[0029] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The embodiments described below are merely examples, and embodiments to which the present invention is applied are not limited to the following embodiments.

[0030] (System Structure)

[0031] Figure 1 1 is a diagram for explaining a wireless communication system in an embodiment of the present invention. Figure 1 As shown, the wireless communication system according to the embodiment of the present invention includes a base station 10 and a terminal 20. Furthermore, the core network includes an LMF 30 capable of communicating with the base station 10. Furthermore, the LMF 30 can also communicate with the base station 10 via the AMF. The LMF 30 is an example of a network device. The base station 10 is also an example of a network device.

[0032] exist Figure 1 Although one base station 10 and one terminal 20 are shown, this is merely an example and may be multiple. For example, multiple base stations 10 may be provided to transmit DL-PRS (positioning reference signals) received by terminal 20. One, multiple, or all of the multiple base stations 10 may be airborne devices (e.g., satellites or HAPS).

[0033] The transmission source of a DL-PRS signal can also be referred to as a TRP (transmission reception point). A TRP can be referred to as either a transmission point or a reception point. A TRP can be a base station, an extended antenna unit (e.g., an O-RU) attached to a base station, or any other device. An extended antenna unit can also be referred to as a base station.

[0034] Base station 10 is a communication device that provides one or more cells and conducts wireless communications with terminal 20. Physical resources for wireless signals are defined in the time and frequency domains. The time domain can be defined by the number of OFDM symbols, while the frequency domain can be defined by the number of subcarriers or resource blocks. Furthermore, in the time domain, a TTI (Transmission Time Interval) can be a time slot or a subframe. Furthermore, cell and CC can be considered synonymous.

[0035] The base station 10 can perform carrier aggregation for bundling multiple cells (multiple CCs (Component Carriers)) to communicate with the terminal 20. In carrier aggregation, one PCell (Primary Cell) and one or more SCells (Secondary Cells) are used.

[0036] The base station 10 sends synchronization signals and system information to the terminal 20. Synchronization signals are, for example, NR-PSS and NR-SSS. System information is sent, for example, via NR-PBCH or PDSCH, and is also called broadcast information. Figure 1 As shown, the base station 10 transmits control signals or data to the terminal 20 via the DL (downlink) and receives control signals or data from the terminal 20 via the UL (uplink). Here, content transmitted via control channels such as the PUCCH and PDCCH is referred to as control signals, while content transmitted via shared channels such as the PUSCH and PDSCH is referred to as data. These terms are merely examples. Furthermore, UCI (Uplink Control Information) is transmitted via the PUCCH or PUSCH.

[0037] The terminal 20 is a communication device having a wireless communication function, such as a smartphone, a mobile phone, a tablet computer, a wearable terminal, or an M2M (Machine-to-Machine) communication module. Figure 1 As shown, terminal 20 receives control signals or data from base station 10 via DL and transmits control signals or data to base station 10 via UL, thereby utilizing various communication services provided by the wireless communication system. Alternatively, terminal 20 may be referred to as a UE and base station 10 as a gNB.

[0038] Terminal 20 can perform carrier aggregation, which bundles multiple cells (multiple CCs (component carriers)) to communicate with base station 10. Carrier aggregation uses one PCell (primary cell) and one or more SCells (secondary cells). Alternatively, a PUCCH-SCell with a PUCCH can be used.

[0039] The Location Management Function (LMF) 30 is a function (device) responsible for communication control related to the location information service specified in 5GC. The LMF 30 may also be referred to as a location management server, location management device, or network device. For example, the LMF 30 can receive reference signal measurement results (such as phase, received power, time difference, and angle) from the terminal 20 or base station 10 and calculate the location of the terminal 20. Furthermore, the LMF 30 can provide configuration information or control information related to positioning to the terminal 20 and base station 10.

[0040] Figure 2 FIG. 1 shows a configuration example of a wireless communication system in which DC (Dual Connectivity) is performed. Figure 2As shown, a base station 10A serving as a MN (Master Node) and a base station 10B serving as a SN (Secondary Node) are provided. The base stations 10A and 10B are each connected to a core network 40. The terminal 20 can communicate with both the base stations 10A and 10B.

[0041] The cell group provided by base station 10A, acting as an MN, is called an MCG (Master Cell Group), and the cell group provided by base station 10B, acting as an SN, is called an SCG (Secondary Cell Group). In DC, an MCG consists of one PCell and one or more SCells, while an SCG consists of one PSCell (Primary SCell) and one or more SCells.

[0042] The processing actions in this embodiment can be Figure 1 The system structure shown can also be implemented by Figure 2 In the following description, unless otherwise specified, " / " means "or", unless otherwise indicated by the context.

[0043] (About the topic)

[0044] As mentioned above, the use of sub-THz is being studied for 6G. For example, in situations where positioning can be performed using multiple frequencies, such as sub-THz and existing frequencies, the use of multiple frequencies to measure LOS-NLOS indicators is being considered.

[0045] The LOS-NLOS-Indicator feature was introduced in Rel-17. By associating the LOS-NLOS-Indicator with PRS resource units / TRP units and notifying the base station 10 / LMF 30, for example, from the terminal 20, the indicator can be used as positioning assistance information in the base station 10 / LMF 30. The base station 10 / LMF 30 may also be referred to as the network (NW).

[0046] Here, the LOS-NLOS-Indicator is explained. The LOS-NLOS-Indicator is, for example, an indicator value that indicates the likelihood of a line-of-sight (LOS) of sight (LOS) of the PRS propagation path from the transmission source (e.g., TRP) to the receiver (e.g., terminal 20). While the LOS-NLOS-Indicator is described below as an information element and its value, the LOS-NLOS-Indicator value can also be expressed as a LOS-NLOS-Indicator value. Furthermore, the LOS-NLOS-Indicator can also be referred to as an "indicator value indicating a LOS-NLOS state."

[0047] In this embodiment, the LOS / NLOS indicator has both soft and hard values. The soft value represents the likelihood of a line of sight (LOS) on the propagation path, using a numerical value (probability estimate) between 0 and 1 with a resolution of 0.1. A value of 0 indicates NLOS (non-line-of-sight), and 1 indicates LOS (line of sight).

[0048] The hard value indicates whether the visibility state of the propagation path from the transmission source (for example, TRP) to the receiver (for example, terminal 20) is LOS (true) or NLOS (false).

[0049] In this embodiment, terminal 20 can perform LOS / NLOS determination using, for example, a sub-THz signal and a conventional frequency signal transmitted from base station 10. Any LOS / NLOS determination method can be used, including, for example, a method that measures the arrival time of a signal. For ease of description, the LOS-NLOS-Indicator may be referred to as "indicator."

[0050] By measuring indicators at multiple frequencies as described above, the terminal 20 is expected to report many indicators to the base station 10 / LMF 30. This may increase the payload size.

[0051] In particular, when there are many resources such as sub-THz, and when indicators are used at multiple frequencies, the effect of increased payload size is significant.

[0052] Furthermore, even for multiple resources in a QCL relationship (i.e., considered the same beam at different frequencies), the probability of completely identical indicator values ​​is low. Therefore, many indicators must be reported, but to minimize the payload size, the number of indicators must be reduced.

[0053] The following describes techniques for reducing the payload size associated with indicator reports.

[0054] (Overview of Implementation Methods)

[0055] Hereinafter, as embodiments for solving the above-mentioned problems, Embodiments 0 to 5 will be described. The outlines of Embodiments 0 to 5 are as follows. Embodiments 0 to 5 can be implemented in any combination.

[0056] Embodiment 0 (High-level proposal): The number of indicators reported by the terminal 20 is reduced. The terminal 20 can report a number of indicators that is different from the number of indicators measured in each of a plurality of frequency bands.

[0057] Embodiment 1: The terminal 20 determines the indicator to be reported based on the quality associated with the indicator.

[0058] Embodiment 2: Priorities are set among indicators, and the terminal 20 determines the indicator to be reported according to the priorities.

[0059] Embodiment 3: A timer is set in the terminal 20 to assume reception of a reference signal required for indicator calculation, and the terminal 20 determines the indicator to be reported according to the timer.

[0060] Embodiment 4: A tolerance is set between indicators, and the terminal 20 determines the indicator to be reported according to the tolerance.

[0061] Embodiment 5: The terminal 20 comprehensively utilizes the conditions of Embodiments 1 to 4 to determine the indicator to be reported.

[0062] In Embodiments 0 to 5, the terminal 20 is the entity that reports the indicator, but the reporting entity may be the base station 10, the LMF 30, or a network node device other than the base station 10 / LMF 30.

[0063] Each embodiment will be described in detail below. Embodiment 0 is a basic example, and its detailed examples correspond to Embodiments 1 to 5. Any or all of Embodiments 0 to 5 can be combined and implemented. However, it is also possible to implement Embodiments 1 to 4 separately without considering Embodiment 0.

[0064] (Implementation Method 0)

[0065] First, Embodiment 0 will be described. In Embodiment 0, the number of indicators reported by Terminal 20 is reduced. Terminal 20 can report a number of indicators that differs from the number of indicators measured in each of multiple frequency bands. Using "frequency band" as the unit of measurement is merely an example. Frequencies within a "frequency band" can also be used as the unit of measurement. Furthermore, "frequency" can also have a certain bandwidth. Furthermore, "frequency" can be broadened to include "frequency band."

[0066] Reference Figure 3 An example of operation in Embodiment 0 will be described. In S101, terminal 20 receives a signal transmitted from base station 10 at frequency A. In S102, terminal 20 receives a signal transmitted from base station 10 at frequency B. These signals are, for example, but not limited to, PRS.

[0067] In S103 , terminal 20 measures (calculates) indicators using signals from frequency A and frequency B. For example, terminal 20 measures three indicators using three PRS resources from frequency A, and three indicators using three PRS resources from frequency B, for a total of six indicators.

[0068] In S104 , the terminal 20 selects six or fewer (eg, three) indicators from the six indicators, and reports the selected indicators to the base station 10 / LMF 30 .

[0069] Specifically, in Embodiment 0, when terminal 20 measures NA, NB, NC, ... indicators at multiple frequencies A, B, C, ..., it reports NA + NB + NC + ... or less indicators. In other words, terminal 20 assumes that it does not necessarily need to report all of the measured indicators.

[0070] The multiple frequencies A, B, C, . . . can be any frequencies, and among the multiple frequencies, for example, any one or any multiple of FR1, FR2, FR3, sub-THz, THz, etc. can be included.

[0071] Regarding the granularity of frequency, the terminal 20 can report the indicator at any of the following granularities, for example.

[0072] Per UE (terminal unit: all frequencies used by the terminal)

[0073] Per FR (in FR)

[0074] Per band (in band units)

[0075] Per CC = per PFL (positioning frequency layer) (in PFL units)

[0076] Per band combination (in units of band combination)

[0077] Among the various granularities described above, the terminal 20 can report the indicator at, for example, the following resource granularity.

[0078] Per TRP (in TRP)

[0079] Per PRS resource (in units of PRS resources)

[0080] In Embodiment 0, the terminal 20 can report the capability (capability information) of the number of reportable indicators to the NW (eg, the base station 10 / LMF 30). The granularity of reporting the number of capability indicators can be any of the following granularities, for example.

[0081] Per UE

[0082] Per FR

[0083] Per band

[0084] Per CC = per PFL

[0085] Per band combination

[0086] The terminal 20 may assume that after the indicator is reported, the NW will instruct the terminal 20 on the frequency of positioning based on the indicator. This type of positioning may also be referred to as two-stage positioning.

[0087] Reference Figure 4 An example operation including reporting of capability will be described. In S201 , the terminal 20 reports, for example, to the base station 10 / LMF 30 , a capability indicating that the number of indicators that the terminal 20 (assuming that each UE (Per UE)) can report is N.

[0088] In S202, terminal 20 measures indicators. Here, it is assumed that M indicators are obtained. In S203, terminal 20 reports a maximum of N and maximum of M indicators to base station 10 / LMF 30. In S204, terminal 20 receives an indication from base station 10 / LMF 30, for example, regarding the frequency at which terminal 20 should perform positioning.

[0089] In addition, the terminal 20 may also receive an indication (or setting) of the report content from the base station 10 / LMF 30. The "report content" may be, for example, any one or more of the number of indicators to be reported, the granularity of the report, and the indicators to be reported (e.g., for which TRP the indicator is for, for which PRS resource the indicator is for, etc.).

[0090] Figure 5 An example of the operation in this case is shown below: In S301 , the terminal 20 receives an instruction on the report content (eg, a maximum of N, with a granularity of PRS resource units) from the base station 10 / LMF 30 .

[0091] In S302 , the terminal 20 measures indicators. Assume that M (M>N) indicators are obtained. In S303 , the terminal 20 reports the N indicators to the base station 10 / LMF 30 .

[0092] According to the embodiment 0, it is possible to perform reporting while reducing resources for reporting indicators, thereby suppressing overhead.

[0093] (Implementation Method 1)

[0094] Next, Embodiment 1 will be described. In Embodiment 1, terminal 20 determines the indicator to be reported based on the quality associated with the indicator. Embodiment 1 includes Opt. 1 and Opt. 2, so each will be described separately.

[0095] <Implementation Method 1: Opt. 1>

[0096] In Opt. 1, terminal 20 measures existing reception quality parameters for signals received for indicator measurement and compares the measured values ​​with threshold S (S ≥ 0). For example, terminal 20 reports M (M ≥ 0) indicators measured based on signals whose measured values ​​exceed threshold S (S ≥ 0) to base station 10 / LMF 30.

[0097] Alternatively, the terminal 20 may report M (M≧0) indicators based on signals whose measurement values ​​are smaller than a threshold value S (S≧0) to the base station 10 / LMF 30 .

[0098] The above-mentioned reception quality parameters can be, for example, NR-TimingQuality described in non-patent document 1, or Measurement Quality and CQI described in 3GPP TS38.455, or parameters other than these.

[0099] <Implementation Method 1: Opt. 2>

[0100] Opt. 2 newly defines the indicator quality. The indicator quality can be determined, for example, based on the reception quality of the signal transmitted from the base station 10 used to measure the indicator. In this case, for example, it is assumed that the better the reception quality, the higher the indicator quality.

[0101] Terminal 20 measures the indicator, determines the quality of the indicator, and compares the quality with a threshold value S (S ≥ 0). For example, terminal 20 reports M (M ≥ 0) indicators whose quality exceeds threshold value S (S ≥ 0) to base station 10 / LMF 30. Alternatively, terminal 20 may report M (M ≥ 0) indicators whose quality exceeds threshold value S (S ≥ 0) to base station 10 / LMF 30.

[0102] The threshold S of Opt. 1 and the threshold S of Opt. 2 may be different or the same. Furthermore, in both Opt. 1 and Opt. 2, the threshold S may be notified by the NW (e.g., base station 10 / LMF 30 ) via RRC, MAC-CE, or DCI, or may be specified by the specification.

[0103] Furthermore, in Opt. 2, the terminal 20 may also report the quality (Quality) together with an indicator of the quality (Quality) to the base station 10 / LMF 30. Furthermore, the quality (Quality) may also be replaced by uncertainty (Uncertainty).

[0104] Figure 6 This figure shows what the quality in Opt. 2 looks like when it is added to Non-Patent Document 1.

[0105] According to the first embodiment, the terminal 20 can report the reception quality taking the indicator into consideration.

[0106] (Implementation Method 2)

[0107] Next, a description will be given of Embodiment 2. In Embodiment 2, priorities are set among indicators, and the terminal 20 determines an indicator to be reported according to the priorities.

[0108] For example, the terminal 20 reports N (0≤N≤NA+NB+NC+...) indicators to the base station 10 / LMF 30 in descending order of priority.

[0109] Priority levels may be defined by a specification or indicated by the NW (e.g., base station 10 / LMF 30) to terminal 20. The designation method may be any of RRC, MAC-CE, and DCI. Alternatively, after multiple priority candidates are assigned to terminal 20 by base station 10 / LMF 30 via RRC, the actual priority level to be used may be designated to terminal 20 via MAC-CE / DCI.

[0110] In addition, the priority may be defined / specified in units of indicators, may be defined / specified in units of frequencies, may be defined / specified in units of TRPs, or may be defined / specified in units of PRS resources.

[0111] The priority in units of indicators means that, when indicator 1, indicator 2, and indicator 3 exist, the priority is set to "indicator 2 > indicator 1 > indicator 3".

[0112] The priority in frequency units means, for example, setting the priority to "indicator of FR3 > indicator of FR2 > indicator of FR1".

[0113] Furthermore, as for the method of prioritization, priority may be assigned to all indicators, or to NA, NB, NC, etc., of each frequency.

[0114] In addition to prioritization, a minimum number of indicators to be reported in each frequency may be specified. For example, a minimum of one indicator may be reported in each frequency.

[0115] According to the second embodiment, for example, only indicators suitable for positioning assistance information among measured indicators can be reported.

[0116] (Implementation Method 3)

[0117] Next, we will describe Embodiment 3. In Embodiment 3, terminal 20 is provided with a timer designed to receive the reference signal required for indicator calculation. Terminal 20 determines which indicator to report based on this timer. The following describes how to start the timer and the operations using the timer. Regarding the start of the timer, there are the following Opt. I and Opt. II.

[0118] <Timer Start: Opt. I>

[0119] In Opt. I, the terminal 20 uses the measurement instruction of the indicator from the NW (eg, the base station 10 / LMF 30) as a trigger for starting the timer. In other words, the terminal 20 starts the timer when it receives the measurement instruction of the indicator from the NW.

[0120] <Timer Start: Opt. II>

[0121] In Opt. II, the terminal 20 uses the reception of an RS (reference signal) required for calculating a reference indicator as a trigger to start the timer. Specifically, the terminal 20 starts the timer when it receives the RS (reference signal) required for calculating a reference indicator from the network. Alternatively, the terminal 20 may receive the reference indicator in advance from the network as AD (Assistance Data). AD (Assistance Data) is an IE used to provide information required for positioning between the UE and the LMF in advance via LPP.

[0122] Regarding the operation using the timer, there are the following Opt. 1 to 3.

[0123] <Action using timer: Opt.1>

[0124] In Opt. 1, the terminal 20 reports only the indicator values ​​that can be calculated (measured) by the timer expiration to the base station 10 / LMF 30. For indicators that cannot be calculated by the timer expiration, the terminal 20 does not report or reports null.

[0125] If the terminal 20 does not report the indicator before the timer expires, or if the terminal 20 reports null after the timer expires, the terminal 20 can assume that "with respect to the indictor, the NW (for example, the base station 10 / LMF 30) recognizes that there is an unmeasurable report" or "with respect to the indictor, the NW (for example, the base station 10 / LMF 30) recognizes that NLOS is reported."

[0126] <Action using timer: Opt.2>

[0127] In Opt. 2, terminal 20 reports the values ​​of indicators that can be calculated before the timer expires to base station 10 / LMF 30. For indicators that cannot be calculated before the timer expires, terminal 20 supplements them with a prescribed value R (0 ≤ R ≤ 1) and reports them. In other words, terminal 20 reports the prescribed value R for indicators that cannot be calculated before the timer expires. For example, terminal 20 reports R = 0 (i.e., the value determined to be NLOS).

[0128] The prescribed value R may be defined by a specification, or may be instructed / set by the NW (eg, the base station 10 / LMF 30 ) to the terminal 20 .

[0129] <Action using timer: Opt.3>

[0130] In Opt. 3, the terminal 20 returns a measurement failure for indicators that cannot be calculated before the timer expires. More specifically, there are the following Opt. 3.1 and Opt. 3.2.

[0131] Opt. 3.1: The terminal 20 returns a measurement failure to the NW (eg, the base station 10 / LMF 30 ) regarding an indicator that cannot be calculated during measurement instructed by the NW (eg, the base station 10 / LMF 30 ).

[0132] Opt. 3.2: If Terminal 20 cannot calculate any of the measurements instructed by the NW (e.g., base station 10 / LMF 30), Terminal 20 returns a measurement failure message to the NW (e.g., base station 10 / LMF 30) for each indicator associated with all of the instructed measurements. Alternatively, Terminal 20 returns a single measurement failure message to the NW (e.g., base station 10 / LMF 30) indicating that all indicators for all of the instructed measurements failed.

[0133] <Implementation 3: Sequence Example>

[0134] Reference Figure 7 The above-mentioned operation example will be described. In S401, the terminal 20 receives a measurement instruction from the base station 10 / LMF 30. It is assumed that the measurement instruction instructs measurement of indicator_A and indicator_B.

[0135] exist Figure 7 In the example of FIG, in S402, the measurement of indicator_A of terminal 20 is successful, but in S403, the measurement of indicator_B fails.

[0136] In Opt. I, the terminal 20 starts the timer when receiving the measurement indicator in S401. In Opt. II, the terminal 20 starts the timer when receiving the reference signal required for measurement (calculation) of indicator_A in S402.

[0137] If the measurement of indicator_B is unsuccessful and the timer expires, in S404, the terminal 20 performs any one of the above-mentioned Opt. 1 to 3 reports.

[0138] According to the third embodiment described above, the terminal 20 can reduce the resources of the indicators measured within a certain period of time and report them.

[0139] (Implementation Method 4)

[0140] Next, a description will be given of Embodiment 4. In Embodiment 4, a tolerance is set between indicators, and the terminal 20 determines the indicator to be reported according to the tolerance.

[0141] <About tolerance>

[0142] The above-mentioned tolerance (tolerance value) may be notified by the NW (e.g., base station 10 / LMF 30) to the terminal 20 or may be specified by a specification. If the tolerance is specified by a specification, different tolerance values ​​may be specified based on the relationship between indicators.

[0143] For example, different values ​​may be specified for the permissible error between bands (eg, between the indicator of band A and the indicator of band B) and the permissible error between FRs (eg, between the indicator of FR1 and the indicator of FR2).

[0144] <Action Example 1 Using Tolerance>

[0145] Terminal 20 can compare the values ​​of the indicators and, for example, report only those indicators whose differences between them are within (or may be within) a tolerance Y (>0) to base station 10 / LMF 30. For example, assuming the tolerance is within 0.2, if terminal 20 obtains the following results: indicator_A = 0.3, indicator_B = 0.2, indicator_C = 0.1, and indicator_D = 0.6, terminal 20 would only report indicator_B = 0.2 and indicator_C = 0.1.

[0146] Furthermore, for example, assuming that the allowable error is 0.2, when the terminal 20 obtains two results, indicator_A=0.3 and indicator_B=0.6, the terminal 20 may not report any indicator.

[0147] <Action Example 2 Using Tolerance>

[0148] Furthermore, the terminal 20 can compare the values ​​of the indicators and, for example, return a measurement failure if the difference between the indicators is greater than a tolerance Y (>0). More specifically, there are Opt. 3.1 and Opt. 3.2.

[0149] <Opt.3.1 of Action Example 2>

[0150] The terminal 20 returns a measurement failure to the base station 10 / LMF 30 only for an indicator that the size of the difference is greater than the allowable error.

[0151] For example, in the example of (tolerance=0.3, indicator_A=0.3, indicator_B=0.2, indicator_C=0.1, indicator_D=0.7), the terminal 20 returns a measurement failure message to the base station 10 / LMF 30 only for indicator_D.

[0152] Furthermore, when the tolerance is 0.2 and indicator_A = 0.3 and indicator_B = 0.6 are calculated, a measurement failure may be reported to the base station 10 / LMF 30 for each of indicator_A and indicator_B. This operation may also be considered as the operation of Opt. 3.2.

[0153] <Opt.3.2 of Action Example 2>

[0154] When it is detected that the difference between any of the multiple indicators measured at a certain timing exceeds the allowable error, the terminal 20 returns a measurement failure message to the base station 10 / LMF 30 for all the indicators (the multiple indicators).

[0155] In the above example (tolerance=0.3, indicator_A=0.3, indicator_B=0.2, indicator_C=0.1, indicator_D=0.7), the terminal 20 returns a measurement failure (measurement failure) for each of indicators_A to D to the base station 10 / LMF 30 .

[0156] <Other Examples of Implementation 4>

[0157] In the fourth embodiment, instead of the above-mentioned allowable error between indicators, the error in reception quality between indicators (the reception quality of a reference signal used to measure the indicator) or the error in uncertainty between indicators (the quality described in the first embodiment) may be used.

[0158] According to the fourth embodiment described above, for example, only indicators suitable for positioning assistance information among measured indicators can be reported.

[0159] (Implementation method 5)

[0160] Next, a description will be given of Embodiment 5. In Embodiment 5, the terminal 20 comprehensively utilizes the conditions of Embodiments 1 to 4 to determine the indicator to be reported.

[0161] For example, the NW (eg, base station 10 / LMF 30 ) instructs / sets each indicator reporting condition in any one, any plurality, or all of Embodiments 1 to 4 to the terminal 20 , and the terminal 20 reports only the indicators that meet the reporting condition.

[0162] For example, when a condition of "reporting only indicators whose reception quality is equal to or greater than a certain threshold" in Embodiment 1 is set, the terminal 20 reports only indicators that satisfy the condition.

[0163] Furthermore, when multiple reporting conditions are set for the terminal 20, for example, the terminal 20 may determine the indicator to be reported by ANDing the multiple reporting conditions. Furthermore, when multiple reporting conditions are set for the terminal 20, the terminal 20 may determine the indicator to be reported by ORing the multiple reporting conditions.

[0164] For example, Figure 8 As shown, as a specific example of determination by AND of Embodiment 1 and Embodiment 2, there is the following operation example: For example, terminal 20 reports an indicator with a reception quality of a certain level or higher (Embodiment 1) and a priority from the highest to the Pth (Embodiment 2).

[0165] In addition, if Figure 9 As shown, as a specific example of determination by OR of Embodiments 3 and 4, there is the following operation example: For example, the terminal 20 reports the indicator received before the timer expires (Embodiment 3) or within the allowable error (Embodiment 4).

[0166] According to the fifth embodiment described above, mixed report conditions can be set, and the terminal 20 can perform various reports based on the report conditions.

[0167] (Other examples)

[0168] Hereinafter, an example applicable to any of Embodiments 0 to 5 will be described.

[0169] In Embodiments 0 to 5, when the base station 10 / LMF 30 notifies / instructs / configures information to the terminal 20, the method may be RRC, MAC-CE, or DCI.

[0170] “PRS (Positioning Reference Signal)” may also be replaced with “DL-PRS”, “UL-PRS (eg, SRS for positioning), SRS)”, or the like.

[0171] "SRS" can also be replaced by "SRS for MIMO" or "SRS for positioning." "CC" can also be replaced by "PFL." "NW" can also be replaced by "gNB," "TRP," "LMF," etc. Furthermore, "set / indicated by the NW" can be replaced by "configured / activated / indicated by the NW via RRC / MAC-CE / DCI."

The software that operates according to the embodiments of the present invention by the processor of the base station 10 and the software that operates according to the embodiments of the present invention by the processor of the terminal 20 can also be stored in random access memory (RAM), flash memory, read-only memory (ROM), EPROM, EEPROM, registers, hard disk (HDD), removable disk, CD-ROM, database, server, and other appropriate storage media.

[0274] In addition, the notification of information is not limited to the form / implementation method described in the present disclosure, and other methods may also be used. For example, the notification of information may be implemented through physical layer signaling (e.g., DCI (Downlink Control Information), UCI (Uplink Control Information)), high-layer signaling (e.g., RRC (Radio Resource Control) signaling, MAC (Medium Access Control) signaling), broadcast information (MIB (Master Information Block), SIB (System Information Block)), other signals, or a combination thereof. In addition, RRC signaling may be referred to as an RRC message, for example, an RRC Connection Setup message, an RRC Connection Reconfiguration message, etc.

[0275] Each form / embodiment described in the present disclosure may also be applied to systems utilizing LTE (Long Term Evolution), LTE-A (LTE-Advanced), SUPER 3G, IMT-Advanced, 4G (4th generation mobile communication system), 5G (5th generation mobile communication system), 6th generation mobile communication system (6G), xth generation mobile communication system (xG) (xG (x is, for example, an integer or a decimal)), FRA (Future Radio Access), NR (New Radio), New Radio Access (NX), Future Generation Radio Access (FX), W-CDMA (registered trademark), GSM (registered trademark), CDMA2000, UMB (Ultra Mobile Broadband), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE At least one of 802.20, UWB (Ultra-WideBand), Bluetooth (registered trademark), other appropriate systems, and next-generation systems that extend, modify, create, or define these systems. Furthermore, a combination of multiple systems (for example, a combination of at least one of LTE and LTE-A with 5G) may be used.

[0276] The processing procedures, timings, and flows of each form / implementation described in this specification may be rearranged in order unless there is a conflict. For example, the methods described in this disclosure use an illustrative order to present the elements of various steps, but are not limited to the specific order presented.

[0277] In this specification, specific operations performed by base station 10 may also be performed by its upper node, depending on the situation. In a network consisting of one or more network nodes including base station 10, it is obvious that various operations for communicating with terminal 20 can be performed by at least one of base station 10 and other network nodes other than base station 10 (for example, but not limited to, an MME or S-GW). While the above example illustrates a single other network node other than base station 10, the other network node may also be a combination of multiple other network nodes (for example, an MME and an S-GW).

[0278] The information or signals described in this disclosure can be output from a higher layer (or lower layer) to a lower layer (or higher layer), and can also be input and output via multiple network nodes.

[0279] Input or output information can be stored in a specific location (e.g., memory) or managed using a management table. Input or output information can be overwritten, updated, or appended. Output information can also be deleted. Input information can also be transmitted to other devices.

[0280] The determination in the present disclosure may be performed using a value represented by one bit (0 or 1), a Boolean value (true or false), or a comparison of numerical values ​​(eg, comparison with a predetermined value).

[0281] Software, whether referred to as software, firmware, middleware, microcode, hardware description language, or by other names, shall be interpreted broadly to refer to instructions, sets of instructions, code, code segments, program code, programs, subroutines, software modules, applications, software applications, software packages, routines, subroutines, objects, executable files, execution threads, procedures, functions, etc.

[0282] Furthermore, software, commands, information, and the like may be transmitted and received via a transmission medium. For example, if software is transmitted from a web page, server, or other remote source using at least one of a wired technology (coaxial cable, fiber optic cable, twisted pair, DSL, etc.) and a wireless technology (infrared, microwave, etc.), then at least one of these wired and wireless technologies is included within the definition of a transmission medium.

[0283] The information, signals, and the like described in this disclosure may also be represented using any of a variety of different technologies. For example, data, commands, instructions, information, signals, bits, symbols, chips, and the like that may be referred to in the entire disclosure may be represented by voltage, current, electromagnetic waves, magnetic fields or magnetic particles, light fields or photons, or any combination thereof.

[0284] Furthermore, terms used in this disclosure and necessary for understanding this disclosure may be replaced with terms having the same or similar meanings. For example, at least one of a channel and a symbol may also be a signal (signaling). Furthermore, a signal may also be a message. Furthermore, a component carrier (CC) may also be referred to as a carrier frequency, a cell, or a frequency carrier.

[0285] As used in this disclosure, the terms "system" and "network" are used interchangeably.

[0286] In addition, the information, parameters, etc. described in this disclosure can be expressed using absolute values, relative values ​​relative to predetermined values, or other corresponding information. For example, wireless resources can be indicated using indexes.

[0287] The names used for the above parameters are non-limiting in any respect. Furthermore, the formulas used for these parameters may differ from those explicitly disclosed in this disclosure. Various channels (e.g., PUCCH, PDCCH, etc.) and information elements can be identified by any suitable name, and therefore the names assigned to these channels and information elements are non-limiting in any respect.

[0288] In this disclosure, terms such as "base station (BS)," "wireless base station," "base station," "fixed station," "NodeB," "eNodeB (eNB)," "gNodeB (gNB)," "access point," "transmission point," "reception point," "transmission / reception point," "cell," "sector," "cell group," "carrier," and "component carrier" are used interchangeably. Base stations are also sometimes referred to as macrocells, small cells, femtocells, and picocells.

[0289] A base station can accommodate one or more (for example, three) cells. When a base station accommodates multiple cells, the base station's overall coverage area can be divided into multiple smaller areas, each of which can also provide communication services through a base station subsystem (for example, a small base station for indoor use (RRH: Remote Radio Head)). Terms such as "cell" or "sector" refer to a portion or the entire coverage area of ​​at least one of the base station and base station subsystem providing communication services within that coverage area.

[0290] In the present disclosure, the base station sending information to the terminal may be replaced by the base station instructing the terminal to perform control or action based on the information.

[0291] In the present disclosure, terms such as “mobile station (MS)”, “user terminal (UE)”, and “terminal” may be used interchangeably.

[0292] For a mobile station, those skilled in the art sometimes also use the following terms to refer to it: subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, handset, user agent, mobile client, client, or some other appropriate terms.

[0293] At least one of the base station and the mobile station may also be referred to as a transmitting device, a receiving device, a communication device, etc. Furthermore, at least one of the base station and the mobile station may also be a device mounted on a mobile object, the mobile object itself, etc. The mobile object is an object that can move, and the moving speed can be arbitrary. This also includes situations where the mobile object is stationary. Examples of mobile objects include, but are not limited to, vehicles, transport vehicles, automobiles, motorcycles, bicycles, connected cars, excavators, bulldozers, wheel loaders, dump trucks, forklifts, trains, buses, rear vehicles, rickshaws, ships and other watercraft, airplanes, rockets, satellites, drones (registered trademark), multi-rotor helicopters, quadcopters, balloons, and objects mounted thereon. Furthermore, the mobile object may be one that moves autonomously based on operating commands. It may be a vehicle (such as a car or airplane), an unmanned mobile object (such as a drone or self-driving car), or a robot (manned or unmanned). Furthermore, at least one of the base station and the mobile station also includes devices that do not necessarily move during communication. For example, at least one of the base station and the mobile station may be an IoT (Internet of Things) device such as a sensor.

[0294] Furthermore, the base stations in this disclosure may be replaced with terminals. For example, a configuration in which communication between a base station and a terminal is replaced with communication between multiple terminals 20 (e.g., D2D (Device-to-Device) or V2X (Vehicle-to-Everything)) may also apply to the various forms / implementations of this disclosure. In this case, the terminal 20 may also have the functions of the base station 10 described above. Furthermore, terms such as "uplink" and "downlink" may be replaced with terms corresponding to inter-terminal communication (e.g., "side"). For example, terms such as uplink channel and downlink channel may be replaced with side channels.

[0295] Likewise, the terminal in the present disclosure may be replaced by a base station. In this case, the base station may also have the functions of the terminal.

[0296] As used in this disclosure, terms such as “determining” and “determining” sometimes encompass a variety of actions. For example, “determining” and “determining” may include considering as “judging” or “determining” any action involving the performance of judgment, calculation, computation, processing, deriving, investigating, searching (e.g., searching within a table, database, or other data structure), or ascertaining. Furthermore, “determining” and “determining” may include considering as “judging” or “determining” any action involving receiving (e.g., receiving information), transmitting (e.g., sending information), inputting, outputting, or accessing (e.g., accessing data in a memory). Furthermore, “determining” and “determining” may include considering as “judging” or “determining” any action involving resolving, selecting, choosing, establishing, or comparing. That is, “judgment” and “decision” can include actions that are considered to have been “judged” or “decided.” Furthermore, “judgment” (decision) can be replaced with “assuming,” “expecting,” “considering,” and so on.

[0297] The terms “connected”, “coupled” or any variation of these terms are intended to indicate any direct or indirect connection or combination between two or more elements, and may include situations where there is one or more intermediate elements between the two elements that are “connected” or “coupled” to each other. The combination or connection between elements may be a physical combination or connection, a logical combination or connection, or a combination of these. For example, “access” may be used instead of “connection”. As used in this disclosure, two elements may be considered to be “connected” or “coupled” to each other using at least one of one or more wires, cables and printed electrical connections, and as some non-limiting and non-inclusive examples, electromagnetic energy having wavelengths in the wireless frequency domain, microwave region and light (including both visible and invisible) region may be used to “connect” or “couple” to each other.

[0298] The reference signal may be referred to as RS (Reference Signal) for short, or may be called a pilot signal depending on the applicable standard.

[0299] The phrase “based on” used in this disclosure does not mean “based only on” unless explicitly stated otherwise. In other words, the phrase “based on” means both “based only on” and “based at least on.”

[0300] Any reference to an element using the terms "first," "second," etc., as used in this disclosure, does not necessarily limit the number or order of these elements. These terms may be used in this disclosure as a convenient way to distinguish between two or more elements. Therefore, a reference to a first element and a second element does not mean that only two elements can be used or that the first element must precede the second element in any form.

[0301] The “unit” in the configuration of each of the above-mentioned devices may be replaced with a “section,” “circuit,” “device,” or the like.

[0302] When the terms "include," "including," and variations thereof are used in this disclosure, these terms, like the term "comprising," are intended to be inclusive. Furthermore, the term "or" used in this disclosure does not mean an exclusive or.

[0303] A radio frame can be composed of one or more frames in the time domain. In the time domain, one or more frames can be called a subframe. A subframe can also be composed of one or more time slots in the time domain. A subframe can be of a fixed duration (e.g., 1 ms) independent of numerology.

[0304] A parameter set may be a communication parameter applied to at least one of the transmission and reception of a signal or channel. For example, a parameter set may represent at least one of the following: subcarrier spacing (SCS), bandwidth, symbol length, cyclic prefix length, transmission time interval (TTI), number of symbols per TTI, radio frame structure, specific filtering performed by the transceiver in the frequency domain, and specific windowing performed by the transceiver in the time domain.

[0305] A slot may be composed of one or more symbols (OFDM (Orthogonal Frequency Division Multiplexing) symbols, SC-FDMA (Single Carrier Frequency Division Multiple Access) symbols, etc.) in the time domain. A slot may be a time unit based on a parameter set.

[0306] A slot can contain multiple mini-slots. Each mini-slot can consist of one or more symbols in the time domain. Furthermore, a mini-slot can also be referred to as a sub-slot. A mini-slot can consist of fewer symbols than a slot. A PDSCH (or PUSCH) transmitted in time units larger than a mini-slot is referred to as PDSCH (or PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using a mini-slot is referred to as PDSCH (or PUSCH) mapping type B.

[0307] Radio frame, subframe, time slot, mini-time slot, and symbol all represent time units for signal transmission. Radio frame, subframe, time slot, mini-time slot, and symbol may be referred to by other corresponding names.

[0308] For example, a subframe can be called a Transmission Time Interval (TTI), multiple consecutive subframes can be called a TTI, and a time slot or a mini-time slot can also be called a TTI. That is, at least one of a subframe and a TTI can be a subframe (1ms) in existing LTE, a period shorter than 1ms (for example, 1-13 symbols), or a period longer than 1ms. Furthermore, the unit representing a TTI can be called a time slot, a mini-time slot, or something similar, rather than a subframe. Furthermore, a time slot can also be called a unit time. The unit time can vary for each cell, depending on the parameter set.

[0309] Here, TTI refers to, for example, the minimum time unit for scheduling in wireless communications. For example, in the LTE system, a base station schedules the allocation of wireless resources (such as the frequency bandwidth and transmit power available to each terminal 20) to each terminal 20 using TTIs as units. The definition of TTI is not limited to this.

[0310] A TTI can be a unit of time for transmitting data packets (transport blocks), code blocks, code words, etc. after channel coding, or a unit of processing for scheduling, link adaptation, etc. Furthermore, when a TTI is given, the time interval (e.g., the number of symbols) to which a transport block, code block, code word, etc. is actually mapped can be shorter than the TTI.

[0311] Furthermore, when one slot or one mini-slot is referred to as a TTI, one or more TTIs (i.e., one or more slots or one or more mini-slots) can be the minimum time unit for scheduling. Furthermore, the number of slots (mini-slots) that constitute this minimum time unit for scheduling can be controlled.

[0312] A TTI with a time length of 1 ms may also be referred to as a normal TTI (TTI in LTE Rel. 8-12), a normal TTI, a long TTI, a normal subframe, a normal subframe, a long subframe, a time slot, etc. A TTI shorter than a normal TTI may also be referred to as a shortened TTI, a short TTI, a partial or fractional TTI, a shortened subframe, a short subframe, a minislot, a subslot, a time slot, etc.

[0313] In addition, a long TTI (e.g., a normal TTI, a subframe, etc.) can be replaced with a TTI having a time length exceeding 1 ms, and a short TTI (e.g., a shortened TTI, etc.) can be replaced with a TTI having a TTI length that is smaller than the long TTI and greater than 1 ms.

[0314] A resource block (RB) is a unit of resource allocation in the time and frequency domains. In the frequency domain, it can contain one or more contiguous subcarriers. The number of subcarriers contained in an RB can be the same regardless of the parameter set, for example, it can be 12. The number of subcarriers contained in an RB can also be determined based on the parameter set.

[0315] In addition, the time domain of an RB may include one or more symbols and may be the length of one slot, one mini-slot, one subframe, or one TTI. One TTI, one subframe, etc. may each be composed of one or more resource blocks.

[0316] In addition, one or more RBs may also be referred to as a physical resource block (PRB: Physical RB), a sub-carrier group (SCG: Sub-Carrier Group), a resource element group (REG: Resource Element Group), a PRB pair, an RB pair, etc.

[0317] 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.

[0318] A bandwidth part (BWP) (also known as a fractional bandwidth) can also represent a subset of contiguous common resource blocks (RBs) used for a particular parameter set within a carrier. Common RBs can be identified by their index relative to the common reference point for that carrier. PRBs can be defined within a BWP and numbered within that BWP.

[0319] The BWP may include a UL BWP and a DL BWP. One or more BWPs may be configured for a UE within one carrier.

[0320] At least one of the configured BWPs may be active, and the UE may not assume that it will transmit or receive predetermined signals / channels outside the activated BWP. In addition, "cell", "carrier", etc. in the present disclosure may be replaced with "BWP".

[0321] The above-described structures of radio frames, subframes, slots, mini-slots, and symbols are merely examples. For example, various modifications may be made to the structures, such as the number of subframes in a radio frame, the number of slots per subframe or radio frame, the number of mini-slots within a slot, the number of symbols and RBs within a slot or mini-slot, the number of subcarriers within an RB, the number of symbols within a TTI, the symbol length, and the cyclic prefix (CP) length.

[0322] In the present disclosure, when an article is added by translation, such as a, an, and the in English, the present disclosure also includes cases where the noun following the article is in a plural form.

[0323] In this disclosure, the phrase "A and B are different" can mean "A and B are different from each other." Alternatively, the phrase can mean "A and B are each different from C." Terms such as "separate" and "combined" can also be interpreted in the same way as "different."

[0324] The various forms / implementations described in this disclosure may be used individually or in combination, and may be switched between them depending on the implementation. Furthermore, notification of predetermined information (e.g., notification of "Yes X") is not limited to being explicit, but may also be implicit (e.g., not notifying the predetermined information).

[0325] While the present disclosure has been described in detail above, it should be clear to those skilled in the art that the present disclosure is not limited to the embodiments described herein. The present disclosure can be implemented in various modifications and variations without departing from the spirit and scope of the present disclosure as defined by the claims. Therefore, the description of the present disclosure is for illustrative purposes only and does not have any limiting meaning on the present disclosure.
