AI Technical Summary
In NTN scenarios, the terminal's network measurement and control cannot adapt to height variations, leading to unnecessary power consumption and communication impacts.
The terminal determines the conditions that its own altitude meets, and selects an appropriate network to perform measurement operations based on the mapping relationship between altitude conditions and network measurement operations, including starting or stopping measurement operations in NTN and TN networks.
This effectively avoids unnecessary power consumption and communication impacts, improving the accuracy and efficiency of network selection.

[0069] Figure 1A is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.
[0070] As shown in Figure 1A, the communication system 100 includes a terminal 101 and a network device 102. For example, the network device (e.g., a terrestrial network device) can communicate with the terminal via an air device, such as based on a transparent transmission mode and / or a regenerative mode, as can be seen in the embodiments described below.
[0071] For example, aerial equipment can include satellites, drones, and aerial platforms.

[0076] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.
[0077] In some embodiments, the core network device 103 may be a single device, including a first network element 1031, a second network element 1032, etc., or it may be multiple devices or a group of devices, each including all or part of the first network element 1031, the second network element 1032, etc. Network elements may be virtual or physical.

However, this is not the only possibility.
[0080] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure.

[0083] In some embodiments, in an NTN (Non-terrestrial Network), a terminal can communicate with terrestrial network equipment via an air device.
[0084] For example, aerial equipment may include at least one of the following: a satellite, or a UAS (Uncrewed Aerial System) platform. The following embodiments primarily use a satellite as an example to illustrate the technical solutions of this disclosure.
[0085] Figure 1B is a schematic diagram of an NTN scenario according to an embodiment of the present disclosure.
[0086] For example, as shown in Figure 1B, a terrestrial data network, which may include core network equipment, access network equipment, etc., can transmit signals to satellites through gateways, and then the satellites transmit the signals to terminals.
[0087] For example, the link between a satellite and a terminal can be called a service link; for example, the link between a satellite and a gateway can be called a feeder link.
[0088] In some embodiments, the way terminals communicate with network devices in an NTN can be divided into transparent transmission mode and regeneration mode based on how the satellite processes the signal.
[0089] In transparent transmission mode, ground-based network equipment (such as core network equipment and access network equipment) can transmit signals to (e.g., via a gateway) a satellite. The satellite then converts the signal to its frequency band and transmits it to the terminal. In this process, the satellite only performs frequency conversion and signal amplification; it does not demodulate the signal. The satellite acts similarly to a repeater.
[0090] In regeneration mode, ground-based network equipment (such as core network equipment and access network equipment) can send signals to (e.g., via a gateway) satellites. The satellites first demodulate and decode the signals, then re-encode and modulate them (this process can be called regeneration), and then send the regenerated signals to the terminals via satellite frequency bands.
[0091] Because the coverage area of the satellite corresponding to an NTN cell is much larger than that of the access network equipment (such as base stations) corresponding to a TN cell (Terrestrial Network), the NTN cell is much larger.
[0092] In some embodiments, NTN introduces the feature of indicating TN coverage areas through system information. Terminals camped in an NTN cell can enable TN measurements when they are within the TN coverage area indicated by NTN.
[0093] In some embodiments, terminals in an NTN can also perform measurements on NTN cells, such as measurements on neighboring cells of the current cell. However, due to the large size of NTN cells, RRM (Radio Resource Management) measurements in NTN are difficult to accurately reflect the near-far effect. Therefore, for NTN measurements, time-based neighbor cell measurements and location-based neighbor cell measurements have been introduced.
[0094] Time-based neighbor cell measurement refers to the process where a terminal initiates measurement of neighboring NTN cells when the time for the serving NTN cell to cease service is about to arrive.
[0095] Location-based neighbor cell measurement refers to the process where a terminal initiates measurement of neighbor cells in the NTN when the distance from its location to the reference point (e.g., the center) of the serving NTN cell is greater than a distance threshold.
[0096] In some embodiments, the measurement of NTN cells, and the measurement of TN cells, serve one function of cell reselection.
[0097] The cell reselection process refers to the process by which a terminal initiates a cell reselection mechanism when it detects that the signal quality of the current serving cell has dropped below a certain threshold. This mechanism attempts to find a cell with a better signal and is more suitable for communication, and then switches to that cell for communication.
[0098] The cell reselection process may include at least one of the following steps:
[0099] Measuring neighboring cell signals: When the signal quality of the serving cell deteriorates, the terminal needs to measure the signal quality of surrounding neighboring cells. For example, it can measure indicators such as Reference Signal Receiving Power (RSRP) and Reference Signal Receiving Quality (RSRQ).
[0100] Ranking and Evaluation: The terminal can rank neighboring cells based on measurement results and evaluate whether cell reselection is necessary. The ranking criteria may include, for example, signal strength, network configuration parameters (such as cell reselection priority).
[0101] Triggering cell reselection: When certain conditions are met (such as R criterion, S criterion, etc.), such as when the signal of the current serving cell is below a certain threshold, or when there is a neighboring cell with a significantly better signal, the device will trigger the cell reselection process.
[0102] Perform reselection: After determining the target cell, the terminal performs steps such as synchronizing with the target cell and reading system information, and then switches to the target cell.
[0103] Although the NTN in the previous embodiments introduced TN measurement, the related measurement and control assumed that the terminal was on the ground. For example, the reference point indicated by the system information was located on the ground, and the coverage area of the TN cell indicated by the NTN was also determined based on the coordinates and radius of the reference point on the ground. While this is applicable to ground terminals, it presents some technical problems for scenarios where the terminal's altitude changes.
[0104] For example, when the terminal is on an airplane or a drone, even if the distance between the terminal and the TN cell reference point is less than the distance threshold, the terminal has not yet entered the altitude coverage range of the TN cell. In this case, if the terminal triggers a measurement of the TN cell, it will cause unnecessary power consumption.
[0105] For example, a terminal determines whether to start measuring neighboring cells based on the signal quality of the cell. During the process of ascending altitude (e.g., during takeoff), the signal quality of the TN cell may suddenly deteriorate after the terminal reaches a certain altitude, for example, when the terminal leaves the altitude coverage range of the TN cell. In this case, if the terminal only determines whether to start measuring neighboring cells based on signal quality, the measurement will be started too late and may cause the terminal to disconnect from the network, thereby affecting the terminal's service initiation and transmission.
[0106] Figure 2 is an interactive schematic diagram illustrating a measurement determination method according to an embodiment of the present disclosure.
[0107] In some embodiments, the measurement determination method can be performed by a terminal. For example, the terminal can measure either the NTN or the TN.
[0108] It should be noted that some or all of the steps in the embodiments of this disclosure may be executed in a non-connected state (e.g., idle state, inactive state) or in a connected state, and this disclosure does not limit this.
[0109] As shown in Figure 2 (where the dashed lines represent optional steps), the measurement determination method may include the following steps:
[0110] In some embodiments, the terminal determines the altitude condition satisfied by its current first altitude.
[0111] In step S201, the terminal determines the mapping relationship between the altitude conditions and the terminal's measurement operation on the first network.
[0112] For example, the mapping relationship between the terminal's measurement operations on the first network can be determined based on predefined rules (such as protocol agreements).
[0113] For example, a network device can send indication information to a terminal, which indicates the mapping relationship between altitude conditions and the terminal's measurement operations on the first network. For example, the indication information can be carried in at least one of the following: SIB (System Information Block), RRC (Radio Resource Control) message, DCI (Downlink Control Information), or MAC CE (Media Access Control Element).
[0114] In some embodiments, the first network includes at least one of the following: a terrestrial network (TN) and a non-terrestrial network (NTN).
[0115] In step S202, the terminal determines the measurement operation for the first network based on the altitude conditions and mapping relationship.
[0116] For example, the altitude condition satisfied by the first altitude at which the terminal is located is denoted as the first altitude condition. The terminal can determine the first network and measurement operation corresponding to the first altitude condition in the mapping relationship, and then perform the corresponding measurement operation for the determined first network.
[0117] For example, the terminal can send the measurement results obtained from the measurement to the network device.
[0118] For example, the terminal can perform cell selection and / or cell reselection based on the measurement results.
[0119] For example, the measurement results may include at least one of the following: RSRQ, RSRP, SINR (Signal to Interference plus Noise Ratio).
[0120] In some embodiments, the measurement operations performed on the first network may include measurement operations on objects in the first network.
[0121] For example, the object includes at least one of the following: frequency point, cell.
[0122] For example, a frequency point can include any frequency point that needs to be measured during cell selection and cell reselection. For example, a frequency point can include a frequency band identifier, such as an identifier defined by a protocol like ARFCN (Absolute Radio Frequency Channel Number).
[0123] For example, a residential community can include the serving community and neighboring communities.
[0124] According to embodiments of this disclosure, when determining the measurement operations to be performed on NTN and TN, the terminal may not be limited to considering the distance to the reference point, but may also consider the first altitude at which the terminal is located. Then, based on the altitude conditions satisfied by the first altitude and the mapping relationship between the altitude conditions and the measurement operations on the first network, the measurement operation and the first network targeted by the measurement operation can be determined. This is beneficial for the terminal to select an appropriate network to perform the measurement operation, so as to avoid problems such as wasted power consumption and impact on communication.
[0125] In some embodiments, the height condition may be determined based on at least one of the following:
[0126] Altitude range;
[0127] Height threshold;
[0128] Increasing in height;
[0129] The height decreases gradually.
[0130] In some embodiments, height increase can be monotonically increasing (e.g., monotonically increasing within a time period, where for two adjacent moments within the time period, the terminal height corresponding to the later moment is higher than or equal to the terminal height corresponding to the earlier moment), or non-monotonically increasing (e.g., non-monotonically increasing within a time period, where the terminal height corresponding to the end of the time period is higher than the terminal height corresponding to the beginning of the time period); height decrease can be monotonically decreasing (e.g., monotonically decreasing within a time period, where for two adjacent moments within the time period, the terminal height corresponding to the later moment is lower than or equal to the terminal height corresponding to the earlier moment), or non-monotonically decreasing (e.g., non-monotonically decreasing within a time period, where the terminal height corresponding to the end of the time period is lower than the terminal height corresponding to the beginning of the time period).
[0131] In some embodiments, the height condition includes at least one of the following:
[0132] The first altitude is higher than the altitude threshold;
[0133] The first height is below the height threshold;
[0134] The first altitude satisfies the requirement of increasing altitude;
[0135] The first altitude satisfies the condition of decreasing altitude.
[0136] The first altitude is within the altitude range;
[0137] The highest altitude is outside the altitude range.
[0138] In some embodiments, the height thresholds may be the same or different in both the first height being higher than a height threshold and the first height being lower than a height threshold.
[0139] For example, the height threshold includes a first threshold and a second threshold, wherein the first threshold is greater than the second threshold. A first height higher than the height threshold includes: the first height is higher than the first threshold; a first height lower than the height threshold includes: the first height is lower than the second threshold.
[0140] For example, the height threshold can be determined based on predefined rules or indicated by the network device. For example, the network device can indicate the height threshold through SIB (e.g., SIB1, SIB19), or through RRC messages (e.g., RRC reconfiguration messages, RRC release messages, etc.). Of course, the height threshold can also be indicated through DCI, MAC CE, etc. This disclosure does not limit this.
[0141] In some embodiments, the height range may be determined based on at least one of the following: a lower height limit, an upper height limit, or a height value.
[0142] For example, the height range can be a range higher than the lower height limit; for example, the height range can be a range lower than the upper height limit; for example, the height range can be a range higher than the lower height limit and lower than the upper height limit; for example, the height range can be equal to the height value.
[0143] In some embodiments, the mapping relationship includes at least one of the following:
[0144] If the first height is higher than (or equal to) the height threshold, start the measurement of the NTN object, and / or stop the measurement of the TN object;
[0145] If the first height is lower than (or equal to) the height threshold, stop measuring the NTN object, and / or start measuring the TN object;
[0146] If the first height satisfies the height increment condition, start the measurement of the NTN object, and / or stop the measurement of the TN object;
[0147] If the first height satisfies the condition of decreasing height, stop measuring the NTN object and / or start measuring the TN object;
[0148] If the first altitude is within the altitude range, start measuring the NTN object associated with the altitude range;
[0149] If the first altitude is outside the altitude range, stop measuring the NTN object associated with the altitude range.
[0150] In some embodiments, the height threshold may be related to TN information.
[0151] For example, the closer a location is to the center of the TN, the higher the height threshold; conversely, the farther a location is from the center of the TN, the higher the height threshold.
[0152] For example, the height threshold corresponding to the first TN is relatively large, while the height threshold corresponding to the second TN is relatively small. For instance, the power of the signal transmitted by network devices in the first TN is greater than the power of the signal transmitted by network devices in the second TN.
[0153] In some embodiments, where NTN and TN operate at different frequencies, the object includes frequency points.
[0154] In some embodiments, when NTN and TN operate on the same frequency, the object includes the cell.
[0155] In some embodiments, taking NTN and TN frequency-differentiated deployment as an example, the mapping relationship may include enabling measurement of NTN frequency points and / or stopping measurement of TN frequency points when the first altitude is higher than (or equal to) a height threshold.
[0156] In this embodiment, when a terminal (e.g., a terminal residing in the TN) is at a relatively high first altitude (e.g., the first altitude is higher than the altitude threshold), it may have left the coverage area of the TN in the altitude direction. Therefore, the measurement of the NTN frequency point can be activated to determine a suitable NTN frequency point for access, thereby preventing the terminal from disconnecting from the network and ensuring the continuity of the terminal's communication services.
[0157] For example, the terminal can also stop measuring the TN frequency point, which helps to avoid power waste caused by the terminal continuing to measure the TN frequency point when it is outside the TN coverage area.
[0158] It should be noted that mapping relationships can be applied independently or in combination.
[0159] For example, taking NTN and TN frequency-differentiated deployment as an example, the mapping relationship may include starting the measurement of the NTN frequency point and / or stopping the measurement of the TN frequency point when the first altitude is higher than the altitude threshold, and may also include starting the measurement of the NTN frequency point and / or stopping the measurement of the TN frequency point when the first altitude meets the altitude increment requirement.
[0160] In this scenario, the terminal can determine whether the first altitude is higher than an altitude threshold and whether the first altitude satisfies altitude increment. Only if the first altitude is higher than the altitude threshold and altitude increment is satisfied (e.g., the terminal is in an aircraft during takeoff; or the terminal is a drone during takeoff) will the terminal initiate NTN frequency measurement and / or cease TN frequency measurement. This avoids erroneous operations caused by the terminal still being within the TN's altitude coverage area but the first altitude accidentally exceeding the altitude threshold.
[0161] In some embodiments, taking NTN and TN frequency-differentiated deployment as an example, the mapping relationship may include stopping the measurement of NTN frequency points and / or starting the measurement of TN frequency points when the first altitude is lower than (or equal to) a height threshold.
[0162] In this embodiment, when a terminal (e.g., a terminal residing in an NTN) is at a relatively low first altitude (e.g., the first altitude is below a height threshold), it may have already entered the coverage area of the TN in the altitude direction. Therefore, the measurement of the TN frequency point can be activated to determine a suitable TN frequency point for access, thereby ensuring the communication quality of the terminal.
[0163] For example, the terminal can also stop measuring the NTN frequency point, which helps to avoid power waste caused by the terminal continuing to measure the NTN frequency point when it is within the TN coverage area.
[0164] It should be noted that mapping relationships can be applied independently or in combination.
[0165] For example, taking NTN and TN frequency-differentiated deployment as an example, the mapping relationship may include starting the measurement of the TN frequency point and / or stopping the measurement of the NTN frequency point when the first altitude is lower than the altitude threshold, and may also include starting the measurement of the TN frequency point and / or stopping the measurement of the NTN frequency point when the first altitude meets the altitude decrease condition.
[0166] In this scenario, the terminal can determine whether the first altitude is below an altitude threshold and whether the first altitude meets the altitude reduction criteria. Only if the first altitude is below the altitude threshold and the altitude reduction criteria are met (e.g., the terminal is in an aircraft during landing; or the terminal is a drone during landing) will the terminal stop measuring the NTN frequency and / or begin measuring the TN frequency. This avoids erroneous operations caused by the terminal being outside the TN's coverage area in the altitude direction, even if the first altitude is accidentally below the altitude threshold.
[0167] In some embodiments, taking NTN and TN co-frequency deployment as an example, the mapping relationship may include enabling measurement of NTN cells and / or stopping measurement of TN cells when the first altitude is higher than (or equal to) an altitude threshold. For example, NTN cells and TN cells may be cells corresponding to the same frequency.
[0168] In this embodiment, when a terminal (e.g., a terminal camped in the TN) is at a relatively high first altitude (e.g., the first altitude is higher than the altitude threshold), it may have left the coverage area of the TN in the altitude direction. Therefore, the measurement of the NTN cell can be activated to determine a suitable NTN cell for access, thereby preventing the terminal from disconnecting from the network and ensuring the continuity of the terminal's communication services.
[0169] For example, the NTN cell to be measured may include at least one of the following: the NTN neighbor cell of the NTN serving cell where the terminal is located.
[0170] For example, the terminal can determine the NTN neighboring cells based on the information of the NTN neighboring cells. The information of the NTN neighboring cells may include at least one of the following: carrier frequency and physical cell identifier (PCI).
[0171] For example, NTN neighbor cell information can be carried in SIB19, such as in the NTN-NeighCellConfigList of SIB19. Cells in the NTN-NeighCellConfigList that are associated with ntn-config (NTN configuration, such as satellite auxiliary information) can be used as NTN neighbor cells, while cells in the NTN-NeighCellConfigList that are not associated with ntn-config can be used as TN neighbor cells.
[0172] For example, the terminal can also stop measuring TN cells, which helps to avoid power waste caused by the terminal continuing to measure TN cells when it is outside the TN coverage area.
[0173] It should be noted that mapping relationships can be applied independently or in combination.
[0174] For example, taking the co-frequency deployment of NTN and TN as an example, the mapping relationship may include enabling measurement of NTN cells and / or stopping measurement of TN cells when the first altitude is lower than the altitude threshold, and may also include enabling measurement of NTN cells and / or stopping measurement of TN cells when the first altitude meets the altitude increment requirement.
[0175] In this scenario, the terminal can determine whether the first altitude is higher than an altitude threshold and whether the first altitude satisfies altitude increment. Only if the first altitude is higher than the altitude threshold and altitude increment is satisfied (e.g., the terminal is in an aircraft during takeoff; or the terminal is a drone during takeoff) will the terminal initiate measurements of the NTN cell and / or cease measurements of the TN cell. This avoids erroneous operations caused by the terminal still being within the TN's coverage area in the altitude direction, even if the first altitude happens to be higher than the altitude threshold.
[0176] In some embodiments, taking NTN and TN co-frequency deployment as an example, the mapping relationship may include stopping measurements of NTN cells and / or enabling measurements of TN cells when the first altitude is lower than (or equal to) an altitude threshold. For example, NTN cells and TN cells may be cells corresponding to the same frequency.
[0177] In this embodiment, when a terminal (e.g., a terminal residing in an NTN) is at a relatively low first altitude (e.g., the first altitude is below a height threshold), since it may have already entered the coverage area of the TN in the altitude direction, the measurement of the TN cell can be activated to determine a suitable TN cell for access, thereby ensuring the communication quality of the terminal.
[0178] For example, the terminal can also stop measuring NTN cells, which helps to avoid power waste caused by the terminal continuing to measure NTN cells when it is within TN coverage area.
[0179] For example, the NTN cell to be measured may include at least one of the following: the NTN neighbor cell of the NTN serving cell where the terminal is located.
[0180] For example, the terminal can determine the NTN neighboring cells based on the information of the NTN neighboring cells. The information of the NTN neighboring cells may include at least one of the following: carrier frequency and physical cell identifier (PCI).
[0181] For example, NTN neighbor cell information can be carried in SIB19, such as in the NTN-NeighCellConfigList of SIB19. Cells in the NTN-NeighCellConfigList that are associated with ntn-config (NTN configuration, such as satellite auxiliary information) can be used as NTN neighbor cells, while cells in the NTN-NeighCellConfigList that are not associated with ntn-config can be used as TN neighbor cells.
[0182] It should be noted that mapping relationships can be applied independently or in combination.
[0183] For example, taking NTN and TN co-frequency deployment as an example, the mapping relationship may include starting measurement of TN cells and / or stopping measurement of NTN cells when the first altitude is lower than the altitude threshold, and may also include starting measurement of TN cells and / or stopping measurement of NTN cells when the first altitude meets the altitude reduction requirement.
[0184] In this scenario, the terminal can determine whether the first altitude is below an altitude threshold and whether the first altitude meets the altitude reduction criteria. Only if the first altitude is below the altitude threshold and the altitude reduction criteria are met (e.g., the terminal is in an aircraft during landing; or the terminal is a drone during landing) will the terminal initiate measurements of the NTN cell and / or cease measurements of the TN cell. This avoids erroneous operations caused by the terminal being outside the TN's coverage area in the altitude direction, even if the first altitude is accidentally below the altitude threshold.
[0185] In some embodiments, the height range is directly associated with the NTN object, or the height range is indirectly associated with the NTN object.
[0186] In some embodiments, the height range is indirectly associated with the NTN object, including:
[0187] The altitude range is associated with the satellite orbital altitude, and the satellite orbital altitude is associated with the NTN object.
[0188] In some embodiments, the height range is directly associated with the NTN object.
[0189] For example, taking an NTN object that includes NTN frequency points as an example, a height range can be associated with one or more NTN frequency points.
[0190] For example, multi-orbit NTN cells can be deployed on different frequencies. For instance, NTN cells in Medium Earth Orbit (MEO), Low Earth Orbit (LEO), and Geosynchronous Orbit (GEO) can be deployed using different frequencies. LEO, MEO, and GEO correspond to different altitude ranges.
[0191] For example, the altitude range can be further divided into multiple altitude ranges. For instance, the altitude range corresponding to LEO includes altitude ranges of 600km and 1200km, such as NTN cells on the 600km orbit and NTN cells on the 1200km orbit, which can be deployed using different frequency points.
[0192] For example, in the altitude range above LEO, network devices can be configured to associate frequencies with MEO NTN cells, and / or associate frequencies with GEO NTN cells.
[0193] For example, the terminal can determine the altitude range to which the first altitude belongs. If the first altitude is within the altitude range, it can determine that the first altitude belongs to the altitude range, and then perform measurements on the frequency points associated with the altitude range, without having to measure other frequency points. For example, if the first altitude belongs to the altitude range corresponding to GEO, the terminal can perform measurements on the frequency points corresponding to GEO, without having to measure other frequency points.
[0194] For example, a network device can indicate the frequency points associated with an altitude range through an SIB. The indicated content may include {altitude range, InterFreqCarrierFreqList}, where altitude range is the altitude range and InterFreqCarrierFreqList is the frequency points associated with the altitude range (e.g., a list of frequency points). For example, an SIB may include SIB4, through which the network device can indicate InterFreqCarrierFreqList, and the InterFreqCarrierFreqInfo in InterFreqCarrierFreqList indicates the altitude range as the altitude range associated with InterFreqCarrierFreqList.
[0195] For example, taking an NTN object that includes NTN cells as an example, a height range can be associated with one or more NTN cells.
[0196] For example, network devices can indicate cells associated with an altitude range via SIB. The indicated content may include {altitude range, neighborCellList}, where altitude range is the altitude range and neighborCellList is the cells associated with the altitude range (e.g., the NTN neighbor cell list).
[0197] In some embodiments, the height range is directly associated with the NTN object.
[0198] For example, taking an NTN object that includes NTN frequency points as an example, an altitude range can be associated with one or more satellite orbital altitudes (the altitude of the orbit where the NTN cell corresponds to the satellite), and the satellite orbital altitude is associated with the NTN frequency point.
[0199] For example, multi-track NTN cells can be deployed on different frequencies or on the same frequency. For example, for altitude ranges above LEO, network devices can be configured to associate with MEO track altitudes and / or GEO track altitudes. For example, for altitude ranges above MEO, network devices can be configured to associate with GEO track altitudes.
[0200] For example, the terminal can determine the altitude range to which a first altitude belongs. If the first altitude is within the altitude range, it can determine that the first altitude belongs to the altitude range, then determine the satellite orbit altitude associated with the altitude range, and subsequently measure the frequency points associated with the satellite orbit altitude, without needing to measure other frequency points. For example, if the first altitude belongs to the altitude range corresponding to GEO, and the satellite orbit altitude associated with this altitude range is the GEO orbit altitude, then the terminal can determine the frequency points associated with the GEO orbit altitude and measure those frequency points, without needing to measure other frequency points.
[0201] For example, network devices can use SIBs to indicate the satellite orbital altitudes associated with an altitude range. The indicated content may include {altitude range, orbitaAltitudeList}, where altitude range is the altitude range and satellite orbital altitudes are the satellite orbital altitudes associated with the altitude range (e.g., a list of satellite orbital altitudes).
[0202] The communication method involved in the embodiments of this disclosure may include at least one of steps S201 to S202. For example, step S201 may be implemented as a standalone embodiment, step S202 may be implemented as a standalone embodiment, and step S201+S202 may be implemented as a standalone embodiment, but is not limited thereto.
[0203] In some embodiments, steps S201 and S202 may be performed in an alternate order or simultaneously.
[0204] In some embodiments, step S201 is optional, and one or more of these steps may be omitted or substituted in different embodiments.
[0205] In some embodiments, step S202 is optional, and one or more of these steps may be omitted or substituted in different embodiments.
[0206] In some embodiments, if an arrow in the interaction diagram representing the sending of information, signaling, etc. from one subject to another passes through other subjects, it can be interpreted as the information being forwarded from one subject to another via other subjects, or it can be interpreted as the information being sent from one subject to another without passing through other subjects.
[0207] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.
[0208] The technical solutions of this disclosure will be further illustrated by several embodiments below:
[0209] Example 1: When the terminal height is greater than a predefined threshold, enable NTN measurement and / or stop TN measurement.
[0210] For example, in scenarios involving TN and NTN frequency distributions, a first altitude threshold can be introduced in the system message broadcast (e.g., SIB1 or SIB19) of the TN cell. For terminals camped in the TN cell, when their altitude exceeds the first altitude threshold (e.g., during aircraft takeoff) and / or when the terminal's altitude continues to increase, the terminal initiates NTN frequency measurement. Alternatively, the terminal can also stop measuring the TN frequency. For example, TN and NTN frequencies can be determined using specific frequency band identifiers defined by the protocol (e.g., ARFCN).
[0211] For example, in scenarios where TN and NTN are deployed on the same frequency, a first altitude threshold can be introduced in the system message broadcast of the TN cell. For terminals camped on the TN cell, when their altitude exceeds the first altitude threshold (e.g., during aircraft takeoff) and / or the terminal's altitude continues to increase, the terminal initiates NTN neighbor cell measurements. For example, the terminal can also stop measuring TN neighbor cells. NTN neighbor cell information (e.g., carrier frequency and PCI) can be determined through the NTN-NeighCellConfigList in SIB19; for example, neighbor cells associated with ntn-config (satellite auxiliary information) in the NTN-NeighCellConfigList are considered NTN neighbor cells.
[0212] For example, the first height threshold can also be configured via RRC-specific signaling, such as an RRC reconfiguration message or an RRC release message.
[0213] Example 2: When the height is less than a predefined height threshold, stop NTN measurement and / or start TN measurement.
[0214] For example, in scenarios involving TN and NTN frequency distributions, a second altitude threshold can be introduced in the system message broadcast (e.g., SIB1 or SIB19) of the TN cell. For terminals camped in the NTN cell, when their altitude is below the first altitude threshold (e.g., during aircraft landing) and / or when the terminal's altitude continues to decrease, the terminal initiates TN frequency measurement. Alternatively, the terminal can also stop NTN frequency measurement. TN and NTN frequencies can be determined using specific frequency band identifiers defined by the protocol (e.g., ARFCN).
[0215] For example, in scenarios where TN and NTN are deployed on the same frequency, a second altitude threshold can be introduced in the system message broadcast of the TN cell. For terminals camped on NTN cells, when their altitude is below the first altitude threshold (e.g., during aircraft landing) and / or the terminal's altitude continues to decrease, the terminal initiates TN neighbor cell measurements. For example, the terminal can also stop NTN neighbor cell measurements. NTN neighbor cell information (e.g., carrier frequency and PCI) can be determined using the NTN-NeighCellConfigList in SIB19. For example, neighbor cells associated with ntn-config (satellite auxiliary information) in the NTN-NeighCellConfigList are considered NTN neighbor cells. Neighbor cells not associated with ntn-config are considered TN neighbor cells.
[0216] For example, the second height threshold can also be configured via RRC-specific signaling, such as RRC reconfiguration messages or RRC release messages.
[0217] Example 3: For multi-orbit satellite scenarios, the terminal starts / stops the corresponding NTN frequency point / orbit altitude measurement based on the altitude range.
[0218] Example 3.1 (Associated Frequency Points):
[0219] For example, a terminal receives a system message broadcast, which indicates one or more altitude intervals. Each altitude interval contains one or two altitude thresholds. The altitude interval can include at least one of the following: less than one threshold, greater than one threshold, or between two thresholds. Each altitude interval can be associated with one or more frequency points.
[0220] This embodiment can be applied to scenarios where multi-track NTN cells are deployed using different frequencies, such as MEO and LEO track NTN cells deployed on different frequencies, or LEO NTN cells at altitudes of 600km and 1200km deployed on different frequencies. For example, in altitude ranges above LEO tracks, the network configuration can associate the frequencies of MEO NTN cells with and / or GEO NTN cells; for altitude ranges above MEO tracks, the network configuration can associate the frequencies of GEO NTN cells. The terminal determines the altitude range in which it is located and only enables measurement of one or more frequencies associated with that high-altitude range; frequencies not associated with that high-altitude range are not measured.
[0221] For example, one or more altitude ranges can be defined in SIB, and each altitude range displays an associated list of frequency points, namely {altitude range, InterFreqCarrierFreqList}.
[0222] For example, the associated height range is indicated in the InterFreqCarrierFreqInfo of the InterFreqCarrierFreqList in SIB4.
[0223] Example 3.2 (Associated Track Height):
[0224] For example, a terminal receives a system message broadcast, which indicates one or more altitude intervals. Each altitude interval contains one or two altitude thresholds. The altitude interval can include at least one of the following: less than one threshold, greater than one threshold, or between two thresholds. Each altitude interval is associated with one or more orbital altitudes, which refer to the orbital altitudes of the NTN neighboring cell satellites.
[0225] This embodiment can be applied to scenarios where multi-track NTN cells are deployed using the same frequency or different frequencies. Regarding the association between altitude ranges and track altitudes, for example, in altitude ranges above LEO tracks, the network configuration can associate them with MEO and / or GEO track altitudes; for altitude ranges above MEO tracks, the network configuration can associate them with GEO track altitudes. The terminal determines the altitude range in which it is located and only enables NTN cell measurements for one or more track altitudes associated with that altitude range; track altitudes not associated with that altitude range are not measured.
[0226] For example, one or more altitude ranges can be defined in SIB, each altitude range displaying an associated list of orbital altitudes, i.e., {altitude range, orbitaAltitudeList}.
[0227] Example 3.3 (Associated Cells):
[0228] For example, a terminal receives a system message broadcast indicating one or more altitude intervals. Each altitude interval contains one or two altitude thresholds. An altitude interval can include at least one of the following: less than one threshold, greater than one threshold, or between two thresholds. Each altitude interval is associated with one or more neighboring cells. The terminal determines the altitude interval in which its altitude falls and only initiates measurements on one or more neighboring cells associated with that altitude interval; neighboring cells not associated with that altitude interval may not be measured.
[0229] For example, one or more altitude ranges can be defined in SIB, and each altitude range displays an associated list of orbital altitudes, namely {altitude range, neighborCellList}.
