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.

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.

[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 network device (e.g., a gNB), or may be an entity of a UE or a core network (e.g., an LMF or an AMF), or may 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 UE, or may be an entity of a gNB or a core network (e.g., an LMF or an AMF), or may be a partial function or entity of any of the above devices. In addition, FIG1 illustrates positioning as an example, but the present application is not limited thereto. 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 sending method, which is described from the perspective of a model sending device. The model sending device can be a network device (such as a base station), a terminal device (such as a target device, a PRU, or other terminal), 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 network device sends configuration information to a terminal device, where the configuration information is used to configure or instruct the terminal device to receive some data blocks of a model.

[0066] 202. The network device sends a partial data block of the model to the terminal device.

[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] Therefore, the network device divides the model and sends configuration information and partial data blocks of the model; the terminal device receives the partial data blocks of the model according to the configuration information; thereby, air interface transmission of larger models can be achieved, which can meet the requirements of AI / ML model transmission and solve various potential problems caused by the transmission of AI / ML models between entities.

[0069] In the embodiment of the present application, the data transmitting device divides the model into multiple mutually exclusive parts using a certain method (e.g., segmentation), and each partial data block carries a portion of the model content. After receiving these partial data blocks, the data receiving device combines them using a certain method to obtain the model content.

[0070] Without causing confusion, the terms "partial data block" and "split block", "split part", "transmission block", "part of the model", etc. can be interchanged, and the terms "configuration information", "model segmentation information", etc. can be interchanged, but this application is not limited to this.

[0071] In some embodiments, the configuration information includes at least one of the following: identification of the model, identification of partial data blocks of the model, number of partial data blocks of the model, order of partial data blocks of the model, and size of partial data blocks of the model.

[0072] For example, the configuration information may include the number of partial data blocks by enhancing the RRC message DLDedicated MessageSegment in 3GPP protocol TS38.331 to provide the order of the partial data blocks (also referred to as segmented blocks).

[0073] For example, the upper limit of the field segmentNumber-r16 INTEGER (0..4) that defines the maximum number of segmentations in the protocol is 4 (that is, a maximum of 5 segmentation blocks). The embodiment of the present application can directly adjust the upper limit, for example, expressed as segmentNumber-r16 INTEGER (0..63), so as to give a suitable number of segmentation blocks.

[0074] For another example, the upper limit can be adjusted to a configurable parameter, such as segmentNumber-r16 INTEGER (0..maxNumSeg). This parameter is defined as an optional configuration (e.g., with several options) and can also be determined through signaling interaction. This configuration parameter can be notified to the terminal device through an RRC message before transmission.

[0075] In some embodiments, the configuration information includes a multi-dimensional sequence; the multi-dimensional sequence indicates a hierarchical structure between partial data blocks of the model.

[0076] For example, a two-dimensional segmentation sequence definition can be used to represent the hierarchical structure of an AI / ML model. For example, multiple segmentation sequences can be defined: segmentation sequence 1, segmentation sequence 2, and so on. For example, two segmentation sequences can be in a containment relationship or a parallel relationship.

[0077] For example, if two segmentation sequences are in a parallel relationship, segmentation sequence 1 can indicate the corresponding parameters of the model at different network layers, and segmentation sequence 2 can indicate all the corresponding parameters of the model at different neurons. For another example, if the two segmentation sequences are in an inclusive relationship, segmentation sequence 1 can indicate a larger segmentation order, while segmentation sequence 2 can indicate the segmentation order within segmentation sequence 1, and so on. The DLDedicatedMessageSegment message can be enhanced to be applicable to multi-dimensional sequences.

[0078] In some embodiments, the network device sends a final identifier of the multi-dimensional sequence to the terminal device, where the final identifier is used to indicate the last partial data block in a certain dimensional sequence, for the terminal device to perform model reconstruction.

[0079] For example, when a multidimensional sequence is used for indication, a final flag corresponding to the multidimensional sequence can be given. The final flag indicates that the currently transmitted segment block is at the end of the transmission sequence. After receiving the flag, the terminal device can perform operations such as partial model reconstruction.

[0080] In some embodiments, the network device may also append additional information of the current transmission segment block in the DLDedicatedMessageSegment enhanced information, such as a model identifier (MODEL ID), a transmission block size (SIZE), and the like.

[0081] The above is a schematic illustration of the configuration information, and the present application is not limited thereto. For example, the configuration information may also include model segmentation information, which may include at least one of the following: an identifier of a data segment block or data segment portion, a model segmentation identifier, a model segmentation timestamp, a model segmentation rule, a model layer identifier, an input data source identifier, a model segmentation size, model segmentation statistics, and data statistics information. The present application is not limited thereto, and the configuration information may include any combination of the above information, or may include other information.

[0082] In some embodiments, the data statistical information includes at least one of the following: a maximum value of a data segment or a data segment, a minimum value of a data segment or a data segment, an average value of a data segment or a data segment, a variance of a data segment or a data segment, a size of each data segment or a data segment, and a total size of the data segment or a data segment. The present application is not limited thereto, and may also include any combination of the above information, or include other information.

[0083] In some embodiments, the model segmentation statistics include at least one of the following: weight mean, weight variance, partial model content mean, partial model content variance. The present application is not limited thereto, and may also be any combination of the above information, or include other information.

[0084] FIG3 is an example diagram of a model transmission method according to an embodiment of the present application. For example, the model transmission device is a gNB and the model receiving device is a UE.

[0085] As shown in 301 of Figure 3, the model sending device can segment the model to generate configuration information (for example, including model segmentation information) and partial data blocks of the model (at least partial model). As shown in 302 of Figure 3, the model sending device can transmit the model segmentation information to the model receiving device through RRC messages, MAC CE, DCI / UCI, etc. As shown in 303 of Figure 3, the model sending device can send at least part of the model to the model receiving device. As shown in 304 of Figure 3, the model receiving device reorganizes at least part of the received model according to the model segmentation information. Thus, for example, at least part of the key model that has been segmented in the current application can be transmitted, so that in some cases, SRB can be used to complete efficient transmission of the model.

[0086] 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.

[0087] For example, 302 and 303 may be combined (e.g., using the same message or signaling), i.e., the model segmentation information is transmitted while at least a portion of the model is being transmitted. For another example, the model segmentation information is transmitted after at least a portion of the model. For another example, the model segmentation information is transmitted as part of at least a portion of the model.

[0088] In some embodiments, the partial data blocks of the model (at least a partial model) are 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 303 is sent via an SRB, or via a DRB, or via both an SRB and a DRB.

[0089] In some embodiments, the configuration information (model segmentation 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). The present application is not limited thereto, and depending on the sender and receiver, the configuration information (model segmentation information) may also be sent via the following signaling: uplink control information (UCI), LPP (LTE Positioning Protocol) signaling, or NRPPa (NR Positioning Protocol A) signaling. For example, the model segmentation information in 302 is sent via DCI.

[0090] For example, the model sending device transmits data segmentation rule information (model segmentation information) to the model receiving device. This rule information is mainly used to assist the model receiving device in correctly reassembling the segmented model data or detecting errors. The model segmentation information is further described below.

[0091] For example, the model sending device sends the identification information (ID) of each model segmentation block to the model receiving device. The model segmentation block (segmentation chuck) or model segmentation part (segmentation part) identification can be represented separately by IE, as shown in Table 1:

[0092] Table 1

[0093] In Table 1, the ModelSegmentID of the IE indicates the identifier of the segmentation block or segmentation part. The present application is not limited thereto. For example, the identifier of the model segmentation block (segmentation chuck) or model segmentation part (segmentation part) can be combined with other information through the IE, as shown in Table 2:

[0094] Table 2

[0095] For another example, implicit identification can be used to transmit model segmentation information. The model sending device sends implicit identification information of the model segmentation block (part) to the model receiving device. The implicit identification information is sent together with the implicit rule, for example, by attaching time stamp information in IE, as shown in Table 3:

[0096] Table 3

[0097] We can also use IE to give the neural network hierarchy rules, as shown in Table 4:

[0098] Table 4

[0099] For another example, data statistics of the segmented blocks can be transmitted. The model sending device sends data statistics of the model segmented blocks (parts) to the model receiving device, for example, by appending the data size of each segmented part and / or the total data size of all segmented parts and / or the weighted statistical distribution of the segmented parts (e.g., mean, variance, etc.) in the IE, as shown in Table 5:

[0100] Table 5

[0101] The above is an exemplary description of the configuration information (model segmentation information), but the present application is not limited thereto.

[0102] In some embodiments, the model sending device receives feedback information from the model receiving device.

[0103] FIG4 is another example diagram of the model sending method according to an embodiment of the present application. For example, the model sending device is a gNB and the model receiving device is a UE.

[0104] As shown in 401 of FIG. 4 , the model transmitting device may segment the model to generate model segmentation information and at least a portion of the model. As shown in 402 of FIG. 4 , the model transmitting device may transmit the model segmentation information to the model receiving device via an RRC message, MAC CE, DCI / UCI, etc. As shown in 403 of FIG. 4 , the model transmitting device may transmit at least a portion of the model to the model receiving device.

[0105] As shown in 404 of FIG. 4 , the model receiving device may optionally send feedback information to the model sending device. For example, this may include feedback that data statistics were not received and a request for retransmission, feedback that a data block (data portion) was not received, or feedback that all information has been received. As shown in 405 of FIG. 4 , the model receiving device reassembles at least a portion of the received model based on the model segmentation information. This allows, for example, the transmission of a segmented portion of a key model for the current application, 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] For example, 402 and 403 can be combined together (e.g., using the same message or signaling), that is, the model segmentation information is transmitted at the same time as the at least partial model is sent. For another example, the model segmentation information is sent after the at least partial model. For another example, the model segmentation information is sent as part of the at least partial model. For another example, multiple information exchanges can be performed before 405 until all the information required for model reconstruction has been obtained by the model receiving device. For another example, if the feedback transmission in 404 fails, the model reconstruction in 405 can be canceled.

[0108] In some embodiments, the model sending device receives auxiliary information from the model receiving device for assisting in segmenting the model into partial data blocks.

[0109] For example, the auxiliary information includes at least one of the following: performance quality requirements, performance evaluation information, and priority information. The present application is not limited thereto, and may also be any combination of the above information, or include other information.

[0110] In some embodiments, the auxiliary 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).

[0111] For example, before the model sending device segments the model, the sender and receiver may perform some signaling interaction to provide auxiliary information for model segmentation, so that the model sending device can better segment the model. For example, the sender may request the receiver to send auxiliary information, or the receiver may proactively send auxiliary information when the model transmission is initiated. The transmission of auxiliary information can use RRC messages, MAC CE, UCI, etc.

[0112] FIG5 is another example diagram of the model sending method according to an embodiment of the present application. For example, the model sending device is a gNB and the model receiving device is a UE.

[0113] As shown in 501 of FIG. 5 , the model receiving device may send auxiliary information to the model sending device. The auxiliary information may be sent based on a request from the model sending device or may be sent proactively by the model receiving device. As shown in 502 of FIG. 5 , the model sending device may segment the model based on the auxiliary information to generate model segmentation information and at least a partial model. As shown in 503 of FIG. 5 , the model sending device may transmit the model segmentation information to the model receiving device via an RRC message, MAC CE, DCI / UCI, or the like. As shown in 504 of FIG. 5 , the model sending device may send at least a partial model to the model receiving device.

[0114] As shown in 505 of FIG. 5 , the model receiving device may optionally send feedback information to the model sending device. For example, this may include feedback that data statistics were not received and a request for retransmission, feedback that a data block (data portion) was not received, or feedback that all information has been received. As shown in 506 of FIG. 5 , the model receiving device reassembles at least a portion of the received model based on the model segmentation information. This allows, for example, the transmission of a segmented portion of a key model for the current application, enabling efficient model transmission using SRB in some cases.

[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, before 501, the model sending device may send a request message to the model receiving device to request the model receiving device to send auxiliary information. For another example, 503 and 504 can be combined together (for example, using the same message or signaling), that is, the model segmentation information is transmitted while sending at least part of the model. For another example, the model segmentation information is sent after at least part of the model. For another example, the model segmentation information is sent as part of at least part of the model. For another example, multiple information interactions can be performed before 506 until the information required for model reorganization has been obtained by the model receiving device. For another example, in the event that the feedback transmission fails in 505, the model reorganization in 506 can be canceled.

[0117] The above is an exemplary description of information interaction, and the following is an exemplary description of auxiliary information.

[0118] For example, the model receiving device sends service quality requirements or QoS information to the model sending device as needed, wherein the service quality requirements can be specifically specified in combination with specific application instances. Table 6 illustrates this using an example of a wireless positioning application.

[0119] Table 6

[0120] In some embodiments, the network device receives terminal capability information and / or model identification information sent by the terminal device, and the terminal capability information and / or the model identification information are used by the network device to generate the configuration information.

[0121] In some embodiments, the network device calculates the maximum number of partial data blocks of the model based on the terminal capability information and / or model identification information; and includes the maximum number in the configuration information and sends it to the terminal device.

[0122] For example, the gNB can query the current UE's storage capacity and other related information through methods such as UE Capability. After the UE reports its capabilities as needed, the gNB can calculate maxNumSeg through its own algorithm and send it to the UE through an RRC message.

[0123] In some embodiments, the network device receives indication information of retransmission, suspension of transmission or termination of transmission sent by the terminal device.

[0124] For example, after receiving the configuration information and some data blocks from the network device, the terminal device can discard some of the data blocks as instructed by the configuration information, or reassemble some of the data blocks before starting AI / ML reasoning. This AI / ML reasoning does not need to wait until all data blocks are received. The terminal device can also request the network device to retransmit some of the data blocks or stop transmitting the remaining blocks through RRC messages based on the reasoning results. The network device retransmits or terminates the transmission after receiving the message.
