Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0118] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0119] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0120] In the embodiments of the present disclosure, communication sensing technology involves sensing nodes and sensing targets in its main scenarios. A sensing target can be an object to be sensed, such as a vehicle, building, drone, or rainfall. A sensing node can be a node that needs to sense the sensing target by sending and / or receiving sensing signals. Examples include base stations, user equipment, and vehicle-mounted devices. A sensing node wants to sense information about the sensing target, such as its position relative to itself, including distance, angle, and speed.

[0121] In the embodiment of the present disclosure, the sensing modes for sensing the sensing target may include the following six modes. In different modes, the corresponding sensing nodes are also different.

[0122] In the embodiment of the present disclosure, the sensing nodes are between access network devices, including sensing mode 1 and sensing mode 2.

[0123] Among them, sensing mode 1 is that the access network equipment performs autonomous transmission and reception. For example, the gNB sends a sensing signal, the sensing signal is reflected after reaching the sensing target, and the gNB also receives the reflected sensing signal.

[0124] Sensing Mode 2 involves the transmission of sensing signals between different access network devices. For example, gNB A transmits a sensing signal, and gNB B receives it. For example, gNB A transmits a sensing signal, which is reflected after reaching the sensing target. Then, gNB B receives the reflected sensing signal.

[0125] In the embodiment of the present disclosure, the sensing nodes are between terminals, including sensing mode 3 and sensing mode 4.

[0126] Among them, perception mode 3 is that the terminal performs autonomous transmission and reception. For example, the UE sends a perception signal, the perception signal is reflected after reaching the perception target, and the UE also receives the reflected perception signal.

[0127] Sensing mode 4 is the transmission of sensing signals between different terminals, for example, UE A sends a sensing signal and UE B receives the sensing signal. For example, UE A sends a sensing signal, the sensing signal is reflected after reaching the sensing target, and then UE B receives the reflected sensing signal.

[0128] In the embodiment of the present disclosure, the perception node is between the access network device and the terminal, including perception mode 5 and perception mode 6.

[0129] Sensing mode 5 involves the UE sending a sensing signal and the gNB receiving it. For example, the UE sends a sensing signal, which is reflected after reaching the sensing target, and then the gNB receives the reflected signal.

[0130] Sensing Mode 6 involves the gNB sending a sensing signal and the UE receiving the sensing signal. For example, the gNB sends a sensing signal, the sensing signal reaches the sensing target and is reflected, and the UE then receives the reflected sensing signal.

[0131] It is understood that in various embodiments of the present disclosure, a sensing node for sending a sensing signal may be referred to as a first node, a sensing sending node, a sensing signal sending node, etc. In various embodiments of the present disclosure, a sensing node for receiving a sensing signal may be referred to as a second node, a sensing receiving node, a sensing signal receiving node, etc. The present disclosure does not limit the names of the above nodes.

[0132] However, in these different sensing modes, detecting a single target cannot meet the requirements for scenarios with multiple targets. This results in very low target sensing efficiency. However, there is currently no consensus on how to achieve sensing, measurement, and reporting of multiple targets.

[0160] In some embodiments, the terminal 101 may be in a radio resource control (RRC) connected state (connected), for example, denoted as RRC_connected.

[0161] In some embodiments, terminal 101 may be in an RRC inactive state (incative), for example, denoted as RRC_incative.

[0162] In some embodiments, terminal 101 may be in an RRC idle state (idle), for example, denoted as RRC_idle.

[0163] In some embodiments, the first signal sent by the second device may be used to sense a sensing target, wherein the sensing target may be considered as a target that needs to be sensed.

[0164] For example, the sensing target may be a building, a moving object, the external environment, etc. The external environment may include temperature, humidity, whether it is raining, etc.

[0165] It is understood that after the first signal is transmitted by the second device and reaches the sensing target, the first signal may be reflected by the sensing target, so that the first device receives the reflected first signal. The first device may use the reflected first signal to perform measurements to achieve sensing of the sensing target, such as positioning.

[0166] In some embodiments, the first signal may be reflected by a sensing target or an obstacle.

[0167] In some embodiments, the name of the first signal is not limited, and it can be, for example, "perception information", "first signal", "sensory information", "sensory signal", etc.

[0168] In some embodiments, the first signal may be a positioning reference signal (PRS).

[0169] For example, the first signal may be a PRS sent and / or received between different access network devices.

[0170] For example, the first signal may be a PRS sent and / or received between the access network device and the terminal.

[0171] In some embodiments, the first signal may be a sidelink positioning reference signal (SL-PRS).

[0172] For example, the first signal may be an SL-PRS transmitted and / or received between different terminals.

[0173] In some embodiments, the first signal may be a sounding reference signal (SRS).

[0174] For example, the first signal may be an SRS sent and / or received between different access network devices.

[0175] For example, the first signal may be an SRS sent and / or received between the access network device and the terminal.

[0176] In some embodiments, the first signal may be a SL-SRS.

[0177] For example, the first signal may be an SL-SRS sent and / or received between different terminals.

[0178] In some embodiments, the first signal may be a reference signal used for sensing.

[0179] For example, a reference signal used for sensing may be referred to as a sensing reference signal. It is understood that the sensing reference signal may be a newly defined reference signal used for sensing. The present disclosure does not limit the name of such reference signal.

[0180] In some embodiments, the first signal may include at least one of the following information: PRS; SRS; SL-PRS; SL-SRS; perception reference signal.

[0181] Step S2102: The first device measures the first signal to obtain first information corresponding to the first signal.

[0182] In some embodiments, the first device receives the first signal and may measure the first signal, and may obtain first information corresponding to the first signal.

[0183] In some embodiments, the first information includes a measurement value obtained by measuring the first signal. Therefore, the first information can represent a measurement condition of the first signal.

[0184] In some embodiments, the first information may also be referred to as "signal measurement information", "perception signal measurement information", "communication signal measurement information", "measurement value", "measurement quantity", etc., which is not limited in this disclosure.

[0185] In some embodiments, the first information may include at least one first parameter. The first parameter may be used to indicate the aspect of the first signal measured by the first device. Each first parameter may correspond to one or more first values. The first value represents a numerical value obtained by the first device measuring the first signal with respect to the first parameter.

[0186] For example, taking the first signal as a perception signal, the first device as a perception receiving node, the first parameter as a reference signal received power (RSRP), and the first value as a measurement value as an example, the perception receiving node may measure the perception signal to obtain first information. The first information may include one or more RSRP measurement values ​​corresponding to the perception signal. Different RSRP measurement values ​​corresponding to the perception signal correspond to different perception targets.

[0187] In some embodiments, the first parameter may include the RSRP of the first signal.

[0188] In some embodiments, the first parameter may include a reference signal receiving power per path or a reference signal receiving power of the ith path (RSRPP) of the first signal, where i is a positive integer.

[0189] The RSRPP can indicate the path number. For example, the first path may have RSRPPs corresponding to multiple different sensing targets, and the second path may have RSRPPs corresponding to multiple different sensing targets. RSRP can be path-independent. That is, for a given sensing target, the RSRP corresponding to the sensing target can be obtained based on the RSRPPs of each path.

[0190] In some embodiments, the first parameter may include a reference signal received quality (RSRQ) of the first signal.

[0191] In some embodiments, the first parameter may include a signal to interference plus noise ratio (SINR) of the first signal.

[0192] In some embodiments, the first parameter may include an arrival time of the first signal.

[0193] In some embodiments, the first parameter may include a reference signal time difference (RSTD) of the first signal.

[0194] In some embodiments, RSTD may be the difference between the time when the first signal is received and a preset reference time, or RSTD may be the difference between the times when different first signals are received. RSTD may be used for downlink (DL) measurements, sidelink (SL) measurements, and / or measurements between access network devices.

[0195] In some embodiments, terms such as "downlink", "downlink", "physical downlink" can be interchangeable, and terms such as "side", "side link", "side link", "side communication", "side link communication", "direct connection", "direct link", "direct communication", and "direct link communication" can be interchangeable.

[0196] In some embodiments, the first parameter may include a Rx-Tx time difference of the first signal, that is, a difference between a sending time and a receiving time of the first signal.

[0197] In some embodiments, the first parameter may include a relative time of arrival (RTOA) of the first signal.

[0198] In some embodiments, RTOA is the difference between the time when the first signal is received and a preset reference time. RTOA is used for uplink (UL) measurement, SL measurement, and / or measurement between access network devices.

[0199] In some embodiments, the terms "uplink", "uplink", "physical uplink", etc. can be used interchangeably.

[0200] In some embodiments, the first parameter may include an angle of arrival of the first signal.

[0201] In some embodiments, the first parameter may include a departure angle of the first signal.

[0202] In some embodiments, the first parameter may include a distance between the sensing target and the first device, wherein the first device is configured to receive the first signal.

[0203] In some embodiments, the first parameter may include a distance between the sensing target and a second device, wherein the second device is configured to send the first signal.

[0204] In some embodiments, the first parameter may include a moving speed of the perception target.

[0205] In some embodiments, the first parameter may include a Doppler parameter of the first signal.

[0206] For example, the Doppler parameter may be at least one of a Doppler frequency offset and a Doppler spread.

[0207] In some embodiments, each first parameter in the first information may correspond to one or more measurement values. In the case where a first parameter corresponds to multiple measurement values, different measurement values ​​may correspond to different perception targets.

[0208] That is, the first device can measure the same sensing signal arriving at different times and / or angles to obtain measurement values ​​corresponding to different sensing targets. A sensing signal with a single arrival time and / or arrival angle can be used to perceive a single sensing target. Because the second device transmits a sensing signal, the sensing signal arrives at different sensing targets at different times and / or angles due to their different locations. Therefore, after being reflected by different sensing targets, the sensing signal arrives at the first device at different times and / or angles. For example, the sensing signal corresponding to arrival time 1 and / or arrival angle 1 is used to perceive the first sensing target, while the sensing signal corresponding to arrival time 2 and / or arrival angle 2 is used to perceive the second sensing target. The first parameter is the RSRP of the sensing signal. The first device can measure the RSRP of the sensing signal corresponding to arrival time 1 and / or arrival angle 1 to obtain a first RSRP measurement value; and the first device can measure the RSRP of the sensing signal corresponding to arrival time 2 and / or arrival angle 2 to obtain a second RSRP measurement value. The first information can then include multiple RSRP measurement values, namely, the first RSRP measurement value and the second RSRP measurement value.

[0209] Of course, the first parameter may also include the SINR of the perceived signal. The first device may also measure the SINR of the perceived signal corresponding to arrival time 1 and / or arrival angle 1 to obtain a first SINR measurement value; and the first device may also measure the SINR of the perceived signal corresponding to arrival time 2 and / or arrival angle 2 to obtain a second SINR measurement value. The first information may then include multiple RSRP measurement values, namely, a first RSRP measurement value and a second RSRP measurement value; and may also include multiple SINR measurement values, namely, a first SINR measurement value and a second SINR measurement value.

[0210] It will be understood that the first parameters in the above embodiments, namely RSRP and SINR, are merely exemplary descriptions. Of course, the first parameter may be any one or more of the above-mentioned RSRP, RSRPP, RSRQ, SINR, arrival time, RSTD, Rx-Tx time difference, RTOA, arrival angle, departure angle, distance between the sensing target and the first signal receiving node, distance between the sensing target and the first signal transmitting node, moving speed, and Doppler parameter, and this disclosure is not limited thereto.

[0221] For example, the terminal 101 sends the eighth information to the access network device 102 .

[0222] In some embodiments, the first device is the terminal 101, and the network device may be a first network element.

[0223] For example, the terminal 101 sends the eighth information to the first network element.

[0224] In some embodiments, the terminal may forward the eighth information to the first network element via the access network device. Alternatively, the terminal may directly send the eighth information to the first network element via an interface or protocol between the first network element and the terminal. This disclosure is not limited thereto.

[0225] In some embodiments, the first device is a first access network device, and the network device may be a second access network device, that is, the first device and the network device are different access network devices 102 .

[0226] For example, the first access network device sends the eighth information to the second access network device. For example, the first access network device may send the eighth information to the second access network device through an interface between different access network devices.

[0230] In some embodiments, the third device receives the eighth information sent by the first device.

[0231] In some embodiments, the third device is the same device as the second device.

[0232] In some embodiments, the third device is a different device from the second device.

[0233] In some embodiments, the third device and the network device are different devices.

[0234] In some embodiments, the first device is a first terminal, and the third device may be a second terminal, that is, the first device and the third device are different terminals 101 .

[0235] For example, the first terminal sends the eighth information to the second terminal. For example, the first terminal may send the eighth information to the second terminal through SL communication.

[0236] For another example, assuming that the first device is a first terminal, the second device is a second terminal, and the third device is a third terminal, the first terminal may send the eighth information to the third terminal. The third terminal and the second terminal may be the same terminal, or the third terminal and the second terminal may be different terminals.

[0237] In some embodiments, the first device is a terminal 101 , and the third device may be an access network device 102 .

[0238] For example, the terminal 101 sends the eighth information to the access network device 102 .

[0239] For another example, assuming that the first device is a first terminal, the second device is a first access network device, and the third device is a third access network device, the first terminal may send the eighth information to the third access network device. The third access network device and the first access network device may be the same access network device, or the third access network device and the first access network device may be different access network devices.

[0240] In some embodiments, the first device is the terminal 101, and the third device may be a first network element.

[0241] For example, the terminal 101 sends the eighth information to the first network element.

[0242] In some embodiments, the terminal may forward the eighth information to the first network element via the access network device. Alternatively, the terminal may directly send the eighth information to the first network element via an interface or protocol between the first network element and the terminal. This disclosure is not limited thereto.

[0243] In some embodiments, the first device is a first access network device, and the third device may be a third access network device, that is, the first device and the third device are different access network devices 102 .

[0244] For example, the first access network device sends the eighth information to the third access network device. For example, the first access network device may send the eighth information to the third access network device through an interface between different access network devices.

[0245] For another example, assuming that the first device is a first access network device, the second device is a second access network device, and the third device is a third access network device, the first access network device may send the eighth information to the third access network device. The third access network device and the second access network device may be the same access network device, or the third access network device and the second access network device may be different terminals.

[0246] In some embodiments, the first device is the access network device 102, and the third device may be a first network element.

[0247] For example, the access network device 102 sends the eighth information to the first network element. For example, the access network device 102 may send the eighth information to the first network element through an interface or protocol between the first network element and the access network device.

[0248] It is understandable that if the first device and the third device are the same terminal, or the same access network device, the first device does not need to send the eighth information to its own device.

[0249] It is understandable that the second device that sends the first signal and the third device that receives the eighth information may be the same device; the second device that sends the first signal and the third device that receives the eighth information may also be different devices. This disclosure does not limit this.

[0250] In some embodiments, the eighth information is used to indicate the number of first values ​​corresponding to the first parameter in the first information supported by the first device. The eighth information can be sent via terminal capability reporting information. The first device is a terminal.

[0251] Of course, the terminal capability reporting information is mainly used to indicate the capabilities of the terminal. The terminal capability reporting information can also be called "terminal capability information", "device capability information", "capability reporting information", "capability feedback information", etc. This disclosure does not limit the name of the terminal capability reporting information.

[0252] It is understood that the number of first values ​​corresponding to the first parameter can be the same as the number of sensing targets. In other words, different first values ​​can correspond to different sensing targets. In other words, different first values ​​are obtained by measuring signals reflected from different sensing targets or obstacles.

[0253] In some embodiments, the eighth information is used to indicate that the first device supports a capability of sending the first information.

[0254] The capability of sending the first information includes sending the number of first values ​​corresponding to the first parameter in the first information.

[0255] It is understood that the number of first values ​​in the first information, that is, the maximum number of first values ​​corresponding to the perception targets that can be included in the first information, can be a positive integer greater than or equal to 1.

[0256] In some embodiments, the eighth information may be referred to as "capability information", "terminal capability information", "device capability information", "terminal capability reporting information", etc. This disclosure does not limit the name of the eighth information.

[0257] For example, when the first device is a terminal, the eighth information may indicate the maximum number of first parameters and / or first values ​​of perception targets that the terminal supports reporting simultaneously.

[0258] It is understood that the first device sending the eighth information considers the case where the first device is a terminal. After measuring the first signal and obtaining the first information, the first device may send the first information to at least one of the network device and the second device. The second device may be a terminal, an access network device, or a first network element. For example, the first device sends the first information to at least one of the access network device, the first network element, and the terminal. Of course, the network device and the second device may be the same device or different devices.

[0259] Then, the network device and / or the second device that receives the eighth information can determine the capabilities of the first device and further determine the possible size of the first information. This allows the network device and / or the second device that receives the eighth information to determine how much resources to allocate for the first device to transmit the first information based on the size of the first information. Furthermore, the network device and / or the second device that receives the eighth information can also better decode subsequently received first information based on the size.

[0260] Of course, the first device may also send the eighth information when the first device is an access network device or a first network element, and this disclosure does not limit this. In other words, regardless of whether the first device is a terminal, an access network device, or a first network element, it can send the eighth information to any device other than the first device. For example, the first device can send the eighth information to any terminal, access network device, and / or first network element other than the first device. The any device other than the first device may include at least one of a network device and a second device.

[0261] In some embodiments, there is no strict order in which step S2103 is executed, and there is no strict order in which step S2101 or step S2102 is executed. In other words, step S2103 may be executed after step S2102, between step S2101 and step S2102, or before step S2101, and this disclosure does not limit this.

[0262] Step S2104: The first device sends first information to the network device.

[0263] In some embodiments, the first device sends first information to the network device.

[0264] In some embodiments, the network device receives first information sent by the first device.

[0265] In some embodiments, the first device sends the first information to the second device.

[0266] In some embodiments, the second device receives the first information sent by the first device.

[0267] It can be understood that the specific implementation process of sending information in step S2104 can refer to step S2103, the only difference is that the information sent is the first information, and this disclosure will not go into details here.

[0268] Step S2105: The first device determines second information corresponding to the first signal.

[0269] In some embodiments, the second information is used to represent configuration information corresponding to the first signal.

[0270] In some embodiments, the second information can be called "perception signal configuration information", "perception signal configuration", "communication signal configuration information", "communication signal configuration", etc. This disclosure does not limit the name of the second information.

[0271] In some embodiments, the second information may include a resource identifier of the first signal.

[0272] In some embodiments, the identifier may be an identity (ID) or an index.

[0273] For example, the second information includes a perception signal resource ID. It is understood that the perception signal resource ID can be used to determine the perception signal corresponding to the resource. This indicates that the first information is obtained based on the perception signal. The first parameter in the first information may have one or more first values. A single first value indicates that a single perception target is perceived; multiple first values ​​indicate that multiple perception targets are perceived.

[0274] In some embodiments, the second information may include a resource set identifier of the first signal.

[0275] For example, the second information includes a sensory signal resource set ID. One sensory signal resource set ID corresponds to one sensory signal resource set. One sensory signal resource set may include one or more sensory signal resources. Therefore, one sensory signal resource set ID indicates one sensory signal resource set.

[0276] In some embodiments, the second information may include a frequency identifier of the first signal.

[0277] For example, the second information includes a frequency ID. The frequency ID may indicate a frequency band on which the perception signal is transmitted, for example, the frequency ID may indicate at least one of a frequency layer, a component carrier, and a carrier frequency.

[0278] In some embodiments, the second information may include third information, where the third information is used to indicate line of sight (LOS) and / or non line of sight (NLOS).

[0279] In various embodiments of the present disclosure, the third information may also be referred to as “LOS and / or NLOS indication”, and the present disclosure does not limit the name of the third information.

[0280] It can be understood that the LOS and / or NLOS indication can indicate whether the transmission path of the first signal between the signal sending node and the signal receiving node passes through an obstacle. When the first signal is a sensing signal, the signal sending node is a sensing sending node, and the signal receiving node is a sensing receiving node.

[0281] For example, LOS means that the transmission path of the first signal between the signal sending node and the signal receiving node does not pass through any obstacles, and the first signal propagates directly to the signal receiving node. For another example, NLOS means that the transmission path of the first signal between the signal sending node and the signal receiving node passes through an obstacle, and the first signal propagates to the signal receiving node after being reflected by the obstacle.

[0282] For example, the LOS and / or NLOS indication can be a hard indication, that is, a 0 or 1. For example, a 1-bit indication can be used, with 0 indicating LOS and 1 indicating NLOS; or, alternatively, 1 indicating LOS and 0 indicating NLOS. This disclosure does not limit the meaning of the specific value of this bit, and it can be adaptively adjusted according to the situation.

[0283] For another example, the LOS and / or NLOS indication may be a soft indication, i.e., any value between 0 and 1. It may be expressed as a decimal, such as 0.3, 0.78, 0.146, etc. It will be appreciated that the closer the value is to 0, the closer it is to LOS, and the closer the value is to 1, the closer it is to NLOS; conversely, the closer the value is to 0, the closer it is to NLOS, and the closer the value is to 1, the closer it is to LOS.

[0284] In some embodiments, the second information may include fourth information, where the fourth information is used to indicate a group of error parameters corresponding to the same perception target.

[0285] In various embodiments of the present disclosure, the fourth information may also be referred to as an "error group indication," and the present disclosure does not limit the name of the fourth information.

[0286] For example, the same error group indicator may correspond to the same perception target. In other words, first values ​​of different first parameters corresponding to the same perception target may share the same error group indicator.

[0287] In some embodiments, the fourth information is used to indicate an error between the baseband and the radio frequency, and a radio frequency position.

[0288] In some embodiments, the fourth information may include a timing error indicator.

[0289] For example, it may be a time error identifier or a time error group identifier, such as a time error ID or a time error group ID.

[0290] In some embodiments, the fourth information may include a phase error identifier.

[0291] For example, it may be a phase error identifier or a phase error group identifier, such as a phase error ID or a phase error group ID.

[0292] In some embodiments, the fourth information may include an angle error indicator.

[0293] For example, it may be an angle error identifier or an angle error group identifier, such as an angle error ID or an angle error group ID.

[0294] In some embodiments, the fourth information may include an antenna port identifier.

[0295] For example, it may be an antenna port ID.

[0296] In some embodiments, the fourth information may include an antenna identification.

[0297] For example, it can be the antenna ID.

[0298] In some embodiments, the fourth information may include an antenna reference point identifier.

[0299] For example, it can be the antenna reference point ID.

[0300] In some embodiments, the fourth information may further include at least one of the following: a time error identifier; a phase error identifier; an angle error identifier; an antenna port identifier; an antenna identifier; or an antenna reference point identifier.

[0301] In some embodiments, the second information may include fifth information, where the fifth information is used to indicate the confidence of the first value.

[0302] In various embodiments of the present disclosure, the fifth information may also be referred to as a “credibility indication”, and the present disclosure does not limit the name of the fifth information.

[0303] For example, the credibility indicator can be any value between 0 and 1, including the two endpoint values ​​of 0 and 1. This credibility indicator can be used to indicate the credibility of a first value. For example, 0 can represent the least credibility and 1 can represent the most credibility; or 0 can represent the most credibility and 1 can represent the least credibility. This disclosure does not limit the meaning of the specific credibility values, and can be adjusted appropriately according to actual circumstances.

[0304] For example, the trustworthiness indicator can be a hard value, i.e., 0 or 1. For example, a 1-bit indicator can be used, with 0 indicating untrustworthy and 1 indicating trustworthy; or, alternatively, 1 indicating untrustworthy and 0 indicating trustworthy. This disclosure does not limit the meaning of the specific value of this bit, and it can be adaptively adjusted according to the situation.

[0305] For another example, the credibility indicator can be a soft indicator, that is, an arbitrary value between 0 and 1. It can be expressed as a decimal, such as 0.3, 0.78, 0.146, etc. It is understood that the closer the value is to 0, the less credible it is, and the closer the value is to 1, the more credible it is; or vice versa, the closer the value is to 0, the more credible it is, and the closer the value is to 1, the less credible it is.

[0306] In some embodiments, the second information may include an identification of the perception target.

[0307] For example, the second information may include a perception target ID, which is used to indicate which perception target the first device perceives, and may also be considered to indicate which perception target other parameters in the first information or the second information correspond to.

[0308] For example, assuming the first device is a sensing receiving node, the sensing target ID can be used to indicate the sensing target corresponding to each measurement quantity in the sensing receiving node. Measurement quantities for the same sensing target ID represent measurement quantities corresponding to sensing signals reflected from the same sensing target. For example, the first information may include two time measurement values ​​and two angle measurement values. The second information may indicate that the first time measurement value corresponds to sensing target 1, and the second time measurement value corresponds to sensing target 2. The second information may indicate that the first angle measurement value corresponds to sensing target 1, and the second angle measurement value corresponds to sensing target 2.

[0309] In some embodiments, the second information may include sixth information, where the sixth information is used to indicate an association relationship between the first values ​​corresponding to at least two first parameters.

[0310] In various embodiments of the present disclosure, the sixth information may also be referred to as an "association relationship indication," and the present disclosure does not limit the name of the sixth information.

[0311] It is understandable that the association relationship indication may indicate the relationship between the first values ​​corresponding to the plurality of first parameters in the first information and the perception target. For example, if two first parameters correspond to the same association relationship indication, it means that the two first parameters correspond to the same perception target.

[0312] For example, assuming that the first device is a perception receiving node, the sixth information can indicate the association relationship corresponding to each first parameter in the perception receiving node. For the first parameter with an association relationship, that is, it is represented as the first parameter obtained by measuring the perception signal reflected by the same perception target. For example, the first information includes two time measurement values ​​and two angle measurement values. The sixth information can indicate that the first time measurement value and the first angle measurement value have an association relationship, that is, they correspond to a perception target, such as perception target 1; the sixth information can also indicate that the second time measurement value and the second angle measurement value have an association relationship, that is, they correspond to a perception target, such as perception target 2.

[0313] In some embodiments, the first values ​​corresponding to at least two first parameters may correspond to a seventh information.

[0314] That is to say, one or more first values ​​corresponding to different first parameters can share the same seventh information.

[0315] In some embodiments, first values ​​corresponding to different first parameters of at least two first parameters correspond to different seventh information.

[0316] That is to say, different first parameters correspond to one or more first values ​​respectively, each first parameter may correspond to a seventh information respectively, and different first parameters correspond to different seventh information.

[0317] In some embodiments, the seventh information may include at least one of the third information, the fourth information, and the fifth information.

[0318] For example, the seventh information may include at least one of a LOS and / or NLOS indication, an error group indication, and a confidence level indication.

[0319] For example, the first information includes at least one first parameter corresponding to at least one perception target, and each first parameter corresponds to at least one first value. Assuming that the at least one first parameter included in the first information includes a time measurement value and an angle measurement value, the time measurement value and the angle measurement value may be for the same perception target. In this case, the time measurement value and the angle measurement value for the same perception target may share the seventh information corresponding to the perception target. For example, the seventh information in the second information, i.e., the LOS and / or NLOS indication, the error group indication, the confidence level indication, etc., may be shared.

[0320] The time measurement values ​​mentioned in the above embodiments may include RSTD, RTOA, receiving and sending time, etc. The angle measurement values ​​may include departure angle, arrival angle, etc.

[0321] In some embodiments, there is no strict order in which step S2105 and step S2104 must be executed. That is, step S2104 may be executed first and then step S2105, or step S2105 may be executed first and then step S2104, or both step S2104 and step S2105 may be executed simultaneously, which is not limited in this disclosure.

[0328] In some embodiments, the second information and the first information may be carried by the same signaling.

[0329] In some embodiments, the second information and the first information may be carried respectively through different signaling.

[0434] In some embodiments, the perception signal receiving node receives the perception signal, obtains a measurement value, and reports the measurement value, wherein the measurement value is for a measurement quantity of the perception signal and includes one or more measurement values.
