A sensing method and corresponding device

[0001] This application claims priority to Chinese Patent Application No. 202411748430.1, filed with the State Intellectual Property Office of China on November 28, 2024, entitled "A Sensing Method and Corresponding Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, specifically to a sensing method and corresponding device. Background Technology

[0003] In the field of communications, the allocation of time and frequency resources is one of the key technologies for managing and allocating wireless resources to optimize network performance. By combining frequency division multiplexing (FDM) and time division multiplexing (TDM), networks can utilize spectrum resources more efficiently.

[0004] In cellular networks, time-frequency resources are dynamically allocated by access network equipment (such as base stations) based on user demand, channel conditions, and quality of service (QoS) requirements. Access network equipment can configure different time-frequency resource particles with different resource patterns for different terminal devices. This allows the terminal devices to transmit signals using the time-frequency resource particles at the corresponding locations indicated by the resource pattern, enabling flexible scheduling of time-frequency resources to adapt to user needs and channel conditions.

[0005] Currently, resource patterns can be used in the communications field to meet user needs. In the sensing field, however, how to utilize resource patterns to meet sensing performance requirements has become an urgent problem to be solved. Summary of the Invention

[0006] This application provides a sensing method for achieving good sensing performance with fewer resources. This application also provides corresponding apparatus, computer-readable storage media, and computer program products.

[0007] This application provides a sensing method, which can be applied to a first communication device. The first communication device can refer to the device itself, a component within the device (e.g., a processor, circuit, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the first communication device. The circuit or chip responsible for communication functions can be a modem chip (also known as a baseband chip), a system-on-a-chip (SoC) chip containing a modem core, or a system-in-package (SIP) chip. The device can be a network device or a terminal device, and the network device can include access network equipment or core network equipment. The method includes: acquiring information about at least one sensing direction for sensing, and information about a first sensing performance requirement corresponding to each sensing direction; sending resource configuration indication information to a second communication device; wherein the resource configuration indication information is used to indicate a first resource pattern, the first resource pattern is used by the second communication device for sensing, and the first resource pattern satisfies the first sensing performance requirement corresponding to each sensing direction.

[0008] In this application, the first communication device can be a central node, a sensing function (SF) network element, a sensing management function (SMF) network element, a transmitting node, or a receiving node, etc. The central node can be a node that configures sensing parameters for the transmitting end or the receiving end of the sensing signal, and / or a node that summarizes the sensing results. The central node can be a network device or a chip within a network device; of course, the central node can also be other types of devices. The SF network element or SMF network element can be a node used for sensing function management, and its function and form can be the same as or similar to the central node. A transmitting node refers to a node used to transmit sensing signals, also called a transmitter, and a receiving node refers to a node used to receive the echo signal of the sensing signal, also called a receiver. The transmitting node and the receiving node can be access network equipment or terminal equipment.

[0009] In this application, the second communication device may be a device corresponding to a transmitting node, a device corresponding to a receiving node, or a device corresponding to a sensing node; wherein, a sensing node refers to a node that integrates a transmitting end for sensing signals and a receiving end for echo signals.

[0010] In this application, the transmitting node can be an access network device or a chip in the access network device, and the transmitting node can also be a terminal device or a chip in the terminal device; the receiving node can be an access network device or a chip in the access network device, and the receiving node can also be a terminal device or a chip in the terminal device; the sensing node can be an access network device or a chip in the access network device, and the sensing node can also be a terminal device or a chip in the terminal device.

[0011] In this application, the first communication device may receive information about at least one sensing direction and information about the first sensing performance requirements corresponding to each sensing direction from the core network or the second communication device. Alternatively, the first communication device may determine information about at least one sensing direction and information about the first sensing performance requirements corresponding to each sensing direction on its own.

[0012] In this application, the information of the sensing direction is used to indicate the sensing direction. The sensing direction can be a sensing direction in the resource domain or a direction in the transform domain, where the transform domain refers to the domain after the Fourier transform of the resource domain.

[0013] In this application, the resource domain may include the time-frequency domain, the antenna domain, or the spatial-frequency domain. The time-frequency domain refers to the resource domain formed by time-domain resources and frequency-domain resources. The antenna domain refers to the resource domain formed by the spatial resources of the two-dimensional antenna array, such as the spatial resources provided by the two-dimensional antenna array in the azimuth direction and the spatial resources provided in the elevation direction. The spatial-frequency domain refers to the resource domain formed by the spatial resources and frequency resources provided by the antenna array. For example, the resource domain formed by the spatial resources and frequency resources provided by the antenna array in the observation angle direction, where the observation angle refers to the angle of the observed target point / target area center point relative to the transmitting node and / or receiving node.

[0014] In this application, the transform domain of the time-frequency domain can be the time-delay-Doppler domain. The image in the time-delay-Doppler domain characterizes the distribution of signals transmitted / received through time-domain and frequency-domain resources in the time-delay-Doppler direction. The performance of signals transmitted / received through time-domain and frequency-domain resources can be measured using this image. In this application, the transmitted signal refers to the sensed signal, and the received signal refers to the echo signal corresponding to the sensed signal.

[0015] In this application, the transformation domain of the rooftop domain can be the angle domain, such as the azimuth-elevation domain. The image in the azimuth-elevation domain characterizes the distribution of the signal transmitted / received by the two-dimensional antenna array in the azimuth-elevation direction. The performance of the signal transmitted / received by the two-dimensional antenna array can be measured through the image in the azimuth-elevation domain.

[0016] In this application, the transform domain of the spatial-frequency domain can be the image domain; the image in the image domain characterizes the performance of the signal transmitted / received through the spatial and frequency domain resources in the direction of the observation angle, and the image can measure the performance of the signal at different components of the observation angle.

[0017] In this application, the sensing direction can be at least one of the following: a time-frequency domain direction, a two-dimensional antenna array direction, or an antenna array-frequency domain direction in the resource domain; or, the sensing direction can be at least one of the following: a time-delay-Doppler direction, an azimuth-elevation direction, or a frequency component direction in the transform domain. Taking the time-delay-Doppler direction as an example, the sensing direction can include one or more time-delay-Doppler directions, such as: a zero-delay-Doppler direction, a zero-Doppler-time-delay and a 45° time-delay-Doppler intersection direction, etc. Of course, the time-delay-Doppler directions listed here are just examples; in reality, there can be many more time-delay-Doppler directions, and other types of sensing directions can also be one or more.

[0018] In this application, the information regarding the first sensing performance requirement is used to indicate the first sensing performance requirement. This requirement information may include one or more parameters indicating sensing performance, such as: the main lobe width of the ambiguity function, the side lobe height of the ambiguity function (e.g., peak-to-sidelobe ratio (PSLR) or integrated sidelobe ratio (ISLR)), or at least one of the unambiguity of the ambiguity function. The main lobe width of the ambiguity function refers to the resolution performance. Resolution refers to the minimum interval in the imaging result that can distinguish adjacent targets, such as distance interval or angular interval, which determines the fineness of the imaging and the target discrimination ability. The side lobe height of the ambiguity function refers to the sensing performance for weak targets; if the side lobe height is high, weak targets will be submerged in the side lobes of strong targets. The unambiguity of the ambiguity function refers to the range within which the imaging result will not produce confusion or repetition when measuring distance, angle, and velocity; it is used to ensure the accuracy and reliability of measurements and avoid confusion and misunderstanding of target information. Of course, the information required for first-sensing performance may also include signal-to-interference-plus-noise ratio (SINR), gain, etc., but this application does not limit this.

[0019] In this application, the fuzzy function can also be called the point spread function (PSF). The fuzzy function characterizes the performance distribution of the signal (the autocorrelation function of the signal) in the exchange domain corresponding to the resource domain. For example, it characterizes the distribution of the signal in the time-delay-Doppler domain. The performance of the signal transmitted / received in the time-frequency domain can be measured by the fuzzy function in the time-delay-Doppler domain.

[0020] In this application, the information of the first sensing performance requirement corresponding to each sensing direction refers to one or more parameters for indicating the first sensing performance requirement corresponding to each sensing direction, such as one or more parameters for indicating sensing performance corresponding to the zero-latency-Doppler direction, one or more parameters for indicating sensing performance corresponding to the zero-Doppler-latency direction, and one or more parameters for indicating sensing performance corresponding to the latency-Doppler 45° cross direction.

[0021] In this application, the first resource pattern refers to the distribution of resource particles within the resource domain described above. Here, a resource particle refers to a unit of resource division within the corresponding resource domain. For example:

[0022] In the time-frequency domain, the first resource pattern refers to the distribution of resource particles formed by time-domain resources and frequency-domain resources. Resource particles in the time-frequency domain can be resource elements (REs), or resource blocks (RBs) or other time-frequency resource partitioning units. This application does not limit this.

[0023] In the sky domain, the first resource pattern refers to the distribution of resource particles formed by a two-dimensional antenna array. The resource particles on the two-dimensional antenna array can be antenna elements or antenna ports.

[0024] In the spatial-frequency domain, the first resource pattern refers to the distribution of spatial and frequency domain resource blocks at different components of the observation angle. The resource particle represents the unit of spatial and frequency domain resources at different components of the observation angle. For example: f x =fsinθ,f y = fcosθ, where θ is the observation angle, i.e., the angle between the observed target point / target region center point and the transmitting node and / or receiving node, and f represents the frequency of the frequency domain resource. x f represents the frequency domain resource in the x-axis direction. y This represents the component of the frequency domain resource along the y-axis.

[0025] In this application, the first resource pattern satisfying the first sensing performance requirement for each sensing direction means that the performance of the signals transmitted / received on the resource particles indicated by the first resource pattern can reach or exceed the first sensing performance requirement for each sensing direction. For example, the actual resolution in each sensing direction is better than the required resolution indicated by the first sensing performance requirement, and / or the actual ambiguity is better than the required ambiguity indicated by the first sensing performance requirement. For example, in the information of the first sensing performance requirement: the main lobe width of the ambiguity function corresponding to the zero-delay-Doppler direction is A1, the side lobe height of the ambiguity function is B1, and the ambiguity is C1; the main lobe width of the ambiguity function corresponding to the zero-Doppler-delay direction is A2, the side lobe height of the ambiguity function is B2, and the ambiguity is C2; the main lobe width of the ambiguity function corresponding to the delay-Doppler 45° intersection direction is A3, the side lobe height of the ambiguity function is B3, and the ambiguity is C3. In this case, the first resource pattern can satisfy the first sensing performance requirements for each sensing direction as follows: the sensing performance of the signals transmitted / received according to the first resource pattern is such that the main lobe width A1' in the zero-delay-Doppler direction is less than or equal to A1, the main lobe width A2' in the zero-Doppler-delay direction is less than or equal to A2, and the main lobe width A3' in the delay-Doppler 45° intersection direction is less than or equal to A3; the side lobe height B1' in the zero-delay-Doppler direction is less than or equal to B1, the side lobe height B2' in the zero-Doppler-delay direction is less than or equal to B2, and the side lobe height B3' in the delay-Doppler 45° intersection direction is less than or equal to B3; the ambiguity C1' in the zero-delay-Doppler direction is greater than or equal to C1, the ambiguity C2' in the zero-Doppler-delay direction is greater than or equal to C2, and the ambiguity C3' in the delay-Doppler 45° intersection direction is greater than or equal to C3.

[0026] In the first aspect described above, the first communication device can configure a first resource pattern for the second communication device based on at least one sensing direction and the first sensing performance requirements corresponding to each sensing direction. In this way, the sensing performance of the signals transmitted / received by the second communication device using the first resource pattern can meet the first sensing performance requirements. Because the first communication device only needs to configure the first resource pattern according to the corresponding sensing direction to meet the first sensing performance requirements, it does not need to configure resources comprehensively, thus reducing resource waste and improving resource utilization.

[0027] In one possible implementation, the first resource pattern is determined from a plurality of second resource patterns that satisfy the first perception performance requirements corresponding to each perception direction. The first resource pattern is the second resource pattern that uses the fewest resource particles among the plurality of second resource patterns.

[0028] In this application, the second resource pattern is determined based on information from at least one sensing direction and information on the first sensing performance requirement corresponding to each sensing direction. If there is one second resource pattern, then the first resource pattern is this second resource pattern. If there are multiple second resource patterns, the number of resource particles in different second resource patterns may be the same or different; if they are different, then the second resource pattern with the fewest resource particles is selected as the first resource pattern. If there are at least two second resource patterns with the fewest resource particles, then the second resource pattern with the best sensing performance is selected from these at least two second resource patterns with the fewest resource particles as the first resource pattern.

[0029] In this possible implementation, the first communication device selects the second resource pattern with the fewest resource particles from a plurality of second resource patterns that meet the first perception requirement as the first resource pattern. In this way, resource waste can be further reduced and resource utilization can be improved.

[0030] In one possible implementation, the method further includes: determining a first resource pattern based on information from at least one sensing direction and information on the first sensing performance requirements corresponding to each sensing direction.

[0031] In this possible implementation, the first communication device can determine the first resource pattern without the assistance of other nodes. This reduces the transmission overhead and latency caused by transmitting information about the sensing direction and the first sensing performance requirements corresponding to each sensing direction to other auxiliary nodes, thereby improving the speed of determining the first resource pattern.

[0032] In one possible implementation, determining a first resource pattern based on information from at least one sensing direction and information on a first sensing performance requirement corresponding to each sensing direction includes: determining a function slice diagram corresponding to each sensing direction based on the first sensing performance requirement corresponding to each sensing direction; wherein the function slice diagram corresponding to each sensing direction is used to indicate the distribution of sensing signals that satisfy the corresponding first sensing performance requirement; determining the distribution of one-dimensional resource particles corresponding to each sensing direction based on the function slice diagram corresponding to each sensing direction; and determining the first resource pattern based on the distribution of one-dimensional resource particles corresponding to each sensing direction.

[0033] In this application, the function slice diagram refers to the slice diagram corresponding to the fuzzy function in the corresponding sensing direction, wherein the commutative domain corresponding to the resource domain of the fuzzy function is related. Wherein:

[0034] The ambiguity function in the time-delay-Doppler domain characterizes the performance distribution of a signal (the autocorrelation function of the signal) in terms of time delay and frequency shift, that is, it characterizes the distribution of the signal in the time-delay-Doppler domain. The performance of the transmitted / received signal in the time-frequency domain can be measured by this ambiguity function in the time-delay-Doppler domain.

[0035] The ambiguity function in the angle domain characterizes the performance distribution of a signal in the azimuth-elevation direction. The performance of a signal transmitted / received on a two-dimensional antenna array can be measured by the ambiguity function in the angle domain.

[0036] The fuzzy function in the image domain characterizes the performance distribution of a signal in different directional components of the observation angle. The performance of a signal transmitted / received in the spatial and frequency domains along the direction of the observation angle can be measured by the fuzzy function in the image domain.

[0037] In this application, a library of function slice graphs can be used to maintain function slice graphs for perception performance corresponding to different perception directions. In this way, the corresponding function slice graph can be retrieved by the perception direction and the corresponding perception performance requirements.

[0038] In this possible implementation, the first communication device can determine the distribution of one-dimensional resource particles corresponding to each sensing direction based on the function slice diagram corresponding to each sensing direction; and determine the first resource pattern based on the distribution of one-dimensional resource particles corresponding to each sensing direction. This improves the accuracy of the first resource pattern.

[0039] In one possible implementation, determining a first resource pattern based on the distribution of one-dimensional resource particles corresponding to each sensing direction includes: back-projecting at least one second resource pattern based on the distribution of one-dimensional resource particles corresponding to each sensing direction; determining the first resource pattern based on the at least one second resource pattern; wherein, if there are multiple second resource patterns, the positional distribution of resource particles in the first resource pattern is such that the resource particles in the multiple second resource patterns have the least mutual occlusion when projected in at least one sensing direction.

[0040] In this application, the minimum amount of mutual occlusion between projections is the minimum amount of resource particles used.

[0041] In this possible implementation, one or more two-dimensional second resource patterns can be back-projected based on the distribution of one-dimensional resource particles corresponding to each sensing direction. Then, based on the projection occlusion between resource particles on the second resource patterns, the first resource pattern with the least projection occlusion, i.e., the one with the fewest resource particles, can be selected. This can improve the accuracy of determining the first resource pattern.

[0042] In one possible implementation, the method further includes: receiving information on available resource particles from a second communication device, wherein the information on available resource particles is used to determine a first resource pattern, and all resource particles corresponding to the first resource pattern are available resource particles.

[0043] In this possible implementation, the first communication device can assist in determining the first resource pattern based on the information of available resource particles sent by the second communication device, so that the positions of resource particles on the first resource pattern are all available resource particles. This can improve the accuracy of the first resource pattern and thus improve the sensing performance.

[0044] In one possible implementation, the resource configuration indication information includes indication information of the position of resource particles in the first resource pattern, information for determining the position of resource particles, or information for indicating the first resource pattern; wherein, the position of the resource particle is the position of the resource particle in the available resources, and the available resources include time-frequency resources, rooftop resources, or space-frequency resources.

[0045] In this application, the first resource pattern can be indicated in various forms, such as: indicating the position of the resource particle by the index, identifier or coordinate of the resource particle; or, indicating the position of the resource particle by various possible information for determining the position of the resource particle, such as the position of the starting resource particle, the offset value of other resource particles from the position of the starting resource particle, or the offset value of two adjacent resource particles; or, directly giving the pattern information of the first resource pattern.

[0046] This possible implementation provides a variety of possible forms of resource configuration instruction information, enriching the indication methods of the first resource pattern.

[0047] In one possible implementation, obtaining information about at least one sensing direction for sensing, and information about a first sensing performance requirement corresponding to each sensing direction, includes: receiving a first resource configuration request from a second communication device; wherein the first resource configuration request includes information about at least one sensing direction, and information about a first sensing performance requirement corresponding to each sensing direction.

[0048] In this possible implementation, by receiving information about at least one sensing direction and information about the first sensing performance requirements corresponding to each sensing direction from the second communication device, a first resource pattern that better meets the requirements of the second communication device can be determined, thereby improving the accuracy of the first resource pattern and thus improving the sensing performance.

[0049] In one possible implementation, before receiving the first resource configuration request from the second communication device, the method further includes: receiving a second resource configuration request from the second communication device; wherein the second resource configuration request includes information on at least one sensing direction and information on a second sensing performance requirement corresponding to each sensing direction, the second sensing performance requirement being higher than the first sensing performance requirement; and sending a configuration failure response to the second communication device, the configuration failure response indicating that no resource pattern satisfying the second sensing performance requirement was matched.

[0050] In this application, if the second perception performance requirement in the second resource configuration request sent earlier is too high, and the first communication device cannot match a resource pattern that meets the second perception performance requirement for the second communication device, a configuration failure response will be sent to the second communication device.

[0051] In this possible implementation, if the first communication device cannot find a resource pattern that meets the second sensing performance requirements, it can send a configuration failure response to the second communication device, which can then adjust the sensing performance requirements and complete the sensing process.

[0052] In one possible implementation, a configuration failure response is used to indicate a second perception performance requirement for adjusting the target perception direction, which is included in at least one perception direction.

[0053] In this possible implementation, the configuration failure response indicates the target sensing direction that needs to be adjusted for sensing performance requirements, which enables the second communication device to make accurate adjustments.

[0054] In one possible implementation, the resource pattern that does not meet the second perception performance requirement is obtained by back-projecting the distribution of one-dimensional resource particles corresponding to each perception direction.

[0055] In this possible implementation, if the resource pattern cannot be back-projected during the process of back-projecting a two-dimensional resource pattern through a one-dimensional resource particle distribution, it indicates that the configuration has failed.

[0056] A second aspect of this application provides a sensing method, comprising: receiving resource configuration indication information from a first communication device; wherein the resource configuration indication information is used to indicate a first resource pattern, the first resource pattern being determined based on information of at least one sensing direction and information of a first sensing performance requirement corresponding to each sensing direction, the first resource pattern satisfying the first sensing performance requirement corresponding to each sensing direction; and performing sensing based on the first resource pattern.

[0057] In the second aspect mentioned above, the second communication device uses the first resource pattern for sensing, which can not only meet the first sensing performance requirements, but also reduce the use of resources and improve resource utilization.

The first resource pattern is the second resource pattern that uses the fewest resource particles among the plurality of second resource patterns.

[0119] The embodiments of this application are described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. As those skilled in the art will understand, with the development of technology and the emergence of new scenarios, the technical solutions provided by the embodiments of this application are also applicable to similar technical problems.

[0120] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than that illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0121] This application provides a sensing method to achieve better sensing performance with fewer resources. This application also provides corresponding apparatus, computer-readable storage media, and computer program products. These will be described in detail below.

[0122] The technical solutions of this application can be applied to various communication systems, such as: satellite communication, 5th generation (5G) systems or new radio (NR), long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, universal mobile telecommunication systems (UMTS), vehicle to everything (V2X) communication systems, and future communication networks or systems after 5G networks, etc.

[0123] In addition to having stronger communication capabilities, the aforementioned communication system can also have sensing capabilities. It can be a communication system with integrated sensing and communication (ISAC). An integrated sensing and communication system means that the communication system can communicate through communication signals (which can also be described as communication channels) and perform sensing and measurement through sensing signals (which can also be described as sensing channels).

[0124] In this application, "perception" refers to using the transmission, reflection, and scattering of radio waves (radio frequency signals) to sense the surrounding environment and detect targets. For example, in vehicle-to-everything (V2X) systems, sensing signals are used to detect other vehicles or objects around vehicles; in imaging systems, sensing signals are used to image target points (buildings, vehicles, and other tangible objects) in the environment. Of course, the communication system in this application can also be an industrial automation system or other communication systems that require sensing.

[0125] The communication system described in this application can be a communication system based on orthogonal frequency division multiplexing (OFDM) and / or time division multiplexing (TDM), or a communication system or communication and sensing system based on frequency modulated continuous waveform (FMCW).

[0126] For ease of understanding, the technical terms involved in the embodiments of this application are briefly introduced below:

[0127] 1. Sensing Node: A communication device used for sensing, which may include a transmitter (Tx), a receiver (Rx), or a transceiver integrated communication device.

[0128] 2. Transmitter: A communication device that transmits communication signals and / or sensing signals (SS), also known as a transmitting node or transmitting device.

[0129] 3. Receiver: A communication device that receives the echo signal of communication signals and / or sensing signals; it may also be called a receiving node or receiving device.

[0130] 4. Sensing Signal: This refers to the radio frequency signal used to sense the environment or target. SS can be a sensing reference signal (SERS), a positioning reference signal (PRS), or a sounding reference signal (SRS), etc. Sensing signals can be transmitted in the form of beams.

[0131] 5. Echo signal (ES): refers to the signal after the sensing signal has been transmitted, reflected or scattered. The sensing result can be determined by measuring the echo signal, which can be received by beamforming.

[0132] 6. Beam: A beam is a communication resource. A beam can be wide, narrow, or other types of beams. The technology used to form a beam can be beamforming technology or other techniques. Beamforming technology can specifically be digital beamforming technology, analog beamforming technology, and hybrid digital or analog beamforming technology. Different beams can be considered different resources. The beam used to transmit signals can be called the transmission beam (Tx beam), and the beam used to receive signals can be called the reception beam (Rx beam). The transmission beam refers to the distribution of signal strength in different directions in space after the signal is transmitted through the antenna, and the reception beam refers to the distribution of signal strength in different directions in space of the wireless signal received from the antenna.

[0133] 7. Central node: refers to the communication device that configures sensing parameters for the transmitting end or receiving end of the sensing signal, and / or the communication device that summarizes the sensing results.

[0134] 8. The terms "system" and "network" in the embodiments of this application can be used interchangeably. "Multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the related objects before and after are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, "at least one of A, B, and C" includes A, B, C, AB, AC, BC, or ABC. And, unless otherwise specified, the ordinal numbers such as "first" and "second" mentioned in the embodiments of this application are used to distinguish multiple objects and are not used to limit the order, sequence, priority, or importance of multiple objects.

[0135] 9. In the embodiments of this application, "send" and "receive" indicate the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX, which may include sending directly via the air interface or sending indirectly via the air interface from other units or modules. "Receive information from YY" can be understood as the source of the information being YY, which may include receiving directly from YY via the air interface or receiving indirectly from YY via the air interface from other units or modules. "Send" can also be understood as the "output" of the chip interface, and "receive" can also be understood as the "input" of the chip interface.

[0136] In other words, sending and receiving can occur between devices, such as between network devices and terminal devices, or within a device, such as between components, modules, chips, software modules, or hardware modules within the device via buses, wiring, or interfaces.

[0137] It is understandable that information may undergo necessary processing, such as encoding and modulation, between the source and destination, but the destination can understand the valid information from the source. Similar statements in this application can be interpreted in a similar way and will not be elaborated further.

[0138] 10. In the embodiments of this application, "instruction" may include direct instruction and indirect instruction, as well as explicit instruction and implicit instruction. The information indicated by a certain piece of information (hereinafter referred to as instruction information) is called the information to be instructed. In the specific implementation process, there are many ways to indicate the information to be instructed, such as, but not limited to, directly indicating the information to be instructed, such as the information to be instructed itself or its index. It can also indirectly indicate the information to be instructed by indicating other information, where there is an association between the other information and the information to be instructed; or it can only indicate a part of the information to be instructed, while the other parts of the information to be instructed are known or pre-agreed upon. For example, the instruction of specific information can be achieved by using a pre-agreed (e.g., protocol predefined) arrangement order of various information, thereby reducing the instruction overhead to a certain extent. This application does not limit the specific method of instruction. It is understood that for the sender of the instruction information, the instruction information can be used to indicate the information to be instructed; for the receiver of the instruction information, the instruction information can be used to determine the information to be instructed.

[0139] In this application, unless otherwise specified, the same or similar parts between the various embodiments can be referred to each other. In the various embodiments of this application, and the various methods / designs / implementations within each embodiment, unless otherwise specified or logically conflicting, the terminology and / or descriptions between different embodiments and between the various methods / designs / implementations within each embodiment are consistent and can be mutually referenced. The technical features in different embodiments and the various methods / designs / implementations within each embodiment can be combined to form new embodiments, methods, or implementations based on their inherent logical relationships. The following descriptions of the embodiments of this application do not constitute a limitation on the scope of protection of this application.

[0140] The sensing method provided in this application can be applied to either a single sensing scenario or a joint sensing scenario. A single sensing scenario refers to a scenario where a single sensing node obtains the required sensing result after sensing. A joint sensing scenario refers to a scenario where multiple sensing nodes sense the same sensing area, and then each sensing node sends its own determined sensing result to a central node, which then fuses the multiple sensing results to reduce sensing uncertainty and improve sensing performance.

[0141] The individual or joint sensing scenarios involved in the embodiments of this application can be single-base sensing scenarios, dual-base sensing scenarios, or hybrid single-base and dual-base sensing scenarios. A dual-base sensing scenario refers to a sensing scenario where the transmitter of the sensing signal and the receiver of the echo signal are not the same communication device. A single-base sensing scenario refers to a sensing scenario where the transmitter of the sensing signal and the receiver of the echo signal belong to the same communication device; a single-base sensing scenario can also be called a self-sensing scenario. A hybrid dual-base and single-base sensing scenario refers to a sensing scenario in which the participating communication devices include both integrated transceiver communication devices and separate transceiver communication devices.

[0142] The dual-base sensing scenario can be understood by referring to Figure 1A. As shown in Figure 1A, this dual-base sensing scenario includes two transmitters, four receivers, and multiple target objects. The two transmitters are transmitter Tx101 and transmitter Tx102; the four receivers are receiver Rx103, receiver Rx104, receiver Rx105, receiver Rx106, and a central node 107; the target objects can be various types of buildings or other objects. The central node 107 can configure resources for the transmitters or receivers based on information from at least one sensing direction and the first sensing performance requirements corresponding to each sensing direction.

[0143] The transmitter Tx101 transmits a sensing signal SS1, and the echo signal ES1 generated by SS1 after passing through the building is received by the receiver Rx103.

[0144] Transmitter Tx102 transmits SS2, and SS2 passing through a building generates ES2, which is received by receiver Rx103; transmitter Tx102 transmits SS3, and SS3 passing through a building generates ES3, which is received by receiver Rx104; transmitter Tx102 transmits SS4, and SS4 passing through a building generates ES4, which is received by receiver Rx105; SS4 passing through a building generates ES5, which is received by receiver Rx106.

[0145] It should be noted that SS2, SS3, and SS4 can be sensing signals emitted from the same transmitting beam. However, sensing signals within the range of this transmitting beam will produce echo signals in different directions when encountering buildings at different locations, such as ES2, ES3, ES4, and ES5. Echo signals in different directions can be received by different receiving terminals. Of course, SS2, SS3, and SS4 can also be sensing signals in different beams of the transmitting terminal Tx102.

[0146] In a dual-base sensing scenario, echo signals generated by sensing signals transmitted from the same transmitter can be received by different receivers. For example, ES2 is received by receiver Rx103, ES3 by receiver Rx104, ES4 by receiver Rx105, and ES5 by receiver Rx106. Echo signals generated by sensing signals transmitted from different transmitters can also be received by the same receiver, such as ES1 and ES2 being received by receiver Rx103. Of course, echo signals generated by sensing signals transmitted from the same transmitter can also be received by only one receiver. This application does not limit the correspondence between transmitters and receivers; it is related to the number of transmitters or receivers within a certain area. In either case, the receiver can determine the sensing result based on its received echo signals. Alternatively, the receiver can send relevant data from the received echo signals to other communication devices for them to determine the sensing result.

[0147] The single-base sensing scenario can be understood with reference to Figure 1B. As shown in Figure 1B, the single-base sensing scenario may include a central node 107, sensing nodes 108, and multiple target objects. The sensing node 108 includes a transmitter of sensing signals and a receiver of echo signals. The central node 107 can configure resources for the sensing node 108 based on information from at least one sensing direction and information on the first sensing performance requirements corresponding to each sensing direction.

[0148] It should be noted that the single-base sensing scenario can include multiple sensing nodes, not limited to the one shown in Figure 1B. When there are multiple sensing nodes, the central node 107 can also summarize the sensing results of multiple sensing nodes.

[0149] When sensing node 108 measures targets in the environment, it can emit one or more beams. The sensing signals SS on the one or more beams can detect targets at different locations. The sensing node then receives the corresponding echo signals ES, and can determine the sensing result based on the ES. Of course, sensing node 108 can also send relevant data from the received echo signals to other communication devices, which can then determine the sensing result.

[0150] In the scenarios described in Figures 1A and 1B above, the central node 107 can also be called a sensing function (SF) network element or a sensing management function (SMF) network element, etc.

[0151] In the scenarios described in Figures 1A and 1B above, the receiver, transmitter, and sensing node can all be terminal devices or network devices, and the central node can also be a terminal device or a network device. The receiver, transmitter, sensing node, and central node shown in Figures 1A and 1B are not limited to their specific forms.

[0152] In addition, the hybrid single-base and dual-base sensing scenario refers to a scenario that includes both the sensing process of the transmitter and receiver as shown in Figure 1A, and the sensing process of the sensing node as shown in Figure 1B.

[0153] The terminal equipment and network equipment of this application are described below.

[0154] Terminal equipment: can be a wireless terminal device capable of receiving network device scheduling and instruction information. The wireless terminal device can be a device that provides voice and / or data connectivity to the user, or a handheld device with wireless connectivity, or other processing device connected to a wireless modem.

[0155] Terminal devices can communicate with one or more core networks or the Internet via a radio access network (RAN). Terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones), computers, and data cards. For example, they can be portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the RAN. Examples include personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), tablets, and computers with wireless transceiver capabilities. Wireless terminal equipment can also be called subscriber unit, subscriber station, mobile station (MS), remote station, access point (AP), remote terminal, access terminal, user terminal, user agent, subscriber station (SS), customer premises equipment (CPE), terminal, user equipment (UE), mobile terminal (MT), etc.

[0156] By way of example and not limitation, in this embodiment, the terminal device can also be a wearable device. Wearable devices, also known as wearable smart devices or smart wearable devices, are a general term for devices that utilize wearable technology to intelligently design and develop everyday wearables, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not merely hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are feature-rich, large in size, and can achieve complete or partial functions without relying on a smartphone, such as smartwatches or smart glasses, as well as those that focus on a specific type of application function and require the use of other devices such as smartphones, such as various smart bracelets, smart helmets, and smart jewelry for vital sign monitoring.

[0157] Terminal devices can also be drones, robots, terminals in device-to-device (D2D) communication, vehicle-to-everything (V2X) communication, virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in telemedicine or telehealth services, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, etc.

[0158] Furthermore, terminal devices can also be terminal devices in future communication systems beyond the fifth generation (5G) (such as 5G Advanced communication systems) or in future evolved public land mobile networks (PLMNs). For example, 5G Advanced networks can further expand the form and function of 5G communication terminals; 5G Advanced terminals include, but are not limited to, vehicles, cellular network terminals (integrating satellite terminal functions), drones, and Internet of Things (IoT) devices.

[0159] In this embodiment, the terminal device can also obtain artificial intelligence (AI) services provided by the network device. Optionally, the terminal device can also have AI processing capabilities.

[0160] Network equipment: This can be any device within a wireless network. For example, a network device can be a RAN node (or device) that connects terminal devices to the wireless network, and can also be called a base station. Currently, some examples of RAN equipment include: base stations, evolved NodeBs (eNodeBs), gNBs (gNodeBs) in 5G communication systems, transmission reception points (TRPs), evolved Node Bs (eNBs), radio network controllers (RNCs), Node Bs (NBs), home base stations (e.g., home evolved Node Bs, or home Node Bs (HNBs), base band units (BBUs) or wireless fidelity (Wi-Fi) access points (APs), terminals that function as base stations in device-to-device (D2D) communication, satellites, drones, unmanned spacecraft, communication balloons, and other non-ground equipment. In addition, in one network architecture, network devices may include central unit (CU) nodes, distributed unit (DU) nodes, or RAN devices that include both CU and DU nodes.

[0161] Optionally, the RAN node can also be a macro base station, micro base station, indoor station, relay node, donor node, or a radio controller in a cloud radio access network (CRAN) scenario. The RAN node can also be a server, wearable device, vehicle, or in-vehicle equipment. For example, the access network equipment in vehicle-to-everything (V2X) technology can be a roadside unit (RSU).

[0162] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, with different RAN nodes each implementing some of the base station's functions. For example, RAN nodes can be CUs, DUs, CUs (control plane, CP), CUs (user plane, UP), or radio units (RUs). CUs and DUs can be configured separately or included in the same network element, such as a baseband unit (BBU). RUs can be included in radio equipment or radio units, such as remote radio units (RRUs), active antenna units (AAUs), radio heads (RHs), or remote radio heads (RRHs).

[0163] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an open access network (open RAN, O-RAN, or ORAN) system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software modules and hardware modules.

[0164] Communication between access network devices and terminal devices follows a specific protocol layer structure. This protocol layer may include a control plane protocol layer and a user plane protocol layer. The control plane protocol layer may include at least one of the following: radio resource control (RRC) layer, packet data convergence protocol (PDCP) layer, radio link control (RLC) layer, media access control (MAC) layer, or physical (PHY) layer, etc. The user plane protocol layer may include at least one of the following: service data adaptation protocol (SDAP) layer, PDCP layer, RLC layer, MAC layer, or physical layer, etc.

[0165] The correspondence between network elements and their achievable protocol layer functions in the ORAN system can be found in Table 1 below.

[0166] Table 1

[0167] Network devices can be other devices that provide wireless communication functions for terminal devices. The embodiments of this application do not limit the specific technology or form of the network device. For ease of description, the embodiments of this application are not limited.

[0168] Network equipment may also include core network equipment, such as the Mobility Management Entity (MME), Home Subscriber Server (HSS), Serving Gateway (S-GW), Policy and Charging Rules Function (PCRF), and Public Data Network Gateway (PDN gateway or P-GW) in 4th generation (4G) networks; and access and mobility management function (AMF), user plane function (UPF), or session management function (SMF) in 5G networks. Furthermore, this core network equipment may also include other core network equipment in 5G networks and next-generation networks of 5G networks.

[0169] In this embodiment of the application, the network device may also have network nodes with AI capabilities, which can provide AI services to terminal devices or other network devices. For example, it may be an AI node, computing power node, RAN node with AI capabilities, core network element with AI capabilities, etc. on the network side (access network or core network).

[0170] The sensing method provided in this application embodiment is described below from the perspective of a first communication device and a second communication device. The first communication device can refer to the device itself, a component within the device (e.g., a processor, circuit, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the first communication device. The circuit or chip responsible for communication functions may be a modem chip (also known as a baseband chip), a system-on-a-chip (SoC) chip containing a modem core, or a system-in-package (SIP) chip. The device can be a network device or a terminal device, and the network device may include access network equipment or core network equipment. The second communication device can refer to the device itself, a component within the device (e.g., a processor, circuit, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the second communication device. The circuit or chip responsible for communication functions may be a modem chip (also known as a baseband chip), a system-on-a-chip (SoC) chip containing a modem core, or a system-in-package (SIP) chip. The device can be an access network device or a terminal device.

[0171] The first communication device can be a central node, an SF network element / SMF network element, a transmitting node (transmitter), or a receiving node (receiver), etc. The second communication device can be a device corresponding to a transmitting node (transmitter), a receiving node (receiver), or a sensing node.

[0172] As shown in Figure 2, the sensing method provided in this application embodiment includes:

[0173] S201. The first communication device acquires information about at least one sensing direction for sensing, and information about a first sensing performance requirement corresponding to each sensing direction.

[0174] In this application, if there is only one sensing direction, the first resource configuration request includes information about the sensing direction and information about the first sensing performance requirement corresponding to that sensing direction.

[0175] In this application, the first communication device may receive information about at least one sensing direction and information about the first sensing performance requirements corresponding to each sensing direction from the core network or the second communication device. Alternatively, the first communication device may determine information about at least one sensing direction and information about the first sensing performance requirements corresponding to each sensing direction on its own.

[0176] In this application, the information of the sensing direction is used to indicate the sensing direction. The sensing direction can be a sensing direction in the resource domain or a direction in the transform domain, where the transform domain refers to the domain after the Fourier transform of the resource domain.

[0177] In this application, the resource domain may include the time-frequency domain, the antenna domain, or the spatial-frequency domain. The time-frequency domain refers to the resource domain formed by time-domain resources and frequency-domain resources. The antenna domain refers to the resource domain formed by the spatial resources of the two-dimensional antenna array, such as the spatial resources provided by the two-dimensional antenna array in the azimuth direction and the spatial resources provided in the elevation direction. The spatial-frequency domain refers to the resource domain formed by the spatial resources and frequency resources provided by the antenna array. For example, the resource domain formed by the spatial resources and frequency resources provided by the antenna array in the observation angle direction, where the observation angle refers to the angle of the observed target point / target area center point relative to the transmitting node and / or receiving node.

[0178] In this application, the transform domain of the time-frequency domain can be the time-delay-Doppler domain. The image in the time-delay-Doppler domain characterizes the distribution of signals transmitted / received through time-domain and frequency-domain resources in the time-delay-Doppler direction. The performance of signals transmitted / received through time-domain and frequency-domain resources can be measured using this image. In this application, the transmitted signal refers to the sensed signal, and the received signal refers to the echo signal corresponding to the sensed signal.

[0179] In this application, the transformation domain of the rooftop domain can be the angle domain, such as the azimuth-elevation domain. The image in the azimuth-elevation domain characterizes the distribution of the signal transmitted / received by the two-dimensional antenna array in the azimuth-elevation direction. The performance of the signal transmitted / received by the two-dimensional antenna array can be measured through the image in the azimuth-elevation domain.

[0180] In this application, the transform domain of the spatial-frequency domain can be the image domain; the image in the image domain characterizes the performance of the signal transmitted / received through the spatial and frequency domain resources in the direction of the observation angle, and the image can measure the performance of the signal at different components of the observation angle.

[0181] In this application, the sensing direction can be at least one of the following: a time-frequency domain direction, a two-dimensional antenna array direction, or an antenna array-frequency domain direction in the resource domain; or, the sensing direction can be at least one of the following: a time-delay-Doppler direction, an azimuth-elevation direction, or a frequency component direction in the transform domain. Taking the time-delay-Doppler direction as an example, the sensing direction can include one or more time-delay-Doppler directions, such as: a zero-delay-Doppler direction, a zero-Doppler-time-delay and a 45° time-delay-Doppler intersection direction, etc. Of course, the time-delay-Doppler directions listed here are just examples; in reality, there can be many more time-delay-Doppler directions, and other types of sensing directions can also be one or more.

[0182] In this application, the information regarding the first sensing performance requirement is used to indicate the first sensing performance requirement. This requirement information may include one or more parameters indicating sensing performance, such as: the main lobe width of the ambiguity function, the side lobe height of the ambiguity function (e.g., peak-to-sidelobe ratio (PSLR) or integrated sidelobe ratio (ISLR)), or at least one of ambiguity-free characteristics. The main lobe width and side lobe height of the ambiguity function refer to resolution performance. Resolution refers to the minimum interval in the imaging result that can distinguish adjacent targets, such as distance interval or angular interval, which determines the fineness of the imaging and the target discrimination ability. Ambiguity-free characteristics refer to the range within which the imaging result will not produce confusion or repetition when measuring distance, angle, or velocity; it is used to ensure the accuracy and reliability of the measurement and avoid confusion and misunderstanding of target information. Of course, the information regarding the first sensing performance requirement may also include signal-to-interference-plus-noise ratio (SINR), gain, etc., which are not limited in this application.

[0183] In this application, the information of the first sensing performance requirement corresponding to each sensing direction refers to one or more parameters for indicating the first sensing performance requirement corresponding to each sensing direction, such as one or more parameters for indicating sensing performance corresponding to the zero-latency-Doppler direction, one or more parameters for indicating sensing performance corresponding to the zero-Doppler-latency direction, and one or more parameters for indicating sensing performance corresponding to the latency-Doppler 45° cross direction.

[0184] S202. The first communication device sends resource configuration instruction information to the second communication device; wherein the resource configuration instruction information is used to indicate a first resource pattern. Correspondingly, the second communication device receives the resource configuration instruction information.

[0185] The first resource pattern is used for sensing by the second communication device, and the first resource pattern satisfies the first sensing performance requirements corresponding to each sensing direction.

[0186] In this application, the first resource pattern refers to the distribution of resource particles within the resource domain described above. Here, a resource particle refers to a unit of resource division within the corresponding resource domain. For example:

[0187] In the time-frequency domain, the first resource pattern refers to the distribution of resource particles formed by time-domain resources and frequency-domain resources. Resource particles in the time-frequency domain can be resource elements (REs), or resource blocks (RBs) or other time-frequency resource partitioning units. This application does not limit this.

[0188] In the sky domain, the first resource pattern refers to the distribution of resource particles formed by a two-dimensional antenna array. The resource particles on the two-dimensional antenna array can be antenna elements or antenna ports.

[0189] In the spatial-frequency domain, the first resource pattern refers to the distribution of spatial and frequency domain resource blocks at different components of the observation angle. The resource particle represents the unit of spatial and frequency domain resources at different components of the observation angle. For example: f x =fsinθ,f y = fcosθ, where θ is the observation angle, i.e., the angle of the observed target point / target region center point relative to the transmitting node and / or receiving node, and f represents the frequency of the frequency domain resource. x f represents the frequency domain resource in the x-axis direction. y This represents the component of the frequency domain resource along the y-axis.

[0190] In this application, the first resource pattern satisfying the first perception performance requirement corresponding to each perception direction means that the performance of the signal sent / received on the resource particle indicated by the first resource pattern can reach or exceed the first perception performance requirement corresponding to each perception direction, such as: the actual resolution in each perception direction is better than the required resolution indicated by the first perception performance requirement and / or the actual ambiguity is better than the required ambiguity indicated by the first perception performance requirement. For example: In the information of the first sensing performance requirement: the main lobe width of the ambiguity function corresponding to the zero-delay-Doppler direction is A1, the side lobe height of the ambiguity function is B1, and the ambiguity is C1; the main lobe width of the ambiguity function corresponding to the zero-Doppler-delay direction is A2, the side lobe height of the ambiguity function is B2, and the ambiguity is C2; the main lobe width of the ambiguity function corresponding to the delay-Doppler 45° intersection direction is A3, the side lobe height of the ambiguity function is B3, and the ambiguity is C3; in this case, the first resource pattern can satisfy the first sensing performance requirement for each sensing direction as follows: the actual sensing performance of the signal sent / received according to the first resource pattern in the zero-delay-Doppler direction has a main lobe width A1' less than... The main lobe width A2' in the zero Doppler-time delay direction is less than or equal to A2, and the main lobe width A3' in the time delay-Doppler 45° cross direction is less than or equal to A3; the actual side lobe height B1' in the zero time delay-Doppler direction is less than or equal to B1, the side lobe height B2' in the zero Doppler-time delay direction is less than or equal to B2, and the side lobe height B3' in the time delay-Doppler 45° cross direction is less than or equal to B3; the actual unambiguity C1' in the zero time delay-Doppler direction is greater than or equal to C1, the unambiguity C2' in the zero Doppler-time delay direction is greater than or equal to C2, and the unambiguity C3' in the time delay-Doppler 45° cross direction is greater than or equal to C3.

[0191] S203. The second communication device senses the first resource map.

[0192] The sensing process may include sending sensing signals, receiving echo signals, and processing the echo signals to obtain sensing results.

[0193] In the solution provided in this application embodiment, the first communication device can configure a first resource pattern for the second communication device according to at least one sensing direction and the first sensing performance requirements corresponding to each sensing direction. In this way, the sensing performance of the signals transmitted / received by the second communication device using the first resource pattern can meet the first sensing performance requirements. Because the first communication device only needs to configure the first resource pattern according to the corresponding sensing direction to meet the first sensing performance requirements, it does not need to configure resources in all directions, which can reduce resource waste and improve resource utilization.

[0194] For an understanding of the resource patterns in the resource domain and the signal distribution in the transform domain described above, please refer to the following examples.

[0195] As shown in Figure 3A, in the time-frequency domain, resource particles are the units that divide time-domain resources and frequency-domain resources, such as REs (Resource Elements). In the resource pattern shown on the left side of Figure 3A, each square represents the location of an RE. White square 301 represents REs not needed for transmitting / receiving signals, while black square 302 represents REs used to carry signals. If signals are transmitted / received according to the resource pattern shown on the left side of Figure 3A, the two-dimensional distribution of the signal in the time-frequency domain corresponding to the delay-Doppler domain is shown on the right side of Figure 3A.

[0196] As shown in Figure 3B, in the sky domain, resource particles are the dividing units of a two-dimensional antenna array, which can be array elements or antenna ports. In the resource pattern shown on the left side of Figure 3B, each square represents the location of an antenna port. Among them, white square 303 represents antenna ports that are not used when transmitting / receiving signals, and black square 304 represents antenna ports used to carry signals. If signals are transmitted / received according to the resource pattern shown on the left side of Figure 3B, the two-dimensional distribution of the signal in the angular domain corresponding to the sky domain is shown on the right side of Figure 3B.

[0197] As shown in Figure 3C, in the spatial-frequency domain, resource particles are the units that divide spatial and frequency domain resources, and can be spatial-frequency resource blocks. In the resource pattern shown on the left side of Figure 3C, each square represents a spatial-frequency resource block. Among them, white squares 305 represent spatial-frequency resource blocks that are not needed when transmitting / receiving signals, and black squares 306 represent spatial-frequency resource blocks used to carry signals. If signals are transmitted / received according to the resource pattern shown on the left side of Figure 3C, the two-dimensional distribution of the signal in the image domain corresponding to the spatial-frequency domain is shown on the right side of Figure 3C.

[0198] Based on the relationship between the resource pattern of the resource domain and the signal distribution of the switching domain, another sensing method provided by the embodiments of this application is introduced.

[0199] As shown in Figure 4, the sensing method provided in this application embodiment includes:

[0200] S401. The second communication device sends a first resource configuration request to the first communication device; wherein the first resource configuration request includes information on at least one sensing direction, and information on the first sensing performance requirements corresponding to each sensing direction. Correspondingly, the first communication device receives the first resource configuration request.

[0201] If there is only one sensing direction, the first resource configuration request includes information about the sensing direction and information about the first sensing performance requirement corresponding to that sensing direction.

[0202] S402. The second communication device sends capability information to the first communication device. Correspondingly, the first communication device receives the capability information.

[0203] In this application, capability information may include the number, location, and orientation of antenna elements. The antenna elements may include the number and orientation of antenna elements used for transmitting signals, or the number and orientation of antenna elements used for receiving signals. Capability information may also include time-frequency resource information, such as bandwidth, carrier wave, and time slot.

[0204] In this application, the capability information includes information on available resource particles, which includes the index or location information of resource particles that can be used by the second communication device.

[0205] S402 can be an optional step. If the first communication device has already obtained the capability information of the second communication device in advance, then S402 can be omitted.

[0206] S403. The first communication device determines a first resource pattern based on information from at least one sensing direction and information on the first sensing performance requirements corresponding to each sensing direction.

[0207] The first communication device will also combine the capability information of the second communication device to determine the first resource pattern, so that the positions of resource particles on the first resource pattern are all available resource particles. This can improve the accuracy of the first resource pattern and thus improve the perception performance.

[0208] S404. The first communication device sends resource configuration instruction information to the second communication device. Correspondingly, the second communication device receives the resource configuration instruction information.

[0209] The resource configuration indication information includes indication information of the position of resource particles in the first resource pattern, such as: indicating the position of resource particles by index, identifier or coordinates of resource particles; or, the resource configuration indication information includes information for determining the position of resource particles, wherein the information for determining the position of resource particles may include the position of the starting resource particle, the offset value of other resource particles from the position of the starting resource particle, or the offset value of two adjacent resource particles, etc.; or, the pattern information of the first resource pattern is directly given.

[0210] In this embodiment of the application, the resource configuration indication information may also include information such as working cycle and signal gain. In this way, the second communication device can determine the usage time of the first resource pattern according to the working cycle and determine the power adjustment magnitude according to the signal gain.

[0211] The resource configuration indication information in this application can be sent via radio resource control (RRC) messages, downlink control information (DCI), uplink control information (UCI), medium access control element (MAC CE), or other Xn interfaces.

[0212] The solution provided in this application embodiment allows the first communication device to determine the first resource pattern without the assistance of other nodes. This reduces the transmission overhead and latency caused by transmitting information about the sensing direction and the first sensing performance requirements corresponding to each sensing direction to other auxiliary nodes, thereby improving the determination speed of the first resource pattern.

[0213] Optionally, S403 above includes:

[0214] S4031. The first communication device determines the function slice diagram corresponding to each sensing direction based on the first sensing performance requirements corresponding to each sensing direction.

[0215] In this context, the function slice diagram corresponding to each sensing direction is used to indicate the distribution of sensing signals that meet the corresponding first sensing performance requirements.

[0216] In this application, the function slice diagram refers to the slice diagram corresponding to the fuzzy function in the corresponding sensing direction, wherein the commutative domain corresponding to the resource domain of the fuzzy function is related. Wherein:

[0217] The ambiguity function in the time-delay-Doppler domain characterizes the performance distribution of a signal (the autocorrelation function of the signal) in terms of time delay and frequency shift, that is, it characterizes the distribution of the signal in the time-delay-Doppler domain. The performance of the transmitted / received signal in the time-frequency domain can be measured by this ambiguity function in the time-delay-Doppler domain.

[0218] The ambiguity function in the angle domain characterizes the performance distribution of a signal in the azimuth-elevation direction. The performance of a signal transmitted / received on a two-dimensional antenna array can be measured by the ambiguity function in the angle domain.

[0219] The fuzzy function in the image domain characterizes the performance distribution of a signal in different directional components of the observation angle. The performance of a signal transmitted / received in the spatial and frequency domains along the direction of the observation angle can be measured by the fuzzy function in the image domain.

[0220] In this application, a library of function slice graphs can be used to maintain function slice graphs for perception performance corresponding to different perception directions. In this way, the corresponding function slice graph can be retrieved by the perception direction and the corresponding perception performance requirements.

[0221] Taking the directions of the sensed signal, including the zero-delay-Doppler direction, the zero-Doppler-delay direction, and the delay-Doppler 45° intersection direction, as an example, the corresponding function slice diagram can be determined using the zero-delay-Doppler direction and the first sensing performance requirement corresponding to the zero-delay-Doppler direction, namely, the function slice diagram 501 corresponding to the first sensing performance requirement in the zero-delay-Doppler direction shown in Figure 5A; the corresponding function slice diagram can be determined using the zero-Doppler-delay direction and the first sensing performance requirement corresponding to the zero-Doppler-delay direction, namely, the function slice diagram 502 corresponding to the first sensing performance requirement in the zero-Doppler-delay direction shown in Figure 5A; the corresponding function slice diagram can be determined using the delay-Doppler 45° intersection direction and the first sensing performance requirement corresponding to the delay-Doppler 45° intersection direction, namely, the function slice diagram 503 corresponding to the first sensing performance requirement in the delay-Doppler 45° intersection direction shown in Figure 5A.

[0222] It should be noted that if the primary perception performance requirement includes multiple parameters indicating perception performance, such as the main lobe width and side lobe height of the fuzzy function (which are related to resolution), as well as fuzziness-free status, the function slice can be selected based on the priority of these different perception performance parameters. For example, if the main lobe width of the fuzzy function has the highest priority, the function slice can be selected according to the main lobe width; if the side lobe height of the fuzzy function has the highest priority, the function slice can be selected according to the side lobe height; and if fuzziness-free status has the highest priority, the function slice can be selected according to fuzziness-free status.

[0223] S4032. The first communication device determines the distribution of one-dimensional resource particles corresponding to each sensing direction based on the function slice diagram corresponding to each sensing direction.

[0224] The S4032 can be understood by referring to Figure 5A. As shown in Figure 5A, the distribution of one-dimensional resource particles when t=0 can be determined according to the function slice graph 501, that is, the one-dimensional particle distribution graph 504 in Figure 5A; the distribution of one-dimensional resource particles when f=0 can be determined according to the function slice graph 502, that is, the one-dimensional particle distribution graph 505 in Figure 5A; the distribution of one-dimensional resource particles when t and f intersect at 45° can be determined according to the function slice graph 503, that is, the one-dimensional particle distribution graph 506 in Figure 5A.

[0225] S4033. The first communication device performs back projection based on the distribution of one-dimensional resource particles corresponding to each sensing direction to obtain the back projection result.

[0226] In this application, there are three types of back projection results: back projection yields one second resource pattern, back projection yields multiple second resource patterns, or back projection does not yield a resource pattern.

[0227] Taking the distribution of one-dimensional resource particles in Figure 5A as an example, if the one-dimensional resource particles in these three sensing directions are back-projected, a two-dimensional resource pattern as shown in Figure 5B can be obtained. This example back-projection only yields a second resource pattern; therefore, the second resource pattern described in Figure 5B is the first resource pattern.

[0228] If the distribution of one-dimensional resource particles in the three sensing directions of the above example is as shown in 507 of Figure 5C, back-projection of 507 yields a second resource pattern 508 and a second resource pattern 509. By comparing the resource particle distributions of the second resource pattern 508 and the second resource pattern 509, it can be seen that the second resource pattern 508 uses fewer resource particles than the second resource pattern 509. Therefore, the second resource pattern 508 can be identified as the first resource pattern.

[0229] In the embodiments of this application, the method for obtaining resource patterns from one-dimensional resource particles by back-projection can use algorithms such as filtered back-projection (FBP) and algebraic reconstruction technique (ART).

[0230] In this embodiment, taking the second resource pattern 508 and the second resource pattern 509 as examples, although the one-dimensional projection shapes of the two resource patterns are the same in the three sensing directions of each of the above examples, the projection weights superimposed at different positions are different. For example, if the resource pattern is projected along a certain direction, multiple two-dimensional resource particles are projected onto the same position. At this time, the weight of the resource particle at that position is equal to the sum of the weights of the multiple resource particles. In this application, superposition can also be understood as occlusion between different resource particles, resulting in resource waste. Therefore, the more uniform the weight of the two-dimensional resource particle projection, the higher the resource utilization rate and the better the sensing performance. Therefore, when multiple second resource patterns are obtained by backprojection as shown in Figure 5C, the second resource pattern with the fewest resource particles can be selected as the first resource pattern, which can both meet the first sensing performance requirements and save resources.

[0231] Figures 5A to 5C illustrate the process of determining the corresponding one-dimensional resource particles using the time-delay-Doppler domain slice function graph, and then back-projecting the one-dimensional resource particles into a two-dimensional resource map in the time-frequency domain. Similarly, the principles for determining the corresponding one-dimensional resource particles using the azimuth-elevation angle domain slice function graph, and then back-projecting the one-dimensional resource particles into a two-dimensional resource map in the sky domain, or determining the corresponding one-dimensional resource particles using the image domain slice function graph, and then back-projecting the one-dimensional resource particles into a two-dimensional resource map in the space-frequency domain, are the same as those in Figures 5A to 5C, only the coordinate system parameters differ. Therefore, the process of obtaining two-dimensional resource maps in the sky domain or space-frequency domain can be understood by referring to the processes illustrated in Figures 5A to 5C.

[0232] If a resource pattern cannot be obtained through the above projection or a corresponding function slice pattern cannot be found through the first perception performance requirement in the corresponding perception direction, it means that the first communication device cannot match a resource pattern that meets the first perception performance requirement, and a configuration failure response can be sent to the second communication device.

[0233] For an understanding of the scenario where configuration failures occur, please refer to Figure 6. As shown in Figure 6, the perception method provided in this application embodiment includes:

[0234] S601. The second communication device sends a second resource configuration request to the first communication device; wherein the second resource configuration request includes information on at least one sensing direction, and information on the second sensing performance requirements corresponding to each sensing direction. Correspondingly, the first communication device receives the second resource configuration request.

[0235] The second perception performance requirement is higher than the first perception performance requirement.

[0236] S602. The second communication device sends capability information to the first communication device. Correspondingly, the first communication device receives the capability information.

[0237] This step can be understood by referring to S402.

[0238] S603. The first communication device determines a resource pattern based on information from at least one sensing direction and information from the second sensing performance requirements corresponding to each sensing direction.

[0239] This process can occur when the first communication device, based on information from at least one sensing direction and the corresponding second sensing performance requirements for each sensing direction, cannot find the corresponding slice function graph in the slice function graph library, or cannot back-project the resource pattern. These situations are usually caused by excessively high second sensing performance requirements, necessitating a reduction in those requirements.

[0240] S604. The first communication device sends a configuration failure response to the second communication device. Correspondingly, the second communication device receives the configuration failure response.

[0241] The configuration failure response is used to indicate that no resource pattern that meets the second-perceived performance requirements was matched.

[0242] The configuration failure response can be used to indicate a second sensing performance requirement for adjusting the target sensing direction, where the target sensing direction is included in at least one sensing direction. Because the configuration failure response specifies the target sensing direction for which the sensing performance requirement needs adjustment, the second communication device can make accurate adjustments.

[0243] S605. The second communication device adjusts the information of the second sensing performance requirement to the information of the first sensing performance requirement.

[0244] If only the second perception performance requirement is too high in the target perception direction, and the second perception performance requirements in other perception directions can be matched with the corresponding slice function graph, then only the information regarding the second perception performance requirement in the target perception direction needs to be adjusted. The second perception performance requirements in other perception directions can be understood as the first perception performance requirements.

[0245] S606. The second communication device sends a first resource configuration request to the first communication device; correspondingly, the first communication device receives the first resource configuration request.

[0246] In this scenario, the first resource configuration request may include information about at least one sensing direction, as well as information about the first sensing performance requirements corresponding to each sensing direction; alternatively, it may only include information about the first sensing performance requirements for the target sensing direction. This reduces the amount of data transmitted.

[0247] S607. The first communication device determines a first resource pattern based on information from at least one sensing direction and information on the first sensing performance requirements corresponding to each sensing direction.

[0248] This process can be understood by referring to the descriptions of S4031 to S4033 in S403.

[0249] S608. The first communication device sends resource configuration instruction information to the second communication device. Correspondingly, the second communication device receives the resource configuration instruction information.

[0250] This resource configuration instruction information can be understood by referring to the introduction in section S404.

[0251] In the event of a resource configuration failure, the first communication device can notify the second communication device to adjust the sensing performance requirements and complete the sensing process by responding to the configuration failure.

[0252] The above describes the sensing method of this application from the perspective of the first communication device and the second communication device. The interaction process between the first communication device and the second communication device will be described below in different scenarios.

[0253] As shown in Figure 7, taking a bi-base sensing scenario where the first communication device is a central node, an SF network element, or an SMF network element, and the second communication device is both a transmitting node and a receiving node as an example, the sensing method provided in this application embodiment includes:

[0254] S701. The transmitting node and the receiving node send a first resource configuration request to the central node / SF network element / SMF network element. Correspondingly, the central node / SF network element / SMF network element receives the first resource configuration request.

[0255] The first resource configuration request includes information on at least one sensing direction, as well as information on the first sensing performance requirements corresponding to each sensing direction.

[0256] S702. Transmitting and receiving nodes send capability information to the central node / SF network element / SMF network element.

[0257] The capability information transmitted by the transmitting node includes information about the available resource particles of the transmitting node; the capability information transmitted by the receiving node includes information about the available resource particles of the receiving node.

[0258] Of course, the capability information may also include information as described in the corresponding section of S402 above, which can be understood by referring to the preceding introduction.

[0259] S703. The central node / SF network element / SMF network element determines the first resource pattern based on information from at least one sensing direction and information on the first sensing performance requirements corresponding to each sensing direction.

[0260] The relevant content in S7031 to S7033 can be understood by referring to S4031 to S4033.

[0261] S704a. The central node / SF network element / SMF network element sends resource configuration instruction information to the transmitting node. Correspondingly, the transmitting node receives the resource configuration instruction information.

[0262] S704b. The central node / SF network element / SMF network element sends resource configuration instruction information to the receiving node. Correspondingly, the receiving node receives the resource configuration instruction information.

[0263] In this application, the first resource patterns indicated by the resource configuration instruction information of S704a and S704b may be the same or different, and this application does not limit this.

[0264] S705. The transmitting node sends a sensing signal based on the first resource map.

[0265] S706. The receiving node receives the echo signal according to the first resource pattern.

[0266] In the solution provided in this application embodiment, the central node / SF network element / SMF network element can configure a first resource pattern for the transmitting node and the receiving node according to the sensing direction and the first sensing performance requirements corresponding to the sensing direction reported by the transmitting node and the receiving node. The sensing result that meets the first sensing performance requirements can be obtained with less resources, thereby improving resource utilization.

[0267] As shown in Figure 8, taking a single-base sensing scenario where the first communication device is a central node or an SF network element / SMF network element, and the second communication device is a sensing node as an example, the sensing method provided in this application embodiment includes:

[0268] S801. The sensing node sends a first resource configuration request to the central node / SF network element / SMF network element. Correspondingly, the central node / SF network element / SMF network element receives the first resource configuration request.

[0269] The first resource configuration request includes information on at least one sensing direction, as well as information on the first sensing performance requirements corresponding to each sensing direction.

[0270] S802. The sensing node sends capability information to the central node / SF network element / SMF network element.

[0271] The capability information sent by the sensing node includes information about available resource particles that emit sensing signals and information about available resource particles that receive echo signals.

[0272] Of course, the capability information may also include information as described in the corresponding section of S402 above, which can be understood by referring to the preceding introduction.

[0273] S803. The central node / SF network element / SMF network element determines the first resource pattern based on information from at least one sensing direction and information on the first sensing performance requirements corresponding to each sensing direction.

[0274] The relevant content in S8031 to S8033 can be understood by referring to S4031 to S4033.

[0275] S804. The central node / SF network element / SMF network element sends resource configuration instruction information to the sensing node.

[0276] S805. The sensing node sends a sensing signal based on the first resource map.

[0277] S806. The sensing node receives the echo signal according to the first resource map.

[0278] In the solution provided in this application embodiment, the central node / SF network element / SMF network element can configure a first resource pattern for the sensing node according to the sensing direction reported by the sensing node and the first sensing performance requirement corresponding to the sensing direction. The sensing result that meets the first sensing performance requirement can be obtained with less resources, thereby improving resource utilization.
