Description

A communication method and related apparatus

[0001] This application claims priority to Chinese Patent Application No. 202510054208.X, filed on January 10, 2025, entitled "A Communication Method and Related Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, and in particular to a communication method and related apparatus. Background Technology

[0003] In recent years, wireless sensing technology has attracted widespread attention from the academic community. Wireless sensing technology analyzes the changes in wireless signals during propagation to obtain the characteristics of the signal propagation space (channel), thereby achieving scene perception. The main function of a wireless communication system is to facilitate information exchange between transceivers. Its basic principle is that the transmitter emits a specific waveform signal, which is received by the receiver after passing through the wireless channel, and then demodulated after signal processing. From the perspective of the entire physical process of transmission, reception, and transmission, radar and wireless communication are extremely similar. How to integrate wireless communication and sensing technologies (such as radar) to simultaneously achieve communication and environmental perception has become a current research hotspot.

[0004] In wireless sensing applications, distance resolution is a key technical indicator. Furthermore, distance resolution is related to signal bandwidth; the larger the bandwidth, the better the distance resolution performance. However, in existing wireless communication systems, each single frequency band often struggles to meet the requirements for sensing ranging resolution.

[0005] Therefore, how to aggregate multiple frequency bands to increase the effective bandwidth of sensing and thus improve resolution performance is a problem worth studying. Summary of the Invention

[0006] This application provides a communication method and related apparatus that can report the joint sensing measurement results of multi-frequency band measurement objects through a measurement report.

[0007] The first aspect of this application provides a communication method that can be applied to a terminal side, such as a terminal or a device within the terminal (e.g., a module, communication module, circuit or chip responsible for communication and / or sensing functions (e.g., a modem chip, also known as a baseband chip, or a system-on-chip (SoC) chip or system-in-package (SIP) chip containing a modem core), a chip system, or a processor), or it can be a logical node, logical module, or software capable of implementing all or part of the functions of a terminal or access network device. In the first aspect and its possible implementations, the method is described as being executed by a terminal device. In this method, the terminal device receives first information indicating an event identifier associated with multiple measurement objects, at least two of which use different frequency bands, and the event identifier is associated with the multiple measurement objects. The terminal device sends a measurement report, which includes multiple sensing measurement results, each of which is associated with multiple measurement objects.

[0008] Each sensing measurement result can also be understood as the result of joint sensing by multiple measurement objects. An event, also called a measurement event, is used by the terminal device to determine whether to send a measurement report, or can be understood as an event that triggers the terminal device to report a measurement report.

[0009] Based on the above scheme, the terminal device determines an event identifier and multiple measurement objects through first information. The event identifier is associated with multiple measurement objects, and at least two of the measurement objects use different frequency bands. After determining the event identifier and multiple measurement objects, the terminal device sends a measurement report. This report includes multiple sensing measurement results, and each of these results is associated with multiple measurement objects. On the one hand, multi-band sensing is beneficial for improving sensing performance. On the other hand, since each of the multiple sensing measurement results is associated with multiple measurement objects, any single sensing measurement result can characterize the measurement result of the joint sensing of multiple measurement objects.

[0010] The second aspect of this application provides a communication method, which is executed by a network device, or by a component of the network device (e.g., a processor, circuit, chip, or chip system), or by a logic module or software capable of implementing all or part of the functions of the network device, or by a combination of software and hardware. In this second aspect and its possible implementations, the method is described as being executed by a network device. In this method, the network device sends first information, which indicates an event identifier associated with multiple measurement objects, at least two of which use different frequency bands, and the event identifier is associated with the multiple measurement objects. After sending the first information, the network device receives a measurement report, which includes multiple sensing measurement results, each of which is associated with multiple measurement objects.

[0011] Each sensing measurement result can also be understood as the result of joint sensing by multiple measurement objects. An event, also called a measurement event, is used by the terminal device to determine whether to send a measurement report, or can be understood as an event that triggers the terminal device to report a measurement report.

[0012] Based on the above scheme, the network device sends first information to enable the terminal device to determine that the event identifier is associated with multiple measurement objects, and that at least two of the measurement objects use different frequency bands. After determining the event identifier and multiple measurement objects, the terminal device sends a measurement report, which includes multiple sensing measurement results, and each of the multiple sensing measurement results is associated with multiple measurement objects. On the one hand, multi-band sensing is beneficial to improving sensing performance. On the other hand, since each of the multiple sensing measurement results is associated with multiple measurement objects, any sensing measurement result can characterize the measurement result of joint sensing of multiple measurement objects.

[0017] In this possible implementation, not only can joint sensing measurement results (such as intensity and / or phase) that affect whether coherent synthesis is possible be transmitted, but also sensing measurement results that indicate whether the new measurement object improves multipath resolution and / or multipath sidelobe level can be transmitted.

As shown in Figure 1, the communication system includes a radio access network (RAN) 100 and a core network 200. Optionally, the communication system 1000 may also include an Internet 300. The RAN 100 includes at least one RAN node (110a and 110b in Figure 1, collectively referred to as 110), and may also include at least one terminal device (120a-120j in Figure 1, collectively referred to as 120). The RAN 100 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in Figure 1). The terminal device 120 is wirelessly connected to the RAN node 110, and the RAN node 110 is wirelessly or wiredly connected to the core network 200. The core network device in the core network 200 and the RAN node 110 in the RAN 100 can be independent and different physical devices, or they can be the same physical device integrating the logical functions of the core network device and the logical functions of the RAN node. Terminal devices and RAN nodes can be interconnected via wired or wireless means.

[0112] RAN100 can be an evolved universal terrestrial radio access (E-UTRA) system, an NR system, or a future radio access system as defined in 3GPP. RAN100 can also include two or more of the above-mentioned different radio access systems. RAN100 can also be an open RAN (O-RAN).

[0113] RAN nodes, also known as radio access network devices, RAN entities, or access nodes, are used to help terminal devices access communication systems wirelessly. Furthermore, RAN nodes can also be called network devices, which are apparatuses deployed in a radio access network to provide wireless communication and / or sensing functions for terminal devices. Network devices can include various forms of macro base stations, micro base stations (also known as small cells), relay stations, access points, etc. The names of network devices may differ in systems employing different radio access technologies. It is understood that all or part of the functions of the access network devices in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (e.g., a cloud platform). The embodiments of this application do not limit the specific technologies or specific device forms used in the radio access network devices.

[0114] In one application scenario, a RAN node can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation NodeB (gNB) in a 5G mobile communication system, or a base station in a future mobile communication system. A RAN node can be a macro base station (as shown in Figure 1, 110a), a micro base station or an indoor station (as shown in Figure 1, 110b), a relay node or a donor node, or a radio controller in a Cloud Radio Access Network (CRAN) scenario. Of course, in future communication systems, RAN nodes may also be wearable devices or vehicle-mounted devices, etc.

[0115] In another application scenario, multiple RAN nodes can collaborate to help terminal devices achieve wireless access, with different RAN nodes implementing different functions of the base station. For example, as shown in Figure 2, the RAN node can be a CU, DU, or radio unit (RU). Here, the CU performs the functions of the base station's Radio Resource Control (RRC) and Packet Data Convergence Protocol (PDCP), and can also perform the functions of the Service Data Adaptation Protocol (SDAP). The DU performs the functions of the base station's Radio Link Control (RLC) and MAC layers, and can also perform some or all of the physical layer (PHY) functions (e.g., high-PHY, H-PHY). For specific descriptions of these protocol layers, refer to the relevant 3GPP technical specifications. The RU can be used to implement radio frequency signal transmission and reception functions or some physical layer functions (e.g., low-PHY, L-PHY). The CU and DU can be two independent RAN nodes, or they can be integrated into the same RAN node, for example, integrated into the baseband unit (BBU). RUs can be included in radio frequency equipment, such as remote radio units (RRUs) or active antenna units (AAUs). CUs can be further divided into two types of RAN nodes: CU-control plane (CP) and CU-user plane (UP).

[0116] In different systems, RAN nodes may have different names. For example, in an O-RAN system, a CU can be called an open CU (O-CU), a DU can be called an open DU (O-DU), and an RU can be called an open RU (O-RU). The RAN nodes in the embodiments of this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules. For example, a RAN node can be a server loaded with the corresponding software modules. The embodiments of this application do not limit the specific technology or device form used in the RAN nodes.

[0117] A terminal device is a device with wireless transceiver capabilities, capable of sending signals to or receiving signals from RAN nodes. Terminal devices can also be called user equipment (UE), mobile stations, mobile terminal devices, etc. They can be widely used in various scenarios, such as wireless fidelity (WiFi) systems, device-to-device (D2D) communication, vehicle-to-everything (V2X) communication, machine-type communication (MTC), the Internet of Things (IoT), virtual reality (VR), augmented reality (AR), industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, intelligent transportation, and smart cities. Terminal devices can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, vehicles, airplanes, ships, robots, robotic arms, smart home devices, etc. The embodiments of this application do not limit the specific technologies or device forms used in the terminal devices.

[0118] For example, a terminal device is a wearable device. 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 just 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 only one type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets, smart helmets, and smart jewelry.

[0119] For ease of description, the communication system illustrated in Figure 1 is described using a base station as an example of an access network device. It is understood that when the communication system includes an IAB network, the base station can be an IAB node. It should be noted that in the embodiments of this application, the base station and the access network device can be interchanged.

[0120] Base stations and terminal equipment can be fixed or mobile. They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can be deployed on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of the base stations and terminal equipment.

[0121] The roles of base stations and terminal devices can be relative. For example, the helicopter or drone 120i in Figure 1 can be configured as a mobile base station. For terminal devices 120j that access the wireless access network 100 through 120i, terminal device 120i is a base station; however, for base station 110a, 120i is a terminal device, meaning that 110a and 120i communicate via a wireless air interface protocol. Of course, 110a and 120i can also communicate via a base station-to-base station interface protocol. In this case, relative to 110a, 120i is also a base station. Therefore, both base stations and terminal devices can be collectively referred to as communication devices. 110a and 110b in Figure 1 can be called communication devices with base station functions, and 120a-120j in Figure 1 can be called communication devices with terminal device functions.

[0122] Communication between base stations and terminal devices, between base stations, and between terminal devices can be conducted using licensed spectrum, unlicensed spectrum, or both simultaneously. Communication can be conducted using spectrum below 6 GHz, spectrum above 6 GHz, or both simultaneously. The embodiments of this application do not limit the spectrum resources used for wireless communication.

[0123] In the embodiments of this application, the functions of the base station can be executed by modules (such as chips) within the base station, or by a control subsystem that includes base station functions. This control subsystem, including base station functions, can be a control center in the aforementioned application scenarios such as smart grids, industrial control, intelligent transportation, and smart cities. Similarly, the functions of the terminal device can be executed by modules (such as chips or modems) within the terminal device, or by a device that includes terminal device functions.

[0124] In this application, the base station sends downlink signals or downlink information to the terminal, with the downlink information carried on the downlink channel; the terminal sends uplink signals or uplink information to the base station, with the uplink information carried on the uplink channel. In order to communicate with the base station, the terminal needs to establish a radio connection on a cell controlled by the base station. The cell with which the terminal has established a radio connection is called the terminal's serving cell.

[0125] As can be understood, RAN100, as previously described, includes at least one RAN node (110a and 110b in Figure 1, collectively referred to as 110), and may also include at least one terminal device (120a-120j in Figure 1, collectively referred to as 120).

[0126] In one possible implementation, the communication system includes a RAN node 110 and multiple terminal devices. In this case, a single RAN node can transmit data or control signaling to one or more terminal devices.

[0127] In another possible implementation, the communication system includes multiple RAN nodes 110 and a terminal device 120. In this case, the multiple RAN nodes can also transmit data or control signaling to a single terminal device simultaneously.

[0128] Please refer to Figure 3, which is another architectural diagram of the communication system used in the embodiments of this application. This communication system can also be referred to as an O-RAN intelligent management platform or a service management and orchestration (SMO) framework, etc. Specifically, the communication system includes: an open cloud infrastructure platform O-Cloud (the O-RAN operating platform), O-RAN network functions, an O-RAN intelligent management platform, a 5G core network, and external systems, etc.

[0129] O-Cloud is a cloud computing platform that includes: physical infrastructure nodes that meet O-RAN requirements (such as general-purpose computers or dedicated hardware platforms), cloud platform software, and O-RAN-related management and orchestration functions.

[0130] The network functions of O-RAN are the core of O-RAN. The main body and core functions of O-RAN are implemented through these network functions. O-RAN network functions can be understood as an extension based on existing 5G-RAN functions. O-RAN network functions include one or more of the following: Real-time RAN Intelligent Controller (RT RIC), O-RAN Central Unit-Control Plane (O-CU-CP), O-RAN Central Unit-User Plane (O-CU-UP), O-RAN Distributed Unit (O-DU), and O-RAN Radio Unit (O-RU).

[0131] For example, the measurement reports and measurement events involved in the embodiments of this application are configured through RRC, which may affect the functions of O-CU-CP network elements in O-RAN.

[0132] Specifically, as shown in Figure 2 above, the CU carries the logical nodes for the RRC and PDCP protocol control plane portions. The O-CU-UP carries the logical nodes for the RLC / MAC / high-PHY layers, based on the lower-layer function splitting. The O-RU carries the logical nodes for the low-PHY layer and radio frequency processing based on the lower-layer function splitting. This is similar to 3GPP's "TRP" or "remote radio head (RRH)," but includes the low-PHY layer (e.g., fast fourier transform (FFT) / inverse fast fourier transform (iFFT), physical random access channel (PRACH), etc.).

[0133] O-RAN Intelligent Management Platform: The SMO functions similarly to the traditional closed RAN access network equipment's network operation and maintenance subsystem, such as the operation and maintenance (OAM) system, network management system (NMS), or network management system.

[0134] The 5G core network can handle mobile terminal connection, billing, mobility management, mutual communication, and communication with external devices (such as the Internet and fixed telephone networks), etc., without being limited here.

[0135] External systems can leverage the various O-RAN management and orchestration services provided by the SMO to design, write, manage, and operate a variety of applications for 5G systems. Simultaneously, they can provide the SMO with rich historical data as a reference for intelligent management and operation of 5G systems, helping the SMO to provide more intelligent management and operational services.

[0136] In addition, the architecture shown in Figure 3 includes one or more of the following interfaces: NG interface, O1 interface (i.e., Open 1 interface), O2 interface (i.e., Open 2 interface), open fronthaul M-plane interface, or A1 interface, etc.

[0137] Specifically, the NG interface: Core Network - Control Plane and Data Plane Interface, is the standard interface between the 5G access network and the 5G core network.

[0138] O1 Interface: Radio Access Network - Resource Management Interface. This is a new interface between the SMO and the internal network elements of the O-RAN, used by the SMO for intelligent management and operation of logical network elements within the O-RAN, such as O-CU-CP, O-CU-UP, O-DU, and O-RU. CU-CP, CU-UP, DU, and RU are all logical network elements of the 5G system.

[0139] O2 Interface: The "cloud" resource management interface is a new interface between SMO and O-Cloud, used by SMO to intelligently manage and operate various O-RAN network service nodes running on the O-Cloud cloud platform.

[0140] Open fronthaul management-plane (FH M plane): also known as open fronthaul m-plane interface, mainly the RU-resource management interface. In the 5G system specification, the fronthaul m-plane refers to the internal management interface between DU and RU.

[0141] A1 Interface: Radio Access Network - Non-real-time Control and Optimization Interface. Used by the SMO for intelligent and dynamic fine-grained control of radio resources within the 0-RAN.

[0142] The overall framework of the O-RAN provided in this application embodiment has been described above with reference to Figure 3. The architecture of the internal logical network elements of the O-RAN is described below.

[0143] Please refer to Figure 4, which is a schematic diagram of another architecture of the communication system used in the embodiments of this application. This communication system may also be referred to as an SMO framework, etc. Specifically, the communication system includes one or more of the following: NRT RIC, 4G LTE network element eNB, or 5G NR network element, etc.

[0144] NRT RIC can be understood as O-RAN network function (NF) that includes the Near-RT RIC platform and Near-RT RIC applications (xApps).

[0145] 4G LTE eNB: For a long time, 5G will not be a standalone (SA) network, but a hybrid 4G+5G network (non-standalone, NSA). Therefore, O-RAN cannot exclude 4G LTE eNB. However, considering that LTE is already a mature and deployed network, O-RAN did not further divide the LTE eNB, but extended it as a whole radio resource: 1) O1 interface, used for intelligent configuration and management of O-eNB; 2) E2 interface, used for controlling the radio resources of O-eNB.

[0146] 5G NR network elements: These are all standard network elements defined by the 5G system, such as CU-CP, CP-UP, DU, RU, etc. O-RAN has made open extensions to these standard network elements to support intelligent management of them through SMO: O-RU, O-DU, O-CU-CP, O-CP-UP (Open-Centralized Unit-Data Plane).

[0147] O1 interface: Used for intelligent configuration and management of O-RAN internal network elements.

[0148] E2 interface: Used to control the radio resources of O-RAN internal network elements.

[0149] The Open (Fronthaul, FH) control user synchronization (CUS) Plane (i.e., Open-FH CUS-Plane) is used for clock synchronization between the DU and RU.

[0150] Open FH M-Plane: Used for DU to manage RU configuration.

[0151] Please refer to Figure 5, which is a schematic diagram of another architecture of the communication system used in the embodiments of this application. The communication system includes one or more of the following: network exposure function (NEF) entity, unified data repository (UDR) entity, unified data management (UDM) entity, application function (AF), network data analytics function (NWDAF) entity, access and mobility management function (AMF) entity, sensing function (SF), gateway sensing center (GSC) entity, sensing service client, access network equipment, terminal or sensing reference unit (SRU), etc.

[0152] The NEF entity, also known as a NEF network element or NEF functional entity, can reside between the core network and third-party application (or external application) functional entities. Third-party applications need to access data within the core network through the NEF entity. The NEF entity can securely expose interfaces to third-party applications, thereby ensuring the security of third-party applications accessing the 3GPP network. The NEF entity can also be responsible for functions such as enabling third-party application quality of service (QoS) customization, mobility state event subscription, and AF request distribution.

[0153] A UDR entity can also be called a UDR network element or a UDR functional entity. A UDR entity can be used to store terminal data, such as the terminal's subscription data.

[0154] UDM entities can also be called UDM network elements or UDM functional entities. UDM entities can be used to manage and store terminal data, such as managing terminal subscription data.

[0155] Application layer (AF) can refer to various services. AF can be an internal operator application, such as a Voice over LTE (VoLTE) AF (e.g., a 4G VoLTE application server (AS)); or, AF can be a third-party AF, such as a video server or a game server.

[0156] The NWDAF entity can also be called an NWDAF network element or an NWDAF functional entity. The NWDAF entity is responsible for analyzing network data and using the analysis results for network function optimization and decision-making.

[0157] The AMF entity is responsible for managing registration, connection, reachability, and mobility; providing a transmission channel for session management messages between terminals and SMF entities; providing authentication and authorization functions for user access; and serving as an access point for terminals and the core network control plane.

[0158] SF (Sensing Element) can be used for sensing management. SF can be located in terminal devices, access network devices, or the core network; alternatively, SF can be a network element independent of the terminal or access network device. SF can also have other names, such as sensing management network element, sensing management device, sensing management entity, sensing management function, ISAC management function (ISACMF), ISAC service management function (ISACSMF), or sensing service management function (SSMF), etc., without specific limitations here. For example, if the SF is located within a terminal device, the terminal device can sense the sensing target through the SF. Similarly, if the SF is located within an access network device, the access network device can sense the sensing target through the SF. Several possible scenarios of terminal device sensing and access network device sensing will be described later with reference to Figure 6, and will not be elaborated upon here.

[0159] GSC can receive sensing requests from sensing service clients and send information about the sensing target (or the sensing information of the target) to the sensing service clients.

[0160] The sensing service client can be a logical functional entity. It can be an entity within a public land mobile network (PLMN), such as an operation and management (O&M) tool; or it can be an entity outside the PLMN, such as a third-party location server deployed by a non-operator. The sensing service client initiates a sensing request carrying parameters such as QoS to obtain the location information of one or more sensing targets.

[0161] The SRU can be located at a known location to perform sensing measurements (e.g., measuring one or more of the reference signal time difference (RSTD), RSRP, or UE Rx-Tx Time Difference) and report the measurement results to the sensing server. Additionally, the SRU can transmit a sensing reference signal, enabling access network devices to measure the sensing reference signal transmitted from the SRU located at a fixed location and report uplink sensing measurement results (one or more of the relative time of arrival (RTOA), uplink angle of arrival (UL-AOA), or gNB Rx-Tx Time Difference). The sensing server can compare the SRU's measurement results with the expected measurement results at the SRU's location to derive correction terms for other objects near the SRU. The downlink and / or uplink sensing measurement results of these other objects can be corrected according to these correction terms. From the sensing server's perspective, the SRU can be considered a terminal with a known location.

[0162] The communication systems and service scenarios described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new service scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0163] It is understood that Figures 1 to 5 above are only several structural framework diagrams of the communication system that may be involved in the embodiments of this application. In other embodiments, there may be other structural frameworks, which are not limited here.

[0164] With the development of communication technology, future communication systems may provide sensing services in addition to communication services. This type of network can be understood as an ISAC network. As an example, taking access network devices and / or terminal devices as sensing devices, sensing signals may be transmitted between access network devices and terminal devices, between terminal devices, and between access network devices. The following describes several scenarios with reference to Figure 6, using a vehicle as the target object.

[0165] As shown in Figure 6, the sensing signal can have the following seven scenarios:

[0166] Scenario 1: The access network device (e.g., BS) acts as the transmitter and controller, and the terminal device (e.g., UE) acts as the receiver. The signal transmitted by the access network device passes through the target object and is received by the terminal device. After receiving the signal, the terminal device performs signal processing at the processing node to obtain the perception result.

[0167] Scenario 2: The terminal device acts as the transmitter, and the access network device acts as the receiver and control end. The signal transmitted by the terminal device is received by the access network device after passing through the target object. After receiving the signal, the access network device performs signal processing at the processing node to obtain the sensing result.

[0168] Scenario 3: Access network device #1 acts as the transmitter and control end, and access network device #2 acts as the receiver. The signal transmitted by access network device #1 is received by access network device #2 after passing through the target object. After receiving the signal, access network device #2 performs signal processing at the processing node to obtain the sensing result.

[0169] Scenario 4: Terminal device #1 acts as the transmitter and control end, and terminal device #2 acts as the receiver. The signal transmitted by terminal device #1 is received by terminal device #2 after passing through the target object. After receiving the signal, terminal device #2 performs signal processing at the processing node to obtain the perception result.

[0170] Scenario 5: Access network device #1 acts as the transmitter, access network device #2 acts as the receiver, and access network device #3 acts as the control terminal. The signal transmitted by access network device #1 is received by access network device #2 after passing through the target object. After receiving the signal, access network device #2 performs signal processing at the processing node to obtain the sensing result.

[0171] Scenario 6: The access network device acts as the transmitter, receiver, and control unit. The signal transmitted by the access network device passes through the target object and is received by the access network device. After receiving the signal, the access network device performs signal processing at the processing node to obtain the sensing results, which include information such as distance, speed, angle, and intensity.

[0172] Scenario 7: The terminal device acts as the transmitter, receiver, and control unit. The signal transmitted by the terminal device passes through the target object and is received by the terminal device. After receiving the signal, the terminal device processes the signal at the processing node to obtain the perception result.

[0173] The target objects in the above scenarios may include one or more of the following: vehicles, pedestrians, bicycles, or drones, etc., without specific limitations here. The "effect" of the transmitted signal in the above scenarios may include one or more of the following: reflection, diffraction, or scattering, etc., without specific limitations here. The perception results in the above scenarios may include one or more of the following: the distance to the target object, the speed of the target object, the angle related to the target object (e.g., the angle of arrival or departure of the transmitted signal), or the strength of the received signal, etc.

[0174] Optionally, the target objects in each scenario shown in Figure 6 can be active or passive objects; this is not limited here. Furthermore, the number of access network devices, terminal devices, and target objects in each scenario in Figure 6 can be one or more; this is not specifically limited here. The control terminal can also possess sensing capabilities. Alternatively, the control node can be a core network device, such as an access and mobility function (AMF), or it can be a location management function (LMF), sensing management function (SMF), location server (LS), distribution system (DS), etc.

[0175] In this embodiment of the application, the terminal device may be the terminal device shown in Figures 1 to 6 above, and the network device may be the RAN node or core network shown in Figures 1 to 6 above.

[0176] Secondly, some terms used in the embodiments of this application will be explained to facilitate understanding by those skilled in the art.

[0177] 1. Configuration and Pre-configuration: This application uses both configuration and pre-configuration. Configuration refers to the network device / server sending configuration information or parameter values ​​to the terminal via messages or signaling, so that the terminal can determine communication parameters or transmission resources based on these values ​​or information. Pre-configuration is similar to configuration; it can be parameter information or parameter values ​​pre-negotiated between the network device / server and the terminal device, parameter information or parameter values ​​specified by standard protocols for use by the base station / network device or terminal device, or parameter information or parameter values ​​pre-stored in the base station / server or terminal device. This application does not limit this.

[0178] Furthermore, these values ​​and parameters can be changed or updated.

[0179] 2. In this application, "for indicating" can include both direct and indirect indication. When describing an indication information as indicating A, it can be understood that the indication information carries A, directly indicates A, or indirectly indicates A.

[0180] In this application, the information indicated by the instruction information is called the information to be instructed. In specific implementation, there are many ways to instruct the information to be instructed. For example, it can be implemented through direct instruction, such as through the information to be instructed itself or its index. It can also be implemented indirectly by instructing other information, where there is a relationship between the other information and the information to be instructed. Alternatively, only a part of the information to be instructed can be indicated, while the other parts are known or pre-agreed upon. For example, the instruction of specific information can be achieved by using a pre-agreed (e.g., protocol-defined) arrangement of various pieces of information, thereby reducing instruction overhead to some extent.

[0181] The information to be instructed can be sent as a whole or divided into multiple sub-information messages, and the sending period and / or timing of these sub-information messages can be the same or different. This application does not limit the specific sending method. The sending period and / or timing of these sub-information messages can be predefined, for example, according to a protocol, or configured by the transmitting device by sending configuration information to the receiving device. This configuration information can include, for example, but not limited to, one or a combination of at least two of radio resource control (RRC) signaling, medium access control (MAC) layer signaling, and physical layer signaling. MAC layer signaling includes, for example, MAC layer control elements (CE); physical layer signaling includes, for example, downlink control information (DCI), uplink control information (UCI), sidelink control information (SCI), etc.

[0182] 3. In the embodiments of this application, "sending" and "receiving" indicate the direction of signal transmission. In this application, entity A sends information to entity B, either directly to B or indirectly through other entities. Similarly, entity B receives information from entity A, either directly or indirectly through other entities. Entities A and B can be radio access network (RAN) nodes or terminals, or modules within RAN nodes or terminals. Information sending and receiving can be information interaction between RAN nodes and terminals, such as information interaction between a base station and a terminal; information sending and receiving can also be information interaction between two RAN nodes, such as information interaction between a central unit (CU) and a distributed unit (DU); information sending and receiving can also be information interaction between different modules within a device, such as information interaction between a terminal chip and other modules of the terminal, or information interaction between a base station chip and other modules of the base station. "Sending" can also be understood as the "output" of the chip interface, such as the baseband chip outputting information to the radio frequency chip, and "receiving" can also be understood as the "input" of the chip interface; for example, "sending" can also be understood as the baseband part inside the device outputting information to the radio frequency part, and "receiving" can also be understood as the radio frequency part inside the device receiving the information output by the baseband part.

[0183] 4. The terms "system" and "network" in the embodiments of this application can be used interchangeably. "At least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, or B exists 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.

[0184] 5. Integrated Sensing and Communication (ISAC)

[0185] Communication and sensing integration can also be simply referred to as communication and sensing integration or communication and sensing. ISAC can be simply understood as the fusion of communication and sensing.

[0186] Among them, integrated communication and sensing technology will utilize wireless communication signals to achieve sensing functions such as target detection, positioning, identification, and imaging, thereby acquiring and reconstructing surrounding environmental information and propelling future communication networks into a digital twin era that merges the physical and digital worlds. The International Telecommunication Union (ITU) report on future technology trends points out that integrated communication and sensing technology will become one of the most promising key technology directions for next-generation mobile communication systems.

[0187] 6. Perception

[0188] Wireless sensing, also known as electromagnetic sensing, refers to the process of emitting electromagnetic energy into space and then calculating information about objects by receiving the reflected electromagnetic waves. This includes parameters such as position, direction, height, speed, size, and trajectory, as well as detecting the internal and external shape and structure of objects. By exploring the transmission, echo, reflection, and scattering of radio waves, we can perceive and better understand the physical world. As an electromagnetic wave sensing technology, wireless sensing technology, due to its penetrability and security, can serve as an important alternative technology for security inspections, concealed object detection, environmental reconstruction, and other applications.

[0189] Sensing can be further categorized into several types: single-base sensing, dual-base sensing, and multi-base sensing. Single-base sensing can also be called monostation sensing, dual-base sensing can also be called bistation sensing, and multi-base sensing can also be called multistation sensing.

[0190] Single-site sensing refers to a system where the transmitting device for the sensing signal and the receiving device for the echo signal are the same device. In other words, in single-site sensing, the transmitting device must both transmit the sensing signal and receive the echo signal reflected from the surface of the sensing target. Therefore, this single-site sensing can also be called a self-transmitting and self-receiving mode, without any restrictions.

[0191] Dual-station sensing refers to a system where the transmitting device for the sensing signal and the receiving device for the echo signal are two different devices. In other words, sensing station A transmits a sensing signal, and the echo signal reflected from the surface of the sensing target is received by sensing station B. Therefore, this dual-station sensing can also be called the A-transmit, B-receive mode. It should be noted that the echo signal is obtained after the sensing signal has passed through the sensing target (e.g., reflection, diffraction, or scattering), therefore, this echo signal can still be called the sensing signal.

[0192] Multi-station sensing refers to the joint operation of multiple devices in transmitting and receiving sensing signals. Specifically, multi-station sensing can be further divided into single-transmitter-multiple-receiver, multiple-transmitter-single-receiver, and multiple-transmitter-multiple-receiver scenarios. For example, in one possible scenario, sensing station A transmits a sensing signal, which, after passing through a sensing target, generates an echo signal, which is received by sensing stations B1 and B2. In another possible scenario, sensing stations A1 and A2 transmit sensing signals simultaneously or sequentially, which, after passing through a target, generate an echo signal, which is received by sensing station B. Yet another possible scenario, sensing stations A1 and A2 transmit sensing signals simultaneously or sequentially, which, after passing through a target, generate an echo signal, which is received by sensing stations B1 and B2. A special case is where multi-station sensing is achieved through multiple single-station sensing operations. For example, in a system, sensing station A performs single-station sensing, and sensing station B also performs single-station sensing; the final sensing results are then fused. Multi-station sensing can take many forms, and this application does not limit it.

[0193] The perception scenario involved in this application can be as shown in Figure 6 above, and will not be described in detail here.

[0194] 7. Terminology related to carrier aggregation (CA)

[0195] Carrier aggregation (CA) combines multiple consecutive or non-consecutive component carriers (CCs) into a larger bandwidth. Terminal devices can then transmit through this bandwidth, thereby increasing the overall transmission bandwidth.

[0196] The primary cell (PCell) is the cell where terminal devices supporting CA (e.g., CA UEs) reside. The operation of a CA UE within this primary cell is no different from that in a single-carrier cell.

[0197] A secondary cell (SCell) is a cell configured by network equipment (such as a base station) for a CA UE via RRC connection signaling, which can provide the CA UE with more radio resources. A SCell can have only downlink or both uplink and downlink.

[0198] The primary component carrier (PCC) refers to the CC corresponding to the PCell.

[0199] Secondary component carrier (SCC) refers to the CC corresponding to the SCell.

[0200] For example, in the embodiments of this application, PCC can be equivalent to the primary frequency layer (PFL) or the positioning frequency layer (PFL), and correspondingly, SCC can be equivalent to the secondary frequency layer (SFL) or the sensing frequency layer (SFL). As another example, in the embodiments of this application, PCC can be equivalent to PCell, and correspondingly, SCC can be equivalent to SCell. As yet another example, in the embodiments of this application, PCC can be equivalent to PCell, and correspondingly, SCC can be equivalent to SCell. As yet another example, in the embodiments of this application, PCC can be equivalent to the primary bandwidth part (PBWP), and correspondingly, SCC can be equivalent to the secondary bandwidth part (SBWP).

[0201] 8. Event

[0202] The events in this application embodiment can also be called measurement events. Events are used by the terminal device to determine whether to send a measurement report, or can be understood as events used to trigger the terminal device to report a measurement report.

[0203] In this application's embodiments, the concept of "identity (ID)" is generic. Specifically, an identifier can be described as an indicator, index, number, or sequence number, etc., without limitation here. Alternatively, it can be understood that the identifier, indicator, index, number, and sequence number in this application's embodiments can be interchanged or interpreted interchangeably. Correspondingly, an event identifier can also be called an event indicator, event index, event number, or event sequence number, etc.

[0204] 9. Measurement object

[0205] The measurement object in this embodiment can also be equivalent to a cell. The frequency domain resources used by the measurement object include one or more of the following: CC, frequency layer (FL), or bandwidth part (BWP). Alternatively, it can be understood that the frequency attributes of the measurement object include one or more of the following: CC, FL, or BWP, etc., without specific limitations here. For ease of description, the following example uses two measurement objects using two different frequency domain resources, frequency domain resource 1 and frequency domain resource 2, respectively. Alternatively, it can be understood that the two measurement objects are two cells (e.g., cell 1 and cell 2), with cell 1 using frequency domain resource 1 and cell 2 using frequency domain resource 2.

[0206] FL can indicate a set of frequency resources, used to indicate one or more frequency resources.

[0207] For example, in a sensing scenario, a certain measurement object might be responsible for distributing communication data across different measurement objects, or a certain measurement object might be responsible for sending control signaling and reporting sensing measurement results. Therefore, measurement objects may also be divided into primary measurement objects and secondary measurement objects. That is, the first measurement object can also be called the primary measurement object, and the second measurement object can also be called the secondary measurement object. Alternatively, the first measurement object can be called the secondary measurement object, and the second measurement object can be called the primary measurement object.

[0208] For example, the primary measurement object is called PCell, and the secondary measurement object is called SCell. Another example is that the frequency resource used by the primary measurement object is called PCC, and the frequency resource used by the secondary measurement object is called SCC. Yet another example is that the frequency resource used by the primary measurement object is called PFL, and the frequency resource used by the secondary measurement object is called SFL. Yet another example is that the frequency resource used by the primary measurement object is called PBWP, and the frequency resource used by the secondary measurement object is called SBWP. That is, multiple measurement objects may or may not have a primary and secondary concept; this is not limited here. Similarly, multiple frequency resources may or may not have a primary and secondary concept; this is not limited here. Optionally, multiple measurement objects may co-locate. Furthermore, multiple measurement objects may share an antenna or not.

[0209] Currently, CA-related measurement events (such as A2, A5, and A6 events) can only reflect the absolute performance of a single CC or cell, and cannot describe the joint performance of multiple CCs combined. Furthermore, the inventors discovered that multiple CCs differ in communication and sensing performance. Therefore, how to reflect the joint performance of multiple CCs in a CA scenario may be a future research direction.

[0210] The following examples, using two CCs and different frequency domain resources (e.g., CC1 corresponds to frequency domain resource 1, and CC2 corresponds to frequency domain resource 2; or, frequency resource 1 specifically refers to CC1, and frequency resource 2 specifically refers to CC2), illustrate the differences mentioned above through three examples.

[0211] 1. Whether resources in different frequency domains are coherent.

[0212] For example, as shown in Figure 7A, assume that the total bandwidth of frequency domain resource 1 + frequency domain resource 2 is fixed in both Method 1 and Method 2. In Method 1, frequency domain resource 1 and frequency domain resource 2 are incoherent and cannot be combined to form a large bandwidth to improve ranging resolution. In Method 2, frequency domain resource 1 and frequency domain resource 2 are coherent and can be coherently combined to form a large bandwidth, thus improving ranging resolution. That is, for communication, Method 1 and Method 2 have the same performance. However, for sensing, their performance differs, with Method 2 outperforming Method 1.

[0213] Among them, ranging resolution describes the ability to perceive two or more targets in the same direction but at different distances.

[0214] 2. Spacing between resources in different frequency domains.

[0215] For example, as shown in Figure 7B, assume that frequency domain resources 1 and 2 in both Method 1 and Method 2 are coherent, and the total bandwidth of frequency domain resources 1 + 2 is fixed. Frequency domain resources 1 and 2 in Method 1 are continuous in the frequency domain, while those in Method 2 are discontinuous, or in other words, there is a gap between them in the frequency domain. That is, for communication purposes, Method 1 and Method 2 have the same performance. However, for sensing purposes, their performance differs; Method 2 has better ranging resolution than Method 1, while Method 1 has better ranging sidelobe performance than Method 2.

[0216] 3. Frequency allocation between resources in different frequency domains.

[0217] For example, as shown in Figure 7C, assuming that frequency domain resources 1 and 2 in both Method 1 and Method 2 are coherent, the frequency spacing between them is fixed, and the total bandwidth of frequency domain resources 1 + 2 is fixed. In Method 1, the bandwidth of the two frequency domain resources 2 is greater than the bandwidth of frequency domain resource 1, while in Method 2, the bandwidth of frequency domain resource 1 is equal to the bandwidth of frequency domain resource 2. That is, for communication, Method 1 and Method 2 have the same performance. However, for sensing, their performances are different; Method 1 and Method 2 will differ in ranging resolution and ranging sidelobe performance, and the specific differences depend on the bandwidth allocation method.

[0218] It is understandable that Figures 7A-7C above are used to illustrate that different frequency domain resource characteristics (e.g., coherent or incoherent, continuous or discontinuous, frequency domain spacing) result in differences in communication and sensing performance.

[0219] In addition to discovering the differences in communication and sensing performance among the various frequency domain resources mentioned above, the inventors also discovered several factors that affect sensing performance.

[0220] For example, taking the SCell configuration with the corresponding measurement event A5 as an example, the A5 event is triggered by comparing the reference signal received power (RSRP), reference signal received quality (RSRQ), and signal-to-interference-plus-noise ratio (SINR) with a preset threshold. However, the impact on sensing performance cannot be characterized solely by the RSRP / RSRQ / SINR of the SCell. To better characterize the impact of adding the SCell on sensing performance, the following factors also need to be considered.

[0221] 1. Do the SCC and PCC share a site and / or an antenna? That is, are the SCC and PCC used to measure the same physical parameter (e.g., the distance to the target to be sensed)?

[0222] Since whether the SCC and PCC share a site and / or a antenna is irrelevant to the target being sensed, there is no need to determine this through measurement.

[0223] 2. Have the target characteristics observed by SCC and PCC changed? If the distance between SCC and PCC is too great, the electromagnetic characteristics of the target corresponding to the two may be different, resulting in inconsistent observed target characteristics.

[0224] Whether the target characteristics observed by SCC and PCC have changed depends on the specific target to be sensed and needs to be determined through measurement. Therefore, it is necessary to define the relevant measurement events separately.

[0225] 3. Whether SCC and PCC can be coherently combined directly determines whether the two CCs can improve the ranging resolution.

[0226] Whether SCC and PCC can be coherently combined depends on the specific transceiver and needs to be determined through measurement. Therefore, it is necessary to define the relevant measurement events separately.

[0227] It is understood that the above-mentioned factors affecting perception performance are just examples. In other embodiments, there may be other factors, which are not limited here.

[0228] In response to the factors that affect perception performance, taking multiple frequency domain resources, including frequency domain resource 1 and frequency domain resource 2, as an example, Figures 8A to 8C provide three typical scenarios.

[0229] As shown in Figure 8A, in Scenario 1, frequency domain resource 1 and frequency domain resource 2 are not co-located (i.e., Cell1 corresponds to frequency resource 1, and Cell2 corresponds to frequency resource 2). Frequency domain resource 1 and frequency domain resource 2 cannot be coherently combined into a large bandwidth. That is, they cannot be used to improve the resolution of sensing and ranging, nor can they be used to improve the signal-to-noise ratio (SNR) of sensing and ranging.

[0230] Scenario 2, as shown in Figure 8B, involves co-location and shared antenna between frequency domain resources 1 and 2, with no change in the observed target characteristics. However, frequency domain resources 1 and 2 are incoherent and cannot be combined into a large bandwidth. The inability to coherently combine frequency domain resources 1 and 2 into a large bandwidth means that the sensing and ranging resolution cannot be improved; however, frequency domain resources 1 and 2 can be used to improve the sensing and ranging SNR.

[0231] Scenario 3, as shown in Figure 8C, involves co-location and shared antenna between frequency domain resources 1 and 2. The observed target characteristics remain unchanged across both resources. Furthermore, frequency domain resources 1 and 2 are coherent, forming a large bandwidth that enhances sensing and ranging resolution.

[0232] Based on this, embodiments of this application provide a communication method in which a terminal device determines an event identifier associated with multiple measurement objects through first information. The event identifier is related to the multiple measurement objects, and at least two of the multiple measurement objects use different frequency bands. After determining the event identifier and the multiple measurement objects, the terminal device sends a measurement report. This measurement report includes multiple sensing measurement results, and each of the multiple sensing measurement results is related to the multiple measurement objects. On the one hand, multi-band sensing is beneficial for improving sensing performance. On the other hand, since each of the multiple sensing measurement results is related to the multiple measurement objects, any single sensing measurement result can characterize the measurement result of the joint sensing of multiple measurement objects.

[0233] Furthermore, the measurement results of joint sensing of multiple measurement objects may include one or more of the following: whether different measurement objects can be coherently synthesized, the difference in multipath resolution between other measurement objects and one or more of the multiple measurement objects, the difference in multipath sidelobe level, etc.

[0234] For example, whether different measurement objects can be coherently synthesized may involve several aspects: On the one hand, the characteristic differences of the same perceived target on different measurement objects (e.g., subsequent events S1 or S2). On the other hand, whether the sensing system or synesthetic system supports coherent synthesis (e.g., subsequent events S3 or S4). For example, the difference between the phase difference of the path of the perceived target on different measurement objects and the fitted straight line (which will be explained in conjunction with events later, and will not be elaborated here). Another example is whether synthesizing different measurement objects can improve ranging resolution, etc.

[0235] For example, when different measurement objects can be coherently combined, can the introduction of a new measurement object improve the multipath resolution of the original multiple measurement objects (e.g., subsequent event S5) or the multipath sidelobe level (e.g., subsequent event S6)?

[0236] The following sections will describe in detail the S1 to S6 mentioned above and the measurement results of joint sensing, with specific implementation examples. Here, we will only briefly describe the inventor's discovery, the general logic, and several factors considered in the measurement results of joint sensing.

[0237] The above describes several communication system architectures and conceptual frameworks provided in the embodiments of this application. The following is a detailed description of the communication methods provided in the embodiments of this application.

[0238] Please refer to Figure 9, a flowchart illustrating a communication method provided in this application embodiment. This method may include steps 901 and 902. Steps 901 and 902 can be executed by a communication device, or by some components of the communication device (e.g., processors, circuits, chips, or chip systems), or by a logic module or software capable of implementing all or part of the functions of the communication device. The following description uses the interaction between a terminal device and a network device as an example. The processing performed by a single execution entity in steps 901 and 902 can also be divided into multiple execution entities, which can be logically and / or physically separated. For example, when the communication device is an access network device, the processing performed by the communication device can be divided into at least one execution entity among network elements such as CU, DU, or RU. This method can be applied to any of the system architectures shown in Figures 1 to 6 above; specific limitations are not specified here.

[0239] Due to the long intervals between the steps, steps 901 and 902 will be briefly described here first, and then described in detail later. Step 901: The network device sends the first information to the terminal device. Step 902: The terminal device sends a measurement report to the network device.

[0240] Step 901: The network device sends the first information to the terminal device.

[0241] The first piece of information can also be called configuration information, enable information, or activation information. In other words, step 901 can also be understood as the process by which the network device configures, activates, or enables event identifiers and parameters such as multiple measurement objects for the terminal device.

[0242] For example, the first information can be called measurement configuration information or measConfig, etc., and the specific terminology is not limited here. For instance, step 601 can also be understood as the process by which the network device performs measurement configuration for the terminal device. For example, the first information can be provided through dedicated signaling, such as RRC Reconfiguration or RRC Resume.

[0243] For example, the first information can be called enabling information or activation information. Alternatively, it can be understood as: the network device has already configured / pre-configured various parameters for the terminal device before step 901. However, the terminal device needs to receive the first information before using the parameters. It can also be understood as: the parameters previously allocated to the terminal device by the network device were not activated, and the first information activates the parameters so that they can be used by the terminal device. It is understood that this example is merely illustrative; in other embodiments, the terminal device may directly use the parameters, etc., after receiving the first information, and this is not specifically limited here.

[0244] In this embodiment, the first information is used to indicate that an event identifier is associated with multiple measurement objects, at least two of which use different frequency bands. Furthermore, the event identifier is associated with multiple measurement objects.

[0245] Optionally, the first information may include one or more of the following parameters: measurement object (MO) parameters, reporting configuration (RC) parameters, or scenario identifiers (such as the multiple scenarios in Figure 6 above), etc., without specific limitations here. For example, the first information may include MO parameters. Or, the first information may include RC parameters. Or, the first information may include both MO and RC parameters. Where the MO and RC parameters each include multiple cases, the first information may also indicate the combination of MO and RC parameters through measurement identities. That is, the association between event identifiers and multiple measurement objects can be determined through measurement identities.

[0246] The MO and RC parameters that the first information may include are described below:

[0247] I. MO parameters.

[0248] Among them, the MO parameter includes the measurement object ID.

[0249] Optionally, the MO parameters may also include one or more of the following: carrier frequency, allowed measurement bandwidth, or subcarrier spacing (SCS). For example, the unit of carrier frequency can be Hertz (Hz), kilohertz (KHz), megahertz (MHz), etc., without specific limitations here. For example, the carrier frequency could be 1000MHz, 1500MHz, or 3500MHz. As another example, the unit of SCS can be KHz. For example, SCS could be any of the following: 15kHz, 30kHz, 60kHz, or 120kHz.

[0250] Furthermore, different measurement object identifiers correspond to one or more of the aforementioned parameters. The other parameters for different measurement objects may be the same or different.

[0251] In this application embodiment, there are several ways in which the first information indicates MO parameters. For example, the first information can directly indicate the identifiers of multiple measurement objects and other parameters corresponding to each measurement object identifier (such as one or more of the following: the corresponding carrier frequency, the allowed measurement bandwidth, or SCS). Another example is that if the terminal device is pre-configured with Table 1, the first information can implicitly indicate other parameters related to each measurement object identifier by indicating multiple measurement object identifiers.

[0252] For example, one example of Table 1 is as follows:

[0253] Table 1

[0254] Specifically, the carrier frequency corresponding to measurement object identifier 1 is 3500MHz, the allowable measurement bandwidth is 100MHz, and the SCS is 30kHz. The carrier frequency corresponding to measurement object identifier 2 is 3500MHz, the allowable measurement bandwidth is 100MHz, and the SCS is 15kHz. For example, taking the equivalent CC of the measurement object as an example, Table 1 shows other parameters related to measurement object identifier 1 and measurement object identifier 2.

[0255] It is understood that Table 1 is only one example of the object identification and other parameters. In other embodiments, there may be more or fewer other parameters than those in Table 1, which is not limited here.

[0256] II. RC parameters.

[0257] The RC parameters include the event ID, and different event configurations or associations have different parameter configurations.

[0258] Optionally, the RC parameters may also include one or more of the following: reporting configuration ID, reporting quantity, reference signal type, reporting format, reporting type, or at least one threshold corresponding to the event.

[0259] Furthermore, different event identifiers correspond to one or more of the parameters mentioned above. The other parameters corresponding to different reference event identifiers may be the same or different.

[0260] Similarly, there are several ways to indicate RC parameters in the first information. For example, the first information can directly indicate at least one event identifier and other parameters corresponding to each event identifier (such as one or more of the following: reporting configuration identifier, reporting quantity, reference signal type, reporting format, reporting type, one or more thresholds or reporting quantities corresponding to the event). Another example is if the terminal device is pre-configured with Table 2; in this case, the first information can implicitly indicate other parameters related to each event identifier simply by indicating at least one event identifier.

[0261] For example, taking events S1 and S2 as examples, one example of Table 2 is as follows:

[0262] Table 2

[0263] In this context, the threshold for event identifier S1 is the first threshold, the reference signal type is PRS, and the reported quantity is the intensity / intensity difference measured by the measured object. The threshold for event identifier S2 is the second threshold, the reference signal type is PRS, and the reported quantity is the phase / phase difference measured by the measured object.

[0264] It should be noted that the parameters in Table 2 are merely examples. For instance, one reporting configuration identifier can correspond to one or more events. Another example is that the reference signal type is a reference signal other than PRS. Yet another example is that the reported quantity is multipath resolution capability, multipath resolution capability difference, multipath sidelobe level, or multipath sidelobe level difference, etc. Events will be described in detail in conjunction with Tables 4 to 6 later; they will not be elaborated upon here.

[0265] It is understood that the other parameters corresponding to different event identifiers may be the same or different. Furthermore, Table 2 is merely an example of event identifiers and other parameters; in other embodiments, there may be more or fewer other parameters than those in Table 2, and this is not specifically limited here.

[0266] The following describes the parameters that may be included in the RC parameters:

[0267] 1. Report quantity.

[0268] The reported quantity may include one or more of the following: characteristics obtained from sensing measurements of the target object based on the measurement object; differences in characteristics obtained from sensing measurements of the same target object based on different measurement objects; whether different measurement objects can be coherently synthesized; phase obtained from sensing measurements of the path based on the measurement object; phase differences obtained from sensing measurements of the same path based on different measurement objects; the difference between the first difference and the fitted straight line (which will be explained in conjunction with events later, but will not be elaborated here); the multipath resolution capability of the measurement object; the multipath resolution capability after at least one of the multiple measurement objects is replaced; the difference in multipath resolution capability before and after at least one of the multiple measurement objects is replaced; the multipath sidelobe level of the measurement object; the multipath sidelobe level after at least one of the multiple measurement objects is replaced; or the difference in multipath sidelobe level before and after at least one of the multiple measurement objects is replaced, etc., without specific limitations here. Alternatively, the reported quantity can be all or part of the measurement results obtained from measuring multiple measurement objects, or the reported quantity is the result obtained after intermediate processing (such as filtering or smoothing) of all or part of the measurement results.

[0269] The perceived target (e.g., the subsequent first perceived target) can also be called the target of interest. Furthermore, the perceived target can be replaced or equivalent to a path, meaning that measuring the perceived target can be replaced or equivalent to measuring a path. Each path can involve one or more perceived targets; the specific number is not limited here.

[0270] The characteristic can refer to strength and / or electromagnetic parameters (or electromagnetic properties), etc. Electromagnetic parameters can include one or more of the following: conductivity, permeability, or dielectric constant, etc., without specific limitations here. Additionally, the aforementioned strength can be referred to as the target strength or the strength of the radius. For ease of description, the following description will use strength as an example.

[0271] Multipath resolution capability, also known as multipath resolution level or multipath resolution information, includes one or more of the following: the number of multipaths or multipath density, etc., without specific limitations here. Additionally, multipath density can refer to one or more of the following: the maximum density among multiple densities corresponding to a multipath (i.e., the maximum density of the multipath), the minimum density among multiple densities corresponding to a multipath (i.e., the minimum density of the multipath), the average density among multiple densities corresponding to a multipath (i.e., the average density of the multipath), the variance of multiple densities corresponding to a multipath (i.e., the variance density of the multipath), or the standard deviation of multiple densities corresponding to a multipath (i.e., the standard deviation density of the multipath), etc. Multipath resolution capability will be further explained in conjunction with the S5 event later; it will not be elaborated on here.

[0272] Multipath sidelobe level, also known as multipath sidelobe descent level, multipath sidelobe capability, or multipath sidelobe information, includes one or more of the following: peak multipath sidelobe ratio or multipath sidelobe descent rate, etc., without specific limitations here. Multipath sidelobe level can also refer to one or more of the following: maximum multipath sidelobe descent rate, minimum multipath sidelobe descent rate, or average multipath sidelobe descent rate, etc. The multipath sidelobe level will be further explained in conjunction with the S6 event later, and will not be elaborated on here.

[0273] Optionally, the above-mentioned "based on the measurement object" can be understood as: on the first measurement object, or on the frequency band used by the first measurement object, or on the resources used by the first measurement object, etc. For example, the characteristics obtained by sensing the first target based on the first measurement object can be understood as: the characteristics obtained by sensing the first target based on the first measurement object; or as: the characteristics obtained by sensing the first target based on the frequency band used by the first measurement object; or as: the characteristics obtained by sensing the first target based on the resources used by the first measurement object, etc.

[0274] 2. Reference signal type (RS type).

[0275] The reference signal type may include one or more of the following: synchronization signal block (SSB), channel state information reference signal (CSI-RS), positioning reference signal (PRS), sounding reference signal (SRS), or reference signal used for sensing, etc., without being limited here.

[0276] For example, reference signals can be specifically divided into uplink reference signals or downlink reference signals. Among them, uplink reference signals can include one or more of the following: channel sounding reference signal (SRS), physical uplink control channel (PUCCH)-demodulation reference signal (DMRS) (PUCCH-DMRS), physical uplink share channel (PUSCH)-demodulation reference signal (PUSCH-DMRS), phase noise tracking reference signal (PTRS), or uplink reference signals used for sensing, etc. Downlink reference signals may include one or more of the following: SSB, CSI-RS, physical downlink control channel (PDCCH)-demodulation reference signal (PDCCH-DMRS), physical downlink share channel (PDSCH)-demodulation reference signal (PDSCH-DMRS), PTRS, cell reference signal (CRS) in LTE, tracking reference signal (TRS) in NR, downlink positioning reference signal (DL-PRS), or downlink reference signals used for sensing, etc.

[0277] 3. Report format.

[0278] The reporting format can include the relationship between reporting quantities. For example, reporting format 1 is used to indicate that reporting quantity 1 is associated with reporting quantity 2 or reporting quantity 3, etc. The specifics are not limited here.

[0279] 4. Report type.

[0280] Reporting types are divided into event-triggered and periodic-triggered types.

[0281] For ease of description, the following description will only use event triggering as an example. In other embodiments, the terminal device can also be triggered to report measurement reports periodically, which is not limited here.

[0282] 5. At least one threshold corresponding to the event.

[0283] The at least one threshold corresponding to an event may include one or more of the following: at least one event threshold (Threshold), hysteresis threshold (Hys), time hysteresis (TimeToTrigger) corresponding to the event, or result bias (Off) corresponding to the event, etc., without being limited here. The following description will only use the event threshold and hysteresis threshold as examples. Furthermore, the thresholds or hysteresis thresholds in the embodiments of this application may be the same or different.

[0284] Optionally, at least one threshold corresponding to an event can also be distinguished into a threshold corresponding to an event entry condition and a threshold corresponding to an event exit condition (or exit condition).

[0285] To differentiate the thresholds corresponding to different events, we will use terms such as first threshold, second threshold, and third threshold to distinguish the thresholds for different events. For example, the threshold involved in subsequent event S1 can be called the first threshold, and the hysteresis threshold involved in event S1 can be called the first hysteresis threshold and the second hysteresis threshold, etc. We will describe one or more thresholds corresponding to different events later, but we will not elaborate on that here.

[0286] It is understood that the above parameters are just examples. In other embodiments, the first information may also include other parameters (such as cell list, measurement gaps, etc.), which are not limited here.

[0287] The above examples illustrate the MO parameters in Table 1 and the RC parameters in Table 2. To reduce the number of indication bits in the first information, Table 3 can also indicate the combination of MO and RC parameters. For example, Tables 1 and 2 are pre-configured, and the first information only indicates the measurement identifier, which corresponds to the relevant MO and RC parameters.

[0288] For example, one example of Table 3 is as follows:

[0289] Table 3

[0290] Here, a measurement identifier of 1 indicates that both the measurement object identifier and the reporting configuration identifier are 1. Specifically, a measurement identifier of 1 indicates that: the measurement object identifier is 1, and the carrier frequency corresponding to this measurement object identifier is 3500MHz, the allowed measurement bandwidth is 100MHz, and the SCS is 30KHz. It also indicates that the event identifier is S1, the threshold corresponding to S1 is the first threshold, the reference signal type is PRS, and the reported quantity is based on the intensity / intensity difference measured by the measurement object.

[0291] A measurement identifier of 2 indicates that the measurement object identifier is 2 and the reporting configuration identifier is 1. Specifically, a measurement identifier of 2 indicates that: the measurement object identifier is 2, and the carrier frequency corresponding to this measurement object identifier 2 is 3500MHz, the allowed measurement bandwidth is 100MHz, and the SCS is 15kHz. It also indicates that the event identifier is S1, the threshold corresponding to S1 is the first threshold, the reference signal type is PRS, and the reported quantity is the intensity / intensity difference measured by the measurement object. In other words, the configuration in this example is for the S1 event.

[0292] It is understood that the above is only an exemplary description using the S1 event as an example. In other embodiments, it may also be a configuration for one or more of the S1 to S6 events, which is not limited here.

[0293] The parameters that the first information may indicate have been described above. The events related to the first information in the embodiments of this application are described below.

[0294] For ease of description, the following example uses multiple measurement objects, including a first measurement object and a second measurement object, to illustrate the event, and the first measurement object and the second measurement object use different frequency bands.

[0295] Correspondingly, in accordance with the aforementioned explanation of the measurement object, the resources used by the first measurement object and the second measurement object can be CC, FL, or BWP, etc.

[0296] The event identifiers in this application embodiment include one or more of the following: a first identifier, a second identifier, a third identifier, a fourth identifier, a fifth identifier, or a sixth identifier. Wherein, the first identifier corresponds to event S1, the second identifier corresponds to event S2, the third identifier corresponds to event S3, the fourth identifier corresponds to event S4, the fifth identifier corresponds to event S5, and the sixth identifier corresponds to event S6.

[0297] To gain a more intuitive understanding of each event, we will first describe the definition (description), physical meaning, and measurable quantity of each event in conjunction with Table 4, and then describe the entry and exit conditions of each event in conjunction with Table 5.

[0298] Table 4

[0299] In Table 4, 1, 2, and 3 refer to possible scenarios, which can be implemented individually or in combination. No specific restrictions are set here.

[0300] Table 5

[0301] The events S1 to S6 are described below with reference to Tables 4 and 5. HA, for events S1 and S2.

[0302] First, describe events S1 and S2 in conjunction with Table 4.

[0303] Event S1 refers to the following: the intensity difference (or intensity difference value) obtained by measuring the first perceived target based on the first measurement object and the second measurement object is less than or equal to the first threshold.

[0304] Event S2 refers to the following: the intensity difference obtained from measuring the first perceived target using the first measurement object and the second measurement object is greater than or equal to the second threshold.

[0305] The physical meaning of events S1 and S2 is the difference in characteristics exhibited by the same perceived target on different measurement objects. For example, the physical meaning of event S1 is that the difference in characteristics exhibited by the same perceived target on different measurement objects is not significant. Therefore, different measurement objects can be coherently synthesized. Conversely, the physical meaning of event S2 is that the difference in characteristics exhibited by the same perceived target on different measurement objects is significant. Therefore, different measurement objects cannot be coherently synthesized.

[0306] Among them, the intensity difference obtained by measuring the first perceived target using the first measurement object and the second measurement object can be described in several equivalent ways:

[0307] For example, the difference between the intensity obtained by perceiving and measuring the first sensing target based on the first measurement object and the intensity obtained by perceiving and measuring the first sensing target based on the second measurement object.

[0308] For example, the difference between the intensity obtained by sensing and measuring multipath based on a first measurement object and the intensity obtained by sensing and measuring multipath based on a second measurement object.

[0309] For example, the difference between the intensity obtained by perceiving and measuring the first target on the first measurement object and the intensity obtained by perceiving and measuring the first target on the second measurement object.

[0310] For example, the difference between the intensity obtained by sensing the first target in the frequency band used by the first measurement object and the intensity obtained by sensing the first target in the frequency band used by the second measurement object.

[0311] For example, the difference between the intensity obtained by perceiving and measuring the first sensing target on the resources used by the first measurement object and the intensity obtained by perceiving and measuring the first sensing target on the resources used by the second measurement object.

[0312] For example, given a first perceived target or a first path, the changes in target characteristics observed on a first measurement object and a second measurement object.

[0313] For example, for a given first sensing target or first path, the changes in target characteristics observed in the frequency bands of the first and second measurement objects.

[0314] For example, given a first sensing target or a first path, the changes in target characteristics observed on the resources of the first and second measurement objects, etc., are not specifically limited here.

[0315] To more accurately analyze the differences or changes in target characteristics of different measurement objects, in the same scenario, the transmitting end uses the same transmission power to send transmission signals on both the first and second measurement objects. This transmitting end can be a terminal device or an access network device. The transmitting end and scenario can be referred to the description of the embodiment shown in Figure 6 above, and will not be repeated here.

[0316] For example, as shown in Figure 10, the frequency domain resource 1 and frequency domain resource 2 cannot be coherently synthesized because the differences in their observations of the same sensing target (or target of interest) are large.

[0317] Secondly, the events S1 and S2 are described in conjunction with Table 5.

[0318] a. Regarding event S1.

[0319] The entry condition of S1 (also referred to as S1-1) includes: the sum of the intensity difference and the first hysteresis threshold (i.e., Hsy1) is less than the first threshold; the exit condition of the first event (also referred to as S1-2) includes: the difference between the intensity difference and the second hysteresis threshold (i.e., Hsy2) is greater than the seventh threshold.

[0320] The first threshold and the seventh threshold can be the same or different, and the first hysteresis threshold and the second hysteresis threshold can be the same or different. For example, if the first threshold and the seventh threshold are different, the less than in the S1 entry condition can be replaced with less than or equal to, and the greater than in the S1 exit condition can be replaced with greater than or equal to.

[0321] For example, S1-1 is: |M1-M2|+Hys1<first threshold etc., and S1-2 is: |M1-M2|-Hys2>seventh threshold etc.

[0322] Where M1 is the intensity measured on the first perceived target based on the first measurement object. M2 is the intensity measured on the first perceived target based on the second measurement object. Hys1 and Hys2 are hysteresis parameters of S1, which can be defined, for example, in reportConfig. Furthermore, the unit of intensity can be dBm, etc. The units of Hys1 and Hys2 can be dB, etc. The units of the first threshold and the seventh threshold are the same as the units of M1.

[0323] It is understood that this description only covers the entry and exit conditions of S1, and other descriptions of S1 can be found in the previous descriptions. Furthermore, the entry and exit conditions described above are merely examples; other embodiments may have different methods, and their specific sources are not limited.

[0324] b. For event S2.

[0325] The entry condition for S2 (also referred to as S2-1) includes: the difference between the intensity difference and the third hysteresis threshold (i.e., Hsy3) is greater than the second threshold; the exit condition for the second event (also referred to as S2-2) includes: the sum of the intensity difference and the fourth hysteresis threshold (i.e., Hsy4) is less than the eighth threshold.

[0326] The second threshold and the eighth threshold can be the same or different, and the third hysteresis threshold and the fourth hysteresis threshold can be the same or different. For example, if the second threshold and the eighth threshold are different, the "greater than" in the S2 entry condition can be replaced with "greater than or equal to", and the "less than" in the S2 exit condition can be replaced with "less than or equal to".

[0327] Furthermore, the threshold of S2 can be the same as or different from the threshold of S1. For example, the second threshold of S2 can be the same as or different from the first threshold of S1. As another example, the second threshold of S2 can be the same as or different from the seventh threshold of S1. As another example, the eighth threshold of S2 can be the same as or different from the seventh threshold of S1. As another example, the eighth threshold of S2 can be the same as or different from the first threshold of S1.

[0328] For example, S2-1 is: |M1-M2|-Hys3>second threshold, etc., and S2-2 is: |M1-M2|+Hys4<eighth threshold, etc.

[0329] Where M1 is the intensity measured on the first perceived target based on the first measurement object. M2 is the intensity measured on the first perceived target based on the second measurement object. Hys3 and Hys4 are hysteresis parameters of S2, which can be defined, for example, in reportConfig. Furthermore, the unit of intensity can be dBm, etc. The units of Hys3 and Hys4 can be dB, etc. The units of the second threshold and the eighth threshold are the same as the units of M1.

[0330] It is understood that this description only covers the entry and exit conditions of S2; other descriptions of S2 can be found in the previous descriptions. Furthermore, the entry and exit conditions described above are merely examples; other embodiments may have different methods, and their specific sources are not limited.

[0331] B. Regarding events S3 and S4.

[0332] First, describe events S3 and S4 in conjunction with Table 4.

[0333] Event S3 refers to: The difference between the first difference and the fitted straight line is less than or equal to the third threshold. Alternatively, the difference between the measured phase difference obtained from multipath measurements using the first and second measurement objects and the theoretical phase difference is less than or equal to the third threshold. Alternatively, the ranging resolution can be improved after combining multiple measurement objects. Alternatively, multiple measurement objects can be coherently combined. Alternatively, the phase differences obtained from multipath measurements using the first and second measurement objects lie on a straight line, or the line connecting the phase differences approximates a straight line.

[0334] Event S4 refers to: The difference between the first difference and the fitted straight line is greater than or equal to the fourth threshold. Alternatively, the difference between the measured phase difference obtained from multipath measurements using the first and second measurement objects and the theoretical phase difference is greater than or equal to the fourth threshold. Or, the ranging resolution after combining multiple measurement objects cannot be improved. Or, multiple measurement objects cannot be coherently combined. Or, the phase differences obtained from multipath measurements using the first and second measurement objects are not on a straight line, or the line connecting the phase differences cannot be approximated as a straight line.

[0335] The physical meaning of events S3 and S4 is whether the sensing system or the synesthetic system has the capability to coherently combine different measurement objects. For example, the physical meaning of event S3 is that the sensing system or the synesthetic system has the capability to coherently combine different measurement objects, or that the ranging resolution is improved after combining multiple measurement objects. Conversely, the physical meaning of event S4 is that the sensing system or the synesthetic system does not have the capability to coherently combine different measurement objects, or that the ranging resolution cannot be improved after combining multiple measurement objects.

[0336] The difference between the first difference and the fitted line can be understood as the calculated amount between the phase difference obtained by different measurement objects measuring the same sensing target and the fitted line. This calculated amount can be understood as one or more phase differences from the measured value to the fitted line (e.g., the phase difference in Figure 11 below). It can also be understood as one or more vertical distances from the measured value to the fitted line (e.g., d in Figure 12 below).

[0337] The measured phase can be understood as the phase difference obtained by measuring multipath signals using the first and second measurement objects. Alternatively, it can be understood as the phase difference obtained by measuring at least one sensing target using the first and second measurement objects. The theoretical phase can be understood as the phase difference obtained by fitting all or part of the measured phases.

[0338] The fitted line described above can be interpreted in several ways. For example, it can be a line fitted to the phase difference obtained by measuring the first path in a multipath using the first and second measurement objects. Another example is a line fitted to the phase difference obtained by measuring the first path in a multipath using the first and second measurement objects as a function of distance or time delay. Here, a path correlation has a distance or time delay. Alternatively, a path correlation may have a time delay and a corresponding phase difference.

[0339] In this context, the measurement results of multipath can be understood as complex numbers, encompassing both intensity and phase. The first path can be one, multiple, or all of the multipaths. For example, the first path can be the top N paths after sorting the multipaths by intensity from high to low, where N in this embodiment is a positive integer greater than 0. Alternatively, the first path can also be the top N paths after sorting the multipaths by intensity from low to high. Furthermore, the first path can be any N random paths, etc., without specific limitations here. Alternatively, the paths used to fit the straight line can be all the measured paths, or a subset of the measured multipaths, etc.

[0340] To facilitate understanding of the relationship between the fitted phase difference and the aforementioned fitted line, this paper will use CC as an example for subsequent descriptions. That is, frequency resource 1 is specifically CC1, and frequency resource 2 is specifically CC2.

[0341] For example, taking CC1 and CC2 as examples, assume that the center frequency of CC1 is f1 and the center frequency of CC2 is f2. For the same sensing target (or the same path), the propagation delay of the signal transmitted by the transmitter (TX) to the receiver (RX) after passing through the sensing target is τ. In addition to the phase introduced by the propagation delay, the transceiver system introduces phases ψ1 and ψ2 on CC1 and CC2, respectively. Then, at the receiver, for a sensing target with a time delay of τ, the corresponding phases on CC1 and CC2 can be expressed as: φ1(τ)=2πf1τ+ψ1; φ2(τ)=2πf2τ+ψ2;

[0342] Furthermore, the phase difference between the signals received on two CCs on the same sensing target can be expressed as: Δφ 12 (τ)=2πΔf 12 τ+Δψ 12 ;

[0343] The above equation is a linear equation, where Δf 12 and Δψ 12 To determine the value, Δφ 12 (τ) changes with τ. That is, when two CCs are coherent, the phase difference between the two CCs changes linearly with distance.

[0344] For example, taking the phase difference and five sensing targets or paths as an example, the measured values ​​obtained from CC1 and CC2, and the straight line (i.e., the fitted line or theoretical phase) obtained by fitting the measured values, can be shown in Figure 11. That is, for a sensing target, the horizontal axis is the distance corresponding to the sensing target, and the vertical axis is the phase obtained by measuring the sensing target on CC1 and CC2. Then, for five sensing targets, assuming that the distances corresponding to the five sensing targets are different, that is, each sensing target will correspond to a point in a two-dimensional plane (including two values, one value is the distance or time delay, and the other value is the phase difference). Theoretically, if CC1 and CC2 can be coherently synthesized, the phase difference of these five sensing targets should be on a straight line (i.e., the straight line represented by the linear equation above).

[0345] For example, a phase difference is obtained by measuring a single sensing target using multiple measurement objects. Conversely, multiple phase differences can be obtained by measuring multiple sensing targets using multiple measurement objects. If the multiple measurement objects can be coherently combined, or if the ranging resolution after combining the multiple measurement objects can be improved, then the multiple phase differences should be on a straight line. If the multiple measurement objects cannot be coherently combined, or if the ranging resolution after combining the multiple measurement objects cannot be improved, then the multiple phase differences will not be on a straight line.

[0346] For example, taking the vertical distance (d) and five sensing targets or paths as an example, the measured values ​​obtained from CC1 and CC2, and the straight line fitted by the measured values ​​(i.e., the fitted line or theoretical phase), can be shown in Figure 12. That is, for a sensing target, the horizontal axis is the distance corresponding to that sensing target, and the vertical axis is the phase obtained by measuring the sensing target on CC1 and CC2. Theoretically, if CC1 and CC2 can be coherently combined, the phase difference of multiple sensing targets should be on a straight line (i.e., the straight line represented by the linear equation mentioned above). Therefore, the fitted line obtained by fitting the measured values ​​should be a theoretically coherently combined line. The difference from coherent combination can be reflected by the vertical distance d from the measured value to the fitted line. For example, in this example, the difference can be measured by the computational cost of 5 d values ​​corresponding to 5 sensing targets. This computational cost can include one or more of the following: maximum value, average value, square root of square, or multiplication, etc.

[0347] Correspondingly, the phase difference is one or more distances from multiple measured values ​​to the fitted straight line, and the multiple measured values ​​are multiple phase differences obtained by measuring the multipath based on the first and second measured objects.

[0348] Correspondingly, event S3 occurs when the calculated value of multiple distances is less than or equal to a third threshold. Event S4 occurs when the calculated value of multiple distances is greater than or equal to a fourth threshold. Alternatively, event S3 can be understood as follows: event S3 indicates that the phase differences obtained from multipath measurements using the first and second measurement objects are on a straight line, or the line connecting the phase differences approximates a straight line. Event S4 indicates that the phase differences obtained from multipath measurements using the first and second measurement objects are not on a straight line, or the line connecting the phase differences cannot approximate a straight line.

[0349] Among them, multiple distances are the distances between multiple measured phase differences and the fitted straight lines obtained by fitting multiple phase differences. The calculated values ​​may include one or more of the following: maximum value, minimum value, average value, variance, standard deviation, square root of the sum of squares or multiplication value, etc.

[0350] Secondly, events S3 and S4 are described in conjunction with Table 5.

[0351] c. For event S3.

[0352] The entry condition for S3 (also denoted as S3-1) includes: the sum of the first difference and the fifth hysteresis threshold (i.e., Hsy5) is less than the third threshold; the exit condition for the third event (also denoted as S3-2) includes: the difference between the first difference and the sixth hysteresis threshold (i.e., Hsy6) is greater than the ninth threshold. The first difference is one or more distances from multiple measurements to the fitted straight line; the multiple measurements are multiple phase differences obtained by measuring the multipath based on the first and second measurement objects.

[0353] Among them, the third threshold and the ninth threshold can be the same or different, and the fifth hysteresis threshold and the sixth hysteresis threshold can be the same or different. For example, when the third threshold and the ninth threshold are different, the less than in the S3 entry condition can be replaced with less than or equal to, and the greater than in the S3 exit condition can be replaced with greater than or equal to.

[0354] For example, S3-1 includes one or more of the following:

[0355] (1)

[0356] (2) Max{|Δφ 12 (n)-kτ(n)-Δψ|}+Hys5<Third threshold;

[0357] (3) std{Δφ 12 (n)-kτ(n)-Δψ}+Hys5<Third threshold;

[0358] (4) var{Δφ 12 (n)-kτ(n)-Δψ}+Hys5<Third threshold;

[0359] (5)

[0360] (6) Max{d n |}+Hys5<Third threshold, etc.

[0361] S3-2 includes one or more of the following:

[0362] (1)

[0363] (2) Max{|Δφ 12 (n)-kτ(n)-Δψ|}-Hys6> Ninth threshold;

[0364] (3) std{Δφ 12 (n)-kτ(n)-Δψ}-Hys6> Ninth threshold;

[0365] (4) var{Δφ 12 (n)-kτ(n)-Δψ}-Hys6> Ninth threshold;

[0366] (5)

[0367] (6) Max{d n |}-Hys6> Ninth threshold, etc.

[0368] Where N is the number of multipaths, and n is the index of any one of the multipaths, where n is greater than 0 and less than or equal to N. Δφ 12 (n) represents the phase difference obtained by measuring the nth path based on the first and second measurement objects (bias can be considered or not), k is the slope of the fitted line, τ is the propagation delay of the signal emitted by the transmitter on the nth path (which can also be replaced by d = c * τ, where c is the speed of light), Δψ is the height of the line passing through the phase axis (e.g., the intersection of the extension of the fitted line and the vertical axis in Figure 11), d n Hys5 represents the vertical distance from the nth sensing target to the fitted line (the line obtained by fitting the measured values ​​of the n sensing targets) (e.g., d in Figure 12), Hys5 is the fifth hysteresis threshold, Hys6 is the sixth hysteresis threshold, Max indicates taking the maximum value, std indicates taking the standard deviation, and var indicates taking the variance.

[0369] It is understood that the above formulas and descriptions are based on the example of n starting from 1. In other embodiments, n may also start from 0, which is not limited here.

[0370] Optionally, Δφ 12(n) and Δψ can be expressed in degrees or radians, τ in nanoseconds or seconds, d in meters or kilometers, etc. The units of the third threshold, Hys5, Hys6, and the ninth threshold are the same as those of Δφ. 12 (n) has the same unit.

[0371] It is understood that this description only covers the entry and exit conditions for S3; other descriptions of S3 can be found in the previous descriptions. Furthermore, the entry and exit conditions described above are merely examples; other embodiments may have different methods, and their specific sources are not limited.

[0372] d. For event S4.

[0373] The entry condition for S4 (also referred to as S4-1) includes: the difference between the first difference and the seventh hysteresis threshold (i.e., Hsy7) is greater than the fourth threshold; the exit condition for the fourth event (also referred to as S4-2) includes: the sum of the first difference and the eighth hysteresis threshold (i.e., Hsy8) is less than the tenth threshold; the first difference is one or more distances from multiple measurements to the fitted straight line; the multiple measurements are multiple phase differences obtained by measuring the multipath based on the first measurement object and the second measurement object.

[0374] Among them, the fourth threshold and the tenth threshold can be the same or different, and the seventh hysteresis threshold and the eighth hysteresis threshold can be the same or different. For example, when the fourth threshold and the tenth threshold are different, "greater than" in the S4 entry condition can be replaced with "greater than or equal to", and "less than" in the S4 exit condition can be replaced with "less than or equal to".

[0375] Furthermore, the threshold of S4 can be the same as or different from the threshold of S3. For example, the fourth threshold of S4 can be the same as or different from the third threshold of S3. As another example, the fourth threshold of S4 can be the same as or different from the ninth threshold of S3. As another example, the tenth threshold of S4 can be the same as or different from the ninth threshold of S3. As another example, the tenth threshold of S4 can be the same as or different from the third threshold of S3.

[0376] For example, S4-1 includes one or more of the following:

[0377] (1)

[0378] (2) Max{|Δφ 12 (n)-kτ(n)-Δψ|}-Hys7>Fourth threshold;

[0379] (3) std{Δφ 12 (n)-kτ(n)-Δψ}-Hys7>Fourth threshold;

[0380] (4) var{Δφ12 (n)-kτ(n)-Δψ}-Hys7>Fourth threshold;

[0381] (5)

[0382] (6) Max{d n |}-Hys7> Fourth threshold, etc.

[0383] S4-2 includes one or more of the following:

[0384] (1)

[0385] (2) Max{|Δφ 12 (n)-kτ(n)-Δψ|}+Hys8<tenth threshold;

[0386] (3) std{Δ+ 12 (n)-kτ(n)-Δψ}+Hys8<tenth threshold;

[0387] (4) var{Δφ 12 (n)-kτ(n)-Δψ}+Hys8<tenth threshold;

[0388] (5)

[0389] (6) Max{d n |}+Hys8<10th threshold, etc.

[0390] Where N is the number of multipaths, n is the index of any one of the multipaths, and Δφ 12 (n) represents the phase difference obtained by measuring the nth path based on the first and second measurement objects (bias can be considered or not), k is the slope of the fitted line, τ is the propagation delay of the signal emitted by the transmitter on the nth path (which can also be replaced by d = c * τ, where c is the speed of light), Δψ is the height of the line passing through the phase axis (e.g., the intersection of the extension of the fitted line and the vertical axis in Figure 11), d n Hys7 represents the vertical distance from the nth sensing target to the fitted line (the line obtained by fitting the measured values ​​of the n sensing targets). Hys7 is the seventh hysteresis threshold, Hys8 is the eighth hysteresis threshold, Max represents the maximum value, std represents the standard deviation, and var represents the variance.

[0391] Optionally, Δφ 12 (n) and Δψ can be expressed in degrees or radians, τ in nanoseconds or seconds, etc., and d in meters or kilometers, etc. The units of the fourth threshold, Hys7, Hys8, and the tenth threshold are the same as Δφ.12 (n) has the same unit.

[0392] It is understood that this description only covers the entry and exit conditions for S4, and other descriptions of S4 can be found in the previous descriptions. Furthermore, the entry and exit conditions described above are merely examples; other embodiments may have different methods, and their specific sources are not limited.

[0393] C. Regarding event S5.

[0394] First, describe the S5 event in conjunction with Table 4.

[0395] Event S5 refers to: the difference in multipath resolution between the third measurement object and the second measurement object among multiple measurement objects is greater than or equal to the fifth threshold. Alternatively, it can be understood as: the difference in multipath resolution before and after replacing the second measurement object with the third measurement object among multiple measurement objects is greater than or equal to the fifth threshold. Or, it can be understood as: there exist one or more measurement objects whose multipath resolution can be improved by replacing one or more measurement objects in the existing configuration.

[0396] The number of third measurement objects and second measurement objects can be one or more, and the number of third measurement objects and second measurement objects can be the same or different. Furthermore, the third measurement object can be indicated by the first information or a pre-configured object, etc., and is not specifically limited here.

[0397] The aforementioned multipath resolution difference refers to the difference between the multipath resolution of multiple measurement objects before replacement and the multipath resolution of multiple measurement objects after replacement. Alternatively, it can be understood as the difference between the original set of measurement objects and the new set of measurement objects obtained by replacing one or more of them.

[0398] As described above regarding multipath resolution, multipath resolution includes one or more of the following: the number of multipaths or multipath density. Correspondingly, the differences in multipath resolution can include one or more of the following: differences in the number of resolvable multipaths or differences in multipath density. Specifically, differences in multipath density can include one or more of the following: average density difference of multipaths, maximum density difference of multipaths, minimum density difference of multipaths, density variance difference of multipaths, or density standard deviation difference of multipaths.

[0399] For example, the average density is denoted as K / P, where K is the number of multipaths detected within a given distance (or range) P, and both K and P are real numbers greater than 0. For instance, if the range of interest is 300 meters, and the number of multipaths detected within 300 meters is 10, then K = 10, P = 300 meters. That is, the average density is 0.3.

[0400] For example, the maximum multipath density is denoted as max{Ki / Q}, where Ki is the number of multipaths detected within a given range Q, and both Ki and Q are real numbers greater than 0. For instance, if P includes multiple ranges Q, the range of interest P is 300 meters, and the given range Q is 10 meters, then the number of multipaths detected within 300 meters, Ki, is one of {0, 1, 3}, and the maximum multipath density is 3 / 10 = 0.3.

[0401] For example, taking the resource used by the measurement object as CC, the resource used by the third measurement object is CC1, and the resource used by the second measurement object is CC2. Assume that the existing configuration of multiple CCs includes C1, C2, and C3 (also referred to as the first CC set or C1C2C3). Replacing C2 in C1C2C3 with C4 yields C1, C4, and C3 (also referred to as the second CC set or C1C4C3). The aforementioned difference in multipath resolution refers to the difference between the multipath resolution of C1C2C3 and C1C4C3. In this example, C2 is the second measurement object, and C4 is the third measurement object.

[0402] For example, the number of multipaths that the first CC set can distinguish is A, and the number of multipaths that the second CC set can distinguish is B. That is, the number of distinguishable multipaths changes from A to B. Then, event S5 indicates that the value of B minus A is greater than or equal to the fifth threshold. In this example, A and B are integers greater than 0. As another example, the average multipath density that the first CC set can distinguish is A (i.e., K / P = A), and the average multipath density that the second CC set can distinguish is B. That is, the average multipath density that can distinguish changes from A to B. Then, event S5 indicates that the value of B minus A is greater than or equal to the fifth threshold. As yet another example, the maximum multipath density that the first CC set can distinguish is A, and the maximum multipath density that the second CC set can distinguish is B. That is, the maximum multipath density that can distinguish changes from A to B. Then, event S5 indicates that the value of B minus A is greater than or equal to the fifth threshold.

[0403] For example, as shown in Figure 13, the first CC set corresponds to the change, and the second CC set corresponds to the change. It can be seen that after the change, the second CC set can distinguish more multipaths, that is, the ranging resolution is improved.

[0404] Secondly, the S5 event is described in conjunction with Table 5.

[0405] The entry condition of S5 (which can also be denoted as S5-1) includes: the difference between the second difference and the ninth hysteresis threshold (i.e., Hsy9) is greater than the fifth threshold; the exit condition of the fifth event (which can also be denoted as S5-2) includes: the sum of the second difference and the tenth hysteresis threshold (i.e., Hsy10) is less than the eleventh threshold; the second difference is the multipath capability difference between the third measurement object and the second measurement object among multiple measurement objects.

[0406] Among them, the fifth threshold and the eleventh threshold can be the same or different, and the ninth hysteresis threshold and the tenth hysteresis threshold can be the same or different. For example, when the fifth threshold and the eleventh threshold are different, "greater than" in the S5 entry condition can be replaced with "greater than or equal to", and "less than" in the S5 exit condition can be replaced with "less than or equal to".

[0407] For example, S5-1 is: BA-Hys9>the fifth threshold, etc., and S5-2 is: B-A+Hys10<the eleventh threshold, etc.

[0408] Where A represents the multipath resolution capability of multiple measurement objects before the change, B represents the multipath resolution capability of multiple measurement objects after the change, Hys9 is the ninth hysteresis threshold, and Hys10 is the tenth hysteresis threshold. For example, A and B can refer to the previously described number of detected paths, average path density, or maximum path density. Multiple measurement objects before the change can refer to multiple already configured measurement objects, while multiple measurement objects after the change refer to the multiple measurement objects after replacing the second measurement object with a third measurement object.

[0409] It is understood that this description only covers the entry and exit conditions for S5; other descriptions of S5 can be found in the previous descriptions. Furthermore, the entry and exit conditions described above are merely examples; other embodiments may have different methods, and their specific sources are not limited.

[0410] D. Regarding event S6.

[0411] First, describe event S6 in conjunction with Table 4.

[0412] Event S6 refers to: the difference in multipath sidelobe levels between the third measurement object and the second measurement object among multiple measurement objects is greater than or equal to the sixth threshold. Alternatively, it can be understood as: the difference in multipath sidelobe levels before and after replacing the second measurement object with the third measurement object among multiple measurement objects is greater than or equal to the sixth threshold. Or, it can be understood as: there exist one or more measurement objects whose multipath sidelobe levels can be improved by replacing one or more measurement objects in the existing configuration.

[0413] The number of the third measurement object and the number of the second measurement object can be one or more, and the number of the third measurement object and the number of the second measurement object can be the same or different.

[0414] The aforementioned multipath sidelobe level difference refers to the difference between the multipath sidelobe levels of multiple measurement objects before replacement and the multipath sidelobe levels of multiple measurement objects after replacement. Alternatively, it can be understood as follows: if an existing set of measurement objects is replaced with one or more of its measurement objects to obtain a new set of measurement objects, then the multipath resolution difference is the difference in multipath sidelobe levels between the original set of measurement objects and the new set of measurement objects.

[0415] As described above regarding multipath sidelobe levels, these levels include one or more of the following: peak-to-sidelobe ratio or sidelobe descent rate. For example, the peak-to-sidelobe ratio can also be called PSLR (peakH-sideH-lobe ratio), and the sidelobe descent rate can also be called SLDR (sideH-lobe-dropH ratio). Correspondingly, the differences in multipath sidelobe levels can include one or more of the following: differences in peak-to-sidelobe ratio or differences in sidelobe descent rate. Specifically, differences in sidelobe descent rate can include one or more of the following: the maximum value of the sidelobe descent rate, the minimum value of the sidelobe descent rate, or the average value of the sidelobe descent rate.

[0416] It should be noted that the multipath sidelobe level difference in S6 can refer to either the difference between the multipath sidelobe level before and after replacement, or vice versa. For example, for the peak-to-sidelobe ratio, a smaller value after replacement is better. Therefore, the peak-to-sidelobe ratio difference refers to the difference between the peak-to-sidelobe ratio before and after replacement. Similarly, for the sidelobe descent rate, a larger value after replacement is better. Therefore, the sidelobe descent rate difference refers to the difference between the sidelobe descent rate before and after replacement.

[0417] For example, the sidelobe descent rate of a multipath trajectories is defined as the descent of a sidelobe relative to another sidelobe at a given distance P. For instance, if P = 5 meters, there is a target amplitude of X dBm at a distance of 20 meters, and the sidelobe amplitude is Y dBm at a distance of 25 meters. In this case, the sidelobe descent rate is defined as (XY) / P, and the unit can be dB / m or dBm / m.

[0418] For example, the first CC set and the second CC set in event S5 above are continued.

[0419] For example, the peak-to-side-lobe ratio (PNR) of the first CC set is E, and the PNR of the second CC set is F. That is, the PNR changes from E to F. Then, event S6 indicates that the value of E minus F is greater than or equal to the sixth threshold. In this example, E and F are integers greater than 0. Therefore, event S6 indicates that the value of E minus F is greater than or equal to the sixth threshold.

[0420] For example, the sidelobe descent rate of the first CC set is E, and the sidelobe descent rate of the second CC set is F. That is, the sidelobe descent rate changes from E to F. Then, event S6 indicates that the value of F minus E is greater than or equal to the sixth threshold. In this example, E and F are integers greater than 0. Therefore, event S6 indicates that the value of F minus E is greater than or equal to the sixth threshold.

[0421] For example, as shown in Figure 14, the first CC set corresponds to the set before the change, and the second CC set corresponds to the set after the change. It can be seen that the sidelobe level of the second CC set decreased after the change. As shown in Figure 13 above, the first CC set corresponds to the set before the change, and the second CC set corresponds to the set after the change. It can be seen that although the ranging resolution of the second CC set did not improve after the change, the ranging sidelobes decreased.

[0422] Secondly, the S6 event is described in conjunction with Table 5.

[0423] The entry condition for S6 (also referred to as S6-1) includes: the difference between the third difference and the eleventh hysteresis threshold (i.e., Hsy11) is greater than the sixth threshold; the exit condition for the sixth event (also referred to as S6-2) includes: the sum of the second difference and the twelfth hysteresis threshold (i.e., Hsy12) is less than the twelfth threshold; the third difference is the multipath sidelobe level difference between the third measurement object and the second measurement object among multiple measurement objects.

[0424] Among them, the sixth threshold and the twelfth threshold can be the same or different, and the eleventh hysteresis threshold and the twelfth hysteresis threshold can be the same or different. For example, when the sixth threshold and the twelfth threshold are different, the "greater than" in the S6 entry condition can be replaced with "greater than or equal to", and the "less than" in the S6 exit condition can be replaced with "less than or equal to".

[0425] Furthermore, the threshold of S6 can be the same as or different from the threshold of S5. For example, the sixth threshold of S6 can be the same as or different from the fifth threshold of S5. Similarly, the sixth threshold of S6 can be the same as or different from the eleventh threshold of S5. Likewise, the twelfth threshold of S6 can be the same as or different from the eleventh threshold of S5. And again, the twelfth threshold of S6 can be the same as or different from the fifth threshold of S5.

[0426] For example, S6-1 includes one or more of the following:

[0427] Or Max{PSLR1(n)}-Max{PSLR2(n)}-Hys11>the sixth threshold;

[0428] or

[0429] Or Max{SLDR2(n)-SLDR1(n)}-Hys11>sixth threshold, etc.

[0430] S6-2 includes one or more of the following:

[0431] Or Max{PSLR1(n)}-Max{PSLR2(n)}+Hys12<the twelfth threshold;

[0432] or

[0433] Or Max{SLDR2(n)-SLDR1(n)}+Hys12<the twelfth threshold, etc.

[0434] Where N is the number of multipaths, n is the index of any one of the multipaths, PSLR1(n) represents the PSLR obtained by measuring the nth path from multiple measurement objects before the change, PSLR2(n) represents the PSLR obtained by measuring the nth path from multiple measurement objects after the change, SLDR1(n) represents the SLDR obtained by measuring the nth path from multiple measurement objects before the change, SLDR2(n) represents the SLDR obtained by measuring the nth path from multiple measurement objects after the change, Hys11 is the eleventh hysteresis threshold, Hys12 is the second hysteresis threshold, and Max indicates taking the maximum value. Multiple measurement objects before the change can refer to multiple already configured measurement objects, while multiple measurement objects after the change refer to the multiple measurement objects after replacing the second measurement object in the multiple measurement objects with the third measurement object.

[0435] It is understood that this description only covers the entry and exit conditions for S6; other descriptions of S6 can be found in the previous descriptions. Furthermore, the entry and exit conditions described above are merely examples; other embodiments may have different methods, and their specific sources are not limited.

[0436] It is understood that the above-mentioned events are just examples, and other events may occur in other embodiments, which are not limited here.

[0437] Additionally, it should be noted that the above events can be configured individually or in combination; specific configurations are not limited here. For example, S1 and S3 can be combined. Similarly, S2 and S4 can be combined. S5 and S6 can be combined. Other examples include S1 and S2, S3 and S4, S1, S2, and S3, S1, S2, and S4, S1, S3, and S4, S1 and S5, S1 and S6, S1, S5, and S6, S1, S2, S3, and S4, S1, S2, S3, S4, and S5, and so on. When at least two of the above events are combined, the entry and exit conditions corresponding to the events can also be combined. Furthermore, the threshold of the combined event can be the same as or different from the thresholds of at least two events. For example, when S1 and S3 are combined, they can be called event S1S3. The threshold of S1S3 can be the same as the thresholds of S1 and S3, meaning the threshold in event S1S2 is set entirely based on events S1 and S3. Alternatively, the threshold of S1S3 can be different from the thresholds of S1 and S3, meaning the threshold in event S1S3 is independent of the thresholds set in events S1 and S3. Similarly, the combined events can also be S2S4, S5S6, or S1S2S3S4, etc., without further limitation here.

[0438] Step 902: The terminal device sends a measurement report to the network device.

[0439] The terminal device sends a measurement report to the network device. Correspondingly, the network device receives the measurement report sent by the terminal device. This measurement report includes multiple sensing measurement results, each of which is related to multiple measurement objects.

[0440] In this context, each of the multiple sensing measurement results is related to multiple measurement objects. This can be understood as any single sensing measurement result being a result of joint sensing by multiple measurement objects.

[0441] Optionally, after receiving the first information, the terminal device performs a sensing measurement operation to obtain the sensing measurement result and sends a measurement report to the network device. The sensing measurement can be applied to the multiple scenarios shown in Figure 6 above, which will not be elaborated further here. Furthermore, the specific scenario can be determined through the first information or other information, or through pre-configuration, etc., and is not limited here. For example, the terminal device can determine the specific scenario based on the scenario identifier indicated by the first information. Another example is that the terminal device can determine the specific scenario based on pre-configuration. Yet another example is that the terminal device determines the specific scenario through other indication information, etc.

[0442] Furthermore, after acquiring the sensing measurement results, the terminal device first determines whether the triggering conditions for measurement reporting are met based on the sensing measurement results. If the triggering conditions are met, the terminal device sends a measurement report to the network device. Meeting the triggering conditions can also be understood as meeting the entry conditions for an event.

[0443] Optionally, this corresponds to the factors affecting perception performance analyzed in Figures 7A and 8C above. The perception measurement result may include one or more of the following: characteristics obtained by perceiving the first perception target based on the first measurement object; characteristics obtained by perceiving the first perception target based on the second measurement object; differences in characteristics obtained by perceiving the first perception target based on the first measurement object and the second measurement object; phase obtained by perceiving the first perception target based on the first measurement object; phase obtained by perceiving the first perception target based on the second measurement object; phase difference obtained by perceiving the first perception target based on the first measurement object and the second measurement object; first difference obtained by multipath measurement on the first measurement object and the second measurement object; whether the first measurement object and the second measurement object can be coherently synthesized; multipath resolution capability between the third measurement object and the second measurement object among multiple measurement objects; differences in multipath resolution capability between the third measurement object and the second measurement object among multiple measurement objects; multipath sidelobe level between the third measurement object and the second measurement object among multiple measurement objects; differences in multipath sidelobe level between the third measurement object and the second measurement object among multiple measurement objects, etc., without specific limitations here.

[0444] The following is a brief description of the triggering conditions, entry conditions, and exit conditions for different events on the terminal device side. For relevant content, please refer to the description in step 901 above, which will not be repeated here.

[0445] Example 1: The event identifier indicated by the first information is the first identifier. The triggering conditions for reporting the measurement report include: the intensity difference obtained by measuring the first sensing target on the first measurement object and the second measurement object respectively is less than or equal to a first threshold. Or, the intensity difference obtained by measuring the first diameter on the first measurement object and the second measurement object respectively is less than or equal to a first threshold.

[0446] Alternatively, it can be understood that for the event identifier S1 indicated by the first information, the terminal device performs measurements based on the parameters corresponding to S1. For example, the terminal device may directly report the obtained perception measurement results. Or, the terminal device may report the obtained perception measurement results according to its own needs. Or, the terminal device may periodically report the obtained perception measurement results. Or, if the triggering condition of S1 is met, the terminal device reports the obtained perception measurement results. Or, when S1-1 is met, the entry condition of S1 is considered to be met. Correspondingly, when S1-2 is met, the exit condition of S1 is considered to be met.

[0447] Example 2: The event identifier indicated by the first information is the second identifier. The triggering conditions for reporting the measurement report include: the intensity difference obtained from multipath measurements on the first and second measurement objects is greater than or equal to a second threshold; or the intensity difference obtained from measurements of the first diameter on the first and second measurement objects is greater than or equal to a second threshold.

[0448] Alternatively, it can be understood that for the event identifier S2 indicated by the first information, the terminal device performs measurements based on the parameters corresponding to S2. For example, the terminal device directly reports the obtained perception measurement results. Another example is that the terminal device reports the obtained perception measurement results according to its own needs. Yet another example is that the terminal device periodically reports the obtained perception measurement results. Yet another example is that if the trigger condition of S2 is met, the terminal device reports the obtained perception measurement results. Yet another example is that when S2-1 is met, the entry condition of S2 is considered to be met. Correspondingly, when S2-2 is met, the exit condition of S2 is considered to be met.

[0449] Example 3: The event identifier indicated by the first information is the third identifier, and the triggering conditions for the measurement report include: the first difference is less than or equal to the third threshold.

[0450] Alternatively, it can be understood that for the event identifier S3 indicated by the first information, the terminal device performs measurements based on the parameters corresponding to S3. For example, the terminal device may directly report the obtained perception measurement results. Or, the terminal device may report the obtained perception measurement results according to its own needs. Or, the terminal device may periodically report the obtained perception measurement results. Or, if the triggering condition of S3 is met, the terminal device reports the obtained perception measurement results. Or, when S3-1 is met, the entry condition of S3 is considered to be met. Correspondingly, when S3-2 is met, the exit condition of S3 is considered to be met.

[0451] Example 4: The event identifier indicated by the first information is the fourth identifier, and the triggering conditions for the measurement report include: the first difference is greater than or equal to the fourth threshold.

[0452] Alternatively, it can be understood that for the event identifier S4 indicated by the first information, the terminal device performs measurements based on the parameters corresponding to S4. For example, the terminal device may directly report the obtained perception measurement results. Or, the terminal device may report the obtained perception measurement results according to its own needs. Or, the terminal device may periodically report the obtained perception measurement results. Or, if the triggering condition of S4 is met, the terminal device reports the obtained perception measurement results. Or, when S4-1 is met, the entry condition of S4 is considered to be met. Correspondingly, when S4-2 is met, the exit condition of S4 is considered to be met.

[0453] Example 5: The event identifier indicated by the first information is the fifth identifier. The triggering conditions for the measurement report include: the difference in multipath resolution between the third measurement object and the second measurement object among multiple measurement objects is greater than or equal to the fifth threshold.

[0454] Alternatively, this can be understood as follows: for the event identifier S5 indicated by the first information, the terminal device performs measurements based on the parameters corresponding to S5. For example, the terminal device may directly report the obtained perception measurement results. Alternatively, the terminal device may report the obtained perception measurement results according to its own needs. Alternatively, the terminal device may periodically report the obtained perception measurement results. Alternatively, if the trigger condition of S5 is met, the terminal device reports the obtained perception measurement results. Alternatively, when S5-1 is met, the entry condition of S5 is considered to be met. Correspondingly, when S5-2 is met, the exit condition of S5 is considered to be met.

[0455] Example 6: The event identifier indicated by the first information is the sixth identifier. The triggering conditions for the measurement report include: the difference in multipath sidelobe level between the third measurement object and the second measurement object among multiple measurement objects is greater than or equal to the sixth threshold.

[0456] Alternatively, it can be understood that for the event identifier S6 indicated by the first information, the terminal device performs measurements based on the parameters corresponding to S6. For example, the terminal device may directly report the obtained perception measurement results. Or, the terminal device may report the obtained perception measurement results according to its own needs. Or, the terminal device may periodically report the obtained perception measurement results. Or, if the triggering condition of S6 is met, the terminal device reports the obtained perception measurement results. Or, when S6-1 is met, the entry condition of S6 is considered to be met. Correspondingly, when S6-2 is met, the exit condition of S6 is considered to be met.

[0457] It should be noted that the above examples are merely illustrative. In other embodiments, the first information may also indicate an identifier for a combination of at least two events, etc., which is not limited here. For example, the event identifier indicated by the first information includes a first identifier and a third identifier, i.e., an event combining S1 and S3 (i.e., S1S3). Then the triggering conditions reported in the measurement report include the triggering condition of S1 or S1-1 or the triggering condition of S3 or S3-3.

[0458] In this embodiment, the terminal device determines an event identifier associated with multiple measurement objects through first information. The event identifier is related to the multiple measurement objects, and at least two of the measurement objects use different frequency bands. After determining the event identifier and the multiple measurement objects, the terminal device sends a measurement report. This report includes multiple sensing measurement results, and each of the multiple sensing measurement results is related to multiple measurement objects. On the one hand, multi-band sensing is beneficial for improving sensing performance. On the other hand, since each of the multiple sensing measurement results is related to multiple measurement objects, any single sensing measurement result can characterize the measurement result of joint sensing of multiple measurement objects. Furthermore, the joint sensing measurement results reported by the terminal device can also provide a reference for network devices to manage frequency bands.

[0459] The communication method in the embodiments of this application has been described above. The communication device in the embodiments of this application is described below. Please refer to Figure 15, which shows an embodiment of the communication device 1500 in this application.

In this application embodiment, the communication device 1500 can be a communication device, or it can be an integrated circuit or component inside the communication device, such as a chip. The communication device 1500 includes: a transceiver unit 1501. Alternatively, the communication device 1500 includes: a transceiver unit 1501 and a processing unit 1502. The transceiver unit 1501 is used to perform operations related to the transmission and reception of the terminal device or network device in the above method embodiments, and the processing unit 1502 is used to perform other operations of the terminal device or network device in the above method embodiments besides the transmission and reception operations.

[0465] In this embodiment, the terminal device determines an event identifier and multiple measurement objects based on the first information received by the transceiver unit 1501. The event identifier is associated with multiple measurement objects, and at least two of the measurement objects use different frequency bands. After determining the event identifier and multiple measurement objects, the terminal device sends a measurement report. This report includes multiple sensing measurement results, and each of the multiple sensing measurement results is associated with multiple measurement objects. On the one hand, multi-band sensing is beneficial for improving sensing performance. On the other hand, since each of the multiple sensing measurement results is associated with multiple measurement objects, any single sensing measurement result can characterize the measurement result of joint sensing of multiple measurement objects.

[0470] In this embodiment, the transceiver unit 1501 sends first information to enable the terminal device to determine that an event identifier is associated with multiple measurement objects, and that at least two of the measurement objects use different frequency bands. After determining the event identifier and multiple measurement objects, the terminal device sends a measurement report, which includes multiple sensing measurement results, each of which is associated with multiple measurement objects. On the one hand, multi-band sensing is beneficial for improving sensing performance. On the other hand, since each of the multiple sensing measurement results is associated with multiple measurement objects, any one sensing measurement result can characterize the measurement result of joint sensing of multiple measurement objects. Furthermore, the joint sensing measurement results reported by the terminal device can also provide a reference for network devices to manage frequency bands.
