[0099] The rapid advancement of wireless communication technology and the growing demand for high-quality data transmission are driving the development of advanced communication systems. One promising technology is ISAC, which has the potential to revolutionize various industries, including automotive, healthcare, and smart cities.

[0100] Perception technology uses radio frequency signals to obtain information about the characteristics of the environment and / or objects in the environment, such as shape, size, orientation, speed, position, distance between objects, or relative motion.

[0101] ISAC involves the simultaneous use of RF signals for both sensing and communication purposes. This integration can improve spectral efficiency, reduce latency, and enhance reliability in a variety of applications. ISAC is particularly relevant to mobile operators, UE vendors, automotive suppliers, and subscribers because it can significantly improve the overall user experience, increase network efficiency, and unlock new business opportunities.

[0102] ISAC enables the 3rd Generation Partnership Project (3GPP) network to evolve from a communication network to a communication-aware integrated network. By replicating the physical world through perception and exchanging information through communication, it connects the cyber and physical worlds and provides a key technical foundation for the fusion of the virtual and real worlds.

[0103] In some embodiments, the functional and performance requirements for ISAC services impacting buildings are studied. In this embodiment, perception applications such as intrusion detection, monitoring, navigation assistance, real-time map generation, and collision avoidance can be implemented using different perception methods via the fifth-generation mobile communication technology system (5GS) to meet the required perception accuracy. For example, intrusion detection applications can detect intrusions into restricted areas of highways, railways, unmanned aerial vehicles (UAVs), courtyards, and homes. Monitoring applications can monitor rainfall, travel, flooding, breathing, and movement. For commercial, vehicle-to-everything (V2X), public safety, and emergency service use cases, target objects and their environments can be supported with or without UEs, using licensed or unlicensed spectrum. This embodiment also defines service requirements for perception configuration, 5G wireless perception services, exposure, security, and charging.

[0104] In some embodiments, mobile operators can play an important role in providing 5GS-based ISAC to customers, including, for example, the management and control of 5G-based perception services, especially infrastructure-assisted environmental perception, infrastructure-based remote-operated driving, high-definition map collection and sharing, and remote-operated driving assistance.

[0105] In some embodiments, other use cases where 5GS is studied to provide communication-assisted awareness services include:

[0106] Real-time environmental monitoring: Utilizes wireless signals to reconstruct environmental maps, further improving positioning accuracy and enabling environmentally relevant applications. This includes a range of real-time monitoring applications, including dynamic 3D maps for assisted driving, pedestrian flow statistics, intrusion detection, and traffic detection.

[0107] Autonomous vehicles or UAVs: Autonomous vehicles or UAV applications share some common functional requirements. For example, they should support detect and avoid (DAA) to avoid obstacles. They should also be able to monitor path information, such as selecting a route and complying with traffic regulations.

[0108] Air pollution monitoring: The quality of the received wireless signal will show different attenuation characteristics with changes in air humidity, particulate matter (PM) concentration, carrier frequency, etc., and can be used for weather or air quality detection.

[0109] Indoor healthcare and intrusion detection. It can achieve respiratory rate estimation, respiratory depth estimation, apnea detection, elderly vital sign monitoring and indoor intrusion detection.

[0110] Due to limitations such as obstacles and sensing areas, the sensing signal cannot reach the sensing receiver, resulting in the inability of the sensing service to function normally.

[0111] Therefore, the present disclosure provides a method for performing perception services. When conditions are met, the perception transmitting end or the perception receiving end can determine to use the perception relay to perform the perception service to solve the limitations of obstacles and perception areas on the perception service and realize the execution of the perception service.

[0113] As shown in FIG1 , the communication system 100 includes a perception transmitter 101 , a perception relay 102 , and a perception receiver 103 .

[0114] In some embodiments, the communication system 100 may further include other devices, such as core network devices.

[0115] In some embodiments, the perception transmitting end 101 may be, for example, any one of a terminal, an access network device, and a wireless local area network access point (WLAN AP). The perception relay 102 may be a first perception relay controlled by the perception transmitting end, or a second perception relay controlled by the perception receiving end 103, and may be, for example, any one of a terminal, an access network device, and a WLAN AP.

[0125] This disclosure primarily uses a sensing transmitter controlling a first sensing relay to perform a sensing service between the sensing transmitter and the sensing receiver. However, it is understood that the sensing receiver controlling a second sensing relay to perform a sensing service between the sensing transmitter and the sensing receiver can refer to any embodiment of this disclosure and will not be elaborated upon in this disclosure.

[0126] FIG2 is an interactive diagram of a method for performing a perception service according to an embodiment of the present disclosure. As shown in FIG2 , an embodiment of the present disclosure relates to a method for performing a perception service, the method comprising:

[0127] In step S2101 , the perception receiving end 103 sends a perception service request to the perception transmitting end 101 .

[0128] In some embodiments, the sensing transmitting end 101 receives a sensing service request sent by the sensing receiving end 103. The sensing service request is used to request a sensing service.

[0129] In some embodiments, the sensing service request may include a first target sensing area and / or a first target quality of service. The first target quality of service is used to indicate a target quality of service for the sensing transmitter to perform the sensing service. The first target sensing area is used to indicate a target sensing area for the sensing transmitter to perform the sensing service.

[0130] In some embodiments, the sensing transmitting terminal may determine whether it is capable of performing the sensing service requested by the sensing service request based on the first target sensing area and / or the first target service quality. For example, if the sensing area of ​​the sensing transmitting terminal does not match the first target sensing area, it may be indicated that the sensing transmitting terminal may not be able to perform the sensing service requested by the sensing service request. For another example, if the sensing service performed by the sensing transmitting terminal cannot achieve the first target service quality, it may be considered that the sensing transmitting terminal may not be able to perform the sensing service requested by the sensing service request.

[0131] In step S2102 , the perception receiving end 103 sends the first information and / or the second information to the perception transmitting end 101 .

[0132] In some embodiments, the sensing transmitting end 101 receives the first information and / or the second information sent by the sensing receiving end 103 .

[0133] In some embodiments, the first information is used to indicate that the perception receiving end has not received the perception signal. That is, when the perception receiving end has not received the perception signal, the perception transmitting end may send the first information to the perception transmitting end to inform the perception transmitting end that it has not received the perception signal. For example, the perception receiving end may set a timer, and if the perception signal is not received within a preset time, the first information is sent to the perception transmitting end. Of course, the above-mentioned method of sending the first information is only an example, and the present disclosure is not limited thereto. If the perception receiving end does not receive the perception signal, it can be considered that the perception transmitting end may be unable to perform the perception service between the perception receiving end and the perception receiving end.

[0134] In some embodiments, the second information is used to indicate that the perception service performed by the perception transmitting end cannot reach the first target service quality. For example, the perception receiving end may not send the first target service quality to the perception transmitting end through the perception service request, but may determine by itself that the perception service performed by the perception transmitting end cannot reach the first target service quality, and send the second information to the perception transmitting end. However, it is understandable that the perception receiving end may also send the first target service quality to the perception transmitting end, and determine that the perception service performed by the perception transmitting end cannot reach the first target service quality, and send the second information to the perception transmitting end, which is not limited in the present disclosure. The perception service performed by the perception transmitting end cannot reach the first target service quality, that is, the perception transmitting end does not have the ability to reach the first target service quality, or it can also be said that the perception transmitting end does not meet the first target service quality.

[0135] In some embodiments, upon receiving the first information, the perception transmitting end may determine to use the perception relay to perform a perception service between the perception transmitting end and the perception receiving end. Upon receiving the second information, the perception transmitting end may determine to use the perception relay to perform a perception service between the perception transmitting end and the perception receiving end. The perception transmitting end may also receive the first information and the second information and determine to use the perception relay to perform a perception service between the perception transmitting end and the perception receiving end.

[0136] In some embodiments, the names of the first information and the second information are not limited. For example, the first information may be "indication information," but is not limited thereto. The second information may be "indication information," but is not limited thereto.

[0137] In some embodiments, the perception receiving end may send the first information and / or the second information to the perception transmitting end through a core network device. The core network device is used to establish communication between the perception transmitting end and the perception receiving end. For example, when a direct communication path exists between the perception transmitting end and the perception receiving end, the perception transmitting end and the perception receiving end may communicate directly. When no communication path exists between the perception transmitting end and the perception receiving end, communication between the perception transmitting end and the perception receiving end may be established through the core network device. For example, the perception receiving end may send an instruction to the core network device, instructing the core network device to send the first information and / or the second information to the perception transmitting end.

[0138] In some embodiments, when the first information and / or the second information is sent through the core network device and the transmitting end is perceived as a terminal, the first information and / or the second information may be received from the access and mobility management function (AMF) and received through the N1 node. Of course, this is only an exemplary case, and the first information and / or the second information may also be received through other nodes, which is not limited in this disclosure.

[0139] In step S2103 , the perception transmitting end 101 determines that the first condition is met, and uses the perception relay 102 to perform a perception service between the perception transmitting end 101 and the perception receiving end 103 .

[0140] In some embodiments, when a first condition is met, the sensing transmitter 101 can use the sensing relay 102 to perform a sensing service between the sensing transmitter 101 and the sensing receiver 103. In this disclosure, a sensing relay controlled by the sensing transmitter is referred to as a first sensing relay. For example, the sensing transmitter sends a sensing signal to the first sensing relay and controls the first sensing relay to forward the sensing signal to the sensing receiver. The sensing relay 102 can be a sensing relay controlled by the sensing receiver, and in this disclosure, a sensing relay controlled by the sensing receiver is referred to as a second sensing relay. The sensing receiver can control the second sensing relay to receive the sensing signal sent by the sensing transmitter, and the sensing receiver can then receive the sensing signal from the second sensing relay.

[0141] In some embodiments, satisfying the first condition includes at least one of the following: the perception transmitting end determines that the perception area of ​​the perception transmitting end does not match the first target perception area, and the first target perception area is used to indicate the target perception area for the perception transmitting end to perform the perception service; the perception transmitting end determines that the perception service performed by the perception transmitting end cannot reach the first target service quality, and the first target service quality is used to indicate the target service quality of the perception service performed by the perception transmitting end; the perception transmitting end receives first information sent by other devices, and the first information is used to indicate that the perception receiving end has not received the perception signal; the perception transmitting end receives second information sent by other devices, and the second information is used to indicate that the perception transmitting end cannot meet the first target service quality; it is determined that there is a first perception relay that meets the second condition; and authorization is obtained to use the first perception relay to perform the perception service.

[0142] Optionally, satisfying the first condition may include the sensing transmitting terminal determining that the sensing transmitting terminal's sensing area does not match a first target sensing area. That is, the sensing transmitting terminal may determine that the sensing transmitting terminal's sensing area does not match the first target sensing area. The first target sensing area may be sent by the sensing receiving terminal or a core network device based on a sensing service request. That is, the sensing receiving terminal or the core network device indicates the target sensing area when requesting the sensing service. For example, the sensing transmitting terminal may receive the sensing service request sent by the sensing receiving terminal in step S2101 and obtain the first target sensing area therefrom. For another example, the sensing transmitting terminal may receive the sensing service request sent by the core network device and obtain the first target sensing area therefrom. It is understood that step S2101 is optional. The first target sensing area indicates the target sensing area for the sensing transmitting terminal to perform the sensing service requested by the sensing service request. When the sensing transmitting terminal's sensing area does not match the first target sensing area, it may be considered that the sensing transmitting terminal may be unable to perform the sensing service between the sensing transmitting terminal and the sensing receiving terminal, or that the sensing transmitting terminal may be performing the sensing service between the sensing transmitting terminal and the sensing receiving terminal poorly. Therefore, when this condition is met, the sensing transmitter can determine to use the sensing relay to perform the sensing service between the sensing transmitter and the sensing receiver. For example, although the sensing transmitter cannot send the sensing signal to the sensing receiver within the sensing area, it can send it to the sensing relay, which will then forward it to the sensing receiver.

[0143] Optionally, satisfying the first condition may include the sensing transmitting terminal determining that the sensing service performed by the sensing transmitting terminal cannot achieve a first target quality of service. That is, the sensing transmitting terminal may determine that the sensing service performed by the sensing transmitting terminal cannot achieve the first target quality of service. The first target quality of service may be sent by the sensing receiving terminal or the core network device based on the sensing service request. That is, the sensing receiving terminal or the core network device indicates the target quality of service when requesting the sensing service. For example, the sensing transmitting terminal may receive the sensing service request sent by the sensing receiving terminal in step S2101 and obtain the first target quality of service therefrom. It is understandable that step S2101 is optional. The first target quality of service indicates the target quality of service for the sensing service requested by the sensing transmitting terminal when performing the sensing service. If the sensing transmitting terminal is unable to achieve the first target quality of service, that is, if the sensing transmitting terminal determines that it cannot achieve the first target quality of service when performing the sensing service, it may be considered that the sensing transmitting terminal may be unable to perform the sensing service between the sensing transmitting terminal and the sensing receiving terminal, or it may be considered that the sensing transmitting terminal performs the sensing service between the sensing transmitting terminal and the sensing receiving terminal poorly. Therefore, when this condition is met, the perception transmitting end may determine to use the perception relay to perform the perception service between the perception transmitting end and the perception receiving end.

[0144] Optionally, satisfying the first condition may include the perception transmitting end receiving first information sent by the perception receiving end. That is, the perception transmitting end may receive the first information sent by the perception receiving end. The first information is used to indicate that the perception receiving end has not received the perception signal. It is understandable that if the perception receiving end does not receive the perception signal, it can be considered that the perception transmitting end may not be able to perform the perception service between the perception transmitting end and the perception receiving end. Therefore, when this condition is met, the perception transmitting end may determine to use the perception relay to perform the perception service between the perception transmitting end and the perception receiving end. Alternatively, satisfying the first condition may include the perception transmitting end receiving the first information sent by the core network device. That is, the perception receiving end may send the first information via the core network device.

[0145] Optionally, satisfying the first condition may include the perception transmitting end receiving second information sent by the perception receiving end. That is, the perception transmitting end may receive the second information sent by the perception receiving end. The second information indicates that the perception transmitting end cannot meet the first target quality of service. For example, the perception receiving end may determine that the perception service performed by the perception transmitting end cannot achieve the first target quality of service and send the second information to the perception transmitting end. When this condition is met, the perception transmitting end may determine to use a perception relay to perform the perception service between the perception transmitting end and the perception receiving end. Optionally, satisfying the first condition may include the perception transmitting end receiving the second information sent by a core network device. That is, the second information is sent by the core network device.

[0146] Optionally, the first condition may include determining the presence of a first perception relay that satisfies the second condition. That is, when at least one first perception relay satisfies the second condition, the perception transmitting end may determine to use the first perception relay to perform the perception task between the perception transmitting end and the perception receiving end. The first perception relay that satisfies the second condition may be one or more. That is, the perception relay used by the perception transmitting end may be one or more first perception relays that satisfy the second condition.

[0147] Optionally, the first condition may include obtaining authorization to use the first perception relay to perform the perception service. That is, upon obtaining authorization to use the first perception relay to perform the perception service, the perception transmitter may determine to use the first perception relay to perform the perception service between the perception transmitter and the perception receiver. For example, the perception transmitter may request authorization from a third party or resource owner to use the first perception relay to perform the perception service. If authorization is obtained, the perception transmitter may determine to use the first perception relay to perform the perception service between the perception transmitter and the perception receiver.

[0148] In some embodiments, the first perception relay includes: a preconfigured first perception relay, which satisfies the second condition; or a first perception relay determined based on the second condition, which satisfies the second condition.

[0149] Optionally, the first awareness relay used may be a preconfigured awareness relay. The preconfigured first awareness relay satisfies the second condition.

[0150] Optionally, the first perception relay used may be a first perception relay determined based on the second condition. That is, when determining to use the first perception relay, the terminal may dynamically discover a first perception relay that meets the second condition and use the first perception relay that meets the second condition to perform the perception service.

[0151] Exemplarily, the second perception relay may be a preconfigured second perception relay, or a second perception relay determined based on the second condition, which will not be elaborated in this disclosure.

[0152] In some embodiments, satisfying the second condition includes at least one of the following: having the ability to enable the executed perception service to achieve the first target service quality; having the ability to transmit the perception signal; the perception transmitting end knows the relevant information of the perception relay; the perception receiving end knows the relevant information of the perception relay.

[0153] Optionally, satisfying the second condition may be having the ability to enable the executed perception service to achieve the first target service quality. That is, when the perception relay is capable of executing the perception service with the first target service quality, it can be used to execute the perception service.

[0154] Alternatively, the second condition may be satisfied by the ability to transmit the perception signal. For example, the signal transmission capability may include supported frequency bands and bandwidths. That is, different frequency bands and bandwidths can transmit different perception signals. For example, a certain frequency band may transmit perception signal A but not perception signal B. In other words, only when the perception relay has the ability to transmit the perception signal of the perception service can it be used to perform the perception service.

[0155] Optionally, the second condition may be satisfied by the perception transmitting end knowing relevant information about the perception relay. For example, the perception transmitting end may store parameters of the perception relay, or the perception transmitting end may detect the status of the perception relay. The perception transmitting end may be either a perception transmitting end or a perception receiving end. Specifically, when the perception transmitting end knows relevant information about the perception relay, the perception relay may be used to perform the perception service. Alternatively, when the perception receiving end knows relevant information about the perception relay, the perception relay may be used to perform the perception service. For example, upon determining relevant information about its own perception relay, the perception transmitting end may determine to use the perception relay to perform the perception service.

[0156] Optionally, the second condition may be satisfied by the fact that the perception receiving end knows the relevant information of the perception relay. For example, the perception receiving end stores the parameters of the perception relay, or the perception transmitting end detects the status of the perception relay, etc. The perception receiving end may be a perception transmitting end or a perception receiving end. That is, when the perception transmitting end is a perception transmitting end, the perception receiving end is a perception receiving end. At this time, the perception receiving end may know the relevant information of the perception relay, and may use the perception relay to perform the perception service. For another example, the perception transmitting end is a perception receiving end, and the perception receiving end is a perception transmitting end. At this time, the perception transmitting end may know the relevant information of the perception relay, and may use the perception relay to perform the perception service. For example, the perception receiving end knows the relevant information of the perception relay and informs the perception transmitting end, that is, the perception transmitting end may determine that the perception receiving end knows the relevant information of the perception relay, and then determine to use the perception relay to perform the perception service.

[0157] In some embodiments, the relevant information of the sensing service includes at least one of the following: the location of the sensing relay; the speed at which the sensing relay transmits the sensing signal; and the time at which the sensing relay transmits the sensing signal.

[0158] Optionally, the relevant information of the perception service includes the location of the perception relay. For example, the location of the perception relay can be used to determine whether the perception relay is within the perception area of ​​the perception transmitter, or whether the service quality that can be achieved at the location of the perception relay can meet the first service quality, etc. For another example, the location of the perception relay can be used to send a perception signal to the perception relay when the perception relay is subsequently used to perform the perception service. When the perception transmitter and / or the perception receiver know the location of the perception relay, the perception relay can be used to perform the perception service. Conversely, when neither the perception transmitter nor the perception receiver knows the location of the perception relay, the perception relay may not be selected to perform the perception service, but this disclosure is not limited to this. For example, in other embodiments, although the perception transmitter and / or the perception receiver do not know the location of the perception relay, they know the time when the perception relay transmits the perception signal, and the perception relay can also be used to perform the perception service. The location of the perception relay can be, for example, coordinates, range, and orientation, but is not limited thereto.

[0159] Optionally, the relevant information for the sensing service may include the speed at which the sensing relay transmits the sensing signal. For example, the speed at which the sensing relay transmits the sensing signal can be used to determine the time it takes for the sensing channel to reach the sensing receiver. If the sensing receiver does not receive the sensing signal within this time range, an abnormality can be determined. In other words, when executing the sensing service, knowing the speed at which the sensing relay transmits the sensing signal can facilitate the execution of the sensing service. Therefore, when the sensing transmitter and / or the sensing receiver know the speed at which the sensing relay transmits the sensing signal, the sensing relay can be used to execute the sensing service.

[0160] Optionally, the relevant information for the awareness service may include the time at which the awareness relay transmits the awareness signal. For example, the time at which the awareness relay transmits the awareness signal may also indirectly indicate the location of the awareness relay. When the time at which the awareness relay transmits the awareness signal is known, the awareness relay may be used to perform the awareness service.

[0161] In some embodiments, determining to use a perception relay to perform a perception service between a perception transmitter and a perception receiver includes: using the perception relay to perform the perception service between the perception transmitter and the perception receiver with relevant parameters. That is, the perception transmitter may control the perception relay to perform the perception service.

[0162] In some embodiments, the relevant parameters include at least one of the following: the radio resources used; the direction of sending the perception signal; the power of sending the perception signal; the phase change of the perception signal received from the perception receiving end; the amplitude change of the perception signal received from the perception receiving end; the second target service quality, the second target service quality is used to indicate the target service quality of the perception relay performing the perception service; the second target perception area for the perception relay to perform the perception service, the second target perception area is used to indicate the target perception area for the perception relay to perform the perception service; the start time; the stop time; the perception method; the perception codec.

[0163] Optionally, the relevant parameters may include radio resources used. That is, the sensing transmitter can control the radio resources of the sensing relay. When the sensing transmitter is a sensing transmitter, the sensing relay is a first sensing relay, that is, the sensing transmitter can control the radio resources used by the first sensing relay to perform the sensing service. When the sensing transmitter is a sensing receiver, the sensing relay is a second sensing relay, that is, the sensing receiver can control the radio resources used by the second sensing relay to perform the sensing service.

[0164] Optionally, the relevant parameter may include a direction in which the perception signal is sent. For example, the direction in which the perception signal is sent is expressed as an angle.

[0165] Optionally, the relevant parameters may include the power of sending the perception signal, that is, the power at which the perception signal is sent.

[0166] Optionally, the relevant parameters may include a phase change of the received perception signal. That is, after the perception relay receives the perception signal from the perception transmitter and before sending the perception signal to the perception receiver, the phase of the perception signal may be changed, and the specific change may be controlled by the perception transmitter.

[0167] Optionally, the relevant parameters may include a change in the amplitude of the received perception signal. That is, after the perception relay receives the perception signal from the perception transmitter and before sending the perception signal to the perception receiver, the perception relay may change the amplitude of the perception signal, and the specific change may be controlled by the perception transmitter.

[0168] Optionally, the relevant parameters may include a second target quality of service. The second target quality of service is used to indicate the target quality of service for the perception relay to perform the perception service. It is understandable that the first target quality of service in the present disclosure is what the requester of the perception service notifies the perception transmitter through the perception service request, that is, it indicates the quality of service that the perception transmitter needs to achieve when performing the perception service. The second quality of service is what the perception transmitter indicates to the perception relay after using the perception relay to perform the perception service. That is, it indicates the quality of service that the perception relay needs to achieve when performing the perception service. The first target quality of service and the second target quality of service may be the same or different.

[0169] Optionally, the relevant parameters may include a second target perception area for the perception relay to perform the perception service. The second target perception area indicates the target perception area for the perception relay to perform the perception service. It is understood that the first target perception area in this disclosure is the one communicated to the perception transmitter by the perception service requester through the perception service request. The second quality of service is the quality of service indicated to the perception relay by the perception transmitter after using the perception relay to perform the perception service. The first target perception area and the second target perception area may be the same or different.

[0170] Optionally, the relevant parameters may include a start time, that is, the time when the awareness service starts, or the time when the awareness signal transmission starts.

[0171] Optionally, the relevant parameters may include a stop time, that is, a time when the sensing service stops, or a time when the transmission of the sensing signal stops.

[0172] Optionally, the relevant parameters may include a sensing method. That is, the sensing relay may control the sensing relay to perform the sensing relay method. For example, if the sensing receiver is capable of processing sensing channel data, the relevant parameters may include the sensing method. However, it is understood that this is merely an example and the present disclosure is not limited thereto.

[0173] Optionally, the relevant parameters may include a perceptual codec, that is, the perceptual transmitter may control the codec of the perceptual relay.

[0174] In some embodiments, radio resources include at least one of the following: frequency band; number of frequency layers; frequency comb; cell identifier; bandwidth; waveform; reference signal format; reference signal identifier; time domain resources; spatial relationship; number of multiple-input multiple-output layers; number of antenna ports. The waveform may include, for example, orthogonal frequency division multiplexing (OFDM) or orthogonal time-frequency space (OTFS), but is not limited thereto. Time domain resource allocation may include, but is not limited to: period; repetition; number of symbols; start time; and duration.

[0175] In some embodiments, if the sensing relay is preconfigured, the sensing transmitter can obtain the sensing relay's sensing area and capabilities. Capabilities include at least: the quality of service achieved by the sensing service being performed; and the ability to transmit sensing signals. Obtaining the sensing relay's sensing area and capabilities facilitates subsequent execution of the sensing service.

[0176] In some embodiments, if the sensing relay is determined based on the second condition, the sensing transmitter can sense the relay's sensing area and capabilities and verify the sensing relay's sensing area and capabilities. It is understood that if the sensing relay is determined based on the second condition, its sensing area and capabilities need to be verified to ensure that the acquired sensing area and capabilities are accurate and avoid errors. Capabilities include at least: achieving the quality of service achieved by the executed sensing service; and the ability to transmit sensing signals.

[0177] In some embodiments, the names of the first information, second information, and third information disclosed herein are not limited, and may be, for example, "indication information," "configuration information," and the like.

[0178] In step S2104 , if the connection between the sensing transmitter 101 and the sensing relay 102 is unavailable, the sensing transmitter 101 establishes a connection between the sensing transmitter 101 and the sensing relay 102 .

[0179] In some embodiments, a connection needs to be established between the sensing transmitter and the sensing relay to ensure the transmission and reception of various types of information and control signaling. For example, the sensing transmitter can be a sensing transmitter or a sensing receiver.

[0180] In some embodiments, a connection is established between the perception transmitting end and the perception relay, including: in response to the perception transmitting end being an access network device and the perception relay being a terminal, establishing a wireless resource control RRC connection between the perception transmitting end and the perception relay; in response to the perception transmitting end being a terminal and the perception relay being an access network device, establishing an RRC connection between the perception transmitting end and the perception relay; in response to the perception transmitting end and the perception relay being two different terminals, establishing a proximity communication PC5 connection between the perception transmitting end and the perception relay.

[0181] Optionally, in response to the perception that the transmitting end is an access network device and the perception relay is a terminal, a radio resource control (RRC) connection is established between the perception transmitting end and the perception relay.

[0182] Optionally, in response to the sensing transmitting end being a terminal and the sensing relay being an access network device, an RRC connection is established between the sensing transmitting end and the sensing relay. That is, when one of the sensing transmitting end and the sensing relay is a terminal and the other is an access network device, an RRC connection can be established between the sensing transmitting end and the sensing relay.

[0183] Optionally, in response to the sensing transmitting end and the sensing relay being two different terminals, a proximity communication (PC) 5 connection is established between the sensing transmitting end and the sensing relay.

[0184] In some embodiments, if the sensing transmitter and the sensing relay are two different access network devices, a connection must exist between the two access network devices. For example, if the sensing transmitter is an access network device and the sensing relay to be selected is also an access network device, the sensing transmitter will select it as the sensing relay only if a connection exists between the two access network devices. Of course, the above scenario is merely illustrative and the present disclosure is not limited thereto.

[0185] In step S2105 , the perception relay 102 sends third information to the perception receiving end 103 .

[0186] In some embodiments, the perception transmitting end 101 or the perception receiving end 103 receives the third information sent by the perception relay 102 .
