Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a sensing method, device and storage medium. Background Technology

[0002] In a communication system, access network equipment can transmit sensing signals and receive sensing signals (i.e., echo signals) scattered by the environment and the sensing target. The access network equipment can analyze the echo signals to obtain sensing data, and then transmit the sensing data to the sensing network element so that the sensing network element can obtain relevant information about the environment and the sensing target.

[0003] However, if the access network device receives an instruction message to enable the sensing function, the entire access network device will perform communication sensing. This results in a larger granularity of the devices performing communication sensing, making it impossible to achieve more refined communication sensing. Summary of the Invention

[0004] This application provides a sensing method, apparatus, and storage medium for achieving more refined communication sensing.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] In a first aspect, this application provides a sensing method applied to a main control board. The method includes: receiving sensing data from a target active antenna unit (AAU), wherein the number of target AAUs is positively correlated with sensing requirements, the sensing requirements are used to characterize the requirements of sensing services, and the sensing data are used to represent the sensing data of the target object; and sending the sensing data of the target AAUs to a sensing network element when the sensing data of the target AAUs meets the sensing requirements.

[0007] In one possible implementation, the target AAU is any one of the first AAU, the second AAU, and the third AAU; the first AAU is the AAU with the smallest distance to the sensing target object among the multiple AAUs of the target access network device to which the main control board belongs; the second AAU is each of the multiple AAUs of the first baseband board to which the first AAU belongs; and the third AAU is each of the multiple AAUs of the target access network device.

[0008] In one possible implementation, the method further includes: sending a perception trigger message to the target AAU, the perception trigger message being used to instruct the target AAU to start perceiving the target object.

[0009] In one possible implementation, sending a perception trigger message to the target AAU includes: sending a perception trigger message to a first AAU; or, if the perception data of the first AAU does not meet the perception requirements, sending a perception trigger message to a second AAU; or, if the perception data of the second AAU does not meet the perception requirements, sending a perception trigger message to a third AAU.

[0010] In one possible implementation, the perception requirements include perception range requirements and / or perception accuracy requirements.

[0011] In one possible implementation, sensing accuracy requires the configuration information of the demodulated reference signal DMRS to be reused.

[0012] In one possible implementation, if the perception accuracy of the target AAU's perception data meets the perception accuracy requirements, the perception data of the target AAU is sent to the perception network element. This includes: analyzing the perception data of the target AAU to obtain the perception accuracy and / or perception range of the target AAU's perception data; and sending the perception data of the target AAU to the perception network element if the perception accuracy and / or perception range of the target AAU's perception data meets the perception accuracy requirements and / or perception range requirements.

[0013] Secondly, this application provides a sensing device applied to a main control board. The device includes a communication unit and a processing unit. The processing unit is configured to instruct the communication unit to receive sensing data from a target active antenna unit (AAU). The number of target AAUs is positively correlated with the sensing requirements. The sensing requirements are used to characterize the requirements of the sensing service, and the sensing data is used to represent the sensing data of the target object. When the sensing data of the target AAUs meets the sensing requirements, the processing unit is further configured to instruct the communication unit to send the sensing data of the target AAUs to the sensing network element.

[0014] In one possible implementation, the target AAU is any one of the first AAU, the second AAU, and the third AAU; the first AAU is the AAU with the smallest distance to the sensing target object among the multiple AAUs of the target access network device to which the main control board belongs; the second AAU is each of the multiple AAUs of the first baseband board to which the first AAU belongs; and the third AAU is each of the multiple AAUs of the target access network device.

[0015] In one possible implementation, the processing unit is further configured to instruct the communication unit to send a perception trigger message to the target AAU, the perception trigger message being used to instruct the target AAU to activate perception and perceive the target object.

[0016] In one possible implementation, the processing unit is further configured to instruct the communication unit to send a sensing trigger message to the first AAU; or, if the sensing data of the first AAU does not meet the sensing requirements, the processing unit is further configured to instruct the communication unit to send a sensing trigger message to the second AAU; or, if the sensing data of the second AAU does not meet the sensing requirements, the processing unit is further configured to instruct the communication unit to send a sensing trigger message to the third AAU.

[0017] In one possible implementation, the perception requirements include perception range requirements and / or perception accuracy requirements.

[0018] In one possible implementation, sensing accuracy requires the configuration information of the demodulated reference signal DMRS to be reused.

[0019] In one possible implementation, the processing unit is further configured to analyze the sensing data of the target AAU to obtain the sensing accuracy and / or sensing range of the target AAU's sensing data; if the sensing accuracy and / or sensing range of the target AAU's sensing data meets the sensing accuracy requirements and / or sensing range requirements, the processing unit is further configured to instruct the communication unit to send the sensing data of the target AAU to the sensing network element.

[0020] Thirdly, this application provides a sensing device comprising: a processor and a communication interface; the communication interface and the processor are coupled, the processor being configured to run computer programs or instructions to implement the sensing method as described in the first aspect and any possible implementation thereof.

[0021] Fourthly, this application provides a computer-readable storage medium storing instructions that, when executed on a terminal, cause the terminal to perform the perception method as described in the first aspect and any possible implementation thereof.

[0022] Fifthly, this application provides a computer program product containing instructions that, when run on a sensing device, cause the sensing device to perform the sensing method as described in the first aspect and any possible implementation thereof.

[0023] In a sixth aspect, this application provides a chip including a processor and a communication interface coupled to the processor. The processor is used to run computer programs or instructions to implement the sensing method as described in the first aspect and any possible implementation thereof.

[0024] Specifically, the chip provided in this application also includes a memory for storing computer programs or instructions.

[0025] In the sensing method provided in this application, the main control board receives sensing data from the target AAU and, if the sensing data of the target AAU meets the sensing requirements, sends the target AAU's sensing data to the sensing network element. This achieves sensing at the AAU granularity. Since an access network device can include multiple AAUs, the granularity of the AAU is smaller than that of the access network device. Therefore, the main control board can control the target AAU for communication sensing to achieve more refined communication sensing. Furthermore, the main control board controls the number of target AAUs to be sensed based on the sensing requirements, thus achieving effective control over the target AAUs and further improving the refinement of communication sensing.

[0026] Furthermore, the main control board can send sensing data that meets the sensing requirements to the sensing network elements, rather than sending the raw sensing data obtained after sensing measurements. Since the raw sensing data has a larger data volume, while the sensing data that meets the sensing requirements has a smaller data volume, transmitting sensing data that meets the sensing requirements between the main control board and the sensing network elements can reduce the communication burden in the communication system, thereby improving the stability of the communication system.

[0040] The sensing method, apparatus, and storage medium provided in the embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0041] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0042] The terms "first" and "second," etc., used in the specification and drawings of this application are used to distinguish different objects or to distinguish different treatments of the same object, rather than to describe a specific order of objects.

[0043] Furthermore, the terms "comprising" and "having," and any variations thereof, used in the description of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include other steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0044] It should be noted that in the embodiments of this application, the words "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0045] In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0046] Communication-sensing integration technology, as an important technology in communication networks, enables the coexistence of communication and sensing functions—two independent functions—within the same system through signal joint design and / or hardware sharing. This greatly reuses the resources (e.g., frequency and site resources) of both communication and sensing functions within the communication system, improving resource utilization and eliminating the need to construct two separate communication systems, thus reducing construction costs. Furthermore, in scenarios where continuous sensing is not required, this communication-sensing integration technology can improve the availability of communication and sensing functions.

[0047] Figure 1 This diagram illustrates an integrated communication and sensing application scenario. In this scenario, access network devices can perform normal data transmission with terminal devices. For example, access network devices and terminal device #1 can transmit data via communication link #1, and access network devices and terminal device #2 can transmit data via communication link #2. Access network devices can also transmit multiple sensing signals. For instance, an access network device can transmit sensing signal #1, and after scattering by the environment or a sensing target, it can receive the echo signal #1 corresponding to sensing signal #1. The access network device can then analyze the echo signal #1 to obtain sensing data #1 and transmit this sensing data #1 to the sensing network element via communication link #1. Similarly, an access network device can transmit sensing signal #2, and after scattering by the environment or a sensing target, it can receive the echo signal #2 corresponding to sensing signal #2. The access network device can then analyze the echo signal #2 to obtain sensing data #2 and transmit this sensing data #2 to the sensing network element via communication link #2.

[0048] In addition, the access network equipment can also send multiple sensing signals, which, after being scattered by the environment or the sensing target, are received by the terminal equipment as multiple echo signals. The terminal equipment can also send multiple sensing signals, which, after being scattered by the environment or the sensing target, are received as multiple echo signals.

[0049] In a communication system, access network equipment can transmit sensing signals and receive sensing signals (i.e., echo signals) scattered by the environment and the sensing target. The access network equipment can analyze the echo signals to obtain sensing data, and then transmit the sensing data to the sensing network element so that the sensing network element can obtain relevant information about the environment and the sensing target.

[0050] However, if the access network device receives an instruction message to enable the sensing function, the entire access network device will perform communication sensing. This results in a large granularity of the devices performing communication sensing, making it impossible to achieve fine-grained communication sensing.

[0051] In addition, since the raw data volume of the aforementioned sensing data is generally large, transmitting such sensing data will place a significant communication burden on the communication system, thereby affecting the stability of the communication system.

[0052] In view of this, this application provides a sensing method in which the main control board receives sensing data from the target AAU and, if the sensing data of the target AAU meets the sensing requirements, sends the sensing data of the target AAU to the sensing network element. This achieves sensing at the AAU level. Since an access network device can include multiple AAUs, the granularity of the AAU is smaller than that of the access network device. Therefore, the main control board can control the target AAU to perform communication sensing, achieving more refined communication sensing. Furthermore, the main control board controls the number of target AAUs to be sensed based on the sensing requirements, thus achieving effective control over the target AAUs and further improving the refinement of communication sensing.

[0053] Furthermore, the main control board can send sensing data that meets the sensing requirements to the sensing network elements, rather than sending the raw sensing data obtained after sensing measurements. Since the raw sensing data has a larger data volume, while the sensing data that meets the sensing requirements has a smaller data volume, transmitting sensing data that meets the sensing requirements between the main control board and the sensing network elements can reduce the communication burden in the communication system, thereby improving the stability of the communication system.

[0054] The technical solutions provided in this application can be applied to various communication systems, such as New Radio (NR) communication systems using 5G, future evolution systems, or multiple communication convergence systems.

[0055] For example, Figure 2 The diagram shows a schematic representation of a communication system according to an embodiment of this application. The communication system may include a main control board 201, at least one target AAU 202, and a sensing network element 203. Figure 2 Only one main control board 201, eight AAUs 202, and one sensing network element 203 are shown.

[0056] The main control board 201 is used to receive sensing data from the target AAU 202 and, if the sensing data meets the sensing requirements, send the processed sensing data to the sensing network element 203.

[0057] The number of target AAU202 objects is positively correlated with the perception requirements. Perception data is used to represent the perception data of the target objects. Perception requirements are used to characterize the requirements of perception services.

[0058] One possible implementation is, such as Figure 3 As shown, the main control board 201 may include: an initial baseband board sensing data unit, a baseband board triggered sensing unit, a backplane triggered re-sensing unit, and a result reporting unit. The initial base station sensing data unit is used to send a sensing trigger message to the target AAU 202 and receive sensing data from the target AAU 202 when the target AAU 202 is the first AAU. The baseband board triggered re-sensing unit is used to send a sensing trigger message to the target AAU 202 and receive sensing data from the target AAU 202 when the target AAU 202 is the second AAU. The backplane triggered re-sensing unit is used to send a sensing trigger message to the target AAU 202 and receive sensing data from the target AAU 202 when the target AAU 202 is the third AAU. The result reporting unit is used to send the processed sensing data to the sensing network element 203 when the sensing data meets the sensing requirements.

[0059] Optionally, the main control board 201 may further include a sensing accuracy requirement extraction unit (also referred to as a sensing trigger signaling receiving unit) and an AAU coverage capability recording unit. The sensing accuracy requirement extraction unit is used to receive sensing requirements from the sensing network element 203. The AAU coverage capability recording unit is used to acquire and store information such as the identifier of each AAU in the multiple AAUs of the target access network device to which the main control board 201 belongs, the identifier of its baseband board, its planned location, and its planned coverage radius.

[0060] Optionally, the main control board 201 can be deployed on the backplane of the BBU (Building Baseband Unit) in the access network equipment.

[0061] It should be noted that the BBU can be used to provide external interfaces for connecting to transmission equipment, radio frequency modules, universal serial bus (USB) devices, external clock sources, local maintenance terminals (LMTs), and the U2020 network management system. It is also used to perform signal transmission functions, automatic software upgrade functions for access network equipment, clock reception functions, LMT maintenance functions, U2020 network management system maintenance functions, uplink and downlink data processing functions, signaling processing functions, resource management functions, and operation and maintenance functions, thereby realizing centralized management of the entire access network equipment.

[0062] The BBU may include a baseband board and a main control board 201. The baseband board connects to one or more AAUs or remote radio units (RRUs).

[0063] The baseband board is used to perform the processing of modulated and demodulated signals (e.g., encryption and decryption) and circuit control functions.

[0064] It should be noted that, typically, the baseband signal transmitted by the baseband board has a low frequency, resulting in a short transmission distance. To extend the transmission distance of the baseband signal, it is necessary to modulate the baseband signal into a radio frequency (RF) signal and then transmit the modulated RF signal.

[0065] The main control board 201 is used to provide signaling processing and resource management functions for the baseband board, and to control the baseband board.

[0066] In some examples, the signaling processing and resource management functions include at least one of the following: configuration management functions, device management functions, software management functions, performance monitoring functions, primary / standby switchover functions, alarm functions, logging functions, and operation and maintenance (O&M) functions. The above is merely an exemplary description of the signaling processing and resource management functions; these functions may also include other functions, and this application makes no limitations on them.

[0067] AAU or RRU is mainly used for transmitting and receiving radio frequency signals.

[0068] It should be noted that, Figure 2 This is just an example framework diagram. Figure 2 The number of nodes included and the names of the devices are unlimited, except for... Figure 2 In addition to the functional nodes shown, the communication system may also include other nodes, such as terminal devices, and this application does not impose any restrictions on this.

As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of this application are also applicable to similar technical problems.

[0070] In practical implementation, Figure 2 All the equipment in the middle can be adopted Figure 4 The shown composition structure, or including Figure 4 The components shown. Figure 4This is a schematic diagram illustrating the composition of a sensing device 40 provided in an embodiment of this application.

[0076] It should be noted that the memory 404 can exist independently of the processor 401, or it can be integrated with the processor 401. The memory 404 can be used to store instructions, program code, or some data, etc. The memory 404 can be located inside or outside the sensing device 40, without limitation.

[0081] In this embodiment of the application, the chip system may be composed of chips or may include chips and other discrete devices.

[0082] Furthermore, the actions, terms, etc., involved in the various embodiments of this application can be referenced interchangeably without limitation. The message names or parameter names in the messages exchanged between the various devices in the embodiments of this application are merely examples, and other names may be used in specific implementations without limitation.

[0083] The following is combined with Figure 2 The communication system shown describes the sensing method provided in the embodiments of this application. The actions, terminology, etc., involved in the various embodiments of this application can be referenced interchangeably without limitation. The message names or parameter names in the messages exchanged between devices in the embodiments of this application are merely examples; other names may be used in specific implementations without limitation. The actions involved in the various embodiments of this application are merely examples; other names may be used in specific implementations. For example, "included in" in the embodiments of this application can be replaced with "carried on" or "carried in," etc.

[0084] To address the problems existing in the prior art, embodiments of this application propose a sensing method to reduce the communication overhead associated with sensing functions in a communication system. For example... Figure 5 As shown, the method includes:

[0085] S501, the target AAU sends its sensing data to the main control board. Correspondingly, the main control board receives the sensing data from the target AAU.

[0086] The number of target AAUs is positively correlated with perception requirements. Perception requirements characterize the requirements of perception services. Perception data represents the perception data of the target object.

[0087] In some examples, the sensing data for the target object may include at least one of the following: the position of the target object, the length of the target object, the width of the target object, and the height of the target object. The above is merely an exemplary description of the sensing data for the target object, and the sensing data for the target object may also be other data (e.g., the distance between the target object and the target AAU), which is not limited in this application.

[0088] For example, Figure 6 This diagram illustrates an example of a target AAU sensing a target object. Figure 6 As shown, the target object is perceived as Figure 6Taking a car in the context of a target AAU, including AAU#1, AAU#2, and AAU#3, as an example, the perception data of AAU#1, AAU#2, and AAU#3 can be the perception data obtained by perceiving the car from different angles.

[0089] In one optional embodiment, the target AAU is any one of a first AAU, a second AAU, and a third AAU. The first AAU is the AAU with the smallest distance to the sensing target object among the multiple AAUs of the target access network device to which the main control board belongs. The second AAU is each of the multiple AAUs of the first baseband board to which the first AAU belongs. The third AAU is each of the multiple AAUs of the target access network device.

[0090] In one alternative embodiment, the sensing requirements include sensing range requirements and / or sensing accuracy requirements.

[0091] In one possible embodiment, sensing accuracy requires the configuration information of the demodulation reference signal (DMRS).

[0092] Optionally, the DMRS configuration information may include low-precision, medium-precision, and high-precision DMRS configuration information. Higher precision DMRS configuration information results in higher resource consumption by the DMRS. For example, ... Figure 7 As shown, low-precision DMRS occupies 24 resource blocks. Figure 8 As shown, medium-precision DMRS occupies 48 resource blocks. Figure 9 As shown, medium-precision DMRS occupies 72 resource blocks.

[0093] In some examples, the sensing accuracy requirement may include angular accuracy requirements and / or distance accuracy requirements. The above is merely an exemplary illustration of sensing accuracy requirements, and other requirements (e.g., velocity accuracy requirements) may also be included, which are not limited in this application.

[0094] The business type may include at least one of the following: map type, perceived aircraft type, and perceived vehicle type. The above is merely an exemplary description of the business type, and the business type may also include other requirements (e.g., perceived stationary object type), which is not limited in this application.

[0095] Optionally, prior to S501, the sensing network element can send a sense cell active signaling message to the main control board. Correspondingly, the main control board receives the sense cell active signaling message from the sensing network element and determines the sensing requirements from the information carried by the sense cell active signaling message.

[0096] For example, Table 1 provides an example of the aforementioned cell activation signaling. As shown in Table 1, the aforementioned cell activation signaling may include: message type, business identifier.

[0097] The signaling mechanism consists of three parts: business identity (business ID), sense type, and parameter. The type represents the name of the signaling message. The business ID identifies the sense service. The sense type represents the type of sense service. The parameter characterizes the sense requirements. Sense requirements (Csense) can include at least one of the following: sense range requirement (Crange) and sense accuracy requirement (Caccuracy).

[0098] Table 1

[0099] type sense cell active business ID i parameter Csense

[0100] Optionally, relevant information about the target object (e.g., the location of the target object) can also be carried in the aforementioned sensing cell activation signaling, so that the sensing network element can send the sensing requirements and relevant information about the target object to the main control board at the same time.

[0101] S502, the main control board determines whether the perception data of the target AAU meets the perception requirements.

[0102] As an optional implementation method (denoted as implementation method 1), the implementation process of the above S502 can be as follows: the main control board analyzes the sensing range and / or sensing accuracy of the sensing data of the target AAU, and compares the obtained sensing range and / or sensing accuracy with the sensing range requirements and / or sensing accuracy requirements.

[0103] As an alternative implementation (denoted as implementation method 2), the perception requirements may also include the service type of the perception service. In this case, the implementation process of S502 above may also be as follows: the main control board processes the perception data of the target AAU, obtains the perception results required for the service type, and analyzes the perception range and / or perception accuracy of the perception results. The main control board compares the analyzed perception range and / or perception accuracy with the perception range requirements and / or perception accuracy requirements.

[0104] For example, combining with implementation method 2 above, taking the above-mentioned business type as the sensing aircraft type as an example, the implementation process of S502 above can also be as follows: The main control board can determine the position and velocity of the sensing target object corresponding to the echo signal based on the path loss analysis results and / or Doppler analysis results included in the sensing data of the target AAU. The main control board can analyze the position and velocity of the sensing target object corresponding to all echo signals in the sensing data of the target AAU based on the above method, and draw the flight trajectory of the aircraft based on the position and velocity of the sensing target object. The main control board determines the flight trajectory drawn above as the sensing result required for the business type. The main control board can determine whether the range of the above sensing result is greater than or equal to the range recorded in the sensing range requirement. And / or, the main control board can determine whether the accuracy of the above sensing result is greater than or equal to the accuracy recorded in the sensing accuracy requirement.

[0105] If the perception data of the target AAU meets the perception requirements, the main control board executes S503.

[0106] S503, the main control board sends the sensing data of the target AAU to the sensing network element. Correspondingly, the sensing network element receives the sensing data of the target AAU from the main control board.

[0107] In one possible implementation, the above-mentioned S503 process can be as follows: the main control board sends a sense NR result transfer signaling to the sensing network element through the S1 interface. Correspondingly, the sensing network element receives the sense NR result transfer signaling from the main control board and determines the sensing data of the target AAU from the information carried by the sense NR result transfer signaling.

[0108] It should be noted that the sensing network element can be made capable of transmitting data between the sensing network element and the main control board by adding the capability of the S1 interface (e.g., sensing requirements, sensing data of the target AAU, etc.).

[0109] For example, Table 2 provides an example of the aforementioned New Radio Result Transfer Signalling. As shown in Table 2, the aforementioned New Radio Result Transfer Signalling may include: type, business ID, access network device identifier (NodeB identity, NodeB ID), sense type, sense result, and other parameters. NodeB ID is used to identify the access network device. Sense result is used to characterize the sense data of the target AAU. Other parameters are used to represent Crange and Caccuracy. The descriptions of type and business ID above can be found in the corresponding sections above and will not be repeated here.

[0110] Table 2

[0111]

[0112] Based on the above example, if Sense Type is map, then Crange is...<x,y> Given the range shown, with Accuracy as Si, the above sense NR result transfer signaling can be represented as shown in Table 3 below:

[0113] Table 3

[0114]

[0115] It is understandable that the main control board and the sensing network element transmit data obtained by integrating the sensing data of the target AAU that meets the sensing requirements. Compared with transmitting sensing data, this can reduce the amount of data transmitted through the interface, reduce the transmission pressure of the interface, reduce the communication overhead in the communication system, and thus ensure the stability of the communication system.

[0116] It should be noted that, Figure 5 The method shown requires modification of the main control board. Maintenance personnel can modify the main control board's data processing capabilities beforehand, enabling it to process the sensed data and determine whether the target AAU's sensed data meets the sensing requirements.

[0117] In the sensing method provided in this application, the main control board receives sensing data from the target AAU and, if the sensing data of the target AAU meets the sensing requirements, sends the target AAU's sensing data to the sensing network element. This achieves sensing at the AAU granularity. Since an access network device can include multiple AAUs, the granularity of the AAU is smaller than that of the access network device. Therefore, the main control board can control the target AAU for communication sensing to achieve more refined communication sensing. Furthermore, the main control board controls the number of target AAUs to be sensed based on the sensing requirements, thus achieving effective control over the target AAUs and further improving the refinement of communication sensing.

[0118] Furthermore, the main control board can send sensing data that meets the sensing requirements to the sensing network elements, rather than sending the raw sensing data obtained after sensing measurements. Since the raw sensing data has a larger data volume, while the sensing data that meets the sensing requirements has a smaller data volume, transmitting sensing data that meets the sensing requirements between the main control board and the sensing network elements can reduce the communication burden in the communication system, thereby improving the stability of the communication system.

[0119] Combination Figure 5 ,like Figure 10 As shown in the figure, this application provides a sensing method, which includes the following steps:

[0120] S1001, the main control board sends a perception trigger message to the target AAU. Correspondingly, the target AAU receives the perception trigger message from the main control board.

[0121] Among them, the perception trigger message is used to instruct the target AAU to start perceiving the target object.

[0122] For example, the target object to be sensed may include at least one of the following: a car, an airplane, a drone, or a building. The above is merely an exemplary description of the target object to be sensed, and the target object may also be other objects (e.g., a tree), and this application does not impose any limitations on this.

[0123] It should be noted that since the target AAU can be any of the first AAU, second AAU, or third AAU, the target AAU can be divided into the following three cases: Case 1: The target AAU is the first AAU. Case 2: The target AAU is the second AAU. Case 3: The target AAU is the third AAU. For example... Figure 11 As shown, the perception methods in the above three cases are explained in detail.

[0124] Case 1: The target AAU is the first AAU.

[0125] In this case, the sensing method provided in the embodiments of this application may include the following S1101.

[0126] S1101, the main control board sends a perception trigger message to the first AAU. Correspondingly, the first AAU receives the perception trigger message from the main control board.

[0127] Optionally, the descriptions of the perception trigger messages can be found in the corresponding sections above, and will not be repeated here.

[0128] In one possible implementation, the above-mentioned S1101 implementation process can be S11011 to S10112:

[0129] S11011 The main control board obtains the position of each AAU among the multiple AAUs of the target access network device to which the main control board belongs from its own AAU coverage capability recording unit, and determines the distance between each AAU and the target object based on the position of each AAU and the position of the perceived target object.

[0130] S11012. The main control board determines the AAU with the smallest distance from multiple AAUs as the first AAU and sends a perception trigger message to the first AAU.

[0131] For example, Table 4 shows the location information of three AAUs. As shown in Table 4, the three AAUs include: AAU1, AAU2, and AAU3. AAU1 belongs to baseband board 1, and the location of AAU1 is...<La1,Lo1> The baseband board to which AAU2 belongs is baseband board 1, and the position of AAU2 is...<La1,Lo1> The baseband board to which AAU3 belongs is baseband board 2, and the position of AAU3 is...<La2,Lo2> .

[0132] Table 4

[0133]

[0134]

[0135] Scenario 2: The target AAU is the second AAU.

[0136] In this case, the sensing method provided in the embodiments of this application may include the following S1102.

[0137] S1102. If the sensing data of the first AAU does not meet the sensing requirements, the main control board sends a sensing trigger message to the second AAU. Correspondingly, the second AAU receives the sensing trigger message from the main control board.

[0138] In one possible implementation, the above-mentioned S1102 process may include the following S11021 to S11024: S11021, the first AAU sends its sensing data to the main control board. Correspondingly, the main control board receives the sensing data from the first AAU.

[0139] In the above implementation, in case 2, the implementation process of S11021 can be as follows: The first AAU sends a first sense result signaling to the main control board. Correspondingly, the main control board receives the first sense result signaling from the first AAU and determines the sense data of the first AAU from the information carried by the first sense result signaling.

[0140] For example, Table 5 provides an example of the first sensing result signaling mentioned above. As shown in Table 5, the first sensing result signaling may include: type, business ID, sense type, sense result 1, and AAU1 identifier (AAU ID). Here, sense result 1 represents the sensing data of the first AAU. AAU1 ID identifies the first AAU. The terms type, business ID, and sense type can be understood by referring to the descriptions in the corresponding positions above, and will not be repeated here.

[0141] Table 5

[0142] type First sense result business ID i sense type X sense result1 Di AAU1 ID 1

[0143] S11022 The main control board can analyze the perception data of the first AAU in terms of perception range and / or perception accuracy to obtain the perception range and / or perception accuracy of the first AAU's perception data.

[0144] S11023. The main control board determines whether the sensing range of the sensing data of the first AAU meets the sensing range requirements, and / or whether the sensing accuracy of the sensing data of the first AAU meets the sensing accuracy requirements.

[0145] If the sensing range of the first AAU's sensing data does not meet the sensing range requirement, and / or the sensing accuracy of the first AAU's sensing data does not meet the sensing accuracy requirement, then the main control board executes S11024.

[0146] For example, if the sensing range of the first AAU's sensing data is 1800 square meters, and the sensing range requirement is 2000 square meters, then the main control board can determine that the sensing range of the first AAU's sensing data does not meet the sensing range requirement.

[0147] If the sensing accuracy of the first AAU's sensing data is kilometers, and the required accuracy is meters, then the main control board can determine that the sensing accuracy of the first AAU's sensing data does not meet the sensing accuracy requirements.

[0148] S11024. The main control board sends a perception trigger message to the second AAU. Correspondingly, the second AAU receives the perception trigger message from the main control board.

[0149] Optionally, the first AAU can send a sensing signal to the target object based on preset resources and receive echo signals (i.e., signals scattered by the sensing object in the environment). The first AAU analyzes each echo signal (e.g., feature analysis, path loss analysis, and Doppler analysis) to obtain the sensing data of the first AAU.

[0150] It should be noted that the preset resources can change during the sensing measurement process of the second AAU. For example, the preset resources mentioned above may be the first resource in the first time period and the second resource in the second time period. The amount of the second resource is greater than the amount of the first resource.

[0151] For example, the amount of the first resource can be set by the second AAU according to the actual situation. If the first resource is an initial resource for performing sensing measurements, the second AAU can set the amount of the first resource to 100. The amount of the first resource can also be other values ​​(e.g., 98), and this application does not impose any restrictions on this.

[0152] The resource quantity of the second resource can be set by the second AAU according to actual conditions. The second AAU can determine the resource quantity of the second resource based on the resource quantity of the first resource and a preset superposition value. For example, the target terminal device can set the resource quantity of the second resource to 110. The quantity of the second resource can also be other values ​​(e.g., 108), and this application does not impose any restrictions on this.

[0153] Understandably, if the sensing range and / or sensing accuracy requirements are high, the second AAU will need more resources for communication measurements to ensure that the sensing data meets the requirements. Therefore, the amount of preset resources will increase with the increase in sensing range and / or sensing accuracy requirements; in other words, the amount of preset resources is positively correlated with the sensing range and / or sensing accuracy requirements.

[0154] It should be noted that the maximum value of the preset resource amount is the maximum resource amount allocated by the second AAU for the sensing service. The maximum resource amount allocated by the second AAU for the sensing service can be set by the second AAU based on the available resources of the access network equipment and a preset ratio. For example, if the available resources of the second AAU are 100 and the preset ratio is 80%, then the second AAU can set the maximum resource amount allocated for the sensing service to 80. The maximum resource amount allocated for the sensing service can also be other values ​​(e.g., 98), and this application does not impose any restrictions on this.

[0155] In one alternative implementation, the main control board sends the sensing data of the first AAU to the sensing network element when the sensing range of the first AAU meets the sensing range requirement and / or the sensing accuracy of the first AAU meets the sensing accuracy requirement.

[0156] Scenario 3: The target AAU is the third AAU.

[0157] In this case, the sensing method provided in the embodiments of this application may include the following S1103.

[0158] S1103. If the sensing data of the second AAU does not meet the sensing requirements, the main control board sends a sensing trigger message to the third AAU. Correspondingly, the third AAU receives the sensing trigger message from the main control board.

[0159] In one possible implementation, the above-mentioned S1103 process may include the following S11031 to S11034: S11031, the second AAU sends its sensing data to the main control board. Correspondingly, the main control board receives the sensing data from the second AAU.

[0160] In the above implementation, in case 3, the implementation process of S11031 can be as follows: the second AAU sends a second sense result signaling to the main control board. Correspondingly, the main control board receives the second sense result signaling from the second AAU and determines the sense data of the second AAU from the information carried in the second sense result signaling.

[0161] For example, Table 6 provides an example of the second sensing result signaling described above. As shown in Table 6, the second sensing result signaling may include: type, business ID, sense type, sense result2, and AAU2 ID. Sense result2 represents the sensing data of the second AAU. AAU2 ID identifies the second AAU. The terms type, business ID, and sense type can be understood by referring to the descriptions in the corresponding sections above, and will not be repeated here.

[0162] Table 6

[0164] S11032. The main control board can analyze the perception data of the second AAU in terms of perception range and / or perception accuracy to obtain the perception range and / or perception accuracy of the second AAU's perception data.

[0165] S11033, The main control board determines whether the sensing range of the sensing data of the second AAU meets the sensing range requirements, and / or whether the sensing accuracy of the sensing data of the second AAU meets the sensing accuracy requirements.

[0166] If the sensing range of the second AAU's sensing data does not meet the sensing range requirement, and / or the sensing accuracy of the second AAU's sensing data does not meet the sensing accuracy requirement, then the main control board executes S11034.

[0167] S11034. The main control board sends a perception trigger message to the third AAU. Correspondingly, the third AAU receives the perception trigger message from the main control board.

[0168] Optionally, the second AAU can send sensing signals to the target object based on preset resources and receive echo signals (i.e., signals scattered by the sensing objects in the environment after the aforementioned sensing signals are received). The second AAU analyzes each echo signal (e.g., feature analysis, path loss analysis, and Doppler analysis) to obtain the sensing data of the second AAU.

[0169] It should be noted that the description of the preset resources can be understood by referring to the descriptions in the corresponding positions above, and will not be repeated here.

[0170] In one optional implementation, the main control board sends the sensing data of the second AAU to the sensing network element when the sensing range of the second AAU meets the sensing range requirement and / or the sensing accuracy of the second AAU meets the sensing accuracy requirement.

[0171] Optionally, after S1103, the sensing method provided in this application embodiment may further include the following S1104 to S1105.

[0172] S1104, the third AAU sends its sensing data to the main control board. Correspondingly, the main control board receives the sensing data from the third AAU.

[0173] In one possible implementation, the above-mentioned S1104 process can be as follows: the third AAU sends a last sense result signaling to the main control board. Correspondingly, the main control board receives the last sense result signaling from the third AAU and determines the sensing data of the third AAU from the information carried by the last sense result signaling.

[0174] For example, Table 7 provides an example of the final perception result signaling described above. As shown in Table 7, the final perception result signaling may include: type, business ID, sense type, sense result3, and AAU3 ID. Sense result3 represents the perception data of the third AAU. AAU3 ID identifies the third AAU. The terms type, business ID, and sense type can be understood by referring to the descriptions in the corresponding sections above; they will not be repeated here.

[0178] S1105, the main control board sends the sensing data of the third AAU to the sensing network element. Correspondingly, the sensing network element receives the sensing data from the main control board.

[0179] It should be noted that the main control board can send the third AAU's sensing data to the sensing network element when the sensing data of the third AAU meets the sensing requirements, and it can also send the third AAU's sensing data to the sensing network element when the sensing data of the third AAU does not meet the sensing requirements.

[0180] In the sensing method provided in this application, the main control board can send a sensing trigger message to the target AAU to instruct the target AAU to start sensing the target object, so that the target AAU can provide sensing data to the main control board, so that subsequent communication sensing at the AAU level can be completed.

[0181] For example, Figure 12 An example of a perception method is shown, such as Figure 12As shown, the method includes the following steps:

[0186] S1204. The first AAU sends its sensing data to the main control board via the first baseband board. Correspondingly, the main control board receives the sensing data from the first AAU via the first baseband board.

[0189] S1206. The sensing network element sends a sensing request to the main control board. Correspondingly, the main control board receives the sensing request from the sensing network element.

[0190] It should be noted that S1201 and S1206 above can be executed together. That is, the sensing network element can send the position of the target object and the sensing requirement to the main control board at the same time. Correspondingly, the main control board receives the position of the target object and the sensing requirement from the sensing network element.

[0191] S1207. The main control board determines whether the sensing data of the first AAU meets the sensing requirements.

[0192] If the sensing data of the first AAU meets the sensing requirements, the main control board executes S1208.
