Method and apparatus for sensing communication

[0001] The present application claims priority to the Chinese patent application No. 202410482426.9, filed on April 19, 2024, and entitled "Method and apparatus for sensing communication", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] Embodiments of the present application relate to the field of communication, in particular to a method and apparatus for sensing communication. BACKGROUND

[0003] Wireless sensing and communication integration is one of the key technologies of the next stage of 5th generation (5G) technology evolution (5G-Advanced), which can be widely used in typical application scenarios such as intelligent transportation, intelligent low-altitude, and intelligent network. Wireless sensing and communication integration realizes the unified design of communication and sensing functions through signal joint design and hardware sharing.

[0004] Sensing in wireless sensing and communication integration can be understood as wireless sensing technology based on a communication system. A device with wireless sensing and communication integration function (such as a sensing and communication integration device) can emit a wireless signal to a target area or a target object and receive a reflected echo signal from the object, and obtain corresponding sensing measurement quantities such as the number, position, and moving speed of the target object, and the identification of the target object identity through analysis of the received signal.

[0005] In wireless sensing and communication integration, single-station sensing (such as sensing based on a sensing signal sent by a single sensing and communication integration device) is usually used. However, the sensing capability of single-station sensing is limited, so multi-station cooperation can be considered to improve the sensing performance. However, there is currently no related solution to how to implement multi-station cooperation. SUMMARY

[0006] Embodiments of the present application provide a method and apparatus for sensing communication for implementing multi-station cooperation to improve the sensing performance.

[0007] In a first aspect, a method for sensing communication is provided. The method can be performed by a first network element, or by a component of the first network element, such as a processor, circuit, chip, or chip system of the first network element, or by a logic module or software that can implement all or part of the function of the first network element. The method includes determining first indication information, the first indication information being used by a second network element to determine a first beam, the first beam being used to transmit a second sensing signal, wherein the first indication information indicates a first region, the first region being a region for sensing by the first network element, or the first indication information indicates first beam information; and transmitting the first indication information.

[0008] Based on the scheme, the first network element can indicate the area (i.e., the first area) for which it performs sensing to the second network element, so that the second network element can determine the beam (i.e., the first beam) for transmitting the second sensing signal according to the first area. Alternatively, the first network element can indicate the first beam information to the second network element, so that the second network element can determine the first beam according to the first beam information. For example, the first network element can set the first beam information according to the first area, and at this time, the second network element determining the first beam according to the first beam information can also be understood as: the second network element determining the first beam according to the first area. For example, the coverage of the first beam determined by the second network element can include the first area. Therefore, the second network element can perform sensing in the first area through the second sensing signal, that is, the first network element and the second network element can both perform sensing in the first area, that is, multiple network elements (such as the first network element and the second network element) can perform cooperative sensing in the first area. Compared with the single-station sensing scheme, the sensing accuracy in the first area can be improved, and the sensing performance can be improved.

[0009] In a possible design, after the first indication information is sent to the second network element, the sensing communication method further includes: sending the first sensing signal through the second beam; receiving a back echo signal of the first sensing signal; and determining first measurement information according to the back echo signal of the first sensing signal, the first measurement information including a first measurement receiving signal result or first point cloud information, the first measurement receiving signal result being information obtained by measuring the back echo signal of the first sensing signal, and the first point cloud information being determined according to the first measurement receiving signal result.

[0010] In a possible design, the sensing communication method further includes: receiving a back echo signal of the second sensing signal, the second sensing signal being carried in the first beam; and determining second measurement information according to the back echo signal of the second sensing signal, the second measurement information including a second measurement receiving signal result or second point cloud information, the second measurement receiving signal result being information obtained by measuring the back echo signal of the second sensing signal, and the second point cloud information being determined according to the second measurement receiving signal result.

[0011] According to the first measurement information and the second measurement information, third measurement information is determined, the third measurement information including a third measurement receiving signal result or third point cloud information, the third measurement receiving signal result being determined according to the first measurement receiving signal result and the second measurement receiving signal result, and the third point cloud information being determined according to the first point cloud information and the second point cloud information.

[0013] Based on the two possible designs above, after obtaining the first measurement information and the second measurement information, the first network element can fuse the first measurement information and the second measurement information to obtain fused information (i.e., the third measurement information), and further, can determine the sensing result of the first region according to the third measurement information, which can improve the sensing accuracy in the first region compared with the sensing result of the first region determined based on the first measurement information.

[0014] In a possible design, before receiving the second measurement information from the second network element, the method further includes: sending second indication information to the second network element, the second indication information indicating a fusion type, the fusion type including signal fusion or point cloud fusion; wherein, when the fusion type includes the signal fusion, the second measurement information includes the second measurement results of the second received signal; and when the fusion type includes the point cloud fusion, the second measurement information includes the second point cloud information.

[0015] Based on this possible design, the first network element can send the fusion type to the second network element, so that the second measurement information determined by the second network element meets the fusion requirement of the first network element (i.e., the parameters included in the second measurement information are the same as the parameters included in the first measurement information), thereby, after receiving the second measurement information, the first network element does not need to process the type of parameters in the second measurement information, and can directly fuse the first measurement information, which reduces the time delay of fusion and improves the sensing efficiency.

[0016] In a possible design, the third measurement results of the third received signal are determined according to a first proportion, the first measurement results of the first received signal, a second proportion, and the second measurement results of the second received signal, wherein the first proportion is the overlapping proportion of the coverage area of the second beam and the first region, and the second proportion is the overlapping proportion of the coverage area of the first beam and the first region.

Thus, the first network element and the second network element can perform sensing in the first area based on the second beam and the first beam, respectively, i.e., multiple network elements (such as the first network element and the second network element) can perform cooperative sensing in the first area. Compared with the scheme of single-station sensing (such as sensing by the first network element or the second network element), the sensing accuracy in the first area can be improved, and the sensing performance can be improved.

[0032] Based on the scheme, the second network element can determine the first beam based on the first area or the first beam information. Specifically, the first beam information can be determined according to the first area. At this time, the second network element determines the first beam according to the first beam information can also be understood as: the second network element determines the first beam according to the first area. For example, the coverage range of the first beam determined by the second network element can include the first area. Therefore, the second network element transmits the second sensing signal through the first beam, which means that the second network element performs sensing in the first area through the second sensing signal. That is, the first network element and the second network element can both perform sensing in the first area, that is, multiple network elements (such as the first network element and the second network element) can perform cooperative sensing in the first area.

[0085] In the description of the present application, unless otherwise specified, " / " means that the objects before and after the " / " are in an "or" relationship, for example, A / B can mean A or B; "and / or" in the present application is only a description of the relationship between the associated objects, which means that there can be three relationships, for example, A and / or B, which can mean: A exists alone, A and B exist together, and B exists alone, where A and B can be singular or plural.

[0086] In the description of the present application, unless otherwise specified, "multiple" means two or more than two. "At least one of the following" or the like means any combination of the items, including any combination of single item or multiple items. For example, at least one of a, b, or c can mean a, b, c, a-b, a-c, b-c, or a-b-c, where a, b, and c can be single or multiple.

[0087] In addition, in order to facilitate clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second", etc. are used to distinguish the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first", "second", etc. do not limit the quantity and execution order, and the words "first", "second", etc. also do not mean necessarily different.

[0088] In the embodiments of the present application, the words "exemplary" or "for example" are used to mean serving as an example, an instance, or an illustration. Any embodiment or design presented as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or superior to other embodiments or design solutions. In fact, the use of the words "exemplary" or "for example" is intended to present related concepts in a specific manner, facilitating understanding.

[0089] It can be understood that the "embodiments" mentioned throughout the specification mean that the specific features, structures or characteristics related to the embodiments are included in at least one embodiment of the present application. Therefore, the various embodiments throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner. It can be understood that in various embodiments of the present application, the size of the serial number of each process does not mean the execution order, and the execution order of each process should be determined according to its function and inherent logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0090] It can be understood that in the present application, "when" and "if" both refer to making corresponding processing under certain objective circumstances, not limited to time, and do not require judgment actions when implementing, nor mean that there are other limitations.

[0091] It can be understood that some optional features in the embodiments of the present application can be implemented independently in some scenarios, without relying on other features, such as the scheme currently based on, to solve the corresponding technical problems and achieve the corresponding effects. In some scenarios, the features can be combined with other features according to the needs.

The to-be-indicated information can also be only indicated in part, and the other part of the to-be-indicated information is known or agreed in advance. For example, the indication of a specific information can be achieved by means of the arrangement order of various information agreed in advance (for example, specified by a protocol), thereby reducing the indication overhead to a certain extent. At the same time, the common part of each information can be identified and uniformly indicated, so as to reduce the indication overhead caused by separately indicating the same information. In addition, the specific indication manner can also be various existing indication manners, for example but not limited to, the above-mentioned indication manners and various combinations thereof. The specific details of various indication manners can refer to the prior art, and will not be described herein. As can be seen from the above, for example, when multiple information of the same type needs to be indicated, the indication manner of different information can be different. In the specific implementation process, the required indication manner can be selected according to the specific needs, and the selected indication manner is not limited by the embodiments of the present application, so that the indication manner involved in the embodiments of the present application should be understood as covering various methods that can enable the to-be-indicated party to know the to-be-indicated information. The to-be-indicated information can be sent as a whole, or can be sent separately in multiple sub-information, and the sending period or sending occasion of the sub-information can be the same or different. The specific sending method is not limited by the present application. The sending period or sending occasion of the sub-information can be predefined, for example, predefined according to a protocol, or configured by the transmitting end device by sending configuration information to the receiving end device.

[0093] In the present application, the same or similar parts between various embodiments can be mutually referred to, unless otherwise specified. In the present application, the terms and / or descriptions of different embodiments are consistent and can be mutually referred to, unless otherwise specified and logically conflicted, and different embodiments can be combined to form new embodiments according to their inherent logical relationship. The implementation modes of the present application described below do not constitute a limitation on the protection scope of the present application.

[0094] In order to facilitate understanding of the technical solutions of the embodiments of the present application, first, a brief introduction of the related technologies of the present application is given as follows.

[0095] 1、Synchronization signal / physical layer broadcast channel block (SSB (or SS / PBCH block)):

[0096] For the convenience of description, the synchronization signal / physical layer broadcast channel block is referred to as SSB below, and unified description is given here without further elaboration.

[0097] The base station usually transmits SSB periodically. One SSB period includes one SSB burst set, and the relative position of the SSB burst set is the same in each SSB period. Therefore, the SSB period can also be understood as the period of the SSB burst set. One SSB burst set includes multiple SSBs. Each SSB has an index. In one SSB period, the indexes of different SSBs are different. For example, one SSB burst set includes K SSBs, and the indexes of the K SSBs are respectively denoted as SSB#0, SSB#1, …, SSB#K-1, where K is a positive integer and K≥2.

[0098] For the base station, the base station transmits SSB using spatial domain transmission parameters (that is, beams used for transmitting signals, or also referred to as transmission beams). Specifically, the base station can use different spatial domain transmission parameters to transmit different SSBs in the same period. For example, the base station can use spatial domain transmission parameter #0 (or also referred to as beam #0, or also referred to as transmission beam #0) to transmit SSB#0; similarly, the base station can use spatial domain transmission parameter #1 to transmit SSB#1, …, and use spatial domain transmission parameter #K-1 to transmit SSB#K-1. Wherein, the corresponding beam directions of spatial domain transmission parameter #0, spatial domain transmission parameter #1, …, spatial domain transmission parameter #K-1 can be different, so that the base station covers terminal devices in different beam directions. That is, the indexes of different SSBs correspond to different spatial domain parameters, that is, each SSB index corresponds to one spatial domain transmission parameter.

[0099] 2、Positioning reference signal (PRS) resource:

[0100] PRS is defined for new radio (NR) positioning, and the set of resource elements (REs) used for the transmission of PRS can be referred to as a PRS resource.

[0101] A PRS resource set is a set of PRS resources for transmission of PRS signals, where each PRS resource has a PRS resource identifier (ID). Each PRS resource ID is associated with a single beam (or beam ID) transmitted from a single transmission reception point (TRP) (where a TRP can transmit one or more beams). That is, different PRS resources can be transmitted on different beams, that is, each PRS resource corresponds to a beam respectively.

[0102] 3. Wireless sensing integration technology:

[0103] Wireless sensing integration is one of the key technologies of the next stage of 5th generation (5G) technology evolution (5G-Advanced), which can be widely used in typical application scenarios such as intelligent transportation, intelligent low-altitude, and intelligent network. Through signal joint design and / or hardware sharing, the communication and sensing functions are designed uniformly, thereby obtaining gains in spectrum sharing, cost reduction, and simplified deployment. Wireless sensing integration can also be described as communication-sensing fusion.

[0104] Sensing in wireless sensing integration can be understood as wireless sensing technology based on a communication system. A device with wireless sensing integration function (such as a sensing integration device) can emit a wireless signal to a target area or target object and receive a reflected echo signal from the object, and obtain corresponding sensing measurement quantities such as the number, position, and moving speed of the target object, and the identification of the target object identity through analysis of the received signal.

[0105] Specifically, the sensing integration device can be a terminal device or an access network device. The sensing integration device can implement per-area sensing and per-object sensing, that is, wireless sensing integration can be applied to per-area sensing scenarios and per-object sensing scenarios. That is, the sensing service performed by the sensing integration device can also be divided into per-area sensing service and per-object sensing service.

[0106] Among them, per-object sensing is for specific target objects such as vehicles, unmanned aerial vehicles (UAVs), etc. The per-object application scenario or per-object sensing service can include sensing the target object. Specifically, the sensing integration device can use wireless sensing integration technology to sense the target object based on the identification of the target object.

[0107] The region-oriented perception is for a region, which can be understood as a geographical region, such as a city low altitude, a city road, a factory, and the like, or can be understood as a time region (or a time range). Among them, for the geographical region, the region-oriented application scenario or the region-oriented perception service can include: perception of an object in a region; such as perception of a UAV in a preset range in a city low altitude. Or, perception of a target object in a region; such as perception of a moving track and a moving speed of one or more target vehicles on a city road.

[0108] For the time region, the region-oriented application scenario or the region-oriented perception service can include: breath detection, fitness monitoring, and / or gesture (or posture) recognition, and the like for a target task. Specifically, the all-in-one sensing device can perceive a channel change, and further, through analysis of a signal change, breath detection, fitness monitoring, gesture / posture recognition, and the like are achieved. Or, detection of weather, specifically, the all-in-one sensing device perceives signal attenuation in a communication link, and further, a corresponding weather index is obtained by using a relationship between the signal attenuation and the weather index to achieve detection of the weather.

[0109] It can be understood that the above exemplary lists implementation of the application scenario of the all-in-one sensing device, and the application scenario of the all-in-one sensing device can also include other application scenarios in addition to the above examples, which are not limited by the embodiments of the present application.

[0110] Specifically, the perception service can include different implementation manners. Taking the target-oriented perception service as an example, if the perception service is to perceive a target object, as shown in FIG. 1, the perception service can include the following six implementation manners:

[0111] (1) A single access network device is used to perceive the target object. Specifically, as shown in (a) of FIG. 1, the access network device can send a wireless signal to the target object, and receive a backwave signal reflected by the target object, so as to obtain a measurement quantity of the target object, and achieve perception of the target object.

[0112] (2) A single terminal device is used to perceive the target object. Specifically, as shown in (b) of FIG. 1, the terminal device can send a wireless signal to the target object, and receive a backwave signal reflected by the target object, so as to obtain a measurement quantity of the target object, and achieve perception of the target object.

[0113] (3) Two access network devices (access network device #1 and access network device #2) are used to perceive the target object. Specifically, as shown in (c) of FIG. 1, the access network device #1 can send a wireless signal to the target object, and correspondingly, the access network device #2 receives a backwave signal reflected by the target object, so as to obtain a measurement quantity of the target object, and achieve perception of the target object.

[0114] (4), using two terminal devices (terminal device #1 and terminal device #2) to perceive the target object. Specifically, as shown in (d) of FIG. 1, the terminal device #1 can send a wireless signal to the target object, and correspondingly, the terminal device #2 receives the echo signal reflected by the target object, so as to obtain the measurement quantity of the target object, and realize the perception of the target object.

[0115] (5), using one terminal device and one access network device to perceive the target object, wherein the access network device is configured to send a signal, and the terminal device is configured to receive a signal. Specifically, as shown in (e) of FIG. 1, the access network device can send a wireless signal to the target object, and correspondingly, the terminal device receives the echo signal reflected by the target object, so as to obtain the measurement quantity of the target object, and realize the perception of the target object.

[0116] (6), using one terminal device and one access network device to perceive the target object, wherein the terminal device is configured to send a signal, and the access network device is configured to receive a signal. Specifically, as shown in (f) of FIG. 1, the terminal device can send a wireless signal to the target object, and correspondingly, the access network device receives the echo signal reflected by the target object, so as to obtain the measurement quantity of the target object, and realize the perception of the target object.

[0117] The above six implementation manners can also be referred to as different perception modes, that is, the perception service can be implemented based on the above six perception modes. In order to facilitate description, in the following embodiments, the above six implementation manners are collectively referred to as six perception modes, which are uniformly described here and will not be described again.

[0118] For example, the perception mode shown in (a) of FIG. 1 can be referred to as perception mode #1, the perception mode shown in (b) of FIG. 1 can be referred to as perception mode #2, the perception mode shown in (c) of FIG. 1 can be referred to as perception mode #3, the perception mode shown in (d) of FIG. 1 can be referred to as perception mode #4, the perception mode shown in (e) of FIG. 1 can be referred to as perception mode #5, and the perception mode shown in (f) of FIG. 1 can be referred to as perception mode #6.

[0119] For example, in the above perception mode #1 and perception mode #2, one device sends a perception signal and receives the echo signal of the perception signal to realize the perception of the target object, so it can be considered that the access network device in the perception mode #1 or the terminal device in the perception mode #2 realizes the perception of the target object through self-generation and self-reception; that is, one device realizes the perception of the target object by sending a perception signal and receiving the echo signal of the perception signal; that is, it can be considered that the perception mode of the device is self-generation and self-reception.

[0120] In addition, in the above-mentioned perception mode #3 to the perception mode #6, the perception of the target object is achieved by two devices, one of which is used to send a perception signal, and the other is used to receive the echo signal of the perception signal. Therefore, it can be considered that the one device achieves the perception of the target object by self-receiving; that is, one of the two devices sends a perception signal, but does not receive the echo signal of the perception signal, which is received by the other device; that is, it can be considered that the perception mode of the one device is self-receiving.

[0121] Based on the above six perception modes, in the wireless sensing and communication integration, single station sensing is usually adopted (such as sensing based on a perception signal sent by a single sensing and communication integration device), but the sensing capability of single station sensing is limited. For example, when the target object is at the edge of the signal coverage area of the sensing and communication integration device, the accuracy of the target object perceived by the sensing and communication integration device is reduced, and the sensing and communication integration device may not perceive the target object, resulting in reduced sensing performance. Therefore, it can be considered to use a multi-station cooperation mode to improve the sensing performance. However, how to achieve multi-station cooperation currently does not have a related solution.

[0122] Therefore, the present application proposes a perception communication method and device. The first network element can indicate the area (i.e. the first area) for the second network element to perform perception, so that the second network element can determine the beam (i.e. the first beam) for transmitting the second perception signal according to the first area. Alternatively, the first network element can indicate the first beam information to the second network element, so that the second network element can determine the first beam according to the first beam information. For example, the first network element can set the first beam information according to the first area, and at this time, the second network element determining the first beam according to the first beam information can also be understood as: the second network element determining the first beam according to the first area. For example, the coverage range of the first beam determined by the second network element can include the first area. Therefore, the second network element can perform perception in the first area through the second perception signal, that is, the first network element and the second network element can both perform perception in the first area, that is, multiple network elements can perform cooperative perception in the first area; compared with the single station sensing scheme, the sensing accuracy in the first area can be improved, and the sensing performance can be improved.

[0123] The technical solutions provided in the present application can be applied to various communication systems, which can be a 3rd generation partnership project (3GPP) related cellular system, for example, a 4th generation (4G) long term evolution (LTE) system, an LTE-Advanced (LTE-A) system, a 5G NR system, a vehicle to everything (V2X) system, a system with mixed networking of LTE and NR, or a device-to-device (D2D) system, a machine to machine (M2M) communication system, an internet of things (IoT), and other next-generation communication systems, such as a 6th generation (6G) communication system, and the like.

[0124] Alternatively, the communication system can also be a non-3GPP communication system, for example, an open radio access network (O-RAN or ORAN), a cloud radio access network (CRAN), a wireless fidelity (WiFi) system, or can also be a communication system combined with multiple communication systems described above, which is not limited in the present application.

[0125] It should be understood that the above-mentioned communication system applicable to the present application is only an example, and the communication system applicable to the present application is not limited thereto. Hereinafter, the following will not be described in detail.

[0126] The present application provides an exemplary communication system. The communication system can include a first network element and at least one second network element. The first network element is configured to perform sensing, and the second network element is configured to assist the first network element to perform sensing.

[0127] For example, the first network element configured to perform sensing can be understood as that the first network element can send a sensing signal. Similarly, the second network element can also send a sensing signal. Specifically, the sensing signal can be understood as a wireless signal for sensing.

[0128] It should be understood that the sensing signal sent by the first network element is different from the sensing signal sent by the second network element. For the convenience of description, the sensing signal sent by the first network element is referred to as the "first sensing signal", and the sensing signal sent by the second network element is referred to as the "second sensing signal", which is uniformly described hereinafter and will not be described in detail.

[0129] Exemplarily, the first sensing signal can also be referred to as a first signal, a first wireless signal, a first reference signal, and the like; similarly, the second sensing signal can also be referred to as a second signal, a second wireless signal, a second reference signal, and the like, which are not limited in the present application.

[0130] Optionally, the communication system can further include a third network element configured to provide a sensing function (SF) for the first network element and the second network element.

[0131] Exemplarily, the third network element can be deployed in a core network (CN). For example, the third network element can be deployed in a location management function (LMF) network element or together with the LMF network element; at this time, the third network element can also be referred to as the LMF network element. Alternatively, the third network element can also be independently deployed in the CN, at this time, the first network element can also be referred to as the SF network element.

[0132] For the convenience of description, the network element "configured to provide the SF for the first network element and the second network element" will be collectively referred to as the SF network element hereinafter, which will be uniformly described hereinafter and will not be described again. It can be understood that the above exemplarily lists possible names of the third network element, and the third network element can also be referred to as other names, such as a sensing function network element, a sensing requirement network element, a sensing management network element, and the like, which are not limited in the embodiments of the present application.

[0133] In a possible implementation manner, the first network element can be deployed in an access network device or a terminal device.

[0134] Optionally, in the possible implementation manner, the second network element can also be deployed in the access network device or the terminal device.

[0135] Exemplarily, when the first network element and the second network element are both deployed in the access network device, the first network element and the second network element are deployed in different access network devices. Similarly, when the first network element and the second network element are both deployed in the terminal device, the first network element and the second network element are deployed in different terminal devices.

[0136] Referring to FIG. 2, a schematic diagram of a communication architecture provided by an embodiment of the present application is shown. Specifically, the first network element can be deployed in any of the access network device #1, the access network device #2, and the terminal device in FIG. 2. Wherein, in the case that the first network element is deployed in the access network device #1, the second network element can be deployed in the access network device #2 or the terminal device; in the case that the first network element is deployed in the access network device #2, the second network element can be deployed in the access network device #1 or the terminal device; in the case that the first network element is deployed in the terminal device, the second network element can be deployed in the access network device #1 or the access network device #2, or the second network element can also be deployed in another terminal device (not shown in FIG. 2) other than the terminal device where the first network element is located.

[0137] In addition, the third network element can be the SF network element in FIG. 2. Wherein, in the case that the first network element is deployed in the terminal device, the first network element can communicate with the third network element through the access network device (such as the access network device #1 or the access network device #2 shown in FIG. 2) associated therewith. In the case that the first network element is deployed in the access network device (such as the access network device #1 or the access network device #2), the first network element can directly communicate with the third network element (i.e., the SF network element) (such as the first network element is directly connected with the third network element), or the first network element can communicate with the third network element through the user plane function (UPF) network element and / or the access and mobility management function (AMF) network element. For example, in the case that the third network element is the LMF network element, the access network device (i.e., the first network element) can communicate with the third network element through the AMF network element.

[0138] It can be understood that the access network device associated with the terminal device can be understood as the access network device providing service for the terminal device.

[0139] For example, the access network device can communicate with the UPF network element through the NG-U interface; the access network device can communicate with the AMF network element through the NG-C interface; the access network devices can communicate with each other through the Xn interface, and the terminal device can communicate with the access network device through the Uu interface.

[0140] Exemplarily, the third network element can also be divided into an SF control plane (SF-C) network element and an SF user plane (SF-U) network element. For example, when the access network device implements communication with the third network element through the UPF network element and the AMF network element, the access network device can implement communication with the SF-U network element through the UPF network element and implement communication with the SF-C network element through the AMF network element. Alternatively, when the access network device directly communicates with the SF network element (for example, the access network device is directly connected to the SF network element), the access network device can directly communicate with the SF-U network element and / or the SF-C network element.

[0141] Specifically, the UPF network element refers to a user plane network element deployed in the CN, used to carry data traffic, and mainly responsible for forwarding traffic between the wireless access network and the Internet, reporting traffic usage, quality of service (Qos) policy implementation, and the like. The AMF network element refers to a network element deployed in the CN to meet the 5G standard and provide services for the access and mobility management function of the terminal device; and is mainly responsible for mobility management in the mobile network, such as user location update, user registration network, user handover, and the like.

[0142] It can be understood that the communication between the access network device associated with the first network element and the third network element is similar to the implementation of the communication between the first network element and the third network element when the first network element is the access network device, and specific implementation can be referred to the related description of the communication between the first network element and the third network element when the first network element is the access network device, which will not be described here.

[0143] In another possible implementation, the first network element can be deployed in a device or apparatus capable of controlling or managing a device or apparatus capable of performing a sensing service.

[0144] In this application, the device or apparatus capable of controlling or managing a device or apparatus capable of performing a sensing service can be referred to as a sensing control (SC) network element; or other names, such as a sensing control apparatus, a control network element, a sensing control node, an edge sensing function, an edge control network element, an edge control node, and the like, which are not limited by the embodiments of the present application. Optionally, in this possible implementation, the second network element can be deployed in any one of the SC network element, the access network device, or the terminal device.

[0145] Exemplarily, when the first network element and the second network element are both deployed in the SC network element, the first network element and the second network element are deployed in different SC network elements.

[0146] For convenience of description, the network element of "controlling or managing a device or apparatus capable of performing a sensing service" will be collectively referred to as an SC network element, which will be uniformly described here and will not be described again.

[0147] As an example, the SC network element can also be divided into an SC control plane (SC-C) network element and an SC user plane (SC-U) network element. Therefore, the communication between the SC network element and the device or apparatus managed or controlled by the SC network element can be understood as the communication between the device or apparatus managed or controlled by the SC network element and the SC-C network element or the SC-U network element.

[0148] As an example, the sensing performed by the SC network element can be understood as the sensing performed by the device or apparatus managed or controlled by the SC network element (i.e., the device or apparatus capable of performing sensing services). As an example, the SC network element can be independently deployed, i.e., the first network element can be independently deployed.

[0149] Referring to (a) in FIG. 3, a schematic diagram of another communication architecture provided by the embodiments of the present application is shown. In (a) in FIG. 3, the first network element can be deployed in the SC network element, the second network element can be deployed in the access network device #1 or the access network device #2, or the second network element can also be deployed in another SC network element (not shown in (a) in FIG. 3) other than the SC network element where the first network element is located; and the third network element can be the SF network element. The first network element can control or manage the access network device #1 and the access network device #2, i.e., the access network device #1 and the access network device #2 can communicate with the third network element through the first network element (i.e., the second network element can communicate with the third network element through the first network element); at this time, the access network device #1 and the access network device #2 are indirectly connected with the third network element through the first network element. In addition, the access network device can also be directly connected with the third network element without the first network element, such as the access network device #3 (e.g., the second network element) which can be directly connected with the third network element. As another example, the SC network element can be deployed in the access network device, i.e., the first network element can be deployed in the access network device.

[0150] Referring to (b) of FIG. 3, a schematic diagram of another communication architecture provided by the embodiment of the present application is shown. In (b) of FIG. 3, the third network element is an SF network element, the first network element can be deployed in an SC network element, and the first network element is deployed in an access network device (such as access network device #1); the second network element can be deployed in an access network device #2 or an access network device #3, or the second network element can be deployed in a terminal device (not shown in (b) of FIG. 3). In the case where the second network element is deployed in the access network device #2 or the access network device #3, it means that the access network device #1 can control or manage the access network device #2 and the access network device #3, and the access network device #2 and the access network device #3 can communicate with the third network element through the access network device #1 (that is, the second network element can communicate with the third network element through the first network element). At this time, the access network device #2 and / or the access network device #3 (such as the second network element) are indirectly connected with the third network element through the access network device #1 (that is, the first network element).

[0151] In the case where the second network element is deployed in the terminal device, the access network device providing service for the second network element can be any one of the access network device #1, the access network device #2, and the access network device #3, or the access network device providing service for the second network element can be another access network device (not shown in (b) of FIG. 3) other than the access network device #1, the access network device #2, and the access network device #3, and at this time, the access network device #1 is also used to manage or control the access network device providing service for the second network element. The second network element can communicate with the first network element through the access network device providing service for the second network element, and further communicate with the third network element. The specific implementation can refer to the related description of the single SC network element in the above (a) of FIG. 3 and (b) of FIG. 3, and will not be described here.

[0152] It can be understood that the above (a) of FIG. 3 and (b) of FIG. 3 exemplarily describe the implementation of a single SC network element, and the SF network element can also communicate with multiple SC network elements, and the multiple SC network elements can also communicate with each other. The implementation of each SC network element in the multiple SC network elements can refer to the related description of the single SC network element in the above (a) of FIG. 3 and (b) of FIG. 3, and will not be described here.

[0153] The above two possible implementation manners can also be integrated, that is, the embodiment of the present application can also be applied to a communication architecture in which the above two possible implementation manners are integrated. That is, the communication architecture shown in FIG. 2 can also include an SC network element; at this time, the first network element can be deployed in the SC network element, the second network element can be deployed in the SC network element, the access network device, or the terminal device, and the third network element is an SF network element.

[0154] Exemplarily, in the case that the SC network element is independently deployed, in combination with the communication architecture shown in (a) of FIG. 2 and FIG. 3, the SC network element can be deployed between the access network device and the SF network element; specifically, taking the example that the access network device #1 and the access network device #2 in FIG. 2 are managed or controlled by the same SC network element, as shown in (a) of FIG. 4, the access network device #1 and the access network device #2 can both achieve communication with the SF network element through the SC network element; in addition, in the case that the SC network element is divided into an SC-C network element and an SC-U network element, the access network device #1 and the access network device #2 can achieve communication with the SF network element through the SC-C network element or the SC-U network element; further, in the case that the SF network element is divided into an SF-C network element and an SF-U network element, the access network device #1 and the access network device #2 can achieve communication with the SF-C network element through the SC-C network element, and / or, or the access network device #1 and the access network device #2 achieve communication with the SF-U network element through the SC-U network element.

[0155] The (a) of FIG. 4 above takes the example that the access network device #1 and the access network device #2 in FIG. 2 are managed or controlled by the same SC network element for introduction, actually, the access network device #1 and the access network device #2 in FIG. 2 can also be managed or controlled by different SC network elements, for example, the access network device #1 can be managed or controlled by the SC network element #1, and the access network device #2 can be managed or controlled by the SC network element #2; at this time, the access network device #1 can achieve communication with the SF network element through the SC network element #1, and the access network device #2 can achieve communication with the SF network element through the SC network element #2.

[0156] Specifically, the implementation of the access network device #1 communicating with the SF network element through the SC network element #1, and the implementation of the access network device #2 communicating with the SF network element through the SC network element #2 can be referred to the related description of the above embodiments, which will not be repeated here.

[0157] Exemplarily, in the case that the SC network element is deployed in the access network device, in combination with the communication architecture shown in (b) of FIG. 2 and FIG. 3, the SC network element can be deployed in the access network device #1 and / or the access network device #2 in FIG. 2. Specifically, taking the example that the SC network element is deployed in the access network device #1 and the access network device #2 in FIG. 2, the communication architecture can be as shown in (b) of FIG. 4, at this time, the implementation of communication between each network element in (b) of FIG. 4 is similar to the implementation of communication between the corresponding network elements in (a) of FIG. 2 and FIG. 4, which can be referred to the related description of FIG. 2 above, which will not be repeated here.

[0158] Optionally, the access network device in the embodiments of the present application is a device for accessing a terminal device to a wireless network, which can be a node in a wireless access network, also can be called a base station, and also can be called a radio access network (RAN) node (or device). For example, the access network device can include an evolved Node B (Node B or eNB or e-NodeB, evolutional Node B) in an LTE system or an LTE-A system, such as a conventional macro base station eNB and a micro base station eNB in a heterogeneous network scenario. Alternatively, it can include a next generation Node B (gNB) of wideband code division multiple access (WCDMA). Alternatively, it can include a TRP, a home base station (for example, a home evolved Node B, or a home Node B, HNB), a baseband unit (BBU), a baseband pool (BBU pool), a base transceiver station (BTS) in a global system for mobile communication (GSM) or code division multiple access (CDMA) network, or a WiFi access point (AP), etc. Alternatively, it can include a base station in a non-terrestrial network (NTN), that is, it can be deployed on a high-altitude platform or a satellite, in the NTN, the access network device can be used as a layer 1 (L1) relay, or can be used as a base station, or can be used as a distributed unit (DU), or can be used as an integrated access and backhaul (IAB) node. Alternatively, the access network device can be a device implementing a base station function in IoT, such as V2X, D2D, or machine to machine (M2M), or can include a vehicle-mounted device or a wearable device, or can include an access network device in a 5G network or a public land mobile network (PLMN) evolved after 5G, and the embodiments of the present application are not limited.

[0159] Optionally, the base station in the embodiments of the present application can include various forms of base stations, such as macro base stations, micro base stations (also known as small stations), relay stations, access points, home base stations, TRPs, transmission points (TPs), mobile switching centers, etc., and the embodiments of the present application do not make specific limitations thereto.

[0160] In some possible scenarios, the access network device in the embodiments of the present application can also be a module or unit capable of implementing part of the functions of a base station, for example, the access network device can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be separately arranged or can be included in the same network element (such as a baseband unit (BBU)), that is, the BBU can include at least one CU and at least one DU. The RU can be included in a radio frequency device or a radio frequency unit; for example, included in a remote radio unit (RRU), an active antenna processing unit (AAU), or a remote radio head (RRH).

[0161] In different systems, the CU (or CU-CP and CU-UP), DU or RU can also have different names, but those skilled in the art can understand their meanings. For example, in an open radio access network (O-RAN or ORAN) system, the CU can also be referred to as an open (O)-CU, the DU can also be referred to as an O-DU, the CU-CP can also be referred to as an O-CU-CP, the CU-UP can also be referred to as an O-CU-UP, and the RU can also be referred to as an O-RU. For the convenience of description, the embodiments of the present application are described by taking the CU, the CU-CP, the CU-UP, the DU and the RU as examples. Any one of the CU (or CU-CP, CU-UP), the DU and the RU in the embodiments of the present application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0162] For example, in the ORAN system, the first network element and the second network element are both deployed in the access network device, which can be understood as: the first network element is an O-CU, and the second network element is an O-DU or an O-RU.

[0163] Referring to (a) in FIG. 5, a schematic diagram of another communication architecture provided by the embodiments of the present application is shown. As shown in (a) in FIG. 5, the CU and the DU are included in the same BBU, and the RU is included in the radio frequency unit. In addition, the access network device shown in (a) in FIG. 5 can communicate with the CN through a backhaul (BH) link, and the access network device can also communicate with the terminal device through the air interface. Specifically, the BBU in the access network device communicates with the CN through the BH link, and the RU in the access network device communicates with at least one terminal device through the air interface. The BBU can communicate with at least one RU through a fronthaul link, and the BBU and the RU can be co-located or can not be co-located.

[0164] Referring to (b) in FIG. 5, a schematic diagram of another communication architecture provided by the embodiments of the present application is shown. The communication system includes a RAN intelligent controller (RIC). The RIC includes a near-real time RIC (near-RT RIC) and a non-real time RIC (Non-RT RIC). The near-real time RIC is used for model training and inference. For example, the near-real time RIC is used for training an artificial intelligence (AI) model and performing inference using the AI model. The near-real time RIC can obtain network side and / or terminal side information from the access network device (for example, the CU, the CU-CP, the CU-UP, the DU, and / or the RU) and / or the terminal device. The information can be used as training data or inference data.

[0165] Optionally, the near-real time RIC can deliver the inference result to the access network device and / or the terminal device. Optionally, the inference result can be exchanged between the CU and the DU, and / or between the DU and the RU. For example, the near-real time RIC delivers the inference result to the DU, and the DU sends the inference result to the RU. The near-real time intelligent management of the RAN is implemented. Through data collection and related operations on the E2 interface, the near-real time control and optimization of the modules and resources of the O-RAN are implemented.

[0166] For example, the non-real time RIC is used for model training and inference. For example, the non-real time RIC is used for training an AI model and performing inference using the AI model. The non-real time RIC can obtain network side and / or terminal side information from the RAN node (for example, the CU, the CU-CP, the CU-UP, the DU, and / or the RU) and / or the terminal device. The information can be used as training data or inference data. The inference result can be delivered to the access network device and / or the terminal device. Optionally, the inference result can be exchanged between the CU and the DU, and / or between the DU and the RU. For example, the non-real time RIC delivers the inference result to the DU, and the DU sends the inference result to the RU.

[0167] Exemplarily, the near-real-time RIC and the non-real-time RIC can also be respectively set as a network element alone.

[0168] Optionally, the near-real-time RIC and the non-real-time RIC can also be part of other devices, for example, the near-real-time RIC is set in an access network device (for example, in a CU or a DU), and the non-real-time RIC is set in an operations and maintenance (OAM), a cloud server, a CN, or other access network devices.

[0169] Exemplarily, as shown in FIG. 6, an O-RAN central unit (O-CU) is used to implement a radio resource control (RRC) layer, a packet data convergence protocol (PDCP) layer, and a service data adaptation protocol (SDAP) layer and other control functions in the 3GPP standard.

[0170] An O-RAN central unit control plane (O-CU-CP) is used to implement functions of the RRC layer and control plane functions of the PDCP layer, similar to a CU-CP in the NR system. It belongs to the O-CU.

[0171] An O-RAN central unit user plane (O-CU-UP) is used to implement functions of the SDAP layer and user plane functions of the PDCP layer, similar to a CU-UP in the NR system. It belongs to the O-CU.

[0172] An O-RAN distributed unit (O-DU) is used to implement a radio link control (RLC) layer, a media access control (MAC) layer, and a higher physical layer (Higher PHY) based on low-layer function splitting. The higher physical layer functions include one or more of the following: forward error correction (FEC) encoding / decoding, scrambling / descrambling, or modulation / demodulation.

[0173] O-RAN radio unit (O-RU): based on low-layer function split, used to implement the lower physical layer (Lower PHY) function and radio frequency function in the 3GPP standard. Among them, the lower physical layer function includes one or more of the following: fast fourier transform (FFT) transform / inverse fast fourier transform (iFFT) transform, digital beamforming, or extraction and filtering of physical random access channel (PRACH), etc. Similar to TRP or RRH in 3GPP, but including low physical layer functions such as FFT / iFFT or PRACH extraction.

[0174] Optionally, the terminal device in the embodiments of the present application can be a user side device for implementing a wireless communication function, such as a terminal or a chip used in a terminal, etc. The terminal can be a user equipment (UE), an access terminal, a terminal unit, a terminal station, a mobile station (MS), a mobile station, a remote station, a remote terminal, a mobile device, a wireless communication device, a terminal agent or a terminal apparatus, etc. in a 5G network or a PLMN evolved after 5G. The access terminal can be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a smart phone, a personal digital assistant (PDA), a handheld device with a wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device or a wearable device, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self driving, a wireless terminal in telemedicine or telehealth services, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, a wireless data card, a tablet computer, a wireless modem, a handset, a laptop computer, a machine type communication (MTC) terminal, etc. Alternatively, the terminal can be a terminal with a communication function in IoT, such as a terminal in V2X (e.g. a vehicle networking device), a terminal in D2D communication, or a terminal in M2M communication, etc. The terminal can be mobile or fixed.

[0175] Optionally, the access network device and the terminal device, the access network device and the access network device, or the terminal device and the terminal device can communicate through a licensed spectrum, or can communicate through an unlicensed spectrum, or can simultaneously communicate through a licensed spectrum and an unlicensed spectrum.

[0176] Optionally, the access network device and the terminal device, the access network device and the access network device, or the terminal device and the terminal device can communicate through a frequency spectrum below 6 gigahertz (GHz), or can communicate through a frequency spectrum above 6 GHz, or can simultaneously use the frequency spectrum below 6 GHz and the frequency spectrum above 6 GHz. Embodiments of the present application do not limit the frequency spectrum resources used for wireless communication.

[0177] The sensing communication method provided by the embodiments of the present application will be described below with reference to the accompanying drawings. It can be understood that, in the embodiments of the present application, the first network element or the second network element can perform part or all of the steps in the embodiments of the present application, and these steps or operations are only examples, and the embodiments of the present application can also perform other operations or variations of various operations. In addition, each step can be performed in a different order according to the embodiments of the present application, and it is possible that not all operations in the embodiments of the present application are performed.

[0178] Referring to FIG. 7, it is a flowchart of a sensing communication method provided by the present application. The sensing communication method can include the following steps S701-S702:

[0179] S701, the first network element determines first indication information, the first indication information is used by the second network element to determine a first beam, the first beam is used to transmit a second sensing signal, wherein the first indication information indicates a first area, the first area is an area for sensing by the first network element, or the first indication information indicates first beam information.

[0180] For example, the beam can be embodied in the protocol as a spatial domain filter, or a spatial filter, or a spatial domain parameter, a spatial parameter, a spatial domain setting, a spatial setting, or quasi-colocation (QCL) information, a QCL assumption, a QCL indication, etc. The beam can be indicated by a transmission configuration indication (TCI) state parameter, or a spatial relation parameter. Therefore, in this application, the beam can be replaced by a spatial domain filter, a spatial filter, a spatial domain parameter, a spatial parameter, a spatial domain setting, a spatial setting, QCL information, a QCL assumption, a QCL indication, a TCI state, a spatial relation, etc. The above terms are also equivalent to each other. The beam in this application can also be replaced by other terms representing the beam, which is not limited in this application.

[0181] For example, the first beam used for transmitting the second sensing signal can be understood as: the beam corresponding to the radio signal resource associated with the second sensing signal is the first beam, or the second sensing signal can be carried by the first beam, or the transmission direction of the second sensing signal is the direction of the first beam, that is, the second network element can send the second sensing signal in the direction of the first beam.

[0182] For example, the first indication information can be implemented based on the following two cases:

[0183] Case one, the first indication information indicates the first area.

[0184] It should be understood that, unless otherwise specified, the first area in the embodiments of the present application refers to a geographical area.

[0185] For example, different sensing services can correspond to different sensing areas, so the first network element can set the first area according to the sensing service, that is, under different sensing services, the area (i.e. the first area) sensed by the first network element can be different.

[0186] For example, the sensing service can be the sensing service of the first network element itself, or the sensing service can come from a third network element. Specifically, in the case that the sensing service comes from the third network element, as shown in FIG. 8, before step S701, the sensing communication method can further include the following step S700:

[0187] S700, the third network element sends a sensing measurement request to the first network element, and correspondingly, the first network element receives the sensing measurement request from the third network element. The sensing measurement request is used to request the first network element to perform sensing.

[0188] For example, the sensing measurement request can indicate a sensing service; at this time, it can also be considered that the sensing measurement request enables the first network element to perform sensing through the sensing service.

[0189] Optionally, the sensing measurement request can indicate the size, position, etc. of the first area to directly indicate the first area; or the sensing measurement request can indicate a sensing service to indirectly indicate the first area through the sensing service; for example, the sensing service can be to sense one or more objects in the first area, or the sensing service can be to sense a specific object in the first area, and the embodiments of the present application are not limited thereto.

[0190] It can be understood that the sensing measurement request can also be referred to as other names, such as a sensing request, a sensing service request, a request information, etc., and the embodiments of the present application are not limited thereto. Any information that can be used by the first network element to determine the first area can be understood as the sensing measurement request.

[0191] Optionally, the first network element can determine the first indication information according to the shape of the first area. That is, the first indication information can indicate the first area through parameters capable of representing the shape of the first area.

[0192] As an example, the first area can be an elliptical area.

[0193] For example, in this example, the shape of the first area can be represented by the center position, the long semi-axis, and the short semi-axis; that is, the first indication information can indicate the center position of the first area (i.e. the center position of the first area), the length of the long semi-axis of the first area, and the length of the short semi-axis of the first area.

[0194] As another example, the first area can be a circular area.

[0195] For example, in this example, the shape of the first area can be represented by the center position and the radius; that is, the first indication information can indicate the center position of the first area (i.e. the center position of the first area) and the radius of the first area.

[0196] Alternatively, the shape of the first area can also be represented by the center position, the long semi-axis, and the short semi-axis, wherein the length of the long semi-axis is the same as the length of the short semi-axis; that is, the first indication information can indicate the center position of the first area (i.e. the center position of the first area), the length of the long semi-axis of the first area, and the length of the short semi-axis of the first area, and the length of the long semi-axis is the same as the length of the short semi-axis.

[0197] As a further example, the first region can be a sector region.

[0198] For example, the shape of the first region can be represented by a center position, a first position, and a deflection direction and angle of a first line segment, where the first line segment is a line segment connecting the center position and the first position. In this case, the first region is a region in a circle with the first line segment as a radius, and a line segment obtained by deflecting the first line segment and the first line segment enclose the first region.

[0199] As shown in (a) of FIG. 9, in the circle with the first line segment as a radius, the first line segment is deflected according to the deflection direction (i.e., right deflection) and the angle (i.e., deflection angle θ) of the first line segment, to obtain a first line segment'. Thus, in the circle with the first line segment as a radius, the sector region enclosed by the first line segment and the first line segment' is the first region.

[0200] Alternatively, the shape of the first region can be represented by a center position, a second position, and a third position. In this case, the first region is a region in a circle with a second line segment as a radius, and the second line segment and a third line segment enclose the first region, where the second line segment and the third line segment have the same length, the second line segment is a line segment connecting the center position and the second position, and the third line segment is a line segment connecting the center position and the third position.

[0201] As shown in (b) of FIG. 9, the second line segment and the third line segment are determined according to the second position and the third position, respectively. Further, the first region can be determined, that is, the sector region enclosed by the second line segment and the third line segment in the circle with the second line segment as a radius is the first region.

[0202] The above-mentioned FIG. 9 (i.e., (a) or (b) of FIG. 9) exemplarily lists the representation of the sector region. In fact, the sector region can also be represented by other parameters in addition to the above-mentioned parameters, such as a central angle, an arc length, and the like. The embodiments of the present application are not limited in this regard.

[0203] In addition, the above-mentioned three examples list the possible shapes of the first region. In fact, the first region can also have other shapes in addition to the above-mentioned shapes, such as a polygon, an irregular shape region, and the like. The embodiments of the present application are not limited in this regard. In this case, the implementation of the first indication information is similar to the implementation of the above-mentioned first indication information. For details, reference can be made to the above-mentioned related description, which will not be repeated here.

[0204] Case two, the first indication information indicates the first beam information.

[0205] Optionally, the first network element can determine the first beam information according to the first region, or in other words, determine the wireless resource information for transmitting the second reference signal. For example, the coverage range of the first beam determined according to the first beam information includes the first region, or the coverage range of the first beam partially overlaps with the first region.

[0206] For convenience of description, the shape of the first region is taken as an ellipse as an example in the following description, and the implementation of the first region in other shapes is similar to the implementation of the ellipse described below. For details, refer to the relevant description of the ellipse below, which is not described here again.

[0207] For example, the first beam information can include the following two implementations:

[0208] Implementation one: the first beam information can indicate the first direction, and the direction of the first beam is determined according to the first direction.

[0209] Optionally, the direction of the first beam can be the same as the first direction, or the direction of the first beam can be similar to the first direction, that is, the difference between the direction of the first beam and the first direction is less than or equal to a preset threshold.

[0210] Specifically, the preset threshold can be informed by the first network element to the second network element, or the preset threshold can be agreed by the first network element and the second network element in advance (such as agreeing on the preset threshold through a protocol), or the preset threshold can be a default between the first network element and the second network element.

[0211] Optionally, the first beam information can indicate the size of the first direction to directly indicate the first direction; for example, the first beam information can indicate 30°, and the first direction is 30° at this time. Alternatively, the first beam information can also indicate a parameter corresponding to the first direction, which indirectly indicates the first direction, and the embodiments of the present application are not limited thereto.

[0212] Optionally, the parameter corresponding to the first direction can be a first identifier, that is, the first beam information indirectly indicates the first direction by indicating the first identifier; that is, the first beam information indicating the first direction includes that the first beam information includes the first identifier.

[0213] As an example, the first identifier can be the index of a reference signal; at this time, the first direction is the direction of the beam corresponding to the reference signal.

[0214] For example, the reference signal includes but is not limited to SSB, channel status information reference signal (CSI-RS), and PRS. For convenience of description, the reference signal is taken as SSB as an example in the following description, and the implementation of the reference signal as other signals except SSB is similar to the implementation of SSB described below. For details, refer to the relevant description of SSB below, which is not described here again.

[0215] Based on the foregoing introduction of the SSB, each SSB corresponds to a beam, and therefore, the first indication information can indicate the index of the SSB, that is, the first identifier can be the index of the SSB, so that the second network element can determine a unique beam (that is, the beam corresponding to the SSB) based on the index of the SSB. The direction of the unique beam is the first direction.

[0216] As another example, the first identifier can be the identifier of the reference signal resource. At this time, the first direction is the direction of the beam corresponding to the reference signal resource. For example, the reference signal resource includes but is not limited to the PRS resource, the CSI-RS, and the SSB resource. For convenience of description, the following takes the PRS resource as an example for introduction, and the implementation of the reference signal resource other than the PRS resource is similar to the implementation of the PRS resource, and specific implementation can be referred to the foregoing description of the PRS resource and will not be repeated here.

[0217] Based on the foregoing introduction of the PRS resource, each PRS resource corresponds to a beam, and therefore, the first indication information can indicate the identifier of the PRS resource, that is, the first identifier can be the identifier of the PRS resource, so that the second network element can determine a unique beam (that is, the beam corresponding to the PRS resource) based on the identifier of the PRS resource. The direction of the unique beam is the first direction.

[0218] Implementation II: The first beam information can include the index of the first beam.

[0219] For example, in the case where the second network element has multiple beams, the first network element can select one beam from the multiple beams as the first beam, and indicate the index of the first beam through the first indication information.

[0220] Specifically, the first network element can select the first beam from the multiple beams according to the first area, for example, the first network element can select a beam whose coverage range overlaps with the first area from the multiple beams as the first beam. Alternatively, the first network element can select a beam whose coverage range has the largest overlap with the first area from the multiple beams as the first beam, and the present application does not limit this.

[0221] In order to indicate the index of the first beam, the first network element needs to obtain the beam information of the second network element, or the information of the resource used for sensing. The information can be configured through operation administration and maintenance (OAM), or the first network element requests the second network element to obtain.

[0222] S702, the first network element sends the first indication information to the second network element, and correspondingly, the second network element receives the first indication information from the first network element.

[0223] Optionally, after receiving the first indication information, the second network element can perform the following two operation steps:

[0224] In the first implementation, the second network element can determine whether to perform collaborative sensing with the first network element, and in a case where it is determined to perform collaborative sensing with the first network element, the second network element can determine the first beam according to the first indication information.

[0225] For example, the second network element performs collaborative sensing with the first network element, which can be understood as that the second network element performs sensing within the sensing area of the first network element (i.e., the first area); that is, the second network element participates in the sensing service performed by the first network element (i.e., performs sensing within the first area); or that the second network element assists the first network element in performing sensing. For convenience of description, the following describes the case where two devices perform collaborative sensing (i.e., the first network element and the second network element), and the same description applies here and will not be repeated here.

[0226] Optionally, the first network element can determine whether multiple devices need to perform collaborative sensing according to the sensing accuracy requirement; in a case where the sensing of the first network element on at least one object in the first area cannot meet the sensing accuracy requirement, it can be determined that multiple devices need to perform collaborative sensing.

[0227] For example, the sensing accuracy requirement can be predetermined (e.g., the sensing accuracy requirement is defined by a protocol). Alternatively, the sensing accuracy requirement can be informed to the first network element by the third network element, for example, the sensing measurement request can also indicate the sensing accuracy requirement, or the sensing accuracy requirement can be indicated by other information in addition to the sensing measurement request, which is not limited by the embodiments of the present application. Alternatively, the sensing accuracy requirement can be the default between the first network element and the third network element. For example, the second network element can determine whether the first network element performs collaborative sensing according to its remaining resources; for example, if the second network element has insufficient resources to support collaborative sensing with the first network element, the second network element can refuse to perform collaborative sensing with the first network element, and if the second network element has sufficient resources to support collaborative sensing with the first network element, the second network element can perform collaborative sensing with the first network element, and at this time, the second network element can determine the first beam according to the first indication information. For details, the implementation of the second network element to determine the first beam can refer to the related description of the second implementation below, which will not be repeated here.

[0228] Optionally, the second network element can feed back the determination result (i.e., whether to perform collaborative sensing with the first network element) to the first network element. For example, after step S702, the sensing communication method can further include the following step S703:

[0229] S703, the second network element sends feedback information to the first network element, and correspondingly, the first network element receives the feedback information from the second network element. The feedback information indicates whether the second network element performs cooperative sensing with the first network element.

[0230] For example, the feedback information can be represented by 1 bit. When the 1 bit is 1, it indicates that the second network element performs cooperative sensing with the first network element. When the 1 bit is 0, it indicates that the second network element refuses to perform cooperative sensing with the first network element. Alternatively, when the 1 bit is 0, it indicates that the second network element performs cooperative sensing with the first network element. When the 1 bit is 1, it indicates that the second network element refuses to perform cooperative sensing with the first network element.

[0231] Alternatively, the second network element can send acknowledgement (ACK) information to the first network element to indicate that the second network element performs cooperative sensing with the first network element. In this case, the feedback information is the ACK information. The second network element sends negative acknowledgement (NACK) information to the first network element to indicate that the second network element refuses to perform cooperative sensing with the first network element. In this case, the feedback information is the NACK information.

[0232] In addition, the second network element can also indicate whether the second network element performs cooperative sensing with the first network element by whether the feedback information is sent. For example, the second network element sends feedback information to the first network element, i.e., the second network element performs the above step S703, which indicates that the second network element refuses to perform cooperative sensing with the first network element. The second network element does not send feedback information to the first network element, i.e., the second network element does not perform the above step S703, which indicates that the second network element performs cooperative sensing with the first network element.

[0233] It can be understood that the feedback information can also be referred to as other names such as first information, response information, etc., which are not limited by the embodiments of the present application.

[0234] Based on the above optional scheme, the second network element can determine whether to perform cooperative sensing with the first network element according to the remaining resources of the second network element and feed back to the first network element, so that the first network element can know the device that performs cooperative sensing with it. For example, in the case that the second network element refuses to perform cooperative sensing with the first network element, the first network element can send first indication information to other network elements to find a device that can perform cooperative sensing with it, so as to ensure the sensing accuracy.

[0235] In the second implementation manner, the second network element can directly determine the first beam according to the first indication information. At this time, it is assumed that the second network element can perform cooperative sensing with the first network element.

[0236] Exemplarily, based on different implementations of the foregoing first indication information (i.e., the first indication information indicates the first area or the first beam information), the second network element determines that the implementation of the first beam is also different, and therefore, the second network element can determine the first beam based on the following two scenarios:

[0237] Scenario one, the first indication information indicates the first area.

[0238] Exemplarily, in scenario one, the second network element can determine the first beam according to the first area. For example, the second network element determines that the coverage range of the first beam can include the first area, or the coverage range of the first beam partially overlaps with the first area.

[0239] For the convenience of description, the implementation of the first beam is introduced below by taking the first area as an elliptical area. The implementation of the first beam in the case where the first area is an area of other shapes is similar to the implementation of the first beam in the case where the first area is an elliptical area, and can be specifically referred to the related description below, which is not described herein again.

[0240] Exemplarily, the second network element determines the first beam, and the coverage area of the first beam is the first area, or the coverage area of the first beam partially overlaps with the first area. Or, the second network element transmits a reference signal to the first area by configuring a wireless resource, and the coverage area of the reference signal is the first area, or the coverage area of the reference signal partially overlaps with the first area.

[0241] Alternatively, the second network element can also implement the foregoing process by using the configured reference signal resource, which is not limited by the embodiments of the present application.

[0242] Exemplarily, taking that the second network element performs sensing by using PRS as an example, in the case where the second network element transmits PRS by using multiple beams, the second network element can select one beam from the multiple beams as the first beam; for example, the second network element can select a beam whose coverage range partially overlaps with the first area from the multiple beams as the first beam; further, the second network element can select a beam whose coverage range has the largest overlap degree with the first area from the multiple beams as the first beam.

[0243] As shown in (a) of FIG. 10, the second network element transmits PRS by using 4 beams (i.e., beam #1 to beam #4), and the 4 beams correspond to 4 PRS resources (PRS #1 to PRS #4) respectively. By comparing the overlap degrees of the coverage ranges of the 4 beams with the first area respectively, it can be determined that the beam #2 has the largest overlap degree with the first area in the 4 beams; therefore, the beam #2 can be determined as the first beam, i.e., a reference signal is transmitted by using the resource corresponding to the PRS #2, so as to perform the sensing process.

[0244] Alternatively, the second network element can also achieve the above process by adjusting the beam corresponding to the configured reference signal resource. For example, in the case where the second network element is configured with multiple beams, the second network element can select any one of the multiple beams, or select a beam whose coverage area partially overlaps with the first area from the multiple beams, or select a beam whose coverage area has the largest overlap with the first area from the multiple beams; adjust the selected beam so that, compared with before the adjustment, the overlap between the coverage range of the adjusted beam and the first area is increased, or the coverage range of the adjusted beam overlaps with the first area, or the coverage range of the adjusted beam includes the first area. At this time, the adjusted beam is the first beam.

[0245] As shown in (b) of FIG. 10, taking the case where the overlap between the coverage range of the adjusted beam and the first area is increased as an example, in the case where the second network element is configured with four beams (i.e., beam #1 to beam #4), the second network element can adjust the direction of any one of the four beams, taking beam #2 as an example, so that the overlap between the coverage range of the adjusted beam #2 and the first area is increased. At this time, the adjusted beam #2 can be determined as the first beam.

[0246] Alternatively, in the case where the second network element is configured with one beam, if the coverage area of the one beam partially overlaps with the first area, or the coverage area of the one beam includes the first area, the second network element can directly determine the one beam as the first beam. Alternatively, in the case where the coverage area of the one beam partially overlaps with the first area, the second network element can also adjust the one beam and determine the adjusted beam as the first beam. For example, the implementation of the adjustment of the one beam by the second network element can refer to the related description of beam #2 shown in (b) of FIG. 10, which will not be repeated here.

[0247] If the coverage area of the one beam does not overlap with the first area, the second network element can also adjust the one beam and determine the adjusted beam as the first beam. Specifically, the implementation of the adjustment of the one beam by the second network element can refer to the related description of beam #2 shown in (b) of FIG. 10, which will not be repeated here.

[0248] Alternatively, in the case where the second network element is configured with one beam, the second network element does not need to judge whether the coverage area of the one beam partially overlaps with the first area, but directly adjusts the one beam and determines the adjusted beam as the first beam. Specifically, the implementation of the adjustment of the one beam by the second network element can refer to the related description of beam #2 shown in (b) of FIG. 10, which will not be repeated here.

[0249] Exemplarily, in the process of adjusting the beam by the second network element, the second network element can adjust the beam according to its own capability, so as to determine the first beam; for example, if the hardware capability of the second network element supports that the coverage area of the first beam includes the first area, the second network element can adjust the beam so that the coverage area of the first beam includes the first area; if the hardware capability of the second network element cannot support that the coverage area of the first beam includes the first area (that is, the second network element does not support the beam whose coverage area includes the first area), the second network element can adjust the beam so that the coverage area of the first beam partially overlaps with the first area, or, compared with before the adjustment, the degree of overlap between the coverage area of the first beam obtained after the adjustment and the first area is increased.

[0250] It can be understood that, in this application, “in the case of…” can also be expressed as “if…” or the like, and the meanings expressed are the same, so the three descriptions can be replaced with each other, and the embodiments of this application are not limited.

[0251] Based on scenario one, the first area is indicated by the first indication information from the first network element, and the first indication information is used by the second network element to determine the first beam; that is, the second network element can determine the first beam based on the first area from the first network element; since the first area is the area perceived by the first network element, the coverage range of the first beam determined by the second network element can partially overlap with the first area, or the coverage range of the first beam includes the first area, so that the second network element can also perceive in the first area, thereby improving the perception accuracy in the first area.

[0252] Scenario two, the first indication information indicates the first beam information.

[0253] Exemplarily, under scenario two, the second network element can determine the first beam according to the first beam information. Based on the foregoing, the first network element can determine the first beam information according to the first area, that is, the first beam information is related to the first area, so that the first beam determined by the second network element is also related to the first area. For example, the coverage range of the first beam determined according to the first beam information includes the first area, or the coverage range of the first beam partially overlaps with the first area.

[0254] In a possible implementation, in the case that the first beam information indicates the first direction, the second network element can determine the first beam according to the first direction; so that the direction of the first beam is the same as the first direction, or the direction of the first beam is close to the first direction.

[0255] As an example, in a case that the second network element is configured with multiple beams, or the second network element transmits PRS through multiple beams, the second network element can select one beam from the multiple beams as the first beam, for example, the second network element can select a beam with the same direction as the first direction from the multiple beams as the first beam, or the second network element can select a beam with the minimum difference between the direction and the first direction from the multiple beams as the first beam.

[0256] Similarly, in a case that the second network element is configured with one beam, or the second network element transmits PRS through one beam, if the direction of the one beam is the same as the first direction, or the direction of the one beam is different from the first direction and the difference between the direction of the one beam and the first direction is less than or equal to a preset threshold, the one beam can be taken as the first beam.

[0257] As another example, the second network element can adjust the beam configured (or used to transmit PRS) by the second network element according to the first direction to obtain the first beam, so that the direction of the first beam is the same as the first direction, or the direction of the first beam is close to the first direction.

[0258] For example, the direction of the first beam is close to the first direction, which can be understood as: the difference between the direction of the first beam and the first direction is less than or equal to a preset threshold, or the difference between the direction of the first beam and the first direction after adjustment is reduced compared to before adjustment.

[0259] Optionally, the second network element can adjust the beam according to the capability of the second network element to determine the first beam; for example, if the hardware capability of the second network element supports that the direction of the first beam is the same as the first direction, the second network element can adjust the beam so that the direction of the first beam is the first direction; if the hardware capability of the second network element cannot support that the direction of the first beam is the same as the first direction (that is, the second network element does not support the beam of the first direction), the second network element can adjust the beam so that the difference between the direction of the first beam and the first direction is less than or equal to a preset threshold, or the difference between the direction of the first beam and the first direction after adjustment is reduced compared to before adjustment.

[0260] As an example, in a case that the second network element is configured with multiple beams, or the second network element transmits PRS through multiple beams, the second network element can select any one beam from the multiple beams, or select a beam with the minimum difference between the direction and the first direction from the multiple beams; the selected beam is adjusted so that the difference between the direction of the adjusted beam and the first direction is reduced compared to before adjustment, or the direction of the adjusted beam is the same as the first direction. At this time, the adjusted beam is the first beam.

[0261] Or, in the case that the second network element is configured with one beam or the second network element transmits PRS through one beam, the second network element does not need to judge whether the difference between the direction of the one beam and the first direction is less than or equal to the preset threshold, directly adjusts the one beam, and determines the adjusted beam as the first beam.

[0262] As another example, in the case that the second network element is configured with multiple beams (or the second network element transmits PRS through multiple beams) and the first beam information includes the index of the first beam, the second network element directly determines the beam corresponding to the index as the first beam.

[0263] Based on scenario two, the second network element can determine the first beam based on the first beam information from the first network element; for example, the first network element can flexibly set the first beam information, for example, the coverage range of the beam corresponding to the first beam information includes the first area, at this time, the second network element can perform sensing in the first area through the first beam, thereby improving the sensing accuracy in the first area.

[0264] The sensing communication method provided by the embodiments of the present application can be used for the first network element to indicate the area (i.e. the first area) for sensing to the second network element, so that the second network element can determine the beam (i.e. the first beam) for transmitting the second sensing signal according to the first area. Or, the first network element can indicate the first beam information to the second network element, so that the second network element can determine the first beam according to the first beam information. For example, the first network element can set the first beam information according to the first area, at this time, the second network element determining the first beam according to the first beam information can also be understood as: the second network element determines the first beam according to the first area. For example, the coverage range of the first beam determined by the second network element can include the first area. Therefore, the second network element can perform sensing in the first area through the second sensing signal, that is, the first network element and the second network element can both perform sensing in the first area, that is, multiple network elements (such as the first network element and the second network element) can perform cooperative sensing in the first area; compared with the single-station sensing scheme, the sensing accuracy in the first area can be improved, and the sensing performance can be improved.

[0265] Optionally, after the above steps S702 or S703, the first network element can perform sensing in the first area. For example, after the above step S702, as shown in FIG. 11, the sensing communication method can further include the following steps S704-S706, that is, the first network element can perform sensing in the first area through steps S704-S706:

[0266] S704, the first network element transmits the first sensing signal through the second beam.

[0267] Exemplarily, the coverage of the second beam coincides with the first area, or the coverage of the second beam includes the first area.

[0268] Exemplarily, the first sensing signal is transmitted through the second beam, which can also be understood as that the first sensing signal is transmitted through the reference signal resource corresponding to the second beam; or it can also be understood as that the first sensing signal is transmitted in the direction of the second beam. In addition, since the coverage of the second beam includes the first area (or the coverage of the second beam coincides with the first area), it can be understood that the first sensing signal is transmitted to the target object in the first area. The target object can include at least one object in the first area.

[0269] S705, the first network element receives the echo signal of the first sensing signal.

[0270] Exemplarily, the echo signal of the first sensing signal represents the first sensing signal transmitted by the first network element, which is reflected and scattered by the target object in the propagation process and then received by the first network element.

[0271] S706, the first network element determines the first measurement information according to the echo signal of the first sensing signal. The first measurement information includes any one of the first measurement receiving signal result, the first spectrum information, the first point cloud information or the first object information. The first measurement receiving signal result is information obtained by measuring the echo signal of the first sensing signal, and the first spectrum information, the first point cloud information or the first object information is determined according to the first measurement receiving signal result.

[0272] Exemplarily, the measurement receiving signal result (such as the first measurement receiving signal result) can also be understood as the original signal information obtained by the receiver.

[0273] Optionally, the first measurement receiving information can include feature information of the echo signal of the first sensing signal. The feature information of the echo signal includes one or more of the signal strength, phase, angle of arrival and power of the echo signal.

[0274] Exemplarily, the first measurement receiving signal result can also be understood as the echo signal of the first sensing signal received by the first network element device; or it can also be understood as the sensing measurement result of the echo signal of the first sensing signal; therefore the first measurement receiving signal result can also be called the first measurement quantity or the first sensing measurement quantity; or the first measurement receiving signal result can also have other names other than the above, which is not limited by the embodiments of the application.

[0275] Optionally, the first spectrum information is obtained by performing a fast Fourier transform (FFT) on the received echo signal of the first sensing signal; that is, the first spectrum information is obtained by performing the FFT on the echo signal of the first sensing signal. For example, the first spectrum information can include one or more of distance, Doppler information, and velocity information.

[0276] Optionally, the point cloud refers to a set of points in space; thus, the point cloud indicated by the first point cloud information can be understood as a set of points sensed by the first network element in the first area. In addition, the information of the sensed point cloud refers to the features of the sensed point cloud; that is, the first point cloud information includes feature information of the point cloud. For example, the feature information of any point in the point cloud includes one or more of position information, Doppler information, velocity information, distance information, and angle information.

[0277] Optionally, the first object information can also be understood as information of at least one object sensed by the first network element in the first area. Therefore, the first object information can include feature information corresponding to each of the at least one object. The feature information of any object in the at least one object is determined by measuring the echo signal of the first sensing signal. For example, the feature information of the object can include one or more of position information, movement information, velocity information, size of the object, shape of the object, and motion trajectory of the object.

[0278] For example, the first object information can also be referred to as first target information, or the first object information can also be referred to as other names in addition to the above, which is not limited by the embodiments of the present application.

[0279] Optionally, the first measurement information can be any one of the result of the first measurement receiving signal, the first spectrum information, the first point cloud information, and the first object information, which can be determined by the first network element itself, such as randomly determining the parameters included in the first measurement information by the first network element; or the parameters included in the first measurement information can also be determined by the first network element according to the sensing measurement request, for example, the sensing measurement request can also indicate a fusion type, and the fusion type includes any one of signal fusion, spectrum fusion, point cloud fusion, or object fusion (or target fusion).

[0280] For example, when the fusion type includes signal fusion, the first measurement information includes the result of the first measurement receiving signal; when the fusion type includes point cloud fusion, the first measurement information includes the first point cloud information; when the fusion type includes spectrum fusion, the first measurement information includes the first spectrum information; and when the fusion type includes object fusion, the first measurement information includes the first object information.

[0281] It should be understood that the signal fusion refers to the fusion between the information at the signal level, i.e., the fusion between the results of the measurement received signals corresponding to the plurality of perception signals; for example, the plurality of perception signals can include a first perception signal, and correspondingly, the results of the measurement received signals corresponding to the plurality of perception signals can include a first result of the measurement received signal.

[0282] Similarly, the point cloud fusion refers to the fusion between the information at the point cloud level, i.e., the fusion between the point cloud information obtained by measuring the plurality of perception signals; for example, the plurality of perception signals can include a first perception signal, and correspondingly, the point cloud information corresponding to the plurality of perception signals can include first point cloud information. The spectrum fusion refers to the fusion between the spectrum information, i.e., the fusion between the spectrum information corresponding to the plurality of perception signals. The object fusion (or target fusion) refers to the fusion between the information at the object level (or target level), i.e., the fusion between the object information (or target information) corresponding to the plurality of perception signals; for example, the plurality of perception signals can include a first perception signal, and correspondingly, the point cloud information corresponding to the plurality of perception signals can include first object information (or first target information).

[0283] For example, the third network element can also indicate the fusion type through any information other than the perception measurement request, and in addition, the fusion type can also have other names, such as measurement information type, measurement result type, etc., which are not limited by the embodiments of the present application.

[0284] Optionally, based on the foregoing, the first network element and the second network element perform cooperative perception in the first area, and thus the second network element also performs perception in the first area. For example, the second network element can perform perception in the first area based on the following two ways:

[0285] For example, the second network element performs perception in the first area in a self-initiated and self-received manner.

[0286] For example, the implementation of the self-initiated and self-received manner can refer to the description of the related art above, which will not be described here.

[0287] For example, after the step S702, as shown in FIG. 12, the perception communication method can further include the following steps S707-S709:

[0288] S707, the second network element sends a second perception signal through a first beam.

[0289] For example, the implementation of the first beam can refer to the related description above, which will not be described here.

[0290] Exemplarily, the second sensing signal is transmitted through the first beam, which can also be understood as: the second sensing signal is transmitted / transmitted through the reference signal resource on the first beam; or, it can also be understood as: the second sensing signal is transmitted / transmitted in the direction of the first beam. In addition, since the coverage range of the first beam includes the first area (or the coverage range of the second beam coincides with the first area), or the coverage range of the first beam partially coincides with the first area, that is, the coverage range of the first beam can include at least one object (i.e. target object) in the first area, therefore, it can also be understood as: the second sensing signal is transmitted to the target object in the first area.

[0291] S708, the second network element receives the echo signal of the second sensing signal.

[0292] Exemplarily, the echo signal of the second sensing signal represents the second sensing signal transmitted by the second network element, which is reflected / scattered by the target object in the first area after propagation, and then received by the first network element / second network element.

[0293] S709, the second network element determines the second measurement information according to the echo signal of the second sensing signal. The second measurement information includes any one of the second measurement receiving signal result, the second spectrum information, the second point cloud information or the second object information, the second measurement receiving signal result is information obtained by measuring the echo signal of the second sensing signal, and the second spectrum information, the second point cloud information or the first object information is determined according to the second measurement receiving signal result.

[0294] Optionally, the implementation of the second measurement information is similar to the implementation of the above-mentioned first measurement information, and specific implementation can be referred to the above-mentioned related description of the first measurement object, which will not be repeated here.

[0295] Optionally, which type of the second measurement information is the second measurement receiving signal result, the second point cloud information, the second spectrum information or the second object information can be determined by the second network element itself, such as the second network element randomly determines the parameters included in the second measurement information; or, the parameters included in the second measurement information can also be determined according to the indication of the first network element.

[0296] Optionally, the second network element can determine the parameters included in the second measurement information according to the second indication information from the first network element. The second indication information indicates the fusion type, and the fusion type includes any one of signal fusion, point cloud fusion, spectrum fusion or object fusion (or target fusion). The fusion type includes signal fusion, and the second measurement information includes the second measurement receiving signal result; the fusion type includes point cloud fusion, and the second measurement information includes the second point cloud information; the fusion type includes spectrum fusion, and the second measurement information includes the second spectrum information; the fusion type includes object fusion, and the second measurement information includes the second object information.

[0297] For example, the implementation of signal fusion, point cloud fusion, spectrum fusion or object fusion (or target fusion) can refer to the related description of the above embodiments, which will not be repeated here.

[0298] Specifically, before step S709, the perception communication method can further include the following step S710 as shown in FIG. 13:

[0299] S710, the first network element sends second indication information to the second network element, and correspondingly, the second network element receives the second indication information from the first network element.

[0300] For example, the first indication information and the second indication information can also be carried in the same signaling, that is, the above step S701 and step S710 can be combined into one step; or the first indication information and the second indication information can be the same information, at this time, it can be considered that the first indication information also indicates the fusion type; that is, the first network element can not perform step S710, and the second network element can obtain the fusion type through step S701, so as to determine the second measurement information according to the fusion type.

[0301] For example, the second indication information can be determined by the first network element (such as randomly determined by the first network element); or it can also be determined by the first network element according to the indication of the third network element; specifically, the specific implementation of the first network element determining the second indication information according to the indication of the third network element can refer to the related description of the above step S706, which will not be repeated here.

[0302] Based on the optional scheme, the first network element can send the fusion type to the second network element, so that the second measurement information determined by the second network element meets the fusion requirements of the first network element (that is, the parameters included in the second measurement information are the same as the parameters included in the first measurement information), thereby facilitating fusion.

[0303] It should be understood that the order of steps S704-S706 and steps S707-S709 is not limited in the embodiments of the present application; for example, steps S704-S706 can be performed before steps S707-S709, or steps S704-S706 can be performed after steps S707-S709, or steps S704-S706 and steps S707-S709 can be performed simultaneously.

[0304] Alternatively, the execution sequence of step S704 and step S707 is not limited; for example, step S704 can be executed before step S707, or step S704 can be executed after step S707, or step S704 and step S707 can be executed simultaneously. Similarly, the execution sequence of step S705 and step S708 is not limited, and the execution sequence of step S706 and step S709 is not limited.

[0305] In some embodiments, after the second network element obtains the second measurement information, the second network element can inform the first network element of the second measurement information (i.e., the second network element sends the second measurement information to the first network element), and the first network element processes the second measurement information.

[0306] In a possible implementation, the first network element can fuse the first measurement information and the second measurement information to obtain third measurement information.

[0307] The third measurement information includes any one of a result of a third measurement received signal, third point cloud information, third spectrum information, or third object information, the result of the third measurement received signal is determined according to the result of the first measurement received signal and the result of the second measurement received signal; the third point cloud information is determined according to the first point cloud information and the second point cloud information; the third spectrum information is determined according to the first spectrum information and the second spectrum information, and the third object information is determined according to the first object information and the second object information.

[0308] For example, after step S709, as shown in FIG. 14, the perception communication method can further include steps S711-S712:

[0309] S711, the second network element sends the second measurement information to the first network element, and correspondingly, the first network element receives the second measurement information from the second network element.

[0310] S712, the first network element determines third measurement information according to the first measurement information and the second measurement information.

[0311] For example, based on different implementations of the first measurement information and the second measurement information, the third measurement information can include the following four implementations:

[0312] Implementation one: the third measurement information includes a result of a third measurement received signal, and the result of the third measurement received signal is determined according to the result of the first measurement received signal and the result of the second measurement received signal. As an example, the result of the third measurement received signal can be the superposition of the result of the first measurement received signal and the result of the second measurement received signal with different weights.

[0313] Exemplarily, the third measurement result of the received signal, the first measurement result of the received signal, and the second measurement result of the received signal can satisfy the following relationship (1): the third measurement result of the received signal = the first measurement result of the received signal * weight #1 + the second measurement result of the received signal * weight #2 (1)

[0314] wherein the weight #1 and the weight #2 are different in value.

[0315] Optionally, the weight #1 and the weight #2 can be determined by the first network element itself, for example, the weight #1 and the weight #2 are randomly determined by the first network element; or, the weight #1 and the weight #2 can be determined by the first network element according to the sensing accuracy requirement. For example, in the case that the weight #1 and the weight #2 are determined by the first network element itself, the weight #1 and the weight #2 can be any two values in 0-1.

[0316] Alternatively, the weight #1 and the weight #2 can be determined according to the overlapping ratio of the coverage area of the second beam and the first area and the overlapping ratio of the coverage area of the first beam and the first area.

[0317] For the convenience of description, the "overlapping ratio of the coverage area of the second beam and the first area" will be referred to as "first ratio" and the "overlapping ratio of the coverage area of the first beam and the first area" will be referred to as "second ratio" hereinafter. In other words, the weight #1 and the weight #2 are determined according to the first ratio and the second ratio.

[0318] Exemplarily, the overlapping ratio of the coverage area of the beam and the first area can be understood as the proportion of the overlapping part between the coverage area of the beam and the first area in the first area. That is, the first ratio is the proportion of the overlapping part between the coverage area of the second beam and the first area in the first area; and the second ratio is the proportion of the overlapping part between the coverage area of the first beam and the first area in the first area.

[0319] Exemplarily, the weight #1 and the weight #2 can be determined according to the size relationship between the first ratio and the second ratio. For example, in the case that the first ratio is greater than the second ratio, the value of the weight #1 is greater than the value of the weight #2; similarly, in the case that the first ratio is less than the second ratio, the value of the weight #1 is less than the value of the weight #2.

[0320] Alternatively, the value of the weight #1 can be equal to the first ratio, and the value of the weight #2 is equal to the second ratio. At this time, it can also be considered that the third measurement result of the received signal is determined according to the first ratio, the first measurement result of the received signal, the second ratio, and the second measurement result of the received signal. Further, the third measurement result of the received signal is the operation result of the first ratio, the first measurement result of the received signal, the second ratio, and the second measurement result of the received signal.

[0321] For example, the third measurement result of the received signal, the first proportion, the first measurement result of the received signal, the second proportion, and the second measurement result of the received signal can satisfy the following relationship (2), that is, the above relationship (1) can be replaced by the following relationship (2): the third measurement result of the received signal = the first measurement result of the received signal * the first proportion + the second measurement result of the received signal * the second proportion (2)

[0322] Optionally, the third measurement result of the received signal is determined according to the first proportion, the first measurement result of the received signal, the second proportion, and the second measurement result of the received signal, and includes that the third measurement result of the received signal is determined according to the first proportion, the first measurement result of the received signal, the second proportion, the second measurement result of the received signal, and the measurement result of the interference signal.

[0323] Optionally, the third measurement result of the received signal can be an operation result of the first proportion, the first measurement result of the received signal, the second proportion, the second measurement result of the received signal, and the measurement result of the interference signal. For example, the third measurement result of the received signal, the first proportion, the first measurement result of the received signal, the second proportion, and the second measurement result of the received signal can satisfy the following relationship (3), that is, the above relationship (2) can be replaced by the following relationship (3): the third measurement result of the received signal = the first measurement result of the received signal * the first proportion + the second measurement result of the received signal * the second proportion + the measurement result of the interference signal (3)

[0324] It should be understood that the above relationship (1) to relationship (3) exemplarily lists the implementation of the third measurement result of the received signal, and the first measurement result of the received signal and the second measurement result of the received signal can also obtain the third measurement result of the received signal through other operations in addition to the above operations, which is not limited by the embodiments of the present application. Optionally, since the first proportion is the overlapping proportion of the coverage area of the second beam and the first area, and the coverage area of the second beam and the first area are known to the first network element, the first network element can determine the first proportion according to the first area and the coverage area of the second beam.

[0325] Similarly, since the second proportion is the overlapping proportion of the coverage area of the first beam and the first area, and the first area is known to the first network element. In addition, in the case that the first indication information indicates the index of the first beam, or the direction of the first beam determined by the second network element is the first direction, the coverage area of the first beam is also known to the first network element. At this time, the first network element can determine the second proportion according to the coverage area of the first beam and the first area.

[0326] In a case that the direction of the first beam determined by the second network element is not the first direction (e.g., a difference between the direction of the first beam and the first direction is less than or equal to a preset threshold), the second network element can inform the first network element of the second proportion. For example, the second network element can indicate the second proportion to the first network element through the third indication information.

[0327] Exemplarily, after step S702, the perception communication method can further include step S713 as shown in FIG. 15:

[0328] S713, the second network element sends third indication information to the first network element, and correspondingly, the first network element receives the third indication information from the second network element.

[0329] Exemplarily, the third indication information can directly indicate the second proportion, for example, the third indication information can include the second proportion; or the third indication information can indicate the direction of the first beam or the coverage area of the first beam to indirectly indicate the second proportion.

[0330] Specifically, in a case that the third indication information indicates the direction of the first beam, the first network element can determine the coverage range of the first beam according to the direction of the first beam and the position of the second network element, and further determine the second proportion according to the first area and the coverage area of the first beam. In a case that the third indication information indicates the coverage range of the first beam, the first network element can directly determine the second proportion according to the first area and the coverage area of the first beam.

[0331] Exemplarily, the third indication information can be sent by the second network element to the first network element alone, that is, after step S702, the second network element sends the third indication information to the first network element. Alternatively, the third indication information can be sent to the first network element together with other information, for example, the third indication information can be carried in the same signaling as the second measurement information, in which case step S713 and step S711 can be considered as the same step. Similarly, the third indication information can be carried in the same signaling as the feedback information, in which case step S713 and step S703 can be considered as the same step, or the feedback information and the third indication information can be the same information, in which case the feedback information also indicates the second proportion, that is, the second network element can not perform step S713, and the first network element can obtain the second proportion in step S703.

[0332] As another example, the result of the third measurement of the received signal is a fitting of the result of the first measurement of the received signal and the result of the second measurement of the received signal.

[0333] Exemplarily, the fitting can be understood as a result obtained by aggregating multiple signal results, or a result obtained by deduplication processing of multiple signal results.

[0334] In a second implementation, the third measurement information includes third point cloud information, and the third point cloud information is determined according to the first point cloud information and the second point cloud information.

[0335] Optionally, the third point cloud information can be a superposition of the first point cloud information and the second point cloud information with different weights, or the third point cloud information can be a fitting of the first point cloud information and the second point cloud information.

[0336] For example, the third point cloud information can be obtained by a point cloud matching algorithm such as an iterative closest point (ICP) or an artificial intelligence (AI) related method, that is, the fusion of point clouds can be achieved by the ICP or the AI related method.

[0337] For example, the implementation of the third point cloud information is similar to the implementation of the third measurement receiving signal result in the first implementation, and details can be referred to the related description of the third measurement receiving signal result, which will not be described here.

[0338] In a third implementation, the third measurement information includes third spectrum information, and the third spectrum information is determined according to the first spectrum information and the second spectrum information.

[0339] Optionally, the third spectrum information can be a superposition of the first spectrum information and the second spectrum information with different weights, or the third spectrum information can be a fitting of the first spectrum information and the second spectrum information.

[0340] For example, the implementation of the third spectrum information is similar to the implementation of the third measurement receiving signal result in the first implementation, and details can be referred to the related description of the first implementation, which will not be described here.

[0341] In a fourth implementation, the third measurement information includes third object information, and the third object information is determined according to the first object information and the second object information.

[0342] Optionally, the third object information can be a superposition of the first object information and the second object information with different weights, or the third object information can be a fitting of the first object information and the second object information.

[0343] For example, the third object information can be obtained by a clustering algorithm such as a density-based spatial clustering of applications with noise (DBSCAN) or an AI-related method, that is, the clustering algorithm such as DBSCAN or the AI-related method can realize fusion of objects, for example, realize deduplication, fusion, etc. of object tracks.

[0344] For example, the implementation of the third object information is similar to the implementation of the result of the third measurement receiving signal in the above implementation mode one, and details can be referred to the related description in the above implementation mode one, which will not be described here.

[0345] Based on the above four implementation modes, the first network element can fuse the first measurement information and the second measurement information to obtain the third measurement information, so as to determine the perception result of the first area based on the third measurement information, which can improve the perception accuracy in the first area compared with the scheme of determining the perception result of the first area based on the first measurement information.

[0346] Optionally, after the first network element performs fusion (that is, the first network element determines the third measurement information), the first network element can send the third measurement information to the third network element, so that the third network element can determine the perception result of the first area based on the third measurement information.

[0347] For example, after step S712, as shown in FIG. 15, the perception communication method can further include the following step S714:

[0348] S714, the first network element sends the third measurement information to the third network element, and correspondingly, the third network element receives the third measurement information from the first network element.

[0349] Optionally, the first network element can send the third perception measurement information to the third network element within a perception period. For example, the perception period can be indicated by the third network element to the first network element. For example, the perception measurement request can indicate the perception period. Or the perception period can be indicated by other information besides the perception measurement request, which is not limited by the embodiments of the present application.

[0350] Specifically, the perception period can be represented by a first time length, or called a response time. For example, the first time length can be 10 milliseconds. At this time, the starting time of the perception period is defaulted as the time when the first network element receives the information carrying the first time length, that is, within 10 milliseconds after the first network element receives the information carrying the first time length, the first network element can send the third perception measurement information to the third network element.

[0351] Alternatively, the sensing period can be represented by a start time and an end time. At this time, after the first network element receives the information for carrying the sensing period, the first network element can send the third sensing measurement information to the third network element in the period from the start time to the end time.

[0352] Based on the possible implementation, after the first network element obtains the first measurement information and the second measurement information, the first network element can fuse the first measurement information and the second measurement information, and inform the third network element of the fused information (i.e., the third measurement information), which can improve the sensing accuracy in the first area compared to the sensing result of the first area determined based on the first measurement information. In addition, the resources of the third network element can be saved.

[0353] In another possible implementation, the first network element can directly send the first measurement information and the second measurement information to the third network element; and the third network element can process the first measurement information and the second measurement information, such as the third network element can fuse the first measurement information and the second measurement information to obtain the third measurement information.

[0354] For example, as shown in FIG. 16, the sensing communication method can further include the following steps S715-S716:

[0355] S715, the first network element sends the first measurement information to the third network element, and correspondingly, the third network element receives the first measurement information from the first network element.

[0356] S716, the first network element sends the second measurement information to the third network element, and correspondingly, the third network element receives the second measurement information from the first network element.

[0357] For example, the implementation of the second proportion can refer to the related description of the above implementation, which will not be repeated here.

[0358] For example, the step S715 can be executed before the step S716, or the step S715 can be executed after the step S716, or the step S715 can be executed simultaneously with the step S716, and the embodiments of the present application are not limited. It is only required to ensure that the step S715 is executed after the step S706, and the step S716 is executed after the step S709.

[0359] Optionally, the step S715 and the step S716 can be executed in the sensing period. Specifically, the implementation of the sensing period can refer to the related description above, which will not be repeated here.

[0360] Optionally, the third measurement information can be the superposition of the first measurement information and the second measurement information with different weights; or the third measurement information can be the fitting of the first measurement information and the second measurement information.

[0361] Optionally, the weight corresponding to the first measurement information (i.e., weight #1) and the weight corresponding to the second measurement information (i.e., weight #2) can be determined according to the first proportion and the second proportion.

[0362] For example, when the weight #1 and the weight #2 are determined according to the first proportion and the second proportion, the first network element can further indicate the first proportion to the third network element, and further, when the first network element can determine the second proportion (e.g., the first network element determines the second proportion by itself, or the second network element indicates the second proportion to the first network element (see the step S713 described above)), the first network element can further indicate the second proportion to the third network element. Alternatively, the first network element indicates the first proportion to the third network element, and the second network element indicates the second proportion to the third network element.

[0363] For example, the implementation of the first network element determining the first proportion and the second proportion can refer to the related description in the above possible implementation, which will not be repeated here.

[0364] Specifically, when the first network element indicates the first proportion to the third network element, the first measurement information and the first proportion can be carried in the same signaling, or the first measurement information can carry the first proportion, or the first measurement information and the first proportion can be carried in different signaling.

[0365] Similarly, when the first network element indicates the second proportion to the third network element, the second measurement information and the second proportion can be carried in the same signaling, or the second measurement information can carry the second proportion, or the second measurement information and the second proportion can be carried in different signaling, or the second network element can send the second proportion to the third network element through the first network element, which is not limited in the embodiments of the present application.

[0366] For example, the implementation of the information for carrying the first proportion and / or the information for carrying the second proportion is similar to the implementation of the third indication information described above, and can refer to the related description of the third indication information. In addition, the implementation of the third network element determining the third measurement information is similar to the implementation of the first network element determining the third measurement information in the above embodiments, and can refer to the related description of the above embodiments, which will not be repeated here.

[0367] Based on the possible implementation, after the third network element receives the first measurement information and the second measurement information, the third network element can fuse the first measurement information and the second measurement information to obtain fused information (i.e., the third measurement information), which can improve the perception accuracy in the first area compared to the perception result of the first area determined based on the first measurement information. In addition, since the third network element is a network element in the core network, the accuracy of the third measurement information determined by the third network element is higher than that of the third measurement information determined by the first network element.

[0368] The second network element adopts the self-transmitting and other-receiving mode to perform sensing in the first area.

[0369] For example, the implementation of the self-transmitting and other-receiving mode can refer to the description of the related art above, which will not be repeated here. The following describes an example in which the second sensing signal transmitted by the second network element is received by the first network element.

[0370] For example, after the step S702, the sensing communication method can further include the following steps S717-S719, as shown in FIG. 17.

[0371] S717, the second network element transmits the second sensing signal through the first beam.

[0372] For example, the step S717 is the same as the step S707, and details can refer to the description of the step S707 above, which will not be repeated here.

[0373] S718, the first network element receives the echo signal of the second sensing signal.

[0374] S719, the first network element determines the second measurement information according to the echo signal of the second sensing signal.

[0375] For example, the implementation of the second measurement information can refer to the description of the step S709 above, which will not be repeated here.

[0376] For example, the relationship between the steps S704-S706 and the steps S717-S719 is similar to the relationship between the steps S704-S706 and the steps S707-S709, and details can refer to the description above, which will not be repeated here.

[0377] Optionally, after the first network element obtains the first measurement information and the second measurement information, the first network element can process the first measurement information and the second measurement information. For example, the first network element can fuse the first measurement information and the second measurement information to obtain third measurement information, and further, the first network element can inform a third network element of the third measurement information, so that the third network element can determine a sensing result in the first area according to the third measurement information. Alternatively, the first network element can directly inform the third network element of the first measurement information and the second measurement information, and the third network element can determine the third measurement information according to the first measurement information and the second measurement information.

[0378] For example, the implementation of the first network element processing the first measurement information and the second measurement information can refer to the description of the first mode above, which will not be repeated here.

[0379] In addition to the sensing communication method shown above, the embodiments of the present application also provide a sensing communication method, which is determined by a third network element, a first area, and a device for cooperative sensing in the first area. The following describes the device for cooperative sensing in the first area determined by the third network element, taking the first network element and the second network element as examples. For example, as shown in FIG. 18, the sensing communication method includes the following steps:

[0380] S1801, the third network element determines fourth indication information and fifth indication information. The fourth indication information is used for the first network element to determine a second beam, and the second beam is used for transmitting a first sensing signal. The fifth indication information is used for the second network element to determine a first beam, and the first beam is used for transmitting a second sensing signal.

[0381] Optionally, the fourth indication information can indicate the first area, or the fourth indication information can indicate second beam information. For example, the implementation of the first area can refer to the related description in the above step S701, and details are not described herein again.

[0382] Optionally, the second beam information can indicate a second direction, and the direction of the second beam is determined according to the second direction; or the second beam information can include an index of the second beam. For example, the implementation of the second beam information is similar to the implementation of the first beam information in the above step S701, and details can refer to the related description of the above step S701, and details are not described herein again.

[0383] Optionally, the fifth indication information can indicate the first area or the first beam information. For example, the implementation of the fifth indication information is similar to the implementation of the first indication information in the above step S701, and details can refer to the related description of the above step S701, and details are not described herein again.

[0384] S1802A, the third network element sends the fourth indication information to the first network element, and correspondingly, the first network element receives the fourth indication information from the third network element.

[0385] Optionally, after receiving the fourth indication information, the first network element can determine the second beam according to the fourth indication information. For example, the implementation of the first network element to determine the second beam is similar to the implementation of the second network element to determine the first beam in the above step S702, and details can refer to the related description of the above step S702, and details are not described herein again.

[0386] S1802B, the third network element sends the fifth indication information to the second network element, and correspondingly, the second network element receives the fifth indication information from the third network element.

[0387] Optionally, after receiving the fifth indication information, the second network element can determine the first beam according to the fifth indication information. For example, the second network element determines the first beam according to the implementation of the step S702, which is described above and will not be repeated here.

[0388] After the step S1802A, the first network element can further perform the steps S1803-S1805:

[0389] S1803, the first network element transmits the first sensing signal through the second beam. The step S1803 is the same as the step S704 described above, which can be referred to for details and will not be repeated here.

[0390] S1804, the first network element receives the echo signal of the first sensing signal. The step S1804 is the same as the step S705 described above, which can be referred to for details and will not be repeated here.

[0391] S1805, the first network element determines the first measurement information according to the echo signal of the first sensing signal. The step S1805 is the same as the step S706 described above, which can be referred to for details and will not be repeated here.

[0392] For example, the first measurement information includes one of the first measurement result, the first point cloud information, the first spectrum information, or the first object information, which can be determined by the first network element itself, such as the first network element randomly determining the parameters included in the second measurement information; or the parameters included in the first measurement information can also be indicated by the third network element. For example, the third network element can indicate the fusion type through the indication information, and the fusion type includes any one of signal fusion, point cloud fusion, spectrum fusion, or object fusion (or target fusion).

[0393] For example, when the fusion type includes signal fusion, the first measurement information includes the first measurement result; when the fusion type includes point cloud fusion, the first measurement information includes the first point cloud information; when the fusion type includes spectrum fusion, the first measurement information includes the first spectrum information; and when the fusion type includes object fusion (or target fusion), the first measurement information includes the first object information.

[0394] For example, the indication information for indicating the fusion type and the fourth indication information can be carried in the same signaling, or the indication information for indicating the fusion type and the fourth indication information can be carried in different signaling, or the fourth indication information can carry the indication information for indicating the fusion type, that is, the fourth indication information can also indicate the fusion type.

[0395] For example, the implementation of the fusion type can be referred to the related description of the above embodiments, which will not be repeated here.

[0396] After step S1802B, the second network element can further perform step S1806:

[0397] S1806, the second network element sends the second sensing signal through the first beam. Wherein, step S1806 is the same as step S707, and details can be referred to the description of step S707, and details are not described herein.

[0398] The sensing communication method provided by the embodiment of the application, the third network element can send fourth indication information to the first network element and fifth indication information to the second network element, so that the first network element can determine the second beam for sensing in the first area, and the second network element can determine the first beam for sensing in the first area, so that the first network element and the second network element can perform sensing in the first area based on the second beam and the first beam respectively, that is, multiple network elements (such as the first network element and the second network element) can perform cooperative sensing in the first area. Compared with the single-station sensing scheme, the sensing accuracy in the first area can be improved, and the sensing performance can be improved.

[0399] Optionally, the second network element can perform sensing in the first area in a self-sending and self-receiving manner or a self-sending and other-receiving manner. For example, the implementation of the self-sending and self-receiving manner and the implementation of the self-sending and other-receiving manner can be referred to the related description of the above embodiment, and details are not described herein.

[0400] In a possible implementation form, the second network element performs sensing in the first area in a self-sending and self-receiving manner, that is, the second network element determines the sensing measurement information (that is, the second measurement information) corresponding to the second sensing signal in the first area.

[0401] For example, after step S1806, as shown in FIG. 19, the sensing communication method can further include steps S1807-S1808:

[0402] S1807, the second network element receives the echo signal of the second sensing signal. Wherein, step S1807 is the same as step S708, and details can be referred to the description of step S708, and details are not described herein.

[0403] S1808, the second network element determines the second measurement information according to the echo signal of the second sensing signal. Wherein, step S1808 is the same as step S709, and details can be referred to the description of step S709, and details are not described herein.

[0404] Optionally, the second measurement information includes which type of the following: a result of second measurement of a received signal, second point cloud information, second spectrum information, or second object information, which can be determined by the second network element itself, such as the second network element randomly determining the parameters included in the second measurement information; or the parameters included in the second measurement information can also be indicated by the third network element.

[0405] Optionally, the third network element can indicate the parameters included in the second measurement information through sixth indication information. The sixth indication information indicates a fusion type. For example, before step S1808, the perception communication method can further include the following step S1809, as shown in FIG. 20:

[0406] S1809. The third network element sends the sixth indication information to the second network element, and correspondingly, the second network element receives the sixth indication information from the third network element.

[0407] Optionally, the fifth indication information and the sixth indication information can be carried in the same signaling, or the fifth indication information and the sixth indication information can be carried in different signaling; or the sixth indication information can be carried in the fifth indication information, that is, the fifth indication information can also indicate the fusion type.

[0408] For example, the implementation of the sixth indication information is similar to the implementation of the second indication information in the above embodiment, and details can be referred to the related description of the second indication information, which will not be described here.

[0409] Optionally, after step S1808, the second network element can directly send the second measurement information to the third network element, or the second network element can send the second measurement information to the first network element, and the first network element processes the second measurement information; for example, the first network element can directly send the first measurement information and the second measurement information to the third network element; or the first network element can fuse the first measurement information and the second measurement information to obtain third measurement information, and further send the third measurement information to the third network element.

[0410] As an example, the second network element can directly send the second measurement information to the third network element, and similarly, the first network element can also directly send the first measurement information to the third network element. For example, as shown in FIG. 21, the perception communication method can further include the following steps S1810-S1811:

[0411] S1810. The first network element sends the first measurement information to the third network element, and correspondingly, the third network element receives the first measurement information from the first network element.

[0412] S1811. The second network element sends the second measurement information to the third network element, and correspondingly, the third network element receives the second measurement information from the second network element.

[0413] Exemplarily, the step S1810 can be performed before the step S1811, or the step S1810 can be performed after the step S1811, or the step S1810 can be performed simultaneously with the step S1811, and the embodiments of the present application do not make any limitation in this regard, as long as the step S1810 is performed after the step S1805 and the step S1811 is performed after the step S1808.

[0414] Optionally, after receiving the first measurement information and the second measurement information, the third network element can fuse the first measurement information and the second measurement information to obtain the third measurement information. Exemplarily, the implementation of the third measurement information can refer to the related description of the above embodiments, and details are not described herein again.

[0415] As another example, the second network element can send the second measurement information to the first network element, and further, the first network element can also send the first measurement information and the second measurement information to the third network element. Specifically, as shown in FIG. 22, the sensing communication method can further include the step S1810 and the following steps S1812-S1813:

[0416] S1812, the second network element sends the second measurement information to the first network element, and correspondingly, the first network element receives the second measurement information from the second network element. The step S1812 is the same as the step S711, and details can refer to the related description of the step S711, and details are not described herein again.

[0417] S1813, the first network element sends the second measurement information to the third network element, and correspondingly, the third network element receives the second measurement information from the first network element. The step S1813 is the same as the step S716, and details can refer to the related description of the step S716, and details are not described herein again.

[0418] Exemplarily, the step S1810 can be performed before the step S1813, or the step S1810 can be performed after the step S1813, or the step S1810 can be performed simultaneously with the step S1813, and the embodiments of the present application do not make any limitation in this regard.

[0419] As another example, the second network element can send the second measurement information to the first network element, the first network element can also fuse the first measurement information and the second measurement information to obtain the third measurement information, and further, the third network element can send the third measurement information to the third network element. Specifically, after the step S1805 and the step S1812, as shown in FIG. 23, the sensing communication method can further include the following steps S1814-S1815:

[0420] S1814, the first network element determines third measurement information according to the first measurement information and the second measurement information. The step S1814 is the same as the step S712, and details can be referred to the related description of the step S712, which will not be repeated here.

[0421] S1815, the first network element sends the third measurement information to the third network element. The step S1815 is the same as the step S714, and details can be referred to the related description of the step S714, which will not be repeated here.

[0422] In another possible implementation form, the second network element performs sensing in the first area in a self-healing manner, that is, the first network element determines sensing measurement information (that is, the second measurement information) corresponding to the second sensing signal in the first area.

[0423] For example, after the step S1806, as shown in FIG. 24, the sensing communication method can further include the following steps S1816-S1817:

[0424] S1816, the first network element receives the echo signal of the second sensing signal. The step S1816 is the same as the step S718, and details can be referred to the related description of the step S718, which will not be repeated here.

[0425] S1817, the first network element determines the second measurement information according to the echo signal of the second sensing signal. The step S1817 is the same as the step S719, and details can be referred to the related description of the step S719, which will not be repeated here.

[0426] Optionally, after the step S1817, the first network element can directly send the first measurement information and the second measurement information to the third network element, or the first network element can fuse the first measurement information and the second measurement information to obtain the third measurement information, and further send the third measurement information to the third network element.

[0427] Specifically, the processing of the first network element on the first measurement information and the second measurement information (such as directly sending the first measurement information and the second measurement information to the third network element, or fusing the first measurement information and the second measurement information to obtain the third measurement information, and further sending the third measurement information to the third network element) can refer to the related description of the above embodiments, which will not be repeated here.

[0428] In the sensing communication method described in the above embodiments, the first network element sends the first sensing signal and receives the echo signal of the first sensing signal as an example. Actually, the first network element can not send the first sensing signal, but only receive the echo signal of at least one sensing signal and / or at least one measurement information (the measurement information is determined according to the echo signal of the sensing signal).

[0429] For example, the first network element can receive the echo signal of the second sensing signal and the echo signal of the third sensing signal; the third sensing signal is a sensing signal sent by a fourth network element (to the target object); the fourth network element is configured to assist the first network element in sensing, and the fourth network element is different from the second network element.

[0430] Alternatively, the first network element can receive the echo signal of the second sensing signal and fourth measurement information; the fourth measurement information is determined according to the echo signal of the third sensing signal. Alternatively, the first network element can receive the second measurement information and the echo signal of the third sensing signal. Alternatively, the first network element can receive the second measurement information and the fourth measurement information.

[0431] Specifically, the implementation of the third sensing signal is similar to the implementation of the second sensing signal described above, the implementation of the fourth network element is similar to the implementation of the second network element described above, and the implementation of the fourth measurement information is similar to the implementation of the second measurement information described above. For details, refer to the related description above, which will not be repeated here.

[0432] Optionally, the first network element can process the two signals. Specifically, the processing of the echo signal of the sensing signal (such as the echo signal of the second sensing signal and / or the echo signal of the third sensing signal) by the first network element, and / or the processing of the measurement information (such as the second measurement information and / or the fourth measurement information) can be referred to the related description of the above embodiments, which will not be repeated here. It can be understood that the method and / or steps implemented by the first network element in each of the above embodiments can also be implemented by the components (such as processors, chips, chip systems, circuits, logic modules, or software) available for the first network element; the method and / or steps implemented by the second network element can also be implemented by the components (such as processors, chips, chip systems, circuits, logic modules, or software) available for the second network element; or the method and / or steps implemented by the third network element can also be implemented by the components (such as processors, chips, chip systems, circuits, logic modules, or software) available for the third network element. The chip system can be composed of a chip, or the chip system can include a chip and other discrete devices.

[0433] It should be noted that the communication apparatus includes hardware structure and / or software module corresponding to each function in order to realize the above functions.
