[0003] This application relates to the field of communication technology, and in particular to a communication method and apparatus. Background Technology

[0004] Wireless sensing technology can obtain the characteristics of the signal propagation space by analyzing the changes in wireless signals during propagation, thereby enabling scene perception. Taking radar as an example, its basic principle is: the transmitter emits a specific waveform signal, which is transmitted to the receiver through a wireless channel. By combining the transmitted and received signals, the target of interest in the wireless channel can be extracted, thus achieving wireless sensing.

[0005] Wireless communication can be used to send and receive information between two ends. Its basic principle includes: the transmitter transmits a specific waveform signal, which is received by the receiver after passing through the wireless channel. The receiver processes the signal and demodulates the signal transmitted by the transmitter.

[0006] From the perspective of transmitting, receiving, and transmitting signals, wireless communication and wireless sensing are remarkably similar. Therefore, combining wireless communication and wireless sensing allows for simultaneous communication between the transmitting and receiving ends while simultaneously sensing the surrounding environment. Specifically, sensing signals can be transmitted in the frequency domain, which can be used to carry information exchanged between the transmitting and receiving ends, as well as to sense objects in the surrounding environment.

[0007] Further research is needed on how to configure resources for transmitting sensing signals. Summary of the Invention

[0008] This application provides a communication method and apparatus for configuring resources for transmitting sensing signals.

[0009] In a first aspect, embodiments of this application provide a communication method that can be applied to a first device. The first device can be a terminal or access network device, or a device within the terminal or access network device (e.g., a module, communication module, circuit or chip responsible for communication and / or sensing functions (such as a modem chip, also known as a baseband chip, or a system-on-chip (SoC) chip containing a modem core or a system-in-package (SIP) chip), a chip system, or a processor), or a logical node, logical module, or software capable of implementing all or part of the functions of the terminal or access network device. For ease of description, the following description uses a first device as an example. The method may include: the first device receiving first information, the first information indicating K configurations, each configuration including frequency band information and period information, where K is an integer greater than or equal to 2. The first device outputs a sensing signal based on the frequency band information and period information in each configuration.

[0010] Using this method, the first information can be configured to allocate resources for transmitting the sensing signal; correspondingly, the first device can accurately determine the resources for transmitting the sensing signal based on the first information. Furthermore, in this method, the first device can output the sensing signal based on frequency band information and periodic information from multiple configurations, thereby expanding the unambiguous range of speed measurement and reducing the overhead of sensing time-domain resources.

[0011] Secondly, embodiments of this application provide a communication method that can be applied to a second device. The second device can be a terminal or access network device, or a component of a terminal or access network device (e.g., a module, communication module, circuit or chip responsible for communication and / or sensing functions (such as a modem chip, or a SoC chip or SIP chip containing a modem core), chip system, or processor), or a logical node, logical module, or software capable of implementing all or part of the functions of a terminal or access network device. For ease of description, the following description uses a second device as an example. The method may include: the second device receiving first information, the first information indicating K configurations, each configuration including frequency band information and period information, where K is an integer greater than or equal to 2; the second device receiving sensing signals according to the frequency band information and period information in each configuration.

[0012] Using this method, the first information can be used to configure resources for transmitting sensing signals; correspondingly, the second device can accurately determine the resources for transmitting sensing signals based on the first information. Furthermore, in this method, the second device can receive sensing signals based on frequency band information and periodic information from multiple configurations, thereby expanding the unambiguous range of speed measurement and reducing the overhead of sensing time-domain resources.

[0013] Thirdly, embodiments of this application provide a communication method that can be applied to a third device. The third device can be a sensing management function or a device containing a sensing management function. The device containing a sensing management function can be a terminal or access network device, or a module, communication module, circuit or chip (such as a modem chip, or a SoC chip or SIP chip containing a modem core), chip system, or processor within the terminal or access network device. It can also be a logical node, logical module, or software capable of implementing all or part of the functions of the terminal or access network device, or a device independent of the terminal or access network device. For ease of description, the following explanation uses a third device as an example. The method may include: the third device determining first information, the first information indicating K configurations, each configuration including frequency band information and period information, where K is an integer greater than or equal to 2. The third device then sends the first information.

[0014] This method allows for the configuration of resources for transmitting sensing signals. Furthermore, the third device can be configured with multiple configurations, enabling the sensing signal transmitting device to transmit the sensing signal based on frequency band and periodic information from these configurations. This expands the unambiguous range of speed measurement and reduces the overhead of sensing time-domain resources.

[0015] Based on any one of the first to third aspects, in one possible design, the K configurations include a first configuration and a second configuration, wherein the first configuration and the second configuration satisfy one of the following:

[0016] 1. The frequency band information in the first configuration is the same as that in the second configuration, but the period information in the first configuration is different from that in the second configuration. Since the frequency band information in the first configuration is the same as that in the second configuration, frequency domain resources used for transmitting sensing signals can be saved, and the overhead of indicating frequency band information can be reduced.

[0017] 2. The frequency band information in the first configuration is different from that in the second configuration, but the period information in the first configuration is the same as that in the second configuration. Because the period information in the first configuration is the same as that in the second configuration, the overhead of indicating period information can be reduced.

[0018] 3. The frequency band information in the first configuration is different from that in the second configuration, and the period information in the first configuration is also different from that in the second configuration.

[0019] In this design, the frequency band information in the first configuration is different from that in the second configuration, and / or the period information in the first configuration is different from that in the second configuration. This makes the maximum unambiguous speeds corresponding to the first configuration and the second configuration different, thereby expanding the unambiguous speed measurement range corresponding to the first configuration and the second configuration and reducing the overhead of sensing resources.

[0020] Based on any one of the first to third aspects, in one possible design, the first information indicates the number of time units corresponding to the periodic information in each of the K configurations. With this design, the device receiving the first information (e.g., the first device and / or the second device) can accurately determine the period indicated by the periodic information in each configuration based on the number of time units corresponding to the periodic information in each of the K configurations.

[0021] Based on any one of the first to third aspects, in one possible design, the first information further indicates the length of the time unit corresponding to the periodic information in each of the K configurations. With this design, the device receiving the first information (e.g., the first device and / or the second device) can accurately determine the length of the time unit corresponding to the periodic information in each of the K configurations based on the first information. Furthermore, in this design, the length of the time unit can be indicated by the third device, thus allowing the third device to flexibly configure resources for time units of various lengths.

[0022] Based on the first or third aspect, in one possible design, the method further includes: a first device sending first frequency band indication information; and correspondingly, a third device receiving the first frequency band indication information. The first frequency band indication information indicates L1 frequency bands supported by the first device, where L1 is a positive integer, and the L1 frequency bands include K frequency bands indicated by configured frequency band information. The first device may be a first device or a device in which the first device is located. Through this design, the first device can indicate the L1 frequency bands supported by the first device to the third device. Thus, the third device can configure sensing resources for the first device that are adapted to the capabilities of the first device; for example, it can configure sensing resources for the frequency bands supported by the first device, thereby improving sensing performance.

[0023] Based on the second or third aspect, in one possible design, the method further includes: the second device sending second frequency band indication information; and correspondingly, the third device receiving the second frequency band indication information. The second frequency band indication information indicates L2 frequency bands supported by the second device, where L2 is a positive integer, and the L2 frequency bands include K frequency bands indicated by the configured frequency band information. The second device may be a second device itself, or a device in which the second device resides. Through this design, the second device can indicate the L2 frequency bands supported by the second device to the third device. Thus, the third device can configure sensing resources adapted to the capabilities of the second device for the second device; for example, it can configure sensing resources for the frequency bands supported by the second device, thereby improving sensing performance.

[0024] Based on the first or third aspect, in one possible design, the method further includes: a first device sending second information; and correspondingly, a third device receiving the second information. The second information indicates the value of K. With this design, the third device can accurately determine the value of K based on the second information.

[0025] Based on the second or third aspect, in one possible design, the third device further includes: the second device sending third information; and correspondingly, the third device receiving the third information. The third information indicates the value of K. With this design, the third device can accurately determine the value of K based on the third information.

[0026] Based on any one of the first to third aspects, in one possible design, given that the frequency band information in the K configurations is determined, the periodic information in the K configurations maximizes the least common multiple of the K values. The K values ​​are one of the following: the maximum unambiguous velocity corresponding to each of the K configurations, the quantized value of the maximum unambiguous velocity corresponding to each of the K configurations, or a value obtained based on the quantized value of the maximum unambiguous velocity corresponding to each of the K configurations. Since the maximum velocity of the velocity measurement range corresponding to the K configurations is positively correlated with the least common multiple of the K values, this design maximizes the velocity measurement range corresponding to the K configurations, thereby expanding the unambiguous velocity measurement range and reducing the overhead of sensing time-domain resources.

[0027] Based on any one of the first to third aspects, in one possible design, given that the frequency band information in the K configurations is determined, the periodic information in the K configurations ensures that the least common multiple of the K values ​​is greater than a first threshold. Since the maximum speed of the speed measurement range corresponding to the K configurations is positively correlated with the least common multiple of the K values, this design allows the speed measurement range corresponding to the K configurations to meet the threshold requirement, thereby expanding the unambiguous speed measurement range and reducing the overhead of sensing time-domain resources.

[0028] Based on any one of the first to third aspects, in one possible design, the K values ​​are values ​​obtained from the quantization value of the maximum unambiguous speed corresponding to each of the K configurations, including:

[0029] The i-th value among K values Satisfy the following formula:

[0030] Where i takes integers from 1 to K. Let be the quantized value of the maximum unambiguous speed corresponding to the i-th configuration among the K configurations. Includes k decimal places, where k is a positive integer.

[0031] This design allows for the accurate determination of the quantized value obtained based on the maximum unambiguous speed corresponding to each of the K configurations.

[0032] Based on any one of the first to third aspects, in one possible design, the K configurations include a first configuration and a second configuration, wherein the first configuration and the second configuration satisfy at least one of the following: the difference between the maximum unambiguous speed corresponding to the first configuration and the maximum unambiguous speed corresponding to the second configuration is greater than a second threshold; the difference between the first quantization value and the second quantization value is greater than a third threshold, wherein the first quantization value is the quantized value of the maximum unambiguous speed corresponding to the first configuration, and the second quantization value is the quantized value of the maximum unambiguous speed corresponding to the second configuration; or, the difference between the value obtained according to the first quantization value and the value obtained according to the second quantization value is greater than a fourth threshold. Through this design, the third device can select the first configuration and the second configuration that satisfy the threshold requirements.

[0033] Based on the first or third aspect, in one possible design, the method further includes: a first device sending first threshold information; and correspondingly, a third device receiving the first threshold information. The first threshold information indicates a first threshold. With this design, the third device can accurately determine the first threshold based on the first threshold information.

[0034] Based on the second or third aspect, in one possible design, the method further includes: a second device sending second threshold information; correspondingly, a third device receiving third information, wherein the second threshold information indicates the first threshold. With this design, the third device can accurately determine the first threshold based on the second threshold information.

[0035] Based on any one of the first to third aspects, in one possible design, and The integers are coprime. Here, i and j are integers greater than or equal to 1 and less than or equal to K, and i and j are distinct. This is the value obtained from the quantization of the maximum unambiguous speed corresponding to the i-th configuration among the K configurations. This is the value obtained by quantizing the maximum unambiguous speed corresponding to the j-th configuration among the K configurations. Since the maximum speed within the speed measurement range corresponding to the K configurations is... Positive correlation, LCM stands for least common multiple operation. Therefore, this design can make the speed measurement range corresponding to K configurations as large as possible, thereby expanding the range of unambiguous speed measurement and reducing the overhead of sensing time domain resources.

[0036] Fourthly, embodiments of this application provide a communication method that can be applied to a third device. The third device can be a sensing management function or a device containing a sensing management function. A device containing a sensing management function can be a terminal or access network device, or a module, communication module, circuit or chip (such as a modem chip, or a SoC chip or SIP chip containing a modem core), chip system, or processor within the terminal or access network device. It can also be a logic node, logic module, or software capable of implementing all or part of the functions of the terminal or access network device, or a device independent of the terminal or access network device. For ease of description, the following explanation uses a third device as an example.

[0037] Through this method, the third device can update the resources used for transmitting sensing signals in a timely manner. Furthermore, in this method, the first device can output sensing signals based on first frequency band information and first period information, and also based on second frequency band information and second period information, thereby expanding the unambiguous range of speed measurement and reducing the overhead of sensing time-domain resources.

[0038] Fifthly, embodiments of this application provide a communication method that can be applied to a first device. The first device can be a terminal or access network device, or a device of the terminal or access network device (e.g., a module, communication module, circuit or chip responsible for communication and / or sensing functions (such as a modem chip, or a SoC chip or SIP chip containing a modem core), chip system, or processor), or a logical node, logical module, or software capable of implementing all or part of the functions of the terminal or access network device. For ease of description, the following description uses the first device as an example. The method may include: the first device receiving fourth information, the fourth information indicating first frequency band information and first periodic information; the first device outputting M1 sensing signals according to the first frequency band information and the first periodic information, where M1 is a positive integer; under a first condition, the first device receiving fifth information, the fifth information indicating second frequency band information and second periodic information; the first device outputting M2 sensing signals according to the second frequency band information and the second periodic information, where M2 is a positive integer.

[0039] Through this method, the third device can update the resources used for transmitting sensing signals in a timely manner. Furthermore, in this method, the first device can output sensing signals based on first frequency band information and first period information, and also based on second frequency band information and second period information, thereby expanding the unambiguous range of speed measurement and reducing the overhead of sensing time-domain resources.

[0040] Sixthly, embodiments of this application provide a communication method that can be applied to a second device. The second device can be a terminal or access network device, or a device of the terminal or access network device (e.g., a module, communication module, circuit or chip responsible for communication and / or sensing functions (such as a modem chip, or a SoC chip or SIP chip containing a modem core), chip system, or processor), or a logical node, logical module, or software capable of implementing all or part of the functions of the terminal or access network device. For ease of description, the following description uses a second device as an example. The method may include: the second device receiving fourth information, the fourth information indicating first frequency band information and first periodic information; the second device receiving M1 sensing signals according to the first frequency band information and the first periodic information, where M1 is a positive integer; under a first condition, the second device receiving fifth information, the fifth information indicating second frequency band information and second periodic information; the second device receiving M2 sensing signals according to the second frequency band information and the second periodic information, where M2 is a positive integer.

[0041] Through this method, the third device can update the resources used for transmitting sensing signals in a timely manner. Furthermore, in this method, the second device can receive sensing signals based on first frequency band information and first period information, and also based on second frequency band information and second period information, thereby expanding the unambiguous range of speed measurement and reducing the overhead of sensing time-domain resources.

[0042] Based on any one of aspects four through six, in one possible design, the first condition includes at least one of the following:

[0043] 1. The absolute value of the actual velocity of the sensed target is greater than the maximum unambiguous velocity corresponding to the first frequency band information and the first periodic information. Thus, when the actual velocity of the sensed target cannot be accurately measured using the first frequency band information and the first periodic information, the third device can be configured with second frequency band information and second periodic information, thereby expanding the unambiguous range of velocity measurement and improving the accuracy of velocity measurement of the sensed target.

[0044] 2. Insufficient resources corresponding to the first frequency band information and the first periodic information. Therefore, when resources corresponding to the first frequency band information and the first periodic information are insufficient, the third device can allocate more resources using the second frequency band information and the second periodic information, thereby improving sensing performance.

[0045] 3. There is a surplus of resources corresponding to the first frequency band information and the first cycle information. In this case, with a surplus of resources corresponding to the first frequency band information and the first cycle information, the third device can allocate fewer resources through the second frequency band information and the second cycle information, thereby reducing or avoiding resource waste and improving resource utilization.

[0046] 4. The third device receives a first request, which requests a change in the configuration of the sensing resources. Optionally, the first request may be sent by the first device and / or the second device. In this way, the third device can update the configuration of the sensing resources in a timely manner based on the first request.

Here, || represents the maximum unambiguous velocity corresponding to the first frequency band information and the first period information, and || denotes the absolute value operation. Through this design, the third device can accurately determine whether the absolute value of the actual velocity of the sensed target is greater than the maximum unambiguous velocity corresponding to the first frequency band information and the first period information, thereby enabling timely updates to the configuration of sensing resources and reducing or avoiding velocity measurement ambiguity.

[0049] Based on any one of aspects four through six, in one possible design, the first frequency band information and the second frequency band information are the same, while the first periodic information and the second periodic information are different; or, the first frequency band information and the second frequency band information are different, while the first periodic information and the second periodic information are the same; or, the first frequency band information and the second frequency band information are different, while the first periodic information and the second periodic information are different. In this design, the first frequency band information and the second frequency band information are different, and / or the first periodic information and the second periodic information are different, thereby making the maximum unambiguous velocities corresponding to the fourth information and the fifth information different, which can expand the unambiguous range of velocity measurement corresponding to the fourth information and the fifth information and reduce the overhead of sensing resources.

[0090] The technical solutions in the embodiments of this application will be described below with reference to the accompanying drawings. The technical solutions in the embodiments of this application can be applied to various communication systems, such as wireless local area networks (WLANs), wireless fidelity (Wi-Fi or WiFi) systems, fourth-generation (4G) mobile communication systems (such as long-term evolution (LTE) systems), fifth-generation (5G) mobile communication systems (such as new radio (NR) systems), or future communication systems. The methods provided in the embodiments of this application can be applied to terrestrial network communication systems or non-terrestrial network (NTN) communication systems. NTN communication systems can be, for example, satellite communication systems, and may also include unmanned aerial vehicles (UAVs), high-altitude platform stations (HAPS), and other aerial access network equipment; this application does not limit these aspects.

[0091] This application will present various aspects, embodiments, or features relating to systems that may include multiple devices, components, modules, etc. It should be understood and appreciated that individual systems may include additional devices, components, modules, etc., and / or may not include all the devices, components, modules, etc. discussed in conjunction with the accompanying drawings. Furthermore, combinations of these approaches are also possible.

[0092] Figure 1 illustrates a schematic diagram of a communication system provided in an embodiment of this application. As shown in Figure 1, the communication system includes a radio access network (RAN) 100 and a core network (CN) 200. Optionally, the communication system may also include the Internet 300.

[0093] RAN 100 includes at least one RAN node (110a and 110b in Figure 1, collectively referred to as 110) and at least one terminal (120a-120j in Figure 1, collectively referred to as 120). RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment (not shown in Figure 1). Terminal 120 is wirelessly connected to RAN node 110. RAN node 110 is wirelessly or wired connected to core network 200. The core network equipment in core network 200 and RAN node 110 in RAN 100 can be different physical devices, or they can be the same physical device integrating core network logical functions and wireless access network logical functions.

[0094] RAN 100 can be a cellular system related to the 3rd Generation Partnership Project (3GPP), such as 4G, 5G mobile communication systems, or future-oriented evolution systems. RAN 100 can also be an open RAN (ORAN or O-RAN), a cloud radio access network (CRAN), or a WiFi system. RAN 100 can also be a communication system that integrates two or more of the above systems.

[0095] RAN node 110, sometimes referred to as RAN entity or access node, constitutes part of the communication system and assists terminals in achieving wireless access. Multiple RAN nodes 110 in the communication system can be of the same type or different types. In some scenarios, the roles of RAN node 110 and terminal 120 are relative. For example, network element 120i in Figure 1 can be a helicopter or drone, which can be configured as a mobile base station. For terminals 120j accessing RAN 100 through network element 120i, network element 120i is a base station; however, for base station 110a, network element 120i is a terminal. RAN node 110 and terminal 120 are sometimes both referred to as communication devices. For example, network elements 110a and 110b in Figure 1 can be understood as communication devices with base station functions, and network elements 120a-120j can be understood as communication devices with terminal functions.

[0096] RAN nodes can also be described in different ways, such as access network equipment. Unless otherwise specified in this application, access network equipment will be used as the term.

[0097] Access network equipment can be devices or modules located on the network side of the aforementioned communication system and possessing corresponding communication functions. Access network equipment typically contains communication modules, circuits, or chips that perform the corresponding communication functions. Access network equipment may also be configured with programs or instructions for performing the corresponding communication functions, as well as the corresponding programs or instructions themselves.

[0098] In one possible scenario, access network equipment can be a base station (BS), an evolved NodeB (eNodeB), a transmission point (TP), an access point (AP), a transmission reception point (or transmit / receive point, TRP), a mobile switching center, a next-generation NodeB (gNB), a next-generation base station in a future communication system, or an access node in a WiFi system. Access network equipment can also be a macro base station (as shown in Figure 1, 110a), a micro base station or indoor station (as shown in Figure 1, 110b), a relay node or donor node, a radio controller in a CRAN scenario, a satellite, a drone, a balloon, or an aircraft. Optionally, access network equipment can also be a server, wearable device, vehicle, or in-vehicle equipment. For example, in vehicle-to-everything (V2X) technology, the access network equipment can be a roadside unit (RSU). All or part of the functions of the access network device in this application can also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (e.g., a cloud platform).

[0099] In another possible scenario, multiple access network devices collaborate to assist the terminal in achieving wireless access, with each device performing a portion of the base station's functions. For example, the access network devices can be a central unit (CU or control unit), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and DU can be separate entities or included in the same network element, such as a baseband unit (BBU). The RU can be included in radio frequency equipment or radio frequency units, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0100] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called an open CU (O-CU), DU can also be called an open DU (O-DU), CU-CP can also be called an open CU-CP (O-CU-CP), CU-UP can also be called an open CU-UP (O-CU-UP), and RU can also be called an open RU (O-RU). Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules.

[0101] For ease of description, the concepts of "access network equipment" and "site" will be used together in this application. Access network equipment can be understood as a collective term for all equipment (including sites) on the access network side; for example, one or more sites can be collectively referred to as access network equipment. A site can refer to a transmission node specifically located in a physical location. In other words, access network equipment conceptually includes sites.

[0102] A terminal is a device or module that connects to the aforementioned communication system and possesses corresponding communication functions. A terminal can also be called a terminal device, user equipment (UE), mobile station, mobile terminal, wireless terminal device, subscriber unit, subscriber station, mobile station, remote station, user terminal, user agent, or user device, etc. A terminal typically contains communication modules, circuits, or chips that perform the corresponding communication functions. The terminal may also be configured with programs or instructions for performing these communication functions.

[0103] Terminals can be widely used in various scenarios, such as device-to-device (D2D), V2X communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, and smart cities. Terminals can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, vehicles, drones, helicopters, airplanes, ships, robots, robotic arms, smart home devices, etc. 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. Terminals used in vehicles are called in-vehicle terminal devices, which include, for example, transportation vehicles with wireless communication capabilities, communication modules, or on-board units (OBUs).

[0104] For example, a terminal may include a mobile phone (or "cellular" phone), a computer with a mobile terminal device, or a portable, pocket-sized, handheld, or computer-embedded mobile device. For instance, a terminal may be a Personal Communication Service (PCS) phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), or other similar devices. A terminal may also include restricted devices, such as devices with limited power consumption, limited storage capacity, or limited computing power. For example, a terminal may be an information sensing device such as a barcode scanner, radio frequency identification (RFID), a sensor, a global positioning system (GPS), or a laser scanner. The embodiments of this application do not limit the device form of the terminal.

[0105] In this application, core network equipment refers to equipment in the core network that provides service support to terminals. For example, in the case where CN200 is the core network of a future communication system, a 5G core network, or an evolved 5G core network, some examples of core network equipment include: access and mobility management function (AMF) entities, session management function (SMF) entities, user plane function (UPF) entities, policy control function (PCF) entities, etc., which are not listed here. Among them, the AMF entity can be responsible for terminal access management and mobility management; the SMF entity can be responsible for session management, such as user session establishment; the UPF entity can be a user plane functional entity, mainly responsible for connecting to external networks. For example, in the case of CN200 as the 4G core network, some core network devices include: Mobility Management Entity (MME), Home Subscriber Server (HSS), Serving Gateway (S-GW), Policy and Charging Rules Function (PCRF), Public Data Network Gateway (PDN Gateway, P-GW), etc., which will not be listed here. It should be noted that in this application, entities can also be referred to as network elements or functional entities. For example, an AMF entity can also be called an AMF network element or AMF functional entity, and similarly, an SMF entity can also be called an SMF network element or SMF functional entity. The aforementioned core network devices can operate independently or be combined to implement certain control functions. For example, AMF, SMF, and PCF can be combined into a single core network device.

[0106] 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.

[0107] The relevant terms used in the embodiments of this application will be explained below. It should be noted that these explanations are for the purpose of making the embodiments of this application easier to understand, and should not be regarded as a limitation on the scope of protection claimed by this application.

[0108] 1) Integrated communication and sensing:

[0109] Integrated communication and sensing technology is considered one of the key technologies for expanding the service capabilities of mobile communication networks. The core idea of ​​this technology is to add sensing capabilities to the mobile communication network, building capabilities such as target detection, tracking, and imaging, thereby integrating communication and sensing capabilities into a single network to achieve harmonious coexistence and mutual benefit. Please refer to Figure 2, which is a schematic diagram of an integrated communication and sensing scenario. In Figure 2, solid lines represent communication, and dashed lines represent sensing, illustrating an example. As shown in Figure 2, access network devices can sense other objects through self-transmission and reception, or they can sense other objects while communicating with the terminal. Figure 2 illustrates an example where the terminal is a smartphone, and the sensed targets are drones, pedestrians, and vehicles.

[0110] Sensing technology can generally be divided into two modes: mono-static sensing and bi-static sensing. Mono-static sensing refers to a single device that transmits the sensing signal and receives the echo signal. In other words, in mono-static sensing, the transmitting device both transmits the sensing signal and receives the echo signal obtained after the sensing signal interacts with the surface of the sensing target (e.g., reflection, diffraction, or scattering). Therefore, this mono-static sensing mode can also be called a self-transmitting and self-receiving mode, without limitation. Bi-static sensing refers to two different devices that transmit the sensing signal and receive the echo signal. In other words, sensing station A transmits the sensing signal, and the echo signal obtained after the sensing signal interacts with the surface of the sensing target is received by sensing station B. Therefore, this bi-static sensing mode can also be called the A-transmitting and B-receiving mode. It should be noted that the echo signal is obtained after the sensing signal interacts with the sensing target (e.g., reflection, diffraction, or scattering), therefore, this echo signal can still be called the sensing signal.

[0111] Figure 3 illustrates a schematic diagram of the sensing scenarios applicable to the embodiments of this application. Figure 3 provides eight sensing scenarios applicable to the embodiments of this application, namely: the scenario where access network device A transmits and receives signals independently, i.e., the scenario where access network device A sends sensing signals and receives echo signals, as shown in (1) of Figure 3; the scenario where terminal A transmits and receives signals independently, i.e., the scenario where terminal A sends sensing signals and receives echo signals, as shown in (2) of Figure 3; the scenario where access network device A sends sensing signals and access network device B receives echo signals, as shown in (3) of Figure 3; and the scenario where terminal A sends sensing signals and terminal B receives echo signals, as shown in (4) of Figure 3. Figure 3 shows (4); the scenario where access network device A sends a sensing signal and terminal A receives an echo signal is shown in Figure 3 (5); the scenario where terminal A sends a sensing signal and access network device A receives an echo signal is shown in Figure 3 (6); the scenario where access network device A sends a sensing signal and access network device B receives an echo signal under the control of access network device C is shown in Figure 3 (7); the scenario where terminal A sends a sensing signal and terminal B receives an echo signal under the control of access network device A is shown in Figure 3 (8). Figure 3 uses a vehicle as the sensing target and a smartphone as the terminal as an example.

[0112] Optionally, in the sensing scenario applicable to the embodiments of this application, there may be one or more transmitting devices for transmitting sensing signals, and one or more receiving devices for receiving echo signals of the sensing signals. Figure 3 illustrates an example with one transmitting device and one receiving device, but is not intended to be limiting.

[0113] When there are multiple transmitting devices and one receiving device, the sensing scenario can be called a multi-transmitter, single-receiver scenario. For example, sensing station A and sensing node C each transmit sensing signals, and the echo signal obtained by the sensing signals passing through the surface of the sensing target is received by sensing station B. Another example is that sensing station A and sensing node B each transmit sensing signals, and the echo signal obtained by the sensing signals passing through the surface of the sensing target is received by sensing station B.

[0114] When there is one transmitting device and multiple receiving devices, this scenario can be called a one-to-many scenario. For example, sensing station A transmits a sensing signal, and the echo signal obtained by the sensing signal passing through the surface of the sensing target is received by sensing station B and sensing node C. Another example is that sensing station A transmits a sensing signal, and the echo signal obtained by the sensing signal passing through the surface of the sensing target is received by sensing station A and sensing node B.

[0115] The sensing target can also be referred to as a target, a detected target, a sensed object, a sensed device, etc., without limitation. The sensing target can be any tangible object in the environment capable of reflecting, diffracting, or scattering electromagnetic waves. For example, the sensing target can be a stationary object such as a mountain, forest, or building. Alternatively, the sensing target can be a mobile object such as a vehicle, drone, pedestrian, or terminal. This application does not limit the specific implementation form of the sensing target.

[0116] The sensing result can also be referred to as the detected result, the detected data, or the detected data, etc., without limitation. The sensing result can be the result obtained by the receiving device processing the echo signal. For example, the sensing result may include at least one of the following: the position of the sensed target, the velocity of the sensed target, the distance from the sensed target to the receiving device, the distance from the sensed target to the transmitting device, the direction or angle of the sensed target, or the intensity of the echo signal, etc.

[0117] 2) Sensing signals:

[0118] In this application, the sensing signal may include a reference signal and / or a communication signal other than a reference signal.

[0119] The reference signal, also known as the pilot signal, is essential in communication systems for transmitting and receiving data, obtaining system synchronization and feedback channel information, and estimating the uplink or downlink channel. Channel estimation refers to the process of reconstructing or recovering the received signal to compensate for signal distortion caused by channel fading and noise fading. It uses known reference signals from the transmitter and receiver to determine the time and frequency domain variations of the channel. These reference signals, also called reference signals, are distributed across one or more resource elements (REs) in the time-frequency two-dimensional space within orthogonal frequency division multiplexing (OFDM) symbols, and have known amplitude and phase.

[0120] For example, the reference signal may include an uplink reference signal and a downlink reference signal. The uplink reference signal may include, but is not limited to, at least one of the following: a sounding reference signal (SRS), an uplink demodulation reference signal (DMRS), an uplink phase noise tracking reference signal (PTRS), or an uplink positioning signal (CRS). The downlink reference signal may include, but is not limited to, at least one of the following: downlink DMRS, PTRS, a channel status information reference signal (CSI-RS), a positioning reference signal (PRS), or a cell reference signal (CRS).

[0121] It should be understood that the reference signals listed above are merely examples and should not be construed as limiting this application. This application does not preclude the possibility of defining other reference signals in future agreements to achieve the same or similar functions.

[0122] 3) Frequency band:

[0123] A frequency band can also be called an operating band, frequency range, or working frequency band. 3GPP can divide the entire wireless spectrum into multiple frequency bands according to certain rules, and each frequency band can correspond to a certain frequency range (or spectrum range). Table 1 gives examples of several frequency band divisions under frequency range 1 (FR 1).

[0124] Table 1

[0125] In this application, a frequency band can be replaced with (or can be understood as) a frequency within a frequency band, for example, the center frequency of the frequency band.

[0126] 4) Speed ​​Measurement by Sensing:

[0127] As shown in Figure 4A, the sensing signal can be uniformly distributed (or placed) on a single-frequency band resource. The period T and frequency band f of the sensing signal together determine the speed measurement range, which will be explained below.

[0128] For a period T, the corresponding maximum Doppler frequency shift It is related to formula (1), or determined according to formula (1), or satisfies formula (1):

[0129] That is, the Doppler frequency shift range corresponding to period T is

[0130] The relationship between the Doppler frequency shift and the relative velocity of the target is shown in Equation (2), or the Doppler frequency shift and the relative velocity of the target satisfy Equation (2): v = λf d (2)

[0131] Where v is the relative velocity of the target being sensed, λ is the wavelength corresponding to frequency band f, and f d This is the Doppler frequency shift.

[0132] Therefore, the maximum relative velocity v corresponding to the period T and frequency band f max Formula (3) can be satisfied:

[0133] As shown in Figure 4B, the relative velocity v of the perceived target also satisfies formula (4):

[0134] Where d is the differential symbol (or differential operator), R tx R is the distance between the transmitting (TX) device and the sensing target. rx Let dt be the distance between the receiving (RX) device and the sensing target, and let dt be an infinitesimal time interval, i.e., the change in time. When the TX and RX devices are in different spatial locations, the sensing mode can be a bistatic sensing mode; when the TX and RX devices are in the same spatial location, the sensing mode can be a monostatic sensing mode.

[0135] The relationship between the actual velocity of the perceived target and the relative velocity of the perceived target is shown in formula (5), or the actual velocity of the perceived target and the relative velocity of the perceived target satisfy formula (5): v = k1v physical (5)

[0136] Where k1 is a coefficient, and k1 can be related to at least one of the following: the relative positions of the TX device, the sensing target, and the RX device; and the direction of motion of the sensing target. k1 can be greater than or equal to 1 and less than or equal to 2. physical To perceive the actual speed of the target.

[0137] Therefore, the maximum actual speed corresponding to the period T and frequency band f Satisfies formula (6):

[0138] That is, the speed measurement range corresponding to the period T and frequency band f can be:

[0139] If the actual speed of the sensed target falls within the speed measurement range, or in other words, if the absolute value of the actual speed of the sensed target is less than or equal to... By using a sensing signal with a period of T and a frequency band of f, the actual speed of the target can be accurately determined. For example, if the actual speed of the target is 20 meters per second (m / s), the period T and frequency band f correspond to... With a speed of 30 m / s, the actual speed of the target can be accurately determined by a sensing signal with a period of T and a frequency band of f.

[0140] If the actual speed of the sensed target is not within the speed measurement range, or in other words, if the absolute value of the actual speed of the sensed target is greater than... Measuring the actual velocity of the target using a sensing signal with period T and frequency band f will result in ranging ambiguity (or ranging error). The velocity of the target will be perceived as v. ′ v ′ Satisfies formula (7):

[0141] Here, mod() represents the modulo operation. For v physical Divide by The remainder; v physical To perceive the actual speed of the target. ′ belong

[0142] For example, when the actual speed of the perceived target is 30 m / s, the period T and the corresponding frequency band f are... With a speed of 20 m / s, the velocity of the target is measured to be 10 m / s using a sensing signal with period T and frequency band f.

[0143] Ranging ambiguity is related to the velocity measurement range. Influenced by the maximum value of the velocity measurement range, the perceived target will exhibit periodic extensions in the velocity dimension; in other words, the perceived target will appear periodically in the velocity dimension. For example, Figure 4C shows a possible RV map corresponding to the period T and frequency band f. As shown in Figure 4C, each box could be the location of the perceived target #1, and the velocity corresponding to each box could be the actual velocity of the perceived target #1. Therefore, when the absolute value of the actual velocity of the perceived target #1 is greater than... At that time, the speed of the target cannot be determined by the sensing signal with period T and frequency band f, which will result in ranging ambiguity.

[0144] In this application, the period of the sensing signal may be replaced by (or can be understood as) at least one of the following: the transmission period of the sensing signal, the transmission period of the sensing signal, or the period of the resources used to transmit (or carry) the sensing signal.

[0145] The frequency band of the sensing signal can be replaced (or can be understood as) at least one of the following: the operating frequency band of the sensing signal, or the frequency band of the resources used to transmit (or carry) the sensing signal.

[0146] The maximum actual speed corresponding to period T and frequency band f It can be replaced (or understood as) at least one of the following: the maximum unambiguous velocity corresponding to the period T and the frequency band f; or, the maximum velocity that can be measured by a sensing signal with a period of T and a frequency band of f.

[0147] 5) Time unit:

[0148] A time unit can be a unit of time-domain resources. For example, a time unit can include at least one of the following: a system frame, a subframe, a slot, or a symbol. A symbol can be a time-domain symbol (e.g., an orthogonal frequency division multiplexing (OFDM) symbol).

[0149] 6) In this application, "instruction" or "for instruction" may include explicit instruction (or direct instruction) and implicit instruction (or indirect instruction). When describing information for instructing A, it may include whether the information explicitly instructs A or implicitly instructs A, but does not necessarily mean that the information carries A.

[0150] The indication methods involved in the embodiments of this application should be understood to cover various methods that enable the party to be indicated to obtain the information to be indicated. The information to be indicated can be sent as a whole or divided into multiple sub-information and sent separately. Moreover, the sending period and / or sending time of these sub-information can be the same or different, without limitation.

[0151] In the embodiments of this application, "information" can be an explicit indication, that is, a direct indication through signaling, or obtained by combining other rules or parameters with parameters indicated by signaling, or by deduction. It can also be an implicit indication, that is, obtained based on rules or relationships, or based on other parameters, or by deduction. No limitation is imposed.

[0152] 7) In this application, communication between different devices can refer to direct communication between different devices (i.e., without the need for relaying or forwarding by other devices), or communication between different devices through other devices (i.e., requiring relaying or forwarding by other devices), or communication between a functional unit within a device and other devices through another functional unit. For example, "sending information to…(terminal)" can be understood as the destination of the information being the terminal, and may include sending information directly or indirectly to the terminal. "Receiving information from…(terminal)" can be understood as the source of the information being the terminal, and may include receiving information directly or indirectly from the terminal. Information may undergo necessary processing between the source and destination of information transmission, such as format changes, digital-to-analog conversion, amplification, filtering, etc., but the destination can understand the valid information from the source. Similar expressions in this application can be understood in a similar way, and will not be elaborated further here.

[0153] 8) In this application, the words “exemplarily,” “for example,” “e.g.,” and “example” are used to indicate examples, illustrations, or descriptions, and are not intended to limit the scope of protection of this application. It should be understood that the examples in this application may also be implemented in other ways.

[0154] 9) In this application, any two of the program, instructions and code may be substituted for each other.

[0155] 10) In this application, "greater than or equal to" and "greater than" are interchangeable. "less than or equal to" and "less than" are interchangeable. For example, A is less than B, which can be replaced with: A is less than or equal to B. Another example, A is greater than B, which can be replaced with: A is greater than or equal to B. Yet another example, A is less than B and greater than C, which can be replaced with: A is less than or equal to B and greater than C; or it can also be replaced with: A is less than or equal to B and greater than or equal to C; or it can also be replaced with: A is less than B and greater than or equal to C.

[0156] 11) In this application, “in the case of…”, “when…”, “if…”, and “if…” can have the same meaning and can be used interchangeably.

[0157] 12) In this application, “speed”, “movement speed” and “travel speed” may have the same meaning and may be used interchangeably.

[0158] 13) In this application, “coprime” and “coprime numbers” can have the same meaning and can be used interchangeably.

[0159] Sensing technology can be applied in the field of wireless communication. Further research is needed on how to configure resources for transmitting sensing signals within the wireless communication domain.

[0160] Currently, the perception management function can configure a perception node with a corresponding frequency band and a period of resources, which can be used to transmit perception signals. However, as mentioned earlier, when the absolute value of the actual speed of the perceived target is greater than the frequency band and period corresponding to... This can lead to ranging ambiguity. To reduce or avoid ranging ambiguity, this resource will consume more time-domain resources, resulting in higher time-domain resource overhead.

[0161] For example, the frequency band of the sensed signal is f c = 28 GHz (wavelength λ = 1.07 cm); the maximum speed of the target in the sensing scenario is 120 km / h (approximately 33.3 m / s); the subcarrier spacing (SCS) corresponding to the sensing signal is 30 kHz, and correspondingly, the length of one symbol is approximately 0.5 / 14 = 0.0357 ms. When the sensing scenario is as shown in Figure 4D, the value of k1 can be close to 2, and correspondingly, To avoid ranging ambiguity, The speed should be greater than or equal to 33.3 m / s, and correspondingly, the period T should be less than or equal to 0.08 ms. Since the length of a symbol is 0.0357 ms, the period T should be 1 or 2 symbols; in other words, at least one of every two symbols should be used for sensing, and the overhead of sensing time-domain resources should be at least 50%, otherwise the overhead of sensing time-domain resources will be too large.

[0162] Further research is needed on how to reduce the overhead of sensing time-domain resources.

In this arrangement, steps other than transmitting sensing signals between the first device and the second device are optional.

[0171] This application provides a communication method. Figure 5 is a flowchart illustrating the communication method provided in this application. As shown in Figure 5, the method includes:

[0172] S501: The third device sends the first information; correspondingly, the first device receives the first information.

[0173] The first information may indicate K configurations, where K is an integer greater than or equal to 2, for example, K is 2, 3, 4, or 5. Each of the K configurations may include frequency band information and period information. Optionally, the frequency band information in each configuration may indicate the frequency band of the resource corresponding to that configuration, and the period information in each configuration may indicate the period of the resource corresponding to that configuration; or, the frequency band information and period information in each configuration may be used to determine the resource corresponding to that configuration. For example, the frequency band information in the i-th configuration of the K configurations indicates frequency band #i, and the period information in the i-th configuration indicates period #i. Frequency band #i and period i are the frequency band and period of the resource corresponding to the i-th configuration, respectively. i takes integers from 1 to K. The resource corresponding to the configuration may be replaced with the resource indicated (or configured) by the configuration.

[0174] The specific contents of the K configurations and the first information indicating the K configurations will be explained below and will not be elaborated here.

[0175] The first information can be carried in a traditional message or in a new message. For example, the first information can be carried in a radio resource control (RRC) message, a medium access control-control element (MAC CE) message, or downlink control information (DCI).

[0176] S502: The third device sends the first information; correspondingly, the second device receives the first information.

[0177] For details of S502, please refer to S501, except that the first device is replaced by the second device, which will not be repeated here.

[0178] In some possible ways, the first information may be information broadcast by the third device. In this case, S501 and S502 can be combined into: the third device can send the first information; correspondingly, the first device can receive the first information, and the second device can receive the first information.

[0179] In other possible configurations, the first information may be unicast by the third device. In this case, the third device may send the first information to both the first and second devices. The order in which the third device sends the first information to the first and second devices is not limited, that is, the order of S501 and S502 is not limited.

[0180] S503: The first device outputs a sensing signal based on the frequency band information and period information in each configuration; correspondingly, the second device receives the sensing signal based on the frequency band information and period information in each configuration.

[0181] The first device outputs a sensing signal based on the frequency band information and period information in each configuration, which can be replaced (or understood as) at least one of the following: the first device can output a sensing signal based on the resources corresponding to each configuration; or, for each configuration, the first device can output a sensing signal on the frequency band indicated by the frequency band information in the configuration and at the period indicated by the period information in the configuration.

[0182] The output sensing signal can be replaced by at least one of the following: generating a sensing signal; generating and outputting a sensing signal; sending a sensing signal; or generating and sending a sensing signal.

[0183] In some examples, the first device outputs a sensing signal, which may be achieved by the first device outputting (or transmitting) the sensing signal through an antenna. For example, the first device may be a base station or a device within a base station, and the first device outputs (or transmits) the sensing signal through the base station's antenna.

[0184] In other examples, the first device outputs a sensing signal, which may be through an interface between devices. For example, the first device is a CU or a device within a CU. The first device can output a sensing signal to the RU through an interface between the CU and the RU, and then the RU can output (or transmit) the sensing signal over the air interface.

[0185] The second device receives sensing signals based on the frequency band information and period information in each configuration, which can be replaced (or understood as) at least one of the following: the second device can receive sensing signals based on the resources corresponding to each configuration; or, for each configuration, the second device can receive sensing signals on the frequency band indicated by the frequency band information in the configuration, with the period indicated by the period information in the configuration.

[0186] The received sensing signal can be replaced with (or understood as): the echo signal of the received sensing signal.

[0187] For example, the K configurations include a first configuration and a second configuration. The resource corresponding to the first configuration is the sensing resource shown in (1) of Figure 6 (hereinafter referred to as resource #1); the resource corresponding to the second configuration is the sensing resource shown in (2) of Figure 6 (hereinafter referred to as resource #2). The first device can output a sensing signal through resource #1; correspondingly, the second device can receive a sensing signal through resource #1. The first device can output a sensing signal through resource #2; correspondingly, the second device can receive a sensing signal through resource #2.

[0188] Optionally, in S503, the first device can output a sensing signal based on the frequency band information and periodic information in each configuration (as shown in S503a in Figure 5). This sensing signal first reaches the sensing target via wireless transmission, and then reaches the second device after being affected by the sensing target (e.g., reflection, scattering, or diffraction), meaning the second device can receive the sensing signal (as shown in S503b in Figure 5). In other words, S503 can include S503a and S503b in Figure 5. It should be understood that the sensing signal can be transmitted from the first device to the second device through one or more transmission paths; only one is shown in the figure.

[0189] S504: The second device can sense based on the sensing signal.

[0190] Optionally, S504 can be replaced by at least one of the following: the second device processes the sensing signal; the second device processes the echo signal of the sensing signal; or the second device performs sensing based on the echo signal of the sensing signal.

[0191] The second device can perform sensing based on the sensing signal to obtain sensing results. The sensing results may include, for example, the position or velocity of the sensed target, without limitation. The specific details of the second device's measurement of the sensed target's velocity, depending on the configuration, can be found in the explanation of sensing velocity measurement in the terminology section above, and will not be repeated here.

[0192] Optionally, if the actual speed of the perceived target is greater than the absolute value of the maximum unambiguous speed corresponding to each of the K configurations, the second device can determine the actual speed of the perceived target based on multiple configurations among the K configurations. The following explanation uses the resources in Figure 6 as an example to illustrate this.

[0193] For example, the K configurations include a first configuration and a second configuration. The frequency band information in the first configuration indicates frequency band f1, the period information in the first configuration indicates period T1, and the resource corresponding to the first configuration can be the sensing resource shown in Figure 6(1) (hereinafter referred to as resource #1). The frequency band information in the second configuration indicates frequency band f2, the period information in the second configuration indicates period T2, and the resource corresponding to the second configuration can be the sensing resource shown in Figure 6(2) (hereinafter referred to as resource #2). The maximum unambiguous velocity corresponding to frequency band f1 and period T1 is... The maximum unambiguous speed corresponding to frequency band f2 and period T2 is

[0194] exist and Under different conditions, the true location of the perceived target will appear simultaneously in the RV maps corresponding to the first and second configurations, while targets at other locations are false targets caused by velocity ambiguity. For example, when measuring the perceived target #1 using the sensing signal carried by resource #1, as shown in Figure 7A, the locations of the boxes and circles could both be the locations of the perceived target #1, and the velocity corresponding to each box or circle could be the actual velocity of the perceived target #1. When measuring the perceived target #1 using the sensing signal carried by resource #2, as shown in Figure 7B, the locations of the boxes and circles could both be the locations of the perceived target #1, and the velocity corresponding to each box or circle could be the actual velocity of the perceived target #1. Combining Figures 7A and 7B, the location of the box is the true location of the perceived target, and the velocity corresponding to the box is the actual velocity of the perceived target #1, which can be greater than... and

[0195] Optional, the maximum speed within the speed measurement range corresponding to the K configurations. Satisfies formula (8):

[0196] Here, LCM represents the least common multiple operation. Δv1 is the velocity mesh. Δv1 can be related to the velocity resolution; for example, it can be the velocity resolution itself, or greater than or equal to the velocity resolution, or an integer multiple of the velocity resolution.

[0197] This relates to the i-th configuration out of K configurations, where i is an integer from 1 to K. Optional, It can be based on The value obtained; It is the maximum unambiguous speed corresponding to the i-th configuration. The quantized value; or, It is the maximum unambiguous speed corresponding to the frequency band information and periodic information in the i-th configuration. The quantized value. Among them, T i It is the period indicated by the period information in the i-th configuration; λ i It is f i The corresponding wavelength, f i This refers to the frequency band indicated by the frequency band information in the i-th configuration. Accordingly, the second device can determine the maximum unambiguous speed corresponding to the i-th configuration based on the i-th configuration. Thus determine And according to Sure

[0198] For example, Can be Retain k decimal places, where k is a positive integer or 0. For example, if Given 2.579, Δv1 = 1, and k = 2, then Wherein, k can be pre-set, such as as specified in the protocol; or it can be determined by the second device; or it can be indicated by other devices (e.g., the first device, the third device, or the core network equipment) to the second device.

[0199] The following is about It can be based on Examples of the obtained values ​​are provided. It should be understood that... It can also be determined through other methods, without any restrictions.

[0200] In some examples, For example, if Given 0.579, Δv1 = 1, and k = 1, then...

[0201] In other examples, Can be reserved The value obtained by selecting P significant bits, where P is a positive integer. For example, P can be a power of 2, where n is a positive integer. For example, if Given 2.579, Δv1 = 1 m / s, k = 2, and P = 1, then...

[0202] In some other examples, `round` represents rounding operations. For example, if... Given 2.579, Δv1 = 1 m / s, and k = 2, then

[0203] In some other examples, Can be used as a pair The value obtained by rounding up. For example, if Given 2.579, Δv1 = 1 m / s, and k = 2, then

[0204] In some other examples, Can be used as a pair The value obtained by rounding down. For example, if Given 2.579, Δv1 = 1 m / s, and k = 2, then

[0205] The following example illustrates formula (8).

[0206] For example, the K configurations include three configurations, which are respectively related to... and Corresponding. If It is 2. It is 3. If Δv1 is 11 and Δv1 is 1m / s, then the maximum speed in the speed measurement range corresponding to the K configurations can be 66m / s.

[0207] This method can effectively expand the speed measurement range and reduce or avoid speed measurement ambiguity.

[0208] Optionally, in this method, steps S502 and S504 are optional.

[0209] For example, the method shown in Figure 5 does not include S502. In S503, the first device outputs a sensing signal based on the frequency band information and period information in each of the K configurations; the second device can blindly detect the sensing signal, thereby receiving the sensing signal transmitted according to the frequency band information and period information in each configuration.

[0210] For example, the method shown in Figure 5 may not include S504. The second device may send the detected raw sensing data to the third device, and the third device performs sensing based on the raw sensing data to obtain a sensing result.

[0211] Using the method shown in Figure 5, the first information can be used to configure resources for transmitting the sensing signal; correspondingly, the first device can accurately determine the resources for transmitting the sensing signal based on the first information. Furthermore, in this method, the first device can output the sensing signal based on frequency band information and periodic information from multiple configurations, thereby expanding the unambiguous range of speed measurement and reducing the overhead of sensing time-domain resources.

[0212] For example, the maximum speed of the target in the sensing scenario is 120 km / h (approximately 33.3 m / s); the SCS corresponding to the sensing signal is 30 kHz, and correspondingly, the length of one symbol is approximately 0.5 ms / 14 = 0.0357 ms. When the sensing scenario is as shown in Figure 4D, the value of k1 can be close to 2. If the frequency band f1 corresponding to the first configuration is 28GHz and the period T1 corresponding to the first configuration is 0.89ms, then the maximum unambiguous speed corresponding to the first configuration is... If the frequency band f2 corresponding to the second configuration is 10GHz and the period T2 corresponding to the second configuration is 0.68ms, then the maximum unambiguous speed corresponding to the second configuration is... If Δv1 = 1, then the maximum speed in the velocity measurement range corresponding to the K configurations can be 33 m / s. In this case, in the frequency band corresponding to the first configuration, one symbol out of every 25 symbols is used for sensing; in the frequency band corresponding to the second configuration, one symbol out of every 19 symbols is used for sensing. The overhead of sensing time domain resources is approximately 4.6%, which can significantly reduce the overhead of sensing time domain resources.

[0213] Among the possible configurations, K configurations include a first configuration and a second configuration. The first and second configurations can satisfy the following conditions: #a1, #a2, or #a3.

[0214] Condition #a1: The frequency band information in the first configuration is the same as that in the second configuration, but the period information in the first configuration is different from that in the second configuration.

[0215] Wherein, the frequency band information in the first configuration is the same as the frequency band information in the second configuration, and can be replaced with (or can be understood as) at least one of the following: the frequency band indicated by the frequency band information in the first configuration is the same as the frequency band indicated by the frequency band information in the second configuration; the frequency band corresponding to (or indicating or configuring) the first configuration is the same as the frequency band corresponding to (or indicating or configuring) the second configuration; or, the frequency band of the resource corresponding to the first configuration is the same as the frequency band of the resource corresponding to the second configuration.

[0216] The period information in the first configuration is different from the period information in the second configuration, and can be replaced with (or understood as) at least one of the following: the period indicated by the period information in the first configuration is the same as the period indicated by the period information in the second configuration; the period corresponding to (or indicating or configuring) the first configuration is different from the period corresponding to (or indicating or configuring) the second configuration; or, the period of the resource corresponding to the first configuration is different from the period of the resource corresponding to the second configuration.

[0217] For example, the frequency band information in the first configuration indicates frequency band f1, and the period information in the first configuration indicates period T1. The first configuration can configure resources with frequency band f1 and period T1, for example, the sensing resources shown in (1) of Figure 8A can be configured. The frequency band information in the second configuration indicates frequency f1, and the period information in the second configuration indicates period T2. The second configuration can configure resources with frequency band f1 and period T2, for example, the sensing resources shown in (2) of Figure 8A can be configured.

[0218] When the first configuration and the second configuration satisfy condition #a1, the frequency band information in the first configuration is the same as that in the second configuration, thereby saving frequency domain resources used for transmitting sensing signals.

[0219] Optionally, if the first configuration and the second configuration satisfy condition #a1, the first information may indicate frequency band information for the first configuration and the second configuration respectively (e.g., as shown in Table 2A); or, the first information may indicate a frequency band information (e.g., as shown in Table 2B), which can be shared by the first configuration and the second configuration, thereby saving the signaling overhead of indicating frequency band information.

[0224] The period information in the first configuration is the same as the period information in the second configuration, and can be replaced with (or understood as) at least one of the following: the period indicated by the period information in the first configuration is the same as the period indicated by the period information in the second configuration; the period corresponding to (or indicating or configuring) the first configuration is the same as the period corresponding to (or indicating or configuring) the second configuration; or, the period of the resource corresponding to the first configuration is the same as the period of the resource corresponding to the second configuration.

[0225] For example, the frequency band information in the first configuration indicates frequency f1, the period information in the first configuration indicates period T1, and the first configuration can configure resources with frequency band f1 and period T1, for example, the sensing resources shown in (1) of Figure 8B can be configured. The frequency band information in the second configuration indicates frequency band f2, the period information in the second configuration indicates period T1, and the second configuration can configure resources with frequency band f2 and period T1, for example, the sensing resources shown in (2) of Figure 8B can be configured.

[0226] Optionally, if the first configuration and the second configuration satisfy condition #a2, the first information may indicate periodic information for the first configuration and the second configuration respectively (e.g., as shown in Table 3A); or, the first information may indicate a periodic information (e.g., as shown in Table 3B), which may be shared by the first configuration and the second configuration, thereby saving the signaling overhead of indicating periodic information.

Here, the starting position can be the starting position in the time domain; and / or, the ending position can be the ending position in the time domain. In this application, the ending position can also be referred to as the end position.

[0233] For example, the resource corresponding to the first configuration may be the sensing resource shown in (1) of Figure 8A (hereinafter referred to as resource #1); the resource corresponding to the second configuration may be the sensing resource shown in (2) of Figure 8A (hereinafter referred to as resource #3). The starting position of resource #1 is the same as the starting position of resource #3; and / or, the ending position of resource #1 is the same as the ending position of resource #3.

[0234] For example, the resource corresponding to the first configuration may be the sensing resource shown in (1) of Figure 8B (hereinafter referred to as resource #1); the resource corresponding to the first configuration may be the sensing resource shown in (2) of Figure 8B (hereinafter referred to as resource #4).

The starting position of resource #1 is the same as the starting position of resource #2; and / or, the ending position of resource #1 is the same as the ending position of resource #2.

[0236] Optionally, there can be multiple ways to determine the start and / or end positions of the resources defined by the first configuration. In some examples, the start and / or end positions of the resources corresponding to the first configuration can be semi-statically configured, for example, indicated by an RRC message. In other examples, the start and / or end positions of the resources corresponding to the first configuration can be dynamically indicated, for example, indicated by a DCI.

[0237] The method for determining the start and / or end position of the resource corresponding to the second configuration can be found in the description of "the method for determining the start and / or end position of the resource corresponding to the first configuration", except that the first configuration is replaced with the second configuration, and will not be repeated here.

[0238] It should be understood that the above explanation uses the first and second configurations as examples. Optionally, any two of the K configurations can satisfy one of conditions #a1 to #a3. The conditions satisfied by two different configurations among the K configurations can be the same or different.

[0239] In some examples, every two configurations out of the K configurations can satisfy condition #a1. For example, configuration #i and configuration #j are any two configurations out of the K configurations, where i and j are integers from 1 to K. The frequency band information in configuration #i is the same as that in configuration #j; the period information in configuration #i is different from that in configuration #j.

The explanation will not be repeated here. This is the value obtained from the quantization of the maximum unambiguous speed corresponding to the j-th configuration among the K configurations. For details, please refer to S504. The explanation is simply replacing i with j, and will not be repeated here.

[0248] For example, It is 3. It is 7, and 3 and 7 are coprime.

[0249] For example, It is 3. 10, 3 and 10 are coprime.

[0250] Optionally, the i-th configuration and the j-th configuration are any two of the K configurations; in other words, the values ​​obtained by quantizing the maximum unambiguous speed corresponding to any two of the K configurations are coprime.

[0251] For example, the values ​​obtained from the quantization of the maximum unambiguous speed corresponding to each of the K configurations include: and It is 3. It is 4. The result is 5. Any two values ​​among 3, 4, and 5 are coprime.

[0252] In this way, and Coprime. Because the maximum speed of the speed measurement range corresponding to the K configurations is... Positive correlation, LCM means least common multiple operation, so this method can make the speed measurement range corresponding to K configurations as large as possible, thereby expanding the range of speed measurement without ambiguity and reducing the overhead of sensing time domain resources.

[0253] In some possible approaches, given that the frequency band information in the K configurations is determined, the period information in the K configurations can maximize the least common multiple of the K values. Accordingly, given that the frequency band information in the K configurations is determined, the third device can select the period information that maximizes the least common multiple of the K values ​​as the period information in the K configurations.

[0254] The frequency band information in the K configurations can be replaced with at least one of the following: the frequency band indicated by the frequency band information in the K configurations; or the frequency band indicated by the K configurations. The period information in the K configurations can be replaced with at least one of the following: the period indicated by the period information in the K configurations; or the period indicated by the K configurations.

[0255] The K values ​​can be one of the following: the maximum unambiguous speed corresponding to each of the K configurations, the quantized value of the maximum unambiguous speed corresponding to each of the K configurations, or the value obtained based on the quantized value of the maximum unambiguous speed corresponding to each of the K configurations. These will be explained below.

[0256] 1. The maximum unambiguous speed value corresponding to each of the K configurations.

[0257] Optional, the K values ​​include: in, The maximum unambiguous speed corresponding to the i-th configuration among the K configurations; or, in other words, Let i be the maximum unambiguous speed corresponding to the frequency band information and period information in the i-th configuration. i takes integer values ​​from 1 to K. For details, please refer to S504. The explanation will not be repeated here.

[0259] Optional, the K values ​​include: in, The maximum unambiguous speed corresponding to the i-th configuration among K configurations. The quantized value; or, The maximum unambiguous speed corresponding to the frequency band information and periodic information in the i-th configuration. The quantized value of i. i takes integers from 1 to K. For details, please refer to S504. The explanation will not be repeated here.

[0260] 3. The value obtained from the quantization value of the maximum unambiguous speed corresponding to each of the K configurations.

[0261] Optional, the K values ​​include: in, The quantization value of the maximum unambiguous speed corresponding to the i-th configuration among the K configurations. The value obtained; or rather, The quantization value of the maximum unambiguous velocity corresponding to the frequency band information and periodic information in the i-th configuration. The value obtained. For details, please refer to S504. The explanation will not be repeated here.

[0262] The following are K values: For example, let's illustrate the statement that "when the frequency band information in K configurations is determined, the period information in K configurations can maximize the least common multiple of the K values".

[0263] In some examples, when the perceived scene is as shown in Figure 4D, the value of k1 can be close to 2. K is 2. The frequency band information in the K configurations indicates two frequency bands, 3.5 GHz and 10 GHz, with corresponding wavelengths of 0.0857 meters (m) and 0.03 meters (m), respectively. The SCS corresponding to the K configurations is 30 kHz, and correspondingly, the length of one symbol is approximately 0.5 / 14 = 0.0357 ms. In this case, the maximum unambiguous speed corresponding to the K configurations is... and They satisfy formulas (9) and (10) respectively:

[0264] Where Q1 and Q2 are integers, representing the number of symbols.

[0265] exist And when Δv1 is 0.8 m / s (which can be used to distinguish pedestrians), and They satisfy formulas (11) and (12) respectively:

[0266] When Q1 = 7 and Q2 = 2 and Coprime, thus making and Maximize the least common multiple. In this case, one of the K configurations may include: frequency band information indicating 3.5 GHz and period information indicating 7 symbols; another of the K configurations may include: frequency band information indicating 10 GHz and period information indicating 2 symbols.

[0267] In other examples, when the perceived scene is as shown in Figure 4D, the value of k1 can be close to 2. K is 2. The frequency band information in the K configurations indicates two frequency bands, 3.5 GHz and 10 GHz, with corresponding wavelengths of 0.0857 meters (m) and 0.03 meters (m), respectively. The SCS corresponding to the K configurations is 30 kHz, and correspondingly, the length of one time slot is approximately 0.5 ms. In this case, the maximum unambiguous speed corresponding to the K configurations is... and They satisfy formulas (13) and (14) respectively:

[0268] Q3 and Q4 are integers representing the number of time slots.

[0269] exist And when Δv1 is 0.8 m / s (which can be used to distinguish pedestrians), and They satisfy formulas (15) and (16) respectively:

[0270] When Q3 = 1 and Q4 = 1 and Coprime, thus making and Maximize the least common multiple. In this case, one of the K configurations may include: frequency band information indicating 3.5 GHz and period information indicating 1 time slot; another of the K configurations may include: frequency band information indicating 10 GHz and period information indicating 1 time slot.

[0271] In this way, the frequency band and period information in the K configurations can maximize the least common multiple of the K values. Since the maximum speed of the speed measurement range corresponding to the K configurations is... Positive correlation, LCM means least common multiple operation, so this method can maximize the speed measurement range corresponding to K configurations, thereby expanding the range of unambiguous speed measurement and reducing the overhead of sensing time domain resources.

[0272] In other possible approaches, given that the frequency band information in the K configurations is determined, the periodic information in the K configurations ensures that the least common multiple of the K values ​​is greater than a first threshold. Accordingly, given that the frequency band information in the K configurations is determined, the third device can select the periodic information that ensures the least common multiple of the K values ​​is greater than the first threshold as the periodic information in the K configurations.

[0273] The frequency band information in the K configurations can be replaced with at least one of the following: the frequency band indicated by the frequency band information in the K configurations; or the frequency band indicated by the K configurations. The period information in the K configurations can be replaced with at least one of the following: the period indicated by the period information in the K configurations; or the period indicated by the K configurations.

[0274] For details on the K values, please refer to the explanation of the K values ​​above, which will not be repeated here.

[0275] Optionally, the first threshold can be greater than or equal to the maximum speed to be measured. For example, if the maximum speed to be measured is 30 m / s, the first threshold can be 30 m / s, or it can be a speed greater than 30 m / s.

[0276] The following are K values: For example, let's illustrate the statement that "when the frequency band information in K configurations is determined, the period information in K configurations makes the least common multiple of the K values ​​greater than the first threshold".

[0277] In some examples, when the perceived scene is as shown in Figure 4D, the value of k1 can be close to 2. K is 2. The frequency band information in the K configurations indicates two frequency bands, 3.5 GHz and 10 GHz, with corresponding wavelengths of 0.0857 m and 0.03 m, respectively. The SCS corresponding to the K configurations is 30 kHz, and correspondingly, the length of one symbol is approximately 0.5 / 14 = 0.0357 ms. In this case, the maximum unambiguous speed corresponding to the K configurations is... and These satisfy formulas (9) and (10) respectively. And when Δv1 is 0.8 m / s (which can be used to distinguish pedestrians), and They satisfy formulas (11) and (12) above, respectively.

[0278] Assuming the maximum speed to be measured is 100 m / s, the first threshold is 100 / Δv1 = 100 / 0.8 = 125. When Q1 = 39 and Q2 = 37, and Coprime. and The least common multiple is 133, which is greater than the first threshold. In this case, one of the K configurations may include: frequency band information indicating 3.5 GHz and period information indicating 39 symbols; another of the K configurations may include: frequency band information indicating 10 GHz and period information indicating 37 symbols.

[0279] In other examples, when the perceived scene is as shown in Figure 4D, the value of k1 can be close to 2. K is 2. The frequency band information in the K configurations indicates two frequency bands, 3.5 GHz and 10 GHz, with corresponding wavelengths of 0.0857 m and 0.03 m, respectively. The SCS for the K configurations is 30 kHz, and correspondingly, the length of one time slot is approximately 0.5 ms. In this case, the maximum unambiguous speed corresponding to the K configurations is... and These satisfy formulas (13) and (14) respectively. And when Δv1 is 0.8 m / s (which can be used to distinguish pedestrians), and They satisfy formulas (15) and (16) above, respectively.

[0280] Assuming the maximum speed to be measured is 100 m / s, the first threshold is 100 / Δv1 = 100 / 0.8 = 125. When Q3 = 4 and Q4 = 1, and Coprime. and The least common multiple is 247, which is greater than the first threshold. In this case, one of the K configurations may include: frequency band information indicating 3.5 GHz and period information indicating 4 time slots; another of the K configurations may include: frequency band information indicating 10 GHz and period information indicating 1 time slot.

[0281] In this way, the frequency band and period information in the K configurations can ensure that the least common multiple of the K values ​​is greater than the first threshold. This is because the maximum speed of the speed measurement range corresponding to the K configurations is... The positive correlation means that this method can ensure that the speed measurement ranges corresponding to K configurations meet the threshold requirements, thereby expanding the range of unambiguous speed measurement and reducing the overhead of sensing time domain resources.

[0282] There are multiple ways to determine the first threshold, for example, at least one of methods a1 to a3.

[0283] Method a1: The third device receives information indicating the first threshold, and can determine the first threshold based on the information.

[0284] In some implementations, a first device sends first threshold information; correspondingly, a third device receives the first threshold information. The first threshold information indicates a first threshold. The first threshold information can be carried in a conventional message (e.g., a sensing service request) or in a new message. For example, the first threshold information can be carried in an RRC message or a UCI. The first threshold information can have other names, such as first threshold indication information, etc., as long as they have the same meaning, they are all within the scope of protection of this application.

[0285] Optionally, in this implementation, the first device may send the first threshold information before receiving the first information; in other words, the first device may send the first threshold information before S501.

[0286] Through this implementation, the third device can accurately determine the first threshold based on the first threshold information.

[0287] In other implementations, the second device sends second threshold information; correspondingly, the third device receives the second threshold information. The second threshold information indicates the first threshold. The second threshold information can be carried in a conventional message (e.g., a sensing service request) or in a new message. For example, the second threshold information can be carried in an RRC message or a UCI. The second threshold information can have other names, such as second threshold indication information, etc., as long as they have the same meaning, they are all within the scope of protection of this application.

[0288] Optionally, in this implementation, the second device may send the second threshold information before receiving the first information; in other words, the second device may send the second threshold information before S502.

[0289] Through this implementation, the third device can accurately determine the first threshold based on the second threshold information.

[0290] It should be understood that the above implementation is merely an example, and the third device may also receive information indicating the first threshold from other devices (e.g., core network equipment).

[0291] Method a2: The first threshold is determined by the third device itself, and the method of determination is not limited.

[0292] Method a3: The first threshold can be preset, for example, as specified in the protocol. In this way, the third device can accurately determine the first threshold.

[0293] In other possible approaches, the K configurations can be selected from a configuration set; in other words, the frequency band information and periodic information in the K configurations can be determined based on the configuration set. The configuration set can be represented in a table or other ways. The configuration set can be pre-defined, such as as specified in a protocol; or it can be determined by a third device; or it can be notified to a third device by another device (e.g., a first device, a second device, or a core network device). The configuration set can also have other names, such as a configuration list, etc., as long as they have the same function, they are all within the scope of protection of this application.

[0294] For example, the configuration set is shown in Table 4A or Table 4B, where each row represents a configuration. When two frequency bands are to be selected for speed measurement, the third device can select two rows from Table 4A or Table 4B such that the maximum speed in the speed measurement range corresponding to these two rows is achieved. The requirements are met. For example, the third device can select two rows from Table 4A or Table 4B such that the maximum speed in the speed measurement range corresponding to these two rows is achieved. Maximize; or, the third device can select two rows from Table 4A or Table 4B such that the maximum speed is within the speed measurement range corresponding to those two rows. Greater than the threshold. For details, please refer to S504 above. The explanation will not be repeated here.

[0295] For example, if the maximum speed to be measured is 100 m / s, the third device can select the first and second rows in Table 4A, which correspond to... Alternatively, the third device can select the first and third rows in Table 4A, which correspond to

[0296] For example, if the maximum speed to be measured is 100 m / s, the third device can select the first and second rows in Table 4B, which correspond to... Alternatively, the third device can be selected from the second and third rows of Table 4B, which correspond to

[0297] Table 4A

[0298] Table 4B

[0299] It should be understood that Tables 4A and 4B are merely examples. Any new table content obtained by reasonable modification, supplementation, or deletion of the content in Tables 4A and 4B shall fall within the scope of protection of this application.

[0300] Optionally, in Table 4A or Table 4B, the normalization rates corresponding to different rows are coprime.

[0301] In some possible configurations, the K configurations include a first configuration and a second configuration, wherein the first configuration and the second configuration satisfy at least one of the following conditions #b1 to #b3. Accordingly, the third device selects a configuration that satisfies at least one of the following conditions #b1 to #b3 as the configuration among the K configurations.

[0302] Condition #b1: The difference between the maximum unambiguous speed corresponding to the first configuration and the maximum unambiguous speed corresponding to the second configuration is greater than the second threshold.

[0303] For example, the maximum unambiguous speed corresponding to the first configuration is The maximum unambiguous speed corresponding to the second configuration is: exist and If the difference between the first and second configurations is greater than the second threshold, then the first and second configurations satisfy condition #b1. and For details, please refer to S504. The explanation is simply replacing i with 1 and 2, and will not be repeated here.

[0304] Optionally, condition #b1 can be replaced with: the absolute value of the difference between the maximum unambiguous speed corresponding to the first configuration and the maximum unambiguous speed corresponding to the second configuration is greater than the second threshold.

[0305] Optionally, the first configuration and the second configuration can be any two of the K configurations. Under this condition, condition #b1 can be replaced with: Greater than the second threshold, and Let i be the maximum unambiguous speed corresponding to any two of the K configurations. i and j are integers greater than or equal to 1 and less than or equal to K, and i and j are distinct. For details, please refer to S504. The explanation is simply replacing i with j, and will not be repeated here.

[0306] The second threshold may be pre-set, such as as specified in the protocol; or it may be determined by a third device; or it may be notified to the third device by other devices (e.g., one or more of the first device, the second device, or the core network equipment).

[0307] Condition #b2: The difference between the first quantization value and the second quantization value is greater than the third threshold. The first quantization value is the quantization value of the maximum unambiguous speed corresponding to the first configuration, and the second quantization value is the quantization value of the maximum unambiguous speed corresponding to the second configuration.

[0308] For example, the maximum unambiguous speed corresponding to the first configuration is The first quantization value is The maximum unambiguous speed corresponding to the second configuration is: The second quantization value is exist and If the difference between the two configurations is greater than the third threshold, then the first and second configurations satisfy condition #b2. and For details, please refer to S504. The explanation is simply replacing i with 1 and 2, and will not be repeated here.

[0309] Optionally, condition #b2 can be replaced with: the absolute value of the difference between the first quantization value and the second quantization value is greater than the third threshold.

[0310] Optionally, the first and second configurations can be any two of the K configurations; in this case, condition #b2 can be replaced with: Greater than the third threshold, and Let i be the quantized value of the maximum unambiguous speed corresponding to any two of the K configurations. i and j are integers greater than or equal to 1 and less than or equal to K, and i and j are distinct. For details, please refer to S504. The explanation is simply replacing i with j, and will not be repeated here.

[0311] The third threshold may be pre-set, such as as specified in the protocol; or it may be determined by the third device; or it may be notified to the third device by other devices (e.g., one or more of the first device, the second device, or the core network equipment).

[0312] Condition #b3: The difference between the value obtained from the first quantization and the value obtained from the second quantization is greater than the fourth threshold.

[0313] For example, the first quantization value is The value obtained from the first quantization value is The second quantization value is The value obtained from the first quantization value is exist and If the difference between the two configurations is greater than the fourth threshold, then the first and second configurations satisfy condition #b3. and For details, please refer to S504. The explanation is simply replacing i with 1 and 2, and will not be repeated here.

[0314] Optionally, condition #b3 can be replaced with: the absolute value of the difference between the value obtained from the first quantization and the value obtained from the second quantization is greater than the fourth threshold.

[0315] Optionally, the first and second configurations can be any two of the K configurations; in this case, condition #b3 can be replaced with: Greater than the fourth threshold, and This is the value obtained from the quantization of the maximum unambiguous speed corresponding to any two of the K configurations. i and j are integers greater than or equal to 1 and less than or equal to K, and i and j are distinct. For details, please refer to S504. The explanation is simply replacing i with j, and will not be repeated here.

[0316] The fourth threshold may be pre-set, such as as specified in the protocol; or it may be determined by the third device; or it may be notified to the third device by other devices (e.g., one or more of the first device, the second device, or the core network equipment).

[0317] As mentioned earlier, the first information can indicate K configurations. The value of K can be determined in several ways, such as at least one of the methods b1 to b3.

[0318] Method b1: The third device receives information indicating the value of K, and can determine the value of K based on the information.

[0319] In some implementations, the first device may send the second information; correspondingly, the third device receives the second information. The second information may indicate the value of K. The second information may be carried in a conventional message (e.g., a sensing service request) or in a new message. For example, the second information may be carried in an RRC message or a UCI. The second information may have other names, such as configuration quantity indication information, etc., as long as they have the same meaning, they are all within the scope of protection of this application.

[0320] Optionally, in this implementation, the first device may send the second information before receiving the first information; in other words, the first device may send the second information before S501. Furthermore, the first threshold information and the second information may be carried in the same message or in different messages. When the first threshold information and the second information are carried in different messages, the order in which they are sent is not limited.

[0321] Through this implementation, the third device can accurately determine the value of K based on the second information.

[0322] In other implementations, the second device may send third information; correspondingly, the third device receives the third information. The third information may indicate the value of K. The third information may be carried in a conventional message (e.g., a sensing service request) or in a new message. For example, the third information may be carried in an RRC message or a UCI. The third information may have various names, such as configuration quantity indication information, etc., as long as they have the same meaning, they are all within the scope of protection of this application.

[0323] Optionally, in this implementation, the second device may send the third information before receiving the first information; in other words, the second device may send the third information before S502. Furthermore, the second threshold information and the third information may be carried in the same message or in different messages. When the second threshold information and the third information are carried in different messages, the order in which they are sent is not limited.

[0324] Through this implementation, the third device can accurately determine the value of K based on the third information.

[0325] It should be understood that the above implementation is merely an example, and the third device may also receive information indicating the value of K from other devices (e.g., core network equipment).

[0326] Method b2: The value of K is determined by the third device itself, and the method of determination is not limited.

[0327] Method b3: The value of K can be preset, such as as specified in the protocol. In this way, the third device can accurately determine the value of K.

[0328] In some possible ways, the first information may indicate the number of time units corresponding to the periodic information in each of the K configurations.

[0329] For example, the number of time slots corresponding to the periodic information in the i-th configuration among the K configurations indicated by the first information is M. i In the case where the period information in the i-th configuration indicates a period of M... i One time slot. M i Let i be a positive integer. Let i be any integer from 1 to K.

[0330] For example, the number of symbols corresponding to the periodic information in the i-th configuration among the K configurations indicated by the first information is N. i In the case where the period information in the i-th configuration indicates a period of N. i A symbol. N i Let i be a positive integer. Let i be any integer from 1 to K.

[0331] For example, in the first information indicating K configurations, the number of time slots corresponding to the periodic information in the i-th configuration is M. i The number of signs is N i In the case where the period information in the i-th configuration indicates a period of M... i N time slots i There are 1 to 1 K symbols. i takes any integer from 1 to K.

[0332] In this manner, the device receiving the first information (e.g., the first device and / or the second device) can accurately determine the period indicated by the period information in each of the K configurations based on the number of time units corresponding to the period information in each configuration.

[0333] Among the possible approaches, there are multiple ways to determine the length of the time unit corresponding to the periodic information in each of the K configurations, such as approach c1 or approach c2.

[0334] Method c1: The first information indicates the length of the time unit corresponding to the periodic information in each of the K configurations.

[0335] In some implementations, the first information may explicitly indicate the length of the time unit corresponding to the periodic information in each of the K configurations. For example, the K configurations include configuration #1 to configuration #2. The first information may indicate that the time slot corresponding to the periodic information in configuration #1 has a length of 1ms, and the time slot corresponding to the periodic information in configuration #2 has a length of 0.5ms.

[0336] In other implementations, the first information may implicitly indicate the length of the time unit corresponding to the periodic information in each of the K configurations. For example, the first information may indicate the SCS corresponding to the periodic information in each of the K configurations, and the SCS corresponding to the periodic information in each configuration can be used to determine the length of the time unit corresponding to the periodic information in each configuration. For example, the K configurations include configurations #1 to #2. The first information may indicate that the SCS corresponding to the periodic information in configuration #1 is 15kHz, and the SCS corresponding to the periodic information in configuration #2 is 30kHz. In this case, the length of the time slot corresponding to the periodic information in configuration #1 is 1ms, and the length of the time slot corresponding to the periodic information in configuration #2 is 0.5ms.

[0337] Optionally, a correspondence exists between μ and SCS (hereinafter referred to as the first correspondence). The first information can indicate the SCS corresponding to the periodic information in each of the K configurations by indicating the μ corresponding to the periodic information in each configuration. For example, the first correspondence is shown in Table 5. The K configurations include configurations #1 to #2. The first information can indicate that the μ corresponding to the periodic information in configuration #1 is 0, and the μ corresponding to the periodic information in configuration #2 is 1. In this case, the SCS corresponding to the periodic information in configuration #1 is 15kHz, and the SCS corresponding to the periodic information in configuration #2 is 30kHz.

[0338] Table 5

[0339] It should be understood that Table 5 is merely an example. Any reasonable modification, addition, or deletion of the content in Table 5 to obtain new table content falls within the scope of protection of this application.

[0340] In mode c1, the device receiving the first information (e.g., the first device and / or the second device) can accurately determine the length of the time unit corresponding to the periodic information in each of the K configurations based on the first information. Furthermore, in mode c1, the length of the time unit can be indicated by the third device, thus allowing the third device to flexibly configure resources for time units of various lengths.

[0341] Method c2: The length of the time unit corresponding to the periodic information in each of the K configurations is preset, such as as specified by the protocol. For example, the length of the time slot corresponding to the periodic information in each of the K configurations is preset to 1ms. Or, for example, the length of the time slot corresponding to the periodic information in each of the K configurations is preset to 0.5ms.

[0342] Using method c2, the first device can accurately determine the length of the time unit corresponding to the periodic information in each of the K configurations.

[0343] Optionally, after determining the number of time units corresponding to the periodic information in each of the K configurations, and the length of the time units, the first device can determine the period indicated by the periodic information in each of the K configurations. For example, the K configurations include configurations #1 to #2. The first information indicates that the time slot corresponding to the periodic information in configuration #1 is 3, and the time slot corresponding to the periodic information in configuration #2 is 4. If, according to mode c1 or mode c2, the first device determines that the length of the time slot corresponding to the periodic information in configuration #1 is 1ms, and the length of the time slot corresponding to the periodic information in configuration #2 is 0.5ms, then the first device can determine that the period indicated by the periodic information in configuration #1 is 3ms, and the period indicated by the periodic information in configuration #2 is 2ms.

[0344] Among some possible approaches, the method shown in Figure 5 also includes S505:

[0345] S505: The first device sends the first frequency band indication information; correspondingly, the third device receives the first frequency band indication information.

[0346] The first frequency band indication information indicates L1 frequency bands supported by the first device, where L1 is a positive integer. These L1 frequency bands include the frequency bands indicated by the frequency band information in the configuration. The first device may be a first apparatus or the device in which the first apparatus is located.

[0347] Optional. The L1 bands supported by the first device may include, for example, bands from FR1, FR2, or FR3. The frequency range corresponding to FR1 is 410MHz-7125MHz, the frequency range corresponding to FR2 is 24250MHz-52600MHz, and the frequency range corresponding to FR3 is 6425MHz-7125MHz.

[0348] For example, the L1 frequency bands supported by the first device may include the n1 to n3 frequency bands in Table 1 above. The frequency bands indicated by the frequency band information in the K configurations may include at least two of the n1 to n3 frequency bands.

[0349] The first band indication information can be carried in traditional messages (e.g., messages in the capability information exchange process) or in new messages. For example, the first band indication information can be carried in an RRC message or in UCI (uplink control information).

[0350] The first frequency band indication information may have other names, such as capability information or frequency band information, as long as it has the same function, it is within the protection scope of this application.

[0351] Optionally, S505 can precede S501 and / or S502.

[0352] In this way, the first device can indicate to the third device the L1 frequency bands supported by the first device. In this way, the third device can configure sensing resources for the first device that are adapted to the capabilities of the first device. For example, it can configure sensing resources for the frequency bands supported by the first device, thereby improving sensing performance.

[0353] Among some possible approaches, the method shown in Figure 5 also includes S506:

[0354] S506: The second device sends the second frequency band indication information; correspondingly, the third device receives the second frequency band indication information.

[0355] The second frequency band indication information indicates the L2 frequency bands supported by the second device, where L2 is a positive integer, and the L2 frequency bands include the frequency bands indicated by the frequency band information in the configuration. The second device may be a second apparatus or the device in which the second apparatus is located.

[0356] For details of S506, please refer to S505, except that the first device is replaced with the second device and the first frequency band indication information is replaced with the second frequency band indication information, which will not be repeated here.

[0357] Optionally, S506 can precede S501 and / or S502. The order of S505 and S506 is not limited.

[0358] In this way, the second device can indicate to the third device the L2 frequency bands supported by the second device. In this way, the third device can configure sensing resources for the second device that are adapted to the capabilities of the second device. For example, it can configure sensing resources for the frequency bands supported by the second device, thereby improving sensing performance.

[0359] This application provides another communication method. Figure 9 is a flowchart illustrating the communication method provided in this application. As shown in Figure 9, the method includes:

[0360] S901: The third device sends the fourth message.

[0361] Correspondingly, the first device can receive the fourth information, as shown in S901a.

[0362] Optionally, the second device may receive fourth information, as shown in S901b.

[0363] In some possible ways, the fourth information may be information broadcast by the third device. In this case, S901a and S901b can be combined into: the third device can send the fourth information; correspondingly, the first device can receive the fourth information, and the second device can receive the fourth information.

[0364] In other possible configurations, the fourth information may be unicast by the third device. In this case, the third device may send the fourth information to both the first and second devices. The order in which the third device sends the fourth information to the first and second devices is not limited, i.e., the order of S901a and S901b is not limited.

[0365] The fourth information can indicate the first frequency band information and the first period information, which are used to transmit M1 sensing signals, where M1 is a positive integer. The fourth information indicating the first frequency band information and the first period information, used to transmit M1 sensing signals, can be replaced with (or understood as): the fourth information indicates the frequency band and period of the first resource, which can be used to transmit M1 sensing signals.

[0366] The specific details of the first frequency band information and the first cycle information will be explained below and will not be elaborated here.

[0367] The fourth information can indicate the first frequency band information and the first cycle information in various ways, such as explicitly or implicitly, without limitation. The following is an exemplary description of how the fourth information indicates the first cycle information.

[0368] In some possible ways, the fourth information may indicate the number of time units corresponding to the first periodic information. For example, if the fourth information indicates that the number of time slots corresponding to the first periodic information is M1, then the period corresponding to the first periodic information is M1 time slots. M1 is a positive integer. Another example is if the fourth information indicates that the number of symbols corresponding to the first periodic information is N1, then the period indicated by the first periodic information is N1 symbols. N1 is a positive integer. Yet another example is if the fourth information indicates that the number of time slots corresponding to the first periodic information is M1 and the number of symbols is N1, then the period indicated by the first periodic information is M1 time slots and N1 symbols.

[0369] Among the possible approaches, there are several ways to determine the length of the time unit corresponding to the first cycle information, such as approach d1 or approach d2.

[0370] Method d1: The fourth information indicates the length of the time unit corresponding to the first cycle information.

[0371] Method d2: The length of the time unit corresponding to the first cycle information is preset, for example, as specified in the protocol.

[0372] For details of methods d1 and d2, please refer to methods c1 and c2 in the method shown in Figure 5. The only difference is that the periodic information in each of the K configurations is replaced with the first periodic information, and the first information is replaced with the fourth information. No restrictions are imposed.

[0373] The fourth message can be carried in a traditional message or in a new message. For example, the fourth message can be carried in an RRC message, a MAC CE, or a DCI.

[0374] S902: If the first condition is met, the third device sends the fifth information.

[0375] Correspondingly, the first device can receive the fifth information, as shown in S902a.

[0376] Optionally, the second device may receive the fifth information, as shown in S902b.

[0377] In some possible configurations, the fifth information may be information broadcast by the third device. In this case, S902a and S902b can be combined into: the third device can send the fifth information; correspondingly, the first device can receive the fifth information, and the second device can receive the fifth information.

[0378] In other possible configurations, the fifth information may be unicast by the third device. In this case, the third device may send the fifth information to both the first and second devices. The order in which the third device sends the fifth information to the first and second devices is not limited, i.e., the order of S902a and S902b is not limited.

[0379] The fifth information indicates the second frequency band information and the second period information, which are used to transmit M2 sensing signals, where M2 is a positive integer. The fifth information indicating the second frequency band information and the second period information, used to transmit M2 sensing signals, can be replaced with (or understood as): the fifth information indicates the frequency band and period of the second resource, which can be used to transmit M1 sensing signals.

[0380] The specific details of the second frequency band information and the second cycle information will be explained below and will not be elaborated here.

[0381] The fifth information can indicate the second frequency band information and the second periodic information in various ways, such as explicitly or implicitly, without limitation. The following is an exemplary description of how the fifth information indicates the second periodic information.

[0382] In some possible ways, the fifth information may indicate the number of time units corresponding to the second periodic information. For example, if the fifth information indicates that the number of time slots corresponding to the second periodic information is M2, then the period corresponding to the second periodic information is M2 time slots. M2 is a positive integer. Another example is if the fifth information indicates that the number of symbols corresponding to the second periodic information is N2, then the period indicated by the second periodic information is N2 symbols. N2 is a positive integer. Yet another example is if the fifth information indicates that the number of time slots corresponding to the second periodic information is M2 and the number of symbols is N2, then the period indicated by the second periodic information is M2 time slots and N2 symbols.

[0383] Among the possible approaches, there are several ways to determine the length of the time unit corresponding to the second period information, such as approach e1 or approach e2.

[0384] Method e1: The fifth information indicates the length of the time unit corresponding to the second period information.

[0385] Method e2: The length of the time unit corresponding to the second cycle information is preset, for example, as specified in the protocol.

[0386] For details of methods e1 and e2, please refer to methods c1 and c2 in the method shown in Figure 5. The only difference is that the periodic information in each of the K configurations is replaced with the second periodic information, and the first information is replaced with the fifth information. There are no restrictions.

[0387] The fifth message can be carried in a traditional message or in a new message. For example, the fifth message can be carried in an RRC message, a MAC CE, or a DCI.

[0388] Using the method shown in Figure 9, the third device can update the resources used for transmitting sensing signals in a timely manner. Furthermore, in this method, the first device can output sensing signals based on first frequency band information and first period information, and also based on second frequency band information and second period information, thereby expanding the unambiguous range of speed measurement and reducing the overhead of sensing time-domain resources.

[0389] Among some possible approaches, the method shown in Figure 9 also includes S903 to S905:

[0390] S903: The first device outputs M1 sensing signals based on the first frequency band information and the first period information; correspondingly, the second device receives M1 sensing signals based on the first frequency band information and the first period information.

[0391] The first device outputs M1 sensing signals based on the first frequency band information and the first period information, which can be replaced (or understood as) at least one of the following: the first device can output M1 sensing signals based on the first resource indicated (or configured) by the fourth information; or, the first device can output M1 sensing signals on the frequency band indicated by the first frequency band information and at the period indicated by the first period information.

[0392] For details on the output of M1 sensing signals, please refer to the description of the output sensing signals in S503, which will not be repeated here.

[0393] The second device receives M1 sensing signals based on the first frequency band information and the first period information, which can be replaced (or understood as) at least one of the following: the second device can receive M1 sensing signals based on the first resource indicated (or configured) by the fourth information; or, the second device can receive M1 sensing signals on the frequency band indicated by the first frequency band information and at the period indicated by the first period information.

[0394] Receiving M1 sensing signals can be replaced with (or understood as): receiving the echo signals of M1 sensing signals.

[0395] For example, the first resource is the sensing resource shown in (1) of Figure 6 (hereinafter referred to as resource #1), and the first device can output a sensing signal through resource #1; correspondingly, the second device can receive a sensing signal through resource #1.

[0396] Optionally, in S903, the first device can output a sensing signal based on the first frequency band information and the first period information (as shown in S903a in Figure 9). This sensing signal first reaches the sensing target via wireless transmission, and then reaches the second device after being affected by the sensing target (e.g., reflection, scattering, or diffraction), that is, the second device can receive the sensing signal (as shown in S903b in Figure 9). In other words, S903 can include S903a and S903b in Figure 9. It should be understood that the sensing signal can be transmitted from the first device to the second device through one or more transmission paths; only one is shown in the figure.

[0397] Optionally, the M1 sensing signals may be some or all of the sensing signals output by the first device; and / or, the M1 sensing signals may be some or all of the sensing signals received by the second device, without limitation.

[0398] S904: The second device can sense based on M1 sensing signals.

[0399] Optionally, S904 can be replaced by at least one of the following: the second device processes the M1 sensing signals; the second device processes the echo signals of the M1 sensing signals; or, the second device performs sensing based on the echo signals of the M1 sensing signals.

[0400] The second device can perform sensing based on M1 sensing signals to obtain sensing results. The sensing results may include, for example, the position or velocity of the sensing target, and are not limited to these parameters. For details regarding the second device's measurement of the target's velocity based on the M1 sensing signals, please refer to the explanation of sensing velocity measurement in the terminology section above; it will not be repeated here.

[0401] S905: The second device sends the first sensing result to the third device.

[0402] Optionally, the first sensing result may include the first speed measurement result of the sensed target.

[0403] Optionally, S903 to S905 can be between S901 and S902.

[0404] In some other possible ways, the method shown in Figure 9 also includes S906 to S908:

[0405] S906: The first device outputs M2 sensing signals based on the second frequency band information and the second period information; correspondingly, the second device receives M2 sensing signals based on the second frequency band information and the second period information.

[0406] For details on S906, please refer to S903, except that the first frequency band information is replaced with the second frequency band information, the first cycle information is replaced with the second cycle information, and M1 is replaced with M2. The repeated parts will not be repeated.

[0407] Optionally, in S906, the first device can output a sensing signal based on the second frequency band information and the second periodic information (as shown in S906a in Figure 9). This sensing signal first reaches the sensing target via wireless transmission, and then reaches the second device after being affected by the sensing target (e.g., reflection, scattering, or diffraction), meaning the second device can receive the sensing signal (as shown in S906b in Figure 9). In other words, S906 can include S906a and S906b in Figure 9. It should be understood that the sensing signal can be transmitted from the first device to the second device through one or more transmission paths; only one is shown in the figure.

[0408] S907: The second device can sense based on M2 sensing signals.

[0409] For details on S907, please refer to S904, except that M1 is replaced by M2, which will not be repeated here.

[0410] S908: The second device sends the second sensing result to the third device.

[0411] The second sensing result may include the second velocity measurement result of the sensing target.

[0412] Optionally, S906 to S908 can be installed after S902.

[0413] In some possible ways, the first condition includes at least one of the following conditions #c1 to #c4:

[0414] Condition #c1: The absolute value of the actual speed of the perceived target is greater than the maximum unambiguous speed corresponding to the first frequency band information and the first period information.

[0415] Optionally, if the absolute value of the actual velocity of the sensed target is greater than the maximum unambiguous velocity corresponding to the first frequency band information and the first period information, it can be replaced with (or understood as): the first velocity measurement result is ambiguous, and the first velocity measurement result is determined based on some or all of the reference signals in the M1 sense signals. The first velocity measurement result is, for example, the first velocity measurement result in S905.

[0416] The maximum unambiguous velocity corresponding to the first frequency band information and the first period information can be determined based on the frequency band indicated by the first frequency band information and the period indicated by the first period information. For example, if the frequency band indicated by the first frequency band information is f1 and the period indicated by the first period information is T1, the maximum unambiguous velocity corresponding to frequency band f1 and period T1 is... For details, please refer to S504. The explanation is simply replacing i with 1, and will not be repeated here.

[0417] For example, when the absolute value of the actual velocity of the perceived target is 30 m / s, and the maximum unambiguous velocity corresponding to the first frequency band information and the first period information is 20 m / s, condition #c1 is satisfied.

[0418] In some implementations, when |v′*ΔT-d| is less than and In the case of one of the following, condition #c1 is satisfied; correspondingly, when |v′*ΔT-d| is less than and In the case of one of the following, the third device can determine that condition #c1 is satisfied. Where, v ′ The velocity of the sensed target is determined based on some or all of the M1 sensed signals; d is the distance (or movement distance or relative distance) of the sensed target within the time interval ΔT after v′ is determined. This represents the maximum unambiguous velocity corresponding to the first frequency band information and the first period information, where || indicates the absolute value operation.

[0419] For example, if v′ is 10 m / s, Given a speed of 20 m / s, a ΔT of 1 second, and a d of 30 meters, then |v′*ΔT-d|=20 meters. rice, meters. Since |v′*ΔT-d| is less than |(v′+ and One of them, therefore, condition #c1 is satisfied.

[0420] In this way, the third device can accurately determine whether condition #c1 is met, thereby updating the configuration of sensing resources in a timely manner and reducing or avoiding speed measurement ambiguity.

[0421] Condition #c2: Insufficient resources corresponding to the first frequency band information and the first cycle information.

[0422] For example, condition #c2 is satisfied when the resources corresponding to the first frequency band information and the first period information are insufficient to meet the speed measurement requirements. The inability of the resources corresponding to the first frequency band information and the first period information to meet the speed measurement requirements can be replaced with (or understood as): the maximum unambiguous velocity corresponding to the first frequency band information and the first period information is less than the maximum velocity to be measured. For example, if the maximum unambiguous velocity corresponding to the first frequency band information and the first period information is 20 m / s, and the maximum velocity to be measured is 30 m / s, then the resources corresponding to the first frequency band information and the first period information are insufficient.

[0423] Condition #c3: There is an overabundance of resources corresponding to the first frequency band information and the first cycle information.

[0424] For example, condition #c3 is satisfied when the resources corresponding to the first frequency band information and the first period information far exceed the resources required for speed measurement. The statement that the resources corresponding to the first frequency band information and the first period information far exceed the resources required for speed measurement can be replaced by at least one of the following: the maximum unambiguous speed corresponding to the first frequency band information and the first period information is much greater than the maximum speed to be measured; or, the resource difference between the resources corresponding to the first frequency band information and the first period information and the resources required for speed measurement is greater than a resource difference threshold; or, the speed difference between the maximum unambiguous speed corresponding to the first frequency band information and the first period information and the maximum speed to be measured is greater than a speed difference threshold. At least one of the resource difference threshold and the speed difference threshold can be pre-set, such as as specified in the protocol; or can be indicated to a third device by another device (e.g., a first device, a second device, or a core network device); or can be determined by a third device.

[0425] For example, if the maximum unambiguous velocity corresponding to the first frequency band information and the first periodic information is 100 m / s, and the maximum velocity to be measured is 30 m / s, then the resources corresponding to the first frequency band information and the first periodic information are excessive.

[0426] For example, if the speed difference threshold is 30, and the maximum unambiguous speed corresponding to the first frequency band information and the first period information is 100 m / s, and the maximum speed to be measured is 60 m / s, then the resources corresponding to the first frequency band information and the first period information are excessive.

[0427] Optionally, condition #c3 can be replaced with at least one of the following: There are too many resources corresponding to the first frequency band information and the first cycle information; The resources corresponding to the first frequency band information and the first cycle information exceed the resources required for speed measurement (or sensing).

[0428] Optionally, in conditions #c2 and #c3, the speed measurement requirement can be pre-set, such as as specified in the protocol; or it can be instructed by other devices (e.g., the first device, the second device, or the core network equipment) to the third device; or it can be determined by the third device.

[0429] Condition #c4: The third device receives the first request, which is used to request a change in the configuration of the sensing resources.

[0430] In some implementations, the third device may receive a first request from the first device and / or the second device. Optionally, the first device and / or the second device may send the first request if at least one of conditions #c1 to #c3 is satisfied.

[0431] Optionally, the first request may also indicate the reason for requesting a change in the configuration of the sensing resources, so that the third device can update the configuration of the sensing resources in a targeted manner based on the reason. For example, if the reason for requesting a change in the configuration of the sensing resources is that condition #c1 is met, the third device can determine that: the second frequency band information is different from the first frequency band information; and / or, the second periodic information is different from the first periodic information. As another example, if the reason for requesting a change in the configuration of the sensing resources is that condition #c2 is met, the third device can determine that: the second resources corresponding to the second frequency band information and the second periodic information are more than the first resources corresponding to the first frequency band information and the first periodic information. Yet another example, if the reason for requesting a change in the configuration of the sensing resources is that condition #c3 is met, the third device can determine that: the second resources corresponding to the second frequency band information and the second periodic information are less than the first resources corresponding to the first frequency band information and the first periodic information.

[0432] For example, the first request can indicate the reason for requesting a change in the configuration of the sensing resource via a reason value. For instance, the relationship between the reason value and the reason can be shown in Table 6.

[0433] Table 6

[0434] It should be understood that Table 6 is merely an example. Any reasonable modification, supplementation, or deletion of the content in Table 6 to obtain new table content falls within the scope of protection of this application.

[0435] In some possible ways, the first frequency band information, the second frequency band information, the first period information, and the second period information can satisfy the following conditions: #e1, #e2, or #e3.

[0436] Condition #e1: The information of the first frequency band is the same as that of the second frequency band, but the information of the first cycle and the information of the second cycle are different.

[0437] Condition #e2: The information of the first frequency band is different from that of the second frequency band, while the information of the first cycle is the same as that of the second cycle.

[0438] Condition #e3: The information of the first frequency band is different from that of the second frequency band, and the information of the first cycle is different from that of the second cycle.

[0439] The specific contents of conditions #e1 to #e3 can be referred to conditions #a1 to #a3 in the method shown in Figure 5, except that the frequency band information in the first configuration is replaced with the first frequency band information, the frequency band information in the second configuration is replaced with the second frequency band information, the period information in the first configuration is replaced with the first period information, and the period information in the second configuration is replaced with the second period information. It will not be described again.

[0440] Among some possible ways, and Coprime.

[0441] in, The value obtained based on the quantization value of the first maximum unambiguous velocity, where the first maximum unambiguous velocity is the maximum unambiguous velocity corresponding to the first frequency band information and the first period information; The value is obtained based on the quantization value of the second maximum unambiguous speed, which is the maximum unambiguous speed corresponding to the second frequency band information and the second period information.

[0442] and For details, please refer to S504. The explanation is simply replacing i with 1 and 2, and will not be repeated here.

[0443] The first maximum unambiguous speed is the maximum unambiguous speed corresponding to the first frequency band information and the first period information; the second maximum unambiguous speed is the maximum unambiguous speed corresponding to the second frequency band information and the second period information. For example, if the frequency band indicated by the first frequency band information is f1, and the period indicated by the first period information is T1, the maximum unambiguous speed corresponding to frequency band f1 and period T1 is... The second frequency band information indicates the frequency band f2, and the second period information indicates the period T2. The maximum unambiguous velocity corresponding to frequency band f2 and period T2 is: and For details, please refer to S504. The explanation is simply replacing i with 1 and 2, and will not be repeated here.

[0444] and For details on coprime, please refer to the method shown in Figure 5. and The explanation of coprime simply involves replacing i and j with either 1 or 2, and will not be repeated here.

[0445] In some possible approaches, given that the first frequency band information and the second frequency band information are determined, the first periodic information and the second periodic information maximize the least common multiple of the first value and the second value. Accordingly, given that the first frequency band information and the second frequency band information are determined, the third device may select the periodic information that maximizes the least common multiple of the first value and the second value as the first periodic information and the second periodic information.

[0446] In some implementations, the first value is the value of the first maximum unambiguous speed, and the second value is the value of the second maximum unambiguous speed. For details regarding the first and second maximum unambiguous speeds, please refer to the explanations above, which will not be repeated here.

[0447] In other implementations, the first value is the quantized value of the first maximum unambiguous speed, and the second value is the quantized value of the second maximum unambiguous speed. For example, the first maximum unambiguous speed is... The quantization value of the first maximum unambiguous speed is The second maximum unambiguous speed is The quantization value of the second maximum unambiguous speed is and For details, please refer to S504. The explanation is simply replacing i with 1 and 2, and will not be repeated here.

[0448] In some implementations, the first value is obtained based on the quantization value of the first maximum unambiguous speed, and the second value is obtained based on the quantization value of the second maximum unambiguous speed. For example, the quantization value of the first maximum unambiguous speed is... The value obtained based on the quantization value of the first maximum unambiguous velocity is The quantization value of the second maximum unambiguous speed is The value obtained from the quantization value of the second maximum unambiguous speed is and For details, please refer to S504. The explanation will not be repeated here.

[0449] In this way, the first frequency band information, the first period information, the second frequency band information, and the second period information can maximize the least common multiple of the first value and the second value. Since the maximum speed of the speed measurement range is... Positive correlation, LCM means least common multiple operation, so this method can maximize the speed measurement range, thereby reducing or avoiding speed measurement ambiguity.

[0450] In other possible approaches, when the first frequency band information and the second frequency band information are determined, the first periodic information and the second periodic information make the least common multiple of the first value and the second value greater than a first threshold. Accordingly, when the first frequency band information and the second frequency band information are determined, the third device may select periodic information that makes the least common multiple of the first value and the second value greater than the first threshold as the first periodic information and the second periodic information.

[0451] The specific details of the first and second values ​​can be found in the explanation of the first and second values ​​above, and will not be repeated here.

[0452] Optionally, the method for determining the first threshold can be found in the description of "method for determining the first threshold" in the method shown in Figure 5. For example, it can be at least one of method a1 to method a3, which will not be elaborated further.

[0453] In this way, the first frequency band information, the first period information, the second frequency band information, and the second period information can ensure that the least common multiple of the first value and the second value is greater than the first threshold. Since the maximum speed of the speed measurement range is... The correlation is positive, therefore, this method can make the speed measurement range meet the threshold requirements, thereby reducing or avoiding speed measurement ambiguity.

[0454] In other possible approaches, the first frequency band information, the first period information, the second frequency band information, and the second period information can be selected from a configuration set; in other words, the first frequency band information, the first period information, the second frequency band information, and the second period information can be determined based on the configuration set. The specific contents of the configuration set can be found in the description of the configuration set in the method shown in Figure 5, and will not be repeated here.

[0455] For example, the configuration set is shown in Table 4A or Table 4B in the method shown in Figure 5, where each row in Table 4A or Table 4B can represent a configuration. The third device can select two rows from Table 4A or Table 4B such that the maximum speed in the speed measurement range corresponding to these two rows is [the maximum speed]. The requirements are met, thus allowing the determination of the first frequency band information, the first period information, the second frequency band information, and the second period information. For example, the third device can select two rows from Table 4A or Table 4B such that the maximum speed within the corresponding speed measurement range is obtained. Maximize; or, the third device can select two rows from Table 4A or Table 4B such that the maximum speed is within the speed measurement range corresponding to those two rows. Greater than the threshold. For details, please refer to S504 above. The explanation will not be repeated here.

[0456] For example, if the maximum speed to be measured is 100 m / s, and the first frequency band information and the first period information indicate the frequency band and period in the first row of Table 4A respectively, then the third device can select the second row of Table 4A. The first and second rows of Table 4A correspond to... In this case, the second frequency band information and the second period information can respectively indicate the frequency band and period in the second row of Table 4A; or, the third device can select the third row of Table 4A, where the first and third rows of Table 4A correspond to... In this case, the second frequency band information and the second period information can respectively indicate the frequency band and period in the third row of Table 4A.

[0457] For example, if the maximum speed to be measured is 100 m / s, and the first frequency band information and the first period information respectively indicate the frequency band and period in the first row of Table 4B, then the third device can select the second row of Table 4B, where the first and second rows of Table 4B correspond to... In this case, the second frequency band information and the second period information can respectively indicate the frequency band and period in the second row of Table 4B.

[0458] For example, if the maximum speed to be measured is 100 m / s, and the first frequency band information and the first period information respectively indicate the frequency band and period in the third row of Table 4B, then the third device can select the third row of Table 4B, and the second and third rows of Table 4B correspond to... In this case, the second frequency band information and the second period information can respectively indicate the frequency band and period in the second row of Table 4B.

[0459] As mentioned above, the maximum unambiguous velocity corresponding to the first frequency band information and the first periodic information is the first maximum unambiguous velocity; the maximum unambiguous velocity corresponding to the second frequency band information and the second periodic information is the second maximum unambiguous velocity. Optionally, the first maximum unambiguous velocity and the second maximum unambiguous velocity satisfy at least one of conditions #f1 to #f3:

[0460] Condition #f1: The difference between the first maximum unambiguous speed and the second maximum unambiguous speed is greater than the second threshold.

[0461] Condition #f2: The difference between the third quantization value and the fourth quantization value is greater than the third threshold. The third quantization value is the quantization value of the first maximum unambiguous speed, and the second quantization value is the quantization value of the second maximum unambiguous speed.

[0462] Condition #f3: The difference between the value obtained from the third quantization and the value obtained from the fourth quantization is greater than the fourth threshold.

[0463] For the specific content of conditions #f1 to #f3, please refer to conditions #b1 to #b3 respectively. The only difference is that the maximum unambiguous speed corresponding to the first configuration is replaced with the first maximum unambiguous speed, the maximum unambiguous speed corresponding to the second configuration is replaced with the second maximum unambiguous speed, the first quantization value is replaced with the third quantization value, and the second quantization value is replaced with the fourth quantization value.
