[0024] In a possible implementation of the first aspect, the second aspect, or the third aspect, the at least one beam is a beam used by the terminal device to measure the reference signal to determine the propagation path. The at least one beam can also be referred to as at least one receiving beam. The terminal device receives the reference signal through the at least one receiving beam to determine the propagation path.

[0095] The embodiments of the application provide a method for transmitting information, a method for receiving information and related apparatuses, so that an access network device or a sensing management function obtains propagation path information between a terminal device and the access network device, which is beneficial to precise sensing of an environment by the access network device or the sensing management function, and improves sensing precision.

[0096] In this application, the reference to "one embodiment" or "some embodiments" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the application. The appearances of the phrases "in one embodiment", "in some embodiments", "in other embodiments", "in additional embodiments" and so on in various places in the specification are not necessarily all referring to the same embodiment, but can refer to one or more but not all embodiments, unless otherwise specified. The terms "including", "containing", "having" and their variants mean "including but not limited to", unless otherwise specified.

[0097] In the description of the present application, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" herein is only a description of the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can mean: A exists alone, A and B exist together, and B exists alone. In addition, "at least one" means one or more, and "multiple" means two or more. "At least one of the following" or the like means any combination of the items, including any combination of single or multiple 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. Where a, b, c can be single or multiple.

[0098] With the rapid development of wireless communication technology, base stations as the core components of the network, their functions and application scenarios are also expanding. In recent years, the technology of using base stations for environmental perception has gradually attracted attention. This technology is based on the interaction between the base station and the surrounding environment, by collecting and analyzing the signals received by the base station, to achieve the perception and monitoring of the surrounding environment.

[0099] In the field of environmental perception, traditional methods usually rely on specialized sensors and devices, such as cameras, radars, or infrared detectors, etc. However, these methods have some problems, such as high cost, difficult deployment, affected by weather conditions, etc. In contrast, using base stations for environmental perception has many advantages.

[0100] Base stations have a wide range of coverage. As the infrastructure of wireless communication networks, base stations usually cover the entire city or a specific area. This means that using base stations for environmental perception can achieve real-time monitoring of large areas, providing valuable data support for urban planning, traffic management, disaster warning, etc. Secondly, base stations have the characteristics of continuous online. Base stations need to provide communication services for users 24 hours a day, so they are always in working condition. This makes it possible to use base stations for environmental perception to achieve real-time, continuous data collection and analysis, and timely discovery and processing of environmental problems. In addition, using base stations for environmental perception can also reduce costs. Since base stations have been widely deployed in cities, there is no need to install a large number of additional sensors and devices. Only by upgrading and modifying the existing base stations, the perception and monitoring of the surrounding environment can be achieved. This not only saves a lot of investment costs, but also avoids repeated construction and resource waste.

[0101] There is a problem of limited coverage range when sensing by a base station. The base station can only effectively sense and detect strong reflection targets in a visible area. As shown in FIG. 1, for the base station, the sensing area is divided into a line-of-sight (LOS) area and a non-line-of-sight (NLOS) area. Due to the obstruction of obstacles, the target in the NLOS area cannot be effectively sensed. For the NLOS area, a terminal device can be introduced to assist the base station in sensing. For example, as shown in FIG. 2, the terminal device assists the base station to implement sensing of the environment. Specifically, the base station sends a sensing reference signal, which is reflected by a reflector and then reflected by a cylinder to the terminal device. The terminal device can measure the sensing reference signal to obtain a sensing measurement result. The reflector and the cylinder can be regarded as sensing targets. If there are multiple sensing targets to be detected, different beams need to be used to send the sensing reference signal, so as to improve the detection accuracy of the sensing targets.

[0102] When the base station is used for environment sensing, if there are multiple sensing targets in the environment, or if there are multiple propagation paths in the environment, how to determine the propagation path between the terminal device and the base station in the environment is a problem worth considering. Further, the terminal device needs to send a sensing reference signal through multiple beams, and therefore how to configure the sensing reference signal resource for the terminal device is also a problem worth considering.

[0103] The present application provides corresponding technical solutions to enable an access network device or a sensing management function to obtain the propagation path information between the terminal device and the access network device, which is conducive to the accurate sensing of the environment by the access network device or the sensing management function and improves the sensing accuracy. For details, please refer to the embodiments described below.

[0104] The following describes a communication system to which the present application is applicable. The present application is still applicable to other communication systems, and the present application is not limited in this regard.

[0105] FIG. 3A is a schematic diagram of a communication system according to an embodiment of the present application. As shown in FIG. 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.

[0106] The terminal device 301 communicates with an access network device (such as the gNB 302 or the ng-eNB 303 in FIG. 3A) through a Uu interface. The ng-eNB 303 is an access network device in a long term evolution (LTE) communication system, and the gNB 302 is an access network device in a new radio (NR) communication system. In the communication system, the access network devices communicate with each other through an Xn interface, and the access network devices and the AMF 304 communicate through an NG-C interface. The AMF 304 and the LMF 305 communicate through an NL1 interface, and the AMF 304 serves as a router for communication between the access network device and the LMF 305. The LMF 305 is a network element, module or component in a new radio (NR) core network that provides positioning functions for a terminal device, and the LMF 305 is used for positioning calculation of the location of the terminal device. The SMF 306 can store an environmental map and can implement reconstruction of the environmental map, and the SMF 306 interacts with the LMF 305 to exchange environmental and measurement information.

[0107] In the communication system shown in FIG. 3A, the LMF 305 and the SMF 306 are two network elements deployed separately, and in actual applications, the LMF 305 and the SMF 306 can also be deployed or integrated together, that is, the LMF 305 and the SMF 306 are the same network element, and the specific application is not limited. For example, as shown in FIG. 3B, the LMF 305 and the SMF 306 are deployed or integrated together to become a network element that provides sensing functions and positioning functions.

[0108] FIGS. 3A and 3B only show an example in which the communication system includes two access network devices of gNB and ng-eNB. In actual applications, the communication system can include at least one access network device, and the specific application is not limited.

[0109] In the communication systems shown in FIGS. 3A and 3B, the LMF is the name of the current communication system, and in the future communication system, the name of the LMF can change with the evolution of the communication system. For example, the LMF can also be referred to as a positioning device, a positioning center, a positioning server, a positioning management device, or a positioning management function device, and the specific application does not limit the name of the LMF. In the current communication system or the future communication system, as long as other functional network elements with similar functions to the LMF have other names, the LMF in the embodiments of the present application can be understood, and the information sending method and the information receiving method provided by the embodiments of the present application are applicable.

[0110] In the present application, the name of the SMF in the communication system shown in FIG. 3A and FIG. 3B respectively may change as the communication system evolves. As long as other functional network elements with similar functions to the SMF have other names, they can be understood as the SMF of the present application and are applicable to the methods provided by the present application. For example, the SMF can also be a communication awareness function, a positioning management function, an awareness management function entity, an awareness function network element, an awareness network element, an awareness server, a positioning server, or other names, and the name of the SMF is not limited in the present application. The following embodiments mainly use the description of the SMF to introduce the execution operation of the functional network element.

[0111] The technical solutions of the present application can be applied to a third generation partnership project (3rd generation partnership project, 3GPP) related cellular communication system. For example, a fourth generation (4th generation, 4G) communication system, a 5G communication system, a communication system after the fifth generation communication system. For example, a sixth generation communication system. For example, the fourth generation communication system can include an LTE communication system. The fifth generation communication system can include an NR communication system. The technical solutions of the present application can also be applied to a wireless fidelity (wireless fidelity, WiFi) system, a communication system supporting multiple wireless technology fusion, a device-to-device (device-to-device, D2D) system, or a vehicle-to-everything (vehicle to everything, V2X) communication system.

[0112] The terminal device, access network device, awareness management function, and positioning management function related to the present application are introduced below.

[0113] Terminal device, also known as user equipment (UE), mobile station (MS), mobile terminal (MT), fixed wireless access (FWA), customer premise equipment (CPE), etc. The terminal device is a device including a wireless communication function (providing voice / data connectivity to users). For example, handheld devices with wireless connection functions, vehicle-mounted devices, machine type communication (MTC) terminals, etc. At present, the terminal device can include: mobile phone, tablet computer, notebook computer, palm computer, mobile internet device (MID), wearable device, virtual reality (VR) device, augmented reality (AR) device, wireless terminal in industrial control, wireless terminal in self driving (e.g. drone, vehicle), wireless terminal in remote medical surgery, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, or wireless terminal in smart home, etc. For example, the wireless terminal in self driving can be a drone, helicopter, or airplane, etc. For example, the wireless terminal in Internet of Vehicles can be a vehicle-mounted device, whole vehicle device, vehicle-mounted module, vehicle, or ship, etc. The wireless terminal in industrial control can be a camera, robot, or mechanical arm, etc. The wireless terminal in smart home can be a television, air conditioner, sweeping machine, sound box, or set-top box, etc. The terminal device can also be a device or module with corresponding communication function accessing the above-mentioned communication system. The terminal device is usually provided with a communication module, circuit or chip for executing corresponding communication functions, and is also configured with program instructions for executing corresponding communication functions.

[0114] It should be noted that the terminal device can be a device or apparatus with a chip, or a device or apparatus integrated with a circuit, or a chip, chip system, module or control unit in the above-mentioned devices or apparatus, which is not limited in the present application. It should be noted that in the present application, when referring to the terminal device, it can refer to the terminal device itself, or the chip, functional module or integrated circuit in the terminal device for completing the method provided in the present application, which is not limited in the present application.

[0115] The access network device is a kind of device deployed in wireless access network to provide wireless communication function for terminal device. The access network device can access terminal device to the radio access network (RAN) node of wireless network, which can also be called access network device, RAN entity, access node, network node, or communication device, etc.

[0116] Specifically, the access network device can be the access network device of the 3rd generation partnership project (3GPP) related cellular system. For example, 4G communication system, or 5G communication system. The access network device can also be the access network device in openRAN (O-RAN or ORAN) or cloud radio access network (CRAN). Or, the access network device can also be the access network device in the communication system obtained by fusing two or more than two of the above communication systems.

[0117] The access network device includes, but is not limited to, an evolved Node B (eNB), a radio network controller (RNC), a Node B (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (for example, a home evolved NodeB, or home Node B, HNB), a baseband unit (BBU), an access point (AP) in a wireless fidelity (WiFi) system, a macro base station, a micro base station, a wireless relay node, a donor node, a wireless controller in a CRAN scenario, a wireless backhaul node, a transmission point (TP), or a transmission and reception point (TRP), and the like, and can also be an access network device in a 5G mobile communication system. For example, a next generation NodeB (gNB), a TRP, or a TP in an NR system; or one or a group (including multiple antenna panels) of antenna panels of a base station in a 5G mobile communication system; or the access network device can also be a network node constituting 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), and the like. The CU and the DU can be separately arranged, or can be included in the same network element, for example, a BBU. The RU can be included in a radio frequency device or a radio frequency unit. For example, in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). Or the access network device can also be a server, a wearable device, a vehicle or a vehicle-mounted device, and the like. For example, the access network device in V2X technology can be a road side unit (RSU). It should be understood that the above-mentioned TRP can be a device or module located at the network side of the above-mentioned communication system and having corresponding communication functions. The TRP is usually provided with a communication module, circuit, or chip for performing corresponding communication functions.The TRPs also have program instructions configured for respective communication functions.

[0118] It should be noted that in different systems, the CU (or CU-CP and CU-UP), DU or RU can also have different names, but those skilled in the art can understand their meanings. For example, in an open radio access network (ORAN) system, the CU can also be referred to as an open centralized unit (O-CU) or an open CU, the DU can also be referred to as an open distributed unit (O-DU), the CU-CP can also be referred to as an open centralized unit control plane (O-CU-CP), the CU-UP can also be referred to as an open centralized unit user plane (O-CU-UP), and the RU can also be referred to as an open radio unit (O-RU). The specific application is not limited. Any one of the CU, CU-CP, CU-UP, DU and RU in the present application can be realized by a software module, a hardware module, or a combination of a software module and a hardware module.

[0119] Optionally, for network elements in the ORAN system, each network element can implement the protocol layer functions shown in Table 1 below.

[0120] Table 1

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

[0122] The architecture of the CU and the DU of the access network device will be introduced below. 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 introduced by taking an access network device including a CU and a DU as an example. The CU has part of the function of the core network, and the CU can include a CU-CP and a CU-UP. The CU and the DU can be configured according to the protocol layer function of the wireless network they implement. For example, the CU is configured to implement the function of the packet data convergence protocol (PDCP) layer and the protocol layer above (for example, the function of the RRC layer and / or the SDAP layer). The DU is configured to implement the function of the protocol layer below the PDCP layer (for example, the function of the RLC layer, the MAC layer, and / or the physical (PHY) layer). For another example, the CU is configured to implement the function of the protocol layer above the PDCP layer (for example, the function of the RRC layer and / or the SDAP layer), and the DU is configured to implement the function of the protocol layer below the PDCP layer (for example, the function of the RLC layer, the MAC layer, and / or the PHY layer, etc.).

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

[0125] The CU-CP can interact with a network element in the core network for implementing the control plane function. The network element in the core network for implementing the control plane function can be an access and mobility function network element, for example, an AMF in a 5G system. The AMF is used to be responsible for the mobility management in the mobile network, such as the location update of the terminal device, the registration network of the terminal device, the handover of the terminal device, etc.

[0126] The CU-UP can interact with a network element in the core network for implementing the user plane function. The network element in the core network for implementing the user plane function, for example, a user function (UPF) in a 5G system, is used to be responsible for the forwarding and receiving of data in the terminal device.

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

[0128] The DU and the RU can cooperate to jointly implement the functions of the PHY layer. One DU can be connected to one or more RUs. The functions of the DU and the RU can be configured in multiple ways according to design. For example, the DU is configured to implement baseband functions, and the RU is configured to implement intermediate radio frequency functions. For another example, the DU is configured to implement high-layer functions in the PHY layer, and the RU is configured to implement low-layer functions in the PHY layer or implement the low-layer functions and radio frequency functions. The high-layer functions in the PHY layer can include a part of functions of the PHY layer that are closer to the MAC layer, and the low-layer functions in the PHY layer can include another part of functions of the PHY layer that are closer to the intermediate radio frequency 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 integrated with a circuit, or a chip, a chip system, a module, or a control unit in the foregoing devices or apparatus, and the specific application is not limited. It should be noted that in the present application, when referring to the access network device, it can refer to the access network device itself, or refer to a chip, a functional module, or an integrated circuit in the access network device that completes the method provided in the present application, and the specific application is not limited.

[0130] The awareness management function can select a suitable access network device and / or terminal device, and send an awareness request to the access network device. The awareness process between the access network device and the terminal device is implemented, so as to realize awareness.

[0131] The positioning management function is configured to provide a positioning function, and to implement positioning of the terminal device.

[0132] In order to facilitate understanding of the technical solutions of the present application, some technical terms related to the present application are introduced below.

[0133] 1、beam: A beam is a kind of communication resource. A beam can be a wide beam, or a narrow beam, or other types of beams, and the technology for forming a beam can be beamforming technology or other technology. Beamforming technology can be digital beamforming technology, analog beamforming technology, and hybrid digital / analog beamforming technology. Different beams can be considered as different resources.

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

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

[0136] A beam for receiving a signal can be referred to as 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. An uplink beam can be indicated by any one of a spatial relationship, an uplink TCI-state, a sounding reference signal (SRS) resource (indicating a transmission beam using the SRS). Therefore, the uplink beam can also be replaced by the SRS resource.

[0137] A transmission beam can refer to a distribution of signal strength in different directions in space after a signal is transmitted by an antenna, and a reception beam can refer to a distribution of signal strength in different directions in space of a wireless signal received by an antenna.

[0138] In addition, a beam can be a wide beam, or a narrow beam, or other types of beams. The technology for forming a beam can be a beamforming technology or other technologies. The beamforming technology can be a digital beamforming technology, an analog beamforming technology, a hybrid digital beamforming technology, or a hybrid analog beamforming technology, etc.

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

[0140] In one possible implementation, multiple beams with the same or similar communication characteristics are considered as one beam. One beam can include one or more antenna ports for transmitting data channels, control channels, sounding signals, and the like. One or more antenna ports forming one beam can also be regarded as one antenna port set.

[0141] 2、QCL: Quasi Co-Location is used to indicate that multiple resources have one or more same or similar communication characteristics. For multiple resources with quasi co-location, the same or similar communication configuration can be used. For example, if two antenna ports have quasi co-location, the channel large-scale characteristics of one port transmitting one symbol can be inferred from the channel large-scale characteristics of another port transmitting one symbol. The large-scale characteristics can include delay spread, average delay, Doppler spread, Doppler shift, average gain, reception parameters, terminal device reception beam number, transmission / reception channel correlation, reception angle of arrival, spatial correlation of receiver antennas, main angel-of-arrival (AoA), average angle of arrival, spread of AoA, and the like. Specifically, the co-location indication is used to indicate whether at least two groups of antenna ports have co-location relationship, including: the co-location 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 co-location 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: Also referred to as TCI-state. In uplink and downlink transmission, both the network device and the terminal device need to use the correct beam to achieve correct transmission. In downlink transmission, the network device needs to indicate the downlink beam it uses to the terminal device. The terminal device can determine a suitable reception beam according to the downlink beam, which 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 of 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 represented 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, which can include a downlink TCI state and an uplink TCI state.

[0144] The downlink TCI state includes several parameters, and the terminal device can determine the related information of the downlink transmission beam through these parameters, so as to determine to use the appropriate receiving beam to receive the information from the network device. The TCI state is configured by the network device to each terminal device, and the structure of the downlink TCI state is as follows:

[0145] 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. The specific type of the QCL-info determines it. The QCL type can have four values {typeA, typeB, typeC, typeD}. When the QCL type is typeA, typeB and typeC, the same downlink timing and frequency offset as the reference signal resource should be used for downlink transmission. When the QCL type is typeD, the same receiving beam as the reference signal resource should be used for downlink transmission. Among the above two QCL-info, one is typeD and the other is typeA or typeB or typeC. The terminal device can determine which receiving beam to use to receive the corresponding downlink transmission through the typeD QCL-info. The specific execution steps are as follows:

[0146] The network device indicates a certain downlink TCI state to the terminal device through DCI. The terminal device determines the reference signal resource in the typeD QCL information of the downlink TCI state. The terminal device takes the receiving beam of the reference signal resource as the receiving beam 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 the best to receive the reference signal resource, and take the receiving beam as the receiving beam of the reference signal resource.

[0147] The uplink TCI state includes a reference signal resource, which is used to indicate that the uplink transmission using the TCI state should use the same uplink sending beam as the reference signal resource. The terminal device can determine which sending beam to use for uplink transmission through the reference signal resource. In the uplink TCI state, the reference signal resource is not included in the QCL-info, nor is it distinguished by the QCL type, because it is not necessary to refer to the uplink timing and frequency offset information, but only to the uplink sending beam. The structure of the uplink TCI state is as follows:

[0148] The specific execution steps are as follows:

[0149] The network device indicates a certain uplink TCI state to the terminal device through DCI. The terminal device determines the reference signal resource in the uplink TCI state. The terminal device takes the sending beam of the reference signal resource as the sending beam for uplink transmission of the terminal device. It should be noted that the sending beam of the reference signal resource is obtained by the terminal device in advance through the beam management process.

[0150] The configuration, activation and indication of the TCI state are introduced below.

[0151] TCI-state configuration: The network device configures multiple TCI-states to the terminal device through RRC signaling. These TCI-states all include a typeD QCL-Info. The network device can also configure TCI-states that do not include typeD QCL-info, but these TCI-states are not used for data transmission beam indication, so they are not further described here.

[0152] TCI-state activation: after the network device configures multiple TCI-states, it also needs to activate 8 of them through a media or medium access control control element (MAC CE). The 8 TCI-states are one-to-one corresponding to the 8 values of the TCI field in the DCI. That is, which 8 TCI-states correspond to the 8 values of the TCI field in the DCI is determined by the MAC CE. The media access control control element can also be referred to as the medium access control control element.

[0153] 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 typeD QCL-Info in the TCI state is the channel state information-reference signal (CSI-RS) with index #1, indicating that the data transmission beam is the same as the receiving beam corresponding to the CSI-RS with index #1. The receiving beam corresponding to the CSI-RS with index #1 can be determined through a 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 transmit or receive data using the corresponding beam.

[0154] It should be noted that the three descriptions of TCI state, TCI-state and TCI state in this paper can be replaced with each other.

[0155] In this application, the perception reference signal can be SRS, phase tracking reference signal (PTRS), demodulation reference signal (DMRS), downlink positioning reference signal (DL-PRS), or other reference signals, as long as it is a reference signal sent by the terminal device for the network device to perceive the environment. It can be considered as the perception reference signal involved in this application, and the specific application is not limited. In this application, the perception reference signal resource is used for the terminal device to send the perception reference signal.

[0156] The following introduces a possible configuration of the sensing reference signal resource taking the sensing reference signal resource as the SRS resource.

[0157] The configuration in spatialRelationInfoPos-r16 is as follows:

[0158] The SRS spatial correlation positioning information (SRS-SpatialRelationInfoPos) in the SRS resource includes the reference signal identifier associated with the SRS resource, as shown in the above configuration, the SRS resource is associated with a synchronization signal and physical broadcast channel block (SS / PBCH block, SSB for short) index. The SSB index corresponds to a certain SSB, and the configuration of the SSB includes a spatial parameter for transmitting the SSB, which can also be referred to as a beam. That is, an association relationship can be established between the beam and the reference signal, and the beam can be used to transmit or receive the reference signal. Therefore, it can be understood that in the present application, the sensing reference signal resource corresponds to a beam, and one sensing reference signal resource can correspond to one beam, which is used to transmit or receive the sensing reference signal. Different sensing reference signal resources correspond to different beams.

[0159] In the present application, the sensing reference signal resource can also be an SRS resource, a CSI-RS resource, a DL-PRS resource, a DMRS resource, or a PTRS resource, which is not limited in the present application.

[0160] In the present application, the propagation path can also be referred to as a sensing path or a multipath, which is not limited in the present application.

[0161] The technical solutions of the present application will be introduced in combination with specific embodiments. In the present application, the terminal device sends the propagation path information to the access network device, which will be introduced in combination with the embodiment shown in FIG. 4. Alternatively, the terminal device sends the propagation path information to the sensing management function, which will be introduced in combination with the embodiment shown in FIG. 7.

[0162] FIG. 4 is a schematic diagram of one embodiment of the information sending method and the information receiving method of the present application. Please refer to FIG. 4, the method includes the following steps.

[0163] It should be noted that the terminal device, the access network device and the perception management function in the embodiment shown in FIG. 4 are taken as examples to illustrate the execution subject of the interaction, but the application is not limited to the execution subject of the interaction. For example, the execution subject in steps 401a, 401, 402, 403, 404, 405 and 406 in the embodiment shown in FIG. 4 is the terminal device, and the execution subject can also be a chip, a chip system or a processor supporting the terminal device to implement the method, and can also be a logic module or software capable of implementing all or part of the function of the terminal device. The execution subject in steps 401a, 401, 403, 404, 405, 406a, 406, 407 and 408 in the embodiment shown in FIG. 4 is the access network device, and the execution subject can also be a chip, a chip system or a processor supporting the access network device to implement the method, and can also be a logic module or software capable of implementing all or part of the function of the access network device. The execution subject in steps 406a and 408 in the embodiment shown in FIG. 4 is the perception management function, and the execution subject can also be a chip, a chip system or a processor supporting the perception management function to implement the method, and can also be a logic module or software capable of implementing all or part of the function of the perception management function.

[0164] 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.

[0165] Specifically, the terminal device can receive the reference signal from the network device through multiple beams. Optionally, the network device can send the reference signal in all directions. For example, the terminal device receives the reference signal 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, receives the reference signal from the access network device through beam 3, and then switches from beam 3 to beam 4, and receives the reference signal from the access network device through beam 4.

[0166] Optionally, the reference signal can be a channel state information reference signal (CSI-RS), a positioning reference signal (PRS), an SSB, a DMRS, a PTRS or other reference signals, which are not limited in the application.

[0167] 402. The terminal device measures the reference signal to obtain the propagation path information.

[0168] The propagation path information includes at least one of the following: a number of propagation paths between the terminal device and the access network device, beam information corresponding to the propagation paths, or angle information corresponding to the propagation paths.

[0169] For example, as shown in FIG. 5, the terminal device receives reference signals from the access network device through beams 1 to 4, and measures the reference signals to determine the number of propagation paths between the terminal device and the access network device. As can be seen from FIG. 5, the number of propagation paths between the terminal device and the access network device is 4.

[0170] Optionally, the beam information includes at least one of the following: an identifier, an 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 a 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. Hereinafter, an example in which one propagation path corresponds to one beam is introduced. For example, as shown in FIG. 5, the terminal device receives reference signals from the access network device through beam 1, and measures the reference signals to determine path 1, so path 1 corresponds to beam 1. The terminal device receives reference signals from the access network device through beam 2, and measures the reference signals to determine path 2, so path 2 corresponds to beam 2. The terminal device receives reference signals from the access network device through beam 3, and measures the reference signals to determine path 3, so path 3 corresponds to beam 3. The terminal device receives reference signals from the access network device through beam 4, and measures the reference signals to determine path 4, so path 4 corresponds to beam 4. The beam information can 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.

[0171] Optionally, the reference signal information associated with the at least one beam includes at least one of the following: a type, an index, an identifier, or an indication of the reference signal. For example, the type of the reference signal is SSB or CSI-RS. The association between the beam and the reference signal can be referred to the relevant description in the foregoing, which is not described here again.

[0172] It should be noted that the beam information can also be referred to as TCI state information. The TCI state information includes at least one of the following: an identifier, an 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.

[0173] Optionally, the angle information comprises at least one of an angle of arrival or an angle of departure of the reference signal for each propagation path between the terminal device and the access network device. Optionally, the angle of arrival for each propagation path comprises at least one of a horizontal angle of arrival for each propagation path or a vertical angle of arrival for each propagation path. The angle of departure for each propagation path comprises at least one of a horizontal angle of departure for each propagation path or a vertical angle of departure for each propagation path. For example, as shown in FIG. 5, the angle information can comprise a horizontal angle of arrival a1, a vertical angle of arrival b1, a horizontal angle of departure c1, and a vertical angle of departure d1 for path 1, a horizontal angle of arrival a2, a vertical angle of arrival b2, a horizontal angle of departure c2, and a vertical angle of departure d2 for path 2, a horizontal angle of arrival a3, a vertical angle of arrival b3, a horizontal angle of departure c3, a vertical angle of departure d3 for path 3, a horizontal angle of arrival a4, a vertical angle of arrival b4, a horizontal angle of departure c4, and a vertical angle of departure d4 for path 4.

[0174] It should be noted that the above is an example of taking the propagation path between the terminal device and the access network device as the NLOS path. In fact, the propagation path between the terminal device and the access network device can also comprise a LOS path between the terminal device and the access network device, which is not limited in the present application.

[0175] Optionally, the terminal device measures the reference signal of the access network device to obtain the 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 according to the reference signal to obtain a channel power delay profile; and the terminal device determines the propagation path information according to the channel power delay profile. Specifically, the terminal device takes the number of power peaks greater than a threshold value in the channel power delay profile as the number of propagation paths between the terminal device and the access network device. Alternatively, the terminal device takes 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, as shown in FIG. 5, the terminal device receives the reference signal from the access network device through beams 1 to 4. Then, the terminal device performs channel estimation according to the reference signal to obtain a channel PDP. As shown in FIG. 6A, the terminal device obtains curve 1 shown in FIG. 6A for the reference signal received through beam 1, obtains curve 2 shown in FIG. 6A for the reference signal received through beam 2, obtains curve 3 shown in FIG. 6A for the reference signal received through beam 3, and obtains curve 4 shown in FIG. 6A for the reference signal received through beam 4. As shown in FIG. 6B, it is a schematic diagram of the combination of curves 1 to 4. The terminal device can determine that there are four power peaks greater than the threshold value, i.e., points A, B, C and D, through FIG. 6B. Therefore, the terminal device can determine that there are four propagation paths between the terminal device and the access network device, i.e., paths 1 to 4. Alternatively, the terminal device can determine that there are four sensing targets or sensing reflectors, i.e., 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 and the angle information of paths 1 to 4 between the terminal device and the access network device.

[0176] It should be noted that the propagation path information can also be referred to as multi-path information, direction information, path information, or first information, and the name of the propagation path information is not limited in the present application.

[0177] Optionally, the beam information and the angle information can also be sent separately, i.e., not carried in the propagation path information.

[0178] Optionally, before step 402, the sensing management function interacts with the access network device to enable the sensing management function to determine that the access network device has sensing capability. Optionally, the sensing management function can 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 can include: the identification of the sensing reference signal used for sensing, and / or the information of the beam used to transmit the sensing reference signal.

[0179] 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.

[0180] Optionally, the embodiment shown in FIG. 4 further includes step 401a. Step 401a can be performed before step 401.

[0181] 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.

[0182] 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.

[0183] Optionally, the first request further includes threshold information, which is used to determine the number of propagation paths between the terminal device and the access network device.

[0184] In one possible implementation, the threshold information includes at least one threshold value. For example, the threshold information includes one threshold value. The terminal device receives reference signals from the access network device through multiple beams, and performs channel estimation based on the reference signals to obtain a PDP. Then, the terminal device determines the number of power peaks higher than the threshold value based on the channel PDP, to determine the number of propagation paths between the terminal device and the access network device.

[0185] Optionally, the threshold information further includes a sensing target type corresponding to each threshold value in the at least one threshold value. Optionally, the sensing target type includes a drone, a building, a bridge, or a car, etc. That is, different threshold values correspond to different sensing target types, which is conducive to accurate sensing of the environment.

[0186] Optionally, the at least one threshold value can be determined according to at least one of the following: a communication link between the terminal device and the access network device, a transmission power of the reference signal transmitted by the access network device, a frequency point, a wavelength, a path loss, or a distance between the terminal device and the access network device.

[0187] 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 the present application.

[0188] The first request in step 401a includes threshold information is only one possible implementation. Alternatively, the threshold information can be pre-configured in the terminal device, or determined by the terminal device itself, which is not limited in the present application.

[0189] Alternatively, the first request is a sensing measurement request, or a sensing request, or a measurement request, which is not limited in the present application. Correspondingly, the propagation path information in step 403 can be carried in a sensing measurement response, a sensing response, or a measurement response.

[0190] Alternatively, the embodiment shown in FIG. 4 further includes steps 404 and 405. Steps 404 and 405 can be performed after step 403.

[0191] 404. The access network device determines the sensing reference signal resource configuration information according to the propagation path information.

[0192] The sensing reference signal resource configuration information is used to configure at least one sensing reference signal resource.

[0193] In one possible implementation, the at least one sensing reference signal resource is a path-level sensing reference signal resource. Specifically, the path-level sensing reference signal resource can be represented as: the reference signal associated with the spatial information contained in the sensing reference signal resource configuration information is a path-level reference signal, which can be understood as a certain path corresponding to the reference signal, which can be the strongest path, the first path, or the second strongest path, etc. The terminal device transmits the reference signal through the sensing reference signal resource, and correspondingly, the access network device receives the reference signal from the terminal device and measures the reference signal to determine a certain propagation path, thereby determining the associated spatial information, such as beam, angle information, etc. For example, the sensing reference signal resource is an SRS resource, and the SRS resource is a path-level sensing reference signal resource. As described above, the SRS spatial correlation information (SRS-SpatialRelationInfoPos) includes the reference signal identifier associated with the SRS resource. The reference signal corresponding to the reference signal identifier is a path-level reference signal.

[0194] In another possible implementation, the at least one sensing reference signal resource is a beam-level sensing reference signal resource. Specifically, the beam-level sensing reference signal resource can be represented as: the reference signal associated with the spatial information included in the sensing 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 the reference signal. The terminal device transmits the reference signal through the beam associated with the sensing reference signal resource on the sensing reference signal resource, and 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 sensing reference signal resource is an SRS resource, and the SRS resource is a beam-level sensing reference signal resource. As described above, the SRS spatial correlation information includes the reference signal identifier associated with the SRS resource. The reference signal corresponding to the reference signal identifier is a beam-level reference signal.

[0195] 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.

[0196] Optionally, the step 405 can also be described as: the access network device configures the terminal device with the at least one sensing reference signal resource.

[0197] It should be noted that the access network device can also send the sensing reference signal resource configuration information to the core network device. Correspondingly, the core network device receives the sensing reference signal resource configuration information from the access network device.

[0198] Optionally, the sensing reference signal resource configuration information is carried in an RRC message.

[0199] Optionally, the embodiment shown in FIG. 4 further includes steps 406 to 408. The steps 406 to 408 can be executed after the step 405.

[0200] 406. The terminal device sends the sensing reference signal to the access network device through the at least one sensing reference signal resource. Correspondingly, the access network device receives the sensing reference signal from the terminal device.

[0201] In one possible implementation, the at least one sensing reference signal resource is a path-level sensing reference signal resource. As shown in FIG. 5, each path in the paths 1 to 4 corresponds to a sensing reference signal resource. The terminal device sends the sensing reference signal to the access network device through the sensing reference signal resource corresponding to each path. Correspondingly, the access network device receives the sensing reference signal from the terminal device.

[0202] Therefore, the access network device can configure appropriate sensing reference signal resources for the terminal device in combination with the propagation path information. Thus, the accuracy of the access network device measuring the sensing reference signal is improved, and the sensing accuracy of the environment is improved.

[0203] Optionally, the embodiment shown in FIG. 4 further includes step 406a. Step 406a can be performed before step 406.

[0207] 407. The access network device measures the sensing reference signal to obtain a sensing measurement result.

[0208] In one possible implementation, the sensing reference signal is carried in at least one sensing reference signal resource. The at least one sensing reference signal resource is a path-level sensing reference signal resource. The sensing measurement result can include the time delay, energy, angle of arrival (e.g., horizontal angle of arrival and / or vertical angle of arrival), and / or phase of multiple propagation paths measured by the access network device from the sensing reference signal.

[0209] In another possible implementation, the sensing reference signal is carried in at least one sensing reference signal resource. The at least one sensing reference signal resource is a beam-level sensing reference signal resource. The sensing measurement result can include the time delay, energy, angle of arrival (e.g., horizontal angle of arrival and / or vertical angle of arrival), and / or phase of the first path or target path corresponding to the sensing reference signal measured by the access network device.

[0210] 408. The access network device sends the sensing measurement result to the sensing management function. Correspondingly, the sensing management function receives the sensing measurement result from the access network device.

[0211] Optionally, the sensing measurement result is carried in a sensing measurement response, or a sensing response, or a measurement response, which is not limited in the present application.

[0212] In the embodiments of the present application, the terminal device measures the reference signal from the access network device to obtain the propagation path information. 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, corresponding beam information, or corresponding angle information. Then, the terminal device sends the propagation path information to the access network device. Thus, the access network device obtains the propagation path information between the terminal device and the access network device, which is beneficial to the access network device to accurately perceive the environment, improve the resolution of different perception targets, and improve the perception accuracy.
