Description

Information transmission method, device and system Technical Field

[0001] The present application relates to the field of wireless communication perception, and in particular, to a method, device and system for information transmission. Background Art

[0002] In recent years, wireless sensing technology has attracted widespread attention in the academic community. Wireless sensing technology analyzes the changes in wireless signals during propagation and obtains the characteristics of the signal propagation space (channel) to achieve scene perception. The main function of a wireless communication system based on a cellular network is to exchange information between transceivers. The basic principle of the system operation is that the transmitter transmits a specific waveform signal, which is received by the receiving device after passing through the wireless channel. After signal processing, the signal transmitted by the transmitter is demodulated, and then the surrounding environment is perceived based on the signal. When the size of the moving target is larger than the resolution unit (distance resolution, angle resolution) of the detection device, the moving target can be regarded as an extended target, which can contain multiple scattering points at the same time. When the resolution of the detection device is high enough, the target outline can be distinguished by the scattering points.

[0003] However, current descriptions of moving targets typically only include basic attribute information, such as the target's position, velocity, scattering intensity, and micro-Doppler information. Consequently, these basic attributes are insufficient to fully capture the target's detailed characteristics, potentially preventing a complete representation of the target's information.

[0004] Summary of the Invention

[0005] The present application provides a method, device and system for information transmission, which can expand the information attributes used to characterize a moving target. Based on the indication information sent by the control node, the receiving node can select the first information attribute of interest to the control node from the expanded information attributes, and feed the selected information attribute back to the control node. Through an effective feedback information representation method, the information of the moving target can be more completely characterized.

[0006] In a first aspect, a method for information transmission is provided, which is applied to a first node in a cellular communication network, the method comprising: sending indication information to a second node, the indication information being used to indicate a first information attribute, the first information attribute comprising at least one of a quality attribute, an identity attribute, or a structural attribute, wherein the quality attribute information is used to indicate the reliability of perception information determined by the second node through a perception signal; and receiving feedback information from the second node, the feedback information carrying information on basic attributes and information on the first information attribute, the basic attribute information being used to determine the position and / or speed of a moving target.

[0007] By way of example, the first node may be a control node in a communication network, and the second node may be a receiving node in the communication network.

[0008] For example, after receiving the indication information, the second node processes the perception signal accordingly to obtain feedback information containing the basic attribute information and the first information attribute. Furthermore, while processing the perception signal, the second node also determines the perception information characterizing the moving target. This perception information may include the distance, angle, speed, and intensity of the moving target relative to the second node and / or the third node.

[0009] For example, the perception information may belong to the feedback information, and may be sent to the first node along with the feedback information, or may be sent directly to the first node independently.

[0010] Based on the above technical solution, not only are the information attributes used to characterize the moving target expanded, but the second node can also select the first information attribute that the first node needs or is interested in from the expanded information attributes based on the instruction of the first node, and send the information of the basic attribute and the information of the first information attribute to the first node in the form of feedback information. Moreover, the feedback information can more completely characterize the information of the moving target through an effective representation method, while also avoiding sending the information corresponding to the information attributes that the first node does not need or is not interested in in all the expanded information attributes to the first node, causing unnecessary transmission overhead.

[0011] In combination with the first aspect, in some implementations of the first aspect, the indication information is also used to indicate periodic information, and the periodic information is associated with the first information attribute and / or the basic attribute, and the periodic information is used to instruct the second node to periodically send feedback information.

[0012] In combination with the first aspect, in some implementations of the first aspect, the periodic information includes a first period and a second period, the first period is associated with the basic attribute, the quality attribute and the identity attribute, the second period is associated with the structural attribute, and the second period is larger than the first period.

[0013] For example, the number of time periods included in the above-mentioned period information is not limited to two, and may also include more than three time periods.

[0014] After the second node receives the indication information indicating the first information attribute and periodicity information, the second node periodically repeats the process of sending the first feedback information and the second feedback information, thereby periodically sending the corresponding feedback information to the first node. Based on this solution, the first node only needs to send the indication information to the second node once to continuously instruct the second node to send feedback information. Therefore, the first node does not need to repeatedly send the same indication information indicating the information attribute to the first node to obtain the feedback information corresponding to the corresponding data format required by the first node, thereby reducing the signaling overhead generated by sending the indication information.

[0015] Based on the above technical solution, the indication information can also indicate the time period for the second node to send feedback information including different information attributes. By associating the time period with the corresponding information attribute, the second node can be instructed to feedback information with the information attribute corresponding to the time period after a shorter time period for information with a higher update frequency; and can be instructed to feedback information with the information attribute corresponding to the time period after a longer time period for information with a lower update frequency. This increases the rationality of the second node's information feedback.

[0016] In combination with the first aspect, in some implementations of the first aspect, the indication information is sent to the second node via a control channel.

[0017] In combination with the first aspect, in some implementations of the first aspect, feedback information from the second node is received through a physical downlink shared channel (PDSCH), a physical uplink shared channel (PUSCH), or an Xn interface.

[0018] Based on the above technical solution, this solution can be combined with the existing transmission protocol, that is, this solution can be implemented based on the existing transmission protocol and transmission channel to reduce the implementation difficulty of this solution and increase the feasibility of the solution.

[0019] In combination with the first aspect, in certain implementations of the first aspect, the information on basic attributes includes: the position of the moving target, the speed of the moving target, and the moment when the second node receives the perception signal; the information on quality attributes includes at least one of the following: the angular resolution of the second node, the distance resolution of the second node, the speed resolution of the second node, the false alarm probability of the perception information, the confidence of the perception information, and the signal-to-noise ratio corresponding to the perception signal; the information on identity attributes includes: the type of the moving target and / or the identification of the moving target; the information on structural attributes includes: component information, and the component information is used to represent the components included in the moving target.

[0020] For example, the basic attribute information may further include: the location of the second node and / or the location of the third node, wherein the third node is used to send the perception signal.

[0021] Based on the above technical solution, the information of the basic attributes and the information of the first information attributes are associated through a specific data format, and each information attribute in the first information attribute is optional. A variety of combinations of information attributes can be derived to enable the control node to obtain information of interest, and even obtain the information carried by each minimum characteristic unit that constitutes the moving target, so that the feedback information can more completely characterize the information of the moving target through a more effective representation method.

[0022] In combination with the first aspect, in certain implementations of the first aspect, the component information includes unit information of the minimum characteristic unit constituting the component, and the unit information includes: the position of the minimum characteristic unit relative to the reference point of the moving target, the energy or amplitude corresponding to the minimum characteristic unit, the material corresponding to the minimum characteristic unit, and the speed of the minimum characteristic unit relative to the reference point of the moving target.

When the minimum feature unit is a surface element used to constitute a moving target, the unit information also includes the normal information of the surface element and the coordinates of multiple vertices of the surface element.

[0024] In combination with the first aspect, in some implementations of the first aspect, the unit information further includes a quality factor, and the quality factor is used to indicate the reliability of the unit information.

[0025] Based on the above technical solution, according to the needs of the first node, the feedback information can include the quality factor of the unit information corresponding to each minimum characteristic unit, thereby helping the first node to perform more accurate and reasonable perception analysis of the motion target based on the feedback information.

[0026] In combination with the first aspect, in certain implementations of the first aspect, the number of identifications of moving targets is greater than or equal to one.

[0027] Based on the above technical solution, it is helpful for the first node to accurately identify multiple different moving targets with similar positions and shapes at the current moment.

[0096] Moving target perception mainly uses the Doppler generated by target motion to distinguish moving targets from static environments.

[0097] FIG1 is a schematic diagram of a moving target perception scenario.

[0098] As shown in Figure 1, the scenario includes a base station (BS) and user equipment (UE). The UE acts as a transmitting device, transmitting a transmission signal to a moving target within the sensing area. The transmission signal is acted upon by the moving target and continues to be transmitted in the form of a sensing signal, which is then received by the BS.

[0099] In some possible embodiments, the above-mentioned effect includes reflection, diffraction or scattering.

[0100] The BS then determines sensing information about the moving target based on the sensing signal. Furthermore, in this scenario, a control node is required to receive the sensing information determined by the BS and sense the moving target based on this sensing information to determine its location, speed, and even type, such as whether it is a car or a non-motorized vehicle. In this example, the control node can be located in the BS.

[0101] In the above process, after receiving the perception signal, the BS performs signal processing on the perception signal to generate corresponding perception information. The perception information can be represented by a RV two-dimensional map.

[0102] FIG2 is a schematic diagram of a two-dimensional RV map.

[0103] Referring to FIG2 , it can be seen that the above-mentioned perception information includes the position information, speed information and intensity information of the moving target. The data format of the perception information can be {position information, speed information, intensity information}, wherein the position information can be the three-dimensional space coordinates representing the moving target, and the coordinates can be the coordinates {x, y, z} in the Cartesian coordinate system or the coordinates {r, θ, φ} in the polar coordinate system; the speed information can be the speed representing the moving target. Since the speed has directionality, the speed can also be the speed expressed in the Cartesian coordinate system {v x ,v y ,v z}, or the velocity {v r ,v θ ,v φ Intensity information can be the energy intensity corresponding to the point cloud representing the moving target, which can be used to characterize the target's surface material. In addition to the aforementioned {position information, velocity information, and intensity information} features, micro-Doppler can also be used to distinguish target types. For example, the rotation of a moving car's wheels generates micro-Doppler, which can be used to distinguish whether the moving target is a car or a non-motorized vehicle. Therefore, the perception information corresponding to a moving target can be further expanded to {position information, velocity information, intensity information, and micro-Doppler information}.

[0104] Furthermore, when the size of a moving target is larger than the resolution unit (range resolution, angular resolution) of the BS detection device, the moving target can be considered an extended target, which can simultaneously contain multiple scattering points. When the resolution of the detection device is sufficiently high, the target outline can be distinguished by the scattering points. Furthermore, the detection device can actually determine some additional information about the moving target. However, in current wireless sensing technologies, even if the resolution of the detection device is sufficiently high, the final perception information determined only includes position information, velocity information, intensity information, and micro-Doppler information. This not only fails to display the extended feature information of the target object that should be displayed, but also results in a certain degree of performance waste of the detection device. Furthermore, in actual observation scenarios, multiple moving targets with similar features may exist simultaneously. For example, two cars may appear at the same time, and the motion paths of multiple targets may intersect in space. In this case, the perception information based on the above data format cannot distinguish multiple targets with similar shapes and at similar distances.

[0105] FIG3 is a schematic diagram of the cross-movement of multiple similar moving objects.

[0106] As shown in Figure 3, this intersecting path is used to represent the motion paths of two similar moving targets. This intersecting path can be divided into four segments. Assuming that moving target 1 starts from the endpoint of segment 1, moving target 1 can have the following two path combinations: segment 1 + segment 4, or segment 1 + segment 2. Assuming that moving target 2 starts from the endpoint of segment 3, moving target 2 can have the following two path combinations: segment 3 + segment 4, or segment 3 + segment 2. Therefore, if the perception information corresponding to moving targets 1 and 2 is presented in the above data format, the motion paths of moving targets 1 and 2 cannot be effectively distinguished based on this perception information.

[0107] In view of this, an embodiment of the present application proposes a method, device and system for information transmission, wherein the perception data for characterizing the characteristics of a moving target transmitted based on this method is presented through the mobile target feature representation method proposed in an embodiment of the present application, that is, an embodiment of the present application proposes to use indication information from a control device to accordingly expand the information attributes about the moving target in the perception data, thereby sending the information of interest to the control device to the control node, and through an effective information representation method, the information of the moving target can be more completely characterized.

[0130] The communication system 1100 includes: a base station, which also includes the above-mentioned transmitting node, receiving node and the above-mentioned control node.

[0131] FIG12 is a schematic diagram of a communication system 1200 proposed in an embodiment of the present application.

[0132] The communication system 1200 includes: a terminal device, which also includes the above-mentioned transmitting node, receiving node and the above-mentioned control node.

[0133] In some possible embodiments, a perception area may include multiple transmitting nodes, multiple receiving nodes, and even multiple control nodes. The embodiments of the present application do not limit the number of transmitting nodes, receiving nodes, and control nodes in a perception area.

[0134] Based on any of the above communication systems, an embodiment of the present application also proposes a corresponding method for information transmission.

[0135] Figure 13 is a flow chart of a method 1300 for information transmission according to an embodiment of the present application. The method can be applied to a second node in a cellular communication network, and the second node can be a receiving node in any of the above communication systems.

[0136] S1310: Receive indication information from a first node, where the indication information is used to indicate a first information attribute.

[0137] The first information attribute includes at least one of a quality attribute, an identity attribute, or a structure attribute, and the quality attribute information is used to indicate the reliability of the perception information determined by the second node through the perception signal. In addition, the first node can be a control node in any of the above communication systems.

[0138] S1320: Send feedback information to the first node according to the perception signal and the indication information.

[0139] Among them, the feedback information carries information of basic attributes and information of first information attributes. The information of basic attributes is used to determine the position and / or speed of the moving target. The perception signal is an echo signal transmitted by a third node and acted upon by the moving target. The third node can be a transmitting node in any of the above-mentioned communication systems.

[0140] In some possible embodiments, the sensing signal is acted upon by the moving target and then sent to the second node in the form of an echo signal.

[0141] In some possible embodiments, after receiving the indication information, the second node will take corresponding processing measures for the above-mentioned perception signal to obtain feedback information carrying the information of the above-mentioned basic attributes and the information of the first information attribute. In addition, in the process of the second node processing the above-mentioned perception signal, the perception information used to characterize the above-mentioned moving target will also be determined. The perception information may include the distance, angle, speed and intensity of the moving target relative to the second node and / or the third node, wherein the intensity of the moving target has the following meaning: after the echo signal of the moving target is processed by the second node, the corresponding moving target can be found on the RV two-dimensional map as shown in Figure 2. Whether a certain point in the RV two-dimensional map is a moving target can be determined based on whether the intensity of this point is higher than a preset threshold. When the intensity of the point is higher than the preset threshold, it can be considered that there is a moving target corresponding to the distance and speed of the point, and the intensity is the intensity value corresponding to the point on the RV two-dimensional map. Based on this, assuming that the distance, angle, speed and intensity can be expressed as {r, θ, v, A} respectively, it can be understood that there is a moving target in the space, the distance relative to the second node and / or the third node is r, the angle is θ, the speed is v, and the intensity of the echo signal after processing after the action of the moving target is A.

[0142] Among them, considering that the Doppler information corresponding to the moving target is determined by the moving speed and wavelength of the moving target, the speed of the moving target relative to the second node and / or the third node in the above perception information can also be replaced by the Doppler information corresponding to the moving target.

[0143] In some possible embodiments, the perception information may belong to the feedback information, and may be sent to the first node along with the feedback information, or may be sent directly to the first node independently.

[0144] Based on the above technical solution, not only are the information attributes used to characterize the moving target expanded, but the second node can also select the first information attribute that the first node needs or is interested in from the expanded information attributes based on the instruction of the first node, and send the information of the basic attribute and the information of the first information attribute to the first node in the form of feedback information. Moreover, the feedback information can more completely characterize the information of the moving target through an effective representation method, while also avoiding sending the information corresponding to the information attributes that the first node does not need or is not interested in in all the expanded information attributes to the first node, causing unnecessary transmission overhead.

[0145] In some possible embodiments, before the second node receives the sensing signal, the following operations may be further performed:

[0146] The third node sends notification signaling to the second node so that the second node establishes a perception link. The notification signaling can also notify the second node of time information, frequency information, and beam resource information used for perception, or notify the second node of the above-mentioned various information used for perception through another notification signaling. The notification signaling can be carried by radio resource control (RRC) signaling or downlink control information (DCI).

[0147] Then, the third node generates and sends a perception signal according to the time information, frequency information and beam resource information for perception notified to the second node. The perception signal can be sent through the air interface and, through the action of the moving target, such as reflection, diffraction or scattering, is finally received by the second node in the form of an echo signal and signal processing is performed on the perception signal.

[0148] When the resolution of the second node detection device is high enough, based on the perception signal, in addition to the position information, speed information, corresponding scattering point energy intensity information and micro-Doppler information of the moving target, the information of the first information attribute can also be obtained.

[0149] Figure 14 is a schematic diagram of a data format for feedback information proposed in an embodiment of the present application. The smallest characteristic unit of the perception data is the individual points in the point cloud that constitutes the moving target. It should be understood that when the smallest characteristic unit is a point, the second node will determine a set of point cloud data based on the perception signal, and the specific information included in the point cloud data can be displayed through a point cloud image.

[0150] In some possible embodiments, the basic attribute information includes: the position of the moving target, the speed of the moving target, and the time when the second node receives the perception signal;

[0151] The basic attribute information may further include: the position of the second node and / or the position of the third node.

[0152] It should be understood that the position and / or speed of the moving target can be determined based on the position of the moving target, the speed of the moving target, the time when the second node receives the perception signal, the position of the second node and the position of the third node, wherein the position of the moving target can be a relative position relative to the second node or the third node, or an absolute position in the geodetic coordinate system; the speed of the moving target can be a relative speed relative to the second node or the third node, or an absolute speed.

[0153] The quality attribute information includes at least one of the following: an angle resolution of the second node, a distance resolution of the second node, a speed resolution of the second node, a false alarm probability of the perception information, a confidence level of the perception information, and a signal-to-noise ratio corresponding to the perception signal;

[0154] Among them, the false alarm probability of the perception information and the confidence of the perception information belong to the quality factor corresponding to the perception information, and the signal-to-noise ratio corresponding to the perception signal belongs to the quality factor corresponding to the perception signal.

[0155] The identity attribute information includes: the type of the moving target and / or the identification of the moving target;

[0156] The information of the structural attributes includes: component information, where the component information is used to indicate the components included in the moving object.

[0157] In some possible embodiments, the position and speed of the moving object may be the position and speed corresponding to a reference point on the moving object, wherein the reference point may be any sampling point, centroid, or center point on the moving object.

[0158] In some possible embodiments, the moment when the second node receives the perception signal may be a timestamp in a time system, so the moment when the second node receives the perception signal is timestamp information.

[0159] In some possible embodiments, the types of moving targets may include: passenger cars, cars, trucks, buses, etc., and the present application does not limit the specific types of moving targets. The types of moving targets may be represented by a string of digitally encoded characters as shown in Table 1 below.

[0160] Table 1

[0161] Of course, when there are many types, the number of bits used to represent the characters of the target type can be expanded, for example, using three digits to represent, for example, truck: 100.

[0162] Similarly, using the bus as an example, a bus-type moving object can also include the following component information: wheels, roof, and body. The component information in the structural attributes can then be represented by a string of digitally encoded characters as shown in Table 2 below. Table 2 represents the component information corresponding to a bus-type moving object.

[0163] Table 2

[0164] Of course, when there are many component types, the number of bits of characters used to represent component information can be expanded, for example, using three digits to represent, axle: 100.

[0165] In some possible embodiments, the type of the moving object may be further associated with the component information in the structural attributes. For example, Tables 1 and 2 above are used to indicate that the feedback information includes the type and component information of the moving object. If the encoded feedback information includes field 0000, then this field indicates that the feedback information includes information about the wheels of the bus. Similarly, field 0010 indicates that this feedback information includes information about the bus body. And so on.

[0166] In some possible embodiments, the identification information of the above-mentioned moving target can be an identity document (ID) number, for example, it can be a digital identification such as 1, 2, 3, or an alphabetic identification such as A, B, C, or a combination of numbers and letters.

[0167] As shown in reference figure 14, for a moving target, the moving target can be composed of at least one component, so the feedback information can include multiple component information, for example, component information 1 is used to represent the roof, component information 2 is used to represent the body, and so on, until component information N is also used to represent a component of the moving target, and N is greater than 2. Each component can be composed of multiple points, for example, point 1, point 2 to point N, and N is greater than 2. Then, each point can also carry corresponding unit information, and the unit information can be a point information, and the point information includes: the position of the point relative to the reference point of the moving target, the energy or amplitude corresponding to the point, the material corresponding to the point, and the speed of the point relative to the reference point of the moving target. Among them, the reference point of the moving target can be any sampling point, centroid or center point on the moving target, and the embodiments of the present application are not limited to this.

[0168] In some possible embodiments, the above basic attributes are mandatory information attributes, and the above three attributes included in the first information attribute are optional information attributes.

[0169] Based on the above technical solution, the information of the basic attributes and the information of the first information attributes are associated through a specific data format, and each information attribute in the first information attribute is optional. A variety of combinations of information attributes can be derived to enable the control node to obtain information of interest, and even obtain the information carried by each point in the point cloud that constitutes the moving target, so that the feedback information can more completely characterize the information of the moving target through a more effective representation method.

[0170] In some possible embodiments, the aforementioned minimum feature unit may also be a facet used to construct a moving target. A facet (mesh), also known as a patch, grid, or polygon, is a planar region in three-dimensional space. The shape of this planar region is typically triangular, but other polygons are also possible. A facet is typically used to describe a planar region on the surface of a target object. Multiple facets are spliced ​​together to form a facet set. Similar to the aforementioned point cloud, this facet set can also be used to represent relevant information about the target object.

[0171] Figure 15 is a schematic diagram of another feedback information data format proposed in an embodiment of the present application. The smallest characteristic unit of the perception data is a facet used to constitute a moving target. It should be understood that when the smallest characteristic unit is a facet, the second node will determine a set of facet metadata based on the perception signal, and the specific information included in the facet metadata can be displayed through the facet image.

[0172] In some possible embodiments, the basic attribute information includes: the position of the moving target, the speed of the moving target, and the time when the second node receives the sensing signal;

[0173] The basic attribute information may further include: the position of the second node and / or the position of the third node.

[0174] The quality attribute information includes at least one of the following: an angle resolution of the second node, a distance resolution of the second node, a speed resolution of the second node, a false alarm probability of the perception information, a confidence level of the perception information, and a signal-to-noise ratio corresponding to the perception signal;

[0175] The identity attribute information includes: the type of the moving target and / or the identification of the moving target;

[0176] The information of the structural attributes includes: component information, and the component information is used to indicate the components included in the moving target.

[0177] It should be understood that when the minimum characteristic unit is a face element, the above-mentioned quality attribute information, identity attribute information, and structural attribute information are the same as the content included in the data structure shown in Figure 14 above. Therefore, in this embodiment, the expansion of these three aspects of information attributes is detailed in the corresponding embodiment of Figure 14 above, and will not be repeated here.

[0178] In some possible embodiments, the component information includes unit information carried by each of the multiple facets constituting the component, for example, the unit information carried by facet 1, facet 2, up to facet N, where N is greater than 2. The unit information can be a facet information, which includes: the position of the facet relative to the moving target reference point, the energy or amplitude corresponding to the facet, the material corresponding to the facet, the speed of the facet relative to the moving target reference point, the normal information of the facet, and the coordinates of multiple vertices of the facet. Taking a triangular face as an example, a triangular face includes three vertices and normal information, namely {x1, y1, z1}, {x2, y2, z2}, {x3, y3, z3}, and {x4, y4, z4}, where the first three points represent the three-dimensional coordinates of the point, and the last three-dimensional coordinate can be used to represent the normal information.

[0179] Based on the above technical solution, the information of the basic attributes and the information of the first information attributes are associated through a specific data format, and each information attribute in the first information attribute is optional. A variety of combinations of information attributes can be derived to enable the control node to obtain information of interest, and even obtain the information carried by each facet in the facets that constitute the moving target, thereby enabling the feedback information to more completely characterize the information of the moving target through a more effective representation method.

[0180] Figure 16 is a schematic diagram of another data format of feedback information proposed in an embodiment of the present application. The smallest feature unit of the perception data is a point used to constitute a moving target.

[0181] In some possible embodiments, compared with the data format described in the corresponding embodiment of FIG. 14 , the data format shown in FIG. 16 adds a quality factor corresponding to the unit information in the structural attributes, and the quality factor is used to indicate the reliability of the unit information.

[0182] In some possible embodiments, the second quality factor may include an error rate of the unit information and a confidence level of the unit information.

[0183] In some possible embodiments, when the minimum feature unit of the perception data is a facet used to constitute a moving target, a quality factor corresponding to the unit information may also be added to the unit information corresponding to each facet.

[0184] Based on the above technical solution, according to the needs of the first node, the feedback information can include the quality factor of the unit information corresponding to each minimum characteristic unit, thereby helping the first node to perform more accurate and reasonable perception analysis of the motion target based on the feedback information.

[0185] Figure 17 is a schematic diagram of another data format of feedback information proposed in an embodiment of the present application. The smallest feature unit of the perception data is a point used to constitute a moving target.

[0186] In some possible embodiments, compared to the data format described in the corresponding embodiment of Figure 14 , the data format shown in Figure 17 may include multiple identifiers for the moving target belonging to the identity attribute. This is because associating a moving target with multiple IDs facilitates the first node's subsequent differentiation between multiple moving targets with similar shapes and close proximity. For easier understanding, the following detailed description is provided in conjunction with Figure 3 .

[0187] Referring to Figure 3, assuming that at the current moment, two moving targets with similar shapes meet at a path intersection, and assuming that the current perception scene includes a second node 1, then based on the information at the current moment, even if the two moving targets are assigned their own IDs, the first node will not be able to distinguish between the two target objects later. However, in general, there may be multiple second nodes in a perception area. Assuming that the perception area also includes a second node 2, then in this scenario, the second node 1 can record all the IDs that may be associated with the two moving targets in their respective feedback information, for example: 1-1 and 1-2. Then, since the position of the second node 2 is usually different from that of the second node 1, the feedback information about the two moving targets that can be obtained from the perspective of the second node 2 is different from the feedback information determined by the second node 1. Finally, after the first node receives the feedback information from the second node 1 and the second node 2 respectively, based on the difference between the two feedback information, it is easy to distinguish the IDs corresponding to the two moving targets.

[0188] Based on the above technical solution, it is helpful for the first node to accurately identify multiple different moving targets with similar positions and shapes at the current moment.

[0189] Since the feedback information above consists of two parts, one part is required attributes and the other part is optional attributes, the required attributes can be the basic attributes mentioned above, and the optional attributes can be at least one of the quality attributes, identity attributes, or structure attributes mentioned above. Therefore, in the indication information, the optional attributes required by the first node can be referred to by the digitally encoded code values ​​shown in Table 3 below.

[0190] Table 3

[0191] The indication information sent by the first node may directly include the code value corresponding to the above basic attribute and the code value corresponding to at least one information attribute among the optional attributes.

[0192] When the code value corresponding to a certain optional information attribute is 1, it indicates that the first node needs the information belonging to the information attribute; when the code value corresponding to a certain optional information attribute is 0, it indicates that the first node does not need the information belonging to the information attribute.

[0193] For example, the indication information may be 1000, where 1 indicates that the first node requires basic attribute information, and the following three 0s indicate that the first node does not require optional attributes. The indication information may be 1100, indicating that the first node requires basic attribute information and quality attribute information, and does not require other optional attributes. However, in order to save signaling overhead for transmitting the indication information, the code values ​​corresponding to the basic attributes may be omitted.

[0194] In some possible embodiments, the above-mentioned indication information may also carry information specifically included in each information attribute. Taking the above-mentioned quality attribute as an example, the information included in the quality attribute may be referred to by a digitally encoded code value as shown in Table 4 below.

[0195] Table 4

[0196] Taking the above-mentioned identity attributes as an example, the information included in the identity attributes can be referred to by digitally encoded code values ​​as shown in Table 5 below.

[0197] Table 5

[0198] When the code value corresponding to the information included in a certain optional first quality factor is 1, it indicates that the first node needs the information; when the code value corresponding to the information included in a certain optional first quality factor is 0, it indicates that the first node does not need the information.

[0199] For example, in the above indication information, the field for indicating the first quality factor is 1101, indicating that the first node requires the angle resolution, distance resolution, and confidence level of the feedback information in the first quality factor.

[0200] In some possible embodiments, taking Tables 3, 4, and 4 above as examples, the information shown in these three tables can be interrelated to indicate which specific information in the optional information attributes the first node needs. The encoded fields included in the indication information sent by the first node are: 1-1100-1-10-0, where the connector "-" can be omitted in actual applications, but the number of code value bits corresponding to each reference information needs to be clarified in advance. Based on the above field examples, it can be seen that the above fields are used to indicate that the first node needs to feedback information including the following optional attributes: angular resolution and distance resolution in the quality attribute, and the type of moving target in the identity attribute.

[0201] In some possible embodiments, the second node may store an information attribute index table. Different index values ​​in the table correspond to different combinations of optional information attributes to determine the first information attribute. Based on this, the indication information need only carry the index value to instruct the second node to determine feedback information including the corresponding information attribute. Furthermore, the index table may only record frequently used combinations of optional information attributes, thereby reducing the implementation difficulty of the method and the storage space occupied by the index table.

[0202] For example, the above index table can be represented by the following Table 6.

[0203] Table 6

[0204] When the indication information includes an index value of 0, the first information attribute only needs to include an identity attribute. When the indication information includes an index value of 1, the first information attribute needs to include a quality attribute and an identity attribute, and so on. The scale of the above Table 6 can also be expanded to introduce a variety of optional information attribute combinations. The embodiments of the present application do not limit the specific combination of optional information attributes.

[0205] In some possible embodiments, the indication information from the first node may be received through a control channel.

[0206] In some possible embodiments, the feedback information may be sent to the first node via the PDSCH, PUSCH or Xn interface.

[0207] In some possible embodiments, when the second node is a base station and the first node is a terminal device, the second node may send feedback information to the first node via PDSCH; when the second node is a terminal device and the first node is a base station, the second node may send feedback information to the first node via PUSCH; when the first node and the second node are both base stations, the second node may send feedback information to the first node via the Xn interface.

[0208] Based on the above technical solution, this solution can be combined with the existing transmission protocol, that is, this solution can be implemented based on the existing transmission protocol and transmission channel to reduce the implementation difficulty of this solution and increase the feasibility of the solution.

[0209] Figure 18 is a schematic flow diagram of another information transmission method 1800 proposed in an embodiment of the present application. This method can be applied to a first node in a cellular communication network, which can be a control node in any of the aforementioned communication systems. Method 1800 is the actions of the peer communication node in method 1300, corresponding to the steps of method 1300.

[0210] S1810: Send indication information to the second node.

[0211] The indication information is used to indicate a first information attribute, the first information attribute includes at least one of a quality attribute, an identity attribute or a structure attribute, and the quality attribute information is used to indicate the reliability of the perception information determined by the second node through the perception signal.

[0212] S1820: Receive feedback information from the second node.

[0213] The feedback information carries information of basic attributes and information of first information attributes, and the information of basic attributes is used to determine the position and / or speed of the moving target.

[0214] It should be understood that the contents of S1810 and S1820 correspond to the contents of S1310 to S1330 described above. Therefore, for the embodiments of S1810 and S1820, reference can be made to the embodiments corresponding to S1310 to S1330 described above, and no further details will be given here.

[0215] Based on the above technical solution, not only are the information attributes used to characterize the moving target expanded, but the first node can also instruct the second node to select the required or interested first information attributes from the expanded information attributes through indication information, and then receive feedback information including information of the basic attributes and information of the first information attributes. Moreover, the feedback information can more completely characterize the information of the moving target through an effective representation method, while also avoiding sending information corresponding to the information attributes that the first node does not need or is not interested in in all the expanded information attributes to the first node, causing unnecessary transmission overhead.

[0216] In some possible embodiments, the indication information may be sent to the second node via a control channel.

[0217] In some possible embodiments, the feedback information from the second node is received via a PDSCH, a PUSCH, or an Xn interface.

[0218] Based on the above technical solution, this solution can be combined with the existing transmission protocol, that is, this solution can be implemented based on the existing transmission protocol and transmission channel to reduce the implementation difficulty of this solution and increase the feasibility of the solution.

[0219] In some possible embodiments, the indication information is further used to indicate periodic information, and the periodic information is associated with the first information attribute and / or the basic attribute, and the periodic information is used to instruct the second node to periodically send feedback information.

[0220] Based on this, an embodiment of the present application also proposes an information transmission mechanism based on timing cycle triggering.

[0221] Figure 19 is a flow chart of another information transmission method 1900 proposed in an embodiment of the present application. This method can be applied to the second node in the cellular communication network.

[0222] S1910: Receive indication information from the first node.

[0223] The indication information is used to indicate the first information attribute and period information, the first information attribute includes a quality attribute, an identity attribute or a structural attribute, and the period information includes a first period and a second period, wherein the first period is associated with the basic attribute, the quality attribute and the identity attribute, the second period is associated with the structural attribute, and the second period is greater than the first period.

[0224] It should be understood that the first information attribute indicated by the above indication information has the same meaning as the first information attribute described in the above method 1300 and the corresponding embodiment. Therefore, for the embodiment of the expansion of the first information attribute and the manner in which the indication information indicates the first information attribute, please refer to the above corresponding embodiment for details and will not be repeated here.

[0225] In some possible embodiments, since the basic attribute is a necessary attribute, the first period must be associated with the basic attribute. In addition, since the quality attribute and the identity attribute are optional attributes, in scenarios of other embodiments, the first period can be associated with at least one of the quality attribute and the identity attribute, or even not be associated.

[0226] It should be understood that the number of time periods included in the above-mentioned period information is not limited to two, and may also include more than three time periods.

[0227] S1920: From the moment the indication information is received, after the first period has elapsed, first feedback information is sent to the first node according to the perception signal and the indication information.

[0228] The first feedback information carries information about basic attributes, quality attributes, and identity attributes. Furthermore, the perception signal in this embodiment has the same meaning as the perception signal in method 1300 . For details about the perception signal, see the preceding embodiment and will not be repeated here.

[0229] S1930: After the second period has elapsed since the moment the indication information is received, second feedback information is sent to the first node according to the perception signal and the indication information.

[0230] The second feedback information carries information about structural attributes.

[0231] It should be understood that the first feedback information and the second feedback information are a specific representation of the feedback information described in the above embodiment.

[0232] It should be understood that for a moving target, the information update frequency of the structural attributes of the moving target is relatively low. For example, the component information used to characterize a truck in the structural attributes includes the roof, body, and wheels. These three pieces of information usually do not change, so the information does not need to be updated frequently, so it does not need to be frequently fed back to the first node. The update frequency of the basic attributes, quality attributes, and identity attributes of the moving target is relatively high. Taking the information of the basic attributes as an example, the position of the moving target changes continuously, so it is necessary to frequently feed back this information to the first node.

[0233] Based on the above technical solution, the indication information can also indicate the time period for the second node to send feedback information including different information attributes, and associate the first period with a shorter period with the basic attributes, quality attributes and identity attributes to indicate that the second node relatively frequently feeds back information on the basic attributes, quality attributes and identity attributes that are updated more quickly to the first node, and associate the second period with a longer period with information on the structural attributes to indicate that the second node relatively infrequently feeds back information on the structural attributes that are updated more slowly to the first node, thereby increasing the rationality of the second node's information feedback.

[0234] In some possible embodiments, after the second node receives the indication information indicating the first information attribute and periodic information, the second node periodically repeats S1920 and S1930, thereby periodically sending corresponding feedback information to the first node. Based on this solution, the first node only needs to send the indication information to the second node once to continuously instruct the second node to send feedback information. Therefore, the first node does not need to repeatedly send the same indication information indicating the information attribute to the first node to obtain the feedback information corresponding to the corresponding data format required by the first node, thereby reducing the signaling overhead generated by sending the indication information.

[0235] It should be understood that since the feedback information determined based on the cycle has the same data format as the feedback information described in the above embodiment, the information attributes that can be included in the feedback information in this embodiment are described in detail in the above corresponding embodiment and will not be repeated here.

[0236] In some possible embodiments, the indication information from the first node may be received through a control channel.

[0237] In some possible embodiments, the feedback information may be sent to the first node via the PDSCH, PUSCH or Xn interface.

[0238] Correspondingly, Figure 20 is a schematic flow diagram of another information transmission method 2000 proposed in an embodiment of the present application. This method can be applied to the first node described above in a cellular communication network. This method 2000 is the action of the opposite communication node of the method 1900 described above, and corresponds to the steps of the method 1900 described above.

[0239] S2010: Send indication information to the second node.

[0240] Among them, the indication information is used to indicate the first information attribute and period information, the first information attribute includes a quality attribute, an identity attribute or a structure attribute, and the period information includes a first period and a second period, wherein the first period is associated with the basic attribute, the quality attribute and the identity attribute, the second period is associated with the structure attribute, and the second period is greater than the first period.

[0241] S2020: Receive first feedback information and second feedback information from the second node.

[0242] Among them, the first feedback information is the feedback information sent by the second node to the first node based on the perception signal and the indication information from the moment the indication information is received, after the duration of the first cycle has passed. The first feedback information carries information on basic attributes, quality attributes, and identity attributes; the second feedback information is the feedback information sent by the second node to the first node based on the perception signal and the indication information from the moment the indication information is received, after the duration of the second cycle has passed.

[0243] It should be understood that since the feedback information determined based on the cycle has the same data format as the feedback information described in the above embodiment, the information attributes that can be included in the feedback information in this embodiment are described in detail in the above corresponding embodiment and will not be repeated here.

[0244] Based on the above technical solution, the first node only needs to send indication information that can indicate the preset time period information when necessary, so that within the preset time period, the first node does not need to repeatedly send the same indication information to the first node to obtain the feedback information corresponding to the corresponding data format required by the first node, thereby reducing the signaling overhead generated by sending the indication information.

[0245] Based on the above technical solution, the first node also instructs the second node, through indication information, on the time period for sending feedback information including different information attributes, and associates the time period with the corresponding information attribute. This allows the second node to be instructed to feedback information with the information attribute corresponding to the time period after a shorter time period for information with a higher update frequency, and to feedback information with the information attribute corresponding to the time period after a longer time period for information with a lower update frequency. This increases the rationality of the second node's information feedback.

[0246] In some possible embodiments, the indication information may be sent to the second node via a control channel.

[0247] In some possible embodiments, the feedback information from the second node may be received via the PDCCH.
