The word "if' as used herein means "when" or "upon" or "in response to the determination" depending on the context.

[0033] Reference is made to Figure 1 which shows a structure diagram of a wireless communication system provided by the embodiments of the disclosure. As shown in Figure 1 , the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system can include a plurality of UEs 11 and a plurality of base stations 12.

[0034] The UE 11 can be a device that provides voice and / or data connectivity to a user. The UE 11 can be a machine-to-machine UE, such as a sensor device, a mobile telephone (also known as a "cellular" telephone), and computers with a mobile-telephone capability, e.g., a fixed, portable, pocket, handheld, computer-embedded, or car-mounted devices. For example, the UE 11 can be a Station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote UE, an access UE, a user terminal, a user agent, a user device, or a user equipment (UE). Alternatively, the UE 11 can be a device of an unmanned aerial vehicle. Alternatively, the UE 11 can be a vehicle-mounted device, e.g., a car-mounted device with a wireless communication function, or a wireless communication device externally connected to a car-mounted device. Alternatively, the UE 11 can be a roadside device, e.g., a street lamp, a signal lamp, or other roadside device with a wireless communication function.

[0035] The base station 12 can be a network-side device in a wireless communication system. The wireless communication system can be a 4th generation mobile communication (4G) system, also known as a Long Term Evolution (LTE) system, or a 5G system, also known as a new radio (NR) system or a 5G NR system. Alternatively, the wireless communication system can be a next-generation system of the 5G system. In the 5G system, the access network can be referred to as a New Generation-Radio Access Network (NG-RAN). Alternatively, the wireless communication system can be an MTC system.

[0036] The base station 12 can be an evolved NodeB (eNB) in a 4G system. Alternatively, the base station 12 can be a base station (gNB) in a 5G system using a centralized and distributed architecture. When the base station 12 uses a centralized and distributed architecture, it generally includes a central unit (CU) and at least two distributed units (DUs). The central unit is provided with a protocol stack of a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, and a media access control (MAC) layer; and the distributed unit is provided with a protocol stack of a physical (PHY) layer. The specific implementation of the base station 12 is not limited in the embodiments of the present disclosure.

[0037] The base station 12 and the UE 11 can establish a wireless connection through a wireless air interface. In different embodiments, the wireless air interface is based on a fourth generation mobile communication network technology (4G) standard; or the wireless air interface is based on a fifth generation mobile communication network technology (5G) standard, such as the wireless air interface is a new air interface; or the wireless air interface can also be based on a more next generation mobile communication network technology standard of 5G.

[0038] In some embodiments, the UEs 11 can also establish an E2E (End to End) connection. For example, V2V (vehicle to vehicle) communication, V2I (vehicle to infrastructure) communication, and V2P (vehicle to pedestrian) communication in vehicle to everything (V2X) communication, and the like.

[0039] In some embodiments, the wireless communication system can also include a network management device 13.

[0040] A plurality of base stations 12 are connected to a network management device 13. The network management device 13 can be a core network device in a wireless communication system, for example, the network management device 13 can be a mobility management entity (MME) in an evolved packet core (EPC). Alternatively, the network management device can also be other core network devices, such as a serving gateway (SGW), a public data network gateway (PGW), a policy and charging rules function (PCRF), or a home subscriber server (HSS), etc. The implementation form of the network management device 13 is not limited in the embodiments of the present disclosure.

[0041] In a terrestrial network (TN) TN system, the cell radius is small, and the transmission delay difference between UEs and different cells is very small, much smaller than the length of the SMTC window / measurement gap. However, in an NTN system, due to the large cell radius, the overlapping range of different satellite coverage areas is also large. When a satellite (SA) 1 provides services for a UE, the UE can also be in the coverage of a satellite 2 / satellite 3. Considering the mobility of the UE, the UE needs to perform measurements on the neighboring cells covered by the satellite 2 or satellite 3, and the influence of the transmission delay difference needs to be considered. As shown in the following figure: Figure 2 The transmission delay of the UE receiving the service cell signal can be represented as T1g (feeder link transmission delay) + T1u (service link transmission delay), and the transmission delay of the UE receiving the neighbor cell signal is T2u + T2g. The transmission delay difference is T1g + T1u - (T2g + T2u). Considering that the distances between different satellites and the UE and the ground station are different, the transmission delay between the UE receiving the service cell signal and the UE receiving the neighbor cell signal will have a large difference, that is, T1g + T1u - (T2g + T2u) will not tend to 0, and can be greater than the time length of the SMTC window / measurement gap.

[0042] If the SMTC window / measurement gap configuration does not consider the transmission delay difference, the UE can miss the SSB / CSI-RS measurement window, and therefore will not be able to perform measurements on the configured reference signals.

[0043] AsFigure 3 As shown, the embodiment of the present disclosure provides a period configuration updating method for measuring a time period of an SSB, applied to a terminal, and the method comprises:

[0044] S110: detecting an SSB of a neighbor cell in a time period for measuring the SSB, wherein the time period for measuring the SSB comprises an SMTC window and / or a measurement gap;

[0045] S120: reporting updating indication information according to a detection result of the SSB, wherein the updating indication information is used for updating a period configuration at a network side; and the period configuration comprises indication information used for determining the time period for measuring the SSB.

[0046] In the embodiment of the present disclosure, the configuration method for the time period for measuring an SSB can be applied to various types of terminals, including but not limited to a mobile phone, a tablet computer, a wearable device, a vehicle-mounted device, or various types of smart devices. The smart devices include but are not limited to smart home devices, smart office devices, or smart teaching devices.

[0047] In the embodiment of the present disclosure, the terminal can be a terminal capable of accessing an NTN cell, for example, a satellite communication terminal. Of course, in some cases, some terminals support TN cell and NTN cell communication at the same time. The NTN cell is a communication cell in an NTN system. The TN cell can include a cell formed by a ground base station.

[0048] In the embodiment of the present disclosure, the neighbor cell can be an NTN cell of a serving cell. Here, the serving cell can also be an NTN cell or a TN cell.

[0049] In the embodiment of the present disclosure, the terminal will determine the time period for measuring the SSB according to the received period configuration used for determining the time period for measuring the SSB, for example, determine the distribution position of the time period for measuring the SSB in the time domain, and / or the time length of the time period for measuring the SSB.

[0050] In the time period for measuring the SSB determined according to the period configuration, the SSB of the neighbor cell is detected to obtain a detection result of whether the SSB of the neighbor cell is successfully detected. If the time period for measuring the SSB is an SMTC window, the corresponding period configuration can be an SMTC configuration.

[0051] If the time period for measuring the SSB is a measurement gap, the corresponding period configuration can be a measurement gap configuration.

[0052] Exemplarily, the detection result can at least indicate whether the SSB of the corresponding neighbor cell is detected.

[0053] Exemplarily, the detection result can indicate, while indicating whether the SSB of the corresponding neighbor cell is detected, the number of SSBs detected in the time period of measuring SSBs determined according to the current time period configuration, and / or the reference signal receiving power (RSRP) of the SSB and the reference signal receiving quality (RSRQ) of the SSB.

[0054] According to the detection result, whether the time period of measuring SSBs can meet the measurement requirement of the SSB of the neighbor cell can be determined, and then whether the current time period configuration needs to be updated can be determined according to the measurement requirement.

[0055] The terminal can receive a neighbor cell list from a serving cell of the terminal, the neighbor cell list having a cell identity of a neighbor cell.

[0056] When the SSB of the neighbor cell is detected in the time period of measuring SSBs, whether the terminal has not detected the SSB of one or more neighbor cells can be determined according to the cell identity in the neighbor cell list.

[0057] In an embodiment, the SSB can include a primary synchronization signal.

[0058] In another embodiment, the SSB includes a primary synchronization signal and a secondary synchronization signal.

[0059] In yet another embodiment, the SSB includes a primary synchronization signal, a secondary synchronization signal, and a physical broadcast channel (PBCH).

[0060] In the embodiments of the present disclosure, when the terminal performs SSB measurement of a neighbor cell and finds that the SSB of at least one neighbor cell fails to be detected according to the detection result, it indicates that the current time period of measuring SSBs can not be suitable for the measurement of the neighbor cell by the terminal. In order to realize successful detection of the SSB of the neighbor cell, update indication information can be reported according to the detection result of the SSB. In this way, after the network side receives the update indication information, the time period configuration of the time period of measuring SSBs can be updated under the trigger of the update indication information or according to the information content of the update indication information.

[0061] In an embodiment, the update indication information can be only an update instruction. After the network side receives the update instruction, it is determined that the time period of measuring SSBs needs to be updated, and how to update and the basis of the update can be determined according to a preset update strategy, for example, increasing the time period of measuring SSBs by a preset step length.

[0062] In another embodiment, the update indication information carries a transmission delay difference. The transmission delay difference can include:

[0063] a first transmission delay difference; the first transmission delay difference is a difference between a transmission delay between the terminal and the serving cell and a transmission delay between the terminal and each of the neighbor cells in the neighbor cell group in which the neighbor cell of SSB detection failure is located;

[0064] and / or,

[0065] a second transmission delay difference; the second transmission delay difference is a difference between a transmission delay between the terminal and the serving cell and a transmission delay between the terminal and each of the neighbor cells in the neighbor cell group in which the neighbor cell of SSB detection success is located.

[0066] That is, in one embodiment, the S120 can include: determining a transmission delay difference between the terminal and the transmission of the serving cell and the neighbor cell according to the detection result of the SSB; and reporting the update indication information according to the transmission delay difference.

[0067] Exemplarily, the content of the update indication information can be various, including but not limited to at least one of the following:

[0068] a cell identifier and a transmission delay difference of the neighbor cell of SSB detection failure;

[0069] a bit map and a transmission delay difference, different bits in the bit map indicating different neighbor cells. In one embodiment, the transmission delay difference carried by the update indication information can be the first transmission delay difference.

[0070] Of course, the above is only an example of the content of the update indication information, and the specific implementation is not limited thereto.

[0071] The time period of the SSB to be updated for measurement herein includes but is not limited to: a time length of the time period of the SSB to be updated for measurement and / or a time domain position of the time period of the SSB to be updated for measurement, etc.

[0072] After the time period configuration is updated, the serving cell can send the updated time period configuration to the terminal in a manner of broadcast, multicast or unicast. Exemplarily, the serving cell can send the time period configuration to the terminal through RRC signaling.

[0073] In the embodiments of the present disclosure, the time period of the SSB to be measured can be divided into two types, one is SMTC window, and the other is measurement gap.

[0074] The SMTC window is that when the serving cell and the neighbor cell use the same frequency band, i.e., the serving cell and the neighbor cell are the same frequency cells, the terminal can perform SSB measurement of the neighbor cell in the SMTC window. If the serving cell and the neighbor cell are different frequency cells, the terminal may also need to involve the change of the antenna parameter when performing SSB measurement of the neighbor cell, and therefore the time period for measuring the SSB includes a measurement gap and a corresponding SMTC window which are longer than the time length of the SMTC window. When the serving cell and the neighbor cell are different frequency cells, the terminal performs SSB measurement of the neighbor cell in the SMTC window included in the measurement gap. In the different frequency system, the measurement gap can include one or more SMTC windows.

[0075] In summary, in the embodiments of the present disclosure, the update indication information is reported according to the detection result of the SSB of the neighbor cell, and the network side is triggered to update the time period for measuring the SSB as necessary, thereby reducing unnecessary update of the time period for measuring the SSB, reducing signaling consumption caused by frequent update of the time period for measuring the SSB, and reducing the phenomenon of SSB detection failure of the neighbor cell or resource waste caused by too long or too short fixed setting of the time period for measuring the SSB.

[0076] At the same time, the update of the time period for measuring the SSB involves the interaction between the terminal and the base station, and therefore the time period for measuring the SSB is not unidirectional update, thereby reducing the time period for measuring the SSB which is formed by the terminal for updating the time period for measuring the SSB and does not adapt to the current communication scenario. Therefore, the update method of the time period for measuring the SSB provided by the embodiments of the present disclosure has the characteristics of small signaling overhead and the setting of the time period for measuring the SSB meeting the SSB measurement requirement of the current neighbor cell.

[0077] In some embodiments, the S120 can include:

[0078] The update indication information is reported in response to the detection result of the SSB, at least one SSB of the neighbor cell failing to be detected.

[0079] In the case that at least one SSB of the neighbor cell fails to be detected, it can be considered that the terminal does not detect the SSB transmitted by at least one neighbor cell, and therefore there may be an inappropriate phenomenon in the current setting of the time period for measuring the SSB. In order to successfully detect the SSB of the neighbor cell, the terminal can report the update indication information according to the detection result, so as to trigger the network side (the network side at this time includes but is not limited to the serving cell) to update the configuration of the time period for measuring the SSB, and then the terminal can re-determine the time period for measuring the SSB according to the updated configuration of the time period for measuring the SSB. In the updated time period for measuring the SSB, the SSB of the neighbor cell is measured, and there is a high probability that the SSB of each neighbor cell which needs to be detected can be successfully detected.

[0080] Exemplarily, if the update indication information carries the second transmission delay difference, S120 can comprise: determining, according to the detection result, that SSB detection of at least one neighboring cell fails.

[0081] In one embodiment, the method further comprises:

[0082] In response to determining, according to the detection result of the SSB, that the terminal successfully detects SSBs of all neighboring cells, the update indication information is not reported, i.e., the reporting of the update indication information is stopped or shielded, thereby reducing unnecessary signaling overhead.

[0083] In one embodiment, as Figure 4 indicated, S120 can comprise:

[0084] S121: in response to the time period configuration not being an initial time period configuration, determining, according to the detection result of the SSB, a first transmission delay difference between transmission of the terminal and the serving cell and transmission of the terminal and at least one neighboring cell whose SSB detection fails, respectively;

[0085] S122: reporting the update indication information according to the first transmission delay difference.

[0086] The initial time period configuration can be a first time period configuration for determining SSBs that is issued by the network side to the terminal.

[0087] Exemplarily, according to the time period configuration of the first time period for measuring SSBs obtained by the terminal after entering the current serving cell, the time period configuration can be divided into an initial time period configuration and a non-initial time period configuration. The initial time period configuration is the first time period configuration for measuring SSBs obtained by the terminal after entering the serving cell, and time period configurations after the first time period configuration are all non-initial time period configurations.

[0088] Exemplarily, the initial time period configuration can be a time period configuration broadcast by the serving cell.

[0089] If the time period configuration of the time period for measuring SSBs currently used by the terminal after entering the serving cell is not the initial time period configuration, it indicates that the terminal has known which neighboring cells of the current serving cell.

[0090] If the current base station stores each transmission delay difference of the time period for measuring SSBs currently applied, and the transmission delay difference (i.e., the first transmission delay difference) between transmission of the terminal and the serving cell and transmission of the terminal and the neighboring cell whose SSB detection fails is reported to the base station, the base station can update the time period for measuring SSBs according to the transmission delay difference between transmission of the terminal and the serving cell and the neighboring cell stored previously and the first transmission delay difference currently reported.

[0091] Here, the transmission delay difference can be one of:

[0092] a difference between a transmission delay of the terminal to the neighbor cell and a transmission delay of the terminal to the serving cell;

[0093] a difference between a transmission delay of the terminal to the serving cell and a transmission delay of the terminal to the neighbor cell;

[0094] In an embodiment, the update indication information can not carry any information of the neighbor cell, such as a cell identity of the neighbor cell, which directly or indirectly indicates the SSB detection failure of the neighbor cell. Of course, this is only an example of the update indication information, and the specific implementation is not limited to this example.

[0095] In an embodiment, S120 can directly include: determining, according to the detection result of the SSB, at least a first transmission delay difference between a transmission of the terminal to the serving cell and a transmission of the terminal to the SSB detection failure neighbor cell; and reporting the update indication information according to the first transmission delay difference.

[0096] For example, the process of configuring and issuing the cell list of the neighbor cell of the serving cell on the initial time period, in this case, the terminal gets the initial time period configuration after entering the serving cell, and can also determine which neighbor cell SSB detection fails.

[0097] That is, in some cases, the terminal does not need to determine whether the currently used time period configuration is the initial time period configuration.

[0098] In an embodiment, the method further includes:

[0099] detecting the SSB of the same neighbor cell in the time period of measuring the SSB for M times in succession, determining that the detection result of the SSB corresponding to the neighbor cell is failure; wherein, the M is any positive integer.

[0100] In order to ensure the accuracy of the detection result, in the embodiment of the present disclosure, the terminal no longer determines that the SSB detection of the neighbor cell fails once, but determines that the SSB detection of the neighbor cell fails after M times of SSB detection failure.

[0101] Of course, in another embodiment, the terminal can determine that the SSB detection of the neighbor cell fails in one detection process of the neighbor cell.

[0102] In an embodiment, the method further includes:

[0103] determining a SSB detection failure when N SSBs are not successfully detected in the SSB measurement period; and / or determining a SSB detection success when N SSBs are successfully detected in the SSB measurement period.

[0104] wherein the N is less than or equal to a total number of SSBs configured for the corresponding neighbor cell in the SSB measurement period.

[0105] The SSB detection for a neighbor cell is SSB detection in an SSB measurement period, detecting each SSB in an SSB burst or SSB burst set. One SSB burst includes one or more SSBs.

[0106] In one measurement, if N SSBs are successfully detected, the measurement is considered successful. N can be less than a total number of SSBs configured in the SSB burst.

[0107] In this way, the detection result of the SSB for the neighbor cell can be further refined.

[0108] In one embodiment, the S121 can include:

[0109] According to the period configuration and the first transmission delay difference, the update indication information is reported.

[0110] The SSB measurement period has different types of configurations, which can be divided into different granularity period configurations according to the range of action.

[0111] The common period configuration is for all neighbor cells of the serving cell.

[0112] The group period configuration is for one neighbor cell group of the serving cell, and one neighbor cell group includes one or more neighbor cells.

[0113] The cell period configuration is for a single neighbor cell of the serving cell.

[0114] Due to the different types of period configurations, the information content of the update indication information can be different. Through the differentiation of the information content of the update indication information, the base station can quickly and specifically update the SSB measurement period of the neighbor cell after receiving the update indication information.

[0115] In one embodiment, the updating of the period configuration of the SSB measurement period of the neighbor cell corresponding to the first transmission delay difference according to the type of the period configuration corresponding to the first transmission delay difference includes at least one of:

[0116] In response to the time period configuration being a common time period configuration, the updated indication information indicating a first time delay difference range is reported according to the first transmission time delay difference, wherein the common time period configuration determines a time period of measuring SSBs that is used for SSB measurement of all neighboring cells of the serving cell; and the first time delay difference range is determined according to a difference between the transmission time delay between the terminal and the serving cell and the transmission time delay between the terminal and all neighboring cells.

[0117] In response to the time period configuration being a group time period configuration, the updated indication information indicating a second time delay difference range is reported according to the first transmission time delay difference, wherein the group time period configuration determines a time period of measuring SSBs that is used for all neighboring cells in a neighboring cell group of the serving cell; and the second time delay difference range is determined according to a difference between the transmission time delay between the terminal and the serving cell and the transmission time delay between the terminal and each neighboring cell in the neighboring cell group in which the SSB detection failure occurs.

[0118] In response to the time period configuration being a cell time period configuration, the updated indication information indicating the first transmission time delay difference is reported according to the first transmission time delay difference; and the cell time period configuration is used to determine a time period of measuring SSBs of one neighboring cell of the serving cell.

[0119] If the time period of measuring SSBs is determined according to the common time period configuration, the first transmission time delay difference is determined, and transmission time delay differences corresponding to all neighboring cells of the serving cell are also determined, and the range of the transmission time delay differences corresponding to all neighboring cells of the serving cell is reported in the entire updated indication information.

[0120] For example, the first transmission time delay difference is p1, and the transmission time delay of other neighboring cells is px, x is an arbitrary positive integer indicating a neighboring cell; and the updated indication information can carry max(p1, px) and min(p1, px). Exemplarily, the first time delay difference range can be indicated by max(p1, px) and min(p1, px).

[0121] If the time period of measuring SSBs is determined according to the group time period configuration, the first transmission time delay difference is determined, and transmission time delay differences corresponding to other neighboring cells in the neighboring cell group in which the SSB detection failure occurs are also determined, and the transmission time delay differences corresponding to the neighboring cells are all differences between the transmission time delay of the terminal to the serving cell and the transmission time delay of the terminal to the neighboring cells.

[0122] For example, the first transmission delay difference is p1; the transmission delay of other neighbor cells in the neighbor cell group is py, y is any positive integer indicating other neighbor cells in the neighbor cell group except the neighbor cell with the SSB detection failure; and the update indication information can carry max(p1, py) and min(p1, py). Illustratively, the second delay difference range can be indicated by max(p1, py) and min(p1, py). If the time period for currently measuring the SSB is determined according to the cell period configuration, after the first transmission delay difference is determined, the update indication information can directly carry the first transmission delay difference and the update indication information of the neighbor cell with the direct or indirect SSB detection failure.

[0123] In one embodiment, the reporting the update indication information according to the detection result of the SSB measurement comprises:

[0124] In response to the period configuration being the initial period configuration, determining, according to the detection result of the SSB, a second transmission delay difference between the terminal and the transmission of the serving cell and the neighbor cell with the SSB detection success, respectively;

[0125] Reporting the update indication information according to the second transmission delay difference.

[0126] If the time period for currently measuring the SSB of the neighbor cell by the terminal is determined according to the initial period configuration, the terminal has not established a connection with the serving cell and cannot receive the unicast neighbor cell list. At this time, the terminal can report the transmission delay difference corresponding to all the neighbor cells with the SSB detection success to the serving cell, so that the base station of the serving cell determines whether the terminal has missed detecting the SSB of one or more neighbor cells and further determines whether the time period for measuring the SSB needs to be updated.

[0127] The difference between the transmission delay between the terminal and the serving cell and the transmission delay between the terminal and the corresponding neighbor cell is determined according to the position of the terminal, the ephemeris information of the serving cell and the ephemeris information of the corresponding neighbor cell.

[0128] In one embodiment, the ephemeris information of the serving cell is used to determine the position of the serving satellite of the serving cell, and the ephemeris information of the neighbor cell is used to determine the position of the neighbor satellite of the neighbor cell.

[0129] In one embodiment, the method further comprises: receiving the ephemeris information of the serving cell and the ephemeris information of the neighbor cell sent by the serving cell.

[0130] For example, the ephemeris information can be broadcast, groupcast or unicast by the serving cell. In this way, the terminal can receive the ephemeris information of the serving cell and / or the ephemeris information of the neighbor cell on the broadcast channel, the groupcast channel or the unicast channel.

[0131] The terminal can determine the transmission delay between the terminal and the serving cell and the neighboring cell based on the distance between the location of the terminal and the location of the serving satellite of the serving cell and the transmission rate of the wireless signal. Then, the first transmission delay difference and / or the second transmission delay difference and other transmission delay differences can be obtained by calculating the difference between the transmission delay of the serving cell and the transmission delay of the neighboring cell. In an embodiment, the transmission rate of the wireless signal can be approximately equal to the speed of light.

[0132] In another embodiment, after determining the distance, the terminal can query a preset correspondence between the distance and the transmission delay to determine the transmission delay between the terminal and the serving cell and the neighboring cell.

[0133] In some embodiments, the transmission delay of the feeder link between the communication gateway (GW) and the serving cell and the transmission delay of the feeder link between the GW and the neighboring cell are automatically compensated by the serving cell before updating the time period for measuring the SSB, so that the most appropriate time period for measuring the SSB of the neighboring cell is obtained by updating.

[0134] In an embodiment, one neighboring cell corresponds to one frequency point or one carrier.

[0135] As shown in FIG. 1, the embodiments of the present disclosure provide a method for updating a time period for measuring an SSB, which is applied to a serving cell and includes the following steps: Figure 5

[0136] S210: receiving update indication information reported by a terminal based on a detection result of an SSB of a neighboring cell;

[0137] S220: updating a time period configuration of the time period for measuring the SSB according to the update indication information, wherein the time period configuration includes indication information for determining the time period for measuring the SSB.

[0138] The method for updating the time period for measuring the SSB can be applied to the serving cell, and the execution subject of S210 to S220 can be a serving satellite of the serving cell and the like.

[0139] The serving satellite includes but is not limited to a geostationary earth orbiting (GEO) satellite and / or a low earth orbiting (LEO) satellite.

[0140] The update indication information reported by the terminal is received, and the time period for measuring the SSB of the neighboring cell by the terminal is updated according to the update indication information. ​

[0141] If the base station updates the time period of measuring SSB, a new time period configuration is generated. The network side generates a new time period configuration, and can send the new time period configuration to the terminal for use by the terminal.

[0142] The network updates the time period configuration according to the update indication information reported according to the SSB detection result of the neighboring cell, which has the characteristics of dynamically and flexibly adjusting the time period of measuring SSB, and at the same time has the characteristics of small signaling overhead.

[0143] For example, in one embodiment, the update indication information is reported by the terminal when the terminal determines that the SSB detection of at least one neighboring cell fails according to the detection result of the SSB.

[0144] The information content and other related descriptions of the update indication information can be referred to the corresponding embodiments described above, which will not be repeated here.

[0145] The update indication information can carry a transmission delay difference or not carry a transmission delay difference.

[0146] Exemplarily, the S220 can include updating the time period configuration of the time period of measuring SSB based on the transmission delay difference carried by the update indication information.

[0147] The transmission delay difference carried by the update indication information herein can include at least one of the first transmission delay difference and the second transmission delay difference in the terminal side embodiment described above.

[0148] In one embodiment, the S220 can include:

[0149] Based on the update indication information carrying the first transmission delay difference, updating the time period configuration of the time period of measuring SSB of the neighboring cell corresponding to the first transmission delay difference according to the type of the time period configuration corresponding to the first transmission delay difference; the first transmission delay difference is the difference between the transmission delay between the terminal and the serving cell and the transmission delay between the terminal and each neighboring cell in the neighboring cell group where the SSB detection fails.

[0150] On the one hand, in order to reduce unnecessary updates of time period configurations, on the other hand, in order to reduce the phenomenon of large signaling overhead consumed by the time period configuration sent due to full update, in the embodiments of the present disclosure, only the time period configuration associated with the neighboring cell whose SSB detection fails is updated.

[0151] The type of the time period configuration includes at least one of the following:

[0152] The common time period configuration for all neighboring cells of the serving cell;

[0153] The group period configuration is for one neighbor cell group of the serving cell, and the neighbor cell group includes one or more neighbor cells of the serving cell.

[0154] The cell period configuration is for a single neighbor cell of the serving cell.

[0155] In an embodiment, the updating of the period configuration of the time period of the measured SSB of the neighbor cell corresponding to the first transmission latency difference according to the type of the period configuration corresponding to the first transmission latency difference comprises at least one of the following:

[0156] In response to the period configuration corresponding to the first transmission latency difference being a common period configuration, the common period configuration is updated; wherein the common period configuration is used for determining the time period of the measured SSB that is common to all neighbor cells of the serving cell.

[0157] In response to the period configuration corresponding to the first transmission latency difference being a group period configuration, the group period configuration is updated, wherein the group period configuration is used for determining the time period of the measured SSB that is common to all neighbor cells in one neighbor cell group of the serving cell.

[0158] In response to the period configuration corresponding to the first transmission latency difference being a cell period configuration, the cell period configuration is updated, wherein the cell period configuration is used for determining the time period of the measured SSB of one neighbor cell of the serving cell.

[0159] In an embodiment, the updating of the period configuration of the time period of the measured SSB according to the update indication information comprises:

[0160] According to the update indication information, a reference value is determined.

[0161] According to the preset information for adjusting the reference value and the reference value, the period configuration is updated.

[0162] Since there are various satellites providing NTN cells in the NTN system, the motion trajectories of the satellites are also different; and the speed of the terminal itself will affect the measurement of the SSB of the neighbor cell by the terminal.

[0163] Therefore, in the embodiments of the present disclosure, in order to provide the most appropriate period configuration of the time period of the measured SSB, preset information is introduced to correct the reference value determined based on the update indication information.

[0164] In an embodiment, the preset information comprises at least one of the following:

[0165] The type of the serving satellite of the serving cell;

[0166] The type of the neighbor satellite of the neighbor cell;

[0167] ephemeris information of a serving satellite of the serving cell;

[0168] ephemeris information of a neighbor satellite of the neighbor cell;

[0169] a moving speed of the terminal.

[0170] The ephemeris information of the neighbor satellite and / or the serving satellite can be used to locate the position of the neighbor satellite and the position of the serving satellite, respectively. For example, the moving speed of the terminal can be embodied by a specific speed value or by a speed level to which the moving speed of the terminal belongs.

[0171] In an embodiment, the method further comprises:

[0172] determining an initial period configuration of the time period of the measured SSB according to a default transmission delay difference range.

[0173] Exemplarily, the default transmission delay difference range is composed of one of the following:

[0174] a first minimum value and a first maximum value, wherein the first minimum value is a minimum value of a transmission delay from any position in the serving cell to the serving cell minus a transmission delay from the corresponding position to any neighbor cell, and the first maximum value is a maximum value of the transmission delay from any position in the serving cell to the serving cell minus the transmission delay from the corresponding position to any neighbor cell;

[0175] a second minimum value and a second maximum value, wherein the second minimum value is a minimum value of a transmission delay from any position in the serving cell to any neighbor cell minus a transmission delay from the corresponding position to the serving cell, and the second maximum value is a maximum value of the transmission delay from any position in the serving cell to any neighbor cell minus the transmission delay from the corresponding position to the serving cell;

[0176] a maximum transmission delay difference range reported by a terminal accessed in the serving cell;

[0177] a transmission delay difference range determined according to historical data.

[0178] Exemplarily, the coverage of the serving cell only contains two positions, position A and position B, two neighbor cells and corresponding neighbor satellites; the transmission delay from position A to the serving satellite SA is 10, the transmission delay from the terminal to the neighbor satellite NA1 is 132, and the transmission delay from the terminal to the neighbor satellite NA2 is 9; the transmission delay from position B to the serving satellite SA is 110, the transmission delay to the neighbor satellite NA1 is 22, and the transmission delay to the neighbor satellite NA2 is 10.

[0179] If the first minimum value to the first maximum value is used, the transmission delay difference range is [-122, 100], -122 is the first minimum value; 100 is the first maximum value. If the second minimum value to the second maximum value is used, the transmission delay difference range is [-100, 122], -100 is the first minimum value; 122 is the first maximum value.

[0180] In one embodiment, the service cell currently accessed by the terminal has other terminals accessing, and the other terminals also report the delay difference range determined based on the transmission delay difference to the cell. In the embodiment of the present disclosure, the initial time period configuration of the terminal accessing the service cell is determined, which can be determined according to the maximum delay difference range reported by the other terminals. In this way, the implementation is simple.

[0181] In one embodiment, the historical data can be the transmission delay difference range used by the service cell to determine the time period configuration for the current terminal according to the time period configuration used by the current terminal and / or other terminals at the historical moment.

[0182] In summary, there are various ways to confirm the default delay range, and the specific implementation is not limited to any one of the above.

[0183] In another embodiment, the method further comprises:

[0184] updating the time period configuration of the measurement SSB time period according to the update indication information, comprises:

[0185] In one embodiment, the method further comprises: issuing ephemeris information, wherein the ephemeris information comprises ephemeris information of a service satellite of the service cell and / or ephemeris information of a neighbor satellite of the neighbor cell.

[0186] The issued ephemeris information is used for the terminal to determine the first transmission delay difference and / or the second transmission delay difference.

[0187] The ephemeris information can be broadcasted, multicast or unicast.

[0188] The embodiments of the present disclosure propose an enhanced scheme of SMTC window / Measurement GAP applicable to NTN system, in which a trade-off is made between the resources occupied by SMTC window / Measurement GAP and the update frequency, so that the impact of SMTC window / Measurement GAP on data transmission and reception can be reduced by updating the configuration of UE with less RRC signaling.

[0189] The technical solutions of the embodiments of the present disclosure can be as follows:

[0190] The UE performs SSB measurement of neighboring cells according to the configuration of the received SMTC window / Measurement GAP, and when the UE finds that the SSB of a certain neighboring cell cannot be detected through the existing SMTC window / Measurement GAP configuration, the UE reports an indication that the SSB of the neighboring cell cannot be detected (the indication can include the identification (ID) of the neighboring cell, the updated transmission delay difference, and is reported to the network through an RRC message.

[0191] If the network configures a common SMTC window / Measurement GAP for all to-be-measured neighboring cells, the UE needs to update the transmission delay difference range of the serving cell and all neighboring cells;

[0192] If the network configures different SMTC windows / Measurement GAPs for each to-be-measured neighboring cell, the UE only needs to update the transmission delay difference of the serving cell and the neighboring cell that cannot detect the SSB.

[0193] If the network configures different SMTC windows / Measurement GAPs for each group of to-be-measured neighboring cells, the UE only needs to update the range of the transmission delay difference of the to-be-measured neighboring cells in the group to which the neighboring cell that cannot detect the SSB belongs.

[0194] The network configures or updates the SMTC window / Measurement GAP according to the transmission delay difference.

[0195] For example, the network configures or updates the common SMTC window / Measurement GAP according to the range of the transmission delay difference.

[0196] For example, the network configures or updates the SMTC window / Measurement GAP of the neighboring cell according to the transmission delay difference of the neighboring cell.

[0197] For example, the network configures or updates the SMTC window / Measurement GAP of the to-be-measured neighboring cell group according to the range of the transmission delay difference of the group.

[0198] Exemplarily, the network can determine the offset value, adjust or extend the configuration of the SMTC window / measurement gap according to the type of the satellite (LEO / GEO / MEO), the movement trajectory of the satellite, and the moving speed of the UE (low speed, medium speed, high speed). The offset value herein can be determined according to the predetermined information as described above. After a reference value is determined according to the transmission delay difference or the transmission delay difference range, the calibration value is corrected according to the offset value to obtain the final value of the SMTC window / measurement gap, thereby generating a new SMTC window configuration and / or measurement gap configuration. The SMTC window configuration and the measurement gap configuration herein are both one of the time period configurations as described above.

[0199] Exemplarily, the network can only update the corresponding SMTC window / measurement gap when it receives the indication that the UE cannot detect the SSB of a certain neighbor cell and the corresponding transmission delay difference update information.

[0200] The initial configuration of the SMTC window / measurement gap is configured by the network according to the maximum transmission delay difference information in the cell. The initial configuration of the SMTC window / measurement gap can correspond to the initial time period configuration as described above.

[0201] The UE reports the transmission delay difference information of the corresponding satellite based on the neighbor cell from which the SSB is first detected, and the network updates the configuration of the SMTC window / measurement gap accordingly.

[0202] Exemplarily, the UE can store a list of neighbor cells from which the SSB is detected after the SMTC window / measurement gap is updated for the first N times, to determine whether the latest SMTC window / measurement gap configuration will result in the failure to detect the SSB of the neighbor cell in the list.

[0203] Exemplarily, a counter X is defined, and if the X corresponding to a certain neighbor cell is greater than a specified number, it is determined that the UE cannot detect the SSB of the neighbor cell through the existing SMTC window / measurement gap configuration. The failure to detect the SSB herein is a specific embodiment of the SSB detection failure as described above. The specified number herein includes but is not limited to M mentioned in the foregoing embodiments.

[0204] Exemplarily, when the UE cannot detect the SSB of a certain neighbor cell in a certain SMTC / measurement gap, the X is increased by 1, and when the UE detects the SSB of a certain neighbor cell in a certain SMTC / measurement gap, the X corresponding to the neighbor cell is cleared.

[0205] Exemplarily, the UE can detect the SSB of a certain neighbor cell in a certain SMTC / measurement gap, and there is:

[0206] The SMTC / measurement gap can contain all SSB signals;

[0207] This SMTC / gap measurement gap can contain at least n SSB signals, where n is not less than 1.

[0208] For example, the UE calculates the transmission delay difference between the serving cell and the neighboring cell under test based on its own location information and the ephemeris information of the serving cell satellite and the neighboring cell satellite.

[0209] For example, the UE can obtain the satellite's position through ephemeris information, then calculate the distance between the UE and the satellite, divide this distance by the speed of light to obtain the transmission delay of the UE in the cell covered by this satellite, and use the transmission delay of the serving cell to subtract the transmission delay of the neighboring cell to obtain the transmission delay difference. This value is a real number.

[0210] The transmission delay difference between the serving cell and the neighboring cell's feeder link can be compensated at the network end. The UE only needs to calculate the transmission delay difference of the service link portion.

[0211] For example, the UE needs to obtain the ephemeris information of the serving cell and the satellites corresponding to neighboring cells:

[0212] The network directly provides the UE with ephemeris information of the serving cell and the corresponding satellites of neighboring cells;

[0213] The UE obtains the identifiers of the serving cell and neighboring cells through the network, and then obtains their ephemeris information based on its own pre-configured information.

[0214] The neighboring cell mentioned in this embodiment can be a certain frequency point or a certain cell.
