[0134] Example 3

[0135] This embodiment introduces the concept of opening up sensing capabilities, which means that SF will share sensing service information with third-party devices (other functions or third-party applications).

[0136] The sensing function receives sensing capability information reports from the managed TRPs, combines the information reported by all TRPs, produces sensing service information for the coverage area of ​​the sensing function, and makes it available to third-party applications. When the SF receives information about multiple sensing modes supported by the TRP, such as the sensing area, the SF can extract the intersection or union of different sensing modes from the information made available to third-party applications.

[0137] The sensing function exposes this sensing service information to third-party applications, including information from at least one or more sensing services. Each sensing service's information includes at least one of the following parameters: sensing service type; reference point location; grid shape; grid list; and QoS capabilities.

[0138] The perception service type uses an enumeration type to indicate the specific perception services supported, including but not limited to low-altitude services, road services, marine services, river services, and home services.

[0139] In one embodiment, the aforementioned sensing services can be further subdivided. Some potential classifications are listed below, but the final classification is not limited to these categories and may include more. For example, low-altitude services can be further subdivided into one or more of the following: low-altitude intrusion detection services, low-altitude trajectory tracking services, low-altitude collision avoidance services, flight path collision avoidance services, etc. Road services can be further subdivided into one or more of the following: vehicle flow information monitoring, pedestrian flow information monitoring, intelligent driving assistance, etc. Marine and river services can also be further subdivided into one or more of the following: no-navigation zone monitoring, vessel detection, etc. Home services can be further subdivided into home security, elderly care, motion monitoring, etc.

[0140] The grid shape is used to indicate the shape of the grid. The grid shape includes at least one of the following parameters: cuboid information; regular hexagonal prism information; regular triangular prism information; regular octagonal prism information.

[0141] The cuboid information includes the length, width, and height of the cuboid.

In one embodiment, when the height is 0, it represents a rectangle, a regular hexagon, a regular triangular prism, and a regular octagon, respectively.

[0142] A grid list includes one of the following parameters: grid identifier; grid center coordinates.

[0143] The grid center coordinates represent the center coordinates of the bottom polygon or the center coordinates of the corresponding grid shape.

[0144] Example 4

[0145] This embodiment describes the transmission of sensing measurement requests.

[0146] The sensing function sends a sensing measurement request to the TRP, triggering the TRP to perform sensing measurements. The sensing measurement request includes at least one of the following parameters: TRP identifier; TRP single-site mode information; TRP dual-site mode information; UE and TRP dual-site mode information.

[0147] Among them, the TRP single-site mode information is used to instruct the TRP to perform self-transmission and self-reception parameters, and includes at least one of the following parameters: sensing service; sensing identification indication; sensing identification type list; sensing QoS requirement information.

[0148] The sensing services are indicated by an enumeration type, which includes, but is not limited to, low-altitude services, road services, marine services, river services, and home services.

[0149] In one embodiment, the aforementioned sensing services can be further subdivided. Some potential classifications are listed below, but the final classification is not limited to these categories and may include more. For example, low-altitude services can be further subdivided into one or more of the following: low-altitude intrusion detection services, low-altitude trajectory tracking services, low-altitude collision avoidance services, flight path collision avoidance services, etc. Road services can be further subdivided into one or more of the following: vehicle flow information monitoring, pedestrian flow information monitoring, intelligent driving assistance, etc. Marine and river services can also be further subdivided into one or more of the following: no-navigation zone monitoring, vessel detection, etc. Home services can be further subdivided into home security, elderly care, motion monitoring, etc.

[0150] The perception identification indicator is used to indicate whether type identification of the perceived target is required. For example, setting this indicator to 1 indicates that the perceived target type needs to be identified; setting it to 0 indicates that the perceived target type does not need to be identified. Upon receiving this information, if the TRP indicates that the perceived target type needs to be identified, it must indicate the perceived target type in the reported perception data. If the indicator indicates that the perceived target type does not need to be identified, it will not report the perceived target type in the reported perception data.

[0151] The perception identification type list includes one or more types that need to be identified. In one embodiment, each type to be identified is indicated by one bit or more bits. Figure 9 This is a schematic diagram of the perception type indication method according to an embodiment of the present invention, exemplarily, such as... Figure 9 As shown, in Figure 9 The methods of indicating using 1 bit or multiple bits are shown respectively. Figure 9 (a) describes a method of 1-bit indication that uses several bits to indicate multiple types that need to be identified, with each bit indicating one type that needs to be identified. Figure 9 (b) describes the indication using multiple bits. Each value of these multiple bits corresponds to a type that needs to be identified. If a value is not used for indication, the detection type is reserved. When multiple types need to be detected simultaneously, the corresponding bits are set to 1, or multiple values ​​are carried. Figure 9 The value of (b) in the equation is expressed in ∑ base, but it can be defined in binary or other forms in a specific description.

[0152] When SF requires TRP to detect multiple sensing types simultaneously, it can carry the value corresponding to each sensing type or set the corresponding bit to 1. For example, after receiving this information, if TRP detects a corresponding sensing type, it needs to report the corresponding type in the measurement report.

[0153] Sensing QoS requirement information is used to indicate the QoS requirements for sensing measurements. Sensing QoS requirement information includes at least one of the following parameters: refresh rate list; sensing measurement signal quality; speed range; distance range; angle range; positioning accuracy; speed accuracy; distance accuracy; angle accuracy; object shape; object size; sensing target recognition indication.

[0154] Accuracy indicators refer to how close a measured value is to the true value. For example, speed accuracy refers to how close the measured speed is to the actual speed of the perceived target. For instance, a positioning accuracy indicator of 0.5m means that the error between the expected position of the perceived target and its actual position does not exceed 0.5m.

[0155] Range indicators refer to the range within which the perceived target needs to be located. For example, distance range refers to the distance range of the target being sensed and measured. Here, distance range refers to the distance range from the receiving end. For example, angle range includes azimuth and elevation angle ranges.

[0156] Object shape refers to the depiction of the shape of a perceived target, and the degree to which the perceived object shape closely resembles the actual object shape.

[0157] Object size refers to the description of the size of a perceived target, and the degree to which the perceived size of the object closely approximates the actual size of the object.

[0159] The TRP information sent in pairs is used to indicate information about one or more paired TRPs. The information of each paired TRP includes at least one of the following parameters: TRP ID; TRP location; TRP transmission resource configuration.

[0160] Example 5

[0161] This embodiment introduces the sensing measurement reporting of TRP.

[0162] TRP, based on SF's sensing measurement request, receives wireless signals and generates sensing data. The sensing data includes at least one of the following parameters: sensing target data; sensing feature data.

[0163] Sensing target data is data used to indicate the characteristics of sensing targets, including features of one or more sensing targets. Each sensing target's features must include at least one of the following parameters: sensing target type; sensing target location; sensing target velocity; sensing target reliability; sensing signal quality; and measurement time.

[0164] The target type is used to indicate the type of the target being perceived. Figure 10 This is a schematic diagram illustrating the target type indication according to an embodiment of the present invention. Figure 10 The text demonstrates how target types can be indicated using 1 bit and multiple bits, respectively.

[0165] Methods of indicating using 1 bit or more bits. Figure 10 (a) describes a method of 1-bit indication that uses several bits to indicate multiple types that need to be identified, with each bit indicating one type that needs to be identified. Figure 10 (b) describes the use of 8-bit indicators. Each 8-bit value corresponds to a type that needs to be identified. If a value is not used for indication, the detection type is reserved. When multiple types need to be detected simultaneously, the corresponding bit is set to 1, or multiple values ​​are carried. Figure 10 The value of (b) in the table is expressed in binary. However, other number systems or other forms can be used for specific descriptions.

[0166] The perceived target confidence level describes the reliability of the detected target. This value can range from 0 to 1. The closer the confidence level is to 1, the higher the confidence level. For example, a confidence level of 1 indicates that the target is definitely an unmanned aerial vehicle (UAV). This value can also range from 0 to 100. For example, a confidence level of 100 indicates that the target is definitely a pedestrian.

[0167] The perceived target location refers to the location of the perceived target. The perceived target location includes one of the following parameters: longitude; longitude error range; longitude confidence level; latitude; latitude error range; latitude confidence level; altitude; altitude error range; altitude confidence level.

[0168] Longitude, latitude, and altitude represent the longitude, latitude, and altitude values ​​of the perceived target in the global coordinate system, respectively.

[0169] Longitude error range, latitude error range, and altitude error range refer to the error range in longitude, latitude, and altitude, respectively.

[0170] Longitude confidence, latitude confidence, and altitude confidence refer to the confidence level of the known target entity's location within the shape description range for longitude, latitude, and altitude, respectively.

[0171] Sensing signal quality is used to indicate the signal quality corresponding to the sensing target, including one of the following parameters: signal-to-clutter ratio; signal power; noise power; clutter power.

[0172] The signal-to-clutter-plus-noise ratio (SCNR) is the ratio of signal power to the sum of noise power and clutter power. For example, the SCNR can be expressed by the following formula:

[0173] Among them, P signal P represents the power of the signal. clutter P represents the power of the clutter signal. noise This indicates the power of the noise.

[0174] Clutter signals refer to interference signals that are not the target signal. For example, when calculating clutter signal power, the power of the interfering clutter can be estimated by combining it with the Constant False Alarm Rate (CFAR). Clutter samples are taken from the same pulse or residence time, and from cells adjacent to the target cell in terms of spatial location, Doppler effect, or both spatial location and Doppler effect; these are used to estimate the power of the interfering clutter.

[0175] Sensing feature data is used to indicate parameters of multipath measurements. Measurement parameters for each path must include at least one of the following: RSRPP; time delay or distance; azimuth; elevation; X-axis coordinate; Y-axis coordinate; Z-axis coordinate; velocity.

[0176] In the above embodiments of the present invention, the same information parameters are included in different transmission information. For example, both the perception measurement request and the perception capability information include the single-site mode information of the TRP, the dual-site mode information of the TRP, and the dual-site mode information of the UE and the TRP. The single-site mode information of the TRP, the dual-site mode information of the TRP, and the dual-site mode information of the UE and the TRP are essentially the same type of information, all including multiple types of parameters. The only difference lies in the types of parameters for the perception measurement request sent from the SF to the TRP and the perception capability information sent from the TRP to the SF.

[0177] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the principles of the present invention should be included within the scope of protection of the present invention.
