[0029] The steps of the resource scheduling method in the exemplary embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings and examples.

[0030] Figure 1This is a flowchart illustrating a resource scheduling method according to an exemplary embodiment. The method provided in this disclosure can be executed by a time-frequency-spatial joint scheduler, and the method provided in this disclosure can be applied to wireless communication scenarios such as 5G or 5G SA (Standalone) co-construction and sharing networks, but this disclosure is not limited thereto.

[0031] like Figure 1 As shown, the resource scheduling method provided in this embodiment may include the following steps.

[0032] In step S102, each target terminal under the overlapping coverage area of ​​the first shared base station and the second shared base station is determined.

[0033] In an exemplary embodiment, the first shared base station is a TDD (Time Division Duplexing) shared base station, and the second shared base station is an FDD (Frequency Division Duplexing) shared base station.

[0034] In this embodiment of the disclosure, the first shared base station and the second shared base station may be located at the same site or not, and the first shared base station and the second shared base station have overlapping coverage areas.

[0035] For example, the first shared base station can be a 3.5G TDD shared SA base station with 7 narrow beams of SSB (Synchronization Signal block); the second shared base station can be a 2.1G FDD shared SA base station with 1 to 4 wide beams of SSB.

[0036] In some embodiments, the coverage area of ​​a 2.1G FDD shared SA base station may include the coverage area of ​​a 3.5G TDD shared SA base station, but this disclosure is not limited thereto.

[0037] In this embodiment of the disclosure, both the first shared base station and the second shared base station can be communicatively connected to the time-frequency-spatial joint scheduler. The time-frequency-spatial joint scheduler can obtain information about the first shared base station and the second shared base station, and schedule each target terminal in the overlapping coverage area of ​​the first shared base station and the second shared base station according to the obtained information.

[0038] In this embodiment of the disclosure, the terminal located in the overlapping coverage area of ​​the first shared base station and the second shared base station is referred to as the target terminal. There may be one or more target terminals, and this disclosure does not limit the number of target terminals.

[0039] In step S104, the time domain resources, frequency domain resources, and spatial domain resources of each target terminal corresponding to the first shared base station are determined, as well as the time domain resources, frequency domain resources, and spatial domain resources of each target terminal corresponding to the second shared base station.

[0040] Figure 2 This is a schematic diagram illustrating the time-domain resources, frequency-domain resources, and spatial-domain resources corresponding to each target terminal, as shown in the example.

[0041] refer to Figure 2 Taking the existence of 3 target terminals (UE1, UE2, UE3) as an example, the time domain resources, frequency domain resources and spatial domain resources of these 3 target terminals corresponding to the first shared base station are determined respectively, as well as the time domain resources, frequency domain resources and spatial domain resources of these 3 target terminals corresponding to the second shared base station.

[0042] In this embodiment of the disclosure, time-domain resources may include, but are not limited to, the time slots corresponding to each target terminal; frequency-domain resources may include, but are not limited to, the bandwidth allocated to each target terminal on each beam; and spatial-domain resources may include, but are not limited to, the precoding matrix and channel matrix corresponding to the first bandwidth allocated to each target terminal on each beam.

[0043] In step S106, the first maximum channel capacity corresponding to the first shared base station is determined based on the time domain resources, frequency domain resources, and spatial domain resources corresponding to each target terminal at the first shared base station, and the second maximum channel capacity corresponding to the second shared base station is determined based on the time domain resources, frequency domain resources, and spatial domain resources corresponding to each target terminal at the second shared base station.

[0044] In this embodiment of the disclosure, an improved Shannon formula can be used to calculate the first maximum channel capacity corresponding to the first shared base station based on the time-domain resources, frequency-domain resources, and spatial-domain resources corresponding to each target terminal at the first shared base station; and to determine the second maximum channel capacity corresponding to the second shared base station based on the time-domain resources, frequency-domain resources, and spatial-domain resources corresponding to each target terminal at the second shared base station.

[0045] In this embodiment of the disclosure, there may be multiple first resource allocation strategies, each corresponding to an allocation method for time-domain resources, frequency-domain resources, and spatial-domain resources. The channel capacity is calculated based on the allocation method of each time-domain resource, frequency-domain resource, and spatial-domain resource, and the largest channel capacity is taken as the first maximum channel capacity. Similarly, there may be multiple second resource allocation strategies, each corresponding to an allocation method for time-domain resources, frequency-domain resources, and spatial-domain resources. The channel capacity is calculated based on the allocation method of each time-domain resource, frequency-domain resource, and spatial-domain resource, and the largest channel capacity is taken as the second maximum channel capacity.

[0046] In step S108, a target shared base station is determined based on the first maximum channel capacity and the second maximum channel capacity, so that each target terminal can communicate with the target shared base station.

[0047] In this embodiment of the disclosure, the first shared base station or the second shared base station can be used as the target shared base station based on the values ​​of the first maximum channel capacity and the second maximum channel capacity, and each target terminal can be switched to the target shared base station.

[0048] In an exemplary embodiment, determining a target shared base station based on a first maximum channel capacity and a second maximum channel capacity includes: if the first maximum channel capacity is greater than or equal to the second maximum channel capacity, then determining the first shared base station as the target shared base station; if the first maximum channel capacity is less than the second maximum channel capacity, then determining the second shared base station as the target shared base station.

[0049] In this embodiment of the disclosure, a channel capacity threshold can also be set. If the first maximum channel capacity is greater than or equal to the second maximum channel capacity, and the first maximum channel capacity is greater than the channel capacity threshold, then the first shared base station is determined as the target shared base station; if the first maximum channel capacity is less than the second maximum channel capacity, and the second maximum channel capacity is greater than the channel capacity threshold, then the second shared base station is determined as the target shared base station.

[0050] Figure 3 This is a schematic diagram illustrating the handover of a target terminal using a time-frequency-spatial joint scheduler, as shown in an example.

[0051] For example, refer to Figure 3 In (1), assuming the maximum channel capacity of a 2.1G FDD shared SA base station is greater than that of a 3.5G TDD shared SA base station, then migrating the target terminal from TDD to FDD can achieve offloading of one or more beam capacities of TDD; see reference. Figure 3 In (2), assuming that the maximum channel capacity of the 3.5G TDD shared SA base station is greater than that of the 2.1G FDD shared SA base station, then migrating the target terminal from FDD to TDD can improve the TDD MU-MIMO (Multi-User Multiple-Input Multiple-Output) pairing capability and system capacity.

[0052] The resource scheduling method provided in this disclosure determines the first maximum channel capacity corresponding to the first shared base station and the second maximum channel capacity corresponding to the second shared base station based on the time-domain resources, frequency-domain resources, and spatial resources corresponding to each target terminal in the overlapping coverage area of ​​the first shared base station and the second shared base station. The method then determines the target shared base station based on the first and second maximum channel capacities, enabling each target terminal to communicate with the target shared base station. This method can maximize the channel capacity of the shared base station based on time-frequency and spatial resources, dynamically switch between wide and narrow beams, and jointly schedule terminals, thereby improving the overall throughput, spectrum efficiency, and user experience of the shared base station, increasing operation and maintenance efficiency, and saving operation and maintenance costs.

[0053] In an exemplary embodiment, determining the time-domain, frequency-domain, and spatial resources corresponding to each target terminal at the first shared base station, and the time-domain, frequency-domain, and spatial resources corresponding to each target terminal at the second shared base station, may include: acquiring channel state information, reference signal received power, signal-to-noise ratio, and beam identifier of synchronization signal blocks corresponding to each target terminal; acquiring occupancy information of physical resource blocks of each target terminal at the first and second shared base stations; and determining the time-domain, frequency-domain, and spatial resources corresponding to each target terminal at the first and second shared base stations based on the channel state information, reference signal received power, signal-to-noise ratio, beam identifier of synchronization signal blocks, and occupancy information of physical resource blocks of each target terminal at the first and second shared base stations.

[0054] In this embodiment of the disclosure, the time-frequency-spatial joint scheduler can calculate the channel information, interference and noise energy, and user distribution information of each target terminal based on the CSI (Channel State Information) (or SRS (Sounding Reference Signal)), RSRP (Reference Singnal Received Power), SINR (Signal to Interference plus Noise Ratio), and Beam Id (identifier) ​​of SSB (Synchronization Signal block) reported by each target terminal under the overlapping coverage of the 3.5G TDD shared SA base station and the 2.1G FDD shared SA base station; and obtain the PRB (Physical Resource Block) occupancy rate of each 3.5G TDD shared SA base station and the 2.1G FDD shared SA base station.

[0055] In this embodiment, the historical PRB occupancy of each terminal is used as the frequency domain resource reference, the CSI information reported by each terminal in the FDD band or the SRS information (precoding matrix and channel matrix) and location distribution obtained by each terminal from the base station in the TDD band are used as the spatial domain resource reference, and the expected scheduling sequence of each terminal is used as the time domain resource reference. Considering signal, interference and noise energy, based on the improved Shannon formula, the time-frequency and spatial domain resources of the 3.5G TDD shared SA base station and the 2.1G FDD shared SA base station are integrated, and the wide and narrow beams are dynamically switched. The various target terminals are jointly and comprehensively scheduled to achieve the optimal overall channel capacity of the TDD+FDD base station.

[0056] In this embodiment of the disclosure, the above process is repeated continuously. Based on the channel information, interference and noise energy, user distribution and PRB occupancy of each target terminal, the wide and narrow beams are dynamically switched according to the improved Shannon formula. The terminals are jointly and systematically scheduled to improve the overall throughput, spectrum efficiency and user experience of the TDD+FDD shared SA base station, improve the operation and maintenance optimization efficiency and save operation and maintenance optimization costs.

[0057] In an exemplary embodiment, determining the time-domain resources, frequency-domain resources, and spatial resources of each target terminal corresponding to the first shared base station, and the time-domain resources, frequency-domain resources, and spatial resources of each target terminal corresponding to the second shared base station, includes: determining multiple first resource allocation strategies corresponding to the first shared base station, and multiple second resource allocation strategies corresponding to the second shared base station; determining, according to each first resource allocation strategy, a first time slot corresponding to each target terminal, a first bandwidth allocated to each target terminal on each beam, and a first precoding matrix and a first channel matrix corresponding to the first bandwidth allocated to each target terminal on each beam; and determining, according to each second resource allocation strategy, a second time slot corresponding to each target terminal, a second bandwidth allocated to each target terminal on each beam, and a second precoding matrix and a second channel matrix corresponding to the second bandwidth allocated to each target terminal on each beam.

[0058] In this embodiment of the disclosure, the resource allocation strategy corresponding to the first shared base station is referred to as the first resource allocation strategy, the time slot corresponding to each target terminal determined under the first resource allocation strategy is referred to as the first time slot, the bandwidth allocated to each target terminal on each beam under the first resource allocation strategy is referred to as the first bandwidth, and the precoding matrix and channel matrix corresponding to the first bandwidth allocated to each target terminal on each beam are referred to as the first precoding matrix and the first channel matrix. Similarly, the resource allocation strategy corresponding to the second shared base station is referred to as the second resource allocation strategy, the time slot corresponding to each target terminal determined under the second resource allocation strategy is referred to as the second time slot, the bandwidth allocated to each target terminal on each beam under the second resource allocation strategy is referred to as the second bandwidth, and the precoding matrix and channel matrix corresponding to the second bandwidth allocated to each target terminal on each beam are referred to as the second precoding matrix and the second channel matrix.

[0059] In an exemplary embodiment, determining the first maximum channel capacity corresponding to the first shared base station based on the time-domain resources, frequency-domain resources, and spatial resources corresponding to each target terminal at the first shared base station, and determining the second maximum channel capacity corresponding to the second shared base station based on the time-domain resources, frequency-domain resources, and spatial resources corresponding to each target terminal at the second shared base station, includes: determining each first channel capacity corresponding to each first resource allocation strategy based on the first time slot corresponding to each target terminal, the first bandwidth allocated to each target terminal on each beam, and the first precoding matrix and first channel matrix corresponding to the first bandwidth allocated to each target terminal on each beam; determining each second channel capacity corresponding to each second resource allocation strategy based on the second time slot corresponding to each target terminal, the second bandwidth allocated to each target terminal on each beam, and the second precoding matrix and second channel matrix corresponding to the second bandwidth allocated to each target terminal on each beam; and determining the largest first channel capacity among the first channel capacities as the first maximum channel capacity, and determining the largest second channel capacity among the second channel capacities as the second maximum channel capacity.

[0060] In this embodiment of the disclosure, the improved Shannon formula can be used to calculate the first maximum channel capacity corresponding to the first shared base station and the second maximum channel capacity corresponding to the second shared base station. The following description takes the calculation of the first maximum channel capacity corresponding to the first shared base station as an example. The calculation process of the second maximum channel capacity corresponding to the second shared base station is similar and will not be repeated here.

[0061] In this embodiment of the disclosure, the improved Shannon formula is as follows:

[0062]

[0063] Where C represents the channel capacity, K represents the number of target terminals, N represents the total number of beams used by all target terminals under the same spectrum, and α k (t) indicates whether the target terminal k uses air interface resources in the t-th time slot, b k,n (t) represents the bandwidth allocated to the target terminal k on beam n, w k,n,b h represents the precoding matrix corresponding to the bandwidth b allocated to the target terminal k on beam n. k,n,b This represents the channel matrix corresponding to the bandwidth b allocated to the target terminal k on beam n.

[0064] T is determined by the quotient of the radio frame length (10ms) and the time-domain scheduling unit. For a 2.1G FDD base station, the SCS (Subcarrier Spacing) is 15kHz and one time-domain scheduling unit is 1ms, so T is 10; for a 3.5G TDD base station, the SCS is 30kHz and one time-domain scheduling unit is 0.5ms, so T is 20.

[0065] In this embodiment of the disclosure, the first time slot corresponding to each target terminal under each first resource allocation strategy, the first bandwidth allocated to each target terminal on each beam, and the first precoding matrix and the first channel matrix corresponding to the first bandwidth allocated to each target terminal on each beam can be input into the above formula to obtain the first channel capacity corresponding to each first resource allocation strategy, and the largest first channel capacity is taken as the first maximum channel capacity.

[0066] In an exemplary embodiment, the method further includes: when the target shared base station is a first shared base station, using a first resource allocation strategy corresponding to the first maximum channel capacity as a target resource allocation strategy; when the target shared base station is a second shared base station, using a second resource allocation strategy corresponding to the first maximum channel capacity as a target resource allocation strategy; and scheduling each target terminal according to the target resource allocation strategy.

[0067] In this embodiment, if the first maximum channel capacity is greater than or equal to the second maximum channel capacity, the first shared base station is determined as the target shared base station. If the target shared base station is the first shared base station, the first resource allocation strategy corresponding to the first maximum channel capacity is used as the target resource allocation strategy. If the first maximum channel capacity is less than the second maximum channel capacity, the second shared base station is determined as the target shared base station. If the target shared base station is the second shared base station, the second resource allocation strategy corresponding to the first maximum channel capacity is used as the target resource allocation strategy. When scheduling the target terminal subsequently, scheduling is performed according to the allocation scheme of time-domain resources, frequency-domain resources, and spatial resources corresponding to the target resource allocation strategy.
