[0002] As one of the important application technologies of 5.5G (5G-A), the core feature of the integrated communication and perception (synaesthesia for short) technology is that it can perceive other objects in the detection area while communicating with the terminal. It has wide applications in low-altitude economy, industrial Internet and other fields. However, the traditional synaesthesia networking method usually only supports a single communication function or perception function. Due to the limitation of array isolation, a single module must use a pulse waveform to send and receive signals in the perception scene, resulting in the inability to perceive the target in the distance blind spot; although some modules adopt the form of array separation, the isolation between the arrays is still limited, and the detection distance is limited. In addition, site resources are limited. If the station-level perception range needs to be further improved, a new AAU (Active antenna unit, also known as the head end) must be replaced, which is not conducive to the reuse of existing equipment and limits the flexibility and scalability of the technology.

The character " / " generally indicates that the associated objects before and after are in an "or" relationship. In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0011] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0012] This application proposes a synaesthesia networking method and device, which solves the problems of limited perception performance, insufficient module scalability and low resource coordination efficiency in traditional solutions by using a joint communication and perception method of dual-end (two AAUs) or even multi-end (multiple AAUs). Specifically, the method dynamically configures the working modes (including communication mode and perception mode) of multiple active antenna units through a baseband processing unit, and flexibly switches the transmission mode, receiving mode or transmission and reception mode according to network requirements, thereby realizing efficient transmission and reception of perception signals and ensuring that there are no blind spots in perception. In the perception mode, multiple AAUs work together, and through a distributed networking method, the perception capability and coverage are significantly improved. At the same time, the centralized control of the baseband processing unit realizes the resource coordination and dynamic allocation of multiple AAUs, enhances the scalability and resource utilization efficiency of the module, ensures communication coverage and capacity, and has a wide range of application value in scenarios such as low-altitude economy.

[0013] The following is combined with Figures 1 to 13 The present application is described in detail.

[0014] Please refer to Figure 1 , Figure 1 It is a flow chart of the synaesthesia networking method of the present application. A synaesthesia networking method, the synaesthesia networking includes a baseband processing unit (BBU) and multiple active antenna units (AAUs) respectively connected to the BBU, wherein the multiple AAUs include at least one AAU as a transmitting module and at least one AAU as a receiving module, that is, the multiple AAUs can be divided into a transmitting module and a receiving module. The method includes a configuration stage (S110) and an application stage (S120): S110, in the configuration stage, the baseband processing unit configures the working mode of each active antenna unit according to the preset network requirements. The working mode includes a communication mode and a sensing mode. The sensing mode includes a transmission mode, a receiving mode, and a transmission and receiving mode.

[0015] The communication mode is used for information transmission between the terminal and the base station; the transmission mode means that an active antenna unit only acts as a transmission module to transmit sensing signals; the receiving mode means that an active antenna unit only acts as a receiving module to receive sensing signals; the transmission and reception mode means that an active antenna unit acts as both a transmission module and a receiving module.

[0016] Specifically, in traditional technologies, AAU is usually only used for communication, with limited perception functions, and a single working mode limits the functional expansion of the module and the flexibility of resource allocation, making it difficult to meet the needs of complex scenarios. The present application solves the above problems by dynamically configuring the working mode of AAU through BBU, and flexibly switching the communication mode or perception mode (including transmission mode, reception mode, and transmission and reception mode) according to network requirements. At the same time, the centralized control mechanism of BBU realizes the optimal allocation of resources for multiple AAUs, enhancing the flexibility and scalability of the system. Therefore, step S110 significantly improves the perception performance, realizes perception without blind spots through the transmission mode and the reception mode; enhances the module scalability, supports rapid function upgrades and scene adaptation; improves resource coordination efficiency, and optimizes the overall resource utilization of the system; at the same time, it has a high degree of flexibility and versatility, is suitable for a variety of scenarios integrating communication and perception, and has a wide range of application value.

[0017] S120, in the application stage, the baseband processing unit instructs the transmitting module to transmit signals, and instructs the receiving module to receive signals, and the receiving module transmits the received signals back to the baseband processing unit for signal processing; when switching modes, the baseband processing unit controls each active antenna unit to switch to the transmitting mode, receiving mode, or transmitting and receiving mode in the communication mode or the sensing mode.

[0018] Specifically, in traditional technologies, the working mode of AAU is fixed and difficult to adjust dynamically according to actual needs, resulting in low resource utilization efficiency, and it is difficult to optimize the communication and perception functions at the same time. The present application dynamically instructs the operation of the transmitting module and the receiving module in the application stage through the BBU, and controls the AAU to switch between the communication mode and the perception mode (including the transmitting mode, the receiving mode, and the transmitting and receiving mode) in real time to achieve efficient coordination of the communication and perception functions. At the same time, the BBU centrally processes the received signals, optimizes resource allocation and signal processing procedures, and improves the overall performance of the system. Therefore, step S120 achieves efficient coordination of communication and perception functions, improves resource utilization efficiency; through dynamic mode switching, the flexibility and adaptability of the system are enhanced; at the same time, the signal processing process is optimized, the perception accuracy and communication quality are improved, and it is suitable for a variety of complex scenarios and has a wide range of application value.

[0019] To summarize, this application solves the problems of limited perception performance, insufficient module scalability, and low resource coordination efficiency in traditional technologies through dynamic control in the configuration stage and the application stage, significantly improves the collaborative performance of perception and communication, enhances the flexibility and adaptability of the system, and is suitable for a variety of scenarios of integrated communication and perception, and has broad application value.

[0020] Please refer to Figure 2 , Figure 2 This is a schematic diagram of dual-end networking provided in Example 1 of the present application. Figure 2 It is to use a dual head end (such as AAU0 and AAU1) for networking, where AAU0 is used as a transmitting module (TX) and AAU1 is used as a receiving module (RX). AAU0 and AAU1 are connected to the BBU respectively through optical fiber, and inter-module communication is realized through RF line. This application realizes the continuous wave perception function through the dual module (transmitting module and receiving module) setting, eliminates the distance blind spot, and improves the isolation by adjusting the distance between the transmitting module and the receiving module, thereby enhancing the perception distance; when the perception distance exceeds the preset threshold, it can be expanded to multiple modules to form an AAU array, and the pulse wave is realized through array synthesis to further improve the detection capability. At the same time, this application supports TX / RX module mode switching. During the continuous wave test, the dual modules are set to TX and RX respectively and the corresponding modes can be switched; in the pulse mode, the two modules can be switched to TX or RX at the same time to increase the detection distance. Two modules (transmitting module and receiving module) are connected to a BBU, and the data is uniformly processed on the BBU side to realize the lightweight and miniaturization of the TX / RX unit; the modules can be assumed to have independent communication functions to ensure that the system can flexibly switch between communication and perception modes. This application significantly improves perception performance and system flexibility, is suitable for a variety of complex scenarios, and has broad application value.

[0021] In some embodiments, during the configuration phase, the baseband processing unit dynamically adjusts the working mode of each active antenna unit, configures some active antenna units to the communication mode, and configures some active antenna units to the sensing mode; the specific implementation process includes: In the frequency band allocation stage, when the number of available frequency band resources exceeds a preset threshold (that is, when the available frequency band resources are sufficient), the baseband processing unit allocates different frequency band resources to the communication mode and the perception mode; wherein, the communication mode occupies the first frequency band, the perception mode occupies the second frequency band, and a protection band is reserved between the first frequency band and the second frequency band to ensure that the frequency bands do not overlap, thereby avoiding interference between communication and perception; when the number of available frequency band resources is lower than the preset threshold, or the frequency band requirements of the communication mode and the perception mode cannot be met at the same time, the baseband processing unit uses a time division multiplexing mechanism to alternately allocate resources for the communication mode and the perception mode in the time domain to reduce the timing overhead of switching between communication and perception.

[0022] Among them, reserving a guard band between the first frequency band and the second frequency band means that when the communication mode and the perception mode occupy different frequency bands respectively, in order to avoid signal interference between the two, an unused frequency range (i.e., guard band) is set between the two frequency bands. This guard band plays an isolation role, ensuring that the signals of the communication mode and the perception mode do not overlap or interfere with each other, thereby ensuring the independence and stability of the communication and perception functions.

[0023] It is understandable that the frequency band allocation mechanism mainly solves the interference problem between communication and perception functions during frequency band resource allocation and co-frequency transmission, and optimizes resource utilization efficiency. By dynamically adjusting frequency band resources and time domain resources, the baseband processing unit not only improves the collaborative performance of communication and perception, but also enhances the flexibility and resource utilization efficiency of the system, which is suitable for multi-functional needs in complex scenarios.

[0024] Please refer to Figure 3 , Figure 3 This is a schematic diagram of the transmission time slot and receiving time slot of the traditional solution. In the traditional solution, pulse waves are used to transmit and receive signals. During the time period of the transmission signal (T1 is the transmission time slot), the receiving channel is closed and the echo signal in this time period cannot be received. This working mode causes a blind spot in distance. The blind spot range is C*T1 / 2 (where C is the speed of light), that is, the distance range that cannot be detected during the signal transmission. The existence of this blind spot limits the perception ability of the traditional solution and cannot achieve a continuous detection effect without blind spots.

[0025] Please refer to Figure 4 , Figure 4 It is a schematic diagram of the transmission time slot and the receiving time slot provided in the embodiment of the present application. The present application solves the detection blind spot problem existing in the traditional solution by adopting a dual module or a plurality of modules. Dual modules, such as two AAUs, are respectively used as a transmission module (TX) and a receiving module (RX), which are connected to the BBU through optical fiber or radio frequency line. The transmission module continuously transmits signals, and the receiving module continuously receives echo signals, thereby avoiding the detection blind spots in the traditional solution. Multiple modules, such as multiple AAUs, form an array and realize more complex perception functions through collaborative work. For example, some AAUs are responsible for transmitting signals, and some AAUs are responsible for receiving signals, and long-distance or high-precision detection is achieved through array synthesis.

[0026] Taking the dual modules as an example, one module is used as a transmitting module (TX) to continuously transmit signals, and the other module is used as a receiving module (RX) to continuously receive echo signals. Since the transmitting and receiving modules work at the same time, the receiving module will not be shut down due to the transmitting time slot, so all echo signals can be received, avoiding the detection blind area (i.e., the distance blind area of ​​C*T1 / 2) caused by the transmitting time slot in the traditional solution. This design of the present application achieves a continuous detection effect without blind spots, significantly improving the system's perception performance and detection accuracy.

[0027] In some embodiments, for the transmission mode, the transmission module transmits a perception signal of a preset frequency and waveform; for the receiving mode, the perception signal received by the receiving module includes information about the trajectory, speed, and distance of the target, and transmits the information back to the baseband processing unit; for the transmission and reception mode, the active antenna unit acts as a transmission module and a reception module at the same time, including: In the transmission phase, the active antenna unit transmits the sensing signal; In the receiving stage, the active antenna unit receives the reflected signal and eliminates the interference between the transmitted signal and the received signal through a preset digital signal processing algorithm, which specifically includes: introducing a feedback channel in the transmitting module to directly couple a part of the transmitted signal to the receiving module as a reference signal; generating a reference copy of the transmitted signal based on the reference signal provided by the feedback channel; matching the reference copy of the transmitted signal with the received signal in phase and amplitude; and removing the interference component of the transmitted signal from the received signal through subtraction operation to achieve isolation between transmission and reception.

[0028] The design of the present application effectively eliminates the interference of the transmitted signal on the received signal through the feedback channel and digital signal processing algorithm, achieves high isolation between transmission and reception, significantly improves the system's perception accuracy and anti-interference ability, and is suitable for continuous blind-spot detection needs in complex scenarios.

[0029] Please refer to Figure 5 , Figure 5 is a schematic diagram of a feedback channel provided in an embodiment of the present application. The multiple active antenna units include a first active antenna unit (such as AAU0) as a transmitting module and a second active antenna unit (such as AAU1) as a receiving module. The specific implementation process of the feedback channel includes: In the first active antenna unit, the transmission signal is transmitted to the transmission antenna array through the transmission link, and part of the transmission signal is coupled to the external RF interface through the coupling feeder; in the second active antenna unit, the external RF interface receives the coupled signal from the first active antenna unit and transmits the signal to the receiving link through the switch; in the receiving link, the coupled signal is converted into a digital signal through an analog-to-digital converter and transmitted to the external optical port. The digital signal generated based on the coupled signal is used as a reference signal of the feedback channel to generate a reference copy of the transmission signal.

[0030] In some embodiments, in the application stage, the baseband processing unit performs unified processing on the received signals, including: Demodulate the communication signal to extract information between the terminal and the base station; and The perception signal is processed to extract information about the target’s trajectory, speed, and distance.

[0031] Specifically, in the application stage, the baseband processing unit performs unified processing on the received signals, including: (1) R (Range, distance) spectrum segmentation method: Demodulate the communication signal and extract the information between the terminal and the base station; The perception signal is processed to extract the target's trajectory and velocity information based on the distance information reported by the AAU and the BBU's MTI (Moving Target Indication) clutter suppression, V (Velocity) spectrum processing, CFAR (Constant False Alarm Rate) processing, angle spectrum estimation, and trajectory processing.

[0032] (2) V spectrum segmentation method: Demodulate the communication signal and extract the information between the terminal and the base station; The perception signal is processed to extract the target's trajectory information based on the distance and speed information reported by the AAU and combined with the BBU's MTI clutter suppression, CFAR processing, angle spectrum estimation, and trajectory processing.

[0033] Please refer to Figure 6 , Figure 6 This is a schematic diagram of data processing provided by an embodiment of the present application. In the entire AAU (e.g., AAU0 / AAU1 / … / AAUn), only ADC (analog-to-digital conversion) and R spectrum processing are performed, which can greatly reduce the resource consumption of the AAU. When the modules are networked, they can be adapted in advance without the need for additional instructions from the BBU, thereby achieving a lightweight design of the AAU, saving costs and power consumption, and facilitating system networking.

[0034] When the resources on the AAU are sufficient, the split point can be flexibly adjusted according to demand. The BBU is adapted through the fronthaul interface, as follows: R spectrum segmentation: If the segmentation point is at the R spectrum, the AAU only reports the distance information, and other processing (such as MTI clutter suppression, V spectrum processing, CFAR processing, angle spectrum estimation, and trajectory processing) is completed by the BBU by default.

[0035] V spectrum segmentation: If the segmentation point is at the V spectrum, the AAU reports the distance and speed information, and other processing is completed by the BBU by default.

[0036] Through this flexible segmentation method, the BBU can dynamically adjust the backend processing capabilities according to the information reported by the AAU, thereby achieving efficient use of resources and optimizing system performance.

[0037] The following is an example to illustrate the implementation process of the synaesthesia networking method: Step 1: When building a synaesthesia network, after completing module deployment, configure it according to the preset connection relationship to ensure that the connection between the transmitting module (such as AAU0) and the receiving module (such as AAU1) meets the design requirements of the feedback channel.

[0038] Step 2: The BBU instructs the transmitting module (such as AAU0) to transmit a sensing signal with a preset frequency, a specific waveform (such as signal A), and a specific beam direction. The sensing signal is transmitted to the transmitting antenna array through the transmitting link, and part of the transmitting signal is coupled to the external RF interface through the coupling feeder as a reference signal for the feedback channel.

[0039] Step 3: BBU instructs the receiving module (such as AAU1) to receive the sampled data and obtain signal B. The receiving module (such as AAU1) receives the coupled signal from the transmitting module (such as AAU0) through the external RF interface and transmits the signal to the receiving link through the switch.

[0040] In the receiving link, the coupled signal is converted into a digital signal by an analog-to-digital converter and preprocessed to generate a preprocessed signal B'. This signal B' is used as a reference copy of the feedback channel for subsequent interference elimination.

[0041] Step 4: BBU instructs the transmitting module (such as AAU0) and the receiving module (such as AAU1) to perform normal beam scanning detection. The receiving module (such as AAU1) acquires signal C in real time, matches the phase and amplitude of signal C with the preprocessed signal B' through the preset digital signal processing algorithm, and removes the interference component of the transmitting signal from the received signal through subtraction operation. This method, combined with the chip sampling capability, can improve the isolation between modules, for example, by 5~10dB.

[0042] Step 5: Under the preset frequency, waveform and beam, the transmitting module and receiving module (such as AAU0 and AAU1) work normally and report the detection information (such as the target's trajectory, speed, and distance) to the BBU. The BBU instructs the transmitting module and receiving module (such as AAU0 and AAU1) to scan the next beam based on the detection results to continuously optimize the detection effect.

[0043] Please refer to Figure 7 , Figure 7 1 is a structural diagram of the synaesthesia network provided in an embodiment of the present application. AAU0 101 and AAU1 102 are installed on a base 104, so that AAU0 101 and AAU1 102 are fixed to the ground through the base 104. AAU0 101 and AAU1 102 are both provided with a power supply port 105 and an optical fiber port 106. AAU0 101 and AAU1 102 are respectively connected to the BBU through their respective optical fiber ports 106 for joint data processing. AAU0 101 and AAU1 102 can adjust the scanning range of communication perception through the bracket 103, so that AAU0 101 and AAU1 102 face different directions, thereby realizing flexible coverage requirements.

[0044] In addition, the synaesthesia networking device of the present application is not limited to ground installation, but also supports pole installation. By designing different structural parts for adaptation, a variety of installation requirements can be met.

[0045] In some embodiments, according to a preset isolation requirement, the spacing between active antenna units is adjusted through a mechanical structure so that it meets a preset isolation threshold.

[0046] For example, Figure 7 The bracket 103 is a mechanical structure that can adjust the distance between AAU0 101 and AAU1 102. When networking, the distance between AAU0 and AAU1 can be dynamically adjusted according to the needs. Under the communication networking requirements (modules operate independently), the distance can be left unchanged; under the perception networking requirements, the bracket 103 can be used to increase the distance to improve the isolation.

[0047] In addition to physical spacing adjustment, high isolation can also be achieved through digital signal processing compensation. Figure 5As shown, AAU0 serves as a transmitting module and AAU1 serves as a receiving module. The relevant data of the transmitting module is transmitted to the receiving module through the coupling feeder and the RF interface. Before the sensing scene works, a targetless scene test is first performed. AAU1 collects the transmission data of AAU0 through the switch, which is recorded as A. During the actual detection, AAU1 collects data B and processes the data through an algorithm. It pre-distorts data A in advance to eliminate the influence of interference signals, thereby improving AAU1's anti-interference ability to AAU0's transmission signal and achieving high isolation. This application combines mechanical structure adjustment and digital signal processing, which can more flexibly and efficiently meet the isolation requirements in different scenarios.

[0048] In some embodiments, the system operates in pulse mode, where two AAUs can be used as transmitting modules or receiving modules at the same time. In the transmitting phase, the two AAUs transmit pulse signals at the same time, and ensure the phase consistency of the transmitted signals through a time synchronization mechanism (such as using the same clock source and a preset calibration algorithm); in the receiving phase, the two AAUs receive reflected signals at the same time, and ensure the phase consistency of the received signals through the same time synchronization mechanism. The role of this design is to enhance the detection distance and accuracy of the signal through phase consistency, while improving the anti-interference ability and reliability of the system, and is suitable for scenarios requiring high-precision detection.

[0049] Please refer to Figure 8 , Figure 8 It is a logical diagram of the synaesthesia network provided in Example 2 of the present application. The entire system includes multiple AAUs, including M AAUs as transmitting modules and N AAUs as receiving modules. For example, the transmitting module includes AAU0 (TX1), AAU1 (TX2), ..., AAUm (TXm), and the receiving module includes AAUx (RX1), AAUy (RX2), ..., AAUn (RXn). All AAUs are connected to the BBU through the fronthaul interface, and the data is uniformly aggregated to the BBU for processing. The deployment method of the transmitting module (TX) and the receiving module (RX) is flexible, and can be distributed at intervals or arranged adjacently, and the system does not restrict this. The BBU dynamically manages the working mode switching of AAU0~AAUm (transmitting module) and AAUx~AAUn (receiving module) by sending control commands to achieve large-scale, high-precision detection and perception functions. This flexible modular design can adapt to the needs of different application scenarios and significantly improve the overall performance of the system.

[0050] In some embodiments, when the sensing distance exceeds a preset threshold, the baseband processing unit expands the multiple active antenna units into an antenna array, including: Arranging multiple active antenna units according to a desired spatial layout to form an antenna array; The transmission signals of multiple active antenna units are synthesized through a preset beamforming algorithm, including: phase weighting and amplitude weighting of the transmission signals of multiple active antenna units to form a high-power pulse wave to achieve long-distance detection.

[0051] That is to say, when it is necessary to achieve long-distance perception, the BBU will combine multiple AAUs into an antenna array. The spatial layout can be, for example, linear arrangement, planar arrangement, circular array or three-dimensional array. Linear arrangement means that multiple AAUs are arranged in a straight line to form a linear antenna array; planar arrangement means that multiple antenna units are arranged in a two-dimensional plane (such as a rectangle or a circle) to form a planar antenna array. Then, the BBU synthesizes the transmission signals of these AAUs through a preset beamforming algorithm, including weighted processing of the phase and amplitude of the signal, thereby generating a high-power pulse wave to achieve longer-distance detection capabilities.

[0052] In some embodiments, multiple active antenna units include a sensing unit, a communication unit, and a synaesthesia unit; wherein the sensing unit refers to a set of active antenna units for sensing function, and its working mode is sensing mode; the communication unit refers to a set of active antenna units for communication function, and its working mode is communication mode; the synaesthesia unit refers to a set of active antenna units having both communication and sensing functions, and its working mode is dynamic switching of communication mode and sensing mode or simultaneous operation.

[0053] The following is another example to illustrate the implementation process of the synaesthesia networking method: Step 1: Plan the network and deploy AAU based on the performance requirements of the scenario (such as sensing coverage distance, communication capacity, etc.). For example: If the perception coverage distance of a certain area is far, multiple AAUs are deployed in a centralized manner as perception units; if the communication capacity requirement of a certain area is high or the coverage distance is short, multiple AAUs are deployed in a separate manner as communication units, perception units or synaesthesia units.

[0054] Step 2: The BBU configures the following information for all AAUs through the fronthaul interface channel: Working modes: communication mode, perception mode-Tx (i.e. transmission mode), perception mode-Rx (i.e. reception mode), perception mode-Tx&Rx (i.e. transmission and reception mode), synaesthesia mode (communication mode and perception mode, referred to as synaesthesia mode)-Tx, synaesthesia mode-Rx, synaesthesia mode-Tx&Rx; Resource allocation: communication and perception frequency domain location, time domain location; Perception waveform: continuous wave, pulse wave, and pulse sending time (related to the distance during network planning).

[0055] Step three: Each AAU completes signal transmission and reception in the mode indicated by the BBU, and transmits the received signal back to the BBU; the BBU completes communication and perception signal processing according to the configured AAU status information, realizes communication signal demodulation (information transmission between the terminal and the base station) and perception signal processing (obtaining the trajectory of the target).

[0056] Please refer to Fig. 9 , Fig. 9 It is a schematic diagram of the transmitting time slot and receiving time slot provided in the second embodiment of the present application. When multiple AAUs (such as AAU0, AAU1, and AAU2) are jointly networked, the system can dynamically allocate time slot resources according to the differences in detection targets in different time slots and different areas, thereby ensuring that the detection effect of the entire network is optimal. This flexible time slot allocation mechanism can not only optimize resource utilization, but also significantly improve detection capabilities, making it more advantageous than traditional pulse radars. For example, in a certain time slot, the system can specify AAU0 as the transmitting module, AAU1 and AAU2 as receiving modules; in another time slot, the system can switch to AAU1 as the transmitting module, and AAU0 and AAU2 as receiving modules. Through this dynamic adjustment, the system can capture target information more accurately and achieve efficient and flexible detection.

[0057] In some embodiments, when performing mode switching, the baseband processing unit controls each active antenna unit to switch to a transmission mode, a reception mode, or a transmission and reception mode in a communication mode or a sensing mode, including: According to the networking requirements of the system, multiple active antenna units are set to sensing mode; According to the fronthaul interface requirements of the baseband processing unit, some active antenna units are set as transmitting modules in some time slots, and the remaining active antenna units are always used as receiving modules; The baseband processing unit sets the frequency points for the multiple active antenna units and instructs them to perform polling scanning according to the preset beam sequence; In a preset time slot, the baseband processing unit instructs at least one active antenna unit to act as a transmitting module and the remaining active antenna units to act as receiving modules; According to the results reported by the active antenna unit, if the target disappears or cannot be tracked, the baseband processing unit dynamically adjusts the allocation of the transmitting module and the receiving module to re-evaluate the detection effect.

[0058] It is understandable that the purpose of mode setting, resource allocation, and dynamic adjustment is to enable rapid adjustment of strategies in different scenarios (such as when the target disappears or cannot be tracked) to improve the overall performance and reliability of the system.

[0059] In some embodiments, the baseband processing unit dynamically adjusts the working mode of the active antenna unit according to the result reported by the active antenna unit, including: Determine the tracking status of the target based on the results reported by the active antenna unit; If the result does not reach the preset threshold, the baseband processing unit dynamically adjusts the working mode of the active antenna unit, specifically including: Dynamically adjust the allocation of transmit modules and receive modules; and Reconfigure the operating mode of the active antenna unit to optimize target tracking.

[0060] It is understandable that the BBU dynamically adjusts the AAU working mode (such as the allocation of the transmitting module and the receiving module) according to the results reported by the AAU to optimize the target tracking effect. When the result does not reach the preset threshold, the BBU will reconfigure the AAU working mode to improve the accuracy and stability of target tracking.

[0061] Please refer to Fig.10 , Fig.10 Schematic diagram of the transmission beam provided in the second embodiment of the present application. The networking process includes the following steps: Step 1: According to the system networking requirements, configure AAU0, AAU1 and AAU2 to sensing mode.

[0062] Step 2: According to the fronthaul interface requirements of the BBU, the transmitting modules of some time slots of AAU0 and AAU1 are configured, and AAU2 is always configured as a receiving module; the BBU configures the frequencies of AAU0, AAU1 and AAU2.

[0063] Step 3: BBU instructs AAU0, AAU1 and AAU2 to scan beams in a certain order, such as spatial beams A, B, and C.

[0064] Step 4: According to the preset beam sequence, the BBU instructs three AAUs (i.e., AAU0, AAU1, and AAU2) to perform polling scans. For example, in time slot 1, AAU0 acts as a transmitting module, and AAU1 and AAU2 act as receiving modules; in time slot 2, AAU0 and AAU2 act as receiving modules, and AAU1 acts as a transmitting module.

[0065] Step 5: According to the results reported by each AAU, evaluate the tracking effect of the current network target. If the target disappears or cannot be tracked, the BBU indicates that AAU1 is used as the transmitting module, and AAU0 and AAU2 are used as receiving modules.

[0066] Step 6: The BBU flexibly adjusts the mode between AAUs according to the results of the AAU scanning.

[0067] It is understandable that through the signaling control of the BBU, each head end can flexibly switch the working mode (such as transmission mode, reception mode or transmission and reception mode) according to the network location, realizing the joint communication and perception function of multiple heads. This flexible switching mechanism can not only adjust the TX / RX mode of the module, but also greatly improve the network capacity, meet the communication and perception needs in different scenarios, and thus optimize the overall network performance.

[0068] Please refer to Fig.11 , Fig.11 This is one of the timing diagrams of the synaesthesia switching provided in the embodiment of the present application. When performing mode switching, the baseband processing unit controls each active antenna unit to switch to the transmission mode, the receiving mode, or the transmission and receiving mode in the communication mode or the perception mode, including: At a first moment (T1), the baseband processing unit (BBU) allocates a first frequency band (F1) to the communication unit and a second frequency band (F2) to the sensing unit.

[0069] At the second moment (T2), the perception unit detects the target (such as a drone) and the communication unit establishes communication with the target.

[0070] At the third moment (T3), the sensing unit reports the detected target position to the baseband processing unit, and the communication unit reports the communication result to the baseband processing unit.

[0071] It can be understood that when switching modes, the BBU flexibly controls the working mode of each AAU (such as the transmission mode, receiving mode, or transmission and receiving mode in the communication mode or perception mode) to achieve the parallel development of communication and perception functions. Specifically, at the first moment, the BBU allocates the first frequency band to the communication unit and the second frequency band to the perception unit, and ensures that the communication and perception functions do not interfere with each other and are carried out simultaneously through frequency isolation. At the second moment, after the perception unit detects the target, the communication unit establishes communication with the target to achieve seamless connection from perception to communication. At the third moment, the perception unit reports the detected target position to the BBU, and the communication unit reports the communication results to the BBU. The BBU dynamically adjusts the working mode of the AAU based on this information to further optimize the communication and perception effects.

[0072] Through this time-sharing and frequency-sharing mechanism, the BBU can efficiently coordinate communication and perception functions, reduce the timing overhead of mode switching, and realize communication and perception functions at the same time, thereby improving the overall performance of the network.

[0073] Please refer to Fig.12 , Fig.12 This is the second timing diagram of the synaesthesia switching provided in the embodiment of the present application. When performing mode switching, the baseband processing unit controls each active antenna unit to switch to the transmission mode, the receiving mode, or the transmission and receiving mode in the communication mode or the perception mode, including: At a first moment (T1), a baseband processing unit (BBU) allocates a first frequency band (F1) to the synaesthesia unit; At the second moment (T2), the synaesthesia unit detects the target (e.g., a drone); At the third moment (T3), the synaesthesia unit reports the detected target position to the baseband processing unit; At the fourth moment (T4), the synaesthesia unit establishes communication with the target; At the fifth moment (T5), the synaesthesia unit reports the communication result to the baseband processing unit.

[0074] It is understandable that when switching modes, the BBU controls the same group of AAUs to flexibly switch between communication mode and perception mode through a time-sharing mechanism, thereby realizing communication and perception functions in scenarios with a limited number of modules. Specifically, at the first moment, the BBU allocates the first frequency band to the synesthesia unit to ensure that communication and perception tasks are carried out in time at the same frequency point; at the second moment, the synesthesia unit detects the target in the perception mode and completes the preliminary acquisition of the target information; at the third moment, the synesthesia unit reports the detected target position to the BBU to provide data support for the subsequent communication establishment; at the fourth moment, the synesthesia unit switches to the communication mode and establishes communication with the target, realizing seamless connection from perception to communication; at the fifth moment, the synesthesia unit reports the communication results to the BBU, and the BBU further optimizes the network configuration based on the reported information.

[0075] Through this time-division multiplexing mechanism, the BBU can efficiently utilize limited module resources and realize the alternating execution of communication and perception functions at the same frequency, which not only reduces hardware costs but also improves the flexibility and adaptability of the network, and is suitable for small-area coverage scenarios.

[0076] It should be noted that the synaesthesia networking method provided by this application has wide applicability and can be flexibly applied to various general wireless communication scenarios, including but not limited to typical scenarios such as 5G communication millimeter wave equipment and satellite communication equipment. In 5G millimeter wave communication, the system meets the communication requirements of high bandwidth and low latency through flexible mode switching and dynamic resource allocation; in satellite communication, the system optimizes the working mode of active antenna units to adapt to complex environments and improve communication quality and perception capabilities.
