[Background technology]

[0002] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasts, and the like. These systems may be capable of supporting communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth generation (4G) systems, such as Long Term Evolution (LTE), LTE Advanced (LTE-A), or LTE-A Pro systems, and fifth generation (5G) systems, sometimes referred to as New Radio (NR) systems. These systems may employ technologies such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), or Discrete Fourier Transform Spread Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include several base stations or network access nodes, each simultaneously supporting communication for multiple communication devices, sometimes also known as user equipment (UE).

[0003] In some wireless communications systems, a positioning engine, e.g., a location server, or UE may determine the position or location of a supported UE using positioning measurements derived, for example, from base stations in a wireless network to which the UE is connected. This information may be associated with the UE based on UE-based or UE-assisted positioning techniques. These methods may support various location services (e.g., navigation systems, emergency communications) and may augment one or more additional location systems (such as Global Positioning System (GPS) technology) supported by the wireless communications device.

[0023] The detailed description set forth below with reference to the accompanying drawings is intended as a description of various configurations and does not represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details for providing a thorough understanding of the various concepts. However, it will be apparent to those skilled in the art that these concepts may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form to avoid obscuring such concepts.

[0024] The techniques described herein may be used for various wireless communication networks such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single Carrier FDMA (SC-FDMA) and other networks. The terms "network" and "system" are often used interchangeably. A CDMA network may implement a radio technology such as Universal Terrestrial Radio Access (UTRA), cdma2000, etc. UTRA includes Wideband CDMA (WCDMA), and other variants of CDMA. cdma2000 covers IS-2000, IS-95, and IS-856 standards. A TDMA network may implement a radio technology such as Global System for Mobile Communications (GSM). An OFDMA network may implement radio technologies such as Evolved UTRA (E-UTRA), Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDMA, etc. UTRA and E-UTRA are parts of the Universal Mobile Telecommunications System (UMTS). 2GPP Long Term Evolution (LTE) and LTE-Advanced (LTE-A) are new releases of UMTS that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A, and GSM are described in documents from an organization named "3rd Generation Partnership Project" (3GPP®). CDMA2000 and UMB are described in documents from an organization named "3rd Generation Partnership Project 2" (3GPP2). The techniques described herein may be used for the wireless networks and radio technologies mentioned above, as well as other wireless networks and radio technologies, such as next generation (e.g., Fifth Generation (5G) New Radio (NR) networks operating in the mmWave bands).

[0025] Several aspects of a telecommunications system are now presented with reference to various apparatus and methods that are described in the detailed description that follows and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using electronic hardware, computer software, or any combination thereof. Whether such elements are implemented as hardware or software depends on the particular application and design constraints imposed on the overall system.

[0026] As an example, an element, or any portion of an element, or any combination of elements, may be implemented as a "processing system" including one or more processors. Examples of processors include microprocessors, microcontrollers, graphics processing units (GPUs), central processing units (CPUs), application processors, digital signal processors (DSPs), reduced instruction set computing (RISC) processors, systems on chips (SoCs), baseband processors, field programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gate logic, discrete hardware circuits, and other suitable hardware configured to perform various functions described throughout this disclosure. One or more processors in a processing system may execute software. Software shall be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software components, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, and the like, whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise.

[0027] Thus, in one or more exemplary embodiments, the functions described may be implemented in hardware, software, or any combination thereof. If implemented in software, the functions may be stored on a computer-readable medium or encoded as one or more instructions or codes on a computer-readable medium. A computer-readable medium includes a computer storage medium. A storage medium may be any available medium that can be accessed by a computer. By way of example and not limitation, such a computer-readable medium may comprise a random access memory (RAM), a read-only memory (ROM), an electrically erasable programmable ROM (EEPROM), optical disk storage, magnetic disk storage, other magnetic storage devices, combinations of the above types of computer-readable media, or any other medium that can be used to store computer-executable code in the form of instructions or data structures that can be accessed by a computer.

[0028] To meet the growing demand for enhanced connectivity, wireless communication technologies or RATs are evolving from LTE technology, sometimes referred to as 4G, to next-generation NR technology, sometimes referred to as 5G NR. For example, 5G NR may provide lower latency and greater bandwidth or throughput than LTE. 5G NR is beginning to be deployed in markets where LTE is established. Deployment of 5G NR using both re-farmed and new frequency bands is being considered.

[0029] A mechanism that can be used to accelerate the deployment of 5G NR into markets already served by LTE is downlink (DL) spectrum sharing in the time or frequency domain. Sharing of DL spectrum can be dynamic, e.g., based on LTE and 5G NR traffic distribution, and may be referred to as dynamic spectrum sharing (DSS). DSS allows 5G NR to be effectively deployed and coexist with 4G LTE in the same frequency bands. Using DSS, mobile operators can flexibly allocate existing spectrum across frequency bands by dynamically switching between 4G LTE and 5G NR coverage based on traffic demand.

[0030] The use of DSS provides several benefits. For example, multiplexing of resources in the time or frequency domain can improve bandwidth utilization efficiency. With DSS, the time that a UE can utilize 5G NR can be increased, thereby minimizing the utilization of inter-radio access technology (IRAT) for handover to LTE. Furthermore, LTE networks generally have excess capacity, and therefore the impact of DSS on LTR can be minimized. In addition, without LTE refarming, there is a lack of low-band frequencies for 5G NR, and there is limited 5G NR coverage in high-band frequencies.

[0031] Current implementations of DSS effectively handle periodically scheduled signal types, such as cell-specific reference signals (CRS) in LTE and physical downlink shared channels (PDSCH) in 5G NR. However, one type of LTE signal that is not periodically scheduled and is specifically configured as needed is the positioning reference signal (PRS). Because PRS is configured as needed and is not a periodically scheduled signal type, current LTE-NR DSS techniques cannot accommodate PRS.

[0032] For example, implementations are described herein to allow continued use of PRS for positioning in LTE on shared frequency bands in which LTE and 5G NR are deployed using DSS.

[0033] 1 illustrates an example of a wireless communication system 100 including multiple separate wireless networks. The wireless communication system (also referred to as a wireless wide area network (WWAN)) includes a base station 102, a UE 104, an evolved packet core (EPC) 160 (sometimes referred to as an LTE network 160), and a 5G core (5GC) network 190 (sometimes referred to as a 5G NR network 190). The base station 102 may include a macro cell (high power cellular base station) and / or a small cell (low power cellular base station). The macro cell includes a base station. The small cell includes a femto cell, a pico cell, and a micro cell.

[0034] A base station 102 configured for 4G LTE (collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) may interface with the EPC 160 through a backhaul link 132 (e.g., an S1 interface). A base station 102 configured for 5G NR (collectively referred to as Next Generation RAN (NG-RAN)) may interface with the 5GC 190 through a backhaul link 184 (e.g., an N2, N3, or other interface). In addition to other functions, the base stations 102 may perform one or more of the following functions: forwarding user data, encryption and decryption of radio channels, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity), inter-cell interference coordination, connection setup and release, load balancing, distribution for non-access stratum (NAS) messages, NAS node selection, synchronization, radio access network (RAN) sharing, multimedia broadcast multicast service (MBMS), subscriber and equipment tracking, RAN information management (RIM), paging, positioning, and delivery of alert messages. Base stations 102 in the same wireless network may communicate with each other directly or indirectly (e.g., through EPC 160 or 5GC 190) via backhaul links 134 (e.g., X2, Xn, or other interfaces) either directly or indirectly (e.g., via a core network or intermediate base station). The backhaul links 134 may be wired or wireless.

[0035] The base stations 102 may wirelessly communicate with the UE 104. Each of the base stations 102 may provide communication coverage in a respective geographic coverage area 110. There may be overlapping geographic coverage areas 110. For example, a small cell 102' may have a coverage area 110' that overlaps with the coverage area 110 of one or more macro base stations 102. A network including both small cells and macro cells may be referred to as a heterogeneous network. A heterogeneous network may also include a Home evolved Node B (eNB) (HeNB) that may serve restricted groups called Closed Subscriber Groups (CSGs). A communication link 120 between the base station 102 and the UE 104 may include an uplink (UL) (also referred to as a reverse link) transmission from the UE 104 to the base station 102, and / or a downlink (DL) (also referred to as a forward link) transmission from the base station 102 to the UE 104. The communication link 120 may use multiple-input multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming, and / or transmit diversity. The communication link may be through one or more carriers. The base station 102 / UE 104 may use spectrum with bandwidth up to Y MHz (e.g., 5, 10, 15, 20, 100, 400 MHz, etc.) per carrier allocated in carrier aggregation with up to a total of Yx MHz (x component carriers) used for transmission in each direction. The carriers may or may not be adjacent to each other. The carrier allocation may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated for DL ​​than for UL). The component carriers may include a primary component carrier and one or more secondary component carriers. The primary component carrier may be referred to as a primary cell (PCell), and the secondary component carrier may be referred to as a secondary cell (SCell).

[0036] The term "cell" refers to a logical communication entity used for communication with a base station 102 (e.g., on a carrier) and may be associated with an identifier (e.g., physical cell identifier (PCID), virtual cell identifier (VCID)) to distinguish neighboring cells operating over the same or different carriers. In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., machine type communications (MTC), narrowband Internet of Things (NB-IoT), enhanced mobile broadband (eMBB), or others) that may provide access for different types of devices. In some examples, the term "cell" may refer to a portion of a geographic coverage area 110 (e.g., a sector) over which a logical entity operates.

[0037] Several UEs 104 may communicate with each other using device-to-device (D2D) communication links 158. The D2D communication links 158 may use DL / UL WWAN spectrum. The D2D communication links 158 may use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH), a physical sidelink discovery channel (PSDCH), a physical sidelink shared channel (PSSCH), and a physical sidelink control channel (PSCCH). The D2D communication may be through various wireless D2D communication systems, such as, for example, FlashLinQ, WiMedia, Bluetooth, ZigBee, Wi-Fi based on IEEE 802.11 standards, LTE, or NR.

[0038] The wireless communication system may further include a Wi-Fi access point (AP) 150 in communication with a Wi-Fi station (STA) 152 via a communication link 154 in the 5 GHz unlicensed frequency spectrum. When communicating in the unlicensed frequency spectrum, the STA 152 / AP 150 may perform clear channel assessment (CCA) prior to communicating to determine if a channel is available.

[0039] The small cell 102' may operate in licensed and / or unlicensed frequency spectrums. When operating in the unlicensed frequency spectrum, the small cell 102' may employ NR and use the same 5 GHz unlicensed frequency spectrum used by the Wi-Fi AP 150. A small cell 102' employing NR in the unlicensed frequency spectrum may extend coverage to and / or increase capacity of an access network.

[0040] The base station 102, whether a small cell 102' or a large cell (e.g., a macro base station), may include an eNB, a g Node B (gNB), or another type of base station. Some base stations, such as the gNB 180, may communicate with the UE 104 and operate in the conventional sub-6 GHz spectrum, at millimeter wave (mmW) frequencies, and / or at sub-mmW frequencies. When the gNB 180 operates at mmW or sub-mmW frequencies, it may be referred to as a millimeter wave or mmW base station. Extremely high frequency (EHF) is a part of RF in the electromagnetic spectrum. EHF ranges from 20 GHz to 200 GHz and has a wavelength between 1 millimeter and 10 millimeters. Radio waves in that band may be referred to as millimeter waves. Sub-mmW may extend downwards to frequencies of 2 GHz with wavelengths of 100 millimeters. The very high frequency (SHF) band, also called centimeter wave, extends between 2 GHz and 20 GHz. Communications using mmW / sub-mmW radio frequency bands (e.g., 2 GHz to 200 GHz) have very high path losses and short distances. The mmW base station 180 may utilize beamforming 182 with the UE 104 to compensate for the very high path losses and short distances.

[0041] The base station 180 may transmit a beamformed signal to the UE 104 in one or more transmit directions 182′. The UE 104 may receive a beamformed signal from the base station 180 in one or more receive directions 182″. The UE 104 may also transmit a beamformed signal to the base station 180 in one or more transmit directions. The base station 180 may receive a beamformed signal from the UE 104 in one or more receive directions. The base station 180 / UE 104 may perform beam training to determine the best receive direction and transmit direction for each of the base station 180 / UE 104. The transmit direction and receive direction for the base station 180 may be the same or different. The transmit direction and receive direction for the UE 104 may be the same or different.

[0042] The core network 160 / 190 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, positioning and other access functions, routing functions, or mobility functions.

[0043] The EPC 160 may include, by way of example, a Mobility Management Entity (MME) 162, an Enhanced Serving Mobile Location Center (E-SMLC) 164, a Serving Gateway 166, a Gateway Mobile Location Center (GMLC) 168, a Home Secure User Plane Location (SUPL) Location Platform (H-SLP) 170, and a Packet Data Network (PDN) Gateway 172. The MME 162 may be in communication with a Home Subscriber Server (HSS) 174. The MME 162 is a control node that handles signaling between the UE 104 and the EPC 160. In general, the MME 162 is responsible for bearer and connection management. The E-SMLC 164 may support UE location determination using, for example, a 3GPP control plane (CP) location solution. All user Internet Protocol (IP) packets are forwarded through the Serving Gateway 166, which itself is connected to the PDN Gateway 172. The PDN Gateway 172 provides UE IP address allocation as well as other functions. The PDN Gateway 172 is connected to IP Services 176. The IP Services 176 may include the Internet, an Intranet, an IP Multimedia Subsystem (IMS), PS streaming services, and / or other IP services. The GMLC 168 may provide the UE with access to location information, for example, on behalf of an external client 169, which may be within or outside the IP Services 176. The H-SLP 170 may support the SUPL User Plane (UP) location solution defined by the Open Mobile Alliance (OMA) and may support location services for the UE based on the UE's subscriber information stored in the H-SLP 170.

[0044] The 5GC 190 may include, by way of example, an Access and Mobility Management Function (AMF) 192, a Gateway Mobile Location Center (GMLC) 193, a Session Management Function (SMF) 194, a User Plane Function (UPF) 195, and a Location Management Function (LMF) 196. The AMF 192 may communicate with a Unified Data Management (UDM) 197. The AMF 192 is a control node that handles signaling between the UE 104 and the 5GC 190, which may communicate with the LMF 196 for positioning functions, which may support location determination of the UE. In some implementations, the LMF 196 may be co-located with the base station 105 in the NG-RAN and may be referred to as a Location Management Component (LMC). The GMLC 193 may be used to enable an external client 199 outside or within the IP service 198 to receive location information regarding the UE. All user Internet Protocol (IP) packets may be forwarded through the UPF 195. The UPF 195 provides IP address allocation for the UE as well as other functions. The UPF 195 is connected to IP services 198. The H-SLP 191 may be similarly connected to IP services 198. The IP services 198 may include the Internet, an intranet, an IP Multimedia Subsystem (IMS), PS streaming services, and / or other IP services.

[0045] A base station may also be referred to as a gNB, Node B, evolved Node B (eNB), access point, base transceiver station, radio base station, radio transceiver, transceiver function, basic service set (BSS), enhanced service set (ESS), transmission / reception point (TRP), or some other suitable terminology. The base station 102 provides an access point to the EPC 160 or 5GC 190 for the UE 104. Examples of the UE 104 include a cellular phone, a smartphone, a session initiation protocol (SIP) phone, a laptop, a personal digital assistant (PDA), a satellite radio, a global positioning system, a multimedia device, a video device, a digital audio player (e.g., MP3 player), a camera, a game console, a tablet, a smart device, a wearable device, a vehicle, an electric meter, a gas pump, a large or small cooking appliance, a health management device, an implant, a sensor / actuator, a display, or any other similar function device. Some of the UEs 104 may be referred to as IoT devices (e.g., a parking meter, a gas pump, a toaster, a vehicle, a heart monitor, etc.). Some of the UEs 104 may be referred to as Industrial Internet of Things (IIoT) devices, such as sensors, instruments, and other networked devices in industrial applications. The UEs 104 may also be referred to as stations, mobile stations, subscriber stations, mobile units, subscriber units, wireless units, remote units, mobile devices, wireless devices, wireless communication devices, remote devices, mobile subscriber stations, access terminals, mobile terminals, wireless terminals, remote terminals, handsets, user agents, mobile clients, clients, or some other suitable terminology.

[0046] The UE 104 can enter into a connected state with a wireless communication network that may include a base station 102 for position determination. In one example, the UE 104 may communicate with a cellular communication network by transmitting wireless signals to or receiving wireless signals from a cellular base station. In another example, the UE 104 may communicate with a base station for a local area network (LAN), such as a Wi-Fi access point or other wireless network.

[0047] In a particular implementation, the UE 104 may have circuitry and processing resources capable of obtaining location-related measurements. The location-related measurements obtained by the UE 104 may include measurements of signals received from satellite vehicles belonging to a satellite positioning system (SPS) or a global navigation satellite system (GNSS), such as GPS, GLONASS, Galileo, or Beidou, and / or may include positioning values ​​of signals received from a terrestrial base station (e.g., such as the base station 102 of FIG. 1) fixed at a known location. The UE 104 or a location server (e.g., E-SMLC 164, H-SLP 170, or LMF 196) to which the UE 104 may send the measurements may then obtain a location estimate for the UE 104 based on these location-related measurements using any one of a number of positioning methods, such as, for example, GNSS, Assisted GNSS (A-GNSS), Advanced Forward Link Trilateration (AFLT), Observed Time Difference of Arrival (OTDOA), WLAN (also called WiFi) positioning, Angle of Departure (AOD), Angle of Arrival (AOA), Multi-Cell Round Trip Signal Propagation Time (multi-RTT), Extended Cell ID (ECID), or a combination thereof. In some of these techniques (e.g., A-GNSS, AFLT, and OTDOA), pseudoranges or timing differences may be measured at the UE 104 to three or more terrestrial base stations 102 fixed at known locations based at least in part on pilots, positioning reference signals (PRS), or other positioning-related signals transmitted by the base stations 102 and received at the UE 104.

[0048] In some examples, the base station 102 may transmit downlink positioning, such as a PRS or tracking reference signal. The positioning signal transmission may be configured for a particular UE 104 to measure one or more parameters to use as part of a UE-based positioning technique or to report as part of a UE-assisted positioning technique. Similarly, the UE 104 may transmit a positioning signal, such as an uplink PRS or sounding reference signal, and the base station 102 may measure one or more parameters to be used as part of a UE-based side technique or as part of a UE-assisted positioning technique. The PRS transmission and reporting parameter feedback may support various location services (e.g., navigation systems, emergency communications). In some examples, the reporting parameters augment one or more additional location determination systems (such as Global Positioning System (GPS) technology) supported by the UE 104.

[0049] The base station 102 may configure a PRS transmission on one or more PRS resources of the channel. The PRS resource may span resource elements of multiple physical resource blocks (PRBs) in one or more OFDM symbols of the slot depending on the configured number of ports. For example, a PRS resource may span one symbol of the slot and include one port for transmission. In any OFDM symbol, the PRS resource may occupy consecutive PRBs. In some examples, the PRS transmission may be mapped to consecutive OFDM symbols of the slot. In other examples, the PRS transmission may be mapped to interspersed OFDM symbols of the slot. In addition, the PRS transmission may support frequency hopping within the PRB of the channel.

[0050] Aspects of the wireless communication system 100 may include the use of PRS transmissions by the base stations 102 or Sounding Reference Signal (SRS) transmissions by the UE 104 for UE location determination. For downlink-based UE location determination, a location server, e.g., a Location Management Function (LMF) in an NR network or a Secure User Plane Location (SUPL) Location Platform (SLP) in LTE, may be used to provide positioning assistance, such as PRS assistance data (AD), to the UE 104. In UE-assisted positioning, the location server may receive measurement reports from the UE 104 indicating location measurements of one or more base stations 102, which the location server may use to determine a location estimate for the UE 104, e.g., using OTDOA or other desired techniques.

[0051] As discussed above, DSS can be used to flexibly allocate existing spectrum across frequency bands, for example, by dynamically switching between 4G LTE and 5G NR coverage based on traffic demand.

[0052] 2 shows a block diagram of a design 200 of a base station 102 and a UE 104, which may be one of the base stations and one of the UEs in FIG. 1. The base station 102 may be equipped with T antennas 234a through 234t, and the UE 104 may be equipped with R antennas 252a through 252r, where in general T≧1 and R≧1.

[0053] At the base station 102, the transmit processor 220 may receive data for one or more UEs from a data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS selected for the UE, and provide data symbols to all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI), etc.) and control information (e.g., CQI requests, grants, higher layer signaling, etc.) and provide overhead and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS)) and synchronization signals (e.g., primary synchronization signals (PSS) and secondary synchronization signals (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​the data symbols, control symbols, overhead symbols, and / or reference symbols, if applicable, and may provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively. According to various aspects described in more detail below, a synchronization signal may be generated using location coding to convey additional information.

[0054] At the UE 104, the antennas 252a-252r may receive downlink signals from the base station 102 and / or other base stations, respectively, and may provide received signals to demodulators (DEMODs) 254a-254r. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. A MIMO detector 256 may 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 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for the UE 104 to a data sink 260, and provide decoded control and system information to the controller / processor 280. The channel processor may determine a reference signal received power (RSRP), a received signal strength indicator (RSSI), a reference signal received quality (RSRQ), a channel quality indicator (CQI), etc. In some aspects, one or more components of the UE 104 may be included within a housing.

[0055] On the uplink, at the UE 104, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports comprising RSRP, RSSI, RSRQ, CQI, etc.) from the controller / processor 280. The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 if applicable, further processed by modulators 254a-254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to the base station 102. At the base station 102, uplink signals from the UE 104 and other UEs may be received by the antennas 234, processed by the demodulator 232, detected by a MIMO detector 236 if applicable, and further processed by the receive processor 238 to obtain decoded data and control information sent by the UE 104. The receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to the controller / processor 240. The base station 102 may include a communication unit 244 and may communicate with the network controller 160 / 190 via the communication unit 244. The network controller 160 / 190 may include a communication unit 294, a controller / processor 290, and a memory 292.

[0056] The controller / processor 240 of the base station 102, the controller / processor 280 of the UE 104, and / or any other components of FIG. 2 may perform one or more techniques related to the reception of NR data and control signals by the UE 104 while the LTE PRS is transmitted on the shared spectrum using DSS, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 102, the controller / processor 280 of the UE 104, and / or any other components of FIG. 2 may perform or direct the operation of, for example, processes 800, 900, 1000, and 1100 of FIGS. 8-11, and / or other processes as described herein. The memory 242 and the memory 282 may store data and program codes for the base station 102 and the UE 104, respectively. In some aspects, the memory 242 and / or the memory 282 may comprise a non-transitory computer-readable medium that stores one or more instructions for wireless communication. For example, the one or more instructions, when executed by one or more processors at the base station 102 and / or the UE 104, may perform or direct operation of, for example, processes 800, 900, 1000, and 1100 of Figures 8-11 and / or other processes as described herein. The scheduler 246 may schedule UEs for NR data and control transmissions on the downlink and / or uplink based on the LTE PRS rate matching pattern and / or the LTE PRS muting pattern.

[0057] As noted above, Figure 2 is provided as an example. Other examples may differ from those described with respect to Figure 2.

[0058] 5G NR networks are beginning to be deployed in areas where LTE networks are already established. Instead of acquiring new spectrum or refarming spectrum already in use, 5G NR can be adapted to coexist with LTE using the same spectrum using DSS. Using DSS, NR data and control signals can be transmitted on occupied frequency channels used by LTE networks, but in a manner that has little impact on the performance of the LTE network.

[0059] For example, multimedia broadcast signal frequency network (MBSFN) subframes may be used to provide gaps necessary for transmission of synchronization signal blocks (SSBs) used by the NR UE 104 to maintain synchronization in time and frequency with the 5G NR network 190.

[0060] 3A illustrates an MBSFN subframe 300 shared by an LTE network 160 and a 5G NR network 190 using, for example, NR SSBs. However, the use of the MBSFN subframe is limited. For example, to limit the impact on LTE performance, the MBSFN subframe may be limited to a single subframe.

[0061] Thus, DSS also enables the use of subframes that are LTE-only and not configured for MBSFN for 5G NR data and control messages. Standard LTE subframes include a cell-specific reference signal (CRS) that is mapped to certain resource elements. LTE-connected UEs use the CRS for channel estimation and to maintain time and frequency synchronization. Even during subframes where LTE data is not scheduled, the LTE CRS will still be present. Rate matching around the LTE CRS is used to enable 5G NR to use subframes with LTE CRS.

[0062] FIG. 3B illustrates a non-MBSFN subframe 350 that includes, for example, an LTE CRS and NR data (PDSCH) that is rate-matched around the LTE CRS. The LTE CRS is a periodically transmitted transmission, and therefore only a few factors influence the rate-matching algorithm. For example, the offset to the subcarrier alignment and the number of antenna ports must be known. In addition, since the CRS is cell-specific, another factor for rate-matching LTE CRS is v, which represents the influence of the physical cell identity (PCI), which defines the starting point (subcarrier) for the mapping of the LTR sequence used to generate the CRS. shift (v shift = PCI mod 6). These coefficients may be communicated to the NR UE 104, for example, using a radio resource control (RRC) connection. Because these coefficients do not change over time, the NR UE 104 may perform rate matching around the LTE CRS rate in each subframe as long as the NR UE 104 is connected to the same cell.

[0063] MBSFN subframe 300 and non-MBSFN subframe 350 show specific subframes that may be used for NR when LTE is not present, or mechanisms that allow NR to transmit in LTE subframes that are not used by LTE but in which essential LTE signal components, e.g., LTE CRS, are still sent. DSS additionally allows LTE and NR to share subframes in which they both transmit control information (PDCCH and CORESET) and data (PDSCH). For example, dynamic sharing of subframes is possible by coordinating scheduling resources in the frequency and time domains at the medium access control layer in both base stations for the LTE network and the 5G NR network 190.

[0064] FIG. 3C illustrates a wireless communication system 370 including a base station 372, e.g., an eNB, for an LTE network, a base station 374, e.g., a gNB, for a 5G NR network, and an NR UE 104. The eNB 372 and the gNB 374 share the same spectrum using DSS. As indicated by arrow 376, the NR UE 104 is connected to the gNB 374 to wirelessly receive NR control and data signals. Because the gNB 374 and the eNB 372 share spectrum via DSS, the eNB 372 transmits a signal 378 on a frequency to which the NR UE 104 is tuned. In addition to using the MBSFN subframes 300 and non-MBSFN subframes 350 discussed above to enable coexistence of NR and LTE on the same spectrum, the gNB 374 and the eNB 372, operating with independent schedulers, may cooperate in a dual connectivity manner over the Xn interface 380. For example, the gNB 374 and the eNB 372 may coordinate using a bitmap that provides a data traffic resource indication indicating which PRBs are reserved for LTE or not.

[0065] As discussed, the LTE CRS is a periodically transmitted signal that does not change, so the LTE CRS can be easily processed using DSS. However, the LTE PRS signal is not periodically transmitted and can be configured as needed. Thus, current DSS techniques cannot accommodate the LTE PRS.

[0066] FIG. 4 illustrates a structure of an example subframe sequence 400 having a positioning reference signal (PRS) positioning occasion according to an embodiment of the present disclosure. The subframe sequence 400 may be applicable to broadcasting a PRS signal from a base station (e.g., any of the base stations described herein) or other network node. The subframe sequence 400 may be used in an LTE system, and the same or similar subframe sequence may be used in other communication technologies / protocols, such as 5G and NR. In FIG. 4, time is represented horizontally (e.g., on the X-axis), with time increasing from left to right, while frequency is represented vertically (e.g., on the Y-axis), with frequency increasing (or decreasing) from bottom to top. As shown in FIG. 4, the downlink and uplink radio frames 410 may each be of 10 milliseconds (ms) in duration. In a downlink frequency division duplex (FDD) mode, in the illustrated example, the radio frame 410 is organized into 10 subframes 412, each of 1 ms in duration. Each subframe 412 comprises two slots 414, each of duration 0.5 ms, for example.

[0067] In the frequency domain, the available bandwidth may be divided into uniformly spaced orthogonal subcarriers 416 (also called "tones" or "bins"). For example, with a regular length cyclic prefix (CP), using, for example, 15 kHz spacing, the subcarriers 416 may be grouped into groups of 12 subcarriers. The resource of one OFDM symbol length in the time domain and one subcarrier in the frequency domain (represented as a block of subframes 412) is called a resource element (RE). Each grouping of 12 subcarriers 416 and 14 OFDM symbols is called a resource block (RB), and in the above example, the number of subcarriers in a resource block is

[0068]

number

[0069] For a given channel bandwidth, the number of available resource blocks on each channel 422, also called the transmission bandwidth configuration 422, is written as

[0070]

number

[0071] For example, for a 2 MHz channel bandwidth in the above example, the number of available resource blocks on each channel 422 is

[0072]

number

[0073] Note that the frequency components of a resource block (e.g., 12 subcarriers) are called a physical resource block (PRB).

[0074] A base station may transmit radio frames (e.g., radio frame 410), or other physical layer signaling sequences, and support PRS signals (i.e., downlink (DL) PRS) according to a frame configuration that is either similar to or the same as that shown in Figure 4, which may be measured and used for location estimation of a UE (e.g., any of the UEs described herein). Other types of wireless nodes in a wireless communications network (e.g., distributed antenna systems (DAS), remote radio heads (RRHs), UEs, APs, etc.) may also be configured to transmit PRS signals configured in a manner similar to (or the same as) that shown in Figure 4.

[0075] A collection of resource elements used for transmission of a PRS signal is called a "PRS resource." The collection of resource elements may span multiple PRBs in the frequency domain and N (e.g., one or more) consecutive symbols in a slot 414 in the time domain. For example, the cross-hatched resource elements in a slot 414 may be an example of two PRS resources. A "PRS resource set" is a set of PRS resources used for transmission of a PRS signal, and each PRS resource has a PRS resource identifier (ID). In addition, the PRS resources in a PRS resource set are associated with the same transmission / reception point (TRP). A PRS resource ID in a PRS resource set is associated with a single beam transmitted from a single TRP (if a TRP may transmit one or more beams). Note that this does not have any indication as to whether the TRP and beam from which the signal is transmitted are known to the UE.

[0076] The PRS may be transmitted in special positioning subframes that are grouped into positioning occasions. A PRS occasion is one instance of a regularly repeated time period (e.g., consecutive slots) in which a PRS is expected to be transmitted. Each regularly repeated time period may contain a group of one or more consecutive PRS occasions. Each PRS occasion may be grouped into a certain number (N PRS The PRS positioning occasions of the cells supported by the base station may comprise a number of consecutive positioning subframes T PRS For example, FIG. 4 shows a PRS is equal to 4 (418), T PRS is greater than or equal to 20 (420). PRS may be measured in terms of the number of subframes between the starts of successive positioning occasions. Multiple PRS occasions may be associated with the same PRS resource configuration, in which case each such occasion may be referred to as a "PRS resource occasion", etc.

[0077] The PRS may be transmitted at a constant power. The PRS may also be transmitted at zero power (i.e., muted). Muting, which turns off periodically scheduled PRS transmissions, may be useful when PRS signals between different cells overlap by occurring at or near the same time. In this case, PRS signals from some cells may be muted while PRS signals from other cells are transmitted (e.g., at a constant power). Muting may aid in signal acquisition and time of arrival (TOA) and reference signal time difference (RSTD) measurements of unmuted PRS signals by the UE (by avoiding interference from muted PRS signals). Muting may be viewed as not transmitting the PRS for a given positioning occasion for a particular cell. The muting pattern (also referred to as a muting sequence) may be signaled to the UE using a bit string (e.g., using the LTE Positioning Protocol (LPP)). For example, if a bit at location j is set to '0' in a bit string signaled to indicate a muting pattern, the UE may infer that the PRS is muted for the jth positioning occasion.

[0078] To further enhance the audibility of the PRS, the positioning subframe may be a low-interference subframe transmitted without a user data channel. As a result, in an ideally synchronized network, the PRS may be interfered with by PRSs of other cells with the same PRS pattern index (i.e., with the same frequency shift), but not with data transmissions. The frequency shift may be used to reduce the interference between the PRSs of the cells or other transmission points (TPs) (

[0079]

number

[0080] ) as a function of the PRS ID, or the Physical Cell Identifier (PCI) (

[0081]

number

[0082] ), which yields an effective frequency reuse factor of 6.

[0083] Also to enhance PRS audibility (e.g., when the PRS bandwidth is limited, such as with only six resource blocks corresponding to a 1.4 MHz bandwidth), the frequency bands for successive PRS positioning occasions (or successive PRS subframes) may be changed in a known and predictable manner via frequency hopping. In addition, a cell supported by a base station may support more than one PRS configuration, where each PRS configuration may support a different frequency offset (vshift), a different carrier frequency, a different bandwidth, a different code sequence, and / or a certain number of subframes (N PRS ) and a specific period (T PRS In some implementations, one or more of the PRS configurations supported in a cell may be for directional PRS, which may have additional distinct characteristics, such as distinct directions of transmission, distinct horizontal angular ranges, and / or distinct vertical angular ranges.

[0084] The PRS may not be transmitted by all cells and may not be transmitted in all subframes. The PRS configuration as described above includes the PRS transmission / muting schedule and is signaled to the UE to enable the UE to perform PRS positioning measurements. The UE is not expected to blindly perform PRS configuration detection.

[0085] When a 5G NR network shares one or more frequency bands with an LTE network using DSS, periodic transmissions by the LTE network, such as CRS, or by the 5G NR network, such as PDSCH, are known and can be accommodated by DSS procedures. For example, the LTE CRS is a cell-specific reference signal that is mapped to resource elements that are spread across a resource grid in the same pattern in all resource blocks. Thus, the LTE CRS transmissions from a particular cell can be easily identified for each cell and accommodated by DSS procedures.

[0086] However, unlike the LTE CRS, the LTE PRS is not always transmitted by all cells, and when it is transmitted by a cell, the LTE PRS is not transmitted in all subframes. The PRS transmission is configuration-based, e.g., the PRS transmission occurs only in configured cells and in configured subframes, not in all subframes. Moreover, the mapping of the PRS to resource elements in the resource grid is configured. Thus, unlike the LTE CRS, the LTE PRS is not predictable and periodic, and cannot be accommodated by current DSS techniques. Without knowledge of the LTE PRS configuration, an NR UE 104 connected to a 5G NR network that shares spectrum with an LTE network using DSS will not know which cells are transmitting the PRS, or which subframes or which resource elements in each resource block are configured for the PRS. For example, referring to FIG. 3C, if the UE 104 is receiving a data or control signal from the gNB 374 while the eNB 372 is transmitting the LTE PRS in signal 378 without adapting to the LTE PRS, the UE 104 will not be able to properly decode the NR data or control signal in the subframe in which the LTE PRS is present.

[0087] Thus, in one implementation, LTE PRS scheduling information is provided to a UE 104 connected to a 5G NR network 190 such that the UE 104 may rate-match NR data around an LTE PRS transmission. For example, a scheduler in a base station 102 of a 5G NR network 190 may receive an LTE PRS configuration and provide an LTE PRS rate-matching pattern that provides LTE PRS scheduling information to the UE 104, and the UE may rate-match NR data using the LTE PRS rate-matching pattern. In some implementations, an LTE PRS configuration, such as one or more of a carrier frequency, a carrier bandwidth, a number of consecutive PRS subframes, a PRS periodicity, a PRS configuration index, a muting pattern, or a combination thereof, may be provided to the UE 104, and the UE 104 may determine a rate-matching scheme for data transmissions from the 5G NR network based on the received LTE PRS configuration and process data transmissions from the 5G network around the LTE PRS transmission. With knowledge of whether a subframe is configured to include LTE PRS transmissions and which subcarriers in the subframe are configured to include PRS transmissions, the UE 104 may puncture subcarriers or resource elements at a particular time with the LTE PRS and receive the remaining resource elements or subcarriers in the resource block. Thus, the UE 104 may rate-match NR data signals, such as PDSCH and PDCCH, around the LTE PRS transmission using the PRS rate-matching pattern. Because the LTE PRS is configured for a particular subframe, slot, and subcarrier with knowledge of the LTE PRS configuration, the UE 104 may puncture only the affected subframes, slots, and subcarriers to receive NR data. Moreover, the 5G NR network may schedule NR data, such as PDSCH and PDCCH, according to the LTE PRS configuration.

[0088] 5A and 5B, for example, illustrate an LTE subframe 500 and an NR subframe 550 rate-matched to the LTE subframe 500, respectively. The LTE subframe 500 includes an LTE PRS, and the NR subframe 550 includes NR data (PDSCH) rate-matched around the LTE PRS in the LTE subframe. The rate-matching around the LTE PRS may be based on the UE 104 receiving a rate-matching pattern from the 5G NR base station 102 and applying the rate-matching pattern to the subframe to receive the NR data. In another implementation, the UE 104 may receive an LTE PRS configuration from the 5G NR base station 102, determine a corresponding rate-matching pattern from the LTE PRS configuration, and apply the rate-matching pattern to the subframe to receive the NR data.

[0089] The UE 104 may provide its capability for rate matching around LTE PRS transmission to the 5G NR network. In some implementations, the 5G NR network may reject a connection setup for the UE 104 or use RRC connection release if LTE PRS transmission is configured for the frequency band in DSS mode and NR data cannot be scheduled without rate matching. For example, it may not be possible to schedule NR data due to either the four symbol SSB constraint or excessive overhead for NR data.

[0090] If the UE 104 does not have the capability to support PRS rate matching, the 5G NR network may schedule NR data restricted to multicast broadcast single frequency network (MBSFN) frames such that NR data is not scheduled in non-MBSFN frames.

[0091] In addition, the LTE network may adjust the muting pattern of the LTE PRS transmission according to a synchronization signal block (SSB) schedule of the 5G NR network, and the adjusted muting pattern may be shared with the UE 104 for rate matching accordingly in the muted subframes.

[0092] As an example, as shown in Table 1, which is part of Abstract Syntax Notation One (ASN.1), a UE 104 connected to a 5G NR network may include a capability to rate match LTE PRS transmissions. For example, as shown in the table, the UE includes a capability of "rateMatchingLTE-PRS."

[0093] [Table 1]

[0094] As shown in Tables 2 and 3, which are part of ASN.1, a 5G NR network may reuse rate match pattern lists to provide PRS scheduling information to the UE 104. For example, Table 2 indicates that the PDSCH configuration includes "rateMatchPatternToAddModList" and Table 3 indicates "RateMatchPattern."

[0095] [Table 2]

[0096] [Table 3]

[0097] As shown in Tables 4 and 5, which are part of ASN.1, the serving cell may be configured based on a PRS pattern for rate matching the NR PDSCH. For example, Table 4 indicates that the rate matching pattern LTE-CRS may include "RateMatchPatternLTE-PRS" and Table 5 indicates that the serving cell configuration may include "lte-PRS-ToMatchAround". As can be seen, the rate matching pattern for LTE-PRS includes, for example, a carrier DL frequency ("carrierFreqDL"), a carrier DL bandwidth ("carrierBandwidthDL"), a number of PRS (i.e., number of consecutive PRS subframes) ("NPRS"), a PRS period "TPRS", and a muting pattern ("MUTINGPATTERN"), as well as a PRS configuration index.

[0098] [Table 4]

[0099] [Table 5]

[0100] In addition to or as an alternative to rate-matching NR data around an LTE PRS transmission, a 5G NR base station may transmit NR data based on a muting pattern of an NR SSB and / or an LTE PRS with a constraint of being transmitted in four consecutive symbols, e.g., the NR SSB and / or data is transmitted in a subframe or slot while the LTE PRS is muted. For example, in some implementations, rate-matching around the LTE PRS may not be possible, e.g., the UE 104 may not be capable of rate-matching. In such a situation, a scheduler in the 5G NR network, e.g., the 5G NR base station 102, may schedule NR data transmission based on an LTE PRS muting schedule such that the NR data is transmitted while the LTE PRS is muted. In some implementations, the 5G NR base station may request the LTE base station to adjust its muting pattern, e.g., over an Xn interface, so that the NR data can be transmitted.

[0101] Due to the frequency difference, the 5G NR network 190 may require at least two consecutive symbols of an LTE subframe to transmit, for example, four consecutive OFDM symbols for SSB or NR data. For example, the 5G NR network may require at least two consecutive symbols in an LTE 15KHz subcarrier spacing (SCS) so that a 5G NR 30KHz SCS can be deployed in four consecutive OFDM symbols. However, due to the high density of LTE PRS along with other control signals transmitted, for example, LTE CRS, based on the SSB periodicity, two consecutive symbols may not be present in the LTE subframe or may require excessive overhead for NR data. Thus, the 5G NR network 190 may require the LTE network 160 to schedule an LTE PRS muting pattern, for example, through a scheduler in the respective base station via the Xn interface, to leave a subframe available for the 5G NR network 190 to schedule the SSB. For example, the scheduler of the 5G NR base station may provide the SSB schedule to the scheduler of the LTE base station. The LTE network 160 may adjust the LTE PRS muting pattern accordingly, e.g., the LTE PRS is muted such that SSB scheduling is possible in four consecutive OFDM symbols for a subframe or slot in which an SSB is scheduled.

[0102] Figure 6 illustrates an LTE subframe 600 including, for example, an LTE PRS and NR data (PDSCH) rate-matched around the LTE PRS. Figure 6 further illustrates a muted LTE PRS, for example, in symbols 5 and 10. As shown, by muting the LTE PRS in symbol 5, two consecutive symbols of the LTE subframe 600 are available for transmission of the SSB 602, which, due to the frequency difference, is equivalent to four consecutive OFDM symbols in the NR subframe. The LTE subframe 600 further illustrates an NR PDCCH in symbol 6.

[0103] Thus, LTE PRS and NR PDSCH, SSB and PDCCH can coexist using DSS and be supported without significantly impacting LTE positioning and sacrificing little additional overhead over the NR PDSCH.

[0104] FIG. 7 illustrates an example message flow 700 illustrating communication between various components of a wireless communication system, such as the wireless communication system 100 discussed with reference to FIG. 1, including multiple wireless networks supporting wireless communication with a UE 104 and a second UE 704 that may be similar to the UE 104. As previously mentioned, the techniques disclosed herein are not necessarily limited to the architecture illustrated in FIG. 1. As shown, a 5G NR network 702, which may be, for example, a cellular network such as the 5G NR network 190, includes a gNB 102-1 and a server 703, which may be, for example, the LMF 196 illustrated in FIG. 1. An LTE network 706, which may be, for example, the LTE network 160, includes an eNB 102-2. The gNB 102-1 in the 5G NR network 702 and the eNB 102-2 in the LTE network 706 share one or more frequency bands using DSS. The UE 104 is configured to connect to the 5G NR network 702, while the UE 704 is configured to connect to the LTE network 706. It should be understood that there may be one or more preliminary (and intervening) steps not shown in FIG. 7 to support, for example, conventional communications or communications between entities in the same network, e.g., between gNB102-1 and server 703 in 5G NR network 702.

[0105] In stage 1, the UE 104 may receive a capability request to a server 703 of the 5G NR network 702. The capability request may, for example, request the UE 104 the capability to support DSS.

[0106] In stage 2, the UE 104 may provide a capability response to the server 703. For example, the UE 104 may indicate that the UE 104 can support DSS. The UE 104 may further indicate whether the UE 104 can support rate matching around the LTE PRS.

[0107] In stage 3, eNB102-2 from the LTE network 706 may provide its PRS configuration to gNB102-1 of the 5G NR network 702.

[0108] In stage 4, the gNB 102-1 may request that the eNB 102-2 adjust the muting pattern of the LTE PRS. For example, the muting pattern of the LTE PRS may be adjusted such that SSB scheduling by the gNB 102-1 is possible in four consecutive OFDM symbols in the NR subframe, which is equal to two consecutive symbols in the LTE subframe. The request to adjust the muting pattern may be due to, for example, LTE PRS density, SSB periodicity, or avoiding excessive overhead on the NR data to transmit the SSB. In addition, the muting pattern of the LTE PRS may be adjusted such that, for example, LTE PRS muting may be used to provide NR data to the UE 104 if the UE 104 indicates that it does not support rate matching around the LTE PRS.

[0109] In stage 5, eNB102-2 from the LTE network 706 may provide its PRS configuration to gNB102-1 of the 5G NR network 702, including any adjustments to the LTE PRS muting pattern.

[0110] In stage 6, the server 703 may provide the UE 104 with DSS configuration information to enable the UE 104 to receive NR control and data signals from the gNB 102-1. For example, the DSS configuration information may include LTE PRS rate-matching information, such as an LTE PRS rate-matching pattern or LTE PRS configuration, such as one or more of a carrier frequency, a carrier bandwidth, a number of consecutive PRS subframes, a PRS periodicity, a PRS configuration index, a muting pattern, or a combination thereof, with which the UE 104 may determine an LTE PRS rate-matching pattern. The LTE PRS rate-matching information may include muting information. In addition, the DSS configuration information may include, for example, LTE CRS rate-matching information.

[0111] In stage 7, the UE 104 receives NR control and data signals from the gNB 102-1. The NR control and data signals may be, for example, at least one of a physical downlink shared channel (PDSCH) transmission and a physical downlink common channel (PDCCH) transmission, or a combination thereof. In some implementations, the data and control transmissions may be scheduled for when the LTE PRS is muted.

[0112] In step 8, while the UE 104 is receiving the NR control and data signals in step 7, the eNB 102-2 transmits LTE PRSs to the UE 704. The LTE PRSs are in the same spectrum as the NR control and data signals transmitted by the gNB 102-1 and will therefore be received by the UE 104. Some of the LTE PRSs transmitted by the eNB 102-2 may be muted.

[0113] In stage 9, the UE 104 decodes and processes the NR control and data signals received in stage 7, e.g., by rate matching around the LTE PRS transmitted in stage 8. In some implementations, the LTE PRS may be muted in stage 7 to allow reception of certain signals, such as SSB, or to allow reception of NR control and data signals if the UE 104 is unable to LTE PRS rate match. If the UE 104 is unable to LTE PRS rate match, the UE 104 may still receive NR control and data signals, e.g., during MBSFN frames.

[0114] In step 10, the UE 704 may perform positioning measurements using the LTE PRS received in step 8.

[0115] FIG. 8 illustrates a flowchart of an example procedure 800 for wireless communications performed by a user equipment (UE), such as a UE 104, connected to a new radio (NR) network, such as a 5G NR network 190, for example, to receive NR data and control signals while LTE PRS is transmitted on one or more frequency bands using DSS.

[0116] As shown, in block 802, the UE receives LTE PRS rate matching information from an entity in the NR network for LTE positioning reference signals (PRS) transmitted by base stations in the LTE network, such as long-term evolution (LTE) 160, in one or more frequency bands shared by the NR network using dynamic spectrum sharing (DSS), e.g., as discussed in step 6 of FIG. 7. In block 804, the UE receives NR data and control signals transmitted by base stations in the NR network, as well as LTE PRS transmitted by base stations in the LTE network on one or more frequency bands, e.g., as discussed in steps 7 and 8 of FIG. 7. In block 806, the UE decodes and processes NR data and control signals from base stations in the NR network by rate matching around the LTE PRS in accordance with the LTE PRS rate matching information, e.g., as discussed in step 9 of FIG. 7.

[0117] In one implementation, NR data and control signals transmitted by base stations in an NR network include at least one of a physical downlink shared channel (PDSCH) transmission, a physical downlink common channel (PDCCH) transmission, a synchronization signal block (SSB) transmission, or a combination thereof, as discussed in step 7 of FIG. 7.

[0118] In one implementation, the LTE PRS rate-matching information may be an LTE PRS rate-matching pattern, e.g., as discussed in step 6 of Figure 7. In another implementation, the LTE PRS rate-matching information may be LTE PRS configuration data, e.g., as discussed in step 6 of Figure 7. For example, the LTE PRS configuration data includes one or more of a carrier frequency, a carrier bandwidth, a number of consecutive PRS subframes, a PRS periodicity, a PRS configuration index, a muting pattern, or a combination thereof, as discussed in step 6 of Figure 7.

[0119] In one implementation, the UE may further send an indication of the capability of rate matching around the LTE PRS in the DSS to an entity in the NR network prior to receiving the LTE PRS rate matching information, e.g., as discussed in stage 2 of FIG. 7.

[0120] In one implementation, the UE may further receive a muting pattern for the LTE PRS in the LTE PRS rate matching information, e.g., as discussed in step 6 of FIG. 7, where the muting pattern is based at least in part on a synchronization signal block (SSB) periodicity from the NR network. The UE may receive an SSB transmission from a base station in the NR network while the LTE PRS transmitted by the base station in the LTE network is muted, e.g., as discussed in step 9 of FIG. 7. For example, the LTE PRS may be muted for at least two symbols in a physical resource block (PRB) transmitted by a base station in the LTE network to leave at least four consecutive symbols available for SSB transmission in the PRB transmitted by the base station in the NR network, e.g., as discussed with reference to FIG. 6.

[0121] FIG. 9 illustrates a flowchart of an example procedure 900 for wireless communications performed by a user equipment (UE), such as a UE 104, connected to a new radio (NR) network, such as a 5G NR network 190, for example, to receive NR data and control signals while LTE PRS is transmitted on one or more frequency bands using DSS.

[0122] As shown, in block 902, the UE transmits an indication to an entity in a long-term evolution (LTE) network that the UE does not support rate matching around an LTE positioning reference signal (PRS) transmitted by a base station in the LTE network in one or more frequency bands shared by the NR network using dynamic spectrum sharing (DSS), e.g., as discussed in step 2 of FIG. 7. In block 904, the UE receives a muting pattern for the LTE PRS, e.g., as discussed in step 6 of FIG. 7. In block 906, the UE may receive NR data and control signals transmitted by a base station in the NR network while the LTE PRS transmitted by the base station in the LTE network is muted, e.g., as discussed in step 9 of FIG. 7.

[0123] In one implementation, NR data and control signals transmitted by base stations in an NR network include at least one of a physical downlink shared channel (PDSCH) transmission, a physical downlink common channel (PDCCH) transmission, a synchronization signal block (SSB) transmission, or a combination thereof, as discussed in step 7 of FIG. 7.

[0124] In one implementation, the control information transmitted by the base station in the NR network includes a synchronization signal block (SSB), and the LTE PRS is muted for at least two symbols in a physical resource block (PRB) transmitted by the base station in the LTE network to leave at least four consecutive symbols available for SSB transmission in the PRB transmitted by the base station in the NR network, e.g., as discussed with reference to FIG. 6.

[0125] FIG. 10 illustrates a flowchart of an example procedure 1000 for wireless communications performed by an entity in a 5G NR network, such as a base station 102-1 in a 5G NR network 190, shown in FIGS. 1 and 7, for providing NR data and control signals to a UE while an LTE PRS is transmitted on one or more frequency bands using DSS.

[0126] As shown, in block 1002, an entity obtains from an entity in a LTE network LTE PRS configuration data for a long-term evolution (LTE) positioning reference signal (PRS) transmitted in one or more frequency bands shared by a base station in the NR network using dynamic spectrum sharing (DSS), for example, as discussed in steps 3 and 5 of FIG. 7. In block 1004, the entity transmits LTE PRS rate matching information for the LTE PRS transmitted in one or more frequency bands shared by a base station in the NR network, for example, as discussed in step 6 of FIG. 7, to a user equipment (UE) connected to a base station in the NR network. In block 1006, the entity transmits NR data and control signals to the UE while the LTE PRS is transmitted by a base station in the LTE network on one or more frequency bands, for example, as discussed in steps 7 and 8 of FIG. 7. In block 1008, the UE receives and decodes the NR data and control signals by rate matching around the LTE PRS according to the LTE PRS rate matching information, for example, as discussed in step 9 of FIG. 7.

[0127] In one implementation, NR data and control signals transmitted by base stations in an NR network include at least one of a physical downlink shared channel (PDSCH) transmission and a physical downlink common channel (PDCCH) transmission, or a combination thereof, as discussed in step 7 of FIG.

[0128] In one implementation, the LTE PRS rate-matching information may be an LTE PRS rate-matching pattern, e.g., as discussed in step 6 of Figure 7. In another implementation, the LTE PRS rate-matching information may be LTE PRS configuration data, e.g., as discussed in step 6 of Figure 7. For example, the LTE PRS configuration data includes one or more of a carrier frequency, a carrier bandwidth, a number of consecutive PRS subframes, a PRS periodicity, a PRS configuration index, a muting pattern, or a combination thereof, as discussed in step 6 of Figure 7.

[0129] In one implementation, the entity receives an indication of the capability of rate matching around the LTE PRS in the DSS from the UE prior to receiving the LTE PRS rate matching information, for example as discussed in stage 2 of FIG.

[0130] In one implementation, the entity may modify a muting pattern for an LTE PRS based at least in part on a synchronization signal block (SSB) periodicity from the NR network, e.g., as discussed in step 4 of FIG. 7. The modified muting pattern may be transmitted to the UE, e.g., as discussed in step 6 of FIG. 7. The entity may transmit an SSB transmission to the UE while an LTE PRS transmitted by a base station in the LTE network is muted, e.g., as discussed in steps 7 and 9 of FIG. 7. For example, the LTE PRS is muted for at least two symbols in a physical resource block (PRB) transmitted by a base station in the LTE network to leave at least four consecutive symbols available for SSB transmission in the PRB transmitted by the base station in the NR network, e.g., as discussed with reference to FIG. 6. In one implementation, the entity may modify the muting pattern for the LTE PRS based at least in part on the SSB periodicity from the NR network, e.g., by sending the SSB periodicity to a base station in the LTE network, as discussed in step 4 of FIG. 7, and receiving a modified muting pattern from a base station in the LTE network, as discussed in step 5 of FIG. 7.

[0131] FIG. 11 shows a flowchart of an example procedure 1100 for wireless communication performed by an entity in a 5G New Radio (NR) network, such as a base station 102-1 in the NR network 190, as shown in FIGS. 1 and 7.

[0132] As shown, in block 1102, the entity receives an indication from a user equipment (UE) connected to an NR network that the UE does not support rate matching around a long-term evolution (LTE) positioning reference signal (PRS) transmitted in one or more frequency bands shared by the NR network using dynamic spectrum sharing (DSS), e.g., as discussed in step 2 of FIG. 7. In block 1104, the entity schedules data and control transmissions from a base station in the NR network for when the LTE PRS is muted, e.g., as discussed in step 7 of FIG. 7. In block 1106, a muting pattern for the LTE PRS may be sent to the UE, e.g., as discussed in step 6 of FIG. 7. In block 1108, the entity may send NR data and control signals to the UE while the LTE PRS transmitted by the base station in the LTE network is muted, e.g., as discussed in steps 7 and 9 of FIG. 7.

[0133] In one implementation, NR data and control signals transmitted by base stations in an NR network include at least one of a physical downlink shared channel (PDSCH) transmission, a physical downlink common channel (PDCCH) transmission, a synchronization signal block (SSB) transmission, or a combination thereof, as discussed in step 7 of FIG. 7.

[0134] In one implementation, the control information transmitted by the base station in the NR network includes a synchronization signal block (SSB), and the LTE PRS is muted for at least two symbols in a physical resource block (PRB) transmitted by the base station in the LTE network to leave at least four consecutive symbols available for SSB transmission in the PRB transmitted by the base station in the NR network, e.g., as discussed with reference to FIG. 6.

[0135] FIG. 12 illustrates an example of a hardware implementation of a UE 1200, such as a user equipment (UE) 104. The UE 1200 may be capable of connecting to a 5G NR wireless network, such as a 5G NR network 190, that shares one or more frequency bands with an LTE network, e.g., an LTE network 160, using DSS. The UE 1200 may include, for example, one or more processors 1202, memory 1204, and an external interface, such as a wireless transceiver 1210 (e.g., a wireless network interface), which may be operatively coupled to a non-transitory computer-readable medium 1220 and one or more connections 1206 (e.g., a bus, line, fiber, link, etc.) to the memory 1204. The UE 1200 may further include additional items, not shown, such as a user interface, which may include a display, a keypad, or other input device, such as a virtual keypad on a display, or a satellite positioning system receiver, through which a user may interface with the UE. In some example implementations, all or a portion of the UE 1200 may be in the form of a chipset, or the like. The wireless transceiver 1210 may include, for example, a transmitter 1212 enabled to transmit one or more signals over one or more types of wireless communication networks and a receiver 1214 for receiving one or more signals transmitted over the one or more types of wireless communication networks.

[0136] In some embodiments, the UE 1200 may include an antenna 1211, which may be an internal or external antenna. The UE antenna 1211 may be used to transmit and / or receive signals processed by the wireless transceiver 1210. In some embodiments, the UE antenna 1211 may be coupled to the wireless transceiver 1210. The wireless transceiver 1210 may be capable of transmitting and receiving both WWAN and WLAN signals, or one or more additional transceivers may be included. In some embodiments, measurements of signals received (transmitted) by the UE 1200 may be performed at the connection point of the UE antenna 1211 and the wireless transceiver 1210. For example, the measurement reference points for received (transmitted) RF signal measurements may be the input (output) terminal of the receiver 1214 (transmitter 1212) and the output (input) terminal of the UE antenna 1211. In a UE 1200 with multiple UE antennas 1211 or antenna arrays, the antenna connector may be considered to be a virtual point representing the aggregate output (input) of the multiple UE antennas. In some embodiments, the UE 1200 may measure received signals including signal strength and TOA measurements, and the raw measurements may be processed by one or more processors 1202.

[0137] The one or more processors 1202 may be implemented using a combination of hardware, firmware, and software. For example, the one or more processors 1202 may be configured to perform functions discussed herein by implementing one or more instructions or program code 1208 on a non-transitory computer-readable medium, such as the medium 1220 and / or the memory 1204. In some embodiments, the one or more processors 1202 may represent one or more circuits configurable to perform at least a portion of a data signal computation procedure or process associated with the operation of the UE 1200.

[0138] The medium 1220 and / or memory 1204 may store instructions or program code 1208, including executable code or software instructions that, when executed by the one or more processors 1202, cause the one or more processors 1202 to operate as a special purpose computer programmed to perform the techniques disclosed herein. As shown in the UE 1200, the medium 1220 and / or memory 1204 may include one or more components or modules that may be implemented by the one or more processors 1202 to perform the methods disclosed herein. Although the components or modules are shown as software in the medium 1220 that is executable by the one or more processors 1202, it should be understood that the components or modules may be stored in the memory 1204 or may be dedicated hardware that is either within the one or more processors 1202 or external to the processor.

[0139] A number of software modules and data tables may be present within the medium 1220 and / or memory 1204 and utilized by the one or more processors 1202 to manage both the communications and functionality described herein. It should be understood that the organization of the contents of the medium 1220 and / or memory 1204 as shown in the UE 1200 is merely exemplary, such that the functionality of the modules and / or data structures may be combined, separated, and / or structured in various ways depending on the implementation of the UE 1200.

[0140] The medium 1220 and / or the memory 1204 may include a capability indication module 1222 that, when implemented by the one or more processors 1202, configures the one or more processors 1202 to transmit, via the wireless transceiver 1210, an indication of whether the UE is capable of rate matching around the LTE PRS in the DSS to an entity in the NR network. The indication of whether the UE is capable of rate matching around the LTE PRS may be in response to a request for an indication received from an entity in the NR network.

[0141] The medium 1220 and / or the memory 1204 may include an LTE PRS rate matching information module 1224 that, when implemented by the one or more processors 1202, configures the one or more processors to receive, via the wireless transceiver 1210, LTE PRS rate matching information from an entity in the NR network for LTE PRSs transmitted by base stations in LTE in a shared frequency band using DSS. For example, the LTE PRS rate matching information may be an LTE PRS rate matching pattern. In another example, the LTE PRS rate matching information may be LTE PRS configuration data, such as one or more of a carrier frequency, a carrier bandwidth, a number of consecutive PRS subframes, a PRS periodicity, a PRS configuration index, a muting pattern, or a combination thereof.

[0142] The medium 1220 and / or the memory 1204 may include an LTE PRS muting information module 1226 that, when implemented by the one or more processors 1202, configures the one or more processors to receive, via the wireless transceiver 1210, from an entity in the NR network, an LTE PRS muting pattern for an LTE PRS transmitted by a base station in LTE in the shared frequency band using DSS.

[0143] The medium 1220 and / or the memory 1204 may include an LTE PRS rate matching pattern module 1228 that, when implemented by the one or more processors 1202, configures the one or more processors 1202 to determine an LTE PRS rate matching pattern for rate matching around an LTE PRS. The LTE PRS rate matching pattern may be obtained based on LTE PRS rate matching information received from an entity in the 5G NR network. For example, the LTE PRS rate matching may be an LTE PRS rate matching pattern received from an entity in the 5G NR network, or may be generated based on received LTE PRS configuration data, including one or more of a carrier frequency, a carrier bandwidth, a number of consecutive PRS subframes, a PRS periodicity, a PRS configuration index, a muting pattern, or a combination thereof.
