Description

Communication method, device and system

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on September 26, 2023, with application number 202311267624.5 and invention name “Communication Methods, Devices and Systems”, the entire contents of which are incorporated by reference into this application. Technical Field

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

[0003] Communication and perception integration is a key technology in future wireless communication systems. It aims to integrate wireless communication and perception into a single system, leveraging the various propagation characteristics of wireless signals to achieve perception functions such as target positioning, detection, imaging, and identification. This allows for information about the surrounding physical environment, improved communication performance, and enhanced user experience. Current technologies primarily rely on single-station autonomous transmission and reception. However, this is prone to coverage blind spots, and significant path loss during the transmission and reception process can lead to poor perception. Dual-station collaborative sensing technology can address this blind spot issue, but the signals and beams between the receiving and transmitting base stations cannot be identified, making it difficult to perform perception tasks.

If an Xn connection has been established between the network devices, the perception resource configuration can be directly coordinated through the Xn interface, reducing the interaction of the N2 interface, completing the perception resource configuration faster, and further shortening the delay of the perception resource configuration.

[0091] The technical solution in this application will be described below with reference to the accompanying drawings.

[0092] The technical solutions provided in this application can be applied to various communication systems, such as new radio (NR) systems, long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, etc. The technical solutions provided in this application can also be applied to device-to-device (D2D) communication, vehicle-to-everything (V2X) communication, machine-to-machine (M2M) communication, machine type communication (MTC), and Internet of Things (IoT) communication systems or other communication systems.

[0093] In a communication system, the part operated by an operator may be referred to as a public land mobile network (PLMN), or as an operator network, etc. PLMN is a network established and operated by the government or an operator approved by it for the purpose of providing land mobile communication services to the public. It is mainly a public network in which mobile network operators (MNOs) provide mobile broadband access services to users. The PLMN described in the embodiments of the present application may specifically be a network that complies with the standards of the 3rd Generation Partnership Project (3GPP), referred to as a 3GPP network. 3GPP networks generally include but are not limited to fifth-generation mobile communication (5th-generation, 5G) networks, fourth-generation mobile communication (4th-generation, 4G) networks, and other future communication systems, such as (6th-generation, 6G) networks.

[0094] As mobile communication technologies evolve, 5G networks will be built in a flexible and efficient manner. 5G networks can utilize communication awareness as a new capability. For ease of description, the system architecture of a 5G network is used as an example.

[0095] FIG1 is a schematic diagram of a network architecture 100 applicable to the present application, wherein FIG1(a) is a schematic diagram of a 5G network architecture based on a point-to-point interface. The network architecture may include but is not limited to the following network elements (or referred to as functional network elements, functional entities, nodes, devices, etc.): user equipment (UE), (radio) access network (R)AN), user plane function (UPF) network element, data network (DN), access and mobility management function (AMF) network element, session management function (SMF) network element, policy control function (PCF) network element, application function (AF) network element, network slice selection function (NSSF), authentication server function (AUSF), unified data management (UDM) network element, network exposure function (NEF) network element, unified data repository (UDR) network element, etc.

[0096] The following briefly introduces the network elements shown in Figure 1 (a):

[0097] 1. UE: A terminal that communicates with an (R)AN. It may also be referred to as a terminal device, access terminal, user unit, user station, mobile station, mobile station (MS), mobile terminal (MT), remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device. In this application, a terminal device may have a sensing capability. For example, a radio frequency module of a terminal device may transmit radio frequency signals and then understand the environment by receiving and processing reflected signals. Therefore, in this application, a terminal device may also detect and / or collect sensing data.

[0098] 2. (R)AN: RAN is used to provide network access functions for authorized terminal devices in a specific area, and can use transmission tunnels of different qualities according to the level of the terminal device, business requirements, etc. RAN can manage wireless resources, provide access services for terminal devices, and then complete the forwarding of control signals and terminal device data between the terminal device and CN. RAN can also be understood as a base station in a traditional network. In this application, when the base station adopts the millimeter wave frequency band for wireless communication, the base station will naturally have radar-like perception capabilities, that is, the base station will have both wireless communication capabilities and perception capabilities. Therefore, RAN can detect and / or collect perception data, and the RAN in this application can also be referred to as a communication radar integrated base station, which can not only achieve communication service coverage for ground users, but also detect flying targets such as drones, helicopters, birds, and ground vehicle traffic, pedestrians, etc.

[0099] 3. UPF: includes user plane functions such as packet routing and transmission, packet detection, service usage reporting, quality of service (QoS) processing, legal monitoring, uplink packet detection, downlink packet storage, etc.

[0100] 4. DN: A network used to transmit data. After accessing the network, a terminal device can establish a protocol data unit (PDU) session and access the DN through the PDU session. It can interact with the application function network elements deployed in the DN. Depending on the DN accessed by the user, the network can select the UPF connected to the DN as the PDU Session Anchor (PSA) based on network policies and access the application function network elements through the N6 interface of the PSA.

[0101] 5. AMF: Mainly used for mobility management and access management, it can be used to implement other functions of the mobility management entity (MME) in addition to session management, such as lawful interception and access authorization / authentication.

[0102] 6. SMF: Mainly used for session management, allocation and management of Internet protocol (IP) addresses of terminal devices, selection of endpoints of manageable terminal device plane functions, policy control and charging function interfaces, and downlink data notification.

[0103] 7. PCF: A unified policy framework used to guide network behavior and provide policy rule information for control plane functional network elements (such as AMF, SMF network elements, etc.).

[0104] 8. AF: Application function network elements can interact with the 5G system through application function network elements to access network open function network elements or interact with the policy framework for policy control, etc.

[0105] 9. NSSF: Mainly includes the following functions: selecting a group of network slice instances for the UE, determining the allowed network slice selection assistance information (NSSAI), and determining the AMF set that can serve the UE.

[0106] 10. AUSF: Used for authentication services, generating keys to achieve two-way authentication of terminal devices, and supporting a unified authentication framework.

[0107] 11. UDM / UDR: This handles terminal device identification, access authentication, registration, and mobility management. It can refer to the user database and can serve as a single logical repository for user data.

[0108] 12. NEF: Used to provide customized functions for network openness. 5G communication systems can also use NEF network elements to open 5GC-supported capabilities to external application function network elements, such as providing small data transmission capabilities.

[0109] It is understood that the above network elements or functions can be physical entities in hardware devices, software instances running on dedicated hardware, or virtualized functions instantiated on a shared platform (e.g., a cloud platform). Simply put, an NF can be implemented by hardware or software.

[0110] Figure 1(b) is a schematic diagram of a 5G network architecture based on a service-oriented interface. The network architecture may include but is not limited to the following network elements (or referred to as functional network elements, functional entities, nodes, devices, etc.): UE, (R)AN, UPF network element, DN, AMF network element, SMF network element, PCF network element, AF network element, NSSF network element, AUSF network element, UDM network element, NEF network element, UDR network element, etc. For the introduction of the functions of each network element, please refer to the introduction of the corresponding network element functions in Figure 1(a), which will not be repeated here.

[0111] In (a) and (b) of Figure 1, Nnssf, Nnef, Nnrf, Npcf, Nudm, Nudr, Naf, Nausf, Namf, Nsmf, N1, N2, N3, N4, N6 and N9 are interface serial numbers. For example, the meaning of the above interface serial numbers can be found in the meaning defined in the 3GPP standard protocol, and this application does not limit the meaning of the above interface serial numbers. It should be noted that the interface name between the various network functions in (a) and (b) of Figure 1 is only an example. In a specific implementation, the interface name of the system architecture may also be other names, which is not limited by this application. In addition, the name of the message (or signaling) transmitted between the above-mentioned network elements is also only an example and does not constitute any limitation on the function of the message itself.

[0112] It should be understood that the above network architecture is only an example of a network architecture described from the perspective of a service-oriented architecture, and the network architecture applicable to the embodiments of the present application is not limited thereto. Any network architecture that can implement the functions of the above-mentioned network elements is applicable to the embodiments of the present application. The communication perception method provided in the embodiments of the present application may also involve network elements not shown in Figure 1. Of course, the communication perception method provided in the embodiments of the present application may also include only some of the network elements shown in Figure 1.

[0113] It should also be understood that the above naming is only defined to facilitate the distinction between different functions and should not constitute any limitation to this application. This application does not exclude the possibility of adopting other naming in 5G networks and other future networks. For example, in a 6G network, some or all of the above network elements may continue to use the terminology in 5G, or may adopt other names. For example, a wireless access network device may be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation base station (next generation NodeB, gNB) in a fifth-generation (5G) mobile communication system, a next-generation base station in a sixth-generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system; it may also be a module or unit that performs part of the functions of a base station, for example, a centralized unit (CU) or a distributed unit (DU). The CU here completes the functions of the base station's radio resource control protocol and packet data convergence protocol (PDCP), and can also complete the function of the service data adaptation protocol (SDAP); the DU completes the functions of the base station's radio link control layer and medium access control (MAC) layer, and can also complete part of the physical layer or all of the physical layer. For detailed descriptions of the above protocol layers, please refer to the relevant technical specifications of the 3rd Generation Partnership Project (3GPP).

[0114] In the present application, the network architecture 100 may further include a location management service function (LMF) network element for initiating a positioning process of a terminal device and obtaining location information of the terminal device.

[0115] In the present application, the network architecture 100 may also include a perception network element, such as a sensing function (SF) network element. The perception network element is responsible for end-to-end enabling of perception services. For example, the perception network element obtains perception requirements based on internal network requirements or the requirements of the demander of the perception service. After obtaining the perception requirements, the perception network element triggers the access network device or terminal device to detect and / or collect perception data. In the present application, the perception network element can communicate with other network elements, such as RAN, AMF, SMF, LMF and other network elements.

[0116] It should be noted that in a 5G network, the perception network element may be one of the network elements of the 5G core network (5G core, 5GC). Alternatively, the perception network element may also be a non-core network element. Alternatively, the perception network element may be deployed independently. Alternatively, the perception network element may also be a sub-network element or module in the 5GC network element. For example, the perception network element may be deployed in combination with the AMF, UPF, SMF, or LMF network element, which is not particularly limited in this application.

[0117] Figure 2 is a schematic diagram of a network architecture 200 for cognitive communication applicable to the present application. As shown in Figure 2 , network architecture 200 includes cognitive network elements (e.g., a sensing function (SF)), at least one RAN network element with cognitive capabilities, and at least one UE with cognitive capabilities. For example, Figure 2 shows cognitive network element 210, RAN 220 and RAN 230, and UE 240 and UE 250. The cognitive network element 210 is responsible for end-to-end enabling of cognitive services.

[0118] For example, the perception network element 210 can obtain perception requirements based on internal network requirements or requirements of the demander of the perception service. After obtaining the perception requirements, the perception network element 210 triggers the RAN 220 and / or RAN 230 to detect and / or collect perception data. For example, the RAN 220 sends a perception signal to the UE 240 and receives an echo signal from the UE 240, and / or the RAN 230 sends a perception signal to the UE 250 and receives an echo signal from the UE 250. The RAN 220 and RAN 230 each perform certain processing based on the received echo signals to generate perception data. It should be understood that the echo signal refers to the reflection signal of the perception signal after it passes through an object. The RAN 220 and / or RAN 230 then provide the perception data to the perception network element 210, which then provides perception services to the demander based on the perception data, such as the AF, an external application server (AS), or a terminal device. Alternatively, the perception network element 210 can optimize the network internally based on the perception data.

[0119] It should be understood that Figures 1 and 2 are merely exemplary communication network architectures, and this application does not make any specific limitations on this. Any network architecture that can implement the functions of the above-mentioned network elements is applicable to the embodiments of this application.

[0120] During wireless communications, electromagnetic waves propagate through space, transmitting signals and carrying environmental information. For example, if a mobile phone receives a weak Wi-Fi signal, it may be because the phone is far away from the wireless router. A sudden drop in Wi-Fi signal strength may indicate that the phone has entered a specific enclosed space, such as an elevator. Using the received signal strength indicator (RSSI) as a feature, we can infer the phone's location and surroundings. The selection of signal features has a critical impact on perception accuracy, reliability, and model generalization.

[0121] For example, radar sensing is a common wireless sensing technology. By analyzing the characteristics of received target echoes, it can extract and discover the target's position, shape, motion characteristics, and trajectory, and further infer characteristics of the target and its environment. Radar technology excels in motion detection. It uses the Doppler effect on target echoes to observe and interpret the target's motion, such as direction and speed. Using multi-channel sensors, it can also observe target motion from different perspectives. By capturing the target's motion from different perspectives and analyzing it in combination with instantaneous and historical information, it can resolve complex motion.

[0122] With the development of 5G networks, the demand for new perception-based network capabilities is gradually emerging. For example, in certain scenarios such as smart cities and smart transportation, there is a growing need to obtain the relative position and angle between objects, as well as to perceive information such as the distance, speed, and shape of target objects. To meet these business needs, 5G networks must be further enhanced to provide sensing capabilities that assist wireless networks. In the future, 5G networks may deploy integrated radar and communication base stations to enhance base station sensing capabilities. The radar's precise sensing capabilities enable precise communication and improve communication efficiency. For example, base station communication resources and sensing resources can be time-division multiplexed or space-division multiplexed to achieve perception of the surrounding environment or objects. Perception functions can be used in security scenarios where cameras are not suitable. For example, in certain industrial parks, it can detect intrusions by flying objects such as drones. In traffic scenarios, roadside stations can perform functions such as traffic flow statistics and vehicle navigation, all of which require roadside base stations to have sufficient perception capabilities.

[0123] 5G terminals can also have perception capabilities to achieve perception of the surrounding environment or objects. For example, the terminal sends a perception measurement signal and collects the perception signals reflected on other objects in the surrounding environment. This measurement mode can be called self-transmission and self-reception (i.e., UE sends and UE receives). For another example, the terminal sends a perception measurement signal and other UEs collect the perception signals reflected on other objects in the surrounding environment. This measurement mode can be called self-transmission and self-reception (i.e., UE sends and other UEs receive). For example, during the driving of a vehicle, the vehicle as a UE can use a self-transmission and self-reception method to perform perception of a small range of surrounding environment, such as detecting the surrounding traffic conditions. Due to the complex road environment, the UE's own perception of the surrounding environment has certain limitations (e.g., during driving, there may be occlusion in a certain direction around the vehicle). The UE can obtain perception information of the surrounding environment with the help of other UEs.

[0124] It is understandable that different perception modes have different requirements on terminal capabilities. In different application scenarios, different perception modes can be used to perceive and measure the surrounding environment.

[0125] Figure 3 is a schematic diagram of a perception scenario provided by an embodiment of the present application. As shown in Figure 3, when the source UE (Source UE) is driving, the target area in front (such as a road construction area) is blocked by the vehicle in front (candidate UE#2), so it is unable to detect the target area using its own perception capability. The source UE can request other UEs (called candidate UEs) to assist the source UE in obtaining perception information of the target area. However, the distance between the source UE and the candidate UE will affect the direction in which the candidate UE performs perception measurements. For example, the target area is located behind candidate UE#1, and candidate UE#1 needs to send the perception information behind the vehicle to the source UE. The target area is located in front of candidate UE#2, and candidate UE#2 needs to send the perception information in front of the vehicle to the source UE. The source UE determines the situation of the target area based on the perception information of candidate UE#1 and candidate UE#2.

[0126] Current sensing technologies can achieve this through autonomous transmission and reception by network devices, such as base stations. The base station transmits a sensing signal, which is physically reflected and then received by the base station. Since the base station knows the transmitted sensing signal it is using, it can directly use the transmitted sensing signal and the reflected sensing signal for target detection. Furthermore, since the base station sends the sensing signal in a single direction, it can receive the strongest echo signal in that direction, facilitating target detection. However, single-station autonomous transmission and reception is prone to coverage blind spots. Dual-station collaborative sensing technology, where base station A transmits and base station B receives, can address this blind spot problem. However, unlike autonomous transmission and reception, when base station A transmits and base station B receives, the receiving base station cannot know the sensing signal used by the transmitting base station, making it difficult for the receiving base station to detect targets. Furthermore, if base station A transmits and base station B receives, the base station may use beamforming technology. During beam scanning, the transmitting and receiving base station's beams may not be in the same detection space at the same time, preventing the receiving base station from receiving the transmitting base station's sensing beam and thus preventing sensing.

[0127] In view of this, the present application proposes a method applicable to a communication system. The method enables different network devices involved in sensing to use unified sensing signals through negotiation between network devices, thereby facilitating the execution of sensing tasks.

[0128] It should be understood that the network device may be any one of the above network elements.

[0129] As shown in FIG4 , the method may include the following steps:

[0130] 410. The core network device sends first information to the first network device. Correspondingly, the first network device receives the first information.

[0131] The first information is used to request the configuration of sensing resources. The sensing resources include time-frequency resources corresponding to the sensing signal. The time-frequency resources include time domain resources and frequency domain resources. In other words, the sensing resources include time domain resources and / or frequency domain resources corresponding to the sensing signal.

[0132] The configuration of time domain resources includes at least one of the following: cyclic prefix length, number of sensing resource symbols, sensing resource symbol repetition period, and sensing resource symbol length. The configuration of frequency domain resources includes the bandwidth and / or comb size used by the sensing signal.

[0133] Optionally, the perception resource also includes a sequence format corresponding to the perception signal. In other words, the perception resource includes a sequence format used to send the perception signal. For example, the sequence format may be a ZC sequence, which includes information such as a root value and a cyclic shift index of the ZC sequence.

[0134] The above-mentioned sensing resources are used to send sensing signals.

[0135] It should be understood that the perception signal in the present application can be a reference signal, such as a channel state information reference signal (CSIRS) or a positioning reference signal (PRS), or a newly defined reference signal that is specifically used for perception.

[0136] Optionally, the first information includes an identifier of a perception task or a perception session, and the first information is used to request configuration of perception resources corresponding to the perception session or perception task. When there are multiple perception sessions, the first information carries the identifier of the perception session or perception task to facilitate accurate acquisition of the perception resources corresponding to the perception session or the perception task.

[0137] 420. The first network device determines a sensing resource according to the first information.

[0138] For example, the first network device determines the time domain resource and / or frequency domain resource of the perception signal according to the first information. Optionally, the first network device further determines the sequence format corresponding to the perception signal according to the first information.

[0139] 430. The first network device sends second information to the core network device. Correspondingly, the core network device receives the second information.

[0140] The second information indicates the sensing resource in 420 .

[0141] 440. The core network device sends third information to the second network device. Correspondingly, the second network device receives the third information.

[0142] The third information indicates the sensing resource in 420. In other words, the third information indicates the sensing resource indicated by the second information in 430.

[0143] Optionally, the third information further includes an identifier of a sensing task or an identifier of a sensing session, which is used to indicate that the sensing resources indicated by the third information are the configuration of sensing resources of the same sensing task or sensing session as in 410 .

[0144] 450. The second network device determines a sensing resource according to the third information.

[0145] It should be understood that the sensing resources determined by the second network device based on the third information are the same as the sensing resources determined by the first network device based on the first information. For example, the time domain resources and / or frequency domain resources corresponding to the sensing signals are the same. Furthermore, the sequence formats corresponding to the sensing signals are the same.

[0146] Optionally, the first network device sends fourth information to the core network device, and the core network device receives the fourth information accordingly. The fourth information indicates the sensing capability of the first network device. The sensing capability includes information such as sensing resolution, sensing accuracy, sensing range, sensing latency, sensing refresh rate, false detection rate, or missed detection rate.

[0147] Optionally, the second network device sends fourth information to the core network device, and correspondingly, the core network device receives the fourth information. The fourth information indicates the perception capability of the second network device.

[0148] That is, the core network device receives N pieces of fourth information, where the N pieces of fourth information respectively indicate sensing capabilities of N network devices, where N is an integer greater than or equal to 2. The N network devices include a first network device and a second network device.

[0149] The core network device can determine the transmitter and receiver of the perception signal based on the perception capabilities of the first network device and the second network device. For example, if the first network device has a stronger perception capability than the second network device, the second network device will serve as the transmitter of the perception signal, and the first network device will serve as the receiver of the perception signal. The first network device will receive and measure the perception signal, thus completing the perception task.

[0150] In another example, the perception capability of the first network device, such as the large perception range of the first network device, and the ability to measure the perception target according to the position and the perception range of the first network device, may enable the first network device to be selected as the transmitter.

[0151] Furthermore, when multiple network devices exist in the communication system, the core network device determines the transmitter and receiver of the perception signal based on the perception capabilities of the multiple network devices. The transmitter and receiver can be one-to-one or one-to-many. For example, a perception signal sent by a transmitter can be received and measured by one receiver or by multiple receivers.

[0152] Specifically, when a core network device receives a sensing service request, it first needs to determine the network devices that can participate in the sensing task and select the appropriate sensing mode and sensing method. There are two ways to determine the network devices that can participate in the sensing task:

[0153] Method 1: The core network device requests the network device to report its sensing capabilities. When the core network device requests the network device to report its sensing capabilities, the core network device first sends a sensing capability request message to the network device. The network device then reports its sensing capabilities to the core network device, including sensing resolution, sensing accuracy, sensing range, sensing latency, sensing refresh rate, and false detection rate or missed detection rate.

[0154] Method 2: The network device periodically reports its sensing capability. In the process of periodically reporting its sensing capability, the network device periodically reports its sensing capability to the core network device without the core network device's request.

[0155] Optionally, the core network device sends fifth information to the first network device, and correspondingly, the first network device receives the fifth information. The fifth information indicates at least one of a sensing task identifier, a sensing session identifier, or a sensing service quality requirement.

[0156] Among them, the perception service quality requirements include perception resolution, perception accuracy, perception range, perception latency, perception refresh rate, false detection rate or missed detection rate, etc.

[0157] In one possible implementation, the fifth information and the first information are carried in the same signaling. That is, the fifth information is also used to request configuration of sensing resources. Based on the fifth information, the first network device may determine at least one of a sensing task, a sensing session, or a sensing quality of service requirement, and configure sensing resources for the sensing task, sensing session, or sensing quality of service requirement.

[0158] In one possible implementation, the second information is carried in a response message. The response message is used to indicate that the perception resource configuration is complete. For example, the first network device sends a response message to the core network device, indicating that the perception resource configuration is complete. The response message also carries the second information indicating the configuration of the perception resource. Alternatively, the second information indicates the perception resource.

[0159] Optionally, when the first network device is a transmitter of the perception signal, the first network device transmits the perception signal on the perception resource. When the second network device is a transmitter of the perception signal, the second network device transmits the perception signal on the perception resource.

[0160] It should be understood that the first information is used to request the configuration of the perception resource and may include two meanings.

[0161] One meaning is that the first information is used to request the first network device to configure sensing resources for the sensing task or sensing session and to feed back information about the configured sensing resources.

[0162] Another meaning is that the first information is used to request the first network device to configure sensing resources for a sensing task or a sensing session. That is, after receiving the first information, the first network device executes the above-mentioned step 420. After the first network device completes the configuration, it can send a response message to the core network device, and the response message is used to indicate that the sensing resource configuration is complete. Furthermore, the core network device sends a sensing resource information request message to the first network device, and the sensing resource information request message is used to request the first network device to feedback information about the configured sensing resources. After receiving the resource information request message, the first network device sends the determined sensing resource information to the core network device. That is, the first information and the sensing resource information request message are sent separately, and the response message and the sensing resource information are also sent separately.

[0163] In this method, a first network device and a second network device are collaborative sites participating in sensing. The sensing resource configuration determined by the first network device is forwarded to the second network device via a core network device, enabling the second network device to accurately receive the sensing signal and perform sensing measurements based on the sensing signal. This allows the receiving end to accurately demodulate the transmitting end's sensing signal, completing the dual-site sensing process.

[0164] The present application also proposes a method that can be applied to a communication system. As shown in FIG5 , the method includes the following steps:

[0165] 510. The core network device sends sixth information to the first network device. Correspondingly, the first network device receives the sixth information.

[0166] The sixth information includes an identifier of the second network device.

[0167] The sixth information is used to request the first network device and the second network device to configure sensing resources. The sensing resources include time-frequency resources corresponding to the sensing signal, which are time domain resources and / or frequency domain resources. Optionally, the sensing resources also include a sequence format corresponding to the sensing signal. For details, please refer to the description in 410 and will not be repeated here.

[0168] That is, the core network device sends a message to the first network device requesting configuration of sensing resources, which also carries the identifier of the second network device. The first network device determines the second network device based on the identifier of the second network device. Furthermore, the first network device determines that the second network device also needs to be configured with the same sensing resources.

[0169] In one possible implementation, a core network device sends identifiers of multiple network devices to a first network device, where the identifiers of the multiple network devices include an identifier of the second network device. For example, the identifier of the network device may be an ID, and the core network device may send an ID list including the identifiers of the multiple network devices to the first network device.

[0170] Optionally, the sixth information further includes a first sensing task quality of service requirement or a first sensing session identifier. The first sensing task quality of service requirement or the first sensing session identifier is used to determine the sensing resource.

[0171] The first network device determines a sensing resource according to the sixth information.

[0172] 520 , the first network device sends seventh information to the second network device, and correspondingly, the second network device receives the seventh information.

[0173] The seventh information indicates the sensing resource in 510. For example, the seventh information includes configuration information of the sensing resource.

[0174] Optionally, the seventh information also includes an identifier of the perception task or perception session.

[0175] The seventh information may be newly designed information for requesting the second network device to establish a sensing resource configuration related to the sensing task. The seventh information may also be information in an existing protocol, such as an Xn Setup message or an NG-RAN node Configuration Update message, which carry the configuration of the sensing resource.

[0176] 530. The second network device determines a sensing resource according to the seventh information.

[0177] Optionally, the second network device sends an eighth message to the first network device, and the first network device receives the eighth message accordingly. The eighth message indicates that the sensing resource configuration is complete. That is, after completing the sensing resource configuration, the second network device feeds back a notification of configuration completion to the first network device.

[0178] Specifically, if the seventh information is a newly designed message, the eighth information is its corresponding response message. If the second message is a message in an existing protocol, its corresponding message may be an Xn Setup Response message or an NG-RAN node Configuration Update Acknowledge message.

[0179] Optionally, the first network device sends ninth information to the core network device, and correspondingly, the core network device receives the ninth information. The ninth information indicates that the first network device and the second network device have completed the configuration of the sensing resource.

[0180] For example, the ninth information includes the identifier of the first network device and a list of identifiers of the senders. It should be understood that when there is only one sender, the ninth information includes the identifier of the sender. When there are multiple senders, the ninth information includes the identifiers of the multiple senders.

[0181] Optionally, the ninth information includes the identifier of the first network device and a list of identifiers of receiving terminals. When there are multiple receiving terminals, the list of identifiers of the receiving terminals includes identifiers of multiple receiving terminals.

[0182] Optionally, the core network device receives N tenth information, each of which indicates the sensing capabilities of N network devices, where N is an integer greater than or equal to 2, and the N network devices include the first network device and the second network device. That is, the first network device and the second network device send the tenth information to the core network device to report their respective sensing capabilities. For details, please refer to the description of the fourth information and sensing capabilities in the embodiment shown in FIG. 4 , and will not be repeated here.

[0183] The core network device determines the first network device as a transmitter and the second network device as a receiver based on the sensing capability. The first network device sends a sensing signal to the second network device on the sensing resource.

[0184] Alternatively, the core network device determines the first network device as the receiving end and the second network device as the sending end based on the sensing capability, and the second network device sends a sensing signal to the first network device on the sensing resource.

[0185] In this method, the cooperative sites participating in the perception (ie, the first network device and the second network device) can unify the configuration of the perception signal, thereby facilitating the receiving end to accurately receive the perception signal and improving the efficiency of the perception measurement.

[0186] Assume that a first network device and a second network device are responsible for sensing the same area. Given the characteristics of high-frequency signals, these devices typically use beamforming to send sensing signals. However, in a scenario where network device A transmits and network device B receives, if both the transmitter and receiver use beamforming, it's possible that their scanning beams may not be directed at the same area at the same time. This can result in the receiver being unable to receive the sensing beam from the transmitter and unable to perform its sensing task.

[0187] In view of this, the embodiment of the present application further proposes a method applicable to a communication system. As shown in FIG6 , the method includes the following steps:

[0188] 610. The core network device sends eleventh information to the first network device. Correspondingly, the first network device receives the eleventh information.

[0189] The eleventh information is used to request the first network device to report a perception beam measurement result, where the perception beam measurement result includes beam information of a perception signal received by the first network device from the second network device, and / or information of a beam used by the second network device to send the perception signal.

[0190] It should be understood that the second network device may use multiple beams to send perception signals, and the beam corresponding to the perception signal received by the first network device may be a part of the multiple beams used by the second network device to send perception signals, or may be all of the multiple beams used by the second network device to send perception signals.

[0191] Optionally, the sensing beam measurement result is the type and number of the sensing beam received by the first network device from the second network device.

[0192] Specifically, because the receiving network device knows the location of the sensing area, the beam of the receiving network device can always be directed in the direction of the sensing area, resulting in a higher received sensing signal strength. For the transmitting network device, the beam of the transmitting network device can be configured omnidirectionally. However, at the current moment, only a certain area may need to be sensed, so the transmitting network device only needs to transmit sensing beams in a few fixed directions. Because the receiving network device does not know the correspondence between the beam configuration and direction of the transmitting network device, the receiving network device needs to obtain information about which beam it can receive from the transmitting network device through measurement. The eleventh information can also be used to request the receiving network device (i.e., the first network device) to send: a sensing task identifier or a sensing session identifier, a list of identifiers of the transmitting network device (including the second network device) (e.g., a transmitting gNB ID list), a beam type, a beam number, a frequency offset, etc. The following steps are all defaulted to this sensing task or sensing session.

[0193] The beam type includes a quasi-co-location relationship between the sensing beam and the synchronization signal block. For example, the beam type is divided into: the sensing beam and the synchronization signal block are quasi-co-located, and the sensing beam and the synchronization signal block are not quasi-co-located.

[0194] 620 : The first network device measures the sensing beam from the second network device according to the eleventh information.

[0195] In one possible embodiment, the eleventh information includes a perception session identifier and an identifier of the second network device. The first network device determines, based on the eleventh information, that the perception beam measurement result of the second network device needs to be reported. The first network device then measures the perception beam from the second network device to obtain the perception beam measurement result.

[0196] In one possible implementation, a first network device sends a beam training request to a second network device, and the second network device receives the beam training request. The beam training request is used to request the second network device to send a sensing beam carrying a sensing session identifier, a sensing beam type, and a sensing beam number.

[0197] For example, both the first network device and the second network device are configured with sensing signals, and then the first network device and the second network device perform beam training. For example, the transmitting base station (the second network device) performs beam scanning, and the receiving base station (the first network device) first uses beam 1 for reception. After the second network device completes the beam scanning, the first network device records whether the currently used beam 1 can receive the transmit beam of the second network device. If so, it records information such as the beam type, beam number, and signal strength. Similarly, after the second network device completes the beam scanning, it can be determined which transmit beams of the second network device the first network device can receive using the current beam. Furthermore, the first network device can filter out the N beams with the strongest signal strength based on the signal strength of each received beam.

[0198] It should be understood that the manner in which the first network device trains the sensing beam is not limited to the above example, and other manners capable of completing beam training are also applicable to the present application.

[0199] It should also be understood that the first network device may also measure the sensing signals of multiple network devices. The first network device may measure the sensing signals of multiple network devices in the same or different ways.

[0200] In one possible manner, the first network device forwards the beam measurement result to the second network device through the core network device, that is:

[0201] 630. The first network device sends a perception beam measurement report to the core network device. Correspondingly, the core network device receives the perception beam measurement report.

[0202] The perception beam measurement report is used to report perception beam measurement results, such as beam type, beam number, and corresponding frequency band information, frequency offset information, and bandwidth information. This beam-related information is used by the second network device to configure the perception signal on the beam. The frequency offset information is used by the second network device to adjust the time domain configuration of the perception signal transmission to align the reception time of the first network device.

[0203] 640. The core network device sends the sensing beam configuration information to the second network device. Correspondingly, the second network device receives the sensing beam configuration information.

[0204] The sensing beam configuration information indicates a sensing beam measurement result.

[0205] Specifically, the core network device may instruct the second network device, using the sensing beam configuration information, which beam to use to send the sensing signal. Furthermore, the second network device may also configure a sensing signal pattern based on the sensing beam measurement result. The pattern is used to indicate the configuration of the sensing signal, such as the location of the time domain resource and / or frequency domain resource of the sensing signal.

[0206] Optionally, the second network device further sends configuration completion information to the core network device, and correspondingly, the core network device receives the configuration completion information. The configuration completion information is used to indicate that the beam information of the second network device has been configured.

[0207] Alternatively, the first network device may directly report the measurement results to the second network device without forwarding them through the core network device. That is, optionally, at 650, the first network device sends a sensing beam measurement report to the second network device, and the second network device receives the sensing beam measurement report.

[0208] The sensing beam measurement report is used to report sensing beam measurement results, such as beam type, beam number, and corresponding frequency band information, frequency offset information, bandwidth information, etc. For example, the sensing beam measurement report can also be used to request the second network device to update the configuration of the sensing signal.

[0209] Optionally, the second network device further sends update completion information to the first network device, and the first network device receives the update completion information accordingly. The update completion information is used to indicate that the configuration of the sensing signal of the second network device has been updated.

[0210] This method ensures that the sensing beams of the transmitting and receiving network devices are located in the same sensing area by exchanging beam (or sensing signal) configuration information between the N2 or Xn interfaces, thereby facilitating smooth execution of sensing tasks by both participating collaborators. Furthermore, it reduces resource waste when the transmitting network device transmits beams omnidirectionally.

[0211] It should be understood that the size of the serial numbers of the above processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0212] It should also be understood that in the various embodiments of the present application, unless otherwise specified or there is a logical conflict, the terms and / or descriptions between different embodiments are consistent and can be referenced to each other, and the technical features in different embodiments can be combined to form new embodiments according to their internal logical relationships.

[0213] It should also be understood that in some of the above embodiments, devices in existing network architectures are mainly used as examples for illustrative purposes, and it should be understood that the embodiments of the present application do not limit the specific form of the devices. For example, devices that can achieve the same functions in the future are applicable to the embodiments of the present application.

[0214] The above description, in conjunction with Figures 1 to 6, details the communication perception method embodiment of the present application. The following description, in conjunction with Figures 7 and 8, details the device embodiment of the present application. It should be understood that the description of the device embodiment corresponds to the description of the method embodiment. Therefore, for portions not described in detail, reference can be made to the above method embodiment.

As shown in Figure 7, the device 700 may include a transceiver unit 710, a processing unit 720, and an acquisition unit 730. The transceiver unit 710 can communicate with the outside, and the acquisition unit 730 can also communicate with the outside.
