Description

Technical Field

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

[0002] Wireless communication can be a transmission communication between two or more communication devices using electromagnetic waves as a medium. Generally, the two or more communication devices include network devices and terminal devices, or the two or more communication devices include different terminal devices, or the two or more communication devices include different network devices.

[0003] Currently, in communication systems, taking the communication process between network devices and terminal devices as an example, a terminal device can report the communication capabilities it supports to the network device, so that the network device can know the communication capabilities supported by the terminal device and subsequently provide the terminal device with communication configurations that match the communication capabilities, so as to realize the data transmission of business data related to communication services.

[0004] However, future communication systems may provide sensing services in addition to communication services. For example, in sensing scenarios, future networks may connect to terminal devices of various forms and obtain the sensing or recognition results of different terminal devices on targets to improve sensing performance. In this case, since communication capabilities are not necessarily related to the device's ability to sense or recognize targets, the aforementioned interaction process targeting communication capabilities may no longer be applicable. Summary of the Invention

[0005] This application provides a communication method and related apparatus for recognizing sensing capabilities in a communication network, which is beneficial for the realization of sensing services.

[0006] The first aspect of this application provides a communication method applied to a first communication device. For example, the first communication device may be a communication equipment (such as a terminal device or network device), or it may be a component applied to a communication equipment (such as a processor, circuit, chip, or chip system responsible for communication functions), or it may be a logic module or software capable of implementing all or part of the functions of the communication equipment. The following description uses a first communication device as an example. In this method, the first communication device determines first information indicating its sensing capabilities. These sensing capabilities include one or more of the following: first capability information related to the measurement of sensing channel information; second capability information related to the acquisition of sensing target information; third capability information related to the fusion of the sensing target information; or fourth capability information related to the compression of the sensing target information. The first communication device then transmits the first information.

[0007] Based on the above scheme, after the first communication device sends the first information, the recipient of the first information can determine, based on the first information, that the sensing capability of the first communication device may include one or more of the above-mentioned capabilities. In this way, the recipient of the first information can identify, based on the first information, that the first communication device (or the communication equipment corresponding to the first communication device) possesses at least one of the following capabilities: the ability to measure sensing channel information, the ability to acquire sensing target information, the ability to fuse sensing target information, or the ability to compress sensing target information. This clarifies the first communication device's ability to sense targets, which is beneficial for the realization of sensing services.

[0008] As an example, if the first information at least indicates first capability information related to measurements of sensing channel information, it indicates that the first communication device supports measurements of one or more sensing channel information. Thus, the recipient of the first information can configure the channel measurement process of the first communication device based on the first capability information, thereby enabling the first communication device to provide measurement results of sensing channel information commensurate with its own capabilities, thereby enabling the implementation of sensing services.

[0009] And / or, the recipient of the first information can determine whether to configure the channel measurement process of the first communication device based on the first capability information. For example, the recipient can configure resources for the first communication device that has the channel measurement capability desired by the recipient, without configuring resources for the first communication device that does not have the channel measurement capability desired by the recipient. This can reduce resource overhead and enable the first communication device to perform channel measurement based on the measurement method desired by the recipient, thereby improving sensing performance.

[0010] As another example, if the first information at least indicates second capability information related to the acquisition of sensing target information, it indicates that the first communication device is capable of acquiring one or more types of sensing target information. Thus, the recipient of the first information can configure the first communication device's sensing target information acquisition process based on the second capability information, thereby enabling the first communication device to acquire sensing target information matching its own capabilities, thereby enabling the implementation of sensing services.

[0011] And / or, the recipient of the first information can determine whether to configure the acquisition process of the sensing target information of the first communication device based on the second capability information. For example, the recipient can configure resources for the first communication device that has the capability to acquire the sensing target information as desired by the recipient, without configuring resources for the first communication device that does not have the capability to acquire the sensing target information as desired by the recipient. This can reduce resource overhead and enable the first communication device to acquire the sensing target information in the way desired by the recipient, thereby improving sensing performance.

[0012] As another example, if the first information at least indicates third capability information associated with the fusion of perceived target information, it indicates that the first communication device supports one or more fusion methods for fusing perceived target information. Thus, the recipient of the first information can configure the fusion process of the first communication device's perceived target information based on the third capability information, thereby enabling the first communication device to provide fusion information matching its own capabilities to enable the implementation of sensing services.

[0013] And / or, the recipient of the first information can determine whether to configure the fusion process of the sensing target information of the first communication device based on the third capability information. For example, the recipient can configure resources for the first communication device that has the fusion capability of the sensing target information expected by the recipient, without configuring resources for the first communication device that does not have the fusion capability of the sensing target information expected by the recipient. This can reduce resource overhead and enable the first communication device to fuse the sensing target information based on the fusion method expected by the recipient, thereby improving sensing performance.

[0014] As another example, if the first information at least indicates fourth capability information related to the compression of the sensing target information, it indicates that the first communication device supports one or more compression methods for compressing the sensing target information. Therefore, the recipient of the first information can configure the compression process of the sensing target information of the first communication device based on the fourth capability information, thereby enabling the first communication device to provide compressed information matching its own capabilities to enable the implementation of sensing services.

[0015] And / or, the recipient of the first information can determine whether to configure the compression process of the sensing target information of the first communication device based on the fourth capability information. For example, the recipient can configure resources for the first communication device that has the compression capability of the sensing target information desired by the recipient, without configuring resources for the first communication device that does not have the compression capability of the sensing target information desired by the recipient. This can reduce resource overhead and enable the first communication device to compress the sensing target information based on the compression method desired by the recipient, thereby improving sensing performance.

[0016] Optionally, in this application, the sensing channel information can indicate the channel information involved in the sensing process, or the channel information involved in the sensing process; in other words, the sensing channel information can be used to implement sensing services or sensing services. For example, the sensing channel information can be used to reflect or indicate the channel characteristics experienced by the sensing signal (or sensing signal) transmitted on one or more channels. Such channel information may include one or more of the following: channel matrix, channel range-angle-velocity (RAV) spectrum, channel multipath information, channel frequency domain response, or channel spatial domain response. For example, sensing signals or communication signals can be transmissions on the 3GPP radio interface that can be used for sensing purposes; for example, this definition refers to new radio (NR) radio frequency signals, which in some cases can be extended by information created via previously specified functionalities in EPC and / or E-UTRAN.

[0017] Optionally, in this application, the sensing target (ST) can indicate a physical object or environmental feature detected, identified, or measured via wireless signals (such as radio frequency signals). For example, these sensing targets can be static (such as buildings, walls) or dynamic (such as vehicles, pedestrians). The aforementioned sensing channel information can be associated with the sensing target; for example, the sensing channel information is used to determine the sensing target.

[0018] Optionally, in this application, the perceived target information can indicate information such as the position, velocity, and shape of the perceived target inferred by the sensing technology through analysis of signal reflection, scattering, multipath, and other characteristics. The aforementioned sensing channel information and perceived target information can be correlated; for example, the sensing channel information is used to determine the perceived target information. The aforementioned perceived target and perceived target information can also be correlated; for example, the perceived target information is used to indicate relevant information about the perceived target, including one or more of the following: perceived target existence information, perceived target scattering point information, perceived target identification result, environmental information corresponding to the perceived target, or, the sensing type to which the perceived target belongs.

[0019] For example, after the transmitting device sends a sensing signal, the sensing signal, after being reflected, diffracted, or scattered by one or more sensing targets in physical space, reaches the receiving device. The receiving device can determine the sensing target information through the sensing channel information corresponding to the received signal, which indicates relevant information about the sensing target. For example, after the sensing signal is reflected, diffracted, scattered, or transmitted by the sensing target during transmission, the signal characteristics of the sensing signal will change. Therefore, the sensing channel information determined by the receiving device from the sensing signal received can be used to reflect these signal characteristics.

[0020] In one possible implementation of the first aspect, the first capability information indicates at least one of the following: the capability to measure the channel matrix, the capability to measure the channel RAV spectrum, the capability to measure the channel multipath information, the capability to measure the channel frequency domain response, or the capability to measure the channel spatial domain response.

[0021] Based on the above scheme, the measurement of communication channel information in traditional communication processes is generally associated with communication. This measurement capability of communication channel information is suitable for the communication process but has problems such as limited supported measurement content and limited feedback information. However, the first capability information associated with the measurement of sensing channel information can indicate at least one of the following: the measurement capability of the channel matrix, the measurement capability of the channel RAV spectrum, the measurement capability of the channel multipath information, the measurement capability of the channel frequency domain response, or the measurement capability of the channel spatial domain response. This enables the realization of sensing services through channel measurement capabilities suitable for the sensing process, thereby improving sensing performance.

[0022] Optionally, the communication metrics involved in the measurement of the aforementioned communication channel information include one or more of the following: reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), signal to interference plus noise ratio (SINR), or channel quality indicator (CQI).

[0024] Based on the above scheme, the second capability information associated with the acquisition of the perceived target information can indicate at least one of the above, so that the recipient of the first information can clearly know that the first communication device has the capability to acquire the perceived target information, which is beneficial to the acquisition of the perceived target information in the perception scenario.

[0030] In one possible implementation of the first aspect, the fourth capability information indicates at least one of the following: compression capability based on data dimension, compression capability based on geometric type, compression capability based on codebook, compression capability based on dictionary, or compression capability based on artificial intelligence (AI).

[0031] Based on the above scheme, the second capability information associated with the compression of the perceived target information can indicate at least one of the above, so that the receiver of the first information can clearly know that the first communication device has the capability to compress the perceived target information, which is beneficial to realize the compression of the perceived target information in the sensing scenario.

[0032] In one possible implementation of the first aspect, the method further includes: the first communication device receiving second information, the second information being used to query the sensing capability of the first communication device. Optionally, the query can be replaced by a request or an instruction to report, etc., and this application does not limit this.

[0039] Based on the above scheme, the second information may include at least one of the above to support querying a specified capability through the second information, so that the first communication device can provide capability information that meets the query requirements.

[0040] For example, when the second information includes the first indication information, it supports querying the measurement capabilities associated with the sensing channel information through the second information. Accordingly, the first communication device can determine and / or send capability information that satisfies the query based on the first indication information, that is, the first information may include first capability information, so that the recipient of the first information can determine the measurement capabilities of the first communication device associated with the sensing channel information based on the first capability information.

[0044] In one possible implementation of the first aspect, the method further includes: the first communication device receiving sensing measurement resource configuration information, the sensing measurement resource configuration information being determined based on the first information; and the first communication device performing measurements based on the sensing measurement resource configuration information.

[0045] Based on the above scheme, the recipient of the first information can provide sensing and measurement resource configuration information that matches the capabilities indicated by the first information, so that the first communication device can perform sensing and measurement based on the configuration information that matches its own capabilities, thereby improving sensing performance.

Another example is that the RU and DU of a base station can be deployed on a satellite, while the CU can be deployed on the ground. Similarly, core network equipment can also be deployed on satellites. For example, some core network user plane elements can be deployed on satellites to support direct interaction between terminals via satellite, eliminating the need for ground-based communication. Some core network control plane elements can also be deployed on satellites. For example, deploying mobility management and session management elements on satellites can support emergency disaster relief services in situations where there is no terrestrial network.

[0100] For example, network devices may be deployed on non-terrestrial platforms, including but not limited to low-Earth orbit satellites, medium-Earth orbit satellites, high-Earth orbit satellites, high-altitude platforms, drones, and other high-altitude platforms.

[0101] Optionally, RAN nodes can also be macro base stations, micro base stations, indoor stations, relay nodes, donor nodes, or radio controllers in cloud radio access network (CRAN) scenarios. RAN nodes can also be servers, wearable devices, vehicles, or in-vehicle equipment. For example, the access network equipment in V2X technology can be a roadside unit (RSU).

[0102] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, with different RAN nodes each implementing a portion of the base station's functions. For example, RAN nodes can be central units (CUs), distributed units (DUs), CU-control plane (CPs), CU-user plane (UPs), or radio units (RUs), etc. CUs and DUs can be set up separately or included in the same network element, such as a baseband unit (BBU). RUs can be included in radio frequency equipment or radio frequency units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs).

[0103] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an open access network (open RAN, O-RAN, or ORAN) system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software modules and hardware modules.

[0104] Communication between access network devices and terminal devices follows a specific protocol layer structure. This protocol layer may include a control plane protocol layer and a user plane protocol layer. The control plane protocol layer may include at least one of the following: radio resource control (RRC) layer, packet data convergence protocol (PDCP) layer, radio link control (RLC) layer, media access control (MAC) layer, or physical (PHY) layer, etc. The user plane protocol layer may include at least one of the following: service data adaptation protocol (SDAP) layer, PDCP layer, RLC layer, MAC layer, or physical layer, etc.

[0105] The correspondence between network elements and their achievable protocol layer functions in the ORAN system can be found in Table 1 below.

[0108] Network devices can be other devices that provide wireless communication functions for terminal devices. The embodiments of this application do not limit the specific technology or device form used in the network device. For ease of description, the embodiments of this application are not limited.

[0109] Network equipment may also include core network equipment, such as the Mobility Management Entity (MME), Home Subscriber Server (HSS), Serving Gateway (S-GW), Policy and Charging Rules Function (PCRF), and Public Data Network Gateway (PDN Gateway, P-GW) in 4th generation (4G) networks; and access and mobility management functions (AMF), user plane functions (UPF), or session management functions (SMF) in 5G networks. Furthermore, this core network equipment may also include other core network equipment in 5G networks and next-generation networks of 5G networks.

[0110] In this application embodiment, the device for implementing the function of the network device can be the network device itself, or it can be a device capable of supporting the network device in implementing that function, such as a chip system, which can be installed in the network device. In the technical solutions provided in this application embodiment, the example of a network device being used to implement the function of the network device is used to describe the technical solutions provided in this application embodiment.

[0111] (3) Configuration and Pre-configuration: In this application, both configuration and pre-configuration are used. Configuration refers to the network device sending configuration information or parameter values ​​of some parameters to the terminal device through messages or signaling, so that the terminal device can determine the communication parameters or resources during transmission based on these values ​​or information. Pre-configuration is similar to configuration; it can be parameter information or parameter values ​​that the network device and the terminal device have negotiated in advance, or it can be parameter information or parameter values ​​that the network device or the terminal device uses as specified by the standard protocol, or it can be parameter information or parameter values ​​that are pre-stored in the network device or the terminal device. This application does not limit this.

[0112] Furthermore, these values ​​and parameters can be changed or updated.

[0113] (4) The terms "system" and "network" in the embodiments of this application can be used interchangeably. "At least one" means one or more, and "more" means two or more. "And / or" describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, or B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the related objects before and after are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, "at least one of A, B and C" includes A, B, C, AB, AC, BC or ABC. And, unless otherwise specified, the ordinal numbers such as "first" and "second" mentioned in the embodiments of this application are used to distinguish multiple objects and are not used to limit the order, sequence, priority or importance of multiple objects.

[0114] (5) In the embodiments of this application, "send" and "receive" indicate the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX, which may include sending directly through the air interface or sending indirectly through the air interface by other units or modules. "Receive information from YY" can be understood as the source of the information being YY, which may include receiving directly from YY through the air interface or receiving indirectly from YY through the air interface by other units or modules. "Send" can also be understood as the "output" of the chip interface, and "receive" can also be understood as the "input" of the chip interface.

[0115] In other words, sending and receiving can occur between devices, such as between network devices and terminal devices, or within a device, such as between components, modules, chips, software modules, or hardware modules within the device via buses, wiring, or interfaces.

[0116] It is understandable that information may undergo necessary processing, such as encoding and modulation, between the source and destination, but the destination can understand the valid information from the source. Similar statements in this application can be interpreted in a similar way and will not be elaborated further.

[0117] (6) In the embodiments of this application, "instruction" may include direct instruction and indirect instruction, as well as explicit instruction and implicit instruction. The information indicated by a certain piece of information (as described below, the instruction information) is called the information to be instructed. In the specific implementation process, there are many ways to indicate the information to be instructed, such as, but not limited to, directly indicating the information to be instructed, such as the information to be instructed itself or its index. It can also indirectly indicate the information to be instructed by indicating other information, where there is an association between the other information and the information to be instructed; or it can only indicate a part of the information to be instructed, while the other parts of the information to be instructed are known or pre-agreed upon. For example, the instruction can be implemented by using a pre-agreed (e.g., protocol predefined) arrangement order of various information, thereby reducing the instruction overhead to a certain extent. This application does not limit the specific method of instruction. It is understood that for the sender of the instruction information, the instruction information can be used to indicate the information to be instructed, and for the receiver of the instruction information, the instruction information can be used to determine the information to be instructed.

[0118] In this application, unless otherwise specified, the same or similar parts between the various embodiments can be referred to each other. In the various embodiments of this application, and in the various implementation methods / methods / implementations within each embodiment, unless otherwise specified or logically conflicting, the terminology and / or descriptions between different embodiments and between the various implementation methods / methods / implementations within each embodiment are consistent and can be mutually referenced. The technical features in different embodiments and the various implementation methods / methods / implementations within each embodiment can be combined according to their inherent logical relationships to form new embodiments, implementation methods, methods, or implementation approaches. The embodiments described below do not constitute a limitation on the scope of protection of this application.

[0119] To facilitate understanding of the methods provided in the embodiments of this application, the system architecture of the methods provided in the embodiments of this application will be described below. It is understood that the system architecture described in the embodiments of this application is for the purpose of more clearly illustrating the solutions of the embodiments of this application and does not constitute a limitation on the solutions provided in the embodiments of this application.

[0120] Please see Figure 1a This is a schematic diagram of the architecture of the communication system 1000 used in an embodiment of this application. Figure 1a As shown, the communication system includes RAN 100 and core network 200. Optionally, the communication system 1000 may also include Internet 300. RAN 100 includes at least one RAN node (e.g., Figure 1a 110a and 110b, collectively referred to as 110, may also include at least one terminal (such as...). Figure 1aRAN 100, denoted as RAN 120a-120j, is collectively referred to as RAN 120. RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment. Figure 1a (Not shown in the image). Terminal 120 connects wirelessly to RAN node 110, and RAN node 110 connects wirelessly or via a wired connection to core network 200. The core network equipment in core network 200 and RAN node 110 in RAN 100 can be independent physical devices, or they can be the same physical device integrating the logical functions of core network equipment and RAN nodes. Terminals can connect to each other, and RAN nodes can connect to each other, via wired or wireless connections.

[0121] Figure 1b An example diagram of an O-RAN system is shown. An O-RAN system may include components other than those shown in the diagram. As illustrated, the access network device (RAN, such as an eNB, gNB, or next-generation access network device) communicates with the core network (CN) via a backhaul link and with the UE via an air interface.

[0122] In one possible implementation, this application can be applied to long-term evolution (LTE) wireless communication systems, NR wireless communication systems, and future new radio (NR) wireless communication systems. For example, this application can be applied to orthogonal frequency division multiplexing (OFDM) systems in LTE, OFDM systems in NR, future OFDM systems, and OFDM-like systems.

[0123] In wireless communication systems (e.g.) Figure 1a or Figure 1b In the system shown, taking the communication process between network devices and terminal devices as an example, the terminal device can report the communication capabilities it supports to the network device, so that the network device can know the communication capabilities supported by the terminal device and subsequently provide the terminal device with communication configurations that match the communication capabilities, so as to realize the data transmission of business related to communication services.

[0124] In future communication systems, in addition to providing communication services, sensing services may also be offered. This approach can be called wireless sensing fusion, and the resulting network can be understood as an integrated sensing and communication (ISAC) network. Wireless sensing fusion is one of the key technologies in communication network research and can be widely used in typical application scenarios such as intelligent transportation, intelligent low-altitude airspace, and intelligent networks. Communication sensing fusion achieves unified design of communication and sensing functions through signal joint design and hardware sharing. Sensing in communication sensing fusion can be understood as wireless sensing technology based on the communication system. For example, terminal devices or network devices transmit wireless signals to a target area or object and receive the echo signals reflected by the object. By analyzing the received signals, corresponding sensing measurements are obtained, such as the number, location, speed, and identification of the target object.

[0125] As an example, taking access network devices and / or terminal devices as sensing devices, sensing signals may be transmitted between access network devices and terminal devices, between terminal devices, and between access network devices. The following will combine... Figure 2 The process shown is illustrated using a vehicle as an example.

[0126] like Figure 2 As shown, the sensing signal can have the following six modes:

[0127] (a) The access network device sends a sensing signal, and the access network device receives the sensing signal.

[0128] (b) The terminal device sends a sensing signal, and the terminal device receives the sensing signal.

[0129] (c) One access network device sends a sensing signal, and another access network device receives the sensing signal.

[0130] (d) One terminal device sends a sensing signal, and another terminal device receives the sensing signal.

[0131] (e) The access network device sends a sensing signal, and the terminal device receives the sensing signal.

[0132] (f) The terminal device sends a sensing signal, and the access network device receives the sensing signal.

[0133] Optionally, (a) and (b) above can be understood as some implementation examples of mono-static sensing, and (c) to (f) can be understood as some implementation examples of bi-static sensing.

[0134] Future networks may connect to various sensing devices with different sensing capabilities (e.g., terminal devices or network devices). A single sensing device needs to acquire the sensing capabilities of other sensing devices and configure sensing measurements and result reporting based on their different capabilities. This allows for full utilization of the network's sensing capabilities for wide-area sensing and improved sensing performance. However, currently, there is no solution for acquiring the sensing capability information of these devices.

[0135] To address the aforementioned problems, this application provides a communication method and related apparatus, which will be described in detail below with reference to the accompanying drawings.

[0136] Please see Figure 3 This is a schematic diagram of an implementation of the communication method provided in this application, which includes the following steps.

[0137] It should be understood that in the following text, Figure 3 The method is illustrated by taking the first communication device and the second communication device as the execution subjects of the interaction, but this application does not limit the execution subjects of the interaction.

[0138] For example, the first communication device can be a first communication equipment, or a chip, baseband chip, modem chip, system-on-chip (SoC) chip containing a modem core, system-in-package (SIP) chip, communication module, chip system, processor, logic module, or software in the first communication equipment. The following explanation uses the first communication equipment as an example.

[0139] For example, the second communication device can be a second communication equipment, or a chip, baseband chip, modem chip, system-on-chip (SoC) chip containing a modem core, system-in-package (SIP) chip, communication module, chip system, processor, logic module, or software within the second communication equipment. The following explanation uses the second communication equipment as an example.

[0140] S301. The first communication device sends first information, and correspondingly, the second communication device receives the first information. The first information indicates the sensing capability of the first communication device, which includes one or more of the following: first capability information related to the measurement of sensing channel information; second capability information related to the acquisition of sensing target information; third capability information related to the fusion of the sensing target information; or fourth capability information related to the compression of the sensing target information.

[0141] Optionally, in this application, the sensing channel information can indicate the channel information involved in the sensing process, or the channel information involved in the sensing process; in other words, the sensing channel information can be used to implement sensing services or sensing services. For example, the sensing channel information can be used to reflect or indicate the channel characteristics experienced by the sensing signal (or sensing signal) transmitted on one or more channels. Such channel information may include one or more of the following: channel matrix, channel RAV spectrum, channel multipath information, channel frequency domain response, or channel spatial domain response.

[0142] Optionally, in this application, the sensing target (ST) can indicate a physical object or environmental feature detected, identified, or measured via wireless signals (such as radio frequency signals). For example, these sensing targets can be static (such as buildings, walls) or dynamic (such as vehicles, pedestrians). The aforementioned sensing channel information can be associated with the sensing target; for example, the sensing channel information is used to determine the sensing target.

[0143] Optionally, in this application, the perceived target information can indicate information such as the position, velocity, and shape of the perceived target inferred by the sensing technology through analysis of signal reflection, scattering, multipath, and other characteristics. The aforementioned sensing channel information and perceived target information can be correlated; for example, the sensing channel information is used to determine the perceived target information. The aforementioned perceived target and perceived target information can also be correlated; for example, the perceived target information is used to indicate relevant information about the perceived target, including one or more of the following: perceived target existence information, perceived target scattering point information, perceived target identification result, environmental information corresponding to the perceived target, or, the sensing type to which the perceived target belongs.

[0144] For example, after the transmitting device sends a sensing signal, the sensing signal, after being reflected, diffracted, scattered, or transmitted by one or more sensing targets in physical space, reaches the receiving device. The receiving device can determine the sensing target information through the sensing channel information corresponding to the received signal, which is used to indicate relevant information about the sensing target. For example, after the sensing signal passes through at least one of the sensing targets during transmission, such as reflection, diffraction, scattering, or transmission, the signal characteristics of the sensing signal will change. Therefore, the sensing channel information determined by the receiving device from the received sensing signal can be used to reflect these signal characteristics.

[0145] Optionally, the sensing capability indicated by the first information can be a sensing capability based on the 3rd Generation Partner Project (3GPP). This sensing capability can also be understood as: radio frequency (RF) sensing capability, non-RF sensing capability (such as radar signals, sonar signals, and other non-RF sensing-related capabilities), or radio frequency (RF) sensing capability. In other words, the first information can indicate that the first communication device possesses the capability to sense using sensing technologies defined by the 3GPP standard. For example, a communication device possessing the first capability information can be understood as having the capability to sense wireless network resources (e.g., time-domain resources, frequency-domain resources, spatial-domain resources, or code-domain resources) defined by the 3GPP standard and employing a sensing technology scheme defined by the 3GPP standard for sensing.

[0146] In this application, the communication device possesses a certain capability, which can be understood as the communication device supporting that capability.

[0147] It should be noted that the first information sent by the first communication device can indicate the capabilities of various devices, which will be described below with some examples.

[0148] As an example, the first information sent by the first communication device may indicate the capabilities of a terminal device, which may be a device possessing one or more perception-related capabilities (e.g., capabilities indicated by at least one of the following first capability information, second capability information, third capability information, or fourth capability information). There may be various relationships between the first communication device and the terminal device.

[0149] For example, the first communication device can be the terminal device or a module (such as a chip) of the terminal device, enabling the above solution to be applied to scenarios where the first communication device indicates the capabilities of the terminal device through first information. In this case, the first communication device can be the terminal device.

[0150] For example, the first communication device can be a device associated with the terminal device, including but not limited to an application server, an over-the-top (OTT) system host, an OTT virtual machine, an OTT server, or a cloud server. This allows the above solution to be applied to scenarios where the first communication device indicates the capabilities of one or more terminal devices in batches through capability information, thereby reducing overhead. In this case, the first communication device can be a device associated with the terminal device, such as a communication connection between the first communication device and the terminal device.

[0151] As another example, the first information sent by the first communication device can indicate the capabilities of a network device, which can be a network device (e.g., an access network device or a core network device) possessing one or more perception-related capabilities (e.g., capabilities indicated by at least one of the following first capability information, second capability information, third capability information, or fourth capability information). For example, the first communication device can be the network device or a module (e.g., a chip) of the network device, enabling the above scheme to be applied to scenarios where the first communication device indicates the capabilities of the network device through capability information. In this case, the first communication device can be the network device.

[0152] The following example, using the first communication device indicating its own capabilities through first information, will be used to illustrate various capability information.

[0153] As an example, the aforementioned first information may indicate that the first communication device possesses first capability information. Specifically, the first capability information relating to the measurement of sensing channel information can be understood as the first communication device possessing the capability to measure sensing channel information.

[0154] As another example, the aforementioned first information can indicate that the first communication device possesses second capability information. Wherein, the first communication device possessing second capability information related to the acquisition of sensing target information can be understood as the first communication device possessing the capability to acquire sensing channel information.

[0155] As another example, the aforementioned first information can indicate that the first communication device possesses third capability information. Wherein, the first communication device possessing third capability information related to the fusion of perceived target information can be understood as the first communication device possessing the ability to fuse perceived channel information.

[0156] As another example, the aforementioned first information may indicate that the first communication device possesses fourth capability information. Specifically, the first communication device possessing fourth capability information related to the compression of perceived target information can be understood as the first communication device having the capability to compress perceived channel information.

[0157] It should be noted that the first communication device can be a communication equipment (such as the aforementioned terminal equipment or network equipment), and correspondingly, the first communication device possessing certain capability information can be understood as the communication equipment possessing that capability information. Alternatively, the first communication device can be an internal module of a communication equipment (such as the aforementioned terminal equipment or network equipment) (e.g., a chip, baseband chip, modem chip, system-on-chip (SoC) chip containing a modem core, system-in-package (SIP) chip, communication module, chip system, processor, logic module, or software, etc.), and correspondingly, the first communication device possessing certain capability information can be understood as the communication equipment in which the first communication device is located possessing that capability information; and / or, the first communication device possessing certain capability information can be understood as the internal module of the communication equipment in which the first communication device is located possessing that capability information.

[0158] It should be noted that the second communication device can store, maintain, or manage the capabilities of one or more devices based on the first information received from one or more devices.

[0159] For example, the first communication device can be a terminal device, and the second communication device can be a network device, enabling the network device to store, maintain, or manage the capabilities of one or more terminal devices. For instance, if the second communication device is an access network device, the first communication device can transmit capability information via RRC messages, signaling / information / messages from the Physical Uplink Control Channel (PUCCH), signaling / information / messages from the Physical Uplink Shared Channel (PUSCH), or other signaling / information / messages defined by the network in the future. Similarly, if the second communication device is a core network device, the first communication device can transmit capability information via Non-Access Stratum (NAS) messages or other signaling / information / messages defined by the network in the future. Correspondingly, the first information described below can be transmitted in these ways; for example, the first information can be transmitted via RRC messages or other signaling / information / messages. In this case, the first communication device can be a terminal device, and the second communication device can be a network device.

[0160] For example, both the first and second communication devices mentioned above can be terminal devices, enabling one terminal device to store, maintain, or manage the capabilities of other terminal devices. For instance, the above scheme can be applied to sidelink scenarios, where the first and second communication devices can communicate via a proximity-based services communication 5 (PC5) interface or other interfaces defined by the future network. Correspondingly, the first information described later can be transmitted in these ways; for example, the first information can be transmitted via the PC5 interface or other interfaces. In this case, both the first and second communication devices mentioned above can be terminal devices.

[0161] For example, both the first and second communication devices described above can be network devices, enabling one network device to store, maintain, or manage the capabilities of other network devices. For instance, the first and second communication devices can transmit the first information via wired or wireless means. For example, the wireless means could be an Xn interface or other interfaces defined by the future network. Correspondingly, the second information described later can be transmitted via these means, such as through the Xn interface or other interfaces. In this case, both the first and second communication devices described above can be network devices.

[0162] based on Figure 3 In the illustrated scheme, after the first communication device sends the first information in step S301, the recipient of the first information can determine, based on the first information, that the sensing capability of the first communication device may include one or more of the aforementioned capabilities. In this way, the recipient of the first information can identify, based on the first information, that the first communication device (or the corresponding communication equipment) possesses at least one of the following capabilities: the ability to measure sensing channel information, the ability to acquire sensing target information, the ability to fuse sensing target information, or the ability to compress sensing target information. This clarifies the first communication device's ability to sense targets, which is beneficial for the implementation of sensing services.

[0163] The implementation of the above-mentioned capability information will be illustrated below.

[0164] Example 1: The first instruction information should at least indicate the first capability information.

[0165] In Example 1, if the first information at least indicates first capability information related to the measurement of sensing channel information, it indicates that the first communication device supports the measurement of one or more sensing channel information. Therefore, the recipient of the first information can configure the channel measurement process of the first communication device based on the first capability information, thereby enabling the first communication device to provide measurement results of sensing channel information matching its own capabilities, thus enabling the implementation of sensing services. And / or, the recipient of the first information can determine whether to configure the channel measurement process of the first communication device based on the first capability information. For example, the recipient can configure resources for a first communication device that possesses the sensing channel measurement capability desired by the recipient, without needing to configure resources for a first communication device that does not possess the desired sensing channel measurement capability. This reduces resource overhead while enabling the first communication device to perform sensing channel measurements based on the measurement method desired by the recipient, thereby improving sensing performance.

[0166] In one possible implementation, the first capability information indicates at least one of the following capabilities A through E:

[0167] Capability A. Channel matrix measurement capability.

[0168] As an example, the first capability information includes a field corresponding to capability A. This field can have a value of either 0 or 1, indicating whether the first communication device possesses capability A. For instance, a value of 1 indicates that the first communication device possesses capability A, and a value of 0 indicates that the first communication device does not possess capability A. Similarly, a value of 0 indicates that the first communication device possesses capability A, and a value of 1 indicates that the first communication device does not possess capability A.

[0169] As an example, the first capability information includes a field corresponding to capability A. Whether the value of this field is empty indicates whether the first communication device possesses capability A. For example, an empty value indicates that the first communication device does not possess capability A, and a non-empty value indicates that the first communication device possesses capability A. Alternatively, whether the value of this field is a default value indicates whether the first communication device possesses capability A. For example, a default value indicates that the first communication device possesses capability A, and a non-default value indicates that the first communication device does not possess capability A.

[0170] For example, when the first communication device has capability A, the first communication device has the ability to provide data corresponding to capability A. For instance, the data corresponding to capability A may be called channel matrix data (channelMatrixData) or another name defined by the future network. Taking channelMatrixData as an example, channelMatrixData may include one or more of the following:

[0171] TxId, RxId, SensingRSId, Time, or channelMatrixInfo;

[0172] Where TxId, RxId, SensingRSId, and Time represent the transmitter ID, receiver ID, sensing signal ID, and timestamp, respectively. channelMatrixInfo represents the channel matrix information.

[0173] Optionally, channelMatrixInfo includes one or more of the following:

[0174] channelMatrixInfoId, H Size-X H Size-Y , or channelMatrix;

[0175] Where channelMatrixInfoId is the identifier or index of the channel matrix information, H Size-X Let x be the x-dimensional dimension of the channel matrix H, corresponding to the number of transmit antennas (or antenna ports); H Size-Y y is the y-dimensional dimension of the channel matrix H, corresponding to the number of receiving antennas; channelMatrix is ​​an M×N (M and N are both positive integers) two-dimensional matrix, corresponding to the channel matrix H.

[0176] Capability B. Channel RAV profile measurement capability.

[0177] As an example, the first capability information includes a field corresponding to capability B. This field can have a value of either 0 or 1, indicating whether the first communication device possesses capability B. For instance, a value of 1 indicates that the first communication device possesses capability B, and a value of 0 indicates that the first communication device does not possess capability B. Similarly, a value of 0 indicates that the first communication device possesses capability B, and a value of 1 indicates that the first communication device does not possess capability B.

[0178] As an example, the first capability information includes a field corresponding to capability B. Whether this field is empty indicates whether the first communication device possesses capability B. For example, an empty value indicates that the first communication device does not possess capability B, and a non-empty value indicates that the first communication device possesses capability B. Alternatively, whether the field has a default value indicates whether the first communication device possesses capability B. For example, a default value indicates that the first communication device possesses capability B, and a non-default value indicates that the first communication device does not possess capability B.

[0179] Optionally, the first capability information includes a field corresponding to capability B. When the field indicates that the first communication device has capability B, the field may also indicate that the channel RAV spectrum measurement capability of the first communication device includes one or more of the following: distance power spectrum, angle power spectrum, Doppler power spectrum, distance-angle power spectrum, distance-Doppler power spectrum, angle-Doppler power spectrum, distance-angle-Doppler power spectrum, or other implementations defined by the future network.

[0180] For example, when the first communication device has capability B, the first communication device has the ability to provide data corresponding to capability B based on capability B. For example, the data corresponding to capability B may be called channel RAV profile data (channelRAVProfileData) or other names defined by the future network. Taking channelRAVProfileData as an example, channelRAVProfileData may include one or more of the following:

[0181] TxId, RxId, SensingRSId, Time, or channelRAVProfileData;

[0182] Where TxId, RxId, SensingRSId, and Time are the transmitter ID, receiver ID, sensing signal ID, and timestamp of the sensing signal, respectively, and channelRAVProfileData is the channel RAV spectrum data.

This field, while indicating that the first communication device possesses capability O, may also indicate that the first communication device supports compression capabilities for at least one of the following types of data: three-dimensional data, two-dimensional data, one-dimensional data, or other implementations defined by the future network. For example, the second capability information includes a field corresponding to capability O, and the field can have values ​​of 00, 01, 10, or 11. A value of 00 indicates that the first communication device does not possess capability O; a value of 01 indicates that the first communication device has compression capabilities based on one-dimensional data; a value of 10 indicates that the first communication device has compression capabilities based on two-dimensional data; and a value of 11 indicates that the first communication device has compression capabilities based on three-dimensional data.

[0284] Capability P. Compression capability based on geometry type (targetGeometryType-CompressionCapability).

[0285] As an example, the second capability information includes a field corresponding to capability P, which can have a value of either 0 or 1, used to indicate whether the first communication device possesses capability P. For example, a value of 1 indicates that the first communication device possesses capability P, and a value of 0 indicates that the first communication device does not possess capability P. Alternatively, a value of 0 indicates that the first communication device possesses capability P, and a value of 1 indicates that the first communication device does not possess capability P.

[0286] As an example, the first capability information includes a field corresponding to capability P. Whether the value of this field is empty indicates whether the first communication device possesses capability P. For example, an empty value indicates that the first communication device does not possess capability P, and a non-empty value indicates that the first communication device possesses capability P. Alternatively, whether the value of this field is a default value indicates whether the first communication device possesses capability P. For example, a default value indicates that the first communication device possesses capability P, and a non-default value indicates that the first communication device does not possess capability P.

[0287] Optionally, the first capability information includes a field corresponding to capability P. In addition to indicating that the first communication device has capability P, the field may also indicate that the first communication device supports compression capabilities for at least one of the following types of data: point cloud, line, polygon patch, cube type, or other implementations defined by the future network.

[0288] Capability Q. Codebook-based compression capability. For example, codebook-based compression can refer to first agreeing on / defining a codebook, finding the closest one or more codewords in the codebook for the data, and using these close codewords to represent the data.

[0289] As an example, the second capability information includes a field corresponding to capability Q, which can have a value of either 0 or 1, indicating whether the first communication device possesses capability Q. For example, a value of 1 indicates that the first communication device possesses capability Q, and a value of 0 indicates that the first communication device does not possess capability Q.

[0290] As an example, the first capability information includes a field corresponding to capability Q.

For example, an empty value indicates that the first communication device does not possess capability Q, and a non-empty value indicates that the first communication device possesses capability Q. Alternatively, whether the value of this field is a default value indicates whether the first communication device possesses capability Q. For example, a default value indicates that the first communication device possesses capability Q, and a non-default value indicates that the first communication device does not possess capability Q.

[0291] Capability R. Dictionary-Based Compression Capability. For example, dictionary-based compression can refer to performing dictionary transformations on data, and then further processing the result of the transformation. For instance, if the data to be compressed is X, the dictionary is matrix M, and the result of the dictionary transformation is Y = X * M, then Y is further compressed or processed (e.g., quantization).

[0292] As an example, the second capability information includes a field corresponding to capability R, which can have a value of either 0 or 1, indicating whether the first communication device possesses capability R. For example, a value of 1 indicates that the first communication device possesses capability R, and a value of 0 indicates that the first communication device does not possess capability R.

[0293] As an example, the first capability information includes a field corresponding to capability R. Whether the value of this field is empty indicates whether the first communication device has capability R. For example, an empty value indicates that the first communication device does not have capability R, and a non-empty value indicates that the first communication device has capability R. Alternatively, whether the value of this field is a default value indicates whether the first communication device has capability R. For example, a default value indicates that the first communication device has capability R, and a non-default value indicates that the first communication device does not have capability R.

[0294] Capability S: AI-based compression capability.

[0295] As an example, the second capability information includes a field corresponding to capability S, which can have a value of either 0 or 1, indicating whether the first communication device possesses capability S.

Alternatively, whether the value of this field is a default value indicates whether the first communication device possesses capability S. For example, a default value indicates that the first communication device possesses capability S, and a non-default value indicates that the first communication device does not possess capability S.

[0297] Alternatively, the fourth capability information can indicate other compression capabilities, such as discrete cosine transform (DCT), fast fourier transform (FFT), quantization compression, or other methods defined by the future network.

[0298] In one possible implementation, Figure 3 The method shown also includes:

[0299] S300. The second communication device sends second information, and correspondingly, the first communication device receives the second information. The second information is used to query the first information. Optionally, the query can be replaced by a request or an instruction to report, etc.

[0300] Therefore, the first communication device can also receive second information for querying the first information, and send the first information based on the second information, so that the first communication device can provide corresponding capability information based on the query of the second information.

[0301] For example, the second information includes at least one of the following:

[0302] The first indication information is used to query part or all of the first capability information, such as the first indication information being used to query one or more of the aforementioned capabilities A to E; or

[0303] The second instruction information is used to query part or all of the second capability information, such as the first instruction information being used to query one or more of the aforementioned capabilities F to J; or

[0304] The third instruction information is used to query part or all of the third capability information, such as the first instruction information being used to query one or more of the aforementioned capabilities K to N; or

[0305] The fourth instruction information is used to query part or all of the fourth capability information, such as the first instruction information which can be used to query one or more of the above capabilities O to S.

[0306] Therefore, the second information may include at least one of the above to support querying a specified capability through the second information, enabling the first communication device to provide capability information that meets the query requirements.

[0307] For example, when the second information includes the first indication information, it supports querying the measurement capabilities associated with the sensing channel information through the second information. Accordingly, the first communication device can determine and / or send capability information that satisfies the query based on the first indication information, that is, the first information may include first capability information, so that the recipient of the first information can determine the measurement capabilities of the first communication device associated with the sensing channel information based on the first capability information.

[0308] For example, when the second information includes second indication information, it supports querying the acquisition capability associated with the sensing target information through the second information. Accordingly, the first communication device can determine and / or send capability information that satisfies the query based on the second indication information, that is, the first information may include second capability information, so that the recipient of the first information can determine the acquisition capability of the first communication device associated with the sensing target information based on the second capability information.

[0309] For example, when the second information includes third indication information, it supports querying the fusion capability associated with the perceived target information through the second information. Accordingly, the first communication device can determine and / or send capability information that satisfies the query based on the third indication information, that is, the first information may include third capability information, so that the recipient of the first information can determine the fusion capability of the first communication device associated with the perceived target information based on the third capability information.

[0310] For example, if the second information includes fourth indication information, it supports querying the compression capability associated with the sensing target information through the second information. Accordingly, the first communication device can determine and / or send capability information that satisfies the query based on the fourth indication information, that is, the first information may include fourth capability information, so that the recipient of the first information can determine the compression capability of the first communication device associated with the sensing target information based on the fourth capability information.

[0311] As an example, the aforementioned first information may be UE Capability Information, or UE Capability Information contained in an RRC message, or information elements / signaling carried by an RRC message, or other information / signaling / messages defined by the network in the future for capability indication.

[0312] As an example, the aforementioned second information may be a UECapabilityEnquiry, or a UECapabilityEnquiry contained in an RRC message, or an information element / signaling carried by an RRC message, or other information / signaling / messages defined by the network in the future for capability querying.

[0313] In one possible implementation, Figure 3 The method further includes: the first communication device receiving sensing measurement resource configuration information, which is determined based on the first information; and the first communication device performing measurements based on the sensing measurement resource configuration information. Thus, the recipient of the first information can provide sensing measurement resource configuration information that matches the capabilities indicated by the first information, enabling the first communication device to perform sensing measurements based on configuration information that matches its own capabilities, thereby improving sensing performance.

[0314] For example, the sensing measurement resource configuration information may include measurement configuration information of the sensing signal, which may be used to configure one or more of the following: time-domain resources, frequency-domain resources, port resources, power information, quasi-co-located (QCL) information, or the time-domain behavior of the measurement (e.g., periodic, aperiodic, semi-continuous).

[0315] In one possible implementation, Figure 3 The method further includes: the first communication device receiving sensing reporting configuration information, which is determined based on the first information; and the first communication device sending sensing results based on the sensing reporting configuration. Thus, the recipient of the first information can provide sensing reporting configuration information that matches the capabilities indicated by the first information, enabling the first communication device to perform sensing reporting based on configuration information that matches its own capabilities, thereby improving sensing performance.

[0316] For example, the perception reporting configuration information may include the reporting configuration information of the perception results. This reporting configuration information may be used to configure one or more of the following for measurement and / or perception: the reporting amount, the reporting threshold of the reporting amount, the energy accumulation time length of the reporting result, the time domain behavior of the reporting (e.g., periodic, aperiodic, semi-persistent), or the carrying method of the reporting amount (e.g., core network data plane, core network control plane, access network data plane, or access network control plane).

[0317] As an example, the aforementioned reported quantity is used to determine the content and / or data format of the reported measurement. For example, the content of the measurement may include one or more of time delay, angle of arrival, angle of departure, Doppler, and perceived quality indication.

[0318] As an example, the reporting threshold mentioned above is a threshold used to determine whether to report a measurement.

[0319] As an example, the energy accumulation time length of the above-mentioned reporting results is used to determine the time length for data fusion of the reported measurements in the time domain.

[0320] As an example, in a sensing service, the sensing behavior of the first communication device mainly includes the following process: After the first communication device measures the sensing reference signal and obtains the measurement result, it processes the measurement result to generate the final reported quantity (i.e., the sensing result). The process of measuring the sensing reference signal can be configured based on the aforementioned sensing measurement resource configuration information, and the reported quantity can be configured based on the aforementioned sensing reporting configuration information.

[0321] The capability information indicated by the first information may affect these configuration information, thereby affecting the measurement and / or reporting process of the first communication device based on these configuration information. In other words, if the first information sent by the first communication device indicates that the first communication device has a certain capability (e.g., the value of a field corresponding to a certain capability information is 1), then the aforementioned sensing measurement resource configuration information and / or sensing reporting configuration information includes the configuration corresponding to that capability.

[0322] For example, if the first information indicates that the first communication device possesses capability G in the second capability information, and capability G indicates support for measuring {ScatterInfoId, nrofScatters, position}, then when the reporting quantity in the perception reporting configuration information is configured to include "targetScatterData", and "ScatterInfo" in "targetScatterData" is configured to include {ScatterInfoId, nrofScatters, position}, the first communication device will trigger the first communication device to report information such as ScatterInfoId, nrofScatters, and position after completing the measurement. For example, the behavior of the first communication device includes: measuring the reference signal, channel estimation, extracting delay and angle parameters, calculating the scattering point position, and generating the reporting quantity, which may include ScatterInfoId, nrofScatters, and position. It is understandable that, since the first information indicates that the first communication device possesses capability G in the second capability information, and capability G indicates support for measuring {ScatterInfoId, nrofScatters, position}, but the first information does not indicate that the first communication device supports or does not support measuring {Velocity(Doppler), power, SNR, likelihood, scatterType, positionAccuracy, or velocityAccuracy}, the reporting quantity in the perception reporting configuration information can be from "ScatterInfo" in "targetScatterData", excluding {Velocity(Doppler), power, SNR, likelihood, scatterType, positionAccuracy, or velocityAccuracy}. This ensures that the reporting quantity in the perception reporting configuration information provided by the second communication device will not exceed the capability of the first communication device, thus avoiding or reducing the occurrence of perception measurement failures.

[0323] For example, if the first information indicates that the first communication device possesses capability M in the third capability information, and the reporting quantity in the sensing reporting configuration information is configured to include "multi-SensingMode-Fusion", then after completing the measurement, the first communication device will trigger the first communication device to report the fusion result of the multi-sensing mode data. For instance, the behavior of the first communication device includes: measuring a reference signal, calculating the sensing result of the multiple modes, completing the fusion of the multi-mode sensing data, and generating a reporting quantity, which may include the fusion result of the multi-sensing mode data.

[0324] For example, if the first information indicates that the first communication device possesses capability O in the fourth capability information, and the reporting quantity in the perception reporting configuration information is configured to include "dataDimension-Compression" and "dataDimension-Compression" indicates compression of two-dimensional data, then after completing the measurement, the first communication device will trigger the first communication device to report the compression result of the two-dimensional data. For instance, the behavior of the first communication device includes: measuring a reference signal, calculating the perception result, transforming the dimension of the perception result into two-dimensional data, and generating a reporting quantity, i.e., the reporting quantity may include the compression result of the two-dimensional data.

[0325] Optionally, in Figure 3 In the method shown, the second communication device can obtain first information sent by one or more first communication devices and determine the capabilities of one or more first communication devices through one or more implementation processes. For example, the second communication device can store, maintain, or manage this capability information. Subsequently, the second communication device can use this capability information in various ways.

[0326] In method A, the second communication device can send configuration information based on capability information. This configuration information can be used to configure sensing measurements and / or sensing result reporting. Correspondingly, the first communication device can receive this configuration information and perform sensing measurements and / or sensing reporting based on it. The configuration information may include the aforementioned sensing measurement resource configuration information and / or sensing reporting configuration information. For details, please refer to the above implementation.

[0327] In Method B, the second communication device can receive a capability discovery request from another communication device, which may carry capability information desired by the other communication device. Subsequently, the second communication device can query capability information matching the capability discovery request from stored, maintained, or managed capability information, and send a capability discovery response to the other communication device. This response indicates one or more first communication devices possessing the desired capability information. In this way, the other communication device can establish a connection with the one or more first communication devices indicated by the capability discovery response to obtain sensing results provided by those one or more first communication devices, thereby improving sensing performance. Optionally, the other communication device can be a single first communication device or a different communication device than the first communication device; this is not limited here.

[0328] The following example, using the first communication device as the terminal device and the second communication device as the network device, illustrates the technical effects achieved by the above implementation process.

[0329] In some implementation processes, sensing capabilities such as sensing channel measurement capability, sensing target information acquisition capability, and sensing target information compression capability are defined for terminal devices. Detailed designs are provided for the implementation of each sensing capability, specifying its data format, content, and transmission scheme. Furthermore, the impact of sensing capabilities on subsequent measurement resource configuration, report configuration, terminal device measurement and behavior, and sensing reporting is defined, along with the protection procedures for physical layer measurements and transmission based on 3GPP sensing capabilities.

[0330] In some implementations, the ISAC network can establish agreements related to sensing capabilities with the terminal when providing sensing services. The network device can then successfully learn about the sensing capabilities of the terminal device, thereby enabling effective control over the subsequent sensing measurement configuration and sensing measurement behavior between the network and the terminal device.

In this embodiment, the connection may include various interfaces, transmission lines, or buses, etc., and this embodiment is not limited thereto. The antenna 715 is connected to the transceiver 713. The network interface 714 enables the communication device to communicate with other communication devices through a communication link. For example, the network interface 714 may include a network interface between the communication device and core network equipment, such as an S1 interface; the network interface may also include a network interface between the communication device and other communication devices (e.g., other network devices or core network equipment), such as an X2 or Xn interface.

Furthermore, the transmitter Tx in transceiver 713 is also used to receive modulated digital baseband signals or IF signals from processor 711, convert the modulated digital baseband signals or IF signals into RF signals, and transmit the RF signals through one or more antennas 715. Specifically, the receiver Rx can selectively perform one or more stages of downmixing and analog-to-digital conversion on the radio frequency signal to obtain a digital baseband signal or a digital intermediate frequency (IF) signal.
