Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a spectrum sharing method, an electronic device, and a computer-readable storage medium. Background Technology

[0002] With the rapid development of communication technology, the fifth-generation mobile communication technology (5G), characterized by high speed, low latency, large bandwidth, and multiple connections, has emerged. However, because the fourth-generation (4G) and third-generation (3G) mobile communication technologies have been commercially mature for many years, there is a shortage of low- and mid-frequency spectrum resources available for 5G technology. The available spectrum resources below 3.5 GHz have been almost entirely allocated to 3G and 4G technologies. To meet the high bandwidth requirements of 5G technology, operators generally refarm existing spectrum resources or multiple operators share a large block of spectrum resources, implementing carrier merging at the baseband side for spectrum sharing.

[0003] However, in the early stages of 5G technology deployment, the number of commercial terminals is relatively small, and related spectrum sharing technologies are prone to wasting bandwidth resources. In the later stages of 5G technology deployment, the number of commercial terminals increases exponentially and eventually all are upgraded to 5G terminals. The related spectrum sharing technologies can only support 5G bandwidth of no more than 20MHz, which cannot meet the high bandwidth configuration requirements of 5G technology and cannot support the performance of 5G technology. Summary of the Invention

[0004] The main objective of this application is to propose a spectrum sharing method, an electronic device, and a computer-readable storage medium. The aim is to save baseband resources, improve spectrum utilization, achieve large-bandwidth spectrum sharing, meet the high-bandwidth configuration requirements of 5G technology, and improve the service quality of 5G services.

[0005] To achieve the above objectives, embodiments of this application provide a spectrum sharing method, the method comprising: identifying spectrum overlap among carriers; segmenting carriers with spectrum overlap based on the results of the spectrum overlap identification to obtain target carriers participating in spectrum sharing; adjusting the power of each target carrier; wherein the adjusted target carriers have the same power spectral density; and scheduling service data of a first network standard or a second network standard to be transmitted to any of the adjusted target carriers.

[0006] To achieve the above objectives, embodiments of this application also provide an electronic device, including: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one processor to perform the spectrum sharing method described above.

[0007] To achieve the above objectives, embodiments of this application also provide a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the spectrum sharing method described above.

[0008] The spectrum sharing method, electronic device, and computer-readable storage medium proposed in this application, compared to the technology of multiple communication operators sharing a large spectrum resource and implementing carrier combining at the baseband side, which, due to baseband limitations, can only support a maximum of 20MHz bandwidth spectrum sharing, offers a significant improvement. In this application, if the network management server determines to enable spectrum sharing, it performs spectrum overlap identification on each carrier, divides each carrier based on the identification results to obtain target carriers for spectrum sharing, and adjusts the power of each target carrier to maintain the same power spectral density, thereby establishing cells corresponding to each target carrier and achieving spectrum sharing. In contrast, this application does not perform carrier combining but instead divides overlapping carriers, adjusting the power of each divided carrier so that the divided carriers simultaneously support 4G and 5G technologies, achieving spectrum sharing. This overcomes the bandwidth limitations imposed by the baseband side, saves baseband resources, improves spectrum utilization, and enables large-bandwidth spectrum sharing, meeting the high bandwidth requirements of 5G technology and improving the service quality of 5G services.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the various embodiments of this application will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this application to help readers better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and various changes and modifications based on the following embodiments. The division of the various embodiments below is for the convenience of description and should not constitute any limitation on the specific implementation of this application. The various embodiments can be combined with and referenced by each other without contradiction.

[0018] One embodiment of this application relates to a spectrum sharing method applied to an electronic device, which can be a base station or a server. In this embodiment and the following embodiments, the electronic device is described using a server as an example. The implementation details of the spectrum sharing method of this embodiment are described below. The following content is only for ease of understanding and is not essential for implementing this solution.

[0019] The specific process of the spectrum sharing method in this embodiment can be as follows: Figure 1 As shown, it includes:

[0020] Step 101: Identify spectral overlap for each carrier.

[0021] Specifically, when the server determines that spectrum sharing is required, there may be spectrum overlap between the spectrum of each carrier. The server can first identify the spectrum overlap of each carrier to identify the carriers with spectrum overlap.

[0022] In specific implementations, before identifying spectrum overlap for each carrier, the server can disable carrier frequency too close alarm detection and / or carrier total power alarm detection. Considering that, in principle, carriers with overlapping frequencies are not allowed when spectrum sharing is not required, the presence of carriers with overlapping frequencies (i.e., carrier frequencies set too close or total power too high) could lead to carrier and signal confusion, preventing normal communication services. Therefore, when spectrum sharing is not required, the server performs carrier frequency too close alarm detection and carrier total power alarm detection to ensure that there are no carriers with overlapping frequencies. However, in the embodiments of this application, after the server enables spectrum sharing, spectrum sharing is required, allowing for carriers with overlapping frequencies. There is no need to worry about carrier frequencies being set too close or total power being too high. In this case, the server promptly disables carrier frequency too close alarm detection and / or carrier total power alarm detection, saving detection resources and ensuring that spectrum sharing can proceed normally.

[0023] In one example, the server can send spectrum sharing flags to each cell on a per-cell basis. Each cell then uses the received spectrum sharing flags to identify carrier spectrum overlap, preparing for subsequent carrier splitting.

[0024] Step 102: Based on the results of spectrum overlap identification, segment the carriers with spectrum overlap to obtain each target carrier participating in spectrum sharing.

[0025] Specifically, after identifying spectrum overlap on each carrier, the server can segment the carriers with overlapping spectrum based on the identification results to obtain the target carriers participating in spectrum sharing. Segmenting the carriers with overlapping spectrum isolates the overlapping portion, thus removing the overlapping spectrum and ensuring that subsequent services can operate normally.

[0026] In one example, if a carrier includes spliced ​​carriers, the server can split the spliced ​​carriers into several independent carriers. When the server detects spliced ​​carriers in each carrier, it can first split the spliced ​​carriers into several independent carriers according to the splicing rules. Splitting the spliced ​​carriers into independent carriers can further refine the spectrum, making spectrum sharing more scientific and accurate, and ensuring that communication service data can operate normally on the shared spectrum. For example, Figure 2As shown, after enabling spectrum sharing, the server detects an 80MHz NR carrier, an LTE spliced ​​carrier composed of three 20MHz LTE carriers, and a 20MHz independent LTE carrier in the spectrum. The server performs spectrum overlap detection on these carriers, determining that the 80MHz NR carrier and the two 20MHz LTE carriers in the spliced ​​LTE carrier overlap, while the 20MHz independent LTE carrier does not overlap with any other carrier. Before segmenting the carriers with overlapping spectrum based on the overlap identification results, the server can first split the spliced ​​LTE carrier into three 20MHz independent LTE carriers before performing spectrum segmentation. The server can segment the 80MHz NR independent carrier and the three 20MHz LTE carriers split from the spliced ​​carrier into... Figure 3 The target carriers shown are F with a bandwidth of 40MHz, G with a bandwidth of 20MHz, H with a bandwidth of 20MHz, and I with a bandwidth of 20MHz.

[0027] Step 103: Adjust the power of each target carrier.

[0028] Specifically, after the server identifies the overlapping spectrum and segments the carriers to obtain the target carriers for spectrum sharing, it can adjust the power of each target carrier. The adjusted target carriers have the same power spectral density. By adjusting the power of the segmented target carriers to make their power spectral densities the same, the segmented target carriers can simultaneously support 4G and 5G communication services, ensuring that 4G and 5G communication service data can be scheduled to any target carrier.

[0029] In a practical implementation, the server can send a power adjustment command to the baseband processing unit. The baseband processing unit can adjust the power of each target carrier according to the power adjustment command, so that the power spectral density of each target carrier is the same after adjustment, that is, the power per unit bandwidth of each target carrier is the same.

[0030] In one example, the server determines that there is spectral overlap between an 80MHz NR carrier and two of the three consecutive 20MHz LTE carriers. Based on the overlapping 40MHz bandwidth, the 80MHz NR carrier and the two 20MHz LTE carriers are split into one 40MHz target carrier and two 20MHz target carriers. The original 80MHz NR carrier has a power of 160W, and each of the three consecutive 20MHz LTE carriers has a power of 20W. The server can then adjust the power of the 40MHz target carrier to 80W and the power of the 20MHz target carriers to 40W.

[0031] Step 104: Schedule the service data of the first network standard or the second network standard to be transmitted to any adjusted target carrier.

[0032] In practical implementation, the server adjusts the power of each target carrier to ensure that the power spectral density of each target carrier is the same after adjustment. Then, service data of either the first or second network standard to be transmitted can be scheduled to any of the adjusted target carriers to complete the transmission of the service data of either the first or second network standard. Since the power spectral density of each target carrier is the same after adjustment, it is equivalent to a complete large-bandwidth carrier. Service data of either the first or second network standard to be transmitted can be scheduled to any target carrier, achieving spectrum sharing. This eliminates the bandwidth limitations imposed by the baseband side, saves baseband resources, improves spectrum utilization, realizes large-bandwidth spectrum sharing, meets the high bandwidth configuration requirements of 5G technology, and improves the service quality of 5G services.

[0033] In one example, such as Figure 3 As shown, the service data of the first network standard to be transmitted is 5G technology communication service data. This 5G technology communication service data to be transmitted can be scheduled to a target carrier F with a bandwidth of 40MHz, or it can be scheduled to a target carrier G, a target carrier H with a bandwidth of 20MHz, or a target carrier I with a bandwidth of 20MHz.

[0034] In one example, such as Figure 3 As shown, the service data of the second network standard to be transmitted is 4G technology communication service data. The 4G technology communication service data to be transmitted has been scheduled to a target carrier G with a bandwidth of 20MHz. At this time, the target carrier G with a bandwidth of 20MHz has a problem and needs to be deactivated. The server can reschedule the 4G technology communication service data to be transmitted to a target carrier F with a bandwidth of 40MHz.

[0035] In contrast to the technology where multiple telecom operators share a large spectrum resource and carrier combining is implemented at the baseband side, which, due to baseband limitations, can only support a maximum of 20MHz bandwidth for spectrum sharing, this embodiment, if the network management server determines to enable spectrum sharing, performs spectrum overlap identification on each carrier. Based on the results of the spectrum overlap identification, each carrier is segmented to obtain target carriers for spectrum sharing, and the power of each target carrier is adjusted to maintain the same power spectral density, thereby establishing cells corresponding to each target carrier and achieving spectrum sharing. This embodiment does not perform carrier combining, but instead segments overlapping carriers and adjusts the power of each segmented carrier, enabling the segmented carriers to simultaneously support 4G and 5G technologies, achieving spectrum sharing. This overcomes the bandwidth limitations of the baseband side, saves baseband resources, improves spectrum utilization, achieves large-bandwidth spectrum sharing, meets the high bandwidth configuration requirements of 5G technology, and improves the service quality of 5G services.

[0036] In one embodiment, the server segments carriers with overlapping spectra based on the results of spectrum overlap identification to obtain target carriers participating in spectrum sharing. This can be achieved by, for example... Figure 4 The steps shown are implemented as follows:

[0037] Step 201: Based on the results of spectrum overlap identification, determine the carrier with the smallest bandwidth among the carriers with spectrum overlap.

[0038] Specifically, after identifying the spectral overlap of each carrier, the server can first determine the carrier with the smallest bandwidth among the carriers with spectral overlap based on the results of the spectral overlap identification.

[0039] In one example, such as Figure 5 As shown, after enabling spectrum sharing, the server detects an 80MHz NR carrier, two consecutive 20MHz LTE carriers (denoted as LTE carrier 1 and LTE carrier 2, respectively), and two independent 20MHz LTE carriers (denoted as LTE carrier 3 and LTE carrier 4, respectively). The server performs spectrum overlap detection on these carriers and determines that the 80MHz NR carrier overlaps with LTE carriers 1 and 2, and the 80MHz NR carrier overlaps with LTE carrier 3. The 20MHz LTE carrier 4 does not overlap with any other carrier. Among the carriers with spectrum overlap, the server determines that the carrier with the smallest bandwidth is LTE carrier 1 with a bandwidth of 20MHz.

[0040] Step 202: Based on the bandwidth of the carrier with the smallest bandwidth, the carriers with overlapping spectra are segmented to obtain each target carrier participating in spectrum sharing.

[0041] Specifically, after the server identifies the carrier with the smallest bandwidth among the carriers with overlapping spectrum based on the spectrum overlap identification results, it can segment the carriers with overlapping spectrum according to the bandwidth of the carrier with the smallest bandwidth to obtain each target carrier participating in spectrum sharing. This can ensure the integrity of the carrier with the smallest bandwidth, making the segmented carriers more regular and standardized, which is convenient for subsequent calculations and adjustments.

[0042] In one example, such as Figure 5 As shown, the server determines that there is spectral overlap between an 80MHz NR carrier and 20MHz LTE carriers, and between an 80MHz NR carrier and a 20MHz LTE carrier. Among the carriers with spectral overlap, the carrier with the smallest bandwidth is the 20MHz LTE carrier. The server can then divide each carrier into segments based on the bandwidth of the 20MHz LTE carrier. Figure 6 The target carriers shown are A, B, C, and D, each with a bandwidth of 20MHz.

[0043] In this embodiment, the step of segmenting carriers with overlapping spectra based on the result of the spectrum overlap identification to obtain target carriers participating in spectrum sharing includes: determining the carrier with the smallest bandwidth among the carriers with overlapping spectra based on the result of the spectrum overlap identification; and segmenting the carriers with overlapping spectra based on the bandwidth of the carrier with the smallest bandwidth to obtain target carriers participating in spectrum sharing. This ensures the integrity of the carrier and makes the segmented carriers more regular and standardized, facilitating subsequent calculations and adjustments.

[0044] In one embodiment, after adjusting the power of each target carrier, before scheduling the service data of the first or second network standard to be transmitted to any of the adjusted target carriers, the server can first complete the configuration of the cells corresponding to each target carrier and perform Crest Factor Reduction (CFR) on each target carrier. The server can perform CFR on each target carrier by, for example... Figure 7 The steps shown are implemented as follows:

[0045] Step 301: Activate the cells corresponding to each target carrier.

[0046] In a specific implementation, each carrier corresponds to its own cell. However, in the embodiments of this application, the carriers with overlapping spectra are segmented based on the results of spectrum overlap identification. Therefore, it is necessary to first shut down the cells corresponding to each carrier. After adjusting the power of each target carrier, that is, after completing the configuration of the cells corresponding to each target carrier, the cells corresponding to each target carrier can be activated before scheduling the service data of the first network standard or the second network standard to be transmitted to any adjusted target carrier.

[0047] Step 302: Obtain the occupancy status of the cells corresponding to each target carrier.

[0048] In the specific implementation, after activating the cells corresponding to each target carrier, the server can obtain the blocking status of the cells corresponding to each target carrier by detecting whether the cells corresponding to each target carrier are silent. If the cell corresponding to the target carrier is silent, it means that the cell corresponding to the target carrier is blocked; if the cell corresponding to the target carrier is not silent, it means that the cell corresponding to the target carrier is not blocked.

[0049] In one example, such as Figure 3 As shown, the server detected that the cell corresponding to the target carrier E with a bandwidth of 40MHz was muted, and determined that the cell corresponding to the target carrier F with a bandwidth of 40MHz was blocked.

[0050] Step 303: Based on the occupancy status of the cell corresponding to each target carrier, selectively perform CFR on each target carrier.

[0051] Specifically, after the server obtains the occupancy status of the cells corresponding to each target carrier, it can selectively perform CFR on each target carrier according to the occupancy status of the cells corresponding to each target carrier. CFR can eliminate abnormal signals with excessively large peak values, improve communication quality and comfort. In this embodiment, selectively performing CFR on each target carrier allows for more targeted CFR and effectively saves CFR resources.

[0052] In a practical implementation, the server can call the Field Programmable Gate Array (FPGA) unit of the RF combiner module to selectively perform CFR on each target carrier.

[0053] In one example, if there are unblocked cells among the cells corresponding to each target carrier, CFR is performed on each target carrier. Considering that the power spectral density of each target carrier is the same after adjustment, which is equivalent to a complete large-bandwidth carrier, the service data of the first network standard or the second network standard to be transmitted can be scheduled to any target carrier, thereby realizing spectrum sharing. Therefore, as long as there is an unblocked cell corresponding to a target carrier participating in spectrum sharing, the communication service can be scheduled to the target carrier with the unblocked cell, and thus continue to communicate.

[0054] For example: Figure 3 As shown, the cell corresponding to target carrier F is blocked, while the cells corresponding to target carrier G, target carrier H, and target carrier I are not blocked. However, communication service data can be scheduled to the frequency band corresponding to target carrier E. The server still needs to perform CFR on target carrier F.

[0055] In one example, if all cells corresponding to each target carrier are blocked, then CFR for each target carrier is stopped. Considering that if all cells corresponding to each target carrier are blocked, spectrum sharing fails, and communication services cannot be scheduled to any target carrier, CFR is unnecessary. The server stopping CFR for each target carrier saves CFR resources and improves spectrum sharing efficiency.

[0056] For example: Figure 3 As shown, the cells corresponding to target carrier F, target carrier G, target carrier H, and target carrier I are all blocked. At this time, communication services cannot continue, and the server stops performing CFR on each target carrier.

[0057] In one example, after selectively performing CFR on each target carrier, the server can save the carrier, cell configuration, and CFR mapping relationship.

[0058] In this embodiment, after adjusting the power of each target carrier and before scheduling the service data of the first network standard or the second network standard to be transmitted to any of the adjusted target carriers, the method further includes: activating the cells corresponding to each target carrier; obtaining the occupancy status of the cells corresponding to each target carrier; and selectively performing peak factor elimination (CFR) on each target carrier based on the occupancy status of the cells corresponding to each target carrier. In this embodiment, performing CFR on each target carrier can eliminate abnormal signals with excessively large peak values, improving communication quality and comfort. Selectively performing CFR on each target carrier allows for more targeted CFR, effectively saving CFR resources.

[0059] In one embodiment, after activating the cells corresponding to each target carrier, the server can also perform digital pre-distortion (DPD) on each target carrier. Performing DPD on each target carrier can effectively reduce the interference caused by the nonlinear distortion of the power amplifier on the signal, thereby improving the performance of the communication system.

[0060] In a practical implementation, the server can call the Digital Signal Processing (DSP) unit of the RF combiner module to perform DPD on each target carrier.

[0061] In one embodiment, before segmenting carriers with overlapping spectra based on the results of spectrum overlap identification, the server can also stop performing DPD and CFR on each carrier and clear the DPD table, thereby shutting down the cell corresponding to each carrier. Cell establishment generally causes fluctuations in total power, so stopping DPD and CFR and clearing the DPD table before cell activation can effectively avoid the impact on communication performance caused by fluctuations in total power.

[0062] Another embodiment of this application relates to an electronic device, such as... Figure 8 As shown, it includes: at least one processor 401; and a memory 402 communicatively connected to the at least one processor 401; wherein the memory 402 stores instructions executable by the at least one processor 401, the instructions being executed by the at least one processor 401 to enable the at least one processor 401 to perform the spectrum sharing methods in the above embodiments.

[0063] The memory and processor are connected via a bus, which can include any number of interconnecting buses and bridges, connecting various circuits of one or more processors and memories. The bus can also connect various other circuits, such as peripheral devices, voltage regulators, and power management circuits, which are well known in the art and will not be described further herein. The bus interface provides an interface between the bus and the transceiver. The transceiver can be a single element or multiple elements, such as multiple receivers and transmitters, providing a unit for communicating with various other devices over a transmission medium. Data processed by the processor is transmitted over the wireless medium via an antenna, which further receives data and transmits it to the processor.

[0064] The processor manages the bus and general processing, and also provides various functions, including timing, peripheral interfaces, voltage regulation, power management, and other control functions. Memory is used to store data used by the processor during operation.
