[0002] At present, the main commercial technology of mobile communications is transitioning from 4G to 5G. Since the 5G NR network adopts medium-, low-frequency and high-frequency millimeter wave bands, its spatial attenuation and dielectric loss are relatively large. Compared with 4G, the method of outdoor coverage indoors will be more difficult. It is necessary to build a dedicated indoor network indoors to solve the indoor coverage blind spots and provide better 5G services.

Pico base stations are divided into integrated pico base stations and extended pico base stations. Among them, distributed pico base stations use digital technology and are based on optical fiber or network cables to carry wireless signal transmission and distribution.

[0032] Figure 1 The application scenario diagram of the control method according to the embodiment of the present disclosure is schematically shown.

[0033] like Figure 1 As shown, the purpose of implementing the application scenario 100 according to this embodiment is to realize power supply and transmission of a distributed pico base station system.

[0034] In application scenario 100, the distributed pico base station system includes a hub (rHUB) 110, pico base stations (pRRU) 120, 130. The hub 110 can be used as a multi-port repeater to regenerate, shape and amplify the signal sent by the baseband unit module (BBU) of the main device in the forward signal, and shape and amplify the signal sent by the radio frequency remote unit module in the reverse channel, thereby successively expanding the transmission distance of the network, and at the same time concentrating all radio frequency remote unit modules on a device centered on the hub unit module. The hub 110 can process the forward and reverse signals in parallel. When the hub 110 is the central device, a failure in a line in the network does not affect the operation of other lines. The hub 110 may include, for example, MUSUMI series switches, TP-LINK series switches, SCALANCE series switches, etc.

[0035] One end of the pico base stations 120 and 130 can be connected to the hub 110 module via a network cable for signal transmission, and the other end can be connected to the transceiver antenna to transmit 5G signals.

[0036] In the related art, independent and dedicated power supply + transmission lines (generally composite cables, Category 6e network cables, etc.) are used between the pico base stations 120 and 130 of the distributed pico base station system and the hub 110. Each pico base station requires independent power supply from the hub 110, and each pico base station independently transmits data to the hub 110. The distances between different pico base stations and the hub 110 may vary. For example, the distance from the pico base station 120 to the hub 110 may be 150m, the distance from the pico base station 130 to the hub 110 may be 175m, and the distance between the pico base station 120 and the pico base station 130 may be 25m. The use of this power supply + transmission method will result in a large amount of cable consumption and high cost for the lines, complex construction and large engineering workload during the equipment installation and construction process, and the need to replace the entire line in the event of a line failure in the later stage, which is difficult and costly to maintain.

[0037] In view of this, the present disclosure provides a control method and a distributed pico base station system for at least partially solving the above problems.

[0038] Understandably, Figure 1 The number and type of hubs and pico base stations in the embodiment are only for illustration purposes. Any number and type of hubs and pico base stations may be provided according to implementation requirements.

[0039] The following will be based on Figure 1 The scene described by Figure 2~Figure 4 The control method of the disclosed embodiment is described in detail.

[0040] Figure 2 The flowchart of the control method according to the first embodiment of the present disclosure is schematically shown.

[0041] like Figure 2 As shown, the control method 200 of this embodiment may include S210 to S230, for example.

[0042] In S210, external power supply function and data receiving function are configured for the first-level pico base station to the N-1th level pico base station, each level of pico base station includes at least one pico base station, and N is an integer greater than or equal to 2.

[0043] In this embodiment, configuring the external power supply function for the first-level pico base station to the N-1th-level pico base station can be understood as configuring the pico base station so that the pico base station can power external devices (such as other pico base stations).

[0044] Configuring the data receiving function for the first-level pico base stations to the N-1th-level pico base stations can be understood as configuring the pico base stations so that the pico base stations can not only send data but also receive data.

[0045] The levels of the pico base stations can be divided according to preset indicators, such as distance, area, etc. Each level of pico base stations includes at least one pico base station, which can be understood as determining one pico base station as one level, or determining multiple pico base stations as the same level.

[0046] In operation S220, the first-level pico base station is powered by the power supply of the hub, and the next-level pico base station is powered by the upper-level pico base station.

[0047] In this embodiment, the hub can be configured with a power supply, which can meet the power demand for its own work and can also power the pico base station. For example, the hub can power the first-level pico base station, so that the first-level pico base station works. The first-level pico base station can transmit the power transmitted by the hub to the second-level pico base station on the premise of ensuring its normal work. The second-level pico base station can transmit the power transmitted by the hub to the third-level pico base station on the premise of ensuring its normal work, and so on.

[0048] In operation S230, delay synchronization is performed on data transmitted by each level of pico base stations. After the delay synchronization, the data received by the next level of pico base station is transmitted to the previous level of pico base station. The data after delay synchronization is centrally transmitted to the hub through the first level of pico base station.

[0049] In this embodiment, the delay synchronization of data transmission of each level of pico base station can be understood as each pico base station transmitting data based on a unified reference clock. The N-1 level pico base station can receive data from the N-level pico base station, and uniformly transmit its own data and the data of the N-level pico base station to the N-2 level pico base station; the N-2 level pico base station can receive the N-1 level data and the N-level data sent by the N-1 level pico base station, and uniformly transmit its own data, the N-1 level data and the N-level data to the N-2 level pico base station, and so on, the first level pico base station receives data from the second level pico base station to the N-level pico base station, and uniformly transmits its own data, the second level pico base station data to the N-level pico base station data to the hub.

[0050] According to the embodiments of the present disclosure, due to the limitations of the pico base station's power consumption, size, safety, etc., it is difficult to configure an independent power supply for the pico base station itself, and the traditional pico base station only has a data sending function. Through the control method of the embodiments of the present disclosure, an external power supply function is configured for each level of pico base stations, and the first-level pico base station supplies electricity to the next-level pico base station. Through this cascade power supply method, the cost of supporting auxiliary materials for the pico base station can be reduced, the construction difficulty can be reduced, the construction cost can be reduced, and when subsequent lines fail, maintenance is more convenient and cost-effective. The data receiving function is configured for each level of pico base stations, and the data received by the next-level pico base station is transmitted to the upper-level pico base station. The data after delay synchronization is centrally transmitted to the hub through the first-level pico base station, and the data of the pico base stations at all levels are merged and sent to the hub in a unified manner, thereby avoiding mutual interference between the data of the pico base stations at all levels.

[0051] Based on the above embodiments, the method for configuring an external power supply function for the pico base station in the control method of this embodiment may include: configuring a power supply output port for the first-level pico base station to the N-1-level pico base station, so that the upper-level pico base station can supply power to the next-level pico base station through the power supply output port.

[0052] Figure 3 The figure schematically shows the connection diagram between the hub and the pico base stations at various levels according to the second embodiment of the present disclosure.

[0053] like Figure 3 As shown, the hub 310 may be configured with a first power supply output port 311, the pico base station 320 may be configured with a first power supply receiving port 321 and a second power supply output port 322, and the pico base station 330 may be configured with a second power supply receiving port 331. The first power supply output port 311 and the first power supply receiving port 321 may be connected by a cable, and the second power supply output port 322 and the second power supply receiving port 331 may be connected by a cable.

[0054] Types of the first power supply output port 311 , the first power receiving port 321 , and the second power supply output port 322 may be USB interfaces, DC power interfaces, AC power sockets, and the like.

[0055] When the power supply of the hub 310 is turned on, the power can be transmitted to the first power receiving port 321 through a cable based on the first power output port 311, and the pico base station 320 can work based on the power received by the first power receiving port 321. The power can be transmitted to the second power receiving port 331 through a cable based on the second power output port 322, and the pico base station 330 can work based on the power received by the second power receiving port 331, thus realizing cascade power supply.

[0056] Through the control method of the embodiment of the present disclosure, the physical port for external power supply is directly configured for the pico base station. The configuration method is simple, and the power supply connection between the pico base stations at all levels is also simple and easy to operate.

[0057] Based on the above embodiments, the method for configuring an external power supply function for a pico base station in the control method of this embodiment may also include: integrating a chip in the first-level pico base station to the N-1-level pico base station, and the chip is configured to amplify at least one of the current, voltage or power corresponding to the output of the previous-level pico base station to meet the power supply requirements of the next-level pico base station.

[0058] Figure 4 The figure schematically shows the connection diagram between the hub and the pico base stations at various levels according to the third embodiment of the present disclosure.

[0059] like Figure 4 As shown, the hub 410 may be configured with a first power supply output port 411, the pico base station 420 may be configured with a first power supply receiving port 421 and a second power supply output port 422, and the pico base station 430 may be configured with a second power supply receiving port 431. The first power supply output port 411 and the first power supply receiving port 421 may be connected via a cable, and the second power supply output port 422 and the second power supply receiving port 431 may be connected via a cable. The pico base station 420 may integrate a first chip 423.

[0060] Types of the first power supply output port 411 , the first power receiving port 421 , and the second power supply output port 422 may be USB interfaces, DC power interfaces, AC power sockets, and the like.

[0061] When the power supply of the hub 410 is turned on, the power can be transmitted to the first power receiving port 421 through a cable based on the first power output port 411. At this time, the pico base station 420 can work based on the power received by the first power receiving port 421. At least one of the current, voltage or power corresponding to the power received by the first power receiving port 421 can be amplified based on the first chip 423, and then the amplified power can be transmitted to the second power receiving port 431 through a cable based on the second power output port 422. At this time, the pico base station 430 can work based on the power received by the second power receiving port 431, realizing cascade power supply.

[0062] In a possible implementation, the first chip may use a linear regulator (LDO): an input voltage may be increased to a specific output voltage.

[0063] In another possible implementation, the first chip may adopt a switching power supply (Buck / Boost Converter): a high-efficiency power management chip for voltage conversion, wherein a Buck converter is used to reduce the voltage, and a Boost converter is used to increase the voltage.

[0064] In another possible implementation, the first chip may use an operational amplifier (Op-Amp): used for amplifying analog signals, the operational amplifier may be used for a variety of applications, including signal processing and sensor signal amplification.

[0065] In another possible implementation, the first chip may use a power amplifier (Power Amplifier): used for audio, radio frequency and other applications requiring high-power signals, and capable of effectively amplifying the signal to the required output power.

[0066] In another possible implementation, the first chip may adopt a current driver (Current Driver): a chip used to drive a load, which can provide a relatively large current output and is suitable for applications such as LED driving or motor control.

[0067] When there are many levels of pico base stations and the distance between the pico base stations and the hub is getting farther and farther, due to the voltage drop in long-distance transmission, the power received by the upper-level pico base station may only meet its own power supply needs. Therefore, when there are many levels, considering the power supply capacity of the hub and the length of the line, it is also possible to integrate chips such as voltage transformation and power amplification in the pico base stations to boost the voltage, amplify the current or amplify the power before supplying power to the next-level pico base station. This can better meet the power supply needs of pico base stations at all levels and ensure the normal operation of pico base stations at all levels.

[0068] Based on the above embodiments, configuring a data receiving function for the first-level pico base station to the N-1-level pico base station may include: configuring a data receiving port for the first-level pico base station to the N-1-level pico base station, so that the upper-level pico base station receives the data sent by the lower-level pico base station through the data receiving port.

[0069] Continue reading Figure 4 The hub 410 may be configured with a first data receiving port 412, the pico base station 420 may be configured with a first data sending port 424 and a second data receiving port 425, and the pico base station 430 may be configured with a second data sending port 432. The first data receiving port 412 and the first data sending port 424 may be connected via a network cable, and the second data receiving port 425 and the second data sending port 432 may be connected via a network cable.

[0070] The pico base station 430 transmits data to the second data receiving port 425 via a network cable based on the second data sending port 432, and the pico base station 420 transmits its own data and the data received from the pico base station 430 to the first data receiving port 412 based on the first data sending port 424. At this point, the hub 410 synchronously obtains the data of the pico base station 420 and the pico base station 430.

[0071] Through the control method of the embodiment of the present invention, the physical port for data transmission is directly configured for the pico base station. The configuration method is simple, and the data transmission connection between the pico base stations at all levels is also simple and easy to operate.

[0072] It should be noted that the above-mentioned cables and network cables can adopt composite cables to realize the functions of power supply and data transmission at the same time, and the corresponding power supply port and data transmission port can be integrated into one port to realize the functions of power supply and data transmission at the same time.

[0073] It should be noted that the corresponding auxiliary materials can be selected according to the amount of data transmitted between the hub and the pico base stations at various levels.

[0074] Based on the above embodiments, in the control method of this embodiment, the delay synchronization of data transmitted by each level of pico base stations may include: sending time synchronization information to the pico base station of the next level through the pico base station of the previous level, so that the pico base station of the next level calibrates the local clock according to the time information.

[0075] In a distributed pico base station system, the accuracy of time calibration between pico base stations at all levels directly affects the accuracy of network synchronization and signal transmission, so the synchronous transmission of data is particularly important.

[0076] In this embodiment, the upper-level pico base station may be used to perform time calibration on the lower-level pico base station to synchronize the time.

[0077] In a possible implementation, the upper-level pico base station may select a reliable time source, such as a GPS signal or other time synchronization signal, to ensure that its own time reference is accurate.

[0078] The upper-level pico base station can send time information to the lower-level pico base stations through time synchronization protocols (such as PTP, Precision Time Protocol). These protocols can ensure that the lower-level pico base stations can accurately receive and calibrate their local clocks.

[0079] The lower-level pico base station can calculate the time deviation between it and the upper-level pico base station based on the received time information. This deviation can be compensated to ensure the time consistency between the upper and lower pico base stations.

[0080] The lower-level pico base station can adjust its local clock according to the calculated deviation. The adjustment can be achieved by fine-tuning the clock frequency or directly correcting the time value.

[0081] In another possible implementation, during system operation, the upper-level pico base station can periodically send time information to cope with time drift caused by environmental changes, equipment aging, etc. The lower-level pico base station also needs to continuously monitor the synchronization status of its clock with the upper-level pico base station.

[0082] In another possible implementation, a feedback mechanism may be established so that the lower-level pico base station can feed back the synchronization status to the upper-level pico base station, thereby making necessary adjustments.

[0083] Through the control method of the disclosed embodiment, the upper-level pico base station can effectively calibrate the time of the lower-level pico base station to ensure the stability and communication quality of the entire network. At the same time, the time synchronization tasks of the pico base stations at all levels are shared to the upper-level pico base stations of the pico base stations at all levels, which can reasonably distribute the time synchronization tasks and reduce the pressure of unified time synchronization.

[0084] On the basis of the above-mentioned embodiments, in the control method of this embodiment, delay synchronization is performed on data transmitted by each level of pico base stations, and it may also include: the first level pico base station performs delay synchronization on the data received from the pico base stations at each level.

[0085] In a possible implementation, the first-level pico base station can select a reliable time source, and the first-level pico base station can send time information to the lower-level pico base stations through a time synchronization protocol. The lower-level pico base station can calculate the time deviation between the lower-level pico base station and the first-level pico base station based on the received time information. The lower-level pico base station can adjust its local clock based on the calculated deviation, and the adjustment can be achieved by fine-tuning the clock frequency or directly correcting the time value.

[0086] In the process of using the upper-level pico base station to synchronize the time of the next pico base station, the time reference for calculating the time deviation is the time reference of the pico base station at the upper level, and there may be errors between the time references of the pico base stations at the upper level. Through the control method of the embodiment of the present invention, the first-level pico base station is used to uniformly send time information to synchronize the pico base stations at all levels, which can avoid the problem of errors in the reference for calculating the time deviation and inaccurate time synchronization in the process of the upper-level pico base station performing time synchronization on the next pico base station, thereby improving the accuracy of time synchronization.

[0087] Based on the above embodiment, the control method of this embodiment may further include:

[0088] Before configuring external power supply function and delay processing function for the first-level pico base station to the N-1-level pico base station, multiple pico base stations are determined as N-level pico base stations according to the transmission distance between the multiple pico base stations and the hub, wherein the transmission distance between the pico base station and the hub gradually increases from the first-level pico base station to the N-level pico base station.

[0089] For example, the distance from one pico base station to the hub is 150m, and the distance from another pico base station to the hub is 175m. The pico base station with a distance of 150m to the hub can be determined as the first-level pico base station, and the pico base station with a distance of 175m to the hub can be determined as the second-level pico base station.

[0090] For another example, the first area is closer to the hub and the second area is farther from the hub. Multiple pico base stations in the first area can be determined as first-level pico base stations, and multiple pico base stations in the second area can be determined as second-level pico base stations.

[0091] Through the control method of the embodiment of the present invention, based on the transmission distance between each pico base station and the hub, the level of the pico base station can be determined more reasonably, the total line of the power supply level transmission can be shortened as much as possible, a better power supply method and data transmission method can be achieved, and costs can be reduced.

[0092] Based on the above embodiment, the transmission distance between the hub and the first-level pico base station can be greater than the transmission distance between the upper-level pico base station and the lower-level pico base station.

[0093] In actual application scenarios, there are many possibilities for the distance between the hub and the pico base station, and the distance between the pico base stations. The distance between the pico base stations may be greater than the distance between the hub and the pico base station. Since the hub is the initial power supply, the distance of power transmission is relatively long. The power required for the normal operation of each level of pico base stations comes from the power supply of the hub, and there is no power supply itself. If the distance between the upper-level pico base station and the lower-level pico base station is determined to be too large, even if the integrated chip in the upper-level pico base station is boosted, it may not meet the power supply requirements of the lower-level pico base station. Therefore, the distance between the upper-level pico base station and the lower-level pico base station is likely to be small, and the transmission distance between the hub and the first-level pico base station can be greater than the transmission distance between the upper-level pico base station and the lower-level pico base station, so as to ensure the normal operation of the pico base stations at all levels.

[0094] Based on the above control method, the present disclosure also provides a distributed pico base station system. Figure 5 The distributed pico base station system is described in detail.

[0095] Figure 5 The structure diagram of a distributed pico base station system according to an embodiment of the present disclosure is schematically shown.

[0096] like Figure 5 As shown, the distributed pico base station system 500 may include a hub 510 and a plurality of pico base stations 520 .

[0097] The plurality of pico base stations 520 are divided into N levels, and the first level pico base station to the N-1 level pico base station are configured with a delay processing function and an external power supply function, where N is an integer greater than or equal to 2. The first level pico base station is powered by the power supply of the hub 510, and the next level pico base station is powered by the upper level pico base station;

[0098] The data received by the next-level pico base station is transmitted to the previous-level pico base station. The received data is delayed synchronized based on the delay processing function of each level of pico base stations, and the delay-synchronized data is centrally transmitted to the hub 510 through the first-level pico base station.

[0099] It should be noted that the distributed pico base station system part in the embodiment of the present disclosure corresponds to the control method part in the embodiment of the present disclosure, and their specific implementation details are also the same, which will not be repeated here.

In one embodiment, the power supply module 620 can be used to execute S220 described above, which will not be repeated here.

[0105] The synchronization module 630 is used to perform delay synchronization on the data transmitted by the pico base stations at each level, transmit the data received by the next-level pico base station to the previous-level pico base station after the delay synchronization, and transmit the data after the delay synchronization to the hub through the first-level pico base station. In one embodiment, the synchronization module 630 can be used to execute S230 described above, which will not be repeated here.
