Technical Field

[0001] This application relates to the field of mobile communication technology, and in particular to a communication method and apparatus. Background Technology

[0002] Sensing technology is gradually being introduced into cellular systems to assist in cellular communication. Based on sensing technology, a device transmitting a sensing reference signal can send a sensing reference signal, and correspondingly, a receiving device can receive the echo signal of the sensing reference signal after it is reflected by the target, and obtain the sensing result based on the echo signal detection.

[0003] Currently, how to configure the sensing reference signal is a technical problem that urgently needs to be solved. Summary of the Invention

[0004] This application provides a communication method and apparatus for configuring a sensing reference signal.

[0005] Firstly, embodiments of this application provide a communication method, which can be executed by a first communication device, or in other words, the method can be applied to a first communication device. Unless otherwise specified, the "first communication device" in this application can refer to the terminal device itself, a component within the terminal device, or a logic module or software capable of implementing all or part of the terminal device's functions. The terminal device serves as a transmitting device for a first sensing reference signal. The components in this application may include, for example, at least one of a chip, chip system, processor, transceiver, processing unit, transceiver unit, or other functional modules. Taking the first communication device as the executing entity as an example, the method includes: the first communication device receiving first configuration information, the first configuration information including transmission configuration information for one or more first sensing reference signals, the first configuration information being included in a radio resource control (RRC) message or a non-access stratum (NAS) message, the transmission configuration information for the first sensing reference signal including resource configuration of the first sensing reference signal; and the first communication device transmitting the first sensing reference signal according to the transmission configuration information of the first sensing reference signal.

[0006] Based on the method described in the first aspect, the first communication device can receive transmission configuration information of the first sensing reference signal via RRC messages or NAS messages. Therefore, this method can configure the first communication device to transmit the first sensing reference signal via RRC messages or NAS messages, i.e., it supports transmitting transmission configuration information of the sensing reference signal via RRC messages or NAS messages.

[0007] In one possible implementation, the transmission configuration information of the first sensing reference signal further includes at least one of the following: first sensing mode information, which is used to indicate the relationship between the transmitting device and the receiving device of the first sensing reference signal; first indication information, which is used to indicate that the first communication device is the transmitting device of the first sensing reference signal; and a first identifier of the sensing process, which is used to indicate the sensing process to which the first sensing reference signal belongs.

[0008] Based on this implementation method, the transmission configuration information of the first sensing reference signal can include one or more of the following: sensing mode information, transmission and reception indication information (or transmitting device identifier and / or receiving device identifier), or sensing process identifier, which can realize flexible configuration of the sensing reference signal.

[0009] In one possible implementation, the first sensing mode information corresponds to at least one of the resource configuration of the first sensing reference signal, the first indication information, and the first identifier of the sensing process; or, the first indication information corresponds to at least one of the resource configuration of the first sensing reference signal, the first sensing mode information, and the first identifier of the sensing process; or, the first identifier of the sensing process corresponds to at least one of the resource configuration of the first sensing reference signal, the first sensing mode information, and the first indication information.

[0010] Based on this implementation, the first sensing mode information in the transmission configuration information of the first sensing reference signal corresponds to resource configuration, transmit / receive instruction information (or transmitting device identifier and / or receiving device identifier) ​​or sensing process identifier. This implementation allows for clustered indication of the transmission configuration information of multiple sensing reference signals, reducing the complexity of the configuration information indication. For example, when indicating the configuration information of multiple sensing reference signals, the configuration information of multiple sensing reference signals with the same sensing mode is relatively similar. Clustering indication can be performed on the sensing mode information to reduce the indication complexity. For example, one or more sensing mode information can be indicated first, followed by the resource configuration, transmit / receive instruction information, or sensing process identifier corresponding to each sensing mode information. That is, for each sensing mode information, the resource configuration, transmit / receive instruction information, or sensing process identifier corresponding to the corresponding sensing reference signal can be indicated. Similarly, clustering indication can also be performed on the transmit / receive instruction information (or transmitting device identifier and / or receiving device identifier) ​​or sensing process identifier, which will not be elaborated further.

[0011] In one possible implementation, the first configuration information further includes reception configuration information for one or more second sensing reference signals, the reception configuration information for the second sensing reference signals including resource configuration of the second sensing reference signals; the first communication device may also receive the echo signal of the second sensing reference signal according to the reception configuration information of the second sensing reference signal, and perform sensing measurement according to the echo signal of the second sensing reference signal to obtain sensing information.

[0012] Based on this implementation, the first configuration information may also include the receiving configuration information of the second sensing reference signal, so as to support the first communication device in receiving the second sensing reference signal.

[0013] In one possible implementation, the receiving configuration information of the second sensing reference signal further includes at least one of the following: second sensing mode information, which indicates the relationship between the transmitting device and the receiving device of the second sensing reference signal; second indication information, which indicates that the first communication device is the receiving device of the second sensing reference signal; and a second identifier of the sensing process, which indicates the sensing process to which the second sensing reference signal belongs.

[0014] Based on this implementation, the receiving configuration information of the second sensing reference signal can include one or more of the following: sensing mode information, transmit / receive instruction information (or transmitting device identifier and / or receiving device identifier), or sensing process identifier, which can realize flexible configuration of the sensing reference signal.

[0015] In one possible implementation, the second sensing mode information corresponds to at least one of the resource configuration of the second sensing reference signal, the second indication information, and the first identifier of the sensing process; or, the second indication information corresponds to at least one of the resource configuration of the second sensing reference signal, the second sensing mode information, and the second identifier of the sensing process; or, the second identifier of the sensing process corresponds to at least one of the resource configuration of the second sensing reference signal, the second sensing mode information, and the second indication information.

[0016] Based on this implementation method, clustering indication of the receiving configuration information of multiple sensing reference signals can be supported, reducing the indication complexity of the configuration information of multiple sensing reference signals.

[0017] In one possible implementation, the first communication device may also receive a fourth indication message, which is used to activate the transmission of the first sensing reference signal.

[0018] Based on this implementation, the first communication device can send a first sensing reference signal according to an activation instruction (i.e., the fourth instruction information). For example, the fourth instruction information can be used to indicate the periodic or non-periodic activation of the sensing reference signal transmission, and correspondingly, the first communication device can periodically or non-periodically send the sensing reference signal.

[0019] In one possible implementation, the first communication device may also receive the echo signal of the first sensing reference signal according to the resource configuration of the first sensing reference signal, and perform sensing measurement based on the echo signal of the first sensing reference signal to obtain sensing information.

[0022] Based on this implementation, for the self-transmitting and self-receiving sensing mode, the first communication device can also receive the receiving configuration information of the first sensing reference signal. The content of the receiving configuration information of the first sensing reference signal can refer to the content of the receiving configuration information of the second sensing reference signal. Optionally, the resource configuration, transmit / receive mode information, sensing mode information, and sensing process identifier in the transmit configuration information of the first sensing reference signal are the same as those in the receive configuration information of the first sensing reference signal. Therefore, flexible indication of configuration information in the self-transmitting and self-receiving sensing mode can be achieved.

[0023] In one possible implementation, the transmission configuration information of the first sensing reference signal further includes first sensing mode information, which is used to indicate a self-transmitting and self-receiving sensing mode; and / or, the transmission configuration information of the first sensing reference signal further includes first indication information, which is used to indicate that the first communication device is a transmitting device and a receiving device for the first sensing reference signal.

[0024] Based on this implementation, for the self-transmitting and self-receiving sensing mode, the transmission configuration information and reception configuration information of the first sensing reference signal can be merged into a single configuration information, eliminating the need to distinguish between them. Therefore, flexible indication of configuration information can be achieved in the self-transmitting and self-receiving sensing mode.

[0025] In one possible implementation, the first configuration information is carried in a first transmission unit, which is a transmission unit dedicated to transmitting information related to perception.

[0026] Based on this implementation, configuration information (or first configuration information) of the sensing reference signal can be carried through a dedicated transmission unit.

[0028] Based on this implementation, if carried in an RRC message, the transmission unit carrying the configuration information (or first configuration information) of the sensing reference signal can be at the same level as the transmission unit in the RRC message used to carry the SRS configuration, or the configuration information (or first configuration information) of the sensing reference signal can be combined with the SRS configuration and carried in the same transmission unit. If carried in a NAS message, the transmission unit carrying the configuration information (or first configuration information) of the sensing reference signal can be at the same level as the transmission unit in the NAS message used to carry the PRS configuration, or the configuration information (or first configuration information) of the sensing reference signal can be combined with the PRS configuration and carried in the same transmission unit.

[0030] Based on this implementation, the receiving device for the first sensing reference signal can be a third communication device, which can be a terminal device. The third communication device can receive the echo signal of the first sensing reference signal and obtain sensing information via RRC messages or NAS messages. Therefore, this method can configure the third communication device to receive the first sensing reference signal via RRC messages or NAS messages, i.e., it supports sending the receiving configuration information of the sensing reference signal via RRC messages or NAS messages.

[0031] In one possible implementation, the receiving configuration information of the first sensing reference signal further includes at least one of the following: first sensing mode information, which is used to indicate the relationship between the transmitting device and the receiving device of the first sensing reference signal; third indication information, which is used to indicate that the third communication device is the receiving device of the first sensing reference signal; and a first identifier of the sensing process, which is used to indicate the sensing process to which the first sensing reference signal belongs.

[0120] The specific implementations of this application are described below with reference to the accompanying drawings in the embodiments. However, the implementations of this application may also include combining these embodiments without departing from the spirit or scope of this application, such as using other embodiments and making structural changes. Therefore, the detailed description of the following embodiments should not be understood in a limiting sense. The terminology used in the embodiment section of this application is only used to explain the specific embodiments of this application and is not intended to limit this application.

[0121] The embodiments of this application can be applied to various communication systems, such as: long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, worldwide interoperability for microwave access (WIMAX) communication systems, 5G systems or new radio (NR) systems, or to future communication systems or other similar communication systems, or ultra-wideband (UWB) systems, or wireless fidelity (WiFi) systems.

[0122] Figure 1 A possible, non-limiting system schematic diagram is shown. For example... Figure 1 As shown, the communication system 1000 includes a wireless access network 100 and a core network 200. Optionally, the communication system 1000 may also include an Internet 300. The wireless access network 100 may include at least one wireless access network device (such as...). Figure 1 110a and 110b in the above), may also include at least one terminal (such as Figure 1(Referring to 120a-120j in the original text). Terminals connect wirelessly to the wireless access network (WLAN) equipment, which in turn connects to the core network via wireless or wired connections. The core network equipment and the WLAN equipment can be independent physical devices, or they can integrate the functions of the core network equipment and the logical functions of the WLAN equipment onto the same physical device. Alternatively, a single physical device can integrate some of the functions of both the core network equipment and the WLAN equipment. Terminals and WLAN equipment can be interconnected via wired or wireless connections. Figure 1 This is just an illustration; the communication system may also include other network devices, such as wireless repeaters and wireless backhaul devices. Figure 1 Not shown in the diagram. Unless otherwise specified, the network equipment in this application may include access network equipment and / or core network equipment.

[0123] Radio access network equipment can be a base station, an evolved NodeB (eNodeB / eNB), a transmission reception point (TRP), a transmission point (TP), a next-generation NodeB (gNB) or next-generation (NG)-eNB in ​​a 5G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. Radio access network equipment can also be open RAN (O-RAN or ORAN) equipment or cloud radio access network (CRAN) equipment. Radio access network equipment can also be a communication system integrating two or more of the above systems. Radio access network equipment can be a macro base station (such as...) Figure 1 110a in the text), can also be a micro base station or an indoor station (such as... Figure 1 110b in the context can also be a relay node or a donor node, etc.

[0124] Furthermore, the wireless access network equipment can also be a module or unit that performs some of the functions of a base station. For example, it can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. 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 O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules.

[0125] The embodiments of this application do not limit the specific technology or device form used in the wireless access network equipment. For ease of description, the wireless access network equipment will be referred to as an access network equipment below. It is understood that the access network equipment can also be called a communication device. For example, an access network equipment can be understood as a device with access network equipment functions. For example, a device with access network equipment functions can be an access network equipment, or some components in an access network equipment, such as CU, DU, etc. It can also be a device that can support the access network equipment to realize this function, such as a chip system, hardware circuit, software module, or hardware circuit plus software module. This device can be installed in the access network equipment or can be used in conjunction with the access network equipment. In the embodiments of this application, the chip system can be composed of chips or can include chips and other discrete devices.

[0126] A terminal can also be called a terminal device, user equipment (UE), mobile station, mobile terminal, etc. Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, MTC, IoT, virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, smart cities, etc. 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.

[0127] The embodiments of this application do not limit the specific technology or device form used in the terminal. It is understood that a terminal can be referred to as a communication device. For example, a terminal can be understood as a device with terminal functions. For example, a device with terminal functions can be a terminal itself; it can also be a device capable of supporting the terminal in implementing that function, such as a chip system, hardware circuit, software module, or hardware circuit plus software module. This device can be installed in a terminal or can be used in conjunction with a terminal.

[0128] Figure 2 An example diagram of an O-RAN system is shown. It should be understood that an O-RAN system may also include... Figure 3 Other components besides those shown are not specifically limited here. For example... Figure 2 As shown, access network devices can communicate with the core network (CN) via a backhaul link and with terminal devices via an air interface. For example, an access network device may include a baseband unit (BBU) and a radio unit (RU). The BBU includes at least one control unit (CU) and at least one distribution unit (DU), which can communicate via at least one midhaul link. The BBU communicates with the core network via the backhaul link, and the RU communicates with at least one terminal device via an air interface. The BBU also communicates with at least one RU via a fronthaul link. The BBU and RU may or may not be co-located.

[0129] In some examples, the CU is a logical node carrying the RRC layer, Service Data Adaptation Protocol (SDAP) layer, Packet Data Convergence Protocol (PDCP) layer, and other control functions of the access network equipment. The CU connects to network nodes such as the core network through interfaces, which can be interfaces such as E2 interfaces. Optionally, the CU may have some core network functions. The CU (e.g., PDCP layer and higher layers) connects to the DU (e.g., RLC layer and lower layers) through interfaces, which can be interfaces such as F1 interfaces. In some examples, these interfaces (e.g., F1 interfaces) can provide control plane (C-Plane) and user plane (U-Plane) functions (e.g., interface management, system information management, UE context management, RRC message transmission, etc.). F1AP is the application protocol of the F1 interface, defining the F1 signaling procedures in some examples. The F1 interface supports control plane F1-C and user plane F1-U.

[0130] In some examples, the CU can be split into CU-CP (control unit-control plane) and CU-UP (control unit-user plane). CU-CP is a logical node carrying the RRC layer and PDCP-C (control plane part of PDCP) layer, used to implement the CU's control plane functions. CU-CP can interact with network elements in the core network used to implement control plane functions. These network elements in the core network can be access and mobility function (AMF) network elements, such as the access and mobility management function (AMF) in a 5G system. The AMF network element is responsible for mobility management in the mobile network, such as terminal device location updates, terminal device registration with the network, and terminal device handover. CU-UP is a logical node carrying the SDAP layer and PDCP-U (user plane part of PDCP) layer, used to implement the CU's user plane functions. CU-UP can interact with network elements in the core network used to implement user plane functions. These network elements in the core network, such as the UPF (user plane function) in a 5G system, are responsible for data forwarding and receiving in terminal devices. The above CU and DU configurations are merely examples; the functions of the CU and DU can be configured as needed. For instance, the CU or DU can be configured to have more protocol layer functions, or only some protocol layer processing functions. For example, some RLC layer functions and protocol layer functions above the RLC layer can be placed in the CU, while the remaining RLC layer functions and protocol layer functions below the RLC layer can be placed in the DU. Furthermore, the functions of the CU or DU can be divided according to service type or other system requirements, such as by latency. Functions that require low latency can be placed in the DU, while functions that do not require low latency can be placed in the CU.

[0131] In some examples, a DU is a logical node that carries the radio link control (RLC) layer, medium access control (MAC) layer, higher physical layer (PHY) layer, and other functions. In some examples, a DU can control at least one RU. The DU connects to the RU through interfaces, which can be fronthaul interfaces. In some examples, the higher physical layer includes parts of the PHY layer processing, such as forward error correction (FEC) encoding and decoding, scrambling, modulation, and demodulation.

[0132] In some examples, the RU is a logical node that carries both lower physical layer (PHY) and radio frequency (RF) processing. In some examples, the RU can be a 3GPP transmission reception point (TRP), a remote radio head (RRH), or other similar entities. In some examples, the lower physical layer includes portions of the PHY processing, such as Fast Fourier Transform (FFT), Inverse Fast Fourier Transform (IFFT), digital beamforming, and filtering. The RU communicates with one or more UEs via a radio link.

[0133] The DU and RU may or may not be co-located. The DU and RU exchange control plane and user plane information via a fronthaul link through a lower-layer split CUS-plane (LLS-CUS) interface. LLS-CUS may include LLS-C and LLS-U interfaces that respectively provide the control plane (C-Plane) and user plane (U-Plane). In some examples, the control plane (C-Plane) refers to real-time control between the DU and RU. The DU and RU exchange management information via an LLS-M interface on the fronthaul link; the management plane (M-Plane) refers to non-real-time management operations between the DU and RU.

[0134] DU and RU can cooperate to implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of DU and RU can be configured in various ways depending on the design. For example, a DU can be configured to implement baseband functions, and an RU can be configured to implement mid-RF functions. Another example is that a DU can be configured to implement higher-level functions in the PHY layer, and an RU can be configured to implement lower-level functions in the PHY layer, or to implement both lower-level and RF functions. Higher-level functions in the physical layer can include a portion of the physical layer's functions that are closer to the MAC layer, while lower-level functions in the physical layer can include another portion of the physical layer's functions that are closer to the mid-RF side.

[0135] It is understood that the network architecture and business 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 business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0136] 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 devices, components, modules, etc. discussed in conjunction with the accompanying drawings. Furthermore, combinations of these approaches may also be used. Additionally, in the embodiments of this application, words such as "exemplarily," "for example," etc., are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as an "example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the term "example" is intended to present concepts in a concrete manner. In the embodiments of this application, "of," "corresponding / relevant," and "corresponding" may sometimes be used interchangeably, and it should be noted that their intended meanings are consistent unless their distinction is emphasized.

[0137] In this application, "transmit (Tx / tx)" and "receive (Rx / rx)" indicate the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX. "Send information" can include direct transmission or indirect transmission through other communication devices, communication apparatuses, units, or modules. "Receive information from YY" can be understood as the source of the information being YY. "Receive information" can include direct reception from YY or indirect reception from YY through other communication devices, communication apparatuses, units, or modules. Furthermore, "transmit" can also be understood as the "output" of a chip interface, and "receive" can be understood as the "input" of a chip interface. In other words, "transmit" or "receive" can occur between devices, for example, between access network devices and terminals via an air interface. "Transmit" or "receive" can also occur within a device, for example, between components, modules, chips, software modules, or hardware modules within a device via a bus, wiring, or interface.

[0138] In this application, "for indicating" can include both direct and indirect indication. When describing "information" for indicating A, it can include whether the information directly indicates A or indirectly indicates A, but does not necessarily mean that the information carries A.

[0139] The information indicated by a given piece of information is called the information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as, but not limited to, directly indicating the information to be indicated, such as the information to be indicated itself or its index. It can also be indirectly indicated by indicating other information, where there is a relationship between the other information and the information to be indicated. It can also indicate only a part of the information to be indicated, while the other parts are known or pre-agreed upon. For example, the indication of specific information can be achieved by using a pre-agreed (e.g., protocol-defined) arrangement of various pieces of information, thereby reducing the indication overhead to some extent. At the same time, common parts of various pieces of information can be identified and indicated uniformly to reduce the indication overhead caused by individually indicating the same information.

[0140] Furthermore, the specific indication method can also be any existing indication method, such as, but not limited to, the above-mentioned indication methods and their various combinations. Specific details of various indication methods can be found in existing technologies, and will not be repeated here. As described above, for example, when multiple pieces of information of the same type need to be indicated, the indication methods for different pieces of information may differ. In the specific implementation process, the required indication method can be selected according to specific needs. This application embodiment does not limit the selected indication method; therefore, the indication methods involved in this application embodiment should be understood to cover various methods that enable the party to be indicated to obtain the information to be indicated.

[0141] The information to be indicated can be sent as a whole or divided into multiple sub-information messages, and the sending period and / or timing of these sub-information messages can be the same or different. This application does not limit the specific sending method. The sending period and / or timing of these sub-information messages can be predefined, for example, according to a protocol, or configured by the transmitting device by sending configuration information to the receiving device. Taking the configuration of the UE by the access network device as an example, the configuration information can include, for example but not limited to, one or a combination of at least two of RRC signaling (or RRC messages), MAC layer signaling, and physical layer signaling. MAC layer signaling includes, for example, MAC control elements (CE). Physical layer signaling includes, for example, downlink control information (DCI) and other signaling or messages carried on the physical downlink control channel (PDCCH), and may also include downlink data (e.g., data transmitted on the physical downlink shared channel (PDSCH)).

[0142] "Preset," "predefined," or "preconfigured" can be implemented by pre-storing corresponding codes, tables, or other means of indicating relevant information in the device (e.g., including terminals and network devices), or by pre-defining them in a protocol. This application does not limit the specific implementation method. "Stored" can refer to storing in one or more memories. These memories can be separate installations or integrated into the encoder, decoder, processor, or communication device. Alternatively, some memories can be separate installations, while others are integrated into the decoder, processor, or communication device. The type of memory can be any form of storage medium, and this application does not limit this.

[0143] The following is a brief description of the technical concepts involved in this application:

[0144] 1. Perceiving the object

[0145] The sensing object can also be called the sensing target, sensing point, unit point, or reflection point, etc. In this application, the sensing object can be simply referred to as the object. The sensing object can be a static object, such as the physical environment around it, such as buildings, etc. The sensing object can also be a dynamic object, such as a drone or a car, etc., and this application does not limit it in this regard.

[0146] 2. Sensing reference signals

[0147] A sensing reference signal, also known as a sensing signal, is a signal used for sensing. It can refer to a signal transmitted by a transmitter or a signal received by a receiver (the echo signal of the transmitted signal). In this application, if there is no explicit distinction between whether there is an echo signal, the sensing reference signal can refer to either one. The sensing reference signal can be a signal whose initial amplitude and phase can be known by the receiving device (or receiver). Optionally, the sensing reference signal can be a reference signal, such as Se-RS, channel state information reference signal (CSI-RS), or SRS. The initial amplitude and phase information of the sensing reference signal can be pre-configured to the receiving device through configuration sequences, etc. The sensing reference signal can also be a data signal. The receiving device can calculate the initial amplitude and phase of each data signal through known modulation methods such as data verification. The sensing reference signal can also be any other signal whose initial amplitude and phase can be known by the receiving device. This application does not limit the presentation form of the sensing reference signal.

[0148] 3. Perception Results

[0149] The perception result, also known as perception data or perception information, or perception-related information, refers to the relevant information of the perceived object acquired by the receiving device through a perception reference signal. For example, the perception result can be a distance-angle spectrum or a point cloud. This application does not limit the specific form of the perception result.

[0150] The distance-angle spectrum refers to a two-dimensional matrix or spectrum, for example, with time delay as the horizontal axis and angle as the vertical axis, and the energy-to-interference-plus-noise ratio (SNR) ratio of each point as an element in the distance-angle spectrum.

[0151] Point clouds, or point cloud data, are datasets of points in space that can represent three-dimensional shapes or perceived objects. The position of each point in a point cloud is described by a set of Cartesian coordinates, and some may contain information such as the intensity of the object's reflective surface and its velocity.

[0152] In the fifth generation mobile communication system (the 5 th In the evolution from 5G (first generation, 5G) to 5G-advanced (5G-A) technology, 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 the ability to detect, track, and image objects, thereby integrating communication and sensing capabilities into a single network to achieve harmonious coexistence and even mutual benefit.

[0153] The technical principles of sensing differ somewhat from those of communication. Communication involves a transmitting device (or transmitter) modulating information onto radio waves and sending it to a receiving device, which then demodulates the signal to obtain the information. Sensing, however, requires a transmitting device to send radio waves in a specific direction. When these radio waves strike the surface of an object, they are reflected, and the receiving device receives and processes these reflected waves to obtain information such as the object's position, speed, and type.

[0154] Sensing can be categorized into two modes: single-site sensing and dual-site sensing. In single-site sensing, the transmitting and receiving devices for the sensing reference signal are the same device, which can be a terminal or a base station. Regarding the sensing reference signal flow, the sensing station both transmits and receives the signal reflected from the object's surface (also known as the echo signal). Therefore, single-site sensing is also called a self-transmitting and self-receiving mode. Figure 3As shown. In dual-site sensing, the transmitting and receiving devices for the sensing reference signal are two different devices, which can be either a terminal or a base station. From the perspective of the sensing reference signal flow, after sensing station A transmits the sensing reference signal, the signal reflected from the object's surface is received by sensing station B. Therefore, dual-site sensing is also called the A-transmit B-receive mode, as shown. Figure 4 As shown.

[0155] The application scenarios of this application include, but are not limited to, integrated communication and sensing scenarios. Figure 5 As shown, a possible, non-limiting integrated communication and sensing scenario is illustrated, in which access network devices and terminals (such as UE1, UE2 and UE3) in the communication network can sense objects that do not have communication functions while communicating.

[0156] like Figure 6 The diagram illustrates several possible sensing modes. Sensing mode (1) is a scenario where the base station transmits and receives signals independently; sensing mode (2) is a scenario where the UE transmits and receives signals independently; sensing mode (3) is a scenario where base station A transmits and base station B receives signals; sensing mode (4) is a scenario where UE A transmits and UE B receives signals; sensing mode (5) is a scenario where the base station transmits and the UE receives signals; and sensing mode (6) is a scenario where the UE transmits and the base station receives signals. Here, "transmit" can be understood as "transmitting a sensing reference signal," and "receive" can be understood as "receiving an echo signal." This application can be applied to one or more of these sensing modes, and can also be applied to... Figure 6 Other than the sensory modes mentioned above, this application does not specifically limit them. In this application, the sensory mode may also be simply referred to as a mode.

[0157] Among them, perception mode (1) and perception mode (2) are single-station perception, and perception modes (3) to perception mode (6) are dual-station perception.

[0158] The following is combined Figure 7 This document presents a schematic diagram of a communication system provided in an embodiment of this application. Figure 7 The illustration shows a first communication device, a second communication device, and a third communication device. The first communication device can communicate with the second and third communication devices respectively. The communication devices involved in the various embodiments of this application can be understood as devices, software or hardware modules within devices, or logic modules, etc., and are not specifically limited thereto. Furthermore, the communication device can also be replaced with a communication device, network element, device, entity, or node, etc., and its name is not specifically limited.

[0159] For example, the first communication device in this application can transmit a sensing reference signal. After being reflected, scattered, refracted, or diffracted by a target, the sensing reference signal becomes an echo signal, and sensing information can be obtained based on the echo signal. Optionally, the first communication device can also have sensing capabilities, for example, it can obtain sensing information based on the received echo signal. For example, in single-station sensing mode, the first communication device can transmit a sensing reference signal. After being reflected, scattered, refracted, or diffracted by a target, the first communication device receives the echo signal of the sensing reference signal, and then obtains sensing information based on the echo signal. Alternatively, the first communication device can also obtain sensing information based on the echo signal after receiving the echo signal of a sensing reference signal transmitted by another communication device.

[0160] Alternatively, other communication devices besides the first communication device can obtain the sensing information based on the echo signal of the sensing reference signal sent by the first communication device. For example, in a dual-station sensing mode, the first communication device in this application can send a sensing reference signal. After the sensing reference signal is reflected, scattered, refracted, or diffracted by the target, the third communication device receives the echo signal of the sensing reference signal, and then the third communication device can obtain the sensing information based on the echo signal. The first communication device can report the sensing information to the second communication device.

[0161] In this application, the first communication device is a terminal device; that is, this application mainly considers the scenario where the terminal device transmits a sensing reference signal (SenRS / Se-RS). Figure 6 Taking the perception pattern shown as an example, this application mainly considers Figure 6 The perception modes (2), (4) and (6) in the text.

[0162] Specifically, for sensing mode (2), both the transmitting and receiving devices of the sensing reference signal are first communication devices. For sensing mode (4), the transmitting device of the sensing reference signal is the first communication device, and the receiving device of the sensing reference signal is the third communication device. For sensing mode (6), the transmitting device of the sensing reference signal is the first communication device, and the receiving device of the sensing reference signal is a fourth or fifth communication device. The fourth communication device can be a base station, such as the base station accessed by the first communication device, and the fifth communication device is a base station other than the base station accessed by the first communication device.

[0163] In one possible implementation, the first communication device and / or the third communication device are terminal devices, or components of terminal devices, such as chips or chip systems disposed in terminal devices.

[0164] In another possible implementation, the second communication device is, for example, a core network element such as SMF / SF, or a component of a core network element such as SMF / SF, such as a chip or chip system disposed in a core network element such as SMF / SF.

[0165] In another possible implementation, the fourth and / or fifth communication device is, for example, an access network device, or a component of the access network device, such as a chip or chip system disposed in the access network device.

[0166] Optionally, if it is an access network device, the fourth and / or fifth communication devices may include at least one TRP, or the first communication device may be configured with or associated with at least one TRP. Different TRPs may produce different results in measuring the echo signal.

[0167] In this application, the second communication device can be used to configure the transmission of a sensing reference signal and / or the reception of an echo signal. For example, the second communication device can be used to configure the transmission resources of the sensing reference signal and / or the reception resources of the echo signal. Optionally, the second communication device may also have the ability to transmit sensing information, and may also have the ability to process (e.g., manage, control, or calculate) the sensing information.

[0168] The second communication device can be a core network element, core network functional unit, or core network entity. For example, the second communication device can be an SMF, SMM, SF, LMF (or location management communication device, or location management network element, location server, location center, location network element, location function network element, or location management function, etc.), or SMC (also called control network element, edge sensing function network element, edge control network element, or edge control node, the name of which is not limited), or a module of these network elements. Alternatively, the second communication device can also be a server (such as a third-party server) or a module of a server (such as a software module or hardware module). The embodiments of this application do not limit the specific implementation form of the second communication device.

[0169] Understandable. Figure 7In the system architecture shown, the first communication device and the second communication device can be directly connected or indirectly connected. A direct connection means that the first and second communication devices are connected via an interface or link, meaning the first communication device does not need to connect to the second communication device through other communication devices. In other words, in the case of a direct connection, information between the first and second communication devices is sent directly between them without the need for forwarding by other communication devices. An indirect connection means that the first and second communication devices are connected via other communication devices, and information sent from the first communication device to the second communication device needs to be forwarded by other communication devices, and / or information sent from the second communication device to the first communication device needs to be forwarded by other communication devices. For the indirect connection scenario… Figure 7 Other communication devices located between the first and second communication devices are not shown in the diagram, and this should not be construed as the absence of such communication devices, i.e., it should not be construed as the first and second communication devices only being able to connect directly. In this application, the communication device between the first and second communication devices can be referred to as a fourth communication device, such as a base station.

[0170] As an example of a direct connection, if the first communication device is a terminal device and the second communication device is an SMF or SF, the first communication device can communicate with the second communication device through NAS messages, and the access network device does not need to read the contents of the NAS layer messages. As an example of an indirect connection, if the first communication device is a terminal device and the second communication device is an SMF or SF, the first communication device can connect to the second communication device through a base station, in which case the base station can act as a fourth communication device. Alternatively, the base station and the SMF or SF can also be indirectly connected, for example, through other network elements or network devices such as an AMF.

[0171] Please refer to Figure 8 This is a schematic diagram of a communication system applicable to an embodiment of this application. Figure 8 It illustrates terminal equipment (such as one or more terminal devices), RAN (including one or more access network devices), and some core network elements. Figure 8 The illustrated core network elements include AMF and LMF. Figure 8 It also illustrates SMF or SF. Optionally, SMF or SF can also be deployed in the core network, that is, belong to the core network elements.

[0172] As an example, Figure 8 The illustrated terminal device can be used as an example of a first communication device, and another terminal device or access network device can be used as an example of a third communication device. Figure 8The SMF / SF involved can be used as an example of a second communication device.

[0173] Access network devices can communicate with each other via the Xn interface. The access network devices included in the access network can be of the same type, such as all gNBs or all NG-eNBs. An ng-eNB can be an LTE-compatible base station and may include one or more transport points (TRPs). A gNB is an NR base station and may include one or more transport points (TRPs). ng-eNBs and gNBs can communicate with each other via the Xn interface. Alternatively, the access network devices included in the access network can be of different types. For example, some access network devices may be ng-eNBs, and others may be gNBs.

[0174] Terminal devices communicate with the access network via Uu links. For example, a terminal device can communicate with an ng-eNB via LTE-Uu. Similarly, a terminal device can communicate with a gNB via an NR-Uu link. The access network communicates with the AMF via the NG-C interface. The AMF can be viewed as a router for communication between the access network and the LMF, and between the access network and the SMF / SF. The AMF and the LMF communicate via NLs (such as NL1) interfaces.

[0175] Optional, Figure 8 In this context, the SMF / SF and LMF can be the same network element, or in other words, the SMF / SF and LMF can be integrated together. In this case, the integration of LMF and SMF can serve as an example of a second communication device.

[0176] Optionally, the SMF / SF can include a sensing function-control plane (SF-C), or simply the control plane. The SMF / SF can also include a sensing function-user plane (SF-U), or simply the user plane. The SMF / SF can have a non-separated user plane and control plane architecture. In practical applications, the user plane and control plane of the SMF / SF can also be separated.

[0177] Figure 9 This is a schematic diagram of a communication system applicable to an embodiment of this application. For example... Figure 9 As shown, the communication system includes terminal equipment (such as one or more terminal devices), RAN (such as one or more access network devices), SMC, and SMF / SF. The details of the access network devices can be found in [reference needed]. Figure 8 The content discussed herein pertains to access network equipment. The SMC connects to the first and second access network devices via interfaces. Access network devices can also connect to different SMCs. Optionally, the SMF / SF can communicate with the SMC.

[0178] Figure 9 The illustrated terminal device can be used as an example of a first communication device, and another terminal device or access network device can be used as an example of a third communication device. Figure 9 The SMF / SF involved can be used as an example of a second communication device, or Figure 9 The SMC involved can be used as an example of a second communication device.

[0179] Figure 9 The SMF / SF shown is an example of an implementation where the user plane and control plane are not separated. In practical applications, the user plane and control plane of SMF / SF can also be separated. Similarly, the SMC can have a user plane and control plane that are not separated or separated. If the SMC is separated, then the SMC can be divided into a sensing management-control plane (SM-C) and a sensing management-user plane (SM-U). In an architecture where the user plane and control plane are not separated, SM-C can communicate with SF-C, and SM-U can communicate with SF-U.

[0180] The following example uses the first communication device as the executing entity, combined with... Figure 10 The flowchart shown illustrates the communication method provided in this application.

[0181] like Figure 10 The communication method may include the following steps:

[0182] S1001: The first communication device receives the first configuration information.

[0183] The first configuration information includes the transmission configuration of one or more first sensing reference signals. In other words, the first configuration information can be used to configure the transmission of one or more sensing reference signals.

[0184] In this application, the configuration information of the sensing reference signal may include a transmission configuration and / or a reception configuration. The transmitting device of the sensing reference signal can transmit the sensing reference signal according to the transmission configuration, and the receiving device of the sensing reference signal can receive the echo signal of the sensing reference signal according to the reception configuration. The configuration information of the sensing reference signal can be queried, determined, or configured by the access network device (such as a fourth communication device). The fourth communication device can query, determine, or configure this configuration information according to a request from a second communication device, as will be discussed below. Figure 16 The process shown will be explained in detail here.

[0185] In S1001, the transmission configuration information of the first sensing reference signal may include the resource configuration of the first sensing reference signal, which can be used to determine the time-frequency resources for transmitting the first sensing reference signal.

[0186] In S1001, the first configuration information is included in the RRC message or NAS message, and the transmission configuration information of the first sensing reference signal includes the resource configuration of the first sensing reference signal. That is, the first configuration information can be obtained from the transmission configuration of the sensing reference signal in the RRC message or NAS message.

[0187] It is understandable that the RRC message is sent by a fourth communication device, which can be an access network device such as a base station, or a module or chip within the access network device. The fourth communication device can be an access network device to which the first communication device is connected.

[0188] The NAS message can be sent by a second communication device, which can be a core network element. A core network element could be, for example, an SMF / SF. This NAS message can be sent by the second communication device and forwarded to the first communication device by an access network device connected to it.

[0189] The following describes the configuration information of the sensing reference signal. The sensing reference signal here may include a first sensing reference signal and / or a second sensing reference signal, or other sensing reference signals involved in this application, without specific limitation.

[0190] In this application, the configuration information of the sensing reference signal may include one or more of the following: resource configuration of the sensing reference signal, sensing mode information, transceiver mode information, or sensing process identifier (transaction ID).

[0191] The following sections will introduce resource configuration, sensing mode information, sending and receiving mode information, and sensing process identifiers.

[0192] A1. Resource configuration, also known as time-frequency configuration, can be used to indicate or configure the time-frequency resources of a sensing reference signal. These time-frequency resources can be the transmitting and / or receiving resources of the sensing reference signal. It can be assumed that the transmitting device of the sensing reference signal can transmit the signal according to the resource configuration, and / or, the receiving device of the sensing reference signal can receive the signal according to the resource configuration.

[0193] Specifically, resource configuration can include frequency configuration and time configuration. Frequency configuration includes parameters such as sub-carrier spacing (SCS), cyclic prefix (CP), bandwidth, frequency start position, or frequency hopping configuration for the sensing reference signal. Time configuration includes parameters such as time-domain start position, duration, or period.

[0194] A2. Sensing mode information can be used to indicate or configure the sensing mode corresponding to the sensing reference signal. The sensing mode can be used to identify the relationship between the transmitting and receiving devices of the sensing reference signal, such as whether the transmitting and receiving devices are the same device, or whether the transmitting and / or receiving devices are terminal devices or base stations. Specifically, the sensing mode can be... Figure 6 Any of the patterns shown can also be other patterns; there are no specific limitations.

[0195] As an example, the perception mode information can take any value from 1 to 3. The perception mode information can be indicated by enumeration, index, or bitstring.

[0196] For example, the enumeration indicator could be: the perception mode information value is "mode1" to "mode3", representing perception modes 1 to 3 respectively. Similarly, the index indicator could be: the perception mode information value is "Index1" to "Index3", representing perception modes 1 to 3 respectively. And the bit string indicator could be: the perception mode information value is 00, 01, and 10, representing perception modes 1 to 3 respectively.

[0197] It can be understood that modes 1 to 3 can respectively represent Figure 6 One of the following perception modes: (2), (4), or (6). For example, modes 1 through 3 represent perception modes (2), (4), and (6), respectively.

[0198] It can also be understood that the first configuration information may indicate the configuration information of the sensing reference signals for multiple sensing modes of the first communication device. Therefore, the first configuration information may additionally indicate the sensing modes for the configuration information of the sensing reference signals.

[0199] A3. Transmit / receive mode information, also known as device function information, can be used to indicate or configure the configuration information of the sensing reference signal as either transmit or receive configuration information. If the configuration information is transmit configuration information, the corresponding communication device receiving the configuration information can transmit the sensing reference signal according to that configuration information. If the configuration information is receive configuration information, the corresponding communication device receiving the configuration information can receive the echo signal of the sensing reference signal according to that configuration information.

[0200] One way to implement transmit / receive mode information is to use a first value to represent sending and a second value to represent receiving. The first and second values ​​can occupy the same field, cell, or bit (or bit string). For example, transmit / receive mode information occupies 1 bit, where the first value representing sending can be 0 and the second value representing receiving can be 1, or the first value can be 1 and the second value can be 0.

[0201] In addition, the transmit / receive mode information may include the identifier of the receiving device and / or the identifier of the transmitting device, to indicate the receiving device and / or transmitting device to which the configuration information applies.

[0202] For example, transmit / receive mode information can be a combination of transmit / receive indication and device identifier (device-id). For instance, the transmit / receive indication can be a first value or a second value, where the first value represents sending and the second value represents receiving, respectively. The identifier can be, for example, the identifier of the terminal device. For instance, (0, device-id#1) represents the identifier of the sending device as device-id#1, and (1, device-id#2) represents the identifier of the receiving device as device-id#2.

[0203] For example, the identifier of the transmitting device (denoted as txdevice-id) and the identifier of the receiving device (denoted as rxdevice-id) can appear in pairs. For instance, (txdevice-id#1, rxdevice-id#1) and (txdevice-id#2, rxdevice-id#2) represent that the identifier of the transmitting device for sensing reference signal #1 is txdevice-id#1, and the identifier of the transmitting device for sensing reference signal #2 is rxdevice-id#2.

[0204] In addition, in the above example, the device identifier can also be represented by an index. For example, index 1 represents device-id#1. The mapping relationship between the index and the device identifier can be pre-configured. For example, this mapping relationship can be broadcast by the base station through a broadcast message, and the terminal device can learn the index corresponding to the device identifier through the broadcast message.

[0205] For example, taking a first sensing reference signal as an example, the transmission configuration information of the first sensing reference signal may include first indication information in the transmission mode information, used to indicate that the first communication device is the transmitting device of the first sensing reference signal. For example, the first indication information includes the identifier of the transmitting device, which is the device identifier of the first communication device. As another example, if the first configuration information also includes configuration information for a second sensing reference signal, taking the second sensing reference signal as an example, the transmission mode information may include second indication information, used to indicate that the first communication device is the receiving device, indicating that the second sensing reference signal is a sensing reference signal transmitted by the first communication device. As yet another example, in the receiving configuration information of the first sensing reference signal, the transmission mode information may include third indication information, which can be used to indicate that one or more of the first, third, or fourth communication devices are the receiving devices of the first sensing reference signal.

[0206] Optionally, if the first configuration information includes configuration information for multiple sensing reference signals, the first configuration information may carry the transmission and reception mode information of the configuration information for multiple sensing reference signals through enumeration or bitmap.

[0207] For example, the first configuration information can be the Sensing Reference Signal Configuration (SenRS-Config). Specifically, for the receiving configuration information, SenRS-Config can be SenRS-ConfigRx, and correspondingly, the first transmission unit can be configured as SenRS-ConfigRx. For the transmitting configuration information, SenRS-Config can be SenRS-ConfigTx, and correspondingly, the first transmission unit can be configured as SenRS-ConfigTx. An exemplary pseudocode for enumerating the transmit / receive mode information of the Sensing Reference Signal in SenRS-Config is shown below:

[0208]

[0209] A4. Sensing process identifier, used to indicate the sensing process to which the sensing reference signal belongs. For example, a communication device can determine the sensing process to which the configuration information applies based on the sensing process identifier. Different sensing process identifiers correspond to different sensing processes. For the same terminal device, the configuration information can be different under different sensing processes.

[0210] As an example, any sensing process identifier may correspond to one or more pairs of transmitting and receiving devices, or to one or more sensing reference signals of one or more pairs of transmitting and receiving devices. Alternatively, any sensing process identifier may be considered to correspond to a certain range of time-domain resources and / or frequency-domain resources.

[0211] For example, if the first configuration information includes configuration information for a first sensing reference signal, then the first configuration information may include a first identifier, which is an identifier of the sensing process to which the first sensing reference signal belongs. Similarly, if the first configuration information also includes configuration information for a second sensing reference signal, then the first configuration information may include a second identifier, which is an identifier of the sensing process to which the second sensing reference signal belongs.

[0212] A5. In addition to A1 to A4, the configuration information of any sensing reference signal may also include one or more of the following parameters:

[0213] (1) Frequency layer

[0214] The frequency layer can be used to indicate the frequency layer corresponding to the sensing reference signal. For example, the frequency layer transmission can be an identifier, spectral information, or index of the frequency layer corresponding to the sensing reference signal.

[0215] In this application, if the same information, message, or information element contains configuration information for multiple sensing reference signals, the frequency layers of the multiple sensing reference signals can be indicated by enumerating the identifiers of the frequency layers or by using a bitmap or other schemes.

[0216] Optionally, the configuration information may not include frequency layer parameters; instead, the frequency layer may be indicated through other messages or signaling. For example, the frequency may be pre-configured or defined.

[0217] (2) TRP information

[0218] TRP information can be used to indicate the TRP corresponding to the sensing reference signal. For example, TRP information can be an identifier or index of the TRP corresponding to the sensing reference signal.

[0219] In this application, if the same information, message, or information element contains configuration information for multiple sensing reference signals, the TRP information of the multiple sensing reference signals can be indicated by enumerating the identifiers of the frequency layers or by using a bitmap or other schemes.

[0220] Optionally, the configuration information may not include TRP information; instead, TRP information may be indicated through other messages or signaling. For example, the TRP information may be pre-configured or pre-defined.

[0221] (3) Resource mapping configuration, such as parameters including the number of persistent symbols, frequency interval, or quasi-coordinated-location (QCL) information.

[0222] Optionally, resource mapping configuration can also be considered as a type of resource configuration.

[0223] (4) Transmission combination configuration, which can be used to configure the frequency domain resource combination method.

[0224] For example, the transmission combination configuration includes the parameter frequency interval (transmissionComb). For example, transmissionComb = n, where n is a positive integer, such as n = 2, 4, 6, 8... TransmissionComb is used to indicate the density of the sensing reference signal, i.e., the frequency interval, that is, the sensing reference signal is transmitted once every n subcarriers.

[0225] For example, the transmission combination configuration includes the parameter subcarrier offset (combOffset). combOffset is a positive integer less than or equal to n-1, where n is the frequency interval. For instance, if n=2 and combOffset=0, it means the sensing reference signal is mapped on the first subcarrier, and a sensing reference signal is transmitted every two subcarriers after the first subcarrier; if n=2 and combOffset=1, it means the sensing reference signal is mapped on the second subcarrier, and a sensing reference signal is transmitted every two subcarriers after the second subcarrier.

[0226] For example, transmission combination configurations include parameter cyclic shift.

[0227] (5) Antenna and spatial configuration, including parameters such as port index (PortIndex) and spatial relationship information (spatialRelationInf).

[0228] Optionally, the configuration information of the sensing reference signal can be carried in the SenRS Configuration (SenRS-Config) message or information cell.

[0229] It is understood that at least two of the resource configuration, sensing mode information, transmit / receive mode information, and sensing process identifier in the configuration information of the first sensing reference signal can be carried in the same or different transmission units or sub-transmission units, without specific limitations.

[0230] It can also be understood that, for the same sensing reference signal, the TRP information in the transmit configuration information can be different from the TRP information in the receive configuration information, while other configurations in the transmit and receive configuration information can be the same. For example, the resource configuration in the transmit configuration information and the resource configuration in the receive configuration information of the same sensing reference signal can be the same.

[0231] S1002: The first communication device transmits the first sensing reference signal according to the transmission configuration information of the first sensing reference signal.

[0232] The first sensing reference signal can be used to obtain sensing results. For example, a receiving device for the first sensing reference signal can receive the echo signal of the first sensing reference signal and obtain sensing results by detecting the echo signal. In this application, the receiving device for the first sensing reference signal can receive the echo signal according to the receiving configuration information of the first sensing reference signal. The receiving configuration information of the first sensing reference signal may include the resource configuration of the first sensing reference signal, which can be used to determine the time-frequency resources for receiving the echo signal.

[0233] based on Figure 10 As shown in the process, the terminal device can receive the transmission configuration information of the sensing reference signal through RRC messages or NAS messages, and send the sensing reference signal according to the transmission configuration information of the sensing reference signal.

[0234] The following is combined Figures 11A to 11D The implementation of the receiving device for the first sensing reference signal is introduced.

[0235] like Figure 11A As shown, as one possible sensing mode, the receiving device of the first sensing reference signal can be a first communication device, such as when the sensing mode is... Figure 6 The sensing mode (2) is a self-transmitting and self-receiving mode of the terminal device. In this mode, the first communication device can also receive the receiving configuration information of the first sensing reference signal, and receive the echo signal of the first sensing reference signal according to the receiving configuration information, and perform measurements based on the echo signal to obtain sensing information. The receiving configuration information of the first sensing reference signal can be carried in the first configuration information along with the transmitting configuration information, or they can be carried in different information, messages, or IEs; this application does not specifically limit this. In the self-transmitting and self-receiving mode, the transmitting configuration information and the receiving configuration information of the sensing reference signal can also be combined into the configuration information of the sensing reference signal.

[0236] Optionally, for sensing mode (2), i.e., the self-transmitting and self-receiving sensing mode, the transmission configuration information and reception configuration information of the first sensing reference signal can be independent, for example, carried by two independent information, information elements, or messages. As an example, the transmission configuration information and reception configuration information of the first sensing reference signal can be carried by different information elements in the first configuration information.

[0237] The transmission configuration information and reception configuration information of the first sensing reference signal can also be combined as the configuration information of the first sensing reference signal. For example, the transmission configuration information and reception configuration information are carried through the same cell. At this time, the first configuration information in S1001 can include the configuration information of the first sensing reference signal, which includes transmission configuration information and reception configuration information. The configuration information of the first sensing reference signal can include first sensing mode information, which can be used to indicate the self-transmitting and self-receiving sensing mode. For example, the sensing mode indicated by the first sensing mode information is sensing mode (2). In addition, the configuration information of the first sensing reference signal can also include first indication information, which is used to indicate that the first communication device is the transmitting device and receiving device of the first sensing reference signal.

[0238] like Figure 11B As shown, as another possible sensing mode, the receiving device of the first sensing reference signal can be a third communication device, which can be another terminal device. In this case, the sensing mode is as follows: Figure 6 The perception mode in (4).

[0239] In this example, the third communication device can receive the reception configuration information of the first sensing reference signal and receive the echo signal according to the reception configuration information. Referring to the transmission configuration information of the first sensing reference signal in S1001, the reception configuration information of the first sensing reference signal can be carried in an RRC message or via a NAS message. If the reception configuration information of the first sensing reference signal can be carried in an RRC message, the RRC message can be sent by a fourth communication device or other access network equipment. If the reception configuration information of the first sensing reference signal is carried in a NAS message, the NAS message can be sent by a second communication device.

[0240] like Figure 11C As shown, as another possible sensing mode, the receiving device of the first sensing reference signal can be an access network device such as a base station. This access network device can be a fourth communication device. The sensing mode in this case is, for example... Figure 6 The sensing mode (6) in the middle. Among them, the transmission configuration information and / or reception configuration information of the first sensing reference signal can be determined or configured by the fourth communication device. That is, when the fourth communication device is the receiving device of the first sensing reference signal, the fourth communication device knows the reception configuration information of the first sensing reference signal and the fourth communication device does not need to receive the reception configuration information of the first sensing reference signal separately.

[0241] In addition, such as Figure 11D As shown, in another possible sensing mode, where the terminal device sends a sensing reference signal and the access network device receives the echo signal, the access network device can also be a fifth communication device. The second or fourth communication device can send the reception configuration information of the first sensing reference signal to the fifth communication device. For example, if there is an inter-base station interface between the fourth and fifth communication devices, the fourth communication device can send the reception configuration information of the first sensing reference signal to the fifth communication device through the inter-base station interface.

[0242] It is understandable that multiple communication devices, including the first, third, fourth, or fifth communication devices, may receive echo signals of the same first sensing reference signal and obtain sensing information by measuring the echo signals.

[0243] The possible structures of the configuration information for the first configuration information and / or the first sensing reference signal are described below.

[0244] In this application, the configuration information of the first sensing reference signal can be carried in the first transmission unit, that is, the configuration information of the first sensing reference signal can be transmitted through the first transmission unit. This first transmission unit can be carried in an RRC message or a NAS message. The first transmission unit can be understood as the transmission unit in the RRC message used to carry the first configuration information, or as the transmission unit in the NAS message used to carry the first configuration information. The transmission unit in the RRC message used to carry the first configuration information and the transmission unit in the NAS message used to carry the first configuration information are deployed in the same message.

[0245] The RRC message can be sent from the fourth communication device to the first communication device, and the NAS message can be sent from the second communication device to the first communication device. The first transmission unit can be considered as the first configuration information. Alternatively, the first transmission unit can be considered as a transmission unit containing the first configuration information; that is, it is not limited whether the first transmission unit carries information other than the first configuration information.

[0246] The first transmission unit can be a transmission unit used to transmit sensing-related information. Alternatively, the first transmission unit can be described as a transmission unit dedicated to transmitting sensing-related information. Specifically, sensing-related information can also be called sensing information, specifically sensing-related configuration information. Sensing-related configuration information can also be called sensing configuration information, such as configuration information for sensing reference signals or other configuration information. That is, the first transmission unit can be a transmission unit dedicated to transmitting sensing information, or in other words, the first transmission unit is dedicated to providing sensing information (or sensing-related information). The first transmission unit can be, for example, a message providing sensing information, or a sensing information cell. Alternatively, the first transmission unit can be a transmission unit dedicated to transmitting configuration information for sensing reference signals (or other sensing-related configuration information), or in other words, the first transmission unit is dedicated to providing sensing reference signal configuration (or sensing-related configuration). The first transmission unit is, for example, a message or information element that provides configuration for the sensing reference signal, such as a ProvideSenRSConfiguration message or ProvideSenRSConfiguration IE. Specifically, for receiving configuration information, ProvideSenRSConfiguration can be ProvideSenRSConfigurationRx, and correspondingly, the first transmission unit can be ProvideSenRSConfigurationRx IE. For sending configuration information, ProvideSenRSConfiguration can be ProvideSenRSConfigurationTx, and correspondingly, the first transmission unit can be ProvideSenRSConfigurationTx IE.

[0247] In one possible implementation, if the first configuration information is carried in an RRC message, then the first configuration information can be SenRS-Config, and the first transmission unit can be a SenRS-Config IE. If the first configuration information is carried in a NAS message, then the first configuration information can be ProvideSenRSConfiguration, and the first transmission unit can be ProvideSenRSConfiguration IE.

[0248] In this application, when a communication device (such as a second or fourth communication device) transmits sensing information, it by default uses a first transmission unit to transmit sensing information such as configuration information carrying a sensing reference signal. For example, the first transmission unit can be a predefined or pre-configured unit specifically for transmitting sensing-related information. For instance, the first transmission unit can be a transmission unit predefined by a protocol specifically for transmitting sensing information or configuration information of a sensing reference signal. The configuration information of the first sensing reference signal discussed above can be considered a specific example of sensing information (or configuration information of a sensing reference signal).

[0249] In one possible implementation, for example Figure 12 As shown in Figure (1), the configuration information (or first transmission unit) of a first sensing reference signal may include SenRSConfiguration configuration, sensing mode configuration, and device identification configuration. The SenRSConfiguration configuration can be used to carry resource configurations for the sensing reference signal. The sensing mode configuration can be used to carry sensing mode information. The device identification configuration can be used to carry transmit / receive mode information, such as the identifier of the transmitting device and / or the identifier of the receiving device. Optionally, the configuration information (or first transmission unit) of the first sensing reference signal may also include one or more configurations for carrying parameters such as sensing process identifiers, which are not shown in the figure.

[0250] Specifically, the SenRSConfiguration configuration may contain one or more sub-units or sub-configurations such as the SenRSConfigurationPerFreq configuration, the SenRSConfigurationPerTRP configuration, or the SenRSConfigurationSet-Item configuration. The SenRSConfigurationPerFreq configuration can be used to indicate the frequency layer to which the first sensing reference signal applies; the SenRSConfigurationPerTRP configuration can be used to indicate the TRP to which the first sensing reference signal applies; and the SenRSConfigurationSet-Item configuration is used for the carry-on resource configuration to which the first sensing reference signal applies.

[0251] based on Figure 12 (1) As shown in the structure, the configuration information of multiple first sensing reference signals can be carried in multiple different transmission units. Each transmission unit can carry the SenRSConfiguration configuration, sensing mode configuration and device identifier configuration corresponding to a first sensing reference signal.

[0252] In another possible implementation, such as Figure 12As shown in (2), the configuration information of the first sensing reference signal can be carried in the SenRS-Config configuration. SenRS-Config can be SenRS-ConfigTx or SenRS-ConfigRx.

[0253] like Figure 12 As shown, the SenRS-ConfigTx configuration can include SenRS-ResourceSet configurations. A SenRS-ResourceSet configuration can contain one or more SenRS-Resource configurations, and any SenRS-Resource configuration can be used to configure the configuration information of a single SenRS-Resource. The configuration information of the first SenRS-Resource may also include the frequency layer configuration and / or TRP information for each SenRS-Resource.

[0254] It can be considered that the SenRS-ResourceSet configuration can be used to indicate the configuration information of one or more sensing reference signals as the configuration information of the sensing reference signals in this configuration from the configuration information of one or more sensing reference signals in one or more SenRS-Resource configurations.

[0255] As an example, the SenRS-Resource configuration can include configuration information at the granularity of the sensing reference signal resources. For instance, the SenRS-Resource configuration may include the resource identifier (SenRS-ResourceID), resource type (resourceType), time-frequency domain configuration, parameter combination configuration, or antenna and spatial configuration of the sensing reference signal.

[0256] The resource identifier can be used to mark the configuration information of each sensing reference signal. The resource type can be used to indicate the resource type of the configuration information of each sensing reference signal. Specifically, the resource type can indicate whether the configuration information of the sensing reference signal is periodic, semi-periodic, or aperiodic.

[0257] The SenRS-ResourceSet configuration can include the SenRS-ResourceSet ID configuration, the resourceSet Type configuration, and the SenRS-ResourceIdList configuration, which lists the identifiers of the SenRS-ResourceSet resources contained in the SenRS-ResourceSet.

[0258] The SenRS-ResourceSet identifier can be used to identify a SenRS-ResourceSet configuration. The resource set type can be used to indicate whether the resource set type is a periodic configuration, an aperiodic configuration, or a semi-periodic configuration. The list or index of identifiers for SenRS-Resources can contain one or more SenRS-ResourceIDs to indicate the configuration information of one or more SenRS-Resources.

[0259] based on Figure 12 The pseudocode for an exemplary SenRS-ConfigTx configuration, as shown in Figure (2), is as follows:

[0260]

[0261] In another possible implementation, the configuration information (or the first transmission unit) of the first sensing reference signal can be ProvideSenRSConfiguration IE. Specifically, ProvideSenRSConfiguration IE can be ProvideSenRSConfigurationRx IE or ProvideSenRSConfigurationTx IE.

[0262] Optionally, ProvideSenRSConfiguration IE can use Figure 12 The structure shown in (1) is as follows. For example, ProvideSenRSConfiguration IE contains Figure 12 The SenRSConfiguration configuration, sensing mode configuration, and device identification configuration shown in (1) are as follows.

[0263] Alternatively, ProvideSenRSConfiguration can also be used in IE. Figure 12 The structure shown in (3) is as follows. For example, the ProvideSenRSConfiguration IE can contain SenRS-AssistanceData configuration and Selected-SenRS-IndexList configuration.

[0264] The SenRS-AssistanceData configuration can include configuration information for multiple sensing reference signals, such as reference signal configurations for multiple frequency layers and multiple TRPs, frequency configurations, time configurations, resource mapping configurations, and sensing reference signal identifiers.

[0265] Correspondingly, the Selected-SenRS-IndexList configuration can include the configuration of selected reference signals, such as by carrying the selected frequency layer index, selected TRP index, selected resource index, etc., indicating the configuration information of one or more selected sensing reference signals in the SenRS-AssistanceData configuration. The resource index can be, for example, a resource index (ResourceIndex), a resource identifier (ResourceID), a resource set index (ResourceSetIndex), or a resource set identifier (ResourceSetID).

[0266] Based on this implementation, different time-frequency resources with different frequencies and different TRPs can be configured through the auxiliary data configuration of the sensing reference signal. The resource configuration of one or more sensing reference signals can be selected from the selected sensing reference signal index list to indicate whether to send or receive signals in the resource corresponding to the resource configuration.

[0267] based on Figure 12 The pseudocode for an exemplary ProvideSenRSConfiguration IE, as shown in section (3), is as follows:

[0268]

[0269] In the pseudocode above, SenRS-AssistanceData can be used to define specific time-frequency resources, such as the location, period, resource mapping method, and resource identifier of time-frequency resources with different frequency layers and different TRPs, as shown below:

[0270]

[0271] Additionally, in the pseudocode above, Selected-SenRS-IndexList can be used to indicate on which defined resource the sensing reference signal is transmitted and received. It can include parameters such as the frequency layer, TRP, or resource identifier of the selected time-frequency resource. For example, Selected-SenRS-IndexList can be implemented using the following pseudocode:

[0272]

[0273] For example, when configuring the sensing reference signal's configuration information via NAS messages, the sensing reference signal's configuration information can carry transmit / receive mode information. See the pseudocode below; the DeviceFunction, i.e., the transmit / receive mode information, can be additionally indicated in ProvideSenRSConfiguration.

[0274]

[0275] It is understandable that if the configuration information of the first sensing reference signal is carried in the RRC message, the configuration information of the first sensing reference signal may include... Figure 12 The structure shown in (2) is as follows. If the configuration information of the first sensing reference signal is carried in the NAS message, the configuration information of the first sensing reference signal may include... Figure 12 The structure shown in (1) or (3) is shown in the middle.

[0276] In one possible embodiment, the configuration information of the sensing reference signal can be carried in the same RRC message or the same NAS message as the configuration information of other types of reference signals. These other types of reference signals include, for example, PRS, SRS, or CSI-RS, and are not specifically limited. The configuration information of the sensing reference signal here can include a first sensing reference signal or other sensing reference signals.

[0277] This can be understood as the transmission configuration information of the sensing reference signal possibly being carried in the same RRC message as the SRS configuration (SRS-Config). For example, the transmission configuration information of the first sensing reference signal and / or the transmission configuration information of the second sensing reference signal may be carried in the same RRC message as the SRS-Config.

[0278] The reception configuration information for the sensing reference signal may be carried in the same RRC message as the CSI-RS configuration. The CSI-RS configuration may be the CSI-MeasConfig. For example, the transmission configuration information for the first sensing reference signal and / or the reception configuration information for the second sensing reference signal may be carried in the same RRC message as the CSI-MeasConfig.

[0279] Additionally, the initial configuration information may be carried in the same NAS message as the PRS configuration.

[0280] Taking SenRS-ConfigTx as an example of the transmission configuration information for the first sensing reference signal, if SenRS-ConfigTx and SRS-Config are carried in the same RRC message, then SenRS-ConfigTx and SRS-Config can satisfy the following positional relationship:

[0281] Positional relationship B1, embedded: In the RRC message, the first transmission unit used to carry SenRS-ConfigTx is embedded in the second transmission unit used to carry SRS-Config, such as... Figure 13As shown in section (1). Accordingly, the fourth communication device can send SRS-Config to the first communication device, which may contain SenRS-ConfigTx. Positional relationship B1 can also be described as follows: SenRS-ConfigTx is contained in a sub-transmission unit of SRS-Config. The second transmission unit can be considered as a transmission unit dedicated to transmitting SRS-Config.

[0282] The first transmission unit is, for example, SenRS-ConfigTx IE, and the second transmission unit is, for example, SRS-Config IE.

[0283] Positional relationship B2, parallel: In the RRC message, the first transmission unit used to carry SenRS-ConfigTx and the second transmission unit used to carry SRS-Config are located in two parallel transmission units, such as... Figure 13 As shown in number (2). Accordingly, the fourth communication device can send SRS-Config and SenRS-ConfigTx to the first communication device. Positional relationship B2 can also be described as follows: SenRS-ConfigTx and SRS-Config are two transmission units at the same level, which do not contain each other, and these two transmission units are located in the same IE or message or information.

[0284] The first transmission unit is, for example, SenRS-ConfigTx IE, and the second transmission unit is, for example, SRS-Config IE.

[0285] Positional relationship B3, combination: In RRC messages, SenRS-ConfigTx and SRS-Config can be carried in the same transmission unit (such as being called a third transmission unit), or in other words, SenRS-ConfigTx and SRS-Config can be combined into a single transmission unit, such as... Figure 13 As shown in number (3). It can be assumed that SenRS-ConfigTx and / or SRS-Config are carried in a sub-transmission unit of the third transmission unit. Accordingly, the fourth communication device can send the third transmission unit, which contains SenRS-ConfigTx and SRS-Config, to the first communication device. Figure 13 In this context, the third transmission unit is exemplarily represented as ISACRS-Config IE, but it may also have other names.

[0286] Similarly, the receiving configuration information for the first sensing reference signal is SenRS-ConfigRx, and the relationship between SenRS-ConfigRx and CSI-MeasConfig can be embedded, parallel, or combined. (Refer to...) Figure 13 When the reception configuration information for the first sensing reference signal is SenRS-ConfigRx, it can be... Figure 13 The replacement of SenRS-ConfigTx with SenRS-ConfigRx and SRS-Config with CSI-MeasConfig is not elaborated further.

[0287] In one possible embodiment, the NAS message may carry ProvideSenRSConfigurationTx and / or ProvideSenRSConfigurationRx configurations. The ProvideSenRSConfigurationTx configuration can be used to carry transmission configuration information for a sensing reference signal (such as a first sensing reference signal), and the ProvideSenRSConfigurationRx configuration can be used to carry reception configuration information for a sensing reference signal (such as the first sensing reference signal). The first configuration information may include the ProvideSenRSConfigurationTx carried in the ProvideSenRSConfigurationTx configuration and / or the ProvideSenRSConfigurationRx carried in the ProvideSenRSConfigurationRx configuration. Furthermore, the NAS message may also carry ProvideAssistanceData configuration. The ProvideAssistanceData configuration can be used to carry PRS configurations, as defined in the LTE positioning protocol (LPP).

[0288] The ProvideSenRSConfigurationTx configuration and / or ProvideSenRSConfigurationRx configuration and ProvideAssistanceData configuration can satisfy the following positional relationship:

[0289] Location relationship C1, embedded: In the NAS message, the ProvideSenRSConfigurationTx configuration and / or ProvideSenRSConfigurationRx configuration are embedded in the ProvideAssistanceData configuration, such as... Figure 14As shown in section (1). Accordingly, the fourth communication device can send ProvideAssistanceData configuration to the first communication device, which may include ProvideSenRSConfigurationTx configuration and / or ProvideSenRSConfigurationRx configuration. Positional relationship C1 can also be described as: ProvideSenRSConfigurationTx configuration and / or ProvideSenRSConfigurationRx configuration as sub-transmission units of ProvideAssistanceData configuration.

[0290] Positional relationship C2, parallel: In NAS messages, ProvideSenRSConfigurationTx configuration and / or ProvideSenRSConfigurationRx configuration and ProvideAssistanceData configuration are located in two parallel transmission units, such as... Figure 14 As shown in number (2). Accordingly, the fourth communication device can send ProvideAssistanceData configuration, and ProvideSenRSConfigurationTx configuration and / or ProvideSenRSConfigurationRx configuration to the first communication device. The positional relationship C2 can also be described as follows: ProvideAssistanceData configuration and ProvideSenRSConfigurationTx configuration and / or ProvideSenRSConfigurationRx configuration are transmission units of the same level, which do not contain each other and are located in the same IE or message or information.

[0291] Location Relationship C3, Combination: In NAS messages, ProvideAssistanceData configuration, ProvideSenRSConfigurationTx configuration, and / or ProvideSenRSConfigurationRx configuration can be carried in the same transmission unit (e.g., referred to as the third transmission unit). In other words, ProvideAssistanceData configuration, ProvideSenRSConfigurationTx configuration, and / or ProvideSenRSConfigurationRx configuration can be combined into a single transmission unit. Figure 14As shown in section (3), the ProvideAssistanceData configuration, ProvideSenRSConfigurationTx configuration, and / or ProvideSenRSConfigurationRx configuration can be considered to be carried in a sub-transmission unit of the third transmission unit. Accordingly, the fourth communication device can send the third transmission unit to the first communication device, which contains the ProvideAssistanceData configuration, ProvideSenRSConfigurationTx configuration, and / or ProvideSenRSConfigurationRx configuration. Figure 13 In this context, the third transmission unit is exemplarily represented as ProvideISACAAssistanceData configuration, but the third transmission unit may also have other names.

[0292] The ProvideSenRSConfigurationTx and / or ProvideSenRSConfigurationRx configurations mentioned above can be considered as the first transmission unit in the NAS message used to carry configuration information for the sensing reference signal. The ProvideAssistanceData configuration can be considered as the second transmission unit in the NAS message dedicated to carrying the PRS configuration.

[0293] As an example of the positional relationship C3, the ProvideISACAAssistanceData containing the ProvideSenRSConfigurationRx configuration and the ProvideAssistanceData configuration can be ProvideAssistData-r9-IEs, which can be implemented using the following pseudocode:

[0294]

[0295] In one possible embodiment, the first configuration information may include, in addition to transmission configuration information for one or more first sensing reference signals, reception configuration information for one or more sensing reference signals. These one or more sensing reference signals may include one or more first sensing reference signals and / or one or more second sensing reference signals. That is, transmission configuration information and reception configuration information for the same sensing reference signal may be carried in the same information, message, or cell.

[0296] For example, in a self-transmitting and self-receiving scenario, if the first configuration information includes the transmission configuration information of the first sensing reference signal and the reception configuration information of the second sensing reference signal, the first communication device can transmit the first sensing reference signal according to the transmission configuration information of the first sensing reference signal, and can also receive the echo signal of the first sensing reference signal according to the reception configuration information of the first sensing reference signal, and detect the echo signal to obtain the sensing result.

[0297] In addition, the transmission configuration information and reception configuration information of multiple different sensing reference signals can be carried in the same information, message or cell.

[0298] For example, if the first configuration information includes transmission configuration information for the first sensing reference signal and reception configuration information for the second sensing reference signal, the first communication device can transmit the first sensing reference signal according to the transmission configuration information for the first sensing reference signal, and can also receive the echo signal of the second sensing reference signal according to the reception configuration information for the second sensing reference signal, and detect the echo signal to obtain the sensing result.

[0299] When the first configuration information includes configuration information for multiple sensing reference signals, the configuration information for multiple sensing reference signals can be clustered according to at least one of sensing mode information, transceiver mode information, or sensing process information. That is, the first configuration information can include configuration information clustered according to at least one of sensing mode information, transceiver mode information, or sensing process information.

[0300] It is understood that if clustering is performed using sensing mode information, then there is a correspondence between the sensing mode information and at least one of the resource configuration, transmission and reception mode information, and sensing process information of the sensing reference signal configuration information in the first configuration information. That is, the sensing mode information corresponds to at least one of the resource configuration, transmission and reception mode information, or sensing process information of the sensing reference signal configuration information.

[0301] As an example, the perception mode information and the corresponding transmit / receive mode information and / or other configuration information can be carried in different fields of the first configuration information, such as in transmission units at the same or different levels.

[0302] For example, when configuring the sensing reference signal configuration information via RRC messages, refer to the pseudocode below. The SenRS-Config field first indicates that the sensing mode information's value (mode) ranges from 1 to maxModes. Then, the SenRS-ConfigPerMode field indicates the transmit / receive mode information and / or resource configuration information corresponding to any sensing mode information. Here, sensingMode represents the sensing mode information, and DeviceFunction represents the transmit / receive mode information.

[0303]

[0304] For example, when configuring the sensing reference signal configuration information via NAS messages, refer to the pseudocode below. The ProvideSenRSConfiguration field first indicates that the sensing mode information's value (mode) is from 1 to maxModes. Then, the ProvideSenRSConfigurationPerMode field indicates the transmit / receive mode information and / or resource configuration information corresponding to any sensing mode information. Here, the ProvideSenRSConfigurationTx field is, for example, ProvideSenRSConfigurationTx configuration and / or ProvideSenRSConfigurationRx configuration, sensingMode represents the sensing mode information, and DeviceFunction represents the transmit / receive mode information.

[0305]

[0306] Similarly, if the transmit / receive mode information is used for clustering, then there is a correspondence between the transmit / receive mode information and at least one of the resource configuration, perception mode information, and perception process information of the configuration information of the perception reference signal in the first configuration information. That is, the transmit / receive mode information corresponds to at least one of the resource configuration, perception mode information, or perception process information of the configuration information of the perception reference signal.

[0307] For example, the transmission unit first indicates the transmission mode information, such as indicating at least one of the transmission modes: sending, receiving, or receiving and sending. Then, the sub-transmission unit indicates the sensing mode information and / or resource configuration information corresponding to any of the transmission mode information.

[0308] In one possible embodiment, the first communication device may transmit a first sensing reference signal according to fourth indication information. That is, the fourth indication information can be used to activate the transmission of the first sensing reference signal. For example, the fourth indication information is an activation indication.

[0309] In this application, the fourth instruction information may be carried in an RRC message or a NAS message, or in other messages, such as MAC layer signaling or DCI, without specific limitations.

[0310] Specifically, if carried in an RRC message, the RRC message may be sent from a fourth communication device to a first communication device. The NAS message may be sent from a second communication device to a first communication device. Alternatively, the fourth instruction information in this application may be sent from a second or fourth communication device to a first communication device.

[0311] It is understood that the RRC message carrying the fourth indication information can be the same as or different from the RRC message carrying the first configuration information. Similarly, the NAS message carrying the fourth indication information can be the same as or different from the NAS message carrying the first configuration information. Furthermore, if the first configuration information is carried in an RRC message, the fourth indication information can be carried in either an RRC message or a NAS message. If the first configuration information is carried in a NAS message, the fourth indication information can be carried in either an RRC message or a NAS message.

[0312] It can also be understood that the fourth instruction information can be included in the first instruction information, or the first instruction information can be included in the fourth instruction information. Furthermore, the first instruction information and the fourth instruction information can also be two pieces of information within the same message hierarchy.

[0313] Specifically, the fourth indication information can be triggered and sent by the second or fourth communication device, that is, the activation of the first sensing reference signal is determined by the second or fourth communication device.

[0314] like Figure 15 As shown, when the fourth instruction information is triggered by the second communication device, such as Figure 15 As shown in (1), the second communication device can send a fourth instruction message to the first communication device via NAS message.

[0315] In addition, such as Figure 15 As shown in (2), when the second communication device triggers the transmission of the fourth indication information, the second communication device can also send a first request information to the fourth communication device. This first request information can be used to request or instruct the fourth communication device to send the fourth indication information. Accordingly, the fourth communication device can send the fourth indication information via an RRC message after receiving the first request information. Optionally, the fourth communication device can also send a first response information to the second communication device to indicate the transmission result of the fourth indication information.

[0316] As an example, the first request information can be a UE sensingactivation request (UE sensingactivation Req), and the first response information can be a UE sensingactivation response (UE sensingactivation Res).

[0317] like Figure 15As shown in (3), when the fourth communication device triggers the transmission of the fourth indication information, the fourth communication device can send the fourth indication information to the first communication device via RRC message, MAC layer signaling, or DCI. Optionally, in this example, the fourth communication device can also send the first configuration information to the first communication device, which includes the transmission configuration information of the first sensing reference signal.

[0318] The following section describes the content of the fourth instruction message in conjunction with the activation mode.

[0319] In this application, the activation mode of the sensing reference signal can include semi-periodic activation and aperiodic activation. In semi-periodic activation, the fourth indication information can be used to indicate the activation period and the activation time of the sensing reference signal, and optionally, it can also indicate the activation duration. The terminal device can periodically activate the transmission of the sensing reference signal according to the period. The activation duration can be used to indicate the duration of each transmission of the sensing reference signal.

[0320] In non-periodic activation, the fourth indication information can be used to indicate the activation time of the sensing reference signal, and optionally, the activation duration. The terminal device can activate the transmission of the sensing reference signal according to the activation time. The activation duration can be used to indicate the duration of transmitting the sensing reference signal.

[0321] The following is combined Figure 16 This application describes a method by which a fourth communication device determines the configuration information of a first sensing reference signal. In this application, the fourth communication device can determine the configuration information of the first sensing reference signal based on a request from a second communication device.

[0322] like Figure 16 As shown, the second communication device can send a second request message to the fourth communication device. This second request message requests configuration information for one or more first sensing reference signals. The second request message can be referred to as a Terminal Equipment Sensing Reference Signal Configuration Request (UESenRSConfigurationRequest). Upon receiving the second request message, the fourth communication device can query, determine, or generate configuration information for one or more first sensing reference signals. This configuration information includes sending configuration information and / or receiving configuration information. Additionally, the fourth communication device can also send a second response message to the second communication device, which may contain configuration information for one or more first sensing reference signals.

[0323] Specifically, the second request information may include one or more of the following: resource requirement information, sensing mode information, transmitting device information, receiving device information, or identification of the sensing process for one or more first sensing reference signals. The resource requirement information, sensing mode information, transmitting device information, receiving device information, or identification of the sensing process may be a requirement for each first sensing reference signal, and the fourth communication device may determine the configuration information for each first sensing reference signal based on this requirement.

[0324] The resource requirement information may include frequency requirement information and / or time requirement information. Frequency requirement information may indicate the frequency range of the first sensing reference signal, such as including bandwidth or frequency start position. Time requirement information may indicate the time range of the first sensing reference signal, such as including time start position, duration, or period. Additionally, the resource requirement information may also include resource mapping configurations, such as the number of resource duration symbols, frequency interval, or QCL information.

[0325] When the second request information is used to request configuration information for multiple sensing reference signals, the resource requirement information may also include one or more frequency layers and / or TRP information. For example, a frequency layer corresponds to the requirement information for one or more resources, meaning the second request information may include the requirement information for resources at one or more frequency layers. Similarly, TRP information corresponds to the requirement information for one or more resources, meaning the second request information may include the requirement information for resources at one or more TRP levels.

[0326] The sensing mode information can be the same as the sensing mode information in the configuration information of the first sensing reference signal.

[0327] The information of the transmitting device can be used to indicate the transmitting device of the first sensing reference signal. For example, the information of the transmitting device includes an identifier of the transmitting device of the first sensing reference signal. In this application, the transmitting device is a first communication device for the first sensing reference signal.

[0328] The information of the receiving device can be used to indicate the receiving device of the first sensing reference signal. For example, the information of the receiving device includes an identifier of the receiving device of the first sensing reference signal. In this application, the receiving device for the first sensing reference signal can be a first communication device.

[0329] The identifier of the sensing process can be used to indicate the sensing process corresponding to the first sensing reference signal, and can be the same as the sensing mode information in the configuration information of the first sensing reference signal.

[0330] In one possible embodiment, based on the fourth communication device receiving the second request information sent by the second communication device and sending the second response information to the second communication device, the second communication device and / or the fourth communication device may send configuration information of the sensing reference signal to one or more transmitting and / or receiving devices of the first sensing reference signal.

[0331] like Figures 17A to 17D As shown, taking the first communication device as an example of a transmitting device for one or more first sensing reference signals, combined with... Figure 10 The scene shown can be accessed through Figures 17A to 17D The process shown enables the transmission of configuration information for the sensing reference signal.

[0332] like Figure 17A As shown, in a scenario where the first communication device acts as a transmitter of one or more first sensing reference signals, and the fourth communication device acts as a receiver of one or more first sensing reference signals, after the fourth communication device determines the configuration information of one or more sensing reference signals based on the second request information of the second communication device, the fourth communication device can send second response information to the second communication device, and can also send first configuration information to the first communication device via an RRC message. The first configuration information may include transmission configuration information for one or more first sensing reference signals. Additionally, the fourth communication device can receive echo signals according to the reception configuration information of one or more first sensing reference signals. Specifically, the fourth communication device can determine the transmission configuration information and / or reception configuration information of one or more first sensing reference signals based on the second request information.

[0333] Understandable. Figure 17A The order in which the fourth communication device sends the RRC message carrying the first configuration information and the second response information is not restricted.

[0334] like Figure 17BAs shown, in a scenario where a first communication device acts as a transmitter of one or more first sensing reference signals, and a third communication device acts as a receiver of one or more first sensing reference signals, where the first and third communication devices are different terminal devices, after the fourth communication device determines the configuration information of the first sensing reference signals based on the second request message from the second communication device, it can send second response information to the second communication device. The fourth communication device can also send first configuration information to the first communication device via an RRC message. The first configuration information may carry transmission configuration information for one or more first sensing reference signals. The fourth communication device can also send second configuration information to the third communication device via an RRC message, which may carry reception configuration information for one or more first sensing reference signals. The fourth communication device can determine the transmission configuration information and / or reception configuration information for one or more first sensing reference signals based on the second request information.

[0335] Understandable. Figure 17B The order in which the fourth communication device sends the RRC message carrying the first configuration information, the RRC message carrying the second configuration information, and the second response information is not restricted.

[0336] like Figure 17C As shown, in a scenario where the first communication device acts as both a transmitter and receiver of one or more first sensing reference signals (i.e., a self-transmitting and self-receiving scenario), after the fourth communication device determines the configuration information of the first sensing reference signal based on the second request message from the second communication device, it can send a second response message to the second communication device. The fourth communication device can also send first configuration information to the first communication device via an RRC message, which may carry configuration information for one or more first sensing reference signals. This configuration information may include transmission configuration information and reception configuration information. Specifically, the fourth communication device can determine the transmission configuration information and / or reception configuration information for one or more first sensing reference signals based on the second request message.

[0337] Understandable. Figure 17C The order in which the fourth communication device sends the RRC message carrying the first configuration information and the second response information is not restricted.

[0338] like Figure 17CAs shown, in a scenario where the first communication device acts as a transmitter of one or more first sensing reference signals, and the fifth communication device acts as a receiver of one or more first sensing reference signals, where the first and fifth communication devices are different base stations, after the fourth communication device sends a second response message to the second communication device based on the second request message from the second communication device, the fourth communication device sends first configuration information to the first communication device via an RRC message, which may carry transmission configuration information for one or more first sensing reference signals. Additionally, the fourth communication device sends reception configuration information for the first sensing reference signals to the fifth communication device via the inter-base station interface, enabling the fifth communication device to receive the echo signal of the first sensing reference signals according to the reception configuration information. The fourth communication device can determine the transmission configuration information and / or reception configuration information for one or more first sensing reference signals based on the second request message.

[0339] Understandable. Figure 17C The order in which the fourth communication device sends the RRC message carrying the first configuration information, the message carrying the second configuration information, and the second response information is not restricted.

[0340] Understandably, 17A to Figure 17D The following explanation uses the example of a fourth communication device providing configuration information for a sensing reference signal to a first communication device. For the implementation where a second communication device provides configuration information for a sensing reference signal to a first and / or third communication device via a NAS message, the second communication device can provide the configuration information for the sensing reference signal to the first communication device via a NAS message after receiving the second response information of the second request information.

[0341] For example, it can be Figure 17A The first configuration information shown, sent from the fourth communication device to the first communication device, can be replaced with the first configuration information sent from the second communication device to the first communication device. For example, it can be... Figure 17B The first configuration information sent from the fourth communication device to the first communication device is replaced with the first configuration information sent from the second communication device to the first communication device, and the second configuration information sent from the fourth communication device to the third communication device is replaced with the second configuration information sent from the second communication device to the third communication device. For example, it can be... Figure 17C The first configuration information sent from the fourth communication device to the first communication device shown is replaced with the first configuration information sent from the second communication device to the first communication device.

[0342] The following is combined Figure 18 This section describes the possible structure of the second request information.

[0343] like Figure 18As shown, the second request information may include the requested UE SenRS Transmission Characteristics configuration. Figure 18 In this context, UESenRSConfigurationRequest indicates the message containing the second request information (such as a NAS message) or IE.

[0344] The requestedUESenRSTransmissionCharacteristics configuration can contain resource requirements information for one or more sensing reference signals.

[0345] Additionally, the second request information may also include sensingMode configuration and Device-ID configuration. The sensingMode configuration can be used to carry the sensing mode information in the second request information, and the Device-ID configuration can be used to carry the identification identifier. Furthermore, the second request information may also include configuration for carrying the sensing process identifier, or the sensing process identifier may be carried within the second request information itself.

[0346] The following pseudocode could be an example of a second request message containing the requestedUESenRSTransmissionCharacteristics configuration, sensingMode configuration, and Device-ID configuration:

[0347]

[0348] In one possible embodiment, the second response information corresponding to the second request information can be called the sensing reference signal configuration response information (UESenRSConfigurationResponse).

[0349] The second response information may include configuration information for one or more sensing reference signals. The configuration information for these one or more sensing reference signals includes the configuration information for the first sensing reference signal.

[0350] Specifically, the second response information may include one or more of the following: resource configuration of one or more first sensing reference signals, sensing mode information, information of the transmitting device, information of the receiving device, or identifier of the sensing process.

[0351] The resource configuration of the first sensing reference signal can be referred to the description of the resource configuration of the first sensing reference signal in the first configuration information, and will not be repeated here. The resource configuration of the first sensing reference signal can be understood as the specific time-frequency resource configuration of the sensing reference signal obtained based on the resource demand information of the sensing reference signal in the second request information. For example, the frequency configuration of the first sensing reference signal in the second response information can be determined according to the frequency range in the resource demand information of the sensing reference signal in the second request information. Similarly, the time configuration of the first sensing reference signal in the second response information can be determined according to the time range in the resource demand information of the sensing reference signal in the second request information. In addition, the resource configuration of the first sensing reference signal may also include resource mapping configuration, such as the number of resource duration symbols, frequency interval, or QCL information. The resource mapping configuration may be the same as or different from the resource mapping configuration in the resource demand information, without specific limitations.

[0352] The sensing mode information, transmitting device information, receiving device information, and sensing process identifier can be identical to the sensing mode information, transmitting device information, receiving device information, and sensing process identifier in the second request information. Therefore, it can be understood that the fourth communication device can provide or provide feedback on the resource configuration of the corresponding sensing reference signal to the second communication device based on one or more of the resource requirement information, sensing mode information, transmitting device information, receiving device information, and sensing process identifier in the second request information.

[0353] The following is combined Figure 19 Introduce the possible structures of the second response information.

[0354] like Figure 19 As shown, the second response information may contain SenRSConfiguration configuration. UESenRSConfigurationResponse represents the message containing the second response information (such as a NAS message) or IE.

[0355] The SenRSConfiguration configuration may contain resource configurations for one or more sensing reference signals. Specifically, the SenRSConfiguration configuration may contain one or more sub-units or sub-configurations such as SenRSConfigurationPerFreq, SenRSConfigurationPerTRP, or SenRSConfiguration-Item. Specifically, SenRSConfigurationPerFreq can be used to indicate the frequency layer to which the first sensing reference signal applies, and this frequency layer may be included in the frequency layer indicated in the second request information; SenRSConfigurationPerTRP can be used to indicate the TRP information to which the first sensing reference signal applies, and this frequency layer may be included in the TRP information indicated in the second request information; SenRSConfiguration-Item is used for the carry resource configuration to which the first sensing reference signal applies.

[0356] Additionally, the second response information may also include sensingMode configuration and Device-ID configuration. The sensingMode configuration can be used to carry sensing mode information, and the Device-ID configuration can be used to carry identification identifiers. Furthermore, the second response information may also include configurations for carrying sensing process identifiers, or the sensing process identifier may be carried within the second response information itself.

[0357] The following is an example of pseudocode for the second response message:

[0358]

[0359] In one possible embodiment, the second request information can be used to request configuration information for multiple sensing reference signals, wherein the multiple sensing reference signals may include a first sensing reference signal. Correspondingly, the second response information may include configuration information for the multiple sensing reference signals.

[0360] Specifically, the plurality of sensing reference signals may correspond to a plurality of sensing reference signal transmitting devices, and / or to a plurality of sensing reference signal receiving devices. The plurality of sensing reference signals may include a first sensing reference signal, a second sensing reference signal, or other sensing reference signals.

[0361] For example, the transmitting device for the first sensing reference signal can be a first communication device, and the receiving device can be a first communication device, a fourth communication device, a third communication device, or other communication devices. Other communication devices may be terminal devices other than the first or third communication device, or base stations or access network devices other than the fourth communication device.

[0362] For example, for the second sensing reference signal, its transmitting device can be a fourth communication device, a third communication device, or other communication device, and its receiving device can be a first communication device.

[0363] When the second request information is used to request configuration information for multiple sensing reference signals, the second request information may include one or more of the following: resource requirement information for the multiple sensing reference signals, sensing mode information, information of the transmitting device, information of the receiving device, or identifiers of the sensing process. Correspondingly, the second response information may include configuration information for the multiple sensing reference signals.

[0364] The following describes how the second request information requests configuration information for multiple sensing reference signals, and how the second response information feeds back configuration information for multiple sensing reference signals.

[0365] In method D1, the second request information may indicate one or more parameters such as resource requirement information, sensing mode information, transmitting device information, or receiving device information, depending on the different sensing process identifiers. Similarly, if the second response information contains configuration information for multiple sensing reference signals, the second response information may indicate one or more parameters such as resource configuration and sensing mode information, transmitting device information, or receiving device information, depending on the different sensing process identifiers.

[0366] For example, UESenRSConfigurationRequest and UESenRSConfigurationResponse can carry different Transaction IDs and their corresponding parameters.

[0367] For example, the configurations such as transactionIDSet, txDeviceIdSet, rxDeviceIdSet, and requestedUESenRSTransmissionCharacteristicsSet in UESenRSConfigurationRequest and UESenRSConfigurationResponse can carry parameters corresponding to different Transaction IDs, as shown in the following pseudocode:

[0368]

[0369] For example, the UESenRSConfigurationRequest carries the configuration corresponding to different Transaction IDs in the form of a terminal device sensing reference signal configuration request per sensing process (UESenRSConfigurationRequestPerTransaction), as shown in the following pseudocode:

[0370]

[0371] It is understood that if the fourth communication device determines multiple sensing reference signals based on the second request message, then the fourth communication device or the second communication device can respectively send configuration information of the multiple sensing reference signals to the transmitting and / or receiving devices of the multiple sensing reference signals. For example... Figure 20 As shown, taking a sensing mode where multiple sensing reference signals are sent by a terminal device and received by a fourth communication device as an example, if the sending device for sensing reference signal #1 is terminal device #1 and the sending device for sensing reference signal #2 is terminal device #2, configuration information for multiple sensing reference signals can be requested through the same sensing request information (as shown in the second request information in the figure), and configuration information for multiple sensing reference signals can be fed back through the same response information (as shown in the second response information in the figure). Additionally, the second communication device can send the transmission configuration information for sensing reference signal #1 to terminal device #1 and the transmission configuration information for sensing reference signal #2 to terminal device #2. This configuration method can be applied in sensing scenarios where the fourth communication device receives the echo signal of sensing reference signal #1 and the echo signal of sensing reference signal #2, and can also be applied to other sensing scenarios without specific limitations.

[0372] In addition, the fourth communication device can also send the transmission configuration information of the sensing reference signal #1 to the terminal device #1, and send the transmission configuration information of the sensing reference signal #2 to the terminal device #2.

[0373] In method D2, the second request information may indicate one or more of the following parameters for different sending and receiving device pairs: resource demand information, sensing mode information, sending device information, or receiving device information.

[0374] The sending and receiving device pair in the second request information can be indicated by enumeration or by a bitmap. The pseudocode for an example enumeration method is shown below:

[0375]

[0376] Alternatively, the sending device can be configured first in the second request information, and then the receiving device and one or more parameters such as resource requirements, sensing mode or sensing process identifier can be configured for each sending device.

[0377] As a pseudocode implementation, in the following pseudocode, the second request information can first indicate the sending device in the sending device configuration set through the txDeviceIdSet field, and then indicate the receiving device and corresponding parameter configuration corresponding to the sending device in the sending device configuration set through the requested UESenRSTransmissionCharacteristicsTxSet field:

[0378]

[0379] Alternatively, the receiving device can be configured first in the second request information, and then the sending device, resource requirements, sensing mode, or sensing process identifier can be configured for each receiving device.

[0380] Similarly, in the second response information of the second request information, the sending device can be configured first, and then the receiving device, resource configuration, perception mode or perception process identifier, etc. can be configured for each sending device.

[0381] As a pseudocode implementation, in the following pseudocode, the second response information can first indicate the sending device in the sending device configuration set through the txDeviceIdSet field, and then indicate the receiving device and corresponding parameter configuration corresponding to the sending device in the sending device configuration set through the SenRSConfigurationTxSet field:

[0382]

[0383] As an example of bitmap indication, if the sending devices are UE1 and UE2, and the receiving devices are BS1, BS2, and UE3, the bitmap can be represented as follows: In this bitmap, each row corresponds to a transmitting device, and each column corresponds to a receiving device. A value of 0 indicates that the corresponding transmitting and receiving device pair is not activated, while a value of 1 indicates that the corresponding transmitting and receiving device pair is activated. Activation means that the second request information is used to request the configuration information of the transmitting and receiving devices for the applicable sensing reference signal. Conversely, inactivation means that the second request information does not request the configuration information of the transmitting and receiving devices for the applicable sensing reference signal. Therefore, it can be considered that this bitmap can indicate the following four pairs of transmitting and receiving devices: (1) UE1-BS1, (2) UE1-UE3, (3) UE2-BS2, and (4) UE2-UE3.

[0384] The pseudocode for an exemplary bitmap indication method is shown below:

[0385]

[0386] In method D3, the second request information may indicate one or more of the following parameters for different sensing modes: resource requirement information, information of the sending device, information of the receiving device, and sensing process identifier. Similarly, if the second response information contains configuration information for multiple sensing reference signals, then the second response information may indicate one or more of the following parameters for different sensing modes: resource configuration, information of the sending device, information of the receiving device, and sensing process identifier.

[0387] For example, UESenRSConfigurationRequest and UESenRSConfigurationResponse can carry information on different sensing modes and corresponding reference signal configurations.

[0388] For example, the UESenRSConfigurationRequest first indicates the sensing modes in the sensing mode set, and then specifies parameters such as resource requirements, sending device, receiving device, or sensing process identifier for each sensing mode.

[0389] It is understood that any combination of methods D1, D2, and D3 above can be implemented.

[0390] For example, method D3 can be further combined with method D1.

[0391] As an example of combining mode D3 and mode D1, UESenRSConfigurationRequest and UESenRSConfigurationResponse can carry reference signal configurations corresponding to different sensing mode information and sensing process identifiers. This application does not impose specific restrictions on the hierarchical relationship between the sensing mode information and the sensing process identifiers.

[0392] For example, in the UESenRSConfigurationRequest, the sensing modes in the sensing mode set can be indicated first through the Terminal Device Sensing Reference Signal Configuration Request Sensing Mode Set field (UESenRSConfigurationRequestModeSet), and then the resource requirements, sensing process identifier, and other parameters corresponding to each sensing mode can be indicated through the Terminal Device Sensing Reference Signal Configuration Request PerMode field. Specifically, the UESenRSConfigurationRequestPerMode field can first indicate that the sensing process identifier has a value from 1 to maxTransaction, and then indicate parameters such as the sending device, receiving device, and resource requirements for each sensing process identifier. As shown in the following pseudocode:

[0393]

[0394] As another example of combining method D3 and method D1, in UESenRSConfigurationRequest, the sensing process set in the terminal device sensing reference signal configuration request (UESenRSConfigurationRequestTransactionSet) field can first indicate the sensing process in the sensing process set, and then the per sensing process field in the terminal device sensing reference signal configuration request (UESenRSConfigurationRequestPerTransaction) field can indicate the resource requirements, sensing mode, and other parameters corresponding to each sensing process. The UESenRSConfigurationRequestPerTransaction field can further indicate the sensing mode value from 1 to maxMode, and then indicate the sending device, receiving device, and resource requirements for each sensing mode value. As shown in the following pseudocode:

[0395]

[0396] For example, in method D3, it can be further combined with method D2 to implement the second request information and / or the second response information. For instance, in the pseudocode above, the UESenRSConfigurationRequestPerMode field can also indicate the sending device, and then indicate parameters such as the receiving device, resource requirements, or sensing process identifier for each sending device; or, the UESenRSConfigurationRequestPerMode field can also indicate the receiving device, and then indicate parameters such as the sending device and resource requirements for each receiving device.

[0397] Similarly, this application can also combine mode D1, mode D2 and mode D3 to send a second request message and / or second response information, the implementation of which will not be described in detail.

[0398] In actual communication, the sensing task (or sensing function) may be related to the positioning task (or positioning function). For example, the positioning task (or positioning function) may be part of the sensing task (or sensing function), or the positioning task (or positioning function) may be relatively independent of the sensing task (or sensing function), but the two can assist each other. To facilitate the transmission of the configuration information of the first sensing reference signal and the information related to the positioning task (hereinafter referred to as positioning information), in one possible implementation, the first transmission unit is associated with (or related to) the transmission unit used to carry the positioning information.

[0399] In one possible embodiment, the second request information can be carried in the same NAS message as the positioning information request. The positioning information request can be used to request configuration information related to positioning services, such as positioning-related reference signal configurations. As described in this application, positioning-related reference signals are, for example, PRS, SRS, or CSI-RS. Specifically, the positioning-related reference signal configuration can be request information or response information for requesting the configuration of the aforementioned positioning-related reference signals. Taking SRS as an example, the positioning information request can be used to request SRS configuration, as defined in the NR positioning protocol A (NRPPa).

[0400] The second request information and the location information request can satisfy the following location relationship:

[0401] Location relationship E1, embedded: In the NAS message, the second request information is embedded within the location information request, or in other words, the second request information is contained within the location information request. For example, the second request information can serve as a sub-transmission unit of a transmission unit carrying the location information request. The transmission unit carrying the second request information can be called the fourth transmission unit, and the transmission unit carrying the location information request can be called the sixth transmission unit. The fourth transmission unit can serve as a sub-transmission unit of the sixth transmission unit. Figure 21 As shown in number (1), UESenRSConfigurationRequest represents the second request message, and PositioningInformationRequest represents the location information request. The location relationship E1 can also be described as: UESenRSConfigurationRequest is a sub-transmission unit of PositioningInformationRequest.

[0402] Location relationship E2, parallel: In the NAS message, the second request information and the location information request are located in two parallel transmission units, such as... Figure 21 As shown in section (2). The transmission unit used to carry the UESenRSConfigurationRequest can be called the fourth transmission unit, and the transmission unit used to carry the PositioningInformationRequest can be called the fifth transmission unit. The fourth and fifth transmission units are two parallel transmission units. The positional relationship E2 can also be described as follows: PositioningInformationRequest and UESenRSConfigurationRequest are transmission units of the same level; these transmission units do not contain each other and are located within the same IE.

[0403] Location relationship E3, combination: In the NAS message, the second request information and the location information request can be carried in the same transmission unit. This transmission unit is a transmission unit that combines the second request information and the location information request. For example, this transmission unit is... Figure 21The ISACRSConfigurationRequest is shown as number (3). For example, the transmission unit used to carry the UESenRSConfigurationRequest can be called the fourth transmission unit, and the transmission unit used to carry the PositioningInformationRequest can be called the fifth transmission unit. The fourth and fifth transmission units are two sub-transmission units in the ISACRSConfigurationRequest. It can also be said that the second request information and the positioning information request can be combined into one transmission unit, such as Figure 21 As shown in number (3).

[0404] Similarly, the second response information can be carried in the same NAS message as the positioning information response. The positioning information response can carry configuration information related to positioning services, such as positioning reference signal configuration. Taking SRS as an example, the positioning information response can be used by the fourth communication device to feed back the SRS configuration to the second communication device, see the definition in NRPPa.

[0405] like Figure 21 As shown, UESenRSConfigurationResponse represents the second response information, and PositioningInformationResponse represents the location information response. Figure 21 As shown in number (1), the second response information can be embedded in the location information response, or in other words, the seventh transmission unit used to carry the second response information can be a sub-transmission unit of the ninth transmission unit, which can also be used to carry the location information response. Figure 21 As shown in number (2), the seventh transmission unit for carrying the second response information and the eighth transmission unit for carrying the positioning information response can be carried in two parallel transmission units. Figure 21 As shown in number (3), the second response information and the location information response can be carried in the same transmission unit.

[0406] As an example where UESenRSConfigurationRequest is embedded within PositioningInformationRequest, and UESenRSConfigurationRequest is embedded within PositioningInformationResponse, the NAS message can be implemented using the following pseudocode:

[0407]

[0408] As an example where UESenRSConfigurationRequest and PositioningInformationRequest are located in two parallel transmission units, and UESenRSConfigurationRequest and PositioningInformationResponse are located in two parallel transmission units, the NAS message can be implemented using the following pseudocode:

[0409]

[0410] As an example where the UESenRSConfigurationRequest and PositioningInformationRequest are located in a combined transport unit, and the UESenRSConfigurationRequest and PositioningInformationResponse are located in a combined transport unit, the NAS message can be implemented using the following pseudocode:

[0411]
