It can fully share the spatial, temporal, and frequency resources of wireless communication and radar sensing, and realize the coexistence, mutual assistance, and mutual benefit of the two. Therefore, ISAC technology is widely used in different scenarios such as drone surveillance, maritime defense, and intelligent transportation.

However, as the integration of sensing and communication technologies becomes more commercialized, the complexity of test platforms also increases.

[0095] In the embodiments of this application, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0096] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0097] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0098] Currently, the integrated sensing and communication scenario utilizes traditional wireless communication equipment, upgrading its hardware and software to add sensing capabilities. This achieves a low-cost, continuous sensing network with minimal impact on existing communications, and can be widely applied in emerging scenarios such as drone surveillance, maritime defense, and intelligent transportation. Unlike traditional communication base station and terminal interaction, the sensing function primarily detects targets by receiving reflected echo signals, without requiring interaction with the target. Sensing encompasses various sensing modes, including base station A transmitting and receiving, base station A transmitting and receiving at B, base station transmitting and terminal receiving, terminal transmitting and base station receiving, terminal self-transmission and self-reception, and terminal mutual transmission.

[0099] In existing 5G NR systems, only communication functions are considered, and the test platform design is relatively simple, with only one communication test mode. With the imminent commercialization of the key technology of integrated sensing, the complexity of the test platform is also increasing. At the same time, the early verification cost of testing and verifying integrated sensing scenarios in real-world scenarios is too high. Expensive drone rental or boat rental fees, as well as the influence of weather factors, will increase the testing cost.

[0100] In view of this, this application proposes an automated testing method and a sensing integration testing system for key technologies of communication and sensing integration based on the main scenarios and application directions of sensing integration in the laboratory under the 5G-Advance system to simulate real-world scenarios.

[0101] The inductive integration testing method provided in this application embodiment can be applied to, for example... Figure 1 The integrated sensing and communication testing system shown is a beamforming subsystem, a sensing subsystem, a communication subsystem, an integrated sensing and communication testing subsystem, and control equipment. The beamforming subsystem consists of a signal generator and a spectrum analyzer; the sensing subsystem consists of a phase shifter and an echo simulator; the communication subsystem consists of a channel simulator and a phase shifter; and the integrated sensing and communication testing subsystem consists of a phase shifter, an echo simulator, and a channel simulator. The control equipment can be connected to the signal generator, spectrum analyzer, phase shifter, channel simulator, and echo simulator via a gateway switch. All components (signal generator, spectrum analyzer, phase shifter, channel simulator, and echo simulator) can be connected to the gateway switch via RJ-45 interfaces. The gateway switch connects to the control equipment, which can install I / O libraries software. The device software can communicate with other devices via a TCP / IP protocol interface. The control equipment also communicates with the base station side (…). Figure 1 (not shown in the image) and terminal side ( Figure 1(Not shown in the diagram) Connections. The signal generator, spectrum analyzer, phase shifter, echo meter, and channel simulator are connected via a synchronous connection link, enabling synchronous signal connection and communication. The beamforming test subsystem is used to perform gain testing on beamforming based on the beamforming weights of the communication transmission direction and the sensing transmission and reception direction. The sensing test subsystem is used to simulate sensing targets in different scenarios for related tests. The communication test subsystem is used to verify the uplink and downlink signal rates of users under the wireless channel. The integrated sensing and communication test subsystem is used to verify communication and sensing functions. Control devices can be, but are not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can be smart speakers, smart TVs, smart air conditioners, smart vehicle devices, projection devices, etc. Portable wearable devices can be smartwatches, smart bracelets, head-mounted devices, etc. Head-mounted devices can be virtual reality (VR) devices, augmented reality (AR) devices, smart glasses, etc. The control device can also be a server, which can be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The integrated sensor testing system can cover scenarios including low altitude, airways, sea areas, and ground-to-air environments to simulate real-world tests requiring drones, aerial photography, etc., in the laboratory.

[0102] In one exemplary embodiment, such as Figure 2 As shown, a test method for integrated sensing is provided, which is applied to... Figure 1 The following explanation uses the control equipment in the example:

[0103] S201, Determine the target test mode based on the access status of the user and sensing target of the integrated sensor test system.

[0104] The target test mode includes any one of the following: beam test mode, sensing test mode, communication test mode, and integrated sensing test mode.

[0105] Optionally, the beamforming test mode includes functions such as integrated sensing and communication testing, beamforming weights for the communication and sensing transmission / reception directions, and beamforming gain testing. The test principle of the beamforming test mode is as follows: the base station transmits downlink communication or sensing signals. Before each signal transmission, a preset beamforming angle is configured on the base station side. After the communication or sensing signal is loaded with phase files corresponding to the horizontal and vertical angles in the phase shifter, the corresponding time-domain power of the signal can be viewed on the spectrum analyzer. Therefore, the beamforming test mode can achieve beamforming testing by automatically configuring the phase shifter and automatically reading the average bandwidth power of the corresponding signal's time-frequency domain position from the spectrum analyzer, and comparing it with expectations.

[0106] Optionally, the perception test mode includes functions such as performing integrated sensing and simulating automatic detection of sensing targets. The testing principle of the perception test mode is to simulate perception test scenarios in the laboratory. Specifically, an echo simulator is used to add time delay and frequency offset to the sensing signal emitted by the base station, thereby simulating the drone or ship that generates the echo. A phase shifter is used to simulate the angular changes of the drone or ship in the air interface range in the real scene, thereby simulating the complex motion trajectory of the drone or ship.

[0107] Optionally, the communication test mode includes functions to verify user uplink and downlink rates under a wireless channel. The testing principle of the communication test mode is as follows: a channel simulator simulates changes in the wireless communication environment, and a phase shifter simulates changes in spatial angles, thereby testing wireless communication motion scenarios.

[0108] Optionally, the integrated sensing test mode includes laboratory simulation verification of communication and sensing functions under integrated sensing conditions. The testing principle of the integrated sensing test mode is as follows: it verifies the integrated communication and sensing performance under scenarios of superimposed air interface angle changes and beam coverage area changes in wireless communication environments using different instruments.

[0109] The method described in this application embodiment can be applied to a sensor-integrated testing system. This system can cover scenarios including low-altitude, airways, sea areas, and ground-to-air environments to simulate real-world testing scenarios requiring drones and ships in a laboratory. The system has two triggering modes: automated and manual. In automated triggering mode, the control device can detect the current user access status and the status of the sensing target, thereby determining the appropriate testing mode, such as beamforming, sensing, communication, or sensor-integrated testing. In manual triggering mode, the control device can switch between different testing modes in response to user triggering operations on the testing interface. For example, the testing interface includes test controls for beamforming, sensing, communication, and sensor-integrated testing modes. When a user triggers the corresponding test control on the testing interface, the control device responds to the triggering operation and directly performs the test in the corresponding test mode. For example, when the control terminal obtains information about the user and sensing target of the integrated sensing test system, it can display the user information of the currently connected user and the target information of the sensing target on the test interface for the user to view. Based on this information, the target test mode can be determined, and the corresponding test control operation can be triggered. The control device can then respond to the target test mode and perform the test in that mode.

[0110] It should be noted that the four test modes of the integrated sensing test system involved in this application differ from the individual tests of sensing and communication in the following ways: First, the communication beam coverage weights differ from those in the sensing mode. Specifically, the communication beam coverage weights cover the synchronization signal, while the sensing mode covers the sensing pulse wave or continuous wave signal. The combination of integrated sensing test simulations can verify the performance of sensing detection and wireless communication in the following scenarios: 1. UAVs or ships performing sensing detection and wireless communication under conditions where existing or changed communication beam coverage remains unchanged, corresponding to the aforementioned communication beam test mode; 2. UAVs or ships performing sensing detection and wireless communication performance under conditions where existing communication beam coverage remains unchanged, but changed sensing beam coverage, corresponding to the aforementioned sensing test mode; 3. UAVs or ships performing sensing detection and wireless communication performance under conditions where both communication beam coverage and sensing beam coverage change, corresponding to the integrated sensing test mode. The integrated sensing and communication testing mode can fully cover the performance scenarios of sensing and wireless communication under the combined testing and verification of communication beamforming weights and sensing beamforming weights. Secondly, the integrated sensing and communication testing mode achieves the superposition of the communication channel model and the sensing channel model. That is, if only the communication channel model is used, it can only simulate the non-line-of-sight (NLOS) or line-of-sight (LOS) channel scenarios of the testing and verification standards. However, the sensing channel is subject to environmental clutter interference such as clouds, rain, sea, ground, and foliage. Therefore, the integrated sensing and communication testing mode can simulate both the wireless communication channel and the sensing clutter channel to verify the system performance of communication and sensing.

[0111] S202, control the target test equipment corresponding to the target test mode to perform the test and obtain the test results.

[0112] The target test equipment may include at least two of the following from the integrated sensing and communication test system: a signal generator, a spectrum analyzer, a phase shifter, an echo meter, and a channel simulator. Different target test modes correspond to different target test equipment. For example, the target test equipment for the beam testing mode may include a phase shifter, a spectrum analyzer, and a signal generator; the target test equipment for the sensing test mode may include a phase shifter and an echo simulator; the target test equipment for the communication test mode may include a phase shifter and a channel simulator; and the target test equipment for the integrated sensing and communication test mode may include a phase shifter, a channel simulator, and an echo simulator.

[0113] In this embodiment of the application, when the control device determines the target test mode based on the aforementioned steps, it can further call the target test device corresponding to the target test mode to construct the corresponding test subsystem, and control the corresponding test subsystem to perform the test under the corresponding test mode. For example, see... Figure 1 The test system shown can be configured in several ways. If the target test mode is beamforming, a signal generator, spectrum analyzer, and phase shifter are used to construct a corresponding beamforming subsystem. The control equipment then controls the devices or instruments within this subsystem to perform beamforming gain testing on the beamforming weights for the communication transmission direction and the sensing transmission and reception direction in a sensory integration scenario. If the target test mode is sensing, an echo simulator and phase shifter are used to construct a corresponding sensing subsystem. The control equipment then controls the devices or instruments within this subsystem to simulate sensing targets in a sensory integration scenario. If the target test mode is communication, a channel simulator and phase shifter are used to construct a corresponding communication subsystem. The control equipment then controls the devices or instruments within this subsystem to verify the user uplink and downlink rates under the wireless channel. If the target test mode is sensory integration, a channel simulator, phase shifter, and echo simulator are used to construct a corresponding sensory integration test subsystem. The control equipment then controls the devices or instruments within this subsystem to perform laboratory simulation verification of the communication and sensing functions in a sensory integration scenario.

[0114] The sensing integration testing method described in the above embodiments is applied to a sensing integration testing system. This method determines the target testing mode based on the user and sensing target access conditions of the sensing integration testing system, and controls the target testing equipment corresponding to the target testing mode to perform testing and obtain test results. The target testing mode includes any one of beamforming testing mode, sensing testing mode, communication testing mode, and sensing integration testing mode. This method realizes an automated testing method for key technologies of communication and sensing integration in a laboratory simulating real-world scenarios. Moreover, by automatically switching between multiple different testing modes, it can achieve sensing integration testing covering different scenarios such as low-altitude, aviation, maritime, and ground-to-air environments. It eliminates the need for expensive physical equipment rental for testing, greatly reducing testing costs and improving testing efficiency.

[0115] In some exemplary embodiments, a method for controlling a target testing device to perform testing is provided, such as... Figure 3 As shown, this method includes:

[0116] S301, Determine the target test mode. If the target test mode is the integrated sensor test mode, proceed to step S302; if the target test mode is the perception test mode, proceed to step S303; if the target test mode is the beam test mode, proceed to step S304.

[0117] S302, the phase shifter, echo simulator, and channel simulator corresponding to the integrated sensing test mode in the integrated sensing test system are tested to obtain the test results.

[0118] S303, the phase shifter and echo simulator corresponding to the sensing test mode in the integrated control and sensing test system are tested to obtain the test results.

[0119] S304, the signal generator, phase shifter and spectrum analyzer corresponding to the beam test mode in the integrated control and sensing test system are tested to obtain the test results.

[0120] In this application embodiment, different target test modes correspond to different target test devices, and different target test devices construct different test subsystems. For example, a phase shifter, an echo simulator, and a channel simulator form an integrated sensing test subsystem; a phase shifter and an echo simulator form a sensing test subsystem; a signal generator, a phase shifter, and a spectrum analyzer form a beam test subsystem; and a channel simulator and a phase shifter form a communication test subsystem. See [link to relevant documentation]. Figure 1 As shown. When the control device determines the target test mode of the current integrated sensing test system based on the aforementioned steps, if the target test mode is determined to be an integrated sensing test mode, it can further call the phase shifter, echo simulator, and channel simulator corresponding to the target integrated sensing test mode to construct an integrated sensing test subsystem, and control the phase shifter, echo simulator, and channel simulator to work together to realize integrated sensing test and obtain the test results in the integrated sensing test mode. If the target test mode is determined to be a sensing test mode, it can further call the phase shifter and echo simulator corresponding to the target sensing test mode to construct a sensing test subsystem, and control the phase shifter and echo simulator to work together to realize the sensing test subsystem and obtain the test results in the sensing test mode; if the target test mode is determined to be a beam test mode, it can further call the signal generator, phase shifter, and spectrum analyzer corresponding to the beam test mode to construct a sensing test subsystem, and control the signal generator, phase shifter, and spectrum analyzer to work together to realize the beam test subsystem and obtain the test results in the beam test mode.

[0121] The sensory integration testing method described in the above embodiments can flexibly construct different testing subsystems for testing according to different testing modes, which can improve the applicability and flexibility of the entire sensory integration testing system.

[0122] In some exemplary embodiments, a method for synesthetic integration testing is provided where the target test mode is a synesthetic integration test mode, such as... Figure 4 As shown, the method includes:

[0123] S401, load the first scene angle file on the phase shifter, load the first scene simulation file on the echo simulator, and load the second scene simulation file on the channel simulator.

[0124] The main function of the phase shifter in this embodiment is to simulate the angle changes of drones, ships or other moving targets in the air interface range in real-world scenarios. The corresponding first scene angle file includes sampling point information of angle modulation for different angle changes. Correspondingly, the phase shifter in this embodiment also has another function: to simulate downlink signals entering different channel environments. Therefore, the corresponding first scene angle file includes sampling point information of different angle changes and rate changes.

[0125] The main function of the echo simulator in this embodiment is to add time delay and frequency offset to the test signal sent from the base station, thereby simulating the echo generated by a drone, ship, or other moving target. The corresponding first scenario simulation file includes sampling point information with different time delays and frequency offsets. The main function of the channel simulator is to simulate changes in the wireless communication environment and verify the user's uplink and downlink rates under the wireless channel. The corresponding second scenario simulation file includes sampling point information of downlink signals with different angles and rates.

[0126] This embodiment involves a method for configuring a phase shifter, namely, preloading a first scene angle file onto the phase shifter so that the phase shifter can simulate the angle changes of drones, ships or other moving targets in real-world scenarios within the air interface range, as well as simulate downlink signals with different angles and rates, facilitating subsequent measurements on different channels.

[0127] This embodiment also involves a configuration method for the echo simulator and the channel simulator, namely, loading a first scenario simulation file in advance on the echo simulator, so that the echo simulator adds time delay and frequency offset to the test signal sent down from the base station, thereby simulating the drone, ship or other moving target that generates the echo; loading a second scenario simulation file in advance on the channel simulator, thereby simulating downlink signals with different angles and rates, which is convenient for subsequent measurement of different channels.

[0128] Optionally, after loading the first scene angle file on the phase shifter, the first scene simulation file on the echo simulator, and the second scene simulation file on the channel simulator, the base station can also enable the log recording function on the base station side, so that the base station can record the process data or test data of the entire subsequent test process.

[0129] S402, send the first control signaling to the base station side.

[0130] The first control signaling is used to instruct the phase shifter and echo simulator, after lateral loading at the base station, to send a first trigger synchronization signal and a first test signal. The first trigger synchronization signal is used to trigger the phase shifter and echo simulator in the integrated inductive testing subsystem to synchronize signals. Optionally, the first trigger synchronization signal can be a periodic pulse synchronization signal.

[0131] S403, based on the first trigger synchronization signal and the first test signal, controls the loaded phase shifter, the loaded echo simulator and the channel simulator to perform tests and obtain test results.

[0132] In this embodiment of the application, when the base station generates a first trigger synchronization signal and a first test signal based on the aforementioned steps and the first control signaling, on the one hand, the first trigger synchronization signal can be sent to the phase shifter and the echo simulator, so that the phase shifter and the echo simulator can maintain time synchronization, thereby ensuring the accuracy of the perceived target trajectory; on the other hand, the first test signal can be sent to the phase shifter, so that the phase shifter can modulate the first test signal based on the first scene angle file, and send the first test signal to the echo simulator, so that the echo simulator can process the first test signal based on the first scene simulation file, and control the channel simulator to perform channel environment simulation test, and finally obtain the test result.

[0133] Optionally, before the control device actually enters the integrated sensing test mode, the control device also needs to determine whether the current test mode has been switched to the integrated sensing test mode. The determination method includes: receiving a first detection signal sent by the base station; if the signal at a specific time slot position in the first detection signal meets the first preset signal condition, then the current test mode is determined to be switched to the integrated sensing test mode.

[0134] The first preset signal condition includes that the signal transmitted at the first time slot position in the first detection signal is a pulse wave signal, and a PUSCH signal exists at the second time slot position or a PDSCH signal exists at the third time slot position; or, the first preset signal condition includes that the signal transmitted at the first time slot position in the first detection signal is a pulse wave signal, and a PUSCH signal exists at the second time slot position and a PDSCH signal exists at the third time slot position. The first time slot position is slot0, slot5, slot10, or slot15 in the downlink frame structure at the location of the SSB center frequency point in the first detection signal; the second time slot position is slot18; and the third time slot position is slot16. When the control device detects that the signal transmitted at slot 0 / slot 5 / slot 10 / slot 15 in the downlink frame structure at the location of the SSB center frequency point is a pulse wave signal and there is a PUSCH signal at slot 18 or a PDSCH signal at slot 16; or, when the control device detects that the signal transmitted at slot 0 / slot 5 / slot 10 / slot 15 in the downlink frame structure at the location of the SSB center frequency point is a pulse wave signal and there is a PUSCH signal at slot 18 and a PDSCH signal at slot 16, it determines that the current test mode is switched to the integrated sensing test mode.

[0135] The method described in the above embodiments, by constructing an integrated sensing and communication testing subsystem using phase shifters, echo simulators, and channel simulators, achieves integrated sensing and communication testing. It adds different scenarios for communication and sensing testing to existing testing scenarios, meeting the needs of multi-scenario testing and significantly improving testing efficiency. Furthermore, in the integrated sensing and communication testing mode, corresponding to the complex environment of the integrated sensing and communication scenario, when simulating the movement of targets such as drones and ships in the laboratory, precise time synchronization of various instruments is required to ensure the testing performance of the entire system. Therefore, a base station-side output trigger synchronization signal is introduced, using a synchronization trigger model to move in millisecond-level time steps to ensure accurate perception of the target trajectory.

[0136] In some exemplary embodiments, an implementation method is provided for testing the loaded phase shifter, the loaded echo simulator, and the channel simulator, such as... Figure 5 As shown, the method includes:

[0137] S501 sends the first control command to the loaded phase shifter.

[0138] The first control command is used to instruct the phase shifter to modulate the first test signal according to the first scene angle file when it receives the first trigger synchronization signal, so as to obtain the first modulated signal.

[0139] S502 sends a second control command to the loaded echo simulator.

[0140] The second control command is used to instruct the echo simulator to process the first test signal according to the first scene simulation file when it receives the first trigger synchronization signal, so as to obtain the first processed signal.

[0141] S503 sends a third control command to the loaded channel simulator.

[0142] The third control instruction is used to instruct the channel simulator to process the first modulation signal according to the second scenario simulation file when it receives the first modulation signal, so as to obtain the second processed signal.

[0143] Optionally, after the phase shifter modulates the first test signal, the echo simulator processes the first test signal, and the channel simulator processes the first modulated signal, the log recording function on the base station side has recorded the test data and process data of the entire test process. Therefore, at this time, the control device can turn off the log recording function on the base station side.

[0144] S504, determine the test result based on the first modulation signal, the first processing signal, and the second processing signal.

[0145] This application embodiment relates to a test method in a sensor-integrated test mode. Specifically, when the control device determines the current test mode to be sensor-integrated based on the aforementioned steps, the control device sends a first control signaling command to the base station to trigger the issuance of a first trigger synchronization signal and also to trigger the issuance of a first test signal to the phase shifter and echo simulator. Afterward, the control device sends a first control command to the phase shifter, enabling it to synchronize time according to the first trigger synchronization signal and modulate the phase of the first test signal according to a pre-loaded first scene angle file, generating a modulated fourth modulation signal to simulate the angle changes of a drone, ship, or other moving target within the air interface range in a real-world scenario. Simultaneously, the control device also controls the phase shifter to output the first modulation signal to the channel simulator. Then, the control device sends a second control command to the echo simulator, enabling it to synchronize time according to the first trigger synchronization signal and process the first test signal for time delay and frequency offset according to a pre-loaded first scene simulation file, obtaining a first processed signal to simulate a drone, ship, or other moving target generating an echo. The control device sends a third control command to the channel simulator, enabling the simulator to process a portion of the first modulation signal output from the phase shifter communication channel to obtain a second processed signal, thus simulating signals under different channel environments. Finally, the control device can determine the air interface range angle changes, movement distance and trajectory of the UAV, ship, or other moving target, as well as the changes in the user's downlink signal, based on the first modulation signal, the first processed signal, and the second processed signal. This data is then compared and analyzed to obtain the test results. Optionally, if the base station's log recording function is activated during the above test process, the control device can obtain the first modulation signal, the first processed signal, and the second processed signal by reading the base station's log records. Based on these signals, the control device can determine the air interface range angle changes, movement distance and trajectory of the UAV, ship, or other moving target, as well as the changes in the user's downlink signal, and then compare and analyze this data to obtain the test results.

[0146] Optionally, before the control device actually enters the perception test mode, the control device also needs to determine whether the current test mode has been switched to the perception test mode. The determination method includes: receiving a first detection signal sent by the base station; if the signal at a specific time slot position in the first detection signal meets the second preset signal condition, then the current test mode is determined to be switched to the perception test mode.

[0147] The second preset signal condition includes that the signal transmitted at the first time slot position in the first detection signal is a pulse wave signal, and there is no Physical Uplink Shared Channel (PUSCH) signal at the second time slot position, and no Physical Downlink Shared Channel (PDSCH) signal at the third time slot position. The first time slot position is slot 0, slot 5, slot 10, or slot 15 in the downlink frame structure at the location of the SSB center frequency point in the first detection signal; the second time slot position is slot 18; and the third time slot position is slot 16. Specifically, when the control device detects that the signal transmitted at slot 0 / slot 5 / slot 10 / slot 15 in the downlink frame structure at the location of the SSB center frequency point is a pulse wave signal, and there is no PUSCH signal at slot 18 and no PDSCH signal at slot 16, it determines that the current test mode is switched to the sensing test mode.

[0148] In some exemplary embodiments, a method for perception testing with the target testing mode being a perception testing mode is provided, such as... Figure 6 As shown, the method includes:

[0149] S601 loads the second scene angle file on the phase shifter and the third scene simulation file on the echo simulator.

[0150] The main function of the phase shifter in this embodiment is to simulate the angle changes of drones, ships, or other moving targets within the air interface range in real-world scenarios. The corresponding third-scenario angle file includes sampling point information for angle modulation of different angle changes. The main function of the echo simulator in this embodiment is to add time delay and frequency offset to the test signal sent from the base station side, thereby simulating the drones, ships, or other moving targets that generate echoes. The corresponding third-scenario simulation file includes sampling point information for different time delays and frequency offsets. The third-scenario angle file can be determined in advance based on the expected air interface range angle change test requirements; the third-scenario simulation file can be determined in advance based on the expected behavior distance and trajectory test requirements of drones, ships, or other moving targets.

[0151] This embodiment involves a configuration method for a phase shifter and an echo simulator. Specifically, a second scene angle file is preloaded onto the phase shifter, enabling the phase shifter to simulate the angle changes of drones, ships, or other moving targets within the air interface range in real-world scenarios. A third scene simulation file is preloaded onto the echo simulator, allowing the echo simulator to add time delay and frequency offset to the test signal sent from the base station, thereby simulating the drones, ships, or other moving targets that generate echoes.

[0152] Optionally, after loading the second scene angle file on the phase shifter and the third scene simulation file on the echo simulator, the base station side can also be logged, so that the base station can record process data or test data of the entire subsequent test process.

[0153] S602, sends a second control signaling to the base station side.

[0154] The second control signaling is used to instruct the phase shifter and echo simulator after lateral loading at the base station to send a second trigger synchronization signal and a second test signal. The second trigger synchronization signal is used to trigger the phase shifter and echo simulator in the sensing test subsystem to synchronize signals. Optionally, the second trigger synchronization signal can be a periodic pulse synchronization signal.

[0155] S603 controls the loaded phase shifter and the loaded echo simulator to perform tests based on the second trigger synchronization signal and the second test signal, and obtains the test results.

[0156] In this embodiment, when the base station generates a second trigger synchronization signal and a second test signal based on the aforementioned steps and the second control signaling, it can send the second trigger synchronization signal to the phase shifter and the echo simulator, so that the phase shifter and the echo simulator can maintain time synchronization and ensure the accuracy of the perceived target trajectory. On the other hand, it can send the second test signal to the phase shifter, so that the phase shifter can modulate the second test signal based on the second scene angle file, and send the second test signal to the echo simulator, so that the echo simulator can process the second test signal based on the third scene simulation file, and finally obtain the test result.

[0157] The method described in the above embodiments, by constructing a perception test subsystem using a phase shifter and an echo simulator, realizes integrated perception testing, adds perception testing to existing test scenarios, and can greatly improve test efficiency.

[0158] In some exemplary embodiments, an implementation method is provided for controlling the loaded phase shifter and the loaded echo simulator for testing, such as... Figure 7 As shown, the method includes:

[0159] S701 sends the fourth control command to the loaded phase shifter.

[0160] The fourth control command is used to instruct the phase shifter to modulate the second test signal according to the second scene angle file when it receives the second trigger synchronization signal, so as to obtain the second modulated signal.

[0161] S702 sends the fifth control command to the loaded echo simulator.

[0162] The fifth control instruction is used to instruct the echo simulator to process the second test signal according to the third scenario simulation file when it receives the second trigger synchronization signal, so as to obtain the third processed signal.

[0163] Optionally, after the phase shifter modulates the second test signal and the echo simulator processes the second test signal, the log recording function on the base station side has recorded the test data and process data of the entire test process. Therefore, at this time, the control device can turn off the log recording function on the base station side.

[0164] S703 determines the test result based on the second modulation signal and the third processing signal.

[0165] This application embodiment relates to a perception testing method in a perception testing mode. Specifically, when the control device determines the current testing mode as perception testing mode based on the aforementioned steps, the control device sends a second control signaling to the base station to trigger the issuance of a second trigger synchronization signal and also triggers the issuance of a second test signal to the phase shifter and echo simulator. Afterward, the control device sends a fourth control command to the phase shifter, enabling it to synchronize time according to the second trigger synchronization signal and modulate the phase of the second test signal according to a pre-loaded second scene angle file, generating a modulated second signal to simulate the angle changes of a drone, ship, or other moving target within the air interface range in a real-world scenario. Correspondingly, the control device sends a fifth control command to the echo simulator, enabling it to synchronize time according to the second trigger synchronization signal and process the second test signal for time delay and frequency offset according to a pre-loaded third scene simulation file, obtaining a third processed signal to simulate the drone, ship, or other moving target generating the echo. Finally, the control device can determine the air interface range angle change, movement distance, and trajectory of the UAV, ship, or other moving target based on the second modulation signal and the third processing signal. This data is then compared and analyzed to obtain the test results. Optionally, if the base station's log recording function is activated during the above test, the control device can obtain the second modulation signal and the third processing signal by reading the base station's log records. Based on these signals, it can determine the air interface range angle change, movement distance, and trajectory of the UAV, ship, or other moving target, and then compare and analyze this data to obtain the test results.

[0166] In some exemplary embodiments, a method is provided where the target test mode is a sensing test mode or a synesthetic integrated test mode, i.e., a synesthetic integrated test system is used to perform sensing tests or synesthetic tests, such as... Figure 8 As shown, the method includes:

[0167] S801, determine whether the trigger synchronization signal function on the base station side is started. If it is determined that the trigger synchronization signal function is not started, proceed to step S802. If it is determined that the trigger synchronization signal function is started, proceed to step S803.

[0168] S802 controls the target test device corresponding to the target test mode to perform the test and obtain the test results.

[0169] S803 controls the base station to stop triggering the synchronization signal function, and then controls the target test equipment corresponding to the target test mode to perform the test and obtain the test results.

[0170] In this embodiment, under the original beam testing or communication testing modes, each instrument and device involved in the system operation works independently. Each instrument and device uses its own generated independent timestamp, and time synchronization between instruments and devices does not need to be accurate to the millisecond level to ensure the testing content can proceed. However, under the current sensing testing mode, when simulating drones and ship navigation in the laboratory, precise time synchronization of each instrument and device is required to ensure the testing performance of the entire system. Therefore, a base station TR trigger output synchronization signal method is introduced, i.e., the base station's trigger synchronization signal function. Specifically, when the base station outputs the trigger synchronization signal to each instrument and device, it can output a periodic pulse synchronization signal. After receiving the synchronization signal, the phase shifter, echo simulator, and channel simulator in the sensing testing subsystem or the integrated sensing subsystem synchronously trigger movement in millisecond-level time steps to ensure accurate target trajectory sensing. Based on the above explanation, when the control device determines that the target test mode is either the sensing test mode or the integrated sensing test mode based on the aforementioned steps, it can first determine whether the trigger synchronization signal function on the base station side is activated. If it is determined that the trigger synchronization signal function is not activated, the TRIGER synchronization signal can be configured and triggered based on the configured synchronization signal. Then, the target test device corresponding to the target test mode is controlled to perform the test according to the configured synchronization signal to obtain the test result. If it is determined that the trigger synchronization signal function is activated, the base station side is controlled to stop the trigger synchronization signal function. Then, the TRIGER synchronization signal is configured and triggered based on the configured synchronization signal, and the target test device corresponding to the target test mode is controlled to perform the test according to the configured synchronization signal to obtain the test result. It should be noted that when the target test mode is the sensing test mode, the corresponding target test device includes a phase shifter and an echo simulator, and also corresponds to a sensing test subsystem constructed from the phase shifter and the echo simulator; when the target test mode is the integrated sensing test mode, the corresponding target test device includes a phase shifter, an echo simulator, and a channel simulator, and also corresponds to an integrated sensing test subsystem constructed from the phase shifter, the echo simulator, and the channel simulator.

[0171] In some exemplary embodiments, before the control device determines whether the trigger synchronization signal function on the base station side is activated, it may also perform the following steps: select the current test scenario, and determine the transmission period of the trigger synchronization signal sent by the base station side based on the scenario angle file and scenario simulation file corresponding to the test scenario.

[0172] The test scenarios can include different scenarios such as low-altitude, airways, sea areas, and ground-to-air, each corresponding to different scenario angle files and scenario simulation files. Therefore, before actually entering the sensing test mode or the integrated sensing test mode, the control device needs to select the current test scenario and then obtain the corresponding scenario angle file and scenario simulation file. For example, if the current test mode is the integrated sensing test mode and the test scenario is a low-altitude test scenario, then the first scenario angle file, the first scenario simulation file, and the second scenario simulation file corresponding to that low-altitude test scenario are selected; if the current test mode is the sensing test mode and the test scenario is a low-altitude test scenario, then the second scenario angle file and the third scenario simulation file corresponding to that low-altitude test scenario are selected.

[0173] Optionally, after the control device selects the corresponding test scenario, since different test scenarios match different trigger synchronization signal transmission cycles, the control device also needs to configure the signal synchronization transmission cycle after selecting the test scenario and before actually entering the perception test. Based on this, after selecting the current test scenario, the control device also performs the following steps: determining the transmission cycle of the trigger synchronization signal sent by the base station side according to the scene angle file and scene simulation file corresponding to the test scenario. For example, when the target test mode is the perception test mode, the control device can also determine the transmission cycle of the trigger synchronization signal sent by the base station side according to the second scene angle file and third scene simulation file corresponding to the test scenario after selecting the current test scenario; when the target test mode is the integrated sensing test mode, the control device can also determine the transmission cycle of the trigger synchronization signal sent by the base station side according to the first scene angle file and first scene simulation file corresponding to the test scenario after selecting the current test scenario.

[0174] In this embodiment, since the trajectory in a real-world scenario is continuously changing, the distance and angle change trajectories in the laboratory simulation echo simulator are discrete sampling points. Naturally, a higher sampling rate results in more accurate trajectory simulation, but also increases the load on the echo simulator. Therefore, the period of the trigger synchronization signal sent by the base station (e.g., the first trigger synchronization signal or the second trigger synchronization signal) is further refined into five time periods, such as 5ms, 80ms, 100ms, 200ms, and 1000ms. Based on this, the control device can configure the transmission period of the base station synchronization signal according to the sampling interval or sampling frequency of the sampling points recorded in the scene angle file corresponding to the phase shifter and the scene simulation file corresponding to the echo simulator (e.g., the first scene simulation file or the second scene simulation file), so as to coordinate the signal synchronization of the echo simulator and the phase shifter. Specifically, the sampling interval is proportional to the time period. A matching time period can be selected from the above five time periods as the transmission period of the base station trigger synchronization signal. For example, if the sampling interval of the sampling points in the scene angle file is relatively short, the corresponding time period can be configured to be shorter, such as 5ms.

[0175] In some exemplary embodiments, a method for beam testing using a sensor-integrated testing system is provided, where the target test mode is a beam test mode. Figure 9 As shown, the method includes:

[0176] S901, load the third scene angle file on the phase shifter.

[0177] Specifically, the third scene angle file includes modulation information with a fixed horizontal angle and traversing the vertical angle, as well as modulation information with a fixed vertical angle and traversing the horizontal angle. The third scene angle file can be determined in advance according to the expected beam angle change test requirements.

[0178] S902 sends a third control signaling to the base station.

[0179] The third control signaling is used to instruct the phase shifter after the base station is laterally loaded to send a third test signal.

[0180] S903, based on the third test signal, controls the signal generator, the loaded phase shifter, and the spectrum analyzer corresponding to the beam test mode to perform tests and obtain test results.

[0181] In this embodiment of the application, when the base station generates a third test signal based on the aforementioned steps and the third control signaling, the third test signal can be sent to the phase shifter, so that the phase shifter can modulate the third test signal based on the third scene angle file, and the power value of the modulated signal can be read by the spectrum analyzer to realize beam testing.

[0182] In some exemplary embodiments, the beam test mode can be divided into communication beam test mode and sensing beam test mode. The sensing beam test mode can be further divided into sensing transmission test mode and sensing reception test mode. Based on these mode types, a test method under the beam test mode is also provided, such as... Figure 10 As shown, the method includes:

[0183] S1001, determine the mode type of the beam test mode; if the mode type is determined to be communication beam test mode or sensing transmission test mode, then execute step S1002; if the mode type is determined to be sensing reception test mode, then execute step S1003.

[0184] S1002, based on the third test signal, control and sense the phase shifter and spectrum analyzer corresponding to the test mode to perform the test and obtain the test results.

[0185] S1003, based on the third test signal, controls the signal generator, phase shifter and spectrum analyzer corresponding to the sensing and receiving test mode to perform tests and obtain test results.

[0186] Different test modes correspond to different target test equipment. For example, the target test equipment for the communication beam test mode includes a phase shifter and a spectrum analyzer; the target test equipment for the sensing beam test mode includes a phase shifter, a spectrum analyzer, and a signal generator.

[0187] In this embodiment, when the control device determines the target test mode as a beam test mode based on the aforementioned steps, since the beam test mode can be further subdivided into communication beam test mode and sensing beam test mode, and the sensing beam test mode is further divided into sensing transmission test mode and sensing reception test mode, it can be further determined which of the three beam test modes—communication beam test mode, sensing transmission test mode, and sensing reception test mode—or none of them. If the beam test mode is determined to be either a communication beam test mode or a sensing transmission test mode, it means that a trigger signal can be emitted from the base station side to conduct the test. Therefore, the phase shifter and spectrum analysis can be directly invoked at this time. The system comprises a beamforming subsystem, and the control equipment controls each device or instrument within it to perform beamforming gain testing on the beamforming weights of the communication transmission direction and the sensing transmission and reception direction in a sensing-integrated scenario. If the beamforming test mode is determined to be a sensing-reception test mode, it means that the signal generator can trigger the signal to emit a signal for testing. Therefore, the phase shifter, spectrum analyzer, and signal generator can be directly used to form the beamforming subsystem, and the control equipment controls each device or instrument within it to perform beamforming gain testing on the beamforming weights of the communication transmission direction and the sensing transmission and reception direction in a sensing-integrated scenario. If neither of these modes is determined, the testing process is terminated.

[0188] The method described in the above embodiments realizes integrated sensing and communication beam testing. Compared with the traditional single communication platform testing method, this method can perform not only single communication beam testing but also single sensing beam testing. Furthermore, by combining and switching between the two mode types, it achieves fully automatic integrated sensing and communication testing, which can greatly improve testing efficiency.

[0189] In some exemplary embodiments, a test method is provided in a communication beam test mode or a sensing transmission test mode, such as... Figure 11 As shown, the test method includes:

[0190] S1101, send the sixth control command to the phase shifter.

[0191] The sixth control instruction is used to instruct the phase shifter to modulate the third test signal according to the pre-loaded third scene angle file when it receives the third test signal, so as to obtain the third modulated signal.

[0192] S1102, send the seventh control command to the spectrum analyzer.

[0193] The seventh control command is used to instruct the spectrum analyzer to read the first power value of the third modulation signal.

[0194] S1103, determine the test result based on the third modulation signal and the first power value.

[0195] Among them, the third scene angle file can be determined in advance according to the expected beam angle change test requirements.

[0196] This application embodiment relates to a beam testing method in either a communication beam test mode or a sensing transmission test mode. Specifically, when the control device determines the current test mode to be either a communication beam test mode or a sensing transmission test mode based on the aforementioned steps, the control device sends a third control signal to the base station to trigger a third test signal to be sent to the phase shifter and spectrum analyzer. Afterward, the control device sends a sixth control command to the phase shifter and a seventh control command to the spectrum analyzer, enabling the phase shifter to modulate the phase of the third test signal according to a pre-recorded third scene angle file, generating a modulated third modulated signal. Specifically, the third scene angle file includes modulation information with a fixed horizontal angle and traversing vertical angles, as well as modulation information with a fixed vertical angle and traversing horizontal angles. Therefore, the phase shifter can cyclically modulate the phase of the third modulated signal according to different modulation information to obtain modulated signals at different frequency points. During the cyclic modulation of the signal by the phase shifter, the control device sends a seventh control command to the spectrum analyzer, enabling the spectrum analyzer to read the first power value of the signal at the corresponding frequency point position configured by the phase shifter. Finally, the control device can compare and analyze the third modulation signal, the first power value, and the expected data to obtain the test results.

[0197] The method described in the above embodiments, by using a phase shifter, a spectrum analyzer, and a signal generator to construct a beam testing subsystem, realizes integrated beam testing of inductive and transductive components, enables multi-scenario testing, and can greatly improve testing efficiency.

[0198] In some exemplary embodiments, a testing method is provided in a sensing reception test mode, such as... Figure 12 As shown, the test method includes:

[0199] S1201, send the eighth control command to the signal generator.

[0200] The eighth control command is used to instruct the signal generator to generate and send the fourth test signal to the phase shifter.

[0201] S1202, send the ninth control command to the phase shifter.

[0202] The ninth control instruction is used to instruct the phase shifter to modulate the fourth test signal according to the pre-loaded third scene angle file when it receives the fourth test signal, so as to obtain the fourth modulated signal.

[0203] S1203 sends the tenth control command to the spectrum analyzer.

[0204] The tenth control command is used to instruct the spectrum analyzer to read the second power value of the fourth modulation signal.

[0205] S1204, determine the test result based on the fourth modulation signal and the second power value.

[0206] This application embodiment relates to a beamforming test method in a sensing and receiving test mode. Specifically, when the control device determines the current test mode to be the sensing and receiving test mode based on the aforementioned steps, the control device sends an eighth control command to the signal generator, causing the signal generator to trigger a fourth test signal to be emitted to the phase shifter and spectrum analyzer. Afterward, the control device sends a ninth control command to the phase shifter and a tenth control command to the spectrum analyzer, enabling the phase shifter to modulate the fourth test signal according to a pre-loaded third scene angle file, generating a modulated fourth modulation signal. Specifically, the third scene angle file includes modulation information with a fixed horizontal angle and traversing vertical angles, as well as modulation information with a fixed vertical angle and traversing horizontal angles. Therefore, the phase shifter can cyclically modulate the fourth modulation signal according to different modulation information to obtain modulated signals at different frequency points. During the cyclic modulation of the signal by the phase shifter, the control device sends a tenth control command to the spectrum analyzer, enabling the spectrum analyzer to read the second power value of the signal at the corresponding frequency point position configured by the phase shifter. Finally, the control device can compare and analyze the fourth modulation signal, the second power value, and the expected data to obtain the test results.

[0207] The method described in the above embodiments, by constructing a beam testing subsystem using a phase shifter, a spectrum analyzer, and a signal generator, realizes beam testing of the sensing and receiving modes in the integration of sensing and communication, and realizes a method for testing multiple modes in beam testing, which enriches the testing requirements and can greatly improve the testing efficiency.

[0208] In some exemplary embodiments, one implementation for determining the mode type of a beam test mode is provided, such as... Figure 13 As shown, the method includes:

[0209] S1301, detect the second detection signal sent by the base station and the current sensing status of the integrated sensing test system; if the second detection signal and the sensing status meet the first preset detection condition, then execute step S1302; if the second detection signal and the sensing status meet the second preset detection condition, then execute step S1303; if the second detection signal and the sensing status meet the third preset detection condition, then execute step S1304.

[0210] The first preset detection condition includes the number of Synchronization Signal Blocks (SSBs) in the second detection signal reaching a preset threshold. The second preset detection condition includes the number of SSBs in the second detection signal not reaching the preset threshold, and the perception state indicating the presence of a sensing target in the integrated sensing and communication test system. The third preset detection condition includes the number of SSBs in the second detection signal not reaching the preset threshold, and the perception state indicating the absence of a sensing target in the integrated sensing and communication test system. Synchronization Signal Blocks (SSBs) are important pilot channels in 5G networks used for cell search and synchronization. They are involved not only in cell search and synchronization but also in beam measurement, selection, and recovery. The preset threshold can be determined according to actual test requirements; for example, the preset threshold could be seven. The perception state indicates the presence of a sensing target in the integrated sensing and communication test system.

[0211] S1302, Determine the mode type of the beam test mode as communication beam test mode.

[0212] S1303, the mode type of the beam test mode is determined to be the sensing transmission test mode.

[0213] S1304, The mode type of the beam test mode is determined to be the sensing and receiving test mode.

[0214] In this embodiment, the control device can receive a second detection signal sent by the base station and control the spectrum analyzer to read the number of SSB signal blocks in the second detection signal. When the number reaches a preset threshold, the mode type of the beam test mode is determined to be a communication beam test mode; when the number does not reach the preset threshold, the mode type of the beam test mode is determined to be a sensing beam test mode. For example, the control device can detect that there are 7 SSB blocks in the first two subframes of the downlink frame structure at the location of the SSB center frequency point in the second detection signal, and then determine that the current beam test mode is a communication beam test mode; otherwise, it is a sensing beam test mode. Once the control device determines the current beam test mode as the sensing beam test mode based on the aforementioned steps, since the sensing beam test mode can be further subdivided into sensing transmit test mode and sensing receive test mode, it can be further determined whether the sensing beam test mode belongs to the sensing transmit test mode, the sensing receive test mode, or neither. The control device can detect the sensing status of the current integrated sensing test system. If the detected sensing status indicates that there is a sensing target in the current integrated sensing test system, then the sensing beam test mode is determined to be the sensing transmit test mode. This means that at this time, a trigger signal can be emitted from the base station side for testing. Therefore, at this time, the phase shifter and spectrum analyzer corresponding to the sensing transmit test mode can be directly called to form a beam test subsystem, and then... The control equipment controls each device or instrument in the beamforming test subsystem to perform beamforming gain testing on the beamforming weights of the communication transmission direction and the sensing transmission and reception direction in a sensing-integrated scenario. If the detected sensing state indicates that there is no sensing target in the current sensing-integrated test system, the sensing beamforming test mode is determined to be the sensing reception test mode. This means that the signal generator can trigger the signal to be emitted for testing. Therefore, the phase shifter, spectrum analyzer, and signal generator corresponding to the sensing reception test mode can be directly called to form the beamforming test subsystem. The control equipment then controls each device or instrument in the beamforming test subsystem to perform beamforming gain testing on the beamforming weights of the communication transmission direction and the sensing transmission and reception direction in a sensing-integrated scenario.

[0215] The method described in the above embodiments divides the beam test mode into communication beam test mode, sensing transmission test mode, and sensing reception test mode, realizing testing for different sensing scenarios and providing richer multi-scenario testing methods, which can improve the testing efficiency and testing capabilities of the integrated sensing test system.

[0257] S1612, Exit test.

[0258] Each of the above steps has been explained in the foregoing content. Please refer to the foregoing explanation for details. They will not be repeated here.

[0259] In one exemplary embodiment, a method for switching between different test modes is provided, such as... Figure 17 As shown, the method includes:

[0260] S1701, When the integrated sensor test system is activated, it detects whether there is user access and sensing target. If no user access and no sensing target are detected, then step S1702 is executed; if user access and no sensing target are detected, then step S1703 is executed; if no user access and sensing target are detected, then step S1704 is executed; if user access and sensing target are detected, then step S1705 is executed.

[0261] S1702, the target test mode is determined to be beam test mode.

[0262] S1703, the target test mode is determined to be the communication test mode.

[0263] S1704, The target test mode is determined to be the perception test mode.

[0264] S1705, the target test mode is determined to be the integrated sensory test mode.

[0265] In this embodiment, when the sensory integration testing system performs automatic mode switching, the control device can detect the current user access status and the status of the sensing target of the sensory integration testing system, thereby determining which test mode is required at the current time. For example, if it is detected that there are no users accessing the sensory integration testing system and no sensing target, it means that the sensory integration testing system can enter beam testing, so the target test mode of the system at this time is beam testing mode; if it is detected that there are users accessing the sensory integration testing system and no sensing target, it means that the sensory integration testing system can enter communication testing, so the target test mode of the system at this time is communication testing mode; if it is detected that there are no users accessing the sensory integration testing system and a sensing target, it means that the sensory integration testing system can enter sensing testing, so the target test mode of the system at this time is sensing testing mode; if it is detected that there are users accessing the sensory integration testing system and a sensing target, it means that the sensory integration testing system can enter sensory integration testing, so the target test mode of the system at this time is sensory integration testing mode.

[0266] The method described in this application embodiment enables automatic switching between different test modes, allowing the integrated sensing and communication test system to perform multi-scenario switching tests, meeting the testing needs of various scenarios. Furthermore, during the switching process between different modes, different combinations of the control signal generator, spectrum analyzer, echo simulator, and channel simulator are used to construct different types of test subsystems, simulating different real-world scenarios for laboratory testing. This improves testing efficiency while reducing testing costs. It should also be noted that currently, if a communication channel model is used, it can only simulate and verify standard NLOS (non-line-of-sight) or LOS (line-of-sight) channel scenarios. However, sensing channels are subject to environmental clutter interference such as clouds, rain, sea, ground, and foliage. Therefore, the integrated sensing and communication test mode can simulate both wireless communication channels and sensing clutter channels to verify the system performance of both communication and sensing.

[0267] In addition to the methods described in all the foregoing embodiments, a sensory integration testing system applying the above methods is also provided. A schematic diagram of this sensory integration testing system can be found in the foregoing embodiments. Figure 1 The schematic diagram shown illustrates that the system includes: a signal generator, a spectrum analyzer, a phase shifter, an echo simulator, a channel simulator, and a control device. The control device is connected to the signal generator, spectrum analyzer, phase shifter, echo simulator, and channel simulator via a network-managed switch. The signal generator, spectrum analyzer, phase shifter, echo simulator, and channel simulator are connected via a synchronization link. The control device is also connected to an external base station. The control device is used to execute the aforementioned... Figures 2-17The method described in the examples.

[0268] The integrated sensory testing system and integrated sensory testing method involved in the embodiments of this application have been described in the foregoing content. For detailed descriptions, please refer to the foregoing content, and they will not be repeated here.

[0269] The above-described integrated sensing test system and method provide a laboratory-scale automated testing system for integrated sensing systems. This system can cover scenarios including low-altitude, airway, sea, and ground-to-air scenarios. The system includes automatically controllable devices such as a spectrum analyzer, signal generator, phase shifter, echo simulator, channel simulator, base station network side, and terminal side. These devices communicate via TCP / IP protocol and Socket communication interface. Using Python for software programming, the system can switch between four test modes: beamforming test mode, sensing test mode, communication test mode, and integrated sensing test mode, improving testing and verification efficiency. Furthermore, the communication sensing beamforming test judgment in the beamforming test mode and the TRIGER synchronous triggering process in the sensing test mode enrich multi-scenario testing while improving testing efficiency and accuracy. Compared to existing methods, this approach offers the following advantages: First, existing 5G NR systems focus solely on communication functions, resulting in a relatively simple test platform design with only one communication test mode. The current approach adds four new test modes: beamforming, sensing, integrated sensing, and communication, achieving automated coverage on a single platform. This enriches the test content and improves test efficiency. Second, the initial verification costs for integrated sensing scenarios in real-world settings are too high. Expensive drone rental or boat rental fees, as well as weather factors, all contribute to increased testing costs. This application not only utilizes existing equipment but also reduces testing costs.
