These drawings and textual descriptions are not intended to limit the scope of the concept of this application in any way, but to illustrate the concept of this application to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0055] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with this application. On the contrary, they are merely examples of devices and methods consistent with some aspects of this application as detailed in the appended claims.

[0056] In practical applications, an FDD base station can only perform uplink frequency scanning to obtain the uplink frequency scanning result, and cannot obtain the downlink frequency scanning result. Since the occupied bandwidth of the uplink frequency band and the occupied bandwidth of the downlink frequency segment in the FDD base station are inconsistent, if cell establishment is only based on the uplink frequency scanning result, it will cause serious interference in the downlink frequency band and poor cell communication quality, resulting in the inability to carry out terminal services.

[0057] The cell establishment method provided by this application aims to solve the above technical problems in the prior art. Specifically, by enabling the base station to obtain the uplink and downlink frequency scanning results respectively, and then selecting the optimal frequency band to establish a cell according to the uplink and downlink frequency scanning results, the communication quality of the established cell can be improved.

[0058] Figure 1 An application scenario diagram of the cell establishment method provided by this application. For ease of understanding, the following combination of Figure 1 is used to describe the application scenario applicable to the embodiments of this application. Refer to Figure 1, an FDD base station includes a building baseband unit (BBU) and a remote radio unit (RRU). Specifically, the BBU generates a frequency scanning instruction and sends the frequency scanning instruction to the RRU; the RRU performs uplink frequency scanning processing based on the frequency scanning instruction, switches filters after obtaining the uplink frequency scanning result, and performs downlink frequency scanning processing based on the switched filter, thereby obtaining a downlink frequency scanning result, and sends the uplink frequency scanning result and the downlink frequency scanning result to the BBU; the BBU obtains the cell bandwidth threshold, and respectively scans and traverses in the uplink frequency scanning result and the downlink frequency scanning result based on the cell bandwidth threshold to obtain a target bandwidth that meets the preset requirements, and then performs a cell establishment operation based on the target bandwidth to obtain a cell establishment result.

[0059] The following uses specific embodiments to elaborate in detail on the technical solution of this application and how the technical solution of this application solves the above technical problems. These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0060] Figure 2 It is a schematic flowchart of a cell establishment method provided by an embodiment of this application. The method in this embodiment can be implemented through software, hardware, or a combination of software and hardware. As Figure 2 shown, the method includes the following steps.

[0061] S210: Generate a frequency scanning instruction, and respectively perform uplink frequency scanning and downlink frequency scanning processing based on the frequency scanning instruction to obtain an uplink frequency scanning result and a downlink frequency scanning result.

[0062] In the embodiment of this application, the frequency scanning processing can be understood as scanning and querying the occupied bandwidth within a preset frequency band to perform subsequent service processing based on the scanning result, such as performing service processing such as cell establishment.

[0063] In practical applications, a base station includes one or more baseband units and one or more remote radio units to achieve signal reception and transmission. In order to make the communication quality of the subsequently established cell better, that is, the devices within the established cell can successfully send signals and receive signals, uplink frequency scanning processing and downlink frequency scanning processing can be respectively performed during frequency scanning processing, and then the target bandwidth for cell establishment is determined based on the uplink frequency scanning result and the downlink frequency scanning result respectively, and then cell establishment is performed.

[0064] On this basis, the complete frequency sweep processing process can be implemented based on a baseband unit (BBU) and a remote radio unit (RRU). Specifically, the frequency sweep processing process can include: the BBU generates a frequency sweep instruction and sends the frequency sweep instruction to the RRU; the RRU performs an uplink frequency sweep processing within a first frequency band range based on the frequency sweep instruction, and performs a downlink frequency sweep processing within a second frequency band range based on the frequency sweep instruction, respectively obtaining an uplink frequency sweep result corresponding to the first frequency band range and a downlink frequency sweep result corresponding to the second frequency band range.

[0065] In order to obtain the uplink frequency sweep result and the downlink frequency sweep result in this application, in the embodiments of this application, the BBU and the RRU in the base station are used for frequency sweep processing. The specific processing process can include: after the BBU is powered on, it generates a frequency sweep instruction based on a preset starting frequency range, frequency sweep bandwidth, preset scanning time, scanning frequency points, etc., and sends the frequency sweep instruction to the RRU to notify the RRU to perform frequency sweep processing based on the above conditions.

[0066] Furthermore, the RRU can first perform an uplink frequency sweep according to the frequency sweep instruction notification from the BBU. In the case of obtaining the uplink frequency sweep result, it triggers the downlink frequency sweep processing to obtain the downlink frequency sweep result, and after the frequency sweep is completed, it reports the uplink and downlink frequency sweep results to the BBU. Optionally, the RRU can send the uplink frequency sweep result to the BBU immediately when it obtains the uplink frequency sweep result, and send the downlink frequency sweep result to the BBU when it obtains the downlink frequency sweep result; optionally, it can also send the uplink frequency sweep result and the downlink frequency sweep result to the BBU together when it obtains the downlink frequency sweep result.

[0067] In the prior art, since the FDD base station transmits and receives on different frequency bands, that is, limited by the radio frequency channel limitation, only the uplink frequency sweep can be performed; in order to obtain the downlink frequency sweep result, in the embodiments of this application, after the uplink frequency sweep processing is performed, the receiving channel connected to the filter of the first frequency band range is switched to be filtered and connected to the second frequency band range, so as to implement the downlink frequency sweep and obtain the downlink frequency sweep result.

[0068] Optionally, the method for implementing simultaneous uplink and downlink frequency sweep by switching the connection of the filter specifically includes: controlling the receiving channel to be connected to the first filter, and receiving the frequency sweep data within the first frequency band range based on the first filter as the uplink frequency sweep result; when receiving the uplink frequency sweep result, controlling the receiving channel to be connected to the second filter, and receiving the frequency sweep data within the second frequency band range based on the second filter as the downlink frequency sweep result.

[0069] In practical applications, when the RUU performs frequency scanning processing, it controls the RX channel to be connected to the RX filter to implement uplink frequency scanning processing; further, in the case of obtaining the uplink frequency scanning result after the uplink frequency scanning is completed, it controls the RX channel to be connected to the TX filter, and then implements downlink frequency scanning processing to obtain the downlink frequency scanning result. It should be noted that in practical applications, RX is the receiving channel. By connecting it to the RX filter in the uplink channel, it can receive the frequency band occupancy data in the uplink channel, that is, obtain the uplink frequency scanning result; further, by controlling it to be connected to the TX filter in the downlink channel, it can receive the frequency band occupancy data in the downlink channel and obtain the downlink frequency scanning result; based on the above solution, uplink frequency scanning and downlink frequency scanning can be respectively performed in the FDD base station, and complete uplink and downlink frequency scanning results can be obtained, so as to realize the subsequent cell establishment.

[0070] It should be noted that in practical applications, the RX channel is the receiving channel and needs to be connected to the corresponding RX filter for service processing, and the TX channel is the transmitting channel and needs to be connected to the corresponding TX filter for service processing; since in the above implementation, in order to enable the FDD base station to perform downlink frequency scanning, the RX channel is connected to the TX filter to receive the occupancy of the downlink frequency band. After the frequency scanning processing is completed, in order to implement the original service processing, the technical solution of this application further includes: controlling the receiving channel to be connected to the first filter and controlling the transmitting channel to be connected to the second filter. In other words, the RRU needs to connect the RX channel to the RRU RX filter and the TX channel to the RRU TX filter to complete the original service processing.

[0071] S220. Obtain a preset cell bandwidth threshold, determine a target bandwidth based on the cell bandwidth threshold, the uplink frequency scanning result, and the downlink frequency scanning result, and perform cell establishment based on the target bandwidth to obtain an establishment result.

[0072] In practical applications, since only the uplink frequency scanning result is used for cell establishment in the prior art, the communication quality of the obtained cell is poor. To solve the above technical problem, in the technical solution provided by the embodiment of this application, after obtaining the uplink frequency scanning result and the downlink frequency scanning result based on the above implementation, the unoccupied target bandwidth is determined based on the uplink frequency scanning result and the downlink frequency scanning result, so as to improve the communication quality of the established cell.

[0073] In the embodiment of this application, the method for determining the target bandwidth may specifically include: respectively scanning and traversing the uplink frequency scanning result and the downlink frequency scanning result based on the cell bandwidth threshold to obtain a target bandwidth that meets the preset scanning condition.

[0074] Specifically, after determining the cell bandwidth threshold, perform a scanning traversal in the uplink scanning result and the downlink scanning result respectively based on the cell bandwidth threshold. Based on the preset scanning conditions, obtain the unoccupied uplink bandwidth in the uplink scanning result and the unoccupied downlink bandwidth in the downlink scanning result respectively, and then determine the uplink bandwidth and the downlink bandwidth as the target bandwidth for cell establishment. On the basis of the above implementation, if the target bandwidth is not determined in the uplink scanning result and the downlink scanning result based on the cell bandwidth threshold, the cell bandwidth threshold can be reduced, and then traverse again based on the modified threshold until the target bandwidth is determined.

[0075] It should be noted that the preset scanning condition in this application is to simultaneously determine whether the bandwidth occupancy of the uplink and downlink frequency bands meets certain conditions; in practical applications, this condition can be set to meet a series of principles such as the interference rise threshold or the optimal spectrum efficiency within the working bandwidth. Of course, the preset scanning condition can also be set to other conditions according to the actual situation, and this application does not make specific limitations on this.

[0076] It should also be noted that before determining the target bandwidth in this application, it is also necessary to pre-determine the cell bandwidth threshold. Optionally, the process of determining the cell bandwidth threshold can be: obtain the communication system of the base station, and determine the cell bandwidth threshold corresponding to the communication system based on the preset communication rules.

[0077] Exemplarily, the BBU determines the maximum cell bandwidth supported by the relevant system according to the current system, such as the 4G or 5G system, and determines this maximum cell bandwidth as the cell bandwidth threshold.

[0078] Further, after determining the target bandwidth, the technical solution of this application further includes: performing cell establishment based on the target bandwidth to obtain an establishment result. Specifically, the establishment process can include: receiving the cell search operation of the user equipment based on the target bandwidth, and performing cell establishment based on the search operation to obtain an establishment result.

[0079] Specifically, after the BBU obtains the target bandwidth, it performs cell establishment, and uses the user equipment (UE) to perform cell search and then successfully access the FDD base station for uplink and downlink services, thereby realizing cell establishment.

[0080] In the above technical solution, by switching the signal receiving channels in the base station to filters of different frequency bands respectively, the uplink scanning result and the downlink scanning result can be received respectively, and then according to the uplink and downlink scanning results, the optimal frequency band is selected to establish a cell, so as to improve the communication quality of the established cell.

[0081] On the basis of the above implementation, this application also provides a preferred implementation. Figure 3Schematic diagram of the cell establishment process provided by this application in an exemplary alternative embodiment. Refer to Figure 3 , the exemplary alternative embodiment includes the following steps:

[0082] 1. Power on the BBU base station;

[0083] 2. The BBU notifies the RRU to start frequency scanning, and the notification message includes the starting frequency range, scanning bandwidth, and scanning time;

[0084] 3. The RRU connects the RX channel to the RX filter and performs uplink frequency scanning according to the requirements of the BBU notification message. After the frequency scanning is completed, the uplink frequency scanning result is reported to the BBU;

[0085] 4. After step 3 is completed, the RRU switches the RX channel to the TX filter and performs downlink frequency scanning according to the requirements of the BBU notification message. After the frequency scanning is completed, the downlink frequency scanning result is reported to the BBU;

[0086] 5. The RRU RX channel is connected to the RRU RX filter, and the TX channel is connected to the RRU TX filter;

[0087] 6. The BBU receives the uplink and downlink frequency scanning results of the RRU;

[0088] 7. The BBU traverses from the maximum cell bandwidth supported by the relevant system, such as 4G or 5G system, and at the same time determines whether the interference between the uplink and downlink frequency bands meets certain conditions. This condition can be set to meet a series of principles such as the interference rise threshold or the optimal spectral efficiency within the working bandwidth;

[0089] 8. The BBU obtains the bandwidth and frequency points that meet the requirements for the uplink and downlink;

[0090] 9. The BBU establishes a cell according to the results obtained in step 8, and the UE successfully accesses the FDD base station for uplink and downlink services after cell search.
