Description

Technical Field

[0001] This application relates to the field of communications, and more particularly to a resource allocation method and related apparatus. Background Technology

[0002] In the evolution of fifth-generation (5G) mobile communication systems, integrated communication and sensing technology is considered one of the key technologies for expanding the service capabilities of mobile communication networks. This technology can also be called sensing technology. The core idea is to add sensing capabilities to the mobile communication network, building the ability to detect, track, and image targets. This integrates communication and sensing capabilities into a single network.

[0003] Sensing technology is based on the interaction between communication devices and their surrounding environment. It achieves perception and monitoring of the surrounding environment by collecting and analyzing sensing signals received by the communication device. Taking a scenario where an access network device sends a sensing signal, and the communication device receives that signal, as an example, the access network device sends a sensing signal to the environment, and then the communication device collects and analyzes the received sensing signal to achieve perception.

[0004] The coverage area of ​​a sensing signal is referred to as its zone, region, cell, or area; similarly, the coverage area of ​​a communication signal is referred to as its zone or cell. Currently, each communication cell only configures sensing resources for its own communication devices; these resources refer to the resources for receiving or transmitting sensing signals. However, the applicant's research has found that the coverage area of ​​a sensing signal is usually larger than that of a communication signal. Therefore, the sensing area and the communication cell may not be the same. How to configure sensing resources for communication devices when the sensing area and the communication cell are inconsistent becomes an urgent problem to be solved. Summary of the Invention

[0005] This application proposes a resource allocation method and related apparatus, which solves the problem of configuring sensing resources when the sensing area and the communication cell are inconsistent.

[0006] In a first aspect, embodiments of this application propose a resource allocation method, which is applied to a first device.

[0007] In one possible implementation, the first device is a network-side device, also referred to as a network device. This network device is, for example, an access network device, or other device including access network device functions, or a circuit, or a system-on-a-chip (or chip), or other functional module capable of implementing the functions of the network device, and is, for example, disposed within the network device. The access network device can be a non-open RAN (openRAN, O-RAN, or ORAN) architecture or an ORAN architecture; alternatively, the access network device can be a centralized unit (CU), distributed unit (DU), or radio unit (RU) under an ORAN architecture. The access network device may be located on the ground, for example, or on a satellite, or located on a satellite.

[0008] In another possible implementation, the first device is a computing device. This first device can be the computing device itself, a device or apparatus with a chip, a device or apparatus with integrated circuitry, or a chip, chip system, module, control unit, circuit, or processor within the aforementioned device or apparatus. When the first device is a computing device, it can be referred to as a sensing unit.

[0009] The method includes: a first device sending first configuration information to a second device, the first configuration information being used to configure first sensing resources, the first sensing resources being used by the second device within a first sensing area to receive and / or send sensing signals, the first sensing area including one or more communication cells.

[0010] For example, the second device includes, but is not limited to: CU, DU, terminal equipment, or other access network equipment different from the second device.

[0011] For example, the first sensing area includes one or more communication cells, or it can be replaced by one or more communication cells belonging to the first sensing area, or the first sensing area being associated with one or more communication cells, or the range corresponding to the first sensing area being the same as the range corresponding to the one or more communication cells.

[0012] In the above technical solution, since the first sensing area includes one or more communication cells, after the first device sends the first configuration information to the second devices of the one or more communication cells within the first sensing area, the second devices of the one or more communication cells can determine the first sensing resources based on the first configuration information, and then receive and / or send sensing signals according to the first sensing resources to achieve sensing. This solves the problem of configuring sensing resources when the sensing area and the communication cells are inconsistent.

[0013] In conjunction with the first aspect, in one possible implementation of the first aspect, the method further includes: a first device receiving second configuration information, the second configuration information indicating a first sensing area; and the first device determining the first configuration information based on the second configuration information.

[0014] It should be noted that the first sensing area can also be replaced by: the first sensing range, the first sensing cell, the first sensing supercell, or the first sensing signal coverage area. This application embodiment does not limit this.

[0015] Optionally, the second configuration information can also be used to indicate that the first sensing area is associated with one or more communication cells, or the second configuration information can also be used to indicate that one or more communication cells belong to the first sensing area.

[0016] It should be noted that the first device can determine different first configuration information for different sensing areas, that is, the first configuration information is different for different sensing areas; or, the first device can determine the same first configuration information for different sensing areas, that is, different sensing areas reuse the same first configuration information.

[0017] In the above technical solution, the first device can also determine the first sensing area based on the second configuration information to ensure that the first device can configure the corresponding first sensing resources for the first sensing area.

[0018] In conjunction with the first aspect, in one possible implementation of the first aspect, the method further includes: sending second configuration information to the second device.

[0019] Specifically, after receiving the second configuration information, the first device can also act as a relay to send the second configuration information to the second device to ensure that the second device can determine the first sensing area based on the second configuration information.

[0020] In conjunction with the first aspect, in one possible implementation of the first aspect, the second configuration information includes one or more of the following: identification information of the first sensing area, or identification information of one or more communication cells.

[0021] In one example, the second configuration information includes the identification information of the first sensing area. Then, the first device determines the one or more communication cells associated with the first sensing area based on the one or more communication cells it manages. The one or more communication cells associated with the first sensing area belong to the one or more communication cells managed by the first device itself.

[0022] In another example, the second configuration information includes the identification information of the first sensing area and the identification information of one or more communication cells. In this case, the first device directly determines the first sensing area and one or more communication cells associated with the first sensing area based on the second configuration information.

[0023] In another example, the second configuration information includes the identification information of one or more communication cells. The first device, based on the second configuration information and the identification information of the sensing areas it maintains, assigns corresponding identification information of a first sensing area to the one or more communication cells. This establishes an association between the first sensing area and the one or more communication cells, and the identification information of the first sensing area belongs to the identification information of the sensing areas maintained by the first device itself.

[0024] In conjunction with the first aspect, in one possible implementation of the first aspect, the first device sends first configuration information, including: sending the first configuration information to a second device, wherein the first device is a first access network device; the second device is a second access network device, and the first access network device and the second access network device are different.

[0025] For example, the first device sending the first configuration information to the second device can specifically be a first access network device sending the first configuration information to a second access network device. The first access network device corresponds to a first sensing area, and the second access network device corresponds to a second sensing area, which are different from each other. Therefore, the second access network device performs resource scheduling based on the first configuration information. When allocating resources to terminal devices within the second sensing area, the second access network device can bypass the first sensing resources, reducing interference between cells.

[0026] In conjunction with the first aspect, in one possible implementation of the first aspect, the first configuration information includes: identification information of the first sensing area, and / or, identification information of one or more communication cells.

[0027] In the above technical solution, the first configuration information can explicitly indicate that the sensing area corresponding to the first sensing resource is the first sensing area.

[0028] In conjunction with the first aspect, in one possible implementation of the first aspect, the first configuration information further includes one or more of the following: the time-domain resource location of the first sensing resource; the frequency-domain resource location of the first sensing resource; or, the antenna port used by the first sensing resource.

[0029] Specifically, the first configuration information is used to configure the time-domain resource location, the frequency-domain resource location, and / or the antenna port used by the first sensing resource. The time-domain resource location of the first sensing resource can also be referred to as the time-domain resource used by the sensing signal within the first sensing area, or the time-domain resource occupied by the first sensing resource. Similarly, the frequency-domain resource location of the first sensing resource can also be referred to as the frequency-domain resource used by the sensing signal within the first sensing area, or the frequency-domain resource occupied by the first sensing resource. The antenna port used by the first sensing resource can also be referred to as the spatial resource used by the sensing signal within the first sensing area, or the spatial resource occupied by the first sensing resource.

[0030] Secondly, embodiments of this application propose a resource allocation method, which is applied to a second device.

[0031] In one possible implementation, the second device is a network-side device, also referred to as a network device. This network device is, for example, an access network device, or other device including access network device functions, or a circuit, or a system-on-a-chip (or chip), or other functional module capable of implementing the functions of the network device, and is, for example, disposed within the network device. The access network device can be a non-ORAN architecture or an ORAN architecture; alternatively, the access network device can be a CU, DU, or RU under an ORAN architecture. The access network device may be located on the ground, for example, or on a satellite, or located on a satellite.

[0032] In another possible implementation, the second device is a terminal device, which can be the terminal device itself, a device or apparatus with a chip, a device or apparatus with integrated circuitry, or a chip, chip system, module, control unit, circuitry, or processor in the aforementioned device or apparatus.

[0033] The method includes: a second device receiving first configuration information, the first configuration information being used to configure first sensing resources, wherein the second device is located within a first sensing area, the first sensing area including one or more communication cells; the second device determining the first sensing resources according to the first configuration information; and the second device receiving and / or transmitting sensing signals based on the first sensing resources.

[0034] In the above technical solution, since the first sensing area includes one or more communication cells, after the first device sends the first configuration information to the second devices of the one or more communication cells within the first sensing area, the second devices of the one or more communication cells can determine the first sensing resources based on the first configuration information, and then receive and / or send sensing signals according to the first sensing resources to achieve sensing. This solves the problem of configuring sensing resources when the sensing area and the communication cells are inconsistent.

[0035] In conjunction with the second aspect, in one possible implementation of the second aspect, the method further includes: receiving second configuration information, the second configuration information indicating the first sensing area.

[0036] It should be noted that the first sensing area can also be replaced by: the first sensing range, the first sensing cell, the first sensing supercell, or the first sensing signal coverage area. This application embodiment does not limit this.

[0037] Optionally, the second configuration information can also be used to indicate that the first sensing area is associated with one or more communication cells, or the second configuration information can also be used to indicate that one or more communication cells belong to the first sensing area.

[0038] In the above technical solution, after receiving the second configuration information, the first device can also act as a relay to send the second configuration information to the second device, so as to ensure that the second device can determine the first sensing area according to the second configuration information. The second device can also determine the first sensing area according to the second configuration information, so as to ensure that the second device can use the first sensing resources corresponding to the first sensing area.

[0039] In conjunction with the second aspect, in one possible implementation of the second aspect, the second configuration information includes one or more of the following: identification information of the first sensing area, or identification information of one or more communication cells.

[0040] In conjunction with the second aspect, in one possible implementation of the second aspect, the first configuration information includes: identification information of the first sensing area, and / or, identification information of one or more communication cells.

[0041] In conjunction with the second aspect, in one possible implementation of the second aspect, the first configuration information further includes one or more of the following: the time-domain resource location of the first sensing resource; the frequency-domain resource location of the first sensing resource; or, the antenna port used by the first sensing resource.

[0043] Thirdly, embodiments of this application propose a resource allocation method, which is applied to a third device.

[0044] In one possible implementation, the third device is a core network device. The third device can be the core network device itself, which can be a device or apparatus with a chip, or a device or apparatus with integrated circuits, or a chip, chip system, module, control unit, circuit, or processor in the aforementioned device or apparatus. This application does not limit the specific implementation.

[0045] For example, the third device may be a sensing function.

[0046] The method includes: a third device sending second configuration information, the second configuration information indicating a first sensing area, the first sensing area including one or more communication cells.

[0047] It should be noted that the first sensing area can also be replaced by: the first sensing range, the first sensing cell, the first sensing supercell, or the first sensing signal coverage area. This application embodiment does not limit this.

[0049] In the above technical solution, the third device sends second configuration information, so that the first device or the second device determines the first sensing area according to the second configuration information, so as to ensure that the first device can configure the corresponding first sensing resources for the first sensing area.

[0050] In conjunction with the third aspect, in one possible implementation of the third aspect, sending the second configuration information includes: sending the second configuration information to the second device; and / or sending the second configuration information to the first device; wherein the second configuration information is used by the first device to determine the first configuration information, the first configuration information is used to configure the first sensing resource, the second device is located within the first sensing area, and the first sensing resource is used by the second device to receive and / or send sensing signals.

[0087] References to "one embodiment" or "some embodiments" as described in this application mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0088] In the description of this application, unless otherwise stated, " / " means "or". For example, A / B can mean A or B. "And / or" in this document is merely a description of 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, and B alone. Furthermore, "at least one" means one or more, and "multiple" means two or more. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or multiple 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.

[0089] First, the communication system involved in the embodiments of this application is introduced. This application can be applied to long-term evolution (LTE) systems, new radio (NR) systems, or future communication systems after 5G (such as 6G). The communication system includes at least one access network device and / or at least one terminal device.

[0090] Figure 1 This is a schematic diagram of the architecture of the communication system 1000 used in the embodiments of this application.

[0091] like Figure 1 As shown, the communication system includes a wireless access network 100 and a core network 200. Optionally, the communication system 1000 may also include an Internet 300. The wireless access network 100 may include at least one network-side device (the network-side device in this embodiment can also be understood as an access network device, such as...). Figure 1 The 110a and 110b in the diagram (the network-side device can also be referred to as a network equipment) may also include at least one terminal (which can also be understood as the terminal equipment described above, such as...). Figure 1(e.g., 120a-120j). Furthermore, the access network equipment (or wireless access network equipment) can be a macro base station (such as...). Figure 1 110a in the text), can also be a micro base station or an indoor station (such as... Figure 1 110b) in the above can also be a relay node or a donor node, etc. It is understood that all or part of the functions of the access network device in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (e.g., a cloud platform). The embodiments of this application do not limit the specific technology or specific device form used in the wireless access network device.

[0092] For ease of description, Figure 1 The illustrated communication system is described using the example of an access network device as a base station and terminal devices as terminals. It is understood that when the communication system includes an integrated access and backhaul (IAB) network, the base station can be an IAB node. It should be noted that in the embodiments of this application, the base station and the access network device can be interchanged.

[0093] In this application, the base station and the terminal can be fixed or mobile. The base station and the terminal can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted, on water, or in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of the base station and the terminal.

[0094] The roles of base stations and terminals can be relative, for example, Figure 1 The helicopter or drone 120i can be configured as a mobile base station. For terminals 120j accessing the wireless access network 100 via 120i, terminal 120i is a base station. However, for base station 110a, 120i is a terminal; that is, 110a and 120i communicate via a wireless air interface protocol. Of course, 110a and 120i can also communicate via a base station-to-base station interface protocol. In this case, relative to 110a, 120i is also a base station. Therefore, both base stations and terminals can be collectively referred to as communication devices. Figure 1 The 110a and 110b in the text can be referred to as communication devices with base station functions. Figure 1 The 120a-120j in the text can be referred to as communication devices with terminal functions.

[0095] Communication between base stations and terminals, between base stations, and between terminals can be conducted using licensed spectrum, unlicensed spectrum, or both simultaneously. Communication can be achieved using spectrum below 6 GHz, spectrum above 6 GHz, or both simultaneously. The embodiments of this application do not limit the spectrum resources used for wireless communication.

[0096] Figure 2a This is a schematic diagram of a communication system according to an embodiment of this application. Please refer to... Figure 2a The communication system includes user equipment (UE), radio access network (RAN) equipment (or simply access network equipment), access and mobility management function (AMF), user plane function (UPF), unified data management (UDM), network data analytics function (NWDAF), location management function (LMF), policy control function (PCF), or network function (NEF).

[0097] The communication system also includes a sensing function (SF), which can establish connections with other core network functions, such as UPF, AMF, UDM, NWDAF, LMF, PCF, or NEF. The sensing function is responsible for configuring how sensing devices perform sensing measurements or interact with sensing requirements. It can also process sensing data. The sensing device can be either a RAN or a UE, and the sensing data can be, for example, data or information related to sensing measurements.

[0098] In one example, the LMF is used to calculate the location of the terminal device. The SF can store an environmental map, enabling environmental map reconstruction, and it interacts with the LMF to exchange environmental, measurement, and other information.

[0099] The name of the sensing function may change as the communication system evolves. Any functional network element with a name similar to SF can be understood as the SF of this application and is applicable to the methods provided in this application. For example, SF can also be a communication sensing function, sensing management function entity, sensing function network element, sensing network element, sensing server, or other names. This application does not limit the name of SF. The following embodiments mainly use the description of SF to introduce the execution operation of this functional network element. The interaction between SF and RAN or UE can be transmitted through AMF or directly. For example, sensing data acquired by RAN or UE can be transmitted to SF via control plane or user plane. Specifically, user plane can be forwarded from RAN or UE to SF via UPF, or RAN or UE can transmit directly to SF.

[0100] Figure 2b This is another schematic diagram of the communication system in an embodiment of this application. Please refer to... Figure 2b In a communication system, a sensing unit (SU) is added to the access network equipment side. This SU can perform sensing-related functions, including but not limited to: SU interacting with the SF (Sensing Provider Interface) to request sensing data; and SU interacting with core network equipment, the RAN (Radio Router Network), or the UE (User Equipment) to exchange sensing data. The core network equipment may be, for example, an AMF (Academic Management Function) or a UPF (User Member Function). For example, the RAN may include a centralized unit (CU) or a distributed unit (DU).

[0101] In one example, when the UE reports sensing data to the RAN, the sensing data can be passed from the UE to the DU, then from the DU to the CU, and finally from the CU to the SU on the RAN side; or the sensing data can be passed from the UE to the DU and then directly from the DU to the SU; or the UE can directly pass the sensing data to the SU.

[0102] The name of the sensing unit may change as the communication system evolves. Any functional network element with a name similar to SU can be understood as SU in this application and is applicable to the method provided in this application. For example, SU can also be a sensing computing unit, sensing computing module, sensing module, sensing computing board, computing device, or other names. This application does not limit the name of SU.

[0103] The sensing unit can be independent of the access network equipment; for example, it can be deployed in an edge computing device, or it can be an external service board of the access network equipment. Alternatively, the sensing unit can be co-located with the access network equipment, for example, it can be a functional unit or module within the access network equipment.

[0104] The technical solution of this application can be applied to cellular communication systems related to the 3rd Generation Partnership Project (3GPP). For example, 4th generation (4G) communication systems, 5G communication systems, and communication systems beyond the 5th generation. For example, future communication systems. For example, 4th generation communication systems may include Long Term Evolution (LTE) communication systems. 5th generation communication systems may include New Radio (NR) communication systems. The technical solution of this application can also be applied to Wireless Fidelity (WiFi) systems, communication systems supporting the convergence of multiple wireless technologies, device-to-device (D2D) systems, or vehicle-to-everything (V2X) communication systems.

[0105] The following describes the terminal equipment, access network equipment, sensing management function, and positioning management function involved in this application.

[0106] Terminal equipment, also known as user equipment (UE), mobile station (MS), mobile terminal (MT), fixed wireless access (FWA), customer premises equipment (CPE), etc., refers to devices that include wireless communication capabilities (providing voice / data connectivity to users). Examples include handheld devices with wireless connectivity, in-vehicle devices, and machine-type communication (MTC) terminals. Currently, terminal devices can include: mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self-driving (e.g., drones, vehicles), wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, and wireless terminals in smart homes. For example, wireless terminals in self-driving can be drones, helicopters, or airplanes. For example, wireless terminals in vehicle-to-everything (V2X) can be in-vehicle equipment, vehicle-mounted equipment, in-vehicle modules, vehicles, or ships. Wireless terminals in industrial control can be cameras, robots, or robotic arms. Wireless terminals in smart homes can be televisions, air conditioners, robot vacuums, speakers, or set-top boxes. The terminal device can also be a device or module that is connected to the communication system shown above and has corresponding communication functions. The terminal device usually contains a communication module, circuit or chip that performs the corresponding communication function, and the terminal device is also configured with program instructions for performing the corresponding communication function.

[0107] It should be noted that the terminal device can be a device or apparatus with a chip, or a device or apparatus with integrated circuitry, or a chip, chip system, module, or control unit in the device or apparatus shown above; this application does not limit the specific application. It should also be noted that in this application, when referring to a terminal device, it can refer to the terminal device itself, or to the chip, functional module, or integrated circuit within the terminal device that performs the method provided in this application; this application does not limit the specific application. An access network device is an apparatus deployed in a wireless access network to provide wireless communication functions for a terminal device. An access network device can connect a terminal device to a radio access network (RAN) node in a wireless network, and can also be called an access network device, RAN entity, access node, network node, or communication device, etc.

[0108] Specifically, access network equipment can be access network equipment for cellular systems related to the 3rd Generation Partnership Project (3GPP). For example, 4G communication systems, 5G communication systems, or future communication systems. Access network equipment can also be access network equipment in Open RAN (ORAN) or Cloud Radio Access Network (CRAN). Alternatively, access network equipment can also be access network equipment in a communication system resulting from the integration of two or more of the above communication systems.

[0109] Access network equipment includes, but is not limited to: evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home-evolved Node B, or home Node B, HNB), base band unit (BBU), access point (AP) in wireless fidelity (WIFI) systems, macro base station, micro base station, wireless relay node, donor node, radio controller in CRAN scenarios, wireless backhaul node, transmission point (TP), or transmission and reception point (TRP), etc., and can also be access network equipment in 5G mobile communication systems. For example, next-generation NodeBs (gNBs), TRPs, and TPs in NR systems; or antenna panels (including multiple antenna panels) of base stations in 5G mobile communication systems; or, access network equipment can also be network nodes constituting gNBs or transmission points. Examples include centralized units (CUs), distributed units (DUs), centralized unit control planes (CU-CPs), centralized unit user planes (CU-UPs), or radio units (RUs). CUs and DUs can be separate entities or included in the same network element, such as a BBU. RUs can be included in radio equipment or radio units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs). Alternatively, access network equipment can also be servers, wearable devices, vehicles, or in-vehicle equipment. For example, access network equipment in V2X technology can be roadside units (RSUs). It should be understood that the aforementioned TRP can be a device or module located on the network side of the aforementioned communication system and possessing corresponding communication functions. The TRP typically contains a communication module, circuit, or chip that performs the corresponding communication functions. The TRP can also be configured with program instructions for the corresponding communication functions.

[0110] It should be noted that CU (or CU-CP and CU-UP), DU, or RU may have different names in different systems, but those skilled in the art will understand their meaning. For example, in an Open Access Network (ORAN) system, CU can also be called an open centralized unit (O-CU) or an open CU, DU can also be called an open distributed unit (O-DU), CU-CP can also be called an open centralized unit control plane (O-CU-CP), CU-UP can also be called an open centralized unit user plane (O-CU-UP), and RU can also be called an open radio unit (O-RU). This application does not impose any specific limitations on these details. Any of the units CU, 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.

[0111] Optionally, for network elements in the ORAN system, each network element can implement the protocol layer functions shown in Table 1 below.

[0112] Table 1

[0113]

[0114] It should be noted that in the ORAN system, the access network equipment in this application can be one or more network elements listed in Table 1 above.

[0115] The architecture of the CU and DU of the access network equipment is described below. An access network equipment includes at least one CU and at least one DU. Optionally, the access network equipment may also include at least one RU.

[0116] The following example uses an access network device consisting of one CU and one DU. The CU has some core network functions and can include CU-CP and CU-UP. The CU and DU can be configured according to the protocol layer functions of the wireless network they implement. For example, the CU may be configured to implement the Packet Data Convergence Protocol (PDCP) layer and above (e.g., RRC and / or SDAP layers). The DU may be configured to implement protocol layers below the PDCP layer (e.g., RLC, MAC, and / or physical (PHY) layers). Alternatively, the CU may be configured to implement protocol layers above the PDCP layer (e.g., RRC and / or SDAP layers), and the DU may be configured to implement protocol layers below the PDCP layer (e.g., RLC, MAC, and / or PHY layers).

[0117] When a CU includes CU-CP and CU-UP, CU-CP is used to implement the control plane functions of the CU, and CU-UP is used to implement the user plane functions of the CU. For example, when a CU is configured to implement the functions of the PDCP layer, RRC layer, and SDAP layer, CU-CP is used to implement the RRC layer functions and the control plane functions of the PDCP layer, and CU-UP is used to implement the SDAP layer functions and the user plane functions of the PDCP layer.

[0118] The CU-CP can interact with network elements in the core network used to implement control plane functions. These network elements can be access and mobility function (AMF) network elements, such as the AMF in a 5G system. The AMF is responsible for mobility management in the mobile network, such as terminal device location updates, terminal device registration with the network, and terminal device handover.

[0119] CU-UP can interact with network elements in the core network used to implement user plane functions. These network elements, such as the user plane function (UPF) in a 5G system, are responsible for forwarding and receiving data in terminal devices.

[0120] Optionally, the ORAN architecture also includes a RAN Intelligent Controller (RIC) module.

[0121] It should be noted that the access network equipment can be a device or apparatus with a chip, or a device or apparatus with integrated circuits, or a chip, chip system, module, or control unit in the aforementioned device or apparatus; this application does not impose any specific limitation. It should also be noted that in this application, the term "access network equipment" can refer to the access network equipment itself, or to the chip, functional module, or integrated circuit within the access network equipment that performs the method provided in this application; this application does not impose any specific limitation.

[0122] Secondly, some technical concepts involved in the embodiments of this application will be introduced.

[0123] 1. The terms "system" and "network" in the embodiments of this application can be used interchangeably. "Multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that there can be three relationships. 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 related objects before and after 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, and C" includes A, B, C, AB, AC, BC, or ABC. And, unless otherwise specified, the ordinal numbers such as "first" and "second" mentioned in the embodiments of this application are used to distinguish multiple objects and are not used to limit the order, sequence, priority, or importance of multiple objects.

[0124] 2. In the embodiments of this application, "send" and "receive" indicate the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX, which may include sending directly via the air interface or sending indirectly via the air interface from other units or modules. "Receive information from YY" can be understood as the source of the information being YY, which may include receiving directly from YY via the air interface or receiving indirectly from YY via the air interface from other units or modules. "Send" can also be understood as the "output" of the chip interface, and "receive" can also be understood as the "input" of the chip interface.

[0125] In other words, sending and receiving can occur between devices, such as between network devices and terminal devices, or within a device, such as between components, modules, chips, software modules, or hardware modules within the device via buses, wiring, or interfaces.

[0126] It is understandable that information may undergo necessary processing, such as encoding and modulation, between the source and destination, but the destination can understand the valid information from the source. Similar statements in this application can be interpreted in a similar way and will not be elaborated further.

[0127] 3. In the embodiments of this application, "instruction" can include direct instruction and indirect instruction, as well as explicit instruction and implicit instruction. The information indicated by a certain piece of information (as described below, the instruction information) is called the information to be instructed. In the specific implementation process, there are many ways to indicate the information to be instructed, such as, but not limited to, directly indicating the information to be instructed, such as the information to be instructed itself or its index. It can also indirectly indicate the information to be instructed by indicating other information, where there is an association between the other information and the information to be instructed; or it can only indicate a part of the information to be instructed, while the other parts are known or pre-agreed upon. For example, the instruction can be implemented by using a pre-agreed (e.g., protocol predefined) arrangement of various information, thereby reducing the instruction overhead to a certain extent. This application does not limit the specific method of instruction. It is understood that for the sender of the instruction information, the instruction information can be used to indicate the information to be instructed; for the receiver of the instruction information, the instruction information can be used to determine the information to be instructed.

[0128] 4. Environment and environmental information.

[0129] The environment can also be referred to as the scene. In the embodiments of this application, the environment refers to the environment in which the transmitter or receiver is located (or situated). The environment in which the transmitter is located can be an environment determined with the transmitter's position as a reference point; similarly, the environment in which the receiver is located can be understood as an environment determined with the receiver's position as a reference point. In fact, both the environment in which the transmitter and the environment in which the receiver are located can include the transmitter and the receiver. The environment can be used to assist in locating the transmitter and the receiver. In addition to the transmitter and the receiver, the scene can also include obstacles.

[0130] Information used to indicate the environment is called environmental information. Environmental information can also be called environmental parameter information, or environmental parameter set information, etc. Environmental information indicates the environment in which the transmitter or receiver is located. Environmental information indicates obstacles in the environment. Environmental information includes at least one of the following: the number of obstacles, their location, shape, or material properties. The content of obstacles can refer to the obstacle content discussed above; repeated descriptions will not be listed again. Optionally, environmental information indicates at least one of the following: the outline and material of buildings / vegetation, the outline and location of vehicles, the location of pedestrians, or the distribution of crowds.

[0131] Environmental information can take the form of environmental map information or environmental point cloud information (such as two-dimensional, three-dimensional, or higher-dimensional point cloud information). Map information, such as a building map, can contain the coordinates of multiple edges of buildings, thus indicating the location, shape, and size of obstacles in the environment. Three-dimensional point cloud information includes, for example, a large number of points, each containing a three-dimensional coordinate and other attributes, such as point cloud intensity information or point cloud type information, indicating the object type (or material) corresponding to the point cloud.

[0132] 5. Environmental perception.

[0133] 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.

[0134] In the field of environmental sensing, traditional methods typically rely on specialized sensors and equipment, such as cameras, radar, or infrared detectors. However, these methods have several drawbacks, including high cost, difficult deployment, and susceptibility to weather conditions. In contrast, utilizing base stations for environmental sensing offers numerous advantages.

[0135] Base stations offer extensive coverage. As the infrastructure of wireless communication networks, base stations typically cover entire cities or specific areas. This means that using base stations for environmental sensing enables real-time monitoring of large areas, providing valuable data support for urban planning, traffic management, disaster early warning, and other fields. Secondly, base stations are continuously online. They need to provide communication services to users 24 hours a day, so they are always operational. This allows for real-time, continuous data collection and analysis for environmental sensing, enabling timely detection and handling of environmental problems. Furthermore, using base stations for environmental sensing can reduce costs. Since base stations are already widely deployed in cities, there is no need to install a large number of additional sensors and equipment. Simply upgrading and modifying existing base stations is sufficient to achieve environmental sensing and monitoring. This not only saves significant investment costs but also avoids redundant construction and resource waste.

[0136] 6. Sensing technology.

[0137] Sensing technology refers to the use of communication networks to detect, track, and image obstacles. The underlying principles of sensing technology differ somewhat from those of communication technology. Communication technology involves the transmitter modulating information onto radio waves and sending it to the receiver, which then demodulates the signal to obtain the information. Sensing technology, however, requires the transmitter to send radio waves in a specific direction. When these radio waves strike the surface of an obstacle, they are reflected, and the receiver receives and processes these reflected waves to obtain information such as the obstacle's shape, size, location, material, speed, and type.

[0138] Sensing technology can generally be divided into two types based on its mode: single-station sensing and dual-station sensing. In single-station sensing, the transmitting and receiving ends of the measurement signal are the same device. In terms of the measurement signal flow, the sensing station must both send the measurement signal and receive the signal reflected from the surface of the obstacle (also known as the echo signal). Therefore, the single-station sensing mode is also called the self-transmitting and self-receiving mode.

[0139] like Figure 3a As shown, Figure 3a This is a schematic diagram of a single-station sensing scenario. In dual-station sensing, the transmitting and receiving ends of the measurement signal are two different devices. From the signal flow perspective, after sensing station A transmits the measurement signal, the signal reflected from the obstacle surface is received by sensing station B. Therefore, the dual-station sensing mode is also called the A-transmit B-receive mode, as follows: Figure 3b As shown, Figure 3b This is a schematic diagram of a dual-station sensing scenario.

[0140] For easier understanding, please refer to Figure 3c , Figure 3c This is a schematic diagram of a perception scene in an embodiment of this application. Figure 3c During the communication process between the access network device and the terminal device, the access network device can also sense objects that do not have communication capabilities, such as... Figure 3c The cars and users in the middle.

[0141] Furthermore, Figure 3c The illustrated perceptual scene can be further subdivided into multiple sub-scenes. For example... Figure 3d The illustrated sensing scenario uses the access network device as a base station and the terminal device as a user equipment (UE) as an example. Figure 3dThis is a schematic diagram of another sensing scenario in the embodiments of this application. The sensing scenario may specifically include: (1) the base station sends a measurement signal and receives the echo signal of the measurement signal; (2) the UE sends a measurement signal and receives the echo signal of the measurement signal; (3) base station A sends a measurement signal and base station B receives the echo signal of the measurement signal, and base station A and base station B are different base stations; (4) UE A sends a measurement signal and UE B receives the echo signal of the measurement signal, and UE A and UE B are different UEs; (5) the base station sends a measurement signal and the UE receives the echo signal of the measurement signal; (6) the UE sends a measurement signal and the base station receives the echo signal of the measurement signal.

[0142] In this embodiment, the coverage area of ​​the sensing signal is referred to as the sensing signal partition, sensing signal region, sensing cell, or sensing area; correspondingly, the coverage area of ​​the communication signal is referred to as the communication signal partition or communication cell. Currently, each communication cell only configures sensing resources for the communication devices within its own cell; these sensing resources refer to the resources for receiving and / or transmitting sensing signals.

[0143] However, the applicant's research revealed that the coverage area of ​​sensing signals is typically larger than that of communication signals. For example, in low-altitude sensing scenarios, since there are usually no obstacles obstructing the view, the coverage area of ​​sensing signals is greater than that of communication signals. Therefore, the sensing area and the communication cell may not be the same. How to configure sensing resources for communication devices when the sensing area and the communication cell are inconsistent becomes a pressing issue.

[0144] Based on this, this application proposes a resource configuration method, which includes: a first device sending first configuration information, the first configuration information being used to configure first sensing resources, the first sensing resources being used by a second device within a first sensing area to receive and / or transmit sensing signals, the first sensing area including one or more communication cells. Since the first sensing area includes one or more communication cells, second devices in one or more communication cells within the first sensing area can all receive and / or transmit sensing signals based on the first sensing resources to achieve sensing. This solves the problem of how to configure sensing resources for the second device when the sensing area and the communication cells are inconsistent.

[0145] Before introducing the method embodiments proposed in this application, the communication system involved in the embodiments of this application will be introduced first.

[0146] Please see Figure 4a , Figure 4aThis is a schematic diagram of a communication system according to an embodiment of this application. The communication system includes a first device, a second device, and a third device, wherein the third device is used to configure the association between a sensing area and a communication cell to the first device and / or the second device, the first device is used to configure sensing resources to the second device, the second device is located within the sensing area, and the second device receives and / or transmits sensing signals based on the sensing resources.

[0147] Combination Figure 4a Next, we will introduce some possible implementations of the communication system in the embodiments of this application.

[0148] In one possible implementation, please refer to Figure 4b , Figure 4b This is a schematic diagram of another communication system in an embodiment of this application. In this communication system, the third device can be SF or SU, the first device can be RAN, and the second device can be UE.

[0149] For another possible implementation, please refer to [link / reference]. Figure 4c , Figure 4c This is a schematic diagram of another communication system according to an embodiment of this application. In this communication system, the third device can be an SF or SU, the first device can be a first RAN, and the second device can be a second RAN. In other words, the first device and the second device are independent of each other, namely the first RAN and the second RAN. The first RAN configures a first sensing resource to the second RAN, so that the second RAN receives and / or transmits sensing signals based on the first sensing resource. Alternatively, the first RAN sends first configuration information to the second RAN, so that the second RAN bypasses the first sensing resource when configuring sensing resources or reference signal resources for the UE. The reference signal resource refers to the resource used by the UE when receiving and / or transmitting the reference signal. Since the communication cells managed by the first RAN and the cells managed by the second RAN are different, interference between neighboring cells can be avoided by the above method.

[0150] For another possible implementation, please refer to [link / reference]. Figure 4d , Figure 4d This is a schematic diagram of another communication system according to an embodiment of this application. In this communication system, the third device can be SF or SU, the first device can be CU, and the second device can be DU or UE. In other words, the CU can configure a first sensing resource to the DU, so that the DU receives and / or transmits sensing signals based on the first sensing resource; the CU can also configure a first sensing resource to the UE, so that the UE receives and / or transmits sensing signals based on the first sensing resource. The CU can directly configure the first sensing resource to the UE, or the CU can configure the first sensing resource to the UE through the DU.

[0151] For another possible implementation, please refer to [link / reference]. Figure 4e , Figure 4e This is a schematic diagram of another communication system according to an embodiment of this application. In this communication system, the third device can be SF, the first device can be SU, and the second device can be CU, DU, or UE. In other words, SU can configure a first sensing resource to CU, DU, or UE, so that DU or UE receives and / or transmits sensing signals based on the first sensing resource; after SU configures the first sensing resource to CU, CU can also further configure the first sensing resource to DU or UE, so that DU or UE receives and / or transmits sensing signals based on the first sensing resource.

[0152] Based on the aforementioned communication system, the resource configuration method proposed in this application will be introduced next.

[0153] Please see Figure 5 , Figure 5 This is a schematic flowchart illustrating an embodiment of a resource allocation method according to this application. The resource allocation method proposed in this application includes:

[0154] S1-1, The third device sends second configuration information to the first device, and the second configuration information indicates the first sensing area.

[0155] In step S1-1, the third device sends second configuration information to the first device, which indicates the first sensing area. In this embodiment, the first sensing area can also be replaced by: a first sensing range, a first sensing cell, a first sensing supercell, or a first sensing signal coverage area; this embodiment does not limit this.

[0156] Optionally, the second configuration information can also be used to indicate that the first sensing area is associated with one or more communication cells, or the second configuration information can also be used to indicate that one or more communication cells belong to the first sensing area.

[0157] The second configuration information includes one or more of the following: identification information of the first sensing area, or identification information of one or more communication cells.

[0158] The following section uses the example of the first device managing communication cell 0, communication cell 1, and communication cell 2 to illustrate how the first device determines the association between the first sensing area and the communication cell based on the second configuration information.

[0159] In one possible implementation, the second configuration information includes identification information of the first sensing area. The first device determines, based on the second configuration information, that communication cell 0, communication cell 1, and communication cell 2 are associated with the first sensing area, and that communication cell 0, communication cell 1, and communication cell 2 belong to the first sensing area.

[0160] In another possible implementation, the second configuration information includes identification information for multiple first sensing areas and identification information for one or more communication cells associated with each first sensing area. For example, the second configuration information indicates that first sensing area 1 is associated with communication cell 0, and the second configuration information indicates that first sensing area 2 is associated with both communication cell 1 and communication cell 2. The first device determines, based on this second configuration information, that first sensing area 1 is associated with communication cell 0, and first sensing area 2 is associated with both communication cell 1 and communication cell 2. For ease of understanding, please refer to Table 2, which is an illustration of the second configuration information.

[0161] Table 2

[0162]

[0163] Table 2 illustrates the second configuration information, indicating that the first sensing area 1 is associated with communication cell 0, and that the first sensing area 2 is associated with both communication cell 1 and communication cell 2.

[0164] In another example, the second configuration information can be represented as "({0}, {0, 1, 2}) and ({3}, {3, 4, 5})", where "{0}" is the identification information of the first sensing area 1, "{0, 1, 2}" indicates the communication cell 0, communication cell 1 and communication cell 2 corresponding to the first sensing area 1, and the identification information of communication cell 0 among communication cell 0, communication cell 1 and communication cell 2 is selected as the identification information of the first sensing area 1, "{3}" is the identification information of the first sensing area 2, and "{3, 4, 5}" indicates the communication cell 3, communication cell 4 and communication cell 5 corresponding to the first sensing area 2, and the identification information of communication cell 3 among communication cell 3, communication cell 4 and communication cell 5 is selected as the identification information of the first sensing area 2.

[0165] In another possible implementation, the second configuration information includes identification information of one or more communication cells. The first device determines one or more communication cells associated with the first sensing area based on the second configuration information. After receiving second configuration information, the first device allocates a first sensing area to the one or more communication cells indicated by the second configuration information, thus associating the one or more communication cells with the first sensing area. For example, if second configuration information #1 indicates communication cells 0, 1, and 2, then the first device determines that the communication cells associated with the first sensing area 1 are communication cells 0, 1, and 2 based on second configuration information #1. If second configuration information #2 indicates communication cells 3, 4, and 5, then the first device determines that the communication cells associated with the first sensing area 2 are communication cells 3, 4, and 5 based on second configuration information #2.

[0166] Optionally, after step S1-1, the first device may forward the second configuration information to the second device.

[0167] In one example, the relationship between the communication cell and the sensing area is as follows: Figure 6 As shown.

[0168] Figure 6 This is a schematic diagram of a sensing area in an embodiment of this application. Access network device 1 manages communication cells 1-0, 1-1, and 1-2, and during network planning, classifies communication cells 1-0, 1-1, and 1-2 into the same sensing area 1. Access network device 2 manages communication cells 2-0, 2-1, and 2-2, and during network planning, classifies communication cells 2-0, 2-1, and 2-2 into the same sensing area 2. Access network device 3 manages communication cells 3-0, 3-3, and 3-2, and during network planning, classifies communication cells 3-0, 3-3, and 3-2 into the same sensing area 3. Taking access network device 1 as the first device, the terminal device in communication cell 1-0 as the second device, and the SF managing access network device 1 as the third device as an example, the SF sends second configuration information to access network device 1. This second configuration information indicates that sensing area 1 is associated with communication cells 1-0, 1-1, and 1-2.

[0169] In another example, multiple communication cells managed by the same access network device can be divided into multiple sensing areas. For example, access network device 1 manages communication cells 1-0, 1-1, and 1-2. Among them, communication cells 1-0 and 1-1 are divided into sensing area 1, and communication cell 1-2 is divided into sensing area 2.

[0170] In another example, the multiple communication cells included in the sensing area can belong to different access network devices. For example, access network device 1 manages communication cells 1-0, 1-1, and 1-2, while access network device 2 manages communication cells 2-0, 2-1, and 2-2. Communication cells 1-0 and 1-1 are classified as sensing area 1, communication cells 1-2, 2-0, and 2-1 are classified as sensing area 2, and communication cell 2-2 is classified as sensing area 3.

[0171] S1-2, The third device sends the second configuration information to the second device.

[0172] In steps S1-2, the third device can also directly send the second configuration information to the second device.

[0173] The execution order of steps S1-1 and S1-2 is not limited in this embodiment of the application.

[0174] Steps S1-1 and / or S1-2 are optional. For example, when step S1-1 is executed, step S1-2 may not be executed. Or, for example, neither step S1-1 nor step S1-2 may be executed.

[0175] S2. The first device sends first configuration information to the second device. The first configuration information is used to configure the first sensing resources. The first sensing resources are used by the second device within the first sensing area to receive and / or send sensing signals. The first sensing area includes one or more communication cells.

[0176] In step S2, the first device sends first configuration information to the second device. This first configuration information is used to configure first sensing resources. The first sensing resources are used by the second device within the first sensing area to receive and / or transmit sensing signals. In this embodiment, sensing resources refer to the resources used by the second device within the sensing area to receive and / or transmit sensing signals; sensing resources can also be called sensing signal resources.

[0177] Specifically, the first configuration information is used to configure the time-domain resource location, the frequency-domain resource location, and / or the antenna port used by the first sensing resource. The time-domain resource location of the first sensing resource can also be referred to as the time-domain resource used by the sensing signal within the first sensing area, or the time-domain resource occupied by the first sensing resource. The frequency-domain resource location of the first sensing resource can also be referred to as the frequency-domain resource used by the sensing signal within the first sensing area, or the frequency-domain resource occupied by the first sensing resource. The antenna port used by the first sensing resource can also be referred to as the spatial resource used by the sensing signal within the first sensing area, or the spatial resource occupied by the first sensing resource. The first configuration information is also used to configure the code-domain resource location of the first sensing resource, which can also be referred to as the code-domain resource used by the sensing signal within the first sensing area.

[0178] Optionally, the first configuration information may include identification information of the first sensing area, so that the second device can determine the sensing area corresponding to the first sensing resource based on the first configuration information. The second device can determine one or more communication cells associated with the first sensing area based on the identification information of the first sensing area and the second configuration information.

[0179] Optionally, the first configuration information may include identification information of one or more communication cells, so that the second device can determine the communication cells to which the first sensing resource applies based on the first configuration information. The second device can determine the first sensing area associated with the one or more communication cells based on the identification information of the one or more communication cells and the second configuration information.

[0180] Optionally, when the first configuration information includes the identification information of the first sensing area and the identification information of one or more communication cells, the second device can determine the first sensing area and one or more communication cells associated with the first sensing area based on the first configuration information.

[0181] Optionally, the first configuration information may not include the identification information of the first sensing area and / or the identification information of one or more communication cells. The first device needs to notify the second device in advance of the first sensing area and / or one or more communication cells corresponding to the first sensing resource.

[0182] The following section details the specific content of the first configuration information.

[0183] The first configuration information indicates one or more of the following: the frequency band included in the first sensing resource, or the frequency band carrying the sensing signal, wherein the sensing signal refers to the sensing signal received and / or transmitted by the second device within the first sensing area; the subcarrier included in the first sensing resource, or the subcarrier carrying the sensing signal; the resource block (RB) included in the first sensing resource, or the resource block RB carrying the sensing signal; the resource element (RE) included in the first sensing resource, or the resource element RE carrying the sensing signal; or the RE pattern included in the first sensing resource, or the RE pattern carrying the sensing signal, wherein the RE pattern includes one or more REs; or the sequence used by the first sensing resource and / or the index number of the sequence. The RE pattern carrying the sensing signal may also be referred to as the RE pattern carrying the sensing signal or the basic pattern of the sensing signal, and the embodiments of this application do not limit this.

[0184] For example, the first configuration information includes: the starting RB of the first sensing resource and the number of RBs occupied by the first sensing resource, and the frequency domain resources of the first sensing resource are determined based on the starting RB and the number of RBs.

[0185] In another example, the first configuration information may not explicitly indicate the frequency domain resource location of the first sensing resource. In this case, the first device or the second device determines the frequency domain resource location of the first sensing resource based on the first configuration information by including the bandwidth part (BWP) currently activated by the first device or the second device.

[0186] In another example, when the first configuration information indicates the resource block carrying the sensing signal, the first configuration information may further include: the RE modes included in the resource block, or one or more RE modes carrying the sensing signal. The RE modes include, but are not limited to: no code division multiplexing (noCDM), frequency domain code division multiplexing 2 (fd-CDM2), or code division multiplexing 4-frequency domain 2-time domain 2 (cdm4-FD2-TD2), etc. Optionally, the first configuration information may further include: the RE mode density included in each resource block carrying the sensing signal, where the RE mode density indicates the number of RE modes included in each resource block, for example: 0.5, 1, or 3, etc.

[0187] The first configuration information may also indicate: the spatial resources included in the first sensing resource, or the spatial resources carrying the sensing signal, or the antenna port carrying the sensing signal, or the antenna port used by the first sensing resource. For example, 1, 2, or 4, wherein, in order to obtain aperture gain, the first sensing resource using 2 antenna ports can be antenna ports arranged at any two corners of a two-dimensional (2D) antenna panel, and the first sensing resource using 4 antenna ports can be antenna ports arranged at the four corners of a 2D antenna panel.

[0188] The first configuration information may also indicate one or more of the following: the time slot carrying the sensing signal, the symbol carrying the sensing signal, or the subframe carrying the sensing signal. For example, the first configuration information includes: the index of the first symbol occupied by the first sensing resource within the time slot where the symbol is located. As another example, the first configuration information includes: the index of the starting symbol occupied by the sensing signal, and / or, the number of symbols occupied by the sensing signal.

[0189] Optionally, since the first sensing resource can be a periodic resource, the first configuration information can also indicate the period and time slot offset of the first sensing resource. For example, the first configuration information includes: one or more time slots, and a time slot offset indicating the time slot carrying the sensing signal.

[0190] For example, the sequence used by the first sensing resource includes, but is not limited to: m-sequences, gold sequences, or Zadoff-Chu (ZC) sequences.

[0191] S3. The second device determines the first sensing resource based on the first configuration information.

[0192] In step S3, the second device determines the first sensing resource according to the first configuration information, including: the second device determines the first sensing area corresponding to the first sensing resource according to the first configuration information, determines the communication cell corresponding to the first sensing resource according to the first configuration information, determines the time domain resource location of the first sensing resource, the frequency domain resource location of the first sensing resource, and / or the antenna port of the first sensing resource according to the first configuration information.

[0193] In one example scenario, when the second device is a terminal device, during a cell handover, if the source and destination cells belong to the same sensing area (i.e., the terminal device's sensing area does not change), the terminal device reuses the sensing resources configured in the source sensing cell. If the source and destination cells belong to different sensing areas, the terminal device switches from the sensing area of ​​the source cell to the sensing area of ​​the destination cell. The terminal device can proactively request the first device in the destination cell to retransmit the first configuration information, and the first device in the destination cell can proactively retransmit the first configuration information.

[0194] Optionally, when the second device is a terminal device, during the handover process of a communication cell, if the access network equipment of the source communication cell is different from the access network equipment of the destination communication cell (e.g., the source communication cell is the first access network equipment, and the destination communication cell is the second access network equipment), the first access network equipment can send its own first configuration information to the second access network equipment. Alternatively, the terminal device can proactively report the first configuration information of the first access network equipment after handover to the second access network equipment, or the core network equipment can notify the second access network equipment of the terminal device's first configuration information in the source communication cell. After obtaining the first configuration information of the first access network equipment, the second access network equipment can perform the following processing:

[0195] Processing Method A: The second access network device determines its own first configuration information based on the first configuration information of the first access network device, and then allocates the first configuration information of the second access network device to the terminal device. For example, if the source communication cell and the target communication cell belong to different sensing areas, the second access network device allocates new sensing resources to the terminal device using its own first configuration information.

[0196] Processing Method B: Based on the first configuration information of the first access network device, the second access network device determines that the source communication cell and the target communication cell belong to the same sensing area. The second access network device may not need to send its first configuration information to the terminal device; the terminal device can directly reuse the sensing resources of the source communication cell according to the configured first configuration information of the first access network device. Alternatively, the second access network device may explicitly instruct the terminal device to reuse the sensing resources of the source communication cell in the target communication cell.

[0197] In another example scenario, the first device can be a first access network device, and the second device can be a second access network device. Specifically, the first device sending the first configuration information to the second device can be the first access network device sending the first configuration information to the second access network device. The first access network device corresponds to a first sensing area, and the second access network device corresponds to a second sensing area, which are different from each other. Therefore, the second access network device performs resource scheduling based on the first configuration information. When allocating resources to terminal devices within the second sensing area, the second access network device can bypass the first sensing resources, reducing interference between cells.

[0198] S4. The second device receives and / or transmits sensing signals based on the first sensing resource.

[0199] In step S4, after the second device determines the first sensing resource, the second device receives and / or sends sensing signals based on the first sensing resource.

[0200] Optionally, the second device can determine sensing information based on the sensing signal. This sensing information can also be called sensing imaging information. The algorithm includes, but is not limited to, back projection (BP) or discrete Fourier transform (DFT). In one example, the sensing information can be a three-dimensional power spectrum in a distance-horizontal-vertical angle coordinate system with the terminal device or access network device as the origin. This three-dimensional power spectrum includes the power values ​​of all locations within the sensing range of the network device. Specifically, each location corresponds to a distance parameter, a horizontal angle parameter, a vertical angle parameter, and a power value. The higher the power value, the stronger the reflected or scattered energy of the sensing signal at that location, and the higher the probability that a sensing target exists at that location; conversely, the lower the power value, the lower the reflected or scattered energy of the sensing signal at that location, and the lower the probability that a sensing target exists at that location.

[0201] The following is combined Figure 3d The perception scenario shown illustrates some application scenarios involved in the embodiments of this application.

[0202] by Figure 3d Taking a sensing scenario (1) as an example, in one example scenario, the second device is a base station. The base station (second device) determines a first sensing area and one or more communication cells associated with the first sensing area based on the second configuration information configured by the third device, such as a sensing function or other core network equipment. The base station (second device) determines a first sensing resource corresponding to the first sensing area based on the first configuration information configured by the first device, such as a sensing unit or other base station. The base station (second device) receives and / or transmits sensing signals based on the first sensing resources.

[0203] by Figure 3d Taking the mid-sensing scenario (2) as an example, in one example scenario, the second device is a UE. The UE determines the first sensing area and one or more communication cells associated with the first sensing area based on the second configuration information configured by the third device, such as a sensing function or other core network equipment. The UE (second device) determines the first sensing resource corresponding to the first sensing area based on the first configuration information configured by the first device, such as a base station or sensing unit. The UE receives and / or transmits sensing signals based on the first sensing resource.

[0204] by Figure 3d Taking the sensing scenario (3) as an example, in one example scenario, the second device includes base station A and base station B. Base station A and base station B determine the first sensing area and one or more communication cells associated with the first sensing area according to the second configuration information configured by the third device. The third device is, for example, a sensing function or other core network equipment. Base station A and base station B determine the first sensing resource corresponding to the first sensing area according to the first configuration information configured by the first device. The first device is, for example, a sensing unit or base station C. Base station C, base station A, and base station B all belong to the first sensing area. Base station A sends a sensing signal to base station B according to the first sensing resource, or base station A receives a sensing signal sent by base station B according to the first sensing resource.

[0205] by Figure 3d Taking the sensing scenario (4) as an example, in one example scenario, the second device includes UE A and UE B. UE A and UE B determine the first sensing area and one or more communication cells associated with the first sensing area according to the second configuration information configured by the third device. The third device may be a sensing function or other core network equipment. UE A and UE B determine the first sensing resource corresponding to the first sensing area according to the first configuration information configured by the first device. The first device may be a sensing unit, a base station, or UE C. UE C, UE A, and UE B all belong to the first sensing area. UE A sends a sensing signal to UE B according to the first sensing resource, or UE A receives a sensing signal sent by UE B according to the first sensing resource.

[0206] by Figure 3d Taking the mid-sensing scenario (5) as an example, in one example scenario, the second device includes a UE and a base station. The UE and the base station determine a first sensing area and one or more communication cells associated with the first sensing area based on the second configuration information configured by the third device, such as a sensing function or other core network equipment. The UE determines the first sensing resource corresponding to the first sensing area based on the first configuration information configured by the first device, such as a sensing unit or a base station. The base station determines the first configuration information itself, and then determines the first sensing resource. The base station sends a sensing signal to the UE based on the first sensing resource, or the UE receives the sensing signal sent by the base station based on the first sensing resource.

[0207] by Figure 3d Taking the sensing scenario (6) as an example, in one example scenario, the second device includes a UE and a base station. The UE and the base station determine a first sensing area and one or more communication cells associated with the first sensing area based on the second configuration information configured by the third device, such as a sensing function or other core network equipment. The UE determines the first sensing resource corresponding to the first sensing area based on the first configuration information configured by the first device, such as a sensing unit or a base station. The base station determines the first configuration information itself, and then determines the first sensing resource. The UE sends a sensing signal to the base station based on the first sensing resource, or the base station receives the sensing signal sent by the UE based on the first sensing resource.

[0208] In the above technical solution, since the first sensing area includes one or more communication cells, the second devices in one or more communication cells within the first sensing area can all receive and / or transmit sensing signals based on the first sensing resources to achieve sensing. This solves the problem of configuring sensing resources when the sensing area and the communication cells are inconsistent. In scenarios where the terminal device switches between different communication cells within the same sensing area, the terminal device can reuse the same sensing resources, avoiding redundant configuration of sensing resources and saving communication overhead.
