[0001] [0001] This Patent Application claims the benefit of Provisional Patent Application No. U.S. 62 / 543,521 by Ly, entitled "Uplink-Based Positioning Reference Signaling in Multi-Beam Systems", filed on August 10, 2017; and U.S. Patent Application No. 16 / 058,986 to Ly, entitled "Uplink-Based Positioning Reference Signaling in Multi-Beam Systems", filed August 8, 2018; in which each is assigned to their assignee. BACKGROUND
[0002] [0002] The following generally refers to wireless communication, and, more specifically, the positioning reference signaling based on uplink in multi-beam systems.
[0003] [0003] Wireless communications systems are widely used to provide various types of communication content, such as voice, video, packet data, message, broadcast and so on. These systems may have the ability to support communication with multiple users by sharing available system sources (for example, time, frequency and power). Examples of such multiple access systems include fourth generation (4G) systems, such as Long Term Evolution (LTE) systems or Advanced LTE (LTE-A) systems, and fifth generation (5G) systems that can be called Radio Novo (NR) systems. These systems can employ technologies such as multiple code division access (CDMA), multiple time division (TDMA) access, multiple frequency division (FDMA) access, orthogonal frequency division multiple access (OFDMA), or OFDM distinct Fourier transform dispersion (DFT-S-OFDM). A wireless multi-access communications system can include a variety of base stations or network access nodes, each of which simultaneously supports communication to multiple communication devices, which may otherwise be known as communication equipment. user (UE).
[0004] [0004] In some wireless communications systems, a device, such as base stations or a UE can communicate directly with the use of beamforming techniques. In such systems, beam formation may involve the use of multiple antenna elements configured to form a beam in a particular direction. In some cases, wireless systems can support both single-beam and multi-beam system operations. For example, single beam operations may be permitted for lower frequency bands (for example, below 3 gigahertz (GHz)) while multiple beam operations may be permitted for higher frequency bands (between 3 and 6 GHz or higher).
[0005] [0005] The positioning support can be used for services of a wireless communication system (for example, emergency services). However, in some wireless communications systems, UE positioning may not be supported and as a result, the UE may resort to alternative or legacy systems with the ability to support UE positioning to provide services that depend on UE positioning. . Uplink-based positioning, also known as network-based positioning, can include a UE that sends a position reference signal (PRS) or reference signal, such as an audible reference signal (SRS), as a transmission uplink to support positioning procedures. Downlink based positioning, also known as UE based positioning, can include a base station that sends a PRS on the downlink to support positioning procedures. Such techniques may be sufficient for older wireless communications systems, however, more effective techniques for uplink based positioning in multi-beam systems may be beneficial. SUMMARY
[0006] [0006] The techniques described refer to improved methods, systems, devices or devices that support positioning reference signaling based on uplink in multi-beam systems. In general, the techniques described provide positioning reference signaling based on uplink. A user equipment (UE) can determine the beam correspondence between a set of synchronization signals (for example, which can be transmitted by a base station) and a set of transmission beams from the UE. The UE can receive a sync signal from the base station, and based on the beam match, determine a transmit beam associated with the sync signal or a receive beam used to receive the sync signal. The UE can use the determined transmission beam to determine an uplink positioning reference signal (UPRS) for the base station. This can allow the UE to avoid beam scanning through a set of transmit beams in order to transmit the UPRS to the base station.
[0007] [0007] A base station can identify a beam match between a set of synchronization signals that can be transmitted by the base station and a set of transmission beams from a UE. The base station can transmit an indication of the beam match to the UE and subsequently transmit a synchronization signal to the UE. The base station can alternatively transmit the set of beam sweep synchronization signals to a set of transmission beams. The base station can then receive a UPRS from the UE based, at least in part, on the indicated beam match.

[0050] [0050] In some wireless communications systems, such as new radio (NR) systems, devices can communicate using directional transmissions (for example, beams) allowing multiple antenna elements to form a beam in one particular direction. These wireless systems can support positioning services,
[0051] [0051] The base station can identify a beam match to transmit to a UE that can allow the UE and the service base station and / or other base stations to coordinate the transmission and reception of a reference signal from positioning. The beam match can indicate a beam configuration to be used for transmitting an uplink positioning reference signal on the basis of which the synchronization signal was received (or which receiving beam was used by the UE to receive the signal). synchronization from a base station. Once the UE receives the synchronization signal from the base station, the UE can determine the beam configuration used to receive the synchronization signal and, based on the received beam match , determine the uplink beam configuration to use to transmit the positioning reference signal.
[0052] [0052] Aspects of the disclosure are initially described in the context of wireless communications systems. Aspects are also described with reference to a process flow. The aspects of the disclosure are further illustrated and described with reference to the device diagrams, system diagrams and flowcharts that refer to the positioning reference signaling based on uplink in multi-beam systems.
[0053] [0053] Figure 1 illustrates an example of a wireless communications system 100 in accordance with various aspects of the present disclosure. The wireless communications system 100 includes base stations 105, UEs 115 and a primary network 130. In some instances, the wireless communications system 100 may be a Long Term Evolution (LTE) network, an Advanced LTE network (LTE-A) or an NR network. In some cases, the wireless communications system 100 can support improved broadband communications, ultra reliable communications (for example, mission critical), low latency communications or low cost communications and low complexity devices.
[0054] [0054] Base stations 105 can communicate wirelessly with UEs 115 through one or more base station antennas. The base stations 105 described in this document may include or may be referred to by those skilled in the art as a base transceiver station, a radio base station, an access point, a radio transceiver, a NodeB, an eNodeB ( eNB),
[0055] [0055] Each base station 105 can be associated with a particular geographical coverage area 110 in which communications with several UEs 115 are supported. Each base station 105 can provide communication coverage for a respective geographic coverage area 110 via communication links 125, and communication links 125 between a base station 105 and a UE 115 can use one or more carriers. The communication links 125 shown in the wireless communication system 100 can include uplink transmissions from a UE 115 to a base station 105, or downlink transmissions from a base station 105 to a UE 115 Downlink transmissions can also be called forward link transmissions, while uplink transmissions can also be called reverse link transmissions.
[0056] [0056] The geographical coverage area 110 for a base station 105 can be divided into sectors that make up only a portion of the geographical coverage area
[0057] [0057] The term "cell" refers to a logical communication entity used to communicate with a base station 105 (for example, through a carrier), and can be associated with an identifier to distinguish neighboring cells (for example, a physical cell identifier (PCID), a virtual cell identifier (VCID) that operates through the same carrier or a different carrier. In some instances, a carrier can support multiple cells, and different cells can be configured according to different protocol types (for example, machine-type communication (MTC), short-band Internet of Things (B-IoT), broadband enhanced mobile (eMBB), or others) that can provide access to different types of devices. In some cases, the term
[0058] [0058] UEs 115 can be dispersed via wireless communication system 100, and each UE 115 can be stationary or mobile. An UE 115 can also be called a mobile device, wireless device, remote device, portable device or subscriber device, or some other suitable terminology, where the "device" can also be called a unit, station, terminal or client. An UE 115 can also be a personal electronic device, such as a cell phone, a personal digital assistant (PDA), a tablet-type computer, a laptop-type computer, or a personal computer. In some examples, an UE 115 may also refer to a wireless local loop station (WLL), an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or an MTC device, or similar, which can be implanted in various articles, such as utensils, vehicles, meters, or similar.
[0059] [0059] Some UEs 115, such as MTC or IoT devices, can be low-cost or low-complexity devices, and can provide automated communication between machines (for example, through Machine-to-Machine (M2M) communication). M2M or MTC communication can refer to data communication technologies that allow devices to communicate with each other or with a 105 base station without human intervention. In some instances, M2M or MTC communication may include communications from devices that integrate sensors or meters to measure or capture information and relay that information to a central server or application program that makes it possible to use the information or present the information to human beings. that interact with the program or application. Some UEs 115 can be designed to collect information or allow automated machine behavior. Examples of applications for TCM devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, health care monitoring, wildlife monitoring, climatic and geological event monitoring, fleet management and tracking, remote security detection, physical access control and transaction-based business charging.
[0060] [0060] Some UEs 115 can be configured to employ operating modes that reduce power consumption, such as half-duplex communications (for example, a mode that supports one-way communication through transmission or reception, but not transmission and reception simultaneously ). In some instances, half duplex communications can be performed at a reduced peak rate. Other power conservation techniques for UEs 115 include entering a power saving "deep sleep" mode when not performing active communications, or operating over a limited bandwidth (for example, according to shortband communications ). In some cases, UEs 115 may be designed to support critical functions (for example, mission critical functions),
[0061] [0061] In some cases, a UE 115 may also have the ability to communicate directly with other UEs 115 (for example, using a point-to-point protocol (P2P) or device-to-device (D2D) ). One or more of a group of UEs 115 using D2D communications may be in the geographical coverage area 110 of a base station 105. Other UEs 115 in such a group may be outside the geographical coverage area 110 of a base station 105 , or otherwise not being able to receive transmissions from a base station 105. In some cases, groups of UEs 115 communicating via D2D communications may use a one-to-many system (1: M) in which each UE 115 transmits to all other UE 115 in the group. In some cases, a base station 105 makes it easy to program sources for D2D communications. In other cases, D2D communications are carried out between UEs 115 without the involvement of a base station 105.
[0062] [0062] Base stations 105 can communicate with main network 130 and with each other. For example, base stations 105 can interface with the main network 130 through backhaul links 132 (for example, via an SI interface or another interface). Base stations 105 can communicate with each other via backhaul links 134 (for example, via an X2 interface or another interface) directly (for example, directly between base stations 105) or indirectly (for example, through main network 130).
[0063] [0063] The main network 130 can provide user authentication, access authorization, tracing, Internet Protocol (IP) connectivity, and other access, routing or mobility functions. Core network 130 may be an evolved packet core (EPC), which may include at least one mobility management entity (MME), at least one service port (S-GW), and at least one Network port. Packet Data (PDN) (P-GW). MME can manage non-access layer functions (eg, control plan), such as mobility, authentication and bearer management for UEs 115 served by base stations 105 associated with EPC. User IP packets can be transferred via S-GW, which itself can be connected to P-GW. P-GW can provide IP address allocation as well as other functions. The P-GW can be connected to the IP services of network operators. Operator IP services may include Internet access, Intranet (s), an IP Multimedia Subsystem (IMS), or a Packet Switched Service (PS).
[0064] [0064] At least part of the network devices, such as a base station 105, may include subcomponents, such as an access network entity, which can be an example of an access node controller (ANC). Each access network entity can communicate with UEs 115 through a variety of other access network transmission entities, which can be called a radio head, an intelligent radio head, or a transmit / receive point (TRP) . In some configurations, various functions of each access network entity or base station 105 can be distributed across multiple network devices (for example, radio heads and access network controllers) or consolidated into a single network device (for example, a 105 base station).
[0065] [0065] Wireless communications system 100 can operate using one or more frequency bands, typically in the range of 300 MHz to 300 GHz. In general, the 300 MHz to 3 GHz region is known as the ultra high frequency (UHF) or decimeter band, since the wavelength range from approximately one decimeter to one meter in length. UHF waves can be blocked or redirected by buildings and environmental resources. However, the waves can penetrate sufficiently for a macrocell to provide service to 115 UEs located indoors. The transmission of UHF waves can be associated with smaller antennas and a shorter range (for example, less than 100 km) compared to the transmission using smaller frequencies and longer waves of the high frequency (HF) portion or very frequency (VHF) of the spectrum below 300 MHz.
[0066] [0066] The wireless communication system 100 can also operate in a super high frequency region (SHF) using frequency bands from 3 GHz to 30 GHz, also known as centimeter band. The SHF region includes bands, such as the 5 GHz industrial, scientific and medical (ISM) bands, which can be used in a timely manner by devices that can tolerate interference from other users.
[0067] [0067] The wireless communication system 100 can also operate in an extremely high frequency (EHF) region of the spectrum (for example, from 30 GHz to 300 GHz), also known as the millimeter band. In some instances, the wireless communications system 100 can support millimeter wave (mmW) communications between UEs 115 and base stations 105, and the EHF antennas of the respective devices can be even smaller and more closely separated than UHF antennas. . In some cases, this may facilitate the use of antenna arrays in an UE
[0068] [0068] In some cases, the wireless communications system 100 may use both licensed and unlicensed radio frequency spectrum bands. For example, wireless communications system 100 may employ Assisted Access (LAA), Unlicensed LTE-U (LTE-U) radio access technology or NR technology in an unlicensed band, such as the 5-band ISM band. GHz. When operating in unlicensed radio frequency spectrum bands, wireless devices such as base stations 105 and UEs 115 may employ listen-before-speak (LBT) procedures to ensure that a frequency channel is free before transmitting the data. In some cases, operations on unlicensed bands may be based on a CA configuration in conjunction with CCs that operate on a licensed band (for example, LAA). Unlicensed spectrum operations may include downlink transmissions, uplink transmissions, point-to-point transmissions, or a combination of these. Duplexing in unlicensed spectrum can be based on frequency division duplexing (FDD), time division duplexing (TDD), or a combination of both.
[0069] [0069] In some examples, base station 105 or UE 115 can be equipped with multiple antennas, which can be used to employ techniques, such as transmitting diversity, receiving diversity, multiple input and multiple output communications (ΜIMΟ), or beam formation. For example, the wireless communication system may use a transmission scheme between a transmission device (for example, base station 105) and a receiving device (for example, a UE 115), where the transmission device it is equipped with multiple antennas and the receiving devices are equipped with one or more antennas. MIMO communications can employ multipath signal propagation to increase spectral efficiency by transmitting or receiving multiple signals through different spatial layers, which can be called spatial multiplexing. The multiple signals can, for example, be transmitted by the transmission device via different antennas or different antenna combinations. Similarly, multiple signals can be received by the receiving device via different antennas or different antenna combinations. Each of the multiple signals can be called a separate spatial stream, and can carry bits associated with the same data stream (for example, the same keyword) or different data streams. Different spatial layers can be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single user MIMO (SU-MIMO) in which multiple spatial layers are transmitted to the same receiving device, and multiple user MIMO (MU-MIMO) in which multiple spatial layers are transmitted to multiple devices.
[0070] [0070] Beam formation, which can also be called spatial filtering, directional transmission or directional reception, is a signal processing technique that can be used on a transmitting device or a receiving device (for example, a base 105 or UE 115) to form or direct an antenna beam (e.g., a transmit beam or receive beam) along a spatial path between the transmitting device and the receiving device. Beam formation can be achieved by combining the signals communicated via antenna elements of an antenna array, so that signal propagation in particular orientations with respect to an antenna array experiences constructive interference while the others experience interference destructive. The adjustment of signals communicated by means of the antenna elements can include a transmitting device or a receiving device that applies a certain amplitude and phase compensations to signals carried through each of the antenna elements associated with the device. The adjustments associated with each of the antenna elements can be defined by forming a set of beam weights associated with a particular orientation (for example, with respect to the antenna arrangement of the transmitting or receiving device, or with respect to some other orientation).
[0071] [0071] In one example, a base station 105 can use multiple antennas or antenna arrays to conduct beamforming operations for directional communications with a UE 115. For example, some signals (eg, sync signals, signals reference signals, beam selection signals, or other control signals) can be transmitted by a base station 105 multiple times in different directions, which can include a signal that is transmitted according to different associated beamforming weight sets different directions of transmission. Transmissions in different beam directions can be used to identify (for example, base station 105 or a receiving device, such as a UE 115) a beam direction for subsequent transmission and / or reception by the base station
[0072] [0072] A receiving device (for example, a UE 115, which can be an example of an mmW receiving device) can attempt multiple receiving beams when receiving multiple signals from base station 105, such as synchronization signals , reference signals, beam selection signals or other control signals. For example, a receiving device may attempt multiple reception directions by receiving through different antenna sub-arrays, by processing signals received according to different antenna sub-arrays, by receiving according to receiving beam-forming weight sets different applied to signals received on a plurality of antenna elements of an antenna array, or by processing received signals according to different receiving beamform weight sets applied to signals received on a plurality of antenna elements of a antenna arrangement, in which any of these can be called "listening", according to different reception beams or reception directions. In some instances, a receiving device may use a single receiving beam to receive along a single beam direction (for example, when receiving a data signal). The single receiving beam can be aligned in a determined beam direction based, at least in part, on the listening, according to different receiving beam directions (for example, a determined beam direction to have a stronger signal strength) high, higher signal-to-noise ratio, or otherwise acceptable signal quality based, at least in part, on listening, according to multiple beam directions).
[0073] [0073] In some cases, the antennas of a base station 105 or a UE 115 can be located in one or more antenna arrays, which can support MDVIO operations, or transmit or receive beam formation. For example, one or more base station antennas or antenna arrays can be placed in a set of antennas, such as an antenna tower. In some cases, the antennas or antenna arrays associated with a base station 105 can be located in several geographic locations. A base station 105 can have an antenna array with a number of rows and columns of antenna ports that the base station 105 can use to support the beaming of communications with a UE 115. Similarly, a UE 115 it may have one or more antenna arrays that can withstand various MIMO operations or beam formation.
[0074] [0074] In some cases, the wireless communications system 100 may be a packet-based network that operates according to a layered protocol stack. At the user level, carrier layer or Packet Data Convergence Protocol (PDCP) communications can be IP-based. A Radio Link Control (RLC) layer can, in some cases, perform packet segmentation and regrouping to communicate through logical channels. A Medium Access Control (MAC) layer can perform priority handling and multiplexing of logical channels in transport channels. The MAC layer can also use hybrid auto-repeat request (HARQ) to provide retransmission at the MAC layer to improve link effectiveness. In the control plane, the Radio Source Control (RRC) protocol layer can provide for establishing, configuring and maintaining an RRC connection between an UE 115 and a base station 105 or main network 130 that supports radio bearers for the user plan data. In the Physical layer (PHY), transport channels can be mapped to physical channels.
[0075] [0075] In some cases, UEs 115 and base stations 105 can support data retransmissions to increase the likelihood that data will be received successfully. HARQ feedback is a technique for increasing the likelihood that data will be received correctly over a communication link
[0076] [0076] The time intervals in LTE or NR can be expressed in multiples of a basic time unit, which can, for example, refer to a sampling period of Ts = 1 / 30,720,000 seconds. The time intervals for a communications resource can be organized according to radio frames, each of which has a duration of 10 milliseconds (ms), where the frame period can be expressed as Tf = 307,200 Ts. Radio frames can be identified by a system frame number (SFN) in the range 0 to 1,023. Each frame can include 10 subframes numbered 0 to 9, and each subframe can have a duration of 1 ms. A subframe can be further divided into 2 slots, each of which has a duration of 0.5 ms, and each slot can contain 6 or 7 modulation symbol periods (for example, depending on the length of the desired cyclic prefix for each period of symbol). Excluding the cyclic prefix, each symbol period can contain 2048 sampling periods. In some cases, a subframe may be the smallest programming unit of the wireless communications system 100, and may be referred to as a transmission time interval (TTI). In other cases, a smaller programming unit of the wireless communications system 100 can be smaller than a subframe or can be dynamically selected (for example, in shortened TTI discharges (sTTIs) or in selected component carriers using sTTIs ).
[0077] [0077] In some wireless communication systems, a slot can be further divided into multiple mini-slots that contain one or more symbols. In some instances, a mini-slot or mini-slot symbol may be the smallest programming unit. Each symbol can vary in duration depending on the subcarrier spacing or the operating frequency band, for example. In addition, some wireless communications systems may implement slot aggregation in which multiple slots or minifolds are aggregated and used for communication between an UE 115 and a base station 105.
[0078] [0078] The term "carrier" refers to a set of radio frequency spectrum sources that have a physical layer structure defined to support communications over a communication link 125. For example, a carrier of a communication link 125 may include a portion of a radio frequency spectrum band that is operated according to physical layer channels by a given radio access technology. Each physical layer channel can carry user data, control information, or other signaling. A carrier can be associated with a predefined frequency channel (for example, an E-UTRA absolute radio frequency channel number (EARFCN)), and can be positioned according to a channel tracker for discovery by UEs 115. The carriers can be downlink or uplink (for example, in a FDD mode), or be configured to carry downlink and uplink communications (for example, in a TDD mode). In some examples, the signal waveforms transmitted through a carrier can be made from multiple subcarriers (for example, using multiple carrier modulation techniques (MCM), such as OFDM or DFT-s-OFDM).
[0079] [0079] The organizational structure of carriers may be different for different radio access technologies (for example, LTE, LTE-A, NR, etc.). For example, communications through a carrier can be organized according to TTIs or slots, each of which can include user data, as well as control or signaling information to support decoding of user data. A carrier may also include dedicated acquisition signaling (for example, synchronization signals or system information, etc.) and control signaling that coordinate the operation for the carrier. In some examples (for example, in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling that coordinates operations for other carriers.
[0080] [0080] Physical channels can be multiplexed on a carrier according to various techniques. A physical control channel and a physical data channel can be multiplexed on a downlink carrier, for example, using time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques or hybrid TDM-FDM techniques. In some examples, control information transmitted on a physical control channel can be cascaded between different control regions (for example, between a common control region or common search space and one or more specific control regions or specific EU search spaces).
[0081] [0081] A carrier can be associated with a particular bandwidth of the radio frequency spectrum, and in some instances, the carrier bandwidth can be termed the "system bandwidth" of the carrier or the communications system wireless 100. For example, carrier bandwidth can be one of a number of predetermined bandwidths for carriers of a particular radio access technology (for example, 1.4, 3, 5, 10, 15, 20, 40, or 80 MHz). In some instances, each served UE 115 may be configured to operate across portions or across the entire carrier bandwidth. In other examples, some UEs 115 can be configured for operation using a type of narrowband protocol that is associated with a predefined portion or range (for example, set of subcarriers or RBs) on a carrier (for example, installation "in-band" type of a narrowband protocol type).
[0082] [0082] In a system employing MCM techniques, a feature element can consist of a symbol period (for example, a modulation symbol duration) and a subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element may depend on the modulation scheme (for example, the order of the modulation scheme). Thus, the more resource elements a UE 115 receives and the higher the order of the modulation scheme, the higher data rate can be for the UE 115. In MIMO systems, a wireless communications resource can refer to a combination of a radio frequency spectrum resource, a time resource and a spatial resource (for example, spatial layers), and the use of multiple spatial layers can further increase the data rate for communications with an UE 115.
[0083] [0083] Wireless communications system devices 100 (e.g., base stations 105 or UEs 115) may have a hardware configuration that supports communications over a particular carrier bandwidth, or may be configurable to support communications through one of a set of carrier bandwidths. In some examples, wireless communications system 100 may include base stations 105 and / or UEs that can support simultaneous communications through carriers associated with more than a different carrier bandwidth.
[0084] [0084] Wireless communications systems 100 can support communication with a UE 115 in multiple cells or carriers, a feature that can be termed carrier aggregation (CA) or multiple carrier operation. A UE 115 can be configured with multiple downlink CCs and one or more uplink CCs according to a carrier aggregation configuration. Carrier aggregation can be used with both FDD and TDD component carriers.
[0085] [0085] In some cases, the wireless communications system 100 may use improved component carriers (eCCs). An eCC can be characterized by one or more features including broader carrier or frequency bandwidth, shorter symbol duration, shorter TTI duration, or modified control channel configuration. In some cases, an eCC can be associated with a carrier aggregation configuration or a dual connectivity configuration (for example, when multiple service cells have a subideal or non-ideal backhaul link). An eCC can also be configured for use on unlicensed spectrum or shared spectrum (for example, where more than one operator is allowed to use the spectrum). An eCC characterized by broad carrier bandwidth may include one or more segments that can be used by UEs 115 that do not have the capacity to monitor the entire carrier bandwidth or are otherwise configured to use a broadband bandwidth. limited carrier band (for example, to conserve power).
[0086] [0086] In some cases, an eCC may use a different symbol duration than other CCs, which may include the use of a reduced symbol duration compared to the symbol durations of the other CCs. A shorter symbol life can be associated with increased spacing between adjacent subcarriers. A device, such as an UE 115 or base station 105, that uses eCCs can transmit broadband signals (for example, according to 20, 40, 60, 80 MHz frequency or carrier bandwidths, etc.). ) at reduced symbol durations (for example, 16.67 microseconds). An eCC TTI can consist of one or multiple symbol periods. In some cases, the duration of TTI (that is, the number of symbol periods in a TTI) can be variable.
[0087] [0087] Wireless communications systems, such as an R system, can use any combination of licensed, shared and unlicensed spectrum bands, among others. The flexibility of eCC symbol duration and subcarrier spacing can allow the use of eCC across multiple spectra. In some instances, the shared NR spectrum can increase spectrum utilization and spectral efficiency, specifically through dynamic vertical (eg, over frequency) and horizontal (eg, over time) sharing of sources.
[0088] [0088] A base station 105 (or other network entity) can define a beam match between one or more synchronization signals (for example, primary synchronization signal (PSS) (such as an NR-PSS), synchronization signal secondary (SSS) (like an NR-SSS), demodulation reference signal (DMRS) (like a physical NR (PBCH) DMRS broadcast channel) and an uplink positioning reference signal (UPRS). The beam match can specify a relationship between one or more beams used to receive (for example, by UE 115) at least one of the synchronization signals and one or more transmission beams to be used for transmission (for example, by UE 115) of the UPRS. There may be different beam match configurations for uplink based positioning. Such beam-matching configurations can define beam-matching on both a UE 115 and a base station 105, beam-matching on a UE 115 only, beam-matching on a base station 105 only, or in beam-matching between UE 115 and base station 105. The beam match can be signaled in system information (for example, by an indication carried on a main information block (MIB), system information block (SIB), information minimum system requirements (ISDN), other system information (OSI), etc.). In addition, in some examples, the transmission power to the UPRS may be compensated or may depend on the measurements of synchronization signals. In some examples, the transmit power may be indicated for UE 115 (for example, in a message transmitted by base station 105 to UE 115).
[0089] [0089] Figure 2 illustrates an example of a wireless communications system 200 that supports uplink positioning reference signaling in multi-beam systems, in accordance with various aspects of the present disclosure. In some examples, wireless communications system 200 may deploy aspects of wireless communications system 100. Wireless communications system 200 may include a base station 105-a that supports communication with a UE 115-a across the area coverage 110-a. Base station 105-a and UE 115-a can communicate via communication link 215.
[0090] [0090] In some examples, base station 105- a may use beamforming techniques to communicate with UE 115-a. For example, base station 105-a can transmit a synchronization signal to UE 115-a using one or more transmission beams 205. Each transmission beam 205 can use different time frequency sources and formation the transmission beam 205 may be based on an antenna configuration at base station 105-a. UE 115-a can also use beamforming techniques in order to receive one or more synchronization signals transmitted by base station 105-a. For example, UE 115-a can use multiple antennas to form a receiving beam 210 with the ability to receive one or more synchronization signals transmitted by base station 105-a. The formation of each receiving beam 210 can be based on an antenna configuration on UE 115-a.
[0091] [0091] Base station 105-a can define a beam match between base station 105-a and UE 115-a. Beam matching can be defined with respect to synchronization signals (for example, transmitted by base station 105-a) and a UPRS (for example, to be transmitted by UE 115-a based in part on received synchronization signals ). The beam match can be base station specific, UE specific, cell specific, or specific to a group of UEs. In addition, there may be different beam match configurations defined for positioning based on uplink. Such beam-matching configurations may include beam-matching on both UE 115-a and base station 105-a, beam-matching on UE 115-a only, beam-matching on base station 105-a only, or on beam match between base station 105-a and UE 115-a.
[0092] [0092] In some cases, the base station 105-a may use one or more transmission beams 205 to transmit an indication of the beam match to the UE 115-a. In other cases, the base station 105-a can transmit the beam match indication without using beam forming techniques. The beam match indication can be transmitted before or simultaneously with the synchronization signals and, in some examples, the beam match can be transmitted in or indicated by the system information (SIB, MIB, RMSI, OSIB, etc.) . The beam match can be transmitted by the base station 105-a using the same or a different beam configuration than the one used to transmit the synchronization signals.
[0093] [0093] Based on beam matching, UE 115-a can determine an association between a receiving beam 210 through which a synchronization signal is received and an uplink beam configuration through which a UPRS can be transmitted (for example, in a correspondence case of UE 115-a and base station 105-a). Upon receipt of a synchronization signal, the UE 115-a can determine the reception beam used to receive the synchronization signal (for example, by measuring a set of received synchronization signals via a set of reception beams and determine the strongest or highest signal strength). Based on the beam match, the UE 115-a can determine the uplink beam configuration for UPRS transmission.
[0094] [0094] The UE 115-a can transmit, according to the beam matching configuration, a UPRS on the basis of which the receiving beam 210 received the synchronization signal (or the strongest synchronization signal in a case where UE 115-a receives multiple synchronization signals from one or more base stations 105-a). In some cases, the UPRS can be transmitted on the same transmission beam through which the synchronization signal is received. For example, UE 115-a can receive a synchronization signal from base station 105-a via receiving beam 210-a. Based on the beam match, the UE 115-a can determine to transmit a UPRS via beam 210-a. Alternatively, the beam match may indicate the UE 115-a to be transmitted over a beam other than the beam through which the synchronization signal was received, such as beam 210-b. In some examples, a set of synchronization signals can be transmitted by base station 105-a using multiple beams (for example, two or more between beams 205-a, 205-b, etc.) and UE 115 -a can receive multiple synchronization signals over multiple beams (for example, two or more between beams 210-a, 210-b, etc.). Based on measurements of received synchronization signals and beam matching, the UE 115-a can determine a beam 210 to be used for UPRS transmission. In some instances, the UPRS may be an audible reference signal (SRS), or a physical random access channel (PRACH), or another type of reference signal, for example another type of reference signal suitable for use as a UPRS.
[0095] [0095] In some instances, the UE 115-a may not be aware of an antenna configuration to be used for UPRS transmission (for example, in a case where no beam match is defined, or when the beam match is not received by UE 115-a, or UE 115-a moved). In such examples, the UE 115-a can perform a beam scan operation by transmitting the UPRS through multiple beams 210-a, 210-b, and so on. Additionally or alternatively, base station 105-a may not have known of a beam configuration to be used for UPRS reception (for example, in a base station-only beam match or no beam match) . In such cases, the base station 105-a can perform beam scanning through multiple receiving beams that may or may not correspond to beams 205 used for transmitting the synchronization signal (s).
[0096] [0096] For power saving mechanisms in the UE 115-a, the UE 115-a may not transition to a connected state (for example, Connected RRC state) to transmit a UPRS. For example, in some cases, the UE 115-a may send a UPRS when the UE 115-a is operating in an idle mode (for example, in Idle RRC), such as when a positioning service is required.
[0097] [0097] The UE 115-a can also adjust UPRS transmission to maintain reliable communications with base station 105-a. For example, the transmission power to the UPRS may vary depending on measurements of received synchronization signals. In some respects, fixed power compensation can be added to the transmission power of the UPRS. Power compensation can be dependent on the frequency band and / or based on the duplexing mode used for transmission (for example, TDD or FDD). In addition or alternatively, the power compensation can be signaled in system information (for example, MIB, SIB). If a 105-a base station signals a set of power compensations for the UE 115-a, the UE 115-a can select a power compensation based on the computed path loss from the measurement synchronization signal. In some cases, the UE 115-a may randomly select a power compensation from a set of power compensations when the UE 115-a transmits the UPRS. For example, the UE 115-a can randomly select a power compensation for each UPRS transmission.
[0098] [0098] Figures 3A and 3B illustrate examples of wireless communication systems 300 that support uplink positioning reference signaling in multi-beam systems, in accordance with various aspects of the present disclosure. In some examples, wireless communications system 300 may implement aspects of wireless communications systems 100 or 200, as described with reference to Figures 1 and 2.
[0099] [0099] As shown in Figure 3A, the wireless communications system 300-a includes a
[0100] [0100] The base station 105-b can communicate the beam matching configuration determined for the UE 115-b, which can be transmitted in or indicated by the system information. In one example, the beam match configuration may indicate to the UE 115-b a beam match between the base station 105-b and the UE 115-b. For example, beam matching between base station 105-b and EU 115-b may indicate an association between a receiving beam configuration (for example, used to form beam 310-a through which a sync signal is received ) of UE 115-b with transmission beam configuration of UE 115-b (for example, used to form beam 310-b through which a UPRS is transmitted).
[0101] [0101] In one example, the beam match between the base station 105-b and the UE 115-b may indicate that the UE 115-b must use the same beam configuration to transmit a UPRS as it is used to receive a signal. synchronization from base station 105- b. For example, beam matching may indicate for UE 115-b to transmit a UPRS over beam 310-a, which may be the same beam used by UE 115-b to receive a synchronization signal from base station 105 -B.
[0102] [0102] In some cases, the base station 105-b can transmit a synchronization signal using one or more 305 beams (beam 305-a, beam 305-b, etc.) to the UE 115-b. Upon receipt of the synchronization signal, the UE 115-b can determine that the receiving beam 310-b is associated with the strongest received synchronization signal and, based on the beam match, the UE 115-b can determine the beam corresponding transmission path for UE 115-b to transmit UPRS. In such an example, beam matching may indicate that the UE 115-b uses the same beam to transmit the UPRS as the one that is used to receive the synchronization signal, and thus the UE 115-b can determine to transmit the UPRS by means of beam 310-b. In another example, beam matching may indicate that UE 115-b uses a different beam to transmit the UPRS than that used to receive the synchronization signal. In such examples, although the UE 115-b receives the synchronization signal by means of beam 310-b, the beam matching can be used by the UE 115-b to determine transmit the UPRS by means of beam 310-b.
[0103] [0103] As shown in Figure 3B, the wireless communications system 300-b includes a base station 105-c that is communicating with UE 115-c. Base station 105-c can be an example of a base station associated with a service cell for UE 115-c. Base station 105-b can determine a beam-matching configuration between a set of synchronization signals (for example,
[0104] [0104] Base station 105-c can communicate the beam-matching configuration determined for UE 115-c, which can be transmitted on or indicated by system information. In one example, the beam match configuration may indicate to UE 115-c that there is no beam match between base station 105-c and EU 115-c or that there may be beam match at base station 105-c only. In such examples, base station 105-c can transmit a synchronization signal by means of one or more beams 305 to UE 115-c. Upon receipt of the synchronization signal (for example, via beam 310-d), the UE 115-c can, based on the beam match, determine one or more of the 310 beams to be used for UPRS transmission (for example, beam 310-d). For example, because there is no beam match between base station 105-c and UE 115-c or beam match only on base station 105-c, UE 115-c can perform UPRS beam scanning through each one of the beams 310 (for example, 310-c, 310-d, 310-e, 310-f). Since base station 105-c may not know which beams the UE 115-c will use for UPRS transmission, base station 105-c can also perform beam scanning through its receiving beams 305 in order to receive the UPRS.
[0105] [0105] Figure 4 illustrates an example of a wireless communications system 400 that supports positioning reference signaling based on uplink in multi-beam systems, in accordance with various aspects of the present disclosure. In some examples, wireless communications system 400 may implement aspects of wireless communications systems 100, 200, or 300, as described with reference to Figures 1 to 3.
[0106] [0106] As shown in Figure 4, the wireless communications system 400 includes a 105-d base station communicating with UE 115-d. Base station 105-d can be an example of a base station associated with a service cell 401 (e.g., a primary cell) for UE 115-d. Neighboring base station 105-e may also be in communication with UE 115-d, and may be an example of a base station associated with a secondary cell 402 for UE 115-d. In other examples, base station 105-e can support communication to secondary cell 402, but cannot be in communication with UE 115-d (for example, UE 115-d may not be configured for or connected to the base 105-e by means of secondary cell 402).
[0107] [0107] Base station 105-d can determine a beam-matching configuration for UE 115-d. In some examples, base station 105-d may alternatively receive a beam-matched configuration from a network entity or node, such as a main network entity (e.g., MME, AMF). The base station 105-d can communicate the determined beam-matching configuration to the UE 115-d, which can be transmitted on or indicated by the system information. In some cases, base station 105-e may determine a beam matching configuration for UE 115-d, which may be the same or different from the beam matching configuration determined by base station 105-d. In some examples, base station 105-e may alternatively receive a beam match configuration from a network entity or node, such as a main network entity (for example, MME, AMF) and base station 105 -e can communicate the beam match configuration determined to the UE 115-d, which can be transmitted in or indicated by the system information.
[0108] [0108] In some cases, the beam match configuration may indicate to the UE 115-d to transmit a UPRS based on the beam used to receive a synchronization signal (for example, a synchronization signal with the highest received power). For example, base station 105-d can transmit a synchronization signal via one or more beams (for example, beams 405-a, 405-b) or a neighboring base station 105-e can also transmit synchronization by means of one or more beams (for example, beams 405-c, 405-d).
[0109] [0109] Upon receipt of the sync signal (s), the UE 115-d can measure the power level received from the sync signal (s) and determine whether to transmit multiple UPRSs (for example, one UPRS to the station base 105-of a UPRS for base station 105-e). In one example, UE 115-d can receive a synchronization signal from base station 105-d via receiving beam 410-b. Based on the beam match, the UE 115-d can determine a respective transmission beam for the UPRS. For example, UE 115-d can determine to transmit a UPRS to base station 105-d via beam 410-a. In addition, UE 115-d can also receive a synchronization signal from base station 105-e via receiving beam 410-c. Based on the beam match, the UE 115-d can determine a respective transmission beam for the UPRS. For example, UE 115-d can determine to transmit a UPRS to base station 105-e via the same beam 410-c as used to receive the sync signal or a different beam (for example, beam 410-d ).
[0110] [0110] In some cases, UE 115-d may transmit UPRS only to base station 105-d associated with its service cell 401 (and may therefore not transmit a UPRS to base station 105-e ). In such examples, upon receipt of the UPRS, the base station 105-d can coordinate with any neighboring cells (for example, base station 105-e) information related to beam 410 used to transmit the UPRS, or a receiving beam 405 used by base station 105-d used to receive UPRS. Information related to beam 410 of UE 115-d or beam 405 used by base station 105-d can be exchanged through communication link 415, which can be a backhaul link. In such cases, a beam match between the UE 115-d and its base station 105-d to service cell 401 can be used, so that UE 115-d monitors for signals from the 105-d base station only. This can simplify the complexity of UE 115-d when determining parameters for transmitting the UPRS.
[0111] [0111] In some cases, the beam-matching configuration may also indicate to the UE 115-d a limit signal strength or number of signals to transmit to a set of received synchronization signals. For example, the beam matching configuration may instruct the UE 115-d to select a maximum number of UPRS to transmit, where the selected UPRS number is associated with a minimum signal strength of received synchronization signals. The synchronization signals can be transmitted from base station 105-d, neighboring base station 105-e, or a combination thereof. Upon receipt of the synchronization signal (s), the UE 115-d can determine that the power level received from the synchronization signal (s) is compatible with the limit indicated by the beam matching configuration, and can subsequently determine the beams 410 used for receiving the synchronization signal (s). Based on the beam match, the UE 115-d can determine the beams 410 to be used for transmitting one or more UPRSs. In the case where the beam match configuration is different for multiple base stations 105, no coordination between base stations 105-d and 105-e can be performed. In this way, the UE 115-d can transmit the UPRS in respective beams 410 according to multiple beam-matching configurations.
[0112] [0112] Additionally or alternatively, the beam match may instruct the UE 115-d to select a set of synchronization signals that is compatible with a threshold, and transmit a UPRS using beams 410 that correspond to beams 410 used for reception of synchronization signals that are compatible with the limit. In such cases, the UE 115-d can transmit a UPRS using one or more beams 410 based on the possibility that the synchronization signals are compatible with or exceed the limit.
[0113] [0113] Figure 5 illustrates an example process flow 500 that supports positioning reference signaling based on uplink in multi-beam systems, in accordance with various aspects of the present disclosure. In some examples, process flow 500 may implement aspects of the wireless communication system 100, 200, 300 or 400, as described with reference to Figures 1 to 4.
[0114] [0114] At 505, UE 115-e can identify a beam match between a set of sync signals and an uplink positioning reference signal, where the set of sync signals can be transmitted by the base station 105-f. The beam match can be indicated by a beam match configuration, which can be transmitted from base station 105-f.
[0115] [0115] At 510, UE 115-e can receive a synchronization signal from base station 105-f via one or more receiving beams. For example, UE 115-e can receive one or more sync signals from base station 105-f and can measure received sync signals using different receiving beams.
[0116] [0116] Optionally, in 515, the UE 115-e can receive, from the 105-f base station, a power compensation configuration that can indicate a power compensation to be used for UPRS transmission. In some examples, the power setting can be transmitted in system information.
[0117] [0117] At 520, the UE 115-e can determine a transmit beam power for a UPRS. The transmit beam power can be determined from the received power configuration (for example, transmitted by the base station 105-f in 515). Alternatively, the transmission beam power can be determined based on received synchronization signals or the power compensation can be frequency band dependent and / or duplex mode dependent. For example, the UE 115-e can measure the power received by one or more synchronization signals and determine a transmit power for the UPRS based on the measurements.
[0118] [0118] In 525, the UE 115-e can determine a transmission beam for the UE 115-and use to transmit the UPRS based, at least in part, on the received synchronization signal and on the identified beam correspondence. In some embodiments, determining the transmission beam includes identifying a receiving beam used to receive the synchronization signal, and determining an uplink transmission beam that corresponds to the receiving beam based on the beam match.
[0119] [0119] In 530, the UE 115-e can transmit the UPRS to the base station 105-f using the determined transmission beam. In some examples, transmitting the uplink positioning reference signal includes transmitting the positioning reference signal through a plurality of transmission beams including the determined transmission beam.
