[0002] Typically, radio bearers include control plane radio bearers and user plane radio bearers.

The network device 110 can provide network coverage for a specific geographical area and can communicate with the terminal device 120 located within that coverage area. The terminal device 120 can access a network, such as a wireless network, through the network device 110. Optionally, the wireless communication system 100 may also include other network entities such as a network controller and a mobility management entity; this embodiment of the application does not limit this.

Optionally, terminal devices can act as base stations. For example, a terminal device can act as a dispatching entity, providing sidelink signals between terminal devices in vehicle-to-everything (V2X) or device-to-device (D2D) systems. For instance, cellular phones and cars communicate with each other using sidelink signals. Cellular phones and smart home devices communicate without relaying communication signals through base stations.

[0027] In this embodiment, the network device can be a device used for communicating with a terminal device. The network device can be an access network device or a wireless access network device. For example, the network device can be a base station. A base station can broadly encompass, or be replaced by, various names including: NodeB, evolved NodeB (eNB), next-generation NodeB (gNB), relay station, access point, transmitting and receiving point (TRP), transmitting point (TP), femtocell, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), centralized unit-control plane (CU-CP), centralized unit-user plane (CU-UP), positioning node, etc. A base station can be a macro base station, micro base station, relay node, donor node, or similar entities, or a combination thereof. A base station can also refer to a communication module, modem, or chip installed within the aforementioned equipment or device. A base station can also be a mobile switching center, or a device that performs base station functions in device-to-device (D2D), vehicle-to-everything (V2X), and machine-to-machine (M2M) communications, a network-side device in a 6G network, or a device performing base station functions in future communication systems. A base station can support networks using the same or different access technologies. The embodiments of this application do not limit the specific technologies or device forms used in the network equipment. A base station can support networks using the same or different access technologies. The embodiments of this application do not limit the specific technologies or device forms used in the network equipment.

[0028] Furthermore, base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move depending on the location of the mobile base station. In other examples, a helicopter or drone can be configured as a device to communicate with another base station.

[0030] Network devices and terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can also be deployed in the air on airplanes, balloons, and satellites. This application does not limit the scenario in which the network devices and terminal devices are located.

[0031] It should be understood that all or part of the functions of the communication device in the embodiments of this application can also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform such as a cloud platform.

[0032] Typically, a radio bearer (RB) includes a control plane radio bearer (also called a control plane bearer) and a user plane radio bearer (also called a user plane bearer). The control plane radio bearer, also known as the signaling radio bearer (SRB), is mainly used to transmit messages from the RRC protocol layer and / or NAS protocol layer. Each RRC message can transmit a maximum of approximately 9KB of data. The user plane radio bearer, also known as the data radio bearer (DRB), is established on the air interface by the access network equipment triggered by the core network equipment. Typically, one or more data radio bearers are triggered by the access network equipment using a session as the basic unit. Once established, a data radio bearer can continuously transmit data under conditions of sufficient air interface resources; therefore, it is generally considered that there is no upper limit to the data transmission capacity of a data radio bearer.

[0033] With the gradual application of AI technology in communication systems, the types of data transmission services in these systems are undergoing significant changes. This has expanded from single application-layer data transmission services to include both application-layer data transmission services and data transmission services within the communication system itself, such as AI model transmission tasks and model training dataset transmission tasks. These new service types typically involve large data transmission volumes. When transmitting such large amounts of data via data radio bearers, if the core network equipment triggers the access network equipment to establish data radio bearer resources, this approach adds extra signaling interaction between the core network and access network equipment. Furthermore, always triggering access network equipment to establish air interface radio bearer resources via the core network equipment also causes additional communication latency, reducing the data communication efficiency between terminal equipment and access network equipment. Moreover, related technologies cannot associate data radio bearers with access stratum (AS) related data transmission tasks, which greatly limits the scope of data radio bearer applications. Relying solely on signaling radio bearers to transmit large amounts of data is inefficient and may even lead to congestion of the signaling radio bearer channel. In conclusion, neither data wireless bearer nor signaling wireless bearer in the relevant technologies can achieve efficient data transmission between various nodes within a communication system without technological innovation.

[0034] Therefore, in this embodiment of the application, the terminal device receives one or more first information messages sent by the network device. These first information messages are used to establish one or more radio bearers. Since the first information messages include radio bearer identification information for the established radio bearers or groups of radio bearers and are associated with data transmission task types, the terminal device can determine on which radio bearers to transmit data corresponding to which task type. In other words, a mapping between tasks and bearers is achieved.

[0035] The models mentioned below include, for example, AI models or machine learning (ML) models.

[0036] The embodiments of this application will be described in detail below with reference to Figure 2.

[0037] Figure 2 is a schematic flowchart of a wireless communication method provided in an embodiment of this application. The method shown in Figure 2 can be executed by a terminal device and a network device. The terminal device can be, for example, the terminal device 120 shown in Figure 1, and the network device can be, for example, the network device 110 shown in Figure 1.

[0038] Referring to Figure 2, in step 210, the network device sends one or more first messages to the terminal device.

[0039] Accordingly, in step 220, the terminal device receives one or more first pieces of information sent by the network device.

[0040] The first information is used to establish one or a group of radio bearers. For example, the first information may include radio bearer identification information of the radio bearer, and the first information is associated with the data transmission task type.

[0041] In this embodiment, the established radio bearer can be either a data radio bearer or a signaling radio bearer. That is, the radio bearer established based on the first information can be either a signaling radio bearer or a data radio bearer. In particular, since data radio bearers are more suitable for transmitting large amounts of data—such as model data, model training datasets, model parameters, and terminal device capability information—which often correspond to large data volumes, transmission via data radio bearers is more efficient and can effectively avoid congestion of the signaling radio bearer channel caused by a large number of RRC message segments.

[0042] In this embodiment, the establishment of the data radio bearer can be triggered by either the core network or the access network. This breaks the technical limitation that only core network devices can trigger the establishment of data radio bearer resources, allowing access network devices to establish data radio bearers as needed, increasing the flexibility of data radio bearer resource establishment. Furthermore, access network devices triggering the establishment of data radio bearers significantly improves the efficiency of transmitting large amounts of data between terminal devices and access network devices, offering a significant advantage over data transmission via signaling radio bearers. Especially in mobility scenarios, lossless data transmission can be achieved through the data recovery mechanism of the data radio bearer, while signaling radio bearers in related technologies cannot achieve lossless data transmission in mobility scenarios. Therefore, the technical advantages of data radio bearers over signaling radio bearers are substantial. In addition, the data transmission tasks performed by different radio bearers can be flexibly indicated through the first information, without needing to pre-define in the protocol which bearers are used to transmit which data transmission tasks, thus greatly improving system flexibility.

[0043] The first information is associated with a data transmission task type, indicating which data transmission task type a radio bearer or group of radio bearers established using the first information is used to transmit, or indicating which data transmission task type a radio bearer or group of radio bearers established using the first information is for. The first information is associated with one or more data transmission task types. For example, if the first information is used to establish a radio bearer, then that radio bearer is associated with one or more data transmission tasks; as another example, if the first information is used to establish a group of radio bearers, then that group of radio bearers is associated with one or more data transmission tasks, and radio bearers belonging to the same group are associated with the same data transmission tasks.

[0044] In order to establish the association between the first information and one or more specific data transmission task types, the embodiments of this application provide the following multiple association implementation methods.

[0045] The first method of association implementation: The data transmission task type of the first information association is determined based on the position of the parameter carrying the first information.

[0046] The location of the parameter carrying the first information in the protocol can implicitly indicate the data transmission task type associated with the corresponding first information. In this implementation, the protocol specifies which data transmission task type(s) the parameter carrying the first information is associated with. The association between the parameter carrying the first information and the data transmission task type can be one-to-one or one-to-many. This implementation can also be called the protocol default method or the protocol agreed method.

[0047] As an example, as shown in Table 1, n is a positive integer. The data transmission task type associated with the corresponding first information can be determined by the agreed position of the parameter corresponding to the first information in the protocol. This implementation requires fewer parameters, saving configuration overhead. Specifically, in Table 1, parameter 1 carries first information 1, which is used to establish one or a group of radio bearers associated with data transmission task type 1; parameter 2 carries first information 2, which is used to establish one or a group of radio bearers associated with data transmission task type 2; ...; parameter n carries first information n, which is used to establish one or a group of radio bearers associated with data transmission task type n. The protocol specifies which data transmission task type(s) each parameter is associated with.

[0048] Table 1

[0049] The second method of association is as follows: the data transmission task type associated with the first information is determined based on the value of the wireless bearer identifier information included in the first information.

[0050] When the value of the radio bearer identifier information included in the first information indicates the data transmission task type associated with the corresponding first information, the protocol will stipulate the association relationship between different data transmission task types and radio bearer identifiers with different values. The association relationship between different data transmission task types and radio bearer identifier information with different values ​​can be one-to-one or many-to-one.

[0051] As an example, as shown in Table 2, n is a positive integer. The value of the radio bearer identifier information included in the first information determines the type of data transmission task for which the radio bearer corresponding to the first information was established. This implementation requires fewer parameters, saving configuration overhead. Specifically, in Table 2, first information 1 is associated with the data transmission task corresponding to the radio bearer identifier with value 1, first information 2 is associated with the data transmission task corresponding to the radio bearer identifier with value 2, and so on, with first information n being associated with the data transmission task corresponding to the radio bearer identifier with value n.

[0052] Table 2

[0053] In some other implementations, the second association implementation method and the first association implementation method described above can be combined to obtain a new implementation method. That is, the agreed position of the parameter carrying the first information in the protocol or the value of the radio bearer identification information included in the first information can uniquely determine the data transmission task type of one or a group of radio bearer associations established by the first information. This implementation method can also save configuration overhead.

[0054] The third method of association implementation: The first information includes a first indication information that indicates the data transmission task type associated with the first information.

[0055] The first information also includes first indication information, which is used to indicate the data transmission task type associated with the first information. By indicating the data transmission task type associated with the first information through the first indication information, the data transmission task type associated with the first information is actually explicitly indicated through the first indication information included in the first information.

[0056] As an example, as shown in Table 3, n is a positive integer. The value of the first indication information included in the first information can determine which data transmission task type the radio bearer established by the first information is for transmitting. This implementation method has good flexibility and scalability because it does not require a protocol to specify which first information is fixedly associated with which data transmission task types, nor does it require a protocol to specify which fixed values ​​of radio bearer identification information are associated with which data transmission task types. Compared with the implementation methods shown in Tables 1 and 2, the configuration method of the implementation method shown in Table 3 is more flexible. Each piece of first information in Table 3 is used to establish one or a group of radio bearers, where first information 1 is associated with the data transmission task type indicated by first indication information 1, first information 2 is associated with the data transmission task type indicated by first indication information 2, ..., first information n is associated with the data transmission task type indicated by first indication information n.

[0057] Table 3

[0058] In one implementation, the first indication information is an identification information (e.g., an ID identifier). For example, the value of the first indication information is '0000' to indicate a model training dataset transmission task, '0001' to indicate a model transmission task, '0010' to indicate a model parameter transmission task, '0011' to indicate a terminal device capability information transmission task, and '0100' to indicate a measurement-related data transmission task. As another example, the value of the first indication information is '0000' to indicate a model training dataset transmission task for CSI compressed feedback function, '0001' to indicate a model transmission task for CSI compressed feedback function, '0010' to indicate a model parameter transmission task for CSI compressed feedback function, '0011' to indicate a model training dataset transmission task for beam management function, and '0100' to indicate a model transmission task for beam management function. This application does not limit the actual number of bits occupied by the first indication information, nor does it limit the actual data transmission task type associated with each value of the first indication information; the above are merely examples. This implementation is relatively cost-effective and has good scalability. In another implementation, the first indication information is a first bit string. Each bit in the first bit string is associated with a data transmission task type. For example, a first target bit in the first bit string having a first value (e.g., a first value of '1') indicates that the corresponding radio bearer is used to transmit data corresponding to the data transmission task type associated with that first target bit; a second value (e.g., a second value of '0') indicates that the corresponding radio bearer is not used to transmit data corresponding to the data transmission task type associated with that first target bit. The first target bit can be any bit in the first bit string. In yet another implementation, the first indication information is an enumerated type parameter, where each element of the enumerated type parameter corresponds to a data transmission task type. In yet another implementation, the first indication information is implemented using a selection function (choice{} function), where each value of the choice{} function corresponds to a data transmission task type. In another implementation, the first indication information includes one or more first indication parameters, each of which is associated with a data transmission task type. The protocol will define the data transmission task type associated with different first indication parameters by default (that is, the data transmission task type associated with the first indication parameter can be determined by the predefined position of the corresponding first indication parameter in the protocol).For example, if the first indication parameter is set to a third value (e.g., the third value is 'true'), it means that one or a group of radio bearers associated with the first indication parameter are used to transmit data corresponding to a data transmission task type associated with the first indication parameter. If the first indication parameter is set to a fourth value (e.g., the fourth value is 'false'), it means that one or a group of radio bearers associated with the first indication parameter cannot be used to transmit data corresponding to a data transmission task type associated with the first indication parameter.

[0059] In some implementations, the data transmission task types associated with the first information include model training dataset transmission tasks and / or measurement-related data transmission tasks. The model training dataset is used to train the model. For example, for beam management functions, the terminal device can collect beam-related measurement results over a period of time (e.g., beam-related measurement results include one or more of the following: cell identification information, beam identification information, and beam measurement results). This period of beam measurement results can be called the model training dataset, which is used to train the model for beam management functions. Measurement-related data is typically measurement data obtained by the terminal device through a measurement process using measurement reference signals configured on the network device. Common types of measurement reference signals include synchronization signal block / physical broadcast channel block (SS / PBCH block, SSB), channel state information reference signal (CSI-RS), phase reference symbol (PRS), sensing reference signals, and reference signals for ambient IoT devices. Measurement-related data includes cell-level measurement-related data and / or beam-level measurement-related data. Cell-level measurement-related data includes cell identification information and / or cell measurement results. Beam-level measurement-related data includes one or more of the following: cell identification information, beam identification information, and beam measurement results. The measurement quantities corresponding to the aforementioned measurement results may, for example, include one or more of the following: reference signal received power (RSRP), reference signal received quality (RSRQ), signal to interference plus noise ratio (SINR), received signal strength indication (RSSI), and channel impulse response (CIR).

[0060] The benefits of transmitting model training datasets wirelessly are twofold: First, model training datasets typically record raw sample data, whose characteristics are closer to the actual communication environments experienced by terminal devices. Therefore, transmitting model training datasets allows terminal devices to train models that are closer to reality using raw sample data, and the performance of the models is more likely to meet the needs of actual communication environments. Second, most data types involved in model training datasets (e.g., RSRP measurements) do not have high privacy protection requirements (except for information such as the location of the terminal device). Directly transmitting model training datasets is less likely to leak the trade secrets of the data sender.

[0061] The advantages of transmitting measurement-related data over wireless bearers are twofold: First, the measurement data obtained by a single device (e.g., a terminal device or a network device) through the measurement process is very limited, but the optimization of measurement-related algorithms or the training of measurement-related models generally require a large amount of measurement data. Transmitting measurement-related data over wireless bearers enables measurement data sharing among multiple devices, improving the efficiency of a single device in acquiring measurement-related data. Second, because the data source is relatively random, the generalization of measurement-related data is better (or, in other words, the quality of measurement-related data is higher), making it easier to obtain high-quality optimization algorithms or high-performance models using such data.

[0062] In other implementations, the data transmission task type associated with the first information may include one or more of the following: model transmission task; model parameter transmission task; terminal device capability information transmission task.

[0063] The benefits of transmitting models wirelessly are as follows: If the data receiver uses the received model to perform model training tasks, transmitting the model wirelessly allows the model trainer to train the required model more quickly; if the data receiver uses the received model to perform specific communication functions, it saves the data receiver the work of training that type of model itself. Especially for terminal devices with limited computing power, obtaining the model from the network device is more in line with business reality than training the model itself.

[0064] The beneficial effects of transmitting model parameters over wireless bearers are as follows: If the data receiver of the model parameters uses the received model parameters to perform model training tasks, transmitting model parameters over wireless bearers allows the model trainer to train the required model more quickly; if the data receiver of the model parameters uses the received model parameters to replace existing model parameters, transmitting model parameters over wireless bearers allows the data receiver to quickly update its deployed relevant models, thereby regaining communication gains through the model in a shorter time.

[0065] The beneficial effect of transmitting terminal equipment capability information via data wireless bearer is that it can avoid congestion of signaling wireless bearer when the amount of data contained in the capability information is large.

[0066] As examples, data transmission task types include model training dataset transmission tasks; for example, data transmission task types include measurement-related data transmission tasks; for example, data transmission task types include model transmission tasks; for example, data transmission task types include model parameter transmission tasks; for example, data transmission task types include terminal device capability information transmission tasks; for example, data transmission task types include both model training dataset transmission tasks and measurement-related data transmission tasks; for example, data transmission task types include both model training dataset transmission tasks and model transmission tasks; for example, data transmission task types include both model training dataset transmission tasks and model parameter transmission tasks; for example, data transmission task types include model training... Data transmission tasks include tasks involving the transmission of training datasets and the transmission of terminal device capability information; for example, data transmission task types include measurement-related data transmission tasks and model transmission tasks; for example, data transmission task types include measurement-related data transmission tasks and model parameter transmission tasks; for example, data transmission task types include measurement-related data transmission tasks and terminal device capability information transmission tasks; for example, data transmission task types include model transmission tasks and model parameter transmission tasks; for example, data transmission task types include model transmission tasks and terminal device capability information transmission tasks; for example, data transmission task types include model training ... Data transmission tasks can be categorized into training dataset transmission tasks, measurement-related data transmission tasks, and model transmission tasks. For example, data transmission task types can include model training dataset transmission tasks, measurement-related data transmission tasks, and model parameter transmission tasks. Alternatively, data transmission task types can include model training dataset transmission tasks, measurement-related data transmission tasks, and terminal device capability information transmission tasks. Furthermore, data transmission task types can include model training dataset transmission tasks, model transmission tasks, and model parameter transmission tasks. Additionally, data transmission task types can include model training dataset transmission tasks, model transmission tasks, and terminal device capability information transmission tasks. Data transmission tasks include tasks related to the transmission of capability information of terminal devices; for example, data transmission task types include measurement-related data transmission tasks, model transmission tasks, and model parameter transmission tasks; for example, data transmission task types include measurement-related data transmission tasks, model transmission tasks, and terminal device capability information transmission tasks; for example, data transmission task types include measurement-related data transmission tasks, model parameter transmission tasks, and terminal device capability information transmission tasks; for example, data transmission task types include model transmission tasks, model parameter transmission tasks, and terminal device capability information transmission tasks; for example, data transmission task types include model training dataset transmission tasks, measurement-related data transmission tasks, model transmission tasks, and model parameter transmission tasks.For example, data transmission task types include model training dataset transmission tasks, measurement-related data transmission tasks, model transmission tasks, and terminal device capability information transmission tasks; for example, data transmission task types include model training dataset transmission tasks, measurement-related data transmission tasks, model parameter transmission tasks, and terminal device capability information transmission tasks; for example, data transmission task types include model training dataset transmission tasks, model transmission tasks, model parameter transmission tasks, and terminal device capability information transmission tasks; for example, data transmission task types include measurement-related data transmission tasks, model transmission tasks, model parameter transmission tasks, and terminal device capability information transmission tasks; for example, data transmission task types include model training dataset transmission tasks, measurement-related data transmission tasks, model transmission tasks, model parameter transmission tasks, and terminal device capability information transmission tasks.

[0067] In some implementations, the data transmission task type associated with the first information is defined according to the data type being transmitted. Here, the data type refers to the category of data. However, the category alone cannot effectively distinguish the functional characteristics associated with the data. For example, the data category could be model training datasets, measurement-related data, model-related data, model parameter-related data, or terminal device capability information. Different functional characteristics all involve data in these categories, making this implementation more universal. In other implementations, the data transmission task type associated with the first information is defined according to both the data type being transmitted and the functional characteristics associated with that data type. This implementation indicates both the data category and the specific functional characteristics associated with the data. This approach is more targeted, providing the terminal device with more comprehensive information, thus enabling it to accurately determine which data transmission task types require which wireless bearers for transmission.

[0068] This functional feature may include one or more of the following: channel state information (CSI) compression feedback function; beam management function; positioning function; radio resource management (RRM) measurement function; CSI prediction function; RRM event prediction function; sensing function; beam failure detection (BFD) function; radio link failure (RLF) function; channel estimation function; environmental IoT function; and low-layer / L2-triggered mobility (LTM) function.

[0069] As an example, in the first definition method, the data transmission task type associated with the first information is defined according to the data type being transmitted. In this case, the data transmission task type associated with the first information does not distinguish between the functional characteristics associated with the data type being transmitted. For example, the value range of the data transmission task type associated with the first information can include one or more of the following tasks: model training dataset transmission task, model transmission task, model parameter transmission task, terminal device capability information transmission task, and measurement-related data transmission task. This definition method is highly versatile; the same data transmission channel can be used to transmit the same type of data corresponding to different functional characteristics. The data receiving end can determine the functional characteristics of the transmitted data based on the content contained in the transmitted data. For example, the transmitted data may contain an information field specifically used to indicate the functional characteristics associated with the transmitted data.

[0070] As an example, under the second definition method, the data transmission task type associated with the first information is defined according to the data type being transmitted and the functional characteristics associated with that data type. In this case, the definition of the data transmission task type already considers the functional characteristics associated with the data type being transmitted. The data type and functional characteristics associated with different data transmission task types are agreed upon in the protocol, i.e., agreed upon through the protocol's default method. For example, the value range of the data transmission task type associated with the first information may include one or more of the following tasks: model training dataset transmission task for CSI compressed feedback function; model transmission task for CSI compressed feedback function; model parameter transmission task for CSI compressed feedback function; model training dataset transmission task for beam management function; model transmission task for beam management function; model parameter transmission task for beam management function; model training dataset transmission task for positioning function; model transmission task for positioning function; model parameter transmission task for positioning function; model training dataset transmission task for RRM measurement function; model transmission task for RRM measurement function; model parameter transmission task for RRM measurement function; model training dataset transmission task for CSI prediction function; model transmission task for CSI prediction function; etc. The tasks include: transmitting model parameters for CSI prediction; transmitting model training datasets for RRM event prediction; transmitting model training datasets for sensing; transmitting model parameters for sensing; transmitting model training datasets for BFD; transmitting model training datasets for RLF; transmitting model training datasets for RLF; transmitting model parameters for RLF; transmitting model training datasets for channel estimation; transmitting model parameters for channel estimation; or transmitting capability information for the terminal device. This definition method is more targeted, allowing the terminal device to accurately determine which functional characteristics' data should be transmitted through which radio bearers based on the established radio bearer-associated data transmission task type.

[0071] In one implementation, the data transmission task type adopts the first definition method described above, but the configured wireless bearer is not associated with a specific functional characteristic. In this implementation, as long as the data type (i.e., data category) is the same, data of the same type corresponding to different functional characteristics can be transmitted through the same or the same group of wireless bearers. For example, if the network device configures a group of wireless bearers through the first information and the group of wireless bearers is associated with data of the model training dataset type (i.e., the data transmission task type associated with the group of wireless bearers is the model training dataset transmission task), then regardless of what functional characteristic the terminal device intends to transmit, it can be transmitted through the group of wireless bearers. The data receiving end can determine the functional characteristic corresponding to the transmitted data through the content contained in the transmitted data. For example, there is an information field in the transmitted data specifically used to indicate the functional characteristic associated with the transmitted data, or the functional characteristic associated with the transmitted data can be determined by the physical quantity recorded in the transmitted dataset.

[0072] In another implementation, the data transmission task type is associated with specific functional characteristics of the radio bearer configured using the first definition method described above. In this implementation, since the definition of the data transmission task type does not include the meaning of the functional characteristics, if the network device still wants the terminal device to know the functional characteristics corresponding to the established radio bearer-associated data transmission task type, it needs to separately indicate the functional characteristics corresponding to that data transmission task type to the terminal device through additional indication information (e.g., the second indication information described later). In this way, combining the established radio bearer-associated data transmission task type and the functional characteristics indicated by the second indication information, the terminal device can determine which functional characteristics correspond to which type of data and which radio bearers need to be transmitted. That is, the network device uses the second indication information to indicate the functional characteristics corresponding to the data transmission task type associated with the first information, and the terminal device can determine the functional characteristics corresponding to the data transmission task type associated with the first information based on the second indication information.

[0073] In another implementation, the data transmission task type adopts the second definition method mentioned above. Since the definition of the data transmission task type is already associated with specific functional characteristics, in this implementation, there is no need to separately indicate the functional characteristics associated with the corresponding data transmission task type through additional information. The terminal device can determine which type of data corresponding to which functional characteristic needs to be transmitted through which wireless bearers simply by establishing the data transmission task type associated with the wireless bearer.

[0074] In some implementations, the first information may further include first identification information, which is used to indicate the correlation between multiple radio bearers established based on different first information (i.e., multiple radio bearers can be associated together through the first identification information, and the multiple radio bearers associated together can be called the same group of radio bearers), or the first identification information is used to indicate the group identification information of a group of radio bearers established based on one first information. Wherein, if the first identification information is used to indicate the correlation between multiple radio bearers established based on different first information, then the values ​​of the first identification information in the multiple first information corresponding to the multiple correlated radio bearers are the same. For example, the first identification information is used to indicate the logical number corresponding to the data transmission task associated with the first information, or the first identification information is used to indicate the radio bearer group identifier or data transmission task identifier to which the radio bearer established by the first information belongs. The fact that the values ​​of the logical number, radio bearer group identifier, or data transmission task identifier associated with the radio bearer are the same indicates that the multiple radio bearers established based on different first information are correlated. For example, correlation between radio bearers means that correlated radio bearers perform the same data transmission task.

[0075] As an example, the first information includes radio bearer identification information; for example, the first information includes radio bearer identification information and first indication information; for example, the first information includes radio bearer identification information and second indication information; for example, the first information includes radio bearer identification information and first identification information; for example, the first information includes radio bearer identification information, first indication information, and first identification information; for example, the first information includes radio bearer identification information, second indication information, and first identification information; for example, the first information includes radio bearer identification information, first indication information, and second indication information; for example, the first information includes radio bearer identification information, first indication information, second indication information, and first identification information. It should be noted that when the first information is used to establish a group of radio bearers, the individual bearers in this group of radio bearers can be interconnected. This association can be implicitly indicated by the parameters defined in the first information or explicitly indicated by the first identification information.

[0076] In one implementation, the second indication information is an identification information (e.g., an ID identifier). The protocol stipulates the association between different values ​​of the second indication information and different functional characteristics. For example, the second indication information with a value of '0000' is used to indicate the CSI compression feedback function, a value of '0001' is used to indicate the beam management function, a value of '0010' is used to indicate the positioning function, a value of '0011' is used to indicate the RRM measurement function, a value of '0100' is used to indicate the CSI prediction function, a value of '0101' is used to indicate the RRM event prediction function, a value of '0110' is used to indicate the sensing function, a value of '0111' is used to indicate the BFD function, a value of '1000' is used to indicate the RLF function, a value of '1001' is used to indicate the channel estimation function, and a value of '1010' is used to indicate the terminal device's capability information reporting function. This application embodiment does not limit the actual number of bits occupied by the second indication information, nor does it limit the functional characteristics actually associated with each value of the second indication information; the above are merely examples. This implementation is relatively cost-effective and has good scalability. In another implementation, the second indication information is a second bit string, where each bit is associated with a functional characteristic. The second target bit in the second bit string has a fifth value (e.g., '1') indicating that the corresponding radio bearer is used to transmit data corresponding to the functional characteristic associated with that second target bit; a sixth value (e.g., '0') indicates that the corresponding radio bearer is not used to transmit data corresponding to the functional characteristic associated with that second target bit. The second target bit can be any bit in the second bit string. In yet another implementation, the second indication information is an enumerated type parameter, where each element of the enumerated type parameter corresponds to a functional characteristic. In yet another implementation, the second indication information is implemented using the `choice{}` function, where each value of the `choice{}` function corresponds to a functional characteristic. In another implementation, the second indication information includes one or more second indication parameters, each of which is associated with a functional characteristic. The protocol will define the functional characteristic associated with different second indication parameters by default (i.e., the functional characteristic associated with the second indication parameter can be determined by the predefined position of the corresponding second indication parameter in the protocol). For example, if the value of the second indication parameter is the seventh value (e.g., the seventh value is 'true'), it means that one or a group of radio bearers associated with the second indication parameter is used to transmit data corresponding to the functional characteristic associated with the second indication parameter. If the value of the second indication parameter is the eighth value (e.g., the eighth value is 'false'), it means that one or a group of radio bearers associated with the second indication parameter cannot be used to transmit data corresponding to the functional characteristic associated with the second indication parameter.

[0077] Regarding the first definition method for the aforementioned data transmission task type, where the data transmission task type associated with the first information is defined according to the data type being transmitted, the terminal device cannot determine which functional feature the wireless bearer established based on the first information is for. When different functional features require the transmission of the same type of data (e.g., different functional features require the transmission of model training datasets), the terminal device cannot distinguish which wireless bearers are used to transmit which type of data corresponding to which functional feature(s). This may lead to inconsistencies in the understanding of the transmitted data content between the data sender and receiver during communication, resulting in communication errors (e.g., data being transmitted through the wrong wireless bearer). For example, a network device configures two wireless bearers based on the first information: the first wireless bearer is used to transmit the model training dataset for the CSI compressed feedback function, and the second wireless bearer is used to transmit the model training dataset for the beam management function. However, the terminal device only knows that both wireless bearers are for transmitting model training datasets. To further clarify which functional feature each wireless bearer is used to transmit, the second indication information associated with the corresponding wireless bearer can be used to indicate which functional feature the wireless bearer is used to transmit. In this way, terminal devices and network devices can ensure consistency in their understanding of the data types being transmitted and the data transmission channel resources, thereby avoiding scenarios where data transmission errors occur due to incorrect use of the wireless bearer channel.

[0078] In some implementations, the first information may also include first identification information. The terminal device can determine the correlation between multiple radio bearers established by multiple pieces of first information based on the first identification information, or determine the group identification information of a group of radio bearers established by one piece of first information based on the first identification information. On the one hand, there may be more than one radio bearer performing a data transmission task. In this case, multiple radio bearers can be associated through the first identification information, facilitating the data transmitter to perform data splitting and transmission, and also facilitating the data receiver to perform data merging. That is, if the values ​​of the first identification information associated with at least two configured radio bearers are the same, then these radio bearers can be considered to be used to perform the same data transmission task.

[0079] As an example, as shown in Table 4, the first information includes radio bearer identification information, first indication information, second indication information, and first identification information. Table 4 uses four pieces of first information as an example. The data transmission tasks performed by the first two pieces of first information (i.e., first information 1 and first information 2) are related, and the corresponding first identification information values ​​are both '0010'. Here, the correlation between different radio bearers established by different first information is determined by the value of the first identification information. That is, radio bearers associated with first identification information with the same value are used to perform the same data transmission task, and the radio bearers established by the first two pieces of first information are for performing model training dataset transmission tasks related to beam management functions. The data transmission tasks performed by the latter two pieces of first information (i.e., first information 3 and first information 4) are not related, and the corresponding first identification information values ​​are different, and the data types transmitted are also different. The radio bearer established by first information 3 is for performing model training dataset transmission tasks related to CSI compression feedback functions, while the radio bearer established by first information 4 is for performing model parameter transmission tasks related to CSI compression feedback functions.

[0080] Table 4

[0081] As another example, as shown in Table 5, the first information includes a set of radio bearers corresponding to a radio bearer identification information, a first indication information, a second indication information, and a first identification information (in this case, the first identification information is used to indicate the group identification information of the set of radio bearers established by the first information). Table 5 uses four pieces of first information as an example, each piece of first information establishing a set of radio bearers, and different sets of radio bearers are associated with different data transmission tasks (i.e., at least one of the data type and the functional characteristics of the transmitted data is different). The first identification information (i.e., the group identification information corresponding to a set of radio bearers) can also be included in the second information. In this case, the first identification information is associated with the measurement configuration information included in the second information. For details, please refer to the corresponding section below.

[0082] Table 5

[0083] After introducing the first identification information, on the one hand, the data included in a data transmission task can be transmitted in parallel through more than one wireless bearer (e.g., first information 1 and first information 2 shown in Table 4), reducing the latency of the data transmission task. Since the first identification information associated with wireless bearers that implement the same data transmission task has the same value, the data sender can clearly know which wireless bearers the data corresponding to the data transmission task should be transmitted through. At the same time, the data receiver can also clearly know which wireless bearers the data transmitted on can be associated and processed. The first identification information can clearly indicate the correlation between different wireless bearers. On the other hand, the first identification information can also associate different data transmission tasks, increasing the flexibility of wireless bearer configuration. Although some task types of data need to be transmitted through different wireless bearers (e.g., different task types of data require different quality of service (QoS) management levels), since these data are used for the same purpose (e.g., model training datasets and model parameter data can both be used for model training tasks), associating the data corresponding to the two data transmission task types through the first identification information is more in line with actual needs and avoids the additional complexity caused by the data receiver performing secondary association operations on the data corresponding to different data transmission task types.

[0084] In some implementations, the first information further includes third indication information, which is used to indicate the QoS requirements that the data transmitted on the radio bearer established based on the first information needs to meet. For example, the first information includes radio bearer identification information and third indication information; or, for example, the first information includes radio bearer identification information, first indication information, and third indication information; or, for example, the first information includes radio bearer identification information, second indication information, and third indication information; or, for example, the first information includes radio bearer identification information, first identification information, and third indication information; or, for example, the first information includes radio bearer identification information, first indication information, first identification information, and third indication information; or, for example, the first information includes radio bearer identification information, first indication information, second indication information, first identification information, and third indication information; or, for example, the first information includes radio bearer identification information, first indication information, second indication information, first identification information, and third indication information.

[0085] The third indication information is used for data classification and transmission. For the same data transmission task, the transmitted data itself can be divided into at least two sub-data categories, and different sub-data categories have different QoS requirements. Different sub-data categories can be further transmitted separately through different radio bearers, and the data transmitted on each related radio bearer has different QoS requirements. For example, for a model transmission task, model data can be further divided into model structure data and model parameter data. Among them, model structure data has higher precision requirements and can be transmitted through radio bearers that meet higher QoS requirements. Higher QoS requirements mean lower data fault tolerance, and to achieve lower fault tolerance, the data bit rate often needs to be reduced. Lower data bit rate means greater data transmission latency and lower data transmission efficiency. On the other hand, model parameter data has lower precision requirements than model structure data and can be transmitted through radio bearers that meet medium QoS requirements. Medium QoS requirements, compared to lower QoS requirements, mean higher data fault tolerance. Higher fault tolerance often allows for the use of a relatively higher data bit rate, which means lower data transmission latency and higher data transmission efficiency. It can be seen that the third indication information can realize data classification and transmission, optimizing the resource allocation of data transmission without affecting data transmission quality, resulting in higher data transmission efficiency.

[0086] The technical solutions described above are applicable to both uplink data transmission scenarios (data transmission from terminal devices to network devices) and downlink data transmission scenarios (data transmission from network devices to terminal devices). Specifically, for the uplink data transmission scenario:

[0087] In the first scenario (where the first information is not associated with any data transmission task type), the information content included in the first information cannot determine which type of data corresponding to which functional characteristic the wireless bearer established by the first information is used to transmit. For example, the first information includes wireless bearer identification information; or the first information includes wireless bearer identification information and first identification information; or the first information includes wireless bearer identification information and third indication information; or the first information includes wireless bearer identification information, first identification information, and third indication information, and the position of the parameters carrying the first information and the value of the wireless bearer identification information cannot help the terminal device confirm which type of data corresponding to which functional characteristic the wireless bearer established by the first information is used to transmit.

[0088] In the second scenario (where the first information is associated with one or more data transmission task types, and the data transmission task types are implemented using the first definition method, and the one or more data transmission task types associated with the first information are determined by the parameter position carrying the first information and / or the value of the wireless bearer identification information), the information content included in the first information can help the terminal device confirm what type of data the wireless bearer established by the first information is used to transmit, but it cannot confirm what functional characteristic that type of data corresponds to. For example, the first information includes wireless bearer identification information; or the first information includes wireless bearer identification information and first identification information; or the first information includes wireless bearer identification information and third indication information; or the first information includes wireless bearer identification information, first identification information, and third indication information, and the parameter position carrying the first information and / or the value of the wireless bearer identification information can help the terminal device confirm what type of data the wireless bearer established by the first information is used to transmit, but it cannot confirm what functional characteristic that type of data corresponds to.

[0089] In the third scenario (where the first information is associated with one or more data transmission task types, the data transmission task types are implemented using the first definition method, and the one or more data transmission task types associated with the first information are indicated by the first indication information), the information content included in the first information can help the terminal device confirm which type of data the wireless bearer established by the first information is used to transmit, but it cannot confirm which functional characteristic the data of that task type corresponds to. For example, the first information includes wireless bearer identification information and first indication information; or the first information includes wireless bearer identification information, first indication information, and first identification information; or the first information includes wireless bearer identification information, first indication information, and third indication information; or the first information includes wireless bearer identification information, first indication information, first identification information, and third indication information, wherein the first indication information can help the terminal device confirm which type of data the wireless bearer established by the first information is used to transmit, but it cannot confirm which functional characteristic the data of that type corresponds to.

[0090] For the first scenario, other methods are needed to assist the terminal device in confirming which type of data corresponding to which functional characteristic the wireless bearer established by the first information is used to transmit; for the second and third scenarios, other methods are needed to assist the terminal device in confirming which type of data corresponding to which functional characteristic the wireless bearer established by the first information is used to transmit.

[0091] In the fourth scenario (where the first information is associated with one or more data transmission task types and the data transmission task types are implemented using the second definition method), the information content included in the first information can assist the terminal device in confirming which type of data corresponding to which functional characteristic the wireless bearer established by the first information is used to transmit. For example, the first information includes wireless bearer identification information and first indication information; or the first information includes wireless bearer identification information, first indication information, and first identification information; or the first information includes wireless bearer identification information, first indication information, first identification information, and third indication information; or the first information includes wireless bearer identification information, first indication information, first identification information, and third indication information. For another example, the first information includes wireless bearer identification information, first indication information, and second indication information; or the first information includes wireless bearer identification information, first indication information, second indication information, and first identification information; or the first information includes wireless bearer identification information, first indication information, second indication information, first identification information, and third indication information; or the first information includes wireless bearer identification information, first indication information, second indication information, first identification information, and third indication information, wherein the first indication information can assist the terminal device in confirming which type of data corresponding to which functional characteristic the wireless bearer established by the first information is used to transmit. For example, the first information includes radio bearer identification information; or the first information includes radio bearer identification information and first identification information; or the first information includes radio bearer identification information and third indication information; or the first information includes radio bearer identification information, first identification information and third indication information, and the position of the parameter carrying the first information and / or the value of the radio bearer identification information can assist the terminal device in confirming which type of data corresponding to which functional characteristic the radio bearer established by the first information is used to transmit.

[0092] In some implementations, as shown in Figure 3, in step 230, the network device sends second information to the terminal device; correspondingly, in step 240, the terminal device receives the second information sent by the network device.

[0093] The second information includes measurement configuration information associated with the data transmission task, and further includes one or more of the following: bearer identification information corresponding to one or more radio bearers associated with the measurement configuration information; and first identification information associated with the measurement configuration information. For example, the second information includes measurement configuration information and one or more radio bearer identification information associated with the measurement configuration information; or, for another example, the second information includes measurement configuration information and first identification information associated with the measurement configuration information.

[0094] The purpose of the second information is to associate measurement configuration information with radio bearers (e.g., signaling radio bearers or data radio bearers). Measurement configuration information is typically associated with specific functional characteristics (e.g., the associated functional characteristics are implicitly determined by the predefined location of the parameters carrying the measurement configuration information in the protocol). In the first, second, and third scenarios described above, because the associated functional characteristics of the radio bearers are unclear, without additional indication, the terminal device cannot effectively confirm the association between the measurement configuration information and the established radio bearers. This is especially true in scenarios where the network device has multiple sets of measurement configuration information configured; the terminal device can hardly effectively confirm the radio bearers associated with each set of measurement configuration information. To avoid inconsistencies in the understanding of data transmission channels between the terminal device and the network device (inconsistencies may lead to data decoding failures at the data receiver), the second information can additionally indicate one or more radio bearer identification information or a first identification information associated with the corresponding measurement configuration information. In this way, with the radio bearer identification information or the first identification information acting as a bridge, the terminal device clearly understands which measurement configuration information is associated with which radio bearers, thereby transmitting the data collected under the corresponding measurement configuration information through the one or more radio bearers associated with that measurement configuration information. Regarding the fourth scenario described above, the functional characteristics associated with the first information are explicit, and the functional characteristics associated with specific measurement configuration information can also be confirmed implicitly. In one implementation, the second information does not need to include radio bearer identification information or the first identification information. The terminal device can still implicitly confirm the radio bearer associated with the measurement configuration information through the functional characteristics associated with the measurement configuration information (using the functional characteristics as a bridge between the two). This implementation works, but when the number and types of measurement configuration information configured by the network device are too large, this many-to-many implicit association method may cause the terminal device to misunderstand the scenario. It is not an absolutely safe implementation method. Therefore, in another implementation method, the second information still includes radio bearer identification information or the first identification information. In this way, regardless of which implementation method the first information adopts, the terminal device can confirm which radio bearers the measurement configuration information is associated with through one or more radio bearer identification information or the first identification information associated with the corresponding measurement configuration information. This implementation method can greatly simplify the implementation method of the terminal device, avoid the introduction of complex implicit association rules, and also avoid the occurrence of terminal device implementation errors that may be caused by implicit association rules.

[0095] In one implementation, the measurement configuration information may include reference signal configurations for collecting measurement data and / or reference signal configurations for collecting model training datasets. For example, the measurement configuration information may include reference signal configurations for collecting measurement data; or, for another example, it may include reference signal configurations for collecting measurement data and reference signal configurations for collecting model training datasets; or, for yet another example, it may include both reference signal configurations for collecting measurement data and reference signal configurations for collecting model training datasets. A detailed description of the reference signal types can be found in the preceding section on measurement-related data, and will not be repeated here.

[0096] In one implementation, measurement configuration information is associated with functional characteristics corresponding to the data. These functional characteristics may include, for example, one or more of the following: CSI compression feedback function; beam management function; positioning function; RRM measurement function; CSI prediction function; RRM event prediction function; sensing function; BFD function; RLF function; channel estimation function; environmental IoT function; and LTM function.

[0097] As an example, the measurement configuration information may include any one of the following: reference signal configuration for collecting measurement data related to CSI feedback function, reference signal configuration for collecting training data related to CSI compressed feedback function, reference signal configuration for collecting measurement data related to beam management function, reference signal configuration for collecting training data related to beam management function, reference signal configuration for collecting measurement data related to positioning function, reference signal configuration for collecting training data related to positioning function, reference signal configuration for collecting measurement data related to RRM measurement function, reference signal configuration for collecting training data related to RRM measurement function, reference signal configuration for collecting training data related to RRM measurement function, reference signal configuration for collecting training data related to CSI prediction function, reference signal configuration for collecting training data related to RRM event prediction function, reference signal configuration for collecting measurement data related to sensing function, reference signal configuration for collecting training data related to sensing function, reference signal configuration for collecting training data related to BFD function, reference signal configuration for collecting training data related to RLF function, reference signal configuration for collecting training data related to channel estimation function, and reference signal configuration for collecting measurement data related to environmental IoT function.

[0098] In one implementation, the second information includes measurement configuration information and radio bearer identification information associated with the measurement configuration information. In this case, the first information is implemented in any of the four implementation methods described above. In this implementation, the radio bearer identification information serves as a bridge, establishing an association between the measurement configuration information and one or more specific radio bearers. Data obtained using the measurement configuration information and through the measurement process of the terminal device can then be transmitted to the network device via the one or more radio bearers associated with the measurement configuration information.

[0099] In another implementation, the second information includes measurement configuration information and a first identification information associated with the measurement configuration information. In this case, the first information is implemented in any of the four scenarios described above where the first information includes the first identification information. In this implementation, the first identification information serves as a bridge, establishing an association between the measurement configuration information and one or more specific radio bearers. Data obtained using the measurement configuration information and through the measurement process of the terminal device can then be transmitted to the network device via the one or more radio bearers associated with the measurement configuration information.

[0100] In this embodiment of the application, the first information and the second information can be carried by the same RRC message (e.g., the first information and the second information are carried in the same reconfiguration message); or, the first information and the second information can be carried by different RRC messages (e.g., the first reconfiguration message is used to configure the measurement configuration information included in the second information, and the second reconfiguration message is used to incrementally configure the first information and the association relationship between the first information and the second information).

[0101] Based on the above description, in this embodiment of the application, the access network is allowed to trigger the establishment of data radio bearer resources, and when configuring the radio bearer, the purpose of the corresponding radio bearer can be flexibly indicated by the first information (i.e., the type of data corresponding to which functional characteristic the established radio bearer is used to transmit), which greatly improves the efficiency of transmitting large-capacity data between the terminal device and the access network device. And / or, the access network is allowed to trigger the establishment of data radio bearer resources, and when configuring the measurement configuration, the second information specifies which radio bearers the measurement configuration information (e.g., measurement configuration related to model training data collection) is associated with, facilitating the transmission of collected measurement data (e.g., transmitting large-capacity model training datasets) through the associated radio bearers.

[0102] The method embodiments of this application have been described in detail above with reference to Figures 1 to 3. The apparatus embodiments of this application will be described in detail below with reference to Figures 4 to 6. It should be understood that the descriptions of the method embodiments correspond to the descriptions of the apparatus embodiments; therefore, any parts not described in detail can be referred to the preceding method embodiments.

[0103] Figure 4 is a schematic diagram of the structure of a terminal device provided in an embodiment of this application. The terminal device 400 shown in Figure 4 may include a transceiver unit 410. The transceiver unit 410 is used to receive one or more first information sent by a network device. The first information is used to establish one or a group of radio bearers. The first information includes radio bearer identification information of the radio bearer and is associated with a data transmission task type.

[0104] In some implementations, the data transmission task type associated with the first information is determined based on the position of the parameter carrying the first information.

[0105] In some implementations, the data transmission task type associated with the first information is determined based on the value of the radio bearer identifier information included in the first information.

[0106] In some implementations, the first information further includes first indication information, which is used to indicate the data transmission task type associated with the first information.

[0107] In some implementations, the data transmission task type includes: model training dataset transmission task; and / or, measurement-related data transmission task.

[0108] In some implementations, the data transmission task type includes one or more of the following: model transmission task; model parameter transmission task; terminal device capability information transmission task.

[0109] In some implementations, the data transmission task type is defined according to the data type being transmitted, or according to the data type being transmitted and the functional characteristics associated with that data type.

[0110] In some implementations, the data transmission task type is defined according to the data type being transmitted, and the first information further includes second indication information, which is used to indicate the functional characteristics corresponding to the data transmission task type associated with the first information.

[0111] In some implementations, the first information further includes first identification information, which is used to indicate the correlation between multiple radio bearers established based on different first information, or the first identification information is used to indicate group identification information of a group of radio bearers established based on one first information.

[0112] In some implementations, the first information further includes third indication information, which is used to indicate the QoS requirements that the data transmitted on the radio bearer established based on the first information needs to meet.

[0113] In some implementations, the transceiver unit 410 is further configured to: receive second information sent by the network device, the second information including measurement configuration information associated with the data transmission task, the second information further including: radio bearer identification information corresponding to one or more radio bearers associated with the measurement configuration information; or, first identification information associated with the measurement configuration information.

[0114] In some implementations, the measurement configuration information includes: a reference signal configuration for collecting measurement data; and / or, a reference signal configuration for collecting model training datasets.

[0115] In some implementations, the measurement configuration information is associated with functional characteristics.

[0116] In some implementations, the functional characteristics include one or more of the following: CSI compression feedback function; beam management function; positioning function; RRM measurement function; CSI prediction function; RRM event prediction function; sensing function; BFD function; RLF function; channel estimation function; environmental IoT function; LTM function.
