[0032] Embodiments of the present disclosure are described in detail below with reference to the accompanying drawings, examples of which are shown in the drawings, wherein the same or similar notations denote the same or similar elements throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present disclosure, and should not be understood as limiting the present disclosure.

[0033] Referring to FIG. 1, FIG. 1 is a schematic diagram of an architecture of a communication system according to an embodiment of the present disclosure. The communication system can include, but is not limited to, one satellite and one terminal. The number and form of devices shown in FIG. 1 are only examples and do not constitute a limitation on the embodiments of the present disclosure. In actual applications, two or more satellites and two or more terminals can be included. The communication system shown in FIG. 1 takes one satellite 101 and one terminal 102 as an example.

[0034] The satellite 101 in the embodiments of the present disclosure is an entity for transmitting or receiving signals. The embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the satellite.

[0035] The terminal 102 in the embodiments of the present disclosure is an entity for receiving or transmitting signals on the user side, such as a mobile phone. The terminal can also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal can be a car, smart car, mobile phone, wearable device, tablet computer (Pad), computer with wireless transceiver function, virtual reality (VR) terminal, augmented reality (AR) terminal, wireless terminal in industrial control, wireless terminal in self-driving, wireless terminal in remote medical surgery, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, etc. The embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal.

[0036] It can be understood that the communication system described in the embodiments of the present disclosure is for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Those skilled in the art can know that, with the evolution of system architecture and the appearance of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0037] The communication method provided by the present disclosure and the apparatus thereof will be described in detail below in conjunction with the accompanying drawings. FIG. 2 is a flowchart of a communication method provided by an embodiment of the present disclosure. In the embodiments of the present disclosure, the communication method can be executed by a network device, and the present disclosure is not limited in this regard.

[0038] As shown in FIG. 2, the communication method comprises the following steps.

[0039] S201: Determine the synchronization signal and physical broadcast channel block (SSB) index of the edge wave position.

[0040] Due to the wide coverage of the satellite, the embodiments of the present disclosure can additionally introduce the concept of geographical area of wave position, and one cell can cover multiple wave positions. Due to the limited width of the beam, usually one beam can only serve one wave position at one time. The satellite can cover the numerous wave positions of the entire cell by means of beam scanning.

[0041] Wherein, the edge wave position is, for example, the wave position located at the edge of the serving cell.

[0042] Wherein, the synchronization signal and physical broadcast channel block (SSB) index of the edge wave position can be used to identify the edge wave position.

[0043] Wherein, the number of edge wave positions can be one or more.

[0044] In the embodiments of the present disclosure, the SSB index of the edge wave position can be used to determine the edge wave position of the serving cell.

[0045] Optionally, in some embodiments, there is a corresponding relationship between the SSB index of the edge wave position and the edge wave position. Thus, both the terminal and the network device can accurately learn the edge wave position in the serving cell based on the SSB index of the edge wave position.

[0046] Optionally, in some embodiments, the SSB indexes of the edge wave positions are sequentially arranged along the edge of the serving cell. Thus, the determination efficiency of the edge wave position of the serving cell can be effectively improved.

[0047] That is to say, the SSB index of the edge wave position can be arranged in a certain order along the edge of the serving cell, such as arranged in ascending order (1, 2, 3, …, and so on) in the clockwise direction, or arranged in descending order (…, 3, 2, 1, and so on) in the clockwise direction, which is not limited.

[0048] In the embodiments of the present disclosure, the SSB indexes corresponding to each edge wave position of the serving cell can be arranged continuously, such as in a counterclockwise direction or in a clockwise direction. As shown in FIG. 3, FIG. 3 is a schematic diagram of continuous distribution of SSB indexes based on cell edges in the embodiments of the present disclosure. In FIG. 3, the cell edge is a simplified expression of the edge position of the serving cell. In FIG. 3, the left part is a cell containing multiple wave positions. For the edge wave position, the SSB indexes are sequentially distributed from 0 to n, and the new cell system information parameter "SSB index boundary of edge wave position (SSBIndexBoundary)" is defined as n (i.e., the maximum value of the SSB index of the edge wave position); or the SSB index distribution plan of the cell edge is defined as: starting from the maximum value (max) of the SSB index in the SSB pattern used by the cell, sequentially decreasing to n, at this time, the SSBIndexBoundary of the edge wave position is n (as shown in the right part of FIG. 3). In the embodiments of the present disclosure, the actual cell shape can be related to the specific communication implementation scheme, and the above-mentioned honeycomb hexagonal cell is only an example, and the method provided in the embodiments of the present disclosure is not limited to this, and can be applied to any shape of cell. For simplicity of description, the SSB indexes of the edge wave position are arranged in ascending order in the embodiments of the present disclosure, and this is not limited.

[0049] Optionally, in some embodiments, the SSB indexes of the edge wave position are arranged in a space division manner at the edge of the serving cell. Thus, the scenario of a large number of cell coverage wave positions can be met. That is to say, the same SSB index can appear at different geographical positions within the same cell coverage. Different edge wave positions can reuse the same SSB index. As shown in the following FIG. 4.

[0050] Optionally, in some embodiments, the SSB indexes of multiple edge wave positions can be concentrated in one subframe, and this is not limited.

[0051] In the embodiments of the present disclosure, if the number of wave positions covered by a cell is large and has exceeded the maximum SSB index (for example, the SSB index range is 0 to 63, a total of 64), a space division manner can be used for beam coverage. The SSB indexes corresponding to the edge wave position can be arranged in a space division manner at the edge of the cell, such as when 64 SSB indexes are needed to cover a regular hexagonal cell with an edge length of 7 wave positions and a total of 127 wave positions, the edge wave position can be distributed in the space division coverage manner as shown in the following FIG. 4. FIG. 4 is a schematic diagram of continuous distribution of edge wave position SSB indexes in the embodiments of the present disclosure.

[0052] Optionally, in some embodiments, the SSB indexes of adjacent edge wave positions are continuous or discontinuous. Thus, the flexibility of the method implementation can be effectively improved, and possible interference between wave positions can be avoided.

[0053] In the embodiments of the present disclosure, due to different wave position sizes of different satellite systems, different overlapping sizes between cells, and different transmission periods of system information, the definition of a cell edge can be the width of one or more wave positions, which can be flexibly formulated according to actual system needs.

[0054] In the embodiments of the present disclosure, the SSB index can be slightly adjusted in a small range to adapt to the present scheme. For example, the SSB indexes on the continuous wave positions can be adjusted from 0, 1, 2, 3 to 0, 2, 1, 3. Thus, the interference caused by the overlapping coverage of wave beams between wave positions can be avoided.

[0055] In some embodiments, the network device can send first information to the terminal to indicate the interval of the SSB index of the edge wave position, and the terminal can receive the first information sent by the network device and learn the edge wave position in the serving cell based on the first information.

[0056] In the embodiments of the present disclosure, the first information can include SSBIndexBoundary, that is, the boundary value of the SSB index mapped by the edge wave position. The terminal can be informed by adding a cell system message element. For example, SSBIndexBoundary can be added in the home star configuration of the system information block (System Information Block 19, SIB19) (or SSBIndexBoundary can be added in the system information such as SIB1). As shown in FIG. 5, FIG. 5 is a schematic diagram of adding an edge wave position indication in SIB19 in the embodiments of the present disclosure. In the example, the terminal is UE, and the network device is a base station gNB.

[0057] Thus, by adding an indication of one byte in the air interface, the SSB index range (that is, the interval) of the edge wave position can be synchronized between the network device and the terminal.

[0058] S202: According to the SSB index of the edge wave position, the neighbor cell related system information of the serving cell is broadcasted on the edge wave position.

[0059] In the embodiments of the present disclosure, the neighbor cell related system information can not be broadcasted on the non-edge wave position.

[0060] In some embodiments, the network device can determine the edge wave position from the multiple wave positions of the serving cell according to the SSB index of the edge wave position, and then the network device can broadcast the neighbor cell related system information of the serving cell only on the edge wave position, and the neighbor cell related system information is not broadcasted on the non-edge wave position.

[0061] The neighbor cell system information can be, for example, neighbor cell configuration NeighCellConfig information in SIB2, SIB3, SIB4, SIB5, and SIB19.

[0062] That is, the network device can broadcast the system based on the edge beam position, that is, the network device can broadcast the "neighbor cell related SIB" only on the beam position of the edge beam position [0, SSBIndexBoundary], and not broadcast the "neighbor cell related SIB" on the non-edge beam position. The terminal re-reads the system broadcast once when the SSB index of the serving beam changes to the edge beam position, and acquires the "neighbor cell related SIB".

[0063] As shown in FIG. 6, FIG. 6 is a scene diagram for determining the edge beam position based on the SSB index in the embodiment of the present disclosure. The network device can not broadcast the "neighbor cell related SIB" on the non-edge beam position. The terminal (such as UE0 and UE1 in FIG. 6) in this area also does not need to acquire the "neighbor cell related SIB". The network device can broadcast the "neighbor cell related SIB" on the edge beam position. The terminal (such as UE2 in FIG. 6) in this area performs system information update and acquires the "neighbor cell related SIB" if it is detected that the serving beam changes to the edge beam position [0, SSBIndexBoundary] (such as SSB index 22 in FIG. 6).

[0064] In the embodiment, the network device can determine the synchronization signal and physical broadcast channel block SSB index of the edge beam position, and broadcast the neighbor cell related system information of the serving cell on the edge beam position according to the SSB index of the edge beam position, wherein the neighbor cell related system information is not broadcast on the non-edge beam position. This can effectively save system resources and improve system resource utilization.

[0065] In some embodiments of the present disclosure, the network device can send second information to the terminal, wherein the second information indicates an interval of the SSB index of at least part of the edge beam position for measurement.

[0066] In some embodiments of the present disclosure, the interval of the SSB index of the edge beam position is the same as or different from the interval of the SSB index of at least part of the edge beam position for measurement.

[0067] In some embodiments of the present disclosure, the coverage range of the interval of the SSB index of the edge beam position can be greater than the coverage range of the interval of the SSB index of at least part of the edge beam position for measurement.

[0068] In an example, SSBIndexBoundaryforSIB can be used to express the broadcast range of the neighbor cell system information in the serving cell of the terminal. The broadcast range of the neighbor cell system information in the serving cell of the terminal and the area in which the terminal starts the neighbor cell measurement can be indicated by the same or different values. As shown in FIG. 7, FIG. 7 is a schematic diagram of the broadcast range of the neighbor cell system information and the area in which the terminal starts the neighbor cell measurement in an embodiment of the present disclosure. The area in which the terminal starts the neighbor cell measurement can be indicated by, for example, SSBIndexBoundaryforMeas. If different values are needed, the network device can configure two edge indexes in the system information, for example, add SSBIndexBoundaryforSIB and SSBIndexBoundaryforMeas in SIB19. SSBIndexBoundaryforSIB represents the broadcast range of the neighbor cell system information, which is greater than the area in which the terminal starts the neighbor cell measurement represented by SSBIndexBoundaryforMeas.

[0069] FIG. 8 is a flowchart of another communication method provided by an embodiment of the present disclosure. In the embodiment of the present disclosure, the communication method can be performed by a terminal, without limitation.

[0070] As shown in FIG. 8, the communication method includes the following steps.

[0071] S801: Determine the SSB index of the serving beam.

[0072] In some embodiments, the terminal can determine the SSB index of the serving beam. The terminal can determine whether the terminal is at the edge of the serving cell based on the SSB index of the serving beam.

[0073] S802: If the SSB index of the serving beam is the SSB index of the edge beam, receive the neighbor cell related system information of the serving cell on the edge beam.

[0074] In some embodiments, the terminal can determine whether the terminal is at the edge of the serving cell by using the SSB index of the current serving beam. When the terminal enters the coverage range of the edge beam [0, SSBIndexBoundary] (i.e., the SSB index of the current serving beam is the SSB index of the edge beam), the terminal receives the neighbor cell related system information of the serving cell on the edge beam. Then, the terminal can start the measurement on the neighbor cell of the serving cell. When the terminal is not in the edge beam (i.e., the SSB index of the current serving beam is not the SSB index of the edge beam), the terminal can not receive the neighbor cell related system information of the serving cell. The terminal can also not perform the measurement on the neighbor cell, thereby greatly reducing the resource consumption of the terminal. In addition, the power consumption required by the terminal for measurement can also be reduced.

[0075] In the embodiments of the present disclosure, if the SSB index of the serving beam is the SSB index of the edge beam position, the terminal receives the neighbor cell related system information of the serving cell on the edge beam position. That is, the terminal can acquire the neighbor cell system information when it is determined that it is at the edge of the serving cell, to support measurement on the neighbor cell of the serving cell, and can not acquire the neighbor cell system information when it is not at the edge of the serving cell, thereby effectively saving power consumption and air interface resources.

[0076] In some embodiments, the terminal can receive first information sent by the network device, wherein the first information indicates the interval of the SSB index of the edge beam position. Thus, the terminal can refer to the first information to efficiently determine whether the SSB index of the serving beam is the SSB index of the edge beam position.

[0077] In some embodiments, if the SSB index of the serving beam is in the interval of the SSB index of the edge beam position, it is indicated that the SSB index of the serving beam is the SSB index of the edge beam position, and if the SSB index of the serving beam is not in the interval of the SSB index of the edge beam position, it is indicated that the SSB index of the serving beam is not the SSB index of the edge beam position.

[0078] In some embodiments, the terminal can further receive second information sent by the network device, wherein the second information indicates the interval of the SSB index of at least part of the edge beam position for measurement.

[0079] FIG. 9 is a flow diagram of another communication method provided by the embodiments of the present disclosure. In the embodiments of the present disclosure, the communication method can be performed by a terminal, and the present disclosure does not make any limitation in this regard.

[0080] As shown in FIG. 9, the communication method includes the following steps.

[0081] S901: Determine the SSB index of the serving beam.

[0082] S902: If the SSB index of the serving beam is the SSB index of the edge beam position, receive the neighbor cell related system information of the serving cell on the edge beam position.

[0083] S903: Acquire the neighbor cell measurement window configuration in the neighbor cell related system information, wherein the neighbor cell measurement window configuration includes a measurement object and an initial measurement window.

[0084] In some embodiments, the terminal can further acquire the neighbor cell measurement window configuration in the neighbor cell system information, wherein the neighbor cell measurement window configuration includes a measurement object and an initial measurement window, and refer to the measurement object and the initial measurement window to perform measurement on the neighbor cell of the serving cell.

[0085] S904: Measure at least one candidate beam of the neighbor cell in the initial measurement window based on the measurement value of the measurement object.

[0086] In some embodiments, the terminal can measure one or more candidate beams in the neighbor cell in the initial measurement window, and trigger the next measurement of the neighbor cell of the serving cell based on the measurement value of the measurement object.

[0087] S905: Obtain the SSB index of the candidate beam to which the maximum measurement value in the plurality of measurement values belongs.

[0088] S906: Determine the first measurement window used for the next measurement of the neighbor cell according to the SSB index of the candidate beam to which the maximum measurement value belongs and the SSB index of at least part of the edge beam positions used for measurement.

[0089] In some embodiments, in the process of determining the first measurement window according to the SSB index of the candidate beam to which the maximum measurement value belongs and the SSB index of at least part of the edge beam positions used for measurement, if the SSB index of the candidate beam to which the maximum measurement value belongs is the SSB index of at least part of the edge beam positions used for measurement, the first measurement window is determined according to the SSB index of the candidate beam to which the maximum measurement value belongs; if the SSB index of the candidate beam to which the maximum measurement value belongs is not the SSB index of at least part of the edge beam positions used for measurement, the initial measurement window is taken as the first measurement window. Thus, the size of the measurement window can be automatically adjusted when measuring the neighbor cell of the serving cell.

[0090] Optionally, in some embodiments, in the process of determining the first measurement window according to the SSB index of the candidate beam to which the maximum measurement value belongs, the range between the first time domain position corresponding to the SSB index of the candidate beam to which the maximum measurement value belongs and the second time domain position corresponding to the SSB index of the candidate beam to which the maximum measurement value belongs can be taken as the first measurement window; wherein the first time domain position is the time domain position corresponding to the first index obtained by subtracting a preset value from the SSB index of the candidate beam to which the maximum measurement value belongs, and the second time domain position is the time domain position corresponding to the second index obtained by adding the preset value to the SSB index of the candidate beam to which the maximum measurement value belongs. Thus, by further shortening the measurement window, the terminal power consumption and the impact of measurement on the transmission of service data can be further reduced.

[0091] For example, the preset value is 1 or 2.

[0092] For example, the preset value is 1 or 2.

[0092]

[0093] As shown in FIG. 10, FIG. 10 is a schematic diagram of a measurement window in an embodiment of the present disclosure. Taking SSB pattern case E with a subcarrier spacing (SCS) of 240 kHz as an example, when the cell coverage is a regular hexagon with a side length of 5 wave positions, the SSB indexes corresponding to the edge wave positions can be concentrated in sbi0-sbi23 (where sbi0 and sbi23 are an optional example of SSB indexes) in an embodiment of the present disclosure. Since the edge SSB indexes of the neighboring cells are concentrated in one subframe, the configuration of the measurement time window can be reduced from 2 ms to less than 1 ms from the perspective of network configuration in an embodiment of the present disclosure. By shortening the measurement window, the terminal power consumption consumed by the neighboring cell measurement can be reduced, and the impact of the neighboring cell measurement on the service rate can be effectively reduced.

[0094] In a satellite communication system, the motion trajectory and coverage area of a satellite can be expected. When the network device obtains the position of the terminal, or the neighboring cell system information is broadcast at the wave position level, the neighboring cell of the position of the terminal can be uniquely determined. Therefore, in an embodiment of the present disclosure, the network device can configure a single neighboring cell for the terminal. When the network device configures a single neighboring cell, the terminal can further shorten the measurement window automatically.

[0095] As shown in FIG. 11, FIG. 11 is a schematic diagram of the terminal shortening the measurement window in an embodiment of the present disclosure. The terminal first performs neighboring cell measurement according to the measurement window configured by the network (an optional example of the initial measurement window). When the strongest beam of the neighboring cell (an optional example of the candidate beam with the maximum measurement value) is detected, the measurement window can be further shortened in subsequent measurement. If the measurement window can cover the i SSB indexes (i=1 or 2, an optional example of a preset value) before and after the strongest beam, the mobility requirement can be met. Because the adjacent SSB indexes in the time domain are also adjacent wave positions in the space domain. Since the wave position of the satellite is large, the terminal usually does not appear to cross the wave position within the two measurement intervals (if these conditions are not met, the size of i can be appropriately increased). When the terminal and the cell have relative position changes, the strongest beam of the neighboring cell changes, and the measurement window also moves automatically, and can automatically cover the new adjacent wave position.

[0096] As shown in FIG. 12, FIG. 12 is a schematic diagram of automatic adjustment of a measurement window by a terminal in an embodiment of the present disclosure. At time T1, the terminal is in a wave position covered by SSB index 22, and the terminal measures the strongest beam of a neighboring cell to be SSB index 8 within the 1 ms measurement window configured by the network. After detecting the strongest beam of the neighboring cell, the terminal can further reduce the measurement window to 1 to 2 SSB indexes before and after the time domain position of SSB index 8, for example, as shown in FIG. 12, the measurement window can be reduced to SSB indexes 7 to 9. Then, if the relative position of the terminal and the cell does not change, the measurement window can remain unchanged at the shortened length. At time T2, the terminal moves to a wave position covered by SSB index 21, and the strongest beam of the neighboring cell becomes index 9. This beam is also in the measurement window at T1 (indexes 7 to 9), and will not be missed due to the reduction of the measurement window. Because the strongest beam of the neighboring cell changes, the terminal automatically slides the measurement window by one SSB index, that is, adjusts the measurement window to be SSB indexes 8 to 10. In this way, the measurement window can always be minimized, and can also frame the adjacent beams of the neighboring cell.

[0097] As shown in FIG. 13, FIG. 13 is a schematic diagram of the effect of reduction of the measurement window by the terminal in an embodiment of the present disclosure.

[0098] In an embodiment of the present disclosure, after the terminal detects the strongest SSB of the neighboring cell within the measurement window, if the terminal is configured with only a single neighboring cell, the terminal can further shorten the measurement window: the terminal takes the time domain position of the strongest beam (for example, SSB index N) measured by the terminal once before as the center, and shortens the measurement window to SSB index N-i to SSB index N+i (i=1 or 2). In order to reduce the power consumption caused by measurement.

[0099] In this embodiment, the SSB index of the beam is combined with the beam position, the SSB index is arranged in ascending or descending order along the edge position of the serving cell, and the boundary value of the SSB index of the edge beam position is indicated to the terminal through the system message. By extending the system message by one byte, the terminal can determine whether it is at the edge position of the serving cell based on the SSB index. Not affected by the low near-far effect in satellite communication, and not dependent on the shape of the cell, the cell can be efficiently divided into edge beam positions and non-edge beam positions. For non-edge beam positions, the network does not broadcast system information related to neighboring cells, and the terminal identifies the entry into the edge position of the serving cell through the SSB index and updates the system broadcast information, thereby reducing the network power consumption. On the one hand, after the terminal identifies the edge beam position, it determines whether to start the neighboring cell measurement process based on whether the terminal is at the edge position of the serving cell, thereby more accurately starting or stopping the neighboring cell measurement. On the other hand, when the terminal is at the edge position of the serving cell, since the edge beam positions of the neighboring cells are arranged continuously according to the SSB index, the SSB indexes of the edge beam positions are concentrated in the time domain. Therefore, the measurement window configured by the network device is automatically reduced. The reduction of the measurement window can reduce the terminal power consumption and save channel resources to improve the business transmission rate. Since the SSB indexes of the edge beam positions of the neighboring cells are continuous, when a single neighboring cell is configured, after the terminal detects the neighboring cell beam based on the measurement window configured by the network, the time domain position of the strongest beam can be taken as the center, and the time domain width of 1 to 2 SSB indexes covered by each other is expanded forward and backward, and the subsequent measurement is performed based on the measurement window. The measurement window is further shortened, and the system resources are further saved and the terminal power consumption is further reduced.

[0100] It should be noted that in the following embodiments, the description of the same or corresponding terms and method steps as in the above embodiments can be specifically referred to the above embodiments, and will not be described here.

[0101] The above embodiments are illustrated as follows:

[0102] As shown in FIG. 14, FIG. 14 is an application scenario diagram in the embodiment of the present disclosure. It is assumed that the subcarrier spacing SCS of the SSB pattern is 240 kHz, and the SSB index can be taken in the range of 0 to 63. It is assumed that the cell topology structure is a regular hexagon with a side length of 5 beam positions, and the entire cell contains 61 beam positions, of which 24 are edge beam positions.

[0103] Step 0, the network informs the terminal that the SSB index corresponding to the edge beam position is 0-23 through the newly added indication element SSBIndexBoundary(23) in sib19.

[0104] Step 1, the network does not send the neighbor related SIB (sib2~sib5, and the neighbor star configuration in sib19) on the non-edge beam position. The terminal determines that it is currently in the edge position of the serving cell through the SSB index of the serving beam. The terminal does not need to receive the neighbor related system information, and does not need to measure the signal strength of the neighbor.

[0105] Step 2, due to satellite movement or terminal movement, the terminal changes the serving beam to SSB index 22. The terminal determines that it is currently in the edge position of the serving cell through the SSB index of the serving beam. The terminal renews the system information and starts the neighbor measurement. The network sends the neighbor related system information. And configure the duration of SSB Measurement Timing Configuration (SMTC) as 1ms, and the Measurement Gap Length (MGL) as 1.5ms.

[0106] Step 2.1, if the network only configures one neighbor based on the position of the beam, the terminal detects that the strongest SSB index of the neighbor in the SMTC window is 8. Thereafter, the terminal can adjust the measurement window to the time domain position of SSB index 7~9 by itself.

[0107] Step 3, due to satellite movement or terminal movement, the terminal changes the serving beam to SSB index 21. The strongest beam of the neighbor becomes SSB index 9, which still belongs to the measurement window of step 2.1. The terminal changes the measurement window to the time domain position of SSB index 8~10 based on SSB index 9. The measurement window is kept minimum, and the beam position of the neighbor that needs to be measured is not missed.
