[0027] FIG. 2 is a diagram showing an example of an AI model (AI / ML model). This example shows an AI model including a ResNet as model component #1, a Transformer model as model component #2, a dense layer, and a normalization layer. In this way, one AI model may be included as a component of another AI model. Note that FIG. 2 may also show an AI model in which processing proceeds from left to right.

[0029] The inference information for the AI ​​model may include information regarding decision tree branch pruning, parameter quantization, etc.

[0030] The performance information about the AI ​​model may include information about the expected value of a loss function defined for the AI ​​model.

[0031] AI model information regarding a specific AI model may be predetermined in a standard or may be notified to a UE from a network (NW). An AI model defined in a standard may be called a reference AI model. AI model information regarding a reference AI model may be called reference AI model information.

[0032] Note that the AI ​​model information in the present disclosure may include an index for identifying the AI ​​model (for example, may be referred to as an AI model index). The AI ​​model information in the present disclosure may include an AI model index in addition to or instead of the input / output information of the AI ​​model described above. The association between the AI ​​model index and the AI ​​model information (for example, input / output information of the AI ​​model) may be predetermined in a standard or may be notified to the UE from the NW.

[0033] (UE positioning) 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.

[0034] 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).

[0035] Fingerprinting location estimates the UE's location based on a database / AI model from the fingerprints of the UE's multiple transmission paths (multipath).

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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 RSRP of the reference signal.

[0040] 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.

[0041] 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 reference signals (and additionally RSRP, 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.

[0042] 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.).

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] The assistance information may include information regarding at least one of the following: Timing Error Group (TEG), RSRPP (path-specific RSRP), Expected angle, Adjacent beam information, TRP antenna / beam information, LOS / NLOS indicators, -Additional path reporting.

[0048] 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.

[0049] The RSRPP may indicate the measurement result of the RSRP on the first pass.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] As additional beam information, the neighboring beam information may include information about a subset of DL-PRS resources (Option 1) for the purpose of prioritizing DL-AoD reports, or the boresight direction of each DL-PRS resource (Option 2), allowing for optimization of UE Rx beam sweeping and DL-AoD measurements.

[0054] 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.

[0055] The LOS / NLOS indicator may indicate information regarding Line Of Sight (LOS) / Non-Line Of Sight (NLOS).

[0056] 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).

[0057] 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 and 2 in the assistance information.

[0058] Option 1: A 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.

[0059] 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.

[0060] 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 UEs and gNBs. PRU may also be interpreted as UEs, gNBs, transmission reception points (TRPs), or transmission points (TPs).

[0061] 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 relative to the reference device (e.g., Relative Time of Arrival (RTOA) / Time Difference Between Arrival and Arrival, AoA) to the LMF; Operational, 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, reporting 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.

[0062] There are two use cases for positioning using AI models: Direct AI / machine learning (ML) positioning, AI / ML assisted positioning.

[0063] Positioning using such AI / ML technology may be called AI-based positioning.

[0064] 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.

[0065] 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 time of arrival). 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).

[0066] 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).

[0067] (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 entity's) model is used and whether measurement results of either DL or UL signals are used for location prediction:

[0068] Figures 3A to 3C are diagrams showing variations of positioning using DL signals, and Figures 4A and 4B are diagrams showing variations of positioning using UL signals.

[0069] Case 1: UE-based positioning using a UE-side model (direct AI / ML positioning or AI / ML-assisted positioning). Case 2a: UE-assisted / LMF-based positioning using a UE-side model (AI / ML-assisted positioning). Case 2b: UE-assisted / LMF-based positioning using LMF-side model (direct AI / ML positioning). Case 3a: NG-RAN node-assisted positioning using gNB-side model (AI / ML-assisted positioning). Case 3b: NG-RAN node-assisted positioning (direct AI / ML positioning) using LMF-side model.

[0070] <Case 1> Case 1 is an example of positioning using a UE-side model and DL signals / channels (see Figure 3A). 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).

[0071] <Case 2a> Case 2a is an example of positioning using a UE-side model and DL signals / channels (see Figure 3B). 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).

[0072] <Case 2b> Case 2b is an example of positioning using the LMF-side model and DL signals / channels (see Figure 3C). 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.

[0073] <Case 3a> Case 3a is an example of positioning using a gNB-side model and UL signals / channels (see Figure 4A). 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.

[0074] <Case 3b> Case 3b is an example of positioning using the LMF-side model and UL signals / channels (see Figure 4B). 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.

[0075] (Sample-based positioning / Path-based positioning) In AI / ML-based positioning in future wireless communication systems, the introduction of sample-based measurements and path-based measurements as measurements for input to the model is being considered.

[0076] <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.

[0077] Timing information for Nt' samples may be measured / reported with timing measurement granularity T.

[0078] 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.

[0079] The corresponding measurements (eg, power) may correspond to measurements of the reported Nt' samples.

[0080] 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).

[0081] The timing information may be specified relative to a reference time.

[0082] The timing reporting granularity factor k may be signaled, for example, using the upper layer parameter timingReportingGranularityFactor.

[0083] 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).

[0084] Fig. 5 is a diagram showing an example of sample-based measurement of positioning. In the example shown in Fig. 5, Nt' samples are selected from Nt samples and measured.

[0085] <Path-based measurement> Path-based measurements may be measurements that include measurement reports in existing specifications (eg, up to Rel. 18).

[0086] Timing information related to path-based measurements may be measured / reported with timing measurement granularity T.

[0087] T may be determined based at least on the timing reporting granularity factor k.

[0088] The definition of the path may be determined based on the implementation of the UE / NW.

[0089] The recommended value of k may be notified from the LMF to the base station / UE using higher layer signaling (e.g., NRPPa / LPP).

[0090] (Data collection for positioning) As mentioned above, the introduction of AI / ML-based positioning is being considered for future wireless communication systems (for example, Rel. 19 and later).

[0091] When performing AI / ML-based positioning, it is considered that data collection for training an AI / ML model is performed, and that information for this data collection includes information about measurements and information about labels.

[0092] In the present disclosure, information related to measurement, information used for measurement, information for measurement, measurement information, measurement related information, and Part A may be read interchangeably. In the present disclosure, information related to measurement may include at least one of a channel measurement value, a quality indicator of the channel measurement (value), and a timestamp of the channel measurement (value).

[0093] In the present disclosure, information about a label, information for a label, label information, label-related information, and Part B may be interchangeable. In the present disclosure, information about a label may include at least one of a ground truth label (or an approximation), a quality indicator of the label, and a timestamp of the label. In the present disclosure, a timestamp of a label may refer to time / time information corresponding to the label.

[0094] Corresponding Part A and Part B may be for the same UE (eg, PRU / non-PRU) and may be for the same location associated with Part B.

[0095] For example, Part A and Part B may be generated by the same or different entities based on the same UE, or Part A and Part B may be generated based on the same UE in the same or different positioning methods / procedures.

[0096] It is contemplated that the generation of parts A and B will be performed by a specific entity in each use case of AI-based positioning.

[0097] For example, in Cases 1 / 2a / 2b, Part A may be generated by a PRU or a non-PRU UE, and in Cases 1 / 2a / 2b, Part B may be generated by a PRU, a non-PRU UE with a location estimate, or an LMF.

[0098] For example, in Case 3a / 3b, Part A may be generated by the TRP / gNB (base station). Also, in Case 3a, Part B may be generated by at least the LMF. In Case 3b, Part B may be generated by the PRU, a non-PRU UE with location estimation, or the LMF.

[0099] For example, in case 1 / 2a, the UE may generate part A / B. In this case, the generation of part A / B may be based on the implementation of the UE.

[0100] For example, in case 1 / 2a, the LMF may generate Part B. In this case, the UE may report Part A and other information to the LMF according to existing methods (specified in Rel. 18). The LMF may send Part B to the UE as assistance information.

[0101] For example, in case 2b, the UE may generate part A / B, in which case the UE may report part A / B to the LMF.

[0102] For example, in case 2b, the LMF may generate Part B. In this case, the UE may report Part A and other information to the LMF according to existing methods (specified in Rel. 18).

[0103] For example, in case 3a, the TRP / base station may generate Part A. In this case, the generation of Part A may be based on the implementation of the TRP / base station.

[0104] For example, in case 3a, the LMF may generate at least Part B. In this case, the TRP / base station may report Part A and other information to the LMF according to existing methods (specified in Rel. 18). The LMF may send Part B to the TRP / base station as assistance information.

[0105] For example, in case 3b, the TRP / base station may generate Part A. In this case, the generation of Part A may be based on the implementation of the TRP / base station.

[0106] For example, in case 3b, the LMF may generate Part B. In this case, the TRP / base station may report Part A and other information to the LMF according to existing methods (specified in Rel. 18).

[0107] For example, in case 3b, the UE may generate Part B. In this case, the UE may report Part A and other information to the LMF.

[0108] (timestamp) For the collection of training data in the above-mentioned cases 3a / 3b, the timestamp of the channel measurement / measurement report can be made using the existing information element (IE) "timestamp". In both cases 3a / 3b, the measurement results can be generated by the TRP / gNB and sent / reported to the LMF.

[0109] When a channel measurement (measurement result) is reported / transmitted, the timestamp of the channel measurement may refer to (correspond to) the time instance at which the channel measurement was performed.

[0110] Also, when a label is reported / transmitted, the timestamp of the label may refer to (correspond to) the time instance when the label is valid.

[0111] (Quality Indicator) The introduction of a quality indicator (QI) for a measurement / label is being considered. A quality indicator (QI) may be a parameter that indicates the quality of a measurement / label.

[0112] For example, for the QI in the case of timing information (measurement information) in Part A, a parameter related to timing quality (nr-TimingQuality / NR-TimingQuality, Timing Measurement Quality, etc.) may be used.

[0113] For example, the QI for location information (label information) in Part B may use existing information elements (e.g., defined up to Rel. 18) (e.g., a parameter indicating the uncertainty of location coordinates (e.g., LocationUncertainty)).

[0114] For example, in case 1, location label data is generated by the LMF and transmitted from the LMF to the UE. In this case, the label / label quality indicator may be transmitted using an existing IE (locationCoordinates). The locationCoordinates may indicate an estimated location using at least one of the geographic shapes defined by the specification.

[0115] The above-mentioned parameters indicating the uncertainty or confidence level of the location information, location estimate (location coordinates) can be used as quality indicators of the label.

[0116] (analysis) By the way, the following methods are being considered for obtaining training data for AI / ML-based positioning.

[0117] For example, in the above-mentioned cases 3a / 3b, it is assumed that, in generating the training data, Part A (which may simply be called "measurements"), information related to measurements, and Part B (which may simply be called "labels"), information related to labels, are generated by different entities.

[0118] Figure 6 shows an example of measurement / label generation in positioning. As shown in Figure 6, measurement (Part A) generation can be performed by the TRP / gNB. In addition, in case 3a / 3b, label generation can be performed in the LMF. In case 3b, label generation can be performed by the UE (non-PRU) / PRU.

[0119] In this case, the respective timestamps (which may be called association data) may be taken into account to perform pairing (association) of Part A and Part B.

[0120] Here, it is assumed that the validity of the label (Part B) changes due to the movement of the UE or changes in the surrounding environment.

[0121] For example, associating labels with inappropriate measurements (Part A) may result in inaccurate training (and inaccurate training results).

[0122] In other words, it is necessary to clarify the criteria for judging the effectiveness of labels.

[0123] If these are not clear, the positioning training procedure may not be performed properly, which may affect the positioning accuracy, and as a result, the communication throughput / quality may be affected.

[0124] Therefore, the present inventors came up with a method for solving these problems.

[0159] (Wireless communication method) Embodiments of the present disclosure relate to AI-based positioning and can be broadly categorized as follows: 0th embodiment: Definition of label validity. First embodiment: Label validity over time. Second embodiment: Effectiveness of the label considering the environment.

[0160] Each embodiment will be described below based on these. Each embodiment / option may be applied alone or in combination.

[0161] In this disclosure, positioning is mainly exemplified as a use case of the AI ​​model. More specifically, the embodiments of the present disclosure are applicable to any positioning use case (downstream positioning / upstream positioning, UE / gNB / LMF-based positioning).

[0162] The present disclosure can be applied to any positioning method. For example, the present disclosure can be applied not only to DL / UL TDOA but also to DL AoD / UL AoA, multi-RTT, and E-CID-based positioning. In this case, the upper layer parameters (information elements) corresponding to each method may be interchangeable.

[0163] In this disclosure, the measurement entity may be a TRP / gNB, and the label generator may be an LMF in case 3a, or a PRU / non-PRU / UE / LMF in case 3b.

[0164] In this disclosure, cases 3a and 3b are exemplified where the measurement and label generation are performed by different entities, but are not limited to these. This disclosure can also be applied to cases 1 and 2, or cases where the measurement and label generation are performed by the same entity.

[0165] The UE / NW (gNB / LMF) may perform positioning / model monitoring and various related operations (measurement / prediction / reporting / transmission / reception) by applying the various provisions described above and the embodiments described below.

[0166] The UE / NW (gNB) may receive various configurations for positioning / measurement / reporting, and may further report / send corresponding prediction (positioning) results to the NW (LMF).

[0167] The NW (gNB / LMF) may send various settings for positioning / measurement / reporting to the UE / gNB, and the NW may receive corresponding prediction results (reports) from the UE / gNB.

[0168] The UE / NW (gNB / LMF) may control various positioning-related operations (transmission and reception of related information) by applying the embodiments of the present disclosure and the various provisions described above. Furthermore, the UE / NW (gNB / LMF) may execute information exchange between multiple entities to realize these various operations.

[0169] According to the embodiments of the present disclosure, the rules for generating positioning training data are clarified. As a result, the positioning training procedure is properly executed, and the positioning accuracy can be improved. As a result of the improved positioning accuracy, improvements in communication throughput / quality can be expected.

[0170] <0th embodiment> The 0th embodiment relates to the definition of the validity of a label.

[0171] The validity of a label [information] may be defined as follows: Validity may also be called validity, validation, etc.

[0172] The validity of a label may mean that a measurement and a label can be paired (associated), or that the label itself is available / usable / applicable.

[0173] The validity of a label may be defined for each entity that generates the corresponding label, i.e., the validity of a label may be different or the same for each generating entity.

[0174] Alternatively, the validity of a label may be defined for each combination of label generating entity and measurement generating entity, i.e. the validity of a label may be different or the same for each combination of label generating entity and measurement generating entity.

[0175] The validity of the label may be predefined by the specification, may be set / indicated (statically / dynamically) by higher layer / physical layer signaling, or may be determined according to the UE capabilities.

[0176] The validity of a label may have different definitions / values / settings for each type of label, for example, different definitions / values / settings may be applied to the measurement metric label in case 3a and the location label in case 3b.

[0177] According to this embodiment, the validity of the label is clearly defined.

[0178] First Embodiment The first embodiment relates to time-dependent label validity (time-dependence of label validity).

[0179] The validity of a label may be defined based on time (taking time into account). A measurement and a label may be paired if and only if the label is valid.

[0180] <<Pairing conditions>> The pairing conditions for measurements and labels will be described below, and time may be taken into consideration in the pairing conditions.

[0181] If the error (time difference) between the measurement timestamp and the label timestamp is within / less than a predefined time X (symbols / frames / slots / milliseconds), the measurement and label may be paired.

[0182] The measurement timestamp may refer to the measurement timing, and the label timestamp may refer to the label timing (e.g., the label generation timing).

[0183] The value of X mentioned above may be predefined by a specification, may be set / indicated by higher layer signaling / physical layer signaling, or may be determined according to UE capabilities.

[0184] The timestamp error / difference value mentioned above (which may also be referred to as the time difference between the measurement and the label) may be represented by at least one of the following options: Figures 7A to 7C show an example of criteria for determining the validity of the labels of the present disclosure.

[0185] (Opt1) A given time span relative to either the measurement / label timestamp.

[0186] For example, as shown in Fig. 7A, it may be a predetermined time range before and after a certain timestamp as a reference. The reference timestamp may be either a measurement or a label.

[0187] (Opt2) Start and end times [relative to either the measurement / label timestamp]. Start / end times may be expressed as absolute times or relative to a reference.

[0188] For example, as shown in Figure 7B, it may be expressed by a start time and an end time. In this case, the reference timestamp may or may not be included between the start time and the end time. The reference timestamp may be either a measurement or a label.

[0189] (Opt3) A start time (based on either a measurement or label timestamp) and a duration (a given length of time). The start time can be expressed as an absolute time or relative to a reference.

[0190] For example, as shown in Figure 7C, it may be represented by a start time and a certain duration. In this case, the reference timestamp may or may not be included within the certain duration. The reference timestamp may be either a measurement or a label.

[0191] (Note) In each of the above options, only the time after the reference time (reference timestamp) may be considered for validity [determination].

[0192] <<valid time / period>> A time / period may be defined during which the label [information] is valid [regardless of its relationship to the measurement timestamp]. This time / period may be called the label validity time / period.

[0193] The time for which the label is valid may be predefined by a specification, may be set / indicated by higher layer signaling / physical layer signaling, or may be determined according to the UE capabilities.

[0194] The time that a label is valid may be represented by at least one of the following options: Figures 8A-8E are diagrams illustrating an example of the time that a label of the present disclosure is valid.

[0195] (Opt1) A given time range / duration after the label's timestamp (see Figure 8A).

[0196] (Opt2) A given time range / duration before and after the label's timestamp (see Figure 8B).

[0197] (Opt3) Between the label timestamp and the end time (see Figure 8C). The end time may be expressed as absolute time or relative time from the reference (the label timestamp).

[0198] (Opt4) Between the start and end times relative to the label timestamp (see Figure 8D). The start and end times can be expressed as absolute times or relative times from the reference (the label timestamp).

[0199] In this case, the timestamp of the reference label may or may not be included between the start time and the end time.

[0200] (Opt5) A predetermined duration from the start time based on the label timestamp (see Figure 8E). The start time may be expressed as an absolute time or as a relative time from the reference (the label timestamp).

[0201] In this case, the timestamp of the reference label may or may not be included between the start time and the end time.

[0202] <<Valid Time-Based Pairing>> One or more measurements taken within the time / period that a label [information] is valid may be paired with that label [information].

[0203] If only one measurement is paired with a label, The measurement with the timestamp closest to the label's timestamp may be paired, or The measurement for which the label is valid and the quality indicator (the measurement with the smallest uncertainty) may be paired, or Measurements for which the label is valid and has the highest confidence level may be paired.

[0204] As conditions for pairing, quality indicators (uncertainty, confidence level) may be defined.

[0205] The UE / gNB may report to the NW (e.g., LMF) the quality of the pairing itself, taking into account measurements, label timestamp deviations (difference values), quality indicators, etc.

[0206] When there are multiple labels, the conditions (the predetermined time X and the label validity time described above) for pairing the labels with the measurements may be common to all labels or may be different for each label.

[0207] As described above, the predetermined time X and the label validity time, which are common to all labels or different for each label, may be predefined by the specification, may be set / instructed by upper layer signaling / physical layer signaling, or may be determined according to the UE capabilities. Alternatively, it may depend on the UE implementation.

[0208] FIG. 9 is a diagram showing an example of determining the validity of labels in the UE movement of the present disclosure. As shown in FIG. 9, the predetermined time X (tα, tβ, tγ) may be the same or different for different times (t1, t2, t3).

[0209] <​​​​​​​​​​​​​​​​​​In addition, different predetermined times X, label valid times, and label [information] may be set for different parameters such as bearing and uncertainty.

[0214] 10A and 10B are diagrams showing examples of information elements that may be included in the higher layer parameters (LPP / NRPPa) of the present disclosure.

[0215] As shown in FIG. 10A, the parameters related to the velocity types (VelocityTypes) may include horizontal / vertical velocity, or parameters related to these velocities and uncertainties.

[0216] As shown in FIG. 10B, the parameter related to the horizontal velocity (HorizontalVelocity) may include a parameter related to the direction (bearing), a parameter related to the horizontal speed (horizontalSpeed), and the like.

[0217] <<Measurement / Label Quality Indicators>> For the validity of the label, quality indicators of the measurement / label may be taken into account.

[0218] The UE / gNB may be instructed / requested to report quality indicators of the measurements / labels, which may include at least one of a timing quality parameter (NR-TimingQuality), a measurement quality parameter (MeasurementQuality), a location coordinate parameter (locationCoordinates), an uncertainty parameter (uncertainty), a confidence level parameter (confidence level), and information related thereto.

[0219] The UE / gNB may be instructed / requested to report these quality indicators simultaneously / asynchronously (separately) with the timestamps mentioned above.

[0220] The validity of the label may take into account whether the measurement is sample-based / path-based, information about the RS (RS opportunity period, band, etc.), assistance data such as TRP location, and additional conditions on the network side. The UE / gNB may be instructed / requested to report this information simultaneously / asynchronously (separately) with the above-mentioned timestamp.

[0221] The LMF may instruct / request the UE / gNB to report measurements / labels at a frequency that satisfies the conditions regarding the validity of the labels, or the UE may instruct / request the gNB / LMF to report measurements / labels at a frequency that satisfies the conditions regarding the validity of the labels.

[0222] If the report from the UE / gNB does not satisfy the conditions regarding the label validity, the UE / gNB may assume that the LMF will send information about the error (which may include the error cause), or in this case the UE / gNB may assume that it will receive (send) an instruction to remeasure / retransmit the measurement / label.

[0223] The UE / gNB may be provided with additional assistance data regarding the validity of the label. Examples of the additional assistance data include: · UE position / metric uncertainty per unit time. Expected variance of UE location / metric per unit time. Rate of change of UE position / metric per unit time.

[0224] According to this embodiment, the rules (criteria, etc.) regarding the validity of labels in consideration of time are clarified, and the UE / gNB can appropriately recognize / determine the measurement / label pairing based on the rules.

[0225] <Second embodiment> The second embodiment relates to the effectiveness of a label taking into account the environment (environmental dependence of the effectiveness of the label).

[0226] The validity of the label [information] may be defined / set based on the instructions of the NW.

[0227] The UE / gNB may assume that the NW determined the validity of the label [information] based on time, surrounding environmental information, quality indicators, etc.

[0228] If the error (difference) between the ambient environment information in the timestamp of the measurement and the ambient environment information in the timestamp of the label is within / less than a predetermined condition, the measurement and the label may be paired.

[0229] The ambient environment information may include at least one of the number of additional paths, the timing report granularity factor k, and the number of [measurement] samples (Nt, Nt').

[0230] The UE / gNB may be instructed / requested to report the surrounding environment information simultaneously / asynchronously (separately) with the above-mentioned timestamp.

[0231] The above-mentioned predetermined conditions may be predefined by a specification, may be set / indicated by higher layer signaling / physical layer signaling, may be determined according to UE capabilities, or may be left to the UE implementation.

[0232] For the validity of the label, quality indicators of the measurement / label may be taken into account.

[0233] The UE / gNB may be instructed / requested to report quality indicators of the measurements / labels, which may include at least one of a timing quality parameter (NR-TimingQuality), a measurement quality parameter (MeasurementQuality), a location coordinate parameter (locationCoordinates), an uncertainty parameter (uncertainty), a confidence level parameter (confidence level), and information related thereto.

[0234] The UE / gNB may be instructed / required to report these quality indicators simultaneously / asynchronously (separately) with the timestamps described above.

[0235] If the report from the UE / gNB does not meet the conditions regarding the validity of the label, the UE / gNB may assume that it will receive information about an error (which may include the error cause) from the LMF. Alternatively, in this case, the UE / gNB may assume that it will receive (be sent) an instruction to re-measure / resend the measurement / label [information].

[0236] According to this embodiment, the regulations (criteria, etc.) regarding the validity of the label considering the environment are clarified. The UE / gNB can appropriately recognize / judge the pairing of the measurement / label based on the said regulations.

[0237] <Supplementary Note> <<Notification of Information to the UE>> The notification of any information from the [Network (NW) (e.g., Base Station (BS))] to the UE in the above-described embodiment (in other words, the reception of any information from the BS by the UE) 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. <00008​​​​​​When the above notification is performed by DCI, the above notification may be performed according to a specific field of the DCI, a Radio Network Temporary Identifier (RNTI) used for scrambling Cyclic Redundancy Check (CRC) bits assigned to the DCI, a format of the DCI, and the like.

[0254] (wireless communication system) The configuration of a wireless communication system according to an embodiment of the present disclosure will be described below. In this wireless communication system, communication is performed using any one of the wireless communication methods according to the above embodiments of the present disclosure or a combination thereof.

[0255] 11 is a diagram illustrating an example of a schematic configuration of a wireless communication system according to an embodiment. The wireless communication system 1 (which may be simply referred to as system 1) may be a system that realizes communication using Long Term Evolution (LTE), 5th generation mobile communication system New Radio (5G NR), or the like, which are specified by the Third Generation Partnership Project (3GPP).

[0256] The wireless communication system 1 may also support dual connectivity between multiple Radio Access Technologies (RATs) (Multi-RAT Dual Connectivity (MR-DC)). 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.

[0257] 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.

[0258] 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))).

[0259] 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.

[0260] 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.

[0261] 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).

[0262] 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.

[0263] 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.

[0264] 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.

[0265] 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.

[0269] 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.

[0270] 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.

[0272] 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).

[0273] 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.

[0274] 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.

[0275] 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.

[0276] 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.

[0277] 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.

[0278] 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.

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.

[0280] 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.

[0281] 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).

[0331] Storage 1003 is a computer-readable recording medium and may be constituted by at least one of, for example, a flexible disk, a floppy disk, a magneto-optical disk (e.g., a compact disc (e.g., a Compact Disc ROM (CD-ROM)), a digital versatile disc, a Blu-ray disc), a removable disk, a hard disk drive, a smart card, a flash memory device (e.g., a card, stick, key drive), a magnetic stripe, a database, a server, or other suitable storage medium. Storage 1003 may also be referred to as a secondary storage device.

[0332] The communication device 1004 is hardware (transmission / reception device) for communicating between computers via at least one of a wired network and a wireless network, and is also referred to as, for example, a network device, a network controller, a network card, or a communication module. The communication device 1004 may be configured to include a high-frequency switch, a duplexer, a filter, a frequency synthesizer, etc. to realize at least one of frequency division duplex (FDD) and time division duplex (TDD). For example, the above-mentioned transmission / reception unit 120 (220), transmission / reception antenna 130 (230), etc. may be realized by the communication device 1004. The transmission / reception unit 120 (220) may be implemented as a transmission unit 120a (220a) and a reception unit 120b (220b) that are physically or logically separated.

[0333] The input device 1005 is an input device (for example, a keyboard, a mouse, a microphone, a switch, a button, a sensor, etc.) that receives input from the outside. 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).

[0334] 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.

[0335] Furthermore, the base station 10 and the user terminal 20 may be configured to include hardware such as a microprocessor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a programmable logic device (PLD), or a field programmable gate array (FPGA), and some or all of the functional blocks may be realized using such hardware. For example, the processor 1001 may be implemented using at least one of these pieces of hardware.

[0336] Note that the devices included in the core network 30 (for example, network nodes that provide NFs) may also be realized by the above-described functional block / hardware configuration.

[0337] (Variation) Note that terms explained in the present disclosure and terms necessary for understanding the present disclosure may be replaced with terms having the same or similar meanings. For example, a channel, a symbol, and a signal (signal or signaling) may be interchangeable. A signal may also be a message. A reference signal may be abbreviated as RS, and may also be called a pilot, pilot signal, etc. depending on the applicable standard. A component carrier (CC) may also be called a cell, frequency carrier, carrier frequency, etc.

[0338] 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.

[0339] 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.

[0340] 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.

[0341] 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.

[0342] 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.

[0343] 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.

[0344] 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.

[0345] 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.

[0346] 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.

[0347] 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.

[0348] 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.

[0349] 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.

[0350] 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.

[0351] 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.

[0352] 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.

[0353] 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.

[0354] 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.

[0355] 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."

[0356] 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.

[0357] 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.

[0358] 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.

[0360] Furthermore, information, signals, etc. may be output from a higher layer to a lower layer and / or from a lower layer to a higher layer. Information, signals, etc. may be input / output via multiple network nodes.

[0361] Input and output information, signals, etc. may be stored in a specific location (for example, memory) or may be managed using a management table. Input and output information, signals, etc. may be overwritten, updated, or added. Output information, signals, etc. may be deleted. Input information, signals, etc. may be transmitted to another device.

[0364] 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).

[0365] 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).

[0366] 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).

[0368] Software, instructions, information, etc. may also be transmitted or received over a transmission medium. For example, if software is transmitted from a website, server, or other remote source using wired technologies (such as coaxial cable, fiber optic cable, twisted pair, Digital Subscriber Line (DSL)), and / or wireless technologies (such as infrared, microwave), then these wired and / or wireless technologies are included within the definition of transmission media.

When a base station accommodates multiple cells, the overall coverage area of ​​the base station can be divided into multiple smaller areas, and each smaller area can be provided with communication service by a base station subsystem (e.g., a small indoor base station (Remote Radio Head (RRH))). The term "cell" or "sector" refers to a part or the entire coverage area of ​​a base station and / or base station subsystem that provides communication service within this coverage.

It may also be applied to a combination of multiple systems (e.g., a combination of LTE or LTE-A and 5G).

[0403] As used in this disclosure, the phrase "based on" does not mean "based only on," unless expressly stated otherwise. In other words, the phrase "based on" means both "based only on" and "based at least on."

[0404] As used in this disclosure, any reference to an element using a designation such as "first," "second," etc. does not generally limit the quantity or order of those elements. These designations may be used in this disclosure as a convenient method of distinguishing between two or more elements. Thus, a reference to a first and a second element does not imply that only two elements may be employed or that the first element must in some way precede the second element.

[0405] The term "determining," as used in this disclosure, may encompass a wide variety of actions. For example, "determining" may be considered to be judging, calculating, computing, processing, deriving, investigating, looking up, search, inquiry (e.g., looking up in a table, database, or another data structure), ascertaining, etc.

[0406] Additionally, "determining" may be considered to be "determining" receiving (e.g., receiving information), transmitting (e.g., sending information), input, output, accessing (e.g., accessing data in memory), etc.

[0407] Furthermore, "determination" may be considered to be "determining" resolving, selecting, choosing, establishing, comparing, etc. In other words, "determination" may be considered to be "determining" some action.

(if the above "..." is a to-infinitive, a verb with "to")," etc. "does not expect ..." may be interchangeably read as "be not expected ...," "does not ... (if the above "..." is a to-infinitive, a verb with "to")," etc. Furthermore, "An apparatus A is not expected ..." may be interchangeably read as "an apparatus B other than apparatus A does not expect ... from apparatus A" (for example, if apparatus A is a UE, apparatus B may be a base station).

[0410] The "maximum transmit power" in this disclosure may mean the maximum value of transmit power, the nominal UE maximum transmit power, or the rated UE maximum transmit power.

[0411] As used in this disclosure, the terms "connected," "coupled," or any variation thereof, refer to any direct or indirect connection or coupling between two or more elements, and may include the presence of one or more intermediate elements between two elements that are "connected" or "coupled" to each other. The coupling or connection between elements may be physical, logical, or a combination thereof. For example, "connected" may be read as "access."

[0412] In this disclosure, when two elements are connected, they may be considered to be "connected" or "coupled" to one another using one or more wires, cables, printed electrical connections, etc., as well as using electromagnetic energy having wavelengths in the radio frequency range, microwave range, light (both visible and invisible) range, etc., as some non-limiting and non-exhaustive examples.

[0413] In the present disclosure, the term "A and B are different" may mean "A and B are different from each other." The term may also mean "A and B are each different from C." Terms such as "separate" and "coupled" may also be interpreted in the same way as "different."

[0414] When used in this disclosure, the terms "include," "including," and variations thereof are intended to be inclusive, similar to the term "comprising." Furthermore, when used in this disclosure, the term "or" is not intended to be an exclusive or.

[0415] In this disclosure, where articles are added by translation, such as a, an, and the in English, the disclosure may include that the nouns following these articles are in the plural form.

[0416] In the present disclosure, terms such as "less than or equal to," "less than," "greater than," "more than," "equal to," etc. may be interchangeable. Furthermore, in the present disclosure, terms meaning "good," "bad," "big," "small," "high," "low," "fast," "slow," "wide," "narrow," etc. may be interchangeable, not limited to the positive, comparative, and superlative. Furthermore, in the present disclosure, terms meaning "good," "bad," "big," "small," "high," "low," "fast," "slow," "wide," "narrow," etc. may be interchangeable, not limited to the positive, comparative, and superlative, as expressions with the prefix "i-th" (i is any integer) (for example, "highest" may be interchangeable as "i-th highest").

[0417] In this disclosure, the terms "of," "for," "regarding," "related to," "associated with," etc. may be read interchangeably.

[0418] In the present disclosure, terms such as "when A, B," "if A, (then) B," "B upon A," "B in response to A," "B based on A," "B during / while A," "B before A," "B at (the same time as) / on A," "B after A," "B since A," and "B until A" may be interchangeable. Note that A, B, and the like herein may be replaced with appropriate expressions, such as nouns, gerunds, and regular sentences, depending on the context. Note that the time difference between A and B may be nearly zero (immediately after or immediately before). A time offset may be applied to the time at which A occurs. For example, "A" may be interchangeable with "before / after the time offset at which A occurs." The time offset (eg, one or more symbols / slots) may be predefined or may be specified by the UE based on signaled information.

[0419] In the present disclosure, timing, time, duration, time instance, any time unit (e.g., slot, subslot, symbol, subframe), period, occasion, resource, etc. may be read interchangeably.

[0420] Although the invention according to the present disclosure has been described in detail above, it is clear to those skilled in the art that the invention according to the present disclosure is not limited to the embodiments described in the present disclosure. The description of the present disclosure is for illustrative purposes only and does not impose any limiting meaning on the invention according to the present disclosure.
