[0059] The data transmission method, device, and storage medium provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0060] The term "and / or" in this document is merely a description of the association relationship between associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone.

[0061] The terms "first" and "second" in the specification and drawings of the present application are used to distinguish different objects or different processes for the same object, rather than to describe the specific order of the objects.

[0062] In addition, the terms "including" and "having" and any variations thereof mentioned in the description of the present application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes other unlisted steps or units, or optionally further includes other steps or units inherent to these processes, methods, products, or devices.

[0063] It should be noted that in the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations, or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0064] As an important technology in communication networks, communication-sensing integration technology can enable two independent functions, namely, communication function and sensing function, to coexist in the same system through means such as signal joint design and / or hardware sharing. In this way, while ensuring high-speed communication, it is possible to use the communication system and the reference signals of the communication system to monitor and track sensing targets (e.g., unknown objects and known objects). Therefore, communication-sensing integration technology can be a candidate technology for the sixth generation of mobile communication technology (6th generation mobile networks, 6G).

[0065] Figure 1It is an application scenario diagram for integrated communication and sensing. In this application scenario, the transmission modes of communication and sensing include the network device sensing mode and the terminal device sensing mode. For different transmission modes, the sending nodes and receiving nodes of the sensing signals are also different. For example, in the network device sensing mode, the first network device can send multiple sensing signals, which are scattered by the environment or the sensing target and then received by the first network device as the scattered multiple sensing signals (i.e., echo signals). For another example, in the network device sensing mode, the first network device can send multiple sensing signals, which are scattered by the environment or the sensing target and then received by the first network device and the second network device as the scattered multiple echo signals. For another example, in the network device sensing mode, the terminal device can send multiple sensing signals, which are scattered by the environment or the sensing target and then received by the network device as the scattered multiple echo signals. For another example, in the terminal device sensing mode, the network device can send multiple sensing signals, which are scattered by the environment or the sensing target and then received by the terminal device as the scattered multiple echo signals. For another example, in the terminal device sensing mode, the first terminal device can send multiple sensing signals, which are scattered by the environment or the sensing target and then received by the first terminal device and the second terminal device as the scattered multiple echo signals. For another example, in the terminal device sensing mode, the first terminal device can send multiple sensing signals, which are scattered by the environment or the sensing target and then received by the first terminal device as the scattered multiple echo signals.

[0066] In the communication and sensing system, the network device can first determine the transmission mode of communication and sensing and determine the uplink and downlink signals required for this transmission mode. The network device can configure corresponding sensing signals for the sensing nodes (network devices and / or terminal devices) based on the uplink and downlink signals required for the above transmission mode, and send the sensing signals and receive the echo signals through the sensing nodes, and analyze and process the sensing signals to obtain sensing data.

[0067] Figure 2Shows a schematic diagram of the network architecture of a sensing system. In this schematic diagram, the network element functional entities in the sensing system include: unified data management (UDM), network data analytics function (NWDAF), location management function (LMF), policy control function (PCF), access and mobility management function (AMF), sensing function-consumer (SF-C), sensing function-user (SF-U), network exposure function (NEF), application function (AF), user equipment (UE), radio access network ((R)AN), user plane function (UPF), non-3rd generation partnership project access (N3GPP access), and 3rd generation partnership project-access gateway function (N3-AGF).Among them, the specific functions of the above network element functional entities are as follows: The UDM is responsible for managing the subscription data of users; the NWDAF is responsible for providing network analysis services; the LMF is responsible for performing positioning calculations on terminal devices; the PCF is responsible for user policy control, including session policies, mobility policies, etc.; the AMF is responsible for user access and mobility management; the SF is responsible for providing sensing services, including the selection of sensing nodes, the configuration and coordination of sensing resources, and the processing of sensing data, etc.; the NEF is responsible for opening the capabilities of the 5th generation mobile communication technology (5G) network to external systems; the AF is responsible for communicating with the core network to provide services for users; the UPF is responsible for user plane processing; the N3GPP access is responsible for connecting to the evolved packet core (EPC) in various ways according to the operator's business model and architecture preferences; the N3-AGF is responsible for connecting ordinary telephone users to the softswitch network.

[0072] N3 interface: The N3 interface between the (R)AN and the UPF.

[0073] N5 interface: The N5 interface between the NEF and the PCF.

[0074] N8 interface: The N8 interface between the UDM and the AMF.

[0075] N33 interface: The N33 interface between the NEF and the AF.

[0076] The above briefly introduces the network architecture of the sensing system in this application.

[0077] Communication sensing technology is the integration of communication technology and sensing technology, which can realize the sensing of sensing targets while ensuring high-speed communication. During the communication sensing process, sensing nodes (such as network devices and terminal devices) can send multiple sensing signals. After being scattered by the environment or sensing targets, the sensing nodes receive the multiple scattered sensing signals (i.e., echo signals). The sensing nodes can process the above echo signals to obtain sensing data.

[0078] However, in the process of determining the sensing nodes for sensing the sensing target, if the sensing capabilities and / or data processing capabilities of the determined sensing nodes are poor, it may occur that the sensing nodes cannot process the sensing signals in a timely manner, resulting in a poor sensing effect.

[0079] In view of this, an embodiment of the present application provides a data transmission method. The network device sends third indication information to the sensing network element and receives fourth indication information from the sensing network element. That is to say, the network device can report the sensing capabilities and / or data processing capabilities of the sensing nodes to the sensing network element. In this way, when the sensing network element receives the above-mentioned sensing capabilities and / or data processing capabilities, it can select the sensing nodes for sensing the sensing target and send sensing configuration information to the network device, so that the sensing nodes can sense the sensing target, so as to avoid the situation where the sensing capabilities and / or data processing capabilities of the sensing nodes for sensing the sensing target are poor, so that the sensing nodes can process the sensing signals in a timely manner, and further avoid the problem of poor sensing effect.

The naming of the sensing functional network element in the embodiments of the present application is only exemplary, and the sensing functional network element may have other names, which are not limited herein.

[0087] In another example, the sensing network element 302 may be responsible for sensing services.

[0106] To solve the problems existing in the above-mentioned prior art, the embodiments of the present application propose a data transmission method, which can avoid the problem of poor sensing effect. As Figure 5 shown, the method includes:

[0107] S501. The network device sends third indication information to the sensing network element. Correspondingly, the sensing network element receives the third indication information from the network device.

[0108] Among them, the third indication information is used to indicate the sensing ability and / or data processing ability of the sensing node.

[0109] In a possible embodiment, the sensing node includes a terminal device and / or a network device. The third indication information is specifically used to indicate the sensing ability and / or data processing ability of the terminal device. Or the third indication information is specifically used to indicate the sensing ability / or data processing ability of the network device; or the third indication information is specifically used to indicate the sensing ability and / or data processing ability of the terminal device, and the sensing ability and / data processing ability of the network device.

[0110] As a possible implementation manner, when the sensing node is a terminal device, the implementation process of S501 above may be: the network device can obtain the sensing ability and data processing ability of the terminal device, and send the sensing ability and data processing ability of the terminal device (i.e., the third indication information) to the sensing network element.

[0111] As another possible implementation, when the sensing node is a terminal device, the implementation process of S501 above may also be: The network device obtains the sensing capability and data processing capability of the terminal device, and encapsulates the sensing capability and data processing capability of the terminal device. The network device sends the encapsulated sensing capability and data processing capability of the terminal device (i.e., the third indication information) to the sensing network element. Correspondingly, the sensing network element receives the third indication information from the network device.

[0112] In a possible embodiment, the implementation process for the network device to obtain the sensing capability and data processing capability of the terminal device may be: The terminal device sends the fifth indication information to the network device.

[0113] After the network device receives the sensing capability and / or data processing capability of the terminal device, the network device may request the sensing configuration information of the terminal device from the sensing network element, and send the sixth indication information to the terminal device. The sixth indication information is used to indicate the sensing configuration information of the terminal device configured by the sensing network element.

The sixth indication information is triggered when the sensing capability of the terminal device meets the preset sensing capability.

[0114] As a possible implementation, when the sensing node is a network device, the implementation process of S501 above may be: The network device sends the sensing capability of the network device (i.e., the third indication information) to the sensing network element. Correspondingly, the sensing network element receives the third indication information from the network device.

[0115] In a possible embodiment, the sensing capability includes at least one of the following: the ability to send sensing signals, the ability to receive echo signals, or the sensing type; the sensing signals include at least one of the following: sounding reference signal (SRS), positioning reference signal (PRS), or channel state information-reference signal (CSI-RS).

[0116] It should be noted that the above is only an exemplary description of the sensing capability, and the above sensing capability may also include other capabilities, and the present application does not make any restrictions on this.

[0117] It should be noted that among the sensing capabilities of the network device and the terminal device, the sensing signal sent by the network device can be the same as the echo signal received by the terminal device, and the echo signal received by the network device can be the same as the sensing signal sent by the terminal device. For example, the sensing capabilities of the network device may include the capabilities of the network device to send PRS and CSI-RS and the capabilities of the network device to receive SRS, and the sensing capabilities of the terminal device may include the capabilities of the terminal device to send SRS and the capabilities of the terminal device to receive PRS and CSI-RS. In one example, the data processing capabilities of the terminal device may include the speed of processing the original sensing data and / or the accuracy of processing the original sensing data. The above is only an exemplary description of the data processing capabilities of the terminal device, and the data processing capabilities of the terminal device may also include other capabilities, which are not limited in this application.

[0119]

[0120]

[0121] As an example, when the sensing node is the network device, the third indication information may be the sensing capability reporting information sent by the network device to the sensing network element. As shown in Table 1 below, Table 1 describes at least one of the information element / group name (IE / Group Name), Presence, Range, or IE type and reference.

[0126]

[0127] It should be noted that M is mandatory and can be used to indicate mandatory. True can be used to indicate affirmative, and False can be used to indicate negative. For example, if the network device has the capability to send PRS for sensing, then the Range of PRS is True. If the network device does not have the capability to send PRS for sensing, then the Range of PRS is False.

[0128] S502. The sensing network element sends the fourth indication information to the network device. Correspondingly, the network device receives the fourth indication information from the sensing network element.

[0129] Among them, the fourth indication information is used to indicate the sensing configuration information of the sensing node. The sensing configuration information is used to indicate the resources required for the sensing node to sense the sensing target.

[0130] In a possible embodiment, the fourth indication information is specifically used to indicate the sensing configuration information of the terminal device, or the fourth indication information is specifically used to indicate the sensing configuration information of the network device.

[0131] It should be noted that when the sensing node is a terminal device, the fourth indication information sent by the sensing network element to the network device is used to indicate the sensing configuration information of the terminal device. When the sensing node is a network device, the fourth indication information sent by the sensing network element to the network device is used to indicate the sensing configuration information of the network device.

[0132] In a possible embodiment, the fourth indication information is triggered when the sensing capability of the terminal device meets the preset sensing capability, or when the sensing capability of the network device meets the preset sensing capability.

[0133] In a possible implementation manner, the implementation process of S502 may be as follows: The sensing network element judges the sensing capability of the sensing node, and when the sensing capability of the sensing node meets the preset sensing capability, sends the sensing configuration information (i.e., the fourth indication information) of the sensing node to the network device.

[0134] As a possible implementation manner, the implementation process of the sensing network element judging the sensing capability of the sensing node may be: If the sensing network element determines that the sensing node can perform communication sensing as a sensing node in the actual sensing scenario, the sensing network element can determine that the sensing capability of the sensing node meets the preset sensing capability.

[0135] As another possible implementation manner, the implementation process of the sensing network element judging the sensing capability of the sensing node may be: When the sensing network element determines that the sensing node has the ability to send sensing signals and the ability to receive echo signals, the sensing network element can obtain the sensing requirements in the actual sensing scenario (for example, the sensing type and the accuracy of the sensing type required in the actual sensing scenario), and when the sensing type and the accuracy of the sensing type that the sensing node can sense meet the above sensing requirements, determine that the sensing capability of the sensing node meets the preset sensing capability.

[0136] It can be understood that the network device determines the sensing capability and / or data processing capability of the sensing node, and sends the sensing capability and / or data processing capability of the sensing node to the sensing network element, so that the sensing network element can determine whether to configure sensing resources for the sensing node based on the sensing capability and / or data processing capability of the sensing node. When the sensing network element determines that the sensing capability of the sensing node meets the preset sensing capability, the sensing network element can send the sensing configuration information to the sensing node, so that the sensing node can obtain sensing resources based on the above sensing configuration information, and then can use the above sensing resources to implement the sensing function.

[0137] It should be noted that when the sensing network element determines that the sensing capability of the sensing node does not meet the preset sensing capability, the sensing network element can determine that the sensing node cannot perform communication sensing in the actual sensing scenario. Therefore, the sensing network element can not configure sensing resources for the sensing node.

[0138] In a possible embodiment, the sensing configuration information includes at least one of the following: the sensing node type, the resources configured for the sensing signal, or the resources configured for the echo signal.

[0139] Exemplarily, the sensing node type may include a transmitting (transport, Tx) node and a receiving (receive, Rx) node.

[0140] As an example, as shown in Table 2 below, Table 2 illustrates at least one of IE / Group Name, Presence, Range, or IEtype and reference. When the fourth indication information is used to indicate the sensing configuration information of the terminal device, the fourth indication information may include: Message Type, UE identity document (ID), Sensing Node, Sensing Resource Configuration, and UE processing. The above is only an exemplary description of the fourth indication information, and the fourth indication information may also include other information, which is not limited in this application.

[0141] Among them, the IE type and reference of the UE ID can be represented by combining the AMF UE next generation application protocol (NGAP) ID and the RAN UE NGAP ID, or can be represented by the global ID of the UE. Sensing Node can be used to represent the sensing node type, including Tx nodes and Rx nodes. Sensing Resource Configuration can be used to represent the resources configured for the sensing signal, or the resources configured for the echo signal. UE processing can be used to represent whether the UE processes the original sensing data.

[0142] Exemplarily, when the Range of UE processing is True, the sensing network element determines that the UE processes the original sensing data. When the Range of UE processing is False, the sensing network element determines that the UE does not process the original sensing data.

[0143] Table 2

[0144]

[0145] It should be noted that the above UE can be used to represent the terminal device in the embodiments of the present application. M is mandatory and can be used to represent mandatory.

[0146] As another example, when the fourth indication information is used to indicate the sensing configuration information of the network device, the fourth indication information may be the sensing configuration information of the network device sent by the sensing network element to the network device. As shown in Table 3 below, Table 3 describes at least one of IE / Group Name, Presence, Range, or IE type and reference. The sensing configuration information of the network device may include: Message Type, Global RAN Node ID, Sensing Node, and Sensing Resource Configuration. Among them, Sensing Node can be used to represent the sensing node type, including Tx nodes and Rx nodes. Sensing Resource Configuration can be used to represent the resources configured for the sensing signal or the resources configured for the echo signal. The above is only an exemplary description of the sensing configuration information of the network device, and the sensing configuration information of the above network device may also include other information, and the present application does not make any restrictions on this.

[0147] Table 3

[0148]

[0149]

[0150] It should be noted that M is mandatory and can be used to represent mandatory. In a possible embodiment, when the fourth indication information is used to indicate the sensing configuration information of the terminal device, the network device sends the sensing configuration information of the terminal device to the terminal device. Correspondingly, the terminal device receives the sensing configuration information of the terminal device from the network device.

[0151] As a possible implementation, the network device directly sends the sensing configuration information of the terminal device sent by the sensing network element to the terminal device, or the network device may encapsulate the sensing configuration information of the terminal device sent by the sensing network element and send the encapsulated information to the terminal device. The terminal device receives the above sensing configuration information of the terminal device.

[0152] It can be understood that since the perception configuration information of the terminal device includes information on whether the terminal device processes the original perception data, after the terminal device receives the perception configuration information of the above terminal device, it can determine whether it is necessary to process the original perception data, and can determine whether to report the first indication information or the second indication information to the network device.

[0153] In the data transmission method provided by the embodiments of the present application, the network device sends the third indication information to the perception network element and receives the fourth indication information from the perception network element. That is to say, the network device can report the perception ability and / or data processing ability of the perception node to the perception network element. In this case, when the perception network element receives the above perception ability and / or data processing ability, it can select the perception node that perceives the perception target and send the perception configuration information to the network device, so that the perception node can perceive the perception target, avoiding the situation where the perception ability and / or data processing ability of the perception node that perceives the perception target is poor, enabling the perception node to process the perception signal in a timely manner, and thus avoiding the problem of poor perception effect. In a possible embodiment, when the terminal device reports the perception ability and data processing ability of the terminal device to the perception network element through the network device, the perception network element can determine whether the terminal device can process the original perception data, and when it is determined that the terminal device cannot perceive the above original perception data, it instructs the terminal device to report the original perception data to the network device, so that the network device processes the original perception data. Figure 5 Based on the method embodiment shown, this embodiment provides a possible implementation manner. Combining Figure 5 with Figure 6 as shown, the implementation process of the terminal device reporting the original perception data to the network device can be determined through the following S601 to S602.

[0154] S601. The terminal device sends the first indication information to the network device. Correspondingly, the network device receives the first indication information from the terminal device.

[0155] Among them, the first indication information is used to indicate the original perception data of the echo signal. The first indication information is triggered when the data processing ability of the terminal device does not meet the first preset condition. The first preset condition includes that the duration of processing the original perception data is less than or equal to the first preset threshold, and / or the accuracy of processing the original perception data is greater than or equal to the second preset threshold.

[0156] It should be noted that the above echo signal can be a kind of perception signal. In the category of perception signals, the echo signal can be a sound wave or electromagnetic wave signal reflected by the perception target to provide information such as the object position, shape, and size of the perception target.

[0157] It can be understood that before the network device receives the first indication information from the terminal device, the network device can receive the sensing capability and data processing capability of the terminal device, and send the sensing capability and data processing capability of the terminal device to the sensing network element, so that the sensing network element can configure the terminal device based on the sensing capability and data processing capability of the terminal device, and then it can be determined whether the terminal device sends the first indication information to the network device.

[0158] In a possible implementation manner, the implementation process of the above S601 can be as follows: When the terminal device is a sensing node, the terminal device can send multiple sensing signals. After being scattered by the environment or the sensing target, the terminal device receives the above scattered echo signals. The terminal device can directly send the original sensing data of the received echo signals (i.e., the first indication information) to the network device. Correspondingly, the network device receives the first indication information from the terminal device.

[0159] Exemplarily, the scattered echo signal received by the above terminal device can be the in-phase / quadrature (I / Q) stream of the echo signal, that is, the first indication information sent by the terminal device to the network device can be the I / Q stream of the echo signal.

[0160] In a possible implementation manner, the terminal device can send the data processing capability of the terminal device to the network device, and the network device sends the data processing capability of the terminal device to the sensing network element. The sensing network element receives the data processing capability of the terminal device, and determines whether the terminal device can process the original sensing data of the echo signal based on the data processing capability of the terminal device and the first preset condition. When the sensing network element determines that the terminal device cannot process the above original sensing data, the terminal device can send the original sensing data of the echo signal (i.e., the first indication information) to the network device. Correspondingly, the network device receives the first indication information from the terminal device.

[0161] The following details the implementation process of the sensing network element determining whether the terminal device can process the original sensing data based on the data processing capability of the terminal device and the first preset condition.

[0162] As a possible implementation, the process for the sensing network element to determine whether a terminal device can process raw sensing data based on the data processing capability of the terminal device and a first preset condition can be as follows: The sensing network element determines, based on the data processing capability of the terminal device, the amount of raw sensing data processed by the terminal device within a unit time period (i.e., the speed at which the terminal device processes raw sensing data), and determines the amount of raw sensing data that needs to be processed in the actual sensing scenario. The sensing network element determines the ratio of the amount of raw sensing data that needs to be processed in the actual sensing scenario to the speed at which the terminal device processes raw sensing data as the processing duration required for the terminal device to process the raw sensing data in this actual sensing scenario. In the case where the above-mentioned required processing duration is greater than the first preset threshold, the sensing network element can determine that the data processing capability of the terminal device does not meet the first preset condition and determine that the terminal device cannot process the raw sensing data.

[0163] Exemplarily, the unit time period can be the time of one time unit (e.g., 1 second). The above is only an exemplary description of the unit time period. The above-mentioned unit time period can also be the time of other time units (e.g., 1 hour), and this application does not make any restrictions on this.

[0164] As an example, the sensing network element can set the first preset threshold according to the sensing speed requirement or experience of the actual sensing scenario. For example, the sensing network element can set the first preset threshold to 3 minutes. The above is only an exemplary description of the first preset threshold, and the above-mentioned first preset threshold can also be other values (e.g., 5 minutes), and this application does not make any restrictions on this.

[0165] As another possible implementation, the process for the sensing network element to determine whether a terminal device can process raw sensing data based on the data processing capability of the terminal device and a first preset condition can also be as follows: The sensing network element determines, based on the data processing capability of the terminal device, the amount of raw sensing data processed by the terminal device within a preset duration, and determines the amount of raw sensing data that needs to be processed in the actual sensing scenario. If the amount of raw sensing data processed by the terminal device within the preset duration is less than the amount of raw sensing data that needs to be processed in the actual sensing scenario, the sensing network element can determine that the data processing capability of the terminal device does not meet the first preset condition and determine that the terminal device cannot process the raw sensing data.

[0166] Exemplarily, the above-mentioned preset duration can be the first preset threshold. The above is only an exemplary description of the preset duration, and the above-mentioned preset duration can also be other values, and this application does not make any restrictions on this.

[0167] As another possible implementation, the process for the sensing network element to determine whether the terminal device can process the original sensing data based on the data processing capability of the terminal device and the first preset condition can also be as follows: The sensing network element determines the accuracy that the terminal device can achieve in processing the original sensing data based on the data processing capability of the terminal device. When the accuracy that the terminal device can achieve in processing the original sensing data is less than the second preset threshold, it is determined that the data processing capability of the terminal device does not meet the first preset condition, and it is determined that the terminal device cannot process the original sensing data.

[0168] Exemplarily, the sensing network element can set the second preset threshold according to the sensing accuracy requirement or experience of the actual sensing scenario. For example, the sensing network element can determine the accuracy required to process the original sensing data in the actual sensing scenario as the second preset threshold. The above is only an exemplary description of the second preset threshold, and the second preset threshold can also be other values, and the present application does not make any restrictions on this.

[0169] As another possible implementation, the process for the sensing network element to determine whether the terminal device can process the original sensing data based on the data processing capability of the terminal device and the first preset condition can also be as follows: The sensing network element determines the amount of data (i.e., the speed at which the terminal device processes the original sensing data) that the terminal device processes the original sensing data within a unit time period and the accuracy that the terminal device can achieve in processing the original sensing data, and determines the amount of data of the original sensing data that needs to be processed in the actual sensing scenario and the accuracy required to process the above original sensing data. The sensing network element determines the ratio of the amount of data of the original sensing data that needs to be processed in the actual sensing scenario to the speed at which the terminal device processes the original sensing data as the processing duration required for the terminal device to process the original sensing data in this actual sensing scenario, and determines the accuracy required to process the original sensing data in the actual sensing scenario as the second preset threshold. When the required processing duration is greater than the first preset threshold and the accuracy that the terminal device can achieve in processing the original sensing data is less than the second preset threshold, the sensing network element can determine that the data processing capability of the terminal device does not meet the first preset condition, and determine that the terminal device cannot process the original sensing data.

[0170] As another possible implementation, the process for the sensing network element to determine whether the terminal device can process the original sensing data based on the data processing capability of the terminal device and the first preset condition may also be as follows: The sensing network element determines, based on the data processing capability of the terminal device, the amount of the original sensing data that the terminal device can process within a preset time period and the accuracy that the terminal device can achieve in processing the original sensing data, and determines the amount of the original sensing data that needs to be processed in the actual sensing scenario. If the amount of the original sensing data that the terminal device can process within the preset time period is less than the amount of the original sensing data that needs to be processed in the actual sensing scenario, and the accuracy that the terminal device can achieve in processing the original sensing data is less than a second preset threshold, the sensing network element may determine that the data processing capability of the terminal device does not meet the first preset condition and determine that the terminal device cannot process the original sensing data.

[0171] It should be noted that the above is only an exemplary description of the process for the sensing network element to determine whether the terminal device can process the original sensing data based on the data processing capability of the terminal device and the first preset condition. The process for the sensing network element to determine whether the terminal device can process the original sensing data based on the data processing capability of the terminal device and the first preset condition may also include other implementation processes, and the present application places no restrictions thereon.

[0172] It can be understood that when the data processing capability of the terminal device does not meet the first preset condition, the time taken for the terminal device to process the original sensing data is relatively long, and / or the accuracy of the terminal device in processing the original sensing data is relatively low, resulting in a relatively poor processing capability of the terminal device for the original sensing data. Therefore, the terminal device reports the original sensing data to the network device, and the network device processes the above original sensing data, which can avoid the problem that the effect of determining the sensing data is poor due to the poor effect of processing the original sensing data, and thus can improve the sensing effect.

[0173] In one example, when the data processing capability of the terminal device does not meet the first preset condition, the terminal device may also report the original sensing data to other processors. The present application places no restrictions thereon.

[0174] In one possible implementation, the network device or other processor that receives the original sensing data from the terminal device may meet the condition that the time taken to process the original sensing data is less than or equal to a first preset threshold, and the accuracy of processing the original sensing data is greater than or equal to a second preset threshold (i.e., the data processing capability does not meet the first preset condition), which can effectively improve the effect of processing the original sensing data and thus improve the sensing effect.

[0175] As a possible implementation, when the data processing capability of the terminal device meets the first preset condition, the terminal device can process the above-mentioned original perception data and report the processed original perception data to the perception network element through the network device.

[0176] S602. The network device sends second indication information to the perception network element. Correspondingly, the perception network element receives the second indication information from the network device.

[0177] Wherein, the second indication information is used to indicate the perception data obtained after processing based on the original perception data.

[0178] As a possible implementation, before the network device sends the second indication information to the perception network element, the network device can process the original perception data to obtain the second indication information, or the network device can directly receive the second indication information from the terminal device.

[0179] In a possible implementation, the process of the network device determining the second indication information can be: when the terminal device cannot process the original perception data, the network device can receive the original perception data (i.e., the first indication information) of the echo signal from the terminal device and process the above-mentioned original perception data to obtain the processed perception data (i.e., the second indication information).

[0180] In another possible implementation, the process of the network device determining the second indication information can also be: when the terminal device can process the original perception data, the terminal device processes the original perception data to obtain the processed perception data and sends the above-mentioned processed perception data (i.e., the second indication information) to the network device. The network device can receive the second indication information from the terminal device.

[0181] It should be noted that when the data processing capability of the terminal device does not meet the first preset condition, the terminal device can process the original perception data to obtain the processed perception data and report the processed perception data to the network device, so that the network device can directly send the processed perception data to the perception network element.

[0182] It can be understood that when the data processing capability of the terminal device does not meet the first preset condition, the terminal device has a better processing ability for the original perception data. Therefore, the terminal device can process the original perception data to obtain the processed perception data and report the processed perception data to the network device. In this way, compared with the terminal device sending the original perception data to the network device, the data volume reported by the terminal device can be saved.

[0183] As a possible implementation, when the network device processes the original perception data, the implementation process of the network device processing the original perception data may include the following steps 1 to 5:

[0184] Step 1: The network device can filter the original perception data to remove the noise existing in the original perception data of the echo signal, so as to obtain the perception data of the echo signal with better signal quality, so that the perception data after removing the noise can accurately reflect the characteristics of the perception target.

[0185] Step 2: The network device can use a signal processing algorithm to judge the perception data of the above-mentioned echo signal after removing the noise to determine whether there is a perception target within the perception range of the network device.

[0186] Step 3: The network device can perform spectrum analysis, video analysis, etc. on the echo signal of the perception target through a signal processing algorithm to obtain information such as the speed, position, and shape of the perception target.

[0187] Step 4: The network device can extract and analyze the features of the above-mentioned echo signal of the perception target, and classify and identify according to the features of the perception target.

[0188] Step 5: The network device can parse the features of the above-mentioned identified perception target into actual physical quantities (for example, the speed and angle of the perception target, etc.), and determine the above-mentioned parsed actual physical quantities as the processed perception data.

[0189] Exemplarily, the signal processing algorithms used in the implementation process of the network device processing the original perception data may include technologies such as filtering, Fourier Transform (FFT), and correlation analysis. The above signal processing algorithms may also include other algorithms, and this application does not make any restrictions on this.

[0190] It should be noted that the above is only an exemplary description of the implementation process of the network device processing the original perception data. For different perception scenarios, the methods and signal processing algorithms for the network device to process the original perception data may be different, and this application does not make any restrictions on this.

[0191] As a possible implementation, when the terminal device processes the original perception data, the implementation process of the terminal device processing the original perception data can be understood by referring to the description at the corresponding position above (that is, the implementation process of the network device processing the original perception data), and will not be elaborated here.

[0192] In the data transmission method provided by the embodiment of the present application, the network device receives the first indication information from the terminal device and sends the second indication information to the sensing network element. That is to say, during the communication perception process of the terminal device, when the data processing capability of the terminal device does not meet the first preset condition (that is, the duration of processing the original perception data is less than or equal to the first preset threshold, and / or the accuracy of processing the original perception data is greater than or equal to the second preset threshold), the terminal device can send the original perception data of the received echo signal to the network device, and the network device processes the original perception data to obtain the processed perception data. In this way, when the terminal device cannot process the above original perception data or the processing effect of the terminal device on the above original perception data is poor, the network device processes the above original perception data to obtain the processed perception data, which can improve the processing effect of the original perception data and thus improve the perception effect.
