[0002] This application claims priority to Chinese Patent Application No. 202510124343.7, filed on January 24, 2025, entitled "A Communication Method and Communication Device", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of wireless communication technology, and in particular to a communication method and a communication device. Background Technology

[0004] With the rapid development of wireless communication technology, base stations, as core components of networks, are constantly expanding their functions and application scenarios. In recent years, the technology of using base stations for environmental sensing has gradually attracted attention. This technology is based on the interaction between the base station and its surrounding environment, and achieves the perception and monitoring of the surrounding environment by collecting and analyzing the signals received by the base station.

[0005] Sensing services are provided by various specialized sensing devices, such as conventional radar, lidar, computed tomography (CT), and magnetic resonance imaging (MRI). In 5G and earlier communication systems, positioning was the only sensing service that mobile communication systems could provide. In future mobile communication systems, sensing capabilities beyond positioning will be integrated into the communication system to provide entirely new services, such as high-precision positioning, environmental reconstruction, gesture and motion recognition, and vehicle speed measurement.

[0006] However, in the context of integrated communication and sensing, there is currently no solution that proposes how to design the resource configuration of sensing reference signals to reduce the impact on communication. Summary of the Invention

[0007] This application provides a communication method and a communication device for configuring resources for sensing reference signals to reduce the impact of sensing reference signals on communication.

[0008] A first aspect provides a communication method, comprising: a first communication device acquiring configuration information, the configuration information indicating the distribution of N first time-domain resources for sensing a reference signal, each of the N first time-domain resources being used for one sensing measurement, where N is an integer greater than 1; each of the N first time-domain resources including at least two second time-domain resources, the at least two second time-domain resources being located in different time-domain resource units; the distribution satisfying one or more of the following: the time interval between two adjacent first time-domain resources among the N first time-domain resources is a first period; different second time-domain resources within the same first time-domain resource are distributed in the same way within their corresponding time-domain resource units; and the first communication device sending the configuration information to a second communication device. In one possible implementation, the first period is 2.5 milliseconds. In another possible implementation, if the time-domain resource unit is a time slot, and the subcarrier spacing is 30 kHz, the first period can be 5 time slots.

[0009] The first communication device and the second communication device described above are different communication devices. The first communication device may be a communication device (e.g., a network device), or a component of that communication device (e.g., a processor, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the communication device. The second communication device may be a communication device (e.g., a terminal device), or a component of that communication device (e.g., a processor, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the communication device. For example, the first communication device is a network device, and the second communication device is a terminal device.

[0010] In the above method, N first time-domain resources can be configured for the sensing reference signal. Each first time-domain resource is used for one sensing measurement. Each of the N first time-domain resources includes at least two second time-domain resources, which are located in different time-domain resource units. The distribution of the N first time-domain resources of the sensing reference signal satisfies the following conditions: the time interval between two adjacent first time-domain resources is a first period, and / or the distribution of different second time-domain resources within the same first time-domain resource is the same in their corresponding time-domain resource units. After the first communication device obtains the configuration information indicating the distribution of the N first time-domain resources of the sensing reference signal, it sends the configuration information to the second communication device. Subsequently, the first and second communication devices perform measurements through the sensing reference signal based on the configuration information, which can reduce the impact of the sensing reference signal on communication.

[0011] In one possible implementation, the method further includes: a first communication device receiving indication information from a first functional network element, the indication information being used to indicate the configuration of time-domain resources for a sensing reference signal; the first communication device acquiring configuration information, which may include: the first communication device acquiring the configuration information according to the indication information.

[0012] For example, the first functional network element can be a sensing function (SF) network element (hereinafter referred to as SF). The SF can be deployed on the core network or access network equipment side, without restriction. In addition, the SF can be deployed independently or co-located with other network elements. For example, if the SF is co-located with a location management function (LMF) network element (hereinafter referred to as LMF), then the first functional network element can be the LMF.

[0013] In this implementation, the first functional network element instructs the first communication device to configure time-domain resources for the sensing reference signal, so that the first communication device can effectively acquire or generate configuration information of the sensing reference signal when there is a need for sensing measurement.

[0014] In one possible implementation, the configuration information includes multiple bitmap information, each of which indicates the distribution of a second time-domain resource within a corresponding time-domain resource unit. This implementation allows the bitmap information to indicate the distribution of each second time-domain resource within its corresponding time-domain resource unit.

[0015] In one possible implementation, the aforementioned time-domain resource unit is a time slot, and a time slot consists of 14 symbols. Then, the second time-domain resource is two symbols within the time slot; the bitmap information corresponding to these two symbols is 0000 1000 1000 00; or the bitmap information corresponding to these two symbols is 0000 0100 0100 00; or the bitmap information corresponding to these two symbols is 0000 0010 0010 00.

[0016] In one possible implementation, when the first communication device is a central unit (CU), the first communication device acquires configuration information, including: the CU generating configuration information. The first communication device sends configuration information to the second communication device, including: the CU sending the configuration information to the second communication device through a distributed unit (DU) or a radio unit (RU). In this implementation, if the functions of the access network device are implemented by CU, DU, and RU, the CU can generate the configuration information, and then the CU can send the configuration information to the second communication device through the DU or RU.

[0017] For example, if the configuration information is carried in a physical layer message (e.g., downlink control information (DCI)) and sent to the second communication device, the CU sends the configuration information to the DU, and the DU then sends a physical layer message carrying the configuration information to the second communication device. If the configuration information is carried in a higher layer message (e.g., radio resource control (RRC)) and sent to the second communication device, the CU sends the configuration information to the RU, and the RU then sends a higher layer message carrying the configuration information to the second communication device.

[0018] In one possible implementation, when the first communication device is a distributed unit (DU), the first communication device acquires configuration information, including: the DU receiving configuration information from the CU. The first communication device sends configuration information, including: the DU sending configuration information to the terminal device. In this implementation, if the access network device's functions are implemented by a CU, DU, and RU, and the first communication device is a DU, then the DU can obtain configuration information from the CU, and the DU then sends the configuration information to the second communication device.

[0019] In the O-RAN architecture, CU can be replaced with O-CU, DU can be replaced with O-DU, and RU can be replaced with O-RU.

[0020] In a second aspect, a communication method is provided, comprising: a second communication device receiving configuration information from a first communication device, the configuration information indicating the distribution of N first time-domain resources of a sensing reference signal, each of the N first time-domain resources being used for one sensing measurement, where N is an integer greater than 1; each of the N first time-domain resources including at least two second time-domain resources, the at least two second time-domain resources being located in different time-domain resource units; the distribution satisfying one or more of the following: the time interval between two adjacent first time-domain resources among the N first time-domain resources is a first period; different second time-domain resources within the same first time-domain resource are distributed in the same time-domain resource unit; the second communication device performing sensing measurements using the sensing reference signal based on the distribution of the N first time-domain resources. In one possible implementation, the first period is 2.5 milliseconds. In another possible implementation, if the time-domain resource unit is a time slot, with a subcarrier spacing of 30 kHz, the first period can be 5 time slots.

[0021] The first communication device and the second communication device described above are different communication devices. The first communication device may be a communication device (e.g., a network device), or a component of that communication device (e.g., a processor, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the communication device. The second communication device may be a communication device (e.g., a terminal device), or a component of that communication device (e.g., a processor, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the communication device. For example, the first communication device is a network device, and the second communication device is a terminal device.

[0022] In the above method, N first time-domain resources can be configured for the sensing reference signal. Each first time-domain resource is used for one sensing measurement. Each of the N first time-domain resources includes at least two second time-domain resources, which are located in different time-domain resource units. The distribution of the N first time-domain resources of the sensing reference signal satisfies the following conditions: the time interval between two adjacent first time-domain resources is a first period, and / or the distribution of different second time-domain resources within the same first time-domain resource is the same in their corresponding time-domain resource units. After the first communication device obtains the configuration information indicating the distribution of the N first time-domain resources of the sensing reference signal, it sends the configuration information to the second communication device. Subsequently, the first and second communication devices perform measurements through the sensing reference signal based on the configuration information, which can reduce the impact of the sensing reference signal on communication.

[0023] In one possible implementation, the configuration information includes multiple bitmap information, each of which is used to indicate the distribution of a second time-domain resource within a corresponding time-domain resource unit.

[0024] In one possible implementation, the aforementioned time-domain resource unit is a time slot, which consists of 14 symbols. The second time-domain resource is two symbols within the time slot. The bitmap information corresponding to these two symbols is 0000 1000 1000 00; or the bitmap information corresponding to these two symbols is 0000 0100 0100 00; or the bitmap information corresponding to these two symbols is 0000 0010 0010 00.

[0025] In one possible implementation, the second communication device receives configuration information, including: the second communication device receiving the configuration information from a distributed unit (DU) or from a radio frequency unit (RU).

[0026] When the functions of the access network device are implemented by CU, DU and RU, if the first communication device is DU, then the second communication device can receive the configuration information from DU; if the first communication device is RU, then the second communication device can receive the configuration information from RU.

Mobile phone 120j can control drone 120i.

[0061] (1) Network equipment

[0062] A network device is a network-side device with wireless transceiver capabilities. A network device can be a device in a radio access network (RAN) that provides wireless communication capabilities to terminal devices; it can be called an RAN device. The RAN can be an access network in the 3rd Generation Partnership Project (3GPP), such as 4G, 5G, or future networks. The RAN can also be an open RAN (O-RAN or ORAN), a cloud radio access network (CRAN), or a communication network combining two or more of these.

[0063] Network equipment can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation NodeB (gNB) in a 5G mobile communication system, a base station in a future mobile communication system, an access node, transmission node, transceiver node, relay equipment in a WiFi system, or a small or micro station with base station functions, etc.

[0064] Network equipment can also be modules or units that perform some of the functions of a base station. For example, it can be a centralized unit (CU), a distributed unit (DU), or a radio frequency unit (RU). The CU performs the RRC and PDCP functions of the base station and can also perform the service data adaptation protocol (SDAP) functions. The CU can be further divided into a CU control plane (CP) (CU-CP) and a CU user plane (UP) (CU-UP). The DU performs the RLC and MA layer functions of the base station and can also perform some or all of the physical layer functions. For specific descriptions of the above protocol layers, please refer to the relevant 3GPP technical specifications. CU and DU can be set up separately or included in the same network element, such as in a baseband unit (BBU). The RU can be included in radio frequency equipment or radio frequency units, such as in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0065] One possible structure for access network equipment is shown in Figure 2A. In this structure, the core network equipment and access network equipment can communicate via a backhaul link; within the access network equipment, the CU and DU can communicate via a midhaul link, and the DU and RU can communicate via a fronthaul link. Alternatively, another possible structure for access network equipment is shown in Figure 2B, which illustrates an access network equipment implemented using a chip, such as a RAN chip. The RAN chip may include a CU, DU, and RU. The CU can perform L2 and L3 functions, etc.; the DU can perform L1 functions and some L2 functions, etc.; and the RU can perform L1 calculations and radio frequency (RF) digital functions, etc. The CU communicates with the core network equipment via a backhaul interface, which carries the traffic between the CU and the core network equipment. The CU may include a central processing unit (CPU) based on x86 or ARM architecture, as well as field programmable gate arrays (FPGAs), graphics processing units (GPUs), or other accelerators. The CPU can communicate with the FPGA, GPU, or other accelerators via a peripheral component interconnect express (PCIe) interface.

[0066] The CU and DU communicate via a midhaul interface, which carries the traffic between the CU and DU. The DU may include an x86 or ARM architecture CPU, as well as FPGAs, GPUs, or other accelerators, which can communicate with the FPGA, GPU, or other accelerators via a PCIe interface.

[0067] The DU and RU communicate via a fronthaul interface, which carries the traffic between the DU and RU. If the access network equipment uses an integrated DU, the integrated DU can include the functions of both the DU and RU, and the RAN may no longer need to include a separate RU. The RU may include a RAN fronthaul processing unit, a digital processing unit, and an RF processing unit. The RAN fronthaul processing unit is implemented, for example, using an FPGA or an application-specific integrated circuit (ASIC). The digital processing unit is also implemented, for example, using an FPGA or an ASIC. The RU can be connected to an antenna to communicate with the UE via the antenna.

[0068] In different systems, CU, DU, or RU may have different names, but those skilled in the art will understand their meanings. For example, in an ORAN system, CU can also be called O-CU (Open CU), DU can also be called O-DU, and RU can also be called O-RU. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules. The RA device can be a macro base station (as shown in Figure 1, 110a), a micro base station or an indoor station (as shown in Figure 1, 110b), or a relay node or donor node, etc. The embodiments of this application do not limit the specific technology or specific device form used in the network equipment.

[0069] For example, communication between network devices and terminal devices follows a certain protocol layer structure, which may include the Radio Resource Control (RRC) layer, the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, the Media Access Control (MAC) layer, and the Physical Layer (PHY) layer. For detailed descriptions of each of these protocol layers, please refer to the relevant technical specifications of the 3rd Generation Partnership Project (3GPP).

[0070] Figure 3 illustrates a schematic diagram of a network device architecture. As shown in Figure 3, the network device includes one or more functional modules for signal processing. Taking the physical layer function as an example, the network device can perform one or more of the following functions: coding, rate matching, scrambling, modulation, layer mapping, precoding, resource element (RE) mapping, digital beamforming (BF), inverse fast fourier transformation (IFFT) / adding a cyclic prefix (CP), decoding, rate matching dematching, descrambling, demodulation, inverse discrete fourier transformation (IDFT), channel equalization (or channel estimation), RE demapping, digital BF, fast fourier transform (FFT) / CP removal, digital to analog (DA) conversion, analog BF, analog to digital (AD) conversion, or analog BF.

[0071] In Figure 3, CPRI stands for Common Public Radio Interface, used to connect the building base band unit (BBU) and radio remote unit (RRU) of a wireless base station. eCPRI stands for Enhanced Common Public Radio Interface. eCPRI Cat A to F are several categories divided to meet different needs. These categories differ in key performance indicators such as data transmission rate, latency, and functional support to accurately adapt to various service scenarios, from simple mobile Internet access to complex industrial control and high-bandwidth multimedia transmission.

[0072] (2) Terminal equipment

[0073] A terminal device is a user-side device with wireless transceiver capabilities. Terminal devices can also be called terminals, user equipment (UE), mobile stations, mobile terminals, etc. Terminal devices can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communications (MTC), the Internet of Things (IoT), the Industrial Internet, virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, and smart cities. Terminal devices can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, vehicles, drones, helicopters, airplanes, ships, robots, robotic arms, smart home devices, etc. In the embodiments of this application, the device used to implement the functions of the terminal device can be the terminal device itself, or it can be a device that supports the terminal device in implementing that function, such as a chip system or a combination of devices or components that can implement the functions of the terminal device. This device can be installed in the terminal device. The embodiments of this application do not limit the specific technology or specific device form used in the terminal device.

[0074] For example, the terminal device includes one or more functional modules for signal processing. For instance, the terminal device can perform one or more of the following functions: encoding, decoding, rate matching, rate dematching, scrambling, descrambling, modulation, demodulation, layer mapping, FFT, IFFT, IDFT, precoding, RE mapping, channel equalization, RE mapping, digital BF, adding CP, removing CP, etc.

[0075] Network devices and terminal devices can be fixed in location or mobile. They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can also be deployed in the air on airplanes, balloons, and artificial satellites. The embodiments of this application do not limit the application scenarios of the network devices and terminal devices.

[0076] The roles of network devices and terminal devices can be relative. For example, the helicopter or drone 120i in Figure 1 can be configured as a mobile network device. For terminal devices 120j that access the wireless access network 100 via 120i, terminal device 120i is a network device; however, for network device 110a, 120i is a terminal device. That is, 110a and 120i communicate via a wireless air interface protocol. Of course, 110a and 120i can also communicate via a network device-to-network device interface protocol. In this case, relative to 110a, 120i is also a network device. Therefore, both network devices and terminal devices can be collectively referred to as communication devices. 110a and 110b in Figure 1 can be called communication devices with network device functions, and 120a-120j in Figure 1 can be called communication devices with terminal device functions.

[0077] Network devices and terminal devices, network devices and network devices, and terminal devices and terminal devices can communicate through licensed spectrum, unlicensed spectrum, or both licensed and unlicensed spectrum simultaneously; there are no specific limitations.

[0078] The embodiments of this application are applicable to communication and / or sensing networks. Referring to Figure 4A, which is a schematic diagram of a potential sensing network architecture based on a 5G core network (5G core, 5GC), the network architecture shown in Figure 4A can also be an application scenario of the embodiments of this application.

[0079] In the architecture shown in Figure 4A, a new sensing function (SF) network element has been added, which can also be simply referred to as the sensing network element. This SF can be a device or component that provides sensing functionality to the network; it can also be called a sensing management function (SMF), or have other names. This SF can be deployed on the core network side or the RAN side; Figure 4A shows an example of deployment in the core network. In the network architecture shown in Figure 4A, the SF can reuse the interfaces between the LMF and AMF, network exposure function (NEF), unified data management (UDM), network data analytics function (NWDAF), PCF, and other 5GC network elements for sensing interaction. Sensing signaling between the SF and the radio access network (RAN) or UE can be transmitted through the AMF; sensing measurement data acquired by the RAN or UE can be transmitted to the SF via the control plane, for example, by using the reused long term evolution (LTE) positioning protocol (LPP) or new radio (NR) positioning protocol annex (NRPPa) protocol, or it can be transmitted through the user plane, forwarded to the SF via the UPF, or directly transmitted to the SF.

[0080] The newly added SF in this network architecture can realize basic sensing functions, such as sensing authorization, sensing control, sensing measurement data processing, or result output. Specifically, interfaces are set up and interaction is established between the SF and 5GC network elements such as AMF, NEF, UDM, NWDAF, PCF, LMF, and UPF, as defined below.

[0081] NS1: A new interface between SF and AMF, which can transmit sensing and control signaling. Additionally, this interface can also transmit sensing measurement data in scenarios where sensing measurement data is uploaded to the control plane.

[0082] NS2: A new interface between SF and NEF. This interface can transmit signaling messages between sensing network elements relayed through NEF and application functions (AF) on the service side, and at the same time open the sensing results to the AF.

[0083] NS3: A new interface between SF and UDM. This interface can be used for authentication or authorization, and to obtain UE-aware subscription information, service AMF information, or other information.

[0084] NS4: A new interface between SF and NWDAF. Through this interface, SF and NWDAF can jointly complete artificial intelligence (AI) processing related to perception services.

[0085] NS5: A new interface between SF and PCF. Through this interface, SF can transmit information such as sensing requirements, quality of service (QoS) requirements, or sensing results of sensing services to PCF. PCF can then make decisions to generate policy control and charging (PCC) policies related to sensing services.

[0086] NS6: A new interface between SF and LMF. Through this interface, SF can obtain location-related information, such as the sensing area, the RAN information of the sensing target, and the location information of the sensed UE.

[0087] NS7: A new interface between SF and UPF. Sensing measurement data can be directly transmitted from (R)AN to SF via UPF, or indirectly forwarded to SF via UPF. In scenarios where (R)AN performs sensing, forwarding via UPF can improve the functionality of UPF to support data transmission at the (R)AN granularity.

[0088] In addition to the newly added interfaces mentioned above, existing interfaces (such as N1, N2, N5, N8, N33, etc.) can also support the transmission of information related to sensing services, such as authentication information, sensing service type, sensing service quality requirements, sensing measurement data, or sensing results, etc.

[0089] Figure 4A illustrates an example where the SF (Sensitive Detection) is a standalone device. Alternatively, the SF and LMF (Local Positioning Detector) can be co-located, meaning the network element handling sensing services and the network element handling location services can be the same. Alternatively, the SF can be co-located with other core network elements, such as the AMF (Auxiliary Positioning Detector). The LMF is the core network element in the 5GC that provides control plane positioning. It can calculate and feedback location information in the 5G network, providing functions such as positioning process management, UE capability acquisition, auxiliary data provision, and UE location estimation. Optionally, if the SF and LMF are co-located, the LMF and the gateway mobile location center (GMLC) can be functionally enhanced to support basic sensing functions. The GMLC can be the first network element within the operator's network to process sensing requests, performing privacy checks or authorization functions, routing sensing requests to the AMF, or performing LMF selection, etc.

[0090] For example, if the SF and LMF are co-located, an additional interface can be added between the LMF and GMLC to transmit information related to awareness services, such as adding an NL9 interface. Additionally, interfaces related to the LMF and GMLC (such as one or more of the following: NL1 interface between AMF and LMF, NL2 interface between AMF and GMLC, NL5 interface between NEF and GMLC, or NL6 interface between UDM and GMLC) can also support the transmission of information related to awareness services, as detailed below.

[0091] N33: The interface between AF and NEF, through which information such as the type of sensing business, business requirements, and sensing results can be transmitted.

[0092] NL5: The interface between NEF and GMLC, through which information such as the type of sensing business, business requirements, and sensing results can be transmitted.

[0093] NL6: The interface between GMLC and UDM, through which privacy inspection data can be transmitted.

[0094] NL2: The interface between NEF and AMF, through which information such as the perceived business type, business requirements, and perceived results can be transmitted.

[0095] NL1: The interface between AMF and LMF, through which information such as perceived business type, business requirements, and perceived results can be transmitted.

[0096] NL9: A new interface between GMLC and LMF, through which information such as the type of sensing business, business requirements, and sensing results can be transmitted.

[0097] Referring again to Figure 4B, which is a schematic diagram of another potential sensing network architecture based on 5GC, the network architecture shown in Figure 4B can also be another application scenario of the embodiments of this application.

[0098] In the network architecture shown in Figure 4B, the SF (Sensitive Detection) is relatively independent of the existing core network elements. The SF requires little or no interaction with the core network elements. For scenarios where sensing needs exist only in a specific area, this network architecture can provide sensing services without requiring 5GC control or only requiring some network elements to participate in control. Furthermore, localized deployment of the SF ensures that sensing measurement data or results do not leave the campus, thus meeting enterprises' needs for the security and privacy of sensing measurement data or results, and reducing sensing latency. This network architecture is relatively simple, flexible, efficient, has few transmission nodes, and is easy to deploy. Optionally, this network architecture can support UE-related sensing needs, and implementation schemes for functions such as authorization, mobility management, and billing can be considered as needed.

[0099] In this network architecture, the SF can directly establish a connection with the RAN node. Control plane sensing signaling and user plane sensing measurement data can be transmitted via the newly defined interface NS1. When the UE participates in sensing, control plane signaling can be forwarded to the SF via the AMF, and sensing measurement data can be transmitted via NS1. Furthermore, there can also be an interface between the SF and 5GC network elements (such as AMF, NEF, or NWDAF) to control the AF to provide sensing service requirements to the SF through core network functions. The interface between the SF and 5GC network elements is described below.

[0100] NS1: A new interface between the SF and (R)AN, which can transmit sensing control signaling or sensing measurement data. In one implementation, the SF can also be deployed on the RAN side; for example, the SF can be co-located with access network equipment (e.g., a base station), or the SF can be a standalone device within the access network.

[0101] NS2: A new interface that may be added between SF and AMF. This interface can receive awareness service requirements from UE, or transmit signaling between SF and other network elements in the core network, such as transmitting interaction messages between SF and UDM.

[0102] NS3: A potential new interface between SF and NEF. This interface can transmit signaling between SF and the service-side AF via NEF, and can also expose the sensing results to the AF. The interaction between SF and AF may not go through NEF. In actual deployment, NS2 and NS3 may be chosen as one of the two options. That is, the AF can send sensing service requests indirectly to SF or directly to SF (without NEF) via NS2 (NEF); or, the AF can send sensing service requests to SF via N33 (NEF) and NS2 (AMF).

[0103] NS4: A potential new interface between SF and NWDAF, through which SF and NWDAF can jointly perform intelligent analysis and prediction to generate perception results.

[0104] Figures 4A and 4B above are based on 5GC. In addition, SF can also be deployed in other networks or future communication networks. The embodiments of this application can be applied to the scenarios shown in Figure 1, Figure 4A, or Figure 4B, or other scenarios, such as any scenario involving sensing services.

[0105] The network architecture and business scenarios described in this application are intended to more clearly illustrate the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0106] The following is an explanation of the relevant terms used in the embodiments of this application. Unless otherwise specified, these explanations are provided to support the meaning of the relevant terms and to make the embodiments of this application easier to understand, and should not be regarded as a strict limitation of the relevant terms within the scope of protection claimed by this application.

[0107] (1) Sensing reference signal:

[0108] In this embodiment, the signal used to implement sensing functions or sensing services is referred to as a sensing reference signal. The sensing reference signal is transmitted through reflection, scattering, or diffraction. The sensing device (e.g., a network device) can determine relevant characteristics of the sensing target based on the received sensing reference signal. For example, it can estimate time delay, Doppler, or angular spectrum information based on the received sensing reference signal to determine information such as the distance, angle, or velocity of the sensing target. Additionally, the network device can also send measurement results, such as point cloud information, distance, angle, or velocity information of the sensing target, to the sensing network element (e.g., SF or LMF).

[0109] In the embodiments of this application, the sensing reference signal may also have other commands, such as a first reference signal or a sensing signal.

[0110] (2) Time-domain resources:

[0111] Time-domain resources refer to the resources available in the time domain in a wireless communication system. For example, in 5G communication, time-domain resources can include concepts such as frames, subframes, time slots, and symbols, which can be used to transmit data and signals.

[0112] For example, the base station allocating corresponding time-domain resources to UE1 can be understood as the base station allocating available resources such as frames, subframes, time slots, or symbols to UE1. For instance, if the base station allocates symbols 4 and 8 in time slot 1 and symbols 4 and 8 in time slot 2 of the sensing reference signal to UE1, then the base station and UE1 will perform measurements on symbols 4 and 8 in time slot 1 and symbols 4 and 8 in time slot 2 using the sensing reference signal.

[0113] (3) Frequency domain resources:

[0114] Frequency domain resources refer to the resources within the frequency range used for data transmission in a wireless communication system.

[0115] Typically, frequency domain resources can include subcarriers (SC), resource blocks (RB), resource block groups (TBG), resource elements (RE), etc. These resources are allocated and managed in the frequency domain for transmitting data and control signals, etc.

[0116] It should be noted that in the embodiments of this application, "at least one" refers to one or more, and "more than one" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can represent: a, b, c, a and b, a and c, b and c, or a and b and c, where a, b, and c can be single or multiple.

[0117] Furthermore, unless otherwise stated, the ordinal numbers such as "first," "second," or "1," "2," etc. (except in special cases indicating numerical values) mentioned in the embodiments of this application are used to distinguish multiple objects and are not used to limit the size, content, order, timing, priority, or importance of the multiple objects. For example, "first communication device" and "second communication device" are only used to distinguish different communication devices and do not indicate that the two communication devices are different in size, priority, or importance.

[0118] It should be noted that in this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner. In the embodiments of this application, "of," "relevant," and "corresponding" may sometimes be used interchangeably, and it should be pointed out that their intended meanings are consistent unless their distinction is emphasized.

[0119] The terms "comprising" and "having," and any variations thereof, used in the following description of embodiments of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include other steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices. Furthermore, the term "for indicating" used in the description of embodiments of this application can include both direct and indirect indication. When describing an indication message for indicating A, it may include whether the indication message directly indicates A or indirectly indicates A, but does not necessarily mean that the indication message carries A.

[0120] The following describes the application scenarios, technical problems, and solutions involved in the embodiments of this application.

[0121] For a long time, wireless sensing has been an independently developed technology with little overlap with the development of mobile communication systems. Sensing services are provided by various specialized sensing devices, such as conventional radar, lidar, computed tomography (CT), and magnetic resonance imaging (MRI). In 5G and earlier communication systems, positioning was the only sensing service that mobile communication systems could provide. In future mobile communication systems, general sensing beyond positioning will be integrated into the communication system as a completely new function, thereby opening up entirely new services, such as high-precision positioning, environmental reconstruction, and gesture and motion recognition.

[0122] For example, the environment of the target area can be reconstructed by means of laser, radar, base station, etc., that is, the real physical environment can be perceived and reconstructed. For example, the environment between the UE and the base station can be reconstructed based on measurement information using methods such as scattering polygons, and the scattering objects such as walls and furniture in the area can be depicted.

[0123] For vehicle perception, it is necessary to sense the vehicle's speed. Currently, radar speed measurement works by utilizing the Doppler effect, calculating speed by analyzing the Doppler information carried in the target's echo. Radar emits electromagnetic waves, and when these waves encounter a moving object, the frequency of the reflected wave changes (Doppler shift). By detecting this frequency change, the object's speed can be calculated.

[0124] Doppler effect-based speed measurement at base stations: Utilizing the Doppler effect, the frequency of the wireless signal reflected by a vehicle changes as it passes a base station. By measuring this frequency change, the vehicle's speed can be calculated. In base station speed measurement, the frequency of the reflected electromagnetic waves increases as the vehicle approaches the base station, and decreases as the vehicle moves away. This is because when the vehicle approaches the base station, the reflected electromagnetic waves are compressed during propagation, resulting in a shorter wavelength and a higher frequency; conversely, when the vehicle moves away from the base station, the electromagnetic waves are stretched, resulting in a longer wavelength and a lower frequency.

[0125] By measuring this frequency change, known as the Doppler shift, the base station can calculate the relative speed between the vehicle and the base station. Specifically, the degree of the Doppler shift is proportional to the relative speed between the wave source and the observer.

[0126] The following explains the principle of base station speed measurement based on the Doppler effect:

[0127] Doppler shift: If the target does not move, as shown in Figure 5A: assuming the transmitted signal from the source to the target can be expressed as: x s (t)=A tsin(2πf t t); where x s (t) represents the transmitted signal, f t For the transmission frequency, A t Let x be the amplitude of the transmitted signal. Considering the flight time τ of the reflected signal from the transmission to the reception of the echo signal, the reflected signal can be expressed as follows: x r (t)=A r sin(2πf r t+φ)=A r sin(2πf t (t-τ));

[0128] Where, x r (t) represents the reflected signal, f r R is the reflection frequency, R0 is the distance between the source and the target, and A is the distance between the source and the target. r Given the amplitude of the received signal, the phase difference between the transmitted and reflected signals can be calculated as follows: Δφ is the phase difference between the transmitted and reflected signals, and λ is the wavelength.

[0129] Given that the initial distance between the transmitter and the target is R0, if the transmitter and the target are in relative motion, as shown in Figure 5B: the propagation delay from the emission of the transmitted signal to the receipt of the echo signal after reflection is: Let τ be the transmission delay and c be the wave speed. Then the reflected signal can be expressed as follows:

[0130] By comparing the transmitted and reflected signals, the frequency difference Δf can be obtained, which is the Doppler frequency, as shown below:

[0131] f s This refers to the transmitting frequency.

[0132] Speed ​​measurement principle:

[0133] Referring to Figure 5C, two transmitters are launched with a spacing of T. c The signal is analyzed by measuring the phase difference Δφ between the peak values ​​of the two signals. This phase difference Δφ corresponds to the motion of the object. Assuming the object's velocity is v, then the object's motion during the time interval T... c The distance moved within is vT c Then the phase difference Δφ is expressed as: Therefore, the velocity v can be obtained as:

[0134] However, in the context of integrated communication and sensing, there is currently no solution that proposes how to design the resource configuration of sensing reference signals to reduce the impact on communication.

[0135] To address the aforementioned problems, this application proposes a communication method and a communication device for configuring resources for sensing reference signals, thereby reducing the impact of sensing reference signals on communication. The communication method and communication device are based on the same inventive concept. Since the principles underlying the problems solved by the communication method and communication device are similar, their implementations can be mutually referenced, and repeated details will not be elaborated further.

[0136] The technical solution of this application is described below with reference to specific embodiments.

[0137] This application provides a communication method applicable to, but not limited to, the communication system shown in Figure 1 (or the network architecture shown in Figure 4A or Figure 4B). The method can be implemented by a first communication device and a second communication device. The first communication device can act as a transmitter and / or a receiver, and the second communication device can also act as a transmitter and / or a receiver. For example, if the first communication device is the transmitter, then the second communication device is the receiver; or if the first communication device is the receiver, then the second communication device is the transmitter. The following example uses the first communication device as the transmitter and the second communication device as the receiver. The first and second communication devices are different communication devices. The first communication device can be a communication device (e.g., a network device), or a component within that communication device (e.g., a processor, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the communication device. The second communication device can be a communication device (e.g., a terminal device), or a component within that communication device (e.g., a processor, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the communication device. For example, the first communication device is a network device, and the second communication device is a terminal device.

[0138] This application does not impose specific limitations on the specific structure of the execution entities (such as the first communication device and the second communication device) or the number of each execution entity in the methods provided in the embodiments of this application. As long as communication can be performed according to the methods provided in the embodiments of this application by running a program that records the code of the methods provided in the embodiments of this application, the following description uses the interaction between the first communication device and the second communication device as an example. Referring to Figure 6, the flow of the method provided in the embodiments of this application includes the following steps:

[0139] S601: The first communication device obtains configuration information.

[0140] The configuration information indicates the distribution of N first time-domain resources for sensing the reference signal. Each of the N first time-domain resources is used for one sensing measurement, and N is an integer greater than 1. Each of the N first time-domain resources includes at least two second time-domain resources, which are located in different time-domain resource units. The distribution satisfies one or more of the following:

[0141] (1) The time interval between two adjacent first time domain resources in N first time domain resources is the first period.

[0142] In one possible implementation, the first period is 2.5 milliseconds (ms).

[0143] In another possible implementation, if the time-domain resource unit is a time slot, and the subcarrier spacing is 30kHz, the first period can be 5 time slots.

[0144] (2) Different second time-domain resources within the same first time-domain resource have the same distribution within the corresponding time-domain resource unit.

[0145] In one possible implementation, the configuration information includes multiple bitmap information, each of which is used to indicate the distribution of a second time-domain resource within a corresponding time-domain resource unit.

[0146] For example, if the aforementioned time-domain resource unit is a time slot, and a time slot consists of 14 symbols, then the second time-domain resource is two symbols within one time slot. In the configuration information, the bitmap information corresponding to these two symbols is 0000 1000 1000 00; or the bitmap information corresponding to these two symbols is 0000 0100 0100 00; or the bitmap information corresponding to these two symbols is 0000 0010 0010 00.

[0147] In one possible implementation, the method of this application embodiment further includes: a first communication device receiving indication information from a first functional network element, the indication information being used to indicate the configuration of time-domain resources for a sensing reference signal; then the first communication device generating configuration information includes: the first communication device generating the aforementioned configuration information according to the indication information. Optionally, this implementation can be performed before S601.

[0148] For example, the first functional network element can be the sensing function (SF), which can be deployed on the core network or access network equipment side without restriction. In addition, the SF can be deployed independently or co-located with other network elements. For example, if the SF is co-located with the positioning management function (LMF), then the first functional network element can be the LMF.

[0149] S602: The first communication device sends configuration information to the second communication device, and correspondingly, the second communication device receives the configuration information from the first communication device.

[0150] In this embodiment of the application, the functions of the network device (or access network device) are implemented by a unit comprising a CU, a DU, and a RU. In one possible implementation, where the first communication device is a CU:

[0151] The first communication device acquires configuration information, including: generating the configuration information by the CU.

[0152] The first communication device sends configuration information to the second communication device, including: sending the configuration information to the second communication device via a DU, and correspondingly, the second communication device receiving the configuration information from the DU; or sending the configuration information to the second communication device via a RU, and correspondingly, the second communication device receiving the configuration information from the RU.

[0153] In another possible implementation, where the first communication device is a DU:

[0154] The first communication device acquires configuration information, including: the DU receiving the configuration information from the CU.

[0155] The first communication device sends configuration information to the second communication device, including: the DU sending the configuration information to the second communication device, and correspondingly, the second communication device receiving the configuration information from the DU.

[0156] S603: Based on the configuration information, the second communication device performs sensing measurements with the second communication device via a sensing reference signal.

[0157] In this embodiment, the second communication device performs sensing and measurement based on the distribution of N first time-domain resources and sensing reference signals, which can be used to achieve speed measurement, high-precision positioning, etc.

[0158] In the above method, N first time-domain resources can be configured for the sensing reference signal. Each first time-domain resource is used for one sensing measurement. Each of the N first time-domain resources includes at least two second time-domain resources, which are located in different time-domain resource units. The distribution of the N first time-domain resources of the sensing reference signal satisfies the following conditions: the time interval between two adjacent first time-domain resources is a first period, and / or the distribution of different second time-domain resources within the same first time-domain resource is the same in their corresponding time-domain resource units. After the first communication device obtains the configuration information indicating the distribution of the N first time-domain resources of the sensing reference signal, it sends the configuration information to the second communication device. Subsequently, the first and second communication devices perform measurements through the sensing reference signal based on the configuration information, which can reduce the impact of the sensing reference signal on communication.

[0159] Based on the scheme shown in Figure 6 above, the scheme of the embodiments of this application will be described in detail below through specific implementation methods.

[0160] Implementation Method 1:

[0161] In Implementation Method 1, taking the first communication device as an access network device (hereinafter referred to as RAN1, where RAN1 represents a certain access network device) and the second communication device as a terminal device (hereinafter referred to as UE1, where UE1 represents a certain terminal device) as an example, the scheme shown in Figure 6 is applied to the following process, and the scheme shown in Figure 6 is described in detail. Referring to Figure 7, the method flow of Implementation Method 1 includes the following steps:

[0162] S701: UE1, RAN1, and SF transmit perception configuration information.

[0163] S702: SF sends a sensing information request to RAN1, and RAN1 receives the sensing information request accordingly.

[0164] S703: RAN1 sends a sensing information response to SF, and SF receives the sensing information response accordingly.

[0165] S704: RAN1 and SF send perception information requests to UE1 respectively, and UE1 receives perception information requests from RAN1 and SF respectively.

[0166] Among them, the perception information request can be used to request and obtain perception information.

[0167] S705: UE1 sends perception information responses to RAN1 and SF respectively, and RAN1 and SF respectively receive perception information responses from UE1.

[0168] Among them, the sensing information response can be used to indicate that sensing information has been successfully received.

[0169] S706: SF sends a sensing measurement request to RAN1, and RAN1 receives the sensing measurement request accordingly.

[0170] One possible implementation is that the perception measurement request is used to request the execution of perception measurements and / or the generation of perception configuration information.

[0171] The specific implementations of S701 to S706 can be referenced or consulted with existing perception-related technologies, and will not be elaborated here.

[0172] S707: RAN generates sensing configuration information (example of configuration information in the scheme shown in Figure 6 above).

[0173] The sensing configuration information is used to indicate the pilot pattern of the sensing reference signal, or the sensing configuration information includes the pilot pattern of the sensing reference signal.

[0174] For example, in Implementation Method 1, the pilot pattern of the sensing reference signal (hereinafter referred to as ISAC RS) is designed based on the pilot pattern of the tracking reference signal TRS, with a pulse period of 2.5ms, as follows:

[0175] Figure 8 shows two pilot patterns corresponding to ISAC RS. In pattern 1 shown in Figure 8 (1) and pattern 2 shown in Figure 8 (2), the time interval between two adjacent pulses (the time interval / first period example between two adjacent first time domain resources in the scheme shown in Figure 6 above) is 2.5ms.

[0176] The difference between Pattern 1 shown in Figure 8(1) and Pattern 2 shown in Figure 8(2) is that the number of symbols corresponding to each pulse signal is different. Specifically, the time domain resources corresponding to Pattern 1 shown in Figure 8(1) are used for two measurements of the reference signal. These two measurements of the reference signal can be two ISAC RS measurements, or one ISAC RS measurement and one TRS measurement. There is no restriction on this. Each measurement of the reference signal occupies two symbols in two time slots, that is, it occupies two symbols in each of the two time slots.

[0177] The time-domain resources corresponding to pattern 2 shown in Figure 8 (2) are used for two reference signal measurements. These two reference signal measurements can be either two ISAC RS measurements or one ISAC RS measurement and one TRS measurement. There is no restriction on this. Each reference signal measurement occupies two symbols in one time slot.

[0178] If a time slot contains 14 symbols, the indices of these 14 symbols are 0, 1, 2, 3, 4, 5, 6, 7, ..., 13, and the index of each symbol is used to determine the position of the symbol within the time slot. In one possible implementation, based on pattern 1 shown in Figure 8 (1), each measurement of the reference signal occupies 2 symbols in one time slot, and the indices of these 2 symbols can be any of the following:

[0179] (1) 4 and 8;

[0180] For example, the symbols with indices 4 and 8 within a time slot are represented as symbol 4 and symbol 8.

[0181] (2) 5 and 9;

[0182] For example, the symbols with indices 5 and 9 within a time slot are represented as symbol 5 and symbol 9.

[0183] (3) 6 and 10;

[0184] For example, the symbols with indices 6 and 10 within a time slot are represented as symbol 6 and symbol 10.

[0185] For example, taking each ISAC RS measurement as occupying two symbols in two time slots, the indices of the two symbols in each time slot are 4 and 8. Figure 9 exemplarily shows the patterns of the two time slots (time slot 5 and time slot 6) corresponding to one ISAC RS measurement. Referring to Figure 9, in the ISAC RS pattern corresponding to time slot 5, the two symbols corresponding to ISAC RS are symbol 4 (i.e., the 5th symbol in time slot 5) and symbol 8 (i.e., the 9th symbol in time slot 5); in the ISAC RS pattern corresponding to time slot 6, the two symbols corresponding to ISAC RS are symbol 4 (i.e., the 5th symbol in time slot 6) and symbol 8 (i.e., the 9th symbol in time slot 6).

[0186] In one possible implementation, the ISAC RS pattern corresponding to time slot 5 in Figure 9 is the same as the ISAC RS pattern corresponding to time slot 6. Taking the pattern of time slot 5 as an example, time slot 5 corresponds to 12 subcarriers in the frequency domain, represented as subcarrier 0, subcarrier 1, subcarrier 2, ..., subcarrier 11. The ISAC RS occupies symbol 4 in the time domain and subcarriers 0, 4, and 8 in the frequency domain, or it can occupy all subcarriers in the frequency domain. The ISAC RS occupies symbol 8 in the time domain and subcarriers 0, 4, and 8 in the frequency domain, or it can occupy all subcarriers in the frequency domain.

[0187] Based on the above ISAC RS pattern, assuming the total number of configurable time slots is 40, the uplink / downlink time slot ratio can be 3:7 or DDDSUDSUU. Taking a downlink time slot ratio of 3:7 as an example, Figure 10 shows the ISAC RS pattern to indicate the position of the time slot resource corresponding to the ISAC RS in the total time slot resources.

[0188] In the diagram shown in Figure 10, using ISAC RS and TRS as examples of reference signals, each measurement of the reference signal occupies two symbols in two time slots, and the time interval between two adjacent measurements of the reference signal is five time slots. Specifically, the first ISAC RS measurement corresponds to symbols 4 and 8 in time slot 0, and symbols 4 and 8 in time slot 1. The second TRS measurement corresponds to symbols 4 and 8 in time slot 5, and symbols 4 and 8 in time slot 6. The third ISAC RS measurement corresponds to symbols 4 and 8 in time slot 10, and symbols 4 and 8 in time slot 11.

[0193] Example 1: Based on the pattern shown in Figure 8 (1) above, each ISAC RS measurement occupies 2 symbols in 2 time slots. The indices of the 2 symbols in each time slot are 4 and 8. Then the bitmap corresponding to these 2 time slots is: 0000 1000 1000 00 0000 1000 1000 00. The interval between adjacent ISAC RS measurements is 5 time slot periods.

[0199] S709: RAN1 and UE1 perform sensing measurements based on sensing configuration information and sensing reference signals to obtain sensing measurement results.

[0200] The above S707 to S709 can be examples of S601 to S603 in the scheme shown in Figure 6.

[0201] S710: RAN1 sends the sensing measurement results to SF, and SF receives the sensing measurement results accordingly.

[0202] In one possible implementation, SF uses the sensing measurement results to achieve sensing speed measurement. The specific calculation or principle of sensing speed measurement can be found in Figures 5A to 5C above, and will not be repeated here.

[0203] In one possible implementation, SF can be replaced with LMF in the above steps, that is, LMF can perform the steps performed by SF in S701 to S706 and S710.

[0204] In Implementation Method 1, the pilot signal of the sensing reference signal can be designed based on the pilot signal of the TRS. This allows sensing measurement (e.g., sensing speed measurement) to be achieved without modifying the communication reference signal, thereby effectively reducing the impact of the sensing reference signal on communication.

[0205] Implementation Method Two:

[0206] In Implementation Method 1, the access network device (hereinafter referred to as RAN1) is implemented by including CU1, DU1, and RU1, and the second communication device is a terminal device (hereinafter referred to as UE1). As an example, the scheme shown in Figure 6 is applied to the following process, and the scheme shown in Figure 6 is described in detail. Referring to Figure 11, the method flow of Implementation Method 2 includes the following steps:

[0207] S1101: UE1 transmits perception configuration information with RU1, DU1, CU1 and SF.

[0208] S1102: SF sends a sensing information request to RU1, and RU1 receives the sensing information request accordingly.

[0209] S1103: RU1 sends a sensing information response to SF, and SF receives the sensing information response accordingly.

[0210] S1104: CU1 and SF send perception information requests to UE1 respectively, and UE1 receives perception information requests from CU1 and SF respectively.

[0211] S1105: UE1 sends perception information responses to CU1 and SF respectively, and CU1 and SF respectively receive perception information responses from UE1.

[0212] S1106: SF sends a sensing measurement request to RU1 and UE1 respectively, and RU1 and UE1 respectively receive the sensing measurement request.

[0213] One possible implementation is that the perception measurement request is used to request the execution of perception measurements and / or the generation of perception configuration information.

[0214] In one possible implementation, RU1 sends the sensing measurement request to CU1, or sends an instruction message to instruct CU1 to generate sensing configuration information.

[0215] S1107: CU1 generates perception configuration information.

[0216] The sensing configuration information is used to indicate the pilot pattern of the sensing reference signal, or the sensing configuration information includes the pilot pattern of the sensing reference signal.

[0217] The specific content of the perception configuration information in S1107 can be found in the relevant introduction of the perception configuration information in S707 mentioned above, and will not be repeated here.

[0218] S1108: RU1 sends an RRC message to UE1, and UE1 receives the RRC message accordingly.

[0219] The RRC message includes the aforementioned perception configuration information.

[0220] In this embodiment, before RU1 sends an RRC message to UE1, CU1 sends perception configuration information to RU1, and RU1 receives the perception configuration information accordingly.

[0221] In one possible implementation, if CU1 sends the perception configuration information to UE1 via physical layer signaling or a message, then in S1108, DU1 can send a message carrying the perception configuration information to UE1.

[0222] The RRC message carrying perception configuration information in S1108 can be referred to the relevant introduction of the RRC message carrying perception configuration information in S708 above, and will not be repeated here.

[0223] S1109: DU1, RU1, CU1 and UE1 perform perception measurements with perception reference signals based on perception configuration information to obtain perception measurement results.

[0224] In one possible implementation, after DU1 obtains the sensing measurement result, it sends the sensing measurement result to CU1, which then sends it to RU1. Alternatively, after DU1 obtains the sensing measurement result, it sends the sensing measurement result to RU1.

[0225] S1110: RU1 sends the sensing measurement result to SF, and SF receives the sensing measurement result accordingly.

[0226] In one possible implementation, SF can be replaced with LMF in the above steps, that is, LMF can perform the steps performed by SF in S1101 to S1106 and S1110.

[0227] In the above, DU1 and RU1 may or may not be co-located.
