Description

[Technical Field]

[0001] The present disclosure relates to a terminal, a wireless communication method and an apparatus in a next-generation mobile communication system. [Background technology]

[0002] In Universal Mobile Telecommunications System (UMTS) networks, Long Term Evolution (LTE) has been specified with the aim of achieving higher data rates and lower latency (Non-Patent Document 1). Also, LTE-Advanced (3GPP Rel. 10-14) has been specified with the aim of achieving higher capacity and more advanced features than LTE (Third Generation Partnership Project (3GPP (registered trademark)) Release (Rel.) 8, 9).

[0003] Successor systems to LTE (e.g., 5th generation mobile communication system (5G), 5G+ (plus), 6th generation mobile communication system (6G), New Radio (NR), 3GPP Rel. 15 or later) are also being considered. [Prior art documents] [Non-patent literature]

[0004] [Non-Patent Document 1] 3GPP TS 36.300 V8.12.0 “Evolved Universal Terrestrial Radio Access (E-UTRA) and Evolved Universal Terrestrial Radio Access Network (E-UTRAN); Overall description; Stage 2 (Release 8)”, April 2010 Summary of the Invention [Problem to be solved by the invention]

[0005] In future wireless communication systems (Rel. 19 and later), it is being considered to perform positioning (AI / ML-based positioning) of terminals (which may also be called user terminals or user equipment (UE)) using Artificial Intelligence / Machine Learning (AI / ML) technology.

[0006] Regarding the AI / ML-based positioning, it is considered that Positioning Reference Unit (PRU) measurements and corresponding PRU positions are transmitted from the LMF to the target UE for monitoring metric calculation using the Rel. 18 Assistance Data Transfer Framework.

[0007] The PRU measurements used for the above-mentioned monitoring metric calculations must be PRU measurements that are compatible with the AI ​​model that the UE can use. However, the Rel. 18 assistance data transfer framework does not guarantee that the UE can receive the desired PRU measurements.

[0008] If a UE cannot receive the desired PRU measurements, it may not be able to properly perform monitoring based on the PRU measurements. As a result, it may not be able to select an appropriate AI model, which may have a negative impact on positioning quality. In this case, it may not be possible to achieve high-accuracy, high-efficiency, and low-complexity positioning using AI / ML technologies, which may hinder improvements in communication quality and communication throughput.

[0009] Therefore, one of the objects of the present disclosure is to provide a terminal, a wireless communication method, and an apparatus that can suitably achieve positioning with high accuracy, high efficiency, and low complexity. [Means for solving the problem]

[0010] A terminal according to one embodiment of the present disclosure has a transmitting unit that transmits information requesting a measurement format of a Positioning Reference Unit (PRU) to a device other than the PRU, and a control unit that determines whether the measurement received from the other device conforms to the format. [Effects of the Invention]

[0013] (Positioning technology) Fingerprinting localization, which estimates the location of wireless devices by utilizing the propagation characteristics of wireless signals, is widely used in both Line of Sight (LOS) and Non-Line of Sight (NLOS) scenarios.

[0014] In this disclosure, LOS may mean that the UE and the base station are in an environment where they can see each other (or there are no obstructions), and NLOS may mean that the UE and the base station are not in an environment where they can see each other (or there are obstructions).

[0015] In fingerprinting localization, the location of the UE may be estimated from fingerprints of multiple transmission paths (multipaths) of the UE based on a database or the like.

[0016] The multipath information may be, for example, information relating to the Angle of Arrival (AoA) / Angle of Departure (AoD) of the signal for optimal / candidate transmission paths.

[0017] In the present disclosure, the information on AoA may include, for example, information on at least one of azimuth angles of arrival and zenith angles of arrival, and the information on AoD may include, for example, information on at least one of azimuth angles of departure and zenith angles of departure.

[0018] 3GPP Rel.16 NR supports the following positioning technologies: DL / UL Time Difference Of Arrival (TDOA) based positioning, Positioning based on angles (DL AoD / UL AoA), Multi-Round Trip Time (RTT) based positioning, Enhanced Cell ID (E-CID) based positioning.

[0019] In positioning based on DL / UL TDOA, for example, assume that multiple base stations (TRP#0-#2) are located around the UE. In this positioning method, the location of the UE is estimated (measured) using a measurement value of the Reference Signal Time Difference (RSTD). For example, the RSTD (Time Difference Between RSTDs) for two specific base stations (TRP#i, #j (i and j are integers)) is i -T j ) for some value (k i,j ) to draw the hyperbola H i,j The intersection of multiple such hyperbolas (H in this example) 0,1、 H 1,2、 H 2,0 The location of the UE may be estimated by using the reference signal received power (RSRP) of the reference signal.

[0020] In a DL AoD / UL AoA based positioning method, the UE location is estimated using DL AoD measurements (e.g., θ or φ) or UL AoA measurements (e.g., θ or φ). The UE location may also be estimated using RSRP.

[0021] In a multi-RTT-based positioning method, the location of a UE is estimated using multiple RTTs calculated from the Tx / Rx time difference of a reference signal (and additionally RSRP, Reference Signal Received Quality (RSRQ), etc.). For example, geometric circles based on the RTTs can be drawn with each base station at its center. The intersection of these multiple circles may be estimated as the location of the UE.

[0022] E-CID based positioning / In this positioning method, the UE's location is estimated based on the geometric location of the serving cell / neighbor cells and additional measurements (Tx-Rx time difference, RSRP, RSRQ, etc.).

[0023] The positioning in the DL (DL TDOA, DL AoD) described above may be performed by the UE side or the LMF side. For example, in UE-based positioning, the UE may calculate the UE position based on various measurement results of the UE and assistance information from the LMF. In addition, in UE-assisted positioning, the UE may report various measurement results to the LMF, and the LMF may calculate the UE position. The assistance information may be information for assisting in estimating the UE's position.

[0024] The above-mentioned positioning in UL (UL TDOA, UL AoA) may be performed on the LMF side. In this case, the base station may report various measurement results to the LMF, and the LMF may calculate the position of the UE.

[0025] The above-mentioned DL and UL (multi-RTT, E-CID) positioning may be performed on the LMF side. In this case, the UE / base station may report various measurement results to the LMF, and the LMF may calculate the UE's position.

[0026] Furthermore, in 3GPP Rel. 17, a positioning method using assistance information is proposed for the purpose of further improving positioning accuracy. The assistance information may be transmitted between the UE, the base station, and the LMF as measurement information for the above-mentioned DL / UL-TDOA, DL-AoD / UL-AoA, multi-RTT, and E-CID.

[0027] The assistance information may include information regarding at least one of the following: Timing Error Group (TEG). Path-specific RSRP (Reference Signal Received Path Power (RSRPP)). Expected angle. Adjacent beam information. ·TRP antenna / beam information. LOS / NLOS indicator. -Additional path reporting.

[0028] The TEG may indicate one or more Positioning Reference Signal (PRS) resources whose transmit / receive timing errors (Rx / Tx timing errors) are within a certain margin.

[0029] The RSRPP may indicate the measurement result of the RSRP on the first pass.

[0030] In UL positioning, the assistance information regarding the expected angle may indicate an expected UL-AoA / ZoA. The assistance information may be transmitted from the LMF to the base station. The assistance information may also support at least one of UL TDOA, UL AoA, and multi-RTT positioning.

[0031] In DL positioning, the assistance information regarding the expected angle may include information regarding the expected DL-AoA / ZoA or DL-AoD / ZoD. The assistance information may be transmitted to the UE from the LMF. The assistance information may also support at least one of DL TDOA, DL AoA, and multi-RTT positioning. This improves the accuracy of angle-based UE positioning and enables optimization of Rx beamforming for the UE or base station.

[0032] The assistance information regarding the predicted angles may include, in addition to the information on the values ​​of AoA / ZoA / AoD / ZoD themselves as described above, information indicating the uncertainty range of these values.

[0033] As additional beam information, the neighboring beam information may include information about a subset of DL-PRS resources for the purpose of prioritizing DL-AoD reports (Option 1) or the boresight direction of each DL-PRS resource (Option 2), allowing for optimization of UE Rx beam sweeping and DL-AoD measurements.

[0034] As additional beam information, the assistance information may also include PRS beam pattern information, which may include information regarding the relative power between DL-PRS resources for each angle for each TRP.

[0035] The LOS / NLOS indicator may indicate information regarding Line Of Sight (LOS) / Non-Line Of Sight (NLOS).

[0036] In addition, in order to improve the UE positioning delay, pre-configured measurement gaps (MG), activation of MG via lower layers, MG-less location, PRS Rx / Tx in RRC_INACTIVE state, or on-demand PRS may be configured for the UE (or may be used by the UE).

[0037] In 3GPP Rel.17 NR, it is agreed that the UE measures / reports the RSRP of neighboring beams to improve the accuracy of UE location estimation. For example, in the UE-assisted DL-AoD positioning method, the LMF can indicate at least one of the following options 1 to 2 in the assistance information:

[0038] Option 1: Subset of PRS resources for DL-AOD reporting prioritization. The subset may be configured for each PRS resource depending on the UE capabilities. The UE may include requested PRS measurements for a subset of PRSs in the DL-AoD additional measurements if requested PRS measurements are reported for the associated PRS. The requested PRS measurements may be DL PRS RSRP / path PRS RSRP. The UE may report PRS measurements only for a subset of PRS resources. Note that the associated subset of a PRS resource may be in the same / different PRS resource set as the PRS resource. · Option 2: Information about the boresight direction to be configured for each PRS resource depending on the UE capabilities.

[0039] In 3GPP Rel.16 NR, it is agreed that the expected RSTD and its uncertainty range will be indicated to the UE from the LMF. Furthermore, in Rel.17, it is agreed that the expected angle and its uncertainty range will be indicated to the UE from the LMF to reduce errors and complexity in AoA / AoD measurements.

[0040] 3GPP Rel. 17 NR is considering the introduction of a Positioning Reference Unit (PRU) for positioning. The PRU is being discussed as a reference device with a known location to mitigate transmission and reception timing errors of the UE / gNB. In this disclosure, PRU may be interpreted as UE / gNB / TRP (transmission reception point) / TP (transmission point).

[0041] For example, a PRU may support at least one of the following: ·Measure DL PRS and report related measurements (e.g., RSTD / Transmit / Receive Time Difference / RSRP) to the LMF. Transmitting SRS and enabling the TRP to measure and report measurements related to the reference device (e.g., Relative Time of Arrival (RTOA) / AOA) to the LMF. · Operation, measurement and various parameters (parameters related to transmit / receive timing delays, AoD and AOA enhancements, and calibration of measurements). If the LMF does not have the position coordinate information, report the position coordinate information of the reference device to the LMF. The reference device with a known location is a UE / gNB. · The accuracy with which the position of the reference device can be known.

[0042] (AI / ML-based positioning) Regarding future wireless communication technologies, the use of AI technologies such as machine learning (ML) for network / device control and management is being considered.

[0043] There are two use cases for AI / ML-based positioning: Direct AI / ML positioning. AI / ML assisted positioning.

[0044] Direct AI / ML positioning outputs, for example, UE positioning (UE location), while AI / ML assisted positioning outputs, for example, intermediate features, which may be input back into the AI / ML model.

[0045] Example outputs of the AI / ML assisted positioning described above may include at least one of the following: LOS / NLOS identification (LOS / NLOS probability), ToA (PRS / SRS arrival time), Rx-Tx (transmit / receive) time difference, AoA / AoD, Number of waves, Rx-Tx (transmit / receive) phase difference (Rel.18 phase measurement), DL RSTD / UL TDOA, ·DL-PRS / UL-SRS, RSRPs / RSRPPs, Likelihood of the above numbers (e.g., ToA probability).

[0046] Rel. 18 positioning introduces sidelink positioning based on the Sidelink Positioning Protocol (SLPP). For example, SL-RTT, SL-AoA, SL-TDOA, and SL-TOA are introduced. For example, the sidelink reference signal used for position calculation is called SL-PRS. Measurements based on SL-PRS may include at least one of the following: SL PRS-RSRP, SL PRS-RSRPP, SL RTOA, SL AoA, sidelink receive-transmit (Rx-Tx) time difference, SL RSTD, SL PRS-RSSI, SL PRS-channel occupancy ratio (CR), and SL PRS-channel busy ratio (CBR). Furthermore, measurements related to the carrier phase positioning method may include at least one of UL / DL reference signal carrier phase (RSCP) and DL reference signal carrier phase difference (RSCPD).

[0047] (Use case of AI-based positioning) Typical use cases for AI / ML-based positioning can be classified as follows, depending on which entity's (or which entity's) model is used and whether measurement results of either DL or UL signals are used for location prediction:

[0048] 1A to 1C are diagrams showing variations of positioning using DL signals, and FIGS. 2A and 2B are diagrams showing variations of positioning using UL signals.

[0049] Case 1 (Fig. 1A): UE-based positioning using a UE-side model (direct AI / ML positioning or AI / ML-assisted positioning). Case 2a (Fig. 1B): UE-assisted / LMF-based positioning using a UE-side model (AI / ML-assisted positioning). Case 2b (Fig. 1C): UE-assisted / LMF-based positioning using LMF-side model (direct AI / ML positioning). Case 3a (Fig. 2A): NG-RAN node-assisted positioning (AI / ML-assisted positioning) using gNB-side model. Case 3b (Fig. 2B): NG-RAN node-assisted positioning (direct AI / ML positioning) using LMF-side model.

[0050] <Case 1> Case 1 is an example of positioning using a UE-side model and DL signals / channels (see Figure 1A). In Case 1, the UE receives (required) assistance information related to positioning (location prediction) from the NW (gNB / LMF). The UE-side model calculates (measures / predicts) the UE location or intermediate value based on the assistance information and DL signals / channels from the NW. The UE transmits the UE location or intermediate value to the NW (LMF).

[0051] <Case 2a> Case 2a is an example of positioning using a UE-side model and DL signals / channels (see Figure 1B). In Case 2a, the UE receives (required) assistance information related to positioning (location prediction) from the NW (gNB / LMF). The UE-side model calculates (measures / predicts) intermediate values ​​based on the assistance information and DL signals / channels from the NW. The UE transmits the intermediate values ​​to the NW (LMF).

[0052] <Case 2b> Case 2b is an example of positioning using the LMF-side model and DL signals / channels (see Figure 1C). In Case 2b, the UE transmits measurement results of DL signals (specific signals / channels (e.g., RS)) from the NW to the NW (gNB / LMF). The UE also receives instructions from the NW to collect (required) data related to positioning (location prediction). The LMF-side model calculates (measures / predicts) the UE location based on the measurement results of the DL signals.

[0053] <Case 3a> Case 3a is an example of positioning using a gNB-side model and UL signals / channels (see Figure 2A). In Case 3a, the gNB receives (required) assistance information related to positioning (location prediction) from the LMF. The gNB-side model calculates (measures / predicts) intermediate values ​​based on the assistance information and the UL signals / channels from the UE. The gNB transmits the intermediate values ​​to the LMF.

[0054] <Case 3b> Case 3b is an example of positioning using the LMF-side model and UL signals / channels (see Figure 2B). In Case 3b, the gNB transmits measurement results of UL signals (specific signals / channels (e.g., RS)) from the UE to the LMF. The gNB also receives (required) assistance information related to positioning (location prediction) from the LMF. The LMF-side model calculates (measures / predicts) the UE location based on the measurement results of the UL signals.

[0055] In the present disclosure, the intermediate value may correspond to a value / information that can be used to determine location information (for example, the arrival time difference of multiple signals (RS), or the RTT of a certain signal (RS)).

[0056] (Sample-based positioning / Path-based positioning) In AI / ML-based positioning in future wireless communication systems (e.g., Rel. 19 and later), the introduction of sample-based measurements and path-based measurements as measurements for input to the model is being considered.

[0057] <Sample-based measurement> The sample-based measurement may be a measurement consisting of Nt' samples of an estimated channel response in the time domain, where the Nt' samples may be selected from the Nt samples.

[0058] Timing information for Nt' samples may be measured / reported with timing measurement granularity T.

[0059] T may be determined based on the timing reporting granularity factor k and the basic time unit Tc in NR, where T=2 k *Can also be Tc.

[0060] The corresponding measurements (eg, power) may correspond to measurements of the reported Nt' samples.

[0061] The values ​​of Nt, Nt' and k may be determined based on notification from the LMF to the base station / UE using higher layer signaling (eg, NRPPa / LPP).

[0062] The timing information may be specified relative to a reference time.

[0063] The timing reporting granularity factor k may be signaled, for example, using the upper layer parameter timingReportingGranularityFactor.

[0064] A negative value of T may mean that the corresponding particular path is earlier in time (past) than the detected path at the reference (time).

[0065] 3 is a diagram showing an example of sample-based measurement, in which Nt' samples are selected from Nt samples and measured.

[0066] <Path-based measurement> Path-based measurements may be measurements that include measurement reports in existing specifications (e.g., up to Rel. 18). In other words, path-based measurements may correspond to measurements in existing specifications (e.g., up to Rel. 18).

[0067] Timing information related to path-based measurements may be measured / reported with timing measurement granularity T.

[0068] T may be determined based at least on the timing reporting granularity factor k. As noted above, T=2 k *Tc. Note that k in sample-based measurement and k in path-based measurement may be different.

[0069] The definition of the path may be determined based on the implementation of the UE / NW.

[0070] The recommended value of k may be notified from the LMF to the base station / UE using higher layer signaling (e.g., NRPPa / LPP).

[0071] (analysis) Regarding the model performance monitoring in Case 1, it is considered that the UE (target UE) performs the monitoring metric calculation. In this case, it is considered that the UE transmits the monitoring outcome to the LMF. It is also considered that the AI ​​model to be used, the positioning method, etc. are determined based on the monitoring outcome.

[0072] For the above monitoring metric calculation, it is considered that the PRU measurements and corresponding PRU locations are transmitted from the LMF to the target UE using the Rel.18 assistance data transfer framework.

[0073] 4A and 4B illustrate an example of an assistance data transfer framework in Rel. 18. As shown in FIG. 4A, a UE sends an LPP Request Assistance Data message (RequestAssistanceData message) to an LMF requesting assistance data, for example, for DL-TDOA positioning. In response, the LMF sends an LPP Provide Assistance Data message (ProvideAssistanceData message) containing the requested assistance data to the UE. FIG. 4B also illustrates an example of assistance data that may be transferred from an LMF to a UE. As described above, PRU measurements and corresponding PRU locations may be included in the assistance data. The assistance data may be used in the UE for UE-based or UE-assisted positioning.

[0074] Figure 5 is a diagram showing an example of assistance data request information in Rel. 18. This example is written using Abstract Syntax Notation One (ASN.1) notation (the same applies to subsequent similar drawings). Note that this is merely an example and may not be a complete description, but the intent of the description will be understandable to those skilled in the art.

[0075] In the present disclosure, the names of RRC information elements, RRC parameters, etc. are not limited to the names shown, and may be given a suffix indicating that they are introduced in a specific resource (e.g., "_r19", "-r19", etc.). The suffix may not be given, or another word may be given.

[0076] The request information is an information element for requesting DL-TDOA positioning assistance data (NR-DL-TDOA-RequestAssistanceData information element) used by the target device (target UE) to request assistance data from the location server (LMF). The NR-DL-TDOA-RequestAssistanceData information element may be included in an LPP Request Assistance Data message.

[0077] The nr-PosCalcAssistanceRequest-r17 field in this information element indicates the requested position calculation assistance data. This field is represented as a bit string, and a value of '1' in each bit position indicates that specific assistance data is requested. Bit 6 (pruInfo-r18) of this field indicates whether the nr-PRU-DL-Info field in the NR-PositionCalculationAssistance information element is required. The nr-PRU-DL-Info field indicates the information element (NR-PRU-DL-Info information element) used by the location server (LMF) to provide measurement / additional information reported by the PRU.

[0078] The NR-PositionCalculationAssistance information element may correspond to, for example, position calculation assistance data for UE-based positioning. This information element may be included in an information element for providing assistance data for DL-TDOA positioning (NR-DL-TDOA-ProvideAssistanceData information element) used by a location server (LMF) to provide assistance data. The NR-DL-TDOA-ProvideAssistanceData information element may be included in an LPP Provide Assistance Data message.

[0079] FIG. 6 is a diagram showing an example of PRU measurement information in Rel. 18. This PRU measurement information is the NR-PRU-DL-Info information element described above. This information element may include, for example, the NR-DL-TDOA-SignalMeasurementInformation information element used to provide DL-TDOA measurements. For simplicity, some fields / information elements are omitted in this example ("==omit==" indicates that the surrounding fields / information elements are omitted; the same applies to subsequent similar drawings).

[0080] According to the Rel.18 assistance data transfer framework described above, the UE can obtain PRU measurements from the LMF.

[0081] For future wireless communication systems (e.g., Rel. 19 and later), the PRU measurements used for the above-mentioned monitoring metric calculations are required to be PRU measurements that correspond to the AI ​​models available to the UE. However, the above-mentioned Rel. 18 assistance data transfer framework does not guarantee that the UE can receive the desired PRU measurements.

[0082] If a UE cannot receive the desired PRU measurements, it may not be able to properly perform monitoring based on the PRU measurements. As a result, it may not be able to select an appropriate AI model, which may have a negative impact on positioning quality. In this case, it may not be possible to achieve high-accuracy, high-efficiency, and low-complexity positioning using AI / ML technologies, which may hinder improvements in communication quality and communication throughput.

[0083] Therefore, the present inventors have conceived a method that allows a UE to efficiently receive desired PRU measurements.

[0084] Hereinafter, embodiments according to the present disclosure will be described in detail with reference to the drawings. Wireless communication methods according to the embodiments may be applied independently or in combination.

[0110] In the present disclosure, an LPP message may be interchangeable with any message exchanged between a UE and an LMF. Also, in the present disclosure, an NRPPa message may be interchangeable with any message exchanged between a gNB and an LMF.

[0111] (Wireless communication method) In this disclosure, positioning is mainly exemplified as a use case of an AI model. Positioning in the following embodiments may refer to AI / ML-based positioning. The embodiments of the present disclosure are applicable to any positioning use case (DL positioning / UL positioning, UE / gNB / LMF-based positioning, and at least one of the above cases (Cases 1 to 3b)). The embodiments of the present disclosure may be applied to other use cases by rephrasing use-case-specific (e.g., positioning-specific) terms.

[0112] The UE / NW (base station (gNB) / LMF) may perform positioning and various related operations (measurement / prediction / reporting / transmission / reception) by applying the embodiments described below.

[0113] The UE / NW (base station) may receive various settings for positioning / measurement / reporting, and may report / send the corresponding prediction (positioning) results to the NW (LMF).

[0114] The NW (base station / LMF) may send various configurations for positioning / measurement / reporting to the UE / base station. The NW may also receive corresponding prediction results (reports) from the UE / base station. For example, the LMF may send an instruction to the UE / base station requesting inferred location information / intermediate values.

[0115] The UE / NW (base station / LMF) may control various operations related to positioning (transmission and reception of related information) by applying the embodiments of the present disclosure and the various provisions described above. Furthermore, the UE / NW (base station / LMF) may execute information exchange between multiple entities to realize these various operations.

[0119] FIG. 7 illustrates an example procedure for a report format request / report according to one embodiment of the present disclosure.

[0120] In step S101, the UE may request a reporting format of the PRU measurement [that it wishes to receive as Assistance Data] from the NW (e.g., LMF). The reporting format of the PRU measurement may be transmitted using a first message (e.g., LPP Request Assistance Data message). The UE may determine the reporting format suitable for the AI ​​model used for monitoring metric calculation and implement the request.

[0121] In step S102, the LMF may request a report format [of PRU measurements] from the PRU. Note that the PRU may assume that the report format [of PRU measurements] is requested from the LMF. The report format [of PRU measurements] may be transmitted using a second message (e.g., a specific LPP message). The second message may correspond to a message for requesting PRU measurements.

[0122] In step S103, the PRU may report PRU measurements. The PRU measurements may be transmitted using a third message (e.g., a specific LPP message). The PRU measurement report may or may not follow the above reporting format. The PRU measurement report may be referred to as a PRU measurement report.

[0123] In the present disclosure, measurement result and measurement may be interchangeable. In the present disclosure, PRU measurement may be interchangeable with PRU measurement / PRU position. In the present disclosure, PRU measurement and measurement may be interchangeable.

[0124] In step S104, the UE may receive PRU measurements from the network (e.g., the LMF). The PRU measurements may be reported using a fourth message (e.g., an LPP Provide Assistance Data message). The UE may be explicitly or implicitly informed (or may assume that it is informed) of the reporting format of the PRU measurements.

[0125] The notification of the report format of the PRU measurement in step S103 or S104 may be called a report format report. The report format report may be reported simultaneously with the PRU measurement, included in the third or fourth message, or transmitted in a separate message.

[0126] Note that the UE in the above procedure may be replaced with a gNB. Also, the PRU in the above procedure may be replaced with a UE / gNB other than the UE that requests the report format in step S101. When the UE / PRU is replaced with a gNB, the LPP message in the above procedure may be replaced with an NRPPa message.

[0127] In addition, at least one step in the above procedure may be omitted, for example, steps S101 to S103 may be omitted.

[0128] In the present disclosure, PRU measurements or reporting of PRU measurements may be controlled based on a reporting format, which may specify at least one of the following: Measurement type (e.g., sample-based measurement, path-based measurement), parameters [for measurement], Information about the reference signal (RS) used for the measurement.

[0129] In the present disclosure, the terms measurement type, measurement method, etc. may be read interchangeably.

[0130] The above parameter [for measurement] may correspond to, for example, Nt / Nt' / k in sample-based measurement, k / number of additional paths in path-based measurement, etc. Note that k for sample-based measurement and k for path-based measurement may be specified to different values.

[0131] The RS used for the PRU measurement may be, for example, a PRS. Information about the RS used for the measurement may include, for example, information about the time resource (timing) of the RS (for example, period, start timing), information about the frequency resource (for example, band) of the RS, etc.

[0132] In this disclosure, the reporting format may be interchangeably read as measurement type, measurement parameter, measurement characteristics, reporting characteristics, measurement format, format, [reporting / measurement] setting, etc.

[0133] First Embodiment The first embodiment relates to the request for a report format from the UE in the above step S101 and the reception of the UE's PRU measurements in the above step S104.

[0134] The UE may transmit the report format information (hereinafter also referred to as report format information, format information, etc.) in an information element for requesting Assistance Data for a specific positioning. For example, the information element may be an existing DL-TDOA Assistance Data Request information element (NR-DL-TDOA-RequestAssistanceData information element) or a new information element for requesting Assistance Data for AI / ML-based positioning. The information element may be included in the first message.

[0135] FIG. 8 is a diagram showing an example of format information included in a DL-TDOA assistance data request information element in the first embodiment.

[0136] In this example, the DL-TDOA Assistance Data Request information element includes a format information field (nr-measurementformat-r19), which may include measurement type information (nr-measurementtype-r19), parameters for sample-based measurements (nr-sample-basedmeasurementparameter-r19), parameters for path-based measurements (nr-path-basedmeasurementparameter-r19), etc.

[0137] As already mentioned, the description of the ASN.1 format in the present disclosure is an example and may not be exactly as shown (for example, the format information field in FIG. 8 may be represented by a choice type, a sequence type, or the like, instead of a bit string type). The format information may also be defined as an information element (for example, NR-MeasurementFormat-r19).

[0138] Note that nr-samplenumber, nr-reportnumber, and nr-timinggranularityfactor in nr-sample-basedmeasurementparameter-r19 may respectively indicate Nt, Nt', and k in sample-based measurement, and nr-timinggranularityfactor and nr-additionalpathnumber in nr-path-basedmeasurementparameter-r19 may respectively indicate k and the number of additional paths in path-based measurement.

[0139] FIG. 9 is a diagram illustrating an example of format information included in an information element requesting assistance data for AI / ML-based positioning in the first embodiment.

[0140] In this example, the information element (NR-DL-AI / MLbasedpositioning-RequestAssistanceData-r19) requesting assistance data for AI / ML-based positioning includes a format information field (nr-measurementformat-r19). The content of the format information may be the same as that shown in FIG.

[0141] The UE may use the format information to request a report format (e.g., at least one of the following) (in other words, the format information may indicate at least one of the following): Sample-based and / or path-based measurements; For a parameter, one value or multiple values, Priority of each parameter or combination of parameters, A combination of the above.

[0142] The parameter value may be expressed as a range.

[0143] The above priority may be used by a PRU to determine which measurement method / parameter to actually use when measurements based on multiple measurement methods / parameters are requested at the same time. For example, a PRU may perform a measurement at a certain time using a measurement method / parameter with a higher priority. Note that in this disclosure, the terms priority, priority, priority value, etc. may be interpreted as interchangeable.

[0144] In the present disclosure, the format information may be explicitly represented by a measurement method / parameter that specifies the report format, or may be implicitly represented by a specific indicator (or identifier (ID)). For example, the value of the indicator (or ID) may be associated with a specific report format [information]. This association may be predefined or pre-configured between the UE, LMF, and PRU.

[0145] The UE may assume that the LMF will receive the formatting information (or a first message containing the information) and that the LMF will return a response to the formatting information (or the first message), which may be the fourth message described above or may be included in the fourth message.

[0146] The response may include at least one of the following: · PRU measurements held by LMF, Whether the PRU measurements comply with (or correspond to) the requested reporting format; · Reporting format for PRU measurements held by LMF; · Reasons for not reporting PRU measurements according to the requested reporting format; A combination of the above.

[0147] The PRU measurements included in the response may be reported using an existing specific information element (NR-PRU-DL-Info information element) or a new information element for providing assistance data for AI / ML-based positioning. If the PRU measurements are sample-based measurements, the response may include information indicating the measurement results for each sample. If the PRU measurements are path-based measurements, the response may include information indicating the measurement results for each path.

[0148] The PRU measurements included in the response may include one or more PRU measurements held by the LMF that correspond to the requested reporting format, or may not include any PRU measurements that correspond to the requested reporting format. The PRU measurements included in the response may include one or more PRU measurements that correspond to unrequested reporting formats instead of or in addition to one or more PRU measurements that correspond to the requested reporting format. Note that the PRU measurements held by the LMF may include measurements obtained before receiving the request for a reporting format, or may include measurements obtained after receiving the request.

[0149] The response may indicate the reporting format corresponding to the PRU measurements included in the response (i.e., the reporting format actually used for the PRU measurements), allowing the UE to conveniently determine whether the PRU measurements included in the response comply with the requested reporting format.

[0150] The report format corresponding to the PRU measurement included in the response may be indicated by format information.

[0151] 10 is a diagram illustrating an example of a notification of a report format corresponding to PRU measurements in the first embodiment. In this example, the NR-PRU-DL-Info-r18 information element includes a format information field (nr-measurementformat-r19).

[0152] The report format corresponding to the PRU measurements included in the response may be restricted, for example, to report formats that use only values ​​smaller or larger than the value of a certain parameter indicated by the requested report format.

[0153] The information regarding whether the PRU measurement complies with (or corresponds to) the requested reporting format may correspond to the format information or may be represented by other information (e.g., a Boolean value) (e.g., TRUE indicates that the PRU measurement complies with the requested reporting format). In the present disclosure, the other information may also be included in (or defined as) the format information. Note that if neither the corresponding format information nor information regarding whether the PRU measurement complies with the requested reporting format is included in the response, it may be implicitly indicated that the PRU measurement complies with the requested reporting format.

[0154] The UE may determine the report format to be subsequently requested based on the report format of the PRU measurement held by the LMF contained in the response. By requesting a report format selected from the report formats of the PRU measurement held by the LMF, the UE can reliably obtain the PRU measurement held by the LMF.

[0155] The reason for not reporting the PRU measurements according to the requested reporting format may be indicated by a specific failure message, which may indicate, for example, one or a combination of the following: LMF does not have PRU measurements in accordance with the requested reporting format; The PRU does not support the measurement method specified by the requested reporting format; · The PRU does not support measurements using the parameters specified by the requested reporting format.

[0156] Regarding the reason for not reporting PRU measurements according to the requested reporting format, the response may include information that can identify which PRU does not support which reporting format (e.g., the PRU's ID, format information / specific indicators associated with the ID, etc.).

[0157] The UE may determine whether the PRU measurements included in the response comply with the requested reporting format, and if the PRU measurements included in the response comply with the requested reporting format, the UE may perform monitoring metric calculations based on the received PRU measurements.

[0158] If the PRU measurements included in the response do not conform to the requested reporting format, the UE may determine whether the reporting format of the PRU measurements corresponds to (or is applicable to) an AI model available to the UE, so that the UE can determine whether to perform monitoring metric calculations based on the received PRU measurements.

[0159] The UE may not need to transmit format information (or a first message including the information). Even in this case, the LMF may transmit information / message equivalent to the response (e.g., a message including the PRU measurement possessed by the LMF and format information corresponding to the report format of the PRU measurement) to the UE. In other words, even if the UE does not transmit format information, the UE may receive the PRU measurement associated with the format information (it may be assumed that the UE is notified of the report format corresponding to the PRU measurement).

[0160] According to the first embodiment described above, for example, the UE can request a report format from the LMF and preferably receive desired PRU measurements corresponding to the report format.

[0161] <Second embodiment> The second embodiment relates to requesting a report format from the LMF in step S102 above and receiving the LMF's PRU measurements in step S103 above.

[0162] The LMF may transmit the format information to the PRU in a specific information element. The format information may be the same as the format information requested by the UE or may be format information determined by the LMF. For example, the specific information element may be a new information element (e.g., NR-ReportingformatRequest-r19 information element) for requesting a reporting format. The information element may be included in the second message.

[0163] 11 is a diagram illustrating an example of format information included in an information element requesting a reporting format in the second embodiment. In this example, the NR-ReportingformatRequest-r19 information element includes a format information field (nr-measurementformat-r19).

[0164] The LMF may use the format information to request a report format (e.g., at least one of the following) (in other words, the format information may indicate at least one of the following, and the PRU may assume that at least one of the following is specified using the format information): Sample-based and / or path-based measurements; For a parameter, one value or multiple values, Priority of each parameter or combination of parameters, A combination of the above.

[0165] The parameter value may be expressed as a range.

[0166] The priority may be used by the PRU to determine which measurement method / parameter to actually use when measurements based on multiple measurement methods / parameters are requested at the same time. For example, the PRU may perform measurements at a certain time using a measurement method / parameter with a higher priority.

[0167] The PRU may assume that it will receive the formatting information (or a second message containing that information) and that it will return a response to that formatting information (or that second message) to the LMF, which may be or be included in the third message described above.

[0168] The PRU may perform measurements based on measurement methods / parameters indicated by the format information, and may also perform measurements based on measurement methods / parameters not indicated by the format information.

[0169] The response may include at least one of the following: · PRU measurements held by the PRU; Whether the PRU measurements comply with (or correspond to) the requested reporting format; · Reporting formats for PRU measurements held by the PRU; · Reasons for not reporting PRU measurements according to the requested reporting format; A combination of the above.

[0170] The PRU measurements included in the response may be signaled using specific information elements (NR-PRU-DL-Info or NR-DL-TDOA-SignalMeasurementInformation) or may be reported using new information elements for reporting PRU measurements.

[0171] The PRU measurements included in the response may include one or more PRU measurements held by the PRU that correspond to the requested reporting format, or may not include any PRU measurements that correspond to the requested reporting format. The PRU measurements included in the response may include one or more PRU measurements that correspond to unrequested reporting formats instead of or in addition to one or more PRU measurements that correspond to the requested reporting format. Note that the PRU measurements held by the PRU may include measurements obtained before receiving the request for a reporting format, or may include measurements obtained after receiving the request.

[0172] The response may indicate a reporting format corresponding to the PRU measurements included in the response, so that the UE can conveniently determine whether the PRU measurements included in the response comply with the requested reporting format.

[0173] The report format corresponding to the PRU measurement included in the response may be indicated by format information. For example, the value of the indicator may be associated with a specific report format [information]. This association may be predefined or pre-established between the PRU and the LMF.

[0174] 12 is a diagram illustrating an example of notification of a report format corresponding to PRU measurement in the second embodiment. In this example, the NR-DL-TDOA-SignalMeasurementInformation information element includes a format information field (nr-measurementformat-r19).

[0175] Also, as shown in FIG. 10, the NR-PRU-DL-Info-r18 information element including a format information field (nr-measurementformat-r19) may be used for the response.

[0176] The report format corresponding to the PRU measurements included in the response may be restricted, for example, to report formats that use only values ​​smaller or larger than the value of a certain parameter indicated by the requested report format.

[0177] The information regarding whether the PRU measurement complies with (or corresponds to) the requested reporting format may correspond to the format information or may be represented by other information (e.g., a Boolean value) (e.g., TRUE indicates that the PRU measurement complies with the requested reporting format). In the present disclosure, the other information may also be included in (or defined as) the format information. Note that if neither the corresponding format information nor information regarding whether the PRU measurement complies with the requested reporting format is included in the response, it may be implicitly indicated that the PRU measurement complies with the requested reporting format.

[0178] The LMF may determine the report format to be subsequently requested based on the report format of the PRU measurements held by the PRU contained in the response. The LMF can reliably obtain the PRU measurements held by the PRU by requesting a report format selected from the report formats of the PRU measurements held by the PRU.

[0179] The reason for not reporting the PRU measurements according to the requested reporting format may be indicated by a specific failure message, which may indicate, for example, one or a combination of the following: The PRU does not have PRU measurements in accordance with the requested reporting format; The PRU does not support the measurement method specified by the requested reporting format; · The PRU does not support measurements using the parameters specified by the requested reporting format.

[0180] Regarding the reason for not reporting the PRU measurement according to the requested report format, information (such as the ID of the PRU, format information associated with the ID / specific indicators described above, etc.) that can identify which PRU does not correspond to which measurement method / measurement using parameters specified by the report format may be included in the above response.

[0181] According to the second embodiment described above, the UE can request a report format from the LMF and preferably receive the desired PRU measurement corresponding to the report format.

[0182] <Supplementary> In the above embodiment, an example where the report format is requested / notification by format information is shown, but it is not limited to this. For example, instead of format information or together with a part of format information, information (such as a model ID) for specifying an AI model used for monitoring metric calculation may be used for specifying the report format. The report format suitable for the input of the AI model may be defined in advance or preset among the UE / LMF / PRU.

[0183] In steps S101 / S102, the UE / LMF may request the model ID. The LMF may determine the corresponding format information based on the model ID and send a request for the report format in step S102. The PRU may determine the corresponding format information based on the model ID and perform PRU measurement based on the format information. In steps S103 / S104, the PRU / LMF may return the model ID / format information corresponding to the PRU measurement.

[0184] <<Notification of Information to UE>> The notification of any information from the [Network (NW) (e.g., Base Station (BS))] to the UE (or in other words, the reception of any information from the BS by the UE) in the above-described embodiment may be performed using physical layer signaling (e.g., DCI), upper layer signaling (e.g., RRC signaling, MAC CE), a specific signal / channel (e.g., PDCCH, PDSCH, reference signal), or a combination thereof.

MR-DC may include dual connectivity between LTE (Evolved Universal Terrestrial Radio Access (E-UTRA)) and NR (E-UTRA-NR Dual Connectivity (EN-DC)), dual connectivity between NR and LTE (NR-E-UTRA Dual Connectivity (NE-DC)), etc.

[0203] In EN-DC, the LTE (E-UTRA) base station (eNB) is the master node (MN), and the NR base station (gNB) is the secondary node (SN). In NE-DC, the NR base station (gNB) is the MN, and the LTE (E-UTRA) base station (eNB) is the SN.

[0204] The wireless communication system 1 may support dual connectivity between multiple base stations within the same RAT (for example, dual connectivity in which both the MN and the SN are NR base stations (gNBs) (NR-NR Dual Connectivity (NN-DC))).

[0205] The wireless communication system 1 may include a base station 11 that forms a macrocell C1 with a relatively wide coverage, and base stations 12 (12a-12c) that are located within the macrocell C1 and form small cells C2 that are smaller than the macrocell C1. A user terminal 20 may be located within at least one of the cells. The location, number, shape, size, etc. of each cell and user terminal 20 are not limited to the embodiment shown in the figure. Hereinafter, when there is no need to distinguish between the base stations 11 and 12, they will be collectively referred to as base station 10.

[0206] The wireless communication system 1 may utilize Multi Input Multi Output (MIMO). For example, one cell may be formed by one antenna / base station 10, or may be formed by multiple antennas / base stations 10. One [virtual] cell (which may be called, for example, a super cell) may be composed of multiple [virtual] cells (which may be called, for example, sub-cells). A super cell may correspond to a cell whose physical range is fixed, and a sub-cell may correspond to a cell whose physical range varies semi-statically / dynamically. In this case, the wireless communication system 1 may be called a cell-free system.

[0207] The user terminal 20 may be connected to at least one of the multiple base stations 10. The user terminal 20 may utilize at least one of carrier aggregation (CA) using multiple component carriers (CC) and dual connectivity (DC).

[0208] Each CC may be included in at least one of a first frequency band (Frequency Range 1 (FR1)) and a second frequency band (Frequency Range 2 (FR2)). The macro cell C1 may be included in FR1, and the small cell C2 may be included in FR2. For example, FR1 may be a frequency band of 6 GHz or less (sub-6 GHz), and FR2 may be a frequency band above 24 GHz (above-24 GHz). Note that the frequency bands and definitions of FR1 and FR2 are not limited to these, and for example, FR1 may be a frequency band higher than FR2.

[0209] Furthermore, the user terminal 20 may perform communication using at least one of Time Division Duplex (TDD) and Frequency Division Duplex (FDD) in each CC.

[0210] The multiple base stations 10 may be connected by wire (for example, optical fiber conforming to the Common Public Radio Interface (CPRI), an X2 / Xn interface, etc.) or wirelessly (for example, NR communication). For example, when NR communication is used as a backhaul between the base stations 11 and 12, the base station 11 corresponding to the upper station may be called an Integrated Access Backhaul (IAB) donor, and the base station 12 corresponding to the relay station (relay) may be called an IAB node.

[0211] The base station 10 may be connected to the core network 30 directly or via another base station 10. The core network 30 may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), a Next Generation Core (NGC), and the like.

[0212] The core network 30 may include network functions (NFs) such as a User Plane Function (UPF), an Access and Mobility management Function (AMF), a Session Management Function (SMF), a Unified Data Management (UDM), an Application Function (AF), a Data Network (DN), a Location Management Function (LMF), and an Operation, Administration and Maintenance (Management) (OAM). Note that a single network node may provide multiple functions. Furthermore, communication with an external network (e.g., the Internet) may be performed via the DN.

[0213] The user terminal 20 may be a terminal compatible with at least one of communication methods such as LTE, LTE-A, and 5G.

[0214] An Orthogonal Frequency Division Multiplexing (OFDM)-based radio access scheme may be used in the radio communication system 1. For example, Cyclic Prefix OFDM (CP-OFDM), Discrete Fourier Transform Spread OFDM (DFT-s-OFDM), Orthogonal Frequency Division Multiple Access (OFDMA), Single Carrier Frequency Division Multiple Access (SC-FDMA), or the like may be used in at least one of the downlink (DL) and uplink (UL).

[0215] The radio access scheme may also be called a waveform. Note that in the wireless communication system 1, other radio access schemes (for example, other single-carrier transmission schemes, other multi-carrier transmission schemes) may be used as the UL and DL radio access schemes.

[0216] In the wireless communication system 1, a downlink shared channel (Physical Downlink Shared Channel (PDSCH)) shared by each user terminal 20, a broadcast channel (Physical Broadcast Channel (PBCH)), a downlink control channel (Physical Downlink Control Channel (PDCCH)), etc. may be used as the downlink channel.

[0217] Furthermore, in the wireless communication system 1, an uplink shared channel (Physical Uplink Shared Channel (PUSCH)) shared by each user terminal 20, an uplink control channel (Physical Uplink Control Channel (PUCCH)), a random access channel (Physical Random Access Channel (PRACH)), etc. may be used as an uplink channel.

[0218] The PDSCH transmits user data, higher layer control information, System Information Block (SIB), etc. The PUSCH may transmit user data, higher layer control information, etc. Furthermore, the PBCH may transmit Master Information Block (MIB).

[0219] Lower layer control information may be transmitted by the PDCCH. The lower layer control information may include, for example, Downlink Control Information (DCI) including scheduling information for at least one of the PDSCH and the PUSCH.

[0220] Note that the DCI for scheduling the PDSCH may be referred to as a DL assignment, a DL DCI, etc., and the DCI for scheduling the PUSCH may be referred to as an UL grant, a UL DCI, etc. Note that the PDSCH may be interpreted as DL data, and the PUSCH may be interpreted as UL data.

[0221] A control resource set (CORESET) and a search space may be used to detect the PDCCH. The CORESET corresponds to resources to search for DCI. The search space corresponds to a search region and a search method for PDCCH candidates. One CORESET may be associated with one or more search spaces. The UE may monitor a CORESET associated with a certain search space based on the search space configuration.

[0222] One search space may correspond to PDCCH candidates corresponding to one or more aggregation levels. One or more search spaces may be called a search space set. Note that the terms "search space," "search space set," "search space setting," "search space set setting," "CORESET," "CORESET setting," etc. in the present disclosure may be read interchangeably.

[0223] The PUCCH may transmit uplink control information (UCI) including at least one of channel state information (CSI), acknowledgement information (which may be called, for example, Hybrid Automatic Repeat reQuest ACKnowledgement (HARQ-ACK), ACK / NACK, etc.), and scheduling request (SR). The PRACH may transmit a random access preamble for establishing a connection with a cell.

[0224] In the present disclosure, downlink, uplink, etc. may be expressed without adding "link." Also, various channels may be expressed without adding "Physical" to the beginning.

[0225] In the wireless communication system 1, a synchronization signal (SS), a downlink reference signal (DL-RS), etc. may be transmitted. In the wireless communication system 1, a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS), a demodulation reference signal (DMRS), a positioning reference signal (PRS), a phase tracking reference signal (PTRS), etc. may be transmitted as DL-RS.

[0226] The synchronization signal may be, for example, at least one of a Primary Synchronization Signal (PSS) and a Secondary Synchronization Signal (SSS). A signal block including the SS (PSS, SSS) and the PBCH (and DMRS for the PBCH) may be referred to as an SS / PBCH block, an SS Block (SSB), or the like. Note that the SS, SSB, and the like may also be referred to as reference signals.

[0227] Furthermore, in the wireless communication system 1, a sounding reference signal (SRS), a demodulation reference signal (DMRS), etc. may be transmitted as an uplink reference signal (UL-RS). Note that the DMRS may also be called a user equipment-specific reference signal (UE-specific reference signal).

[0239] The transmitting / receiving unit 120 (RF unit 122) may perform modulation to a radio frequency band, filtering, amplification, etc. on the baseband signal, and transmit the radio frequency band signal via the transmitting / receiving antenna .

[0240] On the other hand, the transmitting / receiving unit 120 (RF unit 122) may perform amplification, filtering, demodulation to a baseband signal, etc. on the radio frequency band signal received by the transmitting / receiving antenna .

[0260] Whether or not to apply DFT processing may be based on the setting of transform precoding. When transform precoding is enabled for a certain channel (e.g., PUSCH), the transceiver unit 220 (transmission processing unit 2211) may perform DFT processing as the transmission processing to transmit the channel using a DFT-s-OFDM waveform, and when transform precoding is not enabled, the transceiver unit 220 may not perform DFT processing as the transmission processing.

These functional blocks (components) are realized by any combination of at least one of hardware and software. Furthermore, the method for realizing each functional block is not particularly limited. That is, each functional block may be realized using a single device that is physically or logically coupled, or may be realized using two or more physically or logically separated devices that are directly or indirectly connected (for example, using wires, wirelessly, etc.) and these multiple devices.

The output device 1006 is an output device (for example, a display, a speaker, a light emitting diode (LED) lamp, etc.) that outputs to the outside. The input device 1005 and the output device 1006 may be integrated into one device (for example, a touch panel).

[0283] Furthermore, each device, such as the processor 1001 and the memory 1002, is connected by a bus 1007 for communicating information. The bus 1007 may be configured using a single bus, or may be configured using different buses between each device.

A component carrier (CC) may also be called a cell, frequency carrier, carrier frequency, etc.

[0287] A radio frame may be composed of one or more periods (frames) in the time domain. Each of the one or more periods (frames) constituting a radio frame may be called a subframe. Furthermore, a subframe may be composed of one or more slots in the time domain. A subframe may have a fixed time length (e.g., 1 ms) that is independent of numerology.

[0288] Here, the numerology may be a communication parameter applied to at least one of transmission and reception of a signal or channel, and may indicate at least one of, for example, a subcarrier spacing (SCS), a bandwidth, a symbol length, a cyclic prefix length, a transmission time interval (TTI), the number of symbols per TTI, a radio frame structure, a specific filtering process performed by a transceiver in the frequency domain, and a specific windowing process performed by a transceiver in the time domain.

[0289] A slot may be composed of one or more symbols in the time domain (such as an Orthogonal Frequency Division Multiplexing (OFDM) symbol or a Single Carrier Frequency Division Multiple Access (SC-FDMA) symbol), and may be a time unit based on numerology.

[0290] A slot may include multiple minislots. Each minislot may consist of one or multiple symbols in the time domain. A minislot may also be called a subslot. A minislot may consist of fewer symbols than a slot. A PDSCH (or PUSCH) transmitted in a time unit larger than a minislot may be called PDSCH (PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using a minislot may be called PDSCH (PUSCH) mapping type B.

[0291] A radio frame, a subframe, a slot, a minislot, and a symbol all represent time units for transmitting signals. The radio frame, the subframe, the slot, the minislot, and the symbol may be referred to by other names corresponding to the radio frame, the subframe, the slot, the minislot, and the symbol. Note that the time units such as a frame, a subframe, a slot, a minislot, and a symbol in the present disclosure may be interchangeable.

[0292] For example, one subframe may be referred to as a TTI, or multiple consecutive subframes may be referred to as a TTI, or one slot or one minislot may be referred to as a TTI. That is, at least one of a subframe and a TTI may be a subframe (1 ms) in existing LTE, a period shorter than 1 ms (for example, 1-13 symbols), or a period longer than 1 ms. Note that the unit representing the TTI may be called a slot, minislot, etc., instead of a subframe.

[0293] Here, TTI refers to, for example, the smallest time unit for scheduling in wireless communication. For example, in an LTE system, a base station performs scheduling to allocate radio resources (such as frequency bandwidth and transmission power that can be used by each user terminal) to each user terminal in TTI units. However, the definition of TTI is not limited to this.

[0294] The TTI may be a transmission time unit for a channel-encoded data packet (transport block), a code block, a code word, etc., or may be a processing unit for scheduling, link adaptation, etc. When a TTI is given, the time interval (e.g., the number of symbols) to which a transport block, a code block, a code word, etc. is actually mapped may be shorter than the TTI.

[0295] When one slot or one minislot is called a TTI, one or more TTIs (i.e., one or more slots or one or more minislots) may be the minimum time unit for scheduling. Also, the number of slots (minislots) constituting the minimum time unit for scheduling may be controlled.

[0296] A TTI having a time length of 1 ms may be called a regular TTI (TTI in 3GPP Rel. 8-12), normal TTI, long TTI, regular subframe, normal subframe, long subframe, slot, etc. A TTI shorter than a regular TTI may be called a shortened TTI, short TTI, partial or fractional TTI, shortened subframe, short subframe, minislot, subslot, slot, etc.

[0297] In addition, a long TTI (e.g., a normal TTI, a subframe, etc.) may be interpreted as a TTI having a time length of more than 1 ms, and a short TTI (e.g., a shortened TTI, etc.) may be interpreted as a TTI having a TTI length shorter than the TTI length of a long TTI and equal to or greater than 1 ms.

[0298] A resource block (RB) is a resource allocation unit in the time domain and the frequency domain, and may include one or more consecutive subcarriers in the frequency domain. The number of subcarriers included in an RB may be the same regardless of numerology, for example, 12. The number of subcarriers included in an RB may also be determined based on numerology.

[0299] In addition, an RB may include one or more symbols in the time domain and may have a length of one slot, one minislot, one subframe, or one TTI. One TTI, one subframe, etc. may each be composed of one or more resource blocks.

[0300] Note that one or more RBs may also be called a physical resource block (PRB), a sub-carrier group (SCG), a resource element group (REG), a PRB pair, an RB pair, etc.

[0301] Furthermore, a resource block may be composed of one or more resource elements (REs). For example, one RE may be a radio resource region of one subcarrier and one symbol.

[0302] A Bandwidth Part (BWP), which may also be referred to as a fractional bandwidth, may represent a subset of contiguous common resource blocks (RBs) for a given numerology on a given carrier, where the common RBs may be identified by their index relative to a common reference point of the carrier. PRBs may be defined in a given BWP and numbered within that BWP.

[0303] The BWP may include an UL BWP (a BWP for UL) and a DL BWP (a BWP for DL). One or more BWPs may be configured for a UE within one carrier.

[0304] At least one of the configured BWPs may be active, and the UE may not expect to transmit or receive a given signal / channel outside the active BWP. Note that the terms "cell," "carrier," etc. in this disclosure may be read as "BWP."

[0305] The above-described structures of radio frames, subframes, slots, minislots, symbols, etc. are merely examples. For example, the number of subframes included in a radio frame, the number of slots per subframe or radio frame, the number of minislots included in a slot, the number of symbols and RBs included in a slot or minislot, the number of subcarriers included in an RB, the number of symbols in a TTI, the symbol length, the cyclic prefix (CP) length, etc. may be changed in various ways.

[0306] Furthermore, the information, parameters, etc. described in the present disclosure may be expressed using absolute values, may be expressed using relative values ​​from a predetermined value, or may be expressed using other corresponding information. For example, a radio resource may be indicated by a predetermined index.

[0307] The names used for parameters and the like in this disclosure are not intended to be limiting in any way. Furthermore, the mathematical expressions and the like using these parameters may differ from those explicitly disclosed in this disclosure. The various channels (PUCCH, PDCCH, etc.) and information elements may be identified by any suitable names, and therefore the various names assigned to these various channels and information elements are not intended to be limiting in any way.

[0313] Note that the physical layer signaling may be called Layer 1 / Layer 2 (L1 / L2) control information (L1 / L2 control signal), L1 control information (L1 control signal), etc. Furthermore, the RRC signaling may be called an RRC message, such as an RRC connection setup message or an RRC connection reconfiguration message. Furthermore, the MAC signaling may be notified using, for example, a MAC Control Element (CE).

[0314] Furthermore, notification of specified information (e.g., notification that "it is X") is not limited to explicit notification, but may be made implicitly (e.g., by not notifying the specified information or by notifying other information).

[0315] The determination may be made by a value represented by one bit (0 or 1), by a Boolean value represented by true or false, or by a comparison of numerical values ​​(e.g., comparison with a predetermined value).
