Description

Technical Field

[0001] This application relates to the field of mobile communications, and in particular to a method, apparatus, and device for determining the time interval of a measurement interval in a non-terrestrial network (NTN). Background Technology

[0002] In New Radio (NR) systems, to better manage mobility, network devices are configured to allow terminals to perform same-frequency, different-frequency, or different-system measurements within specific time windows. These specific time windows are known as measurement intervals.

[0003] In NTN scenarios, satellites in different orbits have different transmission delays. When a terminal moves from a serving cell covered by the first satellite to a neighboring cell covered by the second satellite, the transmission delay between the two satellites will cause the terminal in the serving cell to miss the time window for SSB-based Measurement Timing Configuration (SMTC) or the measurement resources for Channel State Information Reference Signal (CSI-RS), thus preventing the terminal from completing the corresponding measurements of the neighboring cell.

[0036] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0037] The Third Generation Partnership Project (3GPP) is currently researching NTN technology, which typically uses satellite communication to provide communication services to terrestrial users. (Illustrative example follows.) Figure 1 As shown, in the NTN system, there are multiple satellites, each located in a different orbit. Each satellite covers one or more cells, and terminal 10 can move within a cell. For example, satellites 01, 02, and 03 are located in different orbits, and terminal 10 is located within the service cell covered by satellite 01.

[0038] To ensure satellite coverage, satellites typically use multiple beams to cover the ground. A single satellite can generate dozens or even hundreds of beams to cover the ground; a single satellite beam can cover a ground area with a diameter of tens to hundreds of kilometers. This results in a transmission delay difference between two satellites.

[0039] Combination Figure 1 and Figure 2Taking terminal 10 connecting to the first network device via satellite 01 as an example, satellite 01 corresponds to a second network device. When terminal 10 moves from the serving cell covered by satellite 01 to the neighboring cell 1 covered by satellite 02, due to the transmission delay difference between satellite 01 and satellite 02, there is a signal delay 1 between the measurement window configured by the first network device for terminal 10 and the measurement window received by terminal 10; or, there is a signal delay 2 between the SSB configuration window received by the terminal serving the second network device and the actually configured window.

[0040] In an NTN system, there are two scenarios: transparent payload NTN and regenerative payload NTN. Transparent payloads only provide wireless frequency filtering, frequency conversion, and amplification. They only provide transparent signal forwarding and do not alter the waveform of the forwarded signal. Regenerative payloads, in addition to providing wireless frequency filtering, frequency conversion, and amplification, can also provide demodulation / decoding, routing / conversion, and encoding / modulation functions.

[0041] As an illustration, an NTN network includes one or more gateways for connecting satellites and terrestrial public networks. The communication link between the gateway and the satellite is a feeder link, and the communication link between the terminal and the satellite is a service link.

[0042] In transparent payload NTN, terminals communicate with satellites via a service link, and network devices communicate with each other via a feeder link. In regenerative payloads, there is also a communication link between two satellites, which can be called an inter-satellite link.

[0043] In both NTN scenarios, network equipment can be base stations, which are devices used to provide wireless communication functions for terminals. Base stations can include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems employing different wireless access technologies, the names of devices with base station functions may differ. In this application embodiment, the devices that provide wireless communication functions for terminal 10 are collectively referred to as network equipment.

[0044] Figure 3 A flowchart illustrating a method for determining the measurement interval in an NTN according to an exemplary embodiment of this application is shown. This embodiment illustrates the application of this method in a terminal, and the method includes:

[0045] Step 3021: Obtain the location information of the satellites corresponding to neighboring cells.

[0046] Indicatively, the satellite's ephemeris information and at least one of its positioning, velocity, and timing (PVT) information carries the location information of the satellite corresponding to the neighboring cell.

[0047] The ephemeris information of a satellite refers to information related to its position, including but not limited to at least one of the following: satellite coordinates; satellite orbital altitude; position information of the nadir point; satellite orbital plane inclination; right ascension of the ascending node; length of the semi-major axis of the satellite orbit; eccentricity of the satellite orbit; perigee angular distance; and time of perigee passage. The PVT information of a satellite refers to at least one of the satellite's position, velocity, and timing information.

[0048] Step 3022: Obtain the configuration information for the measurement interval.

[0049] Schematic representation: The measurement gap refers to the period during which the terminal performs measurements. The configuration information for the measurement gap includes, but is not limited to, at least one of the following:

[0050] Measurement gap length (MGL);

[0051] Measurement Gap Repetition Period (MGRP);

[0052] Measurement Gap Timing Advance (MGTA);

[0053] Measurement interval time-domain offset.

[0054] This illustration shows that measurement interval configuration information is one type of measurement configuration information. Measurement configuration information refers to the measurement-related parameter information sent by the network device to the terminal. The terminal performs same-frequency, different-frequency, or different-technology measurements based on the received measurement configuration information and reports the measurement results to the network device. This illustration also shows that measurement configuration information includes, but is not limited to, at least one of the following: Measurement Object, Measurement Interval, Reporting Configuration, and Measurement Identity.

[0055] In the time determination method for measurement intervals in the NTN provided in this application embodiment, the measurement configuration information further includes the configuration information of the measurement object. Illustratively, the location information of the satellite corresponding to the neighboring cell is included in the configuration information of the measurement object. In an optional implementation, the terminal receives the measurement configuration information, which includes the configuration information of the measurement object and the configuration information of the measurement interval, wherein the configuration information of the measurement object includes the location information of the satellite corresponding to the neighboring cell.

[0056] For illustrative purposes, steps 3021 and 3022 can be executed simultaneously or at different times.

[0057] Step 304: Calculate the start time of the measurement interval based on the location information and the configuration information of the measurement interval.

[0058] As mentioned earlier, the measurement interval is the period during which the terminal performs measurements. Therefore, before the terminal performs measurements, it is necessary to calculate the start time of the measurement interval (Gap Staer Timing). That is, it is necessary to calculate the start time of the measurement period.

[0059] In the NTN scenario, due to the different transmission delays of satellites in different orbits, there is a transmission delay difference between the serving cell and the neighboring cells corresponding to the satellite. This transmission delay difference will prevent the terminal located in the serving cell from performing measurements on the neighboring cells.

[0060] In step 304, the terminal obtains the location information of the satellites corresponding to neighboring cells. Based on the location information of the satellites corresponding to the serving cell and the neighboring cells, the transmission delay difference between the serving cell and the neighboring cells can be calculated. Based on the transmission delay difference between the serving cell and the neighboring cells and the configuration information of the measurement interval, the terminal calculates the start time of the measurement interval. Subsequently, the terminal performs the measurement according to the start time.

[0061] In summary, the time determination method for measurement intervals in NTN provided in this application, by obtaining the location information of satellites corresponding to neighboring cells and the configuration information of measurement intervals, allows the terminal to calculate the start time of the measurement interval, thus avoiding interference caused by the transmission delay difference of satellites in different orbits, and enabling the terminal to complete the measurement within the specified time window.

[0062] Figure 4 A flowchart illustrating a method for determining the measurement interval in an NTN according to an exemplary embodiment of this application is shown. This embodiment illustrates the application of this method in a terminal, and the method includes:

[0063] Step 4021: Obtain the location information of the satellites corresponding to neighboring cells.

[0064] Indicatively, at least one of the satellite's ephemeris information and the satellite's PVT information carries the location information of the satellite corresponding to the neighboring cell.

[0065] Step 4022: Obtain the configuration information for the measurement interval.

[0066] The illustrative example shows that the measurement interval configuration information is one type of measurement configuration information. This measurement interval configuration information includes, but is not limited to, at least one of the following: MGL; MGRP; MGTA; and measurement interval time-domain offset.

[0067] In the time determination method for measurement intervals in the NTN provided in this application embodiment, the measurement configuration information also includes the configuration information of the measurement object. Illustratively, the location information of satellites corresponding to neighboring cells is included in the configuration information of the measurement object.

[0068] For illustrative purposes, steps 4021 and 4022 can be executed simultaneously or at different times.

[0069] Steps 4021 and 4022 are the same as steps 3021 and 3022 and can be used as a reference, so they will not be repeated here.

[0070] Step 403: Calculate the transmission delay difference between the serving cell and the neighboring cell based on the location information.

[0071] In this context, latency refers to the time it takes for a signal to be transmitted from the sending end to the receiving end. The latency difference is obtained by subtracting the minimum latency from the maximum latency. Illustratively, the transmission latency difference between the serving cell and the neighboring cell is the difference between the time it takes for the serving cell to receive the signal and the time it takes for the neighboring cell to receive the signal.

[0072] According to step 4021, the terminal obtains the location information of the satellites corresponding to the neighboring cells.

[0073] Since the terminal is located within the serving cell, it can also obtain the location information of the satellite corresponding to the serving cell. Based on the location information of the satellite corresponding to the serving cell and the location information of the satellite corresponding to the neighboring cells, the transmission delay difference between the serving cell and the neighboring cells is calculated.

[0074] Step 404: Calculate the start time of the measurement interval based on the configuration information of the measurement interval and the transmission delay difference.

[0075] As mentioned above, the configuration information for the measurement interval includes, but is not limited to, at least one of the following: MGL; MGRP; MGTA; and measurement interval time-domain offset.

[0076] After obtaining the configuration information of the measurement interval and calculating the transmission delay difference between the serving cell and the neighboring cell, the terminal calculates the start time of the interval based on the configuration information of the measurement interval and the transmission delay difference.

[0077] In summary, the method provided in this application calculates the transmission delay difference between the serving cell and the neighboring cell by obtaining the location information of the satellite corresponding to the neighboring cell, and calculates the start time of the measurement interval based on the transmission delay difference and the configuration information of the obtained measurement interval.

[0078] Figure 5 A flowchart illustrating a method for determining the measurement interval in an NTN according to an exemplary embodiment of this application is shown. This embodiment illustrates the application of this method in a terminal, and the method includes:

[0079] Step 501: Receive the configuration information of the measurement object.

[0080] As an illustration, the configuration information of the measurement object includes the location information of the satellites corresponding to neighboring cells.

[0081] As mentioned above, the configuration information of the measurement object is one type of measurement configuration information.

[0082] Among them, at least one of the satellite's ephemeris information and the satellite's PVT information carries the location information of the satellite corresponding to the neighboring cell.

[0083] Step 502: Obtain the configuration information for the measurement interval.

[0084] As mentioned above, the configuration information for the measurement interval is one type of measurement configuration information. This configuration information includes, but is not limited to, at least one of the following: MGL; MGRP; MGTA; and measurement interval time-domain offset.

[0085] For example, the terminal obtains the configuration information of the measurement interval, which includes the measurement interval time domain offset and MGTA.

[0086] For illustrative purposes, steps 501 and 502 can be executed simultaneously or at different times.

[0087] Step 503: Calculate the transmission delay difference between the serving cell and the neighboring cell based on the location information.

[0088] Indicatively, the transmission delay difference between the serving cell and the neighboring cell refers to the difference between the time it takes for the serving cell to receive a signal and the time it takes for the neighboring cell to receive a signal.

[0089] For illustrative purposes, steps 503 and 403 are the same and can be used as a reference, and will not be repeated here.

[0090] Step 504: Calculate the start time of the measurement interval based on the measurement interval time domain offset, MGTA, and transmission delay difference.

[0091] As mentioned above, after obtaining the configuration information of the measurement interval and calculating the transmission delay difference between the serving cell and the neighboring cell, the terminal calculates the start time of the calculation interval based on the configuration information of the measurement interval and the transmission delay difference.

[0092] When the configuration information of the measurement interval includes the measurement interval time-domain offset and MGTA, step 504 can be implemented in the following optional way: the start time of the measurement interval is obtained by subtracting the transmission delay difference from the sum of the measurement interval time-domain offset and MGTA.

[0093] This is equivalent to the start time of the measurement interval = measurement interval time domain offset + MGTA - transmission delay difference.

[0094] In summary, the method provided in this application allows the terminal to calculate the start time of the measurement interval based on the measurement interval time-domain offset, MGTA, and transmission delay difference.

[0095] Figure 6 A flowchart illustrating a method for transmitting measurement intervals in an NTN according to an exemplary embodiment of this application is shown. This embodiment illustrates the application of this method in a first network device, and the method includes:

[0096] Step 602: Obtain the location information of the satellites corresponding to neighboring cells.

[0097] Indicatively, at least one of the satellite's ephemeris information and the satellite's PVT information carries the location information of the satellite corresponding to the neighboring cell.

[0098] The ephemeris information of a satellite refers to information related to its position, including but not limited to at least one of the following: satellite coordinates; satellite orbital altitude; position information of the nadir point; satellite orbital plane inclination; right ascension of the ascending node; length of the semi-major axis of the satellite orbit; eccentricity of the satellite orbit; perigee angular distance; and time of perigee passage. The PVT information of a satellite refers to at least one of the satellite's position, velocity, and timing information.

[0099] Step 6041: Send location information to the terminal during the configuration of the measurement interval.

[0100] This is illustrative; the location information is used to calculate the start time of the measurement interval.

[0101] Step 6042: Send the measurement interval configuration information to the terminal during the measurement interval configuration process.

[0102] This is illustrative; the location information is used to calculate the start time of the measurement interval.

[0103] Schematic, the configuration information for the measurement interval includes, but is not limited to, at least one of the following: MGL; MGRP; MGTA; measurement interval time-domain offset.

[0104] As an illustration, steps 6041 and 6042 can be executed simultaneously or separately. That is, the location information and the measurement interval configuration information can be sent simultaneously or sequentially. For example, the location information can be sent first, followed by the measurement interval configuration information; or, the measurement interval configuration information can be sent first, followed by the location information.

[0105] Specifically, Figure 7 A flowchart illustrating a method for transmitting measurement intervals in an NTN according to an exemplary embodiment of this application is shown. This embodiment illustrates the application of this method in a first network device, and the method includes:

[0106] Step 702: Obtain the location information of the satellite corresponding to the neighboring cell from the second network device of the neighboring cell through the first interface.

[0107] In illustrative terms, the first interface is the network interface between the first network device and the second network device.

[0108] Optionally, the first interface is the Xn interface.

[0109] In illustrative terms, the first network device and the second network device correspond to different cells. Specifically, the first network device corresponds to the serving cell, and the second network device corresponds to the neighboring cell.

[0110] Step 703: Send the configuration information of the measurement object to the terminal during the configuration of the measurement interval.

[0111] As an illustration, the configuration information of the measurement object includes location information. This location information is used to calculate the start time of the measurement interval.

[0112] Step 704: During the configuration of the measurement interval, send the measurement interval time domain offset and MGTA to the terminal.

[0113] Indicatively, when the configuration information for the measurement interval includes the measurement interval time-domain offset and MGTA, the first network device sends the aforementioned two parameter information to the terminal.

[0114] For illustrative purposes, steps 703 and 704 can be executed simultaneously or at different times.

[0115] In summary, the embodiments of this application provide a method that, by sending the location information of satellites corresponding to neighboring cells and the configuration information of measurement intervals, enables a terminal to calculate the start time of the measurement interval based on the information sent by the first network device.

[0116] Combination Figure 8 This application provides a flowchart of a method for transmitting and determining the time of measurement intervals in an NTN. Taking the configuration information of the measurement interval, including the time-domain offset and MGTA, as an example, the method includes:

[0117] Step 801: The first network device obtains the location information of the satellite corresponding to the neighboring cell.

[0118] Indicatively, at least one of the satellite's ephemeris information and the satellite's PVT information carries the location information of the satellite corresponding to the neighboring cell.

[0119] Specifically, the first network device can obtain location information from the second network device in a neighboring cell. Illustratively, the first network device obtains location information through the Xn interface.

[0120] For example, location information is included in the satellite's ephemeris information. The first network device obtains the ephemeris information of the satellite corresponding to the neighboring cell from the second network device in the neighboring cell, and obtains the satellite's location information based on the ephemeris information.

[0121] For example, location information is included in the PVT information of a satellite. The first network device obtains the PVT information of the satellite corresponding to the neighboring cell from the second network device of the neighboring cell, and obtains the satellite's location information based on the PVT information.

[0122] Step 8021: The first network device sends location information to the terminal during the configuration of the measurement interval.

[0123] This is illustrative; the location information is used to calculate the start time of the measurement interval.

[0124] As mentioned above, location information can be carried in the configuration information of the measured object. Therefore, step 8021 can be implemented in the following optional way:

[0125] During the configuration of the measurement interval, the first network device sends the configuration information of the measurement object to the terminal, which includes location information.

[0126] Step 8022: During the configuration of the measurement interval, the first network device sends the measurement interval time domain offset and MGTA to the terminal.

[0127] As mentioned above, the measurement interval time-domain offset and MGTA are included in the configuration information of the measurement interval. Therefore, step 8022 can be implemented in the following optional manner:

[0128] During the configuration of the measurement interval, the first network device sends the measurement interval configuration information to the terminal. The measurement interval configuration information includes the measurement interval time domain offset and MGTA.

[0129] For illustrative purposes, steps 8021 and 8022 can be executed simultaneously or at different times.

[0130] Step 803: The terminal acquires the location information of the satellites corresponding to the neighboring cells, the time-domain offset of the measurement interval, and the MGTA.

[0131] As an illustration, location information, measurement interval time-domain offset, and MGTA can be acquired by the terminal simultaneously or at different times.

[0132] Step 804: The terminal calculates the transmission delay difference between the serving cell and the neighboring cell based on the location information.

[0133] After obtaining the location information of the satellites corresponding to the neighboring cells, the terminal can calculate the transmission delay difference between the serving cell and the neighboring cells based on the location information of the satellites corresponding to the serving cell.

[0134] Step 805: The terminal calculates the start time of the measurement interval based on the measurement interval time domain offset, MGTA, and transmission delay difference.

[0135] After calculating the transmission delay difference, the terminal subtracts the transmission delay difference from the sum of the measurement interval time-domain offset and MGTA to obtain the start time of the measurement interval. That is, the start time of the measurement interval = measurement interval time-domain offset + MGTA - transmission delay difference.

[0136] As an illustration, the various methods for determining the measurement interval and the various transmission methods provided above in NTN can be implemented in combination. For example, [the following can be used as an example:] Figure 7 The method for transmitting measurement intervals shown in the figure and Figure 5 The time determination method shown in the figure is implemented in combination so that the terminal calculates the start time of the measurement interval based on the acquired information.

[0137] In summary, the method provided in this application embodiment sends the location information of the satellite corresponding to the neighboring cell and the configuration information of the measurement interval through the first network device, so that the terminal can calculate the start time of the measurement interval based on the information sent by the first network device.
