)), code block cascade and transmission block dividing processing (B -1(x)) and CRC detect (A -1(x)) after, data are sent to interface portion A.
In addition, about transmission channel TrCH#c, because the data of CFN=4 are not got all the ready, therefore proceed the mapping of going of the wireless channel data of CFN=6 and process, come the completion data.
Though omit diagram, the going of the wireless channel data of CFN=6 can make the data of the CFN=6 of transmission channel TrCH#a get all the ready during mapping processes, and be same as described above, in channel decoding section 184, implements channel decoding and process (C -1(x)), code block cascade and transmission block dividing processing (B -1(x)) and CRC detect (A -1(x)) after, data are sent to interface portion A.
In addition, going in the mapping processing of the wireless channel data of CFN=7, the data of the CFN=4 of the data of CFN=6 of data, transmission channel TrCH#b of the CFN=7 of transmission channel TrCH#a and transmission channel TrCH#c are all got all the ready, each channel to each transmission channel, in channel decoding section 184, implement channel decoding and process (C -1(x)), code block cascade and transmission block dividing processing (B -1(x)) and CRC detect (A -1(x)) after, data are sent to interface portion A.

C-2-1. about compound function
Then, use Figure 25～Figure 27, the action when communicator 200 used as the mobile radio station of up link is described.
Figure 25 be expression with the coding of the up link of the 3GPP standard in the W-CDMA mobile radio system (FDD mode) process, the flow chart of action when realizing with the C of coding section shown in Figure 14, Figure 26 is the flow chart that describes the coding processing among the coding C of section in detail.
Among the C of coding section shown in Figure 14, for example in the situation of setting new communication (new paging), the TFCI that allows according to this new paging and the coding that adopts compound function to send data are processed.
Specifically, at first, for sending data, implement the processing (first processes) for indeclinable parameter in communication.
That is, as shown in figure 25, implement: among the step S41, the CRC additional (m (x)) of the CRC code of additional mistake for detection of data; Among the step S42, transmission block cascade and code block cut apart (n (x)); And processing among the step S43, chnnel coding (p (x)).Here, among the CRC additional (m (x)), determine transmission block size and CRC size.
After this, to each TFCI, indeclinable parameter is fixed, and process (second processes) for Varying parameters utilization in communication as the coding of compound function Y (x) and generate wireless transmission data (step S44～S51).
