[0052] The term “perception” in this application may also be understood as meaning at least one of positioning, ranging, speed measurement, angle measurement, target imaging, target detection, target tracking, and target recognition.

[0053] Some key terms in this application are briefly introduced as follows:

[0054] Decibel milliwatt (dBm) is a pure unit of measurement that represents the absolute value of power.

[0055] FIG1 shows a schematic diagram of a network architecture 100 provided by an exemplary embodiment of the present application. The network architecture 100 includes: a terminal device 10 , an access network device 20 , and a core network device 30 .

[0056] The terminal device 10 may refer to a user equipment (UE), an access terminal, a user unit, a user station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a wireless communication device, a user agent, or a user device. Optionally, the terminal device 10 may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in the fifth generation mobile communication system (5GS) or a terminal device in the future evolved public land mobile communication network (PLMN), etc., and the embodiments of the present application are not limited to this. For the convenience of description, the devices mentioned above are collectively referred to as terminal devices. The number of terminal devices 10 is usually multiple, and one or more terminal devices 10 may be distributed in each cell managed by the access network device 20, and the terminal device 10 includes a candidate perception auxiliary device.

[0057] The access network device 20 is a device deployed in the access network to provide wireless communication functions for the terminal device 10. The access network device 20 may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems using different wireless access technologies, the names of devices with access network device functions may be different. For example, in the fifth generation new radio (5G NR) system, it is called the next generation base station (gNodeB, gNB). With the evolution of communication technology, the name of "access network device" may change. For the convenience of description, in the embodiment of the present application, the above-mentioned devices that provide wireless communication functions for the terminal device 10 are collectively referred to as access network devices. Optionally, through the access network device 20, a communication relationship can be established between the terminal device 10 and the core network device 30. For example, in a Long Term Evolution (LTE) system, the access network device 20 may be an Evolved Universal Terrestrial Radio Access Network (EUTRAN) or one or more evolved base stations in the EUTRAN. In a 5G NR system, the access network device 20 may be a Radio Access Network (RAN) or one or more gNBs in the RAN. In the embodiments of the present application, unless otherwise specified, a network device refers to an access network device 20, such as a base station.

[0058] The core network device 30 is deployed in the core network. The functions of the core network device 30 are mainly to provide user connections, user management, and service bearer, and to provide an interface to the external network as a bearer network. For example, the core network equipment in the 5G NR system includes the Access and Mobility Management Function (AMF) network element, the User Plane Function (UPF) network element, and the Session Management Function (SMF) network element.

[0059] In some embodiments, the access network device 20 and the core network device 30 communicate with each other via an air interface technology, such as the NG interface in the 5G NR system. The access network device 20 and the terminal device 10 communicate with each other via an air interface technology, such as the Uu interface.

[0060] 2 shows a schematic diagram of a network system architecture 200 provided by related art. The network system architecture 200 includes: a terminal device 10 , an access network device 20 and a core network device 30 .

[0061] Among them, the core network device 30 includes network slice selection function (NSSF), authentication server function (AUSF), unified data management (UDM), access and mobility management function (AMF), session management function (SMF), policy control function (PCF), user plane function (UPF), and sensing control function (SF).

[0062] The UE establishes an access layer connection with the access network (AN) through the Uu interface, exchanging access layer messages and wireless data transmission. The UE establishes a non-access stratum (NAS) connection with the AMF through the N1 interface, exchanging NAS messages. AMF is the mobility management function in the core network, and SMF is the session management function in the core network. In addition to managing the mobility of the UE, the AMF is also responsible for forwarding session management-related messages between the UE and the SMF. PCF is the policy management function in the core network, responsible for formulating policies related to the mobility management, session management, and billing of the UE. PCF transmits data with the external application function (AF) through the N5 interface. UPF is the user plane function in the core network, which transmits data with the external data network (DN) through the N6 interface and with the AN through the N3 interface.

[0063] The "5G NR system" in the embodiments of the present application may also be referred to as a 5G system or an NR system, but those skilled in the art will understand its meaning. The technical solutions described in the embodiments of the present application may be applicable to LTE systems, 5G NR systems, subsequent evolution systems of 5G NR systems, and other communication systems such as Narrow Band Internet of Things (NB-IoT) systems, and this application does not limit this.

[0064] Current cellular networks, including 5G networks, are used solely for communication. However, the radio electromagnetic wave signals used by cellular networks can be used not only for wireless data transmission and communication but also for environmental perception. For example, they can be used to detect user movements or gestures, monitor breathing, measure terminal movement speed, perform environmental imaging, and monitor weather conditions. Therefore, in the future, cellular networks will not only be used for communication and data transmission, but also for acquiring sensory information.

[0065] In the related art, 5G networks support perception capabilities, and support perception functions in the 3rd Generation Partnership Project (3GPP) network through SF network elements and corresponding processes, as shown in Figure 3, which shows a flowchart of a method for controlling access network equipment or UE to perform UE-level perception operations provided by the related art. The method includes the following steps:

[0066] Step 301: The application (AF) sends a perception request.

[0067] The application (AF) sends a perception request for the perception service UE to the core network of the 3GPP network. The perception request carries the information of the perception service UE and the perception type.

[0068] The main wireless sensing modes of synaesthesia integration are shown in Figure 4, including:

[0069] a) Base station (access network equipment) echo sensing link: The base station (access network equipment) sends a sensing signal and receives an echo signal;

[0070] b) Inter-base station sensing link: Base station B receives the sensing signal sent by base station A;

[0071] c) Air interface uplink perception link: The base station receives the perception signal sent by the terminal;

[0072] d) Air interface downlink perception link: The terminal receives the perception signal sent by the base station;

[0073] e) Terminal echo sensing link: The terminal sends a sensing signal and receives an echo signal;

[0074] f) Inter-terminal perception link: Terminal B receives the perception signal sent by terminal A.

[0075] Based on the above scenarios, the perception types include: access network device echo perception, access network device inter-device perception, air interface uplink perception, air interface downlink perception, terminal device echo perception, and inter-terminal device perception.

[0076] Step 302: The perception control network element sends a perception instruction.

[0077] The core network selects access network devices or auxiliary UEs participating in sensing through the sensing control network element (SF) or AMF, triggers the sensing-related wireless measurement process, starts measuring sensing information, and generates sensing results. For example, the SF sends a sensing instruction to the AMF, which carries information about the sensing service UE and the sensing type.

[0078] Step 303: The mobility management network element determines the UE sensing mode or the base station sensing mode.

[0079] Step 304: The mobility management network element sends a sensing instruction.

[0080] When the perception type is air interface uplink perception, the AMF sends a perception instruction to the access network device, and the perception instruction includes the perception type.

[0081] Step 305: The access network device and the perception service UE perform access layer signal measurement.

[0082] Step 306: The access network device generates perception data.

[0083] Step 307: The mobility management network element sends a sensing instruction.

[0084] When the perception type is air interface downlink perception, the AMF sends a perception instruction to the perception service UE, and the perception instruction includes the perception type.

[0085] Step 308: The sensing service UE and the access network device perform access layer signal measurement.

[0086] In the early stages of 5G communication perception integration, the perception signals used for perception can reuse existing air interface signals, such as the Sounding Reference Signal (SRS), Demodulation Reference Symbol (DMRS), Channel State Information Reference Signal (CSI-RS), Phase Tracking Reference Signal (PTRS), and Positioning Reference Signal (PRS). Reusing existing air interface signals to perform perception does not introduce excessive air interface enhancements.

[0087] Step 309: The sensing service UE generates sensing data.

[0088] FIG5 shows a flowchart of a sidelink discovery process mode A provided by the related art. This mode defines two roles for UEs participating in the discovery process: (1) Announcing UE: This UE announces certain information that can be used by nearby UEs with discovery permissions. (2) Monitoring UE: This UE monitors certain information of interest in the vicinity of the announcing UE.

[0089] In this mode, the announcing UE broadcasts a sensing discovery message at a predefined discovery interval. Interested monitoring UEs read and process the sensing discovery message. This mode is equivalent to "I am here" because the announcing UE broadcasts information about itself. This mode, which includes an announcing UE 510, a first monitoring UE 520, and a second monitoring UE 530, is described as follows:

[0090] Step 501: The announcement UE sends an announcement message.

[0091] The announcing UE 510 broadcasts an announcement message, ie, a sensing discovery message, at a predefined discovery interval. The first monitoring UE 520 and the second monitoring UE 530 that are interested in the announcement message receive and process the announcement message.

[0092] Figure 6 shows a flowchart of sidelink discovery process mode B, as provided in the related art. This mode defines two roles for UEs participating in the discovery process. (1) Discovering UE: The UE sends a request message that includes information about what the UE is interested in discovering. (2) Discovered UE: The UE that receives the request message can respond with information related to the request message.

[0093] This mode is equivalent to "Who's there / Are you there?", because the discovery UE sends a request message and hopes to receive information about the UE that sends a response message. This information can be a Proximity Services (ProSe) application identifier corresponding to a group, and members of the group can respond.

[0094] Taking the mode including the discovery UE 610, the first discovered UE 620, and the second discovered UE 630 as an example for description, the mode includes the following steps:

[0095] Step 601: Discovery UE sends a request message.

[0096] It is discovered that UE 610 sends a request message and hopes to receive a response message from other UEs.

[0097] Step 602: The first discovered UE sends a response message.

[0098] After receiving the request message, the first discovered UE 620 sends a response message to the discovering UE 610 . The response message includes relevant information of the first discovered UE 620 .

[0099] Step 603: The second discovered UE sends a response message.

[0100] After receiving the request message, the second discovered UE 630 sends a response message to the discovering UE 610 . The response message includes relevant information of the second discovered UE 630 .

[0101] The present application provides an information indication method, in which a candidate perception-assisted device (UE) can indicate a first condition to a network device or other UE, thereby indicating that the candidate perception-assisted device acts as a perception-assisted device participating in a perception process when the first condition is met.

[0102] FIG7 shows a flowchart of an information indication method provided by an exemplary embodiment of the present application. The method is executed by a candidate perception assistance device, and the method includes:

[0103] Step 710: Send indication information, where the indication information is used to instruct the candidate perception assistance device to serve as a perception assistance device participating in the perception process if the first condition is met.

[0104] The indication information is used to indicate that the candidate perception assistance device can, is allowed to, or agrees to serve as a perception assistance device participating in the perception process if the first condition is met.

[0105] In this embodiment, the first condition is used to indicate that the perception condition of the candidate perception assistance device is better than the threshold value. For example, when the distance between the perception target and the candidate perception assistance device is less than the threshold value, the first condition is met.

[0106] Alternatively, the first condition is used to indicate that the energy consumption of the candidate perception-assisting device during the perception process is less than a threshold value. For example, when the current candidate perception-assisting device is selected as the perception-assisting device, the energy consumption is less than the threshold value, and the first condition is satisfied.

[0107] Alternatively, the first condition is used to indicate that the candidate sensing auxiliary device is related to the current sensing service. For example, when the current candidate sensing auxiliary device serves as a sensing receiving node or a sensing transmitting node and is related to the current sensing service, the first condition is satisfied.

[0108] Alternatively, the first condition is used to assist the sensing node device in selecting the best candidate sensing assisting device from among multiple candidate sensing assisting devices as the sensing assisting device. For example, if, among three candidate sensing assisting devices, the first candidate sensing assisting device has the best signal quality with the sensing node device, the sensing node device selects the first candidate sensing assisting device as the sensing assisting device.

[0109] In some embodiments, the indication information includes: threshold information related to the first condition, wherein the threshold information includes at least one of the following:

[0110] (1) The first distance threshold between the candidate perception auxiliary device and the perception target;

[0111] (2) a second distance threshold between the candidate sensing auxiliary device and the sensing node device;

[0112] (3) Signal quality threshold between candidate sensing auxiliary devices and sensing node devices;

[0113] (4) The perception link is the probability threshold of the Line Of Sight (LOS) path. The perception link includes the wireless link when the candidate perception auxiliary device perceives the perception target.

[0114] Regarding (1) the first distance threshold between the candidate perception auxiliary device and the perception target.

[0115] When the distance between the candidate perception assistance device and the perception target is less than or equal to a first distance threshold, the first condition is satisfied, and the candidate perception assistance device may be allowed or agreed to participate in the perception process as a perception assistance device. For example, the first distance threshold is 100 meters. If the distance between the candidate perception assistance device and the perception target is 50 meters, the first condition is satisfied, and the candidate perception assistance device may be allowed or agreed to participate in the perception process as a perception assistance device.

[0116] Regarding (2) the second distance threshold between the candidate perception auxiliary device and the perception node device.

[0117] If the distance between the candidate perception-assistant device and the perception node device is less than or equal to a second distance threshold, the first condition is satisfied, and the candidate perception-assistant device may be permitted or agreed to participate in the perception process as a perception-assistant device. For example, the second distance threshold is 200 meters. If the distance between the candidate perception-assistant device and the perception node device is 100 meters, the first condition is satisfied because the distance is less than the second distance threshold, and the candidate perception-assistant device may be permitted or agreed to participate in the perception process as a perception-assistant device.

[0118] Regarding (3) the signal quality threshold between the candidate perception auxiliary device and the perception node device.

[0119] The reference signal measurement result types used to determine signal quality include at least one of the following: Reference Signal Received Power (RSRP), Signal to Interference and Noise Ratio (SINR), Reference Signal Received Quality (RSRQ), and Reference Signal Received Path Power (RSRPP). RSRP is a parameter representing wireless signal strength, SINR is the ratio of the strength of the received useful signal to the strength of the received noise and interference, RSRQ is the ratio of RSRP to the received signal strength indication (RSSI), and RSRPP is defined as the linear average of the channel response power of the resource elements of the reference signal configured for measurement on the i-th path component, where i is a positive integer.

[0120] When the signal quality between the candidate sensing aid device and the sensing node device is greater than or equal to the signal quality threshold, the first condition is satisfied, and the candidate sensing aid device may be allowed or agreed to participate in the sensing process as a sensing aid device. For example, when the RSRP transmitted by the candidate sensing aid device is -60dBm and the signal quality threshold is -80dBm, the RSRP transmitted by the candidate sensing aid device is greater than the signal quality threshold, thus satisfying the first condition, and the candidate sensing aid device may be allowed or agreed to participate in the sensing process as a sensing aid device.

[0121] Regarding (4) the probability threshold of the perception link being the LOS path, the perception link includes the wireless link when the candidate perception auxiliary device perceives the perception target.

[0122] When the sensing link between the current candidate sensing auxiliary device, the sensing target, and the sensing node device is unobstructed, the sensing link is a LOS path. Because there is no obstruction, the signal attenuation is reduced, and the signal quality of the LOS path is better than that of the non-LOS path.

[0123] When the probability that the perceived link is an LOS path is greater than or equal to a probability threshold, the first condition is satisfied, and the candidate sensing aid device may be permitted or agreed to participate in the sensing process as a sensing aid device. For example, when the probability threshold is 80% and the probability that the perceived link is an LOS path is 90%, the probability that the perceived link is an LOS path is greater than the probability threshold, thus satisfying the first condition, and the candidate sensing aid device may be permitted or agreed to participate in the sensing process as a sensing aid device.

[0124] In some embodiments, the threshold information is a fixed value preset by the candidate perception assistance device; or,

[0125] The threshold information is a changing value dynamically determined based on the remaining power of the candidate perception auxiliary device. For example, when the remaining power of the candidate perception auxiliary device is sufficient, the distance threshold A between the candidate perception auxiliary device and the perception target is greater than the distance threshold B when the remaining power of the candidate perception auxiliary device is insufficient; or

[0126] The threshold information is a dynamically changing value determined based on the amount of computing resources of the candidate perception aid. For example, when the candidate perception aid has sufficient computing resources, the distance threshold A between the candidate perception aid and the perceived target is greater than the distance threshold B when the candidate perception aid has insufficient computing resources.

[0127] In some embodiments, the indication information also carries: a method for using the threshold information within the first condition (such as at least one of greater than, equal to, and less than), judgment input information related to the first condition (such as the distance, signal quality, probability, etc. measured by the above-mentioned candidate perception auxiliary device), and at least one of the judgment results of the candidate perception auxiliary device on whether the above-mentioned first condition is met.

[0128] In some embodiments, a candidate sensing auxiliary device receives a sensing request message sent by a sensing node device. The sensing request message is carried in a request message of the sidelink discovery process mode B. The candidate sensing auxiliary device sends a sensing feedback message to the sensing node device, the sensing feedback message carrying indication information. The sensing feedback message is carried in a response message of the sidelink discovery process mode B.

[0129] In some embodiments, the candidate sensing auxiliary device broadcasts a sensing discovery message, wherein the sensing discovery message carries indication information, wherein the sensing discovery message is carried in an announcement message of the sidelink discovery process mode A.

[0130] To sum up, the method provided in this embodiment sends indication information, which is used to indicate that the candidate perception auxiliary device serves as a perception auxiliary device participating in the perception process when the first condition is met, thereby helping the perception node device to more accurately select the perception auxiliary device and reduce unnecessary energy consumption.

[0131] FIG8 shows a flowchart of an information indication method provided by an exemplary embodiment of the present application. The method is executed by a sensing node device, and the method includes:

[0132] Step 810: Receive indication information sent by a candidate perception assistance device, where the indication information is used to instruct the candidate perception assistance device to serve as a perception assistance device participating in the perception process if a first condition is met.

[0133] The specific implementation details of step 810 refer to step 710 and will not be repeated here.

[0134] Step 820: Confirm whether the candidate perception-assisting device is a perception-assisting device based on the indication information.

[0135] If the candidate perception assistance device is determined to meet the first condition based on the indication information, the candidate perception assistance device is used as the perception assistance device;

[0136] The first condition includes at least one of the following:

[0137] (1) The distance between the candidate perception auxiliary device and the perception target is less than or equal to the first distance threshold;

[0138] (2) The distance between the candidate sensing auxiliary device and the sensing node device is less than or equal to the second distance threshold;

[0139] (3) The signal quality between the candidate sensing auxiliary device and the sensing node device is greater than or equal to the signal quality threshold;

[0140] (4) The probability that the sensing link is the LOS path is greater than or equal to the probability threshold, and the sensing link includes the wireless link when the candidate sensing auxiliary device senses the sensing target;

[0141] (5) The candidate perception auxiliary equipment is related to the current perception service.

[0142] For (1), the distance between the candidate perception auxiliary device and the perception target is less than or equal to the first distance threshold.

[0143] When the distance between the candidate sensing auxiliary device and the sensing target is less than or equal to a first distance threshold, a first condition is satisfied, and the candidate sensing auxiliary device is determined to be a sensing auxiliary device based on the indication information. The distance between the candidate sensing auxiliary device and the sensing target is measured by the candidate sensing auxiliary device and carried in the indication information and sent to the sensing node device.

[0144] Exemplarily, the first distance threshold is 100 meters. When the distance between the candidate perception assistance device and the perception target is 50 meters, it is less than the first distance threshold, which means that the first condition is met, and the candidate perception assistance device is determined to be a perception assistance device based on the indication information.

[0145] For (2), the distance between the candidate perception auxiliary device and the perception node device is less than or equal to the second distance threshold.

[0146] When the distance between the candidate sensing auxiliary device and the sensing node device is less than or equal to the second distance threshold, the first condition is met, and the candidate sensing auxiliary device is determined to be the sensing auxiliary device based on the indication information. The distance between the candidate sensing auxiliary device and the sensing node device can be measured by the sensing node device, or can be measured by the candidate sensing auxiliary device and sent to the sensing node device in the indication information.

[0147] Exemplarily, the second distance threshold is 200 meters. When the distance between the candidate perception auxiliary device and the perception node device is 100 meters, the first condition is met if it is less than the second distance threshold, and the candidate perception auxiliary device is determined to be a perception auxiliary device based on the indication information.

[0148] (3) The signal quality between the candidate perception auxiliary device and the perception node device is greater than or equal to the signal quality threshold.

[0149] Reference signal measurement result types used to determine signal quality include at least one of the following: RSRP, SINR, RSRQ, and RSRPP. RSRP is a parameter representing wireless signal strength, SINR is the ratio of the received useful signal strength to the received noise and interference strength, RSRQ is the ratio of RSRP to RSSI, and RSRPP is defined as the linear average of the channel response power of the resource elements of the reference signal configured for measurement on the i-th path component, where i is a positive integer.

[0150] If the signal quality between the candidate sensing auxiliary device and the sensing node device is greater than or equal to a signal quality threshold, the first condition is met, and the candidate sensing auxiliary device is determined to be the sensing auxiliary device based on the indication information. The signal quality between the candidate sensing auxiliary device and the sensing node device can be measured by the sensing node device, or can be measured by the candidate sensing auxiliary device and sent to the sensing node device in the indication information.

[0151] For example, when the RSRP transmitted by the candidate perception-assisted device is -60dBm and the signal quality threshold is -80dBm, the RSRP transmitted by the candidate perception-assisted device is greater than the signal quality threshold, which satisfies the first condition, and the candidate perception-assisted device is determined to be a perception-assisted device based on the indication information.

[0152] Regarding (4) the probability threshold of the perception link being the LOS path, the perception link includes the wireless link when the candidate perception auxiliary device perceives the perception target.

[0153] When the sensing link between the current candidate sensing auxiliary device, the sensing target, and the sensing node device is unobstructed, the sensing link is a LOS path. Because there is no obstruction, the signal attenuation is reduced, and the signal quality of the LOS path is better than that of the non-LOS path.

[0154] If the probability that the perception link is a LOS path is greater than or equal to a probability threshold, the first condition is met, and the candidate perception-assistant device is determined as the perception-assistant device based on the indication information. The probability that the perception link is a LOS path is measured by the candidate perception-assistant device and carried in the indication information sent to the perception node device.

[0155] Exemplarily, when the probability threshold is 80% and the probability that the perception link is a LOS path is 90%, the probability that the perception link is a LOS path is greater than the probability threshold, which satisfies the first condition, and the candidate perception auxiliary device is determined to be a perception auxiliary device based on the indication information.

[0156] Regarding (5), the candidate perception auxiliary device is related to the current perception service.

[0157] If the candidate sensing auxiliary device is related to the current sensing service, the first condition is met and the candidate sensing auxiliary device is determined to be the sensing auxiliary device based on the indication information. Whether the candidate sensing auxiliary device is related to the current sensing service is obtained by measurement by the candidate sensing auxiliary device and carried in the indication information and sent to the sensing node device.

[0158] Exemplarily, after measuring the candidate perception-assisted device, a result related to the candidate perception-assisted device and the current perception service is obtained, and the first condition is met, and the candidate perception-assisted device is determined to be the perception-assisted device based on the indication information.

[0159] In some embodiments, the sensing node device sends a sensing request message to the candidate sensing assisting device.

[0160] Among them, the perception request message is carried in the request message of the side link discovery process mode B.

[0161] The perception node device receives the perception feedback message sent by the candidate perception auxiliary device, where the perception feedback message carries indication information.

[0162] Among them, the perception feedback message is carried in the response message of the side link discovery process mode B.

[0163] In some embodiments, the sensing node device receives a sensing discovery message broadcast by a candidate sensing auxiliary device, where the sensing discovery message carries indication information.

[0164] Among them, the perception discovery message is carried in the declaration message of the side link discovery process mode A.

[0165] To sum up, the method provided in this embodiment confirms whether the candidate perception auxiliary device is a perception auxiliary device based on the indication information. The indication information is used to indicate that the candidate perception auxiliary device serves as a perception auxiliary device participating in the perception process when the first condition is met, thereby helping the perception node device to more accurately select the perception auxiliary device and reduce unnecessary energy consumption.

[0167] The candidate sensing assisted UE reports conditional assistance information to help the network select a sensing assisted UE, i.e., a sensing receiving node or a sensing transmitting node. FIG9 shows a flowchart of an information indication method provided by an exemplary embodiment of the present application. The implementation environment of the method is shown in FIG1 . The method is performed by the candidate sensing assisted UE 910 and the access network device 20 in the terminal device 10. The method includes:

[0168] Step 901: The access network device sends a perception request message.

[0169] The candidate sensing-assisted UE 910 receives a sensing request message sent by the access network device 20 and / or the AMF and / or the SF. The sensing request message can be sent via a broadcast message, a paging message, or dedicated signaling. The dedicated signaling includes at least one of the following: a Medium Access Control Control Element (MAC CE), a Radio Resource Control (RRC), or a NAS message.

[0170] The perception request message may indicate a perception type, including at least one of the following: air interface uplink perception, air interface downlink perception, terminal device echo perception, and inter-terminal device perception.

[0171] Step 902: The candidate sensing-assisted UE sends a sensing feedback message.

[0172] The perception feedback message carries indication information. The indication information is used to indicate that the candidate perception-assisted UE 910 can serve as the perception-assisted UE if a first condition is met, where the first condition includes at least one of the following:

[0173] (1) The distance between the candidate sensing assistance UE 910 and the sensing target is less than or equal to the first distance threshold;

[0174] (2) The distance between the candidate sensing assistance UE 910 and the access network device 20 is less than or equal to the second distance threshold;

[0175] (3) The signal quality between the candidate sensing assisted UE 910 and the access network device 20 is greater than or equal to the signal quality threshold;

[0176] (4) The probability that the perception link is a LOS path is greater than or equal to a probability threshold, and the perception link includes the wireless link when the candidate perception assisting UE 910 perceives the perception target.

[0177] For (1), the distance between the candidate sensing assistance UE 910 and the sensing target is less than or equal to the first distance threshold.

[0178] When the distance between the candidate sensing assistance UE 910 and the sensing target is less than or equal to the first distance threshold, the first condition is met and the candidate sensing assistance UE 910 can be used as the sensing assistance UE.

[0179] The indication information carries information including at least one of the following:

[0180] The distance between the candidate sensing assistance UE 910 and the sensing target;

[0181] First distance threshold;

[0182] The relationship between the distance between the candidate sensing assistance UE 910 and the sensing target and the first distance threshold.

[0183] For example, when the first distance threshold is 100 meters and the distance between the candidate perception assistance UE 910 and the perception target is 50 meters, the first condition is met if the distance is less than the first distance threshold, and the candidate perception assistance UE 910 can be used as a perception assistance UE.

[0184] For (2), the distance between the candidate perception assistance UE 910 and the access network device 20 is less than or equal to the second distance threshold.

[0185] When the distance between the candidate perception-assisted UE 910 and the access network device 20 is less than or equal to the second distance threshold, the first condition is met and the candidate perception-assisted UE 910 can be used as a perception-assisted UE.

[0186] The indication information carries information including at least one of the following:

[0187] the distance between the candidate sensing assistance UE 910 and the access network device 20;

[0188] Second distance threshold;

[0189] The relationship between the distance between the candidate sensing assistance UE 910 and the access network device 20 and the second distance threshold.

[0190] For example, when the second distance threshold is 200 meters and the distance between the candidate perception-assisted UE 910 and the access network device 20 is 100 meters, the first condition is met if it is less than the second distance threshold, and the candidate perception-assisted UE 910 can be used as a perception-assisted UE.

[0191] For (3), the signal quality between the candidate perception assistance UE 910 and the access network device 20 is greater than or equal to the signal quality threshold.

[0192] Reference signal measurement result types used to determine signal quality include at least one of the following: RSRP, SINR, RSRQ, and RSRPP. RSRP is a parameter representing wireless signal strength, SINR is the ratio of the received useful signal strength to the received noise and interference strength, RSRQ is the ratio of RSRP to RSSI, and RSRPP is defined as the linear average of the channel response power of the resource elements of the reference signal configured for measurement on the i-th path component, where i is a positive integer.

[0193] When the signal quality between the candidate perception-assisted UE 910 and the access network device 20 is greater than or equal to the signal quality threshold, the first condition is met and the candidate perception-assisted UE 910 can be used as the perception-assisted UE.

[0194] The indication information carries information including at least one of the following:

[0195] signal quality between the candidate sensing auxiliary UE 910 and the access network device 20;

[0196] Signal quality threshold;

[0197] The relationship between the signal quality between the candidate sensing auxiliary UE 910 and the access network device 20 and the signal quality threshold.

[0198] For example, when the RSRP transmitted by the candidate sensing assisted UE 910 is -60dBm and the signal quality threshold is -80dBm, the RSRP transmitted by the candidate sensing assisted UE 910 is greater than the signal quality threshold, which satisfies the first condition, and the candidate sensing assisted UE 910 can be used as a sensing assisted UE.

[0199] Regarding (4) the probability threshold of the perception link being the LOS path, the perception link includes the wireless link when the candidate perception-assisted UE 910 perceives the perception target.

[0200] When there is no obstruction in the sensing link between the current candidate sensing assistance UE 910, the sensing target, and then the access network device 20, the sensing link is a LOS path. Because there is no obstruction, the signal attenuation is reduced, and the signal quality of the LOS path is better than that of the non-LOS path.

[0201] When the probability that the sensing link is a LOS path is greater than or equal to the probability threshold, the first condition is met and the candidate sensing assisted UE 910 can be used as the sensing assisted UE.

[0202] The indication information carries information including at least one of the following:

[0203] The probability that the perceived link is a LOS path;

[0204] Probability threshold;

[0205] The relationship between the probability of the perceived link being an LOS path and the probability threshold value.

[0206] Exemplarily, when the probability threshold is 80% and the probability that the perception link is a LOS path is 90%, the probability that the perception link is a LOS path is greater than the probability threshold, which satisfies the first condition, and the candidate perception-assisted UE 910 can be used as a perception-assisted UE.

[0207] Step 903: The access network device confirms whether the current candidate sensing assisted UE is a sensing assisted UE participating in the sensing process.

[0208] The access network device 20 confirms whether the current candidate sensing-assisted UE 910 is a sensing-assisted UE participating in the sensing process according to the sensing feedback message, thereby performing the sensing process.

[0209] To sum up, the method provided in this embodiment confirms whether the current candidate perception-assisted UE 910 is a perception-assisted UE participating in the perception process through the access network device 20 based on the perception feedback message, thereby helping the access network device 20 to more accurately select the perception-assisted device and reduce unnecessary energy consumption overhead.

The candidate sensing assistance UEs send conditional assistance information to help the sensing service UE select an appropriate sensing assistance UE from multiple different candidate sensing assistance UEs.

The method is performed by a candidate perception-assisted UE 910 and a perception node device. In this embodiment, the perception node device is an perception-serving UE 1010 as an example. The method includes:

[0213] Step 1101: The perception service UE sends a perception request message.

[0214] The candidate perception assistance UE910 receives the perception request message sent by the perception service UE1010. The perception request message can be sent through the PC5 interface in the form of broadcast message, multicast message, dedicated signaling, etc.

[0215] The perception request message can be carried in the request message of the side link discovery process mode B.

[0216] Step 1102: The candidate sensing-assisted UE sends a sensing feedback message.

[0217] The perception feedback message is used to indicate that the candidate perception-assisted UE 910 can serve as a perception-assisted UE if the first condition is met. For specific implementation details, refer to step 902 and will not be repeated here.

[0220] To sum up, the method provided in this embodiment confirms whether the current candidate perception assistance UE 910 is the perception assistance UE participating in the perception process based on the perception feedback message through the perception service UE 1010, thereby helping the perception service UE 1010 to more accurately select the perception assistance device and reduce unnecessary energy consumption.

[0223] Step 1201: The candidate sensing assisted UE broadcasts a sensing discovery message.

[0224] The sensing discovery message carries the assistance message of the sensing node selection, which is used to indicate that the candidate sensing assisted UE 910 can be used as the sensing assisted UE if the first condition is met. For specific implementation details, please refer to step 902 and will not be repeated here.

[0225] The perception discovery message is sent in the form of a broadcast message or a multicast message, can be carried in the announcement message of the side link discovery process mode A, and is sent at a predefined discovery interval.

[0226] Step 1202: The perception service UE monitors the perception discovery message, and confirms whether the current candidate perception assistance UE 910 is a perception assistance UE participating in the perception process according to the perception discovery message.

[0227] The perception service UE 1010 monitors the perception discovery messages sent by multiple different candidate perception assistance UEs, and confirms whether the current candidate perception assistance UE 910 is the perception assistance UE participating in the perception process based on the perception discovery messages, thereby performing the perception process.

[0228] To sum up, the method provided in this embodiment confirms whether the current candidate perception assistance UE910 is a perception assistance UE participating in the perception process through the perception service UE1010 according to the perception discovery message, thereby helping the perception service UE1010 to more accurately select the perception assistance device and reduce unnecessary energy consumption.
