Description

数据传输方法和设备 技术领域 本发明涉及无线通信技术, 尤其涉及一种数据传输方法和设备。 背景技术 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

为了节约成本, 使网络的部署更便捷, 运营商希望长期演进(Long Term Evolution, LTE )能够与现有的通用移动通信系统( Universal Mobile Telecommunication System, UMTS )使用相同的站址, 为了保证小区边缘 用户的通信质量, 这就需要 LTE能和 UMTS系统达到相同的覆盖范围。 LTE在物理层划分了不同的信道来承载不同的信息, 需要评估 LTE的各 个信道的覆盖范围, 识别出覆盖受限的信道, 最后考虑能够增强该信道覆 盖的方法。 In order to save costs and make network deployment more convenient, operators hope that Long Term Evolution (Long Term Evolution, LTE) can use the same site site as the existing Universal Mobile Telecommunications System (Universal Mobile Telecommunications System, UMTS), in order to ensure that the cell edge The user's communication quality, which requires LTE and UMTS system to achieve the same coverage. 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.

可以根据最大连接损耗 ( Maximum Coupling Loss, MCL )值评估 LTE 各个信道的覆盖范围, MCL值越小表明对应信道的覆盖范围越受限。 物 理上行共享信道(Physical Uplink Shared Channel, PUSCH ) 用于传输上 行数据业务, 当 PUSCH 用于中等速率的数据业务传输 (以下简称为 PUSCH中数据速率) 时, 其 MCL值相比其他信道的 MCL值最小, 覆盖 最差,需要提高其覆盖范围。其中, PUSCH中数据速率通常是指在 128kbps 到 384kbps之间的速率。 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.

为了提高覆盖范围, 可以釆用传输时间间隔 ( Transmission Time Interval, TTI ) 绑定( ΤΤΙ bunding ) 的方法, 现有技术中 ΤΉ绑定只能应 用在资源块 (Resource Block, RB ) 的个数小于等于 3 且四相相移键控 ( Quadrature Phase Shift Keying , QPSK ) 调制的场景。 在该场景下, 传 输块大小 (Transport Block Size, TBS ) 的最大值为 504 比特。 那么, 此 时即使初传 100%正确, 绑定 4 个子帧时, 数据速率最大也只有 504/4ms= 126kbps,而 PUSCH中数据速率通常在 128kbps到 384kbps之间, 釆用 ΤΉ绑定后就不能达到 PUSCH中数据速率的速率要求。 也就是说, PUSCH中数据速率场景下不能直接应用现有的 ΤΉ绑定方案, 需要考虑 PUSCH中数据速率时提高覆盖范围的解决方案。 发明内容 本发明提供一种数据传输方法和设备, 用以提高 PUSCH中数据速率 时的覆盖范围。 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. SUMMARY OF THE INVENTION The present invention provides a data transmission method and device for increasing the coverage of the data rate in the PUSCH.

31 3 表 2中, MCS是调制编码方式( Modulation and Coding Scheme, MCS ) 索引, rvldx代表 PUSCH数据传输时所釆用的冗余版本, 代表调制方式, 等于 2 时表示 QPSK调制方式, 4 和 6 分别代表 16 正交幅度调制 ( Quadrature Amplitude Modulation , QAM )调制方式和 64QAM调制方式。 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.

现有技术中,基站在上行调度命令( UL grant )中包含有 MCS索引 以及选取的 RB 个数 wPRB等信息, 从而调度上行数据的传输。 基站还可以 配置 UE釆用 ΤΉ绑定的方式进行 PUSCH的数据传输。 现有技术中, TTI 绑定方案的应用只能限制在 RB个数小于等于 3 , 且 QPSK调制方式的情 况。那么,在该限制条件下, ΤΉ绑定时可以釆用的 TBS值就是对应 wPRB为 1〜3且 / 为 0〜10的值, 从表 1可以看出, 此时 TBS值的最大值为 504。 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.

如背景技术中所述, 对于绑定 4个连续子帧的 ΤΉ绑定场景, TBS值 在 504时并不能满足 PUSCH中数据速率的要求。 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.

为了满足 PUSCH 中数据速率的要求, 以 PUSCH 中数据速率为 384kbps为例, 当釆用 4个 TTI绑定且误块率 ( Block Error Rate, BLER ) 为 10%时, TBS需要至少为: 384 x 4/90%= 1707。 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.

再结合表 1 ,可以选取与 1707最接近的设定个数的值,例如选为 1736 或者 1800。 Combined with Table 1, the value of the set number closest to 1707 can be selected, for example, 1736 or 1800.

也就是说, 本发明实施例中要满足 PUSCH中数据速率的覆盖范围要 求, 需要同时满足: RB较小、 釆用 QPSK调制方式和 TBS值较大。 其中, RB较小是指 RB的个数小于或等于特定值, 特定值例如为 8, TBS值较大 是指 TBS值能够在 ΤΉ绑定传输方式时满足 PUSCH中数据速率要求, 即 TBS值至少为:(PUSCH中数据速率) X (绑定的 ΤΉ的个数)/( 1-BLER ) , 例如范围为 [568,2152]之间的一个值且该值在现有表格(表 1 )中已存在的 值, 如 1736或 1800。 下面实施例中为了简单起见, 将 RB个数小于或等 于特定值称为 RB较小, 将能够在 ΤΉ绑定时满足 PUSCH中数据速率要 求的 TBS值称为 TBS值较大。 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.

但是, 从表 1也可以看出, 当 TBS值为 1736或 1800时, 其对应的调 制方式就不再是 QPSK和 /或对应 RB个数也不再较小,例如,/ ras = 14 , Nv =6 时对应的 TBS是 1736, 但是, 此时的调制方式是 16 QAM。 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.

本发明实施例中为了同时满足上述的条件: RB较小、 釆用 QPSK调 制方式和 TBS值较大, 可以对表 1进行修改,将修改后的表格作为第二表 格。 可以包括: 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:

方式一: 第二表格中, 在 RB个数小于或等于特定值以及 TBS索引对 应的调制方式为 QPSK时对应的 TBS值,是对第一表格中相同的 RB个数 和相同的 TBS索引对应的 TBS值进行修改后得到的, 使得修改后的 TBS 值能够满足 Τ Ή绑定传输时所需的速率要求。 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.

例如, 原来 /ras=8, wPRB =3对应的 TBS值为 392, 而本发明实施例中 将 /TBS =8, wPRB =3 对应的 TBS值更改为 1736。 方式二: 第二表格中, 在 RB个数小于或等于特定值以及 TBS值能够满足 ΤΉ绑定传输时所需的速 率要求时对应的 TBS索引对应的调制方式,是对第一表格中相同的 RB个 数和相同的 TBS值对应的 TBS索引对应的调制方式进行修改后得到的, 是的修改后的调制方式为 QPSK:。 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:.

例如, 原来 wPRB =3、 TBS=1736对应 /ras=23 , 而 /ras=23 时的调制方式 是 64QAM, 而本发明实施例中将 /ras=23时的调制方式更改为 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:.

方式三: 第二表格中,在 TBS索引对应的调制方式为 QPSK以及 TBS 值能够满足 ΤΉ绑定传输时所需的速率要求时对应的 RB个数大于第一表 格在 ΤΉ绑定传输时能够选择的 RB个数的最大值; 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;

例如, 现有技术中, 第一表格在 ΤΉ绑定传输时能够选择的 RB个数 的最大值为 3 , 而本发明实施例中可以将可以选择的 RB个数扩大, 例如, 扩大到 8, 那么根据第一表格(表 1 ) , 在能够选择的 RB个数小于或等于 8时,也可以找到上述的满足 ΤΉ绑定传输时所需的速率要求的 TBS值且 对应调制方式为 QPSK:。 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:.

具体的, 本发明给出如下实施例。 Specifically, the present invention provides the following examples.

图 1为本发明数据传输方法一实施例的流程示意图, 包括: FIG. 1 is a schematic flowchart of an embodiment of the data transmission method of the present invention, including:

步骤 11 : UE根据预先配置的第二表格选择 TBS值, 所述第二表格用 于描述 TBS值、 RB个数、 TBS 索引之间的对应关系, 所述选择的 TBS 值对应的 RB个数小于或等于特定值, 所述选择的 TBS值对应的 TBS索 引对应的调制方式为 QPSK,且所述选择的 TBS值能够满足 ΤΉ绑定传输 时所需的速率要求; 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;

步骤 12: UE根据所述选择的 TBS釆用绑定的 ΤΉ传输 PUSCH承载 的数据。 Step 12: The UE transmits the data carried by the PUSCH using the bound TBS according to the selected TBS.

其中, 本发明实施例中, 将现有表格, 即表 1称为第一表格, 而将本 发明实施例中新提出的表格称为第二表格, 第一表格和第二表格都可以预 先配置在 UE内。 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.

另外, UE的上行数据是由基站调度的, 即, 在步骤 11之前还可以包 括: UE接收基站发送的配置信息, 该配置信息用于指示釆用绑定的 TTI 传输 PUSCH承载的数据; 以及, UE接收基站发送的调度信息, 该调度信 息中包括 MCS的索引和 RB的个数。 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.

当 UE接收到调度信息后, 可以根据其中包含的 MCS 的索引和表 2 (表 2可以预先配置在 UE内 ) 查找得到对应的 TBS的索引 ™S, 之后再 根据 ™、 RB 的个数 wPRB和第二表格(现有技术根据表 1 ) 查找得到 TBS 的值。 之后就可以根据查找到的 TBS的值, 以及接收到的配置信息, 釆用 绑定的 TTI传输 PUSCH承载的数据。 现有技术中只有第一表格, 因此不 论 ΤΉ是否绑定都釆用第一表格, 但是, 如背景技术所述, 按照现有的第 一表格, ΤΉ绑定时, 在 RB小于或等于 3且 QPSK调制方式下的 TBS , 即表 1中 wPRB为 1〜3且 / 为 0〜10对应的 TBS是不能满足 PUSCH中数据 速率的速率要求的。 为此, 本发明实施例中新提出一个第二表格, 在 TTI 绑定时釆用该第二表格, 该第二表格中在 RB较小且 QPSK调制方式所对 应的 TBS较大以满足 PUSCH中数据速率要求。 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.

第二表格同时满足了 RB较小、 釆用 QPSK调制方式和 TBS较大, 这 样就可以釆用 ΤΉ绑定的方式传输 PUSCH中数据速率时的业务数据。 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.

本实施例提出了如上的第二表格,该第二表格表明其中的 TBS的值较 大、 TBS对应的 RB较小且 TBS对应的调制方式为 QPSK, 由于 TBS的值 较大, 能够满足 PUSCH中速率的要求, 并且可以获得更大的 Turbo编码 增益和减少开销, 釆用较小的 RB和 QPSK可以得到较好的 MCL值, 因 此, 釆用上述方式可以提高 PUSCH中数据速率时的覆盖范围。 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.

进一步的, 在根据第二表格选择的 TBS釆用绑定的 ΤΉ传输 PUSCH 承载的数据时, 如果按照现有的传输方式会存在丟失较多的信息比特的问 题。 以绑定连续的 4个子帧为例, 现有技术在釆用 ΤΉ绑定方式传输数据 时, 将一个传输块编码后的 4个冗余版本分别映射到连续的 4个 ΤΉ内, 这 4个冗余版本号可以是 0、 2、 3、 1。 信息比特在进行 Turbo 1/3编码后, 需要根据可用的资源大 d、进行速率匹配, 冗余版本号表示的是速率匹配时 所选取的数据在 Turbo 1/3编码后所得到的数据中的起始位置。 但是这样 传输方式可能造成信息比特丟失。 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.

例如, 参见图 2, 假设 TBS值 =1736, 对应的 RB个数为 3 , 那么在一 个 ΤΉ 内可以传输的比特数 =12 (每个 RB 内的子载波个数) X 12 (每个 RB内的数据符号个数) x 3 ( RB个数) X 2 (每个 QPSK调制符号对应的 比特数) =864 比特。 1736 个信息比特首先添加 24 比特的循环校验 ( Cyclic Redundancy Check, CRC ) , 再添加 ( 1736+24 ) χ 2个校验比特 后完成 Turbo 1/3编码。 釆用 ΤΉ绑定的方式所要传输的数据包括信息比 特和校验比特, 不同的冗余版本代表所选取的数据在 Turbo 1/3编码后的 数据中的不同起始位置, 不同的冗余版本分别表示为 RV0、 RV1、 RV2和 RV3 , 从图 2可以看出, 当每个子帧选取 864比特的数据进行传输时, 子 帧之间会存在没有被选取的数据, 也就是说一些信息比特被丟失, 如 RV0 和 RV1之间的没被选取的数据就被丟失了。 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.

为了解决这一问题, 本发明给出下面的一个实施例。 In order to solve this problem, the present invention provides the following embodiment.

图 3为本发明数据传输方法另一实施例的流程示意图, FIG. 3 is a schematic flowchart of another embodiment of the data transmission method of the present invention,

步骤 31 : 根据第二表格选择 TBS。 具体内容可以参见步骤 11。 Step 31 : Select TBS according to the second form. For details, see step 11.

之后可以根据选择的 TBS釆用绑定的 ΤΉ传输 PUSCH承载的数据, 具体可以包括下面的步骤 32〜33。 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.

步骤 32: 选取 PUSCH承载的数据, 所述 PUSCH承载的数据包括信 息比特, 所述信息比特的大小为所述选择的 TBS值, 在选取所述 PUSCH 承载的数据时, 在所述信息比特的存储位置范围内开始选取数据, 且连续 选取全部的从选取起始点开始的信息比特。 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.

其中, 由于信息比特的个数为根据第二表格选择的 TBS , 如果按照现 有技术的选取方式, 会丟失部分信息比特。 而本实施例中釆用连续选取信 息比特的方式, 由于全部的从选取起始点开始的信息比特都是连续选取 的, 不会出现不连续的情况, 就可以增加从 RV0指示的位置到 RV1指示 的位置之间对信息比特的覆盖, 就可以降低信息比特丟失的个数。 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.

可选的, 为了保证连续选取全部的从选取起始点开始的信息比特, 可 以连续循环选取绑定的 ΤΉ能够传输的数据, 例如, 参见图 4, 以每个子 帧能够传输 864比特的数据为例, 在 4子帧绑定的场景下, 本实施例可以 连续选取 864 x 4比特的数据, 该连续选取的数据, 也就是 864 x 4比特的 数据, 对应的冗余版本号可以命名为 RV0。 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.

可选的, 如果以 RV0的起始位置为起始点, 连续选取 2个 864比特 的数据可以覆盖住 1736比特的信息比特, 参见图 5 , 也可以连续选取 864 X 2的数据,该 864 2的数据对应的版本为 RV0,剩余的 2个 864比特的 数据可以连续选取, 也可以分离选取, 图 5给出了分离选取的示意。 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.

可选的, 上述选取数据时, 选取起始点位于信息比特所在的空间内, 具体可以是 RV0指示的位置, 也就是从 RV0指示的位置开始选取数据。 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.

可选的, 在初传时, 传输从 RV0指示的位置开始且连续选取的数据, 例如, 初传时传输如图 4所示的 864 x 4比特的数据, 或者如图 5所示的 864 x 2比特的数据。 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.

步骤 33 : 釆用绑定的 ΤΉ传输选取的所述 PUSCH承载的数据。 Step 33: Using the bound TI to transmit the selected data carried by the PUSCH.

例如, 连续选取 864 4比特的数据且绑定的 ΤΉ为 4个时, 将选取 的数据分为 4份, 每份的 864比特的数据在一个 ΤΉ内传输。 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.

(5)码块级联: 将每个码块速率匹配后得到的比特依次进行顺序连 接, 得到最终的编码比特, 比特个数为 G。 (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.

信道编码完成后, 将一个传输块的这 G个编码比特进行调制, 再将调 制符号放到一个子帧的相应资源上进行传输。 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.

在现有技术中, 可以配置釆用绑定的 ΤΉ来进行 PUSCH承载的数据 的传输, 传输块的一次传输占用 4个子帧。 在传输块进行初传时, 釆用 4 个 ΤΉ进行绑定, 基站通过一个肯定确认 ( Acknowledgment, ACK)或否 定确认 ( Negative Acknowledgment, NACK) 比特来反馈这 4个 TTI内的 数据是否检测正确。 若 UE收到基站的 NACK反馈, 将在 16个 ΤΉ后进 行传输块的重传, 重传也釆用 4个 ΤΉ绑定。 现有技术中在釆用绑定的 TTI传输数据时, 在进行速率匹配时, 绑定 的 4个子帧 (或称为 ΤΉ) 内, 每个子帧都釆用一个冗余版本号进行 的 计算, 4个子帧可釆用不同的冗余版本, 比如 rV,A依次为 0、 2、 3、 1, FDD 系统的示意图参见图 13, 釆用绑定的 ΤΉ传输数据时, 绑定的 ΤΉ中的 每个 ΤΉ对应不同的冗余版本号。 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.

如上面的实施例所述,当釆用绑定的 ΤΉ传输 PUSCH承载的数据时, 传输块的大小为根据第二表格选择的 TBS, 该第二表格中的 TBS值较大、 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,

TBS对应的 RB较小且 TBS对应的调制方式为 QPSK, 此时, 当 rvidx = 0时, k0(rvlA = ) = R blockx2 , k0(rvldx ^0) + Er <Kn , 并 且 , 当 ^=1 时 , + Er。 也就是说, 参见图 14, 緩存中 (rv,^M和 之间包含的信息比特就没有被选取,从而不能传输,造成信息比特的丟失。 为了降低信息比特的丟失, 本发明还给出如下的实施例。 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.

本发明实施例中, 在选取比特时, 连续选取全部的从选取起始点开始 的信息比特, 也可以说, 连续循环选取绑定的 ΤΉ能够传输的比特。 具体 可以对现有信道编码时的速率匹配和码块级联进行修改。 可以理解的是, 为了与上面的实施例对应, 选取比特也可以称为选取数据, 一个比特为一 位的数据, 该数据为 0或 1。 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.

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.

其中, 是子块交织时釆用的矩阵的行数; Λ ^是緩存子块交织后 的比特流的緩存的大小; rv, 是冗余版本号, 可以取的值为: rvidx=Q, 1, 2 或 3。 可选的, 在绑定的 ΤΉ进行初传时, rV,A选为 0, 在重传时可以按照 rvidx=2,3,\ ,0,2,3,1, …的顺序计算 k0 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 .

步骤 154: 在緩存子块交织后的比特流的緩存中, 从该比特选择的起 始位置开始, 连续循环选取长度为该速率匹配后的序列长度的比特, 得到 每个码块速率匹配后的比特。 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.

其中, 码块级联后的比特个数为 则每个 ΤΉ传输 H / N个比特对应 的调制后的符号。 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.
