技术领域Technical field

本公开涉及通信技术领域，尤其涉及一种信息数据块的处理方法和发送端。The present disclosure relates to the field of communications technologies, and in particular, to a method and a transmitting end of an information data block.

背景技术Background technique

随着移动通信业务需求的发展变化，第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)等多个组织对未来移动通信***都开始研究新的无线通信***，即5G新接入技术(5 Generation New RAT，5G NR)***。在5G NR***中一个重要的需求为低时延高可靠的通信，例如：低时延高可靠(Ultra Reliable & Low Latency Communication，URLLC)等传输方案。With the development of mobile communication services, many organizations such as the 3rd Generation Partnership Project (3GPP) have begun to research new wireless communication systems for future mobile communication systems, namely 5G new access technologies (5 Generation New RAT, 5G NR) system. An important requirement in the 5G NR system is low latency and high reliability communication, such as transmission schemes such as Ultra Reliable & Low Latency Communication (URLLC).

对于URLLC业务，一般是小包，即每次要传输的信息比特很小，另一方面，URLLC业务对应于可靠性的要求非常高，比如误块率低于1E-5(1乘以10的负5次幂)，如果要达到这样高的可靠性，通常需要特别低的编码码率。所以特别小的包和给定资源下特别低的码率，都可能产生特别小的信息数据块。然而，在实际应用中，特别小的信息数据块如果直接进行信道编码，如直接采用低密度奇偶校验(Low Density Parity Check，LDPC)等信道编码，会出现编码性能下降的情况，具体表现为在低信噪比(Signal Noise Ratio，SNR)区域误块率高，在高SNR区域出现误码平层(error floor)。For the URLLC service, it is generally a small packet, that is, the information bits to be transmitted are small at a time. On the other hand, the URLLC service has a very high reliability requirement, such as a block error rate lower than 1E-5 (1 times 10 times negative) A power of 5), if such high reliability is to be achieved, a particularly low coding rate is usually required. Therefore, a particularly small packet and a particularly low code rate for a given resource may result in a particularly small block of information. However, in practical applications, if the information block of a particularly small information block is directly subjected to channel coding, such as direct channel coding such as Low Density Parity Check (LDPC), the coding performance may be degraded. In the low signal-to-noise ratio (SNR) region, the block error rate is high, and in the high SNR region, an error floor occurs.

可见，目前存在编码性能比较低的问题。It can be seen that there is currently a problem of relatively low coding performance.

As shown in FIG. 1 , the device includes a transmitting end 11 and a receiving end 12 , where the sending end 11 can be a terminal or a network side device, where the terminal can It is a User Equipment (UE) or other terminal device, such as a mobile phone, a Tablet Personal Computer, a Laptop Computer, a personal digital assistant (PDA), and a mobile Internet device.

The network side device may be a base station, for example, a macro station, an LTE eNB, a 5G NR NB, etc.; the network side device may also be a small station, such as a low power node (LPN: low power node), a pico, a femto, or the like, or a network. The side device may be an access point (AP); the base station may also be a network node formed by a central unit (CU) and a plurality of transmission reception points (TRPs) that are managed and controlled. It should be noted that the specific type of the network side device is not limited in the embodiment of the present disclosure. The receiving end 12 may also be a terminal or a network side device.

请参见图2，图2是本公开实施例提供的一种信息数据块的处理方法的流程图，如图2所示，包括以下步骤：Referring to FIG. 2, FIG. 2 is a flowchart of a method for processing an information data block according to an embodiment of the present disclosure. As shown in FIG. 2, the method includes the following steps:

201、发送端对信息数据块进行预处理，得到预处理数据块；201. The sending end performs pre-processing on the information data block to obtain a pre-processed data block.

202、对所述预处理数据块进行信道编码，并向接收端传输信号，所述信号为所述预处理数据块经过所述信道编码得到的信号；202. Perform channel coding on the preprocessed data block, and transmit a signal to the receiving end, where the signal is a signal obtained by the preprocessed data block by using the channel coding;

其中，上述信息数据块可以是发送缓存器中需要发送的信息数据块。选的，可以是特别小的信息数据块，例如：URLLC业务的信息数据块，或者可以是其他要求低时延，以及高可靠性业务的信息数据块，或者特定资源下产生的特别小的信息数据块等等。另外，本公开实施例中，特别小的信息数据块可以定义为长度小于预设门限值的信息数据块，例如：预先定义一个X，则长度小于X的信息数据块为特别小的信息数据块。当然，本公开实施例中，并不限定上述信息数据块为特别小的信息数据块，例如：上述信息数据块还可以是长度等于上述预设门限值的信息数据块，或者长度比该预设门限值大的信息数据块。The information data block may be an information data block that needs to be sent in the transmit buffer. Alternatively, it may be a particularly small piece of information data, such as an information data block of a URLLC service, or may be other information data blocks requiring low latency, and high reliability services, or particularly small information generated under specific resources. Data blocks and more. In addition, in the embodiment of the present disclosure, a particularly small information data block may be defined as an information data block whose length is less than a preset threshold value. For example, if an X is defined in advance, the information data block whose length is smaller than X is particularly small information data. Piece. Of course, in the embodiment of the present disclosure, the information data block is not limited to a particularly small information data block. For example, the information data block may be an information data block having a length equal to the preset threshold, or a length ratio. Set the information data block with a large threshold.

上述预处理可以是发送端预先设置的、协议中预先定义，或者发送端与接收端预先协商的处理，包括但不限于重复操作、编码操作和填充操作。The pre-processing may be pre-defined by the sender, pre-defined in the protocol, or pre-negotiated by the sender and the receiver, including but not limited to repeated operations, encoding operations, and padding operations.

当得到上述预处理数据块后，可以进行信道编码，进而发送经过信道编码得到的信号。由于在信道编码前进行了预处理，从而可以提高信道编码的性能。After obtaining the preprocessed data block, channel coding may be performed, and then the signal obtained by channel coding may be transmitted. Since the pre-processing is performed before channel coding, the performance of channel coding can be improved.

另外，发送端指示所述信号的所述信息数据块在信道编码前经过所述预处理，从而接收端可以正确地从接收到的信号中获取到上述信息数据块，进而保证信息数据块传输的性能。例如：接收端对发送端发送的信号进行译码，得到预处理数据块(或者称作译码结果)，然而，对所述预处理数据块进行所述预处理的反操作，得到所述信息数据块。其中，上述预处理的反操作可以是理解为，为了得到上述信息数据块进行的与上述预处理的相反操作。例如：上述预处理为编码操作，则该反操作为译码，以得到上述信息数据块；或者上述预处理为填充操作，则该反操作为去除填充的部分，以得到上述信息数据块；或者上述预处理为重复操作，则该反操作为去除重复的部分，以得到上述信息数据块。In addition, the transmitting end indicates that the information data block of the signal passes the pre-processing before channel coding, so that the receiving end can correctly acquire the information data block from the received signal, thereby ensuring the transmission of the information data block. performance. For example, the receiving end decodes the signal sent by the transmitting end to obtain a pre-processed data block (or a decoding result), but performs the inverse operation of the pre-processing on the pre-processed data block to obtain the information. data block. The reverse operation of the pre-processing described above may be understood as the reverse operation of the pre-processing described above in order to obtain the above-mentioned information data block. For example, if the foregoing preprocessing is an encoding operation, the inverse operation is decoding to obtain the information data block; or the preprocessing is a filling operation, and the reverse operation is to remove the padded portion to obtain the information data block; or The above preprocessing is a repetitive operation, and the reverse operation is to remove the duplicated portion to obtain the above information data block.

需要说明的是，本公开实施例中对接收端的行为不作限定。It should be noted that the behavior of the receiving end is not limited in the embodiment of the present disclosure.

以及，由于仅是信道编码前对信息数据块进行上述预处理，从而可以实现用比较低的实现复杂度解决信道编码在处理特别小的信息数据块时性能差的问题，从而有效实现低时延高可靠的数据传输。Moreover, since the above pre-processing is performed on the information data block only before the channel coding, it is possible to solve the problem that the channel coding has poor performance when processing a particularly small information data block with a relatively low implementation complexity, thereby effectively implementing low latency. Highly reliable data transmission.

作为一种可选的实施方式，所述发送端对信息数据块进行预处理，得到预处理数据块，包括：As an optional implementation manner, the sending end performs pre-processing on the information data block to obtain a pre-processed data block, including:

所述发送端对所述信息数据块添加CRC，并对添加的所述CRC和所述信息数据块进行所述预处理，得到预处理数据块。The transmitting end adds a CRC to the information data block, and performs the pre-processing on the added CRC and the information data block to obtain a pre-processed data block.

该实施方式中，可以实现在添加CRC的情况下，对CRC和所述信息数据块一起进行上述预处理，也就是说，在添加CRC后再进行上述预处理，从而可以降低接收端从接收到的信号中得到上述信息数据块和CRC的复杂度。因为，接收端对发送端发送的信号进行反操作过程中，可以将CRC和信息数据块作为一个整体进行处理。例如：接收端对发送端发送的信号进行译码，得到预处理数据块，之后，对所述预处理数据块进行所述预处理的反操作，得到所述信息数据块和CRC；对所述CRC进行校验；若校验通过，则输出所述信息数据块。In this implementation manner, in the case of adding a CRC, the foregoing pre-processing is performed on the CRC and the information data block together, that is, after the CRC is added, the foregoing pre-processing is performed, thereby reducing the receiving end from receiving. The complexity of the above information data block and CRC is obtained in the signal. Because the receiving end performs the reverse operation on the signal sent by the transmitting end, the CRC and the information data block can be processed as a whole. For example, the receiving end decodes the signal sent by the transmitting end to obtain a pre-processed data block, and then performs the inverse operation of the pre-processing on the pre-processed data block to obtain the information data block and the CRC; The CRC performs verification; if the verification passes, the information data block is output.

需要说明的是，本公开实施例中，对信息数据块进行预处理，得到预处理数据块并不限定为，对CRC和信息数据块进行预处理，得到预处理数据块的方式，例如：还可以是其他方式，如在添加CRC的情况下，可以只对信息数据块进行上述预处理，以得到相应的预处理数据块，或者在一些实施方式，添加其他校验码，则可以对该校验码和信息数据块进行上述预处理，以得到相应的预处理数据块。It should be noted that, in the embodiment of the present disclosure, the pre-processing of the information data block is not limited to the pre-processing of the CRC and the information data block, and the manner of pre-processing the data block is obtained, for example: In other cases, for example, in the case of adding a CRC, the above pre-processing may be performed only on the information data block to obtain a corresponding pre-processed data block, or in some embodiments, other check codes may be added to the school. The verification and information data blocks are subjected to the above pre-processing to obtain corresponding pre-processed data blocks.

作为一种可选的实施方式，所述信息数据块的长度小于预设门限值，所述预处理数据块的长度大于或者等于所述预设门限值。As an optional implementation manner, the length of the information data block is less than a preset threshold, and the length of the pre-processed data block is greater than or equal to the preset threshold.

其中，上述预设门限值可以是发送端预先设置的、协议中预先定义的或者发送端与接收端预先协商确定的等等。例如：上述预先门限值为50或者45或者55等等，对此不作限定。而上述预处理数据块可以是本公开实施例中提供任一实施方式中的预处理数据块，例如：上述预处理数据块为仅对信息数据块进行预处理，得到的预处理数据块，或者上述预处理数据块为仅对CRC和信息数据块进行预处理，得到的预处理数据块。The preset threshold may be preset by the sending end, predefined in the protocol, or determined by the sending end and the receiving end in advance. For example, the foregoing threshold value is 50 or 45 or 55, etc., and is not limited thereto. The pre-processed data block may be the pre-processed data block in any of the embodiments provided in the embodiment of the present disclosure. For example, the pre-processed data block is a pre-processed data block that is preprocessed only by the information data block, or The preprocessed data block is a preprocessed data block obtained by preprocessing only the CRC and the information data block.

由于信息数据块的长度小于上述预设门限值，且上述预处理数据块的长度大于或者等于上述预设门限值，这样可以实现信息数据块经过上述预处理后，可以增加其长度，从而可以避免特别小的信息数据块时性能差的问题，进而有效实现低时延高可靠的数据传输。另外，通过上述方式也可以确定，本公开实施例中预处理可以为能够让信息数据块的长度变得大于或者等于上述预设门限值的处理方式。The length of the information data block is less than the preset threshold, and the length of the pre-processed data block is greater than or equal to the preset threshold, so that the information data block can be increased in length after the pre-processing. The problem of poor performance in the case of particularly small information data blocks can be avoided, thereby effectively achieving low latency and high reliability data transmission. In addition, it can be determined by the foregoing manner that the pre-processing in the embodiment of the present disclosure may be a processing manner that enables the length of the information data block to become greater than or equal to the preset threshold value.

可选的，该实施方式，上述预处理包括如下至少一项：Optionally, in this implementation manner, the foregoing pre-processing includes at least one of the following:

其中，上述预处理包括如下至少一项可以理解为，上述预处理可以包括重复操作、编码操作和填充操作中的任意一项或者任意多项。例如：上述预处理可以是重复操作、编码操作或者填充操作，或者上述预处理可以是重复操作和编码操作，或者上述预处理可以是重复操作、编码操作和填充操作，或者上述预处理可以是编码操作和填充操作等等，此处不一一列出。Wherein, the foregoing pre-processing includes at least one of the following: It may be understood that the foregoing pre-processing may include any one or more of a repeating operation, an encoding operation, and a filling operation. For example, the above preprocessing may be a repetitive operation, an encoding operation or a filling operation, or the preprocessing may be a repetitive operation and an encoding operation, or the preprocessing may be a repetitive operation, an encoding operation, and a filling operation, or the preprocessing may be encoding. Operation and filling operations, etc., are not listed here.

可选的，基站配置或动态通知预设门限值L，基站配置或动态通知重复次数T，可以得到每次重复中所包含的比特数为L/T，当信息数据块的比特数小于L/T时，可以首先进行填充，达到L/T，然后重复T次，得到预处理数据块。这里的预处理操作的通知可以是有基站配置或动态通知给终端的。Optionally, the base station configuration or the dynamic notification preset threshold value L, the base station configuration or the dynamic notification repetition number T, can obtain the number of bits included in each repetition is L/T, when the number of bits of the information data block is less than L For /T, you can first fill, reach L/T, and then repeat T times to get the preprocessed data block. The notification of the pre-processing operation here may be configured by the base station or dynamically notified to the terminal.

其中，上述重复操作可以是对信息数据块进行重复操作，或者可以是对信息数据块和CRC进行重复操作，也就是说，在添加CRC后再进行重复操作，以使得预处理数据块的长度大于或者等于上述预设门限值。由于是进行重复操作，从而接收端可以直接去除重复内容，以得到信息数据块，从而降低复杂度。例如：可以把信息数据块，或者把信息数据块和CRC先重复L次，达到一定的长度(大于或者等于上述预设门限值)后，得到预处理数据块，之后再进行信道编码，并向接收端传输信号。The above repeated operation may be a repeated operation on the information data block, or may be repeated operations on the information data block and the CRC, that is, after the CRC is added, the repeated operation is performed, so that the length of the preprocessed data block is greater than Or equal to the above preset threshold. Since the repeated operation is performed, the receiving end can directly remove the duplicate content to obtain the information data block, thereby reducing the complexity. For example, the information data block may be repeated, or the information data block and the CRC may be repeated L times to reach a certain length (greater than or equal to the preset threshold value), and then the preprocessed data block is obtained, and then the channel coding is performed, and then The signal is transmitted to the receiving end.

而上述编码操作可以是对信息数据块进行编码操作，或者可以是对信息数据块和CRC进行编码操作，也就是说，在添加CRC后再进行编码操作，以使得预处理数据块的长度大于或者等于上述预设门限值。例如：对信息数据块，或者对信息数据块和CRC信道编码方式进行编码，如采用码率为M(为编码信息块的长度)/X(为上述预设门限值)的卷积编码或RM编码方式等编码方式，对此不作限定。由于是进行编码操作，从而接收端可以直接进行译码，以得到信息数据块，从而降低复杂度。例如：可以把信息数据块，或者把信息数据块和CRC先做一次编码，达到一定的长度(大于或者等于上述预设门限值)后，得到预处理数据块，之后再进行信道编码，并向接收端传输信号。The foregoing encoding operation may be an encoding operation on the information data block, or may be an encoding operation on the information data block and the CRC, that is, the encoding operation is performed after adding the CRC, so that the length of the preprocessed data block is greater than or It is equal to the above preset threshold. For example, encoding an information data block, or encoding an information data block and a CRC channel, such as a convolutional code using a code rate of M (which is the length of the coded block) / X (which is the predetermined threshold) The encoding method such as the RM encoding method is not limited thereto. Since the encoding operation is performed, the receiving end can directly decode the information data block to obtain the information data block, thereby reducing the complexity. For example, the information data block may be encoded, or the information data block and the CRC may be encoded once to reach a certain length (greater than or equal to the preset threshold value), and then the preprocessed data block is obtained, and then the channel coding is performed, and then The signal is transmitted to the receiving end.

而上述填充操作可以是对信息数据块进行填充操作，或者可以是对信息数据块和CRC进行填充操作，也就是说，在添加CRC后再进行填充操作，以使得预处理数据块的长度大于或者等于上述预设门限值。例如：在添加CRC后再填充若干个0，以使得到预处理数据块的长度大于或者等于上述预设门限值。由于是进行填充操作，从而接收端可以去除填充内容，以得到信息数据块，从而降低复杂度。例如：可以把信息数据块，或者把信息数据块和CRC先填充0，达到一定的长度(大于或者等于上述预设门限值)后，得到预处理数据块，之后再进行信道编码，并向接收端传输信号。The padding operation may be a padding operation on the information data block, or may be a padding operation on the information data block and the CRC, that is, after the CRC is added, the padding operation is performed, so that the length of the preprocessed data block is greater than or It is equal to the above preset threshold. For example, after adding the CRC, a plurality of zeros are filled, so that the length of the preprocessed data block is greater than or equal to the preset threshold. Since the filling operation is performed, the receiving end can remove the filling content to obtain the information data block, thereby reducing the complexity. For example, the information data block may be filled, or the information data block and the CRC are first padded with 0 to a certain length (greater than or equal to the preset threshold value), and then the preprocessed data block is obtained, and then the channel coding is performed, and then The receiving end transmits a signal.

需要说明的是，该实施方式中，预处理可以包括多种实施方式，这样可以在协议中预先定义，或者发送端与接收端预先协商采用哪种预处理方式，这样可以避免采用额外的信令来指示采用的预处理方式，以节约信令开销。当然，发送端也可以是根据实际情况灵活选择预处理方式，并通过显式或者隐式方式来通知接收端，以提高灵活性。It should be noted that, in this implementation manner, the pre-processing may include multiple implementation manners, which may be predefined in the protocol, or the pre-processing manner pre-negotiated by the transmitting end and the receiving end, so that additional signaling may be avoided. To indicate the pre-processing method used to save signaling overhead. Of course, the sending end can also flexibly select the preprocessing mode according to the actual situation, and notify the receiving end by explicit or implicit manner to improve flexibility.

其中，包括t个所述CRC和t个所述信息数据块可以理解为，包括t个重复内容，每个重复内容均为上述CRC和上述信息数据块。而上述包括t个所述信息数据块和所述CRC可以理解为，包括t个重复内容和一个CRC内容，每个重复内容均为上述信息数据块。以及上述对所述信息数据块进行重复操作，加上CRC可以是，对上述信息数据块进行重复操作后，再添加CRC，以得到包括所述CRC和t个所述信息数据块的目标比特。Wherein, including the t CRC and the t information data blocks may be understood to include t repeated content, each of which is the CRC and the information data block. The above-mentioned t data block and the CRC may be understood to include t repeated content and one CRC content, and each of the duplicate contents is the above information data block. And repeating the operation of the information data block, and adding the CRC may be, after performing the repeated operation on the information data block, adding a CRC to obtain a target bit including the CRC and the t information data blocks.

该实施方式中，可以实现若经过重复操作后，得到目标比特小于上述预设门限值，则可以将目标比特中的k个比特再次重复，以得到长度大于或者等于上述预设门限值的预处理数据块。可选的，上述k比特为上述目标比特中开始的k比特，如第1至第k个比特，当然，对此不作限定，例如：还可以是结尾的k比特等等。可选的，上述t可以是等于上述预设门限值除以M得到向下取整的整数或者0，其中，M等于上述信息数据块的长度，或者上述M等于上述信息数据块与CRC的长度之和。例如：上述预设门限值X等于50，则上述M等于16，则上述t等于3(50除以16向下取整等于3)，即t等于3，重复2次，得到48比特，再将2比特再次重复，得到50比特。In this embodiment, if the target bit is less than the preset threshold after the repeated operation, the k bits in the target bit may be repeated again to obtain a length greater than or equal to the preset threshold. Preprocess the data block. Optionally, the k-bit is the first k-bit in the target bit, such as the first to the k-th bit. Of course, the k-bit is not limited, for example, it may be the last k-bit or the like. Optionally, the foregoing t may be an integer equal to or greater than the preset threshold value divided by M, or 0, where M is equal to the length of the information data block, or the foregoing M is equal to the information data block and the CRC. The sum of the lengths. For example, if the preset threshold X is equal to 50, then the above M is equal to 16, then the above t is equal to 3 (50 divided by 16 is rounded down to 3), that is, t is equal to 3, repeated 2 times, and 48 bits are obtained, and then The 2 bits are repeated again to obtain 50 bits.

该实施方式中，由于仅是将k个比特再次重复，而不是整体重复一次，从而可以降低重复的工作量，因为，将这k个比特重复，就可以得到长度大于或者等于上述预设门限值的预处理数据块。例如：对M长的信息数据块，加上CRC，然后进行预处理，采用重复方式，如果t×M<＝X，则重复t－1次，也就是说包括t个重复比特，并且把开始的X－t×M个比特再次重复，以得到长度大于或者等于上述预设门限值的预处理数据块。In this embodiment, since only k bits are repeated again instead of being repeated once, the repeated workload can be reduced, because by repeating the k bits, the length is greater than or equal to the preset threshold. The preprocessed data block of values. For example: for the M-length information data block, add CRC, and then perform pre-processing, using the repetition mode. If t×M<=X, repeat t-1 times, that is to say include t repeated bits, and start The X-t×M bits are repeated again to obtain a pre-processed data block whose length is greater than or equal to the above-mentioned preset threshold value.

作为一种可选的实施方式，所述发送端显式指示或者隐式指示所述信息数据块在信道编码前经过所述预处理。As an optional implementation manner, the sending end explicitly indicates or implicitly indicates that the information data block passes the pre-processing before channel coding.

其中，上述显式指示可以是发送端向接收端发送一消息，在该消息中指示上述信息数据块在信道编码前经过了上述预处理。而上述隐式指示可以是不需要通过额外的消息来指示信息数据块在信道编码前经过了上述预处理，则是通过发送端向接收端发送的步骤202中的信号来指示，以降低传输开销。The explicit indication may be that the sending end sends a message to the receiving end, and in the message, the information data block is instructed to undergo the foregoing pre-processing before channel coding. The above implicit indication may be that the additional information is not required to indicate that the information data block has undergone the foregoing pre-processing before channel coding, and is indicated by the signal in step 202 sent by the transmitting end to the receiving end to reduce the transmission overhead. .

可选的，该实施方式中，所述显式指示包括：Optionally, in this implementation manner, the explicit indication includes:

通过DCI指示所述信息数据块在信道编码前经过所述预处理。The information data block is indicated by DCI to undergo the pre-processing before channel coding.

该实施方式中，可以实现通过DCI中的比特来指示信息数据块在信道编码前经过所述预处理。例如：在DCI中新增加几个比特新字段、或者重新定义DCI中的某些比特，使用这些比特来指示信息数据块在信道编码前经过所述预处理。In this embodiment, it may be implemented by the bits in the DCI to indicate that the information data block passes the pre-processing before channel coding. For example, a new bit field new field is added in the DCI, or some bits in the DCI are redefined, and these bits are used to indicate that the information data block passes the pre-processing before channel coding.

可选的，所述DCI还用于指示所述预处理的标识信息。例如：指示上述预处理的编号，例如：重复操作、编码操作或者填充操作的编号，以灵活使用预处理方式，以及通知接收端，以提高灵活性。当然，上述预处理也可以是预先定义好的，从而不需要DCI中指示其标识信息。Optionally, the DCI is further used to indicate the identifier information of the pre-processing. For example: indicating the number of the above pre-processing, for example: the number of repeated operations, encoding operations or padding operations, to flexibly use the pre-processing method, and to notify the receiving end to improve flexibility. Of course, the above pre-processing can also be predefined, so that the identification information in the DCI is not required.

可选的，在所述预处理包括重复操作的情况下，所述DCI还用于指示所述重复操作的重复次数。这样可以实现让接收端准确地进行相应的反操作，得到信息数据块。当然，本公开实施例中并不限定通过上述DCI来指示重复操作的重复次数，例如：还可以通过预处理数据块的长度来指示重复操作的重复次数，或者预先约定好等。Optionally, in the case that the pre-processing includes a repetitive operation, the DCI is further used to indicate the number of repetitions of the repeated operation. In this way, the receiving end can accurately perform the corresponding reverse operation to obtain the information data block. Certainly, the number of repetitions of the repeated operation is not limited by the above DCI in the embodiment of the present disclosure. For example, the number of repetitions of the repeated operation may be indicated by preprocessing the length of the data block, or may be agreed in advance.

可选的，所述隐式指示包括：Optionally, the implicit indication includes:

例如：通过上述预处理数据块的长度小于某一给定门限值Y，则表示信息数据块在信道编码前经过所述预处理。比如：根据编码后的上述预处理数据块的长度和指定的编码码率计算出的预处理数据块长度小于给定的Y，则表示信息数据块在信道编码前经过所述预处理。For example, if the length of the pre-processed data block is less than a given threshold value Y, it means that the information data block passes the pre-processing before channel coding. For example, if the length of the preprocessed data block calculated according to the length of the encoded preprocessed data block and the specified coded rate is less than a given Y, the information data block is subjected to the preprocessing before channel coding.

该实施方式中，由于通过上述预处理数据块的长度来隐指示信息数据块在信道编码前经过所述预处理，从而可以降低传输开销。In this embodiment, since the pre-processing of the information data block before the channel coding is implicitly indicated by the length of the pre-processed data block, the transmission overhead can be reduced.

可选的，在所述预处理包括重复操作的情况下，所述隐式指示还包括：通过所述预处理数据块的长度指示所述重复操作的重复次数。Optionally, if the pre-processing includes a repetitive operation, the implicit indication further includes: indicating, by using a length of the pre-processed data block, a repetition quantity of the repeated operation.

例如：预先定义一系列的值Y1，Y2，Y3……，当预处理数据块的比特数大于Y1，且不大于Y2时，接收端认为重复了一次，当预处理数据块的比特数大于Y2，且不大于Y3时，接收端认为重复了两次，当预处理数据块的的比特数大于Y3时，接收端认为重复了三次，等等。For example, a series of values Y1, Y2, Y3, ... are defined in advance. When the number of bits of the preprocessed data block is greater than Y1 and is not greater than Y2, the receiving end considers that it is repeated once, when the number of bits of the preprocessed data block is greater than Y2. When the value is not greater than Y3, the receiving end considers that it is repeated twice. When the number of bits of the preprocessed data block is greater than Y3, the receiving end considers that it is repeated three times, and so on.

由于通过预处理数据块的长度能够指示重复次数，从而不需要增加额外的消息来指示，以降低传输开销。当然，本公开实施例中，还可以通过其他隐式方式来指示重复次数，例如：通过业务类型，或者传输资源来指示重复次数。Since the number of repetitions can be indicated by the length of the pre-processed data block, there is no need to add an additional message to indicate to reduce the transmission overhead. Certainly, in the embodiment of the present disclosure, the number of repetitions may also be indicated by other implicit manners, for example, by the service type, or by transmitting resources to indicate the number of repetitions.

另外，需要说明的是，本公开实施例中，填充数量、填充数值以及编码率均可以通过隐式指示给接收端，或者还可以是协议中预先定义，或者发送端与接收端预先协商等方式确定，对此不作限定。In addition, it should be noted that, in the embodiment of the present disclosure, the number of padding, the padding value, and the coding rate may be implicitly indicated to the receiving end, or may be pre-defined in the protocol, or pre-negotiated between the transmitting end and the receiving end. Ok, there is no limit to this.

另外，本公开实施例介绍的多种可选的实施方式均可以独立实现，也可以相互结合实现，对此不作限定。In addition, the various optional embodiments introduced in the embodiments of the present disclosure may be implemented independently or in combination with each other, which is not limited thereto.

Of course, in the embodiment of the present disclosure, only the 16-bit CRC is used for illustration, which is not limited thereto.

404、检查发送缓存器中需要发送的数据量M，如果M>K，则从缓存器中取出K，剩余的下次传输，并进行后续操作，如果M<K，则进行以下操作。404. Check the amount of data M to be sent in the transmission buffer. If M>K, take K from the buffer, and the remaining next transmission, and perform subsequent operations. If M<K, perform the following operations.
