Description

Measurement reporting methods and related devices

[0001] This application claims priority to Chinese Patent Application No. 202411458328.8, filed on October 17, 2024, entitled "Measuring and Reporting Method and Related Apparatus", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communications, and more particularly to a measurement reporting method and related apparatus. Background Technology

[0003] For sensing services, multiple targets may exist in a real-world environment, and these targets may be located on different beams. The path loss of different targets typically varies. For example, when network devices and terminal devices cooperate in sensing, the farther the target is from the network device and / or terminal device, the greater the path loss. This can lead to significant differences in the reference signal receiving power (RSRP) measured by the terminal device on the beam where the target is located. The presence of a strong target may result in a higher RSRP measured on adjacent beams of the beam containing the strong target, and even the RSRP measured on the sidelobe beam of the strong target may be greater than the RSRP measured on the main lobe beam of the weak target.

[0004] In existing methods, terminal devices typically report valid beams to network devices based on RSRP measurements on different beams, such as reporting the top X beams with the highest RSRP. However, in multi-target sensing scenarios, due to interference from strong targets on weak targets, existing methods may cause network devices to fail to accurately identify the beam where the weak target is located. Summary of the Invention

[0005] This application provides a measurement reporting method and related apparatus, which helps to more accurately identify the beam in which the target is located.

[0006] In a first aspect, a measurement reporting method is provided, which can be executed by a first communication device. The first communication device can be a terminal device, a component configured in the terminal device (such as a processor, chip, or chip system), or a logic module or software that can realize all or part of the functions of the terminal device. This application does not limit the scope of the method.

[0007] The method includes: receiving reference signals on a plurality of beams; and transmitting first information, the first information being used to indicate at least one beam corresponding to each of at least one path, wherein the at least one beam corresponding to each path is at least one beam with the highest reference signal receiving path power on the plurality of beams, i.e., the top X beams with the highest reference signal receiving path power, where X is a positive integer.

[0008] It should be understood that "at least one path" refers to at least one propagation path of the reference signal on the plurality of beams in the environment. When the plurality of beams are measured in the Doppler domain and / or time delay domain, a path is represented by a power peak in the Doppler domain and / or time delay domain; in other words, the physical meaning of the power peak is a path.

[0009] Each of the multiple beams carries a reference signal, and the reference signals on different beams are used to sense targets in different directions.

[0010] The value of X can be the same or different for different paths. That is, for different paths, the same number of beams can be reported, or different numbers of beams can be reported.

[0011] Based on the technical solution of this application, the first communication device reports at least one beam corresponding to each of the at least one path. There is a priority among the at least one beams corresponding to the same path. The beam with higher power in the reference signal receiving path has a higher priority and may contain a target. However, there is no priority among the multiple beams corresponding to different paths. This is beneficial for distinguishing the sidelobe beams of strong targets and the main lobe beams of weak targets, thereby facilitating more accurate identification of the beam where the target is located in a multi-target scenario.

[0012] In conjunction with the first aspect, in some implementations of the first aspect, the plurality of beams includes a first beam, the at least one path includes a first path, and the reference signal received path power of the first path on the first beam is any one of the following: the received power of the reference signal on the first beam at the time delay-Doppler position where the first path is located; or, the received power of the reference signal on the first beam at the Doppler position where the first path is located; or, the received power of the reference signal on the first beam at the time delay position where the first path is located.

[0013] In conjunction with the first aspect, in some implementations of the first aspect, the first information is also used to indicate one or more of the following: the reference signal received path power of each path in each corresponding at least one beam, the time delay-Doppler position of each path, the Doppler position of each path, or the time delay position of each path. This facilitates a more accurate determination of the beam in which the target is located.

[0014] In conjunction with the first aspect, in some implementations of the first aspect, the first information is also used to indicate the sorting information or priority information of at least one beam corresponding to each path. This is beneficial for more accurately determining the beam in which the target is located.

[0015] In conjunction with the first aspect, in some implementations of the first aspect, the first information includes an identifier of each beam in at least one beam corresponding to each path, or includes an identifier of a reference signal on each beam in at least one beam corresponding to each path.

[0016] In conjunction with the first aspect, in some implementations of the first aspect, the method further includes: receiving second information, the second information being used to indicate the number of the at least one path, and / or the number of at least one beam corresponding to each path.

[0017] In this application, the first communication device may receive second information from the second communication device (e.g., access network equipment), or the first communication device may receive second information from the network element responsible for sensing functions in the core network.

[0018] In conjunction with the first aspect, in some implementations of the first aspect, the reference signal received path power of each path on each of the corresponding at least one beam is greater than the threshold corresponding to each path.

[0019] In this application, each of the at least one path corresponds to a threshold. The at least one threshold corresponding to each path can be the same or different; the differences can be all different or partially different. By using the threshold corresponding to each path, the number of beams reported for each path can be limited, which helps to reduce signaling overhead and computational complexity.

[0020] In conjunction with the first aspect, in some implementations of the first aspect, the threshold corresponding to each path is related to the time delay position of each path.

[0021] For example, the greater the time delay of a path, the smaller the threshold corresponding to that path; conversely, the smaller the time delay of a path, the greater the threshold corresponding to that path.

[0022] In conjunction with the first aspect, in some implementations of the first aspect, the method further includes: receiving third information, the third information being used to indicate the threshold corresponding to each path.

[0023] In this application, the first communication device may receive third information from the second communication device (e.g., access network equipment), or the first communication device may receive third information from the network element responsible for sensing functions in the core network.

[0024] In conjunction with the first aspect, in some implementations of the first aspect, the Doppler position of each path belongs to the first Doppler range, and / or, the time delay position of each path belongs to the first time delay range.

[0025] In this application, the first Doppler range and / or the first time delay range can be regarded as the expected time delay and / or Doppler of the sensing service on the target. The first communication device can perform sensing within the first Doppler range and / or the first time delay range, which helps to reduce the computational load of the first communication device and reduce power consumption.

[0026] In conjunction with the first aspect, in some implementations of the first aspect, the method further includes: receiving fourth information, the fourth information being used to indicate a first Doppler range, and / or a first time delay range.

[0027] In this application, the first communication device may receive fourth information from the second communication device (e.g., access network equipment), or the first communication device may receive fourth information from a network element in the core network responsible for sensing functions.

[0028] In conjunction with the first aspect, in some implementations of the first aspect, the first information is further used to indicate the similarity between the power spectrum of the second beam and the power spectrum of the third beam, wherein the second beam is any one of the at least one beams, and the third beam includes beams in the at least one beam whose reference signal receiving path power is higher than that of the second beam.

[0029] In this application, similarity is introduced as an indicator to determine the beam in which the target is located. The purpose is to identify whether a beam with high power in a reference signal receiving path is a sidelobe beam of a strong target or a main lobe beam of a weak target. The higher the similarity between the power spectrum of the second beam and the power spectrum of the third beam, the more likely the second beam is a sidelobe beam of a strong target on the third beam. This helps to more accurately determine the beam in which the target is located.

[0030] In conjunction with the first aspect, in some implementations of the first aspect, the third beam is an adjacent beam to the second beam.

[0031] In this application, since higher sidelobe power is more likely to be measured on a beam adjacent to the beam where the target is located, the first communication device can, for the second beam, only calculate the similarity between the power spectrum of the second beam and the power spectrum of a beam adjacent to the second beam that has a higher reference signal receiving path power than the second beam. This helps reduce the computational load of the first communication device and also helps reduce signaling overhead.

[0032] In conjunction with the first aspect, in some implementations of the first aspect, the method further includes: receiving fifth information, the fifth information being used to indicate adjacent beams of each of the plurality of beams.

[0033] In this application, the first communication device may receive fifth information from the second communication device (e.g., access network equipment), or the first communication device may receive fifth information from a network element in the core network responsible for sensing functions.

[0034] Secondly, a measurement reporting method is provided, which can be executed by a second communication device. The communication device can be a network device, a component configured in the network device (such as a processor, chip, or chip system), or a logic module or software that can realize all or part of the functions of the network device. This application does not limit the scope of the method.

[0035] The method includes: transmitting reference signals on a plurality of beams; and receiving first information, the first information indicating at least one beam corresponding to each of at least one path, wherein the at least one beam corresponding to each path is at least one beam with the highest reference signal receiving path power on the plurality of beams for each path.

[0036] It should be understood that "at least one path" refers to at least one propagation path of the reference signal on the plurality of beams in the environment. When the plurality of beams are measured in the Doppler domain and / or time delay domain, a path is represented by a power peak in the Doppler domain and / or time delay domain; in other words, the physical meaning of the power peak is a path.

[0037] Each of the multiple beams carries a reference signal, and the reference signals on different beams are used to sense targets in different directions.

[0038] Based on the technical solution of this application, the second communication device acquires at least one beam corresponding to each of the at least one path. There is a priority among the at least one beams corresponding to the same path. The beam with higher power in the reference signal receiving path has a higher priority and may contain a target. However, there is no priority among the multiple beams corresponding to different paths. This is beneficial for distinguishing the sidelobe beams of strong targets and the main lobe beams of weak targets, thereby facilitating more accurate identification of the beam where the target is located in a multi-target scenario.

[0039] In conjunction with the second aspect, in some implementations of the second aspect, the plurality of beams includes a first beam, the at least one path includes a first path, and the reference signal received path power of the first path on the first beam is any one of the following: the received power of the reference signal on the first beam at the time delay-Doppler position where the first path is located; or, the received power of the reference signal on the first beam at the Doppler position where the first path is located; or, the received power of the reference signal on the first beam at the time delay position where the first path is located.

[0040] In conjunction with the second aspect, in some implementations of the second aspect, the first information is also used to indicate one or more of the following: the reference signal received path power of each path in each corresponding at least one beam, the time delay-Doppler position of each path, the Doppler position of each path, or the time delay position of each path. This facilitates a more accurate determination of the beam in which the target is located.

[0041] In conjunction with the second aspect, in some implementations of the second aspect, the first information is also used to indicate the ordering or priority information of at least one beam corresponding to each path. This helps to more accurately determine the beam in which the target is located.

[0042] In conjunction with the second aspect, in some implementations of the second aspect, the first information includes the identifier of each beam in at least one beam corresponding to each path, or includes the identifier of the reference signal on each beam in at least one beam corresponding to each path.

[0043] In conjunction with the second aspect, in some implementations of the second aspect, the method further includes: sending second information, the second information being used to indicate the number of the at least one path, and / or the number of at least one beam corresponding to each path.

[0044] In conjunction with the second aspect, in some implementations of the second aspect, the reference signal received path power of each path on each of the corresponding at least one beam is greater than the threshold corresponding to each path.

[0045] In conjunction with the second aspect, in some implementations of the second aspect, the threshold corresponding to each path is related to the time delay position of each path.

[0046] In conjunction with the second aspect, in some implementations of the second aspect, the method further includes: sending third information, which is used to indicate the threshold corresponding to each path.

[0047] In conjunction with the second aspect, in some implementations of the second aspect, the Doppler position of each path belongs to the first Doppler range, and / or, the time delay position of each path belongs to the first time delay range.

[0048] In conjunction with the second aspect, in some implementations of the second aspect, the method further includes: sending fourth information, the fourth information being used to indicate the first Doppler range, and / or, the first time delay range.

[0049] In conjunction with the second aspect, in some implementations of the second aspect, the first information is also used to indicate the similarity between the power spectrum of the second beam and the power spectrum of the third beam, wherein the second beam is any one of the at least one beams, and the third beam includes beams in the at least one beam whose reference signal receiving path power is higher than that of the second beam.

[0050] In conjunction with the second aspect, in some implementations of the second aspect, the third beam is an adjacent beam to the second beam.

[0051] In conjunction with the second aspect, in some implementations of the second aspect, the method further includes: sending fifth information, the fifth information being used to indicate the adjacent beams of each of the plurality of beams.

[0052] It should be understood that the second aspect of this application corresponds to the technical solution of the first aspect of this application, and the beneficial effects achieved by each aspect and the corresponding feasible implementation are similar, and will not be repeated here.

[0053] Thirdly, a measurement reporting method is provided, which can be executed by a first communication device.

[0055] In this application, each of the multiple beams carries a reference signal, and the reference signals on different beams are used to sense targets in different directions.

[0056] The higher the similarity between the power spectrum of the fourth beam and the power spectrum of the fifth beam, the more likely the fourth beam is to be a sidelobe beam of a strong target on the fifth beam. In this case, the fourth beam is not included in the reported at least one beam. However, when the similarity between the power spectrum of the fourth beam and the power spectrum of the fifth beam is lower than the first threshold, the fourth beam may be included in the reported at least one beam. This helps to avoid the interference of the sidelobe beams of strong targets on the main lobe beams of weak targets, thereby facilitating a more accurate determination of the beam in which the target is located.

[0061] In this application, the first Doppler range and / or the first time delay range can be regarded as the expected time delay and / or Doppler of the sensing service on the target. The first communication device can perform sensing within the first Doppler range and / or the first time delay range, which helps to reduce the computational load of the first communication device and reduce power consumption.

[0062] In conjunction with the third aspect, in some implementations of the third aspect, the method further includes: receiving fourth information, the fourth information being used to indicate a first Doppler range, and / or a first time delay range.

[0064] In conjunction with the third aspect, in some implementations of the third aspect, the received power of the reference signal for each beam in the at least one beam is greater than a second threshold.

[0076] The higher the similarity between the power spectrum of the fourth beam and the power spectrum of the fifth beam, the more likely the fourth beam is to be a sidelobe beam of a strong target on the fifth beam. In this case, the fourth beam may not be reported. However, when the similarity between the power spectrum of the fourth beam and the power spectrum of the fifth beam is lower than the first threshold, the fourth beam may be reported. This helps to avoid the interference of the sidelobe beams of strong targets on the main lobe beams of weak targets, thus facilitating a more accurate determination of the beam in which the target is located.

[0087] In conjunction with the fourth aspect, in some implementations of the fourth aspect, the method further includes: sending fifth information, the fifth information being used to indicate the adjacent beams of each of the plurality of beams.

[0088] It should be understood that the fourth aspect of this application corresponds to the technical solution of the third aspect of this application, and the beneficial effects achieved by each aspect and the corresponding feasible implementation are similar, so they will not be repeated here.

[0089] Fifthly, a measurement reporting method is provided. This method can be executed by a first communication device, which can be a terminal device, a component configured in the terminal device (such as a processor, chip, or chip system), or a logic module or software that can realize all or part of the functions of the terminal device.

[0101] In conjunction with the fifth aspect, in some implementations of the fifth aspect, the eighth beam is the adjacent beam of the seventh beam.

[0102] In this application, since higher sidelobe power is more likely to be measured on beams adjacent to the beam where the target is located, for the seventh beam, the first communication device can simply calculate the similarity between the power spectrum of the seventh beam and the power spectrum of a beam adjacent to the seventh beam that has a higher received power than the reference signal of the seventh beam.

[0107] In this application, each of the multiple beams carries a reference signal, and the reference signals on different beams are used to sense targets in different directions.

[0108] Based on the technical solution of this application, while receiving the top X beams with the highest reference signal reception power among the multiple beams, the second communication device can also receive the similarity corresponding to each of the top X beams.

[0139] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0140] Before introducing the measurement reporting method and related apparatus provided in the embodiments of this application, the following points should be made first.

[0141] First, in the embodiments shown below, the terms and English abbreviations, such as reference signal received path power, Doppler spectrum, and reference signal received power (RSRP), are merely exemplary examples given for ease of description and should not constitute any limitation on this application. This application does not preclude the possibility of defining other terms that can achieve the same or similar functions in existing or future agreements.

[0142] Second, in the embodiments shown below, the terms "first," "second," and various numerical designations are merely for descriptive convenience to distinguish identical or similar items with substantially the same function and purpose. For example, "first information" and "second information" are only used to distinguish different information and do not limit their order, nor are they used to limit the scope of the embodiments of this application. Those skilled in the art will understand that the terms "first," "second," etc., do not limit the quantity or execution order, and that "first," "second," etc., are not necessarily different.

[0143] Third, "at least one" means one or more, while "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, and c can mean: a, or b, or c, or a and b, or a and c, or b and c, or a, b, and c, where a, b, and c can be single or multiple.

[0144] Fourth, in this application, "instruction" can include direct and indirect instructions, explicit and implicit instructions, and instructions used for determination. The information indicated by a certain piece of information (such as first information) is called the information to be instructed. For example, the first information in the embodiments of this application indicates one or more contents. In specific implementation, there are many ways to indicate the information to be instructed, such as, but not limited to, directly indicating the information to be instructed, such as the information to be instructed itself or its index. It can also indirectly indicate the information to be instructed by indicating other information, where there is a correlation between the other information and the information to be instructed; or it can only indicate a part of the information to be instructed, while the other parts are known or pre-agreed upon. For example, the instruction can be implemented by using a pre-agreed (e.g., protocol predefined) arrangement of various information, thereby reducing the instruction overhead to a certain extent. This application does not limit the specific method of instruction. It is understood that for the sender of the instruction information, the instruction information can be used to indicate the information to be instructed; for the receiver of the instruction information, the instruction information can be used to determine the information to be instructed.

[0145] The information in this application is used to indicate one or more contents, or it can be replaced by the information indicating one or more contents, or the information including one or more contents. For example, the first information is used to indicate at least one beam corresponding to each of at least one path, or it can be replaced by the first information indicating at least one beam corresponding to each of at least one path, or the first information including at least one beam corresponding to each of at least one path.

[0146] Fifth, in this application, "when," "if," and "if" all refer to the device taking corresponding actions under certain objective circumstances, not to a time limit, nor do they require the device to perform a judgment action, nor do they imply any other limitations. Unless otherwise specified, "if" and "if" are interchangeable, and "when" and "under the circumstances" are interchangeable. "When" is interchangeable with "if" / "if."

[0147] Sixth, in this application, the words "exemplarily" or "for example" are used to indicate that they are examples, illustrations, or descriptions. Any embodiment or design that is described as "exemplarily" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or design options. Specifically, the use of the words "exemplarily" or "for example" is intended to present the relevant concepts in a specific manner.

[0148] Seventh, in this application, "send" and "receive" indicate the direction of signal transmission. For example, "send first information to the second communication device" can be understood as the destination of the first information being the second communication device, which may include direct transmission via the air interface or indirect transmission via the air interface by other units or modules. "Receive first information from the first communication device" can be understood as the source of the first information being the first communication device, which may include direct reception from the first communication device via the air interface or indirect reception from the first communication device via the air interface by other units or modules. "Send" can also be understood as the "output" of the chip interface, and "receive" can also be understood as the "input" of the chip interface.

[0149] In other words, sending and receiving can occur between devices, such as between terminal devices and network devices; or they can occur within a device, such as between components, modules, chips, software modules, or hardware modules within a device via a bus, wiring, or interface.

[0150] Eighth, in this application, the solutions in each embodiment can be used in a reasonable combination, and the explanations or descriptions of various terms, similar operations, or steps appearing in the embodiments can be referenced or explained to each other in the various embodiments, without limitation.

[0151] Figure 1 is a schematic diagram of a communication system applicable to an embodiment of this application. The communication system 1000 shown in Figure 1 includes a radio access network (RAN) 100 and a core network (CN) 101. Optionally, the communication system 1000 also includes the Internet 102. The RAN 100 may include at least one RAN node (as shown in Figure 1, 110a and 110b) and at least one terminal (as shown in Figure 1, 120a-120j). The terminal is wirelessly connected to the RAN node, and the RAN node is wirelessly or wiredly connected to the core network 101. The core network equipment and the RAN node can be independent and different physical devices, or the functions of the core network equipment and the logical functions of the RAN node can be integrated on the same physical device, or a single physical device can integrate some of the functions of the core network equipment and some of the functions of the RAN node. Terminals and RAN nodes can be interconnected via wired or wireless means. Figure 1 is only a schematic diagram; the communication system may also include other RAN nodes, such as wireless relay devices and wireless backhaul devices, which are not shown in Figure 1.

[0152] The wireless access network 100 can be a cellular system related to the 3rd generation partnership project (3GPP), such as a 4th generation mobile communication technology (4G) system (also known as a long term evolution (LTE) system), a 5G system (also known as a new radio (NR) system), or it can also be applied to future communication systems or other similar communication systems, etc., which are not limited in this application.

[0153] The wireless access network 100 can also be an open RAN (open-RAN, O-RAN, or ORAN) or a cloud radio access network (CRAN). The wireless access network 100 can also be a non-terrestrial network (NTN), a satellite communication network, a high altitude platform station (HAPS) communication network, an integrated access and backhaul (IAB) communication network, or a reconfigurable intelligent surface (RIS) communication network. The wireless access network 100 can also be a communication system that integrates two or more of the above systems.

[0154] RAN nodes, also known as RAN devices, network devices, or access network devices, are used to help terminal devices achieve wireless access. Multiple RAN nodes in a communication system 1000 can be of the same type or different types.

[0155] In one possible scenario, RAN nodes can be base stations, evolved NodeBs (eNodeBs), access points (APs), transmitting and receiving points (TRPs), transmitting points (TPs), next-generation NodeBs (gNBs), base stations in future mobile communication systems, access points (APs) in satellites, integrated access and backhaul (IAB) nodes, and access network equipment in mobile switching center non-terrestrial network (NTN) communication systems. These can be deployed on high-altitude platforms or satellites. Access network equipment can be macro base stations (as shown in Figure 1, 110a), micro base stations or indoor stations (as shown in Figure 1, 110b), relay nodes or donor nodes, or radio controllers in CRAN scenarios. Access network equipment can also function as base stations in device-to-device (D2D) communication, vehicle-to-everything (V2X) communication, drone communication, and machine-to-machine (M2M) communication. Optionally, access network equipment can also be servers, wearable devices, vehicles, or in-vehicle equipment. For example, the access network equipment in vehicle-to-everything (V2X) technology can be a roadside unit (RSU).

[0156] In another possible scenario, multiple RAN nodes collaborate to assist terminals in achieving wireless access, with different RAN nodes each implementing some of the base station's functions. For example, RAN nodes can be central units (CUs), distributed units (DUs), CU-control plane (CPs), CU-user plane (UPs), or radio units (RUs), etc. CUs and DUs can be set up separately or included in the same network element, such as a baseband unit (BBU). RUs can be included in radio equipment or radio units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs). It is understood that RAN nodes can be CU nodes, DU nodes, or devices that include both CU and DU nodes. Furthermore, a CU can be classified as a RAN node within the RAN, or it can be classified as a core network device within the core network; there are no restrictions on this.

[0157] 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 O-RAN system, CU can also be called O-CU (Open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. 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.

[0158] Terminal equipment is a device with wireless transceiver capabilities, capable of sending signals to or receiving signals from RAN nodes. Terminal equipment can also be referred to as terminal devices, terminals, user equipment (UE), mobile stations, mobile terminals, access terminals, subscriber units, user stations, user terminals, wireless communication equipment, user agents, or user devices, etc. Terminal equipment can be widely used in various scenarios, including but not limited to: enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC), massive machine-type communications (mMTC), device-to-device (D2D), vehicle-to-everything (V2X), machine-type communication (MTC), Internet of Things (IoT), sensing, ISAC, virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, or smart cities, etc. The terminal device can be a mobile phone, tablet computer, computer with wireless transceiver capabilities, wearable device, vehicle, helicopter, airplane, drone, ship, robot, robotic arm, or smart home device, etc. This application does not limit the specific technology or form of the terminal device.

[0159] RAN nodes and terminal devices can be fixed or mobile. They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can be deployed on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of the RAN nodes and terminal devices.

[0160] The roles of RAN nodes and terminal devices can be relative. For example, the helicopter or drone 120i in Figure 1 can be configured as a mobile RAN node. For terminal devices 120j that access the radio access network 100 through 120i, terminal device 120i is a RAN node; however, for RAN node 110a, 120i is a terminal device, meaning that 110a and 120i communicate via a radio interface protocol. Of course, 110a and 120i can also communicate via a RAN node-to-RAN node interface protocol. In this case, relative to 110a, 120i is also a RAN node. Therefore, both RAN nodes and terminal devices can be collectively referred to as communication devices. 110a and 110b in Figure 1 can be called communication devices with RAN node functions, and 120a-120j in Figure 1 can be called communication devices with terminal device functions.

[0161] Communication between RAN nodes and terminal devices, between RAN nodes, and between terminal devices can be conducted using licensed spectrum, unlicensed spectrum, or both simultaneously. Communication can also be conducted using spectrum below 6 gigahertz (GHz), spectrum above 6 GHz, or both simultaneously. The embodiments of this application do not limit the spectrum resources used for wireless communication.

[0162] In the embodiments of this application, the RAN node is also referred to as an access network device. The apparatus for implementing the functions of the access network device can be the access network device itself, or it can be any apparatus capable of supporting the access network device in implementing these functions, such as a chip system, hardware circuit, software module, or a hardware circuit plus a software module. This apparatus can be installed in a network device or used in conjunction with a network device. In this application embodiment, only the network device is used as an example to illustrate the apparatus for implementing the functions of the network device, and this does not constitute a limitation on the solutions of the embodiments of this application. It can also be executed by a control subsystem that includes functions for implementing the network device. This control subsystem that includes functions for implementing the network device can be a control center in the aforementioned application scenarios such as smart grids, industrial control, intelligent transportation, and smart cities.

[0163] In this embodiment, the device for implementing the functions of the terminal device can be the terminal device itself, or any device capable of supporting the terminal device in implementing those functions, such as a chip system, hardware circuit, software module, or a hardware circuit plus a software module. This device can be installed in the terminal device or used in conjunction with the terminal device. In this embodiment, the terminal device is used as an example to illustrate the device for implementing the functions of the terminal device, and this does not constitute a limitation on the solutions described in this embodiment.

[0164] Core network equipment refers to the equipment in the core network that provides service support for terminal equipment. Examples of some core network equipment include: sensing function (SF) network elements, access and mobility management function (AMF) network elements, session management function (SMF) network elements, user plane function (UPF) network elements, etc., which will not be listed here.

[0165] It should be understood that network elements in this application may also be referred to as entities or functional entities. For example, an AMF network element may also be referred to as an AMF entity or an AMF functional entity, and an SMF entity may also be referred to as an SMF network element or an SMF functional entity, etc.

[0166] The names of the network elements shown in this application are merely illustrative examples for ease of description and should not be construed as limiting the scope of this application. This application does not preclude the possibility of defining other terms that can achieve the same or similar functions in existing or future protocols.

[0167] The use of the SF network element as an example in the core network is merely one illustration. In some possible network architectures, the SF network element can also be a network element in the access network, and this application does not limit this. When the SF network element is a network element in the access network, its name may also be different, for example, it may be called a sensing unit (SU). The SU has the same or similar functions as the SF network element.

[0168] SF network elements can be deployed independently in the core network or co-located with other network elements in the core network (e.g., AMF or LMF network elements), depending on requirements. SF network elements can implement basic sensing functions, such as sensing authorization, sensing capability interaction, network element selection, sensing control, sensing data processing, and result output. SF network elements interact with AMF and other network elements through interfaces. Sensing control signaling between SF network elements and the RAN or terminals is transmitted through AMF network elements, and sensing data acquired by the RAN or terminals can be transmitted to SF network elements via the control plane or user plane.

[0169] In this application, the terminal device and the network device are connected via an air interface. In LTE / Long Term Evolution Advanced (LTE-A) and NR systems, duplex modes can be mainly divided into Frequency Division Duplex (FDD) and Time Division Duplex (TDD). For wireless communication systems operating in TDD mode, the downlink and uplink carriers share the same carrier frequency. Multiple access methods typically employ Orthogonal Frequency Division Multiple Access (OFDMA). The main characteristic of OFDMA is that it divides transmission resources into mutually orthogonal time-frequency resource elements (REs). Signals transmitted by the transmitter are carried on REs and transmitted to the receiver. Because different REs are orthogonal, the receiver can receive the signals transmitted on each RE individually.

[0170] The relevant technologies and concepts involved in this application are introduced below.

[0171] Sensing signal: A signal transmitted over the air interface that can be used for sensing; it can also be called a sensing reference signal. Sensing services can be implemented by processing the sensing signal.

[0172] Sensing transmitter: A network device or terminal device that sends sensing signals. The sensing transmitter can be located in the same network device or terminal device as the sensing receiver; or it can be located in a different network device or terminal device.

[0173] Sensing receiver: A network device or terminal device that receives sensing signals. The sensing receiver can be located in the same network device or terminal device as the sensing transmitter; alternatively, it can be located in a different network device or terminal device.

[0174] Sensing target: also known as the perceived target, target, etc. The characteristics of the target are derived based on the sensed signals.

[0175] Mono-static sensing: The sensing transmitter that sends the sensing signal and the sensing receiver that receives the sensing signal are located in the same network device or terminal device. Mono-static sensing can also be called single-site sensing. In the transmission process of the sensing signal, a sensing device (or sensing site) must both send the sensing signal and receive the signal reflected from the target surface (also known as the echo signal). Therefore, single-site sensing is also called a self-transmitting and self-receiving mode.

[0176] Bi-static sensing: The sensing transmitter that sends the sensing signal and the sensing receiver that receives the sensing signal are not in the same network device or terminal device. Bi-static sensing can also be called dual-site sensing. In the transmission process of the sensing signal, after sensing device A sends the sensing signal, the signal reflected from the target surface is received by sensing device B. Therefore, dual-site sensing mode is also called A-transmit B-receive mode.

[0177] In the vision of enhancing and expanding 5G scenarios, in addition to continuing to strengthen the three standard scenarios of enhanced mobile broadband (eMBB), massive machine type of communication (mMTC), and ultra-reliable low latency communications (URLLC), three new scenarios will also be expanded, including uplink centric broadband communication (UCBC), real-time broadband communication (RTBC), and integrated sensing and communication (ISAC). Integrated sensing and communication can also be called harmonized communication and sensing (HCS), or simply sensing fusion.

[0178] 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 the ability to detect, track, and image targets. This allows communication and sensing capabilities to be integrated into a single network, achieving harmonious coexistence and even mutual benefit. The target can also be referred to as the sensing target or the perceived target.

[0179] Figure 2 is a schematic diagram of a sensor fusion scenario. Network devices can communicate with and sense terminal devices; similarly, terminal devices can communicate with and sense network devices. A terminal device can be a sensing receiver or a sensing transmitter, and a network device can be both a sensing receiver and a sensing transmitter. Furthermore, a terminal device can communicate with and sense another terminal device.

[0180] The technical principles of sensing and communication differ to some extent. In communication, the transmitting end modulates information onto radio waves and sends it to the receiving end, which then demodulates the signal to obtain the information. Sensing, however, requires the transmitting end to send radio waves in a specific direction (i.e., send a sensing signal). When the radio waves reach the target surface, they form reflected waves (i.e., echo signals). The receiving end receives and processes these reflected waves, or in other words, senses the target based on them to obtain information such as its position, speed, and type. The echo signal is the signal generated by the sensing signal reflecting off the target in the environment. The time delay of the echo signal relative to the transmitted sensing signal reflects the target's distance, and the Doppler shift of the echo signal relative to the transmitted sensing signal reflects the target's speed.

[0181] Applications of sensor fusion include, but are not limited to: smart homes, smart factories, rail networks, emergency networks, vehicle-to-everything (V2X) networks, and drones. By applying massively multi-input multiple-output (MIMO) beam scanning technology to the perception field, sensor fusion enables both communication and perception capabilities, thus supporting the development of autonomous driving. Extending to indoor scenarios, sensor fusion can also provide positioning services.

[0182] In existing beam management mechanisms, network devices use different beams to transmit reference signals (such as the sensing signals described above, or existing communication reference signals, such as synchronization signal blocks (SSBs) and channel state information reference signals (CSI-RS)) on different resources. Terminal devices measure the reference signals on different beams and report the measurement results to the network devices. These measurement results are used by the network devices to determine the optimal beam for subsequent transmissions.

[0183] For communication services, ensuring the link quality between network devices and terminal devices is crucial. Terminal devices typically measure reference signals, including RSRP and signal-to-interference-plus-noise ratio (SINR). For example, a terminal device might select the top X beams with the highest RSRP and report them to the network device. Figure 3 illustrates beam scanning. As shown in Figure 3, when the network device and terminal device are in a strong line-of-sight (LOS) environment, the RSRP value measured under an LOS beam (e.g., beam 1 in Figure 3) is higher than the RSRP value measured under typical non-line-of-sight (NLOS) beams (e.g., beams 2, 3, or 4 in Figure 3). Therefore, the terminal device can report beam 1 to the network device.

[0184] For sensing services, ensuring link quality between network devices, targets, and terminal devices is crucial. To identify the beam containing the target, in one possible implementation, the terminal device can determine the beam to report based on the received power within a delay range and / or a Doppler range. For example, when sensing a moving target, the terminal device can calculate the received power of different beams within a Doppler range greater than 0, and then select the top X beams with the highest received power measured within that Doppler spectrum range to report to the network device. Based on the scenario shown in Figure 3, where a target (a person is shown in Figure 3) exists in the environment, Figure 4 shows the Doppler spectra obtained by the terminal device on beams 2, 3, and 4. Within the Doppler range greater than 0, the received power measured on beam 2 is the highest. The terminal device can report beam 2 to the network device. In fact, beam 2 is the beam containing the target, which can be considered the target's main lobe beam. Beams 3 and 4 are beams adjacent to beam 2, and can also be considered as the target's sidelobe beams.

[0185] Figures 3 and 4 illustrate this using a single target as an example. However, in a real environment, multiple targets may exist, and these targets may be located on different beams. Since the distances between different targets and network or terminal devices may vary, the path loss may also differ. For example, the farther the target is from the network or terminal device, the greater the path loss; conversely, the closer the target is, the smaller the path loss. This can lead to differences in the received power measured on different beams where the target is present. In some scenarios, the presence of a strong target may result in higher received power measured on multiple adjacent beams, or even greater received power measured on the sidelobe beam of a strong target than on the main lobe beam of a weak target.

[0186] For example, as shown in Figure 5, a schematic diagram of beam scanning illustrates two targets in the environment: a person and a vehicle. The person is located on beam 2, and the vehicle is located on beam 4. The person is closer to the network and terminal devices, resulting in less path loss, while the vehicle is farther away, leading to greater path loss. Therefore, the path loss for the person is less than that for the vehicle, and the person can be considered a strong target, while the vehicle can be considered a weak target. Based on the scenario of two targets in the environment shown in Figure 5, Figure 6 shows the Doppler spectra obtained by the terminal device on beams 2, 3, and 4. Within the range where Doppler is greater than 0, the highest received reference signal power is measured on beam 2 (approximately -43 dB), followed by beam 3 (approximately -51 dB), and the lowest is measured on beam 4 (approximately -57 dB).

[0187] It should be understood that the received power measured on a certain beam as described herein refers to the total received power within a Doppler range measured on that beam.

[0188] It should also be understood that Figure 6 is illustrated using Doppler spectra obtained on different beams as examples. These Doppler spectra can also be replaced by time-delay spectra or time-delay-Doppler spectra, and the embodiments of this application do not limit this.

[0189] As shown in Figures 5 and 6, because the road loss for humans is less than that for vehicles, the received power measured on beam 2 is greater than that measured on beam 4. However, the received power measured on beam 3 is also greater than that measured on beam 4. In reality, there is no target on beam 3; the received power measured on beam 3 mainly comes from leakage from beam 2. In this situation, if the terminal device still reports the valid beams to the network device based on the received power measured on different beams—for example, reporting the top X beams with the highest received power—the network device may be unable to accurately identify the beam where the target is located.

[0190] For example, if the terminal device reports the highest received power of the first beam (i.e., reported beam 2) or the first two beams (i.e., reported beams 2 and 3), then beam 4 will not be able to be reported, which will cause the network device to fail to detect the vehicle as a weak target.

[0191] For example, if the terminal device reports the three beams with the highest received power (i.e., reporting beams 2, 3, and 4), since the received power measured on beam 3 is greater than that measured on beam 4, beam 3 has a higher priority than beam 4. The network device may mistakenly believe that there is a target on beam 3, thus causing a false alarm. Subsequently, the network device may prioritize configuring sensing resources for beam 3, which will lead to a waste of sensing resources.

[0192] In view of this, embodiments of this application provide a measurement and reporting method. In this method, the terminal device can measure the reference signal received path power of different paths on multiple beams and report at least one beam with the highest reference signal received path power for each path. This path-based reporting method is beneficial for network devices to more accurately identify the beam where the target is located in multi-target scenarios.

[0193] The technical solution of this application involves measurement reporting between two sensing devices, which belongs to dual-site sensing. For example, this application can be applied to scenarios where sensing occurs between network devices and terminal devices in a cellular network, or it can also be applied to scenarios where sensing occurs between multiple terminal devices.

[0194] Figure 7 is a schematic flowchart of a measurement reporting method 700 provided in an embodiment of this application. In method 700, the communication device (such as a first communication device and a second communication device) can be a communication equipment or a module (e.g., a processor, chip, chip system, circuit, etc.) configured in a communication equipment. The first communication device and the second communication device are different communication devices.

[0195] It should be noted that the communication device in this application has both sensing and communication functions, or in other words, it can realize both communication and sensing functions.

[0196] For example, the first communication device may be a terminal device or a module configured in a terminal device, and the second communication device may be a network device or a module configured in a network device.

[0197] For example, the first communication device may be a terminal device or a module configured in the terminal device, and the second communication device may be a terminal device or a module configured in the terminal device.

[0198] Method 700 includes, but is not limited to, S701 and S702. The steps are described in detail below.

[0199] S701, the second communication device sends reference signals on multiple beams to the first communication device. Correspondingly, the first communication device receives the reference signals on the multiple beams.

[0200] In this step, the second communication device can transmit beams in different directions on different time-frequency resources. Each beam carries a reference signal, and the reference signal carried on each beam is used to sense targets in the direction of that beam. The sensing results may include one or more of the following: whether there is a target in the direction of that beam, the target's motion information, the target's motion change information, the target's distance information, the target's velocity information, or the target's angle information.

[0201] Optionally, the time and frequency resources where different beams are located can be pre-configured; or, the second communication device can configure or indicate to the first communication device in advance; or, the second communication device can receive configuration information or indication information from network elements of the auxiliary sensing function in the core network to configure or indicate the time and frequency resources where different beams are located.

[0202] It should be understood that the time-frequency resources of different beams can be understood as the time-frequency resources of the reference signals carried on different beams.

[0203] It should be understood that the reference signal can also be described as a sensed reference signal, or a sensed signal.

[0204] S702, the first communication device sends first information to the second communication device. The first information indicates at least one beam corresponding to each of the at least one path, wherein the at least one beam corresponding to each path is the at least one beam with the highest reference signal receiving power on each of the plurality of beams. Accordingly, the second communication device receives the first information.

[0205] Here, "at least one path" refers to at least one propagation path of the reference signal on the plurality of beams in the environment. When mapped to the time delay domain or Doppler domain, different paths correspond to different time delay positions or Doppler positions, or in other words, different paths are at different time delay positions or Doppler positions. When measuring the reference signal on a beam in the Doppler domain, the Doppler position where the power peak occurs can be regarded as the Doppler position corresponding to a path. That is, a path is represented by a power peak in the Doppler domain, and the physical meaning of this power peak is a propagation path.

[0206] Before the first communication device sends the first information to the second communication device, the first communication device measures the reference signal receiving path power for each beam at different time delay and / or Doppler positions. For example, the first communication device obtains the Doppler spectrum, time delay spectrum, or time delay-Doppler spectrum based on the received reference signal on the first beam and the local sequence.

[0207] It should be understood that the Doppler spectrum shows the power distribution of each Doppler component of the received signal. The time-delay spectrum shows the power distribution of each time-delay component of the received signal. The time-delay-Doppler spectrum can be viewed as a combination of the Doppler spectrum and the time-delay spectrum, showing the power distribution of the received signal at the combination points of each time-delay component and Doppler component.

[0208] Optionally, the plurality of beams includes a first beam, and at least one path includes a first path. The reference signal receiving path power of each path on the plurality of beams includes: the reference signal receiving path power of the first path on the first beam. Wherein, the first beam is any one of the plurality of beams, and the first path is any one of the at least one path.

[0209] Optionally, the reference signal receiving power of the first path on the first beam can be any of the following: the received power of the reference signal on the first beam at the time delay-Doppler position of the first path; or, the received power of the reference signal on the first beam at the Doppler position of the first path; or, the received power of the reference signal on the first beam at the Doppler position of the first path.

[0210] The following description uses the measurement of reference signals on multiple beams in the Doppler domain to obtain the Doppler spectra of these multiple beams as an example.

[0211] Taking the Doppler spectrum measured on beam 2 as an example, as shown in Figure 6, a significant power peak can be observed at the Doppler position around 90Hz. This suggests that when measuring the reference signal on beam 2 in the Doppler domain, the received power at the Doppler position around 90Hz is relatively high, while the received power at other Doppler positions is relatively low and can be ignored. Alternatively, this can be understood as detecting a path with a Doppler frequency of approximately 90Hz on beam 2, meaning the Doppler position of this path is 90Hz. Similarly, it can be assumed that a path with a Doppler frequency of approximately 90Hz is detected on beam 3, and the Doppler position of this path is 90Hz. Furthermore, a path with a Doppler frequency of approximately 365Hz is also detected on beam 4, meaning the Doppler position of this path is 365Hz.

[0212] It should be understood that measuring a reference signal on a certain beam in the Doppler domain, time-delay domain, or time-delay-Doppler domain can also be understood as converting the reference signal on that beam to the Doppler domain, time-delay domain, or time-delay-Doppler domain.

[0213] It should also be understood that power peaks detected by different beams at the same time delay position and / or Doppler position can be considered as the same path. For example, in Figure 6, the power peaks detected by beams 2, 3, and 4 at a Doppler position of around 90Hz can be considered as the same path, referred to as path 1 below. The Doppler position of path 1 is 90Hz. The path detected by beam 4 at a Doppler position of around 365Hz below will be referred to as path 2 below. The Doppler position of path 2 is 365Hz.

[0214] Furthermore, since interference may vary in different beam directions, the Doppler position and / or time delay position of the detected power peak may deviate for the same target in the environment on different beams. Therefore, power peaks whose time delay position and / or Doppler position difference is less than the deviation threshold can be regarded as the same path.

[0215] For example, if a path with a Doppler frequency of 90 Hz is detected on beam 2 and a path with a Doppler frequency of 91 Hz is detected on beam 3, and the deviation threshold is 1 Hz, then the first communication device can regard these two paths as one path.

[0216] Optionally, the first communication device may determine at least one beam corresponding to each path based on the power of the reference signal received path on multiple beams for each path. For example, the first X beams with the highest power of the reference signal received path on multiple beams for each path may be reported to the second communication device, that is, at least one beam corresponding to each path is the first X beams with the highest power of the reference signal received path on multiple beams for each path.

[0217] The following example illustrates how the first communication device reports at least one beam corresponding to each path, taking the at least one path including the aforementioned path 1 and path 2, and the plurality of beams including the aforementioned beam 2, beam 3, and beam 4 as an example.

[0218] For path 1, its reference signal reception power on beams 2, 3, and 4 is -52dB, -60dB, and -68dB, respectively. That is, path 1 has the highest reference signal reception power on beam 2, followed by beam 3, and the lowest on beam 4. For path 2, its reference signal reception power on beam 4 is -73dB.

[0219] If X = 1, then for path 1, the first communication device can report beam 2, meaning that at least one beam corresponding to path 1 includes beam 2; for path 2, the first communication device can report beam 4, meaning that at least one beam corresponding to path 2 includes beam 4. In this case, the first communication device does not report beam 3 (because there is no target on beam 3), but instead reports beams 2 and 4 (because there are targets on beams 2 and 4; beam 2 shows a strong target, and beam 4 shows a weak target). This helps avoid situations where weak target detection fails or non-target beams are reported. Here, a non-target beam refers to a beam where no target exists.

[0220] If X = 2, then for path 1, the first communication device can report beams 2 and 3, meaning that at least one beam corresponding to path 1 includes beams 2 and 3; for path 2, the first communication device can report beam 4, meaning that at least one beam corresponding to path 2 includes beam 4. In this case, even if the first communication device reports beams 2, 3, and 4 to the second communication device, since beams 3 and 4 correspond to different paths, there is no situation where beam 3 has a higher priority than beam 4. After receiving the first information, the second communication device can determine that path 1 corresponds to beams 2 and 3, and path 2 corresponds to beam 4. That is, the two beams with the highest reference signal reception power for path 1 across multiple beams include beams 2 and 3, and the two beams with the highest reference signal reception power for path 2 across multiple beams include beam 4.

[0221] It should be understood that there is a hierarchy of priority among at least one beam corresponding to the same path in this application, while there is no hierarchy of priority among multiple beams corresponding to different paths. For example, there is a hierarchy of priority between beams 2 and 3 corresponding to path 1, but there is no hierarchy of priority between beam 3 of path 1 and beam 4 of path 2.

[0222] It should also be understood that if the reference signal receiving power of a path on its corresponding beam is higher, then the beam ranks higher or has a higher priority among at least one beam corresponding to that path; conversely, if the reference signal receiving power of a path on its corresponding beam is lower, then the beam ranks lower or has a lower priority among at least one beam corresponding to that path. For example, for path 1, since the reference signal receiving power of path 1 on beam 2 is higher than that of path 1 on beam 3, then beam 2 has a higher priority than beam 3.

[0223] For the second communication device, if the number of at least one beams corresponding to a certain path reported by the first communication device is greater than or equal to 2, the second communication device needs to determine the priority among the at least one beams corresponding to that path. The beam with the highest priority among the at least one beams corresponding to that path (i.e., the one with the highest power of the reference signal receiving path on that beam) is highly likely to contain a target; that is, the highest priority beam is the target's main beam. Other beams with lower priority among the at least one beams corresponding to that path may be the target's sidelobe beams. In this way, the second communication device can allocate sensing resources for the highest priority beam.

[0224] The following describes how the second communication device determines the priority of at least one beam corresponding to a certain path when the number of at least one beam corresponding to a certain path reported by the first communication device is greater than or equal to 2.

[0225] In one implementation, the first communication device can report at least one beam corresponding to each path based on a predefined reporting method (or reporting format) of the protocol. The predefined reporting method (or reporting format) can implicitly indicate the sorting information or priority information of the at least one beam corresponding to each path. In this way, the second communication device can determine the sorting information or priority information of the at least one beam corresponding to each path based on the reporting method (or reporting format) of the first communication device for the first information.

[0226] In another implementation, the first communication device can indicate the ordering or priority information of at least one beam corresponding to each path through first information. For example, the higher the power of the reference signal receiving path of a beam, the higher its order or priority; the lower the power of the reference signal receiving path of a beam, the lower its order or priority. For example, it can be indicated that the order of beam 2 corresponding to path 1 is 1, and the order of beam 3 corresponding to path 1 is 2, with beam 2 being ordered earlier and beam 3 being ordered later.

[0227] Optionally, in order for the second communication device to more accurately determine the main lobe beam of the target, the first communication device may also indicate to the second communication device one or more of the following through the first information: the reference signal received path power of each path in each of the corresponding at least one beam, the time delay-Doppler position of each path, the Doppler position of each path, or the time delay position of each path.

[0228] For example, the first communication device reports that the reference signal received path power of beam 2 corresponding to path 1 is -52dB, the reference signal received path power of beam 3 corresponding to path 1 is -60dB, and the Doppler position of path 1 is 90Hz. The first communication device also reports that the reference signal received path power of beam 3 corresponding to path 2 is -68dB, and the Doppler position of path 2 is 365Hz.

[0229] Optionally, the first information includes an identifier for each beam in at least one beam corresponding to each path. That is, the first communication device indicates each beam in at least one beam corresponding to each path using the identifier for each beam in at least one beam corresponding to each path, wherein different beams have different identifiers, i.e., different identifiers can distinguish different beams. Alternatively, the first information includes an identifier for a reference signal on each beam in at least one beam corresponding to each path. That is, the first communication device indicates each beam in at least one beam corresponding to each path using the identifier for the reference signal on each beam in at least one beam corresponding to each path. Here, one reference signal is carried on one beam, and the beam carrying the reference signal can be indicated by the identifier of the reference signal.

[0230] In the above method 700, the first communication device measures the reference signal received path power of multiple beams in the time delay domain, Doppler domain, or time delay-Doppler domain, and reports that each path corresponds to at least one beam, that is, the top X beams with the highest reference signal received path power. This reporting method with path as the granularity is beneficial for the second communication device to more accurately identify the beam where the target is located in a multi-target scenario.

[0231] Optionally, the first communication device can independently determine the number of at least one path in S702 (i.e., the number of paths to be reported), and / or the number of at least one beam corresponding to each path in S702 (i.e., the number of beams to be reported for each path). Alternatively, the first communication device can receive second information from the second communication device, the second information indicating the number of at least one path in S702, and / or the number of at least one beam corresponding to each path in S702. Or, the first communication device can receive second information from a network element (e.g., an SF network element) responsible for sensing functions in the core network, the second information indicating the number of at least one path in S702, and / or the number of at least one beam corresponding to each path in S702. The number of beams to be reported for different paths can be the same or different.

[0232] It should be noted that Figure 6 above only shows the Doppler spectrum obtained from measurements on three beams. In reality, more beams can exist; for example, the second communication device uses a total of 64 beams for beam scanning. For each path, the reference signal receiving path power on all beams can be sorted, and the top X beams with the highest reference signal receiving path power for each path can be determined in descending order. Alternatively, the reference signal receiving path power greater than the threshold corresponding to each path can be sorted, and the top X beams with the highest reference signal receiving path power for each path can be determined in descending order. This helps reduce the power consumption of the first communication device. The top X beams with the highest reference signal receiving path power for each path are at least one beam corresponding to each path. In other words, in this application, the reference signal receiving power on each of the at least one beam corresponding to each path is greater than the threshold corresponding to each path.

[0233] For example, for path 1, the reference signal received path power on beams 2, 3, and 4 is greater than the threshold corresponding to path 1. For path 2, the reference signal received path power on beam 4 is greater than the threshold corresponding to path 2, while the reference signal received path power of path 2 on other beams (e.g., beam 2 or beam 3) is less than the threshold corresponding to path 2, or path 2 is not detected on other beams. Therefore, when X = 2, only beam 4 can report path 2, and other beams do not meet the reporting conditions.

[0234] Optionally, different paths can share the same threshold. Furthermore, since the path loss increases with distance from the target to the first or second communication device, the power of the reference signal receiving path on the beam containing the target is lower, and the time delay is greater with distance from the target to the first or second communication device. Therefore, different thresholds can be configured for paths at different time delay positions; that is, different paths can have different thresholds, which can be partially or completely different. The threshold for each path is related to its time delay position. For example, the greater the time delay, the smaller the threshold for the path at that time delay position; conversely, the smaller the time delay, the larger the threshold for the path at that time delay position.

[0235] In one implementation, a desired latency range can be further divided into multiple latency sub-ranges, each latency sub-range corresponding to a threshold. Multiple paths within the same latency sub-range correspond to the same threshold, while multiple paths within different latency sub-ranges correspond to different thresholds.

[0236] Optionally, the first communication device can determine the threshold corresponding to each path independently. Alternatively, the first communication device receives third information from the second communication device, which indicates the threshold corresponding to each path, and the first communication device determines the threshold corresponding to each path based on the indication from the second communication device. Or, the first communication device receives third information from a network element in the core network responsible for sensing functions, which indicates the threshold corresponding to each path, and the first communication device determines the threshold corresponding to each path based on the indication from the network element in the core network responsible for sensing functions.

[0237] Optionally, the first communication device may report at least one beam corresponding to each of at least one path within the first Doppler range and / or the first time delay range. That is, the Doppler position of each path in the at least one path in S702 above belongs to the first Doppler range, and / or the time delay position of each path in the at least one path in S702 above belongs to the first time delay range. Here, the first Doppler range and / or the first time delay range are the desired Doppler range and / or time delay range to be measured, or the expected time delay and / or Doppler of the target by the sensing service. In this way, when performing sensing, the first communication device only needs to focus on the target within the first Doppler range and / or the first time delay range, which helps reduce the computational load of the first communication device and lower power consumption.

[0238] Optionally, the first communication device may independently determine the first Doppler range and / or the first time delay range. Alternatively, the first communication device may receive fourth information from the second communication device, the fourth information indicating the first Doppler range and / or the first time delay range. Or, the first communication device may receive fourth information from a network element in the core network responsible for sensing functions, the fourth information indicating the first Doppler range and / or the first time delay range.

[0239] To enable the second communication device to more accurately determine the beam containing the target, the first information may optionally also indicate the similarity between the power spectrum of the second beam and the power spectrum of the third beam. It should be understood that using similarity as an indicator for determining the beam containing the target is primarily to identify whether a beam with higher power on a reference signal receiving path along a path is a sidelobe beam of a strong target or a main lobe beam of a weak target. After receiving the first information, the second communication device combines the similarity between the power spectrum of the second beam and the power spectrum of the third beam to determine whether the second beam is a sidelobe beam of a strong target or a main lobe beam of a weak target, thereby determining the beam containing the target. Here, the second beam is any one of at least one beams corresponding to each path, and the third beam includes beams in at least one beam corresponding to each path whose reference signal receiving path power is higher than that of the second beam.

[0240] The power spectrum of the second beam can be a time-delay-Doppler-power spectrum, or a Doppler-power spectrum, or a time-delay-power spectrum obtained from the reference signal received on the second beam.

[0241] In this embodiment, the similarity between the power spectra of two beams can be the cosine similarity, Euclidean distance, Manhattan distance, etc., between the power spectrum vectors of the two beams. The similarity value ranges from [0,1].

[0242] Taking the cosine similarity between the power spectral vectors of beam 2 and beam 3 as an example, assuming the power spectral vector of beam 2 is a = [a1, a2, ..., a...] N The power spectral vector of beam 3 is b = [b1, b2, ..., b]. N The similarity between the two satisfies the following formula:

[0243] Where N represents the number of Doppler components in the Doppler spectrum / the number of time delay components in the time delay spectrum / the number of time delay-Doppler components in the time delay-Doppler spectrum, and a i b represents the amplitude of the reference signal received on beam 2 at the i-th time-delay-Doppler component / i-th Doppler component / i-th time-delay component in the time-delay-Doppler spectrum. iThis represents the amplitude of the reference signal received on beam 3 in the time-delay-Doppler spectrum at the i-th time-delay-Doppler component / i-th Doppler component / i-th time-delay component.

[0244] Taking at least one beam corresponding to path 1, including beams 2, 3, and 4, as an example, the reference signal received power of path 1 on beam 2 is the highest, the reference signal received power of path 1 on beam 3 is the second highest, and the reference signal received power of path 1 on beam 4 is the lowest. When calculating the similarity between the power spectrum of each beam in the at least one beam corresponding to path 1 and the power spectrum of the beam with the highest reference signal received power, since the reference signal received power of path 1 on beam 2 is the highest, and there is no beam in the at least one beam corresponding to path 1 with a higher reference signal received power than path 1 on beam 2, the first communication device can report a similarity of 0 for beam 2, or not report a similarity of beam 2, meaning that the reference signal received power of path 1 on beam 2 is the highest. For beam 3, since the reference signal received power of path 1 on beam 2 is higher than the reference signal received power of path 1 on beam 3, therefore, the first communication device... A communication device can report to a second communication device the similarity between the power spectrum of beam 3 and the power spectrum of beam 2 (hereinafter referred to as similarity 3-2); for beam 4, since the reference signal received path power of path 1 on beam 2 is higher than that of path 1 on beam 4, and the reference signal received path power of path 1 on beam 3 is higher than that of path 1 on beam 4, the first communication device can report to the second communication device the similarity between the power spectrum of beam 4 and the power spectrum of beam 2 (hereinafter referred to as similarity 4-2), and the similarity between the power spectrum of beam 4 and the power spectrum of beam 3 (hereinafter referred to as similarity 4-3).

[0245] After receiving the first information, the second communication device can determine that beam 2, corresponding to path 1, is the beam containing a target. For beam 3, corresponding to path 1, the second communication device compares the similarity 3-2 with a first threshold. If the similarity 3-2 is greater than the first threshold, it means that beam 3 may be a sidelobe beam of a strong target. If the similarity 3-2 is less than the first threshold, it means that there may be a new target on beam 3. For beam 4, corresponding to path 1, the second communication device compares the similarity 4-2 with the first threshold. If the similarity 4-2 is greater than the first threshold, it means that beam 4 may be a sidelobe beam of a strong target. If the similarity 4-2 is less than the first threshold, it means that there may be a new target on beam 4. It should be noted that if the similarity 3-2 is less than the first threshold, the second communication device can further compare the similarity 4-3 with the first threshold. If the similarity 4-3 is greater than the first threshold, it means that beam 4 may be a sidelobe beam of a strong target on beam 3. If the similarity 4-3 is less than the first threshold, it means that there may be a new target on beam 4. If the similarity 3-2 is greater than the first threshold, the second communication device may not compare the similarity 4-3 with the first threshold, but only compare the similarity 4-2 with the first threshold.

[0246] It should be understood that, generally, higher sidelobe power is more likely to be measured on an adjacent beam of a beam with a target. Therefore, the first communication device may simply calculate or report the similarity between the power spectrum of a beam and the power spectrum of a beam that has a higher power than its reference signal receiving path and is adjacent to it.

[0247] Taking at least one beam corresponding to the aforementioned path 1, including beams 2, 3, and 4, as an example, the reference signal received power of path 1 on beam 2 is the highest, the reference signal received power of path 1 on beam 3 is the second highest, and the reference signal received power of path 1 on beam 4 is the lowest. If beam 2 is not an adjacent beam of beam 3, the first communication device may not calculate the similarity between the power spectrum of beam 3 and the power spectrum of beam 2, or in other words, may not consider the similarity index to determine whether to report beam 3; if beam 3 is an adjacent beam of beam 4, and beam 2 is not an adjacent beam of beam 4, the first communication device may only calculate the similarity between the power spectrum of beam 4 and the power spectrum of beam 3, and not calculate the similarity between the power spectrum of beam 4 and the power spectrum of beam 2.

[0248] Optionally, the first communication device can independently determine the adjacent beams of each of the plurality of beams. Alternatively, the first communication device can receive fifth information from the second communication device, the fifth information being used to indicate the adjacent beams of each of the plurality of beams. Alternatively, the first communication device can receive fifth information from a network element in the core network responsible for sensing functions, the fifth information being used to indicate the adjacent beams of each of the plurality of beams.

[0249] For example, the fifth piece of information includes the time-frequency resources of each beam's adjacent beams. The first communication device can determine the adjacent beams of each beam through the time-frequency resources of each beam. Alternatively, the protocol predefines or the first and second communication devices have pre-negotiated the relationship between the time-frequency resources of adjacent beams, for example, the time-frequency resources of adjacent beams are also adjacent.

[0250] It should be noted that the two beams are adjacent beams, which can be understood as the two beams being adjacent in direction or angle.

[0251] In the embodiment described in the above-described method 700, the first communication device measures the reference signal receiving path power in the time delay domain and / or Doppler domain, and for at least one path detected in the time delay domain and / or Doppler domain, the first communication device reports at least one beam corresponding to each path, i.e., the top X beams with the highest reference signal receiving path power for each path across multiple beams.

[0252] As described above regarding similarity, similarity can be used to determine whether a beam is a sidelobe beam of a strong target or a main lobe beam of a weak target. Based on this, this application also provides a measurement reporting method. In this method, the first communication device does not need to report by path, but instead determines the beam to be reported by combining the similarity between the power spectrum of each beam and the power spectrum of other beams. See the descriptions of methods 800 and 900 below for details.

[0253] Figure 8 is a schematic flowchart of a measurement reporting method 800 provided in an embodiment of this application. In method 800, the communication device (such as a first communication device and a second communication device) can be a communication equipment or a module (e.g., a processor, chip, chip system, circuit, etc.) configured in a communication equipment. The first communication device and the second communication device are different communication devices.

[0254] For example, the first communication device may be a terminal device or a module configured in a terminal device, and the second communication device may be a network device or a module configured in a network device.

[0255] For example, the first communication device may be a terminal device or a module configured in the terminal device, and the second communication device may be a terminal device or a module configured in the terminal device.

[0256] Method 800 includes, but is not limited to, S801 and S802. The steps are described in detail below.

[0257] S801, the second communication device sends reference signals on multiple beams to the first communication device. Correspondingly, the first communication device receives the reference signals on the multiple beams.

[0258] For an explanation of this step, please refer to the description of S701 above; it will not be repeated here.

[0259] S802, the first communication device sends sixth information to the second communication device, the sixth information indicating at least one beam among the plurality of beams. Correspondingly, the second communication device receives the sixth information. Wherein, the similarity between the power spectrum of the fourth beam and the power spectrum of the fifth beam among the at least one beam is less than a first threshold, the fourth beam is any one of the at least one beams, and the fifth beam is the beam among the plurality of beams with a higher reference signal received power than the fourth beam.

[0260] In one implementation, the sixth information may include the identifier of each beam in the at least one beam, with different beams corresponding to different identifiers, that is, the first communication device can indicate the beam by the identifier of the beam.

[0261] In another implementation, the sixth information may include an identifier of a reference signal on each of the at least one beam, with one reference signal carried on each beam and one identifier corresponding to each reference signal. That is, the first communication device can obtain the identifier of the reference signal on the beam from the indicating beam.

[0262] The similarity between the power spectra of the two beams will be described in detail below.

[0263] It should be understood that the power spectrum of a beam can be a time-delay-Doppler-power spectrum, or a Doppler-power spectrum, or a time-delay-power spectrum, based on a reference signal received on that beam.

[0264] The similarity between the power spectra of two beams in this embodiment can be the cosine similarity, Euclidean distance, Manhattan distance, etc., between the power spectrum vectors of the two beams. The similarity value ranges from [0,1]. The formula for calculating the similarity is as shown above and will not be repeated here.

[0265] In the embodiments of this application, the first communication device can determine at least one beam to be reported based on the reference signal received power and similarity of each of the plurality of beams. Two implementation methods for determining the at least one beam are described below.

[0266] In one implementation method, the first communication device sorts the multiple beams according to their reference signal received power, determining the top X beams with the highest reference signal received power. For each of these top X beams, the first communication device calculates the similarity between the power spectrum of each beam and the power spectrum of a beam with a higher reference signal received power, and compares this similarity with a first threshold. If the similarity is less than the first threshold, the beam can be reported; if the similarity is greater than the first threshold, the beam is not reported. In other words, the at least one beam indicated by the sixth information includes at least one of the top X beams with the highest reference signal received power. The first threshold is a decimal between 0 and 1.

[0267] For example, the first threshold is 0.95, and the multiple beams include beam 1, beam 2, beam 3, beam 4, beam 5, and beam 6. Among them, the X beams with the highest reference signal received power include beam 2, beam 3, and beam 4. For example, as shown in Figure 6, the reference signal received power of beam 2 is higher than that of beam 3, and the reference signal received power of beam 3 is higher than that of beam 4. For beam 2, since it has the highest reference signal received power among beams 2, 3, and 4, and there are no beams with higher reference signal received power, there is a high probability that a target exists on beam 2. Therefore, the first communication device can report beam 2. This can be understood as the similarity between the power spectrum of beam 2 and the power spectrum of the beam with higher reference signal received power is 0, which is less than the first threshold, or beam 2 is the beam with the highest reference signal received power, and the reported beams include at least beam 2. For beam 3, since the reference signal received power of beam 2 is greater than that of beam 3, the first communication device calculates the similarity between the power spectrum of beam 3 and the power spectrum of beam 2. If the similarity is 1, which is greater than the threshold, the first communication device will report the similarity. Since beam 3 can be considered a sidelobe beam of a strong target on beam 2, the first communication device may not report beam 3, which has a lower reference signal received power, given that beam 2 has already been reported. For beam 4, although the reference signal received power of beam 2 is greater than that of beam 4, and the reference signal received power of beam 3 is greater than that of beam 4, the first communication device may not calculate the similarity between the power spectrum of beam 4 and the power spectrum of beam 3, but only the similarity between the power spectrum of beam 4 and the power spectrum of beam 2, since beam 3 is not reported. If the similarity is 0.89, which is less than the first threshold, the first communication device may report beam 4. Thus, even if the reference signal received power of beam 3 is higher than that of beam 4, the first communication device will not report beam 3 because the similarity between the power spectrum of beam 3 and the power spectrum of beam 2 is greater than the first threshold. For example, as shown in Figure 5, there is no target on beam 3, and beam 3 is a sidelobe beam of a strong target on beam 2. There is a weak target on beam 4. This can help to more accurately identify the beam where the target is located and avoid reporting non-target beams.

[0268] In the second implementation method, the first communication device sorts the multiple beams according to the power of the reference signal received. For each beam, it calculates the similarity between the power spectrum of the beam and the beam with a higher power of the reference signal received. If the similarity is less than a first threshold, the beam can be reported. This process continues until M beams that need to be reported are determined, where M is a positive integer.

[0269] For example, with a first threshold of 0.95 and M = 2, the multiple beams include beam 1, beam 2, beam 3, beam 4, beam 5, and beam 6. The beams are sorted according to their reference signal received power as follows: beam 2, beam 3, beam 4, beam 5, beam 6, beam 1. Beam 2 has the highest reference signal received power among these beams; no beam has a higher power. Therefore, the first communication device can report beam 2. This can be understood as the similarity between the power spectrum of beam 2 and the power spectrum of a beam with a higher reference signal received power being 0, which is less than the first threshold. For beam 3, since the reference signal received power of beam 2 is greater than that of beam 3, the first communication device calculates the similarity between the power spectrum of beam 3 and the power spectrum of beam 2. If the similarity is 1, which is greater than the threshold, beam 3 can be considered... The beam 3 is a sidelobe beam of a strong target on beam 2, therefore beam 3 does not need to be reported. For beam 4, although the reference signal received power of beam 2 is greater than that of beam 4, and the reference signal received power of beam 3 is greater than that of beam 4, since beam 3 is not reported, the first communication device does not need to calculate the similarity between the power spectrum of beam 4 and the power spectrum of beam 3. It only calculates the similarity between the power spectrum of beam 4 and the power spectrum of beam 2. If the similarity is 0.89, which is less than the first threshold, the first communication device can report beam 4. At this point, the first communication device has determined that the two beams that need to be reported include beam 2 and beam 4 (i.e., the number of at least one beam indicated by the sixth information in S802 is 3), and the first communication device can stop the calculation.

[0270] For example, if M=3 and the first threshold is 0.95, and M=2, the multiple beams include beam 1, beam 2, beam 3, beam 4, beam 5, and beam 6. The result of sorting these multiple beams according to the reference signal received power is: beam 2, beam 3, beam 4, beam 5, beam 6, beam 1. Referring to the example above for M=2, the first communication device determines that beams 2 and 4 need to be reported according to the reference signal received power from high to low. Then, the first communication device continues to calculate the similarity between the power spectrum of beam 5 and the power spectrum of beam 2, and the similarity between the power spectrum of beam 5 and the power spectrum of beam 4. When both similarities are less than the first threshold, the first communication device can report beam 5. At this point, the first communication device has determined that the three beams to be reported include beam 2, beam 4, and beam 5 (i.e., the number of at least one beam indicated by the sixth information in S802 above is 3), and the first communication device can stop the calculation. When at least one of the two similarities is greater than the first threshold, the first communication device may not report beam 5. Then, the first communication device continues to calculate the similarity of the subsequent beams until the three beams that need to be reported are determined.

[0271] Optionally, the fifth beam is not only the beam with a higher reference signal received power than the fourth beam among the plurality of beams, but also an adjacent beam of the fourth beam, wherein the fourth beam is any one of the at least one beam. It should be understood that, generally, higher sidelobe power is more likely to be measured on an adjacent beam of a beam where a target exists. Therefore, the first communication device can calculate the similarity between the power spectrum of the fourth beam and the power spectra of other beams that meet the following conditions: the beam with a higher reference signal received power than the fourth beam and is adjacent to the fourth beam.

[0272] Optionally, the first communication device can independently determine the adjacent beams of each of the plurality of beams. Alternatively, the first communication device can receive fifth information from the second communication device, the fifth information being used to indicate the adjacent beams of each of the plurality of beams. Alternatively, the first communication device can receive fifth information from a network element in the core network responsible for sensing functions, the fifth information being used to indicate the adjacent beams of each of the plurality of beams.

[0273] For more information on the fifth information and adjacent beams, please refer to the description above, which will not be repeated here.

[0274] In order for the second communication device to more accurately determine the beam in which the target is located, the first communication device can also indicate more measurement information through the sixth information.

[0275] Optionally, the sixth information is also used to indicate the reference signal received power of each of the at least one beam.

[0276] Optionally, the sixth information is also used to indicate the sorting information or priority information of the at least one beam. Among the at least one beam, the beam with higher reference signal received power is sorted earlier or has higher priority; among the at least one beam, the beam with lower reference signal received power is sorted later or has lower priority.

[0277] Optionally, the first communication device can determine the number of beams that need to be reported, such as the value of M mentioned above. Alternatively, the first communication device can receive eighth information from the second communication device, which indicates the number of the at least one beam, i.e., the number of beams that need to be reported. Alternatively, the first communication device can receive eighth information from the network element responsible for sensing functions in the core network, which indicates the number of the at least one beam, i.e., the number of beams that need to be reported.

[0278] Optionally, in this embodiment, the reference signal received power of each beam can be the reference signal received power of each beam within a first Doppler range and / or a first time delay range. Here, the first Doppler range and / or the first time delay range are the desired Doppler range and / or time delay range to be measured, or the expected time delay and / or Doppler of the target by the sensing service. In this way, when performing sensing, the first communication device only needs to focus on the target within the first Doppler range and / or the first time delay range, which helps reduce the computational load and power consumption of the first communication device.

[0279] For example, the plurality of beams includes a sixth beam, the reference signal received power of the sixth beam being: the received power of the reference signal on the sixth beam within a first Doppler range, and / or, the received power of the reference signal on the sixth beam within a first time delay range.

[0280] Optionally, the first communication device may independently determine the first Doppler range and / or the first time delay range. Alternatively, the first communication device may receive fourth information from the second communication device, the fourth information indicating the first Doppler range and / or the first time delay range. Or, the first communication device may receive fourth information from a network element in the core network responsible for sensing functions, the fourth information indicating the first Doppler range and / or the first time delay range.

[0281] Optionally, the first communication device may report at least one beam whose reference signal received power meets the second threshold requirement. For example, the first communication device determines beams 2, 3, and 4 from beams 1 to beams 6 in ascending order of received power, wherein the reference signal received power of beam 4 is less than the second threshold. Therefore, the first communication device reports beams 2 and 3, that is, at least one beam among the multiple beams indicated by the sixth information in S802 above includes beams 2 and 3.

[0282] Optionally, the first communication device may determine the first threshold and / or the second threshold independently. Alternatively, the first communication device may receive seventh information from the second communication device, the seventh information indicating the first threshold and / or the second threshold. Alternatively, the first communication device may receive seventh information from a network element in the core network responsible for sensing functions, the seventh information indicating the first threshold and / or the second threshold.

[0283] Figure 9 is a schematic flowchart of a measurement reporting method 900 provided in an embodiment of this application. In method 900, the communication device (such as a first communication device and a second communication device) can be a communication equipment or a module (e.g., a processor, chip, chip system, circuit, etc.) configured in a communication equipment. The first communication device and the second communication device are different communication devices.

[0284] For example, the first communication device may be a terminal device or a module configured in a terminal device, and the second communication device may be a network device or a module configured in a network device.

[0285] For example, the first communication device may be a terminal device or a module configured in the terminal device, and the second communication device may be a terminal device or a module configured in the terminal device.

[0286] Method 900 includes, but is not limited to, S901 and S902. The steps are described in detail below.

[0287] S901, the second communication device sends reference signals on multiple beams to the first communication device. Correspondingly, the first communication device receives the reference signals on the multiple beams.

[0288] For an explanation of this step, please refer to the description of S701 above; it will not be repeated here.

[0289] S902, the first communication device sends ninth information to the second communication device. The ninth information is used to indicate the top X beams with the highest reference signal reception power among the plurality of beams, and the similarity between the power spectrum of the seventh beam and the power spectrum of the eighth beam among the top X beams. The seventh beam is any one of the top X beams, and the eighth beam is the beam among the top X beams with a higher reference signal reception power than the seventh beam. X is a positive integer.

[0290] In one implementation, the ninth information may include the identifier of each beam in the at least one beam, with different beams corresponding to different identifiers, that is, the first communication device can indicate the beam by the beam identifier.

[0291] In another implementation, the ninth information may include an identifier of a reference signal on each of the at least one beam, with one reference signal carried on each beam and one identifier corresponding to each reference signal. That is, the first communication device can obtain the identifier of the reference signal on the beam from the indicating beam.

[0292] In this embodiment, while reporting the top X beams with the highest received reference signal power among the multiple beams, the first communication device can also report the similarity between the power spectrum of the seventh beam and the power spectrum of the eighth beam to avoid confusion caused by the sidelobe beams of strong targets affecting the main lobe beams of weak targets. Thus, the second communication device can determine whether the seventh beam is a sidelobe beam of a strong target or a main lobe beam of a weak target based on the similarity between the power spectra of the seventh and eighth beams. For example, it can compare the similarity with a first threshold. If the similarity is greater than the first threshold, it indicates a high similarity between the seventh and eighth beams. It can be assumed that the seventh beam with lower received reference signal power is a sidelobe beam of a strong target on the eighth beam with higher received reference signal power. The target may not exist on the seventh beam, and its received power mainly leaks from the eighth beam. This helps the second communication device to more accurately identify the beam where the target is located.

[0293] For example, the multiple beams include beam 1, beam 2, beam 3, beam 4, beam 5, and beam 6. The top X beams with the highest reference signal received power include beam 2, beam 3, and beam 4. For example, as shown in Figure 6, the reference signal received power of beam 2 is higher than that of beam 3, and the reference signal received power of beam 3 is higher than that of beam 4. The first communication device can report beams 2, 3, and 4 to the second communication device, and also report the similarity between the power spectrum of beam 3 and the power spectrum of beam 2, the similarity between beam 4 and beam 2, and the similarity between beam 4 and beam 3. For beam 2, the first communication device may not report the similarity corresponding to beam 2, meaning that beam 2 is the beam with the highest reference signal received power among the reported top X beams, or the reported similarity corresponding to beam 2 is 0. If the similarity between the power spectrum of beam 3 and the power spectrum of beam 2 is 1, which is greater than the first threshold, then the second communication device can determine that beam 3 is a sidelobe beam of a strong target on beam 2. If the similarity between the power spectrum of beam 4 and the power spectrum of beam 2 is less than the first threshold, and the similarity between the power spectrum of beam 4 and the power spectrum of beam 3 is less than the first threshold, then the second communication device can determine that beam 4 is a mainlobe beam of a weak target.

[0294] Optionally, the eighth beam is not only the beam with a higher received reference signal power than the seventh beam among the plurality of beams, but also an adjacent beam of the seventh beam, wherein the seventh beam is any one of the first X beams. It should be understood that, generally, higher sidelobe power is more likely to be measured on an adjacent beam of a beam where a target is present. Therefore, the first communication device may report the similarity between the power spectrum of the seventh beam and the power spectra of other beams that meet the conditions, wherein the beams that meet the conditions are: beams with a higher received reference signal power than the seventh beam and adjacent to the seventh beam.

[0295] Optionally, the first communication device can independently determine the adjacent beams of each of the plurality of beams. Alternatively, the first communication device can receive fifth information from the second communication device, the fifth information being used to indicate the adjacent beams of each of the plurality of beams. Alternatively, the first communication device can receive fifth information from a network element in the core network responsible for sensing functions, the fifth information being used to indicate the adjacent beams of each of the plurality of beams.

[0296] For more information on the fifth information and adjacent beams, please refer to the description above, which will not be repeated here.

[0297] Optionally, the first communication device can determine the value of X independently. Alternatively, the first communication device can receive tenth information from the second communication device, which indicates the value of X. Alternatively, the first communication device can receive tenth information from a network element in the core network responsible for sensing functions, which indicates the value of X.

[0298] Optionally, in this embodiment, the reference signal received power of each beam can be the reference signal received power of each beam within a first Doppler range and / or a first time delay range. Here, the first Doppler range and / or the first time delay range are the desired Doppler range and / or time delay range to be measured, or the expected time delay and / or Doppler of the target by the sensing service. In this way, when performing sensing, the first communication device only needs to focus on the target within the first Doppler range and / or the first time delay range, which helps reduce the computational load and power consumption of the first communication device.

[0299] For example, the plurality of beams includes a ninth beam, the reference signal received power of the ninth beam being: the received power of the reference signal on the ninth beam within a first Doppler range, and / or, the received power of the reference signal on the ninth beam within a first time delay range.

[0300] It should be understood that in the second implementation described in method 800 above, the determination of the similarity between each of the first X beams and the first threshold is performed by the first communication device. Based on the magnitude of the similarity between each beam and the first threshold, the first communication device determines at least one beam to be reported from the first X beams. The first communication device does not need to report the similarity, which helps reduce the signaling overhead of the first communication device. However, in method 900 above, the determination of the similarity between each of the first X beams and the first threshold is performed by the second communication device. This allows the second communication device to more accurately determine the beam where the target is located.

[0301] It should be understood that the similarity of a beam described in this application includes the similarity between the power spectrum of the beam and the power spectrum of a beam with a higher received power than its reference signal.

[0302] Optionally, the similarity of a beam includes the similarity between the power spectrum of the beam and the power spectrum of a beam that has a higher received power than its reference signal and is adjacent to the beam.

[0303] It should be understood that the sequence number of each process does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
