Fig. 1 is the indicative flowchart of the method for the processing data of one embodiment of the invention.For ease of understanding, brief introduction is done to the data handling procedure of the embodiment of the present invention with reference to Fig. 1.When communication equipment is as data sender, data can be handled successively according to the flow shown in Fig. 1, finally launch data via antenna port.For example, during uplink, communication equipment is user equipment (UE)；In downlink transmission process, communication equipment is base station eNB.

At present, the channel coding method that LTE system is selected is Turbo codings.Here the embodiment of the present invention is described so that Turbo is encoded as an example, it should be understood that the embodiment of the present invention is not limited channel coding method, other channel coding methods should also fall in the protection domain of the embodiment of the present invention.In Turbo cataloged procedures, first the transmission block of input is done and split.In order to reduce storage, decoding time expense, by a data transmission block (English：Transport Block, referred to as：TB multiple code blocks (English) is cut into：Code Block, referred to as：CB).

Such as, maximum code block length is set to 6144 bits, the transmission block more than 6144 bits will be divided into multiple code blocks.Then, Turbo codings do independent process to each code block, and each code block can also calculate the CRC (English corresponding to each code block after Turbo is encoded：Cyclic Redundancy Check, referred to as：CRC) (not shown in figure 1), for receiving terminal quick detection.Above step is referred to collectively as Turbo codings.

In embodiments of the present invention, after the CRC check for completing code block, rate-matched can be done according to each code block, then cascades the bit of each code block.Then, data above is scrambled on the whole respectively, modulated.Or, after the CRC check for completing code block, the scrambling and modulation of code block are then carried out, then the symbol of each code block is cascaded.Finally, communication equipment launches the data after processing by antenna port.

Method according to embodiments of the present invention, communication equipment carries out the cascade of data block not after channel coding, but carries out the cascade of data block again after rate-matched or modulation, and then improves the degree of parallelism in data handling procedure.So, the embodiment of the present invention can reduce data processing time, and guarantee is provided for the real-time of communication system.

The embodiment of the present invention is described in detail below in conjunction with specific example.It should be noted that these examples are intended merely to help those skilled in the art to more fully understand the embodiment of the present invention, the scope for the embodiment that is not intended to limit the present invention.

Fig. 2 is the indicative flowchart of the method for the processing data of another embodiment of the present invention.Method shown in Fig. 2 is performed by the communication equipment sent as data, such as UE or eNB.

201, original data stream is divided into multiple data blocks.

For example, data are divided into multiple data blocks according to default data block size, in order to which communication equipment carries out independent processing to each data block.

202, multiple data blocks are carried out with channel coding, rate-matched, scrambling and the modulation of parallel block level, the data block after multiple modulation is obtained.

For example, communication equipment carries out parallel data processing using each data block as an independent unit respectively.Such as, channel coding, rate-matched, scrambling and modulation are carried out successively to data block.Concurrently handled with the granularity of data block in channel coding rate matching, scrambling and modulated process, that is to say, that do not interdepended between each data block in data processing.

203, cascade is done to the data block after multiple modulation and is merged, the new data stream after cascade merges is obtained.

Merge for example, the multiple data blocks obtained after being modulated in step 202 do cascade, new data stream is obtained, in order to which communication equipment is launched the new data stream by antenna port.

Based on above-mentioned technical proposal, in embodiments of the present invention, communication equipment carries out the cascade of data block not after channel coding, but carries out the cascade of data block again after modulation, and then improves the degree of parallelism in data handling procedure.So, the embodiment of the present invention can reduce data processing time, be the reality of communication system When property, which is provided, to be ensured.

Alternatively, as one embodiment, cascade is done to the data block after multiple modulation and is merged, when obtaining the new data stream after cascade merges, non-sequential cascade done to the data block after multiple modulation and is merged, obtain the new data stream after cascade merges.

Refer to data merged block it should be understood that non-sequential cascade merges not according to the order of each data block head and the tail connection.Such as, the cascade of order is merged into：First element of data block 1, second element ... of data block 1, last element of data block 1, first element ... of data block 2, last element of last data block.

Alternatively, as one embodiment, cascade is done to the data block after multiple modulation and is merged, when obtaining the new data stream after cascade merges, first the element of at least two data blocks in the data block after multiple modulation is interleaved, the new data block after multiple intertextures is obtained.Then, the order of elements of the new data block after multiple intertextures is connected, obtains new data stream.

Wherein, the interleaving mode used in cascade merging process can be pre-configured to be in sending ending equipment and receiving device side respectively.Or, sending ending equipment can notify the interleaving mode used to receiving device.It should be understood that the embodiment of the present invention is not limited this.

For example, the element of at least two data blocks in the data block of communication equipment respectively after multiple modulation, which is interleaved, generates new data block.Assuming that there is N number of data block, then M data block can be picked out at random and be interleaved, wherein M<N, and M and N is positive integer.

It is pointed out that in general, interleave depth is bigger, then transmission performance is better, but the complexity calculated is raised, it is necessary to which more data are done with calculating and processing that position is moved.Therefore M selection can depend on compromise consideration of both transmission performance and complexity.Wherein, the number of data block of the number of the new data block of generation with being interleaved is identical.For example：The element of 4 data blocks is interleaved, then the new data block of generation is also 4, and the element number of each data block does not change.

Then, the element of the new data block after multiple intertextures is linked in sequence by communication equipment, and new data stream is obtained after merging.That is, in cascade merging process, data are not done simple concatenated in order (such as by communication equipment, first symbol of data block 1, second symbol ... of data block 1, the last symbol of data block 1, first symbol ... of data block 2, the last symbol of last data block).But cascade the new data block after intertexture, to improve diversity gain.So, the embodiment of the present invention can improve diversity gain, and then further improve the radio interface rate of communication system.

Alternatively, will be many if the quantity of the data block after multiple modulation is even number as another embodiment Data block after individual modulation is matched two-by-two, and is respectively interleaved the element in two data blocks of pairing, obtains the new data block after multiple intertextures.

It should be understood that it is a pair that can arbitrarily select two data blocks to match somebody with somebody, the embodiment of the present invention is not construed as limiting to this.For example, it is assumed that data block number is N_DB, communication equipment can be by the 1st and N_DB/ 2+1 data block is put together to interweave into row element, by the 2nd and N_DB/ 2+2 data block is put together to interweave into row element ... by N_DB/ 2 data blocks and N_DBIndividual data block is put together to interweave into row element.Wherein, the element number of the new data block finally obtained keeps constant.

It should be understood that a data block can be excluded arbitrarily, it is a pair that also can arbitrarily select two data blocks to match somebody with somebody, and the embodiment of the present invention is not construed as limiting to this.Specifically, matching method can refer to the method being described above, and to avoid repeating, will not be repeated here.

Alternatively, it is used as another embodiment, the element of at least two data blocks in data block after multiple modulation is interleaved, when obtaining the new data block after multiple intertextures, the element of at least two data blocks in the data block after multiple modulation first can be subjected to serial order arrangement, obtain the first element sequence.Then, according to default rule, change element in the first element sequence and put in order, obtain second element sequence.Finally, the new data block after multiple intertextures is obtained from second element sequence successively.

Similarly, the element of the new data block after multiple intertextures is linked in sequence by communication equipment, and new data stream is obtained after merging.Data are not done simple concatenated in order by communication equipment, but the new data block after intertexture is cascaded, to improve diversity gain.So, the embodiment of the present invention can improve diversity gain, and then further improve the radio interface rate of communication system.

Alternatively, as another embodiment, the data block after to multiple modulation is done non-sequential cascade and merged, after obtaining the new data stream after cascade merges, the new data stream cascaded after merging is mapped to corresponding signal space layer by communication equipment, and launches new data stream by corresponding antenna port.

It should be understood that signal space layer is the combination of resources in time, frequency and space.Specifically, each data flow for carrying new data block is mapped in the combination of resources in corresponding time, frequency and space by communication equipment respectively, because the element in new data block has been made to interweave, therefore be mapped to equivalent to the element of original data block by scattered on multiple running time-frequency resources, and then improve the diversity gain of communication system.

Alternatively, as another embodiment, sending ending equipment can also send cascade pooling information to receiving device, and cascade pooling information includes the index of the interleaving mode used in cascade merging process.Specifically, The cascade pooling information can be carried by Downlink Control Information or other control information, and the embodiment of the present invention is not limited this.

For example, one field of increase is used for the index for indicating interleaving mode in Downlink Control Information (Downlink Control Information, DCI).As such, it is desirable in receiver equipment side and send the pre-configured interleaving mode concordance list of method, apparatus difference in advance.Receiving device can determine corresponding interleaving mode according to the index of interleaving mode from the concordance list, for processing procedures such as follow-up data demodulation.Specifically, interleaving mode can also be represented with an interleaving function p (r).

Assuming that the data block order exported after modulation is e_rk, r=0 ..., C-1, k=0 ..., E_r- 1, the data block order that cascade is exported after merging is f_k, k=0 ..., G-1.

So, it can realize that the cascade of data block merges by performing following procedure：

Perform after procedure above, the code block order of cascade merging module output is f_k=e_p(rj).Wherein, p (rj) is interleaving function.

Fig. 3 is the indicative flowchart of the method for the processing data of another embodiment of the present invention.In figure 3 with transmission block (English：Transport Block, referred to as：TB) and code block (English：Code Block, referred to as：CB it is described exemplified by).It should be understood that the embodiment of the present invention is not limited the size and title of data block.

Data are using TB as elementary cell in original data stream.According to default data block granularity, TB is first divided into code block (namely data block) CB1, CB2 ..., CBn by communication equipment.Then parallel data processing is done to each code block respectively, namely carries out Turbo codings, rate-matched, scrambling and modulation successively.Wherein, before TB is divided into CB, TB CRC check can first be carried out, not shown in Fig. 3.Similarly, each code block can also calculate the CRC corresponding to each code block after Turbo is encoded It is also not shown in verification, Fig. 3.

Then, each CB obtained after modulation symbol is done into non-sequential cascade to merge.Interweave for example, each CB after modulation is done, then the CB after intertexture is done into cascade and merge, to improve the diversity gain of communication system.Specifically, non-sequential cascade merging method is referred to the method being described above, and to avoid repeating, will not be repeated here.

Finally, the data after foregoing cascade is merged are mapped to signal space layer.Because the symbol in new data block has been made to interweave, therefore it is mapped to equivalent to the symbol of original data block by scattered on multiple running time-frequency resources, and then improves the diversity gain of communication system.Then, communication equipment launches aforementioned data by correspondingly antenna port.

Fig. 4 is the indicative flowchart of the method for the processing data of another embodiment of the present invention.Method shown in Fig. 4 is performed by the communication equipment sent as data, such as UE or eNB.

401, original data stream is divided into multiple data blocks.

402, multiple data blocks are carried out with the channel coding and rate-matched of parallel block level, the data block after multiple rate-matcheds is obtained.

For example, communication equipment carries out parallel data processing using each data block as an independent unit respectively.Such as, channel coding and rate-matched are carried out successively to data block.Parallel processing is carried out with the granularity of data block in channel coding and rate matching procedure, that is to say, that do not interdepended between each data block in data processing.

403, the element of at least two data blocks in the data block after multiple rate-matcheds is interleaved, the new data block after multiple intertextures is obtained.

404, the order of elements of the data block after multiple intertextures is connected, the data flow after cascade merges is obtained.

For example, obtained multiple data blocks are done cascade and merged after step 402 medium-rate is matched, new data stream is obtained, and exports and carries out subsequent treatment to next stage module.Specifically, the element at least two data blocks that communication equipment can be in data block respectively after multiple rate-matcheds, which is interleaved, generates new data block.Assuming that there is N number of data block, then M data block can be picked out at random and be interleaved, wherein M<N, and M and N is positive integer.

It is pointed out that in general, interleave depth is bigger, then transmission performance is better, but the complexity calculated is raised, it is necessary to which more data are done with calculating and processing that position is moved.Therefore M selection Compromise of both transmission performance and complexity can be depended on to consider.Wherein, the number of data block of the number of the new data block of generation with being interleaved is identical.For example：The element of 4 data blocks is interleaved, then the new data block of generation is also 4, and the element number of each data block does not change.

Then, the element of the new data block after multiple intertextures is linked in sequence by communication equipment, and new data stream is obtained after merging.That is, in cascade merging process, data are not done simple concatenated in order (such as by communication equipment, first symbol of data block 1, second symbol ... of data block 1, the last symbol of data block 1, first symbol ... of data block 2, the last symbol of last data block).

405, the data flow after merging to cascade is scrambled and modulated, the new data stream after being modulated.

For example, the data flow after cascade merges is scrambled and modulated on the whole, the new data stream after being modulated, in order to which communication equipment is launched the new data stream by antenna port.

Based on above-mentioned technical proposal, in embodiments of the present invention, communication equipment is not the merging that data block is done to order, but the new data block after intertexture is linked in sequence, and is merged with the non-sequential cascade for realizing data block.So, the data block that cascade merges, which is mapped to after different space layers, can more preferable diversity gain, improve the radio interface rate of communication system.

Alternatively, as another embodiment, if the quantity of the data block after multiple rate-matcheds is even number, the data block after multiple rate-matcheds is matched two-by-two, and is respectively interleaved the element in two data blocks of pairing, the new data block after multiple intertextures is obtained.

Alternatively, as another embodiment, the element of at least two data blocks in the data block after multiple rate-matcheds is interleaved, can be first by multiple speed when obtaining the new data block after multiple intertextures The element of at least two data blocks in data block after matching somebody with somebody carries out serial order arrangement, obtains the first element sequence.Then, according to default rule, change element in the first element sequence and put in order, obtain second element sequence.Finally, the new data block after multiple intertextures is obtained from second element sequence successively.

Alternatively, as another embodiment, the data flow after merging to cascade is scrambled and modulated, after the new data stream after being modulated, new data stream after modulation is mapped to corresponding signal space layer by communication equipment, and launches new data stream by corresponding antenna port.

Fig. 5 is the indicative flowchart of the method for the processing data of another embodiment of the present invention.It is described in figure 3 by taking transmission block TB and code block CB as an example.It should be understood that the embodiment of the present invention is not limited the size and title of data block.

Data are using TB as elementary cell in original data stream.According to default data block granularity, TB is first divided into code block (namely data block) CB1, CB2 ..., CBn by communication equipment.Then parallel data processing is done to each code block respectively, namely carries out Turbo codings and rate-matched successively.Wherein, before TB is divided into CB, TB CRC check can first be carried out, not shown in Fig. 3.Similarly, each code block can also calculate also not shown in the CRC check corresponding to each code block, Fig. 3 after Turbo is encoded.

Then, each CB obtained after rate-matched bit is done into non-sequential cascade to merge.Interweave for example, each CB after rate-matched is done, then the CB after intertexture is done into cascade and merge, to improve the diversity gain of communication system.Specifically, the method that non-sequential cascade merges is referred to the method being described above, and to avoid repeating, will not be repeated here.

Then, the data flow obtained after cascade merges is scrambled and modulated on the whole.And the new data stream obtained after modulation is mapped to signal space layer.Because the symbol in new data block has been made to interweave, therefore it is mapped to equivalent to the symbol of original data block by scattered on multiple running time-frequency resources, and then improves the diversity gain of communication system.Last communication equipment launches aforementioned data by correspondingly antenna port.

Fig. 6 is the schematic block diagram of the communication equipment of one embodiment of the invention.As shown in fig. 6, communication equipment 60 includes cutting unit 601, processing unit 602 and concatenation unit 603.

Cutting unit 601, for original data stream to be divided into multiple data blocks.

Processing unit 602, channel coding, rate-matched, scrambling and modulation for multiple data blocks to be carried out with parallel block level, obtains the data block after multiple modulation.

For example, processing unit 602 carries out parallel data processing using each data block as an independent unit respectively.Such as, channel coding, rate-matched, scrambling and modulation are carried out successively to data block.Concurrently handled with the granularity of data block in channel coding rate matching, scrambling and modulated process, that is to say, that do not interdepended between each data block in data processing.

Concatenation unit 603, the cascade non-sequential for being done to the data block after multiple modulation merges, and obtains the new data stream after cascade merges.

Merge for example, the multiple data blocks obtained after processing unit 602 is modulated do cascade, new data stream is obtained, in order to which communication equipment is launched the new data stream by antenna port.

Based on above-mentioned technical proposal, in embodiments of the present invention, communication equipment carries out the cascade of data block not after channel coding, but carries out the cascade of data block again after modulation, and then improves the degree of parallelism in data handling procedure.So, the embodiment of the present invention can reduce data processing time, and guarantee is provided for the real-time of communication system.

Alternatively, as one embodiment, concatenation unit 603 is specifically for doing non-sequential cascade to the data block after multiple modulation and merging, obtain the new data stream after cascade merges.

For example, the element of at least two data blocks in the data block of concatenation unit 603 respectively after multiple modulation, which is interleaved, generates new data block.Assuming that there is N number of data block, then M data block can be picked out at random and be interleaved, wherein M<N, and M and N is positive integer.

Then, the element of the new data block after multiple intertextures is linked in sequence by concatenation unit 603, and new data stream is obtained after merging.That is, in cascade merging process, data are not done simple concatenated in order (such as by concatenation unit 603, first symbol of data block 1, second symbol ... of data block 1, the last symbol of data block 1, first symbol ... of data block 2, the last symbol of last data block).But cascade the new data block after intertexture, to improve diversity gain.So, the embodiment of the present invention can improve diversity gain, and then further improve the radio interface rate of communication system.

Processing unit 702, channel coding and rate-matched for multiple data blocks to be carried out with parallel block level, obtains the data block after multiple rate-matcheds.

For example, processing unit 702 carries out parallel data processing using each data block as an independent unit respectively.Such as, channel coding and rate-matched are carried out successively to data block.Parallel processing is carried out with the granularity of data block in channel coding and rate matching procedure, that is to say, that do not interdepended between each data block in data processing.

For example, obtained multiple data blocks are done cascade and merged after the medium-rate of processing unit 702 is matched, new data stream is obtained, and exports and carries out subsequent treatment to next stage module.Specifically, the element at least two data blocks that communication equipment can be in data block respectively after multiple rate-matcheds, which is interleaved, generates new data block.Assuming that there is N number of data block, then M data block can be picked out at random and be interleaved, wherein M<N, and M and N is positive integer.

It is pointed out that in general, interleave depth is bigger, then transmission performance is better, but the complexity calculated is raised, it is necessary to which more data are done with calculating and processing that position is moved.Therefore M selection can depend on compromise consideration of both transmission performance and complexity.Wherein, the number of data block of the number of the new data block of generation with being interleaved is identical.For example：The element of 4 data blocks is interleaved, The new data block so generated is also 4, and the element number of each data block does not change.

Processing unit 702, is additionally operable to the data flow after merging to cascade and is scrambled and modulated, the new data stream after being modulated.

Alternatively, as another embodiment, concatenation unit 703 is specifically for carrying out serial order arrangement by the element of at least two data blocks in the data block after multiple rate-matcheds, obtaining the first element sequence.Then, according to default rule, change element in first element sequence and put in order, obtain the Binary prime sequences.Finally, the new data block after multiple intertextures is obtained from second element sequence successively.

Similarly, the element of the new data block after multiple intertextures is linked in sequence by concatenation unit 703, and new data stream is obtained after merging.Data are not done simple concatenated in order by communication equipment, but the new data block after intertexture is cascaded, to improve diversity gain.So, the embodiment of the present invention can improve diversity gain, and then further improve the radio interface rate of communication system.
