[0033] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0034] The integration of NTN and terrestrial cellular communication networks can provide robust coverage, forming a ubiquitous access network that integrates air, space, land, and sea. Currently, most satellite communication systems use multi-beam antennas. However, due to the large service range of satellites and limited beam coverage, the satellite's coverage area must be divided into several beams, using time division multiplexing to ensure coverage for users in every area. However, due to differences in geographical environment, population density, and service types, the number of users and traffic volume in different beams can vary. Static beam scheduling, which fixes the beam direction for each time slot, can easily waste time resources. Furthermore, since user terminals must wait until the same beam is scheduled before transmitting or receiving information, setting the beam repetition interval too long will increase the scheduling latency of the user terminal. However, if the beam repetition interval is too short, due to the greater transmission latency of satellite communication compared to terrestrial cellular communication, the user terminal may miss the scheduled moment for its beam, resulting in a waste of time resources.

[0035] The wave position scheduling method provided in this application can be applied to Figure 1 In the application environment shown, terminal 102 communicates with satellite base station 104. Terminal 102 can be, but is not limited to, various desktop computers, laptops, smartphones, tablet computers, vehicle-mounted terminals, intelligent voice interaction devices, aircraft, smart home appliances, and portable wearable devices. Smart home appliances can include smart speakers, smart TVs, and smart air conditioners. Portable wearable devices can include smart watches, smart bracelets, and head-mounted devices.

[0036] Specifically, satellite base station 104 performs waveband grouping planning based on the maximum number of synchronization signal blocks sent by the satellite base station and the cell-level round-trip transmission delay to determine the waveband grouping information for each public message. Based on the actual number of synchronization signal blocks sent by the satellite base station and the waveband grouping information, satellite base station 104 determines the time slot type identifier and the corresponding waveband affiliation identifier for each time slot to generate a semi-static waveband scheduling pattern. Waveband-level time-domain scheduling is performed based on the semi-static waveband scheduling pattern to obtain a waveband scheduling result for each time slot. For each time slot, based on the waveband scheduling result for that time slot, satellite base station 104 determines the waveband indicated by the waveband affiliation identifier for scheduling that time slot. Then, terminal 102-level time-domain scheduling is performed for each terminal 102 in the waveband user queue for that determined waveband.

[0037] It is understood that this embodiment does not limit this. Figure 1 The application scenarios are only for illustration and are not limited to this.

[0038] In one embodiment, Figure 2 As shown, a system message configuration method is provided, which is applied to a satellite base station and includes the following steps:

[0039] Step 202: Obtain the window offset and sending period of the system message.

[0040] In one embodiment, the system message may be an OSI (Other System Information) message. The satellite base station may obtain a SI-SchedulingInfo information element, wherein the SI-SchedulingInfo information element includes a window offset of an SI window of the OSI message.

[0041] Step 204: Configure the starting position of the system message according to the window offset and the sending period.

[0042] In one embodiment, the starting position of the system message includes the system frame number SFN and the time slot number a, which satisfies the following formula:

[0043] (SFN-Offset)%T=FLOOR(x / N);

[0044] a=x mod N;

[0045] Where: Offset is the window offset, T is the transmission period, x is an integer value, N is the number of time slots corresponding to a radio frame, FLOOR() is the floor operation, and mod is the remainder operation.

[0046] In one embodiment, the integer value satisfies the following formula:

[0047] x=(n-1)×w

[0048] Where: n is the target number of the system message, and w is the window length of the system message.

[0049] The above-mentioned system message configuration method obtains the window offset and sending period of the system message; configures the starting position of the system message according to the window offset and sending period, and can flexibly configure the system message in the non-terrestrial network, thereby improving the communication efficiency of the non-terrestrial network.

[0050] In one embodiment, Figure 3 As shown, a beam position scheduling method is provided, which is applied to a satellite base station. The beam coverage range of the satellite base station is divided into multiple beam positions, including the following steps:

[0051] Step 302: Acquire the waveband grouping information of the public message, where the public message includes the system message. The waveband grouping information includes the starting position of the public message, where the starting position of the system message is determined by the aforementioned configuration method.

[0052] A public message is a control message or information broadcast from a satellite base station to all user terminals. Wavelength grouping information is information about a wavelength group containing multiple wavelengths. A wavelength group is obtained by grouping the wavelengths within the satellite base station's beam coverage area.

[0053] Specifically, the satellite base station can obtain the waveband grouping information of public messages, which include system messages. The waveband grouping information includes the starting position of the system message determined by the system message configuration method. In other words, the satellite base station can obtain the window offset and transmission period of the system message. Based on the window offset and transmission period, the starting position of the system message is configured.

[0054] Step 304: Determine the time slot type identifier and the corresponding waveband belonging identifier of each time slot according to the waveband grouping information to generate a semi-static waveband scheduling pattern.

[0055] The slot type identifier is used to identify the slot type to which the slot belongs. Slot types include static and dynamic slot types. The static slot type identifier identifies a static slot, while the dynamic slot type identifier identifies a dynamic slot. The beam position identifier identifies a beam position. Each slot in the semi-static beam position scheduling pattern is identified as either a static slot or a dynamic slot.

[0056] Step 306: Perform wave-level time-domain scheduling and terminal-level time-domain scheduling based on the semi-static wave-level scheduling pattern.

[0057] Specifically, since each time slot in the semi-static wave scheduling pattern is identified as a static time slot and a dynamic time slot, the satellite base station can perform wave level time domain scheduling and terminal level time domain scheduling based on the static time slots and dynamic time slots identified in the semi-static wave scheduling pattern to obtain the wave scheduling results of each time slot.

[0058] In the above-mentioned waveband scheduling method, the waveband grouping information of the public message is obtained through the satellite base station. The public message includes the system message, and the waveband grouping information includes the starting position of the system message. Based on the waveband grouping information, the time slot type identifier and the corresponding waveband attribution identifier of each time slot are determined to generate a semi-static waveband scheduling pattern. Waveband-level time domain scheduling and terminal-level time domain scheduling are performed based on the semi-static waveband scheduling pattern. Compared with the traditional waveband scheduling method, the present application generates a semi-static waveband scheduling pattern, performs waveband-level time domain scheduling based on the semi-static waveband scheduling pattern, and performs terminal-level time domain scheduling for each terminal connected to the corresponding waveband based on the waveband scheduling results of each time slot. Therefore, in the waveband scheduling process of the non-terrestrial network, it is possible to avoid the waste of time domain resources and reduce the scheduling delay of the terminal.

[0059] In one embodiment, the wave bit grouping information also includes the wave bit group capacity and wave bit group interval of the public message; obtaining the wave bit grouping information of the public message includes: performing wave bit grouping planning based on the maximum number of synchronization signal blocks sent by the satellite base station and the cell-level round-trip transmission delay, and determining the wave bit group capacity, wave bit group interval and starting position of the public message; wherein, the wave bit group capacity of each wave bit group obtained by dividing the same public message is the same, and the sum of the wave bit group capacities of each wave bit group obtained by dividing the same public message is equal to the maximum number of synchronization signal blocks sent; the wave bit repetition time interval is greater than the cell-level round-trip transmission delay; the wave bit repetition time interval is the time slot interval corresponding to the starting positions of different public messages.

[0060] The Synchronization Signal Block (SSB) is a signal block used in satellite communication systems to achieve synchronization and timing between the user terminal and the satellite base station. The maximum number of SSBs sent is the maximum number of SSBs a satellite base station can send. The cell-level round-trip transmission delay is the round-trip transmission delay between the satellite base station and the user terminal.

[0061] Specifically, the maximum number of synchronization signal blocks sent is the same as the number of wave positions into which the beam coverage range of the satellite base station is divided, and one synchronization signal block corresponds to one wave position. Figure 4 As shown, the satellite base station can perform wave bit grouping planning based on the maximum number of synchronization signal blocks sent by the satellite base station and the cell-level round-trip transmission delay to determine the wave bit group capacity N, wave bit group interval T and starting position of each public message. Among them, the wave bit group capacity N of each wave bit group obtained by dividing for the same public message is the same, and the sum of the wave bit group capacity N of each wave bit group obtained by dividing for the same public message is equal to the maximum number of synchronization signal blocks sent. For example, if the maximum number of synchronization signal blocks sent is 128, then the 128 wave bits into which the beam coverage range of the satellite base station is divided can be divided into 32 wave bits with a wave bit group capacity N of 4. The wave bit repetition time interval is greater than the cell-level round-trip transmission delay. The wave bit repetition time interval is the time slot interval corresponding to the starting positions of different public messages within the same wave bit scheduling pattern period.

[0062] As you can understand, due to the large satellite service range, the number of allocated wavebands is large. To ensure service for all terminals on different wavebands, the satellite base station must broadcast all public messages once for each waveband. If each public message were to be scheduled sequentially across all wavebands, the waveband repetition interval would be too long, increasing terminal scheduling latency. Therefore, the present invention designs a satellite base station to group and schedule the wavebands for each public message, taking into account the maximum number of synchronization signal blocks sent and the cell-level round-trip transmission delay. This defines the waveband grouping information for each public message, namely, the waveband group capacity, waveband group interval, and starting position. The waveband group capacity and waveband group interval for different public messages can be the same or different. This allows the satellite base station to schedule wavebands according to the waveband group interval, scheduling wavebands within a waveband group sequentially while interleaving other types of public messages between wavebands. Terminals can be rescheduled without waiting for all wavebands to be traversed, reducing terminal scheduling latency.

[0063] In one embodiment, the common message further includes at least one of a SIB1 message or a Paging message.

[0064] In one embodiment, after the wave group capacity, wave group interval and starting position of each public message are determined, the satellite base station can broadcast the corresponding public message parameter configuration to the terminal. Public messages can be divided into three categories: System Information Block 1 (SIB1), Other System Information (OSI), and Paging messages. Among them, the wave group capacity and wave group interval of each public message can be indicated to the terminal by configuring the corresponding parameters in the corresponding PDCCH search space. The starting position of the SIB1 message and the Paging message can be indicated at any position by configuring the corresponding parameters in the PDCCH-ConfigSIB1 element and the PCCH-Conifg element. However, traditional protocol parameters do not support flexible configuration of the starting position of the OSI message, such as Figure 5 As shown, according to the traditional protocol, the starting position of the system information (SI) window of the OSI message can only be in time slot (SLOT) 0 of system frame number (SFN) 0. Therefore, this application designs a new system information window offset (si-WindowOffset) in the SI-SchedulingInfo information element to indicate the system frame offset of the SI window, so that the OSI message can be broadcast from any starting position. The calculation formula for the starting position of the OSI message is updated as follows:

[0065] The starting frame of the SI window satisfies (SFN-Offset)%T=FLOOR(x / N).

[0066] The starting time slot #a of the SI window satisfies a=x mod N.

[0067]

[0068]

[0069] In the above embodiment, the satellite base station uses the maximum number of synchronization signal blocks to be transmitted and the cell-level round-trip transmission delay to perform beamforming grouping planning, resulting in multiple beamforming groups. The satellite base station schedules the beamforming groups according to the beamforming group interval. The beamforming groups within the beamforming groups are scheduled sequentially, while other types of public messages can be scheduled between beamforming groups. This allows terminals to be rescheduled without having to wait for all beamforming groups to be traversed, thereby reducing terminal scheduling latency.

[0070] In one embodiment, based on the wave grouping information, the time slot type identifier and the corresponding wave position affiliation identifier of each time slot are determined to generate a semi-static wave position scheduling pattern, including: based on the actual number of synchronization signal blocks sent by the satellite base station and the wave grouping information, the time slot type identifier and the corresponding wave position affiliation identifier of each time slot are determined to generate a semi-static wave position scheduling pattern.

[0071] The number of synchronization signal blocks actually sent is the number of synchronization signal blocks actually sent by the satellite base station. It is understood that although the satellite base station sets a maximum number of synchronization signal blocks to be sent, the satellite base station may actually only send a portion of the synchronization signal blocks to the terminal.

[0072] Specifically, the satellite base station can determine the actual transmission of the synchronization signal, and determine the time slot type identifier and corresponding wave position attribution identifier of each time slot based on the actual number of synchronization signal blocks sent by the satellite base station and the wave position grouping information to generate a semi-static wave position scheduling pattern.

[0073] In one embodiment, according to the actual number of synchronization signal blocks sent by the satellite base station and the wave position grouping information, the time slot type identifier and the corresponding wave position attribution identifier of each time slot are determined to generate a semi-static wave position scheduling pattern, including: generating a synchronization signal block index set according to the actual number of synchronization signal blocks sent by the satellite base station; for each synchronization signal block index in the synchronization signal block index set, mapping the synchronization signal block index to the position index of the synchronization signal block index in the synchronization signal block index set to obtain index mapping information; the synchronization signal block index is the index of the synchronization signal block; according to the index mapping information and the wave position The grouping information is used to determine the time slot position corresponding to the common message of the wave position corresponding to each synchronization signal block; for each time slot position, the time slot type identifier of the time slot indicated by the time slot position is configured as a static time slot type identifier representing a static time slot, and the wave position attribution identifier of the wave position indicated by the time slot position is configured as the synchronization signal block index indicated by the corresponding index mapping information; the complement of the static time slot is taken for all time slots in the wave position scheduling pattern period to obtain a dynamic time slot set, and the time slot type identifier of the time slot included in the dynamic time slot set is configured as a dynamic time slot type identifier representing a dynamic time slot to generate a semi-static wave position scheduling pattern.

[0074] Specifically, the satellite base station may generate a synchronization signal block index set based on the number of synchronization signal blocks actually sent by the satellite base station. It is understood that the synchronization signal block index set includes the synchronization signal block index of each synchronization signal block actually sent by the satellite base station. That is, the number of synchronization signal block indexes in the synchronization signal block index set is consistent with the number of synchronization signal blocks actually sent. For each synchronization signal block index in the synchronization signal block index set, the satellite base station may map the targeted synchronization signal block index with the position index of the targeted synchronization signal block index in the synchronization signal block index set to obtain index mapping information. The synchronization signal block index is the index of the synchronization signal block. It is understood that each index mapping information includes a synchronization signal block index and its mapped position index. The satellite base station may calculate the time slot position corresponding to the common message of the corresponding wave position of each synchronization signal block based on the index mapping information and the wave position grouping information. For each time slot position, the time slot type identifier of the time slot indicated by the time slot position is configured as a static time slot type identifier representing a static time slot, and the wave position attribution identifier of the wave position indicated by the time slot position is configured as the synchronization signal block index indicated by the corresponding index mapping information. The satellite base station can take the complement of the static time slot for all time slots within the wave position scheduling pattern period to obtain a dynamic time slot set, and configure the time slot type identifiers of the time slots included in the dynamic time slot set as dynamic time slot type identifiers representing dynamic time slots to generate a semi-static wave position scheduling pattern.

[0075] In one embodiment, the starting position includes the system frame number and the time slot number, and the time slot position includes the system frame number and the time slot number. It can be understood that each system frame includes multiple time slots. The system frame number and the time slot number included in the time slot position can be calculated using the following formula:

[0076]

[0077] SLOT k =SLot first +s mod N.

[0078] Among them, SFN first Is the system frame number of the starting position of the public message, Slot first is the time slot number of the starting position of the public message, N is the wave group capacity, T is the wave group interval, k is the synchronization signal block index, s is the position index with a mapping relationship with k, mod represents the modulo operation, SFN k Is the system frame number in the time slot position, SLOT k is the slot number in the slot position.

[0079] For example, Figure 6As shown in part (a), the maximum number of SSBs sent is 16, the satellite base station configured with a wave group capacity N is 8, and the wave group interval T is one system frame. pattern =T*L max / N=2, i.e., two system frames. If the SSB is fully transmitted, for each determined time slot position, the satellite base station may configure the time slot type identifier of the time slot indicated by the time slot position as a static time slot type identifier representing a static time slot (i.e., time slot type is s), and configure the wave position attribution identifier of the wave position indicated by the time slot position as the synchronization signal block index indicated by the corresponding index mapping information (i.e., SSB indexes 0-15). Furthermore, the satellite base station may take the complement of the static time slot for all time slots within the wave position scheduling pattern period to obtain a dynamic time slot set, and configure the time slot type identifiers of the time slots included in the dynamic time slot set as dynamic time slot type identifiers representing dynamic time slots (i.e., time slot type is d), to generate a semi-static wave position scheduling pattern. Specifically, public message 1 occupies 8 consecutive time slots every other system frame starting from Slot 4 of SFN0, corresponding to the wave positions corresponding to SSB indexes 0-15, in sequence. Common Message 2 occupies eight consecutive time slots every system frame, starting from Slot 12 of SFN 1, corresponding to the SSB indices 0 through 15. After determining the static time slots for each SSB scheduling pattern period, the remaining Slots 0 through 3 of each odd-numbered system frame become dynamic time slots.

[0080] like Figure 6As shown in part (b) of the figure, the maximum number of SSBs transmitted is 16, the satellite base station configures the beam group capacity N to be 8, and the beam group interval T to be one system frame. If SSBs are partially transmitted, for each determined time slot position, the satellite base station may configure the time slot type identifier of the time slot indicated by the time slot position as a static time slot type identifier representing a static time slot (i.e., time slot type is s), and configure the beam attribution identifier of the beam indicated by the time slot position as the synchronization signal block index indicated by the corresponding index mapping information (i.e., SSB indexes 0, 1, 2, 3, 8, 9, 10, 11). Furthermore, the satellite base station may take the complement of the static time slots for all time slots within the beam scheduling pattern period to obtain a dynamic time slot set, and configure the time slot type identifiers of the time slots included in the dynamic time slot set as dynamic time slot type identifiers representing dynamic time slots (i.e., time slot type is d), thereby generating a semi-static beam scheduling pattern. Specifically, public message 1 occupies eight consecutive time slots starting from slot 4 of SFN0, corresponding to the wave positions corresponding to SSB indices 0, 1, 2, 3, 8, 9, 10, and 11, respectively. The eight static time slots originally occupied by the full SSB transmission starting from slot 4 of SFN1 can be converted to dynamic time slots. Public message 2 occupies eight consecutive time slots starting from slot 12 of SFN1, corresponding to the wave positions corresponding to SSB indices 0, 1, 2, 3, 8, 9, 10, and 11, respectively. The eight static time slots originally occupied by the full SSB transmission starting from slot 12 of SFN0 can be converted to dynamic time slots.

[0081] In the above embodiment, a synchronization signal block index set is generated based on the number of synchronization signal blocks actually transmitted by the satellite base station. For each synchronization signal block index in the synchronization signal block index set, the synchronization signal block index is mapped to its position index in the synchronization signal block index set to obtain index mapping information. Based on the index mapping information and the waveband grouping information, the time slot position corresponding to the common message of each waveband corresponding to each synchronization signal block is determined. For each time slot position, the time slot type identifier of the time slot indicated by the time slot position is configured as a static time slot type identifier representing a static time slot, and the waveband attribution identifier of the waveband indicated by the time slot position is configured as the synchronization signal block index indicated by the corresponding index mapping information. The complement of the static time slot is taken for all time slots within the waveband scheduling pattern period to obtain a dynamic time slot set, and the time slot type identifiers of the time slots included in the dynamic time slot set are configured as dynamic time slot type identifiers representing dynamic time slots to generate a semi-static waveband scheduling pattern, which can improve the efficiency and accuracy of generating the semi-static waveband scheduling pattern.

[0082] In one embodiment, waveband-level time domain scheduling includes: for each time slot in a semi-static waveband scheduling pattern, when the time slot is a static time slot, determining the waveband indicated by the waveband attribution identifier corresponding to the time slot as the scheduling waveband of the time slot, and obtaining the waveband scheduling result of the time slot; when the time slot is a dynamic time slot, determining the waveband with the highest scheduling priority in the current list of wavebands to be scheduled as the scheduling waveband of the time slot.

[0083] It can be understood that since each time slot in the semi-static waveband scheduling pattern is identified as a static time slot and a dynamic time slot, the satellite base station can perform waveband-level time domain scheduling based on the static time slots and dynamic time slots identified in the semi-static waveband scheduling pattern to obtain the waveband scheduling results for each time slot. Specifically, for each time slot in the semi-static waveband scheduling pattern, when the time slot is a static time slot, the satellite base station can determine the waveband indicated by the waveband affiliation identifier corresponding to the time slot as the scheduled waveband for the time slot, and obtain the waveband scheduling result for the time slot. When the time slot is a dynamic time slot, the satellite base station can obtain a list of wavebands to be scheduled, where each waveband in the list has a corresponding call priority. Furthermore, the satellite base station can determine the waveband with the highest scheduling priority in the list of wavebands to be scheduled as the scheduled waveband for the time slot.

[0084] In one embodiment, the base station prioritizes all the wavebands to be scheduled in the waveband list, and the sorting conditions can be a single condition or a weighted combination of multiple conditions such as the waveband waiting time, message type, waveband user capacity, and waveband traffic volume.

[0085] For example, using message type for priority sorting, the sorting criteria are: (1) the wave position of the terminal containing the msg4 message to be sent; (2) the wave position of the terminal containing other downlink messages to be sent; (3) the wave position of the terminal without downlink messages to be sent but containing uplink messages to be sent. Among them, downlink refers to the transmission direction from the satellite base station to the terminal. Uplink refers to the transmission direction from the terminal to the satellite base station. The msg4 message to be sent is the fourth message exchanged between the terminal and the satellite base station during the random access process.

[0086] In the above embodiment, for each time slot in the semi-static beam scheduling pattern, if the time slot is a static time slot, the beam indicated by the beam affiliation identifier corresponding to the time slot is directly determined as the scheduled beam for the time slot, thereby obtaining the beam scheduling result for the time slot. If the time slot is a dynamic time slot, the beam with the highest scheduling priority in the current list of beams to be scheduled is directly determined as the scheduled beam for the time slot. This improves the efficiency of determining the scheduled beam for each time slot.

[0087] In one embodiment, terminal-level time domain scheduling includes: for each time slot, based on the wave position scheduling result of the time slot, determining the wave position indicated by the wave position attribution identifier scheduled for the time slot, and performing terminal-level time domain scheduling on each terminal in the wave position user queue under the determined wave position.

[0088] The slot scheduling result for a time slot records the slot identifiers for all time slots. Because the slot identifiers can be used to identify the corresponding slot, the satellite base station can determine the corresponding slot based on the slot identifiers recorded in the slot scheduling result. The slot user queue for a slot contains the terminal of at least one user accessing that slot.

[0089] Specifically, for each time slot, the satellite base station may determine the waveband indicated by the recorded waveband attribution identifier recorded in the waveband scheduling result for the time slot. Furthermore, the satellite base station may perform terminal-level time domain scheduling for each terminal in the waveband user queue under the determined waveband.

[0090] In one embodiment, the terminal-level time domain scheduling also includes: sorting the various wave positions corresponding to the wave position user queue according to priority according to at least one of the wave position waiting scheduling time, message type, wave position user capacity or wave position business volume, and obtaining a sorted list of current wave positions to be scheduled.

[0091] In one embodiment, a time slot includes a downlink time slot and a corresponding uplink time slot, and a wave position scheduling result is an uplink and downlink wave position scheduling result; for each time slot in a semi-static wave position scheduling pattern, when the time slot is a static time slot, the wave position indicated by the wave position attribution identifier corresponding to the time slot is determined as the scheduling wave position of the time slot, and the wave position scheduling result of the time slot is obtained, including: for each time slot in the semi-static wave position scheduling pattern, when the downlink time slot of the time slot is a static time slot, the wave position indicated by the wave position attribution identifier corresponding to the downlink time slot is determined as the scheduling wave position of the downlink time slot; the uplink and downlink scheduling time slot interval is determined according to the cell-level round-trip transmission delay of the satellite base station and the scheduling timing value range of the satellite base station; the time slot position of the uplink time slot corresponding to the downlink time slot is determined according to the uplink and downlink scheduling time slot interval; the scheduling wave position of the downlink time slot is determined as the scheduling wave position of the uplink time slot, and the uplink and downlink wave position scheduling result of the time slot is obtained.

[0092] It can be understood that since each time slot in the semi-static beam scheduling pattern is identified as a static time slot and a dynamic time slot, the satellite base station can perform beam-level time-domain scheduling based on the static time slots and dynamic time slots identified in the semi-static beam scheduling pattern to obtain beam scheduling results for each time slot. Specifically, for each time slot in the semi-static beam scheduling pattern, when the downlink time slot of the time slot is a static time slot, the satellite base station can determine the beam indicated by the beam affiliation identifier corresponding to the downlink time slot as the scheduled beam for the downlink time slot. The satellite base station can determine the uplink and downlink scheduling time slot interval based on the cell-level round-trip transmission delay and the satellite base station's scheduling timing value range, and determine the time slot position of the uplink time slot corresponding to the downlink time slot based on the uplink and downlink scheduling time slot interval. Furthermore, the satellite base station can determine the scheduled beam of the downlink time slot as the scheduled beam of the uplink time slot, obtaining the uplink and downlink beam scheduling results for the time slot.

[0093] In one embodiment, for each time slot in a semi-static beam position scheduling pattern, if the downlink time slot in the targeted time slot is a static time slot, the satellite base station may determine the beam position indicated by the beam position attribution identifier corresponding to the downlink time slot as the scheduled beam position for the downlink time slot. The satellite base station may determine the uplink and downlink scheduling time slot interval based on the cell-level round-trip transmission delay and the satellite base station's scheduling timing value range, and determine the time slot position of the uplink time slot corresponding to the downlink time slot based on the uplink and downlink scheduling time slot interval. Furthermore, the satellite base station may determine the scheduled beam position of the downlink time slot as the scheduled beam position of the uplink time slot, thereby obtaining the uplink and downlink beam position scheduling result for the targeted time slot. If the downlink time slot in the targeted time slot is a dynamic time slot, the beam position with the highest scheduling priority in the current list of beam positions to be scheduled is determined as the scheduled beam position for the downlink time slot. The satellite base station may determine the time slot position of the uplink time slot corresponding to the downlink time slot based on the uplink and downlink scheduling time slot interval determined above. Furthermore, the satellite base station may determine the scheduling beam position of the downlink time slot as the scheduling beam position of the uplink time slot, and obtain the uplink and downlink beam position scheduling result for the time slot.

[0094] For example, Figure 7As shown, the cell-level round-trip transmission delay is 10 time slots, and the upper limit of the satellite base station's scheduling timing range is 8 time slots. It can be understood that the upper limit of the uplink and downlink scheduling time slot interval is 18 time slots, and the lower limit of the time slot position of the uplink time slot is 10 time slots. For each time slot in the semi-static beam position scheduling pattern, when the downlink time slot of the time slot is a static time slot, the satellite base station can determine the beam position indicated by the beam position attribution identifier corresponding to the downlink time slot as the scheduling beam position of the downlink time slot. The satellite base station can determine a reasonable uplink and downlink scheduling time slot interval based on the cell-level round-trip transmission delay (i.e., 10 time slots) and the satellite base station's scheduling timing range (i.e., 0 to 8 time slots), and determine the time slot position of the uplink time slot corresponding to the downlink time slot based on the uplink and downlink scheduling time slot interval (e.g., 12 time slots). Furthermore, the satellite base station can determine the scheduling beam position of the downlink time slot as the scheduling beam position of the uplink time slot, obtaining the uplink and downlink beam position scheduling result for the time slot. When the downlink timeslot in question is a dynamic timeslot, the beam position with the highest scheduling priority in the current list of beam positions to be scheduled is determined as the scheduled beam position for the downlink timeslot. The satellite base station can determine the time slot position of the uplink timeslot corresponding to the downlink timeslot based on the uplink and downlink scheduling time slot interval determined above. Furthermore, the satellite base station can determine the scheduled beam position of the downlink timeslot as the scheduled beam position of the uplink timeslot, obtaining the uplink and downlink beam position scheduling results for the targeted timeslot. For example, if the beam position attribution identifier for the downlink timeslot corresponding to slot 4 of SFN0 is SSB index 0, then the beam position attribution identifier for the uplink timeslot corresponding to slot 2 of SFN1, which is bound to it, is also SSB index 0.

[0095] In the above embodiment, for each time slot in the semi-static beam scheduling pattern, if the downlink time slot in question is a static time slot, the beam position indicated by the beam position attribution identifier corresponding to the downlink time slot is determined as the scheduled beam position for the downlink time slot. Furthermore, the time slot position of the uplink time slot corresponding to the downlink time slot is directly determined based on the uplink and downlink scheduling time slot interval. This improves the efficiency of obtaining uplink and downlink beam scheduling results for each time slot.

[0096] In one embodiment, performing terminal-level time domain scheduling on each terminal in the wavelet user queue under the determined wavelet includes: performing terminal-level time domain scheduling on each terminal in the wavelet user queue under the wavelet according to its buffered data amount to be scheduled.

[0097] For example, Figure 8As shown, the satellite base station maintains a waveband user queue. Each user queue for waveband x (i.e., UEx1, UEx2, ..., UExm) contains at least one user terminal (UE) accessing that waveband. The satellite base station sequentially adds each terminal for waveband x to the waveband user queue in the order of access. It will be appreciated that when a new terminal accesses waveband z, a new user queue for waveband z is created under the waveband user queue and the new terminal is added to the waveband z user queue.

[0098] It should be understood that, although the various steps in the flow chart of the above-mentioned embodiments are shown in sequence, these steps are not necessarily performed in sequence. Unless clearly stated herein, the execution of these steps does not have strict order restrictions, and these steps can be performed in other sequences. Moreover, at least a portion of the steps in the above-mentioned embodiments may include a plurality of sub-steps or a plurality of stages, and these sub-steps or stages are not necessarily performed at the same time, but can be performed at different times, and the execution order of these sub-steps or stages is not necessarily performed in sequence, but can be performed in turn or alternately with at least a portion of other steps or sub-steps or stages of other steps.

[0101] The configuration module 904 is used to configure the starting position of the system message according to the window offset and the sending period.

[0102] In one embodiment, the starting position of the system message includes the system frame number SFN and the time slot number a, which satisfies the following formula:

[0103] (SFN-Offset)%T=FLOOR(x / N);

[0108] Where: n is the target number of the system message, and w is the window length of the system message.

[0109] The above-mentioned system message configuration device obtains the window offset and sending period of the system message; configures the starting position of the system message according to the window offset and sending period, and can flexibly configure the system message in the non-terrestrial network, thereby improving the communication efficiency of the non-terrestrial network.

[0110] In one embodiment, Figure 10 As shown, a beam position scheduling device 1000 is provided, which is applied to a satellite base station. The beam coverage range of the satellite base station is divided into multiple beam positions. The device specifically includes:

[0118] In one embodiment, the scheduling module 1006 is also used to, for each time slot in the semi-static wave position scheduling pattern, determine the wave position indicated by the wave position belonging identifier corresponding to the time slot as the scheduling wave position of the time slot, and obtain the wave position scheduling result of the time slot; when the time slot is a dynamic time slot, determine the wave position with the highest scheduling priority in the current list of wave positions to be scheduled as the scheduling wave position of the time slot.
