"At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b, or c can mean: a, b, c, a and b, a and c, b and c, or a and b and c. Among them, a, b, and c can be single or multiple.

[0097] With the rapid development of wireless communication technology, base stations, as core network components, are experiencing a continuous expansion in their functions and application scenarios. In recent years, technologies that utilize base stations for environmental awareness have gained increasing attention. This technology, based on the interaction between base stations and their surroundings, collects and analyzes signals received by base stations to achieve environmental awareness and monitoring.

[0098] In the field of environmental perception, traditional methods typically rely on specialized sensors and equipment, such as cameras, radars, or infrared detectors. However, these methods have several challenges, such as high cost, difficult deployment, and susceptibility to weather conditions. In contrast, utilizing base stations for environmental perception offers numerous advantages.

[0099] Base stations have extensive coverage. As the infrastructure of wireless communication networks, base stations typically cover entire cities or specific areas. This means that environmental sensing using base stations can enable real-time monitoring of large areas, providing valuable data support for urban planning, traffic management, disaster warning, and other fields. Secondly, base stations are always online. Base stations are required to provide communication services to users 24 hours a day, so they are always operational. This allows environmental sensing using base stations to achieve real-time, continuous data collection and analysis, enabling timely identification and resolution of environmental issues. Furthermore, using base stations for environmental sensing can reduce costs. Since base stations are already widely deployed in cities, there is no need to install a large number of additional sensors and equipment. Simply upgrading and renovating existing base stations can enable environmental sensing and monitoring. This not only saves significant investment costs but also avoids duplication of construction and waste of resources.

[0100] When using base stations for sensing, there is a problem of limited coverage. The base station can only effectively sense and detect strong reflective targets within the visible area. Figure 1As shown in Figure 1, for a base station, the sensing area is divided into line-of-sight (LOS) and non-line-of-sight (NLOS) areas. Due to the obstruction of obstacles, it is impossible to effectively sense the target in the NLOS area. For the NLOS area, terminal equipment can be introduced to assist the base station in sensing. For example, Figure 2 As shown, the terminal device assists the base station in achieving environmental perception. Specifically, the base station transmits a sensing reference signal, which is reflected by a reflector and then by a cylinder to the terminal device. The terminal device measures the sensing reference signal and obtains a sensing measurement result. Both the reflector and the cylinder can be considered sensing targets. If there are multiple sensing targets to be detected, different beams are used to transmit the sensing reference signal to improve target detection accuracy.

[0101] When using a base station for environmental perception, if there are multiple sensing targets, or if there are multiple propagation paths, determining the propagation path between the terminal device and the base station is a question worth considering. Furthermore, the terminal device needs to transmit sensing reference signals via multiple beams, so how to configure sensing reference signal resources for the terminal device is also a question worth considering.

[0102] This application provides a corresponding technical solution to enable access network equipment or perception management functions to obtain propagation path information between terminal devices and access network equipment, which is conducive to the access network equipment or perception management functions to accurately perceive the environment and improve perception accuracy. For details, please refer to the detailed description of the embodiments below.

[0103] The following introduces the communication system to which this application is applicable. This application is still applicable to other communication systems and is not specifically limited in this application.

[0104] Figure 3A This is a schematic diagram of the communication system of the embodiment of the present application. Figure 3A The communication system includes a terminal device 301, a next generation Node B (gNB) 302, a next generation evolved Node B (ng-eNB) 303, an access and mobility management function (AMF) 304, a location management function (LMF) 305 and a sensing management function (SMF) 306.

[0105] The terminal device 301 communicates with the access network device (such as Figure 3A The ng-eNB303 is an access network device in the long term evolution (LTE) communication system, and the gNB302 is an access network device in the new radio (NR) communication system. In this communication system, access network devices communicate with each other through the Xn interface, and the access network device and AMF304 communicate with each other through the NG-C interface. AMF304 and LMF305 communicate with each other through the NL1 interface, and AMF304 is equivalent to a router for communication between the access network device and LMF305. LMF305 is a network element, module or component in the new radio (NR) core network that provides positioning functions for terminal devices. LMF305 is used to calculate the location of the terminal device. The SMF306 can store the environment map and realize the reconstruction of the environment map. It realizes the interaction of environment, measurement and other information with the LMF305.

[0106] above Figure 3A In the communication system shown in FIG, LMF305 and SMF306 are two network elements deployed separately. In actual applications, LMF305 and SMF306 can also be deployed together or integrated together, that is, LMF305 and SMF306 are the same network element, which is not limited in this application. Figure 3B As shown, LMF305 and SMF306 are deployed or integrated together to form a network element, which provides sensing and positioning functions.

[0107] above Figure 3A and Figure 3B This example illustrates only two access network devices, namely, a gNB and an ng-eNB, in a communication system. In practice, the communication system may include at least one access network device, which is not specifically limited in this application.

[0108] In this application, the above Figure 3A and Figure 3B In the communication systems shown, LMF is the name of the current communication system. In future communication systems, the name of the LMF may change as the communication system evolves. For example, LMF may also be called a positioning device, a positioning center, a positioning server, a positioning management device, or a positioning management function device. Specifically, this application does not limit the name of LMF. In current or future communication systems, as long as a functional network element with other names similar to LMF has a function, it can be understood as LMF in the embodiments of this application and is applicable to the information sending method and information receiving method provided in the embodiments of this application.

[0109] In this application, the above Figure 3A and Figure 3B In the communication systems shown respectively, the name of the SMF may change with the evolution of the communication system. As long as the functional network element has other names with similar functions to the SMF, it can be understood as the SMF of this application and is applicable to the method provided in this application. For example, SMF can also be a communication perception function, a positioning management function, a perception management function entity, a perception function network element, a perception network element, a perception server, a positioning server, or other names. Specifically, this application does not limit the name of the SMF. The following embodiments mainly use the description method of SMF to introduce the execution operation of the functional network element.

[0110] The technical solution of the present application can be applied to cellular communication systems related to the 3rd Generation Partnership Project (3GPP). For example, a fourth generation (4G) communication system, a 5G communication system, and a communication system after the fifth generation communication system. For example, a sixth generation communication system. For example, a fourth generation communication system may include a long term evolution (LTE) communication system. A fifth generation communication system may include a new radio (NR) communication system. The technical solution of the present application can also be applied to a wireless fidelity (WiFi) system, a communication system that supports the integration of multiple wireless technologies, a device-to-device (D2D) system, or a vehicle to everything (V2X) communication system.

[0111] The following introduces the terminal equipment, access network equipment, perception management function, and positioning management function involved in this application.

[0112] Terminal equipment, also known as user equipment (UE), mobile station (MS), mobile terminal (MT), fixed wireless access (FWA), or customer premise equipment (CPE), is a device that includes wireless communication capabilities (providing voice / data connectivity to users). Examples include handheld devices with wireless connectivity, in-vehicle devices, and machine type communication (MTC) terminals. Currently, terminal devices include: mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self-driving (e.g., drones, vehicles), wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, and wireless terminals in smart homes. For example, wireless terminals in self-driving can be drones, helicopters, or airplanes. For example, wireless terminals in the Internet of Vehicles can be in-vehicle equipment, complete vehicle equipment, in-vehicle modules, vehicles, or ships. Wireless terminals in industrial control can be cameras, robots, or robotic arms. Wireless terminals in smart homes can be televisions, air conditioners, vacuum cleaners, speakers, or set-top boxes. The terminal device may also be a device or module that is connected to the communication system shown above and has corresponding communication functions. The terminal device is usually provided with a communication module, circuit or chip that performs the corresponding communication function, and the terminal device is also configured with program instructions for performing the corresponding communication function.

[0113] It should be noted that the terminal device can be a device or apparatus with a chip, or a device or apparatus with an integrated circuit, or a chip, chip system, module or control unit in the device or apparatus shown above, and this application does not limit it specifically. It should be noted that in this application, when referring to a terminal device, it can refer to the terminal device itself, or it can refer to a chip, functional module or integrated circuit in the terminal device that performs the method provided in this application, and this application does not limit it specifically.

[0114] Access network equipment (ANE) is a device deployed in a radio access network (RAN) to provide wireless communication capabilities for terminal devices. It connects terminal devices to the radio access network (RAN) nodes of a wireless network. It can also be called AN equipment, RAN entity, access node, network node, or communication device.

[0115] Specifically, the access network device may be an access network device for a cellular system related to the Third Generation Partnership Project (3GPP). For example, a 4G communication system or a 5G communication system. The access network device may also be an access network device in an open access network (openRAN, O-RAN, or ORAN) or a cloud radio access network (CRAN). Alternatively, the access network device may be an access network device in a communication system resulting from the fusion of two or more of the above communication systems.

[0116] Access network equipment includes but is not limited to: evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (for example, home evolved NodeB, or home Node B, HNB), base band unit (BBU), access point (AP) in wireless fidelity (WIFI) system, macro base station, micro base station, wireless relay node, donor node, wireless controller in CRAN scenario, wireless backhaul node, transmission point (TP) or transmission and reception point (TRP), etc., and can also be access network equipment in 5G mobile communication system. For example, the next generation NodeB (gNB), TRP, TP in the NR system; or one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G mobile communication system; or the access network device can also be a network node that constitutes a gNB or a transmission point. For example, a centralized unit (CU), a distributed unit (DU), a centralized unit-control plane (CU-CP), a centralized unit-user plane (CU-UP), or a radio unit (RU). The CU and DU can be set separately or included in the same network element, such as a BBU. The RU can be included in a radio frequency device or radio frequency unit. For example, in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). Alternatively, the access network device can also be a server, a wearable device, a vehicle, or an on-board device. For example, the access network device in V2X technology can be a roadside unit (RSU). It should be understood that the aforementioned TRP can be a device or module located on the network side of the aforementioned communication system and having corresponding communication functions. The TRP typically contains a communication module, circuit, or chip that performs the corresponding communication functions.The TRP also contains program instructions for corresponding communication functions.

[0117] It should be noted that in different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in an open radio access network (ORAN) system, CU may also be called an open centralized unit (O-CU) or an open CU, DU may also be called an open distributed unit (O-DU), CU-CP may also be called an open-centralized unit control plane (O-CU-CP), CU-UP may also be called an open-centralized unit user plane (O-CU-UP), and RU may also be called an open radio unit (O-RU). This application does not limit this. Any of the CU, CU-CP, CU-UP, DU and RU in this application may be implemented through a software module, a hardware module, or a combination of a software module and a hardware module.

[0118] Optionally, for network elements in the ORAN system, each network element may implement the protocol layer functions shown in Table 1 below.

[0119] Table 1

[0120]

[0121] It should be noted that, in the ORAN system, the access network device in this application may be one or more network elements in Table 1 above.

[0122] The following describes the architecture of the CU and DU of an access network device. The access network device includes at least one CU and at least one DU. Optionally, the access network device also includes at least one RU.

[0123] The following is an introduction using the example of an access network device including a CU and a DU. The CU has some functions of the core network, and the CU may include a CU-CP and a CU-UP. The CU and the DU may be configured according to the protocol layer functions of the wireless network they implement. For example, the CU is configured to implement the functions of the packet data convergence protocol (PDCP) layer and the protocol layers above it (for example, the RRC layer and / or the SDAP layer). The DU is configured to implement the functions of the protocol layers below the PDCP layer (for example, the RLC layer, the MAC layer, and / or the physical (PHY) layer). For another example, the CU is configured to implement the functions of the protocol layers above the PDCP layer (such as the RRC layer and / or the SDAP layer), and the DU is configured to implement the functions of the PDCP layer and the protocol layers below it (for example, the RLC layer, the MAC layer, and / or the PHY layer, etc.).

[0124] When a CU includes a CU-CP and a CU-UP, the CU-CP is used to implement the control plane functions of the CU, and the CU-UP is used to implement the user plane functions of the CU. For example, when the CU is configured to implement the functions of the PDCP layer, RRC layer, and SDAP layer, the CU-CP is used to implement the RRC layer functions and the control plane functions of the PDCP layer, and the CU-UP is used to implement the SDAP layer functions and the user plane functions of the PDCP layer.

[0125] The CU-CP can interact with network elements in the core network that implement control plane functions. These elements can be access and mobility elements, such as the AMF in 5G systems. The AMF is responsible for mobility management in mobile networks, such as location updates, network registration, and handovers.

[0126] The CU-UP can interact with network elements in the core network that implement user plane functions. Network elements in the core network that implement user plane functions, such as the user plane function (UPF) in the 5G system, are responsible for forwarding and receiving data in terminal devices.

[0127] The above configuration of CU and DU is only an example, and the functions of CU and DU can also be configured as needed. For example, the CU or DU can be configured to have the functions of more protocol layers, or the CU or DU can be configured to have partial processing functions of the protocol layer. For example, some functions of the RLC layer and the functions of the protocol layers above the RLC layer are set in the CU, and the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer are set in the DU. For another example, the functions of the CU or DU can be divided according to the service type or other system requirements. For example, according to the delay, the functions whose processing time needs to meet the smaller delay requirement are set in the DU, and the functions that do not need to meet the delay requirement are set in the CU.

[0128] The DU and RU can work together to implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of the DU and RU can be configured in various ways according to the design. For example, the DU is configured to implement the baseband function, and the RU is configured to implement the mid-RF function. For another example, the DU is configured to implement the high-layer functions in the PHY layer, and the RU is configured to implement the low-layer functions in the PHY layer or to implement the low-layer functions and the RF functions. The high-layer functions in the physical layer may include a part of the functions of the physical layer, which is closer to the MAC layer, and the low-layer functions in the physical layer may include another part of the functions of the physical layer, which is closer to the mid-RF side.

[0129] It should be noted that the access network device can be a device or apparatus with a chip, or a device or apparatus with an integrated circuit, or a chip, chip system, module or control unit in the aforementioned device or apparatus, and this application does not limit this. It should be noted that in this application, when referring to the access network device, it can refer to the access network device itself, or it can refer to the chip, functional module or integrated circuit in the access network device that completes the method provided in this application, and this application does not limit this.

[0130] The perception management function can select appropriate access network devices and / or terminal devices and send perception requests to the access network devices, thereby implementing the perception process between the access network devices and the terminal devices to achieve perception.

[0131] The positioning management function is used to provide positioning function to realize the positioning of terminal devices.

[0132] In order to facilitate understanding of the technical solution of this application, some technical terms involved in this application are introduced below.

[0133] 1. Beam: A beam is a communication resource. It can be wide, narrow, or any other type of beam. Beam formation can be achieved through beamforming or other techniques. Beamforming techniques include digital beamforming, analog beamforming, and hybrid digital / analog beamforming. Different beams can be considered different resources.

[0134] In the NR protocol, beam can be called spatial domain filter, spatial filter, spatial domain parameter, spatial parameter, spatial parameter, spatial domain setting, spatial setting, quasi-colocation (QCL) information, QCL assumption, or QCL indication, etc. The beam can be indicated by a TCI state parameter or by a spatial relation parameter. Therefore, in this application, beam can be replaced by spatial filter, spatial filter, spatial parameter, spatial parameter, spatial setting, spatial setting, QCL information, QCL assumption, QCL indication, TCI-state (including uplink TCI-state, downlink TCI-state), or spatial relationship, etc. The above terms are also equivalent to each other. Beam can also be replaced by other terms representing beams, which are not limited in this application.

[0135] A beam used to transmit a signal may be referred to as a transmission beam (Tx beam), a spatial domain transmission filter, a spatial transmission filter, a spatial transmission parameter, a spatial transmission parameter, a spatial domain transmission setting, or a spatial transmission setting. A downlink beam may be indicated by a TCI-state.

[0136] The beam used to receive a signal can be called a reception beam (Rx beam), a spatial domain reception filter, a spatial reception filter, a spatial domain reception parameter, a spatial reception parameter, a spatial domain reception setting, or a spatial reception setting. The uplink beam can be indicated by any of a spatial relationship, an uplink TCI-state, and a sounding reference signal (SRS) resource (indicating a transmit beam using the SRS). Therefore, the uplink beam can also be replaced by an SRS resource.

[0137] The transmit beam may refer to the distribution of signal strength in different directions in space after the signal is transmitted by the antenna, and the receive beam may refer to the distribution of signal strength in different directions in space of the wireless signal received from the antenna.

[0138] Furthermore, the beam may be a wide beam, a narrow beam, or other types of beams. The beam forming technology may be beamforming technology or other technologies. The beamforming technology may specifically be digital beamforming technology, analog beamforming technology, hybrid digital beamforming technology, or hybrid analog beamforming technology.

[0139] Beams generally correspond to resources. For example, when performing beam measurement, the network device measures different beams through different resources. The terminal device feeds back the measured resource quality, and the network device knows the quality of the corresponding beam. When data is transmitted, beam-related information can also be indicated by its corresponding resources. For example, the network device indicates the information of the physical downlink shared channel (PDSCH) beam of the terminal device through the TCI field in the downlink control information (DCI). Optionally, in the present application, the network device can be an access network device.

[0140] In one possible implementation, multiple beams with identical or similar communication characteristics are considered a single beam. A beam can include one or more antenna ports for transmitting data channels, control channels, and sounding signals. The one or more antenna ports that form a beam can also be considered an antenna port set.

[0141] 2. QCL: Quasi-colocation relationship is used to indicate that multiple resources have one or more identical or similar communication characteristics. For multiple resources with a quasi-colocation relationship, the same or similar communication configuration can be adopted. For example, if two antenna ports have a quasi-colocation relationship, the large-scale characteristics of the channel for transmitting a symbol on one port can be inferred from the large-scale characteristics of the channel for transmitting a symbol on the other port. Large-scale characteristics may include: delay spread, average delay, Doppler spread, Doppler shift, average gain, receiving parameters, terminal device receiving beam number, transmit / receive channel correlation, receive arrival angle, receiver antenna spatial correlation, main angle of arrival (AoA), average arrival angle, AoA spread, etc. Specifically, the colocation indication is used to indicate whether at least two groups of antenna ports have a colocation relationship, including: the colocation indication is used to indicate whether the channel state information reference signals sent by at least two groups of antenna ports come from the same transmission point, or the colocation indication is used to indicate whether the channel state information reference signals sent by at least two groups of antenna ports come from the same beam group.

[0142] 3. TCI: It can also be called TCI state (TCI-state). In uplink and downlink transmission, the correct beam needs to be used between the network device and the terminal device to achieve correct transmission. In downlink transmission, the network device needs to indicate to the terminal device the downlink beam it uses. The terminal device can determine the appropriate receiving beam based on the downlink beam, and the receiving beam is used to receive information from the network device. In uplink transmission, the network device also needs to indicate to the terminal device which uplink beam the terminal device uses to send information to the network device. The network device can determine the uplink beam with better signal quality for the terminal device. Both the uplink beam and the downlink beam can be indicated by the corresponding TCI state. Specifically, the downlink beam can be indicated by the downlink TCI state, and the uplink beam can be indicated by the uplink TCI state.

[0143] In the 3GPP protocol, the network device can indicate the TCI state to the terminal device through the TCI field in the DCI. The size of the TCI field is 3 bits, which can be specifically expressed as 8 different field values ​​(codepoints). Each field value of the TCI field can be associated with an index of a TCI state. The index of the TCI state can uniquely identify a TCI state, which can be a downlink TCI state or an uplink TCI state. Each field value of the TCI field can also be associated with two TCI state indexes, which can uniquely identify two TCI states, and the two TCI states can include a downlink TCI state and an uplink TCI state.

[0144] The downlink TCI state includes several parameters that allow the terminal device to determine the relevant information of the downlink transmit beam and thus determine the appropriate receive beam to receive information from the network device. The TCI state is configured by the network device for each terminal device. The structure of the downlink TCI state is as follows:

[0145]

[0146]

[0147] Each TCI state includes its own index (tci-StateId) and two quasi-colocation information (QCL-info). Each QCL-info includes a reference signal resource, which is used to indicate that the downlink transmission of the TCI state should use the same downlink timing, frequency offset or receiving beam as the reference signal resource. It is specifically determined by the type of the QCL-info. The QCL type can have four values ​​{typeA, typeB, typeC, typeD}. When the QCL type is typeA, typeB and typeC, the downlink transmission should be carried out using the same downlink timing and frequency offset as the reference signal resource. When the QCL type is typeD, the downlink transmission should be carried out using the same receiving beam as the reference signal resource. Of the two QCL-infos mentioned above, one is of typeD and the other is of typeA or typeB or typeC. The terminal device can determine which receiving beam to use to receive the corresponding downlink transmission through the QCL-info of typeD. The specific execution steps are as follows:

[0148] The network device indicates a downlink TCI state to the terminal device through DCI. The terminal device determines the reference signal resource in the QCL information of type D in the downlink TCI state. The terminal device uses the receiving beam of the reference signal resource as the receiving beam used for downlink transmission. It should be noted that the receiving beam of the reference signal resource is obtained by the terminal device in advance through the beam management process. Through the beam management process, the terminal device can determine which receiving beam is best to receive the reference signal resource, and use the receiving beam as the receiving beam of the reference signal resource.

[0149] The uplink TCI state includes a reference signal resource, which is used to indicate that the uplink transmission using this TCI state should use the same uplink transmit beam as the reference signal resource. The terminal device can determine which transmit beam to use for uplink transmission through this reference signal resource. In the uplink TCI state, the reference signal resource is not included in the QCL-info, and the QCL type is not distinguished, because there is no need to refer to the uplink timing and frequency offset information, only the uplink transmit beam. The structure of the uplink TCI state is shown below:

[0150]

[0151] The specific steps are as follows:

[0152] The network device indicates a certain uplink TCI state to the terminal device through the DCI. The terminal device determines the reference signal resource in the uplink TCI state. The terminal device uses the transmit beam of the reference signal resource as the transmit beam used by the terminal device for uplink transmission. It should be noted that the transmit beam of the reference signal resource is obtained by the terminal device in advance through the beam management process.

[0153] The following describes the configuration, activation and indication of TCI status.

[0154] TCI-state configuration: The network device configures multiple TCI-states to the terminal device through RRC signaling. These TCI-states all include a QCL-Info of type D. The network device can also configure TCI-states that do not include QCL-info of type D. However, these TCI-states are not used to indicate data transmission beams and are not further explained here.

[0155] TCI-state activation: After a network device is configured with multiple TCI-states, it must activate eight of them through a media access control element (MAC CE). These eight TCI-states correspond one-to-one to the eight values ​​of the TCI field in the DCI. That is, the MAC CE determines which TCI-states the eight values ​​of the DCI TCI field correspond to.

[0156] TCI state indication: The network device indicates a specific TCI-state through the TCI field in the DCI. For example, the value of the TCI field in the DCI sent by the network device to the terminal device is 000, indicating that the data transmission beam adopts the TCI state corresponding to 000. The reference signal contained in the QCL-Info of type D in this TCI state is the channel state information-reference signal (CSI-RS) with an index of #1, indicating that the beam used for data transmission is the same as the receiving beam corresponding to the CSI-RS with an index of #1. The receiving beam corresponding to the CSI-RS with an index of #1 can be determined through the beam measurement process and is known to the terminal device. Therefore, through the specific value of the TCI field, the terminal device can determine the beam corresponding to the data transmission beam, and thus adopt the corresponding beam to send or receive data.

[0157] It should be noted that the three descriptions of TCI state, TCI-state and TCI state in this article can be used interchangeably.

[0158] In this application, the perception reference signal can be a sounding reference signal (SRS), a phase tracking reference signal (PTRS), a demodulation reference signal (DMRS), a downlink positioning reference signal (DL-PRS), or other reference signals. As long as it is a reference signal sent by a terminal device for the access network device to perceive the environment, it can be considered as a perception reference signal involved in this application, and this application does not limit it. In this application, the perception reference signal resource is used for the terminal device to send the perception reference signal.

[0159] A possible configuration of the perception reference signal resource is described below, taking the perception reference signal resource as an SRS resource.

[0160]

[0161] The configuration of spatialRelationInfoPos-r16 is as follows:

[0162]

[0163] The SRS spatial correlation positioning information (SRS-SpatialRelationInfoPos) in the above-mentioned SRS resource includes the reference signal identifier associated with the SRS resource. As can be seen from the above configuration, the SRS resource is associated with the synchronization signal-broadcast channel measurement resource block (synchronization signal and physical boardcast channel block, SSB) index. The SSB index corresponds to a certain SSB, and the SSB configuration includes the spatial domain parameters for sending the SSB. The spatial domain parameters for sending the SSB can also be called a beam, that is, an association relationship can be established between the beam and the reference signal, and the beam can be used to send or receive the reference signal. Therefore, it can be understood that in this application, the perception reference signal resource corresponds to the beam, and one perception reference signal resource can correspond to one beam, which is used to send or receive the perception reference signal. Different perception reference signal resources correspond to different beams.

[0164] In the present application, optionally, the perception reference signal resource may also be an SRS resource, a CSI-RS resource, a DL-PRS resource, a DMRS resource, or a PTRS resource, which is not specifically limited in the present application.

[0165] In this application, the propagation path may also be referred to as a perception path or a multipath, which is not specifically limited in this application.

[0166] The following describes the technical solution of this application in conjunction with specific embodiments. In this application, the terminal device sends propagation path information to the access network device, specifically in conjunction with Figure 4 Alternatively, the terminal device sends the propagation path information to the perception management function, specifically in conjunction with Figure 7 The embodiment shown is described.

[0167] Figure 4 This is a schematic diagram of an embodiment of the information sending method and information receiving method of the present application. Figure 4 , the method includes the following steps.

[0168] It should be noted that Figure 4In the embodiment shown, the terminal device, access network device and perception management function are used as the execution subjects of the interaction diagram to illustrate the method, but the present application does not limit the execution subjects of the interaction diagram. Figure 4 In the embodiment shown, the execution subject in steps 401a, 401, 402, 403, 404, 405, and 406 is a terminal device.

The execution subject may also be a chip, chip system, or processor that supports the access network device to implement the method, or a logic module or software that can implement all or part of the access network device. Figure 4 The execution subject in step 406a and step 408 in the illustrated embodiment is the perception management function.

[0169] 401. The access network device sends a reference signal to the terminal device. Correspondingly, the terminal device receives the reference signal from the access network device.

[0170] Specifically, the terminal device can receive reference signals from the network device through multiple beams. Optionally, the network device can send reference signals in an omnidirectional manner. For example, the terminal device receives reference signals from the access network device through beams 1 to 4. Specifically, the terminal device can first receive the reference signal from the access network device through beam 1, then switch from beam 1 to beam 2, and receive the reference signal from the access network device through beam 2. Then, the terminal device switches from beam 2 to beam 3, and receives the reference signal from the access network device through beam 3. Then, the terminal device switches from beam 3 to beam 4, and receives the reference signal from the access network device through beam 4.

[0171] Optionally, the reference signal can be a channel state information reference signal (CSI-RS), a positioning reference signal (PRS), a synchronization signal / physical broadcasting channel (SSB), a demodulation reference signal (DMRS), a phase tracking reference signal (PTRS), or other reference signals, which are not limited in this application.

[0172] 402. The terminal device measures the reference signal to obtain propagation path information.

[0173] The propagation path information includes at least one of the following: the number of propagation paths between the terminal device and the access network device, the beam information corresponding to the propagation path, or the angle information corresponding to the propagation path.

[0174] For example, Figure 5 As shown, the terminal device receives the reference signal from the access network device through beam 1 to beam 4, and measures the reference signal to determine the number of propagation paths between the terminal device and the access network device, as shown in FIG. Figure 5 It can be seen that the number of propagation paths between the terminal device and the access network device is 4.

[0175] Optionally, the beam information includes the identifier, index, or associated reference signal information of at least one beam corresponding to each propagation path between the terminal device and the access network device. The at least one beam is the beam used by the terminal device to measure the reference signal to determine the propagation path. Optionally, one propagation path corresponds to one or more beams, or one beam corresponds to one or more propagation paths. The following is an example of one propagation path corresponding to one beam. For example, Figure 5 As shown, the terminal device receives a reference signal from the access network device via beam 1 and measures the reference signal to determine path 1, so path 1 corresponds to beam 1. The terminal device receives a reference signal from the access network device via beam 2 and measures the reference signal to determine path 2, so path 2 corresponds to beam 2. The terminal device receives a reference signal from the access network device via beam 3 and measures the reference signal to determine path 3, so path 3 corresponds to beam 3. The terminal device receives a reference signal from the access network device via beam 4 and measures the reference signal to determine path 4, so path 4 corresponds to beam 4. The beam information may include an identifier of beam 1 corresponding to path 1, an identifier of beam 2 corresponding to path 2, an identifier of beam 3 corresponding to path 3, and an identifier of beam 4 corresponding to path 4.

[0176] Optionally, the reference signal information associated with at least one beam includes at least one of the following: a reference signal type, index, identifier, or indication. For example, the reference signal type is SSB or CSI-RS. For details on the association between beams and reference signals, please refer to the previous description and will not be repeated here.

[0177] It should be noted that beam information can also be referred to as TCI state information. The TCI state information includes an identifier, index, or associated reference signal information of at least one TCI state corresponding to each propagation path between the terminal device and the access network device.

[0178] Optionally, the angle information includes at least one of the following: the arrival angle or departure angle of each propagation path of the reference signal between the terminal device and the access network device. Optionally, the arrival angle of each propagation path includes at least one of the following: the horizontal arrival angle of each propagation path, or the vertical arrival angle of each propagation path. The departure angle of each propagation path includes at least one of the following: the horizontal departure angle of each propagation path, or the vertical departure angle of each propagation path. For example, Figure 5 As shown, the angle information may include the horizontal arrival angle a1, vertical arrival angle b1, horizontal departure angle c1, and vertical departure angle d1 of path 1, the horizontal arrival angle a2, vertical arrival angle b2, horizontal departure angle c2, and vertical departure angle d2 of path 2, the horizontal arrival angle a3, vertical arrival angle b3, horizontal departure angle c3, and vertical departure angle d3 of path 3, and the horizontal arrival angle a4, vertical arrival angle b4, horizontal departure angle c4, and vertical departure angle d4 of path 4.

[0179] It should be noted that the above is introduced using the propagation path between the terminal device and the access network device as the NLOS path as an example. In fact, the propagation path between the terminal device and the access network device may also include the LOS path between the terminal device and the access network device, which is not specifically limited in this application.

[0180] Optionally, the terminal device measures the reference signal of the access network device to obtain propagation path information, including: the terminal device receives the reference signal from the access network device through multiple beams; the terminal device performs channel estimation based on the reference signal to obtain the channel power delay spectrum; the terminal device determines the propagation path information based on the channel power delay spectrum. Specifically, the terminal device uses the number of power peaks greater than a threshold value in the channel power delay spectrum as the number of propagation paths between the terminal device and the access network device. Alternatively, the terminal device uses the number of power peaks greater than or equal to a threshold value in the channel power delay profile (PDP) as the number of propagation paths between the terminal device and the access network device. For example, Figure 5As shown in FIG, the terminal device receives the reference signal from the access network device through beam 1 to beam 4. Then, the terminal device performs channel estimation based on the reference signal to obtain the channel PDP. Figure 6A As shown, the terminal device obtains the following information for the reference signal received through beam 1: Figure 6A As shown in curve 1, the reference signal received through beam 2 is obtained as follows Figure 6A As shown in curve 2, the reference signal received through beam 3 is obtained as follows Figure 6A As shown in curve 3, the reference signal received through beam 4 is obtained as follows Figure 6A As shown in curve 4. Figure 6B The diagram shows the synthesis of curves 1 to 4. Figure 6B It can be determined that there are four power peaks greater than the threshold value, namely points A, B, C, and D. Therefore, the terminal device can determine that there are four propagation paths between the terminal device and the access network device, namely paths 1 to 4. In other words, the terminal device can determine the presence of four sensing targets or sensing reflectors, which are considered to be four propagation paths, namely paths 1 to 4. Path 1 corresponds to beam 1, path 2 corresponds to beam 2, path 3 corresponds to beam 3, and path 4 corresponds to beam 4. The terminal device can determine the beam information of beams 1 to 4, as well as the angle information of paths 1 to 4 between the terminal device and the access network device.

[0181] It should be noted that the propagation path information can also be called multipath information, direction information, path information, or first information. Specifically, this application does not limit the name of the propagation path information.

[0182] Optionally, the beam information and angle information may also be sent separately, that is, not carried in the propagation path information.

[0183] Optionally, before step 402, the sensing management function interacts with the access network device to enable the sensing management function to determine whether the access network device has sensing capabilities. Optionally, the sensing management function may send a sensing information request to the access network device. The sensing information request is used to request the access network device to report sensing-related information. The access network device reports the sensing-related information and the location information of the access network device to the sensing management function. For example, the sensing-related information may include: an identifier of a sensing reference signal used for sensing, and / or information about the beam used to transmit the sensing reference signal.

[0184] 403. The terminal device sends the propagation path information to the access network device. Correspondingly, the access network device receives the propagation path information from the terminal device.

[0185] Optional, Figure 4The illustrated embodiment further includes step 401a. Step 401a may be performed before step 401.

[0186] 401a: The access network device sends a first request to the terminal device. Correspondingly, the terminal device receives the first request from the access network device.

[0187] The first request is used to request the terminal device to report the propagation path information between the terminal device and the access network device. Alternatively, the first request is used to request the terminal device to report the number of propagation paths between the terminal device and the access network device.

[0188] Optionally, the first request further includes threshold information, where the threshold information is used to determine the number of propagation paths between the terminal device and the access network device.

[0189] In one possible implementation, the threshold information includes at least one threshold value. For example, the threshold information includes a threshold value. The terminal device receives a reference signal from the access network device via multiple beams and performs channel estimation based on the reference signal to obtain a channel power delay profile (PDP). The terminal device then determines the number of power peaks exceeding the threshold value based on the channel PDP to determine the number of propagation paths between the terminal device and the access network device.

[0190] Optionally, the threshold information also includes the perceived target type corresponding to each threshold value in the at least one threshold value. Optionally, the perceived target type includes a drone, a building, a bridge, or a car. In other words, different perceived target types correspond to different threshold values, which facilitates accurate perception of the environment.

[0191] Optionally, at least one threshold value can be determined based on at least one of the communication link between the terminal device and the access network device, the transmission power, frequency, wavelength, path loss of the reference signal sent by the access network device, or the distance between the terminal device and the access network device.

[0192] It should be noted that the access network device can also send the threshold information to the terminal device through other messages, which is not limited in this application.

[0193] In step 401a, the first request including the threshold information is only one possible implementation method. Optionally, the threshold information may be pre-configured in the terminal device, or determined by the terminal device itself, which is not specifically limited in this application.

[0194] Optionally, the first request is a sensing measurement request, or a sensing request, or a measurement request, which is not specifically limited in this application. Accordingly, the propagation path information in the above step 403 can be carried in a sensing measurement response, a sensing response, or a measurement response.

[0195] Optional, Figure 4 The illustrated embodiment further includes step 404 and step 405. Step 404 and step 405 may be performed after step 403.

[0196] 404. The access network device determines sensing reference signal resource configuration information according to the propagation path information.

[0197] The perception reference signal resource configuration information is used to configure at least one perception reference signal resource.

[0198] In one possible implementation, at least one perception reference signal resource is a path-level perception reference signal resource. Specifically, a path-level perception reference signal resource can be represented as follows: the reference signal associated with the spatial information contained in the perception reference signal resource configuration information is a path-level reference signal, which can be understood as being associated with a path corresponding to the reference signal, which can be the strongest path, the first path, or the second strongest path. The terminal device transmits the reference signal through the perception reference signal resource. Accordingly, the access network device receives the reference signal from the terminal device and measures the reference signal to determine a corresponding propagation path, thereby determining associated spatial information, such as beam, angle information, etc. For example, the perception reference signal resource is an SRS resource, which is a path-level perception reference signal resource. As can be seen from the configuration of the SRS resource described above, the SRS spatial related information (SRS-SpatialRelationInfoPos) includes a reference signal identifier associated with the SRS resource. The reference signal corresponding to the reference signal identifier is a path-level reference signal.

[0199] In another possible implementation, at least one perception reference signal resource is a beam-level perception reference signal resource. Specifically, the beam-level perception reference signal resource can be expressed as follows: the reference signal associated with the spatial information contained in the perception reference signal resource configuration information is a beam-level reference signal, which can be understood as a certain reference signal, rather than a certain path corresponding to this reference signal. The terminal device sends the reference signal on the perception reference signal resource through the beam associated with the perception reference signal resource. Correspondingly, the access network device receives the reference signal from the terminal device and measures the reference signal to determine one or more propagation paths. For example, the perception reference signal resource is an SRS resource, and the SRS resource is a beam-level perception reference signal resource. As can be seen from the configuration of the aforementioned SRS resource, the SRS space-related information includes a reference signal identifier associated with the SRS resource. The reference signal corresponding to the reference signal identifier is a beam-level reference signal.

[0200] 405. The access network device sends the sensing reference signal resource configuration information to the terminal device. Correspondingly, the terminal device receives the sensing reference signal resource configuration information from the access network device.

[0201] Optionally, the above step 405 may also be replaced and described as: the access network device configures at least one perception reference signal resource for the terminal device.

[0202] It should be noted that the access network device may also send the perception reference signal resource configuration information to the core network device. Correspondingly, the core network device receives the perception reference signal resource configuration information from the access network device.

[0203] Optionally, the perception reference signal resource configuration information is carried in a radio resource control (RRC) message.

[0204] Optional, Figure 4 The illustrated embodiment further includes steps 406 to 408. Steps 406 to 408 may be performed after step 405.

[0205] 406. The terminal device sends a perception reference signal to the access network device through at least one perception reference signal resource. Correspondingly, the access network device receives the perception reference signal from the terminal device.

[0206] In a possible implementation, the at least one perception reference signal resource is a path-level perception reference signal resource. Figure 5 As shown, each path from path 1 to path 4 corresponds to a perception reference signal resource. The terminal device sends a perception reference signal to the access network device through the perception reference signal resource corresponding to each path. Correspondingly, the access network device receives the perception reference signal from the terminal device.

[0207] Therefore, the access network equipment can configure appropriate sensing reference signal resources for the terminal equipment based on the propagation path information, thereby improving the accuracy of the access network equipment in measuring the sensing reference signal and thus improving the accuracy of the environment perception.

[0208] Optional, Figure 4 The illustrated embodiment further includes step 406a. Step 406a may be performed before step 406.

[0209] 406a. The perception management function sends a second request to the access network device. Correspondingly, the access network device receives the second request from the perception management function.

[0210] The second request is used to request the access network device to perceive the environment.

[0211] Optionally, the second request is a perception measurement request, or a perception request, or a measurement request, which is not specifically limited in this application.

[0212] 407. The access network device measures the perception reference signal to obtain a perception measurement result.

[0213] In one possible implementation, the perception reference signal is carried on at least one perception reference signal resource. The at least one perception reference signal resource is a path-level perception reference signal resource. The perception measurement results may include delay, energy, arrival angle (e.g., horizontal arrival angle and / or vertical arrival angle), and / or phase of multiple propagation paths obtained by the access network device measuring the perception reference signal.

[0214] In another possible implementation, the perception reference signal is carried on at least one perception reference signal resource. The at least one perception reference signal resource is a beam-level perception reference signal resource. The perception measurement result may include the delay, energy, arrival angle (e.g., horizontal arrival angle and / or vertical arrival angle), and / or phase corresponding to the first path or the target path, respectively, obtained by the access network device measuring the perception reference signal.

[0215] 408. The access network device sends the perception measurement result to the perception management function. Correspondingly, the perception management function receives the perception measurement result from the access network device.

[0216] Optionally, the perception measurement result is carried in a perception measurement response, or a perception response, or a measurement response, which is not specifically limited in this application.

[0217] In this embodiment of the present application, a terminal device measures a reference signal from an access network device to obtain propagation path information. This propagation path information includes at least one of the following: the number of propagation paths between the terminal device and the access network device, corresponding beam information, or corresponding angle information. The terminal device then transmits the propagation path information to the access network device. This enables the access network device to obtain propagation path information between the terminal device and the access network device, facilitating accurate environmental perception for the access network device, improving resolution for different perceived targets, and enhancing perception accuracy.
