[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] The terms "first," "second," etc., used in the embodiments of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products, or devices. Additionally, the use of "and / or" in this application indicates at least one of the connected objects, such as A and / or B and / or C, representing seven possibilities: including A alone, B alone, C alone, and the presence of both A and B, both B and C, both A and C, and the presence of A, B, and C.

[0030] Please see Figure 1 , Figure 1 This is one of the flowcharts illustrating a wireless bearer establishment method provided in an embodiment of this application, such as... Figure 1 As shown, it includes the following steps:

[0031] Step 101: The base station sends an AI connection establishment message to the terminal device. The AI ​​connection establishment message includes a configuration message for the AI ​​data wireless bearer.

[0032] The terminal devices involved in this application embodiment can be devices that provide voice and / or data connectivity to users, handheld devices with wireless connectivity, or other processing devices connected to a wireless modem. The names of the terminal devices may differ in different systems; for example, in a 5G system, a terminal device can be called User Equipment (UE). Wireless terminal devices can communicate with one or more core networks (CNs) via a Radio Access Network (RAN). Wireless terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones) and computers with mobile terminal devices, for example, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the RAN. Examples include Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), Redcap terminals, and other devices. Wireless terminal equipment can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, or user device, but is not limited to these terms in the embodiments disclosed herein.

[0033] It is understood that the aforementioned AI connection establishment message is used to establish the AI ​​connection and AI data wireless bearer between the aforementioned base station and the aforementioned terminal device. Specifically, the aforementioned AI connection establishment message is a Radio Resource Control (RRC) signaling message.

[0034] Furthermore, in a wireless network, end-to-end AI connections can be triggered by either the terminal device or the network element where the module responsible for the AI ​​task resides. This network element can be a base station, core network equipment, or a new network element. If the module is located at the base station, it can be triggered by the base station; if it is located in the core network or a new network element, it can be triggered by the network element itself, and the AI ​​connection is established through the access network and the terminal device. When the module responsible for the AI ​​task is located at the base station, the establishment of the AI ​​data wireless bearer can be achieved by establishing an AI connection. When the module is located in the core network or a new network element, the AI ​​connection establishment includes the establishment of the AI ​​data wireless bearer and the connection establishment from the base station to the core network.

[0035] Step 102: The base station receives an AI connection establishment completion message sent by the terminal device in response to the configuration message of the AI ​​data radio bearer. The AI ​​connection establishment completion message is used to indicate that the AI ​​data radio bearer has been established.

[0036] It is understandable that, since the protocol layer controlling AI connections may differ from existing RRC, SDAP, and UPF, and the data transmitted in AI connections differs in type and transmission requirements from existing data plane and control plane data, the required transmission methods and data bearer modes also differ. In this application, the aforementioned AI data wireless bearer can be used to transmit AI data. Specifically, AI data may include AI-related data and signaling, such as AI task configuration and control information, AI model and parameter information, and AI acquisition data.

[0037] In this embodiment, the base station sends an AI connection establishment message to the terminal device. The AI ​​connection establishment message includes a configuration message for the AI ​​data wireless bearer. The base station receives an AI connection establishment completion message sent by the terminal device in response to the configuration message for the AI ​​data wireless bearer. The AI ​​connection establishment completion message indicates that the AI ​​data wireless bearer has been established, meaning that the AI ​​data wireless bearer can be established based on the AI ​​connection between the base station and the terminal device. The AI ​​data interaction between the base station and the terminal device can be achieved through the AI ​​data wireless bearer, thereby improving the AI ​​data transmission effect between the base station and the terminal device.

[0038] Optionally, before the base station sends the AI ​​connection establishment message to the terminal device in step 101, the method may further include the following steps:

[0039] The base station receives the AI ​​connection request message sent by the terminal device;

[0040] The AI ​​connection establishment message is a message sent by the base station to the terminal device in response to the AI ​​connection request message.

[0041] In some embodiments, the AI ​​connection is triggered by the terminal device sending an AI connection request message to the base station, and then the base station can respond to the AI ​​connection request message sent by the terminal device by sending an AI connection establishment message to the terminal device.

[0042] In this embodiment, the base station can receive an AI connection request message sent by the terminal device, and in response to the AI ​​connection request message, send an AI connection establishment message to the terminal device, thereby realizing the establishment of the AI ​​data wireless bearer and expanding the applicable scenarios for the establishment of the AI ​​data wireless bearer.

[0043] Optionally, the AI ​​data radio bearer belongs to the signaling radio bearer category.

[0044] In some embodiments, the AI ​​data radio bearer established above can be a signaling radio bearer (SRB). It is understood that the AI ​​data radio bearer can be used to carry data related to the establishment of AI connection. That is, the AI ​​data radio bearer is a signaling radio bearer that is different from the existing SRB0, SRB1, SRB2 and SRB3.

[0045] Optionally, the configuration message for the AI ​​data wireless bearer includes a data transmission set, which includes multiple transmission modes and the data transmission capability corresponding to each transmission mode;

[0046] The data transmission capability is used by the base station and the terminal device to determine a target transmission mode, which is the transmission mode used during the transmission of AI data between the base station and the terminal device.

[0047] It is understood that after the base station sends the configuration message of the AI ​​data wireless bearer to the terminal device, the terminal device can save the configuration message of the AI ​​data wireless bearer and use a transmission mode that matches the transmitted AI data for transmission during subsequent interactions between the base station and the terminal device. Whether the transmission mode matches can be determined based on the corresponding data transmission capability. For example, the data transmission capability corresponding to each transmission mode may include the supported bandwidth, data transmission period or latency, etc. The appropriate transmission mode is selected for transmission according to the data transmission capability. Specifically, for example, the matching data transmission capability can be selected from the above data transmission set according to the content characteristics of the AI ​​data to be transmitted (such as bandwidth requirements, latency requirements and data transmission period, etc.), thereby determining the transmission mode.

[0048] In this embodiment, the configuration message of the AI ​​data wireless bearer includes a data transmission set, which includes multiple transmission modes and the data transmission capabilities corresponding to each transmission mode. Thus, during the data interaction between the base station and the terminal device, a transmission mode can be determined based on the data transmission capabilities corresponding to each transmission mode in the data transmission set, thereby improving the transmission effect of data interaction.

[0049] Optionally, the AI ​​data includes a target transmission mode identifier, which is used to identify the target transmission mode.

[0050] In some embodiments, during the AI ​​data interaction between the base station and the terminal device, after the sending end (which can be the base station or the terminal device) selects a transmission mode according to the AI ​​data packet to be sent, it can carry a transmission mode identifier in the data packet header to identify the transmission mode used. The receiving end then receives the data packet according to the transmission mode identifier and the configuration of the transmission mode. Specifically, the transmission mode identifier can be introduced into the header of the Physical Downlink Control Channel (PDCCH) or Media Access Control (MAC) packet corresponding to the data packet to achieve data packet parsing. Furthermore, the transmission mode identifier can correspond to a transmission mode and data transmission capability.

[0051] In this embodiment, the AI ​​data includes a target transmission mode identifier, which is used to identify the target transmission mode. That is, when the base station and the terminal device realize AI data interaction based on the AI ​​data wireless bearer, the target transmission mode can be determined by the target transmission mode identifier, so that both parties can realize data sending and receiving based on the target transmission mode.

[0052] Optionally, the data transmission set further includes configuration information for each transmission mode, wherein the configuration information for each transmission mode includes at least one of the following:

[0053] Transmission mode identifier, encryption / decryption configuration information, and retransmission configuration information.

[0054] It is understood that the aforementioned transmission mode identifier is used to identify the transmission mode; the aforementioned encryption / decryption configuration information is used to indicate whether encryption / decryption is required when transmitting data using each transmission mode, and the algorithms and parameter information used for encryption / decryption; the aforementioned retransmission configuration information is used to indicate whether retransmission is required when transmitting data using each transmission mode. Specifically, for example: when the transmitted AI data is AI model configuration parameters, these parameters are used for model training after being transmitted to the other end, so error-free transmission is crucial. Therefore, a transmission mode with retransmission enabled can be selected for data transmission. However, for AI data acquisition parameters, the accuracy of model training is not significantly affected even if some data acquisition parameters are not transmitted correctly. Therefore, to quickly complete data interaction and thus quickly complete model training, a transmission mode without retransmission enabled can be selected for data transmission. As another example: for privacy data, a transmission mode with encryption / decryption enabled can be selected for transmission.

[0055] Optionally, each transmission mode may also include at least one of the following:

[0056] The configuration includes the serial number (SN) length, reordering settings, and the configurations for Hybrid Automatic Repeat Request (HARQ) and Automatic Repeat Request (ARQ). This allows the data to be transmitted according to the selected transmission mode during AI data interaction between the base station and the terminal device.

[0057] In this implementation, the configuration information for each transmission mode includes at least one of the following: transmission mode identifier, encryption / decryption configuration information, and retransmission configuration information. That is, the appropriate transmission mode can be determined for transmitting AI data based on the configuration information of each transmission mode in the data transmission set.

[0058] Optionally, the data transmission set further includes:

[0059] Priority information for each transmission mode.

[0060] In this embodiment, when AI data is transmitted between the base station and the terminal device via AI data wireless bearer, a matching transmission mode and the priority information corresponding to the transmission mode can be determined, thereby determining the corresponding logical channel priority when uplink data is sent.

[0061] The various optional implementation methods described in the embodiments of this application can be combined with each other or implemented individually without conflict. The embodiments of this application do not limit this.

[0062] Please see Figure 2 , Figure 2 This is a flowchart illustrating another wireless bearer establishment method provided in an embodiment of this application, as shown below. Figure 2 As shown, it includes the following steps:

[0063] Step 201: The terminal device receives an AI connection establishment message sent by the base station, wherein the AI ​​connection establishment message includes a configuration message for the AI ​​data wireless bearer.

[0064] Step 202: In response to the configuration message of the AI ​​data wireless bearer, the terminal device sends an AI connection establishment completion message to the base station. The AI ​​connection establishment completion message is used to indicate that the AI ​​data wireless bearer has been established.

[0065] Optionally, before the terminal device receives the AI ​​connection establishment message sent by the base station in step 201, the method may further include the following steps:

[0066] The terminal device sends an AI connection request message to the base station;

[0067] The AI ​​connection establishment message is a message sent by the base station to the terminal device in response to the AI ​​connection request message.

[0068] Optionally, the configuration message for the AI ​​data wireless bearer includes a data transmission set, which includes multiple transmission modes and the data transmission capability corresponding to each transmission mode;

[0069] The data transmission capability is used by the base station and the terminal device to determine a target transmission mode, which is the transmission mode used during the transmission of AI data between the base station and the terminal device.

[0070] Optionally, the AI ​​data includes a target transmission mode identifier, which is used to identify the target transmission mode.

[0071] Optionally, the data transmission set further includes configuration information for each transmission mode, wherein the configuration information for each transmission mode includes at least one of the following:

[0072] Transmission mode identifier, encryption / decryption configuration information, and retransmission configuration information.

[0073] Optionally, the data transmission set further includes:

[0074] Priority information for each transmission mode.

[0075] Optionally, the AI ​​data radio bearer belongs to the signaling radio bearer category.

[0076] It should be noted that this embodiment is as a comparison with... Figure 1 The implementation methods of the terminal devices corresponding to the illustrated embodiments can be found in the following examples. Figure 1 The relevant descriptions in the illustrated embodiments will not be repeated here to avoid repetition.

[0077] The various optional implementation methods described in the embodiments of this application can be combined with each other or implemented individually without conflict. The embodiments of this application do not limit this.

[0078] For ease of understanding, the specific implementation method is as follows:

[0079] This application provides a flowchart illustrating a wireless bearer establishment method, as shown in the embodiments below. Figure 3 As shown, the specific process includes the following:

[0080] Step 31: The UE sends an AI connection set up request to the base station, requesting the base station to establish an AI connection;

[0081] AI connectivity is an end-to-end connection, such as Figure 3 As shown, the AI ​​connection can be triggered by the terminal device or by the network element where the module responsible for the AI ​​task resides. The network element where the module responsible for the AI ​​task resides can be an access network element (base station) or a core network element. If the network element where the module responsible for the AI ​​task resides is located in the core network, the core network can establish an AI connection with the terminal device through the access network. Step 31 is optional and corresponds to the case where the AI ​​connection is triggered by the terminal device.

[0082] Step 32: The base station sends an AI connection setup message to the UE. AI connection setup can be achieved in two ways:

[0083] Method 1: The base station establishes a new SRB for AI data transmission. This SRB uses a new type of SRB, for example, establishing SRB4 for transmission. This SRB4 only carries data related to the establishment of the AI ​​connection.

[0084] Method 2: The base station establishes a new radio bearer to the UE. The configuration of the new radio bearer includes: a set of data transmission modes, which includes multiple data transmission modes and the data transmission capabilities corresponding to each data transmission mode. The data transmission capabilities corresponding to each data transmission mode include one or more of the following: supported bandwidth, data transmission period, and latency.

[0085] By configuring multiple data transmission modes and corresponding data transmission capabilities, the network can adaptively select a data transmission mode from the data transmission set according to the type of AI-transmitted data packets. Each data transmission mode includes a set of data transmission mode configurations, such as: data transmission mode identifier, encryption / decryption configuration, SN length, reordering configuration, retransmission settings, HARQ and ARQ configurations, and packet retransmission configurations. When sending data, the identifier corresponding to the transmission mode is carried in the data packet header as a marker of the appropriate data transmission mode in the transmission mode set. The receiving end receives data packets according to the data transmission mode configuration based on the data transmission mode identifier.

[0086] Step 33: The UE sends an AI connection set up complete message to the base station to confirm the received model configuration. At this point, the new radio bearer is established.

[0087] For example, when a UE and a base station perform joint AI tasks, an AI connection needs to be established first: the base station initiates the AI ​​connection establishment or the UE initiates an AI connection establishment request. The base station transmits the AI ​​model configuration to UEs that are willing to participate in AI training or inference. Upon receiving the AI ​​connection establishment configuration, if a new SRB (Service Buffer) is established, the UE transmits the configuration under the newly established SRB. The transmitted content includes model distribution information, parameter synchronization information, and data acquisition results. If the AI ​​connection establishment includes a data transmission mode set, the UE saves the corresponding data transmission mode set. During transmission, the appropriate data transmission mode is selected according to the content to be transmitted, ensuring that the transmission requirements of the transmitted content match the data transmission mode of the data transmission mode set. Taking federated learning as an example: if UEs need to perform joint training, the base station first needs to determine which UEs will perform the training task, and then triggers the AI ​​connection establishment process to the corresponding UEs, establishing a new radio bearer. After establishing the new radio bearer, the UE selects an appropriate data transmission mode from the data transmission mode set of the new radio bearer according to the characteristics of the data content to be transmitted, such as bandwidth requirements and latency requirements, and transmits the AI ​​model configuration to the UEs participating in the training through the established new radio bearer. During joint training between the UE and the base station, the UE transmits the training parameters to the base station via a new type of radio bearer. Since errors in some parameters do not significantly affect the overall model, a data transmission mode configured as Radio Link Control Unacknowledged Mode (RLC UM) can be adopted to ensure rapid parameter transmission.

[0088] like Figure 4As shown, AI connectivity is applicable to the transmission of AI-related messages between the UE and the network. On the radio side, radio bearers can be divided into three categories: data radio bearers for the data plane, signaling radio bearers for the signaling plane, and new radio bearers applicable to the intelligent plane. If the receiver is the core network, the radio side delivers the data received in the new radio bearer sequentially to the module responsible for AI tasks via AI connectivity.

[0089] The new radio bearer is established via RRC (Radio Resource Control) messages, such as... Figure 4 As shown, the new wireless bearer can be configured with multiple transmission modes, and the wireless access side node and the core network node establish a connection through the NG-U (user plane interface) channel.

[0090] The data transmitted on the new wireless bearer can include one or more of the following: AI task configuration and control for the network and UE, AI models and parameters, AI data acquisition, etc. The new wireless bearer can be configured with different security and encryption strategies based on the transmission characteristics; the security and encryption strategies for each transmission mode are fixed. For user privacy data, it can be transmitted with encryption enabled and in transmission mode. Different transmission modes can have different retransmission configurations. For transmitting model configuration parameters, after the model configuration is transmitted to the other end, it is used for model training, and error-free transmission needs to be ensured; therefore, retransmission needs to be enabled to ensure error-free transmission of the model configuration. For data acquisition parameters, if some data acquisition parameters are not transmitted correctly, it will not significantly affect the accuracy of model training; therefore, in order to quickly complete data interaction and training, retransmission is not required.

[0091] When sending and receiving data using the same data transmission mode set, the data packet can be parsed by introducing a transmission mode identifier in the physical layer PDCCH or MAC header corresponding to the data packet. The data transmission mode identifier is carried during the establishment of the AI ​​connection and corresponds to a specific data transmission mode and data transmission capability.

[0092] Furthermore, the new radio bearer has priorities. Each transmission mode of the new radio bearer has its own priority, which can be used to determine the corresponding logical channel priority when transmitting uplink data.

[0093] In this embodiment, a novel wireless bearer is established during the AI ​​connection establishment process between the base station and the UE, ensuring the reliability of AI data transmission between the base station and the UE. Furthermore, by configuring a data transmission mode set, AI data with different transmission requirements is mapped to corresponding data transmission modes, and different transmission modes are distinguished by the data packet transmission mode identifier. The base station and the UE can flexibly select a transmission mode from the data transmission mode set based on the data characteristics sent on the current AI connection.

[0094] See Figure 5 , Figure 5 This is a schematic diagram of the structure of a base station provided in an embodiment of this application. Figure 5 As shown, base station 500 includes:
