Embodiment
For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
The flow chart of a kind of data transmission method for uplink that Fig. 1 provides for the embodiment of the present invention.As shown in Figure 1, the method for the present embodiment comprises:
Step 101, data block to be sent is divided, obtain multiple sources symbol.
Step 102, multiple sources symbol is carried out to fountain codes (Fountain) coding, export the symbol after multiple codings and send the symbol after described multiple codings to receiving terminal, in the time receiving the confirmation that receiving terminal returns, stop source symbol to carry out fountain codes (Fountain) coding, described confirmation is used for identifying described receiving terminal and has successfully received described data block to be sent.
In an optional execution mode, before step 101, comprise: for original data block adds cyclic redundancy check (CRC) (Cyclical Redundancy Check, referred to as CRC) code, obtain described data block to be sent.Optionally, the data block to be sent in step 101 can be also the original data block that does not add CRC code.
Taking data block to be sent as the data block of having added CRC code is as example, suppose that original data block is K bit, taking the CRC code that adds as R bit is as example, transmitting terminal adds the original data block of K bit the CRC code of R bit, obtains the data block to be sent of (K+R) bit.Then, transmitting terminal is divided data block to be sent, obtains multiple sources symbol, to obtain T source symbol as example.Optionally, transmitting terminal can carry out decile to data block to be sent, obtains multiple sources symbol that size is identical.For example, transmitting terminal can, according to the quantity of the transfer resource being assigned within the unit interval, carry out decile to the data block to be sent of (K+R) bit, obtains T source symbol.Unit interval in each embodiment of the present invention can be subframe or an other times unit, and the present embodiment is not construed as limiting this.Described transfer resource mainly refers to certain running time-frequency resource, and as Physical Resource Block, the transfer resource being assigned within the unit interval mainly refers to the one or more Physical Resource Block (Physical Resource Block, referred to as PRB) in a subframe.Wherein, transmitting terminal is according to the quantity of the transfer resource being assigned within the unit interval, data block to be sent to (K+R) bit is carried out decile, obtaining the dividing mode that T source symbol adopt is not specifically limited, but require symbol source symbol being carried out after the one and same coding of Fountain coding output to be divided in some transfer resources, so that transmission as far as possible.Based on this, a kind of dividing mode comprises: transmitting terminal is according to the quantity of the transfer resource being assigned within the unit interval, determine the bit number that each symbol comprises, then the bit number comprising according to each symbol of determining, data block to be sent is divided, thereby obtain T the source symbol that size is identical.Illustrate, suppose that the transfer resource that transmitting terminal is assigned within the unit interval is 4 PRB, and suppose to ensure the large correct probability of acceptance of each symbol, need to repeat to transmit 100 times to each symbol, can determine corresponding 8 bits of transfer resource in each unit interval, if on transfer resource, (being in each unit interval) symbol of transmission at every turn, a symbol need to comprise 8 bits, based on this, total bit number (K+R) that can comprise by data block to be sent is divided by 8 bits, the number of acquisition source symbol and can obtain the source symbol marking off.In the time that (K+R)/8 are aliquant, on (K+R) bit, fill (Padding) Ceil[(K+R)/8] the individual bit of * 8-(K+R).Wherein, Ceil is a function rounding up.
Obtaining after T source symbol, transmitting terminal carries out Fountain coding to T source symbol, generates the symbol X0 after coding, X1 ... Deng.Wherein, the symbol after described coding is made up of one or more bits, and a symbol of for example 64QAM is just made up of 6 bits.Simply say, Fountain coding can be exported the symbol after infinite multiple coding, and the symbol after each coding is to be added and formed by the source symbol mould 2 of certain a few input, and the symbol after the coding of any two outputs is completely independent incoherent.
After symbol after output encoder, the sign map after described coding, to transfer resource, is then sent to receiving terminal.Conventionally,, on the transfer resource being assigned within the unit interval, each (being in each unit interval) sends the symbol after a described coding to receiving terminal.Taking LTE system as example, suppose that a transfer resource unit is 4 PRB in a subframe, totally 400 available resource elements (ResourceElement, referred to as RE), with Quadrature Phase Shift Keying (Quadrature Phase Shift Keying, referred to as QPSK) modulation, can transmit altogether 400*2=800 bit, 8 bits a symbol when mapping repeat 800/8=100 time, then bit mapping to the transfer resource unit after repeating, i.e. 4 PRB in a subframe, on totally 400 RE.
Due to the Fountain coding of the transmitting terminal symbol after can the generation coding of indefinite length, transmitting terminal is only received after the confirmation (Ack) of receiving terminal feedback, just stop source symbol to carry out Fountain coding, also just mean the symbol stopping after output encoder and stop sending the symbol after described coding.Wherein, the confirmation that transmitting terminal sends is used for identifying receiving terminal and has successfully received described data block to be sent, and each confirmation is for a data block to be sent, the i.e. data block to be sent of (K+R) bit, it is right to be that receiving terminal only has (K+R) bit of monoblock data all to receive, just can feed back a confirmation, and not need to feed back not correct reception of which symbol, reduce the data volume of feedback.
For ease of understanding the process of transmitting of transmitting terminal, Fig. 2 separately provides a kind of schematic flow sheet of transmitting terminal transmission data.
For receiving terminal, the symbol that meeting receiving end/sending end sends, and the employing Fountain interpretation method corresponding with Fountain coding method, carry out decoding to the symbol receiving, until successfully receive data block to be sent.Processing procedure about receiving terminal can be referring to the description of embodiment below.
In the present embodiment, transmitting terminal matches with receiving terminal, data block to be sent is divided, obtain multiple sources symbol, multiple sources symbol is carried out to Fountain coding, export the symbol after multiple codings and send the symbol after described multiple codings to receiving terminal, in the time receiving the confirmation that receiving terminal returns, stop source symbol to carry out Fountain coding, wherein, this determines that information successfully receives data block to be sent for identifying receiving terminal.Owing to adopting Fountain coding, the symbol after the coding of output is separate, and importance is all identical, does not need pointedly some specific bit to be repeated to more times.Transmitting terminal stops output and sends the symbol after coding after the confirmation that receives receiving terminal transmission, to the Data duplication transmission after coding, is conducive to improve communication efficiency without again.
The flow chart of a kind of data receive method that Fig. 3 provides for the embodiment of the present invention.As shown in Figure 3, the method for the present embodiment comprises:
Step 301, reception are arrived the symbol of multiple receptions of receiving terminal through transmission by the symbol after multiple codings of transmitting terminal, wherein, the symbol after described multiple coding is that source symbol that transmitting terminal marks off data block to be sent carries out fountain codes (Fountain) coding and obtains.
Step 302, calculate the confidence level of the symbol of described multiple receptions.
Step 303, confidence level in the symbol of described multiple receptions is greater than to confidence level thresholding at least one symbol as at least one aiming symbol.
Step 304, described at least one aiming symbol is carried out to fountain codes (Fountain) decoding, and after decoding success, send confirmation to described transmitting terminal, described confirmation is used for identifying receiving terminal and has successfully received described data block to be sent.
In the present embodiment, transmitting terminal is divided data block to be sent, obtains multiple sources symbol, afterwards multiple sources symbol is carried out to Fountain coding, exports the symbol after multiple codings and sends the symbol after described multiple codings to receiving terminal.Send to receiving terminal the description that the process of the symbol after multiple codings can embodiment shown in Figure 1 about transmitting terminal.Owing to can having noise in transmission process, thus the symbol that receiving terminal receives comprise transmitting terminal send coding after symbol and the noise in transmission process.
Receiving terminal receives the symbol that is arrived multiple receptions of receiving terminal by the symbol after multiple codings of transmitting terminal through transmission, calculates afterwards the confidence level of described multiple symbols that receive.A kind of mode of confidence level of the symbol that calculates described multiple receptions comprises: after receiving terminal receives symbol, the symbol of each reception is carried out to hard decision, obtain each hard decision signal, this hard decision symbol is actually the symbol after the coding that receiving terminal thinks that transmitting terminal sends; Afterwards, receiving terminal is according to the amplitude of the amplitude of the signal of each reception and each hard decision signal, calculating noise energy, concrete using the difference of the amplitude of the amplitude of the symbol of each reception and each hard decision symbol as noise amplitude, then noise amplitude is carried out to square operation and obtain noise energy; And calculate the energy of each hard decision symbol according to the amplitude of each hard decision symbol, and concrete, the amplitude of each hard decision symbol is carried out to square operation and is obtained the energy of each hard decision symbol; Then according to the energy of each hard decision symbol and noise energy, obtain the signal to noise ratio corresponding to symbol of each reception, the confidence level of the symbol using the signal to noise ratio corresponding symbol of obtained each reception as each reception.Wherein, signal to noise ratio is larger, thinks that confidence level is higher.For example: the amplitude of supposing the symbol receiving is 1.4, and the amplitude of hard decision symbol is 1, and signal energy is 1 so, and noise energy is (1.4-1) * (1.4-1)=0.16, and signal to noise ratio is exactly 1/0.16.
After calculating the confidence level of symbol of each reception, according to the confidence level of the symbol of each reception, from the symbol of described multiple receptions, obtain at least one symbol that confidence level is greater than confidence level thresholding as at least one aiming symbol.The execution mode that obtains aiming symbol comprises: from the symbol of described multiple receptions, obtain E the symbol that confidence level is greater than confidence level thresholding, select M symbol of confidence level maximum as described at least one aiming symbol from E symbol.Wherein, T<M<E<N, T is the number of above-mentioned source symbol, the number of the symbol that N is described multiple receptions, and T, M, E and N are natural number.In specific implementation, receiving terminal can limit receiving symbol, aforesaid operations is carried out on limit, concrete, symbol of every reception, just calculate the confidence level of this symbol, and whether the total number of symbols that judgement receives is more than or equal to N, if the symbol receiving is more than or equal to N, from N symbol, select confidence level to be greater than E symbol of confidence level thresholding, if choose E symbol from N symbol, from a described E symbol, select M symbol of confidence level maximum, if choose M symbol, using a described M symbol as described at least one aiming symbol; If the symbol receiving is less than N, if or from N symbol, do not select E symbol, or from E symbol, do not select M symbol, continue to receive next symbol.
After obtaining described at least one aiming symbol, at least one aiming symbol is carried out to Fountain decoding.Fountain decoding is in fact to separate a matrix equation, finds that when receiving terminal matrix that at least one aiming symbol is corresponding is not when full rank, just thinks Fountain decoding failure, otherwise, think that Fountain is successfully decoded.
Optionally, if the data block that transmitting terminal sends is original data block, do not carry out the processing such as CRC code interpolation, after Fountain is successfully decoded, receiving terminal can send confirmation to transmitting terminal, has successfully received so that transmitting terminal is known receiving terminal the data block that transmitting terminal sends.
Optionally, if the data block that transmitting terminal sends is not original data block, but through adding the data blocks after treatment such as CRC code,, after Fountain is successfully decoded, the symbol that receiving terminal continues that at least one aiming symbol decoding is gone out carries out CRC check; If CRC check success, determine the data block (data block that transmitting terminal sends is above-mentioned data block to be sent) that successfully receives transmitting terminal and send here, send confirmation to transmitting terminal, successfully received so that transmitting terminal is known receiving terminal the data block that it sends.
Transmitting terminal only, after receiving the confirmation of receiving terminal feedback, just can stop source symbol to carry out Fountain coding, stops the symbol after output encoder and stops sending the symbol after described coding to receiving terminal.
Concerning receiving terminal, a kind of flow process that realizes above-mentioned steps 301-step 304 as shown in Figure 4, comprising:
The number N=0 of the symbol that step 401, receiving terminal initialization are received, and initialization confidence level is greater than the symbol numbers E=0 of confidence level thresholding.
Step 402, receiving terminal receiving end/sending end send containing noisy symbol, and calculate the confidence level of each symbol, and turn and perform step 403.
Step 403, receiving terminal judge whether the confidence level of the current symbol receiving is greater than confidence level thresholding; If judged result is yes, execution step 404; If judged result is no, execution step 405.
Step 404, the current symbol receiving of receiving terminal mark be for effectively, and the number E that confidence level is greater than the symbol of confidence level thresholding is added to 1, and perform step 406.
Step 405, the current symbol receiving of receiving terminal mark are invalid, and perform step 406.
Step 406, receiving terminal judge whether the number E that current confidence level is greater than the symbol of confidence level thresholding is greater than M; If judged result is yes, execution step 407; If judged result is no, return to execution step 402.
Step 407, receiving terminal are labeled as effective symbol from E is individual, select M symbol of confidence level maximum, and perform step 408.
Step 408, receiving terminal carry out Fountain decoding to the M a selecting symbol, and judge that whether decoding is successful; If judged result is yes, execution step 409; If judged result is no, return to execution step 402.
Step 409, receiving terminal carry out CRC check to decode results, and judge that whether CRC check is successful; If judged result is yes, execution step 410; If judged result is no, return to execution step 402.
Step 410, receiving terminal be to transmitting terminal feedback acknowledgment information, and finish the reception of the notebook data piece that transmitting terminal sends.
In the present embodiment, receiving terminal matches with transmitting terminal, and the symbol that transmitting terminal is carried out after Fountain coding carries out Fountain decoding, if successfully decoded, and CRC check success, sends confirmation to transmitting terminal, so that transmitting terminal stops coding and the transmission of this data block.Because the symbol after the coding of Fountain coding output is separate, importance is all identical, does not need pointedly some specific bit to be repeated to more times, thereby does not need to feed back not correct reception of which symbol, has reduced the data volume of feedback.Receiving terminal makes transmitting terminal can stop in time the symbol after output encoder and stops sending the symbol after coding in the feedback acknowledgment information after whole data block that successfully receives, and without the Data duplication after coding being sent, is conducive to improve communication efficiency again.
