[0001] The present application claims priority from the Chinese patent application No. 202411377709.3 filed on September 30, 2024, and entitled "A method and device for integrating sensing and communication", the whole content of which is incorporated herein by reference. TECHNICAL FIELD

[0002] The present application relates to the field of communication and sensing, and more particularly, to a method and device for integrating sensing and communication in the field of communication and sensing. BACKGROUND

[0003] With the emergence of emerging business scenarios such as automatic driving and virtual reality, mobile communication systems such as the 5th generation mobile communication technology (5G) or the 6th generation mobile communication technology (6G) need to have both communication ability and sensing ability. There is a certain similarity between sensing technology and communication technology in terms of spectrum, waveform and antenna design, and thus the research on integrated sensing and communication (ISAC) is promoted. ISAC refers to a new type of information processing technology based on sharing of software and hardware resources or information sharing to simultaneously realize the coordination of sensing and communication functions, which can effectively improve the spectrum efficiency of the system, save hardware space and reduce maintenance costs.

[0004] In the ISAC system, wireless resources need to be able to perform sensing and communication, and therefore, how to manage and allocate wireless resources is a problem currently concerned in the ISAC system. SUMMARY

[0005] The present application provides a method and device for integrating sensing and communication, which can improve the utilization rate of resources as much as possible to maximize the use of wireless resources and thus improve the system performance.

[0006] In a first aspect, a method for sensing and communication integration is provided, and is applied to a first device. The method comprises: sending, to a first network device, a measurement report obtained by the first device based on a multiplexing measurement condition for measuring a first link, the multiplexing measurement condition being used to determine a communication link available for sensing, the first link being a communication link currently used for transmitting a communication signal, the measurement report comprising multiplexing indication information, the multiplexing indication information being used to indicate whether the first link is available for sensing; and receiving first scheduling information sent by the first network device according to the measurement report, the first scheduling information being used to indicate a first resource, the first resource comprising at least one of the following resources: only sensing resource, only communication resource, and communication and sensing resource.

[0007] The method for sensing and communication integration provided by the embodiments of the present application can make the first network device determine whether the first link is available for sensing based on the measurement report obtained by measuring the first link, and then the first network device can comprehensively consider the scheduling of the resources for communication and sensing, and indicate the resources (e.g., the first resource) scheduled for the first device by sending scheduling information to the first device, the scheduled resources comprising at least one of the following resources: only sensing resource, only communication resource, and communication and sensing resource. In this way, when the scheduled resources comprise the communication and sensing resource, the first device can perform communication and sensing based on the same resource (communication and sensing resource) on the first link, i.e., sensing based on the communication signal transmitted on the communication and sensing resource. In this way, since no additional sensing resource is needed, the occupation of the sensing resource is reduced, and the resource utilization rate can be effectively improved. When the scheduled resources comprise only sensing resource or only communication resource, the normal communication and sensing can be maintained as much as possible, and the interference between communication and sensing is reduced. Therefore, the scheme of measuring the first link (i.e., the communication link) currently used for transmitting a communication signal based on a multiplexing measurement condition to determine whether the communication resource of the first link is available for sensing in the embodiments of the present application can provide a multiplexing basis for the scheduling of the resources for communication and sensing, can improve the resource utilization rate as much as possible in the case of maintaining the normal communication and sensing as much as possible, can maximize the utilization of wireless resources, and thus the system performance is improved.

[0008] In some embodiments, the multiplexing measurement condition comprises a first type of condition, and the first type of condition is used to determine a communication link capable of providing sensing information.

[0009] In the above embodiments, the first type of condition determines the communication link that can provide the sensing information, which means that the first device can obtain the information (sensing information) related to the sensing target or the sensing area, and thus the communication link that can provide the sensing information is likely to be used for sensing, and the feasibility of the measurement of whether the communication link can be used for sensing is ensured as much as possible.

[0010] In some embodiments, the first type of condition includes at least one of the following conditions:

[0011] The first condition: the communication node on the communication link has an association relationship with the sensing target;

[0012] The second condition: the communication beam on the communication link can be used for sensing;

[0013] The third condition: the scatterer on the communication link is within the sensing area;

[0014] The fourth condition: the distance between the communication node on the communication link and the center position of the sensing area is less than a first threshold, or the distance between the communication node on the communication link and the sensing target is less than a second threshold.

[0015] In some embodiments, the multiplexing measurement condition further includes a second type of condition, and the second type of condition is related to the communication signal.

[0016] In the above embodiments, the second type of condition focuses on the characteristics of the communication channel of the communication link, and more focuses on the channel condition of the communication channel. If the first link (communication link) currently measured can provide the sensing information, but the channel condition of the communication channel of the first link is not ideal, which leads to the poor performance of the received communication signal, and also means that the performance of the sensing based on the communication signal of the first link is also poor, which affects the effect of the sensing. Therefore, in combination with the first type of condition, the second type of condition is used to measure the communication link, which can evaluate the channel condition of the communication channel based on the communication signal, select the communication link with the ideal channel condition and the communication link that can provide the sensing information, and improve the effect of the sensing in the link (or resource) multiplexing.

[0017] In some embodiments, the second type of condition includes at least one of the following conditions:

[0018] The fifth condition: the signal quality of the communication signal received on the communication link is greater than or equal to a signal quality threshold;

[0019] The sixth condition: the maximum Doppler shift of the communication signal received on the communication link is less than or equal to a Doppler shift threshold;

[0020] The seventh condition: in the case that the communication link is a multipath link, the power of each of the at least one sub-link of the communication link is greater than or equal to a power threshold, or the power ratio of the power of each of the at least one sub-link of the communication link to the power of the communication link is greater than or equal to a power ratio threshold;

[0021] The eighth condition: in the case that the communication link is a multipath link, the signal quality of the communication signal received on each of the at least one sub-link of the communication link is greater than or equal to a signal quality threshold;

[0022] The ninth condition: in the case that the communication link is a multipath link, the maximum Doppler shift of the communication signal received on each of the at least one sub-link of the communication link is less than or equal to a Doppler shift threshold.

[0023] In the above step of sending the measurement report to the first network device, the measurement report is sent to the first network device in the case that the first link satisfies the first type of condition and the second type of condition, wherein the multiplexing indication information is used to indicate that the first link can be used for sensing; or the measurement report is sent to the first network device in the case that the first link satisfies the first type of condition and does not satisfy the second type of condition, wherein the multiplexing indication information is used to indicate that the first link cannot be used for sensing.

[0024] In some embodiments, in the case that the first link does not satisfy the first type of condition, the measurement report is not sent to the first network device.

[0025] In the above embodiment, in the case that the first link does not satisfy the first type of condition, the first device does not send the measurement report to the first network device, and the first network device can be sure that the first link does not satisfy the first condition in the case that the measurement report is not received, which can effectively save signaling overhead compared with the signaling mode.

[0026] 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:

[0028] First Doppler shift information, used to indicate the maximum Doppler shift and / or Doppler spread of the communication signal received on the first link;

[0029] First signal information, used to indicate the signal quality of the communication signal received on the first link;

[0030] The second signal information is used for indicating the signal quality of the communication signal received on the sub-link satisfying the multiplexing measurement condition in the first link in the case that the first link is a multipath link.

[0031] The power information is used for indicating the power ratio of the power of the sub-link satisfying the multiplexing measurement condition in the first link to the power of the first link in the case that the first link is a multipath link.

[0032] The second Doppler shift information is used for indicating the maximum Doppler shift of the communication signal received on the sub-link satisfying the multiplexing measurement condition in the first link in the case that the first link is a multipath link.

[0033] In the above embodiment, in the case that the multiplexing indication information is used for indicating that the first link can be used for sensing, the measurement report sent by the first device further comprises sensing assistance information, which can enable the first network device to determine whether the first link satisfies the sensing requirement in combination with the sensing measurement information, to finally determine whether the first link can be sensed, which is equivalent to increasing the measurement requirement for the communication link, and can finally determine the communication link with good sensing effect, and improve the sensing performance when the link (or resource) is multiplexed for sensing.

[0044] In the above embodiment, the function of the first resource scheduled by the scheduling information is indicated by the RNTI of the DCI carrying the scheduling information, so that the signaling overhead can be reduced without adding additional information or fields.

[0045] In some embodiments, the first scheduling information further includes priority information, and in the case that at least part of the first resource overlaps with other resources in the time domain and the frequency domain, the priority information is used to indicate that the at least part of the resource preferentially carries a communication signal or preferentially carries a sensing signal, wherein the first resource is a sensing resource, and the other resource is a communication resource, or the first resource is a communication resource, and the other resource is a sensing resource.

[0137] The technical solutions in the present disclosure will be described below with reference to the accompanying drawings.

[0138] 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 sensing capabilities. There is a certain similarity between sensing technology and communication technology in terms of spectrum, waveform, and antenna design, and thus research on integrated sensing and communication (ISAC) is promoted, which is a new type of information processing technology based on software and hardware resource sharing or information sharing to simultaneously realize the coordination of sensing and communication functions, and can effectively improve system spectrum efficiency, save hardware space, and reduce maintenance costs.

[0139] In an ISAC system, wireless resources are used for both communication and sensing, and how to manage and allocate wireless resources is a problem currently concerned in ISAC systems. In related technologies, different resources are allocated for sensing and communication to realize their respective functions, that is, the allocated sensing resources are only used for sensing, 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 sensing will inevitably cause resource contention, thereby reducing the performance of the system.

[0140] Therefore, in order to maximize the use of wireless resources as much as possible to improve system performance, the embodiments of the present application provide a sensing and communication integrated method, which measures a communication link (such as a first link) of a current transmission communication signal based on a multiplexing measurement condition, wherein the multiplexing measurement condition is used to determine a communication link available for sensing, so that the network device can determine whether the communication resource of the communication link is used for sensing (or whether the communication resource is multiplexable) based on a measurement report obtained by measuring the link. Further, the network device can consider the scheduling of the resources for communication and sensing based on whether the communication resource of the communication link is used for sensing, and indicate the scheduled resources (such as first resources) through scheduling information, wherein the scheduled resources include at least one of sensing-only resources, communication-only resources and communication-sensing resources, and the communication-sensing resources are used for communication and sensing, and sensing can be performed based on a communication signal transmitted on the communication-sensing resources. In this way, in the case where the scheduled resources include communication-sensing resources, since sensing can be performed based on a communication signal transmitted on the communication-sensing resources, no additional sensing resources are needed, the occupation of sensing resources is reduced, and therefore the resource utilization rate can be effectively improved; in the case where the scheduled resources include sensing-only resources or communication-only resources, the normal communication and sensing can be maintained as much as possible, and the interference between communication and sensing is reduced. Therefore, the embodiments of the present application measure the communication link based on the multiplexing measurement condition to determine whether the communication resource of the communication link is used for sensing, which can provide a multiplexing basis for the scheduling of the resources for communication and sensing, and improve the resource utilization rate as much as possible to maximize the use of wireless resources, thereby improving system performance.

[0141] It should be understood that the communication-sensing resources described in the embodiments of the present application are used for sensing and communication, which means that the signals transmitted on the communication-sensing resources can be used for both communication and sensing, i.e., the signals transmitted on the communication-sensing resources have two functions, one function is to realize communication and the other function is to realize sensing. When sensing is performed based on the communication-sensing resources, specifically, sensing is performed based on the communication signals transmitted on the communication-sensing resources.

[0142] Hereinafter, first, the related terms of the embodiments of the present application are introduced.

[0143] 1. Communication node, communication link

[0144] The communication node usually has the ability to receive and process communication signals, such as a network device or a terminal device.

[0145] A communication link refers to a link for carrying a communication signal. In some scenarios, the communication link is a link between two communication nodes for communication, for example, the communication link is a link between a network device and a terminal device for carrying a communication signal, and the communication link shown in Fig. 1(b) can be a downlink communication link A1 or an uplink communication link A2. In other scenarios, one communication node transmits a communication signal to another communication node, and there is a scatterer between the two communication nodes, the communication signal is reflected or scattered by the scatterer, and the reflected or scattered communication signal reaches the communication node that transmits the communication signal, in this scenario, the communication link includes a link from the communication node that transmits the communication signal to the scatterer and a link from the scatterer to the communication node after the communication signal is reflected or scattered by the scatterer, and the communication link shown in Figs. 7 and 8 can be a communication link formed by the communication link A11 and the communication link A13.

[0146] It should be understood that the communication signal of the embodiments of the present application refers to any signal transmitted on a communication resource, which can be a signal carrying data or information with specific meaning, or a reference signal, which is not limited in the present application.

[0147] 2. Sensing node, sensing target, sensing link

[0148] In the ISAC system, for sensing services, sensing is performed by analyzing direct, reflected, or scattered signals of sensing signals, and the environment is sensed by using characteristics of received signals to complete positioning, ranging, speed measurement, imaging, detection, identification, environment reconstruction, and other functions, to achieve sensing exploration of the physical world.

[0149] In the ISAC system, nodes participating in the transmission, reception, and processing of sensing signals include at least sensing nodes and sensing targets. The processing of sensing signals includes various processes before the sensing signals are transmitted, such as physical layer or radio frequency end processes such as encoding and modulation, power control, antenna control, and other physical layer or radio frequency end processes before the sensing signals are transmitted. The processing of sensing signals also includes various processes after the sensing signals are received, such as decoding and demodulation, interference cancellation, and other physical layer or radio frequency end processes after the sensing signals are received. For the reception of sensing signals, the sensing node can receive direct signals of the sensing signals (i.e., sensing signals) or receive reflected or scattered signals of the sensing signals (also referred to as echo signals). Therefore, in the embodiments of the present application, the reception of sensing signals by a certain node or device described below can be the reception of direct signals of the sensing signals (i.e., sensing signals) or the reception of reflected or scattered signals of the sensing signals (echo signals).

[0150] The sensing node usually has the capability of transmitting, receiving, and processing sensing signals, such as a network device or a terminal device.

[0151] The perception target can be an active perception target or a passive perception target.

[0152] The active perception target has the ability to transmit, receive and process the perception signal. The perception signal transmitted by the active perception target is received and processed, thereby realizing the functions of positioning, detecting, tracking and identifying the perception target. Common active perception targets can include devices such as mobile phones, vehicles, Internet of Things devices, etc. In the ISAC system, the signals transmitted by these active targets can be used for integrated processing of communication and perception, improving spectrum utilization and overall system performance. For example, in an intelligent transportation system, vehicles as active perception targets, their transmitted GPS signals and communication signals can be received by roadside ISAC base stations for vehicle positioning, traffic monitoring and road condition analysis.

[0153] The passive perception target usually does not have the ability to transmit, receive and process the perception signal, and the simplest passive perception target can only reflect or scatter electromagnetic waves. Passive perception targets can include a wide range of physical environments such as buildings, urban facilities (such as billboards, bridges, etc.), traffic conditions (such as pedestrians, bicycles), etc. 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 perception 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 by them.

[0154] Currently, there are mainly two kinds of perception modes in the industry: A-to-B perception mode and self-to-self perception mode. In the A-to-B perception mode, the perception node that transmits the perception signal and the perception node that receives the perception signal are different, and in the self-to-self perception mode, the perception node that transmits the perception signal and the perception node that receives the echo signal of the perception signal are the same perception node.

[0155] 3. Communication resource, only communication resource, perception resource, only perception resource, communication and perception resource

[0156] Communication and sensing resource, which means a resource used for both communication and sensing. Based on the signal transmitted on the communication and sensing resource, both communication and sensing can be achieved, i.e., the signal transmitted on the communication and sensing resource has two functions, one is to achieve the function of communication, and the other is to achieve the function of sensing. When sensing is performed based on the communication and sensing resource, specifically, sensing is performed based on the communication signal transmitted on the communication and sensing resource. It should be understood that the communication signal transmitted on the communication and sensing resource can be a signal with specific meaning carrying data or information, or a reference signal. The communication and sensing resource includes but is not limited to time domain resource, frequency domain resource, and space domain resource.

[0157] Communication resource, which means a resource used for communication. Communication is performed through the communication signal carried on the communication resource. The communication resource includes but is not limited to time domain resource, frequency domain resource, and space domain resource. The space domain resource of the communication resource can include a communication beam.

[0158] Only communication resource, which means a resource used only for communication.

[0159] For the communication resource, if a part of the communication resource can also be used for sensing, the communication resource can include only communication resource and communication and sensing resource.

[0160] Sensing resource, which means a resource used for sensing. Sensing is performed through the sensing signal carried on the sensing resource. The sensing resource includes but is not limited to time domain resource, frequency domain resource, and space domain resource. The space domain resource of the sensing resource can include a sensing beam.

[0161] Only sensing resource, which means a resource used only for sensing.

[0162] For the sensing resource, if a part of the sensing resource can also be used for communication, the sensing resource includes only sensing resource and communication and sensing resource.

[0163] In order to facilitate understanding of the embodiments of the present application, next, the sensing scenario and the communication scenario in the ISAC system are briefly introduced in combination with FIGS. 1 to 8.

[0164] FIGS. 1 to 8 are schematic diagrams of the sensing scenario and the communication scenario of the ISAC system provided by the embodiments of the present application.

[0165] In the sensing scenarios shown in FIGs. 1-3, the sensing mode is a mode in which one sensing node transmits a sensing signal, the sensing target reflects or scatters the sensing signal, and another sensing node receives the signal reflected or scattered by the sensing target. In the communication scenarios shown in FIGs. 1-3, the communication link is a link between two communication nodes, and on the communication link, a communication signal transmitted by one communication node reaches another communication node after being reflected or scattered by a scatterer.

[0166] In the sensing scenario shown in (a) of FIG. 1, network device A and terminal device A serve as sensing nodes. In sensing link B1, network device A transmits a sensing signal, terminal device A receives the signal reflected or scattered by the sensing signal, and performs sensing based on the received signal. In sensing link B2, terminal device A transmits a sensing signal, and network device A receives the signal reflected or scattered by the sensing signal, and performs sensing based on the received signal.

[0167] In the communication scenario shown in (b) of FIG. 1, network device A and terminal device A serve as communication nodes. In communication link A1, network device A transmits a communication signal, the communication signal is reflected or scattered by a scatterer, and terminal device A receives the signal reflected or scattered by the communication signal. In communication link A2, terminal device A transmits a communication signal, the communication signal is reflected or scattered by a scatterer, and network device A receives the signal reflected or scattered by the communication signal.

[0168] The sensing scenario and the communication scenario shown in FIG. 2 are similar to the sensing scenario and the communication scenario shown in FIG. 1, and the difference between the two is the difference in sensing nodes and communication nodes. In (a) of FIG. 2, the sensing nodes in the sensing scenario are network device A and network device B. In (b) of FIG. 2, the communication nodes in the communication scenario are also network device A and network device B.

[0169] The sensing scenario and the communication scenario shown in FIG. 3 are similar to the sensing scenario and the communication scenario shown in FIG. 1, and the difference between the two is the difference in sensing nodes and communication nodes. In (a) of FIG. 3, the sensing nodes in the sensing scenario are terminal device A and terminal device B. In (b) of FIG. 3, the communication nodes in the communication scenario are also terminal device A and terminal device B.

[0170] In addition, the terminal device A also interacts with the network device A, and the network device A schedules related resources (such as scheduling information) or transmits related information (such as measurement indication information below) or transmits related data for the terminal device A. The terminal device B also interacts with the network device B, and the network device B schedules related resources (such as scheduling information) or transmits related information (such as measurement indication information below) or transmits related data for the terminal device B. In an example, the network device A and the network device B are the same device, and in another example, the network device A and the network device B are different devices.

[0171] In FIGS. 1-3, the perception link is a link between two perception nodes, and the communication link is a link between two communication nodes.

[0172] In the communication scenario shown in FIGS. 1-3, when the scatterer in the communication link (such as the communication link Al or the communication link A2) is the perception target, the perception target can also act as a scatterer of the communication link, and the communication link can provide perception information. At this time, the perception target can be a shared scatterer of 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, the communication resources of the communication link can be considered for multiplexing, or in other words, the communication resources of the communication link are used as communication perception resources, and perception is performed through the communication signal transmitted on the communication resources of the communication link to improve resource utilization. The specific process can be referred to the related description below, and will not be described here.

[0173] In the perception scenario shown in FIGS. 4-6, the perception mode is the A-to-B reception perception mode, the perception target is an active perception target, and the perception target is any perception node. One perception node transmits a perception signal, and the other perception node receives the perception signal. In the communication scenario shown in FIGS. 4-6, the communication link is a link between two communication nodes, and on the communication link, one communication node transmits a communication signal, and the other communication node receives the communication signal.

[0174] In the sensing scenario shown in (a) of FIG. 4, network device A and terminal device A are sensing nodes, in sensing link B1, network device A transmits a sensing signal, terminal device A receives a signal directly reflected by the sensing signal, and performs sensing according to the received signal, where the sensing target can be network device A or terminal device A, which is determined based on actual conditions, and the embodiments of the present application do not make any limitation. In sensing link B2, terminal device A transmits a sensing signal, network device A receives a signal directly reflected by the sensing signal, and performs sensing according to the received signal, where the sensing target can be network device A or terminal device A, which is determined based on actual conditions. In the case where the sensing target in sensing link B2 is network device A, the positioning of network device A can be performed through the sensing signal received by network device A. For example, for a future mobile network device (such as an aerial base station), the mobile network device can be used as a hotspot to cover and supplement some areas, and therefore it is necessary to position such a mobile network device.

[0175] In the communication scenario shown in (b) of FIG. 4, network device A and terminal device A are communication nodes, in communication link A1, network device A transmits a communication signal, and terminal device A receives a signal directly reflected by the communication signal. In communication link A2, terminal device A transmits a communication signal, and network device A receives a signal directly reflected by the communication signal.

[0176] The sensing scenario and the communication scenario shown in FIG. 5 are similar to the sensing scenario and the communication scenario shown in FIG. 4, and the difference between the two is the difference between the sensing nodes and the communication nodes. In (a) of FIG. 5, the sensing nodes in the sensing scenario are network device A and network device B, and in (b) of FIG. 5, the communication nodes in the communication scenario are also network device A and network device B.

[0177] The sensing scenario and the communication scenario shown in FIG. 6 are similar to the sensing scenario and the communication scenario shown in FIG. 4, and the difference between the two is the difference between the sensing nodes and the communication nodes. In (a) of FIG. 6, the sensing nodes in the sensing scenario are terminal device A and terminal device B, and in (b) of FIG. 6, the communication nodes in the communication scenario are also terminal device A and terminal device B.

[0178] In addition, terminal device A also interacts with network device A, and network device A schedules related resources (such as scheduling information) or transmits related information (such as measurement indication information below) or transmits related data for terminal device A. Terminal device B also interacts with network device B, and network device B schedules related resources (such as scheduling information) or transmits related information (such as measurement indication information below) or transmits related data for terminal device B. In an 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.

[0179] In FIGs. 4-6, a sensing link is a link between two sensing nodes, and a communication link is a link between two communication nodes.

[0180] In the communication scenario shown in FIGs. 4-6, when the sensing target is a communication node (a network device or a terminal device), if a communication link (such as communication link Al or communication link A2) meets some conditions (such as multiplexing measurement conditions) for sensing, it means that the communication resources of the communication link can also be used for sensing, and therefore, the communication resources of the communication link can be considered for multiplexing, or in other words, the communication resources of the communication link are used as communication sensing resources, and sensing is performed through a communication signal transmitted on the communication resources of the communication link, so as to improve resource utilization. The specific process can be referred to the related description below, and will not be described here.

[0181] In the sensing scenario shown in FIGs. 7 and 8, the sensing mode is a self-transmitting and self-receiving sensing mode, and the sensing target is a passive sensing target. A same sensing node transmits a sensing signal and receives a signal reflected or scattered by the sensing target. In the communication scenario shown in FIGs. 7 and 8, in a first case, a communication link is a link between two communication nodes, and on the communication link, one communication node transmits a communication signal and the other communication node receives the communication signal. In addition, in a second case, one communication node transmits a communication signal, and the communication signal is reflected or scattered by a scatterer, and the communication node that transmits the communication signal also receives the reflected or scattered communication signal. In this case, the communication link can include a link from the communication node that transmits the communication signal to the scatterer and a link from the scatterer to the communication node that transmits the communication signal. It should be understood that in the communication scenario, the communication link in the second case is generated in the process of transmitting and receiving the communication signal between the two communication nodes, although the communication link in the second case carries the communication signal, generally, 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.

[0182] In the sensing scenario shown in FIG. 7, network device A is a sensing node, and the sensing signal transmitted by network device A is reflected or scattered by a sensing target through sensing link B11 and then reaches network device A through sensing link B12. Network device A receives the reflected or scattered sensing signal carried on sensing link B12. In this scenario, the sensing link formed by sensing link B11 and sensing link B12 is used for sensing in the self-transmitting and self-receiving sensing mode.

[0183] In the communication scenario shown in FIG. 7, the network device A can be a communication node, and the terminal device A is another communication node. The network device A sends a communication signal to the terminal device A, and the communication signal is transmitted to the terminal device through the communication link A11 and the communication link A12, which form a communication link similar to the communication link between the two communication nodes shown in FIG. 1. In addition, the communication signal on the communication link A11 is reflected or scattered by the scatterer and then returns 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 referred to as a communication link, that is, the communication link includes the communication link A11 and the communication link A13. The communication link A11 is a link through which the communication signal sent by the network device A reaches the scatterer from the network device A. The communication link A13 is a link through which the communication signal reflected or scattered by the scatterer reaches 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.

[0184] The sensing scenario and the communication scenario shown in FIG. 8 are similar to the sensing scenario and the communication scenario shown in FIG. 7, and the difference between the two is the difference between the sensing node and the communication node. In FIG. 8, the sensing node in the sensing scenario is the terminal device A, and the communication node in the communication scenario is also the terminal device A. In addition, the terminal device A also interacts with the network device A, and the network device A schedules related resources (such as scheduling information) or transmits related information (such as measurement indication information described below) or transmits related data for the terminal device A.

[0185] In the communication scenarios shown in FIG. 7 and FIG. 8, when the scatterer on the communication link (such as the communication link formed by the communication link A11 and the communication link A13) shown in FIG. 7 and FIG. 8 is a sensing target, if the communication link meets some conditions (such as multiplexing measurement conditions) for sensing, it means that the communication resources of the communication link can also be used for sensing. Therefore, the communication resources of the communication link can be considered to be multiplexed, or in other words, the communication resources of the communication link are used as communication sensing resources, and sensing is performed through the communication signal transmitted on the communication resources of the communication link to improve resource utilization. The specific process can be referred to the related description below, which will not be described here.

[0186] The terminal device of the embodiments of the present application is a device with wireless transceiving function, which can be deployed on land, including indoor or outdoor, handheld, wearable or vehicle-mounted; can also be deployed on water surface (such as ships, etc.); can also be deployed in the air (such as airplanes, balloons and satellites, etc.).

The terminal can also be referred to as a terminal device, a user equipment (UE), an access terminal device, a vehicle-mounted terminal, an industrial control terminal, a UE unit, a UE station, a mobile station, a mobile station, a remote station, a remote terminal device, a mobile device, a UE terminal device, a terminal device, a wireless communication device, a UE agent or a UE apparatus, etc. The terminal device can also be fixed or mobile.

[0187] The network device in the embodiments of the present application can be a device for communication and / or sensing with the terminal device, and is any device with wireless transceiving function. The network device includes, but is not limited to, a base station (gNodeB or gNB) or a transmission receiving point (TRP) in the fifth generation (5G), new radio (NR) or future sixth generation (6G), an access node, a wireless relay node, a wireless backhaul node and the like in a WiFi system. The base station can be a macro base station, a micro base station, a pico base station, a small station, a relay station, or a balloon station, etc. The network device can also be a wireless controller, a CU, and / or a DU in a cloud radio access network (CRAN) scenario. The network device can also be a server, a wearable device, or a vehicle-mounted device, etc. In the embodiment in which the network device is a base station, multiple network devices can be the same type of base station or different types of base stations; the base station can communicate and / or sense with the terminal device, or communicate and / or sense with the terminal device through a relay station; the terminal device can communicate and / or sense with multiple base stations of different technologies, for example, the terminal device can communicate with a base station supporting an LTE network or a 5G network or a future 6G network, and the terminal device can also support sensing with a base station of a 5G network or a 6G network.

[0188] Hereinafter, the method for integrating communication and sensing according to the embodiments of the present application is described in detail based on different communication scenarios shown in FIGS. 1 to 8.

[0203] Scenario 4

[0204] The link 1 is a link between a first terminal device and a scatterer. The link 1 includes a link of a communication signal transmitted by the first terminal device from the first terminal device to the scatterer and a link of the communication signal reflected or scattered by the scatterer from the scatterer to the first terminal device.

[0205] Please refer to FIG. 8, the link 1 is a link between a terminal device A (an example of a first terminal device) and a scatterer, the link 1 includes a communication link A11 and a communication link A13, the terminal device A is a communication node for transmitting and receiving a communication signal, and the terminal device A is a measurement node for link measurement, and a network device A interacting with the terminal device A comprehensively considers allocation of a communication resource and a sensing resource based on a measurement situation of the link 1. In one example of FIG. 8, a scatterer on the link 1 is a sensing target.

[0206] In the method 100, a first device is a measurement node for link measurement, and the first device acquires measurement indication information to perform link measurement based on the measurement indication information.

[0207] In some embodiments, in step S110, the first network device sends the measurement indication information to the first device. Correspondingly, the first device receives the measurement indication information.

[0208] In some other embodiments (not shown in the figure), other devices (such as core network elements) send the measurement indication information to the first device, and correspondingly, the first device receives the measurement indication information sent by the other devices.

[0209] In step S120, the first device measures the link 1.

[0210] In this step, the first device measures the link 1 based on the measurement indication information to obtain a measurement report.

[0211] As mentioned above, the link 1 is a communication link currently used for transmitting communication signals, and the interpretation of the link 1 is different in different scenarios, which can be referred to the relevant description above.

[0212] In some embodiments, the measurement indication information includes condition information, and the condition information is used to indicate a multiplexing measurement condition used to determine a communication link that can be perceived. After receiving the measurement indication information, the first device measures the link 1 (communication link) used for transmitting communication signals based on the multiplexing measurement condition indicated by the condition information to determine whether the link 1 can be used for perception.

[0213] It should be understood that the multiplexing measurement condition can include any condition of content as long as the communication link that can be perceived can be determined, and the embodiments of the present application do not make any limitation, and the multiplexing measurement condition will be described in detail below, which is not described here.

[0214] In scenarios 1 and 2 described above, in some other embodiments, the measurement indication information can not only include the condition information, but also include measurement assistance information to assist the first device to perform link measurement, wherein the measurement assistance information includes at least one of the following information.

[0215] The position information of the first network device, used to indicate the position of the first network device.

[0216] Information of a sending communication beam (denoted as a second communication beam) on the link 1, and the sending communication beam on the link 1 and the second communication beam are alternative descriptions, and the sending communication beam (second communication beam) on the link 1 represents a communication beam that transmits a communication signal on the link 1. Exemplarily, the information of the sending communication beam on the link 1 can include a beam identifier (such as a beam ID), a beam width and a beam pointing. The beam pointing includes an azimuth and a zenith, and the beam width includes a horizontal beam width and a vertical beam width.

[0217] The information of the perception target includes location information indicating a location of the perception target. Exemplarily, the information of the perception target can further include information indicating an attribute of the perception target, such as a person, a building, a vehicle, a city facility, etc., without any limitation.

[0218] The information of the perception area includes location information indicating a location of the perception area. Exemplarily, the information of the perception area can further include information indicating other parameters of the perception area, without any limitation.

[0219] The information of the first perception beam is a perception beam used by the first network device to transmit the perception signal. Exemplarily, the information of the first perception beam can include a beam identifier (such as a beam ID), a beam width, and a beam pointing direction.

[0220] The above measurement assistance information can be used in combination with different conditions of the multiplexed measurement condition. For details, reference can be made to the related description of the process of link measurement based on each condition below, which will not be described herein again.

[0221] In the following, the multiplexed measurement condition and the process of link measurement based on the multiplexed measurement condition are further described.

[0222] In some embodiments, the multiplexed measurement condition includes a first type of condition for determining a communication link capable of providing perception information.

[0223] It should be understood that the communication link capable of providing perception information described herein means that, after the first device as a measurement node processes a communication signal received on the communication link, perception information related to a perception target or a perception area can be obtained. The perception information can include any content related to the perception target or the perception area, for example, the perception information can include information indicating a location of the perception target or the perception area, a moving speed of the perception target, and / or a moving trajectory of the perception target, etc.

[0224] It should also be understood that if the currently measured link 1 (communication link) satisfies the first type of condition, it means that the link 1 is capable of providing perception information. If the currently measured link 1 does not satisfy the first type of condition, it means that the link 1 is not capable of providing perception information, i.e., the first device cannot obtain perception information after processing the communication signal received on the link 1.

[0225] It can be seen that the first type of condition focuses on whether the spatial resource of the communication link can be used for perception, i.e., whether the spatial resource of the communication link can be used for perception. If the spatial resource of the communication link can be used for perception, then the communication link is capable of providing perception information.

[0226] Exemplarily, the first type of conditions can include one or more conditions to jointly determine whether the communication link can provide sensing information. Details of the individual conditions regarding the first type of conditions will be described below and will not be repeated here.

[0227] In some embodiments, the multiplexing measurement conditions include the first type of conditions and the second type of conditions.

[0228] The second type of conditions is related to parameters of the communication signal, such as signal quality, Doppler shift, and the like, which are used to evaluate the characteristics of the communication channel. Details of the second type of conditions will be described below and 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.

[0229] It should be noted that the first type of conditions and the second type of conditions focus on different aspects. The first type of conditions focuses on whether the communication link can provide sensing information, and more focuses on whether the spatial domain resource of the communication link can be used for sensing. The second type of conditions focuses on the characteristics of the communication channel of the communication link, and more focuses on the channel conditions of the communication channel. It can be understood that the current measured link 1 (communication link) can provide sensing information, which means that the spatial domain resource can be used for sensing. However, if the channel conditions of the communication channel of the link 1 are not ideal, the performance of the received communication signal is not good, which means that the performance of sensing based on the communication signal of the link 1 is not good, which affects the effect of sensing. Therefore, it is not recommended to use the link 1 for sensing.

[0230] In the embodiments in which the multiplexing measurement conditions include the first type of conditions and the second type of conditions, in the step S120 of measuring the link 1 by the first device, in an example, the first device can measure the link 1 based on the first type of conditions and the second type of conditions in parallel. In another example, the link 1 can be measured according to the order of the first type of conditions and the second type of conditions, for example, the first device first measures the link 1 based on the first type of conditions, and then measures the link 1 based on the second type of conditions. The specific process of measurement is not limited here and can be determined according to the delay requirement and the computing capability and the like.

[0231] In the following, the first type of conditions and the second type of conditions are described in detail, and the way of measuring the link by the first device in combination with the first type of conditions and the second type of conditions is described.

[0232] The first type of conditions

[0233] 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.

[0234] The first condition, the communication node on the communication link has an association relationship with the sensing target.

[0235] It should be understood that if the communication node on the communication link has an association relationship with the perception target, it means that the communication link is likely to provide perception information.

[0236] For the first device (the communication node of link 1) on link 1 (the 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, link 1 meets the first condition, which means that link 1 is likely to provide perception information.

[0237] The association relationship between the communication node and the perception target can have two relationships: the first association relationship and the second association relationship.

[0238] In the first association relationship, the communication node is the perception target.

[0239] In an example, in the communication scenario as shown in (b) of FIG. 4, network device A (an example of the first network device) and terminal device A (an example of the first device) are the communication nodes of communication link A1 (an example of link 1). If terminal device A is the perception target, terminal device A as the measurement node can determine that it is the perception target.

[0240] In the second association relationship, the communication node is not the perception target, but the communication node has relevance to the perception target.

[0241] It can be understood that the communication node on the communication link has relevance to the perception target, which can enable the communication link to provide perception information.

[0242] In the second association relationship, the relevance of the communication node to the perception target can be determined by information of the communication node and information of the perception target, for example. The information of the communication node can include information indicating the position, moving speed, and / or moving track of the communication node, and the information of the perception target can include information indicating the position, moving speed, and / or moving track of the perception target. The perception target can be a passive perception target, for example.

[0243] FIG. 10 is another schematic diagram of a communication scenario provided by an embodiment of the present application.

[0244] In an example, referring to (a) of FIG. 10, the network device A (an example of the first network device) interacts with the terminal device A (an example of the first device), and the terminal device A is also a measurement node as a communication node. The sensing target is a person Xiao Li, and Xiao Li carries the terminal device A. In this case, the terminal device A is bound with the sensing target, and therefore, the sensing target has strong correlation with the communication node. In implementation, the information of the terminal device A (an example of the first device) can be compared with the information of the sensing target (Xiao Li), and if the correlation values of the contents such as the position, the moving speed, and the moving trajectory indicated by the information of the two are greater than a threshold, it means that the two have strong correlation. It can be understood that in this scenario, the terminal device A is capable of obtaining the sensing information (such as the information of the sensing target) based on the signal sent by the network device A. For example, since the terminal device A is bound with the sensing target, the information such as the position, the moving speed, and the moving trajectory of the terminal device A determined by the terminal device A based on the signal sent by the network device A can determine the information such as the position, the moving speed, and the moving trajectory of the sensing target bound with the terminal device A, and thus, the information of the sensing target is obtained.

[0245] In another example, referring to (b) of FIG. 10, the network device A (an example of the first network device) interacts with the terminal device A (an example of the first device), and the terminal device A interacts with the terminal device B. The terminal device A is also a measurement node as a communication node. The sensing target is a person Xiao Li, and Xiao Li carries the terminal device B. In this case, the terminal device B is bound with the sensing target (Xiao Li), and since the terminal device A interacts with the terminal device B, the terminal device A has strong correlation with the sensing target. In implementation, the information of the terminal device B can be compared with the information of the sensing target (Xiao Li), and if the correlation values of the contents such as the position, the moving speed, and the moving trajectory indicated by the information of the two are greater than a threshold, it means that the terminal device B has strong correlation with the sensing target, and therefore, the terminal device A which interacts with the terminal device B also has strong correlation with the sensing target. It can be understood that in this scenario, the terminal device A is capable of obtaining the sensing information (such as the information of the sensing target) based on the signal sent by the terminal device B.

[0246] The second condition, the communication beam on the communication link, can be used for sensing.

[0247] It should be understood that if the communication beam of the communication link can be used for sensing, it means that the communication link is likely to provide sensing information.

[0248] For the currently measured link 1 (communication link), it can be determined whether the communication beam on the link 1 can be used for sensing, and if the communication beam on the link 1 can be used for sensing, it means that the link 1 is likely to provide sensing information.

[0249] The communication beams on the communication link described in the embodiments of the present application include a receiving communication beam and a transmitting communication beam, the transmitting communication beam represents a communication beam for transmitting a communication signal, and the receiving communication beam represents a communication beam for receiving a communication signal. When both the transmitting communication beam and the receiving communication beam of the communication link satisfy the second condition, it means that the link 1 can provide sensing information.

[0250] For the receiving communication beam on the link 1 (communication link), the first device determines whether the receiving communication beam on the link 1 is available for sensing.

[0251] For the transmitting communication beam on the link 1 (communication link), in an example, the communication node for transmitting a communication signal (such as the first network device in scenarios 1 and 2, the second terminal device in scenario 3, and the first terminal device in scenario 4) can determine whether the transmitting communication beam on the link 1 is available for sensing. In this way, the communication node for transmitting a communication signal determines that the transmitting communication beam of the link 1 is available for sensing, and then transmits a communication signal to the first device on the link 1. In this way, the first device can only need to determine whether the receiving communication beam of the link 1 is available for sensing, and if it is determined that the receiving communication beam is available for sensing, it means that the communication beams of the link 1 satisfy the second condition.

[0252] In another example, the first device can also determine whether the transmitting communication beam on the link 1 is available for sensing based on the information for sensing and the relevant information of the communication node for transmitting a communication signal (such as the network device A in scenarios 1 and 2, or the terminal device A in scenario 3). In this way, when both the transmitting communication beam and the receiving communication beam of the link 1 satisfy the second condition, it means that the communication beams of the link 1 satisfy the second condition. For example, the information for sensing can include information of a sensing target, information of a sensing area, and / or information of a transmitting sensing beam, etc., and the relevant information of the communication node for transmitting a communication signal can include information of the transmitting communication beam (such as the second communication beam described above) on the link 1, and position information of the communication node for transmitting a communication signal. For scenarios 1 and 2 described above, the first network device as the communication node for transmitting a communication signal can transmit the information of the sensing target, the information of the sensing area, and the information of the first sensing beam through the measurement assistance information described above.

[0253] In another example, in the scenario where the link 1 is the link between the first network device and the first device, the first network device sends measurement indication information to the first device to indicate the embodiment of the multiplexing measurement condition. The first device can determine whether the transmitting communication beam on the 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 defaulted that the transmitting communication beam on the link 1 is available for sensing.

[0254] In the embodiments of the present application, the following method can be used to determine whether the current measured link 1 (communication link) satisfies the second condition.

[0255] Method 1: determining whether the communication beam of link 1 satisfies the second condition according to the relationship between the communication beam of link 1 and the sensing target.

[0256] For the receiving communication beam of link 1, in some embodiments, the first device can determine whether the receiving communication beam of link 1 satisfies the second condition according to the sensing direction between the sensing target and the first device and the angle coverage range of the receiving 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. For example, the first network device can indicate the position of the sensing target by sending the information of the sensing target to the first device, and the information of the sensing target can be carried in the measurement assistance information of the measurement indication information.

[0257] For example, if the sensing direction between the sensing target and the first device is within the angle coverage range 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 sensing direction between the sensing target and the first device is outside the angle coverage range of the receiving communication beam of link 1, it means that the receiving communication beam of link 1 cannot be used for sensing.

[0258] In fact, the sensing direction between the sensing target and the first device can be compared to the beam pointing of the receiving sensing beam. If the sensing direction is within the angle coverage range of the receiving communication beam of link 1, it means that the receiving communication beam of link 1 is closer to the receiving sensing beam, so it can be considered that the receiving communication beam of link 1 can be used for sensing.

[0259] FIG. 11 is another schematic diagram of a communication scenario provided by the embodiments of the present application. Referring to (a) of FIG. 11, the sensing target direction between the sensing target and the terminal device A (an example of the first device) is within the angle coverage range of the receiving communication beam of the communication link A1 (an example of link 1), so the receiving communication beam of the communication link A1 satisfies the second condition. It should be noted that the receiving communication beam and the sensing direction shown in (a) of FIG. 11 are only simple schematic forms for understanding the scheme, and do not represent the actual form of the receiving communication beam and the sensing direction.

[0260] The angular coverage range of a received communication beam represents the area within which radiated energy is concentrated. For example, the angular coverage range of a received communication beam can be determined based on the beam direction and beamwidth, resulting in a coverage area within a certain angle centered on the beam direction and extending outwards at half the beamwidth. The explanations below regarding the angular coverage range of the transmitted communication beam, the transmitted sensing beam, and the received sensing beam are the same as those for the received communication beam, and will not be repeated hereafter.

[0261] In some embodiments, the receiving communication beam of link 1 can be determined based on information about the receiving communication beam of link 1. For example, the information about the receiving communication beam of link 1 includes beam identifier (such as beam ID), beam pointing, and beamwidth. In other embodiments, the receiving communication beam of link 1 can also be determined based on the parameters of the spatial filter that receives the communication signal on link 1.

[0262] Similarly, for the transmission beam of link 1, the first device or the communication node transmitting the communication signal can determine whether the transmission beam of link 1 satisfies the second condition based on the sensing direction between the sensing target and the communication node transmitting the communication signal and the angular coverage range of the transmission beam of link 1. If the sensing direction between the sensing target and the communication node transmitting the communication signal is within the angular coverage range of the transmission beam of link 1, it means that the transmission beam of link 1 can be used for sensing; if the sensing direction between the sensing target and the communication node transmitting the communication signal is outside the angular coverage range of the transmission beam of link 1, it means that the transmission beam cannot be used for sensing.

[0263] In some embodiments, the transmit communication beam of link 1 can be determined based on information about the transmit communication beam of link 1. For example, the information about the transmit communication beam of link 1 includes beam identifier (such as beam ID), beam pointing, and beamwidth. In other embodiments, the transmit communication beam of link 1 can also be determined based on the parameters of the spatial filter that transmits communication signals on link 1.

[0264] For a detailed 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.

[0265] Method 2: Determine whether the communication beam of link 1 satisfies the second condition based on the relationship between the communication beam of link 1 (communication link) and the sensing area.

[0266] For the receiving communication beam of the link 1, in some embodiments, the first device can determine whether the receiving communication beam of the link 1 satisfies a second condition according to an angle range between the sensing area and the first device and an angle coverage range of the receiving communication beam of the link 1. Wherein, the angle range between the sensing area and the first device is determined based on a position of the sensing area and a position of the first device, exemplarily, the first network device indicates the position of the sensing area by sending information of the sensing area to the first device, for example, the information of the sensing area can be carried in the measurement assistance information of the measurement indication information.

[0267] Exemplarily, if the angle range between the sensing area and the first device at least partially overlaps with the angle coverage range of the receiving communication beam of the link 1, it means that the receiving communication beam of the link 1 can be used for sensing; if the angle range between the sensing area and the first device does not overlap with the angle coverage range of the receiving communication beam of the link 1, it means that the receiving communication beam of the link 1 cannot be used for sensing. It should be understood that at least partial overlap described here and in the following means partial overlap or full overlap, where partial overlap means that the two angle ranges partially overlap, and full overlap can mean that the two angle ranges are the same, or one angle range includes the other angle range, such as the angle range between the sensing area and the first device including the angle coverage range of the receiving communication beam.

[0268] In fact, the angle range between the sensing area and the first device can be analogous to the angle coverage range of the receiving sensing beam, and in the case that the angle range between the sensing area and the first device at least partially overlaps with the angle coverage range of the receiving communication beam of the link 1, it means that the receiving communication beam of the link 1 is closer to the receiving sensing beam of the link 1, so it can be considered that the receiving communication beam of the link 1 can be used for sensing.

[0269] Please refer to (b) of FIG. 11, 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 the link 1) partially overlap, therefore, the receiving communication beam of the communication link A satisfies the second condition. It should be noted that the receiving communication beam and the angle range shown in (b) of FIG. 11 are only a simple schematic form for understanding the scheme, and do not represent the physically real receiving communication beam and angle range.

[0270] Similarly, for the transmitting communication beam of link 1, the first device or the communication node transmitting the communication signal can determine whether the transmitting communication beam of link 1 satisfies the second condition according to the angle range between the sensing region and the communication node transmitting the communication signal and the angle coverage of the transmitting communication beam of link 1. If the angle range between the sensing region and the communication node transmitting the communication signal at least partially overlaps with the angle coverage of the transmitting communication beam of link 1, it means that the transmitting communication beam can be used for sensing; if the angle range between the sensing region and the communication node transmitting the communication signal does not overlap with the angle coverage of the transmitting communication beam of link 1, it means that the transmitting communication beam cannot be used for sensing. The specific description of the transmitting communication beam of link 1 can refer to the related description of the receiving communication beam of link 1, and will not be described here.

[0271] In some embodiments, whether the communication beam of link 1 satisfies the second condition is determined according to the angle coverage of the communication beam of link 1 and the angle coverage of the sensing beam.

[0272] In some embodiments, whether the communication beam of link 1 satisfies the second condition is determined according to the angle coverage of the communication beam of link 1 and the angle coverage of the sensing beam.

[0273] In an example, if the angle coverage of the communication beam of link 1 at least partially overlaps with the angle coverage of the sensing beam, it means that the communication beam of link 1 can be used for sensing, and if the angle coverage of the communication beam of link 1 does not overlap with the angle coverage of the sensing beam, it means that the communication beam of link 1 cannot be used for sensing.

[0274] In another example, if the angle coverage of the communication beam of link 1 at least partially overlaps with the angle coverage of the sensing beam, and the overlapping range is greater than or equal to a range threshold value, it means that the communication beam of link 1 can be used for sensing, and vice versa, if the angle coverage of the communication beam of link 1 does not overlap with the angle coverage of the sensing 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 sensing.

[0275] In another example, if the angle coverage of the communication beam of link 1 at least partially overlaps with the angle coverage of the sensing beam, and the beamforming gain of the overlapping range is greater than or equal to a gain threshold value, it means that the communication beam of link 1 can be used for sensing, and vice versa, if the angle coverage of the communication beam of link 1 does not overlap with the angle coverage of the sensing 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 sensing.

[0276] For the receive communication beam of link 1, the first device determines whether the receive communication beam of link 1 satisfies a second condition according to the angular coverage of the receive communication beam of link 1 and the angular coverage of the receive sensing beam. For the transmit communication beam of link 1, the first device or the communication node transmitting the communication signal determines whether the transmit communication beam of link 1 satisfies the second condition according to the angular coverage of the transmit communication beam of link 1 and the angular coverage of the transmit sensing beam. The specific description about the transmit communication beam of link 1 can refer to the relevant description about the receive communication beam of link 1, and will not be repeated here.

[0277] The above is a specific description of the receive communication beam on link 1 and the transmit communication beam on link 1, which will not be repeated here.

[0278] Regarding the receive sensing beam, in some embodiments, the receive sensing beam can be determined based on the information of the receive sensing beam, for example, the information of the receive sensing beam includes beam identification (such as beam ID), beam pointing and beam width. In other embodiments, the receive sensing beam can also be determined based on the parameters of the spatial filter of the received sensing signal.

[0279] Regarding the transmit sensing beam, in some embodiments, the transmit sensing beam can be determined based on the information of the transmit sensing beam, for example, the information of the transmit sensing beam includes beam identification (such as beam ID), beam pointing and beam width. In other embodiments, the transmit sensing beam can also be determined based on the parameters of the spatial filter of the transmitted sensing signal.

[0280] The third condition is that the scatterer on the communication link is in the sensing area.

[0281] It should be understood that the third condition considers the scenario that the sensing target as shown in FIGS. 1 to 3 is a scatterer. If the scatterer on the communication link is in the sensing area, it means that the communication link is likely to provide sensing information.

[0282] For the currently measured link 1 (communication link), the first device can determine whether the scatterer on link 1 is in the sensing area. If the scatterer on link 1 is in the sensing area, it means that link 1 is likely to provide sensing information.

[0283] In an implementation, the first device determines the position of the scatterer on link 1, and then determines whether the scatterer is in the sensing area.

[0284] For the scenario shown in FIGS. 1-3, most of the scattering bodies on the communication link cause the multipath effect (or multipath phenomenon) of the signal. The multipath effect refers to the reflection, refraction, scattering, and other influences of electromagnetic waves in the process of propagation due to encountering different obstacles (such as buildings, hills, trees, etc.), resulting in multiple paths of the same signal reaching the receiving end. The signal components of the signal reaching the receiving end through each path are multipath components, and each multipath component has a phase difference and amplitude difference due to the difference in path length and propagation time, thereby interfering with each other to cause distortion or errors of the original signal.

[0285] For ease of description, the link in which the multipath effect occurs is referred to as a multipath link, and the multiple paths through which the same signal reaches the receiving end are referred to as multiple sub-links. The following explanations about the multipath link and the sub-link are the same as this place, and the following will not be repeated. In addition, the channel formed by the multiple paths can be referred to as a multipath channel.

[0286] FIG. 12 is a schematic diagram of the multipath effect provided by an embodiment of the present application. Referring to FIG. 12, the communication signal sent by the network device A reaches the terminal device A through two paths, which can also be referred to as two sub-links: sub-link 11 and sub-link 12. The sub-link 11 and the sub-link 12 form a link 1 for transmitting a complete communication signal, and the link 1 is a multipath link. The signal component reaching the terminal device A through the sub-link 11 is a multipath component 1, and the signal component reaching the terminal device A through the sub-link 12 is a multipath component 2. The multipath component 1 and the multipath component 2 are superimposed on each other at the terminal device A to form a signal received by the terminal device A, and the terminal device A processes the superimposed signal.

[0287] In the case where the communication signal has the multipath effect, in some embodiments, the first device can determine the position of the scattering body on the sub-link of the link 1 having the scattering body as the multipath link. As long as the scattering body of at least one sub-link (or multipath component) of the link 1 is located in the perception area, it is considered that the link 1 satisfies the third condition, and thus it can be determined that the link 1 is likely to provide perception information.

[0288] For the processing of the signal having the multipath effect, in order to better analyze and process the multipath effect, the signal can be processed in clusters, that is, the multipath components having similar characteristics are grouped into the same cluster. Here, the "cluster" refers to a group of multipath components that arrive close in time, have similar time delay and angle of arrival (AOA). The center position of each cluster is referred to as the cluster center position, which usually corresponds to the path with the maximum signal strength or the minimum time 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 in this area are relatively consistent.

[0289] Therefore, in some embodiments, the first device can calculate the cluster center position of each cluster of the plurality of clusters of the communication signal transmitted on the link 1, for each cluster with a scatterer, the cluster center position of each cluster is approximately the position of the scatterer, so as long as the cluster center position of at least one cluster in the cluster with the scatterer is located within the awareness area, it can be determined that at least one scatterer of the link 1 is located within the awareness area, and the link 1 satisfies the third condition. Continuing to take Figure 12 as an example, the communication signal transmitted on the link 1 has two clusters, and the cluster center position of one of the clusters is approximately the position of the scatterer, so it can be determined that one scatterer of the link 1 is located within the awareness area, and the link 1 satisfies the third condition.

[0290] In an example, the ratio of the overlapping area of the cluster center position area of the cluster with the scatterer and the awareness area to the minimum of the awareness area and the cluster center position area can be used to determine whether the scatterer is within the awareness area, such as (cluster center position area∩awareness area) / min(cluster center position area, awareness area), when the ratio of the overlapping area of the two and the minimum of the two is greater than a threshold, it can be considered that the scatterer is located within the awareness area.

[0291] In the embodiment of determining whether the link 1 satisfies the third condition, the first network device can send the information of the awareness area to the first device, the information of the awareness area including position information for indicating the position of the awareness area, for example, the information of the awareness area is carried in the measurement assistance information of the measurement indication information.

[0292] The fourth condition is that the distance between the communication node on the communication link and the center position of the awareness area is less than a first threshold, or the distance between the communication node on the communication link and the awareness target is less than a second threshold.

[0293] The fourth condition considers the distance between the communication node on the communication link and the awareness area (or the awareness target), the smaller the distance, the more likely it is that the communication link provides awareness information, and vice versa, the larger the distance, the less likely it is that the communication link provides awareness information.

[0294] 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 awareness area is less than the first threshold, for the first device of the link 1 (communication link), the first device determines whether the distance between itself and the center position of the awareness area is less than the first threshold, and in the case where the distance between the two is less than the first threshold, the link 1 satisfies the fourth condition. In some scenarios, the communication node is located within the awareness area, and the communication node may or may not be the awareness target.

[0295] Exemplarily, the first network device can send the information of the sensing area to the first device, the information of the sensing area comprising location information for indicating the location of the sensing area, for example, the information of the sensing area is carried in the measurement assistance information of the measurement indication information.

[0296] In the embodiment where the fourth condition is that the distance between the communication node of the communication link and the center location of the sensing target is less than the second threshold, for the first device of link 1 (the communication link), the first device determines whether the distance between itself and the center location of the sensing target is less than the second threshold, and in the case where 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 sensing target is almost 0, the communication node is the sensing target.

[0297] Exemplarily, the first network device can send the information of the sensing target to the first device, the information of the sensing target comprising location information for indicating the location of the sensing target, for example, the information of the sensing target is carried in the measurement assistance information of the measurement indication information.

[0298] In the above, each condition in the first type of conditions of the embodiments of the present application is described in detail. It should be understood that each condition of the first type of conditions in the above examples and the manner of link measurement based on each condition are only illustrative, and in implementation, more conditions and more manners can be used for link measurement, and the embodiments of the present application should not be limited in this way.

[0299] It should also be understood that each condition of the first type of conditions described above can have various combinations based on actual scenarios. For example, the first type of conditions can be a combination of one condition or more conditions other than the first condition. The first type of conditions can be a combination of one condition or more conditions other than the third condition.

[0300] Second type of conditions

[0301] As described above, the second type of conditions focuses on the characteristics of the communication channel of the communication link. Taking link 1 (the communication link) as an example, in the case where the currently measured link 1 satisfies the first type of conditions, it indicates that link 1 can provide sensing information, but if the channel condition of the communication channel of link 1 is not ideal, it will also affect the effect of sensing. Therefore, the second type of conditions can be further combined to measure the communication link.

[0302] 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. Hereinafter, taking the signal quality, Doppler shift and power of the communication signal as the parameters for evaluating the characteristics of the communication channel as an example, the second type of conditions is described in detail. It should be understood that other parameters for evaluating the characteristics of the communication channel can also be used as the basis for measuring the second type of conditions, and the embodiments of the present application are not limited in this way.

[0303] A fifth condition, a signal quality of the communication signal transmitted on the communication link is greater than or equal to a signal quality threshold.

[0304] It should be appreciated 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 sensing.

[0305] For the link 1 currently measured by the first device, the signal quality of the communication signal received on the link 1 is compared with the signal quality threshold, and 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 the link 1 is relatively ideal.

[0306] 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).

[0307] It should be appreciated 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 a threshold of SNR and a threshold of signal strength.

[0308] A sixth condition, a maximum Doppler shift of the communication signal transmitted on the communication link is less than or equal to a Doppler shift threshold.

[0309] The Doppler shift represents the fading rate of the channel. When a mobile station (such as a mobile phone, a communication device on a train, etc.) moves at a constant speed, due to the Doppler effect, the frequency of the received signal will change, and this change rate is the Doppler shift. In high-speed railway and other high-speed moving scenarios, the Doppler shift is particularly obvious, because it will directly affect the stability and reliability of the signal. Therefore, the Doppler shift can be used to measure the change rate of the channel, and if the change rate of the channel is too fast, it means that the channel is not suitable.

[0310] Therefore, for the link 1 currently measured by the first device, the maximum Doppler shift in the Doppler shift of the received communication signal on the link 1 is compared with the Doppler shift threshold, and if the maximum Doppler shift of the received communication signal is less than or equal to the Doppler shift threshold, it means that the channel condition of the communication channel of the link 1 is relatively ideal, which further increases the possibility that the link 1 can be used for sensing.

[0311] The seventh condition is that, in the case that the communication link is a multipath link, the power of each of the at least one sub-link of the communication link is greater than or equal to the power threshold, or the power ratio of the power of each of the at least one sub-link of the communication link to the power of the communication link is greater than or equal to the power ratio threshold.

[0312] It should be understood that the power of the sub-link described herein refers to the power of the received communication signal on the sub-link. The received communication signal on the sub-link can be referred to as a multipath component. For related explanations of multipath links and sub-links, please refer to the related description above.

[0313] It should also be understood that if the 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, which further increases the possibility that the communication link can be used for sensing.

[0314] For the link 1 currently measured by the first device, the power of each of the at least one sub-link of the link 1 is compared with the power threshold, and if the power of each of the at least one sub-link of the link 1 is greater than or equal to the power threshold, it means that the channel condition of the communication channel of the link 1 is relatively ideal; or the power ratio of the power of each of the at least one sub-link of the link 1 to the power of the link 1 is compared with the power ratio threshold, and if the power ratio of the power of each of the at least one sub-link of the link 1 to the power of the link 1 is greater than or equal to the power ratio threshold, it means that the channel condition of the communication channel of the link 1 is relatively ideal, which further increases the possibility that the link 1 can be used for sensing.

[0315] Taking the power ratio of the power of the sub-link to the power of the link as an example, for example, after the link 1 occurs multipath effect, 3 sub-links are formed, the first device measures the link 1, the sub-link 1 and the sub-link 2 satisfy the first condition, the power ratio of the power of the sub-link 1 to the power of the link 1 is greater than or equal to the power ratio threshold, and the power ratio of the power of the sub-link 2 to the power of the link 1 is greater than or equal to the power ratio threshold, so it can be considered that the link 1 satisfies the seventh condition. The power of the sub-link or the power ratio of the sub-link to the power of the link 1 can be determined by the channel gain of the sub-link.

[0316] The eighth condition, in the case that the communication link is a multipath link, the signal quality of the communication signal received on each of at least one sub-link of the communication link is greater than or equal to a signal quality threshold.

[0317] It should be understood that if the 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, further increasing the possibility that the communication link can be used for sensing.

[0318] For the link 1 currently measured by the first device, the link 1 is a multipath link, the signal quality of the communication signal received on each of the plurality of sub-links of the link 1 is compared with the signal quality threshold, and if the signal quality of the communication signal received on each of at least one sub-link of the link 1 is greater than or equal to the signal quality threshold, it means that the channel condition of the communication channel of the link 1 is relatively ideal, further increasing the possibility that the link 1 can be used for sensing.

[0319] Continuing with the above example of the link 1 including 3 sub-links, sub-link 1 and sub-link 2 satisfy the first type of condition, the signal quality of the communication signal received on sub-link 1 is greater than or equal to the signal quality threshold, and the signal quality of the communication signal received on sub-link 2 is greater than or equal to the signal quality threshold, so it can be considered that the link 1 satisfies the eighth condition. Among them, the signal quality of the sub-link can be determined by the sub-power or the power ratio of the sub-link to the link 1, and the power of the sub-link or the power ratio of the sub-link to the link 1 can be determined by the channel gain of the sub-link.

[0320] The ninth condition, in the case that the communication link is a multipath link, the maximum Doppler shift of the communication signal received on each of at least one sub-link of the communication link is less than or equal to a Doppler shift threshold.

[0321] It should be understood that if the 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, further increasing the possibility that the communication link can be used for sensing.

[0322] For the link 1 currently measured by the first device, the link 1 is a multipath link, the maximum Doppler shift in the Doppler shift of the communication signal received on each of the plurality of sub-links of the link 1 is compared with the Doppler shift threshold, if the maximum Doppler shift of the communication signal received on each of the at least one sub-link of the link 1 is less than or equal to the Doppler shift threshold, it means that the channel condition of the communication channel of the link 1 is relatively ideal, further increasing the possibility that the link 1 can be used for sensing. Continue to take the link 1 including 3 sub-links as an example in the above example, the maximum Doppler shift of the communication signal received on the sub-link 1 is less than or equal to the Doppler shift threshold, the maximum Doppler shift of the communication signal received on the sub-link 2 is less than or equal to the Doppler shift threshold, and thus it can be considered that the link 1 meets the ninth condition.

[0323] It should be understood that the above-mentioned seventh condition, eighth condition and ninth condition are applicable to the scenario that the communication link is a multipath link, and in the implementation, the first device selects the applicable condition to measure the link 1 based on the actual situation of the link 1.

[0324] The above describes each condition in the second type of condition of the embodiments of the present application in detail.

[0325] It should be understood that each condition of the above-mentioned second type of condition and the way of measuring the link based on each condition are only illustrative, and in the implementation, more conditions and more ways can be used for measuring the link, and the embodiments of the present application should not be limited.

[0326] The first device measures the link 1 (communication link) based on the multiplexing measurement condition, determines whether the link 1 can be used for sensing based on the measurement result obtained by the measurement, and sends a measurement report. In some embodiments, the first device sends or does not send a measurement report based on different situations of the measurement, and in the case of sending a measurement report, the sent measurement report is also different. In the case of sending a measurement report, the first device performs 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 is prohibited to send) a measurement report.

[0327] Next, taking the multiplexing measurement condition including the first type of condition and the second type of condition as an example, the specific content of whether the first device sends a measurement report and the measurement report is specifically described based on the measurement of the link 1 by the first device based on the multiplexing measurement condition.

[0328] FIG. 13 is a schematic flowchart of the process of measuring the link based on the multiplexing measurement condition to determine whether the communication link can be used for sensing according to the embodiments of the present application.

[0329] In the embodiment where the multiplexing measurement conditions include the first type of conditions and the second type of conditions, the first device has 3 cases (case 1, case 2 and case 3 below) of results based on the first type of conditions and the second type of conditions for measuring the link 1, and the first device performs different steps based on different cases.

[0330] Case 1, the link 1 (communication link) satisfies the first type of conditions and the second type of conditions

[0331] In the case where the first device determines that the link 1 (communication link) satisfies the first type of conditions and the second type of conditions, the first device determines that the link 1 is available for sensing, and thus the first device sends a measurement report of the link 1. The measurement report includes multiplexing indication information for indicating that the link 1 is available for sensing. Exemplarily, the multiplexing indication information can be acknowledgment (ACK) information. Thus, after the first network device receives the measurement report including the multiplexing indication information for indicating that the link 1 is available for sensing, the first network device can determine that the link 1 satisfies the first type of conditions and the second type of conditions.

[0332] Referring to FIG. 13, in an implementation, exemplarily, in step S131a, the first device determines whether the link 1 satisfies the first type of conditions. In the case where the link 1 satisfies the first type of conditions, in step S131b, the first device determines whether the link 1 satisfies the second type of conditions. In the case where the link 1 satisfies the second type of conditions, the first device determines that the link 1 is available for sensing, and correspondingly, the first device performs 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 the link 1 is available for sensing. Exemplarily, the multiplexing indication information can be ACK information.

[0333] It should be noted that the link 1 satisfying the first type of conditions means that the link 1 satisfies all conditions of the first type of conditions indicated by the measurement indication information, and the link 1 satisfying the second type of conditions means that the link 1 satisfies all conditions of the second type of conditions indicated by the measurement indication information.

[0334] In the above case 1, in some embodiments, the measurement report not only includes the multiplexing indication information (such as ACK information) for indicating that the link 1 is available for sensing, but also includes sensing assistance information, so that the first network device can further determine whether the link 1 satisfies the sensing requirement based on the sensing assistance information, to finally determine whether the link 1 is available for sensing. Here, the sensing requirement focuses on the measurement of the sensing task in the three dimensions of distance measurement, speed measurement and angle measurement. The main indicators of the sensing requirement include, for example, the indicators such as the unambiguous range, the resolution, the measurement accuracy and the channel variation rate. For specific description of the sensing requirement, reference can be made to the related description below, which is not described here in detail.

[0335] Exemplarily, the perception assistance information comprises at least one of the following information.

[0336] information of a receiving communication beam on the link 1 (denoted as a first communication beam), the receiving communication beam on the link 1 and the first communication beam are alternative descriptions of a communication beam receiving a communication signal on the link 1. Exemplarily, the information of the receiving communication beam on the link 1 can comprise a beam identifier (such as a beam ID), a beam width and a beam pointing direction.

[0337] first Doppler shift information, used for indicating a maximum Doppler shift and / or a Doppler spread of the communication signal received on the link 1.

[0338] first signal information, used for indicating a signal quality of the communication signal received on the link 1.

[0339] second signal information, in the case that the link 1 is a multipath link, the second signal information is used for indicating a signal quality of the communication signal received on a sub-link of the link 1 satisfying a multiplexing measurement condition. For example, after the multipath effect occurs on the link 1, 3 sub-links are formed, sub-link 1 and sub-link 2 satisfy the multiplexing measurement condition, and sub-link 3 does not satisfy the multiplexing measurement condition, the second signal information is used for indicating the signal quality of the communication signal received on the sub-link 1 and the sub-link 2. When indicating the signal quality of each sub-link, exemplarily, a differential manner can be adopted, and the differential reference can be a minimum value of the signal quality of the sub-links, or can be the signal quality of the communication signal received on the link 1, etc., which is not limited here.

[0340] power information, in the case that the link 1 is a multipath link, the power information is used for indicating a power ratio of a power of a sub-link of the link 1 satisfying a multiplexing measurement condition to a power of the link 1. Continuing the above example of the link 1 comprising 3 sub-links, the power information is used for indicating the power ratio of the power of the sub-link 1 to the power of the link 1 and the power ratio of the power of the sub-link 2 to the power of the link 1, or the power information is used for indicating the power ratio of the sum of the power of the sub-link 1 and the power of the sub-link 2 to the power of the link 1.

[0341] second Doppler shift information, in the case that the link 1 is a multipath link, the second Doppler shift information is used for indicating a Doppler shift of the communication signal received on a sub-link of the link 1 satisfying a multiplexing measurement condition. Continuing the above example of the link 1 comprising 3 sub-links, the second Doppler shift information is used for indicating the Doppler shift of the communication signal received on the sub-link 1 and the sub-link 2.

[0342] In the case that the link 1 is a multipath link, the second signal information can be obtained by the first signal information and the power information. Therefore, in the case that the 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 in an alternative manner to determine the signal quality of the communication signal received on the link satisfying the multiplexing measurement condition in the link 1.

[0343] It should be noted that, in addition to the information of the received communication beam on the link 1 (denoted as the first communication beam), the type of the information included in the perception assistance information is related to the type of the condition included in the second type of condition. For example, the second type of condition includes the fifth condition to the ninth condition, and in the case that the link 1 is a multipath link, the perception assistance information at least includes the second signal information and the second Doppler shift information, or the perception assistance information includes the first signal information, the power information and the second Doppler shift information, and the perception assistance information can also exemplarily include the first signal information and the first Doppler shift information. For another example, the second type of condition includes the fifth condition to the ninth condition, and in the case that the link 1 is not a multipath link, the perception assistance information includes the first signal information and the first Doppler shift information.

[0344] It should be further noted that, for the link 1 measured by the first device, in the case that the link 1 is a multipath link, the multipath components received by the first device from each sub-link (or multiple paths) are superimposed to form a received communication signal, and the first device measures the link 1 as a whole through the superimposed communication signal, and the measurement result of each sub-link can be obtained. For example, as long as at least one sub-link in the measured link 1 satisfies the multiplexing measurement condition, it is considered that the link 1 can be used for perception, and the related information of the sub-link satisfying the condition is reported.

[0345] Case 2, the link 1 (communication link) satisfies the first type of condition and does not satisfy the second type of condition

[0346] In the case that the first device determines that the link 1 (communication link) satisfies the first type of condition and does not satisfy the second type of condition, it means that the spatial domain resource of the link 1 can be used for perception, but the channel condition of the communication channel does not satisfy the condition, therefore, the first device determines that the link 1 cannot be used for perception, and thus the first device sends a measurement report including multiplexing indication information for indicating that the link 1 cannot be used for perception, and the multiplexing indication information can exemplarily be negative acknowledgment (NACK) information. Thus, after the first network device receives the measurement report including the multiplexing indication information for indicating that the link 1 cannot be used for perception, it can be determined that the link 1 cannot be used for perception, and more specifically, it can be determined that the link 1 satisfies the first type of condition and does not satisfy the second type of condition, i.e., it is determined that the channel condition of the communication channel of the link 1 does not satisfy the condition.

[0347] Referring to FIG. 13, in an implementation, exemplarily, in step S131a, the first device determines whether the link 1 satisfies the first type of condition, in the case where the link 1 satisfies the first type of condition, in step S131b, the first device determines whether the link 1 satisfies the second type of condition, in the case where the link 1 does not satisfy the second type of condition, the first device determines that the link 1 is not available for sensing, correspondingly, the first device performs step S1312, in step S1312, the first device sends a measurement report to the first network device, the measurement report includes multiplexing indication information for indicating that the link 1 is not available for sensing, for example, the multiplexing indication information can be NACK information.

[0348] It should be noted that the link 1 does not satisfy the second type of condition means that the link 1 does not satisfy at least one condition of the second type of condition. For example, taking the second type of condition includes the fifth condition and the sixth condition as an example, if the link 1 does not satisfy at least one of the fifth condition and the sixth condition, it is considered that the link 1 does not satisfy the second type of condition.

[0349] Case 3, the link 1 (communication link) does not satisfy the first type of condition

[0350] In the case where the first device determines that the link 1 (communication link) does not satisfy the first type of condition, it means that the link 1 cannot provide sensing information, therefore, the first device can determine that the link 1 is not available for sensing in the case where the link 1 does not satisfy the first type of condition, thus, exemplarily, the first device does not send a measurement report. In the case where the first network device does not receive the measurement report within a preset time length, it can be determined that the link 1 is not available for sensing, more specifically, it is determined that the link 1 does not satisfy the first type of condition.

[0351] Referring to FIG. 13, in an implementation, exemplarily, in step S131a, the first device determines whether the link 1 satisfies the first type of condition, in the case where the link 1 does not satisfy the first type of condition, the first device does not send a measurement report.

[0352] It should be noted that the link 1 does not satisfy the first type of condition means that the link 1 does not satisfy at least one condition of the first type of condition. For example, taking the first type of condition includes the second condition, the third condition and the fourth condition as an example, if the link 1 does not satisfy at least one of the three conditions, it is considered that the link 1 does not satisfy the first type of condition.

[0353] In the above step (such as step S1311 or step 1312) of sending the measurement report by the first device, in some other embodiments, the measurement report not only includes multiplexing indication information for indicating whether the link 1 is available for sensing, but also can include measurement results obtained by measuring the link 1, and the embodiments of the present application do not make any limitation.

[0354] In an example, the measurement result of the link 1 includes a result corresponding to each condition based on the measurement of the condition, and each condition corresponding result can include a measurement value. For example, each condition corresponding result further includes indication information indicating whether the link 1 meets the condition. In another example, the measurement result includes indication information indicating at least one condition met by the link 1, and can further include a measurement value corresponding to each condition in the at least one condition.

[0355] In step S140, the first network device determines the scheduling policy of the resource of the link 1.

[0356] In this step, the first network device determines the scheduling policy of the resource of the link 1 based on the measurement of the link 1 by the first device. Hereinafter, the scheduling policy of the resource of the link 1 is described based on the above three cases.

[0357] Scheduling policy of case 1

[0358] With reference back to 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 indicating that the link 1 is aware of the multiplexing, such as ACK information. In some embodiments, the measurement report further includes sensing assistance information.

[0359] In step S141, the first network device determines whether the link 1 meets the sensing requirement according to the received measurement report.

[0360] In the above case 1, the first network device receives the measurement report, obtains the multiplexing indication information and the sensing assistance information, and determines that the link 1 can be used for sensing according to the multiplexing indication information, and further determines whether the link 1 meets the sensing requirement according to the sensing assistance information. For specific description of the sensing assistance information, please refer to the related description of the sensing assistance information in case 1 above, which will not be repeated here.

[0361] It should be understood that although the result of the measurement of the link 1 by the first device based on the multiplexing measurement condition is that the link 1 can be used for sensing, the multiplexing measurement condition considers more the characteristics of the channel and whether the spatial resource is available, and does not consider whether the link 1 meets the sensing requirement. It can be understood that if the link 1 does not meet the sensing requirement, the sensing result obtained by sensing the sensing target is actually not up to the requirements, and thus the link 1 is ultimately not available for sensing.

[0362] In some embodiments, the main indicators of the sensing requirement include, but are not limited to, an unambiguous range, a resolution, a measurement accuracy, a channel variation rate, and the like. Exemplarily, the sensing requirement includes at least one of the following: the unambiguous range is within a preset range; the resolution is greater than or equal to a resolution threshold; the measurement accuracy is greater than or equal to a measurement accuracy threshold; and the channel variation rate meets a requirement.

[0363] The sensing requirement focuses on the measurement of the sensing task in three dimensions of distance measurement, speed measurement, and angle measurement.

[0364] Exemplarily, the unambiguous range can include an unambiguous range of speed (abbreviated as unambiguous speed range), an unambiguous range of distance (abbreviated as unambiguous distance range), and an unambiguous range of angle (abbreviated as unambiguous angle range), and correspondingly, the preset range includes a speed preset range, a distance preset range, and an angle preset range.

[0365] Exemplarily, the resolution includes a speed resolution, a distance resolution, and an angle resolution, and correspondingly, the resolution threshold includes a speed resolution threshold, a distance resolution threshold, and an angle resolution threshold.

[0366] Exemplarily, the measurement accuracy includes a speed measurement accuracy, a distance measurement accuracy, and an angle measurement accuracy, and correspondingly, the measurement accuracy threshold includes a speed measurement accuracy threshold, a distance measurement accuracy threshold, and an angle measurement accuracy threshold.

[0367] In this way, the first network device determines the values of the indicators related to the sensing requirement according to the sensing assistance information, compares the values of the indicators with the corresponding thresholds, and finally determines that the link 1 can be used for sensing in a case where the values of the indicators all meet the corresponding thresholds, and finally determines that the link 1 cannot be used for sensing in a case where at least one of the values of the indicators does not meet the corresponding threshold. For example, the sensing requirement includes the four items in the above example, and therefore, the unambiguous range, the resolution, the measurement accuracy, and the channel variation rate for sensing on the link 1 are determined based on the sensing assistance information. In a case where the unambiguous 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 variation rate meets the requirement, it is finally determined that the link 1 can be used for sensing, and otherwise, in a case where at least one of the unambiguous range, the resolution, and the measurement accuracy does not meet the corresponding threshold, it is finally determined that the link 1 cannot be used for sensing.

[0368] Taking the sensing mode of A-to-B as an example.

[0369] As to the resolution, exemplarily, the range resolution can be determined according to the bandwidth and the bistatic angle, the velocity resolution can be determined according to the wavelength, the sensing symbol period, the sensing symbol number, etc., and the angle resolution can be determined according to the wavelength and the aperture of the array. The bandwidth and the wavelength can be determined according to the frequency domain information of the link 1, the bistatic angle can be determined according to the information of the receiving communication beam (the first communication beam) on the link 1 and the information of the transmitting communication beam on the link 1, and the sensing symbol period and the sensing symbol number can be determined according to the time domain information of the link 1.

[0370] As to the unambiguous range, exemplarily, the unambiguous range of the distance can be determined according to the frequency domain sampling interval of the communication signal and the bistatic angle, the unambiguous range of the velocity can be determined according to the wavelength, the communication signal period and the bistatic angle, and the unambiguous range of the angle can be determined according to the wavelength and the antenna interval. The frequency domain sampling interval and the wavelength can be determined according to the frequency domain information of the link 1.

[0371] As to the measurement accuracy, exemplarily, the range measurement accuracy can be determined according to the range resolution and the SNR, the velocity measurement accuracy can be determined according to the velocity resolution and the SNR, and the angle measurement accuracy can be determined according to the angle resolution and the SNR. The SNR can be determined according to the first signal information, or the second signal information, or the first signal information and the power information, depending on whether the link 1 has the multipath effect.

[0372] As to the channel variation rate, the first Doppler shift information or the second Doppler shift information is used.

[0373] The specific process of determining the resolution, the unambiguous range, the measurement accuracy and the channel variation rate can refer to the description of the related art, which will not be repeated here.

[0374] In the above process, when the link 1 meets the first type of condition and the second type of condition, the process of further determining whether the link 1 meets the sensing requirement is actually a process of further measuring the link 1, and determining whether the link 1 meets the sensing requirement by the first network device can effectively reduce the power consumption of the terminal device and the signaling overhead of the air interface in the scenario where the first device is a terminal device.

[0375] In a case (denoted as Case 1.1) that it is determined based on step S141 that the link 1 satisfies the sensing requirement, it can be finally determined that the link 1 can be used for sensing, and thus, in step S1421, the first network device determines that the scheduling policy of the resource of the link 1 is scheduling policy 1. The scheduling policy 1 is used to indicate that the communication resource of the link 1 can be used for sensing. In this way, the communication resource of the link 1 can actually be used as a communication-sensing resource, and when sensing is performed, sensing can be performed based on the transmission of a communication signal on the communication resource of the link 1. Thus, since the communication resource of the link 1 can be used not only for communication but also for sensing, it is not necessary to configure additional sensing resource, and thus, the resource utilization rate can be effectively improved, and the wireless resource can be maximally utilized.

[0376] In a case (denoted as Case 1.2) that it is determined based on step S141 that the link 1 does not satisfy the sensing requirement, it can be finally determined that the link 1 cannot be used for sensing, and thus, in step S1422, the first network device determines that the scheduling policy of the resource of the link 1 is scheduling policy 2. The scheduling policy 2 is used to indicate that the sensing resource and the communication resource of the link 1 are orthogonal in the time domain and / or the frequency domain.

[0377] It can be understood that since it is finally determined that the link 1 cannot be used for sensing, but the link 1 satisfies the first type of condition and the second type of condition, it means that the related sensing resource and the communication resource of the link 1 can at least overlap in the spatial domain, but if the related sensing resource and the communication resource of the link 1 overlap in the time domain and the frequency domain, the sensing and the communication will interfere with each other, and thus, it is necessary to make the sensing resource and the communication resource of the link 1 orthogonal in the time domain and / or the frequency domain to avoid interference.

[0378] Scheduling policy of Case 2

[0379] Referring to FIG. 13, in Case 2, in step S1312, the first device sends the measurement report to the first network device, and correspondingly, the first network device receives the measurement report. The measurement report includes multiplexing indication information used to indicate that the link 1 cannot be used for sensing, such as NACK information.

[0380] Based on the multiplexing indication information in the received measurement report, the first network device can determine that the link 1 cannot be used for sensing, and more specifically, can determine that the link 1 satisfies the first type of condition and does not satisfy the second type of condition, i.e., determines that the channel condition of the link 1 is not ideal. In this way, the related sensing resource and the communication resource of the link 1 can overlap in the spatial domain, but if the related sensing resource and the communication resource of the link 1 overlap in the time domain and the frequency domain, the sensing and the communication will interfere with each other, and thus, it is necessary to make the sensing resource and the communication resource of the link 1 orthogonal in the time domain and / or the frequency domain to avoid interference.

[0381] Therefore, in step S1422, the first network device determines that the scheduling policy of the resource of link 1 is scheduling policy 2. The specific description of scheduling policy 2 can be referred to the related description above, and will not be described herein again.

[0382] Scheduling policy of case 3

[0383] Referring to FIG. 13, in case 3, the first device does not send (or is prohibited to send) the measurement report, and correspondingly, the first network device does not receive the measurement report. Therefore, without the special case, the first network device can determine that link 1 is not available for sensing in the case that the measurement report is not received, and more specifically, can determine that link 1 does not satisfy the first type of condition, i.e., the spatial domain resource of link 1 is not available for sensing. In this way, the related sensing resource is orthogonal to the communication resource of link 1 in the spatial domain, which means that the two can overlap or not overlap in the time domain and the frequency domain, and do not affect each other.

[0384] Therefore, in step S1423, the first network device determines that the scheduling policy of the resource of link 1 is scheduling policy 3. The scheduling policy 3 is used to indicate that the sensing resource and the communication resource of link 1 do not affect each other in the time domain and / or the frequency domain. It should be understood that the not affecting each other here means that the sensing resource and the communication resource of link 1 can overlap or not overlap in the time domain and / or the frequency domain.

[0385] It should be understood that the process of determining the scheduling policy of the resource of link 1 by the first network device in the above example is only illustrative.

[0386] In other embodiments, when the first network device determines the scheduling policy based on the received measurement report, it can also not need to further determine whether link 1 satisfies the sensing requirement, i.e., skip step S141, and directly determine the scheduling policy based on the multiplexing indication information in the measurement report. Specifically, in the case that the multiplexing indication information in the measurement report is used to indicate that link 1 is available for sensing, the first network device directly determines that the scheduling policy of the resource of link 1 is scheduling policy 1.

[0387] Combining FIG. 13 with FIG. 9, step S131 of FIG. 9 includes step S1311 or step S1312 of FIG. 13, and step S140 of FIG. 9 includes step S1421, step S1422 or step S1423 of FIG. 13, and the logical relationship between the respective steps is subject to the inherent logical relationship.

[0388] In step S150, the first network device sends the scheduling information.

[0389] In this step, the first network device determines and sends the scheduling information based on the determined scheduling policy of the communication resource of link 1. The scheduling information indicates the scheduled resource (denoted as resource 1), and the resource 1 includes at least one of the following resources: only sensing resource, only communication resource, and communication sensing resource.

[0390] Here, the only sensing resource, the only communication resource, and the communication sensing resource refer to the type of the resource.

[0391] The only sensing resource refers to the resource used only for sensing, the only communication resource refers to the resource used only for communication, and the communication sensing resource refers to the resource used for both communication and sensing. In addition, the only sensing resource, the only communication resource, and the communication sensing resource all involve time domain, frequency domain, and space domain. For example, the only sensing resource used only for sensing means that the resource collectively acts in the time domain, the frequency domain, and the space domain and is used only for sensing; and the communication sensing resource means that the resource collectively acts in the time domain, the frequency domain, and the space domain and is used for both communication and sensing.

[0392] In some embodiments, the scheduling information schedules the resource (i.e., sensing resource) used for sensing. Thus, the resource 1 has three possible cases: the resource 1 includes only the sensing resource, the resource 1 includes both the sensing resource and the communication sensing resource, or the resource 1 includes the communication sensing resource. The resource 1 includes both the sensing resource and the communication sensing resource means that a part of the resource 1 is the sensing resource and another part of the resource 1 is the communication sensing resource.

[0393] In other embodiments, the scheduling information schedules the resource (i.e., communication resource) used for communication. Thus, the resource 1 has three possible cases: the resource 1 includes only the communication resource, the resource 1 includes both the communication resource and the communication sensing resource, or the resource 1 includes the communication sensing resource.

[0394] The first network device is a device for determining resource scheduling. In the process of resource scheduling, the first network device not only performs resource scheduling on the first device based on the determined scheduling policy of the resource of the link 1, but also performs resource scheduling 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 policy determined based on the link measurement, and the two are not absolutely related. However, it can be understood that the scheme for measuring the communication link based on the multiplexing measurement condition to determine whether the communication resource of the link is used for sensing in the embodiments of the present application can provide a multiplexing basis for the scheduling of the communication and sensing resources, that is, the first network device can schedule the communication and sensing resources based on the result of measuring the communication link. In this way, the resource finally scheduled for the first device by the first network device may include multiplexed communication and sensing resources. In this way, the utilization rate of the resources can be improved to maximize the use of wireless resources, thereby improving the system performance, while the communication and sensing can be performed as much as possible.

[0395] For example, the scheduling policy for the resource of the link 1 is scheduling policy 1, that is, the communication resource of the link 1 can be used for sensing, that is, without considering other factors, the communication resource of the link 1 can actually be used as a communication and sensing resource for communication and sensing. However, in combination with the scheduling of the resources of other devices connected to the first network device, or in combination with the measurement result of other links, the resource 1 scheduled for the first device does not necessarily include the communication resource of the link 1, and even if the resource 1 includes the communication resource of the link 1, the communication resource of the link 1 is not necessarily used for sensing.

[0396] Since the case of resource multiplexing is considered, in order to facilitate the distinction between the functions of different resources, the embodiments of the present application also make related designs on the scheduling information.

[0397] In some embodiments, the scheduling information is used to indicate the function of the resource 1. Specifically, the resource 1 is only used for communication, or the resource 1 is only used for sensing, or at least part of the resource 1 is used for communication and sensing.

[0398] In the case that at least part of the resources of the resource 1 is used for communication and sensing, it means that part of the resources of the resource 1 or all of the resources of the resource 1 is used for sensing and communication, and the resources of the resource 1 used for sensing and communication are communication-sensing resources. In the case that part of the resources of the resource 1 is used for sensing and communication, another part of the resources of the resource 1 is used for sensing only or used for communication only. For example, in the case that the scheduling information schedules sensing resources, the resource 1 can include two parts of resources, one part of the resources is sensing-only resources used for sensing only, and the other part of the resources is communication-sensing resources used for sensing and communication. For another example, in the case that the scheduling information schedules communication resources, the resource 1 can include two parts of resources, one part of the resources is communication-only resources used for communication only, and the other part of the resources is communication-sensing resources used for sensing and communication. In the case that all of the resources of the resource 1 is used for sensing and communication, the whole of the resource 1 is communication-sensing resources.

[0399] Exemplarily, the scheduling information indicates the purpose of the resource 1 in the following manners.

[0400] Manner A

[0401] In the manner A, the scheduling information includes purpose information used for determining the three functions of the resource 1: the resource 1 is used for communication only, or the resource 1 is used for sensing only, or at least part of the resources of the resource 1 is used for communication and sensing.

[0402] In some embodiments, the purpose information includes 2 bits, and different values of the 2 bits can be used to directly indicate the function of the resource 1.

[0403] The 2 bits can represent 4 values of binary: 00, 01, 10 and 11, and therefore, any 3 values of the 4 values can be used to represent the three functions of the resource 1. For example, 01 represents sensing only, 10 represents communication only, and 11 represents sensing and communication. For another example, 01 represents sensing only, 10 represents communication only, and 11 represents sensing and communication.

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

[0405] In the case that the resource 1 scheduled by the scheduling information includes communication-only resources, the purpose information is used to indicate that the resource 1 is used for communication only.

[0406] In the case that the resource 1 scheduled by the scheduling information includes communication-only resources and communication-sensing resources, or includes sensing-only resources and communication-sensing resources, or includes communication-sensing resources, the purpose information is used to indicate that at least part of the resources of the resource 1 is used for communication and sensing.

[0407] In some embodiments, the target information includes 1 bit, and different values of the 1 bit can be used to determine the function of the resource 1.

[0408] In an example, in the embodiment where the scheduling information schedules the communication resource, for the resource 1 currently scheduled by the scheduling information, 1 (or 0) is used to indicate that the resource 1 is available for sensing, and 0 (or 1) is used to indicate that the resource 1 is unavailable for sensing. Thus, when 1 (or 0) is used to indicate that the resource 1 is available for sensing, it means that the resource 1 is not only used for communication, but also can be used for sensing, that is, it can be determined that at least part of the resource 1 is used for sensing and communication, that is, at least part of the resource 1 is a communication-sensing resource, in which case, the resource 1 has two possible cases, the resource 1 includes only a communication resource and a communication-sensing resource, or the resource 1 includes a communication-sensing resource. When 0 (or 1) is used to indicate that the resource 1 is unavailable for sensing, it can be determined that the resource 1 is only used for communication, in which case, the resource 1 includes only a communication resource.

[0409] In another example, in the embodiment where the scheduling information schedules the sensing resource, for the resource 1 currently scheduled by the scheduling information, 1 (or 0) is used to indicate that the resource 1 is available for communication, and 0 (or 1) is used to indicate that the resource 1 is unavailable for communication. Thus, when 1 (or 0) is used to indicate that the resource 1 is available for communication, it means that the resource 1 is not only used for sensing, but also can be used for communication, that is, at least part of the resource 1 is used for sensing and communication, that is, at least part of the resource 1 is a communication-sensing resource, in which case, the resource 1 has two possible cases, the resource 1 includes only a sensing resource and a communication-sensing resource, or the resource 1 includes a communication-sensing resource. When 0 (or 1) is used to indicate that the resource 1 is unavailable for communication, it can be determined that the resource 1 is only used for sensing, in which case, the resource 1 includes only a sensing resource.

[0410] In some embodiments, when the destination information indicates that at least part of the resource 1 is used for sensing and communication, the granularity of the resource associated with the destination information can be the entire resource scheduled by the scheduling information (i.e., the resource 1). For example, the value of 2 bits in the destination information indicates that the resource 1 is used for sensing and communication, and the resource associated with the destination information is the resource 1, without specifically associating to the specific location of the communication sensing resource in the resource 1 used for sensing and communication. The first device can determine that at least part of the resource 1 is used for sensing and communication based on the destination information, but cannot determine the specific location of the communication sensing resource in the resource 1 used for sensing and communication. Thus, when the first device determines that at least part of the resource 1 is used for sensing and communication based on the destination information, the first device can also determine the specific location of the communication sensing resource in the resource 1 based on other resources scheduled by the network device. For example, the scheduling information schedules a sensing resource, and the first device determines that at least part of the resource 1 is used for sensing and communication based on the destination information, and can also determine the overlapping resource of the other communication resource scheduled before and the resource 1 based on the other communication resource scheduled before and the resource 1 currently scheduled, the overlapping resource is the communication sensing resource in the resource 1, the non-overlapping resource is the sensing-only resource in the resource 1, and if the overlapping resource is the entire resource 1, it means that the entire resource 1 is the communication sensing resource. For another example, the scheduling information schedules a communication resource, and the first device determines that at least part of the resource 1 is used for sensing and communication based on the destination information, and can also determine the overlapping resource of the other sensing resource scheduled before and the resource 1 based on the other sensing resource scheduled before and the resource 1 currently scheduled, the overlapping resource is the communication sensing resource in the resource 1, the non-overlapping resource is the communication-only resource in the resource 1, and if the overlapping resource is the entire resource 1, it means that the entire resource 1 is the communication sensing resource. It should be understood that the overlapping resource described herein refers to the resource overlapping in the time domain, the frequency domain, and the spatial domain.

[0411] When the destination information indicates that at least part of the resource scheduled by the scheduling information is used for sensing and communication, since the granularity of the resource associated with the destination information is the entire resource scheduled by the scheduling information (i.e., the resource 1), it is not necessary to indicate the specific location of the communication sensing resource, which can effectively reduce the design complexity of the scheduling information and facilitate implementation.

[0412] In other embodiments, the granularity of the resource associated with the destination information can be the communication sensing resource in the resource 1 scheduled by the scheduling information, so that the first device can determine which resource in the resource 1 is the communication sensing resource based on the destination information.

[0413] In the above embodiments, the destination information in the scheduling information indicates the function of the resource 1, so that the first device can determine how to use the resource 1, and the implementation complexity is low, only one field in the scheduling information needs to be added to represent the destination information.

[0414] Mode B

[0415] In Mode B, different radio network temporary identities (RNTIs) can be used to correspond to different functions of the resource, so that different functions of the resource 1 can be determined according to different RNTIs. The RNTI is used to scramble the downlink control information (DCI).

[0416] In an example, the sensing corresponds to RNTI1, the communication corresponds to RNTI2, and the sensing and the communication correspond to RNTI3.

[0417] In this way, the first device can determine, based on the RNTI of the DCI carrying the scheduling information, whether the resource scheduled by the scheduling information is used only for sensing, only for communication, or at least part of the resource is used for sensing and communication. For ease of description, the DCI carrying the scheduling information for indicating the resource 1 is denoted as DCI1.

[0418] When the RNTI of the DCI1 carrying the scheduling information is RNTI1, the first device can determine that the currently scheduled resource 1 is used only for sensing, which is a sensing-only resource.

[0419] When the RNTI of the DCI1 carrying the scheduling information is RNTI2, the first device can determine that the currently scheduled resource 1 is used only for communication, which is a communication-only resource.

[0420] In the case that the RNTI of the DCI 1 carrying the scheduling information is RNTI 3, the first device can determine that at least part of the currently scheduled resource 1 is used for communication and sensing, and the resource 1 includes a communication-sensing resource. In an implementation, regardless of whether part of the resource 1 or the whole resource 1 is used for sensing and communication, the DCI is scrambled by RNTI 3, and the first device determines that at least part of the currently scheduled resource 1 is used for sensing and communication based on RNTI 3, and can further determine the specific location of the communication-sensing resource in the resource 1 based on other resources scheduled by the network device. For example, the scheduling information schedules a sensing resource, the first device determines that at least part of the resource 1 is used for sensing and communication based on RNTI 3, and can further determine, based on other communication resources scheduled before and the currently scheduled resource 1, the resource that overlaps with the resource 1, and the overlapping resource is the communication-sensing resource of the resource 1, and the non-overlapping resource is the sensing-only resource of the resource 1. If the overlapping resource is the whole resource 1, it means that the whole resource 1 is the communication-sensing resource. For another example, the scheduling information schedules a communication resource, the first device determines that at least part of the resource 1 is used for sensing and communication based on RNTI 3, and can further determine, based on other sensing resources scheduled before and the currently scheduled resource 1, the resource that overlaps with the resource 1, and the overlapping resource is the communication-sensing resource of the resource 1, and the non-overlapping resource is the communication-only resource of the resource 1. If the overlapping resource is the whole resource 1, it means that the whole resource 1 is the communication-sensing resource.

[0421] In the above embodiment, the function of the resource 1 scheduled by the scheduling information is indicated by the RNTI of the DCI carrying the scheduling information, and the signaling overhead can be reduced without the need to add additional information or fields.

[0422] In some embodiments, the scheduling information can further include priority information, and in the case that at least part of the resource 1 overlaps with other resources in the time domain and the frequency domain, the priority information is used to indicate that the at least part of the resource 1 preferentially carries a communication signal or preferentially carries a sensing signal, wherein the resource 1 is a sensing resource, and the other resource is a communication resource, or the resource 1 is a communication resource, and the other resource is a sensing resource.

[0423] Exemplarily, 1 (or 0) is used to represent preferentially carrying a communication signal, and 0 (or 1) is used to represent preferentially carrying a sensing signal.

[0424] It should be understood that the priority information herein refers to the case where at least part of the resources currently scheduled overlap (or conflict) in time domain and frequency domain with other resources, and the communication signal or the sensing signal needs to be carried on the resources overlapping in time domain and frequency domain with priority. It should also be understood that the at least part of the resources overlapping in time domain and frequency domain with other resources are resources that cannot be multiplexed, i.e., the at least part of the resources are not communication-sensing resources, but only sensing resources or only communication resources.

[0425] Taking the resources for sensing scheduled by the scheduling information as an example, i.e., the resource 1 is a sensing resource, in one case, the resource 1 includes only sensing resources and communication-sensing resources, the first part of the resource 1 is only sensing resources, and the second part of the resource 1 is communication-sensing resources. When the first part of the resources (part of the resource 1) overlaps in time domain and frequency domain with the communication resources, the priority information specifically indicates that the first part of the resources carries the communication signal or the sensing signal with priority. When the priority information indicates that the communication signal is carried with priority, sensing is not performed on the first part of the resources, and when the priority information indicates that the sensing signal is carried with priority, sensing is performed using the first part of the resources. In another case, the resource 1 includes only sensing resources, and all resources of the resource 1 are only sensing resources. When the resource 1 (all resources of the resource 1) overlaps in time domain and frequency domain with the communication resources, the priority information specifically indicates that the resource 1 carries the communication signal or the sensing signal with priority. When the priority information indicates that the communication signal is carried with priority, sensing is not performed on the resource 1, and when the priority information indicates that the sensing signal is carried with priority, sensing is performed using the resource 1.

[0426] In a wireless system, if the first network device dynamically configures the first device, it will cause a large network overhead, waste network resources, and increase the overall implementation complexity. Therefore, in order to reduce the signaling overhead and resource waste, and to minimize the resource scheduling signaling of the first device, in some embodiments, when the resource 1 scheduled by the scheduling information includes communication-sensing resources, the scheduling information can also determine other resources for communication and sensing.

[0427] In an example, the scheduling information includes channel indication information for indicating at least one communication channel available for sensing, wherein the at least one communication channel has the same beamforming as a communication channel (denoted as communication channel 1) of the communication-sensing resources of the resource 1. In this way, based on the channel indication information, at least one communication channel available for sensing can be determined.

[0428] Beamforming is a signal processing technique that uses an array of sensors to direct the transmission and reception of signals. It achieves beam focusing, deflection and shape control by adjusting the parameters of the basic units of the phased array so that signals at certain angles obtain constructive interference while signals at other angles obtain destructive interference. Beamforming includes digital beamforming and analog beamforming. Digital beamforming is a beamforming technique implemented in the digital baseband processing stage, which processes antenna weights in the baseband module and has high precision and flexibility. It forms a beam pointing to a specific direction by adjusting the phase and amplitude of each antenna transmitting or receiving signal in the digital domain. Among them, digital beamforming includes precoding codebook. Analog beamforming is a beamforming technique implemented in the analog baseband processing stage, which processes radio frequency signal weights and adjusts antenna phase through a phase shifter. Among them, analog beamforming includes spatial filter.

[0429] In the embodiments of the present application, the communication channel 1 of the communication-aware resource of the resource 1 has the same beamforming as the at least one communication channel, which means that both have the same digital beamforming and analog beamforming, more specifically, both have the same precoding codebook and spatial filter. It can be understood that the characteristics of the communication channels with the same beamforming are relatively close or similar, therefore, when the resource 1 includes a communication-aware resource, the communication channel with the same beamforming as the communication channel 1 of the communication-aware resource of the resource 1 can also be used for awareness, therefore, the above-mentioned communication channel that can be used for awareness is indicated by the channel indication information.

[0430] For analog beamforming, exemplarily, the first network device can employ spatial relation or quasi co-location (QCL) relation to determine the communication channels having the same analog beamforming as the communication channel 1. In implementation, when there is a certain communication channel having spatial relation or quasi co-location relation with the communication channel 1, it can be determined that the certain communication channel has the same analog beamforming (i.e. spatial filter) as the communication channel 1. Spatial relation means that one signal and another signal have the same spatial filter, and also means that the channel carrying one signal and the channel carrying another signal have the same spatial filter (i.e. analog beamforming). Quasi co-location relation means that two or more antenna ports (or signal sources) have certain common properties in terms of wireless channel characteristics, which are referred to as large-scale channel properties. If two antenna ports are similar or identical in terms of these large-scale channel properties, the two antenna ports are considered to have quasi co-location relation. The types of quasi co-location relation defined in 3GPP include: QCL-TypeA, QCL-TypeB, QCL-TypeC and QCL-TypeD, each type corresponds to a different combination of large-scale channel properties. In implementation, if the wireless channel properties of one antenna port can be deduced from the wireless channel properties of another antenna port, the two antenna ports have quasi co-location relation, and the wireless channels of the two antenna ports have quasi co-location relation, which can include at least one of the four types (such as QCL-TypeD, or a combination of QCL-TypeD and QCL-TypeA).

[0431] For digital beamforming, the first network device can explicitly indicate the precoding codebook employed by the first device. The first device can also determine the precoding codebook used by measuring the downlink reference signal. The first device can determine that different channels have the same digital beamforming according to the precoding codebook indicated by the first network device or according to the precoding codebook employed by itself.

[0432] When the first network device determines that each of the at least one communication channel has the same analog beamforming and digital beamforming as the communication channel 1, it can be considered that each of the at least one communication channel has the same beamforming as the communication channel 1, and further, the at least one communication channel is indicated by the channel indication information.

[0433] In the channel indication information, the at least one communication channel can be indicated in the following manner.

[0434] In an example, the at least one communication channel is indicated in the form of bitmap. One bit position corresponds to one channel, and the communication channel available for sensing is indicated by a specific value (1 or 0) specified in the bit position.

[0435] For example, the content of whether the communication channel in bitmap form is available for sensing 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), physical broadcast channel (PBCH) respectively, the value of the bit position is 1, indicating that the communication channel is available for sensing, therefore, the values of the 2nd bit position and the 3rd bit position are 1, indicating that the communication channels corresponding to the 2nd bit position and the 3rd bit position are available for sensing. Among them, the PDCCH corresponding to the 2nd bit position is the communication channel of the communication sensing resource in the resource 1 scheduled by the scheduling information, and the PDSCH corresponding to the 3rd bit position is the communication channel with the same beamforming as the PDCCH.

[0436] In another example, by the relationship information and the communication channel (communication channel 1) of the communication sensing resource of the resource 1 scheduled by the scheduling information, it is determined that the communication channel has the same analog beamforming as the communication channel 1. The relationship information is used to indicate the quasi co-site relationship 1 or the spatial relationship 1, and the relationship information can be carried in the scheduling information or other information (such as RRC signaling). For example, the relationship information is carried in the DCI (denoted as DCI2) carried on the communication channel 1, and DCI1 is used to schedule a new communication channel (denoted as communication channel 2). In the case that the communication channel 2 and the communication channel 1 satisfy the quasi co-site relationship 1 or the spatial relationship 1 indicated in the relationship information, it can be considered that the communication channel 2 and the communication channel 1 have the same analog beamforming.

[0437] For digital beamforming, the first device can determine whether the digital beamforming of the new communication channel and the communication channel 1 is the same based on the digital beamforming adopted by the communication channel 2 and the communication channel 1 respectively.

[0438] 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 thus 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 by the above-mentioned manner, and the at least one communication channel can be used for sensing.

[0439] 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 a quality threshold.

[0440] 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.

[0441] Here, the quality threshold can be determined based on the modulation and coding scheme (MCS) of the communication channel (communication channel 1) of the communication sensing resource 1. Taking the signal quality represented by SNR as an example, the communication channel 1 is PDSCH, and the minimum value of the SNR of the PDSCH corresponding to a specific MCS can be used as the quality threshold. In implementation, different MCSs correspond to different minimum values of SNR, and the offset value of SNR corresponding to different MCSs can be determined by looking up a table, so as to determine the minimum value of SNR corresponding to different MCSs. For example, the minimum value of SNR corresponding to MCS with index 1 is A, if the MCS of the PDSCH is index 4, then the minimum value of SNR corresponding to the MCS is A+△1, and if the index of the MCS of the PDSCH is 8, then the minimum value of SNR corresponding to the MCS is A+△2, where △1 and △2 are increments.

[0442] In another example, the scheduling information further includes beam information of a receiving communication beam that can be used for sensing, including beam ID, beam direction, beam width, and the like.

[0443] In implementation, the channel indication information, the relationship information, the judgment information and the beam information of the above four examples can be used in combination or independently. The perceivable receiving communication beam is determined by the beam information, at least one communication channel available for perception can be determined by the channel indication information or the relationship information, and a communication channel satisfying the quality threshold can be determined from the at least one communication channel based on the judgment information. If there are multiple communication channels satisfying the quality threshold, the best communication channel satisfying the quality threshold can be selected as the final perceivable communication channel, so as to determine the communication channel and the communication beam of the communication resource available for perception. In the embodiment in which the resource 1 includes the communication perception resource, the first device performs perception based on the communication signal transmitted on the communication perception resource, the type of the first device in different scenarios, and the device cooperating with the first device to perform perception are different.

[0444] For the scenarios of the first network device and the first device performing perception, such as the scenario 1 and the 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 the scenario 1, the first device is the first terminal device, and in the scenario 2, the first device is the second network device.

[0445] In the 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.

[0446] In the scenario 4 above, the first terminal device (an example of the first device) performs perception based on the communication signal transmitted on the communication perception resource.

[0447] In the embodiments provided by the method 100, the first device as the measurement node measures the link (i.e., the communication link, such as the link 1) on which the current transmission communication signal is transmitted based on the multiplexing measurement condition used to determine the communication link that can be used for sensing, so that the first network device can determine whether the link is used for sensing based on the measurement report obtained by measuring the link, and then the first network device can comprehensively consider the scheduling of the resources for communication and sensing according to whether the link is used for sensing, and indicate the scheduled resources (such as the resource 1) for the first device by sending the scheduling information to the first device, the scheduled resources including at least one of the sensing-only resource, the communication-only resource and the communication-sensing resource. In this way, in the case where the scheduled resources include the communication-sensing resource, since sensing can be performed based on the communication signal transmitted on the communication-sensing resource, no additional sensing resource is needed, the occupation of the sensing resource is reduced, and therefore the resource utilization rate can be effectively improved; in the case where the scheduled resources include the sensing-only resource or the communication-only resource, the normal communication and sensing can be maintained as much as possible, and the interference between the communication and the sensing is reduced. Therefore, the scheme of measuring the link (i.e., the communication link) on which the current transmission communication signal is transmitted based on the multiplexing measurement condition to determine whether the communication resource of the link is used for sensing in the embodiments of the present application can provide multiplexing basis for the scheduling of the resources for communication and sensing, and can improve the resource utilization rate as much as possible in the case where the normal communication and sensing can be maintained as much as possible, so as to maximize the utilization of the wireless resources, thereby improving the system performance.

[0448] The method 100 for integrating sensing and communication in the embodiments of the present application is described in detail from the step S110 to the step S150. It should be understood that the above process is only illustrative and should not be construed as limiting the embodiments of the present application.

[0449] In the above method, the first device does not send the measurement report when the link 1 does not satisfy the first type of condition. In other embodiments, the first device will send the measurement report regardless of the measurement of the link 1, and in the case 2 and the case 3 shown in FIG. 13, the link 1 is not used for sensing, therefore, in the case 2 and the case 3, the measurement report not only includes the multiplexing indication information used to indicate that the link 1 is not used for sensing, but in some embodiments, the measurement report also includes the measurement result, so that the first network device can distinguish whether the case 2 or the case 3 corresponds to that the link 1 is not used for sensing, to determine different scheduling strategies; in other embodiments, the measurement report can also include the indication information (denoted as indication information 1) used to indicate whether the link 1 satisfies the first type of condition, so that the first network device can distinguish whether the case 2 or the case 3 corresponds to that the link 1 is not used for sensing, to determine different scheduling strategies.

[0450] In the case that the measurement on link 1 is case 1 shown in FIG. 13, in step S1311, the first device sends a measurement report, the measurement report including multiplexing indication information, such as ACK information, for indicating that link 1 is available for sensing. In step S141, the first network device determines whether link 1 meets the sensing requirement according to the received measurement report. In the case that link 1 meets the sensing requirement based on the determination in step S141 (case 1.1), in step S1421, the first network device determines that the scheduling policy of the resources of link 1 is scheduling policy 1. In the case that link 1 does not meet the sensing requirement based on the determination in step S141 (case 1.2), in step S1422, the first network device determines that the scheduling policy of the resources of link 1 is scheduling policy 2.

[0451] In the case that the measurement on link 1 is case 2 shown in FIG. 13, in step S1312, the first device sends a measurement report, the measurement report including multiplexing indication information, such as NACK information, for indicating that link 1 is unavailable for sensing. In some embodiments, the measurement report further includes measurement results of link 1. In an example, the measurement results of link 1 include results corresponding to each condition obtained by measuring based on the first type of conditions and the second type of conditions, each condition corresponding result can include a measurement value, and each condition corresponding result can further include indication information for indicating whether link 1 meets the condition, for example. In another example, the measurement results include indication information for indicating at least one condition met by link 1, and can further 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 unavailable for sensing based on the multiplexing indication information, and further determine that link 1 meets the first type of conditions but does not meet the second type of conditions based on the measurement results, i.e., determine that the channel conditions of link 1 do not meet the conditions. Therefore, in step S1422, the first network device determines that the scheduling policy of the resources of link 1 is scheduling policy 2. In other embodiments, the measurement report further includes indication information 1 for indicating whether link 1 meets the first type of conditions, in this way, after receiving the measurement report, the first network device can determine that link 1 is unavailable for sensing based on the multiplexing indication information, and determine that link 1 only meets the first type of conditions based on the indication information 1, and therefore, in step S1422, the first network device determines that the scheduling policy of the resources of link 1 is scheduling policy 2.

[0452] In the case of Case 3 shown in FIG. 13, the first device also sends a measurement report, which includes multiplexing indication information indicating that link 1 is not available for sensing, such as NACK information. In some embodiments, the measurement report also includes measurement results of link 1. In an example, the measurement results of link 1 include results corresponding to each condition measured based on each condition of the first type, and each condition corresponding result can include a measurement value. In another example, the measurement results include indication information indicating at least one condition that link 1 satisfies, and can also include a measurement value corresponding to each condition in the at least one condition. In this way, after the first network device receives the measurement report, it can determine that link 1 is not available for sensing based on the multiplexing indication information, and further determine that link 1 does not satisfy the first type of condition based on the measurement results. Therefore, in step S1423, the first network device determines that the scheduling policy of the resources of link 1 is scheduling policy 3. In other embodiments, the measurement report also includes indication information 1 indicating whether link 1 satisfies the first type of condition. In this way, after the first network device receives the measurement report, it can determine that link 1 is not available for sensing based on the multiplexing indication information, and determine that link 1 does not satisfy the first type of condition based on the indication information 1. Therefore, in step S1423, the first network device determines that the scheduling policy of the resources of link 1 is scheduling policy 3.

[0453] FIG. 14 is another schematic flow chart of a process for measuring a communication link based on multiplexing measurement conditions to determine whether the communication link is available for sensing, according to an embodiment of the present application.

[0454] The process of FIG. 14 mainly involves the process of step S131 and step S140 of method 100. Comparing FIG. 14 with the process of FIG. 13, the main difference is that in FIG. 14, the multiplexing measurement conditions include not only the first type of condition and the second type of condition, but also the sensing requirement. Therefore, in the process of measuring link 1 by the first device in step 120, not only the process of measuring link 1 based on the first type of condition and the second type of condition, but also the process of measuring link 2 based on the sensing requirement to determine whether link 1 satisfies the sensing requirement, that is, determining whether link 1 satisfies the sensing requirement is performed by the first device. Based on this, the behavior of the first device for generating and sending the measurement report and the behavior of the first network device for determining the scheduling policy are also different. Hereinafter, the differences between FIG. 14 and FIG. 13 are mainly described, and the similarities between them are simply described.

[0455] The first device receives the measurement indication information, and the multiplexing measurement conditions indicated by the measurement indication information can include the first type of condition, the second type of condition and the sensing requirement, and link 1 is measured based on the first type of condition, the second type of condition and the sensing requirement.

[0456] In step S131a, the first device determines whether the link 1 satisfies the first type of condition.

[0457] In case that the link 1 does not satisfy the first type of condition (denoted as case A3), the first device does not send the measurement report.

[0458] In case A3, correspondingly, the first network device does not receive the measurement report, and without special circumstances, it can be determined that the link 1 is not available for sensing, and more specifically, it can be determined that the link 1 does not satisfy the first type of condition, i.e., the spatial domain resource of the link 1 is not available for sensing. Thus, in step S1433, the first network device determines the scheduling policy of the resource of the link 1 as the scheduling policy 3.

[0459] Here, the case A3 and the scheduling policy 3 corresponding to the case A3 are the same as the case 3 and the scheduling policy 3 corresponding to the case 3 described above, and will not be repeated here.

[0460] In case that the link 1 satisfies the first type of condition, the first device performs step S131b.

[0461] In step S131b, in case that the link 1 satisfies the first type of condition, the first device determines whether the link 1 satisfies the second type of condition.

[0462] In case that the link 1 does not satisfy the second type of condition (denoted as case A2), which means that the spatial domain resource of the link 1 is available for sensing, but the channel condition of the communication channel does not satisfy the condition, the first device determines that the link 1 is not available for sensing. Therefore, in step S1315, the first device sends the 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 the link 1 is not available for sensing, such as NACK information.

[0463] In case A2, based on the multiplexing indication information in the received measurement report, the first network device can determine that the link 1 is not available for sensing, and more specifically, it can be determined that the link 1 satisfies the first type of condition and does not satisfy the second type of condition, i.e., it is determined that the channel condition of the communication channel of the link 1 does not satisfy the condition. Thus, in step S1432, the first network device determines the scheduling policy of the resource of the link 1 as the scheduling policy 2.

[0464] Here, the case A2 and the scheduling policy 2 corresponding to the case A2 are the same as the case 2 and the scheduling policy 2 corresponding to the case 2 described above, and will not be repeated here.

[0465] In case that the link 1 satisfies the second type of condition, the first device performs step S131c.

[0466] In step S131c, the first device determines whether the link 1 meets the sensing requirement in the case that the link 1 meets the second type of condition.

[0467] Exemplarily, the first device determines whether the link 1 meets the sensing requirement according to the measured sensing auxiliary information. The specific description of the sensing auxiliary information and the sensing requirement can refer to the related description above, and will not be described here.

[0468] In the case that the link 1 meets the sensing requirement (denoted as case A1-1), in step S1314, the first device sends a measurement report, and the measurement report includes multiplexing indication information for indicating that the link 1 is perceivable, such as ACK information. Correspondingly, the first network device can know that the link 1 can be used for sensing based on the received measurement report, and thus in step S1431, the first network device determines that the scheduling strategy of the resource of the link 1 is scheduling strategy 1. The specific description of the scheduling strategy 1 can refer to the related description above, and will not be described here.

[0469] In the case that the link 1 does not meet the sensing requirement (denoted 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 for indicating that the link 1 is not perceivable, such as NACK information. Correspondingly, the first network device can know that the link 1 cannot be used for sensing based on the received measurement report, and thus in step S1432, the first network device determines that the scheduling strategy of the resource of the link 1 is scheduling strategy 2.

[0470] Combining FIG. 14 and FIG. 9, the step S131 of FIG. 9 includes the step S1315 or the step S1314 of FIG. 14, and the step S140 of FIG. 9 includes the step S1431, the step S1432 or the step S1433 of FIG. 14. The logical relationship between the respective steps is subject to the inherent logical relationship.

[0471] FIG. 15 is a schematic flowchart of a sensing-integrated method 200 provided by an embodiment of the present application.

[0472] The main difference between the above method 100 and the method 200 is that in the method 200, the first network device is the receiving end of the signal in the link measurement, and as a measurement node of the link measurement, the first device is the sending end of the signal in the link measurement. Hereinafter, the difference between the method 200 and the method 100 will be mainly described, and the similarities between the two will be simply described.

[0473] In the method 100, the first network device interacts with the first device, the first network device is the measurement node, the first network device measures the communication link (denoted as link 2) currently used for transmitting the communication signal to determine whether the link 2 is available for sensing, and the first network device comprehensively considers the allocation of the communication resource and the sensing resource based on the measurement of the link 2. In the method 200, compared with the method 100, the signaling overhead is reduced to some extent because the measurement node does not need to feed back the measurement report of the link measurement, and in the scenario of measuring the link between the network device and the terminal device, the power consumption of the terminal device can be effectively reduced because the terminal device does not need to perform the link measurement.

[0474] The method 200 of the embodiments of the present application can correspond to multiple scenarios, and the first device and the link 2 in different scenarios are different.

[0475] Scenario 5

[0476] The link 2 is a communication link between the first network device and the first terminal device, wherein the first device is the first terminal device.

[0477] Please refer to (b) of FIG. 1 and (b) of FIG. 4, the link 2 is a communication link A2, the communication link A2 is a link between a network device A (an example of the first network device) and a terminal device A (an example of the first terminal device), the terminal device A is the communication node for transmitting the communication signal, the network device A is the communication node for receiving the communication signal, the network device A is the measurement node for performing the link measurement, and the network device A comprehensively considers the allocation of the communication resource and the sensing resource based on the measurement of the communication link A2. In one example of (b) of FIG. 1, the scatterer on the communication link A2 is the sensing target. In one example of (b) of FIG. 4, the network device A or the terminal device A is the sensing target.

[0478] Scenario 6

[0479] The link 2 is a communication link between the first network device and the second network device, wherein the first device is the second network device.

[0480] Referring to (b) of FIG. 2 and (b) of FIG. 5, the link 2 is a communication link A2, the communication link A2 is a link between a network device A (an example of a first network device) and a network device B (an example of a second network device), the network device B is a communication node that transmits a communication signal, the network device A is a communication node that receives the communication signal, and the network device A is a measurement node of link measurement, and the network device A allocates the communication resource and the sensing resource based on a measurement result of the communication link A2. In one example of (b) of FIG. 2, a scatterer on the communication link A2 is a sensing target. In one example of (b) of FIG. 5, the network device A or the network device B is a sensing target.

[0481] In step S220, the first network device measures the link 2 (communication link).

[0482] In step S230, the first network device determines a scheduling policy of the resource of the link 2 (communication link).

[0483] In the above steps, the first network device measures the link 2 based on the multiplexing measurement condition, obtains a measurement result, and then determines the scheduling policy of the resource of the link 2 based on the measurement result.

[0484] In some embodiments, the measurement result includes a result corresponding to each condition obtained by measuring based on each condition, and each condition corresponding result can include a measurement value. For example, each condition corresponding result further includes indication information for indicating whether the link 2 meets the condition.

[0485] The first network device is configured with the multiplexing measurement condition, or other devices (such as core network elements) send information to the first network device for indicating the multiplexing measurement condition, so that the first network device obtains the multiplexing measurement condition.

[0486] In some embodiments, the multiplexing measurement condition includes a first type of condition, which is used to determine a communication link that can provide sensing information.

[0487] For example, the first type of condition includes at least one condition: a first condition, a second condition, a third condition, and a fourth condition.

[0488] In another embodiment, the multiplexing measurement condition not only includes the first type of condition, but also includes a second type of condition, and the second type of condition is related to the communication signal.

[0489] For example, the second type of condition includes at least one condition: a fifth condition, a sixth condition, a seventh condition, an eighth condition, and a ninth condition.

[0490] In some embodiments, the multiplexing measurement condition includes at least one of the first type of condition and the second type of condition.

[0491] The main indicators of the perception requirement include, but are not limited to, the unambiguous range, the resolution, the measurement accuracy, and the like.

[0492] For example, the perception requirement includes at least one of the following: the unambiguous range of the perception is within a preset range; the resolution of the perception is greater than or equal to a resolution threshold; the measurement accuracy of the perception is greater than or equal to a measurement accuracy threshold; and the channel variation rate meets a requirement.

[0493] For specific descriptions of the first type of condition, the second type of condition, and the perception requirement, reference can be made to the related descriptions above. For specific descriptions of the first network device measuring the link 2 based on the first type of condition, the second type of condition, and the perception requirement, reference can be made to the related descriptions above of the first device measuring the link 1 based on the first type of condition and the second type of condition, and the first network device measuring the link 2 based on the perception requirement, and the descriptions above of the link 1 are replaced by the link 2 here.

[0494] In some embodiments, in step S210 before step S220, the first device can send measurement assistance information to the first network device to assist the first network device in link measurement. The measurement assistance information includes at least one of the following information.

[0495] The position information of the first device, used to indicate the position of the first device.

[0496] The information of the transmitting communication beam on the link 2, which represents the communication beam of the first device for transmitting a communication signal on the link 2. For example, the information of the transmitting communication beam on the link 2 can include a beam identifier (such as a beam ID), a beam width, and a beam pointing direction.

[0497] The measurement assistance information described above can be used in combination with the first type of condition and the second type of condition of the multiplexing measurement condition. For example, the position information of the first device can be used in combination with the first type of condition and the second type of condition, and the information of the transmitting communication beam on the link 2 can be used in combination with the second type of condition. For specific descriptions, reference can be made to the related descriptions above of the process of measuring the link based on the first type of condition and the second type of condition, and the descriptions above are not repeated here.

[0498] Next, taking the multiplexing measurement condition including the first type of condition, the second type of condition, and the perception requirement as an example, the steps S220 and S230 are described in combination with the first network device measuring the link 2 based on the multiplexing measurement condition.

[0499] FIG. 16 is another schematic flowchart of a process for link measurement based on multiplexing measurement conditions to determine whether a communication link is available for sensing, according to an embodiment of the present application.

[0500] In the embodiment in which the multiplexing measurement conditions include the first type of condition, the second type of condition, and the sensing requirement, there are four cases (case B1-1, case B1-2, case B2, and case B4 below) of the results of the measurement of link 2 by the first network device based on the above multiplexing measurement conditions, and the first network device determines different scheduling strategies based on different cases.

[0501] Case B1-1 and the scheduling strategy of case B1-1

[0502] In case B1-1, based on the measurement result of link 2 (the communication link), it is determined that link 2 satisfies the first type of condition, the second type of condition, and the sensing requirement, so the first network device determines that link 2 is available for sensing, and therefore determines that the scheduling strategy of link 2 is scheduling strategy 2.

[0503] Referring to FIG. 16, for example, in step S230a, based on the measurement result, the first network device determines whether link 2 satisfies the first type of condition, in the case where 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, in the case where link 2 satisfies the second type of condition, in step S230c, the first network device determines whether link 2 satisfies the sensing requirement, in the case where link 2 satisfies the sensing requirement, the first network device determines that link 2 satisfies the first type of condition, the second type of condition, and the sensing requirement, which means that link 2 is available for sensing, and therefore, in step S2311, the first network device determines that the scheduling strategy of the resources of link 2 is scheduling strategy 1.

[0504] It should be noted that case B1-1 of method 200 is the same as case 1.1 of method 100 described above, and the measured communication link satisfies the first type of condition, the second type of condition, and the sensing requirement. Correspondingly, the scheduling strategy 1 corresponding to case B1-1 is the same as the scheduling strategy 1 corresponding to case 1.1 described above. For specific description of case B1-1 and the scheduling strategy 1 corresponding to case B1-1, reference can be made to the related description above, which will not be described here again.

[0505] Case B1-2 and the scheduling strategy of case B1-2

[0506] In case B1-2, based on the measurement result of link 2 (the communication link), it is determined that link 2 satisfies the first type of condition and the second type of condition, but does not satisfy the sensing requirement, which means that the sensing result obtained by sensing the sensing target using the communication resources of link 2 does not meet the requirement, therefore, the first network device determines that link 2 is not available for sensing, and determines that the scheduling strategy of link 2 is scheduling strategy 2.

[0507] Referring to FIG. 16, exemplarily, in step S230a, based on the measurement result, the first network device determines whether the link 2 satisfies the first type of condition, in the case where the link 2 satisfies the first type of condition, in step S230b, the first network device determines whether the link 2 satisfies the second type of condition, in the case where the link 2 satisfies the second type of condition, in step S230c, the first network device determines whether the link 2 satisfies the sensing requirement, in the case where the link 2 does not satisfy the sensing requirement, the first network device determines that the link 2 satisfies the first type of condition and the second type of condition, but does not satisfy the sensing requirement, therefore, in step S2312, the first network device determines that the scheduling policy of the resource of the link 2 is the scheduling policy 2.

[0508] It should be noted that the case B1-2 of the method 200 is the same as the case 1.2 of the method 100 described above, the measured communication link satisfies the first type of condition and the second type of condition but does not satisfy the sensing requirement, correspondingly, the scheduling policy 2 corresponding to the case B1-2 is the same as the scheduling policy 2 corresponding to the case 1.2 described above, and the specific description of the case B1-2 and the scheduling policy 2 corresponding to the case B1-2 can refer to the related description above, which will not be described here again.

[0509] Case B2 and the scheduling policy of the case B2

[0510] In the case B2, based on the measurement result of the link 2 (communication link), it is determined that the link 2 satisfies the first type of condition and does not satisfy the second type of condition, which means that the spatial domain resource of the link 2 can be used for sensing, but the channel condition of the communication channel does not satisfy the condition, therefore, the first network device determines that the link 2 cannot be used for sensing, and determines that the scheduling policy of the resource of the link 2 is the scheduling policy 2.

[0511] Referring to FIG. 16, exemplarily, in step S230a, based on the measurement result, the first network device determines whether the link 2 satisfies the first type of condition, in the case where the link 2 satisfies the first type of condition, in step S230b, the first network device determines whether the link 2 satisfies the second type of condition, in the case where the link 2 does not satisfy the second type of condition, the first network device determines that the 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 policy of the resource of the link 2 is the scheduling policy 2.

[0512] It should be noted that the case B2 of the method 200 is the same as the case 2 of the method 100 described above, the measured communication link satisfies the first type of condition but does not satisfy the second type of condition, correspondingly, the scheduling policy 2 corresponding to the case B2 is the same as the scheduling policy 2 corresponding to the case 2 described above, and the specific description of the case B2 and the scheduling policy 2 corresponding to the case B2 can refer to the related description above, which will not be described here again.

[0513] Case B3 and the scheduling policy of case B3

[0514] In case B3, based on the measurement result of link 2 (communication link), it is determined that link 2 does not satisfy the first type of condition, meaning that the spatial domain resource of link 2 is not available for sensing, therefore, the first network device determines that link 2 is not available for sensing, and determines that the scheduling policy of the resource of link 2 is scheduling policy 3.

[0515] Referring 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, in the case that link 2 does not satisfy the first type of condition, the first network device determines that link 2 is not available for sensing, therefore, in step S2313, the first network device determines that the scheduling policy of the resource of link 2 is scheduling policy 3.

[0516] It should be noted that case B3 of method 200 is the same as case 3 of method 100 described above, the measured communication link does not satisfy the first type of condition, correspondingly, the scheduling policy 3 corresponding to case B3 is the same as the scheduling policy 3 corresponding to case 3 described above, and the specific description of case B3 and the scheduling policy 3 corresponding to case B3 can refer to the related description above, which will not be repeated here.

[0517] In step S240, the first network device sends the scheduling information.

[0518] In this step, the first network device determines and sends the scheduling information based on the determined scheduling policy of the communication resource of link 2. Wherein, the scheduling information indicates the scheduled resource (denoted as resource 2), and the resource 2 includes at least one of the following resources: only sensing resource, only communication resource, communication and sensing resource.

[0519] Here, the specific description of resource 2 and the scheduling information can refer to the related description of resource 1 and the scheduling information of method 100, which will not be repeated here.

[0520] In the embodiment in which the above-mentioned resource 2 includes the communication and sensing resource, in step S250, the first network device and the first device perform sensing based on the communication signal transmitted on the communication and sensing resource.

[0521] In the embodiment provided by the method 200, the first network device as the measurement node measures the link (i.e., the communication link, such as the link 2) currently transmitting the communication signal based on the multiplexing measurement condition for determining the communication link available for sensing, which can enable the first network device to determine whether the link is used for sensing based on the measurement result of the link, and further, the first network device can comprehensively consider the scheduling of the resources for communication and sensing based on whether the link is used for sensing, and indicate the scheduled resources (such as the resource 2) for the first device by sending the scheduling information to the first device, where the scheduled resources include at least one of the sensing-only resource, the communication-only resource, and the communication-sensing resource. In this way, in the case where the scheduled resources include the communication-sensing resource, since sensing can be performed based on the communication signal transmitted on the communication-sensing resource, no additional sensing resource is needed, the occupation of the sensing resource is reduced, and therefore, the resource utilization rate can be effectively improved; in the case where the scheduled resources include the sensing-only resource or the communication-only resource, the normal communication and sensing can be maintained as much as possible, and the interference between the communication and sensing is reduced. Therefore, the scheme of measuring the link (i.e., the communication link) currently transmitting the communication signal based on the multiplexing measurement condition to determine whether the communication resource of the link is used for sensing in the embodiment of the present application can provide multiplexing basis for the scheduling of the resources for communication and sensing, and in the case where the normal communication and sensing can be maintained as much as possible, the resource utilization rate is improved as much as possible, so as to maximize the utilization of the wireless resources, thereby improving the system performance.

[0522] In addition, since the measurement node does not need to feed back the measurement result of the link measurement, the signaling overhead is reduced to a certain extent, and in the scenario of measuring the link between the network device and the terminal device, since the terminal device does not need to perform the link measurement, the power consumption of the terminal device can be effectively reduced.

[0523] FIG. 17 is a schematic flowchart of a method 300 for communication-sensing integration provided by an embodiment of the present application.

[0524] In the method 300, the method 300 is described from the perspective of the interaction between the first network device and the first device, taking the first network device and the first device as an example. The first network device interacts with the first device, the first device as the measurement node measures the communication link (hereinafter referred to as the first link) currently transmitting the communication signal based on the multiplexing measurement condition to determine whether the first link is available for sensing, and the first network device comprehensively considers the scheduling of the communication resource and the sensing resource based on the measurement of the first link.

[0525] The method 300 can be similar to the method 100. Specifically, the first network device of the method 300 is similar to the first network device of the method 100, the first device of the method 300 is similar to the first device of the method 100, and the first link of the method 300 is similar to the link 1 of the method 100; the scenarios applicable to the method 300 are the same as the scenarios (scenario 1 to scenario 4 described above) applicable to the method 100, and correspondingly, the explanations of the first device and the first link in different scenarios are also the same as the first device and the link 1 of the method 100, and therefore, the specific descriptions here can refer to the related descriptions above, and will not be repeated.

[0526] In step S301, the first device measures the first link based on the multiplexing measurement condition.

[0527] In some embodiments, the first network device sends, to the first device, measurement indication information including condition information for indicating the multiplexing measurement condition. Correspondingly, the first device receives the measurement indication information.

[0528] In other embodiments, another device (such as a core network element) sends, to the first device, the measurement indication information, and correspondingly, the first device receives the measurement indication information.

[0529] In some embodiments, in a case where 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 including at least one of:

[0530] position information of the first network device;

[0531] information of a second communication beam, the second communication beam being a transmission communication beam on the first link;

[0532] information of a sensing target;

[0533] information of a sensing area;

[0534] information of a first sensing beam, the first sensing beam being a sensing beam through which the first network device transmits a sensing signal.

[0535] 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.

[0536] Regarding the multiplexing measurement condition, in some embodiments, the multiplexing measurement condition includes a first type of condition. In this way, the first device measures the first link based on the first type of condition. The specific description can refer to the related description of the method 100.

[0537] In some embodiments, the multiplexing measurement condition comprises 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 more details, please refer to the method 100 and the related description of FIG. 13.

[0538] In some embodiments, the multiplexing measurement condition comprises a first type of condition, a second type of condition and a sensing requirement. Thus, the first device measures the first link based on the first type of condition, the second type of condition and the sensing requirement. For more details, please refer to the method 100 and the related description of FIG. 14.

[0539] For more details about the first type of condition, the second type of condition and the sensing requirement, please refer to the related description of the method 100 above, which will not be repeated here.

[0540] In step S310, the first device sends a measurement report to the first network device, the measurement report being obtained by the first device measuring the first link based on the multiplexing measurement condition.

[0541] In some embodiments, the measurement report comprises multiplexing indication information, the multiplexing indication information being used to indicate whether the first link can be used for sensing.

[0542] In step S320, the first network device determines the first scheduling information according to the measurement report.

[0543] In some embodiments, the first scheduling information is used to indicate the first resource, the first resource comprising at least one of the following resources: only sensing resource, only communication resource, communication and sensing resource.

[0544] In this step, in some embodiments, the first network device determines a scheduling strategy of the resource of the first link based on the received measurement report, and determines the first scheduling information based on the scheduling strategy of the resource of the first link.

[0545] In some embodiments, the first device selectively sends the measurement report based on the situation of measuring the first link, and the specific content of the sent measurement report is different, and accordingly, the behavior of the first network device determining the first scheduling information according to the measurement report is also different. For more details, please refer to the embodiments shown in FIG. 13 and FIG. 14 above.

[0546] In the embodiment where the multiplexing measurement condition includes the first type of condition and the second type of condition, with reference to FIG. 13, in the case where the first link satisfies the first type of condition and the second type of condition (i.e., case 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 sensing; in the case where the first link satisfies the first type of condition but does not satisfy the second type of condition (i.e., case 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 sensing; in the case where the first link does not satisfy the first type of condition (i.e., case 3), the first device does not send (or is prohibited from sending) a measurement report.

[0547] For specific descriptions herein, reference can be made to the related descriptions of the measurement report in case 1, case 2, and case 3 in FIG. 13 of method 100, which will not be repeated herein.

[0548] In case 1 described above, the measurement report sent by the first device not only includes multiplexing indication information used to indicate that the first link can be sensed, but in some embodiments, the measurement report also includes sensing assistance information, so as to facilitate the first network device to further determine whether the first link can be used for sensing. For specific descriptions of the sensing assistance information, reference can be made to the related descriptions above, which will not be repeated herein.

[0549] In case 1 described above and in the embodiment where the measurement report includes sensing assistance information, the first network device determines that the first link satisfies the first type of condition and the second type of condition based on the multiplexing indication information, and thus determines a scheduling strategy of the resources of the first link according to the sensing assistance information and the sensing requirement. For specific descriptions of the sensing requirement, reference can be made to the related descriptions above, which will not be repeated herein.

[0550] In an example, in the case where it is determined according to the sensing assistance information that the first link satisfies the sensing 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 sensing.

[0551] In another example, in the case where it is determined according to the sensing assistance information that the first link does not satisfy the sensing requirement, the scheduling strategy of 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 sensing resources are orthogonal to the communication resources of the first link in the time domain and / or the frequency domain.

[0552] In case 2 described above, the first network device determines that the first link cannot be used for sensing based on the multiplexing indication information, and more specifically, it can be determined that the first link satisfies the first type of condition but does not satisfy the second type of condition, and thus the first network device determines the scheduling strategy of the resources of the first link to be the second scheduling strategy.

[0553] Here, the first scheduling policy and the second scheduling policy can be analogous to the scheduling policy 1 and the scheduling policy 2 of the method 100 respectively, and specific descriptions about the first scheduling policy and the second scheduling policy can be referred to the related descriptions about the scheduling policy 1 and the scheduling policy 2 respectively in the foregoing, and will not be repeated here.

[0554] In the embodiment in which the multiplexing measurement condition includes the first type of condition, the second type of condition and the sensing requirement, with reference to FIG. 14, in the case where the first link satisfies the first type of condition, the second type of condition and the sensing requirement (i.e., case 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 sensing; in the case where the first link satisfies the first type of condition and the second type of condition, and does not satisfy the sensing requirement (i.e., case 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 sensing; in the case where it is determined that the first link satisfies the first type of condition and does not satisfy the second type of condition (i.e., case 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 sensing; in the case where the first link does not satisfy the first type of condition (i.e., case A3), the first device does not send (or is prohibited from sending) a measurement report.

[0555] Specific descriptions about this can be referred to the related descriptions about the measurement report in the case A1-1, the case A1-2, the case A2 and the case A3 in FIG. 14, and will not be repeated here.

[0556] In the case A1-1 described above, the first network device determines based on the multiplexing indication information that the first link can be used for sensing, specifically, it can be determined that the first link satisfies the first type of condition, the second type of condition and the sensing requirement, therefore, the first network device determines that the scheduling policy of the resources of the first link is the first scheduling policy.

[0557] In the case A1-2 described above, the first network device determines based on the multiplexing indication information that the first link cannot be used for sensing, therefore, the first network device determines that the scheduling policy of the resources of the first link is the second scheduling policy.

[0558] In the case A2 described above, the first network device determines based on the multiplexing indication information that the first link cannot be used for sensing, therefore, the first network device determines that the scheduling policy of the resources of the first link is the second scheduling policy.

[0559] Here, the first scheduling policy and the second scheduling policy can be analogous to the scheduling policy 1 and the scheduling policy 2 of the method 100 respectively, and specific descriptions about the first scheduling policy and the second scheduling policy can be referred to the related descriptions about the scheduling policy 1 and the scheduling policy 2 respectively in the foregoing, and will not be repeated here.

[0560] Based on the above manner, the first network device determines the scheduling policy of the resources of the first link, and determines the scheduling information based on the scheduling policy of the first link.

[0561] As described above, the first network device is the device that decides the resource scheduling. In the process of resource scheduling, the first network device not only performs resource scheduling on the first device based on the determined scheduling policy of the resources of the first link, but also performs resource scheduling in combination with the resources of all devices connected to the first network device and different services. Therefore, the first resource finally scheduled for the first device may be different from the scheduling policy determined based on the link measurement, and the two are not absolutely related.

[0562] In the case where the first device sends the measurement report including the multiplexing indication information (such as case 1 and case 2), the scheduling policy of the resources of the first link determined by the first network device is the first scheduling policy or the second scheduling policy, and the scheduling information determined based on the first scheduling policy or the second scheduling policy can be the first scheduling information.

[0563] It should be understood that the specific content of the first scheduling information determined based on the first scheduling policy and the first scheduling information determined based on the second scheduling policy can be the same or different, and is subject to the overall resource management situation of the first network device.

[0564] For example, the first resource indicated by the first scheduling information determined based on the first scheduling policy includes the communication-aware resource, and the first resource indicated by the first scheduling information determined based on the second scheduling policy includes the only-aware resource and the communication-aware resource. For another example, the first resource indicated by the first scheduling information determined based on the first scheduling policy includes the communication-aware resource, and the first resource indicated by the first scheduling information determined based on the second scheduling policy includes the only-aware 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.

[0565] Regarding the first scheduling information, in some embodiments, the first scheduling information includes destination information, and the destination information is used to determine that the first resource is only used for communication, or the first resource is only used for awareness, or at least part of the first resource is used for awareness and communication; or,

[0566] The downlink control information DCI carrying the first scheduling information is scrambled by a radio network temporary identifier RNTI, and the RNTI is used to indicate that the first resource is only used for communication, or the first resource is only used for awareness, or at least part of the first resource is used for awareness and communication.

[0567] In some embodiments, the first scheduling information further comprises priority information; and in a case that at least part of the first resources overlap with other resources in time domain and frequency domain, the priority information is used to indicate that the at least part of the resources are used to preferentially carry a communication signal or preferentially carry a sensing signal, wherein the first resources are sensing resources, and the other resources are communication resources, or the first resources are communication resources, and the other resources are sensing resources.

[0568] The first scheduling information herein can be analogous to the scheduling information of method 100, and the first resources can be analogous to the resources 1 of method 100. For specific descriptions of the first scheduling information and the first resources, reference can be made to the related descriptions of the scheduling information and the resources 1 above, which will not be described herein again.

[0569] In step S330, the first network device sends the first scheduling information.

[0570] Correspondingly, the first device receives the first scheduling information and determines the first resources based on the first scheduling information.

[0571] In embodiments in which the first resources comprise communication-sensing resources, the first device performs sensing based on the communication signals transmitted on the communication-sensing resources. The types of the first device in different scenarios and the devices that perform sensing in cooperation with the first device are different.

[0572] For the scenarios in which the first network device and the first device perform sensing, such as scenario 1 and scenario 2 above, the first network device and the first device perform sensing based on the communication signals transmitted on the communication-sensing resources. In scenario 1, the first device is a first terminal device, and in scenario 2, the first device is a second network device. In scenario 3 above, a first terminal device (an example of the first device) and a second terminal device perform sensing based on the communication signals transmitted on the communication-sensing resources. In scenario 4 above, a first terminal device (an example of the first device) performs sensing based on the communication signals transmitted on the communication-sensing resources in a self-sensing and self-receiving manner.

[0573] In case 3 or case A3 in which the first device does not send the measurement report described above, in a case in which the first network device does not receive the measurement report obtained by the first device based on the multiplexing measurement condition for measuring the first link, the first network device determines that the scheduling strategy of the resources of the first link is a third scheduling strategy, and the third scheduling strategy is used to indicate that the sensing resources and the communication resources of the first link do not affect each other in time domain and / or frequency domain. In addition, the first network device determines second scheduling information based on the third scheduling strategy and sends the second scheduling information, wherein the second scheduling information is used to indicate second resources, and the second resources comprise at least one of the following resources: only sensing resources, only communication resources, and communication-sensing resources.

[0574] 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 can be the same or different, and is subject to the overall resource management situation of the first network device.

[0575] Here, the third scheduling strategy, the second scheduling information, and the second resource can be respectively analogous to the scheduling strategy 3, the scheduling information, and the resource 1 of the method 100. The specific description of the third scheduling strategy, the second scheduling information, and the second resource can be referred to the related description above, and will not be described herein again.

[0576] FIG. 18 is a schematic flowchart of the method 400 of the integrated sensing and communication provided by the embodiments of the present application.

[0577] In the method 400, the method 400 is described from the perspective of the interaction between the first network device and the first device, taking the first network device and the first device as an example. The first network device interacts with the first device. As a measurement node, the first network device measures the communication link (hereinafter referred to as the first link) currently used for transmitting a communication signal based on the multiplexing measurement condition, to determine whether the first link can be used for sensing. The first network device considers the scheduling of the communication resource and the sensing resource based on the measurement of the first link.

[0578] The method 400 can be analogous to the method 200. Specifically, the first network device of the method 400 is analogous to the first network device of the method 200, the first device of the method 400 is analogous to the first device of the method 200, and the first link of the method 400 is analogous to the link 2 of the method 100. The scenarios applicable to the method 400 are the same as the scenarios applicable to the method 200 (the scenarios 5 and 6 described above). Correspondingly, the explanations of the first device and the first link in different scenarios are the same as the explanations of the first device and the link 2 of the method 200. Therefore, the specific description here can be referred to the related description above, and will not be described herein again.

[0579] 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.

[0580] In some embodiments, the multiplexing measurement condition is configured in the first network device.

[0581] In other embodiments, other devices (such as core network elements) send information indicating the information multiplexing measurement condition to the first network device. In this way, the first network device obtains the multiplexing measurement condition.

[0582] The specific description of the multiplexing measurement condition can be referred to the related description of the multiplexing measurement condition in the method 200, and will not be described herein again.

[0583] Before step S410, the first device can send measurement assistance information to the first network device to assist the first network device to perform link measurement. The specific description of the measurement assistance information can refer to the related description of the measurement assistance information in the method 200, and will not be repeated here.

[0584] In step S420, the first network device determines the scheduling information according to the measurement result.

[0585] In this step, in some embodiments, the first network device determines a scheduling policy of the resources of the first link according to the measurement result, and determines the scheduling information based on the scheduling policy of the resources of the first link. It is illustrated in combination with the above Fig. 16.

[0586] In an example, in the case that the first link satisfies the first type of condition, the second type of condition and the sensing requirement according to the measurement result (i.e. case B1-1), the first network device determines that the scheduling policy of the resources of the first link is a first scheduling policy, and the first scheduling policy is used to indicate that the communication resources of the first link can be used for sensing.

[0587] In another example, in the case that the first link satisfies the first type of condition and the second type of condition and does not satisfy the sensing requirement according to the measurement result (i.e. case B1-2), the first network device determines that the scheduling policy of the resources of the first link is a second scheduling policy, and the second scheduling policy is used to indicate that the sensing resources are orthogonal to the communication resources of the first link in the time domain and / or the frequency domain.

[0588] In another example, in the case that the first link satisfies the first type of condition and does not satisfy the second type of condition according to the measurement result (i.e. case B2), the first network device determines that the scheduling policy of the resources of the first link is the second scheduling policy.

[0589] In another example, in the case that the first link does not satisfy the first type of condition according to the measurement result (i.e. case B3), the first network device determines that the scheduling policy of the resources of the first link is a third scheduling policy, and the third scheduling policy is used to indicate that the sensing resources and the communication resources of the first link do not affect each other in the time domain and the frequency domain.

[0590] Here, the first scheduling policy, the second scheduling policy and the third scheduling policy can be respectively analogous to the scheduling policy 1, the scheduling policy 2 and the scheduling policy 3 of the method 200, and the specific description of the first scheduling policy, the second scheduling policy and the third scheduling policy can be respectively referred to the related description of the scheduling policy 1, the scheduling policy 2 and the scheduling policy 3 above, and will not be repeated here.

[0591] Based on the above manner, the first network device determines the scheduling policy of the resources of the first link, determines the scheduling information based on the scheduling policy of the first link, and the scheduling information is used to indicate the first resources, and the first resources include at least one of the following resources: only sensing resources, only communication resources, and communication-sensing resources.

[0592] The scheduling information herein can be analogous to the scheduling information of the method 200, the first resources can be analogous to the resources 2 of the method 200, and the specific description of the scheduling information and the first resources can refer to the related description of the scheduling information and the resources 2 above, and will not be described here.

[0593] The method of integrated sensing and communication according to the embodiments of the application is described in detail above, and the device of integrated sensing and communication according to the embodiments of the application will be described in detail below with reference to FIGS. 19-20.

[0594] FIG. 19 shows a device 500 of integrated sensing and communication according to an embodiment of the application. The device 500 can be a first network device or a first device, or the device 500 can be a chip or a processor in the first network device, or the device 500 can be a chip or a processor in the first device. The device 500 includes a transceiver unit 510 and a processing unit 520.

[0600] In a case where the first link satisfies the first type of condition and does not satisfy the second type of condition, the measurement report is sent to the first network device, and the multiplexing indication information is used to indicate that the first link is unavailable for sensing.

[0601] The transceiver 510 is further configured to receive measurement indication information sent by the first network device, the measurement indication information including condition information used to indicate the multiplexing measurement condition.

[0602] The first resource includes the communication-sensing resource, and the transceiver 510 is further configured to perform sensing based on a communication signal transmitted on the communication-sensing resource.

[0605] The transceiver 510 is further configured to send the first scheduling information to the first device.

[0606] In some embodiments, the transceiver 510 is specifically configured to, in a case where the multiplexing indication information is used to indicate that the first link is available for sensing, determine a scheduling strategy of a resource of the first link according to the sensing assistance information and the sensing requirement, and determine the first scheduling information according to the scheduling strategy of the resource of the first link.
