[0041] The present application provides a 5G base station device that can support 4G communication and / or 5G communication. The communication capability of the 5G base station device can be flexibly configured according to the usage of 4G communication and / or 5G communication by users within the coverage area of ​​the base station, thereby ensuring a smooth transition from 4G communication to 5G communication, and thus improving user satisfaction.

[0042] Example 1

[0043] An embodiment of the present application, such as Figure 1 As shown, a 5G communication circuit is proposed, which includes a 5G baseband control module 11, a 5G communication module 12, a 4G communication module 15, a radio frequency module 13 and an antenna module 14.

[0044] The first control interface of the 5G baseband control module 11 is connected to the communication interface of the 5G communication module 12, the 5G RF signal sending interface and the 5G RF signal receiving interface of the 5G communication module 12 are connected to the RF module 13, and the RF module 13 is connected to the antenna module 14.

[0045] The second control interface of the 5G baseband control module 11 is connected to the communication interface of the 4G communication module 15 , and the 4G RF signal sending interface and the 4G RF signal receiving interface of the 4G communication module 15 are connected to the 5G communication module 12 .

[0046] Considering that the spectrum of 4G signal and 5G signal are similar, for example, the spectrum range of band41 (4G) 2496-2690MHZ and the spectrum range of N41 (5G) 2515-2675MHZ have overlapping parts; the spectrum range of Band42 (4G) 3400-3600MHZ and the spectrum range of N78 (5G) 3400-3600MHZ have overlapping parts, therefore, the same RF module 13 can meet both 4G communication and 5G communication.

[0047] It is understandable that the 5G and / or 4G operators can set the 5G communication circuit to provide only 5G communication or provide both 4G and 5G communication according to the actual scenario. Exemplarily, the 5G and / or 4G operators can switch the 5G communication circuit to provide only 5G communication or provide both 4G and 5G communication through program commands in the operation center; the 5G and / or 4G operators can also pre-burn the automatic control program to the 5G baseband control module 11 to automatically control the 5G communication circuit to work in the 5G communication state for a period of time and in the 4G+5G communication state for a period of time, so as to realize the alternating operation of the 5G communication state and the 4G+5G communication state.

[0048] In the 5G communication circuit disclosed in this embodiment, the 4G communication module 15 can not only receive the RF signal sent by the RF module 13 through the 5G communication module 12, but also send the 4G RF signal to the RF module 13 through the 5G communication module 12. Furthermore, while ensuring that the 5G communication module 12 can receive and send 5G RF signals, the 4G communication module 15 can receive and send 4G RF signals, thereby realizing the simultaneous reception and transmission of 4G RF signals and 5G RF signals.

[0049] Example 2

[0050] An embodiment of the present application, see Figure 2The 5G communication module 12 includes a 5G RF transceiver unit, N analog-to-digital conversion units, N digital-to-analog conversion units and 2M RF switches, where N is an even number and M<N.

[0051] The communication interface of the 5G RF transceiver unit serves as the communication interface of the 5G communication module 12, and each digital signal sending port of the 5G RF transceiver unit is connected to the digital signal receiving port of the corresponding digital-to-analog conversion unit.

[0052] The analog signal sending ports of the M digital-to-analog conversion units are connected to the analog signal receiving ports of the corresponding RF switches, and the analog signal output ports of the RF switches corresponding to the M digital-to-analog conversion units serve as 5G RF signal sending interfaces.

[0053] The analog signal sending ports of the NM digital-to-analog conversion units serve as 5G RF signal sending interfaces.

[0054] Each digital signal receiving port of the 5G RF transceiver unit is connected to the digital signal sending port of the corresponding analog-to-digital conversion unit.

[0055] The analog signal receiving ports of the M analog-to-digital conversion units are connected to the analog signal output ports of the corresponding RF switches, and the analog signal receiving ports of the RF switches corresponding to the M analog-to-digital conversion units serve as 5G RF signal receiving interfaces.

[0056] The analog signal receiving ports of the NM analog-to-digital conversion units serve as 5G RF signal receiving interfaces.

[0057] For further information, see Figure 2 The 4G communication module 15 includes a 4G baseband control unit and a 4G radio frequency transceiver unit.

[0058] The communication interface of the 4G baseband control unit serves as the communication interface of the 4G communication module 15, and the control port of the 4G baseband control unit is connected to the control signal receiving port of the 4G radio frequency transceiver unit.

[0059] The 4G RF signal sending interface of the 4G RF transceiver unit serves as the 4G RF signal sending interface of the 4G communication module 15 , and the 4G RF signal receiving interface of the 4G RF transceiver unit serves as the 4G RF signal receiving interface of the 4G communication module 15 .

[0060] For further information, see Figure 2 The RF module 13 includes N TX signal amplifying units, N RX signal amplifying units and N signal switching units.

[0061] The 5G RF signal receiving interfaces of the N TX signal amplifying units are connected to the corresponding 5G RF signal sending interfaces, and the 5G RF signal output interfaces of the N TX signal amplifying units are connected to the first ends of the corresponding signal switching units.

[0062] The 5G RF signal sending interfaces of the N RX signal amplifying units are connected to the corresponding 5G RF signal receiving interfaces, and the 5G RF signal input interfaces of the N RX signal amplifying units are connected to the second ends of the corresponding signal switching units.

[0063] The third terminals of the N signal switching units are connected to the antenna module 14 .

[0064] It can be understood that the TX signal amplifying unit can be a power amplifier for amplifying the TX signal, that is, amplifying the 5G RF signal or 4G RF signal output by the 5G communication module 12; the RX signal amplifying unit can be a low noise amplifier for amplifying the RX signal, that is, amplifying the RF signal received from the antenna module 14.

[0065] For further information, see Figure 2 The antenna module 14 includes N antennas, and the N antennas are correspondingly connected to the third ends of the N signal switching units.

[0066] This embodiment discloses the main functional units of the 5G baseband control module 11, the 5G communication module 12, the 4G communication module 15, the radio frequency module 13 and the antenna module 14 in the 5G communication circuit and the connection relationship between the main functional units. According to the technical solution provided in this embodiment, the simultaneous reception and transmission of 4G radio frequency signals and 5G radio frequency signals can be realized quickly and conveniently.

[0067] Example 3

[0068] An embodiment of the present application, see Figure 3 Preferably, the 5G baseband control module 11 may include an LS2160 chip, the 5G communication module 12 is mainly composed of a 5G transceiver element 121 (ZU49DR chip) and a radio frequency switch group 122, the 4G baseband control unit may include an FSM9955 chip, and the 4G radio frequency transceiver unit includes two FTR8900 chips.

[0069] The LS2160 chip has communication functions and processor functions. While realizing 4G and 5G communications, it can save the switch unit and realize Ethernet communication. The LS2160 chip is connected to the 5G communication module 12 (ZU49DR) through the 10 Gigabit Ethernet communication interface (10GE), and the LS2160 chip is connected to the 4G baseband control unit (FSM9955) of the 4G communication module 15 through the Gigabit Ethernet communication interface (1GE).

[0070] Further, such as Figure 3As shown, the 5G RF transceiver function can be realized inside the 5G transceiver element 121 (ZU49DR chip), wherein DPD is used to represent the 5G RF transceiver unit, and the 5G transceiver element 121 (ZU49DR chip) has 16 14-bit digital-to-analog conversion units (ADCs) and 16 14-bit analog-to-digital conversion units (DACs) inside. The 5G transceiver element 121 (ZU49DR chip) can provide 16*16 MIMO 5G communication.

[0071] Exemplarily, the analog signal receiving ports of the analog-to-digital conversion units (ADCs) of the 0th to 11th channels of ZU49DR can receive 5G RF signals sent by the RF module 13, the analog signal sending ports of the digital-to-analog conversion units (DACs) of the 0th to 11th channels can send 5G RF signals to the RF module 13, the analog signal receiving ports of the analog-to-digital conversion units of the 12th to 15th channels are connected to the analog signal output ports of the corresponding RF switches, and the 5G RF signals sent by the RF module 13 enter the corresponding analog-to-digital conversion units (ADCs) through the corresponding RF switches to achieve 4G communication through the switching of the corresponding RF switches, and the analog signal sending ports of the digital-to-analog conversion units (DACs) of the 12th to 15th channels are connected to the analog signal receiving ports of the corresponding RF switches, and the 5G RF signals enter the RF module 13 through the corresponding RF switches to achieve 4G communication through the switching of the corresponding RF switches.

[0072] It can be understood that by controlling the switch state of each RF switch in the RF switch group 122, the 5G communication circuit can be implemented to simultaneously receive and send 5G RF signals and 4G RF signals. When the 5G communication circuit simultaneously receives and sends 5G RF signals and 4G RF signals, 12 channels of ZU49DR are used to receive and send 5G RF signals, and the remaining 4 channels of ZU49DR are used to receive and send 4G RF signals. By controlling the switch state of each RF switch, the 5G communication circuit can also be implemented to only receive and send 5G RF signals. When the 5G communication circuit only receives and sends 5G RF signals, 16 channels of ZU49DR are used to receive and send 5G RF signals. It should be understood that the 5G communication capability of the 16 channels of ZU49DR for receiving and sending 5G RF signals is better than the 5G communication capability of the 12 channels for receiving and sending 5G RF signals. Therefore, if there is no 4G communication equipment within the communication range, all 16 channels of ZU49DR can be used to receive and send 5G RF signals to improve 5G communication capabilities. If there is a 4G communication equipment within the communication range, 4 channels of ZU49DR can be used to receive and send 4G RF signals to achieve normal communication of the 4G communication equipment. It can be understood that the communication function of the 5G communication circuit can be flexibly set according to environmental requirements.

[0073] Furthermore, PA0-PA1 of the RF module 13 represents a TX signal amplification unit, and PA0-PA1 may be a power amplifier for amplifying the 5G RF signal and / or 4G RF signal output by the ZU49DR, and sending the amplified 5G RF signal and / or 4G RF signal to the antenna module 14 through the signal switching unit; LAN0-LAN1 of the RF module 13 represents an RX signal amplification unit, and LAN0-LAN1 may be a low noise amplifier for amplifying the 5G RF signal received from the antenna module 14, and sending the amplified 5G RF signal to the ZU49DR. Among them, S1-S15 represent a signal switching unit.

[0074] For further information, see Figure 4 , shows a basic structure of a 4G communication module 15, the 4G communication module 15 includes a FSM9955 chip and two FTR8900 chips, Figure 4 The connection relationship between the various pins of the FSM9955 chip and the two FTR8900 chips and the peripheral circuits (power supply circuit, clock circuit, flash memory circuit and storage circuit, etc.) related to the FSM9955 chip and the two FTR8900 chips are shown. The FTR8900 chip is connected to the LS2160 chip via the SGMII0 interface. Furthermore, the TX0 pin and TX1 pin of FTR8900#1 and the TX2 pin and TX3 pin of FTR8900#2, the output RF TX signal (4G RF signal) are switched by the RF switches (switch0, switch2, switch4, switch6), input to the TX signal amplification unit of the RF module 13, and sent to the antenna module 14 after being amplified by the TX signal amplification unit. The RX0 pin and RX1 pin of FTR8900#1 and the RX2 pin and RX3 pin of FTR8900#2 receive the RF RX signal (4G RF signal) amplified by the RX signal amplification unit of the RF module 13 through the switching of the RF switches (switch1, switch3, switch5, switch7). The FSM9955 chip is connected to the LS2160 using the SGMII interface.

[0075] For further information, see Figure 5 , shows a basic structure of a 5G communication module 12, the 5G communication module 12 includes an LS2160 chip and an LS2160 chip, the LS2160 is connected to the ZU49DR chip via a 10 Gigabit Ethernet interface (10GE), and the 5G communication module 12 also includes a power connection interface (Power Connector) and peripheral circuits related to the LS2160 chip. The LS2160 has a switching function and can realize Ethernet communication. By making full use of the performance of the LS2160 processor, the switch unit can be omitted.

[0076] According to the target function of the 5G communication circuit (simultaneously realizing 4G and 5G communications), this application selects the best chip from many types of chips with similar functions and proposes a preferred 5G communication circuit design scheme: the 5G communication circuit mainly composed of LS2160 chip, FSM9955 chip and FTR8900 chip, not only realizes the target function of the 5G communication circuit (simultaneously realizing 4G and 5G communications), but also ensures stable and continuous communication of the 5G communication circuit under the premise of using minimal hardware resources, effectively reducing hardware costs.
