[0002] The present application relates to the field of communication technology, in particular to a sensing method and a corresponding apparatus. BACKGROUND

[0003] In a communication system integrated sensing and communication (ISAC), a transmitting end can transmit a sensing signal to scan an environment for a target, and a receiving end can obtain a sensing result by receiving a backscatter signal reflected or scattered by the target and performing sensing processing on the backscatter signal, and then making a decision or assisting the decision based on the sensing result. In order to improve the accuracy of the decision or the assisted decision, higher requirements are put forward for the sensing quality of the sensing result.

[0004] It is found that, if some joint configuration is performed on the transmitting end and the receiving end, and then a joint transmission and reception scanning is performed, better sensing gain can be obtained, and the sensing quality of the sensing result can be improved. As for the joint transmission and reception scanning scenario, if the scanning parameter configuration of the transmitting end is appropriate, better sensing gain can be obtained, and if the scanning parameter configuration of the transmitting end is inappropriate, the scanning overhead can be greatly increased, or false target points can appear in the imaging result.

[0005] Therefore, in the joint transmission and reception scanning scenario, how to configure appropriate scanning parameters for the transmitting end has become a technical problem to be solved. SUMMARY

[0006] The present application provides a sensing method for obtaining an imaging result with higher sensing quality at lower scanning overhead. The present application also provides a corresponding apparatus, a computer readable storage medium, and a computer program product, etc.

[0007] The first aspect of the present application provides a sensing method, comprising: obtaining scanning information of a transmitting beam corresponding to a first region; wherein the scanning information of the transmitting beam comprises a parameter for indicating a scanning interval, or the scanning information of the transmitting beam is determined through the scanning interval; wherein the scanning interval is determined through a first range, and the first range is determined through a first resolution, and the first resolution meets a resolution requirement of an imaging result of the first region; and transmitting a first beam according to the scanning information of the transmitting beam, the first beam being used for scanning the first region.

[0008] The perception method provided in the application can be applied to a first communication device, which can be a transceiver integrated perception node or a transmitting end of a perception signal. The first communication device can be a network device, a terminal device, or a chip in the network device or a chip in the terminal device, and the application does not limit the implementation.

[0009] In the application, the first area can be an area selected by a user, an area selected by the first communication device or the second communication device. The second communication device can be a center node, which can be a node configured with perception parameters for the transmitting end of the perception signal or the receiving end of the perception signal, and / or a node that aggregates perception results. The center node can be a network device or a chip in the network device, and of course, the center node can also be other forms of devices, such as a terminal device or a chip in the terminal device. The second communication device can also be a network element of a core network, such as a sensing management function (SMF) network element or a location management function (LMF) network element. The second communication device can also be the receiving end of the echo signal corresponding to the perception signal.

[0010] In the application, the scanning information of the transmitting beam can be used to generate a plurality of information of the transmitting beam (first beam). Each first beam scans a sub-area in the first area, and the sub-areas scanned by different first beams do not overlap. The plurality of information can include a scanning range in the azimuth direction, a scanning range in the elevation direction, a scanning interval, or a parameter for indicating the scanning interval, such as a multiple for indicating the scanning interval if the minimum scanning granularity is agreed, and the product of the multiple and the minimum scanning granularity is the scanning interval of the sub-area. The scanning interval refers to the angle (or position) interval between two adjacent transmitting beams, and the scanning intervals between different adjacent transmitting beams can be the same or different. The plurality of information can also include the transmission time of each first beam.

[0011] In the application, the first resolution can be selected by a user, and the first resolution meets the resolution requirement of the imaging result of the first area. In the perception scene, the meaning of resolution refers to the minimum interval, such as distance interval or angle interval, that can distinguish adjacent targets in the imaging result, which determines the degree of imaging precision and target distinguishing ability. The resolution requirement refers to the resolution that meets the set minimum interval, such as the minimum distance interval or the minimum angle interval.

[0012] In the first aspect, the first range is determined by the first resolution, so that the upper limit of the first range can satisfy the perception gain of the perception imaging, and the imaging result with better perception quality can be obtained by the upper limit of the first range. The lower limit of the first range can avoid infinitely reducing the scanning interval, and can effectively reduce the scanning overhead. Therefore, according to the scheme provided in the application, the scanning information of the transmission beam is determined by determining the scanning interval according to the first range, so that the imaging result with higher perception quality can be obtained, and the scanning overhead can be effectively reduced.

[0013] In a possible implementation, the first resolution is not greater than the second resolution, and the second resolution is a resolution determined by the transmission capability of the transmission end and the receiving capability of the receiving end.

[0014] In this possible implementation, the second resolution can be a theoretical value of the resolution determined according to the transmission capability of the transmission end and the receiving capability of the receiving end. The first resolution is not greater than the second resolution, that is, the first resolution is less than or equal to the second resolution, so that the transmission capability of the transmission end and the receiving capability of the receiving end can be used as much as possible, and the resource utilization rate of the transmission end and the receiving end can be improved.

[0015] In a possible implementation, the first range is associated with a perception algorithm, and the perception algorithm includes a perception algorithm based on solving or a perception algorithm based on matching.

[0016] In this possible implementation, the perception algorithm based on solving refers to a perception algorithm for determining an imaging result by solving, for example, a compressive sensing (CS) algorithm, which can determine an imaging result by calculating a solution space. The perception algorithm based on matching refers to a perception algorithm for determining an imaging result by matching filtering, for example, a digital beam forming (DBF) or a fast Fourier transform (FFT) algorithm, which can determine an imaging result by performing matching filtering processing on a return signal. In the application, the first range is associated with the perception algorithm, so that the accuracy of the first range used by different perception algorithms can be improved, and the perception quality of the imaging result can be improved.

[0017] In a possible implementation, the perception algorithm is a perception algorithm based on solving, and the first range is determined by the first resolution, the receiving capability of the receiving end, and the sparsity of a second region, and the sparsity of the second region is used to represent the number of targets in the second region. The second region is included in the first region.

[0018] In the application, the second region is a sub-region in the first region, and each second region corresponds to a transmission beam.

[0019] In the possible implementation, when the solving-based perception algorithm is used, the first range is not only related to the first resolution, but also related to the sparsity of the second region, that is, the number of targets in the second region, which is more conducive to determining the first range in combination with the number of targets, and the accuracy of the first range determination can be improved.

The upper limit of the first range is related to the number of receiving arrays of the receiving end and the sparsity, so that the scanning overhead can be considered on the basis of obtaining better perception performance.

[0023] In the possible implementation, the second resolution is a theoretical value of the resolution determined by the transmission capability of the transmitting end and the receiving capability of the receiving end. A suitable range is taken on the theoretical value to determine the scanning interval, so that better perception performance can be obtained, and the scanning overhead can be considered.

[0033] The scanning interval of adjacent beams is determined according to the size of the second region, and the scanning interval of adjacent beams is used to determine the scanning information of the transmission beam corresponding to the first region.

[0034] In this possible implementation, the second resolution is determined first, and then the first resolution is determined, so that the utilization rate of the resources of the transmission end and the reception end can be improved, and then the first range is determined according to the first resolution, and the scanning information of the transmission beam is determined, so that better sensing performance can be obtained, and the scanning overhead can also be considered.

[0036] In the second aspect, the first range is determined through the first resolution, so that the upper limit of the first range can meet the perception gain of the perception imaging, and the imaging result with better perception quality can be obtained through the upper limit of the first range. The lower limit of the first range can avoid infinitely reducing the scanning interval, and can effectively reduce the scanning overhead.

[0122] 13. The terms "system" and "network" in the embodiments of the present application can be used interchangeably. "Multiple" refers to two or more. "And / or", which describes the association relationship of the associated objects, means that there can be three relationships, for example, A and / or B can represent the cases of A alone, A and B together, and B alone, where A and B can be singular or plural. The character " / " generally represents an "or" relationship between the associated objects before and after it. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single item or multiple items. For example, "at least one of A, B and C" includes A, B, C, AB, AC, BC or ABC. In addition, unless otherwise specified, the ordinal numbers "first", "second", etc. mentioned in the embodiments of the present application are used to distinguish multiple objects, and are not used to limit the order, time sequence, priority or importance of the multiple objects.

[0123] 14. "Sending" and "receiving" in the embodiments of the present application represent the direction of signal transmission. For example, "sending information to XX" can be understood as that the destination of the information is XX, which can include direct sending through the air interface, and also includes indirect sending through the air interface by other units or modules.

[0125] It can be understood that the information may be processed as necessary between the source and the destination of the information transmission, such as encoding, modulation, etc., but the destination can understand the valid information from the source.

The information indicated by certain information (indication information described below) is referred to as to-be-indicated information. In the implementation process, there are many ways to indicate the to-be-indicated information, for example, but not limited to, the to-be-indicated information can be directly indicated, such as the to-be-indicated information itself or an index of the to-be-indicated information. The to-be-indicated information can also be indirectly indicated by indicating other information, where the other information and the to-be-indicated information have an association relationship. The to-be-indicated information can also be indicated only by a part of the to-be-indicated information, and the other part of the to-be-indicated information is known or agreed in advance. For example, the indication of a specific information can be achieved by means of the arrangement order of each information agreed in advance (for example, protocol predefined), thereby reducing the indication overhead to a certain extent. The present application does not limit the specific manner of indication.

[0127] In the present application, the same or similar parts between various embodiments can be mutually referred to, unless otherwise specified. In various embodiments of the present application, and various methods / designs / implementation manners in each embodiment, the terms and / or descriptions between different embodiments, and between various methods / designs / implementation manners in each embodiment are consistent and can be mutually referred to, unless otherwise specified and logically conflicted. The technical features in different embodiments, and in various methods / designs / implementation manners in each embodiment can be combined to form new embodiments, methods, or implementation manners according to their inherent logical relationship. The implementation manners of the present application described below do not constitute a limitation on the protection scope of the present application.

[0128] The perception method provided by the embodiments of the present application can be applied to a single perception scene or a joint perception scene. The single perception scene refers to that a perception node perceives and then obtains a required perception result. The joint perception scene refers to that a same perception area is perceived by multiple perception nodes, and then the multiple perception nodes send multiple respective determined perception results to a center node, and the center node fuses the multiple perception results, thereby reducing the uncertainty of perception and improving the perception performance.

[0129] The single-perception scene or the joint-perception scene involved in the embodiments of the present application can be a single-base perception scene, a double-base perception scene, or a mixed perception scene of single base and double base. The double-base perception scene refers to a perception scene with separated transmission and reception, i.e., the transmission end of the perception signal and the reception end of the echo signal are not the same communication device. The single-base perception scene refers to a perception scene with integrated transmission and reception, i.e., the transmission end of the perception signal and the reception end of the echo signal belong to the same communication device, and the single-base perception scene can also be referred to as a self-perception scene. The mixed perception scene of double base and single base refers to a communication device participating in perception, which includes both a communication device with integrated transmission and reception and a communication device with separated transmission and reception.

[0130] The double-base perception scene can be understood with reference to FIG. 1A. As shown in FIG. 1A, the double-base perception scene includes two transmission ends, four reception ends, and multiple target objects. The two transmission ends are transmission end Tx101 and transmission end Tx102, the four reception ends are reception end Rx103, reception end Rx104, reception end Rx105, reception end Rx106, and center node 107, and the target objects can be various types of buildings or other objects. The center node 107 can configure the scanning information of the transmission beam for one or more transmission ends, and of course, the center node 107 can also configure the reception parameters for one or more reception ends. The center node 107 can also aggregate the perception results of multiple reception ends.

[0131] The transmission end Tx101 transmits a perception signal SS1, and the echo signal ES1 generated by the building is received by the reception end Rx103.

[0132] The transmission end Tx102 transmits SS2, and the echo signal ES2 generated by the building is received by the reception end Rx103; the transmission end Tx102 transmits SS3, and the echo signal ES3 generated by the building is received by the reception end Rx104; the transmission end Tx102 transmits SS4, and the echo signal ES4 generated by the building is received by the reception end Rx105, and the echo signal ES5 generated by the building is received by the reception end Rx106.

[0133] It should be noted that SS2, SS3, and SS4 can be perception signals transmitted by the same transmission beam, and the perception signals in the range of the transmission beam will generate echo signals in different directions when encountering buildings at different positions, such as ES2, ES3, ES4, and ES5. Different directions of the echo signals can be received by different reception ends. Of course, SS2, SS3, and SS4 can also be perception signals in different beams of the transmission end Tx102.

[0134] In the double-basis sensing scenario, echo signals generated by sensing signals transmitted by the same transmitting end can be received by different receiving ends, such as ES2 received by receiving end Rx103, ES3 received by receiving end Rx104, ES4 received by receiving end Rx105, and ES5 received by receiving end Rx106. Echo signals generated by sensing signals transmitted by different transmitting ends can also be received by the same receiving end, such as ES1 and ES2 both received by receiving end Rx103. Of course, echo signals generated by sensing signals transmitted by the same transmitting end can also be received only by the same receiving end. The correspondence between the transmitting end and the receiving end is not limited by the present application, and is related to the number of transmitting ends or receiving ends in a certain area. Regardless of which scenario, the receiving end can determine the sensing result according to the received echo signal, and of course, the receiving end can also send relevant data in the received echo signal to other communication devices, and the other communication devices determine the sensing result.

[0135] The single-basis sensing scenario can be understood with reference to FIG. 1B. As shown in FIG. 1B, the single-basis sensing scenario can include a center node 107, a sensing node 108, and a plurality of target objects. The sensing node 108 includes a transmitting end of a sensing signal and a receiving end of an echo signal. The center node 107 can configure the sensing node 108 with scanning information of a transmitting beam. It should be noted that the single-basis sensing scenario can include a plurality of sensing nodes, not limited to one as shown in FIG. 1B. When there are a plurality of sensing nodes, the center node 107 can also aggregate the sensing results of the plurality of sensing nodes.

[0136] When measuring target objects in an environment, the sensing node 108 can transmit one or more beams, and sensing signals SS on the one or more beams can detect target objects at different positions. Then the sensing node can receive corresponding echo signals ES, and further determine a sensing result according to the ES. Of course, the sensing node 108 can also send relevant data in the received echo signal to other communication devices, and the other communication devices determine the sensing result.

[0137] In the scenarios described in FIGS. 1A and 1B, the receiving end, the transmitting end, the sensing node, and the center node can be terminal devices or network devices. The receiving end, the transmitting end, the sensing node, and the center node shown in FIGS. 1A and 1B are not limited in their specific forms.

[0138] In addition, the single-basis and double-basis mixed sensing scenario refers to a scenario that includes both the sensing process of the transmitting end and the receiving end as shown in FIG. 1A and the sensing process of the sensing node as shown in FIG. 1B.

[0146] Network device: can be a device in a wireless network, for example, the network device can be a RAN node (or device) for accessing the terminal device to the wireless network, which can also be called a base station.

The RAN node can also be a server, a wearable device, a vehicle or a vehicle-mounted device, etc. For example, the access network device in vehicle external connection (V2X) technology can be a road side unit (road side unit, RSU).

[0148] In another possible scenario, multiple RAN nodes cooperate to assist a terminal to implement wireless access, and different RAN nodes respectively implement part of functions of a base station. For example, a RAN node can be a CU, a DU, a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be separately configured, or can be included in the same network element, for example, in a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, for example, in a remote radio unit (RRU), an active antenna unit (AAU), a radio head (RH), or a remote radio head (RRH).

[0149] In different systems, the CU (or CU-CP and CU-UP), the DU, or the RU can also have different names, but those skilled in the art can understand their meanings. For example, in an open RAN (O-RAN or ORAN) system, the CU can also be referred to as an O-CU (open CU), the DU can also be referred to as an O-DU, the CU-CP can also be referred to as an O-CU-CP, the CU-UP can also be referred to as an O-CU-UP, and the RU can also be referred to as an O-RU.

[0153] The network device can be another device that provides a wireless communication function for the terminal device. Embodiments of the present application do not limit the specific technology and specific device form adopted by the network device. For the convenience of description, embodiments of the present application do not limit.

[0154] The network device can also include a core network device, for example, a mobility management entity (MME) in a fourth generation (4G) network, a home subscriber server (HSS), a serving gateway (S-GW), a policy and charging rules function (PCRF), a public data network gateway (PDN gateway or P-GW), a network element such as an access and mobility management function (AMF) in a 5G network, a user plane function (UPF), or a session management function (SMF). In addition, the core network device can also include other core network devices in the 5G network and the next generation network of the 5G network.

[0155] In the embodiments of the present application, the network device mentioned above can also be an AI-capable network node, which can provide AI services for terminal devices or other network devices, for example, AI nodes, computing power nodes, AI-capable RAN nodes, AI-capable core network elements, etc. on the network side (access network or core network), and the network device can also be a cloud server or a virtual machine (VM).

[0156] In the embodiments of the present application, the device for implementing the function of the network device can be a network device or a device capable of supporting the network device to implement the function, such as a chip system, which can be arranged in the network device. In the technical solutions provided in the embodiments of the present application, the device for implementing the function of the network device is taken as an example to describe the technical solutions provided in the embodiments of the present application.

[0157] In the scenario shown in FIG. 1A and FIG. 1B, there are a transmitting end and a receiving end. The transmitting end can independently transmit a sensing signal for scanning without the receiving end. The receiving end can independently process a return signal without the transmitting end. The transmitting end and the receiving end can jointly scan, that is, the transmitting end transmits a beam in combination with the capability of the receiving end, and the receiving end processes a return signal in combination with the direction of the beam transmitted by the transmitting end. Through experimental comparison, it is found that the sensing quality of the sensing result obtained by joint scanning of the transmitting end and the receiving end is better than that obtained by independent scanning of the transmitting end or the receiving end. As shown in FIG. 2A, when the number of antenna elements of the transmitting end and the receiving end is 31 and the interval of the antenna elements is half of the carrier wavelength, the beams corresponding to the transmitting end, the receiving end and the joint of the two are respectively line 201, line 202 and line 203 in FIG. 2A. As can be seen from FIG. 2A, compared with the transmitting beam (line 201) and the receiving beam (line 202), the main lobe of the beam corresponding to the joint of the transmitting and receiving (line 203) is narrower and the side lobe is lower, that is, the resolution performance and the side lobe suppression performance of sensing are improved, such as peak to side lobe ratio (PSLR) and integrated side lobe ratio (ISLR).

[0158] The central node can assist in determining the scanning information of the transmitting beam of the transmitting end or the sensing node, and then the transmitting end or the sensing node generates a sensing signal according to the scanning information of the transmitting beam. The sensing signal can sense a corresponding region. The receiving end or the sensing node receives a return signal of the corresponding region, and then the receiving end or the sensing node can determine an imaging result according to the return signal and using a sensing algorithm. The imaging result can be in the form of a point cloud.

[0159] In this application, the point cloud forms of the imaging results obtained by using different sensing algorithms are different, and in the same sensing algorithm, the imaging results obtained by using transmitting beams determined at different scanning intervals are also different. As shown in FIG. 2B, it is a schematic diagram of the imaging results obtained by using a digital beam forming (DBF) algorithm to process return signals corresponding to transmitting beams determined at different scanning intervals. As shown in FIG. 2C, it is a schematic diagram of the imaging results obtained by using a compressive sensing (CS) algorithm to process return signals corresponding to transmitting beams determined at different scanning intervals.

[0160] The three images shown in FIG. 2B are imaging results obtained by the DBF algorithm when the scanning intervals of the transmit beams in the azimuth direction and the elevation direction are 15°, 1.5° and 0.5° respectively. The three images are obtained by scanning the same region and the same coordinate system is used. Therefore, from the comparison of the three images, it can be seen that the width of the main lobe of the beam circled by the circle decreases obviously, that is, the resolution is enhanced, when the scanning interval changes from [15°, 15°] to [1.5°, 1.5°]. It can be seen that, compared with the scanning interval [15°, 15°], the imaging result obtained by using the scanning interval [1.5°, 1.5°] has higher perception quality. When the scanning interval is further reduced from [1.5°, 1.5°] to [0.5°, 0.5°], from the comparison of the two images, it can be seen that the change of the imaging result is not obvious, but the scanning overhead in the azimuth direction and the elevation direction is increased by 3 times, and the overall scanning overhead is increased by 9 times. It can be seen that the scanning interval of the transmit beam directly affects the imaging quality and the scanning overhead.

[0161] The three images shown in FIG. 2C are imaging results obtained by the CS algorithm when the scanning intervals of the transmit beams in the azimuth direction and the elevation direction are 15°, 10° and 4° respectively. The three images are obtained by scanning the same region and the same coordinate system is used. Therefore, from the comparison of the three images, it can be seen that the width of the main lobe of the beam decreases obviously, that is, the resolution is enhanced, when the scanning interval changes from [15°, 15°] to [10°, 10°]. It can be seen that, compared with the scanning interval [15°, 15°], the imaging result obtained by using the scanning interval [10°, 10°] has higher perception quality. When the scanning interval is further reduced from [10°, 10°] to [4°, 4°], from the comparison of the two images, it can be seen that strong scattering points appear in the direction where there is no target when the scanning interval is 4°, that is, the perception result obtained by the CS algorithm is wrong, because when the scanning interval is too small, the underdetermined equation problem in the solving process of the CS algorithm becomes an overdetermined equation problem, and the CS result can be unstable. Therefore, when the CS algorithm is used, the scanning interval of the transmit beam directly affects the imaging quality and the accuracy of the imaging result.

[0162] As can be seen from the above introduction, although the transceiver joint scanning scene can obtain certain perception gain, if the scanning parameters are not selected properly, the scanning overhead will be reduced, or the target points in the imaging result will be wrong.

[0163] Based on the above reasons, the embodiment of the present application provides a perception method, which can obtain imaging results with higher perception quality at lower scanning cost. The perception method provided by the embodiment of the present application is described below.

[0164] As shown in FIG. 3, the perception method provided by the embodiment of the present application includes the following steps.

[0165] S301. The first communication device acquires scanning information of a transmission beam corresponding to a first region; wherein the scanning information of the transmission beam includes a parameter for indicating a scanning interval, or the scanning information of the transmission beam is determined through the scanning interval; wherein the scanning interval is determined through a first range, and the first range is determined through a first resolution, and the first resolution meets the resolution requirement of the imaging result of the first region.

[0166] The first communication device can be a perception node with a transceiver or a transmission end of a perception signal. The first communication device can be a network device, a terminal device, or a chip in the network device or a chip in the terminal device, and the implementation of the present application is not limited thereto.

[0167] In the present application, the scanning information of the transmission beam corresponding to the first region can be received by the first communication device from the second communication device, or can be determined by the first communication device. The first region can be a region selected by a user, a region selected by the first communication device or the second communication device. The second communication device can be a center node, which can be a transmission end of a perception signal, or a node configured with perception parameters for a reception end of a perception signal, and / or a node for aggregating perception results. The center node can be a network device or a chip in the network device, and of course, the center node can also be other forms of devices, such as a terminal device or a chip in the terminal device. The second communication device can also be a network element of a core network, such as a (sensing management function, SMF) network element or a location management function (location management function, LMF) network element. The second communication device can also be a reception end of an echo signal corresponding to a perception signal.

[0168] In the present application, the scanning information of the transmit beams can be used to generate a plurality of information of the transmit beams (first beams), each first beam scans a sub-region in the first region, and the sub-regions scanned by different first beams do not overlap. The plurality of information can include a scanning range in the azimuth direction, a scanning range in the elevation direction, a scanning interval, or a parameter for indicating the scanning interval, such as: if the minimum scanning granularity is agreed to be scanned, the scanning interval can be indicated by a multiple, and the product of the multiple and the minimum scanning granularity is the scanning interval of the sub-region. The scanning interval refers to the angle (or position) interval between two adjacent transmit beams, and the scanning intervals between different adjacent transmit beams can be the same or different. The plurality of information can also include the transmission time of each first beam.

[0169] In the present application, the first resolution can be selected by the user, and the first resolution meets the resolution requirement of the imaging result of the first region. In the perception scene, the meaning of resolution refers to the minimum interval, such as distance interval or angle interval, that can distinguish adjacent targets in the imaging result, which determines the imaging precision and target distinguishing ability. The resolution requirement refers to the resolution that meets the set minimum interval, such as: the minimum distance interval or the minimum angle interval that needs to be met.

[0170] S302. The first communication device transmits a first beam according to the scanning information of the transmit beams, and the first beam is used to scan the first region.

[0171] The echo signal generated by the first beam scanning the first region can be obtained after the receiving end processes the echo signal using a perception algorithm. The receiving end can be the first communication device or another communication device.

[0172] The scheme provided by the embodiments of the present application can obtain a better imaging result with high perception quality through the upper limit of the first range, and can effectively reduce the scanning overhead through the lower limit of the first range. Therefore, the scheme provided by the present application can determine the scanning information of the transmit beams by determining the scanning interval according to the first range to perform beam scanning, which can obtain an imaging result with high perception quality and effectively reduce the scanning overhead.

[0173] Optionally, the first resolution is not greater than the second resolution, and the second resolution is a resolution determined by the transmission capability of the transmitting end and the reception capability of the receiving end.

[0174] In the embodiments of the present application, the second resolution can be a theoretical value of the resolution determined according to the transmission capability of the transmitting end and the receiving capability of the receiving end. The first resolution is not greater than the second resolution, that is, the first resolution is less than or equal to the second resolution, so that the transmission capability of the transmitting end and the receiving capability of the receiving end can be utilized as much as possible, and the resource utilization rate of the transmitting end and the receiving end can be improved.

[0175] In some scenarios, S301 can be determined by the second communication device and then sent to the first communication device. In the following, the interaction process between the first communication device and the second communication device is introduced in different scenarios.

[0176] As shown in FIG. 4, taking a single-base sensing scenario in which the first communication device is a sensing node and the second communication device is a center node as an example, the sensing method provided in the embodiments of the present application includes the following steps.

[0177] S401. The first communication device sends a transceiving joint sensing imaging service request to the second communication device. Correspondingly, the second communication device receives the transceiving joint sensing imaging service request.

[0178] The transceiving joint sensing imaging service request is used to request the center node to assist the transceiving integrated sensing node to configure the scanning information of the transmission beam.

[0179] S402. The first communication device sends capability information to the second communication device. Correspondingly, the second communication device receives the capability information.
