Description

A communication method, communication device and storage medium

[0001] This application claims priority to Chinese Patent Application No. CN202411691732.X, filed on November 22, 2024, entitled "A Communication Method, Communication Device and Storage Medium", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, and in particular to a communication method, communication device and storage medium. Background Technology

[0003] In recent years, with the continuous development of the fifth generation (5G) communication system, data transmission latency has been continuously reduced and transmission capacity has been increasing. The 5G communication system has gradually penetrated into some multimedia services with strong real-time requirements and large data capacity requirements, such as video transmission, cloud gaming (CG), and extended reality (XR), among which XR includes virtual reality (VR) and augmented reality (AR).

[0004] Currently, to improve transmission rates, superposition transmission technology can be used. Superposition transmission is a coding scheme called block markov superposition transmission (BMST). The transmitting end divides the data block into multiple sub-blocks, such as code blocks (CBs), and encodes each sub-block using low-density parity check (LDPC) codes to obtain corresponding codewords. The previous codeword is superimposed on the current codeword, and the superimposed codeword is used as the actual codeword sequence to be transmitted. This method forms a sliding window-based chain superposition transmission. The receiving end then decodes the data using a sliding window-based decoding algorithm.

[0005] However, in physical layer data transmission, information is sent at the transport block (TB) granularity. If a TB is corrupted, it needs to be retransmitted. If the number of retransmitted TBs exceeds the packet delay budget (PDB), the retransmission is meaningless, thus affecting the transmission of data packets. Summary of the Invention

[0006] This application provides a communication method, communication device, and storage medium for implementing superposition coding between transport blocks.

[0007] The first aspect of this application provides a communication method. Optionally, the subject executing the method can be a transmitting device, which can be a network device, a component or device applied to the network device (e.g., a processor, circuit, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the network device (e.g., a central unit (CU), a distributed unit (DU), or a radio unit (RU)). The transmitting device can also be a terminal device, a component or device applied to the terminal device (e.g., a processor, circuit, chip, or chip system), or a circuit or chip in the terminal device responsible for communication functions (e.g., a modem chip, also known as a baseband chip, or a system-on-a-chip (SoC) chip containing a modem core, or a system-in-package (SIP) chip). In this method, the sending device determines first data, which includes a first code block.

The sending device sends a first data packet, which includes multiple data, and the multiple data include the first data.

[0008] Based on the first aspect of this application, since the first code block in the first data is obtained by superimposing data from multiple first transmission blocks, when a data transmission error occurs in the data packet, the receiving device can correct the erroneous data based on the first data in the data packet, thereby enabling the data in the data packet to be successfully decoded and improving the performance gain of mutual error correction between transmission blocks.

[0084] This application provides a communication method, communication device, and storage medium. Since the first code block in the first data is obtained by superimposing data from multiple first transmission blocks, when the data transmission in the data packet is erroneous, the receiving device can correct the erroneous data according to the first data in the data packet, thereby enabling the data in the data packet to be successfully decoded and improving the performance gain of mutual error correction between transmission blocks.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0087] References to "one embodiment" or "some embodiments" as described in this application mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0088] In the description of this application, unless otherwise stated, " / " means "or". For example, A / B can mean A or B. "And / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Furthermore, "at least one" means one or more, and "multiple" means two or more. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or multiple items. For example, at least one of a, b, or c can represent: a, b, c; a and b; a and c; b and c; or a and b and c. Where a, b, and c can be single or multiple.

[0089] In this application, "sending information" can be understood as one device sending information to another device, or it can also be understood as one logic module within a device sending information to another logic module. For example, "sending device sending information" can be understood as the sending device sending information to another device (such as the receiving device), or it can be understood as logic module 1 in the sending device sending information to logic module 2 in the sending device.

This can include receiving information directly or indirectly from the receiving device. Information may undergo necessary processing between the source and destination, such as format changes, but the destination can understand the valid information from the source. Similar expressions in this application can be interpreted similarly, and will not be elaborated further here.

[0092] First, some technical terms involved in the embodiments of this application will be introduced.

[0093] 1) TB and CB;

[0094] A TB (Block Byte) is a block of data transmitted within a TTI (Time Interval) or slot, representing a Medium Access Control Protocol (MAC) protocol data unit (PDU). For a TB to be transmitted, it undergoes code block segmentation and channel coding. The basic data unit processed in this process is the CB (Code Block), and the output data unit after sequential concatenation of CBs is the code word (CW). A TB can be divided into multiple CBs, and a CB can occupy multiple orthogonal frequency division multiplexing (OFDM) symbols, or multiple CBs can occupy one OFDM symbol. For the CW, after scrambling, modulation, layer mapping, antenna port mapping, and frequency domain resource mapping at the physical layer, its bit stream is mapped onto an OFDM symbol and transmitted through a physical antenna.

[0095] 2) Extended Reality (XR) technology:

[0096] XR technology is a new type of technology that combines computer-generated visual, auditory, and tactile information with the real world, making the interaction between humans and digital information more intuitive and natural. XR includes virtual reality (VR) and augmented reality (AR). With the rapid increase in communication transmission speed, real-time video transmission services have gradually become one of the core services in current networks. The continuous progress and improvement of extended reality technology has also led to the vigorous development of related industries. Today, VR technology, as a type of XR, has entered various fields closely related to people's production and life, such as education, entertainment, military, medical care, environmental protection, transportation, and public health. Compared with traditional video services, VR has advantages such as multiple perspectives and strong interactivity, providing users with a completely new visual experience. In addition to smartphones, people increasingly hope to enhance the XR experience through user equipment (UE) such as head-mounted displays (HMDs) or smart glasses (such as VR glasses and AR glasses). With increasingly stringent requirements for video transmission quality, and the further development of extended reality and the tactile internet, ensuring quality of experience (QoE) and quality of service (QoS) has become a key research focus.

[0097] 3) Overlay transmission technology:

[0098] Superposition transmission is a block markov superposition transmission (BMST) coding scheme. The transmitting end divides the data block into multiple sub-blocks and encodes each sub-block using low-density parity check (LDPC) codes to obtain corresponding codewords. The previous codeword is XORed with the current codeword, and the superimposed codeword is used as the actual transmitted codeword sequence. This method forms a sliding window-based chain superposition transmission. The receiving end device decodes the codewords using a sliding window-based decoding algorithm. Taking Figure 1 as an example, an information bit sequence u1 is encoded using LDPC to obtain a codeword sequence c1. Since it is the first codeword sequence, no superposition is needed, and the corresponding transmitted v1 sequence is the c1 sequence. Similarly, the information bit sequence u2 is encoded using LDPC to obtain a codeword sequence c2. By superimposing the previous codeword sequence c1 onto the bits of codeword sequence c2, the actual transmitted superimposed codeword sequence v2 is obtained. Similarly, u3 and u4 are processed in the same way to obtain the superimposed codeword sequences v3 and v4. Based on the maximum superimposed length, the corresponding superimposed transmission threshold is determined. For example, if a maximum of k information sequences are allowed to be superimposed and transmitted, then the maximum transmission length is uk, and the corresponding actual codewords transmitted are v1 to vk.

[0099] Please refer to Figure 2. The network architecture on which the communication method in this embodiment is based is briefly described below:

[0100] Figure 2 is a possible, non-limiting system schematic diagram. As shown in Figure 2, the communication system 10 includes an access network (RAN) 100, a core network (CN) 200, and the Internet. RAN 100 includes at least one RAN node (110a and 110b in Figure 2, collectively referred to as 110) and at least one terminal (120a-120j in Figure 2, collectively referred to as 120). RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment (not shown in Figure 2). Terminal 120 is wirelessly connected to RAN node 110. RAN node 110 is wirelessly or wired connected to core network 200. The core network equipment in core network 200 and RAN node 110 in RAN 100 can be different physical devices, or they can be the same physical device integrating core network logical functions and wireless access network logical functions.

[0101] RAN 100 can be a cellular system related to the 3rd Generation Partnership Project (3GPP), such as a 4G, 5G, or future mobile communication system. RAN 100 can also be an open-radio access network (ORAN), a cloud-radio access network (CRAN), or a Wi-Fi system. RAN 100 can also be a communication system that integrates two or more of the above systems.

[0102] RAN node 110, sometimes also referred to as access network equipment, RAN entity, or access node, constitutes part of the communication system and is used to help terminals achieve wireless access. Multiple RAN nodes 110 in communication system 10 can be of the same type or different types. In some scenarios, the roles of RAN node 110 and terminal 120 are relative. For example, network element 120i in Figure 2 can be a helicopter or drone, which can be configured as a mobile base station. For terminals 120j accessing RAN 100 through network element 120i, network element 120i is a base station; but for base station 110a, network element 120i is a terminal. RAN node 110 and terminal 120 are sometimes both referred to as communication devices. For example, network elements 110a and 110b in Figure 2 can be understood as communication devices with base station functions, and network elements 120a-120j can be understood as communication devices with terminal functions.

[0103] In one possible scenario, access network equipment includes, but is not limited to: evolved Node B (eNodeB), radio network controller (RNC), Node B (NB), base station (BS), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved NodeB, or home Node B, HNB), baseband unit (BBU), access point (AP) in wireless fidelity (WIFI) system, macro base station, micro base station, wireless relay node, donor node, radio controller in CRAN scenario, wireless backhaul node, transmission point (TP), or transmission and reception point (TRP), etc., and can also be access network equipment in 5G mobile communication system. For example, a next-generation NodeB (gNB), TRP, or TP in an NR system; or one or a group of antenna panels (including multiple antenna panels) in a base station in a 5G mobile communication system; or, access network equipment can also be network nodes constituting a gNB or transmission point. Examples include centralized units (CU), distributed units (DU), centralized unit control planes (CU-CP), centralized unit user planes (CU-UP), or radio units (RU), etc. CUs and DUs can be separate or included in the same network element, such as a BBU. RUs can be included in radio equipment or radio units. For example, in remote radio units (RRU), active antenna units (AAU), or remote radio heads (RRH). Alternatively, access network equipment can also be servers, wearable devices, vehicles, or in-vehicle equipment, etc. For example, the access network equipment in V2X technology can be a roadside unit (RSU).It should be understood that the aforementioned TRP can be a device or module located on the network side of the aforementioned communication system and possessing corresponding communication functions. The TRP typically contains a communication module, circuit, or chip that performs the corresponding communication functions. The TRP can also be configured with program instructions for the corresponding communication functions.

[0104] It should be noted that CU (or CU-CP and CU-UP), DU, or RU may have different names in different systems, but those skilled in the art will understand their meaning. For example, in an open radio access network (ORAN) system, CU can also be called an open centralized unit (O-CU) or an open CU, DU can also be called an open-distributed unit (O-DU), CU-CP can also be called an open-centralized unit control plane (O-CU-CP), CU-UP can also be called an open-centralized unit user plane (O-CU-UP), and RU can also be called an open radio unit (O-RU). This application does not limit the specific names. Any of the units CU, CU-CP, CU-UP, DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules.

[0105] Optionally, for network elements in the ORAN system, each network element can implement the protocol layer functions shown in Table 1 below.

[0106] Table 1

[0107] It should be noted that in the ORAN system, the access network equipment in this application can be one or more network elements listed in Table 1 above.

[0108] The architecture of the CU and DU of the access network equipment is described below. An access network equipment includes at least one CU and at least one DU. Optionally, the access network equipment may also include at least one RU.

[0109] The following description uses an access network device consisting of one CU and one DU as an example. The CU has some core network functions and can include CU-CP and CU-UP. The CU and DU can be configured according to the protocol layer functions of the wireless network they implement. For example, the CU may be configured to implement the functions of the Packet Data Convergence Protocol (PDCP) layer and above (e.g., RRC and / or SDAP layers). The DU may be configured to implement the functions of protocol layers below the PDCP layer (e.g., RLC, MAC, and / or physical (PHY) layers). Alternatively, the CU may be configured to implement the functions of protocol layers above the PDCP layer (e.g., RRC and / or SDAP layers), and the DU may be configured to implement the functions of protocol layers below the PDCP layer (e.g., RLC, MAC, and / or PHY layers).

[0110] When a CU includes CU-CP and CU-UP, CU-CP is used to implement the control plane functions of the CU, and CU-UP is used to implement the user plane functions of the CU. For example, when a CU is configured to implement the functions of the PDCP layer, RRC layer, and SDAP layer, CU-CP is used to implement the RRC layer functions and the control plane functions of the PDCP layer, and CU-UP is used to implement the SDAP layer functions and the user plane functions of the PDCP layer.

[0111] The CU-CP can interact with network elements in the core network used to implement control plane functions. These network elements can be access and mobility function (AMF) network elements, such as the AMF in a 5G system. The AMF is responsible for mobility management in the mobile network, such as terminal device location updates, terminal device registration with the network, and terminal device handover.

[0112] CU-UP can interact with network elements in the core network used to implement user plane functions. These network elements, such as the user plane function (UPF) in a 5G system, are responsible for forwarding and receiving data in terminal devices.

[0113] The above CU and DU configurations are merely examples; the functions of the CU and DU can be configured as needed. For instance, the CU or DU can be configured to have more protocol layer functions, or only some protocol layer processing functions. For example, some RLC layer functions and protocol layer functions above the RLC layer can be placed in the CU, while the remaining RLC layer functions and protocol layer functions below the RLC layer can be placed in the DU. Furthermore, the functions of the CU or DU can be divided according to service type or other system requirements. For example, based on latency, functions that require low latency can be placed in the DU, while functions that do not require low latency can be placed in the CU.

[0114] DU and RU can cooperate to implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of DU and RU can be configured in various ways depending on the design. For example, a DU can be configured to implement baseband functions, and an RU can be configured to implement mid-RF functions. Another example is that a DU can be configured to implement higher-level functions in the PHY layer, and an RU can be configured to implement lower-level functions in the PHY layer, or to implement both lower-level and RF functions. Higher-level functions in the physical layer can include a portion of the physical layer's functions that are closer to the MAC layer, while lower-level functions in the physical layer can include another portion of the physical layer's functions that are closer to the mid-RF side.

[0115] It should be noted that the access network equipment can be a device or apparatus with a chip, or a device or apparatus with integrated circuits, or a chip, chip system, module, or control unit in the aforementioned device or apparatus; this application does not impose any specific limitation. It should also be noted that in this application, the term "access network equipment" can refer to the access network equipment itself, or to the chip, functional module, or integrated circuit within the access network equipment that performs the method provided in this application; this application does not impose any specific limitation.

[0116] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, with each RAN node performing a portion of the base station's functions. For example, RAN nodes can be central units (CUs), distributed units (DUs), CU-CPs, CU-UPs, or radio units (RUs). CUs and DUs can be configured separately or included in the same network element, such as a baseband unit (BBU). RUs can be included in radio equipment or radio units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs).

[0117] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules.

[0118] A terminal can be a device or module that accesses the aforementioned communication system and has corresponding communication functions. A terminal can also be called a terminal device, user equipment (UE), mobile station, mobile terminal, etc. Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart homes, smart offices, smart wearables, intelligent transportation, smart cities, etc. Terminals can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, vehicles, drones, helicopters, airplanes, ships, robots, robotic arms, smart home devices, transportation vehicles with wireless communication capabilities, communication modules, etc. The embodiments of this application do not limit the device form of the terminal. Terminals typically contain communication modules, circuits, or chips that perform corresponding communication functions. Terminals can also be configured with program instructions for performing corresponding communication functions.

[0119] Furthermore, the embodiments of this application can also be applied to other future communication technologies. The network architecture and service scenarios described in this application are for the purpose of more clearly illustrating the technical solutions of this application, and do not constitute a limitation on the technical solutions provided in this application. As those skilled in the art will understand, with the evolution of network architecture and the emergence of new service scenarios, the technical solutions provided in this application are also applicable to similar technical problems.

[0120] Figure 3 illustrates an application scenario applicable to an embodiment of this application. The transmitting device encodes an information bit sequence to obtain a data packet. After the transmitting device sends the data packet to the receiving device, the receiving device decodes the data packet to obtain the information bit sequence carried in the data packet. The transmitting device can be a network device, a component or device applied to a network device (e.g., a processor, circuit, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of a network device (e.g., a central unit (CU), a distributed unit (DU), or a radio unit (RU)). The transmitting device can also be a terminal device, a component or device applied to a terminal device (e.g., a processor, circuit, chip, or chip system), or a circuit or chip in the terminal device responsible for communication functions (e.g., a modem chip, also known as a baseband chip, or a system-on-a-chip (SoC) chip containing a modem core, or a system-in-package (SIP) chip). The receiving end device can be a network device, a component or device applied to a network device (such as a processor, circuit, chip, or chip system), or a logic module or software (such as a CU, DU, or RU) that can implement all or part of the functions of the network device. The receiving end device can also be a terminal device, a component or device applied to a terminal device (such as a processor, circuit, chip, or chip system), or a logic module or software that can implement all or part of the functions of the terminal device.

[0121] It should be noted that the sending and receiving devices can be of the same type, such as both being network devices, or both being terminal devices. Alternatively, the sending and receiving devices can be of different types, such as the sending device being a network device and the receiving device being a terminal device; or, for example, the sending device being a terminal device and the receiving device being a network device. No specific limitation is made here.

[0122] In physical layer data transmission, information is sent at the transport block (TB) granularity. If a TB is corrupted, it needs to be retransmitted. If the number of retransmitted TBs exceeds the packet delay budget (PDB), the retransmission is meaningless and will affect the transmission of data packets. However, existing overlay coding transmission schemes typically only consider the overlay between CBs and do not consider the overlay transmission between TBs.

[0123] Based on this, this application provides a method. Referring to Figure 4, a communication method in this application includes:

[0124] 401. The transmitting device determines the first data;

[0125] The first data includes a first code block, which is obtained by superimposing multiple code blocks, and at least two of the multiple code blocks belong to different first transmission blocks.

[0126] In this embodiment of the application, the first data includes a plurality of second transmission blocks, each of which is composed of a plurality of superimposed code blocks. The plurality of superimposed code blocks include a first code block, which is obtained by superimposing multiple code blocks from different first transmission blocks. The first transmission block is also referred to as the original transmission block.

[0127] The transmitting device serially arranges N transport blocks (TBs), stacking them with S CBs at intervals of S, where S is the number of second transport blocks, also known as the number of processes. For example, when the first CB of TB1 is stacked with the first CB of TB2, the second CB of TB1 can also be stacked with the second CB of TB2. Assuming that the CBs obtained by stacking the first CB of TB1 and the first CB of TB2 are used to form one second transport block, then the CBs obtained by stacking the second CB of TB1 and the second CB of TB2 are used to form another second transport block. The number of CBs in each second transport block is called the chain length, denoted by L. The chain length L indicates the maximum number of CBs that can be stacked in a second transport block; in other words, the chain length L is the maximum number of CBs that a second transport block can contain. The chain length L can be pre-configured or based on the number of CBs in the first transport block with the smallest number of CBs; the specific choice is not limited here.

[0128] It should be noted that the overlay window size M can be configured or indicated by signaling. The overlay window size M is used to indicate that the first code block is obtained by overlaying a maximum of M code blocks.

[0129] As an example, as shown in Figure 5, there are four first transport blocks: TB1 contains 10 CBs, TB2 contains 12 CBs, TB3 contains 11 CBs, and TB4 contains 9 CBs. In one possible implementation, the number of second transport blocks is the same as the number of first transport blocks; that is, the number of TBs obtained after inter-TB encoding superposition is the same as the number of TBs before superposition. For example, the transmitting device performs inter-TB encoding superposition on four TBs to obtain four TBs, and the bit information carried in these four TBs is different from the bit information in the original transport blocks. In another possible implementation, the number of second transport blocks is different from the number of first transport blocks. For example, the transmitting device performs inter-TB encoding superposition on four TBs to obtain eight new TBs; the specific implementation is not limited here.

[0130] In this embodiment of the application, the code blocks constituting the second transport block can be superimposed in various ways. The following describes different superimposition methods using the example of the number of second transport blocks S equaling 4, the chain length L equaling 9, and the superimposition window M equaling 3:

[0131] 1. First, stack between TBs, then stack within TBs.

[0132] In one possible implementation, the transmitting device can first superimpose CBs at the same location in different TBs, and then superimpose CBs at different locations within the same TB.

[0133] As shown in Figure 6, the second transport block is TB1', and the first CB of TB1' is represented by CB_A. According to the BMST encoding scheme, the first CB of TB1 does not need to be superimposed, so CB_A is the first CB of TB1.

[0134] The second CB of TB1' is denoted by CB_B, which is obtained by superimposing the first CB of TB1 and the first CB of TB2.

[0135] The third CB of TB1' is denoted by CB_C, which is obtained by superimposing the first CB of TB1, the first CB of TB2, and the first CB of TB3.

[0136] The fourth CB of TB1' is represented by CB_D, which is obtained by superimposing the first CB of TB2, the first CB of TB3, and the first CB of TB4.

[0137] The fifth CB of TB1' is denoted by CB_E. In CB_E, since the first CB of all TBs from TB1 to TB4 has been superimposed, the first (1+4)th CB of TB1, i.e., the fifth CB, needs to be superimposed in CB_E. Therefore, CB_E is obtained by superimposing the first CB of TB3, the first CB of TB4, and the fifth CB of TB1.

[0138] Similarly, when the 9th CB of TB1 is superimposed, the second transport block TB1' contains 9 CBs, and superimposition stops.

[0139] The details are shown in Table 2 below:

[0140] Table 2: Stacking method of code blocks in TB1'

[0141] In this embodiment of the application, since the data in the first data is obtained by superimposing the data in multiple first transmission blocks, when the data transmission in the data packet is faulty, the receiving device can correct the faulty data according to the first data in the data packet, thereby enabling the data in the data packet to be successfully decoded and improving the performance gain of mutual error correction between TBs.

[0142] It should be noted that the above overlay method is only an example. In practical applications, the transmitting device can also overlay CBs at different positions in different TBs. As shown in Figure 7, the second transport block is TB1', the first CB of TB1' is represented by CB_A, and CB_A is the second CB of TB1.

[0143] The second CB of TB1' is denoted by CB_B, which is obtained by superimposing the second CB of TB1 and the fifth CB of TB2.

[0144] The third CB of TB1' is denoted by CB_C, which is obtained by superimposing the second CB of TB1, the fifth CB of TB2, and the first CB of TB3.

[0145] The fourth CB of TB1' is represented by CB_D, which is obtained by superimposing the fifth CB of TB2, the first CB of TB3, and the third CB of TB4.

[0146] The fifth CB of TB1' is represented by CB_E, which is obtained by superimposing the first CB of TB3, the third CB of TB4, and the fourth CB of TB1.

[0147] The details are shown in Table 3 below:

[0148] Table 3: Stacking method of code blocks in TB1'

[0149] In other words, the transmitting device can first superimpose CBs from different TBs, and then superimpose CBs from different positions within the same TB. The specifics are not limited here.

[0150] Optionally, the transmitting device can use a reverse overlay method. For example, after the CBs in TB4 are overlaid, a CB at a different position in TB4 is selected for overlay, and then the CBs in TB3, TB2, and TB1 are overlaid in reverse, and so on.

[0151] For example, as shown in Figure 8, the second transport block is TB1', and the fifth CB of TB1' is represented by CB_E. In CB_E, since the first CB of all TBs from TB1 to TB4 has been superimposed, the first (1+4)th CB of TB4, i.e., the fifth CB, needs to be superimposed in CB_E. Therefore, CB_E is obtained by superimposing the first CB of TB3, the first CB of TB4, and the fifth CB of TB4.

[0152] The 6th CB of TB1' is represented by CB_F, which is obtained by superimposing the 1st CB of TB4, the 5th CB of TB4, and the 5th CB of TB3.

[0153] The 7th CB of TB1' is represented by CB_G, which is obtained by superimposing the 5th CB of TB4, the 5th CB of TB3, and the 5th CB of TB2.

[0154] The 8th CB of TB1' is represented by CB_H, which is obtained by superimposing the 5th CB of TB3, the 5th CB of TB2, and the 5th CB of TB1.

[0155] The 9th CB of TB1' is represented by CB_I. In CB_I, since the 5th CB of all TBs from TB1 to TB4 has been superimposed, the 5+4th CB of TB1, i.e., the 9th CB, needs to be superimposed in CB_E. Therefore, CB_I is obtained by superimposing the 5th CB of TB2, the 5th CB of TB1, and the 9th CB of TB1. This reverse superposition method is shown in Figure 9.

[0156] The details are shown in Table 4 below:

[0157] Table 4: Overlay method of code blocks in TB1'

[0158] It should be understood that the above stacking method is described using a chain length L equal to 9 as an example. If the chain length L is greater than 9, after the 9th CB of TB4 is stacked, since TB4 does not have a 10th CB, the next CB used for stacking is the 10th CB of TB3. Similarly, after the 10th CB of TB1 is stacked, since TB1 does not have an 11th CB, the next CB used for stacking is the 11th CB of TB2, and so on.

[0159] 2. Stack within TB first, then stack between TB.

[0160] In one possible implementation, the transmitting device can first superimpose CBs at different locations within the same TB, and then superimpose CBs between different TBs.

[0161] As shown in Figure 10, the second transport block is TB1', and the first CB of TB1' is represented by CB_A. According to the BMST encoding scheme, the first CB of TB1 does not need to be superimposed, so CB_A is the first CB of TB1.

[0162] The second CB of TB1' is represented by CB_B. CB_B is obtained by superimposing the first CB of TB1 and the 1+4th CB of TB1. That is, CB_B is obtained by superimposing the first CB of TB1 and the 5th CB of TB1.

[0163] The third CB of TB1' is represented by CB_C, which is obtained by superimposing the first CB, the fifth CB, and the ninth CB of TB1.

[0164] The fourth CB of TB1' is denoted by CB_D. In CB_D, since the ninth CB of TB1 is the last CB in TB1, all the CBs in TB1 have been superimposed. Therefore, CB_D is obtained by superimposing the fifth CB of TB1, the ninth CB of TB1, and the first CB of TB2.

[0165] The fifth CB of TB1' is represented by CB_E, which is obtained by superimposing the ninth CB of TB1, the first CB of TB2, and the fifth CB of TB2.

[0166] The details are shown in Table 5 below:

[0167] Table 5: Overlay method of code blocks in TB1'

[0168] In this embodiment of the application, since the data in the first data is obtained by superimposing the data in multiple first transmission blocks, when the data transmission in the data packet is faulty, the receiving device can correct the faulty data according to the first data in the data packet, thereby enabling the data in the data packet to be successfully decoded and improving the performance gain of mutual error correction between TBs.

[0169] It should be noted that, in the embodiments of this application, superimposing CBs refers to performing an XOR operation on multiple CBs. For example, if the bit sequence corresponding to CB1 is 111 and the bit sequence corresponding to CB2 is 010, then the bit sequence after superimposing the two CBs is 101, that is, the same is 0 and different is 1.

[0170] 402. The sending device sends a first data packet to the receiving device, and correspondingly, the receiving device receives the first data packet from the sending device.

[0171] The transmitting device superimposes code blocks from different first transport blocks to obtain multiple data. Among these multiple data, the first data is included.

[0172] In this embodiment, the multiple data are essentially multiple second transmission blocks. Since each second transmission block is obtained by superimposing the data in multiple first transmission blocks, when the data transmission in the data packet is incorrect, the receiving device can correct the erroneous data according to the first data in the data packet, thereby enabling the data in the data packet to be successfully decoded and improving the performance gain of mutual error correction between TBs.

[0173] 403. The receiving device obtains the first transmission block based on the first data packet.

[0174] The receiving device uses a sliding window-based decoding algorithm to restore multiple data packets in the first data packet into multiple first transmission blocks, thereby completing the data transmission.

[0175] The receiving device performs joint decoding on multiple received sequences within the decoding window. Taking a decoding window length of 2 as an example, the window contains y... (t) and y (t+1) The soft information sequence of two codewords. As shown in Figure 11, the node LDPC represents the LDPC codec. For the t-th codeword, the soft information sequence y is used... (t) And the superimposed transmission codeword soft information sequence y (t+1) soft extrinsic information z 1→0 As input, it is decoded; and the corresponding soft information z is used as input. 0→1 During the decoding process of the (t+1)th codeword, the soft information sequence y is used for the (t+1)th codeword. (t+1) And the superimposed transmission codeword soft information sequence y (t) The soft extrinsic information is used as input for decoding. The receiving device performs hard decision on the corresponding codeword to obtain the corresponding real codeword c(t), and then obtains the information bit sequence u(t).

[0176] Optionally, the embodiment shown in Figure 4 further includes step 400. Step 400 may be performed before step 401.

[0177] 400. The sending device obtains configuration parameters.

[0178] Configuration parameters are used by the sending device to determine the first data, including the overlay window size M and / or the chain length L.

[0179] In one possible implementation, the overlay window size M and chain length L can be predefined by the protocol.

[0180] Optionally, the overlay window size M and chain length L can be indicated by a pattern index, where the pattern index is correlated with the overlay window size M and chain length L. For example, see Table 6 below:

[0181] Table 6: Relationship between pattern index, overlay window size M, and chain length L

[0182] As shown in Table 6, several fixed modes can be defined. For example, when the mode index is 1, the overlay window size M is 4 and the chain length L is 100; when the mode index is 2, the overlay window size M is 2 and the chain length L is 200. The specific mode is not limited here.

[0183] In another possible implementation, the overlay window size M and chain length L can be indicated by instruction information.

[0184] When the sending device is a terminal device, optionally, the sending device can receive downlink control information (DCI) from the network device, where the DCI carries bit indication information. For example, the DCI carries 3 bits of indication information to indicate the overlay window size M. When the indication information is 001, it indicates that the overlay window size M is 2; when the indication information is 100, it indicates that the overlay window size M is 3, and the specific value is not limited here.

[0185] Optionally, the sending device can receive RRC signaling from the network device. A new field, configured as {2,3,4,…}, is added to this RRC signaling to indicate the overlay window size M, with a default overlay window size M of 2.

[0186] Optionally, the transmitting device may receive DCI or RRC signaling from the network device, wherein the DCI or RRC signaling is used to indicate the pattern index. The transmitting device determines the overlay window size M and / or chain length L based on the pattern index.

[0187] Optionally, the embodiment shown in FIG4 further includes step 402a. Step 402a may be performed after step 402.

[0188] 402a. The transmitting device sends configuration parameters to the receiving device, and the receiving device receives the configuration parameters from the transmitting device accordingly.

[0189] In one possible implementation, the overlay window size M and chain length L are dynamically changing; therefore, the transmitting device needs to send the overlay window size M and / or chain length L to the receiving device. The following describes the transmission method of the transmitting device according to the device type of both the transmitting and receiving devices:

[0190] 1) The sending device is a network device, and the receiving device is a terminal device.

[0191] When the sending device is a network device and the receiving device is a terminal device, the sending device can send DCI or RRC signaling to the receiving device to indicate the overlay window size M.

[0192] Optionally, the transmitting device can send a DCI or MAC-CE to the receiving device to indicate the mode index, enabling the receiving device to determine the overlay window size M and chain length L based on the mode index and predefined associations (as shown in Table 6).

[0193] 2) The sending device is a terminal device, and the receiving device is a network device.

[0194] When the sending device is a terminal device and the receiving device is a network device, the sending device can send uplink control information (UCI) to the receiving device to indicate the overlay window size M.

[0195] Optionally, the transmitting device can send a UCI to the receiving device to indicate the mode index, enabling the receiving device to determine the overlay window size M and chain length L based on the mode index and predefined associations (as shown in Table 6).

[0196] 3) The sending device is a terminal device, and the receiving device is a terminal device.

[0197] When both the sending and receiving devices are terminal devices, the sending device can send sidelink control information (SCI) to the receiving device to indicate the overlay window size M.

[0198] Optionally, the sending device can send an SCI to the receiving device to indicate the pattern index, enabling the receiving device to determine the overlay window size M and chain length L based on the pattern index and predefined associations (as shown in Table 6).

[0199] The communication method in the embodiments of this application has been described above. The communication device in the embodiments of this application is described below. Referring to Figure 12, the communication device 1200 can be used to execute the process performed by the sending device in the embodiment shown in Figure 4. For details, please refer to the relevant descriptions in the foregoing method embodiments. The communication device 1200 can be a network device, or a component or device applied to a network device (e.g., a processor, circuit, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of a network device. The communication device can also be a terminal device, or a component or device applied to a terminal device (e.g., a processor, circuit, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of a terminal device.

[0200] The communication device 1200 includes an interface module 1201 and a processing module 1202.

[0201] The processing module 1202 is used for data processing. The interface module 1201 can implement corresponding communication functions. The interface module 1201 can also be called a communication interface or a communication module.

[0202] Optionally, the communication device 1200 may further include a storage module, which can be used to store program code, program instructions and / or data. The processing module 1202 can read the instructions and / or data in the storage module so that the communication device 1200 can implement the aforementioned method embodiments.

[0203] The communication device 1200 can be used to perform the actions performed by the transmitting device in the above method embodiments. For example, it can be the transmitting device itself, a communication module within the transmitting device, or a circuit or chip within the transmitting device responsible for communication functions. The communication device 1200 can be the transmitting device or a component configurable on the transmitting device. The processing module 1202 is used to perform processing-related operations on the transmitting device side in the above method embodiments. The interface module 1201 is used to perform reception-related operations on the transmitting device side in the above method embodiments.

[0204] Optionally, the interface module 1201 may include a sending module and a receiving module. The sending module is used to perform the sending operation in the above method embodiments. The receiving module is used to perform the receiving operation in the above method embodiments.

[0205] It should be noted that the communication device 1200 may include a transmitting module but not a receiving module. Alternatively, the communication device 1200 may include a receiving module but not a transmitting module. Specifically, it depends on whether the above-described scheme performed by the communication device 1200 includes both transmitting and receiving actions. For example, the communication device 1200 is used to perform the actions performed by the transmitting device in the embodiment shown in Figure 4. For details, please refer to the relevant descriptions in the embodiment shown in Figure 4; these will not be elaborated upon here.

[0206] For example, the communication device 1200 is used to execute the following scheme:

[0207] Processing module 1202 is used to determine first data, the first data including a first code block, the first code block being obtained by superimposing multiple code blocks, and at least two of the multiple code blocks belonging to different first transmission blocks;

[0208] Interface module 1201 is used to send a first data packet, which includes multiple data items, including the first data item.

[0209] In one possible implementation, interface module 1201 is also used to obtain configuration parameters, which are used to determine the first data.
