Description

Technical Field

[0001] This invention relates to the field of mobile communication technology, specifically to a data transmission method, a terminal, and a base station. Background Technology

[0002] 5G and Artificial Intelligence (AI) are gradually integrating into people's lives and bringing new economic growth trends. With the rapid development of AI technology, future network architectures will increasingly integrate with AI. In the upcoming 6G era, AI will inevitably become an indispensable part of network architecture.

[0003] With the rapid development of AI technology, future network architectures will increasingly integrate with AI. Current AI models are trained on the network side, collecting data from the network or terminals to create AI models, which are then optimized based on the desired goals. In this approach, intelligent and network functions are relatively independent. This approach faces several challenges: 1) Increasing amounts of data need to be reported, consuming more network bandwidth. 2) Terminals are becoming increasingly intelligent, but current technology does not fully utilize their intelligence, failing to achieve end-to-end intelligence. 3) Data security is a sensitive factor in communication networks, and current technologies struggle to guarantee user data security.

[0004] It can be seen that the integration of existing network architecture with AI is still in the early stages of research.

[0110] Please see Figure 1 , Figure 1 This diagram illustrates a block diagram of a wireless communication system applicable to an embodiment of the present invention. The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 can also be referred to as a user terminal or user equipment (UE). The terminal 11 can be a mobile phone, tablet computer, laptop computer, personal digital assistant (PDA), mobile internet device (MID), wearable device, or in-vehicle device, etc. It should be noted that the specific type of terminal 11 is not limited in this embodiment of the present invention. Network device 12 can be a base station and / or a core network element. The base station can be a 5G or later version base station (e.g., gNB, 5G NR NB, etc.), or a base station in other communication systems (e.g., eNB, WLAN access point, or other access point, etc.). The base station can be referred to as a node B, evolved node B, access point, base transceiver station (BTS), radio base station, radio transceiver, basic service set (BSS), extended service set (ESS), B node, evolved B node (eNB), home B node, home evolved B node, WLAN access point, WiFi node, or any other suitable term in the field, as long as the same technical effect is achieved. The base station is not limited to specific technical terms. It should be noted that in the embodiments of the present invention, only the base station in the NR system is used as an example, but the specific type of base station is not limited.

[0111] The base station can communicate with terminal 11 under the control of a base station controller, which in various examples may be part of the core network or some base stations. Some base stations may communicate control information or user data with the core network via backhaul. In some examples, some of these base stations may communicate with each other directly or indirectly via backhaul links, which may be wired or wireless communication links. The wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on multiple carriers simultaneously. For example, each communication link may be a multi-carrier signal modulated according to various radio technologies. Each modulated signal may be transmitted on a different carrier and may carry control information (e.g., reference signals, control channels, etc.), overhead information, data, etc.

[0112] The base station can wirelessly communicate with terminal 11 via one or more access point antennas. Each base station can provide communication coverage for its respective coverage area. The coverage area of ​​an access point can be divided into sectors that constitute only a part of that coverage area. The wireless communication system may include different types of base stations (e.g., macro base stations, micro base stations, or pico base stations). Base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. Base stations may be associated with the same or different access networks or operator deployments. The coverage areas of different base stations (including coverage areas of the same or different types of base stations, coverage areas using the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.

[0113] Communication links in a wireless communication system may include an uplink for carrying uplink (UL) transmissions (e.g., from terminal 11 to network device 12) or a downlink for carrying downlink (DL) transmissions (e.g., from network device 12 to terminal 11). UL transmissions may also be referred to as reverse link transmissions, and DL transmissions may also be referred to as forward link transmissions. Downlink transmissions may be carried out using licensed frequency bands, unlicensed frequency bands, or both. Similarly, uplink transmissions may be carried out using licensed frequency bands, unlicensed frequency bands, or both.

[0114] This invention introduces an intelligent, endogenous model parameter transmission method. By integrating intelligence as part of the base station and combining it with wireless data transmission functions, model parameters can be transmitted faster and more reliably. This achieves the organic integration of model algorithms, interaction processes, and wireless communication, enabling the base station to achieve self-optimization, self-evolution, and self-generation.

[0115] Specifically, this invention provides a method for transmitting AI-native data. The data to be transmitted includes two types, referred to as first data and second data, respectively. The first data is the control signaling for the AI ​​task (referred to as AI-C in this document), which may include configurations for establishing end-to-end AI, configurations for task interruption or termination, management information for the AI ​​model, configuration information for data acquisition, and other information controlling the correct operation of the end-to-end AI task. The second data is AI model parameters and / or data acquisition information (referred to as AI-U in this document), which may include synchronization information between the network and the terminal during AI model training, such as parameter updates under federated learning, model transfer information in transfer learning, or AI model transmission in the case of model segmentation in distributed AI, and also includes pre-processed data acquisition information and / or data labeling information.

[0116] Please refer to Figure 2 and Figure 3 The present invention provides a data transmission method, which, when applied to a base station, includes:

[0117] Step 21: The MAC layer of the base station interacts with the terminal through a MAC control packet or a MAC control unit to exchange first data and / or second data, wherein the first data is control signaling for the artificial intelligence (AI) task, and the second data is AI model parameters and / or data acquisition information.

[0118] Traditional AI data transmission involves the core network, access network, and terminal. However, in the case of AI being inherent, intelligence is ubiquitous in the network. The wireless side also possesses local intelligent agents. To improve the efficiency and reliability of AI data transmission, this invention employs a novel data transmission method.

[0119] Through the above steps, embodiments of the present invention can achieve reliable transmission of AI data by exchanging first data and / or second data between the terminal and the base station through a MAC control packet or MAC control unit.

[0120] like Figure 3 As shown, the base station also includes a first AI function module for implementing AI functions, and the first data and the second data may be generated by the first AI function module.

[0121] In step 21 above: the MAC layer of the base station receives the first MAC control packet or MAC control unit sent by the terminal, obtains the first data and / or the second data encapsulated in the first MAC control packet or MAC control unit, and sends it to the first AI function module;

[0122] And / or,

[0123] The MAC layer of the base station receives first data and / or second data sent by the first AI function module, encapsulates the first data and / or second data sent by the first AI function module into a second MAC control packet or MAC control unit, and then sends it to the terminal.

[0124] In this embodiment of the invention, the MAC layer multiplexes the first and / or second data to be transmitted into a transport block (TB) and delivers it to the physical layer (PHY). The physical layer receives the first and / or second data sent by other devices, demultiplexes the first and / or second data, and submits it to the first AI function module. The MAC layer provides data transmission services for receiving the first and second data generated by the first AI function module. On the network side, for the first and / or second data generated by the first AI function module, the MAC layer forms MAC control packets or control units according to these data and sends them to the terminal side through the physical layer; the receiving terminal side receives the MAC control packets or control units through the physical layer, demultiplexes them, and submits them to the terminal's second AI function module. On the terminal side, for the first and / or second data generated by the second AI function module, the MAC layer forms MAC control packets or control units according to these data and sends them to the network side through the physical layer; the network side receives the MAC control packets or control units through the physical layer, demultiplexes them, and submits them to the network's first AI function module. This method effectively reduces the number of processing units involved in AI data transmission and reduces the latency of AI data transmission. Simultaneously, mechanisms such as HARQ in the MAC layer can also ensure data reliability.

[0125] Specifically, the first data includes at least one of the following categories of data packets:

[0126] a) AI connection establishment request signaling.

[0127] The AI ​​connection establishment request is usually a data packet sent by the terminal to the network. It is used by AI-capable terminals within the network to actively report the AI ​​capabilities they support, which is then used to establish an AI connection.

[0128] b) Signaling for establishing an AI connection.

[0129] This data packet is sent from the network to the terminal, and includes the terminal's user ID, used to establish an AI connection between the network and the terminal. The base station assigns a user ID to the terminal corresponding to the AI ​​connection; this user ID is a unique identifier that distinguishes the terminal from the AI's intrinsic module.

[0130] c) Signaling for establishing end-to-end AI tasks.

[0131] This data packet is sent from the network side to the terminal, instructing the terminal to establish the corresponding AI task according to the network side's requirements. The first data segment may contain one or more identifiers such as the task ID, AI model type, initial parameter configuration, user ID, data collection requirements and reporting configuration, and data preprocessing method. The task ID is used to distinguish different AI tasks; the task ID carried in this data packet represents the identifier of the end-to-end AI task to be established. The AI ​​model type and initial configuration parameter configuration indicate the model used by the current AI task. If the terminal does not have model information, it obtains the corresponding model by receiving the initial configuration. The user ID refers to the user ID used in establishing the AI ​​connection.

[0132] d) Stop or interrupt signaling for end-to-end AI tasks.

[0133] This type of MAC control packet or MAC control unit is a data packet sent from the network side to the terminal to instruct the terminal to stop ongoing AI tasks, including AI model calculations and data acquisition. The data packet includes information such as the task ID and user ID.

[0134] e) Release signaling for AI connection.

[0135] This type of MAC control packet or MAC control unit is a data packet sent by the terminal to the network to instruct the network that the UE wants to release the AI ​​connection. After receiving the AI ​​connection release message, the network stops the AI ​​task running for the user and releases the UE's user ID.

[0136] f) Management signaling for AI models.

[0137] g) Configuration signaling for data acquisition.

[0138] The second data includes at least one of the following categories:

[0139] a) Synchronization information between the base station and the terminal during AI model training.

[0140] This type of MAC control packet or control unit can be sent from the network to the terminal, or from the terminal to the network. It is used for real-time parameter synchronization between the network and the terminal. For example, in federated learning, the terminal reports local model parameters to the network, and the network generates global model parameters and sends them to the terminal.

[0141] b) Preprocessed collected data and / or tag information.

[0142] These MAC control packets or control units are sent from the terminal to the network, or vice versa. According to the data acquisition configuration in the end-to-end task setup, the terminal or network generates corresponding data acquisition packets and sends them to the peer. The data acquisition packets carry the task ID corresponding to the data acquisition, the model type, the user ID, and the data acquisition type ID (determined by the initial configuration in the end-to-end task setup). The terminal sends the data according to the data processing requirements and format. For example, data acquisition includes, but is not limited to, raw data reporting, pre-processed data reporting, and data that has undergone partial model processing.

[0143] In this embodiment of the invention, there are two transmission methods for MAC control packets or MAC control units. As the first transmission method, this embodiment introduces a format for MAC control packets or control units (referred to as the first format for ease of description). Both the first data and the second data are encapsulated in this format of MAC control packets or control units. When the MAC at the other end receives the first format MAC control packet or control unit, it parses out the corresponding first data and / or second data and submits it to the AI ​​function module.

[0144] Specifically, such as Figure 4 As shown, the MAC control package or MAC control unit of the first format includes first format indication information, data length indication information, first data and / or second data, wherein the first format indication information is used to indicate that the MAC control package or MAC control unit carries the first data and / or second data.

[0145] Thus, in step 21 above, the MAC layer of the base station can determine the first format according to the first format indication information in the first MAC control packet or MAC control unit; parse the first MAC control packet or MAC control unit according to the first format to obtain the first data and / or the second data encapsulated therein; and encapsulate the first data and / or the second data sent by the first AI function module into the second MAC control packet or MAC control unit according to the first format, and then send it out through the physical layer.

[0146] As a second transmission method, embodiments of the present invention can introduce corresponding MAC control packets or control units for different categories of first data / second data. In this case, both the first MAC control packet or MAC control unit and the second MAC control packet or MAC control unit include format indication information; the format indicated by the format indication information corresponds to the category of the first data and / or second data encapsulated in the respective MAC control packet or MAC control unit.

[0147] Thus, in step 21 above, the MAC layer of the base station can determine the first target format according to the format indication information in the first MAC control packet or MAC control unit; and parse the first MAC control packet or MAC control unit according to the first target format to obtain the first data and / or second data encapsulated therein.

[0148] In step 21 above, the MAC layer of the base station can also determine the corresponding second target format according to the type of the first data and / or the second data packet sent by the first AI function module; and encapsulate the first data and / or the second data sent by the first AI function module into a second MAC control packet or MAC control unit according to the second target format, wherein the format indication information in the second MAC control packet or MAC control unit indicates the second target format.

[0149] The following provides examples illustrating the format of the MAC control packet or MAC control unit involved in the second transmission method described above. Here, the second transmission method includes, for example... Figures 5 to 11 The seven formats shown are respectively called the second format, the third format, ... the eighth format.

[0150] A) The second format corresponds to the AI ​​connection establishment request signaling;

[0151] Here, the second-format MAC control packet or control unit is sent from the terminal to the network. The terminal receives the first message from the second AI function module (this message is used by the terminal to send an AI connection request to the base station), adds a second-format instruction, assembles a second-format MAC control packet or control unit, and sends it to the network through the physical layer. The network receives the TB block containing the second-format MAC control packet or control unit, demultiplexes it according to the second-format instruction to obtain the first message, and delivers it to the first AI function module.

[0152] B) The third format corresponds to the AI ​​connection establishment signaling.

[0153] Here, after receiving the second-format control packet or control unit identifier, the MAC on the network side adds a third-format identifier and / or assigns a user identifier for AI connection to the terminal, and notifies the first AI function module of the identifier. The first AI function module then sends a second message (used by the network to initiate AI connection establishment to the terminal) to the MAC. The third-format MAC control packet or control unit is sent from the network to the terminal. Upon receiving the second message from the first AI function module, the network adds a third-format instruction to assemble a third-format MAC control packet or control unit, which is then sent to the terminal through the physical layer. The terminal receives the TB block containing the third-format MAC control packet or control unit, demultiplexes it according to the third-format instruction to obtain the second message, and delivers it to the second AI function module.

[0154] C) The fourth format corresponds to the establishment signaling of the end-to-end AI task.

[0155] Here, the fourth-format MAC control packet or control unit is sent from the network to the terminal. On the network side, the MAC receives the third message (used for terminal task AI establishment) from the first AI function module, adds the fourth-format identifier and / or the user identifier for AI connection and / or the task identifier / data length marker, forming the fourth-format MAC control packet or control unit, which is then sent to the terminal through the physical layer. The terminal receives the TB block containing the fourth-format MAC control packet or control unit, demultiplexes it according to the fourth-format instructions to obtain the third message, and delivers it to the second AI function module.

[0156] D) The fifth format corresponds to the synchronization information between the base station and the terminal during the AI ​​model training process.

[0157] Here, the fifth-format MAC control packet or control unit can be sent from the network to the terminal, or from the terminal to the network. At the sending end, the MAC receives the fourth message (used for model and parameter synchronization, e.g., in federated learning, the terminal reports local model parameters to the network, which then generates global model parameters and sends them to the terminal) from its local AI function module. It adds a fifth-format identifier and / or a user identifier for AI connection and / or a task identifier and / or data length marker to form a fifth-format MAC control packet or control unit, which is then sent to the receiving end through the physical layer. The receiving end MAC receives the TB block containing the fifth-format MAC control packet or control unit, demultiplexes it according to the fifth-format instructions to obtain the fourth message, and delivers it to its local AI function module.

[0158] E) The sixth format corresponds to the preprocessed acquired data and / or tag information.

[0159] Here, the sixth-format MAC control packet or control unit can be sent from the network to the terminal, or from the terminal to the network. At the sending end, the MAC receives the fifth message (used to transmit data acquisition results) from its local AI function module, adds a sixth-format identifier and / or a user identifier for AI connection and / or a task identifier and / or a data acquisition identifier and / or data length to form a sixth-format MAC control packet or control unit, and sends it to the receiving end through the physical layer. The receiving end MAC receives the TB block containing the sixth-format MAC control packet or control unit, demultiplexes it according to the sixth-format instructions to obtain the fifth message, and delivers it to its local AI function module.

[0160] F) The seventh format corresponds to the stop or interrupt signaling for end-to-end AI tasks.

[0161] Here, the seventh-format MAC control packet or control unit is sent from the network to the terminal. At the sending end, the MAC receives the sixth message from the first module (used to stop ongoing AI tasks such as model calculations or data acquisition), adds a seventh-format identifier and / or a user identifier for AI connection and / or a task identifier and / or data length marker, assembles a seventh-format MAC control packet or control unit, and sends it to the receiving end through the physical layer. The receiving end MAC receives the TB block containing the seventh-format MAC control packet or control unit, demultiplexes it according to the seventh-format instructions to obtain the sixth message, and delivers it to the first module.

[0162] G) The eighth format corresponds to the release signaling of the AI ​​connection.

[0163] Here, the eighth-format MAC control packet or control unit is sent from the terminal to the network. At the sending end, the MAC receives the seventh message from the first module (e.g., used to instruct the network that the UE wants to release the ongoing AI task such as model calculation or data acquisition), adds the eighth-format identifier and / or the user identifier and / or data length for the AI ​​connection, assembles the eighth-format MAC control packet or control unit, and sends it to the receiving end through the physical layer. The receiving end MAC receives the TB block containing the eighth-format MAC control packet or control unit, demultiplexes it according to the eighth-format instructions to obtain the seventh message, and delivers it to the first module. After receiving the eighth-format MAC control packet or control unit data, the first module stops the AI ​​task running for that user and releases the UE's user ID.

[0164] For example, the first target format can be a second format, a fifth format, a sixth format, or an eighth format; the second target format can be a third format, a fourth format, a fifth format, a sixth format, or a seventh format.

[0165] from Figures 5 to 11 It can be seen that each format of MAC control packet or MAC control unit includes format indication information, data length indication information, the first data and / or the second data; wherein, the third, fourth, fifth, sixth, seventh and eighth formats also include a user identifier for indicating AI connection; the fourth, fifth, sixth and seventh formats also include a task ID for indicating AI task; the sixth format also includes a data acquisition ID.

[0166] In addition, in the second transmission method described above, if the first target format is determined to be the second format based on the format indication information in the first MAC control packet or MAC control unit, the MAC layer of the base station can also assign a user identifier to the terminal to indicate the AI ​​connection, and send the user identifier and the AI ​​connection establishment request signaling to the first AI function module; and after receiving the AI ​​connection establishment signaling sent by the first AI function module, the MAC layer of the base station encapsulates the second MAC control packet or MAC control unit including the format indication information, the user identifier, the data length indication information and the AI ​​connection establishment signaling, and then sends it to the peer device through the physical layer.

[0167] As can be seen from the above, the data transmission method provided by the embodiments of the present invention can reduce the latency of AI data transmission and ensure the reliability of data transmission. In addition, the architecture can make full use of the AI ​​capabilities of the terminal and improve the end-to-end AI capabilities.

[0168] Please refer to Figure 12 The present invention provides a data transmission method, which, when applied to a terminal, includes:

[0169] Step 121: The MAC layer of the terminal interacts with the base station with first data and / or second data through a MAC control packet or a MAC control unit, wherein the first data is control signaling for an artificial intelligence (AI) task, and the second data is AI model parameters and / or data acquisition information.

[0176] In the first transmission method described above, in step 121, the MAC layer of the terminal can determine the corresponding first target format based on the type of the first data and / or second data packet sent by the second AI function module; according to the first target format, encapsulate the first data and / or second data sent by the second AI function module into a first MAC control packet or MAC control unit, wherein the format indication information in the first MAC control packet or MAC control unit indicates the first target format; and, according to the format indication information in the second MAC control packet or MAC control unit, determine a second target format; according to the second target format, parse the second MAC control packet or MAC control unit to obtain the first data and / or second data encapsulated therein.
