Description

Technical Field

[0001] The present application relates to the field of communications, and in particular to a communication method, device and system. Background Art

[0002] Communication and perception integration is a key technology in future wireless communication systems. It aims to integrate wireless communication and perception into the same system, and use the various propagation characteristics of wireless signals to achieve perception functions such as positioning, detection, imaging and identification of targets, so as to obtain information about the surrounding physical environment, improve communication performance and enhance user experience. Current technology mainly focuses on single-station self-transmission and self-reception, but single-station self-transmission and self-reception is prone to coverage blind spots, and the large path loss during the self-transmission and self-reception process can easily lead to poor perception effects. Dual-station collaborative perception technology can solve the problem of blind spots, but the signals and beams between the receiving base station and the transmitting base station cannot be identified, making it difficult to perform perception tasks.

[0091] In the communication system, the part operated by the operator can be called a public land mobile network (PLMN), or 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 (MNO) provide mobile broadband access services to users. The PLMN described in the embodiment of the present application may specifically be a network that meets the requirements of the third generation partnership project (3GPP) standards, 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, etc.

[0092] With the upgrading of mobile communication technology, 5G network will be built in a flexible and efficient way. 5G network can use communication perception as a new capability. For the convenience of description, the system architecture of 5G network is used as an example.

[0093] Figure 1 is a schematic diagram of a network architecture 100 applicable to the present application, Figure 1(a) is a schematic diagram of a 5G network architecture based on a point-to-point interface.

For example, the RF module of the terminal device may send a RF signal and then understand the environment by receiving and processing the reflected signal. Therefore, in the present application, the terminal device may also detect and / or collect perception data.

[0096] 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 equipment, 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 realize communication service coverage for ground users, but also realize detection of flying targets such as drones, helicopters, birds, and ground vehicle traffic, pedestrians, etc.

[0098] 4. DN: A network used to provide data transmission. After the terminal device accesses the network, it can establish a protocol data unit (PDU) session, access the DN through the PDU session, and 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 accessing the DN as the PDU Session Anchor (PSA) according to the network policy, and access the application function network element through the N6 interface of the PSA.

[0099] 5. AMF: Mainly used for mobility management and access management, etc. It can be used to implement other functions of the mobility management entity (MME) except session management, such as lawful monitoring and access authorization / authentication.

[0107] It is understandable 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). In short, an NF can be implemented by hardware or software.

[0108] Figure 1 (b) is a schematic diagram of the 5G network architecture based on the 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. The introduction of the functions of each network element can be referred to Figure 1 The introduction of the corresponding network element functions in (a) will not be repeated here.

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, Figure 1 The interface names between the various network functions in (a) and (b) are only examples. In specific implementations, the interface names of the system architecture may also be other names, which are not limited in this application. In addition, the names of the messages (or signaling) transmitted between the above network elements are only examples and do not constitute any limitation on the functions of the messages themselves.

[0111] It should also be understood that the above naming is only defined for the convenience of distinguishing different functions and should not constitute any limitation to this application. This application does not exclude the possibility of using other names in 5G networks and other future networks. For example, in a 6G network, some or all of the above network elements may use the terms in 5G, or other names may be used. 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 (5th generation, 5G) mobile communication system, a next generation base station in a sixth generation (6th generation, 6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc.; it may also be a module or unit that completes 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 radio resource control protocol and packet data convergence protocol (PDCP) of the base station, and can also complete the function of the service data adaptation protocol (SDAP); the DU completes the functions of the radio link control layer and medium access control (MAC) layer of the base station, and can also complete the functions of part or all of the physical layer. For the specific description of the above-mentioned protocol layers, please refer to the relevant technical specifications of the 3rd Generation Partnership Project (3GPP).

[0112] In the present application, the network architecture 100 may also 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.

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 requirements of the demander of the perception service. After obtaining the perception requirements, the perception network element triggers the access network device or the 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.

[0114] 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 network element of 5GC. For example, the perception network element may be deployed in combination with the AMF, UPF, SMF or LMF network element, and this application does not specifically limit this.

[0115] Figure 2 2 is a schematic diagram of a network architecture 200 for sensing communication applicable to the present application. Figure 2 As shown, the network architecture 200 includes a sensing network element (eg, a sensing function network element (SF)), at least one RAN network element with sensing capability, and at least one UE with sensing capability. Figure 2 The shown network element includes an awareness network element 210, RAN 220 and RAN 230, and UE 240 and UE 250. The awareness network element 210 is responsible for enabling awareness services end-to-end.

[0116] Exemplarily, the perception network element 210 may obtain the perception demand based on the internal demand of the network or the demand of the demand side of the perception service. After the perception network element 210 obtains the perception demand, it triggers the RAN 220 and / or RAN 230 to detect and / or collect the 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 the RAN 230 respectively perform certain processing according to the received echo signal to generate the perception data. It should be understood that the echo signal refers to the reflected signal of the perception signal passing through the object. The RAN 220 and / or the RAN 230 then respectively provide the perception data to the perception network element 210, and the perception network element 210 provides the perception service to the demand side based on the perception data, such as AF, external application server (AS) or terminal equipment. Alternatively, the perception network element 210 may optimize the network internally based on the perception data.

[0117] It should be understood that Figure 1 and Figure 2 This is only an exemplary communication network architecture, 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.

[0118] During wireless communication, electromagnetic waves carry environmental information while transmitting signals in space. For example, if the Wi-Fi signal received by a mobile phone is weak, it may be because the mobile phone is far away from the wireless router; if the strength of the Wi-Fi signal received by the mobile phone drops sharply, it is likely because the mobile phone has entered certain enclosed spaces such as elevators. Using the received signal strength indicator (RSSI) as a feature, the location and environment of the mobile phone can be inferred. The selection of signal features has a key impact on perception accuracy, reliability, and model generalization ability.

[0119] For example, radar sensing is a relatively common wireless sensing technology. By analyzing the characteristics of the received target echo, the position, shape, motion characteristics and motion trajectory of the target can be extracted and discovered, and the characteristics of the target and the environment can be further inferred. The advantage of radar technology is the detection of motion. The Doppler effect of the target echo is used to observe and interpret the motion state of the target, such as the direction and speed of motion; when using a multi-channel sensor, the motion of the target can also be observed from different perspectives. By collecting the motion state of the target from different perspectives and combining instantaneous information with historical information for analysis, complex motion can be resolved.

[0120] With the development of 5G networks, the demand for new network capabilities based on perception is gradually emerging. For example, in some scenarios of smart cities and smart transportation, the need to obtain the relative position and angle between objects, as well as the distance, speed and shape of the target object, is gradually emerging. In order to meet these business needs, the 5G network should be further enhanced to have the ability to assist the wireless network in perception. In the future, 5G can deploy radar communication integrated base stations to enhance the perception capabilities of base stations. The precise perception capabilities of radars can communicate accurately and improve communication efficiency. For example, the communication resources and perception resources of the base station are time-division multiplexed, or space-division multiplexed, to achieve perception of the surrounding environment or objects. The perception function can be used for detection in some security scenarios where cameras cannot be installed. For example, in certain industrial parks, it can detect the intrusion of flying objects such as drones. In traffic scenarios, roadside stations can complete functions such as traffic flow statistics and vehicle navigation. These functions all require roadside base stations to have certain perception capabilities.

[0121] 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 spontaneous self-reception (i.e. UE sends, 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 spontaneous self-reception (i.e. UE sends, other UEs receive). For example, during the driving of a vehicle, the vehicle as a UE can use a spontaneous 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 surroundings 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.

[0122] 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.

[0123] Figure 3 is a schematic diagram of a perception scene provided by an embodiment of the present application. Figure 3 As shown, when the source UE (Source UE) is driving, the target area in front (such as the road construction area) is blocked by the vehicle in front (candidate UE#2), so it cannot detect the target area using its own perception ability. The source UE can request other UEs (called candidate UEs) to assist the source UE in obtaining the 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 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 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.

[0124] In the current perception technology, perception can be completed through network devices, such as base stations, by self-transmission and self-reception. The base station sends the perception signal by itself, which is physically reflected and then received by the base station itself. Since the base station knows the transmitted perception signal it uses, it can directly use the transmitted perception signal and the reflected perception signal for target detection. In addition, since the base station sends the perception signal in one direction, it can receive the strongest echo signal in the current direction, which is convenient for target detection. However, single-station self-transmission and self-reception is prone to coverage blind spots. The dual-station collaborative perception technology can solve the problem of blind spots, that is, base station A sends and base station B receives. However, unlike the base station's self-transmission and self-reception, the receiving base station cannot know the perception signal used by the transmitting base station when base station A sends and base station B receives, making it difficult for the receiving base station to detect the target. In addition, if the base station uses beamforming technology in the scenario where base station A sends and base station B receives, the beams of the transmitting base station and the receiving base station may not be in the same detection space at the same time during the beam scanning process, resulting in the receiving base station being unable to receive the perception beam of the transmitting base station, and thus unable to perform the perception task.

[0125] In view of this, the present application proposes a method applicable to a communication system. The method enables different network devices involved in perception to unify the perception signals used by the network devices through negotiation, thereby facilitating the execution of the perception task.

[0126] It should be understood that the network device may be any one of the above network elements.

[0127] like Figure 4 As shown, the method may include the following steps:

[0128] 410. The core network device sends first information to the first network device, and correspondingly, the first network device receives the first information.

[0129] The first information is used to request the configuration of the perception resource. The perception resource includes the time-frequency resource corresponding to the perception signal. Among them, the time-frequency resource includes the time domain resource and the frequency domain resource. In other words, the perception resource includes the time domain resource and / or the frequency domain resource corresponding to the perception signal.

[0130] The configuration of the time domain resources includes at least one of the cyclic prefix length, the number of sensing resource symbols, the sensing resource symbol repetition period, and the sensing resource symbol length. The configuration of the frequency domain resources includes the bandwidth and / or comb size used by the sensing signal.

[0131] 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, and the sequence format includes information such as a root value and a cyclic shift index of the ZC sequence.

[0132] The above-mentioned sensing resources are used to send sensing signals.

[0133] It should be understood that the perception signal in the present application may be a reference signal, such as a channel state information reference signal (CSI RS) or a positioning reference signal (PRS), or a newly defined reference signal that is specifically used for perception.

[0134] 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 a perception resource corresponding to the perception session or the perception task. When there are multiple perception sessions, the first information carries an identifier of the perception session or the perception task to facilitate accurate acquisition of the perception resource corresponding to the perception session or the perception task.

[0135] 420. The first network device determines a sensing resource according to the first information.

[0136] 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.

[0137] 430. The first network device sends second information to the core network device, and correspondingly, the core network device receives the second information.

[0138] The second information indicates the sensing resource in 420 .

[0139] 440. The core network device sends third information to the second network device, and correspondingly, the second network device receives the third information.

[0140] 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.

[0141] 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 .

[0142] 450. The second network device determines a sensing resource according to the third information.

[0143] It should be understood that the sensing resource determined by the second network device according to the third information is the same as the sensing resource determined by the first network device according to the first information. For example, the time domain resource and / or frequency domain resource corresponding to the sensing signal is the same. Furthermore, the sequence format corresponding to the sensing signal is the same.

[0144] Optionally, the first 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 first network device. The perception capability includes: perception resolution, perception accuracy, perception range, perception delay, perception refresh rate, false detection rate or missed detection rate and other information.

[0145] 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.

[0146] That is, the core network device receives N fourth information, and the N fourth information respectively indicates the 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.

[0147] The core network device can determine the sender and receiver of the perception signal according to the perception capabilities of the first network device and the second network device. For example, if the perception capability of the first network device is stronger than that of the second network device, the second network device acts as the sender of the perception signal, the first network device acts as the receiver of the perception signal, and the first network device receives the perception signal and measures it to complete the perception task.

[0148] As another example, the perception capability of the first network device, such as the first network device having a larger perception range and being able to measure the perception target according to the position of the first network device and the perception range of the first network device, may select the first network device as the transmitter.

[0149] Furthermore, when there are multiple network devices in the communication system, the core network device determines the sender and the receiver of the perception signal according to the perception capabilities of the multiple network devices. The sender and the receiver can be one-to-one or one-to-many. For example, a perception signal sent by a sender can be received and measured by one receiver or by multiple receivers.

[0150] Specifically, when the 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:

[0151] Method 1: The core network device requests the network device to report the perception capability. In the process of the core network device requesting the network device to report the perception capability, the core network device needs to first send a perception capability request message to the network device, and then the network device reports its perception capability to the core network device, including: perception resolution, perception accuracy, perception range, perception delay, perception refresh rate, false detection rate or missed detection rate and other information.

[0152] Mode 2: The network device periodically reports the sensing capability. In the process of the network device periodically reporting the sensing capability, the network device periodically reports its sensing capability to the core network device without the need for a request from the core network device.

[0153] 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.

[0154] 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.

[0155] In a 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 the configuration of the perception resource. The first network device can determine at least one of the perception task, the perception session, or the perception quality of service requirement according to the fifth information, and configure the perception resource for the perception task, the perception session, or the perception quality of service requirement.

[0156] In a possible implementation, the second information is carried in a response message. The response message is used to indicate that the perception resource configuration is completed. For example, the first network device sends a response message to the core network device, and the response message indicates that the first network device perception resource configuration is completed. At the same time, the response message carries the second information, and the second information indicates the configuration of the perception resource. In other words, the second information indicates the perception resource.

[0157] Optionally, when the first network device is a sender of the perception signal, the first network device sends the perception signal on the perception resource. When the second network device is a sender of the perception signal, the second network device sends the perception signal on the perception resource.

[0158] It should be understood that the first information is used to request the configuration of the perception resource and may include two meanings.

[0159] One meaning is that the first information is used to request the first network device to configure sensing resources for the sensing task or the sensing session and to feed back information about the configured sensing resources. That is, the first network device executes steps 420 and 430 above.

[0160] Another meaning is that the first information is used to request the first network device to configure perception resources for a perception task or a perception session. That is, the first network device performs the above-mentioned step 420 after receiving the first information. After the configuration of the first network device is completed, a response message can be sent to the core network device, and the response message is used to indicate that the perception resource configuration is completed. Further, the core network device sends a perception resource information request message to the first network device, and the perception resource information request message is used to request the first network device to feedback the information of the configured perception resources. After receiving the resource information request message, the first network device sends the determined perception resource information to the core network device. That is, the first information and the perception resource information request message are sent separately, and the response message and the perception resource information are also sent separately.

[0161] In the method, the first network device and the second network device are cooperative sites participating in perception, and the configuration of the perception resources determined by the first network device is forwarded to the second network device through the core network device, so that the second network device can accurately receive the perception signal and further perform perception measurement based on the perception signal. This enables the receiving end to accurately demodulate the perception signal of the sending end, completing the dual-station perception process.

[0162] The present application also provides a method, which can be applied to a communication system. Figure 5 As shown, the method comprises the following steps:

[0163] 510. The core network device sends sixth information to the first network device. Correspondingly, the first network device receives the sixth information.

[0164] The sixth information includes an identifier of the second network device.

[0165] The sixth information is used to request the first network device and the second network device to configure the perception resource. The perception resource includes the time-frequency resource corresponding to the perception signal, and the time-frequency resource is a time domain resource and / or a frequency domain resource. Optionally, the perception resource also includes a sequence format corresponding to the perception signal. For details, please refer to the description in 410, which will not be repeated here.

[0166] That is, the core network device sends information requesting configuration of the sensing resource to the first network device, and the information also carries the identifier of the second network device. The first network device determines the second network device according to the identifier of the second network device. Furthermore, the first network device determines that the second network device also needs to configure the same sensing resource.

[0167] In a possible implementation, the core network device sends the identifiers of multiple network devices to the first network device, and the identifiers of the multiple network devices include the identifier of the second network device. For example, the identifier of the network device may be an ID, and the core network device sends the identifiers of the multiple network devices to the first network device by sending an ID list, and the ID list includes the identifiers of the multiple network devices.

[0168] Optionally, the sixth information further includes a first perception task service quality requirement or a first perception session identifier. The first perception task service quality requirement or the first perception session identifier is used to determine the perception resource.

[0169] The first network device determines a sensing resource according to the sixth information.

[0170] 520. The first network device sends seventh information to the second network device. Correspondingly, the second network device receives the seventh information.

[0171] The seventh information indicates the sensing resource in 510. For example, the seventh information includes configuration information of the sensing resource.

[0172] Optionally, the seventh information also includes an identifier of the perception task or the perception session.

[0173] 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 carries the configuration of the sensing resource.

[0174] 530. The second network device determines a sensing resource according to the seventh information.

[0175] Optionally, the second network device sends the eighth information to the first network device, and correspondingly, the first network device receives the eighth information. The eighth information indicates that the sensing resource configuration is completed. That is, after completing the sensing resource configuration, the second network device feeds back the configuration completion to the first network device.

[0176] 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 (Xn SetupResponse message) or an NG-RAN node Configuration Update Acknowledge message (NG-RAN node ConfigurationUpdate Acknowledge message).

[0177] 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 perception resource configuration.

[0178] For example, the ninth information includes the identifier of the first network device and the identifier list of the sender. It should be understood that when there is only one sender, the ninth information includes the identifier of the one sender. When there are multiple senders, the ninth information includes the identifiers of the multiple senders.

[0179] 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.

[0180] Optionally, the core network device receives N tenth information, the N tenth information respectively indicating the perception capabilities of N network devices, 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 perception capabilities. For details, please refer to Figure 4 The description about the fourth information and the perception capability in the illustrated embodiment will not be repeated here.

[0181] The core network device determines the first network device as a transmitting end and the second network device as a receiving end according to the sensing capability. The first network device sends a sensing signal to the second network device on the sensing resource.

[0182] Alternatively, the core network device determines the first network device as a receiving end and the second network device as a sending end according to the sensing capability. The second network device sends a sensing signal to the first network device on the sensing resource.

[0183] In the 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, so that the receiving end can accurately receive the perception signal and improve the efficiency of the perception measurement.

[0184] Assume that the first network device and the second network device are responsible for performing the sensing task of the same area. Considering the characteristics of high-frequency signals, the network devices usually use beamforming to send sensing signals. However, in the scenario where network device A sends and network device B receives, if both the sending end and the receiving end use beamforming, it is very likely that the scanning beams of the two will not point to the same area at the same time, resulting in the receiving end being unable to receive the sensing beam sent by the sending end and unable to perform the sensing task.

[0185] In view of this, the embodiment of the present application further proposes a method, which is applicable to a communication system. Figure 6As shown, the method comprises the following steps:

[0186] 610. The core network device sends eleventh information to the first network device. Correspondingly, the first network device receives the eleventh information.

[0187] 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 a perception signal.

[0188] 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.

[0189] 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.

[0190] Specifically, since the receiving network device knows the location of the perception area, the beam of the receiving network device can always be facing the direction of the perception area, and the received perception signal strength is high. For the sending network device, the beam of the sending network device can be configured omnidirectionally. However, at the current moment, only a certain area may need to be perceived, so only the sending network device needs to send the perception beam in several fixed directions. Since the receiving network device does not know the correspondence between the beam configuration and the direction of the sending network device, the receiving network device needs to obtain information about which beam sent by the sending network device it can receive through measurement. The eleventh information can also be used to request the receiving network device (i.e., the first network device) to send: a perception task identifier or a perception session identifier, a list of identifiers of the sending network device (including the second network device) (such as a transmitting base station ID list, transmitting gNB id list), a beam type, a beam number, a frequency deviation, etc. The following steps are all for this perception task or perception session by default.

[0191] 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.

[0192] 620. The first network device measures a sensing beam from the second network device according to the eleventh information.

[0193] In one possible manner, the eleventh information includes a perception session identifier and an identifier of the second network device. The first network device determines that what needs to be reported is a perception beam measurement result of the second network device according to the eleventh information. Then the first network device measures the perception beam from the second network device to obtain the perception beam measurement result.

[0194] In a possible implementation, the first network device sends a beam training request to the second network device, and the second network device receives the beam training request in response. 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.

[0195] 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 to receive. After the beam scanning of the second network device is completed, the first network device records whether the currently used beam 1 can receive the transmitting beam of the second network device. If so, it records information such as the beam type, beam number, and signal strength. Similarly, when the second network device completes the beam scanning, it can be obtained which transmitting beams of the second network device can be received by the first network device 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.

[0196] 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 that can complete beam training are also applicable to the present application.

[0197] 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.

[0198] 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:

[0199] 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.

[0200] The perception beam measurement report is used to report the perception beam measurement results. For example, beam type, beam number, and corresponding frequency band information, frequency offset information, bandwidth information, etc. The beam-related information is used by the second network device to configure the perception signal on the above-mentioned beam. The frequency offset information is used by the second network device to adjust the time domain configuration of transmitting the perception signal, so as to align the receiving time of the first network device.

[0201] 640. The core network device sends the perception beam configuration information to the second network device. Correspondingly, the second network device receives the perception beam configuration information.

[0202] The sensing beam configuration information indicates a sensing beam measurement result.

[0203] Specifically, the core network device may indicate which beam the second network device uses to send the perception signal through the perception beam configuration information. In addition, the second network device may also configure a pattern of the perception signal according to the above-mentioned perception beam measurement result. The pattern is used to indicate the configuration of the perception signal, such as the location of the time domain resource and / or frequency domain resource of the perception signal.

[0204] 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.

[0205] In another possible manner, the first network device may also directly report the measurement result to the second network device without forwarding it through the core network device.

[0206] 650. The first network device sends a perception beam measurement report to the second network device. Correspondingly, the second network device receives the perception beam measurement report.

[0207] The perception beam measurement report is used to report the perception beam measurement result, such as beam type, beam number, and corresponding frequency band information, frequency offset information, bandwidth information, etc. For example, the perception beam measurement report can also be used to request the second network device to update the configuration of the perception signal.

[0208] Optionally, the second network device further sends update completion information to the first network device, and correspondingly, the first network device receives the update completion information. The update completion information is used to indicate that the configuration of the perception signal of the second network device has been updated.

[0209] In this method, by exchanging the configuration information of beams (or perception signals) between N2 or Xn interfaces, it can be ensured that the perception beams of the sending network device and the receiving network device are located in the same perception area, so that the two parties involved in the perception can smoothly perform the perception task. In addition, it can also reduce the waste of resources generated when the sending network device sends beams omnidirectionally.

[0210] It should be understood that the sequence numbers of the above processes do 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.

[0211] 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.

[0212] It should also be understood that in some of the above embodiments, the devices in the existing network architecture are mainly used as examples for exemplary description, and it should be understood that the embodiments of the present application do not limit the specific form of the devices.
