Description

Sensing method and communication device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on October 31, 2023, with application number 202311438943.8 and application name “Perception Method and Communication Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of perception communication, and in particular to a perception method and a communication device. Background Art

[0003] In the integration of communication and perception, wireless perception can include three processes: perception capability reporting, perception measurement configuration, and perception measurement reporting. The sensing function (SF) can determine the perception measurement configuration based on the perception capabilities reported by the terminal device and the access network device, and then send it to the terminal device and / or access network device for perception measurement. Alternatively, the access network device can determine the perception measurement configuration based on the perception capabilities reported by the terminal device, and then send it to the terminal device for perception measurement, thereby obtaining the perception measurement results. Different perception modes involve different devices.

[0004] During the wireless sensing process, access network devices configure sensing measurements for connected devices via radio resource control (RRC) reconfiguration messages. However, they are unable to configure sensing for disconnected devices. Therefore, implementing sensing configuration and reporting for disconnected devices has become a pressing issue.

[0005] Summary of the Invention

[0006] The embodiments of the present application provide a perception method and a communication device, which can realize the perception configuration and reporting of terminal devices in a non-connected state.

[0007] To achieve the above objectives, this application adopts the following technical solutions:

[0008] In a first aspect, a perception method is provided, which can be executed by a first access network device, or by a component of the first access network device, such as a processor, chip, or chip system of the first access network device, or can be implemented by a logic module or software that can implement all or part of the first access network device, such as a distributed unit (DU) in the first access network device. The method includes: the first access network device sends a paging message. The paging message is used to page a terminal device belonging to a first perception group. When the paging is completed, the first access network device sends a first perception configuration for performing a perception task.

[0009] Based on this communication method, the first access network device can page the terminal devices in the non-connected state belonging to the first perception group through a paging message, and when the paging is completed, the perception configuration is performed for the terminal devices in the non-connected state that meet the paging conditions. In this way, not only can it be avoided that all terminal devices with perception capabilities respond to the paging after the paging is initiated, the network connection pressure can be reduced, and the perception configuration efficiency can be improved. Furthermore, by performing perception configuration on the terminal devices in the non-connected state, the terminal devices can perform perception measurements in the non-connected state, which can reduce the energy consumption of the terminal devices and further reduce the network connection pressure.

[0010] In a possible design scheme, the first access network device sends a paging message, which may include: the first access network device receives a first message from the access and mobility management network element. The first message is used to request the first access network device to perform perception configuration for the terminal device belonging to the first perception group. The first access network device sends a paging message according to the first message. Thus, the first access network device can trigger the paging of the non-connected terminal device based on the access and mobility management network element, and perform perception configuration on the paged non-connected terminal device to achieve perception configuration and reporting of the non-connected terminal device. In an embodiment of the present application, the access and mobility management network element can be an access and mobility management function (AMF).

[0011] In one possible design, the first message and the paging message include information indicating the first perception group, wherein the information of the first perception group may be an identifier or index of the first perception group, or other information indirectly indicating the first perception group, which is not limited.

[0012] In one possible design scheme, the perception method provided in the embodiment of the present application may further include: before receiving the first message, the first access network device sends a radio resource control (RRC) release message to the first terminal device. The RRC release message includes information indicating the perception group to which the first terminal device belongs, and the perception group to which the first terminal device belongs includes the first perception group. Thus, the first access network device can inform the terminal device of the perception group information of the terminal device when releasing the terminal device to a non-connected state, thereby reducing signaling overhead.

[0013] In one possible design, the first message includes information indicating an area where a sensing task is to be performed; and the first access network device sending the paging message may include: the first access network device determining a paging beam based on the information indicating the area where the sensing task is to be performed, and sending the paging message via the paging beam. Thus, when sending the paging message, the first access network device may configure the paging beam based on the sensing area information, ensuring that the paged terminal device is located within the sensing area, thereby improving the efficiency and flexibility of sensing configuration.

[0014] In one possible design, the area where the sensing task is performed is covered by the paging beam.

[0015] In one possible design, the first message may further include a second perception configuration, which is used to indicate a measurement and / or reporting period for performing the perception task within a preset time. Thus, the first access network device can determine the period for performing the perception task and / or the reporting period for the non-connected terminal device based on the first message sent by the access and mobility management network element. This can reduce the time required by the first access network device to determine the period for performing the perception task and / or the reporting period for the non-connected terminal device, thereby improving perception configuration efficiency.

[0016] In one possible design scheme, the second perception configuration may include at least one of the following: information for indicating a perception task, information for indicating measurements for periodically performing a perception task, information for indicating reporting of measurement results for periodically performing a perception task, information for indicating the time for performing the perception task, or information for indicating an area for performing the perception task.

[0017] In one possible design scheme, the first access network device sends the first perception configuration for performing the perception task, which may include: the first access network device sends the first perception configuration for performing the perception task according to the second perception configuration.

[0018] In one possible design scheme, the first perception configuration may include at least one of the following: information for indicating a perception task, information for indicating measurements for periodically performing a perception task, information for indicating reporting of measurement results for periodically performing a perception task, information for indicating the time for performing the perception task, information for indicating an area for performing the perception task, or information for indicating resources for performing the perception task.

[0019] In a possible design scheme, the first access network device sends a first perception configuration for performing a perception task, which may include: the first access network device receives an RRC recovery request message or an RRC establishment message from the first terminal device. The RRC recovery request message or the RRC establishment message is used to request recovery from a non-connected state to a connected state. The first access network device sends an RRC reconfiguration message or an RRC release message to the first terminal device. The RRC reconfiguration message or the RRC release message includes the first perception configuration. Thus, the first access network device can page the first terminal device back to the connected state to complete the perception configuration of the first terminal device in the non-connected state. After the first terminal device completes the perception configuration, it is released to the non-connected state, so that the terminal device still perceives in the non-connected state, which can reduce the energy consumption of the terminal device.

[0020] In one possible design, the first access network device sending a first perception configuration for performing a perception task may include: the first access network device sending a first broadcast message. The first broadcast message includes the first perception configuration. Thus, the first access network device can send the first perception configuration via the broadcast message, allowing the first terminal device to perform perception configuration and perception measurement while remaining in a disconnected state, thereby reducing energy consumption of the terminal device and reducing network connection pressure.

[0021] In one possible design, the perception method provided in an embodiment of the present application may further include: a first access network device sending a first perception signal for performing a perception task. The first access network device receives a second message from a first terminal device. The second message is used to indicate a first perception measurement result of the perception task performed by the first terminal device based on an echo signal corresponding to the first perception signal. Thus, when performing the perception task, the first access network device may send the perception signal to enable a non-connected terminal device to perform a perception measurement.

[0022] In a possible design scheme, the perception method provided by the embodiment of the present application may further include: the first access network device sends a second broadcast message to the first terminal device. The second broadcast message includes information for indicating whether the first terminal device performs the perception task. For example, in a case where the first access network device does not perform paging according to the perception area information, or in a case where the area covered by the paging beam determined by the first access network device according to the perception area information is larger than the perception area within its coverage area, the first access network device can inform the first terminal device whether it is in the perception area and whether to perform the perception task through the second broadcast message, which can reduce useless measurements and reports by the terminal device.

[0023] In a possible design scheme, the perception method provided by the embodiment of the present application may also include: a second broadcast message from the first access network device to the first terminal device. The second broadcast message includes a first identifier, and the first identifier is used to identify the first terminal device to perform the perception task. Thus, for example, in a case where the first access network device does not perform paging according to the perception area information, and the area covered by the paging beam determined by the first access network device according to the perception area information is larger than the perception area within its coverage area, the first access network device can also indicate whether the non-connected UE is located in the perception area and whether to perform perception measurements by whether to carry the first identifier in the broadcast message, so that the terminal device can reduce useless measurements and reports. For example, the first identifier is used to identify the area where the first access network device currently sends the second broadcast message, and the first identifier is used to identify a more fine-grained area.

[0024] In one possible design solution, the first perception measurement result may include a first identifier. For example, the first access network device may determine in which area the first terminal device obtains the first perception measurement result.

[0025] In one possible design, the perception method provided in an embodiment of the present application may further include: the first access network device sending a third message to the perception network element. The third message includes the first perception measurement result.

The RRC recovery request message or the RRC establishment message is used to request recovery from a non-connected state to a connected state. The first terminal device receives an RRC reconfiguration message from the first access network device. The RRC reconfiguration message includes the first perception configuration.

[0030] In a possible design scheme, the perception method provided in the embodiment of the present application may also include: after receiving the first perception configuration, the first terminal device receives an RRC release message from the first access network device.

[0031] In a possible design scheme, when the first terminal device belongs to the first perception group, the first terminal device receives a first perception configuration for performing a perception task from the first access network device, which may include: when the first terminal device belongs to the first perception group, the first terminal device sends an RRC recovery request message or an RRC establishment message to the first access network device. The RRC recovery request message or the RRC establishment message is used to request recovery from a non-connected state to a connected state. The first terminal device receives an RRC release message from the access network device. The RRC release message includes the first perception configuration.

[0032] In one possible design, when a first terminal device belongs to a first perception group, the first terminal device receiving a first perception configuration for performing a perception task from a first access network device may include: when the first terminal device belongs to the first perception group, the first terminal device receiving a first broadcast message from the first access network device.

[0033] In one possible design, the perception method provided in an embodiment of the present application may further include: when in a non-connected state, the first terminal device receives, according to a first perception configuration, an echo signal corresponding to a first perception signal used to perform a perception task. The first terminal device determines a first perception measurement result based on the echo signal corresponding to the first perception signal. The first terminal device sends the first perception measurement result to the first access network device.

[0034] In one possible design solution, the sensing method provided in the embodiment of the present application may further include: the first terminal device receiving a second broadcast message from the first access network device, wherein the second broadcast message includes information indicating whether the first terminal device performs the sensing task.

[0073] In order to better understand the embodiments of the present application, the following explanations are made before introducing the embodiments of the present application.

[0074] First, in the embodiments of the present application, "used to indicate" can include being used for direct indication and being used for indirect indication. When describing a certain "indication information" as being used to indicate A, it can include the indication information directly indicating A or indirectly indicating A, and does not necessarily mean that the indication information carries A.

[0075] The information indicated by the indication information is called the information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as but not limited to, directly indicating the information to be indicated, such as the information to be indicated itself or the index of the information to be indicated. The information to be indicated can also be indirectly indicated by indicating other information, wherein there is an association between the other information and the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, it is also possible to use the arrangement order of each piece of information agreed in advance (such as specified in the protocol) to achieve the indication of specific information, thereby reducing the indication overhead to a certain extent. At the same time, it is also possible to identify the common parts of each piece of information and indicate them uniformly to reduce the indication overhead caused by indicating the same information separately.

[0076] In addition, the specific indication method can also be various existing indication methods, such as but not limited to the above-mentioned indication methods and various combinations thereof. The specific details of the various indication methods are not limited in this application. As can be seen from the above, for example, when it is necessary to indicate multiple information of the same type, there may be a situation where the indication methods for different information are different. In the specific implementation process, the required indication method can be selected according to specific needs. The embodiment of the present application does not limit the selected indication method. In this way, the indication method involved in the embodiment of the present application should be understood to cover various methods that can enable the party to be indicated to obtain the information to be indicated.

[0077] The information to be indicated can be sent as a whole, or divided into multiple sub-information and sent separately, and the sending period and / or sending time of these sub-information can be the same or different. The specific sending method is not limited in this application. Among them, the sending period and / or sending time of these sub-information can be predefined, for example, predefined according to the protocol, or configured by the transmitting device by sending configuration information to the terminal device. Among them, the configuration information can, for example, but not limited to, include one or a combination of at least two of RRC signaling, media access control (MAC) layer signaling and physical layer signaling. Among them, MAC layer signaling, for example, includes MAC-control element (CE); physical (PHY) layer signaling, for example, includes downlink control information (DCI).

[0078] Second, in the embodiments of this application, the terms "first," "second," and various numerical numbers are merely distinctions for ease of description and are not intended to limit the scope of the embodiments of this application. For example, they distinguish different indication information. For another example, the terms "first network area" and "second network area" are merely for distinguishing different areas and do not limit their order. Those skilled in the art will understand that terms such as "first" and "second" do not limit the number or order of execution, and that terms such as "first" and "second" do not necessarily define differences.

[0079] Third, in the embodiments of the present application, descriptions such as "when...", "in the case of...", "if" and "if" all mean that under certain objective circumstances, the device (such as a terminal device or an access network device) will make corresponding processing. It does not limit the time, nor does it require the device (such as a terminal device or an access network device) to have a judgment action when implementing it, nor does it mean that there are other limitations.

[0080] Fourth, in the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner to facilitate understanding.

[0081] Fifth, in the embodiments of the present application, "at least one" refers to one or more, and "more" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: the existence of A alone, the existence of A and B at the same time, and the existence of B alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following items" or similar expressions refers to any combination of multiple items, including any combination of single items or plural items. For example, at least one of a, b, or c can represent: a, b, c, ab, ac, bc, or abc, where a, b, c can be single or multiple.

[0082] The embodiments of the present application will present various aspects, embodiments, or features around a system that may include multiple devices, components, modules, etc. It should be understood and appreciated that each system may include additional devices, components, modules, etc., and / or may not include all of the devices, components, modules, etc. discussed in conjunction with the figures. Furthermore, combinations of these solutions may also be used.

[0083] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as wireless fidelity (Wi-Fi) systems, vehicle to everything (V2X) communication systems, device-to-device (D2D) communication systems, Internet of Vehicles communication systems, 4th generation (4G) mobile communication systems, such as long term evolution (LTE) systems, world-wide interoperability for microwave access (WiMAX) communication systems, 5G mobile communication systems, such as new radio (NR) systems, and future communication systems, such as 6G mobile communication systems.

[0084] The following introduces the communication system and applicable network elements involved in the embodiments of the present application, as well as related terms.

[0085] 1. RRC status

[0086] In the 5G communication system, the RRC state may include the RRC idle state (idle), the RRC inactive state (inactive), and the RRC connected state (connected). Both the idle state and the inactive state may be referred to as the non-connected state. When the terminal device has no signaling and / or service data to receive or send, the terminal device may enter the idle state or the inactive state to reduce the power consumption of the terminal device.

[0087] (1) Idle state

[0088] The idle state refers to the state in which a terminal device is stationed in a cell but has not yet performed a random access procedure. In other words, the terminal device is not connected to an access network device. A terminal device typically enters the idle state after being powered on or after the RRC connection is released. When a terminal device is in the idle state, the air interface connection between the terminal device and the access network device is disconnected, context information is no longer stored, the terminal device only receives limited downlink information, and does not send uplink information.

[0089] For example, in the idle state, the terminal device can perform processes such as public land mobile network (PLMN) selection, cell selection, cell reselection, and system message broadcasting. Furthermore, in the idle state, since the terminal device is not connected to the access network device, has no network access, does not occupy the service resources of the access network device, and has not obtained the terminal device context and key, it cannot transmit service data.

[0090] It should be understood that uplink information may refer to information sent by a terminal device to an access network device, and downlink information may refer to information sent by an access network device to a terminal device. The limited downlink information may include downlink synchronization information required for the terminal device to complete its residency in a cell, information contained in a master information block (MIB), and information contained in a system information block (SIB) 1 (or remaining minimum system information (RMSI)). For details, please refer to the description of the relevant 3GPP standard protocols, which will not be repeated here.

[0091] It can be understood that the idle state referred to in the embodiments of the present application generally refers to the radio resource control RRC idle state unless otherwise specified.

[0092] (2) Connection state

[0093] The connected state corresponds to the idle state, and refers to the state in which the terminal device is in after completing the random access process but not releasing the RRC connection, that is, the state in which the terminal device is in after completing the connection with the access network device. When the terminal device is in the connected state, it establishes an air interface connection with the access network device and communicates with the access network device based on the air interface connection. When the terminal device is in the idle state, after the terminal device completes the random access process, the state of the terminal device migrates to the connected state. When the terminal device is in the connected state, after completing the RRC connection release, the state of the terminal device migrates to the idle state. In the connected state, the terminal device can obtain the context and key from the access network device to use the context and key to transmit service data.

[0094] For example, the terminal device can enter the connected state from the idle state. For example, in the idle state, the terminal device can establish an RRC connection with the access network device by sending an RRC message, such as an RRC connection establish request message, to the access network device, thereby entering the connected state. Alternatively, the terminal device can also enter the connected state from the inactive state. For example, in the inactive state, the terminal device can restore the RRC connection with the access network device by sending an RRC message, such as an RRC resume request message, to the access network device, thereby entering the connected state. In addition, in the connected state, the terminal device can also be released to the idle state or the inactive state according to an RRC message sent by the access network device, such as an RRC release message, thereby reducing resource overhead, reducing power consumption, and improving the battery life of the terminal device.

[0095] It can be understood that the connection state referred to in the embodiments of the present application generally refers to the radio resource control RRC connection state unless otherwise specified.

[0096] (3) Inactive state

[0097] The inactive state is a state between the connected state and the idle state. For a terminal device in the inactive state, the user plane bearer of the air interface has been suspended, while the user plane bearer and control plane bearer between the access network device and the core network (CN) are still maintained. When the terminal device initiates a call or service request, it is necessary to activate the user plane bearer of the air interface and reuse the existing user plane bearer and control plane bearer between the access network device and the CN. It can be understood that when the terminal device is in the inactive state, the air interface connection between the terminal device and the access network device is disconnected, but the context information continues to be saved. When the terminal device enters the connected state from the inactive state, the terminal device can quickly recover to the connected state based on the saved context information.

[0098] For example, after a terminal device is released from a connected state to an inactive state, it can delete the key but retain the context so that it can quickly return to the connected state later. In the inactive state, the terminal device can perform cell reselection and send RRC messages, such as RRC recovery request messages, to perform early data transmission to reduce resource overhead and improve communication efficiency. In addition, in the inactive state, the terminal device can receive RRC messages, such as an RRC release message, enter the idle state, and delete the context.

[0099] It can be understood that the inactive state referred to in the embodiments of the present application generally refers to the RRC inactive state unless otherwise specified, and can also be called the "third state".

[0100] Currently, the terminal device can receive paging in an inactive state or an idle state. For example, in an inactive state, the terminal device can identify RAN paging through a full inactive-radio network temporary identifier (full I-RNTI) or a 5G temporary mobile user identity (5G-S-temporary mobile subscriber identity, 5G-S-TMSI) to identify CN paging. In an idle state, the terminal device can identify CN paging through a 5G-S-TMSI.

[0101] When the terminal device switches from an inactive state to another state, such as an idle state or a connected state, the terminal device needs to clear or release the suspend configuration information element in the RRC release message saved in the inactive state. The suspend configuration information element may include fullI-RNTI, shortI-RNTI, the cycle for access network to initiate paging (ran-pagingCycle), access network update area information (ran-notificationAreaInfo), frequency hopping configuration (nextHopChainingCount), timer (timer), such as T380 and other parameters. The above parameters can be used by the terminal device to establish or restore the RRC connection with the network side. The specific functions and related introductions of each parameter can be referred to the relevant introduction in "Section 5.3 of 38331" in 3GPP, which will not be repeated here.

[0102] 2. Integrated sensing and communication (ISAC)

[0103] ISAC can also be referred to as joint communications and sensing (JCS) or joint communications and sensing (JCAS). In 6G mobile communication systems, higher frequency bands (millimeter wave and even terahertz), wider bandwidths, and larger antenna arrays enable high-precision, high-resolution perception. This makes ISAC possible within a single system, allowing communication and perception functions to complement each other. On the one hand, the entire communication network can function as a massive sensor. Network elements transmit and receive wireless signals, leveraging the transmission, reflection, and scattering of radio waves to better perceive and understand the physical world. By extracting distance, speed, and angle information from wireless signals, a wide range of new services can be provided, including high-precision positioning, gesture capture, motion recognition, passive object detection, imaging, and environmental reconstruction, realizing the "Network as a Sensor." On the other hand, the high-precision positioning, imaging, and environmental reconstruction capabilities provided by perception can help improve communication performance, for example, by enabling more accurate beamforming and faster recovery from beam failures, enabling "perception-assisted communication." Perception also serves as a "new channel" for observing and sampling the physical and biological worlds, connecting them to the digital world. Future application scenarios of the 6GISAC system are likely to include ultra-high-precision positioning, synchronous imaging, map construction, and human sensory enhancement.

[0104] The perception process is achieved using perception signals. Perception signals can refer to signals used to perceive or detect targets, or to perceive or detect environmental information. For example, perception signals can be electromagnetic waves sent by access network equipment to perceive environmental information.

[0105] The echo signal is the signal generated by the perception signal passing through the perception target in the environment. The time delay of the echo signal relative to the transmitted perception signal reflects the distance of the perception target; the Doppler frequency shift of the echo signal relative to the transmitted perception signal reflects the speed of the perception target.

[0106] In the embodiment of the present application, the perception signal is a signal obtained by the perception target being acted upon, and may also be referred to as a signal obtained by the perception signal being reflected by the perception target, a signal obtained by the perception signal being refracted by the perception target, a signal obtained by the perception signal being diffracted by the perception target, a signal obtained by the perception signal being transmitted through the perception target, a signal obtained by the perception signal being scattered or diffracted by the perception target, and the like, without specific limitation.

[0107] Perception targets can include various tangible objects on the ground, such as mountains, forests, and buildings. They can also include movable objects such as vehicles and terminal devices. A perception target is a target that can be perceived by access network devices with perception capabilities and can feed electromagnetic waves back to the access network devices. A perception target can also be referred to as a detected target, perceived object, detected object, or perceived device, without limitation.

[0108] It is understood that the aforementioned sensing targets can be moving or stationary, and can be active or passive. Active refers to sensing targets with data processing capabilities, such as base stations, mobile phones, routers, vehicles, drones, and radio frequency identification (RFID) devices. Passive refers to sensing targets without data processing capabilities, such as humans, animals, plants, vehicles, and buildings.

[0109] 3. Perception Mode

[0110] In the current 3rd Generation Partnership Project (3GPP) discussions, it has been determined that the sensing modes can be divided into the following six modes:

[0111] (1) Base station self-transmission and self-reception: The sensing signal is sent by the base station, reflected by the target in the environment, and then the echo signal is received by the base station.

[0112] (2) Base station A transmits and base station B receives: The sensing signal is sent by base station A, reflected by the target in the environment, and then the echo signal is received by base station B.

[0113] (3) Base station sends and terminal device receives: The sensing signal is sent by the base station, reflected by the target in the environment, and then the echo signal is received by the terminal device.

[0114] (4) The terminal device sends and the base station receives: The sensing signal is sent by the terminal device, reflected by the target in the environment, and then the base station receives the echo signal.

[0115] (5) Terminal device sends and receives signals on its own: The sensing signal is sent by the terminal device, reflected by the target in the environment, and then the echo signal is received by the terminal device.

[0116] (6) Terminal device A transmits and terminal device B receives: The sensing signal is sent by terminal device A, reflected by the target in the environment, and then the echo signal is received by terminal device B.

[0117] 4. Beam

[0118] Beamforming is a special, directional transmission or reception effect created by the antenna array of a network device or terminal's transmitter or receiver, similar to the beam formed by a flashlight that focuses light in a single direction. Transmitting and receiving signals using beamforming can effectively increase signal transmission distance.

[0119] The beam can be a wide beam, a narrow beam, or other types of beams. The beam forming technology can be beamforming technology or other technologies. The beamforming technology can specifically be digital beamforming technology, analog beamforming technology, or hybrid digital / analog beamforming technology.

[0120] Beams generally correspond to resources. For example, when performing beam measurement, the network device measures different beams using different resources, and the terminal feeds back the measured resource quality, allowing the network device to know the quality of the corresponding beam. During data transmission, beams can also be indicated by their corresponding resources. For example, the network device indicates a transmission configuration indication-state through the transmission configuration index (TCI) field in the DCI, and the terminal determines the beam corresponding to the reference resource based on the reference resource contained in the TCI-state.

[0121] In communication protocols, beams can be specifically characterized as digital beams, analog beams, spatial domain filters, spatial filters, spatial parameters, TCIs, TCI-states, etc. A beam used to transmit signals can be called a transmission beam (or Tx beam), a spatial domain transmission filter, a spatial transmission filter, a spatial domain transmission parameter, or a spatial transmission parameter. A beam used to receive signals can be called a reception beam (or Rx beam), a spatial domain reception filter, a spatial reception filter, a spatial domain reception parameter, or a spatial reception parameter.

[0122] It can be understood that the embodiments of the present application uniformly use beams for description, but beams can be replaced by other equivalent concepts and are not limited to the concepts mentioned above.

[0123] 5. Basic process of wireless sensing

[0124] According to the IMT-2020 discussion report, "5G-Advanced Intersensory Integration Air Interface Technology Research Report," for the six sensing modes mentioned above, while the network element interactions involved may vary, the sensing process is essentially the same. As shown in Figure 1, it generally consists of three steps: sensing capability reporting, sensing measurement configuration, and sensing measurement reporting.

[0125] Perception capability reporting is usually the first step in the perception process. Its function is for the terminal device and / or access network device to report the supported perception modes and capabilities related to perception signal processing, thereby helping the SF or access network device to determine the appropriate perception mode and perception resources to use. Perception measurement configuration is the second step in the perception process. Its purpose is to enable the terminal device and / or access network device to determine the allocation of perception resources based on the perception requirements after receiving the perception requirements sent by the SF. In the perception measurement configuration process, the access network device is a network element that must participate and is responsible for the allocation of air interface resources. Therefore, this process exists in the interaction between the SF and the access network device, and between the access network device and the terminal device. Perception measurement reporting is the last step in the perception process. Its purpose is to report the collected perception measurement results to the SF or the service terminal device. In different perception modes, the reporting network element can be the terminal device or the access network device.

[0126] In the above perception process, there are the following problems:

[0127] 1. Perception terminal device selection: During the measurement process, only one terminal device is selected for measurement at a time. Simultaneous measurement of multiple devices is not supported. Therefore, the current perception measurement process may not support the selection of multiple terminal devices for perception, and cannot meet the requirements of some perception services where the network requires multiple terminal devices to participate in perception simultaneously.

[0128] 2. Configuration and reporting: When a terminal device is in a connected state, the access network device sends an RRC reconfiguration message to configure the measurement for the terminal device. Therefore, the current perception measurement process may not support the terminal device to directly configure perception in a non-connected state, nor support the terminal device to report perception data in a non-connected state. In addition, when the access network device performs perception configuration for a terminal device in a connected state, it can configure the uplink perception measurement resources allocated to the terminal device, but cannot support the terminal device to perform downlink perception.

[0129] Therefore, it can be seen that the current perception process cannot realize the perception measurement configuration and reporting of the terminal device in the non-connected state. Therefore, the embodiment of the present application provides a perception method that can realize the perception configuration and reporting of the terminal device in the non-connected state.

[0130] For example, Figure 2 is a schematic diagram of the architecture of a communication system provided in an embodiment of the present application. As shown in Figure 2, the communication system includes a terminal device, an access network device, an access and mobility management network element, and a perception network element, which can communicate with each other.

[0131] 1. Terminal equipment

[0132] The terminal device may be one or more, such as a first terminal device, a second terminal device, a third terminal device, etc. The terminal device may be a terminal device with transceiver functions, or may be a chip or chip system provided in the terminal device. The terminal device may also be referred to as user equipment (UE), access terminal, subscriber unit (subscriber unit), subscriber station, mobile station (MS), mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device. The terminal device in the embodiments of the present application can be a mobile phone, a cellular phone, a smart phone, a tablet computer, a wireless data card, a personal digital assistant (PDA), a wireless modem, a handheld device (handset), a laptop computer, a machine type communication (MTC) terminal, a computer with wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a smart home device (for example, a refrigerator, a television, an air conditioner, an electric meter, etc.), an intelligent robot, a robotic arm, a workshop equipment, a wireless terminal in unmanned driving, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical care, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, a vehicle-mounted terminal, a roadside unit with terminal function, a roadside control unit (ROU), ... The terminal device of the present application may also be an onboard module, onboard module, onboard component, onboard chip or onboard unit built into a vehicle as one or more components or units. The terminal device may also be other devices with terminal functions, for example, a terminal device may also be a device that functions as a terminal in D2D communication.

[0133] The embodiments of this application do not limit the device form factor of the terminal. The device used to implement the functions of the terminal device can be the terminal device; it can also be a device that supports the terminal device to implement the functions, such as a chip system. The device can be installed in the terminal device or used in conjunction with the terminal device. In the embodiments of this application, the chip system can be composed of chips or include chips and other discrete devices.

[0134] 2. Access network equipment

[0135] Access network equipment may also be referred to as access network (radio access network, RAN) nodes, network equipment, RAN entities or access nodes, etc., located on the network side of the above-mentioned communication system, used to help terminal devices achieve wireless access, and has wireless transceiver functions or can be set in the chip or chip system of the device. The access network equipment includes but is not limited to: base station (base station), evolved NodeB (eNodeB), access point (AP), transmission reception point (TRP), next generation NodeB (gNB), next generation base station in 6G mobile communication system, base station in future mobile communication system, or access node in Wi-Fi system, etc. The access network equipment can be a macro base station, micro base station or indoor station, relay node or donor node, open radio access network (ORAN), or a wireless controller in a centralized radio access network (CRAN) scenario. Optionally, the RAN node can also be a server, wearable device, vehicle or vehicle-mounted device, etc. For example, the access network equipment in V2X technology can be a road side unit (RSU). All or part of the functions of the access network device in this application may also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform). The access network device in this application may also be a logical node, logical module, or software that can implement all or part of the functions of the access network device.

[0136] In another possible scenario, multiple RAN nodes collaborate to assist terminal devices in achieving wireless access, and different RAN nodes respectively implement part of the functions of the base station. For example, the RAN node can be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU can be set separately, or they can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0137] 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 the ORAN system, CU may also be called O-CU (Open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, this application uses CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0138] The embodiments of this application do not limit the form of the access network device. The device used to implement the functions of the access network device can be the access network device; it can also be a device that supports the access network device to implement the functions, such as a chip system. The device can be installed in the access network device or used in conjunction with the access network device.

[0139] 3. Access and mobility management network elements

[0140] The access and mobility management network element is a device deployed in the core network to provide services for terminal devices, and is used to implement access management and mobility management of terminal devices. For example, it is responsible for the status maintenance of terminal devices, the reachability management of terminal devices, the forwarding of non-access-stratum (NAS) messages of non-mobility management (MM), the forwarding of session management (SM) N2 messages, etc. For example, when the method of the embodiment of the present application is applied to a 5G system, the access management network element may be the AMF in the 5G system. For another example, when the method of the embodiment of the present application is applied to an LTE system, the access and mobility management network element may be a mobility management entity (MME).

[0141] 4. Perception Network Elements

[0142] A perception network element (NE) is a device deployed in the core network to implement perception functions in a telepresence integration scenario. It can be an independent NE or integrated with other NEs, and can be deployed in a centralized or distributed manner. A perception NE can select perception devices, control perception services, process perception measurement data independently or in conjunction with other NEs, and output perception measurement results to the perception requester. For example, a perception NE can be a SF.

[0143] It should be understood that the communication system shown in Figure 2 may also include other core network elements, other terminal devices, or other access network devices, such as data management network elements and policy control network elements, without limitation. The data management network element may be a unified data management (UDM) in a 5G system, and the policy control network element may be a policy control function (PCF) in a 5G system.

[0144] In an embodiment of the present application, each communication device, such as an access network device and a terminal device, is equipped with multiple antennas, which may include at least one transmitting antenna for sending signals and at least one receiving antenna for receiving signals. In addition, each communication device also additionally includes a transmitter chain and a receiver chain. Those skilled in the art will understand that they may include multiple components related to signal transmission and reception (such as processors, modulators, multiplexers, demodulators, demultiplexers or antennas, etc.). Therefore, communication devices can communicate with each other through multi-antenna technology. Specifically, the communication device is equipped with an antenna array, and the antenna array elements in the antenna array can be used for sensing as well as for communication. In other words, each communication device can send multiple sensing signals and / or communication signals at the same time, and the antenna array of the communication device has sensing and communication functions.

[0145] During perception, access network equipment and terminal equipment may also be referred to as perception equipment, perception devices, perception communication equipment, perception equipment, perception communication equipment, etc., without limitation.

[0146] It should be noted that the solutions in the embodiments of the present application can also be applied to other communication systems, and the corresponding names can also be replaced by the names of corresponding functions in other communication systems.

[0147] The perception method provided in the embodiment of the present application will be described in detail below with reference to Figures 3-5.

[0148] For example, FIG3 is a flowchart of a perception method provided in an embodiment of the present application. This communication method can be applied to the communication between the terminal device, access network device, access and mobility management network element, and perception network element shown in FIG2 . The subject that performs the terminal device actions in this method may also be a device / module in the terminal device, such as a chip, processor, or processing unit in the terminal device, and this embodiment of the present application does not specifically limit this. The subject that performs the access network device actions in this method may also be a device / module in the access network device, such as a chip, processor, or processing unit in the access network device, and this embodiment of the present application does not specifically limit this. The subject that performs the access and mobility management network element actions in this method may also be a device / module in the access and mobility management network element, such as a chip, processor, or processing unit in the access and mobility management network element, and this embodiment of the present application does not specifically limit this. The subject that performs the perception network element actions in this method may also be a device / module in the perception network element, such as a chip, processor, or processing unit in the perception network element, and this embodiment of the present application does not specifically limit this.

[0149] As shown in Figure 3, the perception method includes:

[0150] S301: A first access network device sends a paging message, and a first terminal device receives the paging message accordingly.

[0151] Among them, the paging message is used to page the terminal device belonging to the first perception group, that is, the paging message includes information for indicating the first perception group, so that the terminal device can determine that the perception group information stored by it is consistent with the perception group information carried in the paging message. If they are consistent, that is, it belongs to the first perception group, it responds to the paging message; if they are inconsistent, it does not respond to the paging message. For example, the information for indicating the first perception group can be the identification (ID) of the first perception group, or an index for indirectly indicating the identification of the first perception group, which is not limited to this.

[0152] It should be understood that in the embodiment of the present application, the first access network device pages a terminal device in a non-connected state, which includes an idle state and an inactive state. In other words, the first access network device determines the terminal device in the non-connected state that belongs to the first perception group by paging.

[0153] For any terminal device within the coverage of the first access network device, taking the first terminal device as an example, the first terminal device can correspond to at least one perception group. Different perception groups can be divided based on different conditions. The first terminal device can identify whether the perception group indicated in the paging message matches its assigned perception group. The perception group to which the first terminal device belongs can be pre-configured to the first terminal device by the first access network device.

[0154] In one possible implementation, before sending a paging message, the first access network device sends an RRC release message to the first terminal device. Accordingly, the first terminal device receives the RRC release message from the first access network device. The RRC release message includes information for indicating the perception group to which the first terminal device belongs, and the perception group to which the first terminal device belongs includes the first perception group. That is, the first terminal device is in a connected state before receiving the RRC release message, and the first access network device can configure the perception group information to the first terminal device in the RRC release message indicating that the first terminal device changes from a connected state to a non-connected state.

[0155] It should be understood that before sending the paging message, the first access network device can also send perception packet information through other RRC messages, MAC messages, etc. when the first terminal device is in a connected state. Afterwards, the first access network device can execute the conversion from the connected state to the non-connected state for the first terminal device according to the release request of the first terminal device.

[0156] The perception groups to which terminal devices belong can be divided according to the perception capabilities of the terminal devices. Terminal devices can be divided into different perception groups based on different perception capabilities. The perception capabilities of terminal devices may include the perception modes supported by the terminal devices, the perception measurement accuracy supported by the terminal devices, the perception calculation rate of the terminal devices, the perception distance supported by the terminal devices, etc. For example, terminal devices can be grouped according to the perception distances supported by the terminal devices, and terminal devices with supported perception distances in different ranges can be divided into different perception groups, each of which has a perception group identifier.

[0157] In an embodiment of the present application, the division of perception groups can be performed by the access network device or by the perception network element, and the perception network element then sends the divided perception group information to the access network device, and the access network device then distributes the perception group information of the perception group to which each terminal device belongs.

[0158] In one possible design scheme, the first access network device can send a paging message based on the triggering of the access and mobility management network element. In this design scheme, the first access network device can receive a first message from the access and mobility management network element and send a paging message based on the first message. The first message is used to request the first access network device to perform perception configuration for the terminal devices belonging to the first perception group. That is, the first message also includes information for indicating the first perception group, and the access and mobility management network element triggers the first access network device to page the terminal device, so that the first access network device performs perception configuration for the terminal devices that meet the paging conditions to complete the perception task to be performed.

[0159] In one possible implementation, the first message may further include information indicating an area where the sensing task is to be performed. The information indicating an area where the sensing task is to be performed may be represented by a number of geographic coordinates (e.g., longitude and latitude), where the geographic area enclosed by the plurality of geographic coordinates represents the area where the sensing task is to be performed. The area where the sensing task is to be performed may also be represented by other methods such as center coordinates + radius, without limitation.

[0160] Therefore, the first access network device can determine the direction and number of paging beams for sending paging messages based on the information used to indicate the area where the perception task is performed, so that the area where the perception task is performed is covered by the paging beam, so as to quickly determine the terminal device that meets the paging conditions within the perception area.

[0161] In some possible implementations, the information used to indicate the area where the perception task is performed may also be referred to as perception area information, perception area indication information, etc., without limitation.

[0162] Optionally, the first message may further include a second perception configuration, where the second perception configuration is used to indicate a period for performing measurement and / or reporting of the perception task within a preset time. Exemplarily, the second perception configuration may include at least one of the following: information indicating the perception task, information indicating the periodic performance of measurements of the perception task, information indicating the reporting of measurement results of the periodic performance of the perception task, information indicating the time for performing the perception task, or information indicating the area for performing the perception task.

[0163] The information used to indicate a perception task is used to indicate a certain type of perception of a certain type of target. For example, the target type can be a vehicle, building, tree, drone, etc., and the perception type can be ranging, angle measurement, speed measurement, frequency measurement, imaging, etc. In some possible implementations, the information used to indicate a perception task can also be referred to as perception session information, perception session identifier, perception task identifier, etc., without limitation. The perception session corresponds to the perception task and can be understood as the session used to complete the perception task, without limitation.

[0164] The information used to indicate the periodic execution of the measurement of the perception task is used to indicate how often the terminal device executes the measurement of the perception task, and the information used to indicate the reporting of the measurement results of the periodic execution of the perception task is used to indicate how often the terminal device reports the perception measurement results of the perception task. In some possible implementations, the information used to indicate the periodic execution of the measurement of the perception task may also be referred to as perception measurement period information, perception task execution period information, etc., and the information used to indicate the reporting of the measurement results of the periodic execution of the perception task may also be referred to as perception reporting period information, reporting period information, perception result reporting period information, etc., without limitation.

[0165] The information used to indicate the time for performing the perception task is used to indicate the time requirement for the terminal device to perform a measurement of the perception task. The start time of the terminal device performing a measurement of a perception task may be the time when the terminal device receives the echo signal, and the end time may be the time when the terminal device calculates the perception measurement result based on the echo signal. For a measurement that is not completed within the required time, the terminal device may discard the perception measurement result or not report the perception measurement result. Alternatively, the information used to indicate the time for performing the perception task is used to indicate the time requirement for the terminal device to perform the measurement to complete the entire perception task, that is, how long the terminal device is required to complete the measurement of the entire perception task. In some possible implementations, the information used to indicate the time for performing the perception task may also be referred to as perception measurement timing information, measurement duration threshold information, etc., which is not limited to this. In addition, the information used to indicate the area for performing the perception task can be found in the above description and will not be repeated here.

[0166] It should be understood that in addition to the several types of perception configuration information shown above, the second perception configuration may also include other configuration information related to the execution of the perception task, such as information for indicating the time to end the execution of the perception task, information for indicating the time to start the execution of the perception task, etc., without limitation.

[0167] In the above design, the access and mobility management network element may send a first message based on a trigger from the perception network element. In one possible implementation, the perception network element sends a fourth message to the access and mobility management network element. Accordingly, the access and mobility management network element receives the fourth message from the perception network element and sends the first message based on the fourth message. The fourth message is used to request the access and mobility management network element to instruct at least one access network device to perform perception configuration for terminal devices belonging to a first perception group, where the first access network device is one of the at least one access network devices.

[0168] That is, after the access and mobility management network element receives the fourth message sent by the perception network element, it triggers one or more access network devices to page the terminal devices belonging to the first perception group according to the fourth message, and performs perception configuration for the paged terminal devices. In one example, the fourth message may include an identifier of at least one access network device and information for indicating the first perception group. The identifier of at least one access network device may be indicated in the form of a list, such as a gNB id list. It should be understood that the at least one access network device may be all access network devices managed by the access and mobility management network element, or may be a part of them, and this is not limited.

[0169] In one possible implementation, the fourth message may also include a second perception configuration, that is, the perception network element may issue relevant configurations for performing the perception task, and the access and mobility management network element may instruct at least one access network device (including the first access network device) to perform perception configuration for the paging terminal device.

[0170] In one possible implementation, the paging message may also include information indicating a sensing task. In this case, the paging message specifically instructs terminal devices belonging to the first sensing group to perform the sensing task. That is, the first access network device notifies the terminal devices belonging to the first sensing group of the sensing task to be performed during the paging process, and may also notify the terminal devices belonging to the first sensing group of the sensing task to be performed after the paging is completed.

[0171] Therefore, for a terminal device that receives a paging message, for example, the first terminal device, it must determine whether its assigned perception group matches the first perception group indicated by the paging message. If so, the first terminal device prepares to receive the perception configuration issued by the first access network device to perform the corresponding perception task. If not, the first terminal device does not need to obtain the perception configuration issued by the first access network device. The following S302 explains how a matching terminal device obtains the perception configuration required to perform the perception task.

[0172] S302: When the paging is completed, the first access network device sends a first sensing configuration for performing the sensing task. Correspondingly, when the first terminal device belongs to the first sensing group, the first terminal device receives the first sensing configuration for performing the sensing task.

[0173] The first perception configuration may include at least one of the following: information for indicating a perception task, information for indicating measurement of periodic perception tasks, information for indicating reporting of measurement results of periodic perception tasks, information for indicating the time of performing the perception task, information for indicating the area of ​​performing the perception task, or information for indicating resources for performing the perception task. Among them, the information for indicating resources for performing the perception task may indicate one or more of the time-frequency resources used by the first access network device to send the first perception signal, the sequence information constituting the first perception signal, and the time-frequency resources used by the terminal device to report the perception measurement results. Among them, the time-frequency resources used by the first access network device to send the first perception signal are used by the terminal device to receive signals on the corresponding time-frequency resources, the sequence information constituting the first perception signal is used by the terminal device to identify whether the received signal is sent by the first access network device, and the time-frequency resources used by the terminal device to report the perception measurement results are resources allocated to the terminal device for uplink transmission. In addition, for the specific description of other information, please refer to the relevant description in the above S301, which will not be repeated here.

[0174] When the first access network device triggers paging according to the first message of the access and mobility management network element, and the first message includes the second perception configuration, the first perception configuration may be determined by the first access network device according to the second perception configuration.

[0175] In one possible design, paging completion may mean that the first access network device waits for a period of time after sending a paging message, during which a terminal device that meets the paging conditions (such as the first terminal device) feeds back a response to the first access network device, at which point the connection state of the terminal device that meets the paging conditions changes. In this design, the terminal device that meets the paging conditions may send a request message to the first access network device to request recovery from a non-connected state to a connected state in order to obtain the first configuration information.

[0176] For the first terminal device in the idle state, the first terminal device can send an RRC setup message to the first access network device, and accordingly, the first access network device receives the RRC setup message from the first terminal device. For the first terminal device in the inactive state, the first terminal device can send an RRC resume request message to the first access network device, and accordingly, the first access network device receives the RRC resume request message from the first terminal device.

[0177] When the first terminal device returns to a connected state, the first access network device sends first configuration information to the first terminal device. In one possible implementation, the first access network device sends an RRC reconfiguration message to the first terminal device, and the first terminal device receives the RRC reconfiguration message from the first access network device. The RRC reconfiguration message includes the first perception configuration.

[0178] In this implementation, after the first terminal device obtains the first perception configuration, the first access network device can send an RRC release message to the first terminal device so that the first terminal device is in a non-connected state again. In the non-connected state, the perception task is performed according to the first perception configuration, which can reduce the energy consumption of the terminal.

[0179] In another possible implementation, the first access network device sends an RRC release message to the first terminal device, and the first terminal device receives the RRC release message from the first access network device. The RRC release message includes the first perception configuration. That is, upon releasing the first terminal device and returning it to a disconnected state, the first access network device sends the first configuration information to the first terminal device, enabling the first terminal device to perform perception tasks according to the first perception configuration while in the disconnected state, thereby reducing energy consumption of the terminal.

[0180] In another possible design scheme, paging completion may mean that the first access network device waits for a period of time after sending a paging message. During this period of time, the terminal device that meets the paging conditions (such as the first terminal device) does not feedback a response to the first access network device. At this time, the terminal device that meets the paging conditions remains in a non-connected state.

[0181] In addition to the above design scheme, the terminal device remains in a non-connected state after receiving the paging message. In one possible scenario, the paging message may also include information for instructing the terminal device belonging to the first perception group to remain in a non-connected state, so as to instruct the terminal device belonging to the first perception group to remain in a non-connected state to receive the perception configuration, without performing connection restoration according to the paging message, that is, without feeding back a response to the first access network device.

[0182] Furthermore, when the terminal device remains in a non-connected state, the first access network can periodically send broadcast messages to perform perception configuration for the terminal device. In one implementation method, the first access network device sends a first broadcast message, and correspondingly, the first terminal device receives the first broadcast message. The first broadcast message includes first configuration information, during which the first terminal device remains in a non-connected state, and receives the first perception configuration in the broadcast message while in a non-connected state. The first broadcast message can be a system information block (SIB) message, such as SIB20, or a predefined dedicated perception configuration broadcast, which is not limited to this.

[0183] In this embodiment of the present application, the sensing mode is that the access network device transmits a sensing signal, and the terminal device receives an echo signal after the sensing signal is acted upon by a sensing target. Thus, after receiving the first configuration information, the first terminal device, while in a disconnected state, receives the echo signal corresponding to the first sensing signal used to perform the sensing task according to the first sensing configuration, and determines a first sensing measurement result based on the echo signal corresponding to the first sensing signal.

[0184] Furthermore, the first terminal device initiates an RRC recovery request message or an RRC establishment message to recover from a non-connected state to a connected state, so as to send a first perception measurement result to the first access network device. In one possible implementation, the first terminal device sends a second message to the first access network device, and accordingly, the first access network device receives the second message from the first terminal device. The second message includes the first perception measurement result, and the second message can be a measurement report message. It should be understood that the second message also includes an identifier of the first terminal device and an identifier of the first access network device.

[0185] Exemplarily, within a preset time length, the first terminal device receives an echo signal corresponding to a first perception signal sent by the first access network device at a corresponding time-frequency position, measures and calculates the echo signal to obtain a first perception measurement result, periodically executes the measurement process, and periodically reports the first perception measurement result.

[0186] In the case where the first access network device does not page the terminal device within the perception area to perform the perception task based on the perception area information, or in the case where the area covered by the paging beam determined by the first access network device based on the perception area information is larger than the perception area within its coverage area, the terminal device that meets the paging conditions (such as the first terminal device) may not be within the perception area for performing the perception task, and the perception measurement result obtained at this time may not be accurate enough.

[0187] In this case, in one possible scenario, the first access network device may also send a second broadcast message in a different direction, and the second broadcast message includes information for indicating whether the first terminal device performs the perception task. For example, the information for indicating whether the first terminal device performs the perception task is indicated by 0 or 1. Among them, 0 indicates that the first terminal device does not perform the perception task in this direction, which can be understood as the area covered by the beam that sends the second broadcast message in this direction does not have a perception area, or it can be understood as the first terminal device is not located in the perception area; 1 indicates that the first terminal device performs the perception task in this direction, which can be understood as the area covered by the beam that sends the second broadcast message in this direction does have a perception area, or it can be understood as the first terminal device is located in the perception area.

[0188] In another possible scenario, the second broadcast message may include a first identifier, which is used to identify that the first terminal device performs the sensing task. It can be understood that the first identifier is a type of information used to indicate whether the first terminal device performs the sensing task in the above scenario.

[0189] Exemplarily, the first identifier may identify a sub-area obtained by dividing a cell by the first access network device, such as dividing the cell covered by the first access network device into four sub-areas 1 to 4, and the four sub-areas are identified by 00, 01, 10, and 11, respectively. For a sub-area in which a perception area exists, such as sub-area 1, when the first access network device sends a second broadcast message in sub-area 1, the second broadcast message carries the identifier 00 of sub-area 1. The first terminal device obtains the identifier 00 of sub-area 1 through the second broadcast message and may perform the perception task according to the first configuration information. It should be understood that the first terminal device is located in sub-area 1. For a sub-area in which no perception area exists, such as sub-area 2, when the first access network device sends a second broadcast message in sub-area 2, the second broadcast message may not carry the identifier of sub-area 2 to indicate to the first terminal device that it is not located in the perception area and does not need to perform the perception task, thereby reducing the energy consumption of the terminal device.

[0190] That is to say, if the first terminal device obtains the first identifier in the second broadcast message, or the second broadcast message carries the first identifier, the first terminal device can determine that it is located in the perception area and can perform the perception task. If the first terminal device cannot obtain the first identifier in the second broadcast message, or the second broadcast message does not carry the first identifier, the first terminal device can determine that it is not located in the perception area and does not need to perform the perception task. In other words, the first terminal device performs the perception task according to the first identifier and the first configuration information, such as receiving an echo signal corresponding to the first perception signal used to perform the perception task, and measuring the echo signal to obtain a first perception measurement result.

[0191] In this scenario, after the first terminal device obtains the first perception measurement result, the first perception measurement result may carry a first identifier. Thus, the first access network device can determine, based on the first identifier, the area within which the first terminal device measured the corresponding first perception measurement result. In other words, the first access network device divides cells at a finer granularity and associates the divided cell areas with perception areas, allowing the first terminal device to reduce useless measurements and reports and perform perception tasks more accurately.

[0192] In one possible scenario, when the first terminal device is performing a perception task, if a cell reselection occurs, such as the first terminal device reselects from the first access network device to the second access network device, the perception area is distributed under both the first access network device and the second access network device. At this time, when the first terminal device is under the coverage of the second access network device, the second access network device may also send a third broadcast message in different directions. The third broadcast message carries information or a first identifier for indicating whether the first terminal device performs the perception task, so as to indicate whether the first terminal device is located in the perception area and whether the perception task can be performed. For specific implementation, please refer to the above-mentioned description of the first access network device sending the second broadcast message, which will not be repeated here.

[0193] In this scenario, since the first terminal device has reselected, the perception measurement result sent by it to the second access network device may include a first perception measurement result and a second perception measurement result. The first perception measurement result is determined by the first terminal device based on an echo signal corresponding to a first perception signal sent by the first access network device for performing a perception task, that is, measured within the perception area of ​​the first access network device; the second perception measurement result is determined by the first terminal device based on an echo signal corresponding to a second perception signal sent by the second access network device for performing a perception task, that is, measured within the perception area of ​​the second access network device.

[0194] Furthermore, after receiving the perception measurement results, the first access network device or the second access network device may send the perception measurement results to the perception network element. In one possible implementation, the first access network device sends a third message to the perception network element, and the perception network element receives the third message from the first access network device. The third message includes the first perception measurement results. It should be understood that the third message also includes the identifier of the first terminal device and the identifier of the first access network device.

[0195] It should be understood that different access network devices can be assigned the same perception task or different perception tasks, and there is no limitation on this.

[0196] Based on the perception method shown in FIG3 , the first access network device can page the terminal devices in the non-connected state belonging to the first perception group through a paging message, and when the paging is completed, the perception configuration is performed for the terminal devices in the non-connected state that meet the paging conditions. In this way, not only can it be avoided that all terminal devices with perception capabilities respond to the paging after the paging is initiated, thereby reducing the pressure on the network connection, but also the efficiency of the perception configuration can be improved. Furthermore, by performing perception configuration on the terminal devices in the non-connected state, the terminal devices can perform perception measurements in the non-connected state, which can reduce the energy consumption of the terminal devices and further reduce the pressure on the network connection.

[0197] The sensing method shown in Figure 3 is described in detail below, with reference to specific application scenarios. This description uses as an example the following example: UE1 and UE3 meet the paging conditions, UE2 and UE4 do not meet the paging conditions, the first access network device is gNB1, the second access network device is gNB2, the access and mobility management network element is the AMF, and the sensing network element is the SF.

[0198] For example, FIG4 is a flow chart of another sensing method provided in an embodiment of the present application. As shown in FIG4 , the sensing method includes the following steps:

[0199] S401. The SF sends message #1 to the AMF. Correspondingly, the AMF receives message #1 from the SF.

[0200] Message #1 is used to request the AMF to instruct gNB1 and gNB2 to perform sensing configuration for UEs belonging to sensing group 1. Message #1 includes the AMF ID, sensing task ID, sensing group 1 ID, gNB1 ID, gNB2 ID, sensing area information, sensing measurement period information, sensing reporting period information, and sensing measurement time information. For a detailed description of the sensing task, sensing group, sensing area information, sensing measurement period information, sensing reporting period information, and sensing measurement time information, please refer to the relevant description in S301 above and will not be repeated here.

[0201] S402: The AMF sends message #2 to gNB1. In response, gNB1 receives message #2 from the AMF.

[0202] Message #2 is used to request gNB1 to perform sensing configuration for UEs belonging to sensing group 1. Message #2 includes the sensing task ID, sensing group 1 ID, gNB1 ID, sensing area information, sensing measurement period information, sensing reporting period information, and sensing measurement time information.

[0203] S403. The AMF sends message #3 to gNB2. In response, gNB1 receives message #3 from the AMF.

[0204] Message #3 is used to request gNB2 to perform sensing configuration for UEs belonging to sensing group 1. Message #3 includes the ID of sensing task 1, the ID of the sensing group, the gNB2 ID, sensing area information, sensing measurement period information, sensing reporting period information, and sensing measurement time information.

[0205] S404: gNB1 sends paging message #1 based on message #2. In response, UE1 and UE2 receive paging message #1.

[0206] Among them, paging message #1 is used to page UE belonging to perception group 1 to perform perception task 1, and paging message #1 includes the ID of perception task 1 and the ID of perception group 1.

[0207] For example, gNB1 can determine the beam range for sending paging message #1 based on the perception area information of message #2, so that only non-connected UEs within the perception area are paged, and the efficiency of perception configuration is improved in combination with location information.

[0208] After receiving paging message #1, UE1 and UE2 determine whether they belong to sensing group 1. UE1 determines that it belongs to sensing group 1 and executes the following S406. UE2 determines that it does not belong to sensing group 1, does not respond to gNB1, and does not participate in sensing configuration.

[0209] S405. gNB2 sends paging message #2 according to message #3. In response, UE3 and UE4 receive paging message #2.

[0210] Among them, paging message #2 is used to page the UE belonging to perception group 1 to perform perception task 1, and paging message #1 includes the ID of perception task 1 and the ID of perception group 1.

[0211] After receiving paging message #2, UE3 and UE4 determine whether they belong to sensing group 1. UE3 belongs to sensing group 1 and executes S407 below. UE4 does not belong to sensing group 1, does not respond to gNB2, and does not participate in sensing configuration.

[0212] For example, gNB2 can determine the beam range for sending paging message #2 based on the perception area information of message #3, so that only non-connected UEs within the perception area are paged, thereby improving the efficiency of perception configuration in combination with location information.

[0213] S406. UE1 sends RRC setup message #1 to gNB1. In response, gNB1 receives RRC setup message #1 from UE1.

[0214] Among them, RRC establishment request #1 is used to request to restore from the idle state to the connected state.

[0215] S407: UE3 sends an RRC resume request message #1 to gNB2. In response, gNB2 receives the RRC resume request message #1 from UE3.

[0216] The RRC recovery request message #1 is used to request recovery from the inactive state to the connected state.

[0217] S408a: gNB1 sends RRC reconfiguration message #1 to UE1. In response, UE1 receives RRC reconfiguration message #1 from gNB1.

[0218] RRC reconfiguration message #1 carries perception configuration #1, which includes UE1 ID, perception measurement period information, perception reporting period information, perception measurement time information, and perception resource information. For a detailed description of perception configuration #1 and the following perception configuration #2, refer to the description of the first perception configuration in S301 above and are not repeated here.

[0219] S408b: gNB1 sends an RRC release message #1 to UE1. In response, UE1 receives the RRC release message #1 from gNB1.

[0220] The above S408a and S408b can be replaced by:

[0221] S408c: gNB1 sends RRC release message #2 to UE1. In response, UE1 receives RRC release message #2 from gNB1.

[0222] Among them, RRC release message #2 carries perception configuration #1.

[0223] In step S409a, gNB2 sends RRC reconfiguration message #2 to UE3. In response, UE3 receives RRC reconfiguration message #2 from gNB1.

[0224] The RRC reconfiguration message #2 carries the perception configuration #2, which includes the UE3 ID, perception measurement period information, perception reporting period information, perception measurement time information, and perception resource information.

[0225] S409b: gNB2 sends RRC release message #3 to UE3. In response, UE3 receives RRC release message #3 from gNB2.

[0226] The above S408a and S408b can be replaced by:

[0227] S409c: gNB2 sends RRC Release message #4 to UE3. In response, UE3 receives RRC Release message #4 from gNB2.

[0228] Among them, RRC release message #4 carries perception configuration #2.

[0229] S410: gNB1 sends sensing signal #1. Accordingly, UE1 receives echo signal #1 corresponding to sensing signal #1 according to sensing configuration #1.

[0230] For example, after completing sensing configuration, UE1 returns to a non-connected state after S408b or S408c. In the non-connected state, UE1 receives echo signal #1 corresponding to sensing signal #1 according to the time-frequency position at which gNB1 transmitted sensing signal #1 in sensing configuration #1, and calculates sensing measurement result #1 based on echo signal #1. When the reporting period is reached or reporting is required, UE1 executes S412 to resume the connected state and report the sensing measurement results.

[0231] In step S411, gNB2 sends sensing signal #2. Accordingly, UE3 receives echo signal #2 corresponding to sensing signal #2 according to sensing configuration #2.

[0232] For example, after completing the sensing configuration, UE3 returns to the unconnected state after S408b or S408c described above. In the unconnected state, UE3 receives echo signal #2 corresponding to sensing signal #1 according to the time-frequency position at which gNB2 transmitted sensing signal #2 in sensing configuration #2, and calculates sensing measurement result #2 based on echo signal #2. When the reporting period is reached or reporting is required, UE3 executes S414 described below to restore the connected state and report the sensing measurement results.

[0233] S412: UE1 sends RRC Setup message #2 to gNB1. In response, gNB1 receives RRC Setup message #2 from UE1.

[0234] S413. UE1 sends Report Message #1 to gNB1. In response, gNB1 receives Report Message #1 from UE1.

[0235] When in the connected state, UE1 sends report message #1, which includes perception measurement result #1, UE1 ID and gNB1ID.

[0236] S414: UE3 sends RRC Recovery Request message #2 to gNB2. In response, gNB2 receives RRC Recovery Request message #2 from UE3.

[0237] S415. UE3 sends Report Message #2 to gNB2. In response, gNB2 receives Report Message #2 from UE3.

[0238] When in the connected state, UE3 sends report message #2, which includes perception measurement result #2, UE3 ID and gNB2ID.

[0239] S416. gNB1 sends Report Message #3 to SF. Accordingly, SF receives Report Message #3 from gNB1.

[0240] Among them, report message #3 includes perception measurement result #1, UE1 ID and gNB1 ID.

[0241] S417. gNB1 sends Report Message #4 to SF. Accordingly, SF receives Report Message #4 from gNB1.

[0242] Among them, report message #4 includes perception measurement result #2, UE3 ID and gNB2 ID.

[0243] As shown in Figure 4, in the sensing scenario where the gNB transmits and the UE receives, the SF triggers the AMF to instruct the gNB to page. UEs that meet the paging conditions, paged by the gNB, return to the connected state and perform sensing configuration. After completing the sensing configuration, the UE is released to the unconnected state, where it performs sensing and periodically returns to the connected state for sensing reporting. This reduces network connection pressure and enhances sensing configuration efficiency. Furthermore, after the gNB pages the UE, the UE can also remain in the unconnected state for sensing configuration, perform sensing in the unconnected state, and then periodically return to the connected state for sensing reporting.

[0244] For example, FIG5 is a flow chart of another sensing method provided in an embodiment of the present application. As shown in FIG5 , the sensing method includes the following steps:

[0245] S501. The SF sends message #1 to the AMF. Correspondingly, the AMF receives message #1 from the SF.

[0246] Message #1 is used to request the AMF to instruct gNB1 to perform sensing configuration for UEs belonging to sensing group 1. Message #1 includes the AMF ID, sensing task ID, sensing group 1 ID, gNB1 ID, sensing area information, sensing measurement period information, sensing reporting period information, and sensing measurement time information. For a detailed description of the sensing task, sensing group, sensing area information, sensing measurement period information, sensing reporting period information, and sensing measurement time information, please refer to the relevant description in S301 above and will not be repeated here.

[0247] S502: The AMF sends message #2 to gNB1. In response, gNB1 receives message #2 from the AMF.

[0248] Message #2 is used to request gNB1 to perform sensing configuration for UEs belonging to sensing group 1. Message #2 includes the sensing task ID, sensing group 1 ID, gNB1 ID, sensing area information, sensing measurement period information, sensing reporting period information, and sensing measurement time information.

[0249] S503. gNB1 sends paging message #1 according to message #2.

[0250] Correspondingly, UE1 and UE2 receive paging message #1, which is used to page UEs belonging to sensing group 1 to perform sensing task 1. Paging message #1 includes the ID of sensing task 1 and the ID of sensing group 1.

[0251] For example, gNB1 can determine the beam range for sending paging message #1 based on the perception area information of message #2, so that only non-connected UEs within the perception area are paged, and the efficiency of perception configuration is improved in combination with location information.

[0252] After receiving paging message #1, UE1 and UE2 determine whether they belong to sensing group 1. UE1 determines that it belongs to sensing group 1 and remains in a disconnected state, continuing to execute the following step S504. UE2 determines that it does not belong to sensing group 1, does not respond to gNB2, and does not participate in sensing configuration.

[0253] S504: gNB1 sends broadcast message #1. UE1 receives broadcast message #1.

[0254] Broadcast message #1 carries perception configuration #1, which includes UE1 ID, perception measurement period information, perception reporting period information, perception measurement time information, and perception resource information. A detailed description of perception configuration #1 can be found in the description of the first perception configuration in S301 above and is not repeated here. Thus, after receiving perception configuration #1, UE1 performs perception task 1 according to perception configuration #1.

[0255] In one possible scenario, if gNB1 does not determine the beam range for sending paging message #1 based on the sensing area information, gNB1 may divide the cell range it covers into several sub-areas, such as four sub-areas 1-4, each corresponding to a sub-area identifier, such as 00-11. gNB1 then determines which of the divided sub-areas have sensing areas based on the sensing area information and sends broadcast messages in different sub-areas. Broadcast messages for sub-areas with sensing areas carry the sub-area identifier, while broadcast messages for sub-areas without sensing areas do not carry the sub-area identifier. UEs meeting the paging conditions in each sub-area determine whether to perform sensing tasks based on whether the sub-area identifier is present. Therefore, when reporting sensing measurement results, the obtained sub-area identifier may be included in the sensing measurement results to indicate to gNB1 the area in which the UE's sensing measurement results were measured.

[0256] S505: gNB1 sends sensing signal #1. Accordingly, UE1 receives echo signal #1 corresponding to sensing signal #1 according to sensing configuration #1.

[0257] The specific implementation process of S505 can refer to the relevant description of S410 or S411 above, and will not be repeated here.

[0258] S506. UE1 sends RRC Setup Request #1 to gNB1. In response, gNB1 receives RRC Setup Request #1 from UE1.

[0259] For example, when the reporting period is reached or reporting is required, UE1 needs to send an RRC establishment request #1 to recover from the idle state to the connected state.

[0260] S507. UE1 sends Report Message #1 to gNB1. In response, gNB1 receives Report Message #1 from UE1.

[0261] When in the connected state, UE1 sends a report message #1 to gNB1, where the report message #1 includes the perception measurement result #1, UE1 ID, and gNB1 ID.

[0262] S508. gNB1 sends report message #2 to SF. Accordingly, SF receives report message #2 from gNB1.

[0263] Among them, report message #2 includes perception measurement result #1, UE1 ID and gNB1 ID.

[0264] In one possible scenario, if UE1 reselects from gNB1 to gNB2 while performing the sensing task, the following steps may also be included:

[0265] S509. gNB2 sends broadcast message #2.

[0266] Broadcast message #2 includes a first identifier. Exemplarily, the first identifier is the identifier of the sub-area into which gNB2 divides its coverage area. In this scenario, gNB2 may also divide its coverage area in the same manner as gNB1 in S504 above, sending broadcast message #2 within the undivided sub-area. Broadcast messages within sub-areas where sensing areas exist carry the identifier of the sub-area, while broadcast messages within sub-areas where sensing areas do not exist do not carry the identifier of the sub-area. UEs meeting the paging conditions within each sub-area determine whether to perform sensing tasks based on whether the sub-area identifier is present.

[0267] S510: gNB2 sends sensing signal #2. Accordingly, UE1 receives echo signal #2 corresponding to sensing signal #2 based on the first identifier and sensing configuration #1.

[0268] After receiving the first identifier, UE1 determines that it needs to perform sensing task 1. It then receives echo signal #2 corresponding to sensing signal #2 according to sensing configuration #1, and calculates sensing measurement result #2 based on echo signal #2. When the reporting period is reached or reporting is required, UE1 executes S511 below to resume the connected state and report the sensing measurement result.

[0269] S511: UE1 sends RRC Setup Request #2 to gNB2. In response, gNB2 receives RRC Setup Request #2 from UE1.

[0270] S512: UE1 sends report message #3 to gNB2. In response, gNB2 receives report message #3 from UE1.

[0271] In the connected state, UE1 sends Report Message #3, which includes Perception Measurement Result #1, UE1 ID, and gNB1 ID, as well as Perception Measurement Result #2, UE1 ID, and gNB2 ID. This means that UE1 can report both the perception measurement results before and after reselection to the reselected gNB, i.e., gNB2.

[0272] S513. gNB2 sends report message #4 to SF. Accordingly, SF receives report message #4 from gNB2.

[0273] Among them, report message #4 may include perception measurement result #1, UE1 ID and gNB1 ID, as well as perception measurement result #2, UE1 ID and gNB2 ID.

[0274] Figure 5 illustrates the sensing method. In a sensing scenario where the gNB transmits and the UE receives, the SF triggers the AMF to instruct the gNB to page. UEs matching the paging criteria remain in a non-connected state, reading broadcast messages for sensing configuration and measurement, and then periodically return to a connected state for sensing reporting. This reduces network connection pressure and UE energy consumption. If the gNB does not page based on sensing area information, the gNB can also indicate whether the non-connected UE is within the sensing area and whether to perform sensing measurements by including a first identifier in the broadcast message. This not only enables more granular management of sensing areas, but also reduces unnecessary measurements and reporting by the terminal device.
