Description

Technical Field

[0001] The present application relates to the field of communication and perception, and more specifically, to a method and device for integrating synaesthesia in the field of communication and perception. Background Art

[0002] With the emergence of emerging business scenarios such as autonomous driving and virtual reality, mobile communication systems such as the fifth generation mobile communication technology (5G) or the sixth generation mobile communication technology (6G) need to have both communication and perception capabilities. Perception technology and communication technology have certain similarities in terms of spectrum, waveform and antenna design, which has prompted the study of integrated sensing and communication (ISAC). ISAC refers to a new information processing technology that realizes the coordination of perception and communication functions based on software and hardware resource sharing or information sharing, which can effectively improve the system spectrum efficiency, save hardware space and reduce maintenance costs.

[0003] In the ISAC system, wireless resources must be able to sense and communicate. Therefore, how to manage and allocate wireless resources is a concern in the current ISAC system. Summary of the invention

[0004] The present application provides a method and device for integrating synaesthesia, which can improve resource utilization as much as possible, so as to maximize the use of wireless resources and thus improve system performance.

[0005] In a first aspect, a method for integrating synaesthesia is provided, which is applied to a first device, and the method includes: sending a measurement report obtained by the first device measuring a first link based on a multiplexing measurement condition to a first network device, the multiplexing measurement condition is used to determine a communication link that can be used for perception, the first link is a communication link currently used to transmit communication signals, and the measurement report includes multiplexing indication information, and the multiplexing indication information is used to indicate whether the first link can be used for perception; receiving first scheduling information sent by the first network device according to the measurement report, the first scheduling information is used to indicate a first resource, and the first resource includes at least one resource: a perception-only resource, a communication-only resource, and a communication perception resource.

[0006] In the method of synaesthesia integration provided in the embodiment of the present application, the first device as a measurement node measures the first link (i.e., the communication link) currently transmitting the communication signal based on the multiplexed measurement condition. The multiplexed measurement condition is used to determine the communication link that can be used for perception, so that the first network device can determine whether the first link can be used for perception based on the measurement report obtained by measuring the first link. Then, the first network device can comprehensively consider the scheduling of communication and perception resources based on whether the first link is used for perception, and indicate the resources (such as the first resource) scheduled for the first device through the scheduling information sent to the first device. The scheduled resources include only perception resources, only communication resources, and communication perception resources. At least one. In this way, when the scheduled resources include communication perception resources, the first device can communicate and perceive based on the same resource (communication perception resource) on the first link, that is, perceive based on the communication signal transmitted on the communication perception resource. In this way, since no additional perception resources are required, the occupancy of perception resources is reduced, and resource utilization can be effectively improved; when the scheduled resources include only perception resources or only communication resources, communication and perception can be kept normal as much as possible to reduce interference between communication and perception. Therefore, the embodiment of the present application measures the first link (i.e., the communication link) currently transmitting the communication signal based on the multiplexing measurement conditions to determine whether the communication resources of the first link can be used for the perception scheme, which can provide a multiplexing basis for the scheduling of communication and perception resources, and improve the resource utilization as much as possible while maintaining the normal communication and perception as much as possible, so as to maximize the use of wireless resources and thus improve system performance.

[0007] In some embodiments, the multiplexing measurement conditions include a first type of conditions, and the first type of conditions are used to determine a communication link that can provide perception information.

[0008] In the above embodiment, determining the communication link that can provide perception information through the first type of conditions means that the first device can obtain information (perception information) related to the perception target or perception area. In this way, the communication link that can provide perception information is possible for perception, which ensures the feasibility of measuring whether the communication link can be used for perception as much as possible.

[0009] In some embodiments, the first category of conditions includes at least one of the following conditions:

[0010] The first condition: the communication node on the communication link has an association relationship with the sensing target;

[0011] The second condition: the communication beam on the communication link can be used for sensing;

[0012] The third condition: the scatterer on the communication link is within the sensing area;

[0013] Fourth condition: the distance between the communication node on the communication link and the center position of the perception area is less than the first threshold, or the distance between the communication node on the communication link and the perception target is less than the second threshold.

[0014] In some embodiments, the multiplexing measurement conditions further include a second type of conditions, where the second type of conditions are related to communication signals.

[0015] In the above embodiment, the second type of condition focuses on the characteristics of the communication channel of the communication link, and more on the channel conditions of the communication channel. If the currently measured first link (communication link) can provide perception information, but the channel conditions of the communication channel of the first link are not ideal, resulting in poor performance of the received communication signal, it also means that the performance of perception based on the communication signal of the first link is not good, which affects the effect of perception. Therefore, in combination with the first type of condition, the communication link is measured through the second type of condition, so that the channel conditions of the communication channel can be evaluated based on the communication signal, and the communication link with ideal channel conditions and capable of providing perception information can be selected, thereby improving the effect of perception when the link (or resource) is reused.

[0016] In some embodiments, the second category of conditions includes at least one of the following conditions:

[0017] Fifth condition: the signal quality of the communication signal received on the communication link is greater than or equal to the signal quality threshold;

[0018] Sixth condition: the maximum Doppler frequency shift of the communication signal received on the communication link is less than or equal to the Doppler frequency shift threshold;

[0019] Seventh condition: when the communication link is a multipath link, the power of each sublink in at least one sublink of the communication link is greater than or equal to the power threshold, or the power ratio of the power of each sublink in at least one sublink of the communication link to the power of the communication link is greater than or equal to the power ratio threshold;

[0020] The eighth condition is that when the communication link is a multipath link, the signal quality of the communication signal received on each sub-link in at least one sub-link of the communication link is greater than or equal to the signal quality threshold;

[0021] The ninth condition is that when the communication link is a multipath link, the maximum Doppler frequency shift of the communication signal received on each sub-link in at least one sub-link of the communication link is less than or equal to the Doppler frequency shift threshold.

[0022] In the above-mentioned step of sending a measurement report obtained by the first device measuring the first link based on the multiplexing measurement condition to the first network device, when the first link meets the first type of conditions and the second type of conditions, the measurement report is sent to the first network device, wherein the multiplexing indication information is used to indicate that the first link can be used for perception; or, when the first link meets the first type of conditions and does not meet the second type of conditions, the measurement report is sent to the first network device, wherein the multiplexing indication information is used to indicate that the first link is not available for perception.

[0023] In some embodiments, when the first link does not satisfy the first type of condition, the measurement report is not sent to the first network device.

[0024] In the above embodiment, when the first link does not meet the first type of conditions, the first device does not send a measurement report to the first network device. When the first network device does not receive the measurement report, it can be determined that the first link does not meet the first condition. Compared with the method of sending signaling, the signaling overhead can be effectively saved.

[0025] In some embodiments, the multiplexing indication information is used to indicate that the first link can be used for sensing; and the measurement report further includes sensing assistance information, and the sensing assistance information includes at least one of the following:

[0029] second signal information, where the first link is a multipath link, the second signal information is used to indicate the signal quality of a communication signal received on a sub-link that meets a multiplexing measurement condition in the first link;

[0030] Power information: when the first link is a multipath link, the power information is used to indicate the power ratio of the power of the sub-link that meets the multiplexing measurement condition in the first link to the power of the first link;

[0031] The second Doppler frequency shift information, when the first link is a multipath link, the second Doppler frequency shift information is used to indicate the maximum Doppler frequency shift of the communication signal received on the sub-link that meets the multiplexing measurement condition in the first link.

[0032] In the above embodiment, when the multiplexing indication information is used to indicate that the first link can be used for perception, the measurement report sent by the first device also includes perception auxiliary information, which enables the first network device to determine whether the first link meets the perception requirements in combination with the perception measurement information, so as to ultimately determine whether the first link is perceptible, which is equivalent to increasing the measurement requirements for the communication link, and can ultimately determine the communication link with good perception effect, thereby improving the perception performance when the link (or resource) is multiplexed for perception.

[0043] In the above embodiment, the function of the first resource scheduled by the scheduling information is indicated by using the RNTI of the DCI carrying the scheduling information. Since no additional information or field is needed, the signaling overhead can be reduced.

[0044] In some embodiments, the first scheduling information also includes priority information; and, when at least part of the first resources overlap with other resources in the time domain and frequency domain, the priority information is used to indicate that at least part of the resources preferentially carry communication signals or preferentially carry perception signals, wherein the first resource is a perception resource and the other resources are communication resources, or the first resource is a communication resource and the other resources are perception resources.

[0136] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0137] With the emergence of emerging business scenarios such as autonomous driving and virtual reality, future mobile communication systems (such as post-5G or 6G) need to have both communication and perception capabilities. Perception technology and communication technology have certain similarities in terms of spectrum, waveform, and antenna design, which has prompted the study of integrated sensing and communication (ISAC). ISAC refers to a new information processing technology that realizes the coordination of perception and communication functions based on software and hardware resource sharing or information sharing, which can effectively improve the system spectrum efficiency, save hardware space, and reduce maintenance costs.

[0138] In the ISAC system, wireless resources are used for both communication and perception. How to manage and allocate wireless resources is a concern in the current ISAC system. In related technologies, different resources are allocated for perception and communication to achieve their respective functions, that is, the allocated perception resources are only used for perception, and the allocated communication resources are only used for communication. However, with the increasing number of services and users, the two services of communication and perception are bound to cause competition for resources, thereby reducing system performance.

[0139] Therefore, in order to maximize the utilization of wireless resources to improve system performance, an embodiment of the present application provides a method of integrating interawareness, which measures the communication link (such as the first link) that currently transmits the communication signal based on the multiplexing measurement condition, wherein the multiplexing measurement condition is used to determine the communication link that can be used for perception, so that the network device can determine whether the communication resources of the communication link are used for perception (or whether the communication resources are reused) based on the measurement report obtained by measuring the link. Furthermore, the network device can comprehensively consider the scheduling of communication and perception resources based on whether the communication resources of the communication link are used for perception, and indicate the scheduled resources (such as the first resource) through scheduling information. The scheduled resources include at least one of perception-only resources, communication-only resources, and communication perception resources, wherein the communication perception resources are used for communication and perception, and can be perceived based on the communication signals transmitted on the communication perception resources. In this way, when the scheduled resources include communication perception resources, since perception can be performed based on the communication signals transmitted on the communication perception resources, no additional perception resources are required, and the occupancy of the perception resources is reduced. Therefore, the resource utilization rate can be effectively improved; when the scheduled resources include only perception resources or only communication resources, the normal communication and perception can be maintained as much as possible, and the interference between communication and perception can be reduced. Therefore, the scheme of measuring the communication link based on the reuse measurement conditions in the embodiment of the present application to determine whether the communication resources of the communication link are used for perception can provide a reuse basis for the scheduling of communication and perception resources, and improve the resource utilization rate as much as possible while maintaining the normal communication and perception as much as possible, so as to maximize the use of wireless resources and improve system performance.

[0140] It should be understood that the communication perception resources described in the embodiments of the present application are used for perception and communication, which means that the signals transmitted on the communication perception resources can be used for both communication and perception, that is, the signals transmitted on the communication perception resources have two functions, one is to realize the communication function, and the other is to realize the perception function. When perception is performed based on the communication perception resources, specifically, perception is performed based on the communication signal transmitted on the communication perception resources.

[0141] Below, relevant terms of the embodiments of the present application are first introduced.

[0142] 1. Communication nodes and communication links

[0143] Communication nodes usually have the ability to receive and process communication signals, such as network devices or terminal devices.

[0144] A communication link refers to a link used to carry communication signals. In some scenarios, a communication link is a link between two communication nodes for communication. For example, a communication link is a link between a network device and a terminal device for carrying communication signals. Figure 1 The communication link shown in (b) of FIG. 1 may be a downlink communication link A1 or an uplink communication link A2. In other scenarios, a communication node sends a communication signal to another communication node. There is a scatterer on the communication link between the two communication nodes. The communication signal is reflected or scattered by the scatterer. The reflected or scattered communication signal reaches the communication node that sent the communication signal. In this scenario, the communication link includes a link where the communication signal sent by the communication node reaches the scatterer from the communication node and a link where the communication signal reaches the communication node from the scatterer after being reflected or scattered by the scatterer, such as Figure 7 and Figure 8 The communication link shown may be a communication link formed by a communication link A11 and a communication link A13.

[0145] It should be understood that the communication signal in the embodiment of the present application represents any signal transmitted on the communication resource, which can be a signal with specific meaning that carries data or information, or a reference signal, and the present application does not impose any limitation thereto.

[0146] 2. Perception nodes, perception targets, and perception links

[0147] In the ISAC system, for perception services, perception is performed by analyzing the direct, reflected or scattered signals of the perception signals, and the characteristics of the received signals are used to perceive the environment to complete functions such as positioning, ranging, speed measurement, imaging, detection, identification, and environmental reconstruction, thereby realizing the perception and exploration of the physical world.

[0148] In the ISAC system, the nodes involved in the sending, receiving and processing of the perception signal include at least the perception node and the perception target. The processing of the perception signal includes various processing before sending the perception signal, such as physical layer or RF processing such as coding modulation, power control, antenna control, etc. before the perception signal is sent. The processing of the perception signal also includes various processing after receiving the perception signal, such as physical layer or RF processing such as decoding and demodulation, interference elimination, etc. after receiving the perception signal. For the reception of the perception signal, the perception node can receive both the signal directly radiated by the perception signal (i.e., the perception signal) and the signal reflected or scattered by the perception signal (also referred to as the echo signal). Therefore, in an embodiment of the present application, a node or device described below receives a perception signal, which can be a signal directly radiated by the perception signal (i.e., the perception signal) or a signal reflected or scattered by the perception signal (echo signal).

[0149] A sensing node usually has the ability to send, receive and process sensing signals, such as a network device or a terminal device.

[0150] The sensing target can be an active sensing target or a passive sensing target.

[0151] Active sensing targets have the ability to send, receive and process sensing signals. The sensing signals sent by active sensing targets are received and processed, thereby realizing the functions of positioning, detecting, tracking and identifying the sensing targets. Common active sensing targets may include devices such as mobile phones, vehicles, and IoT devices. In the ISAC system, the signals emitted by these active targets can be used for integrated processing of communication and perception to improve spectrum utilization and overall system performance. For example, in an intelligent transportation system, vehicles are active sensing targets, and the GPS signals and communication signals they emit can be received by roadside ISAC base stations to realize functions such as vehicle positioning, traffic flow monitoring, and road condition analysis.

[0152] Passive sensing targets usually do not have the ability to send, receive, and process sensing signals. The simplest passive sensing targets may only be able to reflect or scatter electromagnetic waves. Passive sensing targets can include a wide range of physical environments such as buildings, urban facilities (such as billboards, bridges, etc.), and traffic conditions (such as pedestrians, bicycles). By receiving and processing the electromagnetic wave signals reflected or scattered by these passive targets, the ISAC system can achieve comprehensive perception and reconstruction of the surrounding environment. For example, in a smart city, the ISAC system can use the signals reflected or scattered by passive sensing targets such as buildings and bridges to perform 3D imaging and virtual reconstruction of the urban environment, providing strong support for urban planning and management. For another example, the positioning and tracking of aircraft or satellites can be achieved by detecting the signals of sunlight reflected from them.

[0153] At present, there are two main sensing modes known in the industry: the sensing mode of A sending and B receiving and the sensing mode of spontaneous transmission and self-reception. In the sensing mode of A sending and B receiving, the sensing node that sends the sensing signal is different from the sensing node that receives the sensing signal. In the sensing mode of spontaneous transmission and self-reception, the sensing node that sends the sensing signal and the sensing node that receives the echo signal of the sensing signal are the same sensing node.

[0154] 3. Communication resources, communication resources only, perception resources, perception resources only, communication perception resources

[0155] Communication perception resources refer to resources used for communication and perception. Signals transmitted on communication perception resources can be used for both communication and perception, that is, signals transmitted on communication perception resources have two functions, one is to realize the communication function, and the other is to realize the perception function. When perception is performed based on communication perception resources, specifically, perception is performed based on communication signals transmitted on communication perception resources. It should be understood that the communication signals transmitted on communication perception resources can be signals with specific meanings that carry data or information, or can be reference signals. Communication perception resources include, but are not limited to, time domain resources, frequency domain resources, and spatial domain resources.

[0156] Communication resources refer to resources used for communication, and communication is performed through communication signals carried on the communication resources. Communication resources include but are not limited to time domain resources, frequency domain resources, and spatial domain resources. Among them, the spatial domain resources of communication resources may include communication beams.

[0157] Communication-only resources refer to resources used only for communication.

[0158] For communication resources, if part of the communication resources can also be used for perception, then the communication resources may include communication-only resources and communication perception resources.

[0159] The sensing resources refer to the resources used for sensing, which are sensed by sensing signals carried on the sensing resources. The sensing resources include but are not limited to time domain resources, frequency domain resources, and spatial domain resources. Among them, the spatial domain resources of the sensing resources may include sensing beams.

[0160] Perception-only resources refer to resources that are used only for perception.

[0161] For sensing resources, if part of the sensing resources can also be used for communication, then the sensing resources include sensing-only resources and communication sensing resources.

[0162] In order to facilitate understanding of the embodiments of the present application, Figures 1 to 8 , give a brief introduction to the perception scenarios and communication scenarios in the ISAC system.

[0163] Figures 1 to 8 It is a schematic diagram of the perception scenario and communication scenario of the ISAC system provided in the embodiment of the present application.

[0164] Among them, Figures 1 to 3 In the sensing scenario shown, the sensing mode is A sends and B receives, the sensing target is a passive sensing target, one sensing node sends a sensing signal, the sensing target reflects or scatters the sensing signal, and the other sensing node receives the signal reflected or scattered by the sensing target. Figures 1 to 3 In the communication scenario shown, the communication link is a link between two communication nodes. On the communication link, a communication signal sent by one communication node reaches another communication node after being reflected or scattered by a scatterer.

[0165] exist Figure 1 In the perception scenario shown in Figure (a), network device A and terminal device A act as perception nodes. In perception link B1, network device A sends a perception signal, and terminal device A receives the signal after the perception signal is reflected or scattered, and performs perception based on the received signal. In perception link B2, terminal device A sends a perception signal, and network device A receives the signal after the perception signal is reflected or scattered, and performs perception based on the received signal.

[0166] exist Figure 1 In the communication scenario shown in Figure (b), network device A and terminal device A serve as communication nodes. In communication link A1, network device A sends a communication signal, which is reflected or scattered by a scatterer, and terminal device A receives the signal after the communication signal is reflected or scattered. In communication link A2, terminal device A sends a communication signal, which is reflected or scattered by a scatterer, and network device A receives the signal after the communication signal is reflected or scattered.

[0167] Figure 2 The perception and communication scenarios shown are similar to Figure 1 The perception scenario shown is similar to the communication scenario, and the difference between the two lies in the difference between the perception nodes and the communication nodes. Figure 2 In Figure (a), the sensing nodes in the sensing scene are network devices A and B. Figure 2 In Figure (b), the communication nodes in the communication scenario are also network device A and network device B.

[0168] exist Figure 3 The perception and communication scenarios shown are similar to Figure 1 The perception scenario shown is similar to the communication scenario, and the difference between the two lies in the difference between the perception nodes and the communication nodes. Figure 3 In Figure (a), the sensing nodes in the sensing scene are terminal device A and terminal device B. Figure 3In Figure (b), the communication nodes in the communication scenario are also terminal device A and terminal device B.

[0169] In addition, terminal device A also interacts with network device A, and network device A schedules relevant resources (such as scheduling information) or transmits relevant information (such as measurement indication information below) or transmits relevant data for terminal device A. Terminal device B also interacts with network device B, and network device B schedules relevant resources (such as scheduling information) or transmits relevant information (such as measurement indication information below) or transmits relevant data for terminal device B. In one example, network device A and network device B are the same device, and in another example, network device A and network device B are different devices.

[0170] exist Figures 1 to 3 In the ,awareness link is the link between two sensing nodes, and the ,communication link is the link between two communication nodes.

[0171] exist Figures 1 to 3 In the communication scenario shown, when the scatterer in the communication link (such as communication link A1 or communication link A2) is a perception target, the perception target can also serve as a scatterer of the communication link, and the communication link can provide perception information. At this time, the perception target can be used as a scatterer shared by the perception link and the communication link (referred to as a shared scatterer). In this way, if the communication link meets some conditions for perception (such as multiplexing measurement conditions), it means that the communication resources of the communication link can also be used for perception. Therefore, it is possible to consider multiplexing the communication resources of the communication link, or in other words, use the communication resources of the communication link as communication perception resources, and perceive through the communication signals transmitted on the communication resources of the communication link to improve resource utilization. The specific process can be referred to the relevant description below, which will not be repeated.

[0172] exist Figures 4 to 6 In the sensing scenario shown, the sensing mode is a sensing mode where A sends and B receives, the sensing target is an active sensing target, and the sensing target is any sensing node, one sensing node sends a sensing signal, and the other sensing node receives the sensing signal. Figures 4 to 6 In the communication scenario shown, a communication link is a link between two communication nodes, on which one communication node sends a communication signal and the other communication node receives the communication signal.

[0173] exist Figure 4In the perception scenario shown in Figure (a), network device A and terminal device A act as perception nodes. In perception link B1, network device A sends a perception signal, terminal device A receives the signal after the perception signal is directly projected, and performs perception based on the received signal. The perception target can be network device A or terminal device A, which is based on the actual situation and is not limited in any way by the embodiments of the present application. In perception link B2, terminal device A sends a perception signal, network device A receives the signal after the perception signal is directly projected, and performs perception based on the received signal. The perception target can be network device A or terminal device A, which is based on the actual situation. In the case where the perception target in perception link B2 is network device A, network device A can be located by the perception signal received by network device A. For example, for future mobile network devices (such as aerial base stations), mobile network devices can be used as hotspots to cover and supplement some areas. Therefore, it is necessary to locate such mobile network devices.

[0174] exist Figure 4 In the communication scenario shown in Figure (b), network device A and terminal device A act as communication nodes. In communication link A1, network device A sends a communication signal, and terminal device A receives a signal directly transmitted by the communication signal. In communication link A2, terminal device A sends a communication signal, and network device A receives a signal directly transmitted by the communication signal.

[0175] Figure 5 The perception and communication scenarios shown are similar to Figure 4 The perception scenario shown is similar to the communication scenario, the difference between the two lies in the difference between the perception node and the communication node. Figure 5 In Figure (a), the sensing nodes in the sensing scene are network devices A and B. Figure 5 In Figure (b), the communication nodes in the communication scenario are also network device A and network device B.

[0176] Figure 6 The perception and communication scenarios shown are similar to Figure 4 The perception scenario shown is similar to the communication scenario, the difference between the two lies in the difference between the perception node and the communication node. Figure 6 In Figure (a), the sensing nodes in the sensing scene are terminal device A and terminal device B. Figure 6 In Figure (b), the communication nodes in the communication scenario are also terminal device A and terminal device B.

[0177] In addition, terminal device A also interacts with network device A, and network device A schedules relevant resources (such as scheduling information) or transmits relevant information (such as measurement indication information below) or transmits relevant data for terminal device A. Terminal device B also interacts with network device B, and network device B schedules relevant resources (such as scheduling information) or transmits relevant information (such as measurement indication information below) or transmits relevant data for terminal device B. In one example, network device A and network device B are the same device, and in another example, network device A and network device B are different devices.

[0178] exist Figure 4 As shown in FIG6 , a sensing link is a link between two sensing nodes, and a communication link is a link between two communication nodes.

[0179] exist Figure 4 In the communication scenario shown in FIG6 , when the sensing target is a communication node (network device or terminal device), if the communication link (such as communication link A1 or communication link A2) satisfies some conditions for sensing (such as multiplexing measurement conditions), it means that the communication resources of the communication link can also be used for sensing. Therefore, it is possible to consider multiplexing the communication resources of the communication link, or in other words, use the communication resources of the communication link as communication sensing resources, and sense through the communication signals transmitted on the communication resources of the communication link to improve resource utilization. The specific process can be referred to the relevant description below, which will not be repeated here.

[0180] exist Figure 7 and Figure 8 In the sensing scenario shown, the sensing mode is a self-transmitting and self-receiving sensing mode, the sensing target is a passive sensing target, and the same sensing node sends a sensing signal and receives a signal reflected or scattered by the sensing target. Figure 7 and Figure 8 In the communication scenario shown, in the first case, the communication link is a link between two communication nodes, on which one communication node sends a communication signal and the other communication node receives the communication signal. In addition, in the second case, a communication node sends a communication signal, and after the communication signal is reflected or scattered by a scatterer, the communication node that sends the communication signal also receives the reflected or scattered communication signal. In this case, the communication link may include a link from the communication node to the scatterer for the communication signal sent by the communication node and a link from the scatterer to the communication node for the communication signal after being reflected or scattered by the scatterer. It should be understood that in the communication scenario, the communication link in the second case is generated in the process of sending and receiving communication signals between two communication nodes. Although the communication link in the second case carries a communication signal, in general, the communication node does not use the communication signal received from the communication link for communication, or in other words, the communication node ignores the communication signal received from the communication link.

[0181] exist Figure 7 In the perception scenario shown, network device A acts as a perception node. The perception signal sent by network device A is reflected or scattered by the perception target through perception link B11, and then reaches network device A through perception link B12. Network device A receives the reflected or scattered perception signal carried on perception link B12. In this scenario, the perception link formed by perception link B11 and perception link B12 is used for perception in a self-transmitting and self-receiving perception mode.

[0182] exist Figure 7 In the communication scenario shown, network device A can be used as a communication node, and terminal device A is another communication node. Network device A sends a communication signal to terminal device A, and the communication signal is transmitted to the terminal device through communication link A11 and communication link A12. The communication link formed by communication link A11 and communication link A12 is similar to Figure 1 The communication link between the two communication nodes shown. In addition, the communication signal on the communication link A11 is reflected or scattered by the scatterer and then returned to the network device A through the communication link A13. Therefore, the communication link formed by the communication link A11 and the communication link A13 can also be called a communication link, that is, the communication link includes the communication link A11 and the communication link A13. The communication link A11 is the link for the communication signal sent by the network device A to reach the scatterer from the network device A, and the communication link A13 is the link for the communication signal after being reflected or scattered by the scatterer to reach the network device A from the scatterer. It should be noted that although the communication link formed by the communication link A11 and the communication link A13 carries the communication signal, the network device A does not use the communication signal received from the communication link for communication.

[0183] Figure 8 The perception and communication scenarios shown are similar to Figure 7 The perception scenario shown is similar to the communication scenario, the difference between the two lies in the difference between the perception node and the communication node. Figure 8 In the above, the sensing node in the sensing scenario is terminal device A, and the communication node in the communication scenario is also terminal device A. In addition, terminal device A also interacts with network device A, and network device A schedules relevant resources (such as scheduling information) or transmits relevant information (such as the measurement indication information below) or transmits relevant data for terminal device A.

[0184] exist Figure 7 and Figure 8 In the communication scenario shown, when Figure 7 and Figure 8When a scatterer on the communication link shown (such as the communication link formed by the communication link A11 and the communication link A13) is a sensing target, if the communication link satisfies some conditions for sensing (such as multiplexing measurement conditions), it means that the communication resources of the communication link can also be used for sensing. Therefore, it is possible to consider multiplexing the communication resources of the communication link, or in other words, use the communication resources of the communication link as communication sensing resources, and sense through the communication signals transmitted on the communication resources of the communication link to improve resource utilization. The specific process can be referred to the relevant description below, which will not be repeated.

[0204] Please refer to Figure 8, link 1 is a link between terminal device A (an example of the first terminal device) and the scatterer, link 1 includes communication link A11 and communication link A13, terminal device A is a communication node for sending and receiving communication signals, and terminal device A serves as a measurement node for link measurement. Network device A interacting with terminal device A comprehensively considers the allocation of communication resources and perception resources based on the measurement of link 1. Figure 8 In an example, the scatterer on link 1 is the sensing target.

[0205] In method 100, the first device acts as a measurement node for link measurement, and the first device obtains measurement indication information to perform link measurement based on the measurement indication information.

[0206] In some embodiments, in step S110, the first network device sends measurement indication information to the first device. Correspondingly, the first device receives the measurement indication information.

[0207] In some other embodiments (not shown in the figure), other devices (such as core network elements) send measurement indication information to the first device, and correspondingly, the first device receives the measurement indication information sent by the other devices.

[0208] In step S120 , the first device measures link 1 .

[0209] In this step, the first device measures link 1 based on the measurement indication information and obtains a measurement report.

[0210] As mentioned above, link 1 is a communication link currently used to transmit communication signals. The interpretation of link 1 is different in different scenarios, and reference may be made to the relevant description above.

[0211] In some embodiments, the measurement indication information includes condition information, the condition information is used to indicate a multiplexing measurement condition, and the multiplexing measurement condition is used to determine a communication link that can be used for sensing. After receiving the measurement indication information, the first device measures link 1 (communication link) used for transmitting communication signals based on the multiplexing measurement condition indicated by the condition information to determine whether link 1 can be used for sensing.

[0212] It should be understood that the multiplexing measurement conditions may include conditions of any content as long as the perceptible communication link can be determined. The embodiments of the present application do not impose any limitation thereto. The multiplexing measurement conditions are described in detail below and will not be described here in detail.

[0213] In the above scenarios 1 and 2, in other embodiments, the measurement indication information may include not only condition information but also measurement assistance information to assist the first device in performing link measurement, wherein the measurement assistance information includes at least one of the following information.

[0214] The location information of the first network device is used to indicate the location of the first network device.

[0215] Information about the transmitted communication beam on link 1 (referred to as the second communication beam), the transmitted communication beam on link 1 and the second communication beam can be described interchangeably, and the transmitted communication beam on link 1 (the second communication beam) represents the communication beam that transmits the communication signal on link 1. Exemplarily, the information about the transmitted communication beam on link 1 may include a beam identifier (such as a beam ID), a beam width, and a beam pointing. The beam pointing includes an azimuth angle and a pitch angle, and the beam width includes a horizontal beam width and a vertical beam width.

[0216] The information of the perceived target includes location information indicating the location of the perceived target. Exemplarily, the information of the perceived target may also include information indicating attributes of the perceived target (such as a person, a building, a vehicle, an urban facility, etc.), which is not limited here.

[0217] The information of the perception area includes location information for indicating the location of the perception area. Exemplarily, the information of the perception area may also include information of other parameters for indicating the perception area, which is not limited here.

[0218] Information about a first sensing beam, where the first sensing beam is a sensing beam for sending a sensing signal by the first network device. Exemplarily, the information about the first sensing beam may include a beam identifier (such as a beam ID), a beam width, and a beam direction.

[0219] The above measurement auxiliary information can be used in combination with different conditions of the multiplexed measurement conditions. For specific descriptions, please refer to the relevant descriptions of the process of performing link measurement based on various conditions below, which will not be repeated here.

[0220] The following further describes the multiplexing measurement condition and the process of performing link measurement based on the multiplexing measurement condition.

[0221] In some embodiments, the multiplexing measurement conditions include a first type of conditions for determining a communication link capable of providing the sensing information.

[0222] It should be understood that the communication link capable of providing perception information described herein means that the first device as a measuring node can obtain perception information related to the perception target or perception area after processing the communication signal received on the communication link. The perception information may include any content related to the perception target or perception area, for example, the perception information may include information indicating the location of the perception target or perception area, the moving speed of the perception target, and / or the moving trajectory of the perception target.

[0223] It should also be understood that if the link 1 (communication link) currently measured by the first device meets the first type of condition, it means that the link 1 can provide perception information. If the currently measured link 1 does not meet the first type of condition, it means that the link 1 cannot provide perception information, that is, the first device cannot obtain perception information after processing the communication signal received on the link 1.

[0224] It can be seen that the first type of condition focuses on whether the spatial resources of the communication link can be used for perception, that is, whether the airspace resources of the communication link can be used for perception. If the airspace resources of the communication link can be used for perception, then the communication link can provide perception information.

[0225] Exemplarily, the first type of conditions may include one or more conditions to jointly determine a communication link that can provide the sensing information. For a detailed description of each condition of the first type of conditions, please refer to the relevant description below, which will not be repeated here.

[0226] In some other embodiments, the multiplexing measurement conditions include not only the first type of conditions but also the second type of conditions, where the second type of conditions are related to the communication signal.

[0227] Among them, the second type of conditions is related to parameters such as signal quality of the communication signal and Doppler frequency shift used to evaluate the characteristics of the communication channel. For a detailed description, please refer to the relevant description below, which will not be repeated here. It can be seen that the second type of conditions focuses on whether the communication channel of the communication link can be used for sensing.

[0228] It should be noted that the first and second conditions have different focuses. The first condition focuses on whether the communication link can provide perception information, and pays more attention to whether the resources of the communication link in the airspace can be used for perception. The second condition focuses on the characteristics of the communication channel of the communication link, and pays more attention to the channel conditions of the communication channel. It can be understood that the currently measured link 1 (communication link) can provide perception information, which means that airspace resources can be used for perception. However, if the channel conditions of the communication channel of link 1 are not ideal, the performance of the received communication signal is not good, which means that the performance of perception based on the communication signal of link 1 is not good, which affects the effect of perception. In this case, it is not recommended to use link 1 for perception.

[0229] In an embodiment where the multiplexed measurement condition includes the first type of condition and the second type of condition, in step S120 where the first device measures link 1, in one example, the first device can measure link 1 in parallel based on the first type of condition and the second type of condition. In another example, link 1 can be measured in the order of the first type of condition and the second type of condition, for example, the first device first measures link 1 based on the first type of condition, and then measures link 1 based on the second type of condition. The specific process of the measurement is not limited here, and is determined specifically according to the latency requirements and computing power and other performance.

[0230] The following describes the first type of conditions and the second type of conditions in detail, and also illustrates a method for performing link measurement on the first device in combination with the first type of conditions and the second type of conditions.

[0231] The first type of conditions

[0232] Regarding the first type of conditions, in some embodiments, the first type of conditions includes at least one condition: a first condition, a second condition, a third condition, and a fourth condition.

[0233] The first condition is that the communication node on the communication link has an association relationship with the perception target.

[0234] It should be understood that if a communication node on a communication link has an association relationship with a perception target, it means that the communication link has the potential to provide perception information.

[0235] For the first device (communication node of link 1) on link 1 (communication link), the first device needs to determine whether it has an association relationship with the perception target. If the first device has an association relationship with the perception target, then link 1 meets the first condition, which means that link 1 has the potential to provide perception information.

[0236] There are two types of association relationships between a communication node and a sensing target: a first type of association relationship and a second type of association relationship.

[0237] In the first type of association, the communication node is the sensing target.

[0238] In one example, in Figure 4 In the communication scenario shown in Figure (b), network device A (an example of the first network device) and terminal device A (an example of the first device) are communication nodes of communication link A1 (an example of link 1). If terminal device A is a perception target, terminal device A as a measurement node can determine that it is a perception target.

[0239] In the second association relationship, the communication node is not the sensing target, but the communication node is related to the sensing target.

[0240] It can be understood that the communication nodes on the communication link are correlated with the perception target, so that the communication link can provide perception information.

[0241] In the second association relationship, exemplarily, the correlation between the communication node and the perception target can be determined by the information of the communication node and the information of the perception target, wherein the information of the communication node may include information indicating the position, moving speed, and / or moving track of the communication node, and the information of the perception target may include information indicating the position, moving speed, and / or moving track of the perception target. Exemplarily, the perception target may be a passive perception target.

[0242] Fig.10 It is another schematic diagram of the communication scenario provided in an embodiment of the present application.

[0243] In one example, reference Fig.10 In the figure (a), network device A (an example of the first network device) interacts with terminal device A (an example of the first device). Terminal device A is a communication node and a measurement node. The sensing target is the person Xiao Li, who carries terminal device A. In this case, terminal device A is bound to the sensing target, so the sensing target and the communication node have a strong correlation. In implementation, the information of terminal device A (an example of the first device) can be compared with the information of the sensing target (Xiao Li). If the correlation value of the position, moving speed, and moving trajectory indicated by the information of the two is greater than the threshold, it means that there is a strong correlation between the two. It can be understood that in this scenario, terminal device A can obtain sensing information (such as information of the sensing target) based on the signal sent by network device A. For example, since terminal device A is bound to the sensing target, terminal device A can determine the information such as the position, moving speed, and moving trajectory of the sensing target bound to terminal device A based on the information such as the position, moving speed, and moving trajectory determined by the signal sent by network device A, so as to obtain the information of the sensing target.

[0244] In another example, reference Fig.10In the figure (b), network device A (an example of the first network device) interacts with terminal device A (an example of the first device), and terminal device A interacts with terminal device B. Terminal device A is a communication node and also a measurement node. The perceived target is the person Xiao Li, who carries terminal device B. In this case, terminal device B is bound to the perceived target (Xiao Li). Due to the interaction between terminal device A and terminal device B, terminal device A has a strong correlation with the perceived target. In implementation, the information of terminal device B can be compared with the information of the perceived target (Xiao Li). If the correlation value of the position, moving speed, and moving trajectory indicated by the information of the two is greater than the threshold, it means that terminal device B has a strong correlation with the perceived target, and thus, terminal device A, which interacts with terminal device B, also has a strong correlation with the perceived target. It can be understood that in this scenario, terminal device A is able to obtain perception information (such as information of the perceived target) based on the signal sent by terminal device B.

[0245] The second condition is that the communication beam on the communication link can be used for sensing.

[0246] It should be understood that if the communication beam of a communication link can be used for sensing, it means that the communication link has the potential to provide sensing information.

[0247] For the currently measured link 1 (communication link), it can be determined whether the communication beam on link 1 can be used for perception. If the communication beam on link 1 can be used for perception, it means that link 1 has the potential to provide perception information.

[0248] The communication beam on the communication link described in the embodiment of the present application includes a receiving communication beam and a transmitting communication beam. The transmitting communication beam represents a communication beam for sending communication signals, and the receiving communication beam represents a communication beam for receiving communication signals. When both the transmitting communication beam and the receiving communication beam of the communication link meet the second condition, it means that link 1 has the potential to provide perception information.

[0249] For a receive communication beam on link 1 (communication link), the first device determines whether the receive communication beam on link 1 is available for sensing.

[0250] For the transmitted communication beam on link 1 (communication link), in one example, the communication node that transmits the communication signal (such as the first network device in the above-mentioned scenarios 1 and 2, the second terminal device in scenario 3, and the first terminal device in scenario 4) can determine whether the transmitted communication beam on link 1 is available for perception. In this way, the communication node that transmits the communication signal sends the communication signal to the first device on link 1 when determining that the transmitted communication beam of link 1 is perceptible. In this way, the first device only needs to determine whether the received communication beam of link 1 is available for perception. When it is determined that the received communication beam is available for perception, it means that the communication beam of link 1 meets the second condition.

[0251] In another example, the first device may also determine whether the transmitted communication beam on link 1 can be used for sensing based on the information used for sensing and the relevant information of the communication node that sends the communication signal (such as network device A in scenarios 1 and 2, or terminal device A in scenario 3). In this way, when both the transmitted communication beam and the received communication beam of link 1 meet the second condition, it means that the communication beam of link 1 meets the second condition. For example, the information used for sensing may include: information of the sensing target, information of the sensing area, and / or information of the transmitted sensing beam, and the relevant information of the communication node that sends the communication signal may include information of the transmitted communication beam on link 1 (such as the second communication beam above), and location information of the communication node that sends the communication signal. For the above scenarios 1 and 2, the first network device, as a communication node that sends the communication signal, may send information of the sensing target, information of the sensing area, and information of the first sensing beam through the above measurement auxiliary information.

[0252] In another example, in a scenario where link 1 is a link between a first network device and a first device, in an embodiment where the first network device sends measurement indication information to the first device to indicate a multiplexing measurement condition, the first device can determine whether a transmit communication beam on link 1 is available for sensing by whether the measurement indication information is received. It can be understood that if the first device can receive the measurement indication information, it can be assumed that the transmit communication beam on link 1 is available for sensing.

[0253] In the embodiment of the present application, the following method may be used to determine whether the currently measured link 1 (communication link) satisfies the second condition.

[0254] Method 1: Determine whether the communication beam of link 1 (communication link) satisfies the second condition based on the relationship between the communication beam of link 1 and the perception target.

[0255] For the received communication beam of link 1, in some embodiments, the first device may determine whether the received communication beam of link 1 satisfies the second condition according to the sensing direction between the sensing target and the first device and the angular coverage of the received communication beam of link 1. The sensing direction between the sensing target and the first device is determined based on the position of the sensing target and the position of the first device. Exemplarily, the first network device may indicate the position of the sensing target by sending information of the sensing target to the first device. For example, the information of the sensing target may be carried in the measurement auxiliary information of the measurement indication information.

[0256] Exemplarily, if the perception direction between the perception target and the first device is within the angular coverage range of the receiving communication beam of link 1, it means that the receiving communication beam of link 1 can be used for perception; if the perception direction between the perception target and the first device is outside the angular coverage range of the receiving communication beam of link 1, it means that the receiving communication beam of link 1 cannot be used for perception.

[0257] In fact, the perception direction between the perception target and the first device can be analogous to the beam pointing of the received perception beam. When the perception direction is within the angular coverage range of the received communication beam of link 1, it means that the received communication beam of link 1 is closer to the received perception beam. In this way, it can be considered that the received communication beam of link 1 can be used for perception.

[0258] Fig.11 is another schematic diagram of a communication scenario provided by an embodiment of the present application. Fig.11 In Figure (a), the direction of the perceived target between the perceived target and the terminal device A (an example of the first device) is within the angular coverage of the receiving communication beam of the communication link A1 (an example of link 1). Therefore, the receiving communication beam of the communication link A1 satisfies the second condition. It should be noted that Fig.11 The receiving communication beam and the sensing direction shown in Figure (a) are only a simple schematic diagram for the sake of understanding the solution, and do not represent the actual receiving communication beam and the sensing direction in physical form.

[0259] The angular coverage of the received communication beam represents the range in which the radiated energy is concentrated within a certain angle. Exemplarily, the angular coverage of the received communication beam can be determined based on the beam pointing and the beam width, and the resulting coverage is within a certain angle centered on the beam pointing and extending outward with 1 / 2 of the beam width. The following explanations of the angular coverage of the transmitted communication beam, the angular coverage of the transmitted perception beam, and the angular coverage of the received perception beam are the same as the explanation of the angular coverage of the received communication beam, and will not be repeated later.

[0260] In some embodiments, the received communication beam of link 1 may be determined based on information of the received communication beam of link 1. Exemplarily, the information of the received communication beam of link 1 includes a beam identifier (such as a beam ID), a beam pointing direction, and a beam width. In other embodiments, the received communication beam of link 1 may also be determined based on parameters of a spatial domain filter for receiving communication signals on link 1.

[0261] Similarly, for the transmission communication beam of link 1, the first device or the communication node that transmits the communication signal can determine whether the transmission communication beam of link 1 meets the second condition based on the sensing direction between the sensing target and the communication node that transmits the communication signal and the angular coverage of the transmission communication beam of link 1. If the sensing direction between the sensing target and the communication node that transmits the communication signal is within the angular coverage of the transmission communication beam of link 1, it means that the transmission communication beam of link 1 can be used for sensing; if the sensing direction between the sensing target and the communication node that transmits the communication signal is outside the angular coverage of the transmission communication beam of link 1, it means that the transmission communication beam cannot be used for sensing.

[0262] In some embodiments, the transmission communication beam of link 1 may be determined based on information of the transmission communication beam of link 1. Exemplarily, the information of the transmission communication beam of link 1 includes a beam identifier (such as a beam ID), a beam pointing direction, and a beam width. In other embodiments, the transmission communication beam of link 1 may also be determined based on parameters of a spatial domain filter for transmitting a communication signal on link 1.

[0263] For the specific description of the transmitting communication beam of link 1, please refer to the relevant description of the receiving communication beam of link 1, which will not be repeated here.

[0264] Method 2: Determine whether the communication beam of link 1 (communication link) satisfies the second condition based on the relationship between the communication beam of link 1 and the sensing area.

[0265] For the received communication beam of link 1, in some embodiments, the first device may determine whether the received communication beam of link 1 meets the second condition according to the angle range between the sensing area and the first device and the angle coverage range of the received communication beam of link 1. The angle range between the sensing area and the first device is determined based on the position of the sensing area and the position of the first device. Exemplarily, the first network device indicates the position of the sensing area by sending information about the sensing area to the first device. For example, the information about the sensing area may be carried in the measurement auxiliary information of the measurement indication information.

[0266] Exemplarily, if the angular range between the sensing area and the first device at least partially overlaps with the angular coverage of the receiving communication beam of link 1, it means that the receiving communication beam of link 1 can be used for sensing; if the angular range between the sensing area and the first device does not overlap with the angular coverage of the receiving communication beam of link 1, it means that the receiving communication beam of link 1 cannot be used for sensing. It should be understood that at least partial overlap described here and below means partial overlap or full overlap, wherein partial overlap means that two angular ranges overlap partially, and full overlap can mean that the two angular ranges are the same, or one of the angular ranges includes the other angular range, such as the angular range between the sensing area and the first device includes the angular coverage of the receiving communication beam.

[0267] In fact, the angular range between the perception area and the first device can be analogous to the angular coverage range of the received perception beam. When the angular range between the perception area and the first device at least partially overlaps with the angular coverage range of the received communication beam of link 1, it means that the received communication beam of link 1 is closer to the received perception beam of link 1. In this way, it can be considered that the received communication beam of link 1 can be used for perception.

[0268] Please refer to Fig.11 In Figure (b), the angle range between the sensing area and the terminal device A (an example of the first device) and the angle coverage range of the receiving communication beam of the communication link A1 (an example of link 1) partially overlap, so the receiving communication beam of the communication link A meets the second condition. It should be noted that Fig.11 The receiving communication beam and angle range shown in Figure (b) are only a simple formal illustration for the sake of understanding the solution, and do not represent the actual receiving communication beam and angle range.

[0269] Similarly, for the transmitted communication beam of link 1, the first device or the communication node that sends the communication signal can determine whether the transmitted communication beam of link 1 meets the second condition based on the angular range between the perception area and the communication node that sends the communication signal and the angular coverage range of the transmitted communication beam of link 1. If the angular range between the perception area and the communication node that sends the communication signal at least partially overlaps with the angular coverage range of the transmitted communication beam of link 1, it means that the transmitted communication beam can be used for perception; if the angular range between the perception area and the communication node that sends the communication signal does not overlap with the angular coverage range of the transmitted communication beam of link 1, it means that the transmitted communication beam cannot be used for perception. For the specific description of the transmitted communication beam of link 1, please refer to the relevant description of the received communication beam of link 1, which will not be repeated here.

[0270] Method 3: Determine whether the communication beam of link 1 (communication link) satisfies the second condition based on the relationship between the communication beam of link 1 and the perception beam.

[0271] In some embodiments, whether the communication beam of link 1 satisfies the second condition is determined based on the angular coverage of the communication beam of link 1 and the angular coverage of the sensing beam.

[0272] In one example, if the angular coverage of the communication beam of link 1 at least partially overlaps with the angular coverage of the perception beam, it means that the communication beam of link 1 can be used for perception; if the angular coverage of the communication beam of link 1 does not overlap with the angular coverage of the perception beam, it means that the communication beam of link 1 cannot be used for perception.

[0273] In another example, if the angular coverage range of the communication beam of link 1 at least partially overlaps with the angular coverage range of the perception beam, and the overlapping range is greater than or equal to the range threshold value, it means that the communication beam of link 1 can be used for perception. Conversely, if the angular coverage range of the communication beam of link 1 does not overlap with the angular coverage range of the perception beam, or the overlapping range is less than the range threshold value, it means that the communication beam of link 1 cannot be used for perception.

[0274] In another example, if the angular coverage range of the communication beam of link 1 at least partially overlaps with the angular coverage range of the perception beam, and the beamforming gain of the overlapping range is greater than or equal to the gain threshold value, it means that the communication beam of link 1 can be used for perception. Conversely, if the angular coverage range of the communication beam of link 1 does not overlap with the angular coverage range of the perception beam, or the beamforming gain of the overlapping range is less than the gain threshold value, it means that the communication beam of link 1 cannot be used for perception.

[0275] For the receiving communication beam of link 1, the first device determines whether the receiving communication beam of link 1 meets the second condition based on the angular coverage of the receiving communication beam of link 1 and the angular coverage of the receiving sensing beam. For the sending communication beam of link 1, the first device or the communication node that sends the communication signal determines whether the sending communication beam of link 1 meets the second condition based on the angular coverage of the sending communication beam of link 1 and the angular coverage of the sending sensing beam. For the specific description of the sending communication beam of link 1, please refer to the relevant description of the receiving communication beam of link 1, which will not be repeated here.

[0276] The above text has given a detailed description of the receiving communication beam on link 1 and the transmitting communication beam on link 1, which will not be repeated here.

[0277] Regarding the received sensing beam, in some embodiments, the received sensing beam may be determined based on information about the received sensing beam, and illustratively, the information about the received sensing beam includes a beam identifier (such as a beam ID), a beam pointing direction, and a beam width. In other embodiments, the received sensing beam may also be determined based on parameters of a spatial domain filter of a received sensing signal.

[0278] Regarding the transmitted perception beam, in some embodiments, the transmitted perception beam may be determined based on information of the transmitted perception beam, and illustratively, the information of the transmitted perception beam includes a beam identifier (such as a beam ID), a beam pointing direction, and a beam width. In other embodiments, the transmitted perception beam may also be determined based on parameters of a spatial domain filter of a transmitted perception signal.

[0279] The third condition is that the scatterer on the communication link is within the sensing area.

[0280] It should be understood that the third condition considers Figures 1 to 3 The scene shown is a scatterer as the sensing target. If the scatterer on the communication link is within the sensing area, it means that the communication link is likely to provide sensing information.

[0281] For the currently measured link 1 (communication link), the first device may determine whether the scatterer on link 1 is within the sensing area. If the scatterer on link 1 is within the sensing area, it means that link 1 may provide sensing information.

[0282] In implementation, the first device determines the position of the scatterer on link 1, and then determines whether the scatterer is located in the sensing area.

[0283] For Figures 1 to 3 The scene with scatterers on the communication link shown is mostly caused by the multipath effect (or multipath phenomenon) of the signal. The multipath effect refers to the reflection, refraction, scattering and other effects of electromagnetic waves on different obstacles (such as buildings, hills, trees, etc.) during the propagation process, resulting in multiple different paths for the same signal to reach the receiving end. The signal components that reach the receiving end through various paths are multipath components. Due to the different path lengths and propagation times, each multipath component will have phase differences and amplitude differences, which will be superimposed on each other to cause interference, causing the original signal to be distorted or errors to occur.

[0284] For the sake of convenience, the link where the multipath effect occurs is called a multipath link, and the multiple paths that the same signal takes to reach the receiving end are called multiple sub-links. The explanation of multipath links and sub-links is the same as here, and will not be repeated later. In addition, the channel formed by multiple paths can be called a multipath channel.

[0285] Fig.12 Schematic diagram of the multipath effect provided by the embodiment of the present application. Fig.12, the communication signal sent by network device A reaches terminal device A through two paths, which can also be called two sub-links: sub-link 11 and sub-link 12. Sub-link 11 and sub-link 12 form link 1 for transmitting the complete communication signal. Link 1 is a multipath link. The signal component that reaches terminal device A through sub-link 11 is multipath component 1, and the signal component that reaches terminal device A through sub-link 12 is multipath component 2. Multipath component 1 and multipath component 2 are superimposed on each other at terminal device A to form the signal received by terminal device A. Terminal device A processes the superimposed signal.

[0286] In the event of a multipath effect on a communication signal, in some embodiments, the first device may determine the position of a scatterer on a sub-link having a scatterer on link 1 which is a multipath link. As long as the scatterer of at least one sub-link (or multipath component) of link 1 is located within the perception area, indicating that there is a scatterer on link 1 located within the perception area, link 1 may be considered to satisfy the third condition, and thus, it may be determined that link 1 may provide perception information.

[0287] For the processing of signals with multipath effects, in order to better analyze and process the multipath effects, the signals can be clustered, that is, multipath components with similar characteristics are grouped into the same cluster. The "cluster" here refers to a group of multipath components that arrive close in time and have similar delays and angles of arrival (AOA). The center position of each cluster is called the cluster center position, which usually corresponds to the path with the maximum signal strength or the minimum delay in the cluster. The cluster center position area refers to a spatial area within a certain range around the cluster center position, and the signal propagation characteristics within this area are relatively consistent.

[0288] Therefore, in some embodiments, the first device can calculate the cluster center position of each cluster in the multiple clusters of the communication signal transmitted on link 1. For the cluster with scatterers, the cluster center position of each cluster is roughly the position of the scatterer. In this way, as long as the cluster center position of at least one cluster in the cluster with scatterers is located in the sensing area, it can be determined that at least one scatterer of link 1 is located in the sensing area, and link 1 meets the third condition. Fig.12 For example, the communication signal transmitted on link 1 has two clusters, and the cluster center position of one cluster is roughly the position of the scatterer. Therefore, it can be determined that a scatterer of link 1 is located in the sensing area, and link 1 meets the third condition.

[0289] In one example, the ratio of the overlapping area of ​​the cluster center position area and the perception area of ​​the cluster with the scatterer to the minimum value of the perception area and the cluster center position area can be used to determine whether the scatterer is within the perception area, such as (cluster center position area ∩ perception area) / min (cluster center position area, perception area). When the ratio of the overlapping area of ​​the two to the minimum value of the two is greater than a threshold, it can be considered that the scatterer is within the perception area.

[0290] In an embodiment of determining whether link 1 satisfies the third condition, the first network device may send information of the perception area to the first device, where the information of the perception area includes location information indicating the location of the perception area, for example, the information of the perception area is carried in measurement assistance information of the measurement indication information.

[0291] Fourth condition: the distance between the communication node on the communication link and the center position of the perception area is less than the first threshold, or the distance between the communication node on the communication link and the perception target is less than the second threshold.

[0292] The fourth condition considers the distance between the communication node on the communication link and the perception area (or perception target). The smaller the distance, the more likely the communication link is to provide perception information. Conversely, the larger the distance, the less likely the communication link is to provide perception information.

[0293] In the embodiment where the fourth condition is that the distance between the communication node of the communication link and the center position of the perception area is less than the first threshold, for the first device of link 1 (communication link), the first device determines whether the distance between itself and the center position of the perception area is less than the first threshold, and when the distance between the two is less than the first threshold, link 1 satisfies the fourth condition. In some scenarios, the communication node is located in the perception area, and the communication node may be a perception target or may not be a perception target.

[0294] Exemplarily, the first network device may send information about the sensing area to the first device, where the information about the sensing area includes location information for indicating a location of the sensing area. For example, the information about the sensing area is carried in measurement assistance information of the measurement indication information.

[0295] In the embodiment where the fourth condition is that the distance between the communication node of the communication link and the center position of the perception target is less than the second threshold, for the first device of link 1 (communication link), the first device determines whether the distance between itself and the center position of the perception target is less than the second threshold, and when the distance between the two is less than the second threshold, link 1 satisfies the fourth condition. In some scenarios, when the distance between the communication node and the perception target is almost 0, the communication node is the perception target.

[0296] Exemplarily, the first network device may send information of the perception target to the first device, where the information of the perception target includes location information for indicating the location of the perception target. For example, the information of the perception target is carried in measurement auxiliary information of the measurement indication information.

[0297] Above, each condition in the first category of conditions in the embodiment of the present application is described in detail. It should be understood that each condition in the first category of conditions in the above example and the method of performing link measurement based on each condition are only for illustrative purposes, and link measurement can be performed based on more conditions and more methods in implementation, which should not be construed as limiting the embodiment of the present application.

[0298] It should also be understood that the various conditions of the first category of conditions described above can have multiple combinations based on actual scenarios. For example, the first category of conditions can be a combination of one or more conditions other than the first condition. The first category of conditions can be a combination of one or more conditions other than the third condition.

[0299] The second type of conditions

[0300] As mentioned above, the second type of condition focuses on the characteristics of the communication channel of the communication link. Taking link 1 (communication link) as an example, if the currently measured link 1 meets the first type of condition, it means that link 1 can provide perception information, but if the channel condition of the communication channel of link 1 is not ideal, it will also affect the perception effect. Therefore, the communication link can be further measured in combination with the second type of condition.

[0301] For the second type of conditions, the relevant parameters of the communication signal transmitted on the communication link can be used to evaluate the characteristics of the communication channel. Below, the signal quality, Doppler shift and power of the communication signal are used as parameters for evaluating the characteristics of the communication channel as an example to specifically illustrate the second type of conditions. It should be understood that other parameters for evaluating the characteristics of the communication channel can also be used as the measurement basis of the second type of conditions, and the embodiments of the present application do not make any limitation.

[0302] Fifth condition: the signal quality of the communication signal transmitted on the communication link is greater than or equal to the signal quality threshold.

[0303] It should be understood that if the signal quality of the communication signal transmitted on the communication link is greater than or equal to the signal quality threshold, it means that the channel condition of the communication channel of the communication link is relatively ideal, further increasing the possibility that the communication link can be used for perception.

[0304] For link 1 currently measured by the first device, the signal quality of the communication signal received on link 1 is compared with the signal quality threshold. If the signal quality of the received communication signal is greater than or equal to the signal quality threshold, it means that the channel condition of the communication channel of link 1 is relatively ideal.

[0305] Exemplarily, the signal quality can be represented by at least one of the following parameters: signal strength, signal-to-noise ratio (SNR), signal to interference plus noise ratio (SINR), reference signal received power (RSRP), and reference signal received quality (RSRQ).

[0306] It should be understood that different parameters correspond to different signal quality thresholds. For example, if the signal quality is represented by SNR and signal strength, then the signal quality threshold includes the SNR threshold and the signal strength threshold.

[0307] The sixth condition is that the maximum Doppler frequency shift of the communication signal transmitted on the communication link is less than or equal to the Doppler frequency shift threshold.

[0308] Doppler shift represents the fading rate of the channel. When a mobile station (such as a mobile phone, communication equipment on a train, etc.) moves at a constant rate, the frequency of the received signal will change due to the Doppler effect. This rate of change is the Doppler shift. In high-speed mobile scenarios such as high-speed railways, Doppler shift is particularly obvious because it directly affects the stability and reliability of the signal. In this way, the Doppler shift can be used to measure the rate of change of the channel. If the rate of change of the channel is too fast, it means that the channel is not suitable.

[0309] Therefore, for link 1 currently measured by the first device, the maximum Doppler frequency shift among the Doppler frequency shifts of the communication signal received on link 1 is compared with the Doppler frequency shift threshold. If the maximum Doppler frequency shift of the received communication signal is less than or equal to the Doppler frequency shift threshold, it means that the channel condition of the communication channel of link 1 is relatively ideal, further increasing the possibility that link 1 can be used for perception.

[0310] The seventh condition: when the communication link is a multipath link, the power of each sublink in at least one sublink of the communication link is greater than or equal to the power threshold, or the power ratio of the power of each sublink in at least one sublink of the communication link to the power of the communication link is greater than or equal to the power ratio threshold.

[0311] It should be understood that the power of the sublink described here represents the power of the communication signal received on the sublink. Among them, the communication signal received on the sublink can be called a multipath component. For the relevant explanation of the multipath link and the sublink, please refer to the relevant description above.

[0312] It should also be understood that if a communication link as a multipath link satisfies the seventh condition, it means that the channel condition of the communication channel of the communication link is relatively ideal, further increasing the possibility that the communication link can be used for sensing.

[0313] For link 1 currently measured by the first device, link 1 is a multipath link, and the power of each of the multiple sublinks of link 1 is compared with the power threshold. If the power of each sublink in at least one sublink of link 1 is greater than or equal to the power threshold, it means that the channel condition of the communication channel of link 1 is relatively ideal; or, the power ratio of the power of each sublink in the multiple sublinks of link 1 to the power of link 1 is compared with the power ratio threshold. If the power ratio of the power of each sublink in at least one sublink of link 1 to the power of link 1 is greater than or equal to the power ratio threshold, it means that the channel condition of the communication channel of link 1 is relatively ideal, further increasing the possibility that link 1 can be used for perception.

[0314] Taking the power ratio of the power of a sublink to the power of a link as an example, for example, after the multipath effect occurs in link 1, three sublinks are formed, and the first device measures link 1. Sublink 1 and sublink 2 meet the first type of conditions, and the power ratio of the power of sublink 1 to the power of link 1 is greater than or equal to the power ratio threshold, and the power ratio of the power of sublink 2 to the power of link 1 is greater than or equal to the power ratio threshold. In this way, it can be considered that link 1 meets the seventh condition. Among them, the power of the sublink or the power ratio of the sublink to link 1 can be determined by the channel gain of the sublink.

[0315] The eighth condition: when the communication link is a multipath link, the signal quality of the communication signal received on each sub-link in at least one sub-link of the communication link is greater than or equal to the signal quality threshold.

[0316] It should be understood that if a communication link as a multipath link satisfies the eighth condition, it means that the channel condition of the communication channel of the communication link is relatively ideal, which further increases the possibility that the communication link can be used for perception.

[0317] For link 1 currently measured by the first device, link 1 is a multipath link, and the signal quality of the communication signal received on each of the multiple sub-links of link 1 is compared with the signal quality threshold. If the signal quality of the communication signal received on each sub-link in at least one sub-link of link 1 is greater than or equal to the signal quality threshold, it means that the channel condition of the communication channel of link 1 is relatively ideal, further increasing the possibility that link 1 can be used for perception.

[0318] Continuing with the example of link 1 including three sublinks, sublink 1 and sublink 2 meet the first type of conditions, the signal quality of the communication signal received on sublink 1 is greater than or equal to the signal quality threshold, and the signal quality of the communication signal received on sublink 2 is greater than or equal to the signal quality threshold, so it can be considered that link 1 meets the eighth condition. Among them, the signal quality of the sublink can be determined by the sub-power or the power ratio of the sublink to link 1, and the power of the sublink or the power ratio of the sublink to link 1 can be determined by the channel gain of the sublink.

[0319] Ninth condition: when the communication link is a multipath link, the maximum Doppler frequency shift of the communication signal received on each sub-link in at least one sub-link of the communication link is less than or equal to the Doppler frequency shift threshold.

[0320] It should be understood that if a communication link as a multipath link satisfies the ninth condition, it means that the channel condition of the communication channel of the communication link is relatively ideal, which further increases the possibility that the communication link can be used for perception.

[0321] For link 1 currently measured by the first device, link 1 is a multipath link, and the maximum Doppler shift of the Doppler shift of the communication signal received on each sublink in the multiple sublinks of link 1 is compared with the Doppler shift threshold. If the maximum Doppler shift of the communication signal received on each sublink in at least one sublink of link 1 is less than or equal to the Doppler shift threshold, it means that the channel condition of the communication channel of link 1 is relatively ideal, further increasing the possibility that link 1 can be used for perception. Continuing with the above example that link 1 includes 3 sublinks, the maximum Doppler shift of the communication signal received on sublink 1 is less than or equal to the Doppler shift threshold, and the maximum Doppler shift of the communication signal received on sublink 2 is less than or equal to the Doppler shift threshold. In this way, it can be considered that link 1 meets the ninth condition.

[0322] It should be understood that the seventh condition, the eighth condition and the ninth condition mentioned above are applicable to the scenario where the communication link is a multipath link. In implementation, the first device selects applicable conditions to measure link 1 based on the actual situation of link 1.

[0323] Above, each condition in the second category of conditions in the embodiment of the present application is described in detail.

[0324] It should be understood that the various conditions of the second category of conditions in the above examples and the methods of performing link measurement based on the various conditions are merely illustrative, and link measurement can be performed based on more conditions and in more methods in implementation, and should not constitute a limitation to the embodiments of the present application.

[0325] The first device measures link 1 (communication link) based on the multiplexing measurement condition, and determines whether link 1 can be used for sensing based on the measurement result obtained by the measurement, so as to send a measurement report. In some embodiments, based on different measurement situations, the first device sends or does not send a measurement report, and in the case of sending a measurement report, the measurement report sent is also different. In the case of sending a measurement report, the first device executes step S131, that is, the first device sends a measurement report to the first network device, and in the case of not sending a measurement report, the first device does not send (or prohibits sending) a measurement report.

[0326] Next, taking the multiplexing measurement conditions including the first type of conditions and the second type of conditions as an example, combined with the situation where the first device measures link 1 based on the multiplexing measurement conditions, whether the first device sends a measurement report and the specific content of the measurement report are specifically explained.

[0327] Fig.13 It is a schematic flowchart of a process for performing link measurement based on multiplexing measurement conditions to determine whether a communication link is available for perception, provided in an embodiment of the present application.

[0328] In an embodiment where the multiplexed measurement conditions include first-type conditions and second-type conditions, the first device measures link 1 based on the first-type conditions and the second-type conditions, and there are three results (hereinafter referred to as case 1, case 2, and case 3), and the first device performs different steps based on different situations.

[0329] Case 1: Link 1 (communication link) meets the first and second conditions

[0330] When the first device determines that link 1 (communication link) satisfies the first type of condition and the second type of condition, the first device determines that link 1 can be used for sensing, and thus, the first device sends a measurement report of link 1. The measurement report includes multiplexing indication information, and the multiplexing indication information is used to indicate that link 1 can be used for sensing. Exemplarily, the multiplexing indication information can be acknowledgment (ACK) information. Thus, after receiving the measurement report including the multiplexing indication information indicating that link 1 can be used for sensing, the first network device can determine that link 1 satisfies the first type of condition and the second type of condition.

[0331] refer to Fig.13In the implementation, exemplarily, in step S131a, the first device determines whether link 1 satisfies the first type of condition. When link 1 satisfies the first type of condition, in step S131b, the first device determines whether link 1 satisfies the second type of condition. When link 1 satisfies the second type of condition, the first device determines that link 1 can be used for perception. Correspondingly, the first device executes step S1311. In step S1311, the first device sends a measurement report to the first network device, and the measurement report includes multiplexing indication information for indicating that link 1 can be used for perception. For example, the multiplexing indication information can be ACK information.

[0332] It should be noted that link 1 satisfying the first type of conditions means that link 1 satisfies all conditions of the first type of conditions indicated by the measurement indication information, and link 1 satisfying the second type of conditions means that link 1 satisfies all conditions of the second type of conditions indicated by the measurement indication information.

[0333] In the above situation 1, in some embodiments, the measurement report includes not only multiplexing indication information (such as ACK information) for indicating that link 1 can be used for perception, but also perception auxiliary information, so that the first network device can further determine whether link 1 meets the perception requirement based on the perception auxiliary information, so as to finally determine whether link 1 can be used for perception. Here, the perception requirement focuses on the measurement of the three dimensions of distance measurement, speed measurement and angle measurement of the perception task. The main indicators of the perception requirement include indicators such as unambiguous range, resolution, measurement accuracy and channel change rate. For the specific description of the perception requirement, please refer to the relevant description below, which will not be repeated here.

[0334] Exemplarily, the perception assistance information includes at least one of the following information.

[0335] The information of the receiving communication beam on link 1 (recorded as the first communication beam), where the receiving communication beam on link 1 and the first communication beam can be described interchangeably, represents the communication beam that receives the communication signal on link 1. Exemplarily, the information of the receiving communication beam on link 1 may include a beam identifier (such as a beam ID), a beam width, and a beam pointing direction.

[0336] The first Doppler frequency shift information is used to indicate the maximum Doppler frequency shift and / or Doppler spread of the communication signal received on link 1.

[0337] The first signal information is used to indicate the signal quality of the communication signal received on link 1.

[0338] The second signal information, when link 1 is a multipath link, is used to indicate the signal quality of the communication signal received on the sublink that meets the multiplexing measurement condition in link 1. For example, after the multipath effect occurs in link 1, three sublinks are formed, sublink 1 and sublink 2 meet the multiplexing measurement condition, and sublink 3 does not meet the multiplexing measurement condition. The second signal information is used to indicate the signal quality of the communication signal received on sublink 1 and sublink 2. When indicating the signal quality of each sublink, illustratively, a differential method can be used for indication, and the differential benchmark can be the minimum value of the signal quality among multiple sublinks, or it can be the signal quality of the communication signal received on link 1, etc., and no limitation is made here.

[0339] Power information, when link 1 is a multipath link, the power information is used to indicate the power ratio of the power of the sub-links in link 1 that meet the multiplexing measurement conditions to the power of link 1. Continuing with the above example that link 1 includes 3 sub-links, the power information is used to indicate the power ratio of the power of sub-link 1 to the power of link 1 and the power ratio of the power of sub-link 2 to the power of link 1, or the power information is used to indicate the power ratio of the sum of the power of sub-link 1 and the power of sub-link 2 to the power of link 1.

[0340] The second Doppler frequency shift information, when link 1 is a multipath link, is used to indicate the Doppler frequency shift of the communication signal received on the sub-link that meets the multiplexing measurement condition in link 1. Continuing to take the above example that link 1 includes 3 sub-links, the second Doppler frequency shift information is used to indicate the Doppler frequency shift of the communication signal received on sub-link 1 and sub-link 2.

[0341] In the case where link 1 is a multipath link, the second signal information can be obtained through the first signal information and the power information. Therefore, in the case where link 1 is a multipath link, the combination of the first signal information and the power information and the second signal information can be carried in the perception assistance information to determine the signal quality of the communication signal received on the link that meets the multiplexing measurement condition in link 1.

[0342] It should be noted that, in addition to the information of the received communication beam (recorded as the first communication beam) on link 1, the type of information included in the perception assistance information is related to the type of conditions included in the second category of conditions above. For example, the second category of conditions includes the fifth to ninth conditions. When link 1 is a multipath link, the perception assistance information includes at least the second signal information and the second Doppler frequency shift information, or the perception assistance information includes the first signal information, power information and the second Doppler frequency shift information. Exemplarily, the perception assistance information may also include the first signal information and the first Doppler frequency shift information. For another example, the second category of conditions includes the fifth to ninth conditions. When link 1 is not a multipath link, the perception assistance information includes the first signal information and the first Doppler frequency shift information.

[0343] It should also be noted that, for link 1 measured by the first device, when link 1 is a multipath link, the multipath components received by the first device from each sublink (or multiple paths) are superimposed to form a received communication signal, and the first device measures link 1 as a whole through the superimposed communication signal, and can obtain the measurement results of each sublink. For example, as long as at least one sublink in the measured link 1 meets the multiplexing measurement condition, link 1 is considered to be usable for sensing, and the relevant information of the sublink that meets the condition is reported.

[0344] Case 2: Link 1 (communication link) meets the first condition but does not meet the second condition

[0345] When the first device determines that link 1 (communication link) satisfies the first type of condition and does not satisfy the second type of condition, it means that the spatial resources of link 1 can be used for sensing, but the channel conditions of the communication channel do not satisfy the conditions. Therefore, the first device determines that link 1 is not available for sensing. In this way, the first device sends a measurement report, and the measurement report includes multiplexing indication information. The multiplexing indication information is used to indicate that link 1 is not available for sensing. Exemplarily, the multiplexing indication information can be negative acknowledgment (NACK) information. In this way, after receiving the measurement report including the multiplexing indication information indicating that link 1 is not available for sensing, the first network device can determine that link 1 is not available for sensing. More specifically, it can determine that link 1 satisfies the first type of condition and does not satisfy the second type of condition, that is, it is determined that the channel conditions of the communication channel of link 1 do not satisfy the conditions.

[0346] refer to Fig.13In the implementation, exemplarily, in step S131a, the first device determines whether link 1 satisfies the first type of condition. When link 1 satisfies the first type of condition, in step S131b, the first device determines whether link 1 satisfies the second type of condition. When link 1 does not satisfy the second type of condition, the first device determines that link 1 is not available for perception. Correspondingly, the first device executes step S1312. In step 1312, the first device sends a measurement report to the first network device, and the measurement report includes multiplexing indication information for indicating that link 1 is not available for perception. For example, the multiplexing indication information may be NACK information.

[0347] It should be noted that link 1 not satisfying the second type of condition means that link 1 does not satisfy at least one condition of the second type of condition. For example, taking the second type of condition including the fifth condition and the sixth condition as an example, if link 1 does not satisfy at least one of the fifth condition and the sixth condition, it is considered that link 1 does not satisfy the second type of condition.

[0348] Case 3: Link 1 (communication link) does not meet the first condition

[0349] When the first device determines that link 1 (communication link) does not satisfy the first type of condition, it means that link 1 cannot provide perception information. Therefore, when the first device determines that link 1 does not satisfy the first type of condition, it can determine that link 1 is not available for perception. In this way, illustratively, the first device does not send a measurement report. When the first network device does not receive a measurement report within a preset time period, it can determine that link 1 is not available for perception, and more specifically, determine that link 1 does not satisfy the first type of condition.

[0350] refer to Fig.13 , in the implementation, exemplarily, in step S131a, the first device determines whether link 1 satisfies the first type of condition. If link 1 does not satisfy the first type of condition, the first device does not send a measurement report.

[0351] It should be noted that link 1 not satisfying the first type of condition means that link 1 does not satisfy at least one condition of the first type of condition. For example, taking the first type of condition including the second condition, the third condition and the fourth condition as an example, if link 1 does not satisfy at least one of the three conditions, then it is considered that link 1 does not satisfy the first type of condition.

[0352] In the step of sending a measurement report by the first device (such as step S1311 or step 1312), in some other embodiments, the measurement report not only includes multiplexing indication information for indicating whether link 1 can be used for perception, but also includes measurement results obtained by measuring link 1, and the embodiments of the present application do not impose any limitation thereto.

[0353] In one example, the measurement result of link 1 includes the results corresponding to each condition obtained by measuring each condition, and the result corresponding to each condition may include a measurement value. Exemplarily, the result corresponding to each condition also includes indication information for indicating whether link 1 satisfies the condition. In another example, the measurement result includes indication information for indicating at least one condition satisfied by link 1, and may also include the measurement value corresponding to each condition in the at least one condition.

[0354] In step S140 , the first network device determines a scheduling strategy for resources of link 1 .

[0355] In this step, the first network device determines a scheduling strategy for resources of link 1 based on the situation that the first device measures link 1. The scheduling strategy for resources of link 1 is specifically described below based on the above three situations.

[0356] Scheduling strategy for case 1

[0357] Continue to refer Fig.13 In case 1, in step S1311, the first device sends a measurement report to the first network device, and correspondingly, the first network device receives the measurement report. The measurement report includes multiplexing indication information, such as ACK information, for indicating that link 1 is perceptible. In some embodiments, the measurement report also includes perceptual assistance information.

[0358] In step S141, the first network device determines whether link 1 meets the sensing requirement according to the received measurement report.

[0359] In the above situation 1, the first network device receives the measurement report, obtains the multiplexing indication information and the perception auxiliary information, and determines that link 1 can be used for perception according to the multiplexing indication information, and then determines whether link 1 meets the perception requirement according to the perception auxiliary information. For the specific description of the perception auxiliary information, please refer to the relevant description of the perception auxiliary information in the above situation 1, which will not be repeated here.

[0360] It should be understood that although the result obtained by the first device based on the multiplexing measurement condition for link 1 is that link 1 can be used for sensing, the multiplexing measurement condition considers more the characteristics of the channel and whether the airspace resources are available, and does not consider whether link 1 meets the sensing requirements. It can be understood that if link 1 does not meet the sensing requirements, the sensing result obtained by sensing the sensing target does not actually meet the requirements, so link 1 cannot be used for sensing in the end.

[0361] In some embodiments, the main indicators of the sensing requirements include, but are not limited to, unambiguous range, resolution, measurement accuracy, channel change rate, etc. Exemplarily, the sensing requirements include at least one of the following: the unambiguous range is within a preset range; the resolution is greater than or equal to the resolution threshold; the measurement accuracy is greater than or equal to the measurement accuracy threshold; the channel change rate meets the requirements.

[0362] Perception requirements focus on the measurement of three dimensions of perception tasks: distance measurement, speed measurement, and angle measurement.

[0363] Exemplarily, the unambiguous range may include an unambiguous range of speed (referred to as unambiguous speed range), an unambiguous range of distance (referred to as unambiguous distance range) and an unambiguous range of angle (referred to as unambiguous angle range). Correspondingly, the preset range includes a speed preset range, a distance preset range and an angle preset range.

[0364] Exemplarily, the resolution includes speed resolution, distance resolution and angle resolution, and correspondingly, the resolution threshold includes speed resolution threshold, distance resolution threshold and angle resolution threshold.

[0365] Exemplarily, the measurement accuracy includes speed measurement accuracy, distance measurement accuracy and angle measurement accuracy. Correspondingly, the measurement accuracy threshold includes speed measurement accuracy threshold, distance measurement accuracy threshold and angle measurement accuracy threshold.

[0366] In this way, the first network device determines the values ​​of various indicators related to the perception requirement based on the perception auxiliary information, and compares the values ​​of various indicators with the corresponding thresholds. When the values ​​of various indicators meet the corresponding thresholds, it can be finally determined that link 1 can be used for perception. When the value of at least one of the values ​​of various indicators does not meet the corresponding threshold, it can be finally determined that link 1 cannot be used for perception. For example, the perception requirement includes the 4 items in the above example. Therefore, based on the perception auxiliary information, the unambiguity range, resolution, measurement accuracy and channel change rate for perception in link 1 are determined. When the unambiguity range is within the preset range, the resolution is greater than or equal to the resolution threshold, the measurement accuracy is greater than or equal to the measurement accuracy threshold, and the channel change rate meets the requirements, it can be finally determined that link 1 can be used for perception. On the contrary, when at least one of the unambiguity range, resolution and measurement accuracy does not meet the corresponding threshold, it can be finally determined that link 1 cannot be used for perception.

[0367] Take the perception mode of A sending and B receiving as an example.

[0368] Regarding resolution, for example, the distance resolution can be determined according to the bandwidth and the bistatic angle, the speed resolution can be determined according to the wavelength, the sensing symbol period, the number of sensing symbols, etc., and the angle resolution can be determined according to the wavelength and the aperture of the array. Among them, the bandwidth and wavelength can be determined according to the frequency domain information of link 1, the bistatic angle can be determined according to the information of the receiving communication beam (first communication beam) on link 1 and the information of the transmitting communication beam on link 1, and the sensing symbol period and the number of sensing symbols can be determined according to the time domain information of link 1.

[0369] Regarding the unambiguous range, illustratively, the unambiguous distance range can be determined according to the frequency domain sampling interval and the bistatic angle of the communication signal, the unambiguous speed range can be determined according to the wavelength, the communication signal period and the bistatic angle, and the unambiguous angle range can be determined according to the wavelength and the antenna spacing. Among them, the frequency domain sampling interval and the wavelength can be determined according to the frequency domain information of link 1.

[0370] Regarding measurement accuracy, exemplarily, the distance measurement accuracy can be determined based on the distance resolution and SNR, the speed measurement accuracy can be determined based on the speed resolution and SNR, and the angle measurement accuracy can be determined based on the angle resolution and SNR, wherein the SNR can be determined based on the above-mentioned first signal information, or based on the second signal information, or based on the first signal information and power information, depending on whether multipath effect occurs in link 1.

[0371] The channel change rate is determined by the first Doppler frequency shift information or the second Doppler frequency shift information.

[0372] For the specific process of determining the resolution, unambiguous range, measurement accuracy and channel change rate, please refer to the description of the relevant technology and will not be repeated here.

[0373] In the above process, when link 1 meets the first and second conditions, the process of further determining whether link 1 meets the perception requirements is actually a process of further measuring link 1. By using the first network device to determine whether link 1 meets the perception requirements, for the scenario where the first device is a terminal device, it can effectively reduce the power consumption of the terminal device and the signaling overhead of the air interface.

[0374] In the case where it is determined based on step S141 that link 1 meets the perception requirement (recorded as case 1.1), it can be finally determined that link 1 can be used for perception. Therefore, in step S1421, the first network device determines that the scheduling strategy of the resources of link 1 is scheduling strategy 1. Scheduling strategy 1 is used to indicate that the communication resources of link 1 can be used for perception. In this way, the communication resources of link 1 can actually be used as communication perception resources. When perceiving, perception can be performed based on the transmission of communication signals on the communication resources of link 1. In this way, since the communication resources of link 1 can be used not only for communication but also for perception, there is no need to configure additional perception resources. Therefore, resource utilization can be effectively improved and wireless resources can be maximized.

[0375] In the case where link 1 does not meet the sensing requirement based on step S141 (recorded as case 1.2), it can be finally determined that link 1 is not available for sensing, so in step S1422, the first network device determines that the scheduling strategy for the resources of link 1 is scheduling strategy 2. Scheduling strategy 2 is used to indicate that the sensing resources are orthogonal to the communication resources of link 1 in the time domain and / or frequency domain.

[0376] It can be understood that since the final determined link 1 is not available for perception, but link 1 satisfies the first and second conditions, it means that the relevant perception resources and the communication resources of link 1 can overlap at least in the spatial domain, but if the relevant perception resources overlap with the communication resources of link 1 in the time domain and frequency domain, perception and communication will interfere with each other. Therefore, the perception resources and the communication resources of link 1 need to be orthogonal in the time domain and / or frequency domain to avoid interference.

[0377] Scheduling strategy for case 2

[0378] refer to Fig.13 In case 2, in step S1312, the first device sends a measurement report to the first network device, and correspondingly, the first network device receives the measurement report. The measurement report includes multiplexing indication information, such as NACK information, for indicating that link 1 is not available for sensing.

[0379] Based on the multiplexing indication information in the received measurement report, the first network device can determine that link 1 is not available for sensing, and more specifically, it can be determined that link 1 meets the first type of conditions and does not meet the second type of conditions, that is, it is determined that the channel condition of link 1 is not ideal. In this way, the relevant sensing resources and the communication resources of link 1 can overlap in the spatial domain, but if the relevant sensing resources overlap with the communication resources of link 1 in the time domain and frequency domain, sensing and communication will interfere with each other. Therefore, the sensing resources and the communication resources of link 1 need to be orthogonal in the time domain and / or frequency domain to avoid interference.

[0380] Therefore, in step S1422, the first network device determines that the scheduling policy for the resources of link 1 is scheduling policy 2. For a detailed description of scheduling policy 2, reference may be made to the above related description, which will not be repeated here.

[0381] Scheduling strategy for case 3

[0382] refer to Fig.13 In case 3, the first device does not send (or prohibits sending) a measurement report, and correspondingly, the first network device does not receive the measurement report. Therefore, when the first network device does not receive the measurement report, it can be determined that link 1 is not available for sensing, and more specifically, it can be determined that link 1 does not meet the first type of conditions, that is, the spatial resources of link 1 are not available for sensing. In this way, the relevant sensing resources are orthogonal to the communication resources of link 1 in the spatial domain, which means that the two can overlap or not overlap in the time domain and frequency domain, and do not affect each other.

[0383] Therefore, in step S1423, the first network device determines that the scheduling strategy for the resources of link 1 is scheduling strategy 3. Scheduling strategy 3 is used to indicate that the sensing resources and the communication resources of link 1 do not affect each other in the time domain and / or frequency domain. It should be understood that the "no influence" here means that the sensing resources and the communication resources of link 1 may overlap or may not overlap in the time domain and / or frequency domain.

[0384] It should be understood that the process of the first network device determining the scheduling strategy of the resources of link 1 in the above example is only for illustrative purposes.

[0385] In other embodiments, when the first network device determines the scheduling strategy based on the received measurement report, it is not necessary to further determine whether link 1 meets the perception requirement, that is, skip step S141, and directly determine the scheduling strategy based on the multiplexing indication information in the measurement report. Specifically, when the multiplexing indication information in the measurement report is used to indicate that link 1 can be used for perception, the first network device directly determines that the scheduling strategy for the resources of link 1 is scheduling strategy 1.

[0386] Will Fig.13 and Fig. 9 Combined, Fig. 9 Step S131 includes Fig.13 Step S1311 or step S1312, Fig. 9 Step S140 includes Fig.13 In step S1421, step S1422 or step S1423, the logical relationship between each step shall be based on its internal logical relationship.

[0387] In step S150, the first network device sends scheduling information.

[0388] In this step, the first network device determines and sends scheduling information based on the scheduling strategy of the communication resources of the determined link 1. The scheduling information indicates the scheduled resources (recorded as resource 1), and resource 1 includes at least one resource: a perception-only resource, a communication-only resource, and a communication-aware resource.

[0389] Here, perception-only resources, communication-only resources, and communication-aware resources represent the types of resources.

[0390] Perception-only resources refer to resources used only for perception, communication-only resources refer to resources used only for communication, and communication-aware resources refer to resources used for both communication and perception. In addition, perception-only resources, communication-only resources, and communication-aware resources all involve the time domain, frequency domain, and spatial domain. For example, perception-only resources are used only for perception, which means that resources work together in the time domain, frequency domain, and spatial domain for perception only; communication-aware resources refer to resources that work together in the time domain, frequency domain, and spatial domain for communication and perception.

[0391] In some embodiments, the scheduling information schedules resources for sensing (i.e., sensing resources). Thus, there are three possible situations for resource 1: resource 1 includes sensing resources only, or resource 1 includes sensing resources only and communication sensing resources, or resource 1 includes communication sensing resources. Among them, resource 1 includes sensing resources only and communication sensing resources, which means that part of resource 1 is sensing resources only, and the other part is communication sensing resources.

[0392] In other embodiments, the scheduling information schedules resources used for communication (i.e., communication resources). Thus, there are three possible situations for resource 1: resource 1 includes only communication resources, or resource 1 includes only communication resources and communication-aware resources, or resource 1 includes communication-aware resources.

[0393] As a device that determines resource scheduling, the first network device will not only schedule resources for the first device based on the scheduling strategy of the resources of the determined link 1, but will also schedule resources in combination with the resources of all devices connected to the first network device and different services. Therefore, the resource 1 finally scheduled for the first device may be different from the scheduling strategy determined based on the link measurement, and the two are not absolutely related. However, it can be understood that the scheme of measuring the communication link based on the reuse measurement condition in the embodiment of the present application to determine whether the communication resources of the link are used for perception can provide a reuse basis for the scheduling of communication and perception resources, that is, the first network device can schedule communication and perception resources based on the results of measuring the communication link. In this way, the resources finally scheduled for the first device by the first network device may include reused communication perception resources. In this way, while maintaining the normal progress of communication and perception as much as possible, the utilization rate of resources can be improved to maximize the utilization of wireless resources, thereby improving system performance.

[0394] For example, the scheduling strategy for the resources of link 1 is scheduling strategy 1, that is, the communication resources of link 1 can be used for perception, that is, without considering other factors, the communication resources of link 1 can actually be used as communication perception resources for communication and perception, but, in combination with the scheduling of resources of other devices connected to the first network device, or in combination with the measurement results of other links, the resources 1 scheduled for the first device does not necessarily include the communication resources of link 1, and even if the resources 1 include the communication resources of link 1, the communication resources of link 1 are not necessarily used for perception.

[0395] Since resource reuse is taken into consideration, in order to facilitate the distinction of functions of different resources, the embodiment of the present application also makes relevant designs for scheduling information.

[0396] In some embodiments, the scheduling information is used to indicate the function of resource 1, specifically, resource 1 is used only for communication, or resource 1 is used only for sensing, or at least part of resource 1 is used for communication and sensing.

[0397] Among them, at least part of the resources of resource 1 are used for communication and perception, which means that part of the resources or all of the resources of resource 1 are used for perception and communication, and the resources in resource 1 used for perception and communication are communication perception resources. When part of the resources of resource 1 are used for perception and communication, the other part of the resources are only used for perception or only for communication. For example, when the scheduling information schedules perception resources, resource 1 may include two parts of resources, one part of the resources is perception-only resources used only for perception, and the other part of the resources is communication perception resources used for perception and communication. For another example, when the scheduling information schedules communication resources, resource 1 may include two parts of resources, one part of the resources is communication-only resources used only for communication, and the other part of the resources is communication perception resources used for perception and communication. When all the resources of resource 1 are used for perception and communication, the entire resource 1 is a communication perception resource.

[0398] Exemplarily, the scheduling information indicates the purpose of resource 1 in the following manners.

[0399] Method A

[0400] In mode A, the scheduling information includes purpose information, which is used to determine three functions of resource 1: resource 1 is used only for communication, or resource 1 is used only for sensing, or at least part of resource 1 is used for communication and sensing.

[0401] In some embodiments, the target information includes 2 bits, and different values ​​of the 2 bits may be used to directly indicate the function of the resource 1 .

[0402] 2 bits can represent four binary values: 00, 01, 10, and 11. Therefore, any three of the four values ​​can be used to represent the three functions of resource 1. For example, 01 represents only sensing, 10 represents only communication, and 11 represents both sensing and communication. For another example, 01 represents only sensing, 10 represents only communication, and 11 represents both sensing and communication.

[0403] In the case where the resource 1 scheduled by the scheduling information includes sensing-only resources, the target information is used to indicate that the resource 1 is used only for sensing.

[0404] In the case where the resource 1 scheduled by the scheduling information includes communication-only resources, the target information is used to indicate that the resource 1 is used only for communication.

[0405] When resource 1 scheduled by the scheduling information includes only communication resources and communication-aware resources, or includes only perception resources and communication-aware resources, or includes communication-aware resources, the target information is used to indicate that at least part of resource 1 is used for communication and perception.

[0406] In some other embodiments, the target information includes 1 bit, and different values ​​of the 1 bit may be used to determine the function of the resource 1 .

[0407] In one example, in an embodiment where the scheduling information schedules communication resources, for resource 1 currently scheduled by the scheduling information, 1 (or 0) is used to indicate that resource 1 is available for sensing, and 0 (or 1) is used to indicate that resource 1 is not available for sensing. In this way, when 1 (or 0) is used to indicate that resource 1 is available for sensing, it means that resource 1 is not only used for communication but also for sensing, that is, it can be determined that at least part of resource 1 is used for sensing and communication, that is, at least part of resource 1 is a communication sensing resource. In this case, there are two possible situations for resource 1, resource 1 includes only communication resources and communication sensing resources, or resource 1 includes communication sensing resources. When 0 (or 1) is used to indicate that resource 1 is not available for sensing, it can be determined that resource 1 is only used for communication. In this case, resource 1 includes only communication resources.

[0408] In another example, in an embodiment where the scheduling information schedules a sensing resource, for resource 1 currently scheduled by the scheduling information, 1 (or 0) is used to indicate that resource 1 can be used for communication, and 0 (or 1) is used to indicate that resource 1 cannot be used for communication. In this way, when 1 (or 0) is used to indicate that resource 1 can be used for communication, it means that resource 1 is not only used for sensing, but also for communication, that is, at least part of the resources of resource 1 are used for sensing and communication, that is, at least part of the resources of resource 1 are communication sensing resources. In this case, there are two possible situations for resource 1, resource 1 includes sensing-only resources and communication sensing resources, or resource 1 includes communication sensing resources. When 0 (or 1) is used to indicate that resource 1 cannot be used for communication, it can be determined that resource 1 is only used for sensing. In this case, resource 1 includes sensing-only resources.

[0409] When determining that at least part of the resources of resource 1 are used for perception and communication based on the purpose information, in some embodiments, the granularity of the resources associated with the purpose information may be the entire resource (i.e., resource 1) scheduled by the scheduling information. For example, the 2-bit value in the purpose information indicates that it is used for perception and communication. The resource associated with the purpose information is resource 1, and is not specifically associated with the specific location of the communication perception resource used for perception and communication in resource 1. The first device can know that at least part of the resources of resource 1 are used for perception and communication based on the purpose information, but is unclear about the specific location of the communication perception resource used for perception and communication in resource 1. In this way, when the first device knows that at least part of the resources of resource 1 are used for perception and communication based on the purpose information, it can also determine the specific location of the communication perception resource in resource 1 based on other resources scheduled by the network device. For example, the scheduling information schedules the perception resources, and the first device determines at least part of the resources of resource 1 for perception and communication based on the purpose information. It can also determine the resources that overlap with resource 1 based on other communication resources previously scheduled and resource 1 currently scheduled. The overlapping resources are the communication perception resources of resource 1, and the non-overlapping resources are the perception-only resources of resource 1. If the overlapping resources are all the resources of resource 1, it means that all the resources of resource 1 are communication perception resources. For another example, the scheduling information schedules the communication resources, and the first device determines at least part of the resources of resource 1 for perception and communication based on the purpose information. It can also determine the resources that overlap with resource 1 based on other perception resources previously scheduled and resource 1 currently scheduled. The overlapping resources are the communication perception resources of resource 1, and the non-overlapping resources are the communication-only resources of resource 1. If the overlapping resources are all the resources of resource 1, it means that all the resources of resource 1 are communication perception resources. It should be understood that the overlapping resources described here represent resources that overlap in the time domain, frequency domain, and spatial domain.

[0410] When at least part of the resources scheduled by the scheduling information based on the above-mentioned purpose information is used for perception and communication, since the granularity of the resources associated with the purpose information is the entire resource scheduled by the scheduling information (i.e., resource 1), there is no need to indicate the specific location of the communication perception resources, which can effectively reduce the design complexity of the scheduling information and facilitate implementation.

[0411] In other embodiments, the granularity of the resources associated with the purpose information may be the communication-aware resources in the scheduled resource 1, so that the first device may clearly or accurately know which resources in the resource 1 are communication-aware resources based on the purpose information.

[0412] In the above embodiment, the purpose information in the scheduling information indicates the function of resource 1, so that the first device can know how to use resource 1, and the implementation complexity is low, and only one field needs to be added to the scheduling information to indicate the purpose information.

[0413] Method B

[0414] In mode B, different radio network temporary identities (RNTIs) may be used to correspond to different functions of resources, so that different functions of resource 1 may be determined according to different RNTIs. RNTI is used to scramble downlink control information (DCI).

[0415] In one example, sensing corresponds to RNTI1, communication corresponds to RNTI2, and sensing and communication correspond to RNTI3.

[0416] In this way, the first device can determine whether the resources scheduled by the scheduling information are used only for sensing, only for communication, or at least part of the resources are used for sensing and communication based on the RNTI of the DCI carrying the scheduling information. For ease of description, the DCI carrying the scheduling information for indicating resource 1 is recorded as DCI1.

[0417] When the RNTI of DCI1 carrying scheduling information is RNTI1, the first device may determine that the currently scheduled resource 1 is only used for perception and is a perception-only resource.

[0418] When the RNTI of the DCI1 carrying the scheduling information is RNTI2, the first device may determine that the currently scheduled resource 1 is only used for communication and is a communication-only resource.

[0419] When the RNTI of DCI1 carrying scheduling information is RNTI3, the first device can determine that at least part of the resources of the currently scheduled resource 1 are used for communication and perception, and resource 1 includes communication perception resources. In implementation, regardless of whether part or all of the resources of resource 1 are used for perception and communication, RNTI3 is used to scramble DCI, and the first device determines that at least part of the resources of the currently scheduled resource 1 are used for perception and communication based on RNTI3, and can further determine the specific location of the communication perception resources in resource 1 based on other resources scheduled by the network device. For example, the scheduling information schedules perception resources, and the first device determines that at least part of the resources of resource 1 are used for perception and communication based on RNTI3. It can also determine the resources that overlap with resource 1 based on other previously scheduled communication resources and currently scheduled resource 1. The overlapping resources are the communication perception resources of resource 1, and the non-overlapping resources are the perception-only resources of resource 1. If the overlapping resources are all the resources of resource 1, it means that all the resources of resource 1 are communication perception resources. For another example, the scheduling information schedules communication resources. The first device determines, based on RNTI3, that at least part of resource 1 is used for perception and communication. It can also determine, based on other perception resources previously scheduled and currently scheduled resource 1, the resources that overlap with resource 1. The overlapping resources are the communication perception resources of resource 1, and the non-overlapping resources are the communication-only resources of resource 1. If the overlapping resources are all resources of resource 1, it means that all resources of resource 1 are communication perception resources.

[0420] In the above embodiment, the function of resource 1 scheduled by the scheduling information is indicated by using the RNTI of the DCI carrying the scheduling information. Since no additional information or fields are needed, the signaling overhead can be reduced.

[0421] In some embodiments, the scheduling information may also include priority information; and, when at least part of the resources of resource 1 overlap with other resources in the time domain and frequency domain, the priority information is used to indicate that at least part of the resources preferentially carry communication signals or preferentially carry perception signals, wherein resource 1 is a perception resource and the other resources are communication resources, or resource 1 is a communication resource and the other resources are perception resources.

[0422] Exemplarily, 1 (or 0) is used to indicate that communication signals are carried preferentially, and 0 (or 1) is used to indicate that perception signals are carried preferentially.

[0423] It should be understood that the priority information here is for when at least part of the currently scheduled resources overlap (or conflict) with other resources in the time domain and frequency domain, it is necessary to consider giving priority to carrying communication signals or perception signals on the resources overlapping in the time domain and frequency domain. It should also be understood that at least part of the resources overlapping with other resources in the time domain and frequency domain are resources that cannot be reused, that is, the at least part of the resources are not communication perception resources, but only perception resources or only communication resources.

[0424] Take the case where the scheduling information schedules resources for sensing as an example, that is, resource 1 is a sensing resource. In one case, resource 1 includes sensing-only resources and communication sensing resources. The first part of resources of resource 1 is sensing-only resources, and the second part of resources is communication sensing resources. When the first part of resources (part of resources of resource 1) overlaps with communication resources in the time domain and frequency domain, the priority information specifically indicates that the first part of resources preferentially carries communication signals or sensing signals. When the priority information indicates that communication signals are preferentially carried, sensing is not performed on the first part of resources temporarily. When the priority information indicates that sensing signals are preferentially carried, the first part of resources is used for sensing. In another case, resource 1 includes sensing-only resources, and all resources of resource 1 are sensing-only resources. When resource 1 (all resources of resource 1) overlaps with communication resources in the time domain and frequency domain, the priority information specifically indicates that resource 1 preferentially carries communication signals or sensing signals. When the priority information indicates that communication signals are preferentially carried, sensing is not performed on resource 1 temporarily. When the priority information indicates that sensing signals are preferentially carried, resource 1 is used for sensing.

[0425] In a wireless system, if the first network device dynamically configures the first device, it will lead to large network overhead, waste network resources, and increase the overall implementation complexity. Therefore, in order to reduce signaling overhead and waste of resources, and minimize resource scheduling signaling for the first device, in some embodiments, when the resource 1 scheduled by the scheduling information includes communication perception resources, other resources for communication and perception can also be determined through the scheduling information.

[0426] In one example, the scheduling information includes channel indication information for indicating at least one communication channel that can be used for sensing, wherein the at least one communication channel has the same beamforming as the communication channel of the communication sensing resource of resource 1 (recorded as communication channel 1). In this way, based on the channel indication information, at least one communication channel can be determined, and the at least one communication channel can be used for sensing.

[0427] Beamforming is a signal processing technology that uses a sensor array to send and receive signals in a directional manner. It adjusts the parameters of the basic units of the phase array so that signals at certain angles obtain constructive interference, while signals at other angles obtain destructive interference, thereby achieving beam focusing, deflection, and shape control. Beamforming includes digital beamforming and analog beamforming. Digital beamforming is a beamforming technology implemented in the digital baseband processing stage. It processes antenna weights in the baseband module and has high precision and flexibility. It forms a beam pointing in a specific direction by adjusting the phase and amplitude of the signal transmitted or received by each antenna in the digital domain. Among them, digital beamforming includes a precoding codebook. Analog beamforming is a beamforming technology implemented in the analog baseband processing stage. By processing the RF signal weights, the antenna phase is adjusted through a phase shifter. Among them, analog beamforming includes a spatial domain filter.

[0428] In an embodiment of the present application, the communication channel 1 of the communication perception resource of resource 1 has the same beamforming as the at least one communication channel, which means that the two have the same digital beamforming and analog beamforming, and more specifically, the two have the same precoding codebook and spatial domain filter. It can be understood that the characteristics of communication channels with the same beamforming are relatively close or similar. Therefore, when resource 1 includes a communication perception resource, a communication channel with the same beamforming as the communication channel 1 of the communication perception resource of resource 1 may also be used for perception. Therefore, the above-mentioned communication channel that can be used for perception is indicated by channel indication information.

[0429] For analog beamforming, exemplarily, the first network device may use a spatial relationship or a quasi-co-location (QCL) relationship to determine a communication channel having the same analog beamforming as communication channel 1. In implementation, when there is a communication channel that has a spatial relationship or a quasi-co-location relationship with communication channel 1, it can be determined that the communication channel has the same analog beamforming (i.e., spatial filter) as communication channel 1. The spatial relationship indicates that one signal has the same spatial filter as another signal, and also indicates that a channel carrying one signal has the same spatial filter (i.e., analog beamforming) as a channel carrying another signal. The quasi-co-location relationship indicates that two or more antenna ports (or signal sources) have certain common attributes in the characteristics of the wireless channel. These attributes are called large-scale channel attributes. If two antenna ports are similar or identical in these large-scale channel attributes, the two antenna ports are considered to have a quasi-co-location relationship. The types of quasi-co-location relationships defined in 3Gpp include: QCL-TypeA, QCL-TypeB, QCL-TypeC, and QCL-TypeD, each type corresponding to a different combination of large-scale channel attributes. In implementation, if the wireless channel properties of one antenna port can be inferred from the wireless channel properties of another antenna port, the two antenna ports have a quasi-co-location relationship. Then, the wireless channels of the two antenna ports have a quasi-co-location relationship, and the quasi-co-location relationship of the two wireless channels can include at least one of four types (such as QCL-TypeD, or a combination of QCL-TypeD and QCL-TypeA).

[0430] For digital beamforming, the first network device may explicitly indicate the precoding codebook used by the first device. The first device may also determine the precoding codebook to be used by measuring a downlink reference signal. The first device may determine that different channels have the same digital beamforming according to the indication of the first network device or according to the precoding codebook used by itself.

[0431] When the first network device determines that each communication channel of the at least one communication channel has the same analog beamforming and digital beamforming as communication channel 1, it can be considered that each communication channel of the at least one communication channel has the same beamforming as communication channel 1, and then, the at least one communication channel is indicated by channel indication information.

[0432] In the channel indication information, the at least one communication channel may be indicated in the following manner.

[0433] In one example, the at least one communication channel is indicated in the form of a bitmap. One bit position corresponds to one channel, and a specific value (1 or 0) specified at the bit position indicates that the communication channel is available for sensing.

[0434] For example, the content of whether the communication channel is available for perception expressed in bitmap form is as follows: 01100000, corresponding to physical uplink control channel (PUCCH), physical downlink control channel (PDCCH), physical downlink shared channel (PDSCH), physical sidelink broadcast channel (PSBCH), physical sidelink shared channel (PSSCH), physical sidelink control channel (PSCCH), physical sidelink feedback channel (PSFCH), and physical broadcast channel (PBCH). When the value of the specified bit position is 1, it means that the communication channel can be used for perception. Therefore, the values ​​of the second bit position and the third bit position are 1, indicating that the communication channels corresponding to the second bit position and the third bit position are available for perception. Among them, the PDCCH corresponding to the second bit position is the communication channel of the communication perception resource in resource 1 scheduled by the scheduling information, and the PDSCH corresponding to the third bit position is the communication channel with the same beamforming as the PDCCH.

[0435] In another example, a communication channel (communication channel 1) of a communication sensing resource of resource 1 scheduled by relationship information and scheduling information is used to determine a communication channel having the same analog beamforming as communication channel 1. The relationship information is used to indicate a quasi-co-location relationship 1 or a spatial relationship 1, and the relationship information can be carried in the scheduling information or in other information (such as RRC signaling). For example, the relationship information is carried in a DCI (denoted as DCI2) carried on communication channel 1, and DCI1 is used to schedule a new communication channel (denoted as communication channel 2). When communication channel 2 and communication channel 1 satisfy the quasi-co-location relationship 1 or the spatial relationship 1 indicated in the relationship information, communication channel 2 can be considered to have the same analog beamforming as communication channel 1.

[0436] For digital beamforming, the first device may determine whether the digital beamforming of the new communication channel is the same as that of the communication channel 1 based on the digital beamforming respectively adopted by the communication channel 2 and the communication channel 1 .

[0437] When the first device determines that the communication channel 2 has the same analog beamforming and digital beamforming as the communication channel 1, it can be considered that the communication channel 2 has the same beamforming as the communication channel 1, and therefore, it can be determined that the communication channel 2 can be used for sensing. In this way, at least one communication channel having the same beamforming as the communication channel 1 can be determined in the above manner, and the at least one communication channel can be used for sensing.

[0438] In another example, the scheduling information includes determination information indicating that the signal quality of the communication signal transmitted on the communication channel is greater than or equal to the quality threshold.

[0439] When the first device subsequently receives a communication signal on the communication channel, if the signal quality of the communication signal is greater than or equal to the quality threshold, it can be determined that the corresponding communication channel can be used for sensing.

[0440] Here, the quality threshold can be determined by the modulation and coding scheme (MCS) of the communication channel (communication channel 1) of the communication sensing resource based on resource 1. Taking SNR as an example to represent signal quality, communication channel 1 is PDSCH, and the minimum value of the SNR of PDSCH can be used as the quality threshold, and the SNR corresponds to a specific MCS. In implementation, different MCSs correspond to different minimum values ​​of SNR, and the offset values ​​of SNR corresponding to different MCSs can be determined by looking up the table, thereby determining the minimum values ​​of SNR corresponding to different MCSs. For example, the minimum value of SNR corresponding to the MCS with an index of 1 is A. If the MCS of PDSCH is indexed as 4, the corresponding minimum value of SNR = A + △1. If the MCS of PDSCH is indexed as 8, the corresponding minimum value of SNR = A + △2, where △1 and △2 are increments.

[0441] In another example, the scheduling information also includes beam information of a received communication beam that can be used to sense, including beam ID, beam direction, beam width, and the like.

[0442] In implementation, the channel indication information, relationship information, judgment information and beam information of the above four examples can be used in combination or independently. The perceptible receiving communication beam is determined by beam information, and at least one communication channel that can be used for perception can be determined by channel indication information or relationship information. Based on the judgment information, a communication channel that meets the quality threshold can be determined from the at least one communication channel. If there are multiple communication channels that meet the quality threshold, the communication channel with the best quality threshold can be selected as the final perceptible communication channel, thereby determining the communication channel and communication beam of the communication resources that can be used for perception. In the embodiment where the above resource 1 includes communication perception resources, the first device performs perception based on the communication signal transmitted on the communication perception resources, and the type of the first device in different scenarios and the device that cooperates with the first device for perception are different.

[0443] For scenarios where the first network device and the first device perform perception, such as scenario 1 and scenario 2 above, in step S160, the first network device and the first device perform perception based on the communication signal transmitted on the communication perception resource. In scenario 1, the first device is a first terminal device, and in scenario 2, the first device is a second network device.

[0444] In the above scenario 3, the first terminal device (an example of the first device) and the second terminal device perform perception based on the communication signal transmitted on the communication perception resource.

[0445] In the above scenario 4, the first terminal device (an example of the first device) transmits and receives autonomously, and performs perception based on the communication signal transmitted on the communication perception resource.

[0446] In the embodiment provided by the above method 100, the first device as a measurement node measures the link (i.e., the communication link, such as link 1) that currently transmits the communication signal based on the multiplexing measurement condition. The multiplexing measurement condition is used to determine the communication link that can be used for perception, so that the first network device can determine whether the link is used for perception based on the measurement report obtained by measuring the link. Then, the first network device can comprehensively consider the scheduling of communication and perception resources based on whether the link is used for perception, and indicate the resources (such as resource 1) scheduled for the first device through the scheduling information sent to the first device. The scheduled resources include at least one of only perception resources, only communication resources, and communication perception resources. In this way, when the scheduled resources include communication perception resources, since perception can be performed based on the communication signal transmitted on the communication perception resources, no additional perception resources are required, and the occupation of perception resources is reduced, so that the resource utilization rate can be effectively improved; when the scheduled resources include only perception resources or only communication resources, the normal progress of communication and perception can be maintained as much as possible, and the interference between communication and perception can be reduced. Therefore, the embodiment of the present application measures the link (i.e., the communication link) that currently transmits the communication signal based on the multiplexing measurement conditions to determine whether the communication resources of the link are used for the perception scheme, which can provide a multiplexing basis for the scheduling of communication and perception resources, and improve the resource utilization as much as possible while maintaining the normal communication and perception as much as possible, so as to maximize the use of wireless resources and thus improve system performance.

[0447] The above, from step S110 to step S150, describes in detail the method 100 for integrating synaesthesia in the embodiment of the present application. It should be understood that the above process is only for illustrative purposes and should not be construed as limiting the embodiment of the present application.

[0448] In the above method, when link 1 does not meet the first type of condition, the first device does not send a measurement report. In other embodiments, regardless of the situation in which the first device measures link 1, the first device sends a measurement report. Fig.13 In the illustrated cases 2 and 3, link 1 is not available for perception. Therefore, in cases 2 and 3, the measurement report includes not only multiplexing indication information indicating that it is not available for perception, but in some embodiments, the measurement report also includes measurement results, so that the first network device can distinguish whether link 1 is not available for perception corresponding to case 2 or case 3, so as to determine different scheduling strategies; in other embodiments, the measurement report may also include indication information (recorded as indication information 1) indicating whether link 1 satisfies the first type of condition, so that the first network device can distinguish whether link 1 is not available for perception corresponding to case 2 or case 3, so as to determine different scheduling strategies.

[0449] When measuring link 1, Fig.13In the case 1 shown, in step S1311, the first device sends a measurement report, and the measurement report includes multiplexing indication information, such as ACK information, for indicating that link 1 can be used for perception. In step S141, the first network device determines whether link 1 meets the perception requirement based on the received measurement report. In the case where link 1 meets the perception requirement based on step S141 (case 1.1), in step S1421, the first network device determines that the scheduling strategy for the resources of link 1 is scheduling strategy 1. In the case where link 1 does not meet the perception requirement based on step S141 (case 1.2), in step S1422, the first network device determines that the scheduling strategy for the resources of link 1 is scheduling strategy 2.

[0450] When measuring link 1, Fig.13 In case 2 shown, in step S1312, the first device sends a measurement report, and the measurement report includes multiplexing indication information, such as NACK information, indicating that link 1 is not available for sensing. In some embodiments, the measurement report also includes the measurement result of link 1. In one example, the measurement result of link 1 includes the results corresponding to each condition obtained by measuring each condition of the first type of condition and the second type of condition, and the result corresponding to each condition may include a measurement value. Exemplarily, the result corresponding to each condition also includes indication information indicating whether link 1 satisfies the condition. In another example, the measurement result includes indication information indicating at least one condition satisfied by link 1, and may also include measurement values ​​corresponding to each condition in the at least one condition. In this way, after receiving the measurement report, the first network device can determine that link 1 is not available for sensing based on the multiplexing indication information, and further combined with the measurement result, it can be determined that link 1 satisfies the first type of condition but does not satisfy the second type of condition, that is, it is determined that the channel condition of link 1 does not satisfy the condition. Therefore, in step S1422, the first network device determines that the scheduling strategy of the resources of link 1 is scheduling strategy 2. In other embodiments, the measurement report also includes indication information 1 for indicating whether link 1 satisfies the first type of conditions. In this way, after receiving the measurement report, the first network device can determine that link 1 is not available for perception based on the multiplexing indication information. Based on the indication information 1, it can be determined that link 1 only satisfies the first type of conditions. Therefore, in step S1422, the first network device determines that the scheduling strategy for the resources of link 1 is scheduling strategy 2.

[0451] When measuring link 1, Fig.13In case 3 shown, the first device will also send a measurement report, and the measurement report includes multiplexing indication information, such as NACK information, indicating that link 1 is not available for perception. In some embodiments, the measurement report also includes the measurement result of link 1. In one example, the measurement result of link 1 includes the results corresponding to each condition obtained by measuring each condition of the first type of conditions, and the result corresponding to each condition may include a measurement value. Exemplarily, the result corresponding to each condition also includes indication information indicating whether link 1 satisfies the condition. In another example, the measurement result includes indication information indicating at least one condition satisfied by link 1, and may also include measurement values ​​corresponding to each condition in the at least one condition. In this way, after receiving the measurement report, the first network device can determine that link 1 is not available for perception based on the multiplexing indication information, and further combined with the measurement result, it can be determined that link 1 does not meet the first type of conditions. Therefore, in step S1423, the first network device determines that the scheduling strategy for the resources of link 1 is scheduling strategy 3. In other embodiments, the measurement report also includes indication information 1 for indicating whether link 1 satisfies the first type of condition. In this way, after receiving the measurement report, the first network device can determine that link 1 is not available for perception based on the multiplexing indication information. Based on the indication information 1, it can be determined that link 1 does not satisfy the first type of condition. Therefore, in step S1423, the first network device determines that the scheduling strategy for the resources of link 1 is scheduling strategy 3.

[0452] Fig.14 It is another schematic flowchart of a process of performing link measurement based on multiplexing measurement conditions to determine whether a communication link is available for perception provided by an embodiment of the present application.

[0453] Fig.14 The process mainly involves the process of step S131 and step S140 of method 100. Fig.14 and Fig.13 The main difference is that in Fig.14 In the multiplexing measurement conditions, not only the first type of conditions and the second type of conditions are included, but also the perception requirements are included. Thus, in step 120, the process of the first device measuring link 1 includes not only the process of measuring link 1 based on the first type of conditions and the second type of conditions, but also the process of measuring link 2 based on the perception requirements to determine whether link 1 meets the perception requirements. In other words, the determination of whether link 1 meets the perception requirements is performed by the first device. Based on this, there are also differences between the behavior of the first device generating and sending the measurement report and the behavior of the first network device determining the scheduling strategy. In the following, the focus is on Fig.14 and Fig.13 The differences between the two are emphasized and the similarities are briefly described.

[0454] The first device receives measurement indication information, where the multiplexing measurement conditions indicated by the measurement indication information may include first-type conditions, second-type conditions, and perception requirements, and measures link 1 based on the first-type conditions, second-type conditions, and perception requirements.

[0455] In step S131a, the first device determines whether link 1 satisfies the first type of condition.

[0456] When link 1 does not meet the first type of condition (recorded as case A3), the first device does not send a measurement report.

[0457] In case A3, correspondingly, the first network device does not receive the measurement report. In the absence of special circumstances, it can be determined that link 1 is not available for sensing. More specifically, it can be determined that link 1 does not meet the first type of conditions, that is, the spatial resources of link 1 are not available for sensing. Thus, in step S1433, the first network device determines that the scheduling strategy for the resources of link 1 is scheduling strategy 3.

[0458] The situation A3 here and the scheduling strategy 3 corresponding to the situation A3 are the same as the situation 3 and the scheduling strategy 3 corresponding to the situation 3 above, and will not be repeated here.

[0459] When link 1 meets the first type of condition, the first device executes step S131b.

[0460] In step S131b, when link 1 satisfies the first type of condition, the first device determines whether link 1 satisfies the second type of condition.

[0461] In the case where link 1 does not meet the second type of condition (recorded as case A2), it means that the spatial resources of link 1 can be used for sensing, but the channel condition of the communication channel does not meet the condition, and the first device determines that link 1 is not available for sensing. Therefore, in step S1315, the first device sends a measurement report to the first network device, and correspondingly, the first network device receives the measurement report. The measurement report includes multiplexing indication information for indicating that link 1 is not available for sensing, such as NACK information.

[0462] In case A2, the first network device can determine that link 1 is not available for sensing based on the multiplexing indication information in the received measurement report, and more specifically, it can be determined that link 1 meets the first type of condition and does not meet the second type of condition, that is, it is determined that the channel condition of the communication channel of link 1 does not meet the condition. In this way, in step S1432, the first network device determines that the scheduling strategy for the resources of link 1 is scheduling strategy 2.

[0463] The situation A2 here and the scheduling strategy 2 corresponding to the situation A2 are the same as the situation 2 and the scheduling strategy 2 corresponding to the situation 2 above, and will not be repeated here.

[0464] When link 1 meets the second type of condition, the first device executes step S131c.

[0465] In step S131c, when link 1 meets the second type of condition, the first device determines whether link 1 meets the perception requirement.

[0466] Exemplarily, the first device determines whether link 1 meets the sensing requirement according to the sensing assistance information obtained by measurement. For the specific description of the sensing assistance information and the sensing requirement, reference may be made to the above related description, which will not be repeated here.

[0467] In the case where link 1 meets the perception requirement (recorded as case A1-1), in step S1314, the first device sends a measurement report, and the measurement report includes multiplexing indication information, such as ACK information, for indicating that link 1 is perceptible. Correspondingly, based on the received measurement report, the first network device can be sure that link 1 can be used for perception. Therefore, in step S1431, the first network device determines that the scheduling strategy for the resources of link 1 is scheduling strategy 1. For the specific description of scheduling strategy 1, please refer to the relevant description above, which will not be repeated.

[0468] In the case where link 1 does not meet the perception requirement (recorded as case A1-2), in step S1315, the first device sends a measurement report to the first network device, and the measurement report includes multiplexing indication information, such as NACK information, for indicating that link 1 is not perceptible. Correspondingly, based on the received measurement report, the first network device can be sure that link 1 is not available for perception, so in step S1432, the first network device determines that the scheduling strategy for the resources of link 1 is scheduling strategy 2.

[0469] Will Fig.14 and Fig. 9 Combined, Fig. 9 Step S131 includes Fig.14 Step S1315 or step S1314, Fig. 9 Step S140 includes Fig.14 The logical relationship between the steps shall be based on their internal logical relationship.

[0470] Fig.15 It is a schematic flow chart of the method 200 for synaesthesia integration provided in an embodiment of the present application.

[0471] The main difference from the above method 100 is that in method 200, the first network device is the receiving end of the signal in the link measurement, and as the measurement node of the link measurement, the first device is the sending end of the signal in the link measurement. The following focuses on the differences between method 200 and method 100, and briefly describes the similarities between the two.

[0472] In method 100, the first network device interacts with the first device, and the first network device, as a measuring node, measures the communication link (referred to as link 2) currently used to transmit communication signals to determine whether link 2 can be used for perception, and the first network device comprehensively considers the allocation of communication resources and perception resources based on the measurement of link 2. Compared with method 100, in method 200, since the measuring node does not need to feedback the measurement report of the link measurement, the signaling overhead is reduced to a certain extent, and for the scenario of measuring the link between the network device and the terminal device, since the terminal device does not need to perform link measurement, the power consumption of the terminal device can be effectively reduced.

[0473] The method 200 of the embodiment of the present application may correspond to multiple scenarios, and the first device and the link 2 in different scenarios are interpreted differently.

[0474] Scene 5

[0475] Link 2 is a communication link between a first network device and a first terminal device, wherein the first device is a first terminal device.

[0476] Please refer to Figure 1 Figure (b) and Figure 4 In (b), link 2 is communication link A2, which is a link between network device A (an example of the first network device) and terminal device A (an example of the first terminal device), terminal device A is a communication node that sends communication signals, network device A is a communication node that receives communication signals, and network device A serves as a measurement node for link measurement, and network device A comprehensively considers the allocation of communication resources and perception resources based on the measurement of communication link A2.

Figure 4 In an example in Figure (b), network device A or terminal device A is the sensing target.

[0477] Scene 6

[0478] Link 2 is a communication link between a first network device and a second network device, wherein the first device is the second network device.

[0479] Please refer to Figure 2 Figure (b) and Figure 5In (b) of the figure, link 2 is communication link A2, which is a link between network device A (an example of the first network device) and network device B (an example of the second network device), network device B is a communication node that sends communication signals, network device A is a communication node that receives communication signals, and network device A serves as a measurement node for link measurement, and network device A comprehensively considers the allocation of communication resources and perception resources based on the measurement of communication link A12. Figure 2 In an example of Figure (b) in Figure 1, the scatterer on communication link A2 is the sensing target. Figure 5 In an example of Figure (b), network device A or network device B is the sensing target.

[0480] In step S220 , the first network device measures link 2 (communication link).

[0481] In step S230 , the first network device determines a scheduling strategy for resources of link 2 (communication link).

[0482] In the above steps, the first network device measures link 2 based on the multiplexing measurement condition to obtain a measurement result, and then determines a scheduling strategy for resources of link 2 based on the measurement result.

[0483] In some embodiments, the measurement results include results corresponding to each condition obtained by measuring each condition, and the result corresponding to each condition may include a measurement value. Exemplarily, the result corresponding to each condition also includes indication information for indicating whether link 2 meets the condition.

[0484] The first network device is configured with a multiplexing measurement condition, or other devices (such as core network elements) send information indicating the information multiplexing measurement condition to the first network device, so that the first network device obtains the multiplexing measurement condition.

[0485] In some embodiments, the multiplexing measurement conditions include a first type of conditions for determining a communication link capable of providing the sensing information.

[0486] Exemplarily, the first type of conditions includes at least one condition: a first condition, a second condition, a third condition, and a fourth condition.

[0487] In another embodiment, the multiplexing measurement conditions include not only the first type of conditions but also the second type of conditions, where the second type of conditions are related to the communication signal.

[0488] Exemplarily, the second category of conditions includes at least one condition: a fifth condition, a sixth condition, a seventh condition, an eighth condition, and a ninth condition.

[0489] In some other embodiments, the multiplexed measurement conditions include not only the first type of conditions and the second type of conditions, but also perception requirements.

[0490] The main indicators of perception requirements include but are not limited to unambiguous range, resolution, measurement accuracy and other indicators.

[0491] Exemplarily, the perception requirement includes at least one of the following: the perceived unambiguous range is within a preset range; the perceived resolution is greater than or equal to a resolution threshold; the perceived measurement accuracy is greater than or equal to a measurement accuracy threshold; and the channel change rate meets the requirements.

[0492] For the specific description of the first type of conditions, the second type of conditions, and the perception needs, please refer to the relevant description above. For the specific description of the first network device measuring link 2 based on the first type of conditions, the second type of conditions, and the perception needs, please refer to the above description of the first device measuring link 1 based on the first type of conditions and the second type of conditions and the first network device measuring link 2 based on perception needs. We will not go into details here and just replace link 1 above with link 2 here.

[0493] In some embodiments, in step S210 before step S220, the first device may send measurement assistance information to the first network device to assist the first network device in performing link measurement. The measurement assistance information includes at least one of the following information.

[0494] The location information of the first device is used to indicate the location of the first device.

[0495] The information of the transmitted communication beam on link 2 indicates the communication beam through which the first device transmits the communication signal on link 2. Exemplarily, the information of the transmitted communication beam on link 2 may include a beam identifier (such as a beam ID), a beam width, and a beam direction.

[0496] The above-mentioned measurement auxiliary information can be used in combination with the first condition and the second condition of the multiplexed measurement conditions. For example, the location information of the first device can be used in combination with the first condition and the second condition, and the information of the transmitted communication beam on link 2 can be used in combination with the second condition. For specific descriptions, please refer to the relevant descriptions of the process of performing link measurement based on the first condition and the second condition above, which will not be repeated here.

[0497] Next, taking the multiplexing measurement conditions including the first type of conditions, the second type of conditions and the perception requirements as an example, combined with the situation where the first network device measures link 2 based on the multiplexing measurement conditions, step S220 and step S230 are specifically described.

[0498] Fig.16It is another schematic flowchart of a process of performing link measurement based on multiplexing measurement conditions to determine whether a communication link is available for perception provided by an embodiment of the present application.

[0499] In an embodiment where the multiplexing measurement conditions include the first type of conditions, the second type of conditions, and the perception requirements, the first network device measures link 2 based on the multiplexing measurement conditions, and there are four situations (case B1-1, case B1-2, case B2, and case B4 below). The scheduling strategy determined by the first network device is different based on different situations.

[0500] Case B1-1 and the scheduling strategy for case B1-1

[0501] In case B1-1, based on the measurement results of link 2 (communication link), it is determined that link 2 meets the first type of conditions, the second type of conditions and the perception requirements. In this way, the first network device determines that link 2 can be used for perception, and therefore determines that the scheduling strategy of link 2 is scheduling strategy 2.

[0502] refer to Fig.16 Exemplarily, in step S230a, based on the measurement result, the first network device determines whether link 2 satisfies the first type of condition. When link 2 satisfies the first type of condition, in step S30b, the first network device determines whether link 2 satisfies the second type of condition. When link 2 satisfies the second type of condition, in step S230c, the first network device determines whether link 2 meets the perception requirement. When link 2 meets the perception requirement, the first network device determines that link 2 meets the first type of condition, the second type of condition and the perception requirement, which means that link 2 can be used for perception. Therefore, in step S2311, the first network device determines that the scheduling strategy for the resources of link 2 is scheduling strategy 1.

[0503] It should be noted that situation B1-1 of method 200 is the same as situation 1.1 of method 100 above. The measured communication links all meet the first type of conditions, the second type of conditions and the perception requirements. Correspondingly, the scheduling strategy 1 corresponding to situation B1-1 is the same as the scheduling strategy 1 corresponding to situation 1.1 above. For the specific description of situation B1-1 and the scheduling strategy 1 corresponding to situation B1-1, please refer to the relevant description above and will not be repeated here.

[0504] Case B1-2 and the scheduling strategy for case B1-2

[0505] In case B1-2, based on the measurement results of link 2 (communication link), it is determined that link 2 meets the first and second conditions, but does not meet the perception requirements, which means that the perception results obtained by using the communication resources of link 2 to perceive the perception target do not meet the requirements. Therefore, the first network device determines that link 2 cannot be used for perception, and determines that the scheduling strategy of link 2 is scheduling strategy 2.

[0506] refer to Fig.16 Exemplarily, in step S230a, based on the measurement result, the first network device determines whether link 2 satisfies the first type of condition. When link 2 satisfies the first type of condition, in step S230b, the first network device determines whether link 2 satisfies the second type of condition. When link 2 satisfies the second type of condition, in step S230c, the first network device determines whether link 2 meets the perception requirement. When link 2 does not meet the perception requirement, the first network device determines that link 2 meets the first type of condition and the second type of condition, but does not meet the perception requirement. Therefore, in step S2312, the first network device determines that the scheduling strategy for the resources of link 2 is scheduling strategy 2.

[0507] It should be noted that situation B1-2 of method 200 is the same as situation 1.2 of method 100 above. The measured communication link meets the first and second conditions but does not meet the perception requirements. Correspondingly, the scheduling strategy 2 corresponding to situation B1-2 is the same as the scheduling strategy 2 corresponding to situation 1.2 above. For the specific description of situation B1-2 and the scheduling strategy 2 corresponding to situation B1-2, please refer to the relevant description above and will not be repeated here.

[0508] Case B2 and the scheduling strategy for case B2

[0509] In case B2, based on the measurement results of link 2 (communication link), it is determined that link 2 meets the first type of conditions and does not meet the second type of conditions, which means that the spatial resources of link 2 can be used for perception, but the channel conditions of the communication channel do not meet the conditions. Therefore, the first network device determines that link 2 is not available for perception, and determines that the scheduling strategy for the resources of link 2 is scheduling strategy 2.

[0510] refer to Fig.16 Exemplarily, in step S230a, based on the measurement result, the first network device determines whether link 2 satisfies the first type of condition. When link 2 satisfies the first type of condition, in step S230b, the first network device determines whether link 2 satisfies the second type of condition. When link 2 does not satisfy the second type of condition, the first network device determines that link 2 satisfies the first type of condition and does not satisfy the second type of condition. Therefore, in step S2312, the first network device determines that the scheduling strategy for the resources of link 2 is scheduling strategy 2.

[0511] It should be noted that situation B2 of method 200 is the same as situation 2 of method 100 above. The measured communication link satisfies the first type of conditions but does not satisfy the second type of conditions. Correspondingly, the scheduling strategy 2 corresponding to situation B2 is the same as the scheduling strategy 2 corresponding to situation 2 above. For the specific description of situation B2 and the scheduling strategy 2 corresponding to situation B2, please refer to the relevant description above and will not be repeated here.

[0512] Case B3 and the scheduling strategy for case B3

[0513] In case B3, based on the measurement results of link 2 (communication link), it is determined that link 2 does not meet the first type of conditions, which means that the spatial resources of link 2 are not available for perception. Therefore, the first network device determines that link 2 is not available for perception, and determines that the scheduling strategy for the resources of link 2 is scheduling strategy 3.

[0514] refer to Fig.16 Exemplarily, in step S230a, based on the measurement results, the first network device determines whether link 2 satisfies the first type of conditions. When link 2 does not satisfy the first type of conditions, the first network device determines that link 2 is not available for perception. Therefore, in step S2313, the first network device determines that the scheduling strategy for the resources of link 2 is scheduling strategy 3.

[0515] It should be noted that situation B3 of method 200 is the same as situation 3 of method 100 above. The measured communication link does not meet the first type of conditions. Correspondingly, the scheduling strategy 3 corresponding to situation B3 is the same as the scheduling strategy 3 corresponding to situation 3 above. For the specific description of situation B3 and the scheduling strategy 3 corresponding to situation B3, please refer to the relevant description above and will not be repeated here.

[0516] In step S240, the first network device sends scheduling information.

[0517] In this step, the first network device determines and sends scheduling information based on the scheduling strategy of the communication resources of the determined link 2. The scheduling information indicates the scheduled resources (recorded as resource 2), and resource 2 includes at least one resource: perception-only resource, communication-only resource, and communication-perception resource.

[0518] Here, for the specific description of resource 2 and scheduling information, please refer to the relevant description of resource 1 and scheduling information in method 100, which will not be repeated here.

[0519] In the embodiment where the resource 2 includes a communication-aware resource, in step S250, the first network device and the first device perform perception based on a communication signal transmitted on the communication-aware resource.

[0520] In the embodiment provided by the above method 200, the first network device as a measurement node measures the link (i.e., the communication link, such as link 2) that currently transmits the communication signal based on the multiplexing measurement condition. The multiplexing measurement condition is used to determine the communication link that can be used for perception, so that the first network device can determine whether the link is used for perception based on the measurement result of the link. Then, the first network device can comprehensively consider the scheduling of communication and perception resources based on whether the link is used for perception, and indicate the resources (such as resource 2) scheduled for the first device through the scheduling information sent to the first device. The scheduled resources include at least one of only perception resources, only communication resources, and communication perception resources. In this way, when the scheduled resources include communication perception resources, since perception can be performed based on the communication signal transmitted on the communication perception resources, no additional perception resources are required, and the occupation of perception resources is reduced. Therefore, the resource utilization rate can be effectively improved; when the scheduled resources include only perception resources or only communication resources, the normal progress of communication and perception can be maintained as much as possible, and the interference between communication and perception can be reduced. Therefore, the embodiment of the present application measures the link (i.e., the communication link) that currently transmits the communication signal based on the multiplexing measurement conditions to determine whether the communication resources of the link are used for the perception scheme, which can provide a multiplexing basis for the scheduling of communication and perception resources, and improve the resource utilization as much as possible while maintaining the normal communication and perception as much as possible, so as to maximize the use of wireless resources and thus improve system performance.

[0521] Furthermore, since the measurement node does not need to feed back the measurement results of the link measurement, the signaling overhead is reduced to a certain extent. In the scenario where the link between the network device and the terminal device is measured, since the terminal device does not need to perform link measurement, the power consumption of the terminal device can be effectively reduced.

[0522] Fig.17 It is a schematic flow chart of the synaesthesia integration method 300 provided in an embodiment of the present application.

[0523] In method 300, the first network device and the first device are continued to be taken as examples to describe method 300 from the perspective of interaction between the first network device and the first device. The first network device interacts with the first device. As the first device of the measurement node, the first device measures the communication link (hereinafter referred to as the first link) currently used to transmit the communication signal based on the multiplexing measurement condition to determine whether the first link can be used for perception. The first network device comprehensively considers the scheduling of communication resources and perception resources based on the measurement situation of the first link.

[0524] Method 300 is analogous to method 100. Specifically, the first network device of method 300 is analogous to the first network device of method 100, the first device of method 300 is analogous to the first device of method 100, and the first link of method 300 is analogous to link 1 of method 100; the scenarios applicable to method 300 are the same as the scenarios applicable to method 100 (scenario 1 to scenario 4 described above), and correspondingly, the explanations of the first device and the first link in different scenarios are also the same as the first device and link 1 of method 100, so the specific description here can refer to the relevant description above and will not be repeated.

[0525] In step S301, a first device measures a first link based on a multiplexing measurement condition.

[0526] In some embodiments, the first network device sends measurement indication information to the first device, where the measurement indication information includes condition information for indicating the multiplexing measurement condition. Correspondingly, the first device receives the measurement indication information.

[0527] In some other embodiments, other devices (such as core network elements) send measurement indication information to the first device, and correspondingly, the first device receives the measurement indication information.

[0528] In some embodiments, when the first link is a communication link between the first network device and the first device, the measurement indication information further includes measurement assistance information, and the measurement assistance information includes at least one of the following:

[0529] location information of the first network device;

[0530] information of a second communication beam, where the second communication beam is a transmission communication beam on the first link;

[0531] Perceive target information;

[0532] Perceive the information of the area;

[0533] Information of a first perception beam, where the first perception beam is a perception beam for sending a perception signal by the first network device.

[0534] In this way, the first device can measure the first link based on the measurement assistance information and the multiplexing measurement condition to obtain a measurement report of the first link.

[0535] Regarding the multiplexing measurement condition, in some embodiments, the multiplexing measurement condition includes a first type of condition. Thus, the first device measures the first link based on the first type of condition. For a specific description, reference may be made to the relevant description of method 100.

[0536] In some other embodiments, the multiplexed measurement condition includes a first type of condition and a second type of condition. Thus, the first device measures the first link based on the first type of condition and the second type of condition. For a detailed description, please refer to method 100 and Fig.13 Related description.

[0537] In some other embodiments, the multiplexed measurement condition includes a first type of condition, a second type of condition, and a perception requirement. Thus, the first device measures the first link based on the first type of condition, the second type of condition, and the perception requirement. For a detailed description, please refer to method 100 and Fig.14 Related description.

[0538] For a detailed description of the first type of conditions, the second type of conditions and the perceived needs, please refer to the relevant description of method 100 above, which will not be repeated here.

[0539] In step S310, the first device sends a measurement report obtained by the first device measuring the first link based on the multiplexing measurement condition to the first network device.

[0540] The measurement report includes multiplexing indication information, and the multiplexing indication information is used to indicate whether the first link can be used for perception.

[0541] In step S320, the first network device determines first scheduling information according to the measurement report.

[0542] The first scheduling information is used to indicate a first resource, and the first resource includes at least one resource: a perception-only resource, a communication-only resource, and a communication-perception resource.

[0543] In this step, in some embodiments, the first network device determines a scheduling policy for resources of the first link based on the received measurement report, and determines the first scheduling information based on the scheduling policy for resources of the first link.

[0544] In some embodiments, the first device selectively sends a measurement report based on the measurement of the first link, and the specific content of the sent measurement report is different. Thus, the behavior of the first network device in determining the first scheduling information according to the measurement report is also different. Fig.13 and Fig.14 The illustrated embodiment is described.

[0545] In an embodiment where the multiplexed measurement condition includes a first type of condition and a second type of condition, reference Fig.13, when the first link satisfies the first type of conditions and the second type of conditions (i.e., situation 1), the first device sends a measurement report to the first network device, and the multiplexing indication information (such as ACK information) in the measurement report is used to indicate that the first link can be used for perception; when the first link satisfies the first type of conditions but does not satisfy the second type of conditions (i.e., situation 2), the first device sends a measurement report to the first network device, and the multiplexing indication information (such as NACK information) in the measurement report is used to indicate that the first link cannot be used for perception; when the first link does not satisfy the first type of conditions (i.e., situation 3), the first device does not send (or prohibits sending) the measurement report.

[0546] For detailed description of this method, please refer to Fig.13 The descriptions of the measurement reports under Case 1, Case 2 and Case 3 are not repeated here.

[0547] In the above situation 1, the measurement report sent by the first device includes not only the multiplexing indication information indicating that the first link is perceptible, but in some embodiments, the measurement report also includes perception assistance information to facilitate the first network device to further determine whether the first link can be used for perception. For a specific description of the perception assistance information, please refer to the relevant description above and will not be repeated.

[0548] In the above situation 1 and the embodiment in which the measurement report includes the perception assistance information, the first network device knows that the first link satisfies the first type of condition and the second type of condition based on the multiplexing indication information, and therefore determines the scheduling strategy of the resources of the first link according to the perception assistance information and the perception requirement. For the specific description of the perception requirement, please refer to the relevant description above, which will not be repeated here.

[0549] In one example, when it is determined according to the perception assistance information that the first link meets the perception requirement, the scheduling strategy of the resources of the first link is determined to be a first scheduling strategy, and the first scheduling strategy is used to indicate that the communication resources of the first link can be used for perception.

[0550] In another example, when it is determined based on the perception auxiliary information that the first link does not meet the perception requirements, the scheduling strategy for the resources of the first link is determined to be a second scheduling strategy, and the second scheduling strategy is used to indicate that the perception resources are orthogonal to the communication resources of the first link in the time domain and / or frequency domain.

[0551] In the above situation 2, the first network device determines that the first link is not available for perception based on the multiplexing indication signal. More specifically, it can be determined that the first link meets the first type of conditions but does not meet the second type of conditions. Therefore, the first network device determines that the scheduling strategy for the resources of the first link is the second scheduling strategy.

[0552] Here, the first scheduling strategy and the second scheduling strategy can be respectively analogous to scheduling strategy 1 and scheduling strategy 2 of method 100. The specific description of the first scheduling strategy and the second scheduling strategy can refer to the above description of scheduling strategy 1 and scheduling strategy 2, and will not be repeated here.

[0553] In an embodiment where the multiplexed measurement conditions include the first type of conditions, the second type of conditions, and the perception requirements, reference Fig.14 , when the first link meets the first type of conditions, the second type of conditions and the perception requirements (i.e., situation A1-1), the first device sends a measurement report to the first network device, and the multiplexing indication information (such as ACK) in the measurement report is used to indicate that the first link can be used for perception; when the first link meets the first type of conditions and the second type of conditions, but does not meet the perception requirements (i.e., situation A1-2), the first device sends a measurement report to the first network device, and the multiplexing indication information (such as NACK) in the measurement report is used to indicate that the first link cannot be used for perception; when it is determined that the first link meets the first type of conditions and does not meet the second type of conditions (i.e., situation A2), the first device sends a measurement report to the first network device, and the multiplexing indication information (such as NACK) in the measurement report is used to indicate that the first link cannot be used for perception; when the first link does not meet the first type of conditions (i.e., situation A3), the first device does not send (or prohibits sending) the measurement report.

[0554] For a detailed description of this, please refer to Fig.14 The relevant descriptions about the measurement report under Case A1-1, Case A1-2, Case A2, and Case A3 are not repeated here.

[0555] In the above situation A1-1, the first network device knows that the first link can be used for perception based on the multiplexing indication information. Specifically, it can be determined that the first link meets the first type of conditions, the second type of conditions and the perception requirements. Therefore, the first network device determines that the scheduling strategy for the resources of the first link is the first scheduling strategy.

[0556] In the above situation A1-2, the first network device is aware of the unavailability perception of the first link based on the multiplexing indication information, and therefore, the first network device determines that the scheduling strategy for the resources of the first link is the second scheduling strategy.

[0557] In the above situation A2, the first network device determines that the first link is not available for sensing based on the multiplexing indication signal, and therefore, the first network device determines that the scheduling strategy for the resources of the first link is the second scheduling strategy.

[0558] Here, the first scheduling strategy and the second scheduling strategy can be respectively analogous to scheduling strategy 1 and scheduling strategy 2 of method 100. The specific description of the first scheduling strategy and the second scheduling strategy can refer to the above description of scheduling strategy 1 and scheduling strategy 2, and will not be repeated here.

[0559] Based on the above manner, the first network device determines the scheduling strategy of the resources of the first link, and determines the scheduling information based on the scheduling strategy of the first link.

[0560] As mentioned above, as a device that determines resource scheduling, the first network device will not only schedule resources for the first device based on the scheduling strategy for resources determined for the first link during the resource scheduling process, but will also schedule resources in combination with the resources of all devices connected to the first network device and different services. Therefore, the first resource ultimately scheduled for the first device may differ from the scheduling strategy determined based on link measurement, and there is no absolute correlation between the two.

[0561] In the case where the first device sends a measurement report including multiplexing indication information (such as case 1 and case 2), the scheduling strategy for resources of the first link determined by the first network device is the first scheduling strategy or the second scheduling strategy, and the scheduling information determined based on the first scheduling strategy or the second scheduling strategy may be the first scheduling information.

[0562] It should be understood that the specific contents of the first scheduling information determined based on the first scheduling strategy and the first scheduling information determined based on the second scheduling strategy may be the same or different, depending on the overall resource management and control of the first network device.

[0563] For example, the first resource indicated by the first scheduling information determined based on the first scheduling policy includes a communication-aware resource, and the first resource indicated by the first scheduling information determined based on the second scheduling policy includes a perception-only resource and a communication-aware resource. For another example, the first resource indicated by the first scheduling information determined based on the first scheduling policy includes a communication-aware resource, and the first resource indicated by the first scheduling information determined based on the second scheduling policy includes a perception-only resource. For another example, the specific location of the first resource indicated by the first scheduling information determined based on the first scheduling policy is different from the specific location of the first resource indicated by the first scheduling information determined based on the second scheduling policy.

[0564] Regarding the first scheduling information, in some embodiments, the first scheduling information includes purpose information, and the purpose information is used to determine: the first resource is only used for communication, or the first resource is only used for sensing, or at least part of the first resource is used for sensing and communication; or,

[0565] The downlink control information DCI carrying the first scheduling information is scrambled with a radio network temporary identifier RNTI, where the RNTI is used to indicate that: the first resource is only used for communication, or the first resource is only used for perception, or at least part of the first resource is used for perception and communication.

[0566] In some embodiments, the first scheduling information also includes priority information; and, when at least part of the first resources overlap with other resources in the time domain and frequency domain, the priority information is used to indicate that at least part of the resources preferentially carry communication signals or preferentially carry perception signals, wherein the first resource is a perception resource and the other resources are communication resources, or the first resource is a communication resource and the other resources are perception resources.

[0567] The first scheduling information here is analogous to the scheduling information of method 100, and the first resource is analogous to resource 1 of method 100. For the specific description of the first scheduling information and the first resource, please refer to the above description of the scheduling information and resource 1, which will not be repeated here.

[0568] In step S330, the first network device sends first scheduling information.

[0569] Correspondingly, the first device receives the first scheduling information, and determines the first resource based on the first scheduling information.

[0570] In an embodiment where the first resource includes a communication sensing resource, the first device performs sensing based on a communication signal transmitted on the communication sensing resource, and the type of the first device in different scenarios and the device that performs sensing in collaboration with the first device are different.

[0571] For scenarios where the first network device and the first device perform perception, such as scenarios 1 and 2 above, the first network device and the first device perform perception based on the communication signal transmitted on the communication perception resource. In scenario 1, the first device is the first terminal device, and in scenario 2, the first device is the second network device. In scenario 3 above, the first terminal device (an example of the first device) and the second terminal device perform perception based on the communication signal transmitted on the communication perception resource. In scenario 4 above, the first terminal device (an example of the first device) performs self-transmission and self-reception, and performs perception based on the communication signal transmitted on the communication perception resource.

[0572] In the above-mentioned case 3 or case A3 where the first device does not send a measurement report, when the first network device does not receive a measurement report obtained by the first device measuring the first link based on the multiplexing measurement condition, the first network device determines that the scheduling strategy for the resources of the first link is the third scheduling strategy, and the third scheduling strategy is used to indicate that the perception resources and the communication resources of the first link do not affect each other in the time domain and / or frequency domain. In addition, the first network device determines the second scheduling information based on the third scheduling strategy and sends the second scheduling information, wherein the second scheduling information is used to indicate the second resource, and the second resource includes at least one resource: perception-only resource, communication-only resource, and communication perception resource.

[0573] It should be understood that the specific content of the second scheduling information determined based on the third scheduling strategy and the first scheduling information determined based on the first scheduling strategy or the second scheduling strategy above may be the same or different, depending on the overall resource management of the first network device.

[0574] Here, the third scheduling strategy, the second scheduling information, and the second resource can be respectively analogous to the scheduling strategy 3, scheduling information, and resource 1 of method 100. For the specific description of the third scheduling strategy, the second scheduling information, and the second resource, please refer to the relevant description above and will not be repeated here.

[0575] Fig.18 It is a schematic flow chart of the synaesthesia integration method 400 provided in an embodiment of the present application.

[0576] In method 400, the first network device and the first device are continued to be taken as examples to describe method 400 from the perspective of the interaction between the first network device and the first device. The first network device interacts with the first device. As the first network device of the measurement node, the first network device measures the communication link (hereinafter referred to as the first link) currently used to transmit the communication signal based on the multiplexing measurement condition to determine whether the first link can be used for perception. The first network device comprehensively considers the scheduling of communication resources and perception resources based on the measurement situation of the first link.

[0577] Method 400 is analogous to method 200. Specifically, the first network device of method 400 is analogous to the first network device of method 200, the first device of method 400 is analogous to the first device of method 200, and the first link of method 400 is analogous to link 2 of method 100; the applicable scenarios of method 400 are the same as the applicable scenarios of method 200 (scenario 5 and scenario 6 described above), and correspondingly, the explanations of the first device and the first link in different scenarios are also the same as the explanations of the first device and link 2 of method 200, so the specific description here can refer to the relevant description above and will not be repeated.

[0578] In step S410, the first network device measures the first link (communication link) based on the multiplexing measurement condition to obtain a measurement result for the first link.

[0579] In some embodiments, a multiplexing measurement condition is configured in the first network device.

[0580] In some other embodiments, other devices (such as core network elements) send information indicating information multiplexing measurement conditions to the first network device, so that the first network device obtains the multiplexing measurement conditions.

[0581] For a detailed description of the multiplexing measurement conditions, reference may be made to the related description of the multiplexing measurement conditions in method 200, which will not be described in detail herein.

[0582] Before step S410, the first device may send measurement assistance information to the first network device to assist the first network device in link measurement. For a detailed description of the measurement assistance information, reference may be made to the relevant description of the measurement assistance information in method 200, which will not be repeated here.

[0583] In step S420, the first network device determines scheduling information according to the measurement result.

[0584] In this step, in some embodiments, the first network device determines a scheduling strategy for resources of the first link according to the measurement result, and determines scheduling information based on the scheduling strategy for resources of the first link. Fig.16 Provide explanation.

[0585] In one example, when it is determined based on measurement results that the first link satisfies the first type of conditions, the second type of conditions, and the perception requirements (ie, case B1-1), the first network device determines that the scheduling strategy for the resources of the first link is a first scheduling strategy, and the first scheduling strategy is used to indicate that the communication resources of the first link are available for perception.

[0586] In another example, when it is determined based on the measurement results that the first link meets the first type of conditions, the second type of conditions and does not meet the perception requirements (i.e., situation B1-2), the first network device determines that the scheduling strategy for the resources of the first link is the second scheduling strategy, and the second scheduling strategy is used to indicate that the perception resources are orthogonal to the communication resources of the first link in the time domain and / or frequency domain.

[0587] In another example, when it is determined according to the measurement result that the first link meets the first type of conditions but does not meet the second type of conditions (ie, case B2), the first network device determines that the scheduling policy for the resources of the first link is the second scheduling policy.

[0588] In another example, when it is determined based on the measurement results that the first link does not meet the first type of conditions (i.e., situation B3), the first network device determines that the scheduling strategy for the resources of the first link is a third scheduling strategy, and the third scheduling strategy is used to indicate that the perception resources and the communication resources of the first link do not affect each other in the time domain and the frequency domain.

[0589] Here, the first scheduling strategy, the second scheduling strategy and the third scheduling strategy can be respectively analogous to the scheduling strategy 1, scheduling strategy 2 and scheduling strategy 3 of method 200. The specific descriptions of the first scheduling strategy, the second scheduling strategy and the third scheduling strategy can be respectively referred to the above related descriptions of scheduling strategy 1, scheduling strategy 2 and scheduling strategy 3, and will not be repeated here.

[0590] Based on the above method, the first network device determines the scheduling strategy of the resources of the first link, and determines the scheduling information based on the scheduling strategy of the first link, the scheduling information is used to indicate the first resource, and the first resource includes at least one resource: perception-only resource, communication-only resource, and communication-perception resource.

[0591] The scheduling information here is analogous to the scheduling information of method 200, and the first resource is analogous to resource 2 of method 200. For the specific description of the scheduling information and the first resource, please refer to the above description of the scheduling information and resource 2, which will not be repeated here.
