Description

Technical Field

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

[0002] Wireless sensing technology can obtain the characteristics of the signal propagation space by analyzing the changes in wireless signals during propagation, thereby enabling scene perception. Taking radar as an example, its basic principle is: the transmitter emits a specific waveform signal, which is transmitted to the receiver through a wireless channel. By combining the transmitted and received signals, the target of interest in the wireless channel can be extracted, thus achieving wireless sensing.

[0003] Wireless communication can be used to send and receive information between two ends. Its basic principle includes: the transmitter transmits a specific waveform signal, which is received by the receiver after passing through the wireless channel. The receiver processes the signal and demodulates the signal transmitted by the transmitter.

[0004] From the perspective of transmitting, receiving, and transmitting signals, wireless communication and wireless sensing are remarkably similar. Therefore, combining wireless communication and wireless sensing allows for simultaneous communication between the transmitting and receiving ends while simultaneously sensing the surrounding environment. Specifically, sensing signals can be transmitted in the frequency domain, which can be used to carry information exchanged between the transmitting and receiving ends, as well as to sense objects in the surrounding environment.

[0005] How to achieve this requires further research. Summary of the Invention

[0007] In a first aspect, embodiments of this application provide a communication method that can be applied to a first device. Optionally, the first device may be a terminal, or a device applicable to a terminal (e.g., a module, a communication module, a circuit or chip responsible for communication and / or sensing functions (such as a modem chip, also known as a baseband chip, or a system-on-chip (SoC) chip or system-in-package (SIP) chip containing a modem core), a chip system, or a processor), or a logical node, logical module, or software capable of implementing all or part of the terminal functions.

[0008] The method may include: a first device receiving configuration information, which can be used to configure a first quasi-co-location relationship, wherein the first quasi-co-location relationship may be a quasi-co-location relationship for sensing between a first antenna port and a second antenna port. The first device receives a first reference signal and a second reference signal. The first reference signal is a reference signal transmitted through the first antenna port; the second reference signal is a reference signal transmitted through the second antenna port. The first and second reference signals can be used for sensing based on the first quasi-co-location relationship.

[0009] Optionally, the quasi-co-location relationship for sensing between the first antenna port and the second antenna port can be replaced by: the quasi-co-location relationship for sensing between the first reference signal and the second reference signal.

[0010] This method defines (or introduces) a first quasi-co-location relationship for sensing among multiple antenna ports. In this way, the sensing measurement results corresponding to the multiple antenna ports can be used for sensing based on the first quasi-co-location relationship, thereby improving sensing performance.

[0016] Optionally, the non-overlapping spatial beams of the first and second antenna ports can be defined as follows: the non-overlapping beams of the first and second antenna ports within a beamwidth range corresponding to x dB. In other words, when the beams of the two antenna ports do not overlap within a beamwidth range corresponding to x dB, the beams of these two antenna ports can be understood as spatially non-overlapping, and the quasi-co-location relationship used for sensing between these two antenna ports can be a first-type quasi-co-location relationship. Here, x is a positive number. For example, x is 3.

[0017] With this design, when the first quasi-co-location relationship is of the first type of quasi-co-location relationship, the reference signal transmitted by the first antenna port and the reference signal transmitted by the second antenna port can be used to sense different targets respectively.

[0018] Based on the first or second aspect, in one possible design, the first quasi-co-location relationship can be a second type of quasi-co-location relationship. The second type of quasi-co-location relationship may include: the beams corresponding to the first antenna port and the beams corresponding to the second antenna port spatially overlapping.

[0019] Optionally, the spatial overlap of the beams corresponding to the first antenna port and the second antenna port may include: the overlap of the beams corresponding to the first antenna port and the second antenna port within a beamwidth range corresponding to x dB. In other words, when the beams corresponding to the two antenna ports overlap within a beamwidth range corresponding to x dB, the beams corresponding to these two antenna ports can be understood as spatially overlapping, and the quasi-co-location relationship used for sensing between these two antenna ports can be a second type of quasi-co-location relationship.

[0020] With this design, when the first quasi-co-location relationship is the second type of quasi-co-location relationship, the reference signals transmitted by multiple antenna ports can be used to sense the same target, and the sensing measurement results corresponding to multiple antenna ports can be used for joint sensing. Compared with sensing through the sensing measurement results corresponding to a single port, this method can improve sensing performance, for example, it can improve sensing accuracy and / or precision.

[0023] Based on the first or second aspect, in one possible design, when the first quasi-co-location relationship is a second type of quasi-co-location relationship, the method may further include: a first device transmitting second information; correspondingly, a second device receiving the second information. The second information is used to indicate a first sensing measurement result and a second sensing measurement result, where the first sensing measurement result is the sensing measurement result corresponding to a first reference signal, and the second sensing measurement result is the sensing measurement result corresponding to a second reference signal. Through this design, the second device can accurately determine the first sensing measurement result and the second sensing measurement result based on the second information.

Thus, the second device can determine the antenna port corresponding to the sensing measurement result and / or the phase corresponding to the antenna port based on the second information, thereby enabling the merging of sensing measurement results corresponding to multiple antenna ports. This improves sensing performance compared to sensing based on the sensing measurement result corresponding to a single port.

[0029] Optionally, the third sensing measurement result is obtained by coherently merging the first sensing measurement result and the second sensing measurement result, which may include: the third sensing measurement result is obtained by performing phase compensation on the first sensing measurement result and the second sensing measurement result, and performing a first processing on the phase-compensated first sensing measurement result and the second sensing measurement result; correspondingly, the first device may perform phase compensation on the first sensing measurement result and the second sensing measurement result, and perform a first processing on the phase-compensated first sensing measurement result and the second sensing measurement result to obtain the third sensing measurement result.

[0030] For example, the first processing is one of the following: averaging, weighted averaging, maximum a posteriori probability processing, or maximum likelihood probability processing.

[0031] This design allows the third sensing measurement result to be obtained by coherently combining the first and second sensing measurement results, thereby improving sensing performance. In some examples, when the first and second antenna ports occupy different frequency domain resources, coherently combining the first and second sensing measurement results can reduce the grating lobes in ranging, increase the unambiguous ranging range, and improve the signal-to-noise ratio (SNR). For example, when coherently combining the ranging results corresponding to P antenna ports, the SNR can be improved by approximately P times. In other examples, when the first and second antenna ports occupy different time domain resources, coherently combining the first and second sensing measurement results can reduce the grating lobes in velocity measurement, increase the unambiguous velocity measurement range, and improve the SNR. For example, when coherently combining the velocity measurement results corresponding to P antenna ports, the SNR can be improved by approximately P times.

Through this implementation, the first device can accurately determine the reporting method of the sensing measurement results based on the configuration information from the second device.

[0033] Based on the first or second aspect, in one possible design, the third information is also used to indicate that the reported sensing measurement results are obtained by coherently combining the sensing measurement results corresponding to the first antenna port and the sensing measurement results corresponding to the second antenna port. In this way, the second device can accurately determine the reporting method of the sensing measurement results based on the third information.

[0034] Based on the first or second aspect, in one possible design, when the first quasi-colocation relationship is a second type of quasi-colocation relationship, the method may further include: a first device sending fourth information; correspondingly, a second device receiving the fourth information. The fourth information is used to indicate a fourth sensing measurement result, which is obtained by incoherently merging the first sensing measurement result and the second sensing measurement result; correspondingly, the first device may perform incoherent merging processing on the first sensing measurement result and the second sensing measurement result to obtain the fourth sensing measurement result.

[0035] Optionally, the fourth sensing measurement result is obtained by incoherently merging the first sensing measurement result and the second sensing measurement result, which may include: the fourth sensing measurement result is obtained by calibrating the first sensing measurement result and the second sensing measurement result, and performing a second processing on the amplitude of the calibrated first sensing measurement result and the amplitude of the second sensing measurement result; correspondingly, the first device may calibrate the first sensing measurement result and the second sensing measurement result, and perform a second processing on the amplitude of the calibrated first sensing measurement result and the amplitude of the second sensing measurement result to obtain the fourth sensing measurement result.

[0036] For example, the second processing is one of the following: averaging, weighted averaging, maximum a posteriori probability processing, or maximum likelihood probability processing.

[0037] This design allows the fourth sensing measurement result to be obtained by incoherently combining the first and second sensing measurement results, thereby improving sensing performance. In some examples, when the first and second antenna ports occupy different frequency domain resources, incoherently combining the first and second sensing measurement results can improve the SNR. For example, when incoherently combining the ranging results corresponding to P antenna ports, the SNR can be improved by approximately √P to P times. In other examples, when the first and second antenna ports occupy different time domain resources, incoherently combining the first and second sensing measurement results can improve the SNR. For example, when incoherently combining the velocity measurement results corresponding to P antenna ports, the SNR can be improved by approximately √P to P times.

[0106] The technical solutions in the embodiments of this application will be described below with reference to the accompanying drawings. The technical solutions in the embodiments of this application can be applied to various communication systems, such as wireless local area networks (WLANs), wireless fidelity (Wi-Fi or WiFi) systems, fourth-generation (4G) mobile communication systems (such as long-term evolution (LTE) systems), fifth-generation (5G) mobile communication systems (such as new radio (NR) systems), or future communication systems. The methods provided in the embodiments of this application can be applied to terrestrial network communication systems or non-terrestrial network (NTN) communication systems. NTN communication systems can be, for example, satellite communication systems, and may also include unmanned aerial vehicles (UAVs), high-altitude platform stations (HAPS), and other aerial access network equipment; this application does not limit these aspects.

[0107] This application will present various aspects, embodiments, or features relating to systems that may include multiple devices, components, modules, etc. It should be understood and appreciated that individual systems may include additional devices, components, modules, etc., and / or may not include all the devices, components, modules, etc. discussed in conjunction with the accompanying drawings. Furthermore, combinations of these approaches are also possible.

[0108] Figure 1A A schematic diagram of a communication system provided in an embodiment of this application is shown as an example. Figure 1A As shown, the communication system includes a radio access network (RAN) 100 and a core network (CN) 200. Optionally, the communication system may also include an Internet 300.

[0109] RAN 100 includes at least one RAN node (such as...) Figure 1A 110a and 110b (collectively referred to as 110) and at least one terminal (such as Figure 1A RAN 100, denoted as RAN 120a-120j, is collectively referred to as RAN 120. RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment. Figure 1A(Not shown in the image). Terminal 120 is connected to RAN node 110 wirelessly. RAN node 110 is connected to core network 200 wirelessly or via wired connection. The core network equipment in core network 200 and RAN node 110 in RAN 100 can be different physical devices, or they can be the same physical device integrating core network logical functions and radio access network logical functions.

[0110] RAN 100 can be a cellular system related to the 3rd Generation Partnership Project (3GPP), such as 4G, 5G mobile communication systems, or future-oriented evolution systems. RAN 100 can also be an open RAN (ORAN or O-RAN), a cloud radio access network (CRAN), or a WiFi system. RAN 100 can also be a communication system that integrates two or more of the above systems.

[0111] RAN node 110, sometimes referred to as RAN entity or access node, constitutes part of the communication system and assists terminals in achieving wireless access. Multiple RAN nodes 110 in the communication system can be of the same type or different types. In some scenarios, the roles of RAN node 110 and terminal 120 are relative, for example... Figure 1A Network element 120i can be a helicopter or a drone, and it can be configured as a mobile base station. For terminals 120j that access RAN 100 through network element 120i, network element 120i is a base station; however, for base station 110a, network element 120i is a terminal. RAN node 110 and terminal 120 are sometimes referred to as communication devices, for example... Figure 1A Network elements 110a and 110b can be understood as communication devices with base station functions, while network elements 120a-120j can be understood as communication devices with terminal functions.

[0112] RAN nodes can also be described in different ways, such as access network equipment. Unless otherwise specified in this application, access network equipment will be used as the term.

[0113] Access network equipment can be devices or modules located on the network side of the aforementioned communication system and possessing corresponding communication functions. Access network equipment typically contains communication modules, circuits, or chips that perform the corresponding communication functions. Access network equipment may also be configured with programs or instructions for performing the corresponding communication functions, as well as the corresponding programs or instructions themselves.

[0114] In one possible scenario, access network equipment can be a base station (BS), an evolved NodeB (eNodeB or eNB), a transmission point (TP), an access point (AP), a transmit / receive point (TRP), a mobile switching center, a next-generation base station (NRNodeB, gNB), a next-generation base station in a future communication system, or an access node in a WiFi system, etc. Access network equipment can also be a macro base station (such as...). Figure 1A 110a), micro base stations or indoor stations (such as Figure 1A The access network equipment can be categorized as follows: 110b), relay nodes or donor nodes, wireless controllers in CRAN scenarios, satellites, drones, balloons, or aircraft, etc. Optionally, the access network equipment can also be servers, wearable devices, vehicles, or in-vehicle equipment, etc. For example, the access network equipment in vehicle-to-everything (V2X) technology can be a roadside unit (RSU). All or part of the functions of the access network equipment 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).

[0115] In another possible scenario, multiple access network devices collaborate to assist the terminal in achieving wireless access, with each device performing a portion of the base station's functions. For example, the access network devices can be a central unit (CU or control unit), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and DU can be separate entities or included in the same network element, such as a baseband unit (BBU). The RU can be included in radio frequency equipment or radio frequency units, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0116] 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-UP), and RU can also be called an open RU (O-RU). Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules.

[0117] For ease of description, the concepts of "access network equipment" and "site" will be used together in this application. Access network equipment can be understood as a collective term for all equipment (including sites) on the access network side; for example, one or more sites can be collectively referred to as access network equipment. A site can refer to a transmission node specifically located in a physical location. In other words, access network equipment conceptually includes sites.

[0118] A terminal is a device or module that connects to the aforementioned communication system and possesses corresponding communication functions. A terminal can also be called a terminal device, user equipment (UE), mobile station, mobile terminal, wireless terminal device, subscriber unit, subscriber station, mobile station, remote station, user terminal, user agent, or user device, etc. A terminal typically contains communication modules, circuits, or chips that perform the corresponding communication functions. The terminal can also be configured with programs or instructions for performing these communication functions.

[0119] Terminals can be widely used in various scenarios, such as device-to-device (D2D), V2X communication, machine-type communications (MTC), the Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, and smart cities. Terminals can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, vehicles, drones, helicopters, airplanes, ships, robots, robotic arms, smart home devices, etc. Wearable devices, also known as wearable smart devices or smart wearable devices, are a general term for devices that utilize wearable technology to intelligently design and develop everyday wearables. Terminals used in vehicles are called in-vehicle terminal devices, which include, for example, transportation vehicles with wireless communication capabilities, communication modules, or on-board units (OBUs).

[0120] For example, a terminal may include a mobile phone (or "cellular" phone), a computer with a mobile terminal device, or a portable, pocket-sized, handheld, or computer-embedded mobile device. For instance, a terminal may be a Personal Communication Service (PCS) phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), or other similar devices. A terminal may also include restricted devices, such as devices with limited power consumption, limited storage capacity, or limited computing power. For example, a terminal may be an information sensing device such as a barcode scanner, radio frequency identification (RFID), a sensor, a global positioning system (GPS), or a laser scanner. The embodiments of this application do not limit the device form of the terminal.

[0121] In this application, core network equipment refers to equipment in the core network that provides service support to terminals. For example, in the case where CN200 is the core network of a future communication system, a 5G core network, or an evolved 5G core network, some examples of core network equipment include: access and mobility management function (AMF) entities, session management function (SMF) entities, user plane function (UPF) entities, policy control function (PCF) entities, location management function (LMF) entities, etc., which are not listed here. Among them, the AMF entity can be responsible for the access management and mobility management of the terminal; the SMF entity can be responsible for session management, such as the establishment of user sessions; the UPF entity can be a user plane functional entity, mainly responsible for connecting to external networks; and the LMF entity can be responsible for the location management of the terminal. For example, in the case of CN200 as the 4G core network, some core network devices include: Mobility Management Entity (MME), Home Subscriber Server (HSS), Serving Gateway (S-GW), Policy and Charging Rules Function (PCRF), Public Data Network Gateway (PDN Gateway, P-GW), etc., which will not be listed here. It should be noted that in this application, entities can also be referred to as network elements or functional entities. For example, an AMF entity can also be called an AMF network element or AMF functional entity; similarly, an SMF entity can also be called an SMF network element or SMF functional entity; and similarly, an LMF entity can also be called an LMF network element or LMF functional entity. The above-mentioned core network devices can operate independently or be combined to implement certain control functions. For example, AMF, SMF, and PCF can be combined into a single core network device.

[0122] Figure 1B An exemplary schematic diagram of an ORAN system architecture provided in an embodiment of this application is shown. The ORAN system in this embodiment may include... Figure 1B Other components besides those shown. For example... Figure 1BAs shown, access network devices can communicate with the core network (CN) via a backhaul link and with terminals via an air interface. For example, a BBU in an access network device communicates with the core network via a backhaul link, and an RU in an access network device communicates with at least one terminal via an air interface. A BBU communicates with at least one RU via a fronthaul link; the BBU and RU may or may not be co-located. A BBU includes at least one CU and at least one DU, which can communicate via at least one midhaul link.

[0123] Figure 1C An exemplary diagram of the network element function division and protocol layer structure of an ORAN device provided in an embodiment of this application is shown.

[0124] In some possible implementations, the CU is a logical node that carries the radio resource control (RRC) layer, service data adaptation protocol (SDAP) layer, packet data convergence protocol (PDCP) layer, and other control functions of the access network equipment. The CU can connect to network nodes such as the core network through interfaces (e.g., E2 interfaces). Optionally, the CU can have some of the core network's functions. The CU (e.g., the PDCP layer and higher layers of the CU) connects to the DU (e.g., the radio link control (RLC) layer and lower layers of the DU) through interfaces (e.g., the F1 interface). Exemplarily, the F1 interface can provide control plane (C-Plane) and user plane (U-Plane) functions (e.g., interface management, system information management, UE context management, RRC message transmission, etc.). F1AP is the application protocol of the F1 interface, and in some examples, it defines the signaling procedures of F1. The F1 interface supports both the F1 control plane (F1-C) and the F1 user plane (F1-U).

[0125] In some examples, a CU may include CU-CP and CU-UP. CU-CP is a logical node carrying the control plane (PDCP-C) layer, which carries the RRC layer and the Packet Data Convergence Protocol layer, and is used to implement the CU's control plane functions. CU-CP can interact with network elements in the core network used to implement control plane functions. These network elements in the core network can be Access and Mobility Function (AMF) network elements, such as the AMF in a 5G system. CU-UP is a logical node carrying the user plane (PDCP-U) layer, which carries the SDAP layer and the Packet Data Convergence Protocol layer, and is used to implement the CU's user plane functions. CU-UP can interact with network elements in the core network used to implement user plane functions. These network elements in the core network are, for example, the UPF in a 5G system.

[0126] In some possible implementations, the DU is a logical node that carries the RLC layer, medium access control (MAC) layer, higher physical layer (Higher PHY) layer, and other functions. In some examples, the DU can control at least one RU. The DU connects to the RU through some interface (e.g., a fronthaul interface). In some examples, the Higher PHY layer includes the physical layer (PHY) processing, such as forward error correction (FEC) encoding and decoding, scrambling, modulation, and demodulation.

[0127] The above configurations of CU and DU are merely examples; the functions of CU and / or DU can be configured as needed. For instance, CU or DU can be configured to have more protocol layer functions, or to have 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 CU or DU can be divided according to service type or other system requirements, such as by latency, placing functions that need to meet low latency requirements in the DU and functions that do not need to meet such latency requirements in the CU.

[0128] In some possible implementations, the RU is a logical node that carries both the lower physical layer (Lower PHY) and radio frequency (RF) processing. In some examples, the RU may be a 3GPP TRP or RRH, or other similar functional entities. In some examples, the Low-PHY includes PHY processing functions such as Fast Fourier Transform (FFT), Inverse Fast Fourier Transform (IFFT), digital beamforming, and filtering. The RU communicates with one or more terminals via a wireless link.

[0129] The DU and RU can be co-located or not. The DU and RU exchange control plane and user plane information via a fronthaul link through a Lower-Layer Split CUS-Plane (LLS-CUS or LLS-C / U / S) interface. LLS-CUS may include a Lower-Layer Split C-Plane (LLS-C) interface providing the control plane (C-Plane) and a Lower-Layer Split U-Plane (LLS-U) interface providing the user plane (U-Plane). In some examples, the control plane refers to real-time control between the DU and RU. The DU and RU exchange management information via a Lower-Layer Split management (LLS-M) interface on the fronthaul link. The management plane (M-Plane) refers to non-real-time management operations between the DU and RU.

[0130] 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 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.

[0131] In some possible configurations, the communication system also includes a sensing management function. This sensing management function can be used to manage sensing. It can be a standalone network element, for example, a separate network element in the access network or core network; or it can be deployed or integrated into devices within the communication system, for example, in terminals, access network devices, or core network devices. The sensing management function may also have other names, such as sensing management network element, sensing management device, sensing management entity, sensing function (SF), integrated sensing and communication (ISAC) management function (ISACMF), ISAC service management function (ISACSMF), or sensing service management function (SSMF), etc., without limitation.

[0132] The following is combined with Figures 2 to 5 This section describes a communication system that includes perception management functions. Figures 2 to 5 For details on the specific equipment, please refer to the above text. Figures 1A to 1C Description of the equipment. For example. Figures 2 to 5 For details regarding the terminal, please refer to the above text. Figures 1A to 1C Explanation of the terminal. For example, Figures 2 to 5 For details regarding the access network equipment, please refer to the above text. Figures 1A to 1C Description of access network equipment. For example, Figures 2 to 5 For details regarding the core network equipment, please refer to the above text. Figures 1A to 1C Description of the core network equipment. Additionally... Figure 2 and Figure 4 The system illustrated uses AMF and UPF as examples. The names AMF and UPF may change as the communication system evolves. Functional network elements with similar functions to AMF can be understood as the AMF of this application. For example, AMF can also be called a mobility management network element or mobility management function, etc., without limitation. The name UPF may change as the communication system evolves. Functional network elements with similar functions to UPF can be understood as the UPF of this application. For example, UPF can also be called a user plane network element or user plane management network element, etc., without limitation.

[0133] Figure 2 A schematic diagram of another communication system provided in an embodiment of this application is illustrated. Figure 2As shown, the communication system may include: terminal 201, gNB 202, next generation evolved node B (ng-eNB) 203, AMF 204, UPF 205 and perception management function 206.

[0134] Terminal 201 can communicate with access network equipment (such as...) via the Uu interface. Figure 2 The access network devices communicate with each other via the gNB 202 and / or ng-eNB 203. Communication between access network devices is possible via the Xn interface. Communication between access network devices and AMF 204 is possible via the NG control plane (NG-C) interface. Communication between access network devices and UPF 205 is possible via the NG user plane (NG-U) interface. UPF 205 is connected to the user plane of Sensing Management Function 206, and AMF 204 is connected to the control plane of Sensing Management Function 206. Optionally, access network devices can communicate with the user plane of Sensing Management Function 206 via UPF 205 and with the control plane of Sensing Management Function 206 via AMF 204.

[0135] Optionally, in this communication system, the perception management function 206 may belong to the core network. For example, the perception management function 206 may be a core network device, or the perception management function 206 may be deployed or integrated into the core network device.

[0136] Optionally, the communication system also includes an LMF. An LMF is a network element, module, or component in the NR core network that provides location management for terminals. Optionally, the awareness management function 206 can be co-located with the location management function or deployed separately, without restriction.

[0137] It should be understood that Figure 2 The perception management function 206 shown is an example of an implementation where the user plane and control plane are separated to illustrate the technical solution of this application. The user plane and control plane of the perception management function 206 can also be integrated; there is no restriction on this.

[0138] It should also be understood that, Figure 2 In the communication system shown, AMF 204 and UPF 205 are optional. For example, when the communication system does not include AMF 204 and UPF 205, gNB 202 and ng-eNB 203 can be directly connected to the perception management function 206.

[0139] Figure 3 A schematic diagram of yet another communication system provided in an embodiment of this application is illustrated. For example... Figure 3As shown, the communication system may include: a terminal 301, an access network device 302, an access network device 303, and a sensing management function 304. The terminal 301 can communicate with the access network device (such as...) Figure 3 The access network device 302 and / or access network device 303 communicate with each other via the Xn interface. The sensing management function 304 can communicate with both access network device 302 and access network device 303.

[0140] In this communication system, the user plane and control plane of the perception management function 304 can be separate or not, without restriction.

[0141] Optionally, in this communication system, the perception management function 304 may belong to the core network or the access network. For example, the perception management function 304 may be a core network device, or the perception management function 304 may be deployed or integrated in the core network device. As another example, the perception management function 304 may be an access network device, or the perception management function 304 may be deployed or integrated in the access network device.

[0142] It should be understood that Figure 3 The system illustrated uses access network device 302 and access network device 303 connected to the same sensing management function as an example. Access network device 302 and access network device 303 can also be connected to different sensing management functions.

[0143] Figure 4 A schematic diagram of yet another communication system provided in an embodiment of this application is illustrated. For example... Figure 4 As shown, the communication system may include: terminal 401, access network device 402, access network device 403, UPF 404, and AMF 405. Terminal 401 can communicate with access network devices (such as...) Figure 4 The access network device 402 and / or access network device 403 communicate with each other via the Xn interface. The sensing management function can be deployed or integrated on the access network device 402. The access network device 402 can connect to the UPF 404 via the NG-U interface and to the AMF 405 via the NG-C interface. The access network device 403 can connect to the UPF 404 via the NG-U interface and to the AMF 405 via the NG-C interface.

[0144] Alternatively, if the access network device 402 adopts a separate architecture of CU and DU, the awareness management function can be deployed or integrated on the CU and / or DU.

[0145] The above Figures 2 to 4This is just one example of a communication system including two access network devices. The communication system may include at least one access network device, without limitation.

[0146] Figure 5 A schematic diagram of yet another communication system provided in an embodiment of this application is illustrated. For example... Figure 5 As shown, the communication system includes terminals, access network equipment, and core network equipment. Optionally, the communication system also includes operation administration and maintenance (OAM) equipment.

[0147] Different devices in this communication system can be connected via interfaces (e.g., NG or Xn interfaces) or air interfaces. For example, terminal access network devices can be connected via air interfaces. Alternatively, access network devices can be connected via Xn interfaces. Yet another example is that access network devices and core network devices can be connected via NG interfaces.

[0148] In a communication system, at least one of the following devices is equipped with one or more sensing modules (for clarity, Figure 5 (Only one sensing module is shown in the diagram): a terminal, access network device, core network device, or OAM. For example, the core network device may have one or more sensing modules. The terminal, access network device, and OAM may not have sensing modules. Another example: the access network device may have one or more sensing modules. The terminal, core network device, and OAM may not have sensing modules. Yet another example: the OAM may have one or more sensing modules. The terminal, access network device, and core network device may not have sensing modules. Yet another example: the terminal, access network device, core network device, and OAM may all have sensing modules. The sensing module can be used to implement or perform sensing functions; for example, the sensing module may be a sensing management function. The sensing modules deployed in different network elements may be the same or different.

[0149] The access network equipment can be a single access network node or include multiple access network nodes. For example, the access network equipment includes a CU and a DU. One or more sensing modules can be installed in each CU and / or DU. Optionally, the CU can also be divided into a CU-CP and a CU-UP. One or more sensing modules can be installed in each CU-CP and / or CU-UP.

[0150] Optionally, in the ORAN system, the sensing module can be a new module set in the access network equipment (e.g., one or more of CU, CU-CP, CU-UP, DU or RU), or the sensing module can be integrated with an existing module in the access network equipment (e.g., one or more of CU, CU-CP, CU-UP, DU or RU), that is, the existing functional module is functionally extended to enable it to realize the sensing function.

[0151] The communication systems and service scenarios described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new service scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0152] The relevant terms used in the embodiments of this application will be explained below. It should be noted that these explanations are for the purpose of making the embodiments of this application easier to understand, and should not be regarded as a limitation on the scope of protection claimed by this application.

[0153] I. ISAC:

[0154] Integrated communication and sensing technology is considered one of the key technologies for expanding the service capabilities of mobile communication networks. The core idea of ​​this technology is to add sensing capabilities to the mobile communication network, building capabilities such as target detection, tracking, and imaging, thereby integrating communication and sensing capabilities into a single network, achieving harmonious coexistence and mutual benefit. Please see [link to relevant documentation]. Figure 6 This is a schematic diagram of an integrated communication and sensing scenario. Figure 6 In the example, solid lines represent communication, and dashed lines represent sensing. Figure 6 As shown, access network devices can sense other objects by transmitting and receiving data on their own, or they can sense other objects while communicating with terminals. Figure 6 The example uses a smartphone as the terminal and drones, pedestrians, and vehicles as the sensing targets.

[0155] Sensing technologies can generally be categorized into three modes: mono-static sensing, bi-static sensing, and multi-static sensing.

[0156] In single-base sensing mode, the transmitting device for the sensing signal and the receiving device for the echo signal are the same device. In other words, in single-base sensing mode, the transmitting device both transmits the sensing signal and receives the echo signal obtained after the sensing signal has passed through the sensing target (e.g., reflection, diffraction, or scattering); or, in single-base sensing mode, the transmitter of the sensing signal and the receiver of the echo signal are located in the same device (or entity). Therefore, this single-base sensing mode can also be called a self-transmitting and self-receiving mode, without limitation.

[0157] Dual-base sensing mode refers to a mode where the transmitting device of the sensing signal and the receiving device of the echo signal are two different devices. In other words, sensing station A transmits a sensing signal, and the echo signal obtained after the sensing target is processed is received by sensing station B; or, the transmitter of the sensing signal and the receiver of the echo signal are located in different devices (or entities).

[0158] Multi-base sensing mode refers to a mode in which there are multiple transmitting devices for sensing signals and / or multiple receiving devices for the echo signals of the sensing signals. In other words, in multi-base sensing mode, there are multiple transmitting devices for transmitting sensing signals and / or multiple receiving devices for receiving the echo signals of the sensing signals; or, there are multiple transmitters for transmitting sensing signals and / or multiple receivers for receiving the echo signals of the sensing signals.

[0159] When there are multiple transmitting devices and one receiving device, the sensing scenario can be called a multi-transmitter, single-receiver scenario. For example, sensing station A and sensing node C each transmit sensing signals, and the echo signal obtained after the sensing signals pass through the sensing target is received by sensing station B. Another example is that sensing station A and sensing node B each transmit sensing signals, and the echo signal obtained after the sensing signals pass through the sensing target is received by sensing station B.

[0160] When there is one transmitting device and multiple receiving devices, this scenario can be called a one-to-many scenario. For example, sensing station A transmits a sensing signal, and the echo signal obtained after the sensing signal passes through a sensing target is received by sensing station B and sensing node C. Another example is that sensing station A transmits a sensing signal, and the echo signal obtained after the sensing signal passes through a sensing target is received by sensing station A and sensing node B.

[0161] When multiple transmitting devices and multiple receiving devices exist, the sensing scenario can be called a multiple-transmitter, multiple-receiver scenario. For example, sensing station A transmits a sensing signal, and the echo signal obtained after the sensing signal passes through a sensing target is received by sensing station B and sensing node D. Sensing station C transmits a sensing signal, and the echo signal obtained after the sensing signal passes through a sensing target is received by sensing station B and sensing node D. Another example: sensing station A transmits a sensing signal, and the echo signal obtained after the sensing signal passes through a sensing target is received by sensing station A and sensing node B. Sensing station C transmits a sensing signal, and the echo signal obtained after the sensing signal passes through a sensing target is received by sensing station B and sensing node D.

[0162] Figure 7 The diagram illustrates a sensing scenario to which the embodiments of this application are applicable. Figure 7 The document provides eight sensing scenarios applicable to the embodiments of this application, namely: the scenario where access network device A transmits and receives signals independently, i.e., the scenario where access network device A sends sensing signals and receives echo signals, such as... Figure 7 As shown in (1); the scenario where terminal A transmits and receives signals independently, that is, the scenario where terminal A sends sensing signals and receives echo signals, as shown in (1); Figure 7 As shown in (2) in the diagram; the scenario where access network device A sends a sensing signal and access network device B receives the echo signal, as follows: Figure 7 As shown in (3) in the diagram; the scenario where terminal A sends a sensing signal and terminal B receives the echo signal, as shown in the diagram. Figure 7 As shown in (4) in the diagram; the scenario where access network device A sends a sensing signal and terminal A receives the echo signal, as shown in the diagram. Figure 7 As shown in (5) in the example; the scenario where terminal A sends a sensing signal and access network device A receives the echo signal, as shown in the example. Figure 7 As shown in (6) in the diagram; under the control of access network device C, access network device A sends sensing signals and access network device B receives echo signals, as in the following scenario. Figure 7 As shown in (7) in the diagram; under the control of access network device A, the scenario in which terminal A sends a sensing signal and terminal B receives an echo signal is as follows: Figure 7 As shown in (8) of the text. Figure 7 The example shown uses a vehicle as the sensing target and a smartphone as the terminal.

[0163] As shown above, in the sensing scenario to which this application embodiment applies, there may be one or more transmitting devices for transmitting sensing signals, and one or more receiving devices for receiving echo signals of the sensing signals. Figure 7 This explanation uses one transmitting device and one receiving device as an example, without limitation.

[0164] The sensing target can also be referred to as a target, a detected target, a sensed object, a sensed device, etc., without limitation. The sensing target can be any tangible object in the environment capable of interacting with electromagnetic waves (e.g., reflection, diffraction, or scattering). For example, the sensing target can be a stationary object such as a mountain, forest, or building. Alternatively, the sensing target can be a mobile object such as a vehicle, drone, pedestrian, or terminal. The embodiments of this application do not limit the specific implementation form of the sensing target.

[0165] The sensing measurement result can also be referred to as the sensing result, the detected result, the detected data, or the detected data, etc., without limitation. The sensing measurement result can be the result obtained by the receiving device processing the echo signal. For example, the sensing measurement result may include at least one of the following: the position of the sensing target, the velocity of the sensing target, the distance from the sensing target to the receiving device, the distance from the sensing target to the transmitting device, the direction of the sensing target, the angle of the sensing target, the intensity of the echo signal from the sensing target, etc.

[0166] II. Sensing Signals:

[0167] In this application, the sensing signal may include a reference signal and / or a communication signal other than a reference signal.

[0168] The reference signal, also known as the pilot signal, is essential in communication systems for transmitting and receiving data, obtaining system synchronization and feedback channel information, and estimating the uplink or downlink channel. Channel estimation refers to the process of reconstructing or recovering the received signal to compensate for signal distortion caused by channel fading and noise fading. It uses known reference signals from both the transmitter and receiver to determine the time and frequency domain variations of the channel. These reference signals, also called reference signals, are distributed across one or more resource elements (REs) in the time-frequency two-dimensional space within orthogonal frequency division multiplexing (OFDM) symbols, and have known amplitude and phase.

[0169] In some implementations, the reference signal may be a reference signal used for communication. For example, the reference signal used for communication may include, but is not limited to, at least one of the following: a sounding reference signal (SRS), an uplink demodulation reference signal (DMRS), an uplink phase tracking reference signal (PTRS), an uplink positioning RS, a positioning reference signal (PRS), a downlink DMRS, PTRS, a channel state information reference signal (CSI-RS), a tracking reference signal (TRS), or a cell reference signal (CRS), etc.

[0170] Optionally, the reference signal used for communication can be used for sensing.

[0171] In other implementations, the reference signal may be a reference signal specifically for sensing.

[0172] It should be understood that the reference signals listed above are merely examples and should not be construed as limiting this application. This application does not preclude the possibility of defining other reference signals in future agreements to achieve the same or similar functions.

[0173] III. Beam:

[0174] Mobile communication systems (such as 5G mobile communication systems) can employ high-frequency communication, meaning they use high-frequency signals to transmit data. A major problem with high-frequency communication is that signal energy decreases sharply with transmission distance, resulting in short transmission ranges. To overcome this problem, high-frequency communication uses analog beamforming technology. By weighting the antenna array, the signal energy is concentrated within a small angular range, forming a beam-like signal (called an analog beam, or simply a beam), thereby increasing the transmission distance. Access network equipment and terminals can both use beamforming for transmission.

[0175] In protocols (e.g., NR protocol), beams can be referred to as spatial domain filters, spatial filters, spatial domain parameters, spatial parameters, spatial domain settings, or spatial settings. Beams can also be represented by transmission configuration indicator state parameters or spatial relation parameters. The English term for transmission configuration indicator state can be transmission configuration indicator state (TCI-state), transmission configuration indication state (TCI-state), or transmission configuration index state (TCI-state), etc. Therefore, in this application, beams can be replaced by spatial domain filters, spatial filters, spatial parameters, spatial parameters, spatial settings, spatial settings, TCI-state (e.g., downlink TCI-state, DL TCI-state, and / or uplink TCI-state, UL TCI-state), or spatial relations, etc. The terms mentioned above are also equivalent to each other. Beam may also be replaced with other beam terms, which are not limited in this application.

[0176] The beam used to transmit signals can be called a transmission beam (Tx beam), a spatial domain transmission filter, a spatial transmission filter, a spatial domain transmission parameter, a spatial transmission parameter, a spatial domain transmission setting, or a spatial transmission setting.

[0177] The beam used to receive signals can be called a reception beam (Rx beam), a spatial domain reception filter, a spatial reception filter, a spatial domain reception parameter, a spatial reception parameter, a spatial domain reception setting, or a spatial reception setting.

[0178] The transmitting beam can refer to the distribution of signal strength in different directions in space after a signal is transmitted through an antenna, while the receiving beam can refer to the distribution of signal strength in different directions in space of a wireless signal received from an antenna.

[0179] Furthermore, the beam can be a wide beam, a narrow beam, or other types of beam. The beamforming technology can be beamforming technology or other technologies. Beamforming technology can be, for example, digital beamforming technology, analog beamforming technology, or hybrid beamforming technology. In this application, the beam can be an analog beam or a digital beam.

[0180] In some implementations, access network devices can indicate the physical downlink shared channel (PDSCH) beam information of the terminal through the transmission configuration indicator (TCI) field in the downlink control information (DCI). The English terms for transmission configuration indicator (TCI), transmission configuration indication (TCI), or transmission configuration index (TCI) may include these.

[0181] IV. Antenna Port:

[0182] An antenna port, often simply called a port, is a logical concept. It can be understood as a virtual transmitting antenna (or antenna array) identified by the receiver, or a spatially distinguishable virtual transmitting antenna (or antenna array). An antenna port generally corresponds to a physical antenna. Each antenna port represents a channel model, which can be derived from a reference signal on the antenna port. Therefore, an antenna port is usually associated with a reference signal, and its meaning can be understood as a transmit / receive interface on the channel through which the reference signal passes. Because antenna ports can be associated with reference signals, each antenna port can be called a port for a reference signal, such as a CSI-RS port, DMRS port, or SRS port. For low frequencies, an antenna port may correspond to one or more antenna elements that jointly transmit the reference signal; the receiver can treat them as a whole without distinguishing between individual elements. For high-frequency systems, an antenna port may correspond to a beam; similarly, the receiver only needs to treat this beam as an interface without distinguishing between individual elements.

[0183] In protocols, antenna ports are typically identified by "antenna port" or "port," but they can also be identified by resources (such as CSI-RS resources, SRS resources, DMRS resources, PTRS resources, CRS resources, or TRS resources) or resource groups. In other words, the identifier for an antenna port can be replaced with one of the above-mentioned identifiers; for example, an antenna port can be replaced with an identifier for a resource, a pilot resource, or a reference signal resource.

[0184] In communication systems, multi-port typically refers to the ability of a single device (e.g., an access network device or terminal) to be configured with multiple antenna ports, thereby supporting technologies such as spatial multiplexing, beamforming, and diversity. Each antenna port can be considered an independent radio frequency signal channel, and different antenna ports can be used to transmit and receive different signals, thus improving the overall performance of the system.

[0185] V. Quasi-colocation (QCL):

[0186] In 3GPP wireless communication standards (such as LTE or 5G NR standards), quasi-colocation relationships can be used to describe the relationship between multiple antenna ports sharing certain wireless channel characteristics. Quasi-colocation relationships define the correlation of different ports in the physical layer channel propagation characteristics, enabling the receiver to use this information for efficient signal processing and demodulation.

[0187] In simple terms, if two antenna ports are quasi-co-located, the channel characteristics of one antenna port (e.g., one or more of Doppler shift, delay spread, and angular spread) can be derived from the other antenna port. In other words, when two antenna ports are quasi-co-located, the channel estimation result obtained from one antenna port can be applied to the other port; or, the signals on these two antenna ports can reuse parameters. This reduces the overhead of channel estimation and improves system efficiency.

[0188] For example, the current standard defines four types of quasi-co-location relationships, that is, four types of QCLs. These four quasi-co-location relationships are shown in Table 1.

[0189] Table 1

[0190]

[0191] All four types of quasi-colocation relationships mentioned above are used for communication.

[0192] VI. In this application, "instruction" or "for instruction" may include explicit instruction (or direct instruction) and implicit instruction (or indirect instruction). When describing information for instructing A, it may include whether the information explicitly instructs A or implicitly instructs A, but does not necessarily mean that the information carries A.

[0193] The indication methods involved in the embodiments of this application should be understood to cover various methods that enable the party to be indicated to obtain the information to be indicated. The information to be indicated can be sent as a whole or divided into multiple sub-information and sent separately. Moreover, the sending period and / or sending time of these sub-information can be the same or different, without limitation.

[0194] In the embodiments of this application, "information" can be an explicit indication, that is, a direct indication through signaling, or obtained by combining other rules or parameters with parameters indicated by signaling, or by deduction. It can also be an implicit indication, that is, obtained based on rules or relationships, or based on other parameters, or by deduction. No limitation is imposed.

[0195] VII. In this application, communication between different devices can refer to direct communication between different devices (i.e., without the need for relaying or forwarding by other devices), or communication between different devices through other devices (i.e., requiring relaying or forwarding by other devices), or communication between a functional unit within a device and other devices through another functional unit. For example, "sending information to…(terminal)" can be understood as the destination of the information being the terminal, and may include sending information directly or indirectly to the terminal. "Receiving information from…(terminal)" can be understood as the source of the information being the terminal, and may include receiving information directly or indirectly from the terminal. Information may undergo necessary processing between the source and destination ends, such as format changes, digital-to-analog conversion, amplification, filtering, etc., but the destination end can understand the valid information from the source end. Similar expressions in this application can be understood in a similar way, and will not be elaborated further here.

[0196] 8. In this application, the words "exemplarily," "for example," "for instance," and "example" are used to indicate examples, illustrations, or explanations, and are not intended to limit the scope of protection of this application. It should be understood that the examples in this application may also be implemented in other ways. In this application, "of," "corresponding (relevant)," and "corresponding" may sometimes be used interchangeably, and it should be noted that when their distinction is not emphasized, their intended meanings are consistent.

[0197] 9. In this application, any two of the programs, instructions, and code may be substituted for one another.

[0198] 10. In this application, "greater than or equal to" and "greater than" can be used interchangeably. For example, "A is greater than threshold 1" and "A is greater than or equal to threshold 1" can be used interchangeably. "Less than or equal to" and "less than" can be used interchangeably. For example, "A is less than threshold 1" and "A is less than or equal to threshold 1" can be used interchangeably.

[0199] XI. In this application, “in the case of…”, “when…”, “if…”, and “if…” can have the same meaning and can be used interchangeably.

[0200] 12. In this application, the sensing measurement result corresponding to a certain antenna port can be replaced by at least one of the following: the sensing measurement result corresponding to the reference signal transmitted by the antenna port.

[0201] In this application, the sensing measurement result corresponding to a certain reference signal can be replaced by at least one of the following: the sensing measurement result obtained based on the reference signal; the sensing measurement result obtained based on the echo signal of the reference signal; the sensing measurement result obtained by measuring the reference signal; or the sensing measurement result obtained by measuring the echo signal of the reference signal.

[0202] Thirteen, in this application, reporting, feedback, and sending are interchangeable.

[0203] XIV. In this application, the linear fitting curve may be referred to as the fitted straight line.

[0204] 15. In this application, when illustrating configuration information, the configuration information may include N lines of information, where N is a positive integer. The n1th line of information in the N lines of information may belong to the n2th line of information in the N lines of information; in other words, the n2th line of information may include the n1th line of information. n1 is an integer from 2 to N, and n2 is a positive integer less than n1. The indentation value #1 of the n2th line of information is less than the indentation value #2 of the n1th line of information; among the information preceding the n1th line of information with an indentation value of indentation value #1, the n2th line of information is the line of information closest to the n1th line of information.

[0205] For example, the configuration information may be CSI-RS resource configuration information (CSI-RS-ResourceConfig), which may include:

[0206]

[0207] Among them, bwp-ID, resourceType, and CSI-RS-ResourceSet can belong to CSI-RS-ResourceConfig; Resource 1 can belong to CSI-RS-ResourceSet.

[0208] XVI. In this application, h p (r) can be the range profile corresponding to the p-th antenna port, where r is the distance and p is the index of the p-th antenna port. p (v) can be the velocity profile corresponding to the p-th antenna port, where v is the velocity and p is the index of the p-th antenna port.

[0209] As mentioned earlier, current quasi-co-location relationships are defined from the perspectives of channel delay spread, Doppler spread, average delay, Doppler shift, and spatial reception parameters. These parameters define the correlation of different antenna ports in terms of physical layer channel propagation characteristics. However, these quasi-co-location relationships are not applicable to sensing. This is because sensing involves measuring the parameters of targets in the environment, not measuring the channel. When the channel characteristics of two antenna ports are similar, the sensing targets corresponding to these two antenna ports may be completely different; and / or, when the channel differences between two antenna ports are significant, the sensing targets corresponding to these two antenna ports may be the same.

[0210] Therefore, how to perform sensing, for example, based on the quasi-co-location relationship between two antenna ports, requires further research.

[0211] The execution subject involved in the embodiments of this application will be introduced below.

[0212] The first device can be a terminal, or a device applicable to a terminal (e.g., a module, communication module, circuit, chip (such as a modem chip, or a SoC chip or SIP chip containing a modem core), chip system, or processor), or a logical node, logical module, or software capable of implementing all or part of the terminal's functions.

For example, the second device may implement the functions of the sensing management function; or, the second device and the sensing management function may be the same device. Alternatively, the second device and the sensing management function may be devices implementing different functions within the same device. In this implementation, the step of transmitting information (or messages) between the second device and the sensing management function is optional.

The sensing management function can be... Figure 3 The sensing management function 304 in the middle. For example, the second device can be... Figure 7 The access network device A in (5) is or a device in the access network device A; the perception management function can be a perception management function independent of the access network device A.

[0218] Optionally, the method performed by the perception management function in this application may also be performed by a device for the perception management function (e.g., a module, a communication module, a circuit or chip responsible for communication and / or perception functions (such as a modem chip, or a SoC chip or SIP chip containing a modem core), a chip system, or a processor), or may be implemented by a logic node, logic module, or software capable of implementing all or part of the functions of the first device, or may be implemented by a combination of hardware and software.

[0219] It is understood that in the embodiments of this application, at least one of the first device, the second device, or the sensing management function may perform some or all of the steps in the embodiments of this application. These steps or operations are merely examples, and the embodiments of this application may also perform other operations or variations thereof. Furthermore, the steps may be performed in different orders as presented in the embodiments of this application, and it is not necessarily necessary to perform all the operations in the embodiments of this application.

[0220] This application provides a communication method. Optionally, in this method, the second device and the sensing management function may reside in the same device (e.g., an access network device). Figure 8 This is a flowchart illustrating the communication method provided in an embodiment of this application. Figure 8 As shown, the method includes:

[0221] S801: The first device sends capability information; correspondingly, the second device receives capability information.

[0222] This capability information can be used to indicate the capabilities of the first device. The first device is a means applied to the first device. Optionally, the first device may be located within the first device, or it may be physically independent of the first device. For example, the first device is a terminal.

[0223] Optionally, this capability information can be used to indicate at least one of the following: the first device supports coherent combining of sensing measurement results corresponding to multiple antenna ports; the first device supports incoherent combining of sensing measurement results corresponding to multiple antenna ports; the first device supports feeding back sensing measurement results corresponding to different antenna ports among the multiple antenna ports respectively; the first device supports feeding back a first processing result, which is obtained by coherently combining the sensing measurement results corresponding to multiple antenna ports; the first device supports feeding back a second processing result, which is obtained by incoherent combining of sensing measurement results corresponding to multiple antenna ports; the first device does not support coherent combining of sensing measurement results corresponding to multiple antenna ports; the first device does not support incoherent combining of sensing measurement results corresponding to multiple antenna ports; the first device does not support feeding back sensing measurement results corresponding to different antenna ports among the multiple antenna ports respectively; the first device does not support feeding back the first processing result; or, the first device does not support feeding back the second processing result. These are described below.

[0224] 1. Capability information is used to indicate that the first device supports coherent merging of sensing measurement results corresponding to multiple antenna ports.

[0225] Optionally, the capability information used to indicate that the first device supports coherent combining processing of sensing measurement results corresponding to multiple antenna ports can be replaced by at least one of the following: the capability information used to indicate that the first device has multi-antenna port coherent combining processing capability; the capability information used to indicate that the first device is able to perform coherent combining processing of sensing measurement results corresponding to multiple antenna ports; the capability information used to indicate that the first device supports coherent combining processing of sensing measurement results corresponding to multiple reference signals; or, the capability information used to indicate that the first device is able to perform coherent combining processing of sensing measurement results corresponding to multiple reference signals.

[0226] In some examples, capability information may include bit #1. When bit #1 is value #1 (e.g., 1 or 0), this capability information indicates that the first device supports coherent combining of sensing measurement results corresponding to multiple antenna ports. Conversely, when bit #1 is value #2 (e.g., 0 or 1), this capability information indicates that the first device does not support coherent combining of sensing measurement results corresponding to multiple antenna ports. Optionally, value #1 and value #2 are different. For example, value #1 is 0 and value #2 is 1. Or, for example, value #1 is 1 and value #2 is 0.

[0227] In other examples, field #1 is used to indicate that the first device supports coherent combining of sensing measurement results corresponding to multiple antenna ports. When the capability information includes field #1, this capability information is used to indicate that the first device supports coherent combining of sensing measurement results corresponding to multiple antenna ports.

[0228] In some other examples, field #2 is used to indicate that the first device does not support coherent combining of sensing measurement results corresponding to multiple antenna ports. When the capability information does not include field #2, this capability information is used to indicate that the first device supports coherent combining of sensing measurement results corresponding to multiple antenna ports.

[0229] 2. Capability information is used to indicate that the first device supports noncoherent merging of sensing measurement results corresponding to multiple antenna ports.

[0230] Optionally, the capability information used to indicate that the first device supports noncoherent combining of sensing measurement results corresponding to multiple antenna ports can be replaced by at least one of the following: the capability information used to indicate that the first device has multi-antenna port noncoherent combining capability; the capability information used to indicate that the first device can perform noncoherent combining of sensing measurement results corresponding to multiple antenna ports; the capability information used to indicate that the first device supports noncoherent combining of sensing measurement results corresponding to multiple reference signals; or, the capability information used to indicate that the first device can perform noncoherent combining of sensing measurement results corresponding to multiple reference signals.

[0231] In some examples, the capability information may include bit #2. When bit #2 is value #3 (e.g., 1 or 0), this capability information indicates that the first device supports incoherent combining of sensing measurement results corresponding to multiple antenna ports. Conversely, when bit #2 is value #4 (e.g., 0 or 1), this capability information indicates that the first device does not support incoherent combining of sensing measurement results corresponding to multiple antenna ports. Optionally, value #3 and value #4 are different. For example, value #3 is 0 and value #4 is 1. Or, for example, value #3 is 1 and value #4 is 0.

[0232] In other examples, field #3 is used to indicate that the first device supports incoherent merging of sensing measurement results corresponding to multiple antenna ports. When the capability information includes field #3, this capability information is used to indicate that the first device supports incoherent merging of sensing measurement results corresponding to multiple antenna ports.

[0233] In some other examples, field #4 is used to indicate that the first device does not support incoherent merging of sensing measurement results corresponding to multiple antenna ports.

[0276] In some possible ways, the capability information is also used to indicate at least one of the following: the first device supports sensing based on a reference signal, or the first device does not support sensing based on a reference signal. These will be explained separately below.

[0277] (1) Capability information is used to indicate that the first device supports sensing based on reference signals.

[0278] Optionally, the capability information used to indicate that the first device supports sensing based on a reference signal can be replaced with: the capability information used to indicate that the first device is capable of sensing based on a reference signal.

[0279] For example, capability information is used to indicate that the first device supports sensing based on reference signals used for communication. For instance, capability information is used to indicate that the first device supports sensing based on CSI-RS.

[0280] In some examples, capability information may include bit #6. When bit #6 is value #11 (e.g., 1 or 0), this capability information indicates that the first device supports sensing based on a reference signal. Conversely, when bit #6 is value #12 (e.g., 0 or 1), this capability information indicates that the first device does not support sensing based on a reference signal. Optionally, value #11 and value #12 may be different. For example, value #11 may be 0 and value #12 may be 1. Or, for example, value #11 may be 1 and value #12 may be 0.

[0281] In other examples, field #11 is used to indicate that the first device supports sensing based on a reference signal. When the capability information includes field #11, the capability information is used to indicate that the first device supports sensing based on a reference signal.

[0282] In some other examples, field #12 is used to indicate that the first device does not support sensing based on a reference signal. Where the capability information does not include field #12, this capability information is used to indicate that the first device supports sensing based on a reference signal.

[0283] (2) Capability information is used to indicate that the first device does not support sensing based on reference signals.

[0284] Optionally, the capability information used to indicate that the first device does not support sensing based on the reference signal can be replaced with: the capability information used to indicate that the first device is unable to sense based on the reference signal.

[0285] For example, capability information is used to indicate that the first device does not support sensing based on reference signals used for communication. For instance, capability information is used to indicate that the first device does not support sensing based on CSI-RS.

[0286] In some examples, capability information may include bit #6. The specific content of bit #6 can be found in the description of bit #6 above, and will not be repeated here. When bit #6 takes the value #12 (e.g., 0 or 1), this capability information is used to indicate that the first device does not support sensing based on the reference signal.

[0287] In other examples, field #11 is used to indicate that the first device supports sensing based on a reference signal. Where the capability information does not include field #11, this capability information is used to indicate that the first device does not support sensing based on a reference signal.

[0288] In other examples, field #12 is used to indicate that the first device does not support sensing based on a reference signal. When the capability information includes field #12, this capability information is used to indicate that the first device does not support sensing based on a reference signal.

[0289] Capability information can be carried in traditional messages or in new messages, without restriction. For example, capability information can be carried in RRC messages, medium access control-control element (MAC CE) messages, or uplink control information (UCI).

[0290] Capability information may also have other names, such as capability reporting information, without restriction.

[0291] Through S801, the first device can report capability information, so that the second device can manage the first device according to the capability information. For example, it can determine the configuration information in S802 according to the capability information, thereby determining the configuration information that matches the capability of the first device, thereby improving the accuracy of the configuration.

[0292] S801 is an optional step. For example, by default, the first device supports coherent combining of sensing measurement results corresponding to multiple antenna ports. If the first device supports coherent combining of sensing measurement results corresponding to multiple antenna ports, the first device may not send capability information. Alternatively, by default, the first device supports incoherent combining of sensing measurement results corresponding to multiple antenna ports. If the first device supports incoherent combining of sensing measurement results corresponding to multiple antenna ports, the first device may not send capability information. Yet another example, by default, the first device supports separately feeding back sensing measurement results corresponding to different antenna ports among multiple antenna ports. If the first device supports separately feeding back sensing measurement results corresponding to different antenna ports among multiple antenna ports, the first device may not send capability information. Yet another example, by default, the first device supports feeding back a first processing result. If the first device supports feeding back a first processing result, the first device may not send capability information. Yet another example, by default, the first device supports feeding back a second processing result. If the first device supports feeding back a second processing result, the first device may not send capability information. Finally, by default, the first device does not support coherent combining of sensing measurement results corresponding to multiple antenna ports. If the first device does not support coherent combining of sensing measurement results corresponding to multiple antenna ports, the first device may not transmit capability information. For example, by default, the first device does not support incoherent combining of sensing measurement results corresponding to multiple antenna ports. If the first device does not support incoherent combining of sensing measurement results corresponding to multiple antenna ports, the first device may not transmit capability information. For example, by default, the first device does not support separately feeding back sensing measurement results corresponding to different antenna ports among multiple antenna ports. If the first device does not support separately feeding back sensing measurement results corresponding to different antenna ports among multiple antenna ports, the first device may not transmit capability information. For example, by default, the first device does not support feeding back the first processing result. If the first device does not support feeding back the first processing result, the first device may not transmit capability information. For example, by default, the first device does not support feeding back the second processing result. If the first device does not support feeding back the second processing result, the first device may not transmit capability information.

[0293] S802: The second device sends configuration information; correspondingly, the first device receives the configuration information.

[0294] The configuration information can be used to configure (or indicate) a first quasi-co-location relationship. The first quasi-co-location relationship can be a quasi-co-location relationship for sensing between a first antenna port and a second antenna port.

[0295] Optionally, the quasi-co-location relationship for sensing between the first antenna port and the second antenna port can be replaced by: the quasi-co-location relationship for sensing between the first reference signal and the second reference signal. For example, when different antenna ports are associated with (or correspond to) different reference signals, the quasi-co-location relationship between the antenna ports can be replaced by the quasi-co-location relationship between the reference signals. Correspondingly, the quasi-co-location relationship for sensing between the first antenna port and the second antenna port can be replaced by: the quasi-co-location relationship for sensing between the first reference signal and the second reference signal. Wherein, the first reference signal may be a signal transmitted through the first antenna port; for example, the first reference signal may be a signal transmitted by the second device through the first antenna port. The second reference signal may be a signal transmitted through the second antenna port; for example, the second reference signal may be a signal transmitted by the second device through the second antenna port.

[0296] In some implementations, the first quasi-co-location relationship is either a first-type quasi-co-location relationship or a second-type quasi-co-location relationship. These will be explained separately below.

[0297] 1. Type I quasi-co-address relationship:

[0298] The first type of quasi-co-location relationship may include: the beam corresponding to the first antenna port and the beam corresponding to the second antenna port do not overlap spatially; in other words, when the first quasi-co-location relationship is the first type of quasi-co-location relationship, the beam corresponding to the first antenna port and the beam corresponding to the second antenna port do not overlap spatially. Thus, when the first quasi-co-location relationship is the first type of quasi-co-location relationship, the reference signal transmitted by the first antenna port and the reference signal transmitted by the second antenna port can be used to sense different targets respectively.

[0299] Optionally, the non-overlapping spatial beams of the first and second antenna ports can be replaced by at least one of the following: the spatial filter corresponding to the first and second antenna ports are different (or independent); the parameters of the spatial filter corresponding to the first and second antenna ports are different; the parameters of the spatial filter corresponding to the first and second antenna ports are set separately (or independently); the beams corresponding to the first and second antenna ports are independent; the beam used to carry (or transmit) the first reference signal and the beam used to carry (or transmit) the second reference signal do not overlap spatially; the beams corresponding to the first and second reference signals do not overlap spatially; the beams corresponding to the first and second reference signals are independent; the spatial filter corresponding to the first and second reference signals are different (or independent); the parameters of the spatial filter corresponding to the first and second reference signals are different; or, the parameters of the spatial filter corresponding to the first and second reference signals are set separately (or independently).

[0300] For example, such as Figure 9A As shown, the beam corresponding to the first antenna port is the beam corresponding to P1, and the beam corresponding to the second antenna port is the beam corresponding to P2. The beams corresponding to P1 and P2 do not overlap in space.

[0301] Optionally, the non-overlapping of the beams corresponding to the first antenna port and the second antenna port in space can include: the non-overlapping of the beams corresponding to the first antenna port and the second antenna port within a beamwidth range corresponding to x dB. In other words, when the beams corresponding to the two antenna ports do not overlap within a beamwidth range corresponding to x dB, the beams corresponding to these two antenna ports can be understood as spatially non-overlapping, and the quasi-co-location relationship used for sensing between these two antenna ports can be a first-type quasi-co-location relationship. Here, x can be a positive number, for example, x is 3.

[0302] For example, such as Figure 9B As shown, the beam corresponding to the first antenna port is the beam corresponding to P1, and the beam corresponding to the second antenna port is the beam corresponding to P2. The beams corresponding to P1 and P2 do not overlap spatially. In this case, the first quasi-co-location relationship between the first antenna port and the second antenna port can be a first type of quasi-co-location relationship.

[0303] For example, such as Figure 9CAs shown, the beam corresponding to the first antenna port is the beam corresponding to P1, and the beam corresponding to the second antenna port is the beam corresponding to P2. The beams corresponding to P1 and P2 overlap spatially, but they do not overlap within the beamwidth range corresponding to 3 dB. In this case, the first quasi-co-location relationship between the first antenna port and the second antenna port can be a first type of quasi-co-location relationship.

[0304] The first type of quasi-colocation relationship may also have other names, such as perception type A quasi-colocation relationship, type E quasi-colocation relationship, or perception type E quasi-colocation relationship, etc., without restriction.

[0305] Optionally, when the first quasi-co-location relationship is a first type of quasi-co-location relationship, the configuration information is also used to configure at least one of the following: the beam direction corresponding to the first antenna port, the beam direction corresponding to the second antenna port, the beamwidth corresponding to the first antenna port, or the beamwidth corresponding to the second antenna port. The beam direction can be replaced with the main beam direction.

[0306] 2. Second type of quasi-co-address relationship:

[0307] The second type of quasi-co-location relationship includes: the beam corresponding to the first antenna port and the beam corresponding to the second antenna port spatially overlap; in other words, when the first quasi-co-location relationship is the second type of quasi-co-location relationship, the beam corresponding to the first antenna port and the beam corresponding to the second antenna port spatially overlap. Thus, when the first quasi-co-location relationship is the second type of quasi-co-location relationship, the reference signal transmitted by the first antenna port and the reference signal transmitted by the second antenna port can be used to sense the same target respectively.

[0308] Optionally, the beams corresponding to the first antenna port and the second antenna port may overlap spatially, which may include: the beams corresponding to the first antenna port and the second antenna port partially or completely overlapping spatially.

[0309] Optionally, the spatial overlap of the beams corresponding to the first antenna port and the second antenna port can be replaced by at least one of the following: the spatial filter corresponding to the first antenna port and the spatial filter corresponding to the second antenna port are the same; the parameters of the spatial filter corresponding to the first antenna port and the parameters of the spatial filter corresponding to the second antenna port are the same; the beam used to carry (or transmit) the first reference signal and the beam used to carry (or transmit) the second reference signal are spatially overlapped; the beam corresponding to the first reference signal and the beam corresponding to the second reference signal are spatially overlapped; the spatial filter corresponding to the first reference signal and the spatial filter corresponding to the second reference signal are the same; or, the parameters of the spatial filter corresponding to the first reference signal and the parameters of the spatial filter corresponding to the second reference signal are the same.

[0310] For example, such as Figure 9D As shown, the beam corresponding to the first antenna port is the beam corresponding to P1, and the beam corresponding to the second antenna port is the beam corresponding to P2. The beams corresponding to P1 and P2 overlap in space.

[0311] In some implementations, the first antenna port and the second antenna port can be distinguished by their polarization direction; in other words, the first antenna port and the second antenna port correspond to different polarization directions. For example, ... Figure 9D As shown, the polarization directions corresponding to the first antenna port and the second antenna port are different. The first antenna port corresponds to the first polarization direction, and the second antenna port corresponds to the second polarization direction.

[0312] In other implementations, the first antenna port and the second antenna port can be distinguished by antenna array elements. For example, such as Figure 9E As shown, the first antenna port corresponds to the first group of antenna elements. The second antenna port corresponds to the second group of antenna elements.

[0313] Optionally, the spatial overlap of the beams corresponding to the first antenna port and the second antenna port can include: the overlap of the beams corresponding to the first antenna port and the second antenna port within a beamwidth range corresponding to x dB. That is, when the beams corresponding to the two antenna ports overlap within a beamwidth range corresponding to x dB, the beams corresponding to these two antenna ports can be understood as spatially overlapping, and the quasi-co-location relationship used for sensing between these two antenna ports can be a second type of quasi-co-location relationship. Here, x can be a positive number, for example, x is 3.

[0314] Optionally, the beams corresponding to the first antenna port and the second antenna port overlap within the beamwidth range corresponding to x dB. This can be understood as: there is an overlap between the beams corresponding to the first antenna port and the second antenna port within the beamwidth range corresponding to x dB.

[0315] For example, such as Figure 9F As shown, the beam corresponding to the first antenna port is the beam corresponding to P1, and the beam corresponding to the second antenna port is the beam corresponding to P2. The beams corresponding to P1 and P2 overlap within the beamwidth range corresponding to 3 dB. In this case, the first quasi-co-location relationship between the first antenna port and the second antenna port can be a second type of quasi-co-location relationship.

[0316] The second type of quasi-colocation relationship may also have other names, such as perception type B quasi-colocation relationship, type F quasi-colocation relationship, or perception type F quasi-colocation relationship, etc., without restriction.

[0317] Optionally, when the first quasi-co-location relationship is a first type of quasi-co-location relationship, the configuration information is further used to configure at least one of the following: the beam direction corresponding to the first antenna port, the beam direction corresponding to the second antenna port, and the overlap portion of the beam corresponding to the first antenna port and the beam corresponding to the second antenna port. Optionally, the configuration information used to configure the overlap portion of the beam corresponding to the first antenna port and the beam corresponding to the second antenna port may include at least one of the following: the configuration information is used to configure the width of the overlap portion of the beam corresponding to the first antenna port and the beam corresponding to the second antenna port, or the configuration information is used to configure the coverage area of ​​the overlap portion of the beam corresponding to the first antenna port and the beam corresponding to the second antenna port.

[0318] As mentioned earlier, the configuration information can be used to configure the first quasi-co-address relationship. There are multiple configuration methods, such as method a1 or method a2:

[0319] Method a1: The configuration information may include a first quasi-co-address relationship; accordingly, the first device may determine the first quasi-co-address relationship based on the configuration information.

[0320] Optionally, the configuration information may include a first quasi-co-address relationship, which can be understood as: the first field in the configuration information may include the type of the first quasi-co-address relationship. The first field may be a field indicating the quasi-co-address relationship.

[0321] For example, configuration information may include a TCI-state, which can be used to indicate a first quasi-co-address relationship. A possible example of a TCI-state is shown below:

[0322]

[0323] Here, tci-StateId represents the identifier (ID) of the current TCI-state, and qcl-Type3 may contain QCL-info, which can be used to indicate the first quasi-co-address relationship. For example, the format of QCL-info is as follows:

[0324]

[0325] Wherein, cell indicates which cell the quasi-co-location source channel or signal is in; bwp-Id indicates which bandwidth part (BWP) the quasi-co-location source channel or signal is located in; qcl-Type indicates the first quasi-co-location relationship. For example, when qcl-Type is typeE, the first quasi-co-location relationship is a first-type quasi-co-location relationship. As another example, when qcl-Type is typeF, the first quasi-co-location relationship is a second-type quasi-co-location relationship.

[0326] In some implementations, where a reference signal for communication is transmitted between the first antenna port and the second antenna port, and this reference signal can be used for sensing, the configuration information may further include a third quasi-co-location relationship. The third quasi-co-location relationship is a quasi-co-location relationship between the first antenna port and the second antenna port for communication. Exemplarily, the third quasi-co-location relationship is at least one of the following: QCL type A, QCL type B, QCL type C, or QCL type D. The specific details of QCL type A, QCL type B, QCL type C, and QCL type D can be found in the explanations of the terms above, and will not be repeated here.

[0327] For example, the configuration information may be reference signal resource configuration information (RS-ResourceConfig), which can be used to configure a first quasi-co-location relationship and a third quasi-co-location relationship. For instance, the reference signal resource configuration information may be CSI-RS resource configuration information (CSI-RS-ResourceConfig), which may include:

[0328] CSI-RS-ResourceConfig

[0329] bwp-ID

[0330] resourceType{aperiodic,semi-persistent,periodic}

[0331] CSI-RS-ResourceSet

[0332] Resource 1

[0333] Comm QCL Type info:{resource index,qcl-type}

[0334] Sensing QCL Type info:{resource index,qcl-type}

[0335] Among them, bwp-Id indicates which BWP the source channel or signal of the quasi-co-location relationship is located in; resourceType is used to indicate the type of resource (including aperiodic, semi-persistent, or periodic); Comm QCL Type info can be used to indicate the third quasi-co-location relationship, and the indication method is not limited, for example, it can be indicated in the way specified by the protocol; Sensing QCL Type info can be used to indicate the first quasi-co-location relationship, for example, the first quasi-co-location relationship can be indicated by TCI-state mentioned above.

[0336] This implementation can be sensed using a reference signal for communication without incurring additional resource overhead.

[0337] In other implementations, where the first and second antenna ports are used to transmit reference signals dedicated to sensing, the configuration information includes only the first quasi-co-address relationship.

[0338] For example, the configuration information may be reference signal resource configuration information, which can be used to configure a first quasi-co-address relationship. For instance, the reference signal resource configuration information may be sensing RS resource configuration information (sensing-RS-ResourceConfig), which may include:

[0339] sensing-RS-ResourceConfig

[0340] bwp-ID

[0341] resourceType{aperiodic,semi-persistent,periodic}

[0342] sensing-RS-ResourceSet

[0343] Resource 1

[0344] QCL Type info:{resource index,qcl-type}

[0345] Among them, bwp-Id indicates which BWP the quasi-co-location source channel or signal is located in; resourceType is used to indicate the type of resource (including aperiodic, semi-persistent, or periodic); QCL Type info can be used to indicate the first quasi-co-location relationship, for example, the first quasi-co-location relationship can be indicated by TCI-state mentioned above.

[0346] Through this method a1, the first device can accurately determine the first quasi-co-location relationship based on the configuration information.

[0347] Method a2: The configuration information can be used to configure a second quasi-co-location relationship, which is a quasi-co-location relationship for communication between the first antenna port and the second antenna port. The second quasi-co-location relationship corresponds to the first quasi-co-location relationship. Accordingly, the first device can determine the second quasi-co-location relationship according to the configuration information, and determine the first quasi-co-location relationship according to the correspondence between the second quasi-co-location relationship and the first quasi-co-location relationship.

[0348] Optionally, the second quasi-co-location relationship may include: the spatial reception parameters corresponding to the first antenna port are the same as the spatial reception parameters corresponding to the second antenna port. In other words, the type of the second quasi-co-location relationship may be QCL type D. The specific content of QCL type D can be found in the explanation of QCL type D in the above explanation of terms, and will not be repeated here. The first quasi-co-location relationship may be a second type of quasi-co-location relationship.

[0349] For example, the configuration information may be reference signal resource configuration information, which can be used to configure a second quasi-co-location relationship, corresponding to a first quasi-co-location relationship. For instance, the reference signal resource configuration information may be CSI-RS-ResourceConfig, which may include:

[0350] CSI-RS-ResourceConfig

[0351] bwp-ID

[0352] resourceType{aperiodic,semi-persistent,periodic}

[0353] CSI-RS-ResourceSet

[0354] Resource 1

[0355] Comm QCL Type info: QCL type D

[0356] Here, `bwp-Id` indicates which BWP the quasi-co-location source channel or signal is located in; `resourceType` indicates the type of resource (including aperiodic, semi-persistent, or periodic); `Comm QCL Type info` can be used to indicate a second quasi-co-location relationship, and the method of indication is not limited, for example, it can be indicated in a way specified by the protocol. When `Comm QCL Type info` indicates a second quasi-co-location relationship, `Comm QCL Type info` can implicitly indicate a first quasi-co-location relationship. For example, when `Comm QCL Type info` indicates QCL type D, `Comm QCL Type info` can implicitly indicate a second type of quasi-co-location relationship.

[0357] Through this method a2, the first device can accurately determine the first quasi-co-address relationship based on the configuration information. Furthermore, in this method, the configuration information can indirectly configure the first quasi-co-address relationship by configuring the second quasi-co-address relationship. The configuration information may not include the first quasi-co-address relationship, thereby reducing signaling overhead.

[0358] In some possible ways, the configuration information can also be used to configure how the first device processes the first sensing measurement result and the second sensing measurement result. The specific details of the first device can be found in the description of the first device in S801, and will not be repeated here. The first sensing measurement result is the sensing measurement result corresponding to the first reference signal, which can be a signal transmitted through the first antenna port. For example, the first reference signal can be a signal sent by the second device through the first antenna port. The second sensing measurement result is the sensing measurement result corresponding to the second reference signal, which can be a signal transmitted through the second antenna port. For example, the second reference signal can be a signal sent by the second device through the second antenna port.

[0359] Optionally, the configuration information can also be used to configure the processing method of the first device for the first sensing measurement result and the second sensing measurement result, which can be replaced by: the configuration information can also be used to configure the processing method of the first device for the sensing measurement result corresponding to the first antenna port and the sensing measurement result corresponding to the second antenna port.

[0360] The following methods b1 to b3 illustrate several possible examples of "the configuration information can also be used to configure how the first device processes the first sensing measurement result and the second sensing measurement result".

[0361] Method b1: The configuration information can be used to configure the first device to process the first sensing measurement result and the second sensing measurement result respectively.

[0362] Optionally, the first device processes the first sensing measurement result and the second sensing measurement result separately, which can be replaced by at least one of the following: the first device does not merge the first sensing measurement result and the second sensing measurement result; the first device processes the first sensing measurement result and the second sensing measurement result independently; or, the first device skips the merging process of the first sensing measurement result and the second sensing measurement result.

[0363] For example, the configuration information may be reference signal resource configuration information, which can be used to configure the first device to process the first sensing measurement result and the second sensing measurement result respectively. For instance, the reference signal resource configuration information may be CSI-RS-ResourceConfig, which may include:

[0364] CSI-RS-ResourceConfig

[0365] CSI-ProcessingConfig

[0366] Non-aggregation

[0367] The CSI-ProcessingConfig can be used to configure how the first device processes the first and second sensing measurement results. When the CSI-ProcessingConfig includes Non-aggregation, the processing method of the first device for the first and second sensing measurement results includes: the first device processes the first and second sensing measurement results separately; in other words, Non-aggregation can be used to configure the first device to process the first and second sensing measurement results separately.

[0368] Method b2: The configuration information is also used to configure the first device to perform coherent merging processing on the first sensing measurement results and the second sensing measurement results.

[0369] For example, the configuration information may be reference signal resource configuration information, which can be used to configure the first device to perform coherent merging processing on the first sensing measurement result and the second sensing measurement result. For instance, the reference signal resource configuration information may be CSI-RS-ResourceConfig, which may include:

[0370] CSI-RS-ResourceConfig

[0371] CSI-ProcessingConfig

[0372] UE coherent aggregation

[0373] The CSI-ProcessingConfi can be used to configure how the first device processes the first and second sensing measurement results. When the CSI-ProcessingConfi includes UE coherent aggregation, the processing method of the first device for the first and second sensing measurement results includes: the first device performing coherent merging processing on the first and second sensing measurement results; in other words, UE coherent aggregation can be used to configure the first device to perform coherent merging processing on the first and second sensing measurement results.

[0374] Method b3: The configuration information is also used to configure the first device to perform incoherent merging processing on the first sensing measurement result and the second sensing measurement result.

[0375] For example, the configuration information may be reference signal resource configuration information, which can be used to configure the first device to perform noncoherent merging processing on the first sensing measurement result and the second sensing measurement result. For instance, the reference signal resource configuration information may be CSI-RS-ResourceConfig, which may include:

[0376] CSI-RS-ResourceConfig

[0377] CSI-ProcessingConfig

[0378] UE non-coherent aggregation

[0379] The CSI-ProcessingConfi can be used to configure how the first device processes the first and second sensing measurement results. When the CSI-ProcessingConfi includes UE non-coherent aggregation, the processing method of the first device for the first and second sensing measurement results includes: the first device performs non-coherent merging processing on the first and second sensing measurement results; in other words, UE non-coherent aggregation can be used to configure the first device to perform non-coherent merging processing on the first and second sensing measurement results.

[0380] In some possible ways, the processing method of the first sensing measurement result may be related to the first quasi-co-address relationship, wherein the processing method of the first sensing measurement result may be the processing method of the first device for the first sensing measurement result and the second sensing measurement result configured by the configuration information.

[0381] In some implementations, when the first quasi-co-location relationship is a first type of quasi-co-location relationship, the processing method of the first sensing measurement result can be: the first device processes the first sensing measurement result and the second sensing measurement result respectively, that is, the configuration information can be used to configure the first device to process the first sensing measurement result and the second sensing measurement result respectively.

[0382] For example, the configuration information may be reference signal resource configuration information, which may include:

[0383] QCL Type info:{resource index,qcl-type E}

[0384] …

[0385] CSI-ProcessingConfig

[0386] Non-aggregation

[0387] The QCL Type info can be used to configure the first quasi-co-location relationship. The resource index is used to indicate the resource corresponding to the first quasi-co-location relationship. qcl-type E can be used to configure the first quasi-co-location relationship as a first type of quasi-co-location relationship. CSI-ProcessingConfi can be used to configure how the first device processes the first sensing measurement results and the second sensing measurement results. When CSI-ProcessingConfi includes Non-aggregation, the processing method of the first device for the first sensing measurement results and the second sensing measurement results includes: the first device processes the first sensing measurement results and the second sensing measurement results separately; in other words, Non-aggregation can be used to configure the first device to process the first sensing measurement results and the second sensing measurement results separately.

[0388] Optionally, when the first quasi-colocation relationship is a first type of quasi-colocation relationship, the first device (or the first equipment) is not expected to be configured to: perform coherent merging processing on the first sensing measurement result and the second sensing measurement result; or, perform incoherent merging processing on the first sensing measurement result and the second sensing measurement result.

[0389] In other implementations, when the first quasi-co-location relationship is a second type of quasi-co-location relationship, the processing method of the first sensing measurement result can be one of the following: the first device processes the first sensing measurement result and the second sensing measurement result respectively, that is, the configuration information is used to configure the first device to process the first sensing measurement result and the second sensing measurement result respectively; the first device performs coherent merging processing on the first sensing measurement result and the second sensing measurement result, that is, the configuration information is used to configure the first device to perform coherent merging processing on the first sensing measurement result and the second sensing measurement result; or, the first device performs incoherent merging processing on the first sensing measurement result and the second sensing measurement result, that is, the configuration information is used to configure the first device to perform incoherent merging processing on the first sensing measurement result and the second sensing measurement result.

[0390] For example, the configuration information may be reference signal resource configuration information, which may include:

[0391] QCL Type info:{resource index,qcl-type F}

[0392] …

[0393] CSI-ProcessingConfig

[0394] Non-aggregation,or UE coherent aggregation,or UE non-coherentaggregation

[0395] The QCL Type info can be used to configure a first quasi-co-location relationship. The resource index is used to indicate the resources corresponding to the first quasi-co-location relationship. qcl-type F can be used to configure the first quasi-co-location relationship as a second type of quasi-co-location relationship. CSI-ProcessingConfi can be used to configure the processing method of the first device for the first and second sensing measurement results. When CSI-ProcessingConfi includes Non-aggregation, the processing method of the first device for the first and second sensing measurement results includes: the first device processes the first and second sensing measurement results separately; in other words, Non-aggregation can be used to configure the first device to process the first and second sensing measurement results separately. When CSI-ProcessingConfi includes UE coherent aggregation, the processing method of the first device for the first and second sensing measurement results includes: the first device performs coherent merging processing on the first and second sensing measurement results; in other words, UE coherent aggregation can be used to configure the first device to perform coherent merging processing on the first and second sensing measurement results. In the case of CSI-ProcessingConfi including UE non-coherent aggregation, the processing method of the first device for the first sensing measurement result and the second sensing measurement result includes: the first device performs non-coherent merging processing on the first sensing measurement result and the second sensing measurement result; in other words, UE non-coherent aggregation can be used to configure the first device to perform non-coherent merging processing on the first sensing measurement result and the second sensing measurement result.

[0396] In some possible approaches, the processing method of the first sensing measurement result is related to the capability of the first device; correspondingly, the second device can determine the processing method of the first sensing measurement result based on the capability of the first device. The processing method of the first sensing measurement result may be the processing method of the first and second sensing measurement results configured by the configuration information. Optionally, the capability of the first device may be determined by the second device based on the capability information in S801.

[0397] Optionally, Table 2 shows a possible correspondence between the processing method of the sensing measurement results and the capabilities of the first device.

[0398] For example, when the first device supports coherent merging of sensing measurement results corresponding to multiple antenna ports, the processing method of the first sensing measurement result can be one of the following: the first device processes the first sensing measurement result and the second sensing measurement result separately, that is, the configuration information is used to configure the first device to process the first sensing measurement result and the second sensing measurement result separately; the first device performs coherent merging of the first sensing measurement result and the second sensing measurement result, that is, the configuration information is used to configure the first device to perform coherent merging of the first sensing measurement result and the second sensing measurement result; or, the first device performs incoherent merging of the first sensing measurement result and the second sensing measurement result, that is, the configuration information is used to configure the first device to perform incoherent merging of the first sensing measurement result and the second sensing measurement result.

[0399] For example, when the first device supports noncoherent merging of sensing measurement results corresponding to multiple antenna ports, the processing method for the first sensing measurement result may be one of the following: the first device processes the first sensing measurement result and the second sensing measurement result separately, i.e., the configuration information is used to configure the first device to process the first sensing measurement result and the second sensing measurement result separately; or, the first device performs noncoherent merging of the first sensing measurement result and the second sensing measurement result, i.e., the configuration information is used to configure the first device to perform noncoherent merging of the first sensing measurement result and the second sensing measurement result. And / or, when the first device supports noncoherent merging of sensing measurement results corresponding to multiple antenna ports, the first device (or the first device) does not expect to be configured to perform coherent merging of the first sensing measurement result and the second sensing measurement result.

[0400] For example, if the first device does not support coherent combining of sensing measurement results corresponding to multiple antenna ports, the processing method for the first sensing measurement result may be one of the following: the first device processes the first sensing measurement result and the second sensing measurement result separately, i.e., the configuration information is used to configure the first device to process the first sensing measurement result and the second sensing measurement result separately; or, the first device performs non-coherent combining of the first sensing measurement result and the second sensing measurement result, i.e., the configuration information is used to configure the first device to perform non-coherent combining of the first sensing measurement result and the second sensing measurement result. And / or, if the first device does not support coherent combining of sensing measurement results corresponding to multiple antenna ports, the first device (or the first device itself) does not expect to be configured to perform coherent combining of the first sensing measurement result and the second sensing measurement result.

[0401] For example, if the first device does not support incoherent merging of sensing measurement results corresponding to multiple antenna ports, the first sensing measurement result processing method may be: the first device processes the first sensing measurement result and the second sensing measurement result separately, that is, the configuration information is used to configure the first device to process the first sensing measurement result and the second sensing measurement result separately. And / or, if the first device does not support incoherent merging of sensing measurement results corresponding to multiple antenna ports, the first device (or the first device itself) does not expect to be configured to perform incoherent merging of the first sensing measurement result and the second sensing measurement result.

[0406] It should be noted that Table 2 above is merely an illustrative example and should not be construed as limiting the embodiments of this application. Any reasonable modifications, additions, or deletions to the content of Table 2 that result in new table content fall within the protection scope of the embodiments of this application.

[0407] In this way, the second device can configure the first device with a sensing measurement result processing method that is appropriate to its capabilities, thereby improving the effectiveness of the configuration.

[0408] In some possible ways, the configuration information can also be used to configure how the first device reports the sensing measurement results. Methods c1 to c4 below illustrate possible examples of "the configuration information can also be used to configure how the first device reports the sensing measurement results".

Wherein, reporting separately can be replaced by independent reporting.

[0411] For example, the configuration information may include reporting configuration information (ReportConfig), which can be used to configure the first device to report the first sensing measurement result and the second sensing measurement result respectively. For instance, the reporting configuration information may be channel state information (CSI) reporting configuration information (CSI-ReportConfig), which includes:

When `reportQuantity` includes `phase per port`, the first device reports the phase corresponding to each antenna port; in other words, `phase per port` can be used to configure the first device to report the phase corresponding to each antenna port.

[0431] Method c2: The configuration information is also used to configure the first device to report the third sensing measurement result, which is obtained by coherently merging the first sensing measurement result and the second sensing measurement result.

[0432] Optionally, the reporting of the third sensing measurement result by the first device can be replaced by at least one of the following: the first device reporting a coherent combining result; the first device reporting a sensing measurement result after coherent combining processing; or, the first device reporting a first processing result, which is obtained by coherently combining the sensing measurement results corresponding to multiple antenna ports. The specific content of the first processing result can be found in the description of the first processing result in S801, and will not be repeated here.

When `reportQuantity` includes `sensingMeasurement coherent aggregation`, the first device can report sensing measurement results in the following ways: the first device reports third sensing measurement results; in other words, `sensingMeasurement coherent aggregation` can be used to configure the first device to report third sensing measurement results.

[0438] Method c3: The configuration information is also used to configure the first device to report the fourth sensing measurement result, which is obtained by non-coherently merging the first sensing measurement result and the second sensing measurement result.

[0445] Method c4: The configuration information is also used to configure the first device to report the fifth perception measurement result, which is obtained by merging the first perception measurement result and the second perception measurement result.

[0446] Optionally, the first device reporting the fifth sensing measurement result can be replaced by: the first device reporting a merged result; the first device reporting a merged sensing measurement result; or, the first device reporting a third processing result, which is obtained by merging the sensing measurement results corresponding to multiple antenna ports. For example, the multiple antenna ports include a first antenna port and a second antenna port; the third processing result includes the fifth sensing measurement result.

[0451] The `reportQuantity` parameter can be used to configure how the first device reports the sensing measurement results. When `reportQuantity` includes `sensingMeasurement combination`, the first device can report the sensing measurement results in the following ways: the first device reports the fifth sensing measurement result; in other words, `sensingMeasurementcombination` can be used to configure the first device to report the fifth sensing measurement result.

[0452] In some possible ways, the first sensing measurement result reporting method may be related to the first quasi-co-address relationship, wherein the first sensing measurement result reporting method may be the method by which the first device reports sensing measurement results as configured in the configuration information.

[0453] In some implementations, when the first quasi-co-location relationship is a first type of quasi-co-location relationship, the reporting method of the first sensing measurement result can be: the first device reports the first sensing measurement result and the second sensing measurement result respectively, that is, the configuration information can be used to configure the first device to report the first sensing measurement result and the second sensing measurement result respectively.

[0456] Specifically, QCL Type info can be used to configure the first quasi-co-location relationship. Resource index can be used to indicate the resource corresponding to the first quasi-co-location relationship. qcl-type E can be used to configure the first quasi-co-location relationship as a first-type quasi-co-location relationship. reportQuantity can be used to configure how the first device reports sensing measurement results. When reportQuantity includes sensingMeasurement per port, the first device reports sensing measurement results in the following ways: the first device reports the first sensing measurement result and the second sensing measurement result separately; in other words, sensingMeasurement per port can be used to configure the first device to report the first sensing measurement result and the second sensing measurement result separately.

[0457] Optionally, when the first quasi-colocation relationship is a first type of quasi-colocation relationship, the first device (or first equipment) is not expected to be configured to: report a third sensing measurement result, which is obtained by coherently merging the first sensing measurement result and the second sensing measurement result; report a fourth sensing measurement result, which is obtained by incoherently merging the first sensing measurement result and the second sensing measurement result; or, report a fifth sensing measurement result, which is obtained by merging the first sensing measurement result and the second sensing measurement result.

[0458] In other implementations, when the first quasi-co-address relationship is a second type of quasi-co-address relationship, the reporting method of the first sensing measurement result can be one of the following: the first device reports the first sensing measurement result and the second sensing measurement result respectively, that is, the configuration information can be used to configure the first device to report the first sensing measurement result and the second sensing measurement result respectively; the first device reports the third sensing measurement result, that is, the configuration information is also used to configure the first device to report the third sensing measurement result; the first device reports the fourth sensing measurement result, that is, the configuration information is also used to configure the first device to report the fourth sensing measurement result; or, the first device reports the fifth sensing measurement result, that is, the configuration information is also used to configure the first device to report the fifth sensing measurement result.

[0459] For example, the configuration information may be reference signal resource configuration information, which may include:

[0460]

[0461] Specifically, `QCL Type info` can be used to configure the first quasi-co-location relationship. `resource index` can be used to indicate the resource corresponding to the first quasi-co-location relationship. `qcl-type F` can be used to configure the first quasi-co-location relationship as a second type of quasi-co-location relationship. `reportQuantity` can be used to configure how the first device reports sensing measurement results. When `reportQuantity` includes `sensingMeasurement per port`, the first device reports sensing measurement results in the following ways: the first device reports the first sensing measurement result and the second sensing measurement result respectively; in other words, `sensingMeasurement per port` can be used to configure the first device to report the first sensing measurement result and the second sensing measurement result respectively. When `reportQuantity` includes `sensingMeasurement coherent aggregation`, the first device reports sensing measurement results in the following ways: the first device reports the third sensing measurement result; in other words, `sensingMeasurement coherent aggregation` can be used to configure the first device to report the third sensing measurement result. When `reportQuantity` includes `sensingMeasurement non-coherent aggregation`, the first device reports sensing measurement results in the following ways: the first device reports the fourth sensing measurement result; in other words, `sensingMeasurement non-coherent aggregation` can be used to configure the first device to report the fourth sensing measurement result. When reportQuantity includes sensingMeasurement combination, the first device can report sensing measurement results in the following ways: the first device reports the fifth sensing measurement result; in other words, sensingMeasurementcombination can be used to configure the first device to report the fifth sensing measurement result.

[0462] In some possible approaches, the reporting method of the first sensing measurement result is related to the capability of the first device; correspondingly, the second device can determine the reporting method of the first sensing measurement result based on the capability of the first device. The reporting method of the first sensing measurement result can be the method configured in the configuration information for the first device to report sensing measurement results. Optionally, the capability of the first device can be determined by the second device based on the capability information in S801.

[0463] Optionally, Table 3 shows a possible correspondence between the reporting method of sensing measurement results and the capabilities of the first device.

[0464] For example, if the first device has multi-antenna port coherent combining feedback capability, the first sensing measurement result reporting method can be one of the following: the first device reports the third sensing measurement result, that is, the configuration information is used to configure the first device to report the third sensing measurement result; the first device reports the fourth sensing measurement result, that is, the configuration information is used to configure the first device to report the fourth sensing measurement result; or, the first device reports the first sensing measurement result and the second sensing measurement result respectively, that is, the configuration information is used to configure the first device to report the first sensing measurement result and the second sensing measurement result respectively.

[0465] For example, if the first device has multi-antenna port incoherent merging feedback capability, the first sensing measurement result reporting method may be one of the following: the first device reports a fourth sensing measurement result, i.e., the configuration information is used to configure the first device to report a fourth sensing measurement result; or, the first device reports the first sensing measurement result and the second sensing measurement result respectively, i.e., the configuration information is used to configure the first device to report the first sensing measurement result and the second sensing measurement result respectively. And / or, if the first device has multi-antenna port incoherent merging feedback capability, the first device (or the first equipment) does not expect to be configured to report a third sensing measurement result.

[0466] For example, if the first device supports the feedback of sensing measurement results corresponding to different antenna ports among multiple antenna ports, the reporting method of the first sensing measurement result can be: the first device reports the first sensing measurement result and the second sensing measurement result respectively, that is, the configuration information is used to configure the first device to report the first sensing measurement result and the second sensing measurement result respectively.

[0467] For example, if the first device does not have multi-antenna port coherent combining feedback capability, the first sensing measurement result reporting method may be one of the following: the first device reports a fourth sensing measurement result, i.e., the configuration information is used to configure the first device to report a fourth sensing measurement result; or, the first device reports the first sensing measurement result and the second sensing measurement result respectively, i.e., the configuration information is used to configure the first device to report the first sensing measurement result and the second sensing measurement result respectively. And / or, if the first device does not have multi-antenna port coherent combining feedback capability, the first device (or the first equipment) does not expect to be configured to report a third sensing measurement result.

[0468] For example, if the first device does not have multi-antenna port incoherent merging feedback capability, the first sensing measurement result reporting method may be: the first device reports the first sensing measurement result and the second sensing measurement result separately, that is, the configuration information is used to configure the first device to report the first sensing measurement result and the second sensing measurement result separately. And / or, if the first device does not have multi-antenna port incoherent merging feedback capability, the first device (or the first equipment) does not expect to be configured to report the fourth sensing measurement result.

[0469] For example, if the first device does not support the separate feedback of sensing measurement results corresponding to different antenna ports among multiple antenna ports, the first device (or the first equipment) is not expected to be configured to report the first sensing measurement result and the second sensing measurement result separately.

[0472]

[0473] It should be noted that Table 3 above is merely an illustrative example and should not be construed as limiting the embodiments of this application. Any reasonable modifications, additions, or deletions to the content of Table 3 that result in new table content fall within the protection scope of the embodiments of this application.

[0474] In this way, the second device can configure the first device to report sensing measurement results in a manner appropriate to its capabilities, thereby improving the effectiveness of the configuration. Furthermore, if the first device has multi-antenna port coherent combining feedback capability, the second device can configure the first device to report the coherently combined sensing measurement results. Compared to reporting the sensing measurement results for each antenna port separately, this reduces the amount of data transmitted between devices, lowers transmission overhead, and saves transmission resources. If the first device has multi-antenna port incoherent combining feedback capability, the second device can configure the first device to report incoherently combined sensing measurement results. Compared to reporting the sensing measurement results for each antenna port separately, this reduces the amount of data transmitted between devices, lowers transmission overhead, and saves transmission resources.

[0475] Configuration information can be carried in traditional messages or in new messages. For example, configuration information can be carried in RRC messages, MAC CE, or DCI messages.

[0476] The configuration information can have various names, such as control information, indication information, or RRC configuration information. As long as they have the same function, they are all within the scope of protection of this application.

[0477] S803: The second device sends a first reference signal; correspondingly, the first device receives the first reference signal.

[0478] The first reference signal is a reference signal transmitted through the first antenna port. For example, the first reference signal is a reference signal sent by the second device through the first antenna port.

[0479] For example, the second device can transmit a first reference signal in one beam direction; the first reference signal first reaches the sensing target #1 via wireless transmission, and then is reflected by the sensing target #1 to reach the second device, that is, the second device can receive the first reference signal, such as... Figure 8 S803a and S803b are shown in the figure. It should be understood that the reference signal can be transmitted from the first device to the second device through one or more transmission paths; only one is shown in the figure.

[0480] Optionally, the first device receiving the first reference signal can be replaced by: the first device receiving the echo signal of the first reference signal.

[0481] S804: The second device sends a second reference signal; correspondingly, the first device receives the second reference signal.

[0482] The second reference signal is a reference signal transmitted through the second antenna port. For example, the second reference signal is a reference signal sent by the second device through the second antenna port. The first and second reference signals can be used for sensing based on the first quasi-co-address relationship; correspondingly, the first device can perform sensing based on the first quasi-co-address relationship using the first and second reference signals.

[0483] For example, the second device can transmit a second reference signal in one beam direction; the second reference signal first reaches the sensing target #1 via wireless transmission, and then is reflected by the sensing target #1 to reach the second device, that is, the second device can receive the second reference signal, such as... Figure 8 S804a and S804b are shown in the figure. It should be understood that the reference signal can be transmitted from the first device to the second device through one or more transmission paths; only one is shown in the figure.

[0484] It should be understood that the sensing target corresponding to the first reference signal and the sensing target corresponding to the second reference signal may be the same or different. The figure illustrates this using the example where the sensing target corresponding to the first reference signal and the sensing target corresponding to the second reference signal are the same. For example, when the first quasi-co-address relationship is a first type of quasi-co-address relationship, the sensing target corresponding to the first reference signal and the sensing target corresponding to the second reference signal are different. As another example, when the first quasi-co-address relationship is a second type of quasi-co-address relationship, the sensing target corresponding to the first reference signal and the sensing target corresponding to the second reference signal may be the same or different.

[0485] Optionally, the first device receiving the first reference signal can be replaced by: the first device receiving the echo signal of the first reference signal.

[0486] This application does not limit the transmission order of the first reference signal and the second reference signal, that is, the order of S803 and S804 is not limited. For example, the second device may transmit the first reference signal first and then transmit the second reference signal. Alternatively, the second device may transmit the first reference signal and the second reference signal simultaneously.

[0487] In some implementations, the first quasi-co-address relationship is a first type of quasi-co-address relationship, and the first device can perform sensing based on a first reference signal and a second reference signal respectively. For example, the first device determines a first sensing measurement result corresponding to the first reference signal based on the first reference signal, and the first sensing measurement result includes a ranging result #1 for the sensing target #1. The first device determines a second sensing measurement result corresponding to the second reference signal based on the second reference signal, and the second sensing measurement result includes a ranging result #2 for the sensing target #2. The first device can perform sensing based on ranging result #1 and ranging result #2 respectively. As another example, the first device determines a first sensing measurement result corresponding to the first reference signal based on the first reference signal, and the first sensing measurement result includes a speed measurement result #1 for the sensing target #1. The first device determines a second sensing measurement result corresponding to the second reference signal based on the second reference signal, and the second sensing measurement result includes a speed measurement result #2 for the sensing target #2. The first device can perform sensing based on speed measurement result #1 and speed measurement result #2 respectively. The above examples can be independent or combined.

[0488] In other implementations, the first quasi-co-location relationship is a second type of quasi-co-location relationship, and the first sensing measurement result corresponding to the first reference signal and the second sensing measurement result corresponding to the second reference signal can be used for joint sensing. For example, the first device can determine the first sensing measurement result based on the first reference signal, the first sensing measurement result including a ranging result #1 for the sensing target #1. The first device can determine the second sensing measurement result based on the second reference signal, the second sensing measurement result including a ranging result #3 for the sensing target #1. The ranging result #1 and the ranging result #3 can be used to determine the distance to the sensing target #1. As another example, the first device can determine the first sensing measurement result based on the first reference signal, the first sensing measurement result including a velocity measurement result #1 for the sensing target #1. The first device can determine the second sensing measurement result based on the second reference signal, the second sensing measurement result including a velocity measurement result #3 for the sensing target #1. The velocity measurement result #1 and the velocity measurement result #3 can be used to determine the velocity of the sensing target #1. The above examples can be independent or combined.

[0489] Figure 8The method described defines (or introduces) a first quasi-co-location relationship for sensing among multiple antenna ports. This allows sensing measurements corresponding to these multiple antenna ports to be used for sensing based on this first quasi-co-location relationship, thereby improving sensing performance. For example, when the first quasi-co-location relationship is a second type of quasi-co-location relationship, the sensing measurements corresponding to multiple antenna ports can be used for joint sensing. Compared to sensing through sensing measurements corresponding to a single port, this method improves sensing performance, for example, it can improve sensing accuracy and / or precision.

[0490] Some possible ways (see) Figure 8 In implementation method one, when the first quasi-co-location relationship is a first type of quasi-co-location relationship, Figure 8 The method shown also includes S805:

[0491] S805: The first device sends the first information; correspondingly, the second device receives the first information.

[0492] The first information can be used to indicate the first sensing measurement result and the second sensing measurement result. The first sensing measurement result is the sensing measurement result corresponding to the first reference signal; the second sensing measurement result is the sensing measurement result corresponding to the second reference signal.

[0493] For example, the first device determines a first sensing measurement result corresponding to the first reference signal based on the first reference signal, the first sensing measurement result including a ranging result #1 for the sensing target #1. The first device determines a second sensing measurement result corresponding to the second reference signal based on the second reference signal, the second sensing measurement result including a ranging result #2 for the sensing target #2. The first information may include ranging result #1 and ranging result #2.

[0494] For example, the first device may determine a first sensing measurement result based on a first reference signal, the first sensing measurement result including a speed measurement result #1 for sensing target #1. The first device may determine a second sensing measurement result based on a second reference signal, the second sensing measurement result including a speed measurement result #2 for sensing target #2. The first information may include speed measurement result #1 and speed measurement result #2.

[0495] The examples above can be independent or combined with each other.

[0496] In this way, the second device can accurately determine the first sensing measurement result and the second sensing measurement result based on the first information.

[0497] In some implementations, when the configuration information is used to configure the first device to process the first sensing measurement result and the second sensing measurement result respectively, and / or when the configuration information is used to configure the first device to report the first sensing measurement result and the second sensing measurement result respectively, the first device can send first information; correspondingly, the second device receives the first information. The specific content of "the configuration information is used to configure the first device to process the first sensing measurement result and the second sensing measurement result respectively" can be referred to the description of method b1 in S802 above, and will not be repeated here; the specific content of "the configuration information is used to configure the first device to report the first sensing measurement result and the second sensing measurement result respectively" can be referred to the description of method c1 in S802 above, and will not be repeated here. Through this implementation, the first device can accurately determine the reporting method of the sensing measurement result based on the configuration information from the second device.

[0498] In other implementations, when the configuration information configures the first quasi-co-address relationship as a first type of quasi-co-address relationship, the first device can send the first information; correspondingly, the second device receives the first information. In this way, the configuration information does not need to be used to configure the processing method and reporting method of the first device for sensing measurement results, thereby reducing signaling overhead.

[0499] Optionally, after receiving the first information, the second device may process the first sensing measurement result and the second sensing measurement result separately. Alternatively, the processing of the first sensing measurement result and the second sensing measurement result separately by the second device may be replaced by at least one of the following: the second device may process the first sensing measurement result and the second sensing measurement result independently; the second device may not merge the first sensing measurement result and the second sensing measurement result; the second device may skip the merging process of the first sensing measurement result and the second sensing measurement result.

[0500] The first message can be carried in a traditional message or in a new message, without restriction. For example, the first message can be carried in an RRC message, a MAC CE, or a UCI.

[0501] The first information may also have other names, such as perception measurement result information or perception measurement result reporting information, etc., without restriction.

[0502] Alternatively, S805 can be after S803 and S804.

[0503] Some possible ways (see) Figure 8 In implementation method two, when the first quasi-co-location relationship is a second type of quasi-co-location relationship, Figure 8 The method shown also includes S806:

[0504] S806: The first device sends the second information; correspondingly, the second device receives the second information.

[0505] The second information is used to indicate the first sensing measurement result and the second sensing measurement result. The first sensing measurement result is the sensing measurement result corresponding to the first reference signal, and the second sensing measurement result is the sensing measurement result corresponding to the second reference signal.

[0506] For example, the first device may determine a first sensing measurement result based on a first reference signal, the first sensing measurement result including a ranging result #1 for the sensing target #1. The first device may determine a second sensing measurement result based on a second reference signal, the second sensing measurement result including a ranging result #3 for the sensing target #1. Second information may include ranging result #1 and ranging result #3. Ranging result #1 and ranging result #3 can be used to determine the distance to the sensing target #1.

[0507] For example, the first device may determine a first sensing measurement result based on a first reference signal, the first sensing measurement result including a speed measurement result #1 for the sensing target #1. The first device may determine a second sensing measurement result based on a second reference signal, the second sensing measurement result including a speed measurement result #3 for the sensing target #1. Second information may include speed measurement result #1 and speed measurement result #3. Speed ​​measurement result #1 and speed measurement result #3 can be used to sense the speed of the target #1.

[0508] The examples above can be independent or combined with each other.

[0509] In this way, the second device can accurately determine the first sensing measurement result and the second sensing measurement result based on the second information.

[0510] Optionally, the second information is further used to indicate: the first sensing measurement result corresponds to the first antenna port, and the second sensing measurement result corresponds to the second antenna port; and / or, the second information is further used to indicate the phase corresponding to the first antenna port and the phase corresponding to the second antenna port.

[0511] For example, the first device can determine a first sensing measurement result based on a first reference signal, the first sensing measurement result including a velocity measurement result #1 for the sensing target #1. The first device can determine a second sensing measurement result based on a second reference signal, the second sensing measurement result including a velocity measurement result #3 for the sensing target #1. The second information may include velocity measurement result #1 and velocity measurement result #3. In the port index field corresponding to velocity measurement result #1, the second information may also include the index of the first antenna port; in the port index field corresponding to velocity measurement result #3, the second information may also include the index of the second antenna port.

[0512] For example, the first device may determine a first sensing measurement result based on a first reference signal, the first sensing measurement result including a velocity measurement result #1 for the sensing target #1. The first device may determine a second sensing measurement result based on a second reference signal, the second sensing measurement result including a velocity measurement result #3 for the sensing target #1. The second information may include velocity measurement result #1 and velocity measurement result #3. In the phase field corresponding to velocity measurement result #1, the second information may further include the phase corresponding to the first antenna port; in the phase field corresponding to velocity measurement result #3, the second information may further include the phase corresponding to the second antenna port.

[0513] For example, the first device can determine a first sensing measurement result based on a first reference signal, the first sensing measurement result including a velocity measurement result #1 for the sensing target #1. The first device can determine a second sensing measurement result based on a second reference signal, the second sensing measurement result including a velocity measurement result #3 for the sensing target #1. The second information may include velocity measurement result #1 and velocity measurement result #3. In the port index field corresponding to velocity measurement result #1, the second information may also include the index of the first antenna port; in the port index field corresponding to velocity measurement result #3, the second information may also include the index of the second antenna port. In the phase field corresponding to velocity measurement result #1, the second information may also include the phase corresponding to the first antenna port; in the phase field corresponding to velocity measurement result #3, the second information may also include the phase corresponding to the second antenna port.

[0514] The above example uses speed measurement results as an illustration. It should be understood that speed measurement results can also be replaced by distance measurement results.

[0515] Using this method, the second device can determine the antenna port and / or the phase corresponding to the antenna port based on the second information, thereby merging the sensing measurement results corresponding to multiple antenna ports. Compared with sensing based on the sensing measurement results corresponding to a single port, this improves the sensing performance.

[0516] In some implementations, when the configuration information is used to configure the first device to process the first and second sensing measurement results respectively, and / or when the configuration information is used to configure the first device to report the first and second sensing measurement results respectively, the first device can send second information; correspondingly, the second device receives the second information. The specific content of "the configuration information is used to configure the first device to process the first and second sensing measurement results respectively" can be found in the description of method b1 in S802 above; the specific content of "the configuration information is used to configure the first device to report the first and second sensing measurement results respectively" can be found in the description of method c2 in S802 above, and will not be repeated here. Through this implementation, the first device can accurately determine the reporting method of the sensing measurement results based on the configuration information from the second device.

[0517] In other implementations, when the configuration information is used to configure the first device to perform coherent merging processing on the first sensing measurement result and the second sensing measurement result, and / or when the configuration information is used to configure the first device to report the third sensing measurement result, if the first device does not support at least one of the following: performing coherent merging processing on sensing measurement results corresponding to multiple antenna ports, or feeding back the first processing result, but the first device supports feeding back sensing measurement results corresponding to different antenna ports among multiple antenna ports respectively, then the first device sends the second information; correspondingly, the second device receives the second information. The specific details of "configuration information is used to configure the first device to perform coherent merging processing on the first sensing measurement result and the second sensing measurement result" can be found in the description of method b2 in S802 above; the specific details of "configuration information is used to configure the first device to report the third sensing measurement result" can be found in the description of method c2 in S802 above; the specific details of "the first device does not support coherent merging processing on sensing measurement results corresponding to multiple antenna ports" can be found in the description of "the first device does not support coherent merging processing on sensing measurement results corresponding to multiple antenna ports" in S801 above; the specific details of "the first device does not support feeding back the first processing result" can be found in the description of "the first device does not support feeding back the first processing result" in S801 above; the specific details of "the first device supports feeding back sensing measurement results corresponding to different antenna ports among multiple antenna ports" can be found in the description of "the first device supports feeding back sensing measurement results corresponding to different antenna ports among multiple antenna ports" in S801 above, and will not be repeated here. In simple terms, if the configuration information configures the first device to perform coherent merging processing and / or report the sensing measurement results of coherent merging processing, but the first device does not support coherent merging processing and / or does not support reporting the sensing measurement results of coherent merging processing, then the first device can fall back to reporting the sensing measurement results corresponding to each antenna port separately. In this implementation, if the processing method and / or reporting method of the sensing measurement results configured in the configuration information does not match the capabilities of the first device, the first device can fall back to reporting the sensing measurement results corresponding to each antenna port separately, thereby enabling sensing and reducing the impact on sensing performance.

[0518] In some implementations, when the configuration information is used to configure the first device to perform noncoherent merging processing on the first and second sensing measurement results, and / or when the configuration information is used to configure the first device to report the fourth sensing measurement result, if the first device does not support at least one of the following: performing noncoherent merging processing on sensing measurement results corresponding to multiple antenna ports, or feeding back the second processing result, but the first device supports feeding back sensing measurement results corresponding to different antenna ports among multiple antenna ports respectively, then the first device sends the second information; correspondingly, the second device receives the second information. The specific content of "configuration information is used to configure the first device to perform noncoherent merging processing on the first sensing measurement result and the second sensing measurement result" can be found in the description of method b3 in S802 above; the specific content of "configuration information is used to configure the first device to report the fourth sensing measurement result" can be found in the description of method c3 in S802 above; the specific content of "the first device does not support noncoherent merging processing on sensing measurement results corresponding to multiple antenna ports" can be found in the description of "the first device does not support noncoherent merging processing on sensing measurement results corresponding to multiple antenna ports" in S801 above; the specific content of "the first device does not support feeding back the second processing result" can be found in the description of "the first device does not support feeding back the second processing result" in S801 above; the specific content of "the first device supports feeding back sensing measurement results corresponding to different antenna ports among multiple antenna ports" can be found in the description of "the first device supports feeding back sensing measurement results corresponding to different antenna ports among multiple antenna ports" in S801 above, and will not be repeated here. In simple terms, if the configuration information configures the first device to perform incoherent merging processing and / or report the sensing measurement results of incoherent merging processing, but the first device does not support incoherent merging processing and / or does not support reporting the sensing measurement results of incoherent merging processing, then the first device can fall back to reporting the sensing measurement results corresponding to each antenna port separately. In this implementation, if the processing method and / or reporting method of the sensing measurement results configured in the configuration information does not match the capabilities of the first device, the first device can fall back to reporting the sensing measurement results corresponding to each antenna port separately, thereby enabling sensing and reducing the impact on sensing performance.

[0519] In some implementations, the first device can independently determine whether to send the first sensing measurement result and the second sensing measurement result. Optionally, the first device can determine whether to send the first sensing measurement result and the second sensing measurement result based on the capabilities of the first device. For example, if the first device supports feedback of sensing measurement results corresponding to different antenna ports among multiple antenna ports, the first device can determine whether to send the first sensing measurement result and the second sensing measurement result. Another example is if the computing power of the first device is less than a computing power threshold, the first device can determine whether to send the first sensing measurement result and the second sensing measurement result. The computing power threshold can be pre-set, such as as specified in the protocol; or it can be notified to the first device by other devices (e.g., the second device or core network equipment); or it can be determined by the first device. Through this implementation, the first device can independently determine the processing method and / or reporting method of the sensing measurement results. Thus, configuration information does not need to be used to configure the first device's processing method and reporting method of the sensing measurement results, thereby reducing signaling overhead.

[0520] In some implementations, the second information is also used to indicate that the reported sensing measurement results include the sensing measurement results corresponding to the first antenna port and the second antenna port, respectively. For example, if the first device decides to send the first sensing measurement results and the second sensing measurement results separately, or if the first device reverts to reporting the sensing measurement results corresponding to each antenna port separately, the second information is also used to indicate that the reported sensing measurement results include the sensing measurement results corresponding to the first antenna port and the second antenna port, respectively. In this way, the second device can accurately determine the reporting method of the sensing measurement results based on the second information.

[0521] Optionally, the second information is further used to indicate that the reported sensing measurement results include the sensing measurement results corresponding to the first antenna port and the second antenna port respectively, and can be replaced by at least one of the following: the second information is further used to indicate that the reported sensing measurement results are the sensing measurement results corresponding to each of the multiple antenna ports respectively; or, the second information is further used to indicate that the reported sensing measurement results are the sensing measurement results corresponding to different antenna ports respectively.

[0522] Optionally, the second information may include information a1 to information a3, where information a1 indicates the first sensing measurement result, information a2 indicates the second sensing measurement result, and information a3 indicates that the reported sensing measurement results include the sensing measurement results corresponding to the first antenna port and the second antenna port, respectively. Any two of information a1 to information a3 may be carried in the same or different messages, without limitation.

[0523] The second message can be carried in a traditional message or in a new message; there are no restrictions. For example, the second message can be carried in an RRC message, a MAC CE, or a UCI.

[0524] The second information may also have other names, such as sensing measurement result information or sensing measurement result reporting information, etc., without restriction.

[0525] Alternatively, S806 can be after S803 and S804.

[0526] Among some possible approaches, following S806, Figure 8 The method shown also includes S807:

[0527] S807: The second device merges the first sensing measurement result and the second sensing measurement result.

[0528] In some possible ways, the second device can coherently merge the first and second sensing measurement results to obtain a third sensing measurement result; correspondingly, the third sensing measurement result is obtained by coherently merging the first and second sensing measurement results.

[0529] Optionally, the third sensing measurement result is obtained by performing phase compensation on the first sensing measurement result and the second sensing measurement result, and then performing a first processing on the phase-compensated first sensing measurement result and the second sensing measurement result; correspondingly, the second device can execute steps A1 to A2:

[0530] Step A1: The second device performs phase compensation on the first sensing measurement result and the second sensing measurement result.

[0531] In some implementations, the P antenna ports include a first antenna port and a second antenna port. P is an integer greater than or equal to 2. The second device can use one of the P antenna ports as a reference antenna port to perform phase compensation on the sensing measurement results corresponding to each of the P antenna ports, thereby eliminating the fixed phase difference between different antenna ports in the P antenna ports, making the fixed phase difference between different antenna ports in the P antenna ports 0.

[0532] Optionally, the quasi-co-location relationship used for sensing between any two antenna ports in the P antenna ports is the first quasi-co-location relationship.

[0533] In some examples, the P antenna ports include only the first antenna port and the second antenna port. The second device can use the first antenna port as a reference to perform phase compensation on the sensing measurement results corresponding to the second antenna port, thereby eliminating the fixed phase difference between the first antenna port and the second antenna port, making the fixed phase difference between the first antenna port and the second antenna port 0.

[0534] In other examples, the P antenna ports include not only the first antenna port and the second antenna port, but also other antenna ports.

[0535] Optionally, the reference antenna port can be a first antenna port or a second antenna port, or the reference antenna port can be any of the P antenna ports other than the first and second antenna ports. Optionally, when the reference antenna port is the first antenna port, "the third sensing measurement result is obtained by performing phase compensation on the first and second sensing measurement results, and performing a first processing on the phase-compensated first and second sensing measurement results" can be replaced with: the third sensing measurement result is obtained by performing phase compensation on the second sensing measurement result, and performing a first processing on the first sensing measurement result and the phase-compensated second sensing measurement result; step A1 can be replaced with: the second device performs phase compensation on the second sensing measurement result; step A2 can be replaced with: the second device performs a first processing on the first sensing measurement result and the phase-compensated second sensing measurement result to obtain the third sensing measurement result.

[0536] The following example illustrates step A1.

[0537] For example, the sensing measurement result corresponding to the p-th antenna port among P antenna ports includes: the ranging result h corresponding to the p-th antenna port. p (r). p is a positive integer less than or equal to P. The reference antenna port is port 3000, and the phase difference between the p-th antenna port and port 3000 is Δψ. 01 The second device uses port 3000 as a reference to perform phase compensation on the ranging result corresponding to the p-th antenna port. The ranging result corresponding to the p-th antenna port after phase compensation is:

[0538] For example, the sensing measurement result corresponding to the p-th antenna port among P antenna ports includes: the speed measurement result h corresponding to the p-th antenna port. p (v). p is a positive integer less than or equal to P. The reference antenna port is port 3000, and the phase difference between the p-th antenna port and port 3000 is Δψ. 01 The second device uses port 3000 as a reference to perform phase compensation on the velocity measurement result corresponding to the p-th antenna port. The velocity measurement result corresponding to the p-th antenna port after phase compensation is:

[0539] It should be understood that the above examples can be independent or combined with each other.

[0540] Step A2: The second device performs a first processing on the first and second sensing measurement results after phase compensation to obtain the third sensing measurement result.

[0541] For example, the first processing can be one of the following: averaging, weighted averaging, maximum a posteriori probability processing, or maximum likelihood probability processing. The following example illustrates the first processing as averaging.

[0542] In some implementations, the P antenna ports include a first antenna port and a second antenna port. The specific details of the P antenna ports can be found in the description of the P antenna ports in step A1, and will not be repeated here. The second device can perform a first processing on the sensing measurement results corresponding to the phase-compensated P antenna ports to obtain a third sensing measurement result.

[0543] For example, the ranging result corresponding to the p-th antenna port after phase compensation is The third sensing measurement result may include the first ranging result, which is:

[0544] For example, the velocity measurement result corresponding to the p-th antenna port after phase compensation is: The third sensing measurement result may include the first speed measurement result, which is:

[0545] It should be understood that the above examples can be independent or combined with each other.

[0546] In some implementations, when two of the P antenna ports are coherent, the second device can perform coherent merging processing on the sensing measurement results corresponding to these two antenna ports. The specific details of the P antenna ports can be found in the description of the P antenna ports in step A1, and will not be repeated here. For example, when the first antenna port and the second antenna port are coherent, the second device can perform coherent merging processing on the first sensing measurement result and the second sensing measurement result.

[0547] The following section explains the coherence of the antenna port.

[0548] In some implementations, the sensing measurement result corresponding to the p-th antenna port out of P antenna ports includes the ranging result corresponding to the p-th antenna port. If the phase difference between the ranging results corresponding to two antenna ports out of P antenna ports varies linearly with distance, then these two antenna ports are coherent.

[0549] For example, such as Figure 10A As shown, different antenna ports among the P antenna ports can occupy different frequency domain resources, and each antenna port can correspond to a ranging result. The ranging result corresponding to the p-th antenna port is h. p (r). Where r is the distance, h p(r) represents the response of the p-th antenna port at a distance r, which can be a complex number. Since different antenna ports occupy different frequency domain resources, a specified frequency offset can exist between different antenna ports. For example, the P antenna ports include port 3000 and port 3001, and the frequency offset between port 3000 and port 3001 is Δf. 01 The phases of the ranging results corresponding to ports 3000 and 3001 are φ 3000 (r) and φ 3001 (r), φ 3000 (r) and φ 3001 The difference Δφ between (r) 01 (r) satisfies formula (1):

[0550] Δφ 01 (r)=2πΔf 01 r / c+Δψ 01 (1)

[0551] Formula (1) can be a linear equation. Where, Δf 01 and Δψ 01 Here, c is a fixed value (or a deterministic value), Δφ is the speed of light. 01 (r) changes as r changes. In Δφ 01 (r) Ports 3000 and 3001 are coherent when the distance changes linearly.

[0552] However, due to measurement errors, the phase difference between the ranging results at the two antenna ports may not satisfy a strictly linear relationship. For example, ... Figure 10B and Figure 10C As shown, the ranging results corresponding to the two antenna ports do not strictly fall on the first linear fitting curve, which is determined based on the ranging results corresponding to P antenna ports. A first error can be used to characterize the error between the ranging results corresponding to the two antenna ports and the first linear fitting curve. If the first error is less than or equal to a first error threshold, the two antenna ports are coherent. The first error threshold can be pre-set, such as as specified in a protocol; or it can be notified to the second device by other equipment (e.g., core network equipment); or it can be determined by the second device.

[0553] The first error can be determined based on error #1 and error #2. For example, the first error can be at least one of the following: the maximum or minimum value of error #1 and error #2, the average value of error #1 and error #2, the weighted average value of error #1 and error #2, the product of error #1 and error #2, the sum of the squares of error #1 and error #2, and the square root of the sum of the squares of error #1 and error #2. Here, error #1 can be the error between the ranging result corresponding to one of the two antenna ports and the first linear fitting curve, and error #2 can be the error between the ranging result corresponding to the other of the two antenna ports and the first linear fitting curve.

[0554] There are several ways to determine the error between the ranging result corresponding to each antenna port and the first linear fitting curve. The following will combine... Figure 10B and Figure 10C Here are some examples to illustrate this.

[0555] In some examples, the error between the ranging result corresponding to a certain antenna port and the first linear fitting curve can be the error between a first phase and a second phase. The first phase can be the phase corresponding to the measured value of the ranging result corresponding to the antenna port, and the second phase can be the phase in the first linear fitting curve corresponding to the first distance. The first distance can be the distance corresponding to the measured value of the ranging result corresponding to the antenna port. For example, as... Figure 10B As shown, the measured value of the ranging result corresponding to antenna port #1 can be represented by the rightmost hollow circle, and the phase corresponding to the rightmost hollow circle is phase #1; the distance corresponding to the rightmost hollow circle is r#1, the rightmost solid circle is the point on the first linear fitting curve corresponding to distance r#1, and the phase corresponding to the rightmost solid circle is phase #2. The error between the ranging result corresponding to antenna port #1 and the first linear fitting curve can be the error between phase #1 and phase #2.

[0556] In other examples, the error between the ranging result corresponding to a certain antenna port and the first linear fitting curve can be the vertical distance from the measured value of the ranging result at that antenna port to the first linear fitting curve. For example, as... Figure 10C As shown, the measured value of the ranging result corresponding to antenna port #1 is the rightmost hollow circle, the vertical distance from the rightmost hollow circle to the first linear fitting curve is d, and the error between the ranging result corresponding to antenna port #1 and the first linear fitting curve is d.

[0557] In other implementations, the sensing measurement result corresponding to the p-th antenna port out of P antenna ports includes the speed measurement result corresponding to the p-th antenna port. When the phase difference between the speed measurement results corresponding to two antenna ports out of P antenna ports changes linearly with speed, these two antenna ports are coherent.

[0558] For example, such as Figure 10D As shown, different antenna ports among the P antenna ports can occupy different time-domain resources, and each antenna port can correspond to a velocity measurement result. The velocity measurement result corresponding to the p-th antenna port is h. p (v). Where v is velocity, h p (v) represents the response of the p-th antenna port at velocity v, and this response is a complex number. If the resources corresponding to each antenna port repeat periodically in the time domain, then one antenna port can also be used for velocity measurement. Since different antenna ports occupy different time-domain resources, a specified time offset can exist between different antenna ports. For example, the P antenna ports include port 3000 and port 3001, and there is a fixed time offset Δt between port 3000 and port 3001. 01 The phases of the speed measurement results corresponding to ports 3000 and 3001 are φ. 3000 (v) and φ 3001 (v), φ 3000 (v) and φ 3001 The difference Δφ between (v) 01 (v) satisfies formula (2):

[0559] Δφ 01 (v)=2πΔt 01 v / λ+Δψ 01 (2)

[0560] Formula (2) can be a linear equation. Where Δt 01 and Δψ 01 For fixed values ​​(or deterministic values), c represents the speed of light, and Δφ 01 (v) changes as v changes. In Δφ 01 (v) Ports 3000 and 3001 are coherent when the speed changes linearly.

[0561] However, due to measurement errors, the phase difference between the velocity measurement results corresponding to the two antenna ports may not satisfy a strictly linear relationship. For example, as... Figure 10E and Figure 10FAs shown, the measured values ​​of the speed measurement results corresponding to the two antenna ports do not strictly fall on the second linear fitting curve, which is determined based on the measured values ​​of the speed measurement results corresponding to P antenna ports. A second error can be used to characterize the error between the speed measurement results corresponding to the two antenna ports and the second linear fitting curve. If the second error is less than or equal to a second error threshold, the two antenna ports are coherent. The second error threshold can be pre-set, such as as specified in the protocol; or it can be notified to the second device by other equipment (e.g., core network equipment); or it can be determined by the second device.

[0562] The second error can be determined based on errors #3 and #4. For example, the second error can be at least one of the following: the maximum or minimum value of errors #3 and #4, the average value of errors #3 and #4, the weighted average value of errors #3 and #4, the product of errors #3 and #4, the sum of the squares of errors #3 and #4, or the square root of the sum of the squares of errors #3 and #4. Here, error #3 can be the error between the speed measurement result corresponding to one of the two antenna ports and the second linear fitting curve, and error #4 can be the error between the speed measurement result corresponding to the other of the two antenna ports and the second linear fitting curve.

[0563] There are several ways to determine the error between the velocity measurement result corresponding to each antenna port and the second linear fitting curve. The following will combine... Figure 10E and Figure 10F Here are some examples to illustrate this.

[0564] In some examples, the error between the velocity measurement result corresponding to a certain antenna port and the second linear fitting curve can be the error between the third phase and the fourth phase. The third phase can be the phase corresponding to the measured value of the velocity measurement result corresponding to that antenna port, and the fourth phase can be the phase in the second linear fitting curve corresponding to the first velocity. The first velocity can be the velocity corresponding to the measured value of the velocity measurement result corresponding to that antenna port. For example, as... Figure 10E As shown, the measured value of the velocity result corresponding to antenna port #1 can be represented by the rightmost hollow circle, and the phase corresponding to the rightmost hollow circle is phase #3; the velocity corresponding to the rightmost hollow circle is v#1, and the rightmost solid circle is the point on the second linear fitting curve corresponding to velocity v#1, and the phase corresponding to the rightmost solid circle is phase #4. The error between the velocity measurement result corresponding to antenna port #1 and the second linear fitting curve can be the error between phase #3 and phase #4.

[0565] In other examples, the error between the velocity measurement result corresponding to a certain antenna port and the second linear fitting curve can be the vertical distance from the measured value of the velocity measurement result at that antenna port to the second linear fitting curve. For example, as... Figure 10F As shown, the measured value of the speed measurement result corresponding to antenna port #1 is the rightmost hollow circle, the vertical distance from the rightmost hollow circle to the second linear fitting curve is d, and the error between the speed measurement result corresponding to antenna port #1 and the second linear fitting curve is d.

[0566] In some implementations, the sensing measurement result corresponding to the p-th antenna port out of P antenna ports includes the ranging result and the velocity measurement result corresponding to the p-th antenna port. For details regarding whether two antenna ports out of P antenna ports are coherent, please refer to the explanation of antenna port coherence above, which will not be repeated here.

[0567] Optionally, in this implementation, different ports in the first part of the P antenna ports occupy different frequency domain resources, which can be used for ranging; different ports in the second part of the P antenna ports occupy different time domain resources, which can be used for speed measurement.

[0568] For example, such as Figure 10G As shown, the P antenna ports may include ports 3000 to 3003. Ports 3000 and 3001 occupy different frequency domain resources and can be used for ranging. For example, if the phase difference between the ranging results corresponding to ports 3000 and 3001 changes linearly with distance, the ranging results corresponding to ports 3000 and 3001 can be coherently combined. Ports 3000 and 3002 occupy different time domain resources and can be used for velocity measurement. For example, if the phase difference between the velocity measurement results corresponding to ports 3000 and 3002 changes linearly with velocity, the velocity measurement results corresponding to ports 3000 and 3002 can be coherently combined.

[0569] In this way, the second device can coherently combine the first and second sensing measurement results, thereby improving sensing performance. In some examples, when the first and second antenna ports occupy different frequency domain resources, coherently combining the first and second sensing measurement results can reduce the ranging grating lobes, increase the unambiguous ranging range, and improve the SNR. For example, when coherently combining the ranging results corresponding to P antenna ports, the SNR can be improved by approximately P times. In other examples, when the first and second antenna ports occupy different time domain resources, coherently combining the first and second sensing measurement results can reduce the velocity measurement grating lobes, increase the unambiguous velocity measurement range, and improve the SNR. For example, when coherently combining the velocity measurement results corresponding to P antenna ports, the SNR can be improved by approximately P times.

[0570] In some other possible approaches, the second device may perform incoherent merging of the first and second sensing measurement results.

[0571] In some implementations, the fourth sensing measurement result can be obtained by performing a second processing on the amplitudes of the first and second sensing measurement results; correspondingly, the second device can perform a second processing on the amplitudes of the first and second sensing measurement results to determine the fourth sensing measurement result. For example, the second processing can be one of the following: averaging, weighted averaging, maximum a posteriori probability processing, or maximum likelihood probability processing. The following example illustrates the second processing as averaging.

[0572] In some implementations, the P antenna ports include a first antenna port and a second antenna port. For details regarding the P antenna ports, please refer to the description of the P antenna ports in step A1, which will not be repeated here. The second device can perform a second processing on the amplitude of the sensing measurement results corresponding to the P antenna ports to obtain a fourth sensing measurement result.

[0573] For example, the ranging result corresponding to the p-th antenna port out of P antenna ports is h. p (r), the fourth sensing measurement result may include the second ranging result, the second ranging result being |h p (r)| represents h p The magnitude of (r).

[0574] For example, the velocity measurement result corresponding to the p-th antenna port out of P antenna ports is h. p (v) The fourth sensing measurement result may include the second speed measurement result, which is... |h p (v)| represents h p The magnitude of (v).

[0575] In other implementations, the fourth sensing measurement result is obtained by calibrating the first and second sensing measurement results, and then performing a second processing on the amplitudes of the calibrated first and second sensing measurement results. Correspondingly, the second device calibrates the first and second sensing measurement results, and then performs a second processing on the amplitudes of the calibrated first and second sensing measurement results to obtain the fourth sensing measurement result. The specific method by which the second device calibrates the first and second sensing measurement results is not limited; the specific content of "the second device performs a second processing on the amplitudes of the calibrated first and second sensing measurement results to obtain the fourth sensing measurement result" can be found in the above description of "the second device can perform a second processing on the amplitudes of the first and second sensing measurement results to determine the fourth sensing measurement result," except that the first sensing measurement result is replaced with the calibrated first sensing measurement result, and the second sensing measurement result is replaced with the calibrated second sensing measurement result.

[0576] In this way, the second device can perform noncoherent merging processing on the first and second sensing measurement results, thereby improving sensing performance. In some examples, when the first and second antenna ports occupy different frequency domain resources, noncoherent merging processing on the first and second sensing measurement results can improve the SNR. For example, when noncoherently merging the ranging results corresponding to P antenna ports, the SNR can be improved by approximately [percentage missing]. In other examples, where the first and second antenna ports occupy different time-domain resources, incoherently combining the first and second sensing measurement results can improve the SNR. For instance, by incoherently combining the velocity measurement results corresponding to P antenna ports, the SNR can be improved by approximately [percentage missing].

[0577] Some possible ways (see) Figure 8 In implementation method three, when the first quasi-co-location relationship is a second type of quasi-co-location relationship, Figure 8 The method shown also includes S808:

[0578] S808: The first device sends the third information; correspondingly, the second device receives the third information.

[0579] The third information is used to indicate the third sensing measurement result; correspondingly, the second device can determine the third sensing measurement result based on the third information. The third sensing measurement result is obtained by coherently merging the first sensing measurement result and the second sensing measurement result; correspondingly, the first device can perform coherent merging processing on the first sensing measurement result and the second sensing measurement result to obtain the third sensing measurement result.

[0580] Optionally, the specific content of "the third sensing measurement result is obtained by coherently merging the first sensing measurement result and the second sensing measurement result" can be found in the description of "the third sensing measurement result is obtained by coherently merging the first sensing measurement result and the second sensing measurement result" in S807, except that the second device is replaced by the first device, and will not be repeated here.

[0581] In this method, the first device can report the sensing measurement results after coherent merging. Compared with the sensing measurement results corresponding to each antenna port being fed back separately, this reduces the amount of data transmitted between devices, reduces transmission overhead, and saves transmission resources.

[0582] In some implementations, when the configuration information is used to configure the first device to perform coherent merging processing on the first and second sensing measurement results, and / or when the configuration information is used to configure the first device to report the third sensing measurement result, the first device sends third information; correspondingly, the second device receives the third information. The specific content of "configuration information for configuring the first device to perform coherent merging processing on the first and second sensing measurement results" can be found in the description of method b2 in S802 above; the specific content of "configuration information for configuring the first device to report the third sensing measurement result" can be found in the description of method c2 in S802 above, and will not be repeated here. Through this implementation, the first device can accurately determine the reporting method of the sensing measurement results based on the configuration information from the second device.

[0583] In other implementations, the first device can independently determine the reporting method for the third sensing measurement result. Optionally, the first device can determine the reporting method for the third sensing measurement result based on the capabilities of the first device. For example, if the first device supports coherent combining of sensing measurement results corresponding to multiple antenna ports, the first device can determine to report the third sensing measurement result. As another example, if the first device supports coherent combining of sensing measurement results corresponding to multiple antenna ports, and the computing power of the first device is greater than or equal to a computing power threshold, the first device can determine to report the third sensing measurement result. Through this implementation, the first device can independently determine the processing method and / or reporting method of the sensing measurement result. Thus, configuration information does not need to be used to configure the first device's processing method and reporting method for the sensing measurement result, thereby reducing signaling overhead.

[0584] In some implementations, the third information is also used to indicate that the reported sensing measurement results are obtained by coherently combining the sensing measurement results corresponding to the first antenna port and the second antenna port. For example, if the first device determines to report the third sensing measurement result, the third information is also used to indicate that the reported sensing measurement result is obtained by coherently combining the sensing measurement results corresponding to the first antenna port and the second antenna port. In this way, the second device can accurately determine the reporting method of the sensing measurement results based on the third information.

[0585] Optionally, the third information is further used to indicate that the reported sensing measurement result is obtained by coherently combining the sensing measurement result corresponding to the first antenna port and the sensing measurement result corresponding to the second antenna port, and can be replaced by at least one of the following: the third information is further used to indicate that the reported sensing measurement result is the result after coherent combining; or, the third information is further used to indicate that the reported sensing measurement result is obtained by coherently combining the sensing measurement results corresponding to multiple antenna ports.

[0586] Optionally, the third information may include information b1 and information b2, where information b1 indicates the third sensing measurement result, and information b2 indicates that the reported sensing measurement result is obtained by coherently combining the sensing measurement results corresponding to the first antenna port and the sensing measurement results corresponding to the second antenna port. Information b1 and information b2 may be carried in the same or different messages, without limitation.

[0587] Third-party information can be carried in traditional messages or in new messages, without restriction. For example, third-party information can be carried in RRC messages, MAC CE, or UCI messages.

[0588] The third information may also have other names, such as perception measurement result information or perception measurement result reporting information, and there are no restrictions.

[0589] Alternatively, S808 can be after S803 and S804.

[0590] Some possible ways (see) Figure 8 In implementation method four, when the first quasi-co-location relationship is a second type of quasi-co-location relationship, Figure 8 The method shown also includes S809:

[0591] S809: The first device sends the fourth information; correspondingly, the second device receives the fourth information.

[0592] The fourth information can be used to indicate the fourth sensing measurement result; correspondingly, the second device can determine the fourth sensing measurement result based on the fourth information. The fourth sensing measurement result is obtained by incoherently merging the first sensing measurement result and the second sensing measurement result; correspondingly, the first device can perform incoherent merging processing on the first sensing measurement result and the second sensing measurement result to obtain the fourth sensing measurement result.

[0593] Optionally, the specific content of "the fourth sensing measurement result is obtained by incoherently merging the first sensing measurement result and the second sensing measurement result" can be found in the description of "the fourth sensing measurement result is obtained by incoherently merging the first sensing measurement result and the second sensing measurement result" in S807, except that the second device is replaced by the first device, and will not be repeated here.

[0594] In this method, the first device can report the sensing measurement results after incoherent merging. Compared with the sensing measurement results corresponding to each antenna port being fed back separately, this reduces the amount of data transmitted between devices, reduces transmission overhead, and saves transmission resources.

[0595] In some implementations, when the configuration information is used to configure the first device to perform incoherent merging processing on the first and second sensing measurement results, and / or when the configuration information is used to configure the first device to report the fourth sensing measurement result, the first device sends fourth information; correspondingly, the second device receives the fourth information. The specific content of "configuration information for configuring the first device to perform incoherent merging processing on the first and second sensing measurement results" can be found in the description of method b3 in S802 above; the specific content of "configuration information for configuring the first device to report the fourth sensing measurement result" can be found in the description of method c3 in S802 above, and will not be repeated here. Through this implementation, the first device can accurately determine the reporting method of the sensing measurement results based on the configuration information from the second device.

[0596] In other implementations, when the configuration information is used to configure the first device to perform coherent merging processing on the first and second sensing measurement results, and / or when the configuration information is used to configure the first device to report the third sensing measurement result, if the first device does not support at least one of the following: coherent merging processing on sensing measurement results corresponding to multiple antenna ports, or feedback of the first processing result, but the first device supports incoherent merging processing on sensing measurement results corresponding to multiple antenna ports and supports feedback of the second processing result, then the first device sends fourth information; correspondingly, the second device receives the fourth information. The specific content of "configuration information is used to configure the first device to perform coherent merging processing on the first and second sensing measurement results" can be found in the description of method b2 in S802 above; the specific content of "configuration information is used to configure the first device to report the third sensing measurement result" can be found in the description of method c2 in S802 above; the specific content of "the first device does not support coherent merging processing on sensing measurement results corresponding to multiple antenna ports" can be found in the description of "the first device does not support coherent merging processing on sensing measurement results corresponding to multiple antenna ports" in S801 above. The specific details of "the first device does not support feedback of the first processing result" can be found in the explanation of "the first device does not support feedback of the first processing result" in S801 above; the specific details of "the first device supports incoherent combining processing of sensing measurement results corresponding to multiple antenna ports" can be found in the explanation of "the first device supports incoherent combining processing of sensing measurement results corresponding to multiple antenna ports" in S801 above; the specific details of "the first device supports feedback of the second processing result" can be found in the explanation of "the first device supports feedback of the second processing result" in S801 above, and will not be repeated here. In short, if the configuration information configures the first device to perform coherent combining processing and / or report sensing measurement results processed by coherent combining, and / or if the first device does not support coherent combining processing and / or does not support reporting sensing measurement results processed by coherent combining, then the first device can revert to incoherent combining processing and report the sensing measurement results processed by incoherent combining. In this implementation, if the processing method and / or reporting method of the sensing measurement results configured in the configuration information do not match the capabilities of the first device, the first device can fall back to reporting the sensing measurement results of non-coherent merging processing, thereby enabling sensing and reducing the impact on sensing performance.

[0597] In some implementations, the first device can independently determine which fourth sensing measurement result to report. Optionally, the first device can determine which fourth sensing measurement result to report based on the capabilities of the first device. For example, if the first device supports incoherent combining of sensing measurement results corresponding to multiple antenna ports, the first device can determine which fourth sensing measurement result to report. As another example, if the first device supports incoherent combining of sensing measurement results corresponding to multiple antenna ports, and the computing power of the first device is greater than or equal to a computing power threshold, the first device can determine which fourth sensing measurement result to report. Through this implementation, the first device can independently determine the processing method and / or reporting method of the sensing measurement result. Thus, configuration information does not need to be used to configure the first device's processing method and reporting method for the sensing measurement result, thereby reducing signaling overhead.

[0598] In some implementations, the fourth information is also used to indicate that the reported sensing measurement result is obtained by incoherently combining the sensing measurement result corresponding to the first antenna port and the sensing measurement result corresponding to the second antenna port. For example, if the first device determines to report the fourth sensing measurement result on its own, or if the first device reverts to reporting the sensing measurement result processed by incoherent merging, the fourth information is also used to indicate that the reported sensing measurement result is obtained by incoherently merging the sensing measurement result corresponding to the first antenna port and the sensing measurement result corresponding to the second antenna port. In this way, the second device can accurately determine the reporting method of the sensing measurement result based on the third information.

[0599] Optionally, the fourth information is further used to indicate that the reported sensing measurement result is obtained by incoherently combining the sensing measurement result corresponding to the first antenna port and the sensing measurement result corresponding to the second antenna port, which can be replaced by at least one of the following: the fourth information is further used to indicate that the reported sensing measurement result is the result after incoherent combining; or, the fourth information is further used to indicate that the reported sensing measurement result is obtained by incoherently combining the sensing measurement results corresponding to multiple antenna ports.

[0600] Optionally, the third information may include information c1 and information c2, where information c1 indicates the fourth sensing measurement result, and information c2 indicates that the reported sensing measurement result is obtained by incoherently combining the sensing measurement results corresponding to the first antenna port and the sensing measurement results corresponding to the second antenna port. Information c1 and information c2 may be carried in the same or different messages, without limitation.

[0601] The fourth message can be carried in a traditional message or in a new message, without restriction. For example, the fourth message can be carried in an RRC message, a MAC CE, or a UCI.

[0602] The fourth information may also have other names, such as perception measurement result information or perception measurement result reporting information, and there are no restrictions.

[0603] Alternatively, S809 can be after S803 and S804.

[0604] In this application, a quasi-co-location relationship for sensing may exist between one antenna port and one or more antenna ports.
