Perception method, device, storage medium and program product

[0001] The present application claims priority to the Chinese patent application No. 202411244561.6, filed on September 5, 2024, and entitled "Perception method, device, storage medium and program product", the whole content of which is incorporated herein by reference. TECHNICAL FIELD

[0002] The present application relates to the technical field of sensing integration, and in particular to a perception method, device, storage medium and program product. BACKGROUND

[0003] For the evolution of future communication systems, sensing integration has become the industry consensus.

[0004] In sensing integration, there are specific requirements for the sending and receiving of sensing signals.

[0005] A base station includes a distributed unit (DU) and a radio unit (RU). The DU is responsible for generating digital signals and processing echo signals, and the RU is responsible for sending sensing signals and reporting echo signals. Therefore, to support sensing integration, both the DU and the RU need to have the capability of sensing integration, and the configuration of relevant parameters and the start-stop interaction of functions need to be done well.

[0006] Currently, the DU and the RU are generally provided by the same equipment manufacturer, and the interaction mechanism and interface between the two are self-defined by the manufacturer.

[0007] However, with the evolution of the future enhanced common public radio interface (eCPRI) fronthaul architecture, there may be scenarios where the DU and the RU do not come from the same equipment manufacturer. In this case, how to enable the base station to implement the function of sensing integration is a problem to be solved. SUMMARY

The terminal can be used in a dedicated network device or a general-purpose device. The embodiments of the present application do not limit the specific technology and specific device form of the terminal.

[0066] Optionally, the communication device can be configured to function as a base station. For example, a UE can function as a scheduling entity that provides sidelink signals between UEs in V2X, D2D, or P2P, etc. As shown in FIG. 1, the cellular phone 120a and the car 120b communicate with each other using sidelink signals. The cellular phone 120a and the smart home device 120e communicate without relaying the communication signals through the base station 110b.

[0067] Optionally, the wireless communication system is usually composed of cells, a base station provides management of the cell, and the base station provides communication services to a plurality of mobile stations in the cell. Among them, the base station includes a BBU and a RRU. The BBU and the RRU can be placed in different places, for example: the RRU is pulled away and placed in a high traffic area; the BBU is placed in the central machine room. The BBU and the RRU can also be placed in the same machine room. The BBU and the RRU can also be different components under one rack. Optionally, one cell can correspond to one carrier or component carrier.

[0068] It should be understood that the number and type of devices in the communication system shown in FIG. 1 are only illustrative, and the present application is not limited thereto. In actual applications, more terminal devices, more access network devices, and other network elements, such as core network devices and / or network elements for implementing artificial intelligence functions, can also be included in the communication system.

[0069] It can be understood that all or part of the functions implemented by one or more of the terminal device, the access network device, the core network device, or the network element for implementing artificial intelligence functions can be virtualized, that is, implemented by one or more of a special processor or a general processor and a corresponding software module. Among them, the terminal device and the access network device involve the interface of air interface transmission, and the transceiver function of the interface can be realized by hardware. The core network device, such as the operation administration and maintenance (OAM) network element, can be virtualized. Optionally, one or more functions of the virtualized terminal device, access network device, core network device, or network element for implementing artificial intelligence functions can be implemented by a cloud device, such as a cloud device in an over the top (OTT) system.

[0070] Protocol layer structure between access network device and terminal device:

[0071] The communication between the access network device and the terminal device follows a certain protocol layer structure. The protocol layer structure can include a control plane protocol layer structure and a user plane protocol layer structure. For example, the control plane protocol layer structure can include the functions of protocol layers such as a radio resource control (RRC) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, a medium access control (MAC) layer, and a physical layer. For example, the user plane protocol layer structure can include the functions of protocol layers such as a PDCP layer, an RLC layer, a MAC layer, and a physical layer, and in a possible implementation, a service data adaptation protocol (SDAP) layer can be further included above the PDCP layer.

[0072] Optionally, the protocol layer structure between the access network device and the terminal device can further include an artificial intelligence (AI) layer for transmitting AI function related data.

[0073] Taking the data transmission between the access network device and the terminal device as an example, the data transmission needs to pass through the user plane protocol layers such as the SDAP layer, the PDCP layer, the RLC layer, the MAC layer, and the physical layer. Among them, the SDAP layer, the PDCP layer, the RLC layer, the MAC layer, and the physical layer can also be collectively referred to as an access layer. According to the transmission direction of the data, each layer is divided into a sending part and a receiving part. Taking the following downlink data transmission as an example, the PDCP layer obtains data from the upper layer, transmits the data to the RLC layer and the MAC layer, generates a transport block by the MAC layer, and then performs wireless transmission through the physical layer. The data is encapsulated in each layer. For example, the data received by a layer from the upper layer of the layer is regarded as a service data unit (SDU) of the layer, and after encapsulation by the layer, becomes a protocol data unit (PDU), and is then transmitted to the next layer.

[0074] Exemplarily, the terminal device can also have an application layer and a non-access layer. The application layer can be used to provide services to the application program installed in the terminal device, for example, the downlink data received by the terminal device can be transmitted to the application layer in sequence by the physical layer, and then provided to the application program by the application layer; for another example, the application layer can obtain the data generated by the application program and transmit the data to the physical layer in sequence to send to other sensing devices. The non-access layer can be used to forward user data, for example, to forward the uplink data received from the application layer to the SDAP layer or to forward the downlink data received from the SDAP layer to the application layer.

[0075] Structure of the access network device:

[0076] As shown in FIG. 2, it is a schematic diagram of the connection relationship of network elements on the access network side. On the 5G access network side, one gNB can further include a CU and a DU. One CU can connect multiple DUs, but one DU can only connect one CU. The split of the CU and the DU can be according to the protocol stack split. One possible way is to deploy the RRC layer, the SDAP layer and the PDCP layer in the CU, and to deploy the RLC layer, the MAC layer and the PHY layer in the DU. The CU and the DU are connected through the F1 interface. The CU represents the gNB and is connected to the core network through the NG interface. The CU represents the gNB and is connected to other gNBs through the Xn interface.

[0077] It can be understood that the above-mentioned processing functions of the CU and the DU according to the protocol layer division are only an example, and can also be divided in other ways, for example, the CU or the DU can be divided into functions with more protocol layers, and for another example, the CU or the DU can also be divided into partial processing functions with protocol layers. In one design, part of the functions of the RLC layer and the functions of the protocol layers above the RLC layer are arranged in the CU, and the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer are arranged in the DU. In another design, the functions of the CU or the DU can also be divided according to the service type or other system requirements, for example, according to the delay, the functions that need to meet the delay requirement are arranged in the DU, and the functions that do not need to meet the delay requirement are arranged in the CU. In another design, the CU can also have one or more functions of the core network. Exemplarily, the CU can be arranged on the network side for centralized management.

[0078] In the actual deployment of the base station, in addition to the logical gNB composed of the CU and the DU, the base station also includes the RU. The RU is a hardware unit containing part of the PHY layer function and the antenna, and it is connected to the DU through the front haul (FH) interface. Similarly, one DU can connect multiple RUs, but one RU can only connect one DU. The signaling forwarding among the RU, the DU and the CU is carried out according to the fixed connection relationship.

[0079] The RAN node can support one or more types of fronthaul interfaces, respectively corresponding to DUs and RUs with different functionalities. If the fronthaul interface between the DU and the RU is common public radio interface (CPRI), the DU is configured to implement one or more of baseband functions, and the RU is configured to implement one or more of radio frequency functions. If the fronthaul interface between the DU and the RU is another interface, which, relative to CPRI, moves one or more of the partial baseband functions for downlink, such as precoding, digital beamforming (BF), or inverse fast Fourier transform (IFFT) / add cyclic prefix (CP), from the DU to the RU for implementation, or one or more of the partial baseband functions for uplink, such as digital beamforming (BF), or fast Fourier transform (FFT) / CP removal, from the DU to the RU for implementation. In a possible implementation, the interface can be enhanced common public radio interface (eCPRI). Under the eCPRI architecture, the split between the DU and the RU is different, corresponding to different categories (Cat) of eCPRI, such as eCPRI Cat A, B, C, D, E, F.

[0080] Taking eCPRI Cat A as an example, for downlink transmission, with layer mapping as the cut, the DU is configured to implement layer mapping and one or more functions (i.e., one or more of encoding, rate matching, scrambling, modulation, layer mapping) before layer mapping, and other functions (e.g., one or more of RE mapping, digital beamforming (BF), or inverse fast Fourier transform (IFFT) / adding cyclic prefix (CP)) after layer mapping are implemented in the RU. For uplink transmission, with de-RE mapping as the cut, the DU is configured to implement de-mapping and one or more functions (i.e., one or more of decoding, de-rate matching, de-scrambling, de-modulation, inverse discrete Fourier transform (IDFT), channel equalization, de-RE mapping) before de-mapping, and other functions (e.g., one or more of digital BF or FFT / CP removal) after de-mapping are implemented in the RU. It can be understood that the function description of the DU and the RU corresponding to various types of eCPRI can refer to the eCPRI protocol, and will not be described here.

[0081] Optionally, any of the above DU, CU and RU can be a software module, a hardware structure, or a software module + hardware structure, without limitation. The existence form of different entities can be different, without limitation. For example, the DU and the CU are software modules, and the RU is a hardware structure. These modules and the methods executed thereby are also within the protection scope of the present application.

[0082] In the present application, "sending information" can be understood as one device sending information to another device, or can also be understood as one logical module sending information to another logical module in the device. For example, "RU sending information" can be understood as the RU sending information to another device (such as a DU), or can be understood as a logical module 1 in the RU sending information to a logical module 2 in the RU.

[0083] In the present application, "receiving information" can be understood as one device receiving information from another device, or can also be understood as one logical module receiving information from another logical module in the device. For example, "RU receiving information" can be understood as the RU receiving information from another device (such as a terminal), or can be understood as a logical module 1 in the RU receiving information from a logical module 2 in the RU.

[0084] In this application, "sending information to (for example, DU)" or related illustrations in the drawings can be understood as the destination of the information is DU. It can include direct or indirect sending information to DU. "Receiving information from (for example, DU)" or "receiving information from (for example, DU)" or "receiving information sent by (for example, DU)", or related illustrations in the drawings can be understood as the source of the information is DU, which can include direct or indirect receiving information from DU. The information between the source and the destination of the information sending may be processed as necessary, such as format change, etc., but the destination can understand the effective information from the source. Similar expressions in this application can be similarly understood, and will not be repeated here.

[0085] This application relates to the integration of sensing and communication. Among them:

[0086] In the communication scenario, the downlink signal sent by the network equipment is received and demodulated by the terminal; the network equipment receives the uplink signal sent by the UE.

[0087] The sensing scenario is different, and the sending and receiving principles are as follows:

[0088] Sensing sending: it is necessary to send specific sensing signals at specific time and frequency domain positions, using specific sending channels, selecting specific sending beams and specific transmission power.

[0089] Sensing receiving: it is necessary to receive and process the sensing signal reflection echo according to the sending side information at the corresponding time and frequency domain positions, using specific receiving channels and selecting specific receiving beams.

[0090] Supporting the integration of sensing and communication depends on the ability of DU and RU to integrate sensing and communication, and the configuration of related parameters and the start-stop interaction of functions.

[0091] At present, DU and RU are generally provided by the same equipment manufacturer, and the interaction mechanism and interface between them are self-defined by the manufacturer.

[0092] However, with the evolution of future eCPRI fronthaul architecture, there may be scenarios where DU and RU do not come from the same equipment manufacturer. In this case, how to enable the base station to realize the integration of sensing and communication function is a problem to be solved.

[0093] Therefore, the application provides a sensing scheme. The RU sends first information to the DU, the first information indicating capability information of the RU, the capability information of the RU including sensing capability. The DU determines first sensing parameters and second sensing parameters according to the first information, the first sensing parameters being used for configuring a sensing signal, and the second sensing parameters being used for configuring a back echo signal. The DU sends second information to the RU, the second information indicating the first sensing parameters and the second sensing parameters. The RU sends the sensing signal based on the first sensing parameters. And the RU sends the back echo signal to the DU based on the second sensing parameters. By using the scheme of the application, the DU can configure the sensing parameters based on the capability information of the RU by receiving the capability information of the RU, so that the sensing task is completed by the DU and the RU together.

[0094] Based on the above communication system, the sensing method provided by the application is described as follows:

[0095] As shown in FIG. 3, it is a flowchart of a sensing method provided by an embodiment of the application. The method can include the following steps:

[0096] S301. The RU sends first information to the DU.

[0097] Correspondingly, the DU receives the first information.

[0098] The first information indicates capability information of the RU. The capability information of the RU includes sensing capability, i.e. the capability of whether the RU supports sensing. For example, the first information can include 1 bit. When the value of the 1 bit is a first value, it indicates that sensing is supported. When the value of the 1 bit is a second value, it indicates that sensing is not supported.

[0099] Further, the capability information of the RU further includes at least one of the following: time domain information, bandwidth information, channel information, beam information, power information, format, scanning angle, horizontal distance, vertical distance, sensing speed resolution, angle resolution of the sensing signal, time domain information, bandwidth information, channel information, beam information, power information of the back echo signal.

[0100] The time domain information corresponding to the perception signal indicates time domain positions at which the RU can send the perception signal. The time domain information corresponding to the echo signal indicates time domain positions at which the RU sends the echo signal. The unit of the time domain can be a frame, a subframe, a slot, or a symbol. Correspondingly, the time domain information can be a frame number, a subframe number, a slot number, or a symbol number. In one example, in the integrated sensing and communication scenario, the network-configured time domain resources are used for communication (even mainly for communication) in addition to sensing, and the RU report can send the perception signal or the echo signal at a specific time domain position or positions configured by the network; in another example, the RU report can send the perception signal or the echo signal at all time domain positions configured by the network, for example, in the integrated sensing and communication scenario, the priority of sensing is higher, and therefore all time domain resources configured by the network can be used for sensing.

[0101] The bandwidth information corresponding to the perception signal indicates frequency domain start positions and end positions at which the RU can send the perception signal. The bandwidth information corresponding to the echo signal indicates frequency domain start positions and end positions at which the RU sends the echo signal. The unit of the bandwidth (or the frequency domain) can be a subcarrier, a resource block (RB), or a resource element (RE). Correspondingly, the bandwidth information can be a subcarrier index, an RB index, or an RE index. In one example, in the integrated sensing and communication scenario, the network-configured bandwidth resources are used for communication (even mainly for communication) in addition to sensing, and the RU report can send the perception signal or the echo signal at a certain frequency domain position or positions configured by the network; in another example, the RU report can send the perception signal or the echo signal at all frequency domain positions configured by the network, for example, in the integrated sensing and communication scenario, the priority of sensing is higher, and therefore all frequency domain resources configured by the network can be used for sensing.

[0102] The channel information corresponding to the perception signal indicates which channel number combination or channel number bitmap the RU can use to send the perception signal. The channel information corresponding to the echo signal indicates which channel number combination or channel number bitmap the RU can use to send the echo signal. The channel can be replaced by a channel, and the like. The channel number bitmap refers to that, assuming there are N channels, the channel number bitmap includes N bits, and each bit in the N bits indicates whether the corresponding channel can send the perception signal or the echo signal, where N is a positive integer. In one example, in the integrated sensing and communication scenario, the network configures the channels to be used for communication (even mainly for communication) in addition to sensing, and the RU reports that it can send the perception signal or the echo signal on some specific channels configured by the network; in another example, the RU reports that it can send the perception signal or the echo signal on all channels configured by the network, for example, in the integrated sensing and communication scenario, the priority of sensing is high, and therefore all channels configured by the network can be used for sensing.

[0103] The beam information (or beam scanning information) corresponding to the perception signal / echo signal includes the number of beams supported by the RU, the beam pointing direction, the beam accuracy, and the like. For example, the RU supports m beams for sending the perception signal / echo signal, each beam has a pointing direction (d1, d2, …, d m ), and each beam has a 3db beam width (w1, w2, …, w m ). For another example, the RU can indicate that the set of beams for sending the perception signal / echo signal can be the same as the beam signals used by the traffic in the communication cell.

[0104] The power information corresponding to the perception signal / echo signal indicates the power range supported by the RU for sending the perception signal / echo signal. For example, the RU can indicate that the power range supported for sending the perception signal / echo signal is P min ~ P max . For another example, the RU can indicate that the power range supported for sending the perception signal / echo signal is the same as the power range used by the traffic in the communication cell.

[0105] In addition, for the transmission of the perception signal, the RU can also indicate the format of the perception signal, the scanning angle, the horizontal distance, the vertical distance, the perception speed resolution, the angle resolution, and the like. According to different scenarios, the reported capabilities of the RU can be different.

[0106] S302. The DU determines the first perception parameter and the second perception parameter according to the first information.

[0107] After receiving the first information, the DU determines the first sensing parameter and the second sensing parameter according to the first information. The first sensing parameter is used to configure the sensing signal, and the second sensing parameter is used to configure the echo signal. Specifically, the DU determines the first sensing parameter according to the capability information of the RU for transmitting the sensing signal, and determines the second sensing parameter according to the capability information of the RU for transmitting the echo signal. The first sensing parameter determined by the DU can be a subset or a full set of the capability information of the RU for transmitting the sensing signal; and the second sensing parameter determined by the DU can be a subset or a full set of the capability information of the RU for transmitting the echo signal.

[0108] To further improve the accuracy of the sensing parameter, in addition to determining the sensing parameter according to the first information, the DU can further determine the first sensing parameter and the second sensing parameter according to the first information, capability information of the DU, and / or sensing service requirement.

[0109] The sensing service requirement includes at least one of the following: accuracy of positioning, accuracy of velocity, sensing resolution, missed detection, false alarm, confidence level, max sensing service latency, and refreshing rate.

[0110] The accuracy of positioning, which can also be referred to as positioning / distance accuracy or positioning / distance accuracy, describes the closeness of the sensing measurement result (i.e., distance / position) of a target object to its true measurement value. It can be further divided into horizontal positioning / distance accuracy (referring to positioning / distance error in a two-dimensional reference or horizontal plane) and vertical positioning / distance accuracy (referring to positioning / distance error in a vertical axis or height).

[0111] The accuracy of velocity, which can also be referred to as velocity accuracy / precision, describes the closeness of the sensing measurement result (i.e., velocity) of a target object to its true velocity. It can be further divided into horizontal velocity accuracy (referring to velocity error in a two-dimensional reference or horizontal plane) and vertical velocity accuracy (referring to velocity error in a vertical axis or height).

[0112] The sensing resolution describes the minimum difference value (e.g., distance, velocity) required to detect different objects from a certain measurement dimension (e.g., distance, velocity).

[0113] The miss rate describes the conditional probability that the presence of the target object / environment is not detected when the target object / environment is present. This probability is represented by the ratio of the number of events that are falsely identified as negative to the total number of events that have a positive status (i.e. events that are falsely identified as negative and events that are correctly identified as positive).

[0114] The false alarm rate describes the conditional probability that the presence of the target object / environment is falsely detected when the target object / environment is not present. This probability is represented by the ratio of the number of events that are falsely identified as positive to the total number of events that have a negative status (i.e. events that are falsely identified as positive and events that are correctly identified as negative). It is only applicable to binary detection results.

[0115] The confidence level describes the percentage of correct results among all perception measurements at a certain perception accuracy.

[0116] The maximum perception service latency refers to the time elapsed between the occurrence of a real event and the availability of the perception result for the event at the perception system interface.

[0117] The refresh rate refers to the rate / frequency at which the perception system generates perception results. It is the inverse of the interval time between two consecutive detection results.

[0118] For example, in a low-altitude perception scenario and the perception capability reported by the RU meets the perception service requirement, the first perception parameter determined by the DU can be: the first symbol in the first and fifth time slots in every 10 ms, bandwidth, full channel, horizontal scanning A beams, vertical scanning B beams, and transmission power Pdbm.

[0119] For another example, in a channel perception scenario and the perception capability reported by the RU meets the perception service requirement, the first perception parameter determined by the DU can be: the first symbol in the fifth time slot in every 10 ms, frequency domain x~x+y Hz, first 1 / 4 channel, full channel, horizontal scanning 1 beam, vertical scanning 1 beam, and transmission power Qdbm.

[0120] S303. The DU sends second information to the RU.

[0121] Correspondingly, the RU receives the second information.

[0122] After the DU determines the first perception parameter and the second perception parameter, the DU can send second information to the RU. The second information indicates the first perception parameter and the second perception parameter.

[0123] Exemplarily, the first information indicates the capability information of the RU, and the second information indicates the first perception parameter and the second perception parameter, which can have the following two implementations:

[0124] In one implementation, the RU reports its capability information for a certain sensing service scenario, and the DU determines the first sensing parameter and the second sensing parameter according to the capability information of the RU, the capability information of the DU, and the current sensing service requirement, and indicates the first sensing parameter and the second sensing parameter for the sensing service scenario or corresponding to the current sensing service requirement through the second information.

[0125] In another implementation, the first information includes capability information of at least one capability level, and the capability information of at least one capability level is used to indicate the capability information corresponding to at least one sensing service requirement. The second information includes capability information of a first capability level, and the first capability level is one of the at least one capability level.

[0126] For example, the RU can define the sensing capabilities required in various sensing scenarios as different levels based on the integrated sensing service scenario, as shown in Table 1 below. The RU reports the capability information of the RU of at least one capability level to the DU. The DU can determine the capability information of the RU of the first capability level for the current sensing task according to the capability information of the RU of at least one capability level reported by the RU. Exemplarily, the DU sends the second information to the RU, which can be specific parameter information (i.e., the parameter corresponding to the first capability level) or an indication of the effective first capability level based on Table 1. For example, the RU reports the capability of supporting categories (Cat) 1-5, and the DU finally activates the capability of category 3. The capability level here is used to identify at least one of the following capability information of the RU: sensing capability, time domain information, bandwidth information, channel information, beam information, power information, format, scanning angle, horizontal distance, vertical distance, sensing speed resolution, angle resolution, time domain information, bandwidth information, channel information, beam information, power information corresponding to the echo signal.

[0127] Table 1

[0128] S304. The RU sends the sensing signal based on the first sensing parameter.

[0129] Correspondingly, the sensing target directly receives the sensing signal, or receives the sensing signal scattered, refracted, or reflected by the scatterer.

[0130] After receiving the second information, the RU can send the sensing signal based on the first sensing parameter.

[0131] The RU can directly generate the sensing signal according to the first sensing parameter and send it. For example, the RU directly generates the sensing signal, completes digital processing and analog processing, and finally sends it out at the specified time on the air interface.

[0132] The RU can also receive the digital signal sent by the DU, generate a sensing signal based on the digital signal, and send the sensing signal. For example, the DU prepares the corresponding digital signal in advance at each time point when the sensing signal needs to be sent, and sends the digital signal to the RU; the RU completes digital processing and analog processing, and finally sends the sensing signal at a specified time point in the air interface.

[0133] S305. The RU sends a backwave signal to the DU based on the second sensing parameter.

[0134] Correspondingly, the DU receives the backwave signal.

[0135] After the RU sends the sensing signal, the RU receives a backwave signal reflected / refracted by the sensing target, and sends the backwave signal to the DU based on the second sensing parameter. For example, the RU receives the backwave signal, processes the backwave signal, and finally reports a digital signal to the DU for further processing.

[0136] Exemplarily, the RU can send the backwave signal based on the second sensing parameter through the first interface.

[0137] In one example, the RU can multiplex an existing front-haul interface, and return the backwave signal and the communication uplink service signal to the DU, that is, the first interface is used not only to send the backwave signal, but also to transmit the communication signal.

[0138] In another example, the RU can establish a new front-haul interface for sensing only between the RU and the DU, and return the backwave signal to the DU. That is, the first interface is different from the interface used to transmit the communication signal. The front-haul interface for sensing here can use an independent physical line connection, such as an independent optical fiber; or can multiplex an existing communication physical connection, but a new independent logical interface is established.

[0139] According to the sensing method provided in the embodiment of the present application, the DU can configure the sensing parameters based on the capability information of the RU by receiving the capability information of the RU, so that the DU and the RU jointly complete the sensing task.

[0140] In addition to the above embodiment description that the DU can control how the RU sends the sensing signal and the backwave signal (configures the first sensing parameter and the second sensing parameter), the following embodiment will describe that the DU can also instruct the RU to start or stop the sensing task:

[0141] As shown in FIG. 4, it is a flow diagram of another sensing method provided in the embodiment of the present application. Exemplarily, the method can include the following steps:

[0142] S401. The RU sends first information to the DU.

[0143] Correspondingly, the DU receives the first information.

[0144] The first information indicates capability information of the RU. The capability information of the RU includes sensing capability.

[0145] Further, the capability information of the RU further includes at least one of: time domain information, bandwidth information, channel information, beam information, power information, format, scanning angle, horizontal distance, vertical distance, sensing speed resolution, angle resolution, of the sensing signal, and time domain information, bandwidth information, channel information, beam information, power information, of the echo signal.

[0146] The specific implementation of this step can refer to step S301 of the embodiment shown in FIG. 3, and will not be repeated here.

[0147] S402. The DU determines first sensing parameters and second sensing parameters according to the first information.

[0148] The first sensing parameters are used for configuring the sensing signal, and the second sensing parameters are used for configuring the echo signal.

[0149] The specific implementation of this step can refer to step S302 of the embodiment shown in FIG. 3, and will not be repeated here.

[0150] S403. The DU sends second information to the RU.

[0151] Correspondingly, the RU receives the second information.

[0152] The second information indicates the first sensing parameters and the second sensing parameters.

[0153] The specific implementation of this step can refer to step S303 of the embodiment shown in FIG. 3, and will not be repeated here.

[0154] S404. The DU sends third information to the RU.

[0155] Correspondingly, the RU receives the third information.

[0156] When the DU instructs the RU to perform the sensing service, the DU can send third information to the RU, where the third information indicates starting the sensing task.

[0157] Further, the RU can also send a first response to the DU, where the first response indicates receiving the third information. After the RU sends the first response, the RU starts to perform the sensing task.

[0158] S405. The DU sends a digital signal to the RU.

[0159] Correspondingly, the RU receives the digital signal.

[0160] The digital signal is used to generate the sensing signal.

[0161] The DU can prepare the corresponding digital signal in advance and send it to the RU at each time point when the sensing signal needs to be sent; the RU completes digital processing and analog processing, and finally sends it out at the specified time point in the air interface.

[0162] The RU does not need to generate the sensing signal by itself, reducing the demand for the computing capability of the RU.

[0163] S406. The RU sends the sensing signal based on the first sensing parameter.

[0164] Correspondingly, the sensing target directly receives the sensing signal, or receives the sensing signal after being refracted or reflected by the scatterer.

[0165] The specific implementation of this step can refer to step S304 of the embodiment shown in FIG. 3, and will not be described here again.

[0166] S407. The RU sends the echo signal to the DU based on the second sensing parameter.

[0167] Correspondingly, the DU receives the echo signal.

[0168] The specific implementation of this step can refer to step S305 of the embodiment shown in FIG. 3, and will not be described here again.

[0169] S408. The DU sends the fourth information to the RU.

[0170] Correspondingly, the RU receives the fourth information.

[0171] After the DU receives the echo signal, the DU can send the fourth information to the RU, where the fourth information indicates to stop the sensing task.

[0172] Further, the RU can also send a second response to the DU, where the second response indicates that the fourth information is received. After the RU sends the second response, the RU stops performing the sensing task.

[0173] According to the sensing method provided in the embodiments of the present application, the DU can configure the sensing parameter based on the capability information of the RU by receiving the capability information of the RU, so as to realize that the DU and the RU jointly complete the sensing task, and the DU can also instruct the RU to start or stop the sensing task.

[0176] Based on the same concept of the above-mentioned perception method, the present application also provides a perception apparatus as follows:
