Abstract
Description
Technical Field
[0001] This application relates to the field of communication technology, specifically to a sensing method and corresponding device. Background Technology
[0002] In many sensing scenarios, sensing measurements rely on sensing resources. As the sensing scenario dynamically changes, the demand for sensing resources during the measurement process also changes dynamically. This is especially true for user equipment (UE-based) sensing measurements, where the UE initiates the sensing request and processes the sensing data. In this scenario, UE sensing measurements are even more dependent on the sensing resource configuration of network equipment.
[0003] During the process of configuring sensing resources for a UE, the surrounding environment and the UE's sensing needs both influence the resource requirements for sensing measurements. However, in UE-based sensing scenarios, network devices cannot know the environment being sensed or the sensing needs. Therefore, the sensing resources configured by the network device for the UE often do not meet the UE's sensing requirements. Insufficient resource configuration can easily lead to wasted resources and sensing failures; while sufficient resource configuration can easily lead to redundant resource waste.
[0004] Therefore, how to configure appropriate sensing resources for UE has become an urgent technical problem to be solved. Summary of the Invention
[0005] This application provides a sensing method to improve the matching degree between sensing resources and sensing needs, and reduce resource waste. This application also provides corresponding apparatus, computer-readable storage media, and computer program products.
[0006] This application provides a sensing method applied to a first communication device. The first communication device can be a terminal device, a component within the terminal device responsible for communication and / or sensing functions (e.g., a processor, circuit, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the first communication device. Wherein, if the component responsible for communication and / or sensing functions is a chip, the chip can be a modem chip (also known as a baseband chip), a system-on-chip (SoC) chip containing a modem core, or a system-in-package (SIP) chip. The method includes: sending first information to a second communication device, the first information indicating at least one reference information for adjusting sensing resources, the at least one reference information being obtained based on sensing measurements of the first sensing resources; and receiving information from the second communication device regarding second sensing resources, the second sensing resources being determined based on the at least one reference information, the second sensing resources being used for sensing measurements.
[0007] In this application, the second communication device may be a network device or a terminal device, or a component (e.g., a processor, circuit, chip, or chip system) in the network device or terminal device that is responsible for communication and / or sensing functions, or a logic module or software that can realize all or part of the functions of the second communication device.
[0008] In this application, sensing resources refer to time-frequency resources used for sensing, such as resource blocks (RBs) or resource elements (REs).
[0009] In this application, reference information refers to the perception results obtained through perception measurement, as well as auxiliary information indicating the adjustment of perception resources based on perception needs.
[0010] In this application, the second perceptual resource refers to the perceptual resource after adjustment of the first perceptual resource.
[0011] In the first aspect described above, the first communication device can send at least one reference information to the second communication device based on sensing measurements performed using the first sensing resources. In this way, the second communication device can configure more suitable sensing resources for the first communication device based on the at least one reference information, thereby improving the matching degree between sensing resources and sensing needs and reducing resource waste.
[0012] In one possible implementation, at least one reference information includes adjustment information for at least one sensing metric related to the ranging task and / or velocity measurement task; the at least one sensing metric includes at least one of the following: signal-to-noise ratio (SNR), resolution, unambiguity, or accuracy.
[0013] In this application, signal-to-noise ratio (SNR) refers to the ratio of signal power to noise power, usually expressed in decibels (dB). The higher the SNR, the better the signal quality.
[0014] In this application, resolution refers to the smallest interval in the imaging result that can distinguish adjacent targets, such as distance interval or angular interval, which determines the fineness of the imaging and the target discrimination ability.
[0015] In this application, unambiguity, also known as non-ambiguity, refers to the range within which the imaging results will not produce confusion or repetition when measuring distance, angle, and speed. It is used to ensure the accuracy and reliability of the measurement and avoid confusion and misunderstanding of target information.
[0016] In this application, precision and error are relative concepts. Error means inaccuracy or imprecision, that is, the degree to which the measurement result deviates from the true value. The larger the error, the lower the precision; the smaller the error, the higher the precision.
[0017] It should be noted that the perception metrics in this application are not limited to the four listed above, but may also include other metrics that may be involved in the perception process, such as signal-to-interference-plus-noise ratio (SINR).
[0018] In this possible implementation, by indicating the adjustment information of at least one sensing index related to the ranging task and / or speed measurement task through the first information, the second communication device can quickly and accurately determine the second sensing resource based on the adjustment amount of at least one sensing index, thereby improving the adaptability of the sensing resource to the ranging task and / or speed measurement task.
[0019] In one possible implementation, at least one reference information includes adjustment information for at least one resource parameter related to the ranging task and / or velocity measurement task; the at least one resource parameter includes at least one of the following: signal power, bandwidth, signal measurement duration, time-domain resource density, or frequency-domain resource density.
[0020] In this application, signal power affects SNR or accuracy, bandwidth affects resolution or accuracy, signal measurement duration affects the resolution of speed measurement task, time-domain resource density affects the unambiguity of speed measurement task, and frequency-domain resource density affects the unambiguity of ranging task.
[0021] In this application, the time-domain resource density is used to indicate the number of REs that are uniformly distributed in the time-domain direction corresponding to the first subcarrier, where the first subcarrier is any subcarrier in the resource block.
[0022] In this application, the frequency domain resource density is used to indicate the number of REs that are uniformly distributed in the frequency domain direction corresponding to the first time domain symbol, where the first time domain symbol is any time domain symbol in the resource block.
[0023] In this possible implementation, by indicating the adjustment information of at least one resource parameter related to the ranging task and / or velocity measurement task through the first information, the second communication device can quickly and accurately determine the second sensing resource based on the adjustment amount of at least one resource parameter, thereby improving the adaptability of the sensing resource to the ranging task and / or velocity measurement task.
[0024] In one possible implementation, adjustment information of at least one sensing indicator is used to indicate the adjustment value and / or adjustment trend of the corresponding sensing indicator.
[0025] In this application, the adjustment value can represent the adjustment amount of the sensing index. Taking SNR as an example, if the SNR corresponding to the first sensing resource is "A" dB, the adjustment value of the SNR can be "B" dB. The value of B can be larger or smaller than the value of A. The adjustment amount can also represent an increase or decrease. The second communication device can increase or decrease the corresponding sensing index corresponding to the first sensing resource, such as increasing or decreasing "C" dB based on "A" dB.
[0026] In this application, the adjustment trend may include upward or downward adjustment, reduction or expansion, increment or difference, etc. The first information may indicate the scaling factor, which can be used to indicate the reduction or expansion factor.
[0027] In this possible implementation, by using first information to indicate the adjustment value and / or adjustment trend of the sensing index, the speed at which the second communication device determines the second sensing resource can be improved.
[0028] In one possible implementation, adjustment information for at least one resource parameter is used to indicate at least one of the following: adjustment value, adjustment trend, or adjustment threshold of the corresponding resource parameter.
[0029] In this application, the adjustment threshold can be the maximum or minimum value to be adjusted, and the second communication device can adjust within the range indicated by the adjustment threshold.
[0030] In this possible implementation, by using first information to indicate at least one of the adjustment value, adjustment trend, or adjustment threshold of the resource parameters, the speed at which the second communication device determines the second sensing resource can be improved.
[0031] In one possible implementation, sending the first information to the second communication device includes: sending the first information to the second communication device based on reporting conditions; wherein the reporting conditions include: receiving a first request from the second communication device, the first request being used to request the first information; a change in the sensing requirement or a change in the sensing result satisfying a first threshold; or, satisfying the reporting requirements of the second communication device.
[0032] In this possible implementation, the first communication device sends the first information to the second communication device only when the reporting conditions are met, which can reduce the waste of resources caused by frequently sending the first information.
[0033] In one possible implementation, the first information used to indicate at least one reference information for adjusting the perceived resources includes the first information used to indicate a set of suggested values, the set of suggested values including at least one reference information.
[0034] In this possible implementation, the set of suggested values can include multiple reference information, each including at least one reference information. For example, multiple suggested values can be provided for the second communication device to refer to for the same sensing index or the same resource parameter. This improves both the adaptability of the second sensing resource to the sensing requirements and the flexibility of the second communication device in determining the second sensing resource.
[0035] In one possible implementation, receiving information about a second sensing resource from a second communication device includes: receiving a set of sensing resource information from the second communication device, wherein the set of sensing resource information includes information about the second sensing resource.
[0036] In this application, the information of the second sensing resource can be a resource pattern of the second sensing resource, or indication information that determines the resource pattern of the second sensing resource. The sensing resource information set can include information of one or more sensing resources. This sensing resource information set can be a sensing resource information set initially configured for the first communication device to perform sensing measurements, or it can be a sensing resource set reconfigured to meet sensing requirements.
[0037] In this possible implementation, the second communication device can configure a set of sensing resources for the sensing and measurement process of the first communication device. This can reduce the possibility of interruption due to lack of available resources during the sensing and measurement process of the first communication device, and improve the continuity of sensing and measurement.
[0038] A second aspect of this application provides a sensing method applied to a second communication device. The second communication device can be a network device or a terminal device, or a component within the network device or terminal device responsible for communication and / or sensing functions (e.g., a processor, circuit, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the second communication device. The method includes: receiving first information from a first communication device, the first information indicating at least one reference information for adjusting sensing resources, the at least one reference information being obtained by the first communication device through sensing measurements based on the first sensing resources; and sending information about second sensing resources to the first communication device, the second sensing resources being determined based on the at least one reference information, and the second sensing resources being used by the first communication device for sensing measurements.
[0039] In the second aspect mentioned above, the second communication device can configure more suitable sensing resources for the first communication device based on at least one reference information sent by the first communication device, thereby improving the matching degree between sensing resources and sensing needs and reducing resource waste.
[0040] In one possible implementation, at least one reference information includes adjustment information for at least one sensing metric related to the ranging task and / or velocity measurement task; the at least one sensing metric includes at least one of the following: signal-to-noise ratio, resolution, unambiguity, or accuracy.

[0100] Integrated sensing and communication (ISAC) refers to a device (such as a terminal device or network device) transmitting wireless signals that simultaneously possess both sensing and communication capabilities. Communication requirements can be simply understood as sending information from the transmitter to the receiver. Sensing requirements can be simply understood as sensing the surrounding environment, the speed of moving objects, and / or distance, etc. ISAC is widely considered a key application scenario for next-generation wireless communication (e.g., 6th generation mobile communication technology, 6G). It is understandable that integrated sensing and communication can also be called joint communications and sensing (JCAS / ICAS), or simply integrated sensing and communication.
[0101] The technical solutions of this application embodiment can be applied to various communication systems, such as the Institute of Electrical and Electronics Engineers (IEEE) 802.15.4 standard and IEEE 802.11 standards (including standards identified as Wi-Fi technology), Bluetooth standard, Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), General Packet Radio Service (GPRS), Enhanced Data GSM Environment (EDGE), Terrestrial Trunked Radio (TETRA), Wideband-CDMA (W-CDMA), Evolution Data Optimized (EV-DO), 1×EV-DO, EV-DO Revision A, EV-DO Revision B, High Rate Packet Data (HRPD), High Speed Packet Access (HSPA), High Speed Downlink Packet Access (HSDPA), High Speed Uplink Packet Access (HSUPA), Evolved HSPA (HSPA+), Long Term Evolution (LTE).

[0102] Figure 1 This is a schematic diagram of the communication system provided in an embodiment of this application.
[0103] Figure 1The communication system shown is primarily a wireless communication system capable of communication, sensing, and / or positioning. This system may include the following components: mobile device 101; base station 102; satellite (also known as a space vehicle) 103; access point (AP) 104; wireless devices 105 (e.g., portable Wi-Fi 105-1, smartwatch (or wristband) 105-2, vehicle 105-3, mobile phone 105-4, laptop 105-5, static communication / positioning device); network 106; network function server 107; and external client 108. Generally, this communication system enables communication between mobile device 101 and other devices, positioning of mobile device 101 and / or other devices, sensing measurements performed by mobile device 101, and / or combinations thereof. For example, the communication system can estimate the location of the mobile device 101 based on the radio frequency signals received and / or transmitted by the mobile device 101 and the known locations of other components (e.g., satellites, base stations, access points) that transmit and / or receive the radio frequency signals. Additionally, sensing measurements can be performed using wireless devices such as mobile devices, base stations, and satellites (and / or other NTN platforms that can be implemented on aircraft, drones, balloons, etc.). For example, sensing measurements of one or more target objects can be performed using radio frequency signals transmitted by one or more wireless devices. For example, sensing measurements of one or more target objects can be performed using radio frequency signals received by one or more wireless devices.
[0104] Combination Figure 1 Mobile device 101 can access network 106 via base station using the first communication link 110 to send and receive information with network-connected devices (such as network function server 107). Mobile device 101 can also access network 106 via AP using the second communication link 130 to send and receive information with network-connected devices (such as network function server 107). Mobile device 101 can use the third communication link 120 to communicate with other devices 105.
[0105] It should be noted that Figure 1 Only general diagrams of various components are provided. You may use some or all of them as needed, or copy a specific component. For example, although... Figure 1Only one mobile device 105 is shown, but it should be understood that many terminal devices (e.g., hundreds, thousands, millions, etc.) can use this communication system. Similarly, the communication system can include more than Figure 1 The number of base stations 102 and / or APs 104 may be greater or less than shown. Figure 1 The connections between the various components shown include data and signaling connections, which may include additional (intermediate) components, direct or indirect physical and / or wireless connections, and / or additional networks. Furthermore, components may be rearranged, combined, separated, replaced, and / or omitted depending on the desired functionality. In some implementations, for example, an external client 108 may connect directly to the network function server 107. Those skilled in the art will recognize numerous modifications to the illustrated components.
[0106] While ground components such as access points (APs) and base stations can be fixed, this is not the case in some implementations. Mobile components can be used. For example, in some implementations, the location of mobile device 101 can be estimated, at least in part, based on measurements of radio frequency signals transmitted between mobile device 101 and one or more other mobile devices 105 (which can be mobile or fixed). Figure 1 As shown, other mobile devices may include, for example, a portable Wi-Fi device 105-1, a smartwatch (or wristband) 105-2, a vehicle 105-3, a mobile phone 105-4, a laptop computer 105-5, a static communication / positioning device, or other static and / or mobile devices capable of providing wireless signals for locating mobile device 101, or combinations thereof. Wireless signals from mobile device 105 for locating mobile device 101 may include RF signals using, for example, Bluetooth, IEEE 802.11x (e.g., Wi-Fi), Ultra Wideband (UWB), IEEE 802.15x, or combinations thereof. Mobile device 105 may additionally or alternatively use non-RF wireless signals (such as a camera) to locate mobile device 101, such as infrared signals or other optical technologies.
[0107] Network 106 may include any of a variety of wireless and / or wired networks. Network 106, for example, may include any combination of public and / or private networks, local area networks (LANs) and / or wide area networks (WANs). Furthermore, the network may utilize one or more wired and / or wireless communication technologies. In some implementations, the network may, for example, include cellular or other mobile networks, wireless local area networks (WLANs), wireless wide area networks (WWANs), and / or the Internet.
[0108] Network function server 107 may include one or more servers and / or other computing devices configured to provide network management and / or network auxiliary functions. For example, a location server may determine a location estimate for a mobile device and / or provide data (e.g., “auxiliary data”) to mobile device 105 to facilitate location measurement and / or location determination. In some implementations, the location server may also include an enhanced serving mobile location center (E-SMLC) that uses a control plane (CP) location solution for LTE radio access for mobile devices to support mobile device positioning. The location server may also include a location management function (LMF) that supports the positioning of mobile devices using the control plane location solution for NR or LTE radio access.
[0109] A network function server can also be used as a sensing measurement server. A sensing measurement server can be used to coordinate and / or assist in coordinating the sensing measurements of one or more wireless devices within a system on one or more target objects. Wireless devices may include mobile devices, base stations, access points (APs), other mobile devices, satellites, or any combination thereof. Wireless devices capable of performing sensing measurements may be referred to herein as "sensing measurement nodes." To perform sensing measurements, a sensing server can coordinate a sensing session during which one or more RF sensing measurement nodes can perform sensing measurements by transmitting radio frequency signals (e.g., a sensing reference signal (SeRS)) and measuring reflected signals or "echo signals." For example, reflected signals and object / target detection can be determined based on channel state information (CSI) received at a receiving device. To facilitate sensing measurements (e.g., within a sensing measurement session between one or more sensing measurement nodes), the sensing server can provide data (e.g., "auxiliary data") to the sensing measurement nodes to facilitate SeRS transmission and / or measurement, object / target detection, or any combination thereof. Such data may include a SeRS configuration indicating which resources (e.g., time and / or frequency resources) can be used (e.g., within the sensing measurement session) to transmit SeRS for sensing measurements. According to some embodiments, the sensing server may include a sensing management function (SMF).
[0110] External client 108 may be a web server or remote application associated with mobile device 101 (e.g., accessible to the user of mobile device 101), or a server, application, or computer system that provides location services to other users. This may include obtaining and providing the location of mobile device 101 (e.g., enabling services such as friend or relative finder, child or pet location). Alternatively or additionally, external client 108 may obtain the location of mobile device 101 and provide it to emergency service providers, government agencies, etc.
[0111] A base station can typically refer to a single physical transmission point located at a base station site or multiple co-located physical transmission points. A transmission reception point (TRP), also known as a transmission / reception point, corresponds to this type of transmission point. In some cases, a base station may include multiple TRPs, for example, each TRP being associated with a different antenna, antenna array, or antenna panel of the base station. As used herein, the transmission function of a TRP can be performed by a transmission point (TP), and / or the reception function of a TRP can be performed by a reception point (RP), which may be physically separate from or different from the TP. That is, a TRP may include both a TP and an RP. A physical transmission point may include the antenna array of a base station, for example, in the case of a multiple-input multiple-output (MIMO) system and / or where the base station employs beamforming. A base station (e.g., a gNB) may be able to transmit different “beams” in different directions and perform “beam scanning,” where signals are transmitted along different directions (e.g., one after another) in different beams.
[0112] A base station can also refer to multiple non-co-located physical transmission points. For example, a physical transmission point can be a distributed antenna system (DAS), which is a spatially separated antenna network connected to a common source via a transmission medium. Another example is a remote radio head (RRH), which is a remote base station connected to a serving base station.
[0113] APs can include Wi-Fi APs, Bluetooth APs, or APs with cellular capabilities (e.g., 4G LTE and / or 5G NR).
[0114] In some implementations, base stations can be owned, maintained, and / or operated by cellular network providers and can employ any of a variety of wireless technologies.
[0115] The satellite can be a satellite in a global navigation satellite system (GNSS) and / or an NTN satellite. GNSS includes the global positioning system (GPS), Galileo, BeiDou, etc.
[0116] Satellites can communicate with one or more base stations and / or one or more user equipment.
[0117] Satellites can be used for communication positioning in one or more ways. For example, a satellite can be part of GNSS. Positioning using RF signals from GNSS satellites can include measuring multiple GNSS signals at a GNSS receiver on a mobile device to perform highly accurate positioning, such as carrier-based positioning. Alternatively or concurrently, satellites can be used for NTN-based positioning; in other words, functionally, satellites can operate as a TRP (or TP) of a network (e.g., LTE and / or NR networks). Specifically, reference signals transmitted by NTN satellites are similar to those transmitted by base stations and are coordinated by a network function server, which can then operate as a location server. In some implementations, the satellites used for NTN-based positioning can be different from those used for GNSS-based positioning. In some implementations, NTN nodes can include non-ground vehicles such as aircraft, balloons, drones, etc., which can supplement or replace NTN satellites. NTN satellites and / or other NTN platforms can be further utilized to perform sensing measurements.

[0121] 3. Sensing signal: A signal that can realize the sensing function. For example, if signal A is reflected or scattered during transmission and the resulting signal B can be used for sensing, then signal A (or signal B) has the sensing function. Therefore, signal A (or signal B) can be called a sensing signal.
[0122] 4. Echo signal (ES): refers to the signal obtained after reflection or scattering. The sensing result can be determined by measuring the echo signal; the echo signal can be received by beamforming.

Different beams can be considered different resources. The beam used to transmit signals can be called the transmission beam (Txbeam), and the beam used to receive signals can be called the reception beam (Rxbeam). The transmission beam refers to the distribution of signal strength in different directions in space after the signal is transmitted through the antenna, while the reception beam refers to the distribution of signal strength in different directions in space of the wireless signal received from the antenna.

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

[0128] Furthermore, terminal devices can also be terminal devices in future communication systems beyond the fifth generation (5G) (such as 5G Advanced communication systems) or in future evolved public land mobile networks (PLMNs). For example, 5G Advanced networks can further expand the form and function of 5G communication terminals; 5G Advanced terminals include, but are not limited to, vehicles, cellular network terminals (integrating satellite terminal functions), drones, and Internet of Things (IoT) devices.

In the embodiments of this application, the chip system can be composed of chips or can include chips and other discrete devices.
[0132] 7. Network Equipment: This can be equipment within a wireless network. For example, a network equipment can be a node (or device) that connects terminal devices to the wireless network; it can also be called a RAN node or RAN equipment. Currently, some examples of RAN equipment include: base stations (BS), evolved NodeBs (eNodeBs), gNBs (gNodeBs) in 5G communication systems, transmission reception points (TRPs), evolved Node Bs (eNBs), radio network controllers (RNCs), Node Bs (NBs), home base stations (e.g., home evolved Node Bs, or home Node Bs (HNBs), base band units (BBUs) or wireless fidelity (Wi-Fi) access points (APs), terminals that function as base stations in device-to-device (D2D) communication, satellites, drones, unmanned spacecraft, communication balloons, and other non-ground equipment. In addition, in one network architecture, network devices may include central unit (CU) nodes, distributed unit (DU) nodes, or RAN devices that include both CU and DU nodes.
[0133] Optionally, the RAN node can also be a macro base station, micro base station, indoor station, relay node, donor node, or a radio controller in a cloud radio access network (CRAN) scenario. The RAN node can also be a server, wearable device, vehicle, or in-vehicle equipment. For example, the access network equipment in vehicle-to-everything (V2X) technology can be a roadside unit (RSU).
[0134] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, with different RAN nodes each implementing some of the base station's functions. For example, RAN nodes can be CUs, DUs, CUs (control plane, CP), CUs (user plane, UP), or radio units (RUs). CUs and DUs can be set up separately or included in the same network element, such as a baseband unit (BBU). RUs can be included in radio equipment or radio units, such as remote radio units (RRUs), active antenna units (AAUs), radio heads (RHs), or remote radio heads (RRHs).
[0135] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an open access network (open RAN, O-RAN, or ORAN) system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software modules and hardware modules.
[0136] Communication between access network devices and terminal devices follows a specific protocol layer structure.

[0143] In this embodiment of the application, the network device can also be a network node with sensing capabilities, which can provide sensing services for terminal devices or other network devices. The network node can sense the sensing target by sending sensing signals or receiving echo signals.
[0144] It is understood that a base station can be referred to as a communication device. For example, a base station can be understood as a device with base station functions. For example, the device used to implement the functions of a base station can be a base station itself; or some components within a base station, such as CU, DU, etc. It can also be a device capable of supporting the base station in implementing this function, such as a chip system, hardware circuit, software module, or hardware circuit plus software module, which can be installed in a base station or used in conjunction with a base station. In the embodiments of this application, the chip system can be composed of chips or can include chips and other discrete devices.
[0145] 8. The terms "system" and "network" in the embodiments of this application can be used interchangeably. "Multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the related objects before and after are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, "at least one of A, B, and C" includes A, B, C, AB, AC, BC, or ABC. And, unless otherwise specified, the ordinal numbers such as "first" and "second" mentioned in the embodiments of this application are used to distinguish multiple objects and are not used to limit the order, sequence, priority, or importance of multiple objects.
[0146] 9. In the embodiments of this application, "send" and "receive" indicate the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX, which may include sending via the air interface. "Receive information from YY" can be understood as the source of the information being YY, which may include receiving from YY via the air interface. "Send" can also be understood as the "output" of the chip interface, and "receive" can also be understood as the "input" of the chip interface.
[0147] In other words, sending and receiving can occur between devices, such as between network devices and terminal devices, or within a device, such as between components, modules, chips, software modules, or hardware modules within the device via buses, wiring, or interfaces.
[0148] It is understandable that information may undergo necessary processing, such as encoding and modulation, between the source and destination, but the destination can understand the valid information from the source. Similar statements in this application can be interpreted in a similar way and will not be elaborated further.
[0149] 10. In the embodiments of this application, "instruction" may include direct instruction and indirect instruction, as well as explicit instruction and implicit instruction. The information indicated by a certain piece of information (hereinafter referred to as instruction information) is called the information to be instructed. In the specific implementation process, there are many ways to indicate the information to be instructed, such as, but not limited to, directly indicating the information to be instructed, such as the information to be instructed itself or its index. It can also indirectly indicate the information to be instructed by indicating other information, where there is an association between the other information and the information to be instructed; or it can only indicate a part of the information to be instructed, while the other parts of the information to be instructed are known or pre-agreed upon. For example, the instruction of specific information can be achieved by using a pre-agreed (e.g., protocol predefined) arrangement order of various information, thereby reducing the instruction overhead to a certain extent. This application does not limit the specific method of instruction. It is understood that for the sender of the instruction information, the instruction information can be used to indicate the information to be instructed; for the receiver of the instruction information, the instruction information can be used to determine the information to be instructed.

The following descriptions of the embodiments of this application do not constitute a limitation on the scope of protection of this application.
[0151] The sensing method provided in this application can be applied to single-base sensing scenarios or dual-base sensing scenarios.
[0152] In this context, a single-base sensing scenario refers to a scenario where the transmitting end of the sensing signal and the receiving end of the corresponding echo signal are the same communication device, or the transmitting and receiving ends are co-located in the same device. A single-base sensing scenario can also be called a transceiver integrated sensing scenario. For example... Figure 2A In the single-base sensing scenario shown, the first communication device sends a sensing signal and receives the echo signal reflected or scattered by the sensing target.
[0153] A dual-base sensing scenario refers to a scenario where the transmitting end of the sensing signal and the receiving end of the echo signal are not the same communication device; a dual-base sensing scenario can also be called a transceiver separation sensing scenario. For example... Figure 2B In the dual-base sensing scenario shown, the second communication device sends a sensing signal, and the first communication device receives the echo signal reflected or scattered by the sensing target.
[0154] The first communication device can be a terminal device or a network device, or a component within the terminal device or network device responsible for communication and / or sensing functions (e.g., a processor, circuit, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the first communication device. If the component responsible for communication and / or sensing functions is a chip, this chip can be a modem chip, also known as a baseband chip, or a system-on-a-chip (SoC) chip containing a modem core, or a system-in-package (SIP) chip.
[0155] The second communication device may be a network device or a terminal device, or a component (e.g., a processor, circuit, chip, or chip system) in a network device or terminal device that is responsible for communication and / or sensing functions, or a logic module or software that can realize all or part of the functions of the second communication device.
[0156] The target being perceived can be a static target or a moving target; a static target can be a stationary object such as a building, while a moving target refers to a moving object, such as a moving car, pedestrian, or drone.
[0157] The above Figure 2A In the single-base sensing scenario shown, the first communication device serves as both the transmitter of the sensing signal and the receiver of the echo signal. The above... Figure 2B In the illustrated dual-base sensing scenario, the second communication device is the transmitting end of the sensing signal, and the first communication device is the receiving end of the echo signal of the sensing signal. In scenarios based on terminal device sensing and measurement, the first communication device is usually a terminal device, and the second communication device can be a network device or a terminal device. Several sensing scenarios based on terminal device sensing and measurement are described below with reference to the accompanying drawings.
[0158] like Figure 2C As shown, a first communication device (e.g., a mobile phone) performs single-base sensing. The first communication device (e.g., a mobile phone) sends sensing signals and receives echo signals reflected or scattered by the sensing target (e.g., a car). Figure 2C The scenario shown may also include a second communication device (e.g., a network device), in which the second communication device (e.g., the network device) can configure sensing resources for the first communication device (e.g., a mobile phone). In this way, the first communication device (e.g., the mobile phone) can perform sensing measurements based on the sensing resources configured by the second communication device (e.g., the network device).
[0159] like Figure 2DAs shown, a first communication device (e.g., a mobile phone) and a second communication device (e.g., a drone) perform bi-base sensing. The second communication device (e.g., the drone) sends sensing signals, and the first communication device (e.g., the mobile phone) receives echo signals reflected or scattered by the sensed target (e.g., a car). Figure 2D The diagram illustrates a sidelink sensing scenario, where a second communication device (e.g., a drone) can configure sensing resources for a first communication device (e.g., a mobile phone). In this way, the first communication device (e.g., a mobile phone) can perform sensing measurements based on the sensing resources configured by the second communication device (e.g., a drone).
[0160] like Figure 2E As shown, a first communication device (e.g., a mobile phone) and a second communication device (e.g., a network device) perform bi-base sensing. The second communication device (e.g., the network device) sends a sensing signal, and the first communication device (e.g., the mobile phone) receives the echo signal reflected or scattered by the sensing target (e.g., a car). Figure 2E In the scenario shown, the second communication device (e.g., a network device) can configure sensing resources for the first communication device (e.g., a mobile phone). In this way, the first communication device (e.g., a mobile phone) can perform sensing measurements based on the sensing resources configured by the second communication device (e.g., the network device).
[0161] In this application, device A is a sensing signal transmitter, which can also be understood as including a sensing signal transmitter in device A, and device B is an echo signal receiver of the sensing signal, which can also be understood as including a sensing signal receiver in device B.
[0162] The sensing method provided in the embodiments of this application is described below from the perspective of a first communication device and a second communication device. For a description of the first or second communication device, please refer to the preceding text. Figures 2A to 2E Please refer to the relevant descriptions in the document for comprehension.
[0163] like Figure 3 As shown, the sensing method provided in this application includes:
[0164] S301. The first communication device sends first information to the second communication device. Correspondingly, the second communication device receives the first information.
[0165] The first information is used to indicate at least one reference information for adjusting the sensing resource, wherein the at least one reference information is obtained by sensing measurement based on the first sensing resource.
[0166] In this application, sensing resources refer to time-frequency resources used for sensing, such as resource blocks (RBs) or resource elements (REs).
[0167] In this application, reference information refers to the perception results obtained through perception measurement, as well as auxiliary information indicating the adjustment of perception resources based on perception needs.
[0168] In this application, the second perceptual resource refers to the perceptual resource after adjustment of the first perceptual resource.
[0169] S302. The second communication device sends information about the second sensing resource to the first communication device. Correspondingly, the first communication device receives the information about the second sensing resource.
[0170] In this application, the second sensing resource is determined based on at least one reference information, and the second sensing resource is used for sensing measurement.
[0171] In this embodiment of the application, the information of the second sensing resource may be a resource pattern of the second sensing resource, or indication information used to indicate the resource pattern of the second sensing resource.
[0172] The diagram of the second sensory resource can be found in [reference]. Figure 4A or Figure 4B To understand. For example Figure 4A As shown, taking an RB comprising 12 subcarriers and 14 time-domain symbols as an example, the three REs formed by time-domain symbol 3, carrier 0, subcarrier 4, and subcarrier 8 can represent the second sensing resource. Figure 4A The resource pattern shown can be understood as a resource pattern of the second sensed resource. Figure 4B In this context, the two REs formed by subcarrier 3 and time-domain symbol 3 and time-domain symbol 10 can represent the second sensing resource. Figure 4B The resource pattern shown can be understood as a resource pattern of the second sensed resource.
[0173] certainly, Figure 4A or Figure 4B This is just one possible example of information from a second-sensory resource. Information from a second-sensory resource can also be represented in other forms, and the resource pattern of a second-sensory resource is not limited to... Figure 4A or Figure 4B As shown in the figure.
[0174] In the solution provided in this application embodiment, the first communication device can send at least one reference information obtained by sensing measurement using the first sensing resources to the second communication device. In this way, the second communication device can configure more suitable sensing resources for the first communication device based on at least one reference information, thereby improving the matching degree between sensing resources and sensing needs and reducing resource waste.
[0175] The at least one reference information described in the above embodiments may include adjustment information for at least one perception index related to the ranging task and / or velocity measurement task; or, adjustment information for at least one resource parameter related to the ranging task and / or velocity measurement task.
[0176] At least one of the following perception metrics may include at least one of the following: signal-to-noise ratio (SNR), resolution, unambiguity, or accuracy.
[0177] In this application, signal-to-noise ratio (SNR) refers to the ratio of signal power to noise power, usually expressed in decibels (dB). The higher the SNR, the better the signal quality.
[0178] In this application, resolution refers to the smallest interval in the imaging result that can distinguish adjacent targets, such as distance interval or angular interval, which determines the fineness of the imaging and the target discrimination ability.
[0179] In this application, unambiguity, also known as non-ambiguity, refers to the range within which the imaging results will not produce confusion or repetition when measuring distance, angle, and speed. It is used to ensure the accuracy and reliability of the measurement and avoid confusion and misunderstanding of target information.
[0180] In this application, precision and error are relative concepts. Error means inaccuracy or imprecision, that is, the degree to which the measurement result deviates from the true value. The larger the error, the lower the precision; the smaller the error, the higher the precision.
[0181] It should be noted that the perception metrics in this application are not limited to the four listed above, but may also include other metrics that may be involved in the perception process, such as signal-to-interference-plus-noise ratio (SINR).
[0182] At least one resource parameter includes at least one of the following: signal power, bandwidth, signal measurement duration, time-domain resource density, or frequency-domain resource density.
[0183] The resource parameters in this application are related to the sensing task or sensing index, which may include ranging and / or velocity measurement tasks. The relationship between the resource parameters and the sensing task or sensing index can be understood by referring to Table 2, as shown in Table 2:
[0184] Table 2: Relationship between resource parameters and perception indicators
[0185]
[0186] Table 2 shows that signal power affects SNR in both ranging and velocity measurement tasks. In ranging tasks, bandwidth affects resolution; in velocity measurement tasks, signal measurement duration (also known as the velocity frame period) affects resolution. In ranging tasks, frequency domain resource density affects unambiguity; in velocity measurement tasks, wavelength or time domain resource density affects unambiguity. In ranging tasks, bandwidth or signal power affects accuracy; in velocity measurement tasks, signal measurement duration or signal power affects accuracy.
[0187] In this application, the time-domain resource density is used to indicate the number of REs uniformly distributed in the time-domain direction corresponding to the first subcarrier, where the first subcarrier is any subcarrier in the resource block. For example... Figure 4B In the resource pattern shown, the temporal resource density is 2.
[0188] In this application, frequency domain resource density is used to indicate the number of REs uniformly distributed in the frequency domain direction corresponding to the first time domain symbol, where the first time domain symbol is any time domain symbol in the resource block. For example... Figure 4A In the resource pattern shown, the frequency domain resource density is 3.
[0189] In the solution provided in this application embodiment, by indicating the adjustment information of at least one sensing index / at least one resource parameter related to the ranging task and / or speed measurement task through the first information, the second communication device can quickly and accurately determine the second sensing resource according to the adjustment amount of at least one sensing index / at least one resource parameter, thereby improving the adaptability of the sensing resource to the ranging task and / or speed measurement task.
[0190] The adjustment information of at least one of the perception indicators described above can be used to indicate the adjustment value and / or adjustment trend of the corresponding perception indicator.
[0191] In this application, the adjustment value can represent the adjustment amount of the sensing index. Taking SNR as an example, if the SNR corresponding to the first sensing resource is "A" dB, the adjustment value of the SNR can be "B" dB. The value of B can be larger or smaller than the value of A. The adjustment amount can also represent an increase or decrease. The second communication device can increase or decrease the corresponding sensing index corresponding to the first sensing resource, such as increasing or decreasing "C" dB based on "A" dB.
[0192] In this application, the adjustment trend may include upward or downward adjustment, reduction or expansion, increment or difference, etc. The first information may indicate the scaling factor, which can be used to indicate the factor of reduction or expansion.
[0193] The form of the adjustment information for at least one perception indicator can be understood by referring to Table 3, as shown in Table 3:
[0194] Table 3: Adjustment information for at least one perception indicator
[0195]
[0196] In the examples in Table 3, each sensing target can be indicated by 1 bit to indicate the adjustment trend. For example, SNR can be represented by a bit value "0" for upward adjustment and a bit value "1" for downward adjustment; of course, it can also be represented by a bit value "0" for downward adjustment and a bit value "1" for upward adjustment. This application does not limit this. The adjustment amount for upward or downward adjustment can be pre-agreed upon by the first and second communication devices, or it can be included in the adjustment information. For example, X1 can represent the adjustment amount for upward or downward adjustment. In this case, X1 can be understood by referring to "C" dB in the above examples. If the adjustment information does not include the adjustment trend but includes the adjustment value, then X1 in this case can be understood by referring to "B" dB in the above examples, representing the adjusted value.
[0197] Similarly, in scenarios involving scaling down or scaling up, such as SNR, a bit value of "0" can be used to represent scaling up, and a bit value of "1" can be used to represent scaling down.
[0198] Of course, a bit value of "0" can also be used to represent scaling down, and a bit value of "1" can be used to represent scaling up; this application does not limit this. The scaling amount can be pre-agreed upon by the first and second communication devices, or it can be included in the adjustment information, such as X1 representing the scaling amount. In this case, the adjustment value can be a scaling factor, such as scaling up by X1 times or scaling down by X1 times.
[0199] Similarly, in incremental or differential scenarios, such as SNR, the increment can be represented by a bit value "0" and the difference can be represented by a bit value "1".
[0200] Of course, a bit value of "0" can also be used to represent the difference, and a bit value of "1" can be used to represent the increment; this application does not limit this. The adjustment amount of the increment or difference can be pre-agreed upon by the first and second communication devices, or it can be included in the adjustment information, such as X1 representing the adjustment amount. In this case, the adjustment value can be the adjustment amount, such as increasing X1 or decreasing X1.
[0201] Additionally, for information on resolution, unambiguity, and accuracy, please refer to the introduction to SNR. If the first and second communication devices have pre-agreed on adjustment amounts, and the adjustment information is a bit sequence "0000", it can indicate an increase in SNR, resolution, unambiguity, and accuracy. Of course, the bit sequence "0000" can also indicate a decrease in each sensing index, depending on the meaning indicated by each bit value.
[0202] The form of the adjustment information for at least one perception indicator can be understood by referring to Table 4, as shown in Table 4:
[0203] Table 4: Adjustment information for at least one resource parameter
[0204]
[0205] In the example in Table 4, each resource parameter can be represented by 1 bit to indicate the adjustment trend. For example, signal power can be represented by a bit value "0" for upward adjustment and a bit value "1" for downward adjustment; of course, it can also be represented by a bit value "0" for downward adjustment and a bit value "1" for upward adjustment. This application does not limit this. The adjustment amount for upward or downward adjustment can be pre-agreed upon by the first and second communication devices, or it can be included in the adjustment information. For example, Y1 can represent the adjustment amount for upward or downward adjustment. If the adjustment information does not include the adjustment trend, Y1 can represent the value to which the signal power is adjusted. In addition, the adjustment information can also include an adjustment threshold TH1. If the adjustment information includes TH1, it means that the signal power can be adjusted below TH1 or above TH1, which is related to whether TH indicates the minimum or maximum value of the adjustment threshold.
[0206] Similarly, in scenarios involving scaling down or scaling up, such as signal power, a bit value "0" can represent scaling up and a bit value "1" can represent scaling down; of course, a bit value "0" can also represent scaling down and a bit value "1" can represent scaling up, and this application does not limit this. The scaling amount can be pre-agreed upon by the first and second communication devices, or it can be included in the adjustment information, such as Y1 representing the scaling amount. In this case, the adjustment value can be a scaling factor, such as scaling up by Y1 times or scaling down by Y1 times.
[0207] Similarly, in incremental or differential scenarios, such as signal power, a bit value "0" can represent the increment and a bit value "1" can represent the differential; of course, a bit value "0" can also represent the differential and a bit value "1" can represent the increment, and this application does not limit this. The adjustment amount of the increment or differential can be pre-agreed upon by the first and second communication devices, or it can be included in the adjustment information, such as Y1 representing the adjustment amount. In this case, the adjustment value can be the adjustment amount, such as increasing Y1 or decreasing Y1.
[0208] Additionally, the concepts of bandwidth, signal measurement duration, frequency domain resource density, and time domain resource density can be understood by referring to the introduction of signal power. If the first and second communication devices have pre-agreed on adjustment amounts, and the adjustment information is the bit sequence "00000," it can indicate an increase in signal power, bandwidth, signal measurement duration, frequency domain resource density, and time domain resource density. Of course, the bit sequence "00000" can also indicate a decrease in various sensing indicators, depending on the meaning indicated by each bit value.
[0209] Additionally, it should be noted that the meaning of the adjustment information may differ for ranging and velocity measurement tasks. For example, a ranging task may not include time-domain resource density, while a velocity measurement task may not include frequency-domain resource density. Of course, it could also be a ranging and velocity measurement task, in which case the bit sequence might be longer, and the first and second communication devices could pre-determine the meaning of each bit. Furthermore, the meaning of the aforementioned adjustment information is not limited to the same row in Table 3 or Table 4; the adjustment information can correspond to different rows of resource parameters. For example, the adjustment information may include one or more of the following:
[0210] Signal power adjustment ΔP that meets requirements ue It can also be 1 bit, used to indicate power + / -; where "+" indicates power increase and "-" indicates power decrease;
[0211] The threshold TH3 for the required signal measurement duration, including the maximum or minimum value;
[0212] The threshold TH5 for the temporal resource density required to meet the demand, including the maximum or minimum value;
[0213] The required signal bandwidth threshold TH2, including its maximum or minimum value; or,
[0214] The threshold TH4 for the required frequency domain resource density, including the maximum or minimum value.
[0215] The signal power in the embodiments of this application can be the signal transmission power.
[0216] The following example demonstrates how to adjust resource parameters:
[0217] 1. For ranging applications, the first communication device feeds back first information to the second communication device. The first information can be used to indicate at least one of the following resource parameters: the amount of signal power adjustment, the minimum or maximum value of bandwidth, and the minimum or maximum value of frequency domain resource density.
[0218] For example, if the sensing metrics determined based on the first sensing resource (such as accuracy, resolution, SNR, or at least one of unambiguity) do not meet the requirements, the first information may indicate the amount of signal power adjustment (e.g., +3dB), the minimum bandwidth (e.g., 100MHz), or the maximum frequency domain resource density (e.g., 2).
[0219] For example, if the sensing metrics determined based on the first sensing resource (such as at least one of accuracy, resolution, SNR, and unambiguity) exceed the requirements, the first information may indicate: the amount of signal power adjustment (e.g., -3dB), the maximum bandwidth (e.g., 100MHz), and the minimum frequency domain resource density (e.g., 2).
[0220] 2. For speed measurement applications, the first communication device feeds back first information to the second communication device. The first information can be used to indicate at least one of the following resource parameters: the adjustment amount of signal power, the minimum or maximum value of signal measurement duration, and the minimum or maximum value of time-domain resource density.
[0221] For example, if the sensing indicators determined based on the first sensing resources (such as accuracy, resolution, SNR, unambiguity, or at least one of these) do not meet the requirements, the first information can indicate: the adjustment amount of signal power (such as +3dB), the minimum value of signal measurement duration (such as 1s, 5 slots), and the maximum value of time-domain resource density (such as 2 time-domain symbol intervals, 2ms time interval).
[0222] For example, if the sensing metrics determined based on the first sensing resources (such as accuracy, resolution, SNR, unambiguity, or at least one of these) exceed the requirements, the first information can indicate: the amount of signal transmit power adjustment (e.g., -3dB), the maximum value of signal measurement duration (e.g., 1s, 5 slots), and the minimum value of time-domain resource density (e.g., 2 time-domain symbol intervals, 2ms time interval).
[0223] The sensing method provided in this application embodiment can have a variety of possible sensing processes, which will be described below.
[0224] like Figure 5 As shown, the first communication device is terminal device 1, and the second communication device can be a network device or terminal device 2. The sensing scenario is a dual-base sensing scenario. The sensing method provided in this application embodiment includes:
[0225] S501. The first communication device sends capability information to the second communication device. Correspondingly, the second communication device receives the capability information.
[0226] In this application, capability information may include the number, location, and orientation of antenna elements. These antenna elements may include those for transmitting signals or those for receiving signals. Capability information may also include time-frequency resource information, such as bandwidth, carrier frequency, and time slots.
[0227] S502. The first communication device sends a sensing measurement request to the second communication device. Correspondingly, the second communication device receives the sensing measurement request.
[0228] The sensing measurement request is used to request sensing resources from the second communication device.
[0229] S503. The second communication device sends a sensing resource configuration message to the first communication device. Correspondingly, the first communication device receives the sensing resource configuration message.
[0230] The sensing resource configuration message may include information about the first sensing resource configured by the second communication device for the first communication device, such as the resource pattern of the first sensing resource or the indication information of the resource pattern.
[0231] If the second communication device is a network device, the sensing resource configuration message can be a first radio resource control (RRC) message. If the second communication device is terminal device 2, the sensing resource configuration message can be a first proximity communication (PC) 5-RRC message.
[0232] The first sensory resource can be located in a first sensory resource set, which can also include other sensory resources of different sizes. Typically, different sensory resources in the same sensory resource set exhibit certain regularities, such as the temporal duration of different sensory resources increasing in a stepwise manner.
[0233] S504. The second communication device transmits a sensing signal based on the first sensing resource.
[0234] S505. The first communication device receives the echo signal based on the first sensing resource.
[0235] S506. The first communication device determines the sensing result based on the echo signal received from the first sensing resource, and determines the first information based on the sensing result.
[0236] The perception result can be the perception measurement result of the perceived target, such as: determining various perception indicators through perception measurement, such as: SNR, resolution, unambiguity or accuracy, etc.
[0237] The first communication device can determine at least one reference information that indicates the adjustment of sensing resources based on the actual measured sensing indicators and the sensing indicators required in practice.
[0238] S507. The first communication device sends first information to the second communication device. Correspondingly, the second communication device receives the first information.
[0239] The content of the first information can be understood by referring to the preceding introduction. For example, it may include at least one of the following: distance measurement SNR adjustment information that meets requirements; distance measurement resolution adjustment information that meets requirements; distance measurement unambiguity adjustment information that meets requirements; distance measurement accuracy adjustment information that meets requirements; speed measurement SNR adjustment information that meets requirements; speed measurement resolution adjustment information that meets requirements; speed measurement unambiguity adjustment information that meets requirements; or speed measurement accuracy adjustment information that meets requirements. Alternatively, the content of the first information may include a signal power adjustment amount ΔP that meets requirements. ue The threshold TH3 for signal measurement duration that meets the requirements, the threshold TH5 for time-domain resource density that meets the requirements, the threshold TH2 for signal bandwidth that meets the requirements, or the threshold TH4 for frequency-domain resource density that meets the requirements.
[0240] S508. The second communication device determines the second sensing resource based on the first information.
[0241] If the first set of sensing resources has sensing resources that meet the sensing requirements of the first communication device, then S509a is executed; if the first set of sensing resources does not have sensing resources that meet the sensing requirements of the first communication device, then S509b is executed.
[0242] S509a. The second communication device sends an activation message to the first communication device. Correspondingly, the second communication device receives the activation message.
[0243] The activation message is used to instruct the activation of the second sensory resource in the first sensory resource set.
[0244] The activation message can be sent via downlink control information (DCI) or sidelink control information (SCI).
[0245] S509b. The second communication device sends a sensing resource reconfiguration message to the first communication device. Correspondingly, the second communication device receives the sensing resource reconfiguration message.
[0246] If the second communication device is a network device, the sensing resource reconfiguration message can be a second RRC message. This second RRC message can instruct the second communication device to reconfigure a second set of sensing resources for the first communication device, the second set of sensing resources including those in an active state. If the second communication device is a network device, then for terminal device 2, the sensing resource reconfiguration message can be a second PC5-RRC.
[0247] The second RRC message or the second PC5-RRC message may include a set of sensing resource information, which may include information about the second sensing resource.
[0248] S510. If S509b is executed, the second communication device releases the sensing resources in the first sensing resource set.
[0249] S511. The first communication device and the second communication device re-perform sensing measurements based on the second sensing resource.
[0250] The S511 may include: a second communication device transmitting a sensing signal based on a second sensing resource, and a first communication device receiving an echo signal based on the second sensing resource.
[0251] Starting from S511, the above process from S506 to S510 can be repeated until the sensing measurement ends. However, the sensing result in S506 is obtained based on the echo signal received by different sensing resources each time.
[0252] From the above Figure 5 As described in the introduction, the first communication device can determine at least one reference information to instruct the adjustment of the first sensing resource based on the sensing results of the first sensing resource. In this way, the second communication device can configure more suitable sensing resources for the first communication device based on at least one reference information, thereby improving the matching degree between sensing resources and sensing needs and reducing resource waste.
[0253] like Figure 6 As shown, the first communication device is terminal device 1, and the second communication device can be a network device or terminal device 2. The sensing scenario is a dual-base sensing scenario. The sensing method provided in this application embodiment includes:
[0254] S601 to S606 can be understood by referring to S501 to S506 above.
[0255] The first information in S507 above can be sent to the second communication device based on reporting conditions. There can be a variety of reporting conditions, and several are listed below through S607a to S607c.
[0256] S607a. The second communication device sends a first request to the first communication device. Correspondingly, the first communication device receives the first request.
[0257] The first request is used to request the first piece of information.
[0258] S607b. If the first communication device determines that the sensing demand has changed or the amount of change in the sensing result meets the first threshold, then execute S608.
[0259] The change in the sensing result that meets the first threshold is usually caused by changes in the sensing environment, such as the need for a larger speed measurement range.
[0260] S607c. If the first communication device determines that the reporting requirements of the second communication device are met, then S608 is executed.
[0261] The reporting requirement may include periodic, semi-continuous, or aperiodic reporting of the first information. Among them, the aperiodic reporting requires the second communication device to activate the reporting function of the first communication device when needed.
[0262] S608 to S612 can be understood by referring to S507 to S511, and will not be repeated here.
[0263] From the above Figure 6 As can be seen from the process described, the first communication device only sends the first information to the second communication device when the reporting conditions are met, which can reduce the waste of resources caused by frequently sending the first information.
[0264] like Figure 7 As shown, the first communication device is terminal device 1, and the second communication device can be a network device or terminal device 2. The sensing scenario is a dual-base sensing scenario. The sensing method provided in this application embodiment includes:
[0265] S701 to S707c can be understood by referring to S601 to S607c above.
[0266] S708. The first communication device sends first information to the second communication device, the first information indicating a set of suggested values, the set of suggested values including at least one set of reference information. Correspondingly, the second communication device receives the first information.
[0267] The set of suggested values can include multiple suggested values for each perception indicator. For example, SNR can include adjustment information for multiple suggested values such as SNR1, SNR2, and SNR3. Similarly, other perception indicators can have multiple suggested adjustment information.
[0268] Of course, the set of suggested values can include multiple suggested values for each resource parameter, such as signal power, where the set of suggested values can include ΔP. ue1 ΔPue2 ΔP ue3 This includes multiple suggested adjustments. Similarly, other resource parameters can also have multiple suggested adjustments.
[0269] S709. The second communication device determines a second sensing resource based on at least one reference information in the set of suggested values.
[0270] S710a to S712 can be understood by referring to S610a to S612 above, and will not be repeated here.
[0271] From the above Figure 7 As described in the introduction, the set of suggested values can include multiple reference information, each including at least one reference information. For example, multiple suggested values can be provided for the second communication device to refer to for the same sensing index or resource parameter. This improves both the adaptability of the second sensing resources to sensing needs and the flexibility of the second communication device in determining the second sensing resources.
[0272] like Figure 8 As shown, the first communication device is a terminal device, and the second communication device can be a network device. This sensing scenario is a single-base sensing scenario. The sensing method provided in this application embodiment includes:
[0273] Should Figure 8 The process of the described embodiments and Figure 7 The process described is basically the same, the difference being that the sensing signal of the S804 is sent by the first communication device, not the second communication device. Other steps can be found in the previous sections. Figures 5 to 7 Understand the introduction of the basic scenarios.
[0274] The communication system and communication method in the embodiments of this application have been described above. The communication device provided in the embodiments of this application will be described below.

Optionally, the communication device further includes at least one memory 1212, at least one transceiver 1213, and one or more antennas 1215.
