Embodiment

The embodiment that discloses is accompanied by illustration, but in some cases, possible embodiment is not shown in the accompanying drawing.Under the possibility situation, the components identical numbering is the identical or similar part of representative in the icon.Can use the data that can be transmitted, receive and/or store according to disclosed embodiment in this use alternately relevant for " data ", " content ", " information " and similar word with expression.

As above-mentioned mentioned, multi-input multi output (MIMO) technology is to be applied on a plurality of antennas of transmission end and receiving terminal to increase transmission rate to reach a plurality of independent data streams (data streams) of synchronous driving.Be employed in and formulate in detail in the 4th generation wireless communication standard that the multi-input multi output mode institute of IEEE802.16e standard combines according to the technology of mentioned above principle.No matter this particular technology, the structure of multi-input multi output transmission are based on a single codeword (singlecodeword is called for short SCW) structure or code word more than (multiple codeword is called for short MCW) structure.

At the single codeword structure, this structure comprises that a modulation of single group of modulation stratum (modulation order) and code rate (coding rate) and encoding mechanism (modulation and codingscheme is called for short MCS) use in the transmission end.In other words, many codeword structures then use the modulation and the encoding mechanism (for example, two groups) of many groups.According to one of above-mentioned both technology, be useful in some parameter of transmission end, for example modulation stratum and code rate will be used to improve transmission usefulness.Because many code words (MCW) have the more effective parameter of revising of multipotency, so many code words can provide more gain of performance (performance gain) than single codeword transmission structure.Yet this structure may need extra feedback signal amount (feedback overhead), and such situation can cause reducing Zong Pin Spectrum benefit (spectral efficiency).

Fig. 1 is presented to have precoding (precoding) uses down, based on the transmission end calcspar of the spatial multiplexing multi-input multi output (SCW-based spatial multiplexing MIMO) of single codeword transmission structure.The transmission end comprises an encoder (encoder) 126, one passage interleaver (channel interleaver) 128, one rate matchers (rate matcher) 130, the one first corresponder of symbol (symbol mapper) 132, one code word is to crossfire corresponder (codeword (CW)-to-stream mapper) 134, with a precoder (precoder) 136 of a plurality of antenna ports (antenna port) binding, and a controller (controller) 138.Encoder 126 receives the code word block (code block) that contains information bit 124 in the bit crossfire.Then, the information bit 124 that encoder 126 is encoded and received according to an encoding mechanism, for example, utilize 1/3 code check turbine code with end bit newly-increased (tail bit addition) (1/3-rate turbocode, TC).

The turbine code (TC) or the turbine code that circles round (convolutional turbo code, be called for short CTC) use one double binary system ring-type recursive system convolution code (double binary circular recursivesystematic convolutional code, be called for short double binary CRSC code), as represented among Fig. 2.Fig. 2 is an icon of describing more specific encoder 126.At first, by the turbine code that circles round a plurality of input information bits A, B are encoded to a plurality of system bits A, B and a plurality of check digit Y1, Y2, W1, W2.Each system bits and corresponding at least some check digit.Check digit is error detection or the correction that is used for its corresponding system bits.Check digit Y1 and W1 produce by forming encoder (constituent encoder) 102, and check digit Y2 and W2 produce by turbine code interleaver that circles round (CTC interleaver) 100 and composition encoder 104.

After encoded, the miscommunication that a plurality of sub-block of bits of coded are staggeredly placed with the kind of avoiding gathering together on special channel is taken place by the passage interleaver.About Fig. 3, each sub-block of a plurality of bits, for example, A sub-block 108, B sub-block 110, Y1 sub-block 112, Y2 sub-block 114, W1 sub-block 116, W2 sub-block 118 rearrange (route) bit-order to produce an interleaved code sequence 122 by sub-block interleaver 120.

After the processing that interlocks, the action that has comprised the interleaved code sequence 122 meeting process rejectings (puncture) partly of system bits part and check digit is to meet rate matchers 130 desirable code rates.After the action of rejecting, accord with first corresponder 132 bits of coded is tuned as a plurality of symbol units (complex-valued symbol), the first symbol unit that is of wherein a plurality of symbols with real part and imaginary part.By code word crossfire corresponder 134 is exchanged sign-alternating unit and be converted to multiple transmission stream by a unique sequence.For example, use one based on the code word of data circulation modes of emplacement to crossfire corresponder (circulation-based CW-to-stream mapper).Then, in precoder 136, crossfire is carried out precoding, and send out by a plurality of antennas according to (pre-designed) pre-coding matrix that designs in advance.Fig. 4 a, Fig. 4 b and Fig. 4 c show that code word respectively is converted to the symbol metasequence of a single coding, modulation the icon of 2,3 and 4 crossfires to crossfire corresponder 134.The quantity and the pre-coding matrix of above-mentioned code rate, modulation stratum, data transmission crossfire are all adjusted by controller 138, in order to revise the transmission of combinations thereof.

Fig. 5 a is the example that shows the Data Processing of exporting based on the spatial multiplexing multi-input multi of single codeword, wherein the quantity N of information bit _EpBe 48, and adopt 16 orthogonal amplitude modulating and changings (16-QAM), code check R is 2/3, and the quantity L of crossfire is 2.In this example, at first utilize the turbine code that circles round of 1/3 code check that information bit is encoded, then, through the program of Bit Interleave and rejecting to meet 2/3 code check.Therefore, 48 system bits and have been comprised in the coding sequence through last 24 bits of coded of being used as check digit after the action of rejecting.Check digit continues after system bits in coding sequence.Through after the rejecting program, bits of coded is corresponded to Fu Yuanzhong by according with first corresponder 132.Owing to be to utilize 16 orthogonal amplitude modulating and changing mechanism, correspond to a plurality of modulations and accord with in the unit so per four bits of coded are divided into a group.

Every symbol unit has the bit position that association is, wherein some bit position has the bit position of higher signal priority valve (for example: sign bit (sign bit)), some bit position has than the bit position of low signal priority valve (for example: is-not symbol position (non-sign bit)).Have the position of bottom line promptly to represent a first sign bit of a plurality of modulation symbols among Fig. 5 a, and the sign bit of a plurality of modulation symbol unit is real number (real value) and the imaginary number (image value) that is used for representing more than one modulation symbol unit.Because the structure of symbol unit, sign bit has higher signal priority valve than is-not symbol position.Generally speaking, more than one modulation symbol unit is made of a plurality of bits of coded.For example, two bits constitute that a quadrature phase key moves (QPSK) Fu Yuan, four bits constitute one 16 orthogonal amplitude modulating and changings (16-QAM) symbol unit and six bits constitute one 64 orthogonal amplitude modulating and changings (64-QAM) Fu Yuan.Real number (for example, homophase) part and imaginary number (for example, the quadrature) part of wherein two bits in the symbol unit, that is sign bit arbitrarily in order to represent an orthogonal amplitude modulating and changing (QAM) Fu Yuan.Fig. 5 b and Fig. 5 c are the planispheres that shows the coding of 16 orthogonal amplitude modulating and changings, and wherein first bit and the 3rd bit are represented the symbol of real part and imaginary part respectively.As shown in Fig. 5 b and Fig. 5 c, change first bit and promptly represent certain different half one in the planisphere respectively with the 3rd bit, (that is first bit is that 1 o'clock symbol unit all occurs in the left side in the planisphere, first bit is that 0 o'clock symbol unit all occurs in the right-hand part in the planisphere; And the 3rd bit be that 0 o'clock symbol unit all occurs in the first half in the planisphere, the 3rd bit is that 1 o'clock symbol unit then all occurs in the Lower Half in the planisphere).During the Fu Yuan transmission, transmit bit and can be arranged in identical half one or the quadrant of separating the modulation zone usually.Hence one can see that, and the bit compared to being not half one of definition or a quadrant determines the bit of half one or quadrant to have low relatively error rate.Therefore, these bits have the higher signal priority valve, and are to be prior bit in transmission.Based on this specific character, because of considering of reliability, the bits of coded of outbalance (for example system bits) will be dispensed to more than one the symbol bit position in the modulation symbol unit.

Reuse the example identical, 72 whole bits of coded are corresponded to 18 16 orthogonal amplitude modulating and changings (16-QAM) Fu Yuan with Fig. 5 a.Shown according to example, can understand some system bits and be assigned to the first is-not symbol position of a plurality of modulation symbols.At last, code word is dispensed to above-mentioned 18 orthogonal amplitude modulating and changings symbol unit in two transmission streams fifty-fifty to crossfire corresponder 134, and via the channel transfer of two reality.As the direction of arrow of Fig. 5 a, system bits and corresponding check bit are dispensed in the identical passage.Based on above-mentioned discussion, suppose that wherein a passage has better and more reliable transmission quality than another passage.Yet according to this example icon, passage will present same treatment to bit configuration.In this example, because code check R is 2/3 relation, some system bits will be disposed in more insecure passage.

Fig. 6 is presented under (precoding) structure that has precoding, based on the calcspar of the transmission end of the spatial multiplexing multi-input multi output (MCW-based spatial multiplexing MIMO) of many code words.The transmission end comprises a cutter (splitter) 140, one encoders 142, one passage interleavers 144, one rate matchers, 146, one modulators, 148, one code words are to crossfire corresponder 150, with a precoder 152 of a plurality of antenna ports bindings, and a controller 154.At based on many codeword structures, controller 154 is adjusted a plurality of modulations and encoding mechanism according to the passage situation.Compare with single codeword structure described above, improve link usefulness (link performance) to provide because the variation of passage must be adjusted more parameter.Yet the quantity increase that can change parameter can cause the increase in demand of feedback signal amount.Therefore, the Data Processing mode of many codeword structures is similar to the single codeword structure basically, and only many codeword structures are based on a plurality of code words and handle simultaneously.Fig. 7 a and Fig. 7 b are the schematic diagrames that shows how code word operates crossfire corresponder 150 and precoder 152.Just in this point, how Fig. 7 a and Fig. 7 b explanation code word accords with the situation that metasequences respectively are converted to 3 or 4 crossfires with two coding modulations to crossfire corresponder 150.

Fig. 8 shows according to the described single codeword structure of an embodiment.The structure of Fig. 8 has shown that carrying out the data branch based on signal priority valve and reliability is equipped with the system block diagrams of improving employed sample method of transmission quality and/or example device.When Fig. 8 describes out relevant single codeword and explains, be familiar with the embodiment that this skill personage can understand the many codeword structures of application in the same manner.Encoder 126, passage interleaver 128, rate matchers 156, code word accord with first corresponder 160 to crossfire corresponder 158, precoder 136 and controller 162 can hardware or at least one hardware unit of realizing of software mode (for example: integrated circuit).

About Fig. 8, encoder 126, passage interleaver 128 and precoder 136 methods as described above are operated.Yet according to some embodiment, after cross-program, bits of coded will be carried out the encoding rate rate-matched based on encoding rate and the signal priority valve expected by rate matchers 156.Thus, according to different embodiment, rate matchers 156 can be according to rejecting ratio (puncturing ratio) or rejecting rule by rejecting some check digit in the coded sequence, and its middle controller 162 can decide the rejecting rate or reject rule according to channel reliability and/or position configuration.Reject ratio be meant-be arranged in than relevant check digit of the system bits of the crossfire of high-reliability passage pair and the ratio that is arranged in the check digit relevant than the system bits of the crossfire that hangs down the reliability passage.According to different embodiment, expect that the check digit relevant with the system bits of the crossfire that is arranged in low reliability passage quantitatively need be than rejecting the ratio design under the criterion more with being arranged in the check digit relevant than the system bits of the crossfire of the passage of high-reliability.For example, 2: 1 rejecting ratio is meant, compared to the relevant check digit of system bits of hanging down in the reliability passage, than the check digit that has its twice quantity compared to the check digit relevant than the system bits in the high-reliability passage.

The code word that can be considered a bit corresponder is to crossfire corresponder 158 and accord with first corresponder 160, can come distribution system position and check digit to different crossfires according to the reliability of passage.Just in this point, through the bits of coded after the cross-program at first is to carry out the rejecting program and correspond in the crossfire according to the signal reliability, then, accord with first corresponder 160 and according to signal priority valve and reliability a plurality of bits in each crossfire are corresponded to modulation symbol unit again.Therefore, with code word crossfire corresponder 134 is compared, code word is to carry out the crossfire correspondence with bit-wise to crossfire corresponder 158, rather than carries out to accord with first mode.

According to different embodiment, can carry out symbol unit correspondence more to improve the transmission link quality based on the priority valve of modulation symbol unit.In addition, according to different embodiment, can carry out based on the symbol unit of priority valve corresponding (Symbol Mapping based Priority is called for short SMP).According to the symbol of priority valve unit corresponding (SMP), system bits (for example: part and parcel in the coded sequence) be assigned to have high signal priority valve in more than one the modulation symbol unit the bit position (for example: sign bit).In addition, according to different embodiment, come the distribution system position to crossfire than the high-reliability passage based on back information from receiving terminal or other network entity.Compared to check digit, because system bits is to be the information bit that is transmitted, system bits is outbalance in coding sequence.In the time can obtaining signal in each passage in the transmission end and transmit reliability, the distribution system position can provide the transmission link quality of an improvement to passage reliably.Therefore, according to different embodiment, dispose most system bits as best one can to passage than high-reliability.Yet based on code check, system bits also might be configured in the low reliability passage.

Give controller 162 by feedback signal, make be used to refer to what person's passage comparatively reliably information may cause increasing the feedback signal amount.Yet according to other embodiment, the feedback signal amount can be by limit to the bit number that only need have the passage of best reliability.According to other embodiment, the feedback signal amount of 1 to 3 bit is promptly enough.In some embodiments, for example correspond to the multi-input multi output system of two data streams of passage separately respectively, need 1 bit signal amount of feedback (a one-bit overhead) to give a transmission end in the multi-input multi output system of an open loop (open-loop) to point out the quality of passage.If under the situation of using Ns transmission stream, then need the bit usefulness of the quantity of log2NS to carry out in the circular of channel reliability.In some closed circulation (closed loop) system, can effectively obtain the information of channel reliability in the transmission end, so do not need extra feedback signal.Therefore, put the spectrum efficiency that distributions (jointallocation) improves link reliability and increase integral body according to come the allocation bit position can therefore be used to develop a cover associating bit in conjunction with channel reliability and signal priority valve.

According to described above, Fig. 9, Figure 11, Figure 13 and Figure 15 are the bit position allocation result that shows a plurality of embodiment.Though it should be noted that Fig. 9, Figure 11, Figure 13 and Figure 15 all relevant for the system of two effective passages, above-mentioned shown technology and embodiment can be applicable to use in the system of any number of channels.Fig. 9 show to utilize in conjunction with based on the symbol unit rule of correspondence of signal priority valve and code word based on signal/channel reliability the crossfire rule of correspondence being decided the bit position.As described in Figure 9, the quantity of signal data is 48, and the use code check is 2/3 16 orthogonal amplitude modulating and changings, and produces two groups of data streams on the passage of each transmission.By the feedback signal that for example controller 162 is received, decide the reliability degree of this two passage.

As described in Figure 9, after coding, staggered and rejecting program, produce the system bits of coding and the sequence of check digit.The bits of coded that these produced then disposes its placement location by the code word based on the signal reliability to the crossfire corresponder.So, system bits can correspond to the crossfire in the more reliable passage, and other remaining system bits then is placed in the passage of low reliability, and all check digit all are routed in the crossfire of passage of low reliability.Then, carry out symbol unit correspondence according to corresponding (SMP) rule of symbol unit of priority valve.The system bits that is arranged in the crossfire of low reliability passage is assigned to a plurality of bit positions that accord with the higher signal priority valve of unit (complex-valued symbols) the inside of the crossfire of the passage that hangs down reliability that is symbol bit position.Check digit then is configured to the bit position of signal priority valve lower in the crossfire of low reliability passage, that is on the is-not symbol bit position.Therefore, first crossfire that such operation has produced the inside in than the high-reliability passage is all system bits, and higher signal priority valve bit position is all system bits in second crossfire in low reliability passage, and any remaining higher signal priority valve bit position and be all check digit than low signal priority valve bit position in second crossfire in low reliability passage.

Figure 10 is the flow chart that shows the demonstration methods of the bit configuration that will finish Fig. 9.The demonstration methods of Figure 10 comprises the bits of encoded coding that a plurality of passages by a multiplexor communication system will transmit, and wherein bits of encoded is the bits of coded (in step 400) with system bits and check digit.A plurality of passages of multiplexor communication system comprise the passage and the passage with low reliability that have than high-reliability.In step 410, this demonstration methods comprises several system bits at least is configured to than the bit position in first crossfire in the passage of high-reliability.According to other embodiment, all bit positions in first crossfire are all the distribution system position.In step 420, demonstration methods comprise configuration at least several remaining system bits to second crossfire of the passage of low reliability, have on the bit position of higher signal priority valve.According to other embodiment, some or or even whole second crossfire in the bit position of higher signal priority valve all be assigned to system bits.In step 430, demonstration methods also comprises and is left available bit position in some or whole at least check digit to the second crossfire of distribution.In some embodiments, distribute some or whole at least check digit to comprise that the check digit that some is relevant with the system bits that is arranged in first crossfire is dispensed to the bit position of second crossfire.

Figure 11 is the method that shows according to the described another kind of bit configuration of an embodiment.Figure 11 be to use in conjunction with the rejecting program and based on the code word of signal/channel reliability to the crossfire rule of correspondence and the bit configuration that decides based on the symbol rule of correspondence of signal priority valve.Example described in Figure 11, the quantity of signal data are 48, and the use code check is 2/3 16 orthogonal amplitude modulating and changings, and respectively produce one group of data stream on passage of each each transmission.And judge wherein which passage has better reliability degree compared with another passage.

As described in Figure 11, after coding and cross-program, produce the system bits of coding and the sequence of check digit.The bits of coded that these produced is then come corresponding its position to the crossfire corresponder according to the signal reliability by code word.So, system bits can correspond in the crossfire than the high-reliability passage.Any remaining system bits then is placed in the low reliability passage, and all check digit all are routed in the crossfire of low reliability passage.

Reject a little unwanted bits of coded sequence according to rejecting ratio.So, after system bits has been filled up bit position than the high-reliability passage, determine which system bits still to be assigned in the low reliability passage.Rejecting the decision of ratio, is to wish after the rejecting program, be configured in low reliability passage in the relevant verification potential energy of system bits than with next many of the number of the check digit relevant than system bits in the high-reliability passage.As described in Figure 11, reject, in some embodiments, after the rejecting program, carry out code word to the crossfire correspondence according to reliability again than being 1: 2.

Corresponding according to carry out symbol unit based on corresponding (SMP) rule of symbol unit of priority valve.So, the system bits that is arranged in the crossfire of low reliability passage will be assigned on the bit position of the higher signal priority valve that accords with the unit the inside, that is on the sign bit position, and check digit then is configured on the lower signal priority valve bit position of symbol unit the inside in the crossfire of low reliability passage, that is on the is-not symbol bit position.Therefore, such operation can cause being all system bits and second crossfire in low reliability passage than first crossfire in the high-reliability passage and has in high signal priority valve bit position and also be system bits.Check digit then is assigned to the Fu Yuanzhong that has the configuration-system position in second crossfire bit position than the low signal priority valve, and remaining check digit will be assigned in second crossfire in any remaining available bit positions.

Figure 12 is the flow chart that shows for the demonstration methods of finishing the described bit configuration of Figure 11.The demonstration methods of Figure 12 comprises that the bits of encoded that a plurality of passages by a multiplexor communication system will transmit is a bits of coded, and wherein bits of coded has system bits and check digit (in step 500).A plurality of passages of multiplexor communication system comprise having one than the passage of high-reliability and the passage of low reliability.In step 510, reject unwanted bits of coded according to rejecting ratio.The decision of above-mentioned rejecting ratio, be wish to stay more be configured in second crossfire in the relevant check digit of system bits.According to some embodiment, before the configuration bit position, carry out the rejecting program earlier.In step 520, demonstration methods comprise distribution at least several system bits to corresponding to than on the bit position in first crossfire of high-reliability passage.According to other embodiment, all bit positions in first crossfire all are configured to system bits.In step 530, demonstration methods comprise distribution at least several remaining system bits to second crossfire, have on the bit position of higher signal priority valve corresponding to the passage of low reliability.In step 540, demonstration methods also comprises at least some the passed through rejecting program remaining check digit relevant with the system bits that is arranged in the second crossfire bit position, and at least some check digit of having passed through rejecting program relevant with the system bits of the bit position that is arranged in first crossfire, be dispensed in second crossfire remaining than in the low signal priority valve bit position.
