[0003] background

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, and the like. These systems may be able to support 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) systems, advanced LTE (LTE-A) systems, or LTE-A Pro systems), and fifth generation (5G) systems, which may be referred to as new radio (NR) systems. These systems may employ various 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 of which simultaneously supports communication with multiple communication devices, which may be further referred to as user equipment (UE).

[0005] In some wireless communication systems, a positioning engine (e.g., a location server) or a UE may use, for example, positioning measurements obtained from base stations in a wireless network to which the UE is connected to determine the location or position of a supported UE. This information may be associated with UE-based positioning techniques or UE-assisted positioning techniques. These methods may support various positioning services (e.g., navigation systems, emergency communications) and supplement one or more additional positioning systems (such as Global Positioning System (GPS) technology) supported by wireless communication devices.

[0041] Detailed description

[0042] The detailed description set forth below in conjunction with the accompanying drawings is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. This detailed description includes specific details to provide 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.

[0043] The techniques described herein can be used in 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 can implement radio technologies such as Universal Terrestrial Radio Access (UTRA) and cdma2000. UTRA includes Wideband CDMA (WCDMA) and other variants of CDMA. cdma2000 covers the IS-2000, IS-95, and IS-856 standards. A TDMA network can implement radio technologies such as Global System for Mobile Communications (GSM). An OFDMA network can 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-OFDM, and the like. UTRA and E-UTRA are part of the Universal Mobile Telecommunications System (UMTS). 3GPP Long Term Evolution (LTE) and Advanced LTE (LTE-A) are new versions of UMTS that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A, and GSM are described in documents from an organization called the "3rd Generation Partnership Project" (3GPP). CDMA2000 and UMB are described in documents from an organization called the "3rd Generation Partnership Project 2" (3GPP2). The techniques described herein can 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., 5th Generation (5G) Radio (NR) networks operating in the mmWave band).

[0044] Several aspects of telecommunications systems will now be presented with reference to various devices and methods. These devices and methods are described in the following detailed description and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively, "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 specific application and the design constraints imposed on the overall system.

[0045] As an example, an element, or any part of an element, or any combination of elements can be implemented as a "processing system" comprising one or more processors. Examples of processors include: a microprocessor, a microcontroller, a graphics processing unit (GPU), a central processing unit (CPU), an application processor, a digital signal processor (DSP), a reduced instruction set computing (RISC) processor, a system on a chip (SoC), a baseband processor, a field programmable gate array (FPGA), a programmable logic device (PLD), a state machine, a gating logic, a discrete hardware circuit, and other suitable hardware configured to perform the various functionalities described throughout this disclosure. One or more processors in a processing system can execute software. Software should be broadly interpreted to mean instructions, instruction sets, codes, code segments, program codes, programs, subroutines, software components, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, etc., whether it is described in software, firmware, middleware, microcode, hardware description language, or other terms.

[0046] Accordingly, in one or more example embodiments, the functions described may be implemented in hardware, software, or any combination thereof. If implemented in software, each function may be stored or encoded as one or more instructions or codes on a computer-readable medium. Computer-readable media include computer storage media. Storage media may be any available medium that can be accessed by a computer. By way of example and not limitation, such computer-readable media may include random access memory (RAM), read-only memory (ROM), electrically erasable programmable ROM (EEPROM), optical disk storage, magnetic disk storage, other magnetic storage devices, a combination of the aforementioned types of computer-readable media, or any other medium that can be used to store instructions or data structures in the form of computer-executable code that can be accessed by a computer.

[0047] To meet the growing demand for expanded connectivity, wireless communication technology, or RAT, is evolving from LTE (sometimes referred to as 4G) to next-generation NR (sometimes referred to as 5G NR). For example, 5G NR can offer lower latency and higher bandwidth or throughput than LTE. 5G NR is beginning to be deployed in markets where LTE is already established. 5G NR deployment is considered using both repurposed and new frequency bands.

[0048] 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, for example based on the distribution of LTE and 5G NR traffic, and is sometimes referred to as dynamic spectrum sharing (DSS). DSS allows 5G NR to be efficiently deployed and coexist with 4G LTE in the same frequency band. 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.

[0049] The use of DSS provides several benefits. For example, resource reuse in the time domain 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 use of inter-radio access technology (IRAT) for handover to LTE. In addition, LTE networks generally have excess capacity, and therefore the impact of DSS on LTE can be minimized. In addition, without LTE spectrum refarming, there is a lack of low-band frequencies for 5G NR, and 5G NR coverage is limited in high-band frequencies.

[0050] Current implementations of DSS effectively handle regularly scheduled signal types, such as cell-specific reference signals (CRS) in LTE and the physical downlink shared channel (PDSCH) in 5G NR. However, one type of LTE signal that is not regularly scheduled but is specifically configured on demand is the positioning reference signal (PRS). Because PRS is configured on demand and is not a regularly scheduled signal type, current LTE-NR DSS technology cannot accommodate PRS.

[0051] This document describes various implementations for permitting continued use of PRS for positioning in LTE, e.g., on shared bands where LTE and 5G NR are deployed using DSS.

[0052] Figure 1 A diagram shows an example of a wireless communication system 100 including multiple separate wireless networks. The wireless communication system (also known 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 (a high-power cellular base station) and / or a small cell (a low-power cellular base station). A macro cell includes a base station. Small cells include femto cells, pico cells, and micro cells.

[0053] Base stations 102 configured for 4G LTE (collectively referred to as the Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) can interface with the EPC 160 via a backhaul link 132 (e.g., an S1 interface). Base stations 102 configured for 5G NR (collectively referred to as the Next Generation RAN (NG-RAN)) can interface with the 5GC 190 via a backhaul link 184 (e.g., an N2, N3, or other interface). Among other functions, base stations 102 can perform one or more of the following: delivery of user data, radio channel encryption and decryption, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity), inter-cell interference coordination, connection establishment and release, load balancing, distribution of 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 within the same wireless network can communicate with each other directly or indirectly (e.g., via a core network or an intermediate base station) over a backhaul link 134 (e.g., an X2, Xn, or other interface) or directly or indirectly (e.g., via EPC 160 or 5GC 190). Backhaul link 134 can be wired or wireless.

[0054] Base stations 102 can communicate wirelessly with UEs 104. Each base station 102 can provide communication coverage for a respective geographic coverage area 110. There may be overlapping geographic coverage areas 110. For example, a small cell 102′ can have a coverage area 110′ that overlaps with the coverage area 110 of one or more macro base stations 102. A network that includes both small cells and macro cells can be referred to as a heterogeneous network. A heterogeneous network can also include a home evolved Node B (eNB) (HeNB), which can provide service to a restricted group known as a closed subscriber group (CSG). The communication link 120 between the base station 102 and the UE 104 can include uplink (UL) (also known as reverse link) transmissions from the UE 104 to the base station 102 and / or downlink (DL) (also known as forward link) transmissions from the base station 102 to the UE 104. The communication link 120 can use multiple-input multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming, and / or transmit diversity. These communication links can be over one or more carriers. Base station 102 / UE 104 may use spectrum with a bandwidth of up to Y MHz (e.g., 5, 10, 15, 20, 100, 400 MHz, etc.) for each carrier allocated in the carrier aggregation for a total of up to Yx MHz (x component carriers) for transmission in each direction. These carriers may or may not be contiguous to each other. The allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated to DL compared to UL). 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 carriers may be referred to as secondary cells (SCells).

[0055] The term "cell" refers to a logical communication entity used to communicate with a base station (e.g., on a carrier) and can be associated with an identifier to distinguish between adjacent cells operating via the same or different carriers (e.g., physical cell identifier (PCID), virtual cell identifier (VCID)). In some examples, a carrier can support multiple cells, and different cells can be configured according to different protocol types that can provide access to different types of devices (e.g., machine type communication (MTC), narrowband Internet of Things (NB-IoT), enhanced mobile broadband (eMBB), or other protocol types). In some examples, the term "cell" can refer to a portion of the geographic coverage area 110 (e.g., a sector) on which the logical entity operates.

[0056] Some 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). D2D communication may be accomplished through various wireless D2D communication systems, such as, for example, FlashLinQ, WiMedia, Bluetooth, ZigBee, Wi-Fi based on the IEEE 802.11 standard, LTE, or NR.

[0057] The wireless communication system may further include a Wi-Fi access point (AP) 150 that communicates with a Wi-Fi station (STA) 152 in the 5 GHz unlicensed spectrum via a communication link 154. When communicating in the unlicensed spectrum, the STA 152 / AP 150 may perform a clear channel assessment (CCA) prior to communication to determine whether the channel is available.

[0058] Small cell 102′ may operate in licensed and / or unlicensed spectrum. When operating in unlicensed spectrum, small cell 102′ may employ NR and use the same 5 GHz unlicensed spectrum used by Wi-Fi AP 150. Small cell 102′ employing NR in the unlicensed spectrum may improve access network coverage and / or increase access network capacity.

[0059] Whether a small cell 102′ or a large cell (e.g., a macro base station), base station 102 may include an eNB, a gNode B (gNB), or another type of base station. Some base stations, such as gNB 180, may operate in the traditional sub-6 GHz spectrum, millimeter wave (mmW) frequencies, and / or near-mmW frequencies to communicate with UE 104. When gNB 180 operates in mmW or near-mmW frequencies, gNB 180 may be referred to as a mmW or mmW base station. Extremely high frequency (EHF) is a portion of the RF spectrum in the electromagnetic spectrum. EHF has a range of 20 GHz to 200 GHz and a wavelength between 1 mm and 10 mm. Radio waves in this band may be referred to as millimeter waves. Near-mmW extends down to 2 GHz frequencies with a wavelength of 100 mm. Super high frequency (SHF) bands extend between 2 GHz and 20 GHz and are also referred to as centimeter waves. Communications using mmW / near-mmW radio frequency bands (e.g., 2 GHz–200 GHz) have extremely high path loss and short range. The mmW base station 180 may utilize beamforming 182 with the UE 104 to compensate for the extremely high path loss and short range.

[0060] Base station 180 may transmit beamformed signals in one or more transmit directions 182′ to UE 104. UE 104 may receive beamformed signals from base station 180 in one or more receive directions 182″. UE 104 may also transmit beamformed signals to base station 180 in one or more transmit directions. Base station 180 may receive beamformed signals from UE 104 in one or more receive directions. Base station 180 / UE 104 may perform beam training to determine the best receive direction and transmit direction for each of base station 180 / UE 104. The transmit direction and receive direction of base station 180 may be the same or different. The transmit direction and receive direction of UE 104 may be the same or different.

[0061] The core network 160 / 190 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, positioning, and other access, routing, or mobility functions.

[0062] By way of example, EPC 160 may include 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. MME 162 may be in communication with a Home Subscriber Server (HSS) 174. MME 162 is a control node that handles signaling between UE 104 and EPC 160. Generally speaking, MME 162 provides bearer and connection management. E-SMLC 164 may support UE location determination, for example, using a 3GPP Control Panel (CP) location solution. All user Internet Protocol (IP) packets pass through Serving Gateway 166, which itself is connected to PDN Gateway 172. PDN Gateway 172 provides UE IP address allocation and other functions. PDN Gateway 172 is connected to IP Services 176. IP services 176 may include the Internet, an intranet, an IP Multimedia Subsystem (IMS), a PS streaming service, and / or other IP services. GMLC 168 may provide access to the UE's location on behalf of an external client 169 (e.g., which may be internal or external to IP services 176). 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 subscription information stored in H-SLP 170.

[0063] As an example, 5GC 190 may include 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. AMF 192 may be in communication with a unified data management (UDM) 197. AMF 192 is a control node that handles signaling between UE 104 and 5GC 190 and, to implement positioning functionality, may communicate with LMF 196, which supports UE location determination. In some implementations, LMF 196 may be co-located with base station 105 in the NR-RAN and may be referred to as a location management component (LMC). GMLC 193 may be used to allow external clients 199, either external or internal to IP services 198, to receive location information about the UE. All user Internet Protocol (IP) packets may pass through UPF 195. UPF 195 provides UE IP address allocation, among other functions. UPF 195 connects to IP services 198. H-SLP 191 may likewise connect to IP services 198. IP services 198 may include the Internet, an intranet, an IP Multimedia Subsystem (IMS), a PS streaming service, and / or other IP services.

[0064] A base station may also be referred to as a gNB, a NodeB, an evolved NodeB (eNB), an access point, a base transceiver station, a radio base station, a radio transceiver, a transceiver function, a basic service set (BSS), an extended service set (ESS), a transmit reception point (TRP), or some other suitable terminology. Base station 102 provides an access point for UE 104 to EPC 160 or 5GC 190. Examples of 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., an MP3 player), a camera, a game console, a tablet device, a smart device, a wearable device, a vehicle, an electric meter, a gas pump, a large or small kitchen appliance, a healthcare device, an implant, a sensor / actuator, a display, or any other similarly functional device. Some UEs 104 may be referred to as IoT devices (e.g., a parking meter, a gas pump, an oven, a vehicle, a heart monitor, etc.). Some UEs 104 may be referred to as Industrial Internet of Things (IIoT) devices, such as sensors, meters, and other devices that are networked together in industrial applications. A UE 104 may also be referred to as a station, a mobile station, a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communication device, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, a user agent, a mobile client, a client, or some other suitable terminology.

[0065] UE 104 may enter a state of connectivity with a wireless communication network, which may include base station 102 for location determination. In one example, UE 104 may communicate with a cellular wireless network by transmitting wireless signals to or receiving wireless signals from a cellular base station. In another example, UE 104 may communicate with a base station of a local area network (LAN), such as a Wi-Fi access point or other wireless network.

[0066] In certain implementations, 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 Global Navigation Satellite System (GNSS) such as GPS, GLONASS, Galileo, or BeiDou, and / or may include measurements of signals received from ground-based base stations fixed at known locations (e.g., Figure 1 102). UE 104 or a location server (e.g., E-SMLC 164, H-SLP 170, or LMF 196) to which UE 104 may send measurements may then obtain a position estimate for UE 104 based on these position-related measurements using any of several positioning methods, such as, for example, GNSS, Assisted-GNSS (A-GNSS), Advanced Forward Link Trilateration (AFLT), Observed Time Difference of Arrival (OTDOA), WLAN (also known as WiFi) positioning, Angle of Departure (AOD), Angle of Arrival (AOA), multi-cell round-trip time (multi-RTT), or Enhanced Cell ID (ECID), or a combination thereof. In some of these techniques (e.g., A-GNSS, AFLT, and OTDOA), pseudoranges or timing differences relative to three or four ground base stations 102 fixed at known locations can be measured at the UE 104 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.

[0067] In some examples, the base station 102 can transmit a downlink positioning signal, such as a PRS or a tracking reference signal. The positioning signal transmission can be configured for a specific UE 104 to measure one or more parameters and use them as part of a UE-based positioning technique or report them as part of a UE-assisted positioning technique. Similarly, the UE 104 can transmit a positioning signal, such as an uplink PRS or a sounding reference signal, and the base station 102 can measure one or more parameters to be used as part of a UE-based positioning technique or as part of a UE-assisted positioning technique. PRS transmission and reporting parameter feedback can support various positioning services (e.g., navigation systems and emergency communications). In some examples, the reporting parameters supplement one or more additional positioning systems supported by the UE 104, such as global positioning system (GPS) technology.

[0068] The base station 102 may configure PRS transmission on one or more PRS resources of a channel. Depending on the configured port number, the PRS resource may span resource elements of multiple physical resource blocks (PRBs) within one or more OFDM symbols of a time slot. For example, a PRS resource may span one symbol of a time 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 a time slot. In other examples, the PRS transmission may be mapped to interspersed OFDM symbols of a time slot. Additionally, the PRS transmission may support frequency hopping within a PRB of a channel.

[0069] Aspects of the wireless communication system 100 may include UE position determination using PRS transmissions by a base station 102 or Sounding Reference Signal (SRS) transmissions by a UE 104. For downlink-based UE position 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 providing PRS Assistance Data (AD) to the UE 104. In UE-assisted positioning, the location server may receive measurement reports from the UE 104 indicating position measurements for one or more base stations 102, which the location server may use to determine a position estimate for the UE 104, for example, using OTDOA or other desired techniques.

[0070] As discussed above, DSS can be used to flexibly allocate existing spectrum across frequency bands by dynamically switching between 4G LTE and 5G NR coverage based on, for example, traffic demand.

[0071] Figure 2 A block diagram shows a design 200 of a base station 102 and a UE 104, which may be Figure 1One for each base station and one for each UE in the base station 102. 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.

[0072] At base station 102, transmit processor 220 may receive data for one or more UEs from 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 for all UEs. Transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, upper layer signaling, etc.), and provide overhead symbols and control symbols. Transmit processor 220 may also generate reference symbols for reference signals (e.g., a cell-specific reference signal (CRS)) and synchronization signals (e.g., a primary synchronization signal (PSS) and a secondary synchronization signal (SSS)). A transmit (TX) multiple-input, multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, as 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 frequency 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 greater detail below, position coding may be utilized to generate synchronization signals to convey additional information.

[0073] At UE 104, antennas 252a through 252r can receive downlink signals from base station 102 and / or other base stations and can provide received signals to demodulators (DEMODs) 254a through 254r, respectively. Each demodulator 254 can condition (e.g., filter, amplify, downconvert, and digitize) the received signals to obtain input samples. Each demodulator 254 can further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. A MIMO detector 256 can obtain received symbols from all R demodulators 254a through 254r, perform MIMO detection on the received symbols where applicable, and provide detected symbols. A receive processor 258 can process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 104 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The channel processor may determine reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), channel quality indicator (CQI), etc. In some aspects, one or more components of the UE 104 may be included in a housing.

[0074] 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 including 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 through 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 antenna 234, processed by the demodulator 232, detected by the 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 decoded data to a data sink 239 and decoded control information to a controller / processor 240. The base station 102 may include a communication unit 244 and 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.

[0075] The controller / processor 240 of the base station 102, the controller / processor 280 of the UE 104, and / or Figure 2Any other component(s) of the base station 102 may perform one or more techniques associated with receiving NR data and control signals by the UE 104 while the LTE PRS is being transmitted on the shared spectrum using the 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 Figure 2 Any other component(s) may perform or direct e.g. Figure 8-11 The operations of processes 800, 900, 1000, and 1100 and / or other processes as described herein may be performed. Memories 242 and 282 may store data and program codes for base station 102 and UE 104, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions for wireless communication. For example, the one or more instructions, when executed by one or more processors of base station 102 and / or UE 104, may perform or direct, for example, Figure 8-11 The scheduler 246 may schedule UEs for NR data and control transmission on the downlink and / or uplink based on the LTE PRS rate matching pattern and / or the LTE PRS muting pattern.

[0076] As indicated above, Figure 2 are provided as examples. Other examples may differ from those described in Figure 2 Examples described.

[0077] 5G NR networks are beginning to be deployed in areas where LTE networks are already established. Instead of acquiring new spectrum or refarming already used spectrum, 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 the LTE network, but with minimal impact on the performance of the LTE network.

[0078] For example, a Multimedia Broadcast Signal Frequency Network (MBSFN) subframe may be used to provide the gaps necessary for transmission of synchronization signal blocks (SSBs) used by the NR UE 104 to maintain time and frequency synchronization with the 5G NR network 190.

[0079] Figure 3A For example, an MBSFN subframe 300 with an NR SSB 302 shared by an LTE network 160 and a 5G NR network 190 is illustrated. However, the use of the MBSFN subframe is restricted. For example, to limit the impact on LTE performance, the MBSFN subframe may be limited to a single subframe.

[0080] Accordingly, the DSS additionally enables subframes dedicated to LTE and not configured for MBSFN to be used for 5G NR data and control messages. Standard LTE subframes include cell-specific reference signals (CRS) mapped to certain resource elements. UEs connected to LTE use this CRS for channel estimation and to maintain time and frequency synchronization. Even in subframes where LTE data is not scheduled, the LTE CRS will still be present. To enable 5G NR to use subframes with LTE CRS, rate matching around the LTE CRS is used.

[0081] Figure 3B For example, a non-MBSFN subframe 350 is illustrated that includes an LTE CRS and NR data (PDSCH) that is rate-matched around the LTE CRS. LTE CRS is a periodically transmitted signal, and thus only a few factors influence the rate matching algorithm. For example, the offset for subcarrier alignment and the number of antenna ports must be known. In addition, because CRS is cell-specific, another factor used to rate-match the LTE CRS is V. shift , which represents the impact of the physical cell identity (PCI) (v shift =PCI mod 6), which defines the starting point (subcarrier) for mapping the LTE sequence used to generate the CRS. These factors can be communicated to the NR UE 104, for example, using a radio resource control (RRC) connection. Because these factors do not change over time as long as the NR UE 104 is connected to the same cell, the NR UE 104 can rate-match around the LTE CRS rate in each subframe.

[0082] MBSFN subframes 300 and non-MBSFN subframes 350 illustrate specific subframes that can 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 where important LTE signal components (e.g., LTE CRS) are still being transmitted. DSS additionally enables LTE and NR to share subframes in which both control information (PDCCH and CORESET) and data (PDSCH) are transmitted. Dynamic sharing of subframes is made possible, for example, by coordination of scheduling resources in the frequency and time domains at the media access control layer in base stations of both the LTE network and the 5G NR network 190.

[0083] Figure 3CFor example, a wireless communication system 370 is illustrated that includes 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 gNB 374 share the same spectrum using the DSS. As illustrated by arrow 376, the NR UE 104 connects to the gNB 374 to wirelessly receive NR control and data signals. Because the gNB 374 and eNB 372 share spectrum via the DSS, the eNB 372 transmits a signal 378 on the 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 eNB 372, operating using independent schedulers, can coordinate via an Xn interface 380 in a dual connectivity manner. For example, the gNB 374 and eNB 372 may coordinate using a bitmap that provides an indication of data traffic resources, such as which PRBs are reserved for LTE and which are not.

[0084] As discussed above, because LTE CRS is a regularly transmitted signal that does not change, it can be easily handled using DSS. However, LTE PRS signals are not transmitted regularly but are configured on demand. Accordingly, current DSS technology cannot accommodate LTE PRS.

[0085] Figure 4 The structure of an exemplary subframe sequence 400 with positioning reference signal (PRS) positioning opportunities according to aspects of the present disclosure is shown. The subframe sequence 400 can be suitable for broadcasting PRS signals from a base station (e.g., any base station described herein) or other network node. The subframe sequence 400 can be used in LTE systems, and the same or similar subframe sequences can be used in other communication technologies / protocols (such as 5G and NR). Figure 4 In FIG, time is represented horizontally (e.g., on the X-axis), where time increases from left to right, and frequency is represented vertically (e.g., on the Y-axis), where frequency increases (or decreases) from bottom to top. Figure 4 As shown in , downlink and uplink radio frames 410 may each have a duration of 10 milliseconds (ms). For downlink frequency division duplex (FDD) mode, in the illustrated example, the radio frame 410 is organized into ten subframes 412, each of which has a duration of 1 ms. Each subframe 412 includes two time slots 414, each of which has a duration of, for example, 0.5 ms.

[0086] In the frequency domain, the available bandwidth can be divided into evenly spaced orthogonal subcarriers 416 (also referred to as "tones" or "bins"). For example, for a normal length cyclic prefix (CP) using, for example, 15 kHz spacing, the subcarriers 416 can be grouped into groups of twelve (12) subcarriers. A resource (represented as a block of subframes 412) that is one OFDM symbol long in the time domain and one subcarrier in the frequency domain 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 can be written as For a given channel bandwidth, the number of available resource blocks on each channel 422 (which is also referred to as a transmission bandwidth configuration 422) is indicated as For example, for the 2 MHz channel bandwidth in the above example, the number of available resource blocks on each channel 422 is given by Note that the frequency components of a resource block (e.g., 12 subcarriers) are called physical resource blocks (PRBs).

[0087] The base station can Figure 4 , or a similar or identical frame configuration to that shown in , to transmit a radio frame (e.g., radio frame 410) supporting a PRS signal (i.e., downlink (DL) PRS) or other physical layer signaling sequence that can be measured and used for UE (e.g., any UE described herein) position estimation. Other types of wireless nodes in a wireless communication network (e.g., distributed antenna systems (DAS), remote radio heads (RRHs), UEs, APs, etc.) may also be configured to transmit signals to communicate with Figure 4 The PRS signal is configured in a manner similar to (or identical to) that described in .

[0088] The set of resource elements used to transmit a PRS signal is referred to as a "PRS resource." The set of resource elements can span multiple PRBs in the frequency domain and can span N (e.g., one or more) consecutive symbols within a time slot 414 in the time domain. For example, the cross-hatched resource elements in time slot 414 can be examples of two PRS resources. A "PRS resource set" is a set of PRS resources used to transmit a PRS signal, where each PRS resource has a PRS resource identifier (ID). In addition, the PRS resources in a PRS resource set are associated with the same transmit receive point (TRP). The PRS resource ID in a PRS resource set is associated with a single beam transmitted from a single TRP (wherein a TRP can transmit one or more beams). Note that this does not imply whether the TRP and beam transmitting the signal are known to the UE.

[0089] PRS may be transmitted in special positioning subframes grouped into positioning opportunities. A PRS opportunity is an example of a periodically repeating time window (e.g., consecutive time slots) in which PRS is expected to be transmitted. Each periodically repeating time window may include a group of one or more consecutive PRS opportunities. Each PRS opportunity may include a number N PRS The PRS positioning opportunities for the cellular cells supported by the base station can be arranged at intervals (number T PRS milliseconds or subframes). Figure 4 Explains the periodicity of positioning opportunities, where N PRS is equal to 4(418), and T PRS Greater than or equal to 20 (420). In some aspects, T PRS It may be measured in terms of the number of subframes between the start of consecutive positioning opportunities.Multiple PRS opportunities may be associated with the same PRS resource configuration, in which case each such opportunity is referred to as a "PRS resource opportunity" or the like.

[0090] The PRS may be transmitted at constant power. The PRS may also be transmitted at zero power (i.e., muted). Turning off muting of regularly scheduled PRS transmissions may be useful when PRS signals between different cells overlap by appearing 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 constant power). Muting may assist the UE in signal acquisition and time of arrival (TOA) and reference signal time difference (RSTD) measurements of non-muted PRS signals (by avoiding interference from muted PRS signals). Muting may be considered as not transmitting the PRS for a given positioning opportunity for a particular cell. A 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 the bit at position j in the bit string signaled to indicate the muting pattern is set to '0', the UE may infer that the PRS is muted for the jth positioning opportunity.

[0091] To further improve 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 by data transmissions. The frequency shift may be defined as a function of the PRS ID for the cell or other transmission point (TP) (denoted as ) or a function of the physical cell identifier (PCI) if no PRS ID is assigned (denoted by ), which results in an effective frequency reuse factor of six (6).

[0092] Also to improve the audibility of the PRS (e.g., when the PRS bandwidth is limited, such as to have only 6 resource blocks corresponding to a 1.4 MHz bandwidth), the frequency band for consecutive PRS positioning occasions (or consecutive PRS subframes) can be changed in a known and predictable manner via frequency hopping. In addition, a cell supported by a base station can support more than one PRS configuration, where each PRS configuration may include a unique frequency shift (vshift), a unique carrier frequency, a unique bandwidth, a unique code sequence, and / or have a specific number of subframes per positioning occasion (N). PRS ) and specific periodicity (T PRS In some implementations, one or more PRS configurations supported in a cell may be used for directional PRS and may then have additional unique properties (such as a unique transmission direction, a unique horizontal angle range, and / or a unique vertical angle range).

[0093] PRS is not transmitted by all cells and may not be transmitted in every subframe. The PRS configuration as described above, including the PRS transmission / silencing schedule, is signaled or provided to the UE to enable the UE to perform PRS positioning measurements. It is not expected that the UE blindly performs detection of the PRS configuration.

[0094] When a 5G NR network shares one or more frequency bands with an LTE network using DSS, the periodic transmissions of the LTE network (such as CRS) or the periodic transmissions of the 5G NR network (such as PDSCH) are known and can be accommodated by the DSS procedure. For example, the LTE CRS is a cell-specific reference signal that is mapped to resource elements spread across the resource grid in the same pattern in each resource block. Thus, the LTE CRS transmission from a specific cell can be easily identified for each cell and accommodated by the DSS procedure.

[0095] However, unlike LTE CRS, LTE PRS is not transmitted by all cells at all times, and if transmitted by a cell, it is not transmitted in every subframe. PRS transmission is configuration-based, e.g., PRS transmission occurs only in configured cells and only in configured subframes (not all subframes). In addition, the mapping of PRS to resource elements in the resource grid is configured. Accordingly, unlike LTE CRS, LTE PRS is not predictable and periodic, and cannot be accommodated by current DSS technology. 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 PRS, or which subframes or which resource elements within each resource block have been configured for PRS. For example, referring to Figure 3C In the absence of LTE PRS, if UE 104 is receiving a data signal or a control signal from gNB 374 while eNB 372 is transmitting LTE PRS in signal 378, UE 104 will not be able to correctly decode the NR data or control signal in the subframe in which the LTE PRS is present.

[0096] Accordingly, in one implementation, LTE PRS scheduling information is provided to a UE 104 connected to a 5G NR network 190 to enable the UE 104 to rate match NR data around the LTE PRS transmission. For example, a scheduler in a base station 102 of the 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 use the LTE PRS rate matching pattern to rate match NR data. In some implementations, an LTE PRS configuration may be provided to the UE 104, such as one or more of: carrier frequency, carrier bandwidth, number of consecutive PRS subframes, PRS periodicity, PRS configuration index, muting pattern, or a combination thereof, and the UE 104 may determine a rate matching scheme for data transmission from the 5G NR network based on the received LTE PRS configuration and may process data transmission from the 5G network around the LTE PRS transmission. With knowledge of whether a subframe is configured to include an LTE PRS transmission and which subcarriers in the subframe are configured to include a PRS transmission, the UE 104 can puncture the subcarriers at specific times or resource elements with the LTE PRS and receive the remaining resource element subcarriers in the resource block. Thus, the UE 104 can use the PRS rate matching mode and rate-match NR data signals (such as PDSCH and PDCCH) around the LTE PRS transmission. Since the LTE PRS is configured to specific subframes, time slots, and subcarriers, with knowledge of the LTE PRS configuration, the UE 104 can puncture only the affected subframes, time slots, and subcarriers to receive NR data. In addition, the 5G NR network can schedule NR data (such as PDSCH and PDCCH) based on the LTE PRS configuration.

[0097] Figure 5A and 5B For example, an LTE subframe 500 and an NR subframe 550 rate-matched to the LTE subframe 500 are illustrated. The LTE subframe 500 includes an LTE PRS, while 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 can 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 for receiving NR data. In another implementation, the UE 104 can receive an LTE PRS configuration from the 5G NR base station 102, and can determine a corresponding rate matching pattern based on the LTE PRS configuration, and apply the rate matching pattern to the subframe for receiving NR data.

[0098] The UE 104 may provide the 5G RN network with its ability to rate match around LTE PRS transmissions. In some implementations, if the LTE PRS transmission is configured for a band in DSS mode and NR data cannot be scheduled without rate matching, the 5G NR network may deny the UE 104 connection setup or use RRC connection release. For example, scheduling NR data may not be possible due to the 4-symbol SSB constraint or excessive overhead for NR data.

[0099] If the UE 104 does not have the capability to support PRS rate matching, the 5G NR network may limit NR data scheduling to Multicast-Broadcast Single Frequency Network (MBSFN) frames so that NR data is not scheduled in non-MBSFN frames.

[0100] Additionally, the LTE network may adjust the muting pattern of the LTE PRS transmission based on the synchronization signal block (SSB) scheduling of the 5G NR network, which may be shared with the UE 104 for corresponding rate matching in the muted subframes.

[0101] As an example, as illustrated in Table 1, which is a snippet of Abstract Syntax Notation 1 (ASN.1), a UE 104 connected to a 5G NR network may include the capability to rate match LTE PRS transmissions. For example, as illustrated in the table, the UE includes a "rateMatchingLTE-PRS" capability.

[0104] Table 1

[0105] As illustrated in Tables 2 and 3, which are a snippet of ASN.1, the 5G NR network may reuse a rate matching pattern list to provide PRS scheduling information to the UE 104. For example, Table 2 illustrates a PDSCH configuration including "rateMatchPatternToAddModList," while Table 3 illustrates "RateMatchPattern."

[0110]

[0111] Table 3

[0112] As illustrated in Tables 4 and 5, which are fragments of ASN.1, the serving cell may be configured to rate match the NR PDSCH based on the PRS pattern. For example, Table 4 illustrates that the rate matching pattern LTE-CRS may include "RateMatchPatternLTE-PRS", while Table 5 illustrates that the serving cell configuration may include "lte-PRS-ToMatchAround". As can be seen, the rate matching pattern for LTE-PRS includes, for example, the carrier DL frequency ("carrierFreqDL"), the carrier DL bandwidth ("carrierBandwidthDL"), the number of PRSs (i.e., the number of consecutive PRS subframes) ("NPRS"), the PRS period "TPRS", the muting pattern ("MUTINGPATTERN"), and the PRS configuration index.

[0117] Table 5

[0118] In addition to or as an alternative to rate matching NR data around LTE PRS transmissions, the 5G NR base station may transmit NR SSBs (which have a constraint of being transmitted in four consecutive symbols) and / or NR data based on a muting pattern of the LTE PRS, e.g., the NR SSBs and / or data are transmitted in a subframe or slot during which 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 does not have rate matching capabilities. In such cases, the 5G NR network (e.g., a scheduler in the 5G NR base station 102) may schedule NR data transmissions based on the 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 (e.g., via an Xn interface) to adjust its muting pattern so that the NR data can be transmitted.

[0119] Due to the frequency difference, 5G NR network 190 may require at least two consecutive symbols of an LTE subframe in order to transmit, for example, four consecutive OFDM symbols for SSB or NR data. For example, a 5G NR network may require at least two consecutive symbols of the LTE 15 kHz subcarrier spacing (SCS) rate so that a 5G NR 30 kHz SCS can be accommodated in four consecutive OFDM symbols. However, due to the high density of transmitted LTE PRS along with other control signals (e.g., LTE CRS), two consecutive symbols may not be available in an LTE subframe based on the SSB periodicity or may require excessive overhead for NR data. Accordingly, 5G NR network 190 may request LTE network 160 (e.g., via a scheduler in each base station via an Xn interface) to schedule an LTE PRS muting pattern, thereby reserving subframes for 5G NR network 190 to schedule SSBs based thereon. 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, for example, for a subframe or time slot where SSB is scheduled, the LTE PRS is muted to enable SSB scheduling in four consecutive OFDM symbols.

[0120] Figure 6 For example, an LTE subframe 600 including an LTE PRS and NR data (PDSCH) rate-matched around the LTE PRS is illustrated. Figure 6 The LTE PRS is further illustrated as being muted, for example, in symbols 5 and 10. As illustrated, 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 is equivalent to four consecutive OFDM symbols in the NR subframe due to the frequency difference. The LTE subframe 600 further illustrates the NR PDCCH in symbol 6.

[0121] Thus, LTE PRS and NR PDSCH, SSB and PDCCH can coexist using DSS and be supported without significant impact on LTE positioning and at the cost of adding slight overhead to NR PDSCH.

[0122] Figure 7 An example message flow 700 is illustrated illustrating a wireless communication system (such as a reference Figure 1 The wireless communication system 100 discussed includes communications between components of a plurality of wireless networks supporting wireless communications 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 Figure 1As illustrated, 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, a Figure 1 196 is shown in FIG. LTE network 706 may be, for example, LTE network 160 and includes eNB 102-2. gNB 102-1 in 5G NR network 702 and eNB 102-2 in LTE network 706 share one or more frequency bands using DSS. UE 104 is configured to connect to 5G NR network 702, while UE 704 is configured to connect to LTE network 706. It should be understood that there may be Figure 7 One or more initial (and intermediate) phases not shown in the figure, for example, to support conventional communications or communications between entities within the same network (e.g., gNB 102-1 and server 703 in 5G NR network 702).

[0123] In phase 1, UE 104 may receive a capability request to server 703 of 5G NR network 702. The capability request may, for example, request the UE 104 to support the capability of DSS.

[0124] In phase 2, UE 104 may provide a capability response to server 703. For example, UE 104 may indicate that UE 104 is capable of supporting DSS. UE 104 may further indicate whether UE 104 is capable of supporting rate matching around LTE PRS.

[0125] In stage 3, eNB 102-2 from LTE network 706 may provide its PRS configuration to gNB 102-1 of 5G NR network 702.

[0126] In phase 4, gNB 102-1 may request eNB 102-2 to adjust the muting pattern for the LTE PRS. For example, the muting pattern for the LTE PRS may be adjusted to enable gNB 102-1 to schedule SSBs in four consecutive OFDM symbols in an NR subframe, which are equivalent to two consecutive symbols in an LTE subframe. The request to adjust the muting pattern may be, for example, for reasons of LTE PRS density, SSB periodicity, or to avoid excessive overhead on NR data for transmitting SSBs. Furthermore, the muting pattern for the LTE PRS may be adjusted, for example, if UE 104 indicates that it does not support rate matching around the LTE PRS, so that LTE PRS muting can be used to provide NR data to UE 104.

[0127] In Stage 5, eNB 102-2 from LTE network 706 may provide its PRS configuration to gNB 102-1 of 5G NR network 702, including any adjustments to the LTE PRS muting pattern.

[0128] In stage 6, server 703 may provide DSS configuration information to UE 104 to enable UE 104 to receive NR control and data signals from gNB 102-1. For example, the DSS configuration information may include LTE PRS rate matching information, such as an LTE PRS rate matching mode, or an LTE PRS configuration, such as one or more of carrier frequency, carrier bandwidth, number of consecutive PRS subframes, PRS periodicity, PRS configuration index, muting mode, or a combination thereof. UE 104 may use this DSS configuration information to determine the LTE PRS rate matching mode. The LTE PRS rate matching information may include muting information. Additionally, the DSS configuration information may include, for example, LTE CRS rate matching information.

[0129] In Phase 7, UE 104 receives NR control signals and data signals from gNB 102-1. The NR control signals 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, data transmissions and control transmissions may be scheduled while the LTE PRS is muted.

[0130] In stage 8, while UE 104 is receiving NR control signals and data signals in stage 7, eNB 102-2 transmits an LTE PRS to UE 104. This LTE PRS is in the same spectrum as the NR control signals and data signals transmitted by gNB 102-1 and will accordingly be received by UE 104. Some LTE PRS transmitted by eNB 102-2 may be muted.

[0131] In stage 9, the UE 104 decodes and processes the NR control and data signals received in stage 7, for example, to rate match the LTE PRS transmitted in stage 8. In some implementations, the LTE PRS may also 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 does not have LTE PRS rate matching capability. If the UE 104 does not have LTE PRS rate matching capability, the UE 104 may further receive NR control and data signals, for example, during MBSFN frames.

[0132] In stage 10 , UE 704 may perform positioning measurements using the LTE PRS received in stage 8 .

[0133] Figure 8 A flow chart is shown of an example procedure 800 for wireless communications performed by a user equipment (UE), such as UE 104, connected to a New Radio (NR) network, such as 5G NR network 190, for example, for receiving LTE PRS data and control signals while NR data and control signals are transmitted on one or more frequency bands shared with a DSS.

[0134] As illustrated, at block 802, the UE receives, from an entity in the NR network, LTE PRS rate matching information for a Long Term Evolution (LTE) Positioning Reference Signal (PRS), the LTE PRS being transmitted by a base station in the LTE network (such as LTE 160) in one or more frequency bands shared with the NR network using dynamic spectrum sharing (DSS), e.g., as in Figure 7 At block 804, the UE receives NR data signals and control signals transmitted by a base station in the NR network and LTE PRS transmitted by a base station in the LTE network on one or more frequency bands, e.g., as described in Figure 7 At block 806, the UE decodes and processes the NR data signal and control signal from the base station in the NR network by performing rate matching around the LTE PRS according to the LTE PRS rate matching information, e.g., as described in Figure 7 as discussed in Stage 9.

[0135] In one implementation, the NR data signals and control signals transmitted by a base station in the 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, such as in Figure 7 as discussed in Phase 7.

[0136] In one implementation, the LTE PRS rate matching information may be an LTE PRS rate matching mode, such as in Figure 7 In another implementation, the LTE PRS rate matching information may be LTE PRS configuration data, such as in Figure 7 For example, the LTE PRS configuration data includes one or more of carrier frequency, carrier bandwidth, number of consecutive PRS subframes, PRS periodicity, PRS configuration index, muting pattern, or a combination thereof, such as described in Figure 7 discussed in Phase 6.

[0137] In one implementation, the UE may further transmit an indication of the capability to rate match around the LTE PRS in the DSS to an entity in the NR network before receiving the LTE PRS rate matching information, e.g., as in Figure 7 discussed in Phase 2.

[0138] In one implementation, the UE may further receive a muting pattern for the LTE PRS in the LTE PRS rate matching information, wherein the muting pattern is based at least in part on a synchronization signal block (SSB) periodicity from the NR network, e.g., as described in Figure 7 While the LTE PRS transmitted by the base station in the LTE network is muted, the UE may receive SSB transmissions from the base station in the NR network, e.g. Figure 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 an LTE network to reserve at least four consecutive symbols available for SSB transmission in a PRB transmitted by a base station in an NR network, e.g., as described in reference Figure 6 discussed.

[0139] Figure 9 A flowchart is shown of an example procedure 900 for wireless communications performed by a user equipment (UE), such as UE 104, connected to a New Radio (NR) network, such as 5G NR network 190, for example, for receiving NR data and control signals while LTE PRS is transmitted on one or more frequency bands shared with DSS.

[0140] As illustrated, at block 902, the UE transmits to an entity in the NR network an indication that the UE does not support rate matching around a Long Term Evolution (LTE) Positioning Reference Signal (PRS), which is transmitted by a base station in the LTE network in one or more frequency bands shared with the NR network using dynamic spectrum sharing (DSS), e.g., as in Figure 7 At block 904, the UE receives a muting pattern for the LTE PRS, e.g., as in Figure 7 At block 904, while the LTE PRS transmitted by the base station in the LTE network is muted, the UE may receive NR data signals and control signals transmitted by the base station in the NR network, e.g., as in Figure 7 as discussed in Stage 9.

[0141] In one implementation, NR data signals and control signals transmitted by a base station 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), or a combination thereof, such as in Figure 7 as discussed in Phase 7.

[0142] In one implementation, the control signal transmitted by the base station in the NR network includes a synchronization signal block (SSB), and wherein 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 reserve at least four consecutive symbols available for transmission of the SSB in the PRB transmitted by the base station in the NR network, e.g., as in Figure 6 As discussed in .

[0143] Figure 10 The diagram shows the entities in the New Radio (NR) network such as Figure 1 and 7 Flowchart of an example procedure 1000 for wireless communications performed, for example, by a base station 102-1 in a 5G NR network 190 shown in FIG. 1 for providing NR data and control signals to a UE while an LTE PRS is transmitted on one or more frequency bands shared with a DSS.

[0144] As illustrated, at block 1002, the entity obtains, from an entity in a Long Term Evolution (LTE) network, LTE Positioning Reference Signal (PRS) configuration data for an LTE PRS, the LTE PRS being transmitted in one or more frequency bands shared with a base station in an NR network using Dynamic Spectrum Sharing (DSS), e.g., as in Figure 7 At block 1004, the entity transmits LTE PRS rate matching information for an LTE PRS to a user equipment (UE) connected to a base station in the NR network, the LTE PRS being transmitted in one or more frequency bands shared with the base station in the NR network, e.g., as described in Figure 7 At block 1006, the entity transmits NR data signals and control signals to the UE on one or more frequency bands while a base station in the LTE network transmits LTE PRS, e.g., as in Figure 7 At block 1008, the UE receives and decodes the NR data signal and control signal by performing rate matching around the LTE PRS according to the LTE PRS rate matching information, e.g., as described in Figure 7 as discussed in Stage 9.

[0145] In one implementation, the NR data signals and control signals transmitted by a base station in the 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, such as in Figure 7 as discussed in Phase 7.

[0146] In one implementation, the LTE PRS rate matching information may be an LTE PRS rate matching mode, such as in Figure 7 In another implementation, the LTE PRS rate matching information may be LTE PRS configuration data, such as in Figure 7 For example, the LTE PRS configuration data includes one or more of carrier frequency, carrier bandwidth, number of consecutive PRS subframes, PRS periodicity, PRS configuration index, muting pattern, or a combination thereof, such as described in Figure 7 discussed in Phase 6.

[0147] In one implementation, the entity receives an indication from the UE regarding the capability to rate match around the LTE PRS in the DSS before transmitting the LTE PRS rate matching information to the UE, e.g., as in Figure 7 discussed in Phase 2.

[0148] In one implementation, the entity may change the muting pattern of the LTE PRS based at least in part on the synchronization signal block (SSB) periodicity from the NR network, e.g., as described in Figure 7 The modified silence pattern may be transmitted to the UE, for example as in Figure 7 The entity may transmit an SSB transmission to the UE while the LTE PRS transmitted by the base station in the LTE network is muted, for example as in Figure 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 an LTE network to reserve at least four consecutive symbols available for SSB transmission in a PRB transmitted by a base station in an NR network, for example as described in reference Figure 6 In one implementation, the entity may periodically send SSBs from the NR network to a base station in the LTE network (e.g., as in Figure 7 4) and receive a modified silence pattern from a base station in the LTE network (e.g. as discussed in Figure 7 to change the muting pattern of the LTE PRS based at least in part on the SSB periodicity from the NR network (as discussed in stage 5 of LTE PRS).

[0149] Figure 11The diagram shows the entities in the New Radio (NR) network such as Figure 1 and 7 Flowchart of an example procedure 1100 for wireless communications performed by base station 102-1 in a 5G NR network 190 shown in FIG.

[0150] As illustrated, at 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), the LTE PRS being transmitted in one or more frequency bands shared with the NR network using dynamic spectrum sharing (DSS), e.g., as in Figure 7 At block 1104, the entity schedules data transmissions and control transmissions from base stations in the NR network when the LTE PRS is muted, e.g., as in Figure 7 At block 1106, the muting pattern for the LTE PRS may be sent to the UE, e.g., as in Figure 7 At block 1108, the entity may transmit NR data signals and control signals to the UE while the LTE PRS transmitted by the base station in the LTE network is muted, for example as in Figure 7 discussed in stages 7 and 9.

[0151] In one implementation, NR data signals and control signals transmitted by a base station 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), or a combination thereof, such as in Figure 7 as discussed in Phase 7.

[0152] In one implementation, the control signal transmitted by the base station in the NR network includes a synchronization signal block (SSB), and wherein 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 reserve at least four consecutive symbols available for transmission of the SSB in the PRB transmitted by the base station in the NR network, e.g., as in Figure 6 As discussed in .

[0153] Figure 121 is a diagram illustrating an example of a hardware implementation for a user equipment (UE) 1200, such as UE 104. UE 1200 may be capable of connecting to a 5G NR wireless network (such as 5G NR network 190) that shares one or more frequency bands with an LTE network (e.g., LTE network 160) using DSS. 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 memory 1204 using one or more connections 1206 (e.g., a bus, wire, fiber, link, etc.). UE 1200 may further include additional items not shown, such as a user interface through which a user may interface with the UE, which may include, for example, a display, a keypad or other input device (such as a virtual keypad on a display), or a satellite positioning system receiver. In certain example implementations, all or a portion of UE 1200 may take the form of a chipset or the like. The wireless transceiver 1210 may include, for example, a transmitter 1212 implemented to transmit one or more signals over one or more types of wireless communication networks, and a receiver 1214 to receive one or more signals transmitted over the one or more types of wireless communication networks.

[0154] In some embodiments, the UE 1200 may include an antenna 1211, which may be internal or external. 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 between the UE antenna 1211 and the wireless transceiver 1210. For example, the measurement reference point for the received (transmitted) RF signal measurement 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 1211 having multiple UE antennas 1200 or an antenna array, the antenna connector may be considered a virtual point representing the aggregated output (input) of the multiple UE antennas. In some embodiments, 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 .

[0155] 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 the functions discussed herein by implementing one or more instructions or program codes 1220 on a non-transitory computer-readable medium, such as the medium 1208 and / or the memory 1204. In some embodiments, the one or more processors 1202 may represent one or more circuits that may be configured to perform at least a portion of a data signal computation procedure or process related to the operation of the UE 1200.

[0156] The medium 1220 and / or memory 1204 may store instructions or program code 1208 containing executable code or software instructions that, when executed by 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 illustrated in UE 1200, the medium 1220 and / or memory 1204 may include one or more components or modules that may be implemented by one or more processors 1202 to perform the methodologies described herein. Although each component or module is illustrated as software in the medium 1220 that may be executed by one or more processors 1202, it should be understood that each component or module may be stored in memory 1204 or may be dedicated hardware within or external to the one or more processors 1202.

[0157] Several software modules and data tables may reside in the media 1220 and / or memory 1204 and be utilized by the one or more processors 1202 to manage both the communications and functionality described herein. It should be appreciated that the organization of the contents of the media 1220 and / or memory 1204 as shown in the UE 1200 is merely exemplary, and as such, the functionality of the various modules and / or data structures may be combined, separated, and / or configured in various ways depending on the implementation of the UE 1200.

[0158] 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 an indication of whether the UE is capable of rate matching around an LTE PRS in a DSS to an entity in the NR network via the wireless transceiver 1210. The indication of whether the UE is capable of rate matching around an LTE PRS may be in response to a request for the indication received from the entity in the NR network.

[0159] The medium 1220 and / or the memory 1204 may include an LTE PRS rate matching information module 1224 that, when implemented by one or more processors 1202, configures the one or more processors 1202 to receive, via the wireless transceiver 1210, LTE PRS rate matching information for an LTE PRS from an entity in the NR network, the LTE PRS being transmitted by a base station in LTE in a frequency band shared with the 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.

[0160] The medium 1220 and / or the memory 1204 may include an LTE PRS muting information module 1226, which, when implemented by one or more processors 1202, configures the one or more processors 1202 to receive, via the wireless transceiver 1210, an LTE PRS muting pattern for an LTE PRS from an entity in the NR network, the LTE PRS being transmitted by a base station in LTE in a frequency band shared using a DSS.

[0161] 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 a 5G NR network. For example, the LTE PRS rate matching pattern may be an LTE PRS rate matching pattern received from an entity in a 5G NR network, or may be generated based on received LTE PRS configuration data, the 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.

[0162] The medium 1220 and / or the memory 1204 may include an NR data and control receiving module 1230, which, when implemented by one or more processors 1202, configures the one or more processors 1202 to receive NR data signals and control signals transmitted by a base station in the NR network via the wireless transceiver 1210 while the base station in the LTE network transmits an LTE PRS on one or more frequency bands shared by the DSS. As an example, the NR data signals and control signals may include one or more of a physical downlink shared channel (PDSCH) transmission, a physical downlink common channel (PDCCH) transmission, and a synchronization signal block (SSB) transmission.

[0163] The medium 1220 and / or the memory 1204 may include a module 1232 for decoding around LTE PRS, which, when implemented by the one or more processors 1202, configures the one or more processors 1202 to decode and process received NR data signals and control signals, for example, by rate matching around LTE PRS using an LTE PRS rate matching pattern. Additionally, the module 1232 for decoding around LTE PRS may configure the one or more processors 1202 to decode and process NR data signals and control signals received while the LTE PRS is muted based on a received LTE PRS muting pattern.

[0164] The methodologies described herein may be implemented by various means depending on the application. For example, the methodologies may be implemented in hardware, firmware, software, or any combination thereof. For hardware implementations, the one or more processors 1202 may be implemented within one or more application specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs), processors, controllers, microcontrollers, microprocessors, electronic devices, other electronic units designed to perform the functions described herein, or a combination thereof.

[0165] For firmware and / or software implementations, these methodologies can be implemented with modules (e.g., procedures, functions, etc.) that perform the functions described herein. Any machine-readable medium that tangibly embodies instructions can be used to implement the methodologies described herein. For example, software code can be stored in a non-transient computer-readable medium 1220 or memory 1304 that is connected to one or more processors 1204 and executed by the one or more processors 1202. Memory can be implemented within one or more processors or external to one or more processors. As used herein, the term "memory" refers to any type of long-term, short-term, volatile, non-volatile, or other memory, and is not limited to any particular type of memory or number of memories, or the type of medium on which memory is stored.

[0166] If implemented in firmware and / or software, the functionality may be stored as 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. Examples include computer-readable media encoded with data structures and computer-readable media encoded with the computer program 1208. For example, a non-transitory computer-readable medium including program code 1208 stored thereon may include program code 1208 that supports OTDOA measurements in a manner consistent with the disclosed embodiments. The non-transitory computer-readable medium 1220 includes physical computer storage media. The storage media may be any available media that can be accessed by a computer. By way of example, and not limitation, such non-transitory computer-readable media may include RAM, ROM, EEPROM, CD-ROM or other optical disk storage, magnetic disk storage, or other magnetic storage devices, or any other medium that can be used to store desired program code 1208 in the form of instructions or data structures and that can be accessed by a computer; disk and disc, as used herein, include compact disc (CD), laser disc, optical disc, digital versatile disc (DVD), floppy disk, and Blu-ray disc, where disks usually reproduce data magnetically, while discs reproduce data optically with lasers. Combinations of the above should also be included within the scope of computer-readable media.

[0167] In addition to being stored on computer-readable media 1220, instructions and / or data may also be provided as signals on a transmission medium included in a communication device. For example, the communication device may include a wireless transceiver 1210 with signals indicating instructions and data. These instructions and data are configured to cause one or more processors to implement the functions outlined in the claims. That is, the communication device includes a transmission medium with signals indicating information for performing the disclosed functions.

[0168] Memory 1204 may represent any data storage mechanism. Memory 1204 may include, for example, primary memory and / or secondary memory. Primary memory may include, for example, random access memory, read-only memory, and the like. Although illustrated in this example as being separate from one or more processors 1202, it should be understood that all or a portion of primary memory may be located within one or more processors 1202 or otherwise co-located / coupled with one or more processors 1202. Secondary memory may include, for example, the same or similar type of memory as primary memory and / or one or more data storage devices or systems (such as, for example, magnetic disk drives, optical disk drives, tape drives, solid-state memory drives, and the like).

[0169] In some implementations, the secondary storage may be operable to receive or otherwise be configurable to be coupled to the non-transitory computer-readable medium 1220. Thus, in some example implementations, the methods and / or apparatus presented herein may take the form of all or a portion of a computer-readable medium 1220 that may include computer-implementable code 1208 stored thereon, which, when executed by one or more processors 1202, may be operatively implemented to perform all or a portion of the example operations as described herein. The computer-readable medium 1220 may be part of the memory 1204.

[0170] A UE configured for wireless communication with a New Radio (NR) network, such as UE 1200, may include means for receiving, from an entity in the NR network, Long Term Evolution (LTE) Positioning Reference Signal (PRS) rate matching information for a LTE 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), the means being, for example, a wireless transceiver 1210, one or more processors 1202 having dedicated hardware or implementing executable code or software instructions in memory 1204 and / or media 1220, such as an LTE PRS rate matching information module 1224.

[0174] Figure 13A schematic block diagram illustrating certain exemplary features of a base station 1300 in a 5G NR network (e.g., base station 102 in 5G NR network 190) is shown. Base station 1300 may, for example, include one or more processors 1302, memory 1304, an external interface that may include a wireless transceiver 1310 and a communication interface 1316 (e.g., a wired or wireless network interface to other base stations and / or a core network), which may be operatively coupled to a non-transitory computer-readable medium 1320 and memory 1304 using one or more connections 1306 (e.g., a bus, wire, optical fiber, link, etc.). Base station 1300 may further include additional items not shown. In certain example implementations, all or a portion of base station 1300 may take the form of a chipset, etc. Wireless transceiver 1310 may, for example, include a transmitter 1312 implemented to transmit one or more signals over one or more types of wireless communication networks, and a receiver 1314 implemented to receive one or more signals transmitted over the one or more types of wireless communication networks. Communication interface 1316 may be a wired or wireless interface capable of connecting to other base stations or network entities in the same 5G NR network or in an LTE network that shares one or more frequency bands with base station 1300 using DSS.

[0175] In some embodiments, base station 1300 may include an antenna 1311, which may be internal or external. Antenna 1311 may be used to transmit and / or receive signals processed by wireless transceiver 1310. In some embodiments, antenna 1311 may be coupled to wireless transceiver 1310. In some embodiments, measurements of signals received (transmitted) by base station 1300 may be performed at the connection point between antenna 1311 and wireless transceiver 1310. For example, the measurement reference point for received (transmitted) RF signal measurements may be the input (output) terminal of receiver 1314 (transmitter 1312) and the output (input) terminal of antenna 1311. In base stations 1300 having multiple antennas 1311 or an antenna array, the antenna connector may be considered a virtual point representing the aggregated output (input) of the multiple antennas. In some embodiments, base station 1300 may measure received signals, including signal strength and TOA measurements, and the raw measurements may be processed by one or more processors 1302.

[0176] The one or more processors 1302 may be implemented using a combination of hardware, firmware, and software. For example, the one or more processors 1302 may be configured to perform the functions discussed herein by implementing one or more instructions or program code 1308 on a non-transitory computer-readable medium, such as the medium 1320 and / or the memory 1304. In some embodiments, the one or more processors 1302 may represent one or more circuits that may be configured to perform at least a portion of a data signal computation procedure or process related to the operation of the base station 1300.

[0177] The medium 1320 and / or memory 1304 may store instructions or program code 1308 containing executable code or software instructions that, when executed by one or more processors 1302, cause the one or more processors 1302 to operate as a special-purpose computer programmed to perform the techniques disclosed herein. As illustrated in base station 1300, the medium 1320 and / or memory 1304 may include one or more components or modules that may be implemented by one or more processors 1302 to perform the methodologies described herein. Although each component or module is illustrated as software in the medium 1320 that may be executed by one or more processors 1302, it should be understood that each component or module may be stored in memory 1304 or may be dedicated hardware within or external to one or more processors 1302.

[0178] Several software modules and data tables may reside in the media 1320 and / or memory 1304 and be utilized by the one or more processors 1302 to manage both the communications and functionality described herein. It should be appreciated that the organization of the contents of the media 1320 and / or memory 1304 as shown in the base station 1300 is merely exemplary, and as such, the functionality of the various modules and / or data structures may be combined, separated, and / or configured in different ways depending on the implementation of the base station 1300.

[0179] The medium 1320 and / or the memory 1304 may include a capability indication module 1322 that, when implemented by the one or more processors 1302, configures the one or more processors 1302 to receive an indication from a UE via the wireless transceiver 1310 regarding whether the UE is capable of rate matching around an LTE PRS in a DSS. The indication regarding whether the UE is capable of rate matching around an LTE PRS may be in response to a request for the indication transmitted to the UE via the base station 1300.

[0180] The medium 1320 and / or the memory 1304 may include an LTE PRS configuration data module 1324 that, when implemented by the one or more processors 1302, configures the one or more processors 1302 to receive LTE PRS configuration data from the LTE network via an Xn message via the communication interface 1316. The LTE PRS configuration data may include, for example, 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.

[0181] The medium 1320 and / or the memory 1304 may include an LTE PRS rate matching information module 1326 that, when implemented by the one or more processors 1302, configures the one or more processors 1302 to determine LTE PRS rate matching information and transmit the LTE PRS rate matching information to the UE via the wireless transceiver 1310. For example, the LTE PRS rate matching pattern may be generated based on received LTE PRS configuration data, the 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. In some implementations, the LTE PRS rate matching pattern may be generated by another entity in the 5G NR network based on the LTE PRS configuration data and provided to the base station 1300 via the communication interface 1316.

[0182] The medium 1320 and / or the memory 1304 may include an LTE PRS muting modification module 1328 that, when implemented by the one or more processors 1302, configures the one or more processors 1302 to modify a muting pattern of the LTE PRS. For example, the muting pattern of the LTE PRS may be modified based on the SSB periodicity. The muting pattern of the LTE PRS may be modified by requesting a base station in the LTE network to modify the muting pattern, and may include sending the SSB periodicity to a base station in the LTE network and receiving the modified muting pattern from the base station in the LTE network.

[0183] The medium 1320 and / or the memory 1304 may include an LTE PRS muting information module 1330 that, when implemented by the one or more processors 1302, configures the one or more processors 1302 to provide the modified muting pattern to the UE via the wireless transceiver 1310. In some implementations, the muting pattern for the LTE PRS may be provided to the UE in the LTE PRS rate matching information, or separately from the LTE PRS rate matching information, e.g., if the UE does not have LTE PRS rate matching capability.

[0184] The medium 1320 and / or the memory 1304 may include an NR data and control transmission module 1332, which, when implemented by one or more processors 1302, configures the one or more processors 1302 to schedule and transmit NR data signals and control signals to the UE via the wireless transceiver 1310 while a base station in the LTE network transmits an LTE PRS on one or more frequency bands shared by the DSS. As an example, the NR data signals and control signals may include one or more of a physical downlink shared channel (PDSCH) transmission, a physical downlink common channel (PDCCH) transmission, and a synchronization signal block (SSB). The NR data signals and control signals may be transmitted to the UE while the LTE PRS transmitted by the base station in the LTE network is muted.

[0185] The methodologies described herein may be implemented by various means depending on the application. For example, these methodologies may be implemented in hardware, firmware, software, or any combination thereof.

Thus, appearances of the phrases "in one example," "an example," "in some examples," or "in some implementations" or other similar phrases throughout this specification do not necessarily refer to the same feature, example, and / or limitation. Furthermore, these particular features, structures, or characteristics may be combined in one or more examples and / or features.

[0196] Some portions of the detailed description included herein are presented in the form of algorithms or symbolic representations of operations on binary digital signals stored in the memory of a specific device or a dedicated computing device or platform. In the context of this particular specification, the term specific device, etc., once programmed to perform specific operations according to instructions from program software, includes a general-purpose computer. Algorithmic descriptions or symbolic representations are examples of techniques used by those of ordinary skill in signal processing or related fields to convey the essence of their work to other technicians in the field. The algorithm here is generally considered to be a self-consistent sequence of operations or similar signal processing that leads to a desired result. In this context, the operation or processing involves the physical manipulation of physical quantities. Typically, but not necessarily, such quantities can take the form of electrical or magnetic signals that can be stored, transferred, combined, compared, or otherwise manipulated. Mainly for reasons of common use, it has proven sometimes convenient to refer to such signals as bits, data, values, elements, code elements, characters, terms, numbers, numerical values, etc. However, it should be understood that all of these or similar terms are associated with the appropriate physical quantities and are merely convenient labels. Unless otherwise specifically stated, as will be apparent from the discussion herein, it should be understood that throughout this specification, discussions utilizing terms such as "processing," "computing," "calculating," "determining," etc., refer to actions or processes of a specific apparatus, such as a special-purpose computer, special-purpose computing equipment, or similar special-purpose electronic computing device. In the context of this specification, a special-purpose computer or similar special-purpose electronic computing device is therefore capable of manipulating or transforming signals that are typically represented as physical electronic or magnetic quantities within a memory, register, or other information storage device, transmission device, or display device of the special-purpose computer or similar special-purpose electronic computing device.

[0197] In the foregoing detailed description, numerous specific details are set forth to provide a thorough understanding of the claimed subject matter. However, those skilled in the art will appreciate that the claimed subject matter may be practiced without these specific details. In other instances, methods and apparatus known to those skilled in the art have not been described in detail so as not to obscure the claimed subject matter.

[0198] As used herein, the terms "and," "or," and "and / or" may include and are intended to have various meanings that depend, at least in part, on the context in which such terms are used. Generally, "or," if used in connection with a list, such as A, B, or C, is intended to mean A, B, and C (where used in an inclusive sense) as well as A, B, or C (where used in an exclusive sense). Additionally, the term "one or more," as used herein, may be used to describe any feature, structure, or characteristic in the singular, or may be used to describe a plurality of features, structures, or characteristics, or some other combination thereof. However, it should be noted that this is merely an illustrative example, and claimed subject matter is not limited to this example.

[0199] While there has been illustrated and described what are presently considered to be example features, it will be understood by those skilled in the art that various other modifications may be made, and equivalents may be substituted, without departing from the claimed subject matter. Additionally, many modifications may be made to adapt a particular scenario to the teachings of the claimed subject matter without departing from the central concept described herein.
