[0086] Embodiments of the present application provide an information sending method, an information receiving method, and related apparatuses, configured for a terminal device to send at least one of the following: beam information or time information to an access network device or a sensing management function. This facilitates the transmission of sensing reference signals by the terminal device using at least two beams when sensing reference signal resources are limited, enabling the access network device to sense sensing targets in at least two beam directions, thereby improving sensing accuracy and reducing the overhead of sensing reference signal resources.

[0087] References to "one embodiment" or "some embodiments" in this application mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the application. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0088] In the description of this application, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" in this article is merely a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, "at least one" means one or more, and "plurality" means two or more. "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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] When using base stations for perception, there is a problem of limited coverage. The base station can only effectively perceive and detect strongly reflective targets within the visible area. As shown in Figure 1, for the base station, the perception area is divided into the line-of-sight (LOS) area and the non-line-of-sight (NLOS) area. Due to the obstruction of obstacles, it is impossible to effectively perceive the targets in the NLOS area. For the NLOS area, terminal devices can be introduced to assist the base station in perception. For example, as shown in Figure 2, the terminal device assists the base station in realizing perception of the environment. Specifically, the base station sends a perception reference signal, which is reflected by the reflector and then reflected by the cylinder to the terminal device. The terminal device can measure the perception reference signal to obtain a perception measurement result. Both reflectors and cylinders can be considered as perception targets. If there are multiple perception targets that need to be detected, different beams need to be used to send the perception reference signal to improve the detection accuracy of the perception targets.

[0093] 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.

[0094] FIG3A is a schematic diagram of a communication system according to an embodiment of the present application. Referring to FIG3A , 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.

[0095] Terminal device 301 communicates with an access network device (such as gNB 302 or ng-eNB 303 in FIG. 3A ) via the Uu interface. ng-eNB 303 is an access network device in a long-term evolution (LTE) communication system, and gNB 302 is an access network device in a new radio (NR) communication system. In this communication system, access network devices communicate with each other via the Xn interface, and the access network device and AMF 304 communicate with each other via the NG-C interface. AMF 304 and LMF 305 communicate with each other via the NL1 interface, with AMF 304 acting as a router for communication between the access network device and LMF 305. LMF 305 is a network element, module, or component in the new radio (NR) core network that provides positioning capabilities for terminal devices. LMF 305 is used to calculate the location of the terminal device. SMF 306 can store environmental maps and reconstruct environmental maps, and it interacts with LMF 305 to exchange environmental, measurement, and other information.

[0096] In the communication system shown in FIG3A above, 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. For example, as shown in FIG3B, LMF305 and SMF306 are deployed or integrated together to become a network element, which provides perception and positioning functions.

[0097] Figures 3A and 3B above illustrate only an example of a communication system including two access network devices, a gNB and an ng-eNB. In actual applications, the communication system may include at least one access network device, which is not specifically limited in this application.

[0098] In the present application, in the communication systems shown in Figures 3A and 3B above, 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 referred to as a positioning device, positioning center, positioning server, positioning management device, or positioning management function device. This application does not specifically limit the name of LMF. In current or future communication systems, any functional network element with a function similar to LMF 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.

[0099] In the present application, in the communication systems shown in FIG. 3A and FIG. 3B , the name of the SMF may change as the communication system evolves. As long as a functional network element with other names having functions similar to those of the SMF can be understood as the SMF of the present application, and is applicable to the method provided in the present 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 of SMF to introduce the execution operation of the functional network element.

[0100] 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 an LTE communication system. A fifth generation communication system may include an 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.

[0101] The following introduces the terminal equipment, access network equipment, perception management function, and positioning management function involved in this application.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] 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 obtained by integrating two or more of the above communication systems.

[0106] 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 (e.g., home evolved NodeB, or home Node B, HNB), baseband unit (BBU), access point (AP) in a wireless fidelity (WIFI) system, macro base station, micro base station, wireless relay node, donor node, wireless controller in a CRAN scenario, wireless backhaul node, transmission point (TP), or transmission and reception point (TRP), etc. It may also be access network equipment in a 5G mobile communication system. For example, a next generation NodeB (gNB), TRP, or TP in an 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 equipment may 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), etc. The CU and DU can be set separately, or can also be included in the same network element, such as 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). Alternatively, the access network device can also be a server, a wearable device, a vehicle, or an on-board device, etc. For example, the access network device in the 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 on 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 that performs the corresponding communication function.The TRP also contains program instructions for corresponding communication functions.

[0107] 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.

[0108] Optionally, for network elements in the ORAN system, each network element may implement the protocol layer functions shown in Table 1 below.

[0109] Table 1

[0110] 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.

[0111] 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.

[0112] 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.).

[0113] 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] The positioning management function is used to provide positioning function to realize the positioning of terminal devices.

[0121] In order to facilitate understanding of the technical solution of this application, some technical terms involved in this application are introduced below.

[0122] 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.

[0123] 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.

[0124] 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 domain 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.

[0125] A beam used to receive a signal may 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 may 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, an uplink beam may also be replaced by an SRS resource.

[0126] 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.

[0127] 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.

[0128] 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.

[0129] 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.

[0130] 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.

[0131] 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.

[0132] 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.

[0133] 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:

[0134] 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:

[0135] The network device indicates a downlink TCI state to the terminal device through DCI. The terminal device determines that the type of the downlink TCI state is the reference signal resource in the QCL information of typeD. 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.

[0136] 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:

[0137] The specific steps are as follows:

[0138] 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.

[0139] The following describes the configuration, activation and indication of TCI status.

[0140] 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.

[0141] TCI-state activation: After the network device is configured with multiple TCI-states, it is also necessary to activate 8 of them through the media access control control element (MAC CE). These 8 TCI-states correspond one-to-one to the 8 values ​​of the TCI field in the DCI. That is, the 8 values ​​of the TCI field in the DCI correspond to which 8 TCI-states are determined by the MAC CE. The media access control control element can also be called the media access control control element.

[0142] 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.

[0143] It should be noted that the three descriptions of TCI state, TCI-state and TCI state in this article can be used interchangeably.

[0144] In this application, the perception reference signal can be an 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.

[0145] A possible configuration of the perception reference signal resource is described below, taking the perception reference signal resource as an SRS resource.

[0146] The configuration of spatialRelationInfoPos-r16 is as follows:

[0147] The SRS spatial correlation positioning information (SRS-SpatialRelationInfoPos) in the above-mentioned SRS resource includes a reference signal identifier associated with the SRS resource. As can be seen from the above configuration, optionally, the SRS resource is associated with a synchronization signal-broadcast channel measurement resource block (synchronization signal and physical broadcast channel block, SS / PBCH block, SSB for short) index. The SSB index corresponds to a certain SSB, and the SSB configuration includes spatial parameters for sending the SSB, which can also be called a beam. In other words, 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. Specifically, the reference signal can be referred to as the reference signal corresponding to the beam.

[0148] 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 this application.

[0149] It can be seen that one perception reference signal resource corresponds to one beam, that is, the terminal device sends a perception reference signal through the corresponding beam on the perception reference signal resource. For the base station, the base station receives the perception reference signal and measures the perception reference signal to obtain a perception measurement result. It can be seen that the base station can perceive the beam direction corresponding to the beam through the perception reference signal, but cannot perceive other beam directions. Therefore, when using the base station for environmental perception, if the perception reference signal resources of the base station are limited, if there are not enough perception reference signal resources for the terminal device to send perception reference signals in different beam directions, for example, the number of perception reference signal resources configured by the base station for the terminal device is less than the number of perception targets, then how to perceive the perception targets in different beam directions is an urgent problem to be solved.

[0150] This application provides a corresponding technical solution in which a terminal device sends at least one of the following to an access network device or a sensing management function: beam information or time information. This facilitates the transmission of sensing reference signals via at least two beams when sensing reference signal resources are limited, enabling the access network device to sense sensing targets in at least two beam directions.

[0151] In this application, the perception reference signal resource may also be referred to as a perception resource, or a perception measurement resource, or a measurement resource, etc., which is not specifically limited in this application.

[0152] 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.

[0153] The following describes the technical solution of this application in conjunction with specific embodiments. In this application, the terminal device sends beam information and / or time information to the access network device, which can be specifically described in the embodiment shown in Figure 4. Alternatively, the terminal device sends beam information and / or time information to the perception management function, which can be specifically described in the embodiment shown in Figure 9.

[0154] FIG4 is a schematic diagram of an embodiment of the information sending method and the information receiving method of the present application. Referring to FIG4 , the method includes the following steps.

[0155] It should be noted that, in the embodiment shown in FIG4 , the method is illustrated by taking the terminal device, access network device, and perception management function as the execution subjects of the interaction diagram as an example, but the present application does not limit the execution subjects of the interaction diagram. For example, in the embodiment shown in FIG4 , the execution subject in steps 401a, 401, 402, and 403 is the terminal device. The execution subject may also be a chip, chip system, or processor that supports the terminal device to implement the method, or a logic module or software that can implement all or part of the terminal device functions. In the embodiment shown in FIG4 , the execution subject in steps 401a, 402, 403, 404, 404a, and 405 is the access network 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. In the embodiment shown in FIG4 , the execution subject in steps 404a and 405 is the perception management function. The execution subject may also be a chip, chip system, or processor that supports the perception management function to implement the method, or a logic module or software that can implement all or part of the perception management function.

[0156] 401. The terminal device determines at least one of the following: beam information or time information.

[0157] The beam information is information about at least two beams used by the terminal device to send the perception reference signal. The time information is time information when the terminal device uses at least two beams to send the perception reference signal.

[0158] In one possible implementation, the terminal device determines, based on prior data, beam management, and / or beam calibration, to use at least two beams to transmit the perception reference signal. For example, as shown in FIG5A , the terminal device determines, based on beam management, to transmit the perception reference signal via four beams (beams 1 to 4). This facilitates the access network device to perceive the beam directions corresponding to the four beams based on the perception reference signal, thereby enabling perception of perception targets 1 to 4.

[0159] In another possible implementation, the terminal device measures the first reference signal from the access network device through multiple beams to determine one or more propagation paths between the terminal device and the access network device; each propagation path in the one or more propagation paths corresponds to one or more beams, and the one or more beams belong to the multiple beams. The terminal device uses the information that each propagation path in the one or more propagation paths corresponds to one or more beams as beam information. Optionally, one propagation path corresponds to one or more beams, or one beam corresponds to one or more propagation paths. For example, as shown in Figure 5A, the terminal device receives the first reference signal from the access network device through beam 1 and measures the first reference signal to determine path 1, so path 1 corresponds to beam 1. The terminal device receives the first reference signal from the access network device through beam 2 and measures the first reference signal to determine path 2, so path 2 corresponds to beam 2. The terminal device receives the first reference signal from the access network device through beam 3 and measures the first reference signal to determine path 3, so path 3 corresponds to beam 3. The terminal device receives the first reference signal from the access network device through beam 4, and measures the first reference signal to determine path 4, so path 4 corresponds to beam 4.

[0160] Specifically, the terminal device performs channel estimation based on the first reference signal to obtain a channel power delay profile; the terminal device determines the one or more propagation paths based on the channel power delay profile (PDP). Optionally, the terminal device uses the number of power peaks greater than a threshold value in the channel PDP as the number of propagation paths in the one or more propagation paths. Alternatively, the terminal device uses the number of power peaks greater than or equal to the threshold value in the channel PDP as the number of propagation paths between the terminal device and the access network device.

[0161] For example, as shown in Figure 5A, the terminal device receives a first reference signal from the access network device via beams 1 to 4. The terminal device then performs channel estimation based on the first reference signal to obtain the channel PDP. As shown in Figure 5B, the terminal device obtains curve 1 (Figure 5B) for the first reference signal received via beam 1, curve 2 (Figure 5B) for the first reference signal received via beam 2, curve 3 (Figure 5B) for the first reference signal received via beam 3, and curve 4 (Figure 5B) for the first reference signal received via beam 4. Figure 5C shows a schematic diagram of the synthesis of curves 1 to 4. Based on Figure 5C, the terminal device can determine the presence of four power peaks greater than a 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 may determine information of beams 1 to 4 as the beam information.

[0162] Optionally, the first reference signal may be a CSI-RS, a positioning reference signal (PRS), an SSB, a DMRS, a PTRS, or other reference signals, which is not specifically limited in this application.

[0163] Optionally, the beam information includes at least one of the following: an index, identifier, angle, or associated reference signal information corresponding to the at least two beams. For example, as shown in FIG5A , the at least two beams include beams 1 to 4. The beam information may include an index corresponding to beams 1 to 4, respectively.

[0164] Optionally, the angles corresponding to the at least two beams include at least one of the following: the horizontal arrival angle, vertical arrival angle, horizontal departure angle, or vertical departure angle corresponding to the at least two beams. For example, as shown in FIG5A , the angles corresponding to the at least two beams 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.

[0165] Optionally, the reference signal information associated with the at least two beams includes at least one of the following: an identifier, index, type, or indication of the reference signals associated with the at least two beams. Optionally, the reference signal type includes: SSB, PRS, CSI-RS, or SRS. As described above regarding perceptual reference signal resources, an association exists between beams and reference signals, and each beam has an associated reference signal. The beam information may also include identifiers of reference signals associated with beams 1 to 4, respectively.

[0166] It should be noted that in this application, beam can also be referred to as TCI state, that is, beam information can also be referred to as TCI state information. Specifically, this application does not limit the name of beam information. TCI state information is information about at least two TCI states used by the terminal device to send a perception reference signal.

[0167] Optionally, the time information includes at least one of the following: a transmission period, a switching period, a transmission time interval, or a switching time interval. The transmission period is a period during which the terminal device uses the at least two beams to transmit the perception reference signal. The switching period is a period during which the terminal device switches the beam used to transmit the perception reference signal within a transmission period. The transmission time interval is a time interval during which the terminal device uses the at least two beams to transmit the perception reference signal. The switching time interval is a time interval during which the terminal device switches the beam used to transmit the perception reference signal within a transmission period or a transmission time interval. The transmission period can also be replaced by a transmission time interval or a transmission time interval. The switching period can also be replaced by a switching time interval or a switching time interval. For example, as shown in FIG6 , the perception reference signal resource is configured by the access network device for the terminal device. The perception reference signal resource is a periodic resource, and the perception reference signal resource includes multiple resource blocks. As shown in FIG6 , in the perception reference signal resource, the time interval between two adjacent resource blocks (for example, resource block 1 and resource block 2 shown in FIG6 ) is 160 ms (milliseconds). Therefore, it can be seen that the period of the perception reference signal resource is 160 ms. The terminal device uses beam 1 to send the perception reference signal on resource block 1, uses beam 2 to send the perception reference signal on resource block 2, uses beam 3 to send the perception reference signal on resource block 3, uses beam 4 to send the perception reference signal on resource block 4, and so on. Therefore, the transmission period of the perception reference signal sent by the terminal device using beams 1 to 4 is 640ms.

[0168] In one possible implementation, the switching period is equal to the period of the sensing reference signal resource. For example, as shown in FIG6 , the period of switching the beam used to transmit the sensing reference signal by the terminal device within a transmission period is 160 ms, which is equal to the period of the sensing reference signal resource.

[0169] In another possible implementation, the switching period is twice the period of the sensing reference signal resource. For example, as shown in FIG7 , the period for switching the beam used to transmit the sensing reference signal by the terminal device within a transmission period is 320 ms, which is twice the period of the sensing reference signal resource.

[0170] Optionally, the time information also includes the number of times the terminal device uses each beam to send the perception reference signal in one transmission cycle. In other words, the time information also includes the number of resource blocks occupied by the terminal device using each beam to send the perception reference signal in one transmission cycle. For example, as shown in Figure 7, the terminal device uses beam 1 and beam 2 to send the perception reference signal. In one transmission cycle, the number of times the terminal device uses beam 1 to send the perception reference signal is 1, and the number of times the terminal device uses beam 2 to send the perception reference signal is 1. For another example, as shown in Figure 8, the terminal device uses beam 1 and beam 2 to send the perception reference signal. In one transmission cycle, the number of times the terminal device uses beam 1 to send the perception reference signal is 2, and the number of times the terminal device uses beam 2 to send the perception reference signal is 2.

[0171] 402. The terminal device sends at least one of the following to the access network device: beam information or time information. Correspondingly, the access network device receives at least one of the following from the terminal device: beam information or time information.

[0172] Optionally, beam information and time information can be sent together or separately, which is not limited in this application.

[0173] Optionally, before step 402, the perception management function interacts with the access network device to enable the perception management function to determine whether the access network device has perception capabilities. Optionally, the perception management function may send a perception information request to the access network device. The perception information request is used to request the access network device to report perception-related information. The access network device reports the perception-related information and the location information of the access network device to the perception management function. For example, the perception-related information may include: an identifier of a perception reference signal used for perception.

[0174] Optionally, the beam information and time information are carried in a sensing information response or a sensing response, which is not specifically limited in this application. Optionally, the embodiment shown in FIG4 further includes step 401a. Step 401a can be performed before step 402.

[0175] 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.

[0176] The first request is used to request the terminal device to use different beams to send perception reference signals on different time domain resources; or, the first request is used to request the terminal device to use time division to send perception reference signals; or, the first request is used to request the terminal device to use different beams to send perception reference signals at different times; or, the first request is used to request the terminal device to perform time division transmission of perception reference signals; or, the first request is used to request the terminal device to use time division to send perception reference signals through different beams. For example, as shown in FIG6 , the perception reference signal resources are configured by the access network device for the terminal device, and the access network device requests the terminal device to use different beams to send perception reference signals on different resource blocks included in the perception reference signal resources or different time domain resources occupied by the perception reference signal resources.

[0177] Optionally, the first request is used to request reporting of beam information and / or time information.

[0178] Optionally, the first request is a sensing measurement request (sensing information request) or a sensing request, which is not specifically limited in this application.

[0179] Optionally, the embodiment shown in FIG4 further includes steps 403 and 404. Steps 403 and 404 may be performed after step 402.

[0180] 403. The terminal device sends a perception reference signal to the access network device through at least two beams according to the beam information and / or time information. Correspondingly, the access network device receives the perception reference signal from the terminal device.

[0181] Optionally, the time information includes a transmission period and a switching period, and the terminal device sends the perception reference signal to the access network device through the at least two beams according to the transmission period. Within a transmission period, the terminal device switches the beam used for sending the perception reference signal according to the switching period, and sends the perception reference signal through the switched beam.

[0182] For example, as shown in Figure 6, the terminal device uses beams 1 to 4 to send perception reference signals to the access network device with a transmission period of 640ms. Within a transmission period, the terminal device switches the beam used to send perception reference signals with a period of 160ms. As shown in Figure 6, the terminal device uses beam 1 to send perception reference signals to the access network device on resource block 1, uses beam 2 to send perception reference signals to the access network device on resource block 2, uses beam 3 to send perception reference signals to the access network device on resource block 3, and uses beam 4 to send perception reference signals to the access network device on resource block 4.

[0183] For another example, as shown in Figure 7, the terminal device uses beam 1 to beam 2 with a transmission period of 640ms to send a perception reference signal to the access network device. Within one transmission period, the terminal device uses a period of 320ms to switch the beam used to send the perception reference signal. As shown in Figure 7, the terminal device uses beam 1 to send a perception reference signal to the access network device on resource block 1, does not send a perception reference signal on resource block 2, uses beam 2 to send a perception reference signal to the access network device on resource block 3, and does not send a perception reference signal on resource block 4. Alternatively, as shown in Figure 8, the terminal device uses beam 1 to send a perception reference signal to the access network device on resource block 1 and resource block 2, and uses beam 2 to send a perception reference signal to the access network device on resource block 3 and resource block 4.

[0184] It should be noted that the execution order between the above steps 402 and 403 is not limited. Step 402 can be executed first, and then step 403; or, step 403 can be executed first, and then step 402; or, steps 402 to 403 can be executed at the same time. This application does not make any specific restrictions.

[0185] 404. The access network device measures the perception reference signal according to the beam information and / or time information to obtain a perception measurement result.

[0186] Specifically, the access network device measures the perception reference signal through at least one perception reference signal according to the beam information and / or time information to obtain a perception measurement result. The perception measurement result includes at least one of the following: delay, energy, arrival angle (for example, horizontal arrival angle and / or vertical arrival angle), or phase corresponding to one or more propagation paths. For example, as shown in FIG5A , the beam information may include indexes corresponding to beams 1 to 4, respectively, and the time information includes a transmission period and a switching period. As shown in FIG6 , the transmission period is 640 ms and the switching period is 160 ms. Combining FIG5A and FIG6 , it can be seen that the access network device receives the perception reference signal sent by the terminal device through beam 1 on resource block 1, receives the perception reference signal sent by the terminal device through beam 2 on resource block 2, receives the perception reference signal sent by the terminal device through beam 3 on resource block 3, and receives the perception reference signal sent by the terminal device through beam 4 on resource block 4. Then, the access network device measures the perception reference signal to obtain a perception measurement result. For example, as shown in FIG5A , the perception measurement results may include the time delay, energy, angle of arrival, and / or phase corresponding to paths 1 to 4, respectively. In other words, the perception measurement results may include the time delay, energy, angle of arrival, and / or phase corresponding to the first path or target path in the beam direction corresponding to beams 1 to 4, respectively.

[0187] As can be seen, the terminal device uses time division to send perception reference signals using different beams on different time domain resources, and reports beam information and / or time information to the access network device. This helps the access network device complete environmental perception in the directions corresponding to different beams, improves the access network device's perception performance, avoids the network from configuring too many perception reference signal resources, and saves the overhead of perception reference signal resources.

[0188] The access network device measures the perception reference signal based on the beam information and / or time information, thereby ensuring the accuracy of the access network device's measurement of the perception reference signal, which is conducive to perceiving and distinguishing perception targets in multiple beam directions in the environment, thereby improving perception accuracy. Furthermore, it is conducive to avoiding the access network device from performing some unnecessary measurements and reducing measurement overhead. For example, as shown in FIG5A, the terminal device uses a time-division method to send perception reference signals through beams 1 to 4 respectively. The access network device can measure the perception reference signal in the corresponding beam direction without having to measure the perception reference signal in all directions, thereby reducing measurement overhead. For another example, as shown in FIG7, the terminal device uses a time-division method to send perception reference signals through beams 1 and 2 respectively. As shown in FIG7, the terminal device uses beam 1 to send the perception reference signal to the access network device on resource block 1, and does not send the perception reference signal on resource block 2. The terminal device uses beam 2 to send the perception reference signal to the access network device on resource block 3, and does not send the perception reference signal on resource block 4. Therefore, the access network device can measure the perception reference signal in the direction of beam 1 in resource block 1 and measure the perception reference signal in the direction of beam 2 in resource block 3. The access network device does not need to measure the perception reference signal in resource blocks 2 and resource blocks 4, thereby reducing measurement overhead.

[0189] It should be noted that, if step 403 is performed before step 402, the above step 404 can be replaced by the description as: the access network device measures the perception reference signal to obtain a perception measurement result.

[0190] The examples in the above embodiments are based on the example of an access network device configuring one sensing reference signal resource for a terminal device. In actual applications, the access network device may configure one or more sensing reference signal resources for the terminal device, where the number of configured sensing reference signal resources is less than the number of sensing targets. For example, as shown in FIG5A , if there are four sensing targets and the access network device configures fewer than four sensing reference signal resources for the terminal device, the terminal device and the access network device may implement the technical solution of this application to achieve sensing of the four sensing targets.

[0191] Optionally, the embodiment shown in FIG4 further includes step 405 , which may be performed after step 404 .

[0192] 405. 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.

[0193] Optionally, the perception measurement result is carried in a perception measurement response, or a perception response, which is not specifically limited in this application.

[0194] Optionally, the embodiment shown in FIG4 further includes step 404a. Step 404a may be performed before step 405.

[0195] 404a: The perception management function sends a third request to the access network device. Correspondingly, the access network device receives the third request from the perception management function.

[0196] The third request is used to request the access network device to sense the environment. Optionally, the third request is a perception measurement request or a perception request, which is not specifically limited in this application.

[0197] In an embodiment of the present application, the terminal device determines at least one of the following: beam information or time information. The beam information is information about at least two beams used by the terminal device to send a perception reference signal. The time information is time information when the terminal device uses at least two beams to send a perception reference signal. Then, the terminal device sends at least one of the following to the access network device: beam information or time information. This facilitates the access network device to determine the beam information and time information used by the terminal device to send a perception reference signal, and facilitates the terminal device to send a perception reference signal through at least two beams when the perception reference signal resources are limited, so as to enable the access network device to perceive the perception targets in at least two beam directions, improve perception accuracy, and save the overhead of perception reference signal resources.
