[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This Patent Application claims priority to Greek Patent Application No. 20200100222, filed May 4, 2020, entitled “SIDELINK-ASSISTED POSITIONING,” assigned to the assignee hereof. The disclosure of the priority application is considered part of the disclosure of this Patent Application and is hereby incorporated by reference into this Patent Application. TECHNICAL FIELD
[0003] Aspects of the present disclosure relate generally to wireless communication, and more specifically to techniques and apparatuses for sidelink-assisted positioning. BACKGROUND
[0004] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems can employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, or the like). Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3 GPP).
[0005] A wireless network can include a number of base stations (BSs) that can support communication for a number of user equipment (UEs). A UE can communicate with a BS via the downlink and uplink. The downlink (or forward link) refers to the communication from the BS to the UE, and the uplink (or reverse link) refers to the communication from the UE to the BS. As will be described in more detail, a BS can be referred to as a Node B, a gNB, an access point (AP), a radio head, a transmit receive point (TRP), a new radio (NR) BS, a 5G Node B, or the like.
[0006] The above multiple access technologies have been adopted in various telecommunication standards to provide common protocol that enables different wireless devices to communicate on a municipal, national, regional, and even global level. NR, which can also be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by improving spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink (DL), using CP- OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM)) on the uplink (UL), as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. Further improvements to LTE and other radio access technologies can also be considered. SUMMARY

[0011] In some aspects, a non-transitory computer-readable medium can store one or more instructions for wireless communication. The one or more instructions, when executed by one or more processors of a UE, can cause the one or more processors to transmit, to another UE, a positioning request associated with a procedure for determining a location of the UE, wherein the positioning request includes sidelink communications between a first S-LMC of the UE and a second S-LMC of the other UE, wherein the first S-LMC and the second S-LMC include sub-functions associated with a V2X protocol layer; and receive a positioning report associated with the procedure for determining the location of the UE, wherein the positioning report includes an indication of the location of the UE based at least in part on a determination by an S-LMF.

[0025] Various aspects of the disclosure are more fully described below with reference to the figures. The disclosure may, however, be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Based on the teachings herein one skilled in the art should appreciate that the scope of the disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently of or combined with any other aspect of the disclosure. For example, an apparatus can be implemented or a method can be practiced using any number of the aspects set forth herein. In addition, the scope of the disclosure is intended to cover such an apparatus or method which is practiced using, combined with other
[0026] Several aspects of telecommunication systems will now be presented with reference to various apparatus and methods. These apparatus and methods will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, and / or the like (collectively referred to as “elements”). These elements can be implemented using hardware, software, or combinations thereof. Whether such elements are implemented as hardware or software depends on the particular application and design constraints imposed on the overall system.
[0027] It should be noted that while aspects can be described herein using terminology commonly associated with a 5G or NR radio access technology (RAT), aspects of the present disclosure can be applied to other RATs, such as a 3G RAT, a 4G RAT, and / or a RAT subsequent to 5G (e.g., 6G).
[0028] Figure 1 FIG. 1 is a diagram illustrating an example of a wireless network 100 in accordance with the present disclosure. In other examples, the wireless network 100 can be or include elements of a 5G (NR) network and / or an LTE network. The wireless network 100 can include a number of base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 1 lOd) and other network entities. A base station (BS) is an entity that communicates with user equipment (UEs) and can also be referred to as an NR BS, a Node B, a gNB, a 5G node B (NB), an access point, a transmit receive point (TRP), and / or the like. Each BS can provide communication coverage for a particular geographic area. In 3GPP, the term “cell” can refer to a coverage area of a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.
[0029] A BS can provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell can cover a relatively large geographic area (e.g., several kilometers in radius) and can allow unrestricted access by UEs with service subscriptions appropriate for the Figure 1 In the example shown, BS 110a can be a macro BS for a macro cell 102a, BS 110b can be a pico BS for a pico cell 102b, and BS 110c can be a femto BS for a femto cell 102c. A BS can support one or multiple (e.g., three) cells. The terms“eNB,”“base station,”“NR BS,”“gNB,”“TRP,”“AP,”“node B,”“5G NB,” and“cell” can be used interchangeably herein.
[0030] In some aspects, a cell can not necessarily be stationary, and the geographic area of the cell can move according to the location of a mobile BS. In some aspects, a BS can interconnect with other BSs or network nodes (not shown) in the wireless network 100 using any suitable transfer network, such as a direct physical connection, or a virtual network.
[0031] Wireless network 100 can also include relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a BS or a UE) and send a transmission of the data to a downstream station (e.g., a UE or a BS). A relay station can also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown, a relay BS 1 lOd can communicate with macro BS 110a and a UE 120d in order to facilitate communication between BS 110a and UE 120d. A relay BS can also be referred to as a relay station, a relay base station, a repeater, or the like.
[0032] Wireless network 100 can be a heterogeneous network that includes BSs of different types, such as macro BSs, pico BSs, femto BSs, relay BSs, or the like. These different types of BSs can have different transmit power levels, different coverage areas, and different impacts on interference. For example, macro BSs can have a high transmit power level (e.g., 5 to 40 Watts) whereas pico BSs, femto BSs, and relay BSs can have lower transmit power levels (e.g., 0.1 to 2 Watts).
[0033] A network controller 130 can couple to a set of BSs and can provide coordination and control for these BSs. Network controller 130 can be in communication with the BSs via a backhaul. The BSs can also communicate with one another directly or indirectly via a wireless or wireline backhaul.
[0034] UEs 120 (e.g., 120a, 120b, 120c) can be dispersed throughout wireless network 100, and each UE can be stationary or mobile. A UE can also be referred to as an access terminal, a terminal, a mobile station, a subscriber unit, a station, etc. A UE can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biometric sensor / device, a wearable device such as a smart watch, smart clothing, smart glasses, a smart wrist band, smart jewelry (e.g., a smart ring, a smart bracelet), an entertainment device (e.g., a music or video device or a satellite radio), a vehicular component or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, or any other suitable device that is configured to communicate via a wireless or wired medium.
[0035] Some UEs can be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags, that can communicate with a base station, another device (e.g., remote device), or some other entity. A wireless node can provide, for example, connectivity for or to a network (e.g., a wide area network such as Internet or a cellular network) via a wired or wireless communication link. Some UEs can be considered Intemet-of-Things (IoT) devices, and / or can be implemented as NB-IoT (narrowband
[0036] In general, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a particular RAT and can operate on one or more frequencies. A RAT can also be referred to as a radio technology, an air interface, or the like. A frequency can also be referred to as a carrier, a frequency channel, or the like. Each frequency can support a single RAT in a given geographic area in order to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks can be deployed.
[0037] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary to communicate with one another). For example, UE 120 can perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by the base station 110. Some UEs 120 can be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags, that can communicate with a base station, another device (e.g., remote device), or some other entity. A wireless node can provide, for example, connectivity for or to a network (e.g., a wide area network such as Internet or a cellular network) via a wired or wireless communication link. Some UEs can be considered Intemet-of-Things (IoT) devices, and / or can be implemented as NB-IoT (narrowband
[0038] Devices of wireless network 100 may communicate using the electromagnetic spectrum, which may be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, devices of wireless network 100 may communicate using an operating band having a first frequency range (FR1) spanning from 410 MHz to 7.125 GHz, and / or an operating band having a second frequency range (FR2) spanning from 24.25 GHz to 52.6 GHz. Frequencies between FR1 and FR2 are sometimes referred to as intermediate frequency (IF) bands. Although a portion of FR1 is greater than 6 GHz, FR1 is generally referred to as the “less than 6 GHz” band. Similarly, although different from the extremely high frequency (EHF) band (30 GHz–300 GHz) recognized as a “millimeter wave” band by the International Telecommunication Union (ITU), FR2 is generally referred to as the “millimeter wave” band. Therefore, unless explicitly stated otherwise, it should be understood that the terms “less than 6 GHz”, etc. (if used herein), can broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or intermediate frequency (e.g., greater than 7.125 GHz). Similarly, unless otherwise explicitly stated, it should be understood that the terms “millimeter wave” and the like (if used herein) can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or intermediate frequency band frequencies (e.g., less than 24.25 GHz). It is anticipated that the frequencies included in FR1 and FR2 may be modified, and the techniques described herein are applicable to those modified frequency ranges.
[0039] As pointed out above, Figure 1 This is provided as an example. Other examples may be provided related to... Figure 1 The descriptions are different.
[0040] Figure 2 This is a diagram illustrating an example 200 of a base station 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with T antennas 234a to 234t, and the UE 120 may be equipped with R antennas 252a to 252r, wherein generally T ≥ 1 and R ≥ 1.
[0041] At base station 110, a transmit processor 220 can receive data from a data source 212 for one or more UEs, select one or more modulation and coding schemes (MCS) for each UE based at least in part on channel quality indicators (CQIs) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS(s) selected for the UE, and provide data symbols for all UEs. Transmit processor 220 can also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling) and provide overhead symbols and control symbols. Transmit processor 220 can also generate reference symbols for reference signals (e.g., a cell-specific reference signal (CRS) or a demodulation reference signal (DMRS)) and synchronization signals (e.g., a primary synchronization signal (PSS) and a secondary synchronization signal (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding) on the data symbols, the control symbols, the overhead symbols, and / or the reference symbols, if applicable, and can provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 can process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 can further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. T downlink signals from modulators 232a through 232t can be transmitted via T antennas 234a through 234t, respectively.
[0042] At the UE 120, the antennas 252a-252r can receive the downlink signals from the base station 110 and / or other base stations and can provide received signals to the demodulators (DEMODs) 254a-254r, respectively. Each demodulator 254 can condition (e.g., filter, amplify, downconvert, and digitize) a received signal to obtain input samples. Each demodulator 254 can further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 can obtain received symbols from all R demodulators 254a-254r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. A receive processor 258 can process (e.g., demodulate and decode) the detected symbols, provide decoded data for the UE 120 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The term “controller / processor” can refer to one or more controllers, one or more processors, or combinations thereof. In other examples, a channel processor can determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal receiving quality (RSRQ) parameter, and / or a CQI parameter. In some aspects, one or more components of UE 120 can be included in a housing 284.
[0043] The network controller 130 can include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 can include, for example, one or more devices in a core network. The network controller 130 can communicate with the base station 110 via the communication unit 294.
[0044] In other examples, the antennas (e.g., antennas 234a-234t and / or antennas 252a-252r) can include or be included within one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays. The antenna panels, antenna groups, antenna element sets, and / or antenna arrays can include one or more antenna elements. The antenna panels, antenna groups, antenna element sets, and / or antenna arrays can include a set of co-planar antenna elements and / or a set of non-co-planar antenna elements. The antenna panels, antenna groups, antenna element sets, and / or antenna arrays can include antenna elements within a single housing and / or antenna elements within multiple housings. The antenna panels, antenna groups, antenna element sets, and / or antenna arrays can include one or more antenna elements that are coupled to one or more transmit and / or receive components, such as Figure 2 one or more components of the UE 120.
[0045] On the uplink, at UE 120, a transmit processor 264 can receive and process data from a data source 262 and control information (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI) from controller / processor 280. Transmit processor 264 can also generate reference symbols for one or more reference signals. The symbols from transmit processor 264 can be precoded by a TX MIMO processor 266 if applicable, further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to base station 110. In some aspects, a modulator and a demodulator (e.g., MOD / DEMOD 254) of the UE 120 can be included in a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver can include any combination of antennas 252, modulators and / or demodulators 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver can be used by a processor (e.g., controller / processor 280) and memory 282 to perform any of the aspects of the methods described herein, for example, as described with reference to Figures 5 to 9 the descriptions.
[0046] At base station 110, the uplink signals from UE 120 and other UEs can be received by antennas 234, processed by demodulators 232, detected by a MIMO detector 236 if applicable, and further processed by a receive processor 238 to obtain decoded data and control information sent by UE 120. Receive processor 238 can provide the decoded data to a data sink 239 and the decoded control information to controller / processor 240. Base station 110 can include communication unit 244 and communicate to network controller 130 via communication unit 244. Base station 110 can include scheduler 246 to schedule UEs 120 for downlink and / or uplink communications. In some aspects, a modulator and a demodulator (e.g., MOD / DEMOD 232) of the base station 110 can be included in a modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver can include any combination of antennas 234, modulators and / or demodulators 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver can be used by a processor (e.g., controller / processor 240) and memory 242 to perform any of the aspects of the methods described herein, for example, as described with reference to Figures 5 to 9 the descriptions.
[0047] The controller / processor 240 of base station 110, the controller / processor 280 of UE 120 and / or Figure 2 Any other components may perform one or more techniques associated with sidelink-assisted positioning, as described in more detail elsewhere herein. For example, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component can perform or direct (e.g.) Figure 8 The process 800 Figure 9 The operation of process 900 and / or other processes as described herein. Memory 242 and 282 may store data and program code for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, one or more instructions may cause one or more processors, UE 120 and / or base station 100 to execute or direct (e.g., directly, or after compilation, translation and / or interpretation) when executed by one or more processors of base station 110 and / or UE 120.

[0048] In some aspects, UE 120 may include components for sending a location request associated with a procedure for determining the location of a UE to another UE, wherein the location request includes sidelink communication between a first (S-LMC) of the UE and a second S-LMC of the other UE, wherein the first S-LMC and the second S-LMC include sub-functions associated with the V2X protocol layer; and components for receiving a location report associated with a procedure for determining the location of a UE, wherein the location report includes an indication of the UE's location determined at least in part by a sidelink location management function (S-LMF), etc. In some aspects, these components may include combinations of Figure 2 One or more components of the described UE 120, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, etc.
[0049] In some aspects, UE 120 can include means for receiving, from another UE, a positioning request associated with a procedure for determining a position of the other UE, wherein the positioning request includes a sidelink communication between a first S-LMC of the UE and a second S-LMC of the other UE, wherein the first S-LMC and the second S-LMC include sub-functions associated with V2X protocol layers; means for receiving, from the S-LMF, a positioning report associated with the procedure for determining the position of the UE, wherein the positioning report includes an indication of the position of the UE based at least in part on a determination by the S-LMF; and means for transmitting the positioning report to the other UE, and / or the like. In some aspects, such means can include one or more components of UE 120 described in connection with Figure 2 One or more components of UE 120 described are described, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, and / or the like.

For example, the functions described above with respect to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 can be performed by controller / processor 280 or under the control of controller / processor 280.
[0051] As indicated above, Figure 2 are provided as examples. Other examples can differ from what is described in connection with respect to Figure 2 the described.
[0052] Figure 3 is a diagram illustrating an example 300 of sidelink communication, in accordance with the present disclosure.
[0053] As Figure 3As shown, the first UE 305-1 can communicate with the second UE 305-2 (and one or more other UEs 305) via one or more sidelink channels 310. The UEs 305-1 and 305-2 can communicate using one or more sidelink channels 310 for P2P communication, D2D communication, V2X communication (which can include V2V communication, V2I communication, and / or vehicle-to-pedestrian (V2P) communication, for example) and / or mesh networking. In some aspects, the UEs 305 (e.g., UE 305-1 and / or UE 305-2) can correspond to one or more other UEs described elsewhere herein, such as the UEs 120. In some aspects, the one or more sidelink channels 310 can use a PC5 interface and / or can operate at a high frequency band (e.g., a 5.9 GHz band). Additionally, or alternatively, the UEs 305 can synchronize timing of transmission time intervals (TTIs) (e.g., frames, subframes, slots, or symbols) using global navigation satellite system (GNSS) timing.
[0054] As Figure 3 Further as shown, the one or more sidelink channels 310 can include a physical sidelink control channel (PSCCH) 315, a physical sidelink shared channel (PSSCH) 320, and / or a physical sidelink feedback channel (PSFCH) 325. The PSCCH 315 can be used to convey control information, similar to a physical downlink control channel (PDCCH) and / or a physical uplink control channel (PUCCH) used for cellular communications with a base station 110 via an access link or access channel. The PSSCH 320 can be used to convey data, similar to a physical downlink shared channel (PDSCH) and / or a physical uplink shared channel (PUSCH) used for cellular communications with a base station 110 via an access link or access channel. For example, the PSCCH 315 can carry sidelink control information (SCI) 330, which can indicate various control information for sidelink communications, such as one or more resources (e.g., time resources, frequency resources, and / or spatial resources) in which a transport block (TB) 335 can be carried on the PSSCH 320. The TB 335 can include data. The PSFCH 325 can be used to convey sidelink feedback 340, such as hybrid automatic repeat request (HARQ) feedback (e.g., acknowledgement or negative-acknowledgement (ACK / NACK) information), transmission power control (TPC), and / or a scheduling request (SR).
[0055] In some aspects, one or more of the sidelink channels 310 can use a resource pool. For example, a scheduling assignment (e.g., included in SCI 330) can be transmitted in a subchannel in time using particular resource blocks (RBs). In some aspects, a data transmission associated with the scheduling assignment (e.g., on PSSCH 320) can occupy adjacent RBs in the same subframe as the scheduling assignment (e.g., using frequency division multiplexing). In some aspects, the scheduling assignment and associated data transmission are not transmitted on adjacent RBs.
[0056] In some aspects, the UE 305 can operate using a transmission mode in which resource selection and / or scheduling is performed by the UE 305 (e.g., rather than a base station 110). In some aspects, the UE 305 can perform resource selection and / or scheduling by sensing channel availability for transmission. For example, the UE 305 can measure an RSSI parameter (e.g., a Sidelink-RSSI (S-RSSI) parameter) associated with various sidelink channels, can measure an RSRP parameter (e.g., a PSSCH-RSRP parameter) associated with various sidelink channels, and / or can measure an RSRQ parameter (e.g., a PSSCH-RSRQ parameter) associated with various sidelink channels, and can select a channel for a sidelink communication transmission based at least in part on the measurements.
[0057] Additionally or alternatively, the UE 305 can perform resource selection and / or scheduling using SCI 330 received in PSCCH 315, which can indicate occupied resources and / or channel parameters. Additionally or alternatively, the UE 305 can perform resource selection and / or scheduling by determining a channel busy rate (CBR) associated with various sidelink channels, which can be used for rate control (e.g., by indicating a maximum number of resource blocks that the UE 305 can use for a particular set of subframes).
[0058] In a transmission mode in which resource selection and / or scheduling is performed by the UE 305, the UE 305 can generate a sidelink grant and can transmit the grant in SCI 330. The sidelink grant can indicate, for example, one or more parameters (e.g., transmission parameters) to be used for an upcoming sidelink transmission, such as one or more resource blocks to be used for the upcoming sidelink transmission (e.g., for a TB 335), one or more subframes to be used for the upcoming sidelink transmission, and / or an MCS to be used for the upcoming sidelink transmission. In some aspects, the UE 305 can generate a sidelink grant that indicates one or more parameters for semi-persistent scheduling (SPS), such as a periodicity of sidelink transmissions. Additionally, or alternatively, the UE 305 can generate a sidelink grant for event-driven scheduling, such as for on-demand sidelink messages.
[0059] As indicated above, Figure 3 are provided as examples. Other examples can differ from what is described Figure 3 in relation to what is described.
[0060] Figure 4 is a diagram illustrating an example 400 of sidelink communications and access link communications, in accordance with the present disclosure.
[0061] As Figure 4 illustrated, a transmitter (Tx) / receiver (Rx) UE 405 and an Rx / Tx UE 410 can communicate with one another via a sidelink, as described above in connection with Figure 3 FIG. 2. As further illustrated, in some sidelink modes, a base station 110 can communicate with the Tx / Rx UE 405 via a first access link. Additionally, or alternatively, in some sidelink modes, the base station 110 can communicate with the Rx / Tx UE 410 via a second access link. The Tx / Rx UE 405 and / or the Rx / Tx UE 410 can correspond to one or more UEs described elsewhere herein, such as the UEs 120 of Figure 1 FIG. 1. Thus, a direct link between UEs 120 (e.g., via a PC5 interface) can be referred to as a sidelink, and a direct link between a base station 110 and a UE 120 (e.g., via a Uu interface) can be referred to as an access link. Sidelink communications can be transmitted via the sidelink, and access link communications can be transmitted via the access link. An access link communication can be a downlink communication (from the base station 110 to the UE 120) or an uplink communication (from the UE 120 to the base station 110).
[0062] As indicated above, Figure 4 are provided as examples. Other examples can differ from what is described Figure 4 in relation to what is described.
[0063] V2X positioning can involve a UE associated with a vehicle or pedestrian using other UEs associated with roadside units (RSUs), other vehicles, other pedestrians, and / or the like to position itself. V2X positioning can include, for example, infrastructure-to-vehicle (I2V) positioning, V2V positioning, V2P positioning, and / or the like.
[0064] V2X positioning methods can differ from UE positioning methods based on an access link (Uu). In Uu-based positioning, a location management function (LMF) maintained in a NR core network determines a location of a UE based on input from the UE and / or measurements obtained by a RAN (e.g., base stations, and / or the like). Uu-based positioning can benefit from performing calculations in the core network, which can provide a large amount of computing power. However, a UE can not always have access to the core network. Moreover, to support Uu-based positioning, signaling overhead can be introduced between the UE, one or more base stations, the core network, and / or the like. Uu-based positioning can also have accuracy limitations due to only using measurements from the UE being positioned and / or base stations with which the UE is in communication.
[0065] V2X positioning can leverage accurate information of vehicle maneuverability and vehicle speed. For example, although a particular location of a UE can be unknown to the UE, a relative displacement over successive time instances can be known accurately using motion sensors associated with the vehicle. Vehicle motion can enable large changes in angular position with respect to an anchoring device, which is a device that is not in motion, such as, for example, an RSU, and / or the like. Thus, multiple time measurements can be used to improve location accuracy.
[0066] In sidelink-based positioning, a UE associated with a vehicle can determine a location of the UE using positioning reference signal (PRS)-based measurements made by the UE associated with the vehicle and / or an anchoring UE. In this way, the UE can benefit from vehicle knowledge of the vehicle’s own speed, speed error, global positioning system (GPS) measurements, GPS error, and / or the like. The UE can use this information, transmit-receive calibration error, and / or the like to determine a location of the UE based at least in part on multiple measurements over time. The UE can determine its location without relying on another entity, such as an RSU, a central server, and / or the like. However, accuracy of the location determination can be limited by a single perspective from which measurements are obtained and / or calculated.
[0067] Various aspects of the techniques and apparatuses described herein can facilitate sidelink-assisted positioning using an LMF and multiple UEs. In some aspects, the LMF can be hosted by a network operator and can be maintained in an NR core network. In some aspects, the LMF can be hosted by a road operator and can be maintained in a V2X application server. In some aspects, sidelink-assisted positioning can benefit from measurements based on multiple perspectives. In some aspects, since each of the UEs will have a different perspective of the movement of the UE relative to it, the determination of the location of the UE can be more accurate when based at least in part on positioning measurements obtained by different UEs. In some aspects, the position of the UE is determined using sidelink-based measurements. In some aspects, an S-LMC is provided as a sub-function in a V2X layer of the UE. The S-LMC can support one or more functions that enable sidelink-assisted positioning. In some aspects, the S-LMC can support most or all of the functions that are typically provided by an LMF operated by a network.
[0068] In some aspects, a UE associated with a vehicle can obtain positioning measurements using round trip time (RTT) measurements based on communications with another UE. The other UE can be associated with another vehicle, an RSU, and / or the like. In some aspects, the UEs can transmit PRS to each other and obtain positioning measurements associated with the UEs based on the PRS. The other UE can provide the positioning measurements to the LMF (directly or through another UE), and the LMF can determine its location based at least in part on the positioning measurements received from the UEs, other UEs, and / or the like. In this way, the LMF can use input from other devices representing other perspectives to determine the location of the UE. Since the UEs do not have to perform the calculations, performing the calculations by the LMF can save UE power and time.
[0069] Figure 5 FIG. 5 is a diagram illustrating an example 500 of an architecture for sidelink-assisted positioning, in accordance with the present disclosure. As shown, a first UE 120 (shown as “UE A”), a second UE 120 (shown as “UE B”), and a third UE 120 (shown as “UE C”) can communicate with each other via sidelink communications 505.

[0071] In some aspects, any one or more of the UE A 120, the UE B 120, and the UE C 120 can be associated with a pedestrian, a vehicle, an RSU, or the like.

Figure 5 Further shown, UE A 120 can include a first S-LMC 545, UE B 120 can include a second S-LMC 550, and UE C 120 can include a third S-LMC 555. The S-LMCs 545, 550, and 555 can be provided in a V2X protocol layer in a protocol stack associated with each UE 120. In some aspects, one or more of the S-LMCs 545, 550, and 555 can support one or more operations similar to operations that can be supported by the LMF 510. In some aspects, communications between UEs 120 described herein can refer to communications between respective S-LMCs of the UEs 120. Similarly, in some aspects, communications between a UE 120 and the S-LMF 510 described herein can refer to communications between the UE 120 and respective S-LMCs of the S-LMF 510. In some aspects, one or more of the S-LMCs 545, 550, and 555 can support all operations typically supported by an LMF. In some aspects, for example, one or more of the S-LMCs 545, 550, and 555 can support a capability request operation, a capability response operation, an assistance data reception operation, an assistance data provision operation, a measurement operation, a measurement reception operation, a first position determination operation associated with a UE, a second position determination operation associated with another UE, and / or the like.

[0074] In some aspects, the S-LMF 510 can determine a position of UE A 120. UE B 120 and / or UE C 120 can determine a position of UE A 120 based at least in part on positioning measurements obtained by UE A 120, UE B 120, UE C 120, and / or the like. In some aspects, the positioning measurements can include RTT measurements made by one or more of the UEs 120 based on PRS transmissions via the sidelink communications 505.
[0075] The S-LMF 510 can receive positioning measurements from the UE A 120, the UE B 120, the UE C 120, and / or the like. In some aspects, the S-LMF 510 can obtain positioning measurements associated with the UE A 120 based on PRS transmissions, vehicle sensors (e.g., wheel sensors, and / or the like), and / or the like.

The S-LMF 510 can determine a location of the UE A 120 based at least in part on one or more of the positioning measurements.
[0076] Various aspects of the techniques and apparatuses described herein can facilitate sidelink-assisted positioning using an S-LMF and multiple UEs. In some aspects, a UE associated with a vehicle can obtain positioning measurements using RTT measurements based on communications with another UE. In some aspects, the S-LMF can use input from other devices representing other perspectives to determine a location of the UE. Performing the calculations by the S-LMF can conserve UE power, processing resources, and / or the like.
