Description

Data Transmission Method and Device Technical Field The present invention relates to wireless communication technologies, and in particular, to a data transmission method and device. Background technique

LTE divides different channels at the physical layer to carry different information. It is necessary to evaluate the coverage of each channel of LTE, identify the channel with limited coverage, and finally consider a method that can enhance the coverage of the channel.

The coverage of each channel of LTE can be evaluated according to the maximum coupling loss (Maximum Coupling Loss, MCL) value, and the smaller the MCL value, the more limited the coverage of the corresponding channel. The Physical Uplink Shared Channel (PUSCH) is used to transmit uplink data services. When the PUSCH is used for medium-rate data service transmission (hereinafter referred to as the data rate in the PUSCH), its MCL value is compared to the MCL value of other channels. Smallest, worst coverage, needs to improve its coverage. Wherein, the data rate in the PUSCH usually refers to a rate between 128kbps and 384kbps.

In order to improve coverage, a method of transmission time interval (Transmission Time Interval, TTI) bundling (TTTI bundling) can be used. In the prior art, ΤTI bundling can only be applied when the number of resource blocks (Resource Block, RB) is less than It is equal to 3 and the scene of quadrature phase shift keying (Quadrature Phase Shift Keying, QPSK) modulation. In this scenario, the maximum value of the transport block size (Transport Block Size, TBS) is 504 bits. Then, even if the initial transmission is 100% correct at this time, when 4 subframes are bound, the maximum data rate is only 504/4ms=126kbps, and the data rate in PUSCH is usually between 128kbps and 384kbps. Meet the rate requirement of the data rate in PUSCH. That is to say, the existing ΤΉ binding scheme cannot be directly applied in the data rate scenario in PUSCH, and needs to be considered A solution to improve coverage at data rates in PUSCH.

31 3 In Table 2, MCS is a modulation and coding scheme (Modulation and Coding Scheme, MCS) index, rv _ldx represents the redundancy version used in PUSCH data transmission, represents the modulation mode, and when it is equal to 2, it represents the QPSK modulation mode, 4 and 6 represent 16 quadrature amplitude modulation (Quadrature Amplitude Modulation, QAM) modulation mode and 64QAM modulation mode respectively.

In the prior art, the base station includes information such as the MCS index and the number of selected RBs w _PRB in the uplink scheduling command (UL grant), so as to schedule the transmission of uplink data. The base station may also configure the UE to perform data transmission on the PUSCH in a manner of TI binding. In the prior art, the application of the TTI bundling scheme can only be limited to the case where the number of RBs is less than or equal to 3 and the modulation mode is QPSK. Then, under this restriction, the TBS value that can be used when ΤΉ is bound is the value corresponding to w _PRB is 1-3 and / is 0-10. It can be seen from Table 1 that the maximum value of the TBS value at this time is 504.

As mentioned in the background art, for the TI binding scenario in which 4 consecutive subframes are bound, the TBS value at 504 cannot meet the data rate requirement in the PUSCH.

In order to meet the data rate requirements in the PUSCH, taking the data rate in the PUSCH as 384kbps as an example, when 4 TTIs are used for bundling and the Block Error Rate (Block Error Rate, BLER) is 10%, the TBS needs to be at least: 384 x 4/90% = 1707.

Combined with Table 1, the value of the set number closest to 1707 can be selected, for example, 1736 or 1800.

That is to say, in the embodiment of the present invention, the coverage requirements of the data rate in the PUSCH must be met. Requirements need to be satisfied at the same time: the RB is small, the QPSK modulation mode is adopted, and the TBS value is large. Wherein, a smaller RB means that the number of RBs is less than or equal to a specific value, such as 8, and a larger TBS value means that the TBS value can meet the data rate requirements in the PUSCH when the TBS is bound to the transmission mode, that is, the TBS value is at least It is: (data rate in PUSCH) X (number of bound ΤΉ)/(1-BLER), for example, the range is a value between [568,2152] and the value is in the existing table (Table 1) An existing value, such as 1736 or 1800. In the following embodiments, for the sake of simplicity, the number of RBs less than or equal to a specific value is referred to as a small RB, and the TBS value that can meet the data rate requirements in the PUSCH during TI bonding is referred to as a large TBS value.

However, it can also be seen from Table 1 that when the TBS value is 1736 or 1800, the corresponding modulation method is no longer QPSK and/or the corresponding number of RBs is no longer small, for example, / _ras = 14, N When _v =6, the corresponding TBS is 1736, but the modulation mode at this time is 16 QAM.

In the embodiment of the present invention, in order to meet the above conditions at the same time: the RB is small, the QPSK modulation mode is adopted, and the TBS value is large, Table 1 can be modified, and the modified table can be used as the second table. Can include:

Method 1: In the second table, when the number of RBs is less than or equal to a specific value and the modulation method corresponding to the TBS index is QPSK, the corresponding TBS value corresponds to the same number of RBs and the same TBS index in the first table The TBS value is obtained after modification, so that the modified TBS value can meet the rate requirement required for TI bonded transmission.

For example, the original TBS value corresponding to / _ras =8, w _PRB =3 is 392, but in the embodiment of the present invention, the TBS value corresponding to / _TBS =8, w _PRB =3 is changed to 1736. Mode 2: In the second table, when the number of RBs is less than or equal to a specific value and the TBS value can meet the rate requirements required for TI bonded transmission, the modulation method corresponding to the corresponding TBS index is the same as that in the first table It is obtained by modifying the modulation mode corresponding to the TBS index corresponding to the number of RBs and the same TBS value, and the modified modulation mode is QPSK:.

For example, w _PRB =3 and TBS=1736 correspond to / _ras =23, and the modulation mode when / _ras =23 is 64QAM, but in the embodiment of the present invention, the modulation mode when / _ras =23 is changed to QPSK:.

Mode 3: In the second table, when the modulation method corresponding to the TBS index is QPSK and the TBS value can meet the rate requirement required for Τ binding transmission, the corresponding number of RBs is greater than the number of RBs that can be selected during Τ binding transmission in the first table The maximum value of the number of RBs;

For example, in the prior art, the number of RBs that can be selected in the first table when TI is bound for transmission is 3, and in the embodiment of the present invention, the number of selectable RBs can be expanded, for example, to 8, then according to the first table (Table 1), when the number of selectable RBs is less than or equal to 8 , it is also possible to find the above-mentioned TBS value that satisfies the rate requirement required for TΉ bonded transmission and the corresponding modulation mode is QPSK:.

Specifically, the present invention provides the following examples.

FIG. 1 is a schematic flowchart of an embodiment of the data transmission method of the present invention, including:

Step 11: The UE selects a TBS value according to a preconfigured second table, the second table is used to describe the correspondence between the TBS value, the number of RBs, and the TBS index, and the number of RBs corresponding to the selected TBS value is less than Or equal to a specific value, the modulation mode corresponding to the TBS index corresponding to the selected TBS value is QPSK, and the selected TBS value can meet the rate requirements required for TI binding transmission;

Step 12: The UE transmits the data carried by the PUSCH using the bound TBS according to the selected TBS.

Wherein, in the embodiment of the present invention, the existing table, that is, Table 1 is called the first table, and the newly proposed table in the embodiment of the present invention is called the second table, and both the first table and the second table can be preconfigured within the UE.

In addition, the uplink data of the UE is scheduled by the base station, that is, before step 11, it may also include: the UE receives configuration information sent by the base station, and the configuration information is used to indicate that the bound TTI is used to transmit the data carried by the PUSCH; and, The UE receives the scheduling information sent by the base station, where the scheduling information includes the index of the MCS and the number of RBs.

After the UE receives the scheduling information, it can search for the index ™ _S of the corresponding TBS according to the index of the MCS contained therein and Table 2 (Table 2 can be pre-configured in the UE), and then according to ™, the number of RBs w _PRB and the second table (the prior art according to Table 1) to obtain the value of TBS. Then, according to the found TBS value and the received configuration information, the bound TTI can be used to transmit the data carried by the PUSCH. There is only the first table in the prior art, so the first table is used regardless of whether ΤΉ is bound or not. However, as described in the background, according to the existing first table, when ΤΉ is bound, when RB is less than or equal to 3 and The TBS under the QPSK modulation mode, that is, the TBS corresponding to w _PRB being 1-3 and / being 0-10 in Table 1 cannot meet the rate requirement of the data rate in the PUSCH. For this reason, a second table is newly proposed in the embodiment of the present invention, and the second table is used during TTI bundling. In the second table, the RB is small and the TBS corresponding to the QPSK modulation mode is large to satisfy the PUSCH data rate requirements.

The second table simultaneously satisfies the requirement that the RB is small, the QPSK modulation mode is adopted, and the TBS is large, so that the service data at the data rate in the PUSCH can be transmitted in a TI binding manner.

This embodiment proposes the second table above, which indicates that the value of TBS is relatively large, the RB corresponding to TBS is small, and the modulation mode corresponding to TBS is QPSK. Since the value of TBS is relatively large, it can meet the requirements of the PUSCH rate requirements, and greater Turbo coding gain and reduced overhead can be obtained, and a better MCL value can be obtained by using smaller RBs and QPSK. Therefore, the coverage of the data rate in the PUSCH can be improved by using the above method.

Further, when the TBS selected according to the second table uses the bound TI to transmit the data carried by the PUSCH, there will be a problem of losing more information bits according to the existing transmission mode. Taking the binding of 4 consecutive subframes as an example, in the prior art, when data is transmitted in a TI binding manner, the 4 redundant versions encoded in a transport block are respectively mapped to 4 consecutive TIs, and these 4 Redundancy version numbers can be 0, 2, 3, 1. After Turbo 1/3 encoding, the information bits need to be rate-matched according to the available resources. The redundant version number indicates the number of data selected during rate matching in the data obtained after Turbo 1/3 encoding. starting point. However, such a transmission method may cause loss of information bits.

For example, referring to FIG. 2, assuming that the TBS value=1736, and the corresponding number of RBs is 3, then the number of bits that can be transmitted in one TΉ=12 (the number of subcarriers in each RB)×12 (the number of subcarriers in each RB) The number of data symbols) x 3 (the number of RBs) X 2 (the number of bits corresponding to each QPSK modulation symbol) = 864 bits. To the 1736 information bits, a 24-bit cyclic check (Cyclic Redundancy Check, CRC) is first added, and then (1736+24) x 2 check bits are added to complete Turbo 1/3 encoding. The data to be transmitted in the way of ΤΉ binding includes information bits and parity bits, and different redundancy versions represent different starting positions of the selected data in the Turbo 1/3 encoded data, and different redundancy versions They are denoted as RV0, RV1, RV2, and RV3 respectively. It can be seen from FIG. 2 that when 864 bits of data are selected for transmission in each subframe, there will be unselected data between subframes, that is to say, some information bits are Lost, such as the unselected data between RV0 and RV1 is lost.

In order to solve this problem, the present invention provides the following embodiment.

FIG. 3 is a schematic flowchart of another embodiment of the data transmission method of the present invention,

Step 31 : Select TBS according to the second form. For details, see step 11.

Afterwards, the bound TBS can be used to transmit the data carried by the PUSCH according to the selected TBS, which may specifically include the following steps 32-33.

Step 32: Select the data carried by the PUSCH, the data carried by the PUSCH includes information bits, the size of the information bits is the selected TBS value, when the data carried by the PUSCH is selected, the storage of the information bits Start to select data within the position range, and continuously select all the information bits starting from the selected starting point.

Wherein, since the number of information bits is the TBS selected according to the second table, if the selection method in the prior art is used, some information bits will be lost. However, in this embodiment, the method of continuously selecting information bits is adopted. Since all the information bits starting from the selected starting point are continuously selected, there will be no discontinuity, and the position indicated by RV0 can be increased to the position indicated by RV1. The coverage of the information bits between the positions can reduce the number of lost information bits.

Optionally, in order to ensure that all the information bits starting from the selected starting point are continuously selected, the data that can be transmitted by the bound TΉ can be continuously and cyclically selected. For example, referring to FIG. 4, taking the data that can transmit 864 bits per subframe as an example In the scenario of 4-subframe binding, this embodiment can continuously select 864 x 4-bit data, and the corresponding redundancy version number of the continuously selected data, that is, 864 x 4-bit data, can be named RV0.

Optionally, if the starting position of RV0 is taken as the starting point, two pieces of 864-bit data can be selected continuously to cover 1736 bits of information bits, see Figure 5, and 864 X 2 data can also be selected continuously, the 864 2 The version corresponding to the data is RV0, and the remaining two pieces of 864-bit data can be selected continuously or separately, and FIG. 5 shows a schematic diagram of the separate selection.

Optionally, when selecting data above, the starting point of selection is located in the space where the information bits are located, specifically the position indicated by RV0, that is, the data is selected from the position indicated by RV0.

Optionally, during the initial transmission, transmit the data that is continuously selected starting from the position indicated by RV0, for example, transmit 864 x 4-bit data as shown in Figure 4 during the initial transmission, or 864 x 4 bits as shown in Figure 5 2 bits of data.

Step 33: Using the bound TI to transmit the selected data carried by the PUSCH.

For example, when 864 4-bit data are continuously selected and there are 4 bound TIs, the selected data is divided into 4 parts, and the 864-bit data of each part is transmitted within one TI.

In this embodiment, more data can be transmitted within a shorter time delay by adopting the TI binding method, reducing the Low transmission delay; by using a larger TBS, the Turbo coding gain can be made larger, and the overhead of header information and cyclic check (Cyclic Redundancy Check, CRC) is reduced; by using a smaller number of RBs, the link The equivalent noise during calculation is kept at a low level; the mapping method of ΤΉ binding is modified so that more information bits can be transmitted; by using the QPSK modulation method, compared with 16QAM and 64QAM, it has a better link budget. Larger MCLs are available. Through the above method, the coverage of the data rate in the PUSCH can be improved.

Fig. 9 is a schematic flowchart of an embodiment of a method for selecting data when TI is bound according to the present invention, including: Step 91: Determine the data that can be transmitted by the bound TI;

Step 92: Continuously loop to select the data that can be transmitted by the bound TI.

For example, if the number of bound ΤΉ is 4, the data that can be transmitted by each ΤΉ is 864 ratios Specifically, the data that can be transmitted by the bound TTI is 864 x 4-bit data. Afterwards, in the cache for storing data, 864 x 4-bit data are selected in a continuous cycle. For details, see Figure 4.

The data refers to bit-level data.

Optionally, the data is data carried by the PUSCH; optionally, the data carried by the PUSCH includes information bits, and the selected starting point is within the range of storage locations where the information bits are located.

Optionally, the selection starting point of the continuous loop selection is the position indicated by RV0.

Optionally, it may also include: during the initial transmission, transmitting the data selected in a continuous loop starting from the position indicated by the RV0.

In addition, the present invention can also provide an embodiment, the continuously selected data is not all the data that can be transmitted by the bound TΉ, but the continuously selected data similar to that shown in Figure 5 can cover at least part of the information bits, At least part of the information bits refers to the information bits starting from the selected starting point, that is, an embodiment can also be given:

Data is selected from within the storage location range of the information bits, and all information bits starting from the selected starting point are continuously selected.

Correspondingly, the present invention also provides a device for selecting data during TI binding, the device may be located in the UE, see FIG. 10, the device includes a determination module 101 and a selection module 102; the determination module 101 is used to determine the bound TI The data that can be transmitted; the selection module 102 is used to continuously and cyclically select the data that can be transmitted by the bound TI.

Optionally, the selection starting point selected continuously by the selection module is the position indicated by RV0.

Optionally, the device may further include: a transmission module, configured to transmit continuously cyclically selected data from the position indicated by RV0 during initial transmission.

In this embodiment, by continuously selecting all the information bits starting from the selected starting point, the number of lost information bits can be reduced.

In the above embodiment, the data may be the data carried by PUSCH. When the selected starting point is the same as the starting point of the information bit, the data carried by the PUSCH includes all the information bits. When the selected starting point is after the starting point of the information bit, the PUSCH The carried data includes part of the information bits, and the part of the information bits refers to all the information bits starting from the selected starting point. In addition, the size of the information bit is the selected TBS value. Furthermore, channel coding is usually performed before data transmission. Channel coding usually includes the following steps:

(1) Cyclic Redundancy Check (Cyclic Redundancy Check, CRC) addition: add a check block after the transmission block. Usually the check block is 24 bits, assuming that the transmission block is A bits, and the CRC is added to B bits, then B=A+24;

(2) Code block division and code block CRC addition: If B>6144, a total of B-bit transmission blocks and check blocks are divided, and a 24-bit CRC check block is added to each code block. Assuming that it is divided into C code blocks, the obtained code block can be expressed as: . , , _c ^..., _c ^— where, r is the sequence number of the code block, and is the number of bits in the code block with the sequence number ;

(3) Coding, taking Turbo coding as an example: for each code block, for the code block with the sequence number r, the coded bits include three coded streams, recorded as: H d ...,d _r — , = 0,1,2, A is the number of bits on the encoded stream of the code block with the sequence number r, Α= +4, where the encoded stream = 0 contains information bits, and the encoded stream = 1, 2 is Redundant bits added by Turbo encoding;

(4) Rate matching: For each code block, first perform sub-block interleaving on the three coded streams of each code block, and then perform bit selection and puncturing on the interleaved bits.

Among them, when performing sub-block interleaving for three coded streams , = 0, l, 2, design a matrix with columns and behaviors that satisfies

The minimum value of A≤(^L. c _M ), write the bits of each coded stream into the matrix by row, add empty bits when the bits of the coded stream are insufficient, perform column replacement on the matrix, and then read out the bit stream by column, The obtained bit stream is, v[ ^l) , i = 0,1,2, is the number of bits in each of the three bit streams of a code block after sub-block interleaving, and the stream = 0 contains information bit. Put these three bit streams into the cache, for PUSCH data, the size of the cache is , remember that the bits in the cache are: ^, =0,1,..., _¾ -1; where, _Wj = 0,l,..., _Kn -l. Therefore, the data arrangement in the cache can be referred to in FIG. 11, the front ^ ₁ bits contain information bits, and the following _2Π bits are check bits.

The process of bit selection and puncturing is as follows: Determine the starting position k ₀ of bit selection and the sequence length E after rate matching, and then refer to FIG. 12 , from. Initially, select bits sequentially among ¾, = 0, 1, ..., Λ^-1, and the selected bits are not empty bits. On the one hand, the sequence length after the rate matching of the code block whose sequence number is r can be determined as follows:

^If r≤C_ _l , then ¹ JE _r , No shell ¹ J , E _r =Λ^χρ _Μ χ「(?'/(:,; where, r is the sequence number of the code block; C is the number of code blocks obtained when the code block is divided; Rounding down, ", means rounding up.

/ = G'modC , mod means modulo operation;

G^GI(N _L xQ _m ), G is the total number of bits available for the transmission of a transport block in a subframe, that is, it represents the resources that a transport block can occupy in a subframe at the bit level;

When transmit diversity is used, N _L =2, and in other cases, ^ is equal to the number of layers mapped to one transport block;

0" is the value corresponding to the modulation mode. When the modulation mode is QPSK, Q _m =2; when the modulation mode is 16QAM, ρ _M =4; when the modulation mode is 64QAM, Q _m =6.

On the other hand, the bit selects the starting position. It can be calculated and determined by the following formula: Wherein, is the number of rows of the matrix used in sub-block interleaving; Λ ^ is the cache size of the bit stream after sub-block interleaving; rv, is the redundancy version number, and the values that can be taken are: rv _idx =Q, 1, 2 or 3.

For the code block with sequence number , the bits obtained after rate matching can be expressed as: … ,

(5) Code block concatenation: The bits obtained after the rate matching of each code block are sequentially connected to obtain the final coded bits, and the number of bits is G.

After the channel coding is completed, the G coded bits of a transport block are modulated, and then the modulation symbols are placed on corresponding resources of a subframe for transmission.

In the prior art, it may be configured to use bound TI to transmit data carried by the PUSCH, and one transmission of a transmission block occupies 4 subframes. When the transmission block is initially transmitted, 4 TTIs are used for binding, and the base station uses a positive acknowledgment (Acknowledgment, ACK) or negative acknowledgment (Negative Acknowledgment, NACK) bit to feed back whether the data within the 4 TTIs is detected correctly. If the UE receives the NACK feedback from the base station, it will retransmit the transport block after 16 ΤΉ, and the retransmission also uses 4 ΤΉ to bind. In the prior art, when the bound TTI is used to transmit data, when rate matching is performed, within the bound 4 subframes (or called ΤΉ), each subframe is calculated using a redundant version number, The 4 subframes can use different redundancy versions, for example, r _V , _A are 0, 2, 3, 1 in turn. For the schematic diagram of the FDD system, see FIG. Each ΤΉ of corresponds to a different redundancy version number.

As described in the above embodiment, when the bound TI is used to transmit the data carried by the PUSCH, the size of the transmission block is the TBS selected according to the second table, and the TBS value in the second table is larger,

The RB corresponding to TBS is small and the modulation method corresponding to TBS is QPSK. At this time, when rv _idx = 0, k ₀ (rv _lA = ) = R _block x2 , k ₀ (rv _ldx ^0) + E _r <K _n , and, when ^=1, ₊ E _r . That is to say, referring to FIG. 14, the information bits contained between ( _rv , ^M and ) in the cache are not selected, so that they cannot be transmitted, resulting in the loss of information bits. In order to reduce the loss of information bits, the present invention also provides the following the embodiment.

In the embodiment of the present invention, when selecting bits, all the information bits starting from the selected starting point are continuously selected. It can also be said that the bits that can be transmitted by the bound TΉ are selected continuously and cyclically. Specifically, the rate matching and code block concatenation during existing channel coding can be modified. It can be understood that, in order to correspond to the above embodiments, the selected bits may also be referred to as selected data, one bit is data of one bit, and the data is 0 or 1.

Referring to Figure 15, the present invention provides the following embodiment, including:

Step 151: Determine the number of bits that can be transmitted by the bound TI;

Wherein, the number of bits that can be transmitted by the bound ΉΉ is represented by H, H=GxN As mentioned above, G is the total number of bits available for transmission of a transmission block in a subframe, and N is the number of bits of the bound ΤΉ number, for example, N = 4.

Different from determining G corresponding to each TI in the prior art, the H determined in this embodiment corresponds to the bound TI, and H is the total number of bits available for transmission of a transport block in N bound TIs, That is, at the bit level, it represents the resources that a transport block can occupy in N bundles ΤΉ.

Step 152: Determine the sequence length after rate matching according to the number of bits that can be transmitted by the bound TI;

Step 153: Determine the start position of bit selection according to the unique redundancy version number. The difference from the prior art is that when determining the above-mentioned sequence length, G is used in the prior art, while H is used in this embodiment; when determining the above-mentioned starting position . At this time, in the prior art, one starting position is determined for each TI, but in this embodiment, one starting position is determined for N bound TIs.

Specifically, in this embodiment, the sequence length E after the rate matching of the code block with the sequence number _r can be determined as follows:

If r≤C_ _l, then ¹ J ' = Λ^χρ _Μ χ[ί?'/(:", no shell ¹ £ ' = Λ^χρ _Μ χ "(?'/(:]; wherein, r is the serial number of the code block; c is the number of code blocks obtained when the code block is divided; L" means rounding down, " means rounding up.

/ = G'modC , mod means modulo operation;

G' = H/(N _L xQ _m ), H is the total number of bits available for the transmission of a transport block in N bound ΤΉ, that is, at the bit level, it represents a transport block in N bound ΤΉ The resources that can be occupied within;

When transmit diversity is used, N _L =2, and in other cases, ^ is equal to the number of layers mapped to one transport block;

0" is the value corresponding to the modulation mode. When the modulation mode is QPSK, ρ _Μ =2; when the modulation mode is 16QAM, ρ _Μ =4; when the modulation mode is 64QAM, Q _m =6.

In this embodiment, the starting position of the ratio can be calculated and determined using the following formula:

2x ^x rv _idx + 2

Wherein, is the number of rows of the matrix used in sub-block interleaving; Λ ^ is the cache size of the bit stream after sub-block interleaving; rv, is the redundancy version number, and the values that can be taken are: rv _idx =Q, 1, 2 or 3. Optionally, when the bound ΤΉ is initially transmitted, r _V , _A is selected as 0, and k can be calculated in the order of rv _idx =2,3,\,0,2,3,1, ... during retransmission ₀ .

Step 154: In the cache of the sub-block interleaved bit stream, starting from the starting position of the bit selection, continuously cyclically select bits whose length is the sequence length after the rate matching, and obtain the rate-matched bit of each code block bit.

As shown in Figure 16, in cache = 0, 1, 1, at the time of initial transmission, slave. Starting from (rv,. =0), the bits of E _r ' calculated according to H are selected continuously.

The bit selected in this step 154 is the bit after the rate matching, for the code whose sequence number is block, the bits obtained after rate matching can be expressed as: ― E is calculated according to .

Optionally, corresponding to the above-mentioned embodiment, the bit stream after the sub-block interleaving is: after performing CRC addition, code block segmentation, code block CRC addition, and Turbo encoding on information bits whose size is TBS selected according to the second table The bit stream obtained after sub-block interleaving is performed on the coded stream.

Step 155: Perform code block concatenation on the bits after the rate matching of each code block; wherein, during the code block concatenation, sequentially connect the bits obtained after the rate matching of each code block to obtain a transmission block The final coded bits, the number of coded bits is .

Step 156: Modulate the concatenated bits of the code blocks, and transmit the modulated symbols in each TΉ of the bundled TΉ respectively.

Wherein, the number of bits after the concatenation of the code blocks is , then each ΤΉ transmits the modulated symbols corresponding to H/N bits.

Further, during retransmission, the starting position of the bound ΤΉ only corresponds to one redundant version, referring to FIG. 17 , during retransmission, the starting positions of N bound ΤΉ are based on rv = 2, rv , _A =3 , rv _idx = \ or ^ _Α =0 to determine.

In this embodiment, by modifying the existing processes such as rate matching and code block concatenation according to the above process, the loss of information bits can be reduced, thereby transmitting more information bits.
