In the following, unless explicitly stated, resources in the frequency domain and the time domain will be used as examples of transmission resources for describing some example embodiments of the present disclosure. Note that the example embodiments of the present disclosure are equally applicable to other resources in other domains.

[0045] As mentioned above, location awareness is a fundamental aspect of wireless communication networks and will enable countless location-enabled services in different applications.

[0046] In some example embodiments, a UE may obtain its position by measuring a position reference signal (PRS). However, in some cases, PRS is not a preferred alternative for public wireless networks because PRS transmission may interrupt downlink transmission and occupy too many resource elements (REs) in a PRB. In addition, measuring PRS for position requires a complex implementation on the UE side.

[0047] In some other embodiments, the UE may obtain its location via GNSS information. However, the GNSS information is provided from a third party. Therefore, the location information provided by the UE's GNSS cannot always be trusted, as erroneous location information may be provided.

[0048] In addition, in some cases with coverage issues (e.g., the UE is indoors, moving indoors, or blocked by some blocks), GNSS signals may not be available. In these scenarios, the UE may not be able to obtain accurate GNSS information, or even be unable to achieve positioning by using GNSS. In addition, the GNSS information may be incorrect due to poor GNSS channel conditions.

[0049] In some example embodiments, in a GNSS system, access network equipment (such as a gNB) may be deployed on or separately from a satellite, and signaling may be exchanged between a UE and a satellite. For NTN, there is a long propagation delay and a long round trip time (RTT) between the UE and the satellite, for example, a maximum of 541.46 ms for a geosynchronous earth orbit (GEO) scenario, and a maximum of 25.77 ms (for 600 km) and 41.77 ms (for 1200 km) for a LEO scenario.

[0050] In addition, for the NTN LEO scenario, the satellite moves at a fast moving speed, such as 7.56 km / s. Therefore, in the NTN LEO scenario, the distance between the UE and the satellite / network is always changing. In some example embodiments, together with the satellite movement, the UE can adjust the TA based on the GNSS measurement and the received satellite ephemeris so that the uplink signal can arrive at the signal reference point with the correct signal synchronization. In general, the TA in the NTN LEO scenario may be much larger than the TA in the transport network (TN) network.

[0051] In some example embodiments, the UE reports the TA if the change in TA compared to the last reported TA is greater than a threshold value (such as 1 ms), ie, event-triggered TA reporting.

[0052] According to some example embodiments of the present disclosure, a solution for location identification and verification is provided, in which a network device can use the reported TA as auxiliary information to identify / verify the location of the UE. In particular, to ensure that the network device can identify / verify the location of the UE, unlike event-triggered TA reporting, the TA reporting process according to some example embodiments of the present disclosure is configurable. In addition, according to some example embodiments of the present disclosure, the granularity of the reported TA can be smaller, and the reported TA can be verified or adjusted by the network.

[0053] In addition, in an example embodiment, the first device may select at least one time resource from the time resources determined based on the network configuration, and perform related operations, such as reporting a first TA on the selected at least one time resource, and sending an uplink transmission based on the first TA on the corresponding selected at least one time resource.

[0054] In this solution, a first device (such as a terminal device) determines at least one time resource and determines at least one corresponding first TA to be used at the at least one time resource. Then, the first device sends at least one corresponding first TA to a second device (such as a network device) or a third device (such as a location management device). In particular, the at least one time resource is known to both the first device and the second / third device. In this way, using the at least one corresponding first TA to be used at the at least one time resource, the second / third device can identify / verify the location of the first device.

[0055] The principles and implementations of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0056] It should be noted that any section / subsection headings provided herein are not intended to be limiting. Embodiments are described throughout this document, and any type of embodiment may be included under any section / subsection. In addition, embodiments disclosed in any section / subsection may be combined in any manner with any other embodiments described in the same section / subsection and / or different sections / subsections. Example Environment

[0057] Figure 1 An example communication environment 100 is shown in which example embodiments of the present disclosure may be implemented. In the communication environment 100, a plurality of communication devices including a first device 110 and a second device 120 may communicate with each other.

[0059] In some embodiments, the communication environment 100 is an NTN network including one or more satellites. In some example embodiments, the access network equipment (such as gNB) may be deployed at the satellite. In this case, signaling may be exchanged between the first device 110 and the satellite. Alternatively, in some example embodiments, the access network equipment (such as gNB) may be deployed separately from the satellite, such as being deployed on the ground. In this case, the first device 110 may communicate with the access network equipment via a satellite. In the present disclosure, depending on the specific application scenario or requirements, either or both of the satellite or the access network equipment may be considered as the second device 120. In the present disclosure, there is no limitation in this regard.

[0060] Optionally, the communication environment 100 further includes a third device 130 and a fourth device 140. In some exemplary embodiments, the fourth device 140 may be a core network device (such as AMF), and the third device 130 may be a location management device (such as LMF).

[0061] In some example embodiments, the first device 110 may send its location to the second device 120 / the third device 130 / the fourth device 140 , and the second device 120 / the third device 130 / the fourth device 140 may verify the location of the first device 110 .

[0062] In a particular example embodiment, the second device 120 may configure / instruct the first device 110 to determine and report location-related information (such as a TA to be used at (multiple) specific time resources) so that the second device 120 can identify / verify the location of the first device 110 accordingly.

[0063] In another specific example embodiment, the third device 130 / fourth device 140 may also configure / instruct the second device 120 and / or the first device 110 to determine and report location-related information, so that the third device 130 / fourth device 140 may verify the location of the first device 110 accordingly.

[0064] It should be understood that Figure 1 The number of devices shown and their connections are for illustrative purposes only and do not imply any limitation. The communication environment 100 may include any suitable number of devices configured to implement the example embodiments of the present disclosure. Although not shown, it should be understood that one or more additional devices may be located in the cell 102, and one or more additional cells may be deployed in the communication environment 100. Note that although shown as a network device, the second device 120 may be a device other than a network device. Although shown as a terminal device, the first device 110 may be a device other than a terminal device. Although shown as a core network device, the fourth device 140 may be a device other than a core network device. Although shown as a location management device, the third device 130 may be a device other than a location management device.

[0065] In the following, for the purpose of illustration, some example embodiments are described in which the first device 110 operates as a terminal device and the second device 120 operates as a network device. However, in some example embodiments, the operations described in conjunction with the terminal device may be implemented at a network device or other device, and the operations described in conjunction with the network device may be implemented at a terminal device or other device.

[0066] In some example embodiments, if the first device 110 is a terminal device and the second device 120 is a network device, the link from the second device 120 to the first device 110 is referred to as a downlink (DL), and the link from the first device 110 to the second device 120 is referred to as an uplink (UL). In the DL, the second device 120 is a transmitting (TX) device (or transmitter), and the first device 110 is a receiving (RX) device (or receiver). In the UL, the first device 110 is a TX device (or transmitter), and the second device 120 is an RX device (or receiver).

[0067] Communications in the communication environment 100 may be implemented according to any appropriate communication protocol, including but not limited to cellular communication protocols of the first generation (1G), second generation (2G), third generation (3G), fourth generation (4G), fifth generation (5G), sixth generation (6G), etc., wireless local area network communication protocols such as Institute of Electrical and Electronics Engineers (IEEE) 802.11, and / or any other protocol currently known or developed in the future. In addition, communications may utilize any appropriate wireless communication technology, including but not limited to: code division multiple access (CDMA), frequency division multiple access (FDMA), time division multiple access (TDMA), frequency division duplex (FDD), time division duplex (TDD), multiple input multiple output (MIMO), orthogonal frequency division multiple access (OFDM), discrete Fourier transform spread OFDM (DFT-s-OFDM) and / or any other technology currently known or to be developed in the future. Working principles and example signaling for communication

[0068] According to some example embodiments of the present disclosure, in view of the high-speed movement of the second device 120 (such as a satellite) and the accuracy requirement for location identification / verification, the movement speed of the first device 110 and the RTT between the first device 110 and the second device 120 may be ignored. In addition, it is assumed that the wireless processing at the first device 110 is trustworthy and further that the location information is based on GNSS.

[0069] Reference now Figure 2 , which shows a signaling diagram 200 for communication according to some example embodiments of the present disclosure. Figure 2 As shown, the signaling diagram 200 involves a first device 110, a second device 120, and optionally a third device 130 and an optional fourth device 140. For discussion purposes, reference is made to Figure 1 Signaling diagram 200 is described.

[0070] According to some example embodiments of the present disclosure, the first device 110 provides the second device 120 / third device 130 with at least one TA to be used at (multiple) specific time resources (hereinafter referred to as at least one first TA) as auxiliary information of the first device 110. Since the (multiple) specific time resources are known to both the first device 110 and the second device 120 / third device 130, the second device 120 / third device 130 can identify / verify the location of the first device 110.

[0071] like Figure 2 As shown, the first device 110 determines 225 at least one time resource, that is, the specific time resource(s) are known to both the first device 110 and the second device 120 / third device 130. For the second device 120, similar to the first device 110, the second device 120 also determines 245 at least one time resource.

[0072] In some example embodiments, the at least one time resource may be represented as at least one system subframe or time slot. In some example embodiments, the number of the at least one time resource may be a fixed value (such as 1, 2, or 3). In some example embodiments, the at least one time resource may be periodic (such as every 1 s or less than 1 s), or the at least one time resource may have a specific pattern.

[0073] The first device 110 then determines 230 at least one corresponding first TA to be used at the at least one time resource.

[0074] In an example embodiment, the first device 110 may select at least one time resource from (multiple) time resources determined based on the network configuration, and perform (multiple) related operations, such as reporting a first TA at the selected at least one time resource and sending an uplink transmission based on the first TA at the corresponding selected at least one time resource, as will be discussed below.

[0075] As a specific embodiment, the first device 110 determines at least one corresponding first TA based on the measured GNSS information and the received satellite ephemeris information.

[0076] Afterwards, the first device 110 sends 260-1 at least one corresponding first TA to the second device 120. In a specific example embodiment, the first device 110 collects the corresponding first TAs at at least the last time resource of the time resource. Then, the first device 110 reports all collected / determined first TAs in one message. In some example embodiments, the reporting time can be configured by the second device 120.

[0077] In some example embodiments, the second device 120 may determine 265 location information for the first device 110 based at least in part on one or more of the at least one corresponding first TA.

[0078] How the second device 120 determines the location information of the first device 110 will refer to Figure 3A and Figure 3B Let's discuss.

[0079] refer to Figure 3A , which shows an example 300 for determining location information. In general, each TA may correspond to a distance between the second device 120 and the first device 110. Therefore, for a specific TA, the second device 120 may determine a circle on the ground (such as circles 310-1, 310-2, and 310-3). A circle refers to a set of possible locations of the first device 110. Therefore, the intersection of multiple circles (such as three circles) may be considered as the location of the first device 110.

[0080] As described above, each first TA corresponds to one time resource. In a specific example embodiment, the second device 120 may use one TA to determine a circle, and the circle may be used to verify the location of the first device 110. Alternatively, in another specific example embodiment, two or more first TAs (such as 3) to be used at different time resources may be used to identify the location of the first device 110. Specifically, the circle corresponding to the first TA is used to identify an intersection, which may be considered as the location of the first device 110, such as Figure 3A shown.

[0081] In summary, each reported first TA to be used at a specific time resource (such as at least one system subframe or time slot) will indicate a circle that the first device 110 can be located at at the specific time resource. In addition, two or more (such as 3) first TAs to be used at different time resources can make the estimated position of the first device 110 more accurate.

[0082] refer to Figure 3B , which shows another example 350 for determining location information. Figure 3B As shown, the area of ​​arrival (AoA) of the first device 110 and the circle corresponding to the first TA may also identify an intersection, which may be considered as the location of the first device 110. Therefore, in some example embodiments, the second device 120 obtains the AoA of the first device 110, and determines the location information of the first device 110 based on the AoA and the reported first TA.

[0083] In summary, the first TA and the estimated uplink AoA at the same time resource may identify the exact point of the circle (ie, the location of the first device 110 ).

[0084] In some example embodiments, in order to make the estimated location of the first device 110 more accurate, the granularity of the first TA may be finer. Specifically, in some example embodiments, the first granularity of the first TA is finer than the second granularity of the second TA to be used at other time resources that are not the at least one time resource. That is, in order to assist in the verification of the location, the first TA may have a finer / smaller granularity than the normal uplink TA report.

[0085] In some example embodiments, the first granularity of the first TA may be less than a threshold value (such as 1 ms). Alternatively, the first granularity of the first TA may be a Tc / Ts level.

[0086] Additionally, considering that the reported first TA is determined by the first device 110 , which may not be accurate enough, the first device 110 may also send an uplink transmission based on the measured first TA so that the second device 120 may adjust the reported first TA.

[0087] like Figure 2 As shown, the first device 110 sends 250 at least one corresponding uplink transmission on at least one time resource based on at least one first TA. In some example embodiments, the second device 120 may determine 255 at least one corresponding time error based on the at least one corresponding uplink transmission and the uplink transmission timing. Since the uplink transmission is sent based on the first TA, the corresponding time error may be used to evaluate and adjust the corresponding first TA. In some example embodiments, the second device 120 may determine at least one corresponding third TA by adjusting at least one corresponding first TA according to the at least one corresponding time error. The third TA has a higher accuracy than the first TA.

[0088] Then, the second device 120 can determine the location information of the first device 110 based on the at least one corresponding third TA. In this way, the estimated location of the first device 110 is more accurate.

[0089] For a better understanding, now refer to Figure 3A and Figure 3B .exist Figure 3A and Figure 3B In a specific example embodiment, the second device 120 may determine a circle (such as circles 310-1, 310-2, and 310-3) by using the first TA and the corresponding time error (or third TA) at the same time resource.

[0090] In some example embodiments, in order to enable the second device 120 to obtain more accurate (multiple) time errors, in some example embodiments, the first transmission density of the uplink transmission is higher than the second transmission density of the second uplink transmission on other time resources that are not the at least one time resource. That is, at each time resource, more uplink signals are sent. That is, in order to assist in the verification of the position, the uplink signal on the at least one time resource can be sent more frequently.

[0091] In addition, in some example embodiments, the uplink transmission of at least one corresponding uplink transmission is at least one of the following: transmission of an uplink reference signal (RS) (such as a sounding reference signal SRS), transmission of a physical uplink shared channel (PUSCH), or transmission of a physical uplink control channel (PUCCH). In a specific example embodiment, the RS may be a higher density RS sent in a time resource. In a specific example embodiment, the uplink transmissions sent on at least the time resource have the same uplink transmission type. Alternatively, in another specific example embodiment, a first type of uplink transmission (such as PUCCH) is sent on a first time resource, and a different second type of uplink transmission (such as SRS) is sent in a second time resource. Alternatively, in another specific example embodiment, more than one type of uplink transmission is sent on a time resource. In this way, uplink transmissions on at least one time resource can be performed more flexibly.

[0092] In some example embodiments, at least one of the following parameters may be predefined: at least one time resource, the number of at least one time resource, the period of at least one time resource, the mode of at least one time resource, the first granularity of at least one TA, or the first transmission density. As an example, at least one of the above parameters may be predefined by a communication organization (such as 3GPP), or by a network operator or service provider. In this way, at least one of the above parameters may be determined as a default configuration, and no additional signaling exchange is required.

[0093] Alternatively, in some example embodiments, at least one of the above parameters may be configured dynamically or semi-statically. Figure 2 As shown, the second device 120 sends 222 a first configuration indicating at least one of the above parameters to the first device 110. In this way, the second device 120 can trigger the first device to send auxiliary information (ie, (multiple) first TAs) and optional uplink transmissions on demand.

[0094] In an example embodiment, the first device 110 may select at least one time resource from (multiple) time resources determined based on the network configuration, and perform (multiple) related operations, such as reporting a first TA on the selected at least one time resource, and sending an uplink transmission based on the first TA on the corresponding selected at least one time resource.

[0095] Furthermore, in some embodiments, the selected at least one time resource may be a subset of the time resource(s) configured by the network configuration.

[0096] In addition to configuring the above parameters, the second device 120 may also enable or disable the reporting process. In some example embodiments, the second device 120 may send an instruction instructing the first device 110 to enable or disable at least one of the following: sending at least one corresponding first TA; sending at least one corresponding first TA having a first granularity; sending at least one corresponding uplink transmission on at least one time resource; sending at least one corresponding uplink transmission at a first transmission density on at least one time resource; or Reports assistance information for location verification / identification.

[0097] In this way, introducing too much resource consumption for location verification / identification is avoided.

[0098] As described above, the signaling diagram 200 may also involve the third device 130 and / or the fourth device 140. In this case, the fourth device 140 and / or the third device 130 as location management devices may also trigger location verification / identification, which will be discussed in detail below.

[0099] In some example embodiments, fourth device 140 and / or third device 130 triggers first device 110 to report a first TA (with a first granularity) to be used at at least one time resource, and optionally to send (multiple) uplink transmissions (at a first transmission density) on at least one time resource. At the same time, fourth device 140 and / or third device 130 also triggers second device 120 to receive (multiple) uplink transmissions (at a first transmission density) on at least one time resource, and further determines and reports corresponding (multiple) time errors.

[0100] In some example embodiments, the third device 130 obtains the location information of the first device 110. As a specific example embodiment, the first device 110 performs registration in a super national NTN cell coverage area. Figure 2In a specific example of , the first device 110 performs 205 a registration process to the fourth device 140 (such as, AMF). Specifically, the first device 110 sends a registration message to the second device 120, wherein the registration message includes location information (such as, GNSS location) of the first device 110. The second device 120 derives tracking area identification (TAI) information based on the location information of the first device 110, wherein the TAI information includes a mobile network code (MNC) and a mobile country code (MCC). Then, the second device 120 can send the location information, TCI, MNC and / or MCC of the first device 110 to the fourth device 140.

[0101] exist Figure 2 In a specific example, the fourth device 140 may send 210 the location information of the first device 110 to the third device 130 so that the location information can be verified by the third device 130. In addition, in some example embodiments, the TCI, MNC, and / or MCC may also be sent to the third device 130 together with the location information. As a specific example embodiment, the fourth device 140 sends the location information and the TAI to the third device 130 in a field of Nlmf_Location_DetermineLocation.

[0102] In some example embodiments, third device 130 determines whether to verify the location of first device 110, such as whether to verify the MNC and / or the MCC. If so, third device 130 generates a second configuration to be used by first device 110 and a third configuration to be used by second device 130. Similar to the first configuration, each of the second configuration and the third configuration may indicate at least one of the following: at least one time resource, the number of at least one time resource, the period of at least one time resource, the mode of at least one time resource, the first granularity of at least one TA, or the first transmission density.

[0103] In a specific example embodiment, the third device 130 initiates an LTE Positioning Protocol (LPP) session with the first device 110. Specifically, the third device 130 sends 220 RequestLocationInformation to the first device 110, wherein the RequestLocationInformation triggers the first device 110 to perform a first measurement (such as a GNSS measurement) and / or a second measurement (such as determining (multiple) first TAs and sending (multiple) uplink transmissions on at least one time resource). In addition, the RequestLocationInformation may also indicate an association between the first measurement and the second measurement. In addition, the RequestLocationInformation also indicates at least one of the following: at least one time resource, the number of at least one time resource, the period of at least one time resource, the pattern of at least one time resource, the first granularity of at least one TA, or the first transmission density.

[0104] In some example embodiments, the second configuration is sent as a non-access stratum (NAS) message. In view of this, after receiving the second configuration, there may be some internal interactions between different layers of the first device 110, as described below.

[0105] In some example embodiments, the NAS layer of the first device 110 receives the second configuration from the third device 130. Then, the NAS layer triggers the first device 110 to determine at least one corresponding first TA based on the second configuration. Figure 2 In a specific example, the NAS layer requests 225-1 a first measurement (such as, a GNSS measurement) and / or a second measurement (such as, determining (multiple) first TAs and sending (multiple) uplink transmissions on at least one time resource), and then triggers 225-2 an access stratum (AS) layer of the first device 110 to perform the first measurement and / or the second measurement.

[0106] Thus, the AS layer may determine 230-1 at least one corresponding first TA and optionally initiate 235 an uplink transmission on at least one time resource.

[0107] As a specific embodiment, the first device 110 determines at least one corresponding first TA based on the measured GNSS information and the received satellite ephemeris information.

[0108] How to determine at least one corresponding first TA and how to send uplink transmission on at least one time resource have been fully discussed previously. For the sake of brevity only, the same or similar contents are omitted here.

[0109] In some example embodiments, the AS layer sends 260-2 at least one corresponding first TA to the NAS layer of the first device 110, and the NAS layer may send 275 at least one corresponding first TA to the third device 130 via a NAS message (such as, including the at least one corresponding first TA in a ProvideLocationInformation field of the NAS message).

[0110] In addition, as described below, the coordination operation is also performed at the second device 120. Specifically, the third device 130 sends 220 a third configuration to the second device 120. Similar to the first configuration, the third configuration indicates at least one of the following: at least one time resource, the number of at least one time resource, the period of at least one time resource, the mode of at least one time resource, the first granularity of at least one TA, or the first transmission density.

[0111] How to obtain at least one corresponding time error and at least one corresponding third TA has been fully discussed previously. For the sake of brevity only, the same or similar contents are omitted here.

[0112] Additionally, in some embodiments, the second device 120 sends 270 to the third device 130 at least one of the following: at least one corresponding time error, at least one corresponding third TA, or at least one corresponding first TA received from the first device 110 .

[0113] According to the above process, the third device 130 may collect relevant information for verifying the location of the first device 110 (with or without comparison to the location reported by the first device 110). In some example embodiments, the third device 130 verifies 280 at least one corresponding first TA (reported by the first device 110) based on at least one corresponding third TA (reported by the second device 120). Alternatively or additionally, the third device 130 verifies 290 the location information of the first device 110 (such as the reported GNSS location of the first device 110) based on at least one of the following: at least one corresponding time error, at least one corresponding first TA, or at least one corresponding third TA.

[0114] In some embodiments, the verification result may be provided 290 to the fourth device 140. Based on the verification result, the fourth device 140 may determine 295 whether to continue or reject the registration message of the first device 110.

[0115] According to the above process, the location of the first device 110 can be verified / identified. In addition, according to some exemplary embodiments of the present disclosure, the second device 120 / the third device 130 / the fourth device 140 can more accurately verify / identify the location of the first device 110 based on the reported auxiliary information (such as (multiple) first TAs) from the first device 110 and the estimated information of the same / similar time resources estimated by the second device (such as time error, third TA, and AoA).

[0116] For better understanding only, reference will be made to Figure 4 Describing some specific example embodiments, Figure 4 FIG. 4 is a flow chart showing a process 400 for sending auxiliary information for identifying / verifying the location of the first device 110. It should be understood that referring to FIG. Figure 4 Specific example embodiments are described for purposes of illustration only, and no limitations are implied.

[0117] At block 410, the first device 110 sends an uplink transmission at a second transmission density, ie, a normal uplink transmission.

[0118] At block 420, first device 110 receives a second / third configuration from second device 120 or third device 130, wherein the second / third configuration indicates at least one time resource. In some example embodiments, second device 120 / third device 130 configures first device 110 with at least one time resource, such as at least one SFN time.

[0119] In some example embodiments, second device 120 / third device 130 configures at least one time resource (such as, one or more system frame numbers SFNs) to first device 110, and also instructs first device 110 to collect temporary fine-grained TA information (i.e., (multiple) first TAs) to be used at the at least one time resource.

[0120] At block 430 , the first device 110 determines whether at least one time resource arrives.

[0121] If yes, then at block 440, the first device 110 sends an uplink transmission at a first transmission density, and sends a first TA of a first granularity at block 450. Specifically, the first device 110 determines a first TA to be used at each time resource, and sends an uplink transmission at each time resource based on the determined first TA.

[0122] In some example embodiments, the first granularity may be Tc or Ts level (different from / smaller than the granularity used for NTN reporting as normal NTN processing, such as less than 1 ms). In addition, the first granularity may be used only during the location verification / identification process. That is, after the location verification / identification process, the granularity will change back to the second granularity (i.e., normal granularity).

[0123] In some example embodiments, uplink transmissions on each time resource are sent at a first transmission density (different from / higher than the normal transmission density). In some example embodiments, the first transmission density refers to a high density in the time domain and / or frequency domain. In addition, the first transmission density may be used only during the location verification / identification process. That is, after the location verification / identification process, the transmission density will return to the normal granularity.

[0124] Furthermore, after receiving an uplink transmission sent by the first device 110 based on the determined first TA, the second device 120 may obtain a corresponding time error corresponding to each first TA, wherein the time error corresponds to the same time resource as the first TA.

[0125] In some example embodiments, based on the reported first TA and the time error on the same / similar time resource, the second device 120 may identify a circle on the ground (eg, Figure 3A ), that is, a set of possible locations of the first device 110. In addition, an intersection of circles (such as three circles) may be identified as the location of the first device 110.

[0126] Alternatively, in some example embodiments, the second device 120 obtains the AoA of the first device 110 for a specific time resource (such as an uplink SFN time), and then the second device 120 may identify the position of the first device 110 on the circle determined based on the specific first / third TA (such as Figure 3B shown).

[0127] In some example embodiments, if the first device 110 has reported its location, the second device 120 may further verify the location of the first device 110 .

[0128] It should be understood that the above discussion about the second device 120 is also applicable to the third device 130 and the fourth device 140. For the sake of brevity only, the same or similar contents are omitted here.
