[0001] The present application claims priority to the Chinese patent application No. 202410818244.4, filed on June 21, 2024, and entitled "A communication sensing method and device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] Embodiments of the present application relate to the field of communication sensing, and in particular to a communication sensing method and device. BACKGROUND

[0003] Future mobile communication systems are expected to have both communication and sensing capabilities. With the continuous increase of frequency points, wider frequency bands, and the use of ultra-massive multiple output (UM-MIMO) technology, communication signals have high resolution in the time delay domain, Doppler domain, and angle domain, which makes it possible to use communication signals for high-precision sensing. In addition, new services such as digital twin and Internet of Vehicles drive the convergence of communication systems and radar systems in terms of spectrum, technology trends, and applications. Therefore, it is necessary to design wireless communication and sensing integrally, and ultimately achieve communication and sensing capability assistance, network reciprocity, improved frequency efficiency, and reduced hardware cost.

[0004] Integrated sensing and communication (ISAC) is a key technology in the next generation of wireless communication networks, which aims to integrate wireless communication and sensing functions in the same system, and use various propagation characteristics of wireless signals to achieve positioning, detection, imaging, and identification of targets, etc., to obtain information about the surrounding physical environment, exploit communication capabilities, and enhance user experience. Therefore, how to achieve integrated sensing and communication is a technical problem that needs to be solved at present. SUMMARY

[0005] Embodiments of the present application provide a communication sensing method and device, which can reduce sensing identification probability, reduce resource waste, and improve sensing accuracy and communication efficiency.

[0008] According to the first aspect, by receiving the first information used to assist sensing, the sensing accuracy and communication efficiency can be improved. In addition, when the first information is also used to configure the triggering condition, the measurement report can be reported only when the corresponding measurement report of the first node satisfies the triggering condition, which can avoid the problem of sensing failure and resource waste caused by reporting the measurement report without reference to any factor.

The embodiments of the present application described below do not constitute a limitation on the protection scope of the present application.

[0070] For the convenience of understanding, the technical terms related to the embodiments of the present application are introduced first.

[0071] I. ISAC

[0072] ISAC can also be referred to as joint communications and sensing (JCS), or joint communications and sensing (JCAS).

[0073] In a mobile communication system, higher frequency bands (millimeter waves or even terahertz), wider bandwidths, and larger-scale antenna arrays make high-precision and high-resolution sensing possible, so that ISAC can be implemented in one system, making the functions of communication and sensing complementary. On the one hand, the entire communication network can serve as a huge sensor, and network elements send and receive wireless signals, and use the transmission, reflection, and scattering of radio waves to better perceive and understand the physical world. By obtaining distance, speed, angle information, and the attributes of the target from the wireless signals, high-precision positioning, gesture capture, motion recognition, detection of passive objects, imaging, and environmental reconstruction, and other new services can be provided, and the concept of "network as a sensor" can be realized. On the other hand, the high-precision positioning, imaging, and environmental reconstruction capabilities provided by sensing can help improve communication performance, such as more accurate beamforming and faster beam failure recovery, and the concept of "sensing-aided communication" can be realized. Sensing is also a new channel that connects the physical world and the biological world to the digital world by observing and sampling them. The application scenarios of future ISAC systems are likely to include ultra-high-precision positioning, synchronous imaging, map construction, and human sensory enhancement.

[0074] II. Sensing

[0075] The sensing process is implemented by using sensing signals, which can be signals used for sensing a target or detecting a target, or signals used for sensing environmental information or detecting environmental information. For example, the sensing signals can be electromagnetic waves sent by a network device for sensing environmental information.

[0076] The sensing signals can generate echo signals after being affected by the sensing target in the environment. The time delay of the echo signals relative to the transmitted sensing signals reflects the distance of the sensing target, and the Doppler frequency shift of the echo signals relative to the transmitted sensing signals reflects the relative speed of the sensing node and the sensing target. Then, the distance and / or moving speed of the sensing target can be determined by performing sensing measurement on the echo signals corresponding to the sensing signals. Further, the actual position of the sensing target can be determined based on the distance and / or moving speed of the sensing target.

[0077] In the embodiments of the present application, the echo signal of the sensing signal after the sensing target acts on it can also be referred to as a signal reflected by the sensing target, a signal refracted by the sensing target, a signal diffracted by the sensing target, a signal transmitted by the sensing target, a signal scattered or diffracted by the sensing target, and the like, which are not limited herein.

[0078] In the embodiments of the present application, the sensing target can include various tangible objects on the ground that can be sensed, such as mountains, forests, or buildings, and can also include movable objects such as vehicles and terminals. The sensing target is a target that can be sensed by a network device with sensing function, and the target can feed back electromagnetic waves to the network device. The sensing target can also be referred to as a detected target, a sensed object, a detected object, or a sensed device, which are not limited herein.

[0079] It can be understood that the above-mentioned sensing target can be moving or fixed, and can be active or passive. Active can mean that the sensing target has data processing capability, such as a base station, a mobile phone, a router, a vehicle, a drone, a radio frequency identification (RFID) device, and the like. Passive can mean that the sensing target does not have data processing capability, such as animals, plants, vehicles, buildings, and the like.

[0080] III. Sensing mode

[0081] In the current 3rd generation partnership project (3GPP) discussion, it has been determined that the sensing mode can be divided into the following 6 modes:

[0082] (1) Base station self-transmission and self-reception: the sensing signal is transmitted by the base station, and the echo signal is received by the base station after being reflected by the target in the environment.

[0083] (2) Base station A transmission and base station B reception: the sensing signal is transmitted by base station A, and the echo signal is received by base station B after being reflected by the target in the environment.

[0084] (3) Base station transmission and terminal reception: the sensing signal is transmitted by the base station, and the echo signal is received by the terminal after being reflected by the target in the environment.

[0085] (4) Terminal transmission and base station reception: the sensing signal is transmitted by the terminal, and the echo signal is received by the base station after being reflected by the target in the environment.

[0086] (5) Terminal self-transmission and self-reception: the sensing signal is transmitted by the terminal, and the echo signal is received by the terminal after being reflected by the target in the environment.

[0087] (6) Terminal A sends and terminal B receives: the sensing signal is sent by terminal A, and the echo signal is received by terminal B after being reflected by the target in the environment.

[0088] Among them, the sensing modes (1) and (5) can be called self-sending and self-receiving modes, and the sensing modes (2)-(4) and (6) can be called A-sending and B-receiving modes, which are not limited. The sensing method provided in the present application can be applied to any one or more of the above sensing modes, which is not limited.

[0089] Four, joint sensing

[0090] Joint sensing can also be called cooperative sensing. For example, in the ISAC scenario, multiple sensing nodes can jointly provide sensing services to provide high-quality sensing services, that is, two or more nodes can jointly sense the target.

[0091] At present, when multiple sensing nodes jointly sense, it depends on the relative position of the sensing node and the sensing target. However, in this case, it cannot be determined that there is a line-of-sight path (LOS path) between the sensing node and the sensing target, that is, it cannot be determined that there is no other passive object between the sensing node and the sensing target. The relative position of the sensing node and the sensing target indicated by the measurement report may be inaccurate. At this time, if the measurement report is directly reported and the sensing node providing the sensing service is switched based on the measurement report, it will cause sensing failure and resource waste. Further, in the current communication measurement, such as radio resource management (RRM) measurement, L1 beam measurement and sensing measurement in the new radio (NR) system, they are independent, which leads to low sensing accuracy and low communication efficiency. In this case, how to integrate communication and sensing to improve sensing accuracy and communication efficiency has become a mainstream trend.

[0092] Based on this, the embodiment of the present application provides a sensing method, which receives first information of auxiliary sensing to assist the first node in sensing measurement, thereby improving the sensing accuracy and the communication efficiency. In addition, the first information is also used to configure a trigger condition, and the measurement report feedback can be performed according to the trigger condition, which can reduce the sensing failure probability and reduce resource waste.

[0093] The technical solutions of the embodiments of the present application can be used for supporting sensing various communication systems, which can be a third generation partnership project (3GPP) communication system, for example, a long term evolution (LTE) system, a NR system, a 5th generation (5G) system, a vehicle to everything (V2X) system, or a system of mixed networking of LTE and 5G, or a device-to-device (D2D) communication system, a machine to machine (M2M) communication system, an internet of things (IoT), and a next generation communication system. The communication system can also be a non-3GPP communication system, which is not limited. In the present application, the communication system supporting sensing measurement can also be referred to as a sensing system, or a communication and sensing system.

[0094] It should be noted that the communication system using the present application is only an example, and the communication system and communication scenario suitable for the present application are not limited thereto. The communication system and communication scenario provided in the present application do not cause any limitation on the solutions of the present application. In this case, the following will not be described in detail.

In the present application, the sensing node can refer to an entity having a sensing function and / or a sensing fusion function, for example, a terminal or a radio access network device. In addition to the sensing node, the plurality of nodes can also include other nodes having only a communication function, such as at least one of a sensing function (SF) network element, a mobile management network element, a location management network element, or a network storage network element (not shown in FIG. 1).

[0096] In a possible implementation, the plurality of nodes can include a first node and a second node. Optionally, the plurality of nodes can also include a third node.

[0109] As shown in FIG. 2, a flowchart of a communication awareness method provided by the embodiments of the present application is shown, which includes the following steps:

[0110] S101, the third node sends first information to the first node. Correspondingly, the first node receives the first information from the third node.

[0111] Optionally, the first node can be an entity with awareness function and communication function, and the first node can receive and measure awareness signals or receive and measure communication signals. The first node can support awareness measurement in any of the above awareness modes. For example, the first node can be a terminal, an access network device, etc. In the present application, the communication signal can refer to a signal used for communication, and the awareness signal can refer to a signal used for awareness. The communication signal and the awareness signal can be the same reference signal, or can be different reference signals.

[0112] Optionally, the third node can be a node capable of controlling the sending of the first information to other nodes (such as the first node), and the third node can be a sensing node without sensing function, but a communication device with communication function, for example, the third node can be an access network device or an SF network element, etc., without limitation. On this basis, the first node can receive the first information sent from the access network device, or the first node can receive the first information sent from the SF network element.

[0113] The first information is used to assist the first node in performing sensing measurement, and / or configure a triggering condition; the triggering condition is used to trigger the first node to report a measurement report, and the measurement report includes or is used to indicate a measurement quantity obtained by the first node through sensing measurement.

[0114] Optionally, the first node can be an entity with sensing function and communication function, for example, it can be a terminal, an access network device, an SF network element (or a sensing network element), etc. The third node can be a node capable of controlling the sending of the first information to other nodes (such as the first node), and the third node can be a sensing node without sensing function, but a communication device with communication function, for example, an access network device, an SF network element, etc., without limitation. On this basis, the first node can receive the first information sent from the access network device, or the first node can receive the first information sent from the SF network element.

[0115] Optionally, the first information can be carried in the first signaling. The first signaling can be any one of the following signaling: system information block (SIB), master information block (MIB), broadcast message, radio resource control (RRC) signaling, paging message, medium access control (MAC)-control element (CE), downlink control information (DCI) signaling, physical downlink control channel (PDCCH), physical downlink share channel (PDSCH), channel status information reference signal (CIS-RS), de-modulation reference signal (DMRS), tracking reference signal (TRS), paging message, short message; or the first signaling can also be in any new signal, channel or signaling, which is not limited.

[0116] Optionally, in the case that the first information is carried in the RRC signaling, the first information can be carried in the MeasObjectNR signaling in the RRC signaling.

[0117] Optionally, in the case that the first information is used to assist the first node in performing the sensing measurement, the first information further includes or indicates one or more of the following 1-6, wherein the information in the following 1-6 can be referred to as assistance information.

[0118] 1. sensing resource

[0119] The sensing resource can be a time-frequency resource of the sensing signal.

[0120] In other words, the sensing resource is a time-frequency resource used by the first node to receive the sensing signal, which is used to carry / transmit the sensing signal. In this application, the time-frequency resource can include time domain resource and / or frequency domain resource.

[0121] In the present application, the sensing signal received by the first node can be a sensing signal from the second node, i.e., the second node transmits the sensing signal, and the first node receives the sensing signal transmitted by the second node. The time-frequency resource used by the first node to receive the sensing signal can be understood as the time-frequency resource used by the second node to transmit the sensing signal. Optionally, the first node can receive the sensing signal in a self-transmitting and self-receiving sensing mode, in which case the first node and the second node are the same node. Alternatively, the first node can also receive the sensing signal in a non-self-transmitting and non-self-receiving mode, in which case the sensing signal received by the first node is from a node other than the first node, such as the second node, in which case the first node and the second node are different nodes.

[0122] For example, the first node is a terminal, and the second node is a base station. The sensing signal received by the first node can be a sensing signal received in a base station-transmitting and terminal-receiving sensing mode. For another example, the first node is a base station, and the second node is a terminal. The sensing signal received by the first node can be a sensing signal received in a terminal-transmitting and base station-receiving sensing mode.

[0123] It should be noted that the sensing signal transmitted by the second node to the first node can be a sensing signal generated by the second node itself, in which case the second node is the source node of the sensing signal, or it can also be a sensing signal transmitted by another node and received by the second node, in which case, with respect to the node that transmits the sensing signal to the second node, the second node can be referred to as the receiving node of the sensing signal. Specifically, the second node can be a terminal, an access network device, etc. The second node can be the same as the third node, such as the second node and the third node both being access network devices, etc.

[0124] In one example, the first information can carry / included identification information of the sensing resource, to directly indicate the sensing resource through the identification information of the sensing resource. In another example, the first information can carry information associated with the sensing resource / associated with the sensing resource, to indirectly indicate the sensing resource through the information, such as the first information can include / carry information of the sensing signal (such as an identifier or an index of the sensing signal), the information of the sensing signal being the information associated with the sensing resource, and the association between the information of the sensing signal and the sensing resource can indirectly indicate the time-frequency resource used by the first node to receive the sensing signal.

[0125] 2. Measurement purpose

[0126] The measurement purpose is used to indicate sensing or communication of the first node, i.e., the measurement purpose is used to indicate whether the purpose of the measurement of the first node is sensing or communication.

[0127] Optionally, the first node can perform sensing and communication based on the same reference signal, and for the same reference signal, the measurement purpose is different, and the corresponding measurement quantity is different. For example, the first information can indicate the measurement purpose by 1 bit; for example, when the 1 bit is 1, it indicates sensing, and when the 1 bit is 0, it indicates communication; or, when the 1 bit is 0, it indicates sensing, and when the 1 bit is 1, it indicates communication.

[0128] 3. The second node receives an expected time of receiving the echo signal corresponding to the sensing signal.

[0129] The expected time refers to a preset time of receiving the echo signal corresponding to the sensing signal by the second node. The expected time can be reported by the second node to the third node, or determined by the third node according to the sensing result of the second node, or the expected time can be agreed in advance, such as defined by a network protocol; or the expected time can be indicated by the third node to the second node; or the expected time can be a default between the first node and the third node, and is not limited.

[0130] The second node can be a sensing node that is currently sensing. Optionally, the second node can be a source node of the sensing signal, or the second node can be a receiving node of the sensing signal, or the second node can be a self-sensing and self-receiving sensing node.

[0131] The related description of the second node is as described above, and will not be repeated here.

[0132] 4. The first node receives a time range of the echo signal corresponding to the sensing signal.

[0133] It should be noted that the second node transmits the sensing signal, the sensing signal is reflected by the sensing target, and the first node receives the sensing signal reflected by the sensing target. The sensing signal can be referred to as an echo signal corresponding to the sensing signal. Here, it is uniformly described, and will not be repeated below.

[0134] Optionally, the time range of the first node receiving the echo signal corresponding to the sensing signal can be [-Δ1, +Δ2]. On this basis, the first node can detect the sensing signal in the time range [T0-Δ1, T0+Δ2], T0 is the expected time of the second node receiving the echo signal corresponding to the sensing signal. Wherein, Δ1 and Δ2 are uncertain values, Δ1 and Δ2 can be adjusted according to actual conditions, and are not limited. For example, Δ1 and Δ2 can be the same or different, or Δ1 and Δ2 can be independently configured, or Δ1 and Δ2 can be determined by the first node according to the trigger condition and the threshold, etc., and are not limited. For examples of trigger conditions and thresholds, refer to the following embodiments, which will not be described in detail here.

[0135] 5、a power difference between a transmission power of the sensing signal and a transmission power of the communication signal.

[0136] It should be noted that the current power difference is mainly used to represent the power difference between the transmission powers of the reference signals, such as the power difference between the transmission power of the non-zero-power (NZP) CSI-RS and the transmission power of the synchronization reference signal, which can be -3dB, 0dB, 3dB, or 6dB; or the power difference between the transmission power of the communication signal and the transmission power of the reference signal, such as the power difference between the transmission power of the PDSCH resource element (RE) and the transmission power of the NZP CSI-RS, which can be -8dB to 15dB.

[0137] Since the sensing signal has a large power variation and requires different energy consumption from the communication signal, the sensing signal needs a larger power range and finer power control accuracy. In addition, due to the requirements of network deployment, the coverage ranges of communication and sensing are different, resulting in inconsistent power ranges. Therefore, the first information needs to configure the power difference between the transmission power of the sensing signal and the transmission power of the communication signal, and the first node can determine the path loss relationship of the sensing channel and the communication channel based on the reception strength of the communication signal, the reception strength of the sensing signal, and the transmission power difference between the sensing signal and the communication signal, or the first node can determine the transmission power of the sensing signal based on the transmission power of the communication signal and the power difference between the transmission power of the sensing signal and the transmission power of the communication signal, and then perform sensing based on the transmission power of the sensing signal.

[0138] In the present application, the above-mentioned communication signal can include signals on PDSCH, signals on PDCCH, synchronization signal / physical layer broadcast channel block (SSB (or SS / PBCH block)), or CIS-RS, etc., without limitation.

[0139] 6、a transmission power of the sensing signal.

[0140] In other words, the first information can directly configure the transmission power of the sensing signal, and the first node can determine the path loss of the sensing channel based on the transmission power of the sensing signal, further determine the path loss relationship between the sensing channel and the communication channel, or the first node performs sensing based on the transmission power of the sensing signal.

[0141] Optionally, in the case where the first information is used to configure the triggering condition, the triggering condition includes one or more of the following:

[0142] a、a sensing node selection condition

[0143] The sensing node selection condition is used to select the available sensing node.

[0144] Optionally, the sensing node selection condition is used to select the available node, including: in the case that the sensing signal received by the first node satisfies the sensing node selection condition, the first node is an available sensing node; in the case that the sensing signal received by the first node does not satisfy the sensing node selection condition, the first node is an unavailable sensing node.

[0145] b. Sensing node switching / reselection condition

[0146] The sensing node switching / reselection condition is used to switch / reselect the available sensing node.

[0147] Optionally, the sensing node switching / reselection condition is used to switch / reselect the available sensing node, including: in the case that the sensing signal received by the first node satisfies the sensing node switching / reselection condition, switching / reselecting from the first node to other available sensing node; in the case that the sensing signal received by the first node does not satisfy the sensing node switching / reselection condition, not switching / reselecting other available sensing node.

[0148] The available sensing node can be a receiving node of the sensing signal, a sending node of the sensing signal, or a sensing node that spontaneously sends and receives, etc., without limitation.

[0149] c. Communication-sensing resource multiplexing condition

[0150] The communication-sensing resource multiplexing condition is used to indicate communication-sensing resource multiplexing. The communication-sensing multiplexing can refer to communication and sensing multiplexing the same time domain resource, frequency domain resource, space domain resource, code domain resource, or power domain resource. The communication-sensing resource multiplexing condition is used to indicate that the communication-sensing resource multiplexing can include: in the case that the communication-sensing resource multiplexing condition is satisfied, the communication-sensing resource can be multiplexed, and vice versa, in the case that the communication-sensing resource multiplexing condition is not satisfied, the communication-sensing resource cannot be multiplexed.

[0151] Optionally, the communication-sensing resource multiplexing condition includes: the sensing resource satisfies the communication requirement; or the communication resource satisfies the sensing requirement; or the sensing resource satisfies the communication requirement, and the communication resource satisfies the sensing requirement.

[0152] Optionally, in the case that the sensing resource satisfies the communication requirement, the first node multiplexes the sensing resource for sensing and communication. In the case that the communication resource satisfies the sensing requirement, the first node multiplexes the communication resource for sensing and communication. In the case that the sensing resource satisfies the communication requirement, and the communication resource satisfies the sensing requirement, the first node can multiplex the sensing resource for sensing and communication, or can multiplex the communication resource for sensing and communication, etc., without limitation.

[0153] The specific index of the communication requirement can be a communication capacity. In an example, the communication requirement can refer to a communication capacity under a signal-to-noise ratio (SNR) corresponding to the perceived signal received by the first node, or a communication capacity of a bandwidth corresponding to the perceived signal received by the first node. In this case, the perceived resource meeting the communication requirement means that the communication capacity provided by the perceived resource meets the demand of the communication service.

[0154] The perception requirement refers to a key performance indication (KPI) corresponding to the perception, and can specifically include a distance resolution, a distance unambiguous range, a speed resolution, a speed unambiguous range, an angle resolution, an angle unambiguous range, and the like. In this case, the communication resource meeting the perception requirement means that the KPI corresponding to the communication resource meets the demand of the perception service.

[0155] Examples of specific contents of the trigger condition can be referred to the following embodiments, which are not described in detail herein.

[0156] S102, the first node performs a perception measurement according to the first information, and obtains a measurement report.

[0157] Optionally, the measurement report can include a measurement quantity value (such as a received signal time, a received perceived signal strength, a perceived channel CQI value, and the like) obtained by performing the perception measurement using the auxiliary information included or indicated by the first information, and can further include or indicate one or more of the following: an indication that the perceived signal received by the first node meets the perception node selection condition; an indication that the perceived signal received by the first node meets the perception node switching / reselection condition; an indication that the perception resource of the first node meets the communication requirement; an indication that the communication resource of the first node meets the perception requirement, and the like, without limitation.

[0158] S103, the first node reports the measurement report. Correspondingly, the third node receives the measurement report from the first node.

[0159] Optionally, in the case where the first information is used to configure the trigger condition, the first node reports the measurement report in the case where the trigger condition is met.

[0160] In the case where the third node is an access network device, the first node reports the measurement report to the access network device, and correspondingly, the access network device receives the measurement report from the first node. In the case where the third node is an SF network element, the first node reports the measurement report to the SF network element, and correspondingly, the SF network element receives the measurement report from the first node.

[0161] Optionally, the measurement report can be carried in the second signaling. The second signaling can be carried in any one of the following signaling: a physical uplink shared channel (PUSCH), a physical uplink control channel (PUCCH), or the second signaling can also be carried in any new signal, channel or signaling, which is not limited.

[0162] It can be understood that the measurement report corresponding to different trigger conditions is different, and the following lists several cases of measurement report corresponding to different trigger conditions.

[0163] Case 1: the trigger condition includes a sensing node selection condition.

[0164] Optionally, in the case that the sensing signal received by the first node satisfies the sensing node selection condition, the measurement report indicates that the sensing signal received by the first node satisfies the sensing node selection condition, or the measurement report indicates the measurement value corresponding to the sensing signal received by the first node satisfying the sensing node selection condition. For examples of the measurement value corresponding to the sensing node selection condition, reference can be made to the following embodiments, which will not be described here.

[0165] Correspondingly, in the case that the sensing signal received by the first node does not satisfy the sensing node selection condition, the measurement report indicates that the sensing signal received by the first node does not satisfy the sensing node selection condition, or the measurement report indicates the measurement value corresponding to the sensing signal received by the first node not satisfying the sensing node selection condition.

[0166] Case 2: the trigger condition includes a sensing node switching / reselection condition.

[0167] Optionally, in the case that the sensing signal received by the first node satisfies the sensing node switching / reselection condition, the measurement report indicates that the sensing signal received by the first node satisfies the sensing node switching / reselection condition, or the measurement report indicates the measurement value corresponding to the sensing signal received by the first node satisfying the sensing node switching / reselection condition. For examples of the measurement value corresponding to the sensing node switching / reselection condition, reference can be made to the following embodiments, which will not be described here.

[0168] Correspondingly, in the case that the sensing signal received by the first node does not satisfy the sensing node switching / reselection condition, the measurement report indicates that the sensing signal received by the first node does not satisfy the sensing node switching / reselection condition, or the measurement report indicates the measurement value corresponding to the sensing signal received by the first node not satisfying the sensing node switching / reselection condition.

[0169] Case 3: the trigger condition includes a sensing resource multiplexing condition.

[0170] Optionally, in the case that the sensing-communication resource multiplexing condition comprises that the sensing resource meets the communication requirement, the measurement report indicates that the sensing resource of the first node meets the communication requirement, or the measurement report indicates a communication capacity value of the first node multiplexing the sensing resource for communication.

[0171] Correspondingly, in the case that the sensing-communication resource multiplexing condition comprises that the sensing resource does not meet the communication requirement, the measurement report indicates that the sensing resource of the first node does not meet the communication requirement, or the measurement report indicates a measurement value of the sensing resource of the first node not meeting the communication requirement.

[0172] Optionally, in the case that the sensing-communication resource multiplexing condition comprises that the communication resource meets the sensing requirement, the measurement report indicates that the communication resource of the first node meets the sensing requirement, or the measurement report indicates a sensing KPI corresponding to the communication resource of the first node meeting the sensing requirement, such as distance resolution, distance unambiguous range, speed resolution, speed unambiguous range, angle resolution, angle unambiguous range, etc., without limitation. For example, in this scheme, the measurement report can indicate the sensing KPI corresponding to the communication resource of the first node meeting the sensing requirement through a bitmap. For example, the measurement report comprises a bitmap, the bitmap comprises at least one bit, one bit corresponds to one sensing KPI, and the value of the bit is used to indicate whether the sensing KPI corresponding to the bit meets the sensing requirement. For example, the bitmap comprises three bits, and the value of each bit is used to indicate whether the distance dimension, speed dimension, and angle dimension meet the requirement, and each dimension comprises two sensing KPIs, such as resolution and unambiguous range. For example, the bitmap is 011, which respectively represents the distance dimension, speed dimension, and angle dimension. The 011 bit can indicate that the distance dimension does not meet the sensing requirement, the speed dimension and the angle dimension meet the sensing requirement; or the 011 bit can also indicate that the distance dimension meets the sensing requirement, the speed dimension and the angle dimension do not meet the sensing requirement, without limitation.

[0173] For another example, the bitmap comprises six bits, and the value of each bit is used to indicate whether the distance resolution, distance unambiguous range, speed resolution, speed unambiguous range, angle resolution, and angle unambiguous range meet the requirement. For example, the bitmap is 000111, which respectively represents that the distance resolution, distance unambiguous range, and speed resolution do not meet the requirement, and the speed unambiguous range, angle resolution, and angle unambiguous range meet the requirement; or the bitmap 000111 can also represent that the distance resolution, distance unambiguous range, and speed resolution meet the requirement, and the speed unambiguous range, angle resolution, and angle unambiguous range do not meet the requirement.

[0174] Correspondingly, in the case that the sensing resource reuse condition includes that the communication resource does not meet the sensing requirement, the measurement report indicates that the communication resource of the first node does not meet the sensing requirement, or the measurement report indicates that the sensing KPI corresponding to the case that the communication resource of the first node does not meet the sensing requirement, such as distance resolution, speed resolution or angle resolution, etc.

[0175] It should be noted that the measurement report can include any one of the above cases 1-case 3, or can include a combination of one or more of the above cases 1-case 3, which is not limited.

[0176] Optionally, on the basis of the above S102, the method can further include: in the case that the triggering condition is not met, the first node does not report the measurement report to the third node. Correspondingly, the third node does not receive the measurement report.

[0177] Or, in the case that the triggering condition is not met, the first node sends a negative acknowledgement message to the third node, which is used to indicate that the first node does not meet the triggering condition for sensing the corresponding measurement report. Correspondingly, the third node receives the negative acknowledgement message from the first node. Optionally, the negative acknowledgement message can be a(negative acknowledgement, NACK) message.

[0178] In this scheme, in the case that the triggering condition is not met, the measurement report is not reported, which can save signaling resources. In the case that the triggering condition is not met, the negative acknowledgement message is sent, which can ensure the robustness of the communication sensing scheme.

[0179] Optionally, the method further includes: in the case that the triggering condition is not met, the first node deletes the first information, and does not report the measurement report to the third node. On this basis, optionally, in the case that the third node does not receive the measurement report within a preset time period, the third node deletes the first information.

[0180] Or, in the case that the triggering condition is not met, the first node deletes the first information, and sends a negative acknowledgement message to the third node. On this basis, optionally, in the case that the third node receives the negative acknowledgement message from the first node, the third node deletes the first information.

[0181] S104, the third node determines a scheduling strategy according to the measurement report.

[0182] Optionally, the scheduling strategy includes at least one or more of the following:

[0183] The third node selects the first node for sensing. For example, the third node selects the first node as a cooperative sensing node of the second node / third node, or the third node selects the first node for self-sensing.

[0184] The third node switches / reselects other available sensing nodes for sensing. For example, the third node switches / reselects other available sensing nodes to be collaborative sensing nodes with the second / third node, or switches / reselects other available sensing nodes for spontaneous and self-receiving sensing.

[0185] The third node instructs the reuse of communication resources for sensing and communication. For example, the third node instructs the first node, and / or the second node, and / or the third node to reuse communication resources for sensing and communication.

[0186] The third node instructs the reuse of sensing resources for communication and sensing. For example, the third node instructs the first node, and / or the second node, and / or the third node to reuse sensing resources for communication and sensing.

[0187] The third node can be different from the second node, or it can be the same as the second node.

[0188] It should be noted that the third node's switching / reselection of other available sensing nodes as a cooperative sensing node for itself / the second node depends on the connection status of the first node. For example, if the first node is in Radio Resource Control (RRC) idle mode (i.e., the first node is in an RRC idle state or an RRC inactive state), then the third node will reselect other available sensing nodes as a cooperative sensing node for itself / the second node. If the first node is in connected mode (i.e., the first node is in an RRC connected state or an RRC active state), then the third node will switch other available sensing nodes as cooperative sensing nodes for itself / the second node.

[0189] In one implementation, when the third node selects the first node for sensing, the willingness of the first node needs to be considered. Specifically, whether the first node is willing to act as a collaborative sensing node with the second / third node, or whether the first node is willing to spontaneously initiate sensing. Optionally, if the measurement report reported by the first node indicates that the sensing node selection criteria are met, then the first node is assumed to be willing to perform sensing.

[0190] When the third node is the same as the second node, the third node can be the node that sends / receives sensing signals, and the first node assists the third node in sensing; when the third node is different from the second node, the second node can be the node that sends / receives sensing signals, and the first node cooperates with the second node in collaborative sensing.

[0191] For ease of description, the following example will be used to illustrate whether the first node should perform collaborative perception with the third node. This will be explained in a unified manner here and will not be repeated below.

[0192] Optionally, after receiving the first information from the third node, the first node can determine whether to perform cooperative sensing with the third node. Before determining to perform cooperative sensing with the third node, the first node can measure the sensing signal according to the first information.

[0193] For example, the first node performing cooperative sensing with the third node can mean that the first node performs sensing in the sensing area of the third node. In other words, the first node participates in the sensing service performed by the third node, or the third node assists the first node in performing sensing.

[0194] Optionally, the first node can determine whether to perform cooperative sensing with the third node according to the sensing accuracy requirement. For example, the sensing accuracy requirement can be predetermined, such as being specified by a protocol. Alternatively, the sensing accuracy requirement can be indicated by the third node (such as the SF network element) to the first node, such as the third node indicating the sensing accuracy requirement through the first information. Alternatively, the sensing accuracy requirement can be a default between the first node and the third node.

[0195] For example, the first node can determine whether to perform cooperative sensing with the third node according to the remaining resources of the first node. For example, if the remaining resources of the first node are insufficient to support cooperative sensing with the third node, the first node can refuse to perform cooperative sensing with the third node, and in this case, the first node can ignore the first information. If the remaining resources of the first node are sufficient to support cooperative sensing with the third node, the first node can perform cooperative sensing with the third node, and in this case, the first node can perform sensing according to the first information.

[0196] Optionally, the first node can feed back the determination result to the third node, to indicate whether to perform cooperative sensing with the third node. For example, the first node can send feedback information to the third node. Correspondingly, the third node receives the feedback information from the first node. The feedback information is used to indicate whether the first node performs cooperative sensing with the third node.

[0197] For example, the feedback information can be represented by 1 bit. When the 1 bit is 1, it means that the first node performs cooperative sensing with the third node. When the 1 bit is 0, it means that the first node refuses to perform cooperative sensing with the third node. Alternatively, when the 1 bit is 0, it means that the first node performs cooperative sensing with the third node. When the 1 bit is 1, it means that the first node refuses to perform cooperative sensing with the third node.

[0198] Optionally, the first node can send acknowledgement (ACK) information to the third node to indicate that the first node performs cooperative sensing with the third node, and the feedback information is the ACK information. Correspondingly, the first node can send NACK information to the third node to indicate that the first node refuses to perform cooperative sensing with the third node, and the feedback information is the NACK information.

[0199] Optionally, the first node can also indicate whether the first node performs cooperative sensing with the third node by whether the feedback information is sent. For example, the first node sends the feedback information to the third node to indicate that the first node performs cooperative sensing with the third node. Alternatively, the first node does not send the feedback information to the third node to indicate that the first node refuses to perform cooperative sensing with the third node, and if the third node does not receive the feedback information, it is considered that the first node refuses to perform cooperative sensing.

[0200] Based on the scheme, the first node can receive the first information, and since the first information includes the assistance information for assisting the first node in performing the sensing measurement, the continuity of the sensing service is ensured, and thus the sensing accuracy and the communication efficiency can be improved. In addition, the first information is also used to configure the triggering condition, the measurement report feedback can be performed according to the triggering condition, and the sensing failure probability can be reduced and the resource waste can be reduced.

[0201] Further, since the triggering condition includes the sensing node selection condition and the sensing node switching / reselection condition, the measurement report can be reported when the first node senses that the corresponding measurement report meets the sensing node selection condition and the sensing node switching / reselection condition, and the available sensing node can be more effectively selected, switched / reselected, and the sensing accuracy can be improved. In addition, since the triggering condition includes the communication-sensing resource multiplexing condition, the first node can be instructed to perform communication-sensing resource multiplexing when the first node senses that the corresponding measurement report meets the communication-sensing resource multiplexing condition, and thus the sensing accuracy and the communication efficiency can be improved, and the resource utilization rate can be improved.

[0202] The overall flow of the communication-sensing method is described above, and the specific application of the flow is described in detail below. The communication-sensing method provided by the embodiments of the present application can be applied to the following three scenarios.

[0203] The first scenario: the communication system includes a first node, a third node, and a sensing target. The third node is an entity with sensing function and communication function, such as an access network device, an SF network element, etc. The sensing target is a passive object, i.e., does not have data processing capability.

[0204] As shown in FIG. 3, a flowchart of a communication sensing method provided by an embodiment of the present application is shown. The method flowchart can be understood as a specific application of the method shown in FIG. 2. For example, referring to FIG. 3, the method includes the following steps:

[0205] S201, the third node sends first information to the first node. Correspondingly, the first node receives the first information from the third node.

[0206] Optionally, in the case that the third node is an access network device, the access network device can carry the first information in any one or more of RRC signaling, MAC-CE signaling, and DCI signaling. Of course, the access network device can also carry the first information in other new signaling or channels, which are not limited.

[0207] Optionally, in the case that the third node is an SF network element, the third node can carry the first information in non-access stratum (NAS) signaling or RRC signaling. Of course, the SF network element can also carry the first information in other new signaling or channels, which are not limited.

[0208] S202, the third node sends a sensing signal. Correspondingly, the sensing signal is reflected / scattered / diffracted by the sensing target, and the first node receives the sensing signal reflected / scattered / diffracted by the sensing target, which can be referred to as a corresponding echo signal of the sensing signal.

[0209] Optionally, in the case that the sensing function of the third node is self-generation and self-reception, the third node receives the corresponding echo signal of the sensing signal. Optionally, the third node can detect the corresponding echo signal of the sensing signal, sense the sensing target, and obtain the position, speed, and other information of the sensing target.

[0210] S203, the first node performs sensing measurement according to the first information, and obtains a measurement report.

[0211] S204, the first node reports the measurement report to the third node. Correspondingly, the third node receives the measurement report from the first node.

[0212] S205, the third node determines a scheduling strategy according to the measurement report.

[0213] It should be noted that the example of S201-S205 can refer to the related description of S101-S104 described above, which will not be repeated here.

[0214] Optionally, in the case that the triggering condition comprises the sensing node selection condition, the triggering condition satisfies the corresponding measurement report indicating that the sensing signal received by the first node satisfies the sensing node selection condition. In this case, the scheduling strategy comprises that the third node selects the first node as the cooperative sensing node of the third node. In this scheme, the third node selects the first node as the cooperative sensing node of the third node, and the third node and the first node cooperatively sense, so that the sensing accuracy can be improved.

[0215] Optionally, in the case that the triggering condition comprises the communication-sensing resource multiplexing condition, the triggering condition satisfies the corresponding measurement report indicating that the first node performs communication-sensing resource multiplexing. In this case, the scheduling strategy comprises that the third node indicates that the sensing resource of the first node satisfies the communication requirement; and / or, the third node indicates that the communication resource of the first node satisfies the sensing requirement.

[0216] In this embodiment, as shown in FIGS. 4, 5 and 6, an application scenario schematic diagram of the communication-sensing method provided by the embodiment of the present application can be understood as a specific application of the method flow shown in FIG. 3.

[0217] In the case that the triggering condition comprises the sensing node selection condition, the triggering condition satisfies the corresponding measurement report indicating that the sensing signal received by the first node satisfies the sensing node selection condition. On this basis, the scheduling strategy comprises that the third node selects the first node as the cooperative sensing node of the third node. Optionally, referring to FIG. 4, the third node can sense the sensing target through the link 1, and the first node assists the third node to sense as the cooperative sensing node of the third node. For example, the first node senses the sensing target through the link 2. Optionally, the third node and the first node can also communicate through the link 3.

[0218] In this scheme, the first node cooperatively senses as the cooperative sensing node of the third node, so that the sensing accuracy can be improved.

[0219] In the case that the triggering condition comprises the sensing node switching / reselection condition, the triggering condition satisfies the corresponding measurement report indicating that the sensing signal received by the first node satisfies the sensing node switching / reselection condition. On this basis, the scheduling strategy comprises that the third node switches / reselects from the first node to other available sensing nodes as the cooperative sensing node of the third node. In this scheme, the third node indicates to switch / reselect from the first node to other available sensing nodes as the cooperative sensing node of the third node, and cooperatively senses with the third node, so as to ensure the continuity of the sensing service.

[0220] In the case that the triggering condition comprises the communication-sensing multiplexing condition, the triggering condition satisfies the corresponding measurement report instruction to communicate the sensing resource multiplexing. On this basis, the scheduling strategy comprises the first node, and / or, the second node, and / or, the third node to communicate the sensing resource multiplexing. Exemplarily, as shown in FIG. 5, the third node senses the sensing target by communicating data through the link 4, and the first node receives the communication data through the link 5, thereby improving the communication rate of the first node. At this time, the communication-sensing multiplexing condition is satisfied, for example, the communication resource of the link 5 satisfies the sensing requirement, or the sensing resource corresponding to the link 4 satisfies the communication requirement.

[0221] Or, as shown in FIG. 6, the third node communicates and senses through the link 6, and the first node communicates and senses through the link 7. At this time, the communication-sensing multiplexing condition is satisfied, for example, the communication resource of the link 7 satisfies the sensing requirement, or the sensing resource corresponding to the link 6 satisfies the communication requirement.

[0222] In this scheme, the third node and the first node simultaneously sense and communicate, which can improve the sensing accuracy while improving the communication efficiency.

[0223] Secondly, the communication system comprises the first node, the second node, the third node and the sensing target. The second node is another sensing node different from the third node, and the second node is an entity with sensing function, such as a terminal, an access network device, an SF network element, a transmission reception point (TRP), etc. The third node is an entity capable of controlling the sending of the first information to the first node, and the third node is not a node for sending / receiving sensing signals, or the third node does not have sensing function, such as an access network device, an SF network element, etc. The sensing target is a passive object, i.e., without data processing capability.

[0224] As shown in FIG. 7, it is a flowchart of a communication-sensing method provided by an embodiment of the present application, and the method flow can be understood as another specific application of the method shown in FIG. 2. Exemplarily, referring to FIG. 7, the method comprises the following steps:

[0225] S301, the third node sends the first information to the first node. Correspondingly, the first node receives the first information from the third node.

[0226] For the illustration of S301, reference can be made to the related description of S201 above, which will not be repeated here.

[0227] S302, the second node sends the sensing signal. Correspondingly, the sensing signal is reflected by the sensing target, and the first node receives the sensing signal reflected by the sensing target, which can be referred to as the echo signal corresponding to the sensing signal.

[0228] Optionally, in the scenario that the sensing function of the second node is self-sensing and self-receiving, the second node receives the echo signal corresponding to the sensing signal. Optionally, the second node detects the echo signal corresponding to the sensing signal, senses the sensing target, and obtains the speed, position, and the like of the sensing target.

[0229] S303, the first node performs sensing measurement according to the first information, and obtains a measurement report.

[0230] S304, the first node reports the measurement report to the third node. Correspondingly, the third node receives the measurement report from the first node.

[0231] S305, the third node determines a scheduling strategy according to the measurement report.

[0232] It should be noted that for the example of S301-S305, the related description of S101-S104 can be referred to, and details are not repeated here.

[0233] The third kind: the communication system includes a first node and a third node. The third node is an entity with sensing function and communication function, such as a terminal, an access network device, an SF network element, and the like. The first node is an entity with sensing function, and the first node is a sensing target, that is, the first node is an active object with data processing capability, such as a terminal, an access network device, and the like.

[0234] As shown in FIG. 8, it is a flow diagram of a communication sensing method provided by an embodiment of the application. The method flow can be understood as another specific application of the method shown in FIG. 2. For example, referring to FIG. 8, the method includes the following steps:

[0235] S401, the third node sends first information to the first node. Correspondingly, the first node receives the first information from the third node.

[0236] For the example of S401, the related description of S201 can be referred to, and details are not repeated here.

[0237] S402, the third node sends a sensing signal. Correspondingly, the first node receives the sensing signal from the third node.

[0238] S403, the first node performs sensing measurement according to the first information, and obtains a measurement report.

[0239] S404, the first node reports the measurement report to the third node. Correspondingly, the third node receives the measurement report from the first node.

[0240] S405, the third node determines a scheduling strategy according to the measurement report.

[0241] It should be noted that for the illustration of S401-S405, reference can be made to the related description of S101-S104, which will not be repeated here.

[0242] The application scenarios of the communication sensing method provided by the embodiments of the present application are described above, and the triggering conditions will be described in detail below taking the first scenario as an example.

[0243] For example, as shown in FIG. 9, it is assumed that the sending time of the sensing signal 1 sent by the third node is x1, and the sending time of the sensing signal 2 sent by the third node is x2. Correspondingly, the receiving time of the echo signal corresponding to the sensing signal 1 received by the third node is T0, the receiving time of the echo signal corresponding to the sensing signal 1 received by the first node is T1, and the receiving time of the echo signal corresponding to the sensing signal 2 received by the first node is T2. Among them, the receiving time T1 and the receiving time T2 can be the same or different, and FIG. 9 takes the receiving time T1 and the receiving time T2 as an example for illustration.

[0244] Optionally, in the case that the triggering condition includes the sensing node selection condition, the sensing node selection condition includes one or more of the following three situations: Situation 1, the arrival time of the sensing signal is not later than a preset time; Situation 2, the receiving strength of the sensing signal is greater than or equal to a preset strength threshold; and Situation 3, the first time of the sensing signal is less than or equal to a preset time threshold. Wherein, the first time of the sensing signal is used to represent the distance between the first node and the sensing target.

[0245] For Situation 1, the arrival time of the sensing signal can be understood as the time when the sensing signal arrives at the first node, i.e., the time when the first node receives the sensing signal. For example, in the scenario shown in FIG. 9, the arrival time of the sensing signal can be understood as the time when the echo signal corresponding to the sensing signal arrives at the first node, i.e., the time when the first node receives the sensing signal. For example, the time when the first node receives the echo signal corresponding to the sensing signal 1 (i.e., T1), or the time when the first node receives the echo signal corresponding to the sensing signal 2 (i.e., T2).

[0246] In this Situation 1, the arrival time of the sensing signal not later than the preset time can be understood as the arrival time of the sensing signal being less than or equal to the preset time. Taking the time when the first node receives the echo signal corresponding to the sensing signal 1 (i.e., T1) as the arrival time of the sensing signal as an example, the arrival time of the sensing signal not later than the preset time can be expressed as T1≤ preset time. Optionally, the preset time can be set as T0, or other time, which is not limited.

[0247] Taking a preset time T0 as an example, in an example, in a case where T1≤T0, the first node receives the echo signal corresponding to the sensing signal 1 faster, which indicates that the first node is closer to the sensing target than the third node, and the first node has a higher possibility of having an advantage in sensing, and the first node can be selected as the cooperative sensing node of the third node to perform sensing. Therefore, in the case where T1≤T0, the measurement report can indicate that the sensing signal received by the first node satisfies the sensing node selection condition, such as directly indicating T1≤T0 in the measurement report; or the measurement report can indicate the measurement value corresponding to the sensing node selection condition that the sensing signal received by the first node satisfies, such as directly indicating T1 in the measurement report.

[0248] For case 2, the reception strength of the sensing signal can be understood as the reception strength of the sensing signal received by the first node. In the scenario shown in FIG. 9, the reception strength of the sensing signal can be understood as the reception strength of the echo signal corresponding to the sensing signal received by the first node. For example, the reception strength of the echo signal corresponding to the sensing signal 1 received by the first node, or the reception strength of the echo signal corresponding to the sensing signal 2 received by the first node, or the minimum reception strength or average reception strength of the plurality of sensing signal reception strengths.

[0249] In this case 2, the reception strength of the sensing signal is greater than or equal to a preset strength threshold, which indicates that the reception strength of the sensing signal received by the first node is high, and the sensing capability of the first node is good, and the first node can be selected as the cooperative sensing node of the third node to perform sensing. Therefore, in the case where the reception strength of the sensing signal (which can be understood as the average or minimum value in the sensing period) is greater than the preset strength threshold, the measurement report can indicate that the sensing signal received by the first node satisfies the sensing node selection condition, such as directly indicating in the measurement report that the reception strength of the sensing signal is greater than the preset strength threshold; or the measurement report can indicate the measurement value corresponding to the sensing node selection condition that the sensing signal received by the first node satisfies, such as directly indicating the reception strength of the sensing signal in the measurement report.

[0250] For case 3, in an example, the first time of the sensing signal is the difference between the time when the echo signal corresponding to the sensing signal arrives at the first node and the time when the echo signal corresponding to the sensing signal arrives at the third node. In the scenario shown in FIG. 9, the time when the echo signal corresponding to the sensing signal 1 arrives at the first node, i.e., the arrival time (i.e., T1) of the echo signal corresponding to the sensing signal 1 received by the first node. The time when the echo signal corresponding to the sensing signal 1 arrives at the third node, i.e., the arrival time (i.e., T0) of the echo signal corresponding to the sensing signal 1 received by the third node. On this basis, the above case 3 can be represented as: T1-T0≤a preset time threshold.

[0251] In an example corresponding to the case 3, T1-T0 can reflect the difference between the distance from the first node to the sensing target and the distance from the third node to the sensing target. T1-T0≤a preset time threshold (which can be 0, for example) can indicate that the first node is closer to the sensing target than the third node, and the first node can have a greater advantage in sensing. The first node can be selected as the cooperative sensing node of the third node to perform sensing. Therefore, in the case of T1-T0≤the preset time threshold, the measurement report can indicate that the sensing signal received by the first node satisfies the sensing node selection condition, such as the measurement report directly indicating T1-T0≤the preset time threshold; or the measurement report can indicate the measurement value corresponding to the sensing node selection condition that the sensing signal received by the first node satisfies, such as the measurement report directly indicating T1-T0.

[0252] For case 3, in another example, the first time of the sensing signal is the sum of the difference between the time at which the echo signal corresponding to the sensing signal arrives at the first node and the time at which the echo signal corresponding to the sensing signal arrives at the third node and the time for the first node to process the sensing signal. For example, in the scenario shown in FIG. 9, the time at which the echo signal corresponding to the sensing signal 1 arrives at the first node is the time at which the first node receives the echo signal corresponding to the sensing signal 1 (i.e., T1). The time at which the echo signal corresponding to the sensing signal 1 arrives at the third node is the time at which the third node receives the echo signal corresponding to the sensing signal 1 (i.e., T0). On this basis, the above case 3 can be expressed as:

[0253] T1-T0+C1≤a preset time threshold. Wherein C1 is used to represent the time for the first node to process the sensing signal.

[0254] Wherein, the time for the first node to process the sensing signal refers to the time required by the first node to calculate the position, speed, and other information of the sensing target. Similarly, the time for the first node to report the channel state information (CSI) to the third node, that is, the minimum time for the first node to report the measurement report to the third node is the time for the first node to process the sensing signal.

[0255] Optionally, the time for the first node to process the sensing signal can be indicated by the third node to the first node (such as being indicated by the first information or being indicated by other indication information, which is not limited); or it can be specified by a protocol; or it can be determined by the first node, which is not limited.

[0256] In the case that the first node processes the sensing signal at the time indicated by the third node, exemplary, since the first node processes the sensing signal of different levels at different times, the first node first reports the capability information of the first node to the third node, indicating the time corresponding to the first node processing the sensing signal of each level. On this basis, after the third node sends the sensing signal, the third node indicates the time corresponding to the first node processing the sensing signal of the corresponding level.

[0257] The time of each level can include the time of the first level information, the time of the second level information, the time of the third level information, and the time of the fourth level information. Optionally, the time of the first level information indicates the time of obtaining the channel matrix through channel estimation; the time of the second level information indicates the time of calculating the distance / speed / angle information; the time of the third level information indicates the time of obtaining the specific position (such as latitude and longitude) of the sensing target; and the time of the fourth level information indicates the time of the sensing target identification result, the sensing event judgment result, and the environment reconstruction result.

[0258] In another example corresponding to the case 3, T1-T0 can reflect the difference between the distance from the first node to the sensing target and the distance from the third node to the sensing target. T1-T0+C1 can reflect the delay degree of the first node processing the sensing signal. T1-T0+C1

[0259] For case 3, in another example, the first time of the sensing signal is the time when the echo signal corresponding to the sensing signal arrives at the first node. Exemplary, in the scenario shown in FIG. 9, the time when the echo signal corresponding to the sensing signal 1 arrives at the first node, i.e., the time (T1) when the first node receives the echo signal corresponding to the sensing signal 1. On this basis, the above-mentioned case 3 can be represented as T1

[0260] In this case, the measurement report can indicate that the perceived signal received by the first node satisfies the measurement value corresponding to the perceived node selection condition, such as the measurement report directly indicating T1.

[0261] Optionally, in the case that the triggering condition comprises the perceived node switching / reselection condition, the perceived node switching / reselection condition comprises one or more of the following three cases: case 4: the arrival time corresponding to the perceived signal is later than a preset time; case 5: the received strength of the perceived signal is less than or equal to a preset strength threshold; and case 6: the first time of the perceived signal is greater than or equal to a preset time threshold.

[0262] It should be noted that, in the case that the perceived signal received by the first node satisfies the perceived node selection condition, the first node is an available perceived node, i.e., the first node can serve as a cooperative perceived node of the third node for perception. In other words, the perceived node selection condition is a condition for the first node to enter the perception service. In the case that the perceived signal received by the first node satisfies the perceived node switching / reselection condition, other perceived nodes can be switched / reselected as the cooperative perceived nodes of the third node. In other words, the perceived node switching / reselection condition is a condition for the first node to exit the perception service.

[0263] For example, with reference to the above perceived node selection condition, case 4 can be represented as T1≥T0; case 5 can be represented as the received strength of the perceived signal being less than or equal to a preset strength threshold; and case 6 can be represented as T1-T0≥a preset time threshold; or T1-T0+C1≥a preset time threshold, or T1≥a preset time threshold, and the preset time threshold can be set as T0. For the three cases of the perceived node switching / reselection condition, reference can be made to the related descriptions of the three cases of the perceived node selection condition, which will not be repeated here.

[0264] Optionally, the preset time, the preset strength threshold, and the preset time threshold related to the perceived node selection condition can be the same as or different from the preset time, the preset strength threshold, and the preset time threshold related to the perceived node switching / reselection condition, which is not limited.

[0265] Optionally, the preset time, the preset strength threshold, and the preset time threshold related to the perceived node selection condition, and the preset time, the preset strength threshold, and the preset time threshold related to the perceived node switching / reselection condition can be specified by a protocol; or can be indicated by the third node to the first node; or can be default between the third node and the first node, which is not limited.

[0266] In a case where the third node indicates the preset time threshold, the preset intensity threshold, and the preset time threshold related to the sensing node selection condition and the preset time threshold, the preset intensity threshold, and the preset time threshold related to the sensing node switching / reselection condition, the first information further indicates the preset time threshold, the preset intensity threshold, and the preset time threshold related to the sensing node selection condition; and / or, the preset time threshold, the preset intensity threshold, and the preset time threshold related to the sensing node switching / reselection condition.

[0267] Optionally, in a case where the triggering condition comprises the common sensing resource multiplexing condition, the common sensing resource multiplexing condition comprises: the sensing resource satisfies the communication requirement; and / or, the communication resource satisfies the sensing requirement.

[0268] In an example, the sensing resource satisfying the communication requirement comprises at least one or more of the following:

[0269] 1. A communication capacity estimated according to the sensing signal is greater than or equal to a preset threshold.

[0270] 2. A difference between a communication capacity estimated according to the sensing signal and a communication capacity estimated according to the communication signal is greater than or equal to a preset threshold.

[0271] The error rate threshold used for estimating the communication capacity according to the sensing signal is the same as the error rate threshold used for estimating the communication capacity according to the communication signal; or, the error rate threshold used for estimating the communication capacity according to the sensing signal is an extremely low error rate threshold.

[0272] Optionally, the communication capacity comprises a continuous quality improvement (CQI) index or a modulation and coding scheme (MCS) index.

[0273] Optionally, the error rate threshold may be, for example, 0.1 or 0.00001, and is not limited thereto. The extremely low error rate threshold may be, for example, 0.00001, and is not limited thereto.

[0274] In this scheme, in a case where the communication capacity estimated according to the sensing signal is greater than or equal to a preset threshold, or a difference between the communication capacity estimated according to the sensing signal and the communication capacity estimated according to the communication signal is greater than or equal to a preset threshold, it indicates that the communication capacity corresponding to the sensing link is higher than the communication capacity of the communication link, or the communication capacity corresponding to the sensing link is reduced less than the communication capacity corresponding to the communication link, and thus the sensing resource satisfies the communication requirement.

[0275] 3. The difference between the received intensity of the sensing signal and the received intensity of the communication signal, and the difference between the power of the sensing signal and the power of the communication signal, is greater than or equal to a preset intensity threshold.

[0276] 4. The difference between the air interface transmission data of the sensing signal and the air interface transmission time of the communication signal is less than a preset time threshold.

[0277] Optionally, the preset time threshold can be determined according to the cyclic prefix (CP) length and the time of receiving the sensing signal, to ensure that the communication signal and the sensing signal are orthogonal in the time domain.

[0278] In another example, the communication resource meets the sensing requirement, including at least one or more of the following:

[0279] 1. The communication resource meets the range resolution or the range unambiguous range when used for sensing.

[0280] Optionally, the communication resource meets the range resolution or the range unambiguous range when used for sensing, including: the frequency domain resource of the communication signal is greater than or equal to the frequency domain resource of the sensing signal, such as the bandwidth of the communication signal being greater than or equal to the bandwidth of the sensing signal; and / or, the subcarrier spacing (SCS) of the communication signal is less than the subcarrier spacing of the sensing signal.

[0281] 2. The communication resource meets the speed resolution or the speed unambiguous range when used for sensing.

[0282] Optionally, the communication resource meets the speed resolution or the speed unambiguous range when used for sensing, including: the speed resolution of the communication signal is greater than or equal to the speed resolution of the sensing signal; or, the speed unambiguous range of the communication signal is greater than or equal to the speed unambiguous range of the sensing signal.

[0283] For example, the speed resolution of the communication signal = 1 / (FC1*Nf1*Tsym1); the speed resolution of the sensing signal = 1 / (FC2*Nf2*Tsym2).
