Currently, when user equipment (UE) provides feedback on detection results, it does not consider whether the obtained results are needed by the base station; it provides feedback as long as there is a result, leading to a waste of resources. Therefore, how to reduce the overhead in the sensing process needs to be addressed. Summary of the Invention

[0178] Figure 1 This is a schematic diagram of the architecture of the communication system 1000 used in an embodiment of this application. Figure 1 As shown, the communication system includes a wireless access network 100 and a core network 200. Optionally, the communication system 1000 may also include an Internet 300. The wireless access network 100 may include at least one wireless access network device (such as...). Figure 1 110a and 110b in the above), may also include at least one terminal (such as Figure 1 (Referring to 120a-120j in the original text). Terminals connect wirelessly to the wireless access network (WLAN) equipment, which in turn connects to the core network via wireless or wired connections. The core network equipment and the WLAN equipment can be independent physical devices, or they can integrate the functions of the core network equipment and the logical functions of the WLAN equipment onto the same physical device. Alternatively, a single physical device can integrate some of the functions of both the core network equipment and the WLAN equipment. Terminals and WLAN equipment can be interconnected via wired or wireless connections. Figure 1 This is just an illustration; the communication system may also include other network devices, such as wireless repeaters and wireless backhaul devices. Figure 1 It is not shown in the middle.

[0179] Radio access network equipment can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation NodeB (gNB) in a 5G mobile communication system, a next-generation base station in a 6G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system; it can also be a module or unit that performs some of the functions of a base station, for example, it can be a central unit (CU) or a distributed unit (DU). Here, the CU performs the functions of the radio resource control protocol and the packet data convergence protocol (PDCP) of the base station, and can also perform the functions of the service data adaptation protocol (SDAP); the DU performs the functions of the radio link control layer and the medium access control (MAC) layer of the base station, and can also perform some or all of the physical layer functions. For specific descriptions of the above-mentioned protocol layers, please refer to the relevant technical specifications of the 3rd Generation Partnership Project (3GPP). Wireless access network equipment can be macro base stations (such as...) Figure 1 110a in the text), can also be a micro base station or an indoor station (such as... Figure 1 110b) in the text can also be a relay node or a donor node, etc. The embodiments of this application do not limit the specific technology or device form used in the wireless access network equipment. For ease of description, the following description uses a base station as an example of a wireless access network device.

[0180] A terminal device can be a device that provides voice / data to a user, such as a handheld device or vehicle-mounted device with wireless connectivity. Terminal devices may include user equipment, and are sometimes also called terminals, access stations, UE stations, remote stations, wireless communication equipment, or user facilities, etc.

[0181] For example, the terminal device may be a mobile phone, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a complete vehicle, a wireless communication module in a complete vehicle, a telematics box (T-Box), a roadside unit (RSU), a wireless terminal in autonomous driving, a wireless terminal device in the Internet of Things (IoT), a wireless terminal device in telemedicine, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, or a wireless terminal device in a smart home, etc., and the embodiments of this application are not limited thereto.

[0182] By way of example and not limitation, in this embodiment, the terminal device can also be a wearable device. Wearable devices, also known as wearable smart devices, are a general term for devices that utilize wearable technology to intelligently design and develop everyday wearables, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not merely hardware devices, but can also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include devices that are feature-rich, large in size, and can achieve complete or partial functions without relying on a smartphone, such as smartwatches or smart glasses, as well as devices that focus on a specific type of application function and require the use of other devices such as smartphones, such as various smart bracelets and smart jewelry for measuring vital signs.

[0183] Terminal devices can also be V2X devices, such as smart cars, digital cars, unmanned cars, driverless cars, pilotless cars, autonomous cars, pure electric vehicles (EVs), hybrid electric vehicles (HEVs), range-extended electric vehicles (REEVs), plug-in hybrid electric vehicles (PHEVs), new energy vehicles, and roadside units (RSUs). Terminal devices can also be devices used in device-to-device (D2D) communication, such as electricity meters and water meters.

[0184] Furthermore, in this embodiment, the terminal device can also be a terminal device in an IoT system. IoT is an important component of the future development of information technology. Its main technical feature is to connect objects to the network through communication technology, thereby realizing an intelligent network of human-machine interconnection and object-to-object interconnection.

[0185] The various terminal devices described above, if located in a vehicle (e.g., placed inside or installed inside a vehicle), can all be considered in-vehicle terminal devices, also known as on-board units (OBUs). The terminal device of this application can also be an in-vehicle module, in-vehicle component, in-vehicle chip, or in-vehicle unit built into a vehicle as one or more components or units. The vehicle can implement the methods of this application through the built-in in-vehicle module, in-vehicle component, in-vehicle chip, or in-vehicle unit.

[0186] Base stations and terminals can be fixed or mobile. They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can be deployed on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of the base stations and terminals.

[0187] The roles of base stations and terminals can be relative, for example, Figure 1The helicopter or drone 120i can be configured as a mobile base station. For terminals 120j accessing the wireless access network 100 via 120i, terminal 120i is a base station; however, for base station 110a, 120i is a terminal, meaning that 110a and 120i communicate via a wireless air interface protocol. Of course, 110a and 120i can also communicate via a base station-to-base station interface protocol; in this case, 120i is also a base station relative to 110a. Therefore, both base stations and terminals can be collectively referred to as communication devices. Figure 1 The 110a and 110b in the text can be referred to as communication devices with base station functions. Figure 1 The 120a-120j in the text can be referred to as communication devices with terminal functions.

[0188] Communication between base stations and terminals, between base stations, and between terminals can be conducted using licensed spectrum, unlicensed spectrum, or both simultaneously. Communication can be conducted using spectrum below 6 GHz, spectrum above 6 GHz, or both simultaneously. The embodiments of this application do not limit the spectrum resources used for wireless communication.

[0189] In the embodiments of this application, the functions of the base station can be executed by modules (such as chips) within the base station, or by a control subsystem that includes base station functions. This control subsystem, including base station functions, can be a control center in the aforementioned application scenarios such as smart grids, industrial control, intelligent transportation, and smart cities. Similarly, the functions of the terminal can be executed by modules (such as chips or modems) within the terminal, or by a device that includes terminal functions.

[0190] The technical solutions provided in this application can be applied to wireless communication between communication devices. Wireless communication between communication devices can include: wireless communication between network devices and terminals, wireless communication between network devices, and wireless communication between terminal devices. In this application, the term "wireless communication" can also be abbreviated as "communication," and the term "communication" can also be described as "data transmission," "information transmission," or "transmission."

[0191] It is understood that the names of the signaling signals in the embodiments of this application are merely examples and may have different names in different systems and scenarios. The embodiments of this application do not limit this.

[0192] To facilitate understanding of the embodiments of this application, the terms involved in the embodiments of this application will be briefly explained below.

[0193] 1. Perception

[0194] Perception is the process of collecting, processing, and generating perception results from data. For example, data can be used to determine the distance, shape, and type of surrounding obstacles, or to determine the breathing rate and heart rate of a monitored object. The collected data can be obtained through sensors or through wireless signals.

[0195] Both wireless sensing and wireless communication are based on electromagnetic wave theory. The transmitting end modulates the electromagnetic wave signal, enabling it to carry source information. During propagation, the electromagnetic wave signal is affected by the wireless environment, meaning it is influenced by the environment and can therefore also carry environmental information. The receiving end analyzes the electromagnetic wave signal to obtain not only the carried source information but also sensing information reflecting the characteristics of the propagation environment. In other words, electromagnetic waves inherently possess both communication and sensing capabilities, making ISAC (Integrated Communication and Sensing) possible. This can also be called Joint Communications and Sensing (JCAS) or simply Integrated Communication and Sensing. Compared to systems where sensing and communication are separated, ISAC offers several advantages, such as cost savings, reduced equipment size, lower power consumption, improved frequency efficiency, and reduced mutual interference between communication and sensing.

[0196] 2. Perceiving the Scene

[0197] Perception scenarios can be categorized into network device-based perception scenarios, network device and terminal device-based perception scenarios, and terminal device-based perception scenarios. For example, see [link to example]. Figure 2 The perception scenarios shown in (1) to (6).

[0198] Figure 2 This is a schematic diagram of a perception scenario according to an embodiment of this application. Example:

[0199] Figure 2 The perception scenario shown in (1) is a network device-based perception scenario, where the network device acts as both the sender and receiver of the perception signal. For example, when the perception signal 1 sent by the network device reaches the target object (e.g., a vehicle), the network device can receive the perception signal 2 after the perception signal 1 is reflected by the target object, and then process the perception signal 2 to obtain the perception result.

[0200] Figure 2The perception scenario shown in (2) is also a network device-based perception scenario, where one network device acts as the transmitter of the perception signal and the other network device acts as the receiver of the perception signal. For example, when perception signal 1 sent by network device A reaches the target object, perception signal 1 is reflected by the target object, and network device B can receive perception signal 2. Then, network device B can process perception signal 2 to obtain the perception result.

[0201] Figure 2 The perception scenario shown in (3) is a perception scenario based on network devices and terminal devices. The network device is the sender of the perception signal, and the terminal device is the receiver of the perception signal. For example, the perception signal 1 sent by the network device reaches the target object. After the perception signal 1 is reflected by the target object, the terminal device can receive the perception signal 2. Then the terminal device can process the perception signal 2 to obtain the perception result.

[0202] Figure 2 The perception scenario shown in (4) is also a perception scenario based on network devices and terminal devices. The terminal device is the sender of the perception signal, and the network device is the receiver of the perception signal. For example, the perception signal 1 sent by the terminal device reaches the target object. After the perception signal 1 is reflected by the target object, the network device can receive the perception signal 2. Then the network device can process the perception signal 2 to obtain the perception result.

[0203] Figure 2 The perception scenario shown in (5) is a perception scenario based on a terminal device, where the terminal device acts as both the sender and receiver of the perception signal. For example, when perception signal 1 sent by the terminal device reaches the target object, the terminal device can receive perception signal 2 after the target object reflects the perception signal 1. The terminal device can then process perception signal 2 to obtain the perception result.

[0204] Figure 2 The perception scenario shown in (6) is also a terminal device-based perception scenario, where one terminal device acts as the transmitter of the perception signal and the other terminal device acts as the receiver of the perception signal. For example, the perception signal 1 sent by terminal device a reaches the target object. After the perception signal 1 is reflected by the target object, terminal device b can receive the perception signal 2. Then, terminal device b can process the perception signal 2 to obtain the perception result.

[0205] The aforementioned sensing signal 2 can be understood as a reflected signal of sensing signal 1. Sensing signal 2 carries more information than sensing signal 1. For example, sensing signal 2 can carry source information and environmental information.

[0206] 3. Perception accuracy: This describes the error between the perceived result and the ideal, true result. Taking distance perception as an example, if the distance between the perceived target and the sensing device is obtained as 6 meters (m), while the actual distance between the perceived target and the sensing device is 5 meters, then the perception error is 1 meter, which is also called the perception accuracy of 1 meter for this perception.

[0207] 4. Resolution: Used to describe the minimum ability of a sensing device to distinguish two different targets. Taking distance sensing as an example, a distance resolution of 1m should be understood as follows: when the distance between two sensed targets is greater than or equal to 1m, the sensing device can distinguish between two targets; when the distance between two sensed targets is less than 1m, the sensing device cannot distinguish between two targets.

[0208] 5. RCS: Radar Cross Section, a parameter used to describe the shape, directionality, reflectivity, and geometric cross-sectional size of an object. The larger the RCS of an object, the stronger the echo signal obtained by the radar from that object.

[0209] In the current scenario of integrated communication and sensing, the sensing receiver feeds back the detection results to the base station. The sensing results may include information such as the speed, position, and radar cross-section (RCS) of the detected target. After receiving the detection results, the base station proceeds with further processing.

[0210] Taking the sensing detection process transmitted by the base station and received by the UE as an example: the base station transmits a sensing signal, and the UE obtains the sensing target result within its sensing range based on the echo signal of the sensing signal. For example... Figure 3 As shown, there are two targets within the UE's detection range: a moving car and a walking person. The UE can detect these two targets using its detection algorithm, and then detect their speed, position (distance and angle), and RCS (Radar Cross Section) information, which it then feeds back to the base station. The base station performs further operations based on the information fed back by the UE. However, the UE does not consider whether the results it provides are actually needed by the base station; it simply feeds back any result it receives. For example, when the UE detects both the car and the person, even if the base station only needs the car's detection results, the UE will feed back both the car and person's detection results, leading to a waste of resources.

[0211] In view of this, this application proposes a communication method that can reduce the overhead in the sensing process.

[0212] This communication method can be applied between network devices and terminal devices, between network devices, or between terminal devices; this application does not specifically limit its application. For example, when this communication method is applied to a sensing scenario, the sensing mode can be that network device A sends a sensing signal and network device A receives the sensing signal; or network device A sends a sensing signal and network device B receives the sensing signal; or network device A sends a sensing signal and a terminal device receives the sensing signal; or a terminal device sends a sensing signal and network device A receives the sensing signal. That is, the communication method provided in this application can be applied to communication scenarios, sensing scenarios, and scenarios integrating sensing and communication. In short, the communication method of this application can be applied to any sensing scenario.

[0213] The following example, using a transmitting device (i.e., the first device) and a receiving device (i.e., the second device) as the main implementers of this communication method, will illustrate the method. Figure 4 As shown, the method includes the following steps:

[0214] S410, the first device determines the first feature of the perceived target.

[0215] The characteristics of the perceived target can be one or more of the following: velocity, acceleration, position, shape, distance between the perceived target and the first device, angle of the perceived target relative to the first device, duration of motion, or RCS. This application does not limit the type of perceived target; the perceived target can be dynamic, such as a pedestrian, vehicle, or animal; or it can be static, such as a utility pole or an obstacle on the road.

[0216] For example, the first feature can be a single feature, such as the speed of the perceived target; the first feature can also be multiple features, such as the speed, shape, and RCS of the perceived target.

[0217] One possible approach is for the first device to determine the primary feature of the perceived target based on business needs. For example, the first device might determine, based on current business needs, that it is necessary to acquire the speed of the perceived target. Or, it might determine that further decisions need to be made based on the speed of the perceived target, and so on.

[0218] S420, the first device sends a first instruction message to the second device, and the second device receives the first instruction message.

[0219] The first indication information indicates the first feature of the perceived target.

[0220] For example, the first device can be a network device, and the second device can be a terminal device. The purpose of the network device sending the first instruction information to the terminal device is to inform the terminal device of the characteristics of the sensing target that the network device currently needs. In other words, the network device indicates to the terminal device the characteristics of the sensing target that the terminal device needs to report.

[0221] The first indication information can indicate the first feature of the perceived target in the following ways:

[0222] Method 1: Indicates a reference value for the first feature.

[0223] For example, the first indication information indicates a speed. The reference value for the speed indicated by the first indication information is 5 m / s. This reference value serves as a reference for the value of the first feature, or in other words, this reference value can be understood as a condition. For example, if the speed value is the same as this reference value, then the following steps, such as S440, can be executed. Here, the value of the first feature is the actual value of the first feature obtained by the second device through sensing. For example, if the first feature is speed, the value of the first feature is the speed value of the sensed target obtained by the second device through sensing the sensed target.

[0224] Specifically, the first indication information can be downlink information. For example, the first indication information can be downlink control information (DCI).

[0225] Method 2: Indicates the range of values ​​for the first feature.

[0226] The range of values ​​for the first feature can also be understood as a condition. For example, if the value of the first feature is within the range of values ​​for the first feature, then the following steps can be executed, such as S440.

[0227] An example using speed as the primary characteristic. The first indication information indicates that the speed ranges from 3 m / s to 5 m / s.

[0228] One possible approach is for the first device and the second device to communicate based on a common set of speed ranges. That is, the feature value range indicated by the first indication information belongs to a first range set, which includes at least one value range. This first range set can be predefined or configured. For example, the first device sends indication information A to the second device, and indication information A indicates the first range set. Alternatively, the second device sends indication information B to the first device, and indication information B indicates the first range set.

[0229] An example of this first range set: This first range set lists the speed ranges (in m / s) of several typical objects, such as cars (2-20 m / s), pedestrians (0.1-2 m / s), stationary buildings (0 m / s), and flying birds (14-30 m / s).

[0230] One possible implementation involves adding a field to the DCI to indicate the speed range as the first indication information. For example, this field contains 2 bits, as shown in Table 1, with different values ​​corresponding to different speed ranges in the set of speed ranges.

[0231] Table 1. Correspondence between the values ​​and meanings of the indication information

[0232] Value meaning 00 0m / s 01 0.1~2m / s 10 2~20m / s 11 14~30m / s

[0233] It should be understood that Table 1 is only an example of the correspondence between the values ​​and meanings of the indication information.

[0234] When the first device sends a first instruction message to the second device, the first instruction message indicates speed and has a value of 01, which means that the speed range is 0.1 to 2 m / s.

[0235] Another possible approach is that the first indication information indicates a change in the value range of the first feature. For example, the first indication information indicates a change in the value range of the first feature relative to a first range, where the first range is the range to which the value of the first feature belonged in the previous perception result. This previous perception result is the perception result preceding the first perception result. Alternatively, the first range may be predefined.

[0236] In other words, the first indication information indicates the change in the value range of the feature in the current perception relative to the value range of the feature in the previous perception. Put simply, the first device indicates to the second device whether the current value range of the feature needs to be changed and the target value range to be changed.

[0237] Compared to indicating the range of values ​​for the first feature in each perception, this implementation can further save the overhead of the first indication information, especially when the number of different perception targets increases and the number of elements in the first range set increases accordingly.

[0238] One possible implementation is that the first indication information is a field added to the DCI to indicate range changes. For example, this field contains 2 bits, and different values ​​of the field correspond to different range changes within the range set. An example using speed as the first feature is shown in Table 2.

[0239] Table 2 shows the correspondence between the values ​​and ranges of the indicated information.

[0240] Value meaning 00 Maintain current speed range 01 The speed range index is reduced by 1 compared to the current index. 10 The speed range index is increased by 1 compared to the existing index. 11 The speed range index is 2 times larger than the current index.

[0241] It should be understood that Table 2 is only an example of the correspondence between the values ​​and meanings of the information.

[0242] Here, the index represents the index in the set of the range of values ​​of the velocity indicated by the first device in the previous sensing. That is, the range of values ​​of at least one first feature in the first range set corresponds one-to-one with at least one index, and the at least one index is different from each other. The first indication information indicates the change value of the index corresponding to the range of values ​​of the first feature compared to the index corresponding to the first range.

[0243] For example, the first indication information includes two bits. Value A indicates that the value range of the first feature remains unchanged (or the index corresponding to the value range changes by 0). Value B indicates that the index corresponding to the value range of the first feature changes by a value of Q compared to the index corresponding to the first range; for example, Q can be -1. Value C indicates that the index corresponding to the value range of the first feature changes by a value of W compared to the index corresponding to the first range; for example, W can be +1. Value D indicates that the index corresponding to the value range of the first feature changes by a value of E compared to the index corresponding to the first range; for example, E can be +2. It should be understood that the values ​​of Q, W, D, and E mentioned above are only examples.

[0244] For example, the first range set is {{0m / s}, {0.1~2m / s}, {2~20m / s}, {14~30m / s}, {0~20m / s}}, where {0m / s} corresponds to index 1, {0.1~2m / s} corresponds to index 2, {2~20m / s} corresponds to index 3, {14~30m / s} corresponds to index 4, and {0~20m / s} corresponds to index 5. In the previous sensing, the first indication information indicated index 4, meaning the first device indicated the second device's speed range as {14~30m / s}. In this sensing, the first indication information is 01, meaning the speed range in this sensing is 1 less than the index {14~30m / s}, i.e., the index is 4-1=3. Furthermore, the speed range corresponding to index 3 is {2~20m / s}.

[0245] It should be understood that the above-mentioned speed ranges are merely examples, and the values ​​within these ranges may overlap. One possible implementation is to not distinguish between different objects, but only define speed ranges. For example, a stationary object with a speed of 0 m / s, a low-speed object with a speed of 0–2 m / s, a medium-speed object with a speed of 2 m / s–20 m / s, a high-speed object with a speed of 20–35 m / s, and an ultra-high-speed object with a speed exceeding 35 m / s. The preset speed range set would then be {0, {0–2 m / s}, {2–20 m / s}, {20–35 m / s}, {>35 m / s}}. In this way, there is no overlap between the speed ranges.

[0246] Another possible approach is that the first indication information indicates the maximum and minimum reference values ​​of the first feature, or the first indication information indicates the change of the maximum reference value of the first feature relative to a first reference value, and / or the change of the minimum reference value relative to a second reference value, where the first reference value is the maximum reference value corresponding to the first feature value in the previous perception result, and the second reference value is the minimum reference value corresponding to the first feature value in the previous perception result, and the previous perception result is the perception result preceding the first perception result. Alternatively, the first reference value and / or the second reference value may be predefined.

[0247] One possible implementation is that the maximum reference value of the first feature belongs to at least one maximum reference value, the minimum reference value of the first feature belongs to at least one minimum reference value, and at least one maximum reference value corresponds one-to-one with at least one index, and at least one minimum reference value corresponds one-to-one with at least one index. In this way, the first indication information can indicate the index corresponding to the maximum reference value of the first feature and the index corresponding to the minimum reference value of the first feature.

[0248] The following example uses distance as a first feature, where the distance is the distance between the first device and the perceived target. The first device and the second device use two sets: one set is the minimum reference value set of distance {0, 10, 100, 200, 500}, where the index corresponding to 0 is 1, the index corresponding to 10 is 2, the index corresponding to 100 is 3, the index corresponding to 200 is 4, and the index corresponding to 500 is 5.

[0249] A set is the maximum reference value set of distances {10, 100, 200, 500, 1000}, where the index of 10 is 1, the index of 100 is 2, the index of 200 is 3, the index of 500 is 4, and the index of 1000 is 5.

[0250] In one possible scenario, the first and second devices can predefine the correspondence between the order of indications and which sets they correspond to. For example, the first indication information may include two indices, with the first index representing a value in the set of minimum reference values ​​for distance, and the second index representing a value in the set of maximum reference values ​​for distance. For instance, if the first indication information indicates two indices, 2 and 3, it means that the minimum reference value is 10 and the maximum reference value is 200, meaning that the first indication information indicates a distance range of 10-200.

[0251] Another possible scenario is that the first indication information points to an index, and the minimum and maximum reference values ​​for the distance are the values ​​corresponding to that index in the sets of minimum and maximum reference values, respectively. For example, if the first indication information points to an index of 2, then the minimum reference value for the distance is 10, and the maximum reference value is 100, meaning the first indication information indicates that the distance range is between 10 and 100.

[0252] Of course, different sets of reference values ​​can also correspond to different identifiers or indices. The first indication information can include both the index of the reference value set and the index of the specific value. For example, the minimum reference value set corresponds to identifier A, the maximum reference value set corresponds to identifier B, and the first indication information indicates A, 1, which means that the minimum reference value is 0.

[0253] Another possible implementation is that the first indication information includes two bits, indicating the change of the maximum reference value of the first feature relative to a first reference value and the change of the minimum reference value relative to a second reference value, including:

[0254] The first value of the first indication information indicates that the maximum reference value of the first feature remains unchanged, and / or, the minimum reference value of the first feature remains unchanged.

[0255] The second value of the first indication information indicates that the maximum reference value of the first feature is the first value, where the first value is the reference value with the smallest absolute difference from the first reference value among the reference values ​​less than the first reference value, and / or, the second value of the first indication information indicates that the minimum reference value of the first feature is the second value, where the second value is the reference value with the smallest absolute difference from the second reference value among the reference values ​​canceling out of the second reference value.

[0256] The third value of the first indication information indicates that the maximum reference value of the first feature is the third value, which is the reference value with the smallest absolute difference from the first reference value among the reference values ​​greater than the first reference value, and / or, the third value of the first indication information indicates that the minimum reference value of the first feature is the fourth value, which is the reference value with the smallest absolute difference from the second reference value among the reference values ​​greater than the second reference value.

[0257] The fourth value of the first indication information indicates that the maximum reference value of the first feature is the fifth value, which is the second smallest reference value among the reference values ​​greater than the first reference value and the absolute value of the difference between the first reference value and the first reference value. And / or, the fourth value of the first indication information indicates that the minimum reference value of the first feature is the sixth value, which is the second smallest reference value among the reference values ​​greater than the second reference value and the absolute value of the difference between the second reference value and the second reference value.

[0258] For example, as shown in Tables 3 and 4.

[0259] Table 3 Example of fields indicating changes in maximum distance.

[0260] Value meaning 00 The maximum distance remains unchanged 01 Use the smaller first value to distance from the maximum value. 10 Use the larger first value to distance from the maximum value. 11 Use the larger second value to distance from the maximum value.

[0261] Table 4 Examples of Fields Indicating Changes in Minimum Distance Values

[0262] Value meaning 00 The minimum distance remains unchanged. 01 Use the smaller first value to get to the minimum distance. 10 Use the larger first value to get to the minimum value 11 Use the larger second value to reach the minimum value

[0263] In the table, the first smaller value for the minimum distance can be understood as the reference value with the smallest absolute difference from the second reference value among the reference values ​​that are less than the second reference value. The first larger value for the minimum distance can be understood as the reference value with the smallest absolute difference from the second reference value among the reference values ​​that are greater than the second reference value. The second larger value for the minimum distance can be understood as the reference value with the second smallest absolute difference from the second reference value among the reference values ​​that are greater than the second reference value.

[0264] For example, the minimum reference value set for distance is {0, 10, 100, 200, 500}. The second reference value is 100. In Table 4, if the first indication information indicates 01, it means that the minimum reference value used in this perception is 10; if the first indication information indicates 10, it means that the minimum reference value used in this perception is 200; if the first indication information indicates 11, it means that the minimum reference value used in this perception is 500.

[0265] For the maximum reference value set {10, 100, 200, 500, 1000}, the first reference value is 200. In Table 3, if the first indication information indicates 01, it indicates that the maximum reference value in this perception is 100; if the first indication information indicates 10, it indicates that the maximum reference value in this perception is 500; if the first indication information indicates 11, it indicates that the maximum reference value in this perception is 1000.

[0266] One possible scenario is that the first and second devices predefine the correspondence between the order of indications and which sets they correspond to. For example, the value of the first field represents the change in values ​​within the set of minimum reference values ​​for distance, and the value of the second field represents the change in values ​​within the set of maximum reference values ​​for distance. For instance, if the first indication information indicates 01, 10, it means that the smaller first value is used for the minimum reference value, and the larger first value is used for the maximum reference value.

[0267] Another possible scenario is that the first indication information specifies a value, where the minimum and maximum reference values ​​for distance are the changes in the reference values ​​corresponding to that value in the sets of minimum and maximum reference values, respectively. For example, if the first indication information indicates 01, it means that the smaller first value is used for both the minimum and maximum reference values ​​for distance.

[0268] Of course, different sets of reference values ​​can also correspond to different identifiers or indexes. The first indication information can include both the index of the reference value set and the specific field value. For example, the set of values ​​from the minimum value corresponds to index 1, and the set of values ​​from the maximum value corresponds to index 2. If the first indication information is 1,00, it means that the distance from the minimum value remains unchanged.

[0269] It should be understood that Tables 3 and 4 above are for illustrative purposes only.

[0270] Alternatively, when at least one maximum reference value corresponds one-to-one with at least one index, and at least one minimum reference value corresponds one-to-one with at least one index, the first indication information can also indicate changes in the index to indicate changes in specific values. As shown in Tables 5 and 6, the correspondence between the index changes of distances to the maximum and minimum values ​​and the values ​​of the first indication information is illustrated.

[0271] Table 5 Example of the field indicating the change in maximum distance.

[0272] Value meaning 00 The index of the maximum distance remains unchanged. 01 The maximum distance index is reduced by 1 compared to the currently used index. 10 The maximum distance index is increased by 1 compared to the current index. 11 The maximum distance index is 2 greater than the current index.

[0273] Table 6 Examples of fields indicating changes in minimum distance value

[0274] Value meaning 00 The index of the minimum distance remains unchanged. 01 The minimum distance index is reduced by 1 compared to the currently used index. 10 The minimum distance index is increased by 1 compared to the current index. 11 The minimum distance index is increased by 2 compared to the current index.

[0275] The existing indexes can be found in the above description and will not be repeated here.

[0276] For example, in the set of maximum reference values ​​{10, 100, 200, 500, 1000}, the index corresponding to 10 is 1, 100 is 2, 200 is 3, 500 is 4, and 1000 is 5. The current index for the maximum distance is 4, which is 500. In Table 5, the first indication information is 01, indicating that the index of the maximum distance is 1 less than the current index, meaning the index of the maximum distance is 3, and the corresponding maximum distance value is 200. The minimum distance is determined similarly.

[0277] It should be understood that the examples given above, which used speed and distance as the first features, can also be implemented using the same methods. Examples include the angle of the target relative to the first device, the acceleration of the target, and the RCS of the target. For instance, taking angle as an example, the correspondence between the changes in the maximum and minimum angle values ​​and the values ​​of the first indication information is shown in Tables 7 to 10.

[0278] Table 7 Example of fields indicating maximum angle change

[0279] Value meaning 00 The maximum angle remains unchanged. 01 The maximum angle is achieved by using the smaller of the first values. 10 The maximum angle value uses the larger of the first values. 11 Use the larger of the two maximum angle values.

[0280] Table 8 Example of fields indicating minimum angle value change

[0281] Value meaning 00 The minimum angle remains unchanged. 01 The minimum angle is achieved by using the smaller of the first values. 10 The minimum angle is achieved by using the larger of the first values. 11 Use the larger second value for the minimum angle.

[0282] When the maximum and minimum angle values ​​correspond to the indices respectively, as shown in Tables 9 and 10, the correspondence between the index changes of the maximum and minimum distance values ​​and the values ​​of the first indication information is shown.

[0283] Table 9 Example of fields indicating maximum angle change

[0284] Value meaning 00 The index of the maximum angle remains unchanged. 01 The maximum angle index is 1 less than the currently used index. 10 The maximum angle index is increased by 1 compared to the current index. 11 The maximum angle index is 2 greater than the current index.

[0285] Table 10 Example of the field indicating minimum angle value change

[0286] Value meaning 00 The index of the minimum angle remains unchanged. 01 The minimum angle index is reduced by 1 compared to the currently used index. 10 The minimum angle index is increased by 1 compared to the current index. 11 The minimum angle index is increased by 2 compared to the current index.

[0287] For specific instructions on how to indicate distance, please refer to the explanation of distance indication methods above, which will not be repeated here.

[0288] In the above example, the changes in the maximum and minimum reference values ​​are located in two different tables. The field values ​​corresponding to the changes in the maximum and minimum values ​​are the same. For example, in Table 9, the field value corresponding to the maximum angle index minus 1 of the current index is 01, and the field value corresponding to the minimum angle index minus 1 of the current index is also 01. This application is not limited to this; for example, the changes in the maximum and minimum reference values ​​may be located in the same table, but the field values ​​corresponding to the changes in the maximum and minimum values ​​may be different.

[0289] It should be understood that the numerical values ​​in the forms of this application, as well as the values ​​of the indicator fields and the meanings they represent, are for illustrative purposes only and not as limitations.

[0290] In other words, the tables in this application are merely examples, and no limitations are made on their content or format. Furthermore, the content of the tables can also be presented in other ways, such as formulas.

[0291] Another example, using RCS as the first feature. The correspondence between the values ​​of the first indication information and the range of RCS is shown in Table 11.

[0292] Table 11 Examples of RCS Range Indication Fields

[0293] Value <![CDATA[Meaning (m 2 )]]> 000 0.1±0.01 001 6±0.01 010 1±0.01 011 100±0.01 100 0.01±0.01 101 200±0.01 110 2±0.01 111 10±0.01

[0294] Optionally, the first indication information can also indicate changes in the RCS range. Table 12 shows the correspondence between the values ​​of the first indication information and changes in RCS.

[0295] Table 12 Examples of RCS Change Indication Fields

[0296] Value meaning 00 RCS range remains unchanged. 01 The RCS range index is reduced by 1 compared to the current index. 10 The RCS range index is increased by 1 compared to the current index. 11 The RCS range index is 2 times larger than the current index.

[0297] The first device can also directly indicate the range of RCS, for example, objects with an RCS range of {0~0.1}, objects with an RCS range of {0.1~5}, objects with an RCS range of {5~50}, objects with an RCS range of {50~200}, and objects with an RCS greater than 200. The preset RCS range set is then {{0~0.1}, {0.1~5}, {5~50}, {50~200}, {>200}}.

[0298] Examples of using acceleration as the first feature, and examples of the first indication information indicating the acceleration range, are shown in Table 13.

[0299] Table 13 Examples of Acceleration Range Indication Fields

[0300] Value meaning 00 0~0.5m / s2 01 0.5~3m / s2 10 >3m / s2 11 reserve

[0301] The meaning of the value 11 is reserved.

[0302] Another possible implementation is that the first indication information indicates a first threshold for a first feature. Furthermore, the first threshold belongs to at least one threshold, which can be configured or predefined.

[0303] Taking the motion duration of the perceived target as an example, the set of motion duration thresholds is {1s, 10s, 100s}. A field (first indication information) for indicating the motion duration threshold is added to the DCI. This field contains 2 bits, corresponding to four states, one of which is reserved, as shown in Table 14.

[0304] Table 14 Examples of motion duration threshold indication fields

[0305] Value meaning 00 1s 01 10s 10 100s 11 reserve

[0306] S430, the second device acquires the first perception result, which includes the feature information of the perceived target.

[0307] This step is optional.

[0308] The first perception result may include one or more feature information. For example, the second device performs perception on the target and obtains all the results that the target can be perceived. In this case, the order of S420 and S410 is not limited.

[0309] For example, the first perception result may include one or more of the following: the velocity, acceleration, position, shape, distance from the first device, angle relative to the first device, duration of motion, or RCS of the perceived target. The first perception result includes information about a first feature, such as the value of the first feature or information about the perceived target corresponding to the first feature, such as the acceleration, position, shape, distance from the first device, angle relative to the first device, duration of motion, or RCS of the perceived target, etc.

[0310] The first sensing result can also be obtained based on the first indication information. For example, if the first indication information indicates the range of speed values, then the second device performs sensing on the sensing target and obtains the speed information of the sensing target. In this case, S420 should follow S410.

[0311] S440, the second device determines information about the first feature from the first perception result based on the first instruction information.

[0312] When the second device acquires multiple feature information of the perceived target, it can filter the multiple feature information based on the first indication information to determine the information of the feature indicated by the first indication information (i.e., the first feature), or determine the information of the feature that conforms to the reference value or value range indicated by the first indication information.

[0313] The information of the first feature is used to characterize the perception result of the first feature and / or the perception target associated with the perception result. Specifically, the information of the first feature can be the value of the first feature, or the information of the perception target corresponding to the value of the first feature, such as the identity information of the perception target, for example, ID.

[0314] For example, when the first feature is velocity, the information of the first feature can be the velocity value sensed by the second device, such as 3 m / s. The information of the first feature can also be the information of the sensing target corresponding to the velocity value of 3 m / s, such as at least one of the following: the ID of the sensing target, the position of the sensing target, the type of the sensing target (e.g., judging the sensing target as a vehicle based on the velocity). The aforementioned first sensing result can include information of at least one feature of the sensing target, such as at least one feature being velocity, acceleration, motion duration, RCS, etc. For example, the first sensing result is a velocity of 3 m / s and an acceleration of 1 m / s². 2 The duration of the motion is 3 seconds, and the RCS is 2 meters. 2 .

[0315] Similarly, when the first feature is acceleration, the information of the first feature can be the value of the acceleration sensed by the second device, such as 1 m / s². 2 When the first feature is the duration of motion, the information of the first feature can be the value of the duration of motion sensed by the second device, such as 3 seconds. When the first feature is the RCS (Regional Cross Section), the information of the first feature can be the value of the RCS sensed by the second device, such as 2 meters. 2 When the first feature is the distance between the sensing target and the first device, the information of the first feature can be the value of the distance between the sensing target and the first device as perceived by the second device, such as 6m. When the first feature is the angle of the sensing target relative to the first device, the information of the first feature can be the value of the angle of the sensing target relative to the first device as perceived by the second device, such as 30°. The first sensing result can include the values ​​of each of the above first features. The information of the first feature can also be the information of the sensing target corresponding to each value of the first feature.

[0316] When multiple targets are sensed, the information of the first feature can be multiple reference values ​​or values ​​of the first feature that conform to the indication of the first indication information. Taking velocity as an example, the velocity value corresponding to target 1 is 1 m / s, the velocity value corresponding to target 2 is 3 m / s, and the velocity value corresponding to target 3 is 2.5 m / s. The first sensing result can include the sensing results of multiple targets, where the sensing result of each target can include information on features such as distance, angle, velocity, acceleration, RCS, duration of motion, shape, position, and type.

[0317] In the case of multiple sensing targets, the information of the first feature can also be the identity information of each sensing target, such as ID.

[0318] S450, the second device sends information about the first feature to the first device, and correspondingly, the second device receives the information about the first feature.

[0319] This step is optional.

[0320] One possible implementation is that the second device sends information about the first feature when it determines that the value of the first feature of the perceived target conforms to a reference value of the first feature (i.e., the value of the first feature is the reference value of the first feature indicated by the first indication information), or when the value of the first feature falls within the value range of the first feature (i.e., the value of the first feature belongs to the value range of the first feature indicated by the first indication information). Alternatively, the second device filters the acquired feature information; only when the value of the feature meets the criteria indicated by the first indication information is the second device fed back the feature information to the first device; otherwise, the second device does not feed back the feature information.

[0321] For example, if the first indication information specifies a reference speed range of 14–30 m / s, but the second device detects a speed of 7 m / s for the target, then the device will not report the speed characteristic of the target, or will not report any information about the target. If the second device detects a speed within the 14–30 m / s range, such as 19 m / s, then the second device will report the speed value to the first device, and / or report the corresponding target information to the first device.

[0322] The feedback method for other first features is similar. It should be noted that, regarding the method of indicating a threshold in the first indication information, if the feature of the perceived target detected by the second device does not reach the threshold indicated by the first indication information, no feedback is given; if the threshold is reached, the feature information, such as its value and / or information about the perceived target, is fed back. Taking motion duration as an example, if the first indication information indicates a first threshold of 10 seconds, and the second device obtains a motion duration of 9 seconds by sensing the perceived target, no feedback is given; if the speed of the perceived target is obtained as 16 seconds by sensing the perceived target, then the motion duration of the perceived target and / or other information about the perceived target are fed back to the first device.

[0323] When the range indicated by the first indication information changes, the second device can determine the changed feature value or feature value range indicated by the first indication information, and then determine whether to feed back the acquired feature information. Taking angle as the first feature as an example, the set of minimum angle values ​​is {90, -60, -30, 0, 30, 60}, and the set of maximum angle values ​​is {-60, -30, 0, 30, 60, 90}. Assume that the minimum angle value used by the second device in the last filtering of the perception results was 0, and the maximum angle value was 60 (i.e., the minimum and maximum angle values ​​used in the most recent perception). The first device indicates that the maximum angle value change indication field is 01 (corresponding to Table 9), and the minimum angle value change indication field is 01 (corresponding to Table 10). The second device sets (or updates, refreshes, or confirms) the minimum angle value to -30 based on the first indication information, while keeping the maximum angle value unchanged at 30. Furthermore, the second device filters angle feature information from the perception results with angles between -30 and 30 degrees and feeds it back to the first device.

[0324] Understandably, the second device determines whether to feed back feature information by judging whether it conforms to the value, value range, or threshold indicated by the first indication information. Furthermore, a certain allowable range, such as an error range, can be predefined or configured. For example, taking motion duration as an example, if the first indication information indicates a first threshold of 10s and an error range of 0.2s, and the second device obtains a motion duration of 9.9s from sensing the target, then it feeds back the information; if it obtains a velocity of 9.7s from sensing the target, then it does not feed back the motion duration of the target to the first device.

[0325] It should be understood that in this application, the first indication information includes one or more of the following: the velocity range or threshold to be satisfied by the desired sensing result; the RCS velocity range or threshold to be satisfied by the desired sensing result; the acceleration range or threshold to be satisfied by the desired sensing result; the motion duration threshold to be satisfied by the desired sensing result; the distance range or threshold to be satisfied by the desired sensing result; and the angle range or threshold to be satisfied by the desired sensing result. These parameters can be obtained directly or indirectly by the second device through processing the received signal.

[0326] In summary, after receiving the instruction information from the first device, the second device uses the corresponding parameter range to filter the sensing results. For speed, sensing results within the indicated range are reported; for RCS, sensing results within the indicated range are reported; for acceleration, the velocity value in the sensing result is differentiated to obtain the acceleration, and then sensing results within the indicated range are reported; for motion duration, sensing results with a duration greater than a threshold are reported; for distance, sensing results within the indicated range are reported; and for angle, sensing results within the indicated range are reported.

[0327] This method enables the second device to filter the sensing results by sending instruction information from the first device to the second device, and to provide feedback sensing detection results that meet the requirements of the first device, thereby improving the utilization rate of feedback resources.

[0328] It should be noted that in this application, when the first device sends the first indication information, it can first send the information to the DU through the CU when configuring via RRC signaling, and then the DU sends the information to the RU, and finally the information reaches the second device; if it is sent via DCI signaling, the first indication information is sent from the DU to the RU, and finally the information reaches the second device.

[0329] The various implementation methods described in this paper can be independent solutions or combinations based on their internal logic, and all of these solutions fall within the protection scope of this application.

[0330] In the embodiments provided above, the methods provided by the embodiments of this application have been described from the perspective of interaction between various devices. To implement the functions of the methods provided in the embodiments of this application, network devices or terminal devices may include hardware structures and / or software modules, implementing the above functions in the form of hardware structures, software modules, or a combination of hardware structures and software modules. Whether a particular function is executed in the form of hardware structures, software modules, or a combination of hardware structures and software modules depends on the specific application and design constraints of the technical solution.

[0331] The module division in this embodiment is illustrative and represents only one logical functional division; in actual implementation, other division methods may be used. Furthermore, the functional modules in the various embodiments of this application can be integrated into a single processor, exist as separate physical entities, or be integrated into a single module. The integrated modules described above can be implemented in hardware or as software functional modules.

[0332] Similar to the above concept, such as Figure 5 As shown, this application embodiment also provides an apparatus 500 for implementing the functions of the first apparatus (e.g., the first device) or the second apparatus (e.g., the second device) in the above method. For example, the apparatus can be a software module or a chip system. In this application embodiment, the chip system can be composed of chips or can include chips and other discrete devices. The apparatus 500 may include: a processing unit 510 and a communication unit 520.

[0333] In this embodiment of the application, the communication unit may also be called a transceiver unit, which may include a sending unit and / or a receiving unit, respectively used to perform the sending and receiving steps of the first device or the second device in the above method embodiment.

[0334] The following, combined with Figures 5 to 7 This application provides a detailed description of the communication device provided in its embodiments. It should be understood that the descriptions of the device embodiments correspond to the descriptions of the method embodiments; therefore, any content not described in detail here will be referred to the method embodiments above, and for the sake of brevity, will not be repeated here.

[0335] A communication unit can also be called a transceiver, transceiver device, or transceiver unit. A processing unit can also be called a processor, processing board, processing module, or processing device. Optionally, the device in communication unit 520 used to implement the receiving function can be considered a receiving unit, and the device in communication unit 520 used to implement the transmitting function can be considered a transmitting unit; that is, communication unit 520 includes a receiving unit and a transmitting unit. A communication unit can sometimes also be called a transceiver, transceiver unit, or interface circuit. A receiving unit can sometimes be called a receiver, receiver circuit, or receiving unit. A transmitting unit can sometimes be called a transmitter, transmitter, or transmitting circuit.

[0336] The communication device 500 performs the above embodiment. Figure 4 The function of the first device in the process shown is as follows:

[0337] The communication unit is used for sending and receiving information. For example, it can send first instruction information or receive information based on first characteristics.

[0338] A processing unit for determining a first feature, etc.

[0339] The communication device 500 performs the above embodiment. Figure 4 The function of the second device in any of the illustrated processes is as follows:

[0340] The processing unit is used to acquire a first perception result, which includes feature information of the perceived target and information on determining a first feature from the first perception result based on a first instruction.

[0341] A communication unit is used to send and receive information. For example, it is used to receive first instruction information or send information about a first characteristic.

[0342] The above is just an example. The processing unit 510 and the communication unit 520 can also perform other functions. For a more detailed description, please refer to [link / reference needed]. Figure 4 The descriptions of the method embodiments shown or other method embodiments are not repeated here.

[0343] As another possible product form, the first and second devices described in the embodiments of this application can be implemented using a general bus architecture. For ease of explanation, see [link to documentation]. Figure 6 , Figure 6 This is a schematic diagram of the structure of a communication device 600 provided in an embodiment of this application. The communication device 600 includes a processor 601 and a transceiver 602. The communication device 600 can be a first device, or a chip or chip system therein; or, the communication device 600 can be a second device, or a chip or module therein. Figure 6 Only the main components of the communication device 600 are shown. In addition to the processor 601 and transceiver 602, the communication device 600 may optionally further include a memory 603 and input / output devices (not shown).

[0344] Optionally, the processor 601 is mainly used to process communication protocols and communication data, control the entire communication device, execute software programs, and process the data of the software programs. The memory 603 is mainly used to store software programs and data. The transceiver 602 may include radio frequency (RF) circuitry and an antenna. The RF circuitry is mainly used for converting baseband signals to RF signals and processing RF signals. The antenna is mainly used for transmitting and receiving RF signals in the form of electromagnetic waves. Input / output devices, such as touchscreens, displays, and keyboards, are mainly used to receive user input data and output data to the user.

[0345] Optionally, the processor 601, transceiver 602, and memory 603 can be connected via a communication bus.

[0346] When the communication device is powered on, the processor 601 can read the software program in the memory 603, interpret and execute the instructions of the software program, and process the data of the software program. When data needs to be transmitted wirelessly, the processor 601 performs baseband processing on the data to be transmitted and outputs the baseband signal to the radio frequency (RF) circuit. The RF circuit then performs RF processing on the baseband signal and transmits the RF signal outward in the form of electromagnetic waves through the antenna. When data is sent to the communication device, the RF circuit receives the RF signal through the antenna, converts the RF signal into a baseband signal, and outputs the baseband signal to the processor 601. The processor 601 converts the baseband signal into data and processes the data.

[0347] In another implementation, the radio frequency circuitry and antenna can be set up independently of the processor performing baseband processing. For example, in a distributed scenario, the radio frequency circuitry and antenna can be arranged remotely, independent of the communication device.
