Power and time delay profile reporting for device positioning.

Abstract

Techniques are provided for a device to report positioning-related information to a network entity. In one example, the device receives signaling information from the network entity. The signaling information indicates one or more parameters for a report regarding a reference signal transmitted by a base station. The device also receives multiple propagations of the reference signal upon transmission of the reference signal by the base station. Based on the signaling information, the device generates a report, the report including a power and a time delay for each propagation of the reference signal. The device transmits the report to the network entity, and the location of the device is determined by the network entity based on the report.

Description

[Background technology] 【0001】 Determining the location of a mobile electronic device using a cellular network can involve using signaling between the device and the cellular network's base stations. According to some techniques, round-trip time (RTT) measurements may be performed to determine the distance between the device and the base station, and the device's location can be determined from these measurements. However, these measurements can be inaccurate due to multipath propagation. [Overview of the project] [Means for solving the problem] 【0002】 The technique described herein enables device positioning by using power delay profile reports. In one example, the device sends a report showing the power and time delay profiles for each reference signal received by the device from a base station. The report may be received by a network entity such as a base station or a location server. The network entity then selects a specific reference signal for each base station, if any, and estimates the device's location based on RTT measurements for the selected reference signal. Furthermore, the location estimation may be accompanied by other parameters such as transmitted beam information and sensor information (e.g., camera information and radar information). The parameters and report are input to a fusion algorithm that generates the location estimation. 【0003】 An exemplary method for reporting positioning-related information to a network entity as provided in this disclosure may include the step of receiving signaling information indicating one or more parameters for reporting a reference signal, wherein the one or more parameters identify one or more base stations. The method may also include the step of determining power and time delay profiles for one or more reference signals received from one or more base stations based on the signaling information, wherein the power and time delay profile for each of the one or more reference signals includes power and time delay information for each of the one or more propagating signals corresponding to each of the reference signals. The method may also include the step of sending a report to a network entity, wherein the report includes power and time delay profiles. 【0004】 An exemplary method for positioning a device as provided in this disclosure may include the step of sending signaling information to the device, wherein the signaling information indicates one or more parameters for reporting a reference signal.

The method may also include the step of determining the location of the device based on the report. 【0005】 An exemplary device for reporting positioning-related information to a network entity as disclosed herein comprises a transceiver, one or more memories, and one or more processors communicatively coupled to the transceiver and one or more memories, wherein one or more processors receive signaling information indicating one or more parameters for reporting about a reference signal, the one or more parameters may be configured to identify one or more base stations. One or more processing units may further determine, based on the signaling information, power and time delay profiles for one or more reference signals received from one or more base stations via the transceiver, the power and time delay profiles for each of the one or more reference signals may be configured to include power and time delay information for each of the one or more propagating signals corresponding to each of the respective reference signals. One or more processing units may further send reports to a network entity via the transceiver, the reports may include power and time delay profiles. 【0006】 An exemplary network entity for positioning a device according to this disclosure comprises a transceiver, one or more memories, and one or more processors communicatively coupled to the transceiver and one or more memories, the one or more processors may be configured to send signaling information to the device via the transceiver, the signaling information indicating one or more parameters for reporting about a reference signal. One or more processing units may further be configured to receive reports from the device based on the signaling information, the reports including power and time delay profiles for one or more reference signals received by the device from one or more base stations, the power and time delay profiles for each of the one or more reference signals including power and time delay information for each of the one or more propagating signals corresponding to each of the respective reference signals. One or more processing units may further be configured to determine the location of the device based on the reports. 【0007】 This summary is not intended to identify the main or essential features of the claimed subject matter, nor is it intended to be used alone to determine the scope of the claimed subject matter.

[Modes for carrying out the invention] 【0009】 According to several exemplary implementations, similar reference symbols in various drawings refer to the same element. In addition, multiple instances of an element can be indicated by following the first digit of the element with a letter or hyphen and a second digit. For example, multiple instances of element 110 may be indicated as 110-1, 110-2, 110-3, and so on. When referring to such an element using only the first digit, any instance of that element should be understood (for example, element 110 in the previous example would refer to elements 110-1, 110-2, and 110-3). 【0010】 The following description covers several implementations for the purpose of illustrating inventive aspects of various embodiments. However, those skilled in the art will readily recognize that the teachings herein can be applied in numerous different ways. The implementations described include the IEEE 802.11 standard (including the standard identified as Wi-Fi® technology), Bluetooth® standard, Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Global System for Mobile Communications (GSM), GSM / General-Purpose Packet Radio Service (GPRS), Enhanced Data GSM Environment (EDGE), Terrestrial Infrastructure Radio (TETRA), Wideband CDMA (W-CDMA), Evolution Data Optimized (EV-DO), 1xEV-DO, EV-DO Rev A, EV-DO Rev B. It can be implemented in any device, system, or network capable of transmitting and receiving radio frequency (RF) signals in any communication standard such as High Speed ​​Packet Data (HRPD), High Speed ​​Packet Access (HSPA), High Speed ​​Downlink Packet Access (HSDPA), High Speed ​​Uplink Packet Access (HSUPA), Advanced High Speed ​​Packet Access (HSPA+), Long-Term Evolution (LTE), or Advanced Mobile Phone Systems (AMPS), or other known signals used for communication within wireless, cellular, or Internet of Things (IoT) networks, such as systems utilizing 3G, 4G, 5G, 6G technologies, or further implementations thereof. 【0011】 As used herein, “RF signal” includes electromagnetic waves that carry information through the space between a transmitter (or transmitting device) and a receiver (or receiving device). As used herein, a transmitter may transmit a single “RF signal” or multiple “RF signals” to a receiver. However, due to the propagation characteristics of RF signals through multipath channels, a receiver may receive multiple “RF signals” corresponding to each transmitted RF signal. The same transmitted RF signal on different paths between the transmitter and receiver is sometimes called a “multipath” RF signal. 【0012】 Additionally, references to "reference signal", "positioning reference signal", "reference signal for positioning", etc. may be used to refer to signals used for positioning of a user equipment (UE). As will be described in more detail herein, such signals may include any of various signal types, but may not necessarily be limited to positioning reference signals (PRS) defined in the relevant wireless standards. 【0013】 Next, some exemplary embodiments will be described with respect to the accompanying drawings that form a part of this specification. Specific embodiments in which one or more aspects of the present disclosure may be implemented are described below, but other embodiments may be used and various modifications may be made without departing from the scope of the present disclosure. 【0014】 For clarity of explanation, various embodiments of the present disclosure are described with respect to a UE such as a mobile phone. However, the embodiments are not limited as such and are equally applicable to any other type of device. Generally, a device may be connected to a cellular network and a reference signal may be transmitted from the cellular network to the device. Measurements of the reference signal are performed to determine the position of the device. 【0015】 The 5th generation (5G) new radio (NR) is a wireless radio frequency (RF) interface standardized by the 3rd Generation Partnership Project (3GPP (registered trademark)). 5G NR is prepared to provide enhancements over previous generation (Long Term Evolution (LTE)) technologies such as significantly faster and more responsive mobile broadband, improved conductivity through IoT devices, etc. Additionally, 5G NR enables new positioning techniques for UEs, including angle of arrival (AoA) / angle of departure (AoD) positioning, UE-based positioning, and multi-cell round trip time (RTT) positioning. With respect to RTT positioning, this involves taking RTT measurements between a UE and multiple base stations. 【0016】 FIG. 1 is a diagram showing an example of a terrestrial positioning system 100 according to an embodiment. Here, the terrestrial positioning system 100 includes a plurality of cellular transceivers, or base stations 110-1, 110-2, and 110-3 (generally referred to as base stations 110 herein), which are used to determine the location of the UE 120 (e.g., in geographical coordinates). Both the base stations 110 and / or the UE 120 may be communicatively coupled to the location server 130 via a wide area network (WAN) 140, which may include a network of cellular carriers, as well as other data communication networks, as will be described in more detail below. (The solid arrows between the components indicate communication links.) The UE 120 may be communicatively coupled to the WAN 140 via wireless communication with one or more of the base stations 110, but the UE 120 may have additional or alternative communication links in addition to the WAN 140 as shown. 【0017】 FIG. 1 provides a generalized illustration of various components, and note that any or all of the components may be used as appropriate, and each of the components may be replicated or omitted as needed. Specifically, although one UE 120 is shown, it will be understood that many UEs (e.g., hundreds, thousands, millions, etc.) may utilize the terrestrial positioning system 100. Similarly, the terrestrial positioning system 100 may include more or fewer base stations 110, location servers 130, and / or other components. The illustrated communication links that communicatively connect the various components in the terrestrial positioning system 100 may include data and signaling connections that may include additional (intermediate) components, direct or indirect physical (wired) and / or wireless connections, and / or additional networks. Further, the components may be rearranged, combined, separated, replaced, and / or omitted according to the desired functionality. 【0018】 As used herein, UE120 may be an electronic device and may be referred to as a device, mobile device, wireless device, mobile terminal, terminal, wireless terminal, mobile station (MS), Secure User Plane Location (SUPL) enabled terminal (SET), or by any other name. Furthermore, UE120 may be a cell phone, smartphone, laptop, tablet, personal digital assistant (PDA), wearable device (e.g., smartwatch, tracking device, or any other portable or mobile device). In some cases, UE120 may be part of some other entity, for example, a chipset supporting a modem integrated into some larger mobile entity such as a vehicle, drone, package, transport, or robotic device. Generally, but not necessarily, UE120 may support wireless communications using one or more radio access technologies (RATs) (e.g., in addition to 5G NR), such as GSM, CDMA, W-CDMA, LTE, HRPD, IEEE 802.11 Wi-Fi, Bluetooth® (BT), and Global Interoperability for Microwave Access (WiMAX). UE120 may also support wireless communications using a wireless local area network (WLAN) that can connect to other networks (e.g., the Internet). WAN140 may include such wireless communications networks and / or technologies. 【0019】 UE120 may include a single entity or multiple entities in a personal area network, for example, where the user may employ audio, video and / or data I / O devices and / or body sensors, and separate wireline or wireless modems. The location estimate of UE120 may be referred to as location, location estimate, location fix, fix, position, location estimate or location fix (such terms are used interchangeably herein), and may be geodetic, and thus provide the location coordinates of UE120 (e.g., latitude and longitude), and the location coordinates may or may not include an elevation component (e.g., elevation, height or depth from the ground, floor or underground). Alternatively, the location of UE120 may be represented as a city location (e.g., as a mailing address or designation of some point or small area within a building, such as a particular room or floor). The location of a UE120 may also be expressed as an area or volume (defined either geodesically or in urban form) where the UE120 is expected to be located with some probability or level of confidence (e.g., 67%, 165%). The location of a UE120 may further be a relative location including distance and direction or relative X, Y (and optionally, Z) coordinates defined with respect to some origin in a known location which may be defined, for example, geodesically, in civic terminology, or by referring to a point, area, or volume shown on a map, floor plan, or building plan. In the descriptions contained herein, the use of the term location may include any of these variations unless otherwise specified. When calculating the location of a UE, it is common to obtain local X, Y, and possibly Z coordinate values ​​and then, if necessary, convert the local coordinates to absolute coordinates (e.g., latitude, longitude, and altitude above or below mean sea level). 【0020】 As stated, depending on the desired functionality, WAN140 may include any of various wireless and / or wireline communication networks. WAN140 may include any combination of, for example, public and / or private networks, local and / or wide area networks, etc. Furthermore, WAN140 may utilize one or more wired and / or wireless communication technologies. In some embodiments, WAN140 may include, for example, cellular or other mobile networks, WLANs, wireless wide area networks (WWANs), and / or the internet. Specific examples of WAN140 include 5G NR networks, LTE networks, Wi-Fi WLANs, etc. WAN140 may also include two or more networks and / or network types. 【0021】 The base station 110 may include nodes in the cellular network, which may enable the UE 120 to communicate wirelessly with other devices linked to the WAN 140. The base station 110 may have a known location and therefore may be used for positioning as described herein. As will be described in more detail below, the technique is not necessarily limited to fixed base stations (i.e., base stations with fixed locations), but may include mobile base stations and even other UE 120s. In the case of 5G NR, the base station 110 may include next-generation node B (gNB). The WAN 140, including additional or alternative RATs, may include base station 110 including node B, advanced node B (enode B or eNB), base station transceiver station (BTS), radio base station (RBS), NR node B (gNB), next-generation eNB (ng-eNB), Wi-Fi AP, and / or Bluetooth® AP. Thus, the UE 120 can send and receive information to and from network-connected devices such as a location server 130 by accessing the WAN 140. Furthermore, as mentioned, UE120 can access WAN140 via base station 110. Base station 110 and / or base station antennas are sometimes referred to as transmit / receive points (TRPs). 【0022】 The location server 130 may include a server and / or other computing device configured to determine the estimated location of the UE 120 and / or provide the UE 120 with data (e.g., “support data”) to facilitate location determination. According to some embodiments, the location server 130 may also include a Secure User Plane Location (SUPL) Location Platform (SLP), which can support the SUPL User Plane (UP) Location Solution as defined by the Open Mobile Alliance (OMA) and can support location services for the UE 120 based on subscription information about the UE 120 stored in the location server 130. The location server 130 may also include an Extended Serving Mobile Location Center (E-SMLC) that supports the location of the UE 120 using a Control Plane (CP) Location Solution for LTE radio access by the UE 120. The location server 130 may further include a Location Management Function (LMF) that supports the location of the UE 120 using a Control Plane (CP) Location Solution for 5G or NR radio access by the UE 120. In the CP location solution, signaling for controlling and managing the location of UE120 can be exchanged between elements of WAN140 and with UE120 as signaling from the perspective of WAN140 using existing network interfaces and protocols. In the UP location solution, signaling for controlling and managing the location of UE120 can be exchanged between location server 130 and UE120 as data from the perspective of WAN140 (for example, data transported using Internet Protocol (IP) and / or Transmission Control Protocol (TCP)). 【0023】 It can be further noted that in some embodiments of the ground positioning system 100, the location server 130 may be performed by the UE 120 itself and / or incorporated into the UE 120 itself. That is, in the embodiments described herein, the functions of the location server 130 may be performed by the UE 120. Thus, in such cases, communication between the UE and the location server may take place between the hardware and / or software components of the UE 120. Similarly, the functions of the location server 130 described herein may be performed by a base station 110 or other device communicatively coupled to the ground positioning system 100. 【0024】 Additionally, the positioning of UE120 can be "UE-based" or "network-based". UE-based positioning involves UE120 determining its own location, which can be facilitated by information provided to UE120 by the network (e.g., location server 130 and / or base station 110). Network-based positioning involves the network (e.g., location server 130) determining the location of the UE, which can be facilitated by information provided to the network by UE120. The techniques for RTT-based positioning provided herein may be applied to either UE-based or network-based positioning. For example, in the case of UE-based positioning, an RTT measurement may be initiated by UE120 and / or the RTT measurement may be communicated to UE120, and UE120 can determine its own location if the location of base station 110 from which the RTT measurement was taken is provided. In the case of network-based positioning, RTT measurements may be initiated by one or more base stations 110 and / or RTT measurements may be communicated to one or more base stations 110, which may send the measurements to a location server 130, which can then determine the location of the UE 120. 【0025】 The ground positioning system 100 can determine the location of UE120 by utilizing both downlink (DL) information transmitted by base station 110 and uplink (UL) information transmitted by UE120. As will be described in more detail below, some positioning methods can determine the location of UE120 using RTT by determining one or more distances 150 from base station 110 and then determining the location of UE120 using multilateration or a similar algorithm. In multilateration, for example, distances 150-1, 150-2, and 150-3 follow circles 160-1, 160-2, and 160-3 respectively (only those parts are shown in Figure 1), and the location of UE120 may be determined as the intersection of these circles 160. Alternative positioning methods may use a combination of distance information and angular information (e.g., AoA, AoD) from one or more RTT measurements. A positioning method that uses RTT measurements along with angular information may allow the location of the UE120 to be determined using a single base station 110. 【0026】 Figure 2 is a multipath diagram showing an example of reference signal propagation according to one embodiment. In particular, in this example, multiple base stations 210 communicate with a UE 220. Each base station 210 sends a reference signal to the UE 220 on which an RTT measurement may be performed. An RTT measurement of the reference signal is performed by the UE 220 to determine the location of the UE 220. However, if different physical objects exist in the environment, multipath propagation may occur, in which a single reference signal transmitted by a base station may propagate along multiple paths. As used herein, the term “propagated signal” refers to the portion of a signal that propagates along a particular propagation path. Therefore, due to multipath propagation, the UE 220 may receive multiple propagated signals resulting from different portions of a single reference signal propagating along each of the different propagation paths. In other words, a propagated signal is the reference signal received from a base station along a particular propagation path. UE220 may receive multiple propagation signals from a base station, where these propagation signals correspond to the same transmission of a reference signal by the base station, and each propagation signal is received along a different propagation path. One propagation path may correspond to a line-of-sight transmission from the base station to UE220, resulting in UE220 receiving a first propagation signal (or equivalently, a first reference signal) from the base station. Another propagation path may correspond to a reflected path, where UE220 receives a second propagation signal (or equivalently, a second reference signal), which is a reflection of the first reference signal by an object between UE220 and the base station. Multipath propagation can degrade the accuracy of UE positioning based on RTT measurements. Accuracy in multipath environments can be improved by selecting specific propagation signals (e.g., propagation signals corresponding to line-of-sight transmissions of the reference signal rather than reflected transmissions). 【0027】 In the example in Figure 2, three base stations 210-1, 210-2, and 210-3 are communicating with UE220. Four reflectors 230-1, 230-2, 230-3, and 230-4 may cause reflections of the transmitted reference signal. The source from which the propagating signal is received by UE220 may be called a tap, where the propagating signal is a portion of the reference signal propagating along a line-of-sight path or a reflected reference signal along a non-line-of-sight path. Figure 2 shows a physical environment with a specific number of base stations and reflectors, but other configurations of the physical environment are possible (for example, the physical environment may include a different number of base stations and / or reflectors). 【0028】 Base station 210-1 transmits a reference signal to UE220. The reference signal may be, for example, a demodulated reference signal (DMRS), a phase-tracking reference signal (PTRS), a sounding reference signal (SRS), or a channel status information reference signal (CSI-RS). In the example in Figure 2, three propagating signals are received by UE220 and correspond to the transmitted reference signals. The first propagating signal is received along the line-of-sight path 212 between base station 210-1 and UE220. Base station 210-1 is the tap of this first propagating signal. The second propagating signal is received along the reflection path 214-1 (non-line-of-sight path) by reflection from the first reflector 230-1 to UE220. The first reflector 230-1 is the tap of the second propagating signal. Similarly, the third propagating signal is received along another reflection path 214-2 (also a non-line-of-sight path) by reflection from the second reflection source 230-2 to UE220. The second reflection source 230-2 is the tap for the third propagating signal. When RTT measurements are performed against a reference signal, a decision is made regarding which of the three propagating signals to use. Selecting the first propagating signal (e.g., the one corresponding to line-of-sight path 212, as indicated by the checkmark) and not selecting the other two propagating signals (e.g., the ones corresponding to reflection paths 214-1 and 214-2, as indicated by the two X marks) yields the best possible accuracy. 【0029】 Similarly, base station 210-2 transmits a reference signal to UE220. UE220 then receives three propagating signals: one along the line-of-sight path between base station 210-2 and UE220, another along the reflection path involving the first reflector 230-1, and an additional propagation signal along the reflection path involving the third reflector 230-3. Again, when multilateration is used, the accuracy of UE220's location estimation is improved by performing RTT measurements of the propagation signals along the line-of-sight path (indicated by the checkmark) rather than the propagation signals from non-line-of-sight paths (indicated by the two X marks). 【0030】 Furthermore, base station 210-3 transmits a reference signal to UE220. However, here, due to the presence of a fourth reflector 230-4 in between, there is no line-of-sight path between base station 210-3 and UE220. Instead, UE220 receives two propagating signals: one along the reflection path involving the second reflector 230-2, and another along the reflection path involving the third reflector 230-3. When multilateration is used, the accuracy of the UE's location estimation can be improved by selecting a better propagating signal (as indicated by a checkmark). (A propagating signal that is not selected is indicated by an X.) Alternatively, since both propagating signals from base station 210-3 are reflections rather than line-of-sight transmissions of the reference signal, multilateration may filter out one or both of the two propagating signals (for example, the RTT measurement for the reference signal sent by base station 210-3 may be ignored). 【0031】 In one example, to assist in the selection of a propagating signal for each transmitted reference signal, the UE220 can generate and transmit a power and time delay profile (PTDP). A PTDP may be generated for each base station, or equivalently, for each reference signal transmitted by a base station, where the UE220 receives this reference signal as one or more propagating signals depending on the propagation path, as further illustrated in the following figure. The PTDP shows the power and time delay for each received propagating signal. Generally, the line-of-sight path yields a propagating signal with the strongest power and smallest delay compared to the reflected path. Therefore, when the PTDP of a reference signal shows a propagating signal that satisfies these criteria, this propagating signal can be selected and used in the UE220's location estimation (as in the case of reference signal transmission by base stations 210-1 and 210-2). However, when the PTDP of the reference signal does not indicate these references (for example, the propagating signal with the strongest power does not have the smallest delay), it can be assumed that none of the propagating signals follow line-of-sight transmission, and instead, each propagating signal follows a different reflection path (as in the case of reference signal transmission by base station 210-3). In this case, the strongest propagating signal may be selected, or different propagating signals may be filtered out. 【0032】 In addition to using PTDP reports, accuracy improvements can be further achieved by inputting PTDP reports and other types of information into the fusion algorithm, as further illustrated in the following figure. Other types of information relate to reference signal transmissions (e.g., transmit beam information for each reference signal), base stations 210 (e.g., their locations), reflectors 230 (e.g., maps of their locations, descriptions of their reflectivity, etc.), and / or UE220. As far as UE220 is concerned, the relevant information may be available from one or more sensors 240-1, 240-2, and 240-3, each of which may be coupled with a base station (e.g., installed at a base station, colocated with a base station, or in a location known to the base station). In one example, the sensor may be an optical sensor (e.g., a camera) that generates sensor data that forms an image on which the location of UE220 can be determined based on geometric reconstruction. In another example, the sensor may be a radar that determines the distance, angle, and / or velocity of UE220 on which the location of UE can be determined. In both examples, the relevant information is raw sensor data and / or estimated location. 【0033】 For example, referring again to the reference signal transmitted by base station 210-3, the PTDP of this reference signal can indicate that line-of-sight propagation may not exist. This indication can be confirmed by image data generated by sensor 240-3 (in this case, a camera) coupled with base station 210-3. The two corresponding propagation signals can be filtered out. Alternatively, the location of UE220 can be estimated from reference signals transmitted by base stations 210-1 and 210-2 (where each of these signals follows a corresponding line-of-sight path), and can be further refined based on image data generated by sensor 240-1 coupled with base station 210-1 and sensor 240-2 coupled with base station 210-2. 【0034】 Figure 3 shows an example of a PTDP according to one embodiment. In particular, propagation signal measurement 300 is performed with respect to a reference signal 310. For clarity of explanation, three reference signals 310-1, 310-2, and 310-3 are shown in Figure 3, corresponding to the reference signals transmitted by base stations 210-1, 210-2, and 210-3 in Figure 2, respectively. In particular, the UE (for example, UE220) receives three propagating signals corresponding to a first reference signal 310-1 (one of which follows a line-of-sight path and the other two follow reflected paths, each of which corresponds to a reference signal 310-1 received from a first base station 210-1), three propagating signals corresponding to a second reference signal 310-2 (one of which follows a line-of-sight path and the other two follow reflected paths, each of which corresponds to a reference signal 310-2 received from a second base station 210-2), and two propagating signals corresponding to a third reference signal 310-3 (both of which follow reflected paths, each of which corresponds to a reference signal 310-3 received from a third base station 210-3). 【0035】 In one example, the propagation signal measurement 300 includes the power and time delay of each propagation signal. Power is the power at which the UE receives the propagation signal. Time delay is the time difference between the transmission of the corresponding reference signal and the reception of the propagation signal. In the example in Figure 3, power could be absolute power 302 in dBm units (for example, the measured power of the received propagation signal, referenced to 1 milliwatt). Time delay could be absolute time delay 304 (corresponding to, for example, the channel propagation delay, the internal delay of the UE's modem, and the cumulative timing advance command for synchronizing the appropriate base station and UE clocks). 【0036】 In the example in Figure 3, the power and time delay of each propagating signal are indicated by upward arrows. More specifically, the measurements for three propagating signals corresponding to the first reference signal 310-1 are shown in the upper plot, where the leftmost arrow corresponds to line-of-sight propagation with the strongest power and smallest time delay. The two arrows on the right correspond to reflected propagation with lower power and larger time delay. Similarly, the measurements for three propagating signals corresponding to the second reference signal 310-2 are shown in the middle plot, where the leftmost arrow corresponds to line-of-sight propagation with the strongest power and smallest time delay. The two arrows on the right correspond to reflected propagation with lower power and larger time delay. In addition, the measurements for two propagating signals corresponding to the third reference signal 310-3 are shown in the lower plot, where the leftmost arrow shows a relatively smaller delay than the arrows on the right, while also having lower power. Thus, these two propagating signals can be assumed to follow a reflected path. 【0037】 Based on the propagation signal measurement 300, the UE can report the PTDP for each base station. Various types of information may be included in the PTDP, and various structures of the report are possible. 【0038】 In one example, PTDP is defined by the absolute time delay and absolute power (pair [t] for each propagation of the reference signal. i , p i ] j This is expressed as follows, where "j" is the identifier of the reference signal or the identifier of the base station that transmitted the reference signal (for example, "j" is the cell identifier), and where "i" is the identifier of the received propagating signal (for example, the index). For example, [t1, p1]2 is the absolute time delay and absolute power of the first propagating signal corresponding to the second reference signal 310-2. 【0039】 In this example too, a power threshold 330 can be used. The power threshold can be a pre-defined amount of power (e.g., an absolute amount of pre-defined power). When the power of the propagated signal exceeds the power threshold 330, the corresponding power and time (e.g., [t i , p i ) are included in the report. Otherwise, these measurement values are not included in the report. 【0040】 In addition, for each of the reference signals 310 (or the corresponding base station or cell), the UE has a set {[t i , p i}, j where "j" is set to a reference signal identifier or cell identifier, where "i" varies from "1" to "k", and where "k" is the total number of propagations for each reference signal "j" that exceeds the power threshold 330. For example, in the illustration of FIG. 3, the PTDP of the first reference signal 310-1 consists of {[t1, p1], [t2, p2], [t3, p3]}1. Each set can be included in the same report or sent in separate reports. 【0041】 In another example, instead of reporting absolute measurement values, relative measurement values are reported. In particular, for each base station, the strongest power of the received propagated signal is determined. The power of each propagated signal can be reported as the logarithm of the ratio of this power to the strongest power. Additionally, for baseline comparison with other reference signals of other base stations, the strongest power (e.g., represented as absolute power) can be reported. Additionally or alternatively, for each base station, the shortest time delay or the time delay of the strongest propagated signal is reported. The difference between this time delay and the time delay of each of the remaining propagated signals is also reported. <000017*5> ​​Figure 4 shows an example of a fusion algorithm 410 for estimating a UE location 420 (e.g., the location of the UE) according to one embodiment. In this example, the fusion algorithm 410 receives multiple inputs, including a UE PTDP report 412 and other types of information, to output the UE location 420. Generally, a fusion algorithm can be implemented as a computer-readable program that can be hosted and run on a network entity such as a base station, a location server, the UE itself, another UE, or any other component of a cellular network (e.g., a gateway computer, a backend server, etc.). Figure 4 shows other types of information, including transmitted beam information 414, camera output 416, and radar output 416. However, additional or alternative types of information are possible, relating to the transmitted reference signal, the base station transmitting the reference signal, the reflector, and / or the UE. 【0043】 A UE PTDP report 412 represents a report determined and / or sent by the UE (for example, as described above with respect to Figure 3) and includes PTDP information. PTDP information may be power and time delay (e.g., absolute or relative power and time delay measurements) for each received reference signal. A single report may be sent by the UE to a network entity and may include PTDP for different reference signals received from different base stations. Alternatively, a single report may be sent per base station. 【0044】 The transmit beam information 414 includes information about the transmit beam used in each reference signal transmission. The camera output 416 includes raw image data generated by one or more cameras and / or an estimate of the UE location 420 derived from the image data. Similarly, the radar output 418 includes the distance, angle, and / or velocity of the UE 220 detected by one or more radars and / or an estimate of the UE location 420 derived from such radar data. 【0045】 Various implementations of the fusion algorithm 410 are possible. Generally, the fusion algorithm 410 may determine weights according to the PTDP itself and / or other inputs 414-418 and apply them to the reported PTDP. 【0046】 In one example, the fusion algorithm 410 selects a propagation signal for each base station based on the UE PTDP report 412 and other inputs 414-418, and estimates the UE location 420 using the RTT measurement for the selected propagation signal without further consideration of the other inputs 414-418. Specifically, for each base station, the propagation signal with the strongest power and the smallest propagation delay is selected. If none of the propagation signals corresponding to the reference signal transmitted from the base station meet these two criteria, the fusion algorithm 410 can filter out this reference signal (e.g., by setting its weight to zero). Alternatively, the fusion algorithm 410 can select one of the propagation signals by considering the other inputs 414-418. For example, the estimation of the UE location 420 may be derived from any or all of the other inputs 414-418, and the propagation signal that best fits this estimation (e.g., by having the closest time delay to this estimation) is selected. Once one propagation signal (if any) is selected for each base station, the fusion algorithm 410 uses that selected propagation signal across multiple base stations in the multilateration estimation of the UE location 420. In this case, fusion determines the weight of each selected propagation signal based on the reported power of that propagation signal. Generally, higher power corresponds to higher weights. In multilateration estimation, the margin around the estimation (e.g., the range of the circle diameter) can be inversely proportional to the weights (e.g., higher weights result in a smaller margin, which in turn leads to a more accurate estimation). 【0047】 In another example, the fusion algorithm 410 selects a propagation signal for each base station based on the UE PTDP report 412 and independently of other inputs 414-418, and estimates the UE location 420 using the RTT measurements for the selected propagation signals and the other inputs 414-418 without further consideration of the other inputs 414-418. Specifically, for each base station, the propagation signal with the strongest power and the smallest propagation delay is selected. If none of the propagation signals corresponding to the reference signal transmitted by the base station meet these two criteria, the fusion algorithm 410 can filter out this reference signal (for example, by setting its weight to zero). Once one propagation signal (if any) is selected for each base station, the fusion algorithm 410 uses that selected propagation signal in the multilateration estimation. In this case, the fusion determines the weight of each selected propagation signal based on the reported power of this propagation signal. Generally, higher power corresponds to higher weights. In multilateration estimation, the margin around the estimation (e.g., the range of the circle diameter) can be inversely proportional to the weights (for example, the larger the weight, the smaller the margin, which in turn leads to a more accurate estimation). Furthermore, for each of the other inputs 414-418, the fusion algorithm 410 also estimates the location of the UE and fuses the multilateration estimation and the other estimations to generate the UE location 420. 【0048】 In another example, the fusion algorithm 410 uses both the UE PTDP report 412 and the other inputs 414-418 to perform propagation signal selection and location estimation. Specifically, for each base station, the propagation signal with the strongest power and the smallest propagation delay is selected. If none of the propagation signals corresponding to the reference signal transmitted by the base station meet these two criteria, the fusion algorithm 410 can filter out this reference signal (for example, by setting its weight to zero). Alternatively, the fusion algorithm 410 can select one of the propagation signals by considering the other inputs 414-418. For example, the estimation of the UE location 420 may be derived from any or all of the other inputs 414-418, and the propagation signal that best fits this estimation (for example, by having the closest time delay to this estimation) is selected. Once one propagation signal (if any) is selected for each base station, the fusion algorithm 410 uses that selected propagation signal in the multilateration estimation. In this case, the fusion determines the weight of each selected propagation signal based on the reported power of the propagation signal. Generally, the higher the power, the higher the weight. In multilateration estimation, the margin around the estimation (e.g., the range of the circle diameter) can be inversely proportional to the weight (e.g., the larger the weight, the smaller the margin, which in turn leads to a more accurate estimation). Furthermore, for each of the other inputs 414-418, the fusion algorithm 410 also estimates the location of the UE and fuses the multilateration estimation and the other estimations to generate the UE location 420. 【0049】 Figure 5 is a sequence diagram illustrating an example of estimating a UE location (for example, the location of UE510) according to one embodiment. In this example, UE510 is communicating with a network entity 520. The network entity 520 could be a base station, a location server, another UE, or another component of a cellular network. 【0050】 In the first step, the network entity 520 transmits signaling information 522 to the UE 510. Generally, the signaling information 522 configures the UE 510 to generate and report PTDPs, each PTDP corresponding to a reference signal transmitted by a base station and indicating the power and time delay for each received propagating signal. For example, the signaling information 522 may indicate one or more parameters for a report regarding a reference signal transmitted by a base station. The base station may be the same as the network entity 520 or may be different from the network entity 520. The report may be specific to one base station or common to multiple base stations (in which case one or more parameters may also relate to other base stations and / or reference signals transmitted by such base stations). 【0051】 Next, UE 510 receives the propagation signals, each of which corresponds to the propagation path along which the reference signal was transmitted from the base station. In light of the signaling information 522, UE 510 generates a PTDP for each base station and sends a PTDP report 512 to the network entity 520. The PTDP report 512 may be specific to one base station or may be common to multiple base stations and may contain PTDPs of multiple reference signals transmitted from multiple base stations. 【0052】 Network entity 520 can receive the PTDP report 512 and determine the UE location. This determination does not require, but may involve, other types of information. If other types of information are not used, network entity 520 can select one propagation signal per base station (for example, based on power and time delay measurements of various propagation signals), determine weights based on the reported power measurements, and perform a multilateration estimation of the UE location based on the weights. If other types of information are used, the PTDP report 512 and other types of information are input to the fusion algorithm 530 of network entity 520, similar to the fusion algorithm 410 in Figure 4. The output of the fusion algorithm is the UE location estimation. 【0053】 Figure 5 shows that UE location estimation is performed by a network entity 520 other than UE 510, but embodiments of the present disclosure are not limited to such an example. Alternatively, UE 510 may receive signaling information 522 from network entity 520 and generate a PTDP report 512. UE 510 may, but is not required to, send the PTDP report 512 to network entity 520. 【0054】 In one example, UE510 does not perform this transmission and instead determines its location based on the PTDP report 512. In this example, the fusion algorithm may, but does not have to be, hosted on UE510. If hosted, UE510 can receive other types of information from network entity 520 and input the PTDP report 512 and other types of information into the fusion algorithm 530 to estimate the UE location. 【0055】 In another example, the transmission of a PTDP report 512 occurs. In this example, UE 510 receives supporting information from network entity 520 and can then estimate the UE location. The supporting information may include, for example, the selection of propagating signals based on the execution of a fusion algorithm 530 by network entity 520. In another example, the supporting information may include the output of a deep learning model that uses the PTDP report 512 to generate an absolute location. The absolute location may be in local or global coordinates (e.g., latitude and longitude). 【0056】 In a further example, network entity 520 is another UE located in the same area as UE 510. A sidelink channel may exist between UE 510 and the other UE, and the PTDP report 512 may be sent via the sidelink channel. In this example, the other UE may already be performing positioning in that area. Therefore, the other UE may already be profiling that area (e.g., generating a PTDP) and / or receiving support information. Based on this existing data, the other UE can assist UE 510 in determining its UE location (e.g., by sending a PTDP from another device, sending support information, etc.). 【0057】 Figure 6 is a sequence diagram showing an example of sending signaling information 622 to UE 610 according to one embodiment. The network entity 620 sends this signaling information 622, where the network entity 620 may be a base station (e.g., a base station of a serving cell), a location server, another UE, or another component of the cellular network. The signaling information 622 is an example of the signaling information 522 in Figure 5. In particular, rather than each neighboring cell (e.g., a base station 630 that provides coverage of neighboring cells to a serving cell) sending its own signaling information specific to the reference signal transmitted in the neighboring cell (e.g., by base station 630), the network entity 620 sends a single set of signaling information 622 applicable to the serving cell and neighboring cells. 【0058】 In one example, signaling information 622 includes a list of cells and / or remote radio heads (RRHs) for measuring PTDP (including per-cell pseudo-collocation (QCL) indications). Signaling information 622 also includes the power threshold of the reported taps in the PTDP (e.g., power threshold 330 in Figure 3) and the maximum number of propagating signals per reference signal to be reported. 【0059】 Figure 7 is a sequence diagram showing another example of sending signaling information 722 and 732 to UE 710 according to one embodiment. Base station 720 (for example, a base station in a serving cell) sends first signaling information 722. Base station 730 (for example, a base station in a neighboring cell) sends second signaling information 732. Each of the signaling information 722 and 732 is an example of signaling information 522 in Figure 5. 【0060】 Here, unlike the example in Figure 6, each base station transmitting a reference signal to the UE 710 sends its own unique signaling information to configure the UE to generate and report a PTDP specific to the reference signal (or equivalently, specific to the base station). In one example, since each of the signaling information 722 and 732 is specific to a cell, the signaling information 722 and 732 do not need to contain a list of cells for measuring the PTDP, respectively. Instead, each of the signaling information 722 and 732 contains the power threshold of the reported tap in the PTDP (e.g., power threshold 330 in Figure 3) and the maximum number of propagating signals per base station to be reported, and the power threshold and maximum number may differ between the signaling information 722 and 732. 【0061】 Figure 8 is a sequence diagram showing an example of reporting PTDP according to one embodiment. UE810 communicates with base station 820 (e.g., the base station of the serving cell) and base station 830 (e.g., the base station of the neighboring cell) and receives signaling information to report PTDP for each reference signal transmitted by base stations 820 and 830, respectively. 【0062】 As shown, the first base station 820 transmits a first reference signal 822 to the UE 810. Due to multipath propagation, the UE 810 receives one or more first propagating signals (not shown in Figure 8) corresponding to the first reference signal 822. For each received propagating signal corresponding to the first reference signal 822, the UE 810 performs power and time measurements (absolute and / or relative) on the received propagating signal and includes the power and time measurements as a pair in the PTDP of the first reference signal 822. Similarly, the second base station 830 transmits a second reference signal 832. The UE 810 receives one or more second propagating signals corresponding to the second reference signal 832, performs power and time measurements, and includes the power and time measurements in the PTDP of the second reference signal 832. 【0063】 Subsequently, UE810 sends a PTDP report 812 to the first base station 820 (for example, the base station of the serving cell, the base station that sent signaling information for all reference signals to UE810, or the base station that performs location estimation). The PTDP report 812 includes the PTDPs for the first reference signal 822 and the second reference signal 832, respectively. 【0064】 If base station 820 includes a network entity that estimates the location of UE 810, base station 820 relies on PTDP report 812 to do so. Otherwise, base station 820 sends PTDP report 812 to the appropriate network entity. 【0065】 Figure 9 is a sequence diagram showing another example of reporting PTDP according to one embodiment. UE910 is communicating with base station 920 (e.g., the base station of the serving cell) and base station 930 (e.g., the base station of the neighboring cell) and receiving signaling information to report PTDP for each reference signal transmitted by base stations 920 and 930. Here, instead of sending a single PTDP report containing PTDP for all reference signals, UE910 sends a PTDP report for each reference signal. 【0066】 As shown, the first base station 920 transmits a first reference signal 922 to the UE 910. Due to multipath propagation, the UE 910 receives one or more first propagating signals corresponding to the first reference signal 922. For each received propagating signal, the UE 910 performs power and time measurements (absolute and / or relative) on the received propagating signal and includes the power and time measurements as a pair in the PTDP of the first reference signal 922. The UE 910 sends a PTDP report 912 containing the PTDP of the first reference signal 922 to the first base station 920. 【0067】 Similarly, the second base station 930 transmits a second reference signal 932. The UE 910 receives one or more second propagating signals corresponding to the second reference signal 932, performs power and time measurements, includes the power and time measurements in the PTDP of the second reference signal 932, and sends a PTDP report 914 containing the PTDP of the second reference signal 932 to the second base station 930. 【0068】 If the first base station 920 is the network entity that estimates the location of the UE 910, the second base station 930 sends a PTDP report 914 to the first base station 920. The first base station 920 also relies on both PTDP reports 912 and 914 to estimate the location of the UE 910. Otherwise, both base stations 920 and 930 send their PTDP reports 912 and 914 to the appropriate network entity. 【0069】 Figure 10 is a sequence diagram illustrating yet another example of reporting PTDP according to one embodiment. UE1010 communicates with base station 1020 (e.g., the base station of the serving cell) and base station 1030 (e.g., the base station of the neighboring cell) and receives signaling information to report PTDP for each reference signal transmitted by base stations 1020 and 1030. Here, instead of sending a single PTDP report containing PTDPs for all reference signals, UE1010 sends a PTDP report for each reference signal, and the PTDP report is sent to only one base station (such as base station 1020, where this base station 1020 could be the base station of the serving cell, the base station that sent the signaling information for all reference signals to UE1010, or the base station that performs location estimation). 【0070】 As shown, the first base station 1020 transmits a first reference signal 1022 to the UE 1010. Due to multipath propagation, the UE 1010 receives one or more first propagating signals corresponding to the first reference signal 1022. For each received propagating signal, the UE 1010 performs power and time measurements (absolute and / or relative measurements) on the received propagating signal and includes the power and time measurements as a pair in the PTDP of the first reference signal 1022. The UE 1010 sends a PTDP report 1012 containing the PTDP of the first reference signal 1022 to the first base station 1020. 【0071】 Similarly, the second base station 1030 transmits a second reference signal 1032. The UE 1010 receives one or more second propagating signals corresponding to the second reference signal 1032, performs power and time measurements, includes the power and time measurements in the PTDP of the second reference signal 1032, and sends a PTDP report 1014 containing the PTDP of the second reference signal 1032 to the first base station 1020. 【0072】 If the first base station 1020 is the network entity that estimates the location of UE1010, the first base station 1020 relies on both PTDP reports 1012 and 1014 to estimate the location of UE1010. Otherwise, base station 1020 sends PTDP reports 1012 and 1014 to the appropriate network entity. 【0073】 Figure 11 is a sequence diagram showing an example of sending beam information and sensor output according to one embodiment. As described above in this specification, beam information and sensor output (e.g., raw image data, raw radar data, and / or location estimates derived from raw image data and / or radar data) may be input to a fusion algorithm in addition to one or more PTDP reports. The fusion algorithm then outputs location estimates. 【0074】 In the example in Figure 11, UE1110 communicates with base stations 1120 and 1130, receiving signaling information to report PTDPs for each reference signal transmitted by each of the base stations 1120 and 1130, and sending one or more PTDP reports accordingly. In addition, base station 1130 sends its beam information and sensor output 1132 (for example, the transmitted beam of the reference signal of base station 1130 transmitted to UE1110, and second sensor data and / or location estimates from the sensor database coupled with base station 1130) to UE1110. The UE then sends the beam information and sensor output 1134 to base station 1120 (where base station 1120 could be the serving cell base station, the base station that sent the signaling information for all reference signals to UE1110, or the base station that performs location estimation). If base station 1120 is a network entity that executes a fusion algorithm, base station 1120 determines the location of UE 1110 based on beam information and sensor output 1134. Otherwise, base station 1120 sends beam information and sensor output 1134, as well as its own beam information and sensor output, to the appropriate network entity. 【0075】 Figure 12 is a sequence diagram showing another example of sending beam information and sensor outputs according to one embodiment. Here, UE1210 communicates with base stations 1220 and 1230, receives signaling information to report PTDPs for each reference signal transmitted by each of base stations 1220 and 1230, and sends one or more PTDP reports accordingly. In addition, base station 1230 sends its beam information and sensor outputs 1232 (for example, the transmitted beam of base station 1230's reference signal transmitted to UE1210 and second sensor data and / or location estimates from a sensor database coupled with base station 1230) to base station 1220 (where base station 1220 could be the serving cell base station, the base station that sent signaling information for all reference signals to UE1210, or the base station that performs location estimation). If base station 1220 is a network entity that performs a fusion algorithm, base station 1220 determines the location of UE1210 based on the beam information and sensor outputs 1232. Otherwise, the base station 1220 sends beam information and sensor output 1232, as well as its own beam information and sensor output, to the appropriate network entity. 【0076】 Figure 13 is a flowchart illustrating an example of a method for reporting power and time delay profiles according to one embodiment. The method may represent a method implemented by a device for reporting positioning-related information to a network entity. The network entity may be a base station, a location server, another UE, or another component of a cellular network. Thus, the functions shown in the blocks of Figure 13 may be performed by a device. Furthermore, the means for performing the functions may include hardware and / or software components of device 1500 shown in Figure 15, which may include a UE. In addition, it should be noted that, as with other figures attached to this specification, Figure 13 is provided as a non-limiting example. Other embodiments may vary depending on the desired function. For example, the functional blocks shown in the method may be combined, separated, or rearranged to adapt to different embodiments. 【0077】 In block 1302, the function is to receive signaling information indicating one or more parameters for reporting on a reference signal, wherein one or more parameters identify one or more base stations. In one example, the signaling information is received from a network entity, which sends signaling information for all base stations (e.g., within the RF range of the device) communicating with the device, as illustrated in Figure 6. In this example, one or more parameters identify one or more base stations in which power and time delay measurements should be included in the report. One or more parameters further identify a power threshold associated with reporting power and time delay measurements per base station, and the first power and first time delay of a first reference signal received from a base station are included in the report when it is determined that the first power exceeds the power threshold. In addition, one or more parameters further identify the maximum number of propagating signals to be measured per base station, and the report includes a total number of power measurements per base station equal to or less than the maximum number. In one example, one or more parameters include a list of cells and / or RRHs for measuring PTDP (including per-cell QCL indications), a power threshold for reported taps in PTDP (e.g., power threshold 330 in Figure 3), and the maximum number of propagating signals to be reported received from the base station. In another example, as in the example in Figure 7, the network entity is a base station, which sends signaling information specific to the base station. The device also receives appropriate signaling information from each of the other base stations (e.g., second signaling information from a second base station). Here, the per-base station signaling information may include, for example, the power threshold for reported taps in PTDP (e.g., power threshold 330 in Figure 3) and the maximum number of propagating signals to be reported received from the corresponding base station. 【0078】 Means for performing the functions in block 1302 may include software and / or hardware components of the device, such as the bus 1505, the processing unit 1510, the DSP 1520, the wireless communication interface 1530, the memory 1560, and / or other components of the device 1500 shown in Figure 15 and described in more detail below. 【0079】 In block 1304, the function includes determining, based on signaling information, power and time delay profiles for one or more reference signals received from one or more base stations, wherein the power and time delay profile for each of the one or more reference signals includes power and time delay information for each of the one or more propagating signals corresponding to each of the reference signals. In one example, a base station transmits a reference signal to a device. Due to possible multipath propagation, the device receives one or more propagating signals from the base station, each of which corresponds to the reception of a reference signal along its propagation path. Depending on the physical environment, one propagating signal may be a reference signal received along a line-of-sight path. Another propagating signal may be a reflection of a reference signal received along a reflection path. Similarly, a second base station (and other base stations as well) may transmit a second reference signal. The power and time delay profiles identify the absolute power and absolute time delay for each reference signal received from the base station. In particular, the function in block 1304 is to determine a first propagation signal among a first plurality of propagation signals received from a first base station, that the first propagation signal has the strongest absolute power among the first plurality of propagation signals, to determine the absolute time delay of the first propagation signal (for example, as the sum of propagation delay, the device's modem's internal delay, and cumulative timing advance commands), and to include the strongest absolute power and absolute time delay in the report. In addition, depending on the physical environment, the report indicates that, for a first propagation signal corresponding to a line-of-sight transmission of a reference signal from the base station and a second propagation signal corresponding to a reflection of the first reference signal, (i) the first absolute power of the first propagation signal is greater than the second absolute power of the second propagation signal, and (ii) the first absolute time delay of the first propagation signal is less than the second absolute time delay of the second propagation signal.Alternatively or additionally, the report may indicate, for a first and second propagating signal corresponding to a reference signal, (i) the power difference between the first and second propagating signals and (ii) the relative time delay between the first and second propagating signals, wherein the first propagating signal has a stronger absolute power than the second propagating signal, and the report may further indicate the stronger absolute power and absolute time delay of the first propagating signal. 【0080】 As described above in this specification, in Figures 8 to 10, the device can send a single report containing power delay profiles of different reference signals received from multiple base stations, or it can send reports for each power delay profile (e.g., a report per base station). In the former case, the function in block 1304 is to include in the report a second power and time delay profile corresponding to a second set of propagation signals received from a second base station (e.g., corresponding to a second reference signal transmitted by a second base station), based on signaling information. In the latter case, the function in block 1304 is to generate a second report based on signaling information (if one signaling information is received for all base stations) or second signaling information (if one signaling information is received per base station), wherein the second report includes a second power and time delay for a second set of propagation signals received from a second base station. 【0081】 Means for performing the functions in block 1304 may include software and / or hardware components of the device, such as the bus 1505, the processing unit 1510, the DSP 1520, the wireless communication interface 1530, the memory 1560, and / or other components of the device 1500 shown in Figure 15 and described in more detail below. 【0082】 In block 1306, the function is to send a report to a network entity, the report including a power and time delay profile. The location of the device is determined by the network entity based on the report. Additionally or alternatively, the UE may determine its location based on the report and optionally on supporting information, which may be received from the network entity based on the report. If a second report is generated (to a second reference signal, or equivalently, a report specific to a second base station), the function in block 1306 is to transmit the second report to the network entity, the location of the device is further determined based on the second report. 【0083】 Means for performing the functions in block 1306 may include software and / or hardware components of the device, such as the bus 1505, the processing unit 1510, the DSP 1520, the wireless communication interface 1530, the memory 1560, and / or other components of the device 1500 shown in Figure 15 and described in more detail below. 【0084】 With respect to Figure 11, as described above in this specification, the device can receive beam information and sensor outputs from a base station and transmit them to a network entity. Thus, the function of the method may further include receiving beam information from a base station associated with the transmission of a reference signal by the base station, and transmitting the beam information to a network entity, the location of the device further determined by the network entity (or device) based on the beam information. The function may also include receiving sensor information from a sensor associated with a base station associated with the detection of user equipment by the sensor, and transmitting the sensor information to a network entity, the location of the device further determined by the network entity (or device) based on the sensor information. 【0085】 In this case, the location of the device is further determined by the network entity (or device) based on a fusion algorithm that has inputs including reports, beam information, and sensor information. In one example, the fusion algorithm selects a reference signal received from a base station for each base station based on the corresponding power and corresponding time delay of the reference signal from the reports. In another example, the fusion algorithm selects a reference signal received from a base station for each base station based on at least one of beam information or sensor information. In yet another example, the fusion algorithm selects a reference signal received from a base station for each base station, determines a weight for the selected reference signal based on the corresponding power of the selected propagation signal from the reports, and the location of the device is further determined by the network entity (or device) based on the weight of the selected propagation signal. 【0086】 Figure 14 is a flowchart illustrating an example of a method for determining the location of a device according to one embodiment. The method may represent a method implemented by a network entity for positioning a device. The network entity may be a base station, a location server, another UE, or another component of a cellular network. Thus, the functions shown in the blocks of Figure 14 may be performed by a network entity. Furthermore, the means for performing the functions may include hardware and / or software components of the network entity 1600 shown in Figure 16. In addition, it should be noted that, as with other figures attached to this specification, Figure 14 is provided as a non-limiting example. Other embodiments may vary depending on the desired function. For example, the functional blocks shown in the method may be combined, separated, or rearranged to adapt to different embodiments. 【0087】 In block 1402, the function includes sending signaling information to a device, wherein the signaling information indicates one or more parameters for reporting on a reference signal. In one example, as illustrated in Figure 6, a network entity sends signaling information for all base stations communicating with the device (e.g., within the RF range of the device). In this example, one or more parameters identify one or more base stations for which power and time delay measurements should be included in the report. One or more parameters further identify a power threshold associated with reporting power and time delay measurements per base station, and the first power and first time delay of a first propagating signal are included in the report when it is determined that the first power exceeds the power threshold. In addition, one or more parameters further identify the maximum number of propagating signals to be measured per base station, and the report includes a total number of power measurements per base station equal to or less than the maximum number. In one example, one or more parameters include a list of cells and / or RRHs for measuring PTDP (including per-cell QCL indications), a power threshold for reported taps in PTDP (e.g., power threshold 330 in Figure 3), and the maximum number of propagating signals per base station to be reported. In another example, as in the example in Figure 7, the network entity is a base station, which sends signaling information specific to the base station. The device also receives appropriate signaling information from each of the other base stations (e.g., second signaling information from a second base station), where the per-base station signaling information may include, for example, the power threshold for reported taps in PTDP (e.g., power threshold 330 in Figure 3) and the maximum number of propagating signals to be reported. 【0088】 Means for performing the functions in block 1402 may include software and / or hardware components of the network entity, such as the bus 1605, the processing unit 1610, the DSP 1620, the wireless communication interface 1630, the memory 1660, and / or other components of the network entity 1600 shown in Figure 16 and described in more detail below. 【0089】 In block 1404, the function is to receive a report from a device based on signaling information, wherein the report includes power and time delay profiles for one or more reference signals received by the device from one or more base stations, and the power and time delay profile for each of the one or more reference signals includes power and time delay information for each of the one or more propagating signals corresponding to each of the respective reference signals. In one example, the report includes power and time delay profiles for the reference signals. For example, the power and time delay profiles identify the absolute power and absolute time delay for each reference signal received by the device from the base station. In addition, depending on the physical environment, the report indicates that for a first propagating signal corresponding to a line-of-sight transmission from a base station and a second propagating signal corresponding to a reflection of the first reference signal, (i) the first absolute power of the first propagating signal is greater than the second absolute power of the second propagating signal, and (ii) the first absolute time delay of the first propagating signal is less than the second absolute time delay of the second propagating signal. Alternatively or additionally, the report may indicate, for the first and second propagating signals received from the base station, (i) the power difference between the first and second propagating signals and (ii) the relative time delay between the first and second propagating signals, with the first propagating signal having the strongest absolute power, and the report may further indicate the strongest absolute power and absolute time delay of the first propagating signal. 【0090】 As described above in this specification, in Figures 8 to 10, the device may send a single report containing power and time delay profiles of different reference signals transmitted by different base stations, or it may send reports for each power and time delay profile. In the former case, the function in block 1404 is for a network entity to receive a report common to all base stations, the report further including a second power and time delay profile corresponding to a second plurality of propagation signals corresponding to the second reference signal received by the device from the second base station at the time of the second transmission of the second reference signal by the second base station. In the latter case, the function in block 1404 is for a network entity to receive a second report from the device, the second report including a second power and time delay profile corresponding to a second plurality of propagation signals received from the second base station at the time of the second reference signal transmission by the second base station, and the location of the device is further determined based on the second report. 【0091】 Means for performing the functions in block 1404 may include software and / or hardware components of the network entity, such as the bus 1605, the processing unit 1610, the DSP 1620, the wireless communication interface 1630, the memory 1660, and / or other components of the network entity 1600 shown in Figure 16 and described in more detail below. 【0092】 In block 1406, the function includes determining the location of a device based on reports. In one example, the network entity uses only reports (or only various received reports) to derive the location of a device based on multilateration estimation. In another example, the network entity uses additional types of information, such as beam information and sensor outputs, to derive the location based on a fusion algorithm. 【0093】 In the latter example, the function of the method is to receive beam information from a base station or device associated with the transmission of a reference signal by the base station, the location of the device is further determined based on the beam information. The function is to receive sensor information from a base station or device associated with the detection of user equipment by a sensor associated with the base station, the location of the device is further determined by a network entity based on the sensor information. 【0094】 The location of the device is further determined based on a fusion algorithm that has inputs including reports, beam information, and sensor information. In one example, the fusion algorithm selects a reference signal for each base station based on the corresponding power and corresponding time delay of the propagation from the reports. In another example, the fusion algorithm selects a reference signal for each base station based on at least one of the beam information or sensor information. In yet another example, the fusion algorithm selects a reference signal for each base station, determines weights for the selected reference signals based on the corresponding power of the selected reference signals from the reports, and the location of the device is further determined by the network entities based on the weights of the selected reference signals. 【0095】 Means for performing the functions in block 1406 may include software and / or hardware components of the network entity, such as the bus 1605, the processing unit 1610, the DSP 1620, the wireless communication interface 1630, the memory 1660, and / or other components of the network entity 1600 shown in Figure 16 and described in more detail below. 【0096】 Figure 15 is a block diagram of one embodiment of device 1500, which may be used as described herein and in embodiments described in relation to Figures 1 to 14.
