Description

Information processing method and device, and information transmission method and device

[0001] The present application claims priority from the Chinese patent application No. 202411378047.1 filed on September 29, 2024, and entitled "Information processing method, information transmission method and device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, in particular to an information processing method, an information transmission method and a device. BACKGROUND

[0003] In digital communication, a digital signal needs to be converted into a physical signal before being transmitted in a channel. The physical layer coding is used to encode the digital signal into the physical signal, which includes transport block (TB) attachment cyclic redundancy check (CRC), TB segmentation to obtain code block (CB), CB attachment CRC, channel coding, bit selection, bit interleaving, code block connection, scrambling, modulation and resource mapping, etc. Bit interleaving is a process of rearranging bits in a bit stream to randomize errors. By bit interleaving, the burst error of the channel is spread in time, avoiding concentrated bit transmission errors, which causes the receiving end to be completely unable to decode, so that the decoder can treat the above errors as random errors.

[0004] Currently, bit interleaving only considers the interleaving between bits within a single CB. When a CB includes transmission services with different transmission requirements, if the current interleaving method is still used for processing, it will make some services with special requirements unable to be completely transmitted, resulting in the receiving end being unable to decode. SUMMARY

[0005] Based on this, the present application provides an information processing method, an information transmission method and a device to realize reliable transmission of different services.

[0006] In the first aspect of the present application, an information processing method is provided, which comprises: determining first data and second data in a transport block; determining at least one first code block corresponding to the first data and at least one second code block corresponding to the second data; and jointly interleaving the at least one first code block and the at least one second code block. Based on the technical solution provided in the present application, for different data carried in a transport block, such as the first data and the second data, at least one code block corresponding to each data is determined, i.e. at least one first code block corresponding to the first data and at least one second code block corresponding to the second data. The at least one first code block corresponding to the first data and the at least one second code block corresponding to the second data are jointly interleaved, so as to realize the interleaving between the code blocks. That is, when bit interleaving is implemented, the present application considers the requirement for complete and reliable data transmission, and performs interleaving between the code blocks corresponding to the data with complete transmission requirement, so as to improve the data transmission reliability and guarantee the complete and reliable data transmission.

[0007] In some embodiments, the at least one first code block corresponding to the first data and the at least one second code block corresponding to the second data can be determined by: determining the number of the first code blocks corresponding to the first data according to the number of bits occupied by the first data in the transport block and the number of bits included in a code block; and determining the number of the second code blocks corresponding to the second data according to the number of bits occupied by the second data in the transport block and the number of bits included in a code block.

[0008] The first data and the second data can be different data corresponding to the same transmission service, or can be data corresponding to different transmission services. The transmission service can include services with different transmission reliabilities, such as services with 100% transmission reliability and services with 80% transmission reliability.

[0009] The transmission type of the transmission service can include fault-tolerant services and non-fault-tolerant services. The fault-tolerant service means that part of the information is allowed to be transmitted incorrectly during the transmission process, and the non-fault-tolerant service means that no information is allowed to be transmitted incorrectly during the transmission process. Specifically, the first data can be data corresponding to a non-fault-tolerant service, and the second data can be data corresponding to a fault-tolerant service.

[0010] When the at least one first code block and the at least one second code block are jointly interleaved, the first code block and the second code block can be interleaved according to a preset joint interleaving rule. The joint interleaving rule is used to indicate that the joint interleaving is performed according to the transmission requirements of the first data and the second data. The transmission requirements can include transmission reliability, security, etc.

[0011] The first data can be replaced by a first feature, i.e. the information carried by the first data represents the content of the first feature.

[0012] If the transmission requirement of the first data is higher than that of the second data, for example, the first data is non-fault-tolerant service and the second data is fault-tolerant service, the transmission reliability of the first data is higher than that of the second data. In this case, when the first code block and the second code block are jointly interleaved according to the joint interleaving rule, the first number of bits occupied by the first code block and the second number of bits occupied by the second code block in the modulation symbol are determined according to the allocation ratio and the modulation symbol. Since the transmission requirement of the first data is higher than that of the second data, the first number of bits before the modulation symbol carries the first code block, and the second number of bits after the modulation symbol carries the second code block. That is, the high bits of the modulation symbol carry the first code block, and the low bits carry the second code block.

[0013] In some embodiments, in order to enable the receiving end to know the correspondence between different data and code blocks, the sending end can send indication information for indicating the correspondence between the first data and the at least one first code block, and / or the correspondence between the second data and the at least one second code block. That is, the sending end informs the receiving end of the distribution of the first code block corresponding to the first data and / or the distribution of the second code block corresponding to the second data by sending the indication information, so that the receiving end can perform differential processing according to the transmission requirements of different data when receiving the first data and the second data.

[0014] The indication information can be downlink control information (DCI) or a medium access control (MAC) control element. The specific form of the indication information is related to the distribution of the first code block and the second code block in the transport block, and specifically includes:

[0015] If the first code block and the second code block are sequentially arranged in the transport block, the indication information is used to indicate the number of the first code blocks and / or the number of the second code blocks in the transport block. Sequential arrangement means that all the first code blocks are arranged adjacently and all the second code blocks are arranged adjacently. The first code blocks can be arranged first and the second code blocks can be arranged later, or the second code blocks can be arranged first and the first code blocks can be arranged later.

[0016] If the first code block and the second code block are not sequentially arranged in the transport block, the indication information is used to indicate the distribution position of the at least one first code block in the transport block and / or the distribution position of the at least one second code block in the transport block.

[0017] In the second aspect of the present application, an information transmission method is provided, which comprises: determining first data and second data in a transport block;

[0018] determining at least one first code block corresponding to the first data in the transport block and / or at least one second code block corresponding to the second data; and sending indication information indicating a correspondence between the first data and the at least one first code block and / or a correspondence between the second data and the at least one second code block. Through the scheme, the mapping relationship between different data and CBs is indicated by the sending end, so that the receiving end can perceive the correspondence between different CBs and data in the TB, and differential upward submission can be realized. Specifically, the CB corresponding to the non-fault-tolerant data is not submitted when receiving an error, and the CB corresponding to the fault-tolerant data is submitted upward.

[0019] In a possible implementation, the determining of the at least one first code block corresponding to the first data and / or the at least one second code block corresponding to the second data includes: determining a number of the first code blocks corresponding to the first data according to a number of bits occupied by the first data in the transport block and a number of bits included in a code block; and determining a number of the second code blocks corresponding to the second data according to a number of bits occupied by the second data stream in the transport block and a number of bits included in a code block.

[0060] To facilitate understanding of the technical solutions provided by the present application, the technical background involved by the present application will be described first.

[0061] The current interleaving solution is performed for a CB as granularity, i.e., inter-CB interleaving. In specific implementation, a row-column interleaver can be used to respectively interleave each CB after rate matching, and independent interleaving of each CB can reduce latency and UE complexity. As shown in Fig. 1a, the number of rows of the interleaver is the modulation order, such as 64 Quadrature Amplitude Modulation (QAM) equal to 6. When the length of a CB is 6000 bits (for example), a data with a length of 6 rows * 1000 columns is constructed, which is written in a row-by-row manner, but read in a column-by-column manner.

[0062] After interleaving is completed, modulation needs to be performed, that is, the read bits are mapped to symbols. Since different bits have different transmission reliabilities after being mapped to symbols, the above interleaving scheme itself performs bit priority mapping. Taking 256QAM as an example, since the reliabilities of the bits in a QAM modulation symbol are different, for example, a 256QAM modulation symbol corresponds to 8 bits, the reliabilities of the first 2 bits are the highest, the reliabilities of the 3rd and 4th bits are the second highest, the reliabilities of the 5th and 6th bits are the third highest, and the reliabilities of the last two bits are the lowest.

[0063] As known from the above, the existing physical layer encoding interleaving only considers the CB-in interleaving scheme. If multiple CBs in a single TB simultaneously exist different services, the physical layer interleaving does not consider the differentiated requirements of different services on transmission reliability, resulting in that the service transmission reliability cannot be met. For example, when a single TB simultaneously exists a fault-tolerant service and a non-fault-tolerant service, the existing interleaving does not consider the differentiated demands of different services on transmission integrity, that is, the non-fault-tolerant service needs complete transmission, and the fault-tolerant feature can be correctly transmitted, but the non-fault-tolerant feature cannot be correctly transmitted.

[0064] Based on this, the present application proposes an information processing method, CB interleaving based on feature granularity, that is, determining at least one first code block corresponding to first data and at least one second code block corresponding to second data included in a transport block, performing joint interleaving on the at least one first code block and the at least one second code block to realize code block interleaving. Wherein, the feature refers to if the transmission requirements of two data are different, the two data correspond to different features.

[0065] In addition, a downlink data transmission procedure between the network device and the terminal device is shown in FIG. 1b. Data transmission needs to pass through user plane protocol layers of the network device, such as a service data adaptation protocol (SDAP) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, a medium access control (MAC) layer, and a physical layer. The SDAP layer, the PDCP layer, the RLC layer, the MAC layer, and the physical layer can also be collectively referred to as an access layer. According to the transmission direction of data, each layer is divided into a sending part (downward arrow in the figure) and a receiving part (upward arrow in the figure). In the protocol, the correspondence between layers is mostly in the form of a channel. The RLC layer and the MAC layer are corresponded through a logical channel (LCH), the MAC layer and the physical layer are corresponded through a transport channel, and the physical layer below is a physical channel, which is used to correspond to the physical layer of the other end.

[0066] The SDAP layer is responsible for mapping a session from an upper layer to a radio bearer in a lower layer. The radio bearer mainly includes a PDCP entity and an RLC entity. The PDCP entity is located in the PDCP layer. After obtaining data from the upper layer, the PDCP entity transmits the data to the RLC layer and the MAC layer, and then the MAC layer generates a transport block (TB) and transmits the TB through the physical layer for wireless transmission. Data is encapsulated in each layer. Data received by a layer from an upper layer of the layer is regarded as a service data unit (SDU) of the layer. After layer encapsulation, the data becomes a protocol data unit (PDU) and is transmitted to a next layer. For example, data received by the PDCP layer from an upper layer is referred to as a PDCP SDU, and data transmitted by the PDCP layer to a lower layer is referred to as a PDCP PDU. Data received by the RLC layer from an upper layer is referred to as an RLC SDU, and data transmitted by the RLC layer to a lower layer is referred to as an RLC PDU. Data received by the MAC layer from an upper layer is referred to as a MAC SDU, and data transmitted by the MAC layer to a lower layer is referred to as a MAC PDU. The MAC PDU can also be referred to as a transport block (TB).

[0067] The MAC layer transmits the TB to the physical layer, the physical layer adds CRC to the TB, and divides the TB with added CRC into a plurality of CBs according to a certain rule, and then adds CRC to each CB, so that the CBs are checked at the receiving end to obtain correct CBs. As shown in FIG. 1c, one TB is divided into three CBs, CB1, CB2 and CB3, and each CB has corresponding CRC added thereto.

[0068] Since the network device can simultaneously carry transmission data of different services in one TB when transmitting data to the terminal device, the receiving end cannot perform differential decoding processing due to the absence of the correspondence between different services and CBs, thereby affecting the data transmission efficiency. For example, when there are fault-tolerant services and non-fault-tolerant services in a single TB, the sending end does not indicate the distribution of the TB content fault-tolerant services and non-fault-tolerant services on the CBs, so that the physical layer of the receiving end cannot perform differential submission to the application layer.

[0069] Based on this, the present application provides an information transmission method, for at least one first code block corresponding to first data in a transmission block and at least one second code block corresponding to second data, sending indication information to a receiving end, the indication information indicating the correspondence between the first data and the at least one first code block and the correspondence between the second data and the at least one second code block. In this way, the receiving end can perform decoding processing on different features based on the above correspondence. For example, the receiving end can perceive the correspondence between different CBs in the TB and fault-tolerant services and non-fault-tolerant services, and implement differential submission to the upper layer, that is, non-fault-tolerant services do not submit errors to the upper layer, and fault-tolerant services submit to the upper layer.

[0070] The fault-tolerant service refers to allowing part of the information to be transmitted with errors in the transmission process. Specifically, it refers to that the application layer is based on multi-feature encoding, and when part of the features are transmitted with errors, the decoding and recovery of the application layer can also be completed. The non-fault-tolerant service refers to not allowing any information to be transmitted with errors in the transmission process, otherwise the correct content recovery cannot be performed based on the erroneous data.

[0071] The technical solution of the present application can be applied to various communication systems, such as a 5G or new radio (NR) system, a long term evolution (LTE) system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD) system, etc.

[0072] The communication system architecture of the present application is shown in Figure 2a. The communication system comprises a radio access network, and optionally, a core network and an Internet. The radio access network can comprise at least one radio access network device, and can further comprise at least one terminal device. The terminal device is connected to the radio access network device in a wireless manner, and the radio access network device is connected to the core network in a wireless or wired manner. The core network device and the radio access network device can be independent and different physical devices, or can be integrated into the same physical device with the functions of the core network device and the logical functions of the radio access network device, or can be a physical device integrated with part of the functions of the core network device and part of the functions of the radio access network device. The terminal device and the terminal device, and the radio access network device and the radio access network device can be connected to each other in a wired or wireless manner.

Terminal devices are usually provided with communication modules, circuits or chips for executing corresponding communication functions, and terminal devices are also configured with program instructions for executing corresponding communication functions.

[0074] It should be noted that the terminal device can be a device or apparatus with a chip, or a device or apparatus integrated with a circuit, or a chip, chip system, module or control unit in the above-mentioned devices or apparatus, and the specific application is not limited.

For example, a fourth-generation (4G) mobile communication system, a 5G mobile communication system, or a 6G mobile communication system. The access network device can also be an access network device in an open radio access network (O-RAN or ORAN) or a cloud radio access network (CRAN).

[0087] The technical solutions provided by the present application will be described below in conjunction with specific embodiments. For ease of understanding, the network device is taken as the sending end and the terminal device is taken as the receiving end for description.

[0088] Referring to FIG. 3, the information processing method provided by the embodiment of the present application, as shown in FIG. 3, comprises the following steps:

[0089] S301: determining first data and second data in a transmission block.

[0090] The first data can be a non-fault-tolerant service, and the second data can be a fault-tolerant service. Different data correspond to different features, so the first data can correspond to a first feature, and the second data corresponds to a second feature. The feature refers to the data information corresponding to the transmission service. For example, when a video is transmitted, the feature can refer to information describing the shape of the object in the video, the spatial relationship between the objects, and the event content of the object, etc. This information can also be referred to as semantic features.

[0091] In this embodiment, one transmission block can transmit multiple types of data at the same time, or can transmit multiple features. The multiple features include a first feature and a second feature. The first feature and the second feature can be different features corresponding to the same transmission service. For example, when a video is transmitted, one video frame can be divided into multiple slices Slice, and each Slice can be regarded as a feature, i.e., one video frame corresponds to multiple features, which are described by multiple features. The multiple features can be independent or have correlation. Or the first feature and the second feature are features corresponding to different transmission services, for example, the first feature is a feature of a voice service, and the second feature is a feature of a video service. Specifically, it can be determined according to the information carried in the transmission block which types of data are included in the transmission block.

[0092] The transmission type of the transmission service can include fault-tolerant services and non-fault-tolerant services. That is, fault-tolerant services and non-fault-tolerant services can be transmitted in one transmission block at the same time. For example, the first data can be data corresponding to a non-fault-tolerant service, and the second data can be data corresponding to a fault-tolerant service.

[0093] S302: determine at least one first code block corresponding to the first data and at least one second code block corresponding to the second data.

[0094] After determining the different data included in the transport block, the code block corresponding to each data is determined. That is, at least one first code block corresponding to the first data and at least one second code block corresponding to the second data are determined. It should be noted that the information carried by the first code block all belongs to the first data, and the information carried by the second code block all belongs to the second data. That is, only one type of data is carried on one code block.

[0095] When segmenting the transport block, it is currently segmented according to the TB size and the fixed size of the CB, as shown in formula (1):

[0096] Wherein, B is the number of bits in the TB, Kcb is the number of bits that the CB can contain, L is the length of the CRC, and C is the number of segmented CBs, that is, the number of CBs corresponding to the first data.

[0097] If the segmentation is performed according to formula (1), different features can fall into the same CB, that is, one code block can carry multiple different data. In order to avoid different data being segmented into the same code block, the embodiment provides a segmentation method, that is, according to the number of bits occupied by the first data in the transport block and the number of bits included in the code block, the number of first code blocks included in the first data is determined; and according to the number of bits occupied by the second data stream in the transport block and the number of bits included in the code block, the number of second code blocks included in the second data is determined. That is, when the TB is segmented, the segmentation is performed according to the granularity of different data, so that different data is segmented into different code blocks. For details, see formula (2):

[0098] Wherein, B1 represents the number of bits occupied by data 1 in the TB, C1 represents the number of CBs occupied by data 1, Kcb is the number of bits that the CB can contain, and L is the length of the CRC.

[0099] That is, for the first data and the second data, a group of CBs corresponding to itself can be determined by formula (2) respectively. Among them, the first data corresponds to a group of CBs including C1 CBs, and the second data corresponds to a group of CBs including C2 CBs.

[0100] If different data are sequentially distributed in the transport block, for example, a TB sequentially distributes data 1, data 2 and data 3. For this case, for any data, CB segmentation is performed according to formula (2), so that the same data can be segmented into one CB, and different data are segmented into different CBs. If different data are cross-distributed in the transport block, for example, a TB distributes data 1 part 1, data 2 part 1, data 1 part 2, data 3 part 1, data 2 part 2 and data 3 part 2. For this case, the data in the transport block is first rearranged so that the same data can be distributed adjacently after rearrangement (i.e., the rearranged data are sequentially distributed), and then segmentation is performed using formula (2). For example, after rearrangement, the distribution is data 1 part 1, data 1 part 2, data 2 part 1, data 2 part 2, data 3 part 1 and data 3 part 2.

[0101] S303: Joint interleaving of the at least one first code block and the at least one second code block.

[0102] In this embodiment, after determining the code block corresponding to each data, joint interleaving between the code blocks corresponding to different data is implemented, and the interleaving is not within the code block.

[0103] In the joint interleaving of the at least one first code block and the at least one second code block, the joint interleaving can be randomly performed, or a joint interleaving rule can be pre-configured or defined to implement interleaving between the code blocks according to the joint interleaving rule. The joint interleaving rule is used to indicate that the joint interleaving between the code blocks can be performed according to the transmission requirements of different characteristics, which can include one or more of real-time performance, reliability, bandwidth, flexibility, security, etc. Since the existing bit interleaving, when mapped to the modulation symbol, the symbols at different positions themselves have different reliability differences, in order to guarantee the reliability requirement of certain services (such as non-fault-tolerant services), the code block corresponding to the service can be mapped to the reliable constellation of the modulation symbol.

[0104] Specifically, if the transmission requirement of the first data is higher than the transmission requirement of the second data, when the at least one first code block and the at least one second code block are jointly interleaved according to the joint interleaving rule, the first number of bits occupied by the first code block and the second number of bits occupied by the second code block on the modulation symbol can be determined according to the allocation ratio and the modulation symbol. Wherein, the first number of bits of bit positions corresponding to the modulation symbol bear the first code block, and the second number of bits of bit positions corresponding to the modulation symbol bear the second code block. That is, when the transmission requirement of the first data is higher than the transmission requirement of the second data, the bit positions with high reliability in the modulation symbol are used to bear the first code block, and the bit positions with low reliability in the modulation symbol are used to bear the second code block. For example, the first data is a non-fault-tolerant service feature, and the second data is a fault-tolerant service feature. The above joint interleaving rule can guarantee the reliable transmission of the non-fault-tolerant feature.

[0105] Wherein, the allocation ratio is used to indicate the ratio of the first code block and the second code block on one modulation symbol. In specific implementation, the allocation ratio can be pre-configured or pre-defined, or the allocation ratio can be the transmission ratio of the code block corresponding to the first data and the second data in the transmission block. For example, the transmission ratio of non-fault-tolerant service and fault-tolerant service in a single TB is 2:1, and the allocation ratio of CB joint interleaving can be 2:1. If 64QAM transmission mode is adopted, a single transmission symbol corresponds to 6 bits, and the first 4 bits can be used to transmit the CB corresponding to the non-fault-tolerant service, and the last 2 bits can be used to transmit the CB corresponding to the fault-tolerant service. For example, as shown in FIG. 4, one row corresponds to one CB, the first 4 rows respectively correspond to 4 CBs corresponding to the non-fault-tolerant service, and the last 2 rows respectively correspond to 2 CBs corresponding to the fault-tolerant service.

[0106] Another possible way is that the first data and the second data form a third data, the first data is in front, and the second data is in back. The third data is interleaved according to the rule of the row-column interleaver, and the first data can also be mapped to the reliable bits in a symbol to achieve reliable transmission of the first data.

[0107] In order to enable the receiving end to distinguish the CB corresponding to different data, the sending end can also send indication information to the receiving end, the indication information being used to indicate the corresponding relationship between the first data and the at least one first code block, and / or the corresponding relationship between the second data and the at least one second code block.

[0108] Specifically, in order to reduce the occupation of transmission resources, the indication information can only indicate the corresponding relationship between a certain data and the code block corresponding thereto. In this way, the receiving end can determine which code blocks in the transmission block correspond to the first data and which code blocks correspond to the second data according to the indication information after receiving the indication information and the transmission block.

[0109] The indication information can be DCI or a MAC control element. That is, the indication information can be carried in the form of DCI or in a MAC control element when the transport block is transmitted.

[0110] In a specific implementation, the specific form of the indication information can be determined according to the arrangement of the first code blocks and the second code blocks in the transport block. Specifically, if the first code blocks and the second code blocks are sequentially arranged in the transport block, the indication information is used to indicate the number of the first code blocks and / or the number of the second code blocks in the transport block. Sequential arrangement means that all the first code blocks are arranged adjacently and all the second code blocks are arranged adjacently. The first code blocks can be arranged first and the second code blocks can be arranged later, or the second code blocks can be arranged first and the first code blocks can be arranged later.

[0111] For example, a TB includes 9 CBs, the first data occupies 6 CBs and the second data occupies 3 CBs, the first data is in front and the second data is at the back, the indication information can be that the first data occupies the first 6 CBs, or the indication information can be that the second data occupies the last 3 CBs. For another example, as shown in FIG. 5a, the first data is fault-tolerant data occupying 6 CBs and the second data is non-fault-tolerant data occupying 3 CBs, the fault-tolerant data is in front and the non-fault-tolerant data is at the back. In this case, the indication information can be that the fault-tolerant data occupies the first 6 CBs, or the indication information can be that the non-fault-tolerant data occupies the last 3 CBs.

[0112] If the first code blocks and the second code blocks are not sequentially arranged in the transport block, the indication information indicates the distribution positions of at least one first code block in the transport block or the distribution positions of at least one second code block in the transport block. For example, as shown in FIG. 5b, the first data is fault-tolerant data and is distributed at positions 1 / 2 / 3 / 4 / 6 / 7 in the transport block, and the second data is non-fault-tolerant data and is distributed at positions 5 / 8 / 9 in the transport block. In this case, the indication information can directly include the distribution position sequence numbers index of the fault-tolerant data, which are {1 / 2 / 3 / 4 / 6 / 7}, or the indication information can directly include the distribution position sequence numbers index of the non-fault-tolerant data, which are {5 / 8 / 9}.

[0113] Alternatively, to reduce the content carried by the indication information, the indication information can not carry specific distribution position sequence numbers, but can carry an identifier corresponding to multiple distribution position sequence numbers. For example, the first data is distributed at positions 1 / 2 / 3 / 4 / 6 / 7 in the transport block, and the indication information carries an identifier P1 corresponding to {index=1 / 2 / 3 / 4 / 6 / 7}. Alternatively, the indication information carries an identifier P2 corresponding to {index=5 / 8 / 9}.

[0114] The sending end defines the mapping relationship between different data and CBs, so that the receiving end can perceive the corresponding relationship between different CBs and data in the TB, and can realize differentiated upward submission. Specifically, the CB corresponding to the non-fault-tolerant data is not submitted when receiving errors, and the CB corresponding to the fault-tolerant data is submitted upward.

[0115] Referring to FIG. 6, which is a flowchart of an information transmission method provided by an embodiment of the present application, as shown in FIG. 6, the method can include:

[0116] S601: determining first data and second data in a transport block.

[0117] S602: determining at least one first code block included by the first data in the transport block, and / or at least one second code block included by the second data.

[0118] In the present application, the transport block can include multiple data, which can include first data and second data. The first data and the second data can be different data corresponding to the same transmission service, or can be data corresponding to different transmission services, which are not limited in the present embodiment. The transmission type of the transmission service can include fault-tolerant service and non-fault-tolerant service. That is, the fault-tolerant service and the non-fault-tolerant service can be transmitted in one transport block, for example, the first data can be data corresponding to the non-fault-tolerant service, and the second data can be data corresponding to the fault-tolerant service.

[0119] Specifically, when determining the number of code blocks corresponding to different data in the transport block, the number of bits occupied by one data in the transport block and the number of bits included by one code block can be used for determination. Specifically, according to the number of bits occupied by the first data in the transport block and the number of bits included by the code block, the number of first code blocks included by the first data is determined. And / or, according to the number of bits occupied by the second data stream in the transport block and the number of bits included by the code block, the number of second code blocks included by the second data is determined. For specific implementation of determining at least one first code block included by the first data or at least one second code block, please refer to the related description of S302 above.

[0120] It should be noted that when the transport block only includes the first data and the second data, the code blocks corresponding to one of the data can be determined, without determining the code blocks corresponding to all data, thereby reducing the calculation amount.

[0121] S603: sending indication information.

[0122] The indication information is used to indicate the corresponding relationship between the first data and the at least one first code block, and / or the corresponding relationship between the second data and the at least one second code block.

[0123] After determining the correspondence between the data in the transport block and the code blocks, the base station can send the correspondence to the terminal device by sending indication information, so that the terminal device can obtain which code blocks the data corresponds to, in order to perform differential processing according to the characteristics of different transmission types.

[0124] The indication information can be downlink control information (DCI) or a MAC control element. That is, the base station can carry the indication information in the form of sending DCI, or can carry the indication information in the MAC control element when sending the transport block.

[0125] In specific implementation, the specific form of the indication information can be determined according to the arrangement mode of the first code blocks and the second code blocks in the transport block. Specifically, if the first code blocks and the second code blocks are sequentially arranged in the transport block, the indication information is used to indicate the number of the first code blocks and / or the number of the second code blocks in the transport block. Sequential arrangement means that all the first code blocks are arranged adjacently and all the second code blocks are arranged adjacently. The first code blocks can be arranged first and the second code blocks can be arranged later, or the second code blocks can be arranged first and the first code blocks can be arranged later.

[0126] Alternatively, if the first code blocks and the second code blocks are non-sequentially arranged in the transport block, the indication information indicates the distribution position of at least one first code block in the transport block or the distribution position of at least one second code block in the transport block.

[0127] It should be noted that the specific form of the indication information can be referred to the related description in the embodiment described in FIG. 3.

[0128] It can be seen that, by defining the mapping relationship between different data and CBs, the receiving end can perceive the correspondence between different CBs and data in the TB, and differential submission to the upper layer is realized.
