1.1. Physical channels and signal transmission and reception

In a radio access system, a terminal receives information from a base station through a downlink (DL) and transmits information to the base station through an uplink (UL). Information transmitted and received between the base station and the terminal includes general data information and various control information, and various physical channels exist according to the type/use of the information they transmit and receive.

In a state in which the power is turned off, the power is turned on again, or a terminal newly entering a cell performs an initial cell search operation such as synchronizing with the base station in step S101. To this end, the terminal receives a synchronization signal block (SSB) from the base station. The SSB includes a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), and a Physical Broadcast Channel (PBCH). The UE synchronizes with the base station based on PSS/SSS and acquires information such as cell identity. In addition, the UE may acquire intra-cell broadcast information based on the PBCH. On the other hand, the UE may receive a downlink reference signal (DL RS) in the initial cell search step to check the downlink channel state.

After completing the initial cell search, the UE receives a Physical Downlink Control Channel (PDCCH) and a Physical Downlink Control Channel (PDSCH) according to information on the physical downlink control channel to receive more specific system information. can be obtained (S12).

Thereafter, the terminal may perform a random access procedure to complete access to the base station (S13 to S16). To this end, the UE transmits a preamble through a physical random access channel (PRACH) (S13), and RAR for the preamble through a physical downlink control channel and a corresponding physical downlink shared channel ( Random Access Response) may be received (S14). The UE transmits a Physical Uplink Shared Channel (PUSCH) using the scheduling information in the RAR (S15), and a contention resolution procedure such as reception of a physical downlink control channel signal and a corresponding physical downlink shared channel signal. ) can be performed (S16).

On the other hand, when the random access process is performed in two steps (2-step RACH, type-2 random access procedure) other than the random access process (4-step RACH, type-1 random access procedure) performed in the above 4 steps (2-step RACH, type-2 random access procedure) , S13/S15 are performed as one operation in which the terminal performs transmission (eg, transmission operation of message A including a PRACH preamble and/or PUSCH), and S14/S16 is one operation in which the base station performs transmission operation (eg, transmission operation of message B including RAR and/or collision resolution information).

After performing the procedure as described above, the UE performs reception of a physical downlink control channel signal and/or a shared physical downlink channel signal (S17) and a shared physical uplink channel (PUSCH) as a general up/downlink signal transmission procedure thereafter. Transmission (S18) of an Uplink Shared Channel) signal and/or a Physical Uplink Control Channel (PUCCH) signal may be performed.

Control information transmitted by the terminal to the base station is collectively referred to as uplink control information (UCI). UCI includes HARQ-ACK/NACK (Hybrid Automatic Repeat and reQuest Acknowledgment/Negative-ACK), SR (Scheduling Request), CQI (Channel Quality Indication), PMI (Precoding Matrix Indication), RI (Rank Indication) information, etc. .

UCI is generally transmitted periodically through PUCCH, but may be transmitted through PUSCH when control information and data are to be transmitted simultaneously. In addition, according to a request/instruction of a network, the UE may aperiodically transmit UCI through PUSCH.

1.2. 물리 자원1.2. physical resource

The NR system can support multiple Numerology. Here, the numerology may be defined by a subcarrier spacing (SCS) and a cyclic prefix (CP) overhead. In this case, the plurality of subcarrier spacings may be derived by scaling the basic subcarrier spacing by an integer N (or μ). Also, assuming that very low subcarrier spacing is not used at very high carrier frequencies, the numerology used can be selected independently of the frequency band of the cell. In addition, in the NR system, various frame structures according to a number of numerologies may be supported.

Hereinafter, orthogonal frequency division multiplexing (OFDM) numerology and frame structure that can be considered in the NR system will be described. A number of OFDM numerologies supported in the NR system may be defined as shown in Table 1. The μ and cyclic prefix for the bandwidth part are obtained from the RRC parameters provided by the BS.

NR supports multiple numerologies (eg, subcarrier spacing) to support various 5G services. For example, when the subcarrier spacing is 15kHz, it supports a wide area in traditional cellular bands, and when the subcarrier spacing is 30kHz/60kHz, dense-urban, lower latency latency) and wider carrier bandwidth, and when subcarrier spacing is 60 kHz or higher, a bandwidth greater than 24.25 GHz is supported to overcome phase noise.

The NR frequency band is defined by two types of frequency ranges, FR1 and FR2. FR1 is a sub 6GHz range, and FR2 is a millimeter wave (mmWave) in the above 6GHz range.

Table 2 below illustrates the definition of the NR frequency band.

Regarding the frame structure in the NR system, the size of various fields in the time domain is expressed as a multiple of T _c = 1/(Δ f _max * N _f ), which is a basic time unit for NR. . Here, △ f _max = 480*10 ³ Hz, and N _f = 4096, which is a value related to the size of a fast Fourier transform (FFT) or an inverse fast Fourier transform (IFFT). T _c has the following relationship with T _s = 1/((15kHz)*2048), which is the base time unit for LTE and the sampling time: T _s / T _c = 64. Downlink and uplink transmissions are T _f = (Δ f _max * N _f /100)* T _c = organized into (radio) frames of 10 ms duration. Here, each radio frame is composed of 10 subframes each having a duration of T _sf = (Δ f _max * N _f /1000) * T _c = 1 ms. There may be one set of frames for uplink and one set of frames for downlink. For the numerology μ , the slots are numbered n ^μ _s ∈ {0,..., N ^slot,μ _subframe -1} in increasing order within the subframe, and within the radio frame In ascending order, they are numbered n ^μ _s,f ∈ {0,..., N ^slot,μ _frame -1}. One slot consists of N ^μ _symb consecutive OFDM symbols, and N ^μ _symb depends on a cyclic prefix (CP). The start of slot n ^μ _s in a subframe is temporally aligned with the start of OFDM symbol n ^μ _s * N ^μ _symb in the same subframe.

Table 3 shows the number of symbols per slot, the number of slots per frame, and the number of slots per subframe according to the SCS when the normal CP is used, and Table 4 shows the number of symbols per slot according to the SCS when the extended CSP is used. Indicates the number of symbols, the number of slots per frame, and the number of slots per subframe.

In the above table, N ^slot _symb indicates the number of symbols in a slot, N ^{frame, μ} _slot indicates the number of slots in a frame, and N ^{subframe, μ} _slot indicates the number of slots in a subframe.

In an NR system to which various embodiments are applicable, OFDM(A) numerology (eg, SCS, CP length, etc.) may be set differently between a plurality of cells merged into one UE. Accordingly, the (absolute time) interval of a time resource (eg, SF, slot, or TTI) (commonly referred to as TU (Time Unit) for convenience) composed of the same number of symbols may be set differently between the merged cells.

FIG. 2 is an example of a case where μ = 2 (ie, a subcarrier spacing of 60 kHz). Referring to Table 3, one subframe may include four slots. One subframe = {1,2,4} slots shown in FIG. 2 is an example, and the number of slot(s) that can be included in one subframe is defined as in Table 3 or Table 4.

Also, a mini-slot may contain 2, 4, or 7 symbols or may contain more or fewer symbols.

In relation to a physical resource in the NR system, an antenna port, a resource grid, a resource element, a resource block, a carrier part, etc. can be considered. Hereinafter, the physical resources that can be considered in the NR system will be described in detail.

First, with respect to an antenna port, an antenna port is defined such that a channel through which a symbol on an antenna port is conveyed can be inferred from a channel through which another symbol on the same antenna port is conveyed. When a large-scale property of a channel carrying a symbol on one antenna port can be inferred from a channel carrying a symbol on another antenna port, the two antenna ports are QCL (quasi co-located or quasi It can be said that there is a co-location relationship. Here, the wide range characteristics include delay spread, Doppler spread, frequency shift, average received power, received timing, average delay, It includes one or more of spatial (spatial) reception (Rx) parameters. The spatial Rx parameter refers to a spatial (reception) channel characteristic parameter such as an angle of arrival.

may be different between uplink and downlink as well as SCS (subcarrier spacing) configuration μ. There is one resource grid for SCS configuration μ, antenna port p, and transmission direction (uplink or downlink). Each element of the resource grid for the SCS configuration μ and antenna port p is referred to as a resource element, and is uniquely identified by an index pair (k,l), where k is an index in the frequency domain. and l refers to the symbol position in the frequency domain relative to the reference point. The resource element (k,l) for the SCS configuration μ and the antenna port p is a physical resource and a complex value.

corresponds to A resource block (RB) in the frequency domain

It is defined as consecutive (consecutive) subcarriers.

Considering that the UE may not be able to support the wide bandwidth to be supported in the NR system at once, the UE may be configured to operate in a part of the cell's frequency bandwidth (bandwidth part (BWP)).

A DL control channel, DL or UL data, and a UL control channel may all be included in one slot. For example, the first N symbols in a slot may be used to transmit a DL control channel (hereinafter, DL control region), and the last M symbols in a slot may be used to transmit a UL control channel (hereinafter, UL control region). N and M are each an integer greater than or equal to 0. A resource region (hereinafter, referred to as a data region) between the DL control region and the UL control region may be used for DL data transmission or UL data transmission. A time gap for DL-to-UL or UL-to-DL switching may exist between the control region and the data region. The PDCCH may be transmitted in the DL control region, and the PDSCH may be transmitted in the DL data region. Some symbols at the time of switching from DL to UL in a slot may be used as a time gap.

The base station transmits a related signal to the terminal through a downlink channel to be described later, and the terminal receives the related signal from the base station through a downlink channel to be described later.

PDSCH carries downlink data (eg, DL-shared channel transport block, DL-SCH TB), and modulation methods such as Quadrature Phase Shift Keying (QPSK), 16 Quadrature Amplitude Modulation (QAM), 64 QAM, and 256 QAM are available. applies. A codeword is generated by encoding the TB. The PDSCH can carry up to two codewords. Scrambling and modulation mapping are performed for each codeword, and modulation symbols generated from each codeword are mapped to one or more layers (Layer mapping). Each layer is mapped to a resource together with a demodulation reference signal (DMRS), is generated as an OFDM symbol signal, and is transmitted through a corresponding antenna port.

In the PDCCH, downlink control information (DCI), for example, DL data scheduling information, UL data scheduling information, etc. may be transmitted. In PUCCH, Uplink Control Information (UCI), for example, ACK/NACK (Positive Acknowledgment/Negative Acknowledgment) information for DL data, CSI (Channel State Information) information, SR (Scheduling Request), etc. may be transmitted.

The PDCCH carries downlink control information (DCI) and the QPSK modulation method is applied. One PDCCH is composed of 1, 2, 4, 8, or 16 CCEs (Control Channel Elements) according to an Aggregation Level (AL). One CCE consists of six REGs (Resource Element Groups). One REG is defined as one OFDM symbol and one (P)RB.

The PDCCH is transmitted through a Control Resource Set (CORESET). CORESET is defined as a set of REGs with a given numerology (eg SCS, CP length, etc.). A plurality of OCRESETs for one UE may overlap in the time/frequency domain. CORESET may be set through system information (eg, MIB) or UE-specific higher layer (eg, Radio Resource Control, RRC, layer) signaling. Specifically, the number of RBs and the number of symbols (maximum 3) constituting CORESET may be set by higher layer signaling.

The UE obtains DCI transmitted through the PDCCH by performing decoding (aka, blind decoding) on the set of PDCCH candidates. A set of PDCCH candidates decoded by the UE is defined as a PDCCH search space set. The search space set may be a common search space or a UE-specific search space. The UE may acquire DCI by monitoring PDCCH candidates in one or more search space sets configured by MIB or higher layer signaling.

The terminal transmits a related signal to the base station through an uplink channel to be described later, and the base station receives the related signal from the terminal through an uplink channel to be described later.

PUSCH carries uplink data (eg, UL-shared channel transport block, UL-SCH TB) and/or uplink control information (UCI), and CP-OFDM (Cyclic Prefix - Orthogonal Frequency Division Multiplexing) waveform (waveform) Alternatively, DFT-s-OFDM (Discrete Fourier Transform - spread - Orthogonal Frequency Division Multiplexing) is transmitted based on the waveform. When the PUSCH is transmitted based on the DFT-s-OFDM waveform, the UE transmits the PUSCH by applying transform precoding. For example, when transform precoding is not possible (eg, transform precoding is disabled), the UE transmits a PUSCH based on the CP-OFDM waveform, and when transform precoding is possible (eg, transform precoding is enabled), the UE transmits the CP-OFDM PUSCH may be transmitted based on a waveform or a DFT-s-OFDM waveform. PUSCH transmission is dynamically scheduled by a UL grant in DCI, or based on higher layer (eg, RRC) signaling (and/or Layer 1 (L1) signaling (eg, PDCCH)) semi-statically. Can be scheduled (configured grant). PUSCH transmission may be performed on a codebook-based or non-codebook-based basis.

PUCCH carries uplink control information, HARQ-ACK and/or scheduling request (SR), and is divided into Short PUCCH and Long PUCCH according to the PUCCH transmission length.

2. 측위 (positioning)2. Positioning

Positioning may mean determining the geographic location and/or speed of the UE by measuring a radio signal. The location information may be requested by a client (eg, an application) associated with the UE and reported to the client. In addition, the location information may be included in the core network or may be requested by a client connected to the core network. The location information may be reported in a standard format such as cell-based or geographic coordinates, and in this case, the estimation error value for the location and speed of the UE and/or the positioning method used for positioning. We can report together.

LPP allows the target device and the location server to exchange measurement and/or location information based on signal A and/or signal B.

New generation evolved-NB (ng-eNB) and gNB are network elements of NG-RAN that can provide a measurement result for location tracking, and can measure a radio signal for a target UE and deliver the result to the LMF. . In addition, the ng-eNB may control some TPs (Transmission Points) such as remote radio heads or PRS-only TPs supporting a PRS-based beacon system for E-UTRA.

The LMF is connected to an Enhanced Serving Mobile Location Center (E-SMLC), and the E-SMLC may enable the LMF to access the E-UTRAN. For example, the E-SMLC uses a downlink measurement obtained by the target UE through a signal transmitted from the LMF eNB and/or PRS-dedicated TPs in the E-UTRAN to OTDOA, which is one of the positioning methods of the E-UTRAN. (Observed Time Difference Of Arrival) can be supported.

Meanwhile, the LMF may be connected to a SUPL Location Platform (SLP). The LMF may support and manage different location services for target UEs. The LMF may interact with the serving ng-eNB or serving gNB for the target UE to obtain the UE's location measurement. For positioning of the target UE, the LMF is a Location Service (LCS) client type, required Quality of Service (QoS), UE positioning capabilities, gNB positioning capabilities and ng-eNB positioning capabilities based on a positioning method based on and may apply this positioning method to the serving gNB and/or the serving ng-eNB. Then, the LMF may determine a position estimate for the target UE and additional information such as accuracy of the position estimate and velocity. The SLP is a SUPL (Secure User Plane Location) entity responsible for positioning through a user plane.

The UE may measure the location of the UE by using a downlink reference signal transmitted from the NG-RAN and the E-UTRAN. In this case, the downlink reference signal transmitted from the NG-RAN and the E-UTRAN to the UE may include an SS/PBCH block, CSI-RS and/or PRS, etc., and the location of the UE using any downlink reference signal. Whether to measure the LMF/E-SMLC/ng-eNB/E-UTRAN may depend on a setting. In addition, RAT utilizing different Global Navigation Satellite System (GNSS), Terrestrial Beacon System (TBS), Wireless local area network (WLAN) access point, Bluetooth beacon, and a sensor (eg, barometric pressure sensor) embedded in the UE, etc. - It is also possible to measure the location of the UE in an independent manner. The UE may include the LCS application, and may access the LCS application through communication with a network to which the UE is connected or other applications included in the UE. The LCS application may include measurement and calculation functions necessary to determine the location of the UE. For example, the UE may include an independent positioning function such as Global Positioning System (GPS), and may report the location of the UE independently of NG-RAN transmission. The independently acquired positioning information may be utilized as auxiliary information of positioning information acquired from the network.

2.4. UE의 위치 측정을 위한 동작2.4. Operation for UE location measurement

When the UE is in the CM-IDLE (Connection Management - IDLE) state, when the AMF receives a location service request, the AMF establishes a signaling connection with the UE, and provides a network trigger service to allocate a specific serving gNB or ng-eNB you can request This operation process is omitted in FIG. 7 . That is, in FIG. 7 , it may be assumed that the UE is in a connected mode. However, the signaling connection may be released during the positioning process by the NG-RAN for reasons such as signaling and data inactivity.

Referring to the operation process of the network for measuring the location of the UE in detail with reference to FIG. 7 , in step 1a, a 5GC entity such as a GMLC may request a location service for measuring the location of a target UE as a serving AMF. However, even if the GMLC does not request the location service, according to step 1b, the serving AMF may determine that the location service is necessary for measuring the location of the target UE. For example, to measure the location of the UE for an emergency call (emergency call), the serving AMF may determine to directly perform a location service.

Then, according to step 2, the AMF sends a location service request to the LMF, and according to step 3a, the LMF serves location procedures for obtaining location measurement data or location measurement assistance data ng-eNB; You can start with the serving gNB. For example, the LMF may request the NG-RAN for location-related information related to one or more UEs, and may indicate the type of location information required and the associated QoS. Then, in response to the request, the NG-RAN may transmit location-related information to the LMF to the LMF. In this case, when the method for determining the location by the request is E-CID, the NG-RAN may transmit additional location-related information to the LMF through one or more NRPPa messages. Here, 'location-related information' may mean all values used for location calculation, such as actual location estimation information and wireless measurement or location measurement. In addition, the protocol used in step 3a may be an NRPPa protocol, which will be described later.

Additionally, according to step 3b, the LMF may initiate location procedures for downlink positioning with the UE. For example, the LMF may send location assistance data to the UE, or obtain a location estimate or location measurement. For example, a capability transfer process may be performed in step 3b. Specifically, the LMF may request capability information from the UE, and the UE may transmit capability information to the LMF. In this case, the capability information refers to various aspects of a specific location measurement method, such as information on a location measurement method that can be supported by LFM or UE, and various types of assistance data for A-GNSS. ) and information on common features that are not limited to any one location measurement method, such as the ability to handle multiple LPP transactions, and the like. Meanwhile, in some cases, even if the LMF does not request capability information from the UE, the UE may provide capability information to the LMF.

As another example, in step 3b, a location assistance data transfer (Assistance data transfer) process may be performed. Specifically, the UE may request location assistance data from the LMF, and may indicate required specific location assistance data to the LMF. Then, the LMF may transmit location assistance data corresponding thereto to the UE, and additionally, may transmit additional assistance data to the UE through one or more additional LPP messages. On the other hand, the location assistance data transmitted from the LMF to the UE may be transmitted through a unicast method, and in some cases, without the UE requesting the assistance data from the LMF, the LMF sends the location assistance data and / Alternatively, additional assistance data may be transmitted to the UE.

As another example, a location information transfer process may be performed in step 3b. Specifically, the LMF may request the UE for location-related information related to the UE, and may indicate the type of location information required and the related QoS. Then, in response to the request, the UE may transmit the location-related information to the LMF to the LMF. In this case, the UE may additionally transmit additional location-related information to the LMF through one or more LPP messages. Here, 'location-related information' may mean all values used for location calculation, such as actual location estimation information and radio measurement or location measurement, representatively from a plurality of NG-RANs and/or E-UTRANs. There may be a reference signal time difference (RSTD) value measured by the UE based on downlink reference signals transmitted to . Similar to the above, the UE may transmit the location-related information to the LMF even if there is no request from the LMF.

Meanwhile, the processes performed in step 3b described above may be performed independently or may be performed continuously. In general, step 3b is performed in the order of a capability transfer process, an assistance data transfer process, and a location information transfer process, but is not limited to this order. In other words, step 3b is not limited to a specific order in order to improve the flexibility of location measurement. For example, the UE may request location assistance data at any time to perform a location measurement request already requested by the LMF. In addition, when the LMF does not satisfy the QoS required by the location information delivered by the UE, the LMF may request location information such as a location measurement value or a location estimate at any time. Similarly, when the UE does not perform measurement for position estimation, capability information may be transmitted to the LMF at any time.

In addition, when an error occurs in the information or request exchanged between the LMF and the UE in step 3b, an Error message may be transmitted/received, and an Abort message may be transmitted/received for stopping location measurement.

Meanwhile, the protocol used in step 3b may be an LPP protocol, which will be described later.

Meanwhile, step 3b may be additionally performed after step 3a is performed, or may be performed instead of step 3a.

In step 4, the LMF may provide a location service response to the AMF. In addition, the location service response may include information on whether the location estimation of the UE was successful and the location estimate of the UE. After that, if the procedure of FIG. 7 is initiated by step 1a, the AMF may transmit a location service response to a 5GC entity such as a GMLC, and if the procedure of FIG. 7 is initiated by step 1b, the AMF is a location related to an emergency call, etc. For service provision, a location service response may be used.

2.5. 위치 측정을 위한 프로토콜2.5. Protocol for Position Measurement

LTE Positioning Protocol (LPP)

9 is a diagram illustrating an example of a protocol layer for supporting LTE positioning protocol (LPP) message transmission to which various embodiments are applicable. The LPP PDU may be transmitted through a NAS PDU between an Access and Mobility Management Function (AMF) and the UE.

Referring to FIG. 9 , the LPP includes a target device (eg, a UE in the control plane or a SUPL Enabled Terminal (SET) in the user plane) and a location server (eg, LMF in the control plane or SLP in the user plane). ) can be terminated. The LPP message may be delivered in the form of a transparent PDU through an intermediate network interface using an appropriate protocol such as NGAP through the NG-C interface, NAS/RRC through the LTE-Uu and NR-Uu interfaces. The LPP protocol enables positioning for NR and LTE using multiple positioning methods.

For example, through the LPP protocol, the target device and the location server may exchange capability information, exchange auxiliary data for positioning, and/or exchange location information. In addition, error information exchange and/or an instruction to stop the LPP procedure may be performed through the LPP message.

NR Positioning Protocol A (NRPPa)

10 is a diagram illustrating an example of a protocol layer for supporting NR positioning protocol a (NRPPa) protocol data unit (PDU) transmission to which various embodiments are applicable.

NRPPa may be used for information exchange between the NG-RAN node and the LMF. Specifically, NRPPa may exchange E-CID for measurement transmitted from ng-eNB to LMF, data for supporting OTDOA positioning method, Cell-ID and Cell location ID for NR Cell ID positioning method, and the like. The AMF may route NRPPa PDUs based on the routing ID of the associated LMF through the NG-C interface even if there is no information on the associated NRPPa transaction.

The procedures of the NRPPa protocol for location and data collection can be divided into two types. The first type is a UE associated procedure for transmitting information about a specific UE (eg, location measurement information, etc.), and the second type is information applicable to the NG-RAN node and related TPs ( For example, it is a non-UE associated procedure for transmitting gNB/ng-eNG/TP timing information, etc.). The two types of procedures may be supported independently or may be supported simultaneously.

2.6. 측위 방법 (Positioning Measurement Method)2.6. Positioning Measurement Method

The positioning methods supported by NG-RAN include GNSS (Global Navigation Satellite System), OTDOA, E-CID (enhanced cell ID), barometric pressure sensor positioning, WLAN positioning, Bluetooth positioning and TBS (terrestrial beacon system), UTDOA (Uplink Time). Difference of Arrival) and the like. Among the positioning methods, any one positioning method may be used to measure the location of the UE, but two or more positioning methods may be used to measure the location of the UE.

OTDOA (Observed Time Difference Of Arrival)

11 is a diagram illustrating an example of an observed time difference of arrival (OTDOA) positioning method to which various embodiments are applicable.

The OTDOA positioning method uses the measurement timing of downlink signals received by the UE from multiple TPs including an eNB, an ng-eNB, and a PRS dedicated TP. The UE measures the timing of the received downlink signals by using the location assistance data received from the location server. In addition, the location of the UE may be determined based on the measurement result and the geographic coordinates of the neighboring TPs.

A UE connected to the gNB may request a measurement gap for OTDOA measurement from the TP. If the UE does not recognize the SFN for at least one TP in the OTDOA assistance data, the UE requests a measurement gap for performing a Reference Signal Time Difference (RSTD) measurement. OTDOA reference cell (reference cell) An autonomous gap can be used to obtain an SFN of .

Here, the RSTD may be defined based on the smallest relative time difference between the boundaries of two subframes respectively received from the reference cell and the measurement cell. That is, it may be calculated based on a relative time difference between the start time of the subframe of the closest reference cell and the start time of the subframe received from the measurement cell. Meanwhile, the reference cell may be selected by the UE.

For accurate OTDOA measurement, it is necessary to measure the time of arrival (TOA) of a signal received from three or more geographically dispersed TPs or base stations. For example, measure the TOA for each of TP 1, TP 2 and TP 3, and based on the three TOAs, the RSTD for TP 1-TP 2, RSTD for TP 2-TP 3, and TP 3-TP 1 By calculating the RSTD, a geometric hyperbola can be determined based on this, and a point where the hyperbola intersects can be estimated as the location of the UE. In this case, since accuracy and/or uncertainty for each TOA measurement may occur, the estimated location of the UE may be known as a specific range according to the measurement uncertainty.

For example, the RSTD for the two TPs may be calculated based on Equation (5).

[Equation 5]

c is the speed of light,

is the (unknown) coordinates of the target UE,

is the coordinates of the (known) TP,

may be the coordinates of the reference TP (or other TP). here,

is a transmission time offset between two TPs, which may be referred to as “Real Time Differences” (RTDs), and n _i and n ₁ may represent values related to UE TOA measurement errors.

E-CID (Enhanced Cell ID)

In the cell ID (CID) positioning method, the location of the UE may be measured through geographic information of the UE's serving ng-eNB, serving gNB and/or serving cell. For example, geographic information of the serving ng-eNB, the serving gNB, and/or the serving cell may be obtained through paging, registration, or the like.

Meanwhile, the E-CID positioning method may use additional UE measurement and/or NG-RAN radio resources for improving the UE position estimate in addition to the CID positioning method. In the E-CID positioning method, some of the same measurement methods as the measurement control system of the RRC protocol may be used, but in general, additional measurement is not performed only for the location measurement of the UE. In other words, a separate measurement configuration or measurement control message may not be provided to measure the location of the UE, and the UE does not expect that an additional measurement operation only for location measurement will be requested. , the UE may report a measurement value obtained through generally measurable measurement methods.

For example, the serving gNB may implement the E-CID positioning method using the E-UTRA measurement provided from the UE.

* Examples of measurement elements that can be used for E-CID positioning may be as follows.

- UE measurement: E-UTRA RSRP (Reference Signal Received Power), E-UTRA RSRQ (Reference Signal Received Quality), UE E-UTRA reception-transmission time difference (Rx-Tx Time difference), GERAN/WLAN RSSI (Reference Signal Strength) Indication), UTRAN CPICH (Common Pilot Channel) RSCP (Received Signal Code Power), UTRAN CPICH Ec/Io

- E-UTRAN measurement: ng-eNB reception-transmission time difference (Rx-Tx Time difference), timing advance (Timing Advance; T _ADV ), Angle of Arrival (AoA)

Here, T _ADV may be divided into Type 1 and Type 2 as follows.

T _ADV Type 1 = (ng-eNB reception-transmission time difference) + (UE E-UTRA reception-transmission time difference)

T _ADV Type 2 = ng-eNB receive-transmit time difference

On the other hand, AoA may be used to measure the direction of the UE. AoA may be defined as an estimated angle for the position of the UE in a counterclockwise direction from the base station/TP. In this case, the geographic reference direction may be north. The base station/TP may use an uplink signal such as a sounding reference signal (SRS) and/or a demodulation reference signal (DMRS) for AoA measurement. In addition, the larger the antenna array arrangement, the higher the AoA measurement accuracy. When the antenna arrays are arranged at the same interval, signals received from adjacent antenna elements may have a constant phase-rotate.

Multi RTT (Multi-cell RTT)

12 is a diagram illustrating an example of a Multi RTT (round trip time) positioning method to which various embodiments are applicable.

Referring to FIG. 12A , an RTT process in which TOA measurement is performed by an initiating device and a responding device, and the responding device provides TOA measurement to an initiating device for RTT measurement (calculation) is exemplified. For example, the initiating device may be a TRP and/or a terminal, and the responding device may be a terminal and/or a TRP.

In operation 1301 according to various embodiments, the initiating device may transmit an RTT measurement request, and the responding device may receive it.

In operation 1305 according to various embodiments, the responding device may transmit an RTT measurement signal at t ₂ , and the initiating device may acquire a TOA measurement t ₃ .

In operation 1307 according to various embodiments, the responding device may transmit information on [t ₂ -t ₁ ], and the initiating device may receive the information and calculate the RTT based on Equation (6). Corresponding information may be transmitted/received based on a separate signal, or may be transmitted/received by being included in the RTT measurement signal of 1305.

[Equation 6]

Referring to FIG. 12 (b) , the RTT may correspond to double-range measurement between two devices. Positioning estimation may be performed from the corresponding information. Based on the measured RTT, d ₁ , d ₂ , d ₃ can be determined, and the circumferences centered on each BS ₁ , BS ₂ , BS ₃ (or TRP) and with each d ₁ , d ₂ , d ₃ as the radius. The target device location can be determined by the intersection of

2.7. Sounding Procedure2.7. Sounding Procedure

In a wireless communication system to which various embodiments are applicable, a sounding reference signal (SRS) for positioning may be used.

An SRS -Config information element (IE) may be used to configure SRS transmission. SRS resource (list of) and/or SRS resource set (list of) may be defined, and each resource set may define a set of SRS resources.

SRS-Config may include SRS configuration information (for other purposes) and SRS configuration information for positioning separately. For example, the configuration information of the SRS resource set for SRS (for other purposes) (eg, SRS-ResourceSet ) and the configuration information of the SRS resource set for SRS for positioning (eg, SRS-PosResourceSet ) are may be included separately. In addition, for example, (for other purposes) SRS resource configuration information for SRS (eg, SRS-ResourceSet ) and SRS resource configuration information for SRS for positioning (eg, SRS-PosResource ) are may be included separately.

The SRS resource set for positioning may include one or more SRS resources for positioning. Information for setting the SRS resource set for positioning includes information on ID (identifier) that is assigned/allocated/corresponding to the SRS resource set for positioning, and is assigned/allocated/corresponding to each of one or more SRS resources for included positioning. ID may be included. For example, information for configuring an SRS resource for positioning may include an ID assigned/allocated/corresponding to a UL resource. For example, an SRS resource/SRS resource set for each positioning may be identified based on each assigned/allocated/corresponding ID.

The SRS may be set to periodic/semi-persistent/aperiodic.

Aperiodic SRS may be triggered from DCI. DCI may include an SRS request field.

An example of the SRS request field may refer to Table 6.

In Table 6, srs-TPC-PDCCH-Group is a parameter that sets the triggering type for SRS transmission to typeA or typeB, and aperiodicSRS-ResourceTriggerList is DCI "code points" at which the UE must transmit SRS according to the SRS resource set configuration. is a parameter to set an additional list of, aperiodicSRS-ResourceTrigger is a parameter to set the DCI "code point" at which SRS should be transmitted according to the SRS resource set setting, and resourceType is a time domain action (time) of the SRS resource setting. domain behavior) (periodic/semi-static/aperiodic).

제안#1 : hierarchical positioning measurement reportingProposal #1: hierarchical positioning measurement reporting

According to various embodiments, the UE reports the positioning measurement and/or location estimate value of C (where C=A+B, A, B, C>=0) to the base station/location server, respectively, the A value and the B value can be reported to the base station / location server. According to various embodiments, the timing of reporting the A value and the B value may be the same or different.

According to various embodiments, when reporting the A value and the B value, a time-stamp for indicating a time interval in which the value A is valid and a time-stamp indicating a time interval in which the value B is valid are provided. Can be set independently. For example, a time-stamp #A for measurement value reporting of “A” and a time-stamp #B for reporting the measurement value of B may be independently set. there is.

14 is an example of a table usable for a location measurement report according to various embodiments of the present disclosure. For example, FIG. 14 may be used for hierarchical measurement report associated with different/independent time-stamps. For example, the unit of the time-stamp may be milliseconds (ms), slots, symbols, or the like, and/or a combination thereof.

Referring to FIG. 14 , reporting #1 is a table configured by the terminal and/or used by the terminal in order to report the A value. Reporting #2 is a table configured by the UE and/or used by the UE to report the B value.

14 , according to various embodiments, different time-stamps may be concatenated for each measurement report. For example, the A value is a relatively coarse value and may be a valid value for a relatively long time. Also, for example, the B value may be a finer value as a difference value with respect to the A value, and the valid time of the present value may be much smaller. According to various embodiments, a valid time duration of this measurement may be known through a time-stamp.

타임-스탬프의 정의What is a time-stamp?

In this case, a problem in defining the “effective time interval” may occur. For example, it may be assumed that the terminal reports 2.0 as a measurement value, but the time interval is 100 ms. In this case, the effective time interval needs to be determined based on how much error range it is within an error range based on 2.0 for 100 ms.

For example, with respect to the value of 2.0, an error of X % (X: integer greater than or equal to 0, natural number, real number) may be considered. For example, if 10% is the standard, a time interval in which 1.8 to 2.2 is maintained based on 2.0 may be reported as a time-stamp. When the UE reports 0.2 (value B) in addition to 2.0 (value A), a time interval in which 0.18 to 0.22 is maintained may be reported as a time-stamp. That is, in the case of a B value representing a relatively detailed value, the corresponding time-stamp may be much smaller than that of A .

According to various embodiments, the terminal may set/receive a reference for the reporting time-stamp from the base station/location server. According to various embodiments, the terminal may independently set/receive time-stamp criteria for the A and B values. For example, a "specific ratio" (eg, X %) may be set/indicated for the error range of the measurement value reported by the UE.

According to various embodiments, the reporting bits (quantization level) for reporting the A value may be different from the reporting bits (quantization level) for reporting the B value. According to various embodiments, the UE may be configured with a reporting table for reporting the value A and the reporting table for reporting the value B having different quantization levels. According to various embodiments, the quantization level of each of the reporting table for reporting the A value and the reporting table for reporting the B value may be different.

According to various embodiments, the fact that the quantization level is different may be related to the fact that the number of sections dividing the same reporting value range is different. For example, both the report value range and the number of sections dividing the report value range may be different.

According to various embodiments, the report table may be a table in which a measurement value to be reported by the terminal is quantized, and an index is assigned for each quantization section. According to various embodiments, the terminal may inform its own measurement value by reporting a specific index.

An example of a report table will be described. Hereinafter, a report table for RSTD reporting will be described, but a report table for reporting measurement values related to other positioning, such as a report on UE reception-transmission time difference measurement, may be separately defined/set for each measurement value.

For example, with respect to the high-resolution quantization table described above, the report range for DL RSTD measurement is

from

from to

It can be defined as the resolution step of .

E.g,

can be

E.g,

class

For RSTD measurement, one or more PRS resources configured in both the reference cell or adjacent cells are included in FR2, or one or more PRS resources configured in one or more of the reference cell or adjacent cells are included in FR1. It may vary, and at the same time, k may have to be greater than or equal to the value set by timingReportingGranularityFactor .

For example, it may be defined/set in a report table that specifies measurement report mapping according to each k value.

For example, an example of a report table may be defined as shown in Table 7. For example, the report table of Table 7 is for a report mapping for RSTD measurement report when k=0, and may be an example of the above-described high-resolution quantization table.

For example, referring to Table 7, the measured quantity value may be divided according to a preset range, and a different reported quantity value is given/corresponding to each divided range. can be For example, the measured quantity value may be quantized accordingly, and thus the resolution may be Tc (k=0).

According to various embodiments, the reporting resolution/overhead for reporting the A value and the B value may be set differently in the time-domain.

For example, the UE may independently set/receive a reporting periodicity for reporting the A value and the B value. For example, the setting/instruction may be set/instructed from a base station/location server. For example, the reporting period for the value A may be set to be relatively long, and the reporting period for the value B may be set to be relatively short. For example, the terminal may be set/instructed from the base station/location server to report the A value once and then report the B value K1 (>0) times in a specific period. And/or, the terminal may be set/instructed from the base station/location server to report K2 (>0) times with respect to the A value and the B value at a specific period.

As mentioned in the description of the various embodiments described above, the B value reported by the terminal reports A+B based on the A value, but the B value may be considered as an accumulated value. For example, the terminal reports the value of A, and then at the time of L positioning measurement report

It can be assumed to report values. This can be expressed by Equation (7).

[Equation 7]

According to various embodiments, the terminal is the L-th

When reporting

Based on , it is possible to report the obtained positioning measurement change. As such, when the terminal reports a change in location with an accumulated value, when the location server/base station does not properly receive the previously reported measurement report information, the terminal location measured/calculated using the measurement report reported later is accurate Although it may not be, there is an advantage in that the location of the UE can be continuously reported using a small reporting overhead.

On the other hand, if the A value is not reported correctly, the change value of the positioning measurement reported by the terminal later is

Reporting may not be meaningful. As a method for supplementing this, according to various embodiments, the terminal may receive a confirmation signal that the positioning measurement reported by the terminal has been correctly reported, and thereafter, B and/or

It can be set/instructed from the network to report a value.

제안#1-2 : reporting resource/channelProposal #1-2: reporting resource/channel

According to various embodiments, the A value and B/

(B and/or

), the reporting overhead and time-domain resolution corresponding to each value may be significantly different. For example, B/

Since the value means a positioning measurement difference value based on the A value, the overhead is small, but the UE may need to frequently report to the network.

According to various embodiments, the A value and B/

Reliability and/or reporting resource may be set differently for each value.

For example, the terminal may be configured/instructed to report the value A to the base station/location server via PUSCH, and may be configured to report the value B to the base station/location server via PUCCH. For example, since the value of A has a relatively large reporting overhead, it may be configured/instructed to be transmitted over the PUSCH through aperiodic reporting (DCI triggering). For example, B/ corresponding to the difference value based on the previously reported value.

The UE reporting the value may be configured/instructed to report through the PUCCH in a semi-static/periodic report type. As mentioned earlier

Since the value is an accumulated value, if the data reported by the terminal is lost, the location of the terminal cannot be accurately determined. Therefore, it may be appropriate to report through the relatively high reliability PUCCH.

According to various embodiments, in consideration of the reporting period and reliability of the A and B values, the terminal transmits the A value to the network as an RRC message, and the B/

The value can be sent to the network as a MAC message. For example, since the B value is a relative value to the A value, if the A value reported by the terminal is lost, even if the B value is accurately reported, it may be difficult to determine the location of the terminal. Accordingly, according to various embodiments, the A value and the B value may be transmitted through signals and/or channels having different reliability and/or latency characteristics in consideration of reliability and/or latency.

And/or, according to various embodiments, the UE transmits the A value to the network through MAC-CE and/or RRC signaling, and B/

The value may be transmitted through PUCCH / Uplink Control Information (UCI). MAC-CE is more reliable than UCI because it supports a hybrid automatic request (HARQ) process, but a relatively longer latency than UCI may be required. Also, during retransmission, the reported measurement information may be information that is no longer valid due to the mobility of the terminal. On the other hand, although UCI has relatively low reliability, it has an advantage that it can be transmitted with low latency.

Proposal #1 according to various embodiments relates to an operation of a terminal reporting positioning measurement. In the operation of the terminal of this proposal #1, which reports a value of A, which is a relatively coarse value, and a value of B with a finer granularity/value, the terminal measures/calculates its own location rather than reporting the positioning measurement. It can be extended/applied/applied even when the location information itself is reported to the location server/base station.

According to various embodiments, the reporting of the A value and the B value may be used for a two-stage positioning measurement and/or a two-step positioning measurement.

For example, the value of A may be a measurement result for a PRS resource and/or resource set set/instructed to be measured by the UE in the first step, and the value of B is in the second step It may be a measurement result for the PRS resource and/or resource set set/indicated for the UE to measure.

For example, the value of A and the value of B may be independent of each other and/or the value of B may be reported in the form of an offset of the value of A. For example, resolution and/or granularity of the measurement results of A and B may be different.

According to various embodiments, when the UE reports the measurement results A and B, the UE transmits information (eg, index) on a timing error group used for reception together, or Information on PRS resources and/or resource sets (eg, resource ID, resource set ID) may be included in each measurement report and transmitted. For example, the resolution and/or granularity for each measurement result may be predefined, or the LMF may dynamically set/instruct the UE and/or the base station. And/or, according to various embodiments, when the terminal reports B, whether it is a measurement result value based on the measurement of a specific PRS resource and/or resource set of A may include and transmit the factor.

Proposal Proposal

According to various embodiments, the terminal reports some or all of its (x, y, z) coordinates/positions to the location server/base station, and thereafter, the terminal position change amount ((x, y, z) coordinates/position Only some or all of them) can be reported to the location server/base station. According to various embodiments, the reporting overhead/resolution used when the terminal reports its location information and the reporting overhead/resolution used when only reporting the location change afterward may be different from each other, and each independently Instruction/configuration can be received from server/base station.

제안 : Reporting information Suggestion: Reporting information

According to various embodiments, when the terminal reports the location measurement to the location server/base station, the location server/base station may report additional information that can be used when measuring the location of the terminal. For example, the terminal may inform that a specific coordinate (eg, z-axis) among its location coordinates (x, y, z) and/or a part of location information is the same as a specific time in the past. For example, the reference of the "past specific time point" may be a time point at which the terminal most recently reported location information and/or location measurement. and/or, for example, the terminal may report the "past specific time point" to the location server/base station. And/or, for example, the terminal may inform the relationship between the y-axis and the x-axis on the moving path because the z-axis is fixed and the moving path is constant. For example, the terminal may report that it is moving equally along the y-axis by the amount it moves on the x-axis based on relative/absolute coordinates. That is, the terminal may report to the location server/base station that it is moving and/or moved along the y=x axis.

For example, it may be assumed that the height of the terminal is constant and only the x-axis and/or the y-axis is changed on a two-dimensional plane. According to various embodiments, since a specific axis is fixed rather than finding the location of the terminal in 3-dimension using an algorithm such as LS (Least Square), estimation error can be reduced. can And/or, for example, it may be assumed that the height (z-axis) and the x-axis of the terminal in a factory are fixed. In addition, if there is a correlation between the x-axis and the y-axis in the mobility of the terminal, such as y = x, for example, when measuring the position of the terminal with a positioning algorithm using this, variables can be reduced and consequently the effect of reducing the error can be obtained

According to various embodiments, the terminal may measure/recognize a change in its position for a certain period of time after a specific point in time through the mounted speed sensor, acceleration sensor, barometric pressure sensor, and the like. Considering that many smart phones currently being used by many users are equipped with various sensors, it is difficult to see the assumption of the above terminal operation as unrealistic.

As a more specific example, 1 bit is allocated to each of the (x, y, z) axes, and if it is "0" (or "1"), the position has changed compared to the previous time point, and "1" (or "0") This can tell you that nothing has changed.

According to various embodiments, when the terminal reports location information, only some information among (x, y, z) coordinate information may be reported to the location server/base station. For example, it may be assumed that the position (x, y) of the terminal on the two-dimensional coordinates does not change and only the z-axis does not change when compared with the previous specific time point. According to various embodiments, the location server can sufficiently determine the location of the terminal even if the terminal reports only the location change on the z-axis to the location server based on the location of the previous point in time, and the terminal reports unnecessary overlapping information no need to do

제안 : UE-request for reporting configuration Proposal: UE-request for reporting configuration

According to various embodiments, the terminal reports accuracy/reporting granularity/report for its preferred positioning measurement (RSTD, UE RX-TX time difference, RSRP, etc.) to the base station/location server A quantization resolution (reporting quantization resolution)/number of reporting times within a unit time may be requested/recommended/reported.

For example, when the UE reports RSTD/UE RX-TX time difference measurement, it may recommend/report its preferred timing measurement reporting accuracy to the base station/location server. For example, the operation of the UE to recommend/report timing measurement reporting accuracy may be viewed as adjusting the reporting bit/overhead by adjusting the reporting resolution.

According to various embodiments, when the range in which the timing measurement is reported is [0, A] (A>0), the values from 0 to A are quantized to K1/K2/K3 bits, and the terminal adaptively sets the quantization level. It can be selected or instructed/configured from the network. According to various embodiments, it is possible to inform the network of the quantization level preferred by the terminal before receiving an instruction/configuration from the network.

As another example, the UE may recommend/request/report to the base station/location server a time interval for reporting the positioning measurement (the number of times the positioning measurement is reported during a specific time interval, etc.).

And/or, according to various embodiments, it may be considered to simultaneously perform the first and second examples. For example, the UE recommends/reports to the network how often to report (or want to report) the positioning measurement and how much reporting resolution/bit/overhead to use when reporting the positioning measurement once. can These technical properties may be usefully used in consideration of the UE's mobility and/or data traffic to be transmitted through uplink.

For example, when the terminal moves fairly quickly, even if the quantization level is high (high resolution) and many bits are used to provide high positioning accuracy of tens of centimeters level, the information reported by the terminal is effective because the time is short. At the time of using one piece of information, it may not be valid information. And/or, the effective time interval may be short, so it may have to be reported too often, and thus the reporting overhead of the UE may increase excessively.

As another example, a relatively slowly moving terminal may be considered. When such a terminal frequently reports the positioning measurement to the location server, it can be seen that uplink resources are wasted.

According to various embodiments, the terminal may determine its own mobility through an acceleration/velocity sensor, etc. mounted on it, and inform the network of this in consideration of the time it is necessary to update its location change information.

제안 : event-triggered reporting/on-demand positioning measurement/location reportingProposal: event-triggered reporting/on-demand positioning measurement/location reporting

According to various embodiments, the terminal may request a location measurement report in order to report location measurement and/or its location to a base station/location server when a location change greater than or equal to a specific threshold occurs. The above operation can be seen as a request for a time-frequency resource for the location measurement report by the terminal.

According to various embodiments, upon requesting the report, the UE may recommend/request the preferred reporting resolution (and/or reporting accuracy/report granulation/report quantization resolution/number of reporting times within a unit time) to the network. According to various embodiments, when a location change of more than a specific threshold occurs, the terminal may measure positioning and/or report its location to the base station/location server.

According to various embodiments, the “change in position above a specific threshold” may be considered as a specific “event occurrence”. According to various embodiments, event-triggered location measurement and/or location reporting may be supported. According to various embodiments, for the operation of the terminal, the base station may configure the resource (PUSCH and/or PUCCH) for the terminal's report at regular time intervals for the location measurement report to the terminal.

According to various embodiments, the location server/base station may set the terminal operation to "on/off" in the terminal (for even-triggered/event-based positioning measurement and/or UE's location estimation reporting). For example, if the terminal operation is set to "on", the terminal may report its location and/or positioning measurement when a specific event occurs. For example, a specific bit field (eg, 1-bit field) may be introduced for on/off indication of terminal operation, and when the bit field is a first value (eg, 0 or 1), terminal operation This is mapped to being “on” (activated), and when the bit field is a second value (eg, 1 or 0), it may be mapped to being “off” (deactivated) of the terminal operation.

According to various embodiments, the location server/base station may set for a "specific event" in the terminal. For example, if the terminal measures the location of the terminal and/or the terminal's own absolute/relative position change after a specific time point is "X %" and/or "X meters/centimeter" or more, the terminal measures the location and/or the location can be set to report. For example, the location server/base station may set the value of X (a natural number, an integer, a real number).

Proposal : Reporting based on Linear combinationProposal : Reporting based on Linear combination

According to various embodiments, the terminal may be configured/instructed to report the positioning measurement in the form of a linear combination and/or a weighted average value from the base station/location server.

For example, the positioning measurement that the terminal reports to the base station/location server at a specific time point (eg, the current time point) may be referred to as measurement(K). For example, measurement(K) may mean a K-th reported positioning measurement. According to various embodiments, the terminal reports a linear combination value of K-1 previously reported positioning measurements and the K-th positioning measurements to be reported at the current time in order to indicate positioning measurements that cannot be expressed in a report table. can This can be expressed by Equation (8).

[Equation 8]

In Equation 8,

The value may mean a positioning measurement that the terminal wants to report to the base station/location server. For example, the UE uses a specific RS (eg, PRS, SSB, CSI-RS, etc.) to utilize for UE positioning such as RSTD, UE Rx-Tx time difference, RSRP, SINR, SNR, etc. Measurement obtained using can be

In Equation 8,

may be a real number greater than 0 and less than 1. For example, said

The value may be reported by the terminal to the base station/location server. For example, the K value may be set/instructed by the base station/location server to the terminal, or the terminal may determine itself and report it to the base station/location server. and/or, for example, the base station/location server sets the maximum value (K_max) for the K value in the terminal, the terminal uses/selects a value smaller than the set K_max value, and sets the selected value to the base station/location server can be reported to For example, said

To report the value, the terminal

A mapping table for values and reported values may be set, or a predefined/predefined table may be used.

According to various embodiments, the UE may report the K-th RSTD value as a linear combination value for K-1 previously reported positioning measurements, instead of directly reporting the positioning measurements. The K-th RSTD value may mean an RSTD value reported at the current time. In this case, the terminal in Equation 8

Only the value needs to be reported to the location server/base station.
