[0002] For sensing services, the location or shape of a target in the environment can be sensed by utilizing the reflection, scattering, or diffraction of signals transmitted by user equipment (UE) or base stations as they propagate through space. Taking a scenario where both the UE and base station participate in sensing as an example, the UE can measure the signals reflected, scattered, or diffracted by the target and report the measurement results to the base station, which then realizes the sensing of the target. Improving sensing performance is currently a hot research topic. Summary of the Invention

[0003] This application provides a communication method and apparatus to improve sensing performance. This communication method and apparatus may also be referred to as a sensing method and apparatus, or an integrated communication and sensing method and apparatus.

[0004] Firstly, this application provides a communication method applicable to a terminal device. The terminal device is, for example, a terminal equipment, or a component within a terminal equipment, such as a communication module, circuitry or chip responsible for communication functions (e.g., a modem chip, also known as a baseband chip, or a system-on-a-chip (SoC) chip containing a modem core, a system-in-package (SIP) chip, a chip system, or a processor, etc.) or other functional module applicable to the terminal equipment. This chip (or chip system) or functional module can implement the functions of the terminal equipment. For example, if the chip (or chip system) or other functional module is disposed within the terminal equipment, it can also be a logic module or software capable of implementing all or part of the functions of the terminal equipment.

[0005] The method may include: receiving a sensing signal; and sending first information; wherein the first information is related to a first oversampling factor, and the first information is used to indicate a first angle of a first sensing target in a first dimension, the angular resolution of the first angle being lower than the angular resolution of a second angle; or, the first information is related to a first oversampling factor and a second oversampling factor, and the first information is used to indicate a second angle of the first sensing target in a first dimension.

[0006] Optionally, the angular resolution of the first angle being lower than (or less than) the angular resolution of the second angle can be replaced with: the resolution of the second angle being higher than (or greater than) the angular resolution of the first angle; or replaced with: the minimum spacing between adjacent angles of the first angle being greater than the minimum spacing between adjacent angles of the second angle; or replaced with: the minimum spacing between adjacent angles of the second angle being less than the minimum spacing between adjacent angles of the first angle.

[0007] Using the above method, the terminal device can feed back the angle information (such as a first angle or a second angle) of the first sensing target in the first dimension to the access network device. This allows the access network device to use the angle information of the first sensing target in the first dimension to perceive the first sensing target (such as obtaining the position and distance of the first sensing target), which is beneficial to improving sensing performance. In addition, when the first information is related to two oversampling factors, the first information can be used to indicate a second angle with high angular resolution, allowing the access network device to obtain a more accurate sensing result using the second angle, thereby improving sensing performance.

[0093] The relevant terms used in the embodiments of this application will be explained below. It should be noted that these explanations are for the purpose of making the embodiments of this application easier to understand, and should not be regarded as a limitation on the scope of protection claimed by this application.

[0094] I. Sensing, sensing signals, communication signals, echo signals, communication-sensing fusion signals, and targets:

[0095] 1) Perception can also be replaced with: detection, sensing process, sensing operation, sensing detection, detection processing, executing perception, running perception, executing perception service, or running perception service, etc.

[0096] Perception can be understood as a technology capable of acquiring information about the characteristics of the environment and / or objects within it. This information includes, but is not limited to, shape, size, orientation, speed, position, distance between objects, or relative motion. The working principle of perception is as follows: the transmitting end sends a perception signal, and the receiving end receives the perception signal (also called the echo signal) after it has passed through the sensing target (or through scattering, diffraction, or diffusion). Based on the received perception signal, the sensing result is obtained, such as speed, distance, shape, and size.

[0097] 2) Sensing signal: A signal used to sense (or detect) a target (or object) or its surrounding environment. For example, a sensing signal can be a signal transmitted over an air interface and used to sense a target or its surrounding environment. Optionally, a sensing signal can also be called a signal used for sensing, a sensing reference signal, a reference signal used for sensing, a detection signal, a linear frequency modulated signal, a radar signal, a radar sensing signal, a radar detection signal, or an environmental sensing signal, etc. Optionally, a sensing signal can be a pulse signal or a signal in a wireless communication system (or sensing system).

[0098] In one example, the sensing signal can be any of the following: channel state information-reference signal (CSI-RS), synchronization signal block (SSB), positioning reference signal (PRS), sounding reference signal (SRS), sensing reference signal, demodulation reference signal (DMRS), physical random access channel (PRACH), or service request (SR) signal. The SRS can be a multi-input multi-output (MIMO) SRS or a positioning SRS, etc.

[0099] It should be understood that this application does not limit the implementation form of the sensing signal.

[0100] 3) Communication signals can be signals transmitted between communication devices for communication purposes. Optionally, these communication signals can carry communication data information, communication control information, or be used for communication measurement, without limitation. For example, communication signals may include signals transmitted between network devices and terminal devices. Communication signals may be carried, for example, on a physical downlink shared channel (PDSCH), a physical uplink shared channel (PUSCH), a physical downlink control channel (PDCCH), or a physical uplink control channel (PDCCH), or a physical random access channel (PRACH); or, for example, on SR, CSI-RS, SRS, or DMRS.

[0101] 4) Echo signals can be understood as signals generated by the reflection (scattering, diffraction, or diffusion) of a sensing signal by the target. Echo signals, or a combination of echo and sensing signals, can reflect target parameters. For example, the time delay of the echo signal relative to the transmitted sensing signal can reflect the target's distance from the transmitter. For example, the Doppler shift of the echo signal relative to the sensing signal can reflect the target's velocity. For example, the phase difference between multiple echo signals can reflect the target's angle.

[0102] 5) Communication-sensing fusion signal can be understood as a signal used for both communication and sensing, or as a signal that multiplexes a communication signal for sensing. Optionally, the communication-sensing fusion signal can also be called a synsensory-sensing fusion signal, a synsensory signal, or a synsensory-integrated signal, etc. Wherein, the synsensory-sensing fusion signal is used for communication, which can be understood as the signal carrying the communication data or communication reference signal sequence that needs to be transmitted between communication devices. Wherein the synsensory-sensing fusion signal is used for sensing, which can be understood as the synsensory-sensing fusion signal being used to sense (or detect) a target.

[0103] 6) The target can be any tangible object in the environment capable of reflecting electromagnetic waves. In this application, the characteristics of the target can be deduced through sensing signals. For example, mountains, forests, roads, or buildings, and can also include mobile objects such as vehicles, drones, pedestrians, automated equipment, and terminal devices. Optionally, the target can also be referred to as a sensed target, a detected target, a sensed object, a sensed device, a sensing target, a detection target, a sensed object, or a detection object, etc., and the embodiments of this application do not limit this.

[0104] For electromagnetic sensing, a target can generally be modeled as at least one scattering point (or scattering center, scatterer, etc.), and the process of a target reflecting (or scattering, or diffracting, or scattering, etc.) electromagnetic waves can be equivalent to the process of at least one scattering point reflecting (or scattering, or diffracting, or scattering, etc.). For example, for a point-like target, the target can be modeled as a single scattering point. For example, for an extended target, the target can be modeled as multiple scattering points. Accordingly, the target in this application can be understood as a single scattering point, or it can be understood as multiple scattering points. In the following text, unless otherwise specified, the target can be understood as a single scattering point.

[0105] II. Perception Mode:

[0106] In terms of sensing, depending on the sender and receiver of the sensing signal, the sensing mode can be divided into two modes: single-station sensing and dual-station sensing.

[0107] In single-site sensing mode, the device sending sensing signal A and the device receiving sensing signal B are the same device; or, the transmitter sending sensing signal A and the receiver receiving sensing signal B are located in the same device. For example... Figure 1 As shown in (1) or (2) in the diagram, both the device that transmits sensing signal A and the device that receives sensing signal B are device 1. Optionally, the single-station sensing mode can be called self-transmitting and self-receiving mode, single-base sensing mode, or mono-static sensing mode, etc. Figure 1 The target of China and Israel is vehicles, for example.

[0108] For example, device 1 can be a network device, such as Figure 1 (1) in the text; or, device 1 can also be a terminal device, such as Figure 1 As shown in (2) above. For example, device 1 is a network device. In single-site sensing mode, the network device sends sensing signal A and receives sensing signal B to perform environmental sensing. Optionally, device 1 is a network device. Figure 1 The sensing mode shown in (1) can also be called the network device single-site sensing mode. For example, device 1 is a terminal device. In the single-site sensing mode, the terminal device sends sensing signal A and receives sensing signal B to perform environmental sensing. Optionally, device 1 is a terminal device. Figure 1 The sensing mode shown in (2) can also be called the terminal device single-station sensing mode.

[0109] In dual-station sensing mode, the device sending sensing signal A and the device receiving sensing signal B are different devices; or, the transmitter sending sensing signal A and the receiver receiving sensing signal B are located in different devices. For example... Figure 1 As shown in (3), (4), (5), or (6), the device that transmits sensing signal A is device 2, and the device that receives sensing signal B is device 3. Optionally, the dual-station sensing mode can also be called A-transmit B-receive mode, self-transmitting and other-receiving mode, dual-base sensing mode, or bi-static sensing mode, etc.

[0110] For example, device 2 can be a network device, and device 3 can be a terminal device (e.g., referred to as a network device-terminal device dual-site sensing mode), such as... Figure 1 As shown in (3); or device 2 can be a terminal device and device 3 can be a network device (such as denoted as terminal device-network device dual-site sensing mode), such as Figure 1 As shown in (4); or, both device 2 and device 3 can be different network devices (such as denoted as network device A-network device B dual-site sensing mode), such as Figure 1As shown in (5); or, both device 2 and device 3 can be terminal devices (such as denoted as terminal device A-terminal device B dual-station sensing mode), such as Figure 1 As shown in (6) above. For example, device 2 is a network device and device 3 is a terminal device. In the dual-site sensing mode, the network device sends sensing signal A, and the terminal device receives the sensing signal B to perform environmental sensing. For another example, device 2 is a terminal device and device 3 is a network device. In the dual-site sensing mode, the terminal device sends sensing signal A, and the network device receives the sensing signal B to perform environmental sensing. For another example, device 2 is network device 1 and device 3 is network device 2. In the dual-site sensing mode, network device 1 sends sensing signal A, and network device 2 receives sensing signal B to perform environmental sensing. For another example, device 2 is terminal device 1 and device 3 is terminal device 2. In the dual-site sensing mode, terminal device 1 sends sensing signal A, and terminal device 2 receives sensing signal B to perform environmental sensing.

[0111] The sensing signal B includes the echo signal of sensing signal A reflected by the target and / or the signal that is not reflected by the target (such as sensing signal A and / or the echo signal reflected by other tangible objects besides the target).

[0112] III. Terminal Devices:

[0113] A terminal device can be, for example, a terminal equipment, or a component of a terminal equipment, such as a communication module, circuits or chips responsible for communication functions (e.g., modem chips (also known as baseband chips), or system-on-chip (SoC) chips or system-in-package (SIP) chips containing modem cores, chip systems, or processors, etc.) or other functional modules that can be used in a terminal equipment. This chip (or chip system) or other functional module can implement the functions of the terminal equipment. For example, if the chip (or chip system) or other functional module is located in the terminal equipment, it can also be a logic module or software that can implement all or part of the functions of the terminal equipment.

[0114] Among them, terminal equipment is a device with wireless transceiver capabilities that can be deployed on land, including indoor or outdoor, mobile devices, handheld devices (such as mobile phones), wearable devices, or vehicle-mounted devices; or it can be deployed on water (such as ships); or it can be deployed in the air (such as airplanes, balloons, and satellites); or it can be a wireless device (such as a communication module, modem, or chip system) built into the above-mentioned devices.

[0115] The terminal devices are used to connect people, things, and machines, and can be widely used in various scenarios, including but not limited to the following: sensing scenarios, cellular communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) communication, machine-to-machine / machine-type (M2M / MTC) communication, Internet of Things (IoT), virtual reality (VR), augmented reality (AR), industrial control, self-driving, remote medical care, smart grid, smart furniture, smart office, smart wearables, smart transportation, smart city, drones, robots, indoor commercial scenarios (such as mobile phone screen mirroring, file sharing, and mobile phone to VR glasses video transmission), satellite communication, and other scenarios. When the terminal equipment is applied to V2X, it can also be called a V2X device, such as a smart car, digital car, unmanned car, driverless car, pilotless car, or automobile, self-driving car, or autonomous car, pure electric vehicle (EV), hybrid electric vehicle (HEV), range-extended electric vehicle (REEV), plug-in hybrid electric vehicle (PHEV), new energy vehicle, or roadside unit (RSU). The terminal equipment can also be a device used in D2D communication, such as an electricity meter or water meter.

[0116] Furthermore, in this embodiment, the terminal device can also be a terminal device in an IoT system. IoT is an important component of the future development of information technology. Its main technical feature is to connect objects to the network through communication technology, thereby realizing an intelligent network of human-machine interconnection and object-to-object interconnection.

[0117] The various terminal devices described above, if located in a vehicle (e.g., placed inside or installed inside a vehicle), can all be considered in-vehicle terminal devices, also known as on-board units (OBUs). The terminal device of this application can also be an in-vehicle module, in-vehicle component, in-vehicle chip, or in-vehicle unit built into a vehicle as one or more components or units. The vehicle can implement the methods of this application through the built-in in-vehicle module, in-vehicle component, in-vehicle chip, or in-vehicle unit.

[0118] The terminal equipment may sometimes be referred to as user equipment (UE), terminal, access station, UE station, remote station, wireless communication equipment, or user device, etc.

[0119] Optionally, the terms "terminal device" and "terminal equipment" may be used interchangeably.

[0120] IV. Network Equipment:

[0121] Network equipment, including access network equipment and / or core network equipment.

[0122] 1) Core network equipment refers to the equipment in the core network that provides service support to terminals. For example, in the context of a fifth-generation (5G) core network, an evolved 5G core network, or the core network of a future communication system (or sensing system), some examples of core network equipment include: access and mobility management function (AMF) entities, session management function (SMF) entities, user plane function (UPF) entities, policy control function (PCF) entities, location management function (LMF) entities, etc., which will not be listed here. These core network devices can operate independently or be combined to implement certain control functions; for example, AMF, SMF, and PCF can be combined into a single core network device.

[0123] Optionally, the core network equipment may also include a sensing function (SF) entity (or sensing entity). The sensing function entity can be used to sense targets, such as determining the target's location or reconstructing the target's environment, and is not limited thereto. This application does not limit the deployment of the sensing function entity. For example, the sensing function entity can be deployed in the core network or in the access network, without limitation. For example, the sensing function entity can also be a sensing server, a network management platform, or a network management device, etc. It should be understood that in future communication systems (or sensing systems), the functional entity used for sensing targets may still be called a sensing function entity, or it may have other names; this application does not limit this.

[0124] It should be noted that in this application, an entity can also be referred to as a network element or a functional entity. For example, a sensing entity can also be referred to as a sensing network element, a sensing functional entity, or a sensing functional network element.

[0125] 2) Access network equipment is a network-side device with wireless transceiver capabilities. For example, a device that provides wireless communication capabilities to terminal devices in a radio access network (RAN) is called an RAN device or RAN node.

[0126] As an example, the access network equipment includes, but is not limited to, base stations (base transceiver stations, BTS, Node B, evolved Node B (eNodeB) / eNB, or next-generation Node B (gNodeB) / gNB), transmission reception points (TRPs), base stations evolved under the 3rd generation partnership project (3GPP), access nodes in Wi-Fi systems, wireless relay nodes, wireless backhaul nodes, etc. The base station can be a macro base station, micro base station, pico base station, small cell, relay station, etc. Multiple base stations can support networks using the same access technology or networks using different access technologies. A base station can contain one or more co-located or non-co-located transmission and reception points. As another example, the access network equipment can also be a radio controller, central unit (CU), and / or distributed unit (DU) in a cloud radio access network (CRAN) scenario. Optionally, a centralized unit can also be called a control unit. As another example, the access network device can also be a server, etc. For instance, the access network device in V2X technology can be a roadside unit (RSU). The following description uses a base station as an example to illustrate the access network device. A base station can communicate with a terminal device, or it can communicate with a terminal device through a relay station. A terminal device can communicate with multiple base stations using different access technologies.

[0127] Optionally, in the CU-DU architecture, the access network equipment may include one or more logical units (or logical network elements) such as CU, DU, or radio unit (RU). This application does not limit the number of CU, DU, and RU. CU and DU can be configured separately or included in the same network element, such as in a baseband unit (BBU). RU may be included in radio equipment or radio units, such as in a remote radio unit (RRU), active antenna unit (AAU), or remote radiohead (RRH). For example, the CU can perform the functions of the radio resource control (RRC) protocol and packet data convergence protocol (PDCP) of the base station, and can also perform the functions of the service data adaptation protocol (SDAP). For example, the DU can perform the functions of the radio link control layer and medium access control (MAC) layer of the base station, and can also perform some or all of the physical layer functions. For a detailed description of each of the above protocol layers, please refer to the relevant technical specifications of the 3rd Generation Partnership Project (3GPP).

[0128] Optionally, the CU may include a CU-control plane (CP) and / or a CU-user plane (UP). For example, the CU-CP is a logical node carrying the RRC layer and the PDCP-control plane (PDCP-C) layer, and can be used to implement the control plane functions of the CU. For instance, the CU-CP can interact with network elements in the core network used to implement control plane functions. These network elements in the core network can be, for example, sensing network elements, AMFs, etc., and are not limited. For example, the CU-UP is a logical node carrying the SDAP layer and the PDCP-user plane (PDCP-U) layer, and can be used to implement the user plane functions of the CU. For example, the CU-UP can interact with network elements in the core network used to implement user plane functions. These network elements in the core network can be, for example, UPFs, etc., and are not limited.

[0129] In different systems, CU (or CU-CP and / or CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called an open-CU (open-CU, O-CU), DU can also be called an open-DU (open-DU, O-DU), CU-CP can also be called an open-CU-CP (open-CU-CP, O-CU-CP), CU-UP can also be called an open-CU-UP (open-CU-UP, O-CU-UP), and RU can also be called an open-RU (open-RU, O-RU). For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software modules and hardware modules.

[0130] Optionally, in various embodiments of this application, if the access network device is a distributed architecture, for example, the access network device includes CU and DU, or includes CU-CP, CU-UP and DU, then the access network device sends information to the UE, specifically the DU included in the access network device sends information to the UE; the access network device receives information from the UE, specifically the DU included in the access network device receives information from the UE; the access network device sends information to the core network device, specifically the CU (or CU-CP, or CU-UP included in the access network device) sends information to the core network device; the access network device receives information from the core network device, which may include the CU (or CU-CP, or CU-UP included in the access network device receiving information from the core network device.

[0131] In this application embodiment, the device for implementing the network device function can be a network device itself, or a device capable of supporting the network device in implementing that function, such as a chip system, which can be installed in the network device. In the technical solutions provided in this application embodiment, the example of a network device being used to implement the network device function is used to describe the technical solutions provided in this application embodiment.

[0132] V. In the embodiments of this application, "multiple" can refer to two or more. Therefore, in the embodiments of this application, "multiple" can also be understood as "at least two". "At least one" can be understood as one or more, such as one, two or more. For example, "including at least one" means including one, two or more. For example, including at least one of A, B and C, then it can include A, B, C, A and B, A and C, B and C, or A, B and C. "And / or" describes the relationship between related objects. Specifically, there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / ", unless otherwise specified, generally indicates that the related objects before and after are in an "or" relationship.

[0133] In the embodiments of this application, the terms "system" and "network" can be used interchangeably, as can "according to" and "based on". "Carrying" can be replaced with "including".

[0134] The ordinal numbers such as "first" and "second" mentioned in the embodiments of this application are generally used to distinguish different objects, and are not used to limit the order, timing, priority, or importance of multiple objects. For example, the first information and the second information involved in the embodiments of this application are used to distinguish different information, and do not limit the order, timing, priority, or importance of these two pieces of information.

[0135] The terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0136] In this application, "predefined" may include predefined terms, such as protocol definitions. "Predefined" can be implemented by pre-storing corresponding codes, tables, or other means of indicating relevant information in the device (e.g., including various network elements), and this application does not limit the specific implementation method.

[0137] The term "storage" or "preservation" in this application can refer to storage in one or more memory devices. These memory devices can be separately configured or integrated into an encoder, decoder, processor, or communication device. Alternatively, some memory devices can be separately configured, while others can be integrated into the decoder, processor, or communication device. The type of memory can be any form of storage medium, and this is not limited.

[0138] In the schematic diagrams of the accompanying drawings of this application, the dashed arrows or boxes indicate optional steps or optional modules.

[0139] In this application, "instruction" can include direct instruction, indirect instruction, explicit instruction, and implicit instruction. When describing a certain instruction information for the purpose of instructing A, it can be understood that the instruction information carries A, directly instructs A, or indirectly instructs A.

[0140] In this application, the information indicated by the instruction information is called the information to be instructed. In specific implementations, there are many ways to indicate the information to be instructed, such as, but not limited to, directly indicating the information to be instructed, such as the information to be instructed itself or its index. It can also indirectly indicate the information to be instructed by indicating other information, where there is a relationship between the other information and the information to be instructed. It can also indicate only a part of the information to be instructed, while the other parts are known or pre-agreed upon. For example, the instruction of specific information can be achieved by using a pre-agreed (e.g., protocol-defined) arrangement of various pieces of information, thereby reducing instruction overhead to some extent. Furthermore, the information to be instructed can be sent as a whole or divided into multiple sub-information pieces, and the sending period and / or timing of these sub-information pieces can be the same or different.

[0141] In this application, "send" and "receive" indicate the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX, which can include direct transmission via the air interface or indirect transmission via the air interface from other units or modules. "Receive information from YY" can be understood as the source of the information being YY, which can include direct reception from YY via the air interface or indirect reception from YY via the air interface from other units or modules. "Send" can also be understood as the "output" of a chip interface, and "receive" can also be understood as the "input" of a chip interface. In other words, sending and receiving can occur between devices, such as between network devices and terminal devices, or within a device, such as between components, modules, chips, software modules, or hardware modules within the device via buses, traces, or interfaces.

[0142] In this application, the words "exemplarily," "for example," "e.g.," are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as an "example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the word "example" is intended to present concepts in a concrete manner. In the embodiments of this application, "of," "corresponding, relevant," and "corresponding" may sometimes be used interchangeably, and it should be noted that their intended meanings are consistent unless their distinction is emphasized.

[0143] This application will present embodiments relating to a system comprising multiple devices, components, modules, etc. It should be understood that the system may include other unmentioned devices, components, modules, etc., or may include only some of the devices, components, or modules mentioned in the embodiments. Optionally, the terms "component" and "part" in this application can be used interchangeably.

[0144] The communication method provided in this application can be applied to fourth-generation (4G) communication systems, such as Long Term Evolution (LTE) systems, and also to fifth-generation (5G) communication systems, such as 5G New Radio (NR) systems, or to future communication systems. The method provided in this application can also be applied to Bluetooth systems, Wireless Fidelity (Wi-Fi) systems, Long Range Radio (LoRa) systems, or vehicle-to-everything (V2X) systems. The method provided in this application can also be applied to satellite communication systems, wherein the satellite communication system can be integrated with the aforementioned communication systems. It should be understood that the system in which the communication method provided in this application is applied in the future may still be called a communication system, or it may also be called a sensing system, a communication-sensing integrated system, or a communication-sensing integrated system, etc., and this application does not limit this.

[0145] Figure 2 This is a schematic diagram of a scenario that integrates communication and sensing. Figure 2 It may include at least one access network device. Figure 2 The example is an access network device. For instance, the access network device uses a single-site sensing mode, where the sensing of scatterer 3 and scatterer 5 by the access network device is performed in single-site sensing mode.

[0146] Optionally, Figure 2 It may also include at least one UE, Figure 2The example uses multiple UEs. For instance, UE1 and the access network equipment adopt a dual-site sensing mode, where UE1 is the transmitter of sensing signals and the access network equipment is the receiver of sensing signals; UE3 and the access network equipment can also adopt a dual-site sensing mode, where the access network equipment is the transmitter of sensing signals and UE3 is the receiver of sensing signals. Alternatively, the UE can also sample in a single-site sensing mode. Figure 2 Not shown in the image.

[0147] exist Figure 2 In this process, the access network device and UE2 communicate and transmit communication signals. Additionally, the access network device can send communication signals to UE4, and it can also send sensing signals or fusion signals. UE4 can receive these communication signals. If the access network device sends a fusion signal, UE4 can also receive it. If the access network device uses a single-site sensing mode, it can also receive the sensing signal or the fusion signal.

[0148] Figure 2 Taking UE3 as a vehicle and scatterer 3 as a human body as an example, there are no restrictions on the type of other UEs and scatterers.

[0149] For access network equipment, core network equipment, and UE, please refer to the terminology explanation; further details will not be provided here.

[0150] The network architecture and application scenarios described in this application are intended to more clearly illustrate the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0151] Communication sensing technology is one of the key technologies in next-generation wireless communication networks. Improving sensing performance is currently a research hotspot. Therefore, this application provides a communication method and apparatus to improve sensing performance. This communication method and apparatus can also be called a sensing method and apparatus, or an integrated communication and sensing method and apparatus, or an integrated sensing method and apparatus. The method and apparatus described in this application are based on the same technical concept. Since the principles by which the methods and apparatus solve problems are similar, the implementations of the apparatus and method can be referred to each other, and repeated details will not be elaborated further.

[0152] This application's method embodiments relate to an access network device and a terminal device. The access network device is a sensing transmitter, used to transmit sensing signals. The terminal device is a sensing receiver, used to receive sensing signals. In other words, this application's method embodiments use... Figure 1The perception scenario shown in (3) is described using an example. Optionally, the perception signal received by the terminal device may include the echo signal of the perception signal sent by the access network device reflected by the first perception target, and / or, the signal of the perception signal sent by the access network device that has not been reflected by the first perception target (such as the perception signal sent by the access network device, and / or, the echo signal reflected by other tangible objects besides the first perception target). For example, the perception signal received by the terminal device may include the echo signal of the perception signal sent by the access network device and / or the perception signal sent by the access network device. For distinction, in the method embodiment of this application, the perception signal sent by the access network device is denoted as perception signal A, and the perception signal received by the terminal device is denoted as perception signal B. That is, the access network device sends perception signal A, and the terminal device receives perception signal B.

[0153] The access network device is, for example, an access network equipment, or a component of an access network equipment, such as a communication module, circuit or chip responsible for communication functions (e.g., a modem chip, also known as a baseband chip, or a SoC chip or SIP chip containing a modem core, a chip system or processor, etc.) or other functional module that can be applied in the access network equipment. This chip system or functional module can realize the functions of the access network equipment. This chip system or functional module, for example, is located in the access network equipment, and can also be a logic module or software that can realize all or part of the functions of the access network equipment. Optionally, the access network equipment can be a non-ORAN architecture or an ORAN architecture; or, the access network equipment can be a CU, DU, or RU under an ORAN architecture. The access network equipment is, for example, located on the ground, or the access network equipment is, for example, a satellite or an airborne vehicle, or located on a satellite or an airborne vehicle, or on a non-ground device.

[0154] The terminal device is, for example, a terminal equipment, or a component of a terminal equipment, such as a communication module, circuit or chip responsible for communication functions (e.g., a modem chip, also known as a baseband chip, or a SoC chip or SIP chip containing a modem core, a chip system or processor, etc.) or other functional module that can be applied in the terminal equipment. This chip system or functional module can realize the functions of the terminal equipment. For example, if the chip system or functional module is located in the terminal equipment, it can also be a logic module or software that can realize all or part of the functions of the terminal equipment.

[0155] Additionally, please refer to the aforementioned terminology explanations for the terms "sensing target," "sensing signal," "access network equipment," and "terminal equipment," which will not be repeated here.

[0156] In the embodiments of the method in this application, a parameter may involve two subscripts, such as parameter X. i,jThe two subscripts involved are i and j. Different values ​​of i can represent different dimensions. For example, a value of i of 1 can represent the first dimension; a value of i of 2 can represent the second dimension. Different values ​​of j can represent different levels of oversampling. For example, a value of j of 1 can represent first-level oversampling (or first-time oversampling, or single-time oversampling); a value of j of 2 can represent second-level oversampling (or second-time oversampling, or double-time oversampling).

[0157] Here, the first dimension and the second dimension are two different dimensions. For example, the first dimension can be a horizontal dimension, and the second dimension can be a vertical dimension; or, the first dimension can be a vertical dimension, and the second dimension can be a horizontal dimension. As another example, the first and second dimensions can also be two different dimensions parallel to the antenna panel, which may or may not be parallel to the horizontal plane.

[0158] The following description, in conjunction with the accompanying drawings, details a communication method provided by an embodiment of this application. The various embodiments of this application can be applied to... Figure 2 The network architecture shown is not restricted.

[0159] Figure 3 This is a flowchart illustrating a communication method provided in an embodiment of this application. Figure 3 As shown, the method includes the following.

[0160] S301: The access network device sends second information to the terminal device; correspondingly, the terminal device receives the second information from the access network device.

[0161] The second information may include a first oversampling factor and / or a second oversampling factor. That is, the second information may include the first oversampling factor, or include the second oversampling factor, or include both the first and second oversampling factors. Optionally, the oversampling factor may also be referred to as an oversampling factor, oversampling number, etc., and this application does not limit the naming of the oversampling factor.

[0162] The first oversampling factor can be used for sensing and communication. The first oversampling factor can be a positive integer, such as 1, 2, 3, or 4, etc. This application does not limit the value of the first oversampling factor.

[0163] The second oversampling factor can be used for sensing. Optionally, the second oversampling factor can also be used for communication. The second oversampling factor can be a positive integer, such as 2, 3, 4, 5, 6, or 7, etc. This application does not limit the value of the second oversampling factor.

[0164] In this application, the first oversampling factor and the second oversampling factor can be understood as oversampling factors in a first dimension. For example, a signal receiving end (such as a terminal device) can oversample the received sensing signal (and / or communication signal) in the first dimension according to the first oversampling factor and the second oversampling factor. In other words, the second information can be used to configure the oversampling factor in the first dimension. For example, the second information can be used to configure an oversampling factor common to sensing and communication in the first dimension.

[0165] Understandably, the first and second oversampling factors can be configured by the network-side device (such as an access network device or a core network element), or they can be predefined, pre-agreed upon, or default, etc., and this application does not limit them in this regard. Therefore, S301 is an optional step. Figure 3 The middle part is indicated by a dashed line.

[0166] The aforementioned second information includes a first oversampling factor and / or a second oversampling factor. In one example, the second information may include the first oversampling factor, and the second oversampling factor may be predefined, pre-agreed, or a default. In another example, the second information may include the second oversampling factor, and the first oversampling factor may be predefined, pre-agreed, or a default.

[0167] In an optional implementation, the second information may further include a third oversampling factor and / or a fourth oversampling factor. That is, the second information may further include a third oversampling factor, or may further include a fourth oversampling factor, or may further include both a third and a fourth oversampling factor.

[0168] The third oversampling factor can be used for sensing and communication. The third oversampling factor can be a positive integer, such as 1, 2, 3, or 4, etc. This application does not limit the value of the third oversampling factor.

[0169] The fourth oversampling factor can be used for sensing. Optionally, the fourth oversampling factor can also be used for communication. The fourth oversampling factor can be a positive integer, such as 2, 3, 4, 5, 6, or 7, etc. This application does not limit the value of the fourth oversampling factor.

[0170] In this application, the third oversampling factor and the fourth oversampling factor can be understood as oversampling factors in the second dimension. For example, a signal receiver (such as a terminal device) can oversample the received sensing signal (and / or communication signal) in the second dimension according to the third and fourth oversampling factors. In other words, this second information can also be used to configure the oversampling factor in the second dimension. For example, the second information can also be used to configure an oversampling factor common to sensing and communication in the second dimension.

[0171] It is understood that the third and fourth oversampling factors can be configured by network-side devices (such as access network devices or core network elements), or they can be predefined, pre-agreed, or default, etc. This application does not limit them.

[0172] The aforementioned second information may also include a third oversampling factor and / or a fourth oversampling factor. In one example, the second information includes a third oversampling factor, and the fourth oversampling factor may be predefined, pre-agreed, or a default. In another example, the second information includes a fourth oversampling factor, and the third oversampling factor may be predefined, pre-agreed, or a default.

[0173] S302: The access network device sends sensing signal A.

[0174] In this application, the access network device can transmit a sensing signal A. The description of sensing signal A is provided above and will not be repeated here. Optionally, sensing signal A can also be replaced with a communication sensing fusion signal. Optionally, the access network device can also transmit a communication signal. For example, the access network device can also transmit a communication signal to a terminal device. Furthermore, this application does not limit the implementation method of the access network device transmitting sensing signal A.

[0175] S303: The terminal device receives sensing signal B.

[0176] In this application, the terminal device can receive sensing signal B. Please refer to the description of sensing signal B above, which will not be repeated here. Figure 3 The example shown illustrates how a sensing signal B is generated by the reflection (or scattering, diffraction, or diffusion, etc.) of a sensing signal A sent by an access network device through a first sensing target. Optionally, this sensing signal B can also be replaced by a communication sensing fusion signal. Optionally, the terminal device can also receive communication signals. For example, the terminal device can receive communication signals from the access network device. Furthermore, this application does not limit the implementation method of the terminal device receiving the sensing signal B.

[0177] S304: The terminal device sends first information. For example, the terminal device sends first information to the access network device.

[0178] Accordingly, the access network device receives the first information. For example, the access network device receives the first information from the terminal device.

[0179] For example, the terminal device can send first information to the access network device based on the sensing signal B.

[0180] For example, after receiving the sensing signal B, the terminal device can perform matched filtering on the sensing signal B to obtain a filtered signal; perform inverse discrete fourier transform (IDFT) on the filtered signal to obtain the power spectrum; perform constant false alarm rate (CFAR) detection on the power spectrum to obtain angle information, and send first information to the access network device, which can be used to indicate the angle information. It is understood that this application does not limit the implementation method of the terminal device obtaining angle information based on the sensing signal B.

[0181] In this application, the first information is related to a first oversampling factor, and this first information can be used to indicate a first angle of the first perceived target in a first dimension. Alternatively, the first information is related to a first oversampling factor and a second oversampling factor, and this first information can be used to indicate a second angle of the first perceived target in a first dimension. Wherein, the angular resolution of the first angle is lower than (or less than) the angular resolution of the second angle, and / or the minimum spacing between adjacent angles of the first angle is greater than the minimum spacing between adjacent angles of the second angle. Figure 3 The example shown is that the angular resolution of the first angle is lower than that of the second angle.

[0182] Optionally, the angular resolution of the first angle being lower than that of the second angle can be replaced with: the angular resolution of the second angle being higher than (or greater than) that of the first angle. Optionally, the minimum spacing between adjacent angles of the first angle being greater than that of adjacent angles of the second angle can be replaced with: the minimum spacing between adjacent angles of the second angle being less than that of adjacent angles of the first angle. Optionally, the minimum spacing between adjacent angles of the first angle can be understood as: the minimum resolvable angle of the first angle. Optionally, the minimum spacing between adjacent angles of the second angle can be understood as: the minimum resolvable angle of the second angle. Generally, the smaller the minimum resolvable angle, the higher the angular resolution. Therefore, the angular resolution of the first angle being lower than that of the second angle, and the minimum spacing between adjacent angles of the first angle being greater than that of adjacent angles of the second angle, can also be interchanged.

[0183] In other words, the terminal device can feed back coarse-grained angular information of the first perceived target in the first dimension to the access network device, i.e., the first angle, denoted as Method 1; or, the terminal device can also feed back fine-grained angular information of the first perceived target in the first dimension to the access network device, i.e., the second angle, denoted as Method 2. Method 1 and Method 2 are described below.

[0184] Method 1: The first information is related to the first oversampling factor. The first information can be used to indicate the first angle of the first perceived target in the first dimension. For example, if the first dimension is the horizontal dimension, the first angle of the first perceived target in the first dimension can be understood as: the first horizontal angle of the first perceived target. As another example, if the first dimension is the vertical dimension, the first angle of the first perceived target in the first dimension can be understood as: the first vertical angle of the first perceived target.

[0185] For example, please refer to the horizontal and vertical angles of the first perceived target. Figure 4 .like Figure 4 As shown, the horizontal angle can be the angle between the first straight line and the X-axis. The vertical angle can be the angle between the second straight line and the first straight line. The first straight line is the projection of the second straight line onto the XY plane containing the normal to the first antenna panel. The second straight line is the straight line between the device containing the first antenna panel (such as a terminal device or access network device) and the target (such as the first sensing target).

[0186] In this application, the first antenna panel can be the antenna panel of an access network device, or the first antenna panel can be the antenna panel of a terminal device.

[0187] Optionally, the first information is related to the first oversampling factor, which can be understood as: the first information is determined by the first oversampling factor; or as: the first angle indicated by the first information is related to the first oversampling factor; or as: the first angle indicated by the first information is determined by the first oversampling factor.

[0188] In one optional implementation, the first information may include a first value that can be used to indicate a first angle, the first value being related to a first oversampling factor and the number of ports on the first antenna panel in a first dimension. Optionally, the first value being related to the first oversampling factor and the number of ports on the first antenna panel in a first dimension can be understood as: the first value is determined by the first oversampling factor and the number of ports on the first antenna panel in a first dimension. Exemplarily, the first value may satisfy: s 1,1 ∈{0,1,…,N1O 1,1 -1}. Where, s 1,1 The first value is ∈, which is the membership symbol, and O is the first value. 1,1 N1 is the first oversampling factor, and N1 is the number of ports of the first antenna panel in the first dimension (or the number of antennas of the first antenna panel in the first dimension).

[0189] In the above embodiments, the terminal device can indicate a first angle through a first value; correspondingly, the access network device can determine the first angle based on the first value. As an example, the first angle can be determined by the first value, a first oversampling factor, and the number of ports on the first antenna panel in the first dimension. For example, after receiving the first information, the access network device can determine the first angle based on the first value, the first oversampling factor, and the number of ports on the first antenna panel in the first dimension. Exemplarily, the first angle can satisfy: Where π is the mathematical constant pi, and s 1,1 As the first value, O 1,1 N1 is the first oversampling factor, and N1 is the number of ports on the first antenna panel in the first dimension (or the number of antennas on the first antenna panel in the first dimension).

[0190] In one optional implementation, the first angle can be the angle obtained by oversampling the sensed signal B in a first dimension according to a first oversampling factor. For example, the terminal device receives the sensed signal B, oversamples the sensed signal B in a first dimension according to the first oversampling factor to obtain oversampled information, and determines the first angle based on the oversampled information. For example, after receiving the sensed signal B, the terminal device can perform matched filtering on the sensed signal B to obtain a filtered signal; and perform N1O on the filtered signal. 1,1 The IDFT can obtain the power spectrum #1; CFAR detection of the power spectrum #1 can obtain the first angle, such as... Figure 5 As shown in (1) above. For example, the terminal device can perform N1O on the filtered signal in the first dimension. 1,1 The IDFT yielded the power spectrum #1. Among them, N1 and O... 1,1 Please refer to the previous text.

[0191] For example, suppose the access network device is configured with N1 transmit antennas in the first dimension (such as the horizontal dimension), and the terminal device is configured with a single antenna. The discrete baseband signal transmitted by the m-th transmit antenna among the N1 transmit antennas in symbol n is denoted as x. m (n), then the signal transmitted by the access network device at symbol n can be x(n) is scattered by the target (such as the first sensing target) and received by the receiving antenna of the terminal device. Assume the target's scattering cross-section is α, the propagation delay of the scattering path is τ, and the departure angle and / or arrival angle is θ. T The antenna spacing between adjacent transmitting antennas is d. T If the interference and noise signals are ∈(n), then the signal received by the terminal device (including the sensing signal B) is denoted as y(n), and y(n) can satisfy the following formula (1).

[0192]

[0193] Where j is the imaginary unit (or complex unit), e is the natural constant, π is pi, and f c Let be the carrier frequency, c be the speed of light, and cos be the cosine function.

[0194] The m-th sensing signal in y(n) can be denoted as y m (n), the y m (n) can satisfy

[0195] Furthermore, the terminal device can determine the first angle through the following steps A1 to A3.

[0196] Step A1: The terminal device y(n) performs matched filtering to obtain the filtered signal, denoted as R(n). This R(n) satisfies: in, Indicates x m (n) performs conjugate operations.

[0197] Step A2: The terminal device performs N1O on R(n). 1,1 The power spectrum #1 is obtained by performing the IDFT, denoted as z1(n).

[0198] Step A3: The terminal device can obtain the first angle by performing CFAR detection on z1(n).

[0199] Understandably, this application does not limit the implementation method of the terminal device determining the first angle.

[0200] In this first method, the terminal device can feed back the angle information of the first sensing target in one dimension to the access network device. In another optional implementation, the access network device can also feed back the angle information of the first sensing target in two dimensions, offering flexibility and adaptability to various communication scenarios. As an example, the first information can also be related to a third oversampling factor, and the first information can also be used to indicate the third angle of the first sensing target in the second dimension. Here, the first dimension and the second dimension are two different dimensions; please refer to the preceding text for details, which will not be repeated here. For example, if the second dimension is a vertical dimension, the third angle of the first sensing target in the second dimension can be understood as: the third vertical angle of the first sensing target. As another example, if the second dimension is a horizontal dimension, the third angle of the first sensing target in the second dimension can be understood as: the third vertical angle of the first sensing target. The horizontal angle and vertical angle can be referred to... Figure 4 .

[0201] Optionally, the first information is also related to the third oversampling factor, which can be understood as: the first information is also determined by the third oversampling factor; or as: the third angle indicated by the first information is related to the third oversampling factor; or as: the third angle indicated by the first information is determined by the third oversampling factor.

[0202] In an optional implementation, the first information may further include a second value, which can be used to indicate a third angle, the second value being related to a third oversampling factor and the number of ports on the first antenna panel in the second dimension. Optionally, the second value being related to the third oversampling factor and the number of ports on the first antenna panel in the second dimension can be understood as: the second value is determined by the third oversampling factor and the number of ports on the first antenna panel in the second dimension. Exemplarily, the second value may satisfy: s 2,1 ∈{0,1,…,N2O 2,1 -1}. Where, s 2,1 The second value is ∈, which is the membership symbol, and O 2,1 N2 is the third oversampling factor, and N2 is the number of ports on the first antenna panel in the second dimension (or the number of antennas on the first antenna panel in the second dimension).

[0203] In the above embodiments, the terminal device can indicate the third angle through the second value; correspondingly, the access network device can determine the third angle based on the second value. As an example, the third angle can be determined by the second value, the third oversampling factor, and the number of ports on the first antenna panel in the second dimension. For example, after receiving the first information, the access network device can determine the third angle based on the second value, the third oversampling factor, and the number of ports on the first antenna panel in the second dimension. Exemplarily, the third angle can satisfy: Where π is the mathematical constant pi, and s 2,1 For the second value, O 2,1 N2 is the third oversampling factor, and N2 is the number of ports on the first antenna panel in the second dimension (or the number of antennas on the first antenna panel in the second dimension).

[0204] In one optional implementation, the third angle can be the angle obtained by oversampling the sensed signal B in the second dimension according to a third oversampling factor. For example, the terminal device receives the sensed signal B, oversamples the sensed signal B in the second dimension according to a third oversampling factor to obtain oversampled information, and determines the third angle based on the oversampled information. For example, after receiving the sensed signal B, the terminal device can perform matched filtering on the sensed signal B to obtain a filtered signal; and perform N2O on the filtered signal. 2,1 The IDFT can obtain the power spectrum #3; CFAR detection of the power spectrum #3 can obtain the third angle, which can be referenced. Figure 5 (1) In this context, for example, the terminal device can perform N2O on the filtered signal in the second dimension.2,1 The IDFT yielded the power spectrum #3. Among them, N2 and O... 2,1 Please refer to the previous text. The process of determining the third angle by the terminal device can be referred to the process of determining the first angle by the terminal device, and will not be repeated here.

[0205] Optionally, in this method one, the first information can be recorded as (first value, second value), such as (s 1,1 s 2,1 The angle indicated by the first piece of information can be recorded as (first angle, third angle), such as... Among them, s 1,1 It can be used to indicate the first angle of the first perceived target in the first dimension, that is, s 1,1 Used to indicate s 2,1 It can be used to indicate the third angle of the first perceived target in the second dimension, that is, s 2,1 Used to indicate

[0206] In an optional implementation, the first and second values ​​can also be used to indicate a precoding matrix indicator (PMI); or, the first and second values ​​can also be used to indicate a data channel; or, the first and second values ​​can also be used to indicate a bandwidth beamgroup corresponding to the communication data. The data channel can be, for example, a PDSCH. In other words, the first information is related to a first oversampling factor and a third oversampling factor, and this first information can also be used to indicate the PMI, or to indicate a data channel, or to indicate a bandwidth beamgroup corresponding to the communication data. That is, the first information is also used to indicate a candidate beamgroup for communication. For example, the first value can be used to indicate a candidate beam in a first dimension. For example, the second value can be used to indicate a candidate beam in a second dimension. Through this implementation, the first and second values ​​can not only indicate angle information used for sensing, but also indicate the PMI used for communication. Compared to using different information to indicate angle information and PMI separately, using one piece of information to indicate angle information and PMI can reduce feedback overhead and improve the utilization of network resources.

[0207] In Method 1, the first information is associated with a sampling factor and can be used to indicate a first angle of the first perceived target in a first dimension. Additionally, when the first information is used to indicate the angle information of the first perceived target in two dimensions, it can also be used to indicate PMI, which can reduce feedback overhead.

[0208] Method Two: The first information is related to the first oversampling factor and the second oversampling factor. This first information can be used to indicate the second angle of the first perceived target in the first dimension. For example, if the first dimension is a horizontal dimension, the second angle of the first perceived target in the first dimension can be understood as: the second horizontal angle of the first perceived target. As another example, if the first dimension is a vertical dimension, the second angle of the first perceived target in the first dimension can be understood as: the second vertical angle of the first perceived target. The horizontal and vertical angles can be referenced... Figure 4 .

[0209] Optionally, the first information is related to the first oversampling factor and the second oversampling factor, which can be understood as: the first information is determined by the first oversampling factor and the second oversampling factor; or as: the second angle indicated by the first information is related to the first oversampling factor and the second oversampling factor; or as: the second angle indicated by the first information is determined by the first oversampling factor and the second oversampling factor.

[0210] In one optional implementation, the first information may include a first value and a third value, which can be used to indicate a second angle. The first value is related to a first oversampling factor and the number of ports on the first antenna panel in a first dimension, and the third value is related to a second oversampling factor. The first value and the first antenna panel are as described above and will not be repeated here. Optionally, the third value being related to the second oversampling factor can be understood as the third value being determined by a third oversampling factor. For example, the third value may satisfy: s 1,2 ∈{0,1,…,O 1,2 -1}. Where, s 1,2 The third value, ∈ represents the membership symbol, O 1,2 This is the second oversampling factor.

[0211] In the above embodiments, the terminal device can indicate the second angle using the first value and the third value; correspondingly, the access network device can determine the second angle based on the first value and the third value. As an example, the second angle can be determined by the first value, the third value, the first oversampling factor, the second oversampling factor, and the number of ports on the first antenna panel in the second dimension. For example, after receiving the first information, the access network device can determine the second angle based on the first value, the third value, the first oversampling factor, the second oversampling factor, and the number of ports on the first antenna panel in the second dimension. Exemplarily, the second angle can satisfy: Where π is the mathematical constant pi, and s 1,1 As the first value, s 1,2 The third value, O 1,1 For the first oversampling factor, O 1,2 The second oversampling factor is N1, and N1 is the number of ports on the first antenna panel in the first dimension.

[0212] In one alternative implementation, the second angle can be an angle obtained by oversampling the sensed signal B in a first dimension according to a first oversampling factor and a second oversampling factor. For example, the terminal device receives the sensed signal B, oversamples the sensed signal B in a first dimension according to a first oversampling factor and a second oversampling factor to obtain oversampled information, and determines the second angle based on the oversampled information.

[0213] As an example, the second angle can be obtained by oversampling third information in the first dimension according to a second oversampling factor, where the third information is obtained by oversampling the sensed signal B in the first dimension according to a first oversampling factor. For example, after receiving the sensed signal B, the terminal device can oversample the sensed signal B in the first dimension according to the first oversampling factor to obtain the third information, and then oversample the third information in the first dimension according to the second oversampling factor to obtain the oversampled information. The second angle is then determined based on this oversampled information. In other words, the terminal device can perform a second oversampling of the sensed signal B in the first dimension according to the first and second oversampling factors to obtain the second angle.

[0214] As another example, the second angle can be obtained by oversampling the sensed signal in the first dimension according to a fifth oversampling factor, where the fifth oversampling factor is the product of the first and second oversampling factors. For example, after receiving the sensed signal B, the terminal device can oversample the sensed signal B in the first dimension according to the fifth oversampling factor to obtain oversampled information, and determine the second angle based on this oversampled information. In other words, the terminal device can also oversample the sensed signal B once in the first dimension according to the first and second oversampling factors to obtain the second angle.

[0215] For example, after receiving the sensing signal B, the terminal device can perform matched filtering on the sensing signal B to obtain a filtered signal; and perform N1O on the filtered signal. 1,1 O 1,2 The IDFT can obtain the power spectrum #2; CFAR detection of the power spectrum #2 can obtain the second angle, such as... Figure 5 As shown in (2) above. For example, the terminal device can perform N1O on the filtered signal in the first dimension. 1,1 O 1,2 The IDFT yielded the power spectrum #1. Among them, N1 and O... 1,1 O 1,2 Please refer to the previous text.

[0216] For example, the terminal device can determine the second angle through the following steps B1 to B3.

[0217] Step B1: The terminal device performs matched filtering on y(n) to obtain the filtered signal, denoted as R(n). Please refer to the previous text for the meanings of y(n) and R(n).

[0218] Step B2: The terminal device performs N1O on R(n). 1,1 O 1,2 The IDFT yields the power spectrum #2, denoted as z2(n).

[0219] Step B3: The terminal device can obtain the second angle by performing CFAR detection on z2(n).

[0220] Understandably, this application does not limit the implementation method of the terminal device determining the second angle.

[0221] In this application, both the first angle and the second angle are angular information of the first perceived target in a first dimension. The angular resolution of the first angle is lower than (or less than) the angular resolution of the second angle, and / or the minimum spacing between adjacent angles of the first angle is greater than the minimum spacing between adjacent angles of the second angle. For example, assuming N1 is 20, O 1,1 4, O 1,2 If the value is 12, then the minimum distance between adjacent angles of the first angle is... The minimum distance between adjacent angles of the second angle is It is evident that the minimum spacing between adjacent angles of the first angle is greater than the minimum spacing between adjacent angles of the second angle. That is, the angular resolution of the first angle is lower than the angular resolution of the second angle. Where N1 and O... 1,1 O 1,2 Please refer to the previous text.

[0222] In this second method, the terminal device can feed back the angle information of the first sensing target in one dimension to the access network device. In another optional implementation, the access network device can also feed back the angle information of the first sensing target in two dimensions, offering flexibility and adaptability to various communication scenarios. As an example, the first information can also be related to a third oversampling factor and a fourth oversampling factor, and the first information can also be used to indicate the fourth angle of the first sensing target in the second dimension. For example, if the second dimension is a vertical dimension, the fourth angle of the first sensing target in the second dimension can be understood as: the fourth vertical angle of the first sensing target. As another example, if the second dimension is a horizontal dimension, the fourth angle of the first sensing target in the second dimension can be understood as: the fourth vertical angle of the first sensing target. The horizontal and vertical angles can be referenced... Figure 4 .

[0223] Optionally, the first information is also related to the third oversampling factor and the fourth oversampling factor, which can be understood as: the first information is also determined by the third oversampling factor and the fourth oversampling factor; or as: the third angle indicated by the first information is related to the third oversampling factor and the fourth oversampling factor; or as: the third angle indicated by the first information is determined by the third oversampling factor and the fourth oversampling factor.

[0224] In an optional implementation, the first information may further include a second value and a fourth value, which are used to indicate a fourth angle. The second value is related to a third oversampling factor and the number of ports on the first antenna panel in the second dimension, and the fourth value is related to a fourth oversampling factor. The first antenna panel is an antenna panel of an access network device or a terminal device. The second value is described above and will not be repeated here. Optionally, the fourth value is related to a fourth oversampling factor, which can be understood as: the fourth value is determined by the fourth oversampling factor. For example, the fourth value may satisfy: s 2,2 ∈{0,1,…,O 2,2 -1}. Where, s 2,2 The fourth value, ∈ represents the membership symbol, O 2,2 This is the fourth oversampling factor.

[0225] In the above embodiments, the terminal device can indicate the fourth angle using the second and fourth values; correspondingly, the access network device can determine the fourth angle based on the second and fourth values. As an example, the fourth angle can be determined by the second value, the fourth value, the third oversampling factor, the fourth oversampling factor, and the number of ports on the first antenna panel in the second dimension. For example, after receiving the first information, the access network device can determine the fourth angle based on the second value, the fourth value, the third oversampling factor, the fourth oversampling factor, and the number of ports on the first antenna panel in the second dimension. Exemplarily, the fourth angle can satisfy: Where π is the mathematical constant pi, and s 2,1 For the second value, s 2,2 The fourth value, O 2,1 For the third oversampling factor, O 2,2 N is the fourth oversampling factor, and N2 is the number of ports on the first antenna panel in the second dimension.

[0226] In one alternative implementation, the fourth angle can be an angle obtained by oversampling the sensed signal B in the second dimension based on the third and fourth oversampling factors. For example, the terminal device receives the sensed signal B, oversamples the sensed signal B in the second dimension based on the third and fourth oversampling factors to obtain oversampled information, and determines the fourth angle based on the oversampled information.

[0227] As an example, the fourth angle can be obtained by oversampling the fourth information in the second dimension according to a fourth oversampling factor, and the fourth information is obtained by oversampling the sensed signal B in the second dimension according to a third oversampling factor. For example, after receiving the sensed signal B, the terminal device can oversample the sensed signal B in the second dimension according to a third oversampling factor to obtain the fourth information, and then oversample the fourth information in the second dimension according to a fourth oversampling factor to obtain the oversampled information, and determine the fourth angle based on the oversampled information. In other words, the terminal device can perform a second oversampling of the sensed signal B in the second dimension according to the third and fourth oversampling factors to obtain the fourth angle.

[0228] As another example, the fourth angle can be obtained by oversampling the sensed signal in the second dimension according to a sixth oversampling factor, where the sixth oversampling factor is the product of the third and fourth oversampling factors. For example, after receiving the sensed signal B, the terminal device can oversample the sensed signal B in the second dimension according to the sixth oversampling factor to obtain the oversampled information, and determine the fourth angle based on this oversampled information. In other words, the terminal device can also obtain the fourth angle by oversampling the sensed signal B once in the second dimension according to the third and fourth oversampling factors.

[0229] For example, after receiving the sensing signal B, the terminal device can perform matched filtering on the sensing signal B to obtain a filtered signal; and perform N2O on the filtered signal. 2,1 O 2,2 The IDFT can obtain the power spectrum #4; CFAR detection of the power spectrum #4 can obtain the fourth angle, which can be referenced. Figure 5 (2) In this context, for example, the terminal device can perform N2O on the filtered signal in the second dimension. 2,1 O 2,2 The IDFT yielded the power spectrum #4. Among them, N2 and O... 2,1 O 2,2 Please refer to the previous text. The process of determining the fourth angle by the terminal device can be referred to the process of determining the second angle by the terminal device, and will not be repeated here.

[0230] In this application, the third angle and the fourth angle are both angular information of the first perceived target in the second dimension. The angular resolution of the third angle is lower than (or less than) the angular resolution of the fourth angle, and / or the minimum spacing between adjacent angles of the third angle is greater than the minimum spacing between adjacent angles of the fourth angle. Optionally, the angular resolution of the third angle being lower than the angular resolution of the fourth angle can be replaced by: the angular resolution of the fourth angle being higher than (or greater than) the angular resolution of the third angle. Optionally, the minimum spacing between adjacent angles of the third angle being greater than the minimum spacing between adjacent angles of the fourth angle can be replaced by: the minimum spacing between adjacent angles of the fourth angle being less than the minimum spacing between adjacent angles of the third angle. Optionally, the minimum spacing between adjacent angles of the third angle can be understood as: the minimum resolvable angle of the third angle. Optionally, the minimum spacing between adjacent angles of the fourth angle can be understood as: the minimum resolvable angle of the fourth angle. Generally, the smaller the minimum resolvable angle, the higher the angular resolution. Therefore, the angular resolution of the third angle being lower than the angular resolution of the fourth angle and the minimum spacing between adjacent angles of the third angle being greater than the minimum spacing between adjacent angles of the fourth angle can also be interchanged.

[0231] For example, suppose N² is 20, O 2,1 4, O 2,2 If the value is 8, then the minimum distance between adjacent angles of the first angle is... The minimum distance between adjacent angles of the second angle is It is evident that the minimum spacing between adjacent angles of the third angle is greater than that of the fourth angle. That is, the angular resolution of the third angle is lower than that of the fourth angle. Wherein, N2, O 2,1 O 2,2 Please refer to the previous text.

[0232] Optionally, in this second method, the first information can be recorded as (first value, third value; second value, fourth value), such as (s 1,1 s 1,2 ;

[0233] s 2,1 s 2,2 The angle indicated by the first piece of information can be recorded as (second angle, fourth angle), such as... Among them, s 1,1 and s 1,2 It can be used to indicate the second angle of the first perceived target in the first dimension, that is, s 1,1 and s 1,2 Used to indicate s 2,1 and s 2,2 It can be used to indicate the fourth angle of the first perceived target in the second dimension, that is, s 2,1 and s 2,2 Used to indicate

[0234] In Method 2, when the first information is related to two oversampling factors, the first information can be used to indicate a second angle with high angular resolution, so that the access network device can obtain a more accurate sensing result by using the second angle, thereby improving the sensing performance.

[0235] For example, the first dimension is the horizontal dimension, and the first oversampling factor is 4 (i.e., O). 1,1 The second oversampling factor is 12 (i.e., O). 1,2 If the value is 12), then the oversampling in the horizontal direction can be referenced. Figure 6 (1) of the above. The second dimension is the vertical dimension, and the third oversampling factor is 4 (i.e., O). 2,1 The fourth oversampling factor is 8 (i.e., O). 2,2 If the value is 8), then for oversampling in the vertical direction, please refer to [reference needed]. Figure 6 (2) Further, assuming the first antenna panel has 4 ports in the horizontal direction (i.e., N1 is 4) and 2 ports in the vertical direction (i.e., N2 is 2), please refer to [reference needed] for oversampling in the horizontal and vertical directions. Figure 6 (3) If the minimum value of the first, second, and third values ​​is 0 (i.e., the index number starts from 0), then the first value is 12, the second value is 4, the third value is 3, and the fourth value is 3. If the terminal device reports using the above method one, the first information can be represented as (12, 4). If the terminal device reports using the above method two, the first information can be represented as (12, 4; 3, 3).

[0236] Understandably, this application does not limit the implementation form of the first information.

[0237] As mentioned earlier, the first antenna panel can be the antenna panel of an access network device, or it can be the antenna panel of a terminal device. When the first antenna panel is the antenna panel of an access network device, the first angle and / or the second angle can be understood as: the angle of departure from the first antenna panel to the first sensing target in the first dimension. Similarly, when the first antenna panel is the antenna panel of an access network device, the third angle and / or the fourth angle can be understood as: the angle of departure from the first antenna panel to the first sensing target in the second dimension. Optionally, the first information can also be used to indicate the angle information of the angle of arrival of the first sensing target to the antenna panel of the terminal device in the first dimension, and / or to indicate the angle information of the angle of arrival of the first sensing target to the antenna panel of the terminal device in the second dimension. For details, please refer to the implementation of the first angle, the second angle, the third angle, and the fourth angle, which will not be repeated here.

[0238] Alternatively, when the first antenna panel is the antenna panel of a terminal device, the first angle and / or the second angle can be understood as: the angle of arrival from the first sensing target to the first antenna panel in the first dimension. Similarly, when the first antenna panel is the antenna panel of a terminal device, the third angle and / or the fourth angle can be understood as: the angle of arrival from the first sensing target to the first antenna panel in the second dimension.

Figure 3 Not shown in the diagram. The perception result may be, for example, the position, velocity, distance, or shape of the first perceived target, and is not limited thereto.

[0240] In the embodiments of this application, the terminal device can feed back the angle information (such as a first angle or a second angle) of the first sensing target in a first dimension to the access network device, so that the access network device can use the angle information of the first sensing target in the first dimension to realize the perception of the first sensing target (such as obtaining the position, distance, etc. of the first sensing target), which is beneficial to improving the perception performance. In addition, when the first information is related to two oversampling factors, the first information can be used to indicate a second angle with high angular resolution, so that the access network device can use the second angle to obtain a higher precision perception result, thereby improving the perception performance.
