[0044] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0045] It should be noted that all actions of acquiring signals, information or data in the present disclosure are performed with the authorization given by the owner of the corresponding device.

[0046] At present, the 3GPP's fifth-generation mobile communication technology (5th-Generation, 5G) protocol stack solution is being promoted. It is proposed that the protocol stack function of the data link layer needs to process data packets with high efficiency and low latency, and requires the long-term evolution technology (Long Term Evolution, LTE) as the baseline. Among them, the data link layer includes three protocol layers: the packet data convergence protocol (Packet Data Convergence Protocol, PDCP) layer, the radio link control (Radio Link Control, RLC) layer, and the media access control (Medium Access Control, MAC) layer. Among them, each protocol layer has an independent data protocol unit PDU, and the way of forming PDU in each protocol layer is different, which increases the overall overhead of the data link layer. For example, PDCP does not have a cascading function. PDCP will allocate a PDCP sequence number (Serial, SN) for the data packet sent by the application layer, and after encryption and header compression to increase the PDCP header overhead, form a PDCP protocol data unit (PDU) and then forward it to RLC. RLC sends multiple PDCP PDUs in one RLC PDU to complete the packet cascading function. However, in the latest development of the fifth generation mobile communication technology, the RLC cascading capability has been reduced, that is, each RLC PDU can be cascaded to a maximum of 2 PDCP PDCs. Since a MAC PDU header overhead is required for each RLC PDU, more overhead will be generated, reducing the data transmission speed and the flexibility of business processing. If the traditional mapping processing solution between PDU and TB is used again, a TB can only encapsulate multiple MAC PDUs of the same receiving node. On the one hand, it cannot expand multi-node reception, and on the other hand, too much overhead will reduce the processing efficiency between PDU and TB.

[0047] In order to solve the above problems, the present disclosure provides a TB packaging method, a TB analysis method, a device, a medium and a chip. The following first introduces some applicable embodiments of the present disclosure.

[0048] See also Figure 1 FIG. 1 is a schematic diagram showing a flattening process of a protocol stack according to an exemplary embodiment. Figure 1As shown, the protocol stack involved in the wireless ad hoc network is similar to the top-down layered protocol stack architecture of 4G (LTE) / 5G users, and is flattened, which retains the transport layer, data link layer and physical layer. Among them, the transport layer is mainly responsible for constructing the raw data into a data service unit (SDU) that can be recognized by all nodes. The data link layer is mainly responsible for splicing the SDU into a protocol data unit (PDU) that can be recognized by neighboring nodes, where one PDU can include at least one SDU or part of the SDU, and this disclosure does not make too many restrictions and details. The physical layer (Physical Layer, PHY) is mainly responsible for providing a specific size of transport block (TB) to carry one or more complete PDUs of different receiving nodes, where one TB includes at least one PDU, and this disclosure does not make too many restrictions and details. Under the premise of ensuring transmission reliability, it is necessary to more simply and effectively implement SDU parsing, PDU multiplexing and demultiplexing (ie, PDU encapsulation and parsing), and mutual mapping between PDU and TB (ie, PDU to TB mapping, TB to PDU parsing). Based on this architecture, the user plane layered protocol architecture can be flattened while ensuring the stability of data service transmission and improving the effectiveness of data transmission.

[0049] See also Figure 2A FIG. 1 is a schematic diagram showing a transmission format of a TB according to an exemplary embodiment. Figure 2A The TB shown may include a header field 101 and a payload field 102. The header field 101 may refer to a header field with clear field content and fixed length.

[0050] The above-mentioned header field 101 may include a sending node indication area 1011, and the sending node indication area 1011 is used to indicate or carry the identifier of the sending node. That is, it indicates which sending node sends the TB. The above-mentioned load field 102 can be used to carry the corresponding PDU. Usually, one TB can carry one or several PDUs. The figure shows the example of carrying n PDUs, and n is a positive integer customized by the system or user according to actual conditions. Optionally, the above-mentioned load field 102 may also include a filling area, and the filling area is used to carry corresponding filling data. The filling data may be data content customized by the system, such as filling with data such as 0xFF or 0, etc., and the present disclosure does not make too many restrictions and details on this. The present disclosure does not limit the transmission format of the above-mentioned PDU. For example, the transmission format of the traditional PDU may be adopted, and the following may be adopted. Figure 2B The transmission format of the PDU shown, etc.

[0051] It can be seen that the above TB transmission format has the following advantages: the transmission block TB no longer serves one receiving node but can carry data of several receiving nodes that meet the transmission conditions and does not require too much redundant header overhead, which is beneficial to improving the performance of data transmission.

[0052] See also Figure 2B FIG. 1 is a schematic diagram showing a transmission format of a PDU according to an exemplary embodiment. Figure 2B The PDU shown may include a header field 201 and a payload field 202. The above-mentioned header field 201 may refer to a header field with clear field content and fixed length. The above-mentioned header field 201 may include a receiving node indication area 2011, a sending sequence number indication area 2012 and a length indication area 2013. The above-mentioned receiving node indication area 2011 is used to indicate the receiving node corresponding to the PDU, that is, to indicate which receiving node can demultiplex the PDU. The above-mentioned sending sequence number indication area 2012 is used to indicate the sending sequence number corresponding to the PDU, that is, to indicate which PDU it is, so that it can quickly assist in the adjustment of the PDU demultiplexing state and improve the synchronization detection efficiency of the SDU under abnormal reception. Each receiving node maintains a separate sending sequence number (PDU_SN). The sending sequence number PDU_SN can be updated to (PDU_SN+1)%PDU_SN_MAX after each use, where PDU_SN_MAX refers to a preset PDU sequence number, such as the maximum sending sequence number of the PDU, which usually depends on the number of valid bits in the sending sequence number indication area. The above-mentioned length indication area 2013 is used to indicate the length of the load in the PDU, that is, the length of all or each SDU.

[0053] The payload field 202 may be used to carry the corresponding SDU. Usually, a PDU may include one or more SDUs, which is not limited or detailed in this disclosure. The transmission format of the SDU is not limited in this disclosure. For example, the following Figure 2C The transmission format of the SDU shown, etc.

[0054] It can be seen that the transmission format of the above PDU has the following advantages: 1) The header field of PDU no longer indicates the number of spliced ​​SDUs and their corresponding lengths, so the PDU does not need to calculate the header overhead before deciding the number of SDUs that can be multiplexed during the multiplexing process. It only needs to connect the SDUs one by one in the payload field, thereby simplifying the construction complexity; 2) The payload field of PDU can splice multiple SDUs, which greatly improves the multiplexing performance compared to the 5G RLC PDU, which can only splice 2 SDUs at most; 3) The payload field of PDU no longer has padding content, which is different from the 4G RLC PDU, which has padding content, and also improves the multiplexing performance; 4) Since there is a probability of false detection in the synchronization header, adding an integrity protection area to the header (which depends on part of the data content) effectively reduces the probability of false detection while also reducing the probability of attack on the constructed SDU.

[0055] See also Figure 2C FIG. 1 is a schematic diagram showing a transmission format of an SDU according to an exemplary embodiment. Figure 2C The SDU shown may include a header field 301 and a payload field 302, and may optionally include an extension field 303. The header field 301 may refer to a header field with clear field content and fixed length. The transport layer may receive a corresponding data packet (e.g., an Ethernet data packet) according to the offset address of the header length of the SDU to reduce the number of data copies, improve data transmission performance, and facilitate the subsequent multiplexing and demultiplexing process between the PDU and the SDU to become simpler and faster.

[0056] The above-mentioned header field 301 may include a synchronization indication area 3011, an extension indication area 3012, a length indication area 3013 and an integrity protection area 3014. The above-mentioned synchronization indication area 3011 is used to indicate the synchronization code position of the SDU. That is, based on the synchronization indication area 3011, the synchronization code position can be found from the encapsulated corresponding PDU to determine the position of the SDU. The present disclosure does not limit the size and representation of the above-mentioned synchronization indication area 3011, for example, 1 byte content is usually represented by 0x55, etc. The above-mentioned extension indication area 3012 is used to indicate whether the SDU includes the above-mentioned extension field 303, and usually the extension field 303 is located in the tail area of ​​the SDU. The present disclosure does not limit the size of the above-mentioned extension indication area 3012, for example, it can usually occupy 8 bits, and a bit mapping method can be used to determine whether to include 8 different transmission status indications. For example, the first bit indicates the transmission sequence number of the SDU, and the second bit indicates the priority of the SDU in the wireless ad hoc network. The present disclosure does not limit the representation of the above-mentioned extended indication area. For example, when the value of the above-mentioned extended indication area is 0x00, it is used to indicate that there is no extended content; when the value of the above-mentioned extended indication area is 0x01, it is used to indicate the transmission sequence number of the SDU; when the value of the above-mentioned extended indication area is 0x02, it is used to indicate the priority of the SDU; when the value of the above-mentioned extended indication area is 0x03, it is used to indicate that the transmission sequence number and priority of the SDU can be included at the same time. The above-mentioned length indication area 3013 is used to indicate the length of the entire SDU, and its purpose can be to quickly synchronize the next SDU. The present disclosure does not limit the size and representation of the above-mentioned length indication area 3013. For example, it can occupy 12 bits and can indicate 2048 bytes, which is larger than the traditional Ethernet data packet length (the Ethernet data packet length is usually less than 1600 bytes). The above-mentioned integrity protection area 3014 is used to make integrity and legal judgments on the SDU. The present disclosure does not limit the size and representation of the above-mentioned integrity protection area 3014. For example, it can occupy 1 byte. The present disclosure does not limit the specific implementation of the above-mentioned integrity legal judgment. For example, the present disclosure can use a preset algorithm (such as the checksum algorithm of the Internet Protocol (IP)) to calculate the result of 2 bytes by taking the above-mentioned synchronization indication area 3011, the above-mentioned extension indication area 3012, the above-mentioned length indication area 3013 and the partial data packet as the load (such as the first dozens of bytes in the Ethernet data packet) as input, extract the data content of the last 1 byte and match it with the check data carried in the above-mentioned integrity protection area 3014. If the match is successful, the result of the above-mentioned integrity legal judgment is legal; otherwise, the result of the above-mentioned integrity legal judgment is illegal.

[0057] The payload field 302 is used to carry a complete data packet, such as an Ethernet data packet.

[0058] The above-mentioned extension field 303 refers to an expandable field that can be located at the end of the SDU, which is mainly used to indicate the sending status of the transmission service in the protocol. For example, it may include but is not limited to any one or more of the following combinations: the sending sequence number, priority, delay parameter or other custom information of the SDU. The above-mentioned sending sequence number refers to the sending sequence number of the SDU, such as the sending number, etc. The above-mentioned priority refers to the priority of the SDU, which is convenient for the subsequent processing of the SDU according to the priority, such as forwarding the SDU according to the corresponding priority, etc. The above-mentioned delay parameter may refer to the minimum delay guarantee parameter required by the SDU, which is used to reflect the transmission delay of the SDU, such as the minimum transmission delay, etc. The length of each field or area involved in the above-mentioned SDU can be an integer number of bytes, and the length of the entire SDU can also be an integer number of bytes. The content settings of the above-mentioned fields can be customized in advance by the system or the user according to the actual situation, and this disclosure does not make too many restrictions and details on this.

[0059] It can be seen that the transmission format of the SDU disclosed above can have the following advantages: the header field of the SDU is not for service indication, but can be used for subsequent PDU multiplexing and demultiplexing. The SDU indicates the service attributes through the extension field at the end, which increases the flexibility of service transmission. Adding an integrity protection field to the SDU header field can improve the accuracy of synchronization. The integrity protection field includes part of the content of the Ethernet data packet, which can improve the effectiveness and reliability of the synchronization header. Because partial data can be received to quickly confirm whether the synchronization is valid, the effectiveness of the synchronization header is improved; once the data is incorrect or tampered with, it can be confirmed that the synchronization is invalid.

[0060] The sending node involved in the present disclosure may also be referred to as a sending end or a sending device, which is an entity for receiving or transmitting signals, such as a terminal device or a network device.

When the above-mentioned receiving node is a network device, the network device may be composed of a centralized unit (CU) and a distributed unit (DU), wherein the CU may also be referred to as a control unit (Control Unit). The CU-DU structure may be used to split the protocol layer of a network device, such as a base station, and the functions of some protocol layers are placed in the CU for centralized control, and the functions of the remaining part or all of the protocol layers are distributed in the DU, and the DU is centrally controlled by the CU. The embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the receiving node.

The encapsulation length (TB_MB) of the above-mentioned target TB refers to the length of the current encapsulation of the above-mentioned target TB, and can also be understood as the encapsulation length of the above-mentioned target TB at the current moment. During initialization, the encapsulation length (TB_MB) of the above-mentioned target TB can be directly set to the fixed header length of the above-mentioned target TB. The above-mentioned transmission capability may refer to the transmission format of the receiving node, for example, it may include but is not limited to differential phase shift keying (DPSK), quadrature digital phase modulation (QPSK) or other transmission formats or methods, etc. The preset transmission capacity (TB_C) of the above-mentioned target TB can be directly set to the transmission capacity C1 of the first receiving node.

[0065] In an optional embodiment, the present disclosure may assign the identifier of the sending node to the sending node indication area of ​​the target TB. Figure 2A The relevant introduction in the embodiments will not be repeated here.

[0066] S302. Perform encapsulation processing based on the TB information to obtain the target TB; wherein the target TB includes a header field and a load field, the header field is used to carry the identifier of the sending node, and the load field is used to carry the corresponding PDU.

[0067] By implementing the embodiments of the present disclosure, the sending node can obtain the TB information to be encapsulated, the TB information includes at least one receiving node and the transmission capability of the receiving node, the transmission capability is used to indicate the size of the corresponding encapsulated target TB and its preset transmission capability; encapsulation processing is performed based on the TB information to obtain the target TB; wherein the target TB includes a header field and a load field, the header field is used to carry the identifier of the sending node, and the load field is used to carry the corresponding PDU. In this way, the corresponding target TB can be encapsulated directly according to the field format based on the TB information, which is conducive to improving the processing efficiency of TB encapsulation. Thereby solving the technical problems existing in the above-mentioned related technologies such as reducing the processing efficiency between PDU and TB.

[0068] In step S302, the present disclosure may sequentially traverse each receiving node in the above-mentioned at least one receiving node (also referred to as a receiving node set) to perform corresponding TB encapsulation processing. The present disclosure does not limit the specific implementation of the above-mentioned encapsulation processing. For example, the relevant content is described by taking the target node as an example, but it does not constitute a limitation. The target node is any one of the above-mentioned at least one receiving node. Please refer to Figure 5 FIG. 1 is a schematic diagram of a packaging process according to an exemplary embodiment. Figure 5 The process shown may include the following implementation steps: S501. When the transmission capacity of the target node is greater than or equal to the preset transmission capacity of the target TB, PDU encapsulation is performed on the target node to obtain a target PDU corresponding to the target node.

[0069] After obtaining the above-mentioned TB information, the present disclosure can traverse each receiving node in the receiving node set. The present disclosure takes the target node as an example to specifically introduce the TB encapsulation processing. The present disclosure can determine whether the transmission capacity of the above-mentioned target node is greater than or equal to the preset transmission capacity of the target TB. If it is determined that the transmission capacity of the above-mentioned target node is less than the preset transmission capacity of the target TB, step S504 can be executed; on the contrary, if it is determined that the transmission capacity of the above-mentioned target node is greater than or equal to the preset transmission capacity of the target TB, it indicates that the above-mentioned target TB can carry the PDU of other receiving nodes. The present disclosure can first perform PDU encapsulation on the above-mentioned target node, so as to encapsulate and obtain the target PDU corresponding to the above-mentioned target node. The present disclosure does not go into too much detail about the specific implementation method of PDU encapsulation, and it can correspond to the relevant embodiments involved in the PDU encapsulation method of the relevant case. The preset transmission capacity (TB_C) of the above-mentioned target TB refers to the transmission capacity value pre-defined by the system or the user, for example, it can usually be the transmission capacity C1 of the first receiving node, or it can be the default capacity value set by the system, etc., and the present disclosure does not make too many restrictions and details on this.

[0070] In some optional embodiments, after performing PDU decompression / encapsulation on the target node in the above-mentioned receiving node set, the present disclosure may assign and update the length of the corresponding target PDU, for example, PDU_TB=TB_B-TB_MB. The length of the above-mentioned target PDU (PDU_TB) refers to the total length of the target PDU, which may include the header field length (PDU_H) of the target PDU and the payload field length (PDU_PB) of the target PDU.

[0071] S502: Update the encapsulation length of the target TB based on the length of the target PDU.

[0072] The present disclosure may update or recalculate the encapsulation length (TB_MB) of the target TB according to the decompression / encapsulation result, and may specifically be updated according to the length of the target PDU, for example, it may be updated with reference to the following formula (1): Formula (1) Among them, TB_MB represents the encapsulation length of the above target TB, PDU_PB represents the payload field length of the above target PDU, and PDU_H represents the header field length of the above target PDU. The header field length (PDU_H) of the above target PDU and the payload field length (PDU_PB) of the target PDU together constitute the length of the above target PDU (PDU_TB).

[0073] S503. When the encapsulation length of the target TB is equal to the size of the target TB, encapsulate the target PDU into the target TB to complete the encapsulation of the target TB; wherein the target node is any receiving node in the TB information.

[0074] After updating the encapsulation length (TB_MB) of the target TB, the present disclosure can determine whether the encapsulation length (TB_MB) of the target TB is equal to the size (TB_B) of the target TB. If the encapsulation length (TB_MB) of the target TB is equal to the size (TB_B) of the target TB, it can be determined that the encapsulation of the entire target TB has been completed, and the process can be ended or exited. The target PDU is encapsulated in the target TB. On the contrary, if the encapsulation length (TB_MB) of the target TB is less than the size (TB_B) of the target TB, step S504 can be entered.

[0075] S504: Delete the target node in the TB information.

[0076] The present disclosure determines that the encapsulation length (TB_MB) of the target TB is smaller than the size (TB_B) of the target TB and / or the transmission capacity (C i ) is less than the preset transmission capacity (TB_C) of the target TB, the target node may be deleted from the at least one receiving node (ie, the receiving node set).

[0077] S505: Update the next receiving node to the target node, and repeat the above steps S501-S505.

[0078] The present disclosure may update the next receiving node in the at least one receiving node (i.e., the receiving node set) as the target node, and repeat the above Figure 5 The process shown in the figure ends until each receiving node in the at least one receiving node (ie, the receiving node set) is traversed.

[0079] Some optional embodiments of the present disclosure are described below.

[0080] See also Figure 6 FIG. 1 is a flow chart of another packaging process according to an exemplary embodiment. Figure 6 The flowchart shown may include the following implementation steps: S601: Determine whether the encapsulation length of the target TB supports transmission with other transmission capabilities, and the other transmission capabilities are smaller than the preset transmission capacity of the target TB.

[0081] After traversing each receiving node in the at least one receiving node, that is, when the receiving node set is empty, the present disclosure can judge / determine whether the encapsulation length (TB_MB) of the above target TB supports other lower transmission capacity transmission or carrying. If it is determined that the encapsulation length (TB_MB) of the above target TB supports other lower transmission capacity transmission, step S602 can be continued; conversely, if it is determined that the encapsulation length (TB_MB) of the above target TB does not support other lower transmission capacity transmission, step S603 can be continued. Among them, the above other transmission capacity must be less than the above preset transmission capacity.

[0082] S602: When supporting transmission with the other transmission capabilities, re-determine the size of the target TB corresponding to the other transmission capabilities, and perform encapsulation processing based on the encapsulation length of the target TB and the size of the target TB.

[0083] When the present disclosure determines that the encapsulation length (TB_MB) of the target TB supports other lower transmission capacity transmission, the transmission capacity can be reduced, the other transmission capacity can be determined, and the size of the target TB corresponding to the other transmission capacity can be recalculated. The calculation of the size of the target TB can be referred to above. Figure 3 The relevant introduction in the embodiment is not repeated here. Then, encapsulation processing is performed based on the encapsulation length (TB_MB) of the target TB and the size (TB_B) of the target TB, which may be described in detail below in this disclosure.

[0084] S603: When the other transmission capability transmission is not supported, encapsulation processing is performed based on the encapsulation length of the target TB and the size of the target TB.

[0085] When it is determined that the encapsulation length (TB_MB) of the target TB does not support transmission with other lower transmission capabilities, the present disclosure may perform encapsulation processing based on the encapsulation length (TB_MB) of the target TB and the size (TB_B) of the target TB. The present disclosure does not limit the specific implementation of the encapsulation processing, which is described in detail below.

[0086] In one implementation, when the encapsulation length (TB_MB) of the target TB is greater than or equal to the size (TB_B) of the target TB, it can be determined that the encapsulation of the entire target TB has been completed, and the process can be ended or exited.

[0087] In another embodiment, when the encapsulation length (TB_MB) of the target TB is smaller than the size (TB_B) of the target TB, the present disclosure may perform padding processing on the target TB, for example, padding with preset characters, such as 0xFF or 0, etc., which is not limited or detailed in the present disclosure. The padding data / padding content corresponding to the padding processing may be carried in the padding area of ​​the target TB, and the corresponding data may refer to the aforementioned Figure 2A The relevant introduction about the filling area in the above-mentioned embodiment will not be repeated here.

[0088] It can be seen that since the PDU includes a length indication area, all PDUs can be read by making corresponding offsets according to the length indicated in each area, and the receiving node will only parse the PDU sent to itself or other PDUs with broadcast attributes. It can be seen that the above TB encapsulation has the following advantages: 1) The TB can include PDUs of multiple receiving nodes that meet the transmission conditions; 2) The size of the TB transmission block can reversely determine the transmission capacity, thereby improving the reliability of data transmission.

[0089] By implementing the embodiments of the present disclosure, the present disclosure can obtain TB information to be encapsulated, wherein the TB information includes at least one receiving node and the transmission capability of the receiving node, and the transmission capability is used to indicate the size of the corresponding encapsulated target TB and the preset transmission capability; encapsulation processing is performed based on the TB information to obtain the target TB; wherein the target TB includes a header field and a load field, wherein the header field is used to carry the identifier of the sending node, and the load field is used to carry the corresponding PDU. In this way, the corresponding target TB can be encapsulated directly according to the field format based on the TB information, which is conducive to improving the processing efficiency of TB encapsulation. Thus, the technical problems existing in the above-mentioned related technologies, such as reducing the processing efficiency between PDU and TB, are solved.

[0090] To help better understand the embodiments of the present disclosure, the following examples are given. Figure 7 FIG. 1 is a flow chart of a TB packaging process according to an exemplary embodiment. Figure 7 The process shown can be applied to a sending node, and may specifically include the following implementation steps: S701. A sending node obtains physical layer PHY resources and prepares a target transmission block TB.

[0091] S702: Calculate the set of receiving nodes currently supporting transmission and the transmission capability of each receiving node according to a specific algorithm (such as fairness, greed, priority, etc.). The receiving node set may include at least one receiving node, R i represents the i-th receiving node, C iIndicates the transmission capacity of the i-th receiving node. Set the preset transmission capacity of the target TB, for example, C=C1. Calculate the size of the target TB (TB_B) by the preset transmission capacity of the target TB. Assign a value to the header field of the TB: assign the identifier of the sending node to the sending node indication area. Set the encapsulation length of the target TB TB_MB = fixed header length.

[0092] S703: Determine whether the receiving node set is empty.

[0093] When the present disclosure determines that the receiving node set is not empty, step S704 may be continued to be executed; otherwise, when the present disclosure determines that the receiving node set is empty, step S708 may be continued to be executed.

[0094] S704: Determine whether the transmission capacity of the target node is greater than a preset transmission capacity. The preset transmission capacity is a system-defined setting, such as C.

[0095] When the present disclosure determines that the transmission capacity of the target node is greater than the preset transmission capacity, step S705 may be continued to be executed; otherwise, step S707 may be continued to be executed.

[0096] S705. For the first receiving node in the receiving node set as the above-mentioned target node, perform PDU multiplexing and assign a value to the length of the multiplexed target PDU (PDU_TB), for example, PDU_TB=TB_B- TB_MB. Among them, TB_B is the size of the target TB, and TB_MB is the encapsulation length of the target TB. According to the multiplexing result, the target PDU recalculates the encapsulation length of the target TB TB_MB=TB_MB+PDU_PB+ PDU_H, where PDU_PB is the payload length of the target PDU and PDU_H is the header field length of the target PDU.

[0097] S706 , determining whether the encapsulation length TB_MB of the target TB is equal to the size TB_B of the target TB.

[0098] When the present disclosure determines that the encapsulation length TB_MB of the target TB is not equal to or less than the size of the target TB, step S707 may be continued to be executed; otherwise, when the encapsulation length TB_MB of the target TB is determined to be equal to the size of the target TB, the process may be terminated and exited directly.

[0099] S707: Delete the first receiving node in the receiving node set and its corresponding transmission capability.

[0100] S708: Determine whether the encapsulation length TB_MB of the target TB can be transmitted / carried using other lower transmission capabilities.

[0101] When the present disclosure determines that the encapsulation length TB_MB of the target TB can be transmitted using other lower transmission capabilities, the step S709 may be continued to be executed; otherwise, when the present disclosure determines that the encapsulation length TB_MB of the target TB cannot be transmitted using other lower transmission capabilities, the step S710 may be continued to be executed.

[0102] S709: Reduce the preset transmission capacity C, determine other transmission capacity, and recalculate the size TB_B of the target TB based on the other transmission capacity.

[0103] S710 , determine whether the encapsulation length TB_MB of the target TB is smaller than the size TB_B of the target TB.

[0104] When the present disclosure determines that the encapsulation length TB_MB of the target TB is smaller than the size TB_B of the target TB, the step S711 may be continued to be executed; otherwise, when the encapsulation length TB_MB of the target TB is determined to be not smaller than the size TB_B of the target TB, the process may be ended and exited directly.

[0105] S711, exit directly after filling processing.

[0106] For details not described in the embodiments of the present disclosure, please refer to the aforementioned Figures 3 to 6 The specific introduction in the embodiments will not be repeated here.

[0107] See also Figure 8 FIG. 1 is a flow chart of a TB analysis method according to an exemplary embodiment. Figure 8 The method shown can be applied to a receiving node, and the method may include the following implementation steps: S801. Obtain a target TB to be parsed, where the target TB includes a header field and a payload field. The header field is used to carry an identifier of a sending node, and the payload field is used to carry a corresponding PDU.

[0108] In the present disclosure, the target TB may refer to the TB to be parsed received by the receiving node. The parsing of the target TB mainly involves the content of each field of the target TB, such as mainly parsing the PDU carried in the target TB. The present disclosure does not limit the implementation method for obtaining the target TB, such as receiving the target TB from the sending node. For the introduction of the transmission format of the target TB, please refer to the above Figure 2A The specific introduction in the embodiments will not be repeated here.

[0109] S802: Perform field analysis on the target TB.

[0110] The present disclosure does not limit the implementation method of the field parsing of the target TB. For example, see Fig. 9 FIG. 1 is a flow chart showing a field parsing process according to an exemplary embodiment. Fig. 9 The process shown may include the following implementation steps: S901 , parse the header field in the target TB to obtain the identifier (rID) of the sending node and the parsed length (TB_RB) of the target TB.

[0111] The present disclosure can first parse the content of the header field of the target TB to obtain the identification of the sending node carried in the sending node indication area of ​​the header field and the parsing length of the target TB. The parsing length (TB_RB) of the target TB can be used to indicate the length currently supported for parsing the target TB. During initialization, it can be set to the header field length of the target TB, that is, the field content parsing of the target TB can be started from the end position of the header field length of the target TB.

[0112] S902: Parse the payload field of the target TB based on the parsing length (TB_RB) of the target TB.

[0113] The present disclosure does not limit the specific implementation of the above step S901. For example, see Fig.10 FIG. 1 is a flow chart showing another field parsing process according to an exemplary embodiment. Fig.10 The process shown may include the following implementation steps: S1001 . Determine whether the parsed length of the target TB (TB_RB) is greater than or equal to the length of the target TB (TB_B).

[0114] The present disclosure may compare the parsed length (TB_RB) of the target TB and the length (TB_B) of the target TB. If the parsed length of the target TB is greater than or equal to the length of the target TB, step S1005 may be continued to determine that the parsing of the target TB is completed, and the process may be terminated at this time. On the contrary, when the parsed length of the target TB is less than the length of the target TB, it may be determined that the parsing of the target TB is not completed, and step S1002 may be continued.

[0115] S1002. When the parsed length (TB_RB) of the target TB is less than the length (TB_B) of the target TB, read the header field of the target PDU starting from the parsed length of the target TB, wherein the header field of the target PDU at least includes a receiving node corresponding to the target PDU.

[0116] When the present disclosure determines that the parsed length of the target TB is less than the length of the target TB, it can start reading the header field of the target PDU from the position of the parsed length TB_RB of the target TB, thereby obtaining the receiving node indication area, the sending sequence number indication area and the length indication area in the header field of the target PDU. The receiving node indication area carries / includes the receiving node corresponding to the target PDU. For the introduction of the contents of each field or area in the target PDU, please refer to the above Figure 2B The relevant introduction in the embodiments will not be repeated here.

[0117] S1003. When it is determined that the length of the target PDU is a valid length, determine whether the receiving node corresponding to the target PDU and the receiving node corresponding to the target TB are the same, and obtain a corresponding determination result.

[0118] The present disclosure can judge / determine whether the length of the above-mentioned target PDU is a valid length. The present disclosure does not limit its specific implementation method. For example, in one possible implementation method, the present disclosure can judge whether the above-mentioned target PDU meets the preset conditions. The preset conditions can be conditions pre-customized and set by the system or the user, which are used to judge whether the length of the above-mentioned target PDU is a valid length; for example, the above-mentioned preset conditions can at least include that the payload field of the above-mentioned target PDU does not carry preset padding data (such as 0xFF), and optionally can also include that the length of the above-mentioned target PDU is a preset length. For example, when the length of the above-mentioned target PDU is 2 bytes and the target PDU is not 0xFF, it can be determined that the above-mentioned target PDU meets the preset conditions, and accordingly the length of the above-mentioned target PDU is a valid length.

[0119] When the present disclosure determines that the length of the target PDU is not a valid length, it can be determined that the target PDU is a padding PDU, that is, the target PDU includes preset padding data, such as 0xFF, etc. On the contrary, when it is determined that the length of the target PDU is a valid length, it can continue to determine whether the receiving node corresponding to the target PDU is the same as the receiving node corresponding to the target TB, and specifically, it can be determined whether the identifiers of the two receiving nodes are the same, thereby obtaining a corresponding determination result. The determination result is specifically used to indicate whether the receiving node corresponding to the target PDU is the same as the receiving node corresponding to the target TB.

[0120] S1004. Based on the determination result, re-parse the load field of the target TB.

[0121] The present disclosure does not limit the specific implementation of the above step S1004. For example, in one implementation, when the above determination result is used to indicate that the receiving node corresponding to the above target PDU is the same as the receiving node corresponding to the above target TB, the present disclosure can obtain the above target PDU by reading from the target TB according to the length of the above target PDU. Optionally, the entire content of the above target PDU, the length of the above target PDU, the sending sequence number corresponding to the above target PDU and other information can also be used as input to the above target PDU parsing process, and then the target PDU is parsed. No excessive limitations or details are given here.

[0122] In another embodiment, when the above determination result is used to indicate that the receiving node corresponding to the above target PDU and the receiving node corresponding to the above target TB are not the same, the present disclosure can update the parsing length TB_RB of the above target TB based on the length of the above target PDU, for example, TB_RB=TB_RB+PDU_HB+ PDU_PB. Among them, PDU_HB represents the header field length of the above target PDU, and PDU_PB represents the load field length of the above target PDU, and the sum of the two is equal to the length of the entire above target PDU. After updating the parsing length TB_RB of the above target TB, the present disclosure can repeat the above steps S1001-S1005 until the entire target TB is parsed.

[0123] S1005: Determine that the above target TB analysis is completed, and then end the process.

[0124] To help better understand the embodiments of the present disclosure, please refer to Fig.11 FIG. 1 is a flow chart showing a TB analysis process according to an exemplary embodiment. Fig.11 The process shown may include the following implementation steps: S1101. A receiving node receives a target transport block TB from a physical layer PHY.

[0125] S1102, obtain the identification ID of the sending node from the header field of the target TB, set and read the parsing length TB_RB=TB_HB of the target TB, wherein TB_HB represents the header field length of the target TB, which is the fixed header field length of the target TB during initialization.

[0126] S1103 , determining whether the parsed length TB_RB of the target TB is greater than or equal to the length TB_B of the target TB.

[0127] When it is determined that the parsed length TB_RB of the target TB is greater than or equal to the length TB_B of the target TB, the process may be exited and ended. Conversely, when it is determined that the parsed length TB_RB of the target TB is less than the length TB_B of the target TB, step S1104 may be continued.

[0128] S1104. Read the header field of the target PDU starting from the parsed length TB_RB position of the target TB, thereby obtaining information such as a receiving node indication area, a sending sequence number indication area, and a length indication area in the header field of the target PDU.

[0129] S1105. Determine whether the length of the target PDU is a valid length.

[0130] When it is determined that the length of the above-mentioned target PDU is a valid length, step S1106 can be continued to be executed; conversely, when it is determined that the length of the above-mentioned target PDU is not a valid length, that is, invalid, step S1109 can be continued to be executed to determine that the above-mentioned target PDU is a padding PDU, and at this time, you can exit and end the process.

[0131] S1106: Determine whether the receiving node corresponding to the target PDU is the same as the receiving node corresponding to the target TB, that is, determine whether the receiving node ID is its own ID.

[0132] When it is determined that the receiving node corresponding to the target PDU is the same as the receiving node corresponding to the target TB, step S1107 can be continued; otherwise, when it is determined that the receiving node corresponding to the target PDU is not the same as the receiving node corresponding to the target TB, step S1108 can be continued.

[0133] S1107, read the entire target PDU according to the length of the target PDU. The entire content of the target PDU, the length of the target PDU, the sending sequence number and other information are used as inputs of the PDU parsing process to perform corresponding parsing processing, which is not limited or detailed in this disclosure.

[0134] S1108, update the parsed length of the target TB TB_RB = TB_RB + PDU_HB + PDU_PB. Wherein, PDU_HB represents the header field length of the target PDU, and PDU_PB represents the payload field length of the target PDU, and the sum of the two equals the length of the entire target PDU. Repeat the above steps S1103-S1109.

[0135] S1109: Determine that the target PDU is a filling PDU, and then exit and end the process.

[0136] For details not introduced or described in the embodiments of the present disclosure, please refer to the aforementioned Figures 8 to 10 The relevant introduction in the embodiments will not be repeated here.

[0137] By implementing the embodiments of the present disclosure, the embodiments of the present disclosure can have the following advantages: 1) The TB transmission block no longer serves a neighbor receiving node but can carry multiple one-hop neighbor node data that meet the transmission conditions and one receiving node data is a complete PDU, which greatly improves the transmission performance. 2) The TB transmission block size can also be used as a selection factor for adaptive modulation and coding AMC (Adaptive Modulation and Coding) to improve transmission reliability. 3) The data transmission protocol architecture is more flat, which greatly reduces the complexity of protocol implementation.
