Description

Technical Field

[0001] This application relates to the field of communication technology, specifically to a communication method, apparatus, program product, and storage medium. Background Technology

[0002] With the development of target perception technology, it has been applied to various fields such as autonomous driving and security monitoring. Target perception technology refers to the technique of sending perception signals to a perceived area and then analyzing the received perception signals to determine whether a target exists within the perceived area.

[0003] Currently, in situations where there are strong reflectors or insufficient isolation between the receiver and receiver within the sensing area, the received sensing signals may be abnormal, which will lead to a decrease in the target detection rate and an increase in the false alarm rate. Summary of the Invention

[0004] This application provides a communication method, apparatus, program product, and storage medium to reduce the false alarm rate when sensing and receiving abnormal signals.

[0005] In view of this, in a first aspect, embodiments of this application provide a communication method, the method comprising: sending a first sensing result, the first sensing result carrying abnormal information, the abnormal information being used to indicate that a first sensing received signal corresponding to the first sensing result is abnormal; and receiving an abnormality response strategy, the abnormality response strategy being associated with the abnormal information.

[0006] In the method provided by the embodiments of this application, abnormal information indicating that there is an abnormality in the received sensing signal is sent along with the sensing result in a timely manner. In this way, the abnormality response strategy associated with the abnormality information can be received in a timely manner, so that corresponding processing can be carried out in a timely manner based on the abnormality response strategy, such as distrusting the sensing result, or adjusting the sensing signal to reacquire the sensing result, etc., thereby reducing the false alarm rate in the case of abnormal received sensing signal.

[0007] In conjunction with the first aspect, in one possible implementation of the first aspect, the anomaly information includes the anomaly type of the first sensed received signal. This means that the specific anomaly type of the sensed received signal is sent along with the sensing result, thereby enabling the reception of anomaly response strategies associated with the specific anomaly type—that is, receiving more targeted anomaly response strategies. Based on these more targeted anomaly response strategies, the false alarm rate in the event of anomalies in the sensed received signal can be further reduced.

[0008] In conjunction with the first aspect, in one possible implementation of the first aspect, the anomaly information includes an anomaly type code, which indicates the anomaly type of the first sensed received signal. By using an anomaly type code to indicate the anomaly type of the sensed received signal, the amount of information carried can be reduced, enabling timely reporting of sensing results while minimizing communication resources.

[0009] In conjunction with the first aspect, in one possible implementation of the first aspect, the anomaly information further includes an anomaly confidence probability, which indicates the confidence probability of an anomaly type. Combining the anomaly confidence probability and the anomaly type in this way yields a more targeted anomaly response strategy, which can further reduce the false alarm rate in cases of perceived signal anomalies.

[0010] In conjunction with the first aspect, in one possible implementation of the first aspect, the anomaly response strategy includes: a first indication message, which indicates whether to disable the sensing function. This allows for timely disabling of the sensing function when the sensing results are not trusted in cases of abnormal sensing signal reception, thereby reducing the false alarm rate and sensing overhead.

[0011] In conjunction with the first aspect, in one possible implementation of the first aspect, the anomaly response strategy includes: second indication information, which is used to instruct adjustments to the first sensing signal corresponding to the first sensing result. In this way, when the received sensing signal is abnormal, the sensing signal can be adjusted in a timely manner, thereby enabling the subsequent acquisition of a more accurate sensing result, thus reducing the impact of abnormal sensing signal reception and lowering the false alarm rate.

[0012] In conjunction with the first aspect, in one possible implementation of the first aspect, the second indication information is specifically used to indicate at least one of the following: switching the waveform of the first sensing signal, adjusting the transmission power of the first sensing signal, adjusting the frequency of the first sensing signal, adjusting the target detection threshold of the first sensing signal, adjusting the start position of the frequency domain resource block of the first sensing signal, adjusting the length of the frequency domain resource block, adjusting the time domain time slot of the first sensing signal, or adjusting the time domain symbol of the first sensing signal. This allows for the acquisition of specific anomaly response strategies, enabling targeted adjustments to the first sensing information, thereby subsequently acquiring relatively normal sensing reception signals and reducing the false alarm rate.

[0013] In conjunction with the first aspect, in one possible implementation of the first aspect, the method further includes: adjusting the first sensing signal based on an anomaly response strategy to obtain a second sensing signal; sending the second sensing signal; receiving a second sensing reception signal corresponding to the second sensing signal; analyzing the second sensing reception signal to obtain a second sensing result; and sending the second sensing result. This allows for targeted adjustment of the first sensing signal based on the anomaly response strategy, thereby obtaining more accurate sensing results and reducing the false alarm rate in cases of abnormal sensing reception signals.

[0014] In conjunction with the first aspect, in one possible implementation of the first aspect, before sending the first sensing result, the method further includes: sending a first sensing signal; receiving a first sensing reception signal corresponding to the first sensing signal; and analyzing the first sensing reception signal to determine that the first sensing reception signal is abnormal. This allows for timely reporting of abnormal information when an anomaly is detected in the sensing reception signal.

[0015] Secondly, embodiments of this application provide a communication method, the method comprising: receiving a first sensing result, the first sensing result carrying abnormal information, the abnormal information being used to indicate that there is an abnormality in a first sensing received signal corresponding to the first sensing result; and sending an abnormality response strategy, the abnormality response strategy being associated with the abnormal information.

[0016] In the method provided by the embodiments of this application, abnormal information indicating that there is an abnormality in the sensing and receiving signal is received is received. In this way, the abnormal response strategy associated with the abnormal information can be determined in a timely manner and the abnormal response strategy can be sent in a timely manner so that corresponding processing can be carried out in a timely manner based on the abnormal response strategy, such as distrusting the sensing result or adjusting the sensing signal to reacquire the sensing result, etc., thereby reducing the false alarm rate in the case of abnormal sensing and receiving signal.

[0017] In conjunction with the second aspect, in one possible implementation of the second aspect, the method further includes: determining an anomaly response strategy based on anomaly information. This enables the determination of an anomaly response strategy for the first sensed received signal, reducing the false alarm rate in cases of anomalies in the sensed received signal.

[0018] In conjunction with the second aspect, in one possible implementation, the anomaly information includes an anomaly type code, which indicates the anomaly type of the first sensed received signal. This means that the anomaly type code, indicating the anomaly type, is sent along with the sensing result, thereby enabling the reception of anomaly response strategies associated with specific anomaly types—that is, receiving more targeted anomaly response strategies. Based on these more targeted strategies, the false alarm rate in cases of anomaly in the sensed received signal can be further reduced. Furthermore, using an anomaly type code to indicate the anomaly type of the sensed received signal reduces the amount of information carried, enabling timely reporting of sensing results while minimizing communication resources.

[0019] In conjunction with the second aspect, in one possible implementation of the second aspect, the anomaly response strategy includes: a first indication message, which indicates whether to disable the sensing function. This allows for timely disabling of the sensing function when the sensing results are not trusted due to abnormal sensing signal reception, thereby reducing the false alarm rate and sensing overhead in cases of abnormal sensing signal reception.

[0020] In conjunction with the second aspect, in one possible implementation of the second aspect, the anomaly response strategy includes: second indication information, which is used to instruct adjustment of the first sensing signal corresponding to the first sensing result. In this way, in the event of an anomaly in the received sensing signal, the sensing signal can be adjusted in a timely manner, thereby enabling the subsequent acquisition of a more accurate sensing result, thus reducing the impact of the anomaly in the received sensing signal and lowering the false alarm rate.

[0021] In conjunction with the second aspect, in one possible implementation of the second aspect, the method further includes: receiving a second sensing result, which is a sensing result obtained after adjustment based on the anomaly response strategy. This allows for the receipt of an anomaly sensing result obtained after targeted adjustments based on the anomaly response strategy, resulting in a more accurate sensing result and thus reducing the false alarm rate in cases of abnormal received signals.

It should be noted that in the description of the embodiments of this application, terms such as "first" and "second" are used only for the purpose of distinguishing descriptions and should not be construed as indicating or implying relative importance, nor should they be construed as indicating or implying order.

[0051] The embodiments of this application can be applied to communication systems, including second-generation (2G), third-generation (3G), and fourth-generation (4G) communication systems; long-term evolution (LTE) systems; fifth-generation (5G) communication systems; hybrid LTE / 5G architectures; 5G New Radio (5G NR) systems; and other new communication systems emerging in future communication developments.

The embodiments of this application can also be applied to satellite communication systems, wherein the satellite communication system can be integrated with the aforementioned communication systems.

[0052] A communication system may include a first device and a second device. The first device may be a network-side device used to provide network communication functions; in some cases, it is also called a network device or network element. A network device is typically a base station (including functional units of a base station, or a combination of functional units of base stations) or a core network unit. The core network unit may be a functional unit within the core network, including but not limited to Access and Mobility Management Function (AMF) units or Session Management Function (SMF) units. The second device may be a device accessing the network, typically a terminal. In a communication system, network devices and terminal devices can be connected via an air interface. An example of a communication system is shown below. Figure 1 As shown, Figure 1 It includes base station 1 and terminal 2.

[0053] In the embodiments provided in this application, the network device is used to receive uplink signals from the terminal, send downlink signals to the terminal, or receive echo signals of signals sent by itself, etc. The network device can be a device in a wireless network. For example, the network device can be a radio access network (RAN) node (or device) that connects the terminal to the wireless network, and can also be called a base station. The base station can be any device with wireless transceiver capabilities, including but not limited to: evolved base stations (NodeB or eNB or e-NodeB) in LTE, base stations (gNodeB or gNB) or transmission receiving points / transmission reception points (TRPs) in new radio (NR), base stations evolved later in 3GPP, access nodes in Wi-Fi systems, wireless relay nodes, wireless backhaul nodes, etc. The base station can be: macro base station, micro base station, pico base station, small cell, relay station, or balloon station, etc. The base station can contain one or more co-located or non-co-located transmission reception points (TRPs). Base stations can also be radio controllers, centralized units (CUs), and / or distributed units (DUs) in cloud radio access network (CRAN) scenarios. This allows multiple network functional entities to implement some functions of the radio access network equipment. These network functional entities can be network elements within hardware devices, software functions running on dedicated hardware, or virtualized functions instantiated on a platform (e.g., a cloud platform). Similarly, in vehicle-to-everything (V2X) technology, network devices can be roadside units (RSUs). Multiple network devices in a communication system can be base stations of the same type or different types. Base stations can communicate directly with terminals or via relay stations. Terminals can communicate with multiple base stations using different technologies; for example, a terminal can communicate with a base station supporting LTE networks, a base station supporting 5G networks, or even have dual connections with both LTE and 5G base stations.

[0054] The network device in this application embodiment can also be a device with sensing capabilities. This device can transmit sensing signals, receive and process sensing signals reflected by targets in the environment. The communication device used to implement the network device function in this application embodiment can be a network device, a network device with base station functionality, or a device that supports the network device in implementing this function, such as a chip system, which can be installed in the network device, etc.

[0055] In the embodiments provided in this application, a terminal is a user-side entity used to receive or transmit signals. It is used to send uplink signals to network devices, receive downlink signals from network devices, send signals to another terminal device, receive signals from another terminal device, or receive echo signals of its own transmitted signals, etc. Terminals are used to connect people, things, and machines, and can be widely used in various scenarios, such as: cellular communication, device-to-device (D2D) communication, V2X communication, machine-to-machine / machine-type communications (M2M / MTC) communication, Internet of Things (IoT), virtual reality (VR), augmented reality (AR), industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, smart cities, drones, robots, and other scenarios. Terminals can take many forms, such as mobile phones, tablets, computers with wireless transceiver capabilities, handheld terminals in cellular communication, communication devices in D2D, IoT devices in MTC, virtual reality (VR) terminal devices, AR terminal devices, wireless terminals in industrial control, vehicle-mounted terminal devices, wireless terminals in self-driving cars, wireless terminals in remote medical care, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, wearable terminal devices, and so on.

[0056] The embodiments of this application can be applied to Open Radio Access Network (RAN) scenarios. Please refer to [link / reference]. Figure 2 This is a schematic diagram of another communication system provided in an embodiment of this application. Figure 2The communication system may include RAN 100 and core network 200; optionally, the communication system may also include Internet 300. RAN 100 includes at least one RAN node (e.g., Figure 2 110a and 110b, collectively referred to as 110, may also include at least one terminal (such as...). Figure 2 RAN 100, denoted as RAN 120a-120j, is collectively referred to as RAN 120. RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment. Figure 2 (Not shown in the image). Terminal 120 connects wirelessly to RAN node 110, and RAN node 110 connects wirelessly or via a wired connection to core network 200. The core network equipment in core network 200 and RAN node 110 in RAN 100 can be independent physical devices, or they can be the same physical device integrating the logical functions of core network equipment and RAN nodes. Terminals can connect to each other, and RAN nodes can connect to each other, via wired or wireless connections. Figure 2 RAN node 110 can be a CU, DU, CU (control plane, CP), CU (user plane, UP), or radio unit (RU), etc. CU and DU can be configured separately or included in the same network element, such as a baseband unit (BBU). RU can be included in radio equipment or radio units, such as in a remote radio unit (RRU), active antenna unit (AAU), or remote radio head (RRH).

[0057] To more clearly illustrate the technical solutions of the embodiments of this application, the relevant concepts involved in the embodiments of this application are explained below.

[0058] 1) Perception: This refers to detecting parameters of targets in the physical environment, such as the target's position and velocity. It can be understood as a radar detection system detecting targets by emitting electromagnetic waves and analyzing signals reflected from objects. Perception can also be called detection.

[0059] 2) Target: can be any tangible object in the environment that can reflect electromagnetic waves, such as mountains, forests, or buildings, and can also include mobile objects such as vehicles, drones, pedestrians, and terminal devices. The target can also be referred to as the perceived target, the detected target, the perceived object, the detected object, or the perceived device, etc., and this application does not limit this.

[0060] 3) Sensing Signal: This refers to the signal used to sense (or detect) the target (or object, etc.). Sensing signals can also be called detection signals, linear frequency modulated signals, radar signals, radar sensing signals, radar detection signals, environmental sensing signals, etc. Sensing signals can be pulse signals or signals from wireless communication systems. For example, a sensing signal can be an orthogonal frequency division multiplexing (OFDM) signal obtained by modulating a specific sequence on a subcarrier. This specific sequence can be any of the following: Zadoff-Chu sequence (ZC sequence), pseudo-random sequence, predefined sequence, etc. Pseudo-random sequences can include any of the following: longest linear feedback shift register sequence (m-sequence), Gold sequence, etc. Predefined sequences can be random data symbols, such as random data symbols modulated by quadrature phase shift keying (QPSK), quadrature amplitude modulation (QAM), etc.

[0061] 4) Sensing and receiving signals: This refers to the signals received after a sensing signal is sent. Sensing and receiving signals include, for example, echo signals. The echo signal is the signal generated when the sensing signal is reflected by the target. The time delay of the echo signal relative to the sensing signal reflects the distance between the target and the transmitter, and the Doppler shift of the echo signal relative to the sensing signal reflects the target's velocity.

[0062] 5) Communication signals: Signals transmitted between communication devices for communication purposes, such as signals transmitted between network devices and terminal devices. Examples of communication signals include signals carried on the physical downlink shared channel (PDSCH).

[0063] 6) Communication-sensing fusion signal: also written as synesthetic fusion signal, synesthetic signal, synesthetic integrated signal, etc., is a signal used for both communication and sensing. When used for communication, it can be understood that the signal carries the communication data or communication reference signal sequence that needs to be transmitted between communication devices.

[0064] 7) Integrated Communication and Sensing: This is a key technology in next-generation wireless communication networks, aiming to integrate wireless communication and sensing functions into a single system. It utilizes the various propagation characteristics of wireless signals to achieve sensing functions such as target localization, detection, imaging, and identification, thereby acquiring information about the surrounding physical environment, enhancing communication capabilities, and improving user experience. For example, a first device sends a communication-sensing fusion signal, and a second device (or the first device) receives the echo signal reflected from the target in the environment to perform sensing.

[0065] Based on the different senders and receivers of the sensing signals or communication-sensing fusion signals, sensing modes can be divided into two categories: single-site sensing and dual-site sensing. Single-site sensing refers to the same device sending the sensing signals or communication-sensing fusion signals and the same device receiving the sensing signals; dual-site sensing refers to different devices sending the sensing signals or communication-sensing fusion signals and the same device receiving the sensing signals.

[0066] 8) Coherent processing time: This refers to a period of time much longer than the transmission time of a single sensing signal. During the coherent processing time, the transmitting end repeatedly transmits sensing signals multiple times in the same or multiple beam directions. The receiving end receives the corresponding sensing signals and coherently accumulates the sensing signals received from the same beam within this time period to achieve sensing ranging and velocity measurement. Coherent accumulation is generally achieved by performing matched filtering and Fourier transform on all sensing signals received within this time period.

[0067] 9) Downlink (DL): The channel through which data is transmitted from the network device to the terminal device.

[0068] 10) Uplink (UL): The channel through which data is transmitted from the terminal device to the network device.

[0069] 11) Distance resolution: When two targets are located at the same angle and speed relative to a network device, but at different distances relative to the network device, the minimum distance difference that the network device can perceive and distinguish between them is called distance resolution.

[0070] 12) Velocity resolution: When two targets are located at the same angle and distance relative to a network device, but have different velocities relative to the network device, the minimum velocity difference that the network device can perceive and distinguish between them is called velocity resolution.

[0071] 13) Angular resolution: When two targets are at the same distance and speed relative to a network device, but at different angles relative to the network device, the smallest angle difference that the network device can perceive and distinguish between them is called angular resolution.

[0072] 14) Maximum unambiguous speed: The maximum speed of a target that the sensing system can detect.

[0073] 15) Constant False Alarm Rate (CFAR): This is an important method in radar signal processing used to detect target signals in the presence of noise and interference. CFAR achieves a constant false alarm rate by dynamically adjusting the detection threshold, enabling the radar to maintain relatively stable detection performance under different noise levels.

[0074] 16) False alarm rate: The probability that a perception system will falsely detect a target when there is no real target.

[0075] 17) Sensing Function (SF): This is a new network element added to the traditional network architecture of the integrated sensing network. In order to realize sensing capabilities, it is responsible for the control and management of sensing functions, the aggregation and reporting of sensing data.

[0076] In existing wireless sensing systems, after the sensing device receives the sensing signal, the target detection module detects whether a target exists within the coverage area of ​​the sensed region. The target detection module achieves a constant false alarm rate by dynamically adjusting the detection threshold, enabling the sensing system to maintain relatively stable detection performance under different noise levels.

[0077] The basic principle of the target detection module is to estimate the power levels of surrounding noise and interference when detecting a target, and adjust the threshold in real time based on the estimation results to keep the false alarm rate constant. This enhances the target detection effect in complex and changing environments. Specifically, the target detection module first estimates the background noise or clutter level of the detection unit based on the noise statistical characteristics of the received signal. Then, it calculates the difference between the power of the detection unit and the calculated noise power. If the power of the detected unit is greater than the noise power and the difference is greater than the threshold value, the detected unit is a target; otherwise, it is considered noise or clutter.

[0078] However, in real-world sensing scenarios, the presence of strong reflectors or insufficient transmit / receive isolation within the sensing area can lead to excessively high received signal power due to the large radar cross section (RCS) of strong reflectors. This can cause partial or complete saturation of the analog-to-digital converter (ADC), resulting in the receiver link operating in a non-linear range. Consequently, the received signal becomes distorted, indicating anomalies. This can lead to abnormal noise power calculations by the target detection module or obscuring valuable information from the received signal, resulting in a decreased target detection rate and an increased false alarm rate. Similarly, interference in the sensing equipment can introduce interfering signals into the received signal, causing anomalies that can also lead to abnormal noise power calculations by the target detection module or obscuring valuable information from the received signal, further reducing the target detection rate and increasing the false alarm rate.

[0079] Please see Figure 3 This is a schematic diagram of a sensing and receiving signal under interference and a normal sensing and receiving signal provided in an embodiment of this application. Figure 3 The left half of the image shows the sensed and received signal under interference, with a point cloud showing the direction of the interfering wave. Figure 3 The right half of the image represents the normal sensing and receiving signal, and contains a valid target point cloud.

[0080] To this end, embodiments of this application provide a communication method, apparatus, program product, and storage medium that promptly sends abnormal information indicating an anomaly in the received sensing signal along with the sensing result. This allows for the timely receipt of an anomaly response strategy associated with the anomaly information, enabling timely processing based on the anomaly response strategy, such as distrusting the sensing result or adjusting the sensing signal to reacquire the sensing result, thereby reducing the false alarm rate in cases of abnormal received sensing signals.

[0081] Please see Figure 4 This is a schematic diagram of an integrated communication and sensing scenario provided in an embodiment of this application. The communication method provided in this embodiment can be applied to an integrated communication and sensing scenario, where network devices and terminal devices in the communication network can communicate while also sensing objects that do not have communication capabilities. Please refer to... Figure 5 This is a schematic diagram of a sensing mode provided in an embodiment of this application. Figure 4From the perspective of sensing modes, the integrated communication sensing scenario can include six sub-scenarios: base station self-transmission and self-reception, UE self-transmission and self-reception, base station A transmission and base station B reception, UE A transmission and UE B reception, base station transmission and UE reception, and UE transmission and base station reception. Among them, base station self-transmission and self-reception and UE self-transmission and self-reception are single-site sensing modes, while base station A transmission and base station B reception, UE A transmission and UE B reception, base station transmission and UE reception, and UE transmission and base station reception are dual-site sensing modes.

[0082] It should be noted that in the single-site sensing mode where the base station transmits and receives signals simultaneously, the base station will receive its own sensing signals while transmitting sensing signals or sensing fusion signals, thus sensing targets in the environment. This requires the base station to have a certain degree of full-duplex capability, meaning that the base station can transmit and receive signals simultaneously on the same frequency.

[0083] For details, please refer to Figure 6 , Figure 6 A flowchart illustrating a communication method provided for the implementation of this application. Figure 6 Taking a base station self-transmitting and self-receiving scenario as an example, this communication method can be executed by a communication system, which includes a base station and sensing network elements. The communication method provided in this application embodiment may include the following steps:

[0084] S601, The base station sends the first sensing result.

[0085] The first sensing result carries abnormal information, which is used to indicate that there is an abnormality in the first sensing received signal corresponding to the first sensing result.

[0086] In this embodiment of the application, the base station can send a first sensing signal to the sensing area to receive a corresponding first sensing reception signal, and obtain a first sensing result by analyzing the first sensing reception signal. The first sensing result may include information such as the target's position, velocity, and angle.

[0087] S602, The sensing network element receives the first sensing result.

[0088] In this embodiment of the application, after the sensing network element receives the first sensing result, it can determine the corresponding abnormal response strategy based on the abnormal information carried in the first sensing result. In this way, the abnormal response strategy will be associated with the abnormal information, and the abnormal response strategy can be used to specifically deal with the situation where there is an abnormality in the first sensing received signal.

[0089] S603, Strategy for handling abnormal transmissions by sensing network elements.

[0090] In this embodiment of the application, after the sensing network element determines the anomaly response strategy, it can send the anomaly response strategy to the base station. The anomaly response strategy may include, but is not limited to: distrusting the first sensing result, or adjusting the first sensing signal corresponding to the first sensing result to reacquire the sensing result, etc.

[0091] S604, Base Station Reception Anomaly Handling Strategy.

[0092] In the implementation of this application, after the base station receives the anomaly response strategy, it can perform corresponding processing based on the anomaly response strategy, such as distrusting the sensing results or adjusting the sensing signal to reacquire the sensing results, etc.

[0093] It is understood that the embodiments of this application can also be applied to any of the following scenarios: UE self-transmitting and self-receiving, base station A transmitting and base station B receiving, UE A transmitting and UE B receiving, base station transmitting and UE receiving, and UE transmitting and base station receiving. Correspondingly, the UE can also send the first sensing result.

[0094] As can be seen, in this embodiment, the abnormal information indicating that the received sensing signal is abnormal will be sent to the sensing network element along with the sensing result in a timely manner. In this way, the sensing network element can promptly determine the abnormal response strategy associated with the abnormal information and promptly send the abnormal response strategy to the base station. The base station can promptly receive the abnormal response strategy associated with the abnormal information and thus perform corresponding processing in a timely manner based on the abnormal response strategy, such as distrusting the sensing result or adjusting the sensing signal to reacquire the sensing result, etc., thereby reducing the false alarm rate in the case of abnormal received sensing signal.

[0095] Please see Figure 7 , Figure 7 A flowchart illustrating another communication method provided for the implementation of this application. Figure 7 exist Figure 6 Based on the provided communication methods, a more detailed explanation of the communication methods will be given. Figure 7 Taking a base station self-transmitting and self-receiving scenario as an example, this communication method can be executed by a communication system, which includes a base station and sensing network elements. The communication method provided in this application embodiment may include the following steps:

[0096] S701, The base station sends the first sensing signal.

[0097] It should be noted that the first sensing signal in the embodiments of this application can be a sensing signal or a communication sensing fusion signal.

[0098] S702, The base station receives the first sensing reception signal corresponding to the first sensing signal.

[0099] In this application embodiment, the base station can send a first sensing signal to the sensing area to receive a first sensing reception signal generated by the reflection of the first sensing signal by a target in the sensing area.

[0100] S703. The base station analyzes the first sensing received signal, determines that there is an anomaly in the first sensing received signal, and obtains the first sensing result.

[0101] In this application, the base station can analyze the first sensing received signal, calculating indicators such as whether the first sensing received signal has time-domain clipping, the noise intensity of the first sensing received signal, the signal-to-noise ratio and signal-to-interference-plus-noise ratio of the first sensing received signal, and the target shoulder lobe intensity on the range-Doppler (RD) spectrum of the first sensing received signal. By comprehensively determining whether there are anomalies in the first sensing received signal, the base station obtains the first sensing result. Thus, by performing anomaly analysis on the sensing received signal, abnormal information can be reported promptly when anomalies are detected.

[0102] S704, The base station sends the first sensing result.

[0103] The first perception result in this embodiment carries abnormal information. It should be noted that S704 in this embodiment is similar to S601 in the above embodiment, and the same parts will not be described again here.

[0104] In one possible implementation, the abnormal information in this application may include an abnormality indicator code, which is used to indicate whether there is an abnormality in the first sensing and receiving signal. Please refer to Table 1 below, which is a schematic table of abnormality indicator codes. When there is an abnormality in the sensing and receiving signal, the abnormality indicator code is "1", and when there is no abnormality in the sensing and receiving signal, the abnormality indicator code is "0".

[0105] Table 1. Anomaly Indicator Codes

[0106] Error indicator code Meaning of exception indicator codes 0 The received signal was normal. 1 An anomaly was detected in the received signal.

[0107] In this embodiment, if the base station determines that the first sensed received signal is abnormal, it further determines the type of abnormality and the probability of its anomalousness. The probability of its anomalousness indicates the probability of its anomalous type, and its value can range from 0% to 100%. For example, if the sensed received signal exhibits time-domain clipping, it is determined that insufficient transmit / receive isolation leads to signal saturation. The probability of this type of anomalousness is then determined based on the probability of signal clipping. Alternatively, if the noise floor or signal-to-interference-plus-noise ratio (SNR) of the sensed received signal deteriorates significantly in a certain beam or direction, it may indicate co-channel interference in that direction. The probability of this type of anomalousness is determined based on the deterioration of the SNR or SNR. Or, if the shoulder lobe intensity of the main target is very strong in the RD spectrum of the sensed received signal, it may indicate close-range strong target interference. The probability of this type of anomalousness is obtained based on the shoulder lobe intensity. It is understood that the above are merely illustrative examples and should not be construed as limiting the embodiments of this application.

[0108] In one possible implementation, the anomaly information in this application embodiment may include the anomaly type of the first sensed received signal. This means that the specific anomaly type of the sensed received signal is sent along with the sensing result, thereby enabling the reception of anomaly response strategies associated with the specific anomaly type. In other words, a more targeted anomaly response strategy is received, which can further reduce the false alarm rate in cases of anomalies in the sensed received signal.

[0109] In one possible implementation, the anomaly information includes an anomaly type code, which indicates the type of anomaly in the first sensed received signal. Using an anomaly type code to indicate the type of anomaly in the sensed received signal reduces the amount of information carried, enabling timely reporting of sensing results while minimizing communication resources.

[0110] In one possible implementation, the anomaly information also includes an anomaly confidence probability, which indicates the confidence probability of an anomaly type. Combining the anomaly confidence probability and the anomaly type in this way allows for a more targeted anomaly response strategy, which can further reduce the false alarm rate in cases of anomalous received signals.

[0111] Please refer to Table 2 below. Table 2 is a schematic table of anomaly types and their reliability probabilities. Anomaly type code "0" indicates insufficient transmit / receive isolation leading to saturation of the received sensing signal; anomaly type code "1" indicates a near-range stationary strong target causing saturation of the received sensing signal; anomaly type code "2" indicates a near-range moving target causing anomalies in the received sensing signal; and anomaly type code "3" indicates the presence of co-channel interference causing anomalies in the received sensing signal. A, B, C, and D are greater than or equal to 0 and less than or equal to 100.

[0112] Table 2. Anomaly Types and Their Confidence Probability

[0113] Exception type code Exception types Anomaly credibility probability 0 Insufficient transmit / receive isolation leads to saturation of the received sensor signal. A％ 1 Close-range stationary strong targets cause sensor signal saturation. B％ 2 Close-range, highly moving targets cause abnormal sensing and receiving signals C％ 3 Co-channel interference caused abnormal sensor reception signals. D％

[0114] It is understood that if it is determined that there is an anomaly in the first sensing received signal in the implementation of this application, the first sensing result may carry an anomaly indicator code, anomaly type and anomaly confidence probability, or carry an anomaly indicator code, anomaly type code and anomaly confidence probability; if it is determined that there is no anomaly in the first sensing received signal, there is no need to carry anomaly information in the first sensing result.

[0115] S705, the sensing network element receives the first sensing result.

[0116] It should be noted that S705 in this embodiment is similar to S602 in the above embodiment, and the same parts will not be described again here.

[0117] S706. Based on abnormal information, the sensing network element determines the abnormal response strategy.

[0118] In one possible implementation, the anomaly response strategy includes a first indication message indicating whether to disable the sensing function. This allows for timely disabling of the sensing function when the sensing results are not trusted due to abnormal receiving signals, reducing the false alarm rate and sensing overhead.

[0119] The first indication information in this embodiment may include a sensing function indication code. Please refer to Table 3 below. Table 3 is a schematic table of sensing function indication codes. When the sensing function indication code is "0", it indicates that the sensing function is turned off. When the sensing function indication code is "1", it indicates that the sensing function is not turned off.

[0120] Table 3. Illustrated Table of Sensory Function Indicator Codes

[0121] Sensing function indicator code Meaning of Sensing Function Indicator Code 0 Turn off sensing function 1 Do not turn off the sensing function

[0122] In one possible implementation, the first indication information in this embodiment can specifically be used to indicate whether to disable the sensing function of the sensed area or beam direction corresponding to the first sensing received signal, that is, to indicate whether the base station continues to report the sensing results of the sensed area or beam direction corresponding to the first sensing received signal. Specifically, if the indication is to disable the sensing function of the sensed area corresponding to the first sensing received signal, the base station will no longer send sensing signals to that sensed area and will not continue to report the sensing results corresponding to that sensed area to the sensing network element; if the indication is not to disable the sensing function of the sensed area corresponding to the first sensing received signal, the base station will continue to send sensing signals to that sensed area and will continue to report the sensing results corresponding to that sensed area to the sensing network element. Similarly, if the indication is to disable the sensing function of the beam direction corresponding to the first sensing received signal, the base station will no longer send sensing signals to that beam direction and will not continue to report the sensing results corresponding to that beam direction to the sensing network element; if the indication is not to disable the sensing function of the beam direction corresponding to the first sensing received signal, the base station will continue to send sensing signals to that beam direction and will continue to report the sensing results corresponding to that beam direction to the sensing network element.

[0123] For example, if the sensing network element detects prolonged interference at the base station, it can instruct the sensing function to be disabled. Alternatively, if the sensing network element receives a normal sensing result reported by another base station, and this sensing result and the first sensing result both pertain to the same sensing area, it can instruct the sensing function to be disabled, and so on. It is understood that the above is merely illustrative and should not be construed as limiting the embodiments of this application.

[0124] In one possible implementation, the anomaly response strategy includes a second indication message, which instructs adjustment of the first sensing signal corresponding to the first sensing result. This allows for timely adjustment of the sensing signal in the event of an anomaly in the received sensing signal, enabling the subsequent acquisition of a more accurate sensing result, thereby reducing the impact of the anomaly and lowering the false alarm rate.

[0125] In one possible implementation, the second indication information is specifically used to indicate the adjustment method of the first sensing signal corresponding to the first sensing result. The adjustment method includes, but is not limited to, switching the waveform of the first sensing signal, adjusting the transmission power of the first sensing signal, adjusting the frequency of the first sensing signal, adjusting the target detection threshold of the first sensing signal, adjusting the starting position of the frequency domain resource block of the first sensing signal, adjusting the length of the frequency domain resource block, adjusting the time domain time slot of the first sensing signal, or adjusting the time domain symbol of the first sensing signal, etc.

[0126] In one possible implementation, the second indication information is specifically used to indicate at least one of the following: switching the waveform of the first sensing signal, adjusting the transmission power of the first sensing signal, adjusting the frequency of the first sensing signal, adjusting the target detection threshold of the first sensing signal, adjusting the start position of the frequency domain resource block of the first sensing signal, adjusting the length of the frequency domain resource block, adjusting the time domain time slot of the first sensing signal, or adjusting the time domain symbol of the first sensing signal, etc. This allows for the acquisition of specific signal adjustment methods, enabling targeted adjustments to the first sensing information, thereby subsequently obtaining a relatively normal sensing reception signal and reducing the false alarm rate.

[0127] In one possible implementation, the second indication information in this application embodiment may include a signal adjustment indicator code and adjustment information. The signal adjustment indicator code and adjustment information are used to indicate the adjustment method of the first sensing signal corresponding to the first sensing result. Please refer to Table 4 below. Table 4 is a schematic table of signal adjustment indicator codes and adjustment information. A signal adjustment indicator code of "0" indicates switching the waveform of the first sensing signal; a signal adjustment indicator code of "1" indicates adjusting the transmission power of the first sensing signal; a signal adjustment indicator code of "2" indicates adjusting the frequency point of the first sensing signal; a signal adjustment indicator code of "3" indicates adjusting the target detection threshold of the first sensing signal; and a signal adjustment indicator code of "4" indicates adjusting the frequency domain resources and / or time domain resources of the first sensing signal. The specific values ​​of X, Fc, and Y can be set according to the actual situation.

[0128] Table 4. Signal Adjustment Indicator Codes and Adjustment Information

[0129]

[0130] It is understood that the signal adjustment indicator codes and adjustment information in this application embodiment include, but are not limited to, the types provided in Table 4 above. In this application embodiment, an anomaly response strategy can be determined based on the anomaly type and the anomaly confidence probability.

[0131] For example, if a sensing network element receives an anomaly type code of "0" from a base station, and the anomaly confidence probability is 90%, then the anomaly response strategy sent by the sensing network element to the base station may include a signal adjustment indication code of "0" and an adjustment information of "1," instructing the base station to switch the waveform of the first sensing signal to a pulse wave mode. This waveform selection can avoid the problem of insufficient transmit / receive isolation leading to sensing signal saturation. It is understood that the above is merely an illustrative example and should not be construed as limiting the embodiments of this application.

[0132] For example, if a sensing network element receives an anomaly type code of "1" from a base station, and the anomaly confidence probability is 95%, then the anomaly response strategy sent by the sensing network element to the base station may include a signal adjustment indication code of "1" and adjustment information of "X dBm," instructing the base station to adjust the transmission power of the first sensing signal to X dBm, which is less than the base station's original transmission power. By reducing the transmission power, the saturation anomaly of the received sensing signal is eliminated. It is understood that the above is merely an illustrative example and should not be construed as a limitation on the embodiments of this application.

[0133] For example, if a sensing network element receives an anomaly type code "2" from a base station, with an anomaly confidence probability of 90%, then the anomaly response strategy sent by the sensing network element to the base station may include a signal adjustment indication code "3" and adjustment information "Y dB". This instructs the base station to adjust the target detection threshold of the first sensing signal to Y dB. Y dB is higher than the base station's original target detection threshold. By increasing the target detection threshold, the problem of abnormal sensing reception signals caused by close-range, strongly moving targets is solved. It is understood that the above is merely an illustrative example and should not be construed as a limitation on the embodiments of this application.

[0134] For example, if a sensing network element receives an anomaly type code "3" from a base station, with an anomaly confidence probability of 90%, then the anomaly response strategy sent by the sensing network element to the base station may include a signal adjustment indicator code of "2" and adjustment information of "Fc Hz," indicating a switch to the base station's overall frequency point at Fc Hz to avoid interference in the frequency domain. Another more refined indication is that the anomaly response strategy sent by the sensing network element to the base station may include an adjustment indicator code of "4" and adjustment information of "RB start," "RB length," "Slot Id," and "Symbold Id." This simultaneously indicates the transmission position of the sensing signal in both the time and frequency domains, avoiding interference at the precise transmission position of the sensing symbol. This method is suitable for signals with interference that are not at full bandwidth or full duty cycle. It is understood that the above is merely an illustrative description and should not be construed as a limitation on the embodiments of this application.

[0135] S707, Strategy for handling abnormal transmissions by sensing network elements.

[0136] It is understood that S707 in this embodiment is the same as S603 in the above embodiment, so it will not be described again.

[0137] S708, Base Station Reception Anomaly Handling Strategy.

[0138] It is understood that S708 in this embodiment is the same as S604 in the above embodiment, so it will not be described again.

[0139] It should be noted that if the first instruction message indicates that the sensing function is turned off, then S709 to S714 do not need to be executed.

[0140] S709. The base station adjusts the first sensing signal based on the anomaly response strategy to obtain the second sensing signal.

[0141] In this embodiment, the waveform of the first sensing signal can be switched, and / or the transmission power of the first sensing signal can be adjusted, and / or the frequency point of the first sensing signal can be adjusted, and / or the target detection threshold of the first sensing signal can be adjusted, and / or the starting position of the frequency domain resource block of the first sensing signal can be adjusted, and / or the length of the frequency domain resource block can be adjusted, and / or the time domain time slot of the first sensing signal can be adjusted, and / or the time domain symbol of the first sensing signal can be adjusted, etc., to obtain the second sensing signal.

[0142] S710, the base station sends a second sensing signal.

[0143] It should be noted that the second sensing signal in the embodiments of this application can be a sensing signal or a communication sensing fusion signal.

[0144] S711, The base station receives the second sensing reception signal corresponding to the second sensing signal.

[0145] In this application embodiment, the base station can send a second sensing signal to the sensing area to receive a first sensing reception signal generated by the reflection of the second sensing signal by a target in the sensing area.

[0146] S712, The base station analyzes the second sensing received signal to obtain the second sensing result.

[0147] In this embodiment, the second sensing result is the sensing result obtained after adjustment based on the anomaly response strategy. This results in a more accurate second sensing result and reduces the false alarm rate when the received signal is abnormal.

[0148] S713, the base station sends the second sensing result.

[0149] S714, the sensing element receives the second sensing result.

[0150] It is understood that the embodiments of this application can also be applied to any of the following scenarios: UE self-transmitting and self-receiving, base station A transmitting and base station B receiving, UE A transmitting and UE B receiving, base station transmitting and UE receiving, and UE transmitting and base station receiving. Correspondingly, the UE can also send the first sensing signal and the second sensing signal, and the UE can receive the first sensing reception signal and the second sensing reception signal, etc.

[0151] As can be seen, in this embodiment, the first sensing received signal is analyzed to determine whether there are abnormalities such as signal saturation, strong reflection from close-range targets, or co-channel interference. If the base station determines that there may be abnormalities in the sensing received signal, the base station sends the first sensing result to the sensing network element carrying abnormal information, including the abnormality type and probability. Based on the abnormal information, the sensing network element instructs the base station to perform area shielding or signal adjustment. In this way, the abnormality of the sensing received signal is reported to the sensing network element in a timely manner along with the sensing result. The sensing network element makes a comprehensive decision based on the abnormal information reported by the sensing base station, enabling the base station to perform abnormal shielding or signal adjustment in a timely manner, thereby reducing the impact of abnormal sensing received signal and reducing the false alarm rate under abnormal sensing received signal conditions. That is, the purpose of reducing the false alarm rate is achieved through a series of interactions between the base station and the sensing network element regarding abnormal sensing received signal conditions.

[0152] It should be noted that, for the sake of simplicity, the foregoing method embodiments are all described as a series of actions. However, those skilled in the art should understand that this application is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to this application.
