Description

[0001] This application is a divisional application of the invention patent application with the application date of August 3, 2020, application number 2020801010220, and name “Information reporting method, device, equipment and storage medium”. Technical Field

[0002] The present application relates to the field of wireless communication technology, and in particular to an information reporting method, device, equipment and storage medium. Background Art

[0003] In traditional terrestrial cellular systems, the coverage radius of the cell is small, and the difference between the signal propagation delay between the UE (User Equipment) and the base station of the serving cell and the signal propagation delay between the UE and the base station of the adjacent cell is very small. The difference in signal propagation delay between the UE and the base stations of different cells can be compensated by configuring the duration of SMTC (SS / PBCH block Measurement Timing Configuration), ensuring that the UE receives the SSB (Synchronization Signal Block) of different cells within the duration of SMTC. At the same time, by configuring the duration of the measurement interval, it is ensured that the UE's measurements on all hetero-frequency / hetero-technical frequency points are within the measurement interval.

[0004] However, in the NTN (Non Terrestrial Network) system, satellite communication is generally used to provide communication services to UE. Compared with cellular networks, NTN increases network coverage, but the signal propagation delay between UE and satellites in different cells also varies greatly.

[0036] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0037] Before introducing in detail the information reporting method provided in the embodiment of the present application, a brief introduction to the relevant terms and implementation environment involved in the embodiment of the present application is first given.

[0038] First, the relevant terms involved in this application are explained.

[0039] 1. NTN technology

[0040] At present, the Third Generation Partnership Project (3GPP) is studying NTN technology, which generally uses satellite communication to provide communication services to ground users. Compared with ground cellular network communication, satellite communication has many unique advantages. First, satellite communication is not limited by the user's geographical location. For example, general land communication cannot cover areas such as oceans, mountains, deserts, etc. where communication equipment cannot be set up or where communication coverage is not provided due to sparse population. For satellite communication, since one satellite can cover a large area of ​​land, and satellites can orbit the earth, in theory every corner of the earth can be covered by satellite communication. Secondly, satellite communication has great social value. Satellite communication can cover remote mountainous areas, poor and backward countries or regions at a low cost, so that people in these areas can enjoy advanced voice communication and mobile Internet technology, which is conducive to narrowing the digital divide with developed areas and promoting the development of these areas. Thirdly, satellite communication has a long distance, and the cost of communication does not increase significantly as the communication distance increases; finally, satellite communication has high stability and is not restricted by natural disasters.

[0041] According to the different orbital altitudes, communication satellites are divided into Low-Earth Orbit (LEO) satellites, Medium-Earth Orbit (MEO) satellites, Geostationary Earth Orbit (GEO) satellites, High Elliptical Orbit (HEO) satellites, etc. At the current stage, the main research is on LEO and GEO.

[0042] LEO

[0043] The altitude of low-orbit satellites ranges from 500km to 1500km, and the corresponding orbital period is about 1.5 hours to 2 hours. The signal propagation delay of single-hop communication between users is generally less than 20ms. The maximum satellite visibility time is 20 minutes. The signal propagation distance is short, the link loss is small, and the transmission power requirement for user terminals is not high.

[0044] GEO

[0045] The geosynchronous orbit satellite has an orbit altitude of 35786km and a rotation period around the earth of 24 hours. The signal propagation delay of single-hop communication between users is generally 250ms.

[0046] In order to ensure satellite coverage and improve the system capacity of the entire satellite communication system, satellites use multiple beams to cover the ground. A satellite can form dozens or even hundreds of beams to cover the ground; a satellite beam can cover a ground area with a diameter of tens to hundreds of kilometers.

[0047] There are at least two NTN scenarios: transparent load NTN and regenerative load NTN. Figure 1 The following figure shows the scenario of transparent transmission of NTN payload. Figure 2 A scenario of a regenerative load NTN is shown.

[0048] The NTN network consists of the following network elements:

[0049] One or more gateways to connect satellite and terrestrial public networks.

[0050] Feeder link: Link used for communication between the gateway and the satellite

[0051] Service link: the link used for communication between the terminal and the satellite

[0052] Satellite: Based on the functions they provide, they can be divided into two types: transparent payload and regenerative payload.

[0053] Transparent transmission payload: only provides the functions of wireless frequency filtering, frequency conversion and amplification. It only provides transparent forwarding of signals and does not change the waveform signal forwarded.

[0054] Regenerative load: In addition to providing wireless frequency filtering, frequency conversion and amplification functions, it can also provide demodulation / decoding, routing / conversion, encoding / modulation functions. It has some or all of the functions of a base station.

[0055] Inter-satellite links (ISL): exist in the regenerative load scenario.

[0056] 2. NR measurement

[0057] Measurement mainly refers to mobility measurement in the connected state. After the base station sends the measurement configuration to the UE, the UE detects the signal quality status of the neighboring cell according to the measurement object, reporting configuration and other parameters indicated in the measurement configuration, and feeds back the measurement reporting information to the base station for the base station to switch or improve the neighboring cell relationship list.

[0058] 1. Measurement configuration

[0059] In NR, the base station sends measurement configuration information to the UE in the connected state through RRC signaling. The UE performs measurements (same frequency, different frequency, different technology) according to the content of the measurement configuration information, and then reports the measurement results to the base station.

[0060] The base station uses RRC connection reconfiguration to perform measurement configuration. The measurement configuration information includes the following:

[0061] (1) Measurement Object

[0062] For intra-frequency measurement and inter-frequency measurement, each measurement object indicates the time-frequency position to be measured and the subcarrier spacing of the reference signal. For the cell related to the measurement object, the base station may configure a cell offset list.

[0063] For each measurement frequency, the network configures an SMTC to indicate the time when the UE receives SSB on the neighboring cell corresponding to the frequency. The SMTC configuration includes: the SMTC period, the start time offset of the SMTC within a period, the duration of the SMTC, etc.

[0064] (2) Reporting Configuration

[0065] Each measurement object corresponds to one or more reporting configurations. Reporting configurations include:

[0066] Reporting criteria: that is, the triggering condition for UE to perform measurement reporting, which can be periodic triggered reporting or event triggered reporting.

[0067] (3) Measurement Identity

[0068] A separate ID associates the measurement object with the reporting configuration. A measurement object can be associated with multiple reporting configurations at the same time, and a reporting configuration can also be associated with multiple measurement objects at the same time, distinguished by the measurement identifier.

[0069] (4) Measurement interval

[0070] Used to indicate the time when the UE performs inter-frequency / inter-system measurements. The UE performs inter-frequency / inter-system measurements during the measurement interval. The measurement interval configuration includes: the measurement interval period, the start time offset of the measurement interval within a period, and the duration of the measurement interval.

[0071] 2. Measurement reporting

[0072] The UE performs measurements according to the measurement configuration sent by the network, and evaluates the measurement report when certain trigger conditions are met. If the reporting conditions are met, the UE will fill in the measurement report and include it in the measurement report and send it to the network.

[0073] Next, the implementation environment involved in the embodiments of the present application is briefly introduced.

[0074] Currently, the measurement interval in the NR standard is based on UE configuration, and SMTC is based on frequency configuration.

[0075] Compared with the cellular network used by traditional NR, the signal propagation delay between UE and cell satellite in NTN is greatly increased. In addition, due to the large coverage area of ​​cell satellite, the signal propagation delay between UE and different cell satellites also varies greatly.

[0076] In NTN, in order for the UE to receive SSBs from different cell base stations within the SMTC window, the duration of SMTC needs to be significantly extended to compensate for the large differences between the UE and different cell base stations. At the same time, the duration of the measurement interval used by the UE to perform heterogeneous frequency / heterogeneous technology measurements also needs to be extended. The extension of the SMTC window means that the UE must continue to try to receive SSBs within a longer SMTC window, increasing the energy consumption of the UE. The extension of the measurement interval window means that the communication time between the UE and the serving cell base station is reduced, affecting the user experience.

[0077] Therefore, in order to more accurately configure the measurement interval for the adjacent cell and / or the SMTC offset value of the adjacent cell for the terminal, the serving cell base station needs to determine the signal propagation delay between the UE and the adjacent cell satellite, and then determine the communication delay between the UE and the satellites of different cells. According to the determined propagation delay, the measurement interval and / or the SMTC offset value of the adjacent cell is configured for the UE.

[0078] After introducing the relevant terms and implementation environment involved in the embodiments of the present application, the information reporting method provided in the embodiments of the present application will be introduced in conjunction with the accompanying drawings.

[0079] Figure 3 : is a flowchart of an information reporting method provided according to an exemplary embodiment of the present application, and the information reporting method may include the following contents:

[0080] Step 310: The UE reports a first timing deviation to the serving cell base station, wherein the first timing deviation is the difference between a first propagation delay and a second propagation delay, the first propagation delay is the propagation delay between the UE and the serving cell satellite, and the second propagation delay is the propagation delay between the UE and the adjacent cell satellite.

[0081] Among them, the UE can report the first timing deviation through an RRC (Radio Resource Control) message; it can also use a shared channel for reporting, and the UE's identification information can be carried when reporting based on the shared channel. The serving cell base station can determine the first timing deviation reported by the UE based on the identification information; the UE can also report the first timing deviation through resources configured by other serving cell base stations. The embodiment of the present application does not limit the reporting method of the UE reporting the first timing deviation.

[0082] In addition, when reporting the first timing deviation, the UE also reports the satellite identifier of the adjacent cell satellite corresponding to the first timing deviation, so that the serving cell base station can determine the first timing deviation corresponding to each adjacent cell satellite.

[0083] The first timing deviation reported by the UE is used for the serving cell base station to configure a first offset value of a measurement interval for a neighboring cell, and / or for the serving cell base station to configure a second offset value of an SMTC for a neighboring cell.

[0084] It should be noted that if the UE information reporting is periodic reporting, the periodic timer is started each time the UE reports the first timing deviation. When the periodic timer times out, the current timing deviation value of the adjacent cell satellite is reported again until the maximum number of periodic reports is reached or the serving cell base station deletes the timing deviation reporting configuration, and then the first timing deviation is no longer reported.

[0085] In an embodiment of the present application, the UE can determine the first timing deviation between the adjacent cell satellite and the serving cell satellite based on the first propagation delay between the UE and the serving cell satellite and the second propagation delay between the UE and the adjacent cell satellite, and report the first timing deviation to the serving cell base station to assist the serving cell base station in adjusting the subsequent UE measurement configuration information according to the first timing deviation.

[0086] Optionally, based on the above Figure 3 According to the information reporting method shown, the UE can also report the changing rule of the first timing deviation to the serving cell base station according to the determined first timing deviation.

[0087] See also Figure 4 , Figure 4 : is a flowchart of an information reporting method provided according to another exemplary embodiment of the present application, and the information reporting method may include the following contents:

[0088] Step 410: The UE reports the changing pattern of the first timing deviation to the serving cell base station.

[0089] The changing rule of the first timing deviation includes: a changing period and a changing step.

[0090] In one possible implementation, the mobile position of the UE in the serving cell does not change much, and the cell satellite is based on a fixed operation. In this case, during the operation cycle, the distance of the cell satellite relative to the UE in the cell may be constantly changing. The UE counts the first timing deviation within an operation cycle, determines the changing pattern of the first timing deviation within an operation cycle of the cell satellite, determines the changing cycle of the first timing deviation, and determines the changing step length within each changing cycle. The changing cycle and the changing step length are reported to the serving cell base station as the changing pattern of the first timing deviation. In this way, the serving cell base station can obtain the changing pattern of the first timing deviation of the UE within a changing cycle in one report, thereby reducing the signaling consumption of the UE and the serving cell base station for reporting the first timing deviation multiple times in the next repeated cycle.

[0091] In another possible implementation, not only the cell satellite is moving, but the UE is also moving. Then, based on the relative distance changes between multiple locations of the UE and the serving cell satellite over a period of time, the UE obtains at least one relative distance, determines the timing deviation corresponding to the at least one relative distance, and reports it to the serving cell base station as the variation rule of the first timing deviation over this period of time. In this way, when the UE's mobile position can be traced, the serving cell base station can obtain the variation rule of the first timing deviation over a period of time in one report, thereby reducing the signaling consumption of repeated reporting between the UE and the serving cell.

[0092] As an example, assume that the satellite movement cycle is 24 hours and there is an adjacent cell satellite. Therefore, the change of the first timing deviation in a change cycle is: between 1:00 and 6:00, the first timing deviation is 1ms, between 7:00 and 12:00, the first timing deviation is 2ms, between 13:00 and 18:00, the first timing deviation is 3ms, and between 19:00 and 24:00, the first timing deviation is 4ms. Then the change rule of the reported first timing deviation can be (6, 1), which is used to indicate that the change cycle of the timing deviation of the adjacent cell satellite is 6 hours, and the change step size in each change cycle is 1ms.

[0093] In addition, when reporting the variation pattern of the first timing deviation, the UE also reports the satellite identifier of the adjacent cell satellite corresponding to the variation pattern of the first timing deviation, so that the serving cell base station can determine the variation pattern of the first timing deviation corresponding to each adjacent cell satellite.

[0094] The change rule of the first timing deviation reported by the UE may also include other parameters. The above explanation is only given by taking the change period and the change step as an example, and does not constitute a limitation to the embodiments of the present application.

[0095] In the embodiment of the present application, the UE further determines the change rule of the first timing deviation based on multiple first timing deviations determined within a period of time, and reports the change rule of the first timing deviation to the serving cell base station. In this way, the signaling consumption generated by the UE repeatedly reporting to the serving cell base station can be reduced, and the serving cell base station can also obtain the change of the first timing deviation in one received message, and adjust the subsequent UE measurement configuration information according to the change rule of the first timing deviation.

[0096] It should be noted that the above Figure 3 and Figure 4 The information reporting process shown can be performed simultaneously or independently, and this application does not impose any restrictions on this.

[0097] That is, the UE can report the changing pattern of the first timing deviation while reporting the first timing deviation; it can also report the first timing deviation within a period of time and report the reporting pattern of the first timing deviation within another period of time; it can also fixedly report only the first timing deviation, or fixedly report only the changing pattern of the first timing deviation.

[0098] The reporting form of the UE may be determined from the reporting configuration sent to the UE by the serving cell base station, or may be a predefined reporting form. This embodiment of the present application does not limit this.

[0099] Optionally, based on the above Figure 3 or Figure 4 According to the information reporting method shown, the UE can report the first timing deviation or the change rule of the first timing deviation according to the measurement configuration of the serving cell base station.

[0100] See also Figure 5 , Figure 5 is a flowchart of a method for configuring measurement parameters according to an exemplary embodiment of the present application. The method for configuring measurement parameters may include at least part of the following contents:

[0101] Step 510: The serving cell base station sends measurement configuration to the UE.

[0102] The measurement configuration is used to instruct the UE to measure the first timing deviation according to the measurement configuration.

[0103] In the RRC connected state, the RRC context has been established, and the serving cell base station can send a measurement configuration to the UE in the connected state through RRC signaling, instructing the UE to measure the communication delay of the serving cell.

[0104] It should be noted that the measurement configuration may also be sent to the UE in other ways, such as an RRC release message during RRC state switching, cell broadcast, or other proprietary signaling, and this application does not impose any restrictions on this.

[0105] The measurement configuration sent by the serving cell base station includes at least one of the following measurement parameters:

[0106] ·Measurement object;

[0107] The measurement objects include: the identification and / or second ephemeris information of the satellite of the adjacent cell. Ephemeris refers to the precise position or trajectory table of the satellite running over time in the positioning measurement. The second ephemeris information includes the orbit and speed of the satellite of the adjacent cell. According to the second ephemeris information, the running position of the satellite of the adjacent cell at different times can be determined. The satellite of the adjacent cell can be one or more.

[0108] Report configuration;

[0109] Report configuration includes: one-time reporting or periodic reporting.

[0110] As an example, when the configured reporting mode is one-time reporting, the UE can report immediately after the measurement is completed, or it can report when the serving cell base station needs to report, and this application does not impose any restrictions on this.

[0111] As another example, when the configured reporting mode is periodic reporting, the UE reports according to a predetermined period, for example, reporting the measurement result once every 1 minute.

[0112] Optionally, the reporting period and the maximum number of periodic reports may also be configured, so that the UE can know the reporting interval and when the reporting ends.

[0113] For example, if the reporting period is 1 minute and the maximum number of periodic reports is 10 times, the UE reports the measurement result once every 1 minute and stops reporting after 10 times.

[0114] In addition, it should be noted that in step 510, the serving cell base station can configure corresponding reporting configurations for each adjacent cell satellite. In this way, the serving cell base station can receive different reporting parameters for different adjacent cell satellites to judge the communication delay and other information between the UE and each adjacent cell satellite. The serving cell base station can also configure a set of common reporting configurations for all adjacent cell satellites measured by the UE, so that the serving cell base station can determine the communication delay and other information between the UE and each adjacent cell satellite based on the same reporting type.

[0115] The embodiments of the present application do not limit the form of the reporting configuration configured by the serving cell base station for the UE. The UE can perform measurements and reports according to the measurement configuration. The reporting form and reporting time are not limited and can be pre-set according to requirements.

[0116] Step 520: The UE receives the measurement configuration of the serving cell base station.

[0117] The UE receives the RRC signaling sent by the serving cell base station, and parses it to determine the measurement configuration information configured for itself, wherein the measurement configuration information includes the object measured by the UE and the reporting format of the measurement result.

[0118] In an embodiment of the present application, the UE obtains the measurement configuration according to the RRC signaling sent by the serving cell base station, measures the measurement object according to the measurement configuration, and reports the measurement result to the serving cell base station according to the reporting configuration.

[0119] Optionally, based on the above Figure 3 or Figure 4 According to the information reporting method shown, the UE can calculate and determine the first timing deviation by itself, and then report the first timing deviation or the change rule of the first timing deviation to the serving cell base station.

[0120] See also Figure 6 , Figure 6 is a flowchart of a timing deviation determination method provided according to an exemplary embodiment of the present application. The timing deviation determination method may include at least part of the following contents:

[0121] Step 610: The UE calculates a first propagation delay from the UE to the serving cell satellite according to the first ephemeris information and the current position of the UE.

[0122] The first ephemeris information is the ephemeris information of the serving cell satellite, and includes information such as the orbit and speed of the serving cell satellite. According to the first ephemeris information, the operating position of the serving cell satellite at different times can be determined.

[0123] UE is a terminal with positioning function. When the positioning function is enabled on the terminal, the specific location of the current UE can be determined. The UE communicates with the serving cell satellite and the serving cell base station. After the UE is connected to the serving cell base station, the UE can save the first ephemeris information of the serving cell satellite.

[0124] In one possible implementation, the UE determines the current position of the serving cell satellite based on the first ephemeris information, and further determines a first distance between its own position and the current position of the serving cell satellite, and uses the ratio of the first distance to the speed of light as the first propagation delay from the UE to the serving cell satellite.

[0125] Step 620: The UE calculates a second propagation delay from the UE to the satellite of the adjacent cell according to the second ephemeris information and the current position of the UE.

[0126] The second ephemeris information is the ephemeris information of the satellite of the adjacent cell, and includes information such as the orbit and speed of at least one satellite of the adjacent cell. According to the second ephemeris information, the operating position of at least one satellite of the adjacent cell at different times can be determined.

[0127] It should be noted that, since the second ephemeris information includes information such as the orbit and speed of at least one adjacent cell satellite, the UE may need to measure the propagation delays of multiple adjacent cell satellites.

[0128] When there is one adjacent cell, the UE can determine the current position of the adjacent cell satellite based on the second ephemeris information, and further determine the second distance between its own position and the current position of the adjacent cell satellite, and use the ratio of the second distance to the speed of light as the second propagation delay from the UE to the adjacent cell satellite.

[0129] When there are N adjacent cells, and N is greater than 1, the UE determines the current positions of multiple adjacent cell satellites based on the second ephemeris information, and further determines the second distance between its own position and the current positions of the multiple adjacent cell satellites to obtain multiple second distances; and uses the ratio of the multiple second distances to the speed of light as the second propagation delay from the UE to the multiple adjacent cell satellites to obtain multiple second propagation delays.

[0130] Step 630: The UE calculates a first timing deviation according to the difference between the first propagation delay and the second propagation delay.

[0131] The first timing deviation is the communication delay between the UE and the satellite of the neighboring cell, which is offset from the communication delay between the UE and the satellite of the serving cell. That is, the first timing deviation reflects the communication delay of the UE after switching to the neighboring cell relative to the current serving cell.

[0132] It should be noted that the second propagation delay may be one or more, and therefore there may be the following two possible situations when determining the first timing deviation based on the first propagation delay and the second propagation delay.

[0133] When there is one adjacent cell, that is, there is one second propagation delay, the difference between the first propagation delay and the second propagation delay is directly determined, and the difference is used as the first timing deviation.

[0134] When there are N adjacent cells and N is greater than 1, that is, there are multiple second propagation delays, the UE determines the difference between the first propagation delay and the multiple second propagation delays, and obtains multiple first timing deviations, that is, the offset of the propagation delay between the UE and multiple adjacent cell satellites is determined.

[0135] In an embodiment of the present application, the UE can determine the distance between the UE and the serving cell satellite and at least one adjacent cell satellite based on the ephemeris information and the location information of its own location, and determine the propagation delay of the communication based on the distance, and then determine the propagation delay between the UE and different adjacent cell satellites.

[0136] Optionally, based on the above Figure 3-Figure 6 According to the method shown, the UE can measure the propagation delay between the UE and the serving cell satellite, and the adjacent cell satellite according to the measurement configuration configured by the serving cell base station, determine the first timing offset according to the propagation delay, and report the first timing offset to the serving cell base station.

[0137] Therefore, see Figure 7 , Figure 7 is a flowchart of an information reporting method provided according to another exemplary embodiment of the present application. The information reporting method may include at least part of the following contents:

[0138] Step 710: The serving cell base station sends measurement configuration to the UE.

[0139] The measurement configuration is used to instruct the UE to measure the first timing deviation according to the measurement configuration, and the measurement configuration includes at least one of the following measurement parameters:

[0140] Measurement object: the identification and / or second ephemeris information of the satellite of the adjacent cell. The second ephemeris information includes the orbit and speed of the satellite of the adjacent cell. According to the second ephemeris information, the operating position of the satellite of the adjacent cell at different times can be determined. The satellite of the adjacent cell can be one or more.

[0141] Report configuration: one-time report or periodic report.

[0142] In a possible implementation manner, the serving cell base station may send the measurement configuration to the corresponding UE through RRC signaling.

[0143] Step 720: The UE receives the measurement configuration of the serving cell base station.

[0144] The UE receives the RRC signaling sent by the serving cell base station, and parses it to determine the measurement configuration information configured for itself, wherein the measurement configuration information includes the object measured by the UE and the reporting format of the measurement result.

[0145] Step 730: The UE determines a first timing deviation according to the measurement configuration.

[0146] The UE determines the measurement object according to the measurement configuration, and the measurement object includes the second ephemeris information of at least one adjacent cell satellite. The second ephemeris information includes information such as the orbit and speed of the adjacent cell satellite, and the operating position of the adjacent cell satellite at different times can be determined according to the second ephemeris information.

[0147] UE is a terminal with positioning function. When the positioning function is enabled on the terminal, the specific location of the current UE can be determined. The UE communicates with the serving cell satellite and the serving cell base station. After the UE is connected to the serving cell base station, the UE can save the first ephemeris information of the serving cell satellite.

[0148] Therefore, in one possible implementation method, the implementation process of the UE measuring the first timing deviation according to the measurement configuration is: based on the first ephemeris information and the current position of the UE, the first propagation delay from the UE to the serving cell satellite is calculated, and then based on the second ephemeris information and the current position of the UE, the second propagation delay from the UE to the adjacent cell satellite is calculated, and then, based on the difference between the first propagation delay and the second propagation delay, the first timing deviation is calculated.

[0149] Step 740: The UE reports the first timing deviation to the serving cell base station.

[0150] The UE may report the first timing deviation via an RRC message; it may also use a shared channel for reporting, and the UE's identification information may be carried when reporting based on the shared channel. The serving cell base station may determine the first timing deviation reported by the UE based on the identification information; the UE may also report the first timing deviation through resources configured by other serving cell base stations. The embodiment of the present application does not limit the reporting method of the UE reporting the first timing deviation.

[0151] When reporting the first timing deviation, the UE also reports the satellite identifier of the adjacent cell satellite corresponding to the first timing deviation, so that the serving cell base station can determine the first timing deviation corresponding to each adjacent cell satellite.

[0152] Based on step 740, after multiple measurements, the UE can determine a change pattern of the first timing offset and report the change pattern to the serving cell base station.

[0153] That is, the above step 740 may also be replaced by: the UE reports the changing rule of the first timing deviation to the serving cell base station, where the changing rule includes: a changing period and a changing step length.

[0154] Similarly, when reporting the changing pattern of the first timing deviation, the UE also reports the satellite identifier of the adjacent cell satellite corresponding to the changing pattern of the first timing deviation, so that the serving cell base station can determine the changing pattern of the first timing deviation corresponding to each adjacent cell satellite.

[0155] It should be noted that the change rule of the first timing deviation reported by the UE may also include other parameters. The above explanation is only given by taking the change period and the change step as an example, and does not constitute a limitation to the embodiments of the present application.

[0156] Step 750: The serving cell base station receives the first timing deviation reported by the UE.

[0157] The first timing deviation is the difference between the first propagation delay and the second propagation delay, the first propagation delay is the propagation delay between the UE and the serving cell satellite, and the second propagation delay is the propagation delay between the UE and the adjacent cell satellite.

[0158] Optionally, the above step 750 may also be replaced by: receiving a change rule of the first timing deviation reported by the UE, where the change rule includes: a change period and a change step.

[0159] Step 760: The serving cell base station configures a first offset value of a measurement interval for a neighboring cell according to the first timing deviation, and / or configures a second offset value of a SMTC for a neighboring cell.

[0160] In the process of UE communicating through the service cell satellite and the service cell base station, the communication duration includes the communication duration on the service link and the communication duration on the feeder link. Therefore, in order to accurately configure the first offset value of the measurement interval for the adjacent cell, and / or configure the second offset value of the SMTC for the adjacent cell, not only the first timing deviation between the UE and the adjacent cell satellite should be considered, but also the second timing deviation between the adjacent cell satellite and the adjacent cell base station on the feeder link should be considered.

[0161] Among them, the second timing deviation is the difference between the third propagation delay and the fourth propagation delay, the third propagation delay is the propagation delay between the service cell satellite and the service cell base station on the feeder link, and the fourth propagation delay is the propagation delay between the adjacent cell satellite and the adjacent cell base station on the feeder link.

[0162] In a possible implementation, the implementation process of determining the second timing deviation may be: the serving cell base station calculates the third propagation delay from the serving cell base station to the serving cell satellite according to the first ephemeris information and its own current position, and then calculates the fourth propagation delay from the serving cell base station to the adjacent cell satellite according to the second ephemeris information and the current position of the serving cell base station, and then calculates the second timing deviation according to the difference between the third propagation delay and the fourth propagation delay. The sum of the first timing deviation and the at least one second timing deviation is determined as the communication delay deviation of the adjacent cell.

[0163] The first ephemeris information is the ephemeris information of the serving cell satellite, and the second ephemeris information is the ephemeris information of the adjacent cell satellite. The ephemeris information includes the orbit and speed of the cell satellite, and the operating position of the cell satellite at different times can be determined based on the ephemeris information.

[0164] It should be noted that what the UE measures and reports may be the first timing deviation or the changing pattern of the first timing deviation. Therefore, there are the following two possible implementation methods for determining the first offset value of the measurement interval of the adjacent cell and / or the second offset value of the SMTC.

[0165] In a possible implementation manner, the serving cell base station configures a first offset value of a measurement interval for a neighboring cell and / or configures a second offset value of a SMTC for a neighboring cell according to the first timing offset and the second timing offset.

[0166] In another possible implementation, the serving cell base station configures a first offset value for the measurement interval of the neighboring cell and / or configures a second offset value for the SMTC of the neighboring cell according to a variation rule of the first timing offset and the second timing offset.

[0167] As an example, when configuring the first offset value of the measurement interval for the adjacent cell, and / or configuring the second offset value of the SMTC for the adjacent cell, it should be ensured that the duration of the measurement interval and SMTC configuration is greater than the communication delay. That is, when the serving cell base station configures the first offset value of the measurement interval for the adjacent cell, it is necessary to increase the above-mentioned communication delay deviation on the basis of the measurement interval of the serving cell. Similarly, that is, when the serving cell base station configures the second offset value of the SMTC for the adjacent cell, it is necessary to increase the above-mentioned communication delay deviation on the basis of the offset value of the SMTC of the serving cell. In this way, the measurement effect of RRM can be guaranteed.

[0168] Optionally, based on the above step 760, since the satellite is moving, the relative distance between the serving cell satellite and the serving cell base station may also change, and the relative distance between the adjacent cell satellite and the adjacent cell base station may also change. Therefore, the serving cell base station can also determine the change pattern of the propagation delay on the adjacent cell satellite feed link based on the first ephemeris information and the second ephemeris information.

[0169] That is, the variation law of the propagation delay of the serving cell satellite on the feeder link is determined according to the first ephemeris information, and the variation law of the second propagation delay of the adjacent cell satellite on the feeder link is determined according to the second ephemeris information.

[0170] Further, the serving cell base station configures a first offset value of the measurement interval for the adjacent cell according to the variation rule of the first timing deviation and the second propagation delay reported by the UE, and / or configures a second offset value of the SMTC for the adjacent cell.

[0171] Alternatively, the serving cell base station configures a first offset value for the measurement interval of the adjacent cell according to the change rule of the first timing deviation and the change rule of the second propagation delay reported by the UE, and / or configures a second offset value for the SMTC of the adjacent cell.

[0172] In wireless communication systems, limited wireless resources need to be allocated and managed in order to optimize system performance and capacity. The allocation and management of wireless resources are usually performed based on the results of Radio Resource Management (RRM) measurements. RRM measurements require the configuration of corresponding measurement intervals, that is, the duration of the measurement interval and / or the duration of the SMTC needs to be determined so that the above duration is as small as possible, so as not to affect the data transmission efficiency during the measurement. However, in order to ensure the measurement effect, the above duration must ensure that the UE can measure the reference signal.

[0173] It should be noted that the present application is only to determine the first offset value of the measurement interval for the adjacent cell according to the first timing deviation reported by the UE, and / or to configure the second offset value of the SMTC for the adjacent cell. The RRM measurement process is not described in detail here.

[0174] In summary, in the method provided in the embodiment of the present application, the UE reports the first timing deviation to the serving cell base station, the first timing deviation is the difference between the first propagation delay and the second propagation delay, the first propagation delay is the propagation delay between the UE and the serving cell satellite, and the second propagation delay is the propagation delay between the UE and the adjacent cell satellite. That is, the UE can measure and determine the propagation delay of the adjacent cell satellite, and report the timing deviation of the adjacent cell satellite to the serving cell base station, so as to assist the serving cell base station to timely adjust the measurement interval configured for the adjacent cell and / or the offset value of the SMTC.
