Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a sensing method and apparatus. Background Technology

[0002] Current communication-sensing fusion technologies primarily rely on superimposing sensing capabilities onto existing communication networks to achieve a unified integration of sensing and communication. This integration mainly manifests in aspects such as waveform, spectrum, and antenna. Specifically, the spectrum integration of sensing and communication involves transmitting sensing signals over communication resources or bandwidth.

[0003] Currently, sensing signals are transmitted over communication resources, but the bandwidth requirements of sensing services and communication services are usually different. For example, for communication services, some terminal devices do not require high-speed data transmission. To reduce power consumption, these terminal devices have lower hardware and software complexity and support smaller communication bandwidths. However, for sensing services, sensing accuracy depends on bandwidth; the greater the bandwidth, the higher the sensing accuracy. Therefore, sensing services have higher bandwidth requirements. It is evident that the bandwidth requirements of sensing services and communication services are contradictory, and current communication resources may not be able to simultaneously meet the needs of both sensing and communication services. Summary of the Invention

[0004] This application provides a sensing method and apparatus to resolve the contradiction between the bandwidth requirements of sensing services and communication services.

[0005] Firstly, a first sensing method is provided, which can be applied to a first device. Optionally, the first device is a terminal-side device, also referred to as a terminal device. This terminal device is, for example, a terminal equipment, or other equipment including terminal equipment functions, or a circuit, or a system-on-a-chip (or, a chip, such as a modem chip, also known as a baseband chip, or a system-on-a-chip (SoC) chip containing a modem core, or a system-in-package (SIP) chip) or other functional module, which can implement the functions of the terminal equipment, and is, for example, disposed in the terminal equipment. The method includes: transmitting or receiving a first sensing signal on a first frequency domain resource, the first sensing signal being used for sensing, wherein the first frequency domain resource is used by the first device to transmit the sensing signal and is not used to transmit communication signals, the first device also supports a second frequency domain resource, the second frequency domain resource being used by the first device to transmit communication signals, and the first frequency domain resource being different from the second frequency domain resource.

[0006] In this embodiment, the first device can support a first frequency domain resource and a second frequency domain resource. The first frequency domain resource is used by the first device to transmit sensing signals but not to transmit communication signals; it can be understood as a resource used for sensing. The second frequency domain resource is used by the first device to transmit communication signals; it can be understood as a resource used for communication. Therefore, this embodiment provides resources for sensing services, which is equivalent to decoupling the resources used for sensing from the resources used for communication. This resolves the contradiction in bandwidth requirements between sensing and communication services, allowing different resources to be used for different services to meet their needs.

[0007] In one optional implementation, the first frequency domain resource is a first carrier, and the second frequency domain resource is a second carrier. One implementation of the frequency domain resource is a carrier, wherein the first carrier may include one or more carriers, the second carrier may include one or more carriers, and the number of carriers included in the first carrier and the second carrier may be the same or different.

[0008] In one optional implementation, the first carrier and the second carrier are located in different frequency bands; or, the first carrier and the second carrier are located in the same frequency band, and the first carrier and the second carrier are discontinuous in the frequency domain; or, the first carrier and the second carrier are located in the same frequency band, and the first carrier and the second carrier are continuous and do not overlap in the frequency domain; or, the first carrier and the second carrier are located in the same frequency band, and the first carrier and the second carrier overlap in the frequency domain. The first carrier and the second carrier can be located in different frequency bands, or in the same frequency band but discontinuous, which can reduce interference between the transmission processes of different devices, and also reduce interference between sensing signals and communication signals. Alternatively, the first carrier and the second carrier can be continuous and do not overlap in the frequency domain, or they can overlap in the frequency domain, thus making full use of the resources in a frequency band to improve spectrum utilization.

[0009] In one optional implementation, the first frequency domain resource is a first BWP, and the second frequency domain resource is a second BWP, wherein the first BWP and the second BWP are located on the same carrier. Another implementation of the frequency domain resource is a carrier, wherein the first BWP may include one or more BWPs, the second BWP may include one or more BWPs, and the number of BWPs included in the first BWP and the second BWP may be the same or different.

[0010] In one optional implementation, the first BWP and the second BWP are discontinuous in the frequency domain; or, the first BWP and the second BWP are continuous in the frequency domain and do not overlap; or, the first BWP and the second BWP overlap in the frequency domain. The first BWP and the second BWP can be located on the same carrier but are discontinuous, which can reduce interference between the transmission processes of different devices and also reduce interference between sensing signals and communication signals. Alternatively, the first BWP and the second BWP can be continuous and non-overlapping in the frequency domain, or they can overlap in the frequency domain, thus making full use of the resources on a single carrier to improve spectrum utilization.

[0011] In one optional implementation, the first frequency domain resource includes M aggregated carriers, and the second frequency domain resource includes N aggregated carriers, where M and N are both positive integers. Another implementation of the frequency domain resource is aggregated carriers, where M can be greater than or equal to 1, N can be greater than or equal to 1, and M and N can be the same or different.

[0012] In one optional implementation, the M carriers include at least one third carrier and at least one fourth carrier, wherein both the at least one third carrier and the at least one fourth carrier are used to transmit sensing signals but not to transmit communication signals; or, the at least one third carrier is used to transmit sensing reference signals but not to transmit communication signals, and the at least one fourth carrier is used to transmit both communication signals and sensing signals. If both the at least one third carrier and the at least one fourth carrier are used to transmit sensing signals but not communication signals, it is equivalent to the carriers used for communication and the carriers used for sensing being different. For example, the M carriers and N carriers have no overlap, and the sensing carriers and communication carriers are decoupled, so they do not affect each other. This satisfies the communication requirements of the first device while improving the sensing accuracy of the first device. Alternatively, if the at least one fourth carrier is used to transmit both communication signals and sensing signals, then the at least one fourth carrier can be used for both sensing and communication. This can be understood as using the communication carrier for sensing as well, thereby providing a larger bandwidth for the sensing signal to further improve the sensing accuracy.

[0013] In one alternative implementation, the M carriers include at least one fourth carrier, and the N carriers include the at least one fourth carrier. Wherein, if the at least one fourth carrier can be used for both communication and sensing, then both the M and N carriers can include at least one fourth carrier. Wherein, the at least one fourth carrier can be used for sensing in the M carriers and for communication in the N carriers.

[0014] In one optional implementation, the first frequency domain resource and the second frequency domain resource belong to a frequency band supported by ORAN. If ORAN supports a frequency band, then the first frequency domain resource and the second frequency domain resource can belong to a frequency band supported by ORAN, making the embodiments of this application applicable to ORAN.

The access network devices include, but are not limited to, base stations (base transceiver stations (BTS), Node B, evolved Node B (eNodeB) / eNB, or the next generation Node B (gNodeB) / gNB), transmission reception points (TRPs), base stations evolved from the 3rd generation partnership project (3GPP), access nodes in wireless fidelity (Wi-Fi) systems, wireless relay nodes, wireless backhaul nodes, etc. The base stations can be: macro base stations, micro base stations, pico base stations, small cells, relay stations, etc. Multiple base stations can support networks using the same access technology or networks using different access technologies. A base station can contain one or more co-located or non-co-located transmission and reception points. The access network equipment can also be a radio controller, centralized unit (CU), and / or distributed unit (DU) in a cloud radioaccess network (CRAN) scenario. The access network equipment can also be a server, etc. For example, the network equipment in V2X technology can be a roadside unit (RSU). The following description uses a base station as an example to illustrate the access network equipment. A base station can communicate with a terminal device, or it can communicate with a terminal device through a relay station. A terminal device can communicate with multiple base stations in different access technologies. The core network equipment is used to implement functions such as mobility management, data processing, session management, policy and billing. The names of the equipment implementing core network functions may differ in systems using different access technologies; this application does not limit this.Taking the 5th generation (5G) mobile communication technology system as an example, the core network equipment includes, for example, access and mobility management function (AMF), session management function (SMF), policy control function (PCF), or user plane function (UPF), etc.

[0091] In a CU-DU architecture, or in an open RAN (ORAN) system, access network equipment may include one or more logical network elements such as a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). CUs and DUs may be separate entities or included in the same network element, such as a baseband unit (BBU). RUs may be included in radio equipment or radio units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs).

[0092] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called an open CU (O-CU), DU can also be called an open DU (O-DU), CU-CP can also be called an open CU-CP (O-CU-CP), CU-UP can also be called an open CU-UP (O-CU-CP), and RU can also be called an open RU (O-RU). For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples in its embodiments. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in the embodiments of this application can be implemented through software modules, hardware modules, or a combination of software modules and hardware modules.

[0093] The CU and DU can be configured according to the protocol layer functions of the wireless network they implement. For example, the CU can be configured to implement the functions of the Packet Data Convergence Protocol (PDCP) layer and above (such as the Radio Resource Control (RRC) layer and / or the Service Data Adaptation Protocol (SDAP) layer); the DU can be configured to implement the functions of protocol layers below the PDCP layer (such as one or more of the Radio Link Control (RLC) layer, Media Access Control (MAC) layer, or Physical (PHY) layer). Alternatively, the CU can be configured to implement the functions of protocol layers above the PDCP layer (such as the RRC and / or SDAP layers), and the DU can be configured to implement the functions of protocol layers below the PDCP layer (such as one or more of the RLC, MAC, or PHY layers).

[0094] The above CU and DU configurations are merely examples; the functions of the CU and DU can be configured as needed. For instance, the CU or DU can be configured to have more protocol layer functions, or only some protocol layer processing functions. For example, some RLC layer functions and protocol layer functions above the RLC layer can be placed in the CU, while the remaining RLC layer functions and protocol layer functions below the RLC layer can be placed in the DU. Furthermore, the functions of the CU or DU can be divided according to service type or other system requirements, such as by latency. Functions that require low latency can be placed in the DU, while functions that do not require low latency can be placed in the CU.

[0095] DU and RU can cooperate to implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of DU and RU can be configured in various ways depending on the design. For example, a DU can be configured to implement baseband functions, and an RU can be configured to implement mid-RF functions. Another example is that a DU can be configured to implement higher-level functions in the PHY layer, and an RU can be configured to implement lower-level functions in the PHY layer, or to implement both lower-level and RF functions. Higher-level functions in the physical layer can include a portion of the physical layer's functions that are closer to the MAC layer, while lower-level functions in the physical layer can include another portion of the physical layer's functions that are closer to the mid-RF side.

[0096] In this application embodiment, the communication device used to implement the functions of a network device can be called a network device. This network device can be a network element, a network device, or a device capable of supporting the network device or network element to implement the function, such as a chip system. This device can be installed in the network device. In the technical solutions provided in this application embodiment, the device used to implement the functions of a network device is described as a network device (for example, the device used to implement the functions of an access network device is an access network device, and the device used to implement the functions of a core network device is a core network device).

[0097] Currently, sensing signals are transmitted on communication resources, but the bandwidth requirements of sensing services and communication services are contradictory. Therefore, communication resources may not be able to simultaneously meet the needs of both sensing and communication services. In view of this, in this embodiment, the first device can support a first frequency domain resource and a second frequency domain resource. The first frequency domain resource is used by the first device to transmit sensing signals and is not used to transmit communication signals; it can be understood as a resource used for sensing. The second frequency domain resource is used by the first device to transmit communication signals; it can be understood as a resource used for communication. Thus, this embodiment provides resources for sensing services, which is equivalent to decoupling the resources used for sensing from those used for communication, resolving the contradiction in bandwidth requirements between sensing and communication services, and allowing different resources to be used for different services to meet their needs. Optionally, the first device may be, for example, a terminal device.

[0098] For reference Figure 1 This is a schematic diagram of a potential perceptual network architecture. Figure 1 It is based on the 5G core network (5G core, 5GC). Figure 1 The network architecture shown can also be an application scenario of the embodiments of this application.

[0099] exist Figure 1 The architecture shown includes a new sensing function (SF) network element. This SF can be a device or component providing sensing capabilities 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 1 Taking deployment in the core network as an example. Figure 1In the network architecture shown, the SF can reuse the interfaces between the location management function (LMF) and other 5GC network elements such as AMF, network exposure function (NEF), unified data management (UDM), network data analytics function (NWDAF), and PCF for sensing interaction. The sensing signaling between the SF and the radio access network (RAN) or UE can be transmitted through the AMF. The sensing measurement data obtained by the RAN or UE can be transmitted to the SF via the control plane, for example, by reusing the long term evolution (LTE) positioning protocol (LPP) or the new radio (NR) positioning protocol annex (NRPPa), or it can be transmitted through the user plane, forwarded to the SF through the UPF, or directly transmitted to the SF.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] Figure 1 Taking the SF (Side Array) as an independent device as an example; alternatively, the SF and LMF (Location Management Array) can be co-located, meaning the network element used for handling sensing services and the network element used for handling positioning services can be the same network element; or the SF can be co-located with other core network elements, such as the AMF (Location Management Array). The LMF is the core network element in 5GC that provides control plane positioning, capable of calculating and feeding back 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.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] NL6: The interface between GMLC and UDM, through which privacy inspection data can be transferred.

[0114] NL2: The interface between NEF and AMF, through which information such as the perceived business type, business requirements, and perceived results can be transmitted.

[0115] NL1: The interface between AMF and LMF, through which information such as perceived business type, business requirements, and perceived results can be transmitted.

[0116] 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.

[0117] Can be referenced again Figure 2 This is a schematic diagram of another potential perceptual network architecture. Figure 2 It is based on 5GC. Figure 2 The network architecture shown can also be another application scenario of the embodiments of this application.

[0118] exist Figure 2In the network architecture shown, 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, or where sensing is the only requirement, this network architecture can provide sensing services without 5GC control or with only a few network elements involved in control. Furthermore, localized deployment of the SF ensures that sensing measurement data or results do not leave the campus, thus meeting enterprises' security and privacy requirements for 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.

[0119] 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.

[0120] 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.

[0121] 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.

[0122] 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).

[0123] 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.

[0124] The technical solutions provided in this application can be applied to fourth-generation (4G) mobile communication systems, such as LTE systems, or to 5G systems, such as NR systems, or to next-generation mobile communication systems or other similar communication systems, such as sixth-generation (6G) mobile communication systems, or to existing satellite mobile communication technology systems; no specific limitations are imposed. For example... Figure 1 and Figure 2 All are based on 5GC. In addition, SF can also be deployed in other networks, such as 6G networks or other future communication networks.

[0125] The embodiments of this application can be applied to Figure 1 or Figure 2 The scenario shown can also be used in other scenarios, such as any scenario involving sensing services.

[0126] The method provided in the embodiments of this application is described below with reference to the accompanying drawings. In various embodiments of this application, the signal used to realize the sensing function or sensing service is referred to as the sensing signal. The sensing signal is transmitted through reflection, scattering, etc., and the sensing device can determine the relevant characteristics of the sensing target based on the received sensing signal. For example, it can estimate the time delay, Doppler, or angular spectrum information based on the received sensing signal to determine the distance, angle, or speed of the sensing target, thereby realizing the sensing function. In various embodiments of this application, the communication signal includes, for example, one or more of the following: physical downlink control channel (PDCCH), physical downlink shared channel (PDSCH), physical uplink control channel (PUCCH), or physical uplink shared channel (PUSCH). In the accompanying drawings corresponding to the various embodiments of this application, all steps indicated by dashed lines are optional steps. The various embodiments herein can be applied to... Figure 1 or Figure 2 The network architecture shown, for example, the first device described in the various embodiments herein, can be... Figure 1 or Figure 2 The UE shown; the network device described in the various embodiments of this document may be Figure 1 or Figure 2 The (R)AN shown.

[0127] This application provides a sensing method, please refer to the embodiments therein. Figure 3 Here is a flowchart of the method.

[0128] S301, the first device transmits a first sensing signal on the first frequency domain resource; correspondingly, the network device receives a second sensing signal on the first frequency domain resource. Alternatively, the network device transmits the first sensing signal on the first frequency domain resource; correspondingly, the first device receives the second sensing signal on the first frequency domain resource. In this application embodiment, the signal used for sensing is referred to as a sensing signal; for example, both the first sensing signal and the second sensing signal are used for sensing. Furthermore, in this application embodiment, the signal used for communication is referred to as a communication signal.

[0129] Taking the first sensing signal transmitted by the first device as an example, for instance, the first sensing signal is sent to the network device. However, the first sensing signal may be reflected, scattered, or diffracted by a sensing target in the environment. Therefore, the second sensing signal received by the network device may be the signal after the first sensing signal has been reflected and / or scattered and / or diffracted by the sensing target in the environment. Again, taking the first sensing signal transmitted by the network device as an example, for instance, the first sensing signal is sent to the first device. However, the first sensing signal may be reflected and / or scattered by a sensing target in the environment. Therefore, the second sensing signal received by the first device may be the signal after the first sensing signal has been reflected and / or scattered and / or diffracted by the sensing target in the environment.

[0130] In this embodiment, the network device is, for example, a network equipment, such as an access network device. The network device can send a first sensing signal to the first device and receive a second sensing signal from the environment. Alternatively, the network device can be, for example, a CU in the access network device. The network device can send the first sensing signal to a DU in the access network device, which then sends the first sensing signal to an RU in the access network device, and the RU then sends the first sensing signal to the first device; or, the second sensing signal can reach the RU in the access network device, which sends the second sensing signal to the DU in the access network device, and the DU then sends the second sensing signal to the CU. Alternatively, the network device can be, for example, a DU in the access network device. The network device can send the first sensing signal to the RU in the access network device, which then sends the first sensing signal to the first device; or, the second sensing signal can reach the RU in the access network device, which sends the second sensing signal to the DU. Alternatively, the network device can be, for example, a RU in the access network device. The RU can send the first sensing signal to the first device; or, the second sensing signal can reach the RU.

[0131] The first frequency domain resource can be used by the first device to transmit sensing signals but not for transmitting communication signals; therefore, the first frequency domain resource can be considered a sensing resource. Optionally, since the first frequency domain resource is not used for transmitting communication signals, it can also be considered a dedicated sensing resource. For example, the first frequency domain resource can also be called a sensing resource, a dedicated sensing resource, a resource for sensing, a resource dedicated to sensing, a sensing signal transmission resource, a sensing signal resource, or a dedicated sensing signal resource, etc. The embodiments of this application do not limit the name.

[0132] In addition, the first device also supports a second frequency domain resource, which can be used by the first device to transmit communication signals. Therefore, the second frequency domain resource can be considered a communication resource. The second frequency domain resource may not be used for transmitting sensing signals by the first device, or it may be used for transmitting sensing signals by the first device; this application embodiment does not impose any limitations on this. For example, the second frequency domain resource may also be called a communication resource, a resource used for communication, a communication signal transmission resource, or a communication signal resource, etc. This application embodiment does not impose any limitations on the name.

[0133] Optionally, the method may further include S302, in which the first device may transmit a first communication signal on the second frequency domain resource; correspondingly, the network device receives the first communication signal from the first device on the first frequency domain resource. Alternatively, S302 includes the network device transmitting the first communication signal on the second frequency domain resource; correspondingly, the first device receives the first communication signal from the network device on the first frequency domain resource. S302 may occur before or after S301.

[0134] Optionally, the first frequency domain resources and / or the second frequency domain resources can be configured by the network device to the first device. For example, the network device can send first information, which can be used to configure the first frequency domain resources. The first information may be included in an RRC message, such as an RRC reconfiguration message; or the first information may also be included in messages of other protocol layers, such as MAC control element (CE). As another example, the network device can send second information, which can be used to configure the second frequency domain resources. The second information may be included in an RRC message, such as an RRC reconfiguration message; or the second information may also be included in messages of other protocol layers, such as MAC CE. The first information and the second information can be the same information, which can be used to configure the first and second frequency domain resources; or the first information and the second information can be different information. If the first information and the second information are different information, they can be included in the same message, or they can be included in different messages. If the first information and the second information are included in different messages, the different messages can be messages of the same protocol layer, such as both being RRC messages; or the different messages can be messages of different protocol layers. The steps for the network device to send the first information and / or the second information can be referred to in S303. Optionally, S303 may occur before S301. In addition, S302 may occur before S303, or after S303, or simultaneously with S303.

[0135] The first frequency domain resources and the second frequency domain resources can be different. This means that the resources used for sensing and the resources used for communication are decoupled in this embodiment of the application, which resolves the contradiction between the bandwidth requirements of sensing services and communication services, and allows different resources to be used for different services to meet the needs of different services.

[0136] Optionally, the bandwidth of the first frequency domain resource can be greater than the bandwidth of the second frequency domain resource, and / or the bandwidth of the first frequency domain resource can be greater than a first threshold. The first threshold may be set by the network device or predefined by a protocol; for example, the first threshold may be related to the accuracy of the sensing service. The first frequency domain resource is used to transmit the sensing service. For the sensing service, a larger bandwidth results in higher sensing accuracy; therefore, the bandwidth of the first frequency domain resource can be relatively large. However, regarding the bandwidth of the first frequency domain resource and the bandwidth of the second frequency domain resource, the embodiments of this application are not limited to the first frequency domain resource having a bandwidth greater than the second frequency domain resource; for example, the bandwidth of the first frequency domain resource may also be less than or equal to the bandwidth of the second frequency domain resource.

[0137] There are multiple ways to implement the first and second frequency domain resources, as illustrated in the following examples.

[0138] 1. As a first optional implementation of the first frequency domain resource and the second frequency domain resource, the first frequency domain resource is, for example, a first carrier, and the second frequency domain resource is, for example, a second carrier.

[0139] The first carrier may include one or more carriers; the second carrier may include one or more carriers. Wherein, if the first carrier includes multiple carriers, the number of carriers included in the first carrier and the number of carriers included in the second carrier may be equal or unequal. Furthermore, if the first carrier includes multiple carriers, these multiple carriers may be continuous or discontinuous in the frequency domain; if the second carrier includes multiple carriers, these multiple carriers may be continuous or discontinuous in the frequency domain. The term "carrier" may not be used in the future; it may be referred to as frequency band, carrier frequency, carrier unit, or other names. This application does not limit the name; in this description, "carrier" is used as an example.

[0140] Optionally, the bandwidth of the first carrier is greater than the bandwidth of the second carrier. This allows the first device to communicate on the carrier with a smaller bandwidth and perform sensing on the carrier with a larger bandwidth, satisfying both communication requirements and improving sensing accuracy. Since the first device does not need to perform communication services on the carrier with a larger bandwidth, it only needs to be equipped with simple signal processing capabilities. For example, it does not need to be equipped with processing capabilities for complex signals such as communication signals. Therefore, the embodiments of this application improve sensing accuracy while simplifying the processing capabilities of the first device, saving power consumption, and achieving low-cost, high-precision sensing.

[0141] Wherein, if the first carrier includes multiple carriers and the second carrier includes multiple carriers, and the bandwidth of the first carrier is greater than the bandwidth of the second carrier, it can mean that the total bandwidth of the multiple carriers included in the first carrier is greater than the total bandwidth of the multiple carriers included in the second carrier; or it can mean that the bandwidth of each carrier among the multiple carriers included in the first carrier is greater than the bandwidth of the carrier with the largest bandwidth included in the second carrier; or it can mean that the bandwidth of each carrier among the multiple carriers included in the first carrier is greater than the bandwidth of one of the carriers included in the second carrier.

[0142] The first carrier and the second carrier can have different relationships, as illustrated by the examples below.

[0143] (1) As a first alternative relationship between the first carrier and the second carrier, the first carrier and the second carrier are located in different frequency bands (or frequency bands).

[0144] Here, a frequency band can be a frequency range (FR) or the operating range of the electromagnetic spectrum. According to the definition of the 3rd Generation Partnership Project (3GPP), each frequency band can correspond to a number or index, which is also called a frequency band number. Taking a 5G system as an example, 5G NR can include two frequency ranges, namely frequency range 1 (FR1) and frequency range 2 (FR2).

[0145] Frequency range 1 may include frequency bands below 6 GHz, such as the band between 410 MHz and 7125 MHz; frequency range 2 may include frequency bands in the millimeter wave range, such as the band between 24.25 GHz and 71 GHz.

[0146] For the frequency ranges FR1 and FR2, 3GPP further subdivided them into multiple 5G NR bands, each corresponding to a band number. These band numbers begin with "n," for example, the 5G NR band numbers include n1, n2, ..., n260. The specific frequencies corresponding to each band can be found in the standard specification TS38.101. For example, band n1 has an uplink operating frequency of 1920MHz to 1980MHz and a downlink operating frequency range of 2110MHz to 2170MHz; similarly, band n260 has an uplink operating frequency of 37000MHz to 40000MHz and a downlink operating frequency range of 37000MHz to 40000MHz.

[0147] For example, the first carrier is located in frequency band A, and the second carrier is located in frequency band B. Frequency band A and frequency band B are different frequency bands. (For more information, please refer to...) Figure 4A As an example, frequency band A and frequency band B are both 5G frequency bands; or, frequency band A is a 5G frequency band and frequency band B is a 6G frequency band; or, frequency band A is a 6G frequency band and frequency band B is a 5G frequency band; or, frequency band A and / or frequency band B are both 6G frequency bands; or, frequency band A and / or frequency band B are frequency bands for other future communication systems. In the embodiments of this application, the 5G frequency band is, for example, the aforementioned 5G NR frequency band.

[0148] On the first carrier, the first device and the network device can transmit sensing signals but not communication signals. On the second carrier, the first device and the second device can transmit communication signals, and optionally, they can also transmit sensing signals.

[0149] In this configuration, the first carrier is used by the first device to transmit sensing signals but not for transmitting communication signals. Additionally, the first carrier may also be used by other devices to transmit sensing signals and / or communication signals. The second carrier is used by the first device to transmit communication signals, and additionally, the first carrier may also be used by other devices to transmit sensing signals and / or communication signals. For example, while the first device is transmitting sensing signals on the first carrier, other devices may utilize the second carrier to transmit sensing signals or communication signals. Placing the first and second carriers in different frequency bands can reduce interference between the transmission processes of different devices.

[0150] (2) As a second alternative relationship between the first carrier and the second carrier, the first carrier and the second carrier are located in the same frequency band and are not continuous in the frequency domain.

[0151] For example, the first carrier is located in frequency band A, and the second carrier is also located in frequency band A, but the first carrier and the second carrier are not continuous in the frequency domain. This can be referred to... Figure 4B As an example, band A is a 5G band; or, band A is a 6G band; or, band A may also be a band for other future communication systems.

[0152] On the first carrier, the first device and the network device can transmit sensing signals but not communication signals. On the second carrier, the first device and the second device can transmit communication signals, and optionally, they can also transmit sensing signals.

[0153] For example, while the first device is transmitting a sensing signal on the first carrier, other devices may use the second carrier to transmit sensing or communication signals. Making the first and second carriers discontinuous in the frequency domain can reduce interference between the transmission processes of different devices.

[0154] (3) As a third alternative relationship between the first carrier and the second carrier, the first carrier and the second carrier are located in the same frequency band and are continuous in the frequency domain, but do not overlap in the frequency domain. Wherein, if the first carrier includes multiple carriers and the second carrier includes multiple carriers, then the continuity of the first carrier and the second carrier in the frequency domain can mean that a certain carrier included in the first carrier and a certain carrier included in the second carrier are continuous in the frequency domain.

[0155] For example, the first carrier is located in frequency band A, the second carrier is also located in frequency band A, and the first and second carriers are continuous in the frequency domain. This can be referenced from [reference needed]. Figure 4C As an example, band A is a 5G band; or, band A is a 6G band; or, band A may also be a band for other future communication systems.

[0156] On the first carrier, the first device and the network device can transmit sensing signals but not communication signals. On the second carrier, the first device and the second device can transmit communication signals, and optionally, they can also transmit sensing signals.

[0157] Making the first and second carriers continuous in the frequency domain can minimize interference between transmission processes of different devices and fully utilize the resources of a frequency band, thereby improving spectrum resource utilization. For example, the total bandwidth of frequency band A can be the total bandwidth of the first and second carriers, meaning that the spectrum resources of frequency band A can be fully utilized.

[0158] (4) As a fourth optional relationship between the first carrier and the second carrier, the first carrier and the second carrier are located in the same frequency band and overlap in the frequency domain, for example, the first carrier and the second carrier may partially overlap in the frequency domain. Wherein, if the first carrier includes multiple carriers and the second carrier includes multiple carriers, then the overlap of the first carrier and the second carrier in the frequency domain may mean that at least one carrier included in the first carrier overlaps with at least one carrier included in the second carrier in the frequency domain.

[0159] For example, if the first carrier is located in frequency band A, and the second carrier is also located in frequency band A, and the first and second carriers overlap in the frequency domain, this can be referred to... Figure 4D The shaded areas represent overlapping portions. As an example, band A is a 5G band; or, band A is a 6G band; or, band A may also be a band for other future communication systems.

[0160] On the first carrier, the first device and the network device can transmit sensing signals but not communication signals. On the second carrier, the first device and the second device can transmit communication signals, and optionally, they can also transmit sensing signals.

[0161] In this scenario, the first carrier and the second carrier overlap in the frequency domain. Therefore, in the overlapping area, both sensing signals and communication signals may need to be transmitted. Optionally, the first device can transmit sensing signals and communication signals in a time-division multiplexing manner, which is equivalent to time-division multiplexing of sensing signals and communication signals, thereby reducing the conflict and interference between sensing signals and communication signals.

[0162] By overlapping the first and second carriers in the frequency domain, the resources of a frequency band can be fully utilized, thereby improving the spectrum resource utilization rate. For example, the total bandwidth of frequency band A can be the total bandwidth of the first and second carriers, meaning that the spectrum resources of frequency band A can be fully utilized.

[0163] 2. As a second optional implementation of the first frequency domain resource and the second frequency domain resource, the first frequency domain resource is, for example, a first bandwidth part (BWP), and the second frequency domain resource is, for example, a second BWP.

[0164] A Block Frequency Cover (BWP) is a portion of the bandwidth on a carrier, occupying a portion of the carrier's frequency domain resources. For example, a carrier #0 can contain multiple BWPs, such as BWP#0, BWP#1, BWP#2, etc. Each BWP can correspond to a set of resource blocks (RBs), subcarrier spacing, and cyclic prefix (CP) type. Optionally, multiple BWPs can be configured on a single carrier, but at most one BWP can be active at any given time.

[0165] The first BWP may include one or more BWPs; the second BWP may include one or more BWPs. If the first BWP includes multiple BWPs, and the second BWP includes multiple BWPs, the number of BWPs included in the first BWP and the number of BWPs included in the second BWP may be equal or unequal. Furthermore, if the first BWP includes multiple BWPs, these multiple BWPs may be continuous or discontinuous in the frequency domain; similarly, if the second BWP includes multiple BWPs, these multiple BWPs may be continuous or discontinuous in the frequency domain. The term "BWP" may not be used in the future; it may be referred to as a virtual BWP, virtual bandwidth, resource block, bandwidth unit, or other names. This application does not limit the name; in this description, "BWP" is used as an example.

[0166] Optionally, the bandwidth of the first BWP is greater than that of the second BWP. This allows the first device to communicate on the BWP with a smaller bandwidth and perform sensing on the BWP with a larger bandwidth, satisfying both communication requirements and improving sensing accuracy. Since the first device does not need to perform communication services on the BWP with a larger bandwidth, it only needs to be equipped with simple signal processing capabilities. For example, it does not need to be equipped with processing capabilities for complex signals such as communication signals. Therefore, the embodiments of this application improve sensing accuracy while simplifying the processing capabilities of the first device, saving power consumption, and achieving low-cost, high-precision sensing.

[0167] Wherein, if the first BWP includes multiple BWPs, the second BWP includes multiple BWPs, and the bandwidth of the first BWP is greater than the bandwidth of the second BWP, it can mean that the total bandwidth of the multiple BWPs included in the first BWP is greater than the total bandwidth of the multiple BWPs included in the second BWP; or it can mean that among the multiple BWPs included in the first BWP, the bandwidth of each BWP in at least one BWP is greater than the bandwidth of the BWP with the largest bandwidth included in the second BWP; or it can mean that among the multiple BWPs included in the first BWP, the bandwidth of each BWP in at least one BWP is greater than the bandwidth of one of the BWPs included in the second BWP.

[0168] The first BWP and the second BWP can have different relationships, as illustrated in the following examples.

[0169] (1) As a first alternative relationship between the first BWP and the second BWP, the first BWP and the second BWP are located on the same carrier and are not continuous in the frequency domain.

[0170] For example, the first BWP is located on carrier A, and the second BWP is also located on carrier A, but the first BWP and the second BWP are not continuous in the frequency domain. For this, please refer to... Figure 5A As an example, carrier A can belong to frequency band A, which can be a 5G frequency band; or, frequency band A can be a 6G frequency band; or, frequency band A may also be a frequency band for other future communication systems.

[0171] On the first BWP, the first device and the network device can transmit sensing signals but not communication signals. On the second BWP, the first device and the second device can transmit communication signals, and optionally, they can also transmit sensing signals.

[0172] For example, while the first device is transmitting a sensing signal using the first BWP, other devices may use the second BWP to transmit sensing or communication signals. Making the first and second BWP discontinuous in the frequency domain can reduce interference between the transmission processes of different devices.

[0173] (2) As a second alternative relationship between the first BWP and the second BWP, the first BWP and the second BWP are located on the same carrier and are continuous in the frequency domain, but do not overlap in the frequency domain. Wherein, if the first BWP includes multiple carriers and the second BWP includes multiple BWPs, then the continuity of the first BWP and the second BWP in the frequency domain can mean that a certain BWP included in the first BWP is continuous in the frequency domain with a certain BWP included in the second BWP.

[0174] For example, the first BWP is located on carrier A, and the second BWP is also located on carrier A, and the first BWP and the second BWP are continuous in the frequency domain. This can be referenced from [reference needed]. Figure 5B As an example, carrier A belongs to frequency band A, which could be a 5G frequency band; or, frequency band A could be a 6G frequency band; or, frequency band A could also be a frequency band for other future communication systems.

[0175] On the first BWP, the first device and the network device can transmit sensing signals but not communication signals. On the second BWP, the first device and the second device can transmit communication signals, and optionally, they can also transmit sensing signals.

[0176] Making the first BWP and the second BWP continuous in the frequency domain can minimize interference between the transmission processes of different devices and fully utilize the resources on a single carrier, thereby improving spectrum resource utilization. For example, the total bandwidth of carrier A can be the total bandwidth of the first BWP and the second BWP, meaning that the spectrum resources of carrier A can be fully utilized.

[0177] (3) As a third alternative relationship between the first BWP and the second BWP, the first BWP and the second BWP are located on the same carrier and overlap in the frequency domain, for example, the first BWP and the second BWP may partially overlap in the frequency domain. Wherein, if the first BWP includes multiple BWPs and the second BWP includes multiple BWPs, then the overlap of the first BWP and the second BWP in the frequency domain may mean that at least one BWP included in the first BWP overlaps with at least one BWP included in the second BWP in the frequency domain.

[0178] For example, the first BWP is located on carrier A, and the second BWP is also located on carrier A, and the first BWP and the second BWP overlap in the frequency domain. This can be referenced. Figure 5C The shaded areas represent overlapping portions. As an example, carrier A belongs to frequency band A, which could be a 5G band; or, frequency band A could be a 6G band; or, frequency band A could also be a frequency band for other future communication systems.

[0179] On the first BWP, the first device and the network device can transmit sensing signals but not communication signals. On the second BWP, the first device and the second device can transmit communication signals, and optionally, they can also transmit sensing signals.

[0180] In this case, the first BWP and the second BWP overlap in the frequency domain. Therefore, in the overlapping area, it may be necessary to transmit both sensing signals and communication signals. Optionally, the first device can transmit sensing signals and communication signals in a time-division multiplexing manner, which is equivalent to time-division multiplexing of sensing signals and communication signals, thereby reducing the conflict and interference between sensing signals and communication signals.

[0181] By overlapping the first BWP and the second BWP in the frequency domain, the resources on a single carrier can be fully utilized, thereby improving spectrum resource utilization. For example, the total bandwidth of carrier A can be the total bandwidth of the first BWP and the second BWP, meaning that the spectrum resources of carrier A can be fully utilized.

[0182] 3. As a third optional implementation of the first and second frequency domain resources, the first frequency domain resource includes, for example, M aggregated carriers, and the second frequency domain resource includes, for example, N aggregated carriers, where M and N are both positive integers. M can be equal to N, or it can be different from N, and there is no restriction on the relationship between M and N. Wherein, if M is greater than 1, the bandwidths of different carriers among the M carriers can be the same or different. If N is greater than 1, the bandwidths of different carriers among the N carriers can be the same or different.

[0183] For example, the aggregated M carriers correspond to (or are associated with) a first carrier aggregation (CA) supported by a first device; the first CA can also be called a sensing CA. The aggregated N carriers can correspond to (or are associated with) a second CA supported by the first device; the second CA can also be called a communication CA. For example, a sensing CA can correspond to or be associated with a first carrier set, which may include the aggregated M carriers; a communication CA can correspond to or be associated with a second carrier set, which may include the aggregated N carriers. As another example, a sensing CA can correspond to or be associated with a first carrier list, which includes information about the M carriers; a communication CA can correspond to or be associated with a second carrier list, which includes information about the N carriers.

[0184] Optionally, the aggregated bandwidth of M carriers is greater than the aggregated bandwidth of N carriers. This allows the first device to communicate on carriers with smaller bandwidths and perform sensing on carriers with larger bandwidths, satisfying both communication requirements and improving sensing accuracy. Since the first device does not need to perform communication services on carriers with larger bandwidths, it only needs to be equipped with simple signal processing capabilities. For example, it does not need to be equipped with processing capabilities for complex signals such as communication signals. Therefore, the embodiments of this application improve sensing accuracy while simplifying the processing capabilities of the first device, saving power consumption, and achieving low-cost, high-precision sensing.

[0185] The M carriers may include at least one third carrier and at least one fourth carrier, wherein the number of at least one third carrier and the number of at least one fourth carrier may be the same or different. The at least one third carrier may be used to transmit sensing signals but not to transmit communication signals; for example, all at least one third carrier may be a sensing carrier. The at least one fourth carrier may have different implementations, as illustrated below.

[0186] (1) As a first optional implementation of the at least one fourth carrier, the at least one fourth carrier is also used to transmit sensing signals but not to transmit communication signals. For example, see reference. Figure 6A , is an example of M carriers. Figure 6A Taking the M carriers, including sensing carrier 1 and sensing carrier 2, as an example, sensing carrier 1 belongs to at least one third carrier, and sensing carrier 2 belongs to at least one fourth carrier.

[0187] In this implementation, the sensing CA is associated with the sensing carrier but not the communication carrier, and the communication CA is associated with the communication carrier but not the sensing carrier. This is equivalent to the carrier used for communication and the carrier used for sensing being different. For example, M carriers and N carriers have no intersection. The sensing carrier and the communication carrier are decoupled and do not affect each other. This satisfies the communication requirements of the first device and improves the sensing accuracy of the first device.

[0188] (2) As a second optional implementation of the at least one fourth carrier, the at least one fourth carrier is used to transmit communication signals. For example, see reference... Figure 6B , is an example of M carriers. Figure 6B Taking the M carriers, including sensing carrier 1 and communication carrier 3, as an example, sensing carrier 1 belongs to at least one third carrier, and communication carrier 3 belongs to at least one fourth carrier.

[0189] In this implementation, the sensing CA is associated with both a sensing carrier and a communication carrier, while the communication CA is associated with a communication carrier but not with a sensing carrier. Optionally, the N carriers also include at least one fourth carrier, meaning that the at least one fourth carrier is associated with both the sensing CA and the communication CA. This is equivalent to the communication carrier also being used for sensing, thereby providing a larger bandwidth for the sensing signal to further improve sensing accuracy. Optionally, the first device can transmit the sensing signal and the communication signal in a time-division multiplexing manner, which is equivalent to time-division multiplexing the sensing signal and the communication signal. Therefore, even if the communication carrier is also used for sensing, since the sensing signal and the communication signal can be transmitted at different times, the conflict and interference between the sensing signal and the communication signal can be reduced.

[0190] In summary, in this embodiment, the first device can support a first frequency domain resource and a second frequency domain resource. The first frequency domain resource is used by the first device to transmit sensing signals but not to transmit communication signals; it can be understood as a resource used for sensing. The second frequency domain resource is used by the first device to transmit communication signals; it can be understood as a resource used for communication. Therefore, this embodiment provides resources for sensing services, which is equivalent to decoupling the resources used for sensing from the resources used for communication. This resolves the contradiction in bandwidth requirements between sensing and communication services, allowing different resources to be used for different services to meet their needs.
