DETAILED DESCRIPTION

Various aspects of the disclosure are described more fully hereinafter with reference to the accompanying drawings. This 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. 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 may be implemented or a method may 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 other structure, functionality, or structure and functionality in addition to or other than the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of a claim.

Several aspects of telecommunication systems will now be presented with reference to various apparatuses and techniques. These apparatuses and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, or the like (collectively referred to as “elements”). These elements may be implemented using hardware, software, or combinations thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.

While aspects may be described herein using terminology commonly associated with a 5G or New Radio (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).

FIG.1is a diagram illustrating an example of a wireless network100, in accordance with the present disclosure. The wireless network100may be or may include elements of a 5G (e.g., NR) network and/or a 4G (e.g., Long Term Evolution (LTE)) network, among other examples. The wireless network100may include one or more base stations110(shown as a BS110a, a BS110b, a BS110c, and a BS110d), a user equipment (UE)120or multiple UEs120(shown as a UE120a, a UE120b, a UE120c, a UE120d, and a UE120e), and/or other network entities. A base station110is an entity that communicates with UEs120. A base station110(sometimes referred to as a BS) may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, and/or a transmission reception point (TRP). Each base station110may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term “cell” can refer to a coverage area of a base station110and/or a base station subsystem serving this coverage area, depending on the context in which the term is used.

A base station110may provide communication coverage for a macro cell, a pico cell, a femto cell, and/or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs120with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs120with service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs120having association with the femto cell (e.g., UEs120in a closed subscriber group (CSG)). A base station110for a macro cell may be referred to as a macro base station. A base station110for a pico cell may be referred to as a pico base station. A base station110for a femto cell may be referred to as a femto base station or an in-home base station. In the example shown inFIG.1, the BS110amay be a macro base station for a macro cell102a, the BS110bmay be a pico base station for a pico cell102b, and the BS110cmay be a femto base station for a femto cell102c. A base station may support one or multiple (e.g., three) cells.

In some examples, a cell may not necessarily be stationary, and the geographic area of the cell may move according to the location of a base station110that is mobile (e.g., a mobile base station). In some examples, the base stations110may be interconnected to one another and/or to one or more other base stations110or network nodes (not shown) in the wireless network100through various types of backhaul interfaces, such as a direct physical connection or a virtual network, using any suitable transport network.

The wireless network100may include one or more relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a base station110or a UE120) and send a transmission of the data to a downstream station (e.g., a UE120or a base station110). A relay station may be a UE120that can relay transmissions for other UEs120. In the example shown inFIG.1, the BS110d(e.g., a relay base station) may communicate with the BS110a(e.g., a macro base station) and the UE120din order to facilitate communication between the BS110aand the UE120d. A base station110that relays communications may be referred to as a relay station, a relay base station, a relay, or the like.

The wireless network100may be a heterogeneous network that includes base stations110of different types, such as macro base stations, pico base stations, femto base stations, relay base stations, or the like. These different types of base stations110may have different transmit power levels, different coverage areas, and/or different impacts on interference in the wireless network100. For example, macro base stations may have a high transmit power level (e.g., 5 to 40 watts) whereas pico base stations, femto base stations, and relay base stations may have lower transmit power levels (e.g., 0.1 to 2 watts).

A network controller130may couple to or communicate with a set of base stations110and may provide coordination and control for these base stations110. The network controller130may communicate with the base stations110via a backhaul communication link. The base stations110may communicate with one another directly or indirectly via a wireless or wireline backhaul communication link.

The UEs120may be dispersed throughout the wireless network100, and each UE120may be stationary or mobile. A UE120may include, for example, an access terminal, a terminal, a mobile station, and/or a subscriber unit. A UE120may 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, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device, and/or a satellite radio), a vehicular component or sensor, a smart meter/sensor, industrial manufacturing equipment, a global positioning system device, and/or any other suitable device that is configured to communicate via a wireless medium.

Some UEs120may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. An MTC UE and/or an eMTC UE may include, for example, a robot, a drone, a remote device, a sensor, a meter, a monitor, and/or a location tag, that may communicate with a base station, another device (e.g., a remote device), or some other entity. Some UEs120may be considered Internet-of-Things (IoT) devices, and/or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs120may be considered a Customer Premises Equipment. A UE120may be included inside a housing that houses components of the UE120, such as processor components and/or memory components. In some examples, the processor components and the memory components may be coupled together. For example, the processor components (e.g., one or more processors) and the memory components (e.g., a memory) may be operatively coupled, communicatively coupled, electronically coupled, and/or electrically coupled.

In general, any number of wireless networks100may be deployed in a given geographic area. Each wireless network100may support a particular RAT and may operate on one or more frequencies. A RAT may be referred to as a radio technology, an air interface, or the like. A frequency may be referred to as a carrier, a frequency channel, or the like. Each frequency may 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 may be deployed.

In some examples, two or more UEs120(e.g., shown as UE120aand UE120e) may communicate directly using one or more sidelink channels (e.g., without using a base station110as an intermediary to communicate with one another). For example, the UEs120may communicate using peer-to-peer (P2P) communications, device-to-device (D2D) communications, a vehicle-to-everything (V2X) protocol (e.g., which may include a vehicle-to-vehicle (V2V) protocol, a vehicle-to-infrastructure (V2I) protocol, or a vehicle-to-pedestrian (V2P) protocol), and/or a mesh network. In such examples, a UE120may perform scheduling operations, resource selection operations, and/or other operations described elsewhere herein as being performed by the base station110.

Devices of the wireless network100may communicate using the electromagnetic spectrum, which may be subdivided by frequency or wavelength into various classes, bands, channels, or the like. For example, devices of the wireless network100may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHZ). It should be understood that although a portion of FR1 is greater than 6 GHZ, FR1 is often referred to (interchangeably) as a “Sub-6 GHz” band in various documents and articles. A similar nomenclature issue sometimes occurs with regard to FR2, which is often referred to (interchangeably) as a “millimeter wave” band in documents and articles, despite being different from the extremely high frequency (EHF) band (30 GHz-300 GHz) which is identified by the International Telecommunications Union (ITU) as a “millimeter wave” band.

The frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Recent 5G NR studies have identified an operating band for these mid-band frequencies as frequency range designation FR3 (7.125 GHz-24.25 GHZ). Frequency bands falling within FR3 may inherit FR1 characteristics and/or FR2 characteristics, and thus may effectively extend features of FR1 and/or FR2 into mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6 GHz-71 GHz), FR4 (52.6 GHz-114.25 GHZ), and FR5 (114.25 GHZ-300 GHz). Each of these higher frequency bands falls within the EHF band.

With the above examples in mind, unless specifically stated otherwise, it should be understood that the term “sub-6 GHz” or the like, if used herein, may broadly represent frequencies that may be less than 6 GHz, may be within FR1, or may include mid-band frequencies. Further, unless specifically stated otherwise, it should be understood that the term “millimeter wave” or the like, if used herein, may broadly represent frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1, and/or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and/or FR5) may be modified, and techniques described herein are applicable to those modified frequency ranges.

In some aspects, a mobile station, such as the UE120, may include a communication manager140. As described in more detail elsewhere herein, the communication manager140may receive first information identifying a value for a threshold parameter associated with a sidelink positioning procedure; and transmit second information identifying a suitability for anchoring the sidelink positioning procedure, wherein the suitability is associated with the value for the threshold parameter. Additionally, or alternatively, the communication manager140may perform one or more other operations described herein.

In some aspects, the base station110may include a communication manager150. As described in more detail elsewhere herein, the communication manager150may transmit, to a mobile station, first information identifying a value for a threshold parameter associated with a sidelink positioning procedure; and receive, from the mobile station, second information identifying a suitability for anchoring the sidelink positioning procedure, wherein the suitability is associated with the value for the threshold parameter. Additionally, or alternatively, the communication manager150may perform one or more other operations described herein.

As indicated above,FIG.1is provided as an example. Other examples may differ from what is described with regard toFIG.1.

FIG.2is a diagram illustrating an example200of a base station110in communication with a UE120in a wireless network100, in accordance with the present disclosure. The base station110may be equipped with a set of antennas234athrough234t, such as T antennas (T≥1). The UE120may be equipped with a set of antennas252athrough252r, such as R antennas (R≥1).

At the base station110, a transmit processor220may receive data, from a data source212, intended for the UE120(or a set of UEs120). The transmit processor220may select one or more modulation and coding schemes (MCSs) for the UE120based at least in part on one or more channel quality indicators (CQIs) received from that UE120. The UE120may process (e.g., encode and modulate) the data for the UE120based at least in part on the MCS(s) selected for the UE120and may provide data symbols for the UE120. The transmit processor220may 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. The transmit processor220may 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) or a secondary synchronization signal (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor230may perform spatial processing (e.g., precoding) on the data symbols, the control symbols, the overhead symbols, and/or the reference symbols, if applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems232(e.g., T modems), shown as modems232athrough232t. For example, each output symbol stream may be provided to a modulator component (shown as MOD) of a modem232. Each modem232may use a respective modulator component to process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem232may further use a respective modulator component to process (e.g., convert to analog, amplify, filter, and/or upconvert) the output sample stream to obtain a downlink signal. The modems232athrough232tmay transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas234(e.g., T antennas), shown as antennas234athrough234t.

At the UE120, a set of antennas252(shown as antennas252athrough252r) may receive the downlink signals from the base station110and/or other base stations110and may provide a set of received signals (e.g., R received signals) to a set of modems254(e.g., R modems), shown as modems254athrough254r. For example, each received signal may be provided to a demodulator component (shown as DEMOD) of a modem254. Each modem254may use a respective demodulator component to condition (e.g., filter, amplify, downconvert, and/or digitize) a received signal to obtain input samples. Each modem254may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector256may obtain received symbols from the modems254, may perform MIMO detection on the received symbols if applicable, and may provide detected symbols. A receive processor258may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE120to a data sink260, and may provide decoded control information and system information to a controller/processor280. The term “controller/processor” may refer to one or more controllers, one or more processors, or a combination thereof. A channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and/or a CQI parameter, among other examples. In some examples, one or more components of the UE120may be included in a housing284.

The network controller130may include a communication unit294, a controller/processor290, and a memory292. The network controller130may include, for example, one or more devices in a core network. The network controller130may communicate with the base station110via the communication unit294.

One or more antennas (e.g., antennas234athrough234tand/or antennas252athrough252r) may include, or may be included within, one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and/or one or more antenna arrays, among other examples. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include one or more antenna elements (within a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements, and/or one or more antenna elements coupled to one or more transmission and/or reception components, such as one or more components ofFIG.2.

On the uplink, at the UE120, a transmit processor264may receive and process data from a data source262and control information (e.g., for reports that include RSRP, RSSI, RSRQ, and/or CQI) from the controller/processor280. The transmit processor264may generate reference symbols for one or more reference signals. The symbols from the transmit processor264may be precoded by a TX MIMO processor266if applicable, further processed by the modems254(e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station110. In some examples, the modem254of the UE120may include a modulator and a demodulator. In some examples, the UE120includes a transceiver. The transceiver may include any combination of the antenna(s)252, the modem(s)254, the MIMO detector256, the receive processor258, the transmit processor264, and/or the TX MIMO processor266. The transceiver may be used by a processor (e.g., the controller/processor280) and the memory282to perform aspects of any of the methods described herein (e.g., with reference toFIGS.6-10).

At the base station110, the uplink signals from UE120and/or other UEs may be received by the antennas234, processed by the modem232(e.g., a demodulator component, shown as DEMOD, of the modem232), detected by a MIMO detector236if applicable, and further processed by a receive processor238to obtain decoded data and control information sent by the UE120. The receive processor238may provide the decoded data to a data sink239and provide the decoded control information to the controller/processor240. The base station110may include a communication unit244and may communicate with the network controller130via the communication unit244. The base station110may include a scheduler246to schedule one or more UEs120for downlink and/or uplink communications. In some examples, the modem232of the base station110may include a modulator and a demodulator. In some examples, the base station110includes a transceiver. The transceiver may include any combination of the antenna(s)234, the modem(s)232, the MIMO detector236, the receive processor238, the transmit processor220, and/or the TX MIMO processor230. The transceiver may be used by a processor (e.g., the controller/processor240) and the memory242to perform aspects of any of the methods described herein (e.g., with reference toFIGS.6-10).

The controller/processor240of the base station110, the controller/processor280of the UE120, and/or any other component(s) ofFIG.2may perform one or more techniques associated with sidelink positioning anchor configuration, as described in more detail elsewhere herein. For example, the controller/processor240of the base station110, the controller/processor280of the UE120, and/or any other component(s) ofFIG.2may perform or direct operations of, for example, process700ofFIG.7, process800ofFIG.8, and/or other processes as described herein. The memory242and the memory282may store data and program codes for the base station110and the UE120, respectively. In some examples, the memory242and/or the memory282may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and/or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compiling, converting, and/or interpreting) by one or more processors of the base station110and/or the UE120, may cause the one or more processors, the UE120, and/or the base station110to perform or direct operations of, for example, process700ofFIG.7, process800ofFIG.8, and/or other processes as described herein. In some examples, executing instructions may include running the instructions, converting the instructions, compiling the instructions, and/or interpreting the instructions, among other examples.

In some aspects, a mobile station, such as the UE120, includes means for receiving first information identifying a value for a threshold parameter associated with a sidelink positioning procedure; and/or means for transmitting second information identifying a suitability for anchoring the sidelink positioning procedure, wherein the suitability is associated with the value for the threshold parameter. In some aspects, the means for the mobile station to perform operations described herein may include, for example, one or more of communication manager140, antenna252, modem254, MIMO detector256, receive processor258, transmit processor264, TX MIMO processor266, controller/processor280, or memory282.

In some aspects, the base station includes means for transmitting, to a mobile station, first information identifying a value for a threshold parameter associated with a sidelink positioning procedure; and/or means for receiving, from the mobile station, second information identifying a suitability for anchoring the sidelink positioning procedure, wherein the suitability is associated with the value for the threshold parameter. The means for the base station to perform operations described herein may include, for example, one or more of communication manager150, transmit processor220, TX MIMO processor230, modem232, antenna234, MIMO detector236, receive processor238, controller/processor240, memory242, or scheduler246.

While blocks inFIG.2are illustrated as distinct components, the functions described above with respect to the blocks may be implemented in a single hardware, software, or combination component or in various combinations of components. For example, the functions described with respect to the transmit processor264, the receive processor258, and/or the TX MIMO processor266may be performed by or under the control of the controller/processor280.

As indicated above,FIG.2is provided as an example. Other examples may differ from what is described with regard toFIG.2.

FIG.3is a diagram illustrating an example300of sidelink communications, in accordance with the present disclosure.

As shown inFIG.3, a first UE305-1may communicate with a second UE305-2(and one or more other UEs305) via one or more sidelink channels310. For example, a first UE305-1may communicate with the second UE305-2to perform ranging and determine a relative distance between UEs305(e.g., UE305-1and/or UE305-2) or an absolute position for first UE305-1or second UE305-2. The UEs305-1and305-2may communicate using the one or more sidelink channels310for P2P communications, D2D communications, V2X communications (e.g., which may include V2V communications, V2I communications, and/or V2P communications) and/or mesh networking. In some aspects, the UEs305may correspond to one or more other UEs or mobile stations described elsewhere herein, such as UE120. In some aspects, the one or more sidelink channels310may use a PC5 interface and/or may operate in a high frequency band (e.g., the 5.9 GHz band). Additionally, or alternatively, the UEs305may synchronize timing of transmission time intervals (TTIs) (e.g., frames, subframes, slots, or symbols) using global navigation satellite system (GNSS) timing.

As further shown inFIG.3, the one or more sidelink channels310may 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 PSCCH315may be used to communicate 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 station110via an access link or an access channel. The PSSCH320may be used to communicate data, similar to a physical downlink shared channel (PDSCH) and/or a physical uplink shared channel (PUSCH) used for cellular communications with a base station110via an access link or an access channel. For example, the PSCCH315may carry sidelink control information (SCI)330, which may indicate various control information used for sidelink communications, such as one or more resources (e.g., time resources, frequency resources, and/or spatial resources) where a transport block (TB)335may be carried on the PSSCH320. The TB335may include data. The PSFCH325may be used to communicate sidelink feedback340, such as hybrid automatic repeat request (HARQ) feedback (e.g., acknowledgement or negative acknowledgement (ACK/NACK) information), transmit power control (TPC), and/or a scheduling request (SR).

Although shown on the PSCCH315, in some aspects, the SCI330may include multiple communications in different stages, such as a first stage SCI (SCI-1) and a second stage SCI (SCI-2). The SCI-1 may be transmitted on the PSCCH315. The SCI-2 may be transmitted on the PSSCH320. The SCI-1 may include, for example, an indication of one or more resources (e.g., time resources, frequency resources, and/or spatial resources) on the PSSCH320, information for decoding sidelink communications on the PSSCH, a quality of service (QOS) priority value, a resource reservation period, a PSSCH demodulation reference signal (DMRS) pattern, an SCI format for the SCI-2, a beta offset for the SCI-2, a quantity of PSSCH DMRS ports, and/or a modulation and coding scheme (MCS). The SCI-2 may include information associated with data transmissions on the PSSCH320, such as a hybrid automatic repeat request (HARQ) process ID, a new data indicator (NDI), a source identifier, a destination identifier, and/or a channel state information (CSI) report trigger.

In some aspects, the one or more sidelink channels310may use resource pools. For example, a scheduling assignment (e.g., included in SCI330) may be transmitted in sub-channels using specific resource blocks (RBs) across time. In some aspects, data transmissions (e.g., on the PSSCH320) associated with a scheduling assignment may occupy adjacent RBs in the same subframe as the scheduling assignment (e.g., using frequency division multiplexing). In some aspects, a scheduling assignment and associated data transmissions are not transmitted on adjacent RBs.

In some aspects, a UE305may operate using a transmission mode where resource selection and/or scheduling is performed by the UE305(e.g., rather than a base station110). In some aspects, the UE305may perform resource selection and/or scheduling by sensing channel availability for transmissions. For example, the UE305may measure a received signal strength indicator (RSSI) parameter (e.g., a sidelink-RSSI (S-RSSI) parameter) associated with various sidelink channels, may measure a reference signal received power (RSRP) parameter (e.g., a PSSCH-RSRP parameter) associated with various sidelink channels, and/or may measure a reference signal received quality (RSRQ) parameter (e.g., a PSSCH-RSRQ parameter) associated with various sidelink channels, and may select a channel for transmission of a sidelink communication based at least in part on the measurement(s).

Additionally, or alternatively, the UE305may perform resource selection and/or scheduling using SCI330received in the PSCCH315, which may indicate occupied resources and/or channel parameters. Additionally, or alternatively, the UE305may perform resource selection and/or scheduling by determining a channel busy rate (CBR) associated with various sidelink channels, which may be used for rate control (e.g., by indicating a maximum number of resource blocks that the UE305can use for a particular set of subframes).

In the transmission mode where resource selection and/or scheduling is performed by a UE305, the UE305may generate sidelink grants, and may transmit the grants in SCI330. A sidelink grant may 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 on the PSSCH320(e.g., for TBs335), one or more subframes to be used for the upcoming sidelink transmission, and/or a modulation and coding scheme (MCS) to be used for the upcoming sidelink transmission. In some aspects, a UE305may generate a sidelink grant that indicates one or more parameters for semi-persistent scheduling (SPS), such as a periodicity of a sidelink transmission. Additionally, or alternatively, the UE305may generate a sidelink grant for event-driven scheduling, such as for an on-demand sidelink message.

As indicated above,FIG.3is provided as an example. Other examples may differ from what is described with respect toFIG.3.

FIG.4is a diagram illustrating an example400of sidelink communications and access link communications, in accordance with the present disclosure.

As shown inFIG.4, a transmitter (Tx)/receiver (Rx) UE405and an Rx/Tx UE410may communicate with one another via a sidelink, as described above in connection withFIG.3. As further shown, in some sidelink modes, a base station110may communicate with the Tx/Rx UE405via a first access link. For example, as described in more detail herein, a base station110may provide configuration information identifying a threshold value for a parameter, such as an anchoring threshold value, to Tx/Rx UE405. Additionally, or alternatively, in some sidelink modes, the base station110may communicate with the Rx/Tx UE410via a second access link. The Tx/Rx UE405and/or the Rx/Tx UE410may correspond to one or more UEs described elsewhere herein, such as the UE120ofFIG.1. Thus, a direct link between UEs120(e.g., via a PC5 interface) may be referred to as a sidelink, and a direct link between a base station110and a UE120(e.g., via a Uu interface) may be referred to as an access link. Sidelink communications may be transmitted via the sidelink, and access link communications may be transmitted via the access link. An access link communication may be either a downlink communication (from a base station110to a UE120) or an uplink communication (from a UE120to a base station110).

As indicated above,FIG.4is provided as an example. Other examples may differ from what is described with respect toFIG.4.

FIGS.5A-5Dare diagrams illustrating examples500/520/540/560of sidelink positioning, in accordance with the present disclosure.

As further shown inFIG.5A, and by example500, a first UE502may have a known position and serve as an anchor for a sidelink positioning procedure (e.g., a ranging procedure) and a second UE504may have an unknown position. At506, first UE502and second UE504may communicate to exchange capability information. For example, first UE502may indicate that first UE502has a known position, thereby enabling second UE504to determine a position of second UE504based at least in part on the known position of first UE502. At508and510, first UE502may transmit a positioning reference signal (PRS) request and second UE504may transmit a PRS response. Based at least in part on the PRS request and PRS response, at512, first UE502and second UE504may transmit (e.g., on unlicensed spectrum) respective PRSs (e.g., wideband PRSs). At514and516, after transmitting the respective PRSs, first UE502and second UE504may exchange information indicating results of the respective PRSs, thereby enabling second UE504to determine a position based at least in part on the known position of first UE502. For example, first UE502and/or second UE504may transmit information enabling a determination of a round-trip-time (RTT) associated with the respective PRSs, thereby enabling a ranging determination (e.g., a determination of a distance between first UE502and second UE504). In this way, first UE502enables second UE504to determine an absolute position.

As shown inFIG.5B, and by example520, the first UE502may have an unknown position and second UE504may have an unknown position. In this case, neither first UE502nor second UE504can serve as an anchor for a sidelink positioning procedure. At526, first UE502and second UE504may communicate to exchange capability information. For example, first UE502and second UE504may each indicate an unknown position. In this case, first UE502and second UE504may determine that a result of performing a sidelink positioning procedure will be an inter-UE range (e.g., a distance between first UE502and second UE504) rather than an absolute position (e.g., a position of second UE504derived based at least in part on the known position of first UE502and a range between UEs502and504). At528and530, first UE502may transmit a PRS request and second UE504may transmit a PRS response. At532, first UE502and second UE504may transmit respective PRSs. At534and536, after transmitting the respective PRSs, first UE502and second UE504may exchange information indicating results of the respective PRSs, thereby enabling second UE504to determine a range between first UE502and second UE504(e.g., using RTT measurements performed based at least part on transmitting the respective PRSs and receiving the respective PRS results). In this way, first UE502and second UE504determine a relative position (e.g., an inter-UE range).

As shown inFIG.5C, and by example540, the first UE502may have a known position, the second UE504may have an unknown position, and a third UE542may have an unknown position. A base station544may, at546, provide information identifying an anchor accuracy threshold to the UEs502/504/542. For example, base station544may transmit information on a Uu interface to configure an anchor accuracy threshold. At548, UEs502/504/542may communicate with base station544to indicate a capability for serving as an anchor. For example, based on the anchor accuracy threshold and the known position, UE502may indicate suitability for serving as an anchor for a sidelink positioning procedure. In contrast, UEs504/542may indicate unsuitability for serving as an anchor. At550, base station110may transmit PRS requests to the UEs502/504/542. At552/554/556, UEs502/504/542may communicate to perform ranging using PRS transmissions. For example, UE502may transmit a PRS response (e.g., on a PC5 interface to UEs504/542) indicating that UE502will transmit a PRS, may transmit the PRS, and may receive results of transmitting the PRS from UEs504/542enabling a determination of a range. Similarly, UEs504/542may transmit PRSs and receive results (e.g., RTT determinations) of transmitting the PRSs. In this case, UEs504/542may determine an absolute position based at least in part on the known position of first UE502, which is serving as anchor for the positioning procedure. As shown inFIG.5D, in contrast, rather than PRS responses and PRS results being communicated between UEs502/504/542, the PRS responses and PRS results may be communicated to the base station544, which may disseminate results of the sidelink positioning procedure.

As indicated above,FIGS.5A-5Dare provided as examples. Other examples may differ from what is described with respect toFIGS.5A-5D.

As described herein, in non-network-managed sidelink positioning, as described with regard toFIGS.5A and5B, a first UE may determine whether the first UE has a known position and use the known position to perform a sidelink positioning procedure with a second UE. However, this may prevent a base station from constraining sidelink positioning procedures in any way. For example, when a large quantity of UEs are communicating in a network, an amount of network traffic associated with sidelink positioning procedures may exceed a threshold amount of traffic, causing latency or dropped communications for other UEs.

In contrast, network-managed sidelink positioning, as described with regard toFIGS.5C and5D, a base station may provide a threshold for the first UE to use in determining whether the known position is sufficiently accurate and the first UE may transmit capability information to the base station to indicate that the first UE is capable of serving as an anchor for a sidelink positioning procedure. In this case, the network may initiate the sidelink positioning procedure for the first UE and one or more second UEs based at least in part on the first UE indicating a suitability for serving as an anchor. In this way, the network may constrain an amount of network traffic associated with sidelink positioning procedures. However, this query-based procedure of the network transmitting information identifying a threshold, a UE responding with whether the threshold is satisfied, and the network initiating sidelink positioning procedures may use excessive network resources.

Some aspects described herein enable sidelink positioning anchor configuration. For example, a base station may provide information identifying a threshold for serving as an anchor and, when a first UE determines that location information of the first UE satisfies the threshold, the first UE may autonomously initiate a sidelink positioning procedure with other UEs. In this way, the base station may transmit information elements (IEs) updating the threshold to dynamically constrain which UEs can perform a sidelink position procedure, such as based at least in part on a quantity of UEs communicating in a network. In this way, the base station and the UEs in the network may avoid excessive utilization of network resources from performing a query-based procedure and excessive utilization of network resources from too many UEs attempting to serve as anchors (e.g., in a congested network) for sidelink positioning procedures.

FIG.6is a diagram illustrating an example600associated with sidelink positioning anchor configuration, in accordance with the present disclosure. As shown inFIG.6, example600includes communication between a base station110, a mobile station610-1, and a mobile station610-2. In some aspects, base station110and mobile stations610may be included in a wireless network, such as wireless network100. Base station110and mobile stations610may communicate via a wireless access link or a wireless sidelink as described in more detail herein.

As further shown inFIG.6, and by reference number650, mobile station610-1may receive first information identifying a value for a threshold parameter associated with a sidelink positioning procedure. For example, mobile station610-1may receive an indicator of a value for an anchoring threshold associated with a determination of whether a mobile station610is suitable for serving as an anchor for a sidelink positioning procedure. In some aspects, base station110may configure the value for the threshold parameter based at least in part on an amount of network congestion, a quantity of UEs communicating in a network, or another factor.

In some aspects, mobile station610-1may receive an indicator of a level of accuracy of a position determination by a mobile station610(e.g., mobile station610-1) that is to be achieved for the mobile station610to serve as an anchor for a sidelink positioning procedure. For example, mobile station610-1may receive an indication that, for mobile station610-1to serve as an anchor, mobile station610-1is to have determined an absolute position with a threshold accuracy. In this case, the threshold accuracy may be a threshold latitude location accuracy (e.g., in degrees latitude), a threshold longitude location accuracy (e.g., in degrees longitude), a threshold altitude location accuracy (e.g., in meters), or a combination thereof, among other examples. Additionally, or alternatively, the threshold accuracy may be associated with a temporal duration during which a threshold location accuracy is to be maintained. For example, base station110may indicate that for mobile station610-1to serve as an anchor, mobile station110-1is to have maintained a threshold latitude or longitude location accuracy for a threshold amount of time (e.g., in seconds). In some aspects, mobile station610may receive, from base station110, information identifying a coordinate location, such as in a LocationCoordinates parameter, as defined with regard to 3GPP Technical Specification (TS)37.355.

In some aspects, base station110may transmit the information indicating the value for the threshold parameter in an information element. For example, mobile station610-1may receive an information element in a system information block (SIB) message (e.g., an information element in a SIB type 12 (SIB12)), such as a sidelink UE selected configuration (SL-UE-SelectedConfig-r16) information element, which may include other information elements for other purposes. In this case, the information element may include a parameter identifying a sidelink position anchor accuracy (SL-PositionAnchor Accuracy) that mobile station610-1is to achieve with respect to one or more types of location accuracy or with respect to a duration, as described herein. Additionally, or alternatively, mobile station610-1may receive a SIB including an information element defined for conveying a sidelink position anchor accuracy parameter (SL-UE-PositioningConfig-r16) that is defined to include only one or more information elements relating to configuring sidelink positioning.

In some aspects, base station110may transmit the information indicating the value for the threshold parameter in a radio resource control (RRC) message. For example, base station110may configure an information element in an RRC message that is defined for other purposes. In this case, a type of RRC reconfiguration message, such as an RRC sidelink dedicated configuration (SL-ConfigDedicatedNR), may include the sidelink UE selected configuration (SL-UE-SelectedConfig-r16). Additionally, or alternatively, base station110may set a dedicated information element, in an RRC message (e.g., an RRC reconfiguration message), which is configured for conveying information relating to configuring sidelink positioning.

In some aspects, base station110may transmit the information indicating the value for the threshold parameter in a sidelink preconfiguration. For example, base station110may include a value for the threshold parameter among pre-configuration parameters by including the sidelink UE selected configuration (SL-UE-SelectedConfig-r16) in a sidelink dedicated configuration (SL-ConfigDedicatedNR-r16). Additionally, or alternatively, base station110may set a dedicated information element, in a preconfiguration, which is configured for conveying information relating to configuring sidelink positioning.

In some aspects, base station110may transmit the information indicating the value for the threshold parameter in another type of message. For example, base station110may configure a medium access control (MAC) control element (CE) to identify the threshold parameter. In this case, the MAC CE may be a MAC CE that is configured for other purposes or a dedicated MAC CE.

As further shown inFIG.6, and by reference number660, mobile stations610-1and610-2may communicate to perform a sidelink positioning procedure. For example, mobile station610-1may determine that positioning information stored by mobile station610-1satisfies a threshold accuracy and may transmit second information (e.g., to mobile station610-2) indicating that mobile station610-1may serve as an anchor for the sidelink positioning procedure. In this case, as described herein, mobile station610-1and mobile station610-2may transmit PRSs, among other signaling, to enable mobile station610-2to determine an absolute position based at least in part on information received from mobile station610-1and/or other mobile stations. In some aspects, mobile station610-1may initiate a sidelink positioning procedure based at least in part on determining that mobile station610-1can serve as an anchor for the sidelink positioning procedure.

Additionally, or alternatively, mobile station610-1may determine that positioning information stored by mobile station610-1does not satisfy the threshold accuracy. In this case, mobile station610-1may transmit second information indicating that mobile station610-1cannot serve as an anchor for the sidelink positioning procedure. In this case, mobile stations610-1and610-2may identify another mobile station that can serve as an anchor or may determine a relative position without an anchor.

In some aspects, mobile station610-1may periodically update whether mobile station610-1can serve as an anchor for a sidelink positioning procedure. For example, when a location accuracy of mobile station610-1changes (e.g., from better than a threshold accuracy to worse than the threshold accuracy), mobile station610-1may transmit a message (e.g., an RRC message or a MAC CE) with an information element (e.g., an information element in a sidelink UE information message (SidelinkUEInformationNR)) identifying a change to the location accuracy (e.g., in a sidelink position anchor accuracy information element (sl-PositionAnchorAccuracy)).

The foregoing disclosure provides illustration and description but is not intended to be exhaustive or to limit the aspects to the precise forms disclosed. Modifications and variations may be made in light of the above disclosure or may be acquired from practice of the aspects.

As used herein, the term “component” is intended to be broadly construed as hardware and/or a combination of hardware and software. “Software” shall be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software modules, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, and/or functions, among other examples, whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise. As used herein, a “processor” is implemented in hardware and/or a combination of hardware and software. It will be apparent that systems and/or methods described herein may be implemented in different forms of hardware and/or a combination of hardware and software. The actual specialized control hardware or software code used to implement these systems and/or methods is not limiting of the aspects. Thus, the operation and behavior of the systems and/or methods are described herein without reference to specific software code, since those skilled in the art will understand that software and hardware can be designed to implement the systems and/or methods based, at least in part, on the description herein.

As used herein, “satisfying a threshold” may, depending on the context, refer to a value being greater than the threshold, greater than or equal to the threshold, less than the threshold, less than or equal to the threshold, equal to the threshold, not equal to the threshold, or the like.

Even though particular combinations of features are recited in the claims and/or disclosed in the specification, these combinations are not intended to limit the disclosure of various aspects. Many of these features may be combined in ways not specifically recited in the claims and/or disclosed in the specification. The disclosure of various aspects includes each dependent claim in combination with every other claim in the claim set. As used herein, a phrase referring to “at least one of” a list of items refers to any combination of those items, including single members. As an example, “at least one of: a, b, or c” is intended to cover a, b, c, a+b, a+c, b+c, and a+b+c, as well as any combination with multiples of the same element (e.g., a+a, a+a+a, a+a+b, a+a+c, a+b+b, a+c+c, b+b, b+b+b, b+b+c, c+c, and c+c+c, or any other ordering of a, b, and c).

No element, act, or instruction used herein should be construed as critical or essential unless explicitly described as such. Also, as used herein, the articles “a” and “an” are intended to include one or more items and may be used interchangeably with “one or more.” Further, as used herein, the article “the” is intended to include one or more items referenced in connection with the article “the” and may be used interchangeably with “the one or more.” Furthermore, as used herein, the terms “set” and “group” are intended to include one or more items and may be used interchangeably with “one or more.” Where only one item is intended, the phrase “only one” or similar language is used. Also, as used herein, the terms “has,” “have,” “having,” or the like are intended to be open-ended terms that do not limit an element that they modify (e.g., an element “having” A may also have B). Further, the phrase “based on” is intended to mean “based, at least in part, on” unless explicitly stated otherwise. Also, as used herein, the term “or” is intended to be inclusive when used in a series and may be used interchangeably with “and/or,” unless explicitly stated otherwise (e.g., if used in combination with “either” or “only one of”).
