[0002] Communication sensing technology is to integrate communication technology and sensing technology to achieve the sensing of sensing targets while ensuring high-speed communication. During the communication sensing process, a network device can send multiple sensing signals, which are scattered by the environment or sensing targets and then received by the network device as the above-mentioned scattered multiple sensing signals (i.e., echo signals). The network device can process the above echo signals to obtain sensing data.

[0039] The information transmission method, device, and storage medium provided by an embodiment of this application will be described in detail below with reference to the accompanying drawings.

[0040] As used herein, the term "and / or" merely describes an association relationship between associated objects and indicates that three relationships may exist. For example, A and / or B may represent three cases: A exists alone, A and B exist simultaneously, and B exists alone.

[0041] The terms "first" and "second" and the like in the specification and drawings of this application are used to distinguish different objects, or to distinguish different processing of the same object, rather than to describe a specific order of objects.

[0042] Furthermore, the terms "including," "having," and any variations thereof, as used in the description of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or units is not limited to the listed steps or units, but may optionally include other steps or units not listed, or may optionally include other steps or units inherent to the process, method, product, or apparatus.

[0043] It should be noted that in the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being more preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0044] As an important technology in communication networks, communication and perception integration technology can enable the two independent functions of communication and perception 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, the communication system and its reference signals can be used to monitor and track perception targets (for example, unknown objects and known objects). Therefore, communication and perception integration technology can be regarded as a candidate technology for the sixth generation mobile communication technology (6G).

[0045] 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, and after being scattered by the environment or the sensing target, the first network device receives the multiple scattered sensing signals (i.e., echo signals). Another example is that in the network device sensing mode, the first network device can send multiple sensing signals, and after being scattered by the environment or the sensing target, the first network device and the second network device receive the multiple scattered echo signals. Another example is that in the network device sensing mode, the terminal device can send multiple sensing signals, and after being scattered by the environment or the sensing target, the network device receives the multiple scattered echo signals. Another example is that in the terminal device sensing mode, the network device can send multiple sensing signals, and after being scattered by the environment or the sensing target, the terminal device receives the multiple scattered echo signals. Another example is that in the terminal device sensing mode, the first terminal device can send multiple sensing signals, and after being scattered by the environment or the sensing target, the first terminal device and the second terminal device receive the multiple scattered echo signals. Another example is that in the terminal device sensing mode, the first terminal device can send multiple sensing signals, and after being scattered by the environment or the sensing target, the first terminal device receives the multiple scattered echo signals.

[0046] In a 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.

In this schematic diagram, the network architecture of a sensing system includes the following network element functional entities: radio access network ((radio) access network, (R) AN), user equipment (user equipment, UE), user plane function (user plane function, UPF), data network (data network, DN), and network element functional entities in the sensing system.

[0060] SMF accesses the above bus through the service-based interface Nsmf.

[0061] AUSF accesses the above bus through the service-based interface Nausf.

[0066] NEF accesses the above bus through the service-based interface Nnef.

[0067] AF accesses the above bus through the service-based interface Naf.

[0068] The above is a brief introduction to the network architecture of the perception system in this application.

[0069] During the communication sensing process, the network device may send multiple sensing signals. After being scattered by the environment or sensing target, the network device receives the scattered sensing signals (i.e., echo signals) and processes the echo signals to obtain sensing data.

[0070] However, after determining the network device that perceives the perception target, if the perception target moves, it is difficult to ensure that the determined network device has a good ability to process the echo signal. This may make it impossible to obtain the perception data well, resulting in poor perception of the perception target.

[0071] In view of this, an embodiment of the present application provides an information transmission method, in which a first network device sends first indication information to a perception network element, wherein the first indication information can be used to request the perception network element to configure perception resources for the first network device and a second network device that perceives a perception target together with the first network device, so that the first network device and the second network device can collaboratively perceive the perception target; or, the first indication information can also be used to request the perception network element to configure perception resources for the first network device, so that the first network device can perceive the perception target alone. Since, in the process of perceiving the perception target, the first network device can adaptively adjust the network device that perceives the perception target through the first indication information, the ability of the network device that perceives the perception target can be guaranteed as much as possible, thereby improving the effect of perceiving the perception target.

[0072] The technical solutions provided in the embodiments of the present application can be applied to various communication systems, for example, a 5G New Radio (NR) communication system, a future evolution system, or a multi-communication convergence system.

The sensing network element 302 may be used to manage the sensing operations of the first network device 301, such as receiving the first indication information of the first network device 301, participating in the negotiation process of cooperative sensing between the first network device 301 and the second network device, and sending down the sensing-related configuration information to the first network device 301 and the second network device. The naming of the sensing functional network element in the embodiments of this application is only exemplary, and the sensing functional network element may have other names, which are not limited herein.

[0080] Exemplarily, the perception network element 302 may also be responsible for perception services, for example, detecting and / or collecting perception data based on internal network requirements or requirements of perception service demanders, and may also provide perception services based on the perception data, such as providing perception services to perception service demanders, or optimizing the network internally based on the perception data. The perception network element 302 may be one of the core network elements, such as one of the 5G core network elements, or may not be a core network element, such as an access network device or an external application server.

The second network device is a network device that perceives a perception target together with the first network device, or the second network device is a network device that perceives a perception target independently.

[0100] In the information transmission method provided in the embodiment of the present application, the first network device sends a first indication message to the perception network element, wherein the first indication message can be used to request the perception network element to configure perception resources for the first network device and the second network device that perceives the perception target together with the first network device, so that the first network device and the second network device can collaboratively perceive the perception target; or, the first indication message can also be used to request the perception network element to configure perception resources for the first network device, so that the first network device can perceive the perception target alone; or, the first indication message can also be used to request the perception network element to configure perception resources for the second network device, so that the second network device can perceive the perception target alone. Since, in the process of perceiving the perception target, the first network device can adaptively adjust the network device that perceives the perception target through the first indication message, the ability of the network device that perceives the perception target can be guaranteed as much as possible, thereby improving the effect of perceiving the perception target.

[0101] The above S501 is described in detail below.

[0102] In a possible implementation, the implementation process of the above S501 may be: the first network device may determine the network device currently perceiving the perception target, and the network device perceiving the perception target after it moves when the perception target moves. If the network device currently perceiving the perception target is the first network device, and when the perception target moves, the network devices perceiving the perception target after it moves are the first network device and the second network device, the first network device requests the perception network element to configure perception resources for the first network device and the second network device. If the network devices currently perceiving the perception target are the first network device and the second network device, and when the perception target moves, the network device perceiving the perception target after it moves is the first network device, the first network device requests the perception network element to configure perception resources for the first network device.

[0103] The following describes in detail the first indication information in different situations in the embodiments of the present application.

[0104] In a possible embodiment, when a first network device senses a sensing target, a distance between a second network device and a predicted moving position is less than or equal to a first preset threshold, and a sensing capability of the second network device meets a sensing requirement, the first indication information is used to request a sensing network element to configure sensing resources for the first network device and the second network device. Alternatively, when the first network device and the second network device jointly sense a sensing target, a distance between the first network device and the predicted moving position is less than or equal to a first preset threshold, and a distance between the second network device and the predicted moving position is greater than the first preset threshold, the first indication information is used to request a sensing network element to configure sensing resources for the first network device.

[0105] As a possible implementation method, when the first network device no longer perceives the perception target and the first network device determines that the second network device perceives the perception target, the first indication information is used to request the perception network element to configure perception resources for the second network device, so that the second network device can perceive the perception target alone.

[0106] In one possible implementation, when the first network device and the second network device jointly perceive the perception target, the distance between the first network device and the predicted mobile position is greater than a first preset threshold, and the distance between the second network device and the predicted mobile position is less than or equal to the first preset threshold, the second network device can send resource request information to the perception network element, so that the perception network element can configure perception resources for the second network device.

[0107] The following describes in detail the implementation process of the first network device determining the second network device.

[0108] As a possible implementation manner, the implementation process of the first network device determining the second network device may include the following steps 1 to 3:

[0109] Step 1: The first network device determines a network device whose distance to the predicted moving position of the perception target is less than or equal to a first preset threshold as a candidate second network device.

[0110] It can be understood that the above-mentioned second network device to be selected may include one or more network devices, and this application does not impose any limitation on this.

[0111] In one possible implementation, step 1 may be implemented as follows: the first network device determines a predicted moving position of a perceived target and calculates a distance between network devices other than the first network device and the predicted moving position of the perceived target. The first network device determines as a candidate second network device a network device whose distance to the predicted moving position of the perceived target is less than or equal to a first preset threshold.

[0112] Exemplarily, the implementation process of the first network device calculating the distance between other network devices other than the first network device and the predicted moving position of the perceived target can be: the first network device obtains the location information of other network devices, and substitutes the predicted moving position of the perceived target and the location information of the above-mentioned other network devices into the distance formula to obtain the distance between the above-mentioned network devices and the predicted moving position of the perceived target.

[0113] In another possible implementation, step 1 may be implemented as follows: the first network device may determine a predicted moving position of the perceived target and determine a preset range based on the predicted moving position of the perceived target. The first network device may determine each of at least one network device within the preset range as a candidate second network device. The distance between each network device within the preset range and the predicted moving position of the perceived target is less than or equal to a first preset threshold.

[0114] Exemplarily, the first network device may determine each of the at least one network device within the preset range as a candidate second network device by: the first network device may obtain location information of other network devices other than the first network device, and determine the network devices within the preset range based on the location information of the other network devices. The first network device may determine the network devices within the preset range as the candidate second network devices.

[0115] In one possible implementation, the implementation process of the first network device determining the preset range can be: the first network device can determine a range with the predicted moving position of the perceived target as the center and the first preset threshold as the radius as the preset range, so as to ensure that the distance between the network device within the preset range and the predicted moving position of the perceived target is less than or equal to the first preset threshold.

[0116] In one example, the first network device may set a first preset threshold based on experience or the coverage range of the network device. For example, the first network device sets the first preset threshold to 1000 meters. The above is only an exemplary description of the first preset threshold. The first preset threshold may also be other values (e.g., 700 meters), and this application does not impose any limitation on this.

[0117] It can be understood that when the distance between the network device and the predicted moving position of the perceived target is less than or equal to the first preset threshold, the distance between the network device and the perceived target may be closer, so that the network device can better perceive the perceived target. When the distance between the network device and the predicted moving position of the perceived target is greater than the first preset threshold, the distance between the network device and the perceived target may be farther, and thus the network device's perception of the perceived target may be poor. Therefore, the first network device selects a network device whose distance to the predicted moving position of the perceived target is less than or equal to the first preset threshold to perceive the perceived target, which can avoid the problem of poor perception effect.

[0118] It should be noted that if, among the network devices other than the first network device, there is no network device whose distance to the predicted moving position of the perception target is less than or equal to the first preset threshold, or there is no network device other than the first network device within the above preset range (that is, there is no second network device to be selected), then the network device that perceives the moved perception target may only include the first network device. Therefore, the first network device can request the perception network element to configure perception resources for the first network device.

[0119] Step 2: The first network device determines the sensing capability of the second network device to be selected.

[0120] In a possible implementation, the implementation process of step 2 may be: the second network device to be selected sends the sensing capability of the second network device to the first network device. Correspondingly, the first network device receives the sensing capability from the second network device to be selected.

[0121] In one example, the perception capability may include at least one of the following: a perception indicator that can be perceived when perceiving a perception target, a perception accuracy that can be achieved when perceiving a perception target, or a perception service type supported when perceiving a perception target. The above is only an exemplary description of the perception capability, and the perception capability may also include other perception capabilities (for example, a perceivable distance), and this application does not impose any restrictions on this.

[0122] Step 3: Based on the sensing capability of the second network devices to be selected, the first network device determines, from the second network devices to be selected, a second network device whose sensing capability meets the sensing requirement as the second network device.

[0123] In one possible implementation, the implementation process of the above step 3 can be: the first network device can determine the perception requirements for perceiving the perception target when the perception target moves (that is, when the perception target is located at the predicted moving position), and determine the selected second network device whose perception capability meets the above perception requirements as the second network device.

[0124] Exemplarily, in the case where the candidate second network devices that meet the sensing requirements include multiple network devices, the first network device may compare the multiple candidate second network devices that meet the sensing requirements, and determine the candidate second network device with the strongest sensing ability as the second network device.

[0125] It can be understood that the first network device can obtain the sensing ability of the candidate second network devices, determine the candidate second network devices whose sensing ability meets the sensing requirements, and can also compare the sensing abilities of multiple candidate second network devices in the case where the candidate second network devices that meet the sensing requirements include multiple network devices, to obtain the second network device.

[0126] As another possible implementation manner, the implementation process of the first network device determining the second network device may further include the following steps 4 to 6:

[0127] Step 4: The first network device determines the network devices whose distance from the predicted moving position of the sensing target is less than or equal to the first preset threshold as the candidate second network devices.

[0128] It can be understood that the candidate second network devices may include one or more network devices, and the present application does not make any restrictions thereon.

[0129] In one possible implementation manner, the implementation process of the above step 4 can be understood by referring to the description at the corresponding position above (i.e., step 1), and will not be elaborated here.

[0130] Step 5: The first network device sends the sensing requirements to the candidate second network devices, and receives the second indication information from the candidate second network devices. The second indication information is used to indicate that the sensing ability of the candidate second network device meets the sensing requirements, or the second indication information is used to indicate that the sensing ability of the candidate second network device does not meet the sensing requirements.

[0131] As a possible implementation, the implementation process of step 5 above can be as follows: The first network device can determine the sensing requirements for sensing the sensed target after movement, and send the above sensing requirements to the candidate second network device. Correspondingly, the candidate second network device receives the above sensing requirements and determines whether its own sensing ability meets the above sensing requirements. When the candidate second network device determines that its own sensing ability meets the above sensing requirements, the second indication information sent by the candidate second network device to the first network device is used to indicate that the sensing ability of the candidate second network device meets the sensing requirements. When the candidate second network device determines that its own sensing ability does not meet the above sensing requirements, the second indication information sent by the candidate second network device to the first network device is used to indicate that the sensing ability of the candidate second network device does not meet the sensing requirements.

[0132] Step 6: The first network device, based on the above second indication information, determines the candidate second network device whose sensing ability meets the sensing requirements as the second network device.

[0133] As a possible implementation, the implementation process of step 6 above can be as follows: When the second indication information is used to indicate that the sensing ability of the candidate second network device meets the sensing requirements, the first network device determines the candidate second network device as the second network device.

[0134] Correspondingly, when the second indication information is used to indicate that the sensing ability of the candidate second network device does not meet the sensing requirements, the first network device determines that the candidate second network device is not the second network device.

[0135] In an example, if there are multiple second indication information in the second indication information received by the first network device above that are used to indicate that the sensing ability of the candidate second network device meets the sensing requirements, the first network device can compare the sensing abilities of the candidate second network devices corresponding to the above multiple second indication information, and determine the candidate second network device with stronger sensing ability as the second network device.

[0136] In another example, if there is no second indication information in the second indication information received by the first network device above that is used to indicate that the sensing ability of the candidate second network device meets the sensing requirements (that is, when the second indication information is all used to indicate that the sensing ability of the candidate second network device does not meet the sensing requirements), the first network device does not need to determine the second network device, and requests the sensing network element to configure sensing resources for the first network device.

[0137] The following details the implementation process for the first network device to determine whether the sensing ability of the candidate second network device meets the sensing requirements.

[0138] In one example, the perception requirements may include at least one of the following: a required perception service type for sensing a perception target, a required angle for sensing a perception target, a required speed for sensing a perception target, a required distance for sensing a perception target, or a required perception accuracy for sensing a perception target. The above is merely an exemplary description of the perception requirements, and this application does not impose any limitations thereon.

[0139] In one possible implementation, the implementation process of the first network device determining whether the perception capability of the second network device to be selected meets the perception requirements can be: the first network device can select the service type that can be supported when the second network device is perceived, and the perception service type required when perceiving the perception target, and when the supportable service type is the same as the above-mentioned perception service type required when perceiving the perception target, determine that the perception capability of the second network device to be selected meets the perception requirements.

[0140] In another possible implementation, the implementation process of the first network device determining whether the perception capability of the second network device to be selected meets the perception requirements can also be: the first network device can obtain the supportable angles of the second network device to be selected for perception, and the angles required when perceiving the perception target, and determine that the perception capability of the second network device to be selected meets the perception requirements when the above-mentioned supportable angles include the above-mentioned angles required when perceiving the perception target.

[0141] In another possible implementation, the implementation process of the first network device determining whether the perception capability of the second network device to be selected meets the perception requirements can also be: the first network device can obtain the speed that the second network device to be selected can support when perceiving, the perception accuracy that the second network device to be selected can achieve, the speed required when perceiving the perception target, and the perception accuracy required when perceiving the perception target, and determine that the perception capability of the second network device to be selected meets the perception requirements when the above-mentioned supportable speed includes the above-mentioned speed required when perceiving the perception target, and the achievable perception accuracy is the same as the required perception accuracy.

[0142] In another possible implementation, the implementation process of the first network device determining whether the perception capability of the second network device to be selected meets the perception requirements can also be: the first network device can obtain the service type that the second network device to be selected can support when perceiving, the distance that the second network device to be selected can support when perceiving, the perception service type required when perceiving the perception target, and the distance required when perceiving the perception target, and when the supportable service type is the same as the perception service type required when perceiving the above-mentioned perception target, and the supportable distance includes the distance required when perceiving the above-mentioned perception target, it is determined that the perception capability of the second network device to be selected meets the perception requirements.

[0143] It should be noted that for the implementation process of determining whether the sensing ability of the candidate second network device meets the sensing requirements as described above, it can be combined arbitrarily, and the present application does not impose any restrictions on this.

[0144] The following details the implementation process of the candidate second network device determining whether its own sensing ability meets the sensing requirements.

[0145] In a possible implementation manner, the candidate second network device can obtain the sensing requirements, and based on the sensing ability of the candidate second network device and the above sensing requirements, determine whether the sensing ability of the candidate second network device meets the sensing requirements.

[0146] Exemplarily, the implementation process of the candidate second network device determining whether its sensing ability meets the sensing requirements based on the sensing ability of the candidate second network device and the sensing requirements can be understood by referring to the description at the corresponding position above (i.e., the implementation process of the first network device determining whether the sensing ability of the candidate second network device meets the sensing requirements), and will not be elaborated here.

[0147] The following details the implementation process of the first network device determining the predicted moving position of the sensing target.

[0148] In a possible embodiment, the implementation process of the first network device determining the predicted moving position of the sensing target can be: The first network device monitors the sensing target to obtain the sensing information of the sensing target, and based on the sensing information, determines the predicted moving position of the sensing target. Among them, the sensing information includes the initial position, moving speed, and moving direction.

[0149] An example is that the above initial position can be the initial position of the sensing target obtained during the process of the first network device sensing the sensing target.

[0150] In a possible implementation manner, the implementation process of the first network device determining the predicted moving position of the sensing target can be: The first network device monitors the sensing target to determine the initial position, moving speed, and possible moving direction of the sensing target at the current moment. The first network device determines the possible moving distance of the sensing target in the above possible moving direction within a preset time period based on the moving speed of the sensing target at the current moment. The first network device combines the initial position of the sensing target and the possible moving distance of the sensing target in the above possible moving direction within the target time period to determine at least one predicted position where the sensing target may appear at a preset moment. The first network device determines each of the above at least one predicted position as the predicted moving position of the sensing target.

[0151] In another possible implementation, the process for the first network device to determine the predicted movement position of the perceived target may also include: the first network device determines the possible movement direction of the perceived target within a preset time period and the initial position of the perceived target at the current moment, and based on the possible movement direction of the perceived target within the preset time period and the initial position of the perceived target at the current moment, determines the predicted movement trajectory of the perceived target with the position of the perceived target at the current moment as the starting point. Based on the movement speed of the perceived target, the first network device determines the distance traveled by the perceived target along the predicted movement trajectory within the preset time period, and determines the position of the perceived target on the predicted movement trajectory at the preset moment. The first network device determines the position of the perceived target on the predicted movement trajectory at the preset moment as the predicted movement position of the perceived target.

[0152] In one example, the preset time may be a time after the current time, and the time period between the current time and the preset time may be a preset time period. The preset time period may be 10 minutes. The above is only an exemplary description of the preset time period, and the preset time period may also be other time periods (for example, 20 minutes), and this application does not impose any limitation on this.

[0153] It should be noted that the above is only an exemplary description of the implementation process of the first network device determining the predicted mobile position of the perceived target. The implementation process of the above first network device determining the predicted mobile position of the perceived target may also include other implementation processes, and this application does not impose any restrictions on this.

[0154] In one possible implementation, before the first network device determines the network device that perceives the moved perception target, the first network device can determine the network device that currently perceives the perception target, so that the first network device determines the current perception mode for perceiving the perception target and determines whether it is necessary to switch the perception mode for perceiving the perception target.

[0155] It should be noted that, when the first network device perceives the perception target, the first network device can determine that the perception mode for perceiving the perception target is an independent perception mode. When the first network device and the second network device perceive the perception target together, the first network device can determine that the perception mode for perceiving the perception target is a collaborative perception mode. Since the network device that perceives the perception target can be converted from the first network device to the first network device and the second network device, and the network device that perceives the perception target can be switched from the first network device and the second network device to the first network device, the first network device can flexibly switch the perception mode for perceiving the perception target, that is, the first network device can switch the perception mode from the independent perception mode to the collaborative perception mode, and can also switch the perception mode from the collaborative perception mode to the independent perception mode.

[0156] It can be understood that the first network device converts the sensing mode for sensing the sensing target into a cooperative sensing mode, which can also avoid the problem that the sensing target cannot be sensed when it moves, thereby realizing continuous sensing of the sensing target. When the first network device converts the sensing mode for sensing the sensing target into an independent sensing mode, it can prevent the request for sensing resources from being sent to the above-mentioned other network devices when the sensing target does not require other network devices to sense it, thereby avoiding resource idleness.

[0157] The following details the implementation process of the first network device for determining the network device currently sensing the sensing target.

[0158] In a possible implementation, since the network device currently sensing the sensing target may include the first network device, or the network device currently sensing the sensing target may include the first network device and the second network device, the first network device can determine whether the second network device is currently sensing the sensing target, and then determine the network device currently sensing the sensing target.

[0159] As an example, the first network device can obtain the current location information of the sensing target and the location information of the second network device, and substitute the current location information of the sensing target and the location information of the second network device into the distance formula to obtain the distance between the sensing target and the second network device. If the distance between the sensing target and the second network device is less than or equal to the first preset threshold, the first network device determines that the second network device is currently sensing the sensing target, and determines that the network device currently sensing the sensing target is the first network device and the second network device. If the distance between the sensing target and the second network device is greater than the first preset threshold, the first network device determines that the second network device is not currently sensing the sensing target, and determines that the network device currently sensing the sensing target is the first network device.

[0160] Combined with the above embodiments, when the network device currently sensing the sensing target is the first network device, the distance between the second network device and the predicted moving position is less than or equal to the first preset threshold, and the sensing ability of the second network device meets the sensing requirements, the first network device sends the first indication information to the sensing network element to request the sensing network element to configure sensing resources for the first network device and the second network device. When the network device currently sensing the sensing target is the first network device and the second network device, the distance between the first network device and the predicted moving position is less than or equal to the first preset threshold, and the distance between the second network device and the predicted moving position is greater than the first preset threshold, the first network device sends the first indication information to the sensing network element to request the sensing network element to configure sensing resources for the first network device.

[0161] The following details the first indication information in the embodiments of the present application.

[0162] In a possible embodiment, the first indication information includes at least one of the following: the reason for requesting sensing resources, the network device currently performing sensing on the sensing target, or sensing metrics; the sensing metrics include at least one of the following: speed, angle, or distance.

[0163] As an example, the first indication information may be a sensing resource request message sent by a first network device to a sensing network element. As shown in Table 1 below, Table 1 describes at least one of the information element / group name (IE / groupname), Presence, Range, or IE type and reference. The above sensing resource request message may include: Message Type, Cause, Current Sensing Mode, and Current Sensing Metrics. Among them, the current sensing metrics may include one or more of Distance, Angle, or Velocity. The above is only an exemplary description of the first indication information, and the first indication information may also include other information (for example, the type of resource to be configured (uplink reference signal resource or downlink reference signal resource)), and the present application does not impose any restrictions on this.

[0164] Table 1

[0165]

[0166] It should be noted that M stands for mandatory and can be used to indicate mandatory. Cause can be used to indicate the reason for requesting sensing resources, so that the sensing network element can distinguish the reason for requesting sensing resources and then be able to configure the corresponding sensing resources for the network device in a timely manner. Cause may include Object Mobility or User Equipment Mobility. Among them, Object Mobility can be used to indicate that the reason for requesting sensing resources is the movement of the sensing target, that is, the movement of the sensing target triggers the request for the sensing resources of the network device, and User Equipment Mobility can be used to indicate that the reason for requesting sensing resources is the movement of the terminal device, that is, the movement of the terminal device triggers the request for the sensing resources of the network device.

[0167] It can be understood that in the case where the reason for requesting the sensing resource is the movement of the sensing target, the sensing network element may preferentially configure the sensing resource for the network device that senses the moved sensing target, so that the network device that senses the moved sensing target can obtain the sensing resource in a timely manner and sense the sensing target.

[0168] In a possible implementation manner, the first network device may determine the network device that currently senses the sensing target, and in the case where the sensing target moves, determine the network device that senses the moved sensing target. In this way, during the process of the first network device requesting the sensing resource from the sensing network element, the first network device can determine the sensing resource that needs to be requested from the sensing network element, so that the sensing network element can configure the sensing resource for the corresponding network device.

[0169] In a possible embodiment, after the first network device determines the network device that senses the sensing target in the case where the sensing target moves, the first network device may send the first indication information to the sensing network element. Correspondingly, the sensing network element receives the above first indication information and sends the configuration information to the corresponding network device. Based on the method embodiment shown in Figure 5 In this embodiment, a possible implementation manner is provided. Combining Figure 5 , as Figure 6 shown, the implementation process of the sensing network element sending the configuration information to the network device can be determined by the following S601.

[0170] S601: When the first indication information is used to request the sensing network element to configure the sensing resource for the first network device and the second network device, the sensing network element sends the configuration information of the first network device to the first network device and sends the configuration information of the second network device to the second network device.

[0171] Or, when the first indication information is used to request the sensing network element to configure the sensing resource for the first network device, the sensing network element sends the configuration information of the first network device to the first network device.

[0172] Wherein, the configuration information is used to configure the sensing resource.

[0173] In a possible embodiment, the sensing resource includes at least one of the following: sensing reference signal, resource corresponding to the sensing reference signal, TRP, or sensing metric; the sensing reference signal is any one of a downlink positioning reference signal (PRS) and a channel state information-reference signal (CSI-RS).

[0174] In one example, the configuration information may be the configuration information of the first network device sent by the sensing network element to the first network device, or the configuration information may be the configuration information of the second network device sent by the sensing network element to the second network device. As shown in Table 2 below, Table 2 describes at least one of IE / group name, Presence, Range, or IE type and reference. The above configuration information may include Message Type, the selected type of sensing reference signal (CHOICE Sensing RS type), the TRP information list (TRP information List), and the sensing metrics (Sensing metrics). The above is only one example of the configuration information, and the above configuration information may also include other information, and the present application does not impose any restrictions on this.

[0175] Among them, CHOICE Sensing RS type is PRS or CSI-RS. When CHOICE Sensing RS type is PRS, the configuration information may include NR-DL-PRS-ResourceID. When CHOICE Sensing RS type is CSI-RS, the configuration information may include CSI-ResourceConfigID. The TRP information list may include TRP information items (TRP Information Item). The TRP Information Item may include PRS configuration (PRSConfiguration) or CSI-RS configuration (CSI-RS Configuration). The Sensing metrics may include at least one of the following: Distance, Angle, or Velocity. The PRS Configuration may include the configuration information of the PRS sent by the TRP, and the configuration information of the PRS sent by the TRP may include time domain, frequency domain, and period information. The CSI-RSConfiguration may include the configuration information of the CSI-RS sent by the TRP, and the configuration information of the CSI-RS sent by the TRP may include time domain, frequency domain, and period information.

[0176] It should be noted that the configuration information may include a perception reference signal and a resource for transmitting the perception reference signal. Since PRS and CSI-RS are downlink reference signals and are reference signals sent by the network device side, the perception reference signal may be a PRS or CSI-RS. In addition, the resource for transmitting the perception reference signal includes at least one of the following: time domain, frequency domain, sequence number, or quasi co-location (QCL).

[0178]

[0179]

[0180] It should be noted that O stands for optional and can be used to indicate optional.

[0181] As an example, the configuration information of the first network device sent by the perception network element to the first network device, or the configuration information of the second network device sent by the perception network element to the second network device may be:

[0182]

[0183]

[0184] As another example, the configuration information of the first network device sent by the perception network element to the first network device, or the configuration information of the second network device sent by the perception network element to the second network device may also be:

[0185]

[0186]

[0187] In one possible implementation, the perception network element may directly send the configuration information to the network device (e.g., the first network device and the second network device, or the first network device). The perception network element may also encapsulate the configuration information and send the encapsulated configuration information to the network device via the AMF.

[0188] It can be understood that when the first indication information is used to request the perception network element to configure perception resources for the first network device and the second network device, the perception network element sends the configuration information of the first network device to the first network device, and sends the configuration information of the second network device to the second network device. In this way, when multiple network devices receive the echo signal, the perception network element can uniformly configure corresponding resources for multiple network devices, thereby avoiding the problem of resource conflicts caused by multiple network devices using the same set of resources.

[0189] In the information transmission method provided by the embodiments of the present application, the sensing network element may determine the network device (i.e., the first network device, or the first network device and the second network device) that needs to sense resources based on the first indication information, and send corresponding configuration information to the network device that needs to sense resources, so that the network device can realize the sensing of the sensing target based on the above configuration information, thereby improving the sensing effect of the sensing target.

[0190] It can be understood that the above information transmission method can be implemented by an information transmission device. In order to implement the above functions, the information transmission device includes the corresponding hardware structure and / or software module for executing each function. Those skilled in the art should easily realize that, combining the modules and algorithm steps of each example described in the embodiments disclosed in this application, the disclosed embodiments of the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a certain function is executed in the way of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional technicians can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the disclosed embodiments of the present application.
