Description
Technical field
The present invention relates in mobile radio system data sequence and control sequence is multiplexing and the sequence after multiplexing is mapped to the method for physical channel.
Background technology
The data sequence and the control sequence that are sent to physical layer from medium access control (MAC) layer are encoded, and provide transmission and control business by wireless transmission link then.The combination that channel coding schemes comprises error detection, error correction, rate-matched, interweave and transmitting channel information or control information are mapped to the processing of physical channel.According to encoding scheme, the data that send from the MAC layer comprise systematization bit (systematic bit) and nonsystematic bit (non-systematic bit).The nonsystematic bit can be a Parity Check Bits.
In third generation partner program (3GPP), Uplink Shared Channel of uplink transport channel (UL-SCH) and Random Access Channel (RACH) can be mapped to the Physical Uplink Shared Channel (PUSCH) and the Packet Random Access Channel (PRACH) of physical channel respectively.Ascending control information (UCI) is a kind of ascending control channel information, and it can be mapped to Physical Uplink Control Channel (PUCCH) and/or PUSCH.The DSCH Downlink Shared Channel of descending transmission channel (DL-SCH), broadcast channel (BCH), paging channel (PCH) and Multicast Channel (MCH) are mapped to Physical Downlink Shared Channel (PDSCH), Physical Broadcast Channel (PBCH), Physical Downlink Shared Channel (PDSCH) and the Physical Multicast Channel (PMCH) of physical channel respectively.The control format designator (CFI) of down control channel information, mix physical control format indicator channel (PCFICH), physics HARQ indicator channel (PHICH) and Physical Downlink Control Channel (PDCCH) that automatic repeat requests (HARQ) designator (HI) and descending channel information (DCI) are mapped to physical channel respectively.Above-mentioned transmission channel is mapped to each physical channel by multiple processing.Especially, in channel, carry out the processing of Cyclic Redundancy Check, code block segmentation, chnnel coding, rate-matched and code block cascade at least one transmission channel or control information such as UL-SCH.
Fig. 1 illustration be used to handle the processing of transmission channel and/or control information.The data of input transmission block form in each Transmission Time Interval (TTI).Transmission block is carried out following processing.The CRC extra block is to the data affix CRC of transmission block form.The data sementation that the code block segmentation piece will add CRC becomes one or more code block.The code block data flow of the code block of channel coding blocks after to each segmentation is carried out chnnel coding.The data flow of rate matching block after to chnnel coding carried out rate-matched.The data flow cascade of code block cascade piece after with one or more rate-matched is to form the sequence of data bits behind the coding.Simultaneously, independent channel coding blocks is carried out chnnel coding to form the control bit sequence after encoding to control information.The sequence of the data bit of multiplexing of data/control after to coding and the control bit sequence behind the coding are carried out multiplexing, generate the bit sequence after multiplexing thus.
According to order of modulation (Qm), a symbol can comprise at least one bit.For example, for BPSK, QPSK, 16QAM and 64QAM, corresponding with it respectively a bit, two bits, four bits and six bits have constituted a symbol.In the system that uses single-carrier frequency division multiple access (SC-FDMA), a symbol is mapped to a resource particle (RE), and therefore, can be that unit describes with the symbol.Therefore, consider order of modulation, for convenience of description, term " data bit behind the coding ", " control bit behind the coding " and " bit after multiplexing " can replace with term " data symbol behind the coding ", " control character behind the coding " and " multiplexed symbols " respectively.For convenience of explanation, term " data bit behind the coding ", " data symbol behind the coding ", " data symbol behind the coding ", " control bit behind the coding " and " control character behind the coding " can abbreviate " data bit ", " data symbol ", " control bit " and " control character " respectively as.
According to the control information characteristic, this control information can be divided into one or more types, and can consider multiple multiplexing scheme according to the quantity of type.
If there is a kind of control information, when with data message and control information when multiplexing, control information might or may not can rewrite (overwrite) data message.
If there are two kinds of control informations, control information is divided into the control information of the first kind and the control information of second type.If the control information of second type is more important than the control information of the first kind, then rewrite or the mode of overwriting data information is not multiplexing with data message and control information according to the control information of the first kind.Then, the control information of second type may or may not rewrite data message and/or the first kind control information after multiplexing.
Among Fig. 2 illustration handle the processing of transmission channel of the UL-SCH of 3GPP.Fig. 2 illustration " R " OK * " C " is listed as (R*C) (for example, matrix structure C=14).Below, this structure can be called " resource particle set ".In C the continuous symbol arrangement time domain in the horizontal direction, and R virtual subnet carrier wave is arranged in the frequency domain of vertical direction.In the resource particle set, the arrangement adjacent one another are of virtual subnet carrier wave, but the subcarrier on each physical channel corresponding with the virtual subnet carrier wave can be discontinuous in frequency domain.The back, for simplicity, the term " virtual subnet carrier wave " that will be associated with the resource particle set is called " subcarrier ".In common circulating prefix structure (" common CP structure "), the individual symbol of 14 (C=14) constitutes a subframe.In expansion CP structure, the individual symbol of 12 (C=12) can constitute a subframe.That is to say that Fig. 2 is based on the structure of common CP.If use " structure of expansion CP ", it is 12 matrix structure that Fig. 2 can have C.With reference to Fig. 2, M the symbol (symbolic number * sub-carrier number of=each subframe=C * R) mapped.That is to say that M symbol can be mapped in M the resource particle of each subframe.Except passing through the symbol with data symbol and the multiplexing generation of control character, reference signal (RS) symbol and/or detection RS (SRS) symbol can be mapped to M resource particle.Therefore, if K RS symbol and/or SRS symbol are shone upon, then can shine upon (M-K) individual multiplexing symbol.
Fig. 2 shows the example that two types control information (that is, control information 1 and control information 2) is mapped to the resource particle set.With reference to Fig. 2, shine upon multiplexing symbol sebolic addressing according to the method for time priority mapping.That is to say, begin to shine upon in order symbol sebolic addressing after multiplexing to the right from first character position of first subcarrier.If mapping finishes in a subcarrier, then first character position from next subcarrier begins to shine upon in order to the right.Back, symbol can be the SC-FDMA symbols.Can shine upon control information 1 and data message according to the order of control information 1 → data message by the method for time priority mapping.Order according to end subcarrier → first subcarrier is mapped to 2 of control informations on the symbol that is positioned at RS symbol both sides.The end subcarrier is meant the subcarrier of the resource particle set bottom that is positioned at Fig. 2, and first subcarrier is meant the subcarrier at the top that is positioned at the resource particle set.Control information 1 is carried out rate-matched and mapped with data message.Control information 1 after 2 pairs of data messages of control information and/or the mapping is punched and is mapped.Can form data message from a plurality of code blocks that a transmission block segmentation obtains by cascade sequentially.
When multiplex data information and control information, should consider following situation.
At first, multiplexing criterion not should along with the existence of the quantity of control information and type or control information whether and change.The second, when the control information of data and/or other type was punched in control information through-rate coupling and data multiplex or control information, control information should not influence the transmission of other data of circular buffer.The 3rd, the starting point of the circular buffer of next redundancy versions is not answered the existence whether influence of controlled information.The 4th, in mixing automatic repeat requests (HARQ) transmission plan, should avoid the conflict of HARQ buffer.With multiplexing information mapping in the method for data channel, the control information of particular type should be mapped in the resource particle adjacent with having the RS of good capacity.
In the method for Fig. 2,, need a kind of new criterion to shine upon the control information of other type because two types control information has been mapped in the physical vlan channel with data message.In the method for Fig. 2, when data message and/or control information 1 punching is fallen in control information 2, begin to carry out punching from the code block at end.But, if because transmission environment and bit rate and to produce wrong probability in the code block of end higher, then mistake will only appear at the end code block.Under the sort of situation, after whole code blocks are decoded, carry out error detection, then error of transmission determine existing delay, and the power that the code-aiming block decoding is consumed increases.

Embodiment
Describe preferred implementation of the present invention in detail now with reference to accompanying drawing.Specifying of providing with reference to the accompanying drawings is intended to explain illustrative embodiments of the present invention, rather than the unique execution mode that can realize according to the present invention is shown.Below specify and comprise that detail is to provide thorough understanding of the present invention.But, it will be understood by those skilled in the art that and can not adopt these details to realize the present invention.For example, provided following specification around specific term, but the invention is not restricted to this, other term also can be used to express the identical meaning.Present disclosure adopts identical reference symbol to refer to identical or similar part in the whole text.
In reality was implemented, each unit in the block diagram can be divided into two hardware chips or two or more unit can be integrated in the hardware chip.
Following illustrative embodiments is used to handle the transmission channel (especially UL-SCH) of 3GPP.
According to arbitrary method or its " importance ", control information can be divided into all kinds.Here, " importance " can be when being evaluated at the control information bust this of any kind, and the influence degree of the ability of mobile radio system is determined.When having polytype control information, need new multiplexing scheme to improve the ability of mobile radio system.For example, can be with multiplexing so that should do not rewritten than the control information of important type by the control information of more unessential type than the control information of important type.
In the present invention, control information 1 can be channel quality information (CQI)/pre-coding matrix index (PMI), and this control information is the combination of the PMI of the CQI of indication channel quality and the index information of indicating the code book that is used for precoding.Control information 1 can be multiplexing to carry out with the data message rate-matched.Control information 2 can be the ack/nack (ACK/NACK) as the HARQ response.Can punch data message or control information 1 of control information 2 is multiplexing to be used for.Control information 3 can be the order indication or the order information (RI) of the quantity of expression transport stream.Control information 3 can punch data message or control information 1 or multiplexing to be used for data message and/or control information 1 rate-matched.
Can revise the illustrative embodiments that proposes by the present invention structure and with its be applied as by resource grains molecular resource particle in conjunction with in respect to frequency axis and time shaft up and down or symmetrical structure.In an exemplary embodiment of the present invention embodiment, symbol can be the SC-FDMA symbol.
Term " punching " is meant that removing specific bit (or symbol) from the sequence of being made up of a plurality of bits (or symbol) also inserts new bit (or symbol) in this sequence.That is to say that punching utilizes out of Memory to replace the part of information, and when with data message or control information when multiplexing, bit (or symbol) information that is perforated of the information fallen of punching replaces.When adopting the punching scheme,, also keep the length of whole bit (or symbol) even after having inserted new information.The influence that the bit rate of the information after the punching is punched.
Term " rate-matched " is meant the bit rate of adjusting data message.When data message or control information were re-used, the position of each information can change but the content of information is unaffected.The quantity of the control information of the rate-matched that " rate-matched " expression of control information 1 and data message increases and the data message of rate-matched has predetermined size.Therefore, if the quantity of control information to be sent 1 increases, then carry out the corresponding amount of quantity minimizing of the data message of rate-matched with this control information 1.
Transmit if transmission block is segmented into a plurality of code blocks, then receiver side can since the 0th code block sequentially code-aiming block decode.At this moment, punch if utilize control information to begin code-aiming block from last code block of data message, then because transmission environment and bit rate, mistake only appears at the end code block.Then, sizable power takes place to postpone and consume in error detection when code-aiming block is decoded.If exist punching to fall the control information of data, then because the past code block begins the execution punching, so early stage stopping is feasible in decoding processing.
The a plurality of code blocks that generate from a plurality of code blocks of the code block segmentation piece of Fig. 1 can be of different sizes.At this moment, the size of preceding code block is littler than the size of back code block.At this moment, each code block can carry out rate-matched in the rate matching block of Fig. 1, makes the code block of different size have identical size.Then, the bit rate than short preceding code block is lower than the bit rate of long back code block than length relatively for length.Therefore, when code block was perforated control information, preceding code block was littler than the influence that back code block is subjected to.
In the illustrative embodiments of Fig. 7 to Figure 12, when data message is perforated control information (for example, control information 2), data message is punched since first code block.Then, the first code block place produces wrong probability increases relatively.If the first code block place makes a mistake,, thereby can reduce the power that code-aiming block is decoded and consumed then owing to can pre-determine error of transmission whether occurs.Compare with conventional method, punching is fallen the influence that data message brought and is reduced relatively.
Fig. 3 a to Fig. 6 is the figure that is used to define the term of the illustrative embodiments that is commonly used to key diagram 7 to Figure 13 in this application.
Fig. 3 a is based on the configuration of common CP to resource particle shown in Figure 13 set, and hypothesis has been constructed M (the individual resource particle of=R * C).Here, " C " is illustrated in the quantity of " symbol period (the symbol period) " that arrange on the time orientation, and " R " is illustrated in the quantity of the subcarrier of arranging on the virtual frequency direction.Symbol period is meant the time period that a symbol exists.Therefore, the length of the length of a symbol period and a symbol is identical.
For the following description, the subcarrier that will be arranged in first row that the whole zone of resource particle set begins from the top is defined as " subcarrier 0 ", and the subcarrier that will be positioned at the end row is defined as " subcarrier R-1 ".That is to say that first subcarrier in transmission band is defined as " subcarrier 0 ", and next subcarrier is defined as " subcarrier 1 ", " subcarrier 2 " etc. successively.Last subcarrier is defined as " subcarrier R-1 ".
Fig. 3 a, 3b, 4a and 4b illustration be used to explain the notion of illustrative embodiments of the present invention.In following explanation, term " first subcarrier " and " end subcarrier " can use explicitly with specific time-frequency region (zone " A ").Zone A can be the part of resource particle set or the whole set of resource particle.Zone A represents that any zone and each resource particle among the regional A of resource particle set can be in time domain or frequency domain discrete each other (illustrated as Fig. 4 b)." first subcarrier " of zone A is illustrated in the subcarrier of row at the top of regional A, and last subcarrier of regional A is illustrated in the subcarrier of row of the bottom of regional A." first resource particle " (" F ") and " end resource particle (" L ") and the regional A use that combines.That is to say, be positioned at resource particle foremost in first subcarrier of the regional A of " first resource particle " expression of regional A in time, that is to say the resource particle of left column.Be positioned at the resource particle of rearmost end in the end subcarrier of the regional A of " end resource particle " expression in time.That is to say the resource particle of right column.A first interior resource particle of subcarrier represents that subcarrier is positioned at resource particle foremost on the inherent time.The end resource particle is meant the resource particle that is positioned at rearmost end in this subcarrier on the time.
With reference to Fig. 5 a, RS is mapped to " RS symbol period " (it comprises " RS symbol period (0) and " RS symbol period (1))." RS symbol period (0) and " RS symbol period (1) can be not adjacent to each other.
To " the RS symbol period zone " of definition in " RS symbol period " be introduced.RS symbol period zone comprises (2xR) resource particle that is positioned at the RS symbol period." RS symbol period zone " is divided into " RS symbol period zone (0) and RS symbol period zone (1) ".Each of RS symbol period zone (0) and RS symbol period zone (1) has R resource particle on frequency domain direction.
With reference to Fig. 5 b, " first symbol period " is defined as and departs from 4 symbol periods that the RS symbol period is 0 symbol period." the first symbol period zone " comprises (4xR) the individual resource particle that is positioned at first symbol period.Therefore, at Fig. 3 a to 6b, " first symbol period " also is divided into " the first symbol period zone (0) ", " the first symbol period zone (1) ", " the first symbol period zone (2) " and " the first symbol period zone (3) ".
With reference to Fig. 5 c, " second symbol period " is defined as and departs from 4 symbol periods that the RS symbol period is 1 symbol period." the second symbol period zone " comprises (4xR) the individual resource particle that is positioned at second symbol period.Therefore, at Fig. 3 a to 6b, " the second symbol period zone " also is divided into " the second symbol period zone (0) ", " the second symbol period zone (1) ", " the second symbol period zone (2) " and " the second symbol period zone (3) ".

Because the structure of Figure 13 and the symmetrical configuration of Figure 12, the method among Figure 13 is identical with the described characteristic of Figure 12.Below, in the method for Figure 12 or Figure 13, specify the position of control information 3 with reference to table 1 to table 9.
To the table 9, specifically introduce earlier the execution mode of above-mentioned Fig. 7 to 13 at instruction card 1.Control information 1 can be multiplexing with data message before being mapped to the resource particle set.That is to say, control information 1 and data message is multiplexing to generate the stream after multiplexing, make data message be arranged in after the control information 1.Then, begin or begin to shine upon this stream after multiplexing from the end resource particle in the whole zone shown in each figure to the mapping order from first resource particle in the whole zone shown in each figure according to forward direction mapping order according to the back.Utilize this method, control information 1 can be mapped in the whole zone of resource particle set except branch is used in the resource particle that RS shines upon, comprise first or one or more continuous resource particle of end resource particle in.Will be appreciated that,, also can use above-mentioned execution mode even control information 1 does not exist.
In the execution mode of Fig. 8 to 13, if control information 2 does not exist, then control information 1 and control information 3 are mapped and do not have control information 2 in each figure, and if control information 3 does not exist, then control information 1 and control information 2 are mapped and do not have control information 3 in each figure.
In the method for Figure 12 or 13, the position of control information 3 (i.e. second symbol period) can be as defining to any table of table 9 in following table 1.Table 1 to table 9 is represented according to the structure of Cyclic Prefix (CP) and the structure of detection reference signal (SRS), the symbol period that control information 3 can be mapped to.Although in Figure 12 or Figure 13, as CP, same method also can be applied to expand CP with common CP.
Figure 14 a illustration has been used the structure of the illustrative embodiments of common CP, and Figure 14 b illustration has been used the structure of the illustrative embodiments of expansion CP.
Data message and control information institute mapped symbol cycle can change by the structure of CP or the structure of SRS.When adopting common CP, shown in Figure 14 a, a subframe comprises 14 symbol periods.Suppose at table 1 that to table 9 RS is arranged in the 4th (" 4. ") and the 11st of 14 symbol periods
Symbol period.When adopting expansion CP, shown in Figure 14 b, a subframe comprises 12 symbol periods.Suppose at table 1 that to table 7 RS is positioned at the 4th (" 4. ") and the 10th (" 10. ") symbol.Simultaneously, the residing symbol period of RS can be according to changing with table 1 to the different mode of table 9, and at this moment, data message can be according to changing with table 1 to the different mode of table 9 with the control information institute mapped symbol cycle.
At table 1 to table 9, the symbol period that the numeral control information 3 in " { } " of " row set " can be mapped to.These numerals can be assigned to the symbol period except that branch is used in the RS mapped symbol cycle among Figure 14 a and the 14b.Particularly, digitized representation in " { } " and the digital corresponding symbol cycle that is arranged in Figure 14 a and/or Figure 14 b bottom.In common CP, the numeral in " { } " can be 0 to 11, and in expansion CP, the numeral in " { } " can be 0 to 9.
Table 1 to table 9 comprises that SRS is mapped to first symbol period and the structure that is mapped to the end symbol period.To table 9, " a SC-FDMA symbol " expression SRS is mapped to first symbol period at table 1, and " end FDMA symbol " expression SRS is mapped to the end symbol period, and " no SRS " expression does not have SRS mapped.
[table 1]
In the table 1, in the end SC-FDMA symbol of expansion CP, can use in a plurality of row set.
[table 2]
In expansion CP, might not allow SRS to be mapped to the end symbol period, even perhaps allow SRS, SRS also might be abandoned.Then, as illustrated in the table 2, " end SC-FDMA symbol " can have the row set identical with " no SRS ".
[table 3]
" end SC-FDMA " expression of the expansion CP of table 3 is because SRS can revise the control information position in 3 mapped symbol cycles.
[table 4]
In expansion CP, might not allow SRS to be mapped to the end symbol period, even perhaps allow SRS, SRS also might be abandoned.When not allowing " end SC-FDMA symbol " SRS,, when " end SC-FDMA symbol " SRS also can be abandoned, can use the expansion CP of table 4 even perhaps allow " end SC-FDMA symbol " SRS.If do not use a SC-FDMA symbol SRS, then the expansion CP of table 4 can be configured to not have a SC-FDMA symbolic component (comprising its " row set ").
[table 5]
With reference to Figure 14 a and Figure 14 b, will be appreciated that the structure of " the row set " of table 5 is corresponding to the second symbol period zone.That is to say that control information 3 is mapped to the distance branch and is used in the symbol period of a RS mapped symbol cycle symbol period.The position of numeral " 9 " the expression SRS in expansion CP though " end SC-FDMA symbol ",, when not allowing SRS to be mapped to the end symbol period,, can use this structure when this SRS is also abandoned even perhaps allow SRS.In addition, because the position of " row set " in each CP structure is identical, so can represent table 5 with the structure that does not have SRS.
[table 6]
With reference to Figure 14 a and Figure 14 b, will be appreciated that each structure " the end SC-FDMA symbol " in expansion CP of table 6 is corresponding to the second symbol period zone.Simultaneously, will be appreciated that control information 3 is not mapped in the resource particle of first symbol period.Because SRS is mapped to the position of symbol period " 9 ", so the expansion CP of table 6 " end SC-FDMA symbol " is not mapped to symbol period " 9 ".Table 6 is compared the structure difference of " end SC-FDMA symbol " among the expansion CP with table 5.That is to say that the branch that the control character 3 that is arranged in the symbol period " 9 " of table 5 is mapped to table 6 is used in non-conterminous symbol period of RS mapped symbol cycle " 5 ".In the expansion CP of table 6, " end SC-FDMA symbol " " the row set 1; 4; 6; 5} " and expression: because symbol period " 6 " is used in the RS mapped symbol cycle than the more close branch of symbol period " 5 ",, symbol period " 6 " shines upon so having than the higher priority of symbol period " 5 ".More particularly, control information is being inserted in the processing of each symbol period symbol uniformly, if control information can only be received in one in symbol period " 5 " and " 6 ", the then symbol cycle " 6 " has precedence over symbol period " 5 ".But { 1,4,6,5} represents the row set, also can be according to { 1,4,5, the order of 6} is distributed priority in i.e. use.The position in 3 mapped symbol cycles of control information is very important.
[table 7]
With reference to Figure 14 a and Figure 14 b, will be appreciated that the structure of the expansion CP of table 7 is corresponding to the second symbol period zone.What should also be clear that is that in table 7, control information 3 is not mapped in the resource particle of first symbol period.Different with table 5 and table 6 is, no matter table 7 has identical " row set " and the structure of SRS in expansion CP.In the expansion CP of table 7, " the row set " { 1 of " end SC-FDMA symbol ", 4,6,5} represents: because symbol period " 6 " is used in the RS mapped symbol cycle than the more close branch of symbol period " 5 ", shine upon so symbol period " 6 " has than the higher priority of symbol period " 5 ".More particularly, control information is being inserted in the processing of each symbol period symbol uniformly, if control information can only be received in one in symbol period " 5 " and " 6 ", the then symbol cycle " 6 " has precedence over symbol period " 5 ".But { 1,4,6,5} represents the row set, also can be according to { 1,4,5, the order of 6} is distributed priority in i.e. use.The position in 3 mapped symbol cycles of control information is very important.Because table 7 has in each CP identical " row set " with the structure-irrelevant of SRS, so can represent table 7 without the SRS structure.
Figure 15 a and 15b illustration be used to explain the exemplary configurations of expansion CP of the structure of following table 8 and table 9.
[table 8]

Figure 16 and Figure 17 illustration under the situation of common CP and expansion CP, in a subframe, distribute the example of the position of SRS and RS respectively.
Figure 16 and Figure 17 correspond respectively to Figure 14 a and Figure 14 b, and illustration be not mapped to the situation of last symbol when SRS has mapped and SRS.Consider order of modulation, control information 3 is mapped to the distance branch and is used in the symbol period of a RS mapped symbol cycle symbol lengths.Therefore, in Figure 16, it is 1,4,7 and 10 symbol period that control information 3 is mapped to index.In Figure 17, it is 1,4,6 and 9 symbol period that control information 3 is mapped to index.
