Description

Model sending and receiving method and device Technical Field

[0001] The present application relates to the field of communication technology. Background Art

[0002] In recent years, artificial intelligence (AI / ML), exemplified by deep learning, has rapidly developed and, due to its powerful ability to solve nonlinear problems, has been applied across a wide range of research and commercial fields. Similarly, AI has significantly improved the performance of various wireless communication applications compared to traditional methods. During the 3GPP standards discussions for Release 18, three AI applications in wireless communication were initially identified: channel state information (CSI) feedback, beam management, and wireless positioning. Future discussions do not rule out the introduction of more wireless communication applications that utilize AI technologies.

[0003] While the application of AI in wireless communications can bring many benefits, such as reducing beam management resource overhead and improving wireless positioning accuracy, it also introduces some unique challenges specific to AI technology. One of these challenges is the transmission of AI models between wireless communication entities.

[0004] Generally speaking, the current main artificial intelligence technology is deep learning. In deep learning, a model file (referred to as model) is obtained after data training. The model file stores the neural network structure of the deep learning model and the weight parameters between each node in the network.

[0005] The application of this neural network model in wireless communications generally faces the following problems:

[0006] For example, since neural networks are "deep", in order to achieve better nonlinear fitting capabilities, the number of model layers and the number of neurons (nodes) required in each layer will not be too small. The direct consequence of this is that the model requires a large amount of storage space, with a typical size of between 10-100MB.

[0007] For example, due to the particularity of wireless communication networks, in some necessary cases, the model needs to be transmitted between various entities such as user equipment (UE), base station (gNB), positioning management function (LMF, Location Management Function) entity, access and mobility management function (AMF, Access and mobility Management Function) entity, etc., and the transmission must ensure certain quality requirements, such as integrity and timeliness. If these requirements are not met, the performance of the artificial intelligence model in a certain application will be greatly reduced, and it may even fail to meet the minimum requirements of a certain application, and the use of the artificial intelligence algorithm will have to be abandoned.

[0008] It should be noted that the above introduction to the technical background is merely intended to provide a clear and complete description of the technical solutions of this application and facilitate understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this application, it should not be assumed that the above technical solutions are well known to those skilled in the art.

[0047] In the embodiments of the present application, the term "network device" refers to, for example, a device in a communication system that connects a terminal device to the communication network and provides services to the terminal device. Network devices may include, but are not limited to, the following devices: base station (BS), access point (AP), transmission reception point (TRP), broadcast transmitter, mobile management entity (MME), gateway, server, radio network controller (RNC), base station controller (BSC), etc.

[0048] Base stations may include, but are not limited to, NodeB (NB), evolved NodeB (eNodeB or eNB), 5G base stations (gNB), IAB hosts, and the like.

[0052] The following describes the scenarios of the embodiments of the present application through examples, but the present application is not limited thereto.

[0053] FIG1 is a schematic diagram of a communication system according to an embodiment of the present application, schematically illustrating a situation using a terminal device and a network device as an example. As shown in FIG1 , a communication system 100 may include a network device 101, a terminal device 102, and a positioning server 103. For simplicity, FIG1 illustrates only one terminal device and one network device as an example, but the embodiments of the present application are not limited thereto.

[0054] In the embodiment of the present application, existing services or future services can be transmitted between the network device 101 and the terminal device 102. For example, these services may include, but are not limited to, enhanced mobile broadband (eMBB), massive machine type communication (mMTC), and ultra-reliable and low-latency communication (URLLC), etc.

[0055] It is worth noting that Figure 1 shows that the terminal device 102 is within the coverage of the network device 101, but the present application is not limited to this. The terminal device 102 may not be within the coverage of the network device 101. In addition, Figure 1 uses the example of a separate deployment of the positioning server 103 as an example. The AI / ML model can be run in the positioning server 103 to obtain the positioning result; however, the present application is not limited to this. The positioning server 103 can be deployed in the core network, in the network device 102 (such as a base station), or in the terminal device 103; the embodiments of the present application are not limited to these situations.

[0056] In the embodiments of this application, the terminal device to be located may be referred to as the target device, and the function of the positioning server may be referred to as the Location Management Function (LMF). The LMF may be a network entity that locates and manages the terminal, and the location server with the location management function may be referred to as the LMF. To avoid confusion, the terms "LMF" and "location server" are interchangeable. For details on these concepts and positioning, please refer to the relevant art.

[0057] In an embodiment of the present application, the model sending device (also referred to as a model sending module or a model sending entity) is a terminal device, but it can also be an entity of a gNB or a core network (such as an LMF or an AMF), or it can also be a partial function or entity of any of the above devices. The model receiving device (also referred to as a model receiving module or a model receiving entity) is a network device, but it can also be an entity of a UE or a core network (such as an LMF or an AMF), or it can also be a partial function or entity of any of the above devices. In addition, Figure 1 is illustrated using positioning as an example, but the present application is not limited to this. The model transmission solution of the present application can be applied to any scenario using AI / ML models.

[0058] The current 3GPP protocol supports radio interface transmissions over the control plane and user plane, with signaling radio bearers (SRBs) and data radio bearers (DRBs) corresponding to these two types of transmission. Both mechanisms have inherent drawbacks when implementing AI / ML model transmission:

[0059] If SRB is configured for control plane transmission, although SRB transmitted via RRC messages has a higher transmission priority, the amount of data that can be carried by a single RRC message is relatively limited. When the model is large, using only SRB requires many RRC messages to transmit, which may not be possible in terms of efficiency and latency.

[0060] If DRB is configured for user-plane transmission, although it can carry a large amount of data, the transmission priority of DRB is low and the transmission content is invisible, there are also problems in quality and delay control.

[0061] Therefore, current mechanisms cannot address the various potential problems caused by transmitting AI / ML models between entities.

[0062] Embodiments of the first aspect

[0063] The present application provides a model transmission method, which is described from the perspective of a model transmission device. The model transmission device is a terminal device (e.g., a target device, a PRU, or other terminal) or a module or functional entity in the terminal device, but the present application is not limited thereto. For example, it can also be a network device (e.g., a base station) or a location server with LMF functionality.

[0064] FIG2 is a schematic diagram of a model sending method according to an embodiment of the present application. As shown in FIG2 , the method includes:

[0065] 201. A terminal device receives configuration information from a network device, where the configuration information is used to configure or instruct the terminal device to send at least a portion of a model stored in the terminal device.

[0066] 202. The terminal device sends at least a portion of the model to the network device according to the configuration information.

[0067] It is worth noting that FIG2 above is merely a schematic illustration of an embodiment of the present application, and the present application is not limited thereto. For example, the execution order of the various operations may be appropriately adjusted, and other operations may be added or some operations may be reduced. Those skilled in the art may make appropriate modifications based on the above description, and are not limited to the description of FIG2 above.

[0068] As a result, network devices and terminal devices interact with each other and transmit at least part of the model on demand based on the interaction information, thereby realizing air interface transmission of larger models, meeting the requirements of AI / ML model transmission, and solving various potential problems caused by the transmission of AI / ML models between entities.

[0069] In some embodiments, the configuration information includes at least model information and / or transmission information.

[0070] For example, the model information includes at least one of the following: model structure, model type, model layer information, model parameter information, model weight type, model weight accuracy, and model transmission type; the present application is not limited to this, and can also be any combination of the above information, or include other information.

[0071] For example, the configuration information can specify the type or content of the model transmission. Various contents can be predefined first, and then the configuration information can include predefined content 1, predefined content 2, ..., predefined content N, etc. The predefined content can be agreed upon between the network device and the terminal device, for example, through UE capability reporting or model identification, as described later.

[0072] In some embodiments, the transmission information may include: transmission configuration information and / or transmission format information.

[0073] For example, the transmission configuration information includes at least one of the following: transmission period, maximum available transmission resources, maximum transmission delay, and transmission silent window; the present application is not limited thereto, and may also be any combination of the above information, or include other information.

[0074] For example, the transmission format information can indicate a common storage format for AI / ML models (e.g., ONNX, Pytorch, etc.); it can also indicate a currently defined or future data transmission format in a wireless communication network; or it can indicate a compilable non-universal storage format. The receiver can use this transmission format information to inform the sender that the file or data carrying the model is transmitted in an agreed format.

[0075] For another example, a network device can instruct a terminal device, through configuration information, to transmit only the portion of content that has changed compared to the previous transmission. The definition of "change" can be provided by the network device in different forms via RRC messages. For example, the network device can configure an upper limit on the amount of content that can be transmitted, and the terminal device can independently determine which content to transmit within the upper limit. For another example, the network device can provide detailed definitions of the content upper limit, such as the upper limit on the number of parameters and the upper limit on the total transmission overhead.

[0076] For another example, the network device can also specify the threshold of "change" through configuration information. For example, the network device can also provide the terminal device with other relevant information about the relative value model parameters, such as using configuration parameters to specify a certain threshold of the relative change value, and specifying that the terminal device will only transmit the parameter when the relative change value of the parameter meets the condition; for another example, the network device can also specify the number of model parameters that need to be transmitted to the terminal device, and send a response parameter selection mechanism, such as agreeing that only the 500 parameters with the largest relative change values ​​need to be transmitted. In the above example, the "relative change value" is, for example, the difference between the parameter value of the model to be transmitted this time and the parameter value of the model to be transmitted last time. The difference may be the absolute value (non-negative) or the relative value of the difference.

[0077] In some embodiments, the terminal device sends terminal capability information and / or model identification information to the network device, and the terminal capability information and / or the model identification information are used by the network device to generate the configuration information.

[0078] For example, before the network device sends the configuration information, the terminal device may use the UE capability IE or the model identification IE to interact with the network device, so that the network device can send the configuration information to the terminal device in a targeted manner.

[0079] In some embodiments, the network device sends a request to the terminal device for terminal capabilities and / or model identification; and the terminal device sends the terminal capability information and / or the model identification information to the network device in response to the request. The terminal capability information and / or the model identification information includes capability information for transmitting a portion of the model content.

[0080] For example, the network device may ask the terminal device whether it has the capability to transmit the model, whether it has the capability to transmit only part of the model (such as only model parameters, only model structure, etc.), whether it has the capability to obtain and transmit the relative change value of the model parameters, etc. The terminal device reports the above capabilities as needed through the UE Capability method according to the requirements of the network device.

[0081] For another example, the terminal device can report the model identification number (or model identification sequence, model identification, model ID) and / or other relevant information corresponding to the above model to the network device through the model identification process. The model identification number or other relevant information contains various capability information corresponding to the content of the transmission model.

[0082] Figure 3 illustrates an example of a model transmission method according to an embodiment of the present application. For example, the model transmitting device is a UE, and the model receiving device is a gNB. Prior to model transmission, the transmitting and receiving devices may communicate basic model transmission requirements through signaling.

[0083] As shown in 301 of FIG. 3 , the model receiving device may proactively transmit configuration information to the model transmitting device via RRC messages, MAC CE, DCI / UCI, etc. As shown in 302 of FIG. 3 , the model transmitting device transmits at least a portion of the model based on this configuration information. This allows, for example, only the key portion of the current application model to be transmitted as needed, enabling efficient model transmission using SRB in some cases.

[0084] It is worth noting that FIG3 above is merely a schematic illustration of an embodiment of the present application, and the present application is not limited thereto. For example, the execution order of the various operations may be appropriately adjusted, and other operations may be added or some operations may be reduced. Those skilled in the art may make appropriate modifications based on the above description, and are not limited to the description of FIG3 above.

[0085] In some embodiments, at least a portion of the model is sent via a signaling radio bearer (SRB) and / or a data radio bearer (DRB). For example, at least a portion of the model shown in 302 is sent via an SRB, or via a DRB, or via both an SRB and a DRB.

[0086] In some embodiments, the configuration information is sent via at least one of the following: a radio resource control (RRC) message, a medium access control (MAC) control element (CE), or downlink control information (DCI). For example, the model transmission information in 301 is sent via DCI. In addition, depending on the model sending device and the model receiving device, the configuration information may also be uplink control information (UCI), LPP (LTE Positioning Protocol) signaling, or NRPPa (NR Positioning Protocol A) signaling.

[0087] The following further describes the configuration information.

[0088] For example, if the gNB chooses to send model structure information to the UE, it can use an IE to select a preset model structure information; for example, this information can be in the form of a string or data bits. For example, the enumerated type ModeType can be used, including information indicating the model structure, such as "CNN," "DNN," "RNN," and "Transformer." Another example is the enumerated type ModelType, including {0, 1, 2, .... 15}, where 0-15 represent 16 preset network structures, such as CNN, Transformer, etc., or other types can be specified.

[0089] For another example, if the gNB chooses to send model structure information to the UE, it can use IE to specify the neural network model structure information. This method can specify more than the preset model structure. For example, the IE can be as shown in Table 1:

[0090] Table 1

[0091] The above is an exemplary description of the model structure information. The following is an exemplary description of the model parameter information.

[0092] For example, if the gNB chooses to send model parameter information to the UE, it can use IE to select the model parameters. For example, the expression "absolute" or "relative" can be used to indicate whether the model parameter is a relative change value or an absolute value.

[0093] For example, if the gNB chooses to send model parameter information to the UE, it can use an IE to specify the model parameter accuracy. For example, the enumeration type ModelWeightsAccuracy can be used, including {0,1,2,….15}, where 0-15 corresponds to the number of digits after the decimal point of the weight parameter, indicating the accuracy of the model parameter.

[0094] The above is an exemplary description of the model parameter information. The following is an exemplary description of the transmission type information.

[0095] For example, if the gNB chooses to send model transmission type information to the UE, an IE may be used to specify the model transmission type. For example, an enumerated type IE may be used to define the model transmission type, such as ModelTransmissionType, which may include information indicating the model transmission type, such as "structure-only," "weights-only," "parameter-only," "partial-parameter," "hybrid," and "full." These information may correspond to transmission of only the model structure, only the model weights, only the model parameters, partial model parameters, hybrid transmission, and full transmission, respectively.

[0096] The above is an exemplary description of the transmission type information. The following is an exemplary description of the transmission configuration information.

[0097] For example, if the gNB chooses to send model transmission configuration information to the UE, the model transmission configuration may be specified using IEs, such as multiple parallel IEs or a single IE, as shown in Table 2.

[0098] Table 2

[0099] In Table 2, for example, Period specifies the transmission period, MaxLatency specifies the maximum delay of model reception, both of which can be identified by time units such as ms, and SilenceWindow specifies a period during which model transmission cannot be received, which can be defined by concepts such as SFN.

[0100] The above is an exemplary description of the configuration information, and the present application is not limited thereto.

[0101] In some embodiments, the terminal device receives auxiliary information from the network device; the auxiliary information includes expected performance and / or expected maximum reception time.

[0102] For example, the auxiliary information includes relevant information of the application that needs to use the model to be transmitted, such as the expected performance gain of the application, the maximum time limit expected to be received by the application, etc. The auxiliary information can be sent to the terminal device together with the configuration information, or can be sent separately using different RRC signaling, or the auxiliary information can also be used as part of the configuration information.

[0103] In some embodiments, the model sending device sends request information for requesting configuration information to the model receiving device.

[0104] Figure 4 is another example diagram of a model transmission method according to an embodiment of the present application. For example, the model transmitting device is a UE, and the model receiving device is a gNB. Before model transmission, the transmitting and receiving devices can communicate basic model transmission requirements through signaling.

[0105] As shown in 401 of Figure 4 , the UE can send a request message to the gNB to request the gNB to feedback configuration information. As shown in 402 of Figure 4 , the model receiving device can feed the configuration information back to the model transmitting device as needed, for example, via RRC messages, MAC CE, DCI / UCI, etc. As shown in 403 of Figure 4 , the model transmitting device transmits at least a portion of the model based on this information. This allows, for example, only the key portion of the current application model to be transmitted as needed, enabling efficient model transmission using SRB in some cases.

[0106] It is worth noting that FIG4 above is merely a schematic illustration of an embodiment of the present application, and the present application is not limited thereto. For example, the execution order of the various operations may be appropriately adjusted, and other operations may be added or some operations may be reduced. Those skilled in the art may make appropriate modifications based on the above description, and are not limited to the description of FIG4 above.

[0107] In some embodiments, the request information includes at least one of the following: model content information, model transmission configuration information, and model type information; the present application is not limited thereto, and may also be any combination of the above information, or include other information.

[0108] For example, the model content information includes at least one of the following: model structure information, neural network layer information, weight information, partial model content information, weight location information, partial model content location information, model storage related information, and content information carrying model data.

[0109] In some embodiments, the request information is sent via at least one of the following: a radio resource control (RRC) message, a medium access control (MAC) control element (CE), or uplink control information (UCI). The present application is not limited thereto. For example, depending on the sender and receiver, the request information may also be downlink control information (DCI), LPP signaling, or NRPPa signaling.

[0110] In some embodiments, the model transmitting device may further transmit designated information for generating or reorganizing the model to the model receiving device.

[0111] For example, after completing preliminary information collection, the model sending device needs to send the model file or data to the model receiving device. Furthermore, it needs to send information related to the model data (specific information) as needed so that the model receiving device can reassemble the received information into a complete model file. The specific information can be sent together with the model or separately.

[0112] Figure 5 is another example diagram of a model transmission method according to an embodiment of the present application. For example, the model transmitting device is a UE, and the model receiving device is a gNB. Before model transmission, the transmitting and receiving devices can communicate basic model transmission requirements through signaling.

[0113] As shown in 501 of Figure 5 , the UE can send a request message to the gNB to request the gNB to feedback configuration information. As shown in 502 of Figure 5 , the model receiving device can feed the configuration information back to the model transmitting device as needed, for example, via RRC messages, MAC CE, DCI / UCI, etc. As shown in 503 of Figure 5 , the model transmitting device transmits at least a portion of the model based on this information. This allows, for example, only the key portion of the current application model to be transmitted as needed, enabling efficient model transmission using SRB in some cases.

[0114] As shown in 504 in Figure 5, the model sending device may also send designated information to the model receiving device. The model receiving device may reorganize at least part of the received model file according to the designated information to obtain a complete model.

[0115] It is worth noting that FIG5 above is merely a schematic illustration of an embodiment of the present application, and the present application is not limited thereto. For example, the execution order of the various operations may be appropriately adjusted, and other operations may be added or some operations may be reduced. Those skilled in the art may make appropriate modifications based on the above description, and are not limited to the description of FIG5 above.

[0116] For example, step 501 in Figure 5 can be omitted, and the gNB can proactively send configuration information to the UE. For another example, steps 503 and 504 can be combined, with the designated information transmitted simultaneously with at least a portion of the model. For another example, the designated information can be sent before at least a portion of the model. For another example, the designated information can be sent as part of at least a portion of the model.

[0117] In some embodiments, the specified information includes at least one of the following: model identification information, content description information, data statistics information, model content information. The model content information may include, for example, weight initialization information, partial model content initialization information, and partial weight information.

[0118] For example, the model sending device may transmit information related to model weight initialization to the model receiving device. This information may be transmitted using IE, as shown in Table 3:

[0119] Table 3

[0120] In some embodiments, the partial weight information includes: layer identifier, inter-layer position identifier, intra-layer position identifier, and weight difference corresponding to the position; the partial model content information includes: content identifier, content position identifier, and weight difference corresponding to the position.

[0121] For example, the model sending device transmits information about the transmission position and relative difference of some models to the model receiving device, thereby avoiding the simultaneous transmission of all model weights, thereby reducing transmission resource consumption. This information can be transmitted using IE, as shown in Table 4:

[0122] Table 4

[0123] Table 4 shows the inter-layer and intra-layer positions of the weights that need to be updated, and the weight differences that need to be transmitted.

[0124] Tables 1 to 4 above only illustrate some examples of interaction information of the embodiments of the present application. The present application is not limited thereto. For example, these contents can reuse existing IEs or use new IEs; or other information transmission methods can be used.

[0125] In some embodiments, the network device may also send indication information for retransmission, suspension, or termination of transmission.

[0126] For example, after receiving at least a portion of the model sent by the terminal device, the network device can also configure or instruct the terminal device through an RRC message to allow the terminal device to perform operations such as supplementary transmission or resending of the transmitted content. In addition, after receiving partial transmission content, the network device can also suspend or prematurely terminate the model transmission through an RRC message or DCI. The above-mentioned "partial transmission" is, for example, the behavior of the terminal device selecting a portion of the corresponding content of the model to transmit to the network device at the request of the network device.
