[0023] The present invention described herein may be applied to or implemented in the exemplary wireless communication systems and devices described below. In addition, the present invention is mainly described in the context of the 3GPP architecture reference model. However, it should be understood that with the help of the disclosed information, those skilled in the art can easily adapt and use and implement aspects of the present invention in the 3GPP2 network architecture as well as other network architectures.

[0024] The exemplary wireless communication systems and devices described below employ wireless communication systems that support broadcast services. Wireless communication systems are widely deployed to provide various types of communications, such as voice, data, etc. These systems can be based on code division multiple access (CDMA), time division multiple access (TDMA), orthogonal frequency division multiple access (OFDMA), 3GPP Long Term Evolution (LTE) wireless access, 3GPP Long Term Evolution Advanced (LTE-A) wireless access, 3GPP2 Ultra Mobile Broadband (UMB), WiMax, 3GPP New Radio (NR), or some other modulation technology.

[0025] In particular, the exemplary wireless communication systems and devices described below may be designed to support one or more standards, such as those provided by a consortium named "3rd Generation Partnership Project" referred to herein as 3GPP, including: [1] RP-201256, "Solution for NR Support of Non-Terrestrial Networks (NTN)"; [2] 3GPP TS 38.331 V16.4.1, "NR, RRC Protocol Specification"; and [3] 3GPP TR 38.821 V16.0.0, "Solution for NR Support of Non-Terrestrial Networks (NTN)". The standards and documents listed above are hereby expressly and fully incorporated herein by reference in their entirety.

[0026] Figure 1 A multiple access wireless communication system according to an embodiment of the present invention is shown. Access network 100 (AN) includes multiple antenna groups, one including 104 and 106, another including 108 and 110, and another including 112 and 114. Figure 11, only two antennas are shown for each antenna group, however, each antenna group may utilize more or fewer antennas. Access terminal (AT) 116 communicates with antennas 112 and 114, where antennas 112 and 114 transmit information to access terminal 116 via forward link 120 and receive information from AT 116 via reverse link 118. AT 122 communicates with antennas 106 and 108, where antennas 106 and 108 transmit information to AT 122 via forward link 126 and receive information from AT 122 via reverse link 124. In an FDD system, communication links 118, 120, 124, and 126 may use different frequencies for communication. For example, forward link 120 may use a different frequency than the frequency used by reverse link 118.

[0027] Each group of antennas and / or the area in which they are designed to communicate is often referred to as a sector of the access network. In an embodiment, the antenna groups are each designed to communicate with access terminals in a sector of the area covered by the access network 100.

[0028] In communicating via forward links 120 and 126, the transmit antennas of access network 100 utilize beamforming in order to improve the signal-to-noise ratio of the forward links for the different access terminals 116 and 122. Additionally, an access network that transmits to access terminals randomly dispersed throughout its coverage area using beamforming causes less interference to access terminals in neighboring cells than an access network that transmits to all of its access terminals via a single antenna.

[0029] AN may be a fixed station or base station for communicating with a terminal, and may also be referred to as an access point, a Node B, a base station, an enhanced base station, an eNodeB, or some other term. AT may also be referred to as a user equipment (UE), a wireless communication device, a terminal, an access terminal, or some other term.

[0030] Figure 2 2 is a simplified block diagram of an embodiment of a transmitter system 210 (also referred to as an access network) and a receiver system 250 (also referred to as an access terminal (AT) or user equipment (UE)) in a MIMO system 200. At the transmitter system 210, traffic data for a number of data streams is provided from a data source 212 to a transmit (TX) data processor 214.

[0031] In one embodiment, each data stream is transmitted through a respective transmit antenna.TX data processor 214 formats, codes, and interleaves the traffic data for each data stream based on a particular coding scheme selected for that data stream to provide coded data.

[0032] The coded data for each data stream may be multiplexed with pilot data using OFDM techniques. The pilot data is typically a known data pattern that is processed in a known manner and may be used at the receiver system to estimate the channel response. The multiplexed pilot and coded data for each data stream is then modulated (e.g., symbol mapped) based on a particular modulation scheme (e.g., BPSK, QPSK, M-PSK, or M-QAM) selected for that data stream to provide modulation symbols. Instructions executed by processor 230 may determine the data rate, coding, and modulation for each data stream.

[0033] The modulation symbols for all data streams are then provided to a TX MIMO processor 220, which may further process the modulation symbols (e.g., for OFDM). The TX MIMO processor 220 then converts the N T The modulation symbol stream is provided to N T transmitters (TMTR) 222a through 222t. In certain embodiments, TX MIMO processor 220 applies beamforming weights to the symbols of the data streams and to the antenna from which the symbol is being transmitted.

[0034] Each transmitter 222 receives and processes a respective symbol stream to provide one or more analog signals, and further conditions (eg, amplifies, filters, and up-converts) the analog signals to provide a modulated signal suitable for transmission via a MIMO channel. T The antennas 224a to 224t transmit the N signals from the transmitters 222a to 222t. T a modulated signal.

[0035] At the receiver system 250, N R The transmitted modulated signals are received by each antenna 252a through 252r and the received signal from each antenna 252 is provided to a respective receiver (RCVR) 254a through 254r. Each receiver 254 conditions (e.g., filters, amplifies, and downconverts) a respective received signal, digitizes the conditioned signal to provide samples, and further processes the samples to provide a corresponding “received” symbol stream.

[0036] RX data processor 260 then extracts the N R The receiver 254 receives and processes N R received symbol streams to provide N TThe RX data processor 260 then demodulates, deinterleaves, and decodes each detected symbol stream to recover the traffic data for the data stream. The processing by the RX data processor 260 is complementary to the processing performed by the TX MIMO processor 220 and the TX data processor 214 at the transmitter system 210.

[0037] Processor 270 periodically determines which pre-coding matrix to use (discussed below). Processor 270 formulates a reverse link message comprising a matrix index portion and a rank value portion.

[0038] The reverse link message may include various types of information about the communication link and / or the received data stream. The reverse link message is then processed by the TX data processor 238 (which also receives traffic data for a number of data streams from the data source 236), modulated by the modulator 280, conditioned by the transmitters 254a to 254r, and transmitted back to the transmitter system 210.

[0039] At the transmitter system 210, the modulated signal from the receiver system 250 is received by the antenna 224, conditioned by the receiver 222, demodulated by the demodulator 240, and processed by the RX data processor 242 to extract the reverse link message transmitted by the receiver system 250. The processor 230 then determines which precoding matrix to use to determine the beamforming weights and then processes the extracted message.

[0040] The memory 232 may be used to temporarily store some buffer / calculated data from 240 or 242 via the processor 230, store some buffer data from 212, or store some specific program codes. Also, the memory 272 may be used to temporarily store some buffer / calculated data from 260 via the processor 270, store some buffer data from 236, or store some specific program codes.

Figure 3 As shown, the communication device 300 in the wireless communication system can be used to implement Figure 1UE (or AT) 116 and 122 in, and the wireless communication system is preferably an NR system. The communication device 300 may include an input device 302, an output device 304, a control circuit 306, a central processing unit (CPU) 308, a memory 310, a program code 312, and a transceiver 314. The control circuit 306 executes the program code 312 in the memory 310 through the CPU 308, thereby controlling the operation of the communication device 300. The communication device 300 can receive a signal input by a user through the input device 302 (e.g., a keyboard or a keypad), and can output images and sounds through the output device 304 (e.g., a monitor or a speaker). The transceiver 314 is used to receive and transmit wireless signals, pass the received signal to the control circuit 306, and wirelessly output the signal generated by the control circuit 306.

[0066] 5.5 Measurement

[0067] 5.5.1 Introduction

[0068] The network may configure an RRC_CONNECTED UE to perform measurements. The network may configure the UE to report them according to the measurement configuration, or perform a conditional reconfiguration evaluation according to a conditional reconfiguration. The measurement configuration is provided by means of dedicated signaling, i.e. using RRCReconfiguration or RRCResume.

[0069] The network may configure the UE to perform the following types of measurements:

[0070] -NR measurement;

[0071] - Inter-RAT measurements on E-UTRA frequencies.

[0072] - Inter-RAT measurements on UTRA-FDD frequencies.

[0073] The network may configure the UE to report the following measurement information based on SS / PBCH blocks:

[0074] -Measurement results per SS / PBCH block;

[0075] - Measurement results per cell based on SS / PBCH blocks;

[0076] -SS / PBCH block index.

[0077] The network may configure the UE to report the following measurement information based on the CSI-RS resource:

[0078] -Measurement results for each CSI-RS resource;

[0079] - Measurement results for each cell based on CSI-RS resources;

[0080] -CSI-RS resource measurement identifier.

[0081] The network may configure the UE to perform the following types of measurements for the sidelink:

[0082] -CBR measurement.

[0083] The network may configure the UE to report the following CLI measurement information based on SRS resources:

[0084] -Measurement results for each SRS resource;

[0085] -SRS resource index.

[0086] The network may configure the UE to report the following CLI measurement information based on the CLI-RSSI resource:

[0087] - Measurement results for each CLI-RSSI resource;

[0088] -CLI-RSSI resource index.

[0089] The measurement configuration contains the following parameters:

[0090] 1. Measurement objects: A list of objects on which the UE should perform measurements.

[0091] - For intra-frequency and inter-frequency measurements, the measurement object indicates the frequency / time position and subcarrier spacing of the reference signal to be measured. Associated with this measurement object, the network can configure a list of cell-specific offsets, a list of 'blacklist' cells and a list of 'whitelist' cells. Blacklist cells are not applicable in event evaluation or measurement reporting. Whitelist cells are the only cells that are applicable in event evaluation or measurement reporting.

[0092] -The measObjectId corresponding to the MO of each serving cell is indicated by servingCellMO in the serving cell configuration.

[0093] - For inter-RAT E-UTRA measurements, the measurement object is a single E-UTRA carrier frequency. Associated with this E-UTRA carrier frequency, the network can configure a list of cell-specific offsets, a list of 'whitelist' cells and a list of 'blacklist' cells. Blacklist cells are not applicable in event assessment or measurement reporting. Whitelist cells are the only cells that are applicable in event assessment or measurement reporting.

[0094] - For inter-RAT UTRA-FDD measurements, the measurement object is a group of cells on a single UTRA-FDD carrier frequency.

[0095] -CBR measurement for NR sidelink communication, the measurement object is a set of transmission resource pools on a single carrier frequency used for NR sidelink communication.

[0096] - For CLI measurement, the measurement object indicates the frequency / time location of the SRS resources and / or CLI-RSSI resources and the subcarrier spacing of the SRS resources to be measured.

[0097] 2. Report configuration: A list of report configurations, where each measurement object can have one or more report configurations. Each measurement report configuration consists of the following:

[0098] - Reporting Criteria: The criteria that triggers the UE to send a measurement report. This can be periodic or a single event description.

[0099] -RS type: RS (SS / PBCH block or CSI-RS) used by the UE for beam and cell measurement results.

[0100] - Reporting format: The per-cell and per-beam quantities (e.g. RSRP) that the UE includes in the measurement report along with other associated information, such as the maximum number of cells and the maximum number of beams per cell to be reported.

[0101] In the case of conditional reconfiguration, each configuration consists of:

[0102] - Execution Criteria: Criteria used by the UE for conditional reconfiguration execution.

[0103] - RS type: RS (SS / PBCH block based or CSI-RS based) used by the UE to obtain beam and cell measurement results for evaluating conditional reconfiguration execution conditions.

[0104] 3. Measurement identities: For measurement reporting, a list of measurement identities, where each measurement identity links one measurement object with one reporting configuration. By configuring multiple measurement identities, it is possible to link more than one measurement object to the same reporting configuration, and more than one reporting configuration to the same measurement object. The measurement identity is also included in the measurement report that triggers the report, acting as a reference to the network. For conditional reconfiguration triggering, one measurement identity is linked to exactly one conditional reconfiguration trigger configuration. And at most 2 measurement identities can be linked to one conditional reconfiguration execution condition.

[0105] 4. Quantity configuration: The quantity configuration defines the measurement filter configuration used for all event evaluations and related reporting, and for periodic reporting of the measurements. For NR measurements, the network can configure up to 2 quantity configurations through a reference to the configuration to be used in the NR measurement object. In each configuration, different filter coefficients can be configured for different measurement quantities, for different RS types, and for measurements per cell and per beam.

[0106] 5. Measurement gap: A period during which the UE can perform measurements.

[0107] A UE in RRC_CONNECTED maintains a list of measurement objects, a list of reporting configurations, and a list of measurement identities according to the signaling and procedures in this specification. The list of measurement objects may contain NR measurement objects, CLI measurement objects, and inter-RAT objects. Similarly, the list of reporting configurations contains NR and inter-RAT reporting configurations. Any measurement object may be linked to any reporting configuration of the same RAT type. Some reporting configurations may not be linked to measurement objects. Similarly, some measurement objects may not be linked to reporting configurations.

[0108] The measurement process distinguishes between the following types of cells:

[0109] 1. NR serving cells - these are the SpCell and one or more SCells.

[0110] 2. Listed cells - These are the cells listed within the measurement object.

[0111] 3. Detected cells - These are cells that are not listed within the measurement object but are detected by the UE on the SSB frequency and subcarrier spacing indicated by the measurement object.

[0112] For NR measurement objects, the UE measures and reports on the serving cell, listed cells and / or detected cells. For inter-RAT measurement objects for E-UTRA, the UE measures and reports on the listed cells and detected cells, and for RSSI and channel occupancy measurements, the UE measures and reports on the configured resources on the indicated frequency. For inter-RAT measurement objects for UTRA-FDD, the UE measures and reports on the listed cells. For CLI measurement objects, the UE measures and reports on the configured measurement resources (i.e., SRS resources and / or CLI-RSSI resources).

[0265] In the radio resource control (RRC)_CONNECTED state, the user equipment (UE) measures multiple beams (or at least one) of the cell to derive the cell quality relative to the synchronization signal block (SSB) and / or the channel state information reference signal (CSI-RS). And when a triggering event based on the measurement result (e.g., the criteria / condition for the triggering event) is met, the UE initiates a measurement reporting procedure to send the measurement result to the network (NW). The triggering event may have an entry condition and an exit or exit condition. If the entry condition and / or the exit condition for the triggering event are met, the UE may initiate the measurement reporting procedure. The triggering event may be that the radio condition of the serving cell and / or the neighboring cell becomes better / worse than a threshold. The threshold may be an absolute threshold and / or an offset. Details on measurement reporting may be found in TS 38.331 [2].

[0266] On the other hand, the non-terrestrial network (NTN) to be introduced in the new radio (NR) is to use air / space carrier work as a platform for providing mobile services (e.g., RP-201256 [1]). UE can be linked to, reside on and / or connected to the NTN network involving air / space transmission. NTN includes various platforms, including low earth orbit (LEO) satellites, medium earth orbit (MEO) satellites, high elliptical orbit (HEO) satellites, geostationary orbit (GEO) satellites, non-geostationary orbit (NGSO) satellites, and / or high altitude platforms (HAP). LEO satellites can have earth-fixed beams (e.g., beams are temporarily fixed at a position during a time period) or earth-mobile beams (e.g., beams move continuously together with the satellite). For more details about different NTN platforms, see TR 38.821 [3]. NTN can provide wide area coverage and provide NW access in scenarios when terrestrial networks (TN) are not feasible (e.g., deserts, polar regions and / or on airplanes). However, due to the longer distance between the UE and the satellite, there is a small difference / variation in radio conditions / signal strength between the cell edge and the cell center in the NTN compared to the TN (e.g., TR 38.821 [3]). The NTN UE may therefore have difficulty distinguishing whether to trigger a measurement report based on the measurement results as currently used in the TN (e.g., based on radio conditions such as Reference Signal Received Power (RSRP)).

[0267] In order to solve the problem, based on work item (WI) RP-201256 [1] and TR 38.821 [3], location information can be introduced in addition to measurement results for coverage management. At the 3GPP RAN2#112 electronic meeting, it was agreed that location-based measurement events should be supported in NTN in combination with existing measurement events in NR. Therefore, location-based trigger events combined with existing trigger events (based on radio conditions) can be defined for NTN. For example, an NTN UE can be configured to trigger a measurement report (or initiate a measurement report procedure) based on a combined trigger condition of a first trigger event and a second trigger event. The first trigger event can be based on a radio condition (e.g., Event A1, Event A2, Event A3, Event A4, Event A5, Event A6, CondEvent A3, and / or CondEvent A5 in TS 38.331 [2]). The second trigger event can be based on a location (e.g., the distance between the UE and a reference location such as a cell center). The UE can trigger a measurement report (or initiate a measurement report procedure) when the first trigger event and the second trigger event (e.g., the combined trigger condition) are met.

[0268] On the other hand, it may be possible that the UE is configured with a trigger event based on location alone (e.g., a second trigger event based on the distance between the UE and a reference location such as a cell center), for example, without being configured with a first trigger event. In this case, the UE may trigger a measurement report (or initiate a measurement reporting procedure) when the second trigger event is met (even if the first trigger event is not met).

[0269] It is assumed that the configuration of each event (e.g., the first or second triggering event) has its own associated parameters (e.g., timeToTrigger, reportOnLeave, useWhiteCellList). However, if the UE is configured to trigger a measurement report (or initiate a measurement reporting procedure) based on a combined triggering condition of more than one triggering event (e.g., the first triggering event and the second triggering event), it will be a problem what values ​​to use for the parameters corresponding to the combined triggering condition. If the measurement reporting procedure is associated with multiple triggering events and all events need to be satisfied at the same time, some parameters configured for each triggering event / in each triggering event may be repeated and cause confusion.

[0270] For example, there may be a first parameter (e.g., timeToTrigger) having a first value configured for a first trigger event / in the first trigger event and a first parameter having a second value configured for a second trigger event / in the second trigger event. The first parameter having the first value may specify the length of the duration that needs to be satisfied for the first trigger event in order to trigger a measurement report. The first parameter having the second value may specify the length of the duration that needs to be satisfied for the second trigger event in order to trigger a measurement report. The first value and the second value may be durations in milliseconds (ms). The first value may be different from the second value. When the first trigger event has been satisfied in the duration with the first value, the second trigger event may not be satisfied in the duration with the second value. When the second trigger event has been satisfied in the duration with the second value, the first trigger event may no longer be satisfied. Since the two trigger events are not satisfied in the same duration, the UE may not know whether to trigger a measurement report.

[0271] For example, there may be a second parameter (e.g., reportOnLeave) having a third value configured for / in a first trigger event and a second parameter having a fourth value configured for / in a second trigger event. The second parameter having the third value may indicate whether a measurement reporting procedure is initiated when a leaving condition in the first trigger event is met. The second parameter having the fourth value may indicate whether a measurement reporting procedure is initiated when a leaving condition in the second trigger event is met. The third value and the fourth value may be Boolean values.

[0272] The second parameter (e.g., reportOnLeave) may be processed separately with different values ​​for the first trigger event and the second trigger event. In one example, the UE is configured to trigger a measurement report based on a combined trigger condition of the first trigger event and the second trigger event, and the measurement report may be triggered when (or in response to) the entry condition of the first trigger event and the second trigger event has been met. If the second parameter (e.g., reportOnLeave) for the first trigger event and the second trigger event is set to true, the UE may trigger a measurement report when the exit condition of the first and second trigger events is met. However, if Figure 5 As shown, the UE may trigger a measurement report when the exit condition of the first trigger event is met at the first timing, and trigger another measurement report when the exit condition of the second trigger event is met at the second timing. The measurement reports triggered at both the first timing and the second timing are considered unnecessary because the NW may know that any one of the measurement reports has not met the combined trigger condition.

[0273] In another example, the UE is configured to trigger a measurement report based on a combined triggering condition of a first triggering event and a second triggering event, and the measurement report may be triggered when (or in response to) the entry conditions of the first triggering event and the second triggering event have been met. If the second parameter for the first triggering event (e.g., reportOnLeave) is set to true and the second parameter for the second triggering event is set to false, such as Figure 6 As shown, the UE may trigger a measurement report when the leaving condition of the first triggering event is met at the first timing, and may not trigger a measurement report when the leaving condition of the second triggering event is met at the second timing, whether the first timing or the second timing is earlier. However, the NW should be informed as soon as possible that the combined triggering condition has not been met. Otherwise, the prepared handover (or conditional handover) may not be suitable for the latest UE conditions.

[0274] In another example, the UE is configured to trigger a measurement report based on a combined trigger condition of a first trigger event and a second trigger event, and the entry conditions of the first and second trigger events have not been met (e.g., the entry condition of the first trigger event is met but the entry condition of the second trigger event has not been met), so the UE does not trigger a measurement report. Figure 7 As shown, if the second parameter (e.g., reportOnLeave) for one of the events (e.g., the first triggering event) is set to true, then the UE may trigger a measurement report when the exit condition of the first triggering event is met (the entry condition of the first triggering event may have been met). In this case, for example, the triggered measurement report seems unnecessary because it may not be beneficial for the NW to prepare (or update) candidate target cells.

[0275] When the UE is configured with two triggering events (e.g., a combined triggering condition) in the measurement configuration, the UE is expected to trigger a measurement report when both triggering events are met. However, if the third value is true and the fourth value is false, the UE may trigger a measurement report when only the leaving condition in the first triggering event is met. In this case, the second triggering event is not met when the UE reports the measurement result.

[0276] If the UE is configured to trigger a measurement report based on a combined triggering condition of the first triggering event and the second triggering event, and the second parameter for the combined triggering condition (e.g., reportOnLeave) is determined to be true (e.g., based on the method described below), then if the leaving condition of the first triggering event or the second triggering event has been met, the UE may trigger the measurement report. Once the measurement report is triggered due to one of the leaving conditions being met, if the leaving conditions of the first triggering event and the second triggering event have been met, the UE may not trigger the measurement report (e.g., Figure 8 Alternatively, if the exit conditions of the first trigger event and the second trigger event are met, the UE may trigger a measurement report (eg, Figure 6 If the leaving condition of one of the events is met, then measurement reporting may not be triggered.

[0277] Furthermore, for the combined triggering condition, if the measurement report has not been triggered due to satisfying the entry condition, the UE does not trigger the measurement report due to satisfying the leaving condition (even if reportOnLeave is set to true).

[0278] For example, there may be a third parameter (e.g., useWhiteCellList) having a fifth value configured for a first trigger event / in a first trigger event and a third parameter having a sixth value configured for a second trigger event / in a second trigger event. The third parameter having a fifth value may indicate whether only neighboring cells included in the whitelist are applicable to the first trigger event. The third parameter having a sixth value may indicate whether only neighboring cells included in the whitelist are applicable to the second trigger event. The fifth value and the sixth value may be Boolean values. If the fifth value and the sixth value are different, the UE may consider the first trigger event and the second trigger event for different groups of neighboring cells. However, the two trigger events need to be met on the same cell (e.g., a neighboring cell) to trigger a measurement report. Once one of the values ​​of the third parameter is true, the UE may report measurement results only for neighboring cells included in the whitelist. If the fifth value is true and the sixth value is false, it is inefficient for the UE to check the second trigger event on a neighboring cell not included in the whitelist.

[0279] Therefore, when the measurement reporting procedure is associated with multiple triggering events, the UE needs to know how to determine (the values ​​of) the first, second and / or third parameters.

[0280] To solve the problem, the NW may configure the same value for the parameters in the trigger event / used for the trigger event in the measurement configuration. For example, if the NW configures the UE to trigger a measurement report (or initiate a measurement report procedure) based on a combined trigger condition (e.g., a first trigger event and a second trigger event), then at least the parameters of all trigger events associated with the combined trigger condition (e.g., the parameters of the first trigger event and the parameters of the second trigger event) need to be configured to have the same value. For example, if the NW configures the UE to trigger a measurement report (or initiate a measurement report procedure) based on a combined trigger condition (e.g., a first trigger event and a second trigger event), then at least the parameters of all trigger events associated with the combined trigger condition (e.g., the parameters of the first trigger event and the parameters of the second trigger event) are not allowed to be configured to have different values. The parameter may be timeToTrigger. The parameter may be reportOnLeave. The parameter may be useWhiteCellList.

[0281] When all trigger events associated with the combined trigger condition (e.g., the first trigger event and the second trigger event) are met (or in response thereto), the UE may initiate a measurement reporting procedure. The NW may configure the first parameter (e.g., timeToTrigger) in / for the trigger event (e.g., the first trigger event and the second trigger event) with the same length of duration. The NW may configure the second parameter (e.g., reportOnLeave) in / for the trigger event (e.g., the first trigger event and the second trigger event) with the same Boolean value. The NW may configure the third parameter (e.g., useWhiteCellList) in / for the trigger event (e.g., the first trigger event and the second trigger event) with the same Boolean value. The trigger events (e.g., the first trigger event and the second trigger event) configured in the measurement configuration may be trigger events based on cell quality (e.g., RSRP / reference signal received quality (RSRQ) / signal to interference and noise ratio (SINR) of the cell) and / or based on UE location (e.g., the distance between the UE and a reference location such as the cell center). The UE may be configured to trigger a measurement report (or initiate a measurement reporting procedure) based on a combined triggering condition of multiple triggering events (e.g., a first triggering event and a second triggering event). Triggering events (e.g., a first triggering event and a second triggering event) that need to have the same value for a parameter (e.g., timeToTrigger, reportOnleave, useWhileCellList) may be associated with a combined triggering condition.

[0282] The UE may not be configured to trigger (or initiate) a measurement report based solely on the first triggering event. The UE may not be configured to trigger (or initiate) a measurement report based solely on the second triggering event. If (or in response to) a triggering condition (e.g., entry condition) associated with the first triggering event is met but a triggering condition (e.g., entry condition) associated with the second triggering event is not met, then the UE may not trigger (or initiate) a measurement report. If (or in response to) a triggering condition (e.g., entry condition) associated with the second triggering event is met but a triggering condition (e.g., entry condition) associated with the first triggering event is not met, then the UE may not trigger (or initiate) a measurement report.

[0283] For example, the NW may configure a first trigger event based on cell quality and a second trigger event based on UE location as a combined trigger condition. The NW may configure a first parameter (e.g., timeToTrigger) with the same value in / for the first trigger event and the second trigger event. When both the first trigger event and the second trigger event are met in the duration with the value in the first parameter (or in response thereto), the UE may initiate a measurement report procedure. The NW may configure a second parameter (e.g., reportOnLeave) as true in / for the first trigger event and the second trigger event. When the leaving condition in both the first trigger event and the second trigger event is met (or in response thereto), the UE may initiate a measurement report procedure. When the leaving condition in one of the first trigger event and the second trigger event is met (or in response thereto), the UE may initiate a measurement report procedure. The NW may configure a second parameter (e.g., reportOnLeave) as false in / for the first trigger event and the second trigger event. When any one of the leaving conditions in the first trigger event and the second trigger event is met (or in response thereto), the UE may not initiate a measurement report procedure. The NW may configure the third parameter (e.g., useWhiteCellList) as true in / for the first trigger event and the second trigger event. The UE may check the first trigger event and the second trigger event on the neighboring cells included in the whitelist. The NW may configure the third parameter (e.g., useWhiteCellList) as false in / for the first trigger event and the second trigger event. The UE may check the first trigger event and the second trigger event on all neighboring cells.

[0284] To solve the problem, in the measurement configuration, the NW may configure the parameter in / for one of the triggering events and not in / for the other triggering events. For example, the parameter may be associated with one of the triggering events (e.g., a triggering event based on cell quality) but not with the other triggering events (e.g., a triggering event based on UE location). For example, Fig. 9 As shown in the configuration procedure 500, the NW may configure parameters in / for trigger events based on cell quality (e.g., eventA3, eventA4, and / or eventA5), and not configure the parameters in / for trigger events based on UE location (e.g., eventL1 and / or eventL2). Not configuring a parameter may mean that the parameter cannot be configured (e.g., the parameter does not exist in the configuration). When all trigger events associated with a combined trigger condition (e.g., a first trigger event and a second trigger event) are met (or in response thereto), the UE may initiate a measurement reporting procedure. The parameter may be a first parameter (e.g., timeToTrigger), a second parameter (e.g., reportOnLeave), and / or a third parameter (e.g., useWhiteCellList). The trigger events configured in the measurement configuration may be trigger events based on cell quality (e.g., RSRP / RSRQ / SINR of a cell) and / or based on UE location (e.g., the distance between the UE and a reference location such as a cell center). The UE may be configured to trigger a measurement report (or initiate a measurement reporting procedure) based on a combined triggering condition of a plurality of triggering events (eg, a first triggering event and a second triggering event).

[0285] The UE may not be configured to trigger (or initiate) a measurement report based solely on the first triggering event. The UE may not be configured to trigger (or initiate) a measurement report based solely on the second triggering event. If (or in response to) a triggering condition (e.g., entry condition) associated with the first triggering event is met but a triggering condition (e.g., entry condition) associated with the second triggering event is not met, then the UE may not trigger (or initiate) a measurement report. If (or in response to) a triggering condition (e.g., entry condition) associated with the second triggering event is met but a triggering condition (e.g., entry condition) associated with the first triggering event is not met, then the UE may not trigger (or initiate) a measurement report.

[0286] For example, the NW may configure a first trigger event based on cell quality and a second trigger event based on UE location as a combined trigger condition. The NW may configure a second parameter (e.g., reportOnLeave) as true in the first trigger event / for the first trigger event, and may not configure another second parameter (e.g., reportOnLeave) in the second trigger event / for the second trigger event. When the leaving condition in both the first trigger event and the second trigger event (or in response thereto) is met, the UE may initiate a measurement report procedure. When the leaving condition in one of the first trigger event and the second trigger event (or in response thereto) is met, the UE may initiate a measurement report procedure. The UE may consider the second parameter (e.g., reportOnLeave) as true in the second trigger event and / or the combined trigger condition. When any one of the leaving conditions in the first trigger event and the second trigger event (or in response thereto) is met, the UE may not initiate a measurement report procedure. The UE may consider the second parameter (e.g., reportOnLeave) as false in the second trigger event and / or the combined trigger condition / for the second trigger event and / or the combined trigger condition. The NW may configure the second parameter (e.g., reportOnLeave) to false in / for the first trigger event and the second trigger event. When any of the leaving conditions in the first trigger event and the second trigger event is met (or in response thereto), the UE may not initiate a measurement reporting procedure.

[0287] In one example, the NW may configure the parameter in / for one of the triggering events. The NW may not configure the parameter in / for more than one triggering event.

[0288] For example, again Fig. 9As shown, the NW can configure a first trigger event based on cell quality (e.g., eventA4) and a second trigger event based on UE location (e.g., eventL1) as a combined trigger condition. The NW can configure a first parameter (e.g., timeToTrigger), a second parameter (e.g., reportOnLeave) and / or a third parameter (e.g., useWhiteCellList) in / for the first trigger event (e.g., eventA4). The NW may not configure the above parameters in / for the second trigger event in the second trigger event (e.g., eventL1). The NW may configure the first trigger event in the first event identity (ID) (e.g., eventId) and the second trigger event in the second event ID (e.g., eventId-Loc). The NW may configure the first event ID and the second event ID in the event trigger configuration (e.g., EventTriggerConfig) in the measurement configuration. The second event ID may be optional. When the combined trigger condition is configured (or in response thereto), the second event ID may exist. When the combined trigger condition is not configured (or in response thereto), the second event ID may not exist. When (or in response to) both the first triggering event and the second triggering event (eg, a combined triggering condition) are satisfied, the UE may initiate a measurement reporting procedure.

[0289] In another example, the NW may configure a parameter as optional in / for a triggering event. The NW may configure a parameter as non-optional in / for one of the triggering events and as optional in / for other triggering events. The NW may configure a parameter as optional in / for all triggering events. The NW may not configure a parameter as non-optional in / for all triggering events. In a measurement configuration, a parameter in / for one of the triggering events may be present, while a parameter in / for other triggering events may not be present.

[0290] For example, if Fig.10 and Fig.11As shown in configuration procedures 600 and 700, respectively, the NW can configure a first trigger event based on cell quality (e.g., eventA4) and a second trigger event based on UE location (e.g., eventL1) as a combined trigger condition. The NW can configure a first parameter (e.g., timeToTrigger), a second parameter (e.g., reportOnLeave) and / or a third parameter (e.g., useWhiteCellList) in / for the first trigger event (e.g., eventA4) and the second trigger event (e.g., eventL1). If the first, second and / or third parameters exist and / or are configured in the first trigger event (e.g., eventA4), the above parameters in the second trigger event (e.g., eventL1) may not exist. If the first, second and / or third parameters do not exist and / or are configured in the first trigger event (e.g., eventA4), the above parameters in the second trigger event may exist (e.g., eventL1). If the first, second and / or third parameters are present (and / or configured) in the second trigger event (e.g., eventL1), then the first, second and / or third parameters in the first trigger event (e.g., eventA4) may not be present. If the first, second and / or third parameters are not present (and / or configured) in the second trigger event (e.g., eventL1), then the first, second and / or third parameters in the first trigger event may be present (e.g., eventA4). When both the first trigger event and the second trigger event are met (or in response thereto), the UE may initiate a measurement reporting procedure.

[0291] like Fig.10 As shown in configuration procedure 600, the NW may configure a first trigger event in a first event ID (e.g., eventId) and a second trigger event in a second event ID (e.g., eventId-Loc). The NW may configure the first event ID and the second event ID in an event trigger configuration (e.g., EventTriggerConfig) in a measurement configuration. The first event ID and the second event ID may be optional. When a combined trigger condition is configured (or in response thereto), both the first event ID and the second event ID may exist. When a combined trigger condition is not configured (or in response thereto), one of the first event ID and the second event ID may not exist.

[0292] like Fig.11 The NW may configure the first trigger event and the second trigger event in a first event ID (eg, eventld), shown as configuration procedure 700. The NW may configure a list of first event IDs in an event trigger configuration (eg, EventTriggerConfig) in a measurement configuration.

[0293] To solve the problem, the NW can configure parameters in the measurement configuration for all trigger events. For example, Fig.12 As shown in configuration procedure 800, the NW may configure parameters in an event trigger configuration (e.g., EventTriggerConfig) in a measurement configuration (e.g., for a combined trigger condition). The NW may configure trigger events (e.g., eventA3, eventA4, eventA5, eventL1, eventL2) in the event trigger configuration. The NW may not configure parameters individually in / for each trigger event (e.g., eventA3, eventA4, eventA5, eventL1, eventL2). The parameters may be applied to all trigger events (e.g., of a combined trigger condition) in common. The parameters may not be specific to a specific trigger event (e.g., of a combined trigger condition). When all trigger events associated with a combined trigger condition (e.g., a first trigger event and a second trigger event) are met (or in response thereto), the UE may initiate a measurement reporting procedure. The parameters may be a first parameter (e.g., timeToTrigger), a second parameter (e.g., reportOnLeave), and / or a third parameter (e.g., useWhiteCellList). The trigger event configured in the measurement configuration may be a trigger event based on cell quality (e.g., RSRP / RSRQ / SINR of the cell) and / or based on UE location (e.g., the distance between the UE and a reference location such as the cell center). The UE may be configured to trigger a measurement report (or initiate a measurement reporting procedure) based on a combined trigger condition of multiple trigger events (e.g., a first trigger event and a second trigger event).

[0294] The UE may not be configured to trigger (or initiate) a measurement report based solely on the first triggering event. The UE may not be configured to trigger (or initiate) a measurement report based solely on the second triggering event. If (or in response to) a triggering condition (e.g., entry condition) associated with the first triggering event is met but a triggering condition (e.g., entry condition) associated with the second triggering event is not met, then the UE may not trigger (or initiate) a measurement report. If (or in response to) a triggering condition (e.g., entry condition) associated with the second triggering event is met but a triggering condition (e.g., entry condition) associated with the first triggering event is not met, then the UE may not trigger (or initiate) a measurement report.

[0295] For example, the NW may configure a first trigger event based on cell quality (e.g., eventA4) and a second trigger event based on UE location (e.g., eventL1) in the event ID list in the event trigger configuration (e.g., EventTriggerConfig) in the measurement configuration as a combined trigger condition. The NW may configure a first parameter (e.g., timeToTrigger), a second parameter (e.g., reportOnLeave), and / or a third parameter (e.g., useWhiteCellList) in the event trigger configuration (e.g., EventTriggerConfig). The NW may not configure the above parameters separately in the first trigger event and / or the second trigger event / for the first trigger event and / or the second trigger event in the event ID (e.g., eventId) (e.g., for a combined trigger condition). When both the first trigger event and the second trigger event are met (or in response thereto), the UE may initiate a measurement reporting procedure.

[0296] For example, the NW may configure a first trigger event based on cell quality and a second trigger event based on UE location as a combined trigger condition in an event trigger configuration (e.g., EventTriggerConfig). The NW may configure a second parameter (e.g., reportOnLeave) as true in the event trigger configuration (e.g., EventTriggerConfig). When the leaving condition in both the first trigger event and the second trigger event is met (or in response thereto), the UE may initiate a measurement reporting procedure. When the leaving condition in one of the first trigger event and the second trigger event is met (or in response thereto), the UE may initiate a measurement reporting procedure. The NW may configure a second parameter (e.g., reportOnLeave) as false in the event trigger configuration (e.g., EventTriggerConfig). When either of the leaving conditions in the first trigger event and the second trigger event is met (or in response thereto), the UE may not initiate a measurement reporting procedure.

[0297] To solve the problem, the UE can select the shortest value of the parameter in / for the trigger event. The parameter can be a first parameter (e.g., timeToTrigger). The trigger event is configured as a combined trigger condition in the measurement configuration. When all trigger events associated with the combined trigger condition (e.g., the first trigger event and the second trigger event) are met (or in response thereto), the UE can initiate a measurement reporting procedure. The trigger event configured in the measurement configuration can be a trigger event based on cell quality (e.g., RSRP / RSRQ / SINR of the cell) and / or based on the UE location (e.g., the distance between the UE and a reference location such as the cell center). The UE can be configured to trigger a measurement report (or initiate a measurement reporting procedure) based on a combined trigger condition of multiple trigger events (e.g., the first trigger event and the second trigger event).

[0298] The UE may not be configured to trigger (or initiate) a measurement report based solely on the first triggering event. The UE may not be configured to trigger (or initiate) a measurement report based solely on the second triggering event. If (or in response to) a triggering condition (e.g., entry condition) associated with the first triggering event is met but a triggering condition (e.g., entry condition) associated with the second triggering event is not met, then the UE may not trigger (or initiate) a measurement report. If (or in response to) a triggering condition (e.g., entry condition) associated with the second triggering event is met but a triggering condition (e.g., entry condition) associated with the first triggering event is not met, then the UE may not trigger (or initiate) a measurement report.

[0299] For example, the NW may configure a first trigger event based on cell quality and a second trigger event based on UE location as a combined trigger condition. The NW may configure a first parameter (e.g., timeToTrigger) in the first trigger event and the second trigger event. The value of the first parameter in the first trigger event may be shorter than the value in the second trigger event. When both the first trigger event and the second trigger event are met (or in response thereto) in the duration having the value of the first parameter in the first trigger event, the UE may initiate a measurement report procedure.

[0300] To solve the problem, the UE can select the longest value of the parameter in / for the trigger event. The parameter can be a first parameter (e.g., timeToTrigger). The trigger event is configured as a combined trigger condition in the measurement configuration. When all trigger events associated with the combined trigger condition (e.g., the first trigger event and the second trigger event) are met (or in response thereto), the UE can initiate a measurement reporting procedure. The trigger event configured in the measurement configuration may be a trigger event based on cell quality (e.g., RSRP / RSRQ / SINR of the cell) and / or based on UE location (e.g., the distance between the UE and a reference location such as the cell center). The UE can be configured to trigger a measurement report (or initiate a measurement reporting procedure) based on a combined trigger condition of multiple trigger events (e.g., the first trigger event and the second trigger event).

[0301] For example, the NW may configure a first trigger event based on cell quality and a second trigger event based on UE location as a combined trigger condition. The NW may configure a first parameter (e.g., timeToTrigger) in the first trigger event and the second trigger event. The value of the first parameter in the second trigger event may be longer than the value in the first trigger event. When both the first trigger event and the second trigger event are met (or in response thereto) in the duration having the value of the first parameter in the second trigger event, the UE may initiate a measurement report procedure.

[0302] To solve the problem, if one of the values ​​of the parameters in the trigger event / used for the trigger event is true, the UE may regard the value of the parameter as true. If all the values ​​of the parameters in the trigger event / used for the trigger event are false, the UE may regard the value of the parameter as false. It may be applicable to the case where only one trigger event is configured with a parameter among the combined trigger events (for example, the other trigger events are not configured with a parameter). The trigger event is configured as a combined trigger condition in the measurement configuration. When all the trigger events associated with the combined trigger condition (for example, the first trigger event and the second trigger event) are met (or in response thereto), the UE may initiate a measurement reporting procedure. The parameter may be a second parameter (for example, reportOnLeave) and / or a third parameter (for example, useWhiteCellList). The trigger event configured in the measurement configuration may be a trigger event based on cell quality (for example, RSRP / RSRQ / SINR of a cell) and / or based on UE location (for example, the distance between the UE and a reference location such as a cell center). The UE may be configured to trigger a measurement report (or initiate a measurement reporting procedure) based on a combined trigger condition of multiple trigger events (for example, the first trigger event and the second trigger event).

[0303] The UE may not be configured to trigger (or initiate) a measurement report based solely on the first triggering event. The UE may not be configured to trigger (or initiate) a measurement report based solely on the second triggering event. If (or in response to) a triggering condition (e.g., an entry condition) associated with the first triggering event is met but a triggering condition (e.g., an entry condition) associated with the second triggering event is not met, then the UE may not trigger (or initiate) a measurement report. If (or in response to) a triggering condition (e.g., an entry condition) associated with the second triggering event is met but a triggering condition (e.g., a condition) associated with the first triggering event is not met, then the UE may not trigger (or initiate) a measurement report.

[0304] For example, the NW may configure a first trigger event based on cell quality and a second trigger event based on UE location as a combined trigger condition. The NW may configure a second parameter (e.g., reportOnLeave) in / for the first trigger event and the second trigger event. If one of the values ​​of the second parameter in / for the two trigger events is true, the UE may trigger a measurement report when the leaving condition in the first trigger event and the second trigger event is met (or in response thereto). If one of the values ​​of the second parameter in / for the two trigger events is true, the UE may trigger a measurement report when one of the leaving conditions in the first trigger event and the second trigger event is met (or in response thereto). If both values ​​of the second parameter in / for the two trigger events are false, the UE may not trigger a measurement report when the leaving condition in the first trigger event and / or the second trigger event is met (or in response thereto).

[0305] For example, the NW may configure a first trigger event based on cell quality and a second trigger event based on UE location as a combined trigger condition. The NW may configure a third parameter (e.g., useWhiteCellList) in / for the first trigger event and the second trigger event. If both values ​​of the third parameter in / for the two trigger events are false, the UE may check the first trigger event and the second trigger event on all neighboring cells. If one of the values ​​of the third parameter in / for the two trigger events is true, the UE may check the first trigger event and the second trigger event on neighboring cells included in the whitelist.

[0306] To solve the problem, if one of the values ​​of the parameters in the trigger event / used for the trigger event is false, the UE may regard the value of the parameter as false. If all the values ​​of the parameters in the trigger event / used for the trigger event are true, the UE may regard the value of the parameter as true. It may be applicable to the case where only one trigger event is configured with a parameter among the combined trigger events (for example, the other trigger events are not configured with a parameter). The trigger event is configured as a combined trigger condition in the measurement configuration. When all the trigger events associated with the combined trigger condition (for example, the first trigger event and the second trigger event) are met (or in response thereto), the UE may initiate a measurement reporting procedure. The parameter may be a second parameter (for example, reportOnLeave) and / or a third parameter (for example, useWhiteCellList). The trigger event configured in the measurement configuration may be a trigger event based on cell quality (for example, RSRP / RSRQ / SINR of a cell) and / or based on UE location (for example, the distance between the UE and a reference location such as a cell center). The UE may be configured to trigger a measurement report (or initiate a measurement reporting procedure) based on a combined trigger condition of multiple trigger events (for example, the first trigger event and the second trigger event).

[0307] The UE may not be configured to trigger (or initiate) a measurement report based solely on the first triggering event. The UE may not be configured to trigger (or initiate) a measurement report based solely on the second triggering event. If (or in response to) a triggering condition (e.g., entry condition) associated with the first triggering event is met but a triggering condition (e.g., entry condition) associated with the second triggering event is not met, then the UE may not trigger (or initiate) a measurement report. If (or in response to) a triggering condition (e.g., entry condition) associated with the second triggering event is met but a triggering condition (e.g., entry condition) associated with the first triggering event is not met, then the UE may not trigger (or initiate) a measurement report.

[0308] For example, the NW may configure a first trigger event based on cell quality and a second trigger event based on UE location as a combined trigger condition. The NW may configure a second parameter (e.g., reportOnLeave) in / for the first trigger event and the second trigger event. If one of the values ​​of the second parameter in / for the two trigger events is false, the UE may not trigger a measurement report when the leaving condition in the first trigger event and / or the second trigger event is met (or in response thereto). If both values ​​of the second parameter in / for the two trigger events are true, the UE may trigger a measurement report when the leaving condition in the first trigger event and the second trigger event is met (or in response thereto). If both values ​​of the second parameter in / for the two trigger events are true, the UE may trigger a measurement report when the leaving condition in the first trigger event and the second trigger event is met (or in response thereto).

[0309] For example, the NW may configure a first trigger event based on cell quality and a second trigger event based on UE location as a combined trigger condition. The NW may configure a third parameter (e.g., useWhiteCellList) in / for the first trigger event and the second trigger event. If both values ​​of the third parameter in / for the two trigger events are true, the UE may check the first trigger event and the second trigger event on the neighboring cells included in the whitelist. If one of the values ​​of the third parameter in / for the two trigger events is false, the UE may check the first trigger event and the second trigger event on all neighboring cells.

[0310] To solve the problem, the UE may use a parameter (value) in a specific trigger event among the trigger events / for the specific trigger event. The trigger event is configured as a combined trigger condition in the measurement configuration. When all trigger events associated with the combined trigger condition (e.g., the first trigger event and the second trigger event) are met (or in response thereto), the UE may initiate a measurement report procedure. Parameters may be configured in / for the trigger event. The parameter may be a first parameter (e.g., timeToTrigger), a second parameter (e.g., reportOnLeave), and / or a third parameter (e.g., useWhiteCellList). The UE may use a parameter (value) in / for one of the trigger events. The UE may ignore parameters (values) in / for other trigger events. The trigger event configured in the measurement configuration may be a trigger event based on cell quality (e.g., RSRP / RSRQ / SINR of a cell) and / or based on UE location (e.g., the distance between the UE and a reference location such as a cell center). The UE may use a parameter (value) in / for a trigger event based on cell quality. The UE may use a parameter (value) in a trigger event based on the UE location / for a trigger event based on the UE location. The UE may use a parameter (value) in a trigger event based on measurement / for a trigger event based on measurement. The UE may use a parameter (value) in a trigger event based on location / for a trigger event based on location. The UE may use a parameter (value) in a trigger event associated to a serving cell / for a trigger event associated to a serving cell. The UE may use a parameter (value) in a trigger event associated to a neighboring cell / for a trigger event associated to a neighboring cell. The UE may use a parameter (value) in a trigger event indicated by the NW / for a trigger event indicated by the NW. The NW may configure an indication in the measurement configuration of which trigger event / for which trigger event the UE selects the parameter (value) in. The UE may be configured to trigger a measurement report (or initiate a measurement reporting procedure) based on a combined trigger condition of multiple trigger events (e.g., a first trigger event and a second trigger event).

[0311] The UE may not be configured to trigger (or initiate) a measurement report based solely on the first triggering event. The UE may not be configured to trigger (or initiate) a measurement report based solely on the second triggering event. If (or in response to) a triggering condition (e.g., entry condition) associated with the first triggering event is met but a triggering condition (e.g., entry condition) associated with the second triggering event is not met, then the UE may not trigger (or initiate) a measurement report. If (or in response to) a triggering condition (e.g., entry condition) associated with the second triggering event is met but a triggering condition (e.g., entry condition) associated with the first triggering event is not met, then the UE may not trigger (or initiate) a measurement report.

[0312] For example, the NW may configure a first trigger event based on cell quality and a second trigger event based on UE location as a combined trigger condition. The NW may configure a second parameter (e.g., reportOnLeave) in the first trigger event and the second trigger event. If the value of the second parameter in the first trigger event / used for the first trigger event is false, the UE may not trigger a measurement report when the leaving condition in the first trigger event and / or the second trigger event is met (or in response thereto). If the value of the second parameter in the first trigger event / used for the first trigger event is true, the UE may trigger a measurement report when the leaving condition in the first trigger event and the second trigger event is met (or in response thereto). If the value of the second parameter in the first trigger event / used for the first trigger event is true, the UE may trigger a measurement report when one of the leaving conditions in the first trigger event and the second trigger event is met (or in response thereto).

[0313] The UE may receive a configuration related to measurement and / or measurement reporting (or measurement reporting). The (measurement) configuration may include a combined trigger condition for measurement reporting. The combined trigger condition may be a plurality of trigger events (e.g., a first trigger event and a second trigger event) that need to be satisfied in order to trigger a measurement report (or initiate a measurement reporting procedure). The (measurement) configuration may include two or more trigger events for measurement reporting. The trigger event may include an entry condition and / or an exit condition. The entry condition and / or the exit condition may be and / or include one or more formulas. The UE may trigger a measurement report in response to satisfying the entry condition of the first trigger event and the second trigger event.

[0314] The (measurement) configuration may not include a non-combined trigger condition for measurement reporting. The (measurement) configuration may not include a single trigger condition for measurement reporting. The (measurement) configuration may not include a first trigger event without a second trigger event for measurement reporting. The (measurement) configuration may not include a second trigger event without a first trigger event for measurement reporting. The UE may not trigger measurement reporting in response to satisfying an entry condition for the first trigger event (e.g., and not satisfying an entry condition for the second trigger event). The UE may not trigger measurement reporting in response to satisfying an entry condition for the second trigger event (e.g., and not satisfying an entry condition for the first trigger event).

[0315] The (measurement) configuration may include a first parameter (e.g., timeToTrigger), a second parameter (e.g., reportOnLeave), and / or a third parameter (e.g., useWhiteCellList) in / for a trigger event. The third parameter may be configured when the trigger event (or at least one of them) is associated with a neighboring cell.

[0316] In various embodiments, the triggering event may be associated with a serving cell and / or a neighboring cell. The serving cell may be a special cell (SpCell) of the UE. The serving cell may be a secondary cell (SCell) of the UE. The neighboring cell may be one of multiple neighboring cells of the UE.

[0317] In various embodiments, the cell quality-based trigger event, the measurement-based trigger event and / or the existing trigger event may be at least one of the following (or a combination of the following events):

[0318] ● The radio conditions of the serving cell become better than the absolute threshold;

[0319] ● The radio conditions of the serving cell become worse than the absolute threshold;

[0320] ● The radio condition of the neighboring / candidate cell becomes better than the primary cell (PCell) / primary and secondary cells (PSCell);

[0321] ● The radio conditions of the neighboring / candidate cells become better than the absolute threshold;

[0322] The radio conditions of the PCell / PSCell and / or serving cell become worse than an absolute threshold, and the radio conditions of the neighboring / candidate cell and / or SCell become better than another absolute threshold;

[0323] • The radio condition of the neighboring / candidate cell becomes better than the SCell by an offset.

[0324] In various embodiments, the UE location-based triggering event and / or the location-based triggering event may be at least one of the following (or a combination of the following events):

[0325] The distance between the UE and the serving cell center becomes greater than the absolute threshold;

[0326] The distance between the UE and the serving cell center becomes smaller than the absolute threshold;

[0327] The distance between the UE and the center of the neighboring / candidate cell becomes greater than the absolute threshold;

[0328] The distance between the UE and the center of the neighboring / candidate cell becomes smaller than the absolute threshold;

[0329] The distance between the UE and the serving cell center becomes greater than the absolute threshold, and the distance between the UE and the neighboring / candidate cell center becomes less than the absolute threshold;

[0330] • The distance between the UE and the neighbor / candidate cell center becomes offset less than the distance between the UE and the serving cell center.

[0331] • The distance between the UE and the serving cell center becomes offset greater than the distance between the UE and the neighboring / candidate cell center.

[0332] In various embodiments, the center of a cell (e.g., a serving cell, a neighboring cell) may be replaced by other reference locations of the cell. The reference location of the cell may be the geographical location of the center of the cell on the ground. The reference location of the cell may be a virtual location defined by the network (e.g., the geographic area is divided into a rectangular grid and the reference location is represented by an index of the grid). The reference location of the cell may be provided to the UE by the network. The reference location of the cell may be derived by the UE (based on, for example, satellite locations and a mapping of satellite locations to cell locations).

[0333] In various embodiments, one, some, and / or all instances of "radio conditions" may correspond to "cell quality", may be supplemented by "cell quality", and / or may be replaced by "cell quality". The radio conditions and / or measurement results may be represented by RSRP, RSRQ, and / or SINR. The radio conditions and / or measurement results may be relative to a path loss reference, an average of a set of path loss references, and / or a reference signal of a beam (e.g., SSB, CSI-RS).

[0334] In various embodiments, one, some and / or all instances of “satisfying a trigger event” may correspond to “satisfying the trigger event”, “satisfying the criteria of a trigger event” and / or “satisfying the (trigger) condition of a trigger event”, may be supplemented by “satisfying the trigger event”, “satisfying the criteria of a trigger event” and / or “satisfying the (trigger) condition of a trigger event”, and / or may be replaced by “satisfying the trigger event”, “satisfying the criteria of a trigger event” and / or “satisfying the (trigger) condition of a trigger event”.

[0335] Similar problems described above may also occur when measurement configuration and / or triggering events are used to trigger or initiate conditional handover (or conditional reconfiguration). The method described above may also be applied to conditional handover (or conditional reconfiguration).

[0336] In various embodiments, the measurement report may be replaced by a conditional handover (or conditional reconfiguration). For example, the triggering condition for triggering the measurement report may be replaced by a triggering condition for triggering the conditional handover (or conditional reconfiguration).

[0337] The UE may be in a cell of the NTN. The UE may be connected to a cell of the NTN. The UE may be connected to LEO, GEO, MEO, HEO and / or HAPS.

[0338] UE may refer to a UE or an RRC entity of a UE.

[0339] The UE may be a NR device. The UE may be a NR light device. The UE may be a device with insufficient capabilities. The UE may be a mobile phone. The UE may be a wearable device. The UE may be a sensor. The UE may be a fixed device.

[0340] The network may be a network node. The network may be a base station. The network may be an access point. The network may be an eNB. The network may be a gNB. The network may be a gateway.

[0341] See also Fig.13 , through this and other concepts, systems and methods of the present invention, NW's method 1000 includes: configuring multiple trigger events (step 1002), including at least a first trigger event and a second trigger event as a combined trigger condition in a measurement configuration (step 1004), and configuring a first parameter, a second parameter and / or a third parameter associated with the combined trigger condition in the measurement configuration (step 1006).

[0342] In various embodiments, the first triggering event may be a triggering event based on cell quality.

[0343] In various embodiments, the second triggering event may be a triggering event based on the UE location.

[0344] In various embodiments, the first triggering event and the second triggering event may be associated with a serving cell and / or a neighboring cell.

[0345] In various embodiments, the first parameter specifies the length of the duration of a triggering event (eg, a first triggering event, a second triggering event) that needs to be satisfied in order to trigger the measurement report.

[0346] In various embodiments, the second parameter indicates whether the measurement report is triggered when (or in response to) a departure condition in a triggering event (eg, a first triggering event, a second triggering event) is met.
