Description

Technical Field

[0001] This application belongs to the field of communication technologies, and particularly relates to a sensing processing method, apparatus, device, and readable storage medium. Background Art

[0002] The performance of bistatic sensing depends on whether the sensing signal receiving device can receive the echo signal reflected by the sensing target from the signal sent by the sensing signal sending device with sufficient strength. For the sensing signal receiving device or the sensing signal sending device at some locations, the communication coverage is poor or even there is no communication ability (for example, the communication signal cannot meet the receiving sensitivity requirement); however, these locations have the ability of wireless sensing because the sensing signal can obtain the gain of sensing coherent processing, and in some cases, its sensitivity requirement is lower than that of communication, or these locations are exactly the directions where the radar cross section (RCS) of the sensing target is relatively large. The main purpose of the sensing signal receiving device or the sensing signal sending device (i.e., the sensing auxiliary device) deployed at these locations is to support the sensing service and fill the sensing coverage holes. How the sensing auxiliary device reports its sensing ability is an urgent problem to be solved. Summary of the Invention

[0036] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0037] The terms "first", "second", etc. in the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such terms can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first" and "second" are usually of the same type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "or" in the present application means at least one of the connected objects. For example, "A or B" covers three scenarios, namely, Scenario 1: including A and not including B; Scenario 2: including B and not including A; Scenario 3: including both A and B. The character " / " generally indicates an "or" relationship between the associated objects before and after.

[0038] It should be noted that the technology described in the embodiments of this application is not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency Division Multiple Access (SC-FDMA), or other systems. The terms "system" and "network" in this application are often used interchangeably, and the described technology can be used in the above-mentioned systems and radio technologies, as well as in other systems and radio technologies. The following description describes the New Radio (NR) system for example purposes, and the NR term is used in most of the following descriptions, but these technologies can also be applied to systems other than NR system applications, such as the 6th Generation (6 th Generation, 6G) communication system.

[0039] To facilitate the understanding of the embodiments of this application, the following technical points are introduced first:

[0040] I. Regarding communication and sensing integration.

[0041] Future mobile communication systems, such as Beyond 5th Generation (B5G) mobile communication systems or 6th Generation (6G) mobile communication systems, will not only have communication capabilities but also sensing capabilities in the future. The sensing capability means that one or more devices with sensing capabilities can sense information such as the orientation, distance, and speed of a target object through the transmission and reception of wireless signals, or detect, track, identify, image, etc. a target object, event, or environment. In the future, with the deployment of small base stations with high-frequency band and large bandwidth capabilities such as millimeter waves and terahertz waves in the 6G network, the sensing resolution will be significantly improved compared to centimeter waves, enabling the 6G network to provide more refined sensing services. Typical sensing functions and application scenarios are shown in Table 1.

[0042]

[0043] Table 1: Typical sensing functions and application scenarios.

[0044] Communication perception integration (abbreviated as communication-sensing integration) means that in the same system, through spectrum sharing and hardware sharing, the integrated design of communication and perception functions is realized. While the system is transmitting information, it can sense information such as direction, distance, and speed, detect, track, and identify target devices or events. The communication system and the perception system complement each other, achieving an improvement in overall performance and bringing a better service experience.

[0045] The integration of communication and radar belongs to a typical application of communication perception integration (communication-sensing fusion). In the past, radar systems and communication systems were strictly separated due to different research objects and focuses of attention, and the two systems were studied independently in most scenarios. In fact, both radar and communication systems are typical ways of information transmission, acquisition, processing, and exchange, and there are many similarities in terms of working principles, system architectures, and frequency bands. The design of communication-radar integration has great feasibility, which is mainly reflected in the following aspects: First, both the communication system and the perception system are based on electromagnetic wave theory, and use the emission and reception of electromagnetic waves to complete information acquisition and transmission; Second, both the communication system and the perception system have structures such as antennas, transmitters, receivers, and signal processors, and there is a large overlap in hardware resources; With the development of technology, there is also more and more overlap in their working frequency bands; In addition, there are similarities in key technologies such as signal modulation, reception detection, and waveform design. The integration of communication and radar systems can bring many advantages, such as cost savings, size reduction, power consumption reduction, spectrum efficiency improvement, and mutual interference reduction, thus improving the overall performance of the system.

[0046] According to the different target signal sending nodes and receiving nodes, it is divided into 6 basic sensing methods, as Figure 1 shown, specifically including:

[0047] (1) Base station echo sensing. In this sensing method, base station A sends a target signal and performs sensing measurements by receiving the echo of the target signal.

[0048] (2) Air interface sensing between base stations. Base station B receives the target signal sent by base station A and performs sensing measurements.

[0049] (3) Uplink air interface sensing. Base station A receives the target signal sent by terminal A and performs sensing measurements.

[0050] (4) Downlink air interface sensing. Terminal B receives the target signal sent by base station B and performs sensing measurements.

[0051] (5) Terminal echo sensing. Terminal A sends a first signal and performs sensing measurements by receiving the echo of the target signal.

[0052] (6) Sidelink (SL) sensing between terminals. Terminal B receives the target signal sent by Terminal A and performs sensing measurements.

[0053] It should be noted that Figure 1 each sensing method in takes a target signal sending node and a target signal receiving node as examples. In an actual system, one or more different sensing methods can be selected according to different sensing use cases and sensing requirements, and there can be one or more sending nodes and receiving nodes for each sensing method. Figure 1 The sensing targets in use people and vehicles as examples, and it is assumed that neither people nor vehicles carry or install signal receiving or transmitting devices. The sensing targets in the actual scenario are more diverse.

[0054] The above-mentioned target signal includes at least one of a reference signal, a synchronization signal, a data signal, and a dedicated signal. Sensing services can be supported by receiving or sending the target signal. For example, sensing measurement quantities or sensing results can be obtained by receiving or sending the target signal. The sensing result refers to the result that meets the sensing requirements. For example: the shape of the sensing target, 2D or 3D environment reconstruction, spatial position, orientation, displacement, moving speed, acceleration; speed measurement, distance measurement, angle measurement, or imaging of the target object in radar-based sensing; the presence or absence of people or objects; actions, gestures, breathing frequency, heart rate, sleep quality, etc. of the sensing target such as people.

[0055] The above target signal can be a signal that does not contain transmission information, such as existing LTE or New Radio (NR) synchronization and reference signals, including Synchronization Signal and PBCH block (SSB) signals, Channel State Information-Reference Signal (CSI-RS), Demodulation Reference Signal (DMRS), Sounding Reference Signal (SRS), Positioning Reference Signal (PRS), Phase Tracking Reference Signal (PTRS), etc.; it can also be a single-frequency continuous wave (CW), frequency-modulated continuous wave (FMCW), and ultra-wideband Gaussian pulse commonly used in radar; it can also be a newly designed dedicated signal with good correlation characteristics and low peak-to-average power ratio, or a newly designed integrated communication and sensing signal that not only carries certain information but also has good sensing performance. For example, the new signal is formed by splicing, combining, or superimposing at least one dedicated reference signal and at least one communication signal in the time domain or frequency domain.

[0056] II. Regarding the Low Power Wake-Up Signal (WUS) or Wake-Up Radio (WUR).

[0057] The basic working principle of the LP WUR is that the receiving end includes a first unit and a second unit. The first unit is the main communication unit used to receive and transmit communication data from the sending end. The second unit is the low-power unit used to receive the low-power wake-up signal (LP-WUS) and low-power synchronization signal (Low Power Synchronization Signal, LP-SS) sent by the sending end. The low-power wake-up signal is used to wake up the main communication unit of the receiving end, and the low-power synchronization signal is used to provide time reference information and other information for receiving the low-power wake-up signal. For example, it is used for radio resource management (RRM) measurements of the serving cell and can also provide wake-up link management, such as determining whether to activate or deactivate the LP-WUR based on the measurement results and closing the Measurement Report (MR). As Figure 2As shown, when the first unit is not awakened by the second unit, it remains in the off state and does not send or receive data. When there is downlink data arriving, the second unit detects the wake-up signal sent by the sending end, and if this wake-up signal contains the information of this terminal, the second unit triggers the first unit to switch from the off state to the working state for data reception and transmission. The second unit can be continuously turned on or not continuously turned on. When the second unit is turned on, it can receive low-power wake-up signals and low-power synchronization signals.

[0058] III. Regarding Backscatter Communication (BSC).

[0059] Backscatter communication refers to that backscatter communication devices use radio frequency signals in other devices or the environment for signal modulation to transmit their own information. The types of backscatter communication devices can be:

[0060] - Device A: The backscatter communication device in traditional Radio-Frequency Identification (RFID) is generally a tag, belonging to Passive Internet of Things (Passive-IoT) devices;

[0061] - Device B: Semi-passive Internet of Things (IoT) devices. These devices have a certain amplification ability for downlink reception or uplink reflection;

[0062] - Device C: Devices with the ability to actively send (active devices). Such terminals can send information to the reader without relying on the reflection of the incident signal.

[0063] The energy source of such devices can come from the environment, such as Radio-Frequency (RF) signals, thermal energy, kinetic energy, wind energy, etc., and they can also be called Ambient IoT devices.

[0064] See Figure 3 , for the transmission method based on backscattering, a simple implementation is that when the Tag needs to send '1', the Tag reflects the incident carrier signal, and when the Tag needs to send '0', it does not reflect.

[0065] See Figure 4 , the backscatter communication device controls the reflection coefficient Γ of the circuit by adjusting its internal impedance, thereby changing the amplitude, frequency, phase, etc. of the incident signal to achieve signal modulation. Among them, the reflection coefficient of the signal can be characterized as:

[0066] Γ = (Z_1 - Z_0) / (Z_1 + Z_0) = |Γ|e^(jθ_T)

[0067] Where Z_0 is the antenna characteristic impedance and Z_1 is the load impedance. Assuming the incident signal is S_in(t), then the output signal is S_out(t) = S_in(t)|Γ|e^(jθ_T). Therefore, corresponding amplitude modulation, frequency modulation, or phase modulation can be achieved by reasonably controlling the reflection coefficient.

[0068] IV. Regarding monostatic sensing, bistatic sensing between the base station and the UE.

[0069] The advantage of monostatic sensing (such as the base station transmitting and receiving on its own) is that there is no synchronization problem between the transmitting and receiving nodes. One of the disadvantages is that the sensing node needs to have full-duplex capabilities to avoid the impact of self-interference. Another disadvantage is that the sensing node can only "see" the side of the sensing target facing itself and cannot "see" other sides of the sensing target. Since the radar cross section (RCS) of most sensing targets is different at different angles, the RCS at some angles will be relatively small, affecting the sensing performance at those angles.

[0070] To address the disadvantages of monostatic sensing, multi-point collaborative sensing can be considered. Bistatic sensing is the simplest form of multi-point collaborative sensing, including bistatic sensing between base stations, bistatic sensing between the base station and the UE, etc. In the case of bistatic sensing between base stations, since the positions of the base stations are generally fixed, there may be a situation where the base stations are far from the sensing target, resulting in the problem that the sensing results for some target positions are difficult to meet the sensing requirements.

[0071] Bistatic sensing between the base station and the UE (such as the base station transmitting and the UE receiving) can reuse the existing frame structure and existing signals. By selecting a suitable UE (such as a UE closer to the sensing target) to participate in the sensing process, the sensing coverage performance can be improved. Its disadvantage is that the estimation errors of the UE's position, orientation, and speed, as well as the synchronization error between the base station and the UE, will affect the sensing performance. A corresponding solution is to introduce a special sensing-assisted UE. The sensing-assisted UE can be placed at a position closer to the sensing target as needed and remain relatively stationary. Its position and orientation are known to avoid the impact of the estimation errors of the UE's position, orientation, and speed on the sensing performance. For the differences between the sensing-assisted UE and the ordinary UE, please refer to Table 2.

[0072] Table 2: Differences between the sensing-assisted UE and the ordinary UE.

[0073]

[0074] For example, in some sensing service scenarios such as the scenario of drone delivery, multiple aerial corridors have been opened up in the city and are specifically covered by base stations. However, due to the sensing mode where only the base station sends and receives by itself or the base station sends and other stations receive, the location of the sensing base station is restricted and cannot fully cover multiple aerial corridors to meet their sensing requirements.

[0075] The following will, with reference to the accompanying drawings, through some embodiments and their application scenarios, elaborate in detail on the sensing processing method, device, communication equipment, and readable storage medium provided by the embodiments of the present application.

[0076] See Figure 5 , the embodiments of the present application provide a sensing processing method, and the specific steps include: Step 501.

[0077] Step 501: The first device sends the sensing capabilities of the first device to the second device through the first transceiver unit; wherein, the sensing capabilities include at least one of the following:

[0078] 1) Only support sending the first signal;

[0079] For example, the sensing unit of the first device only supports sending the first signal, that is, the sensing unit only has the ability to send the first signal and does not support measuring the first signal.

[0080] 2) Only support measuring the second signal;

[0081] For example, the sensing unit of the first device only supports measuring the second signal, that is, the sensing unit only has the ability to measure the second signal and does not support sending the second signal.

[0082] 3) Only support sending the third signal and measuring the third signal;

[0083] For example, the sensing unit of the first device only supports sending the third signal and measuring the third signal (for example, the echo of the third signal), that is, the sensing function only has the ability to send the third signal and measure the third signal.

[0084] 4) Only support sending the fourth signal and support measuring the fifth signal. For example, the sensing unit of the first device only supports sending the fourth signal and supports measuring the fifth signal, that is, the sensing function only has the ability to send the fourth signal and measure the fifth signal;

[0085] In the present application, the second device can, according to the sensing capabilities of the first device, instruct the first device to participate in sensing, for example, instruct the first device to send the signals it supports for sensing, or instruct the first device to measure the signals it supports to obtain sensing measurement quantities, etc.

[0086] In this application, the sensing service can be supported by sending a first signal, or receiving a second signal, or sending and receiving a third signal, or sending a fourth signal and receiving a fifth signal. For example, a sensing measurement or a sensing result can be obtained by receiving or sending the first signal. The sensing result refers to a result that meets the sensing requirements, such as: the shape of the sensing target, 2D or 3D environment reconstruction, spatial position, orientation, displacement, moving speed, acceleration; speed measurement, distance measurement, angle measurement or imaging of a target object by radar-like sensing; the presence or absence of a person or an object; actions, gestures, breathing frequency, heart rate, sleep quality, etc. of a sensing target such as a person.

For example, the new signal is formed by splicing, combining, or superimposing at least one dedicated reference signal and at least one communication signal in the time domain or the frequency domain.

[0088] In an implementation manner of this application, the sensing capability further includes at least one of the following:

[0090] For example, the waveform type of the first signal, the third signal, or the fourth signal sent by the sensing unit of the first device;

[0091] 2) The waveform type of the second signal, the third signal, or the fifth signal;

[0093] Optionally, the waveform type includes at least one of the following: Orthogonal Frequency-Division Multiplexing (OFDM) waveform, pulse waveform, Frequency Modulated Continuous Wave (FMCW), other waveforms.

[0094] For example, the first device only supports sending a first signal with a pulse waveform as the waveform type and does not support measuring the first signal. Alternatively, the first device only supports measuring a second signal with a frequency modulated continuous wave as the waveform type and does not support sending the second signal.

[0095] Optionally, the first device may be a sensing auxiliary device. For example, the first device may include at least one of a terminal and a network-side device. The second device may include at least one of a terminal and a network-side device.

It may be located on the radio access network (RAN) side or the core network side, that is, it may be a network node in the core network or RAN responsible for at least one of functions such as sensing request processing, sensing resource scheduling, sensing information interaction, and sensing data processing. For example, it may be upgraded based on the access and mobility management function (AMF) or location management function (LMF) in a 5G network, or it may be other network nodes or newly defined network nodes.
