[0002] In New Radio (NR) non-terrestrial networks (NTN), the network (NW) needs to carry satellite ephemeris information in system messages for cell reference position calculation.

[0070] To better understand the technical solution of this application, the following will be introduced first:

[0071] NTN Introduction

[0072] A typical NTN deployment scenario is as follows. Figure 1b As shown, the link between the UE and the satellite is called the service link, and the link between the satellite and the ground gateway is called the feeder link. In some scenarios (such as LEO satellites), service link and / or feeder link handovers occur due to satellite movement. For service link handovers, the serving satellite for all UEs within the cell needs to switch from one satellite to another. For feeder link handovers, a specific satellite needs to switch from one ground gateway to another.

[0073] Furthermore, the serving cells of Low Earth Orbit (LEO) satellites can be further classified into Earth Fixed Cells (EFC) and Earth Moving Cells (EMC). EFC means that the satellite's serving cell remains stationary in a certain area of ​​the Earth's surface for a period of time; this is typically achieved by the satellite rotating its beam. For EMC, the satellite's serving cell moves across the Earth's surface, and the UE can calculate the serving cell's reference position on the Earth's surface at a given time based on the satellite's ephemeris information.

[0074] Location-based mobility management

[0075] like Figure 1cAs shown, NTN cells suffer from a lack of sharp drop in Reference Signal Received Power (RSRP) at cell edges, making traditional TN cell-based mobility management methods, which rely on signal quality strength, unsuitable for NTN cells. Therefore, R17 / R18 NR introduced a location-based Radio Resource Management (RRM) triggering mechanism, along with location-based triggering for measurement reporting and conditional handover. For example, in the location-based RRM triggering mechanism, when the UE determines that the distance between its location and the reference location of the serving cell is less than a threshold, the UE may not perform neighbor cell RRM measurements (e.g., intra-frequency measurement, inter-frequency measurement, inter-system measurement). Conversely, when the UE determines that the distance between its location and the reference location of the serving cell is greater than a threshold, and the distance between its location and the reference location of the target neighbor cell is less than a threshold, it performs measurement reporting or conditional handover. If the serving cell is EMC, the UE needs to calculate the reference position based on satellite ephemeris information when calculating the reference position of the serving cell and the target neighboring cell.

[0076] In NR NTN, the NW needs to carry satellite ephemeris information in system messages for cell reference position calculation. Ephemeris information mainly includes satellite orbit information, indicating the satellite's on-orbit movement, including orbital altitude, inclination, perigee angle, and argument of perigee. This signaling overhead is approximately 270 bits. Furthermore, the network updates the ephemeris information over a period of time (validity duration), during which the UE also re-acquires the ephemeris information. After obtaining the ephemeris information, the UE cannot directly obtain the satellite's ground coverage or the movement of its coverage area; it needs to perform complex calculations based on the ephemeris information. Broadcasting ephemeris information results in significant system overhead and reduces system spectrum efficiency. Additionally, the UE's periodic acquisition of ephemeris information negatively impacts UE power consumption, and the algorithm implementation is quite complex.

[0077] The information processing method provided in this application will be described in detail below with reference to the accompanying drawings, through some embodiments and application scenarios.

[0078] See Figure 2 This application provides an information processing method, in which a terminal is the executing entity, and the method includes:

[0079] Step 201: The terminal receives target configuration information from the network-side device;

[0080] Step 202: The terminal determines its geographical location;

[0081] Step 203: The terminal executes the target operation based on the terminal's geographical location and target configuration information;

[0082] The target configuration information is used to determine the geographical location of the cell, and the target configuration information is associated with at least one of the following:

[0083] The reference geographic location of the cell, the velocity vector of the reference geographic location of the cell, and the propagation delay difference (PDD) between cells;

[0084] The target operation includes at least one of the following:

[0085] Measurement, measurement reporting, switching.

[0086] The aforementioned network-side equipment can be a ground-based communication base station, which can receive network-side information from a ground gateway through satellite signal reflection; the aforementioned network-side equipment can also be a satellite, that is, a satellite with certain base station communication functions, which has the ability to provide communication information to the terminal. This application does not limit the specific type of network-side equipment.

[0087] The aforementioned target configuration information differs from ephemeris information. It is associated with at least one of the cell's reference geographic location, the velocity vector of the cell's reference geographic location, and the inter-cell PDD, and is used by the terminal to calculate the cell's geographic location. Its signaling overhead is less than that of ephemeris information.

[0088] Specifically, PDD can be the difference between the delay from the serving cell base station sending a downlink synchronization reference signal, such as a synchronization signal block (SSB), to the UE and the delay from the neighboring cell base station sending a downlink synchronization reference signal to the UE. For example, it could be the difference between the delay from the first time-domain symbol position of the downlink synchronization reference signal sent by the serving cell base station to the UE receiving that downlink synchronization reference signal and the delay from the first time-domain symbol position of the downlink synchronization reference signal sent by a neighboring cell base station to the UE receiving that downlink synchronization reference signal. Another example is the difference between the delay from the serving cell base station sending the downlink synchronization reference signal at the cell's corresponding timing reference point to the UE receiving that downlink synchronization reference signal and the delay from the first time-domain symbol position of the downlink synchronization reference signal sent by a neighboring cell base station at the cell's corresponding timing reference point to the UE receiving that downlink synchronization reference signal.

[0089] Additionally, before sending the PDD, the base station can also trigger the UE to report its geographical location. For example, before configuring the measurement configuration containing the PDD for the UE, the network first configures the corresponding positioning signal configuration for the UE, triggering the UE to perform positioning signal measurement and report the calculated geographical location. The base station then obtains the geographical location reported by the UE and configures the PDD value.

[0090] The measurement in the above target operation can be RRM measurement, and the handover in the above target operation can refer to cell handover, such as handover from the serving cell to a neighboring cell, which can also be called conditional handover.

[0091] In the embodiments of this application, the terminal can perform at least one of the target configuration information associated with at least one of the following: the reference geographical location of the cell, the velocity vector of the reference geographical location of the cell, and the PDD between cells, sent by the network-side device. This eliminates the overhead of satellite broadcasting ephemeris information and avoids the complexity of the terminal calculating the cell reference satellite based on the ephemeris information. This has positive significance for improving the spectrum efficiency of satellite communication and reducing terminal power consumption and complexity.

[0092] In one optional implementation, the target configuration information includes at least one of cell geographic location information and epoch time associated with the cell geographic location information;

[0093] The geographical location information of the residential community includes at least one of the following:

[0094] (1) Information on the reference geographical location of the service area;

[0095] For example, this information may be longitude, latitude, altitude, and / or coverage radius; additionally, a serving cell may have reference geographic location information for multiple beams, and optionally, associated PDD information; or, a serving cell may carry multiple reference geographic locations, each of which is associated with Epoch time information.

[0096] (2) Velocity vector information of the reference geographical location of the serving cell;

[0097] Optionally, the velocity vector may include velocity information for the three-dimensional coordinate axes of latitude, longitude, and altitude (e.g., first-order rate of change of motion, second-order rate of change of motion). This is used to indicate the trend of the EMC's reference geographic location changing over time, allowing the UE to calculate the EMC's reference geographic location at different points in time.

[0098] (3) Information on the reference geographical location of neighboring communities;

[0099] The reference geographic location information of the neighboring cells can be associated with one or more frequency points, or one or more physical cell IDs (PCIs);

[0100] (4) Velocity vector information of the reference geographical location of neighboring cells;

[0101] Optionally, the velocity vector may include velocity information for the three-dimensional coordinate axes of latitude, longitude, and altitude (e.g., first-order rate of change of motion, second-order rate of change of motion). This is used to indicate the trend of the EMC's reference geographic location changing over time, allowing the UE to calculate the EMC's reference geographic location at different points in time.

[0102] (5) PDD of the service community and neighboring communities.

[0103] The information is used to adjust the downlink reference signal measurement timing configuration (e.g., SSB measurement timing configuration, SMTC) when measuring inter-frequency cells or inter-RAT frequency cells; additionally, the PDD rate of change over time (e.g., first-order rate of change) can be configured.

[0104] In one optional implementation, the terminal performs measurements based on the terminal's geographical location and target configuration information, including:

[0105] The terminal performs at least one of the first and second measurements according to preset conditions;

[0106] The preset conditions are associated with geographic location information. The first measurement includes intra-frequency measurement (e.g., intra-frequency measurement), and the second measurement includes inter-frequency measurement (e.g., inter-frequency cell measurement) or inter-system measurement (e.g., inter-RAT frequency cell measurement).

[0107] Additionally, the terminal supports location-based measurement initiation capabilities, and it is in a disconnected state (e.g., RRC IDLE / INACIVE), specifically:

[0108] In one optional implementation, the terminal performs a first measurement based on preset conditions, including:

[0109] If the first condition is met, the terminal skips the first measurement;

[0110] If the first condition is not met, the terminal performs the first measurement;

[0111] The first condition includes at least one of the following:

[0112] (1) The distance between the terminal’s geographical location and the reference geographical location of the serving cell is less than or equal to the first threshold value (this threshold value may be a network configuration or protocol agreement; other threshold values ​​in the following text are similar to the first threshold value and will not be repeated).

[0113] (2) The serving cell meets the S criterion. The S criterion refers to the cell selection criterion, which can be that the RSRP value of the selected cell is >0 and the Reference Signal Received Quality (RSRQ) value of the selected cell is >0.

[0114] In one optional implementation, the terminal performs a second measurement based on preset conditions, including:

[0115] If the second condition is met, the terminal skips the second measurement; optionally, the priority of the inter-frequency / inter-RAT frequency involved in the second measurement is lower than the priority of the current serving cell frequency.

[0116] If the third condition is met, the terminal performs the second measurement;

[0117] The second condition includes at least one of the following:

[0118] (1) The distance between the terminal's geographical location and the reference geographical location of the serving cell is less than or equal to the first threshold value;

[0119] (2) The distance between the terminal's geographical location and the reference geographical location of the neighboring cell is greater than or equal to the second threshold value;

[0120] (3) The serving cell satisfies the S criterion;

[0121] The third condition includes at least one of the following:

[0122] (1) The distance between the terminal's geographical location and the reference geographical location of the serving cell is greater than the first threshold value;

[0123] (2) The distance between the terminal's geographical location and the reference geographical location of the neighboring cell is less than the second threshold value;

[0124] (3) The service cell does not meet the S criterion.

[0125] In one optional implementation, the terminal performs measurement reporting based on the terminal's geographical location and target configuration information, including:

[0126] If the fourth condition is met, the terminal carries the target measurement identifier in the measurement result and sends the measurement result to the network-side device.

[0127] If the fifth condition is met, the terminal removes the target measurement identifier from the measurement result and sends the measurement result to the network-side device.

[0128] Among them, the target measurement identifier is associated with the target event, and the target event is used to trigger the reporting of measurement results;

[0129] In this embodiment, when a measurement result is reported, the terminal determines whether to include a target measurement identifier associated with the target event in the reported measurement result, based on the terminal's geographical location and target configuration information. If the network side obtains the target measurement identifier in the reported measurement report, it indicates that the terminal is currently, or was, after the previous measurement report and before the current measurement report (or before the first measurement report), satisfying the fourth condition. Additionally, the terminal supports geographical location-based measurement capabilities and is in a connected state (e.g., RRC CONNECTED), specifically:

[0130] The fourth condition includes at least one of the following:

[0131] (1) The difference between the distance between the terminal’s geographical location and the reference geographical location of the serving cell and the first assumed bias value is greater than or equal to the third threshold value;

[0132] The aforementioned assumed bias value refers to setting it to a positive value to avoid inaccurate judgment of whether the UE's location meets the conditions due to fluctuations in the distance between the terminal's location and the cell's reference geographical location around the threshold value (e.g., due to inaccurate GNSS positioning drift).

[0133] (2) The difference between the distance between the terminal's geographical location and the reference geographical location of the neighboring cell and the second assumed bias value is less than or equal to the fourth threshold value;

[0134] The fifth condition includes at least one of the following:

[0135] (1) The difference between the distance between the terminal's geographical location and the reference geographical location of the serving cell and the third assumption bias value is less than the third threshold value obtained;

[0136] (2) The difference between the distance between the terminal’s geographical location and the reference geographical location of the neighboring cell and the fourth assumption bias value is greater than or equal to the fourth threshold value.

[0137] Among them, the first, second, third, and fourth assumption bias values ​​can be configured to 0, not configured, or not exist (that is, the condition becomes that the difference between the distance between the terminal's geographical location and the reference geographical location of the serving cell is greater than or equal to the third threshold value).

[0138] In one optional implementation, the terminal performs a handover based on the terminal's geographical location and target configuration information, including:

[0139] If the sixth condition is met, the terminal switches from the serving cell to the target neighboring cell;

[0140] The aforementioned target neighbor cell refers to the terminal selecting one target neighbor cell when multiple candidate neighbor cells meet the sixth condition. For example, if multiple candidate neighbor cells meet the condition, the UE can determine the target neighbor cell based on the frequency priority of the corresponding cell (e.g., prioritizing cells on higher priority frequencies) or based on the measurement results (e.g., prioritizing cells with better results).

[0141] The sixth condition includes at least one of the following:

[0142] (1) The difference between the distance between the terminal’s geographical location and the reference geographical location of the serving cell and the fifth assumption bias value is greater than or equal to the fifth threshold value;

[0143] (2) The difference between the distance between the terminal’s geographical location and the reference geographical location of the neighboring cell and the sixth assumption bias value is less than or equal to the sixth threshold value;

[0144] (3) The measurement results of the serving cell are all less than or equal to the seventh threshold within the preset time;

[0145] (4) The measurement duration value of the serving cell is greater than or equal to the eighth threshold, but less than or equal to the sum of the eighth threshold and the preset duration offset value;

[0146] (5) The measurement results of neighboring cells are all greater than the ninth threshold within the preset time.

[0147] The fifth and sixth assumption bias values ​​can be configured to 0, not configured, or not exist.

[0148] Additionally, the terminal supports location-based conditional handover capabilities and is in a connected state (RRCCONNECTED).

[0149] In one optional implementation, when the serving cell is an EMC, the reference geographical location of the serving cell / neighboring cells can be obtained as follows:

[0150] (1) When the base station is configured with multiple reference geographical locations and their associated Epoch Times for the serving / neighboring cells, the UE can determine the reference geographical location based on the currently obtained world time (which can be obtained from the Global Navigation Satellite System (GNSS) or from the System Information Block (SIB) message). For example, if Epoch Time#1 corresponds to reference geographical location #1, Epoch Time#2 corresponds to reference geographical location #2, and Epoch Time#3 corresponds to reference geographical location #3, and the UE obtains the current time between Epoch Time#1 and Epoch Time#2, then the reference geographical location of the cell is considered to be reference geographical location #1.

[0151] (2) When the base station is configured with a reference geographic location and its associated Epoch Time for the serving / neighboring cell, as well as the velocity vector information of the cell's reference geographic location, the UE can deduce the reference geographic location corresponding to the current time. For example, based on the indicated reference geographic location and rate of change, a new reference geographic location is calculated: (new longitude, new latitude) = (reference geographic location longitude + (t-Epoch time) * first-order longitude velocity rate of change, reference geographic location latitude + (t-Epoch time) * first-order latitude velocity rate of change).

[0152] In one alternative implementation, the method further includes:

[0153] The terminal adjusts the timing configuration of downlink reference signal measurement according to the target configuration information, and performs downlink reference signal measurement of neighboring cells according to the adjusted timing configuration;

[0154] The terminal adjusts the timing configuration of the downlink reference signal measurement according to the target configuration information, including at least one of the following:

[0155] (1) When the PDD of the serving cell and neighboring cells is configured on the network side equipment, the terminal adjusts the timing configuration of the downlink reference signal measurement according to the downlink time DLtiming and the PDD indicated in the target configuration information.

[0156] The base station configures the propagation delay difference (PDD) between the serving cell and one or more neighboring cells. When the UE performs measurements, it adjusts the downlink reference signal measurement timing configuration according to the current DL timing and the indicated PDD value, and then performs the measurement of the downlink reference signal of the neighboring cell according to the adjusted timing configuration.

[0157] (2) When the network-side equipment configures a PDD list of serving cell and neighboring cells, and the difference between the distance between the reference geographical location of the serving cell corresponding to the target PDD and the geographical location of the terminal is less than the seventh value, the terminal uses the target PDD to adjust the timing configuration of downlink reference signal measurement.

[0158] (3) Configure a PDD list of serving cell and neighboring cells on the network side device, and if the difference between the distance between the reference geographical location of the serving cell corresponding to the target PDD and the geographical location of the terminal is less than the seventh value, the terminal assumes that the PDD is 0, or adjusts the timing configuration of downlink reference signal measurement according to the PDD corresponding to the first PDD in the PDD list.

[0159] The base station is configured with a list of propagation delay differences between the serving cell and one or more neighboring cells. Each element in the list includes the PDD reference geographic location (specifically, the reference geographic location of the serving cell; for example, a serving cell may have multiple PDD reference geographic location areas, where the first PDD reference geographic location area corresponds to the first PDD, the second PDD reference geographic location area corresponds to the second PDD, and so on), radius information, and the PDD values ​​of one or more neighboring cells (e.g., ...). Figure 3 Once the UE obtains its own geographic location, if there exists an element where the difference between the distance between the reference geographic location of the corresponding PDD and the UE's own geographic location and the seventh assumption offset value is less than a threshold value, then the UE uses the corresponding PDD to adjust the downlink reference signal measurement timing configuration and performs the corresponding neighbor cell measurement. If no element is adapted, the UE assumes the PDD is 0, or uses the PDD corresponding to the first element to adjust the downlink reference signal measurement timing configuration.

[0160] The seventh bias value may not be configured or may not exist.

[0161] (4) When the network-side equipment is configured with the correspondence between PDD and Epoch Time, the terminal adjusts the timing configuration of downlink reference signal measurement according to the PDD corresponding to the first time, and performs downlink reference signal measurement of neighboring cells according to the adjusted timing configuration.

[0162] The base station can also configure the Epoch Time corresponding to the PDD, thus configuring different Epoch Times to correspond to different PDDs. For example, Epoch Time#1 corresponds to PDD#1, Epoch Time#2 corresponds to PDD#2, and Epoch Time#3 corresponds to PDD#3. If the UE obtains the current time between Epoch Time#1 and Epoch Time#2, the UE uses PDD#1 to adjust the downlink reference signal measurement timing configuration. If it is between Epoch Time#2 and Epoch Time#3, the UE uses PDD#2 to adjust the downlink reference signal measurement timing configuration.

[0163] (5) When the network-side equipment is configured with the corresponding relationship between PDD, Epoch Time and PDD change rate, the terminal calculates the target PDD based on the PDD and PDD change rate corresponding to the first time, and adjusts the timing configuration of downlink reference signal measurement based on the target PDD.

[0164] The base station can also configure the Epoch Time corresponding to the PDD and the PDD change rate over time. That is, the PDD can also correspond to one or more Epoch Times and one or more PDD change rates over time. For example, Epoch Time#1 corresponds to PDD#1 and change rate#1, Epoch Time#2 corresponds to change rate#2, and Epoch Time#3 corresponds to change rate#3. The UE calculates the final PDD value based on PDD#1 and the current time. For example, at Epoch Time#4, the PDD is calculated as PDD* = PDD#1 + change rate#1*(T2-T1) + change rate#2*(T3-T2) + change rate#3*(T4-T3). The UE uses PDD* to adjust the downlink reference signal measurement timing configuration.

[0165] See Figure 4 This application provides an information processing method, in which a network-side device executes the method, which includes:

[0166] Step 401: The network-side device sends the target configuration information to the terminal;

[0167] The target configuration information is used to determine the geographical location of the cell, and the target configuration information is associated with at least one of the following:

[0168] The reference geographical location of the cell, the velocity vector of the reference geographical location of the cell, and the PDD between cells.

Therefore, the understanding of the various technical features in the network-side method can refer to the relevant content on the terminal side, and the embodiments of this application will not repeat them here.

[0179] or,

[0180] The network-side device receives the measurement results from the terminal, but the measurement results do not carry the target measurement identifier.

[0181] Among them, the target measurement identifier is associated with the target event, and the target event is used to trigger the reporting of measurement results.

[0182] In one alternative implementation, the method further includes at least one of the following:

[0183] Network-side equipment configures the serving cell and neighboring cells' PDDs for the terminal;

[0184] Network-side devices configure the serving cell and neighboring cell PDD lists for the terminal;

[0185] The network-side equipment configures the mapping between PDD and Epoch Time for the terminal;

[0186] Network-side devices configure the correspondence between PDD, Epoch Time, and PDD change rate for terminals.

[0187] The technical solution of this application is described below with reference to specific embodiments:

[0188] Example 1: Location-based measurement for cell-reselection (EMC type)

[0189] The main idea of ​​this embodiment is to solve the signaling overhead problem of the base station needing to send ephemeris signals and the complexity problem of the UE needing to infer the reference geographical location of the serving cell and calculate the difference in propagation delay between the serving cell and the neighboring cell by broadcasting the reference geographical location information of the serving cell and the difference in propagation delay between the serving cell and the neighboring cell based on the satellite ephemeris information. This improves the spectrum efficiency of the NTN system and reduces the implementation complexity of the UE.

[0190] The corresponding signaling process is as follows: Figure 5a As shown, the corresponding steps are as follows: Figure 5b As shown;

[0191] In detail:

[0192] Step 1: The base station broadcasts its geographic location information via a broadcast message. This geographic location information includes the reference geographic location of the current serving cell and its PDD value with neighboring cells. After broadcasting this message, the base station does not need to broadcast the ephemeris information of the serving cell and neighboring cells, saving system message overhead and thus improving spectrum efficiency.

[0193] The broadcast geographic location information carried in the SIB specifically includes:

[0194] a) Reference geographical location information of the service cell, including longitude, latitude, rate of change of longitude, rate of change of latitude, and epoch time;

[0195] b) Reference geographical location information of PCI#2 neighboring cells, including longitude, latitude, longitude migration rate, latitude migration rate, and epoch time;

[0196] c) Intra-frequency measurement configuration, including a first SMTC configuration and a second SMTC configuration (used to determine the measurement period of SSB); optionally, the first configuration is associated with the PCI of the serving cell (e.g., the UE only needs to measure the downlink reference signal SSB corresponding to the PCI of the serving cell during the first SMTC window), and the second SMTC configuration is associated with the PCI#2 of the neighboring cell (e.g., the UE only needs to measure the downlink reference signal SSB corresponding to the PCI#2 of the neighboring cell during the first SMTC window). Additionally, the second SMTC configuration includes the PDD#2 value.

[0197] d) Intre-frequency measurement configuration, which includes a frequency point value (i.e., the first frequency point) and a third SMTC configuration. The third SMTC configuration also includes the PDD#3 value and the first-order rate of change of PDD over time #3, and the second-order rate of change of PDD #3; additionally, the reference geographic location information associated with the frequency point.

[0198] e) Distance threshold value corresponding to the service cell;

[0199] f) Distance threshold value corresponding to PCI#2 neighboring cell;

[0200] g) The distance threshold associated with the first frequency point;

[0201] Step 2: The UE obtains the broadcast message and the configuration it carries; since the broadcast message already indicates the reference geographical location of the EMC and the PDD of neighboring cells, the UE does not need to use ephemeris to calculate the reference location of the EMC and the PDD of neighboring cells, which reduces the implementation complexity. Moreover, it does not need to obtain ephemeris from the SIB, which is also beneficial for UE energy saving.

[0202] (1) The UE obtains its own geographical location if the following conditions are met simultaneously.

[0203] i. The distance between the UE's own geographic location and the reference geographic location of the serving cell is less than the distance threshold value corresponding to the serving cell;

[0204] ii. The measurement results of the current serving cell satisfy the S criterion;

[0205] The UE then skips intra-frequency and inter-frequency cell measurements.

[0206] The method for the UE to calculate the reference geographical location of the serving cell at the current time includes: calculating a new reference geographical location based on the indicated reference geographical location, the rate of change of longitude, the rate of change of latitude, and epoch time. Specifically, (new longitude, new latitude) = (indicated reference geographical location longitude + (t-epoch time) * first-order rate of change of longitude, reference geographical location latitude + (t-epoch time) * first-order rate of change of latitude).

[0207] (2) If the distance between the UE's own geographic location and the reference geographic location of the serving cell is greater than the distance threshold value corresponding to the serving cell, intra-frequency and inter-frequency cell measurements are initiated. Specifically, the SSB corresponding to the serving cell is measured according to the first SMTC configuration. Additionally, if the distance between the UE's own geographic location and the reference geographic location of a neighboring cell is greater than the distance threshold value corresponding to the neighboring cell, the UE skips the measurement of that neighboring cell. For example, if the distance between the UE's own geographic location and the reference geographic location of the neighboring cell of PCI#2 is greater than the distance threshold value corresponding to the neighboring cell of PCI#2, the UE will not apply the second SMTC to measure the downlink reference signal SSB corresponding to the neighboring cell PCI#2 (i.e., skip the measurement of the downlink reference signal SSB corresponding to the neighboring cell PCI#2). As another example, if the distance between the UE's own geographic location and the reference geographic location associated with the first inter-frequency point is less than the corresponding distance threshold value, the UE applies the third SMTC according to PDD#3 to measure the downlink reference signal SSB on the first frequency point (i.e., the time offset of the third SMTC is set to PDD#3).

[0208] Specifically, when the UE performs inter-frequency measurements (generally once per DRX cycle according to the SMTC window length), it updates the value of PDD#3. Specifically, PDD#3* = PDD#3 + (t-epoch time) * first-order PDD rate of change with time (longitude shift rate of change) + (t-epoch time)^2 * second-order PDD rate of change with time). For example, if the UE performs inter-frequency measurements at time T1 in the first DRX cycle, then PDD#3* = PDD#3 + (T1-epoch time) * first-order PDD rate of change with time (longitude shift rate of change) + (T1-epoch time)^2 * second-order PDD rate of change with time. Similarly, if the UE performs inter-frequency measurements at time T2 in the second DRX cycle, then PDD#3* = PDD#3 + (T2-epoch time) * first-order PDD rate of change with time (longitude shift rate of change) + (T2-epoch time)^2 * second-order PDD rate of change with time. T1 and T2 can be obtained from GNSS positioning.

[0209] Example 2: Location-based conditonal home location (HO) for EMC

[0210] The main idea of ​​this embodiment is to solve the signaling overhead problem of the base station needing to send ephemeris information and the complexity of the UE needing to calculate the reference geographical location of the serving cell and the reference geographical location of the candidate neighboring cells based on satellite ephemeris information by indicating the reference geographical location information of the serving cell and the candidate neighboring cells by the base station. This improves the spectrum efficiency of the NTN system and reduces the implementation complexity of the UE.

[0211] The corresponding signaling process is as follows: Figure 5c As shown, the corresponding steps are as follows: Figure 5d As shown:

[0212] In detail:

[0213] Step 1: The base station carries the conditional handover configuration and the geographical location information of the serving cell and candidate cells through the RRC reconfiguration message. In this way, the base station does not need to send the ephemeris information of the serving cell and neighboring cells to the UE, saving system message overhead and thus improving spectrum efficiency.

[0214] The conditional switching configuration carried in the RRC reconfiguration message specifically includes:

[0215] a) Reference geographical location information of the service cell, including longitude, latitude, rate of change of longitude, rate of change of latitude, and epoch time;

[0216] b) Reference geographical location information of PCI#2 candidate cells, including longitude, latitude, longitude migration rate, latitude migration rate, and epoch time;

[0217] c) First SMTC Configuration. The first SMTC configuration also includes the PDD#1 value and its corresponding Epoch time T1, the Epoch time T2 corresponding to the PDD#2 value, and the Epoch time T3 corresponding to the PDD#3 value; the first SMTC is used to measure PCI#2 candidate cells.

[0218] d) The distance threshold value corresponding to the service cell;

[0219] e) Distance threshold value corresponding to PCI#2 neighboring cell;

[0220] Step 2:

[0221] The UE obtains the RRC reconfiguration message, which carries the conditional handover configuration. Since the RRC reconfiguration message already indicates the reference geographical location of the EMC and the reference geographical location of the candidate cells, the UE does not need to use ephemeris to calculate the reference location of the EMC, thus reducing the implementation complexity.

[0222] (1) The UE obtains its own geographical location if the following conditions are met simultaneously.

[0223] i. The difference between the distance of the UE to its own geographic location and the reference geographic location of the serving cell and the first configuration assumption offset value (optional) is greater than the distance threshold value corresponding to the serving cell;

[0224] ii. The difference between the distance between the UE's own geographic location and the reference geographic location of the PCI#2 candidate cell and the second configuration assumption bias value (optional) is less than the sixth threshold value;

[0225] iii. The measurement results of the PCI#2 candidate cells are all greater than the threshold value within the specified time;

[0226] The UE then selects PCI#2 candidate cell as the target cell, and sends a reconfiguration completion message after synchronizing with the target cell.

[0227] The method by which the UE calculates the reference geographic location of the serving cell / candidate cell at the current time includes: calculating a new reference geographic location based on the indicated reference geographic location, the rate of change of longitude, the rate of change of latitude, and the Epoch time. Specifically, (new longitude, new latitude) = (indicated reference geographic location longitude + (t - epoch time) * first-order rate of change of longitude, reference geographic location latitude + (t - epoch time) * first-order rate of change of latitude). The UE will apply the first SMTC to measure the downlink reference signal SSB corresponding to candidate cell PCI#2. Specifically, if the current time T1 obtained by the UE is between Epoch Time#T1 and Epoch Time#T2, the UE uses PDD#1 to adjust the time offset of the first SMTC (i.e., adjusts the time offset of the first SMTC to PDD#1). If it is between Epoch Time#T2 and Epoch Time#T3, the UE uses PDD#2 to adjust the time offset of the first SMTC, and so on.
