Description

Technical Field

[0001] This application relates to the field of integrated space-ground networks, and in particular to a scheduling method and device, base station, storage medium, and computer program product. Background Technology

[0002] Currently, satellite communication networks and terrestrial networks generally adopt a frequency-separated construction approach to avoid inter-system interference risks and reduce deployment difficulty. However, low-frequency bands below 6GHz, suitable for direct mobile phone connections to satellites, are scarce and have low spectrum utilization, making it difficult to allocate independently usable frequency bands for low-Earth orbit satellite networks. Satellite-ground spectrum sharing is a potential solution, but severe co-channel interference between satellites and ground stations must be avoided.

[0003] Existing satellite-ground frequency sharing methods are mostly based on pre-configured interference avoidance methods such as frequency isolation and spatial isolation. In essence, they only consider independent satellite networking, resulting in low flexibility in resource scheduling and low spectrum utilization efficiency. Summary of the Invention

The accompanying drawings are for reference and illustration only and are not intended to limit the embodiments of this application.

The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0041] In the following description, references to "some embodiments" refer to a subset of all possible embodiments. It is understood that "some embodiments" may be the same or different subsets of all possible embodiments and may be combined with each other without conflict. It should also be noted that the terms "first, second, third" used in the embodiments of this application are merely for distinguishing similar objects and do not represent a specific ordering of objects. It is understood that "first, second, third" may be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.

[0042] This application provides a scheduling method, such as... Figure 1 As shown, when applied to a scheduling device, the method may include:

[0043] S101. Obtain the first information at the wavelet level; the first information includes, but is not limited to: Physical Resource Block (PRB) service requirement information, PRB utilization information, and uplink / downlink interference information.

[0044] The scheduling method provided in this application embodiment is applicable to scenarios involving satellite-to-ground frequency sharing.

[0045] In this embodiment, the scheduling device is a functional node, and its deployment method can be independent or set on a certain network device, etc. The specific deployment method can be determined according to the actual situation, and this application does not impose specific limitations on its deployment method.

[0046] In one embodiment, the first information at the wavelength level is the first information of the NTN cell at the wavelength level. The Non-Terrestrial Network (NTN) base station can periodically provide the first information of the NTN cell at the wavelength level to the scheduling device.

[0047] In one embodiment, the first information at the wavelength level includes the first information of the NTN cell at the wavelength level and the first information of the cellular cell at the wavelength level. In this case, the scheduling device can periodically receive the first information of the NTN cell at the wavelength level sent by the NTN base station; and can periodically acquire the first information of the cellular cell at the wavelength level.

[0048] It should be noted that the scheduling equipment obtains the first information of the cell at the spectral level in two ways. The specific method to be used can be selected based on the actual situation; this application does not impose specific limitations on the embodiments.

[0049] In one optional embodiment, the first information of the cell at the wavelength level is received from the network management device; the first information of the cell at the wavelength level is obtained by the network management device converting the first information of the cell at the cell level sent by the cellular base station based on a preset wavelength planning table and pre-stored cell location information.

[0050] It should be noted that, in this embodiment of the application, the network management device stores a preset wavelength planning table, the cellular base station sends the cell-level first information of the cellular cell to the network management device, the network management device pre-stores the cell location information, and the network management device can normalize the cell-level first information of the cellular cell sent by the cellular base station to the wavelength-level first information of the cellular cell based on the preset wavelength planning table and the pre-stored cell location information. After that, the network management device sends the wavelength-level first information of the cellular cell to the scheduling device.

[0051] It should be noted that the network management device can be connected to the scheduling device through at least one level of network management device, and the gateway device can send the first information of the cellular cell at the wavelength level to the scheduling device through at least one level of network management device. Alternatively, the network management device can be directly connected to the scheduling device and directly send the first information of the cellular cell at the wavelength level to the scheduling device. The specific choice can be made according to the actual situation, and this application embodiment does not make specific limitations.

[0052] It should be noted that the cell location information may include cell geographic location information and wave position latitude and longitude information, etc. The specific selection can be made according to the actual situation, and this application embodiment does not impose specific limitations.

[0053] In another optional embodiment, cell-level cellular information sent by a cellular base station is received, the cellular information including at least one of the following: first information of the cellular cell, cell location information; and based on a preset wavelength planning table and cellular message location information, the cell-level first information of the cellular cell is converted into wavelength-level first information of the cellular cell.

[0054] It should be noted that, in this embodiment, the scheduling device stores a preset wavelet planning table. The cellular base station can directly send cell-level cellular information to the scheduling device, or send cell-level cellular information to the scheduling device through at least one level of network management equipment. The specific choice can be made according to the actual situation, and this embodiment does not impose any specific limitations.

[0055] It should be noted that the scheduling equipment normalizes the first information of the cell at the cell level to the first information of the cell at the cell level based on the preset wavelet planning table and cellular message location information.

[0056] It should be noted that the first information of a cellular cell includes at least one of the following: the cell's PRB service requirements and PRB utilization status. The specific information can be selected according to the actual situation, and this application embodiment does not impose any specific limitations.

[0057] Furthermore, before acquiring the first information at the wavelet level, a wavelet information determination process is also performed. Specifically, the scheduling device receives the second information sent by the NTN base station and the third information sent by the cellular base station. The second information includes at least one of the following: satellite ephemeris information, first radio frequency information, and measured uplink and downlink interference information. The third information includes at least one of the following: cell location information and second radio frequency information. Afterward, the scheduling device determines the wavelet information based on the first and second information and sends the wavelet information to the NTN base station so that the NTN base station can select the wavelet information for communication services.

[0058] It should be noted that the scheduling device obtains the third information sent by the cellular base station through the wireless network management system, or the scheduling device obtains the third information directly from the cellular base station. The specific choice can be made according to the actual situation, and this application embodiment does not impose specific limitations.

[0059] It should be noted that the wave position information determined by the scheduling equipment based on the first and second information is wave position information that meets the requirements of satellite-to-ground neighbor cell compatibility.

[0060] In one embodiment, the scheduling device can perform interference simulation based on satellite ephemeris information, first radio frequency information, cell location information, and second radio frequency information to simulate the interference information between the ground and the satellite. Then, the simulated interference information is compared with the interference threshold. If the interference threshold is not exceeded, it means that the corresponding wavelet information meets the satellite-to-ground adjacent channel compatibility requirements. Then, the wavelet information that meets the satellite-to-ground adjacent channel compatibility requirements is corrected based on the measured uplink and downlink interference information to obtain the final wavelet information that meets the satellite-to-ground adjacent cell compatibility requirements.

[0061] It should be noted that the measured uplink and downlink interference information included in the second information can be the same as the uplink and downlink interference information in the first information. The specific selection can be made according to the actual situation, and this application embodiment does not impose specific limitations.

[0062] It should be noted that since this scheme essentially transforms the co-channel scenario to the adjacent-channel scenario through frequency allocation, the NTN base station must select a frequency band that meets the compatibility requirements of the adjacent-channel scenario for service; otherwise, there will be serious interference.

[0063] S102. Based on the first information, the satellite-ground shared frequency is divided so that NTN base stations and / or TN base stations can perform terminal scheduling on the divided satellite-ground shared frequency.

[0064] In one embodiment, when the first information at the wavelet level is the first information of the NTN cell at the wavelet level, the scheduling device performs algorithm optimization based on the first information of the NTN cell at the wavelet level to divide the satellite-ground shared frequency and obtain a first frequency band. Here, the first frequency band is the frequency band used by the satellite network, and the corresponding frequency band division parameters can be at the wavelet level.

[0065] In another embodiment, where the first information at the wavelet level includes the first information of the NTN cell at the wavelet level and the first information of the cellular cell at the wavelet level, the scheduling device can also divide the satellite-ground shared frequency into a first frequency band, a second frequency band, and a third frequency band based on the first information; then, it sends the first frequency band and the third frequency band to the NTN base station; and sends the second frequency band and the third frequency band to the cellular base station.

[0066] Optionally, the scheduling equipment performs algorithm optimization based on the first information of the NTN cell at the wavelet level and the first information of the cellular cell at the wavelet level, dividing the satellite-ground shared frequency into a first frequency band, a second frequency band, and a third frequency band. The first frequency band is used by the satellite network, the second frequency band by the cellular network, and the third frequency band is a soft frequency reuse band. The corresponding frequency band division parameters can be at the wavelet level.

[0067] It should be noted that when the service demand of satellite networks and / or terrestrial networks increases and exceeds the allocated frequency band range, NTN base stations and / or cellular base stations will be scheduled on soft frequency reuse bands.

[0068] In this application embodiment, the algorithm optimization criteria for the above two partitioning methods are as follows: the PRB service demand and PRB utilization of satellite network and / or cellular network will affect the frequency band ratio used by satellite network and / or cellular network, showing a positive correlation; the uplink and downlink interference intensity will affect the proportion of soft frequency reuse frequency band, and the greater the interference intensity, the smaller the soft frequency reuse frequency band, showing a negative correlation.

[0069] Furthermore, in the context of satellite-to-ground frequency sharing, downlink wide-area terrestrial networks will be subject to interference, while uplink wide-area terrestrial networks will experience lumped interference. Therefore, for the allocation of frequency bands for satellite networks, cellular networks, and soft frequency reuse for each wavelet, the wavelet-level parameters within its coverage area will affect the allocation of frequency bands to a certain extent. This proportion is directly proportional to the interference intensity brought by the corresponding wavelet, and the interference intensity is related to the relative positional relationship between the satellite and the wavelet, as well as the antenna gain.

[0070] It should be noted that NTN base stations and cellular base stations prioritize scheduling terminals within their own network's frequency band. If the PRB demand exceeds the frequency band range used by the network, terminals with weaker signal strength will be scheduled within the network's frequency band, while terminals with stronger signal strength will be scheduled within the soft frequency reuse band. This is to account for potential collisions between satellite and ground co-frequency resources in the soft frequency reuse band, and terminals with stronger signal strength have stronger anti-interference capabilities.

[0071] Furthermore, before allocating the satellite-ground shared frequency based on the first information, the scheduling equipment also predicts the satellite-ground PRB change information based on the historical first information; and predicts the future allocation parameters of the satellite-ground shared frequency based on the satellite-ground PRB change information; and / or determines the future allocation parameters based on the historical allocation parameters of the satellite-ground shared frequency.

[0072] Specifically, the scheduling equipment can be trained based on historical first information to obtain more comprehensive and fine-grained trends in PRB service demand and utilization of satellite and terrestrial networks, and can predict PRB service demand and utilization in the future.

[0073] Specifically, the scheduling equipment can also predict future allocation parameters directly based on historical allocation parameters of the satellite-ground shared frequency.

[0074] In practical applications, either of the two methods can be selected and implemented. The specific choice can be made according to the actual situation, and the embodiments in this application do not impose specific limitations.

[0075] Accordingly, when the change in the future allocation parameters and the current allocation parameters of the satellite-to-ground shared frequency exceeds a preset threshold, the scheduling equipment will distribute the allocated satellite-to-ground shared frequency. If the change does not exceed the preset threshold, the frequency allocation parameters will not be updated.

[0076] It should be noted that the frequency of distributing the partitioning parameters for satellite-to-ground sharing can be determined more efficiently based on the predicted future partitioning parameters.

[0077] It should be noted that the change information includes the range of change, duration, etc., and the specific selection can be made according to the actual situation. This application embodiment does not make specific limitations.

[0078] It should be noted that satellite-ground networks may cause collisions of satellite and ground frequency resources in the frequency band used by the satellite. NTN base stations will adjust the frequency used according to the frequency selection characteristics to ultimately construct satellite-ground adjacent frequency scenarios.

[0079] Understandably, by collecting wavelet-level service demand information, PRB utilization information, and / or uplink / downlink interference information to allocate satellite-ground shared frequencies, it is possible to maximize the adaptation to satellite service needs and improve the flexibility of resource scheduling. Since the PRB utilization rate of terrestrial networks is low, sharing satellite-ground shared frequencies with satellite networks can also improve spectrum utilization.

[0080] This application provides a scheduling method, such as... Figure 2 As shown, when applied to an NTN base station, the method may include:

[0081] S201. Send the first information of the NTN cell at the wavelet level to the scheduling equipment.

[0082] Furthermore, before sending the first information of the NTN cell at the wavelength level to the scheduling equipment, the NTN base station first sends the second information to the scheduling equipment; the second information includes at least one of the following: satellite ephemeris information, first radio frequency information, and measured uplink and downlink interference information; and receives the wavelength information sent by the scheduling equipment to select the wavelength information for communication service.

[0083] It should be noted that since this scheme essentially transforms the co-channel scenario to the adjacent-channel scenario through frequency allocation, the NTN base station must select a frequency band that meets the compatibility requirements of the adjacent-channel scenario for service; otherwise, there will be serious interference.

[0084] Furthermore, in one embodiment, after sending the first information of the NTN cell at the wavelet level to the scheduling device, the NTN base station also receives the first frequency band sent by the scheduling device and performs terminal scheduling on the first frequency band.

[0085] Furthermore, in one embodiment, after the NTN base station sends the first information of the NTN cell at the wavelength level to the scheduling device, it can also receive the first frequency band and the third frequency band sent by the scheduling device.

[0086] It should be noted that the NTN base station only receives signals in the first frequency band, which is a loosely coupled satellite-to-ground scenario. This scenario occurs when the terrestrial network lacks the ability to actively report relevant information, or reports information only on an hourly basis; the terrestrial network does not support adjusting the time-frequency resources to be scheduled based on the control node's requirements. In this case, the scheduling equipment only constrains the frequency band used by the NTN base station.

[0087] It should be noted that the NTN base station receives signals in the first and second frequency bands under a tightly coupled satellite-to-ground scenario. This scenario involves the terrestrial network having the capability to actively report relevant information frequently, and the terrestrial network supporting adjustments to the time-frequency resources to be scheduled based on the control node's requirements. In this case, the scheduling equipment constrains the frequency bands used by both the NTN base station and the cellular base station.

[0088] Accordingly, terminal scheduling is performed on the first frequency band; or, when the PRB demand is greater than the capacity of the first frequency band, the first terminal is scheduled first on the first frequency band and the second terminal is scheduled on the third frequency band; the signal strength of the first terminal is less than the signal strength of the second terminal.

[0089] It should be noted that NTN base stations prioritize scheduling terminals within their own network's frequency band. If the PRB demand exceeds the available frequency band range, terminals with weaker signal strength will be scheduled within the network's available frequency band, while terminals with stronger signal strength will be scheduled within the soft frequency reuse band. This is to account for potential collisions between satellite and ground co-frequency resources in soft frequency reuse bands, and terminals with stronger signal strength have stronger anti-interference capabilities.

[0090] Understandably, by collecting wavelet-level service demand information, PRB utilization information, and / or uplink / downlink interference information to allocate satellite-ground shared frequencies, it is possible to maximize the adaptation to satellite service needs and improve the flexibility of resource scheduling. Since the PRB utilization rate of terrestrial networks is low, sharing satellite-ground shared frequencies with satellite networks can also improve spectrum utilization.

[0091] This application provides a scheduling method, such as... Figure 3 As shown, when applied to a cellular base station, the method may include:

[0092] S301. Send cell-level first information of a cellular unit to the network management device, and / or send cell-level cellular information to the scheduling device; the cellular information includes at least one of the following: first information of a cellular unit, cell location information; so that the network management device can convert the cell-level first information of a cellular unit into the first information of a cellular unit at the frequency level based on a preset frequency planning table and pre-stored cell location information and send it to the scheduling device, and / or so that the scheduling device can convert the cell-level first information of a cellular unit into the first information of a cellular unit at the frequency level based on a preset frequency planning table and cellular message location information.

[0093] It should be noted that the method of cellular base station participation in scheduling is applicable to satellite-ground tightly coupled scenarios. In such scenarios, the ground network has the ability to actively report relevant information and reports it frequently, and the ground network supports adjusting the time and frequency resources to be scheduled according to the needs of the control node.

[0094] In this embodiment, the scheduling device and the cellular base station can communicate directly or through at least one wireless network management system. The specific choice can be made according to the actual situation, and this embodiment does not impose any specific limitations.

[0095] It should be noted that since the preset wavelet planning table can be set in the network management device or the scheduling device, the conversion of the first information of the cell at the cell level can be performed by either the network management device or the scheduling device.

[0096] It should be noted that since the network management device can obtain the location information of the cellular base station, when the network management device performs the conversion of the first information of the cell at the cell level, the cellular base station can only send the first information of the cell at the cell level to the network management device.

[0097] It should be noted that when the cellular base station cannot determine whether the preset wavelength planning table is set in the network management equipment or the scheduling equipment, the cellular base station can directly report cellular cell information. The specific choice can be made based on the actual situation, and this application embodiment does not impose specific limitations.

[0098] Furthermore, before sending the first cell-level cellular information to the network management device and / or sending the cell-level cellular information to the scheduling device, a third piece of information is first sent to the scheduling device; the third piece of information includes at least one of the following: cell location information and second radio frequency information; the third piece of information is used by the scheduling device to determine the beam position information.

[0099] S302, Receive the second and third frequency bands sent by the scheduling equipment.

[0100] In this embodiment, terminal scheduling can be performed on the second frequency band; alternatively, when the PRB demand exceeds the capacity of the second frequency band, the third terminal is prioritized for scheduling on the second frequency band, and the fourth terminal is scheduled on the third frequency band; the signal strength of the third terminal is less than that of the fourth terminal. The specific choice can be made based on actual circumstances, and this embodiment does not impose any specific limitations.

[0101] It should be noted that cellular base stations prioritize scheduling terminals within their own network's frequency band. If the PRB demand exceeds the available frequency band range of the network, terminals with weaker signal strength will be scheduled within the network's available frequency band, while terminals with stronger signal strength will be scheduled within the soft frequency reuse band. This is to account for potential collisions between satellite and ground frequency resources in soft frequency reuse bands, and terminals with stronger signal strength have stronger anti-interference capabilities.

[0102] Understandably, by collecting wavelet-level service demand information, PRB utilization information, and / or uplink / downlink interference information to allocate satellite-ground shared frequencies, it is possible to maximize the adaptation to satellite service needs and improve the flexibility of resource scheduling. Since the PRB utilization rate of terrestrial networks is low, sharing satellite-ground shared frequencies with satellite networks can also improve spectrum utilization.

[0103] Based on the above embodiments, a scheduling method for tightly coupled space-ground scenarios is proposed, such as... Figure 4 As shown, the method may include:

[0104] 1. The cellular base station sends third information to the scheduling equipment; the third information includes at least one of the following: cell location information and second radio frequency information.

[0105] 2. The NTN base station sends second information to the scheduling equipment; the second information includes at least one of the following: satellite ephemeris information, first radio frequency information, and measured uplink and downlink interference information.

[0106] 3. The scheduling equipment determines the wave position information based on the third and second information.

[0107] 4. The scheduling equipment sends waveform information to the NTN base station so that the NTN base station can select the waveform information for communication services.

[0108] 5. The NTN base station sends the first information of the NTN cell at the wavelet level to the scheduling equipment.

[0109] 6. The cellular base station sends cell-level cellular information to the scheduling equipment. The cellular information includes at least one of the following: first information of the cellular cell and location information of the cellular cell.

[0110] 7. The scheduling equipment converts the first information of the cell at the cell level into the first information of the cell at the cell level based on the preset wavelet planning table and cellular message location information.

[0111] 8. The cellular base station sends the first cell-level information of the cellular unit to the network management equipment.

[0112] 9. Based on the preset wavelet planning table and the pre-stored cell location information, the network management equipment converts the cell-level first information of the cell sent by the cellular base station to obtain the wavelet-level first information of the cell.

[0113] 10. The network management equipment sends the first information of the cell at the wavelet level to the dispatching equipment.

[0114] 6-7 and 8-10 are two parallel solutions, and the specific solution can be selected and implemented according to the actual situation. This application does not impose specific limitations on the embodiments.

[0115] 11. The scheduling equipment divides the satellite-ground shared frequency into a first frequency band, a second frequency band, and a third frequency band based on the first information of the cellular cell at the wavelet level and the first information of the NTN cell at the wavelet level.

[0116] 12. The scheduling equipment predicts satellite-to-ground PRB change information based on the first information of cellular cells at the historical wavelet level and the first information of NTN cells at the historical wavelet level; and predicts future allocation parameters of satellite-to-ground shared frequency based on the satellite-to-ground PRB change information.

[0117] 13. The scheduling equipment determines the future allocation parameters based on the historical allocation parameters of the satellite-ground shared frequency.

[0118] 14. When the change information between the future partitioning parameters and the current partitioning parameters of the satellite-ground shared frequency exceeds a preset threshold, the scheduling device sends the first frequency band and the third frequency band to the NTN base station.

[0119] 15. When the change information between the future partitioning parameters and the current partitioning parameters of the satellite-ground shared frequency exceeds a preset threshold, the scheduling device sends the second and third frequency bands to the cellular base station.
